[0044] S52. When an abnormal depression or bulge is detected at a certain position during winding, the position can be marked with pigment using the winding device.

[0046] The plastic granules in S1 are made of polypropylene granules.

[0047] The cooling device in S3 is an air pipe connected to an air pump that can blow out cold air.

[0048] The S3 includes multiple cooling devices.

[0049] like Figure 4-6 and Figure 9 As shown:

[0050] The winding device includes a fixed plate 101 and a fixed frame 406. A rotating rod 102 is rotatably connected to the fixed plate 101. A circular piece is detachably connected to the front side of the fixed plate 101 by bolts. A sliding strip 103 is connected to the fixed plate 101. A moving block 201 is slidably connected to the sliding strip 103. A first compression spring is fixed between the sliding strip 103 and the moving block 201. A rotating sleeve 202 is rotatably connected to the moving block 201. A contact roller 203 is connected to the rotating sleeve 202. A detection block 301 is slidably connected to the contact roller 203. An imprint cotton block 303 is fixedly connected to the detection block 301. A transverse rod 404 is slidably connected to the fixed frame 406. A slide frame 401 is slidably connected to the transverse rod 404. A slitting blade 403 is rotatably connected to the slide frame 401. A toggle part 402 is connected to the detection block 301, and a protrusion 304 is fixedly connected to it. The toggle part 402 can move the protrusion 304. The moving block 201 can move horizontally along the left and right directions of the fixed plate 101. A second compression spring is fixedly connected between the slide 401 and the transverse rod 404. A first motor that can drive the rotating rod 102 to rotate is fixedly connected to the fixed plate 101. A second motor that can drive the rotating sleeve 202 to rotate is fixedly connected to the moving block 201. A third motor is fixedly connected to the fixed frame 406. A first lead screw is fixedly connected to the output shaft of the third motor. The first lead screw is threadedly connected to the transverse rod 404. A fourth motor that can drive the slitting blade 403 to rotate is fixedly connected to the slide 401. A displacement sensor is fixedly connected to the sliding bar 103. The moving end of the displacement sensor is fixedly connected to the moving block 201.

[0051] A reel capable of winding is fitted onto the rotating rod 102, and then a circular disc is placed over the rotating rod 102, thereby fixing the reel in place with the fixing plate 101. One end of the adhesive tape to be wound is then adhered to the reel. The rotating rod 102 is then continuously rotated on the fixing plate 101, gradually causing the reel to rotate and the adhesive tape to be wound and adhered to the reel, thus completing the automatic winding process. During this process, as the number of layers of adhesive tape wound on the reel gradually increases... This allows the contact roller 203 to be gradually pushed by the tape substrate with an increasing number of winding layers, causing the moving block 201 to slide on the sliding bar 103 against the elastic force of the first compression spring. This causes the contact roller 203 to drive the moving block 201 to slide to the left on the fixed plate 101. The winding thickness can be detected in real time by detecting the distance the moving block 201 slides to the left. When the winding thickness reaches the target requirement, the rotation of the operating rod 102 can be stopped in time to stop the winding work. Then the tape substrate is cut to complete the winding work.

[0052] After the winding operation is completed, the slide 401 can be slid on the transverse bar 404, causing the slitting blade 403 to rotate continuously on the slide 401. This causes the rotating slitting blade 403 to gradually approach the wound tape substrate, while simultaneously causing the rotating sleeve 202 to rotate continuously on the moving block 201, thereby slitting the wound tape substrate. After one slitting operation, the slide 401 is slid back to its original position, and then the transverse bar 404 slides a suitable distance on the fixed frame 406, moving to the position where the next operation is needed. The process is repeated at the next cutting position to complete multiple cutting operations on the tape substrate, thereby forming multiple individual tape rolls after winding. At the same time, the sliding distance of the contact roller 203 can be detected to simultaneously determine the sliding distance of the subsequent carriage 401. This ensures that when the slitting blade 403 is used for slitting, it can slide to the exact cutting position on the tape substrate, thus ensuring a stable automatic slitting effect for production requirements with different winding thicknesses.

