DETAILED DESCRIPTION

[0024] 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.

[0025] Example 1: Please refer to Figure 1-6 The utility model provides a technical solution: a packaging machine cutter mechanism adjustment device, including a blister packaging machine 1; four support rods 2 are symmetrically fixedly installed on the blister packaging machine 1, and the same support plate 3 is fixedly installed on the four support rods 2. A switching frame 4 is slidably installed on the bottom side of the support plate 3, and a cutter switching structure is installed on the switching frame 4. A cylinder 5 is fixedly installed on the top side of the support plate 3. The output end of the cylinder 5 passes through the support plate 3 and is fixedly installed with a push plate 6. The push plate 6 is movably installed on the switching frame 4. Two U-shaped positioning rods 7 are fixedly installed on both sides of the switching frame 4. The four U-shaped positioning rods 7 are installed with positioning structures. A plurality of adjusting screws 8 are installed on the cutter switching structure, and an adjusting structure is installed on the adjusting screw 8;

[0026] The cutter switching structure includes two mounting plates 41, and the two mounting plates 41 are movably mounted on the bottom side of the switching frame 4. The inner walls of the two mounting plates 41 are provided with adjustment grooves 410, and a plurality of connecting sliders 42 are slidably mounted in the two adjusting grooves 410. A connecting seat 43 is fixedly mounted on one side of the connecting slider 42, and a blister tray cutter 44 is movably mounted on one side of the connecting seat 43. Four mounting screws 45 are threadedly mounted on the blister tray cutter 44, and one end of the four mounting screws 45 are threadedly mounted on the connecting seat 43. A plurality of guide slide bars 46 are fixedly mounted on one side of the two mounting plates 41, and a limit slide bar 47 is fixedly mounted on one end of the guide slide bar 46. The limit slide bar 47 is slidably mounted on the inner wall of the switching frame 4. Two connecting holes 412 are provided on the switching frame 4, and the push plate 6 corresponds to one of the connecting holes 412. The two connecting holes 412 correspond to the two mounting plates 41 respectively.

[0027] The positioning structure includes two positioning bolts 71, and the two positioning bolts 71 are threadedly installed on the U-shaped positioning rod 7. Two positioning holes 72 are provided on the support rod 2, and the two positioning bolts 71 are respectively matched with the two positioning holes 72. When the blister tray moves to the bottom of the switching frame 4, the cylinder 5 can be turned on, and the output end of the cylinder 5 will push the push plate 6 to move downward, so that the moving push plate 6 pushes the corresponding mounting plate 41 to move. When the mounting plate 41 moves, it will drive the blister tray cutter 44 to move downward to cut the blister tray to separate it. When the cylinder 5 drives the push plate 6 to move upward and reset, the spring 49 will push the limit slider 47 to move upward and reset, thereby driving the blister tray cutter 44 to separate from the blister tray. When the blister tray cutter 44 is worn and damaged and needs to be replaced, the positioning bolt 71 connected to the support rod 2 can be unscrewed from the U-shaped positioning rod 7, and then the switching frame 4 is pushed to switch. The frame 4 can drive the mounting plate 41 with the damaged blister tray cutter 44 to move out from under the support plate 3, and move the mounting plate 41 equipped with the normal blister tray cutter 44 to under the support plate 3, so as to complete the rapid switching of different mounting plates 41 and different blister tray cutters 44. At this time, when the cylinder 5 is turned on, it will drive the push plate 6 to squeeze another mounting plate 41 and make its corresponding blister tray cutter 44 descend for cutting operation, and will not cause interference to the removed mounting plate 41 during the process. At this time, the staff can unscrew the mounting screw 45 on the damaged blister tray cutter 44 from the corresponding connecting seat 43, remove the blister tray cutter 44 from the connecting seat 43 for replacement, and by respectively installing blister tray cutters 44 of different shapes on the two mounting plates 41, the two mounting plates 41 can be quickly switched to meet the cutting of blister trays of different shapes, saving tool changing time.

[0028] The limit slider 47 is then driven by the guide rod 46 to move and reset, so that the mounting plate 41 drives the blister tray cutter 44 to separate from the blister tray.

[0029] In order to limit the moving direction of the switching frame 4 and avoid the position of the switching frame 4 being offset when switching different mounting plates 41, two T-shaped guide grooves 413 are provided on the support plate 3, and T-shaped guide blocks 411 are slidably installed in the two T-shaped guide grooves 413. The two T-shaped guide blocks 411 are fixedly installed on the top side of the switching frame 4. When the switching frame 4 moves, the two T-shaped guide blocks 411 will be driven to slide in the two T-shaped guide grooves 413 respectively.

