Beaters are symmetrically arranged inside the housing, and a waste collection box is movably installed below the beaters within the housing for periodic cleaning. Its working principle is as follows: the conveyor belt feeds the raw cotton to be opened into the device; flexible hooks on the beaters pick up and unfold the cotton bolls; two sets of counter-rotating beaters open the cotton bolls through the gaps; the beaters strike and tear the raw cotton, and impurities in the raw cotton fall into the waste collection box under their own gravity, thus collecting impurities from the raw cotton.

[0004] Because the waste box is a movable part, it is difficult to make the connection between the waste box and the outer shell of the beater flat and airtight. The gap between the shell and the waste box is relatively large, which can easily lead to the leakage of impurities. On the other hand, when the waste box is full of impurities, it is easy to become clogged, and the waste box needs to be cleaned regularly so that it can continue to collect impurities. However, cleaning the waste box requires the dual-axis flow fine cotton opener to be shut down, which is not only cumbersome and inconvenient, but also directly affects the cotton opening progress. Therefore, it is necessary to improve it. Summary of the Invention

[0005] The purpose of this utility model is to provide a waste suction box for a dual-axial flow fine cotton opener that reduces the gap between the shell and the waste box, prevents impurities from leaking out from the gap, and eliminates the need for regular cleaning of the waste box.

[0016] As attached Figure 1-4 As shown The impurity suction box for a dual-axial flow fine cotton opener includes a box body 1 and a support plate 2. The box body 1 is a hollow trapezoidal body with openings at the top and bottom. A guide groove 3 is fixedly installed at the bottom of the box body 1. The cross-section of the guide groove 3 is U-shaped. The top of the guide groove 3 is set corresponding to the lower opening of the box body 1. A retaining edge 16 is provided on the port of the box body 1. The retaining edge 16 is rectangular and made of rubber. In use, the retaining edge 16 can be flexibly connected to the outer shell of the beater to achieve a tight seal at the connection between the box body 1 and the outer shell of the beater.

[0017] The guide channel 3 is connected to the inside of the box body 1. Support plates 2 are fixedly installed at both ends of the guide channel 3. The top of the support plate 2 is fixedly connected to the box body 1. The bottom of the support plate 2 is provided with a bending part. Pulleys 4 are symmetrically arranged at the bottom of the bending part. When in use, the support plate 2 provides sufficient support to the box body 1 so that the box body 1 can be placed stably. The bottom pulleys 4 facilitate the movement of the box body 1 so that the box body 1 can be removed for subsequent maintenance of the dual-axis flow fine cotton opening machine.

[0018] A guide pipe 5 is provided on the support plate 2 at the position corresponding to the guide channel 3. The guide pipe 5 is a rectangular tube with an inclined port and a flange on the edge of the port. A suction pipe is provided at the position corresponding to the guide pipe 5. The suction pipe is connected to the negative pressure filter device. During operation, the suction pipe can be tightly connected with the guide pipe 5 to draw and collect impurities in the box 1 through the guide pipe 5. The port of the suction pipe is also inclined. The purpose of this design is to facilitate the connection between the suction pipe and the guide pipe 5.

[0019] An anti-clogging mechanism is provided inside the guide channel 3. The anti-clogging mechanism includes a drive motor 6, a mounting base 7, a reciprocating lead screw shaft 8, and a sliding shuttle 9. Mounting bases 7 are symmetrically arranged on the inner wall of the box 1. The reciprocating lead screw shaft 8 is movably mounted between the mounting bases 7 via bearings. Two threaded grooves with the same pitch but opposite directions are machined on the circumference of the reciprocating lead screw shaft 8. The two ends of the two threaded grooves are connected by transition curves. Mounting plates 13 are fixedly mounted on the mounting bases 7. Guide rods 10 are fixedly mounted between the mounting plates 13. A slider 11 is movably mounted on the reciprocating lead screw shaft 8. A sliding shuttle 9 is movably mounted inside the slider 11. One end of the sliding shuttle 9 is crescent-shaped, and the other end is cylindrical. The cylindrical end of the sliding shuttle 9 is movably connected to the slider 11, and the crescent-shaped end of the sliding shuttle 9 is embedded in the spiral groove of the reciprocating lead screw shaft 8 for sliding connection. The slider 11 is slidably connected to the guide rod 10, and the guide rod 10 provides limiting and guiding functions for the slider 11.

