Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of die-cutting devices, in particular to an asynchronous die-cutting device for silicone die-cutting parts. Background Technique
[0002] The basic principle of die-cutting is to use a die and process raw materials into a specific shape through a die-cutting machine. This process is not limited to metal materials, but also includes the die-forming processing of non-metal materials such as paper, film, tape, foam, silicone rubber and other polymer materials.
[0003] During the production process of copper foil, it needs to be compounded with other materials to form a specific hierarchical structure, and then die-cut after compounding to form the required shape.
[0004] During the working process of the die-cutting device, the die-cutting knife reciprocates up and down. During the downward movement of the die-cutting knife, it will push the air flow downward. The pushed air flow can only flow horizontally towards the outside of the die-cutting knife. Since the copper foil itself is relatively thin and light, the horizontal air flow generated during the movement of the die-cutting knife is very likely to blow the copper foil, resulting in the displacement of the copper foil position, and further affecting the die-cutting accuracy. Content of the Utility Model
[0005] The purpose of the utility model is to provide an asynchronous die-cutting device for silicone die-cutting parts. By sucking the air flow into the cavity, the air flow between the two mounting blocks flows vertically, avoiding the generation of horizontal air flow interference with the copper foil, and further improving the accuracy of the copper foil during die-cutting.
[0006] In order to achieve the above purpose, the utility model provides the following technical solution: an asynchronous die-cutting device for silicone die-cutting parts, used for die-cutting the PET silicone protective film of copper foil products, including a frame. Two die-cutting components are arranged up and down at the top of the frame. The die-cutting component includes a mounting block, and two cavities are opened inside the lower mounting block;
[0007] A gas guide net is arranged at the opening at the top of the cavity. A movable plate is arranged inside the cavity. The outer end of the movable plate is in contact with the inner wall of the cavity. Two guide rods are fixedly arranged at the top of the movable plate. The top ends of the guide rods penetrate through the gas guide net and are fixedly connected to the top mounting block;
[0008] An air guide groove communicated with the inside of the cavity is opened at the bottom end of the lower mounting block.
[0009] Further, two air guide pipes are fixedly arranged at the top of the movable plate, and one-way valves are fixedly arranged on the air guide pipes, so that air can only flow from the top to the bottom of the movable plate.
[0010] Further, a plurality of cushion blocks are fixedly arranged at the bottom end of the lower mounting block. The bottom ends of the cushion blocks are connected to the top of the frame by bolts, separating a certain space between the lower mounting block and the frame.
[0011] Further, two hydraulic cylinders are provided on both sides of the upper mounting block. The bottom end of the hydraulic cylinder is fixedly connected to the top end of the frame, and the top end of the hydraulic cylinder is fixedly connected to the upper mounting block. The upper mounting block is driven to reciprocate up and down by the telescopic movement of the hydraulic cylinder.
[0012] Further, mounting grooves are formed at both ends of the mounting block. Driving rollers are provided on the inner wall of the mounting groove through rotating shafts, and the two driving rollers are connected by a belt. The driving rollers can drive the belt to move when they rotate;
[0013] A plurality of die-cutting plates are fixedly provided at the outer end of the belt. The die-cutting plates can move synchronously with the belt. A plurality of die-cutting knives are fixedly provided on the die-cutting plates of the upper mounting block, and a plurality of grooves corresponding to the die-cutting knives one by one are formed on the die-cutting plates of the lower mounting block. When the die-cutting knives move downward and are inserted into the corresponding die-cutting knives, corresponding shapes are die-cut on the material.
[0014] Further, a motor compartment is formed on one side of the mounting block. A motor for driving the driving roller to rotate is provided inside the motor compartment. The open end of the motor compartment is provided with an end cover through bolts. The motor compartment can be opened by removing the end cover, so as to repair the motor.
[0015] In the above technical solution, the technical effects and advantages provided by the present utility model are as follows:
[0016] The upper mounting block drives the movable plate to move inside the cavity. When the upper mounting block pushes the air flow downward, the air flow is sucked into the cavity. Therefore, the air flow between the two mounting blocks flows vertically, avoiding the generation of lateral air flow interference with the copper foil, and thus improving the accuracy of the copper foil during die-cutting.

[0025] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0026] The present utility model provides a silicone die-cutting part asynchronous die-cutting device as shown in Figures 1-5 Figure, including a frame 1, two die-cutting assemblies 2 are arranged up and down at the top of the frame 1, the die-cutting assembly 2 includes a mounting block 201, and two cavities 12 are opened inside the lower mounting block 201;
[0027] An air guide net 9 is arranged at the opening at the top of the cavity 12, a movable plate 10 is arranged inside the cavity 12, the outer end of the movable plate 10 is in contact with the inner wall of the cavity 12, two guide rods 8 are fixedly arranged at the top of the movable plate 10, and the top ends of the guide rods 8 penetrate through the air guide net 9 and are fixedly connected to the upper mounting block 201;
[0028] An air guide groove 11 communicating with the inside of the cavity 12 is opened at the bottom end of the lower mounting block 201. When the movable plate 10 moves downward, the original air inside the cavity 12 is discharged outward through the air guide groove 11.
