[0031] See also Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9The outer shielding frame 206 at one end is equipped with an inner stabilizing plate 209, and the other end of the inner stabilizing plate 209 is inserted into the corresponding groove of the outer shielding frame 206 at the other end; the front and rear ends of the bottom of the bottom frame 2 are both equipped with bottom plates 207, and a sliding rod 208 is installed between the front and rear end bottom plates 207. The front and rear ends on the sliding rod 208 are slidably connected with a slider 211, and the other end of the slider 211 is installed at the bottom of the corresponding inner sleeve block 204; the outer shielding frame 206 is L-shaped, and the plate exposure area 102 is arranged between the inner stabilizing plate 209 and the bottom frame 2; the inner side wall of the inner stabilizing plate 209 is glued with a corresponding inner protective layer 210, and the inner protective layer 210 is designed with rubber material; when the two sets of outer shielding frames 206 move away from each other, one set of outer shielding frames 206 is equipped with an inner stabilizing plate 2 in the groove toward the outer end 09, drives the inner stabilizing plate 209 to move inside the other set of outer shielding frames 206 to ensure the stability of the connection and avoid the spacing problem when the connection surfaces of the two sets of outer shielding frames 206 move away from each other to a certain distance; because the slider 211 is slidably connected to the slide bar 208, the slide bar 208 is connected to the inner end of the two sets of bottom plates 207, and the slider 211 is connected to the inner sleeve block 204, when the inner sleeve block 204 moves, it can drive the slider 211 to slide in the same direction on the slide bar 208, thereby ensuring the stability of the inner sleeve block 204 when moving; when the product is in the feeding area 101 during plate making, its bottom is against the connection surface of the two sets of outer shielding frames 206, and the side of the outer shielding frame 206 that contacts the product is glued with an inner protective layer 210 made of rubber material to protect the contact surface.

[0032] See also Figure 2 and Figure 10A connecting assembly is provided between the bottom frame 2 and the printing plate exposure machine body 1, and the connecting assembly includes a connecting plate 3, which is installed at the front and rear ends of the outer wall of the printing plate exposure machine body 1.

When the cam 303 is in the unlock state, the spring 305 between the movable plate 301 and the slot 304 is stretched, so that the cam 303 is pulled out of the locking state inside the inner slot 302, and the fixation on the bottom plate 207 can be released. The bottom frame 2 can be pulled out of the inner slot 201 as a whole, so that the bottom frame 2 is separated from the printing plate exposure machine body 1 to realize the disassembly operation.

[0033] Working principle: The current traditional printing plate exposure machine is composed of a printing plate exposure machine body 1, a feeding area 101 and an exposure area 102. At this time, symmetrical outer shielding frames 206 are provided at the front and rear ends of the feeding area 101, and the outer shielding frame 206 is on the bottom frame 2. If the rotating handle 203 is rotated, the reverse threaded rod 202 connected thereto is driven to rotate inside the bottom frame 2. Since the inner sleeve block 204 is threadedly connected to the front and rear ends of the reverse threaded rod 202 and is connected to the outer shielding frame 206 by a movable rod 205, when the reverse threaded rod 202 rotates, the two groups of inner sleeve blocks 204 are driven to move away from or closer to each other's end, so that the outer shielding frame 206 moves in the same direction, and the distance between the two groups of outer shielding frames 206 is adjusted. According to needs, when exposing the plate, it can be restricted and positioned on the feeding area 101 by adjusting it to a suitable range to block the outer end of the product and prevent the risk of slipping.

[0034] When the opening on the movable plate 301 is pulled away from the end of the connecting plate 3 to drive the connecting plate 3 to move, the spring 305 set between the movable plate 301 and the card slot 304 is stretched to pull the card rod 303 out of the locked state inside the inner card slot 302, and the fixation on the bottom plate 207 can be released. The bottom plate 207 is connected to the bottom of the bottom frame 2. When the front and rear end bottom plates 207 are released, the bottom frame 2 is pulled out as a whole to move it out of the inner slot 201 to separate the bottom frame 2 from the printing platemaking machine body 1 and realize the disassembly operation. The above is the working process of the entire device, and the contents not described in detail in this manual belong to the existing technology known to professional and technical personnel in this field.
