Description

Technical Field

[0001] The invention relates to the technical field of self-adhesive bag processing equipment, in particular to a film coating system for self-adhesive bags. Background Art

[0002] In the field of food and daily chemical products, packaging bags are an indispensable item. When producing self-adhesive bags, it is necessary to stick adhesive strips on the opening position of the self-adhesive bags, so that the opening position of the self-adhesive bags can be bonded by the adhesive strips to achieve the self-adhesive effect. At present, a laminating machine is used to bond the adhesive strips to the self-adhesive bags to complete the connection between the adhesive strips and the self-adhesive bags; the traditional laminating mechanism requires manual pulling out of one end of the rolled self-adhesive bag and connecting it to the conveying mechanism, and it is necessary to manually adhere one end of the adhesive sticker to the adhesive area of ​​the self-adhesive bag. The operation is relatively complicated and cumbersome, and when the adhesive sticker wound on the reel is almost used up, one end of the adhesive sticker is separated from the reel, so it is easy to cause the adhesive sticker to be offset or not firmly adhered when adhering to the self-adhesive bag. There is a lack of a self-adhesive bag laminating system that can automatically pull and convey the self-adhesive bag, and there is no need to manually adhere the self-adhesive bag to the adhesive sticker in the initial stage, and when the adhesive sticker is almost used up, the remaining adhesive sticker can also be relatively stable and straightly adhered to the adhesive area of ​​the self-adhesive bag.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] In the present invention, when one end of the self-adhesive bag is in a state of being clamped by the first clamping roller and the second clamping roller, with the rotation of the first conveying roller and the second conveying roller, the third gear is driven to rotate synchronously counterclockwise through the transmission of the second pulley and the second transmission belt, thereby driving the first toothed rod meshing with it to move in the direction of the film sticking assembly, thereby driving the end of the self-adhesive bag in a fixed state to pass directly under the film sticking assembly. After passing the film sticking assembly, the end of the first toothed rod and the end of the lower pressing block are forced to drive the first toothed rod to descend, and the second spring contracts, so that the first toothed rod is disengaged from the third gear. The gear of the second clamping roller is disengaged from the first clamping roller, so that the toothed end at the bottom of the first clamping roller is meshed with the eighth gear, thereby terminating the movement of the end of the self-adhesive bag for the purpose of laminating. At this time, the tenth gear at the end of the second clamping roller moves to the side end of the eleventh gear and the two are meshed. The eleventh gear is rotated by the fourth pulley and the fourth transmission belt, thereby driving the ninth gear and the tenth gear to rotate in opposite directions, thereby controlling the first clamping roller and the second clamping roller to automatically convey the self-adhesive bag located therebetween, so as to assist the laminating operation of the film sticking assembly, thereby achieving the effect of automatically traction and conveying the self-adhesive bag.

[0013] In the present invention, when the self-adhesive bag is coated and the first clamping roller and the second clamping roller need to be controlled to reset, the driving motor is controlled to rotate in the reverse direction, driving the fourth gear to rotate clockwise, thereby driving the fifth gear to mesh with the sixth gear, and then driving the sixth gear to rotate clockwise. Under the transmission of the third pulley and the third transmission belt, the eighth gear is driven to rotate counterclockwise, thereby driving the first toothed rod to slide in the opposite direction and disengage from the lower pressure block. At this time, the first toothed rod loses its resistance force and rises under the action of the second spring to mesh with the third gear again, and then drives the first toothed rod to slide in the direction away from the lower pressure block through the clockwise rotating third gear, thereby achieving the effect of driving the first clamping roller and the second clamping roller to reset to the initial position for the subsequent self-adhesive bag traction and conveying operation.

[0014] In the present invention, before laminating the self-adhesive bag, the first clamping roller is first lifted up, the first clamping roller rises on the inner side of the rotating part, and the first spring contracts, so that a certain space is left between the first clamping roller and the second clamping roller. Then, one end of the self-adhesive tape is passed through between the first clamping roller and the second clamping roller, and then the first clamping roller is released. The first spring opens and resets to drive the first clamping roller to descend, so that the first clamping roller and the second clamping roller clamp the end of the self-adhesive bag to facilitate subsequent traction and transportation work.

[0015] In the present invention, the adhesive tape is wound on the winding drum, one end of the adhesive tape passes through the limiting groove on the limiting cylinder and the other end droops naturally, and the adhesive tape is limited by the limiting clamping plate, so that the adhesive tape can always move along the limiting groove, thereby achieving the effect that the remaining adhesive tape can also be relatively stably and straightly adhered to the adhesive area of ​​the self-adhesive bag when the adhesive tape is almost used up; as the first clamping roller and the second clamping roller pull the end of the self-adhesive bag through the limiting cylinder, the movement of the sliding block drives the third toothed rod to move, thereby driving the twelve gears to rotate, and then driving the thirteenth gear to rotate and drive the second toothed rod to descend, until the limiting cylinder descends to the point where one end of the adhesive tape adheres to the adhesive area of ​​the self-adhesive bag, at which time the first clamping roller and the second clamping roller begin to rotate to convey the self-adhesive bag, thereby achieving the effect of automatically adhering the adhesive tape to the adhesive area of ​​the self-adhesive bag.
