DETAILED DESCRIPTION

[0022] The following will be combined with the attached embodiment of the present utility model Figure 1-6 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] As shown in the figure, the hub bolt 4 to be cleaned in this embodiment has a shoulder portion 41 and a hexagonal hole 42.

[0024] A cleaning device for producing bolts 4, comprising a frame 1, wherein a cleaning mechanism 2 is arranged on the frame 1, wherein the cleaning mechanism 2 comprises a conveying chain 21, a feeding assembly 22, a cleaning roller 23 and a nozzle 24, wherein the conveying chain 21 is rotatably arranged on the frame 1 and is transmission-connected to a first motor 25 arranged on the frame 1, wherein a plurality of the feeding assemblies 22 are arranged on the conveying chain 21, wherein the feeding assemblies 22 comprise a feeding seat 221 arranged on the conveying chain 21, wherein the feeding seat 221 is in the shape of a hexagonal column matching an inner hexagonal hole 42, wherein a plurality of the cleaning rollers 23 are rotatably arranged on the frame 1 and are arranged on one side of a moving path of the feeding seat 221 and the cleaning rollers 23 are transmission-connected to a second motor 26 arranged on the frame 1, wherein a plurality of the nozzles 24 are arranged on the frame 1 and are located on one side of a moving path of the feeding seat 221 and wherein a nozzle of the nozzle 24 faces a gap between two adjacent cleaning rollers 23,

[0025] Specifically, two groups of cleaning rollers 23 and nozzles 24 are symmetrically arranged along the moving path of the material placement seat 221 , and the two groups of cleaning rollers 23 located on both sides of the moving path of the material placement seat 221 are respectively connected to two second motors 26 arranged on the frame 1 .

[0026] Specifically, the material placement assembly 22 further includes a connecting seat 222 , which is fixedly connected to the conveying chain 21 and is provided with a ball bearing 223 , and the material placement seat 221 is fixedly connected to the inner ring of the ball bearing 223 .

[0027] In the above embodiment, the bolt 4 to be cleaned is placed on the material placement seat 221, specifically, the material placement seat 221 is inserted into the hexagonal hole 42, the first motor 25 drives the conveying chain 21 to move and drives the bolt 4 placed on the material placement seat 221 to move toward the cleaning mechanism 2, and the bolt 4 moving into the cleaning mechanism 2 will pass between the two groups of cleaning rollers 23 and the nozzle 24, and the bolt 4 will collide with the cleaning roller 23 when passing through the cleaning roller 23. While the bolt 4 moves with the conveying chain 21, the second motor 26 drives the cleaning roller 23 to rotate, and its transmission is realized by the cooperation of the synchronous belt and the synchronous wheel. The rotating cleaning roller 23 scrubs the surface of the moving bolt 4, and at the same time, the nozzle 24 sprays the cleaning liquid on the moving bolt 4 to rinse it, so that the bolt 4 is scrubbed by the cleaning roller and rinsed by the nozzle 24 multiple times in the process of moving with the conveying chain 21, so as to achieve a more thorough cleaning effect and ensure the quality of the bolt 4 leaving the factory, and in the above-mentioned cleaning process of the bolt 4, the two second motors 26 respectively drive the second motors 26 located at The two groups of cleaning rollers 23 on both sides of the moving path of the bolt 4 rotate in the same direction, and the bolt 4 is driven to rotate while the cleaning rollers 23 rotate and contact with the bolt 4 for brushing, so that the peripheral side of the bolt 4 can be fully brushed by the cleaning rollers and rinsed by the nozzles 24, thereby achieving a more thorough cleaning effect, and the material placement seat 221 fixedly connected to the ball bearing 223 and arranged on the connecting seat 222 can rotate smoothly on the connecting seat 222, thereby ensuring the smoothness of the bolt 4 when it is rotated by the cleaning roller. In addition, according to the structure of different types of bolts 4, different material placement seats 221 adapted to the bolt 4 can be replaced to achieve the fixation of different types of bolts 4. For example, a hexagonal groove matching the big head end of the bolt 4 can be opened on the material placement seat 221, and the big head end of the bolt 4 can be inserted into the hexagonal groove to achieve the fixation of the bolt 4, and the loading operation of placing the bolt 4 on the material placement seat 221 and the unloading operation of removing the bolt 4 from the material placement seat 221 can be achieved by the cooperation of the manipulator, which will not be repeated here.

[0028] Preferably, the frame 1 is provided with two support plates 11 respectively located on both sides of the connecting seat 222, and the connecting seat 222 is fixedly connected with two support rods 224 respectively placed on the two support plates 11. When the material placing seat 221 moves with the conveying chain 21, the support rods 224 are placed on the support plates 11 to slide and provide support for the movement of the material placing seat 221, so that the bolts 4 placed on the material placing seat 221 can move more stably after being brushed by the cleaning roller and flushed by the nozzle 24, thereby ensuring the cleaning effect.

[0029] Preferably, the frame 1 is provided with two recovery covers 12 which are respectively located on both sides of the moving path of the material placement seat 221 and cover the cleaning roller 23 and the nozzle 24. A recovery port is opened on the bottom plate of the recovery cover 12. After the recovery cover 12 covers the cleaning roller 23 and the nozzle 24 therein, the cleaning roller brushes the bolt 4 and the nozzle 24 flushes the bolt 4 in the space formed by the two recovery covers 12, thereby preventing the splashing of the cleaning liquid. The excess cleaning liquid sprayed on the bolt 4 falls into the recovery cover 12 and falls out of the recovery cover 12 through the recovery port, thereby realizing the recovery of the excess cleaning liquid, reducing the waste of the cleaning liquid, and improving the economic and environmental benefits of production.

[0030] Preferably, the frame 1 is provided with two limit plates 13, which are respectively located on both sides of the moving path of the material placement seat 221 and below the cleaning roller 23. The upper ends of the limit plates 13 are bent inward to form a limit portion 131. The limit portions 131 on the two limit plates 13 abut against the shoulder portion 41 of the bolt 4, so that the bolt 4 is limited by the limit portion 131 when it is moved and brushed by the cleaning roller 23 and flushed by the nozzle 24, and is stably maintained on the material placement seat 221, preventing the bolt 4 from falling off from the material placement seat 221, thereby ensuring the cleaning effect.

[0031] Furthermore, the frame 1 is provided with a drying mechanism 3 located behind the cleaning mechanism 2, and the drying mechanism 3 includes a drying box 31, a fan 32 and a heating pipe 33. The drying box 31 is arranged on the frame 1 above the moving path of the material placement seat 221, and a feed port 311 and a discharge port 312 are provided in the drying box 31. The feed port 311 and the discharge port 312 are aligned with the moving path of the bolt 4. The fan 32 is arranged on the drying box 31 and is connected to the drying box 31. The heating pipe 33 is arranged in the drying box 31 below the fan 32.

[0032] In the above preferred embodiment, the bolts 4 that have been cleaned after passing through the cleaning mechanism 2 enter the drying box 31 through the feed port 311, and the wind generated by the fan 32 is heated by the heating tube 33 to form hot air that blows toward the bolts 4, thereby drying the cleaned bolts 4 to prevent impurities in the outside world from adhering to the cleaned bolts 4 to cause secondary pollution, while also improving production efficiency.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
