Description

Technical Field

[0001] This utility model relates to the technical field of bearing cleaning equipment, specifically a bearing cleaning device for a paper rewinding machine. Background Technology

[0002] In the paper roll production process, the paper roll rewinder plays a crucial role, and its internal bearings are one of the key components ensuring the normal and stable operation of the rewinder. After prolonged use, bearings accumulate a large amount of dust, oil, and other impurities. These contaminants not only affect the lubrication performance of the bearings but may also lead to accelerated wear, decreased operating accuracy, and other problems, thereby affecting the overall working efficiency and product quality of the paper roll rewinder.

[0003] Traditional bearing cleaning methods are often simple and crude, involving manual wiping or simple soaking. These methods have many shortcomings. Manual wiping is difficult to thoroughly clean all the complex parts of the bearing, and it is easy to miss some hidden corners. Moreover, the work efficiency is low and it is not suitable for cleaning batches of bearings. While simple soaking can remove oil and other impurities to a certain extent, it has limited effectiveness in cleaning some stubborn stains, and the subsequent drying process is also quite cumbersome. Utility Model Content

[0004] In view of the above-mentioned background technology, there are shortcomings and defects in the working efficiency of the existing technology.

[0005] The present invention discloses a bearing cleaning device for a paper rewinding machine, comprising a housing, a pushing component disposed on one side inside the housing, and two fixing plates disposed on the other side inside the housing. A driving component is disposed between one of the fixing plates and the housing. The two fixing plates are fixedly connected by a connecting rod. Multiple extension plates are disposed around the outer ring of the fixing plates. Grooves are disposed on the extension plates. An adjusting component is disposed between the extension plates and the fixing plates. A cleaning component is disposed above the fixing plates.

[0006] Furthermore, multiple expansion plates are evenly distributed, with at least two expansion plates provided. Each expansion plate has a rubber pad on its surface. One of the fixed plates has a sliding groove one, and the other fixed plate has a sliding groove two. The two ends of the expansion plate are slidably disposed with the sliding groove one and the sliding groove two, respectively.

[0007] Furthermore, the adjusting assembly includes a screw, with both ends of the screw rotatably mounted on the corresponding fixed plates. A tapered plate is provided on the screw, and the tapered plate is threadedly connected to the screw. The tapered plate is slidably disposed with the connecting rod. The side of the extension plate closest to the tapered plate is inclined, and the tapered plate is slidably disposed with the extension plate.

[0008] Furthermore, multiple conical plates are provided, with at least one conical plate provided, and the multiple conical plates are fixedly connected to each other by a connecting rod.

[0009] Furthermore, the pushing component includes a sleeve with an inner diameter larger than the maximum expansion diameter of the expansion plate, and an electric telescopic rod is provided between the sleeve and the outer shell, with one end of the electric telescopic rod threadedly connected to the sleeve.

[0010] Furthermore, the cleaning component includes multiple nozzles, with a diverter between the multiple nozzles and the diverter connected to an external cleaning tank.

[0011] Furthermore, the drive assembly includes a rotating shaft, one end of which is mounted on the fixed plate, and the other end of which is provided with a drive source. Both the drive source and the electric telescopic rod are provided with support plates below them, and the support plates are mounted on the outer casing.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting an extension plate and its grooves, and cooperating with a pushing component to move the bearing on the extension plate, allows the grooves to be loaded on different areas of the bearing's inner wall. This allows the cleaning fluid to clean the designated areas of the bearing through the grooves, ensuring a complete and thorough cleaning. Compared with traditional manual wiping, which is difficult to thoroughly clean the complex parts of the bearing, easily misses hidden corners, and simple soaking cleaning has limited effectiveness in cleaning stubborn stains, this device can effectively solve these problems. It can better remove dust, oil, and other impurities adsorbed by the bearing after long-term use, ensure good lubrication performance of the bearing, maintain its operational accuracy, and thus improve the working efficiency and product quality of the entire paper rewinding machine.

[0014] 2. This utility model, through the coordinated structure of drive components, push components, and cleaning components, can realize an automated or semi-automated cleaning process, which can efficiently clean bearings. Compared with the low efficiency of traditional manual wiping, it is more suitable for the cleaning of batch bearings, and helps to complete the bearing cleaning process more quickly in the paper roll production process, ensuring the normal and stable operation of the paper roll rewinding machine and meeting production needs.

[0021] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0022] Please see Figure 1 , Figure 2 The bearing cleaning device for a paper rewinding machine of this utility model includes a housing 1. A pushing component is provided on one side inside the housing 1. The pushing component includes a sleeve 14. The sleeve 14 is made of alloy steel with moderate hardness and the surface is smoothed to reduce the friction when in contact with the bearing and improve the pushing efficiency. The inner diameter of the sleeve 14 is larger than the maximum expansion diameter of the expansion plate 5 to ensure that the sleeve 14 will not collide or rub against the expansion plate 5 when pushing the bearing to move, thus affecting the normal operation of the device.

