[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1

[0028] In order to solve the problem that the position of the packaging box shifts during the indentation process, resulting in deviation in the position after indentation, please refer to Figures 1-3 , this embodiment provides an indentation device for packaging box production, which can clamp and fix the packaging box to prevent it from moving during the indentation process, thereby ensuring that the position of the indentation is accurate. The device includes a bracket 1 located in the processing area, and the bracket 1 serves as a carrier for carrying the structure set thereon. The bracket 1 is provided with a clamping component 2 for fixing the packaging box, and the bracket 1 is provided with an indentation component 3 for indenting the packaging box. When the packaging box is indented, it is placed on the clamping component 2, clamped and fixed by the clamping component 2, and then indented under the action of the indentation component 3, so that the packaging box will not move during the indentation process, thereby ensuring that the position of the indentation is accurate. Make sure that each indentation can fall accurately on the predetermined position.

[0029] During the indentation process, the packaging box may be displaced due to external forces, such as the pressure of the indentation block 33, the vibration of the equipment, etc. Once displaced, the position of the indentation will deviate, resulting in inaccurate folding of the packaging box, affecting the overall appearance and structure. Therefore, it is necessary to restrict its position to prevent its position from shifting. The clamping assembly 2 includes a concave mounting frame 21 rotatably mounted on the bracket 1, and the mounting frame 21 serves as a carrier. A placement table 22 is fixedly connected to the mounting frame 21, and the placement table 22 is used to place the processed packaging box. A bidirectional screw 23 is rotatably mounted on the mounting frame 21 and passes through the placement table 22. The bidirectional screw 23 limits the movement path of the splint 27 and transmits it. Slide grooves 24 are provided at both ends of the placement table 22. The slide grooves 24 are used to limit the connecting plate 25 so that it does not slide with the bidirectional screw 23. A concave connecting plate 25, symmetrically arranged and threaded onto the bidirectional screw 23, is slidably connected within the chute 24. The connecting plate 25 is slightly shorter than the placement platform 22, ensuring that the packaging boxes on the placement platform 22 can be adjusted and clamped. A mounting block 26 is fixedly connected to the end of the connecting plate 25. A T-shaped clamping plate 27 is slidably connected within the mounting block 26. A spring 28 is fixedly connected between the clamping plate 27 and the mounting block 26 to limit the movement of the clamping plate 27. A first motor 29 is fixedly mounted on the mounting frame 21 to drive the bidirectional screw 23. When the packaging box is indented, the first motor 29 is started, and the bidirectional screw 23 is rotated by the motor, and the connecting plate 25 drives the clamping plate 27 to slide along the surface of the bidirectional screw 23 to approach or move away from the packaging box on the placement table 22 under the restriction of the slide 24. When the clamping plate 27 is adjusted to the appropriate position, the clamping plate 27 is lifted, and then the packaging box is placed on the placement table 22. The clamping plate 27 can then be loosened so that the packaging box is clamped and fixed under its gravity and the elastic force of the spring 28, so that the packaging box will not move during the indentation process, thereby ensuring that the position of the indentation is accurate. Each indentation can be accurately placed at the predetermined position, and the subsequent folding and assembly process of the packaging box is smoother, and the various parts can be perfectly spliced together, thereby improving the appearance and tightness of the packaging box, reducing the defective rate of the packaging box production, and improving production quality.

