Technical Field

[0001] The utility model relates to the technical field of discharging devices, and specifically, to a negative-pressure chip-sucking discharging device. Background Art

[0002] At present, aluminum products have been widely used in our lives. When producing aluminum products, the raw materials will be first cut and decomposed into aluminum chips by cutting equipment to facilitate shaping using the aluminum chips. After the aluminum chips are divided and collected for discharging, generally a negative-pressure fan is used to suck the aluminum chips into the discharging port for discharging, so as to prevent incomplete collection of the aluminum chips during discharging and collection.

[0003] The existing discharging devices have the following problems:

[0004] In the traditional discharging port device, the impeller is in a frequent rotation state, which is easily worn and damaged, resulting in problems such as equipment failures and increased downtime. Moreover, when the impeller is damaged and needs to be repaired or replaced, it increases the equipment maintenance cost and downtime, affects the production efficiency, and the damage or loose seal of the impeller may cause negative-pressure loss, affecting the normal discharging effect and operation stability of the discharger, and reducing the working efficiency of the system.

[0005] In view of the above problems, for this reason, we propose a negative-pressure chip-sucking discharging device. Summary of the Utility Model

[0013] 1. In the present utility model, a double-layer pneumatic discharge valve is designed at the discharge port to ensure the stability of the negative pressure in the pipeline system without loss. When discharging materials, the double-layer pneumatic discharge valve controls the upper cylinder to start, so that the first opening and closing sealing plate pushes the fixed shaft to rotate, and thus the pneumatic connecting rod sealing plate rotates accordingly, controlling the opening of the upper pneumatic connecting rod sealing plate, and controlling the lower cylinder to drive the second opening and closing sealing plate to close and seal, preventing air or aluminum chips from leaking from the second opening and closing sealing plate, and ensuring that the negative pressure at the discharge port does not leak.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts fall within the scope of protection of the present invention. Embodiment 1

[0023] As Figures 1 to 4 shown, this embodiment proposes a negative pressure chip suction discharging device, which includes a discharging device main body 1 and a pneumatic connecting rod sealing plate 4. A first discharging port 2 is opened at the top of the discharging device main body 1, and a pneumatic connecting rod sealing plate 4 is arranged at the bottom of the first discharging port 2. Support frames 8 are arranged at both the upper and lower ends on the left side of the discharging device main body 1. A cylinder 7 is arranged inside the support frame 8. The extending end of the upper cylinder 7 is connected to a first opening and closing sealing plate 5. A fixed shaft 12 is penetrated inside the left side of the first opening and closing sealing plate 5. The pneumatic connecting rod sealing plate 4 is fixedly connected to the fixed shaft 12. The upper fixed shaft 12 is fixedly connected to the first opening and closing sealing plate 5. The upper cylinder 7 is fixedly connected to the first opening and closing sealing plate 5. The cylinder 7 is movably pinned to the support frame 8. The support frame 8 is fixedly connected to the discharging device main body 1. The pneumatic connecting rod sealing plate 4 is fixedly connected to the fixed shaft 12.

[0024] In this embodiment, during discharging, the double-layer pneumatic discharging valve controls the upper cylinder 7 to start, so that the first opening and closing sealing plate 5 pushes the fixed shaft 12 to rotate, thereby driving the pneumatic connecting rod sealing plate 4 to rotate accordingly, and controlling the opening and closing of the upper pneumatic connecting rod sealing plate 4. Embodiment 2

[0025] As Figures 1 to 4As shown in the figure, based on the same concept as in the above-mentioned Embodiment 1, this embodiment also proposes that a second discharge port 3 is provided inside the main body 1 of the discharging device. A second pneumatic link sealing plate 4 is provided at the bottom of the second discharge port 3. The extended end of the lower cylinder 7 is connected to a second opening and closing sealing plate 6. A second fixed shaft 12 is inserted inside the left side of the second opening and closing sealing plate 6. A transparent observation port 10 is provided on the right side of the main body 1 of the discharging device. A turbine vibrator 9 is provided on the right side of the second discharge port 3. A PU sealing plate 11 is provided on the top of the main body 1 of the discharging device. The lower fixed shaft 12 is fixedly connected to the second opening and closing sealing plate 6. The lower cylinder 7 is fixedly connected to the second opening and closing sealing plate 6. The main body 1 of the discharging device is composed of a PU sealing plate 11. The turbine vibrator 9 is fixedly connected to the second discharge port 3.

[0026] In this embodiment, during discharging, the double-layer pneumatic discharge valve controls the lower cylinder 7 to start, so that the second opening and closing sealing plate 6 pushes the fixed shaft 12 to rotate, thereby causing the pneumatic link sealing plate 4 to rotate accordingly, and controlling the opening and closing of the lower pneumatic link sealing plate 4.

[0027] In summary, the working steps are as follows:

[0028] First, the aluminum chips are sucked to the discharge port by a negative pressure fan through the pipeline system. This process ensures the effective transportation of the aluminum chips from the cutting equipment to the discharge port. Among them, the negative pressure fan is not shown in the text.

[0029] Secondly, a double-layer pneumatic discharge valve is designed at the discharge port to ensure the stability of the negative pressure in the pipeline system without leakage. During discharging, the double-layer pneumatic discharge valve controls the upper cylinder 7 to start, so that the first opening and closing sealing plate 5 pushes the fixed shaft 12 to rotate, thereby causing the pneumatic link sealing plate 4 to rotate accordingly, controlling the opening of the upper pneumatic link sealing plate 4, and controlling the lower cylinder 7 to drive the second opening and closing sealing plate 6 to close and seal, preventing air or aluminum chips from leaking from the second opening and closing sealing plate 6, and ensuring that the negative pressure at the discharge port does not leak.

[0030] Finally, when discharging stops, the double-layer pneumatic discharge valve controls the upper cylinder 7 to drive the first opening and closing sealing plate 5 to close and seal, controls the lower cylinder 7 to start, so that the second opening and closing sealing plate 6 pushes the fixed shaft 12 to rotate, thereby causing the pneumatic link sealing plate 4 to rotate accordingly, controlling the opening of the lower pneumatic link sealing plate 4, and allowing the aluminum chips to be discharged smoothly. The whole system forms a cyclic sealing process. Through the operation of the pneumatic link sealing plate 4, the sealing performance of the discharge port during operation and stop is ensured, preventing the loss of negative pressure and ensuring the stable operation of the system.

[0031] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
