Description

Technical Field

[0001] This application relates to the field of tape preparation, and more particularly to an anti-spillage tape and tape rolls using the same. Background Technology

[0002] Adhesive tape, also known as adhesive strip, tape, or adhesive paper, is a strip-shaped, adhesive man-made product that can be adhered to the surface of some items. It can be used to connect two different items or as a kind of barrier or protection. Adhesive tape is generally composed of two parts: a substrate and an adhesive.

[0003] In the actual manufacturing process of adhesive tape, the adhesive is generally applied to the substrate by coating equipment. For example, Chinese patent document CN222724724U discloses a coating mechanism for adhesive tape, which also includes a collection structure on the side of the tape. This collection structure can collect the material overflowing during the coating process for reuse. In other words, during the coating process, the collection structure collects the overflowing material. Chinese patent document CN222042057U discloses a tape production winding device with a cleaning function. The continuous increase of adhesive on the surface of the protective sleeve causes the adhesive to flow from the scraper to the inner wall of the collection tank, allowing the collection tank to collect the adhesive in a timely and effective manner. This device scrapes and collects excess adhesive carried on the surface of the tape roller, reducing the amount of adhesive overflowing from both sides of the tape after it is rolled into a roll. This increases the functionality of the device; similarly, during the coating process, the collection tank also collects the adhesive in a timely and effective manner.

[0004] In the aforementioned patent documents, the essence of both technical solutions is to collect the adhesive that overflows from the substrate, especially from the sides, during the coating process. However, neither solution solves the problem of adhesive overflow from the sides of the tape during the tape winding process after coating. Figure 6 As shown, the coated tape is wound onto the roller, shaft, or other connecting device shown in the figure. When the outer tape is wound, it will squeeze the inner tape (the outer tape will exert a radial force on the inner tape). Under the pressure of the outer tape, the adhesive on the inner tape substrate will overflow from both sides of the tape. The overflowed adhesive will stick to the sides of the tape roll, sticking adjacent tapes together, which is not conducive to the normal unfolding of the tape. The adhesive may even stick to the roller or shaft of the tape roll or other connecting device, hindering the normal rotation of the roller or shaft.

[0005] In addition, ultraviolet radiation and temperature are also important factors affecting the problem of adhesive overflow on both sides of the tape during winding. Specifically, Chinese patent document CN11741770 A discloses a BOPP tape with ultra-high adhesion and high heat resistance, its preparation method, and preparation system. This document mentions the addition of a UV curing system, allowing the edges of the tape in contact with the outside environment to be rapidly cured by ultraviolet light after use. The purpose of this design is to ensure that the adhesive inside the tape does not melt and overflow from the edges under high-temperature conditions, thus guaranteeing the tape's performance and cleanliness. The newly added metal oxide coating forms an effective barrier on the BOPP film, preventing ultraviolet light from penetrating into the tape's interior, thereby ensuring that the adhesive inside the tape does not cure accidentally. This is particularly important for tape applications that may be exposed to sunlight, ensuring the stability and effectiveness of the tape during use.

[0006] The essence of the technical solution in Chinese patent document CN11741770 A is to configure a special chemical coating to prevent the tape from overflowing on the sides under the influence of high temperature and ultraviolet light. However, this solution still does not solve the problem of tape overflowing on both sides when the tape is wound up. The special chemical coating of the inner tape is also subjected to the squeezing force of the outer tape. Under this squeezing force, the special chemical coating cannot prevent the tape from overflowing on both sides when it is wound up. Summary of the Invention

[0007] The purpose of this application is to provide an anti-side spillage tape and a tape roll using the same, so as to solve the problem of adhesive spillage on both sides when the tape is wound into a roll in the prior art.

[0008] An anti-spillage tape includes a tape body and an adhesive body. The adhesive body is disposed in the middle of the tape body along the length direction of the tape body, and there is a gap between the side of the adhesive body and the side of the tape body on the same side.

