[0085] Back to Figure 6 , according to the utility model embodiments, the glue scraping mechanism 3 includes a second rotating shaft 301, a swing arm 302 and a scraper 303. The utility model swing arm 302 is of U-shaped structure, as shown in Figure 6 .

[0086] The second rotating shaft 301 is rotatably installed on the rack 1, and the swing arm 302 is fixed on the second rotating shaft 301.

[0087] Specifically, the second bearing seat 102 is installed on the rack 1, and the two ends of the second rotating shaft 301 are installed on the second bearing seat 102 through bearings, so that the second rotating shaft 301 is rotatably installed on the rack 1.

[0088] Preferably, the second bearing seat 102 is a Yiheda bearing seat with a model number of KP002-ASAHI.

[0089] According to the embodiments of the utility model, a linear bearing 304 is installed on the swing arm 302, a guide shaft 305 is installed on the linear bearing 304, the guide shaft 305 is connected with the scraper 303, and the scraper 303 faces the glue applying roller 202.

[0090] Preferably, the linear bearing 304 is a Yiheda linear bearing with a model number of J-LMF11-d12, and the guide shaft is a Yiheda guide shaft with a model number of SHX31-D12-L85-E2-B10-P8.

[0091] A five-star handle 306 is installed on the swing arm 302, and the five-star handle 306 has a screw rod. The screw rod of the five-star handle 306 is threadedly connected with the swing arm 302. The screw rod of the five-star handle 306 penetrates through the swing arm 302 and is connected with the scraper 303 through a first spring 307.

[0092] The swing arm 302 is provided with a pin hole 310, and the rack 1 is provided with a locking fixing member 311. The locking fixing member 311 and the pin hole 310 are locked by a knob plunger pin shaft 312.

[0093] Specifically, by manually rotating the swing arm 302 around the second rotation shaft 301, the swing arm 302 drives the scraper 303 to rotate to the working position (the scraper 303 faces the tangential direction of the rotation of the upper rubber roller 202). Figure 6 And Figure 7 Specifically, by manually rotating the swing arm 302 around the second rotation shaft 301, the swing arm 302 drives the scraper 303 to rotate to the working position (the scraper 303 faces the tangential direction of the rotation of the upper rubber roller 202).

[0094] When the swing arm 302 drives the scraper 303 to rotate to the working position (the scraper 303 faces the tangential direction of the rotation of the upper rubber roller 202), the scraper 303 is in contact with the upper rubber roller 202, and the first spring 307 is compressed, and the compression amount of the first spring 307 increases, and the scraper 303 moves away from the upper rubber roller 202.

[0095] When the swing arm 302 drives the scraper 303 to rotate to the working position (the scraper 303 faces the tangential direction of the rotation of the upper rubber roller 202), the compression amount of the first spring 307 decreases, and under the action of the elastic force of the first spring 307, the scraper 303 moves close to the upper rubber roller 202 and makes the scraper 303 contact with the upper rubber roller 202.

[0096] During the movement of the scraper 303 close to or away from the upper rubber roller 202, the guide shaft 305 slides along the linear bearing 304 to guide the movement of the scraper 303 close to or away from the upper rubber roller 202.

[0097] When the swing arm 302 drives the scraper 303 to rotate to the working position (the scraper 303 faces the tangential direction of the rotation of the upper rubber roller 202), the swing arm 302 is locked by inserting the knob plunger pin shaft 312 into the locking fixing member 311 and the pin hole 310.

[0098] Preferably, the knob plunger pin shaft 312 is a C-PXYKN12 type.

[0099] After the swing arm 302 and the scraper 303 rotate to the working position, the five-star handle 306 is rotated in both directions to drive the screw rod of the five-star handle 306 to rotate in both directions, thereby adjusting the compression amount of the first spring 307 and adjusting the pressure of the scraper 303 on the upper rubber roller 202.

[0100] Further, the glue scraping mechanism 3 further comprises a nut 313, which is in threaded connection with the screw rod of the five-star handle 306 to lock or loosen the five-star handle 306.

