[0023] The dial plate 201 is fixedly connected with a handle 202 via bolts.

[0024] The preparation device also includes a base 501, the upper end of the base 501 is rotatably connected to a tube threading platform 401 through a bearing, the base 501 is fixedly connected to a first motor 405 through bolts, the tube threading platform 401 is fixedly connected to the output shaft of the first motor 405, a material guide plate 403 is welded to the upper end of the tube threading platform 401, a plurality of partitions 404 are welded to the upper end of the material guide plate 403, a plurality of limiting ridges 406 are fixedly connected inside the material guide plate 403, and the positions of the plurality of partitions 404 and the plurality of limiting ridges 406 correspond one to one respectively.

[0025] A raising pad 402 is bonded inside the tube-threading platform 401 , and the raising pad 402 is attached to the inner wall of the tube-threading platform 401 .

[0026] The base 501 is fixedly connected to the second motor 502 by bolts, the output shaft of the second motor 502 is fixedly connected to the insertion rod 504, the fixing sleeve 504 is provided with a positioning hole 505, the winding drum 101 is fixedly connected to the fixing sleeve 103 by bolts, and the fixing sleeve 103 is provided with a matching hole 104.

[0027] One of the partitions 404 is rotatably connected to a swing rod 601 via an axis, and a pressure roller 602 is rotatably connected to the swing rod 601 via an axis. A plurality of sponge strips are bonded to the surface of the pressure roller 602 , and a torsion spring 603 is installed at the rotation connection between the swing rod 601 and the partition 404 .

[0028] A blocking bar 604 is welded to one of the partitions 404 .

[0029] The pressure roller 602 is fixedly connected with a friction wheel 605, and the insertion rod 504 is fixedly connected with a matching wheel 503, and the matching wheel 503 is gradually concave from both sides to the middle.

[0030] A process for preparing an adhesive tape using an adhesive tape preparation device, the process comprising the following steps:

[0031] Step 1: First, the staff will place the cut paper tubes between the multiple partitions 404, and use the inclined surface of the guide plate 403 to make the paper tubes roll onto the tube threading platform 401;

[0032] Step 2: Use the winding drum 101 to pass through multiple paper rolls, and the sliding plate 201 causes multiple positioning members 303 to slide outward at the same time to position the paper rolls;

[0033] Step 3: Use the positioning pin to fix the take-up drum 101 and the insertion rod 504, and control the second motor 502 to drive the insertion rod 504 to drive the take-up drum 101 to rotate and reel the tape;

[0034] Step 4: The pressure roller 602 comes into contact with the surface of the take-up drum 101 to compact the tape and clean the surface of the tape;

[0035] Step 5: Disassemble the take-up drum 101 and take out the tape roll.

[0036] The raw materials of the adhesive tape prepared by the adhesive tape preparation device include: a base material and a rubber base, wherein the base material is a polyethylene film, and the rubber base includes 80-100 parts of natural rubber, 60-75 parts of terpene resin, 3-5 parts of polybutene and 1-2 parts of antioxidant.

[0037] See also Figure 3-9 ,

[0038] When using the processing device, the staff first places the cut paper tubes between multiple partitions 404 respectively, and the paper tubes are in a state where their own curved surfaces are in contact with the guide plate 403. The inclined surface of the guide plate 403 is used to allow the paper tubes to automatically roll onto the tube threading platform 401. At this time, the staff places the winding roller 101 on the tube platform 401, and then pushes the winding roller 101 to the right. The lifting pad 402 serves to raise the winding roller 101, which can prevent the winding roller 101 from contacting the bottom of the tube threading platform 401, thereby facilitating the passage of multiple paper tubes.