[0053] During the winding process, the transverse bar 404 can be periodically slid from front to back on the fixed frame 406, causing the actuating part 402 to move the detection block 301 from the front to the moving block 201 on the cooperating rod 302. This allows the detection block 301 to gradually contact different positions on the tape substrate, enabling it to detect contact at different locations. Therefore, when abnormal depressions or bulges appear on the tape substrate during winding, the detection block 301 will cause the moving block 201 to move when it passes that position. When the sliding bar 103 slides abnormally due to the elastic force of the first compression spring, the displacement sensor can receive the signal in time. At this time, the rotating sleeve 202 can be operated to rotate clockwise on the moving block 201, so that the detection block 301 rotates synchronously with the contact roller 203, and the marking cotton block 303 on the upper side of the detection block 301 comes into contact with the surface of the tape substrate, thereby marking the abnormal protrusion or depression position, so that the staff can quickly find the deviation position, and thus provide convenience for subsequent manual inspection or remedial work.

[0054] The second compression spring between the carriage 401 and the transverse bar 404 allows the carriage 401 to slide synchronously on the transverse bar 404 during the winding process, thereby ensuring that the actuating part 402 is always in the sliding position that can actuate the detection block 301, and ensuring the normal operation of the transmission effect of the subsequent equipment.

[0055] like Figure 5-6 As shown:

[0056] Two imprinted cotton blocks 303 are symmetrically arranged, and the two imprinted cotton blocks 303 are impregnated with different colors of pigment;

[0057] After the winding operation is completed using this equipment, the horizontal bar 404 can be operated to slide multiple times on the fixed frame 406 according to the cutting position of the slitting blade 403. The rotating sleeve 202 can be operated periodically to rotate counterclockwise on the moving block 201, thereby causing the marking cotton block 303 on the lower side of the detection block 301 to contact the tape substrate multiple times. This allows the marking cotton block 303 on the lower side to leave multiple reference pigment marks on the tape substrate according to the control program. At this time, the operator can accurately understand the multiple cutting positions of the slitting blade 403 under this control program based on the multiple reference pigment marks. This allows the operator to confirm the control program before cutting to ensure that the current control program meets the target production requirements and further guarantee the finished product effect.

[0058] like Figure 5-6 As shown:

[0059] The device also includes a mating rod 302 fixedly connected to the protrusion 304, the actuating part 402 rotatably connected to the slide 401, the contact roller 203 rotatably connected to the rotating sleeve 202, a torsion spring fixedly connected between the contact roller 203 and the rotating sleeve 202, an electromagnetic block that can attract the contact roller 203 fixedly connected to the O2, and a fourth motor that can drive the actuating part 402 to rotate fixedly connected to the slide 401;

[0060] When it is necessary to use the upper of the two marking cotton blocks 303 to mark the deviation position, so as to ensure that the subsequent staff can quickly mark the deviation position, if the power source driving the rotating sleeve 202 to rotate fails and thus cannot mark normally, the magnetic force of the electromagnetic block can be removed. Then, the actuating part 402 is operated to rotate clockwise on the slide 401, which causes the actuating part 402 to move the cooperating rod 302, thereby causing the contact roller 203 to rotate on the rotating sleeve 202. This allows the upper of the two marking cotton blocks 303 to still complete the marking effect on the deviation position, ensuring that the marking operation is carried out stably.

[0061] like Figure 5 , Figure 8 As shown:

[0062] The device also includes a push rod 204 fixedly connected to the rotating sleeve 202, an auxiliary plate 407 fixedly connected to the fixed frame 406, a sliding bar 103 slidably connected to the fixed plate 101, and a third compression spring fixedly connected between the sliding bar 103 and the fixed plate 101.

[0063] When a slitting operation is required, the rotating sleeve 202 can be rotated on the moving block 201, which causes the push rod 204 to push the sliding bar 103 to slide downward on the fixed plate 101 through the auxiliary plate 407, thereby causing the contact roller 203 to gradually move away from the front of the slitting blade 403, thus facilitating the subsequent slitting operation using the slitting blade 403.

[0064] During the downward movement of the sliding bar 103, the attraction force of the electromagnetic block is removed, so that when the mating rod 302 contacts the actuating part 402, the contact roller 203 can spontaneously rotate on the rotating sleeve 202, thereby facilitating the detection block 301 to pass through the position of the actuating part 402 and avoiding interference.

[0065] like Figure 7 As shown:

[0066] The device also includes a pressure rod 405 slidably connected to a transverse rod 404, a fifth motor fixedly connected to the transverse rod 404, a second lead screw fixedly connected to the output shaft of the fifth motor, and the second lead screw threadedly connected to the pressure rod 405.

[0067] When it is necessary to operate the slide 401 to slide, the pressure rod 405 can be operated to slide on the transverse rod 404, so that the pressure rod 405 gradually pushes the slide 401 to overcome the elastic force of the second pressure spring and slide, thereby driving the slitting blade 403 to complete the slitting operation.
