Description

Technical Field

[0001] This utility model belongs to the technical field of plate-forming machine loading table, and particularly relates to an extension mechanism for plate-forming machine loading table. Background Technology

[0002] A plate setter is a printing plate-making device that automatically completes the entire process of CTP plate development, fixing, washing, and drying, quickly restoring images and text, improving plate-making efficiency, and is widely used in newspapers and printing plants. It 100% replaces manual plate setting and ensures printing quality.

[0003] Most plate-making machine loading tables have several drawbacks in use. For example, if the loading table lacks an extension mechanism, it cannot accommodate plates of various sizes. Large plates suspended in the air cause instability, requiring frequent lifting by workers, which reduces work efficiency. Furthermore, there is too much idle space for small plates, which easily accumulates dust and wastes space. Therefore, we propose an extension mechanism for plate-making machine loading tables. Utility Model Content

[0004] The purpose of this invention is to provide an extension mechanism for the loading table of a plate-making machine to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides an extension mechanism for a plate-forming machine's loading table, including a plate-forming machine, a fixed plate, an extension plate, and two hinges, and further includes:

[0006] A sliding plate is slidably installed at the bottom of a fixed plate. An extension plate is disposed on one side of the fixed plate. Two hinges are fixedly installed between the fixed plate and the extension plate. One side of the sliding plate extends into the extension plate and is inserted into the extension plate. The fixed plate is fixedly installed at the feeding port of the plate punching machine.

[0007] Four sliding grooves are respectively opened on both sides of the fixed plate and the extension plate. A sliding block is slidably installed in each of the four sliding grooves. A rectangular column is provided on both sides of the fixed plate, and two of the rectangular columns are fixedly connected to the four sliding blocks respectively.

[0008] A plurality of limiting components, all of which are located within the sliding plate and are used to limit the position of the sliding plate;

[0009] Two sets of fixing components are located inside two rectangular columns, and are used to fix the positions of the two rectangular columns respectively.

[0010] In this technical solution, when the length of the fixed plate is insufficient and needs to be extended, the rectangular column can be pulled away from the plate punching machine by the fixed component. When both rectangular columns are pulled to the appropriate position, the extension plate is rotated. When the extension plate and the fixed plate are on the same horizontal plane, the fixed plate and the two sides of the extension plate can be fixed by the fixed component.

[0011] The sliding plate moves towards the extension plate. The position of the sliding plate can be fixed by the set limiting components. The sliding plate can connect the bottom of the fixed plate and the extension plate to ensure that the fixed plate and the extension plate are tightly and stably connected during use.

[0012] In the above technical solution, the limiting component further includes:

[0013] The groove is formed inside the sliding plate. A first limiting post is slidably installed inside the groove. A first spring is fixedly installed at the bottom end of the first limiting post and fixed to the inner wall of the groove. The top end of the first limiting post penetrates the groove and extends into the fixed plate and the extension plate. The first limiting post is inserted into the fixed plate and the extension plate.

[0014] In this technical solution, the operator pulls the sliding plate towards the extension plate, causing the fixed plate to press several first limiting posts downwards. At the same time, several first springs are compressed and contracted. When the sliding plate reaches the appropriate position, under the rebound force of the first springs, the first limiting posts slide upwards and insert into the extension plate, thus fixing the position of the sliding plate. The sliding plate can connect the bottom of the fixed plate and the extension plate, ensuring a tight and stable connection between the fixed plate and the extension plate during use.

[0015] In the above technical solution, the fixing component further includes:

[0016] A limiting groove is formed inside a rectangular column. A sliding strip is slidably installed inside the limiting groove. Two sliding columns are fixedly installed on one side of the sliding strip, and several second springs fixed to the inner wall of the limiting groove are fixedly installed on one side of the sliding strip.

[0017] Two second limiting posts are fixedly installed on the other side of the sliding strip. One end of each second limiting post passes through two sliding blocks and extends into the fixed plate and the extension plate, respectively. One end of each second limiting post is inserted into the fixed plate and the extension plate, respectively. Both sliding posts and the two second limiting posts are slidably connected to the limiting groove. One end of each second limiting post is slidably connected to the two sliding blocks.

[0018] In this technical solution, when the length of the fixed plate is insufficient and needs to be extended, one of the sliding columns is first pulled to slide. One of the sliding columns drives the sliding strip, another sliding column, and two second limiting columns to slide. At the same time, several second springs are compressed and contracted. After the two second limiting columns are disengaged from the fixed plate and the extension plate, the rectangular column is pulled away from the plate punching machine. When both rectangular columns are pulled to the appropriate position, the extension plate is rotated. When the extension plate and the fixed plate are on the same horizontal plane, under the action of the rebound force of several second springs, the rotating plate, the two sliding columns, the sliding strip, and the two second limiting columns slide. Finally, the two second limiting columns are inserted into the fixed plate and the extension plate respectively, which can fix the two sides of the fixed plate and the extension plate.

