It should be noted that, in the above operation, when the gummed paper start end E1 is stuck to the coiled material, before the following coiled material is rolled in, the first pressing sheet 31 and the second pressing sheet 41 release the pressing on the gummed paper start end E1, so that the gummed paper is smoothly stuck and moves along with the coiled material, when the gummed paper is completely wound (one or two windings can be preset), the gummed paper is pressed again by the first pressing sheet 31 and the second pressing sheet 41 before the gummed paper is cut off, and after the gummed paper is cut off, the pressed gummed paper becomes a new gummed paper start end E1 to wait for the next cycle operation, and more specific operation principle is referred to below.

Further, the blocking assembly 801 is provided with a second guiding roller set 8011, and the second guiding roller set 8011 is opposite to the guiding roller set 90. When the adhesive tape clamping assembly 802 and the blocking assembly 801 move relatively, so that the adhesive surface of the adhesive tape clamping assembly 802 clamping the adhesive tape start end E1 abuts against the blocking assembly 801, after the adhesive tape is attached to the web in this state, the adhesive tape is also unreeled so as to be rolled together with the web and attached to the web, in this process, the adhesive tape and the web are simultaneously guided by the second guide roller group 8011 abutting against the guide roller group 90, and the adhesive tape entering between the second guide roller group 8011 and the guide roller group 90 is pressed and firmly attached to the web.

Referring to fig. 3-6, the stopping assembly 801 and the adhesive tape clamping assembly 802 may be arranged above and below, fig. 3 shows that the roll 2 is transported in the direction S1 and is wound into the reel 123 to form a roll cake L, the roll 2 passes through the space between the adhesive tape clamping assembly 802 and the stopping assembly 801, during which the adhesive tape starting end E1 of the adhesive tape 1 stored in a roll is already clamped by the adhesive tape clamping assembly 802, the clamping principle or scheme is as described above, and will not be described again, wherein the adhesive tape starting end E1 faces upward, and when the adhesive tape clamping assembly 802 is used for the first time, the adhesive tape starting end E1 can be pulled away manually and pulled to clamp; as the roll 2 is unwound and the roll 123 is wound up, the radius of the formed roll cake L is larger and larger, that is, the roll 123 winds more and more roll cake L, and finally reaches the preset amount, and the radius of the roll cake L finally reaches R, referring to fig. 1 and 4, the gummed paper holding assembly 802 further includes a support rod 10 and a first roller 20; the supporting rod 10 supports the axis of the first roller 20, and after the coiled material 2 is coiled and reaches a preset radius R for coiling cakes, the outline of the coiled material is abutted against the first roller 20. As shown in fig. 4, the telescopic rod 813 of an air cylinder ascends along the direction of arrow H3 to lift the adhesive tape clamping assembly 802, the adhesive tape start end E1 on the adhesive tape clamping assembly 802 ascends (the principle that the adhesive tape start end E1 is clamped on the adhesive tape clamping assembly 802 is described above: the first pressing sheet 31 and the second pressing sheet 41 press the adhesive tape start end E1 on the guide roller set 90, and the adhering surface faces upward), since the adhesive tape clamping assembly 802 faces the blocking assembly 801, and the web 2 passes through the space between the adhesive tape clamping assembly 802 and the blocking assembly 801 along the direction S1, the adhesive tape clamping assembly 802 can bring the adhering surface of the adhesive tape start end E1 into contact with the web 2 between the adhesive tape clamping assembly 802 and the blocking assembly 801 to adhere to the back surface of the web 2 during the ascending, and as the adhesive tape clamping assembly 802 ascends, the adhesive tape clamping assembly 802 abuts against the blocking assembly 801, the pressure between the adhesive holding assembly 802 and the blocking assembly 801 can firmly stick the adhesive starting end E1 to the back of the roll 2, as shown in fig. 4, as the adhesive has been stuck on the roll 2, as long as the adhesive 1 is unreeled, the adhesive can be rolled into the roll L along with the roll 2, as shown in fig. 5, at this time, the first cutter 81 cuts the roll 2, as the first cutter 81 and the second cutter 70 are respectively arranged along the conveying direction of the roll 2, that is, the first cutter 81 is in front of the blocking assembly 801, the adhesive starting end E1 is stuck to the back of the roll 2 at the blocking assembly 801, and after the roll 2 is cut by the first cutter 81, the tail end E2 connected to the roll L is continuously rolled into the roll L and the adhesive 1 is continuously unreeled, rolled into the roll connected to the roll L and sticks the outermost roll L; referring to fig. 6, after the adhesive tape 1 is wound into the outermost layer of the roll cake L for a predetermined number of turns, the second cutter 70 cuts the adhesive tape, and the cut tail end E3 of the adhesive tape is pushed and guided by the first roller 20, at this time, the roll cake L continues to rotate (as shown by arrow N), so as to wind the tail end E3 of the adhesive tape into the roll cake L, and the first roller 20 can prevent the tail end E3 of the adhesive tape from randomly falling into wrinkles under the action of self weight or static electricity after the adhesive tape is cut.

