[0030] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0031] Example 1

[0032] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0033] like Figures 1 to 8 As shown, a plastic shell surface brightening treatment device includes a frame 1, a closable sealed space 2 on the frame 1, a temperature control component inside the sealed space 2, and a spray component 4 inside the sealed space 2. The temperature control component is used to vaporize the solvent when the spray component 4 atomizes and sprays the solvent into the sealed space 2.

[0034] It is worth mentioning that, such as Figure 1 As shown, the temperature control component is configured as an insulated cavity 3 that can accommodate the heat exchange medium, and the insulated cavity 3 keeps the sealed space 2 at a constant temperature.

[0035] It is worth mentioning that, such as Figure 1 As shown, the temperature control component can be set as an electric heating element. In this application, the electric heating element can be an electric heating plate. The electric heating plate is heated by heating methods such as electric heating wires. At the same time, the temperature of the electric heating plate is controlled by a temperature control device to keep the sealed space 2 at a constant temperature.

[0036] It is worth mentioning that, such as Figures 3 to 7 As shown, the insulation cavity 3 is fixedly equipped with a fixing plate 31, several heating tubes 32 fixedly mounted on the fixing plate 31, a water level gauge 33 fixedly mounted on the fixing plate 31, a water outlet pipe 34 fixedly mounted on the insulation cavity 3, a water pump 35 fixedly mounted on the water outlet pipe 34, a water inlet pipe 36 fixedly mounted on the water pump 35, a water outlet head 37 fixedly mounted on the water inlet pipe 36, a water filling pipe 38 fixedly mounted on the fixing plate 31, and a solenoid valve 39 fixedly mounted on the water filling pipe 38. The heating tubes 32 and the water level gauge 33 are all matched with the insulation cavity 3, and the water outlet pipe 34, the water filling pipe 38, and the water outlet head 37 are all connected to the insulation cavity 3. The water level gauge 33 and the solenoid valve 39 are electrically connected. The system is connected to a water source at one end of the water supply pipe 38. During use, after the heating pipe 32 heats the water, the upper part of the insulation cavity 3 contains hot water and the lower part contains cold water. Therefore, the water pump 35 draws cold water from the bottom of the insulation cavity 3 into the inlet pipe 36 through the outlet pipe 34, and then flows into the insulation cavity 3 from the outlet head 37, pushing the hot water downwards for circulation. The temperature of the water in the insulation cavity 3 keeps the sealed space 2 at a constant temperature. When the water level is lower than the set value, the water level gauge 33 transmits an electrical signal to the solenoid valve 39. After the solenoid valve 39 opens, water flows into the insulation cavity 3 through the water supply pipe 38 until the water level gauge 33 detects that the water level is reached and drives the solenoid valve 39 to open and close, achieving the effect of automatic water supply.

[0037] In addition, such as Figure 6 and Figure 8 As shown, the spray assembly 4 includes a pressurized tank 41 fixedly mounted on the frame 1, an inlet pipe 42 and an outlet pipe 43 fixedly mounted on the pressurized tank 41, a main pipe 44 fixedly mounted on the fixed plate 31, several branch pipes 45 fixedly mounted on the main pipe 44, spray heads 46 fixedly mounted at both ends of the branch pipes 45, an exhaust pipe 47 fixedly mounted on the fixed plate 31, and an air valve 48 fixedly mounted on the exhaust pipe 47. The exhaust pipe 47 is connected to the sealed space 2, and the outlet pipe 43 is connected to the main pipe 44. A solvent tank is connected to the inlet pipe 42, and the solvent in the solvent tank enters the pressurized tank 41 through the inlet pipe 42. A flow control valve is installed on the inlet pipe 42. A level gauge and an exhaust valve are installed on the pressurized tank 41, and a pressurization device is connected to the pressurized tank 41. The liquid head 46 is inclined on the branch pipe 45, and the included angle between the two is set within the range of 120°-150°. During use, when the pressure tank 41 needs to be replenished with solvent, the flow control valve is opened, and the solvent in the solvent tank flows into the pressure tank 41 through the liquid inlet pipe 42. At the same time, the exhaust valve discharges the gas in the pressure tank 41 until the liquid level gauge detects that the solvent has reached the required amount. Then, the exhaust valve is closed, and the pressurizing device pressurizes the pressure tank 41, causing the solvent to enter the main pipe 44, branch pipe 45 and the spray head 46 through the liquid outlet pipe 43 and be atomized and sprayed out. At the same time, the air valve 48 is opened, and the exhaust pipe 47 discharges the air in the upper part of the sealed space 2. The solvent is atomized and sprayed onto the heat preservation cavity 3 or the electric heating element and then vaporized, thus adhering to the plastic shell for brightening, which greatly improves the efficiency of brightening the surface of the plastic shell.

