Description

Technical Field

[0001] This utility model relates to the field of adhesive tape processing technology, specifically to an adhesive tape backing paper edge retention device. Background Technology

[0002] Adhesive tape is widely used in processes such as bonding, fixing, light shielding, and sealing of various components. For automated assembly, tape is typically supplied in roll form, consisting of an adhesive layer and a backing paper (release liner), with the adhesive layer and backing paper completely overlapping and bonded. However, in some applications, it's necessary to retain the backing paper after application to prevent damage to the adhesive layer during later assembly with other products. But due to the performance characteristics of the tape, the peel force between the adhesive layer and the backing paper is relatively high when the backing paper needs to be removed during subsequent assembly, making it difficult for workers to easily separate the backing paper from the adhesive layer, resulting in low work efficiency.

[0003] Therefore, it is necessary to improve the existing technology to overcome the aforementioned defects. Utility Model Content

[0021] To fully understand this application, detailed steps and structures will be presented in the following description to illustrate the technical solution of this application. Preferred embodiments of this application are described in detail below; however, in addition to these detailed descriptions, this application may have other implementation methods.

[0022] Please refer to Figures 1-3 As shown in the preferred embodiment of this application, a tape backing paper edge-retaining device is used to cut and separate the adhesive layer A1 in tape A to obtain tape A with a backing paper A2 edge, so that after the tape A is applied, the adhesive layer A1 and the backing paper A2 can be easily separated by the worker. The tape backing paper edge-retaining device includes a frame 1, a mounting frame 2 mounted on the frame 1, a feeding assembly 3 mounted on the mounting frame 2, a cutting assembly 4, a recycling assembly 5, and a conveying assembly 6. The feeding assembly 3 is used to wind tape A, which includes a completely overlapping adhesive layer A1 and a backing paper A2. The cutting assembly 4 is located on one side of the feeding assembly 3 and includes a transition roller 41 and a cutting element 42. Tape A is wound around the transition roller 41 with the backing paper A2 attached to it. The cutting element 42 is used to cut the adhesive layer A1 into a first adhesive strip A11 and a second adhesive strip A12 along the longitudinal direction of tape A, so that the first adhesive strip A11 is separated from the backing paper A2. The recycling assembly 5 includes a first recycling tray 51 and a second recycling tray 52 disposed on one side of the cutting assembly 4. A recycling reel 51 is used to wind the first adhesive strip A11, and a second recycling reel 52 is used to wind the base paper A2 and the second adhesive strip A12. The conveying assembly 6 includes a first conveyor 61, a second conveyor 62 and a third conveyor 63 located between the feeding assembly 3 and the cutting assembly 4. The first conveyor 61 is used to convey the tape A, the second conveyor 62 is used to provide tension to the tape A wound with the transition wheel 41 so that the cutting member 42 cuts the adhesive layer A1 into the first adhesive strip A11 and the second adhesive strip A12, and the third conveyor 63 is used to convey the second adhesive strip A12 and the base paper A2.

[0023] Understandably, by setting up the cutting element 42, the transition wheel 41, the first recycling tray 51, and the second recycling tray 52, the cutting element 42 can cut the completely overlapping adhesive layer A1 of the tape A into a first adhesive strip A11 and a second adhesive strip A12, so that the first adhesive strip A11 is separated from the backing paper A2 to form the target tape A (tape A with the backing paper left on the edge). The first recycling tray 51 can roll up and collect the cut first adhesive strip A11, and the second recycling tray 52 can roll up the cut target tape A for subsequent tape A application work, thereby making it easier for workers to easily separate the backing paper A2 of the target tape A from the second adhesive strip A12 and improving work efficiency.

[0024] Understandably, by separately setting up a first conveyor 61, a second conveyor 62, and a third conveyor 63, the first conveyor 61 is used to provide initial traction to ensure that the tape A is smoothly discharged from the unloading assembly 3 and to prevent loosening; the second conveyor 62 is used to form controllable tension at the cutting point to ensure that the cut is straight and the width is stable; the third conveyor 63 is used to pull the target tape to the second recycling tray 52 to avoid a large amount of target tape accumulating or slipping in front of the second recycling tray 52.

[0025] Further, refer to Figure 3 and Figure 4 As shown, the cutting assembly 4 includes a mounting bracket 2 mounted on a mounting frame 2. The mounting bracket 2 is provided with a mounting groove 21 along the width direction of the tape A. The cutting piece 42 is detachably connected along the mounting groove 21 to change the width of the first adhesive strip A11 and the second adhesive strip A12 to be compatible with target tapes A of different widths. No structural replacement is required, which meets the diverse needs of customers and is more efficient.

[0026] Furthermore, the cutting assembly 4 also includes a sliding member 43 mounted on the mounting bracket 2. The cutting member 42 is disposed on the sliding member 43. Under the action of external force, the sliding member 43 can drive the cutting member 42 to move up and down to get closer to or away from the tape A on the transition wheel 41. This allows the position of the cutting member 42 to be adjusted according to tape A of different thicknesses, and also allows the tape A to be threaded and the cutting member 42 to be replaced without stopping the machine.

[0027] Further, refer to Figure 5 As shown, both the first recycling reel 51 and the second recycling reel 52 include a reel 511, a first disc 512 and a second disc 513 that are sequentially movably mounted on the reel 511, and an adjustable winding space 514 is formed between the first disc 512 and the second disc 513, thereby accommodating different widths of target tape A and first adhesive strip A11 and improving the neatness of winding.

