The automatic screw locking machine uses various electric and pneumatic components to realize the automatic conveying, tightening, and detection of screws. The equipment simplifies the screw tightening process to reduce the number of labor and reduce the adverse factors caused by human error. It is a typical non-standard automation equipment.

[0003] The screws need to be cleaned before being installed by the screw locking machine. In particular, during the production, transportation and storage of the screws, oil, impurities and other pollutants are often attached. These pollutants not only affect the appearance quality of the screws, but also may affect the performance of the screws. After searching, the Chinese patent application number is: CN201910996667.4, which discloses a cleaning and water-throwing integrated device for screw production, including a main base plate, a cleaning mechanism, a rotating mechanism, a carrier plate, a lifting mechanism and a storage mechanism. Two identical specifications are arranged above the main base plate and are symmetrically distributed about the longitudinal center line of the upper end surface of the main base plate. A cleaning mechanism, a rotating mechanism is fixedly installed at the center position of the upper end surface of the main substrate. The invention relates to an integrated cleaning and water-throwing device for screw production. The integrated cleaning and water-throwing device for screw production combines the traditional cleaning and water-throwing steps into one, sprays water on the storage mechanism with screws through a high-pressure nozzle, drives several storage mechanisms to rotate through a rotating mechanism, and raises the height of the storage mechanism through two lifting mechanisms, thereby ensuring that the screws inside the storage mechanism can be cleaned in all directions, and finally closes the cleaning mechanism, and continues to drive the screws to rotate centrifugally through the rotating mechanism to perform water-throwing operations, thereby improving the working efficiency of cleaning and water-throwing.

[0004] The above technical solution is to simply rinse the screws with water, but this method cannot clean the screws thoroughly, resulting in a lot of unnecessary waste of water resources and reduced cleaning efficiency. Therefore, we need to propose a screw cleaning mechanism for a screw locking machine. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figures 1-3 , the present utility model provides a technical solution:

[0029] A screw cleaning mechanism for a screw locking machine, comprising:

[0030] A main body structure; the main body structure includes a base 1 and a cleaning pool 2. The cleaning pool 2 is arranged on the base 1, and a top plate 3 driven by a cylinder 20 to lift and lower is arranged directly above the base 1; both outer walls on both sides of the cleaning pool 2 are symmetrically installed with cylinders 20. The upper ends of the piston rods of the four groups of cylinders 20 are fixedly connected to the bottom of the top plate 3, and the four groups of cylinders 20 are synchronously arranged to drive the top plate 3 to lift and lower.

[0031] A cleaning mechanism arranged at the bottom of the top plate 3; the cleaning mechanism includes a regular hexagon-shaped drum 4. The six outer walls of the drum 4 are all designed to be hollow. The drum 4 is rotatably installed directly below the top plate 3 and is opposite to the opening of the cleaning pool 2. One end of the opening of the drum 4 is clamped with an end cover 5. The drum 4 is driven by a motor 8 to rotate;

[0032] A first connecting arm 6 and a second connecting arm 7 are respectively welded on both sides of the bottom of the top plate 3. The drum 4 is rotatably installed between the lower ends of the first connecting arm 6 and the second connecting arm 7. Specifically, the closed end surface of the drum 4 is rotatably installed at the lower end of the first connecting arm 6 through a shaft rod, and the end cover 5 of the drum 4 is rotatably installed at the lower end of the second connecting arm 7 through a shaft rod.

[0033] The motor 8 is fixedly installed on the top of the top plate 3. The output end of the motor 8 is fixedly connected with a driving wheel 9. The end of the shaft rod on the closed end surface of the drum 4 is provided with a driven wheel 12. The driving wheel 9 is connected to the driven wheel 12 through a belt 10, and a notch 11 for the belt 10 to pass through is opened on the top plate 3.

