Description

Technical Field

[0001] The utility model relates to the technical field of papermaking equipment, in particular to a shoe press holding device. Background Art

[0002] A shoe press is a device used to apply pressure in industries such as papermaking and printing. During the papermaking process, it primarily compresses the paper web. Using components like shoe plates and pressure rollers, it applies uniform and continuous pressure to the paper web, squeezing out moisture and improving its density and strength. Its operating principle is powered by a hydraulic or pneumatic system. For example, in a hydraulic shoe press, hydraulic oil is pumped into the shoe plate's pressure chamber, creating a pressure perpendicular to the paper web. The shoe plate is typically a long, rectangular component, its length matching the paper machine's web width, providing uniform pressure across the entire width of the paper web. During operation, the paper web passes between the shoe plate and opposing pressure rollers. The pressure squeezes moisture out of the web and drains it through a drainage system, while simultaneously compacting the web's fiber structure.

[0003] When the hydraulic cylinder pressurizes the shoe plate through the pressurizing piston, the pressurizing piston and the shoe plate are fixed by bolts. This fixed connection method makes the adaptability of the curvature of the shoe plate and the curvature of the lower roller when pressurized depend on the processing and installation accuracy of the equipment. The shoe plate has no room for adjustment, which increases the risk of damage to the boot sleeve. In addition, when the center beam of the support of the pressurizing piston is deformed, the deformation will affect the shoe plate, thereby affecting the operation effect of the equipment.

[0004] Therefore, a shoe pressing device is urgently needed to solve the above problems. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example 1

[0021] See also Figure 1-Figure 5 , a shoe pressure holding device shown in the figure includes a roller shell 101 and an I-shaped shoe beam 102 arranged in the roller shell 101, a shoe pressure plate 103 is provided on the side of the shoe beam 102 close to the upper pressure roller, and also includes a hydraulic oil cylinder 2 arranged on the side of the shoe beam 102 close to the shoe pressure plate 103, the output end of the hydraulic oil cylinder 2 is connected to the output rod 3, the end of the output rod 3 away from the hydraulic oil cylinder 2 is connected to two first mounting plates 4 through a connecting component, one end of the two first mounting plates 4 is connected to the shoe pressure plate 103, and the shoe beam 102 is provided with an adaptation component for adapting the shoe pressure plate 103;

[0022] It should be noted here that: the shoe pressure plate 103 is rotatably connected to the output rod 3 of the hydraulic cylinder 2, so that under the extrusion of pressure, the shoe pressure plate 103 will make an appropriate rotational deviation to align with the center of the roller to prevent pressure deviation. Therefore, under the relative swinging action between the hydraulic cylinder 2 and the shoe pressure plate 103, it is ensured that the shoe pressure plate 103 can self-adjust according to the dynamic conditions of the pressure zone, thereby preventing the risk of shutdown caused by deformation of the shoe pressure plate 103 and improving the fit between the shoe pressure plate 103 and the outer diameter of the roller. The structure is simple and effective, and reduces manufacturing, installation and maintenance costs.

[0023] See also Figure 3 The adaptation component shown in the figure includes two adaptation tubes 501 arranged on the side of the shoe beam 102 close to the shoe pressure plate 103. The two adaptation tubes 501 are symmetrically arranged about the hydraulic cylinder 2. The two adaptation tubes 501 are slidably connected to the adaptation rods 502. The two adaptation rods 502 and the adaptation tubes 501 are respectively connected to the shoe pressure plate 103 and the shoe beam 102 through the mounting assembly. The ends of the two adaptation rods 502 away from the shoe pressure plate 103 are located in the adaptation tube 501 and are fixedly connected to the adaptation plate 503. The side walls of the two adaptation rods 502 located inside the adaptation tube 501 are sleeved with first springs 504. The two ends of the two first springs 504 are respectively connected to the adaptation tube 501 and the adaptation plate 503.

[0024] It should be noted here that: by adapting to the setting of the component, it is used to provide elastic support for the shoe pressure plate 103 and can adaptively deform and reset.

