Description

Technical Field

[0001] This utility model relates to the field of vibratory feeder technology, and in particular to a vibratory feeder scraper airflow composite cleaning device. Background Technology

[0002] In the field of industrial automation production, vibratory feeders are widely used automatic feeding devices that can orient and transport disordered materials according to specific sorting rules, playing a key role in many industries such as electronics, hardware, and food. With prolonged use, material residue can accumulate at the discharge port and on the inner wall of the vibratory feeder, affecting not only the normal operating efficiency of the equipment but also potentially leading to material contamination and a decline in product quality. Therefore, timely and effective cleaning is crucial to ensuring the stable operation of the vibratory feeder.

[0003] Currently, the cleaning technologies for vibratory feeders mainly include manual wiping, simple airflow blowing, and single-blade scraping. Manual wiping requires machine shutdown, consuming significant manpower and time costs, and is inefficient and labor-intensive. While simple airflow blowing achieves non-contact cleaning, it struggles to achieve ideal cleaning results for stubborn, highly adhesive materials, easily creating cleaning blind spots. Single-blade scraping only addresses visible material residue on the vibratory feeder surface, failing to effectively remove material from hard-to-reach corners or crevices. Furthermore, the lack of pretreatment for loose materials causes significant resistance during scraper operation, accelerating blade wear and reducing scraper lifespan. In addition, existing cleaning devices have limited functionality, failing to flexibly select cleaning methods based on actual cleaning needs, making it difficult to achieve efficient and comprehensive cleaning results.

[0004] Therefore, developing a new type of cleaning device that can solve existing technical problems such as cleaning difficulties, cleaning dead spots, and limited functionality of cleaning devices is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] To address the problems existing in the background technology, this utility model develops a scraper-airflow composite cleaning device for vibratory feeders to meet the demand for efficient cleaning of vibratory feeders in industrial production. This device mainly includes a vibratory feeder, with an air jet unit at the top and a scraper unit at the center of the feeder's interior.

[0006] The jet section uses high-pressure gas to perform preliminary cleaning of the inside of the vibratory plate, removing larger dirt or residual material. Then, the scraper section is activated to further clean the feed plate guide rail inside the vibratory plate.

[0007] Furthermore, the jet section includes an annular air pipe with two fixing blocks symmetrically arranged on it. The fixing blocks are used to fix the annular air pipe above the vibrating plate. An air inlet is connected to the outside of one of the fixing blocks. At least six jet nozzles are evenly distributed on the annular air pipe, and the jet nozzles face the inside of the vibrating plate.

[0008] In use, high-pressure gas enters the annular air pipe through the air inlet, and then is sprayed into the vibratory plate through the air jets evenly distributed on the annular air pipe, so as to achieve preliminary cleaning of the inside of the vibratory plate.

[0009] Furthermore, the jet nozzle is a vector nozzle, and the angle of the jet nozzle is adjusted on the annular air pipe via a circular universal joint.

[0010] Furthermore, a venturi tube is provided at the air inlet.

[0011] The jet nozzle is an adjustable-angle vector nozzle, which can be finely adjusted according to different types of vibratory discs to achieve jet cleaning in some dead corners. A venturi tube is provided at the air inlet to further increase the gas flow rate of the jet section.

[0012] Furthermore, the scraper section includes a support rod, which is vertically disposed in the middle of the vibratory feeder. A guide rod is sleeved above the support rod, and the guide rod can move up and down along the support rod. A turntable is disposed above the guide rod, and the turntable can rotate around the guide rod. A scraper rod is disposed extending outward from the turntable, and a scraper is disposed at the front end of the scraper rod. The scraper is disposed at the feed plate guide rail of the vibratory feeder. A first motor is disposed inside the turntable, and the first motor drives the turntable to drive the scraper to rotate in a circular motion.

[0013] The scraper is mounted on the feed plate guide rail of the vibratory feeder via the scraper rod. The first motor drives the scraper to make a circular motion along the feed plate guide rail. Since the feed plate guide rail is spirally upward, the scraper will move upward along the feed plate guide rail during the movement. The guide rod can move upward along the support rod to realize the upward movement requirement of the scraper.

[0014] Furthermore, the scraper bar is composed of at least three curved sections, which are telescopically connected to each other.

[0015] The scraper rod is composed of at least three telescopic curved sections, and its overall length can be adjusted to accommodate different vibratory feeders.

[0016] Preferably, a support rod is provided below the scraper rod, one end of which is connected to the turntable, and the other end is located below the scraper rod. The support rod is used to support the scraper rod.

[0017] The support rod is used to support the scraper rod to prevent it from breaking due to insufficient strength because it is too long.

[0018] Furthermore, a worm gear is provided on the guide rod, and the scraper part also includes a worm wheel, which meshes with the worm gear. A second motor is connected to the rear of the worm wheel, and the second motor drives the worm wheel to rotate.

[0019] The second motor drives the worm gear to rotate, which in turn drives the worm of the guide rod to move up and down, cooperating with the first motor to achieve the spiral upward and downward movement of the scraper.

[0020] Preferably, the scraper is made of polytetrafluoroethylene.

