DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Example

[0030] like Figures 1 to 8 As shown, an embodiment of the present invention provides a surface cleaning device for an automobile face mask grille injection molded part, comprising a cleaning chamber 1 and a support shell 6, wherein the cleaning chamber 1 is fixedly connected to the inner cavity of the support shell 6, a cleaning mechanism 2 is arranged above the inner cavity of the cleaning chamber 1, a sewage discharge mechanism 3 is arranged at the bottom of the cleaning chamber 1, and a cylinder 5 is fixedly connected to the inner cavity of the support shell 6;

[0031] The cleaning mechanism 2 includes a filter plate 21, which is fixedly connected to the output end of the cylinder 5, and the filter plate 21 is fitted with the inner wall of the cleaning bin 1. A middle plate 22 is fixedly connected to the middle of the filter plate 21, and a water pipe 23 is fixedly connected to the middle of the middle plate 22. A spring assembly 24 is fixedly connected to the top of the inner cavity of the water pipe 23, and a water blocking plate 25 is fixedly connected to the bottom of the spring assembly 24. A pulling assembly 26 is fixedly connected to the bottom of the water blocking plate 25. A dirty water bin 28 is fixedly connected to the bottom of the cleaning bin 1. The inner cavities of the cleaning bin 1 and the dirty water bin 28 are connected, and a damping ring 27 is fixedly connected to the inner cavity of the dirty water bin 28. The pulling assembly 26 is movably sleeved in the inner cavity of the damping ring 27. A blocking plate 291 is fixedly connected to the bottom end of the filter plate 21, and a blocking plate 292 is fixedly connected to the top of the dirty water bin 28.

[0032] An ultrasonic transducer 4 is fixedly connected to a side of the cleaning chamber 1 away from the cylinder 5;

[0033] There are multiple blocking plates 1 291 and blocking plates 292, and the middle plate 22 and multiple blocking plates 1 291 are located above the gaps between the multiple blocking plates 292;

[0034] The spring assembly 24 is composed of a damping telescopic rod 241 and a spring 242. The damping telescopic rod 241 is located at the center of the inner cavity of the spring 242. The top ends of the damping telescopic rod 241 and the spring 242 are fixedly connected to the water pipe 23. The bottom ends of the damping telescopic rod 241 and the spring 242 are fixedly connected to the water blocking plate 25. The water blocking plate 25 is fitted with the bottom end of the water pipe 23.

[0035] The pulling assembly 26 is composed of a smooth rod 261 and a threaded rod 262. The smooth rod 261 is fixedly connected to the top of the threaded rod 262. The top of the smooth rod 261 is fixedly connected to the bottom of the water blocking plate 25. The threaded rod 262 is movably sleeved in the inner cavity of the damping ring 27.

[0036] In this embodiment, firstly, an external ultrasonic generator is connected to the ultrasonic transducer 4, and the inner cavity of the cleaning chamber 1 is filled with a cleaning liquid;

[0037] Next, the plastic part is placed on the top of the filter plate 21, and then the cylinder 5 is started to drive the filter plate 21 to descend to press the cleaning liquid, so that the plastic part on the top of the filter plate 21 descends and contacts the cleaning liquid in the inner cavity of the cleaning chamber 1. At this time, the ultrasonic transducer 4 generates ultrasonic waves and acts on the cleaning liquid, so as to clean the plastic part;

[0038] When the filter plate 21 is in the process of descending in the inner cavity of the cleaning chamber 1, it presses the cleaning liquid in the inner cavity of the cleaning chamber 1, and the pulling assembly 26 is blocked by the damping ring 27, so that the water blocking plate 25 is in contact with the bottom end of the water pipe 23. At this time, the cleaning liquid cannot pass through the water pipe 23, so it can only pass through the filter plate 21, and after being filtered, it enters the upper part of the filter plate 21 and contacts the plastic part, while the particles and mud in the cleaning liquid are filtered on the lower surface of the filter plate 21;

[0039] As the filter plate 21 continues to descend, the filter plate 21 is located at the bottom of the inner cavity of the cleaning chamber 1. At this time, the blocking plate 1 291 is located above the blocking plate 2 292, the smooth rod 261 is located above the threaded ring 36, and the pressing rod 31 is not in contact with the water blocking plate 2 381. At this time, the filter plate 21 completes filtering of the cleaning liquid in the inner cavity of the cleaning chamber 1, and collects the particles and mud in the inner cavity of the dirty water chamber 28, so that the plastic parts are only in contact with the cleaning liquid filtered by the filter plate 21, and the filtered particles and mud are collected in the inner cavity of the dirty water chamber 28, so that most of the particles and mud will not contact the plastic parts placed therein, so that the cleaning effect of the plastic parts can be ensured without frequently changing the cleaning liquid, which saves water and improves the cleaning efficiency;

