Abstract
Description
Technical Field
[0001] This utility model belongs to the field of packaging bag cutting technology, specifically a packaging bag conveying and cutting mechanism. Background Technology
[0002] After processing, sausages need to be packaged by a packaging machine. Specifically, the sausages are pushed into a formed film tube, and the film is rotated to package the sausages. Then, the film tube is heat-sealed at both ends of the sausages to form a continuous package. Subsequently, the connected packaging bag is cut into individual sausage packages by a cutting mechanism.
[0003] Currently, packaging bags are typically cut using horizontally moving cutting heads. However, these cutting heads require replacement and maintenance after prolonged use. They are usually secured with bolts, which are prone to wear or loosening during use, potentially causing the cutting head to detach or become damaged. This reduces the cutting efficiency of the packaging bags. Furthermore, when the packaging bag material is subjected to cutting force, tiny cracks or peeling may occur at the edges or inside, easily generating debris. This debris can easily scatter on the production line or work area, increasing cleaning difficulty. Therefore, we propose a packaging bag conveying and cutting mechanism. Utility Model Content

[0018] In the scheme of this application:
[0019] 1. By setting a connecting block on the threaded block, the connecting block is set in the connecting groove on the mounting block. The connecting block is locked in the connecting groove by the limiting rod and the limiting hole. When the cutting head needs to be disassembled and repaired, the positioning component is moved, so that the positioning block loses its limit. The connecting plate drives the limiting rod to move. At this time, the limiting rod moves out of the limiting hole, so that the connecting block loses its limit. This realizes the separation of the connecting block and the mounting block, which facilitates the disassembly and assembly of the cutting head, reduces the occurrence of the cutting head falling off or being damaged, and improves the cutting efficiency of packaging bags.

An elastic element for limiting the positioning rod 251 is provided on the support plate 250. The positioning block 261 is limited by the positioning rod 251 cooperating with the positioning hole.
[0036] Please see Figure 3 and Figure 4 The elastic element includes a spring 253. An adjusting block 252 is fixedly connected to the top of the positioning rod 251. The spring 253 is fixedly connected between the bottom of the adjusting block 252 and the top of the support plate 250. The spring 253 applies a downward force to the adjusting block 252 and the positioning rod 251.
[0037] Please see Figure 1 The top of the operating table 100 is fixedly equipped with a conveyor belt for conveying packaging bags, and the packaging bags are conveyed by the conveyor belt.
[0038] Please see Figure 1The top of the operating table 100 is fixedly connected to a packaging machine for packaging sausages. The packaging machine is existing technology. Specifically, the sausage is pushed into a formed film tube, and the sausage is wrapped by rotating the film. Then the film tube is heat-sealed at both ends of the sausage to form continuous packaging and complete the sausage packaging.
[0039] Specifically, in use, the packaging bag conveying and cutting mechanism is first powered on. After the sausage is packaged by the packaging machine, the packaging bag is transported by a conveyor belt. Then, the electric slide table 110 drives the support frame 200 to move, and the motor 221 drives the threaded rod 220 to rotate. The threaded rod 220 drives the mounting block 240 and the cutting head 243 to move through the connecting block 231. The cutting head 243 cuts the packaging bag. At this time, the vacuum cleaner 120, through the connecting pipe 212 and the telescopic hose 130, sucks the debris into the vacuum head 211. Inside, the debris is stored in the collection box 140. When the cutting head 243 needs to be disassembled and repaired, the adjusting block 252 is pulled, which drives the positioning rod 251 to move longitudinally and move the positioning rod 251 out of the positioning hole. At this time, the positioning block 261 loses its limit and drives the limiting rod 263 to move through the connecting plate 262, so that the limiting rod 263 moves out of the limiting hole 242. At this time, the connecting block 231 loses its limit and moves out of the connecting groove 241, thus realizing the disassembly of the mounting block 240 and the cutting head 243, and thus completing the use of the mechanism.
