Description
Technical Field
[0001] This utility model relates to the field of fastener technology, and in particular to a fastener sorting and packaging device. Background Technology
[0002] Fasteners play a vital role as an indispensable basic component in many fields of industrial production and manufacturing. There are many types of fasteners, including bolts, nuts, washers, screws, etc. Their specifications and dimensions vary significantly due to different application scenarios. The diversity of length specifications is particularly prominent. In the actual production process, fasteners are usually mass-produced. However, in the subsequent use, assembly or sales stages, they often need to be accurately screened and packaged according to specific specifications, especially length specifications. Traditional fastener sorting and packaging methods mainly rely on manual operation. Workers need to check the length of each fastener one by one and then classify them into different containers according to their length differences. Since human visual judgment has a certain error and is easily affected by factors such as fatigue and emotions, misjudgment is inevitable in actual operation, resulting in the incorrect classification of fasteners of different lengths, which affects product quality and production progress.

[0008] As a preferred embodiment of the fastener screening and packaging device of this utility model, the top of the box is inclined, the interior of the chamber is arc-shaped, the outer wall of the box is provided with a beveled edge, and a number of observation ports are provided at equal intervals on the beveled outer wall.
[0009] In a preferred embodiment of the fastener screening and packaging device of this utility model, the connecting disc is elliptical in shape, and the outer wall of the connecting disc is in contact with the lower outer wall of the irregular strip.
[0010] (III) Beneficial Effects This utility model provides a fastener sorting and packaging device. It has the following beneficial effects: 1. By setting up a screening component, it can be ensured that only fasteners within a specific length range can pass through smoothly, thereby achieving high-precision classification and screening of fasteners of different lengths, greatly reducing the errors that may occur during manual screening, thus ensuring the accuracy of screening and effectively improving overall production efficiency. 2. By setting up anti-stacking components, the irregular strips can reciprocate around the pivot pin, and the separation strips on the irregular strips also swing accordingly. During the swinging process, the separation strips will continuously move and separate the fasteners on the top of the connecting plate, breaking up any fasteners that may be piled up together. This allows them to be more evenly distributed on the top of the connecting plate and smoothly enter the subsequent screening stage. This effectively avoids problems such as screening blockage and inaccurate screening caused by fastener accumulation, ensuring the smooth progress of the screening process.

Detailed Implementation
[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0018] Example 1 Reference Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides a fastener screening and packaging device, including a box 1. The top of the box 1 is provided with a screening component 2 for screening fasteners of different lengths. One side of the box 1 is provided with an anti-stacking component 3 for preventing fasteners from accumulating. The screening component 2 includes a first limiting plate 201 symmetrically fixedly connected to the top of the box 1. The top of the box 1 is provided with a first limiting groove 202. The top of the box 1 is provided with a plurality of screening grooves 203 at equal intervals. The inside of the box 1 is provided with a plurality of chambers 204 at equal intervals. The lower end of the screening groove 203 communicates with the inside of the chamber 204.
[0019] Specifically, the top of the box 1 is inclined, the interior of the chamber 204 is arc-shaped, the outer wall of the box 1 has a beveled edge, and several observation ports 6 are equidistantly opened on the beveled outer wall.
[0020] Furthermore, when screening fasteners of different lengths, the operator first places the fastener to be screened on the top of the housing 1 near the starting end of the first limiting plate 201. Under the influence of its own weight, the fastener begins to move forward along the path defined by the first limiting plate 201 and the first limiting groove 202. As the fastener gradually approaches the screening groove 203 during its movement, fasteners of different lengths will exhibit different passage patterns. For fasteners whose length is less than the minimum length corresponding to a certain screening groove 203, due to their shorter length, their ends have not yet touched the edge of the screening groove 203 when they reach it. Therefore, it will continue to move forward along the top of the box 1 until it reaches the screening groove 203 of a suitable length. When the length of the fastener is within the length range corresponding to a certain screening groove 203, its end will be able to fall into the screening groove 203. Then, under the action of gravity, the fastener will pass through the screening groove 203 and smoothly enter the cavity 204 that is connected to the box 1. However, for fasteners whose length is greater than the maximum length corresponding to a certain screening groove 203, they will be blocked by the edge of the screening groove 203 due to their excessive length and will not be able to fall into the screening groove 203. Instead, they will continue to move forward to find a larger screening groove 203.
