[0002] A printing press is a machine for printing text and images. Modern printing presses are generally composed of mechanisms such as plate loading, inking, embossing, and paper feeding (including folding). Its working principle is: first, the text and image to be printed are made into a printing plate, which is then installed on the printing press. Then, ink is applied to the places on the printing plate where the text and image are, either manually or by the printing press, and then directly or indirectly transferred to paper or other substrates, thereby replicating a printed product identical to the printing plate.

After the leveling is completed, the bottom of the adjusting screw is rotatably connected to the bracket, and the inside of the bracket is fixedly connected to a pressure block, thereby fixing the material above the working plate.

[0004] In the prior art, the leveling method adopted is leveling by roller skating, which has the advantages of fast leveling and convenient operation. However, when the leveling height is fine-tuned, due to the limitation of the structural installation method, the adjustment time is prolonged, and the leveling wheels need to be pressed down one by one, resulting in different adjustment heights, and the cardboard cannot be leveled on a horizontal plane, resulting in poor leveling effect. In addition, due to the different contact strengths of the leveling wheels with the cardboard, some parts are severely worn; secondly, due to the complex installation structure of the bracket of the leveling wheel, the fixing method cannot be quickly disassembled, resulting in a long time for repair and maintenance operations, which is not conducive to convenient maintenance of the leveling mechanism. Therefore, it is necessary to provide a printing production die-cutting leveling device. Utility Model Content

[0006] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a printing production die-cutting and leveling device, including a printing platform, a support plate, a leveling mechanism, and a baffle. A support plate is arranged in the middle of the printing platform, a leveling mechanism is arranged at the bottom of the support plate, and baffles are arranged on the printing platform on both sides of the leveling mechanism. The leveling mechanism includes a positioning screw, an adjusting screw, a bearing, and a rotating nut.

The bottom of the fixing frame 1 is symmetrically provided with leveling wheels.

[0007] Preferably, the positioning screw is located on the upper part of the support plate and is threadedly mounted with a nut 1.

[0008] Preferably, a second nut is provided on the top of the rotating nut and the positioning screw is located thereon. The second nut is installed in abutment with the top of the rotating nut.

[0009] Preferably, the rotating nut includes a cylindrical barrel portion 1, a truncated cone barrel portion, and a cylindrical barrel portion 2. The interior of the cylindrical barrel portion 1 is clamped and installed with a bearing, and the bottom of the cylindrical barrel portion 1 is sequentially arranged as a truncated cone barrel portion and a cylindrical barrel portion 2.

[0010] Preferably, the interior of the second cylindrical barrel portion is provided with a threaded structure, and the threaded structure is threadedly connected to the adjusting screw.

[0011] Preferably, at least one fixing frame 2 is evenly arranged between the fixing frames 1, leveling wheels are symmetrically arranged at the bottom of the fixing frames 2, and the fixing frames 2 are connected by a fixing plate 1.

[0012] In summary, the utility model provides a printing production die-cutting and leveling device, which can be quickly installed and disassembled, specifically: the positioning screw is threadedly installed with the threaded hole on the support plate, and the positioning screw is fixed to the support plate by nut one, the bottom of the positioning screw is rotatably installed with a rotating nut through a bearing, and the internal thread of the rotating nut is connected to the adjusting screw, so that the up and down fine-tuning of the adjusting screw can be achieved through the self-rotation of the rotating nut, and the leveling wheel can be quickly fine-tuned. After the fine-tuning is completed, the top of the rotating nut is fastened and installed by nut two, so that the rotating nut is limitedly installed on the positioning screw; when disassembling and maintaining, the rotating nut is removed by loosening nut one and nut two, and the adjusting screw is removed from the rotating nut by thread disassembly, so as to maintain and replace the leveling wheel; it solves the problem of existing fixed structure installation method, which is not conducive to rapid disassembly and maintenance, and reduces the time efficiency of maintenance.

[0013] The adjusting screw can be fine-tuned up and down by means of the threaded connection between the adjusting screw and the rotating nut. Due to the hollow setting of the rotating nut and the accommodating hole structure at the bottom of the positioning screw, there is space for fine-tuning the adjusting screw up and down, so as to achieve the up and down adjustment of the adjusting screw and the up and down fine-tuning of the leveling wheel, so as to adapt to the leveling of cardboards of different thicknesses. This solves the problem in the prior art that the fine-tuning method takes a long time due to its complex structure and the inability to achieve the linkage adjustment method, and the leveling wheel has different heights, resulting in different leveling forces and poor leveling efficiency. In this patent, the adjusting screws on both sides are fine-tuned to achieve fine-tuning of the overall leveling wheel height, and linkage adjustment is achieved, thereby reducing the timeliness of the leveling wheel fine-tuning and improving the leveling wheel fine-tuning to be on the same horizontal plane, so as to achieve the flatness of the leveling.

[0026] In the prior art, the leveling method adopted is leveling by roller skating, which has the advantages of fast leveling and convenient operation. However, when fine-tuning the leveling height, due to the limitation of the structural installation method, the adjustment time is prolonged, and the leveling wheels need to be pressed down one by one, resulting in different adjustment heights, and it is impossible to level the cardboard on a horizontal plane, resulting in poor leveling effect. In addition, due to the different contact strengths of the leveling wheels with the cardboard, some parts are severely worn. Secondly, due to the complex installation structure of the bracket of the leveling wheel, the fixing method cannot be quickly disassembled, resulting in a long time for repair and maintenance operations, which is not conducive to convenient maintenance of the leveling mechanism.

[0027] Through the structure of the present patent, it can be achieved that: threaded holes 13 are symmetrically arranged in the length direction of the support plate 2, the threaded holes 13 are threadedly connected to the positioning screw 5, the bottom of the positioning screw 5 is clamped and installed with a bearing 7, the outer clamping installation of the bearing 7 is clamped and installed with a rotating nut 11, the bottom of the rotating nut 11 is internally threadedly installed with an adjusting screw 6, and the bottom of the adjusting screw 6 is installed with a leveling wheel 16 through a fixing frame 15.
