High-speed broad-width paper-making felt needling device

Abstract

The invention relates to a high-speed broad-width paper-making felt needling device, which belongs to the paper-making felt needling device. The needling device comprises two main supports, a traveling vehicle is arranged in front of the main supports, a tension device is connected behind the main supports, a main beam is connected between the upper ends of the two main supports, a suspension beam is connected below the main beam, the operation end of the suspension beam is fixed on the support on the operation side, and a top beam is connected on the bottom end at the cloth end below the suspension beam; an electrical operation table is connected on the outer side of the main support on the operation side through an operation frame; a dragging bed is connected at the upper end of the suspension beam; and a third needling device is connected on the suspension beam, a pressure roller and a guide roller are connected on two sides of the upper end of the suspension beam, the pressure rollers are connected on the two sides of the lower end of the suspension beam, a stepping motor is connected on one side of the suspension beam, and a transmission pin shaft is arranged behind the main supports. The high-speed broad-width paper-making felt needling device has the advantages of improving performances of the device, monitoring the whole working conditions, timely reporting faults of the device, reducing the labor intensity of workers, improving working efficiency, enabling the device to operate stably and realizing smaller vibration and low power consumption.

Description

technical field [0001] The invention relates to a needle-punching device for papermaking felt, in particular to a high-speed and wide-width papermaking felt needlepunching device. Background technique [0002] At present, in order to meet the needs of papermaking machinery, papermaking felt enterprises provide papermaking felts with wider door width, faster speed and higher line pressure for papermaking machinery. The machines used to make paper blankets mainly include needlelooms for papermaking felts, and the existing needlelooms for papermaking felts mainly include single-needle zone needlelooms and double-needle zone needlelooms. Both the single-needle area needling machine and the double-needle area needling machine have a main frame, a blanket roller, an acupuncture device, a reducer, an electric motor, a cantilever support and a rotating device. After lowering the top beam of the needle loom, it is necessary to rotate the suspension beam part of the needle loom, whic...

AI Technical Summary

Problems solved by technology

After lowering the top beam of the needle loom, it is necessary to rotate the suspension beam part of the needle loom, which is inconvenient to operate, and has high requirements for the support and rotation equipment of the suspension beam and the venue for the upper and lower blankets of the needle loom. Larger vibrations are also likely to occur during the production process of acupuncture machines, which will affect the stability of equipment operation and reduce product quality.

[0003] The single-needle area acupuncture device has disadvantages such as small width, many times of needling, complicated operation, time-consuming, high labor intensity, etc.; the double-needle area acupuncture device has a wider width Large, the number of needling times has been reduced, but there are disadvantages of complicated operation and high labor intensity
