Description

Technical Field

[0001] This utility model belongs to the field of high temperature resistant materials technology, and in particular relates to a high temperature resistant tape with temperature warning function. Background Technology

[0002] High-temperature resistant tape is an industrial material designed specifically for extreme temperature environments. It is most widely used in the automotive and aerospace industries. High-temperature resistant tape mainly consists of two parts: the high-temperature resistant tape body and the take-up drum. The high-temperature resistant tape body is wound on the outer wall of the take-up drum in a layered winding manner.

[0003] Chinese patent application CN223016044U discloses a high-melting-point, high-temperature resistant adhesive tape, comprising a tape body mounted on a take-up drum. A fixing rod is installed inside the take-up drum, and a smoothing mechanism is provided on the take-up drum. The smoothing mechanism includes a fixing frame, and a tension member is provided between the fixing frame and the fixing rod to ensure the fixing frame is tightly attached to the tape body, preventing the tape body from curling at the edges. After the tape body is used, the tension member drives the fixing frame to tightly adhere to the end of the tape body, ensuring the tape body edge is firmly attached to the tape body, preventing curling at the edges. This not only facilitates later use but also saves resources. Furthermore, the position of the fixing frame corresponds to the position of the tape body end, helping users quickly locate the accurate position of the tape end for easy tearing, thus improving tape usage efficiency.

[0004] The aforementioned high-melting-point high-temperature resistant tape comprises a wear-resistant layer and an adhesive layer, with a reinforcing layer between the wear-resistant layer and the adhesive layer. A heat-resistant component layer, including a first heat-resistant layer, a second heat-resistant layer, and a third heat-resistant layer, is also provided between the adhesive layer and the reinforcing layer. After use, as the temperature gradually increases, the tape body undergoes a certain degree of heat melting from the inside out, causing severe damage to the tape body. When the tape body is damaged internally but intact externally, it is impossible to determine whether it needs replacement. Furthermore, because the tape body is adhered to the outer wall of a hollow cylindrical roll without any side guards, some adhesive overflows from the sides of the tape body during the layering process, resulting in dust accumulation on the sides. Therefore, we provide a high-temperature resistant tape with a temperature warning function to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a high-temperature resistant tape with a temperature warning function. By using protective components, both ends of the tape body wound on the take-up drum can be protected. Through the heat-sensitive coating on the tape body, the color of the tape body will change when subjected to different temperatures, thereby achieving a temperature warning effect and solving the problems of the aforementioned high-melting-point high-temperature resistant tape.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a high-temperature resistant tape with a temperature warning function, comprising a take-up drum; the take-up drum has an internal skeleton and a protective component at its end, the protective component including a protective ring at the outer end of the take-up drum, and an insert plate inserted into the protective ring, the protective ring being inserted into the end of the take-up drum through the insert plate, the take-up drum also having a tape body wound on it, the tape body being composed of a high-temperature resistant layer one, a high-temperature resistant layer two, and a high-temperature resistant layer three, the bottom of the high-temperature resistant layer one having an adhesive layer, the outer side of the high-temperature resistant layer three having a reinforcing layer, and the interior of the reinforcing layer having a heat-sensitive coating.

[0008] The present invention is further configured such that side grooves are provided on the outer walls of both ends of the winding drum, and slots are provided inside the side grooves. A total of four slots are provided, and the four slots are arranged in a ring array structure.

[0009] The present invention is further configured such that there are two protective components, which are respectively disposed at the ends of the winding drum, and the protective ring is disposed on the outside of the side groove and covers the outer wall of the side groove.

[0010] The present invention is further configured such that the protective ring has a sliding groove, and there are four sliding grooves in total. The four sliding grooves are arranged in a ring array structure, and the sliding grooves and the slots are arranged opposite to each other.

[0011] The present invention is further configured such that the insert plate is slidably inserted into the slide groove, and both the insert plate and the slide groove are T-shaped, and the length of the insert plate is greater than the length of the slide groove.

[0012] The present invention is further configured such that springs are fixedly installed on the two end side walls of the horizontal section of the slide, and the other end of the springs is connected to the two end bottom side walls of the horizontal section of the insert plate. A lifting groove is also provided on the outer side wall of the insert plate.

[0013] The present invention is further configured such that the second high-temperature resistant layer is disposed between the first high-temperature resistant layer and the third high-temperature resistant layer, the first high-temperature resistant layer is bonded to a predetermined high-temperature position through an adhesive layer, and the third high-temperature resistant layer is connected to the external environment through a reinforcing layer.

[0014] The present invention is further configured such that the heat-sensitive coating is disposed on the central axis of the reinforcing layer, and the heat-sensitive coating is disposed between the high-temperature resistant layer and the reinforcing layer.

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

[0016] 1. This utility model incorporates protective components on both sides of the take-up drum. Side grooves are formed at both ends of the take-up drum, and slots are formed within these side grooves. Each protective component includes a protective ring fitted onto both ends of the take-up drum. A sliding groove is formed within the protective ring, and an insert plate is slidably inserted into the groove. Springs are installed at both ends of the bottom sidewall of the upper end of the insert plate, with the other end of the spring connected to the inner wall of the upper end of the sliding groove. In use, pulling the insert plate outwards pulls the spring outwards, causing the insert plate to move outwards along the sliding groove until its end disengages from the inner wall of the protective ring. The protective ring is then inserted from one end of the take-up drum, just covering the side groove. Releasing the insert plate causes the spring to lose its restraining force and return to its initial state, allowing the insert plate to move downwards in the sliding groove until its end passes through the inner wall of the protective ring and extends into the slot of the take-up drum. This achieves the effect of fixing the protective ring to the end of the take-up drum and also provides shielding for both sides of the tape body.

