Technical Field
[0001] The utility model relates to the technical field of synthetic leather processing, in particular to a synthetic leather surplus material cutting device for battery back covers. Background Art
[0002] Most of the current battery back covers are made of synthetic leather. Compared with natural leather, synthetic leather is cheaper and usually has good wear resistance and tear resistance, which makes it very suitable for battery back covers and other parts that need to withstand daily use and wear. In addition, synthetic leather also has good weather resistance and chemical resistance, and can maintain stable performance under different environmental conditions.
[0003] Currently, in the production process of battery back covers, synthetic leather materials may produce waste materials due to size, shape or design requirements. Through cutting processing, these waste materials can be re-cut into pieces of suitable sizes, so that they can be reused in other parts of the production process or as raw materials for other products. However, the current waste cutting device for synthetic leather for battery back covers requires the staff to manually pull the synthetic leather for battery back covers every time after the device completes cutting, which consumes the staff's time and energy, reducing the work efficiency of the entire cutting process. Especially in the case of mass production, manual operation will significantly extend the production cycle, and manual operation may also cause uneven pulling speed of the synthetic leather, which may affect the cutting accuracy and product size consistency.

A fixed platform 7 is bolted to the bottom of the wall, and a plurality of clamping plates 8 are fixed to the surfaces on the right sides of the movable platform 6 and the fixed platform 7, and the positions of the clamping plates 8 on the upper and lower sides correspond to each other. An electric slide 9 is fixed to the surface on the right side of the mounting platform 4, and a cutting blade 10 is fixed to the front of the right side of the electric slide 9, a dust extraction structure 11 is fixed above the fixed frame 2, a movable frame 12 is provided on the left side above the cutting table 1, and a thumb cylinder 13 is fixed above the movable frame 12, and a positioning structure 14 is fixed to the front and rear sides below the cutting table 1.
[0023] The positioning structure 14 includes a mounting frame 141, a motor 142, a first timing pulley 143, a second timing pulley 144, a timing belt 145 and a connecting sleeve 146. The mounting frame 141 is fixed to the left and right sides of the front and rear sides of the bottom of the cutting table 1, the motor 142 is fixed inside the left mounting frame 141, the first timing pulley 143 is fixed to one end of the output shaft of the motor 142, the second timing pulley 144 is rotatably connected to one side of the right mounting frame 141, the timing belt 145 is sleeved on the surface of the first timing pulley 143 and the second timing pulley 144 and meshed with the first timing pulley 143 and the second timing pulley 144, the connecting sleeve 146 is fixed on the surface of the timing belt 145, and the connecting sleeve 146 is fixedly connected to the front and rear sides of the movable frame 12. Next, guide strips 15 are fixed on the front and rear sides of the cutting table 1, and guide blocks 16 are fixed on the surface of the opposite side of the connecting sleeve 146, and the guide strip 15 passes through the guide block 16 and is slidably connected with the guide block 16. When the thumb cylinder 13 clamps the synthetic leather of the battery back cover, the staff can turn on the motors 142 on both sides, thereby rotating the first timing pulley 143, and the first timing pulley 143 drives the second timing pulley 144 to rotate through the timing belt 145, and the timing belt 145 drives the connecting sleeve 146 on its surface to move, and the guide block 16 also slides on the surface of the guide strip 15, thereby guiding the connecting sleeve 146, so that the movable frame 12 moves smoothly to the right, and the synthetic leather of the battery back cover is stretched for subsequent cutting operations.
[0024] The dust extraction structure 11 includes a filter box 111, a dust pump 112, a fixing rod 113, a dust cover 114 and a vent pipe 115. The filter box 111 is fixed to the top of the fixing frame 2, and a filter screen is installed inside the filter box 111. The dust pump 112 is fixed to the right side of the filter box 111, and the dust pump 112 is connected to the filter box 111.

Then, the ventilation pipe 115 is connected to the right side of the dust suction pump 112, and the other end of the ventilation pipe 115 passes through the dust suction hood 114 and is connected to the dust suction hood 114. When the cutting blade 10 rotates to cut the synthetic leather of the battery back cover, the staff turns on the upper dust suction pump 112, so that the dust suction pump 112 sucks air through the ventilation pipe 115, and the dust suction hood 114 absorbs the dust generated by the cutting below. The dust enters the interior of the filter box 111 and is filtered by the filter net, and then the filtered air is discharged.
[0025] There are several thumb cylinders 13, and the positions of the thumb cylinders 13 and the left clamping plate 8 correspond to each other. Through the arrangement of multiple thumb cylinders 13, the staff can adapt when clamping the synthetic leather of battery back covers of different widths, which is convenient for subsequent cutting operations.
[0026] Grooves 17 are provided on both the front and rear sides of the top of the cutting table 1, and scale lines are set inside the grooves 17. When the staff is cutting the synthetic leather for the battery back cover, the setting of the scale lines can help the staff to accurately cut the synthetic leather and improve the processing accuracy.
[0027] Working principle: when the staff needs to cut the synthetic leather waste for the battery back cover, the staff first pulls the synthetic leather waste for the battery back cover wound on the surface of the winding roller 3, moves it to between the upper and lower clamping plates 8, and continues to pull it to the right, and then the staff turns on the motors 142 on both sides to move the movable frame 12 to the left, and the thumb cylinder 13 approaches the synthetic leather waste for the battery back cover. Then the staff turns on the thumb cylinder 13, and then the clamping claws of the thumb cylinder 13 contract, and then clamp the right side of the synthetic leather waste for the battery back cover. Then the staff continues to control the motor 142, and then the movable frame 12 moves to the right, and the synthetic leather waste for the battery back cover is stretched. After the synthetic leather waste for the battery back cover is stretched a certain distance, the staff can open the hydraulic cylinders 5 on both sides, and then the output shaft of the hydraulic cylinder 5 pushes the movement The table 6 descends and fixes the left side of the synthetic leather residue for the battery back cover by the clamping plates 8 on the upper and lower sides. At this time, the staff opens the cutting blade 10, and the cutting blade 10 rotates while the electric slide 9 starts to work. The electric slide 9 drives the cutting blade 10 to move backward, so that the cutting blade 10 cuts the synthetic leather residue for the battery back cover, and the dust suction pump 112 above is turned on to absorb the dust generated by the cutting. After the cutting is completed, the staff controls the thumb cylinder 13 to release the cut synthetic leather residue for the battery back cover, and the cut synthetic leather residue for the battery back cover falls on the top of the cutting table 1. Then the staff can remove the synthetic leather residue for the battery back cover, and repeat the above operation to continuously cut the synthetic leather residue for the battery back cover wound on the surface of the winding roller 3, so as to complete the cutting work of the synthetic leather residue for the battery back cover.
