Description

Technical Field

[0001] The utility model relates to the field of fully automatic bag-making equipment, and particularly relates to a pre-piercing device and a production line for a processing production line of an L-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 a 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 scored first 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 paper bag production, and the production efficiency is extremely low.

[0004] A processing production line of an L-bottom express paper bag with the application number of "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 pre-piercing device for a processing production line of an L-bottom express paper bag. Summary of the Invention

[0005] Therefore, the utility model is a pre-piercing device for a processing production line of an L-bottom express paper bag. By driving the rubber roller to swing through the lower end of the swing arm, the gap between the rubber roller and the pre-piercing roller can be adjusted, and the piercing depth of the pre-piercing knife can be adjusted. The utility model realizes the above purpose through the following technical solutions:

[0006] A pre-piercing device for a processing production line of an L-bottom express paper bag, comprising: a pre-piercing roller, a tool holder, an adjusting seat, a motor, a synchronous pulley, and a bracket. There are two brackets, and the two brackets are used to support both ends of the pre-piercing roller. A tool holder is installed on the pre-piercing roller, and the tool holder is used to set the pre-piercing knife. An adjusting seat is arranged at one end of the pre-piercing roller, a motor is arranged inside the bracket, and the synchronous pulley is sleeved on one end of the pre-piercing roller; a worm is arranged at the upper end outside the bracket, a worm gear is arranged at the upper end of the worm, a central shaft penetrates through one side of the bracket, eccentric bushings are sleeved at both ends of the central shaft and located inside the bracket, a swing arm is arranged at the lower end of the eccentric bushing, the middle position of the swing arm is movably installed on the bracket through a pin shaft, a rubber roller is arranged at the lower end of the swing arm, and an installation hole matching the rubber roller is opened on the bracket.

[0007] Preferably, the pre-piercing roller is provided with threaded holes, and the tool holder has a matching waist groove, so that the position of the tool holder can be adjusted.

[0008] Preferably, the pre-piercing knife is composed of a straight knife and an arc knife, and is equipped with a corresponding tool holder.

[0009] Preferably, the worm is meshed with the worm, and the worm is driven to rotate by an external handle. The worm is fixedly installed on the bracket through two fixing blocks.

[0010] Preferably, the center position of the worm gear is connected to the bracket through a central shaft.

[0011] The utility model also provides a processing production line for express delivery paper bags with a flat bottom, which includes the pre-piercing device of the processing production line for express delivery paper bags with a flat bottom, and also includes: a loading rack, a deviation rectifying mechanism, a gluing mechanism, a release paper pasting mechanism, a tube forming mechanism, a first breaking mechanism, a second breaking mechanism, a bottom gluing mechanism, a folding mechanism, and a bag discharging mechanism arranged in sequence along the production line.

[0032] The pre-piercing knife 36 is composed of a straight knife 362 and an arc knife 361, and is provided with a corresponding knife holder 32;

[0033] One end of the pre-piercing roller 31 is provided with an adjusting seat 33, and the adjusting seat 33 can finely adjust the horizontal position of the pre-piercing roller 31, so that the position of the paper bag and the pre-piercing roller 31 is more fitting;

[0034] A motor 34 is arranged inside the bracket 37. The motor 34 drives the synchronous pulley 35 to rotate by driving the rotation of the belt, and the synchronous pulley 35 is sleeved at one end of the pre-piercing roller 31;

[0035] A worm 38 is arranged at the upper end of the outer side of the bracket 37, and the worm 38 is installed on the bracket 37 through two fixing blocks;

[0036] A worm gear 39 is arranged at the upper end of the worm 38. The worm gear 39 meshes with the worm 38. By driving the worm 38 to rotate through an external handle, the worm gear 39 at its upper end can be driven to rotate accordingly;

[0037] The center position of the worm gear 39 and the bracket 37 are connected through a central shaft 310;

[0038] The central shaft 310 penetrates through one side of the bracket 37, and eccentric bushings 311 are sleeved at both ends of the central shaft 310 and inside the bracket 37. The rotation of the central shaft 310 can drive the eccentric bushings 311 to rotate;

[0041] Embodiment 2:

[0042] As Figure 1 、 2 、shown in FIG. 3, the present invention also provides a processing production line for one-word bottom express paper bags, which includes the pre-piercing device of the processing production line for one-word bottom express paper bags described in Embodiment 1, and further includes: a loading rack 1, a deviation rectifying mechanism 2, a gluing mechanism 4, a release paper pasting mechanism 5, a tube forming mechanism 6, a first breaking mechanism 7, a second breaking mechanism 8, a bottom gluing mechanism 9, a folding mechanism 10, and a bag discharging mechanism 11 arranged in sequence along the production line.

[0043] Working principle of the utility model:

[0044] When the web runs to the pre-piercing roller 31, the motor 34 drives the synchronous pulley 35 to rotate, so that the synchronous pulley 35 drives the pre-piercing roller 31 to rotate. Since the rubber roller 313 is a passive roller, it rotates with the paper. When it is necessary to adjust the gap between the rubber roller 313 and the pre-piercing roller, the external handle is used to drive the worm 38 to rotate, so that the worm 38 drives the worm wheel 39 to rotate. Then, the worm wheel 39 drives the central shaft 310 to rotate. The rotation of the central shaft 310 drives the eccentric bushing 311 to rotate, and the eccentric bushing 311 drives the upper end of the swing arm 312 to swing. Since the middle position of the swing arm 312 is limited by the pin shaft 314, the lower end of the swing arm 312 drives the rubber roller 313 to swing, thereby adjusting the gap between the rubber roller 313 and the pre-piercing roller 31, and the piercing depth of the pre-piercing knife 36 can be adjusted.
