Description

Technical Field

[0001] The utility model relates to the field of fully automatic bag-making equipment, and particularly relates to a secondary breaking device and a production line for processing a one-bottom express paper bag. Background Art

[0002] In the express delivery industry, the selection of packaging materials is particularly important. With the rapid development of the e-commerce industry, express paper bags, as a common packaging form, are widely used due to their environmental protection, low cost and other characteristics. However, in the current production process, there are still some technical bottlenecks that limit its production efficiency.

[0003] Such as Figure 3 As shown, in express paper bags, one type is the paper bag with a tongue length at the front end and a bottom folding size to be reserved at the rear end. During the production of this kind of paper bag, a single-sheet die-cutting production mode is mostly adopted. When using a single sheet of paper to produce a paper bag, usually the original paper bag needs to be die-cut and creased to form a paper blank that conforms to the unfolded drawing of the paper bag, so as to facilitate the subsequent paper bag machine to make paper bags. In this single-sheet die-cutting production mode, a large amount of manual participation is required before the production of paper bags, and the production efficiency is extremely low.

[0004] A processing production line for a one-bottom express paper bag with the application number "2024219892438" has changed the traditional single-sheet die-cutting production mode of paper bags. Specifically: using this paper bag processing equipment, it is not necessary to prepare a batch of single-sheet paper bag raw materials in advance. This equipment realizes the full-automatic processing of paper bags from raw materials to finished products. The utility model is a secondary breaking device for a one-bottom express paper bag processing production line. Summary of the Invention

[0005] Therefore, the utility model is a secondary breaking device for a one-bottom express paper bag processing production line. Through this device, it aims to improve the accuracy and stability of breaking, ensure the accurate breaking position, and effectively handle the waste generated during the breaking process, thereby improving the overall production efficiency and the quality of paper bags. The utility model realizes the above purpose through the following technical solutions:

[0006] A secondary breaking device for a processing production line of an L-shaped bottom express paper bag, comprising: a transmission device and a breaking device. The transmission device includes: a first gear, a first transmission gear, a second gear, a second transmission gear, and a third gear. The first gear, the first transmission gear, the second gear, the second transmission gear, and the third gear are meshed in sequence from left to right. The breaking device includes: a paper pressing roller, a first breaking roller, a second breaking roller, a lower paper pressing roller, a first lower breaking roller, and a second lower breaking roller. The first gear is in transmission connection with the lower paper pressing roller, the second gear is in transmission connection with the first lower breaking roller, and the third gear is in transmission connection with the second lower breaking roller. A plurality of adjusting holes are formed on the circumferential surface of the paper pressing roller, and a fixed paper pressing friction block and a movable paper pressing friction block are respectively installed on the adjusting holes. An upper breaking block one is provided at the lower end of the first breaking roller, and a lower breaking block one is provided at the upper end of the first lower breaking roller. An upper breaking block two is provided at the lower end of the second breaking roller, and a lower breaking block two is provided at the upper end of the second lower breaking roller. A vacuum suction nozzle is installed on one side of the upper breaking block two and on the second breaking roller, and a waste discharging pipeline is provided above the second breaking roller.

[0007] Preferably, both the first gear and the third gear are connected by an expansion sleeve.

[0008] Preferably, the first gear, the first transmission gear, the second gear, the second transmission gear, and the third gear are located outside the processing equipment.

[0009] Preferably, the paper pressing roller, the first breaking roller, the second breaking roller, the lower paper pressing roller, the first lower breaking roller, and the second lower breaking roller are all located inside the processing equipment.

[0010] Preferably, both the lower breaking block one and the lower breaking block two are steel parts with knurling.

[0011] The present utility model also provides a processing production line of an L-shaped bottom express paper bag, which includes the secondary breaking device for the processing production line of the L-shaped bottom express paper bag, and further includes: a loading rack, a deviation rectifying mechanism, a pre-piercing device, a gluing mechanism, a release paper pasting mechanism, a tube forming mechanism, a breaking mechanism, a bottom gluing mechanism, a folding mechanism, and a bag discharging mechanism arranged in sequence along the production line. In this production line, the loading rack, the deviation rectifying mechanism, the pre-piercing device, the gluing mechanism, the release paper pasting mechanism, the tube forming mechanism, the bottom gluing mechanism, the folding mechanism, and the bag discharging mechanism are all prior arts of a bag making machine, and the breaking mechanism is located on one side of the bottom gluing mechanism.

[0012] Advantages of the present utility model:

[0013] 1. Compared with the prior art of breaking by clamping rollers, in the process of primary breaking, the extrusion of the paper bag by a flexible material in the present utility model increases the friction force with the paper bag, making the breaking more stable and not prone to slipping. In the process of secondary breaking, automatic waste removal can be realized, which improves the production efficiency compared with the manual waste removal in the traditional single-sheet die-cutting production mode.

[0014] 2. Both groups of the pull - off blocks of the present utility model are steel parts with knurling, which increases the friction between the pull - off blocks and the paper bag, making the paper bag more stable during the pull - off process, improving the success rate of pull - off, and avoiding defects in the finished paper bag.

[0015] 3. The position of the secondary pull - off of the present utility model can be adjusted according to the length requirement of the paper bag. By adjusting the distance between the fixed paper - pressing friction block and the movable paper - pressing friction block, it can meet the requirements of different bag lengths and tongue lengths.

[0016] 4. The present utility model uses a vacuum suction nozzle to adsorb the pull - off waste, and then discharges it through the waste - discharging pipeline. Without affecting the normal operation of the machine, the waste generated during the pull - off process can be effectively treated. Description of the Drawings
