Technical Field

[0001] This utility model relates to a feeding mechanism, and more particularly to a nut and washer vibrating screen feeding mechanism. Background Technology

[0002] The nut and washer vibrating screen is a device specifically designed for screening and processing fasteners such as nuts and washers. Its core function is to achieve efficient separation of materials and filtration of impurities through vibration.

[0003] For example, a nut and washer vibrating screen feeding mechanism, as disclosed in Chinese Patent Publication No. CN211359579U, includes a main body. Motors are installed on both the front and rear walls of the main body. A motor shaft is installed inside each motor. Vibrating rods are provided at both ends of the motor shaft. A vibrating shaft is provided at the left end of each vibrating rod. A vibrating wheel is provided around the vibrating shaft. A telescopic sleeve is provided on the lower inner wall of the main body. A telescopic column is provided directly above the telescopic sleeve. A spring connects the telescopic sleeve and the telescopic column. A locking block is provided on the upper surface of the telescopic column. A filling block is provided on the inner side wall of the main body near the upper end. This nut and washer vibrating screen feeding mechanism can vibrate and screen nuts and washers, filtering and collecting dust and impurities contained in the nuts and washers. This reduces waste of nuts and washers, increases their utilization rate, and provides convenient and quick feeding of nuts and washers, reducing the workload of workers.

[0004] Some problems were found when using the existing nut and washer vibrating screen feeding mechanism. First, the method of raising the screen plate and tilting the nut and washer for feeding will pour a large number of nut and washer onto the vibrating screen at one time, causing the nut and washer to accumulate together for screening, which affects the screening effect. Utility Model Content

[0005] The purpose of this utility model is to provide a nut and washer vibrating screen feeding mechanism 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 washer vibrating screen feeding mechanism, comprising a feeding hopper, a screen embedded in the bottom inclined surface of the feeding hopper, a guide plate inclinedly arranged inside the feeding hopper, a collection frame fixedly connected to the lower inclined surface of the feeding hopper, an installation opening on the front of the collection frame, a collection box slidably installed in the installation opening, a discharge port opened below the feeding hopper, limit blocks symmetrically fixed to the lower inclined surface of the feeding hopper, an adjusting plate sliding between the two limit blocks, a through groove opened in the discharge port, and the adjusting plate slidingly engaging with the through groove.

[0007] Preferably, the feeding hopper is symmetrically fixed with fixed feet on both sides, and a threaded adjusting rod is rotatably installed on the front of the feeding hopper and below the adjusting plate.

[0008] Preferably, a threaded sleeve is fixedly connected to the underside of the adjusting plate, and the threaded sleeve is threadedly engaged with the threaded adjusting rod.

[0009] Preferably, rotating shafts are fixedly connected to both sides of the guide plate, and the rotating shafts are rotatably connected to the feeding hopper.

[0010] Preferably, a conical roller is rotatably mounted inside the feeding hopper via a shaft, and a power motor is fixedly connected to one side of the feeding hopper, with the output end of the power motor fixedly connected to the conical roller.

[0011] Preferably, the collection frame has a threaded fixing hole on the front, the collection box has a handle fixedly connected to the front, and a fixing block is fixedly connected to the front of the collection box and on one side of the collection box. A fixing bolt is provided in the fixing block, and the fixing bolt is threadedly engaged with the threaded fixing hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. Rotating the threaded adjusting rod can move the threaded sleeve block, which in turn moves the adjusting plate. This adjusts the insertion depth of the adjusting plate within the discharge port and the size of the opening, limiting the discharge speed of the nut and washer. The nut and washer are then slowly and evenly lowered onto the vibrating screen, achieving uniform feeding and ensuring stable operation of the vibrating screen.

[0014] 2. The nut washer is guided to slide onto the inclined surface inside the hopper by the guide plate. The screen is embedded in the inclined surface inside the hopper. When the nut washer passes through the screen, the impurities and dust contained inside will be initially filtered, preventing too many impurities from adhering to the nut washer from entering the vibrating screen.

[0020] 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.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a nut washer vibrating screen feeding mechanism, including a feeding hopper 1, a screen 105 is embedded in the bottom inclined surface of the feeding hopper 1, a guide plate 2 is inclinedly arranged in the feeding hopper 1, a collection frame 4 is fixedly connected to the lower inclined surface of the feeding hopper 1, an installation port 401 is opened on the front of the collection frame 4, a collection box 403 is slidably installed in the installation port 401, a discharge port 102 is opened at the bottom of the feeding hopper 1, limit blocks 103 are symmetrically fixedly connected to the lower inclined surface of the feeding hopper 1, an adjusting plate 5 is slidably connected between the two limit blocks 103, a through groove is opened in the discharge port 102, and the adjusting plate 5 is slidably engaged with the through groove.

