Description

Technical Field

[0001] This utility model belongs to the field of tape processing and relates to a stripping module for double-layer tape. Background Technology

[0002] In the field of adhesive tape processing, when double-layer adhesive tape is cut in half, the face material and adhesive layer are severed, while the backing paper remains intact. After this, the face material needs to be accurately and completely separated from the backing paper to meet the requirements of subsequent processing or use.

[0003] Existing peeling modules rely solely on a retraction mechanism to separate the backing paper and the face paper. Due to the lack of more effective separation methods and auxiliary mechanisms, incomplete separation is likely to occur during the separation process, meaning that the face paper and the backing paper are still partially adhered, resulting in the face paper failing to meet quality standards after separation. Utility Model Content

[0004] The purpose of this utility model is to provide a peeling module that improves the stability of separating the backing paper and the face material by improving the structure, thereby improving the separation quality of the face material.

[0014] As a further improvement of one embodiment of this utility model, the retraction mechanism includes a first linear slide rail disposed on the top of the side plate and a second linear slide rail disposed on the bottom plate. The first and second linear slide rails are parallel and horizontally distributed. One side of the second suction cup is slidably disposed on the first linear slide rail via a slider, and the other side is fixedly connected to the supporting side plate. The supporting side plate is slidably disposed on the second linear slide rail via a slider, so that the second suction cup can move linearly along the first and second linear slide rails.

[0015] A second motor is provided on the side plate, and the second motor is fixed to the side plate by a motor mount. A first synchronous pulley is provided on the output shaft of the second motor.

[0017] As a further improvement of one embodiment of the present invention, the second suction cup is provided with at least two sets of adjustment grooves, and the second suction cup is provided with a limiting plate that limits the position of the double-layer tape. The limiting plate has a limiting groove for the double-layer tape to be embedded, and the limiting plate is provided with a locking member. The locking member passes through the adjustment groove and locks the limiting plate onto the second suction cup.

[0018] As a further improvement of one embodiment of the present invention, the tensioning assembly includes a tensioning frame, the transmission roller is pivotally mounted on the tensioning frame, and one end of the transmission roller is exposed and connected to the first drive assembly; both ends of the tensioning roller are pivotally mounted on the first frame, the tensioning frame is provided with a horizontal slide groove for the first frame to be embedded in, and the tensioning frame is provided with a manual adjustment assembly for driving the first frame to move in the horizontal slide groove.

[0045] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0046] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0047] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model. Example

[0048] See Figures 1-5 As shown, a stripping module includes a frame 1, which serves as the main support for the entire stripping module, undertaking the installation and load-bearing tasks of the entire module. In this embodiment, the frame 1 consists of a base plate 11 and side plates 12, which can be fixed by welding or bolting. To enhance structural strength, a reinforcing block is provided between the base plate 11 and the side plates 12. The reinforcing block can be a triangular metal block, which is fixed at the connection point by welding or riveting.

[0049] The feed tray 2 and take-up tray 3 are set on one side of the frame 1. The feed tray 2 is used to store the double-layer tape to be processed. Its tray body is designed to be rotatable to facilitate the tape to be unwound smoothly. The take-up tray 3 is used to collect the separated bottom paper. It also has a rotating function to ensure that the bottom paper can be neatly wound.

[0050] The feed roller 4 is pivotally mounted on the frame 1 via a bearing, located between the pressure plate assembly 5 and the feed plate 2. The surface of the feed roller 4 can be specially treated, such as by adding anti-slip textures, to increase the friction between it and the double-layer conveyor belt, ensuring that the conveyor belt can be smoothly and accurately fed to the pressure plate assembly 5.

[0051] The pressure plate assembly 5 includes a first suction cup 51 and a pressure plate 53 driven by a first cylinder 52. The first suction cup 51 is fixedly mounted on the frame 1 via a connector. The suction holes on the surface of the first suction cup 51 are evenly distributed, and their number and size can be designed according to actual needs to ensure uniform and sufficient suction force, thereby adsorbing and fixing the double-layer adhesive tape through vacuum adsorption. The first cylinder 52 is located directly above the first suction cup 51, and its piston rod is fixedly connected to the pressure plate 53. When the first cylinder 52 is working, the piston rod drives the pressure plate 53 to move downward, pressing the double-layer adhesive tape tightly onto the first suction cup 51. At this time, the first suction cup 51 is in a vacuum state, adsorbing and fixing the bottom paper of the double-layer adhesive tape, providing a stable fixing base for subsequent peeling operations.

