Joint-free industrial felt needle machine

Abstract

The utility model relates to a non-joint industrial wool needle loom, which belongs to the technical field of non-woven machinery. Comprising a frame with a bottom beam and an outer acupuncture mechanism for needle-punching one side of the non-woven fiber base cloth on the first beam of the frame and a corresponding needle punching mechanism on the second beam of the frame The inner needle punching mechanism for needle punching the other side of the non-woven fiber base cloth under the outer needle punching mechanism, one end of the second beam is pivotally connected to one side of the frame, and the other end of the second beam is formed as At the free end, the frame is provided with a crossbeam driving device connected with the second crossbeam on the side corresponding to the second crossbeam being pivoted, and is used to drive the second crossbeam to move, and the other side of the frame is provided with a second crossbeam. A locking device that locks or unlocks the free end of the beam. It can realize the processing of wide-width, non-joint, such as paper-making felts and conveyor belts. During the processing, there is no need to turn over the felts and belts and directly manipulate the locking device manually, which can reduce the labor intensity of workers and improve 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...

AI Technical Summary

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 non-joint industrial needlelooms with simple structure mainly include gantry type single / double needle zone needlelooms, which can be specified by the applicant. Figure 8 Understand that this figure is for the double-needle area. The so-called 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, and there are two needles. Compared with the single-needle area non-joint industrial woolen needleloom, the beam and two rows of needle beds have made some achievements in terms of production capacity, but there are two substantive problems as follows: Turn over the blanket or belt, that is, after finishing acupuncture on one side of the blanket or belt, the blanket or belt needs to be turned over in the shutdown state to complete the acupuncture on the other side of the blanket or belt. This intermittent (intermittent) The processing method constitutes an obstacle to the stability of product quality, especially in the process of turning over blankets and belts, which 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 can be seen from the shown structure that one end of the needle beam 3 should be a hinge support, and the other end should be a latch support 4 (also known as a dowel support), and the base cloth 7 is fed to the first and second acupuncture mechanisms 1 and 2. When needling, one end of the needle beam 3 must be hoisted with the chain 5 provided on the gantry 8, and then the pin 6 is pulled out of the pin support 4, and then the base cloth 7 is put on or dropped from the blanket or belt. Half, then insert the latch 6 on the latch support 4, remove the hanging chain 5, and finally put on the base cloth 7 or drop (take off) the other half of the blanket and belt, 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.
