Description

Technical Field

[0001] The invention relates to the technical field of coating preheating, in particular to a VOC water-based UV plastic coating material preheating device. Background Art

[0002] VOC water-based UV plastic coating material is an environmentally friendly and efficient coating, widely used in various fields, mainly including emulsion, water dispersion type and water-soluble type. Water-based UV coating uses water to reduce the viscosity of the system, but UV curing is a fast process. If the water cannot be removed in time, it will have a negative impact on the performance of the coating, so preheating is required to remove the water.

[0003] In the prior art, there is a garden tree straightening device proposed in patent application number "CN202222018242.6". By setting a mixing and heating mechanism, when the serpentine stirring tube rotates clockwise and counterclockwise to stir the paint inside the inner shell, the tube wall and the paint exchange heat, so that the temperature of the paint rises after contacting the tube wall of the serpentine stirring tube.

[0031] The pretreatment mechanism includes four supporting plates 35 and four threaded rods 11. The four supporting plates 35 are fixedly connected to the outer wall. A transverse axis 7 is rotatably connected between the two supporting plates 35. The outer walls of the two supporting plates 35 are rotatably connected to the eccentric wheels 8 through the shaft. A mounting plate 6 is fixedly connected to the outer wall of the processing chamber 3 near one of the eccentric wheels 8. A motor 1 is installed on the outer wall of the mounting plate 6, and the output end of the motor 1 is connected to the eccentric wheel 8 through the shaft, and the eccentric wheel 8 is fixedly connected to the transverse axis 7 through the shaft.

[0033] When in use, the material to be preheated is poured into the processing bin 3, so that the material passes through the filtration of the filter plate 13 and falls into the preheating barrel 1 through the telescopic discharge pipe 16, so that the agglomerates contained in the material can be filtered on the upper surface of the filter plate 13. In this process, the motors installed on the two mounting plates 6 drive the eccentric wheels 8 to rotate at the same time. Under the action of the eccentric force of each eccentric wheel 8, the processing bin 3 can be driven to move back and forth up and down to generate a vibration force, so that the filtering effect of the material is better, wherein each telescopic support rod 17 is compressed and extended accordingly with the up and down movement of the processing bin 3, and each support spring is continuously compressed and stretched accordingly, which plays a supporting and limiting role for the processing bin 3. At the same time, the two eccentric wheels 8 During rotation, the horizontal axis 7 rotates along with it.

Through the above operation, the agglomerates in the material to be preheated can be pre-dispersed to avoid affecting the subsequent preheating effect.

[0034] After the material falls into the preheating barrel 1, the interior of the preheating barrel 1 is heated by the heating rod 2 34, and the water in the water storage tank 2 is heated by the heating rod 1 29 at the same time, and the heated water is passed into the heating pipe 19 through the telescopic connecting pipe 1 20 by the liquid pump 5 in cooperation with the outlet pipe 2 27 and the outlet pipe 1 25, so that the water flows in the heating pipe 19 and finally flows back to the water storage tank 2 through the telescopic connecting pipe 3 31, so that the warm water circulates in the heating pipe 19 to heat the material in the preheating barrel 1, and at the same time, the vertical shaft 24 is driven by the motor 2 to rotate forward and reverse continuously, thereby increasing the contact area with the material and making the heating effect on the material more uniform. After preheating, the switch valve is opened, and the material can be discharged through the discharge pipe for use.

[0035] One end of the liquid pump 5 is fixedly connected to a water outlet pipe 27, and the other end of the liquid pump 5 is fixedly connected to a water outlet pipe 1 25. The end of the water outlet pipe 27 away from the liquid pump 5 is fixedly connected to the water storage tank 2, and a three-way valve 28 is installed on the outer wall of the water outlet pipe 1 25. The outer wall of the water outlet pipe 1 25 is fixedly connected with a telescopic connecting pipe 26 and a telescopic connecting pipe 1 20. The end of the telescopic connecting pipe 1 20 away from the liquid pump 5 is fixedly connected to the heating pipe 19, and a telescopic connecting pipe 3 31 is fixedly connected to the outer wall of the water storage tank 2 near the bottom end, and the telescopic connecting pipe 3 31 is fixedly connected to the other end of the heating pipe 19 away from the water storage tank 2. Both the telescopic connecting pipe 1 20 and the telescopic connecting pipe 3 31 have telescopic properties. When the heating pipe 19 is continuously reversed, the rotation of the heating pipe 19 will not be hindered. In the initial state of the three-way valve 28, the telescopic connecting pipe 1 20 can be connected to the water outlet pipe 1 25.

[0036] An annular scraper 21 is movably installed at the top of the preheating barrel 1, and two reciprocating screws 22 are rotatably connected to the bottom of the preheating barrel 1, and the annular scraper 21 is sleeved on the outer position of the two reciprocating screws 22. An annular water storage bin 23 is fixedly connected to the bottom of the annular scraper 21, and the end of the telescopic connecting pipe 26 away from the liquid pump 5 is fixedly connected to the annular water storage bin 23. A plurality of nozzles 33 are fixedly connected to the outer side and the inner wall of the annular water storage bin 23.

The two Motor three is connected to two reciprocating screws 22 respectively, and two circular holes are penetrated on the upper end surface of the annular scraper 21, and threads matching the reciprocating screws 22 are opened on the inner wall of the circular holes. When the reciprocating screw 22 rotates, the annular scraper 21 can be driven to reciprocate up and down with the cooperation of the threads, and the outer wall of the annular scraper 21 is arranged close to the inner wall of the preheating barrel 1, so as to scrape the residual material adhering to the inner wall of the preheating barrel 1. When the heating tube 19 heats the material and causes the internal pressure of the preheating barrel 1 to be too high, the pressure inside the preheating barrel 1 can be relieved through the pressure relief valve 30.

[0037] Specifically, after the material is preheated and discharged, after all the water flows into the water storage tank 2, the three-way valve 28 is turned to connect the water outlet pipe 1 25 with the telescopic connecting pipe 2 26. At this time, the liquid pump 5 can pump the water in the water storage tank 2 into the annular water storage bin 23 through the telescopic connecting pipe 26, and spray it out from each nozzle 33. At the same time, the motor 3 is started to drive the two reciprocating screws 22 to rotate simultaneously, which can drive the annular scraper 21 to reciprocate up and down along the two reciprocating screws 22 to remove the material remaining on the inner wall of the preheating barrel 1. The material is scraped and the annular water storage bin 23 is driven to reciprocate up and down inside the preheating barrel 1 at the same time. The nozzles 33 located on the outer wall of the annular water storage bin 23 can fully flush the inner wall of the preheating barrel 1, and the nozzles 33 located on the inner wall of the annular water storage bin 23 can fully flush the heating pipe 19.
