Description

Technical Field

[0001] The present application relates to the technical field of rapier looms, and particularly to a rapier loom harness frame suction type harness threading structure. Background Art

[0002] The harness frame is an important component in a loom, and is a frame with harness rods and driving members connected by upper and lower cross beams and left and right side rails. Harness wires are arranged on the harness frame to gather the warp threads passing through the harness wires into one body. With the movement of the loom harness lifting mechanism, the harness frame moves up and down according to the program of the shedding device, so that the warp threads are separated into layers to form openings, allowing the weft yarn to shuttle through the warp threads and interweave into fabrics with different patterns.

[0003] In the patent with the published authorization announcement number CN219670771U, the rapier loom harness frame suction type harness threading structure includes a frame, and two groups of harness rods symmetrically arranged up and down in the frame. Connecting sleeves that are sequentially abutted against each other are sleeved on the harness rods. Threaded holes are provided on the outermost connecting sleeves, and fastening screws are screwed into the threaded holes. A steel sheet is vertically downwardly arranged on the connecting sleeve of the upper harness rod. A harness eye is provided at the lower end of the steel sheet. A wire clamp is provided on the steel sheet above the harness eye. A suction pipe is vertically upwardly arranged on the connecting sleeve of the lower harness rod. The upper end of the suction pipe is connected to the lower end of the steel sheet and the upper end of the suction pipe is located below one side of the harness eye. The inside of the lower harness rod is hollow, and a long strip-shaped through hole is provided on the upper side wall of the lower harness rod corresponding to the position of the connecting sleeve. A connecting hole communicating the long strip-shaped through hole and the suction pipe is provided on the connecting sleeve of the lower harness rod. An air inlet and outlet is provided at one end of the lower harness rod, and the air inlet and outlet is connected to an air pump through a pipe.

[0004] When the above device is implemented, after the wire is sucked into the suction pipe, the staff needs to hold a hook in their hand to hook it out of the suction pipe. However, the above device does not provide a placement and connection structure for the hook, resulting in the hook needing to be carried and stored by the staff at will. Since the hook is small in size and relatively sharp, it is easy to be lost and cause harm to the staff after being taken for a long time. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the present utility model provides a rapier loom harness frame suction type harness threading structure, which overcomes the deficiencies of the prior art and aims to solve the problems in the background art.

[0016] By adopting the above technical solution, the device can be stably placed, thereby ensuring the stability of the device and ensuring that it will not shake or tip over during use.

[0017] As a preferred embodiment, the number of the straws is several, and the shunt pipe is fixedly connected to the several straws.

[0018] By adopting the above technical solution, when the driving air pump operates, the gas can be extracted from the inner walls of the shunt pipe and several straws to the outside through the connecting pipe, thereby forming a negative pressure.

[0032] Refer to Figure 1 , a bracket is fixedly installed at the bottom of the frame 1, and the air pump 18 is fixedly installed on the top of the bracket, so that the bracket can be used to fix the air pump 18, ensuring the stability of the air pump 18 during operation and preventing it from shaking.

[0033] Refer to Figure 3 - Figure 5, a chute 17 is provided at the inner top of the frame 1, and both the slider 16 and the slide bar 8 are slidably connected to the inner wall of the chute 17, which facilitates the positioning of the vertical rod 15 and the connecting plate 7, ensures that the vertical rod 15 and the connecting plate 7 will not shake easily, and then the pressing plate 6 can be used to position the straw 5 and can also position the magnetic attraction block 9 to ensure that the magnetic attraction block 9 will not shake easily.

[0034] Refer to Figure 5 , the tops of the support plate 4 and the pressing plate 6 are both arc-shaped, and the outer edges of the straw 5 are closely attached to the tops of the support plate 4 and the bottom of the pressing plate 6 respectively, so that the support plate 4 and the pressing plate 6 can be used to position the straw 5 arranged on the inner wall of the arc to ensure that the straw 5 will not shake when there is air flow inside.

[0035] Refer to Figure 5 , the straw 5 is made of magnetic material, one end of the straw 5 close to the magnetic attraction block 9 is the outlet, and the other end is the inlet. The inner wall diameter of the perforation 10 gradually decreases from the side close to the straw 5 to the other side, so that the magnetic attraction principle can be used to stably adsorb and fit the magnetic attraction block 9 and the straw 5, and then ensure that the inner wall of the perforation 10 corresponds to the inner wall of the straw 5.
