Description

Technical Field

[0001] The utility model belongs to the field of carbon material product production equipment, in particular to a full-automatic feeding device. Background Art

[0002] Graphite can be used as an anti-wear agent and lubricant. High-purity graphite is used as a neutron moderator in atomic reactors. It can also be used to manufacture crucibles, electrodes, brushes, dry batteries, graphite fibers, heat exchangers, coolers, arc furnaces, arc lamps, pencil refills, etc. In the existing technology, when processing graphite raw materials, a screw feeder is often used to transport the materials to the mold and maintain and press them into electrode plates. Since the graphite raw materials are in powder form, a lot of dust will be generated when the graphite raw materials are transported to the upper end and dropped from the discharge barrel. This dust is easy to fly in the air and easily cause pollution, endangering the health of employees. It also causes a lot of raw materials to be wasted, increasing production input costs.

[0003] CN110834957A discloses a graphite negative pressure feeding device, comprising a feed bin, a feed air duct, and a pulse dust collector. The feed bin is topped with a sieve plate; the feed air duct is horizontally positioned below the feed bin, with its sidewalls connected to the bottom of the bin; one end of the feed air duct is an air inlet, and the other end is connected to the pulse dust collector; the feed air duct is also equipped with a flow control valve; the pulse dust collector's air outlet is connected to an induced draft fan, a vertical spiral feeder is positioned within the pulse dust collector's hopper, and a horizontal spiral feeder is positioned at the bottom of the pulse dust collector's hopper. The outlet of the spiral feeder is connected to a graphite negative pressure feeding system. This graphite negative pressure feeding device utilizes a graphite negative pressure feeding system, which results in poor powder delivery continuity, a complex structure, and a large footprint.

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies and defects mentioned in the above background technology and to provide a fully automatic feeding device with good continuous conveying performance, simple structure and small space occupation.

[0005] In order to solve the above technical problems, the technical solution proposed by the present invention is: a fully automatic feeding device, comprising:

[0006] Equipment bracket, dust collector, negative pressure buffer bin, feeder, vibrating screen, metering bin, chute and feeding cart installed on the equipment bracket;

[0007] The dust collector is arranged at the upper end of the feed inlet of the negative pressure buffer bin and is used to remove the carbon powder dust at the feed inlet;

[0008] The feeder is connected to the bottom of the negative pressure buffer bin;

[0009] The vibrating screen is connected to the outlet of the feeder;

[0010] The metering bin is connected to the outlet of the rotary vibrating screen and can quantitatively transport carbon powder according to production needs;

[0011] The chute is fixed on the feeding trolley, and a receiving port is provided on the top of the chute and a feeding port is provided on the bottom. When conveying carbon powder, the feeding trolley controls the chute to move so that its receiving port is aligned with the outlet of the metering bin, and the feeding port of the chute is aligned with the feed port of the die-casting machine mold. After the conveying is completed, the feeding trolley controls the movement of the chute so that the chute leaves the feed port of the die-casting machine pressure head, so that the die-casting machine pressure head is aligned with the feed port of the die-casting machine mold for die-casting.

[0012] In one embodiment, the slide pipe is welded to one end of the feeding trolley, and the other end of the feeding trolley is connected to the driving device. A support plate is provided on the equipment bracket at the bottom of the feeding trolley, and the feeding trolley moves horizontally on the support plate.

[0013] In one embodiment, the slide pipe is welded to one end of the feeding trolley, and the slide pipe is fixed at an angle on the end of the feeding trolley, and the angle of the angle is 35°-42°.

[0017] In one embodiment, the feeder is connected to the rotary vibrating screen via a transverse pipe, and the rotary vibrating screen is located on one side of the bottom of the feeder.

[0018] In one embodiment, the receiving port of the chute is funnel-shaped, and the opening diameter of the receiving port is larger than the outlet diameter of the metering bin, and the feeding port of the chute is smaller than the feeding port of the die-casting machine.

[0019] Compared with the prior art, the present invention has the following beneficial effects: the fully automatic feeding device includes an equipment bracket, a dust collector mounted on the equipment bracket, a negative pressure buffer bin, a feeder, a vibrating screen, a metering bin, a chute, and a feeding cart. The negative pressure buffer bin uses the negative pressure within the bin to create an airflow at the feed port, drawing the carbon powder raw material into the bin. Because the carbon powder in the bin is easily drawn into the negative pressure air pump under negative pressure, potentially damaging the equipment, a dust collector is used to separate the negative pressure air pump from the carbon powder storage area within the bin and to treat carbon powder dust at the opening of the negative pressure buffer bin to prevent clogging. The metering bin accurately controls the carbon powder to enter the die-casting machine mold through the chute according to the amount of carbon powder required for the product to be produced; the chute is controlled to move by the feeding car. When the carbon powder is conveyed, the feeding car controls the chute to move until its receiving port is aligned with the outlet of the metering bin, and the feeding port of the chute is aligned with the feed port of the die-casting machine mold. After the conveying is completed, the feeding car controls the chute to move so that the chute leaves the feed port of the die-casting machine pressure head, so that the die-casting machine pressure head is aligned with the feed port of the die-casting machine mold for die-casting, thereby not hindering the operation of the die-casting machine and eliminating the need to move the die-casting machine equipment. The fully automatic feeding device of the present application has a simple structure, compact connection, small space occupation, and good powder conveying continuity.

[0021] Figure 1 It is a structural schematic diagram of a fully automatic loading device in one embodiment. DETAILED DESCRIPTION

[0022] In order to facilitate the understanding of the present invention, the present invention will be described in more comprehensive and detailed manner below in conjunction with the accompanying drawings and preferred embodiments of the specification, but the protection scope of the present invention is not limited to the following specific embodiments.

