Description

Technical Field

[0001] The utility model relates to the field of calendering devices, in particular to a calendering device used for producing graphite grounding wires. Background Art

[0002] Graphite grounding wire is a kind of grounding wire used to protect power system equipment. The grounding system is an important part of the power system. Its main function is to connect the metal casing to the earth to ensure the reliable operation of the equipment under normal conditions. The graphite grounding wire uses the resonance effect generated after grounding to reduce the grounding potential, thereby protecting equipment and personnel from electric shock and ensuring the reliability and stability of the power system.

[0003] The calendering device is a device that allows the material to pass through a series of heated roller gaps, where it is squeezed and stretched, reducing the material thickness and increasing the surface area, thereby improving the material properties or making the desired product. In rubber processing, the calendering device is mainly used to press the rubber into a film of a certain thickness and surface shape, or to laminate the rubber into a multi-layer film or laminate it with other materials into a rubber tape. During the calendering process, the rubber is squeezed and stretched in the gap between the calendering rollers, thereby reducing the thickness and increasing the surface area. At the same time, due to the rotation and friction of the calendering rollers, the rubber will also be subject to a certain shear force and thermal effect, which helps to improve the properties of the rubber and improve the quality of the product.

[0004] The calendering process not only helps to achieve a good bond between the graphite powder and the substrate, but also improves the overall performance and stability of the graphite grounding wire. Through calendering, the gaps and bubbles between the graphite powder and the substrate can be eliminated, making the grounding wire denser and more uniform. Application number: CN202020642740.6, provides a calendering device for the production of graphite grounding wires. By adopting a blanking screen assembly and a paving assembly, the graphite powder exiting the graphite puffing device is evenly spread, resulting in a technical effect of improving product consistency. However, when the graphite powder is calendered onto the substrate by the calendering device, the graphite powder may adhere to the pressing roller, and the adhered graphite powder will accumulate on the pressing roller, affecting the cleanliness of the pressing roller and the calendering effect. As the calendering process proceeds, these accumulated graphite powders may gradually increase, resulting in an uneven surface of the pressing roller, thereby affecting the bonding quality between the graphite layer and the substrate.

[0005] Therefore, it is necessary to provide a rolling device for the production of graphite grounding wires to solve the above technical problems. Utility Model Content

[0021] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0022] Please refer to Figure 1 , Figure 2 and Figure 3 ,in Figure 1 A structural schematic diagram of a preferred embodiment of a calendering device for producing graphite grounding wire provided by the utility model; Figure 2 for Figure 1 A schematic diagram of the structure of the rear view of the body shown; Figure 3 for Figure 2 The schematic diagram of the structure of the support frame part is shown, a rolling device for producing graphite grounding wire, comprising: a machine body 1, an adjusting component 2 is arranged on the top of the machine body 1, and a cleaning component 3 is arranged inside the adjusting component 2;

[0023] The adjustment assembly 2 includes a support frame 21 disposed on the left side of the top of the machine body 1, a sliding groove 22 is vertically disposed on the inner side of the support frame 21, a sliding plate 23 is disposed on the inner side of the sliding groove 22 so as to slide up and down along the height direction thereof, and an upper roller 24 is disposed on the inner side of the sliding plate 23 so as to be rotatable longitudinally;

[0024] By setting the sliding plate 23 with movable height, the height position of the upper roller 24 can be adjusted at will to adapt to the rolling work of the graphite grounding wire with different requirements.

[0025] The cleaning assembly 3 includes a rotatable cleaning brush 31 which is longitudinally arranged on the inner side of the sliding plate 23 and located on the left side of the upper roller 24. The front end of the cleaning brush 31 passes through the inner side of the sliding plate 23 and extends to the front side of the support frame 21. The front end of the cleaning brush 31 is provided with a belt 32 through a belt pulley.

[0026] A cleaning brush 31 is also provided at the shaft of the lower roller 5. The rotation of the output end of the first motor 34 drives the rotation of the belt pulley, which in turn drives the rotation of the belt 32 and drives the rotation of the cleaning brush 31. The cleaning brush 31 is close to the pressure roller, and by setting belt pulleys of different sizes, the rotation speed of the cleaning brush 31 can be greater than the rotation speed of the upper roller 24, thereby achieving a cleaning effect.

