Description

Technical Field

[0001] The utility model relates to the technical field of machinery manufacturing, in particular to a nut processing and screening device. Background Technique

[0002] With the rapid development of the manufacturing industry and the increasing maturity of automation technology, nuts, as key components in mechanical connections, their processing quality and screening efficiency are directly related to the overall performance and market competitiveness of products.

[0003] In the existing rapid screening during the nut production process, baffles are usually erected on the nut transportation production line to block nuts that do not meet the size requirements, thereby screening the nuts. However, due to the relatively high speed of nut feeding during nut production and transportation, it is easy to cause nut accumulation, which not only affects the screening efficiency and accuracy of nuts, but also easily causes nut damage.

[0004] Therefore, a nut processing and screening device is now developed, which can buffer the nut feeding speed, avoid nut accumulation on the conveyor rack, and improve the screening accuracy and efficiency of nuts. Content of the Utility Model

[0005] In order to overcome the shortcomings of the existing nut screening device in the nut production process, where the nut feeding speed is relatively high during nut production and transportation, which is easy to cause nut accumulation, not only affecting the screening efficiency and accuracy of nuts, but also easily causing nut damage, the utility model provides a nut processing and screening device that can buffer the nut feeding speed, avoid nut accumulation on the conveyor rack, and improve the screening accuracy and efficiency of nuts.

[0006] The technical solution is as follows: A nut processing and screening device includes a conveyor rack, a baffle, a first collection box, a box door, a second collection box, and a buffer mechanism. A baffle is connected to the upper side of the right part of the conveyor rack, a first collection box is connected to the front side of the conveyor rack, a box door is rotatably connected to the front side of the first collection box, a second collection box is connected to the right side of the conveyor rack, and a buffer mechanism capable of buffering the nut feeding is provided on the conveyor rack.

[0007] Optionally, the baffle is of an inclined structure.

[0008] Optionally, a handle is provided on the box door.

[0009] Optionally, the buffer mechanism includes an inclined plate, a blocking plate, a fixed seat, a buffer plate, a coil spring, and a placement plate. The inclined plate is connected to the left side of the conveyor rack, the blocking plates are connected to the upper sides of the front and rear parts of the inclined plate, the fixed seats are connected to the inner sides of the left and right parts of the blocking plates, the buffer plates are rotatably connected to the fixed seats, coil springs are connected between the buffer plates and the adjacent fixed seats, and the placement plate is connected to the left side of the inclined plate.

[0010] Optionally, it further includes a scraping mechanism, which includes a servo motor, a reciprocating lead screw, a guide rod and a scraper. A servo motor is connected to the front side of the upper part of the baffle. A reciprocating lead screw is connected to the output shaft of the servo motor. The reciprocating lead screw is rotatably connected to the baffle. A guide rod is connected to the upper side of the left part of the baffle. A scraper is threadedly connected to the bidirectional lead screw, and the scraper is slidably connected to the guide rod.

[0011] Optionally, the scraper is of an L-shaped structure.

[0012] The beneficial effects of the present utility model are as follows: 1. When the nut slides off the inclined plate in the present utility model, the buffer plate rotates, and the coil spring deforms, so that the buffer plate buffers the nut and slows down the feeding rate of the nut, achieving the effect of being able to buffer the feeding speed of the nut, avoiding the accumulation of nuts on the conveyor rack, and improving the screening accuracy and efficiency of the nuts.

[0013] 2. By starting the servo motor in the present utility model, the reciprocating lead screw rotates, so that the scraper slides back and forth on the guide rod, and the scraper pokes and levels the nuts accumulated on the left side of the baffle, achieving the effect of being able to poke the nuts through the scraper to prevent the nuts from accumulating on the left side of the baffle and affecting the normal screening efficiency of the nuts.

Detailed Embodiment

[0019] The following describes the embodiments of the present utility model with reference to the drawings.

