Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary devices for equipment for making paper boxes, cardboard boxes, envelopes or paper bags classified as IPC B31B, and particularly relates to a structural innovation and improvement technology for a mold adapter kit device used in conjunction with a gift box bubble pressing machine. Background Art

[0002] Currently, in the packaging industry, when making packaging boxes, one layer of packaging box is first coated with glue, and then another layer of packaging box is pasted on the glued box. However, after the two layers of packaging boxes are pasted together, a large number of bubbles will appear at the pasting point, resulting in a loose paste. However, by placing the pasted packaging boxes on the mold of a bubble pressing machine and pressing them tightly with a pressing plate, the bubbles can be expelled from the pasting point where the two layers of packaging boxes are pasted together. The bubble pressing machine is one of the important and indispensable equipment in the packaging industry. Its emergence has greatly improved the production efficiency and quality of paper box packaging.

[0003] A bubble press is a new type of flattening and correction device specifically designed to address issues such as bubbles, bulges, wrinkles, and deformation on the laminating surface of post-molding cartons. It is primarily used in the carton packaging industry, particularly for flattening high-end, premium cartons. This device utilizes heat and pressure to flatten the carton surface, eliminating bubbles and wrinkles and improving the aesthetics and quality of the cartons.

[0004] The use of bubble presses can significantly improve carton production efficiency and product quality, reduce defective product rates, and bring significant benefits and convenience to the packaging industry. Furthermore, with the continuous advancement of technology, the performance and functionality of bubble presses are constantly improving and refining, providing strong technical support for the development of the packaging industry. Furthermore, depending on production needs, bubble presses may also include glue application, dispensing, and drying functions to meet more complex production process requirements. These features make bubble presses more widely and diversely used in the packaging industry.

[0005] However, in some existing bubble pressing machines, the molds and pressing plates are mostly welded on the bubble pressing machines. After long-term work, they will be worn out and it is not convenient to disassemble and repair them, which affects the processing quality. When different packaging boxes need to be processed, different molds need to be selected for installation. The mold replacement procedure is cumbersome and the disassembly and assembly are troublesome, which affects the processing progress.

[0006] The relevant technical solutions are less disclosed. Patent application No. 202122046768.0 discloses a bubble pressing machine that is easy to replace the mold, which belongs to the field of packaging box processing technology, including: a bubble pressing machine frame; a pad is provided on one side of the bubble pressing machine frame and a cylinder is provided on the top, and a piston rod is provided at the power output end of the cylinder, one end of the piston rod passes through the bubble pressing machine frame and is fixedly connected to the pressure plate seat, the top of the pressure plate seat is penetrated and connected with four groups of bolts, and the bottom of the pressure plate seat is detachably connected to the pressure plate through the four groups of bolts, and the outer wall of the bubble pressing machine frame is provided with a motor box, a motor is fixedly installed inside the motor box, and the motor power output end is fixedly connected to a linkage block, and the outer wall around the linkage block is fixedly connected with four groups of mounting seats for mounting the mold, and the mounting seat is a concave structure and a clamping rod for fixing the mold is provided in the groove.

[0007] In particular, many commonly used bubble pressing machines can only produce regular gift boxes that can be processed normally. The molds for small-sized gift box products do not support replacement. Similarly, there is a difficult choice in the value assessment of economy and operational complexity for replacing molds for small-batch products that are temporarily processed.

[0015] By adopting the above technical solution, in particular, threads are provided on the outer surface of the upper and middle sections of the suspension rod.

[0016] Furthermore, the upper middle section of the suspension rod has a C-shaped hook structure.

[0017] Especially, an adjusting bolt is installed on the bottom end of the embedded suspension rod in the side groove.

[0046] In the embodiment of the present invention, a control console 4 is installed at the rear side of the bottom of the frame 1, a workbench 3 is installed at the front side of the bottom of the frame 1, and a top platform 2 is extended forward from the top of the frame 1; a top cylinder 5 is installed on the upper side of the top platform 2, and an upper piston 6 is extended downward from the top cylinder 5 and passes through the top platform 2 and is connected to a pressure plate 7; further, an upper mold 8 is installed on the bottom surface of the pressure plate 7, and a lower mold 9 is installed on the top surface of the workbench 3; a side pusher 22 is installed next to the workbench 3; according to the existing technical practice, the upper mold 8 is usually glued to the bottom surface of the pressure plate 7, and the lower mold 9 is also glued to the upper side of the workbench 3; while keeping the upper mold 8 and the lower mold 9 in their original installation state, the process of installing and using a new upper mold 10 and a new lower mold 21 includes:

[0047] 1) First, glue and install the new upper mold 10 in the middle of the bottom surface of the upper replacement seat 11; then, open a connection hole corresponding to the upper replacement seat 11 on the pressure plate 7, pad the upper side of the upper replacement seat 11 with an upper vibration-damping pad 12, covering the bottom surface of the upper original mold 8, and extend the suspension rods 13 extending upward from the four corners of the upper replacement seat 11 upward through the corresponding connection holes on the pressure plate 7 and tighten them at the upper middle section of the suspension rods 13;

[0048] 2) First, glue and install the new lower mold 21 in the middle of the top surface of the lower replacement seat 17; then, cover the top surface of the lower original mold 9 with the lower shock-absorbing pad 16. Then, press the lower replacement seat 17 onto the upper side of the lower shock-absorbing pad 16. Finally, install the fastening bolts 19 at the corners of the top surface of the lower replacement seat 17, thereby fixing the lower replacement seat 17 to the workbench 3;

[0049] 3) Debug the precise fit of the new upper die 10, the new lower die 21, and the side pusher 22. After alignment, fold the corner clip 18 at the corner of the top surface of the lower replacement seat 17 and tighten the fastening bolt 19 to ensure that the corner clip 18 stably and firmly positions the new lower die 21.

[0050] 4) During operation, the sheet material for the bubble packaging box is loaded and covered on the top surface of the new lower mold 21, and the top cylinder 5 drives the pressure plate 7 to press down, and the new upper mold 10 and the new lower mold 21 are closed. At the same time, multiple sets of side pushers 22 push the extrusion edge centripetally, and the packaging box sheet is bubbled and formed. After the pressure plate 7 is lifted, the side pushers 22 also complete the retreat. Finally, the demoulding airflow is sprayed from the replacement through hole 20 to lift the formed bubble packaging box. At this time, a side pusher 22 can also be set to move forward quickly to push the formed bubble packaging box out of the bubble station.

[0051] In this embodiment of the utility model, when producing small gift boxes with limited space, the large mold is mainly used to provide stable pressure and movement trajectory, while the small mold is responsible for direct contact with the small gift box to ensure precise molding and bubble pressing effect. Selecting the right bubble pressing machine and skilled operators are still the key factors to ensure production quality and efficiency.

[0052] The implementation principle of this embodiment is: some settings and adjustments are performed before operation to ensure that the coordinated movement between the large mold and the small mold can meet the production requirements of the small gift box.

[0053] The above embodiments are merely examples to more clearly illustrate the technical solution, and are not intended to limit the implementation of the present invention.

[0054] Although the above embodiments describe the implementation of the present invention in conjunction with the drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations shall fall within the scope defined by the appended claims.
