Description

Technical Field

[0001] This invention relates to the field of packaging box manufacturing technology, and in particular to a license plate packaging box and its preparation apparatus. Background Technology

[0002] License plate boxes are generally used to store and protect car license plates, especially when car owners purchase new plates. They not only protect the license plate from damage but also effectively protect it from external impacts during transportation or storage, preventing deformation or scratches and keeping it clean and intact. Existing license plate boxes on the market have certain shortcomings, such as unstable structure, susceptibility to deformation and breakage, and inability to meet the requirements of automated assembly. Therefore, a license plate box and its manufacturing device are designed to solve the aforementioned problems. Summary of the Invention

[0003] This invention addresses the problems of unstable, easily deformed, and easily damaged existing license plate boxes by providing a license plate packaging box and its manufacturing apparatus. This improves the overall stability of the box and prevents deformation and damage during transportation, effectively solving the problems mentioned in the background art.

[0004] The technical solution adopted by the present invention to solve the above problems is as follows:

[0005] A license plate packaging box and its manufacturing apparatus include a base box and a top cover. When the base box is unfolded, it has a short folded edge and a long folded edge on two opposite sides. The short folded edge has multiple first slots and first ear pieces. When the short folded edge is folded, the first slots and first ear pieces cooperate to keep the folded short folded edge in a stable state. The long folded edge has multiple second slots and second ear pieces. When the long folded edge is folded, the second slots and second ear pieces cooperate to keep the folded long folded edge in a stable state. The two sides of the long folded edge have first hanging pieces and second hanging pieces that cooperate with the first slots. When the top cover is unfolded, it has a wide folded edge and a narrow folded edge on two opposite sides. The top cover also has a window.

[0006] A device for preparing a license plate packaging box includes an operating table. The upper end of the operating table is provided with a mold table adapted to the bottom box. The upper end of the operating table is also provided with a drive arm that can move up and down. The drive arm is provided with a punching mechanism. The mold table is also provided with a clamping mechanism, which includes multiple clamping rods. When the drive arm moves downward, it can form a structure in which multiple clamping rods move inward synchronously and the punching mechanism moves downward to punch the bottom box.

[0007] A vertical plate is fixedly attached to the upper surface of the operating platform, and a drive arm is slidably connected to the inner wall of the vertical plate. The inner wall of the vertical plate is also provided with a lifting rod that cooperates with the drive arm. The punching mechanism includes an upper pressure plate and a lower pressure plate, and the upper pressure plate is fixedly attached to the drive arm.

[0008] Short guide rods are fixedly connected to the four corners of the upper surface of the lower pressure plate, and the upper pressure plate is slidably connected to the outer surface of the four short guide rods. A first spring that cooperates with the upper pressure plate is sleeved on the outer surface of each short guide rod.

[0009] The lower end surface of the lower pressure plate is fixed with a plurality of arc-shaped cutting blades corresponding to the first ear piece and the second ear piece, and the lower end surface of the upper pressure plate is fixed with a plurality of through blades corresponding to the first slot and the second slot. Mold blades are fixed on both sides of the lower end surface of the upper pressure plate, and the through blades and mold blades are slidably connected to the inner wall of the lower pressure plate.

[0010] The clamping mechanism also includes multiple clamping seats that are slidably connected to the mold table. The clamping rods are slidably connected to the inner walls of the clamping seats. Square bases are slidably connected to the inner walls of the bottom ends of the clamping seats. First movable pins are fixedly connected to the inner walls of the square bases. Multiple guide plates are fixedly connected to the lower surface of the mold table. Short horizontal grooves and short oblique grooves that cooperate with the first movable pins are respectively opened on the guide plates. Second springs that cooperate with the clamping rods are fixedly connected to the upper surface of the square bases.

