Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, and in particular to a jacquard opening device. Background Technology

[0002] The jacquard shedding device is one of the key pieces of equipment in textile machinery. It is mainly used to control the shedding action of warp yarns during the weaving process. During weaving, the warp yarns need to move up and down according to a certain pattern to form a shed, allowing the weft yarns to pass smoothly and interweave to form the fabric. The jacquard shedding device, through its complex mechanical structure and control system, precisely controls the movement of each warp yarn, enabling the fabric to display intricate patterns.

[0003] Currently, the swing arm connection of jacquard sheathing devices generally adopts a concentric or dual-axis structure, supported by left and right side panels. Some sheathing devices are designed with adjustable swing arms using holes at different positions to achieve different sheathing volumes. However, during movement, the pull rod is not vertical and has a large angle with the vertical direction, generating a horizontal component force. This causes the lifting rod seat to press against the guide rod, accelerating guide rod wear, shortening its service life, and increasing after-sales costs. Utility Model Content

[0004] The purpose of this invention is to provide a jacquard opening device that solves the technical problem of the service life of existing jacquard opening devices.

[0005] This application discloses a jacquard opening device, comprising:

[0006] beam;

[0007] A cam mechanism is mounted on the side of the crossbeam;

[0008] A linkage mechanism is installed on the outside of the crossbeam and is connected to the cam mechanism;

[0009] A blade lifting assembly is mounted on the crossbeam and is connected to the linkage mechanism;

[0010] The linkage mechanism includes:

[0011] The connecting rod swing arm shaft is mounted on the crossbeam;

[0012] The connecting rod swing arm is movably mounted on the end of the connecting rod swing arm shaft;

[0013] A connecting rod is installed at the end of the connecting rod swing arm, and the connecting rod is connected to the lifting assembly.

[0014] A mounting hole is opened at both ends of the connecting rod swing arm, and there are two connecting rods, with each connecting rod corresponding to one of the mounting holes;

[0015] The cam mechanism includes:

[0016] The cam swing arm shaft is mounted on the crossbeam;

[0017] A cam rocker arm is installed at the end of the cam rocker arm shaft, and the cam rocker arm is located outside the crossbeam. The cam rocker arm is provided with a plurality of mating holes spaced apart.

[0018] The first connecting rod has one end fitted with the mating hole of the cam rocker arm, and the other end connected to the connecting rod mechanism.

[0019] This application designs the linkage mechanism and cam mechanism, and improves the opening amount adjustment method. This not only makes the opening amount adjustment more convenient, but also ensures that the connecting rod is basically vertical during the opening amount adjustment, resulting in very small horizontal force during the movement. This reduces the friction between the tool holder and the guide rod, minimizes the wear on the guide rod, improves its service life, and reduces after-sales costs.

[0020] Based on the above technical solution, the embodiments of this application can be further improved as follows:

[0021] Furthermore, the crossbeam consists of two pieces, spaced apart;

[0022] Two linkage mechanisms are spaced apart on the outer side of each crossbeam. The advantage of this step is that the two crossbeams facilitate the assembly of subsequent components.

[0023] Furthermore, the linkage mechanism includes a linkage rocker arm, which is installed at the end of the linkage rocker arm shaft and is located on the outside of the crossbeam. The advantage of this step is that the linkage rocker arm can work in conjunction with the subsequent linkage to achieve linkage.

[0024] Furthermore, the connecting rods of the linkage mechanism located on the same side are connected by a second connecting rod;

[0025] The first link is connected to the link mechanism near the cam rocker arm. The advantage of this step is that it enables the cooperation between the various components through the link.

[0026] Furthermore, the length of the second link is greater than the length of the first link.

[0027] Furthermore, the cam mechanism includes:

[0028] Conjugate cam;

[0029] The cam rocker arm, mounted on the cam rocker arm shaft, is used to provide power.

[0030] Furthermore, the blade lifting assembly includes:

[0031] Tool holder;

[0032] A lifting rod seat connector is installed at the end of the lifting rod seat, and the lifting rod seat connector is connected to the connecting rod.

[0033] A lifting lever is installed at the bottom of the lifting lever seat;

[0034] The blade lifting plate is installed at the end of the blade lifting rod. The advantage of this step is that the blade can be lifted by connecting the corresponding components.

[0035] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0036] 1. This application designs a connecting rod swing arm to achieve a vertical setting of the connecting rod tie rod, which can reduce friction and improve the service life of the device.

[0037] 2. This application designs a cam rocker arm that can adjust the opening amount through different mating holes to meet user needs.

[0038] 3. This application simplifies the adjustment of the opening amount, requiring only two adjustments, which improves work efficiency.

