Description

Technical Field

[0001] This application belongs to the field of press roller technology, and particularly relates to a press roller. Background Technology

[0002] In papermaking and related production fields, press rolls are key equipment for material dehydration, compaction and other processing. Their operational stability directly affects production efficiency and product quality.

[0003] In the long-term use of existing press rolls, the lubrication effect of the bearing parts has a significant impact on the equipment life. The bearing chamber of traditional press rolls usually only has a single oil passage or a simple oil injection structure. It is difficult for the lubricating grease to be evenly distributed in the bearing chamber, which easily leads to local insufficient lubrication, resulting in accelerated bearing wear and increased equipment maintenance frequency and cost.

[0004] Meanwhile, during operation, excess moisture and impurities easily adhere to the surface of the press roller. If not cleaned in time, this will affect the pressing effect and even contaminate the processed materials. Existing scraping components for cleaning rely on simple structures for position adjustment, making it difficult to accurately control the fit between the scraper and the press roller surface, resulting in inconsistent scraping effects. Furthermore, the design of the impurity collection structure after scraping is not reasonable enough, leading to scattering and affecting the cleanliness of the production environment. Improvements are needed in these areas. Utility Model Content

[0005] The purpose of this application is to provide a press roller that can solve the above-mentioned problems.

[0006] The purpose of this application is to provide a press roller, comprising: The frame has bearing seats at both ends of its upper part for rotatably supporting the press rolls, and oil injection channels are provided on the outside of the bearing seats; The first oil passage is arranged in a ring inside the bearing housing, and its left and right sides are respectively connected to the first auxiliary oil passage and the second auxiliary oil passage. A support frame is set on both sides of the press roller. A collection groove is set at the lower end of one side of the support frame. A connecting arm is installed on one side of the support frame. A fixed seat is installed at the upper end of the connecting arm on the side away from the support frame. An adjusting screw is connected to the fixed seat. A scraper is movably connected to one side of the adjusting screw. The first and second auxiliary oil passages are each composed of multiple arc-shaped grooves connected end to end. The corresponding arc-shaped grooves are connected to the first oil passage, and an oil injection device is connected to the oil injection channel.

[0007] The aforementioned press roll uses a frame as its overall supporting foundation. The bearing seats at both ends of the frame provide rotatable support for the press roll, ensuring stable rotation during operation. The oil injection channel on the outer side of the bearing seat provides an entry path for lubricating grease. This works in conjunction with the internally annular first oil passage, and a first and second auxiliary oil passage connected to the first oil passage. The two auxiliary oil passages consist of multiple interconnected arc-shaped grooves, with the connecting points of the arc-shaped grooves communicating with the first oil passage. This allows the lubricating grease to be evenly distributed within the bearing seat through the cooperation of the main and auxiliary oil passages. This solves the problem of uneven lubricating grease distribution and insufficient local lubrication leading to accelerated bearing wear in the press roll bearing chamber, thus effectively extending the bearing's service life.

[0008] Meanwhile, the support frames on both sides of the press roller provide a stable mounting base for the scraping and collecting components. The collection groove at the lower end of one side can collect the scraped impurities, preventing them from scattering and polluting the production environment, thus improving the problem of impurity scattering caused by the unreasonable design of the existing collection structure. In addition, the connecting arm on one side of the support frame connects to the fixing plate. The adjusting screw on the fixing plate can flexibly adjust the position of the movable scraper, so that the scraper can maintain a suitable fit with the surface of the press roller according to actual needs, improving the scraping effect and solving the problems of inaccurate position adjustment and unstable scraping effect of the existing scraping components.

[0009] Furthermore, the oil injection channel is connected to the first oil passage.

[0010] In this application, the oil injection channel is connected to the first oil passage, which can ensure that the lubricating grease can directly enter the first oil passage, reduce the loss on the grease delivery path, improve the grease utilization rate, and avoid the problem of low lubrication efficiency caused by the unreasonable existing oil injection path.

[0011] Furthermore: the oil injection device includes: A storage container for storing grease, with an oil outlet at the bottom; A sealing end cap is provided on the upper part of the storage container, and a linear actuator is provided on the sealing end cap; The linear actuator's telescopic rod passes through the sealed end cap and extends into the storage container, where a pressure plate is connected at the end.

