Description

Technical Field

[0001] The utility model belongs to the technical field of adhesive tape slitting, in particular to a multi-size precise slitting device for adhesive tape production. Background Art

[0002] Adhesive tape is a material composed of a base material and an adhesive. It connects two or more unconnected objects together by bonding. A layer of adhesive is coated on its surface. The adhesive can stick to things because bonds are formed between its own molecules and the molecules of the connected objects. This bond can firmly bond the molecules together. In order to adapt to different usage environments, it is often cut into different sizes after production.

[0003] At present, there are two existing tape slitting methods: one is to slitting during the conveying path during the winding process, and the other is to slitting after the winding is completed;

[0004] However, in the actual production process, it was found that the above two methods evenly left adhesive residue on the outside of the conductor, which could not be directly removed. The increase of adhesive would also affect the precision of the slitting size, thereby reducing the quality of the product.

[0005] In order to solve the above problems, the present application proposes a multi-size precision slitting device for tape production. Utility Model Content

[0006] The purpose of the utility model is to provide a multi-size precision slitting device for adhesive tape production, which solves the problems raised in the above-mentioned background technology.

[0009] Furthermore, a positioning plate is provided at one end of the first electric retractor, and an annular sleeve is slidably mounted on one side of the positioning plate.

[0010] Furthermore, the blocking portion is inserted into the inner positioning groove through the annular sleeve to form an outward extrusion force to produce expansion deformation.

[0011] Furthermore, a second electric retractor is provided on one side of the annular sleeve, one end of which is connected to the annular sleeve.

[0012] Furthermore, pressure plates for clamping the isolation membrane are arranged inside the two sides of the upper end of the tool holder, and the lower end of the isolation membrane is inserted into the groove on the side of the cutting knife at the bottom of the tool holder. A third electric retractor is also arranged inside the two sides of the upper end of the tool holder.

[0013] Furthermore, a limiting groove for installing a roller is provided inside the tool holder.

[0014] Furthermore, the fixing seat is squeezed by the rubber roller to form a clamping edge.

[0015] The utility model has the following beneficial effects:

[0016] The utility model can block the adhesive and prevent continuous overflow by using the isolation film to contact the cross section of the adhesive tape when cutting the adhesive tape, and then wrap the two ends of the adhesive tape, which is convenient for subsequent storage and transportation. Compared with the existing method, it can effectively avoid a large amount of adhesive residue on the blade surface, ensure the stability of long-term cutting operation, and improve the production quality of the adhesive tape;

[0017] The utility model can directly extrude the fixed inner side outward at different positions through the double telescopic structure, thereby the inner side support position can be quickly adjusted according to the slitting position to enhance the stability of the structure and prevent deformation caused by the squeezing force, making the slitting process more stable and conducive to large-scale production operations.

[0028] See also Figure 1-4 As shown, the utility model is a multi-size precision slitting device for adhesive tape production, comprising: a base 1 and a slide seat 2 slidably mounted on the upper end thereof, and a rubber roller 3 is mounted on the inner side of the slide seat 2;

[0029] A knife holder 4 is provided above the base 1 to prevent adhesive residue, and isolation films 5 are provided on both sides of the knife holder 4 to isolate adjacent adhesive tapes after slitting. A limiting groove 15 is provided inside the knife holder 4, and a roller 12 is installed inside the knife holder 4 to reduce the friction resistance between the isolation film 5 and the isolation film 5, so that the knife holder 4 can fit the isolation film 5 to the cross section of the rubber roller 3 after slitting, and the knife holder 4 can be easily pulled out;

[0030] A fixing seat 6 for mounting the rubber roller 3 is arranged inside the slide seat 2, and a first electric retractor 7 is arranged at one end of the fixing seat 6. The expansion of the blocking portion 8 at the end of the first electric retractor 7 supports the inner side of the rubber roller 3 to prevent deformation during slitting;

[0031] The present embodiment provides a tape slitting mechanism for preventing adhesive residue. An isolation film 5 is used to replace the section where the blade contacts the rubber roller 3, which can effectively prevent the adhesive from adsorbing the blade, making the subsequent slitting operation more stable. Secondly, the rubber roller 3 is supported by a blocking portion 8 inside, which can enhance the structural stability and prevent deformation.

[0032] Among them, a positioning plate 9 is arranged at one end of the first electric telescopic device 7, and an annular sleeve 10 is slidably mounted on one side of the positioning plate 9, one end of which is an inclined guide slope structure.

[0033] The blocking portion 8 is inserted into the inner positioning groove 16 through the annular sleeve 10 to form an outward extrusion force to produce expansion deformation to resist the inner side of the rubber roller 3, filling the hollow structure so that the outer layer area is more stable when under pressure.

[0034] A second electric expander 11 is disposed on one side of the annular sleeve 10 , one end of which is connected to the annular sleeve 10 for driving the second electric expander 11 to adjust the expansion state of the blocking portion 8 .

[0035] Among them, pressure plates 13 for clamping the isolation membrane 5 are arranged inside the upper sides of the tool holder 4, and the lower end of the isolation membrane 5 is inserted into the groove on the side of the cutting knife at the bottom of the tool holder 4. A third electric retractor 14 is also arranged inside the upper sides of the tool holder 4.

[0036] A limiting groove 15 for mounting the roller 12 is provided inside the tool holder 4 .

[0037] The fixing seat 6 is squeezed by the rubber roller 3 to form a clamping edge 17 .

[0038] It can be understood that the utility model can directly seal the cross-section of the rubber roller 3 through the isolation film 5 during the slitting operation to prevent the adhesive from overflowing, which is beneficial to the subsequent slitting operation mechanical energy of the knife body and convenient for storage and transportation. Secondly, it can also position the slitting area during the slitting operation to form a stable support for the inner side of the rubber roller 3 to prevent deformation.

[0039] A specific application of the operating process of this embodiment is as follows: when in use, first place the isolation film on both sides of the tool holder 4, so that the lower end is inserted into the inner side of the cutter at the lower end of the tool holder 4, and the upper end is tightened and fixed by the pressing plate 13, and then the support position of the blocking part 8 is adjusted by the first electric retractor 7, and then the annular sleeve 10 is pushed out by the second electric retractor 11. At this time, the annular sleeve 10 is inserted into the interior of the positioning groove 16 to press the blocking part 8 outward, so that it is tightly against the inner surface of the rubber roller 3 to form a stable support to prevent deformation during the slitting operation. Finally, during the slitting process of the tool holder 4, the isolation film 5 is used to contact the cross section of the rubber roller 3 to prevent a large amount of adhesive from remaining on the surface of the knife body, which is beneficial to the continuous slitting operation while reducing the difficulty of maintenance to facilitate the subsequent slitting operation.