[0030] The working principle is as follows: when the blister tray moves to the bottom of the switching frame 4, the cylinder 5 can be turned on, and the output end of the cylinder 5 will push the push plate 6 to move downward, so that the moving push plate 6 passes through the corresponding connecting hole 412 and pushes the corresponding mounting plate 41 to move. When the mounting plate 41 moves, it will drive the corresponding guide slide bar 46 and the limit slide block 47 to move. The moving limit slide block 47 will slide in the limit slide groove 48 and squeeze the spring 49, thereby limiting the moving direction of the guide slide bar 46, the limit slide block 47 and the mounting plate 41. The continuously moving mounting plate 41 will drive the connecting seat 43 to move through the connecting slide block 42, so that the moving connecting seat 43 drives the blister tray cutter 44 to move downward, and finally the downward moving blister tray cutter 44 cuts the blister tray. When the cylinder 5 drives the push plate 6 to move upward and reset, the spring 49 in the compressed state will be released and push the limit slider 47 to move upward and reset. The reset limit slider 47 will drive the mounting plate 41 to move and reset through the guide slide bar 46, so that the mounting plate 41 drives the blister tray cutter 44 to separate from the blister tray. When the blister tray cutter 44 is worn and damaged and needs to be replaced, the positioning bolt 71 connected to the support rod 2 can be unscrewed from the U-shaped positioning rod 7 to release the connection restriction between the support rod 2 and the U-shaped positioning rod 7, thereby releasing the restriction on the switching frame 4, and then pushing the switching frame 4. When the switching frame 4 moves, it will drive the two T-shaped guide blocks 411 to slide in the two T-shaped guide grooves 413 respectively, avoiding the switching frame 4 The displacement occurs, so that the switching frame 4 can drive the mounting plate 41 with the damaged blister tray cutter 44 to move out from under the supporting plate 3, and move the mounting plate 41 equipped with the normal blister tray cutter 44 to under the supporting plate 3, and at the same time drive the two U-shaped positioning rods 7 on the other side to move, and finally make the other two U-shaped positioning rods 7 respectively sleeved on the other two supporting rods 2, and then screw the positioning bolts 71 into the corresponding U-shaped positioning rods 7 and the positioning holes 72, and re-fix the position of the switching frame 4, so as to complete the rapid switching of different mounting plates 41 and different blister tray cutters 44. At this time, when the cylinder 5 is turned on, the cylinder 5 will drive the push plate 6 to squeeze another mounting plate 41 and make the corresponding blister tray cutter 44 descend to perform the cutting operation, and the process The removed mounting plate 41 will not be disturbed. At this time, the staff can unscrew the mounting screw 45 on the damaged blister tray cutter 44 from the corresponding connecting seat 43, and remove the blister tray cutter 44 from the connecting seat 43 to replace the blister tray cutter 44. By installing blister tray cutters 44 of different shapes on the two mounting plates 41, the two mounting plates 41 can be quickly switched to meet the cutting of blister trays of different shapes, saving tool change time. The adjusting screw 8 can be driven to rotate by rotating the knob 81. The rotating adjusting screw 8 will rotate and move in the adjusting screw hole 84 on the connecting slider 42. The moving adjusting screw 8 will drive the positioning plug 82 to move out of the corresponding positioning slot 83.At this time, the restriction on the connecting slider 42 can be released, and the adjusting screw 8 can be driven to move horizontally by pushing the knob 81 horizontally. The horizontally moving adjusting screw 8 will drive the connecting slider 42 to slide horizontally in the adjusting slot 410, and the sliding connecting slider 42 will drive the blister tray cutter 44 to move horizontally through the connecting seat 43, so that the distance between two adjacent blister tray cutters 44 can be adjusted according to the size of the blister tray or the required distance.

[0031] Example 2: Figure 3-5 In order to improve the applicability of the device, the blister tray cutter 44 can be adjusted according to the cutting spacing required for the blister tray, so an adjustment structure is arranged on the adjustment screw 8, and the adjustment structure includes a knob 81 and a positioning plug 82. The knob 81 and the positioning plug 82 are fixedly installed at both ends of the adjustment screw 8 respectively, and the adjustment screw 8 is threadedly installed on the connecting slider 42. The positioning plug 82 is movably installed on the inner wall of the adjustment groove 410. The inner wall of the adjustment groove 410 is provided with a plurality of positioning slots 83. The positioning plug 82 is movably installed in a corresponding one of the positioning slots 83. The inner wall of the connecting slider 42 is provided with an adjusting screw hole 84.

At this time, the restriction on the connecting slider 42 can be released, and the adjusting screw 8 can be driven to move horizontally by pushing the knob 81 horizontally. The horizontally moving adjusting screw 8 will drive the connecting slider 42 to slide horizontally in the adjusting groove 410, and the sliding connecting slider 42 will drive the blister tray cutter 44 to move horizontally through the connecting seat 43, so that the distance between two adjacent blister tray cutters 44 can be adjusted so as to be adjusted according to the size of the blister tray or the required distance. The remaining features are the same as those in Example 1.
