A flexible rubber roller testing device and method

Abstract

This invention relates to the field of rubber roller testing technology, and particularly to a flexible rubber roller testing device and method. It includes a base; two symmetrically positioned limiting mechanisms are provided on the base; and a testing mechanism is located between the two fixing mechanisms at the upper end of the base. The limiting mechanisms of this invention facilitate quick assembly and disassembly of the rubber roller, improving the efficiency of rubber roller testing. Furthermore, the dual fixing through end compression and sidewall compression increases the number of fixing points. Even if one point fails, other points can still maintain a certain fixing strength, ensuring the stability of the rubber roller and thus guaranteeing the accuracy of subsequent testing results. The testing mechanism can test both the elasticity and wear resistance of the rubber roller, reducing the space occupied by the equipment and further improving testing efficiency. In addition, the adjusting and driving parts can change the squeezing force of the pressure block and grinding block on the rubber roller, thereby allowing testing of whether the elasticity and wear resistance of the rubber roller are qualified under different pressures and frictions.

Description

Technical Field

[0001] This invention relates to the field of rubber roller testing technology, and in particular to a flexible rubber roller testing device and method. Background Technology

[0002] Flexible rubber rollers typically refer to cylindrical rollers whose surfaces are covered with elastic materials (such as rubber, polyurethane, etc.). They possess a certain degree of flexibility and elasticity, enabling them to adapt to slight surface unevenness and generate uniform contact force when pressure is applied. To ensure good adhesion between the rubber roller and the workpiece and to extend the roller's service life, elasticity and abrasion resistance tests are performed. These tests involve pressing the roller with appropriate equipment to assess elasticity and rubbing it to assess abrasion resistance.

[0003] Currently, the main problems in the inspection and processing of rubber rollers are as follows: Elasticity testing and abrasion resistance testing require separate equipment, necessitating transfer from one machine to another for each test. This transfer process consumes additional time, and the two machines occupy significant space. Secondly, the usual methods for fixing rubber rollers are inserting both ends into corresponding bearing seats or clamping them with a chuck. However, inserting the roller into the bearing seats is cumbersome and affects testing efficiency. While chuck clamping fixation relies solely on the squeezing of the jaws, the smooth ends of the roller reduce the chuck's gripping effect, weakening the roller's stability. Furthermore, failure at any fixing point can affect the entire chuck's gripping effect, potentially impacting the results of subsequent abrasion resistance tests. Summary of the Invention

[0004] In view of the above problems, this application provides a flexible rubber roller testing device and method to solve the aforementioned technical problems.

[0005] To achieve the above objectives, the embodiments of this application provide the following technical solutions: The first aspect of the embodiments of this application provides a flexible rubber roller detection device, including a base; the base is provided with two left-right symmetrical limiting mechanisms, and the upper end of the base is provided with a detection mechanism located between the two fixing mechanisms.

[0006] The limiting mechanism includes a fixed plate. Two symmetrical fixed plates are fixedly installed on the upper end of the base. A U-shaped groove is provided on the fixed plate. An arc plate is coaxially rotatably installed in the arc section of the U-shaped groove. The front and rear ends of the fixed plate are coaxially provided with annular grooves with the arc plate. A slider that is fixedly connected to the arc plate is slidably installed in the annular groove.

[0007] The detection mechanism includes a support plate. Two symmetrical support plates are fixedly installed on the upper end of the base. A U-shaped plate is slidably installed between the two support plates. A grinding block is fixedly installed on the upper left side of the horizontal section of the U-shaped plate. A pressure block is slidably installed on the upper right side of the horizontal section of the U-shaped plate. A cover plate is fixedly installed on the upper end of the vertical section of the U-shaped plate. The cover plate is provided with an adjustment part for driving the pressure block to move left and right to change the squeezing force of the pressure block on the rubber roller.

[0008] The arc-shaped plate is provided with a fixing part for fixing the rubber roller. Between the support plate and the fixing part, there is a driving part for driving the arc-shaped plate to move left and right, the right arc-shaped plate to rotate intermittently, and changing the squeezing force of the grinding block on the rubber roller. The base is also provided with an execution part for cooperating with the fixing part on the left limiting mechanism to drive the corresponding arc-shaped plate to rotate.

