Description

Technical Field

[0001] This utility model belongs to the field of bearing cleaning equipment, and in particular relates to a cleaning device for textile machinery bearings. Background Technology

[0002] Bearings are common supporting parts for rotating components in mechanical equipment. In existing textile machines, bearings are required in the roller section, shedding mechanism, weft insertion mechanism, and near the spindle to reduce rotational friction, maintain stable rotational speed, and ensure transmission accuracy.

[0003] Textile machines generate a large amount of lint and other debris during operation, and bearings typically require grease to reduce the coefficient of friction. Therefore, after prolonged operation, this debris inevitably enters the bearings and mixes with the grease, affecting the smoothness of bearing rotation. To address this issue, those skilled in the art need to periodically disassemble and clean the bearings inside the textile machine. However, common bearing cleaning equipment cannot keep the bearings rotating during the cleaning process, creating cleaning dead zones between the rolling elements and the cage, resulting in poor cleaning effectiveness. Furthermore, the debris accumulated between the rolling elements and the cage is difficult to remove quickly during cleaning, further reducing cleaning efficiency and extending the textile machine's downtime for maintenance.

[0008] Furthermore, the side wall of the splicing connector is provided with a limiting cut surface, and the inner side wall of the splicing hole is provided with a positioning cut surface.

[0015] Compared with the prior art, the cleaning device for textile machinery bearings described in this utility model has the following advantages:

[0016] (1) The cleaning device for textile machinery bearings described in this utility model has a rotatable drive disc inside the cleaning tank, which can position the bearing to be cleaned via a positioning pin, and simultaneously make the outer ring sidewall of the bearing to be cleaned contact the sidewall of the drive disc. During the cleaning process, the operator can drive the drive disc to rotate, thereby using friction to make the outer ring of the bearing to be cleaned start to rotate. Because there is an anti-slip sleeve on the positioning section, the inner ring of the bearing to be cleaned will be limited in rotation, and the bearing to be cleaned will then be in a rotating state. In this state, the rolling elements in the bearing to be cleaned will roll, thus avoiding the formation of cleaning dead corners near the rolling elements and improving the cleaning effect of the bearing. At the same time, the bearing to be cleaned in the rotating state can also facilitate the removal of accumulated debris, thereby improving the cleaning efficiency of the bearing.

[0017] (2) The cleaning device for textile machinery bearings described in this utility model has an inlet pipe and an outlet pipe on the base. During use, the operator can connect the inlet pipe and outlet pipe to the outlet and inlet sections of a circulating pump, respectively, thereby circulating the cleaning fluid inside the device and enhancing the cleaning efficiency of the bearings. Simultaneously, the device has a filter screen inside the filter tank, which intercepts debris that falls off during the cleaning fluid circulation, ensuring a good bearing cleaning effect.

[0031] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] A cleaning device for textile machinery bearings, the structure of which can be made of Figures 1-7 The following is an illustration. In this embodiment, the cleaning device for textile machinery bearings includes: a base 1, a support frame, and a drive disc 3. The base 1 provides operating space for the cleaning work, the support frame supports the drive disc 3 and facilitates the positioning of the bearing 7 to be cleaned, and the drive disc 3 drives the bearing 7 to be cleaned to rotate during the cleaning process, thereby improving the cleaning effect and cleaning efficiency.

[0033] Specifically, a cleaning groove 11 is provided on the top surface of the base 1, and a support frame is detachably installed inside the cleaning groove 11. Figure 5 As shown, the support frame includes a support plate 21, a support ring 22, and multiple support rods 23. The support plate 21 is disposed inside the support ring 22, and the multiple support rods 23 are arranged radially around the support plate 21. The support plate 21 is connected to the support ring 22 through the support rods 23.

[0034] To enable the detachable connection of the support frame, this embodiment may provide a limiting ring 18 with an inner diameter equal to that of the support ring 22 on the inner wall of the cleaning tank 11, so as to support the support frame through the limiting ring 18. Simultaneously, a positioning protrusion 221 may be provided on the bottom surface of the support ring 22, and a positioning groove 181 for accommodating the positioning protrusion 221 may be provided on the top surface of the limiting ring 18. When the support frame is installed inside the cleaning tank 11, the positioning protrusion 221 will insert into the positioning groove 181, thereby limiting the rotation of the support frame through the cooperation of the positioning protrusion 221 and the positioning groove 181, preventing abnormal rotation of the support frame during use.

