Description

Technical Field

[0001] This utility model relates to a sorting device, and more particularly to a nut and washer sorting device. Background Technology

[0002] Manual assembly and disassembly require a large number of nuts and washers. Nuts are usually combined with screws to fasten the nuts, while washers distribute the load, increase wear resistance, and prevent the nuts from loosening due to vibration. Various types of washers are often mixed together. After use, the same washers need to be sorted and placed together, which requires the use of a sorting device.

[0003] For example, a nut and washer sorting device, as disclosed in Chinese Patent Publication No. CN204866546U, includes a parallel support base and a side fixing plate. One end of a connecting shaft is coaxially fixed to a handwheel, and the other end passes through a through hole in the support base and engages with a left connecting sleeve on the end face of the separation box. The right connecting sleeve on the other end face of the separation box is fitted with a fixing shaft on the side wall of the side fixing plate. The separation box has a hexagonal cross-section and is connected to a cover plate via a locking device and hinges. Each ridge on the side of the separation box forms multiple separation box outlet holes, and a collection box is placed under the separation box. This utility model utilizes the difference in axial dimensions between nuts and washers, and achieves the sorting of washers of different specifications through a rotating separation box, reducing sorting time and improving work efficiency.

[0004] The existing nut and washer sorting device has some problems. First, the rotating separation box disturbs the nuts and washers inside, causing them to collide with each other and damaging their surfaces, thus affecting their quality. Second, the separation box uses its outlet to screen the nuts and washers, but it cannot screen washers of other specifications and models. Utility Model Content

[0005] The purpose of this invention is to provide a nut and washer sorting device to solve the existing problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a nut and washer sorting device, including a nut and washer vibrating disc, a screening rail fixedly connected to the output end of the nut and washer vibrating disc, the screening rail being inclined downwards, a screening groove being formed on the screening rail, the screening groove having rounded corners near the edge of the nut and washer vibrating disc, a plurality of screening slots being formed at the bottom of the screening groove, an installation groove being formed on the front of the screening rail, the installation groove communicating with the interior of the screening slots, an adjusting plate being slidably installed in the installation groove, and a collection box being provided below the screening slots.

[0007] Preferably, support rods are symmetrically fixed to the underside of the screening track, and a base is fixed to the other end of each support rod. The collection box is placed on the base.

[0008] Preferably, the screening rail has graduations engraved on its front side and below the mounting groove.

[0009] Preferably, an L-shaped adjusting plate is fixedly connected to the front of the adjusting plate, and the end of the L-shaped adjusting plate extends out of the mounting groove.

[0010] Preferably, a threaded sleeve block is embedded in the front of the L-shaped adjusting plate, and a fixing bolt is installed in the internal thread of the threaded sleeve block. An anti-slip rubber pad is fixed to the front end of the fixing bolt.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. By placing the nut washers into the nut washer vibrating plate, the vibrating plate is started to arrange and convey the nut washers to the screening rail. The nut washers will slide into the screening trough and be in a vertical position. The nut washers will roll downwards and fall directly into the collection box after passing through the screening trough of the corresponding size, thus completing the sorting of the nut washers. Using the nut washer vibrating plate to arrange and convey the nut washers can minimize the direct friction and collision between the nut washers.

[0013] 2. The adjusting plate is slidably installed inside the installation groove. Moving the adjusting plate into the screening trough can block part of the screening trough space, thereby adjusting the size of the screening trough. The size of the internal space of the screening trough can be adjusted according to the size of the nut and washer to achieve the sorting of nut and washer of different sizes and specifications.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 This utility model provides a technical solution: a nut and washer sorting device, including a nut and washer vibrating plate 1, a screening rail 2 fixedly connected to the output end of the nut and washer vibrating plate 1, the screening rail 2 is inclined downwards, a screening roller groove 201 is opened on the screening rail 2, the corners of the screening roller groove 201 near the nut and washer vibrating plate 1 are rounded, a plurality of screening grooves 3 are opened at the bottom of the screening roller groove 201, an installation slide groove 301 is opened on the front of the screening rail 2, the installation slide groove 301 is connected to the interior of the screening grooves 3, an adjusting plate 4 is slidably installed in the installation slide groove 301, and a collection box 5 is provided below the screening grooves 3.

