Description

Technical Field:

[0001] The present invention relates to the technical field of textile equipment, and more specifically to a lifting drive mechanism for a heddle frame of a loom. Background Art:

[0002] The rapier loom is the most widely used shuttleless loom at present. In addition to the characteristics of high speed, high degree of automation, and high-efficiency production of shuttleless looms, its positive weft insertion method has strong variety adaptability and can adapt to the weft insertion of various yarns. Moreover, the rapier loom also has obvious advantages in multi-color weft weaving and can produce figured fabrics with up to 16 color wefts.

[0003] In an existing rapier loom, such as a multi-shed double-weft rapier loom, during operation, in order to meet different weaving requirements, the heddle frames arranged on the loom frame need to be adjusted in height to change the position of the warp threads to meet the weaving requirements;

[0004] The existing heddle lifting uses a cam shedding device, which is installed on a flexible rapier loom and is used to output the rotational speed to the heddle frames of the loom for shedding.

[0005] However, the output structure of the existing cam shedding device directly pulls the heddle frame through a steel wire rope, and its pulling effect is limited. Moreover, the steel wire rope is prone to deformation over time and its durability is limited; at the same time, there is no locking mechanism in the existing cam shedding device, and it is impossible to move all the heddle arms to the side, making it very troublesome and inefficient to replace the cam discs. Summary of the Invention:

[0006] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a lifting drive mechanism for a heddle frame of a loom. The lifting of its heddle frame uses a rigid connection for lifting, which is not easy to deform. Moreover, it has components such as a hand lever and a heddle pushing connecting rod that can move all the heddle arms to the right end, so that the cam discs are not pressed against, facilitating replacement and maintenance with good effects.

[0038] Furthermore, two positioning recessed holes are formed on the positioning block 74, one at the rear and the other at the upper front portion, and the ends of the inner rod portion of the pulling rod 71 correspond to the two positioning recessed holes.

[0039] Working principle: When in use, the camshaft 21 rotates through the rotation of the transverse transmission shaft 31, driving the four cam pieces 23 to rotate, which drives the cam driven rotor 251 of the adjacent heald arm 25 to rotate and swing left and right with the outer wall surface of the cam piece 23, so that the heald arm 25 swings left and right, so that the top of the heald arm 25 moves to the corresponding points a, b and c (which correspond to points a, b and c on the cam piece 23), the top of the heald arm 25 moves, driving the connecting rod 27 to move left and right, and the arc-shaped arm 12 formed on the upper part of the left lifting rocker arm 11 swings through the swing block 28, so that the left lifting rocker arm 11 rotates, and the right lifting rocker arm 17 is driven to rotate together through the heald connecting rod 16, so as to realize the corresponding heald frame 100 to move to a high and low positions, and when the top of the heald arm 25 moves to points a, b and c, the heald frame 100 moves to the corresponding heights of points A, B and C to realize the corresponding weaving;

[0040] During operation, the elastic tension of the spring assembly 41 causes the cam follower rotor 251 to move against the right side wall of the corresponding cam piece 23, and the tension of the right spring assembly 52 pulls the right lifting rocker arm 17 to ensure the normal operation of the equipment.

[0041] When maintenance is required, i.e., when the machine is stopped, at this time, due to the elastic tension of the spring assembly 41, all the cam follower rotors 251 are always pressed against the right side wall of the corresponding cam plate 23. Then, the handle head 72 is pulled outwards, so that the end of the inner rod part of the pulling rod 71 is removed from one of the positioning concave holes. Then, the handle 202 is rotated, so that the push harness crank 203 rotates, pushing the push harness connecting rod 204 to the right, so that the push bearing presses against the left side wall of the corresponding harness lifting arm 25 and moves to the right until point d shown in the drawing. At this time, the cam follower rotor 251 is separated from the cam plate 23. At the same time, the end of the inner rod part of the pulling rod 71 faces another positioning concave hole. Due to the elastic action of the spring 73, the end of the inner rod part of the pulling rod 71 is inserted into the positioning concave hole at this time to complete the locking. At this time, the cam plate 23 can be replaced very conveniently, with convenient replacement and good use effect.

[0042] Finally, the above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. Those of ordinary skill in the relevant technical field can still make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention. The patent protection scope of the present invention shall be defined by the claims.
