Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of jacquard machine leash equipment, in particular to a simple leash hook assembly. Background Art
[0002] The application range of jacquard machines is very wide, including clothing, home textiles, automobiles, construction and other fields. With the development of technology, the types of jacquard machines are also increasing. From traditional mechanical jacquard machines to modern electronic jacquard machines, they can meet the requirements of high quality and high productivity.
[0003] The traditional jacquard machine is mainly composed of a transmission mechanism, a heald lifting mechanism, a pattern control mechanism, a warp yarn system, and a driving component. The lifting knife in the heald lifting mechanism is generally connected to the heald to lift and lower the warp yarn. When working, some healds need to be twisted as the edge of the cloth, and people are generally tied to the lifting knife.
[0004] However, the healds are tied to the lifting knife, and it is very troublesome to adjust the position of these healds on the lifting knife later. Since there is a certain friction between the healds and the outer wall of the lifting knife, pushing them can easily cause damage to the healds. At the same time, during the movement of the lifting knife, these healds are also prone to deviation, affecting the subsequent twisting work. Utility Model Content
[0005] The purpose of the utility model is to overcome the above-mentioned deficiencies of the prior art and provide a simple twisted edge hook assembly.
[0006] The above technical purpose of the present utility model is achieved through the following technical solutions: a simple hem hook assembly, comprising a hem hook arranged on a knife lifting member, a support portion being provided at one end of the knife lifting member, a sliding portion being provided on the hem hook and slidingly arranged with the support portion, and a positioning member at one end of the hem hook for winding the heald.
[0007] Preferably, the positioning member includes a threaded portion and a winding portion, the threaded portion and the winding portion are integrally formed, the twisted edge hook is provided with an internal thread that is threadedly engaged with the threaded portion, and the winding portion is hollow.
[0008] Preferably, a limiting plate is provided on the outer wall of the knife lifting member, and the limiting plate is connected to the knife lifting member via a fastening screw.
[0009] Preferably, the support portion is provided with sliding surfaces on opposite sides of the knife lifting member, and the sliding portion is provided with two groups, which are respectively slidably matched with the two groups of sliding surfaces.
[0010] Preferably, the limiting plate is arranged on the sliding surface.
[0011] Preferably, at least two groups of the limiting plates are provided, which are respectively arranged on the two groups of sliding surfaces.
[0012] The beneficial effects of the utility model are as follows: a support portion is provided on the knife lifting member for the sliding portion of the twisted edge hook to slide, and the twisted edge hook on the knife lifting member is positioned by the positioning member. Compared with the prior art, there is no need for the heald to directly slide in contact with the surface of the knife lifting member, which reduces friction damage to the heald. At the same time, the winding portion on the positioning member makes it convenient for personnel to wind and connect the heald, and personnel adjust the position of the heald, which makes operation simpler and more convenient.

[0017] The following is only a preferred embodiment of the present invention, and the scope of protection is not limited to this embodiment. All technical solutions under the concept of the present invention should fall within the scope of protection of the present invention. At the same time, it should be pointed out that for ordinary technicians in this technical field, several improvements and modifications without departing from the principle of the present invention should also be regarded as within the scope of protection of the present invention.
[0018] It should be noted that in this article, relational terms such as first and second, such as "connector board one, connector board two", etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
[0019] The directional words mentioned in this embodiment, such as "up, down, left, right", etc., are only used in conjunction with the drawings to enable technicians in this technical field to understand the relationship between various features or parts.
[0020] In this embodiment, unless otherwise clearly specified and limited, the terms "connection", "fixed", etc. should be understood in a broad sense. For example, "fixed" can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in this utility model according to specific circumstances.
[0021] like Figures 1 to 3 As shown, a simple hem hook assembly includes a hem hook 2 arranged on a knife lifting member 1, support parts 3 are relatively arranged at the upper and lower ends of the knife lifting member 1, and the two sets of support parts 3 are arranged in parallel on the adjacent sides, and a sliding part 4 parallel to the support part 3 is provided on the hem hook 2, and the support part 3 is located on the front and rear sides of the knife lifting member 1 and is provided with a sliding surface 9. The hem hook 2 can slide with the sliding surface 9 through the sliding part 4. It should be noted that personnel can rotate and set rollers on the sliding surface 9 according to actual application (not shown in the drawings) to further reduce the contact friction between the sliding part 4 and the sliding surface 9.
[0022] A positioning piece is provided in the middle of the end of the hem hook 2 away from the support part 3, and the positioning piece includes a screw part and a winding part 7 integrally formed therewith. An internal thread that is screwed with the threaded part 6 is provided on the end of the hem hook 2 away from the support part 3, and the winding part 7 is hollow, and the middle part is for the heald to pass through, and the hollow range can be changed by personnel according to actual replacement and adjustment to allow more or less healds to pass through.
[0023] A rectangular limiting plate 5 is provided on the outer wall of the knife lifting member 1, and the limiting plate 5 is fixed to the knife lifting member 1 by a fastening screw 8. In this embodiment, one side of the limiting plate 5 is in contact with the sliding surface 9. Its purpose is to limit the range of sliding of the hem hook 2 along its length on the knife lifting member 1 to avoid affecting other healds. Personnel can set the same number of limiting plates 5 on the knife lifting member 1 and limit them according to the number of hem hooks 2 actually used.
[0024] When the personnel adjusts the heald on the edge of the knife lifting member 1, they first slide the hedged hook 2 on the knife lifting member 1. After moving to the appropriate position, the threaded portion 6 of the positioning member is screwed into the internal thread of the hedged hook 2, and the bottom end of the threaded portion 6 of the positioning member is fixed to the outer wall of the knife lifting member 1. The head end of the heald is circled and knotted and then put on the winding portion on the hedged hook 2, thereby avoiding the personnel from manually sliding the heald on the outer wall of the knife lifting member 1, reducing the problem of wear caused by direct contact between the heald and the knife lifting member 1, and also avoiding the heald being indirectly driven to the position on the knife lifting member 1 when the knife lifting member 1 moves.
[0025] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention falls within the scope of protection of the present invention.
