DETAILED DESCRIPTION

[0021] To make the objectives, technical solutions, and advantages of the present application clearer, the present application will be further described in detail below with reference to specific embodiments and drawings. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] Some embodiments of the present application will be described below with reference to the drawings,

[0023] Embodiment 1

[0024] In combination with Figures 1-5 As shown in the drawings, the present embodiment provides a photocuring drying device of a printing machine, which comprises a main body mechanism 100.

[0025] The main body mechanism 100 comprises a support 110, an arc-shaped shell 120 arranged on one side of the support 110, an adjusting rod 130 arranged through the support 110 and rotationally connected to the arc-shaped shell 120 at the bottom end, round rods 140 symmetrically fixed on both sides of the arc-shaped shell 120 and movably arranged through the support 110, UV lamps 150 fixed on the inner wall of the arc-shaped shell 120 in a ring array, a diffusion film 160 fixed on the inner wall of the arc-shaped shell 120, photoelectric sensors 170 symmetrically mounted on both sides of the arc-shaped shell 120, and a central control assembly 180 mounted on the top end of the support 110.

[0026] The support 110 is used for mounting other components, the support 110 is in a U shape, both ends of the support 110 are fixed on a conveying belt through bolts, a threaded hole 111 is formed in the middle of the support 110, the adjusting rod 130 comprises a threaded rod 131 arranged through the threaded hole 111 and intermeshed with the threaded hole 111, and a knob 132 fixed on the top end of the threaded rod 131, the bottom end of the threaded rod 131 is rotationally connected to the arc-shaped shell 120, the threaded rod 131 is rotated in the threaded hole 111 by rotating the knob 132, the threaded rod 131 is driven to move up and down, that is, the entire arc-shaped shell 120 is driven to move up and down, and the distance between the bottom end of the arc-shaped shell 120 and the surface of the conveying belt is adjusted.

[0027] Round holes 112 are symmetrically formed in the top end of the support 110, the round rods 140 are movably arranged through the round holes 112, the movement of the arc-shaped shell 120 is limited, and the stability of the arc-shaped shell 120 during the up and down movement is ensured.

[0028] The arc-shaped shell 120 is semicircular in cross section, and the UV lamp 150 is arranged in an annular array on the inner wall of the arc-shaped shell 120, so that 180-degree UV light irradiation can be achieved, facilitating uniform drying of the printing coating on the surface of different special-shaped products, and the diffusion film 160 makes the UV light irradiation more uniform, improving the drying effect.

[0029] The photoelectric sensor 170 is installed on both sides of the arc-shaped shell 120 and can record the time when the printed matter is sent into and out of the arc-shaped shell 120. The photoelectric sensor 170 includes a transmitting end 171 installed on one side of the arc-shaped shell 120 and a receiving end 172 installed on the other side of the arc-shaped shell 120, which correspond to each other. The working principle is that the transmitting end 171 emits a beam of laser light, and the receiving end 172 receives it. When the printed matter is arranged between the two, the laser light is blocked by the printed matter. At this time, the receiver cannot receive the laser light, and it can be judged that the printed matter has passed.

[0030] The central control assembly 180 includes a shell 181 fixed to the top end of the support 110, a timer 182 installed on the inner wall of the shell 181, and a display screen 183 installed in the inner cavity of the shell 181 and extending out of the shell 181. The shell 181 is used to install the timer 182 and the display screen 183. The timer 182 is used to record the time when the printed matter passes through the inner cavity of the arc-shaped shell 120. Before the printed matter enters the arc-shaped shell 120, the photoelectric sensor 170 on one side of the arc-shaped shell 120 detects the printed matter and starts the timer 182. When the printed matter is completely sent out of the shell, the photoelectric sensor 170 on the other side of the arc-shaped shell 120 detects the printed matter and stops the timer 182. At this time, the timer 182 transmits the time to the display screen 183 for display, which is the drying time of the printed matter.

[0031] The working principle and use process of the utility model are as follows: when in use, the support 110 is installed on the conveyor belt, the conveyor belt is started, and the printed matter is driven into the inner cavity of the arc-shaped shell 120. Before entering the arc-shaped shell 120, the photoelectric sensor 170 on one side of the arc-shaped shell 120 detects the printed matter and starts the timer 182. After the printed matter enters the arc-shaped shell 120, the UV lamp 150 is started, and the UV light generated after passing through the diffusion film 160 irradiates the coating on the printed matter, making it dry and solidify quickly. Then, the printed matter moves with the conveyor belt and is sent out from the other side of the arc-shaped shell 120. When the printed matter is completely sent out of the shell, the photoelectric sensor 170 on the other side of the arc-shaped shell 120 detects the printed matter and stops the timer 182. At this time, the timer 182 transmits the time to the display screen 183 for display, which is the drying time of the printed matter.

[0032] Although the embodiments of the utility model have been shown and described, those skilled in the art can understand that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and purposes of the utility model, and the scope of the utility model is defined by the claims and their equivalents.
