[0021] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort should fall within the scope of protection of this utility model.

[0022] A roller glue machine for easy cleaning of adhesive residue includes two side frames 1. Two cooperating upper rollers 2 are rotatably mounted on the upper side between the two side frames 1. In this invention, when only the two upper rollers 2 are installed between the two side frames 1, without the two lower rollers 12 installed below the upper rollers 2, this invention can be used as a single-sided roller glue machine. In this case, a cleaning device for cleaning the adhesive residue between the two upper rollers 2 is only needed on the upper side between the two side frames 1. When, in addition to the two upper rollers 2, two lower rollers 12 are also installed below the upper rollers 2 between the two side frames 1, this invention can be used as a double-sided roller glue machine. In this case, in addition to the cleaning device for cleaning the adhesive residue between the two upper rollers 2, a cleaning device for cleaning the adhesive residue between the two lower rollers 12 is also needed on the upper side between the two lower rollers 12. Both the upper rollers 2 and the lower rollers 12 are driven to rotate by a motor.

[0023] Upper blocking plates 8 are respectively provided on both sides between the upper rollers 2 on both sides. Upper cylinders 9 are respectively fixedly installed on the upper side of the two machine frames 1. The piston rod of the upper cylinder 9 is fixedly connected to the upper blocking plate 8 on the corresponding side and drives the upper blocking plate 8 to move horizontally back and forth. The upper blocking plates 8 on both sides can be close to the end faces of the upper rollers 2 on both sides when the present invention is working, so as to prevent the glue between the upper rollers 2 on both sides from flowing out from both ends between the upper rollers 2 on both sides. The upper blocking plates 8 on both sides are driven to move horizontally by the upper cylinders 9 on both sides. The upper cylinders 9 on both sides are respectively fixedly installed on the two machine frames 1. The present invention can realize the automatic horizontal movement of the upper blocking plates 8 on both sides by setting the upper cylinders 9.

[0024] The left and right ends of the upper roller 2 are rotatably mounted on the two side frames 1 via upper rotating shafts 17. The front and rear sides of the upper blocking plate 8 are respectively provided with upper rotating shaft through holes 11 for the upper rotating shafts 17 on both sides of the upper roller 2 to pass through. The upper rotating shafts 17 on the left and right sides of the upper roller 2 pass through the upper rotating shaft through holes 11 on the corresponding side upper blocking plates 8. This invention, by having the upper blocking plates 8 respectively fitted onto the upper rotating shafts 17 on both sides of the upper roller 2, makes the upper blocking plates 8 more stable during horizontal movement, while the upper rotating shafts 17 on the upper roller 2 provide support for the upper blocking plates 8.

[0025] When the present invention is provided with two lower rollers 12, lower blocking plates 13 are respectively provided on both sides between the two lower rollers 12. Lower cylinders 14 are respectively fixedly installed on the lower side of the two machine frames 1. The piston rod of the lower cylinder 14 is fixedly connected to the lower blocking plate 13 on the corresponding side and drives the lower blocking plate 13 to move horizontally back and forth. The lower blocking plates 13 on both sides can be close to the end faces of the two lower rollers 12 when the present invention is working, so as to prevent the glue between the two lower rollers 12 from flowing out from both ends between the two lower rollers 12. The lower blocking plates 13 on both sides are driven to move horizontally by the lower cylinders 14 on both sides. The lower cylinders 14 on both sides are respectively fixedly installed on the two machine frames 1. By setting the lower cylinders 14, the present invention can realize the automatic horizontal movement of the lower blocking plates 13 on both sides.

[0026] The left and right ends of the lower roller 12 are rotatably mounted on the two side frames 1 via lower rotating shafts 15. The front and rear sides of the lower blocking plate 13 are respectively provided with lower rotating shaft through holes 18 for the lower rotating shafts 15 on the two side lower rollers 12 to pass through. The lower rotating shafts 15 on the left and right sides of the lower roller 12 respectively pass through the lower rotating shaft through holes 18 on the corresponding side lower blocking plates 13. This invention, by having the lower blocking plates 13 respectively fitted onto the lower rotating shafts 15 on the two side lower rollers 12, makes the lower blocking plates 13 more stable during horizontal movement, while the lower rotating shafts 15 on the lower rollers 12 provide support for the lower blocking plates 13.

