[0021] See also Figure 1-5 The utility model provides an embodiment: a lower dust collecting device for a jet loom and a jet loom, a lower dust collecting device for a jet loom, comprising a supporting device 2, the supporting device 2 comprising a filter screen 9 and a connecting air chamber 10, the filter screen 9 is fixedly installed inside the top end of the connecting air chamber 10.

[0022] A T-shaped key slot is provided at the top of the front end of the connecting air chamber 10, which can ensure that the displacement sliding key 6 moves in a straight line inside the T-shaped key slot.

[0023] A jet loom comprises a displacement device 1 and a positioning component 3. The displacement device 1 is threadedly sleeved inside the positioning component 3. The displacement device 1 comprises a guide block 4, a special-shaped base frame 5, a displacement slide key 6, a nylon brush handle 7 and a special-shaped bracket 8. The guide block 4 is fixedly mounted on the top of one end of the special-shaped base frame 5. The displacement slide key 6 is symmetrically fixedly mounted on the bottom of the other end of the special-shaped base frame 5 away from the guide block 4. The special-shaped bracket 8 is fixedly mounted on both sides of the special-shaped base frame 5. The nylon brush handle 7 is fixedly mounted on the bottom of the special-shaped bracket 8. A thread is opened through the inner center of the guide block 4, so that the threaded rod 14 can be easily installed in alignment with the guide block 4.

[0024] The positioning component 3 includes a positioning device 11, an air jet loom 12, a driving motor 13 and a threaded rod 14. The driving motor 13 is fixedly installed at the inner bottom end of the air jet loom 12, and the threaded rod 14 is fixedly installed at the side end center of the driving motor 13. The positioning device 11 is fixedly installed at both ends of the bottom of the air jet loom 12. The positioning device 11 includes a special-shaped groove 15, a sealed plate 16 and a collecting cavity 17. The special-shaped groove 15 is opened on the side end of the collecting cavity 17, and the sealed plate 16 is hingedly installed on the inner top end of the collecting cavity 17, which can support the driving motor 13 to work.

[0025] The collecting chamber 17 is fixedly mounted at both ends of the bottom of the air jet loom 12, and the guide block 4 is threadedly sleeved on the threaded rod 14. When the threaded rod 14 rotates, the guide block 4 can be driven to move.

[0026] The connecting air chamber 10 is fixedly installed between the two collecting chambers 17. The interior of the collecting chamber 17 is hollow, and the special-shaped groove 15 is horizontally aligned with the nylon brush handle 7 and the special-shaped bracket 8, so that the nylon brush handle 7 and the special-shaped bracket 8 can push the debris into the interior of the collecting chamber 17.

[0027] Working principle: When in use, the air chamber 10 can be connected to an external vacuum cleaner, and then the air jet loom 12 can be turned on. When the air jet loom 12 is transmitting the cloth, the external vacuum cleaner can be started. The air chamber 10 is located below the inside of the air jet loom 12, so that the absorption work can be carried out from the bottom of the air jet loom 12, so that the broken lint dropped from the cloth can be absorbed in time. At the same time, the filter screen 9 can prevent foreign objects from entering the inside of the vacuum cleaner. Afterwards, when too much broken lint accumulates on the surface of the filter screen 9, it will affect the passing effect of the broken lint of the air chamber 10, and the air jet loom 12 can be powered off and turned off. , and then start the driving motor 13 to drive the threaded rod 14 to rotate, and the end of the threaded rod 14 away from the driving motor 13 is rotatably installed on the end of the collecting chamber 17 close to the special-shaped groove 15, so that the threaded rod 14 can be supported to rotate.
