AI Technical Summary
During the winding process of traditional pressing rollers, due to insufficient spring pressure, the pressure on the winding material of the pressing roller is relatively loose, resulting in problems such as loose inner and tight outer, deformation of film rolls, difficulty in unwinding, slip rolling and stacking.
The combined structure of the hydraulic cylinder and the intermediate plate is adopted, and the height of the intermediate plate is adjusted by lifting and lowering of the hydraulic cylinder, thereby adjusting the pressure of the pressure roller to the coiled material.
The pressure adjustable of the pressure roller during the winding process is achieved, which avoids adverse phenomena caused by insufficient pressure in traditional technology, and ensures the stability and quality of the winding.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of winding mechanisms, in particular to a pressure-adjustable pressure roller winding mechanism. Background Art
[0002] In the printing and winding process, the pressure roller is extremely important to the winding mechanism. As a key component of the winding system, the pressure roller's main function is to ensure that the printed material can fit flat and tightly on the roll when winding, avoiding undesirable phenomena such as wrinkles, looseness or overlap. By applying appropriate pressure, the pressure roller can effectively control the tension of the material and maintain a stable winding state, which is crucial to ensuring the final quality and appearance of the printed product.
[0003] In the process of implementing the solution, the inventors found that the following problems existed in the prior art and have not been well solved: when the traditional pressure roller is winding, the pressure roller is simply extended and retracted by the elastic pressure of the spring. When the thickness of the winding increases, the winding material squeezes the pressure roller, and the pressure roller presses the spring. The spring contracts under pressure, so that the roller presses down on the winding material during the winding process. In order to avoid unnecessary damage to the winding material caused by the pressure of the spring on the pressure roller, a spring with a smaller elastic coefficient is generally provided. However, this will cause the pressure of the pressure roller on the winding material to be loose, resulting in problems such as loose inside and tight outside, deformation of the film roll, difficulty in unwinding, slippage and stacking. Therefore, the present application proposes a pressure-adjustable pressure roller winding mechanism. Utility Model Content
[0004] The main purpose of the utility model is to provide a pressure-adjustable pressure roller winding mechanism, which can effectively solve the problems in the background technology.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] The pressure-adjustable pressure roller winding mechanism comprises a gantry, the bottom end of the gantry side wall is rotatably connected to a rotating shaft, the rotating shaft passes through one end of the gantry and is connected to an air-expanding shaft, a hydraulic cylinder is fixed to the inner top position of the gantry above the air-expanding shaft, an intermediate plate is fixed to the output end of the hydraulic cylinder, a roller frame is provided below the intermediate plate, the inside of the roller frame is rotatably connected to a pressure roller, sliding columns are fixed to both ends of the top of the roller frame, the outer walls of the sliding columns close to one end of the roller frame are sleeved with tension springs, threaded columns are fixed to both ends of the roller frame between the sliding columns, nuts are threadedly connected to the outer walls of the top ends of the threaded columns, and plate holes are drilled through the intermediate plate at the positions of the threaded columns and the sliding columns.
[0007] Preferably, one end of the sliding column away from the tension spring is respectively penetrated through the plate holes at matching positions and then slidably connected.
[0008] Preferably, the top of the tension spring is fixedly connected to the bottom of the middle plate, and the bottom of the tension spring is fixedly connected to the top of the roller frame.
[0009] Preferably, the threaded columns are respectively connected to the plate holes that match the positions, and the nuts are respectively located above the middle plates.
[0010] Preferably, sliding tubes are fixed at both ends of the gantry located at the hydraulic cylinder position, and sliding rods are fixed at both ends of the top of the middle plate located at the sliding tube position, and the sliding rods are respectively inserted into the interior of the sliding tube and slidably connected thereto.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] The hydraulic cylinder is fixed to the middle plate so that the middle plate maintains a constant height when the hydraulic cylinder is not started, and the tension of the tension spring forms a downward motion trajectory for the roller frame. When the roller frame descends, the threaded column will be driven to descend together. When the threaded column descends to a certain height, the nut threadedly connected to the threaded column at the top of the middle plate will touch the middle plate, making it impossible for the roller frame and the pressure roller to continue to descend, so that the middle plate can give a downward pressure and achieve the height adjustment effect through the lifting and lowering after the hydraulic cylinder is turned on. When the height of the middle plate rises, the pressure of the pressure roller on the winding material will decrease. When the height of the middle plate decreases, the pressure of the pressure roller on the winding material will increase. Therefore, the pressure roller has an adjustable pressure effect when the driving mechanism drives the rotating shaft and the air expansion shaft to wind. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Specifically, one end of the sliding column 8 away from the tension spring 9 is respectively penetrated with the plate hole 14 at the matching position and then slidably connected, the top of the tension spring 9 is respectively fixedly connected with the bottom of the middle plate 11, the bottom of the tension spring 9 is respectively fixedly connected with the top of the roller frame 5, the threaded column 6 is respectively penetrated with the plate hole 14 at the matching position, and the nut 7 is respectively located above the middle plate 11, so that the pressure generated by the tension spring 9 on the roller frame 5 can be adjusted by the hydraulic cylinder 10 to drive the middle plate 11 to rise and fall.
[0021] Specifically, sliding tubes 12 are fixed at both ends of the gantry 1 at the position of the hydraulic cylinder 10, and sliding rods 13 are fixed at both ends of the top of the middle plate 11 at the position of the sliding tube 12.

[0022] Working principle:
[0023] The sleeve to be rolled up is sleeved on the gas expansion shaft 3, and the end of the rotating shaft 2 away from the gas expansion shaft 3 is connected to the driving mechanism. This step is a publicly available prior art and will not be described in detail in this application. After the gas expansion shaft 3 works, the sleeve is limited and fixed, and then the rolling work is carried out.
