3 Technical requirements before product packaging
3.1 Belt conveyor product parts can only be packaged after they have passed the inspection. 3.2 Prepare the packing list according to the requirements of the product design drawings and process documents. The contents of the packing list should include the product name, component drawing number, quantity, packaging form, box number and weight, etc. 3.3 The oil, water, and debris on the surface of the parts should be cleaned, and the metal processing surface should be sealed for rust prevention according to the relevant requirements of GB4879 rust-proof packaging.
3.4 The pipe joints and flange joints on the product must be plugged with plugs, and the external threaded parts must be wrapped with oil-soaked linen and tied with wire, and marked or numbered. Purchased parts such as wire ropes should be oiled and wrapped with oil paper or plastic paper. 4 Technical requirements for box packaging and bare packaging
4.1 The packing construction personnel should pack according to the packing list and check the items, quantities and specifications listed in the packing list one by one with the actual objects. 4.2 Under normal storage, transportation, loading and unloading conditions, it should be ensured that the product parts should not rust, grow mold, reduce precision, be damaged or lost due to poor packaging for at least 12 months from the date of shipment. Special requirements shall be implemented according to the agreement between the supply and demand parties. 4.3 When placing product parts in the box, the center of gravity should be as centered and low as possible. If the center of gravity is obviously too high, appropriate balancing measures should be taken.
4.4 The distance between the inner wall of the box and the parts should not be less than 30mm, and the distance from the top of the box should not be less than 50mm. Parts should be fixed in the box. The fixing methods can be cushioning materials, wooden blocks, bolts, and pressure bars. Large parts should be reliably fixed to the base of the box with bolts. If the fixing bolts pass through slides or sleepers, the bolt heads and washers at the bottom should be sunk into the drilled pit. 4.5 For parts that need to be stacked and packaged, those with low precision, high weight, and large volume should be placed at the bottom. 4.6 When packing parts with high processing precision or parts that are easily damaged by knocks or collisions, cushioning measures should be taken.

4.7 When packing small parts (such as fasteners, etc.), they should be packed in paper boxes, wooden boxes, sacks, or plastic bags before being placed in a safe position in the box.
4.8 Single motors and various electrical equipment should be packed with moisture-proof measures. 4.9 If there are moving or shaking parts in single bare parts, they should be fixed. 4.10 The packaging of bare parts (including bundled parts) should be firm and should not be loose due to long-distance transportation and multiple loading and unloading. 4.11 Use containers (or iron turnover boxes) for packaging and shipment as much as possible. 4.12 In one packaging box or multiple bundled bare parts, only parts of the same contract number product can be packaged, and labels indicating the name, code, quantity, etc. of the part should be tied on the parts. Parts of the same size and specification should be packaged together. Mixing of parts of several contract numbers is not allowed.

The markings should be correct, neat and clear.
JB/T 2647 - 95
9.3 The packaging of bare and bundled items should be firm and free of looseness. 10 Packaging box test methods
10.1 For newly designed packaging boxes, when there are major changes in packaging materials or box structures, lifting tests, rain tests and stacking tests must be carried out in accordance with GB/T4857.9 and GB5398, and they can only be used after being identified as qualified. 10.1.1 Lifting test
After the parts are packed, lift them according to the designed lifting position, with the angle between the lifting rope and the box surface being 45°~50°, lift them to a certain height (not less than 1500mm), start and brake them urgently, move them left and right for 3~5min, lift and lower them 3 times, and the box body shall not be damaged or deformed obviously. 10.1.2 Rain test
Place the test box (empty box) horizontally, spray it vertically downward evenly with a water volume of 100L/(m2·h), with the distance between the water spray device and the top surface of the box not less than 2000mm, and the spraying time is 1h. After the test, open the box for inspection, and there shall be no water seepage in the box. 10.1.3 Stacking test
Place the loaded test box on a flat cement floor, and evenly stack sand and gravel on the top of the box so that the top load of the box is not less than 500kg/m2, and the stacking time is 24h. After the test, the box body shall not be deformed or damaged obviously. Additional Notes:
This standard was proposed and managed by the Beijing Hoisting and Conveying Machinery Research Institute of the Ministry of Machinery Industry. This standard was drafted by Shanghai Hoisting and Conveying Machinery. The main drafters of this standard were Jiang Ming and Yang Shoufa.5 The gross weight of each box should be controlled below 9000kg as far as possible. If it exceeds 9000kg, the words "heavy and bulky goods" should be marked on the box surface. 8.6 All packages that need to be lifted and whose center of gravity is obviously off the center should be marked with "lift from here" and "center of gravity". 8.7 The packaging storage and transportation diagrams should comply with the relevant provisions of GB191. 8.8 When the product is packed in boxes, the box number is expressed as a fraction, with the numerator being the box number and the denominator being the total number of boxes. 9 Acceptance rules
9.1 Before sealing the packaging box, the packaging inspector should check the specifications and quantity of the product parts and components and the correctness of the random technical documents, marks, etc. according to the packing list and relevant technical documents. After inspection and proofreading, the packer and the inspector should sign on the packing list before sealing the box. 9.2 After the packaging box is packed, it should meet the following requirements: a. There should be no obvious gap at the intersection of the side end faces of the wooden box; b. Steel nails cannot be bent in the middle or the nail tips can be exposed outside; c.
The oxidized thin steel strips used to reinforce wooden boxes should be flat and firm; the lids of containers or turnover boxes should be tightly sealed; d.
The markings should be correct, neat and clear.