[0022] In this embodiment, the hopper 1 is installed as a whole on the nut washer vibrating screen, and then the nut washer is tilted into the hopper 1. The guide plate 2 is set at an inclination inside the hopper 1, which guides the nut washer to slide onto the inclined surface inside the hopper 1, so that the nut washer falls slowly down the inclined surface. When the nut washer passes through the screen 105, the impurities and dust contained inside are initially filtered, preventing too many impurities from entering the vibrating screen. The nut washer that slides to the bottom of the hopper 1 will be discharged through the discharge port 102. The rear end of the adjusting plate 5 will be inserted into the discharge port 102 through the opened groove to adjust the opening size of the discharge port 102, thereby limiting the discharge speed of the nut washer, and slowly and evenly dropping the nut washer onto the vibrating screen to achieve uniform feeding operation of the vibrating screen and ensure the stable operation of the vibrating screen.

[0023] In order to achieve the purpose of adjusting the feeding speed, the device adopts the following technical solution: fixed feet 101 are symmetrically fixed on both sides of the feeding hopper 1, and a threaded adjusting rod 104 is rotatably installed on the front of the feeding hopper 1 and below the adjusting plate 5. A threaded sleeve block 501 is fixedly connected below the adjusting plate 5, and the threaded sleeve block 501 is threadedly engaged with the threaded adjusting rod 104.

[0024] The feeding hopper 1 can be fixed on the vibrating screen by using the fixing foot 101 and bolts. The threaded adjusting rod 104 is threadedly engaged with the threaded sleeve block 501. Rotating the threaded adjusting rod 104 can drive the threaded sleeve block 501 to move. The movement of the threaded sleeve block 501 can drive the adjusting plate 5 to move. Adjusting the insertion depth of the adjusting plate 5 in the discharge port 102 and adjusting the size of the opening in the discharge port 102 can adjust the feeding speed as needed.

[0025] To achieve the purpose of collecting and screening impurities, the device adopts the following technical solution: a rotating shaft 201 is fixedly connected to both sides of the guide inclined plate 2, the rotating shaft 201 is rotatably connected to the feeding hopper 1, a conical roller 3 is rotatably installed in the feeding hopper 1 through the shaft, a power motor 301 is fixedly connected to one side of the feeding hopper 1, the output end of the power motor 301 is fixedly connected to the conical roller 3, a threaded fixing hole 402 is opened on the front of the collection frame 4, a handle 404 is fixedly connected to the front of the collection box 403, a fixing block 405 is fixedly connected to the front of the collection box 403 and located on one side of the collection box 403, a fixing bolt 406 is provided in the fixing block 405, and the fixing bolt 406 is threadedly engaged with the threaded fixing hole 402.

[0026] The guide plate 2 can be rotatably installed inside the feeding hopper 1 by rotating the shaft 201. In the event of blockage at the discharge port 102 at the bottom of the feeding hopper 1, the guide plate 2 can be flipped open to facilitate the operator in clearing the blockage. At the same time, starting the power motor 301 can drive the conical roller 3 to rotate. The conical roller 3 is conical in shape. The rotation of the conical roller 3 will cause the front end of the guide plate 2 to float up and down, assisting the nut washer on the guide plate 2 to fall. The collection box 403 is inserted into the collection frame 4 through the threaded fixing hole 402. Impurities and dust screened by the screen 105 will enter the collection frame 4 and be collected by the collection box 403. The handle 404 makes it easy to pull out the collection box 403. The fixing bolt 406 passes through the fixing block 405 and is then screwed into the threaded fixing hole 402 to fix the collection box 403 inside the collection frame 4, preventing the collection box 403 from being knocked out due to the high-frequency vibration of the vibrating screen.

[0027] The working principle and usage process of this utility model are as follows: When in use, the nut washer is directly poured into the inside of the feeding hopper 1. The guide plate 2 is set in an inclined position inside the feeding hopper 1, which will guide the nut washer to slide onto the inclined surface inside the feeding hopper 1. The power motor 301 is started to drive the conical roller 3 to rotate. The rotation of the conical roller 3 will cause the end of the guide plate 2 to float, which will help the nut washer on the guide plate 2 to fall slowly. When the nut washer passes through the screen 105, the impurities and dust contained inside will be initially filtered. The filtered impurities will enter the collection frame 4 and be collected inside the collection box 403. The nut washer that slides to the bottom of the feeding hopper 1 will be discharged through the discharge port 102. Rotating the thread adjustment rod 104 can drive the thread sleeve block 501 to move. The movement of the thread sleeve block 501 can drive the adjustment plate 5 to move. Adjusting the insertion depth of the adjustment plate 5 in the discharge port 102 and adjusting the size of the opening in the discharge port 102 can adjust the feeding speed as needed.

[0028] 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.
