A multifunctional raw material tape reel core

Abstract

This utility model discloses a multifunctional PTFE tape reel core, the structure of which includes: an auxiliary groove and a shell structure. The improved shell structure allows the PTFE tape to be wound in a ring by a winding rod, and then, together with a side disc, embedded in the contact wall inside the edge shell to achieve a dustproof effect on the side and edge. The contact wall shell, combined with a restraining ring and a blocking block, restrains the side disc, allowing the side disc and winding rod to rotate stably, pulling the PTFE tape straight out from the output head. After the PTFE tape is used, it is hooked into a dedicated hook position through the hook groove at the front end, facilitating storage and preventing it from being mixed with other tools in the storage box and becoming difficult to find. Furthermore, the limiting frame set at the edge of the cutting groove at the front end of the output head improves the stable pulling effect of the PTFE tape. The small blade mounted on the inner wall of the limiting frame cuts the PTFE tape after use, replacing the irregular situation caused by direct pulling and tearing.

Description

Technical Field

[0001] This utility model relates to the technical field of raw material tape reel cores, specifically a multifunctional raw material tape reel core. Background Technology

[0002] PTFE tape is a sealing material made of polytetrafluoroethylene (PTFE). It is mainly used to enhance the sealing performance of pipe connections. When in use, PTFE tape can be inserted into a special reel for positioning. The reel and reel work together to ensure that the PTFE tape can be pulled out in a stable state. The reel and reel work together to improve the ease of use of PTFE tape.

[0003] However, the existing reel cores still have the following drawbacks: due to the relatively simple structure of the current reel cores, they only provide positioning of the raw material tape and facilitate its rotation and pulling out, without any other practical auxiliary functions.

[0004] Firstly, after the raw material tape is inserted, it is easily contaminated by dust in the air due to the open edges, which reduces the cleanliness of the raw material tape.

[0005] Secondly, after the raw material tape is used up, the current reel core is stored flat in the relevant storage box, which makes it difficult to find when it is mixed with other tools.

[0006] Thirdly, when the PTFE tape is rotated and pulled out for use, it is directly torn off after being wound around the pipe to the appropriate thickness. This results in irregular winding at the break point of the PTFE tape, which reduces the accuracy of subsequent smooth winding. Utility Model Content

[0007] To address the above problems, this utility model provides a multifunctional raw material tape reel core.

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution: a multifunctional raw material tape reel core, the structure of which includes: an auxiliary groove and a shell structure, wherein the auxiliary groove is perpendicularly inserted through the center of the shell structure and is circular in shape.

[0009] Furthermore, the outer shell structure is provided with a winding rod, on which side plates are mounted at the upper and lower positions and embedded inside the edge shell. The edge shell is equipped with an output head as an integrated structure. Hook grooves are opened at the upper and lower positions of the front end of the output head, and a cutting groove is opened on the front end surface of the output head. A restraining ring is also provided at the upper and lower positions of the edge shell surface to cover the edge of the contact wall. A blocking block is fixed on the surface of the contact wall to contact the inner side of the side plate and communicate with the cutting groove of the output head.

[0010] Furthermore, the outer shell structure carries the raw material tape into the edge shell and contacts the contact wall through the winding rod of the side plate. At the same time, the inner edge of the side plate is restricted by the blocking block, and then the raw material tape is pulled to the cutting groove position and pulled out through the output head.

[0011] Furthermore, the winding rod and the side plate form an "I" shape, with the side plate covering the upper and lower positions of the winding rod. The edge shell covers the edge of the winding rod through the side plate. The restraining ring of the edge shell limits the upper and lower positions of the contact wall. Two arc-shaped blocking blocks are fused to the contact wall and set in a symmetrical orientation. The front end of the output head mounted on the edge of the edge shell has a rounded corner shape and is penetrated by a cutting groove.

[0012] Furthermore, the cutting groove is also provided with a limiting frame, the inner wall of which is equipped with a small blade and has a slot. A protective sleeve is also provided inside the limiting frame, and the left and right sides of the protective sleeve are inserted into the slot to cover the surface of the small blade.

[0013] Furthermore, the limiting frame is rectangular in shape and contains two sets of solid small blades set symmetrically. There is a slot on each side of the small blades and they are spaced together. The protective sleeve is longer than the small blades and has protrusions at both ends. It is inserted into the slots and interlocks with the limiting frame. Beneficial effects

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model improves the outer shell structure by using a winding rod to wind the raw material tape in a ring. Then, together with the side plate, it is embedded in the contact wall inside the edge shell to achieve the effect of covering and preventing dust on the side and edge. Furthermore, the contact wall shell, combined with the restraining ring and the blocking block, restrains the side plate, so that the side plate and the winding rod rotate stably and the raw material tape is pulled out in a straight line from the output head.

