Abstract
Description
Technical Field
[0001] This utility model relates to the field of paperboard production technology, and in particular to a paperboard bonding device. Background Technology
[0002] Cardboard bonding refers to the process of bonding multiple layers of cardboard together using adhesives.
[0003] The announcement number CN219191469U describes a cardboard bonding device for carton production, comprising a desktop, columns fixedly connected to the left and right sides of the desktop, a top plate fixedly connected between the two columns, a cylinder fixedly connected to the bottom of the top plate, a connecting block fixedly connected to the output end of the cylinder, connecting rods rotatably connected to both sides of the connecting block, two side plates fixedly connected to the top right of the desktop, three evenly distributed rotating shafts rotatably connected between the two side plates, and a dust-adhesive roller, a coating roller, and a uniform coating roller rotatably connected to the outer diameter of the three rotating shafts, respectively.
[0004] Based on the above technical features, the problem is that in the process of applying glue to the cardboard, the existing cardboard bonding device requires the cardboard to be upside down on the side plate. Then, the dust-adhesive roller, coating roller, and uniform coating roller sequentially clean the bottom of the cardboard, apply glue, and flatten it. As a result, after the cardboard is glued, the upside-down setting makes it easy for the glue to drip from the bottom of the cardboard, affecting the subsequent bonding operation. At the same time, when bonding the upper and lower cardboard, manual intervention is required to align the upper cardboard with the lower cardboard and then put the upper cardboard on the lower cardboard. The degree of automation is low and the production efficiency is not high.
[0005] Therefore, it is necessary to solve the above problems by means of a cardboard bonding device. Utility Model Content

The liquid pump's outlet is fixedly connected to a nozzle 20, which is vertically downward.
[0029] Two placement plates 10 are installed on the base plate 1.
[0030] One of the placement plates 10 is horizontally positioned and fixed to the base plate 1. The placement plate 10 is located directly below the two pressure rollers 18. A limiting groove is provided on the placement plate 10, and the lower cardboard 7 is placed in the limiting groove. The placement plate 10 is provided with a notch, which connects to the limiting groove and matches the lower cardboard 7, allowing the lower cardboard 7 to slide in.
[0031] A mounting base is fixedly installed between the two support plates 13, and a second motor 9 is fixedly installed on the mounting base. The output shaft of the second motor 9 is horizontally positioned and fixedly connected to another placement plate 10, which is located below the nozzle 20. A glue-applying groove is provided on this placement plate 10, and an upper cardboard 8 is placed in the glue-applying groove. A clamping component is installed on this placement plate 10, and the clamping component abuts and limits the upper cardboard 8 to clamp and fix the upper cardboard 8.
[0032] The clamping component includes two clamping blocks 12, which slide relative to each other and are slidably installed into the glue coating groove. The upper cardboard 8 is located between the two clamping blocks 12, and both clamping blocks 12 are in abutting and limiting engagement with the upper cardboard 8. Two cylinders 11 are fixedly installed on the placement plate 10 with the glue coating groove. The telescopic shafts of the two cylinders 11 are horizontally opposite each other, and both telescopic shafts of the two cylinders 11 pass into the glue coating groove and are fixedly connected to a clamping block 12.
[0033] Two parallel and symmetrically arranged vertical plates 2 are fixedly mounted on the base plate 1. Two support plates 13 and two placement plates 10 are located between the two vertical plates 2. A power mechanism is installed on each of the two vertical plates 2. The following description uses one of the power mechanisms as an example, and the other power mechanism is the same.
[0034] The power mechanism includes a first motor 3, a transmission belt 4, and two pulleys. The first motor 3 is bolted to a vertical plate 2, and a support shaft is fixed to the vertical plate 2. A pulley is fixedly mounted on the output shaft of the first motor 3, and another pulley is rotatably mounted on the support shaft. The two pulleys are connected within the transmission belt 4.
