Description

Technical Field

[0001] This utility model relates to the technical field of leather waste recycling equipment, specifically a leather production grinding device with double-sided grinding function. Background Technology

[0002] In the process of leather waste recycling, leather production grinding equipment with double-sided grinding function can re-grind the recycled leather waste to restore its surface quality, thereby realizing the reuse of leather waste, reducing the waste of leather resources, and increasing economic value.

[0003] In the process of using a leather production grinding device with double-sided grinding function, leather waste needs to be placed on the upper end of the conveyor. Then, the distance between the two sets of grinding rollers is adjusted by the cooperation of gears and racks to make them contact the upper and lower surfaces of the leather waste. The conveyor then moves the leather waste, while the drive device rotates the grinding rollers. The two sets of grinding rollers rotate in opposite directions. Finally, the grinding rollers grind the leather waste.

[0004] Existing leather production grinding devices with double-sided grinding function can adjust the distance between the two grinding rollers through the cooperation of gears and racks. However, some grinding rollers are quite heavy, and over time, the tooth surfaces of the gears and racks will be damaged. Damaged tooth surfaces lead to unstable meshing of the gears and racks, reducing the adjustment accuracy and the stability of the grinding rollers, ultimately affecting the grinding quality. Therefore, we propose a leather production grinding device with double-sided grinding function. Utility Model Content

The rear ends of the transmission plates 76 are rotatably connected to the front ends of the vertically adjacent push plates 72. Adjustment mechanism 7 also includes... The system includes a protective cover 74, a screw 77, and a drive motor 78. The protective cover 74 is located at the front end of the machine body 1. The screw 77 is rotatably connected to the middle of the right wall of the protective cover 74. The adjusting seat 75 is threaded to the middle of the outer arc surface of the screw 77 through a threaded hole located at the middle of its right end. The drive motor 78 is located at the middle of the right end of the protective cover 74. The left end of the output shaft of the drive motor 78 is fixedly connected to the right end of the screw 77. The input end of the drive motor 78 is electrically connected to the output end of the control switch group 2. Through the cooperation of the push plate 72 and the fixed rod 73, the distance between the two sets of grinding rollers 6 can be adjusted, which optimizes the adjustment method, can withstand greater impact force and load, solves the problem of reduced adjustment accuracy due to damage to the tooth surface of the gear and rack plate, prevents damage to the grinding rollers 6, and ensures grinding quality.

[0023] It also includes a control switch group 2, which is located at the front end of the machine body 1. The input end of the control switch group 2 is electrically connected to an external power supply and can regulate the electrical components inside the equipment.

[0024] The system also includes motors 8, which are all located in the middle of the rear end of the fixed base 5. The front end of the output shaft of motor 8 is fixedly connected to the rear end of the longitudinally adjacent grinding rollers 6. The input end of motor 8 is electrically connected to the output end of the control switch group 2. By controlling the control switch group 2, motor 8 starts to run. The output shaft of motor 8 drives the grinding rollers 6 to rotate. The two sets of motors 8 rotate in opposite directions, so that the upper and lower surfaces of the leather waste are ground by the grinding rollers 6.

[0025] The machine body 1 has the following components: Conveyor roller 1 (9) rotatably connected to the left side of the interior, with adjacent conveyor rollers 1 (9) connected via conveyor belt 1.

The upper ends of the four uprights 3 are slidably connected to the corresponding sliding holes provided on the lower end of the connecting plate 4.

The connecting plate 4 will drive the grinding roller 6 to move along the uprights 3 through the fixed seat 5.

[0027] The working principle of the leather production grinding device with double-sided grinding function provided by this utility model is as follows: Before use, the leather waste to be ground is placed on the upper end of conveyor belt one and conveyor belt two. Then, by controlling the switch group 2, the drive motor 78 starts running. The output shaft of the drive motor 78 drives the screw 77 to rotate. During the rotation of the screw 77, it drives the adjusting seat 75 to move to the right through the threaded connection. During the movement of the adjusting seat 75 to the right, it applies a pulling force to the push plate 72 through the transmission plate 76, thereby causing the push plate 72 to rotate around the mounting rod 71. At this time, the fixed rod 73 slides inside the limiting groove and rotates relative to the limiting groove, thereby causing the push plate 72 to drive the connecting plate 4 to move through the fixed rod 73. The connecting plate 4 then drives the grinding roller 6 to move along the upright rod 3 through the fixed seat 5. At this time, the distance between the two grinding rollers 6 will gradually decrease. Finally, the outer arc surfaces of the two sets of polishing rollers 6 are brought into contact with the upper and lower surfaces of the leather waste. At this time, the motor 8 starts running by controlling the switch group 2. The output shaft of the motor 8 drives the polishing rollers 6 to rotate. The two sets of motors 8 rotate in opposite directions. At the same time, the conveyor motor 11 and the conveyor motor 212 start running by controlling the switch group 2. The output shaft of the conveyor motor 11 drives the left conveyor roller 9 to rotate. The left conveyor roller 9 drives the right conveyor roller 9 to rotate via the conveyor belt 1. The output shaft of the conveyor motor 212 drives the right conveyor roller 210 to rotate. The right conveyor roller 210 drives the left conveyor roller 210 to rotate via the conveyor belt 2. The conveyor motors 11 and 212 rotate in the same direction, thereby moving the leather waste to the right. During the movement, the polishing rollers 6 polish the upper and lower surfaces of the leather waste.

[0028] It is worth noting that the drive motor 78 and motor 8 disclosed in the above embodiments can be ECMA-C20604RS, the first conveyor motor 11 and the second conveyor motor 12 can be 5I K200A-AF, and the control switch group 2 is provided with control buttons corresponding to the drive motor 78, motor 8, the first conveyor motor 11 and the second conveyor motor 12 for controlling their switches.
