Abstract
Description
Technical Field
[0001] This utility model relates to the field of die-cutting machine technology, specifically to an auxiliary dust removal structure for a transparent PET double-sided adhesive die-cutting machine. Background Technology
[0002] Die-cutting machines, also known as die-cutting machines, cutting machines, or CNC punching machines, are mainly used for die-cutting (full cut, half cut), creasing, hot stamping, laminating, and automatic waste removal of various non-metallic materials, self-adhesive labels, EVA, double-sided tape, electronic products, and mobile phone pads. They utilize steel blades, metal molds, and steel wire (or templates carved from steel plates) to apply pressure through an imprinting plate, cutting printed materials or cardboard into specific shapes. They are essential equipment for post-printing packaging processing. Transparent PET double-sided tape is cut using a die-cutting machine.
[0003] A utility model patent with patent authorization announcement number CN108996296B discloses a die-cutting machine, including an inner support plate, an outer support plate, a guide roller located between the inner support plate and the outer support plate, and a clamping device installed above the guide roller. The die-cutting machine also has a guiding device installed on one side of the guide roller. The guiding device has a guiding strip located near the guide roller. The die-cutting machine provided by this invention has a guiding device, and the set screw on the guiding device ensures that the angle of the guiding device remains consistent. Furthermore, the guiding device can strengthen the tension of the material on the guide roller and prevent material deviation, which would ultimately lead to a decrease in the neatness of the cross-section when the die-cutting machine is rewound.
[0004] Currently, when cutting transparent PET double-sided tape, multiple limiting devices are needed to press down and limit the cutting edge on the left and right. However, the limiting devices on the left and right sides often need to be adjusted separately, which increases the complexity of the adjustment. Moreover, the stability of manual adjustment of the limiting is not good. At the same time, after the cutting edge is cut, the glue adhering to the inside of the double-sided tape mold leaks out, which makes it easy to stick to dust when it comes into contact with dust, affecting the cleaning of the cutting edge. Utility Model Content
[0005] The purpose of this invention is to provide an auxiliary dust removal structure for a transparent PET double-sided tape die-cutting machine, which solves the problems of limiting the position of the transparent PET double-sided tape and preventing dust from entering the cut edge of the transparent PET double-sided tape.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary dust removal structure for a transparent PET double-sided tape die-cutting machine, comprising a worktable, a plurality of support legs fixedly connected to the lower end of the worktable, a hidden groove opened on the worktable, double-sided tape slidably connected to the upper end of the worktable, the double-sided tape slidingly passing through the upper end of the hidden groove, a limit mechanism provided on the worktable, and a dust removal mechanism provided at the upper end of the worktable.
[0007] Preferably, the limiting mechanism includes a lifting block, the lower end of the worktable is fixedly connected to the lifting block, the lower end of the lifting block is fixedly connected to a telescopic rod, the lower end of the telescopic rod is fixedly connected to a hanging plate, and the telescopic rod is connected to the lower end of the worktable.
[0008] Preferably, connecting blocks are fixedly connected to the left and right sides of the hanging plate, and a sliding rod is fixedly connected to the upper end of the connecting block. The sliding rod slides through the worktable, and a front pressure plate and a rear pressure plate are fixedly connected to the upper end of the sliding rod.
[0009] Preferably, the front pressure plate and the rear pressure plate are respectively connected to the upper end of the workbench, and the lower ends of the front pressure plate and the rear pressure plate are respectively fixedly connected with protective pads. The front pressure plate and the rear pressure plate press down on the protective pads to fit tightly against the upper end of the double-sided tape.
[0010] Preferably, the dust removal mechanism includes a support frame, the upper end of the workbench is fixedly connected to the support frame, the upper end of the support frame is fixedly connected to a dust suction hood, and the upper end of the dust suction hood is fixedly connected to a flow guide hood.
[0011] Preferably, a vacuum cleaner is fixedly connected to the upper end of the flow guide, and a suction pipe is fixedly connected to the lower end of the vacuum cleaner, with the suction pipe passing through the upper end of the flow guide.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model connects a hanging plate to a telescopic rod, a connecting block to the hanging plate, and a sliding rod to the connecting block. The upper end of the sliding rod is fixedly connected to the front pressure plate and the rear pressure plate, respectively. Thus, the front pressure plate and the rear pressure plate can be automatically raised and lowered by the telescopic rod. The telescopic rod can also drive the front pressure plate and the rear pressure plate to squeeze the double-sided tape at different positions. This not only achieves the effect of limiting multiple double-sided tapes at once, but also achieves the effect of automatic adjustment.