[0040] During the cleaning process of the plastic parts, the cylinder 5 drives the filter plate 21 to rise and fall, so that the particles and mud processed around the plastic parts are separated from the plastic parts. After the cleaning is completed, the cylinder 5 drives the filter plate 21 to rise to the top of the inner cavity of the cleaning chamber 1. During the rising process of the filter plate 21, due to the socket connection between the damping ring 27 and the pulling component 26, a large friction force is generated between the pulling component 26 and the damping ring 27, so that the pulling component 26 is subjected to resistance when rising, so that the water blocking plate 25 at the top of the pulling component 26 is separated from the water pipe 23, so that the cleaning liquid just used for cleaning the plastic parts above the filter plate 21 enters the bottom of the filter plate 21 from the water pipe 23, and then the plastic parts at the top of the filter plate 21 can be taken away.

[0041] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 As shown, the sewage discharge mechanism 3 includes a mounting cylinder 33, which is fixedly connected to the bottom of the outer side of the dirty water tank 28, and the inner cavity of the mounting cylinder 33 is fixedly connected to a coil spring 34, and the center of the coil spring 34 is fixedly connected to a rotating rod 35, and a through hole is opened in the middle of the rotating rod 35, and a threaded ring 36 is fixedly connected to the top of the inner cavity of the rotating rod 35, and the bottom end of the threaded rod 262 is meshed with the threaded ring 36, and a stirring blade 37 is fixedly connected to the outer side of the rotating rod 35, and the bottom end of the damping ring 27 is movably connected to the top of the rotating rod 35;

[0042] A circular hole is opened at the center of the bottom of the mounting tube 33, and the through hole of the rotating rod 35 is connected to the outside through the circular hole of the mounting tube 33, and the through hole is located below the pulling component 26;

[0043] The sewage discharge mechanism 3 also includes a sewage discharge pipe 38, which is fixedly connected to the bottom end of the dirty water tank 28. A spring assembly 2 39 is fixedly connected to the top of the inner cavity of the sewage discharge pipe 38, and a water blocking plate 2 381 is fixedly connected to the bottom end of the spring assembly 29. A lower pressure rod 31 is fixedly connected to the bottom end of the middle plate 22. The water blocking plate 2 381 fits the bottom end of the sewage discharge pipe 38, and the lower pressure rod 31 is located above the water blocking plate 2 381.

[0044] The spring assembly 2 39 includes a damping telescopic rod 2 391 and a spring 2 392. The damping telescopic rod 2 391 is located at the center of the inner cavity of the spring 2 392. The top ends of the damping telescopic rod 2 391 and the spring 2 392 are fixedly connected to the top of the inner cavity of the sewage pipe 38. The bottom ends of the damping telescopic rod 2 391 and the spring 2 392 are fixedly connected to the water blocking plate 2 381.

[0045] A funnel tube 32 is fixedly connected to one side of the support shell 6 close to the lower pressure rod 31 . The bottom end of the dirty water tank 28 is an inclined surface. A waterproof breathable valve 281 is fixedly connected to one side of the dirty water tank 28 close to the funnel tube 32 . The funnel tube 32 is located below the sewage pipe 38 .

[0046] In this embodiment, when the filter plate 21 descends in the inner cavity of the cleaning chamber 1, the threaded rod 262 is engaged with the threaded ring 36, driving the rotating rod 35 to rotate, thereby causing the coil spring 34 to contract and accumulate potential energy;

[0047] After cleaning more workpieces, the inner cavity of the dirty water bin 28 accumulates more particles and mud. At this time, when cleaning plastic parts, the cylinder 5 drives the filter plate 21 to move to the bottom of the inner cavity of the clean bin 1. At this time, the blocking plate 1 291 and the middle plate 22 are located in the gap between the blocking plate 292 and fit with the blocking plate 292, thereby separating the inner cavity of the dirty water bin 28 from the inner cavity of the clean bin 1, so that the dirty water bin 28 can be sealed independently;

[0048] At this time, the smooth rod 261 is located at the threaded ring 36, and is separated from the threaded ring 36 by the threaded rod 262, and the two are no longer meshed, so that the threaded ring 36 loses its limit. At this time, the surface of the smooth rod 261 is smooth and does not mesh with the threaded ring 36, so that the coil spring 34 loses its limit, releasing potential energy to drive the stirring blade 37 to rotate, and agitate the particles and mud in the inner cavity of the dirty water tank 28;

[0049] While the particles and mud in the dirty water tank 28 are being stirred, the lower pressure rod 31 presses the water blocking plate 2 381 downward, and the waterproof breathable valve 281 is ventilated with the outside, so that the sewage in the dirty water tank 28 is discharged from the sewage pipe 38 to the inner cavity of the funnel pipe 32, and then discharged to the outside through the funnel pipe 32;

[0050] This prevents the mud from hanging on the wall of the dirty water tank 28, and prevents the sedimentation of particles and mud from causing unsmooth material discharge, thereby improving the stability of material discharge;

[0051] Then the cleaning liquid can be added to the inner cavity of the cleaning chamber 1, and the added amount can be the same as the amount of sewage discharged from the inner cavity of the dirty water chamber 28. There is no need to discharge all the cleaning liquid in the inner cavity of the cleaning chamber 1 and then add the cleaning liquid. Therefore, the process of adding the cleaning liquid will not affect the normal use of the cleaning chamber 1, further improving the cleaning efficiency.

