Description

Technical Field

[0001] This utility model relates to the field of release equipment technology, and in particular to a release mechanism for release paper of soft materials. Background Technology

[0002] In the manufacturing process, soft materials with a certain degree of elasticity and softness, such as sponge pads and soft rubber pads, are often used. These soft materials are usually applied to shock absorption, protection, or reinforcement of products. To fix the soft materials in a predetermined position, adhesive methods are usually used; thus, a layer of release paper is often attached to the surface of the soft material to protect the underlying adhesive layer.

[0003] In practice, the release paper needs to be peeled off to expose the adhesive layer in order to bond and fix the material. Currently, this peeling process mainly relies on manual labor, but there is a significant efficiency bottleneck: the peeling speed is slow, and it often requires multiple operations to successfully peel off the release paper completely. This not only affects the overall production efficiency, but also increases the uncertainty and labor costs in the operation process. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a mechanism for peeling release paper from soft materials, including a conveying device, an unwinding shaft, a waste roller, a peeling plate, and a peeling roller. The conveying device carries and continuously conveys the soft material. A roll of adhesive tape is mounted on the unwinding shaft, and the waste roller is used to collect the used adhesive tape, achieving automatic rewinding of the waste material. The peeling plate has a peeling end at its front end, and the peeling roller is arranged above the peeling end. Its function is to guide the soft material with the release paper already peeled, allowing it to continue moving smoothly in the predetermined direction of the conveying device. Between the unwinding shaft and the peeling end, the adhesive tape forms a first path, which is located above the conveying device. After the adhesive tape passes around the peeling end, it enters a second path, which is tangential to the peeling roller. An acute angle is formed between the first and second paths. As the adhesive tape passes around the peeling end and enters the second path, the release paper is effectively peeled off.

[0005] According to some embodiments of this utility model, a first drive motor is also provided, which is connected to the peeling roller via belt drive. The first drive motor drives the peeling roller to rotate, thereby applying a guiding force to the soft material.

[0006] Specifically, a first pulley is mounted on the first drive motor and the stripping roller, and power is transmitted between the two pulleys through the first belt.

[0007] According to some embodiments of the present invention, a belt drive wheel is also provided, which is located at the end of the second path; a third path is formed between the belt drive wheel and the waste wheel, through which the belt enters the waste wheel; an idler wheel is provided above the belt drive wheel, and the belt passes through the gap between the idler wheel and the belt drive wheel to enhance the control of the belt.

[0008] According to some embodiments of this utility model, the second drive motor is responsible for simultaneously driving the belt drive wheel and the waste wheel. The output shaft of the second drive motor is equipped with a double-groove pulley, and the belt drive wheel and the waste wheel are each equipped with a second pulley. The power connection is realized through two second belts.

[0009] According to some embodiments of this utility model, an upper pressure roller is also included, which is located below the unwinding shaft (200) and can apply a certain pressure to the tape. The upper pressure roller is connected to a cylinder via a lever plate. When the cylinder is activated, it pulls the lever plate, causing the upper pressure roller to press against the tape, thereby improving the reliability of initial adhesion.

[0010] According to some embodiments of this utility model, all the above-mentioned components are mounted on a unified mounting main board. This main board not only rotatably mounts the unwinding shaft, waste roller, stripping roller, lever plate, and upper pressure roller, but also fixes the stripping plate, ensuring the stability and coordinated operation of the overall structure.

[0011] This utility model has at least the following beneficial effects: 1. In the actual peeling operation, the tape is released from the tape roll and initially travels along the first path. At this time, the soft material to be peeled off is transported by the conveyor to a position below the first path, where the tape adheres to the release paper.

[0012] 2. The soft material continues to be conveyed forward to the peeling plate area. When its front end aligns vertically with the peeling end, the peeling action officially begins. As the conveyor belt bypasses the peeling end and enters the second path, it begins to move diagonally backward, gradually pulling up the release paper and completing the peeling process. This design significantly improves the production efficiency of the peeling operation while greatly reducing operational uncertainties and reliance on manual labor, facilitating automated production.

[0013] 3. Due to the inherent softness of the material, it is prone to deformation during the peeling process, posing a risk of it wrapping around the peeling end with the tape. To prevent this, the peeling roller maintains contact with the peeled soft material, applying a guiding force to ensure the material continues to move along the conveying direction, thus guaranteeing smooth peeling of the release paper and further optimizing the peeling effect.

[0014] Additional aspects and advantages of this invention will be set forth in part in the description on the second page, and in part will be obvious from the description on the second page, or may be learned by practice of this invention. Attached Figure Description

[0015] The first and / or additional aspects and advantages of this utility model will become apparent and readily understood from the description of the embodiments taken in conjunction with the second page of the drawings, wherein: Figure 1 This is a schematic diagram of the overall front view of an embodiment of the present utility model; Figure 2 This is a schematic diagram of the tape movement direction according to an embodiment of the present invention; Figure 3 This is a schematic rear view of an embodiment of the present utility model. Detailed Implementation

[0016] The second page describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described in the second page with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0017] In the description of this utility model, the meaning of "first" is that "greater than", "less than", "exceeding", etc., are understood to exclude the stated number. If "first" and "second" are used in the description, they are only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features indicated, or implicitly indicating the order of the technical features indicated.

