Description

Technical Field

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

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

[0003] During the production process of circular plastic blister boxes, a flash trimmer is usually used to remove the excess material from the edges of workpieces. Traditional flash trimmers usually use mechanical clamps to fix the workpieces. The mechanical clamps rely on manual adjustment, resulting in uneven clamping forces on plastic blister boxes of different sizes. Displacement is likely to occur during the processing (deviation of more than ±0.5 mm), which may easily lead to uneven trimming or even scrapping of the workpieces. Moreover, different types of workpieces usually require flash cutter heads of different sizes. Currently, the flash cutter heads are usually fixed by multiple screws, making the disassembly and replacement process cumbersome and reducing efficiency. Therefore, we have designed a flash trimmer for circular plastic 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 a flash trimmer for circular plastic blister box production is proposed. It can adsorb and fix circular plastic blister boxes according to their sizes, facilitating the flash trimming work. It can also adjust the position of the flash cutter head and quickly disassemble and replace the flash cutter head, with simple operation and high efficiency.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A flash trimmer for the production of circular blister boxes, comprising a frame and a flash trimming cutter head. The upper end of the frame is fixedly connected with a U-shaped frame. An installation plate is vertically slidably connected inside the U-shaped frame. The installation plate is driven to move vertically by a height adjustment component. A plurality of I-shaped plates that can move left and right are arranged on the U-shaped frame. A first driving motor is installed at the bottom of the I-shaped plate. A connecting plate is installed at the end of the output shaft of the first driving motor. The flash trimming cutter head is detachably connected to the connecting plate. Electric slide rails are installed on the inner side walls at both ends of the frame. Electric sliders adapted to them are installed in both electric slide rails. Second driving motors are installed on the side walls of both electric sliders. A placing plate is jointly installed at the ends of the output shafts of the two second driving motors. Two clamping plates are horizontally slidably connected to the placing plate. The two clamping plates are driven by a driving component to approach or move away from each other. Support plates that can move up and down are installed on both clamping plates. At least one vacuum suction cup is installed on each of the two support plates. Air pumps communicated with the corresponding vacuum suction cups are installed at the bottoms of the two support plates. A storage box is placed below the frame.

[0007] Preferably, guide sliding grooves are formed on the inner side walls at both ends of the U-shaped frame. Guide sliders adapted to them are slidably connected in both guide sliding grooves. The two guide sliders are respectively fixedly connected to the side walls at both ends of the installation plate.

[0008] Preferably, the height adjustment component includes two convex plates respectively fixedly connected to the rear side walls of the U-shaped frame and the installation plate. A cylinder is installed between the two convex plates.

[0009] Preferably, a through opening is formed through the installation plate. The I-shaped plate is horizontally slidably connected in the through opening and is adapted to it. A fixed sliding groove is formed at the upper end of the installation plate. A first threaded rod is threaded through the I-shaped plate. An anti-slip pad that abuts against the inner bottom of the fixed sliding groove is fixedly connected to the bottom of the first threaded rod.

[0010] Preferably, a rectangular notch is formed at the bottom of the connecting plate. The upper end of the flash trimming cutter head is connected with a rectangular block through an installation rod. The rectangular block is inserted into the rectangular notch and is adapted to it. A plurality of baffles that abut against the bottom of the rectangular block are rotatably connected to the connecting plate.

[0011] Preferably, a limiting sliding groove is formed through the placing plate. Two limiting sliders adapted to it are slidably connected in the limiting sliding groove. The two clamping plates are respectively fixedly connected to the upper ends of the two limiting sliders.

[0012] 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.

[0013] Preferably, a vertical sliding groove is formed in the side wall of the clamping plate. A connecting slider adapted to it is slidably connected in the vertical sliding groove. The support plate is fixedly connected to the side wall of the connecting slider. The inner bottom of the vertical sliding groove is rotatably connected with a second threaded rod extending above the clamping plate, and the second threaded rod threadedly penetrates through the connecting slider.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. For the flash trimming machine for producing circular plastic suction boxes of the present invention, adjust the distance between the two clamping plates to be adapted to the circular plastic suction box. Place the edge of the circular plastic suction box on the vacuum suction cup. By pumping air out of the vacuum suction cup with an air pump, the edge of the circular plastic suction box can be stably adsorbed on the vacuum suction cup. The placing plate moves back and forth, the cylinder drives the mounting plate to move up and down, and the first driving motor drives the flash trimming cutter head to rotate, so as to perform flash trimming work on the circular plastic suction box. After the work is completed, the second driving motor drives the placing plate to flip, enabling the plastic suction box after flash trimming work to fall into the storage box for centralized collection.

