Description

Technical Field

[0001] This utility model relates to the field of pressure roller cleaning technology, and more specifically, to an online cleaning device for hydraulic rollers. Background Technology

[0002] Viscose fiber remains a widely used chemical fiber, and its excellent performance and market demand make it a target for continuous development by enterprises. With continuous advancements in production technology, high efficiency, high quality, and low cost remain the fundamental pursuits and core of enterprise development. Continuously improving production technology is essential to enhancing enterprise competitiveness. In viscose fiber production, the key equipment in the solution processing stage—the press—has a significant impact on production costs due to its stability and service life. The press's function is to dry the pulp output from the impregnation process, squeezing out excess alkali and obtaining the required alkali cellulose. With continuous material operation, current production conditions inevitably lead to pulp and liquid leakage, causing scale buildup. Furthermore, the short cellulose and impurities clog the mesh on the press rollers, preventing proper alkali discharge and reducing equipment efficiency. Alkali scale can harden, and current cleaning technologies are relatively outdated, mainly relying on manual high-pressure water jet washing. There is significant room for improvement in cleaning effectiveness, efficiency, and labor costs.

[0003] In viscose fiber production, the main raw material is pulp, which is further divided into hard pulp and soft pulp, and must be mixed in a certain proportion. Currently, mainstream viscose fiber manufacturers do not use a single specification or brand of pulp, and their blending and impregnation processes also differ. These differences result in significant variations in the composition of the impregnated pulp. Short fibers and sugar-containing impurities can clog the internal structure of the press rollers (alkali filter holes, flow channels, and U-grooves) during pressing. This blockage leads to wet strips or wet material on the pressed pulp sheet, affecting subsequent aging and ultimately impacting viscose quality. Therefore, cleaning the press rollers is necessary.

[0004] Currently, existing technology involves periodically stopping the machine and manually cleaning the pressure rollers with a high-pressure water gun. However, manual cleaning of the pressure rollers has its shortcomings. It is difficult for personnel to operate. Due to the relatively high pressure of the high-pressure water gun, the reaction force is large, making manual cleaning laborious. The cleaning effect is greatly affected by the skill level of the personnel, and there are certain safety hazards. During cleaning, the limited space makes personnel movement difficult, which also poses safety hazards. In addition, the cleaning efficiency is low. Furthermore, manual cleaning is mostly a single cleaning, resulting in unsatisfactory cleaning effects.

[0005] Therefore, we have made improvements to this and proposed an online cleaning device for hydraulic rollers. Utility Model Content

[0006] The purpose of this invention is to address the problem that the efficiency and effectiveness of manual handheld water gun cleaning of pressure rollers are currently unsatisfactory.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] The original hydraulic roller online cleaning device was developed to improve the above-mentioned problems.

[0009] The present invention is as follows:

[0010] The device includes a press, which contains a pressure roller and a mounting frame. A first screw is rotatably connected to the mounting frame, and a first cleaning mechanism is mounted on the first screw.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, this embodiment proposes an online cleaning device for hydraulic rollers, including a press 1, a press roller body 2 inside the press 1, a mounting frame 3 on the press 1, a first screw 4 rotatably connected inside the mounting frame 3, a first cleaning mechanism 5 on the first screw 4, one end of the first screw 4 penetrating the side wall of the mounting frame 3 and fixedly connected to a handwheel 6, a second screw 7 on the lower side of the first screw 4, the second screw 7 rotatably connected to the mounting frame 3, a second cleaning mechanism 8 on the second screw 7, and the ends of both the first screw 4 and the second screw 7 away from the handwheel 6 penetrating the mounting frame 3 and fixedly connected to meshing gears 9. A water supply mechanism 10 is provided on one side of the frame 3. By rotating the handwheel 6, the first screw 4 is driven to rotate. Since the ends of the first screw 4 and the second screw 7 away from the handwheel 6 are connected by gear 9, the rotation of the first screw 4 will drive the second screw 7 to rotate synchronously in the opposite direction. This will cause the first cleaning mechanism 5 and the second cleaning mechanism 8 to move synchronously in the opposite direction. Thus, the surface of the pressure roller body 2 can be cleaned on both sides at once, which significantly improves the cleaning effect. There is no need for the operator to hold a water gun for cleaning, which improves the cleaning effect, extends the service life of the pressure roller, solves the inconvenience of manual cleaning operation, and also reduces the safety risks of operation.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, in a preferred embodiment, based on the above method, the first cleaning mechanism 5 further includes a movable block 501 threadedly connected to the first screw 4. Support plates 502 are fixedly connected to the left and right side walls of the movable block 501, and a water spray pipe 503 is fixedly connected between the support plates 502. First nozzles 504 are fixedly connected to both ends of the bottom of the water spray pipe 503. When the first screw 4 rotates, the movable block 501 will move linearly on the first screw 4. The movable block 501 drives the support plates 502 to move, and the support plates 502 drive the water spray pipe 503 to move. The first nozzles 504 at the bottom of the water spray pipe 503 move accordingly, thereby spraying water to clean the surface of the pressure roller body 2.