[0039] See also Figure 1-6 ,

[0040] After the winding drum 101 passes through the paper roll, the staff manually turns the handle 202, and the handle 202 is convenient for manually controlling the dial plate 201 to rotate. Since the two baffles 302 are symmetrically arranged with the axis of the winding drum 101, one side of the positioning member 303 is arc-shaped and a slot 301 is arranged in the middle, when the dial plate 201 rotates clockwise, the two ends of the dial plate 201 are respectively in contact with the arc surface of the positioning member 303, so that the multiple positioning members 303 slide outward at the same time, and the multiple springs 203 are forced to generate When the paddle plate 201 is compressed and rotated to a horizontal state, the two ends of the paddle plate 201 can be respectively inserted into the slots 301 of the positioning members 303 on both sides, so that the protruding positioning members 303 remain fixed and prevent the positioning members 303 from automatically returning to their original position under the action of the springs 203. The two baffles 302 play a role in blocking the paddle plate 201 to prevent the paddle plate 201 from excessively rotating and disengaging from the positioning members 303. When the paddle plate 201 rotates in the opposite direction, the positioning members 303 are automatically returned to their original position under the action of the multiple springs 203.

[0041] See also Figure 3 and Figure 7 ,

[0042] Since the other side of the positioning member 303 is provided with positioning grooves on both sides which are gradually recessed toward the middle, when the positioning member 303 is extended, the two positioning members 303 can cooperate to fix the paper tube, so that the paper tube is sleeved on the two positioning members 303, and the positioning grooves on the two positioning members 303 play a role in positioning the paper tube. As the two positioning members 303 are extended, the paper tube can gradually move into the middle positioning groove, so that multiple paper tubes are respectively located in the positioning grooves of multiple positioning members 303, ensuring that the spacing between each paper tube is equal, and then the tape is fixed to each paper tube respectively, and the winding of the tape is achieved by controlling the rotation of the winding drum 101. In the process of winding the tape, external force can be prevented from causing the paper tube to deviate on the winding drum 101, thereby avoiding the phenomenon of winding deviation and further reducing the risk of loss.

[0043] See also Figure 7 ,

[0044] When the tape needs to be rolled up, the staff places the winding drum 101 on the lifting pad 402, pushes the winding drum 101 so that the fixing sleeve 103 thereon is sleeved on the insertion rod 504, and aligns the positioning hole 505 and the matching hole 104, and inserts the positioning pin into the positioning hole 505 and the matching hole 104 to fix the winding drum 101 and the insertion rod 504. At this time, the insertion rod 504 is driven to rotate by controlling the second motor 502, and the insertion rod 504 drives the winding drum 101 to rotate to roll up the tape. The lifting pad 402 can ensure the height of the winding drum 101 so that the fixing sleeve 103 is neatly sleeved on the insertion rod 504 without the need for further adjustment, thereby further improving convenience.

[0045] See also Figure 7-8 ,

[0046] After the winding drum 101 and the insertion rod 504 are fixed, the guide plate 403 is driven to rotate by controlling the first motor 405. At this time, the tube threading platform 401 drives the pressure roller 602 to move downward, and the pressure roller 602 comes into contact with the surface of the winding drum 101. The pressure roller 602 compacts the tape to ensure the adhesion of the tape. At the same time, the sponge strip on the pressure roller 602 cleans the surface of the tape to remove dust and impurities on the tape to prevent dust from affecting the viscosity of the tape. A torsion spring 603 is installed at the rotating connection with the partition 404, so that when the pressure roller 602 contacts the winding drum 101, the torsion spring 603 is stressed, thereby realizing the flexible squeezing effect of the pressure roller 602 on the winding drum 101, and the baffle 604 serves to limit the pressure roller 602. After the torsion spring 603 is stressed, the swing arm 601 is blocked by the baffle 604, which can prevent the pressure roller 602 from shaking during rotation and causing it to separate from the winding drum 101, thereby avoiding affecting the squeezing effect of the pressure roller 602 on the tape.

[0047] See also Figure 7-8 ,

[0048] When the guide plate 403 rotates, it can drive the friction wheel 605 to move downward, and finally the friction wheel 605 comes into contact with the mating wheel 503. Since the mating wheel 503 is gradually recessed from both sides to the middle, the mating wheel 503 can come into close contact with the friction wheel 605 to avoid slipping. Therefore, when the mating wheel 503 rotates, it can drive the friction wheel 605 to rotate, thereby driving the pressure roller 602 to rotate, thereby realizing the function of pressing the tape and cleaning the dust and impurities on its surface.
