The standard was changed from the original 145.4- to the capital industry standard. Important technical content of the original standard has changed. Explanation of sales status
The original chain machine series products were included in the five-chain category, and now all are included in the category 1. The original classification series machines are relatively wide, and the description is relatively poor and inconvenient. Now the sheep or difficult-line chain stitch machine series is classified into the K classification. The decorative line series is included in the K2 classification. The series of machines with single-line and blue chain ratios are included in the K3 classification: the series of machines with the ability to tear and connect stones are added! Classification: the original sewing machine model is removed. This standard introduces some definitions and terms (Japanese 4515-B4% of the stitch classification and terminology). The standard is proposed by the Quality Standards Department of China Light Industry Association. This standard is issued by the National Machinery Standardization Center. The originator of this standard is the Shanghai Machinery Research Institute. This standard is not the main originator. From the date of implementation of this standard, the same period B4514-84 whole smoke machine product model compilation is available. -TTTKNr Ka-

3.41 Straight load chain (see Figure 1)
QB/T2261—96
3.4,2 Industry analysis Line chains can be divided into the following three types. ) Z-shaped thread operation, continuous thread, on the key surface according to the fixed 7-shaped shadow arrangement of other thread alignment pressure 2), b) single curved thread chain: the continuous thread formation direction is consistent with the thread shape, and the thread chain is arranged on the material in a predetermined order (see Figure 3),
) effective curved thread chain: the thread shape of the continuous thread is in the same direction, some are in the opposite direction, and some are arranged in the reverse direction of the thread formation, and the thread key on the material is arranged in a predetermined order (see Figure 1). Home
84,3 Decorative carrier chain
24,4 Special carrier chain A number of continuous threads, a certain key to the evil request, arranged on the material 5 of the chain, such as creating a button, a button, adding a pattern, etc.
a.4,6 The stitches can only be recorded on one side of the stitch. According to the stitch type and generation, it can be subdivided into the following categories.
a) Stitch, shape:
Lock stitch, curved shape slightly difficult,
Single chain stitch, straight shape slightly chain,
Single line mirror stitch, curved shape dark;
. ) Double chain stitch, straight shape F) Double chain stitch, hidden stitch.
3.5 Sewing machine with a load carrier should follow the best needle level or calibration line rate in the process of forming the continuous stitch! The thread is broken, and the thread is brought into the static thread to grab some keys or parts, or the thread is broken and transmitted to the zero line of the final position. In the formation of the lock stitch or stitch frequency machine: the hook machine needle forms a loop, and the original can be connected back to the calibration line 8.6.1 rub relatively

Because they pass through the loop together, the hook thread parts of the swinging motion. 3,5,2 are embedded in the shape lock type high-speed sewing machine. The hook formed by the cutting agent makes it pass through the green cause of the suspected polar line, and it does not wear the ring according to the load, and does the rotating hook and war lifting parts. 3.5,8 hook, in the formation of continuous continuous change to avoid the machine, the body wears the whole end, the shape is similar, in the shape of the line, do space complex rotation movement, the needle or other parts form the line loop, the special hook level parts or the next cycle of the machine plan enters the line loop formed by itself, and then retreats with its own level, 3,6,4 line hook on the formation of the base type load speed training machine, the original does not carry the cloth defect, as a hook (or fork) exhaustion, the transmission of the hook thread of the ring.
35 ,5 When the hook needle forms a chain line, the hook is cut and the parts are worn in sequence. 3.36 The collar and the stack are divided into the following three types: a) Horizontal, the center of gravity or the center of gravity of the machine body is parallel to the plane of the machine body: b) Vertical: The center of gravity of the machine body is rotated or can rotate, and the center of gravity of the machine body is higher than the working plane of the machine body: e) The machine is excited, and the axis of rotation or the axis of rotation is continuously operated, and the front is inclined to the working plane of the machine body. 3.6 When the light line type machine forms a chain line, the actuator is used to realize the loading and recovery of the soft line, as well as the type of tightening the line.
5.日.1 The cam in the wire picking wheel drives the wire selection component to realize the wire touching action. 3.6.2 The connecting rod wire adopts the connecting rod type to replace the moving picking object to realize the sugar destruction action, and the parts are generally the connecting rod of the crankshaft grip mechanism.
Name, 8, 3 The thread picking is realized by connecting rod mechanism or goose thread uniformity. This single thread type picking part is generally a crank lever mechanism.
3, 6.4 The rotation continues to use the rotating motion of the disk to realize the thread picking action. 3. The needle lamp (the horizontal needle, the part that moves in line with the needle) or the picking part directly fixed on the needle bar is used to realize the thread picking movement.
s.7 The shape of the machine head refers to the shape of the machine body that is related to the seam material part (see table!). The machine body shape is divided into the following types: () flat type. The shape of the supporting material part is a smooth plate. When installed on the sewing machine mold, the supporting material and the surface of the plate are basically on one plane: b) Platform type: The shape of the supporting material part is a flat plate. When installed on the sewing machine, it is a platform with a lower plate:
Old type: The shape of the supporting material part is a simple shape, such as a hand hanging from the side of the machine body. d) Projection type, the shape of the supporting part is a micro-shape, and the sub-arm extends from one side of the machine body.
) Textile type: The shape of the supporting sewing part is like a vertical recommendation under the machine body: F) Box type: The machine body is a box that supports the material part: ) Convertible type: The shape of the supporting material part is The shape can be changed according to industry requirements: as shown in my figure

1,9 Sewing machine control machine The continuous line changes in the material table according to a certain rule. 3.9.1. Machine control method uses the machine city (control wheel) method to change the continuous line. This is the direction of the material on the surface of the engraving. The main machine model control type can be divided into the following types. 1. Fixed type, using fixed group control, installed dry machine sample, when working, just check the lock lever (or can be light), so that the line continues to change according to a certain program b) portable or, during operation, the control cam can be adjusted as needed, different new, so that the sewing program can be changed,
3.9.2 Microcomputer sequence control adopts the principle of microcomputer program control to realize the automation of the operation, KoNrKAa
