[0038] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0039] like Figure 1-8As shown, the present invention provides a surface treatment device for hardware accessories, the device comprising: a box 1 storing rust removal liquid, a spiral cleaning pipe 2 vertically arranged inside the box 1, a slideway 3, and an infusion pump 5 fixed on the box 1 and used to inject the rust removal liquid inside the cleaning pipe 2 from the top thereof into the inside thereof;

[0040] The surface of the cleaning tube 2 capable of generating vibrations in the horizontal direction is evenly and fixedly provided with liquid spray holes connected to the interior thereof, the inner wall of the cleaning tube 2 is evenly and fixedly provided with a plurality of brushes 6, the top of the cleaning tube 2 is also connected and fixedly provided with a feeding end 8 for feeding hardware accessories into the interior thereof, a slide 3 is obliquely provided inside the box body 1 located between the cleaning tube 2 and the rust removal liquid level, the discharge end of the slide 3 passes through the side wall of the box body 1, and the cleaned hardware accessories can fall onto the slide 3 and slide out along its surface after being discharged from the cleaning tube 2.

[0041] In the above scheme, the output end of the infusion pump 5 is fixed to the top of the cleaning tube 2 through an infusion tube and communicated with the interior thereof, and the input end is fixed to the bottom of the box body 1 through an inlet tube and communicated with the interior thereof.

[0042] When in use, the infusion pump 5 is started to continuously inject rust removal liquid into the inside of the cleaning tube 2 from the top thereof, and hardware accessories are put into the inside of the cleaning tube 2 from the top thereof through the feeding end 8. When the hardware accessories enter the cleaning tube 2, on the one hand, they roll downward along the cleaning tube 2 under the action of their own gravity, and in the process of rolling, they come into contact with the brush 6 on the inner wall of the cleaning tube 2. The brush 6 can scrape off the rust stains on the surface of the hardware accessories, and the rust removal liquid that enters the cleaning tube 2 discharges the brushed off rust stains from the bottom end of the cleaning tube 2 into the box 1; On the other hand, since the cleaning tube 2 can vibrate in the horizontal direction, when the hardware accessories roll down from the top of the cleaning tube 2 through its interior and out from its bottom, the hardware accessories can be shaken left and right during the falling process through vibration so that the hardware accessories can have a stronger contact with the brush 6, which is equivalent to increasing the scraping force of the brush, so that the brush can brush off the rust stains on the surface of the hardware and improve the cleaning effect. In addition, the rust stains adhering to the brush 6 inside can also be shaken off and discharged from the bottom end of the cleaning tube 2 to achieve automatic cleaning of the inner wall of the cleaning tube 2.

[0043] Therefore, by continuously injecting rust removal liquid into the cleaning tube 2 so that the hardware accessories enter from the top of the cleaning tube and roll out from the bottom thereof, on the one hand, the cleaning tube 2 can be vibrated during the rust removal liquid spraying out of the cleaning tube 2, and the self-cleaning of the cleaning tube can be achieved during the vibration process. On the other hand, the hardware accessories can be more fully contacted with the brush 6 on the inner wall of the cleaning tube 2, thereby increasing the brushing force and improving the cleaning effect. The cleaned rust stains can also be automatically discharged. The machine can work continuously without stopping, thereby improving the work efficiency.

[0044] The purpose of the spiral setting of the cleaning tube 2 is to extend the path of the rust removal liquid and the hardware accessories in the cleaning tube 2, so that the hardware accessories can fully contact with the flowing rust removal liquid on the one hand, thereby improving the rust removal effect; on the other hand, the hardware accessories can fully contact with the brush 6 on the inner wall of the cleaning tube 2, so that the rust removal operation on the hardware accessories can be better carried out in all directions, further improving the rust removal effect.

[0045] In addition, the infusion pump 5 is started so that the rust removal liquid in the box body 1 enters the interior of the cleaning tube 2 from the top through the infusion pump 5 and flows back to the box body 1 through the spray holes on the surface of the cleaning tube 2 and its bottom port, and then is input into the cleaning tube 2 by the infusion pump 5 for recycling and reuse, which has the advantages of energy saving and environmental protection and avoids waste of resources.

