Description

A wear-resistant device for the chuck of a rubber grinding roller machine Technical Field

[0001] This utility model relates to the field of rubber grinding roller machines, specifically a wear-resistant device for the chuck of a rubber grinding roller machine. Background Technology

[0002] A rubber roller grinding machine is a specialized piece of equipment used for precision grinding of rubber roller surfaces. It is widely used in industries such as printing, papermaking, plastics, textiles, and metallurgy. Its core function is to remove excess material from the surface of the rubber roller through the relative motion of the grinding wheel and the rubber roller, achieving the required dimensional accuracy, shape accuracy, and surface roughness, thereby restoring or improving the performance of the rubber roller.

[0003] In the prior art, when the rubber roller grinding machine limits and clamps the end of the rubber roller, there is a clamping method that uses a hydraulic cylinder to drive the chuck for limiting, as shown in Figure 1. During use and observation, it was found that because the chuck of the rubber roller grinding machine holds the rubber roller for a long time, the chuck wears quickly, which affects the accuracy of the diameter of the return grinding roller.

[0004] Therefore, a wear-resistant device for the chuck of a rubber grinding roller is proposed to address the above problems. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The wear-resistant device for a chuck of a rubber roller grinding machine, as described in this utility model, includes a rubber roller and a support base; a hydraulic cylinder is rotatably connected to the top of the support base; a rotating seat is rotatably connected to the output end of the hydraulic cylinder, and the rotating seat and the support base are rotatably connected; a pressure block is fixedly connected to the top of the rotating seat; a chuck is fixedly connected to the top of the support base; a V-shaped groove is opened on the inner wall of the chuck, and a silicone sleeve is fixedly connected to both the inner wall of the chuck groove and the inner wall of the pressure block; the rubber roller is located between the chuck and the pressure block; by setting the silicone sleeve, the direct contact between the chuck, the pressure block and the rubber roller can be reduced, thereby reducing the wear caused by friction on the surfaces of the pressure block and the chuck, and reducing the positional error of the axis of the rubber roller when it is clamped due to wear.

[0007] Preferably, the pressure block is symmetrically fixed with fixing plates on both sides; a screw is threaded through the middle of the fixing plate; a pressure plate is rotatably connected to the end of the screw, and the pressure plate has an arc-shaped structure; multiple sliding rods are fixed to one side of the pressure plate; the sliding rods and the fixing plate are slidably connected through each other; multiple ball bearings are rotatably connected to the inner wall of the pressure plate; through the cooperation of the screw and the pressure plate, additional limiting and support functions can be provided for the outer wall of the rubber roller, improving the stability of the rubber roller during fine grinding.

[0008] Preferably, a connecting rod is fixed between the pair of slide rods at the top; the connecting rod is located on one side of the fixed plate; by setting the connecting rod, the pair of screws can be connected into a whole system by pulling the slide rods together, thereby improving the stability of the pressure plate when it squeezes and limits the rubber roller, reducing the occurrence of screw reversal, and the screw pitch can also be appropriately reduced to reduce the occurrence of reversal.

[0009] Preferably, multiple pairs of circular plates are fixedly attached to the surface of the connecting rod; a fixing ring is provided between each pair of circular plates; the fixing ring and the connecting rod are in clearance fit, and a vertical rod is fixedly attached to the bottom of the fixing ring; multiple circular holes are opened on the top of the pressure block, and the circular holes and the vertical rod are correspondingly arranged; after the position of the pressure plate is adjusted, the vertical rod can be aligned and inserted into the circular hole by rotating the fixing ring, so that the connecting rod can be subjected to the locking action between the fixing ring and the pressure block, further improving the stability of the screw during operation. At the same time, when adjusting the screw, the fixing ring can be rotated to disengage it from the circular hole so that it will not obstruct the movement of the connecting rod.

[0010] Preferably, a cooling pipe is fixedly connected to the inner wall of the chuck; one side of the cooling pipe is connected to an air inlet pipe, and the other side of the cooling pipe is connected to multiple nozzles; when the rubber roller is rotating for fine grinding, the air inlet pipe can be connected to a cold air supply device so that the cooling airflow is sprayed out from the nozzles through the air inlet pipe and the cooling pipe, with the nozzles facing the surface of the rubber roller, thereby cooling the end of the rubber roller and cooling the inner wall of the chuck and the surface of the pressure block under the action of flow, thereby reducing the heat caused by friction between the rubber roller, the pressure block, and the chuck, and thus reducing the softening and plastic deformation of the surface of the pressure block, the chuck, and the rubber roller due to high temperature.

[0011] Preferably, the outer wall of the cooling pipe is symmetrically fixed with guide plates, and the guide plates are L-shaped structures; by setting the guide plates, the cooling airflow ejected from one side of the cooling pipe can be guided and concentrated, thereby increasing the airflow reaching the surface of the rubber roller.

[0012] The advantages of this utility model are:

[0013] 1.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Specific implementation examples are given below.