[0018] Reference Figure 1 , 2 As shown, a mechanism for peeling release paper from soft materials includes a conveying device 100, an unwinding shaft 200, a waste roller 300, a peeling plate 400, and a peeling roller 500. The conveying device 100 is used to carry and continuously convey soft materials, the unwinding shaft 200 is equipped with a roll of tape, and the waste roller 300 is used to recycle the used tape, thereby realizing automatic winding of waste materials.

[0019] The front end of the peeling plate 400 is provided with a peeling end 410, and the peeling roller 500 is arranged above the peeling end 410. Its function is to guide the soft material that has been peeled off the release paper so that it can continue to move smoothly in the predetermined direction of the conveying device 100.

[0020] Between the unwinding shaft 200 and the peeling end 410, the tape forms a first path 101, which is located above the conveying device 100. After passing around the peeling end 410, the tape enters a second path 102, which is tangential to the peeling roller 500. An angle 103 is formed between the first path 101 and the second path 102. The angle 103 is acute. As the tape passes around the peeling end 410 and enters the second path 102, it effectively peels off the release paper.

[0021] In the actual peeling operation, the tape is released from the tape roll and first travels along the first path 101. At this time, the soft material to be peeled off is transported by the conveyor 100 to a position below the first path 101, where the tape adheres to the release paper.

[0022] The soft material continues to be conveyed forward to the peeling plate area 400. When its front end aligns vertically with the peeling end 410, the peeling action officially begins. As the conveyor belt passes around the peeling end 410 and enters the second path 102, the conveyor belt begins to move diagonally backward, thereby gradually pulling up the release paper and completing the peeling process. This design significantly improves the production efficiency of the peeling operation, while greatly reducing operational uncertainties and reliance on manual labor, which is conducive to achieving automated production.

[0023] However, due to the softness of the material itself, it is prone to deformation during the peeling process. When the tape with release paper attached moves obliquely backward, the soft material may be pulled up along with the tape, risking it to bypass the peeling end 410. To prevent this, a peeling roller 500 is provided. When the tape with release paper attached begins to move obliquely backward after passing the peeling end 410, the material and release paper are in a preliminary peeling state. The tape with release paper attached enters the second path 102 tangentially to the peeling roller 500, while the material continues to be conveyed forward and enters below the peeling roller 500, so that the material and the peeling roller 500 are also in a tangential state. This allows the peeling roller 500 to separate the release paper from the material. At the same time, the peeling roller 500 maintains contact with the peeled soft material and applies a guiding force to ensure that the material can continue to move along the conveying direction, thereby ensuring the smooth peeling of the release paper and further optimizing the peeling effect.

[0024] Before actual operation, preparatory work is required, including correctly installing the tape roll onto the unwinding shaft 200, pulling the tape to pass through the first path 101 and the second path 102 in sequence, and finally fixing it onto the waste wheel 300.

[0025] Reference Figure 1 , 3 As shown, a first drive motor 600 is also provided, which is connected to the peeling roller 500 via belt drive. The first drive motor 600 drives the peeling roller 500 to rotate, so that it applies guiding force to the soft material.

[0026] Specifically, a first pulley 201 is mounted on the first drive motor 600 and the stripping roller 500, and power is transmitted between the two pulleys through the first belt 202.

[0027] Reference Figures 1 to 3As shown, to further optimize the belt drive, a belt drive wheel 700 is also provided, which is located at the end of the second path 102; a third path 104 is formed between the belt drive wheel 700 and the waste wheel 300, through which the belt enters the waste wheel 300. An idler wheel 800 is provided above the belt drive wheel 700, and the belt passes through the gap between the idler wheel 800 and the belt drive wheel 700 to enhance the control of the belt.

[0028] The second drive motor 900 is responsible for simultaneously driving the belt drive wheel 700 and the waste wheel 300. The output shaft of the second drive motor 900 is equipped with a double groove pulley 203, and the belt drive wheel 700 and the waste wheel 300 are each equipped with a second pulley 204. The power connection is achieved through two second belts 205.

[0029] Reference Figure 1 , 3 As shown, to enhance the adhesion between the tape and the release paper, the mechanism also includes an upper pressure roller 1000, which is located below the unwinding shaft 200 and can apply a certain pressure to the tape.

[0030] The upper pressure roller 1000 is connected to the cylinder 3000 via the lever plate 2000. The center of the lever plate 2000 is equipped with a rotating shaft 2100. The cylinder 3000 is used to pull the lever plate 2000, causing the lever plate 2000 to rotate around the rotating shaft 2100.

[0031] When cylinder 3000 is activated, it pulls lever plate 2000, causing upper pressure roller 1000 to press against the tape, making the tape and release paper come into close contact, thereby improving the reliability of initial adhesion.

[0032] The cylinder 3000 is electrically connected to the photoelectric sensor 5000, which faces the conveyor 100. Soft material is conveyed by the conveyor 100 to the area below the photoelectric sensor 5000, triggering the photoelectric sensor 5000 to send a signal to the cylinder 3000. The cylinder 3000 then operates, and the upper pressure roller 1000 presses down, applying pressure to the belt and the material to make them adhere.

[0033] All of the above components are mounted on a unified mounting main board 4000, which not only rotatably mounts the unwinding shaft 200, waste roller 300, stripping roller 500, lever plate 2000, and upper pressure roller 1000, but also fixes the stripping plate 400, ensuring the stability and coordinated operation of the overall structure.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