[0035] To drive the bearing 7 to be cleaned to rotate and to ensure proper positioning of the bearing 7 to be cleaned, such as... Figure 2 and Figure 3 As shown, in this embodiment, the drive disk 3 is rotatably mounted on the support disk 21, and a detachable positioning post is provided on the support rod 23. Before cleaning, the operator can place the bearing 7 to be cleaned onto the positioning post (the sealing ring and dust cover at the end of the bearing 7 to be cleaned need to be removed beforehand) to fix the position of the bearing 7 to be cleaned and to make the outer ring sidewall of the bearing 7 to be cleaned contact the sidewall of the drive disk 3. During cleaning, the operator can drive the drive disk 3 to rotate, thereby driving the outer ring of the bearing 7 to be cleaned to move, so that the bearing 7 to be cleaned is in a rotating state, thereby improving the cleaning effect and cleaning efficiency.

[0036] Optionally, to achieve a rotatable connection between the drive disk 3 and the support disk 21, the support disk 21 may be provided with a mounting hole 211, and a connecting shaft 32 may be provided on the bottom surface of the drive disk 3. During assembly, the operator can insert the connecting shaft 32 into the mounting hole 211, and a bearing should be provided between the connecting shaft 32 and the mounting hole 211 to ensure smooth rotation of the drive disk 3 during use.

[0037] As an optional implementation of this embodiment, to reduce the difficulty of rotating the drive disc 3, the cleaning device for textile machinery bearings may also include a drive assembly. For example... Figure 6 As shown, the drive assembly includes a sealing cover 5 and a drive motor 6, with the drive motor 6 mounted on the sealing cover 5, which also has a channel hole. During assembly, the sealing cover 5 is detachably mounted on the top of the cleaning tank 11, and the output shaft of the drive motor 6 is inserted into the cleaning tank 11 along the channel hole. Simultaneously, the bottom end of the output shaft of the drive motor 6 should also have a connector 61, and a connector hole 31 for accommodating the connector 61 is provided on the top surface of the drive disk 3. After the drive assembly and base 1 are assembled, the connector 61 is inserted into the connector hole 31, so that the torque output by the drive motor 6 is transmitted into the drive disk 3, thereby driving the drive disk 3 to rotate.

[0038] It should be noted that, to ensure reliable transmission between the drive assembly and the drive disk 3, a limiting cut surface may be provided on the side wall of the connector 61, and a positioning cut surface may be provided on the inner side wall of the connector hole 31. When the connector 61 is inserted into the connector hole 31, the limiting cut surface will fit against the positioning cut surface, thereby ensuring that the drive disk 3 rotates following the output shaft of the drive motor 6 during operation.

[0039] In addition, to prevent the cleaning fluid inside the cleaning tank 11 from splashing outwards during operation, a sealing flange 51 can be provided on the bottom surface of the sealing cover 5. A sealing ring 511 should be provided on the side wall of the sealing flange 51, and a sealing groove 111 for accommodating the sealing ring 511 should be provided on the inner side wall of the cleaning tank 11. After the sealing cover 5 is installed on the base 1, the sealing flange 51 will be inserted into the cleaning tank 11, and the sealing ring 511 will enter the sealing groove 111. The cooperation between the sealing ring 511 and the sealing groove 111 can increase the contact area between the sealing flange 51 and the inner side wall of the cleaning tank 11, so as to achieve a good sealing effect between the sealing cover 5 and the base 1.