[0029] The lower mounting block 201 is fixedly connected to the frame 1, and the upper mounting block 201 can move up and down reciprocally for die-cutting. During die-cutting, the copper foil compounded with the PET silicone protective film is located between the two mounting blocks 201 and moves horizontally. When the upper mounting block 201 moves downward, the guide rod 8 connected to the bottom end thereof moves downward synchronously with it. The guide rod 8 moves downward and pushes the movable plate 10 to move downward inside the cavity 12. During the downward movement, negative pressure is generated inside the cavity 12, and the negative pressure sucks the airflow pushed by the upper mounting block 201 downward through the air guide net 9 into the cavity 12. In this way, during the downward movement of the upper mounting block 201, the airflow between the two mounting blocks 201 flows vertically downward, avoiding the generation of lateral airflow interference to the copper foil, and thus improving the accuracy of the copper foil during die-cutting.
[0030] When the upper mounting block 201 moves upward, it is necessary to prevent the air flow inside the cavity 12 from flowing upward. As Figure 2 , 5 shown, two air guide pipes are fixedly arranged at the top end of the movable plate 10, and one-way valves are fixedly arranged on the air guide pipes, so that air can only flow from the top to the bottom of the movable plate 10.
[0031] A plurality of cushion blocks are fixedly arranged at the bottom end of the lower mounting block 201, and the bottom ends of the cushion blocks are bolted to the top end of the frame 1, separating a certain space between the lower mounting block 201 and the frame 1, which helps the air flow between the mounting block 201 and the frame 1.
[0032] Two hydraulic cylinders 5 are arranged on both sides of the upper mounting block 201. The bottom end of the hydraulic cylinder 5 is fixedly connected to the top end of the frame 1, and the top end of the hydraulic cylinder 5 is fixedly connected to the upper mounting block 201. The upper mounting block 201 is driven to move up and down reciprocally by the telescopic movement of the hydraulic cylinder 5.
[0033] When the upper mounting block 201 moves upward, the movable plate 10 is driven to move upward by the guide rod 8. At this time, the air above the movable plate 10 can flow to the bottom of the movable plate 10 through the air guide pipe, balancing the air pressure on both sides of the movable plate 10. At the same time, it can prevent the air inside the cavity 12 from being pushed and quickly gushing upward through the air guide net 9 during the upward movement of the movable plate 10. The hydraulic cylinder 5 connected to the upper mounting block 201 controls the up and down reciprocating movement of the upper mounting block 201 through its telescopic movement.
[0034] During the movement of the mounting block 201, the copper foil compounded with the PET silicone protective film is die-cut. As Figures 2-5 shown, mounting grooves 202 are formed at both ends of the mounting block 201, and driving rollers 203 are arranged on the inner walls of the mounting grooves 202 through rotating shafts. The two driving rollers 203 are connected by a belt, and the rotation of the driving roller 203 can drive the belt to move;
[0035] A plurality of die-cutting plates 3 are fixedly arranged at the outer end of the belt. The die-cutting plates 3 can move synchronously with the belt. A plurality of die-cutting knives 4 are fixedly arranged on the die-cutting plates 3 of the upper mounting block 201, and a plurality of grooves 7 corresponding to the die-cutting knives 4 one by one are formed on the die-cutting plates 3 of the lower mounting block 201. The die-cutting knives 4 move downward and are embedded into the corresponding die-cutting knives 4, thereby die-cutting corresponding shapes on the material.
[0036] A motor compartment 14 is formed on one side of the mounting block 201. A motor 13 for driving the driving roller 203 to rotate is arranged inside the motor compartment 14. An end cover 6 is arranged at the opening end of the motor compartment 14 through bolts. Removing the end cover 6 can open the motor compartment 14, thereby performing maintenance on the motor 13.
[0037] The die-cutting knives 4 fixed on the upper mounting block 201 correspond to and are aligned with the grooves 7 on the lower mounting block 201 one by one. The copper foil is located between the upper and lower mounting blocks 201. When the upper mounting block 201 moves downward, the die-cutting knives 4 move downward synchronously and stamp on the copper foil. Subsequently, the die-cutting knives 4 cut out holes of corresponding shapes on the copper foil. After die-cutting, the die-cutting knives 4 move downward into the corresponding grooves 7. The grooves 7 can prevent the die-cutting knives 4 from contacting and being damaged by the lower die-cutting plate 3 during the downward movement;
[0038] The motor 13 located inside the motor compartment 14 can drive the driving roller 203 to rotate and move the belt, thereby driving the positions of the die-cutting knives 4 and the grooves 7 to move, so as to enable the die-cutting knives 4 and the grooves 7 to adjust their positions and perform die-cutting work intermittently in turn, avoiding excessive wear of the die-cutting knives 4 and the grooves 7 due to long-term continuous work. At the same time, it is also possible to maintain and clean the die-cutting knives 4 and the grooves 7 without affecting the die-cutting work.
[0039] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
