Description

Technical Field

[0001] The present invention relates to the technical field of circular blister box production, and particularly to a flash trimmer for circular blister box production. Background Art

[0002] A circular blister box refers to a circular plastic product made by the blister process. It has a non - angular design, a round and beautiful appearance, is suitable for displaying delicate items such as jewelry, cosmetics, and food, and has a smooth edge, reducing frictional damage to the contents during transportation. It is commonly used in scenarios such as packaging and storage, and has characteristics such as being lightweight, transparent, and low - cost.

[0003] During the production of circular blister boxes, a flash trimmer is usually used to remove excess material from the edges of workpieces. Traditional flash trimmers usually use mechanical jigs to fix workpieces. The mechanical jigs rely on manual adjustment, and the clamping force on blister boxes of different sizes is uneven. Displacement is likely to occur during the processing (deviation of more than ±0.5 mm), which is likely to lead to uneven trimming or even scrapping. Moreover, different types of workpieces usually require flash cutter heads of different sizes. Currently, flash cutter heads are usually fixed by tightening multiple screws, making the disassembly and replacement process cumbersome and reducing efficiency. For this reason, we have designed a flash trimmer for circular blister box production to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems existing in the prior art, and to propose a flash trimmer for circular blister box production, which can adsorb and fix circular blister boxes according to their sizes, facilitating flash trimming work, can adjust the position of the flash cutter head, and can quickly disassemble and replace the flash cutter head, with simple operation and high efficiency.

[0010] Preferably, a limit sliding groove is penetrated through the placement plate. Two limit sliders adapted to it are slidably connected in the limit sliding groove. The two clamping plates are respectively fixedly connected to the upper ends of the two limit sliders.

[0011] Preferably, the driving assembly includes two mounting brackets fixedly connected to the bottom of the placing plate. A servo motor is mounted on the side wall of one of the mounting brackets. The end of the output shaft of the servo motor is mounted with a double-headed screw rod, which threadedly penetrates through two limit sliders, and the double-headed screw rod is rotatably connected to the side wall of the other mounting bracket.

Specific embodiments

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0018] Refer to Figures 1-7 , a flash trimming machine for producing circular plastic suction boxes, including a frame 1 and a flash trimming cutter head 14. A U-shaped frame 2 is fixedly connected to the upper end of the frame 1. An installation plate 4 is vertically slidably connected inside the U-shaped frame 2. Guide chutes 3 are opened on the inner side walls at both ends of the U-shaped frame 2. Guide sliders adapted to them are slidably connected in the two guide chutes 3. The two guide sliders are respectively fixedly connected to the side walls at both ends of the installation plate 4. The guide sliders slide in the guide chutes 3, which can play a guiding role for the installation plate 4, so that the installation plate 4 can only move vertically; The installation plate 4 is driven to move vertically by a height adjustment component. The height adjustment component includes two convex plates 5 respectively fixedly connected to the rear side walls of the U-shaped frame 2 and the installation plate 4. A cylinder 6 is installed between the two convex plates 5. The fixed end of the cylinder 6 is installed on the convex plate 5 of the U-shaped frame 2, and the end of the telescopic end of the cylinder 6 is connected to the convex plate 5 at the rear side of the installation plate 4. Starting the cylinder 6, the cylinder 6 can drive the installation plate 4 to move up and down to adjust the height; There are multiple I-shaped plates 8 that can move left and right on the U-shaped frame 2. A through hole 7 is penetrated and opened on the mounting plate 4. The I-shaped plate 8 is horizontally slidably connected in the through hole 7 and is adapted to it, so that the I-shaped plate 8 can only move horizontally in the through hole 7. A fixed chute 9 is opened at the upper end of the mounting plate 4. A first threaded rod 10 is penetrated and threadedly connected on the I-shaped plate 8. The bottom of the first threaded rod 10 is fixedly connected with an anti-slip pad 11 that abuts against the inner bottom of the fixed chute 9. The inner bottom of the fixed chute 9 is provided with anti-slip lines. The upper end of the first threaded rod 10 is fixedly connected with a rotating handle. Rotating the rotating handle to make the first threaded rod 10 rotate can drive the anti-slip pad 11 to move up and down under the action of its threaded engagement with the I-shaped plate 8. The anti-slip pad 11 abuts against the inner bottom of the fixed chute 9, and the position of the I-shaped plate 8 can be stably fixed. Furthermore, by sliding the I-shaped plate 8 in the through hole 7, the flash trimming cutter head 14 can be horizontally moved, and thus the position of the flash trimming cutter head 14 can be adjusted according to the positions of plastic suction boxes of different batches and different specifications. A first driving motor 12 is installed at the bottom of the I-shaped plate 8. The end of the output shaft of the first driving motor 12 is installed with a connecting plate 13. The flash trimming cutter head 14 is detachably connected to the connecting plate 13. A rectangular notch is opened at the bottom of the connecting plate 13. The upper end of the flash trimming cutter head 14 is connected with a rectangular block 16 through a mounting rod 15. The rectangular block 16 is inserted into the rectangular notch and is adapted to it. A first magnet is embedded in the inner top of the rectangular notch. A second magnet is embedded in the upper end of the rectangular block 16. The opposite side walls of the second magnet and the first magnet have opposite magnetic poles and can generate an attractive force to initially fix the rectangular block 16 in the rectangular notch. A plurality of baffles 17 that abut against the bottom of the rectangular block 16 are rotatably connected to the connecting plate 13. Rotating the baffle 17 to make it abut against the bottom of the rectangular block 16 can initially stably fix the rectangular block 16 in the rectangular notch. Rotating the baffle 17 so that it no longer abuts against the rectangular block 16 can take out the rectangular block 16 from the rectangular notch, and thus the flash trimming cutter head 14 can be disassembled and replaced. Electric slide rails 18 are installed on the inner side walls at both ends of the frame 1. Electric sliders adapted to them are installed in both electric slide rails 18. Second driving motors 19 are installed on the side walls of both electric sliders. A placing plate 20 is jointly installed at the ends of the output shafts of the two second driving motors 19. Starting the second driving motor 19 can drive the placing plate 20 to flip, which is beneficial for the plastic suction boxes after flash trimming to fall into the storage box 32 for centralized collection. Two clamping plates 31 are horizontally slidably connected to the placing plate 20. A limiting chute 21 is penetrated and opened on the placing plate 20. Two limiting sliders 22 adapted to it are slidably connected in the limiting chute 21. The two clamping plates 31 are respectively fixedly connected to the upper ends of the two limiting sliders 22. The limiting sliders 22 slide in the limiting chute 21, which can play a guiding role for the clamping plates 31 and make the clamping plates 31 only able to slide left and right. The two clamping plates 31 are driven by a driving component to approach or move away from each other. The driving component includes two mounting frames 23 fixedly connected to the bottom of the placement plate 20. A servo motor 24 is mounted on the side wall of one of the mounting frames 23. The end of the output shaft of the servo motor 24 is mounted with a double-headed screw 25. The double-headed screw 25 threadedly penetrates through the two limit sliders 22. The two limit sliders 22 are respectively connected to two opposite threaded sections of the double-headed screw 25. When the servo motor 24 drives the double-headed screw 25 to rotate, under the action of its thread engagement, the two limit sliders 22 can drive the two clamping plates 31 to approach or move away from each other. The double-headed screw 25 is rotatably connected to the side wall of the other mounting frame 23, which can ensure the stability of the double-headed screw 25; Support plates 27 that can move up and down are mounted on both of the two clamping plates 31. Vertical sliding grooves 26 are formed in the side walls of the clamping plates 31. A connecting slider adapted to the vertical sliding grooves 26 is slidably connected in the vertical sliding grooves 26. The support plate 27 is fixedly connected to the side wall of the connecting slider. The inner bottom of the vertical sliding groove 26 is rotatably connected with a second threaded rod 28 extending above the clamping plate 31. The second threaded rod 28 threadedly penetrates through the connecting slider. A rotating handle for facilitating the rotation of the second threaded rod 28 is mounted on the upper end of the second threaded rod 28. When the second threaded rod 28 rotates, under the action of its thread engagement, the connecting slider can drive the support plate 27 to move up and down, and the height of the support plate 27 can be adjusted according to the height of the plastic suction box. At least one vacuum suction cup 30 is mounted on each of the two support plates 27. Air pumps 29 communicated with the corresponding vacuum suction cups 30 are mounted on the bottoms of the two support plates 27. By placing the edge of the circular plastic suction box on the vacuum suction cup 30 and evacuating the vacuum suction cup 30 through the air pump 29, the edge of the circular plastic suction box can be stably adsorbed on the vacuum suction cup 30, fixing the vacuum suction cup 30, which is beneficial to the flashing operation.