In the above, when the roll cake L is rolled up, before the above-mentioned process of cutting off the adhesive tape by the second cutter 70 occurs, the first pressing sheet 31 and the second pressing sheet 41 press the adhesive tape 1 first, and when the second cutter 70 cuts off the adhesive tape, the pressed adhesive tape 1 becomes a new adhesive tape start end E1; thereafter, the telescopic ram 813 of the cylinder moves in the opposite direction of H3 to drive the adhesive tape clamping assembly 802 to descend, and the state shown in fig. 3 is restored, and a new adhesive tape start end E1 waits for the next cycle. The above work is circulated, so that the coiled material can be automatically coiled into a plurality of rolls of cakes, and the tail end of each roll of cake can be automatically fixed by sticking adhesive paper. The reel 123 may be replaced and the next cake may be wound, and the starting end of the web material 2 may be manually drawn to be pre-wound on the reel 123.

Further, the automatic adhesive tape following and pasting system further comprises: a third guide roller 60 and a fourth guide roller assembly 50; the fourth guide roller assembly 50 is positioned between the guide roller group 90 and the third guide roller 60, and the fourth guide roller assembly 50 can move in the direction perpendicular to the conveying direction of the adhesive paper 1; the fourth guide roller 50 comprises a roller 501 and a pallet 502, and a gap d is formed between the outer surface of the roller 501 and the pallet 502; the adhesive paper start end E1 of the adhesive paper 1 is guided by the third guide roller 60, passes through the entrance gap d, and is clamped by the adhesive paper clamping assembly 802.

Referring to fig. 1 to 3, the adhesive tape 1 is stored in a roll form, and when it is unreeled, the back surface (non-adhering surface) passes through the third guide roller 60 and presses the third guide roller 60 to pass through the gap d, and finally, the adhesive tape start end E1 is fixed by the adhesive tape clamping assembly 802 to be lifted up and against the blocking assembly 801 so as to stick the adhesive tape start end E1 to the roll material passing between the adhesive tape clamping assembly 802 and the blocking assembly 801, and during the process of unreeling the adhesive tape, i.e. the process of winding the adhesive tape into the roll material, the push rod 814 (which may be a pneumatic cylinder) can drive the fourth guide roller set 50 to move up and down along the directions of the arrows H1 and H2 so as to pull the adhesive tape 1 out of the roll form for sticking into and reeling in the roll cake L along with the roll material, since the rolled adhesive tape 1 (e.g. transparent adhesive tape) needs a certain force to drag when unreeling, the design of the fourth guide roller 50 can drag the adhesive tape 1, prevent the clamping effect from being affected by the excessive reaction force acting on the adhesive tape clamping assembly 802 in the roll adhesive tape.
