[0002] UV conformal coating, also known as ultraviolet curable conformal coating, is a protective material widely used in the electronics industry and other fields. The production process of UV conformal coating requires the thorough mixing of various raw materials to ensure that the components of each raw material are mixed. Therefore, a special raw material pretreatment device is used.

[0003] After use, existing pretreatment devices for mixing raw materials may have a lot of raw materials adhering to their inner walls. In order to avoid these residual raw materials affecting the next production ratio, it is necessary to manually reach into the treatment device and clean its inner walls, which is quite inconvenient. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the prior art: after use, the inner wall of the existing pretreatment device for mixing raw materials may be covered with a lot of raw materials. In order to avoid the impact of these residual raw materials on the next production ratio, it is necessary to manually put your hand into the treatment device and clean its inner wall, which is inconvenient. Therefore, a pretreatment device for raw materials for UV conformal adhesive production that is easy to clean is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

U-shaped scrapers are fixedly fitted onto the stirring rods on the same side of the rotating rod. The surface of the scrapers slides in contact with the inner wall of the machine body. A rotating ring is rotatably and sealingly mounted at the opening of the collection trough. A rotating shaft is rotatably mounted inside the opening of the rotating ring. The bottom end of the rotating shaft is fixedly connected to the wall of the collection trough via a connecting component. A reciprocating screw is fixedly installed at the top of the rotating shaft.

A liquid outlet pipe is fixedly installed in the mounting port. A vertical rod is fixedly installed at the top of the liquid outlet pipe. A through groove communicating with the liquid outlet pipe is opened at the top of the vertical rod. The two piston rods are slidably and sealed into the two through grooves respectively. A liquid storage tank is fixedly installed on the upper surface of the machine body. The liquid storage tank is filled with cleaning agent.

A rotating rod 2 is vertically rotatably installed inside the machine body 1. The top end of the rotating rod 2 extends out of the machine body 1 and has a vertically formed collection trough 3. Multiple openings 4 are symmetrically formed on the surface of the rotating rod 2. Multiple hollow stirring rods 5 are fixedly installed on the surface of the rotating rod 2, with one end of each stirring rod 5 covering one of the openings 4. U-shaped scrapers 6 are fixedly fitted onto the stirring rods 5 on the same side of the rotating rod 2. The surface of the scrapers 6 slides in contact with the inner wall of the machine body 1. A rotating ring 7 is rotatably installed at the opening of the collection trough 3. A rotating shaft 8 is rotatably mounted inside the ring opening of the rotating ring 7. The bottom end of the rotating shaft 8 is fixedly connected to the wall of the collection tank 3 via a connecting component. The connecting component includes a fixing ring 17 fixedly sleeved on the bottom end of the rotating shaft 8 and two connecting rods symmetrically fixedly mounted on the outer ring wall of the fixing ring 17. One end of each connecting rod is fixedly connected to the wall of the collection tank 3. A reciprocating screw 9 is fixedly mounted on the top end of the rotating shaft 8. A sliding plate 10 is threaded onto the reciprocating screw 9. The sliding plate 10 is restricted from rotation by a limiting component, which includes two limiting rods 18 symmetrically and vertically fixedly mounted on the upper surface of the machine body 1. The sliding plate 10 is slidably sleeved on the... On the two limiting rods 18, piston rods 11 are symmetrically fixedly installed on the lower surface of the slide plate 10. The surface of the rotating ring 7 has symmetrically opened mounting ports, and a liquid outlet pipe 12 is fixedly installed inside each mounting port. A vertical rod 13 is fixedly installed at the top of the liquid outlet pipe 12, and a through groove communicating with the liquid outlet pipe 12 is opened at the top of the vertical rod 13. The two piston rods 11 are respectively slidably and sealed into the two through grooves. A liquid storage tank 14 is fixedly installed on the upper surface of the machine body 1, and the liquid storage tank 14 is filled with cleaning agent. An inlet pipe 15 communicating with the inside of the liquid storage tank 14 is fixedly installed on the surface of the vertical rod 13. The inlet pipe 15 and the outlet pipe 12... Each part is equipped with a first one-way valve. The first one-way valve in the inlet pipe 15 is directed from the liquid storage tank 14 to the through groove, and the first one-way valve in the outlet pipe 12 is directed from the through groove to the collection tank 3. The reciprocating screw 9 is controlled to rotate by a drive assembly, which includes a drive motor 16. A U-shaped plate is fixedly installed on the upper surface of the machine body 1. The drive motor 16 is fixedly installed on the upper surface of the U-shaped plate, and the output shaft of the drive motor 16 passes through the U-shaped plate and is fixedly connected to the reciprocating screw 9. A filter screen is provided at the opening of the stirring rod 5 away from the rotating rod 2 to prevent raw materials from entering the stirring rod 5.

