A strip structure to prevent product displacement on release film strip

Abstract

This utility model relates to a release film tape, specifically a tape structure to prevent product displacement on the release film tape. Support strips are spaced apart along the width direction on the surface of the release film tape, extending along the forward direction of the tape. The product is placed in a strip-shaped groove formed between adjacent support strips. The height of the support strips is not less than the height of the product. When the release film tape is in a wound state, the support strips support the product between two adjacent turns of the release film tape, and there is a gap between the top surface of the product and the adjacent release film tape in the inner turn. Compared with the prior art, this utility model solves the problem that existing technologies cannot prevent small-sized products with a certain height from shifting or falling off during the winding process due to external forces. This solution improves the tape structure, achieving support during the winding process and preventing the force applied during winding from directly acting on the product, thus avoiding product displacement and falling off caused by external forces.

Description

Technical Field

[0001] This utility model relates to a release film strip, specifically to a strip structure that prevents products from shifting on the release film strip. Background Technology

[0002] Currently, some small items (especially small horizontal items) require winding and securing with release film during production, with the products arranged in an array with certain intervals on the release film. However, for products with a certain height, such as small items with a height of 1-2mm, the force generated during winding and the friction between the coils will be fully applied to each product when it is attached to the release film. Since the force on the product is usually not completely perpendicular to the product surface, the product may shift or even fall off the release film under external force.

[0003] The prior art CN112126359A discloses a packaging structure for adhesive tape that prevents overflow and displacement due to compression. This structure includes a pair of support strips on the bottom release film used to support the adhesive tape product, preventing overflow during winding. However, the adhesive tape itself is adhered to the bottom release film at multiple points, and the top release film further positions and limits the tape. Therefore, during transportation and winding on the release film, and under external vibration conditions, the adhesive tape itself maintains good contact and fixation, preventing displacement and detachment. Thus, the problem of displacement and detachment does not exist.

[0004] In contrast, smaller products are smaller in size, resulting in a smaller contact area with the release film strip. Furthermore, considering cost and downstream process integration, no additional release film is added on top of the product to limit its overall position. This means that each smaller product still needs to be distributed discretely on the release film strip. Moreover, for products with a film layer on top (such as release film, handle film, etc.), applying another layer of release film for overall product limiting can easily lead to the removal of the top film layer along with the release film, causing product defects and increasing the scrap rate. Therefore, it is clear that for products with a top film layer, the existing technology cannot be used to achieve limiting. Furthermore, existing solutions only use support strips on both sides of the release film. Experiments have shown that this cannot completely overcome the displacement problem of small parts located in the middle of the release film. While small parts near the sides have some restraining effect, those in the middle still shift and detach, further affecting the restraint of smaller parts on their sides. Therefore, it is necessary to propose an appropriate tape structure to assist in the winding process of small parts, preventing displacement and detachment during winding and under external vibration. Utility Model Content

[0005] The purpose of this invention is to provide a material strip structure that prevents product displacement on the release film strip, thereby addressing the problem in the prior art where small-sized products with a certain height cannot be prevented from shifting or falling off during the winding process due to external forces. This solution improves the material strip structure, providing support during the winding process and preventing the forces exerted on the product directly during winding, thus avoiding product displacement and detachment caused by external forces.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A strip structure for preventing product displacement on a release film strip, wherein at least two support strips are spaced apart along the width direction on the surface of the release film strip, the support strips extend along the forward direction of the release film strip, and the product is placed in the strip-shaped groove formed between adjacent support strips.

[0008] The width direction is the direction perpendicular to the forward direction of the release film strip within the plane containing the release film strip;

[0009] The height of the support strip is not less than the height of the product, wherein the height of the support strip is the distance from the top surface of the support strip to the surface of the release film strip, and the height of the product is the distance from the top surface of the product to the surface of the release film strip.

[0010] When the release film strip is in a wound state, the support strip is supported between two adjacent turns of the release film strip, and there is a gap between the top surface of the product and the adjacent release film strip located in the inner ring.

[0011] Preferably, when there are two support bars, the support bars are respectively disposed on both sides of the product, and the support bars are disposed close to the product;

[0012] When there are at least three support strips, the support strips include side support strips and middle support strips; there are two side support strips, which are respectively disposed on the sides of the release film strip in the width direction, and the middle support strip is disposed on the release film strip between the two side support strips.

