Description

Technical Field

[0001] This utility model relates to the field of pad testing technology, specifically to an industrial pad abrasion resistance testing device. Background Technology

[0002] Industrial mats are commonly used in various industrial applications, such as machinery, automotive, and electronics, as materials for protection, support, or isolation. Due to the complex and varied environments in which they are used, high requirements are placed on their abrasion resistance. The quality of abrasion resistance directly affects the service life and effectiveness of the industrial mat.

[0003] A search revealed a utility model patent with Chinese patent publication number CN109142033A, which discloses an industrial fabric abrasion resistance testing device. The device includes a base, a fixed support on the base, a slide rail on the upper end of the base, a stepper motor mounted on the slide rail, the stepper motor moving along the slide rail, a movable support above the stepper motor, fabric clamps on both the fixed support and the movable support, a friction wheel above the base, and a rotating motor at the center of the friction wheel.

[0004] The aforementioned device uses a motor to drive the rubber layer on the outside of the friction wheel to generate friction. As a result, the rubber layer is subjected to considerable friction. With the increase in usage time, the rubber layer inevitably needs to be replaced. However, in order to ensure that the rubber layer can function effectively, the rubber layer and the friction wheel also need to be sufficiently secure, which will lead to the problem of inconvenient replacement and there is room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide an industrial pad abrasion resistance testing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an industrial pad abrasion resistance testing device, comprising a worktable and a support frame, wherein the worktable is located at the top of the support frame, a friction assembly is installed inside the support frame, the friction assembly includes a rotating roller rotatably connected inside the support frame, the rotating roller is horizontally arranged, a plurality of equally spaced limiting grooves are formed on the outer circumference of the rotating roller, a movable plate is slidably inserted into each of the plurality of limiting grooves, a pressing plate is fixedly connected to the ends of the plurality of movable plates that are far apart from each other, a rubber sleeve is slidably fitted on the outside of the plurality of pressing plates, and a motor is fixedly installed on the outer wall of one end of the support frame, the output end of the motor being coaxially fixed with one end of the rotating roller.

[0007] As a further preferred embodiment of this technical solution, a drive ring is rotatably connected to the outer wall of one end of the rotating roller. The outer wall of the drive ring is provided with multiple round-headed protrusions. An extension block is fixedly connected to the outer wall of one end of each of the multiple moving plates. The drive ring can push the multiple extension blocks outward.

[0008] As a further preferred embodiment of this technical solution, an extension ring is fixedly connected to the outer circumference of the drive ring, a positioning rod is slidably inserted inside the extension ring, a spring is sleeved on the outside of the positioning rod, the two ends of the spring are fixedly connected to the end of the positioning rod and the extension ring respectively, and a corresponding locking hole is opened on the outer wall of one end of the rotating roller.

[0009] When replacement is needed, a large gap is created between the rubber sleeve and the drive roller. Pulling one end of the positioning rod outward removes the restriction on the drive ring. Then, by moving the drive ring, the external protrusions stop pressing on the extension block, and consequently, the moving plate and the pressing plate stop pressing on the inner wall of the rubber sleeve. The rubber sleeve is no longer restricted and can be easily replaced. After completion, the drive ring is moved in the opposite direction, and its external protrusions push the extension block outward. This causes the moving plate and the pressing plate to move away from each other and tightly press on the inner wall of the rubber sleeve, ensuring that it will not slip during use. When the positioning rod moves to the locking hole position set outside the rotating roller, the spring will drive the positioning rod to insert into the locking hole, and the position of the drive ring will be fixed.

[0010] As a further preferred embodiment of this technical solution, a transmission assembly is installed inside the workbench. The transmission assembly includes a reciprocating lead screw rotatably connected inside the workbench. The reciprocating lead screw forms a transmission engagement with the support frame. Two limiting rods are fixedly connected inside the workbench. The support frame is slidably sleeved on the outside of the two limiting rods. A second motor is fixedly installed inside the workbench. The output end of the second motor is coaxially fixed with one end of the reciprocating lead screw.

[0011] When the second motor inside the workbench is started, its output drives the reciprocating screw to start rotating. The support frame, which is restricted by the limit rod, will move back and forth under the drive of the reciprocating screw, so that the area of ​​the fabric subjected to friction is larger, allowing more positions to be tested, which is beneficial to increase the test effect and makes it easier to observe the results.

