[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a cutting device for producing blister parts, including a processing table 1, a support frame 2 is fixedly connected to the top of the processing table 1, a motor 3 is fixedly connected to the top of the support frame 2, two threaded rods 5 are rotatably connected to the inner top of the support frame 2, two threaded blocks 6 are externally threadedly connected to the threaded rods 5, a connecting rod 7 is rotatably connected to the bottom of the threaded block 6, a pressing plate 8 is rotatably connected to the other ends of the two connecting rods 7, one end of one of the threaded rods 5 is fixedly connected to a pulley 1 4, and one end of the other threaded rod 5 is fixedly connected to a pulley 2 12, a hydraulic cylinder 9 is fixedly connected to the top of the support frame 2, and a fixed block 10 is fixedly connected to the output end of the hydraulic cylinder 9, and a cutting tool 11 is installed inside the fixed block 10 through a clamping assembly 13.

[0024] Specifically, the support frame 2 is fixed by the processing table 1, so that the support frame 2 is more stable, and then the motor 3 is fixed by the support frame 2, so that the motor 3 is more stable during operation, ensuring the normal operation of the device, and the motor 3 drives the pulley 1 4 to rotate, so that one of the threaded rods 5 can rotate, and at the same time, the belt drives the pulley 2 12 to rotate, so that the other threaded rod 5 rotates, and then the two threaded blocks 6 connected to the outside of the threaded rod 5 move to both ends, and the connecting rod 7 is pushed to rotate by the threaded block 6, so that the pressing plate 8 moves downward, so that the two sides of the blister can be pressed and fixed to prevent it from sliding during cutting, thereby causing the cutting accuracy to deviate, affecting the final product quality, and the hydraulic cylinder 9 pushes the fixed block 10 to move downward, so that the cutting tool 11 can cut the blister.

[0025] Reference Figure 3 and Figure 4 , the clamping assembly 13 includes two limiting grooves 1301, which are arranged on the left and right sides of the interior of the fixed block 10, a slider 1302 is slidably connected to one side of the interior of the limiting groove 1301, a spring 1303 is fixedly connected to one side of the slider 1302, a push rod 1305 is fixedly connected to the other side of the slider 1302, a telescopic rod 1304 is rotatably connected to the outside of the slider 1302, and a clamping block 1306 is rotatably connected to the other end of the telescopic rod 1304, and a clamping groove 1307 is arranged on both sides of the cutting tool 11; the other end of the spring 1303 is fixedly connected to the inner wall of the limiting groove 1301, and the outer part of the spring 1303 is slidably connected to the inner wall of the limiting groove 1301; the longitudinal section of the clamping block 1306 is set to be square, and the clamping block 1306 is plug-in matched with the clamping groove 1307; one end of the push rod 1305 passes through the outer wall of the cutting tool 11, and the outer part of the push rod 1305 is slidably connected to the inside of the cutting tool 11.

[0026] Specifically, by pushing the push rods 1305 on both sides of the fixed block 10, the slider 1302 can be pushed to slide on one side of the inner side of the limiting groove 1301, so that the spring 1303 is compressed to shrink, thereby causing one end of the telescopic rod 1304 to rotate, and the other end of the telescopic rod 1304 drives the block 1306 to disengage from the slot 1307. At this time, the cutting tool 11 is removed and a new one is placed, and then the push rod 1305 is released, so that the spring 1303 begins to recover, thereby pushing the slider 1302 to move, and finally the block 1306 is separated from the slot 1307. 07 completes the plug-in fit to achieve the fixation of the cutting tool 11. The tool is installed on the fixed block 10 through the clamping assembly 13, which is convenient for disassembly of the tool, thereby reducing the maintenance cost of the later use of the device and being faster during replacement, reducing losses. The limiting groove 1301 can limit the movement of the slider 1302 and the spring 1303 to ensure the normal operation of the structure. The longitudinal section of the clamping block 1306 is set to a square, which can make it more firmly engaged with the clamping groove 1307, thereby achieving the fixation of the cutting tool 11.

[0027] Reference Figure 1 and Figure 2 Two electric slide rails 14 are installed on both sides of the top of the processing table 1, and support plates 15 are installed on the top of the two electric slide rails 14; the output end of the motor 3 is fixedly connected to the outside of the pulley 1 4, and the pulley 1 4 and the pulley 2 12 are connected by a belt; the left and right threads on the outer side of the threaded rod 5 are symmetrically arranged, and the two threaded blocks 6 are symmetrically arranged.

[0028] Specifically, the electric slide rail 14 can drive the support plate 15 to move, and the blister pieces to be cut can be sent to the bottom of the cutting tool 11, which reduces the labor intensity of the workers and reduces the occurrence of dangerous accidents. The belt can be used to rotate the pulley 14 when the pulley 12 is rotated, and the outer thread of the threaded rod 5 is set to be symmetrical on the left and right, so that the pressure plates 8 on both sides can be lowered at the same time, ensuring the stable effect of fixing the blister pieces.

[0029] Working principle: When using this device, first place the blister to be cut on the support plate 15, push it under the cutting tool 11 through the electric slide rail 14, then start the motor 3, and drive the pulley 1 4 to rotate through the motor 3, so that the threaded rod 5 rotates, and at the same time, the pulley 1 4 rotates the pulley 2 12 through the belt, so that the other threaded rod 5 rotates, so that the two threaded blocks 6 connected to the threaded rod 5 move toward both ends, and push the pressure plate 8 downward through the connecting rod 7, so as to achieve the pressing and fixing of both sides of the blister, avoiding the sliding of the blister during cutting, resulting in a decrease in cutting accuracy and poor quality of the produced blister, then start the hydraulic cylinder 9 to push the fixed block 10 downward, and finally complete the cutting of the blister through the cutting tool 11, so as to facilitate subsequent use.

[0030] If the cutting tool 11 needs to be replaced, the push rods 1305 on both sides of the fixed block 10 can be pressed, and the slider 1302 can be pushed to slide on one side of the inner side of the limiting groove 1301 through the push rods 1305, and pressure is applied to the spring 1303 to shrink it, thereby causing one end of the telescopic rod 1304 to rotate, and the other end of the telescopic rod 1304 can be used to drive the clamping block 1306 to disengage from the clamping groove 1307. At this time, the cutting tool 11 can be removed from the fixed block 10 for replacement. The cutting tool 11 is fixed by clamping, which is convenient for disassembly, reducing the maintenance cost of the device during use and improving production efficiency.