[0052] Working principle and use process: an external ultrasonic generator is connected to the ultrasonic transducer 4, and the inner cavity of the cleaning chamber 1 is filled with cleaning liquid;

[0053] Next, the plastic part is placed on the top of the filter plate 21, and then the cylinder 5 is started to drive the filter plate 21 to descend to press the cleaning liquid, so that the plastic part on the top of the filter plate 21 descends and contacts the cleaning liquid in the inner cavity of the cleaning chamber 1. At this time, the ultrasonic transducer 4 generates ultrasonic waves and acts on the cleaning liquid, so as to clean the plastic part;

[0054] When the filter plate 21 descends, the pulling assembly 26 is in contact with the damping ring 27, so that the pulling assembly 26 encounters resistance during the process of descending, thereby pushing the water blocking plate 1 25 to contact the bottom of the water pipe 23, so that the cleaning liquid in the inner cavity of the cleaning chamber 1 cannot pass through the water pipe 23, and therefore, during the process of the filter plate 21 descending, the cleaning liquid can pass through the filter plate 21 and contact the plastic part, and the particles and mud in the cleaning liquid of the filter plate 21 cannot pass through the filter plate 21 and contact the plastic part (in the initial state, the cleaning liquid has previously cleaned the plastic part, so the cleaning liquid contains particles and mud);

[0055] When the filter plate 21 descends, the threaded rod 262 is engaged with the threaded ring 36, thereby driving the rotating rod 35 to rotate, and the rotating rod 35 rotates to cause the coil spring 34 to contract and store force;

[0056] When the filter plate 21 descends to the bottom of the inner cavity of the cleaning chamber 1, the blocking plate 1 291 is located above the blocking plate 292, the smooth rod 261 is located above the threaded ring 36, and the pressing rod 31 is located above the water blocking plate 2 381 and does not contact the water blocking plate 2 381;

[0057] Moreover, most of the cleaning liquid in the inner cavity of the clean tank 1 passes through the filter plate 21, and the particles and mud are always below the filter plate 21 because they cannot pass through the filter plate 21. Thereafter, most of the particles and mud are pushed into the inner cavity of the dirty water tank 28;

[0058] When the plastic parts above the filter plate 21 are cleaned, the particles on the surface of the plastic parts remain in the cleaning liquid above the filter plate 21;

[0059] At this time, the cylinder 5 is started to drive the plastic part above the filter plate 21 to rise. During the process of the filter plate 21 rising, due to the friction between the damping ring 27 and the pulling component 26, the pulling component 26 encounters resistance when rising, and then the pulling component 26 is pulled downward, so that the pulling component 26 is separated from the middle plate 22, and then the cleaning liquid carrying particles and mud passes through the filter plate 21 from the water pipe 23 and enters the bottom of the filter plate 21. When the filter plate 21 rises to the top of the cleaning chamber 1, the plastic part can be removed;

[0060] After the cleaning liquid in the inner cavity of the cleaning bin 1 has been used for many times, more particles and mud are accumulated in the inner cavity of the dirty water bin 28. When the filter plate 21 descends in the inner cavity of the cleaning bin 1, it descends to the bottom of the inner cavity of the cleaning bin 1. At this time, the plurality of blocking plates 1 291 are located in the gaps between the plurality of blocking plates 292. The cleaning bin 1 and the dirty water bin 28 are separated by the blocking plates 1 291 and 292.

[0061] At this time, the threaded rod 262 is separated from the threaded ring 36, and the smooth rod 261 is located in the inner cavity of the threaded ring 36. After the rotating rod 35 loses the limit of the threaded rod 262, the coil spring 34 releases its elasticity, driving the rotating rod 35 to rotate, and the rotating rod 35 drives the stirring blade 37 to rotate to stir the sewage in the inner cavity of the dirty water tank 28, so that the particles and mud float up;

[0062] At this time, the pressing rod 31 presses the water blocking plate 381 downward to open the waterproof breathable valve 281, so that the sewage in the inner cavity of the dirty water tank 28 is discharged, and then a small amount of cleaning liquid is added to the inner cavity of the clean tank 1.