[0009] Its beneficial effects are: when the tape is rolled up, the outer tape will squeeze the inner tape, and the adhesive that overflows from the inner tape due to the squeeze will overflow into the blank gap, instead of overflowing to the sides of the tape, thereby preventing the rolled tape from sticking together, thus facilitating the normal use of the tape.

[0010] In some implementations, the gap on one side of the colloid is the same width as the gap on the other side of the colloid.

[0011] Its beneficial effects are: the gaps on both sides of the colloid have the same width, so the two gaps can accommodate the same amount of overflow, and the same gaps facilitate cutting and processing.

[0012] In some embodiments, the colloid is disposed in the middle of the belt along the length of the belt, and there is a blank interval between any two adjacent segments of colloid.

[0013] Its beneficial effect is that when using tape, the tape is adhered to the surface to be used, and when the tape is separated from the tape, the relevant force can be applied to the blank gaps, making it easier for the tape to be separated from the tape.

[0014] In some implementations, the width of any blank space is equal.

[0015] A method for preparing anti-spillage tape, comprising:

[0016] A coating device is used to coat the substrate and form a coating area, and the width of the coating area is equal to the width of the colloid; a first blank area is provided on both sides of the coating area on the substrate, and the width of the first blank area is equal to the width of the blank gap.

[0017] A roll of tape using anti-spill tape, which can be rolled onto a fixing device.

[0018] In some implementations, the fixing device is a roller.

[0019] In some implementations, the fixing device is a shaft.

[0020] A method for preparing anti-spillage tape, comprising:

[0021] The substrate is coated with several coating areas of equal width by a coating equipment, and the width of the coating area is equal to the width of the adhesive; a second blank area is provided between any two adjacent coating areas; a third blank area is provided outside the outermost coating area on the substrate, and the width of the third blank area is equal to the width of the blank gap; the second blank area is cut using a cutting equipment to finally obtain the anti-side spill tape.

[0022] In some implementations, the cutting device can act at the middle position along the length of the second blank area, dividing the second blank area into two blank gaps of unequal width.

[0023] In some embodiments, the cutting device can act on the center of the second blank area along its length direction to divide the second blank area into equal parts along its length direction; half the width of the second blank area is equal to the width of the blank gap.

[0033] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only some, not all, of the embodiments of this application, and are used merely to explain this application and are not intended to limit it. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

In addition, the terms "first," "second," "upper-level," "lower-level," "main," and "secondary," etc., are used for descriptive purposes only and can be simply used to more clearly distinguish different components, and should not be construed as indicating or implying relative importance.

[0035] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, an integral connection, a mechanical connection, an electrical connection, a direct connection, or an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0036] like Figures 1-3 As shown,

[0037] An anti-spillage tape includes a tape body 1 and an adhesive body 2. The adhesive body 2 is disposed in the middle of the tape body 1 along the length direction of the tape body 1, and there is a gap 3 between the side of the adhesive body 2 and the side of the tape body 1 on the same side.

[0038] The colloid 2 mentioned here is generally of the type of dot adhesive, flat adhesive, double-sided adhesive, etc. The specific color and shape of the tape 1 and colloid 2 are arbitrary and can be selected according to the specific application.

[0039] Its beneficial effect is that when the tape is rolled up, such as Figure 6 As shown, the outer tape will squeeze the inner tape. The adhesive 2 that overflows from the inner tape due to the squeeze will overflow into the blank gap 3, but will not overflow to the sides of the tape. This can prevent the rolled tape from sticking together, thus facilitating the normal use of the tape.

[0040] Preferably, the width of the blank gap 3 on one side of the colloid 2 is equal to the width of the blank gap 3 on the other side of the colloid 2.

[0041] Its beneficial effects are: the blank gaps 3 on both sides of the colloid 2 have the same width, so the two blank gaps 3 can accommodate the same amount of overflow glue, and the same blank gaps 3 can facilitate cutting and processing.

[0042] like Figure 2 As shown,

[0043] Preferably, the colloid 2 is disposed in the middle of the belt 1 along the length of the belt, and a blank interval 4 is provided between any two adjacent segments of colloid.

