[0042] High-efficiency roughing: This rubber roughing machine achieves continuous conveying and roughing of rubber sheets through the installation of feed rollers and a conveyor belt. The conveyor belt quickly transports the rubber sheets to the roughing area, where the diamond grinding rods rotate under the drive of the grinding rod motor, efficiently grinding the rubber sheets. This continuous conveying and grinding method greatly improves roughing efficiency. Compared with traditional manual roughing or single-sheet processing methods, it can significantly shorten processing time, increase production efficiency, and meet the needs of large-scale production.

[0043] Uniform coarsening: The pressure mechanism plays a crucial role in the coarsening process. The upper and lower pressure rollers apply pressure from the upper and lower surfaces of the rubber sheet, respectively, ensuring close contact between the rubber sheet and the diamond grinding rod. Simultaneously, the upper pressure roller rotates under the drive of its motor, moving synchronously with the diamond grinding rod, thus preventing uneven coarsening caused by relative slippage between the rubber sheet and the grinding rod. This double-sided pressure and synchronous rotation design ensures uniform force on the rubber sheet during coarsening, resulting in consistent coarsening effects and improving product quality and consistency.

[0055] 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 protection scope of the present utility model.

[0056] In this embodiment of the utility model, please refer to Figures 1 to 10 A rubber roughening machine, including a frame 22, and further including:

[0057] Display controller 23 is connected to rack 22;

[0058] The material feeding and lifting mechanism, connected to the frame 22, is used to lift the rubber sheet of the shoe sole placed on top of it;

[0059] The material handling mechanism, connected to the frame 22, is used to pick up and place the rubber sheet of the shoe sole on the material lifting mechanism;

[0060] The feed roller 3 is rotatably connected to the frame 22, and the feed roller 3 is provided in several sets;

[0061] Conveyor belt 17 is connected to feed roller 3;

[0062] One end of the chain drive component 4 is connected to a set of the feed rollers 3;

[0063] The feed motor 5 is connected to the frame 22, and its output end is connected to the other end of the chain drive component 4;

[0064] The grinding rod motor 14 is connected to the frame 22;

[0065] One end of the grinding rod belt 13 is connected to the output end of the grinding rod motor 14;

[0066] The diamond grinding rod 16 is connected to the other end of the grinding rod belt 13;

[0067] The pressurizing mechanism, connected to the frame 22, is used to pressurize the rubber sheet of the shoe sole.

[0068] Workers place the rubber sole sheet on the feeding and lifting mechanism, which lifts the sheet up. The material removal mechanism then removes the sheet from the feeding and lifting mechanism and places it on the conveyor belt 17. The feeding motor 5 starts, driving the feeding roller 3 to rotate via the chain drive 4, which in turn drives the conveyor belt 17. The conveyor belt 17 transports the rubber sheet to the roughing area. Simultaneously, the grinding rod motor 14 starts, driving the diamond grinding rod 16 to rotate via the grinding rod belt 13, thus grinding the rubber sole sheet. The pressure mechanism applies pressure to the rubber sole sheet during the grinding process to ensure the grinding effect.

[0069] As one embodiment of this utility model, please refer to Figure 1 , Figure 3 , Figure 4 , Figure 6 and Figure 7 The material feeding and lifting mechanism includes:

[0070] The mounting plate 24 is connected to the frame 22;

[0071] Limiting rod 2 is connected to fixing plate 24;

[0072] The feeding rack motor 1 is connected to the fixed plate 24;

[0073] The threaded rod 25 is connected to the output end of the feeding rack motor 1 and is rotatably connected to the fixed plate 24;

[0074] Sliding block 26 is threadedly connected to threaded rod 25;

[0075] The sliding rod 27 is connected to the fixed plate 24, passes through the sliding block 26, and is slidably connected to it;

[0076] The feeding plate 15 is connected to the sliding block 26 and is used to support the material.

[0077] The operator places the rubber sheet of the shoe sole on the feeding plate 15. The feeding rack motor 1 starts and drives the threaded rod 25 to rotate. The threaded connection between the threaded rod 25 and the sliding block 26 causes the sliding block 26 to move upward along the axis of the threaded rod 25. The sliding rod 27 guides the movement of the sliding block 26. As the sliding block 26 moves upward, it drives the feeding plate 15 to rise, raising the rubber sheet to a suitable height for the material picking mechanism to pick up the material. The limit rod 2 blocks and limits the rubber sheet of the shoe sole to ensure that the rubber sheet does not move and fall.

[0078] As one embodiment of this utility model, please refer to Figures 1 to 4 , Figure 8 The material handling mechanism includes:

[0079] Feeding cylinder 8 is connected to frame 22;

[0080] The suction cylinder 7 is connected to the feeding cylinder 8;

[0081] The suction plate 6 is connected to the suction cylinder 7.

