Description

Technical Field

[0001] The utility model relates to the technical field of carton processing and installation, in particular to an embossing device for carton processing. Background Technique

[0002] Carton packaging largely promotes and beautifies products with its delicate shapes and decorations, enhancing the competitiveness of products. Since the shapes and structural designs of cartons are often determined by the shapes of the products to be packaged, embossing is required during carton processing to distinguish product types. As the name implies, embossing is a forming method in which the end face of a die is pressed into a blank, causing the patterns or words on the embossing die to be pressed onto the blank. Therefore, embossing equipment is needed.

[0003] When processing cartons by embossing, especially when pressing patterns or words on the embossing die onto the blank, it is difficult for the embossing die to quickly and accurately align with the embossing position of the carton blank, resulting in a relatively long time wasted in adjusting the embossing position. This not only easily causes embossing deviations but also affects embossing efficiency. Moreover, different types of carton blanks require different patterns or words to be embossed, so various specifications of embossing dies are often needed. However, most existing equipment only has one embossing die. When other specifications of embossing dies are required, it is necessary to disassemble and replace them tediously through bolts, and the operation is very inconvenient.

Specific implementation method

[0026] An embossing device for processing paper boxes:

[0027] As Figure 1-4 shown, in this embodiment, it includes a machine body 1 and a concave embossing table 2. The concave embossing table 2 is fixed at the lower end inside the machine body 1. Above the concave embossing table 2, there is an embossing disc 7. A number of embossing dies 8 are arranged around the embossing disc 7. At the left end inside the concave embossing table 2, there is a positioning plate 3. The left side of the positioning plate 3 is rotatably connected with a threaded adjusting rod 4. The threaded adjusting rod 4 threads through the left side of the concave embossing table 2 to the left. The left side of the positioning plate 3 is fixed with a guide rod 5. The guide rod 5 slides through the left side of the concave embossing table 2 to the left.

[0028] When processing paper boxes with this embossing device, according to the left and right widths of the paper box blank, adjust the use position of the positioning plate 3. Therefore, turn the threaded adjusting rod 4 to drive the positioning plate 3 to move left and right. The positioning plate 3 will drive the guide rod 5 to slide left and right along the concave embossing table 2 until the distance between the right end of the positioning plate 3 and the right inner wall of the concave embossing table 2 is consistent with the left and right width of the paper box blank. Then, place the paper box blank on the concave embossing table 2, and the paper box blank is located at the right end of the positioning plate 3. Therefore, the paper box blank can be quickly positioned correctly on the concave embossing table 2 for subsequent embossing.

[0029] As Figure 1-3 shown, in this embodiment, an electric cylinder 10 is provided above the stamper 7. A concave frame 6 is connected to the power end of the electric cylinder 10. A rectangular laser light strip 16 connected to the outer surface of the stamper 7 is sleeved around the periphery of the stamping die 8. A guide shaft 13 is fixed to the upper end inside the machine body 1. A sliding block 9 is slidably sleeved around the guide shaft 13. The electric cylinder 10 is fixed to the lower end of the sliding block 9. A positive and negative motor 11 is fixed to the upper right end of the inner wall of the machine body 1. A lead screw 12 is connected to the power end of the positive and negative motor 11. The lead screw 12 passes through the sliding block 9 in a left-handed thread, and the end of the lead screw 12 is rotatably connected to the left inner wall of the machine body 1.

[0030] By arranging a rectangular laser light strip 16 around the periphery of the stamping die 8, on the premise that the storage battery 26 is set in series with the rectangular laser light strip 16, and when the lowermost rectangular laser light strip 16 is energized to work, the light emitted by the rectangular laser light strip 16 projects a rectangular pattern on the paperboard blank. The staff can push the paperboard blank back and forth to adjust the front and back positions of the light projection. Moreover, by the operation of the positive and negative motor 11, the lead screw 12 is driven to rotate. The lead screw 12 will drive the sliding block 9 to slide left and right along the guide shaft 13. The sliding block 9 will drive the electric cylinder 10, the concave frame 6, the stamper 7 and the stamping die 8 to move left and right. Therefore, the position of the light emitted by the rectangular laser light strip 16 projected on the paperboard blank can be conveniently adjusted. The projected rectangular pattern is the stamping position of the stamping die 8, so that the stamping die 8 can be accurately aligned with the position to be stamped on the paperboard blank, effectively saving the time for adjusting the stamping. Moreover, by the elongation of the electric cylinder 10, the concave frame 6, the stamper 7 and the stamping die 8 are driven to move downward, and then the stamping die 8 can accurately perform stamping processing on the paperboard blank, which is beneficial to ensuring the stamping accuracy and stamping efficiency.