[0023] Unless otherwise defined, all technical terms used hereinafter have the same meanings as those generally understood by those skilled in the art. The technical terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the scope of protection of the present invention.

[0024] Unless otherwise specified, various raw materials, reagents, instruments and equipment used in the present invention can be purchased from the market or prepared by existing methods.

[0025] See also Figure 1The fully automatic loading device of one embodiment provided in the present application includes: an equipment bracket 10, a dust collector 20 arranged on the equipment bracket 10, a negative pressure buffer bin 30, a feeder 40, a rotary vibrating screen 50, a metering bin 60, a chute 70 and a feeding cart 80 and a driving device 90 for controlling the movement of the feeding cart 80. The dust collector 20 is arranged at the upper end of the feed port 32 of the negative pressure buffer bin 30, and is used to remove the carbon powder dust at the feed port; the feeder 40 is connected to the bottom of the negative pressure buffer bin 30; the rotary vibrating screen 50 is connected to the outlet of the feeder 40; the metering bin 60 is connected to the outlet of the rotary vibrating screen 50, and quantitatively conveys carbon powder according to production needs; the chute 70 is fixed on the feeding cart 80, and the top of the chute 70 is provided with a receiving port 72, and the bottom is provided with a feeding port 74; when conveying carbon powder, the feeding cart 80 controls the chute 70 to move so that its receiving port is aligned with the outlet of the metering bin, and the feeding port of the chute is aligned with the feed port of the die-casting machine mold 100. After the conveying is completed, the feeding cart 80 controls the chute 70 to move so that the chute 70 leaves the feed port of the die-casting machine pressure head, so that the die-casting machine pressure head is aligned with the feed port of the die-casting machine mold 100 for die-casting.

[0026] Specifically, in one embodiment, the equipment bracket 10 is a steel structure to ensure structural stability. Preferably, the dust collector 20 is a pulse dust collector. The negative pressure buffer bin 30 uses the negative pressure in the bin to form an airflow at the feeding port to suck the carbon powder raw material into the bin. Because of the negative pressure state, the carbon powder in the negative pressure buffer bin 30 can easily be sucked into the negative pressure air pump, causing damage to the equipment. The pulse dust collector adopts the pulse principle. The pulse dust collector can work intermittently. The pulse dust collector performs dust treatment, which can not only prevent carbon powder from clogging the negative pressure air pump, but also prevent the filter element of the dust collector 20 from being clogged, thereby extending the service life of the filter element.

[0027] Specifically, in one embodiment, the feeder 40 is a screw feeder. The screw feeder has high conveying efficiency, good stability during operation, is not prone to dangerous situations such as sudden failures, ensures the safety and continuity of the production process, and has good sealing to prevent the leakage of carbon powder raw materials from causing harm to the environment and operators. Preferably, the screw feeder is connected to the rotary vibrating screen 50 through a transverse pipe 42, and the rotary vibrating screen 50 is located on one side of the bottom of the feeder. The use of a screw feeder enables horizontal conveying of carbon powder, which increases the space utilization of the entire device. In order to make powder transportation more convenient and minimize the power device, the various components are roughly arranged from top to bottom, so the height of the entire device will be relatively high. The screw feeder is connected to the rotary vibrating screen 50 through a transverse pipe 42, and the rotary vibrating screen 50 is located on one side of the bottom of the feeder, which can reduce the installation height space requirement of the entire device.

[0028] Preferably, in one embodiment, the chute 70 is welded to one end of the feeder 80 to ensure docking accuracy. The other end of the feeder 80 is connected to the drive device 90, which is a pneumatic cylinder with a simple structure and easy operation. Specifically, the equipment bracket 10 is provided with a support plate at the bottom of the feeder 80, and the feeder 80 moves horizontally on the support plate. The chute 70 is fixed at an angle to the end of the feeder 80, and the angle is 35°-42°, which can ensure smooth unloading and no carbon powder residue.

[0029] Preferably, the receiving port of the chute 70 is funnel-shaped, and the diameter of the opening of the receiving port is larger than the diameter of the outlet of the metering bin 60, so that all the powder from the metering bin 60 can be received without spilling. The diameter of the feeding port of the chute 70 is smaller than the diameter of the feeding port of the die-casting machine, which can prevent carbon powder from spilling outside during feeding.

[0030] Compared with the prior art, the present invention has the following beneficial effects: the fully automatic feeding device includes an equipment bracket, a dust collector mounted on the equipment bracket, a negative pressure buffer bin, a feeder, a vibrating screen, a metering bin, a chute, and a feeding cart. The negative pressure buffer bin uses the negative pressure within the bin to create an airflow at the feed port, drawing the carbon powder raw material into the bin. Because the carbon powder in the bin is easily drawn into the negative pressure air pump under negative pressure, potentially damaging the equipment, a dust collector is used to separate the negative pressure air pump from the carbon powder storage area within the bin and to treat carbon powder dust at the opening of the negative pressure buffer bin to prevent clogging. The metering bin accurately controls the carbon powder to enter the die-casting machine mold through the chute according to the amount of carbon powder required for the product to be produced; the chute is controlled to move by the feeding car. When the carbon powder is conveyed, the feeding car controls the chute to move until its receiving port is aligned with the outlet of the metering bin, and the feeding port of the chute is aligned with the feed port of the die-casting machine mold. After the conveying is completed, the feeding car controls the chute to move so that the chute leaves the feed port of the die-casting machine pressure head, so that the die-casting machine pressure head is aligned with the feed port of the die-casting machine mold for die-casting, thereby not hindering the operation of the die-casting machine and eliminating the need to move the die-casting machine equipment. The fully automatic feeding device of the present application has a simple structure, compact connection, small space occupation, and good powder conveying continuity.