[0019] In the above technical solution, one end of one of the sliding columns is rotatably mounted with a handle.

[0020] In this technical solution, a handle is provided to facilitate pulling one of the sliding columns.

[0021] In the above technical solution, furthermore, the tops of several of the first limiting posts are all arc-shaped.

[0022] In this technical solution, it is ensured that the fixing plate will squeeze several first limiting posts to slide downwards.

[0023] In the above technical solution, further, a plurality of the first limiting posts are distributed at equal intervals on the sliding plate.

[0024] In this technical solution, several first limiting posts are ensured to fix the position of the sliding plate.

[0025] In the above technical solution, a rotating plate is further fixedly installed at the bottom of the sliding plate.

[0026] In this technical solution, when the rotating plate is stuck on the rectangular column, the positions of the two second limiting columns can be fixed.

[0027] The beneficial effects of this utility model are:

[0028] 1. The plate-making machine's loading platform uses an extension mechanism. When the length of the fixed plate is insufficient and needs to be extended, the rectangular column can be pulled away from the plate-making machine through the set fixing components. When both rectangular columns are pulled to the appropriate position, the extension plate is rotated. When the extension plate and the fixed plate are on the same horizontal plane, the fixed plate and the two sides of the extension plate can be fixed through the set fixing components, which extends the length of the loading area. The operation is convenient and does not require tools, thus expanding the application range of the overall device.

[0029] 2. The plate-making machine's loading platform uses an extension mechanism. The operator slides the sliding plate towards the extension plate. Through the set limiting components, the position of the sliding plate can be fixed. The sliding plate can connect the bottom of the fixed plate and the extension plate, ensuring that the fixed plate and the extension plate are tightly and stably connected during use, thus ensuring the stability of the entire device during use.

[0046] Example 1:

[0047] Please see Figure 1 - Figure 9 As shown, this embodiment provides an extension mechanism for the loading table of a plate-forming machine, including a plate-forming machine 1, a fixed plate 2, an extension plate 3, and two hinges 4, and also includes:

[0048] The sliding plate 5 is slidably installed at the bottom of the fixed plate 2. The extension plate 3 is set on one side of the fixed plate 2. Both hinges 4 are fixedly installed between the fixed plate 2 and the extension plate 3. One side of the sliding plate 5 extends into the extension plate 3, and one side of the sliding plate 5 is inserted into the extension plate 3. The fixed plate 2 is fixedly installed at the feeding port of the plate punching machine 1.

[0049] Four sliding grooves 6 are respectively opened on both sides of the fixed plate 2 and the extension plate 3. Sliding blocks 7 are slidably installed in each of the four sliding grooves 6. Rectangular columns 8 are provided on both sides of the fixed plate 2. Two rectangular columns 8 are fixedly connected to the four sliding blocks 7 respectively.

[0050] Several limiting components are located within the sliding plate 5 and are used to limit the position of the sliding plate 5.

[0051] Two sets of fixing components are located inside the two rectangular columns 8, and are used to fix the positions of the two rectangular columns 8 respectively.

[0052] When the length of the fixed plate 2 is insufficient and needs to be extended, the rectangular column 8 can be pulled away from the plate punching machine 1 by the fixed components. When both rectangular columns 8 are pulled to the appropriate position, the extension plate 3 is rotated. When the extension plate 3 and the fixed plate 2 are on the same horizontal plane, the fixed plate 2 and the two sides of the extension plate 3 can be fixed by the fixed components.

[0053] The sliding plate 5 slides towards the extension plate 3. The position of the sliding plate 5 can be fixed by the set limiting components. The sliding plate 5 can connect the bottom of the fixed plate 2 and the extension plate 3 to ensure that the fixed plate 2 and the extension plate 3 are tightly and stably connected during use.

[0054] In this embodiment, the limiting component includes:

[0055] The groove 9 is formed in the sliding plate 5. A first limiting post 10 is slidably installed in the groove 9. A first spring 11 fixed to the inner wall of the groove 9 is fixedly installed at the bottom end of the first limiting post 10. The top end of the first limiting post 10 passes through the groove 9 and extends into the fixed plate 2 and the extension plate 3. The first limiting post 10 is inserted into the fixed plate 2 and the extension plate 3.

[0056] When the worker pulls the sliding plate 5 towards the extension plate 3, the fixing plate 2 will press several first limiting posts 10 to slide downwards, and at the same time several first springs 11 will be compressed and contracted. When the sliding plate 5 slides to the appropriate position, under the action of the rebound force of several first springs 11, several first limiting posts 10 will slide upwards and insert into the extension plate 3, which can fix the position of the sliding plate 5. The sliding plate 5 can connect the bottom of the fixing plate 2 and the extension plate 3, ensuring that the fixing plate 2 and the extension plate 3 are tightly and stably connected during use.

