Description

Technical Field

[0001] This utility model belongs to the field of plastic bag cutting, and in particular relates to a cutting device for the production of biodegradable and environmentally friendly plastic bags. Background Technology

[0002] For example, Chinese Patent (Publication No.: CN220994682U) discloses a cutting machine for producing biodegradable and environmentally friendly plastic bags, including a base, a cylinder fixedly mounted on the base, a mounting plate fixedly connected to the cylinder, a mounting seat fixedly connected to the mounting plate, a sliding rod slidably connected inside the mounting seat, a cutting blade fixedly connected to one end of the sliding rod, a damping block fixedly connected to the sliding rod, a damping block slidably connected inside the mounting seat, a spring installed inside the mounting seat, an air inlet on the mounting seat, and a guide frame fixedly connected to the base. This utility model, by incorporating components such as the mounting seat, damping block, and air inlet, can buffer the cutting blade during use, effectively reducing the impact force on the cutting blade and providing effective protection. This solves the problem of cutting blades lacking a buffer structure and easily damaged during use.

[0003] However, the above-mentioned cutting machine requires separate operation of the clamping mechanism to position and fix the plastic bag before the cutting blade can cut the plastic bag. After the plastic bag is cut, the clamping structure needs to be controlled separately to release the plastic bag, which is cumbersome. In addition, the plastic bag is only positioned and fixed on one side, which is not effective. During the cutting process, the unfixed side of the plastic bag is prone to slippage, which affects the cutting quality.

[0004] Therefore, a cutting device for the production of biodegradable and environmentally friendly plastic bags is needed to solve the above problems. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0031] Example 1

[0032] like Figures 1-3 As shown, this utility model embodiment provides a cutting device for the production of biodegradable and environmentally friendly plastic bags, including a support component 1. The support component 1 includes a workbench 11, a first support frame 12, and a second support frame 13. The workbench 11 serves as the foundation of the device and provides an installation platform. The groove 15 provides a buffer space for the cutting blade 22 to prevent the blade from directly contacting the workbench during cutting and causing damage. There are two second support frames 13. The first support frame 12 and the two second support frames 13 are all fixed to the top of the workbench 11. The surface of the workbench 11 has a groove 15. The front and back of the first support frame 12 both have through slots 14.

[0033] The first support frame 12 is equipped with a cutting assembly 2, which supports the cutting assembly 2 and ensures the stability of the vertical movement of the cutting blade 22. The cutting assembly 2 includes a first electric push rod 21, a cutting blade 22, a guide rod 23, and a top rod 24. The output end of the first electric push rod 21 is connected to the cutting blade 22. The cutting blade 22 directly contacts the plastic bag and completes the cutting. The blade is adapted to the groove 15 and can be inserted into the groove after cutting to avoid wear.

[0034] The guide rod 23 passes through the first support frame 12 and is fixed to the cutting blade 22. The guide rod 23 restricts the movement trajectory of the cutting blade 22 to prevent deviation during cutting and improve cutting accuracy. The top rod 24 is fixed to the top of the cutting blade 22. The top rod 24 moves synchronously with the cutting blade 22. By contacting / disconnecting with the first control button 6, the clamping / releasing action of the fixing component 4 is triggered.

[0035] The second support frame 13 is equipped with a conveying assembly 3, which supports the conveying assembly 3 and provides a pivot point for the rotating roller 31. The conveying assembly 3 includes a rotating roller 31, a second electric push rod 32, a limiting groove 33, and a limiting plate 34. The rotating roller 31 is rotatably connected to the second support frame 13. The rotating roller 31 is driven to rotate by a motor and moves the plastic bag through friction to achieve automatic feeding and unloading. The two sets of rotating rollers are responsible for material transfer before and after cutting. One end of the rotating roller 31 is connected to a motor, and the second electric push rod 32 is connected inside the rotating roller 31. Both ends of the second electric push rod 32 are connected to the limiting plate 34. The limiting groove 33 is opened on the surface of the rotating roller 31. The second electric push rod 32 adjusts the distance between the two limiting plates 34 to adapt to plastic bags of different widths and ensure that the material is flat during conveying.

[0036] A fixing component 4 is installed on the workbench 11. The fixing component 4 includes a third electric push rod 41, a limit rod 42 and a pressure plate 43. The output end of the third electric push rod 41 is connected to the pressure plate 43. The third electric push rod 41 drives the pressure plate 43 to move up and down, thereby clamping and releasing the plastic bag.

