Joint-free industrial felt needle machine with four needle regions needle prick

Abstract

The utility model relates to a non-joint industrial wool needle loom with four needle zones, which belongs to the technical field of non-woven machinery. It includes a frame with a bottom beam, an outer needle punching mechanism for needle punching the outside of the non-woven fiber base cloth on the first beam of the frame, and an openable second needle punching mechanism on the frame. On the beam and corresponding to the inner needling mechanism for needling the inner side of the non-woven fiber base cloth under the outer needling mechanism, the outer needling mechanism constitutes a first and a second outer needling area, The inner needling mechanism is composed of first and second inner needling areas. Advantages: Since the outer and inner needling mechanisms respectively used to simultaneously needling the outer side and inner side of the non-woven fiber base fabric each constitute a pair of needling areas, it is possible to perform needling in four needling areas simultaneously, which has the advantages of Excellent processing efficiency, during the acupuncture process, there is no need to turn over the base fabric, which can reduce the labor intensity of workers; the second beam can be opened and closed, which can meet the processing requirements for wide-width blankets and belts.

Description

technical field [0001] The invention belongs to the technical field of non-woven machinery, and in particular relates to a jointless industrial wool needling machine with four-needle zone needling. 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...

Problems solved by technology

At present, the process of obtaining a papermaking felt or conveyor belt with a narrow width such as a width of 2 meters to 3 meters is: use a traditional acupuncture machine to perform acupuncture according to the process requirements (gram weight), and obtain a long strip with two corresponding ends. Products, and then use equipment such as industrial sewing machines to join the ends, so the joints are not smooth and uneven, even the best craftsmanship cannot meet the requirements of seamless butt joints, or there are obvious seams, Or there are overlapped crossing areas, this kind of blanket is used as a papermaking blanket, which can only meet the production requirements of low-grade paper products; used as a conveyor belt, it can only be used in occasions with lower process requirements

[0004] The non-joint industrial needlelooms with simple structure mainly include gantry type needlelooms with single / double needle area. The details can be understood from Figure 8 given by the applicant, which is for the double needle area. Yes, the so-called double-needle area refers to a jointless industrial wool needleloom with a pair of first and second needling mechanisms 1 and 2 arranged in parallel, that is, there are two needling areas, which are needled with a single-needle area. Compared with the production capacity, it has made a little progress, but there are three substantive problems in the following aspects: First, 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 In the process of turning over blankets and belts, the blankets and belts are easily damaged, and the actions of turning over blankets and belts are all done manually by workers, which is labor-intensive and inefficient; It is a hinge support, and the other end is a pin support 4 (also known as a positioning pin support). One end is hoisted with the lifting chain 5 arranged on the gantry frame 8, then the latch 6 is pulled out of the latch support 4, and then the base cloth 7 is put on or dropped off half of the blanket or belt, and then the latch 6 is inserted into the latch support 4, remove the suspension chain 5, put on the base cloth 7 at last or drop (take off) the other half of the blanket and belt, so the operation process is very cumbersome

Moreover, the processable width of the acupuncture machine with this structure is restricted, only about 4m; thirdly, the structure is characterized by double-needle area acupuncture, which cannot meet the requirements for simultaneous acupuncture on the front and back of the blanket and belt. , so the processing efficiency is relatively low

[0005] 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. Because of the rising trend, and the wider the door width, the higher the price per kilogram of products, which restricts the development of my country's paper industry to a certain extent and makes paper companies form a cost burden, eventually causing high paper prices and causing consumption pressure
