[0026] The embodiment of the present utility model provides a reciprocating glue - applying device. Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 , which mainly includes a bearing plate, a glue cylinder, a glue - applying claw, a driving assembly and a glue - applying block.

[0027] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5In the embodiment of the present application, the strip of box paper is transported to the carrier plate 1, a glue cylinder 2 is arranged below the carrier plate 1, a glue claw 3 is arranged on the straight line formed by the carrier plate 1 and the glue cylinder 2, and a driving component 4 is arranged on one side of the glue claw 3. The driving component 4 and the glue claw 3 are fixedly connected. The driving component 4 drives the glue claw 3 to reciprocate between the carrier plate 1 and the glue cylinder 2. When the glue claw 3 is in the glue cylinder 2, the glue claw 3 is stained with glue, and then the glue claw 3 moves to the position of the carrier plate 1 to glue the strip of box paper on the carrier plate 1. After the glue is applied, the glue claw 3 moves to the position of the glue cylinder 2 to replenish the glue. The glue claw 3 reciprocates between the carrier plate 1 and the glue cylinder 2, and the glue stuck to the glue claw 3 will only fall under the action of gravity, avoiding the splashing of glue and ensuring the cleanliness of the cigarette production environment.

[0028] As a preferred embodiment of the present invention, two glue cylinders 2 and two glue claws 3 are provided, and the two glue cylinders 2 are provided on both sides of the carrying plate 1, and the two glue cylinders 2 are provided directly below the carrying plate 1. It can be foreseen that when the glue claws 3 reciprocate, due to the effect of gravity, part of the glue on the glue claws 3 will fall from the glue claws 3. By providing the glue cylinder 2 directly below the carrying plate 1, the glue separated from the glue claws 3 will fall back into the glue cylinder 2, thereby avoiding the waste of glue.

[0029] In the embodiment of the present application, the driving assembly 4 includes a linear moving unit 41 and a driving unit 42. The two gluing claws 3 are fixed on the linear moving unit 41. The driving unit 42 drives the linear moving unit 41 to perform linear motion in the up and down directions between the carrier plate 1 and the glue cylinder 2. When the driving unit 42 drives the linear moving unit 41 to move upward, the linear moving unit 41 drives the gluing claw 3 to move upward to the position of the carrier plate 1 to glue the strip of box paper on the carrier plate 1; when the driving unit 42 drives the linear moving unit 41 to move downward, the linear moving unit 41 drives the gluing claw 3 to move downward into the glue cylinder 2 to replenish the glue on the gluing claw 3. The driving unit 42 drives the linear moving unit 41 and the gluing claw 3 to perform linear motion in the up and down directions between the carrier plate 1 and the glue cylinder 2, so that the sum of the paths for replenishing the glue and gluing is the shortest, which shortens the time interval between two gluings and improves the gluing efficiency of the strip of box paper.

[0030] For details, see Figure 2 In the embodiment of the present application, the driving unit 42 includes a driving shaft 421 and a connecting plate 422. The driving shaft 421 can rotate in two different directions. One end of the connecting plate 422 is integrally connected to the driving shaft 421. The other end of the connecting plate 422 and the linear moving unit 41 are both provided with connecting through holes. The other end of the connecting plate 422 and the linear moving unit 41 are connected to each other by a pin shaft and a connecting through hole to realize rotational connection. Figure 1From the perspective of [description], driving the rotating shaft 421 to rotate clockwise drives the connecting plate 422 to rotate clockwise, causing the connecting plate 422 to rise. This in turn drives the linear movement unit 41 and the glue - applying claw 3 to raise their heights. The glue - applying claw 3 moves to the position of the bearing plate 1 to apply glue to the strip carton paper on the bearing plate 1. Then, the driving shaft 421 rotates counterclockwise, driving the connecting plate 422 to rotate counterclockwise, causing the connecting plate 422 to lower. This drives the linear movement unit 41 and the glue - applying claw 3 to lower their heights, and the glue - applying claw 3 moves downward into the glue cylinder 2 to replenish the glue on the glue - applying claw 3. Then, the driving shaft 421 continues to rotate clockwise to achieve reciprocating glue application to the strip carton paper on the bearing plate 1.

[0031] Preferably, in order to expand the movement range of the glue - applying claw 3, the driving unit 42 further includes a connecting rod 423. The connecting rod 423 is arranged between the connecting plate 422 and the linear movement unit 41. Both ends of the connecting rod 423 are provided with connecting through - holes. One end of the connecting rod 423 and the other end of the connecting plate 422 are rotationally connected by inserting a pin shaft into the connecting through - hole. The other end of the connecting rod 423 and the linear movement unit 41 are rotationally connected by inserting a pin shaft into the connecting through - hole. During the up - and - down movement of the glue - applying claw 3, the connecting rod 423 adjusts the angles between the connecting rod 423 and the connecting plate 422 and between the connecting rod 423 and the linear movement unit 41 to improve the coherence of the up - and - down movement of the glue - applying claw 3.

