Description

Technical Field

[0001] This utility model relates to the field of fabric processing technology, and in particular to a trimming mechanism and its water-jet loom. Background Technology

[0002] Water jet looms use high-pressure water jets to guide the weft yarns to weave fabrics. The fabrics produced by these looms typically have high density and smooth surface properties. After the fabrics are processed in the water jet loom, they need to be trimmed.

[0003] While some existing edge trimming technologies can achieve automatic edge trimming, in actual operation, due to the lack of an effective fabric fixing and flattening mechanism, the fabric is prone to displacement or deformation during the trimming process, resulting in inaccurate trimming or uneven edges. In addition, traditional edge trimming mechanisms often only focus on the cutting action itself, neglecting the processing of the fabric before and after trimming. This makes the edges of the trimmed fabric prone to curling, affecting the overall aesthetics and performance of the fabric, thus reducing the trimming effect. To address this, we propose an edge trimming mechanism and its water-jet loom. Utility Model Content

Detailed Implementation

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] This utility model provides, for example Figures 1-3 The shown edge trimming mechanism includes a fabric table 101, an edge trimming assembly, a pressing mechanism, and a squeezing mechanism. The edge trimming assembly is located at the top of the fabric table 101, and the pressing mechanism is also located at the top of the fabric table 101. The pressing mechanism is used to flatten the fabric to be trimmed. The squeezing mechanism is located between the pressing mechanism and the edge trimming assembly. When the edge trimming assembly descends to trim the fabric, the pressing mechanism descends along with it. However, the pressing mechanism first contacts the fabric and flattens it. Then, with the cooperation of the squeezing mechanism, as the edge trimming assembly continues to move downward, the pressing mechanism continues to flatten the fabric until the edge trimming assembly contacts the fabric and completes the trimming. During the trimming process, the edge to be trimmed is flattened by the pressing mechanism, which makes it less likely for the trimmed fabric to curl up, thereby improving the trimming effect of the fabric.

[0040] The trimming assembly includes a cutter holder 201, a fixing frame 204, and a hydraulic cylinder 205. The bottom end of the cutter holder 201 has a mounting groove 202, and a cutter 203 is installed inside the mounting groove 202. The fixing frame 204 is fixedly connected to the top of the fabric table 101. The hydraulic cylinder 205 is installed on the top of the fixing frame 204. The output end of the hydraulic cylinder 205 passes through the top of the fixing frame 204 and is connected to the top of the cutter holder 201. The operation of the hydraulic cylinder 205 drives the cutter holder 201 to descend, which in turn drives the cutter 203 to descend, so that the cutter 203 contacts the fabric for trimming. The hydraulic cylinder 205 is electrically connected to an external power supply through an external switch, which facilitates the operator's control of the hydraulic cylinder 205 and improves the safety and convenience of operating the hydraulic cylinder 205.

[0041] The pressing mechanism includes a pressing block 301 and a rubber pad. The pressing block 301 is located on both sides of the cutter 203. The extrusion mechanism is located between the pressing block 301 and the cutter holder 201. The rubber pad is located at the bottom of the pressing block 301. When the cutter holder 201 descends, it will drive the pressing block 301 to descend as well, so that the rubber pad can first contact the fabric for flat pressing. At the same time, the rubber pad will not cause hard compression to the fabric, thereby avoiding the fabric from being crushed. The outer wall of the pressing block 301 has multiple ball holes, and each ball hole is equipped with a rolling ball. The rolling ball contacts the cutter 203, so that the cutter 203 moves more smoothly relative to the pressing block 301.

[0042] The extrusion mechanism includes a connecting block 401 and a first spring 402. A connecting mechanism is provided between the connecting block 401 and the knife holder 201. The first spring 402 is located between the bottom end of the connecting block 401 and the top end of the pressure block 301. When the rubber pad at the bottom end of the pressure block 301 contacts the fabric, the pressure block 301 cannot descend. At this time, the first spring 402 will be compressed, so that the rubber pad at the bottom end of the pressure block 301 can stably press the fabric flat.

[0043] The bottom end of the connecting block 401 is fixedly connected to a connecting sleeve 501, which is inserted into the inside of the first spring 402. The bottom end of the connecting sleeve 501 has a connecting hole 502, and the inner wall of the connecting hole 502 is movably connected to a connecting rod 503. The bottom end of the connecting rod 503 is fixedly connected to the top end of the pressure block 301, and the top end of the connecting rod 503 is fixedly connected to a limiting block 505. The inner wall of the connecting hole 502 has a limiting cavity 504, and the outer wall of the limiting block 505 is slidably connected to the inner wall of the limiting cavity 504. Through the connection of the connecting rod 503 and the connecting sleeve 501, the connection between the pressure block 301 and the knife holder 201 is made more stable.

[0044] The connecting mechanism includes a first slider 702, a second slide groove 703, and a second slider 704. The second slider 704 is fixedly connected to the top of the connecting block 401. The second slide groove 703 is opened on one side of the tool holder 201. The outer wall of the second slider 704 is slidably connected to the inner wall of the second slide groove 703. The first slider 702 is fixedly connected to the top of the second slider 704. The top of the inner wall of the second slide groove 703 is provided with the first slide groove 701. The outer wall of the first slider 702 is slidably connected to the inner wall of the first slide groove 701. A positioning mechanism is provided at the top of the first slider 702. When the first slider 702 is inserted into the first slide groove 701, the second slider 704 is inserted into the second slide groove 703. At this time, the second slide groove 703 will limit the first slider 702, so that the first slider 702 cannot move down. Then, the positioning mechanism fixes the first slider 702 in the first slide groove 701, thereby improving the stability of the pressing mechanism.

[0045] The positioning mechanism includes a movable hole 801, a positioning rod 802, a positioning hole 803, and a second spring 804. The movable hole 801 is located at the top of the inner wall of the first slide groove 701. The outer wall of the positioning rod 802 is movably connected to the inner wall of the movable hole 801. The positioning hole 803 is located at the top of the first slider 702. The outer wall of the positioning rod 802 is movably connected to the inner wall of the positioning hole 803. The second spring 804 is located at the top of the positioning rod 802. Through the elastic action of the second spring 804, the positioning rod 802 can be stably inserted into the positioning hole 803, thereby positioning the first slider 702 in the first slide groove 701.

[0046] The positioning rod 802 is fixedly connected to a connecting plate 902 on one side. A connecting groove 901 is provided on one side of the inner wall of the movable hole 801. The outer wall of the connecting plate 902 is slidably connected to the inner wall of the connecting groove 901. A sliding plate 903 is provided on one side of the tool holder 201. One side of the sliding plate 903 is fixedly connected to one side of the connecting plate 902. The sliding plate 903 is connected to the positioning rod 802 through the connecting plate 902. When the positioning mechanism needs to be unlocked, it is only necessary to move the sliding plate 903 on the outside of the tool holder 201, thereby improving the convenience of unlocking the positioning mechanism.