[0034] In actual use, a drain pipe 13 for discharging sewage is provided at the lower end of one side wall of the cleaning tank 2. Before cleaning, water and a cleaning agent are injected into the cleaning tank 2. After opening the end cover 5 and placing the screws to be cleaned inside the drum 4, the end cover 5 is closed. The cylinder 20 is started to lower the drum 4 until it is submerged in the cleaning tank 2. The motor 8 is started to transmit power to the drum 4 through the belt 10, thereby driving the drum 4 to turn in the cleaning tank 2. In this process, on the one hand, the water and the cleaning agent in the cleaning tank 2 can be fully mixed to achieve a good cleaning effect. On the other hand, a certain frictional force can be generated between the water and the screws, and between the screws and the screws, so as to better remove the impurities and oil stains attached to the screws. After a period of time, the motor 8 is turned off, and the top plate 3 is reset by the cylinder 20. The impurities and oil stains flow into the cleaning tank 2 through the leakage holes on the outer wall of the drum 4. Then, the end cover 5 is opened to take out the clean screws.

[0035] Generally speaking, the structure of this device is simple and easy to use. Through the setting of the cleaning mechanism, when cleaning the screws, it can be continuously turned over. It can not only increase the friction between the screws and the cleaning liquid to improve the cleaning ability, but also enable the screws to rub against each other to improve the cleaning efficiency. It can well remove the oil stains and impurities attached to the screws, and will not cause too much waste of water resources, having a high practical value.

[0036] It is worth mentioning that please refer to Figure 3 :

[0037] The second connecting arm 7 includes an upper arm 701 and a lower arm 702. The upper arm 701 and the lower arm 702 are hinged together, and the upper arm 701 and the lower arm 702 are positioned by a pin rod. The end cover 5 of the drum 4 is rotatably installed at the lower end of the lower arm 702. Positioning seats 14 for positioning the upper arm 701 and the lower arm 702 are provided on the outer walls of one side of the upper arm 701 and the lower arm 702. Positioning holes 15 for inserting the pin rod are opened on the positioning seats 14.

[0038] By rotatably installing the drum 4 at the lower ends of the first connecting arm 6 and the second connecting arm 7, the second connecting arm 7 includes an upper arm 701 and a lower arm 702, and the end cover 5 is rotatably installed at the lower end of the lower arm 702. The upper and lower arms 702 are positioned by a pin rod. When the drum 4 rotates, the pin rod is inserted into the positioning hole 15 on the positioning seat 14 on the upper and lower arms 702 to fix the end cover 5. Under the condition of ensuring the rotation ability, the end cover 5 is firmly clamped at the open end of the drum 4. After the cleaning is completed, the pin rod is taken out. Since the upper and lower arms 702 are hinged together, the lower arm 702 can be rotated to separate the end cover 5 from the open end of the drum 4, thus facilitating the putting in and taking out of the screws. The structure is simple and easy to use.

[0039] Please refer to Figure 1 andFigure 4 , in order to improve the supporting ability of the top plate 3 for the drum 4 and enhance the stability and safety during the operation of the equipment, the present application also makes the following design:

[0040] It further includes an auxiliary support mechanism. A regular hexagonal-shaped slot corresponding to the drum 4 is opened on one side of the end cover 5, and the open end of the drum 4 is clamped inside the slot. The auxiliary support mechanism includes an auxiliary wheel 16 arranged outside the drum 4 and two groups of support arms 18 welded to the bottom of the top plate 3. Annular grooves 17 are opened on both side walls of the auxiliary wheel 16, and rollers 19 are rotatably installed at the lower ends of the support arms 18. The outer walls of the two groups of rollers 19 are respectively attached to the inner walls of the two groups of annular grooves 17.

[0041] By providing a circular auxiliary wheel 16 on the outer wall of the drum 4, annular grooves 17 are opened on both outer walls of the auxiliary wheel 16, and two groups of support arms 18 with rollers 19 are symmetrically welded to the bottom of the top plate 3. The rollers 19 roll in the annular grooves 17, which can not only ensure the rotation ability of the drum 4 but also play an auxiliary supporting role for the drum 4, improving the stability and safety during the operation of the equipment.