[0020] A nut processing and screening device, as Figure 1 and Figure 2As shown in the figure, it includes a conveyor rack 1, a baffle 2, a first collection box 3, a box door 4, a second collection box 5 and a buffer mechanism 6. On the upper side of the right part of the conveyor rack 1, there is a connected baffle 2. The baffle 2 is of an inclined structure, which is convenient for guiding nuts. In the front of the conveyor rack 1, there is a connected first collection box 3. In the front of the first collection box 3, there is a rotatably connected box door 4. There is a handle on the box door 4, which is convenient for opening. On the right side of the conveyor rack 1, there is a connected second collection box 5. There is a buffer mechanism 6 on the conveyor rack 1.

[0021] As Figure 1 and Figure 3 As shown in the figure, the buffer mechanism 6 includes an inclined plate 61, a blocking plate 62, a fixed seat 63, a buffer plate 64, a coil spring 65 and a placement plate 66. On the left side of the conveyor rack 1, there is a connected inclined plate 61. On the upper sides of the front and rear parts of the inclined plate 61, there are connected blocking plates 62. On the inner sides of the left and right parts of the blocking plate 62, there are connected fixed seats 63. On the fixed seats 63, there are rotatably connected buffer plates 64. Between the buffer plates 64 and the adjacent fixed seats 63, there are connected coil springs 65. On the left side of the inclined plate 61, there is a connected placement plate 66.

[0022] When using the present utility model, first place the conveyor rack 1 in the processing area of the nuts, so that the placement plate 66 is docked with the production line of the nuts, so that the nuts to be screened are transported from the placement plate 66 to the inclined plate 61, and the nuts slide down from the inclined plate 61 to the conveyor rack 1 below. When the nuts slide down from the inclined plate 61, they contact the buffer plate 64 on the fixed seat 63, causing the buffer plate 64 to rotate and the coil spring 65 to deform, so that the buffer plate 64 buffers the nuts, slows down the feeding rate of the nuts, and at the same time scatters the nuts piled up together, so that the nuts are evenly fed onto the conveyor rack 1. Then start the conveyor rack 1, so that the conveyor rack 1 transports the nuts from left to right. When the nuts are transported to the position of the baffle 2, the smaller nuts will pass through between the baffle 2 and the conveyor rack 1 and thus be transported to the second collection box 5 for collection. The larger nuts are blocked by the baffle 2, and at the same time under the guiding action of the baffle 2, the larger nuts slide into the first collection box 3 for collection. After the collection is completed, the box door 4 can be rotated to open to take out the nuts in the first collection box 3, thus playing a role in buffering the feeding speed of the nuts, avoiding the accumulation of nuts on the conveyor rack 1, and improving the screening accuracy and screening efficiency of the nuts.

[0023] As Figure 1 and Figure 4As shown in the figure, it further includes a scraping mechanism 7. The scraping mechanism 7 includes a servo motor 71, a reciprocating lead screw 72, a guide rod 73 and a scraper 74. A servo motor 71 is connected to the front side of the upper part of the baffle 2. A reciprocating lead screw 72 is connected to the output shaft of the servo motor 71. The reciprocating lead screw 72 is rotatably connected to the baffle 2. A guide rod 73 is connected to the upper side of the left part of the baffle 2. A scraper 74 is threadedly connected to the bidirectional lead screw. The scraper 74 is slidably connected to the guide rod 73. The scraper 74 is of an L-shaped structure.

[0024] By using the scraping mechanism 7 of the present device, the nuts in front of the baffle 2 can be toggled. When screening the nuts, start the servo motor 71 to make the reciprocating lead screw 72 rotate. Under the action of the thread, the scraper 74 reciprocates back and forth on the guide rod 73, so that the scraper 74 toggles and levels the nuts piled up on the left side of the baffle 2, thus playing the role of being able to toggle the nuts through the scraper 74 to prevent the nuts from piling up on the left side of the baffle 2 and affecting the normal screening of the nuts.

[0025] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
