The mounting frame 9 is provided with a rotary lifting press 10 for pressing and fixing the storage box 24 on the placement plate 52, and the rotary lifting press 10 includes a motor 101 installed on the top surface of the mounting frame 9, and the motor 101 is connected to the motor 101. An electric push rod 102 is installed on the output shaft of 01, a pressure block 103 is connected to the push rod of the electric push rod 102, a rotating ring 104 is installed on the outer shell of the electric push rod 102, an annular slide groove for guiding the rotation of the rotating ring 104 is opened on the mounting frame 9, a profiling plate 11 is connected to the bottom of the rotating ring 104 by bolts, the shape and size of the profiling plate 11 are consistent with the storage box 24, the profiling plate 11 is opened with a through hole matching the electric push rod 102, a slide groove is opened on the front side of the top surface of the mounting frame 9, a slider is slidably connected in the slide groove, a contact plate 12 located on the front side of the profiling plate 11 is connected to the bottom of the slider, a support spring 13 is connected between the contact plate 12 and the mounting frame 9, and is used to drive the contact plate 12 to keep in contact with the profiling plate 11,The contact plate 12 is rotatably connected to a contact wheel 19 at the rear side, and the friction between the contact plate 12 and the profiling plate 11 can be reduced by the contact wheel 19 to reduce the wear of the contact plate 12 and the profiling plate 11, thereby extending the service life of the contact plate 12 and the profiling plate 11. The contact plate 12 is connected to two upper and lower guide sleeves 15 through a height adjustment component 2. A connecting rod 16 is slidably arranged in the guide sleeve 15. A cutter 17 for cutting off the flash 26 is connected to the rear end of the connecting rod 16. A fastening bolt 18 for locking the connecting rod 16 is arranged at the top of the guide sleeve 15. An infrared sensor 41 is arranged between the bottom of the mounting plate 4 and the bottom of the workbench 2. The transmitter of the infrared sensor 41 is installed in the middle of the bottom of the mounting plate 4. The receiver of the infrared sensor 41 is installed at the bottom of the workbench 2. The receiver of the infrared sensor 41 is located directly below the profiling plate 11.

[0031] First, loosen the locking bolt 58 to unlock the sliding block 54, then move the sliding block 54, and pull the positioning plate 56 to move through the compression spring 57 to adjust the position of the positioning plate 56 to adapt to plastic storage boxes 24 of different sizes, and tighten the locking bolt 58 to re-lock the sliding block 54. Then, the plastic storage box 24 is turned upside down on the placement plate 52, and the plastic storage box 24 pushes the positioning plate 56 to move inward to compress the compression spring 57. Through the cooperation of the surrounding positioning plates 56 and the compression spring 57, the plastic storage box 24 can not only be centered, but also supported and fixed on the placement plate 52. Then, the electric slide rail 3 is controlled to drive the mounting plate 4 to drive the rotating placement table 5 to move leftward, thereby driving the plastic storage box 24 to move leftward. When the plastic storage box 24 contacts the inclined rod 83, the plastic storage box 24 continues to push the inclined rod 83 upward to the left, so that the U-shaped block 81 drives the V-shaped cutting knife 82 and the lifting block 75 to move upward, compressing the reset spring 76. The elastic force of the reset spring 76 ensures that the U-shaped block 81 is close to the bottom of the inverted plastic storage box 24, thereby ensuring that the V-shaped cutting knife 82 is close to the bottom of the inverted plastic storage box 24, and further ensuring that the V-shaped cutting knife 82 can smoothly cut off the water outlet 25 at the bottom of the plastic storage box 24. When the plastic storage box 24 moves to the left, the sprue 25 at its bottom contacts the V-shaped cutting knife 82, and the sprue 25 is cut off by the V-shaped cutting knife 82. Compared with a flat cutting knife, the V-shaped cutting knife 82 can better fit the shape of the sprue 25, thereby achieving more precise cutting. Compared with a wide-blade cutting knife, the V-shaped cutting knife 82 can quickly cut off the sprue 25 with less force.

[0032] After the nozzle 25 is removed, the plastic storage box 24 continues to move to the left and separates from the U-shaped block 81. Under the reset action of the reset spring 76, the lifting block 75 is pushed to move down and reset with the U-shaped block 81, and the V-shaped cutting knife 82 and the inclined rod 83 move down and reset accordingly. After the nozzle 25 is removed, the plastic storage box 24 continues to move to the left to just below the pressing block 103, and is located just below the profiling plate 11 and aligned with the profiling plate 11. During this process, the bottom of the inverted plastic storage box 24 and the upper and lower flashes 26 on the concave handle are respectively contacted with the upper and lower cutters 17 and cut off by the cutters 17. The mounting plate 4 drives the plastic storage box 24 to move to the left to just below the profiling plate 11 through the rotary placement table 5, and drives the transmitter of the infrared sensor 41 to move to the left to just above the receiver. When the receiver of the infrared sensor 41 receives the infrared light beam sent by the transmitter, the infrared sensor 41 sends a signal to the controller (the controller is not shown in the figure, the controller is prior art and will not be described here). After receiving the signal, the controller first controls the electric slide rail 3 to close, and then controls the electric push rod 1 102 to drive the pressing block 103 to move down to press and fix the plastic storage box 24 on the placement plate 52, and then controls the motor 1 51 and the motor 2 101 to work synchronously, thereby driving the profiling plate 11 and the plastic storage box 24 to rotate synchronously. When the profiling plate 11 rotates, it pushes the contact plate 12 to move forward and compress the support spring 13. The support spring 13 enables the contact plate 12 to always keep in contact with the profiling plate 11, thereby ensuring that the cutter 17 can always keep in contact with the flash 26 to cut off the flash 26. The rotation of the plastic storage box 24 can make the entire circle of flash 26 contact with the cutter 17 and be completely cut off. In this way, the device can automatically remove the sprue 25 and the flash 26, realize the trimming of the entire plastic storage box 24, and improve production efficiency.

