[0002] Paper presses are key equipment in the papermaking process. Their main function is to mechanically squeeze and dewater wet paper webs. The wet paper webs are pressed between the press rolls, and the water is squeezed out through the blankets. This device can reduce the moisture content of the paper, increase the paper density, strength, and surface smoothness, and improve the paper quality, so that the paper meets the requirements of subsequent drying and calendering processes. It plays an important role in improving paper quality and production efficiency in the papermaking process.

[0003] Most existing paper pressing devices have fixed pressure or limited adjustment range, which cannot be adapted to paper with different textures and thicknesses. This can easily lead to crushing and damage to soft paper, or insufficient dehydration of hard paper, making it difficult to ensure the consistency of paper quality and affecting subsequent processing and product quality. Therefore, those skilled in the art have provided a paper pressing device with adjustable pressure to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a pressure-adjustable paper press device. This device can be flexibly adjusted according to the characteristics of different papers, making it highly flexible.

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

[0006] A pressure-adjustable paper press device includes a main body, a pressing mechanism at the upper part of the main body, an auxiliary mechanism at the middle part of the main body, a collection trough at the bottom of the main body, a filter screen at the upper end of the collection trough, and a stirring mechanism at the lower end of the main body.

[0007] The pressing mechanism includes a hydraulic cylinder, two slide rails, a movable seat, and a first pressure roller. A first motor is fixedly installed on one side of the movable seat. The stirring mechanism includes a third motor. A rotating rod is fixedly installed at the output end of the third motor, and a stirring blade is fixedly installed at the upper end of the rotating rod.

[0008] Furthermore, the main body of the device includes a base, a drain pipe is fixedly installed at the lower end of one side of the front of the base, and a fixing frame is fixedly installed at the upper end of the base.

[0009] Furthermore, the two slide rails are respectively fixedly installed on the upper part of the inner wall on both sides of the main body of the device, and both sides of the movable seat are slidably connected to the slide rails.

[0010] Furthermore, the output end of the hydraulic cylinder is fixedly connected to the movable seat, and both sides of the first pressure roller are rotatably connected to the movable seat.

[0011] Furthermore, the output end of the first motor is fixedly connected to one side of the first pressure roller.

[0012] Furthermore, the auxiliary mechanism includes a second pressure roller and two mounting seats, one of which is fixedly equipped with a second motor on one side.

[0013] Furthermore, both sides of the second pressure roller are rotatably connected to the mounting base, and the output end of the second motor is fixedly connected to one side of the second pressure roller.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model proposes a pressure-adjustable paper press device. The paper press device precisely controls the pressing pressure through the hydraulic cylinder of the pressing mechanism, and can be flexibly adjusted according to the characteristics of different papers. For softer papers, the pressure is reduced to prevent crushing, while for harder papers, the pressure is increased to improve dewatering efficiency. This precise adjustment ensures that all types of papers can obtain the best pressing effect and improve product quality. At the same time, the coordinated rotation design of the first and second pressure rollers makes the paper evenly stressed during the pressing process, further enhancing the dewatering effect, reducing the paper moisture content, providing good conditions for subsequent processing, and effectively improving production efficiency and economic benefits.

[0016] 2. This utility model proposes a pressure-adjustable paper press device, which achieves environmentally friendly treatment of press waste liquid through the cooperation of a collection tank, a filter screen, and a stirring mechanism. The filter screen intercepts paper fragments and other impurities, preventing pipe blockage. The stirring mechanism fully stirs the waste liquid after adding the reactant to the collection tank, accelerating the chemical reaction between the reactant and harmful substances in the waste liquid, effectively decomposing organic matter or precipitating heavy metal ions. The pretreated waste liquid is easier to further treat, meets environmental emission standards, reduces environmental pollution, embodies the concept of green production, and provides strong support for the sustainable development of enterprises.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1-4 An embodiment of this utility model is provided: a pressure-adjustable paper pressing device, including a device body 1, a pressing mechanism 2 is provided on the upper part of the device body 1, an auxiliary mechanism 3 is provided in the middle of the device body 1, a collection trough 4 is provided at the bottom of the device body 1, a filter screen 5 is provided at the upper end of the collection trough 4, and a stirring mechanism 6 is provided at the lower end of the device body 1.

[0025] Specifically, the main body 1 serves as the basic frame, supporting various functional mechanisms and providing the pressing operation space. The pressing mechanism 2 is the core component for pressure regulation, achieving controllable pressure pressing of the paper through hydraulic drive. The auxiliary mechanism 3 works in conjunction with the pressing mechanism 2 to improve the paper pressing effect. The collection tank 4 and the filter screen 5 are responsible for collecting and filtering the waste liquid generated during the pressing process. The stirring mechanism 6 stirs the mixture after adding the reactant to the collection tank 4, promoting full contact between the reactant and the waste liquid, accelerating the decomposition or precipitation of harmful substances in the waste liquid, realizing the pretreatment of the waste liquid, and preparing for subsequent environmentally friendly discharge.

