Description

Technical Field

[0001] This invention relates to the field of packaging box processing technology, specifically a packaging box die-cutting and waste removal equipment. Background Technology

[0002] Currently, in the process of processing packaging boxes, to improve production efficiency, multiple packaging box patterns are usually arranged simultaneously on the same sheet of printed paper. These are then cut according to the preset patterns using cutting equipment, thus obtaining the outlines of multiple packaging boxes at once. This process typically relies on die-cutting. After die-cutting, although the finished packaging box is cut off from the surrounding waste material, it is often still connected by several tiny connection points or waste areas, and is not completely separated. To obtain a complete unfolded packaging box, a waste removal operation must be performed, that is, by manually pressing or using mechanical equipment to apply pressure to completely separate the waste material from the product.

[0003] Currently, there are two main implementation methods for the waste removal process after die-cutting: one is manual separation using simple handheld waste removal tools; the other is mechanized processing using pin-type automatic waste removal equipment. However, existing automatic waste removal devices still have certain limitations in practical applications. Specifically, these devices mostly rely on manual loading during processing. After the equipment completes a waste removal operation, separating the product from the waste edge, the operator needs to remove the finished product from the work area and then manually clean up the accumulated waste before proceeding to the next round of loading and processing. This operating mode results in a long downtime for material handling and waste removal in each processing cycle, making continuous and efficient automated production impossible.

[0004] Based on this, a packaging box die-cutting waste removal device is now provided, which can eliminate the drawbacks of existing devices. Summary of the Invention

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention achieves a streamlined, cyclical operation of material loading, waste removal, and waste discharge by setting up intermittently rotating bearing components and sequentially distributed feeding, waste removal, and waste discharge bottom boxes along the rotation direction. The equipment drives the rotating disc to rotate intermittently by 90 degrees via a reducer motor, allowing the bearing plate to pass through each workstation in sequence. Combined with external automatic feeding and unloading components, this greatly reduces the frequency of manual intervention. Compared with traditional equipment that requires stopping to wait for material loading and unloading, this solution achieves continuous processing, significantly shortens the production cycle, and improves the overall efficiency and automation of waste removal processing.

[0015] 2. This invention achieves automatic clamping and fixing of material plates through the linkage of the top rod, the pushing plate, and the guide block in the clamping mechanism, combined with the self-locking structure of the elastic telescopic rod and the fixed guide block. When the bearing plate is in the loading station or the processing station, the clamping frame can stably press the stacked packaging box material plates, effectively preventing the material plates from being misaligned due to inertia or vibration during the transfer process, thereby ensuring the accuracy of subsequent waste removal processing. At the same time, the cooperative design of the elastic telescopic rod and the sliding guide block, together with the action of the first tension spring, allows the waste material to be automatically released from fixation when it reaches the discharge station, which not only ensures the stability of the transfer but also simplifies the unloading operation.

[0016] 3. This invention features a specialized pushing component designed for waste removal at the discharge station. A second motor drives a threaded rod to move a sliding frame and a mounting rod, allowing the pushing needle to precisely insert into the notch in the middle of the waste and push it out. During this process, the cooperation of rollers and guide frames ensures that the pushing needle moves smoothly and accurately when contacting the waste, avoiding damage to the equipment or residual waste caused by hard contact. In addition, the pushing needles can be arrayed according to the shape of waste from different packaging boxes, exhibiting strong versatility and adaptability. This enables efficient and thorough automatic waste removal, preparing the material for the next round of feeding. Attached Figure Description

