[0020] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.
[0021] Reference Figures 1 to 4 As shown, a cutting machine for producing rubber cups comprises a cutting machine body 1, a conveying crawler 2 installed in the cutting machine body 1, and a plurality of bowl-shaped object blocks 4 arranged on the crawler plate of the conveying crawler 2, and a trimming mechanism is arranged above the cutting machine body 1;
[0022] The trimming mechanism includes a support block 3 arranged in a porch shape above the conveyor crawler 2 and a motor 5 installed at the center of the top surface of the support block 3. The output shaft of the motor 5 rotates and penetrates into the support block 3 and is fixed with a cylinder 6. A turntable 11 is fixed to the end of the push rod of the cylinder 6. A cutter 12 is fixed to the edge of the bottom surface of the turntable 11, and the end of the cutter 12 points to the edge of the top surface of the object block 4.
[0023] By setting up the trimming mechanism, the leather cups can be placed one by one on the object block 4, and the cutting machine body 1 and the conveyor belt 2 can be started. The leather cups on the object block 4 can be conveyed to the bottom of the turntable 11 by using the conveyor belt 2. Then, the cylinder 6 can be started, and the turntable 11 and the cutter 12 can be driven down by the push rod of the cylinder 6. Then, the end of the cutter 12 can be abutted against the edge of the leather cup. The motor 5 can be started, and the output shaft can be used to drive the cylinder 6 and the turntable 11 to rotate, so that the cutter 12 can follow the rotation and cut the edge of the leather cup through the end. In this way, the cutting of the edge of the leather cup can be completed.
[0024] However, in practice, when the cutting machine is cutting the leather cup, since the corners of the leather cup cannot be guaranteed to be in the same horizontal plane, when the end of the turntable 11 presses the leather cup lip and cuts, the other side of the leather cup often rises, and the cutting roundness of the leather cup lip cannot be guaranteed.
[0025] In view of this, in order to solve the above problem, a pressing mechanism is provided above the object block 4 for pressing and fixing the edges when cutting the corners of the leather cup.
[0026] The edge pressing mechanism includes an edge pressing ring 15 annularly arranged between the object block 4 and the rotating disk 11, a limiting block 8 slidably sleeved on the push rod of the cylinder 6, and a lower pressing block 9 arranged above the limiting block 8. The lower pressing block 9 is annular and rotatably sleeved on the push rod of the cylinder 6. The lower pressing block 9 is provided with fixed blocks 7 on both the upper and lower sides. The fixed block 7 is tightly sleeved on the push rod of the cylinder 6. A large spring 10 is fixed between the lower pressing block 9 and the limiting block 8. A plurality of support columns 16 are fixed between the limiting block 8 and the edge pressing ring 15. The two ends of the limiting block 8 are slidably connected to the inner wall of the support block 3.
[0027] By setting the edge pressing mechanism, when the cylinder 6 is started, the fixed block 7 on the push rod of the cylinder 6 is used to drive the pressing block 9 to descend, and the limiting block 8 is driven to descend together through the large spring 10, and the limiting block 8 is used to drive the turntable 11 and the support column 16 to descend synchronously, and then the edge pressing ring 15 is lowered until the leather cup corner on the object block 4 is pressed. As the push rod of the cylinder 6 continues to descend, the pressing block 9 continuously compresses the large spring 10 until the turntable 11 at the end of the push rod of the cylinder 6 drives the end of the cutter 12 to collide with the leather cup corner on the object block 4, so that the edge pressing ring 15 can be used to press the edge before the cutter 12 cuts the leather cup corner, thereby solving the problem in the prior art that when the trimming knife cuts the rubber leather cup corner, there is no edge pressing mechanism to press the leather cup lip, causing the trimming knife to vibrate when cutting the rubber leather cup, resulting in burrs on the leather cup corner after cutting.
[0028] By slidingly connecting the two ends of the limiting block 8 with the inner wall of the object block 4, the moving trajectory of the limiting block 8, the pressing block 9 and the large spring 10 can be limited, preventing the pressing block 9 or the limiting block 8 from rotating synchronously when the motor 5 drives the push rod of the cylinder 6 to rotate.
[0029] However, after using it for a period of time, it was found that the heat generated by the cutter 12 when cutting the corners of the leather cup caused the corners of the leather cup to soften and become sticky, and the edge pressing ring 15 kept pressing the corners of the leather cup, causing the corners of the leather cup to stick to the bottom of the edge pressing ring 15. After the edge pressing ring 15 finished pressing the corners and was driven up by the push rod of the cylinder 6, the corners of the leather cup were often lifted up, which was not conducive to the subsequent continuous pressing of the leather cup.
[0030] Further, refer to Figure 2 and Figure 4As shown, it is worth noting that a vertical groove is vertically provided in the support column 16, a separation component is provided in the vertical groove, a support ring 14 matching with the separation component is provided above the pressure ring 15, and a fixing rod 13 is fixed between the support ring 14 and the inner side of the support block 3;
[0031] The separation component includes a separation rod 19 slidably connected to the inner wall of the vertical groove and a connecting rod 18 arranged on the side of the support column 16 away from the center of the pressure ring 15. A rectangular groove 17 is opened on the inner wall of the support column 16 away from the center of the pressure ring 15. One end of the connecting rod 18 slides into the rectangular groove 17 and is fixed to the separation rod 19. The bottom surface of the rod body at the other end of the connecting rod 18 is against the pressure ring 15. One end of the separation rod 19 slides through the pressure ring 15. A small spring 20 is fixed to the other end of the separation rod 19, and the end of the small spring 20 is fixed to the top surface of the inner wall of the vertical groove.
[0032] By setting the separation component, during the descent of the edge pressure ring 15, the small spring 20 in the support column 16 drives the separation rod 19 and the connecting rod 18 to descend together. When descending a certain distance, the connecting rod 18 abuts against the support ring 14. When the support column 16 continues to descend, the connecting rod 18 drives the separation rod 19 to remain in this position and compress the small spring 20, so that the end of the separation rod 19 retracts into the edge pressure ring 15. When the edge pressure ring 15 presses the edge corner of the leather cup, the end of the separation rod 19 does not contact the edge corner of the leather cup, thereby avoiding During the softening process of the leather cup corner, it adheres to the end of the separation rod 19. When the push rod of the fixed block 7 drives the support column 16 and the pressure ring 15 to rise, the separation rod 19 is acted upon by the reverse elastic force of the small spring 20, pushing the connecting rod 18 on one side of the separation rod 19 to continue to maintain the contact with the support ring 14. During this process, the separation rod 19 gradually extends out from the pressure ring 15 and contacts the leather cup corner adhered to the bottom of the pressure ring 15 until the leather cup corner is pushed away from the bottom of the pressure ring 15, so that the leather cup corner falls back on the object block 4.