[0027] A rotating frame 25 is provided at the top of the support frame 21, and a bidirectional threaded screw 26 is rotatably provided on the inner side of the rotating frame 25. Two threaded sleeves 27 are provided on the circumferential side surface of the bidirectional threaded screw 26 so as to be movable forward and backward along its length direction. A rotating plate 28 is rotatably provided at the bottom of the two threaded sleeves 27, and the bottoms of the two rotating plates 28 are rotatably connected to the top of the sliding plate 23.

[0028] The circumferential side surface of the bidirectional threaded screw 26 is provided with reverse threads, and the bidirectional threaded screw 26 is driven to rotate by rotating the rotating handle 4, thereby driving the relative movement of the two threaded sleeves 27. Through the connection relationship between the threaded sleeves 27, the rotating plate 28 and the sliding plate 23, when the two threaded sleeves 27 move relative to or apart, the upper roller 24 at the bottom is lifted or pressed down; in this way, the problem of left and right height errors that are prone to occur during traditional spacing adjustment is solved.

[0029] The cleaning assembly 3 also includes a placement plate 33 slidably arranged on the front side of the support frame 21. A first motor 34 for driving the upper roller 24 to rotate is arranged on the top of the placement plate 33. The output end on the back side of the first motor 34 is sleeved on the right side of the belt pulley and the belt 32. The output end on the back side of the first motor 34 is fixedly connected to the front end of the upper roller 24.

[0030] The front end of the bidirectional threaded screw 26 passes through the inner side of the rotating frame 25 and extends to the front side thereof. A rotating handle 4 is provided at the front end of the bidirectional threaded screw 26 , and a lower roller 5 is rotatably provided at the bottom of the inner side of the support frame 21 .

[0031] A support base 6 is arranged on the right side of the top of the machine body 1, and two rotating rods 7 are rotatably arranged longitudinally on the inner side of the support base 6. Pulleys 8 are arranged at both front and rear ends of the two rotating rods 7, and transmission belts 9 are sleeved on the peripheral side surfaces of each two sets of pulleys 8.

[0032] A second motor for driving the left rotating rod 7 to rotate is arranged inside the support seat 6. The second motor is a DC motor. When the pulley 8 rotates, it drives the transmission belt 9 to rotate, thereby driving the movement of the fixed block 10 and the left and right movement of the paving plate 11, thereby flattening the graphite powder and improving the calendering effect.

[0033] A fixing block 10 is disposed on the top of each of the two transmission belts 9 , a material spreading plate 11 is disposed on one side opposite to the two fixing blocks 10 , and a material discharging point 12 is disposed on the back side of the machine body 1 .

[0034] The working principle of a calendering device for producing graphite grounding wire provided by the utility model is as follows:

[0035] Step 1: When the graphite powder falls onto the substrate at the discharge port 12, the belt pulley 8 rotates to drive the transmission belt 9 to rotate, thereby driving the fixed block 10 to move, and driving the paving plate 11 to move left and right, so as to flatten the graphite powder and improve the calendering effect;

[0036] Step 2: When the spacing between the upper and lower pressure rollers needs to be adjusted, the bidirectional threaded screw 26 is driven to rotate by rotating the rotating handle 4, thereby driving the relative movement of the two threaded sleeves 27. Through the connection relationship between the threaded sleeves 27, the rotating plate 28 and the sliding plate 23, when the two threaded sleeves 27 move relative to or away from each other, the upper roller 24 at the bottom is lifted or pressed down;

[0037] Step 3: The output end of the first motor 34 is rotated to drive the belt pulley to rotate, and then the belt 32 is driven to rotate, and the cleaning brush 31 is driven to rotate. The cleaning brush 31 is close to the pressure roller, and by setting belt pulleys of different sizes, the rotation speed of the cleaning brush 31 can be greater than the rotation speed of the upper roller 24, thereby achieving a cleaning effect.

[0038] Compared with the related art, the calendering device for producing graphite grounding wire provided by the utility model has the following beneficial effects:

[0039] The rotation of the output end of the first motor 34 drives the rotation of the belt pulley, which in turn drives the rotation of the belt 32 and the rotation of the cleaning brush 31. The cleaning brush 31 is close to the pressure roller, and by setting belt pulleys of different sizes, the rotation speed of the cleaning brush 31 can be greater than the rotation speed of the upper roller 24. The structure is simple and practical, and can be used to clean the pressure roller during operation. Compared with the traditional calendering device that adjusts the spacing, it can also achieve simultaneous adjustment to avoid the problem of left and right height errors.
