Description

Technical Field

[0001] The utility model relates to the technical field of printing, in particular to a printing dot structure based on high-screen mixed screening. Background Art

[0002] During the printing process, continuous tone images must be converted into halftone images through screening before printing can be completed. Different sizes of dots are opened in the middle of the screen. The dot is the smallest unit that represents the level of the printed image. The shape, angle and size of the dot will directly affect the printing quality.

[0003] In the prior art, multiple screens are usually arranged and combined using bolts. Although printing work can be completed, there are still some shortcomings. When the order of multiple screens needs to be replaced and rearranged, employees need to use tools and rotate the bolts multiple times to disassemble the screens. After the arrangement or replacement is completed, tools are also needed to rotate the bolts multiple times, which is cumbersome and increases the labor intensity of employees. At the same time, it takes a long time to replace the screens, which reduces the printing efficiency. Therefore, a printing dot structure based on high-screen mixed screening is proposed to solve the above problems. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a printing dot structure based on high-line mixed screening, aiming to improve the problem that the prior art requires employees to use tools and rotate the bolts multiple times to complete the installation and disassembly of the screen, which is more cumbersome and increases the labor intensity of employees. At the same time, it takes a long time to replace the screen, thereby reducing the efficiency of printing.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a printing dot structure based on high-screen mixed screening, comprising a frame, a screen group is slidably connected to the middle of the frame, a placement slot is opened in the middle of the frame, a movable plate is rotatably connected to the middle of the frame, the movable plate is arranged in the middle of the placement slot, a compression spring is fixedly connected to the inside of the frame, a clamping block is fixedly connected to the other end of the compression spring, the clamping block is in contact with the movable plate, a clamping slot is opened in the middle of the movable plate, the clamping block and the clamping slot are plugged and matched, and a disassembly component is slidably connected to the middle of the frame;

[0006] Through the above technical solution, the movable plate can be flipped and the card block can be squeezed when the movable plate moves, so that the card block can compress the compression spring. When the card slot moves to the original position of the card block, the card block can be bounced into the card slot through the compression spring, and then the movable plate can be fixed. At this time, the mesh panel group can be restricted to prevent the mesh panel group and the frame from separating.

[0007] Further, the disassembly assembly includes a pull rod, the pull rod is slidably connected to the middle part of the frame, and one end of the pull rod close to the frame is fixedly connected to one side of the clamping block close to the compression spring;

[0008] Through the above technical solution, the card block and the card slot can be separated by pulling the pull rod. At this time, the screen plate group can be quickly taken out by flipping the movable plate in the opposite direction. At this time, the screen plate group can be replaced or the order of the screen plate group can be changed, which reduces the labor intensity of employees and effectively improves the printing efficiency.

[0009] Further, a rotating disk is rotatably connected to the middle of the frame, a spring is fixedly connected to the outside of the rotating disk, the other end of the spring is fixedly connected to the inside of the frame, a connecting plate is rotatably connected to the outside of the rotating disk, a slider is rotatably connected to the other side of the connecting plate, a pressure plate is fixedly connected to the other side of the slider, and the pressure plate is in contact with the mesh plate group;

[0010] Through the above technical solution, when the mesh panel group enters the frame, the pressure plate will be squeezed by the mesh panel group, and then can move simultaneously with the slider. When the slider moves, the turntable can be rotated through the connecting plate. When the turntable rotates, the clockwork spring can be twisted and compressed. At this time, the mesh panel group can be installed after the mesh panel group is completed to ensure the sealing between the mesh panel groups.

[0011] Furthermore, a positioning groove is provided in the middle of the frame, and the movable plate is plugged into and matched with the positioning groove;

[0012] With the above technical solution, the positioning groove can be used to allow the movable plate to enter the positioning groove and contact with the clamping block, thereby completing the fixation of the movable plate.

[0013] Furthermore, a partition is slidably connected inside the frame, and the partition is fixedly connected between the compression spring and the clamping block;

[0014] Through the above technical solution, the block can be restricted by the partition, thereby preventing the compression spring from being deformed and damaged due to tilting and squeezing, thereby increasing the service life of the compression spring.

[0015] Furthermore, one end of the pull rod away from the frame is fixedly connected with a pull ring;

[0016] Through the above technical solution, the pull rod can be pulled more conveniently through the pull ring.

[0017] Furthermore, a handle is fixedly connected to a side of the turntable away from the clockwork spring, and an anti-slip groove is provided on the outer side of the handle;

[0018] Through the above technical solution, the turntable can be rotated more effectively and comfortably under the action of the handle and the anti-slip groove.

[0019] Furthermore, a slide groove is provided in the middle of the frame, and the slider is slidably connected to the middle of the slide groove;

[0020] Through the above technical solution, the slider can be limited by the sliding groove, so that the pressure plate can only move vertically, which can prevent the slider from tilting and causing the pressure plate to be unable to move.

[0021] The utility model has the following beneficial effects:

[0022] 1. In the utility model, after the screen plate group enters the frame, the movable plate is flipped and pressed against the card block, so that the card block can compress the compression spring. When the card slot moves to the original position of the card block, the card block can be bounced into the card slot under the action of the compression spring, so that the screen plate group can be confined in the frame. The screen plate group can be taken out for replacement or the order of the screen plate group can be rearranged by pulling the pull rod. There is no need for employees to use tools to assemble and disassemble the screen plates, thereby reducing the labor intensity of employees and improving printing efficiency.

