Description

Technical Field

[0001] This utility model relates to the field of die-cutting machine technology, specifically a bonding device for a die-cutting machine. Background Technology

[0002] A die-cutting machine is a device used to cut various materials into pre-designed shapes. It is widely used in many industries such as packaging printing, label making, and electronics manufacturing. When making labels, a bonding device is usually installed on the die-cutting machine. The bonding device can first bond the label paper with the release paper, and then transfer the bonded label to the die-cutting machine for die cutting. During the die-cutting process, excess waste (such as scraps) can be removed to ensure that the edges of the label are neat and clean.

[0003] Commonly used laminating devices mainly consist of laminating rollers. During label transport, the laminating rollers roll and bond the release paper and the label paper together. However, laminating rollers can generally only laminate labels that have not yet been die-cut, and cannot re-laminate labels that have been die-cut. This is because the die-cut edges of the label are prone to wrinkles or unevenness during the die-cutting process. Re-rolling can smooth out these wrinkles and enhance the adhesion between the label paper and the release paper. Furthermore, traditional laminating rollers cannot improve the lamination effect of the label by repeatedly rolling the label. Utility Model Content

[0004] The purpose of this invention is to provide a bonding device for a die-cutting machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A bonding device for a die-cutting machine, comprising:

[0007] A carrier plate, one end of which is rotatably connected to a bonding roller, which can initially roll and bond the release paper and label paper on the label;

[0008] Multiple bonding components are arranged on the top of the carrier plate. Each bonding component includes a crossbeam, a positioning post is rotatably inserted into the middle of the crossbeam, and movable posts are slidably connected to both ends of the crossbeam. A connecting seat is fixed at the bottom of the movable post, and a second bonding roller is rotatably connected between the two connecting seats. The second bonding roller can roll on the label.

[0009] The transmission assembly is arranged inside the die-cutting machine and can drive the bonding assembly to operate by moving the die-cutting base up and down. The transmission assembly includes a gear that is rotatably connected to the die-cutting machine. The outer side of the gear is engaged with a first transmission column and two second transmission columns. The first transmission column is fixedly installed to the die-cutting base, and the second transmission columns can drive the crossbeam to move.

[0010] Furthermore, each of the two transmission columns is fixed with a slide rail, and the inner side of the die-cutting machine has two slide grooves that are slidably connected to the corresponding slide rails.

[0011] Furthermore, racks are fixed to the outer sides of both transmission column one and transmission column two, and the racks mesh with gears for transmission.

[0012] Furthermore, one end of the transmission column 2 is fixed with a connecting rod 1, and the connecting rod 1 is fixedly connected to the positioning column.

[0013] Furthermore, a nut is screwed onto the outer side of the positioning post, and a limit block is fixed to the bottom of the positioning post.

[0014] Furthermore, a compression spring is arranged between the end of the crossbeam and the connecting seat, and the compression spring is sleeved on the outside of the movable column.

[0015] Furthermore, a detachable and fixed connecting rod two is installed on the outer side of the first connecting rod, and a fitting component is installed and fixed at one end of the second connecting rod.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. By arranging an bonding component at both ends of the die-cutting base, the bonding rollers on the bonding components roll on the surface of the label. When the die-cutting machine drives the die-cutting base to move down for die-cutting, the die-cutting base moves down synchronously with the transmission column one. The moving transmission column one drives the gear to rotate. The rotating gear drives the two transmission columns two to slide along the die-cutting machine in opposite directions. This causes the transmission columns two to drive the bonding rollers two on the two bonding components to roll the label on the label in the direction away from the die-cutting base through the crossbeam. When the die-cutting base finishes and moves up, the transmission column one will drive the gear to rotate in the opposite direction. The gear will drive the transmission column two to move back towards the die-cutting base with the bonding rollers two. This enables the bonding rollers two at different positions to reciprocate and roll the label before and after die-cutting during the die-cutting process.

[0018] Reciprocating rolling before label die-cutting helps improve the tightness of the adhesion between the label paper and the release paper. Reciprocating rolling after label die-cutting helps smooth out wrinkles at the die-cut edges and further enhances the adhesion between the label paper and the release paper.

[0019] 2. By fixing connecting rod 2 to the end of connecting rod 1 and installing and fixing a bonding component at the bottom of connecting rod 2, the transmission column 2 can simultaneously drive the bonding components on connecting rod 1 and connecting rod 2 to perform bonding operations on the label. The two bonding rollers 2 on the two adjacent bonding components can roll the label over a long distance, which helps to expand the area of ​​the bonding components rolling the label.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1, please refer to Figure 1 - Figure 5In this embodiment of the present invention, a bonding device for a die-cutting machine includes a carrier plate 100, one end of which is rotatably connected to a bonding roller 110. Multiple bonding components 200 are arranged on the top of the carrier plate 100. The bonding components 200 can roll and bond the release paper and label paper before and after die-cutting. Each bonding component 200 includes a crossbeam 210, with a positioning post 220 movably inserted into the middle of the crossbeam 210. Both ends of the crossbeam 210 are slidably connected to movable posts 230. A connecting seat 240 is fixed at the bottom of 230. A bonding roller 250 is rotatably connected between the two connecting seats 240. A transmission assembly 300 is provided on the inner side of the die-cutting machine. The transmission assembly 300 includes a gear 310 rotatably connected to the die-cutting machine. A transmission column 320 and two transmission columns 330 are meshed on the outer side of the gear 310. The transmission column 320 is installed and fixed to the die-cutting seat 510. The transmission columns 330 can drive the crossbeam 210 to move so that the bonding assembly 200 can operate.

