DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example 1

[0022] See also Figure 1 , is a schematic structural diagram of the anti-adhesive curling device for the easily adhesive soft adhesive strip provided by the present invention.

[0023] The anti-adhesive curling device for easy-to-adhesive soft adhesive strips comprises a frame 1, a cloth component 2, an adhesive component 3 and a detection component 4.

[0024] A cloth assembly 2 and a rubber assembly 3 are arranged side by side on the top of the frame 1. The cloth assembly 2 and the rubber assembly 3 have basically the same structure, and both include a main shaft, a driving mechanism, a roller and a partition. The cloth assembly 2 also includes cloth rolls with the same number as the rollers.

[0025] The main shaft is a pneumatic shaft, which is horizontally mounted on the top of the frame 1, and the end is connected to the driving mechanism on the side of the frame 1. Eleven partitions are arranged at equal intervals along the main shaft, forming ten compartments. A roller is respectively mounted in each compartment on the main shaft.

[0026] For ease of description, the cloth component 2 is recorded as including a cloth spindle 21, a cloth drive mechanism 22, a cloth roller 23, a cloth partition 24, and a cloth roll 25; the rubber component 3 includes a rubber spindle 31, a rubber drive mechanism 32, a rubber roller 33, a rubber partition 34, and a rubber roll 35.

[0027] Ten cloth rolls 25 are respectively wound on ten cloth rollers 23 , with their tail ends fixed on the cloth rollers 23 and their head ends pulled out and respectively fixed on the rubber rollers 33 .

[0028] In particular, the material distribution spindle 21 is a key-type air-expanding spindle, and the rubber material spindle 31 is a slat-type air-expanding spindle. The key-type air-expanding spindle can inflate any number of key strips, thereby pressing any number of material distribution rollers 23 tightly and rotating synchronously with the material distribution spindle 21; or deflate any number of key strips, thereby relaxing any number of material distribution rollers 23 and rotating freely.

[0029] The slat-type air-inflating shaft can only be inflated and deflated synchronously, so that all the rubber rollers 33 are pressed tightly and rotate synchronously with the rubber main shaft 31; or all the rubber rollers 33 are relaxed and rotate freely.

[0030] The detection assembly 4 includes a crossbeam and ten detection units 41 disposed thereon, which are respectively disposed near ten rubber rollers 33. The detection unit 41 is a diffuse reflection laser detection unit, which is targeted at black rubber and has a background suppression function, and is used to check the curling of the rubber.

[0031] See also Figure 2 , is a schematic diagram of the structure of the anti-adhesive curling method of the easy-to-adhesive soft adhesive strip provided by the present invention, wherein Figure 2 -a is the initial state of step 1, Figure 2 -b is the final state of step 1, Figure 2 -c is the initial state of step 2, Figure 2 -d is the final state of step 2.

[0032] Under the above structure, the working mode of the easy-to-bond soft rubber strip anti-sticking curling device, that is, the easy-to-bond soft rubber strip anti-sticking curling method includes: Step 1: Curl the tape.

[0033] The large piece of rubber is cut into ten rubber strips by a multi-knife cutting machine, and falls into ten compartments of the rubber spindle 31 respectively, and adheres to the pads on the surfaces of ten rubber rollers 33 respectively.

[0034] At this time, the rubber main shaft 31 is controlled to be inflated to fix all the rubber rollers 33 , and the rubber main shaft 31 is driven by the rubber driving mechanism 32 to drive all the rubber rollers 33 to rotate, and the rubber strips are rolled between the pads to form ten rubber rolls 35 .

[0035] On the other hand, the cloth main shaft 21 is controlled to be deflated and relaxed, and the cloth roller 23 rotates freely. As the rubber roller 33 rotates, the pad cloth is naturally pulled and the pad cloth is drawn out from the cloth roll 25 for use by the rubber roll. It should be ensured that there is still a surplus in the cloth roll 25 after the rubber roll 35 is rolled up to prevent the pad cloth from being damaged due to excessive pulling.

[0036] After all the rubber materials are rolled into the rubber material roll 35, as the rubber material main shaft 31 continues to rotate, the detection range of the detection unit 41 is no longer black rubber material, but padding cloth. At this time, it can be determined that all the rubber materials have been rolled up, and the control device stops running.

[0037] Step 2, use of rubber.

[0038] The rubber material main shaft 31 is controlled to deflate and relax, and the rubber material reel 33 rotates freely. The tail end of the rubber material in one of the rubber material reels 35 is manually pulled up and fed into the post-process.