[0016] 2. For the flash trimming machine for producing circular plastic suction boxes of the present invention, rotate the first threaded rod to make the anti-slip pad move upward and no longer abut against the inner bottom of the fixed sliding groove, which can enable the I-shaped plate to slide in the through hole and adjust the position of the flash trimming cutter head. By making the anti-slip pad abut against the inner bottom of the fixed sliding groove, the position of the I-shaped plate can be stably fixed, completing the adjustment of the position of the flash trimming cutter head. Rotate the baffle so that it no longer abuts against the rectangular block, and the rectangular block can be taken out from the rectangular notch, and then the flash trimming cutter head can be taken out. Insert the rectangular block at the upper end of the replaced flash trimming cutter head into the rectangular notch, and rotate the baffle so that it abuts against the bottom of the rectangular block, which can stably fix the rectangular block in the rectangular notch, completing the disassembly and replacement of the flash trimming cutter head.

Detailed implementation method

[0025] 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.

[0026] Referring to Figures 1 - 7 , a flash trimming machine for producing circular plastic blister boxes includes 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;

[0027] The installation plate 4 is driven to move vertically by a height adjustment assembly. The height adjustment assembly 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 can drive the installation plate 4 to move up and down to adjust the height;

[0028] There are multiple I-shaped plates 8 that can move left and right on the U-shaped frame 2. A through hole 7 is formed through 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 sliding groove 9 is formed at the upper end of the mounting plate 4. A first threaded rod 10 is threadedly connected through 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 sliding groove 9. Anti-slip patterns are provided at the inner bottom of the fixed sliding groove 9. The upper end of the first threaded rod 10 is fixedly connected with a rotating handle. Rotating the rotating handle to rotate the first threaded rod 10 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 sliding groove 9, which can stably fix the position of the I-shaped plate 8. Furthermore, by sliding the I-shaped plate 8 in the through hole 7, the flash cutter head 14 can be horizontally moved, and thus the position of the flash cutter head 14 can be adjusted according to the positions of plastic suction boxes of different batches and different specifications;

[0029] 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 cutter head 14 is detachably connected to the connecting plate 13. A rectangular notch is formed at the bottom of the connecting plate 13. The upper end of the flash 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 magnetic block is embedded in the inner top of the rectangular notch. A second magnetic block is embedded in the upper end of the rectangular block 16. The opposite side walls of the second magnetic block and the first magnetic block have opposite magnetic poles, which 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 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 cutter head 14 can be disassembled and replaced;

[0030] Electric sliding 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 sliding rails 18. Second driving motors 19 are installed on the side walls of both electric sliders. The ends of the output shafts of the two second driving motors 19 are jointly installed with a placement plate 20. Starting the second driving motor 19 can drive the placement plate 20 to flip, which is beneficial for the plastic suction boxes after flash treatment to fall into the storage box 32 for centralized collection. Two clamping plates 31 are horizontally slidably connected to the placement plate 20. A limiting sliding groove 21 is formed through the placement plate 20. Two limiting sliders 22 adapted to it are slidably connected in the limiting sliding groove 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 sliding groove 21, which can play a guiding role for the clamping plates 31, so that the clamping plates 31 can only slide left and right;

[0031] The two clamping plates 31 are driven by a driving assembly to approach or move away from each other. The driving assembly includes two mounting brackets 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 brackets 23. The end of the output shaft of the servo motor 24 is mounted with a double-headed screw rod 25. The double-headed screw rod 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 rod 25. When the servo motor 24 drives the double-headed screw rod 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 rod 25 is rotatably connected to the side wall of the other mounting bracket 23, which can ensure the stability of the double-headed screw rod 25;

[0032] 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 groove 26 is slidably connected in the vertical sliding groove 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 at 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 both of the two support plates 27. Air pumps 29 communicated with the corresponding vacuum suction cups 30 are mounted at 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 to fix the vacuum suction cup 30, which is beneficial to the flashing operation.

[0033] A storage box 32 is placed below the frame 1, and the plastic suction boxes after flashing can fall into the storage box 32 for centralized collection.

[0034] The functional principle of the present invention can be described through the following operation method:

[0035] In the present invention, when the flash trimming machine for producing the circular plastic suction 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 plastic suction box. The edge of the circular plastic suction 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 plastic suction 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 placement 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 plastic suction 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. Repeat the above actions to perform flash trimming work on the circular plastic suction box in sequence;

[0036] After the plastic suction 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 placement plate 20 to flip, so that the placement plate 20 can be tilted, and the plastic suction box after the flash trimming work on the placement plate 20 falls into the storage box 32 for centralized collection;

[0037] 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 plastic suction box, rotate the first threaded rod 10. 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 head 14. After the adjustment is completed, rotate the first threaded rod 10 so that 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 to complete the adjustment of the position of the flash trimming cutter head 14;

[0038] Rotate the baffle 17 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. Insert the rectangular block 16 at the upper end of the replaced flash trimming cutter head 14 into the rectangular notch, and rotate the baffle 17 so that it abuts against the bottom of the rectangular block 16, and 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.

[0039] The above is only a preferred specific embodiment 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 should be covered by the protection scope of the present invention.
