[0027] 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 of the embodiments.

[0029] In a specific embodiment of the utility model, the storage rack is used to hold paper pieces, and the mobile module can absorb the paper pieces in the storage rack, and then drive the paper pieces to pass through the glue roller 2, and the glue on the ring surface of the upper glue roller 2 will stick to the paper pieces, so as to achieve the effect of gluing the paper pieces, and then the mobile module drives the glued paper pieces to be sent to the paper barrel, sticks the paper pieces to the bottom of the paper barrel, and then releases the adsorption; the glue disc 15 is used to hold glue, and when the lower glue roller 3 rotates, the glue in the glue disc 15 will stick to the ring surface of the lower glue roller 3. Since the upper glue roller 2 is in contact with the lower glue roller 3, the ring surface of the upper glue roller 2 will always be covered with glue, so that the paper pieces can be continuously glued; by setting a heating mechanism, the glue disc 15 can be heated to reduce the solidification time of the glue;

[0030] This gluing method can fully coat the surface of the paper with glue, and will not cause the problem of glue waste due to the glue coating area being larger than the paper, or the glue coating area being smaller, resulting in the paper being loose. At the same time, the method of direct gluing with a rubber roller can also facilitate subsequent cleaning. That is, if glue is solidified on the rubber roller, it can also be melted by heating for cleaning.

[0031] The heating mechanism is a heating plate 21 , which is fixedly disposed on the bottom surface of the adhesive disc 15 , and the adhesive disc 15 is heated by the heat generated by the heating plate 21 .

[0032] The mobile module includes a vertical moving mechanism and a horizontal moving mechanism for driving the vertical moving mechanism to move horizontally. The vertical moving mechanism is provided with an adsorption mechanism. The adsorption mechanism is used to adsorb paper sheets. The height of the paper sheets can be adjusted by the vertical moving mechanism, and the horizontal position of the paper sheets can be adjusted by the horizontal moving mechanism. That is, in actual application, after the adsorption mechanism adsorbs the paper sheets, the height of the paper sheets is adjusted by the vertical moving mechanism to bring them out of the storage rack. Then, the horizontal moving mechanism is used to drive the paper sheets to pass through the gluing roller 2 and be coated with glue. After coating with glue, the paper sheets are brought to the paper barrel station, and the vertical moving mechanism is used to stick the paper sheets to the bottom of the paper barrel.

[0033] The horizontal movement mechanism includes a guide rail 13, a lead screw is rotatably arranged in the guide rail 13, a mounting plate 12 is slidably arranged in the guide rail 13, the lead screw and the mounting plate 12 are threadedly connected, and the lead screw is driven to rotate by a second motor 11;

[0034] The guide rail 13 is fixedly arranged on the bracket 14, and the second motor 11 is fixedly arranged at the end of the guide rail 13. The output end of the second motor 11 is fixedly connected to the end of the lead screw, so that the second motor 11 can drive the lead screw to rotate, and then achieve the effect of the lead screw driving the mounting plate 12 to move horizontally. The second motor 11 can use a servo motor as a driving force to achieve an effect of easier position control;

[0035] In some other embodiments, the horizontal movement mechanism may also use a telescopic cylinder to drive the mounting plate 12 to move horizontally, or may use a gear rack to drive the mounting plate 12 to move horizontally.

[0036] The vertical moving mechanism includes a double-axis cylinder 10, which is fixedly arranged on a mounting plate 12. The adsorption mechanism is fixedly connected to the telescopic end of the double-axis cylinder 10, and the telescopic function of the telescopic rod of the double-axis cylinder 10 is used to drive the adsorption mechanism to move up and down.

[0037] In some other embodiments, the vertical moving mechanism may also use a lead screw to achieve the effect of up and down movement, or may use a gear rack structure to achieve the effect of up and down movement.

[0038] The adsorption mechanism includes a vacuum suction cup 9, which is fixedly arranged at the telescopic end of the double-axis cylinder 10. The vacuum suction cup 9 is located directly above the storage rack. The vacuum suction cup 9 can use a vacuum generator as a power source to adsorb paper sheets.

[0039] Two supports 4 are fixedly arranged on the first frame 1, two ends of the upper rubber roller 2 are rotatably connected to the upper parts of the two supports 4 respectively, and two ends of the lower rubber roller 3 are rotatably connected to the lower parts of the two supports 4 respectively. The upper rubber roller 2 and the lower rubber roller 3 are driven to rotate by a driving device, and the rubber disc 15 is located between the two supports 4; that is, each support 4 is provided with upper and lower bearings, the two ends of the upper rubber roller 2 are respectively installed in the bearings above the two supports 4, and the two ends of the lower rubber roller 3 are respectively installed in the bearings below the two supports 4; the upper rubber roller 2 and the lower rubber roller 3 are arranged in parallel, that is, the axes of the two are parallel and on the same vertical plane; the annular surface of the upper rubber roller 2 is in contact with the annular surface of the lower rubber roller 3, so that the lower rubber roller 3 can take out the glue from the rubber disc 15, and then the upper rubber roller 2 can stick the glue from the lower rubber roller 3.