[0039] On the other hand, the cloth roll 25 corresponding to the rubber roll 25 pulled up above in the cloth main shaft 21 is controlled to be inflated, a corresponding cloth roller 23 is fixed, and the cloth main shaft 21 is driven by the cloth driving mechanism 22 to drive the cloth roller 23 to rotate in the opposite direction, and the pad cloth is retracted into the pad cloth roll 25.

[0040] As the fixed cloth roller 23 rotates, the pad cloth is naturally pulled, and the pad cloth is drawn out from the pulled-up rubber roll 35 and retracted into the pad cloth roll 25 .

[0041] After the release of the glue in this glue roll 25 is completed, the glue tail end in the next glue roll 35 is manually pulled up and fed into the post-process.

[0042] At this time, the material spindle 21 is controlled to release a previously fixed material drum 23 to relax, and the next material drum 23 is controlled to be fixed, and the operation of releasing the rubber material and taking back the pad is repeated. By analogy, until all the rubber rolls 35 are released.

[0043] After all the rubber in any rubber roll 35 is released, as the rubber spindle 31 continues to rotate, the detection range of the detection unit 41 is no longer black rubber, but padding cloth, that is, it is determined that the rubber roll 35 is released, and the control device stops running, waiting for the next cycle to start. Example 2

[0044] The difference from the first embodiment is that the cloth main shaft 21 and the rubber main shaft 31 are both key-type air-inflating shafts.

[0045] Under the above structure, the working mode of the easy-to-bond soft rubber strip anti-sticking curling device, that is, the easy-to-bond soft rubber strip anti-sticking curling method includes: Step 1: Curl the tape.

[0046] The large piece of rubber is cut into ten rubber strips by a multi-knife cutting machine, and falls into ten compartments of the rubber spindle 31 respectively, and adheres to the pads on the surfaces of ten rubber rollers 33 respectively.

[0047] At this time, the rubber main shaft 31 is controlled to be inflated to fix all the rubber rollers 33 , and the rubber main shaft 31 is driven by the rubber driving mechanism 32 to drive all the rubber rollers 33 to rotate, and the rubber strips are rolled between the pads to form ten rubber rolls 35 .

[0048] On the other hand, the cloth main shaft 21 is controlled to inflate, all the cloth rollers 23 are fixed, and all the cloth rollers 23 are driven to rotate through the cloth driving mechanism 22, so that the padding in the cloth roll 25 is released to the rubber roller 33 for use by the rubber roll.

[0049] Avoid damaging the pad by pulling it.

[0050] After all the rubber materials are rolled into the rubber material roll 35, as the rubber material main shaft 31 continues to rotate, the detection range of the detection unit 41 is no longer black rubber material, but padding cloth. At this time, it can be determined that all the rubber materials have been rolled up, and the control device stops running.

[0051] Step 2, use of rubber.

[0052] The position of the first rubber drum 33 in the rubber main shaft 31 is controlled to be inflated, the rubber drum 33 is fixed, and the rubber main shaft 31 is driven by the rubber driving mechanism 32 to drive the rubber drum 33 to rotate in the opposite direction. The tail end of the rubber in the rubber roll 35 is manually pulled up and fed to the subsequent process.

[0053] On the other hand, the cloth main shaft 21 is controlled to inflate a cloth roll 25 corresponding to the above-mentioned pulled-up rubber roll 25, fix a corresponding cloth roller 23, and drive the cloth main shaft 21 through the cloth driving mechanism 22 to drive the cloth roller 23 to rotate and retract the padding cloth into the padding cloth roll 25.

[0054] Avoid damaging the pad by pulling it.

[0055] After the rubber in the rubber roll 25 is released, the position of the first rubber roller 33 in the rubber spindle 31 is controlled to be deflated and relaxed, thereby releasing the rubber roller 33 .

[0056] Then, the position of the second rubber roller 33 in the rubber main shaft 31 is inflated to fix the rubber roller 33, and the rubber main shaft 31 is driven by the rubber driving mechanism 32 to drive the rubber roller 33 to rotate in the opposite direction. The rubber tail end of the next rubber roll 35 is manually pulled up and fed to the subsequent process.

[0057] Similarly, the cloth main shaft 21 is controlled to release a previously fixed cloth roller 23 to relax, and the next cloth roller 23 is controlled to be fixed, and the operation of taking back the pad is repeated. And so on, until all the rubber rolls 35 are released.

[0058] After all the rubber in any rubber roll 35 is released, as the rubber spindle 31 continues to rotate, the detection range of the detection unit 41 is no longer black rubber, but padding cloth, that is, it is determined that the rubber roll 35 is released, and the control device stops running, waiting for the next cycle to start.

[0059] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention.