[0052] Furthermore, a crossbeam 54 is provided above the first suction cup 51. Both ends of the crossbeam 54 are securely fixed to the first suction cup 51 by support columns. The support columns, crossbeam 54, and first suction cup 51 can be fixed by welding or threaded connection. A first cylinder 52 is mounted on the crossbeam 54 to provide downward pressing power to the pressure plate 53. Guide sleeves are provided on the crossbeam 54 located on both sides of the first cylinder 52. Each guide sleeve contains a guide post, with a clearance fit between the guide post and the guide sleeve. The lower ends of the guide posts are fixed to the pressure plate 53 by welding or snap-fit, ensuring smooth downward pressing of the pressure plate 53.

[0053] The double-layer adhesive tape on the pressure plate assembly 5 extends to the retraction mechanism 6, which separates the backing paper and the face paper. The retraction mechanism 6 includes a second suction cup 61 that can move horizontally on the frame 1. The second suction cup 61 is mounted on the frame via a linear guide rail and slider mechanism, enabling horizontal sliding. Multiple suction holes are evenly distributed on its surface; a vacuum adsorption device generates negative pressure to adsorb and fix the backing paper. One side of the second suction cup 61 is designed with an edge, which can be polished to make its surface smooth and prevent scratching the backing paper.

[0054] As the second suction cup 61 moves backward, the pressure plate assembly 5 firmly secures the double-layer tape through the vacuum adsorption of the first suction cup 51 and the pressing action of the pressure plate 53. Simultaneously, the receiving tray 3 begins to rotate and recycle the base paper, bringing it to a taut state. At this point, the base paper and the face material separate at the corners of the second suction cup 61, and the face material is stably and smoothly separated from the base paper thanks to the guiding action of the corners of the second suction cup 61.

[0055] The frame 1 is also equipped with a tensioning assembly 7 and a return roller 8. The return roller 8 is located between the tensioning assembly 7 and the retraction mechanism 6, and is mounted on the frame via bearings. It can rotate freely and is used to smoothly convey the bottom paper separated by the retraction mechanism 6 to the tensioning assembly 7. The tensioning assembly 7 includes a drive roller 71 and a tension roller 72. The tension roller 72 can be adjusted to clamp the bottom paper between the drive roller 71 and the tension roller 72, ensuring the tension of the bottom paper during the conveying process. Both the drive roller 71 and the take-up tray 3 are synchronously driven by a first drive assembly, such as a motor, via belt or chain transmission, ensuring the coordination of bottom paper recovery and tension.

[0056] Specifically, the retraction mechanism 6 includes a first linear slide rail 62 disposed on the top of the side plate 12 and a second linear slide rail 63 disposed on the bottom plate 11. The first linear slide rail 62 and the second linear slide rail 63 are parallel and horizontally distributed to ensure the accuracy of the movement direction of the second suction cup 61.

[0057] The second suction cup 61 is slidably mounted on the first linear slide rail 62 on one side by a slider, and fixedly connected to the support side plate 64 on the other side. The support side plate 64 is in turn slidably mounted on the second linear slide rail 63 by a slider. This structure allows the second suction cup 61 to move stably in a straight line along the two linear slide rails, thereby realizing the backward movement of the bottom paper.

[0058] A second motor 65 is mounted on the side plate 12 and fixed to it via a motor mount. A first synchronous pulley 66 is mounted on the output shaft of the second motor 65, and a second synchronous pulley 67 is mounted on the side plate 12 via a bearing pivot. A first synchronous belt 68 is wound between the first and second synchronous pulleys 66 and 67. A clamping assembly 69 is fixedly mounted on the first synchronous belt 68, with one end of the clamping assembly 69 fixedly connected to a second suction cup 61. When the second motor 65 operates, it drives the first synchronous pulley 66 to rotate, thereby causing the first synchronous belt 68 to move. The movement of the first synchronous belt 68 then moves the second suction cup 61, completing the retraction mechanism's operation.

[0059] Furthermore, the clamping assembly 69 consists of a clamping plate 691, a fixing plate 692, and a connecting plate 693. The clamping plate 691 has toothed grooves adapted to the first synchronous belt 68. The shape and size of the toothed grooves match the tooth profile of the first synchronous belt 68, ensuring tight meshing and preventing slippage. The fixing plate 692 is placed above the first synchronous belt 68 and is securely fixed to the clamping plate 691 by bolts, achieving a reliable connection between the clamping plate 691 and the fixing plate 692. The upper end of the connecting plate 693 is fixed to the second suction cup 61 by welding or bolts, and the lower end is also fixed to the fixing plate 692 by welding or bolts, thereby achieving a stable connection between the second suction cup 61 and the clamping assembly 69.

[0060] In this embodiment, in order to improve the adaptability of the second suction cup 61 to double-layer tapes of different specifications, at least two sets of adjustment grooves 613 are provided on the second suction cup 61. These adjustment grooves 613 can be designed as long strips, parallel and evenly distributed on the surface of the second suction cup 61.