[0040] The driving device includes a first motor 5, the output end of the first motor 5 is fixedly connected to the end of the lower rubber roller 3, and power is transmitted between the upper rubber roller 2 and the lower rubber roller 3 through a gear set; two gear sets are provided, which are respectively installed on the upper rubber roller 2 and the lower rubber roller 3, and the two gears are meshed. When rotating, the linear speeds of the upper rubber roller 2 and the lower rubber roller 3 are the same; the first motor 5 is fixedly set on one of the supports 4.

[0041] The storage rack includes a paper storage rack 8, which is fixedly arranged on the second frame 6. Four limiting rods 19 are arranged on the paper storage rack 8, and both ends of the limiting rods 19 are detachably connected to the paper storage rack 8 through adjustment blocks 20;

[0042] In this embodiment, the paper storage rack 8 is composed of a fixing ring and a column. The fixing ring is provided with two upper and lower ones, and the columns are provided with four ones. The upper and lower ends of the columns are respectively fixedly connected to the upper and lower fixing rings, and the four columns are evenly distributed around the circumference.

[0043] The limiting rod 19 is fixedly connected to the adjusting block 20. The adjusting block 20 is provided with a plurality of through holes. Bolts are passed through the through holes and screwed into the fixing rings to realize the detachable connection between the adjusting block 20 and the paper storage rack 8. The position of the limiting rod 19 can be adjusted by passing the bolts through the through holes at different positions.

[0044] The four limiting rods 19 together limit the paper in the horizontal direction, that is, the paper is placed between the four limiting rods 19. According to the different diameters of the paper, the positions of the limiting rods 19 can be adjusted to limit the paper of different sizes.

[0045] The storage rack also includes a support plate 7, which is arranged in the paper storage rack 8. Four straight grooves matching the limit rods 19 are opened on the support plate 7, and the support plate 7 moves up and down through a lifting mechanism; the support plate 7 is used to carry paper sheets, and the straight grooves opened do not hinder the adjustment of the position of the limit rods 19; the lifting mechanism can drive the support plate 7 to move up and down. When in use, as the paper sheets are consumed one by one, the adsorption mechanism may not be able to contact the paper sheets below, so the lifting mechanism is used to drive the support plate 7 to move up, so that the adsorption mechanism can adsorb the paper sheets.

[0046] The lifting mechanism is a screw lift 16, which is arranged at the lower part of the second frame 6. The screw 18 of the screw lift 16 is rotatably connected to the bottom surface of the support plate 7. The screw lift 16 is driven by a third motor 17. When the screw 18 of the screw lift 16 is extended or retracted, the support plate 7 can be driven to move up and down. During this process, the straight groove on the support plate 7 can also prevent the support plate 7 from rotating with the screw 18 under the action of the limit rod 19.

[0047] Workflow: First, the preparation work before starting the machine. Adjust the position of the limit rod 19 according to the size of the paper to be processed so that the paper will not move horizontally after being put in. After the adjustment is completed, put the paper to be coated with glue into the storage rack, that is, put it between the four limit rods 19, and use the support plate 7 to carry it. After the paper is put in, the top layer of paper must not exceed the height of the limit rod 19 (to avoid the paper moving). Put glue in the glue disc 15, and start the heating plate 21 for heating to prevent the glue from solidifying. At the same time, start the first motor 5 to drive the lower glue roller 3 and the upper glue roller 2 to rotate. The lower glue roller 3 sticks glue from the glue disc 15, and the upper glue roller 2 sticks glue from the lower glue roller 3. After the preparation work is completed, start the second motor 11 to drive The lead screw rotates, which in turn moves the mounting plate 12, and moves the mounting plate 12 to above the paper storage rack 8, that is, moves the vacuum suction cup 9 to above the paper storage rack 8, and then uses the double-axis cylinder 10 to drive the vacuum suction cup 9 to move downward to absorb the top layer of paper, and then the double-axis cylinder 10 drives the vacuum suction cup 9 to move upward, and then the horizontal moving mechanism drives the mounting plate 12, that is, drives the vacuum suction cup 9 to move horizontally, so that it moves to the glue roller 2, and makes the paper pass along the top of the glue roller 2, so that the glue on the glue roller 2 is coated on the paper, and then the paper continues to move to the paper barrel station, and then the paper moves downward driven by the vertical moving mechanism and sticks to the bottom of the paper barrel, and then the vacuum suction cup 9 releases the adsorption, completing the paper sticking to the paper barrel.
