Abstract
Description
Technical Field
[0001] This utility model relates to the field of polymer packaging material processing technology, specifically to a cutting device for processing polymer packaging materials. Background Technology
[0002] Polymer materials are materials based on polymer compounds. They are materials composed of compounds with relatively high molecular weights, including rubber, plastics, fibers, coatings, adhesives, and polymer-based composite materials. Polymers are a form of life, and all living organisms can be regarded as collections of polymers.
[0003] A search revealed an existing patent (publication number: CN215749509U) disclosing a cutting device for polymer packaging materials, relating to the field of cutting technology. The device includes: a main body; and a rotating mechanism connected to one end of the main body. The rotating mechanism includes a support seat and a tension roller, with the support seat located on the inner wall of the main body. This invention utilizes a moving mechanism. When an electric push rod moves and pushes a second cutter holder until its gear meshes with a second gear, the second cutter holder moves downwards, causing the first cutter holder to move upwards via the second gear. At this point, both the second and first cutter holders are in contact with the polymer packaging material, thus achieving the function of cutting the polymer packaging material. After cutting, the electric push rod moves upwards, causing the second cutter holder to move upwards. The upward movement of the second cutter holder causes the second gear to reverse, and the rotation of the second gear causes the first cutter holder to move downwards, thus achieving the function of storing the first cutter holder and preventing the first cutter holder from constantly being in contact with the polymer packaging material.
[0004] However, in the above solution, the cutting blade used for cutting is not easy to remove from the equipment during use. When the cutting blade wears down, it will affect the cutting work and cause the material to be unable to be cut.
[0005] In view of this, the present invention proposes a cutting device for processing polymer packaging materials. Utility Model Content
[0006] This utility model proposes a cutting device for processing polymer packaging materials, which solves the problem that in the previous cutting device, the cutting blade used for cutting was not easy to remove from the equipment, and when the cutting blade was worn, it would affect the cutting work and cause the material to be unable to be cut.
[0007] The technical solution of this utility model is as follows: A cutting device for processing polymer packaging materials includes a base, a conveyor belt body placed on the top of the base, an installation plate fixedly connected to the base at one end of the conveyor belt body, an electric cylinder fixedly connected to the bottom of the installation plate, a connecting seat fixedly connected to the output end of the electric cylinder, a lead screw threadedly connected to the top of the connecting seat, a transmission plate rotatably connected to the bottom of the lead screw and slidably connected to the inside of the connecting seat, a transmission block fixedly connected to the tail of the transmission plate, a spring fixedly connected to the surface of the connecting seat, a force-receiving block that fits against the transmission block fixedly at the tail of the spring, an insert plate penetrating into the inside of the connecting seat fixedly connected to one end of the force-receiving block, and a cutting blade embedded in the inside of the connecting seat slidably connected to the surface of the insert plate.
[0008] Preferably, a motor is fixedly connected to the top of the mounting plate, a bidirectional screw is fixedly connected to the output end of the motor, two sets of sliders are threadedly connected to the surface of the bidirectional screw and slidably connected to the mounting plate, movable plates are rotatably connected to the inner sidewalls of the two sets of sliders, and fixed plates located above the conveyor belt body are rotatably connected to the surfaces of the two sets of movable plates. A telescopic plate is fixedly connected to the top of the fixed plate, and a connecting port located below the cutting blade is provided on the surface of the fixed plate.
[0009] Preferably, the transmission plate forms a sliding structure inside the connecting seat via a lead screw.
[0010] Preferably, the contact surfaces of the transmission block and the force-bearing block are both inclined, and the spring forms a telescopic structure through the transmission block.
[0011] Preferably, the insert plate is in close contact with the cutting blade, and the cutting blade forms an engaging structure inside the connecting seat through the insert plate.
[0012] Preferably, the connection points between the movable plate and the slider and the fixed plate are all located at their own endpoints, and the fixed plate is inclined.
[0013] Preferably, the fixed plate and the conveyor belt body are arranged parallel to each other, and the telescopic plate consists of two sets of vertical plates that slide and fit together.
[0014] Preferably, the connector is located directly below the cutting blade, and the size of the connector is larger than that of the cutting blade.
[0015] The working principle and beneficial effects of this utility model are as follows:
[0016] In this invention, a fixed plate is set up, and the motor controls the bidirectional screw to rotate. The two sets of sliders will move away from each other and apply a pushing force to the two sets of movable plates, causing them to rotate to the side. During the rotation, a downward pushing force is applied to the fixed plate. Under the limiting action of the telescopic plate, the fixed plate will move horizontally downward and fit against the material, thereby preventing the material from bending upward during movement. Then, the material is cut by a cutting blade using an electric cylinder.
[0017] In this invention, a connecting port is provided to prevent the cutting blade from being blocked by the fixing plate when it descends. When the cutting blade needs to be replaced, the lead screw can be rotated to control the transmission block to slide upward inside the connecting seat, thereby driving the transmission block to rise. At this time, the transmission block no longer applies force to the force-bearing block. Under the action of the spring, it will quickly apply a lateral pushing force to the force-bearing block and control the fixing plate to slide out of the cutting blade. At this time, the cutting blade loses the locking force of the fixing plate and can be quickly removed from the inside of the connecting seat, thus achieving the purpose of disassembling the cutting blade.

