Problems solved by technology

[0004] On the traditional medium-low speed needle loom, the needles reciprocate vertically along with the needle beam. When the needles pierce the web, the web is hooked by the needles. Accelerates to the output speed instantaneously, which causes the draft and twist of the fiber web, and then affects the quality of non-woven products

Embodiment Construction

[0016] Such as figure 1 , 2 As shown, an elliptical track acupuncture mechanism includes a main shaft 1 and a push rod 2, the main shaft 1 is connected to the connecting rod 4 through the eccentric wheel 3, the connecting rod 4 is connected to the push rod 2, and the acupuncture mechanism also includes a cylinder The cam 5 and the guide sleeve 6, and the follower 7 in the guide groove 13 of the cylindrical cam 5 are connected with the guide sleeve 6 through the double sleeve connecting plate 12.

[0017] The drive of the cylindrical cam 5 is realized through the transmission chain from the main shaft 1. The specific method is: the main shaft 1 transmits the rotary motion to the synchronous pulley 10 through the synchronous belt 11, and then to the auxiliary shaft 8, and the auxiliary shaft 8 passes through A pair of bevel gears transmits the rotary motion to the cylindrical cam 5 . Finally, the cylindrical cam 5 controls the follower 7 to realize predetermined movement throu...

Abstract

The invention discloses an elliptical track acupuncture mechanism, comprising a main shaft (1) and a push rod (2), the main shaft (1) is connected with a connecting rod (4) through an eccentric wheel (3), and the connecting rod (4) is connected with a connecting rod (4). The push rod (2) is connected, and the acupuncture mechanism also includes a cylindrical cam (5) and a guide sleeve (6), and the follower (7) and the guide sleeve (6) in the guide groove (13) of the cylindrical cam (5) Connection, the present invention is compact in structure, reliable in operation, and can realize elliptical trajectory. The drafting and twisting problems of the fiber web are solved, thereby improving the quality of non-woven products. The invention can make the spindle box consistent with the design of the spindle box of the current common acupuncture machine, which ensures that the design and manufacture of the high-speed acupuncture machine can maintain the technical inheritance with the traditional acupuncture machine.

Description

technical field [0001] The invention relates to an acupuncture mechanism, in particular to an acupuncture mechanism capable of realizing an elliptical trajectory, and belongs to the technical field of acupuncture machines. Background technique [0002] With the development of non-woven fabric production technology, higher requirements are put forward for the quality and production efficiency of non-woven fabric products. [0003] As a key equipment in the non-woven fabric production line, the needling machine is used to penetrate the fiber bundles into the fiber web through the needles, so that the friction between the fibers in the fiber web increases, and the strength of the fiber web increases. The increased density makes the fibers entangle with each other, and finally forms a non-woven fabric product with certain strength, density, elasticity and other properties. [0004] On the traditional medium-low speed needle loom, the needles reciprocate vertically along with th...