[0025] See also Figure 4 The mounting assembly shown in the figure includes a circular plate 601 fixedly connected to one end of the adaptation rod 502 close to the shoe pressure plate 103, and a fixed plate 602 is fixedly connected to the side of the circular plate 601 away from the adaptation rod 502. The fixed plate 602 is connected to two second mounting plates 603 through a connecting assembly, and one end of the two second mounting plates 603 is connected to the shoe pressure plate 103;

[0026] It should be noted here that: by setting the mounting assembly, it is convenient to form a detachable connection between the adaption rod 502 and the shoe pressure plate 103.

[0027] Working principle: Since the shoe pressure plate 103 is an arc-shaped plate, its arc shape is consistent with the outer diameter of the roller. Under the pressure of the hydraulic cylinder 2, the shoe pressure plate 103 is pressed against the roller, thereby realizing the dehydration of the paper sheet, and when the shoe pressure plate 103 is against the roller, since the shoe pressure plate 103 is rotatably connected to the output rod 3 of the hydraulic cylinder 2, it will make appropriate rotational deviation under the extrusion of pressure to align it with the center of the roller to prevent pressure deviation, so that under the relative swinging action between the hydraulic cylinder 2 and the shoe pressure plate 103, it is ensured that the shoe pressure plate 103 can self-adjust according to the dynamic conditions of the pressure zone, thereby preventing the risk of shutdown caused by deformation of the shoe pressure plate 103 and improving the fit between the shoe pressure plate 103 and the outer diameter of the roller. The structure is simple and effective, reducing manufacturing, installation and maintenance costs.

[0028] Example 2

[0029] See also Figure 5 This embodiment further explains Example 1. The connecting assembly shown in the figure includes a T-shaped rod 701. A mounting cavity 702 is defined on one side wall of the T-shaped rod 701. The mounting cavity 702 is connected to two symmetrically arranged connecting rods 703 via an extrusion assembly. The mounting cavity 702 is provided with a driving assembly for driving the two connecting rods 703.

[0030] It should be noted here that: by setting the connecting assembly, a detachable connection is formed between the adaptation rod 502 and the shoe pressure plate 103, thereby facilitating subsequent disassembly and maintenance.

[0031] See also Figure 5 The extrusion assembly shown in the figure includes a fixing ring 801 fixedly connected to the connecting rod 703 located on the side wall of the installation cavity 702, and a second spring 802 is sleeved on the side wall of the connecting rod 703. The two ends of the second spring 802 are respectively connected to the fixing ring 801 and the inner wall of the installation cavity 702;

[0032] It should be noted here that the extrusion assembly is provided to drive the two connecting rods 703 to reset.

[0033] See also Figure 5 The driving assembly shown in the figure includes a T-shaped threaded rod 901 threadedly connected to the inner wall of the installation cavity 702. One end of the T-shaped threaded rod 901 located inside the installation cavity 702 is rotatably connected to a tapered body 902. The ends of the two connecting rods 703 that are close to each other are slidably connected to the tapered body 902. The ends of the tapered body 902 that are away from the T-shaped threaded rod 901 are connected to the bottom wall of the installation cavity 702 through a guide sleeve 903.

[0034] It should be noted here that the drive assembly is configured to drive the two opposing connecting rods 703 to move away from each other.

[0035] Working Principle: When connecting the output rod 3 of the hydraulic cylinder 2 or the adaptable rod 502 to the shoe pressure plate 103, first place the fixed plate 602 at one end of the adaptable rod 502 between the two second mounting plates 603, and then pass one end of the T-shaped rod 701 through the connecting holes on the two second mounting plates 603 and the fixed plate 602;

[0036] After one end of the T-shaped rod 701 passes through the second mounting plate 603, the T-shaped threaded rod 901 is rotated, and the conical body 902 is driven to move in the mounting cavity 702 under the action of the threaded engagement transmission and the guiding action of the guide sleeve 903. During the movement of the conical body 902, the two connecting rods 703 will be pushed, so that the two connecting rods 703 are moved away from each other and out of the mounting cavity 702. After the two connecting rods 703 are moved out of the mounting cavity 702, the insertion of the T-shaped rod 701 can be limited under its blocking action, thereby forming a detachable connection for the adaptation rod 502 and the shoe pressure plate 103.