[0046] In a preferred embodiment of the present invention, a baffle is vertically fixed inside the box body 1 located next to the cleaning tube 2, and a plurality of guide rods 11 that can horizontally pass through the baffle are horizontally fixed at equal intervals along the length direction of the side wall of the cleaning tube 2 facing the baffle, and each of the guide rods 11 is sleeved with a No. 1 spring 13, and both ends of the No. 1 spring 13 are respectively fixed to the cleaning tube 2 and the baffle.

[0047] In the above scheme, a roller is rotatably provided on the free end of each guide rod 11 to reduce the friction between the guide rod 11 and the inside of the box body 1 and increase the service life of both.

[0048] When in use, the rust removal liquid entering the cleaning tube 2 is sprayed toward the baffle through the spray holes on the surface thereof. Under the action of the impact force generated by the rust removal liquid spraying toward the baffle, the cleaning tube 2 is driven away from the baffle and the No. 1 spring 13 is stretched, and vibrates in the horizontal direction under the action of the No. 1 spring 13. On the one hand, the vibration enables the hardware accessories to swing left and right during the falling process so that the hardware accessories can have a stronger contact with the brush 6, which is equivalent to increasing the scraping force of the brush 6, so that the brush can brush off the rust stains on the surface of the hardware, and the rust stains adhering to the brush 6 inside can be shaken off and discharged from the bottom end of the cleaning tube 2, so as to realize automatic cleaning of the inner wall of the cleaning tube 2.

[0049] In a preferred embodiment of the present invention, the slideway 3 is composed of two support columns; wherein,

[0050] Two parallel support columns are spaced apart and fixedly arranged on the inner wall of the box body 1, and the facing surfaces of the two support columns are partially recessed inward to form a guide slot 16 adapted to the hardware accessories.

[0051] In the above scheme, the distance between the two support columns is smaller than the diameter of the hardware accessories. On the one hand, this is to allow the cleaned hardware accessories to fall from the bottom end of the cleaning tube 2 into the channel formed by the guide slide grooves 16 of the two support columns and slide out from the starting end along the inclined channel to achieve the function of automatic unloading. On the other hand, since there is a gap between the two support columns, the rust stains discharged from the bottom of the cleaning tube 2 can fall through the gap between the two support columns to avoid the rust stains accumulating on the slide 3.

[0052] In a preferred embodiment of the present invention, a filter cloth 4 for filtering rust stains is fixedly disposed horizontally inside the box body 1 between the slideway 3 and the rust removal liquid level.

[0053] In the above scheme, the filter cloth 4 plays the role of filtering rust stains, so that the rust stains discharged from the bottom of the cleaning pipe 2 can fall onto the filter cloth 4 through the gap between the two support columns, thereby preventing the rust removal liquid flowing out of the cleaning pipe 2 from flowing back to the bottom of the box body 1 and being mixed with impurities.

[0054] In a preferred embodiment of the present invention, the device further comprises: a receiving box 10; wherein,

[0055] A material receiving box 10 with an opening facing upward is fixedly arranged on one side of the box body 1 , and a discharge end of the slideway 3 passes through a side wall of the box body 1 and extends into the material receiving box 10 .

[0056] In the above solution, the cleaned hardware accessories are discharged from the cleaning pipe 2 and automatically enter the receiving box 10 through the slide 3 for collection, thereby realizing the function of automatic unloading.

[0057] In a preferred embodiment of the present invention, the device further comprises a vibration mechanism 7 for driving the cleaning tube 2 to vibrate in the horizontal direction, wherein the vibration mechanism 7 comprises: a feeler rod 701, a rack plate 702 and a gear 703; wherein,

[0058] A feeler rod 701 capable of pushing the cleaning tube 2 toward the baffle is horizontally penetrated through the side wall of the box body 1, and a rack plate 702 is horizontally fixedly provided at the end of the feeler rod 701 located outside the box body 1, and a gear 703 meshingly connected to the rack plate 702 is horizontally and rotatably provided on the box body 1 above the rack plate 702. A motor for driving the gear 703 to rotate is also horizontally fixedly provided on the box body 1, and the output shaft of the motor is coaxially connected to the rotating shaft of the gear 703 through a coupling.

