Description

Technical Field

[0001] The utility model relates to the technical field of mold manufacturing, in particular to a die-cutting device for substrate-free double-sided adhesive tape. Background Art

[0002] The die-cutting device for double-sided adhesive tape is a professional equipment specially used for precisely processing double-sided adhesive tape. It integrates multiple key parts such as a unwind mechanism, a die-cutting component, a moving mechanism, an adjusting mechanism, a conveying and guiding component, and a collecting component. Its main purpose is to efficiently and precisely process continuous double-sided adhesive tape rolls into products of various specific shapes and sizes to meet diverse application requirements.

[0003] The existing Chinese patent (Publication No.: CN218699638U) discloses a substrate-free double-sided adhesive tape die-cutting device. The output shaft of the second motor can make the lead screw rotate, and the lead screw can make the connecting plate move horizontally through a lead screw nut, and then the infrared sensor can move horizontally. Due to the setting of a scale, the distance between the infrared sensor and the die-cutting knife can be accurately adjusted, so that double-sided adhesive tape bodies of different sizes can be die-cut;

[0004] When the above patent is used, through the detection of the infrared sensor, the starting point and stopping point of die-cutting can be determined more precisely, thereby improving the accuracy and precision of die-cutting and reducing errors. However, this device relies too much on the positioning of the infrared sensor. During the cutting process, the cut-off waste materials are very likely to block the infrared sensor, causing it to sense incorrect data. If the infrared sensor is blocked, when the die-cutting knife performs die-cutting operations, it will inevitably lead to a blurred separation boundary between the cut raw materials and the waste materials. Such an unclear connection situation will undoubtedly greatly increase the possibility of the raw materials being adhered and taken away by the waste materials. Summary of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0032] A die-cutting device for substrate-free double-sided tape includes an installation box 1 and a first cutter 212 and a second cutter 213 arranged in the installation box 1, and a transmission assembly 2 is arranged on the installation box 1;

[0033] The transmission assembly 2 includes an airbag 22, a first cutting bin 21 is fixedly communicated with the airbag 22, a rubber plate 23 is slidably connected to the first cutting bin 21, a second expansion bin 25 is fixedly connected to the rubber plate 23, a first expansion bin 24 is slidably connected to the second expansion bin 25, a mechanical telescopic rod 210 is slidably connected in the second expansion bin 25, a rotating part 211 is rotatably connected to the mechanical telescopic rod 210, and one end of the rotating part 211 away from the mechanical telescopic rod 210 is fixedly connected to the second expansion bin 25;

[0034] In the present utility model, the working principle of the die-cutting device brings many beneficial effects. Firstly, the automation of raw material transportation and cutting is realized. The second motor 51 transports the raw materials, and the first motor 4 and the electric telescopic rod 41 complete the cutting, greatly improving the production efficiency and reducing the labor cost. Secondly, the cut pieces are effectively separated from the scraps. The second cutting bin 44 presses down to make the rubber plate 23 rise to adsorb the cut pieces, and the second expansion bin 25 expands to lift the cut pieces, and the scraps are taken out, ensuring the product quality and solving the problem in the prior art in the background technology that the scraps are likely to take away the cut pieces after processing.

[0035] A rotating shaft 11 is rotatably connected to the mounting box 1, and a mounting door 12 is rotatably connected to the rotating shaft 11. The second expansion bin 25, the mechanical telescopic rod 210, and the side of the first expansion bin 24 away from the mounting box 1 are all fixedly connected to the airbag 22. An arc-shaped member 28 is slidably connected to the airbag 22. A reset member 26 is fixedly connected to the arc-shaped member 28. A first spring 27 is fixedly connected to the arc-shaped member 28. The end of the first spring 27 away from the airbag 22 is fixedly connected to the peripheral bin 29. By arranging that the second expansion bin 25 and the bottom of the mechanical telescopic rod 210 are fixed on the airbag 22, when in use, when the rubber plate 23 slides upward, the second expansion bin 25 can be driven to expand, so that the rotating member 211 rotates on the mechanical telescopic rod 210, and the second expansion bin 25 is driven to expand;

[0036] A sliding groove is formed in the first cutter 212, and the second cutter 213 is slidably connected to the sliding groove in the first cutter 212. A second cutting bin 44 is arranged in the mounting box 1. A transmission rope 42 is slidably connected to the second cutting bin 44.

