Joint-free industrial felt needle machine

Abstract

An industrial woolen textile needle machine without adapter belongs to the technical field of non-woven machinery and includes a machine frame provided with bottom beam, an outer needle mechanism arranged on a first transverse beam of the machine frame for needling one side of the non-woven fiber base cloth and an inner needle mechanism arranged on a second transverse beam correspondingly below the outer needle mechanism for needling the other side of the non-woven fiber base cloth; one end of the second transverse beam is articulated with one side of the machine frame, and the other end becomes a free end; one end of the machine frame which is correspondingly articulated with the second transverse beam is provided with a transverse beam driving device which is connected with the second transverse beam for driving the second transverse beam to move; the other side of the machine frame is provided with a locking device for locking or opening the free end of the second transverse beam. The invention can process paper making felts and conveyor belts with broad width and without adapter; during processing, the locking device is controlling without need of turning over the felts and belts manually, which can reduce the labor intensity of workers and improve the processing efficiency.

Description

technical field [0001] The invention relates to a jointless industrial wool needle loom, which belongs to the technical field of non-woven machinery. Background technique [0002] The non-joint industrial cloth, from its literal interpretation, is the endless industrial cloth, which is formed as a ring body as a whole. Non-woven products belonging to the category of non-joint industrial woolen products are mainly but not limited to products such as paper-making blankets and various conveyor belts. Due to their strict use requirements, the existence of joints is usually taboo for such products. Because, if there are joints, on the one hand, it will make it difficult to guarantee the strength of the blanket and the belt itself, and the durability will be poor, and cracks or even breaks will appear at the joints without long-term use, resulting in scrapping; If the blanket is used, the thickness of the paper will be affected, the quality of the paper product cannot be guarante...

Problems solved by technology

At present, the process of obtaining paper-making blankets or conveyor belts with a narrow width such as a width of about 1 meter is: use a traditional acupuncture machine to perform acupuncture according to the process requirements (gram weight) to obtain long strips with two corresponding endpoints. Then use equipment such as industrial sewing machines to join the ends, so the joints are not smooth and uneven. Even the best skills cannot meet the requirements of seamless butt joints, or there are obvious seams, or there are Overlapped intersection area, this kind of blanket is used as a papermaking felt, which can only meet the production requirements of low-grade paper products; used as a conveyor belt, only suitable for occasions with lower process requirements

[0004] The simple-structure non-joint industrial needlelooms mainly include gantry-type single / double-needle zone needlelooms. The details can be understood from Figure 8 given by the applicant. This figure is for the double-needle zone. The so-called The double-needle area refers to a pair of first and second acupuncture mechanisms 1 and 2 arranged in parallel, that is, there are two acupuncture areas, two needle beams and two rows of needle beds, and there is no joint with the single-needle area. Compared with the woolen needle loom, it has made a little progress in terms of production capacity, but there are two substantive problems: in the process of processing the blanket and belt, it must be turned over or turned over, that is, it is completed on one side of the blanket or belt. After needling, the blanket and belt need to be turned over in the shutdown state to complete the needling on the other side of the blanket and belt. This intermittent (intermittent) processing method constitutes an obstacle to the stability of product quality, especially in the The blanket and belt are easily damaged during the process of turning over the blanket and belt, and the actions of turning over the blanket and belt are all done manually by workers, which is labor-intensive and inefficient; it can be seen from the structure shown in the figure that one end of the needle beam 3 should be hinged. The other end is the pin support 4 (also known as the positioning pin support). When the base cloth 7 is fed to the first and second acupuncture mechanisms 1 and 2 for acupuncture, one end of the needle beam 3 must be used first. Lift the hoisting chain 5 on the gantry 8, then pull out the latch 6 from the latch support 4, put the base cloth 7 on or drop half of the blanket and belt, then insert the latch 6 onto the latch support 4, Remove the suspension chain 5, put on the base cloth 7 or drop (take off) the other half of the blanket and belt at last, so the operation process is very cumbersome

[0006] In recent years, with the continuous updating of papermaking equipment, the width of the non-woven papermaking blanket required by it has reached more than 5 meters, or even 10 meters or wider. The requirements for paper-making felts cannot be met by the aforementioned processing equipment. As a result, my country's paper-making manufacturers have to purchase paper-making felts with a width of more than 5m from abroad at an expensive price of about 150 yuan per kilogram, and the price has always been trending toward the same level. Due to the rising trend, this has restricted the development of my country's paper industry to a certain extent and made paper companies a cost burden, which eventually caused high paper prices and pressure on consumption.
