The following is a brief description of the body components and principles of the material handling apparatus, and the specific parameters and materials selected may be adapted to different use environments. The overall structure of the material conveying device provided in this embodiment is shown in fig. 1. The material conveying device mainly comprises two communicated cabins: a material storage compartment 100 and a material transfer compartment 500. The material storage compartment 100 accommodates therein a material cartridge 200. In this patent, the magazine 200 is commonly used to load large pieces of metal material.

The material storage compartment 100 is provided with a top cover 110, and the top cover 110 can be opened, and then the material cartridge 200 is placed into the material storage compartment 100 main body. The top cover 110 is provided with two charging ports 111, and is provided with a charging port cover. The bulk metal material enters from the feed port 111 and drops into the material box 200. Sealing rings can be additionally arranged between the top cover 110 and the main body of the material storage cabin 100 and between the material inlet cover and the material inlet 111 so as to ensure strict air tightness. A guide rail (not shown) is provided in the material storage compartment 100, along which the material cartridge 200 can horizontally move. The material storage compartment 100 is provided with an air extraction hole and an air filling hole, and the two holes can share one hole.

The magazine 200 is a trough-shaped open container. The cassette floor 210 may be controlled to open or close. When the cartridge 200 is positioned within the cartridge bay 100, the cartridge floor 210 is closed and the cartridge 200 is ready to receive and hold metal material. When the material box 200 moves horizontally to the position of the material transfer compartment 500, the material box bottom plate 210 is opened, and the carried metal material drops off the material box 200, thereby completing the unloading. The openable bottom plate is adopted, so that the material box is a way of unloading. In other embodiments, other methods of unloading may be employed, such as: the material box is arranged in a form capable of being integrally turned.

The left side of the material storage compartment 100 has a left channel 120, and its further left side is fitted with a cylinder 300. The ram 310 may extend to the right and the ram 310 may be sufficiently elongated to ensure that the cartridge 200 is pushed into the material transfer module 500. The front end of the push rod 310 is provided with a connecting structure which can be connected with or separated from the material box 200, and the material box 200 is provided with a hole matched with the connecting structure. The connection structure at the front end of the push rod 310 is separated from the left side of the material cartridge 200 before the material cartridge 200 is pushed into the material transfer module 500 and is ready for further downward movement. Before the material box 200 moves horizontally leftwards, the connecting structure at the front end of the push rod 310 is connected with the corresponding position on the left side of the material box 200, and along with the movement of the air cylinder, the push rod 310 retracts leftwards to drive the material box 200 to return to the material storage cabin 100 so as to prepare for the next loading.

The sides of the material transfer module 500 communicate with the material storage module 100 through the right channel 130 of the material storage module 100. The material transfer module 500 is a chamber having a larger volume than the material storage module 100 and is open at its bottom and connected to a metal material melting device (not shown, such as a furnace) and has a discharge outlet 530, as shown in fig. 4. The material transfer module 500 and the right channel 130 are also provided with guide rails, and after the material box 200 moves horizontally to the material transfer module 500 along the guide rails, the material box bottom plate 210 is opened, and the metal material in the material box 200 falls into the material melting device. The right side of the material transfer module 500 is provided with a wall flange 510 having a cover plate that can be opened to allow maintenance of the internal components of the material transfer module 500. The front of the material transferring cabin 500 is provided with two observation windows 520 through which the working state of the material box 200 can be observed in real time, and problems can be handled in time, so that production accidents can be avoided.

The material transferring compartment 500 has a pushing mechanism above it, which is composed of a fixed frame 610, a motor 620, a coupling 630, a ball screw 640, a nut pair 650, a moving rod 660, a cover 670, etc. The bottom of the fixed frame 610 is fixed to the ceiling of the material transfer module 500.

The motor 620 is mounted on top of the fixed frame 610. The motor 620 rotates at a high speed but with a small torque, and the ball screw 640 requires a large torque to drive, but does not rotate at a high speed. In order to solve the above-mentioned contradiction, a coupling 630 is provided between the motor 620 and the ball screw 640, so that the rotation shaft of the motor 620 and the ball screw 640 are transferred via the coupling 630. The coupling 630 here serves mainly two purposes: (1) The rotation speed and torque output by the motor 620 to the ball screw 640 are changed, so that overload and burning of the motor 620 are prevented; (2) Isolating vibrations and reducing the impact of vibrations on the internal components and structure of motor 620. The coupling 630 can ensure reliability and service life of the motor 620. Preferably, the coupling 630 is a quincuncial coupling.