[0030] Considering that the packaging box needs to be indented to ensure the subsequent folding of the packaging box, and the indentation specifications need to be adjusted in the face of different packaging box specifications to ensure that it can be processed normally, refer to Figures 1-3, the indentation assembly 3 includes a mounting table 31 fixedly installed on the bracket 1, and the mounting table 31 is used to support the electric push rod 35. A mounting plate 32 is slidably connected in the mounting table 31, and the mounting plate 32 is used to connect the indentation block 33 and the electric push rod 35. The indentation block 33 is detachably installed on the mounting plate 32, and the indentation block 33 is used to perform indentation processing on the packaging box on the placement table 22. The cross-section of the indentation block 33 is trapezoidal, and the end surface of the indentation block 33 is smooth, reducing the contact with the surface of the packaging box and reducing the damage caused by friction to it. A bolt 34 is threadedly connected between the mounting plate 32 and the indentation block 33, and the bolt 34 is used to connect the mounting plate 32 and the indentation block 33. An electric push rod 35 for driving the mounting plate 32 to slide in the vertical direction is fixedly installed on the mounting table 31. When processing the packaging box, first install the indentation block 33 that meets the indentation specifications on the mounting plate 32 through the bolt 34, and then start the electric push rod 35. Driven by it, the mounting plate 32 drives the indentation block 33 to slide vertically close to or away from the packaging box on the placement table 22 to perform indentation processing on it. Furthermore, when performing different indentation processing on the packaging box, the indentation specifications can be quickly adjusted and replaced, enabling different specifications of indentation processing on the packaging box, reducing downtime, enabling continuous production, avoiding production delays and cost increases caused by too long adjustment time, improving the utilization rate of the equipment and the overall production efficiency. Reducing material waste caused by inaccurate indentation. Meeting the personalized needs of customers for the packaging box, increasing the added value of the product, and enhancing customer satisfaction and loyalty.

[0031] Considering that the indentation of the packaging box needs to be processed in more than one direction, at this time, it is necessary for workers to continuously disassemble and install the packaging box. During the continuous disassembly and assembly process, it is very easy to cause inaccurate indentation positions due to position adjustment, and damage it during disassembly and assembly, affecting the subsequent use of the packaging box. Therefore, it is necessary to reduce the number of disassembly and assembly times. Refer to Figures 1-3, there is a gap between the clamping plate 27 and the placing table 22, and the height of the gap is less than the thickness of the processed packaging box, ensuring that friction is caused between the clamping plate 27 and the placing table 22 during position adjustment, which affects the processing of the packaging box. The length of the mounting frame 21 is much greater than the length of the placing table 22, and the length of the mounting table 31 is greater than that of the mounting frame 21, ensuring that the mounting frame 21 will not collide with the mounting table 31 during position adjustment and ensuring that the position can be adjusted normally. The height of the indentation block 33 when not processing the packaging box is greater than the height of the mounting block 26, ensuring that the indentation block 33 will not collide with the mounting block 26 during the position adjustment of the mounting frame 21. A second motor 4 for driving the rotation of the mounting frame 21 is fixedly installed on the bracket 1. When performing indentation processing on the packaging box and when position adjustment is required, the electric push rod 35 drives the indentation block 33 back to the original position, and then the second motor 4 is started. Under its drive, the mounting frame 21 can rotate, thereby adjusting the position of the packaging box fixed on the placing table 22, enabling it to be quickly adjusted at different indentation processing positions, reducing frequent manual disassembly, and thus reducing the position deviation and damage caused during disassembly and position adjustment, reducing the operation difficulty and labor intensity, and improving the work efficiency and production quality.

[0032] Embodiment 2

[0033] On the basis of Embodiment 1, considering that the clamping plate 27 is likely to damage the surface of the packaging box on the placing table 22 under the pressure of the indentation block 33 during clamping, affecting the integrity and aesthetics of the packaging box, it is necessary to reduce the damage to it during indentation processing. Refer to Figures 1-3 , the length of the clamping plate 27 is greater than the width of the placing table 22, ensuring that the packaging box on the placing table 22 can be clamped. A plurality of rubber pads 271 are fixedly connected to the end of the clamping plate 27, and the height of the rubber pads 271 exceeds the surface height of the clamping plate 27. When clamping the packaging box, the rubber pads 271 can be closely attached to the surface of the packaging box under the action of the clamping plate 27 to clamp it. When processing it under the action of the indentation block 33, the material characteristics of the rubber pads 271 can reduce the damage to it, and can increase the clamping effect on the surface of the packaging box, improve the effect that the packaging box will not deviate during processing, reduce the impact on the packaging box during processing, improve its aesthetics and integrity after processing, reduce the defective rate during production, and reduce the production cost.