[0016] 2. With the improved output head, the upper and lower hook slots at the front end allow the raw material tape to be directly hung in the dedicated hook position after use, making it easy to store and preventing it from being mixed with other tools in the storage box and becoming difficult to find.

[0017] 3. This utility model improves upon the cutting groove at the front end of the output head by using a limiting frame set at the edge of the cutting groove to enhance the stable pulling effect of the PTFE tape. The two small blades mounted on the inner wall of the limiting frame can cut the PTFE tape after use, replacing the irregular situation caused by direct pulling and tearing. This improves the convenience of subsequent use of the PTFE tape. The small blades can be covered by a protective sleeve and then inserted into the slot to be fixed with the limiting frame, preventing them from falling off or causing scratches.

[0026] Example

[0027] like Figures 1-3 As shown

[0028] This utility model provides a multifunctional raw material tape reel core.

[0029] Its structure includes: an auxiliary groove 1 and an outer shell structure 2. The auxiliary groove 1 is perpendicular to the center of the outer shell structure 2 and is circular in shape.

[0030] The outer shell structure 2 is provided with a winding rod 21. The winding rod 21 is equipped with a side plate 22 at its upper and lower positions and is embedded inside the edge shell 23. The edge shell 23 is equipped with an output head 24 as an integrated structure. The output head 24 has a hook groove 25 at its upper and lower front end and a cutting groove 26 at its front end surface. The edge shell 23 is also provided with a restraining ring 27 at its upper and lower positions to cover the edge of the contact wall 28. The contact wall 28 is fixed with a blocking block 29 that contacts the inner side of the side plate 22 and communicates with the cutting groove 26 of the output head 24.

[0031] The outer shell structure 2 carries the raw material tape through the winding rod 21 of the side plate 22 and embeds it into the edge shell 23 to contact the contact wall 28. At the same time, the inner edge of the side plate 22 is restricted by the blocking block 29, and then the raw material tape is pulled to the cutting groove 26 position by the output head 24 and pulled out.

[0032] The winding rod 21 and the side plate 22 form an "I" shape. The side plate 22 covers the upper and lower positions of the winding rod 21. The edge shell 23 covers the edge of the winding rod 21 through the side plate 22. The restraining ring 27 of the edge shell 23 limits the upper and lower positions of the contact wall 28. Two arc-shaped blocking blocks 29 are integrated on the contact wall 28 and set in a symmetrical position. The output head 24 mounted on the edge of the edge shell 23 has a rounded corner at the front end and is penetrated by the cutting groove 26.

[0033] The cutting groove 26 is also provided with a limiting frame 261. The inner wall of the limiting frame 261 is equipped with a small blade 262 and has a slot 263. The limiting frame 261 is also provided with a protective sleeve 264. The left and right sides of the protective sleeve 264 are inserted into the slot 263 to cover the surface of the small blade 262.

[0034] The limiting frame 261 is rectangular and contains two sets of solid small blades 262 arranged symmetrically. The slots 263 are located on the left and right sides of the small blades 262 and are spaced together. The protective sleeve 264 is longer than the small blades 262 and has protrusions at both ends. It is inserted into the slots 263 and interlocks with the limiting frame 261.

[0035] The working principle of this utility model is explained as follows: The outer shell structure 2 of the multi-functional PTFE tape reel core can be used handheld via the auxiliary groove 1. Furthermore, the contact wall 28 inside the edge shell 23 of the outer shell structure 2 can be used with the restraining ring 27, allowing the "I" shape formed by the side disc 22 and the winding rod 21 to be embedded in the contact wall 28. Therefore, after the side disc 22, in conjunction with the winding rod 21, positions the PTFE tape, when the side disc 22 is embedded in the contact wall 28 and restrained by the blocking block 29, it can achieve balanced rotation inside the edge shell 23, preventing it from falling off. Simultaneously, the combined coverage of the side disc 22 and the edge shell 23 achieves a dustproof effect, preventing pollution from dust intrusion. Subsequently, the output head 24 at the edge of the edge shell 23 guides the PTFE tape from the winding rod 21 to the cutting groove 26. This allows the PTFE tape to be pulled out stably for use. After use, it can be directly hooked into a dedicated hook position through the hook slots 25 at the front end of the output head 24, instead of being placed directly into the storage box and mixed with other tools, making it difficult to find. The small blade 262 fixed to the inner wall of the limiting frame 261 set in the cutting groove 26 can stably output the PTFE tape through the spacing. After the PTFE tape is used up, the protective sleeve 264 is taken out from the slot 263, allowing the PTFE tape to contact the small blade 262 to achieve parallel cutting, replacing the irregular situation caused by direct tearing, thus improving the flatness of the PTFE tape cut. Then, the protective sleeve 264 is put back on the surface of the small blade 262 and spliced ​​with the slot 263 of the limiting frame 261 to prevent scratches.

[0036] In summary, the cooperation of various components can effectively improve the strength of the raw material tape reel core and achieve the desired multi-functionality.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