[0017] 2. This utility model features an adhesive tape body composed of a high-temperature resistant layer one, a high-temperature resistant layer two, and a high-temperature resistant layer three. The bottom of the high-temperature resistant layer one has an adhesive layer, which allows the tape body to be adhered to a predetermined high-temperature location. The outer side of the high-temperature resistant layer three has a reinforcing layer, which increases the hardness of its outer surface and prevents puncture. A heat-sensitive coating is located along the central axis of the reinforcing layer. During use, the adhesive layer side is aligned with the predetermined high-temperature location to be adhered. Then press the tape body to ensure the integrity of the tape body adhesion. As the temperature of the adhered area gradually increases, the high temperature will be transferred from the bottom adhesive layer to the high temperature resistant layer one, high temperature resistant layer two, and high temperature resistant layer three in sequence. When the temperature of the high temperature resistant layer three rises, because the thermosensitive coating is made of thermosensitive color-changing material, its color will change when subjected to different temperatures. By observing the color change of the thermosensitive coating, the temperature of the tape body at that location can be determined, thereby achieving a temperature warning effect.

Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] Example 1

[0028] Please see Figure 1-4 This utility model is a high-temperature resistant tape with temperature warning function, including a take-up drum 1 and a protective component 3. The protective component 3 can be used to protect both ends of the tape body 4 wound on the take-up drum 1.

[0029] Specifically, the take-up drum 1 has side grooves 101 on both sides, and slots 101a are provided in the side grooves 101. The take-up drum 1 has a frame 2 inside, and protective components 3 are provided on both ends of the take-up drum 1 and on the side grooves 101.

[0030] Furthermore, the protective component 3 includes a protective ring 301 covering the side groove 101. The protective ring 301 has a sliding groove 301a, which is opposite to the slot 101a. There are four sliding grooves 301a and four slots 101a, and the four sliding grooves 301a and the four slots 101a are arranged in a ring array structure. An insert plate 302 is also inserted into the sliding groove 301a. A lifting groove 302a is provided on the outer side wall of the insert plate 302. Springs 302b are installed at both ends of the bottom side wall of the upper end of the insert plate 302. The other end of the spring 302b is connected to the inner wall of the upper end of the sliding groove 301a.

[0031] The operation process of this embodiment is as follows: When in use, pull the insert plate 302 and pull it outward. At this time, the spring 302b is pulled outward, and the insert plate 302 also moves to the outside of the slide groove 301a until the end of the insert plate 302 is separated from the inner wall of the protective ring 301. At this time, insert the protective ring 301 from one end of the take-up drum 1 and make the protective ring 301 just cover the side groove 101. Then release the insert plate 302. At this time, the spring 302b loses the restraining force of the pull and returns to the initial state. That is, the insert plate 302 moves down in the slide groove 301a until the end of the insert plate 302 passes through the inner wall of the protective ring 301 and extends into the slot 101a of the take-up drum 1. This achieves the effect of fixing the protective ring 301 to the end of the take-up drum 1 and also achieves the effect of covering both sides of the tape body 4.

[0032] Example 2

[0033] Please see Figure 5 Based on Example 1, a tape body 4 is also provided. Through the heat-sensitive coating 405a on the tape body 4, the color of the tape body 4 changes when it is subjected to different temperatures, thereby achieving a temperature warning effect.

[0034] Specifically, the outer side of the take-up drum 1 is also wrapped with a tape body 4, which is composed of a high-temperature resistant layer 1 402, a high-temperature resistant layer 2 403 and a high-temperature resistant layer 3 404.

[0035] Furthermore, a second high-temperature resistant layer 403 is disposed between a first high-temperature resistant layer 402 and a third high-temperature resistant layer 404. An adhesive layer 401 is disposed at the bottom of the first high-temperature resistant layer 402, and a reinforcing layer 405 is disposed on the outer side of the third high-temperature resistant layer 404. A thermosensitive coating 405a is disposed on the central axis of the inner part of the reinforcing layer 405. The thermosensitive coating 405a is made of a thermosensitive color-changing material. The first high-temperature resistant layer 402, the second high-temperature resistant layer 403, the third high-temperature resistant layer 404, and the reinforcing layer 405 have already been disclosed in a high-melting-point high-temperature resistant tape disclosed in Chinese patent application CN223016044U mentioned in the background art, and will not be described in detail here.

[0036] The operation process of this embodiment is as follows: When in use, align one side of the adhesive layer 401 with the predetermined high-temperature position to be bonded, and then press the tape body 4 to ensure the integrity of the adhesive. As the temperature of the bonded position gradually increases, the high temperature will be transferred from the bottom adhesive layer 401 to the high-temperature resistant layer 402, the high-temperature resistant layer 403, and the high-temperature resistant layer 404 in sequence. When the temperature of the high-temperature resistant layer 404 increases, since the thermosensitive coating 405a is made of thermosensitive color-changing material, the color of the thermosensitive coating 405a will change when subjected to different temperatures. By observing the color change of the thermosensitive coating 405a, the temperature of the tape body 4 at that location can be determined, thereby achieving a temperature warning effect.
