Description

Technical Field

[0001] The utility model relates to the technical field of bag making machines, in particular to a bag making machine for producing wrinkle-proof food bags. Background Art

[0002] Bag making machine is a machine for making various plastic packaging bags or other material packaging bags. Its processing range is packaging bags of various sizes, thicknesses and specifications of plastics or other materials. Generally speaking, plastic packaging bags are the main products.

[0003] In the process of making food bags by a bag making machine, the processed food bag raw materials need to be rolled up to facilitate subsequent processing or transportation of the food bags. In the prior art, the food bags are mostly rolled up by automatic winding rollers and other winding equipment, and the winding efficiency is high. However, in the actual rolling process, wrinkles are prone to appear on the food bags, which affects the effect of rolling up the food bags. Because the food bag raw materials themselves are similar to plastic films and have strong continuity, wrinkles or even folds at a certain position or time are often followed by continued folding or wrinkling, which affects the production effect of the food bags and is not practical enough. Therefore, it is necessary to redesign a wrinkle-proof food bag production bag making machine to address the above problems. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a bag-making machine for producing wrinkle-proof food bags.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] Preferably, the connection mechanism comprises a connection spring installed inside the connection sleeve, and two ends of the connection spring are respectively fixedly connected to the inner wall of the connection sleeve and the outer wall of the connection rod.

[0008] Preferably, the support mechanism comprises two support plates fixedly mounted on the upper end surface of the bottom plate, and the lower pressure roller is rotatably mounted between the two support plates.

[0009] Preferably, a first fixing plate cooperating with one end of the winding roller is fixedly mounted on the outer wall of the rotating shaft, and a second fixing plate cooperating with the other end of the winding roller is rotatably mounted on the outer wall of the rotating shaft through a thread.

[0010] Preferably, a connecting plate is fixedly mounted on the upper surface of the base plate, and a fan is fixedly mounted on the outer wall of the connecting plate.

[0011] Preferably, a U-shaped blowing pipe is fixedly installed on the outer wall of the blower outlet pipe, and the outer wall of the U-shaped blowing pipe is provided with two blowing ports connected to the interior.

[0012] Beneficial effects of the utility model:

[0013] 1. By setting components such as a screw, a movable sleeve, a lower pressure roller and an upper pressure roller, the screw drives the movable sleeve to move by cooperating with the limit rod, and the movable sleeve drives the upper pressure roller to move downward by cooperating with the connecting frame, and the upper pressure roller and the lower pressure roller are brought close to each other to roll the food bag, thereby flattening the wrinkles of the food bag to avoid affecting the production effect of the food bag.

[0023] A connecting rod 11 is slidably installed inside the connecting sleeve 9 through a connecting mechanism. The connecting mechanism includes a connecting spring 10 installed inside the connecting sleeve 9. The two ends of the connecting spring 10 are respectively fixedly connected to the inner wall of the connecting sleeve 9 and the outer wall of the connecting rod 11. A connecting frame 12 is fixedly connected to the end of the connecting rod 11. An extrusion roller 13 is rotatably installed inside the connecting frame 12. A lower pressure roller 15 is rotatably installed on the upper end surface of the base plate 1 through a supporting mechanism. The supporting mechanism includes two support plates 14 fixedly installed on the upper end surface of the base plate 1, and the lower pressure roller 15 is rotatably installed between the two support plates 14.

[0024] A screw 17 is rotatably installed on the upper end surface of the base plate 1 through a lifting frame 16, and a second motor 18 connected to the screw 17 is fixedly installed on the upper end surface of the lifting frame 16. A moving sleeve 20 is threadedly installed on the outer wall of the screw 17. A limiting rod 19 is fixedly installed inside the lifting frame 16, and the limiting rod 19 slides through the moving sleeve 20. The limiting rod 19 can limit the moving sleeve 20 so that the moving sleeve 20 can only move axially along the outer wall of the screw 17. A connecting frame 21 is fixedly installed on the outer wall of the moving sleeve 20, and an upper pressure roller 22 is rotatably installed inside the connecting frame 21.