[0009] As a preferred embodiment, the fixing part includes a disc, and the two opposite ends of the two arc-shaped plates located on the same limiting mechanism are coaxially fixedly mounted with discs. A spline groove is opened in the middle of the disc, and a spline shaft slides through the spline groove. A shaft plate is rotatably mounted on the end of the spline shaft away from the fixing plate. The shaft plate is slidably mounted on the upper end of the base. An extrusion disc is fixedly mounted on the end of the spline shaft close to the fixing plate. An extrusion component is provided between the extrusion disc and the disc for extruding the rubber roller and fixing it to the arc-shaped plate. A pushing component is provided on the base for driving the shaft plate to move back and forth.

[0010] As a preferred embodiment, the driving unit includes support columns. Two symmetrical support columns are fixedly installed at both the front and rear ends of the U-shaped plate. The support plate has a first groove corresponding to each support column. The two support columns located on the same vertical section of the U-shaped plate slide through the corresponding first groove and are then fixedly installed together with a connecting plate. The connecting plate has a waist-shaped groove. The opposite sides of the two connecting plates are provided with upright plates fixedly installed on the base. Two symmetrical shafts are rotatably installed on the upright plates. The right disk and the right shaft are connected by a spur gear set, and the outer diameter of the spur gear on the shaft is smaller than the outer diameter of the spur gear on the disk. The two shafts are connected by an incomplete gear mechanism. The base and the support plate are jointly provided with a transmission component for driving the left shaft to rotate. The incomplete gear mechanism is provided with a push-pull component for driving the connecting plate to move left and right.

[0011] As a preferred embodiment, the push-pull component includes a guide post, and the incomplete gear mechanism consists of a driving gear and a driven gear. The driving gear is fixedly installed on the left shaft, and the driven gear is fixedly installed on the right shaft. A guide post that slides with the waist-shaped groove is fixedly installed at the eccentric end of the driving gear away from the vertical plate.

[0012] As a preferred embodiment, the adjusting part includes inclined grooves. The upper end of the pressure block has two inclined grooves that slope from left to right and back. The cover plate has a second waist groove that corresponds to the inclined grooves. An electric telescopic rod is fixedly installed on the upper end of the cover plate. A drive plate is fixedly installed on the telescopic section of the electric telescopic rod. A roller is fixedly installed on the lower end of the drive plate at a position corresponding to the second waist groove. The roller slides through the corresponding second waist groove into the corresponding inclined groove.

[0013] As a preferred embodiment, the pushing component includes a bearing plate, and bearing plates are fixedly installed at both the front and rear ends of the base. A bidirectional screw is rotatably installed on both bearing plates. The bidirectional screw rotates through two support plates. Both threaded sections of the bidirectional screw are threadedly connected to screw plates that are slidably installed on the base. Two opposing shaft plates are fixedly connected to their corresponding screw plates. A No. 1 motor with an output shaft fixedly connected to the bidirectional screw is fixedly installed at the rear end of the rear bearing plate.

[0014] As a preferred embodiment, the actuator includes a rotating shaft. The upper end of the base is rotatably mounted with the rotating shaft located to the left of the left limiting mechanism via a bearing seat. A second motor with an output shaft fixedly connected to the rotating shaft is fixedly mounted on the base. The disc located to the left is connected to the rotating shaft via a first belt pulley mechanism.

[0015] As a preferred embodiment, the transmission component includes a No. 3 motor. A No. 3 motor is fixedly installed on the upper end of the base between the front upright plate and the front screw plate. The output shaft of the No. 3 motor is fixedly installed with a drive rod that rotates through the two support plates. The shaft on the left side is connected to the drive rod by a No. 2 pulley mechanism.

[0016] As a preferred embodiment, the extrusion component includes an extrusion plate. Two extrusion plates, which are symmetrically arranged on the left and right and located above the arc-shaped plate, are slidably installed along the radial direction of the disc near the fixed plate. A connecting rod is hinged between the extrusion plate and the extrusion disc, and the connecting rod is inclined from bottom to top toward the disc.

[0017] The second aspect of this application provides a method for detecting flexible rubber rollers, which is completed with the assistance of a flexible rubber roller detection device, including the following steps: S1, the right-side limiting mechanism fixes the rubber roller through the fixing part.

[0018] S2. The drive unit drives the pressure block to move back and forth to perform elasticity detection on the intermittently rotating rubber roller.

[0019] S3. The left-side limiting mechanism fixes the rubber roller after elasticity testing through the fixing part.