[0021] Example 2 Reference Figure 1 , Figure 3 and Figure 4 This is the second embodiment of the present invention. Based on the previous embodiment, the anti-stacking component 3 includes a connecting plate 301 fixedly connected to the outer wall of the box 1. A separation groove 302 is provided on the top of the connecting plate 301. A shaped strip 303 is rotatably connected to the outer wall of the connecting plate 301 through a shaft pin. The upper end of the shaped strip 303 extends to the top of the connecting plate 301, and the lower end of the shaped strip 303 extends to the bottom of the connecting plate 301. A plurality of separation strips 304 are symmetrically fixedly connected to the inner side of the shaped strip 303.
[0022] Specifically, a fixed base 305 is fixedly connected to the outer wall of the housing 1, a motor 306 is fixedly connected to the inner side of the fixed base 305, a rotating rod 307 is fixedly connected to the output end of the motor 306, a connecting plate 308 is fixedly connected to the end of the rotating rod 307 away from the motor 306, a second limiting plate is symmetrically fixedly connected to the top of the connecting plate 301, a second limiting groove is opened on the top of the connecting plate 301, the connecting plate 308 is elliptical, and the outer wall of the connecting plate 308 is in contact with the lower outer wall of the irregular strip 303.
[0023] Furthermore, to prevent fastener accumulation, the starting motor 306 drives the rotating rod 307 to rotate. The connecting disc 308 at the end of the rotating rod 307 moves in a circular motion with the rotating rod 307. Since the connecting disc 308 is elliptical, during rotation, its major axis and minor axis continuously and alternately contact the lower end of the irregular strip 303. When the major axis of the connecting disc 308 gradually approaches the lower end of the irregular strip 303, it will exert a squeezing effect on the lower end of the irregular strip 303, causing the irregular strip 303 to swing to one side around the shaft pin. As the connecting disc 308 continues to rotate, when its minor axis approaches the irregular strip... When the lower end of strip 303 is reached, the squeezing effect decreases, and the irregular strip 303 swings in the opposite direction under its own gravity, thus realizing reciprocating swing. During the reciprocating swing of the irregular strip 303, several symmetrically fixed separation strips 304 on its inner side also reciprocate. During the swing, the separation strips 304 will continuously insert between the stacked fasteners, and move and separate the fasteners. The swing of the separation strips 304 changes the relative position between the fasteners, and the originally tightly stacked fasteners are dispersed, thereby achieving the effect of preventing stacking.
[0024] Working principle: When screening fasteners of different lengths, the operator first places the fastener to be screened on the top of the housing 1 near the starting end of the first limiting plate 201. Under the influence of its own weight, the fastener moves forward along the path defined by the first limiting plate 201 and the first limiting groove 202. As the fastener moves closer to the screening groove 203, fasteners of different lengths will exhibit different passage patterns. For fasteners whose length is less than the minimum length corresponding to a certain screening groove 203, due to their shorter length, their ends have not yet touched the edge of the screening groove 203 when they reach it. Therefore, it will continue to move forward along the top of the box 1 until it reaches the screening groove 203 of a suitable length. When the length of the fastener is within the length range corresponding to a certain screening groove 203, its end will be able to fall into the screening groove 203. Then, under the action of gravity, the fastener will pass through the screening groove 203 and smoothly enter the cavity 204 that is connected to the box 1. However, for fasteners whose length is greater than the maximum length corresponding to a certain screening groove 203, they will be blocked by the edge of the screening groove 203 due to their excessive length and will not be able to fall into the screening groove 203. Instead, they will continue to move forward to find a larger screening groove 203. To prevent fastener accumulation, the motor 306 is started, driving the rotating rod 307 to rotate. The connecting disc 308 at the end of the rotating rod 307 moves in a circular motion with the rotating rod 307. Since the connecting disc 308 is elliptical, during rotation, its major and minor axes alternately contact the lower end of the irregular strip 303. When the major axis of the connecting disc 308 gradually approaches the lower end of the irregular strip 303, it exerts a squeezing effect on the lower end of the irregular strip 303, causing the irregular strip 303 to swing to one side around the shaft pin. As the connecting disc 308 continues to rotate, when its minor axis approaches the lower end of the irregular strip 303... At the lower end of 03, the squeezing effect decreases, and the irregular strip 303 swings in the opposite direction under its own gravity, thus realizing reciprocating swing. During the reciprocating swing of the irregular strip 303, several separation strips 304 symmetrically fixed on its inner side also reciprocate. During the swing, the separation strips 304 will continuously insert between the stacked fasteners, and move and separate the fasteners. The swing of the separation strips 304 causes the relative position between the fasteners to change, and the originally tightly stacked fasteners are dispersed, thereby achieving the effect of preventing stacking.
