Description

Technical Field

[0001] The utility model relates to a ribbon loom, in particular to a novel heald frame for ribbon loom and the ribbon loom. Background Art

[0002] Common fabric weaving processes include plain weave and twill weave. Compared with twill weave, plain weave has the following advantages: strong and wear-resistant, light and breathable, moderately elastic, easy to process, and good anti-snagging performance. These advantages just meet some of the performance requirements of the ribbon, so the plain weaving process is often used in the production of ribbons. As a ribbon production equipment, the loom can be used for plain weaving. The heald frame is an important component of the loom. It is a frame with a heald rod and a drive connected by upper and lower beams and left and right side gears. After the heald frame is equipped with a sheet heald, the warp yarns inserted into the sheet heald are assembled into one. With the movement of the loom heald lifting mechanism, the heald frame moves up and down according to the program of the opening device, so that the warp yarns are opened in layers, allowing the weft yarns to shuttle through the warp yarns and interweave into fabrics with different patterns.

[0003] There are many plate healds on the heald frame, and they need to be replaced or adjusted regularly. The existing plate heald fixing method on the heald frame is not convenient for quick replacement or adjustment of the plate healds, resulting in time-consuming and labor-intensive operation. For this reason, someone has disclosed a Chinese patent (CN220812808U) entitled "A heald device for a ribbon loom", which includes a first heald frame, a second heald frame, an adjustment component and a heald (plate heald). The first heald frame and the second heald frame are both connected to the adjustment component on both sides. The adjustment component consists of a first connecting seat, a connecting rod, a second connecting seat, a linear slide and a mounting seat. The middle of the second connecting seat is connected to a connecting rod, and the two ends of the connecting rod are connected to the first connecting seat. A wire hole is opened in the middle of the heald, and the upper and lower parts of the heald are provided with connecting columns, and multiple sets of limit nuts are connected to the connecting columns. The patent enables the heald to be assembled and adjusted to the position with the heald frame through limit nuts. Due to the large number of healds, the actual adjustment efficiency is still low, and it is difficult to ensure the uniform height of all healds. Summary of the invention

[0004] The utility model provides a novel heald frame for weaving belts and a weaving machine, which solve the problems in the prior art that the installation and adjustment efficiency of the plate healds on the heald frame is low and the height of the plate healds is difficult to adjust uniformly.

[0005] The above technical problems of the utility model are mainly solved by the following technical solutions: a new type of heald frame for webbing, comprising an upper beam, a lower beam, two side guards and a sheet heald, the side guards are generally installed in a bolted manner with the upper beam and the lower beam, and a guide strip is arranged on the outer side of the side guard, characterized in that: the upper beam is slidably matched with a heald frame, the heald frame is constrained by the upper beam to slide up and down, the heald frame is provided with a horizontally distributed upper guide groove, the lower beam is provided with a horizontally distributed lower guide groove, a plurality of heald blocks are slidably matched in both guide grooves, and the heald blocks in the two guide grooves are vertically opposite to each other, and the heald blocks are provided with There is a hanging rod, hanging holes are provided at both ends of the sheet heald, a lead hole is provided in the middle of the sheet heald, the side guard is detachably matched with the upper beam and the lower beam, and when the side guard is removed, the ends of the two guide grooves will be completely exposed, which is convenient for replacing the threading blocks thereon, and the upper beam is also horizontally slidably matched with two locking pieces, and the locking pieces are provided with an inclined guide surface, and the drawing frame is provided with a guide rod that fits with the guide surface, and the upper beam or the side guard is provided with a position adjuster that can adjust the position of the locking piece, and a connecting column is fixedly connected between the middle parts of the upper beam and the lower beam, and the connecting column separates the heald frame into a left heald frame and a right heald frame that are mirror-distributed.

[0006] Since the width of the webbing itself is narrow, the actual required width of the heald frame for producing a single webbing is not wide either. Therefore, the utility model separates the heald frame into a mirror-imaged left heald frame and a right heald frame through a connecting column, so that the utility model actually has two groups of heald frames, which has higher production efficiency. The installation and disassembly method of the sheet heald of the utility model is: loosen the position adjuster, remove the two side stops, so that the outer ends of the upper guide groove and the lower guide groove are completely exposed, and the locking piece is in a relaxed state at this time, so it is easy to take out all the heald blocks from the upper guide groove and the lower guide groove, and then remove the sheet heald that needs to be replaced, and then after the new sheet heald is docked with the heald block, the heald block is reinstalled into the upper guide groove and the lower guide groove, and then the two side stops are assembled back, and finally the position adjuster is locked, and the heald frame moves upward so that all the sheet healds are tightened.

[0007] Furthermore, the guide surface is provided with at least two places to ensure that the drawing frame is evenly stressed and remains horizontal. The guide rod is rotatably matched with a guide wheel that rolls with the guide surface. The function of the guide wheel is to reduce the friction generated when it is relatively displaced with the guide surface, reduce wear and increase service life.

[0008] Further, the position adjuster is a bolt member, which is horizontally screwed on the side guard, and its inner end abuts against the locking member. By tightening the bolt member, the locking member is moved to one side until the heddle frame is fully tightened, and this adjustment method is simple and fast.

[0009] Furthermore, an upper butt block and a lower butt block are provided on the inner side of the side guard, the upper butt block abuts against the upper threading block, and the lower butt block abuts against the lower threading block, to avoid lateral loosening of the threading block and ensure that the position and spacing of the sheet wedgies are fixed. The upper butt block and the lower butt block are generally made of rubber blocks.

[0010] The utility model also provides a weaving machine, comprising a weaving machine body and a heald frame arranged thereon, characterized in that the heald frame is the above-mentioned new heald frame for weaving. Since the above-mentioned new heald frame for weaving has the above-mentioned technical effects, the weaving machine having the heald frame also has the same technical effects.

[0011] Therefore, compared with the prior art, the utility model has the following characteristics: 1. The utility model controls the position of the locking piece laterally to achieve fine-tuning of the heddle frame up and down. When the heddle frame is tightened upward, all the sheet heddles are tightened and fixed synchronously, and the lead holes on the sheet heddle have good height consistency. After removing the side guard, the heddle frame is relaxed, and the heddle block and the sheet heddle can be easily removed. Therefore, the utility model has high replacement efficiency and precise positioning effect. BRIEF DESCRIPTION OF THE DRAWINGS