Detailed Implementation
[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. 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 of ordinary skill in the art without creative effort are within the scope of protection of this utility model. Example 1
[0026] A preferred embodiment of the cutting device for processing polymer packaging materials provided by this utility model is, for example... Figures 1 to 5 As shown: A cutting device for processing polymer packaging materials includes a base 1, a conveyor belt body 2 placed on top of the base 1, an installation plate 3 fixedly connected to the base 1 at one end of the conveyor belt body 2, an electric cylinder 4 fixedly connected to the bottom of the installation plate 3, a connecting seat 5 fixedly connected to the output end of the electric cylinder 4, a lead screw 6 threadedly connected to the top of the connecting seat 5, a transmission plate 7 rotatably connected to the bottom of the lead screw 6 and slidably connected to the inside of the connecting seat 5, a transmission block 8 fixedly connected to the tail of the transmission plate 7, a spring 12 fixedly connected to the surface of the connecting seat 5, a force-receiving block 9 that fits against the transmission block 8 fixedly to the tail of the spring 12, an insert plate 10 that penetrates into the inside of the connecting seat 5 fixedly connected to one end of the force-receiving block 9, and a cutting blade 11 embedded in the inside of the connecting seat 5 slidably connected to the surface of the insert plate 10.
[0027] In this embodiment, the transmission plate 7 forms a sliding structure inside the connecting seat 5 through the lead screw 6. The lead screw 6 can be rotated to control the transmission block 8 to slide upward inside the connecting seat 5, thereby applying power to the movement of the transmission block 8.
[0028] In this embodiment, the contact surfaces of the transmission block 8 and the force-receiving block 9 are both set as inclined surfaces. The spring 12 forms a telescopic structure through the transmission block 8. When the transmission block 8 rises, it no longer applies force to the force-receiving block 9. Under the action of the spring 12, it will quickly apply a lateral pushing force to the force-receiving block 9 and control the fixing plate 17 to slide out of the interior of the cutting blade 11.
[0029] In this embodiment, the insert plate 10 and the cutting blade 11 are closely fitted together. The cutting blade 11 forms a locking structure inside the connecting seat 5 through the insert plate 10. When the insert plate 10 is inserted into the inside of the cutting blade 11, the cutting blade 11 can be quickly fixed. Example 2
[0030] Based on Example 1, a preferred embodiment of the cutting device for processing polymer packaging materials provided by this utility model is as follows: Figures 1 to 5As shown: A motor 13 is fixedly connected to the top of the mounting plate 3. A bidirectional screw 14 is fixedly connected to the output end of the motor 13. Two sets of sliders 15 are threadedly connected to the surface of the bidirectional screw 14 and are slidably connected to the mounting plate 3. Movable plates 16 are rotatably connected to the inner side walls of the two sets of sliders 15. Fixed plates 17 located above the conveyor belt body 2 are rotatably connected to the surface of the two sets of movable plates 16. A telescopic plate 18 is fixedly connected to the top of the fixed plate 17. A connecting port 19 located below the cutting blade 11 is provided on the surface of the fixed plate 17.
[0031] In this embodiment, the connection points of the movable plate 16 with the slider 15 and the fixed plate 17 are all located at their own endpoints. The fixed plate 17 is inclined. The motor 13 controls the bidirectional screw 14 to rotate, and the two sets of sliders 15 will move away from each other, thereby applying a pushing force to the two sets of movable plates 16, causing them to rotate to the side.
[0032] In this embodiment, the fixed plate 17 and the conveyor belt body 2 are arranged parallel to each other, and the telescopic plate 18 consists of two sets of vertical plates that slide together. When the movable plate 16 moves, it will exert a downward thrust on the fixed plate 17. Under the limiting action of the telescopic plate 18, the fixed plate 17 will move horizontally downward and fit against the material, thereby avoiding the problem of the material bending upward during movement.
[0033] The working principle and usage process of this utility model are as follows: First, the packaging material to be cut is placed on the conveyor belt body 2 for transmission. The motor 13 can be turned on to control the bidirectional screw 14 to rotate. The two sets of sliders 15 will move away from each other and apply a pushing force to the two sets of movable plates 16, causing them to rotate to the side. During the rotation, a downward pushing force is applied to the fixed plate 17. Under the limiting action of the telescopic plate 18, the fixed plate 17 will move horizontally downward and fit against the material, thereby preventing the material from bending upward during movement. Then, the material is cut by the cutting blade 11 through the electric cylinder 4.
[0034] By setting the connecting port 19, the connecting port 19 can prevent the fixed plate 17 from blocking the cutting blade 11 when it descends, thus preventing the cutting blade 11 from descending. When the cutting blade 11 needs to be replaced, the lead screw 6 can be rotated to make it control the transmission block 8 to slide upward inside the connecting seat 5, and thus drive the transmission block 8 to rise. At this time, the transmission block 8 no longer applies force to the force block 9. Under the action of the spring 12, it will quickly apply a lateral pushing force to the force block 9 and control the fixed plate 17 to slide out of the inside of the cutting blade 11. At this time, the cutting blade 11 loses the locking force of the fixed plate 17 and can be quickly taken out from the inside of the connecting seat 5, thus achieving the purpose of disassembling the cutting blade 11.
[0035] The above are merely preferred embodiments of the present utility model and are 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 shall be included within the protection scope of the present utility model.
