[0002] Polyurethane adhesives have excellent shear strength and impact resistance, and are suitable for various structural bonding fields. They have excellent flexibility and rubber properties, and can adapt to the bonding of substrates with different thermal expansion coefficients. Polyurethane adhesives form a soft-hard transition layer between substrates, which not only has strong bonding strength, but also has excellent buffering and shock absorption functions. They are often used in bonding stress-bearing structural parts, such as the bonding of structural parts of metal, plastic, glass, wood, etc.

[0003] The patent authorization publication number is CN219923467U, which discloses a glue coating machine, including a workbench and two groups of glue coating rollers. The two groups of glue coating rollers are arranged at intervals along the height direction of the workbench to coat the plates to be coated between the two groups of glue coating rollers. Although the above patent can control the remaining amount of adhesive on the plates to be coated by adjusting the distance between the movable roller and the fixed roller to improve the coating quality, after the coating is completed, if the glue coating machine is not cleaned in time, the adhesive will solidify on the glue coating roller group and affect the later use. When cleaning, the two groups of glue coating rollers need to be cleaned manually, which increases the difficulty of cleaning.

[0004] Therefore, a low-glue polyurethane adhesive coating machine with an automatic cleaning function is needed. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The support frame 2 is provided on the base plate 1 by welding, and the roller rubber shaft 3 is rotatably provided on the support frame 2. The driving motor 4 is provided on the top of the support frame 2 by bolt connection. The output shaft of the driving motor 4 is connected to the roller rubber shaft 3. The sliding block 5 is slidably provided on the support frame 2. A liquid storage tank 6 is placed on the base plate 1. The top of the liquid storage tank 6 is connected and communicated with a connecting pipe 7. A spraying roller 8 is provided on the sliding block 5. The end of the connecting pipe 7 is connected to the spraying roller 8. Two rotating shafts 11 are rotatably provided on the base plate 1. The rotating shaft 11 is provided with a rotating shaft 11 by welding. A movable frame 12 is provided with a cleaning roller 13 on the rotating frame 12, and the cleaning roller 13 can contact the roller rubber shaft 3. Two scrapers 9 are arranged on the front side of the sliding block 5 by welding. An adjusting rod 10 is rotatably arranged at the bottom of the support frame 2, and the adjustment is threadedly connected to the sliding block 5. The adjusting rod 10 is rotated to drive the sliding block 5 to move, thereby adjusting the distance between the spraying roller 8 and the roller rubber shaft 3, thereby adjusting the coating thickness. An observation window is embedded in the liquid storage tank 6, and the height of the polyurethane adhesive in the liquid storage tank 6 can be visually checked through the observation window. A pull plate 14 is arranged on the top of the rotating shaft 11 by welding. The pull plate 14 increases the fulcrum between the hand and the rotating shaft 11, thereby facilitating the rotation of the rotating shaft 11.

[0025] When the glue coating machine is needed, the panel is placed on the base plate 1, and the polyurethane adhesive in the liquid storage tank 6 is pumped into the connecting pipe 7 through an external water pump, and then sprayed on the roller glue shaft 3 through the spray roller 8, and the driving motor 4 is turned on. The output shaft of the driving motor 4 rotates to drive the roller glue shaft 3 to rotate, and then the polyurethane adhesive on the roller glue shaft 3 is applied to the panel, thereby achieving low glue application. When the glue coating machine is not needed, hold the pull plate 14 and rotate the rotating shaft 11, so that the rotating frame 12 drives the cleaning roller 13 to rotate inward, and then the cleaning roller 13 contacts with the roller glue shaft 3, and then the cleaning agent is sprayed on the roller glue shaft 3, and the roller glue shaft 3 rotates, so that the cleaning roller 13 comprehensively cleans the roller glue shaft 3, thereby achieving the purpose of automatic cleaning and avoiding the polyurethane adhesive solidifying on the roller glue shaft 3 and affecting the later use.

[0027] When polyurethane adhesive needs to be applied to the panel, the motor 19 is turned on, and the starting shaft of the motor 19 rotates to drive one of the transmission rollers 18 to rotate, and then the multiple transmission rollers 18 are driven to rotate through the synchronous wheel 20 and the synchronous belt 21, and then the panel is placed between the contact roller 16 and the transmission roller 18. The transmission roller 18 rotates to transport the panel from left to right, thereby replacing manual work to push the panel between the contact roller 16 and the transmission roller 18, thereby achieving the purpose of automatic loading and improving the coating efficiency.