[0031] like Figure 1 , Figure 2 and Figure 3As shown, in a preferred embodiment, based on the above method, the second cleaning mechanism 8 further includes a shift block 801 threadedly connected to the second screw 7. A water supply box 802 is fixedly connected to the end of the shift block 801. Second nozzles 803 are fixedly connected to the left and right side walls of the water supply box 802. A slider 804 is fixedly connected to the side wall of the water supply box 802 away from the shift block 801. A guide rod 805 is slidably connected inside the slider 804. The two ends of the guide rod 805 are fixedly connected to the mounting bracket 3 respectively. A connecting pipe 806 is fixedly connected to the lower end face of the water supply box 802. When the second screw 7 rotates, the shift block 801 will move linearly. The shift block 801 drives the water supply box 802 to move, and the second nozzles 803 on the water supply box 802 move accordingly to spray water to clean the surface of the pressure roller body 2. The connecting pipe 806 is used to connect to a water source.

[0032] like Figure 1 , Figure 3 , Figure 5 and Figure 6As shown, in a preferred embodiment, based on the above method, the rewinding water supply mechanism 10 further includes a connecting rod 1001 fixed to the side wall of the mounting frame 3 near the gear 9. A column 1002 is fixedly connected to the end of the connecting rod 1001. A base box 1003 is fixedly connected to both the upper and lower ends of the column 1002. A rotating shaft 1004 is rotatably connected to the center of the base box 1003. A coil spring 1005 is provided inside the base box 1003. The inner end of the coil spring 1005 is fixedly connected to the rotating shaft 1004. The outer end of the spring 1005 is rotatably connected to the base box 1003 via a connecting shaft. A reel 1006 is fixedly connected to the top of the rotating shaft 1004. An assembly frame 1007 is fixedly connected to the outer side wall of the base box 1003. A water supply pipe 1008 is fixedly connected to the end of the assembly frame 1007. The inner end of the water supply pipe 1008 passes through the reel 1006 and extends into the interior. A connecting pipe 1009 is fixedly connected to the inner end of the water supply pipe 1008. The end of the connecting pipe 1009 passes through the reel 1006 and extends to the outside. The portion of pipe 1009 that contacts reel 1006 is fixedly connected to reel 1006. The end of the upper connecting pipe 1009 is fixedly connected to the inlet end of water spray pipe 503, and the end of the lower connecting pipe 1009 is fixedly connected to the inlet end of connecting pipe 806. A tee pipe 1010 is fixedly connected between the upper and lower water supply pipes 1008. Water supply pipe 1008 introduces water, and the tee pipe 1010 distributes the water to the upper and lower water supply pipes 1008. The inner end of water supply pipe 1008 is connected to reel 1006. The internal connecting tube 1009 is pulled when the first cleaning mechanism 5 and the second cleaning mechanism 8 move. The connecting tube 1009 is a rubber hose that can be wound up as the mechanism moves. The coil spring 1005 inside the reel 1006 generates elastic force when the connecting tube 1009 is pulled. When the cleaning mechanism resets, the elastic force of the coil spring 1005 will cause the reel 1006 to automatically wind up the connecting tube 1009, ensuring that the connecting tube 1009 is always at a suitable length and will not be tangled or overstretched.

[0033] like Figure 2 , Figure 3 and Figure 5 As shown, in a preferred embodiment, based on the above method, the connecting pipe 1009 is further made of rubber hose, and the inside of the reel 1006 is designed as a hollow structure; the connecting pipe 1009 is made of rubber hose, which has good flexibility and extensibility, can adapt to the movement of the cleaning mechanism, and will not be damaged due to stretching.

[0034] like Figure 1 and Figure 3As shown, in a preferred embodiment, based on the above method, the upper end face of the mounting bracket 3 is further provided with a strip-shaped opening 11 that matches the moving block 501; the strip-shaped opening 11 facilitates the moving block 501 to make linear movement within the strip-shaped opening 11 under the drive of the first screw 4, thereby realizing the movement of the first cleaning mechanism 5.

[0035] Specifically, when using the Benyuan hydraulic roller online cleaning device: First, connect the external water supply equipment to the water supply end of the three-way pipe 1010. Water is introduced into the water supply pipe 1008 through the three-way pipe 1010. The water in the water supply pipe 1008 flows into the spray pipe 503 and the connecting pipe 806 respectively. The water flowing into the spray pipe 503 will be sprayed out through the first nozzle 504. The water flowing into the connecting pipe 806 will enter the water supply box 802, and then be sprayed out through the second nozzle 803. By turning the handwheel 6, the first screw 4 is driven to rotate. Since the ends of the first screw 4 and the second screw 7 away from the handwheel 6 are connected by gear 9, the rotation of the first screw 4 will drive the second screw 7 to rotate synchronously in the opposite direction. When the first screw 4 rotates, the moving block 501 will move linearly on the first screw 4. The moving block 501 drives the support plate 502 to move. When the support plate 502 moves, the water spray pipe 503 moves, and the first nozzle 504 at the bottom of the water spray pipe 503 moves accordingly, thereby spraying water to clean the surface of the pressure roller body 2. When the second screw 7 rotates, the shift block 801 will move linearly, and the shift block 801 will move the water supply box 802. The second nozzle 803 on the water supply box 802 moves accordingly to spray water to clean the surface of the pressure roller body 2. When the water spray pipe 503 and the connecting pipe 806 move, they pull the connecting pipe 1009. The coil spring 1005 inside the reel 1006 generates elastic force when the connecting pipe 1009 is pulled. When it returns to its original position, the elastic force of the coil spring 1005 will cause the reel 1006 to automatically wind up the connecting pipe 1009, ensuring that the connecting pipe 1009 is always at a suitable length and will not be tangled or overstretched. A single operation can achieve two cleanings on the surface of the pressure roller body 2, which significantly improves the cleaning effect.

[0036] All technical features in this embodiment can be freely combined according to actual needs.

[0037] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
