Description

Technical Field

[0001] The utility model relates to the technical field of squeezing roller assembly, in particular to a simple pressure assembly device for replacing a non-woven fabric squeezing roller. Background Art

[0002] In the production of copper strips, non-woven squeeze rollers play a vital role as key components in continuous cleaning equipment such as acid and alkali cleaning machines, cleaning machines, and air cushion furnaces. Their core structure typically consists of a roller constructed from several layers of annular non-woven fabric, a roller shaft that supports and transmits power, a gasket, and a locking nut. The roller is sleeved around the central periphery of the shaft; the gaskets are located at both ends of the shaft and fit snugly against the roller's end faces; the locking nut, located on the outside of the gasket, works in conjunction with the gasket to secure the relative position of the roller and shaft, ensuring stable operation. This structural design fully utilizes the porosity, good adhesion, and squeeze-out properties of the non-woven fabric, effectively improving the cleaning performance of the copper strips. However, as production continues, the non-woven rollers often experience severe wear due to frequent contact and friction with the copper strips, leading to a decline in roller performance and, in turn, leaving defects such as water marks and white spots on the copper strip surface, seriously affecting product quality.

[0003] Currently, the primary approach to addressing this problem is to replace the entire nonwoven squeeze roller, but this approach has numerous drawbacks. First, because the roller itself often remains in good condition after severe wear and tear, this complete replacement results in a significant waste of resources. Second, procuring a new squeeze roller is not only expensive but also time-consuming, making it difficult to meet the demands of modern industrial production for a rapid and continuous supply of high-quality copper strip.

[0004] Therefore, the prior art urgently needs an assembly device that can quickly and conveniently replace worn rollers without replacing the roller shaft. Utility Model Content

[0005] The utility model aims to overcome the deficiencies of the prior art and provides a simple pressure assembly device for replacing a non-woven fabric squeezing roller. When the squeezing roller is worn and cannot be used normally, the roller can be replaced quickly and conveniently, thereby effectively reducing production costs and avoiding waste of roller resources.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a simple pressure assembly device for replacing a non-woven fabric squeezing roller, comprising a pressure roller frame, a pressure mechanism and a supporting base plate, characterized in that the pressure roller frame is a frame structure, the supporting base plate is horizontally arranged at the bottom of the pressure roller frame, a first positioning hole is provided in the middle of the supporting base plate, the pressure mechanism is arranged at the top of the pressure roller frame, a clamping mechanism is provided on the lower side of the pressure mechanism, the pressure mechanism pushes the clamping mechanism to apply pressure in the direction of the first positioning hole, a second positioning hole is provided at the bottom of the clamping mechanism, and an axis accommodating cavity connected to the second positioning hole is provided in the middle of the clamping mechanism.

[0007] Furthermore, a supporting top plate is fixedly provided on the top of the pressure roller frame, and the pressure mechanism is fixedly provided on the lower side of the supporting top plate.

[0008] Specifically, the pressure-applying mechanism is a jack or a hydraulic cylinder, and the piston end of the jack or the hydraulic cylinder faces the first positioning hole and is coaxially arranged with the first positioning hole.

[0009] Specifically, the clamping mechanism includes an upper pressing plate, a lower pressing plate arranged parallel to and below the upper pressing plate, and a support rod arranged between the upper pressing plate and the lower pressing plate. The positioning hole is arranged in the middle of the lower pressing plate.

[0010] Working principle: When in use, remove the locking nuts, gaskets and worn rollers at both ends of the roller shaft in turn, put the new roller on the middle of the roller shaft, and put gaskets and screw locking nuts on both ends of the roller shaft in turn, so that the gaskets are close to the two end surfaces of the roller to preliminarily fix the relative position of the roller and the roller shaft; move the roller and roller shaft with the preliminarily fixed relative position to the lower support plate, and pass one end of the roller shaft and the locking nut at this end through the first positioning hole, so that the outer side of the gasket at this end fits with the upper side of the support plate, so as to achieve the positioning and stable support of the roller and roller shaft, and put the pressing mechanism on the other end of the roller shaft through the second positioning hole of the pressing mechanism , so that the lower side of the lower pressure plate and the upper side of the gasket at the other end fit each other. At this time, the roller shaft at the other end extends from the second positioning hole into the shaft accommodating cavity of the clamping mechanism, which is convenient for the clamping operation; operate the hydraulic cylinder or jack to make the piston end of the hydraulic cylinder or jack push the clamping mechanism to move downward, and the clamping mechanism pushes the gasket downward to squeeze the roller. Under the action of the extrusion force, the thickness of the roller decreases and the density increases, thereby achieving an increase in its hardness. Control the pressure of the hydraulic cylinder or jack until the water-squeezing roller of the required hardness is squeezed out; after the pressing is completed, tighten the adjusting nuts at both ends of the roller shaft toward the roller to fix the pressed roller.

[0011] Beneficial effects: The utility model makes full use of the elasticity and porosity of the non-woven fabric squeezing roller, and provides an efficient, convenient and economical non-woven fabric squeezing roller replacement solution. When the squeezing roller is worn and cannot be used normally, the roller can be quickly and conveniently replaced, thereby effectively reducing production costs and avoiding waste of roller resources; the device has a simple structure and is easy to operate. The roller can be replaced without complicated disassembly and installation processes, which can shorten equipment maintenance time and improve production efficiency; by using a hydraulic cylinder or a jack as a pressure mechanism, the pressure can be stably controlled to ensure uniform pressing of the roller, thereby improving the assembly quality of the squeezing roller. It is suitable for the assembly of non-woven fabric squeezing rollers of different models, and has good versatility and promotion and application value. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solutions and advantages of the present invention clearer and more understandable, the present invention is further described in detail below with reference to the accompanying drawings and technical solutions.

