[0002] In mechanical transmission systems, linear motion modules have a wide range of applications. In the linear motion modules of mechanical transmission systems, precision motion components need to be protected to prevent corrosion and wear caused by dust and debris.

[0003] According to a positive pressure air blowing protection device for a linear motion module disclosed on the patent website (authorization announcement number: CN207188425U), "a positive pressure air blowing protection device for a linear motion module, comprising a module base plate, an air inlet on one side of the module base plate, an air outlet on the other side, an air channel connected between the air inlet and the air outlet, a circuit interface on the air inlet, an exhaust hole connected to the air channel, the exhaust hole and the air channel are connected through the exhaust channel, and a pressure gauge for detecting air pressure is provided at the connection between the air inlet and the air channel. The utility model has the following advantages: when the linear motion module is used in an environment such as dust and fiber, a positive pressure space is formed to prevent tiny dust and fiber from entering the compact components of the linear motion module, thereby avoiding corrosion and wear of precision components."

[0004] In view of the above description, the applicant believes that the following problems exist:

[0005] During use, this utility model can prevent tiny dust and fibers from entering the tight components of the linear motion module by forming a positive pressure space, thereby avoiding corrosion and wear of precision components.

[0029] The adjustable cleaning mechanism 4 includes a first cleaning component 41 and a second cleaning component 42 . The first cleaning component 41 is arranged outside the second cleaning component 42 .

[0030] Furthermore, the first cleaning component 41 includes a first connecting frame 411 and a second connecting frame 412. The first connecting frame 411 and the second connecting frame 412 are fixedly installed on the outside of the connecting plate 2. A driving motor 413 is fixedly installed on the outside of the first connecting frame 411, and a threaded rod 414 is fixedly installed on the output shaft of the driving motor 413. A limiting rod 415 is fixedly installed inside the second connecting frame 412, and a movable push plate 416 is threadedly installed on the outside of the threaded rod 414. A partition 417 is fixedly installed inside the first connecting frame 411 and the second connecting frame 412 to facilitate cleaning of dust and other impurities on the top of the connecting plate 2.

[0031] Furthermore, through grooves are opened at corresponding positions of the movable push plate 416, the limiting rod 415 and the partition 417, and the limiting rod 415 and the partition 417 pass through the through grooves. The bottom of the movable push plate 416 contacts the top of the connecting plate 2, thereby preventing the movable push plate 416 from rotating and ensuring the dust cleaning effect on the top of the connecting plate 2.

[0032] Furthermore, the second cleaning component 42 includes a mounting frame 421, which is fixedly mounted on the outside of the movable push plate 416, a movable frame 422 is slidably mounted inside the mounting frame 421, a first spring 423 is provided inside the mounting frame 421, a first motor 424 is fixedly mounted on the outside of the movable frame 422, and a cleaning roller 425 is fixedly mounted on the output shaft of the first motor 424 to facilitate further cleaning of the top of the connecting plate 2.

[0033] Furthermore, the first spring 423 is arranged between the movable frame 422 and the installation frame 421, and a limiting slide groove is opened inside the installation frame 421 at a position corresponding to the movable frame 422, so that the cleaning roller 425 contacts the top of the connecting plate 2, so that the cleaning roller 425 can always contact the top of the connecting plate 2 to ensure the cleaning effect. Example

[0034] See also Figure 5-6 , and combined with Example 1, it is further obtained that the positive pressure blowing protection mechanism 3 includes a mounting frame 31, the mounting frame 31 is fixedly installed on the outside of the linear motion module body 1, a mounting shell 32 is fixedly installed inside the mounting frame 31, an air outlet pipe 33 is fixedly installed at the bottom of the mounting shell 32, an exhaust hole 34 is opened on the outside of the linear motion module body 1, a filter plate 35 is fixedly installed on the top of the mounting shell 32, a mounting plate 36 is fixedly installed inside the mounting shell 32, a fan 37 is provided at the bottom of the mounting plate 36, a connecting rod 38 is provided on the top of the fan 37, and a scraper 39 is fixedly installed on the top of the connecting rod 38 to prevent external dust from adhering to the surface of the filter plate 35 as the fan 37 runs, causing the positive pressure blowing effect to be reduced.

[0035] Furthermore, connecting holes are opened at corresponding positions of the filter plate 35 and the connecting rod 38, and the connecting rod 38 passes through the connecting holes. The bottom of the scraper 39 contacts the top of the filter plate 35, which is convenient for effectively scraping off the accumulated dust.

[0036] During actual operation, when this device is used, in order to prevent more dust from entering the interior of the linear motion module body 1, the fan 37 can be turned on to generate wind force. At the same time, under the operation of the fan 37, the connecting rod 38 will rotate synchronously, so that the scraper 39 can rotate synchronously to scrape the dust accumulated on the surface of the filter plate 35, and prevent it from entering the interior of the linear motion module body 1 with the action of the air outlet pipe 33 and the exhaust hole 34. At the same time, under the action of the air outlet pipe 33 and the exhaust hole 34, positive pressure blowing can be generated to blow away impurities such as dust, and prevent them from entering the interior of the linear motion module body 1. After blowing, the dust and other impurities will adhere to the surface of the connecting plate 2 To avoid the risk of secondary contamination, the driving motor 413 can be turned on to rotate the threaded rod 414. Under the action of the limit rod 415 and the partition 417, the movable push plate 416 can be moved outside the threaded rod 414, so that the dust on the surface of the connecting plate 2 can be pushed to avoid secondary contamination. At the same time, the first motor 424 can be turned on to rotate the cleaning roller 425 to further clean the surface of the cleaned connecting plate 2. Under the action of the first spring 423, the cleaning roller 425 can be ensured to always be in contact with the surface of the connecting plate 2 to ensure the cleaning effect. By rotating the first motor 424 forward and reversely, the reciprocating cleaning of the surface of the connecting plate 2 can be achieved.
