Abstract
Description
Technical Field
[0001] This utility model relates to the field of flexible plate printing base film production technology, and in particular to an edge trimming device for flexible plate printing base film production. Background Technology
[0002] Flexographic printing, also known as offset printing, is a type of letterpress printing that uses a flexible printing plate and an anilox roller to transfer ink. The image areas of the flexographic plate are raised. During printing, the anilox roller evenly applies a layer of ink of a certain thickness to the image areas of the plate. Then, under the pressure of the impression cylinder, the ink layer of the image areas is transferred to the surface of the substrate, forming a clear image. The inking mechanism of a flexographic printing press is typically a two-roller inking mechanism.
[0003] Currently, some existing edge-cutting devices for flexographic printing base film production use winding rollers to collect the cut waste material, which facilitates unified processing by personnel. However, the winding collection width of these winding rollers cannot be adjusted, which causes relatively thin waste material to deviate when wound on the surface of the winding rollers. As a result, the waste material cannot be wound into a complete roll, making it inconvenient for personnel to process the waste roll later. Therefore, we propose an edge-cutting device for flexographic printing base film production to solve or improve the above problems. Utility Model Content
[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an edge-cutting device for the production of flexographic printing base film, which can effectively solve the problems of the existing technology.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model relates to a trimming device for producing flexible plate printing base film, comprising a device housing, a fixing column fixed to the surface of the device housing, an adjusting plate slidably mounted inside the fixing column via a slider, a drive motor fixed to the surface of the adjusting plate, a winding roller fixed to the top of the output shaft of the drive motor, a limiting ring sleeved on the surface of the winding roller, a connecting ring rotatably mounted on the surface of the limiting ring via a bearing, a first threaded rod rotatably mounted inside the winding roller via a bearing, a limiting plate fixed to the surface of the connecting ring, a second mounting block slidably mounted inside the adjusting plate, a second spring fixed to the top of the second mounting block, and a multi-segment telescopic rod fixed to the surface of the second mounting block.
[0007] Furthermore, the cutting blade is mounted on the surface of the adjusting plate, and the second auxiliary wheel is rotatably mounted on the surface of the adjusting plate via a rotating shaft. The second auxiliary wheel is located on one side of the cutting blade.
[0008] Furthermore, a first mounting block is slidably installed inside the adjusting plate, and a first auxiliary wheel is rotatably mounted on the surface of the first mounting block via a rotating shaft.
[0009] Furthermore, a first spring is fixed to the top of the first mounting block, with one end of the first spring fixed to the surface of the first mounting block and the other end fixed to the surface of the adjusting plate.
[0010] Furthermore, a second threaded rod is rotatably mounted inside the fixed column via a bearing. The second threaded rod passes through the slider of the adjusting plate and is threadedly connected to it.
[0011] Furthermore, one end of the multi-segment telescopic rod is fixed to the surface of the second mounting block, while the other end is slidably mounted inside the limiting plate via a slider.
[0012] This utility model has the following beneficial effects:
[0013] This invention, by setting a first threaded rod and a limiting ring, allows the position of the limiting ring to be adjusted when the first threaded rod is rotated, thereby changing the winding and collecting width on the surface of the winding roller.

It is relatively convenient to use. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0022] Please see Figure 1-5As shown, this utility model is a trimming device for producing flexible printing base film, including a device housing 1, a fixed column 2 fixed to the surface of the device housing 1, and an adjusting plate 3 slidably installed inside the fixed column 2 via a slider. Two sets of adjusting plates 3 are symmetrically installed inside the fixed column 2. A second threaded rod 18 is rotatably installed inside the fixed column 2 via a bearing. The second threaded rod 18 passes through the slider of the adjusting plate 3 and is threadedly connected to it. The second threaded rod 18 is simultaneously threaded to both sets of adjusting plates 3. Two sets of threads in opposite directions are provided on the surface of the second threaded rod 18. When the second threaded rod 18 rotates, it drives the two sets of threaded adjusting plates 3 to move towards each other. A cutting blade 8 is disposed on the surface of the adjusting plate 3. When the adjusting plate 3 moves, it drives the cutting blade 8 to move. Rotating the second threaded rod 18 causes the two sets of adjusting plates 3 to move towards each other, which in turn causes the adjusting plates 3 to move the cutting blade 8, thereby changing the distance between the two sets of cutting blades 8 and achieving adjustment of different cutting widths. This improves the adaptability of the device to different cutting widths. The second auxiliary wheel 9 is rotatably mounted on the surface of the adjusting plate 3 via a rotating