[0021] Polytetrafluoroethylene (PTFE) has an extremely low coefficient of friction, allowing it to slide easily without damaging the surface of the discharge guide rail, providing excellent protection for the rail. It exhibits excellent chemical stability, reacting almost entirely with no chemicals and possessing strong corrosion resistance. Its good flexibility allows it to adapt to guide rails of various shapes, preventing breakage and minimizing scratches on the discharge guide rail surface.

[0022] The advantages and beneficial effects of this utility model are as follows: This utility model combines an air jet unit and a scraper unit through a composite cleaning structure, achieving efficient and thorough cleaning of the vibratory feeder. The air jet unit sprays high-pressure gas through evenly distributed air nozzles on the annular air pipe, performing preliminary cleaning of the inside of the vibratory feeder, effectively removing larger dirt and residual materials, solving the problem that simple airflow purging in the prior art is insufficient for handling stubborn materials, and completing the pretreatment of loose materials. The scraper unit, driven by a motor, moves the scraper in a circular motion along the spiral feeding plate guide rail and rises synchronously, enabling deep cleaning of the guide rail, handling stubborn residues, and overcoming the shortcomings of the single scraper scraping method in terms of cleaning dead angles.

[0029] like Figures 1 to 4 As shown, the automatic cleaning vibratory feeder of the present invention mainly includes a vibratory feeder 1, an air jet unit 2 disposed on the top of the vibratory feeder 1, and a scraper unit 3 located at the center inside the vibratory feeder 1. Through the coordinated operation of the air jet unit 2 and the scraper unit 3, efficient cleaning of the vibratory feeder is achieved.

[0030] In this embodiment, the annular air pipe 21 of the jet section 2 has a circular structure. Two fixing blocks 22 are symmetrically arranged on its outer circumference. The fixing blocks 22 are used to securely install the annular air pipe 21 above the vibrating plate 1 through bolts or other connecting parts. An air inlet 23 is provided on the outer side of one of the fixing blocks 22.

[0031] Eight jet nozzles 24 are evenly distributed on the annular air pipe 21, all facing the interior of the vibrating plate 1. The jet nozzles 24 are vector nozzles, connected to the annular air pipe 21 via a circular universal joint, allowing for angle adjustment within a certain range. Simultaneously, a venturi tube is installed at the air inlet 23 to increase the gas flow rate.

[0032] The support rod 31 of the scraper section 3 is vertically arranged in the middle of the vibratory plate 1, and a guide rod 32 is sleeved on the support rod 31. The guide rod 32 and the support rod 31 are connected by a linear bearing, so that the guide rod 32 can move up and down along the support rod 31.

[0033] A turntable 33 is mounted on the top of the guide rod 32 via a bearing, and a first motor 331 is installed inside the turntable 33. The output shaft of the first motor 331 is fixedly connected to the turntable 33, which can drive the turntable 33 to rotate. A scraper rod 34 is provided extending outward from the edge of the turntable 33. The scraper rod 34 is composed of three curved rods 341 connected by a telescopic sleeve structure, which can adjust the length. A scraper 35 is installed at the front end of the scraper rod 34. The scraper 35 is made of polytetrafluoroethylene and is located at the feed plate guide rail of the vibratory feeder 1. Below the scraper rod 34, a support rod 342 is provided, with one end hinged to the turntable 33 and the other end supported in the middle of the scraper rod 34.

[0034] A worm gear 321 is machined on the side of the guide rod 32, and a worm wheel 322 meshes with the worm gear 321. The rear of the worm wheel 322 is connected to a second motor 323, which is fixed to the support rod 31 by a bracket.

[0035] How to use:

[0036] When cleaning the vibratory feeder 1 is required, the jet unit 2 is activated first. A high-pressure gas source is connected to a venturi tube via an inlet 23. The gas is accelerated through the venturi tube and enters the annular air pipe 21, then is sprayed into the vibratory feeder 1 through the jet nozzle 24 on the annular air pipe 21. Depending on the specific structure and level of dirt on the vibratory feeder 1, the angle of the jet nozzle 24 is adjusted by changing the circular universal joint to perform a preliminary cleaning of the inside of the vibratory feeder 1, removing loose materials and dirt.

[0037] After initial purging, the scraper unit 3 is activated. The second motor 323 drives the worm gear 322 to rotate, and through the meshing transmission between the worm gear 322 and the worm 321, the guide rod 32 spirals upward. The first motor 331 drives the turntable 33 to rotate, which in turn drives the scraper rod 34 and scraper 35 to move in a circular motion along the feed plate guide rail of the vibratory plate 1. Because the feed plate guide rail is spirally upward, the scraper 35 moves upward synchronously during the circular motion, scraping and cleaning stubborn residual material on the guide rail surface. During the cleaning process, the length of the scraper rod 34 can be adjusted according to the size of the vibratory plate 1 to ensure full contact between the scraper 35 and the guide rail. Simultaneously, the support rod 342 provides support for the scraper rod 34, ensuring its stability. If only a single cleaning method is required, the jet unit 2 or the scraper unit 3 can be activated separately to flexibly meet different cleaning needs.

[0038] The above provides a detailed description of the vibratory feeder scraper airflow composite cleaning device provided by this utility model. Specific examples have been used to illustrate the principle and implementation of this invention. It should be noted that those skilled in the art can make various improvements and modifications to this invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
