Description

Technical Field

[0001] This utility model relates to the field of parts screening technology, and in particular to a three-drive roller parts screening machine for chain parts rollers. Background Technology

[0002] After machining and heat treatment, chain components such as rollers and bushings are contaminated with numerous impurities on their surface and inside, mainly including oxide scale, metal shavings, broken parts, and other parts of different specifications mixed in from the heat treatment mesh belt furnace. These impurities not only affect the appearance quality of the product but also adversely impact subsequent assembly and performance. Previously, vibratory feeders and manual sorting were used, but vibratory feeder sorting is noisy, and manual sorting is inefficient. Therefore, a three-drive roller parts sorting machine is essential. Utility Model Content

[0003] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a three-drive roller parts screening machine, comprising:

[0004] A hopper is used to store parts and has several discharge ports.

[0005] The material feeding control assembly includes several control components that can move axially (i.e., up and down) at the discharge port, and the control components are provided with material feeding channels;

[0006] A guide plate, at least partially installed below the material discharge channel;

[0007] Vibration assembly that drives the guide plate to vibrate;

[0008] The outlet of the screen cylinder and the guide plate extends at least partially into the screen cylinder.

[0009] Two vertical plates are fixed to the lower surface of the hopper located on both sides of the discharge port. A first horizontal plate is fixed between the two vertical plates. At least one guide channel is opened on the first horizontal plate. A guide post is arranged in the guide channel. The guide post moves axially in the guide channel. A feeding plate is fixedly connected to the guide post located above the first horizontal plate. Several through holes are opened on the feeding plate. The feeding channel of the control component is connected to the through holes and the control component is fixed on the feeding plate. The feeding plate is installed on the guide plate.

[0010] The guide post is fixed below the first horizontal plate and a third horizontal plate is provided. A second horizontal plate is provided between the first horizontal plate and the third horizontal plate. The second horizontal plate has a guide hole for the guide post to pass through.

[0011] A first transmission component is rotatably connected to the third horizontal plate, and a first eccentric wheel is rotatably connected to the first transmission component. The first drive motor also includes an output shaft that drives the first eccentric wheel to rotate. The output shaft of the first drive motor controls the rotation of the first eccentric wheel via a first belt drive, thereby realizing the up-and-down movement of the third horizontal plate. Since guide posts are fixedly connected to the first horizontal plate, the feeding plate also moves up and down, which drives the control component to move up and down so that parts located in the hopper can enter the guide plate from the feeding channel.

[0012] It also includes a first connecting plate, the two ends of which are connected to the guide plate and the second horizontal plate pivot, respectively.

[0013] It also includes a second connecting plate, and a hollowed-out section is provided on the third horizontal plate. The second connecting plate passes through at least part of the hollowed-out section. The second connecting plate located above the third horizontal plate is connected to the pivot of the second horizontal plate. A second eccentric wheel is rotatably connected to the second connecting plate located below the third horizontal plate.

[0014] It also includes a frame, with a second drive motor fixed to a third horizontal plate. The output shaft of the second drive motor drives the eccentric shaft of the second eccentric wheel to rotate via a belt, thereby driving the second connecting plate to move up and down, and in turn driving the second horizontal plate to move up and down to generate vibration. The first drive motor is fixed to the first horizontal plate.

[0015] A third drive motor is also fixed on the frame. Transmission teeth are provided on the outer periphery of the screen cylinder. A transmission rod is rotatably connected to the frame. The frame also includes a rotatably connected transmission wheel that meshes with the transmission teeth. The third drive motor drives the transmission wheel to rotate, thereby driving the screen cylinder to rotate.

[0016] A chip discharge plate is fixed on the frame below the screen cylinder.

[0017] Compared with the prior art, the present invention has the following advantages: The present invention has a simple structure. The bottom of the hopper has several discharge ports for screening parts. Cylindrical control components are evenly distributed at the bottom. The cylinders are processed so that the material discharge channel is slightly larger than the size of the parts. When the control components move up and down, the parts can pass through the material discharge channel to the guide plate. During this process, impurities such as oxide scale after heat treatment and processing metal chips will fall off. Parts larger than the material discharge channel will remain in the hopper and be manually removed later.

[0018] The first drive motor controls the first eccentric wheel to achieve the up-and-down reciprocating motion of the control component; the second drive motor controls the shaking of the guide plate; and the third drive motor controls the rotation of the screen cylinder.

[0019] The cylindrical control components can be replaced according to different part sizes. The aforementioned belt and pulley transmission method can also be a sprocket and chain transmission method. Attached Figure Description

[0040] It also includes a frame 21, with a second drive motor 22 fixed on the third horizontal plate 11. The output shaft of the second drive motor 22 drives the eccentric shaft of the second eccentric wheel 20 to rotate via a belt, thereby driving the second connecting plate to move up and down, and in turn driving the second horizontal plate 10 to move up and down to generate vibration.

[0043] Compared with the prior art, the present invention has the following advantages: The present invention has a simple structure. The bottom of the hopper 1 is provided with several discharge ports 101 for screening parts. Cylindrical control components 201 are evenly distributed at the bottom. The cylinders are processed so that the discharge channel 202 is slightly larger than the size of the parts. When the control component 201 moves up and down, the parts can pass through the discharge channel 202 to the guide plate 3. During this process, impurities such as oxide scale after heat treatment and processing metal chips will fall off. Parts larger than the discharge channel 202 will remain in the hopper 1 and be manually removed later.

[0044] The first drive motor 15 controls the first eccentric wheel 14 to realize the up-and-down reciprocating motion of the control component 201; the second drive motor 22 controls the shaking of the guide plate 3; and the third drive motor 23 controls the rotation of the screen cylinder 5, so that the parts can tumble inside the screen cylinder 5 and shake out impurities, iron filings, etc.

[0045] The cylindrical control component 201 can be replaced according to different part sizes. The aforementioned belt and pulley transmission method can also be a sprocket and chain transmission method.

[0046] The screen cylinder 5 includes several cylindrical bars 28 spaced apart, with the spacing being smaller than that of the gears in the parts. Iron rings 25 can also be installed in the middle of the bars to increase rigidity and ensure that the bars 28 in the middle do not expand outward, thus ensuring the consistency of the spacing size. The iron rings 25 can also move in the transmission groove 29 installed outside the transmission rod 24.
