Technical Field

[0001] This utility model relates to the field of printing equipment technology, and in particular to a printing press tension control device. Background Technology

[0002] A printing press is a machine for printing text and images. Modern printing presses generally consist of mechanisms for plate mounting, inking, printing, and paper feeding (including folding). During printing, in order to improve the quality of the printed products, the tension of the printed products needs to be adjusted.

[0003] In the existing printing process, tension cannot be directly adjusted manually or in real time, making it inconvenient to use and affecting the printing quality of the product. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a printing press tension control device to solve the aforementioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The printing press tension control device includes:

[0007] The base has two side plates fixedly installed on its top side, and the side plates have two deflection holes and a rotating groove;

[0008] Two tensioning components are respectively set in the deflection ports of the two side plates. The two tensioning components can deflect within the deflection ports of the two side plates to adjust the tension of the paper wrapped around the two tensioning components.

[0009] Two side gear assemblies are respectively disposed on one side of the corresponding side plate, and the side gear assemblies are used to adjust the deflection of the two tensioning assemblies;

[0010] Two transmission components are respectively disposed on one side of the corresponding side plate, and the transmission components are used to adjust the rotation of the side gear assembly;

[0011] The elastic translation component is disposed in the base and is configured to adjust its elastic position when subjected to the rotational force of the two transmission components.

[0012] Preferably, the two deflection openings on the side plate are symmetrically arranged, and the deflection openings are arranged in a fan-shaped structure.

[0013] Preferably, the tensioning assembly includes:

[0014] The mounting rod has its two ends extending through corresponding deflection holes on the two side plates;

[0015] The tensioning wheel is fixedly mounted on the mounting rod and is located between the two side plates.

[0016] Two first gears are fixedly mounted on the mounting rod and extend to one end of the corresponding deflection opening on the two side plates.

[0017] Preferably, the side gear assembly includes:

[0018] An internal gear ring is rotatably mounted in a slot on one side of a side plate, and the internal gear ring meshes with a first gear at one end of two mounting rods;

[0019] The first external toothed ring is fixedly installed on the outside of the internal toothed ring;

[0020] The second external gear ring is fixedly installed on one side of the side plate, and the second external gear ring meshes with the first gear at one end of the two mounting rods.

[0021] Preferably, the transmission assembly includes:

[0022] A rotating shaft is mounted on one side of the side plate.

[0023] The second gear is fixedly mounted on the rotating shaft and meshes with the first external gear ring.

[0024] Preferably, the top side of the base has two sliding grooves, the cross section of the sliding grooves is arranged in a cross shape, the base has a mounting cavity, and the mounting cavity is connected to the two sliding grooves.

[0025] Preferably, the elastic translation component includes:

[0026] Two racks are movably installed in corresponding slide grooves, the racks and slide grooves are adapted to the cross-shaped structure of the racks, and the racks mesh with corresponding second gears;

[0027] The mounting plate is movably installed in the mounting cavity, and the mounting plate is fixedly installed between the two racks;

[0028] Two springs, one end of which is fixedly installed on both sides of the mounting plate, and the other end of which is fixedly installed on the inner walls of both sides of the mounting cavity.

[0029] When the printing press is printing on paper, if the paper tension is too high, the two ends of the mounting rods on the two tensioning wheels rotate counterclockwise in corresponding deflection holes on the two side plates, thereby reducing the paper tension. At this time, under the meshing transmission of the two sets of side gear assemblies and transmission assemblies, the two racks are synchronously driven to slide to the left in their corresponding slide grooves, which in turn causes the mounting plate to slide to the left in the mounting cavity. This exerts a force on the spring on the left side of the mounting plate, causing it to deform and compress, while the spring on the right side of the mounting plate deforms and stretches, thus reducing the paper tension of the printing press. The automatic tension adjustment system ensures that the paper is transported under appropriate tension when the tension is too high. Simultaneously, when the paper tension is excessive, the two ends of the mounting rods on the two tension rollers rotate clockwise within corresponding deflection openings on the two side plates. This indirectly moves the mounting plate to the right, causing the spring on the right side of the mounting plate to deform and compress, while the spring on the left side deforms and stretches. This automatic tension adjustment system addresses situations where the paper tension is too low, maintaining an appropriate tension and ensuring the printing quality of the paper.

[0039] like Figure 4As shown, two side gear assemblies 300 are installed. Each of the two side plates 101 has a rotating groove 1012 on one side. The two side gear assemblies 300 are respectively disposed on one side of the corresponding side plate 101. The side gear assemblies 300 are used to adjust the deflection of the two tensioning components 200. The side gear assembly 300 includes: an internal gear ring 301, a first external gear ring 302, and a second external gear ring 303. The internal gear ring 301 is rotatably installed in the rotating groove 1012 on one side of the side plate 101 and meshes with the first gear 203 at one end of the two mounting rods 201. The first external gear ring 302 is fixedly installed on the outside of the internal gear ring 301. The second external gear ring 303 is fixedly installed on one side of the side plate 101 and meshes with the first gear 203 at one end of the two mounting rods 201.

[0040] Continue as Figure 4 As shown, two transmission components 400 are respectively disposed on one side of the corresponding side plate 101. The transmission components 400 are used to adjust the rotation of the side gear assembly 300. The transmission component 400 includes: a rotating shaft 401 and a second gear 402. The rotating shaft 401 is rotatably mounted on one side of the side plate 101. The second gear 402 is fixedly mounted on the rotating shaft 401 and meshes with the first external gear ring 302.

[0041] Continue as Figure 4 As shown, the elastic translation component 500 is configured to adjust its elastic position when subjected to the rotational force of the two transmission components 400.

At this time, under the meshing transmission action of the two sets of side gear assemblies 300 and transmission assembly 400, the two racks 501 are synchronously driven to slide to the left in the corresponding slide grooves 1001, thereby causing the mounting plate 502 to slide to the left in the mounting cavity 1002. This exerts a force on the spring 503 on the left side of the mounting plate 502, causing it to deform and compress, while the spring 503 on the right side of the mounting plate 502 deforms and stretches, thus achieving... The automatic tension adjustment system addresses the issue of excessive paper tension in the printing press, ensuring the paper is transported under appropriate tension. Simultaneously, when the paper tension is too high, the two ends of the mounting rods 201 on the two tensioning rollers 202 rotate clockwise within corresponding deflection ports 1011 on the two side plates 101. This indirectly moves the mounting plate 502 to the right, causing the spring 503 on the right side of the mounting plate 502 to deform and compress, while the spring 503 on the left side of the mounting plate 502 deforms and stretches. This automatic tension adjustment system addresses the issue of insufficient paper tension in the printing press, maintaining the paper under appropriate tension and ensuring the printing quality.