[0035] Two drive belts 4 are located between two vertical plates 2, and a horizontal cleaning plate 5 is fixedly installed on each of the two drive belts 4. The two cleaning plates 5 are horizontally opposite each other and correspond one-to-one with the two placement plates 10. The cleaning plate 5 corresponding to the placement plate 10 with the limiting groove slides in contact with the lower cardboard 7 in the limiting groove. The cleaning plate 5 corresponding to the placement plate 10 with the glue coating groove slides in contact with the upper cardboard 8 in the glue coating groove.
[0036] An applicator roller 6 is rotatably mounted on a transmission belt 4 containing a cleaning plate 5 that slides in contact with the upper cardboard 8. The applicator roller 6 is positioned horizontally and parallel to the cleaning plate 5. The belt lengths of the applicator roller 6 and the cleaning plate 5 along the conveying direction and the reverse conveying direction are the same, while the applicator roller 6 rolls and abuts against the upper cardboard 8.
[0037] Working principle: When it is necessary to bond the upper cardboard 8 and the lower cardboard 7, the lower cardboard 7 is placed in the limiting groove, and the upper cardboard 8 is placed in the glue application groove. Then, the two cylinders 11 are activated, and the telescopic shafts of the two cylinders 11 extend and move closer to each other. At this time, the telescopic shafts of the two cylinders 11 push the two clamping blocks 12 to clamp and fix the upper cardboard 8.
[0038] After the upper cardboard 8 is clamped and fixed, the two cylinders 11 are shut down and the two first motors 3 are started. At this time, the two first motors 3 drive the connected pulleys to rotate, and the two pulleys drive the cooperating transmission belts 4. The two transmission belts 4 drive the connected cleaning plates 5 to move. The cleaning plate 5 corresponding to the upper cardboard 8 cleans the glued surface of the upper cardboard 8, and the cleaning plate 5 corresponding to the lower cardboard 7 cleans the adhesive surface of the lower cardboard 7.
[0039] During this process, the cleaning plates 5 for cleaning the upper cardboard 8 and the lower cardboard 7 move from the front to the rear, and the coating roller 6 moves from the rear to the front. The placement plate 10 where the upper cardboard 8 is located is positioned between the cleaning plates 5 on the transmission belt 4 where the coating roller 6 and the paint roller 6 are located. At this time, the two first motors 3 are turned off and the liquid pump is started, which sprays the glue in the glue storage tank 19 onto the upper cardboard 8.
[0040] After spraying is complete, the liquid pump is turned off, and simultaneously, the two first motors 3 are activated. At this time, the output shafts of the two first motors 3 drive the connected pulleys to rotate, and the two pulleys drive the cooperating transmission belt 4. During this process, the two cleaning plates 5 move from the rear to the front, and the coating roller 6 moves from the front to the rear, spreading the glue evenly on the cardboard 8.
[0041] After the mixture is evenly spread, the two first motors 3 are turned off, and the second motor 9 is started simultaneously. The output shaft of the second motor 9 drives the connected placement plate 10 to rotate 180 degrees around the output shaft of the second motor 9, thereby securing the upper cardboard 8 onto the lower cardboard 7. Then, the two cylinders 11 are started again, and their telescopic shafts retract, releasing the two clamping blocks 12 from holding the upper cardboard 8. At the same time, the output shaft of the second motor 9 reverses and drives the connected placement plate 10 back to its original position, that is, rotates 180 degrees to a horizontal position. In this embodiment, the second motor 9 is equipped with a brake device.
[0042] Then, hydraulic cylinder 14 is activated, and its telescopic shaft extends downward, causing the fixed base 15 to move downward. At this time, the fixed base 15 causes the two pressure plates 16 to move downward, and the two pressure plates 16 cause the two pressure rollers 18 to move downward. When the two pressure rollers 18 contact the upper cardboard 8, they roll apart. Simultaneously, the two pressure rollers 18 cause the two pressure plates 16 to rotate and separate, stretching the spring 17 between the two pressure plates 16. This presses the upper cardboard 8 and the lower cardboard 7 together.
[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