[0028] Furthermore, the device also includes a drive assembly (not shown), which includes a first drive member, a second drive member, and a third drive member. The first drive member is used to drive the first conveyor 61 to rotate to generate conveying force, ensuring stable tension in the unwinding section and preventing loosening or breakage. The second drive member is used to drive the second conveyor 62 and the transition wheel 41 to rotate, providing precise synchronous speed for the cutting point and avoiding width errors caused by speed differences. The third drive member is used to drive the third conveyor 63 to rotate, thereby making the tension of the target tape A independent of the front section and preventing tension coupling from causing tape A to elongate or shrink.

[0029] Furthermore, the drive assembly also includes a fourth drive member and a first magnetic powder clutch connecting the fourth drive member to the first recycling disc 51, a fifth drive member and a second magnetic powder clutch connecting the fifth drive member to the second recycling disc 52. In this embodiment, the purpose of providing the first and second magnetic powder clutches is that when the feeding end (the feeding assembly 3 or the target tape A after being cut by the cutting assembly 4) pauses or decelerates, the magnetic powder clutches enter a "slipping" state, that is, the drive member continues to rotate but the output shaft is stationary. At this time, the recycling disc stops collecting material due to the lack of traction. When the feeding end resumes feeding, the magnetic powder clutches immediately output torque synchronously, and the recycling disc continues to collect material. This ensures that the entire production line will not stop when changing tape rolls or when the equipment is temporarily stopped, which can save the losses from starting and stopping, and also prevent tape A from being stretched or broken due to sudden stops.

[0030] Furthermore, the equipment also includes a buffer assembly, comprising a first buffer assembly 7 located between the feeding assembly 3 and the cutting assembly 4, and a second buffer assembly 8 located between the first recycling tray 51 and the second recycling tray 52. ​​The first buffer assembly 7 stores tape A to provide storage length for the cutting assembly 4. When the tape A on the feeding assembly 3 is exhausted, the tape A stored in the first buffer assembly 7 can continue to supply tape A to the cutting assembly 4, thus achieving uninterrupted cutting. The second buffer assembly 8 stores the second adhesive strip A12 and the backing paper A2. The purpose of this arrangement is that, since the thickness of the first adhesive strip A11 recycled by the first recycling tray 51 is less than the thickness of the second adhesive strip A12 and the backing paper A2 recycled by the second recycling tray 52, the second recycling tray 52 fills up faster and is replaced more frequently. The second buffer assembly 8 allows for the temporary storage of the target tape A cut by the cutting assembly 4 without stopping the machine when replacing the second recycling tray 52, ensuring continuous production without line interruption.

[0031] Furthermore, both the first buffer assembly 7 and the second buffer assembly 8 include a slide rail 71 arranged along the height direction, a slider 72 arranged on the slide rail 71, a first buffer wheel 73 arranged above the slide rail 71, and two second buffer wheels 74 located on the slider 72. The tape A is wound around the second buffer wheel 74, the first buffer wheel 73, and the second buffer wheel 74 in sequence.

[0032] Understandably, by setting the slide rail 71 in the height direction, the slider 72 can drive the wound tape A to move upward, so as to store as much tape A as possible in the smallest space. Moreover, this setting method utilizes gravity to automatically restore the state, without the need for additional elastic elements, and the structure is simple.

[0033] Understandably, by setting a first buffer wheel 73 above the slide rail 71 and two second buffer wheels 74 on the slider 72, and then winding the tape A around one of the second buffer wheels 74, the first buffer wheel 73, and the other second buffer wheel 74 in sequence, this three-segment S-shaped winding further increases the storage capacity of the tape A, and the tension change is evenly distributed, making the tape A less prone to wrinkling.

[0034] Furthermore, the first buffer assembly 7 / second buffer assembly 8 also includes a first detection element 75 and a second detection element 76 located at the upper and lower ends of the slide rail 71. The first detection element 75 and the second detection element 76 are used to detect the upper limit and lower limit of the slider 72, respectively. That is, when the upper limit is detected, the tape A in the buffer assembly is used up, and when the lower limit is detected, the tape A in the buffer assembly is full, so as to facilitate the staff to handle the situation accordingly.

[0035] Furthermore, the device also includes a separating wheel 9 disposed between the cutting assembly 4 and the first recycling tray 51. After the tape A is cut by the cutting component 42 and wound around the separating wheel 9, the first adhesive strip A11 is wound by the first recycling tray 51, and the second adhesive strip A12 and the backing paper A2 are wound by the second recycling tray 52.

[0036] Understandably, by providing a sharp-angle wrapping by the separation wheel 9, the first adhesive strip A11 is forcibly separated from the second adhesive strip A12 and the backing paper A2 at a small radius to overcome the re-adhesion force. In summary, the working process of the tape backing paper edge-retaining device shown in this utility model is as follows: the feeding assembly releases the tape and, under the action of the first conveyor, transmits it to the cutting assembly. The cutting component of the cutting assembly is positioned to cut the adhesive layer of the tape, so that the adhesive layer is cut into the first adhesive strip and the second adhesive strip along the longitudinal direction. The first adhesive strip is collected by the first recycling disc after passing through the separation wheel. The second adhesive strip and the backing paper with the edge retained are conveyed by the second conveyor to the second buffer assembly and, under the action of the third conveyor, are wound and collected by the second recycling disc.

[0037] The above is only one specific implementation of this application, and any other improvements made based on the concept of this application shall be considered within the scope of protection of this application.