[0082] When the feeding cylinder 8 is activated, it pushes the suction cylinder 7 to move above the discharge plate 15 in the set direction. The suction cylinder 7 descends, causing the suction disc 6 to contact the surface of the rubber sheet and adhere to it. Then, the suction cylinder 7 rises, causing the rubber sheet to leave the discharge plate 15. The feeding cylinder 8 is activated again, moving the suction disc 6 above the conveyor belt 17. The suction cylinder 7 descends, placing the rubber sheet onto the conveyor belt 17, thus completing the material picking and placement process.

[0083] As one embodiment of this utility model, please refer to Figures 2 to 5 , Figures 8 to 10 The pressurization mechanism includes:

[0084] The upper pressure roller cylinder 10 is connected to the frame 22;

[0085] The sliding plate 28 is slidably connected to the frame 22 and connected to the upper pressure roller cylinder 10;

[0086] The upper pressure roller 11 is rotatably connected to the sliding plate 28, and the upper pressure roller 11 is located at the top of the diamond grinding rod 16;

[0087] The upper pressure roller motor 9 is connected to the frame 22;

[0088] The telescopic universal joint 21 is connected at one end to the output end of the upper pressure wheel motor 9 and at the other end to the upper pressure wheel 11;

[0089] The pressure roller cylinder 20 is connected to the frame 22;

[0090] The lower pressure wheel plate 19 is connected to the lower pressure wheel cylinder 20;

[0091] The lower pressure roller 18 is rotatably connected to the lower pressure roller plate 19 and is located at the bottom of the upper pressure roller 11.

[0092] When the rubber sheet enters the roughing area, the upper pressure roller cylinder 10 and the lower pressure roller cylinder 20 respectively push the upper pressure roller 11 and the lower pressure roller 18 closer to the rubber sheet, apply pressure to the upper and lower surfaces of the rubber sheet, so that the rubber sheet is in close contact with the diamond grinding rod 16. The upper pressure roller motor 9 drives the upper pressure roller 11 to rotate through the telescopic universal joint 21, which drives the rubber sheet to move, completing the entire roughing process.

[0093] As one embodiment of this utility model, please refer to Figure 2 , Figure 4 , Figure 8 and Figure 9 It also includes:

[0094] The discharge plate 12 is connected to the frame 22 and is inclined. The discharge plate 12 is located on the side of the diamond grinding rod 16 away from the conveyor belt 17.

[0095] After roughening, the rubber sheet falls onto the discharge plate 12. Due to the inclined setting of the discharge plate 12, the rubber sheet slides out of the equipment along the discharge plate 12 under its own gravity, completing the entire rubber roughening operation process.

[0096] The working principle of this utility model is as follows: The operator places the rubber sheet of the shoe sole on the feeding plate 15. The feeding rack motor 1 starts, driving the threaded rod 25 to rotate. The threaded connection between the threaded rod 25 and the sliding block 26 causes the sliding block 26 to move upward along the axial direction of the threaded rod 25. The sliding rod 27 guides the movement of the sliding block 26. As the sliding block 26 moves upward, it drives the feeding plate 15 to rise, raising the rubber sheet to a suitable height. The feeding cylinder 8 starts, pushing the suction cylinder 7 to move above the feeding plate 15 in a set direction. The suction cylinder 7 descends, causing the suction disc 6 to contact the rubber sheet. The rubber sheet is adsorbed onto the surface of the rubber sheet. Then, the suction cylinder 7 rises, driving the rubber sheet away from the discharge plate 15. The feeding cylinder 8 starts again, moving the suction plate 6 above the conveyor belt 17. The suction cylinder 7 descends, placing the rubber sheet onto the conveyor belt 17, completing the material picking and placement process. The feeding motor 5 starts, driving the feeding roller 3 to rotate through the chain drive component 4, thereby driving the conveyor belt 17 to run. The conveyor belt 17 transports the rubber sheet to the roughing area. At the same time, the grinding rod motor 14 starts, driving the diamond grinding rod 16 to rotate through the grinding rod belt 13, grinding the rubber sheet of the shoe sole.

[0097] When the rubber sheet enters the roughing area, the upper pressure roller cylinder 10 and the lower pressure roller cylinder 20 respectively push the upper pressure roller 11 and the lower pressure roller 18 closer to the rubber sheet, apply pressure to the upper and lower surfaces of the rubber sheet, so that the rubber sheet is in close contact with the diamond grinding rod 16. The upper pressure roller motor 9 drives the upper pressure roller 11 to rotate through the telescopic universal joint 21, which drives the rubber sheet to move, completing the entire roughing process.

[0098] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
