[0059] As Figures 8-9 The lubricating assembly 4 includes a lubricating shell 41, a fixed plate 42 and a spraying piece 43, the rear side of the lubricating shell 41 is fixedly connected with the side wall of the sliding mechanism 2, the side of the lubricating shell 41 away from the guide rail strip 1 is fixedly embedded with the fixed plate 42, and the other side of the lubricating shell 41 is spaced apart from the guide groove of the guide rail strip 1, so as to prevent the friction between the lubricating shell 41 and the guide rail strip 1 from increasing the moving resistance of the sliding mechanism 2, the lubricating shell 41 and the fixed plate 42 form a frame body with the opening direction facing the guide rail strip 1, and the frame body is movably clamped on the side surface of the guide rail strip 1, the relatively closed environment formed by the lubricating shell 41 and the fixed plate 42 can provide a relatively stable space environment for the uniform spraying and dispersion of the lubricating liquid, and avoid the influence of other processes on the lubrication of the guide rail strip 1, the bottom end of the lubricating shell 41 is provided with a leakage groove, which is convenient for timely draining the excess lubricating liquid in the lubricating shell 41, the spraying piece 43 is fixedly embedded in the fixed plate 42, the number of inlets of the spraying piece 43 is one, and the number of outlets of the spraying piece 43 is four, the four outlets of the spraying piece 43 are longitudinally arranged, and the four outlets all face the guide groove of the guide rail strip 1, so that the spraying piece 43 can accurately spray the lubricating liquid to the guide groove of the guide rail strip 1, thereby improving the uniformity of the distribution of the lubricating liquid on the guide rail strip 1.

[0060] As Figures 8-14The cleaning assembly 5 comprises a cleaning shell 51, a fixed block 52 and a movable assembly 7, the front side of the lubricating shell 41 is fixedly connected with the rear side of the cleaning shell 51, the rear side of the fixed block 52 is fixedly connected with two fixed blocks 52, the bottom end of the cleaning shell 51 is provided with a leakage groove, so that the impurities cleaned in the cleaning shell 51 can be discharged in time, and two movable assemblies 7 are horizontally arranged in the cleaning shell 51, the movable assembly 7 comprises a cleaning piece 8 and a supporting piece 9, one side of the cleaning piece 8 is movably connected with the guide rail strip 1, and the other side of the cleaning piece 8 is connected with the cleaning shell 51 through the supporting piece 9, the movable assembly 7 composed of the cleaning piece 8 and the supporting piece 9 can effectively clean the guide groove of the guide rail strip 1, so that the impurities adhered to the guide rail strip 1 can be scraped, the cleanliness of the guide rail strip 1 is improved, and the abrasion speed between the guide rail strip 1 and the sliding mechanism 2 is slowed down.

[0061] As Figures 8-10 The rotating assembly 6 comprises rotating rods 61, rotating sheets 62 and pushing blocks 63, the number of the rotating rods 61 is four, and two of the rotating rods 61 are movably connected with the lubricating shell 41, the remaining two rotating rods 61 pass through the lubricating shell 41 and are movably connected with the fixed block 52, a plurality of rotating sheets 62 are fixedly connected with the rotating rod 61 located in the lubricating shell 41, and the height of the outlet of the spraying piece 43 corresponds to that of the rotating sheet 62, so that when the spraying piece 43 sprays the lubricating liquid, the lubricating liquid can impact the rotating sheet 62 to be uniformly dispersed, the uniform distribution effect of the lubricating liquid on the guide rail strip 1 is effectively improved, and the lubricating liquid can also drive the rotating sheet 62 to rotate, so as to drive the rotating rod 61 to rotate, thereby providing power for the working of the pushing block 63, the pushing block 63 is in the shape of a water drop, and the pushing block 63 is fixedly sleeved on the rotating rod 61 corresponding to the position of the movable assembly 7, so that when the pushing block 63 rotates to contact the cleaning piece 8, the cleaning piece 8 can be pushed to be attached to the guide rail strip 1, and when the pushing block 63 rotates to not contact the cleaning piece 8, the cleaning piece 8 can not be attached to the guide rail strip 1 under the pulling force of the supporting spring, two pushing blocks 63 are correspondingly arranged on one rotating rod 61, and the positions of the two pushing blocks 63 are opposite, two pushing blocks 63 are correspondingly arranged on one movable assembly 7, and the positions of the two pushing blocks 63 are the same, so that when the two rotating rods 61 rotate, the two movable assemblies 7 will alternately attach to the guide rail strip 1 under the action of the pushing block 63, so that the cleaning piece 8 can scrape and shake off the impurities, and the continuous cleaning work of the cleaning piece 8 is ensured.