[0061] The second suction cup 61 is also equipped with a limiting plate 611, which has a limiting groove for embedding double-layer adhesive tape. The depth and width of the limiting groove can be designed according to the thickness and width of common double-layer adhesive tapes. The limiting plate 611 is equipped with a locking element 612, which can be a combination of bolt and nut. It passes through the adjustment groove 613 and locks the limiting plate 611 onto the second suction cup 61. By adjusting the position of the limiting plate 611 in the adjustment groove 613, it can accommodate double-layer adhesive tapes of different widths, ensuring stable operation.

[0062] In this embodiment, the tensioning component 7 plays a crucial role in maintaining the tightness of the bottom paper. For example... Figure 5 The component includes a tensioning frame 73, and a transmission roller 71 is pivotally mounted on the tensioning frame 73 via a bearing, with one end exposed to connect to the first drive assembly so as to receive drive power to achieve rotation.

[0063] Both ends of the tension roller 72 are also mounted on the first frame 74 via bearing pivots. The tension frame 73 has a horizontal groove for the first frame 74 to be inserted into, and the first frame 74 can move horizontally within the groove. To achieve the displacement adjustment of the first frame 74, the tension frame 73 is provided with a manual adjustment component.

[0064] Specifically, the manual adjustment assembly includes an adjustment shaft 751, whose two ends are pivotally mounted on the tensioning frame 73 via bearings. One end of the adjustment shaft 751 is exposed outside the tensioning frame 73 and has a handle 75 mounted thereon. A limit shaft is provided on the handle 75, and the tensioning frame 73 has a corresponding arc-shaped groove 76 for inserting the limit shaft. A bearing 77 is also mounted on the limit shaft. A locking member 78 is provided between the first frame 74 and the support plate 79. One end of the locking member 78 is exposed and abuts against the bearing 77. A spring is fitted onto the locking member 78, with one end abutting against the support plate 79 and the other end abutting against the locking member 78. When the operator turns the handle 75, the adjusting shaft rotates, causing the limiting shaft to move within the arc groove 76, which in turn pushes the locking member 78 to move against the spring force, causing the first frame 74 to shift within the horizontal slide groove, adjusting the position of the tension roller 72, thereby changing the clamping degree of the transmission roller 71 and the tension roller 72 on the bottom paper, and thus adjusting the tightness of the bottom paper.

[0065] In this embodiment, the first drive assembly provides synchronous drive power to the transmission roller 71 and the receiving tray 3. Specifically, this assembly includes a first motor 91 mounted on the frame 1, which can be securely fixed by means of bolts or other methods. A third synchronous pulley 92 is mounted on the output shaft of the first motor 91, and a fourth synchronous pulley 93 and a first belt pulley 94 are provided at one end of the transmission roller 71. A second synchronous belt is wound between the third synchronous pulley 92 and the fourth synchronous pulley 93. When the first motor 91 operates, it drives the transmission roller 71 to rotate through the second synchronous belt.

[0066] Meanwhile, a second pulley 95 is installed on the rotating shaft of the receiving tray 3, and the first pulley 94 and the second pulley 95 are connected by a transmission belt 96. In this way, the power of the first motor 91 can be transmitted to the transmission roller 71 and the receiving tray 3 simultaneously, ensuring that the two operate synchronously and achieving stable recycling and tension adjustment of the bottom paper.

[0067] The stripping module provided by this utility model is a component of the tape processing equipment. It is closely integrated with other parts of the tape processing equipment and shares the control system, power supply system, air supply system, vacuum system, etc. of the tape processing equipment. Through a unified interface and operation instructions, the coordinated operation of each link is realized. The power supply system provides stable power to the device to ensure continuous operation of the equipment; the vacuum system meets the needs of the adsorption stage inside the device.

[0068] During the separation of the face material and the backing paper, the pressure plate assembly 5 uses the vacuum suction force generated by the first suction cup on it and the pressing action of the pressure plate to firmly fix the double-layer tape, preventing the double-layer tape from moving backward synchronously during the backward movement of the backward mechanism 6, thereby ensuring the accuracy of the separation action.

[0069] During the separation stage of the face paper and the backing paper, the first motor 91 and the second motor 65 operate at the same speed. The first motor 91 provides power to the drive roller 71 and the take-up tray 3, while the second motor 65 drives the second suction cup 61 to move backward via a synchronous belt. The two motors work together to keep the backing paper taut throughout the separation process. At this time, relying on the corner of the second suction cup 61, the backing paper and the face paper are misaligned at the corner, allowing the face paper to separate stably and smoothly from the backing paper.