[0020] S4. The drive unit drives the grinding block to contact the rubber roller, and the actuator drives the fixed rubber roller to rotate in order to perform wear resistance testing.

[0021] The above-described one or more technical solutions in the embodiments of the present invention have at least one of the following technical effects:

[0022] I. The limiting mechanism of this invention allows for convenient and rapid assembly and disassembly of the rubber roller, thereby improving the efficiency of rubber roller inspection and processing. Furthermore, by using both end-pressing and side-wall-pressing methods for fixation, the number and distribution range of fixing points are increased. More fixing points mean that even if one point fails, other points can still maintain a certain fixing strength, thus ensuring the stability of the rubber roller and consequently the accuracy of subsequent test results. The testing mechanism can test both the elasticity and wear resistance of the rubber roller, thereby reducing the space occupied by the equipment and further improving testing efficiency. In addition, the adjusting and driving parts can change the pressing force of the pressure block and grinding block on the rubber roller, thus enabling the testing of whether the elasticity and wear resistance of the rubber roller are qualified under different pressures and friction forces.

[0023] Second, the limiting mechanism set in this invention uses two opposing extrusion discs to press the rubber roller, thereby fixing it in one step. At the same time, the extrusion discs also drive the extrusion plate through the connecting rod to press the rubber roller tightly against the arc plate, thereby fixing the rubber roller in two steps. This ensures the stability of the rubber roller rotation, thus ensuring the accuracy of subsequent test results. It also facilitates the disassembly and assembly of the rubber roller, improving the testing efficiency.

[0024] Third, the testing mechanism of this invention integrates elasticity testing and abrasion resistance testing on the same equipment to reduce the space occupied by the equipment and reduce the extra time generated by the movement of the rubber roller, thereby improving the testing efficiency. In addition, the pressure block can be moved by the adjustment part to change the force of the pressure block squeezing the rubber roller driven by the drive part, and the force of the grinding block squeezing the rubber roller can also be changed by the drive part to change the friction between the grinding block and the rubber roller, thereby gaining a more comprehensive understanding of the performance of the rubber roller.

[0025] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0034] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] like Figure 1 As shown, a flexible rubber roller testing device includes a base 1; two left-right symmetrical limiting mechanisms 2 are provided on the base 1, and a testing mechanism 3 located between the two fixing mechanisms is provided at the upper end of the base 1.

[0036] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the limiting mechanism 2 includes a fixed plate 20. Two fixed plates 20 symmetrically arranged front and back are fixedly installed on the upper end of the base 1. A U-shaped groove is provided on the fixed plate 20. An arc plate 21 is coaxially rotatably installed in the arc section of the U-shaped groove. The front and rear ends of the fixed plate 20 are coaxially provided with annular grooves 22 with the arc plate 21. A slider 23 fixedly connected to the arc plate 21 is slidably installed in the annular groove 22.

[0037] like Figure 1 , Figure 2 and Figure 3 As shown, the detection mechanism 3 includes a support plate 30. Two symmetrical support plates 30 are fixedly installed on the upper end of the base 1. A U-shaped plate 31 is slidably installed between the two support plates 30. A grinding block 32 is fixedly installed on the upper left side of the horizontal section of the U-shaped plate 31. A pressure block 33 is slidably installed on the upper right side of the horizontal section of the U-shaped plate 31. A cover plate is fixedly installed on the upper end of the vertical section of the U-shaped plate 31. An adjustment part 34 is provided on the cover plate for driving the pressure block 33 to move left and right to change the squeezing force of the pressure block 33 on the rubber roller.

[0038] like Figure 1 and Figure 2 As shown, the arc plate 21 is provided with a fixing part 4 for fixing the rubber roller. Between the support plate 30 and the fixing part 4, there is a driving part 5 for driving the arc plate 31 to move left and right, the right arc plate 21 to rotate intermittently, and changing the squeezing force of the grinding block 32 on the rubber roller. The base 1 is also provided with an execution part 6 for cooperating with the fixing part 4 on the left limiting mechanism 2 to drive the corresponding arc plate 21 to rotate.