[0037] The limiting rod 42 passes through the workbench 11 and is connected to the pressure plate 43. The limiting rod 42 restricts the movement direction of the pressure plate 43 to ensure uniform pressure when clamping. The pressure plate 43 increases the friction with the plastic bag through the anti-slip texture on the bottom surface. The two sets of pressure plates clamp the material from both sides of the groove 15 to prevent slippage during cutting.

[0038] The first support frame 12 is equipped with a controller 5 and a first control button 6, and the worktable 11 is equipped with a second control button 8. The front and back of the cutting blade 22 are both fixed with pressure rods 7. The controller 5 is electrically connected to the first electric push rod 21, the second electric push rod 32, the third electric push rod 41, the motor, the first control button 6 and the second control button 8 respectively. The controller 5 receives the signals from each button and coordinates the operation of each electric push rod and the motor to achieve automated linkage.

[0039] The push rod 24 corresponds to the position of the first control button 6. When the cutting blade 22 descends, the push rod 24 disengages from the first control button 6, triggering the extension of the third electric push rod 41. The first control button 6 cooperates with the push rod 24 to control the extension and retraction state of the third electric push rod 41.

[0040] The cutting blade 22 is adapted to the groove 15. After cutting, the cutting blade 22 can extend into the groove 15. The pressure rod 7 corresponds to the position of the second control button 8. When the cutting blade 22 extends into the groove 15, the pressure rod 7 presses the second control button 8. The second control button 8 cooperates with the pressure rod 7 to trigger the unloading and feeding actions after cutting. The pressure rod 7 moves with the cutting blade 22. After cutting is completed, the second control button 8 is pressed to transmit a signal to the controller.

[0041] Two rotating rollers 31 are symmetrically distributed on both sides of the groove 15. The limiting plate 34 is slidably connected in the limiting groove 33. The limiting groove 33 and the limiting plate 34 cooperate to form a guide channel to prevent the plastic bag from shifting during the conveying process and ensure accurate cutting position.

[0042] The fixing component 4 is provided in two sets, located on both sides of the groove 15 respectively;

[0043] The guide rod 23 is slidably connected to the first support frame 12, and the limiting rod 42 is slidably connected to the worktable 11.

[0044] In this embodiment, the controller 5 controls the first electric push rod 21 to drive the cutting blade 22 down, the top rod 24 disengages from the first control button 6, triggering the extension of the third electric push rod 41, and the pressure plate 43 descends to clamp the plastic bag; then the first electric push rod 21 drives the cutting blade 22 down to cut, after cutting the plastic bag the cutting blade 22 extends into the groove 15, the pressure rod 7 presses the second control button 8, the controller 5 then controls the third electric push rod 41 to retract and release the material and the motor to start, the rotating roller 31 removes the cut plastic bag and conveys new material to the cutting position, and repeats the above process.

[0045] Example 2

[0046] The difference between this embodiment and embodiment 1 is that: the surface of the rotating roller 31 is covered with a rubber layer to increase the friction with the plastic bag; and a silicone pad is pasted on the bottom surface of the limiting plate 34 to avoid damaging the surface of the biodegradable plastic bag.

[0047] The working principle of this utility model:

[0048] Initial state: the cutting blade 22 is in the high position, the third electric push rod 41 is in the retracted state, and the pressure plate 43 is raised.

[0049] Feeding and positioning: Uncut plastic bags are conveyed to the top of the groove 15 by the rotating roller 31, and the second electric push rod 32 drives the two limit plates 34 to move closer to each other to limit the plastic bags of different widths;

[0050] Clamping and fixing: The first electric push rod 21 drives the cutting blade 22 to descend, the top rod 24 disengages from the first control button 6, and the controller 5 receives the signal and controls the third electric push rod 41 to extend, and the pressure plate 43 descends to clamp the two sides of the plastic bag.

[0051] Cutting action: The first electric push rod 21 drives the cutting blade 22 to descend, the blade contacts the plastic bag and completes the cut, and then the cutting blade 22 extends into the groove 15;

[0052] Unloading and Cycle: During the descent of the cutting blade 22, the pressure rod 7 presses the second control button 8, and the controller 5 controls the third electric push rod 41 to retract and release the material. At the same time, the motor is started to drive the rotating roller 31 to rotate, remove the cut plastic bag, and transport the new material to the cutting position. The cutting blade 22 rises and resets, and enters the next cycle.

[0053] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0054] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