[0011] The lower end of the mold platform is provided with a rotatable first disk. The lower surface of the first disk is hinged with two centrally symmetrical first connecting rods. The clamping base includes two first clamping bases and two second clamping bases. The outer ends of the two first connecting rods are respectively hinged to the corresponding first clamping bases. The lower surface of the first clamping base is fixed with a first connecting plate. The lower surface of the second clamping base is fixed with a second connecting plate. The front and rear ends of the second connecting plate are respectively fixed with square guide plates. The left and right sides of the lower surface of the first connecting plate are respectively fixed with first sliding pins. The square guide plates are respectively provided with oblique keyways that cooperate with the first sliding pins.

[0012] A spur gear is coaxially fixed to the upper end of the first disk, and a spur rack meshes on the outer surface of the spur gear. A first drive plate is fixed to the front end surface of the second spur rack, and a first drive pin is fixed to one end face of the drive arm. The first drive plate is provided with a long inclined groove and a long vertical groove that cooperate with the first drive pin.

[0013] The upper surface of the operating platform is slidably connected to a second drive plate that can move back and forth, and the upper surface of the operating platform is also slidably connected to a support. The support is fixed to the front end of the second drive plate, and a collection box is placed on the upper end of the support.

[0014] A cylindrical seat is fixedly connected to the other end face of the drive arm. A second drive pin is slidably connected to the inner wall of the cylindrical seat. A third spring that cooperates with the second drive pin is fixedly connected to the inner wall of the bottom end of the cylindrical seat. A first vertical groove, a first inclined groove, a wave groove and a second inclined groove that cooperate with the second drive pin are opened on the second drive plate.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] In use, the set pressure lines allow for folding of short, long, wide, and narrow edges. When the short edge is folded vertically upwards along the pressure lines, the first ear piece can be fastened into the corresponding first slot, preventing the folded short edge from unraveling and thus keeping it stable. By bending the first and second hanging pieces, they can be hooked into the corresponding first slots, connecting and fixing the folded short and long edges. The cooperation of the first and second hanging pieces with the first slots further enhances the folding effect. This design improves the overall stability of the bottom box structure, and the short and long folds have a double layer after folding, preventing deformation and damage during transportation. The prepared device allows the bottom box to be cut into the desired shape when the punching mechanism moves downwards. The clamping mechanism, consisting of multiple clamping rods, first moves inwards to center the bottom box and then clamps it in place to prevent movement when the drive arm moves downwards. Subsequently, the punching mechanism moves downwards to the designated position to punch the bottom box, thus producing the desired shape. Attached Figure Description

Detailed Implementation

[0035] The following are specific embodiments of the present invention, and the technical solutions of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0036] like Figures 1-17 As shown, the present invention provides a license plate packaging box, including a bottom box 12 and a top cover 61. When the bottom box 12 is unfolded, two opposite sides are provided with a short folded edge 56 and a long folded edge 57, respectively. The short folded edge 56 is provided with a plurality of first slots 50 and first ear pieces 51. When the short folded edge 56 is folded, the cooperation of the first slots 50 and the first ear pieces 51 can make the folded short folded edge 56 stable. The long folded edge 57 is provided with a plurality of second slots 54 and second ear pieces 55, and the cooperation of the second slots 54 and the second ear pieces 55 can make the folded long folded edge 57 stable. The two sides of the long folded edge 57 are provided with a first hanging piece 52 and a second hanging piece 53 that cooperate with the first slots 50, respectively. When the top cover 61 is unfolded, two opposite sides are provided with a wide folded edge and a narrow folded edge 62, respectively. The top cover 61 is also provided with a window 60.