[0026] Reference Figure 1 , Figure 2The main body 1 of the device includes a base 102. A drain pipe 101 is fixedly installed on the lower end of one side of the front of the base 102. A fixed frame 103 is fixedly installed on the upper end of the base 102. The pressing mechanism 2 includes a hydraulic cylinder 201, two slide rails 202, a movable seat 203 and a first pressure roller 204. A first motor 205 is fixedly installed on one side of the movable seat 203. The two slide rails 202 are respectively fixedly installed on the upper end of the inner walls on both sides of the main body 1. Both sides of the movable seat 203 are slidably connected to the slide rails 202. The output end of the hydraulic cylinder 201 is fixedly connected to the movable seat 203. Both sides of the first pressure roller 204 are rotatably connected to the movable seat 203. The output end of the first motor 205 is fixedly connected to one side of the first pressure roller 204.

[0027] Specifically, in the main body 1 of the device, the base 102 provides stable support for the device, the drain pipe 101 is used to discharge the waste liquid in the collection tank 4, and the fixed frame 103 provides the mounting base for the pressing mechanism 2. In the pressing mechanism 2, the hydraulic cylinder 201 drives the moving seat 203 to slide up and down along the slide rail 202 through telescopic drive, thereby adjusting the position of the first pressure roller 204 and the pressure applied to the paper. The first motor 205 drives the first pressure roller 204 to rotate, which works with the second pressure roller 301 to crush and dewater the paper. The hydraulic cylinder 201 is connected to a pressure sensor to monitor the pressure of the pressure roller in real time and realize closed-loop regulation through the control system.

[0028] Reference Figure 3 , Figure 4 The auxiliary mechanism 3 includes a second pressure roller 301 and two mounting seats 303. A second motor 302 is fixedly installed on one side of one of the two mounting seats 303. Both sides of the second pressure roller 301 are rotatably connected to the mounting seats 303. The output end of the second motor 302 is fixedly connected to one side of the second pressure roller 301. The stirring mechanism 6 includes a third motor 601. A rotating rod 602 is fixedly installed on the output end of the third motor 601. A stirring blade 603 is fixedly installed on the upper end of the rotating rod 602.

[0029] Specifically, in the auxiliary mechanism 3, the second pressure roller 301 and the first pressure roller 204 form a rolling fit to enhance the paper dewatering effect. The third motor 601 of the stirring mechanism 6 drives the rotating rod 602 and the stirring blade 603 to rotate. After adding the reactant into the collection tank 4, the mixture of waste liquid and reactant is fully stirred to accelerate the chemical reaction process and enable the reactant to better decompose or precipitate harmful substances in the waste liquid.

[0030] Working Principle: When using this paper press device, first place the paper to be pressed above the second pressure roller 301. Start the second motor 302 to drive the second pressure roller 301 to rotate, moving the paper between the first pressure roller 204 and the second pressure roller 301. According to the characteristics of the paper and the pressing requirements, adjust the position of the moving seat 203 on the slide rail 202 by controlling the extension and retraction of the hydraulic cylinder 201, thereby adjusting the distance between the first pressure roller 204 and the second pressure roller 301 to achieve precise adjustment of the paper pressing pressure. Start the first motor 205 to drive the first pressure roller 204 to rotate, rotating synchronously in the opposite direction to the second pressure roller 301, crushing the paper passing between them. During the crushing process, the water in the paper is squeezed out and flows into the collection tank 4 through the filter screen 5. The filter screen 5 intercepts paper fragments and other impurities, ensuring that the liquid entering the collection tank 4 is relatively clean. When the waste liquid in the collection tank 4 reaches a certain amount, it can be discharged into the collection tank. Add a reactant to the collection tank 4. The type of reactant can be selected according to the composition of the waste liquid, such as an oxidant for decomposing organic matter or a flocculant for precipitating heavy metal ions. Start the third motor 601 to drive the rotating rod 602 and the stirring blade 603 to rotate, stirring the mixture of waste liquid and reactant. During the stirring process, the reactant and waste liquid come into full contact, accelerating the decomposition or precipitation reaction of harmful substances. The stirring time can be adjusted according to the type of reactant and the waste liquid treatment requirements to ensure that the reaction is fully carried out. After the reaction is completed, open the valve of the drain pipe 101 to discharge the treated waste liquid from the device. The sediment can be cleaned periodically by disassembling the device to maintain its normal operation. If it is necessary to continue pressing other types of paper, the above operation can be repeated. Adjust the pressing pressure again according to the paper condition, and when the waste liquid in the collection tank 4 reaches a certain amount, add reactant again for stirring treatment to achieve environmentally friendly treatment of waste liquid generated during the pressing process.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
