Description

Technical Field

[0001] The utility model relates to the technical field of TP, in particular to a TP double-sided adhesive protective film. Background Art

[0002] According to the scope of application, protective films can be used in the following fields: metal product surfaces, coated metal product surfaces, plastic product surfaces, automotive product surfaces, electronic product surfaces, sign product surfaces, profile product surfaces, and other product surfaces. In the production process of TP, double-sided adhesive protective films are usually attached to it to achieve transportation protection.

[0003] As the instruction manual Figure 1 As shown, it is a traditional double-sided adhesive design method, which is specifically as follows: usually, a double-sided adhesive (1-1) is added to the back of the TP, and a protective film (1-4) needs to be added separately to protect the TP sensor to avoid dirt. However, in the actual production operation process, it is found that if the inner protective film (1-4) is applied first, the double-sided adhesive (1-1) cannot be rolled up and is easy to press the protective film. If the double-sided adhesive (1-1) is applied first, the protective film (1-4) cannot be rolled up and will be pressed by the double-sided adhesive (1-1). In addition, since multiple protective films need to be synchronized to achieve the protection of the TP, it is easy to cause the complexity of the process and lead to a decrease in the yield rate. At the same time, the provision of multiple protective films makes it inconvenient to tear them off later. For this reason, the utility model proposes a TP double-sided adhesive protective film. Utility Model Content

[0004] Based on this, it is necessary to provide a TP double-sided adhesive protective film to address the above technical problems. By combining multiple protective films into a single protective film, TP can be protected, solving the problem that traditional double-sided adhesives require the design of multiple protective films and are inconvenient for subsequent winding.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A TP double-sided adhesive protective film, including a double-sided adhesive release film, comprising:

[0007] An edge film is formed at the edge of the double-sided release film;

[0008] An inner film, which is located inside the edge film and together with the edge film forms a double-sided adhesive release film;

[0009] The easy-tear unit is arranged on the double-sided adhesive release film and is used for independently tearing off the double-sided adhesive release film.

[0010] Furthermore, the tearable unit is a tearable handle, which has a handle body, a handle end and a handle tail. The handle body, the handle end and the handle tail are connected end to end in sequence to form a tearable handle, and both ends of a side surface of the handle end have arc chamfers.

[0011] Furthermore, the double-sided release film has a groove body matched with the easy-tear handle, and the easy-tear handle is integrally formed with the double-sided release film through the groove body.

[0012] Furthermore, a pre-cut line is punched out at the connection between the outer circumference of the handle body and the handle end and the double-sided release film.

[0013] Furthermore, stress release holes are punched out at the connection between the two ends of the handle tail away from one side of the handle body and the double-sided release film, and two pre-breaking lines are punched out along both sides of the stress release hole along the handle tail.

[0014] Furthermore, a connection between the handle body and the handle end is pre-pressed to form a pre-folding line 1, and a connection between the handle body and the handle tail is pre-pressed to form a pre-folding line 2.

[0015] Furthermore, the handle body, the handle end and the handle tail in the easy-tear handle are all located in the same plane as the double-sided release film, and the easy-tear unit is arranged on the inner film.

[0016] Furthermore, both sides of the easy-tear handle have adhesive layers corresponding to the double-sided release films.

[0017] Furthermore, the back side of the handle has a sticking area, and the handle is stuck to the double-sided release film through the sticking area;

[0018] The surfaces of the handle body and the handle end are both smooth planes, and the connection between the handle body and the handle tail is pre-pressed to form a pre-folding line three.

[0019] Furthermore, the plurality of double-sided release films and the easy-tear units thereon can be sequentially connected and rolled up to form a roll-shaped rolled state.

[0020] Compared with the prior art, the utility model has the following beneficial effects:

[0021] The TP double-sided adhesive protective film provided by the utility model combines multiple protective films into a single double-sided adhesive release film on the basis of the traditional protective film, eliminating the problem of the traditional need to attach multiple protective films in sequence. At the same time, only with the design of a single easy-tear unit, the entire TP film can be torn off, which facilitates the attachment and subsequent removal of the double-sided adhesive release film.