[0044] Its beneficial effect is that when using adhesive tape, the tape is adhered to the surface being used. When separating the adhesive 2 from the tape 1, the relevant force can act at the blank interval 4, facilitating the separation of the adhesive 2 from the tape 1. For example, in Figure 2 In the diagram, when the tape is pasted on a surface such as paper, after a certain length of tape is pasted, the adhesive 2 needs to be separated from the tape body 1. The user only needs to apply a pulling force to the blank interval 4 to easily separate the adhesive 2 from the tape body 1.

[0045] Preferably, the width of any blank interval 4 is equal.

[0046] like Figure 6 As shown,

[0047] A roll of tape using anti-spill tape, which can be rolled onto a fixing device.

[0048] Preferably, the fixing device is a roller.

[0049] Preferably, the fixing device is a shaft.

[0050] like Figure 4 As shown in the first embodiment,

[0051] A method for preparing anti-spillage tape, comprising:

[0052] The substrate 01 is coated using a coating device to form a coating area 011, and the width of the coating area 011 is equal to the width of the colloid 2; a first blank area 012 is provided on both sides of the coating area 011 on the substrate 01, and the width of the first blank area 012 is equal to the width of the blank gap 3.

[0053] This method is applicable to situations where only one tape is prepared from a single substrate 01. The coating equipment can be a common coating roller for coating, or it can be a device with a colloid collection function similar to the schemes in Chinese patent documents CN222724724U and CN222042057U. For its specific structure, please refer to the above documents or other relevant documents, so it will not be described in detail here.

[0054] like Figure 5 As shown, in the second embodiment,

[0055] A method for preparing anti-spillage tape, comprising:

[0056] The substrate 01 is coated with several coating areas 011 of equal width by a coating equipment, and the width of the coating area 011 is equal to the width of the colloid 2; a second blank area 013 is provided between any two adjacent coating areas 011; a third blank area 014 is provided outside the outermost coating area 011 on the substrate 01, and the width of the third blank area 014 is equal to the width of the blank gap 3; a cutting equipment cuts the second blank area 013, and the cutting equipment acts on the center of the second blank area 013 along its length direction to divide the second blank area 013 equally along its length direction; the second blank area 013 is cut by the cutting equipment to finally obtain the anti-side spill tape.

[0057] Preferably, the cutting device can act on the middle position of the second blank area 013 along its length to divide the second blank area 013 into two blank gaps 3 with unequal widths.

[0058] Preferably, the cutting device can act on the center of the second blank area 013 along its length direction to divide the second blank area 013 into equal parts along its length direction; half the width of the second blank area 013 is equal to the width of the blank gap 3.

[0059] This method is applicable to the situation where multiple tapes are prepared from a single substrate 01. The coating equipment can have common coating rollers for coating; the specific number of coating rollers can be one or more. For example, one coating roller can be used to coat the coating area 011 on the substrate 01 sequentially, or multiple coating rollers can be used to coat simultaneously. The specific coating process is selected according to the specific tape production situation.

[0060] The coating equipment can also be a device with a colloid 2 collection function similar to the schemes in Chinese patent documents CN222724724U and CN222042057U. For its specific structure, please refer to the above documents or other relevant documents, so it will not be described in detail here.

[0061] Cutting equipment generally includes slitting machines or other equipment with similar functions. The cutting equipment is aligned... Figure 5 Cut along the cutting baseline to cut a whole piece of substrate into several pieces of tape.

[0062] It should be noted that the width of the blank gap 3 is preferably 0.1mm to 2.0mm.

[0063] For example, when the width of the tape is 6mm, the width of the adhesive 2 is preferably 5mm, and the width of the blank gap 3 is preferably 0.5mm.

[0064] The above descriptions are merely some embodiments of this application, used only to illustrate the technical solutions of this application, and not to limit it. It should be understood that those skilled in the art can make improvements or substitutions based on the above descriptions without departing from the inventive concept of this application, and all such improvements and substitutions should fall within the protection scope of the appended claims. In this case, all details can be replaced with equivalent elements, and the materials, shapes, and sizes can also be arbitrary.
