Description
Technical Field
[0001] The utility model relates to the technical field of circular knife machines, in particular to a circular knife machine for insulating materials which is convenient for buffering and limiting. Background Art
[0002] Circular knife machine is a common equipment in industrial production, mainly used for cutting and processing materials. When working, the circular knife machine cuts, slits, slots, punches and other operations on the material according to the preset specifications and shapes through the relative movement of the rotating knife and the material to meet different production needs. Circular knife machine has the characteristics of high efficiency, precision and continuous processing, so it is widely used in many industries such as printing, packaging, electronics, and automotive interior.
[0003] However, when the existing circular knife machine for insulating materials is processing the insulating materials, the insulating materials are generally die-cut through the circular knife machine by continuous feeding motion. However, when the insulating materials are subjected to the external force of the circular knife machine die-cutting, the movement speed of the insulating materials will change, resulting in an unstable movement state of the insulating materials, thereby affecting the movement stability of the insulating materials on the conveyor belt. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model provides a circular knife machine for insulating materials that is convenient for buffering and limiting. The utility model can solve the problem that, when the insulating material is subjected to the external force of die-cutting by the circular knife machine, the movement speed of the insulating material will change, resulting in an unstable movement state of the insulating material, thereby affecting the moving stability of the insulating material on the conveyor belt. The utility model can buffer and limit the insulating material at the discharge position through a buffer component so that the die-cut material can smoothly leave the processing area, and can also eliminate static electricity on the insulating material to prevent safety hazards.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a circular knife machine for insulating materials that is convenient for buffering and limiting, comprising a circular knife machine body, one side of the circular knife machine body is rotatably connected to a driving screw, the driving screw is connected to a buffer assembly, the buffer assembly includes a limiting shaft, and the buffer assembly is used to buffer the insulating material;
[0006] A driving wheel is arranged inside the main body of the circular knife machine, and a belt is sleeved on the outer surface of the driving wheel. The belt is connected to a tensioning wheel and a driven wheel, and the driven wheel is connected to an anti-static elimination component. The anti-static elimination component includes a reciprocating screw, a slider and a conductive brush. The anti-static elimination component is used to eliminate static electricity accumulated in insulating materials.
[0007] Through the above technical solution, the buffer component can be used to buffer and limit the die-cut insulating material, and the resistance of the insulating material during movement can be increased through the limiting shaft, thereby slowing down its movement speed and achieving buffer limiting. The buffer limiting can further eliminate slight position deviations to ensure the accuracy and consistency of each die-cutting.
[0008] Furthermore, U-shaped blocks are fixedly connected to both ends of the limit shaft, a guide shaft is slidably connected to the lower part of the U-shaped block, the guide shaft is fixedly connected to the circular knife machine body, and the U-shaped block is threadedly connected to the driving screw.
[0009] Through the above technical solution, the driving screw drives the U-shaped block to rise and fall by rotating, and the guide shaft guides and limits the rising and falling of the U-shaped block. The U-shaped block drives the guide shaft to move synchronously. The position of the guide shaft can be adjusted to make it contact with the insulating material. After the guide shaft and the insulating material contact each other, the friction force on the insulating material during movement will increase, thereby slowing down the movement speed of the insulating material and achieving the purpose of buffering and limiting.
[0010] Furthermore, a support plate is fixedly connected to the inner side of the U-shaped block, the reciprocating screw rod passes through the support plate, and the reciprocating screw rod and the driven wheel are connected in a fixed manner.
[0011] Through the above technical solution, the support plate can support the reciprocating screw rod, and under the action of the tensioning wheel, after the position of the driven wheel is adjusted, the driving wheel can still transmit power to the driven wheel through the belt.
[0012] Furthermore, the reciprocating screw rod is connected to the slider by a threaded connection, the upper end of the support plate is fixedly connected to a limit block, and the slider is connected to the limit block by a sliding connection.
[0013] Through the above technical solution, the reciprocating screw drives the slider to move back and forth by rotating, and the slider drives the conductive brush to move synchronously. When the insulating material passes under the conductive brush, the conductive brush can conduct static electricity to the ground, thereby eliminating static electricity.
[0014] Furthermore, the slider is connected to the conductive brush in a fixed manner, the upper end of the slider is connected to a first connecting wire, and the end of the first connecting wire is connected to a second connecting wire.
[0015] Through the above technical solution, the second connecting line is connected to the grounding system, and the conductive brush conducts static electricity to the ground through the first connecting line and the second connecting line connected by the slider.
[0016] Furthermore, a support block is fixedly connected inside the limiting block, and a slot is provided at the lower end of the support block. The width of the slot is greater than the diameter of the first connecting line, and the width of the slot is less than the diameter of the second connecting line.
[0017] Through the above technical solution, since the width of the slot is greater than the diameter of the first connecting wire, the first connecting wire can pass through the slot and move inside the slot. Since the width of the slot is smaller than the diameter of the second connecting wire, the second connecting wire cannot pass through the slot, thereby ensuring that the second connecting wire is stable inside the support block.
[0018] Furthermore, a collar is sleeved on the outer surface of the second connecting line, a connecting block is fixedly connected to the outer surface of the collar, and the connecting block is connected to the supporting block in a sliding manner.
[0019] Through the above technical solution, when the slider is performing left-right reciprocating motion, the sleeve ring connected to the connecting block will drive the second connecting line to move inside the supporting block.
[0020] Furthermore, a spring is connected to one side of the connecting block, and the other end of the spring is fixedly connected to the supporting block.
[0021] Through the above technical solution, the connecting block forms a telescopic structure inside the supporting block through the spring, thereby facilitating the second connecting line to perform reciprocating motion inside the supporting block.
