[0023] Specific examples are given below.

[0024] See also Figures 1-5 As shown, the utility model provides a rubber plate grinding and trimming equipment, including a base 1, a protective baffle 22 is installed on the top of the base 1, and installation grooves are respectively opened at both ends of the top of the protective baffle 22, and a third rotating shaft 17 and a fourth rotating shaft 18 are rotatably installed in the installation grooves, and the outer sides of the third rotating shaft 17 and the fourth rotating shaft 18 are equipped with conveying rollers, and the two conveying rollers are connected by a main conveyor belt 21; a No. 1 motor 2 is installed at the bottom of the base 1, and a No. 6 pulley 16 is installed on the rotating shaft of the No. 1 motor 2, and a No. 5 pulley 14 is installed at one end of the No. 3 rotating shaft 17, and the No. 5 pulley 14 and the No. 6 pulley 16 are connected by a No. 3 belt 15.

[0025] During operation, the fifth pulley 14 and the sixth pulley 16 are connected by a third belt drive. When the motor shaft of the first motor 2 installed on the base 1 rotates, it drives the rotation of the sixth pulley 16. While the sixth pulley 16 rotates, it drives the fifth pulley 14 to rotate synchronously. The rotation of the fifth pulley 14 drives the rotation of the third rotating shaft 17, and the conveying rollers assembled on the third rotating shaft 17 rotate, driving the operation of the main conveyor belt and realizing the feeding of the rubber plate.

[0026] The central rotating shaft 20 runs horizontally through the two protective baffles 22, and bearings are sleeved at the contact points between the central rotating shaft 20 and the protective baffles 22. One end of the central rotating shaft 20 is respectively installed with a second pulley 5 and a third pulley 6, and a first bevel gear is fixed at the other end of the central rotating shaft 20. The support plate fixes one side of the protective baffle 22; a vertical rotating shaft 13 is vertically and rotatably installed inside the protective baffle 22, a second bevel gear is fixed at the bottom end of the vertical rotating shaft 13, and a vertical grinding roller 131 is fixed at a position above the outer wall of the vertical rotating shaft 13.

[0027] During operation, in order to perform the edge trimming operation on the rubber plate, the rotation of the motor shaft of the second motor 10 drives the synchronous rotation of the first pulley 3 and the third pulley 6, driving the rotation of the central rotating shaft 20. One end of the central rotating shaft 20 is provided with a bevel gear, and the vertical rotating shaft 13 is driven to rotate synchronously through the bevel gear. When the rubber plate is fed, the side edge trimming operation can be performed.

[0028] Furthermore, a bevel gear is fixedly installed at one end of the central rotating shaft 20, and the vertical rotating shaft 13 and the central rotating shaft 20 perform synchronous operations through the bevel gear.

[0029] A second motor 10 is installed in the middle of the base 1. The output end of the second motor 10 is equipped with a first pulley 3. The first pulley 3 and the third pulley 6 are connected by a first belt 4. Two sets of rolling brackets are installed on the top side of the protective baffle 22. A first rotating shaft 9 and a second rotating shaft 11 are respectively rotatably installed on the two sets of rolling brackets; conveying rollers are installed on the first rotating shaft 9 and the second rotating shaft 11, and the two conveying rollers are connected by an auxiliary conveyor belt 12. One end of the first rotating shaft 9 is equipped with a fourth pulley 8, and the fourth pulley 8 and the second pulley 5 are connected by a second belt 7.

[0030] During operation, the rubber sheet grinding and trimming equipment is used for grinding and trimming rubber sheets. During the grinding process, the rubber sheet may deform due to heat. To avoid deformation, an auxiliary conveyor belt 12 is provided above the main conveyor belt. When processing the rubber sheet, the rotation of the motor shaft of the first motor 2 drives the synchronous rotation of the sixth pulley 16 and the fifth pulley 14, realizing the operation of the main conveyor belt 21 and the feeding of the rubber sheet. The rotation of the motor shaft of the second motor 10 drives the synchronous rotation of the first pulley 3 and the third pulley 6. The second pulley 5 and the fourth pulley 8 are connected by the second belt 7, and the synchronous rotation of the fourth pulley 8 and the second rotating shaft 11 realizes the transmission of the auxiliary conveyor belt 12. At the same time, since the auxiliary conveyor belt 12 is parallel to the main conveyor belt 21, it plays a good fixing role and can effectively prevent the rubber sheet from deforming due to heat during processing.

[0031] On the other side of the protective baffle 22, a fixing plate 191 is fixedly connected. On the top side of the fixing plate 191, a connecting rod 192 is fixed. At the top end of the connecting rod 192, a tightening cap is fixed. A screw rod is rotatably installed in the tightening cap. The end of the screw rod is rotatably connected to a fixing bracket 19. There is a gap between the bottom outer wall of the auxiliary conveyor belt 12 and the top outer wall of the main conveyor belt 21. The fixing bracket 19 is arranged in the gap. The vertical grinding roller 131 is arranged in the middle of the rotation direction of the auxiliary conveyor belt 12. The vertical grinding roller 131 is arranged parallel to the fixing bracket 19. During operation, the fixing bracket can prevent the rubber sheet from shifting during grinding.

[0032] Furthermore, a fixing bracket 19 is installed on the side of the protective baffle.

[0033] During operation, the rubber sheet is fixed by adjusting the fixing bracket 19 to prevent the rubber sheet from shifting during processing.

[0034] Working principle: To cooperate with the overall rubber plate grinding operation, the fifth pulley 14 and the sixth pulley 16 are connected by a third belt drive. The motor shaft of the first motor 2 installed on the base 1 rotates, driving the rotation of the sixth pulley 16. While the sixth pulley 16 rotates, it drives the fifth pulley 14 to rotate synchronously. The rotation of the fifth pulley 14 drives the rotation of the third rotating shaft 17. The conveying rollers assembled on the third rotating shaft 17 rotate, driving the operation of the main conveyor belt, realizing the feeding of the rubber plate. Through the rotation of the motor shaft of the second motor 10, it drives the synchronous rotation of the first pulley 3 and the third pulley 6, driving the rotation of the central rotating shaft 20. One end of the central rotating shaft 20 is provided with a bevel gear, which drives the vertical rotating shaft 13 to rotate synchronously through the bevel gear, performing the side trimming operation. An auxiliary conveyor belt 12 is arranged above the main conveyor belt. During the processing of the rubber plate, the rotation of the motor shaft of the first motor 2 drives the synchronous rotation of the sixth pulley 16 and the fifth pulley 14, realizing the operation of the main conveyor belt 21 and the feeding of the rubber plate. Through the rotation of the motor shaft of the second motor 10, it drives the synchronous rotation of the first pulley 3 and the third pulley 6. The second pulley 5 and the fourth pulley 8 are connected by a second belt 7. The synchronous rotation of the fourth pulley 8 and the second rotating shaft 11 realizes the drive of the auxiliary conveyor belt 12. At the same time, since the auxiliary conveyor belt 12 is parallel to the main conveyor belt 21, it avoids the deformation of the rubber plate during the processing. On the other side of the protection baffle 22, there is a fixed plate 191 fixedly connected. On the top side of the fixed plate 191, there is a connecting rod 192 fixedly installed. At the top end of the connecting rod 192, there is a tightening cap. A screw rod is rotatably installed in the tightening cap. The end of the screw rod is rotatably connected to a fixed bracket 19. The rubber plate is fixed by adjusting the fixed bracket 19.