[0057] In this embodiment, the fixing component includes:

[0058] The limiting groove 12 is opened in the rectangular column 8. A sliding strip 14 is slidably installed in the limiting groove 12. Two sliding columns 15 are fixedly installed on one side of the sliding strip 14, and several second springs 16 fixed to the inner wall of the limiting groove 12 are fixedly installed on one side of the sliding strip 14.

[0059] Two second limiting posts 17 are fixedly installed on the other side of the sliding strip 14. One end of each second limiting post 17 passes through the two sliding blocks 7 and extends into the fixed plate 2 and the extension plate 3 respectively. One end of each second limiting post 17 is inserted into the fixed plate 2 and the extension plate 3 respectively. The two sliding posts 15 and the two second limiting posts 17 are slidably connected to the limiting groove 12. One end of each second limiting post 17 is slidably connected to the two sliding blocks 7 respectively.

[0060] When the length of the fixed plate 2 is insufficient and needs to be extended, one of the sliding columns 15 is first pulled to slide. One of the sliding columns 15 drives the sliding strip 14, the other sliding column 15, and the two second limiting columns 17 to slide. At the same time, several second springs 16 are compressed and contracted. After the two second limiting columns 17 are separated from the fixed plate 2 and the extension plate 3 respectively, the rectangular column 8 is pulled away from the plate punching machine 1. When both rectangular columns 8 are pulled to the appropriate position, the extension plate 3 is rotated. When the extension plate 3 and the fixed plate 2 are on the same horizontal plane, under the action of the rebound force of several second springs 16, the rotating plate 18, the two sliding columns 15, the sliding strip 14, and the two second limiting columns 17 slide. Finally, the two second limiting columns 17 are inserted into the fixed plate 2 and the extension plate 3 respectively, which can fix the two sides of the fixed plate 2 and the extension plate 3.

[0064] The handle 13 allows for easy pulling of one of the sliding columns 15.

[0065] Example 3:

[0066] This embodiment provides an extension mechanism for the loading table of a plate-making machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0067] In this embodiment, the tops of several first limiting posts 10 are all arc-shaped.

[0068] In this process, the fixing plate 2 is ensured to compress several first limiting posts 10 and slide downwards.

[0069] Example 4:

[0070] This embodiment provides an extension mechanism for the loading table of a plate-making machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0071] In this embodiment, a plurality of first limiting posts 10 are distributed at equal intervals on the sliding plate 5.

[0072] Specifically, this ensures that several first limiting posts 10 can fix the position of the sliding plate 5.

[0073] Example 5:

[0074] This embodiment provides an extension mechanism for the loading table of a plate-making machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0075] In this embodiment, a rotating plate 18 is fixedly installed at the bottom of the sliding plate 5.

[0076] When the rotating plate 18 is locked onto the rectangular column 8, the positions of the two second limiting columns 17 can be fixed.

[0077] The structure and principle of the plate-making machine 1 in this embodiment are existing technologies. For details, please refer to the prior art document (publication number CN209543047U, patent name: Plate-making machine with extendable feeding table), which will not be repeated here.

[0078] Working principle: When the length of the fixed plate 2 is insufficient and needs to be extended, the rotating plate 18 is first pulled to slide away from the fixed plate 2. The rotating plate 18 drives one of the sliding pillars 15 to slide, and the sliding pillar 15 drives the sliding strip 14, the other sliding pillar 15, and the two second limiting pillars 17 to slide. At the same time, several second springs 16 are compressed and contracted. After the two second limiting pillars 17 are disengaged from the fixed plate 2 and the extension plate 3 respectively, the rotating plate 18 is rotated in the forward direction. Under the action of the rebound force of several second springs 16, the rotating plate 18 will be stuck on the rectangular pillar 8, which can adjust the length of the fixed plate 18. The positions of the two second limiting posts 17 are fixed. Then, the rectangular post 8 is pulled away from the plate punching machine 1. When both rectangular posts 8 are pulled to the appropriate position, the extension plate 3 is rotated. When the extension plate 3 and the fixed plate 2 are on the same horizontal plane, the rotating plate 18 is rotated in the opposite direction and then released. Under the action of the rebound force of several second springs 16, the rotating plate 18, the two sliding posts 15, the sliding strip 14 and the two second limiting posts 17 slide. Finally, the two second limiting posts 17 are inserted into the fixed plate 2 and the extension plate 3 respectively, which can fix the two sides of the fixed plate 2 and the extension plate 3.

[0079] The operator pulls handle 13 and moves sliding plate 5 towards extension plate 3. Fixing plate 2 will press several first limiting posts 10 downward, while several first springs 11 are compressed and contracted. When sliding plate 5 slides to the appropriate position, under the rebound force of several first springs 11, several first limiting posts 10 slide upward and insert into extension plate 3, which can fix the position of sliding plate 5. Sliding plate 5 can connect the bottom of fixing plate 2 and extension plate 3 to ensure that fixing plate 2 and extension plate 3 are tightly and stably connected during use.

[0080] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
