Description

[Technical field]

[0001] The utility model relates to the technical field of screw production, in particular to the technical field of an automatic chip removal, oil removal and discharge device for screws. [Background technology]

[0002] Screw refers to screws. Screws are tools that use the physics and mathematical principles of the circular rotation of the inclined surface of an object and the friction force to gradually fasten objects and machine parts. Screw is a general term for fasteners and a daily colloquialism. Screws are an indispensable industrial necessity in daily life: such as the very small screws used in cameras, glasses, clocks, electronics, etc.; general screws for televisions, electrical products, musical instruments, furniture, etc.; large screws and nuts are used in engineering, construction, and bridges; transportation equipment, airplanes, trams, cars, etc. use both large and small screws. Screws have important tasks in industry, and as long as there is industry on the earth, the function of screws will always be important.

[0003] During the screw production process, a layer of oil will be attached to the surface of the screw after it is manufactured. Therefore, the screw needs to be cleaned to remove the oil attached to the surface of the screw. In the prior art, a water spray cleaning machine is usually used to remove the oil on the surface of the screw. However, in actual use, due to factors such as short water spraying time and small contact area between the screw and water, the water washing degreasing effect is not ideal.

[0004] In order to solve the problems raised in the background technology, publication number CN209077329U discloses a screw degreasing machine, which is used to send the screws into warm water treated by a heating module and an ultrasonic module for degreasing and cleaning. The oil stains attached to the surface of the screws will float on the water surface, and the clean water at the bottom is transported to the nozzle by a water pump provided at the bottom of the box. The screws that have been cleaned are rinsed by the nozzle to clean the screws with secondary oil stains on the surface. However, the structure still has the following shortcomings:

[0005] 1. Although this structure can remove oil stains on the surface of the screw, some debris is stuck on the surface of the screw during the production process, and this structure lacks a debris removal device, so it is easy to damage the surface quality of the product and reduce the qualified rate.

[0006] 2. In this structure, after the screws are degreased, the workers need to collect them manually, which reduces the processing efficiency and is time-consuming and labor-intensive. [Contents of the utility model]

[0007] The purpose of the utility model is to solve the problems in the prior art and to propose an automatic chip removal, oil removal and discharge device for screws, which can automatically remove oil stains and debris on the surface of the screws and automatically complete the discharge work, has a high degree of automation, saves time and labor, and improves processing efficiency.

[0008] To achieve the above-mentioned objectives, the utility model proposes an automatic chip removal, oil removal and discharging device for screws, comprising a feed box, a discharging hopper, a frame, an oil removal mechanism, a vibrating screen, a vibrating motor, a collecting mechanism and a controller, wherein the feed port of the feed box is located at the top, the discharging port of the feed box is located at the bottom, the discharging port of the feed box is communicated with the discharging hopper, the discharging hopper is arranged to be inclined downward, the discharging port of the discharging hopper is connected to the frame, the interior of the frame is provided with an oil removal mechanism on one side close to the discharging hopper, the oil removal mechanism is used to remove oil stains on the surface of the screw, a vibrating screen is arranged below the oil removal mechanism, a vibrating motor matched with the vibrating screen is arranged on the outer wall of the frame, the output end of the vibrating motor passes through the frame and is connected to the vibrating screen, the bottom of the frame is connected with the collecting mechanism, the collecting mechanism is used to collect chips and oil stains, the side wall of the frame is provided with a controller, and the controller is electrically connected to the input end of the vibrating motor.

[0009] Preferably, the oil removal mechanism includes an upper cross bar, an upper roller, a lower cross bar, and a lower roller. The upper cross bar is arranged in the middle position of the frame, and a plurality of upper rollers parallel to each other are arranged between the upper cross bar and the inner side wall of the frame. The lower cross bar is arranged below the upper cross bar, and a plurality of lower rollers parallel to each other are arranged between the lower cross bar and the inner side wall of the frame. The lower rollers and the upper rollers are arranged alternately up and down.

[0010] Preferably, a movable groove is provided at the lower middle portion of the frame, and adjustment components are connected to both ends of the lower cross bar, so that the lower cross bar can move up and down in the movable groove through the adjustment components.

[0011] Preferably, the adjustment assembly includes a mounting seat, a threaded rod, and a locking nut. The mounting seat is symmetrically installed on the outer side wall of the frame, one end of the threaded rod passes through the mounting seat and is connected to the lower cross bar, and the other end of the threaded rod is equipped with a locking nut.

[0012] Preferably, the collecting mechanism comprises an oil collecting box, a connecting rod, and a debris collecting net; the oil collecting box is connected to the bottom of the frame via the connecting rod, and a debris collecting net is provided above the oil collecting box.

[0013] Beneficial effects of the utility model:

[0014] The utility model can automatically remove the oil stains and debris on the surface of the screw through the coordinated use of the oil removal mechanism, the vibrating screen, the vibrating motor and the collecting mechanism. First, the screw to be cleaned is poured into the feed box and falls into the oil removal mechanism through the discharging hopper. Through the mutual contact of the upper roller, the lower roller and the surface of the screw, the oil stains can be adhered to and transferred to the upper roller and the lower roller, and then the upper roller and the lower roller gather and drip into the oil collecting box below. After passing through the upper roller and the lower roller, the screw falls into the vibrating screen, and the vibrating motor is started. The vibrating motor drives the vibrating screen to vibrate reciprocatingly, thereby shaking off the debris on the surface of the screw and dropping it onto the debris collecting net, which is convenient for the staff to collect uniformly later. Then, the screw is slowly discharged from the discharging port on one side of the frame under the action of the vibrating screen, and falls into the external collecting barrel, thereby automatically removing the oil stains and debris on the surface of the screw, and automatically completing the discharging work. The automation degree is high, the qualified rate of products is improved, time and labor are saved, and the processing efficiency is improved, and the problem of reducing the qualified rate of products and being unable to collect automatically is solved.