[0019] Example 1

[0020] See also Figure 1-Figure 5A simple pressure assembly device for replacing a non-woven fabric squeezing roller comprises a pressure roller frame 1, a pressure mechanism 2 and a supporting base plate 3. The pressure roller frame 1 is a frame structure, the supporting base plate 3 is horizontally arranged at the bottom of the pressure roller frame 1, and a first positioning hole 4 is provided in the middle of the supporting base plate 3. The pressure mechanism 2 is arranged at the top of the pressure roller frame 1, and a clamping mechanism is provided on the lower side of the pressure mechanism 2. The pressure mechanism 2 pushes the clamping mechanism to apply pressure toward the first positioning hole 4. A second positioning hole 5 is provided at the bottom of the clamping mechanism, and an axis accommodating cavity 6 connected to the second positioning hole 5 is provided in the middle of the clamping mechanism.

[0021] The pressing mechanism can be movably arranged, or can be fixedly connected or detachably connected to the pressing mechanism 2; when the pressing mechanism is movably arranged, the pressing mechanism can be arbitrarily moved relative to all components of the device, so that the pressing mechanism can be sleeved on the end of the roller shaft 11 through the second positioning hole 5 of the pressing mechanism; when the pressing mechanism is fixedly connected or detachably connected to the pressing mechanism 2, the pressing mechanism can be controlled to move by manipulating the pressing mechanism 2, thereby achieving the sleeved position of the pressing mechanism on the end of the roller shaft 11 through the second positioning hole 5 of the pressing mechanism;

[0022] The shaft accommodating cavity 6 is used to accommodate the roller shaft 11 on the upper side of the roller 12 and protrude from the outside of the roller 12 when applying pressure to the roller 12, so that the lower pressure plate 9 can directly contact the gasket 13 on the upper side of the roller 12, so that the pressure applied by the pressure mechanism 2 can directly act on the gasket 13 and the roller 12 through the clamping mechanism; the height of the shaft accommodating cavity 6 is greater than the height of the roller shaft 11 on the upper side of the roller 12 and protrude from the outside of the roller 12, and is used to avoid the upper end of the roller shaft 11 from conflicting with the lower pressure plate 9 and interfering with the downward pushing action of the clamping mechanism during the pressure process.

[0023] Furthermore, a supporting top plate 7 is fixedly provided on the top of the pressure roller frame 1 to facilitate the installation and fixation of the pressure mechanism 2. The pressure mechanism 2 can be fixed to the lower side of the supporting top plate 7 by bolts.

[0024] Specifically, the pressure mechanism 2 is a jack or a hydraulic cylinder, the piston end of which faces the first positioning hole 4 and is coaxially arranged with the first positioning hole 4. This structural design ensures that all parts of the roller 12 are evenly stressed during the pressure operation, ensuring uniform density and hardness of the roller 12 after pressing, and significantly improving the performance and service life of the assembled water squeeze roller.

[0025] Specifically, the clamping mechanism includes an upper pressing plate 8, a lower pressing plate 9 arranged parallel to the lower portion of the upper pressing plate 8, and a support rod 10 arranged between the upper pressing plate 8 and the lower pressing plate 9. The positioning hole is arranged in the middle of the lower pressing plate 9.

[0026] When in use, remove the locking nuts 14, gaskets 13 and worn roller 12 at both ends of the roller shaft 11 in turn, put the new roller 12 on the middle of the roller shaft 11, and put gaskets 13 and screw locking nuts 14 on both ends of the roller shaft 11 in turn, so that the gaskets 13 are close to the two end surfaces of the roller 12 to preliminarily fix the relative position of the roller 12 and the roller shaft 11; move the roller 12 and roller shaft 11 whose relative positions are preliminarily fixed to the supporting base plate 3, and pass one end of the roller shaft 11 and the locking nut 14 at this end through the first positioning hole 4, so that the outer side surface of the gasket 13 at this end is in contact with the upper side surface of the supporting base plate 3, so as to achieve the positioning and firm support of the roller 12 and the roller shaft 11, and the pressing mechanism is tightened through the second positioning hole 5 of the pressing mechanism It is sleeved on the other end of the roller 11 so that the lower side surface of the lower pressure plate 9 and the upper side surface of the gasket 13 at the other end fit each other. At this time, the roller 11 at the other end extends from the second positioning hole 5 into the shaft accommodating cavity 6 of the clamping mechanism, which is convenient for the clamping operation; operate the hydraulic cylinder or jack so that the piston end of the hydraulic cylinder or jack pushes the clamping mechanism to move downward, and the clamping mechanism pushes the gasket 13 downward to squeeze the roller 12. Under the action of the extrusion force, the thickness of the roller 12 decreases and the density increases, thereby increasing its hardness. The pressure applied by the hydraulic cylinder or jack is controlled until a water-squeezing roller of the required hardness is squeezed out; after the pressing is completed, tighten the adjusting nuts at both ends of the roller 11 toward the roller 12 to fix the pressed roller 12.