[0014] 2. This utility model allows dust to be absorbed into the dust collection hood when the vacuum cleaner is working. Then, the dust collection hood and the guide hood move the dust to the suction pipe, and then the dust collection pipe moves the dust to the vacuum cleaner. The dust collection hood increases the absorption area, and the guide hood guides and facilitates the movement of dust, thus increasing the dust absorption effect. Attached Figure Description

The worktable 1 is provided with a limit mechanism 5. A dust removal mechanism 6 is provided at the upper end of the worktable 1. This technical solution improves upon the problems mentioned in the background art. Other technical problems of this technical solution are existing technologies and will not be described in detail here.
[0022] Please see Figure 1 , Figure 2 , Figure 3The limiting mechanism 5 includes a lifting block 51. The lifting block 51 is fixedly connected to the lower end of the worktable 1. A telescopic rod 52 is fixedly connected to the lower end of the lifting block 51. The telescopic rod 52 is model YNT-03. The plug of the telescopic rod 52 is connected to an external power supply, which is existing technology. A hanging plate 53 is fixedly connected to the lower end of the telescopic rod 52. The telescopic rod 52 is connected to the lower end of the worktable 1. Connecting blocks 54 are fixedly connected to the left and right sides of the hanging plate 53, respectively. A sliding rod 55 is fixedly connected to the upper end of the connecting block 54. 5. The slide rod 55 slides through the workbench 1. The upper end of the slide rod 55 is fixedly connected to the front pressure plate 56 and the rear pressure plate 57 respectively. The front pressure plate 56 and the rear pressure plate 57 are respectively connected to the upper end of the workbench 1. The lower end of the front pressure plate 56 and the rear pressure plate 57 is fixedly connected to the protective pad 58 respectively. The protective pad 58 plays an isolation and protection role to prevent the double-sided adhesive 4 from being damaged when the front pressure plate 56 and the rear pressure plate 57 press down. When the front pressure plate 56 and the rear pressure plate 57 press down, the protective pad 58 is tightly attached to the upper end of the double-sided adhesive 4.
[0023] Please see Figure 1 , Figure 4 The dust removal mechanism 6 includes a support frame 61. The upper end of the workbench 1 is fixedly connected to the support frame 61. The upper end of the support frame 61 is fixedly connected to a dust suction hood 62. The upper end of the dust suction hood 62 is fixedly connected to a flow guide hood 63. The upper end of the flow guide hood 63 is fixedly connected to a vacuum cleaner 64. The vacuum cleaner 64 is existing technology and will not be described in detail in this technical solution. The lower end of the vacuum cleaner 64 is fixedly connected to a suction pipe 65. The suction pipe 65 passes through the upper end of the flow guide hood 63.
[0024] The specific implementation process of this utility model is as follows: The double-sided tape 4 slides through the upper end of the workbench 1 and simultaneously slides through the lower ends of the front pressure plate 56 and the rear pressure plate 57. Then, the telescopic rod 52 can be activated. The telescopic rod 52 drives the hanging plate 53 to move downward, thereby the hanging plate 53 drives the connecting block 54 to move downward. The connecting block 54 drives the sliding rod 55 to move downward. At the same time, the sliding rod 55 is slidably connected to the workbench 1. Then, the downward movement of the sliding rod 55 drives the front pressure plate 56 and the rear pressure plate 57 to move downward, thereby moving the position to be cut to the upper end of the groove 3. Then, the lower pressure limit of the front pressure plate 56 and the rear pressure plate 57 is located at the upper end of the double-sided tape 4, so as to avoid the double-sided tape 4 moving during cutting and affecting the cutting work.
[0025] Simultaneously, the vacuum cleaner 64 is activated. As the vacuum cleaner 64 operates, the dust is sucked into the dust hood 62, and then moved to the suction pipe 65 through the dust hood 62 and the guide hood 63. Finally, the dust is moved to the vacuum cleaner 64 through the suction pipe 65. The dust hood 62 increases the absorption area, and the guide hood 63 guides and facilitates the movement of dust, thereby increasing the dust absorption effect.
[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