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. Example 1

[0030] In one embodiment, such as Figures 1-11As shown, a packaging box die-cutting and waste removal device includes a processing table 11 and a mounting turntable 13. A fixed box 12 is fixedly installed at the bottom center of the processing table 11. The mounting turntable 13 is located above the middle of the processing table 11. One end of the drive shaft at the bottom of the mounting turntable 13 extends into the fixed box 12. A plurality of bearing components 14 are arranged in an array on the mounting turntable 13. A feeding bottom box 16, a waste removal bottom box 17, and a discharging bottom box 19 are sequentially arranged at the bottom of the processing table 11 along the rotation direction of the mounting turntable 13. A bearing is installed on the drive shaft and is installed inside the upper part of the fixed box 12. The end of the drive shaft is fixedly connected to the drive end of a reducer motor 15, which is installed inside the fixed box 12. The bottom of the processing table 11 is fixedly connected to the fixed box 12, the loading bottom box 16, the waste cleaning bottom box 17 and the discharge bottom box 19 by a reinforcing frame. The upper end of the processing table 11 is fixedly provided with an upper frame 21, and an outer protective cover 22 is fixedly provided on the outside of the upper frame 21. A material unloading component 18 is provided above the processing table 11 at a position corresponding to the waste cleaning bottom box 17. The bearing component 14 includes a bottom frame 23, and a connecting frame 24 is fixedly provided at the end of the bottom frame 23. The connecting frame 24 is fixedly provided on the mounting turntable 13. A bearing plate 25 is fixedly provided at the upper end of the bottom frame 23. A plurality of first waste cleaning holes are arrayed on the upper end of the bearing plate 25. A clamping mechanism for clamping and fixing the material plate is provided at the upper end of the bearing plate 25. The clamping mechanism clamps and fixes the material plate to prevent misalignment during material plate transfer. The unloading component 18 facilitates the cleaning and waste removal of the material plate. When the packaging box material plate needs to be cleaned, the reducer motor 15 drives several bearing components 14 to rotate intermittently through the mounting turntable 13. When the bearing components 14 rotate to the top of the loading base box 16, the external loading component places the stacked packaging box material plate on the top of the bearing plate 25. Then, the clamping mechanism clamps and fixes the packaging box material plate. Then, the reducer motor 15 rotates intermittently by 90 degrees again, so that the material plate rotates to the bottom of the unloading component 18. The unloading component 18 cleans the packaging box material plate. The external unloading component removes the cleaned packaging box material plate. When the reducer motor 15 drives the bearing component 14 to rotate again, the bearing component 14 drives the waste material to rotate to the top of the discharge base box 19. Then, the waste material on the top of the bearing plate 25 is removed, thus completing the cleaning and waste removal of the packaging box material plate.

[0031] The clamping mechanism includes clamping frames 26. Clamping frames 26 are symmetrically arranged above the support plate 25. Each clamping frame 26 is slidably disposed inside a first fixing tube 27, which is fixedly disposed on the upper end of the support plate 25. A nut block is fixedly disposed at the end of each first fixing tube 27. Two nut blocks are mounted on a bidirectional screw 28, which is rotatably disposed inside a second fixing tube 29. Torsion blocks are fixedly disposed at both ends of the bidirectional screw 28. A stop wheel 30 is fixedly disposed in the middle of the bidirectional screw 28, and a stop block 31 is fitted onto the stop wheel 30. The stop block 31 is rotatably disposed at the end of a screw, which is rotatably disposed in a threaded hole at the upper end of the second fixing tube 29. First guide slides are symmetrically arranged on one side of each clamping frame 26. The first guide slides are slidably disposed... In the sliding hole on one side of the first fixed tube 27, a first return spring 35 is provided between one end of the first guide slide rod and one side of the first fixed tube 27. A plurality of guide blocks 32 are arrayed on one side of the clamping frame 26. One end of the guide block 32 is inclined. A push seat 33 is provided at one end of the guide block 32. The push seat 33 is fixed on the push plate 34. The push plate 34 is slidably disposed inside the first fixed tube 27. A top rod 37 is fixed at one end of the push plate 34. A limiting plate is fixed on one side of the push plate 34. A fourth fixed tube is provided on one side of the first fixed tube 27 at a position corresponding to the position of the limiting plate. A first tension spring 36 is provided between one side of the limiting plate and one end of the fourth fixed tube. A limiting component for fixing the push plate 34 is provided at the upper end of the first fixed tube 27.