The nut pair 650 is sleeved on the ball screw 640, and the nut pair 650 can vertically move. The upper end of the moving rod 660 is fixed to the nut pair 650, and the lower end of the moving rod 660 passes through the top plate of the material transfer module 500 and is then fixedly connected to the cover plate 670. After the motor 620 rotates, the ball screw 640 is driven to rotate by the coupling 630, the nut pair 650 moves vertically upward or downward, and the moving rod 660 drives the cover 670 and the nut pair 650 to move in the same direction. The cover 670 is covered with an armoured insulation board 680 for insulation.

The cover plate 670 is provided with a connector 671 as shown in fig. 4. Which can be attached to or detached from the magazine 200. After the material box 200 moves to a predetermined position in the material transfer compartment 500, the cover 670 pushes the material box 200 downward again so as to be closer to the material melting device. After the material box 200 is completely unloaded, the cover plate 670 is connected with the material box 200, and then pulls the material box 200 to move upwards, so that the material box 200 is finally lifted to a height capable of horizontally moving.

A partition member is provided in the right passage 130, which is composed of a shutter 410 and a shutter valve 420. The shutter 410 is connected to the shutter valve 420, and the shutter 410 is driven to descend or ascend according to the operation of the shutter valve 420. When the shutter 410 is lowered into position, the right passageway 130 is completely closed, and the junction of the shutter 410 and the right passageway 130 remains well airtight. This ensures that the material storage compartment 100 is completely isolated from the material transfer compartment 500 and that gas cannot flow, which is a key feature of the material transfer apparatus provided by this patent. When the shutter 410 is fully raised, the right channel 130 is again penetrated, and the material cartridge 200 may be translated from the material storage compartment 100 to the material transfer compartment 500 via the right channel 130.

The workflow of the material conveying device comprises the following steps:

Step one: ensuring that the ram 410 has been lowered into place and sealed, the material storage compartment 100 is now completely isolated from the material transfer compartment 500, preventing outside air from entering the interior of the material melting apparatus and affecting process operation.

Step two: the charging port cover at the top of the material storage compartment 100 is opened to allow large-sized metal material to fall from the charging port 111, just filled into the material box 200, and then the charging port cover is closed. In order to make the metal material fall into the material box 200 uniformly, the material can be simultaneously discharged from the two charging ports 111.

Step three: after the metal material is filled, the interior of the material storage box 100 is evacuated and air is supplemented through the air pumping holes, so that the influence of air on the whole operation is reduced to the greatest extent.

Step four: the shutter 410 is raised and the material storage compartment 100 is now in communication with the material transfer compartment 500. The push rod 310 in the cylinder is moved from left to right by the pneumatic means to push the material box 200 horizontally along the slide rail into the material transfer compartment 500, and finally below the cover plate 670.

Step five: the motor 620 drives the ball screw 640 to rotate via the coupling 630, the nut pair 650 moves downward, and the moving rod 660 moves in the same direction as the nut pair 650 due to the fixed connection. The movable rod 660 is connected with the cover plate 670, and the cover plate 670 pushes the material box 200 below to move downwards to be close to the discharge hole 530.

Step six: the bottom plate 210 of the material box 200 is opened, and the metal material falls into the material melting device from the discharge port 530, thereby completing the discharging.

Step seven: after the unloading is completed, the motor 620 drives the ball screw 640 to rotate through the coupling 630, and the nut pair 650 is driven to move upwards. The moving rod 660 drives the cover plate 670 to move upwards, at this time, the cover plate 670 and the material box 200 are connected in advance, and the material box 200 rises along with the cover plate 670 and finally returns to the entrance of the right channel 130.

Step eight: the shutter 410 is raised so that the material storage compartment 100 is again in communication with the material transfer compartment 500 and is kept isolated from the outside air. The cylinder 300 moves the inner push rod 310 from right to left by pneumatic means. The push rod 310 is connected to the material box 200, and pulls the material box 200 back to the material storage compartment 100. The shutter 410 is again lowered to completely seal the material storage compartment 100 from the material transfer compartment 500. Thus, the material filling, conveying and discharging are finished for the next time, and preparation is made for the next cycle.

The foregoing describes in detail preferred embodiments of the present utility model. It should be understood that numerous modifications and variations can be made in accordance with the concepts of the utility model by one of ordinary skill in the art without undue burden. Therefore, all technical solutions which can be obtained by logic analysis, reasoning or limited experiments based on the prior art by the person skilled in the art according to the inventive concept shall be within the scope of protection defined by the claims.