[0039] In practice, the rubber roller is manually placed on the limiting mechanism 2 on the right side, so that the front and rear ends of the rubber roller are located within the corresponding arc plate 21. Then, the fixing part 4 fixes the rubber roller on the arc plate 21. The driving part 5 drives the U-shaped plate 31 to move back and forth left and right. The U-shaped plate 31 drives the pressure block 33 to squeeze the rubber roller. Each time the rubber roller is squeezed, the driving part 5 will drive the rubber roller to rotate a certain angle so that it can be squeezed again, so that the rubber roller is completely squeezed. The squeezing force of the pressure block 33 on the rubber roller can be changed by the adjusting part 34. After squeezing, the rubber roller is removed. The rubber roller is tested manually or by corresponding instruments to see if it will spring back after being squeezed, so as to determine whether the elasticity of the rubber roller is qualified.

[0040] It should be noted that a displacement sensor can be used to detect whether a rubber roller will spring back after being squeezed. The displacement sensor measures the change in position of a point on the surface of the rubber roller before and after squeezing to determine whether the rubber roller has recovered. After sensing a change in the distance between itself and a point on the surface of the rubber roller, the displacement sensor converts the sensed displacement signal into an electrical signal. The electrical signal is then amplified, filtered, and processed before being converted into a digital signal. The digital signal is then transmitted to the display system to display the amount of displacement that occurred at that point on the surface of the rubber roller. If the displacement is 0, it indicates that the rubber roller has springed back after being squeezed.

[0041] After the elasticity test, the rubber roller is fixed to the left limiting mechanism 2. Then, the drive unit 5 drives the grinding block 32 to fit with the rubber roller, and the execution unit 6 drives the fixed rubber roller to rotate. When the rubber roller rotates, its surface will be rubbed by the grinding block 32. After the rubber roller is rubbed, the rubber roller is removed and the changes on the surface of the rubber roller are checked manually or by corresponding instruments to determine whether the wear resistance of the rubber roller is qualified.

[0042] It should be noted that a machine vision system can be used when inspecting the surface of the removed rubber rollers.

[0043] like Figure 1 , Figure 3 and Figure 4 As shown, the fixing part 4 includes a disc 40. The two opposite ends of the two arc-shaped plates 21 located on the same limiting mechanism 2 are coaxially fixed with the disc 40. A spline groove is opened in the middle of the disc 40. A spline shaft 41 slides through the spline groove. A shaft plate 42 is rotatably installed at the end of the spline shaft 41 away from the fixing plate 20. The shaft plate 42 is slidably installed at the upper end of the base 1. An extrusion disc 43 is fixedly installed at the end of the spline shaft 41 close to the fixing plate 20. An extrusion member 44 is provided between the extrusion disc 43 and the disc 40 for extruding the rubber roller and fixing it to the arc-shaped plate 21. A pushing member 45 is provided on the base 1 for driving the shaft plate 42 to move back and forth.

[0044] like Figure 1 , Figure 2 and Figure 3 As shown, the pushing component 45 includes a bearing plate. Both the front and rear ends of the base 1 are fixedly installed with bearing plates. A bidirectional screw 450 is rotatably installed on both bearing plates. The bidirectional screw 450 rotatably passes through two support plates 30. Both threaded sections of the bidirectional screw 450 are threadedly connected to screw plates 451 that are slidably installed on the base 1. Two opposing shaft plates 42 are fixedly connected to the corresponding screw plates 451. The rear end of the rear bearing plate is fixedly installed with an output shaft that is fixedly connected to the bidirectional screw 450. A No. 1 motor 452 is fixedly installed at the rear end of the rear bearing plate.

[0045] like Figure 1 , Figure 3 and Figure 4As shown, the extrusion component 44 includes an extrusion plate 440. Two extrusion plates 440, which are symmetrical about left and right and located above the arc plate 21, are slidably installed along the radial direction of the disc 40 near the fixed plate 20. A connecting rod 441 is hinged between the extrusion plate 440 and the extrusion disc 43, and the connecting rod 441 is inclined from bottom to top towards the disc 40.

[0046] In actual operation, the first motor 452 rotates forward, driving the bidirectional screw 450 to rotate. The bidirectional screw 450 then drives the two screw plates 451 to move closer to each other. The screw plates 451 then drive the spline shaft 41 to move towards the rubber roller through the shaft plate 42. The two spline shafts 41, which are opposite each other, squeeze, fix, and align the rubber roller through the corresponding extrusion plate 43. During the movement of the spline shaft 41, it also drives the extrusion plate 440 to move towards the rubber roller through the connecting rod 441, so that the rubber roller is squeezed and fixed tightly against the arc plate 21. Then, the drive unit 5 drives the disc 40 to rotate. The disc 40 then drives the fixed rubber roller to rotate through the spline shaft 41 for the inspection and processing of the rubber roller.