[0040] Figure 7The diagram shows a positioning post. In this embodiment, the positioning post includes an operating section 41, a positioning section 42, and a limiting section 43 connected sequentially from top to bottom. The outer diameter of the operating section 41 is smaller than that of the positioning section 42, and the outer diameter of the limiting section 43 is larger than that of the positioning section 42. An anti-slip sleeve 421 with an outer diameter equal to the inner diameter of the inner ring of the bearing 7 to be cleaned is fitted onto the positioning section 42. During use, the operator first inserts the positioning section 42 into the inner ring of the bearing 7 to be cleaned, so that the outer wall of the anti-slip sleeve 421 fits tightly against the inner wall of the inner ring of the bearing 7 to be cleaned. Then, the positioning post is installed on the support rod 23 so that the side wall of the outer ring of the bearing 7 to be cleaned contacts the side wall of the drive disc 3. Because the presence of the anti-slip sleeve 421 increases the frictional resistance between the inner ring of the bearing 7 to be cleaned and the positioning section 42, the inner ring of the bearing 7 to be cleaned will not be able to rotate when the drive disc 3 is started. The outer ring of the bearing 7 to be cleaned will move with the drive disc 3 under the action of friction, so that the bearing 7 to be cleaned will enter the rotating state. This prevents the formation of a cleaning dead corner near the rolling element of the bearing 7 to be cleaned and facilitates the separation of debris accumulated near the rolling element from the bearing 7 to be cleaned during the cleaning process.

[0041] Optionally, to achieve a detachable connection between the positioning post and the support rod 23, a threaded connector 44 can be provided on the bottom surface of the positioning post, and multiple threaded holes 231 arranged along the length of the support rod 23 can be provided on the support rod 23. After the worker places the bearing 7 to be cleaned onto the positioning post, the threaded connector 44 can be screwed into the threaded hole 231 to fix the positioning post on the support frame, thus preventing abnormal movement of the bearing 7 to be cleaned during the cleaning process.

[0042] It should be noted that, since various bearing sizes may need to be cleaned in actual work, operators should select and replace the anti-slip sleeve 421 according to the inner diameter of the inner ring of the bearing 7 to be cleaned before using this device to ensure that the inner ring of the bearing 7 to be cleaned obtains good rotational limitation during the cleaning process. Correspondingly, operators should also select the threaded hole 231 into which the threaded connector 44 is inserted according to the outer diameter of the outer ring of the bearing 7 to be cleaned to ensure good contact between the side wall of the outer ring of the bearing 7 to be cleaned and the side wall of the drive disc 3.

[0043] As another optional implementation of this embodiment, in order to further improve the cleaning efficiency and cleaning effect of this device, this device can also circulate the cleaning fluid inside the cleaning tank 11 during bearing cleaning and filter the cleaning fluid during the circulation process.

[0044] Specifically, to achieve the above functions, this embodiment may also provide a filter tank on the top surface of the base 1, and a removable filter screen 12 inside the filter tank. By setting the filter screen 12, the interior of the filter tank can be divided into a turbid liquid cavity 13 and a clear liquid cavity 14, wherein the turbid liquid cavity 13 is located above the filter screen 12, and the clear liquid cavity 14 is located below the filter screen 12, and the turbid liquid cavity 13 is connected to the cleaning tank 11 through a connecting hole 131. At the same time, an inlet pipe 15 and an outlet pipe 16 may also be provided on the side wall of the base 1, and the inlet pipe 15 is connected to the cleaning tank 11, and the outlet pipe 16 is connected to the clear liquid cavity 14.

[0045] During operation, the operator can connect the inlet pipe 15 and outlet pipe 16 to the outlet and inlet sections of the circulation pump (not shown in the figure), respectively. After starting the circulation pump, the cleaning fluid inside the cleaning tank 11 will first enter the turbid liquid cavity 13 through the connection hole 131, and after being filtered by the filter screen 12, it will enter the clear liquid cavity 14. The filter screen 12 will then intercept any debris that falls off during the cleaning process, preventing it from affecting the subsequent cleaning effect. Subsequently, the filtered cleaning fluid will enter the circulation pump through the outlet pipe 16, and the circulation pump will pump the cleaning fluid back into the cleaning tank 11 through the inlet pipe 15, allowing the cleaning fluid to circulate within the device and improving the bearing cleaning efficiency.

[0046] In addition, to prevent the cleaning fluid from splashing outwards during the circulation process, a removable sealing cap 17 can be provided at the top of the filter tank to seal the top of the filter tank.

[0047] The effects of the above solution are explained below:

[0048] This embodiment provides a cleaning device for textile machinery bearings. It can position the bearing to be cleaned using a positioning pin and rotate the bearing by driving a drive disc, thereby improving the cleaning efficiency and effect. Furthermore, this device can circulate the cleaning fluid during the cleaning process and filter the circulating cleaning fluid, further enhancing the cleaning effect on the bearings.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