[0038] It needs to be emphasized that, such as Figure 3 As shown, a waste gas outlet 51 is provided on the fixed plate 31, and a waste gas pipe 52 is fixedly installed on the waste gas outlet 51. The waste gas outlet 51 is connected to the sealed space 2. A negative pressure device is connected to the waste gas pipe 52, and a valve is provided on the waste gas pipe 52. A drive device is provided on the frame 1. The drive device can drive the valve to open or close. In use, after the plastic shell in the sealed space 2 is illuminated, the drive device drives the valve to open. The negative pressure device draws the waste gas in the sealed space 2 into the environmental protection treatment device for treatment through the waste gas pipe 52 and the waste gas outlet 51. The waste gas is centrally treated to prevent pollution of the working environment and improve the safety factor of the staff.

[0039] It should be further explained that, such as Figure 5 As shown, the heat insulation cavity 3 is set on the bottom surface of the sealed space 2 and on the two sides connected to the bottom surface. The temperature inside the sealed space 2 is kept constant through the heat insulation cavity 3.

[0040] It is worth mentioning that, such as Figure 2 As shown, a conveying roller 6 is installed in the enclosed space 2, and the plastic shell is conveyed through the conveying roller 6.

[0041] Furthermore, such as Figure 2 As shown, sealing doors 7 are slidably installed on both sides of the sealed space 2, and sealing doors 7 are equipped with rubber strips. A door pull rod 8 is installed in the middle of the sealing door 7. Both sealing doors 7 are driven by a drive device to lift and lower. At the same time, cylinders are installed on both sides of the frame 1, and pull blocks are installed on the cylinders. When the plastic shell is transferred into the sealed space 2, the sealing doors 7 on both sides descend to seal, and the door pull rod 8 falls into the pull block. The cylinders apply a certain pulling force, which, together with the rubber strips, improves the sealing performance of the sealed space 2. In addition, after the plastic shell is brightened, one sealing door 7 is opened first, and the negative pressure device adsorbs the waste gas in the sealed space 2. Air enters the sealed space 2 from one side. After the adsorption time is set, the other sealing door 7 is opened to centrally treat the waste gas in the sealed space 2 and prevent the waste gas from flowing out of the sealed space 2.

[0042] In addition, such as Figure 7 As shown, the heat exchange medium in the insulation cavity 3 can be either water or oil, and the temperature range of the heat exchange medium is set between 55℃ and 60℃, which effectively vaporizes the material while ensuring that the plastic shell is not damaged.

[0043] Work process

[0044] Heating element 32 heats the water. The upper part of the insulation cavity 3 contains hot water, and the lower part contains cold water. Water pump 35 draws cold water from the bottom of the insulation cavity 3 through outlet pipe 34 into inlet pipe 36, and then flows into the insulation cavity 3 through outlet head 37, circulating the hot water downwards. The temperature of the water in the insulation cavity 3 keeps the sealed space 2 at a constant temperature. When the water level is lower than the set value, water level gauge 33 transmits an electrical signal to solenoid valve 39. After solenoid valve 39 opens, water flows into the insulation cavity 3 through water inlet pipe 38. The water level gauge 33 detects that the water level is high and drives solenoid valve 39 to open and close, achieving automatic water filling. After the plastic shell is transferred to the sealed space 2 by transfer roller 6, the sealing doors 7 on both sides descend to seal it. The flow control valve opens, and the solvent in the solvent tank flows into the liquid inlet pipe 4. 2. The solvent flows into the pressurizing tank 41, and at the same time, the exhaust valve discharges the gas in the pressurizing tank 41. After the liquid level gauge detects that the solvent has reached the required amount, the exhaust valve closes, and the pressurizing device pressurizes the pressurizing tank 41, so that the solvent enters the main pipe 44, branch pipe 45 and spray head 46 through the liquid outlet pipe 43 and is atomized and sprayed out. At the same time, the gas valve 48 is opened, and the exhaust pipe 47 discharges the air in the upper part of the sealed space 2. The solvent is atomized and sprayed onto the heat preservation cavity 3 and then vaporized, thus adhering to the plastic shell for brightening. After brightening is completed, one side of the sealing door 7 is opened first, and the negative pressure device adsorbs the waste gas in the sealed space 2. Air enters the sealed space 2 from one side. After the set adsorption time, the other side of the sealing door 7 is opened to centrally treat the waste gas in the sealed space 2 and prevent the waste gas from flowing out of the sealed space 2.
