During the movement, the scraper block 205 is used to scrape and suck away the excess slurry inside the lamp tube, wherein the distance between the lower surface of the scraper block 205 and the inner wall of the lamp tube is the thickness of the slurry layer (also called frosted layer, white coating layer).

[0040] The scraper block 205 is provided with an arc-shaped scraper portion 205a and a slurry flow groove 205b; the arc-shaped scraper portion 205a is used to guide the slurry to the slurry flow groove 205b, so as to facilitate the suction port 205c to suck away.

[0041] The scraping block 205 is set to be circular, so that the slurry can be scraped off the entire lamp tube without waiting for the slurry to settle.

[0042] The first protective cover 7, the second protective cover 10, the suction tube 204 and the scraper block 205 all have a coating that prevents the slurry from sticking.

[0043] The power assembly includes a guide rail 211, a moving block 212, a connecting plate 213 and a guide plate 214; two guide rails 211 distributed front and back are installed on the inner wall of the operation box 201; the two guide rails 211 are fixedly connected to a connecting plate 213; the connecting plate 213 is fixedly connected to the left end of the straw 204; the right side wall of the operation box 201 is fixedly connected to a guide plate 214 adapted to the number of the first protective cover 7 and the second protective cover 10; a plurality of guide wheels are arranged on the guide plate 214.

[0044] The working of the above embodiment is: manually or with external equipment, the lamp tubes are placed on the conveying assembly in order, and then the second electric push rod 8 is controlled to push the second connecting ring 9 and the second protective cover 10 to move to the right, and the second protective cover 10 is sleeved on the left end of the lamp tube, see the figure, at this time, the wiping part 10a is located inside the lamp tube and contacts with its inner wall, and at the same time, the first electric push rod 5 is controlled to push the first connecting ring 6 and the first protective cover 7 to move to the left, and the first protective cover 7 is sleeved on the right part of the lamp tube, see the figure, at this time, the right part of the lamp tube is stuck in the groove 7a, thus completing the protection of both ends of the lamp tube.

[0045] Then, the spraying assembly is controlled to inject slurry greater than half of the capacity of the lamp tube from the through hole of the first protective cover 7 into the lamp tube. At this time, the left part of the second protective cover 10 cooperates with the suction pipe 204 to form a seal, and the through hole of the first protective cover 7 is sealed by the spraying assembly. At the same time, the lamp tube is rotated by the conveying assembly and the rotating uniform assembly, so that the slurry is fully adhered in the lamp tube, so that the slurry can adhere to the inner wall of the lamp tube. After the slurry spraying is completed, the excess slurry is sucked away by the spraying assembly, but some slurry will still remain. The lamp tube is controlled to stop rotating and then stand still. After a period of time, due to the horizontal placement of the lamp tube, the slurry remains at the bottom of the lamp tube. Afterwards, the moving block 212 is controlled to move rightward on the guide rail 211, and then the connecting plate 213 is driven to move rightward. At the same time, the suction tube 204 and the slurry scraping block 205 are driven to move rightward. The slurry scraping block 205 moves rightward through two arc-shaped scraping parts 205a to collect the slurry at the slurry flow groove 205b. At the same time, the suction pump 202 works to suck the slurry from the suction port 205c and the telescopic tube 203 of the suction tube 204 into its storage component, and then the suction tube 204 is controlled to return to the left. Figure 8 The lamp tube is in the state shown, and then the lamp tube is controlled to continue to rotate. At this time, the wiping part 10a will wipe off the slurry at the left end of the lamp tube, and the right end of the lamp tube is protected by the groove 7a. In this way, finished lamp tubes with a slurry layer sprayed inside and no slurry inside both ends are obtained in batches. Compared with the prior art, the present invention can achieve uniform slurry spraying inside the lamp tube, without the need to vertically place the lamp tube that has been transported horizontally, and without the need to wipe off the slurry at both ends after spraying the slurry, and the overall equipment occupies a small area.

[0046] It should be noted that when the straw 204 moves to the left or right, the telescopic tube 203 adapts to the telescopic movement, and the straw 204 slides on the guide plate 214 .

[0052] On the basis of the above embodiment, the lamp tubes are placed in the placement groove 4b in an orderly manner. When the lamp tubes need to be rotated, the conveyor belt 302 is driven downward by the third electric push rod 301, and the conveyor belt 302 contacts the upper part of the lamp tube. When the conveyor belt 302 rotates, it drives the lamp tube to rotate in the placement groove 4b of the transport rack 4, and the rotating wheel 4a cooperates to rotate.