[0020] A drive motor 6 is fixedly mounted on the outside of the housing 1 corresponding to the reciprocating lead screw shaft 8 via a motor mounting base 7. The drive motor 6 is connected to the reciprocating lead screw shaft 8. During operation, the drive motor 6 drives the reciprocating lead screw shaft 8 to rotate in one direction. Since the surface of the reciprocating lead screw shaft 8 is machined with two threaded grooves of the same pitch but opposite directions, the two ends are connected by a transition curve. The sliding shuttle 9 is embedded in the spiral groove and forms a cooperation with the reciprocating lead screw shaft 8. When the slider 11 and the sliding shuttle 9 reach the end of the spiral groove, the transition curve guides the slider 11 and the sliding shuttle 9 to move in opposite directions, thereby realizing the reciprocating motion of the slider 11.

[0021] A scraper 12 is detachably installed below the slider 11. The upper half of the scraper 12 is made of hard material, and the lower half is made of rubber. The purpose of this design is to make it easy for the scraper 12 to stick to the bottom surface of the guide channel 3 when it scrapes back and forth, so as to clean the guide channel 3. The bottom end of the scraper 12 extends into the guide channel 3 and contacts the bottom surface of the guide channel 3. During operation, the scraper 12 can push and collect the impurities in the guide channel 3 to both ends of the guide channel 3, so as to facilitate subsequent suction.

[0022] Corrugated soft sleeves (not shown in the figure) are fitted on the guide rod 10 and reciprocating screw shaft 8 between the mounting plate 13 and the mounting base 7 and the slider 11, respectively, to provide dust protection for the guide rod 10 and reciprocating screw shaft 8. The corrugated soft sleeves are commercially available parts. During operation, the corrugated soft sleeves provide dust protection for the guide rod 10 and reciprocating screw shaft 8. When the corrugated soft sleeves are squeezed or stretched, they can slide in conjunction with the slider 11 while providing dust protection.

[0023] The box body 1 is equipped with a pull handle 14. The pull handle 14 has a cross-section in the shape of "𠃍". During operation, the pull handle 14 makes it easy for the staff to drag the box body 1 to move, which facilitates later maintenance.

[0024] The box body 1 has a window, and a transparent glass window 15 for observation and maintenance is installed on the window by bolts for detachable sealing. During operation, the transparent glass window 15 allows the staff to easily observe the accumulation of impurities inside the box body 1, and also makes it easy for the staff to replace the worn scraper blade 12.

[0025] When the impurity suction box used in the dual-axial flow fine cotton opening machine is working, the impurities in the raw cotton first fall from the manual opening position into the box body 1, slide down the box body into the guide groove 3, and then the operator starts the drive motor 6, which drives the reciprocating screw shaft 8 to rotate in one direction, realizing the reciprocating motion of the slider 11. During the reciprocating motion of the slider 11, the scraper 12 reciprocates synchronously. When the scraper 12 reciprocates, the rubber bottom of the scraper 12 contacts the bottom surface of the guide groove 3, thereby pushing the impurities to both ends of the guide groove 3. This makes it convenient for the suction pipe to suck up and collect the impurities at both ends of the guide groove 3 through the guide pipe 5, reducing the problem of impurities remaining and accumulating in the middle area of ​​the guide groove 3. In this way, there is no need to clean the impurity box regularly, which solves the problem of the poor convenience of the existing manual cleaning of the impurity box and the need to shut down the cotton opening machine, which affects the working progress of the cotton opening machine.

[0026] The waste removal box used in the dual-axial flow fine cotton opening machine effectively reduces the gap between the shell and the waste removal box through the baffle 16, preventing impurities from leaking out from the gap.