[0032] The limiting component includes an elastic telescopic rod 38. Each end of the push plate 34 is fixedly provided with an elastic telescopic rod 38. The telescopic end of the elastic telescopic rod 38 is inclined. A fixed guide block 39 is fitted to the end of the elastic telescopic rod 38. The fixed guide block 39 is fixedly mounted on a second guide slide rod. The second guide slide rod is fixedly mounted inside a third fixed tube 42. The third fixed tube 42 is installed on the upper end of the first fixed tube 27. A sliding guide block 40 is slidably mounted on the second guide slide rod. A second tension spring 41 is provided between one side of the sliding guide block 40 and one side of the interior of the third fixed tube 42. A limiting rod is tightly attached to one side of the sliding guide block 40. The limiting rod is fixed... Inside the third fixed tube 42, a first guide plate 45 is provided both inside the feeding base box 16 and at the end of the top rod 37. The ends of the first guide plates 45 are inclined. The first guide plates 45 are all installed on the upper end of the first connecting plate. The first connecting plate is installed on the telescopic end of the first electric cylinder 46. The first electric cylinder 46 is installed inside the feeding base box 16. Inside the discharging base box 19, a second guide plate 55 is provided both inside and at the working end of the top rod 37. The second guide plates 55 are all installed on the upper end of the second connecting plate. The second connecting plate is fixedly installed on the telescopic end of the fifth electric cylinder 56. The fifth electric cylinder 56 is installed inside the discharging base box 19.

[0033] When the clamping frame 26 needs to clamp and fix the packaging box material plate, the pusher plate 34 is moved a fixed distance by the push rod 37. During this process, the elastic telescopic rod 38 cooperates with the end of the fixed guide block 39 to extend and retract. When the pusher plate 34 stops moving, one side of the elastic telescopic rod 38 is in close contact with one side of the fixed guide block 39, thereby fixing the pusher plate 34. During the movement of the pusher plate 34, the pusher plate 34 pushes the guide block 32 to slide through several pusher seats 33. 2. The clamping frame 26 slides, thereby clamping and fixing the packaging box material plate. When it is necessary to release the fixing of the waste material, push the top rod 37 to slide a fixed distance again. Under the action of the limit rod, the telescopic end of the elastic telescopic rod 38 retracts, so that the end of the elastic telescopic rod 38 is located at the inclined end of the sliding guide block 40. Then, release the top rod 37. Under the action of the first tension spring 36, the push plate 34 slides in the initial direction. At the same time, the elastic telescopic rod 38 pulls the sliding guide block 40 to slide. One side of the sliding guide block 40 is connected to the fixed guide. When block 39 is pressed against one side, the telescopic end of the elastic telescopic rod 38 extends and retracts. As the push plate 34 continues to move, the end of the elastic telescopic rod 38 is pressed against the end of the fixed guide block 39. Subsequently, the end of the elastic telescopic rod 38 separates from the fixed guide block 39. Under the action of the first return spring 35, the clamping frame 26 moves into the first fixed tube 27, thereby releasing the fixation of the waste material. After the upper end of the bearing plate 25 is fully loaded, the first electric cylinder 46 is started. The output end of the first electric cylinder 46 drives the first guide plate 45. As the material rises, when the inclined end of the first guide plate 45 is in close contact with the top rod 37, the first guide plate 45 guides the top rod 37, causing the top rod 37 to move the push plate 34 a fixed distance. When the waste material moves above the discharge bottom box 19, the fifth electric cylinder 56 is activated. The fifth electric cylinder 56 drives the second guide plate 55 to move. The inclined end of the second guide plate 55 guides the top rod 37, causing the top rod 37 to move again. Subsequently, when the second guide plate 55 moves into the discharge bottom box 19, the clamping frame 26 releases its fixation on the waste material.

