Detailed Implementation

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] like Figures 1-6As shown, an adjustable laser plate-making device for printing plate production includes a base 1, a support frame 2 fixedly connected to the back of the base 1, a connecting seat 3 fixedly connected to the front of the support frame 2, two symmetrically distributed frames 4 fixedly connected to the top of the base 1, an adjustment mechanism 5 provided on the base 1, and a moving mechanism 6 provided on the connecting seat 3.

[0030] The adjustment mechanism 5 includes a worm gear 51 that is rotatably connected to the inside of the base 1. Two first threaded rods 52 are rotatably connected to the inner bottom wall of the base 1, and worm wheels 53 are fixedly connected to the outer bottom of the two first threaded rods 52.

[0031] The moving mechanism 6 includes an electric push rod 61 fixedly installed on the right side of the connecting seat 3. The output shaft of the electric push rod 61 is fixedly connected to the housing 62. Two fixed rods 63 are symmetrically distributed between the left and right sides of the inner wall of the connecting seat 3.

[0032] It should be noted that the worm 51 and worm wheel 53 have self-locking properties, which increases the stability of the adjustment mechanism 5 during adjustment.

[0033] like Figures 1-3 As shown, the outer side of the worm 51 meshes with the outer side of the two worm wheels 53, and the outer side of the two first threaded rods 52 are threadedly connected to movable blocks 54. The two movable blocks 54 are fixedly connected to a housing 55 on opposite sides, and a clamping mechanism 56 is provided inside the housing 55.

[0034] It should be noted that rotating the worm gear 51 causes the two worm wheels 53 to rotate, which in turn drives the two first threaded rods 52. The two first threaded rods 52 then drive the two movable blocks 54 to move up and down simultaneously, thereby adjusting the height of the printing plate.

[0035] like Figures 1-4 As shown, the clamping mechanism 56 includes a second threaded rod 561 rotatably connected to the inner wall of the back of the cabin 55. A movable plate 562 is threadedly connected to the outer side of the second threaded rod 561. Positioning blocks 563 are fixedly connected to both the left and right sides of the movable plate 562. Positioning plates 564 are slidably connected to the outer sides of the two positioning blocks 563. Two symmetrically distributed positioning rods 565 are fixedly connected to the top of the two positioning plates 564. A U-shaped plate 566 is fixedly connected to one end of the two positioning rods 565 on the left and one end of the two positioning rods 565 on the right. A clamping assembly 567 is provided on each of the two U-shaped plates 566.

[0036] It should be noted that when the second threaded rod 561 is rotated, the second threaded rod 561 drives the movable plate 562 to move forward. The movable plate 562 drives the two positioning blocks 563 to slide inside the inclined surface of the positioning plate 564, thereby causing the two positioning plates 564 to move relative to each other. In turn, the positioning rod 565 drives the U-shaped plate 566 to move left and right, thereby clamping and fixing the printing plate.

[0037] like Figures 1-5 As shown, the top of the cabin 55 has two symmetrically distributed rectangular through holes, and the outer side of the positioning rod 565 is slidably connected to the inner wall of the rectangular through holes.

[0038] It should be noted that this facilitates the left and right movement of the positioning rod 565 and the U-shaped plate 566, thereby making it easier to clamp and fix printing plates of different sizes and increasing the versatility of the laser plate-making device.

[0039] like Figures 1-5 As shown, the clamping assembly 567 includes a bolt 5671 threadedly connected to the middle of the U-shaped plate 566. A clamping plate 5672 is rotatably connected to the bottom of the bolt 5671. Two symmetrically distributed guide rods 5673 are fixedly connected to the top of the clamping plate 5672. The outer side of the guide rods 5673 is slidably connected to the top of the U-shaped plate 566. A spring 5674 is sleeved on the outer side of each of the two guide rods 5673.

[0040] It should be noted that rotating the bolt 5671 causes the clamping plate 5672 to move downwards. By setting the guide rod 5673, the clamping plate 5672 is limited and supported, increasing the stability of the clamping plate 5672 during movement, thereby clamping and fixing the printing plate. At the same time, the spring 5674 extends and compresses the clamping plate 5672, increasing the stability of the clamping plate 5672 during clamping and fixing.

[0041] like Figures 1-5 As shown, an anti-slip pad is fixedly connected to the bottom of the clamping plate 5672.

[0042] It should be noted that this increases the stability of the clamping plate 5672 during clamping and fixing.

[0043] like Figures 1-6 As shown, the outer sides of the two fixed rods 63 are slidably connected to the inside of the housing 62. A motor 64 is fixedly installed on the inner wall of the back of the housing 62. A lead screw 65 is fixedly connected to the output shaft of the motor 64. A connecting block 66 is threadedly connected to the outer side of the lead screw 65. A connecting plate 67 is fixedly connected to the bottom of the connecting block 66. A laser 68 is fixedly installed at the bottom of the connecting plate 67.

[0044] The laser 68 used in this case can be a CO2 laser or a fiber laser, which are commonly used in the prior art.

[0045] It should be noted that when the electric push rod 61 is activated, the electric push rod 61 drives the housing 62 to slide left and right on the outside of the fixed rod 63, thereby adjusting the left and right position of the laser 68. When the motor 64 is activated, the output shaft of the motor 64 drives the lead screw 65 to rotate. The lead screw 65 drives the connecting block 66 to move back and forth. The connecting block 66 drives the connecting plate 67 to move back and forth. The connecting plate 67 drives the laser 68 to move back and forth, thereby improving the working efficiency of the laser plate making device.

[0046] The working principle of this utility model is as follows: When in use, the printing plate is placed between two U-shaped plates 566. Rotating the second threaded rod 561 causes the movable plate 562 to move forward. The movable plate 562 causes two positioning blocks 563 to slide inside the inclined surface of the positioning plate 564, thus causing the two positioning plates 564 to move relative to each other. This, in turn, causes the U-shaped plates 566 to move left and right via the positioning rod 565, thereby clamping and fixing the printing plate. Rotating the bolt 5671 causes the clamping plate 5672 to move downward. The guide rod 5673 provides limiting support for the clamping plate 5672, increasing its stability during movement and thus clamping and fixing the printing plate. Simultaneously, the spring 5674 extends and compresses the clamping plate 5672, increasing its stability. To improve the stability of the clamping plate 5672 during clamping and fixing, the worm gear 51 is rotated, which drives the two worm wheels 53 to rotate. The two worm wheels 53 drive the two first threaded rods 52, which in turn drive the two movable blocks 54 to move up and down simultaneously, thereby adjusting the height of the printing plate. The laser 68 is then activated to engrave the printing plate. The electric push rod 61 is activated, which drives the housing 62 to slide left and right on the outside of the fixed rod 63, thereby adjusting the left and right position of the laser 68. The motor 64 is then activated, and the output shaft of the motor 64 drives the lead screw 65 to rotate. The lead screw 65 drives the connecting block 66 to move back and forth, which in turn drives the connecting plate 67 to move back and forth. The connecting plate 67 then drives the laser 68 to move back and forth, thus improving the working efficiency of the laser plate-making device.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
