DETAILED DESCRIPTION

[0032] The application will be further described in detail below with reference to the accompanying drawings.

[0033] The application discloses a cutting device for blister tray. Figure 1 The cutting device comprises a cutting frame 1. In the embodiment, the cutting frame 1 comprises a base 2 and four columns 3 vertically and fixedly installed at the top surface of the base 2 at four corner positions. A lifting die seat 4 is slidably and sleeved on the four columns 3, and the cutting tool 5 is fixedly installed on the bottom surface of the lifting die seat 4.

[0034] Referring to Figure 1 and Figure 2 The top end of each column 3 is provided with a screw transmission element 6. In the embodiment, the screw transmission element 6 comprises a screw shaft 61 and a screw nut 62. The screw shaft 61 is fixedly installed at the top end of the column 3 and coaxially arranged with the column 3. The screw nut 62 is threadedly sleeved on the circumference of the screw shaft 61. A movable seat 7 is collectively sleeved on the circumferential periphery of the plurality of screw nuts 62, and each screw nut 62 is rotationally connected with the movable seat 7. A plurality of connecting plates 8 are bolted on the side wall of the movable seat 7, and the end of each connecting plate 8 away from the movable seat 7 is bolted with the lifting die seat 4. The top surface of the movable seat 7 is provided with a driving mechanism.

[0035] Referring to Figure 1 and Figure 3The driving mechanism includes a drive motor 10 fixedly mounted on the top surface of the movable seat 7. A first transmission box 11 is also fixed on the top surface of the movable seat 7, and the output end of the drive motor 10 is inserted into the first transmission box 11. A first transmission rod 12 is rotatably passed through the first transmission box 11, and the first transmission rod 12 is perpendicular to the output end of the drive motor 10. A second transmission box 13 is fixed at both ends of the first transmission rod 12 on the top surface of the movable seat 7. A second transmission rod 14 is rotatably passed through each second transmission box 13, and the second transmission rod 14 is perpendicular to the first transmission rod 12. A first transmission assembly 15 is provided in both the first transmission box 11 and the second transmission box 13, and a second transmission assembly 16 is provided at both ends of the second transmission rod 14.

[0036] Reference Figure 3 and Figure 4 The first transmission assembly 15 located in the first transmission box 11 includes a transmission worm gear 151 and a transmission worm 152. The transmission worm 152 is coaxially fixedly connected to the output end of the drive motor 10 and located in the first transmission box 11. The transmission worm gear 151 is fixedly sleeved on the circumferential direction of the first transmission rod 12 and located in the first transmission box 11. The transmission worm gear 151 and the transmission worm 152 mesh with each other.

[0037] Reference Figure 3 and Figure 4 The drive motor 10 rotates, causing the transmission worm gear 152 located in the first transmission box 11 to rotate synchronously, thereby causing the transmission worm wheel 151 and the first transmission rod 12 located in the first transmission box 11 to rotate synchronously. While the first transmission rod 12 is rotating, it drives the second transmission rod 14 to rotate through the transmission worm gear 152 and the transmission worm wheel 151 located in the second transmission box 13.

[0038] Reference Figure 2 and Figure 3 The second transmission assembly 16 includes a first bevel gear 161 and a second bevel gear 162. The first bevel gear 161 is fixedly sleeved on the circumferential direction of the second transmission rod 14, and the second bevel gear 162 is fixedly installed on the top surface of the lead screw nut 62, and the first bevel gear 161 and the second bevel gear 162 mesh with each other.

[0039] Reference Figure 2 and Figure 3 When the second transmission rod 14 rotates, it drives the first bevel gear 161 to rotate synchronously, thereby driving the second bevel gear 162 and the lead screw nut 62 to rotate. This helps the lead screw nut 62 to move downward along the length of the lead screw shaft 61, which in turn helps the movable seat 7 to move downward, and further helps the lifting mold seat 4 and the cutting tool 5 to move downward synchronously through the connecting plate 8.