[0033] After the flash 26 is removed, the electric push rod 102 is first controlled to drive the pressing block 103 to move up and disengage from the plastic storage box 24, and then the electric slide rail 3 is controlled to drive the mounting plate 4 to drive the rotary placement table 5 to continue to move to the left, thereby driving the plastic storage box 24 to continue to move to the left away from the pressing block 103 and the profiling plate 11, and then the trimmed plastic storage box 24 is removed from the rotary placement table 5, and finally the electric slide rail 3 is controlled to drive the mounting plate 4 to drive the rotary placement table 5 to move rightward and reset, so as to carry out the next round of trimming operation of the plastic storage box 24. The screw rod 1 71 can be rotated to drive the nut 1 72 to drive the U-shaped plate 73 to rise and fall, thereby driving the lifting block 75 to rise and fall through the reset spring 76, and then driving the tool 8 to rise and fall, and adjusting the height of the tool 8 to adapt to the plastic storage boxes 24 of different heights. The height of the upper and lower guide sleeves 15 can be adjusted through the height adjustment component 2, thereby adjusting the height of the cutter 17 to adapt to the plastic storage boxes 24 of different heights. The locking of the connecting rod 16 can be released by loosening the fastening bolt 18, and then the connecting rod 16 can be moved forward and backward, so as to adjust the front and rear position of the cutter 17 to adapt to plastic storage boxes 24 of different sizes, and the connecting rod 16 can be re-locked by tightening the fastening bolt 18. In a specific implementation, different sizes of profiling plates 11 are designed, and different sizes of profiling plates 11 can be replaced to adapt to plastic storage boxes 24 of different sizes.

[0034] See also Figure 8 , Fig.10 and Fig.11 The second height adjustment component includes a screw rod 141 fixedly connected to the contact plate 12, and the screw rod 141 is threadedly connected with two upper and lower nuts 142. The screw rod 141 is slidably sleeved with upper and lower lifting rings 143. The two lifting rings 143 are rotatably connected to the two nuts 142. The left and right sides of the screw rod 141 are both provided with notches 145. The lifting ring 143 is connected with an inner diamond block 144 matching the notch 145. The lifting and lowering of the lifting ring 143 is guided by the cooperation of the notch 145 and the inner diamond block 144 to ensure that the lifting and lowering of the lifting ring 143 can only be lifted and lowered but cannot be rotated. The two guide sleeves 15 are respectively connected to the right sides of the outer walls of the two lifting rings 143. The nut 142 can be rotated to make the nut 142 rise and fall. The lifting and lowering of the nut 142 drives the lifting and lowering of the lifting ring 143 to adjust the height of the guide sleeve 15, thereby adjusting the height of the cutter 17 to adapt to storage boxes 24 of different heights.

[0035] See also Figure 8 An electric push rod 21 is installed in the middle of the top of the placement plate 52, and a support block 22 for supporting the storage box 24 is connected to the push rod of the electric push rod 21.

[0036] When the placement plate 52 drives the storage box 24 to move to the left to the position directly below the pressing block 103, the electric push rod 21 and the support block 22 move to the position directly below the pressing block 103. The controller controls the electric push rod 102 to drive the pressing block 103 downward, and the controller controls the electric push rod 21 to drive the support block 22 upward to contact the storage box 24. Through the synergistic effect of the pressing block 103 and the support block 22, the centering of the storage box 24 can be achieved, ensuring that its position on the placement plate 52 is more stable, which can not only prevent the storage box 24 from being offset due to the swinging when rotating, improve the accuracy of removing the flash 26, but also effectively prevent the storage box 24 from being squeezed and deformed by the pressing block 103. After the flash 26 is removed, the electric push rod 21 is controlled to drive the support block 22 downward to separate from the storage box 24.

[0037] See also Figure 3 The bottom of the pressing block 103 and the top of the supporting block 22 are both connected with a useful rubber block 23, which can prevent the pressing block 103 and the supporting block 22 from directly and rigidly squeezing the storage box 24, so as to provide buffer protection for the storage box 24 and prevent the storage box 24 from being damaged.

[0038] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
