Description

Technical Field

[0001] The utility model relates to the technical field of printing machines, and more specifically, to a beam support device for a printing machine. Background Art

[0002] A printing press is a machine that prints text and images. It is the preferred equipment for various printed materials. Its application fields are very wide, including books, packaging, commercial printing, product label printing, etc. Modern printing presses are generally composed of mechanisms such as plate mounting, inking, embossing, and paper feeding (including folding). By making these mechanisms work together, printing tasks can be completed efficiently and accurately.

[0003] The existing printing press joist device does have some obvious shortcomings in practical applications. Due to the particularity of the printing industry, the stencils used are of various types and sizes, which puts forward higher adaptability and adjustability requirements for the joist device. However, many printing press joist devices on the market are relatively fixed in design. Once installed on the printing press, its position and size are difficult to adjust flexibly. This limitation brings a lot of trouble in use. Whenever it is necessary to adapt to stencils of different sizes, operators often need to manually replace the corresponding joists according to the size of the stencil. This not only increases the complexity and workload of the operation, but also greatly reduces the printing efficiency. In addition, the need to replace the joist may also lead to extended downtime during the printing process, further affecting the overall production progress. More importantly, the existing joist device lacks adjustment function, which greatly reduces its practicality in practical applications. Faced with stencils of different sizes and types, operators often find it difficult to find a fully matched joist, which may cause the stencil to be unable to be placed stably during the printing process, thereby affecting the quality of the printed product. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a printing press support beam device, which has the advantage of high practicability.

[0028] Inner groove 7, the inner groove 7 is vertically opened inside the rectangular groove 2, a clamping block 8 is movably installed inside the inner groove 7, a sleeve block 6 is fixedly installed between two clamping blocks 8, and the sleeve block 6 is movably installed on the surface of the bidirectional screw rod 3, and the number of the sleeve blocks 6 is two groups;

[0029] A joist 10, which is fixedly installed between two socket blocks 6;

[0030] When in use, the mesh plate is fixed on the top of the support beam 10, and then the staff rotates the handle 5, and the rotation of the handle 5 drives the bidirectional screw 3 inside the rectangular groove 2 to rotate, so that the two sets of sleeve blocks 6 on the surface of the bidirectional screw 3 move relatively, and at the same time as the sleeve blocks 6 move, the top and bottom blocks 8 thereof slide synchronously inside the inner groove 7;

[0031] Turning the handle 5 causes the bidirectional screw 3 to rotate, and the two sets of sleeve blocks 6 move relative to each other. At the same time, the blocks 8 at the top and bottom of the sleeve blocks 6 slide inside the inner groove 7. Compared with the traditional device, this device can be accurately adjusted according to the size of the printing material, thereby greatly improving the versatility and flexibility of the printing press, and at the same time helping to ensure that the printing material remains stable during the printing process, reducing printing errors caused by material shaking or displacement, thereby helping to improve the quality of printed products and achieve more refined printing effects.

[0032] The top of the joist 10 is provided with a slide groove 14, the interior of the joist 10 is provided with a cavity 11 extending to the bottom of the joist 10, and a fixing plate 12 is fixedly installed in the middle of the cavity 11;

[0034] A spring 17, wherein the spring 17 is disposed between the movable plate 15 and the fixed plate 12;

[0035] After the mesh plate is placed on the surface of the joist 10, the staff starts the electric push rod 13, and the thrust of the electric push rod 13 pushes the movable plate 15 to move toward the fixed plate 12 and squeezes the spring 17 at the same time. At this time, the clamping block 16 on the top of the movable plate 15 also moves synchronously with the movement of the movable plate 15, thereby limiting and fixing the mesh plate on the surface of the joist 10;

[0036] The thrust of the electric push rod 13 pushes the movable plate 15 so that the clamping block 16 also moves synchronously to clamp the screen. At the same time, the thrust of the slide groove 14 makes the spring 17 compressed. Compared with the traditional device, this device can ensure that the screen remains stable during the printing process and reduce printing errors caused by vibration or displacement, which helps to achieve more precise and accurate printing effects and improve the quality of printed products. In addition, through the distance between the two clamping blocks 16, it can easily adapt to screens of different sizes, thereby improving the flexibility and adaptability of the printer.

[0037] There are two handles 5, and the surfaces of the two handles 5 are both provided with a sponge layer;

[0038] There are two handles 5 , and sponge layers are provided on the surfaces of the two handles 5 . The use of the sponge layers makes it more comfortable for the staff to turn the handles 5 , thereby improving the happiness of the staff at work.

[0042] The clamping block 16 has a C-shaped shape, and a rubber layer is provided on the inner surface of the clamping block 16. The rubber layer provided inside the clamping block 16 prevents the surface of the screen from being damaged when limiting the position, thereby ensuring the quality and accuracy of printing.

[0043] The two main beams 1 are both made of stainless steel and are movably mounted inside the printing press by bolts;

[0044] The two main beams 1 are both made of stainless steel and are movably installed inside the printing press by bolts. The high strength of stainless steel allows the main beams 1 to extend their service life. The main beams 1 can be disassembled by bolts, making it easier to clean them.

[0045] The working principle and use process of this utility model:

[0046] When in use, the mesh plate is fixed on the top of the supporting beam 10, and then the staff turns the handle 5. The rotation of the handle 5 drives the bidirectional screw 3 inside the rectangular groove 2 to rotate, and the two groups of socket blocks 6 on the surface of the bidirectional screw 3 move relative to each other. At the same time, when the socket blocks 6 move, the top and bottom blocks 8 thereof slide synchronously inside the inner groove 7.