[0037] like Figures 1-2 As shown, the bottom box 12 and the top cover 61 are respectively provided with multiple pressure lines. The pressure lines can be used to fold the short fold 56, long fold 57, wide fold 58, and narrow fold 62. When the short fold 56 is folded vertically upward along the pressure line, the first ear piece 51 can be fastened in the corresponding first slot 50, which can prevent the folded short fold from spreading out, thus keeping the folded short fold in a stable state. Similarly, when the long fold 57 is folded, the second ear piece 55 can be fastened in the second slot 54, which can prevent the folded long fold from spreading out, thus keeping the folded long fold in a stable state. After the short fold 56 and the long fold 57 are folded vertically, the first hanging piece 52 and the second hanging piece 53 can be bent to hang the folded long fold. The first slot 50 is fastened to the corresponding slot 50, which can connect and fix the folded short edge 56 and long edge 57. With the cooperation of the first hanging piece 52, the second hanging piece 53 and the first slot 50, the overall stability of the bottom box 12 structure can be improved. The short edge 56 and long edge 57 have double layers after folding to prevent deformation and damage during transportation. The bottom box 12 and the top cover 61 are made of anti-paper material to improve the overall rigidity. The wide edge includes the first edge 58 and the second edge 59. The top cover 61 has a pressure line to allow the first edge 58, the second edge 59 and the narrow edge 62 to be folded and assembled. The window 60 makes it easy to observe the license plate information inside. The top cover 61 is existing technology and will not be described in detail.

[0038] A device for preparing a license plate packaging box includes an operating table 1. The upper end of the operating table 1 is provided with a mold table 11 adapted to a bottom box 12. The upper end of the operating table 1 is also provided with a drive arm 3 that can move up and down. The drive arm 3 is provided with a punching mechanism. The mold table 11 is also provided with a clamping mechanism. The clamping mechanism includes multiple clamping rods 27. When the drive arm 3 moves downward, it can form a structure in which multiple clamping rods 27 move inward synchronously and the punching mechanism moves downward to punch the bottom box 12.

[0039] like Figures 3-12 The bottom of the operating table 1 is equipped with multiple support legs 37, which are used to support the entire device; the shape of the mold table 11 is as follows: Figure 7 As shown, it is adapted to the bottom box 12. When the punching mechanism moves downward to punch, it can cut the bottom box 12 into the required shape. Through the clamping mechanism, i.e., multiple clamping rods 27, when the drive arm 3 moves downward, the clamping rods 27 can first move inward to center the bottom box 12 and then clamp and fix it to prevent movement. Then the punching mechanism can move downward to the designated position to punch the bottom box 12, thereby processing the required shape.

[0040] The upper surface of the operating table 1 is fixedly connected to a vertical plate 2, and the drive arm 3 is slidably connected to the inner wall of the vertical plate 2. The inner wall of the vertical plate 2 is also provided with a lifting rod that cooperates with the drive arm 3. The punching mechanism includes an upper pressure plate 4 and a lower pressure plate 5, and the upper pressure plate 4 is fixedly connected to the drive arm 3.

[0041] like Figures 5-7 , Figure 13 As shown, the upright plate 2 is used to support the limiting drive arm 3. The drive arm 3 can slide up and down on the upright plate 2. The drive arm 3 can move up and down when the lifting rod is working. The lifting rod can be an electric telescopic rod. The lifting rod is existing technology and will not be described in detail. The lower pressure plate 5 is used to press and fix the bottom box 12 during punching. The upper pressure plate 4 can punch the bottom box 12 when it moves down. The upper pressure plate 4 is fixed on the drive arm 3. When the drive arm 3 moves up and down, it can drive the punching mechanism to move up and down.

[0042] Short guide rods 9 are fixedly connected to the four corners of the upper surface of the lower pressure plate 5, and the upper pressure plate 4 is slidably connected to the outer surface of the four short guide rods 9. The outer surface of the short guide rods 9 is fitted with a first spring 10 that cooperates with the upper pressure plate 4.