[0028] Specifically, by arranging a bonding roller 250 at each end of the die-cutting base 510, when the die-cutting base 510 moves up and down to perform the die-cutting operation, the transmission column 320 will cause the gear 310 to rotate in both directions. The rotation of the gear 310 in both directions will cause the two transmission columns 330 to move in opposite directions first, and then move in the direction of mutual approach. This allows the transmission column 330 to carry the two bonding rollers 250 to roll the label back and forth on the label before and after die-cutting, which improves the adhesion of the label and helps to flatten the uneven areas at the die-cutting position.

[0029] like Figure 1 and Figure 2 As shown, in this embodiment, a slide rail 350 is fixed on one side of the transmission column 330, and two slide grooves 520 are opened on the inner side of the die-cutting machine, which are respectively slidably connected to the slide rails 350 at the corresponding positions, so that the transmission column 330 can slide stably linearly back and forth on the die-cutting machine.

[0030] like Figure 3 As shown, in this embodiment, both the outer sides of the first transmission column 320 and the second transmission column 330 are fixed with racks. The racks mesh with the gear 310 for transmission. When the die-cutting seat 510 moves downward with the first transmission column 320 for die-cutting, the rack on the first transmission column 320 drives the gear 310 to rotate clockwise. The rotating gear 310 then moves the rack on the second transmission column 330 in a direction away from each other, thereby causing the two second transmission columns 330 to move in a direction away from each other, and then causing the second transmission column 330 to roll the second bonding roller 250 on the bonding assembly 200 onto the label.

[0031] In this embodiment, when the die-cutting seat 510 completes the die-cutting and moves upward, the first transmission column 320 will drive the gear 310 to rotate in the opposite direction. The gear 310 rotating in the opposite direction will drive the two second transmission columns 330 to move in a direction closer to each other, so that the second transmission column 330 carries the second bonding roller 250 on the two bonding components 200 to roll the label in the opposite direction.

[0032] like Figure 1 As shown, in this embodiment, two support seats 120, both rotatably connected to the bonding roller 110, are fixed at one end of the carrier plate 100. In the initial state, the label paper and release paper are transported in the same direction between the bonding roller 110 and the carrier plate 100, so as to perform preliminary rolling bonding of the label when transporting the label. The external winding roller for winding the label and the release roller for releasing the label are existing technologies and will not be described in detail here.

[0033] like Figure 3 and Figure 4 As shown, in this embodiment, a connecting rod 340 is fixed to one end of the transmission column 330, and the connecting rod 340 is fixedly connected to the positioning column 220. An L-shaped rod 332 is fixed between one transmission column 330 and the connecting rod 340, so that the two transmission columns 330 can be driven by the gear 310 at the same time without moving or interfering with each other.

[0034] like Figure 3 and Figure 5 As shown, in this embodiment, a nut 221 is screwed onto the outer side of the positioning post 220, and a limit block is fixed at the bottom of the positioning post 220. When the fitting component 200 is installed on the connecting rod 340, the nut 221 can be screwed and rotated to position and fix the crossbeam 210 at the bottom of the positioning post 220, preventing the crossbeam 210 from moving.

[0035] In this embodiment, specific reference is made. Figure 5 When the width of the label is small, the crossbeam 210 can be rotated and tilted in advance so that the tilted bonding roller 250 can fully contact the label, thereby improving the rolling bonding effect of the bonding roller 250.

[0036] like Figure 3 As shown, in this embodiment, a compression spring 241 is arranged between the end of the crossbeam 210 and the connecting seat 240. The compression spring 241 is sleeved on the outside of the movable column 230. The elastic force of the compression spring 241 can drive the connecting seat 240 to have a tendency to move towards the carrier plate 100, thereby making the connecting seat 240 have a tendency to move towards the carrier plate 100 with the second bonding roller 250, which helps the second bonding roller 250 to compact the rolled label.

[0037] In this embodiment, a limiting ring is fixedly fitted to the top of the movable column 230, which can prevent the movable column 230 from detaching from the crossbeam 210.

[0038] like Figure 4 As shown, in this embodiment, a detachable and fixed connecting rod 400 is installed on the outer side of the connecting rod 340. An adhesive component 200 is installed and fixed at one end of the connecting rod 400. By installing the connecting rod 400, multiple adhesive components 200 can be installed on one connecting rod 340, so that the transmission column 330 can simultaneously carry multiple adhesive rollers 250 to roll over the label over a long distance, so that the label die-cut by the die-cutting seat 510 is a label that has been rolled and adhered.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
