After lamination and printing, they have better color performance. Since the film seals the bag after lamination, and the actual use requires the bag to be breathable, it is necessary to process micropores for ventilation on the formed woven plastic bags. In the prior art, for example, the utility model patent: a micropore punching device for woven plastic bags (publication number: 211616783U) discloses a device for punching woven plastic bags by needle punching on a needle punching plate. However, the above device requires manual loading and unloading of woven plastic bags when punching them, which is inconvenient to operate and not easy to connect to the woven plastic bag production line to achieve automated production.

[0003] To address the aforementioned problems, this utility model provides improvements. Utility Model Content

[0004] This utility model proposes a micro-hole punching device for the production of laminated color-printed woven plastic bags, which solves the above-mentioned problems existing in the use of the prior art.

[0022] The following will refer to the appendix in the embodiments of this utility model. Figure 1-6 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] As shown in the figure, a micro-perforation device for producing laminated color-printed woven plastic bags includes a frame 1. The frame 1 is equipped with a feeding mechanism 2 and a perforation mechanism 3. The feeding mechanism 2 includes an active feeding wheel 21 and a driven feeding wheel 22. The active feeding wheel 21 is rotatably arranged in two rows on the inner walls of the two side plates of the frame 1, and the active feeding wheel 21 is driven by a first motor 23 mounted on the frame 1. The drive connection between the active feeding wheel 21 and the first motor 23 is achieved through the cooperation of a synchronous pulley and a synchronous belt. Several driven feeding wheels 22 are rotatably arranged on the frame 1 and are vertically opposite to several active feeding wheels 21. The perforation mechanism 3 includes a needle-punching roller 31 with several rows of needles arranged on its circumferential surface. The needle-punching roller 31 is rotatably arranged between the two side plates of the frame 1 and is driven by a second motor 32 mounted on the frame 1.

[0024] In the above structure, the feeding mechanism 2 is connected to the forming device of the pre-formed laminated color-printed woven plastic bag. The two sides of the formed woven plastic bag enter the active feeding wheel 21 and the driven feeding wheel 22 on the two side plates of the frame 1, respectively, and are clamped by the active feeding wheel 21 and the driven feeding wheel 22. The first motor 23 drives the active feeding wheel 21 to rotate. The rotating active feeding wheel 21, together with the driven feeding wheel 22, drives the woven plastic bag to be conveyed backward. At the same time, the second motor 32 drives the needle roller 31 to rotate. When the woven plastic bag conveyed backward passes under the needle roller 31, the rotating needle roller 31 drives several rows of needles on its circumference to intermittently contact the woven plastic bag. The needles on the needle roller 31 and the needle roller 31... When the woven plastic bag comes into contact with the needle, the needle penetrates the bag to form micropores. As the woven plastic bag is conveyed by the active feeding wheel 21 and the driven feeding wheel 22 in conjunction with the rotation of the needle roller 31, multiple rows of micropores can be processed on the woven plastic bag, thereby realizing the micro-perforation of the woven plastic bag. The perforated woven plastic bag is then conveyed by the active feeding wheel 21 and the driven feeding wheel 22 to subsequent production processes such as palletizing and packaging. It can be seen that through the above structure, the micro-perforation processing of laminated color-printed woven plastic bags can be achieved efficiently and stably. At the same time, this perforation device can be well connected with the preceding and following production processes of the woven plastic bag production line, thereby realizing the automation of production, improving efficiency and saving manpower.

[0025] Furthermore, the punching mechanism 3 also includes a felt roller 33 with a felt pad layer on its circumferential surface. The felt roller 33 is rotatably disposed between the two side plates of the frame 1 and is vertically opposite to the needle-punching roller 31. The plastic woven bag being conveyed passes between the needle-punching roller 31 and the felt roller 33 and passes under the needle-punching roller 31. When the plastic woven bag passes under the needle-punching roller 31, it maintains contact with the felt roller 33. The felt roller 33 provides support for the plastic woven bag when the needle-punching roller 31 punches the plastic woven bag, preventing the plastic woven bag from becoming loose and deformed due to force, thereby ensuring the stability and quality of the punching process.

