The structural and operational principles of the present utility model are described in detail below with reference to the accompanying drawings:
firstly, please see fig. 1 to fig. 5, a roller gluing system with forward and reverse gluing functions, comprising: the first roller 11 and the second roller 12 are in contact with each other to form a gluing gap 13, a glue groove 14 is formed above the gluing gap 13, the glue roller 20 can control positive direction rotation, horizontal displacement and vertical displacement, the glue roller 20 drives a release paper A to continuously feed in a belt shape, the rotation direction of the glue roller 20 is the same as the running direction of the release paper A, the glue roller 20 is selectively contacted under the first roller 11 to form a reverse gluing process, the reverse gluing process is defined as that the glue roller 20 is the same as the rotation direction of the first roller 11, the first roller 11 is adhered with glue downwards from the gluing gap 13 to form a forward gluing process, or the glue roller 20 is selectively contacted under the second roller 12 to form a forward gluing process, the forward gluing process is defined as that the glue roller 20 is contacted with the second roller 12 to form a reverse gluing process, and the glue is adhered with glue downwards from the gluing gap 13 to form a reverse gluing process. Wherein, a first scraper 111 is disposed above the first roller 11, a second scraper 121 is disposed above the second roller 12, when the first roller 11 rotates in the opposite direction, the first scraper 111 abuts against the first roller 11, and when the second roller 12 rotates in the forward direction, the second scraper 121 abuts against the second roller 12, and when the first roller 11 rotates in the forward direction or the second roller 12 rotates in the opposite direction, the first scraper 111 and the second scraper 121 are both in a non-contact state.
As shown in fig. 1 and 2, when the glue roller 20 performs a reverse gluing process, the first roller 11 and the second roller 12 are horizontally displaced and contact with each other, thereby sandwiching the glue groove 14 and the glue gap 13, and glue is disposed in the glue groove 14, the glue roller 20 rotates in a forward direction to drive the release paper a to form a continuous conveyance in the same direction, the glue roller 20 is parallel to the lower portion of the first roller 11, and sandwiches the release paper a between the first roller 11 and the glue roller 20, at the moment, the rotation direction of the first roller 11 is the same as the rotation direction of the glue roller 20, and the second roller 12 is opposite to the rotation direction of the glue roller 20, thereby controlling the flow of the glue flowing through the gap formed by the first roller 11 and the second roller 12, the second roller 12 rotates in the opposite direction to push the adhesive in the adhesive groove 14 toward the adhesive gap 13, so that the adhesive coating amount in the reverse adhesive coating process is increased, and the second scraper 121 does not contact the second roller 12, and further, the adhesive coating amount on the release paper a is effectively increased by coating the adhesive on the release paper a at the discharge end of the release paper a relative to the adhesive roller 20, so as to achieve the effect of coating in the opposite high gram weight, and when the adhesive coating amount needs to be reduced slightly, as shown in fig. 2, the second roller 12 is controlled to change to be the same as the rotating direction (i.e. the positive direction) of the adhesive roller 20, the adhesive is pushed away from the adhesive groove 14 by the rotating direction of the second roller 12, so that the adhesive flowing through the adhesive gap 13 can be reduced slightly, i.e. the adhesive supply amount is reduced in a fixed amount under the condition of not changing the rotating speed and the adhesive coating gap 13, therefore, the glue supply amount can be easily controlled and quickly adjusted, so that a glue reducing mode of a reverse high-gram-weight coating process is formed, in summary, the second scraper 121 is arranged above the second roller 12, when the glue roller 20 performs the reverse glue coating process, the second roller 12 rotates in the forward direction to push the glue in the glue groove 14 away from the glue coating gap 13, the glue coating amount of the reverse glue coating process is reduced, and the second scraper 121 props against the second roller 12, so that the glue is prevented from being carried away from the glue groove 14 by the second roller 12, and the glue reducing mode of reverse glue coating is effectively achieved.

Accordingly, the glue roller 20 is selectively moved to contact the first roller 11 or the second roller 12, and the forward and reverse rotation of the first roller 11 or the second roller 12 is switched, so that the following four glue coating amounts can be rapidly and stably adjusted, and the glue coating amounts are sequentially from large to small in the reverse glue coating process, the glue reducing mode of the reverse glue coating process, the forward glue coating process and the glue reducing mode of the forward glue coating process, so that the glue coating machine has the dual functions of forward glue coating and reverse glue coating, and can provide multiple different gram weight glue coating effects under the conditions of constant rotation speed and gap size, thereby effectively improving the practicability of the glue coating machine.

4. The roller coating system with forward and backward coating functions according to claim 1, wherein a first scraper is disposed above the first roller, and when the glue roller performs forward coating, the first roller rotates in the opposite direction to push the glue in the glue groove away from the coating gap, so that the coating amount of the forward coating process is reduced, and the first scraper abuts against the first roller to prevent the glue from being carried away from the glue groove by the first roller.
5. The roller coating system with forward and reverse coating functions of claim 4, wherein the first roller rotates in the forward direction to push the adhesive in the adhesive slot toward the adhesive gap, so that the adhesive coating amount of the reverse coating process is increased, and the first scraper does not contact the first roller.
6. The roller coating system with forward and backward coating functions according to claim 1, wherein the rubber roller is disposed on a horizontal displacement mechanism, the horizontal displacement mechanism comprises two connecting pieces, two horizontal sliding rails, at least one horizontal screw rod and at least one displacement motor, the two connecting pieces are pivoted at two ends of the rubber roller, the connecting pieces are slidably disposed on the horizontal sliding rails, one end of the horizontal screw rod is connected with the displacement motor, and the other end of the horizontal screw rod is connected with the connecting pieces.
7. The roller coating system with forward and backward coating functions according to claim 6, wherein the horizontal displacement mechanism is disposed on a vertical lifting mechanism, the vertical lifting mechanism comprises two bearing seats, a plurality of vertical screws, a plurality of vertical sliding rails and a plurality of lifting motors, the horizontal displacement mechanism is fixed on the bearing seats by the horizontal sliding rails and the displacement motors, the bearing seats are slidingly disposed on the vertical sliding rails, one end of the vertical screws is connected with the bearing seats, and the other end of the vertical screws is connected with the lifting motors.
8. The roller coating system with forward and reverse coating functions of claim 7, wherein the vertical lifting mechanism is disposed on a first frame, the first frame comprises at least four columns, and the vertical lifting mechanism is fixed to the columns by the vertical sliding rail and the lifting motor.
9. The roller coating system with forward and backward coating functions according to claim 8, wherein the first roller and the second roller are disposed on a second frame at the same horizontal plane, a receiving space is formed at the bottom of the second frame, the first frame is placed in the receiving space of the second frame, and the mounting position of the glue roller is corrected by the relative positions of the first frame and the second frame.
