Description

Technical Field

[0001] The utility model relates to the field of UV light curing machines, in particular to an ultraviolet light curing machine with a light-shielding function. Background Art

[0002] UV curing machines are mechanical devices that emit strong ultraviolet rays and are widely used in the printing, electronics, building materials, machinery and other industries. The working principle of this device is to irradiate special glue with ultraviolet rays, causing the glue to polymerize and solidify.

[0003] Chinese Patent Publication No. CN213558199U discloses a UV curing machine with a light-shielding function, comprising a UV curing machine and a light-shielding strip. A fixing rod is slidably connected to the inner side of the upper end of the light-shielding strip, and a first spring is slidably connected to the outer side of the fixing rod. The left end of the first spring is fixedly connected to the UV curing machine. The fixing rod passes through the UV curing machine and the light-shielding strip, and the fixing rod is slidably connected to the UV curing machine and the light-shielding strip. In this UV curing machine, a fixing rod is provided. This arrangement cooperates with the sliding connection between the fixing rod and the first spring, the fixed connection between the first spring and the UV curing machine, and the sliding connection between the fixing rod and the light-shielding strip. When replacing the light-shielding strip, one only needs to pull the fixing rod to the left, align the light-shielding strip with the groove at the corresponding position of the UV curing machine, and then release the fixing rod. The fixing rod passes through the light-shielding strip and enters the UV curing machine to complete the replacement. This simple replacement method can be quickly replaced, saving time and effort.

[0004] However, the above technical solution has the following shortcomings: when the light-shielding belt is in use, there is still a gap between the bottom of the light-shielding belt and the conveyor belt, which causes ultraviolet rays to escape, and when the workpiece enters the interior of the machine body, it will rub against the light-shielding belt, which not only reduces the service life of the light-shielding belt, but also the part that contacts the workpiece will be affected in terms of wettability, which may affect the effect of the photocuring treatment.

DETAILED DESCRIPTION

[0022] Example 1

[0023] like Figure 1-Figure 5As shown, the embodiment proposes an ultraviolet UV curing machine with a shading function, comprising a conveying seat 1 and a shell 2; the shell 2 is arranged on the conveying seat 1, and comprises a through frame 5 arranged on the side of the shell 2 and a working chamber for light curing processing, a feeding channel is arranged inside the through frame 5, and a shading device is arranged at the entrance of the through frame 5, the shading device comprises a shading component, a driving component for driving the shading component to move vertically and a fixing component for disassembling and replacing the shading component, the shading component comprises a shading plate 6 located at the entrance of the through frame 5, and a shading strip 7 attached to the lower surface of the shading plate 6, so as to And a connecting block 8 for connecting the sunshade 6 and the sunshade strip 7, a horizontal slide groove 9 is provided inside the sunshade 6, one end of the slide groove 9 passes through the sunshade 6, the sunshade strip 7 is made of elastic material to reduce wear on the bottom, the sunshade strip 7 is set on the connecting block 8, and the connecting block 8 is slidably set in the slide groove 9, the cross-sectional shape of the slide groove 9 is T-shaped, the shape of the connecting block 8 is adapted to the slide groove 9, and a handle 15 for pushing and pulling the connecting block 8 is provided on the connecting block 8, and the handle 15 is provided with stripes to increase the friction during gripping to avoid falling due to the length of the connecting block 8 being too long and difficult to hold.

[0024] The driving assembly includes a first motor 17 arranged on the conveying seat 1, a first gear 18 driven by the first motor 17, a threaded rod 19 rotatably arranged on the conveying seat 1, a second gear 20 coaxially arranged on the threaded rod 19, two fixed blocks 16 distributed on the left and right sides of the light shielding plate 6, two support frames 21 distributed on the left and right sides of the through frame 5, and a guide structure for moving the light shielding plate 6. The first gear 18 and the second gear 20 are meshed and connected, the left fixed block 16 is threadedly connected to the threaded rod 19, and the top of the threaded rod 19 is rotatably connected to the support frame 21. The guide structure includes a guide rod 22 vertically arranged on the conveying seat 1, the top of the guide rod 22 is fixedly connected to the right support frame 21, and the right fixed block 16 is slidably arranged on the guide rod 22.

[0025] The fixing assembly includes a fixing frame 10 arranged on the sunshade 6, a rod 11 sliding horizontally on the fixing frame 10, a convex ring 12 coaxially arranged on the rod 11 and a spring 13 sleeved on the rod 11, the two ends of the spring 13 are respectively in contact with the fixing frame 10 and the convex ring 12, and a positioning hole 14 for the rod 11 to be inserted is provided on the connecting block 8.

Under the guiding action of the guide rod 22, the left fixed block 16 is screwed with the threaded rod 19, and then the fixed block 16 drives the light shielding plate 6 to move upward until the light shielding plate 6 opens the entrance of the feeding channel. When the workpiece enters the shell 2, the first motor 17 drives the first gear 18 to reverse, so that the light shielding plate 6 drops to the lowest point. At this time, the light shielding bar 7 is just in contact with the conveyor belt 26, so that the light shielding plate 6 shields the ultraviolet rays for the second time, and the light shielding bar 7 further blocks the gap between the light shielding plate 6 and the conveyor belt 26 to avoid a small amount of light reflection caused by diffuse reflection of ultraviolet rays. At the same time, it also avoids directly hanging the light shielding bar 7 at the entrance. The workpiece will contact the light shielding bar 7, which will not only easily wear the light shielding bar 7 and reduce the service life of the light shielding bar 7, but also the contact part of the light shielding bar 7 with the workpiece may be affected in wettability, thereby affecting the effect of light curing.

Under the action of the spring 13, the rod 11 passes through the positioning hole 14, and the replacement operation is realized, which is simple and convenient.

The edge of the conveyor belt 26 is in contact with the inner wall of the conveying seat 1 to reduce the gap for ultraviolet light leakage.

[0030] In this embodiment, the second motor 24 drives the active roller 25 to rotate, and with the action of the driven roller 27, the conveyor belt 26 transports the placed workpiece until it is transported to the processing position. When the processing is completed, the second motor 24 reverses and then transports the workpiece out of the working bin.