[0019] A storage box 32 is placed below the frame 1. The plastic suction boxes after flashing can fall into the storage box 32 for centralized collection.

[0020] The functional principle of the present invention can be described through the following operation method: In the present invention, when the flash trimmer for producing the circular blister box is working, the servo motor 24 drives the double-headed screw 25 to rotate. Under the action of its thread engagement, the two limit sliders 22 drive the two clamping plates 31 to approach or move away from each other, so that the distance therebetween is adapted to the length of the circular blister box. The edge of the circular blister box is placed on the vacuum suction cup 30, and the air pump 29 evacuates the vacuum suction cup 30, so that the edge of the circular blister box can be stably adsorbed on the vacuum suction cup 30. The electric slider slides in the electric slide rail 18, which can drive the placing plate 20 to move back and forth. The air cylinder 6 can drive the mounting plate 4 to move up and down to adjust its height. The flash trimming cutter head 14 extends into the circular blister box, and the first driving motor 12 drives the connecting plate 13 to rotate, so that the flash trimming cutter head 14 can rotate to perform flash trimming work. By repeating the above actions, the circular blister box is flash trimmed in sequence; After the blister work is completed, the air pump 29 is turned off, and the waste can be removed from the vacuum suction cup 30. The second driving motor 19 drives the placing plate 20 to turn over, so that the placing plate 20 can be inclined, and the blister box after the flash trimming work on the placing plate 20 falls into the storage box 32 for centralized collection; When it is necessary to adjust the distance between the flash trimming cutter heads 14 or replace the flash trimming cutter heads 14 according to the size of the circular blister box, the first threaded rod 10 is rotated. Under the action of its thread engagement with the I-shaped plate 8, the first threaded rod 10 drives the anti-slip pad 11 to move upward and no longer abut against the inner bottom of the fixed chute 9, so that the I-shaped plate 8 can slide in the through hole 7 to adjust the position of the flash trimming cutter heads 14. After the adjustment is completed, the first threaded rod 10 is rotated to make the anti-slip pad 11 abut against the inner bottom of the fixed chute 9, so that the position of the I-shaped plate 8 can be stably fixed, and the adjustment of the position of the flash trimming cutter heads 14 is completed; The baffle 17 is rotated so that it no longer abuts against the rectangular block 16, and the rectangular block 16 can be taken out of the rectangular notch, and then the flash trimming cutter head 14 can be taken out. The rectangular block 16 at the upper end of the replaced flash trimming cutter head 14 is inserted into the rectangular notch, and the baffle 17 is rotated to make it abut against the bottom of the rectangular block 16, so that the rectangular block 16 can be stably fixed in the rectangular notch, and then the disassembly and replacement of the flash trimming cutter head 14 can be completed.

[0021] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