[0022] At the same time, because a single sheet of double-sided adhesive release film is used as the protective film of TP, multiple protective films can be relatively rolled up during the actual production process, and the corresponding easy-tear units on them can also be synchronously rolled up during the rolling process, so as to better realize the storage and transportation of the finished double-sided adhesive release film;

[0023] By setting the easy-tear unit, the easy-tear handle can be punched out of the double-sided release film to form an integrated structure with the double-sided release film, and the subsequent film tearing operation can be realized in conjunction with the pre-cut handle. At the same time, the tearing structure can be realized by directly attaching the easy-tear unit to the entire double-sided release film. The above two easy-tear units can evenly realize the smooth tearing of the double-sided release film without affecting the subsequent winding operation, so that it can be flexibly operated and used.

[0036] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0037] As described in the background art, the traditional double-sided adhesive design easily complicates the process and reduces the yield rate. At the same time, the provision of multiple protective films makes it inconvenient to remove them later.

[0038] In order to solve this technical problem, the utility model provides a TP double-sided adhesive protective film, which is applied to TP double-sided adhesive.

[0039] Specifically, please refer to Figure 1-8 TP double-sided adhesive protective film specifically includes:

[0040] It comprises a double-sided release film 1, which comprises:

[0041] An edge film 11 is formed at the edge of the double-sided release film 1;

[0042] The inner film 12 is located inside the edge film 11 and together with the edge film 11 constitutes the double-sided adhesive release film 1;

[0043] The easy-tear unit 2 is arranged on the double-sided release film 1 and is used for independently tearing off the double-sided release film 1 .

[0044] The TP double-sided adhesive protective film provided by the utility model combines multiple protective films into a single double-sided adhesive release film 1 on the basis of the traditional protective film, eliminating the problem of the traditional need to attach multiple protective films in sequence. At the same time, only with the design of a single easy-tear unit 2, the entire TP film can be torn off, which is convenient for the attachment and subsequent removal of the double-sided adhesive release film. At the same time, because the traditional single whole double-sided adhesive release film 1 is used as the TP protective film, multiple protective films can be relatively rolled up in the actual production process, and the corresponding easy-tear units thereon can also be synchronously rolled up during the rolling process, so as to better realize the storage and transportation of the finished double-sided adhesive release film.

[0045] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0046] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0047] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0048] Example 1

[0049] Please refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a TP double-sided adhesive protective film, the easy-tear unit 2 is an easy-tear handle 21, the easy-tear handle 21 has a handle body 210, a handle end 211 and a handle tail 212, the handle body 210, the handle end 211 and the handle tail 212 are connected in an end-to-end sequence to form the easy-tear handle 21, and both ends of one side of the handle end 211 have arc chamfers 213;

[0050] Both sides of the TP double-sided adhesive protective film easy-tear handle 21 have adhesive layers corresponding to the double-sided adhesive release film 1;

[0051] The double-sided release film 1 is provided with a groove body 22 adapted to the easy-tear handle 21, and the easy-tear handle 21 is integrally formed with the double-sided release film 1 through the groove body 22. The easy-tear unit 2 in this embodiment is formed by punching the edge of the double-sided release film 1 to form the easy-tear handle 21. Therefore, the easy-tear handle 21 and the double-sided release film 1 are an integrated structure before preparation, and there is no need to make and paste the handle separately like the traditional structure, thereby simplifying the production process. Moreover, the easy-tear handle 21 formed by punching has a better fit with the double-sided release film 1, and it can be better located on the same horizontal plane, thereby further improving the forming effect of the subsequent multiple double-sided release films 1 after rolling up;

[0052] As a further optimization of this embodiment: the outer circumference of the handle body 210 and the handle end 211 connected with the double-sided adhesive release film 1 are punched with a pre-cut line 214, such as Figure 5As shown, by setting the pre-breaking line 214, when the double-sided adhesive release film 1 is taken out, the tear-off handle 21 can be bent at the end of the handle end 211, so that the pre-breaking line 214 in the peripheral direction can be broken and tilted, and the tilted handle end 211 facilitates the operator to contact it, and further realizes the pulling out of the tear-off handle 21 as a whole to finally realize the removal of the double-sided adhesive release film 1;

[0053] As a further optimization of this embodiment: stress release holes 215 are punched at the connection between the two ends of the handle tail 212 away from one side of the handle body 210 and the double-sided adhesive release film 1, and the stress release hole 215 is also punched with pre-cut lines 220 along both sides of the handle tail 212;

[0054] like Figure 5 As shown, in the process of pulling out the tear handle 21 at the end of the handle end 211, the tail of the tear handle 21 is easily broken from the double-sided adhesive release film 1 on the contact surface during pulling out. In order to ensure that the tear handle 21 can remain intact during the pulling out process so as to facilitate the subsequent smooth removal of the double-sided adhesive release film 1, a stress release hole 215 and a second pre-breaking line 220 are provided. By providing the stress release hole 215, the stress during the pulling process can be dispersed, thereby effectively reducing the occurrence of tearing.