[0032] In other embodiments of the present application, the driving unit 42 can be a guide - rod cylinder. The telescopic end of the guide - rod cylinder is fixedly connected to the cross - bar 4111 on the linear movement unit 41 in a screwed manner. When the guide - rod cylinder operates, it pushes the linear movement unit 41 to continuously move up and down for glue application to the strip carton paper and replenishing the glue on the glue - applying claw 3.

[0033] Specifically, referring to Figure 3 , in the embodiment of the present application, the linear movement unit 41 includes a sliding bracket 411 and a slide rail 412. The sliding bracket 411 is provided with a card slot, and the slide rail 412 is welded to the frame around the glue - applying device. The sliding bracket 411 is fitted with the slide rail 412. The sliding bracket 411 is provided with an installation threaded hole, and the glue - applying claw 3 is provided with an installation through - hole. After a screw passes through the installation through - hole, it is screwed into the installation threaded hole to connect the glue - applying claw 3 and the sliding bracket 411. And the sliding bracket 411 is provided with a protruding block integrally connected to the sliding bracket 411. The protruding block is provided with a connecting through - hole, and the protruding block and the connecting rod 423 are rotationally connected by the above - mentioned method of connecting with a pin shaft. Figure 1From the perspective of [description], the driving rotating shaft 421 rotates clockwise, driving the connecting plate 422 to rotate clockwise, and the connecting plate 422 rises, thereby driving the sliding bracket 411 and the glue - applying claw 3 to lift. The glue - applying claw 3 moves to the position of the bearing plate 1 to apply glue to the strip box paper on the bearing plate 1. Then, the driving rotating shaft 421 rotates counterclockwise, driving the connecting plate 422 to rotate counterclockwise, and the connecting plate 422 descends, thereby driving the sliding bracket 411 and the glue - applying claw 3 to lower. The glue - applying claw 3 moves downward into the glue cylinder 2 to replenish the glue liquid on the glue - applying claw 3. Then, the driving rotating shaft 421 continues to rotate clockwise to achieve reciprocating glue application to the strip box paper on the bearing plate 1.

[0034] Preferably, the sliding bracket 411 is composed of a cross - bar 4111 and vertical bars 4112 arranged on both sides of the cross - bar 4111. The two vertical bars 4112 and the cross - bar 4111 are integrally connected. The card slot and the protruding block are arranged on the cross - bar 4111, and the vertical bar 4112 is screwed to the glue - applying claw 3.

[0035] Refer to Figure 5 , in the embodiment of the present application, a plurality of glue - applying blocks 5 are arranged on the glue - applying claw 3. The plurality of glue - applying blocks 5 and the glue - applying claw 3 are integrally connected. The glue - applying blocks 5 adhere to the glue liquid in the glue cylinder 2, and then rise to the position of the bearing plate 1 under the action of the rotation of the driving rotating shaft 421, and abut against the surface of the strip box paper on the bearing plate 1 to apply glue to the strip box paper on the bearing plate 1.

[0036] Specifically, refer to Figure 4 , a plurality of symmetric glue - applying holes 11 are arranged at both ends of the bearing plate 1. The glue - applying holes 11 are located directly above the glue cylinder 2. When the glue - applying claw 3 rises to the position of the bearing plate 1 under the action of the rotation of the driving rotating shaft 421, the glue - applying blocks 5 are fitted with the glue - applying holes 11 to apply glue to the strip box paper on the bearing plate 1. By arranging the glue - applying holes 11 directly above the glue cylinder 2, if too much glue is applied to the strip box paper, the excess glue will fall from the glue - applying holes 11 and fall into the glue cylinder 2, avoiding waste of glue. And by arranging a plurality of glue - applying holes 11, the number of glue - applying points on the strip box paper increases, making the strip box paper stick better. By arranging the glue - applying holes 11 symmetrically, the glue - applying effect on the strip box paper is beautiful.

[0037] In order to avoid the upper surface of the glue - applying claw 3 and the lower surface of the bearing plate 1 coming into contact with each other multiple times during the glue - applying process, resulting in the accumulation of glue scale on the lower surface of the bearing plate 1, in the embodiment of the present application, the height of the glue - applying block 5 is greater than the depth of the glue - applying hole 11.