[0024] Please refer to Figures 1 to 5. The present invention provides an anti-wear device for a rubber roller chuck in an embodiment of the present invention, comprising a rubber roller 1 and a support base 12. A hydraulic cylinder 13 is rotatably connected to the top of the support base 12. A rotating seat 14 is rotatably connected to the output end of the hydraulic cylinder 13, and the rotating seat 14 and the support base 12 are rotatably connected. A pressure block 15 is fixedly connected to the top of the rotating seat 14. A chuck 16 is fixedly connected to the top of the support base 12. A V-shaped groove is formed on the inner wall of the chuck 16, and silicone sleeves 17 are fixedly connected to both the inner wall of the groove and the inner wall of the pressure block 15. The rubber roller 1 is located between the chuck 16 and the pressure block 15. During operation, the rubber roller 1 can be hoisted to the top of the support base 12 and adjusted to be concentric with the inner groove of the chuck 16. Simultaneously, by activating the hydraulic cylinder 13, the rotating seat 14 is driven to rotate along the support base 12. The support base 12, along with the pressure block 15, moves closer to one side of the rubber roller 1 until the pressure block 15 and the chuck 16 are aligned. The inner groove 6 can be used to limit one end of the rubber roller 1. The sprocket at the end of the rubber roller 1 will be located on both sides of the chuck 16. At the same time, the other end of the rubber roller 1 can be clamped by the power component. The power component can be any existing technology to achieve clamping and rotation of the other end of the rubber roller 1. Then, the slowly rotating rubber roller 1 can be finely ground by the grinding wheel. The specific structure of the grinding mechanism of the rubber roller 1 and the power component will not be described here. When the rubber roller 1 rotates, there is relative friction between it and the inner wall of the chuck 16 and the pressure block 15. At this time, by setting the silicone sleeve 17, the smoothness of the contact surface between the chuck 16 and the pressure block 15 and the rubber roller 1 can be improved, thereby reducing the wear caused by friction between the chuck 16, the pressure block 15 and the rubber roller 1. By setting the silicone sleeve 17, the direct contact between the chuck 16, the pressure block 15 and the rubber roller 1 can be reduced, thereby reducing the wear caused by friction on the surface of the pressure block 15 and the chuck 16, and reducing the positional error of the axis when the rubber roller 1 is clamped due to wear.

[0025] Please refer to Figure 4. The pressure block 15 has symmetrically fixed plates 2 on both sides; a screw 22 is threaded through the middle of the fixed plate 2; a pressure plate 23 is rotatably connected to the end of the screw 22, and the pressure plate 23 has an arc-shaped structure; multiple sliding rods 25 are fixed to one side of the pressure plate 23; the sliding rods 25 and the fixed plate 2 are slidably connected through each other; multiple ball bearings 24 are rotatably connected to the inner wall of the pressure plate 23; after the chuck 16 and the pressure block 15 limit the movement of the rubber roller 1, the pressure plate 23 can be driven to move in the threaded transmission by simultaneously rotating the screws 22 on both sides. Guided by the slide bar 25, the roller 1 moves closer to the outer wall of the roller 1 until the pressure plate 23 can squeeze the roller 1. This improves the stability of the device clamping the end of the roller 1 and compensates for the error caused by wear between the pressure block 15 and the chuck 16, thereby improving the accuracy of the roller 1's axis during grinding. Finally, the ball bearings 24 reduce the friction between the roller 1 and the pressure plate 23. Through the cooperation of the screw 22 and the pressure plate 23, the outer wall of the roller 1 is provided with additional limiting and support, improving the stability of the roller 1 during fine grinding.

[0026] Please refer to Figure 4. A connecting rod 3 is fixed between the pair of slide rods 25 located at the top. The connecting rod 3 is located on one side of the fixing plate 2. By setting the connecting rod 3, the pair of screws 22 can be connected into a whole system by pulling the slide rods 25 together, thereby improving the stability of the pressure plate 23 when it squeezes and limits the rubber roller 1, reducing the possibility of the screws 22 reversing. At the same time, the pitch of the screws 22 can also be appropriately reduced to reduce the possibility of reversing.

[0027] Please refer to Figures 3 and 4. The surface of the connecting rod 3 is fixed with multiple pairs of circular plates 42; a fixing ring 4 is provided between each pair of circular plates 42; the fixing ring 4 and the connecting rod 3 are in clearance fit, and a vertical rod 43 is fixed to the bottom of the fixing ring 4; multiple circular holes 44 are opened on the top of the pressure block 15, and the circular holes 44 and the vertical rod 43 are correspondingly arranged; after the position of the pressure plate 23 is adjusted, the vertical rod 43 can be aligned and inserted into the circular hole 44 by rotating the fixing ring 4, so that the connecting rod 3 can be subjected to the locking action between the fixing ring 4 and the pressure block 15, further improving the stability of the screw 22 during operation. At the same time, when adjusting the screw 22, the fixing ring 4 can be rotated to disengage it from the circular hole 44 so that it will not hinder the movement of the connecting rod 3.

