Weft yarn tension device with adjustable rapier machine

Abstract

The invention discloses a rapier machine weft yarn tensioner with adjustment, which comprises a base, two groups of support plates symmetrically distributed are arranged on the upper side of the base, a housing is provided at the middle position of the support plates, and the housing is The two sides of the body are provided with end covers, and the upper side of the U-shaped rib is provided with a first fastening bolt, and the U-shaped rib is connected to the square joint through the first fastening bolt, and the inside of the shell is close to One side of the through groove is provided with two sets of fixed bosses symmetrically distributed, one side of the fixed boss is connected to one end of the spring fixed slide rail, and the outer side of the spring fixed slide rail is provided with a spring, which is fixed by the spring and the spring. The use of slide rails can keep the tension stable. The second set bolt on the side of the needle seat can easily replace and disassemble the carding needle. The needle groove on the side of the base close to the carding needle can stop Protecting the carding needles during work can improve work efficiency.

Description

technical field [0001] The invention relates to the technical field of a rapier machine weft yarn tensioner, in particular to a rapier machine weft yarn tensioner with adjustment. Background technique [0002] Existing rapier machines are usually equipped with a tensioner to control the weft insertion tension to complete weaving. However, when the weft yarn passes through the tensioner nip, the nip will gradually expand, causing the nip tension to decrease. , affects the weaving output and the efficiency of opening the table, and when the machine stops working, external environmental factors may cause the comb teeth to break, resulting in the failure of the rapier machine to work normally and affecting work efficiency. At the same time, replace the comb teeth after the comb teeth break The teeth are inconvenient, which reduces the service life of the rapier machine. For example, the patent application publication number 201621012806.3 discloses a weft yarn tensioner with adj...

[0002] Existing rapier machines are usually equipped with a tensioner to control the weft insertion tension to complete weaving. However, when the weft yarn passes through the tensioner nip, the nip will gradually expand, causing the nip tension to decrease. , affects the weaving output and the efficiency of opening the table, and when the machine stops working, external environmental factors may cause the comb teeth to break, resulting in the failure of the rapier machine to work normally and affecting work efficiency. At the same time, replace the comb teeth after the comb teeth break The teeth are inconvenient, which reduces the service life of the rapier machine. For example, the patent application publication number 201621012806.3 discloses a weft yarn tensioner with adjustment for the rapier machine. Block, the block is made up of a number of components clamped head to tail. The component is cylindrical. One end of the component is provided with a connecting shaft and a limit rod. The connecting holes match each other, and the connecting shaft can rotate relative to the connecting hole, and the limit rod and the arc-shaped groove match each other. However, during the use of the above patents, the tension cannot be kept stable, and the carding needle cannot be replaced, disassembled and repaired conveniently.