[0043] like Figures 4-6As shown, the four short guide rods 9 enable the upper pressure plate 4 and the lower pressure plate 5 to slide together, which is equivalent to the lower pressure plate 5 slidingly connected to the lower end of the upper pressure plate 4. Anti-detachment caps are fixed to the upper surfaces of the short guide rods 9 respectively, which can prevent the upper pressure plate 4 from separating from the short guide rods 9. The first spring 10 always exerts a downward driving force on the lower pressure plate 5, so that the lower pressure plate 5 can be in the lowest position under normal conditions. When the drive arm 3 moves downward, it can drive the upper pressure plate 4, the lower pressure plate 5 and so on to move downward synchronously. When the lower pressure plate 5 moves downward, it can first contact the bottom box 12. After contacting the bottom box 12, it can squeeze and fix the bottom box 12, so that the punching can be more precise. After the lower pressure plate 5 is squeezed and fixed, the upper pressure plate 4 continues to move downward to punch the bottom box 12.

[0044] The lower end surface of the lower pressure plate 5 is fixed with a plurality of arc-shaped cutters 6 corresponding to the first ear piece 51 and the second ear piece 55, and the lower end surface of the upper pressure plate 4 is fixed with a plurality of through cutters 7 corresponding to the first slot 50 and the second slot 54. The two sides of the lower end surface of the upper pressure plate 4 are fixed with mold cutters 8, and the through cutters 7 and the mold cutters 8 are slidably connected to the inner wall of the lower pressure plate 5.

[0045] like Figures 5-6 As shown, the arc-shaped cutter 6 can cut the bottom box 12 when the lower pressure plate 5 moves downward, thereby forming the first ear piece 51 and the second ear piece 55 at the designated position of the bottom box 12. The lower pressure plate 5 is also provided with multiple slots that cooperate with the through-blade 7 and the mold blade 8. The through-blade 7 and the mold blade 8 are respectively installed in the corresponding slots and can move up and down on the inner wall of the slot. That is, after the lower pressure plate 5 moves downward and presses and fixes the bottom box 12, when the upper pressure plate 4 continues to move downward, the corresponding through-blade 7 and mold blade 8 can punch the bottom box 12 to form the required shape, and the punched waste will fall downward into the designated position.

[0046] The clamping mechanism also includes multiple clamping seats 18 that are slidably connected to the mold table 11. The clamping rods 27 are slidably connected to the inner walls of the clamping seats 18. Square bases 24 are slidably connected to the inner walls of the bottom ends of the clamping seats 18. First movable pins 25 are fixedly connected to the inner walls of the square bases 24. Multiple guide plates 28 are fixedly connected to the lower surface of the mold table 11. Short horizontal grooves 30 and short oblique grooves 29 that cooperate with the first movable pins 25 are respectively opened on the guide plates 28. Second springs 26 that cooperate with the clamping rods 27 are fixedly connected to the upper surface of the square bases 24.

[0047] like Figures 9-12 As shown, the clamping seat 18 can slide left and right or back and forth on the inner wall of the mold table 11, the clamping rod 27 can slide up and down on the inner wall of the clamping seat 18, and the square base 24 can slide up and down on the inner wall of the clamping seat 18. The installation and shape of the square base 24, the first live pin 25, and the guide plate 28 are as follows. Figure 11 or Figure 12 As shown, the second spring 26 can support the clamping rod 27 under normal conditions, and the upper end of the second spring 26 is fixed to the clamping rod 27; side plates 13 are fixed to the left and right sides of the lower surface of the mold table 11, respectively, and the side plates 13 are fixed to the upper surface of the operating table 1. The side plates 13 are used to support and fix the mold table 11; when the clamping seat 18 moves inward, it can drive the clamping rod 27, the square base 24, the first movable pin 25, etc. to move inward synchronously. When the first movable pin 25 moves inward, under the engagement of the first movable pin 25 and the short inclined groove 29, the first movable pin 25, the square base 24, the second spring 26, the clamping rod 27, etc. can move upward synchronously. When the clamping rod 27 moves upward, it can move out to the upper surface of the clamping seat 18. When the clamping seat 18, the first movable pin 25, etc. continue to move inward, that is, when the first movable pin 25 moves inward and enters the inner wall of the short transverse groove 30, the first movable pin 25, the square base 24, etc. will only move horizontally inward. At this time, the clamping rod 27 moves upward to the top position and moves horizontally inward with the clamping seat 18. When the clamping rod 27 moves inward, it can perform center calibration and clamp and fix the bottom box 12. When the pressure plate 5 moves downward to press and fix the bottom box 12, the pressure plate 5 can contact the clamping rod 27. The downward movement of the pressure plate 5 will also press the clamping rod 27 downward. When the clamping rod 27 moves downward, it will press the second spring 26. Through the second spring 26, the clamping rod 27 can be clamped without affecting the calibration and clamping of the bottom box 12, and without affecting the downward pressing of the bottom box 12 by the pressure plate 5. When the clamping seat 18 moves outward, the first live pin 25, the clamping rod 27, etc. can move outward to reset. The clamping rod 27 will move downward into the inner wall of the clamping seat 18 under the engagement of the short inclined groove 29 and the first live pin 25. At this time, the clamping rod 27 is lower than the upper end face of the mold table 11. When placing the next bottom box 12 for processing, it will not affect the operation of placing the bottom box 12.

