Description

Technical Field

[0001] The utility model relates to the technical field of tape production, and particularly relates to a filter for tape production. Background Art

[0002] In the process of tape production, the glue in the hot melt tank needs to be injected into the coater. However, there are often some impurities in the glue, which affect the production quality of the tape. Therefore, it is necessary to filter the glue. Content of the Utility Model

[0003] The purpose of the utility model is to provide a filter for tape production aiming at the defects and deficiencies of the prior art.

[0004] To achieve the above purpose, the technical scheme adopted by the utility model is: a filter for tape production, including an outer cylinder and an inner filter cylinder. The innovation lies in that: one side of the outer cylinder is provided with a feed inlet, and the other side is provided with an installation hole. One side of the inner filter cylinder is an outlet, and the other side is a filtering part. The filtering part of the inner filter cylinder is embedded into the outer cylinder through the installation hole. An installation ring is arranged on the outer ring of the inner filter cylinder, and the installation ring is fixed to the outer cylinder by bolts. A sealing ring is arranged in the installation ring.

[0005] Further, the inner filter cylinder is of a split structure, and the two are fixed by flat head screws. A filter screen is arranged inside the part close to the outlet, and is fixed by bolts.

[0006] Further, a heating layer is wrapped outside the outer cylinder.

[0007] After adopting the above structure, the beneficial effects of the utility model are as follows:

[0008] The utility model can filter the inside of the glue by setting the inner filter cylinder, thereby improving the tape quality. At the same time, the inner filter cylinder can be disassembled for cleaning or replacement, improving the practicability; the inner filter cylinder and the filter screen achieve secondary filtration, further improving the product quality. At the same time, the inner filter cylinder is of a split structure, which is convenient for disassembling the filter screen for cleaning; the heating layer can prevent the glue from solidifying, facilitating the flow of the glue and being convenient for filtration.

[0011] 1 outer cylinder, 11 feed inlet, 2 inner filter cylinder, 21 outlet, 22 filtering part, 23 installation ring, 3 sealing ring, 4 filter screen, 5 heating layer. Detailed Embodiment

[0012] The following further describes the present utility model in conjunction with the accompanying drawings.

[0013] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0014] Refer to Figure 1 , a filter for tape production, comprising an outer cylinder 1 and an inner filter cylinder 2. An inlet 11 is provided on one side of the outer cylinder 1, and an installation hole is provided on the other side. One side of the inner filter cylinder 2 is an outlet 21, and the other side is a filtering part 22. The filtering part 22 of the inner filter cylinder 2 is embedded into the outer cylinder 1 through the installation hole. An installation ring 23 is arranged on the outer circle of the inner filter cylinder, and the installation ring 23 is fixed to the outer cylinder 1 by bolts. A sealing ring 3 is arranged inside the installation ring 23. Specifically, after the glue enters from the inlet 11, it enters the inner filter cylinder 2 through the filtering holes of the filtering part 22 and then is discharged from the outlet 21, thereby realizing glue filtration; the inner filter cylinder 2 is installed and disassembled through the installation ring 23 and bolts, and is used for cleaning or replacing the inner filter cylinder 2 later; the sealing ring 3 improves the sealing performance between the outer cylinder 1 and the inner filter cylinder 2 to prevent glue leakage.

[0015] In this embodiment, the inner filter cylinder 2 is of a split structure, and the two are fixed by flat head screws. A filter screen 4 is arranged inside the part close to the outlet, and is fixed by bolts. The split structure of the inner filter cylinder 2 facilitates the disassembly and cleaning of the filter screen 4; at the same time, the inner filter cylinder 2 and the filter screen 4 achieve secondary filtration, further improving the product quality.

[0016] In this embodiment, a heating layer 5 is wrapped outside the outer cylinder 1. The heating layer 5 can prevent the glue from solidifying, facilitate the flow of the glue, and is conducive to filtration.

[0017] The above is only used to illustrate the technical solutions of the present utility model and not to limit them. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solutions of the present utility model shall be covered within the scope of the claims of the present utility model as long as they do not depart from the spirit and scope of the technical solutions of the present utility model.
