The upper end of the first spring 506 is fixedly connected to the inner wall of the fixing frame 501. A limiting groove 507 is opened on the upper surface of the fixing frame 501.

The upper end of the clamping rod 509 is clamped inside the clamping groove 18.

[0030] By adopting the above technical solution, for the UV curing furnace used in the automatic spraying production line, by setting the fixing mechanism 5 and the clamping block 6, when people need to install the lamp holder, by squeezing the pressing block 502, the clamping rod 509 is inserted into the clamping groove 18 of the second clamping block 6, and then the pressing block 502 is released. Under the cooperation of the pressures of the first spring 506 and the second spring 510, the two groups of clamping rods 509 move in the opposite direction, so that the clamping rod 509 is clamped inside the clamping groove 18 for fixation. When disassembling, by squeezing the pressing block 502, under the cooperation of the sliding block 503 and the sliding groove 504, the connecting column 505 is forced to displace downward, so that the first spring 506 is squeezed and stressed. Under the cooperation of the first U-shaped block 511, the connecting rod 512, the second U-shaped block 513 and the fixed sliding rod 508, the two groups of clamping rods 509 move in the opposite direction, so that the clamping rod 509 is disengaged from the clamping groove 18, and the cross-bar lamp holder 4 is disengaged from the toothed guide frame 3, and then the lamp holder can be removed, so as to facilitate the disassembly and installation of the UV lamp tube 9 and the lamp holder, and facilitate maintenance and replacement.

[0031] Specifically, both ends of the cross-bar lamp holder 4 are fixedly connected with the first longitudinal lamp holders 7, the lower surface of the first longitudinal lamp holders 7 is fixedly connected with the second longitudinal lamp holders 8, and UV lamp tubes 9 are arranged on the sides of the cross-bar lamp holder 4, the first longitudinal lamp holders 7 and the second longitudinal lamp holders 8.

[0032] Specifically, a third spring 11 is fixedly connected to the right end inside the movable groove 2, the left end of the third spring 11 is fixedly connected to the right end of the toothed guide frame 3, and a guide groove 10 is fixedly connected to the upper surface of the UV lamp box 1, and the upper end of the toothed guide frame 3 is movably connected inside the guide groove 10.

[0034] Specifically, a mounting plate 13 is fixedly connected to the upper surface of the UV lamp box 1, a positive and negative motor 14 is fixedly connected to the upper surface inside the mounting plate 13, a disc cam 15 is fixedly connected to the lower end of the output shaft of the positive and negative motor 14, and the driven wheel 12 is arranged between the disc cam 15 and the driven wheel 12.

[0035] By adopting the above technical solution, for the UV curing furnace used in the automatic spraying production line, by setting the forward and reverse motor 14 and the driving disc cam 15, controlling the operation of the forward and reverse motor 14, driving the disc cam 15 to rotate, when gradually rotating to the high position of the disc cam 15, under the cooperation of the disc cam 15 and the driven wheel 12, the toothed guide frame 3 is forced to move and compress the third spring 11. When the disc cam 15 rotates and gradually rotates to the low position of the disc cam 15, the toothed guide frame 3 moves in the reverse direction under the elastic force of the third spring 11. Therefore, under the action of the forward and reverse motor 14 and the disc cam 15, etc., the toothed guide frame 3 drives the UV lamp tube 9 to perform a reciprocating linear motion in the conveying direction of the conveyor belt, achieving the purpose of changing the position of the UV lamp tube 9, avoiding that a certain part of the product is always in a high-intensity heating state, being beneficial to improving the uniformity of product heating, and improving the curing quality of the product.

[0036] Specifically, mounting holes 16 are provided on both sides of the UV lamp box 1.

[0037] Specifically, a production line conveyor belt passage 17 is provided at the lower end of the UV lamp box 1.

[0038] The working principle of the present utility model is as follows: In this solution, all electrical components are electrically connected to an external power supply through an external control switch. When people need to install the lamp holder, by squeezing the pressing block 502, the clamping rod 509 is inserted into the slot 18 of the second clamping block 6, and then the pressing block 502 is released. Under the combined action of the pressure of the first spring 506 and the second spring 510, the two groups of clamping rods 509 move in opposite directions, so that the clamping rod 509 is fixed inside the slot 18. When disassembling, by squeezing the pressing block 502, under the cooperation of the slider 503 and the chute 504, the connecting column 505 is forced to move downward, causing the first spring 506 to be squeezed and stressed. Under the cooperation of the first U-shaped block 511, the connecting rod 512, the second U-shaped block 513 and the fixed slide rod 508, the two groups of clamping rods 509 move in opposite directions, so that the clamping rod 509 disengages from the slot 18, and the cross-bar lamp holder 4 disengages from the toothed guide frame 3, and then the lamp holder can be removed, which is convenient for disassembling and installing the UV lamp tube 9 and the lamp holder, facilitating maintenance and replacement. It is fixed to the side of the automatic spraying production line through the mounting holes 16 on the side plate. The conveyor belt of the automatic spraying production line passes through the production line conveyor belt channel 17. The products that have completed automatic spraying in the previous process are input into the UV lamp box 1 by the conveyor belt. The forward and reverse motor 14 is controlled to act, driving the disk-shaped cam 15 to rotate. When it gradually rotates to the high position of the disk-shaped cam 15, under the cooperation of the disk-shaped cam 15 and the driven wheel 12, the toothed guide frame 3 is forced to move and compress the third spring 11. When the disk-shaped cam 15 rotates and gradually rotates to the low position of the disk-shaped cam 15, the toothed guide frame 3 moves in the reverse direction under the elastic force of the third spring 11. Therefore, under the action of the forward and reverse motor 14 and the disk-shaped cam 15, etc., the toothed guide frame 3 drives the UV lamp tube 9 to perform a reciprocating linear motion in the conveying direction of the conveyor belt, achieving the purpose of changing the position of the UV lamp tube 9, avoiding a certain part of the product being in a high-intensity heating state all the time, being beneficial to improving the uniformity of the product's heating, and improving the curing quality of the product.