[0048] The mold table 11 has a rotatable first disk 14 at the lower center. The lower surface of the first disk 14 is hinged with two centrally symmetrical first connecting rods 17. The clamping seat 18 includes two first clamping seats and two second clamping seats. The outer ends of the two first connecting rods 17 are respectively hinged to the corresponding first clamping seats. The lower surface of the first clamping seats is fixed with a first connecting plate 19. The lower surface of the second clamping seats is fixed with a second connecting plate 23. The front and rear ends of the second connecting plate 23 are respectively fixed with square guide plates 21. The left and right sides of the lower surface of the first connecting plate 19 are respectively fixed with first sliding pins 20. The square guide plates 21 are respectively provided with oblique keyways 22 that cooperate with the first sliding pins 20.

[0049] like Figures 8-10As shown, the first clamping seats are arranged front and rear on the mold table 11, and the second clamping seats are arranged left and right on the mold table 11. When the first disc 14 rotates, the two first clamping seats can be driven to move synchronously inward or outward through the hinge of the first connecting rod 17 and the first clamping seats. The first connecting plate 19, the second connecting plate 23, the square guide plate 21, and the first sliding pin 20 are installed and shaped as follows. Figure 9 or Figure 10 As shown, when the first clamping seat moves inward or outward, it can drive the first connecting plate 19 to move inward or outward. When the first connecting plate 19 moves inward, it can also drive the first sliding pin 20 to move inward. When the first sliding pin 20 moves inward, it will drive the square guide plate 21 and the second connecting plate 23 to move inward through engagement with the inclined keyway 22. When the second connecting plate 23 moves inward, it can also drive the second clamping seat to move inward. Therefore, when the first disc 14 rotates, it can drive the first clamping seat and the second clamping seat to move inward or outward synchronously. Through the cooperation of the first disc 14, the first connecting plate 19, the second connecting plate 23, etc., the operation of the clamping mechanism can be controlled without affecting the falling of the residual material after punching.

[0050] A spur gear 15 is coaxially fixed to the upper end of the first disk 14. A spur rack 16 meshes on the outer surface of the spur gear 15. A first drive plate 31 is fixed to the front end surface of the second spur rack 16. A first drive pin 32 is fixed to one end face of the drive arm 3. A long oblique groove 33 and a long vertical groove 34 that cooperate with the first drive pin 32 are provided on the first drive plate 31.

