Technical Field

[0001] The utility model relates to the technical field of bag making equipment, in particular to a PE bag making and clamping device. Background Art

[0002] PE is the abbreviation of polyethylene, which is a thermoplastic resin obtained by polymerization of ethylene. In industry, it also includes copolymers of ethylene and a small amount of olefins. It is a transparent plastic bag that can be used for packaging of clothing, bags, electronic products, etc. In the process of rolling up PE bags, since the back of the edge of the PE bag needs to be punctured when the edge is sealed to facilitate tearing, when the PE bag is subjected to uneven force during the rolling process, it often breaks. Therefore, a PE bag processing clamping device is needed.

[0003] The application number retrieved is: CN202120881651.1, a PE bag making and clamping device, which reduces the space occupied by the clamping device during storage.

[0004] However, the existing PE bag clamping device still has certain defects in actual use: after completing the edge sealing of the PE bag, when the PE bag is rolled up, when the weak parts connected to the PE bag are pulled, they often break, resulting in the need for manual intervention during the subsequent rolling of the PE bag, which slows down the rolling progress of the PE bag. For this reason, we propose a PE bag processing clamping device. Utility Model Content

During the edge sealing process of the PE bag, the rear of the edge sealing of the PE bag is punctured for the subsequent use of the PE bag and convenient tearing. The placement plate 2 is located below the smoothing component 6 and a second support plate 17 is arranged, and a second drive motor 18 is used to drive the smoothing component 6 to rotate, and a second drive motor 18 is placed above the second support plate 17. Two groups of telescopic columns 8 are arranged above the inner wall of the edge sealing box 7, and an edge sealing plate 9 is arranged below the two groups of telescopic columns 8.

[0023] The clamping assembly 3 includes a first crawler 10, a limiting groove 11, a clamping block 12 and a first connecting shaft 13, and the outer surface of the first crawler 10 is provided with a limiting groove 11, and the limiting groove 11 is used to connect with the plug-in block 21 of the clamping block 12, and is used to fix the clamping block 12. At the same time, different spacings are used to adapt to different distances of PE bags. The clamping block 12 is arranged above the limiting groove 11, and the clamping block 12 is arranged below the placement groove. 21, and a second clamping rod 20 is arranged above the plug-in block 21, and the second clamping rod 20 and the first clamping rod 19 are used to clamp the upper and lower sides of the PE bag to maintain the transportation of the PE bag, thereby avoiding the accumulation of the PE bag, the first clamping rod 19 is arranged above the second clamping rod 20, and the end of the first clamping rod 19 is arranged with a second stepping motor 24, and the second clamping rod 20 is arranged with an extension sleeve 2001 on the side away from the second stepping motor 24, and the first crawler 1 When the clamping block 12 is driven by the second clamping rod 20 to reach the area of ​​the PE bag, the extension sleeve 2001 of the second clamping rod 20 is contracted, so that the first clamping rod 19 contacts the outer surface of the PE bag. After the first clamping rod 19 contacts the PE bag, the second clamping rod 20 ejects the extension sleeve 2001, so that the first clamping rod 19 and the second clamping rod 20 clamp the PE bag. After clamping to the end, the extension sleeve 2001 of the second clamping rod 20 is retracted, which facilitates the first clamping rod 19 to continue to extend. The first crawler 10 moves, and the PE bag is continuously clamped by the first clamping block 12 on the first crawler 10, thereby completing the transportation of the PE bag.

[0025] In summary, the utility model uses the conveying platform 1 and the clamping component 3. When the PE bag enters the edge sealing box, the heat sealing knife arranged at the center of the edge sealing plate inside the edge sealing box will melt the contact area of ​​the two PE bags when it contacts the PE bag, thereby fusing the two PE bags together to complete the edge sealing of the PE bag. After the edge sealing box 7 seals the PE bag, the clamping component 3 drives the PE bag to move forward, and in the process of moving downward, the PE bag contacts the smoothing component 6. In the process of continuous movement of the PE bag, the outer surface of the PE bag contacts the second track 27 of the smoothing component 6 and is smoothed, so that when it contacts the subsequent clamping component 3, wrinkles will not appear on the two ends of the PE bag, resulting in the inability to clamp during the subsequent clamping. When the PE bag is conveyed to the top of the conveying platform 1, the clamping components 3 on both sides of the conveying platform 1 are driven by the first driving motor 16 drives the first crawler 10 inside the clamping assembly 3 to rotate, and during the rotation process, the clamping block 12 is placed in the limit groove 11 on the first crawler 10, so as to complete the clamping of PE belts of different lengths, and when the clamping block 12 contacts the PE bag, the delay sleeve on the outer surface of the second clamping rod 20 shrinks, so that the first clamping rod 19 contacts the top of the PE bag, and after the contact is completed, the extension sleeve 2001 of the second clamping rod 20 is extended and pushed out, so as to complete the clamping of the PE bag, and after the PE bag is fixed, the first crawler 10 is driven by the connecting shaft to move, thereby driving the PE bag to move, and when the PE bag moves to the end, the subsequent clamping block 12 contacts the PE bag, and at the same time, the front clamping block 12 shrinks the extension sleeve 2001 back into the clamping block 12, so as to avoid the clamping block 12 from tearing the PE bag during recycling.
