As shown in fig. 1, 4 and 5, in the embodiment of the present invention, the waste collecting device includes a collecting cavity 107 formed on the base 100, and a dropping channel 115 corresponding to the processing through slot 103 is formed at the top of the collecting cavity 107, so that waste generated during the cloth cutting process of the cloth 300 enters and is collected in the collecting cavity 107 after passing through the processing through slot 103 and the dropping channel 115; the outlet at the bottom end of the collecting cavity 107 is blocked by a blocking plate 109, the position of the blocking plate 109 is adjusted by a first screw rod 110, the first screw rod 110 is connected with the blocking plate 109 in a threaded connection mode, a handle 112 is fixedly mounted at the end part of the first screw rod 110, a supporting block 111 is further arranged at the bottom of the base 100, and the blocking plate 109 is supported, penetrates and slides on the supporting block 111, so that the first screw rod 110 is rotated by the handle 112, the blocking plate 109 is driven to move to block or open the outlet of the collecting cavity 107 according to the rotating direction of the first screw rod 110, and when the collecting cavity 107 is opened, waste collected in the collecting cavity 107 can be discharged.

With continuing reference to fig. 1, fig. 4 and fig. 5, in the embodiment of the present invention, the base 100 further has an exhaust cavity 116, the exhaust cavity 116 is communicated with one side of the top of the collecting cavity 107, a filter screen 117 is disposed at the communication position, the filter screen 117 is further provided with a cleaning assembly, the cleaning assembly is driven by a cleaning motor 113, the cleaning motor 113 is installed in the exhaust cavity 116, the base 100 is further provided with an exhaust pump 108, an air inlet end of the exhaust pump 108 is connected with the exhaust cavity 116 through an exhaust passage 114, so that when the exhaust pump 108 is started, the gas in the exhaust cavity 116 is continuously exhausted, and a negative pressure is generated in the collecting cavity 107, so that the waste materials of the cloth-cutting process performed on the processing platen 102 are better collected in the collecting cavity 107, and the cleaning assembly is used for cleaning the filtering surface of the filter screen 117.

Specifically, as shown in fig. 4, 7 and 8, in the embodiment of the present invention, the cleaning assembly includes an elastic member coaxially rotatably disposed on the filter screen 117, and a cleaning brush 119 mounted at an end of the elastic member; the elastic element is coaxially connected with an output shaft of the cleaning motor 113, so that the cleaning motor 113 can be utilized to drive the elastic element to rotate, and the cleaning brush 119 is driven to clean the filtering surface of the filter screen 117.

Further, in the embodiment of the present invention, the elastic member includes a supporting cylinder 1181 coaxially and rotatably disposed on the filter screen 117, a supporting slider 1182 is slidably supported in the supporting cylinder 1181 through a first supporting spring 1184, a supporting rod 1183 is mounted on the supporting slider 1182, the cleaning brush 119 is mounted at an end of the supporting rod 1183, and the cleaning brush 119 abuts against the filtering surface of the filter screen 117 under the elastic supporting action of the first supporting spring 1184, so that the cleaning brush 119 is tightly attached to the filtering surface of the filter screen 117 through the elastic member, which improves the cleaning effect on the filtering surface of the filter screen 117 and prevents the filter screen 117 from being blocked.

The above embodiments are merely illustrative of a preferred embodiment, but not limiting. When the invention is implemented, appropriate replacement and/or modification can be carried out according to the requirements of users.
