Description

Technical Field

[0001] This utility model relates to the field of tire testing machine technology, specifically a device for conveniently replacing the surface sandpaper of a tire testing machine. Background Technology

[0002] With the development of tire technology, more and more types of finished tire testing machines have emerged in the tire testing industry. Many finished tire testing machines require different sandpapers to simulate different road surfaces. Since the sandpapers have different grit numbers, they need to be replaced frequently.

[0003] Traditionally, disassembly requires two people. First, a hot air gun is used to soften the adhesive on the sandpaper before forcefully tearing it off the surface. Reassembly also requires two people: one slowly lays the sandpaper flat on the testing machine surface and pulls it straight, while the other uses a roller to gently roll it over the flattened sandpaper. This two-person process wastes manpower, and after removal, a lot of adhesive residue remains, requiring time-consuming and labor-intensive cleaning.

[0004] Based on this, a device is now provided for conveniently replacing the surface sandpaper of a tire testing machine, which can eliminate the drawbacks of existing devices. Utility Model Content

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] In one embodiment, such as Figures 1-8 As shown, a device for conveniently changing the surface sandpaper of a tire testing machine includes a frame 100. Two axles 101 are rotatably connected to the lower end of the frame 100. Wheels 102 are fixedly connected to both ends of each axle 101. A rotating shaft 103 is rotatably connected to the frame 100. A roller 200 is fixedly connected to the outer end of the rotating shaft 103. The frame 100 is equipped with a transmission mechanism for driving the roller 200 to rotate. The frame 100 also includes a flattening component for spreading the sandpaper and a component to prevent adhesive adhesion. The spraying module has a fixing component on the roller 200 for fixing sandpaper. One end of the sandpaper is fixed to the roller 200 by the fixing component. When removing the sandpaper, the frame 100 is moved, the wheel 102 rotates, the wheel 102 drives the axle 101 to rotate, and the axle 101 drives the roller 200 to rotate through the transmission mechanism, so that the sandpaper is slowly wrapped around the roller 200. The spraying module reduces the stickiness of the sandpaper and avoids leaving adhesive residue on the road surface. When attaching the sandpaper, the flattening component flattens the sandpaper.

[0029] In this embodiment, as Figure 4 and Figure 5As shown, the transmission mechanism includes a first bevel gear 301, which is fixedly connected to the outer end of the axle 101. The first bevel gear 301 meshes with a second bevel gear 302, which is fixedly connected to one end of a transmission shaft 303. The other end of the transmission shaft 303 is fixedly connected to a third bevel gear 304, which meshes with a fourth bevel gear 305 and a fifth bevel gear 306. The fourth bevel gear 305 and the fifth bevel gear 306 are symmetrically arranged on both sides of the third bevel gear 304. The fourth bevel gear 305 and the fifth bevel gear 306 are fixedly connected to the outer end of a rotating block 307. The two rotating blocks 307 are rotatably connected to the outer end of the rotating shaft 103 and rotatably connected to a U-shaped fixing frame 308. The U-shaped fixing frame 308 is fixedly connected to the frame 100. The U-shaped fixing frame 308 is equipped with an adjustment unit for adjusting the forward and reverse rotation of the roller 200. When the frame 100 is moved, the wheel 102 rotates, the wheel 102 drives the axle 101 to rotate, the axle 101 drives the first bevel gear 301 to rotate, the first bevel gear 301 drives the second bevel gear 302 to rotate, the second bevel gear 302 drives the drive shaft 303 to rotate, the drive shaft 303 drives the third bevel gear 304 to rotate, the third bevel gear 304 drives the fourth bevel gear 305 and the fifth bevel gear 306 to rotate. The rotation directions of the fourth bevel gear 305 and the fifth bevel gear 306 are opposite. The adjustment unit connects the fourth bevel gear 305 and the fifth bevel gear 306 to the rotating shaft 103 respectively, so that the rotation direction of the roller 200 is different when connected to different bevel gears.

[0030] In one embodiment, such as Figures 5-7As shown, the adjustment unit includes a rotating sleeve 401, which is slidably connected to the outer end of the rotating shaft 103 via a limiting pin. The rotating sleeve 401 is located between bevel gear 4 305 and bevel gear 5 306. The outer end of the rotating sleeve 401 is slidably connected to a rotating sleeve 402, and the outer end of the rotating sleeve 402 is rotatably connected to a U-shaped connecting frame 403. A sliding sleeve 404 is fixedly connected to the U-shaped connecting frame 403, and a swing rod is slidably connected in the sliding sleeve 404. 405, the swing rod 405 is rotatably connected to the U-shaped fixing frame 308, the rotating sleeve 401 is fixedly connected to the limiting block 406, the rotating block 307 is provided with a limiting groove 411 corresponding to the limiting block 406, the U-shaped fixing frame 308 is fixedly connected to the fixing block 407, the fixing block 407 is provided with two slots 408, the slots 408 are slidably connected to the locking blocks 409, the slots 408 are provided with springs 410, one end of the springs 410 is... The spring 410 is fixedly connected to the locking block 409, and the other end of the spring 410 is fixedly connected to the locking groove 408. Rotating the swing rod 405 causes the sliding sleeve 404 to rotate, which in turn causes the rotating sleeve 401 to slide along the rotating shaft 103. When removing sandpaper, the limiting block 406 engages with the limiting groove 411 connected to the bevel gear 405, thereby driving the roller 200 to rotate. When applying sandpaper, the swing rod 405 is rotated in the opposite direction, causing the limiting block 406 to engage with the bevel gear 405. The limiting groove 411 connected to the five-shaped gear 306 engages, thereby causing the roller 200 to rotate in the opposite direction. When the swing rod 405 is rotated, the swing rod 405 will press the locking block 409, causing the locking block 409 to retract into the locking groove 408 and compress the spring 410. When it moves into position, the locking block 409 resets under the action of the spring 410, limiting the swing rod 405 so that the swing rod 405 cannot rotate in the opposite direction, ensuring the stability of the connection between the limiting block 406 and the limiting groove 411.