[0055] The first pre-broken line 214, the second pre-broken line 220 and the stress release hole 215 can all be realized by die cutting or laser cutting.

[0056] Example 2

[0057] The TP double-sided adhesive protective film provided in Example 1 is further optimized, specifically, as follows Figure 6 , Figure 7 and Figure 8 As shown, in this embodiment, the easy-tear unit 2 in the embodiment 1 is different. The easy-tear handle 21 in the easy-tear unit 2 in this embodiment is not punched out from the double-sided adhesive release film 1, but is made into a handle separately and attached to the double-sided adhesive release film 1, thereby retaining the integrity of the double-sided adhesive release film 1 to the greatest extent, making it more effective in the actual laminating and protection process, and further ensuring the stability of the adjacent double-sided adhesive release film 1 in the actual rolling process. The specific steps are as follows:

[0058] The connection between the handle body 210 and the handle end 211 is pre-pressed to form a pre-folding line 1 216, and the connection between the handle body 210 and the handle tail 212 is pre-pressed to form a pre-folding line 217. The handle body 210, the handle end 211 and the handle tail 212 in the easy-tear handle 21 are all located in the same plane as the double-sided adhesive release film 1, and the easy-tear unit 2 is arranged on the inner film 12, and the back of the handle tail 212 has an adhesive area 218;

[0059] Through the above structural design, the manufactured easy-tear handle 21 is adhered to the double-sided release film 1 through the adhesive area 218 thereon. In the actual process of tearing the double-sided release film 1, the handle end 211 is directly buckled to make one end of it tilted, so that the double-sided release film 1 can be separated from the adhesive. Compared with the embodiment 1, this embodiment retains the integrity of the double-sided release film 1, and also avoids the problem that the easy-tear handle 21 is broken and separated from the original double-sided release film 1 during the pulling process and cannot be taken out;

[0060] The above-mentioned embodiment 1 can make the easy-tear handle 21 punched out from the double-sided adhesive release film 1, so that it forms an integrated structure with the double-sided adhesive release film 1, and cooperate with the pre-cut handle to realize the subsequent film tearing operation. At the same time, in embodiment 2, the easy-tear unit 3 can be directly attached to the entire double-sided adhesive release film to realize the tearing structure. The above-mentioned two easy-tear units 2 can evenly realize the smooth tearing of the double-sided adhesive release film 1 without affecting the subsequent winding operation, so that it can be flexibly operated and used.

[0061] Example 3

[0062] The TP double-sided adhesive protective film provided in Example 2 is further optimized, such as Figure 6 , Figure 7 and Figure 8 As shown;

[0063] The handle tail 212 is adhered to the double-sided release film 1 through the adhesive area 218;

[0064] The handle tail 212 in the above-mentioned tear-away handle 21 can be pasted to the edges around the double-sided release film 1 through the pasting area 218, so as to ensure that the double-sided release film 1 can be smoothly separated from the TP and the film can be removed during the process of pulling the tear-away handle 21;

[0065] The surfaces of the handle body 210 and the handle end 211 are both smooth planes, and the connection between the handle body 210 and the handle tail 212 is pre-pressed to form a pre-folding line 219, such as Figure 7 As shown, by setting the pre-folding line three 219, before the handle end 211 is buckled, the pre-folding line three 219 makes it easier for one end of the handle end 211 to be tilted, which is beneficial to the subsequent buckling of the handle end 211;

[0066] like Figure 8 As shown, a plurality of double-sided release films 1 and the easy-tear units 2 thereon can be sequentially connected and rolled up to form a roll-shaped rolled state, thereby forming a stable storage state.

[0067] The use process of the TP double-sided adhesive protective film provided by the utility model is as follows: in Example 1, the double-sided adhesive release film 1 can be directly buckled and taken out by setting the easy-tear unit 2 punched out on the double-sided adhesive release film 1, and in Example 2, the tearing structure is realized by directly attaching the easy-tear unit 2 to the entire double-sided adhesive release film 1, and the double-sided adhesive release film 1 in Example 1 and Example 2 can both achieve full-surface attachment protection of TP through a single film, and at the same time, the easy-tear unit 2 can also achieve the effect of easy winding.
