Description

Technical Field

[0001] The utility model relates to the technical field of screening devices, in particular to a screw screening device. Background Art

[0002] Automatic nail feeding machines have been used in the manufacturing industry for many years. However, due to the insufficient precision of the screws or the mixing of similar screws, problems such as nail jamming and material mixing often occur. This not only affects efficiency, but also poses a risk to assembly quality. Therefore, a screw screening device is needed to screen the screws and remove unsuitable screws.

[0003] In the prior art, an image recognition camera is added to the port of the direct vibration section (nail outlet) to identify the size and model of the screws. The screws are adjusted in direction (nut upward) by a circular vibration plate and arranged in order in the direct vibration section. The newly added image recognition camera takes a photo of the first screw for comparison. Unqualified screws are pushed into the isolation cavity by the cylinder, and qualified screws are sent to the nail outlet tube by the cylinder and blown out to the nail outlet by high-pressure gas. However, in actual use, the camera is expensive, and the recognition accuracy varies greatly in different application environments. The phenomenon of "high investment and low return" may occur. The peripheral requirements such as lighting, installation angle, and visual range are high, and debugging and maintenance are difficult. After some oversized screws enter the direct vibration track, nail jamming will occur, requiring shutdown for maintenance, affecting efficiency. Therefore, it is necessary to improve a screw screening device to solve the above problems. Utility Model Content

[0028] The screw screening mechanism 2 includes a screening component 21 and a collecting component 22 . The collecting component 22 is arranged at the bottom of the screening component 21 .

[0029] Furthermore, the screening component 21 includes a fixed column 211, which is fixedly installed on the top of the base plate 1, a flange mounting plate 212 is fixedly installed on the front of the fixed column 211, a cylinder 213 is provided on the front of the flange mounting plate 212, a push block 214 is fixedly installed on the front of the cylinder 213, a double-sided bridge channel 215 is fixedly installed on the inner side of the fixed frame 4, and an auxiliary side block 216 and an inclined single-sided bridge channel 217 are fixedly installed on the front of the double-sided bridge channel 215, so as to facilitate the screening of screws through the screening component 21.

[0030] Furthermore, the auxiliary side block 216 is arranged on the right side of the inclined single-side bridge flow channel 217, and the push block 214 is slidably installed inside the double-side bridge flow channel 215, so as to facilitate the movement of the screw under normal conditions.

[0031] Furthermore, the collecting component 22 includes a fixed seat 221, which is fixedly installed on the top of the base plate 1, a slide rod seat 222 is slidably installed inside the fixed seat 221, a mounting plate 223 is fixedly installed on the top of the slide rod seat 222, an isolation box 224 is slidably installed on the top of the mounting plate 223, a side ear 225 is fixedly installed on the outer side of the isolation box 224, a bolt 226 is arranged inside the side ear 225, a cylinder 227 is fixedly installed on the top of the base plate 1, a connecting plate 228 is fixedly installed on the back of the cylinder 227, so as to facilitate uniform collection through the screws of the collecting component 22.

[0032] Furthermore, the top of the connecting plate 228 is fixedly mounted to the bottom of the mounting plate 223, and the bolts 226 are threadedly mounted inside the mounting plate 223, thereby improving the stability of the fixation.

[0033] Embodiment two:

[0034] See also Figure 5-6 , and combined with Example 1, it is further obtained that the feeding mechanism 3 includes an inclined frame 31, the inclined frame 31 is fixedly installed on the inner side of the fixed frame 2 5, the inner side of the inclined frame 31 is fixedly installed with a fixed inclined plate 32, the front of the inclined frame 31 is fixedly installed with a feed hopper 33, the interior of the inclined frame 31 is provided with a feeding guide rail 34, the right side of the feeding guide rail 34 is fixedly installed with a lower hopper 35, the bottom inner side of the inclined frame 31 is fixedly installed with a cylinder 36, the top of the cylinder 36 is fixedly installed with a connecting frame 37, and the top of the connecting frame 37 is fixedly installed with a movable inclined plate 38, which is convenient for feeding screws through the feeding mechanism 3.

[0035] Furthermore, the movable inclined plate 38 is slidably mounted on the inner side of the fixed inclined plate 32, and the movable inclined plate 38 is slidably mounted on the inner side of the inclined frame 31, so as to facilitate loading in a normal state.

[0036] In actual operation, when the device is used, the screws are poured into the feed hopper 33. Under the action of the tilted feed hopper 33, the screws are close to the fixed inclined plate 32. At this time, the cylinder 3 36 is driven to make the connecting frame 37 drive the movable inclined plate 38 to rise. The movable inclined plate 38 pushes the screws to rise. After the screws rise to each layer, they will be close to the fixed inclined plate 32 due to the tilt. When the screws are pushed to the highest layer, they will fall into the feeding guide rail 34. The feeding guide rail 34 transports the screws to the inside of the lower hopper 35. Through the tilted lower hopper 35, the screws slide into the inside of the double-sided bridge flow channel 215, driving the cylinder 1 213 to make the push block 214 repeatedly push the screws. When the side bridge flow channel 215 is in contact with the auxiliary side block 216, the smaller screws will fall into the rear storage groove of the isolation box 224. With the push of the push block 214, the screws enter the inner side of the auxiliary side block 216 and the inclined single-side bridge flow channel 217. Under the action of gravity, the screws slide downward. When they are not in contact with the auxiliary side block 216, the screws that are too long or have too large nuts will have their center of gravity deviated to the outside under the action of gravity and fall into the front storage groove of the isolation box 224. By driving the cylinder 227, the mounting plate 223 drives the isolation box 224 to transmit, so that the screws inside the isolation box 224 can be evenly spread and collected evenly. By removing the bolts 226, the isolation box 224 can be disassembled and the screws can be collected.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