[0031] In one embodiment, such as Figure 2 As shown, the paving component includes two fixing rods 501, which are fixedly connected to the frame 100. A flattening cylinder 502 is fixedly connected between the two fixing rods 501. When paving sandpaper, the flattening cylinder 502 rolls the paved sandpaper and fixes it to the road surface.

[0032] In one embodiment, such as Figure 2As shown, the spraying module includes a water spray pipe 601, which is fixedly connected to a fixed rod 501 by two fixing rods 605. The water spray pipe 601 is equipped with a spray head 602. The water spray pipe 601 is connected to the outlet of a water pump 606 via a water pipe. The inlet of the water pump 606 is connected to the outlet of a water tank 603. The water tank 603 is fixedly connected to the frame 100. The upper end of the water tank 603 is equipped with a feeding port 604. Adhesive remover is added to the water tank 603 through the feeding port 604. The water pump 606 draws the adhesive remover from the water tank 603 into the water spray pipe 601 and sprays it onto the joint between the sandpaper and the ground through the spray head 602, reducing the stickiness of the sandpaper and preventing residual adhesive from being left on the road surface.

[0033] In one embodiment, such as Figure 8 As shown, the fixing component includes a pressure block 701, and the roller 200 is provided with a groove 702. The pressure block 701 is slidably connected in the groove 702. The pressure block 701 is threadedly connected to a bolt 703, and the bolt 703 is threadedly connected to the roller 200. One end of the sandpaper is placed in the groove 702, and the bolt 703 is rotated to reduce the distance between the pressure block 701 and the groove 702, thereby pressing and fixing the sandpaper.

[0034] In one embodiment, such as Figure 1 and Figure 2 As shown, a limiting shaft 801 is rotatably connected between the two fixed rods 605, and a limiting shaft 802 is rotatably connected on the frame 100. The limiting shaft 802 is located at the lower end of the roller 200. When applying sandpaper, the limiting shaft 801 contacts the sandpaper, and when removing sandpaper, the limiting shaft 802 contacts the sandpaper, making the application and removal process smoother.

[0035] In one embodiment, such as Figure 1 As shown, a handle 900 is fixedly connected to the frame 100. The frame 100 can be pulled by the handle 900 to facilitate the movement of the device by the staff.

[0036] The above embodiment discloses a device for conveniently replacing the surface sandpaper of a tire testing machine. When removing the sandpaper, one end of the sandpaper is placed in the groove 702, and the bolt 703 is rotated to reduce the distance between the pressure block 701 and the groove 702, thus clamping and fixing one end of the sandpaper. The frame 100 is moved, the wheel 102 rotates, the wheel 102 drives the axle 101 to rotate, the axle 101 drives the first bevel gear 301 to rotate, the first bevel gear 301 drives the second bevel gear 302 to rotate, the second bevel gear 302 drives the drive shaft 303 to rotate, and the drive shaft 303 drives the third bevel gear 304 to rotate. The bevel gear 304 drives the bevel gear 405 and bevel gear 5 306 to rotate, rotating the swing rod 405. The swing rod 405 drives the sliding sleeve 404 to rotate, and the sliding sleeve 404 drives the rotating sleeve 401 to slide along the rotating shaft 103, so that the limiting block 406 is engaged with the limiting groove 411 connected to the bevel gear 405, driving the roller 200 to rotate, so that the sandpaper is slowly wrapped around the roller 200. The water pump 606 draws the adhesive remover in the water tank 603 into the water spray pipe 601, and sprays it onto the connection between the sandpaper and the ground through the water spray head 602, reducing the stickiness of the sandpaper and preventing residual adhesive from being left on the road surface.

[0037] When applying sandpaper, the swing arm 405 is rotated in the opposite direction to engage the limiting block 406 with the limiting groove 411 connected to the bevel gear 306. As the frame 100 moves, the roller 200 rotates in the opposite direction to slowly release the sandpaper, flatten the sandpaper laid flat by the roller 502, and fix the sandpaper to the road surface.

[0038] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
