Description

Technical Field

[0001] This utility model relates to the field of nut processing technology, and in particular to a screening device for nut processing that facilitates screening. Background Technology

[0002] Nuts are fasteners that are screwed onto bolts or screws to provide a fastening effect. They are a necessary component in all manufacturing machinery. Depending on the material, they are divided into several types, such as carbon steel, stainless steel, and non-ferrous metals. After the nuts are processed, defective ones need to be removed, so a nut processing screening device is required.

[0003] Existing equipment, such as CN220862040U, is a screening device for nut processing. It includes a base plate with fixed stacks at both ends of its top. Rollers are rotatably mounted on opposite sides of the fixed stacks, and belts are fitted onto the surfaces of the rollers. A conveyor motor is fixedly mounted on one side of each fixed stack, and the output end of the conveyor motor is fixedly connected to the rollers. Baffles are fixedly mounted on opposite sides of the fixed stacks. In daily use, after the nuts pass through the sieve plate, defective nuts fall through a circular groove and then through a storage cylinder onto the surface of the belt. Simultaneously, the conveyor motor is activated, and its output end drives the rollers to rotate, which in turn drives the belt, thus moving the nuts. The belt and conveyor motor automatically transport the nuts, preventing excessive accumulation that could affect the screening progress and efficiency.

[0004] The existing technology uses a filter screen to oscillate laterally to screen nuts. However, this process adds a large number of nuts at once, causing them to pile up and not disperse properly with the oscillation. This results in smaller nuts being "pressed down" by larger nuts and unable to pass through the corresponding screen holes. Larger nuts may also be unable to be "pushed" to the discharge port due to crowding, leading to a "mixing" phenomenon. This needs to be improved. Utility Model Content

[0005] The purpose of this invention is to solve the problem of insufficient nut screening in the existing technology, and to propose a convenient nut screening device for nut processing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a convenient screening device for nut processing, comprising a base plate, a support frame, a rotating shaft, and a screening device. The support frame is fixedly connected to the upper surface of the base plate, and the rotating shaft is rotatably connected to the inner wall of the support frame. There are two sets of the support frame and the rotating shaft, which are symmetrically arranged. The screening device is disposed between the two sets of rotating shafts. The screening device includes a mounting plate, which is fixedly connected to the side of the rotating shaft away from the support frame. A cylinder is slidably connected to the surface of the mounting plate, and bolts are slidably connected to the inner wall of the cylinder. The bolts are threadedly connected to the inner wall of the mounting plate. There are multiple sets of bolts arranged evenly around the circumference. The surface of the cylinder has multiple sets of drainage holes arranged evenly.

[0007] Furthermore, a motor is fixedly connected to the upper surface of the base plate, a drive wheel is fixedly connected to the output end of the motor, a driven wheel is fixedly connected to the end of the rotating shaft away from the mounting plate, and belts are fitted inside the drive wheel and the driven wheel.

[0008] Furthermore, the mounting plate is provided with a loading and unloading assembly, which includes a through hole. The through hole is formed on the mounting plate, and a baffle is slidably connected to the inner wall of the through hole.

[0009] Furthermore, the inner wall of the through hole is provided with a groove, and a fixing rod is fixedly connected to the inner wall of the groove. A protrusion is slidably connected to the surface of the fixing rod, and the protrusion is fixedly connected to the side of the baffle near the groove.

[0010] Furthermore, a sliding groove is provided on the inner wall of the through hole, and a limiting groove is provided on both sides of the baffle near the sliding groove. A limiting rod is slidably connected to the inner wall of the sliding groove, and the limiting rod is slidably connected to the inner wall of the limiting groove. A guide rod is fixedly connected to the inner wall of the sliding groove.

[0011] Furthermore, the guide rod is slidably connected to the inner wall of the limiting rod, and a spring is sleeved on the surface of the guide rod. The two ends of the spring are fixedly connected to the inner wall of the first slide groove and the limiting rod, respectively. The inner wall of the first slide groove is provided with a second slide groove, and a paddle is slidably connected to the inner wall of the second slide groove. The paddle is fixedly connected to the limiting rod.

[0012] Furthermore, a limit bolt is threadedly connected to the side of the baffle near the support frame, and a pull strap is slidably connected to the surface of the limit bolt.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this invention, a screening device is installed to facilitate rapid screening of nuts. During screening, a lever is moved, causing a limiting rod to slide on the guide rod surface. The limiting rod disengages from the limiting groove and compresses the spring. Then, a pull belt separates the baffle from the mounting plate. Nuts to be screened are added into the cylinder through the through-hole. After adding all nuts, the baffle is reinstalled, and the motor is started. The motor drives the shaft to rotate via the drive wheel, driven wheel, and belt. The shaft rotates the cylinder via the mounting plate and bolts. Nuts rotate inside the cylinder, and defective nuts slide out through the leakage holes. If different batches of nuts are to be replaced, simply loosen the bolts and replace the cylinder with one featuring a different sized leakage hole. By installing the screening device, a large number of nuts can be screened at once, significantly improving screening efficiency and shortening the production cycle, thus effectively enhancing the equipment's convenience.

[0029] The effect achieved by the above-mentioned components is: to provide a through hole 491, which facilitates the addition of nuts into the cylinder 42 and the removal of the screened nuts.

[0030] Specifically, a groove 493 is provided on the inner wall of the through hole 491, a fixing rod 494 is fixedly connected to the inner wall of the groove 493, a protrusion 495 is slidably connected to the surface of the fixing rod 494, and the protrusion 495 is fixedly connected to the side of the baffle 492 near the groove 493.

[0031] The effect achieved by the above components is that the groove 493 and the protrusion 495 are provided to facilitate the installation of the baffle 492.

[0032] Specifically, a sliding groove 496 is provided on the inner wall of the through hole 491, and a limiting groove 497 is provided on both sides of the baffle 492 near the sliding groove 496. A limiting rod 498 is slidably connected to the inner wall of the sliding groove 496, and the limiting rod 498 is slidably connected to the inner wall of the limiting groove 497.

When screening nuts, the paddle 4912 is turned, and the paddle 4912 slides on the surface of the guide rod 4910 with the limit rod 498. The limit rod 498 disengages from the limit groove 497 and squeezes the spring 499. Then, the baffle 492 is separated from the mounting plate 41 by the pull belt 4914. Nuts to be screened are added into the cylinder 42 through the through hole 491. After the nuts are added, the baffle 492 is reinstalled, and then the motor 48 is started. The motor 48 drives the rotating shaft 3 to rotate through the drive wheel 47, the driven wheel 45 and the belt 46. The rotating shaft 3 drives the cylinder 42 to rotate through the mounting plate 41 and the bolt 44. The nuts rotate with the cylinder 42 inside the cylinder 42. Unqualified nuts slide out of the cylinder 42 through the leakage hole 43. If different batches of nuts are to be replaced, it is only necessary to loosen the bolt 44 and replace the cylinder 42 with a leakage hole 43 of a different size.