[0059] In the above scheme, the gear 703 is an incomplete gear, so that when the motor drives the gear 703 to rotate, it can intermittently drive the rack plate 702 to push the touch rod 701 toward the cleaning tube 2 and push the cleaning tube 2 horizontally toward the baffle and compress the No. 1 spring 13. When the gear 703 falls out of the meshing relationship with the rack plate 702, the cleaning tube 2 moves away from the baffle under the action of the No. 1 spring 13, and pushes the touch rod 701 to drive the rack plate 702 to return to its initial position in the horizontal direction.

[0060] Therefore, by driving the gear 703 to rotate, the cleaning tube 2 can be vibrated in the horizontal direction through the cooperation of the rack plate 702 intermittently meshing with it and the No. 1 spring 13.

[0061] In a preferred embodiment of the present invention, a No. 2 spring 14 is also sleeved on the touch rod 701, and the two ends of the No. 2 spring 14 are respectively fixed on the box body 1 and the rack plate 702, and a roller that can abut against the cleaning tube 2 is rotatably provided on the end of the touch rod 701 located in the box body 1.

[0062] In the above solution, the second spring 14 can assist the first spring 13 in resetting the touch rod 701 and the rack plate 702. The second spring 14 is compressed when the touch rod 701 pushes the cleaning tube 2 toward the baffle.

[0063] When the feeler rod 701 pushes the cleaning tube 2 toward the baffle, the sliding friction between the feeler rod 701 and the cleaning tube 2 can be converted into rolling friction through the roller, so as to reduce the friction between the two, thereby extending the service life of the two.

[0064] In a preferred embodiment of the present invention, the discharge end of the feeding end 8 is connected to the top of the cleaning pipe 2 through a corrugated hose 9.

[0065] In the above scheme, the corrugated hose 9 is arranged at an angle, and its bottom end is connected to the top of the cleaning pipe 2, and its top end is connected to the bottom end of the feeding end 8, so that when the cleaning pipe 2 moves back and forth in the horizontal direction, the corrugated hose 9 can be extended and retracted to cooperate with its movement.

[0066] In a preferred embodiment of the present invention, a feeding mechanism 12 capable of intermittently feeding materials into the feeding end 8 is provided on one side of the box body 1, and the feeding mechanism 12 comprises: a feeding belt and a feeding roller; wherein,

[0067] At least two feeding rollers are horizontally and rotatably arranged on the top and the bottom of the box body 1, and the two feeding rollers are connected together through the feeding belt transmission. The feeding end is located above the feeding end 8 and the feeding belt is inclined and is opposite to the feeding roller. The side is evenly spaced and evenly concave inward to form a number of storage grooves 15 that are compatible with hardware accessories.

[0068] In the above solution, the end of the feeding roller of the feeding mechanism 12 located at the top of the box body 1 is connected to the rotating shaft of the gear 703 through a chain.

[0069] like Figure 2 and Figure 3 As shown, through the transmission of the chain, the vibration mechanism 7 can drive the feeding belt of the feeding mechanism 12 to run counterclockwise and tilted during operation. During the operation, the hardware accessories to be processed are placed in the storage grooves 15 of the feeding belt respectively, so that during the operation of the feeding belt, multiple hardware accessories placed on its surface at intervals can be intermittently put into the feeding end 8 and the hardware accessories can be intermittently put into the cleaning pipe 2 through the feeding end 8.

[0070] In summary, the surface treatment device for hardware accessories provided by the present invention overcomes the problem in the prior art that each hardware accessory needs to be clamped and fixed one by one by a supporting mechanism, and the part of the hardware accessory clamped by the supporting mechanism will not be processed, resulting in a processing dead corner. After processing, each hardware accessory needs to be removed from the supporting mechanism one by one, and continuity cannot be achieved, thereby reducing work efficiency.