[0039] 4. The motion trajectory of the connecting rod in this application is approximately in a straight line with the motion direction of the tool lifting rod seat. The connecting rod is basically vertical, and the horizontal component force generated during the motion is very small. The friction between the tool lifting rod seat and the guide rod is relatively small, and the wear of the guide rod is very small, which improves the service life of the guide rod and reduces after-sales costs.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0052] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0053] Example 1:

[0054] like Figure 1-2As shown in the embodiment of this application, a jacquard opening device is disclosed, which is an improved solution for the connection between the connecting rod and the conjugate cam. Instead of the original rocker arm having different holes to accommodate the installation of the pull rod, it is changed to have only one hole, and adjustment is achieved through different holes on the rocker arm of the cam part.

[0055] like Figure 1 , 2 As shown, its specific structure is as follows, including:

[0056] Crossbeam 1 consists of two pieces, spaced apart, namely a front crossbeam and a rear crossbeam, which are arranged parallel to each other.

[0057] Cam mechanism 2 is installed on the side of the crossbeam 1. Specifically, cam mechanism 2 is installed on the front crossbeam. The power source of this application can be an independent drive motor (not shown in the drawings) to directly drive cam mechanism 2, or the loom can drive cam mechanism 2 through the lower commutator, vertical shaft, and upper commutator (not shown in the drawings).

[0058] Linkage mechanism 3 is installed on the outside of the crossbeam 1 and is connected to the cam mechanism 2. The cam mechanism 2 provides power to drive the linkage mechanism 3 to move, thereby driving the subsequent blade lifting assembly to move.

[0059] The knife-lifting assembly 4 is installed on the crossbeam 1 and is connected to the linkage mechanism 3. Part of the knife-lifting assembly 4 extends out of the crossbeam and cooperates with the linkage mechanism 3 located on the outside of the crossbeam 1, thereby driving the knife-lifting assembly 4 to move.

[0060] The linkage mechanism 3 includes:

[0061] The connecting rod swing arm shaft 301 is installed on the crossbeam 1;

[0062] The connecting rod swing arm 302 is movably mounted on the end of the connecting rod swing arm shaft 301;

[0063] A connecting rod 303 is installed at the end of the connecting rod swing arm 302, and the connecting rod 303 is connected to the lifting assembly 4.

[0064] Specifically, a mounting hole 304 is provided at both ends of the connecting rod swing arm 302, and there are two connecting rods 303, with each connecting rod 303 corresponding to one of the mounting holes 304. In this application, the connecting rod swing arm 302 is designed to connect with the connecting rod 303 through only one hole, simplifying assembly. The specific adjustment is made by different engagements of the subsequent cam swing arm.

[0065] In one embodiment, the cam mechanism 2 includes:

[0066] Cam swing arm shaft 201 is mounted on the crossbeam 1;

[0068] The first connecting rod 204 is assembled at one end with the mating hole of the cam rocker arm 202 and at the other end with the connecting rod mechanism 3. That is, the cam rocker arm 202 is designed in this application to adjust the corresponding opening amount by using different mating holes 203 (the mating holes 203 are set at intervals along the length direction of the cam rocker arm), which simplifies the original adjustment method and can improve work efficiency.

[0069] Regarding the foregoing, the crossbeam 1 consists of two pieces, and each crossbeam 1 has two connecting rod mechanisms 3 spaced apart on its outer side.

[0070] Specifically, the linkage mechanism 3 includes a linkage swing arm 305, which is installed at the end of the linkage swing arm shaft 301 and is located on the outside of the crossbeam 1.

[0071] Among them, the connecting rods 305 of the linkage mechanism 3 located on the same side are connected by a second connecting rod 306;

[0072] The first link 204 is connected to the link 305 of the link mechanism near the cam rocker arm 202, and the length of the second link 306 is greater than the length of the first link 204.

[0073] The cam mechanism 2 includes:

[0074] Conjugate cam 205;

[0075] Cam rocker arm 206 is mounted on cam rocker arm shaft 201.

[0076] The blade lifting assembly 4 includes:

[0077] Tool holder 401;

[0078] The lifting rod seat connector 402 is installed at the end of the lifting rod seat 401, and the lifting rod seat connector 402 is connected to the connecting rod 303;

[0079] The lifting lever 403 is installed at the bottom of the lifting lever seat 401.

[0080] Further explanation of the specific structure of this application:

Two shaft fixing seats are installed at the front and rear ends of the connecting rod rocker arm shaft 301, respectively. One shaft fixing seat is installed on the front crossbeam, and the other shaft fixing seat is installed on the rear crossbeam.

[0083] The two connecting rods 305 are connected by a second connecting rod 306, and the installation method of the remaining connecting rod mechanism is the same as described above.

[0088] This application installs the first connecting rod 204 on different mating holes 203 of the cam rocker arm 202, which can realize different lifting heights for each row of blades, i.e. different opening amounts.

[0089] Sixteen guide rods are installed on the crossbeam to ensure that the lifting rod seat, lifting rod seat, lifting rod seat, and lifting rod seat can only move up and down.

[0090] The connecting rod is equipped with a waist-shaped hole for adjusting the height of the lifting rod seat, lifting rod seat, lifting rod seat, and lifting rod seat, ensuring that when the lifting rod is at its highest point, it can press against the moving lifting pin of the component (not shown in the drawing).
