Description

Technical Field

[0001] This utility model relates to the field of nonwoven packaging bag technology, specifically to a cutting device for nonwoven packaging bags. Background Technology

[0002] Non-woven packaging bags are an environmentally friendly packaging material. They are non-woven fabrics made of oriented or randomly arranged fibers bonded together by physical methods. This material is lightweight, soft, breathable, reusable, and biodegradable. Due to its durability and reusability, non-woven bags are often used as shopping bags to replace disposable plastic bags, helping to reduce plastic waste and protect the environment. The use of non-woven packaging bags aligns with the concept of sustainable development, helps reduce environmental pollution, and is a manifestation of promoting a green lifestyle. With the increasing awareness of environmental protection in society, the application of non-woven packaging bags will become even more widespread.

[0003] A search revealed a utility model patent with publication number CN221623177U, which discloses a cutting device for packaging bag production, relating to the field of packaging bag production technology. This utility model includes an operating table with support plates fixedly connected to both sides of its top. An adjustment mechanism is provided at one end of the opposing surfaces of the two support plates. Adjustment frames are fixedly fitted onto both sides of the outer surface of the support rods. Two connecting rods are connected through both ends of the adjustment frames. Two fixing plates are fixedly connected to one end of the opposing surfaces of the four connecting rods. Anti-slip sleeves are fixedly connected to one end of the opposing surfaces of the two fixing plates. Pull plates are fixedly connected to the ends of the four connecting rods away from the fixing plates, passing through both ends of the adjustment frames. Springs are fitted onto the outer surfaces of the four connecting rods. Cutting blades are fixedly connected to the bottom ends of the two adjustment frames. A collecting mechanism is provided at one end of the operating table. By setting the adjustment mechanism, the position of the cutting blade can be adjusted according to requirements. The collecting mechanism is used to collect the edge material.

[0004] However, the above design still has shortcomings. The design uses an adjustment mechanism to adjust the position of the cutting blade according to needs and an edge collection mechanism to collect the edge material. However, in actual application, after the packaging bag is cut, the broken edge will spring back due to electrostatic adsorption. It is also difficult to manually find the broken edge and continue the work, which leads to a decrease in work efficiency. To address this issue, we propose a cutting device for non-woven packaging bags. Utility Model Content

[0005] The purpose of this invention is to provide a cutting device for non-woven packaging bags to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for non-woven packaging bags, comprising a workbench, an adsorption hole on the upper surface of the workbench, a bellows connected to the lower surface of the workbench, a fan connected to the right side of the bellows, a No. 1 motor connected to the right side of the fan, an air control valve installed on the back of the bellows, an air accumulator connected to the bottom surface of the adsorption hole, the air accumulator connected to the adsorption hole, and an exhaust pipe connected to the left side of the air accumulator and the left side of the bellows.

[0007] The upper surface of the workbench is connected to a support box, and the inner wall of the support box is rotatably connected to a bag outlet shaft.

[0008] The workbench has multiple support legs mounted on its bottom surface and a control panel connected to its front surface.

[0012] The workbench has a support frame connected to its upper surface, and two regulating valves connected to the upper surface of the support frame. Two threaded rods of type 2 are connected to the inner wall of the support frame. The output end of each regulating valve passes through the outer wall of the support frame and is fixedly connected to one end of the threaded rod of type 2. Each threaded rod of type 2 has a connecting block threadedly connected to its outer surface. The two connecting blocks are rotatably connected to a guide roller on their sides that are close to each other.

[0013] The inner wall of the support frame is rotatably connected to a second guide roller, and the front of the support frame is connected to a third motor. The output end of the third motor passes through the outer wall of the support frame and is fixedly connected to one end of the second guide roller.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention uses a motor to drive a fan to generate negative pressure, which is then used to adsorb the cut ends through an adsorption port. Automatic adsorption of the cut ends eliminates the need for manual searching and cleaning, saving time, improving production efficiency, and maintaining production continuity. By adjusting the suction power, different suction levels can be designed for different materials, making the equipment adaptable to various non-woven fabrics and improving its versatility. Furthermore, the automatic adsorption system helps reduce material adhesion caused by static electricity during the cutting process of non-woven fabrics. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This utility model provides a technical solution: a cutting device for non-woven packaging bags, including a workbench 1, an adsorption hole 19 on the upper surface of the workbench 1, a bellows 23 connected to the lower surface of the workbench 1, a fan 17 connected to the right side of the bellows 23, a first motor 14 connected to the right side of the fan 17, an air control valve 15 installed on the back of the bellows 23, an air accumulator 16 connected to the bottom surface of the adsorption hole 19, the air accumulator 16 being connected to the adsorption hole 19, and an exhaust pipe 18 being connected to the left side of the air accumulator 16 and the left side of the bellows 23.