[0012] In the oil injection device, the storage container is used to store lubricating grease to ensure a continuous grease supply; the sealing end cap forms an effective seal on the storage container to prevent external impurities from entering and contaminating the grease; the linear actuator drives the pressure plate to move within the storage container by driving the telescopic rod, thereby actively pushing the grease, which solves the problem of untimely oil supply caused by the existing oil injection device relying on gravity oil supply, and ensures that the grease can be stably delivered to the oil injection channel. At the same time, the linear actuator here can be an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder.

[0013] Furthermore, the storage container is provided with an outlet at the bottom, and the inner diameter of the storage container gradually decreases from the outlet.

[0014] The outlet installed at the bottom of the storage container has a gradually decreasing inner diameter towards the outlet, which can guide grease to accumulate at the outlet, reduce grease residue in the container, improve grease utilization, and avoid waste caused by grease that is difficult to drain from the bottom of the container.

[0015] Furthermore, a movable nut is threadedly connected to one side of the adjusting screw, a connecting plate is fixedly installed on the movable nut, a scraper is connected to the inner side of the connecting plate, and a limit guide rod is connected to the connecting plate.

[0016] The movable nut of the adjusting screw thread connection can be rotated to adjust its position. Together with the connecting plate fixed at the lower end, it can accurately fix the scraper connected to the inner side of the connecting plate. The limiting guide rod connected to the connecting plate further reinforces the scraper, ensuring that the scraper is stable in position during operation and avoiding changes in fit due to vibration. This solves the problem of the scraper not being fixed firmly, which affects the scraping effect.

[0017] Furthermore, a sealing component is provided between the pressure plate and the storage container.

[0018] By installing a sealing component between the pressure plate and the storage container, grease can be effectively prevented from leaking out from the gap between the two, thus avoiding grease waste and preventing leaked grease from contaminating the equipment and production environment. The sealing component here is a sealing ring made of rubber.

[0019] The beneficial effects of this application are: 1. The combination of the annular first oil passage and the secondary oil passage composed of multiple arc-shaped grooves enables the lubricating grease to be evenly distributed, solving the problem of insufficient local lubrication, reducing bearing wear, and extending service life. 2. The adjusting screw on the support frame can adjust the fit between the scraper and the press roller, thereby effectively improving the scraping effect, while the collection trough installed at the lower end can collect impurities in a concentrated manner to avoid scattering and contamination. 3. The linear actuator that works with the storage container has a movable pressure plate to actively push the grease, solving the problem of untimely oil supply caused by reliance on gravity.

Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0024] The press roller provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0025] Example 1: like Figures 1 to 5 As shown, an embodiment of this application provides a press roller, including: The frame 100 has bearing seats 110 at both ends of its upper part for rotatably supporting the press rolls, and an oil injection channel 120 is provided on the outside of the bearing seat 110. The first oil passage 200 is arranged in a ring within the bearing housing 110, and its left and right sides are respectively connected to the first auxiliary oil passage 210 and the second auxiliary oil passage 220. A support frame 300 is provided on both sides of the press roller. A collection groove 310 is provided at the lower end of one side of the support frame 300. A connecting arm 320 is installed on one side of the support frame 300. A fixed seat 330 is installed at the upper end of the side of the connecting arm 320 away from the support frame 300. An adjusting screw 340 is connected to the fixed seat 330. A scraper 350 is movably connected to one side of the adjusting screw 340. The first auxiliary oil passage 210 and the second auxiliary oil passage 220 are each composed of multiple arc-shaped grooves connected end to end. The corresponding arc-shaped grooves are connected to the first oil passage 200, and an oil injection device 400 is connected to the oil injection channel 120.

[0026] In some embodiments of this application, such as Figure 1 As shown, the press roller described above uses a frame 100 as the overall support base. The bearing seats 110 at both ends of the upper part of the frame 100 can provide rotatable support for the press roller, ensuring that the press roller can rotate stably during operation. The oil injection channel 120 on the outside of the bearing seat 110 can provide an entry path for lubricating grease. It works in conjunction with the first oil passage 200 installed in an annular shape inside, and the first secondary oil passage 210 and the second secondary oil passage 220 connected to the first oil passage 200. The two secondary oil passages are composed of multiple arc-shaped grooves connected end to end. The connection of the arc-shaped grooves is connected to the first oil passage 200, so that the lubricating grease can be evenly distributed in the bearing seat 110 through the cooperation of the main and secondary oil passages. This solves the problem of uneven distribution of lubricating grease in the press roller bearing chamber and insufficient local lubrication leading to accelerated bearing wear, thereby effectively extending the service life of the bearing.