[0022] Compared with the prior art, the utility model provides a circular knife machine for insulating materials that is convenient for buffering and limiting, and has the following beneficial effects:
[0023] In the utility model, the guide shaft can be brought into contact with the insulating material by adjusting its position. After the guide shaft and the insulating material come into contact with each other, the friction force on the insulating material during movement will increase, thereby slowing down the movement speed of the insulating material and achieving the purpose of buffering and limiting. In addition, slight position deviations can be further eliminated through buffering and limiting, thereby ensuring the accuracy and consistency of each die-cutting. In this process, the slider drives the conductive brush to move back and forth left and right. When the insulating material passes under the conductive brush, the conductive brush can conduct static electricity to the ground, thereby eliminating static electricity.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0032] See also Figure 1-Figure 6 The utility model provides a technical solution: a circular knife machine for insulating materials that is convenient for buffering and limiting, comprising a circular knife machine body 1, one side of the circular knife machine body 1 is rotatably connected with a driving screw 2, the driving screw 2 is connected with a buffer assembly, the buffer assembly comprises a limiting shaft 5, the buffer assembly is used to buffer the insulating material, both ends of the limiting shaft 5 are fixedly connected with U-shaped blocks 3, the lower part of the U-shaped block 3 is slidably connected with a guide shaft 4, the guide shaft 4 is connected to the circular knife machine body 1 in a fixed connection, and the U-shaped block 3 is connected to the driving screw 2 in a threaded connection;
[0033] The principle of buffering and limiting the insulating material is: first, rotate the driving screw 2, and the driving screw 2 will drive the U-shaped block 3 to rise and fall through rotation, and the guide shaft 4 guides and limits the rise and fall of the U-shaped block 3, and the U-shaped block 3 drives the guide shaft 4 to move synchronously. By adjusting the position of the guide shaft 4, it can be made to contact with the insulating material. After the guide shaft 4 and the insulating material contact each other, the friction force on the insulating material during movement will increase, thereby slowing down the movement speed of the insulating material and achieving the purpose of buffering and limiting. In addition, through buffering and limiting, small position deviations can be further eliminated to ensure the accuracy and consistency of each die-cutting.
[0034] See also Figure 1-Figure 3A driving wheel 6 is arranged inside the circular knife machine body 1, and a belt 7 is sleeved on the outer surface of the driving wheel 6. The belt 7 is connected to a tensioning wheel 8 and a driven wheel 9. A support plate 10 is fixedly connected to the inner side of the U-shaped block 3. A reciprocating screw rod 11 passes through the support plate 10, and the reciprocating screw rod 11 is connected to the driven wheel 9 in a fixed connection.
[0035] The function of the tensioning wheel 8 is that the support plate 10 can support the reciprocating screw rod 11, and under the action of the tensioning wheel 8, after the position of the driven wheel 9 is adjusted, the driving wheel 6 can still transmit power to the driven wheel 9 through the belt 7.
[0036] See also Figure 1-Figure 6 The driven wheel 9 is connected to an electrostatic elimination component, which includes a reciprocating screw 11, a slider 12 and a conductive brush 13. The electrostatic elimination component is used to eliminate static electricity accumulated in insulating materials. The reciprocating screw 11 and the slider 12 are connected by a threaded connection. The upper end of the support plate 10 is fixedly connected to a limit block 14, and the slider 12 and the limit block 14 are connected by a sliding connection.
[0037] The principle of static electricity elimination for insulating materials is as follows: the driving wheel 6 drives the driven wheel 9 to rotate through the belt 7, the driven wheel 9 drives the reciprocating screw 11 to rotate, the reciprocating screw 11 drives the slider 12 to reciprocate left and right through rotation, the slider 12 drives the conductive brush 13 to move synchronously, and when the insulating material passes under the conductive brush 13, the conductive brush 13 can conduct the static electricity to the ground, thereby eliminating the static electricity.
[0038] See also Figure 1-Figure 6 The slider 12 is connected to the conductive brush 13 in a fixed connection manner. The upper end of the slider 12 is connected to a first connecting wire 15, and the end of the first connecting wire 15 is connected to a second connecting wire 16. The inside of the limit block 14 is fixedly connected to a support block 20, and a notch 21 is provided at the lower end of the support block 20.

The outer surface of the second connecting wire 16 is sleeved with a collar 17, and the outer surface of the collar 17 is fixedly connected to a connecting block 18. The connecting block 18 is connected to the supporting block 20 in a sliding connection manner. A spring 19 is connected to one side of the connecting block 18, and the other end of the spring 19 is fixedly connected to the supporting block 20.
[0039] The principle of grounding the conductive brush 13 is as follows: since the width of the slot 21 is greater than the diameter of the first connecting wire 15, the first connecting wire 15 can pass through the slot 21 and move inside the slot 21. Since the width of the slot 21 is less than the diameter of the second connecting wire 16, the second connecting wire 16 cannot pass through the slot 21, thereby ensuring that the second connecting wire 16 is stable inside the support block 20, and the connecting block 18 forms a telescopic structure inside the support block 20 through the spring 19. When the slider 12 drives the first connecting wire 15 and the second connecting wire 16 to reciprocate left and right, the second connecting wire 16 will slide inside the support block 20, which is beneficial to avoid the second connecting wire 16 from affecting the buffer component and the static elimination component during the movement, and the second connecting wire 16 is connected to the grounding system, and the conductive brush 13 conducts static electricity to the ground through the first connecting wire 15 and the second connecting wire 16 connected by the slider 12.
