Technical Field
[0001] This utility model relates to the field of gasket production, and in particular to a screening machine for gasket packaging. Background Technology
[0002] A gasket, also known as a washer, is a component placed between a connected part and a nut. It is generally a flat metal ring used to protect the surface of the connected part from scratches by the nut and to distribute the pressure exerted by the nut on the connected part. After processing, gaskets are sieved to remove defective products before packaging. Due to their small size, gaskets are difficult to count, so weighing is generally used to determine the amount to be packed in a single box. However, removing a specified weight of gaskets requires multiple insertions and removals from the box to confirm the correct weight, which makes the packaging time-consuming and inefficient.
[0003] Therefore, it is necessary to improve such a structure to overcome the above-mentioned defects. Utility Model Content

The rotating plate 102 is rotatably disposed in the installation space 101a. The first guide plate 103 is obliquely fixedly disposed in the installation space 101a and is located above the rotating plate 102. A damping mechanism is also provided on the base 101. The device 30, the output end of the damping device 30 is fixedly connected to the rotating plate 102, the screening assembly 20 includes a fixed frame 201 and a enclosure 202, the fixed frame 201 includes a base plate 201a and a plurality of connecting columns 201b, the connecting columns 201b are fixedly connected to the enclosure 202, and a receiving plate 40, a first screening plate 50 and a second screening plate 60 are arranged obliquely from top to bottom inside the enclosure 202, the second screening plate 60 is located above the first guide plate 103, and a vibration motor 80 is also provided on the outer wall of the enclosure 202. The enclosure 202 has a rectangular frame cross-section and is vertically continuous. The main width of the rotating plate 102 is the same as the width of the installation space 101a, and the width of the rotating plate 102 is reduced at the end near the discharge port 101b to match the width of the discharge port 101b. The width of the first guide plate 103 is the same as the width of the installation space 101a. The receiving plate 40 may include two plates arranged in a figure-eight shape.
[0035] like Figure 1-7 As shown, this utility model proposes a sieving machine for gasket packaging. The damping device 30 includes a lower plate 301 and an upper plate 302.

The distance between the bottom surface of the first baffle 503 and the first main body 501 is the upper limit of the thickness of the product to be sieved, and the end of the first baffle 503 is located at the first support channel 502. The width of the first sieving plate 50 is smaller than the width of the installation space 101a.
[0039] like Figure 1-7 As shown, the present invention proposes a sieving machine for gasket packaging. The sieving assembly 20 further includes a second guide plate 70, which is obliquely fixed inside the enclosure 202 and is disposed between the first sieving plate 50 and the second sieving plate 60.
[0040] like Figure 1-7As shown, this utility model proposes a sieving machine for gasket packaging. The second sieving plate 60 includes a second main body 601, a second support channel 602, and a second stop bar 603. The second main body 601 and the second support channel 602 are connected.

The width of the second sieving plate 60 is the same as the width of the first sieving plate 50, and the inclination direction of the second sieving plate 60 is opposite to the inclination direction of the first sorting plate.
[0041] like Figure 1-7 As shown, this utility model proposes a sieving machine for gasket packaging. The starting end of the second guide plate 70 is located below the first support channel 502, and the ending end of the second guide plate 70 is located above the ending end of the second main body 601. The sieving assembly 20 may further include a third guide plate, which is located between the second sieving plate 60 and the first guide plate 103. The starting position of the third guide plate is located below the second support channel 602, so that the gaskets falling from the second support channel 602 can land in the middle of the first guide plate 103, thereby making the gaskets more evenly distributed.
[0042] like Figure 1-7 As shown, the present invention proposes a sieving machine for gasket packaging, wherein the enclosure 202 is provided with a waste outlet 202a, the position of which corresponds to the position of the end of the second screening plate 60.
[0043] The working principle of this utility model is as follows:
[0044] a) Pour the gaskets into the enclosure from above;
[0045] b) After passing through the receiving plate, the gasket reaches the first screening plate;
[0046] c) The gasket slides along the inclined first screening plate and encounters the first stop bar.
[0047] d) If the pad is too thick, it cannot pass through and will reach the second guide plate via the first branch, and then reach the rear half of the second screening plate via the second guide plate.
[0048] e) The remaining pads continue to slide along the first screening plate and reach the front half of the second screening plate;
[0049] f) The pad continues to move until it encounters the second stop. Pads that are too thin are not affected by the second stop and continue to slide to the rear half of the second screening plate.
[0050] g) The remaining gaskets of suitable thickness pass through the second branch and reach the third guide plate or directly reach the first guide plate;
[0051] h) It then passes through the first guide plate and reaches the rotating plate;
[0052] i) As the number of shims accumulated on the rotating plate gradually increases, the damping mechanism is compressed, causing the rotating plate to rotate gradually;
[0053] j) Once the specified weight is reached, the rotating plate moves the locking block to rotate, and the end of the rotating plate is connected to the discharge port, and the gasket falls out from the discharge port.
[0054] k) Once the shims have almost all fallen out, the force provided by the nitrogen spring is greater than the force of the torsion spring of the locking block, causing the rotating plate to rotate back to its initial position.
[0055] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