[0047] After the inspection is completed, the No. 1 motor 452 reverses and drives the two screw plates 451 away from each other via the bidirectional screw 450. The screw plates 451 then drive the spline shaft 41 away from the rubber roller via the shaft plate 42, thereby releasing the fixation of the rubber roller. Thus, the rubber roller can be quickly disassembled and assembled according to the above operation, thereby improving the efficiency of rubber roller inspection and processing.

[0048] like Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, the driving unit 5 includes support columns 50. Two symmetrical support columns 50 are fixedly installed at both the front and rear ends of the U-shaped plate 31. The support plate 30 has a first groove corresponding to each support column 50. The two support columns 50 located on the same vertical section of the U-shaped plate 31 slide through the corresponding first groove and are fixedly installed together with a connecting plate 51. The connecting plate 51 has a waist-shaped groove 52. The opposite sides of the two connecting plates 51 are provided with upright plates fixedly installed on the base 1. Two symmetrical shafts 53 are rotatably installed on the upright plates. The right disk 40 and the right shaft 53 are connected by a spur gear set 54. The outer diameter of the spur gear on the shaft 53 is smaller than the outer diameter of the spur gear on the disk 40. The two shafts 53 are connected by an incomplete gear mechanism 55. The base 1 and the support plate 30 are jointly provided with a transmission component 56 for driving the left shaft 53 to rotate. The incomplete gear mechanism 55 is provided with a push-pull component 57 for driving the connecting plate 51 to move left and right.

[0049] like Figure 1 , Figure 2 and Figure 3As shown, the adjustment part 34 includes a sloping groove 340. The upper end of the pressure block 33 has two sloping grooves 340 that are inclined from left to right and back. The cover plate has a second waist groove that corresponds to the sloping groove 340. An electric telescopic rod 341 is fixedly installed on the upper end of the cover plate. A drive plate 342 is fixedly installed on the telescopic section of the electric telescopic rod 341. A roller 343 is fixedly installed on the lower end of the drive plate 342 at a position corresponding to the second waist groove. The roller 343 slides through the corresponding second waist groove into the corresponding sloping groove 340.

[0050] like Figure 1 and Figure 3 As shown, the execution unit 6 includes a rotating shaft 60. The upper end of the base 1 is rotatably mounted with the rotating shaft 60 located to the left of the left limiting mechanism 2 via a bearing seat. A second motor 61 with an output shaft fixedly connected to the rotating shaft 60 is fixedly mounted on the base 1. The disc 40 located on the left side and the rotating shaft 60 are both connected by a first belt pulley mechanism 62.

[0051] In operation, the transmission component 56 drives the left shaft 53 to rotate, and the left shaft 53 drives the right shaft 53 to rotate intermittently through the incomplete gear mechanism 55. The incomplete gear mechanism 55 also drives the connecting plate 51 to move back and forth through the push-pull component 57. The connecting plate 51 drives the U-shaped plate 31 to move back and forth through the support column 50. When the incomplete gear mechanism 55 drives the U-shaped plate 31 to move towards the rubber roller and squeezes the rubber roller through the pressure block 33, the right shaft 53 does not rotate, so the rubber roller remains stationary. When the incomplete gear mechanism 55 drives the U-shaped plate 31 away from the rubber roller, it drives the right shaft 53 to rotate through the incomplete gear mechanism 55. The right shaft 53 drives the disc 40 to rotate at a certain angle through the spur gear set 54. The disc 40 drives the fixed rubber roller to rotate at a certain angle. Since the outer diameters of the spur gears on the shaft 53 and the disc 40 are different, the rotation angle of the rubber roller can be reduced, thereby ensuring that the outer wall of the rubber section of the rubber roller can be fully squeezed.

[0052] The electric telescopic rod 341 pushes the drive plate 342 forward, and the drive plate 342 drives the pressure block 33 to move to the right through the cooperation of the roller shaft 343 and the inclined groove 340. This can change the force of the push-pull member 57 driving the U-shaped plate 31 to reciprocate and squeeze the rubber roller, thereby detecting the elastic performance of the rubber roller under different squeezing forces.