[0023] The upper surface of the workbench 1 is connected to a support box 10, and the inner wall of the support box 10 is rotatably connected to a bag-out shaft 4. The bag-out shaft 4 is fixed on the workbench 1 through the support box 10, which can ensure that the non-woven bag is stably exited during the cutting process and reduce the cutting deviation caused by the movement of the bag.

[0024] The workbench 1 has multiple support legs 2 installed on its bottom surface. The support legs 2 increase the stability of the workbench 1 and ensure that the equipment will not move due to vibration during the entire cutting process, thereby ensuring the accuracy of the cutting. The front of the workbench 1 is connected to a control panel 3.

[0025] The upper surface of the workbench 1 is connected to the edge trimming frame 5, the front of the edge trimming frame 5 is connected to the second motor 6, the inner wall of the edge trimming frame 5 is connected to the first threaded rod 12, the output end of the second motor 6 passes through the outer wall of the edge trimming frame 5 and is fixedly connected to one end of the first threaded rod 12. The connection of the second motor 6 enables the edge trimming process to be automated. The rotation of the second motor 6 drives the first threaded rod 12, thereby controlling the cutting action.

[0026] Among them, the outer surface of the first threaded rod 12 is threaded with a slider 13, and the bottom surface of the slider 13 is connected to a cylinder 26. The cylinder 26 can provide a stable pushing and pulling force. By adjusting the pressure of the cylinder 26, the cutting force can be controlled to adapt to non-woven packaging bags of different materials and thicknesses.

[0027] The output end of the cylinder 26 is connected to a heating block 25, and the front of the heating block 25 is connected to a cutter 22. The heated cutter 22 can cut the non-woven fabric better and reduce the burrs and fluff on the cutting edge. The upper surface of the worktable 1 is connected to a cutting groove 24.

[0028] The upper surface of the workbench 1 is connected to a support frame 9, and the upper surface of the support frame 9 is connected to two regulating valves 7. By combining the regulating valves 7 and the second threaded rods 8, the position of the first guide roller 27 can be precisely adjusted, thereby controlling the feeding speed and tension of the nonwoven material. The inner wall of the support frame 9 is connected to two second threaded rods 8. The output end of each regulating valve 7 passes through the outer wall of the support frame 9 and is fixedly connected to one end of the second threaded rod 8. The outer surface of each second threaded rod 8 is threaded with a connecting block 20. The two connecting blocks 20 are rotatably connected to the first guide roller 27 on their sides that are close to each other.

[0029] The inner wall of the support frame 9 is rotatably connected to the second guide roller 21, and the front of the support frame 9 is connected to the third motor 11. The output end of the third motor 11 passes through the outer wall of the support frame 9 and is fixedly connected to one end of the second guide roller 21. The connection of the third motor 11 enables the second guide roller 21 to rotate automatically, thereby realizing the automatic feeding of non-woven fabric materials.

[0030] Working principle: In operation, the operator first pulls out the packaging bag using the bag-exit shaft 4. Then, the adjustment valve 7 and the second threaded rod 8 work together to adjust the first guide roller 27, thus accommodating packaging bags of different thicknesses. Next, the second motor 6 drives the first threaded rod 12 to rotate, and the slider 13 on the first threaded rod 12 moves horizontally. Then, the cylinder 26 drives the heating block 25 and the cutter 22 to move downwards. Through horizontal movement, the packaging bag is cut. Finally, the third motor 11 drives the second guide roller 21 to advance... The system rotates to automatically feed the non-woven fabric material. At the same time, the No. 1 motor 14 drives the fan 17 to generate negative pressure. The suction is adjusted by the cooperation of the air box 23 and the air control valve 15 to ensure that different suction can be adjusted for different materials. Then, the cut ends are adsorbed onto the adsorption holes 19 through the cooperation of the exhaust pipe 18 and the air accumulator box 16. This avoids the problem of the cut ends being difficult to find due to elasticity and electrostatic adsorption after cutting, which would reduce work efficiency and reduce the tedious operation of manually searching for the cut ends.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