[0028] Please refer to Figure 5. A cooling pipe 5 is fixedly connected to the inner wall of the chuck 16. One side of the cooling pipe 5 is connected to an air inlet pipe 52, and the other side of the cooling pipe 5 is connected to multiple nozzles. When the rubber roller 1 is rotating for fine grinding, the air inlet pipe 52 can be connected to a cold air supply device so that the cooling airflow is sprayed out from the nozzles through the air inlet pipe 52 and the cooling pipe 5. The nozzles face the surface of the rubber roller 1, which can cool the end of the rubber roller 1. Under the action of flow, the inner wall of the chuck 16 and the surface of the pressure block 15 can also be cooled, thereby reducing the heat caused by friction between the rubber roller 1, the pressure block 15, and the chuck 16, and thus reducing the softening and plastic deformation of the pressure block 15, the chuck 16, and the surface of the rubber roller 1 due to high temperature.

[0029] Please refer to Figure 5. The outer wall of the cooling pipe 5 is symmetrically fixed with guide plates 6, and the guide plates 6 have an L-shaped structure. By setting the guide plates 6, the cooling airflow ejected from one side of the cooling pipe 5 can be guided and concentrated, thereby increasing the airflow reaching the surface of the rubber roller 1.

[0030] Working principle: The rubber roller 1 is hoisted to the top of the support base 12 and adjusted to be concentric with the inner groove of the chuck 16. Simultaneously, the hydraulic cylinder 13 is activated to drive the rotating seat 14 to rotate along the support base 12. The support base 12, along with the pressure block 15, moves closer to one side of the rubber roller 1 until the pressure block 15 and the inner groove of the chuck 16 engage to limit one end of the rubber roller 1. The sprocket at the end of the rubber roller 1 will be positioned on both sides of the chuck 16. Meanwhile, the other end of the rubber roller 1 can be clamped by a power assembly. The power assembly can be any existing technology to achieve clamping and rotation of the other end of the rubber roller 1. Subsequently, the slowly rotating rubber roller 1 can be finely ground by a grinding wheel. The specific structure of the grinding mechanism and the power assembly of the rubber roller 1 will not be described in detail here. During rotation, there is relative friction between the chuck 16, the inner wall of the clamp 16, and the pressure block 15. By installing a silicone sleeve 17, the smoothness of the contact surfaces between the chuck 16, the pressure block 15, and the rubber roller 1 can be improved, thereby reducing wear caused by friction between the chuck 16, the pressure block 15, and the rubber roller 1. After the chuck 16 and the pressure block 15 limit the rubber roller 1, the two screws 22 can be rotated simultaneously to drive the pressure plate 23 towards the outer wall of the rubber roller 1 under the action of the threaded transmission and the guidance of the slide bar 25, until the pressure plate 23 can squeeze the rubber roller 1. This improves the stability of the device in clamping the end of the rubber roller 1 and compensates for errors caused by wear between the pressure block 15 and the chuck 16, thereby improving the axial stability of the rubber roller 1 during grinding. To improve the accuracy of the screw, the friction between the rubber roller 1 and the pressure plate 23 can be reduced by setting the ball bearing 24. By setting the connecting rod 3, the pair of screws 22 can be connected into a whole system by pulling the slide rod 25, thereby improving the stability of the pressure plate 23 when it squeezes and limits the rubber roller 1, reducing the possibility of the screw 22 reversing. At the same time, the pitch of the screw 22 can also be appropriately reduced to reduce the possibility of reversing. After the position of the pressure plate 23 is adjusted, the upright rod 43 can be aligned and inserted into the round hole 44 by rotating the fixing ring 4, so that the connecting rod 3 can be subject to the locking action between the fixing ring 4 and the pressure block 15, further improving the stability of the screw 22 during operation. At the same time, when adjusting the screw 22, the fixing ring 4 can be rotated to make the screw 22 more stable. Its exit hole 44 prevents it from obstructing the movement of the connecting rod 3. When the rubber roller 1 is rotating for fine grinding, the air inlet pipe 52 can be connected to the cold air supply equipment so that the cooling airflow is sprayed out from the nozzle through the air inlet pipe 52 and the cooling pipe 5. The nozzle faces the surface of the rubber roller 1, which can cool the end of the rubber roller 1. Under the action of flow, it can also cool the inner wall of the chuck 16 and the surface of the pressure block 15, thereby reducing the heat caused by friction between the rubber roller 1, the pressure block 15, and the chuck 16, and thus reducing the softening and plastic deformation of the pressure block 15, the chuck 16, and the surface of the rubber roller 1 due to high temperature. By setting the guide plate 6, the cooling airflow sprayed from one side of the cooling pipe 5 can be guided and concentrated, thereby increasing the airflow reaching the surface of the rubber roller 1.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