[0020] In this embodiment, the nut washers are placed inside the nut washer vibrating plate 1, which then arranges and conveys them to the screening rail 2. The connection between the screening rail 2 and the nut washer vibrating plate 1 is an arc-shaped inclined surface, allowing the nut washers to slide into the screening trough 201. During this sliding process, the nut washers change their orientation from lying flat to vertical. Since the screening rail 2 is inclined, the vertical nut washers roll downwards. Multiple screening grooves 3 are provided at the bottom of the screening trough 201. As the rolling nut washers pass through the screening grooves 3, they fall directly into the collection area. The nut washers are collected inside box 5. Adjusting plate 4 is slidably installed inside the mounting groove 301. Moving adjusting plate 4 inside the screening groove 3 can block part of the space in the screening groove 3, thereby adjusting the size of the screening groove 3. The internal space of the screening groove 3 is arranged from small to large to screen the nut washers. The device can automatically adjust the size of the internal space of the screening groove 3 according to the size of the nut washers to adapt to the screening of nut washers of different sizes. At the same time, the nut washer vibrating plate 1 is used to arrange and transport the nut washers, which can minimize the direct friction and collision between the nut washers.

[0021] In order to facilitate the adjustment of the extension distance of the adjustment plate 4, the device adopts the following technical solution: support rods 202 are symmetrically fixed to the bottom of the screening rail 2, and the other end of the support rod 202 is fixed to the base 203. The collection box 5 is placed on the base 203. The front of the screening rail 2 and below the mounting groove 301 are engraved with scale 302.

[0022] By cooperating with the support rod 202 and the base 203, the screening rail 2 can be effectively supported. The collection box 5 is placed on the base 203, while ensuring that each collection box 5 is below the screening trough 3. The nut washer passing through the screening trough 3 will fall directly into the collection box 5. By cooperating with the scale 302 and the L-shaped adjustment plate 401, the distance of the adjustment plate 4 can be accurately determined, which makes it convenient for the operator to adjust the size of the internal space of the screening trough 3.

[0023] In order to achieve the purpose of restricting the movement of the adjusting plate 4, the device adopts the following technical solution: an L-shaped adjusting plate 401 is fixedly connected to the front of the adjusting plate 4, the end of the L-shaped adjusting plate 401 extends into the mounting groove 301, a threaded sleeve block 402 is embedded in the front of the L-shaped adjusting plate 401, a fixing bolt 403 is installed in the internal thread of the threaded sleeve block 402, and an anti-slip rubber pad is fixedly connected to the front end of the fixing bolt 403.

[0024] Rotating the fixing bolt 403 can move the end anti-slip rubber pad, causing the anti-slip rubber pad to contact the outer wall of the screening rail 2. This, in turn, uses friction to restrict the movement of the L-shaped adjusting plate 401, fixing the position of the adjusting plate 4 and preventing the adjusting plate 4 from shifting due to vibration during use.

[0025] The working principle and usage process of this utility model are as follows: Based on the required size of the nut washers to be screened, the L-shaped adjusting plate 401 is moved to drive the adjusting plate 4 to move, adjusting the size of the space inside the screening trough 3. Then, the nut washers are placed inside the nut washer vibrating plate 1. The nut washer vibrating plate 1 is started to arrange and transport the nut washers to the screening rail 2. The nut washers will slide into the screening roller trough 201 and be in a vertical position. The nut washers will roll downwards, passing through the corresponding size screening trough 3 and falling directly into the collection box 5, thus completing the sorting of the nut washers.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
