Problems solved by technology

With this connection method, the heald lifting foot swings vertically up and down, driving the heald frame connecting rod to move up and down and at the same time produce a small back and forth swing. This back and forth swing will cause the lifting lugs to wear and shorten the service life.
When the height is adjusted through the screw rod, it will cause the deflection of the upper connection of the heald frame connecting rod, and the connection of the lifting lug will be poor.
[0005] Therefore, it is necessary to design a new crank opening heald frame connecting rod to adapt to the J-type and C-type heald frame structures, so as to solve the problems of heald frame disassembly, running wear, and inconvenient adjustment.

Embodiment 1

[0035] combine Figure 1 to Figure 4 , a crank opening loom heald frame connection device, comprising a first upper connection seat 1, a first connection bushing 2 is arranged inside the first upper connection seat 1, and the lower end of the first upper connection seat 1 passes through a first connection pin 21 Rotationally connected with the first upper rotating block 3, the lower end of the first upper rotating block 3 is connected with the first upper gear rod 4, and the lower end of the first upper gear rod 4 is movably connected with the first middle connection through the first pressing mechanism 5. Seat 6, the bottom of the first middle connecting seat 6 is connected with the first lower rack 8 through the second pressing mechanism 7, and the lower end of the first lower rack 8 is connected with the first lower connecting seat 9.

[0036] The first upper connecting seat 1 comprises the first upper square block 11 and the first lower U-shaped block 12, the first lower U...

Embodiment 2

[0051] When the above-mentioned heald frame connecting device of the open crank loom is used, it is used to connect the heald frame structure and the heald lifting foot structure on the loom. During the weaving operation of the loom, the first upper connecting seat 1 is fastened to the heald frame connecting shaft 911 of the J-shaped heald frame structure 91 through the first connecting bush 2 . The middle of the first upper connection seat 1 is provided with a first connection bushing 2 to avoid wear when the first upper connection seat 1 and the heald frame connection shaft 911 swing in the left and right directions, and improve the smoothness of rotation. When the crank loom runs up and down, the position of the heald frame can be adjusted in real time through the heald frame connecting device that can swing back and forth, so as to avoid wear and tear when the heald frame runs up and down. The first upper connecting base 1 is connected with the first upper rotating block 3...

Abstract

The invention discloses a heald frame connecting device of a crank shedding loom. The heald frame connecting device of the crank shedding loom comprises a first upper connecting seat, wherein a firstconnecting bush is arranged in the first upper connecting seat; the lower end of the first upper connecting seat is rotatably connected with a first upper rotating block through a first connecting pin; the lower end of the first upper rotating block is connected with a first upper toothed rod, and the lower end of the first upper toothed rod is movably connected with a first middle connecting seatthrough a first pressing mechanism; the lower portion of the first middle connecting seat is connected with a first lower toothed rod through a second pressing mechanism; and the lower end of the first lower toothed rod is connected with a first lower connecting seat. The first middle connecting seat comprises a first square shell, a first strip-shaped block and a second strip-shaped block are fixedly connected to the left and right inner side end walls of the first square shell respectively, and a plurality of parallel first strip-shaped tooth grooves are vertically formed in the inner sideend face of the first strip-shaped block. The device is conveniently used for connecting heald frames in the shedding loom, and is adjustable in length, rotatable, and convenient and simple to use.

Description

technical field [0001] The invention relates to the field of air-jet looms, in particular to a heald frame connecting device for a crank shedding loom. Background technique [0002] The healds of J-type and C-type heald frames are riveted and fixed on the heald frame profiles, and are generally used on high-speed looms because of their strong rigidity and the smoothness of the healds on the heald frames. Existing J-type and C-type heald frames are mostly used on looms with cams or dobby openings. The heald frame lugs are connected with the suspension rings on the pull rod assembly of the cam or dobby shed. The connection is on the same plane, we call it lateral swing, this structure is a plane connecting rod transmission, which is very reasonable, there is a clamping device on the lifting lug assembly, which can facilitate the disassembly of the heald frame, when changing the fabric It is convenient to remove the heald frame and thread the yarn. [0003] The crank opening ...
