Screw workpiece screening disc adjusting mechanism

Abstract

The utility model relates to a screw workpiece screening disc adjusting mechanism which comprises a vibrating mechanism, the upper portion of the vibrating mechanism is connected with a screening unit, the screening unit comprises a frame body, a screening disc is arranged in the frame body and comprises a plurality of rod bodies which are arranged at intervals, and each rod body is separated from the adjacent rod body by a distance. And the screening disc is movably connected with the frame body. Due to the fact that the screening disc is movably connected with the frame body, when screw workpieces of different sizes or specifications penetrate through one guide hopper arranged at the top of the screening unit and fall on the screening disc, only the original screening disc is replaced, and another screening disc is used for replacing the original screening disc. For example, the distance between each rod body and the adjacent rod body of the other screening disc is larger than or smaller than the distance between each rod body and the adjacent rod body of the original screening disc, so that the screw screening disc is economical and adapts to the specifications or sizes of various screw workpieces.

Description

Technical Field

[0001] This utility model belongs to the field of mechanical equipment technology, and in particular to a screw workpiece screening device. Background Technology

[0002] Screws, which are widely used in industry, often have cooling, lubricating or rust-preventing oils attached to them after manufacturing due to the process. At the same time, metal shavings are also attached due to various processing steps. Before the finished product is completed, the screw workpieces are usually processed separately by a sorting tray, vibrating feeder or other means.

[0003] The vibrating feeder typically includes a vibrating mechanism, with a screening unit connected to the upper part of the vibrating mechanism. The screening unit includes a frame, and a screening disc is provided inside the frame. The screening disc includes a plurality of spaced rods, with each rod spaced apart from its adjacent rods to allow metal shavings or lubricating and rust-preventing oils to fall through, since shavings are not easy to clean if they fall into the machine.

[0004] However, the spacing between each rod of the screening disc and its adjacent rods is a fixed size. Therefore, when screws of different sizes or specifications fall onto the screening disc, if the screw is too small (relatively large spacing), it may fall directly through the spacing, making it difficult to process. Alternatively, if the screw is too large (relatively small spacing), metal shavings or lubricating and anti-rust oil generated during the screw conveying process may clog and be difficult to drain. Replacing the vibrating feeder would be too costly and would affect the smoothness of the process and production efficiency. Summary of the Invention

[0005] In view of this, the present invention provides a screw workpiece screening disc adjustment mechanism to solve the above problems.

[0006] A screw workpiece screening disc adjustment mechanism includes a vibration mechanism. The upper part of the vibration mechanism is connected to a screening unit. The screening unit includes a frame, and a screening disc is disposed in the frame. The screening disc includes a plurality of spaced rods, each rod being spaced apart from its adjacent rod by a distance. The screening disc and the frame are movably connected.

[0007] Furthermore, each side of the frame is provided with a lip, and each side of the screening disc is provided with a retaining edge. Each retaining edge extends downward to a resisting member against the bottom surface of the frame. Each frame is also provided with an adjusting screw, which can pass through each lip to dynamically press or loosen the retaining edge.

[0008] Furthermore, an oil filter screen is provided at the bottom of the screening disc, and an oil collection tray is provided below the oil filter screen within the frame, with a conduit provided on the side of the oil collection tray.

[0009] Compared with the prior art, the screw workpiece screening disc adjustment mechanism provided by this utility model includes a vibration mechanism. The upper part of the vibration mechanism is connected to a screening unit. The screening unit includes a frame, and a screening disc is disposed within the frame. The screening disc includes a plurality of spaced-apart rods, each rod being spaced apart from its adjacent rods by a distance. The screening disc and the frame are movably connected. Because the screening disc and the frame are movably connected, when screw workpieces of different sizes or specifications fall onto the screening disc through a guide hopper located at the top of the screening unit, only the original screening disc needs to be replaced with another suitable screening disc. For example, the distance between each rod of the other screening disc and its adjacent rods may be greater than or less than the distance between each rod of the original screening disc and its adjacent rods. Therefore, this invention can more economically adapt to various specifications or sizes of screw workpieces. Attached Figure Description

[0015] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.

[0016] Please see Figure 1 ,Cooperate Figure 2As shown, this invention relates to a screw workpiece screening disc adjustment mechanism, including a vibration mechanism 1. The upper part of the vibration mechanism 1 is connected to a screening unit 2. The screening unit 2 includes a frame 21, and a screening disc 22 is provided inside the frame 21. The screening disc 22 includes a plurality of spaced rods 221, each rod 221 being spaced apart from its adjacent rods 221 by a distance A. The screening disc 22 and the frame 21 are movably connected. Since the screening disc 22 is movably connected to the frame 21, when screw workpieces of different sizes or specifications fall onto the screening disc 22 through a guide hopper 3 located at the top of the screening unit 2, only the screening disc 22 can be replaced with another screening disc 22A as shown in the third figure. The other screening disc 22A includes a plurality of spaced rods 221A, each rod 221A being spaced apart from its adjacent rods by a distance B greater than the spacing A.

[0017] The screening disc 22 and the frame 21 are movably connected in a manner that allows for multiple pathways to be achieved, in conjunction with... Figure 1 , Figure 2 As shown in the preferred embodiment of the present invention, each side of the frame 21 is provided with a lip 211, and each side of the screening disc 22 is provided with a retaining edge 222, and each retaining edge 222 extends downward to a resisting member 223 that abuts against the bottom surface 213 of the frame 21.

[0018] Cooperate Figure 5 As shown, a connecting piece 226 is provided between each rod 221 and the resisting member 223. The length of the connecting piece 226 is usually greater than that of the screw workpiece in the working state, so that the screw workpiece can be suspended at a distance A between the two rods 221.

[0019] In addition, each frame 21 is provided with an adjusting screw 212, which can be inserted through each lip 211 to dynamically press or loosen the fixed edge 222.

[0020] Please see Figure 4 As shown, the present invention features an oil filter screen 224 at the bottom of the screening disc 22 to allow rust-preventive oil to seep through the mesh of the oil filter screen 224. Below the oil filter screen 224, an oil collection tray 225 is provided inside the frame 21 to collect the rust-preventive oil that seeps through the mesh of the oil filter screen 224. A conduit 225A is provided on the side of the oil collection tray 225 to allow the rust-preventive oil to be discharged, collected, and recycled into the machine for subsequent use.

[0021] Compared with the prior art, the screw workpiece screening disc adjustment mechanism provided by this utility model includes a vibration mechanism 1. The upper part of the vibration mechanism 1 is connected to a screening unit 2. The screening unit 2 includes a frame 21. A screening disc 22 is provided inside the frame 21. The screening disc 22 includes a plurality of spaced rods 221. Each rod 221 is spaced apart from its adjacent rods 221 by a distance A. The screening disc 22 and the frame 21 are movably connected. Since the screening disc 22 is movably connected to the frame 21, when screw workpieces of different sizes or specifications fall onto the screening disc 22 through a guide hopper 3 located at the top of the screening unit 2, only the original screening disc 22 can be replaced with another suitable screening disc 22A. For example, the distance B between each rod 221A of the other screening disc 22A and its adjacent rod 221A is greater than or less than the distance A between each rod 221 and its adjacent rod 221 of the original screening disc. Thus, this invention can more economically adapt to various specifications or sizes of screw workpieces.