[0063] Example 2, based on Example 1, such as Figures 8-14 The cleaning component 8 includes a cleaning plate 81, a cleaning bladder 82, a cleaning tube 83, and a cleaning ball 84. The upper and lower ends of the cleaning plate 81 are in movable contact with the inner top and bottom ends of the cleaning housing 51, respectively. The shape of the cleaning plate 81 is adapted to the guide groove of the guide rail 1. Therefore, when the cleaning plate 81 moves towards the guide rail 1, it will fit against the guide groove of the guide rail 1 to effectively scrape away impurities on the guide rail 1. When the cleaning plate 81 moves away from the guide rail 1, it will not fit against the guide groove of the guide rail 1. The guide groove fits snugly to reduce friction between the cleaning plate 81 and the guide rail 1, thereby reducing movement resistance. The front and rear sides of the cleaning plate 81 are provided with transverse cavities, and the cleaning plate 81 is fixedly connected to one side wall of the cleaning bladder 82 through these cavities. The front and rear inner walls of the cleaning bladder 82 are connected by transverse springs, and the cleaning bladder 82 is filled with gas. The tension of the transverse springs provides power for contracting the cleaning bladder 82 into the transverse cavities. Several cleaning tubes 83 are fixedly embedded inside the cleaning plate 81. 3. Along the cleaning plate 81, the cleaning tube 83 is T-shaped, and both ends of the cleaning tube 83 are fixedly connected to two cleaning bags 82 respectively. The cleaning plate 81 has a transverse groove facing the guide rail 1 inside, and the cleaning plate 81 is movably connected to the cleaning ball 84 through the transverse groove. One end of the cleaning bag 82 is fixedly connected to the cleaning ball 84. When the cleaning plate 81 is in contact with the guide groove of the guide rail 1, the cleaning ball 84 is pushed into the transverse groove, and the cleaning tube 83 is squeezed, and the air inside is transferred to the cleaning tube 83. The cleaning chamber 82 expands, causing the cleaning plate 81 to scrape away impurities from the guide rail 1. Some impurities accumulate at the connection between the cleaning plate 81 and the guide rail 1, near the cleaning chamber 82. When the cleaning plate 81 is not in contact with the guide groove of the guide rail 1, the cleaning ball 84 can move outward, and the cleaning tube 83 is pulled, causing the cleaning chamber 82 to contract under the tension of the horizontal spring. At this time, the cleaning chamber 82 deforms and effectively shakes off the impurities on the cleaning plate 81, further improving the impurity cleaning effect.

[0064] like Figures 8-14 The support member 9 includes a support shell 91 and a support plate 92. One end of the support shell 91 is fixedly connected to the inner wall of the cleaning shell 51, and the other end of the support shell 91 is movably engaged with one end of the support plate 92. The other end of the support plate 92 is fixedly connected to the side wall of the cleaning plate 81. The support shell 91 and the support plate 92 are connected by a support spring, so that the tension of the support spring can provide power to pull the cleaning member 8 away from the guide rail 1.

[0065] The working principle of the method of using this invention is as follows:

[0066] When the sliding mechanism 2 is working, the sliding mechanism 2 can move back and forth on the guide rail 1, at this time, the two groups of auxiliary mechanisms 3 located in front of and behind the sliding mechanism 2 are in non-working state, that is, the cleaning piece 8 does not adhere to the guide rail 1, so as to prevent the cleaning piece 8 from increasing the moving resistance of the sliding mechanism 2 by rubbing the guide rail 1, and effectively ensure the normal work of the sliding mechanism 2.

[0067] When the sliding mechanism 2 is working, the sliding mechanism 2 can move back and forth on the guide rail 1, at this time, the two groups of auxiliary mechanisms 3 located in front of and behind the sliding mechanism 2 are in non-working state, that is, the cleaning piece 8 does not adhere to the guide rail 1, so as to prevent the cleaning piece 8 from increasing the moving resistance of the sliding mechanism 2 by rubbing the guide rail 1, and effectively ensure the normal work of the sliding mechanism 2.

[0068] When the sliding mechanism 2 is working, the sliding mechanism 2 can move back and forth on the guide rail 1, at this time, the two groups of auxiliary mechanisms 3 located in front of and behind the sliding mechanism 2 are in non-working state, that is, the cleaning piece 8 does not adhere to the guide rail 1, so as to prevent the cleaning piece 8 from increasing the moving resistance of the sliding mechanism 2 by rubbing the guide rail 1, and effectively ensure the normal work of the sliding mechanism 2.

[0069] The above description of disclosed embodiments enables a person skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application.
