The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

A rotary type debris retrieval apparatus is schematically shown in FIG. 1, and includes a housing 1 and a debris catching mechanism.

The inside of the box body 1 is provided with a partition plate 6, the inside of the box body 1 can be divided into an equipment cavity 2 and a recovery cavity 3 through the partition plate 6, the partition plate 6 is also provided with a channel hole 61, and the equipment cavity 2 can be communicated with the recovery cavity 3 through the channel hole 61. A fan 4 is arranged in the equipment cavity 2, and the fan 4 is used for increasing the gas flow speed in the device and plays a role in sucking the debris. When the fan 4 is activated, air inside the recovery cavity 3 will flow into the equipment cavity 2 through the passage hole 61.

Optionally, for the inside gas mobility of lifting means cavity 2 can set up exhaust hole 21 on the lateral wall of means cavity 2, can make things convenient for gas discharge means cavity 2 through exhaust hole 21, avoid the inside high-pressure condition that appears of this device.

The recycling cavity 3 is used for containing recycled chips, and a feeding pipe 5 is arranged on the side wall of the recycling cavity 3 far away from the partition plate 5. Air mixed with debris can be introduced inside the recovery cavity 3 through the feeding duct 5, which will be filtered and sieved on the debris intercepting means, so that the gaseous phase partially enters the equipment cavity 2, while the debris is trapped inside the recovery cavity 3. In addition, turbulence of the gas flow inside the recovery cavity 3 is avoided, the feed pipe 5 being opposite to the passage hole 61. When the feed pipe 5 is aligned with the passage hole 61, the gas phase portion can directly pass through the debris catching mechanism and directly enter the equipment cavity 2, increasing the gas flow velocity in the present apparatus.

Optionally, for the convenience of the staff taking out the recovered debris the side wall of the recovery cavity 3 may be provided with a discharge opening 31, correspondingly, for avoiding the discharge opening 31 to destroy the gas flow direction inside the recovery cavity 3, the discharge opening 31 should also include a discharge gate. When the device is used for debris recovery, the discharge gate is closed, so that gas is only introduced into the recovery cavity 3 through the feed pipe 5; when the apparatus is shut down, personnel may open the discharge gate and remove debris from the discharge opening 31.

The debris catching mechanism is provided between the feed pipe 5 and the passage hole 61, and its structure can be schematically shown in fig. 2. As shown in the drawing, the debris intercepting mechanism includes a rotating shaft 7, the rotating shaft 7 is disposed on the periphery side of the passage hole 61, and the rotating shaft 7 is rotatably connected to the partition plate 6. Optionally, a receiving hole is formed in the partition plate 4, one end of the rotating shaft 7 is inserted into the receiving hole, and the rotating shaft 7 is connected to the receiving hole through a bearing. The rotating shaft 7 is provided with fan blades 8 and a screen cover 9, and the screen cover 7 is used for shielding the passage hole 61 so that the debris is intercepted inside the recovery cavity 3.

Since the debris catching mechanism is disposed between the feed pipe 5 and the passage hole 61, the debris-laden air comes into contact with the debris catching mechanism after entering the recovery cavity 3, and the flow action of the air causes the fan blades 8 to rotate the rotating shaft 7 and the screen cover 9. While the debris catching mechanism is rotating, debris entrained in the air will be caught inside the recovery cavity 3 by the screen cover 9 and, due to the flow action of the gas, will accumulate on the screen cover 9 in the region coinciding with the passage hole 61. As the rotation progresses, the region where the accumulation of the chips occurs is misaligned with the passage hole 61, and the flow of the gas is hindered by the partition 6, so that the pressure against the chips becomes small. In this way, the debris accumulated on this area is separated from the screen cover 9, thereby preventing the screen cover 9 from being clogged.

Optionally, in order to avoid the fan blade 8 from blocking the falling of the debris, the distance from the fan blade 8 to the partition plate 6 should be smaller than the distance from the screen cover 9 to the partition plate 6. At this time, the air with the debris comes into direct contact with the screen cover 9, so that the debris can be easily separated from the screen cover 9 when the pressure of the air flow becomes small.

In actual operation, the relative position of the debris catching mechanism and the passage hole 61 will have an effect on the efficiency of the debris retrieval operation. Illustratively, when the rotary shaft 7 is disposed above the passage hole 61, the area of the screen cover 9 located above the rotary shaft 7 is subjected to a smaller pressure of the air flow, while the area of the screen cover 9 located below the rotary shaft 7 is subjected to a larger pressure of the air flow. When the debris in the upper area falls off, the debris moves downwards due to the action of gravity and passes through the lower area with higher air flow pressure again, so that some debris participates in two or more times of accumulation processes, and the working efficiency of the device is seriously influenced.

To avoid this, the rotating shaft 7 may be disposed below the passage hole 61, and at this time, the area of the screen cover 9 located above the rotating shaft 7 may receive a larger pressure of the air flow, while the area of the screen cover 9 located below the rotating shaft 7 may receive a smaller pressure of the air flow. When the region where the chippings are accumulated rotates to the position where the air pressure is small, the chippings can directly fall to the bottom of the recovery cavity, so that the efficiency of the chippings recovery can be improved, and the repeated accumulation condition is avoided.

Furthermore, in order to avoid that the debris introduced by the feeding pipe 5 enters the inside of the passage hole 61 from the edge position of the debris catching mechanism, optionally, the feeding pipe 5 should be inserted inside the recovery cavity 3, and there is a gap between the mouth of the feeding pipe 5 and the screen cover 9 that allows only the debris to pass through. When the gap between the mouth of the feed pipe 5 and the screen cover 9 is small, debris entering the recovery cavity 3 will come into direct contact with the screen cover 9 and therefore will not move towards the edge of the debris catching mechanism.

The operation of the above embodiment is explained as follows:

before the work is started, one end of the feeding pipe 5 is aligned to a chip generating position on the packaging production line, and the feeding pipe 5 is dredged, so that the phenomenon of pipeline blockage is avoided. Then, the fan 4 is started, and the chips enter the box body 1 by using the suction force generated by the fan 4, so that the chip recovery work is carried out. After the recycling operation has been carried out for a while, the packaging line and the fan 4 are shut off and the recycled chips are taken out through the discharge opening 31.

The following explains the effects of the above scheme:

the embodiment provides a rotating type debris recycling device, which can drive a screen cover to rotate through fan blades, so when an area where debris accumulation occurs rotates to a position where the pressure of air flow is low, the debris can be separated from the screen cover due to gravity. Through the process, the device can be kept smooth in the long-time working process, the shutdown and cleaning of the screen by workers are not needed, and the working efficiency of the scrap recovery work is improved.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