[0027] The cleaning device includes a lead screw 3, a lead screw guide rod 4, a lead screw motor 5, and a scraper 6. The lead screw 3 is rotatably mounted between two side frames 1, and the two side frames 1 can respectively fix bearing seats for the lead screw 3. The motor is fixedly mounted on one side frame 1 and drives the lead screw 3. The motor can be driven by the lead screw 3 through a transmission structure such as a belt or gear. The bottom of the scraper 6 has two arc-shaped inner grooves 7 on both sides. The arc of the inner grooves 7 should be close to the outer diameter of the upper roller 2 or the lower roller 12. In this way, during the horizontal movement of the scraper 6, the inner grooves 7 on both sides can respectively come into close contact with the outer surface of the upper roller 2 or the lower roller 12, so that the scraper 6 can push the small amount of adhesive between the upper roller 2 or the lower roller 12 as far to the outside as possible. The bottom of the scraper 6 on the cleaning device between the upper roller 2 is inserted between the upper roller 6, and the bottom of the scraper 6 on the cleaning device between the lower roller 12 is inserted between the lower roller 12.

[0028] The upper side of the scraper 6 is provided with a threaded hole that mates with the lead screw 3 and a guide hole that mates with the lead screw guide rod 4. The lead screw 3 and the lead screw guide rod 4 pass through the threaded hole and the guide hole, respectively. When the lead screw 3 rotates, it drives the scraper 6 to move horizontally. The horizontal reciprocating movement of the scraper 6 can be realized by the forward and reverse rotation of the lead screw 3. By setting the lead screw guide rod 4 and making the lead screw guide rod 4 pass through the guide hole on the scraper 6, the scraper 6 can only move horizontally and cannot rotate during the horizontal movement.

[0029] A glue collection box 10 is installed on the lower side between the two sides of the frame 1. By installing the glue collection box 10, this utility model can be used to collect glue from between the upper rollers 2 on both sides or between the lower rollers 12 on both sides.

[0030] The scraper 6 has multiple drainage holes 16. By creating drainage holes 16 on the scraper 6, this invention can reduce the resistance of the scraper 6 when it moves to a certain extent. At the same time, the size of the drainage holes 16 should be smaller than the size of most of the rubber blocks.

[0031] The working process of this utility model:

[0032] In operation, when cleaning the adhesive between the two upper rollers 2 or the two lower rollers 12, the adhesive between these rollers is first partially consumed to avoid excessive waste. Then, when cleaning the adhesive between the two upper rollers 2, the upper cylinders 9 corresponding to the two upper blocking plates 8 are activated. The upper cylinders 9 drive the upper blocking plates 8 to move outwards. At this time, the adhesive between the two upper rollers 2 can flow out from both ends under the action of the scraper 6 and fall into the adhesive collection box 10. Similarly, when cleaning the adhesive between the two lower rollers 12, the lower cylinders 14 corresponding to the two lower blocking plates 13 are activated. The lower cylinders 14 drive the lower blocking plates 13 to move outwards. At this time, the adhesive between the two lower rollers 12 can flow out from both ends under the action of the scraper 6 and fall into the adhesive collection box 10. In box 10, because the viscosity of the adhesive is generally relatively high, it is difficult for the adhesive to flow out from both ends between the upper rollers 2 or the lower rollers 12 due to its own fluidity. Then, the lead screw motor 5 is turned on, which drives the lead screw 3 to rotate, thereby driving the scraper 6 to move horizontally. During the movement, the scraper 6 can push the adhesive between the two upper rollers 2 or the two lower rollers 12 to one side, so that the adhesive flows out from this side. When the scraper 6 moves close to the upper blocking plate 8 or the lower blocking plate 13 on one side, the lead screw motor 5 will drive the lead screw 3 to reverse. At this time, the lead screw 3 will drive the scraper 6 to move back. Through the reciprocating movement of the scraper 6, the scraper 6 can push most of the adhesive and almost all the adhesive blocks between the two upper rollers 2 or the two lower rollers 12 to the outside of the two upper rollers 2 or the two lower rollers 12. Finally, the flowing adhesive falls into the adhesive collection box 10.