[0051] like Figure 9 or Figure 13As shown, a rotating shaft is fixed to the inner wall of the center of the spur gear 15 and the first disk 14. The rotating shaft is rotatably connected to the lower surface of the mold table 11, limiting the spur gear 15 and the first disk 14 to rotate only. The front end of the rack 16 passes through and is slidably connected to the inner wall of the vertical plate 2. The first drive plate 31 is slidably connected to the operating table 1. When the first drive plate 31 moves back and forth, it can drive the rack 16 to move back and forth, and the spur gear 15 and the first disk 14 to rotate, that is, control the clamp 18 to move inward or outward. When the drive arm 3 moves downward, it can drive the first drive pin 32 to move downward. When the first drive pin 32 moves downward, it can drive the first drive plate 31 to move backward through meshing with the long inclined groove 33. When the first drive plate 31 moves backward, it can drive the first disk 14 to rotate. When the disc 14 rotates, the corresponding clamp 18 will move inward, so that the clamping rod 27 is aligned with the bottom box 12 and clamped and fixed. When the drive arm 3, the first drive pin 32 and the others move downward and enter the inner wall of the long vertical groove 34, the drive arm 3 and the first drive pin 32 continue to move downward and no longer drive the first drive plate 31 to move backward. That is, the corresponding clamping rod 27 is in the innermost end and clamps and fixes the bottom box 12. At this time, the drive arm 3 continues to move downward and can drive the punching mechanism to work. That is, the clamping mechanism can first work to align and fix the bottom box 12, and then the punching mechanism can work to punch the bottom box 12. This process is repeated. When the drive arm 3 and the first drive pin 32 move upward and reset, the corresponding clamping mechanism will move outward and reset under the engagement of the first drive pin 32 and the long inclined groove 33.

[0052] The upper surface of the operating table 1 is slidably connected to a second drive plate 41 that can move back and forth. The upper surface of the operating table 1 is also slidably connected to a support 35. The support 35 is fixed to the front end of the second drive plate 41, and a collection box 36 is placed on the upper end of the support 35.

[0053] like Figure 14 As shown, the second drive plate 41 and the support 35 can be slidably connected to the operating table 1. When the second drive plate 41 moves back and forth, it can drive the support 35 and the collection box 36 to move back and forth. The collection box 36 is used to load the residual material after punching for centralized recycling. When the second drive plate 41 moves back and forth in an oscillating motion, it can drive the collection box 36 to move back and forth in an oscillating motion, so that the residual material in the collection box 36 is evenly loaded, holding more residual material and extending the replacement cycle.

[0054] A cylindrical seat 38 is fixedly connected to the other end face of the drive arm 3. A second drive pin 40 is slidably connected to the inner wall of the cylindrical seat 38. A third spring 39 that cooperates with the second drive pin 40 is fixedly connected to the inner wall of the bottom end of the cylindrical seat 38. A first vertical groove 42, a first inclined groove 43, a wave groove 44 and a second inclined groove 45 that cooperate with the second drive pin 40 are provided on the second drive plate 41.

