DETAILED DESCRIPTION

[0039] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0040] Example: Figure 1 and Figure 4As shown, a glue coating machine that effectively reduces noise includes: a support base 1 is a glue coating machine body that effectively reduces noise. The support base 1 is the main part of the glue coating machine, which plays the role of carrying all components of the glue coating machine. It mainly provides support and fixation for other components so that the glue coating machine can work stably. At the same time, the support base 1 has rubber on the part that contacts the ground, which can alleviate the vibration and noise between the glue coating machine and the ground. The top of the support base 1 is respectively fixed with a bracket 2 and a connecting pipe 3. The bracket 2 provides additional support and fixation for other components of the glue coating machine. Through the bracket 2, the weight of other important components of the glue coating machine can be effectively shared, and it is helpful to balance and disperse the load of the glue coating machine, thereby increasing the stability and bearing capacity of the overall structure. The connecting pipe 3 connects the fluid inside the glue coating machine to other components, thereby realizing the transmission and flow of the working medium inside the glue coating machine, and ensuring the normal glue coating operation of the glue coating machine. Secondly, a sensor is arranged at the position near the connecting pipe 3 inside the support base 1. The function of the sensor is to detect whether the plate has been transported to the vicinity of the glue outlet hole 9.Once the plate reaches the position of the sensor, the sensor will send a signal to notify the controller 13 of the position information of the plate. Once the sensor detects that the plate has reached the target position, the controller can control other components according to the signal of the sensor to control the operation of the glue outlet hole 9, so that it starts to discharge glue. This ensures that the glue is released at the right time and position, thereby achieving precise coating of the plate. The bottom of the connecting tube 3 is connected to a scraper 8, and a glue outlet hole 9 is penetrated on one side of the scraper 8. When the glue coating machine is running, glue will flow out of the glue outlet hole 9. The scraper 8 is located on one side of the glue outlet hole. When the plate moves, the glue is evenly applied to the plate by the scraper. The internal rotation of the support seat 1 is provided with a rotating shaft 10, and the outer surface of the rotating shaft 10 is covered with a conveyor belt 11. The rotating shaft 10 is a key component of the rotation and transmits power through the connection. When the rotating shaft 10 is connected to the first motor 12 installed on one side of the outer surface of the support seat 1, it can drive the conveyor belt 11 to operate to realize the transmission of the plate. At the same time, the middle of the outer surface of the support seat 1 A controller 13 is installed and located on the right side of the first motor 12. The controller 13 is electrically connected to the first motor 12, the second motor 22, the delivery pump 20, the electric heating plate 15, the first sensor 16, the second sensor 17 and the inductor. The controller 13 may be used to control the operation of the first motor 12, the second motor 22, the delivery pump 20 and the electric heating plate 15. Through the electrical connection with the controller 13, these devices can receive control signals and perform corresponding operations. The first sensor 16, the second sensor 17 and the inductor can be used to monitor the working status of the equipment or other monitoring, and transmit the corresponding feedback signal to the controller 13. The controller 13 can perform real-time monitoring, adjustment and prompt according to the feedback signals of these sensors. A glue tank 14 is installed at the bottom of the support seat 1. The glue tank 14 can be used to store glue to ensure sufficient glue supply during operation. At the same time, the glue tank 14 is made of sound insulation material, so that the sound generated by the operation of the internal structure is blocked, thereby reducing the propagation of noise.

[0041] like Figure 2As shown, it includes: a hollow cylinder 4 is fixed at the bottom of the bracket 2, so that the structure associated with it can move in the hollow part thereof, a movable rod 5 is penetrated at the bottom of the hollow cylinder 4, a roller seat 7 is installed at the bottom of the movable rod 5, and the roller seat 7 can contact the surface of the plate, a spring 6 is fixed on the upper part of the inside of the hollow cylinder 4, and the bottom end of the spring 6 is fixedly connected to the top end of the movable rod 5, and the movable rod 5 can realize the function of moving up and down by passing through the hollow cylinder 4, and the existence of the spring can balance the pressure applied to the roller seat 7 during glue coating, so that the roller seat 7 can contact the surface of the plate and can automatically The main adjustment roller seat 7 and the mutual resistance force between the plate, thereby improving the stability of the movement of the plate during operation. At the same time, the roller surface in the roller seat 7 is wrapped with rubber. The rubber-wrapped roller can effectively protect the surface of the plate from being scratched or damaged. Since rubber has good elasticity and wear resistance, it can reduce friction and impact on the surface of the plate during contact, avoid scratches or other damage during the gluing process, and increase friction at the same time, which is beneficial to maintain stable contact between the roller seat 7 and the plate during the gluing process, thereby ensuring that the plate can be more stable during transportation.