[0101] When the pressure of the doctor blade 303 pressing on the upper rubber roller 202 needs to be adjusted, the nut 313 is screwed to loosen the screw rod of the five-star handle 306, the five-star handle 306 is rotated forward and backward to drive the screw rod of the five-star handle 306 to rotate forward and backward, the compression amount of the first spring 307 is adjusted, and thus the pressure of the doctor blade 303 pressing on the upper rubber roller 202 is adjusted.

[0102] When the pressure of the doctor blade 303 pressing on the upper rubber roller 202 is adjusted, the nut 313 is screwed in the opposite direction to lock the screw rod of the five-star handle 306.

[0103] According to the embodiment of the utility model, the swing arm piece 302 is connected with a pressure sensor 308 through the second spring 309, the pressure sensor 308 contacts the doctor blade 303 and is used for measuring the pressure of the doctor blade 303 pressing on the upper rubber roller 202.

[0104] Preferably, the pressure sensor 308 adopts a Shanghai Tianmu pressure sensor with a model number of NS-WL5-50KG-24-I-0.

[0105] The five-star handle 306 is rotated forward and backward to drive the screw rod of the five-star handle 306 to rotate forward and backward, the compression amount of the first spring 307 is adjusted, and thus the pressure of the doctor blade 303 pressing on the upper rubber roller 202 is adjusted, the pressure sensor 308 measures the pressure of the doctor blade 303 pressing on the upper rubber roller 202, and thus the pressure of the doctor blade 303 pressing on the upper rubber roller 202 is accurately adjusted, the control precision of the pressure of the doctor blade 303 pressing on the upper rubber roller 202 is improved, and the problem of uneven coating of the adhesive tape is avoided.

[0106] Specifically, when the five-star handle 306 is rotated forward to drive the screw rod of the five-star handle 306 to rotate forward, the compression amount of the first spring 307 is increased, the pressure of the doctor blade 303 pressing on the upper rubber roller 202 is increased, the reaction force of the upper rubber roller 202 on the doctor blade 303 is increased, and the pressure of the doctor blade 303 measured by the pressure sensor 308 is increased (that is, the pressure of the doctor blade 303 pressing on the upper rubber roller 202 is increased), and thus the pressure of the doctor blade 303 pressing on the upper rubber roller 202 is measured.

[0107] When the five-star handle 306 is rotated in the opposite direction to drive the screw rod of the five-star handle 306 to rotate in the opposite direction, the compression amount of the first spring 307 is reduced, the pressure of the doctor blade 303 pressing on the upper rubber roller 202 is reduced, the reaction force of the upper rubber roller 202 on the doctor blade 303 is reduced, and the pressure of the doctor blade 303 measured by the pressure sensor 308 is reduced (that is, the pressure of the doctor blade 303 pressing on the upper rubber roller 202 is reduced), and thus the pressure of the doctor blade 303 pressing on the upper rubber roller 202 is measured.

[0108] The pressure sensor 308 is connected with the swing arm part 302 through the second spring 309, so that the pressure sensor 308 is flexibly connected with the swing arm part 302 through the second spring 309, and the pressure sensor 308 can cover a large pressure adjustment range of the scraper 302 and the rubber coating roller 202.

[0109] Back to Figure 3 And Figure 4 According to the embodiment of the utility model, the transmission mechanism 5 includes motor 504, chain 502, first sprocket 503 and second sprocket 504.

[0110] The first sprocket 503 is fixed with the output shaft of the motor 501, and the second sprocket 504 is fixed with the first rotating shaft 201. The chain 502 is arranged around the first sprocket 503 and the second sprocket 504, so that the motor 501 drives the first rotating shaft 201 to rotate, and drives the rubber coating roller 202 and the movable hoop 203 of the rubber coating mechanism 2 to rotate synchronously. The rubber coating roller assembly M1 of the rubber coating roller 202 coats the hook-and-loop tape with glue.