[0013] It is important to note that the support strips should be positioned as close to the product as possible without affecting its placement. This ensures that the support strips can effectively support the release film strip on the product during the winding process, preventing the inner ring of the release film strip from contacting the upper surface of the product and causing friction that could lead to product displacement or detachment.

[0014] Preferably, the intermediate support strips are arranged at equal intervals along the width direction of the release film strip.

[0015] Preferably, the support strips are evenly spaced along the width direction of the release film strip.

[0016] Preferably, the surface of the release film strip is provided with five support strips spaced apart along the width direction, and four strip-shaped grooves are formed between the five support strips. Products are placed at intervals in each strip-shaped groove along the forward direction of the release film strip.

[0017] Preferably, the hardness of the support strip is expressed as 40 degrees on the Shore A scale.

[0018] Preferably, when the product is placed in the strip-shaped groove, the support strip is set separately from the product, so that a gap is formed between the support strip and the product.

[0019] Preferably, the height of the product is 1-2 mm, and the support strip is made of foam with a thickness of at least 2 mm.

[0020] Preferably, the product includes a handle film, a product body, and an adhesive layer;

[0021] The adhesive layer is applied to the top and bottom surfaces of the product body;

[0022] The handle film is bonded to the top surface of the product body through an adhesive layer;

[0023] When the product is placed in the strip-shaped trough, the bottom surface of the product body is in contact with the release film strip through the adhesive layer.

[0024] Preferably, the main body of the product is a tubular structure with a central through-hole, and the height of the main body of the product is 1.5mm; the adhesive layer is double-sided adhesive, and the thickness of the adhesive layer is 0.05mm.

[0025] The working principle of this utility model is as follows:

[0026] In the release film strip structure, support strips with a height no lower than the product and a certain degree of rigidity are set on the release film strip. Thus, after the release film strip is wound up, the support strips provide structural support between adjacent turns, and the top surface of the product no longer contacts the release film strip located on the inner turn. The force is entirely located on the support strips, which avoids the product from shifting or falling off due to external forces. This improves the problem of the product falling off the release film strip and not being in its original position after vibration.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] In the material strip structure of this solution, a support strip with a height no lower than the product and a certain degree of rigidity is set on the release film material strip. Thus, after the release film material strip supporting the product is wound up, the support strip serves as a structural support between the loops. The top surface of the product no longer comes into contact with the release film material strip located in the inner loop, so that the force is only applied to the support strip, avoiding the phenomenon of product displacement or falling off due to external forces.

[0034] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0035] This application proposes a solution to the displacement and detachment problems that occur when small (small size, especially small horizontal size) products 2 are wound up by release film tape 1.

[0036] like Figure 1 As shown, this is a typical structural form of product 2, which consists of three parts: the product body 22, the handle film 21, and the adhesive layer 23.

[0037] The main body 22 is a 1.5mm thick PC block with a through-hole in the middle, making the main body 22 a tubular structure. Specifically, in the following description, it will be referred to as... Figure 1 The square tube structure shown is used as an example for explanation.

[0038] On the top surface of the main body 22 of the product ( Figure 1 The upper surface and the bottom surface in the direction shown) Figure 1 An adhesive layer 23 is attached to each of the lower surfaces in the direction shown, and the adhesive layer 23 is made of double-sided adhesive with a thickness of 0.5 mm.

[0039] On the top surface of the product body 22, a handle film 21 is bonded to it via an upper adhesive layer 23. The handle film 21 has the same width as the product body 22 and a longer length than the product body 22. The handle film 21 also has square openings that match the through structure in the product body 22. The handle film 21 extends from one side of the product body 22.

[0040] In the prior art, when winding up product 2, each product 2 is directly arranged in an array with a certain interval on the release film tape 1, such as... Figure 2 As shown, the strip is then wound up by the core 4 mounted on the winding device. In the resulting product 2 roll, the coils are supported by the product 2 itself. The forces exerted after winding, such as pressure from outside the roll and friction from inside the roll, will act directly on the product 2, causing it to shift and fall off.

[0041] In response, this solution proposes a strip structure that can prevent product 2 from shifting on release film strip 1.