[0031] As Figure 5 、 6 shown, in this embodiment, the stamper 7 is rotatably connected to the inside of the concave frame 6. A rotation braking assembly is provided inside the concave frame 6. The rotation braking assembly includes a braking motor 21, a PLC controller 22, a main gear 23, a rotating shaft 24 and a sub-gear 25. The braking motor 21 and the PLC controller 22 are both fixed to the inner side wall of the concave frame 6. The main gear 23 is connected to the power end of the braking motor 21. One end of the rotating shaft 24 is fixed to the middle of the stamper 7, and the other end of the rotating shaft 24 is rotatably connected to the inner side wall of the concave frame 6. The sub-gear 25 is fixedly sleeved around the rotating shaft 24, and the sub-gear 25 meshes with the main gear 23. A storage battery 26 is installed inside the stamper 7.

[0032] When it is necessary to replace the stamping die 8, on the premise that the PLC controller 22 is set to be signal-connected to the braking motor 21, and the braking motor 21 is controlled by the PLC controller 22 to work. The braking motor 21 drives the main gear 23, the auxiliary gear 25, the rotating shaft 24, the stamping plate 7 and the stamping die 8 to rotate until the corresponding stamping die 8 is located at the lowermost end of the stamping plate 7. Then the PLC controller 22 controls the braking motor 21 to stop working. Therefore, it is convenient to replace the stamping die 8 of the corresponding specification to perform stamping processing on the paper box.

[0033] As Figure 2 , 3 , as shown in FIG. 6, in this embodiment, circular mounting blocks 15 are fixedly arranged inside the stamping dies 8. A plurality of circular mounting grooves 14 are formed in the periphery of the stamping plate 7. The plurality of circular mounting blocks 15 correspond to the plurality of circular mounting grooves 14 one by one, and the circular mounting blocks 15 are butted inside the circular mounting grooves 14. Shrinkage grooves 19 are formed on both sides of the inner wall of the circular mounting groove 14. Spring return rods 20 are fixedly arranged inside the shrinkage grooves 19. A clamping block 18 is connected to the end of the spring return rod 20. Claw slots 17 matching the clamping blocks 18 are formed on both sides of the circular mounting block 15. The clamping blocks 18 are clamped inside the claw slots 17. The clamping blocks 18 are in the shape of a quarter circle.

[0034] When it is necessary to disassemble and replace the stamping die 8 on the stamping plate 7, turn the stamping die 8 to drive the circular mounting block 15 to rotate inside the circular mounting groove 14. Since the clamping block 18 is in the shape of a quarter semi-circle, the circular mounting block 15 will push the clamping block 18 into the shrinkage groove 19 along the arc surface of the clamping block 18. The clamping block 18 will compress the spring return rod 20 until the clamping block 18 moves out of the claw slot 17. At this time, the circular mounting block 15 can be removed from the circular mounting groove 14. Therefore, the corresponding stamping die 8 can be conveniently disassembled from the stamping plate 7. Then, a new stamping die 8 of other specifications is installed on the stamping plate 7. Therefore, the circular mounting block 15 is inserted into the circular mounting groove 14, and the stamping die 8 and the circular mounting block 15 are rotated. During this process, the circular mounting block 15 pushes the clamping block 18 into the shrinkage groove 19 along the arc surface of the clamping block 18. The clamping block 18 will compress the spring return rod 20 until the clamping block 18 aligns with the claw slot 17. The resilience of the spring return rod 20 will drive the clamping block 18 to be clamped into the claw slot 17. Therefore, the stamping die 8 can be conveniently installed on the stamping plate 7. In summary, the entire disassembly and assembly process of the stamping die 8 does not require disassembly and assembly by bolts, and the disassembly, assembly and replacement process of the stamping die 8 is very convenient.
