Description

The guiding device for the movement of the brown frame of the multi-pattern natural fiber jacquard loom

technical field

The invention relates to the field of textile machinery preparation, in particular to a loom for preparing carpets from plant fibers, and more particularly to a sisal carpet loom capable of producing various patterns.

Background technique

The main raw materials of natural fiber carpet are sisal, jute, water grass, mat grass, cattail grass, corn husk and other fibers. It is an all-natural product. It contains moisture and can absorb moisture or release moisture to adjust the environment and air temperature as the environment changes. , At the same time, it also has the advantages of energy saving, degradable, insect-proof, flame-retardant, anti-static, high elasticity, sound absorption, heat insulation, and wear resistance. With the improvement of people's living standards, carpets such as sisal, bamboo, jute, water grass, mat grass, cattail grass, and corn husks are widely used in hotels, offices and home decoration. As far as the fabric itself is concerned, in order to beautify the indoor environment, natural fiber carpets not only have plain weave, twill weave, but also jacquard, especially jacquard natural fiber carpets. After being used for interior decoration, it gives people a grand and elegant enjoyment. However, the current jacquard natural fiber carpets can generally only produce some simple warp and weft weaving, and cannot be jacquard. The transmission mechanism of the palm frame adopts the heart crank device combined with the lever and the rotary cam. Therefore, limited by the circumference of the cam, each loom can only have four palm frames at most, otherwise, the height of the palm frame is lifted. Production requirements cannot be met. On the same day, the applicant filed a patent application for "Multi-pattern Natural Fiber Carpet Jacquard Loom", which solved this problem well. According to the needs, multiple palm frames can be installed on the loom to weave carpets of various patterns to meet the needs of the market. need.

A further improvement of the present invention is that the wheel is a sprocket, or a pulley with a groove in the middle;

Be arranged on the wheel of carrying palm frame, its wheel axle is fixedly connected in carrying palm frame, be arranged on the wheel on the frame of palm frame bottom, its wheel axle is firmly connected in frame.

The further improvement of the present invention is that the cable connected to the upper frame of the brown frame passes through the wheel vertically upwards and then is connected to the upper tie rod, and one end of the upper rod is movably connected to the upper end of the swing arm; the cable connected to the lower frame of the brown frame After being guided vertically downward through the wheels, it is connected to the pull-down rod, and one end of the pull-down rod is movably connected to the lower end of the swing arm.

A further improvement of the present invention is that the upper and lower rods are arranged horizontally, and a limit device is provided, and the limit device is respectively connected to the lifting frame and the machine frame.

A further improvement of the present invention is that the limiting device is a bracket with a hole, one end of the bracket is connected to the lifting frame or the frame, and the other end is provided with a hole, and the upper and lower rods respectively pass through the bracket holes.

A further improvement of the present invention is that one end of the pull rod is movably connected to the swing arm, and a notch or a hole is provided outside the upper and lower ends of the swing arm. Located in the groove or hole, the other end of the clip is connected with the pull rod by a joint.

The guide device of the present invention is simple in structure, easy to manufacture, and more importantly, can ensure the accuracy of the guide, so that the palm frame of the loom can be lifted and lowered according to the technical requirements, and the jacquard quality of the jacquard carpet can be guaranteed. the