shaft. The second auxiliary wheel 9 is located on one side of the cutting blade 8. When the adjusting plate 3 moves, it will drive the rotatably connected second auxiliary wheel 9 to move. The first mounting block 5 is slidably mounted inside the adjusting plate 3. When the adjusting plate 3 moves, it will drive the slidably connected first mounting block 5 to move. The surface of the first mounting block 5 is rotatably mounted on the first auxiliary wheel 7 via a rotating shaft. The first auxiliary wheel 7 is located on one side of the top of the second auxiliary wheel 9. When the first mounting block 5 moves, it will drive the second auxiliary wheel 9 to move. The first auxiliary wheel 7 moves, and the flexible printing base film passing between the first auxiliary wheel 7 and the second auxiliary wheel 9 can be clamped and limited, thereby facilitating the cutting blade 8 to cut the flexible printing base film. A first spring 6 is fixed to the top of the first mounting block 5. One end of the first spring 6 is fixed to the surface of the first mounting block 5, and the other end is fixed to the surface of the adjusting plate 3. When the first mounting block 5 moves, it will squeeze the first spring 6, causing the first spring 6 to deform. When there is no external force interference, the first spring 6 will push the first mounting block 5 to move. A limit rod is fixed to the top of the first mounting block 5. The first spring 6 is sleeved on the surface of the limit rod. The top end of the limit rod passes through the surface of the adjusting plate 3 and is slidably connected to it. The limit rod can control the first mounting block 5. The position of the first mounting block 5 is restricted to prevent it from tilting or wobbling during movement, thus improving its stability. A drive motor 4 is fixed to the surface of the adjusting plate 3; when the adjusting plate 3 moves, it drives the fixed drive motor 4 to move. A winding roller 10 is fixed to the top of the output shaft of the drive motor 4; the drive motor 4 can drive the winding roller 10 fixed to the top of the output shaft to rotate. A limiting ring 14 is sleeved on the surface of the winding roller 10, with a portion of the limiting ring 14 located inside the winding roller 10 and slidably connected to it. When the winding roller 10 rotates, it drives the sleeved limiting ring 14 to rotate. A connecting ring 12 is rotatably mounted on the surface of the limiting ring 14 via a bearing. A first threaded rod 13 is rotatably mounted inside the winding roller 10 via a bearing.The first threaded rod 13 passes through the interior of the limiting ring 14 and is threadedly connected to the limiting ring 14. When the first threaded rod 13 rotates, it will drive the threadedly connected limiting ring 14 to move. The limiting plate 17 is fixed to the surface of the connecting ring 12. The limiting plate 17 has a limiting groove inside. The second mounting block 16 is slidably mounted inside the adjusting plate 3. The second spring 11 is fixed to the top of the second mounting block 16. One end of the second spring 11 is fixed to the surface of the second mounting block 16, and the other end is fixed to the inner surface of the adjusting plate 3. When the second mounting block 16 moves, it will compress the second spring 11, causing the second spring 11 to deform. When there is no external force interference, the second spring 11 will push the second mounting block 16 to move. The multi-segment telescopic rod 15 is fixed to the surface of the second mounting block 16. The multi-segment telescopic rod 15 moves... When the device moves, it will cause the fixed second mounting block 16 to move. One end of the multi-segment telescopic rod 15 is fixed to the surface of the second mounting block 16, and the other end is slidably mounted inside the limiting groove of the limiting plate 17 via a slider. The surface of the slider is provided with a limiting block, which can restrict the position of the other end of the multi-segment telescopic rod 15, preventing the other end of the multi-segment telescopic rod 15 from detaching from the inside of the limiting plate 17. The second spring 11 and the second mounting block 16 can push the multi-segment telescopic rod 15 so that the surface of the multi-segment telescopic rod 15 contacts the surface of the winding roller 10, thereby allowing the multi-segment telescopic rod 15 to squeeze the surface of the waste roll collected on the surface of the winding roller 10, improving the quality of the waste roll during winding, and preventing the waste that has been wound on the surface of the winding roller 10 from being thrown out when the waste breaks.
[0023] Working principle: When it is necessary to trim the flexible printing base film, the base film is moved between the first auxiliary wheel 7 and the second auxiliary wheel 9 and towards one side of the cutting blade 8. The cutting blade 8 then trims the flexible printing base film. The trimmed waste material is wound onto the surface of the winding roller 10. At the same time, the position of the limiting ring 14 can be adjusted by rotating the first threaded rod 13, thereby changing the winding collection width on the surface of the winding roller 10. This avoids the problem that relatively thin waste material will deviate when wound onto the surface of the winding roller 10 due to the inability to adjust the winding collection width of the winding roller 10, resulting in the waste material not being able to be wound into a complete roll, which is inconvenient for personnel to process the waste roll later. It is relatively convenient to use.
[0024] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