[0026] Furthermore, the feeding mechanism 2 also includes two feeding traction rollers 24. These two rollers are rotatably mounted between the two side plates of the frame 1, positioned opposite each other in front of the active feeding wheel 21. The lower feeding traction roller 24 is connected to a third motor 25 mounted on the frame 1. The woven plastic bag, after previous forming processes, enters between the two feeding traction rollers 24 before entering between the active feeding wheel 21 and the driven feeding wheel 22. The third motor 25 drives the lower feeding traction roller 24 to rotate, thus engaging the upper feeding roller 24. The square feeding traction roller 24 drives the woven plastic bag to be conveyed between the active feeding wheel 21 and the driven feeding wheel 22, ensuring that both sides of the woven plastic bag can stably enter between the active feeding wheel 21 and the driven feeding wheel 22, thereby ensuring the stability of feeding. In addition, while conveying the woven plastic bag, the two feeding conveying rollers squeeze the woven plastic bag to squeeze out the residual air inside the woven plastic bag, making the woven plastic bag more flat. This allows the needle to stably penetrate the woven plastic bag to achieve micro-hole punching when the woven plastic bag passes under the needle punching roller 31.

[0027] Furthermore, the feeding mechanism 2 also includes discharge traction rollers 26. Two discharge traction rollers 26 are rotatably arranged between the two side plates of the frame 1, located behind the active feeding wheel 21 and facing each other vertically. The lower discharge traction roller 26 is connected to the fourth motor 27 on the frame 1. When the perforated woven plastic bag is conveyed to the end of the feeding mechanism 2, it enters between the two discharge traction rollers 26. Driven by the fourth motor 27, the lower discharge traction roller 26 cooperates with the upper discharge traction roller 26 to convey the woven plastic bag backward for unloading, ensuring the stability of unloading.

[0028] Furthermore, the side plate of the frame 1 is provided with an adjustment groove 11 extending along the arrangement direction of several driven feeding wheels 22. An adjustment plate 28 located outside the adjustment groove 11 is longitudinally slidably provided on the frame 1. The rotation shaft of the driven feeding wheel 22 passes through the adjustment groove 11 and is rotatably connected to the adjustment plate 28. Several springs 29 located above the adjustment plate 28 and abutting against the adjustment plate 28 are provided on the frame 1. The adjustment plate 28 has a downward sliding tendency under the action of the springs 29, so that the driven feeding wheel 22 has a tendency to drive towards the active feeding wheel 21. This ensures that when the woven plastic bag enters between the active feeding wheel 21 and the driven feeding wheel 22, the driven feeding wheel 22 and the active feeding wheel 21 always clamp the side of the woven plastic bag, ensuring the stability of conveying the woven plastic bag and strengthening the friction in the width direction of the woven plastic bag, ensuring that the woven plastic bag remains unfolded and taut when passing under the needle-punching roller 31, thereby ensuring the stability and quality of the punching process.

[0029] Furthermore, it also includes a cleaning mechanism 4 located between the punching mechanism 3 and the discharge traction roller 26. The cleaning mechanism 4 includes a cleaning roller 41 with several rows of bristles on its circumferential surface. Two cleaning rollers 41 are rotatably disposed between the two side plates of the frame 1 and face downwards. The two cleaning rollers 41 are respectively connected to the fifth motor 42 and the sixth motor 43 disposed on the frame 1. The plastic woven bag that has been punched is conveyed into the space between the two cleaning rollers 41 and comes into contact with the bristles on the cleaning rollers 41. The two cleaning rollers 41, driven by the fifth motor 42 and the sixth motor 43 respectively, rotate and drive the bristles to clean the surface of the plastic woven bag, removing the debris left on the surface of the plastic woven bag during the punching process.

[0030] Furthermore, it also includes a feeding mechanism 5 located in front of the feeding mechanism 2. The feeding mechanism 5 includes a guide plate 51, a feeding conveyor belt 52, and an adjusting plate 53. The guide plate 51 is fixedly mounted on the frame 1 and connected to the feeding traction roller 24. The guide plate 51 has several mounting grooves 511 extending along the conveying direction of the feeding traction roller 24. Several feeding conveyor belts 52 are arranged on the guide plate 51 and are located in several mounting grooves 511. Two adjusting plates 53 are slidably mounted on the side plates of the frame 1 above the guide plate 51, and the adjusting plates 53 are connected to the cylinders 54 mounted on the frame 1. The guide plate 51 is connected to the discharge conveyor belt of the previous forming process. After the plastic woven bag falls onto the guide plate 51, the two adjusting plates 53 are driven by the cylinder 54 to move towards the plastic plate, thereby pushing the plastic woven bag and adjusting its position on the guide plate 51. This aligns the two sides of the plastic woven bag with the active feeding wheels 21 on the two side plates of the frame 1. The feeding conveyor belt 52 drives the plastic woven bag on the guide plate 51 to be conveyed towards the feeding traction roller 24, so that the plastic woven bag passes between the two feeding conveyor rollers. This ensures that the two sides of the plastic woven bag can enter between the active feeding wheel 21 and the driven feeding wheel 22 and be conveyed, thus ensuring the stability during feeding.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