[0040] Reference Figure 1 and Figure 5A stop assembly 9 is provided on each of the four columns 3. The stop assembly 9 includes a fixed mold base 91, a stop seat 92, a stop plate 93, a guide rod 94, and a return spring 95. The fixed mold base 91 is fixedly sleeved on the circumferential periphery of the four columns 3. The fixed mold base 91 is spaced apart from the lifting mold base 4 and located below the lifting mold base 4. The stop seat 92 is fixedly installed on the top surface of the fixed mold base 91. An annular mounting groove 921 is opened on the top surface of the stop seat 92. The bottom end of the return spring 95 is fixedly connected to the mounting groove 921 and sleeved on the circumferential periphery of the column 3. The stop plate 93 is fixedly connected to the top end of the return spring 95 and sleeved on the circumferential periphery of the column 3. The top end of the guide rod 94 is fixedly installed on the bottom surface of the stop plate 93 and the bottom end of the guide rod 94 is slidably inserted into the stop seat 92. An annular placement groove 931 is provided on the top surface of the stop plate 93. A buffer block 17 is inserted into the placement groove 931, and the height of the buffer block 17 is greater than the depth of the placement groove 931.

[0041] Reference Figure 1 and Figure 5 During the downward movement of the lifting mold base 4 and the cutting blade 5, the lifting mold base 4 will gradually come into contact with the stop plate 93 and drive the stop plate 93 to move down synchronously. When the stop plate 93 comes into contact with the stop seat 92, the stop plate 93 and the stop seat 92 will block the lifting mold base 4 from moving down further, that is, to stop the lifting mold base 4 and the cutting blade 5, thereby helping to improve the accuracy of the downward position of the cutting blade 5, and thus helping to improve the accuracy of the cutting position of the blister tray, ensuring the cutting effect of the blister tray.

[0042] Reference Figure 5 The buffer block 17 helps to cushion the contact between the stop plate 93 and the lifting mold base 4. The placement groove 931 helps the buffer block 17 to retract into the placement groove 931 when squeezed, thereby helping the bottom surface of the lifting mold base 4 to contact the top surface of the stop plate 93, thus helping to improve the accuracy of the stopping position of the lifting mold base 4.

[0043] Reference Figure 1 A support base 18 is fixedly installed on the top surface of the fixed mold base 91. A cutting groove 19 is provided on the top surface of the support base 18, and the cutting groove 19 is located directly below the cutting tool 5.

[0044] Reference Figure 1 During the downward movement of the cutting blade 5, the cutting groove 19 facilitates the insertion of the cutting blade 5, and the support base 18 helps to support the blister tray with cutting, thereby helping to prevent the blister tray from deforming during the cutting process, and thus helping to improve the cutting effect of the blister tray.

[0045] The implementation principle of this application embodiment is as follows: the drive motor 10 runs, which drives the transmission worm gear 152 located in the first transmission box 11 to rotate synchronously, thereby driving the transmission worm wheel 151 and the first transmission rod 12 located in the first transmission box 11 to rotate synchronously. While the first transmission rod 12 is rotating, it drives the second transmission rod 14 to rotate through the transmission worm gear 152 and the transmission worm wheel 151 located in the second transmission box 13.

[0046] When the second transmission rod 14 rotates, it drives the first bevel gear 161 to rotate synchronously, thereby driving the second bevel gear 162 and the lead screw nut 62 to rotate. This helps the lead screw nut 62 to move downward along the length of the lead screw shaft 61, which in turn helps the movable seat 7 to move downward, and further helps the lifting mold seat 4 and the cutting tool 5 to move downward synchronously through the connecting plate 8.

[0047] As the lifting mold base 4 and the cutting blade 5 move downwards, the lifting mold base 4 gradually comes into contact with the stop plate 93 and drives the stop plate 93 to move downwards synchronously. When the stop plate 93 comes into contact with the stop seat 92, the stop plate 93 and the stop seat 92 will block the lifting mold base 4 from moving downwards further, that is, they will stop the lifting mold base 4 and the cutting blade 5. This will help improve the accuracy of the downward position of the cutting blade 5, and thus help improve the accuracy of the cutting position of the blister tray, ensuring the cutting effect of the blister tray.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
