Abstract
Description
Technical Field
[0001] The utility model relates to the field of fully automatic bag-making equipment, and particularly relates to a processing production line for one-word bottom express paper bags. 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 the 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 type of paper bag, a single-sheet die-cutting production mode is mostly adopted. When using a single sheet of paper for paper bag production, usually the original paper bag needs to be die-cut and creased to form a paper blank that conforms to the paper bag unfolding diagram 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 paper bag production, and the production efficiency is extremely low. Summary of the Invention
[0004] Therefore, the utility model is a processing production line for one-word bottom express paper bags. This equipment realizes the full-automatic processing of paper bags from raw materials to finished products. The utility model achieves the above object through the following technical solutions:
[0005] A processing production line for one-word bottom express paper bags, the production line 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 bottom folding mechanism, and a bag discharging mechanism. The loading rack is located at the front end of the entire production line and is used for loading the raw materials of the paper bags. The deviation rectifying mechanism is located at the end of the loading rack. The function of the deviation rectifying mechanism is to ensure that the position of the paper does not shift during the transportation of the paper bags. Above the deviation rectifying mechanism is provided with a pre-piercing device. Above the pre-piercing device are provided with a gluing mechanism and a release paper pasting mechanism. The tube forming mechanism is located on one side of the pre-piercing device, and on the other side of the tube forming mechanism is provided with a breaking mechanism. The breaking mechanism includes: a paper pressing roller, a paper pressing friction block, a breaking block, a first breaking roller, a second breaking roller, and an adsorption mechanism. The paper pressing roller is divided into upper and lower two parts. The upper paper pressing roller is provided with a paper pressing friction block. On one side of the paper pressing roller is installed a first breaking roller. The first breaking roller is divided into upper and lower two parts. On both the upper and lower first breaking rollers are provided with breaking blocks. On the side of the first breaking roller away from the paper pressing roller is installed a second breaking roller. On one side of the breaking mechanism are provided with a bottom gluing mechanism and a bottom folding mechanism. The bag discharging mechanism is located at the rear end of the entire production line.
[0006] Preferably, the pre-piercing device includes: a pre-piercing roller, a tool holder, an adjusting seat, a motor, a synchronous pulley, and a pre-piercing knife. The tool holder is mounted on the pre-piercing roller and is used to set the pre-piercing knife. An adjusting seat is provided at one end of the pre-piercing roller, and a motor is provided on one side of the pre-piercing roller. The synchronous pulley is sleeved on the other end of the pre-piercing roller.
[0007] Preferably, the pre-piercing roller is provided with threaded holes, and the tool holder has matching waist slots, so that the position of the tool holder can be adjusted. An adjusting mechanism is provided on the side of the pre-piercing roller close to the synchronous pulley. Through the adjusting mechanism, the position of the rubber roller for conveying the paper bag can be adjusted, and thus the depth of the piercing holes can be controlled.
[0008] Preferably, an adsorption mechanism is installed on the outer side of the second breaking roller, and the adsorption mechanism can adsorb the waste generated during the secondary breaking process.
[0009] Preferably, the paper pressing friction block can be made of a flexible material with a large frictional force, such as rubber or silica gel.
[0010] Preferably, embossing or patterns are added to the paper pressing roller without the paper pressing friction block.
[0011] Preferably, the breaking block adopts a knurled structure of steel parts.
[0012] Advantages of the present utility model:
[0013] 1. By changing the traditional single-sheet die-cutting production mode and adopting this paper bag processing equipment, it is not necessary to prepare a large number 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, significantly improving the production efficiency.
[0014] 2. The pre-piercing depth of the paper bag can be adjusted by the pre-piercing device of the present utility model, which can not only meet the piercing requirements of paper bags with different thicknesses, but also improve the piercing effect by adjusting the piercing depth for paper bags with the same thickness, increasing the success rate of subsequent breaking of the paper bag, and thus improving the production efficiency of the paper bag.
[0015] 3. Compared with the existing technology of breaking by clamping rollers, in the process of the first breaking of the present utility model, the extrusion of the paper bag by the flexible material increases the frictional force with the paper bag, making the breaking more stable and not prone to slipping. In the process of the second breaking, the waste can be automatically removed, greatly improving the production efficiency compared with the manual removal of waste in the traditional single-sheet die-cutting production mode.