[0023] 2. In the utility model, when the screen plate group enters the frame, the screen plate group will squeeze the two pressure plates, and then the two pressure plates can drive the two sliders to move away from each other. At this time, under the action of the connecting plate, the turntable can twist and compress the clockwork spring. When the screen plate assembly is installed, the two pressure plates can squeeze the screen plate group under the action of the clockwork spring, so that the screen plate groups can fit each other, thereby improving the printing quality.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1-Figure 3 The utility model provides an embodiment: a printing dot structure based on high-screen mixed screening, including a frame 1, a screen group 2 is slidably connected to the middle of the frame 1, a placement slot 3 is provided in the middle of the frame 1, a movable plate 4 is rotatably connected to the middle of the frame 1, and the movable plate 4 is arranged in the middle of the placement slot 3. A compression spring 5 is fixedly connected to the inside of the frame 1, and a card block 6 is fixedly connected to the other end of the compression spring 5, and the card block 6 is in contact with the movable plate 4. A card slot 7 is provided in the middle of the movable plate 4, and the card block 6 and the card slot 7 are plugged and matched. A fixed spring 5 is provided in the middle of the frame 1. The positioning groove 14 is plugged into and matched with the movable plate 4. The positioning groove 14 can limit the movable plate 4, so that the movable plate 4 can contact the block 6 when the movable plate 4 is flipped. When the movable plate 4 and the block 6 are in contact, the block 6 will be squeezed and moved. When the block 6 moves, the compression spring 5 can be compressed. When the slot 7 moves to the original position of the block 6 and the block 6 is not squeezed by external force, the block 6 can be bounced into the slot 7 by the compression spring 5, and then the movable plate 4 can be fixed. At this time, the mesh panel group 2 can be restricted to prevent the mesh panel group 2 from separating from the frame 1.

[0033] Reference Figure 1-Figure 3The frame 1 is internally slidably connected with a partition 15, which is fixedly connected between the compression spring 5 and the block 6. The block 6 can be restricted by the partition 15, thereby preventing the block 6 from tilting when moving, thereby avoiding the compression spring 5 from being deformed and damaged by tilting and squeezing, and improving the service life of the compression spring 5. A disassembly component is slidably connected to the middle part of the frame 1, and the disassembly component includes a pull rod 8, which is slidably connected to the middle part of the frame 1, and one end of the pull rod 8 close to the frame 1 is fixedly connected to the side of the block 6 close to the compression spring 5. The block 6 can be pulled out from the middle of the slot 7 by pulling the pull rod 8, thereby releasing the fixation of the movable plate 4. At this time, the restriction on the screen group 2 can be released by flipping the movable plate 4 in the opposite direction, thereby quickly taking out the screen group 2 for replacement or changing the order of the screen group 2, while reducing the labor intensity of employees and effectively improving the printing efficiency. The pull rod 8 is fixedly connected to the end away from the frame 1 with a pull ring, and the pull rod 8 can be pulled more conveniently through the pull ring.

[0034] Reference Figure 4 and Figure 5 The middle part of the frame 1 is rotatably connected with a turntable 9, and a spring 10 is fixedly connected to the outer side of the turntable 9. The other end of the spring 10 is fixedly connected to the inside of the frame 1. The outer side of the turntable 9 is rotatably connected with a connecting plate 11, and the other side of the connecting plate 11 is rotatably connected with a slider 12, and the other side of the slider 12 is fixedly connected with a pressing plate 13, and the pressing plate 13 is in contact with the screen group 2. A slide groove 16 is provided in the middle part of the frame 1, and the slider 12 is slidably connected to the middle part of the slide groove 16. The slider 12 can be limited by the slide groove 16, and then the pressing plate 13 can be squeezed by the screen group 2 to enable vertical movement. At the same time, when the slider 12 moves, the turntable 9 can be rotated under the action of the connecting plate 11, and the spring 10 can be twisted and compressed when the turntable 9 rotates. Under the action of the spring 10, the two pressing plates 13 can continue to squeeze the screen group 2, so that the contact between the screen groups 2 can be ensured after the screen group 2 is installed, thereby improving the printing quality.

[0035] Reference Figure 4 and Figure 5 By rotating the turntable 9 and under the action of the connecting plate 11, the slider 12 can drive the pressure plate 13 to move away from each other, thereby releasing the restriction on the mesh group 2, and improving the efficiency of taking out the mesh group 2. A handle is fixedly connected to the side of the turntable 9 away from the clockwork spring 10, and an anti-slip groove is provided on the outside of the handle. The turntable 9 can be rotated more effectively and comfortably under the action of the handle and the anti-slip groove.

[0036] Working principle: When in use, after the mesh panel group 2 is placed in the frame 1, the movable plate 4 is flipped over, and when the movable plate 4 is flipped over, the card block 6 is squeezed, so that the card block 6 can compress the compression spring 5. When the card slot 7 moves to the original position of the card block 6, the card block 6 can be bounced into the card slot 7 under the action of the compression spring 5, so that the movable plate 4 can be restricted. At this time, the mesh panel group 2 can be prevented from being separated from the frame 1. The card block 6 and the card slot 7 can be separated by pulling the pull rod 8. At this time, the movable plate 4 can be flipped over and the restriction on the mesh panel group 2 can be released. The mesh panel group 2 can be taken out for replacement or the order of the mesh panel group 2 can be rearranged;

[0037] Among them, when the screen group 2 enters the frame 1, the screen group 2 will squeeze the two pressure plates 13, so that the two pressure plates 13 can drive the two sliders 12 to move away from each other. At this time, the turntable 9 can be rotated under the action of the connecting plate 11. When the turntable 9 rotates, the clockwork spring 10 can be twisted and compressed. At the same time, the clockwork spring 10 can provide a force to reset the turntable 9, so that the two pressure plates 13 can squeeze the screen group 2, so that the screen groups 2 can fit each other, thereby improving the printing quality.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