[0022] Initially, there is no cleaning agent in the storage tank 14. At this time, the various raw materials to be mixed are put into the machine body 1, and then the drive motor 16 is started to rotate the rotating rod 2 and multiple stirring rods 5. During this process, the surfaces of the two scrapers 6 will slide and contact the inner wall of the machine body 1, thereby scraping off the raw materials adhering to the inner wall of the machine body 1, so that the raw materials can be fully mixed. During this process, the reciprocating screw 9 will also rotate, and the slide plate 10 threaded on the reciprocating screw 9 will move the two piston rods 11 vertically back and forth. When the piston rod 11 moves down, the volume in the channel will decrease and the pressure will increase. The gas in the channel will enter the collection tank 3 from the liquid outlet pipe 12, and then the end of the multiple stirring rods 5 away from the rotating rod 2 will be sprayed out and act on the raw materials, which can improve the dispersion of the raw materials. When the piston rod 11 moves up, the volume in the channel will increase and the pressure will decrease. The gas in the outside will enter the channel from the liquid inlet pipe 15.

[0023] After the raw materials are mixed, the mixed raw materials are taken out from the machine body 1. Then, the cleaning agent is put into the storage tank 14, and then the drive motor 16 is started. At this time, the two piston rods 11 will draw the cleaning agent in the storage tank 14 into the end of the stirring rod 5 away from the rotating rod 2 and spray it onto the inner wall of the machine body 1. This can effectively reduce the stickiness of the raw materials adhering to the inner wall of the machine body 1 and improve the cleaning effect on the inner wall of the machine body 1.

[0024] After cleaning is complete, drain the cleaning agent from the storage tank 14 and add the next batch of raw materials to be mixed into the machine body 1 for mixing.

[0025] An air inlet pipe 19 is fixedly installed on the surface of the vertical rod 13. A second one-way valve is provided inside the air inlet pipe 19. The conduction direction of the second one-way valve is from the outside to the through groove. Valve switches 20 are provided on the surfaces of the air inlet pipe 19 and the liquid inlet pipe 15. Multiple valve switches 20 are used to control the opening and closing of multiple liquid inlet pipes 15 and air inlet pipes 19 respectively.

[0026] The liquid inlet pipe 15 and the air inlet pipe 19 can be closed by valve switch 20. When it is necessary to stir and mix the raw materials, the liquid inlet pipe 15 can be closed and the air inlet pipe 19 can be opened. At this time, during the vertical reciprocating movement of the piston rod 11, only the external gas will be drawn from the air inlet pipe 19 into the collection tank 3 and sprayed out from the opening at the end of the stirring rod 5 away from the rotating rod 2. The cleaning agent in the storage tank 14 will not enter the through tank from the liquid inlet pipe 15. When it is necessary to clean the inner wall of the machine body 1, the air inlet pipe 19 can be closed and the liquid inlet pipe 15 can be opened. At this time, during the vertical reciprocating movement of the piston rod 11, the cleaning agent in the storage tank 14 will be drawn from the liquid inlet pipe 15 into the collection tank 3 and sprayed out from the opening at the end of the stirring rod 5 away from the rotating rod 2. There is no need to frequently perform the tedious steps of filling and discharging the cleaning agent.

[0027] In this invention, after the various raw materials are mixed evenly, the raw materials are taken out. At this time, the cleaning agent can be poured into the storage tank 14. Then, the drive assembly controls the rotating rod 2 to rotate the multiple stirring rods 5. During this process, the surfaces of the multiple scrapers 6 will slide into contact with the inner wall of the machine body 1, thereby scraping off the raw materials adhering to the inner wall of the machine body 1. At the same time, the cleaning agent will also be sprayed intermittently from the end of the multiple stirring rods 5 away from the rotating rod 2 and act on the inner wall of the machine body 1, which can effectively reduce the stickiness of the raw materials and improve the cleaning effect on the inner wall of the machine body 1.
