Description

Technical Field

[0001] This application relates to the technical field of screw manufacturing, and in particular to a protective oil coating device for the production of large hexagonal head self-tapping screws with cut-off ends. Background Technology

[0002] Currently, screws are widely used in various industries, and their production technology is relatively mature, with fully automated production lines available.

[0003] After the screws are manufactured, they generally need to be coated with protective oil. This can increase their gloss and help them preserve their shape. In the existing technology, the screws are usually placed in a centrifugal drum and the appropriate protective oil is poured in. After being spun dry, the protective oil adheres to the surface of the screws.

[0004] However, the actual products after oiling showed uneven oiling. Some screws stacked in the middle only had a small portion in contact with the protective oil, which affected the product quality. Utility Model Content

[0005] The purpose of this application is to provide a protective oil application equipment for the production of large hexagonal head self-tapping screws with cut-off ends, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides a protective oil coating equipment for the production of large hexagonal head self-tapping screws, employing the following technical solution:

[0007] A protective oil coating device for producing large hexagonal head self-tapping screws includes a frame with an openable and closable sealed door on the side. An oil storage tank and an oil coating and drying mechanism are installed inside the frame. The oil coating and drying mechanism includes a slide rail, a lifting frame, a lead screw, a drive motor, a rotating cylinder, a chain, and a servo reduction motor. The slide rail is vertically fixed inside the frame. The lifting frame is slidably connected to the slide rail, and a nut seat is fixed to the side of the lifting frame. The lead screw is rotatably connected inside the frame and matched with the nut seat. The drive motor is fixed inside the frame and drives the lead screw to rotate. The rotating cylinder is rotatably mounted on the lifting frame, and a driven sprocket is fixed to the side of the rotating cylinder. The servo reduction motor is fixed to the lifting frame, and a drive sprocket is fixed to the output shaft of the servo reduction motor. The drive sprocket and the driven sprocket are driven by a chain. A loading port is provided on the surface of the rotating cylinder, and a cover is matched and installed at the loading port.

[0008] The rotating cylinder is formed by folding and welding a perforated mesh, and the cover is also formed by processing a perforated mesh. Studs are welded around the filling port, and the cover is fixed to the filling port by nuts.

[0009] The oil storage tank is welded and fixed inside the frame, and the periphery of the oil storage tank and the inner wall of the frame form a rounded transition.

[0010] Preferably, a right-side lifting frame is fixed on the lifting frame, and the servo reduction motor is fixed on the right-side lifting frame.

[0011] A counterweight is fixed to the side of the lifting frame away from the servo reduction motor, and a left-side lifting frame is fixed to the lifting frame corresponding to the position of the counterweight.

[0012] By adopting the above technical solution and setting up a counterweight, the rotation of the rotating drum can be ensured to be stable. By setting up a right-side lifting frame and a left-side lifting frame, the counterweight and servo geared motor can be prevented from coming into contact with the protective oil, thereby avoiding any impact on the screws and workers during subsequent material handling.

[0013] A drain pipe is connected to the side of the oil storage tank.

[0014] In summary, this application includes at least one of the following beneficial technical effects: the protective oil coating equipment for producing large hexagonal head self-tapping screws with cut-off ends is equipped with an oil storage tank and an oil coating and drying mechanism. The rotating cylinder in the oil coating and drying mechanism can be immersed in the oil storage tank, and the rotating cylinder can also rotate to make the screws fall into the rotating cylinder, which can ensure that all screws can fully contact the protective oil. After immersion in oil, the oil coating and drying mechanism can also realize the drying action, which can complete the oil coating work of a large number of screws at one time, with high production efficiency and good screw product quality.

Detailed Implementation

[0019] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0020] This application discloses a protective oil coating device for the production of large hexagonal head self-tapping screws with cut-off ends, referring to... Figure 1-3 The system includes a frame 1, with an openable and closable sealed door 11 installed on the side. Inside the frame 1 is an oil storage tank 2 and an oiling and drying mechanism 3. To facilitate the recovery of protective oil, the oil storage tank 2 is welded and fixed inside the frame 1, and the periphery of the oil storage tank 2 has a rounded transition with the inner wall of the frame 1. The oiling and drying mechanism 3 includes a slide rail 31, a lifting frame 32, a lead screw 33, a drive motor, a rotating cylinder 34, a chain, and a servo reduction motor 35. The slide rail 31 is vertically fixed inside the frame 1, and the lifting frame 32 is slidably connected to the slide rail 31. The side of the lifting frame 32 is fixed. The machine has a nut seat, a lead screw 33 is rotatably connected to the frame 1 and matched with the nut seat, a drive motor is fixed in the frame 1 and is used to drive the lead screw 33 to rotate, a rotating cylinder 34 is rotatably mounted on the lifting frame 32, a driven sprocket 37 is fixed on the side of the rotating cylinder 34, a servo reduction motor 35 is fixed on the lifting frame 32, and a drive sprocket 36 is fixed on the output shaft of the servo reduction motor 35. The drive sprocket 36 and the driven sprocket 37 are driven by a chain. The surface of the rotating cylinder 34 is provided with a loading port, and a cover 38 is matched and installed at the loading port.

[0021] A drain pipe is connected to the side of the oil storage tank 2.

[0022] Reference Figure 2 and Figure 3 The rotating cylinder 34 is made of perforated mesh ring folded and welded, and the cover 38 is also made of perforated mesh. Stud posts 7 are welded around the filling port, and the cover 38 is fixed to the filling port by nuts.

[0023] Reference Figure 2 A right-side lifting frame 4 is fixed on the lifting frame 32, and a servo reduction motor 35 is fixed on the right-side lifting frame 4. A counterweight 5 is also fixed on the side of the lifting frame 32 away from the servo reduction motor 35, and a left-side lifting frame 6 is fixed on the lifting frame 32 at the position corresponding to the counterweight 5.

[0024] By setting up the counterweight 5, the rotating drum 34 can be rotated smoothly. By setting up the right lifting frame 4 and the left lifting frame 6, the counterweight 5 and the servo reduction motor 35 can be prevented from contacting the protective oil, thereby avoiding the impact on the screws and workers during subsequent material handling.

[0025] The implementation principle of the protective oil coating equipment for the production of large hexagonal head self-tapping screws according to an embodiment of this application is as follows:

[0026] In use, first remove the cap 38 from the rotating cylinder 34 by disengaging the male connector from the female connector. Then, place the screws to be oiled into the rotating cylinder 34 through the loading port. After that, replace the cap 38 and the sealing door 11 of the frame 1. Subsequently, the drive motor drives the lifting frame 32 downward via the lead screw 33. The lifting frame 32 drives the rotating cylinder 34 to immerse in the oil storage tank 2. During this process, the servo reduction motor 35 drives the rotating cylinder 34 to rotate slowly. The screws can flip inside the rotating cylinder 34, thus making full contact with the protective oil. After being immersed in oil for a period of time, the drive motor drives the lifting frame 32 to rise via the lead screw 33, causing the rotating cylinder 34 to detach from the oil storage tank 2. After the rotating cylinder 34 detaches from the oil storage tank 2, the servo reduction motor 35 increases the speed, causing the rotating cylinder 34 to rotate at high speed. Under centrifugal force, the protective oil on the surface of the screws is spun dry, thus completing the oiling work. The rotating cylinder 34 can complete the oiling work of a large number of screws at one time.

[0027] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