[0034] The unloading component 18 includes a first mounting plate 47 and a second mounting plate 50. The first mounting plate 47 is disposed inside the waste removal bottom box 17 and is mounted on the telescopic end of the second electric cylinder 49. The upper end of the first mounting plate 47 and the first waste removal hole are provided with a first threaded hole, in which a first ejector pin 48 is installed. The upper end of the processing table 11 and the first threaded hole are both provided with second waste removal holes. The lower end of the second mounting plate 50 and the first threaded hole are both provided with second threaded holes, in which a second ejector pin 51 is installed. The second mounting plate 50 is fixedly connected to the telescopic end of the third electric cylinder 52. Next, the third electric cylinder 52 is installed inside the mounting bracket, which is fixedly installed inside the upper frame 21. The bottom end of the second mounting plate 50 is closely attached to the lower pressure plate 53. The bottom end of the lower pressure plate 53 and the second threaded hole are both provided with a third waste cleaning hole. The lower pressure plate 53 is fixedly connected to the telescopic ends of two fourth electric cylinders 54. The fourth electric cylinders 54 are all installed inside the mounting bracket. A light curtain assembly is provided on the outer protective cover 22 above the waste cleaning bottom box 17. The light curtain assembly, the second electric cylinder 49, the third electric cylinder 52 and the fourth electric cylinder 54 are all electrically connected to the controller 57. The controller 57 is installed inside the mounting bracket. Mounted at the bottom of the processing table 11, during use, the supporting component 14 moves the packaging box material plate to below the second mounting plate 50. Then, the controller 57 controls the third electric cylinder 52 and the fourth electric cylinder 54 to start. After the end of the second ejector pin 51 is in close contact with the waste material, the extension end of the third electric cylinder 52 stops extending. After the bottom end of the lower pressure plate 53 is in close contact with the upper end of the packaging box material plate, the extension end of the fourth electric cylinder 54 stops extending. Subsequently, the controller 57 controls the second electric cylinder 49 to start. The second electric cylinder 49 drives the first ejector pin 48 to rise through the first mounting plate 47. When the end of the first ejector pin 48 is in close contact with the finished packaging box, the extension end of the fourth electric cylinder 54 retracts. The retraction causes the lower pressure plate 53 and the first ejector pin 48 to move synchronously, separating the finished packaging box from the waste. When the upper end of the lower pressure plate 53 is in close contact with the bottom end of the second mounting plate 50, the extension end of the second electric cylinder 49 stops extending, and the extension end of the third electric cylinder 52 extends and retracts, causing the second mounting plate 50 and the lower pressure plate 53 to rise synchronously. The first ejector pin 48 lifts the finished packaging box, and the external material handling component removes the finished packaging box. Then, the extension end of the second electric cylinder 49 retracts. It is worth noting that the number of first ejector pins 48 and second ejector pins 51 installed in this application needs to be installed according to the shape of the finished packaging box and the waste. The figure is only a schematic diagram of the installation. Example 2

[0035] The difference from Embodiment 1 is that: a pushing component 20 is provided above the processing table 11 at a position corresponding to the discharge bottom box 19. The pushing component 20 includes a mounting rod 59, and the bottom end of the mounting rod 59 is provided with a plurality of third threaded holes. A pushing pin 58 is installed in the third threaded holes. A sliding frame 60 is fixedly provided at the upper end of the mounting rod 59. A driving block 61 is slidably provided on the sliding frame 60. The driving block 61 is provided with a fourth threaded hole and a sliding hole in the middle. A threaded rod 62 is fitted in the fourth threaded hole. The threaded rod 62 is rotatably disposed inside the mounting box 67. A third guide slide rod is slidably disposed in the sliding hole. The third guide slide rod is fixedly disposed inside the mounting box 67. The mounting box 67 is installed inside the upper frame 21. The end of the threaded rod 62 is fixedly connected to the output end of the second motor 63. The second motor 63 is installed at the end of the mounting box 67. Fixed shafts are symmetrically provided at the end of the sliding frame 60. Rollers 64 are installed at the ends of the fixed shafts. Guide frames 65 are fitted on the rollers 64. The guide frames 65 are slidably disposed inside the mounting box 67. The end of the mounting box 67 is fixedly connected to the telescopic end of the sixth electric cylinder 66. The sixth electric cylinder 66 is installed on the upper end of the mounting box 67. In use, after the bearing component 14 moves the waste material to above the discharge bottom box 19, the second motor 63 is started. The second motor 63 drives the threaded rod 62 to rotate. Under the action of the thread, the drive block 61 moves the mounting rod 59 through the sliding frame 60. At the same time, the rollers 64 are in close contact with the upper end of the guide frame 65. The rollers 64 change synchronously with the shape of the upper end of the guide frame 65. When the rollers 64 are in close contact with the lowest point of the guide frame 65, the pusher needle 58 is inserted into the middle notch of the waste material. The bottom end of the pusher needle 58 is in close contact with the upper end of the bearing plate 25. As the pusher needle 58 moves, it drives the waste material to move, thereby removing the waste material from the upper end of the bearing plate 25. Example 3

[0036] The difference from Embodiment 1 is that: a number of support rods 43 are fixedly provided at the bottom end of the bottom frame 23, and each support rod 43 is provided with a ball bearing at its end. A limiting ring 44 is provided at the upper end of the processing table 11 and at the end of the support rod 43. In use, the support rods 43 can easily support the bottom frame 23, thereby preventing the bottom frame 23 from deforming during transportation.