By arranging the second springs 214, when the transmission rope 42 is loose, the first cutters 212 can be reset, and the first cutters 212 can be linked together;

[0037] Both ends of the transmission rope 42 are fixedly connected to two of the four first cutters 212 that are far away from the reset member 26. By arranging that the transmission rope 42 is fixed to the first cutters 212 at both ends, when in use, the two transmission members can be tightened by the first transmission member, so that the four first transmission members can achieve a linkage effect under the joint action of the transmission rope 42 and the second spring 214.

[0038] In the above solution, there is also a problem that the power source of the transmission rope 42 is not proposed, such as Figure 1 、 Figure 2 、 Figure 5As shown in the figure, an electric telescopic rod 41 is drivingly connected to a transmission rope 42. The top of the electric telescopic rod 41 is fixedly connected to a rotating column 43. The electric telescopic rod 41 is fixedly connected to a second cutting bin 44. A first motor 4 is fixedly connected to the rotating column 43. A fixed bin is fixedly connected to the first motor 4. The fixed bin on the first motor 4 is fixedly connected to the top of the installation box 1. By providing the first motor 4 to control the rotation of the rotating column 43, the automation degree is relatively high and the controllability is relatively high. The function of the fixed bin is to fix the motor and prevent it from rotating by itself;

[0039] The bottom of the airbag 22 is fixedly connected to an outer peripheral bin 29. The bottom of the outer peripheral bin 29 is fixedly connected to a placement plate 3. The bottom of the placement plate 3 is fixedly connected to a mounting plate 31. The bottom of the mounting plate 31 is fixedly connected to a bottom plate 5. A support frame is fixedly connected to the bottom plate 5. A second motor 51 is fixedly connected to the support frame on the bottom plate 5. A first transmission roller 52 is fixedly connected to the second motor 51. Four support frames are provided on the support frame of the bottom plate 5. A second transmission roller 53 is rotatably connected between two support frames on the bottom plate 5 that are far away from the second motor 51. By providing the first transmission roller 52 and the second transmission roller 53, during use, the feeding process can be performed through the first transmission roller 52 and the second transmission roller 53. The second motor 51 drives the first transmission roller 52 to realize feeding of the raw materials wound on the first transmission roller 52 and the second transmission roller 53.

[0040] Working principle:

[0041] As Figures 1-5As shown in the figure: during use, first wind the raw material around the first driving roller 52 and the second driving roller 53. Then, start the second motor 51 to drive the first driving roller 52 to rotate, and convey the raw material into the installation box 1. Start the first motor 4, and the first motor 4 drives the rotating column 43 to rotate, so that the transmission rope 42 winds around the electric telescopic rod 41, causing the second cutting knife 213 to slide on the first cutting knife 212. Then, by starting the electric telescopic rod 41, the electric telescopic rod 41 drives the second cutting bin 44 to press down, realizing the cutting of the raw material. During this process, the second cutting bin 44 presses the reset part 26, and the reset part 26 drives the arc-shaped part 28 on the second cutting bin 44, so that the rubber plate 23 is pushed upward. The rubber plate 23 will adsorb the cut pieces of the raw material, and the remaining scraps are continuously taken out under the driving of the second motor 51, realizing the separation of the spacer and the raw material. During the upward movement of the rubber plate 23, when the rubber plate 23 slides upward, it can drive the second expansion bin 25 to expand, causing the rotating part 211 to rotate on the mechanical telescopic rod 210, driving the second expansion bin 25 to expand. The grid-like space formed by the first cutting knife 212 and the second cutting knife 213 will block the first expansion bin 24 and the second expansion bin 25, realizing the lifting of the cut pieces of the raw material, and further ensuring that the spacer is completely separated from the scraps.