[0012] As a further preferred embodiment of this technical solution, the top outer wall of the workbench is fixedly connected to two fixing frames, which are respectively located on both sides of the support frame. Each of the two fixing frames has a slot on its top outer wall, and a clamping plate is slidably inserted into each slot. The clamping plate is threadedly connected to the fixing frame by two bolts.

[0013] As a further preferred embodiment of this technical solution, the drive ring and the plurality of extension blocks are all made of magnets.

[0014] As a further preferred embodiment of this technical solution, the support frame consists of two parts: a vertical plate and an L-plate, which are connected by bolts.

[0015] This utility model provides a device for testing the abrasion resistance of industrial pads, which has the following advantages:

[0016] (1) By setting a friction component, this utility model can create a large gap between the rubber sleeve and the transmission roller when replacement is required, which facilitates the replacement work. It can also firmly fix the rubber sleeve during operation and prevent slippage. Pull one end of the positioning rod outward so that the drive ring is no longer restricted. Then, move the drive ring so that the external protrusion no longer squeezes the extension block. As a result, the moving plate and the pressing plate no longer squeeze the inner wall of the rubber sleeve. The rubber sleeve will no longer be restricted and can be easily replaced. After completion, move the drive ring in the opposite direction so that the external protrusion can push the extension block to move outward. As a result, the moving plate and the pressing plate will move away from each other and tightly squeeze the inner wall of the rubber sleeve to ensure that it will not slip during use. When the positioning rod moves to the position of the locking hole set outside the rotating roller, the spring will drive the positioning rod to insert into the locking hole, and the position of the drive ring will also be fixed.

[0017] (2) By setting up a transmission component, the second motor inside the workbench is started, and its output end drives the reciprocating screw to start rotating. The support frame, which is limited by the limit rod, will move back and forth under the drive of the reciprocating screw, so that the area of ​​the cloth being rubbed is larger, and more positions can be tested, which is conducive to increasing the test effect and making it easier to observe the results.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0024] The utility model provides a technical solution: Figure 2 , Figure 3 and Figure 4 As shown in this embodiment, an industrial pad abrasion resistance testing device includes a worktable 1 and a support frame 5. The worktable 1 is located at the top of the support frame 5. A friction assembly 6 is installed inside the support frame 5. The friction assembly 6 includes a rotating roller 601 rotatably connected inside the support frame 5. The rotating roller 601 is horizontally arranged. Multiple equally spaced limiting grooves 602 are opened on the outer circumference of the rotating roller 601. A movable plate 603 is slidably inserted into each of the multiple limiting grooves 602. A pressing plate 604 is fixedly connected to the ends of the multiple movable plates 603 that are far apart from each other. Rubber sleeves 611 are slidably fitted on the outside of the multiple pressing plates 604. A motor 610 is fixedly installed on the outer wall of one end of the support frame 5. The output end of the motor 610 is coaxially fixed with one end of the rotating roller 601.

[0025] A drive ring 605 is rotatably connected to the outer wall of one end of the rotating roller 601. The outer wall of the drive ring 605 is provided with multiple round-headed protrusions. An extension block 606 is fixedly connected to the outer wall of one end of each of the multiple moving plates 603. The drive ring 605 can push the multiple extension blocks 606 outward.

[0026] An extension ring 607 is fixedly connected to the outer circumference of the drive ring 605. A positioning rod 608 is slidably inserted inside the extension ring 607. A spring 609 is sleeved on the outside of the positioning rod 608. The two ends of the spring 609 are fixedly connected to the end of the positioning rod 608 and the extension ring 607, respectively. A corresponding locking hole is opened on the outer wall of one end of the rotating roller 601.

[0027] Start the motor 610 outside the support frame 5. Its output drives the rotating roller 601 and the rubber sleeve 611 to rotate, thus initiating friction operation. If the rubber sleeve 611 needs to be replaced, remove the vertical plate on the side of the support frame 5, pull one end of the positioning rod 608 outward, so that the drive ring 605 is no longer restricted. Then, move the drive ring 605 so that its external protrusion no longer presses against the extension block 606. Consequently, the moving plate 603 and the pressing plate 604 no longer press against the inner wall of the rubber sleeve 611, and the rubber sleeve 611 will... No longer restricted, replacement can be easily performed. After completion, the drive ring 605 is reversed, and its external protrusions push the extension block 606 to move outward. As a result, the moving plate 603 and the pressing plate 604 will move away from each other and tightly press the inner wall of the rubber sleeve 611 to ensure that it will not slip during use. When the positioning rod 608 moves to the position of the locking hole set outside the rotating roller 601, the spring 609 will drive the positioning rod 608 to insert into the locking hole, and the position of the drive ring 605 will also be fixed.