[0023] In this embodiment, an electric telescopic rod 13 is provided between the sleeve 14 and the outer shell 1. One end of the electric telescopic rod 13 is threadedly connected to the sleeve 14. The threaded connection facilitates installation and disassembly, and makes it convenient for subsequent maintenance or replacement of the electric telescopic rod 13. At the same time, it can ensure the firmness of the connection, so that the electric telescopic rod 13 can stably drive the sleeve 14 to perform corresponding actions during the extension and retraction process. Two fixing plates 3 are provided on the other side of the inner shell 1. A drive assembly is provided between one of the fixing plates 3 and the outer shell 1. The drive assembly includes a rotating shaft 2.

[0024] See Figure 1 , Figure 3As shown, the rotating shaft 2 is made of carbon steel. One end of the rotating shaft 2 is mounted on the fixed plate 3, and the other end of the rotating shaft 2 is equipped with a drive source 15. The drive source 15 is a servo motor with a frequency converter to flexibly adjust the rotation speed according to different bearing cleaning requirements, thereby improving the applicability of cleaning. Support plates 16 are provided below the drive source 15 and the electric telescopic rod 13. The support plates 16 are mounted on the outer shell 1, and the two fixed plates 3 are fixedly connected by a connecting rod 4.

[0025] In this embodiment, the outer ring of the fixed plate 3 is provided with a plurality of extension plates 5, which are evenly distributed. At least two extension plates 5 are provided. The surface of the extension plate 5 is provided with a rubber pad. The rubber pad can increase the friction between the bearing and the bearing, making the bearing more stable when it rotates with the extension plate 5 and moves under the push of the sleeve 14, and less likely to slip off. The rubber pad can also play a certain buffering role, avoiding damage to the bearing and the extension plate 5 due to rigid collision during bearing placement or cleaning.

[0026] See Figure 1 , Figure 3 , Figure 4 As shown, one of the fixed plates 3 is provided with a sliding groove 6, and the other fixed plate 3 is provided with a sliding groove 7. The two ends of the extension plate 5 are slidably disposed with the sliding groove 6 and the sliding groove 7 respectively. The inner walls of the sliding groove 6 and the sliding groove 7 are polished to reduce friction and extend the service life of the sliding parts of the extension plate 5. The extension plate 5 is provided with a groove 8. An adjustment component is provided between the extension plate 5 and the fixed plate 3. The adjustment component includes a screw 9. The two ends of the screw 9 are rotatably mounted on the corresponding fixed plates 3. The screw 9 can be made of wear-resistant alloy steel and the surface is rust-proofed to prevent rust and corrosion caused by contact with cleaning liquids during long-term use, which would affect the adjustment function.

[0027] In this embodiment, a tapered plate 10 is provided on the screw 9. The tapered plate 10 is threadedly connected to the screw 9. The tapered plate 10 is slidably disposed with the connecting rod 4. The side of the extension plate 5 near the tapered plate 10 is inclined. The tapered plate 10 and the extension plate 5 are slidably disposed to ensure smooth sliding between the two and to maintain good fitting accuracy after long-term use. The sliding contact surface can be cleaned and lubricated regularly. Multiple tapered plates 10 are provided, and at least one tapered plate 10 is provided.

[0028] In this embodiment, multiple conical plates 10 are fixedly connected by connecting rod 2 11. When the screw 9 is rotated, all conical plates 10 can move synchronously to ensure the consistency of adjustment of each expansion plate 5. A cleaning component is provided above the fixed plate 3. The cleaning component includes a nozzle 12. Multiple nozzles 12 are provided. A flow divider is provided between multiple nozzles 12. The nozzle 12 adopts a rotatable nozzle and a flow regulating valve design so as to be flexibly adjusted according to the specific condition of the bearing and the cleaning requirements. The flow divider is connected to an external cleaning tank.

[0029] The implementation principle is as follows: First, based on the size of the bearing to be cleaned, the screw 9 in the assembly is rotated to drive the tapered plate 10 to move, so that the extension plate 5 is adjusted to a suitable extension state, so that it can fit the outer diameter of the bearing and place the bearing on the extension plate 5.

[0030] The external cleaning tank in the cleaning assembly delivers cleaning fluid to the nozzle 12 through a distributor. The nozzle 12 begins to spray cleaning fluid. Then, the drive source 15 in the drive assembly starts, driving the rotating shaft 2 to rotate, which in turn causes the fixed plate 3 and its extension plate 5 and other components to rotate together, achieving initial multi-angle rinsing of the bearing. At the same time, the electric telescopic rod 13 in the push assembly starts to work, pushing the sleeve 14, which in turn pushes the bearing to move on the extension plate 5. Since the extension plate 5 is provided with grooves 8, during the movement of the bearing, the grooves 8 can be loaded on different areas of the bearing's inner wall, allowing the cleaning fluid to clean the designated areas of the bearing with the help of the grooves 8, ensuring complete and thorough cleaning, and fully removing dust, oil and other impurities from various parts of the bearing's inner wall.

[0031] After the above-mentioned multi-angle rinsing and targeted cleaning with the help of groove 8, the bearing cleaning work is basically completed. Turn off the drive source 15, electric telescopic rod 13 and the delivery of cleaning fluid, take out the cleaned bearing, and complete the entire bearing cleaning process.

[0032] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