[0053] After the elasticity test is completed, the rubber roller is fixed to the limiting mechanism 2 on the left. Then, the push-pull component 57 drives the U-shaped plate 31 to move towards the rubber roller, so that the grinding block 32 contacts the rubber roller. Then, the second motor 61 drives the rotating shaft 60 to rotate. The rotating shaft 60 drives the disc 40 to rotate through the first belt pulley mechanism 62. The disc 40 drives the fixed rubber roller to rotate in order to perform the wear resistance test of the rubber roller. The distance that the push-pull component 57 pushes the U-shaped plate 31 towards the rubber roller can change the force of the grinding block 32 pressing the rubber roller, thereby testing the wear resistance of the rubber roller under different friction forces.

[0054] like Figure 3 , Figure 5 and Figure 6 As shown, the push-pull component 57 includes a guide post 570, and the incomplete gear mechanism 55 consists of a driving gear and a driven gear. The driving gear is fixedly installed on the left shaft 53, and the driven gear is fixedly installed on the right shaft 53. The guide post 570, which slides with the waist-shaped groove 52, is fixedly installed at the eccentric end of the driving gear away from the vertical plate.

[0055] like Figure 1 , Figure 3 and Figure 5 As shown, the transmission component 56 includes a third motor 560. The third motor 560 is fixedly installed on the upper end of the base 1 between the front upright plate and the front screw plate 451. The output shaft of the third motor 560 is fixedly installed with a drive rod 561 that rotates through the two support plates 30. The shaft 53 located on the left side is connected to the drive rod 561 through a second belt pulley mechanism 562.

[0056] In operation, motor 560 drives drive rod 561 to rotate, which in turn drives left shaft 53 to rotate via pulley mechanism 562. Left shaft 53 then drives the drive gear of incomplete gear mechanism 55 to rotate. The drive gear, through the engagement of guide post 570 and waist groove 52, drives connecting plate 51 to move back and forth. During the process of drive gear moving connecting plate 51 to the right to squeeze rubber roller, the toothless section of drive gear locks with driven gear. In the arc engagement, the driven gear does not rotate, meaning the rubber roller remains stationary. The pressure block 33 then squeezes the rubber roller. Meanwhile, the drive gear, through the engagement of the guide post 570 and the waist-shaped groove 52, drives the connecting plate 51 to move to the left away from the rubber roller. During this process, the toothed section of the drive gear meshes with the driven gear, causing the driven gear to rotate. The driven gear, through the shaft 53 and the spur gear set 54, drives the disc 40 to rotate at a certain angle. The disc 40 then drives the fixed rubber roller to rotate at a certain angle, thereby achieving comprehensive extrusion detection of the outer wall of the rubber section of the rubber roller.

[0057] After the rubber roller is fixed on the limiting mechanism 2 on the left, when the drive gear drives the connecting plate 51 to move to the left through the cooperation of the guide post 570 and the waist groove 52, it will drive the grinding block 32 to squeeze the rubber roller through the U-shaped plate 31 to test the wear resistance of the rubber roller.

[0058] In addition, the present invention also provides a flexible rubber roller detection method, which is completed with the assistance of a flexible rubber roller detection device, including the following steps: S1, the rubber roller is manually placed on the right limiting mechanism 2 so that both ends of the rubber roller are located in the corresponding arc plate 21, and then the rubber roller is fixed by the pushing member 45 and the squeezing member 44.

[0059] S2. The drive unit 5 drives the pressure block 33 to move back and forth. While the pressure block 33 is moving and squeezing the rubber roller, the rubber roller remains stationary. As the pressure block 33 moves away from the rubber roller, it drives the rubber roller to rotate at a certain angle to ensure that the outer wall of the rubber section of the rubber roller is fully squeezed for elasticity testing.

[0060] S3. Remove the rubber roller after elasticity testing, and check whether the elasticity is qualified by manual inspection or corresponding instrument. Then fix the rubber roller after elasticity testing onto the left limit mechanism 2.

[0061] S4. The actuator 6 drives the fixed rubber roller to rotate, and the drive unit 5 drives the grinding block 32 to contact the rubber roller to perform wear resistance testing. The drive unit 5 can change the distance the grinding block 32 moves, thereby changing the squeezing force of the grinding block 32 on the rubber roller, and thus the wear resistance of the rubber roller under different friction forces can be tested.

[0062] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.