[0028] like Figure 1 and Figure 2 As shown, a transmission assembly 7 is installed inside the workbench 1. The transmission assembly 7 includes a reciprocating lead screw 701 rotatably connected inside the workbench 1. The reciprocating lead screw 701 and the support frame 5 form a transmission engagement. Two limit rods 702 are fixedly connected inside the workbench 1. The support frame 5 is slidably sleeved on the outside of the two limit rods 702. A second motor 703 is fixedly installed inside the workbench 1. The output end of the second motor 703 is coaxially fixed with one end of the reciprocating lead screw 701.

[0029] When the motor 703 inside the workbench 1 is started, its output drives the reciprocating screw 701 to start rotating. The support frame 5, which is limited by the limit rod 702, will move back and forth under the drive of the reciprocating screw 701, so that the area of ​​the fabric subjected to friction is larger, and more positions can be tested, which is conducive to increasing the test effect and making it easier to observe the results.

[0030] like Figure 1 and Figure 2 As shown, two fixed brackets 2 are fixedly connected to the top outer wall of the workbench 1. The two fixed brackets 2 are located on both sides of the support frame 5. The top outer wall of the two fixed brackets 2 is provided with a slot, and a clamping plate 3 is slidably inserted into each slot. Two bolts 4 are threadedly connected between the clamping plate 3 and the fixed bracket 2.

[0031] After removing one of the clamps 3, place one end of the fabric on top of the fixing frame 2, and then reinsert the clamp 3 into the groove on top of the fixing frame 2. Then use bolt 4 to fix the clamp 3 to the fixing frame 2, thereby fixing one end of the fabric. After tightening the fabric, repeat the operation to fix the other end of the fabric so that subsequent work can proceed smoothly.

[0032] like Figure 4 As shown, the drive ring 605 and the multiple extension blocks 606 are all made of magnets. When the rubber sleeve 611 is removed, the drive ring 605 can fix the extension blocks 606, thereby preventing the compression plate 604 and the moving plate 603 from coming out of the limiting groove 602.

[0033] like Figure 1 and Figure 2 As shown, the support frame 5 consists of two parts: a vertical plate and an L-plate, which are connected by bolts, allowing for easy assembly and disassembly. This ensures that one end of the transmission roller 601 is unrestricted, facilitating the replacement of the rubber sleeve 611.

[0034] This utility model provides a device for testing the abrasion resistance of industrial pads, the specific working principle of which is as follows:

[0035] When the device is in operation, after removing one clamp 3, place one end of the fabric on top of the fixed frame 2, and then reinsert the clamp 3 into the groove on top of the fixed frame 2. Then, use bolt 4 to fix the clamp 3 to the fixed frame 2, thus securing one end of the fabric. After tightening the fabric, repeat the operation to secure the other end of the fabric to facilitate subsequent work. Start the motor 610 outside the support frame 5, whose output drives the rotating roller 601 and rubber sleeve 611 to rotate, thus initiating the friction operation. Then, start the motor 703 inside the worktable 1, whose output drives the reciprocating screw 701 to rotate. The support frame 5, limited by the limit rod 702, will move back and forth under the drive of the reciprocating screw 701, increasing the area of ​​the fabric subjected to friction and allowing for testing at more locations, which is beneficial for improving testing effectiveness and facilitating operation. According to the observation results, if the rubber sleeve 611 needs to be replaced, after removing the vertical plate on the side of the support frame 5, pull one end of the positioning rod 608 outward so that the drive ring 605 is no longer restricted. Then, move the drive ring 605 so that its external protrusion no longer presses the extension block 606. As a result, the moving plate 603 and the pressing plate 604 no longer press the inner wall of the rubber sleeve 611. The rubber sleeve 611 will no longer be restricted and can be easily replaced. After completion, move the drive ring 605 in the opposite direction. Its external protrusion can push the extension block 606 to move outward. As a result, the moving plate 603 and the pressing plate 604 will move away from each other and tightly press the inner wall of the rubber sleeve 611 to ensure that it will not slip during use. When the positioning rod 608 moves to the position of the locking hole set outside the rotating roller 601, the spring 609 will drive the positioning rod 608 to insert into the locking hole, and the position of the drive ring 605 will also be fixed.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