[0027] Meanwhile, the support frames 300 on both sides of the press roller provide a stable mounting base for the scraping and collecting components. The collection groove 310 at the lower end of one side can collect the scraped impurities in a concentrated manner, preventing impurities from scattering and polluting the production environment, thus improving the problem of impurity scattering caused by the unreasonable design of the existing collection structure. In addition, the connecting arm 320 on one side of the support frame 300 is connected to the fixing plate. The adjusting screw 340 on the fixing plate can flexibly adjust the position of the scraper 350 connected at the lower end, so that the scraper 350 can maintain a suitable fit with the surface of the press roller according to actual needs, improving the scraping effect and solving the problems of inaccurate position adjustment and unstable scraping effect of the existing scraping components.

[0028] Furthermore, the oil injection channel 120 is connected to the first oil channel 200.

[0029] In this application, the oil injection channel 120 is connected to the first oil passage 200, which can ensure that the lubricating grease can directly enter the first oil passage 200, reduce the loss on the grease delivery path, improve the grease utilization rate, and avoid the problem of low lubrication efficiency caused by the unreasonable existing oil injection path.

[0030] Example 2: This application provides a press roller, which, in addition to the above-mentioned technical features, also includes the following technical features.

[0031] like Figures 1 to 4 as well as Figure 6 As shown, the oil injection device 400 includes: Storage container 410 is used to store grease, and has an oil outlet 411 at its lower part; A sealing end cap 420 is disposed on the upper part of the storage container 410, and a linear actuator 430 is disposed on the sealing end cap 420; The telescopic rod of the linear actuator 430 passes through the sealed end cap 420 and extends into the storage container 410, where a pressure plate 440 is connected at the end.

[0032] In this embodiment, the oiling device 400 includes a storage container 410 for storing lubricating grease to ensure a continuous grease supply; a sealing end cap 420 effectively seals the storage container 410 to prevent external impurities from entering and contaminating the grease; and a linear actuator 430 drives a pressure plate 440 to move within the storage container 410 via a telescopic rod, thereby actively pushing the grease. This solves the problem of untimely oil supply caused by the existing oiling device 400 relying on gravity for oil supply, ensuring that the grease can be stably delivered to the oiling channel 120. The linear actuator 430 can be an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder.

[0033] Furthermore, the storage container 410 is provided with an outlet 412 at the bottom, and the inner diameter of the storage container 410 gradually decreases from the outlet 412.

[0034] The outlet 412 installed at the bottom of the storage container 410 has an inner diameter that gradually decreases towards the outlet 412, which can guide grease to accumulate at the outlet, reduce grease residue in the container, improve grease utilization, and avoid waste caused by grease that is difficult to drain from the bottom of the container.

[0035] Example 3: This application provides a press roller, which, in addition to the above-mentioned technical features, also includes the following technical features.

[0036] like Figures 1 to 3 As shown, a movable nut 500 is threadedly connected to one side of the adjusting screw 340. A connecting plate 510 is fixedly installed at the lower end of the movable nut 500. A scraper 350 is connected to the inner side of the connecting plate 510, and a limit guide rod 520 is connected to the upper part of the connecting plate 510.

[0037] In this embodiment, the movable nut 500 threaded on one side of the adjusting screw 340 can be rotated to adjust its position. Together with the connecting plate 510 fixed at the lower end, it can accurately fix the scraper 350 connected to the inner side of the connecting plate 510. The limiting guide rod 520 on the connecting plate 510 further reinforces the scraper 350, ensuring that the position of the scraper 350 is stable during operation and avoiding changes in the fit due to vibration. This solves the problem that the scraper 350 is not firmly fixed and affects the scraping effect.

[0038] Example 4: This application provides a press roller, which, in addition to the above-mentioned technical features, also includes the following technical features.

[0039] like Figure 6 As shown, a sealing component 600 is provided between the pressure plate 440 and the storage container 410.

[0040] In this embodiment of the application, by installing a sealing component 600 between the pressure plate 440 and the storage container 410, grease can be effectively prevented from leaking from the gap between the two, which not only avoids grease waste, but also prevents leaked grease from contaminating the equipment and production environment. The sealing component 600 here is a sealing ring made of rubber.