[0042] Example 1

[0043] A material strip structure to prevent product 2 from shifting on release film strip 1, wherein at least two support strips 3 are spaced apart along the width direction on the surface of release film strip 1, the support strips 3 extend along the forward direction of release film strip 1, and product 2 is placed in the strip-shaped groove formed between adjacent support strips 3.

[0044] The width direction is the direction perpendicular to the forward direction of the release film strip 1 within the plane containing the release film strip 1;

[0045] The height of the support strip 3 is not less than the height of the product 2, wherein the height of the support strip 3 is the distance from the top surface of the support strip 3 to the surface of the release film strip 1, and the height of the product 2 is the distance from the top surface of the product 2 to the surface of the release film strip 1.

[0046] When the release film strip 1 is in the wound state, the support strip 3 is supported between two adjacent turns of the release film strip 1, and there is a gap between the top surface of the product 2 and the adjacent release film strip 1 located in the inner ring.

[0047] More specifically, in this embodiment:

[0048] Please refer to this. Figure 3 , 4 The structure shown.

[0049] The material strip structure further adds a support strip 3 to the release film material strip 1. The support strip 3 extends along the forward direction of the release film material strip 1, and the height of the support strip 3 should be set not less than the height of the product 2.

[0050] At least two support strips 3 are provided on the release film strip 1:

[0051] When only two support bars 3 are provided, the two support bars 3 can also be provided on both sides of the product 2 respectively, and the two support bars 3 are provided close to the product 2 so that the support bars 3 can replace the product 2 to realize the structural support between the rings after winding.

[0052] When there are three or more support bars 3, these support bars 3 can be specifically divided into side support bars 3 and middle support bars 3. At this time, the side support bars 3 are located on both sides of the release film strip 1 in the width direction, and the middle support bars 3 are located on the release film strip 1 between the two side support bars 3.

[0053] Between two adjacent support strips 3, the support strips 3 and the release film strip 1 together form a strip-shaped trough for placing the product 2. The product 2 is arranged at intervals in each strip-shaped trough along the forward direction of the release film strip 1, and the product 2 does not contact the support strips 3 (a gap is left between the product 2 and the support strips 3) so that the downstream process steps can process, transfer and other operations on the product 2 in the original way.

[0054] All support strips 3 can be arranged at equal intervals on the release film strip 1; or, only the middle support strip 3 can be arranged at equal intervals on the release film strip 1, and the distance between the middle support strip 3 and the side support strip 3 can be different from the distance between the middle support strip 3.

[0055] The support strip 3 is made of strip-shaped foam with a hardness of 40 degrees (Shore A hardness). Corresponding to the product 2 with a thickness of about 1.5mm mentioned above, the height can be about 2mm. Specifically, it is preferable to use foam with a square cross-section and a size of 2*2mm.

[0056] In the above, the height of support strip 3 refers to the distance between the top surface of support strip 3 and the surface of release film strip 1, the height of product 2 refers to the distance between the top surface of product 2 and the surface of release film strip 1, the forward direction of release film strip 1 refers to the winding direction of release film strip 1, and the width direction of release film strip 1 refers to the direction perpendicular to the forward direction of release film strip 1 in the same plane as the forward direction of release film strip 1.

[0057] Example 2

[0058] In this embodiment, as Figure 3 , 4As shown, five support strips 3 are provided on the release film strip 1. Two of them are side support strips 3, one on the left and one on the right, located on the sides of the release film strip 1 in the width direction. The remaining three are intermediate support strips 3, which are equally spaced and axially symmetrically arranged on the release film strip 1 between the side support strips 3. The distance from the outermost intermediate support strip 3 to the side support strip 3 is not equal to the distance between the intermediate support strips 3. The rest of the structure is the same as the strip structure shown in Example 1.

[0059] Using the material strip structure proposed in this solution, after product 2 is wound up from the core 4 along with the release film material strip 1, the adjacent loops are structurally supported by the support strip 3, and there is a certain gap between product 2 and the adjacent inner loop release film material strip 1, thereby avoiding the direct action of friction on product 2 when external force is applied, and further preventing product 2 from shifting and falling off on the release film material strip 1.

[0060] The above description of the embodiments is provided to enable those skilled in the art to understand and use the utility model. It will be apparent to those skilled in the art that various modifications can be easily made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, the present utility model is not limited to the above embodiments, and any improvements and modifications made by those skilled in the art based on the disclosure of the present utility model without departing from its scope should be within the protection scope of the present utility model.
