Compared with the prior art, impurities, dust and other dirt in the air will not enter the glue, and glue can be automatically fed and discharged, saving time and enhancing work efficiency. However, during the coating process, the coating head is prone to glue overflow, which affects the coating effect and is prone to waste. Utility Model Content

[0005] The utility model aims to provide a coating head for an edge anti-overflow glue type micro-concave coating machine to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A coating head for an edge anti-overflow glue type micro-dimpled coating machine comprises a tank body; a controller is fixedly installed at one end of the tank body, a feed pipe is fixedly connected to the top of the tank body, a valve is fixedly installed at the bottom of the tank body, a coating head body is fixedly connected to the bottom of the valve, a pipeline is fixedly installed around the tank body at the bottom of the controller, a temperature control component is arranged on one side of the tank body, the temperature control component is used to adjust the temperature of water flowing into the pipeline, and an adjustment component is arranged inside the tank body, the adjustment component is used to control the flow rate of adhesive flowing into the coating head body.

[0008] By closing the valve, the adhesive can be intercepted inside the tank to avoid glue leakage. By opening the valve, the adhesive can flow out from the inside of the tank, so as to facilitate the subsequent coating work using the coating head body. By supplying water into the inside of the pipe, the temperature of the adhesive inside the tank can be adjusted. At the same time, by setting a temperature control component, the temperature of the water inside the pipe can be adjusted to ensure that the temperature of the adhesive remains stable. By setting an adjusting component, the flow rate of the adhesive flowing downward from the tank can be adjusted.

[0009] A further improvement of the technical solution of the utility model is that the temperature control component includes a box body, which is fixedly connected to one side of the tank body, and one end of the box body is fixedly connected to the end of the pipeline, a water inlet pipe is fixedly installed on one side of the box body, a first partition is fixedly installed inside the box body, one side of the first partition is slidably connected to a baffle one by a spring one, and the baffle one fits with the inner wall of the box body, a second partition is fixedly installed inside the box body on the other side of the first partition, a piston plate is slidably connected between the first partition and the second partition, an electric push rod is fixedly installed on the top of the box body, the electric push rod extends into the interior of the box body and is fixedly connected between the piston plate, a heating tube is fixedly installed inside the box body at the bottom of the piston plate, the interior of the box body is slidably connected to a baffle two by a spring two, and the baffle two fits with the other side of the second partition, and a temperature sensor is fixedly installed on the inner wall of the tank body.

[0010] The above technical solution is adopted. In this solution, the temperature of the adhesive inside the tank body can be detected by using a temperature sensor. When it is detected that the temperature of the adhesive rises to a certain standard, the piston plate can be driven to move upward by installing an electric push rod, and at the same time, the air between the first partition plate and the second partition plate forms a negative pressure, which can adsorb the baffle plate to the other side and separate it from the inner wall of the box body, so that cooling water can enter the interior of the box body through the water inlet pipe. When the water flows to the other side of the first partition plate, the piston plate can be driven to move downward by using the electric push rod, and at the same time, a thrust is formed, which can push the baffle plate to one side. And push baffle plate 2 to the other side to separate from the second partition, so that cooling water can flow to the other side through the second partition, and supply cooling water to the inside of the pipe, so as to cool the adhesive, avoid excessive fluidity caused by excessive temperature of the adhesive, and avoid overflow of the adhesive due to excessive fluidity. When the temperature sensor detects that the temperature of the adhesive has dropped to a certain standard, water is guided to the inside of the pipe through the box again, and the heating pipe is turned on at the same time. The water can be heated by the heating pipe, avoiding the adhesive from solidifying due to low temperature.

[0012] By adopting the above technical solution, in this solution, water can enter the interior of the box body by opening a through hole, thereby facilitating the supply of water into the interior of the pipeline.

[0014] The above technical solution is adopted. In this solution, the water inlet and the drain outlet are provided to facilitate the flow of water inside the box, and the one-way valve is provided to prevent the water from flowing back.

[0015] A further improvement of the technical solution of the utility model is that the adjusting component includes a guide plate, which is fixedly connected to the inside of the tank body, a rotating rod is rotatably installed on the top of the guide plate through a bearing, a rotating plate is fixedly connected to one side of the rotating rod, the rotating plate is fitted with the top of the guide plate, a motor is fixedly installed on the top of the tank body on one side of the feed pipe, and the output shaft at the bottom of the motor is fixedly connected to the end of the rotating rod.

[0016] The above technical solution is adopted. In this solution, when the motor drives its output shaft to rotate, it can drive the rotating rod to rotate and at the same time drive the rotating plate to rotate along the top of the guide plate.

[0017] A further improvement of the technical solution of the utility model is that a plurality of circular holes with different radii are provided on the surface of the guide plate.

[0018] The above-mentioned technical solution is adopted. In this solution, by opening a number of circular holes with different radii on the surface of the guide plate, the rotating plate can be used to block different positions on the top of the guide plate, thereby adjusting the flow rate of the adhesive passing through the guide plate, avoiding the situation where the adhesive flow rate is too fast and causes glue overflow from the coating head body.

[0019] A further improvement of the technical solution of the utility model is that a plurality of balls are rotatably mounted inside the rotating plate, and each ball is fitted with the top of the guide plate.

[0020] By adopting the above technical solution, a number of ball bearings are installed to reduce the contact area between the top of the guide plate and the rotating plate. During the rotation of the rotating plate, the ball bearings can be driven to roll along the top of the guide plate, thereby reducing the wear of the guide plate and protecting the guide plate and the rotating plate.