[0037] The above embodiment discloses a packaging box die-cutting waste removal device. When waste removal of the packaging box material plates is required, the reducer motor 15 drives several supporting components 14 to rotate intermittently via the mounting turntable 13. When the supporting components 14 rotate above the loading base box 16, the external loading component places the stacked packaging box material plates on the upper end of the supporting plate 25. The first electric cylinder 46 is then activated, and its output drive causes the first guide plate 45 to rise. When the inclined end of the first guide plate 45 is in close contact with the top rod 37, the first guide plate 45... 7. The top rod 37 guides the push plate 34 to move a fixed distance. During this process, the elastic telescopic rod 38 cooperates with the end of the fixed guide block 39 to extend and retract. When the push plate 34 stops moving, one side of the elastic telescopic rod 38 is in close contact with one side of the fixed guide block 39, thereby fixing the push plate 34. During the movement of the push plate 34, the push plate 34 pushes the guide block 32 to slide through several push seats 33. The guide block 32 drives the clamping frame 26 to slide, thereby clamping and fixing the packaging box material plate. After the supporting component 14 moves the packaging box material plate to below the second mounting plate 50, the controller 57 controls the third electric cylinder 52 and the fourth electric cylinder 54 to start. After the end of the second ejector pin 51 is in close contact with the waste material, the extension end of the third electric cylinder 52 stops extending. After the bottom end of the lower pressure plate 53 is in close contact with the upper end of the packaging box material plate, the extension end of the fourth electric cylinder 54 stops extending. Then, the controller 57 controls the second electric cylinder 49 to start. The second electric cylinder 49 drives the first ejector pin 48 to rise through the first mounting plate 47. The end of the first ejector pin 48 is in close contact with the packaging box material plate. When the finished packaged box is tightly attached, the telescopic end of the fourth electric cylinder 54 retracts, causing the lower pressure plate 53 and the first ejector pin 48 to move synchronously, thus separating the finished packaged box from the waste material. When the upper end of the lower pressure plate 53 is tightly attached to the bottom end of the second mounting plate 50, the telescopic end of the second electric cylinder 49 stops extending, and the telescopic end of the third electric cylinder 52 extends and retracts, causing the second mounting plate 50 and the lower pressure plate 53 to rise synchronously. The first ejector pin 48 lifts the finished packaged box, and the external material handling component removes the finished packaged box. Then, the telescopic end of the second electric cylinder 49 retracts. After the supporting component 14 moves the waste material above the discharge bottom box 19, the fifth electric cylinder 56 is activated. The fifth electric cylinder 56 moves the second guide plate 55. The inclined end of the second guide plate 55 guides the top rod 37, causing the top rod 37 to move again. Under the action of the limit rod, the telescopic end of the elastic telescopic rod 38 retracts, so that the end of the elastic telescopic rod 38 is located at the inclined end of the sliding guide block 40. When the second guide plate 55 moves into the discharge bottom box 19, under the action of the first tension spring 36, the push plate 34 slides in the initial direction. At the same time, the elastic telescopic rod 38 pulls the sliding guide block 40 to slide. When one side of the sliding guide block 40 is in close contact with one side of the fixed guide block 39, the telescopic end of the elastic telescopic rod 38 extends and retracts. As the push plate 34 continues to move, the end of the elastic telescopic rod 38 is in close contact with the end of the fixed guide block 39. After the material is attached, the end of the elastic telescopic rod 38 separates from the fixed guide block 39. Under the action of the first return spring 35, the clamping frame 26 moves into the first fixed tube 27, thereby releasing the fixation of the waste material. The second motor 63 is started, and the second motor 63 drives the threaded rod 62 to rotate. Under the action of the thread, the drive block 61 drives the mounting rod 59 to move through the sliding frame 60. At the same time, the roller 64 is tightly attached to the upper end of the guide frame 65. The roller 64 changes synchronously with the shape of the upper end of the guide frame 65. When the roller 64 is tightly attached to the lowest point of the guide frame 65, the pusher needle 58 is inserted into the middle notch of the waste material. The bottom end of the pusher needle 58 is tightly attached to the upper end of the support plate 25. As the pusher needle 58 moves, it drives the waste material to move, thereby removing the waste material from the upper end of the support plate 25, thus completing the waste removal of the packaging box material plate.
