Abstract

Embodiments relate to the technical field of waste collection, in particular to waste collection equipment, which includes a temporary storage tank, a pressing tank and a pressing mechanism; the temporary storage tank is configured for receiving and temporarily storing wastes produced by die cutting equipment; the pressing tank is configured for carrying the wastes in the temporary storage tank; the pressing mechanism is configured for compressing the wastes in the pressing tank; the temporary storage tank is provided with a first blanking port, which is configured for communicating the temporary storage tank with the pressing tank; the first blanking port is provided with a first valve; and the first valve is configured for opening or closing the first blanking port to control whether the temporary storage tank discharges the wastes.

First claim

What is claimed is:

1. A waste collection equipment, comprising:
a temporary storage tank configured for receiving and temporarily storing wastes produced by die cutting equipment;
a pressing tank configured for carrying the wastes in the temporary storage tank; and
a pressing mechanism configured for compressing the wastes in the pressing tank; and,
wherein the temporary storage tank is provided with a first blanking port configured for communicating the temporary storage tank with the pressing tank, wherein the first blanking port is provided with a first valve, and the first valve is configured for opening or closing the first blanking port to control whether the temporary storage tank discharges the waste; and, wherein the waste collection equipment further comprises
a waste pipe, which is configured for making the wastes produced by the die cutting equipment flow into the temporary storage tank through the waste pipe; and
a gas pressure control device, configured for controlling a gas pressure in the temporary storage tank to be less than the gas pressure of a feed port of the waste pipe to change the speed at which the wastes flow into the temporary storage tank through the waste pipe, wherein the gas pressure control device is connected with a gas pressure pipe, the gas pressure pipe is at least partially located in the temporary storage tank, and a pipewall of the gas pressure pipe is provided with a gas pressure control port, and wherein the gas pressure control port is configured for enabling an inner cavity of the gas pressure pipe to be in gas communication with the temporary storage tank to control the gas pressure in the temporary storage tank.

2. The waste collection equipment according to claim 1 , wherein multiple penetrated first gas holes are arranged on a side wall of the temporary storage tank to receive external gas flow, so that the wastes fall off from the first blanking port.

3. The waste collection equipment according to claim 1 , wherein sections of the temporary storage tank along a horizontal direction narrow gradually from top to bottom, and the first blanking port is located on the smallest section of the temporary storage tank, to reduce remaining wastes in the temporary storage tank.

4. The waste collection equipment according to claim 1 , wherein a part of the gas pressure pipe located inside the temporary storage tank is located at an inner upper side of the temporary storage tank to prevent the wastes from blocking the gas pressure control port.

5. The waste collection equipment according to claim 1 , wherein an isolation plate is arranged inside the temporary storage tank and is configured for isolating the gas pressure control port from a discharge port of the waste pipe, and two sides of the isolation plate are in gas communication.

6. The waste collection equipment according to claim 1 , wherein the pressing tank comprises:
a blanking chamber, which is configured for receiving the wastes from the temporary storage tank through the first blanking port;
a pressing chamber, which is configured for receiving the wastes from the blanking chamber and defining a compression region for the wastes; and
a guide member, which is configured for guiding the wastes from the blanking chamber into the pressing chamber.

7. The waste collection equipment according to claim 6 , wherein second gas holes are formed in a side wall of the pressing chamber away from the blanking chamber; and the second gas holes are connected outside the pressing tank with a gas pressure control device to enable the wastes to fall to one side of the pressing chamber away from the blanking chamber.

8. The waste collection equipment according to claim 6 , wherein the pressing mechanism comprises a pressing plate, which is configured for compressing the wastes in the pressing chamber; the pressing plate is provided with third gas holes passing through two sides thereof, and the third gas holes are configured for discharging the gas between the wastes while the wastes are compressed.

9. The waste collection equipment according to claim 8 , wherein one side of the pressing plate in contact with the wastes has protruding support blocks, which are configured for pressing the wastes, and the support blocks are arranged in a manner of avoiding the third gas holes.

10. The waste collection equipment according to claim 9 , wherein the support blocks are non-metal blocks.

11. The waste collection equipment according to claim 1 , wherein the waste collection equipment further comprises a waste bin, which is configured for collecting the wastes in the pressing tank.

12. The waste collection equipment according to claim 11 , wherein a sealing assembly is arranged between a bottom wall of the pressing tank and the waste bin, and is configured for preventing the wastes from spilling out of the waste bin; and the sealing assembly comprises:
an upper sealing plate, which is connected to the bottom of the pressing tank;
a lower sealing plate, which is configured for pressing against an edge of an opening of the waste bin; and
a sealing cover, which is connected between the upper sealing plate and the lower sealing plate to realize sealing between the upper sealing plate and the lower sealing plate.

13. The waste collection equipment according to claim 12 , wherein the sealing assembly further comprises:
a driving member, which is configured for driving the lower sealing plate to move relative to the upper sealing plate, so that the lower sealing plate presses against or is separated from the edge of an opening of the waste bin.
