Description

Technical Field

[0001] This utility model relates to the field of die-cutting machine technology, and in particular to a quick die-changing mechanism for a double-sided adhesive die-cutting machine for automobiles. Background Technology

[0002] Die-cutting machines are mainly used in the paper packaging and decoration industry for die-cutting, creasing, and cold embossing of trademarks, boxes, greeting cards, etc., and are important equipment for post-printing packaging processing. Die-cutting machines are mainly divided into three types according to the embossing method: rotary-to-rotary, rotary-to-flat, and flat-to-flat. They can also be divided into vertical and horizontal types according to the mold placement. During operation, die-cutting machines require changing different molds according to the material and shape to be die-cut. For example, patent (CN217943597U) describes an automatic mold switching device for a cutting machine. This device uses an automatic switching valve 410 to transport the die 1 to below the cutting head 520, and the cutting head 520 and clamping block 530 automatically clamp the die, completing the die change. However, this device occupies a large space on its left side, and the changing process is relatively complex and inconvenient to operate. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quick mold changing mechanism for a double-sided adhesive die-cutting machine for automobiles.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design a quick mold changing mechanism for a double-sided adhesive die-cutting machine for automobiles, including a base, a support vertically mounted on the upper surface of the base, a crank rotatably mounted on the support, a first motor mounted on the support and connected to the crank, a connecting rod rotatably connected to the crank, and a template rotatably connected to the bottom of the connecting rod via a hinge, a die-cutting seat mounted on the upper surface of the base, an mounting cylinder rotatably mounted in the middle of the die-cutting seat, and a mold mounted on the outer wall of the mounting cylinder.

[0006] Preferably, the cross-section of the mounting cylinder is hexagonal, and the hexagonal surface of the mounting cylinder is provided with a mounting groove, and the mold is snapped into the inner cavity of the mounting groove.

[0007] Preferably, the sidewall of the mold is integrally formed with a locking block, and the outer wall of the mounting cylinder has a first locking groove, into which the locking block is engaged and fastened with screws.

[0008] Preferably, a second slot is formed on the upper end face of the die-cutting seat, and a pad is rotatably connected in the second slot via a second rotating shaft.

[0009] Preferably, the side of the pad has a wedge-shaped cut surface, which fits against the side wall of the mounting cylinder.

[0010] Preferably, a motor mount is provided on the upper surface of the base, a second motor is mounted on the motor mount, a first rotating shaft is coaxially provided in the middle of the mounting cylinder, and the second motor is connected to the first rotating shaft.

[0011] Preferably, a positioning rod is vertically arranged on the upper end face of the die-cutting seat, and the positioning rod passes through a positioning hole opened on the outer wall of the upper template.

[0012] The present invention proposes a quick mold changing mechanism for a double-sided adhesive die-cutting machine for automobiles. The advantages are as follows: by setting a hexagonal mounting cylinder, the mold is installed on the six surfaces of the hexagon. When changing molds, simply rotate the first rotating shaft to align the different molds with the upper template. The first motor drives the upper template to move down, and the upper template closes with the mold to perform die-cutting on the double-sided adhesive that has passed through the upper template. The entire mold changing process does not require manual intervention, is simple and easy to operate, and is safer and more reliable. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1A quick mold changing mechanism for a double-sided adhesive die-cutting machine for automobiles includes a base 11, a support 1 vertically mounted on the upper surface of the base 11, a crank 20 rotatably mounted on the support 1, a first motor 2 mounted on the support 1, the first motor 2 connected to the crank 20, a connecting rod 3 rotatably connected to the crank 20, and a template 5 rotatably connected to the bottom of the connecting rod 3 via a hinge 4. A die-cutting seat 10 is mounted on the upper surface of the base 11, and an mounting cylinder 19 is rotatably mounted in the middle of the die-cutting seat 10. A mold 16 is mounted on the outer wall of the mounting cylinder 19, and different molds 16 are mounted on each surface of the mounting cylinder 19. When changing molds, the mounting cylinder 19 can be rotated in sequence, which is simple and easy to operate.

[0021] Reference Figure 5 The mounting cylinder 19 has a hexagonal cross-section, and a mounting groove 18 is provided on the hexagonal surface of the mounting cylinder 19. The mold 16 is snapped into the inner cavity of the mounting groove 18. The side wall of the mold 16 is integrally formed with a locking block 17. The outer wall of the mounting cylinder 19 has a first locking groove 15. The locking block 17 is snapped into the first locking groove 15 and fastened with screws. The mold 16 can be disassembled and replaced by fastening with screws so as to install more different types of molds 16.

[0022] Reference Figure 4 , 5 A second slot 21 is provided on the upper end face of the die-cutting base 10. The pad 12 is rotatably connected to the second slot 21 through the second rotating shaft 13. The side of the pad 12 is provided with a wedge-shaped cut surface 14. The wedge-shaped cut surface 14 fits against the side wall of the mounting cylinder 19. When the double-sided adhesive passes between the upper template 5 and the mold 16, the pad 12 acts as a pad for the double-sided adhesive. When the mounting cylinder 19 rotates, it drives the pad 12 to rotate along the second rotating shaft 13. When the rotation reaches the level position, the two pads 12 fit against the two sides of the mounting cylinder 19, reducing the gap between the pad 12 and the mounting cylinder 19, and avoiding excessive gap from adversely affecting the die-cutting of the double-sided adhesive.

[0023] Reference Figure 3 A motor base 7 is provided on the upper end face of the base 11, and a second motor 6 is installed on the motor base 7. A first rotating shaft 9 is coaxially provided in the middle of the mounting cylinder 19. The second motor 6 is connected to the first rotating shaft 9. The mounting cylinder 19 is rotated by the second motor 6 without manual operation, which is safer and more reliable. At the same time, the second motor 6 is a stepper motor and is equipped with a brake device at its tail to prevent self-rotation.

[0024] Reference Figure 3 A positioning rod 8 is vertically set on the upper end face of the die-cutting base 10. The positioning rod 8 passes through the positioning hole opened on the outer wall of the upper template 5. The positioning rod 8 prevents the upper template 5 from moving to the side, ensuring that the upper template 5 can move up and down more stably. During the up and down movement of the upper template 5, the double-sided adhesive and the mold 16 are die-cut.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
