[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0022] An automatic primer spraying device for a glue applicator, as Figure 1 shown, includes a bottom shell 1, support feet 2 are fixedly connected to the bottom end of the bottom shell 1, a top rod 3 is fixedly connected to the outer wall of the bottom shell 1, a support plate 4 is slidably connected to the outer wall of the top rod 3, and a glue applicator head 5 is fixedly connected to the bottom end of the support plate 4. A set of left and right symmetric fixing plates 6 are fixedly connected to the top end of the bottom shell 1, and an adjusting plate 7 is slidably connected to the top end of the fixing plate 6. A fixing mechanism 8 is fixedly connected to the top end of the adjusting plate 7. An installation groove 9 is formed on the opposite side of the bottom shell 1 away from the fixing plate 6, and a transmission mechanism 10 is movably connected to the inside of the installation groove 9. The top end of the transmission mechanism 10 is fixedly connected to an installation shell 11, and a spray head 12 is fixedly connected to the top end of the installation shell 11.

[0023] During use, first, after placing the workpiece between the clamping plates 804, the screw rod 802 can be rotated by turning the handle 14. When the screw rod 802 rotates, it will drive the U-shaped plates 803 to approach each other, thereby driving the clamping plates 804 to approach each other. At this time, the clamping plates 804 will clamp and fix the workpiece. At the same time, the rubber pads 805 can effectively prevent the workpiece from being damaged during the clamping process. Through the fixing mechanism 8, the workpiece can be more stable during glue coating and primer spraying, thereby preventing the workpiece from shaking during processing, resulting in unqualified processing efficiency of the workpiece. At the same time, the adjustment through the screw rod 802 can be adjusted according to the size of the workpiece, thereby improving the applicability of the equipment. After the workpiece is fixed, the motor 1001 can be controlled to rotate. When the motor 1001 rotates, it will drive the first gear 1002 to rotate. Then, the first gear 1002 will drive the two second gears 1003 on both sides to rotate. Then, the second gears 1003 will drive the transmission tooth plate 1004 to rotate. At the same time, when the transmission tooth plate 1004 rotates, it will drive the rack 1005 to move back and forth. At the same time, the orientations of the transmission tooth plates 1004 are the same, so the two transmission tooth plates 1004 on both sides will drive the rack 1005 to move reciprocally. Through the transmission mechanism 10, the nozzle 12 can be controlled to move back and forth, which can effectively improve the uniformity of paint spraying, thereby improving the practicability of the equipment. In addition, this equipment can make the operation of personnel more convenient and fast.

[0024] As Figure 3 shown, the transmission mechanism 10 includes a motor 1001, a first gear 1002, second gears 1003, a transmission tooth plate 1004, and a rack 1005. The output end of the motor 1001 is fixedly connected to the axis of the first gear 1002. There are two second gears 1003 that are symmetrically arranged left and right. The transmission tooth plate 1004 is drivingly connected to the second gear 1003 through a bearing. One side of the transmission tooth plate 1004 is movably connected to the outer wall of the rack 1005. The motor 1001 is fixedly connected to the inside of the bottom shell 1. The first gear 1002 and the second gears 1003 are rotatably connected to the inside of the installation groove 9. A positioning rod 13 is fixedly connected to the inside of the installation groove 9, and the rack 1005 is slidably connected to the outside of the positioning rod 13. The top end of the rack 1005 is fixedly connected to the bottom end of the installation shell 11. The first gear 1002 meshes with the second gears 1003, and the transmission tooth plate 1004 meshes with the rack 1005.

[0025] When the motor 1001 rotates, it drives the first gear 1002 to rotate. Then, the first gear 1002 drives the second gears 1003 on both sides to rotate. Next, the second gears 1003 drive the transmission tooth plate 1004 to rotate. At the same time, when the transmission tooth plate 1004 rotates, it drives the rack 1005 to move back and forth. Also, the orientations of the transmission tooth plates 1004 are the same. Thus, the transmission tooth plates 1004 on both sides drive the rack 1005 to perform reciprocating motion. By controlling the front and back movement of the nozzle 12 through the transmission mechanism 10, the uniformity of paint spraying can be effectively improved, thereby enhancing the practicality of the equipment. In addition, this equipment makes it more convenient and efficient for operators.

[0026] As Figures 2 - 4 shown, the fixing mechanism 8 includes a fixing tube 801, a screw 802, a U-shaped plate 803, a clamping plate 804, and a rubber pad 805. One end of the screw 802 extends to the outside of the fixing tube 801, and the screw 802 is rotatably connected to the inside of the fixing tube 801. The U-shaped plate 803 is threadedly connected to the outer wall of the screw 802. One side of the clamping plate 804 is fixedly connected to one side of the U-shaped plate 803. The rubber pad 805 is fixedly connected to the inner wall of the clamping plate 804. The bottom end of the fixing tube 801 is fixedly connected to the top end of the adjusting plate 7. One end of the screw 802 is fixedly connected to a handle 14.

[0027] After placing the workpiece between the clamping plates 804, the screw 802 can be rotated by the handle 14. When the screw 802 rotates, it drives the U-shaped plates 803 to move closer to each other, thereby driving the clamping plates 804 to move closer to each other. At this time, the clamping plates 804 clamp and fix the workpiece. Meanwhile, the rubber pad 805 can effectively prevent the workpiece from being damaged during the clamping process. Through the fixing mechanism 8, the workpiece can be more stable during glue application and primer spraying, thereby preventing the workpiece from shaking during processing, which may lead to substandard processing efficiency. Also, the adjustment by the screw 802 can be adjusted according to the size of the workpiece, thus improving the applicability of the equipment.

[0028] The working principle is as follows:

[0029] After placing the workpiece between the clamping plates 804, the screw rod 802 can be rotated by turning the handle 14. When the screw rod 802 rotates, it will drive the U-shaped plates 803 to approach each other, thereby driving the clamping plates 804 to approach each other. At this time, the clamping plates 804 will clamp and fix the workpiece. At the same time, the rubber pads 805 can effectively prevent the workpiece from being damaged during the clamping process. Through the fixing mechanism 8, the workpiece can be more stable during glue application and primer spraying. After the workpiece is fixed, when the motor 1001 rotates, it will drive the first gear 1002 to rotate. Then, the first gear 1002 drives the second gears 1003 on both sides to rotate. Then, the second gears 1003 drive the transmission tooth plate 1004 to rotate. At the same time, when the transmission tooth plate 1004 rotates, it will drive the rack 1005 to move back and forth. At the same time, the orientations of the transmission tooth plates 1004 are the same, so the transmission tooth plates 1004 on both sides will drive the rack 1005 to perform reciprocating motion.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention.