[0055] like Figures 15-17As shown, the cylindrical seat 38 is used to install the second drive pin 40. The third spring 39 always exerts a leftward driving force on the second drive pin 40, so that the second drive pin 40 is in the extended state under normal conditions. That is, the second drive pin 40 can stably engage with the first vertical groove 42, the first inclined groove 43, the wave groove 44, and the second inclined groove 45 under normal conditions. When the second drive pin 40 moves downward on the inner wall of the first vertical groove 42, the second drive pin 40 will not drive the second drive plate 41 to move forward or backward. When the second drive pin 40 moves upward on the inner wall of the first inclined groove 43, the second drive plate 41 will move backward. When the second drive pin 40 moves upward in the wave groove 44... When the wall moves upward, the second drive plate 41 will oscillate back and forth. When the second drive pin 40 moves upward on the inner wall of the second inclined groove 45, the second drive plate 41 will move backward to reset. A first wedge block 46 is fixed to the inner wall of the lower end of the first vertical groove 42, and a second wedge block 47 is fixed to the inner wall of the second inclined groove 45. One end of the first wedge block 46 and the second wedge block 47 are respectively provided with an inclined surface 48, and the other end is respectively provided with a straight surface 49. Through the first wedge block 46 and the second wedge block 47, the second drive pin 40 can slide in one direction. That is, when the second drive pin 40 moves downward on the inner wall of the first vertical groove 42, it will first move backward to reset. When the inclined surfaces 48 of the first wedge block 46 meet, the second drive pin 40 is engaged with the inclined surface 48 of the first wedge block 46, allowing the second drive pin 40 to move slightly to the right and enter the inner wall of the cylindrical seat 38, thus compressing the third spring 39. When the second drive pin 40 moves downward and enters the inner wall of the first inclined groove 43, it disengages from the first wedge block 46. Under the force of the third spring 39, the second drive pin 40 moves to the left and pops back to its original position, meaning the left end face of the second drive pin 40 contacts the bottom wall of the first inclined groove 43. At this point, when the second drive pin 40 moves upward, it is blocked by the straight surface 49 of the first wedge block 46. The second drive pin 40 can move along the inner wall of the first inclined groove 43, thus preventing the second drive pin 40 from accidentally entering the inner wall of the first vertical groove 42 when moving upward. Similarly, when the second drive pin 40 moves upward along the inner wall of the second inclined groove 45, the second wedge block 47 can prevent the second drive pin 40 from accidentally entering the inner wall of the second inclined groove 45 when moving downward along the inner wall of the first vertical groove 42. In other words, with the cooperation of the first wedge block 46, the second wedge block 47 and the second drive pin 40, the second drive pin 40 can move unidirectionally and cyclically along the first vertical groove 42, the first inclined groove 43, the wave groove 44 and the second inclined groove 45.Furthermore, in coordination with the drive arm 3, when the drive arm 3 moves downward, it drives the second drive pin 40 to move downward. The second drive pin 40 then moves downward along the inner wall of the first vertical groove 42. At this time, the second drive plate 41 does not move back and forth, meaning that during the punching process, the excess material can fall into the collection box 36. When the drive arm 3 moves downward to the bottom, the punching mechanism completes the punching, and the second drive pin 40 moves downward into the inner wall of the first inclined groove 43. When the drive arm 3, the second drive pin 40, etc., move upward to reset, the second drive pin 40 can drive the second drive plate 41 to move backward. When the second drive pin 40 continues to move upward... When the device moves to the inner wall of the wave groove 44, it can drive the second drive plate 41 to move back and forth with a small amplitude oscillation, that is, drive the collection box 36 to move with a small amplitude oscillation, shaking the remaining material in the collection box 36 evenly. When the drive arm 3 and the second drive pin 40 continue to move upward, they can enter the inner wall of the second inclined groove 45. At this time, the second drive plate 41 can move forward. When the second drive pin 40 moves upward to enter the inner wall of the first vertical groove 42, the second drive plate 41 and the collection box 36 can move forward to the initial position to reset. This cycle can be repeated continuously, and the device can shake evenly once after each punching, so that the collection box 36 can hold more remaining material and extend the replacement cycle.

[0056] In use, this invention allows for folding of the short fold 56, long fold 57, wide fold 58, and narrow fold 62 via the set pressure lines. When the short fold 56 is folded vertically upwards along the pressure lines, the first ear piece 51 can be fastened into the corresponding first slot 50, preventing the folded short fold from unraveling and thus keeping it stable. By bending the first hanging piece 52 and the second hanging piece 53, the first hanging piece 52 and the second hanging piece 53 can be fastened into the corresponding first slot 50, connecting and fixing the folded short fold 56 and long fold 57. With the cooperation of the slot 50, the overall stability of the bottom box 12 structure can be improved, and the short folded edge 56 and the long folded edge 57 have a double layer after folding, which prevents deformation and damage during transportation. With the preparation device, when the punching mechanism moves down to punch, the bottom box 12 can be cut into the required shape. With the clamping mechanism, i.e., multiple clamping rods 27, when the drive arm 3 moves down, the clamping rods 27 can first move inward to center the bottom box 12 and then clamp and fix it to prevent movement. Then the punching mechanism can move down to the designated position to punch the bottom box 12, thereby processing the required shape.