[0042] like Figure 3As shown, it includes: an electric heating plate 15 is installed on the inner wall of the glue liquid box 14, and a second motor 22 is installed on one side of the glue liquid box 14, and the output end of the second motor 22 is connected to a rotating rod 18 rotatably arranged inside the glue liquid box 14, and the rotating rod 18 is driven to rotate by the second motor 22, and then the stirring rod 19 fixed on the outer surface of the rotating rod 18 is driven to rotate. Such a design can achieve mixing and stirring of the glue liquid, ensure that the various parts inside the glue liquid are evenly mixed, avoid problems such as local uneven concentration and uneven composition, and improve the quality and stability of the glue liquid. Through the rotation of the stirring rod 19, the heat provided by the electric heating plate 15 can be evenly transferred to the glue liquid, the uniformity of the glue liquid temperature can be improved, and the temperature consistency of the entire glue liquid system can be ensured, so that the glue liquid can avoid solidification. At the same time, heating the glue liquid can maintain the viscosity of the glue liquid. First sensors 16 are installed at the lower sides of the interior of the glue liquid box 14. When the amount of glue liquid is not consistent with the first sensor 16, its first sensor The device 16 sends a signal to the controller 13, and then the controller 13 issues a prompt, requiring personnel to add glue to the glue tank 14. Second sensors 17 are installed at the lower sides of the interior of the glue tank 14, and the rotating rod 18 is located between the two groups of sensors. When the added glue contacts the second sensor 17, the second sensor 17 sends a signal to the controller 13, and then the controller 13 issues a prompt, prompting the personnel that the amount of glue added is sufficient. A delivery pump 20 is installed at the lower part of the interior of the glue tank 14, and a delivery pipe 21 is connected to the delivery end of the delivery pump 20. One end of the delivery pipe 21 is connected to the connecting pipe 3, and then the delivery pump 20 is connected to the connecting pipe 3 through the delivery pipe 21. The delivery pump 20 extracts glue from the glue tank 14 and transmits it to the connecting pipe 3 through the delivery pipe 21 connected to its delivery end. The delivery pump 20 can provide sufficient pressure and flow so that the glue can be smoothly transported from the glue tank 14 to the required position.

[0043] Working principle: personnel start the first motor 12, the second motor 22, and the electric heating plate 15 through the controller 13. The electric heating plate 15 heats the glue liquid. At the same time, the second motor 22 drives the rotating rod 18 to drive the stirring rod 19 to stir the glue liquid to prevent the glue liquid from solidifying and maintain the viscosity of the glue liquid. The first motor 12 drives the rotating shaft 10 to rotate, and the rotating shaft 10 drives the conveyor belt 11 to move. Personnel place the plate on the conveyor belt 11. The surface of the plate contacts the roller of the roller seat 7. During the movement of the plate, the roller seat 7 is gradually lifted upward. The roller seat 7 drives the movable rod 5 to squeeze the spring 6 to contract. At the same time, the spring 6 also applies a reset force to the movable rod 5, which causes the roller seat 7 to touch the plate. When the sensor contacts the signal of the plate , its signal is transmitted to the controller 13, the controller 13 controls the delivery pump 20 to discharge the glue liquid to the plate through the delivery pipe 21, the connecting pipe 3 and the glue outlet. As the plate moves from left to right, the scraper 8 evenly spreads the glue liquid on the plate. After the sensor does not sense the plate, the controller turns off the delivery pump 20. During the use of the glue liquid, the amount of glue liquid gradually decreases until it is not in contact with the first sensor 16. The first sensor 16 sends information to the controller, which triggers an alarm. When glue liquid is added to the inside of the glue liquid box, when the glue liquid contacts the second sensor 17, the information is sent to the controller 13. The controller 13 issues a prompt to remind the personnel that the amount of glue liquid added is sufficient, which is convenient for the personnel to add glue liquid in time.
