A pair of first handles 175 are fixedly installed on the front side wall of the adjustment boxes 174.

[0033] As a further embodiment of the present invention, the interception structure 2 includes a first support 21, an interception box 22, two pairs of flipping frames 23, a collection box 24, a first transfer pipe 25, and a pair of interception components 26; one end of the first support 21 is fixedly mounted on the upper wall of the base 11 and located to the left of the controller 13; the interception box 22 is a rectangular box without an upper or lower wall, and a partition is fixedly mounted in the middle of its interior; the interception box 22 is fixedly mounted on the other end of the first support 21; and guide holes are provided on both the left and right side walls of the interception box 22, which are symmetrically located on the front and rear sides of the partition; one end of each pair of flipping frames 23 is symmetrical.

Two ends of the first adapter pipe 25 are connected to the guide hole on the right side wall of the interception box 22, and the other end of the first adapter pipe 25 is connected to the extraction port of the buckle box 171. A pair of interception components 26 are fixedly mounted on the interception box 22 and are symmetrically located on the front and rear sides of the partition. The interception components 26 can form two corresponding cavities inside the interception box 22 supported by the first bracket 21 to collect fibers separately.

[0034] As a further embodiment of the present invention, the interception assembly 26 includes a support 261, a hydraulic cylinder 262, an interception box 263, a transmission frame 264, a base plate 265, and a transmission rod 266.

The interception box 263 is movably inserted into the interception box 22. One end of the transmission frame 264 is fixedly disposed on the upper wall of the interception box 263, and the other end of the transmission frame 264 is located on the front side of the interception box 22. The base plate 265... One end is movably positioned between the other ends of one pair of flipping frames 23, and the other end of the base plate 265 can be attached to the lower wall of the partition to seal the bottom of the interception box 22. One end of the transmission rod 266 is fixedly positioned in the middle of one end of the base plate 265, and the other end of the transmission rod 266 is movably connected to the other end of the transmission frame 264. The extension drive of the hydraulic cylinder 262 can drive the interception box 263 to rise through the transmission frame 264, and when the conveying hole and the guide hole are staggered to be fully aligned, the interception box 263 is closed and no more fibers can enter. Furthermore, the upward pull of the transmission frame 264 drives the base plate 265 to flip and open the bottom of the interception box 263 for feeding.

[0035] As a further embodiment of the present invention, the adsorption structure 3 includes a filter box 31, a filter screen 32, a second support 33, a vacuum pump 34, and a second adapter pipe 35. The filter box 31 is fixedly disposed in the middle of the left side wall of the interception box 22, and both the left and right side walls of the filter box 31 are provided with interfaces corresponding to the material guide holes. The interface on the right side wall of the filter box 31 is connected to the material guide hole on the left side wall of the interception box 22. The filter screen 32 is inserted into the filter box 31. One end of the second support 33 is fixedly disposed on the upper left side wall of the base 11, and the vacuum pump 34 is fixedly disposed on the other end of the second support 33. The second adapter pipe 35 is a three-way pipe structure. One end of the second adapter pipe 35 is fixedly connected to the air inlet end of the vacuum pump 34, and the other two ends of the second adapter pipe 35 are respectively fixedly connected to the interface on the left side wall of the filter box 31. The material guide hole on the left side of the interception box 22 is blocked by the filter box 31 and the filter screen 32, so that the adsorbed fibers cannot pass through the interception box 263. The vacuum pump 34 generates suction to achieve extraction and transportation.

[0036] As a further embodiment of the present invention, the interception box 263 can be moved up and down alternately by means of the hydraulic cylinder 262, and the alternating movement can help to continuously convey.

[0037] As a further embodiment of the present invention, when the interception box 263 is raised, the bottom plate 265 flips down to open the bottom of the interception box 22 for interception and subsequent delivery.

[0038] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0039] The equipment can be moved by the casters 12 under the base 11 in the hoisting structure 1, bringing it closer to the discharge position of the cutting equipment. Then, the controller 13 controls the electric slide rail 14 to move up and down, which in turn drives the clamping assembly 17 to adjust its height so that the clamping assembly 17 is aligned with the discharge position. At the same time, since the two ends of the connecting plate are movably connected to the bearing arm 15 and the adapter rod 172 on the clamping box 171, the clamping assembly 17 can also be adjusted to a certain height and tilt angle with the help of the connecting arm 16 to improve the overall alignment applicability.

[0040] Then, it can be driven by the air pump 34 on the second support 33 in the adsorption structure 3, which is connected to the interception box 22 through the second adapter pipe 35. The interception box 22 is connected to the clamping assembly 17 through the first adapter pipe 25, which can generate suction and use the clamping assembly 17 as the inlet to adsorb, extract and transport the cut fibers.

[0041] In use, the clamping assembly 17 can extend and retract within the clamping box 171 by applying force through the first handle 175, thereby adjusting the adsorption space of the clamping box 171 and fixing it with the fastening bolts 173. This allows for corresponding adjustments based on the discharge port range of the cutting equipment.

[0042] The cut-off limit is then inserted into the interception box 263 in the interception assembly 26 through the clamping assembly 17; since the suction end of the air pump 34 is blocked by the filter screen 32 in the filter box 31, the fiber cannot pass through the interception box 22 supported by the first bracket 21, and thus it is stopped in the interception box 263.

[0043] At this time, the interception box 263 is completely embedded in the interception box 22, and the bottom plate 265 of the corresponding interception box 263 is horizontally fastened to the bottom cover; when the hydraulic cylinder 262 on the control support 261 is extended and driven, the interception box 263 will be driven to rise from the interception box 22 through the transmission frame 264. The rise of the interception box 263 will cause the conveying hole on the side wall of the interception box 263 to move alternately with the corresponding guide hole on the interception box 22. In the end, the conveying hole will be sealed by the side wall of the interception box 22, and the guide hole will also be sealed by the side wall of the interception box 263. Thus, the two sets of interception components 26 can be used alternately without stopping the air pump 34.

[0044] As the transmission frame 264 rises, the transmission rod 266 drives the bottom plate 265 to flip downward between the flipping frame 23, thereby opening the bottom of the interception box 22 and allowing the fibers intercepted in the interception box 263 to fall into the collection box 24 or the corresponding collection bag for transportation.

[0045] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
