Shearing device of round reversely-wrapped towel knitting machine

Abstract

The invention discloses a shearing device of a round reversely-wrapped towel knitting machine, comprising a lower looping yarn-hooking knife which is vertically located on a lower cylinder and can move up and down, and horizontal fixed yarn-cutting knifes which are located on a board of health; a groove used for hooking and pulling a pile is molded at the upper end of the lower looping yarn-hooking knife; a convex bending part is respectively molded on the yarn-cutting knifes; the lower looping yarn-hooking knife is located between two adjacent yarn-cutting knifes, moreover the bending parts on the yarn-cutting knifes which are located at the two sides of the lower looping yarn-hooking knife are respectively jointed on the side surface of the lower looping yarn-hooking knife; and along with the movement of the lower looping yarn-hooking knife, the bending parts form tangency with the lower looping yarn-hooking knife, thereby being capable of shearing the pile loop. The shearing device of the round reversely-wrapped towel knitting machine can lead the pile loop of a knitted reversely-wrapped towel to have the same length as a sheared yarn and finish the pile loop knitting and shearing operations simultaneously, reduce losses and increase interest.

Description

Technical field: [0001] The invention relates to the technical field of towel knitting machines, in particular to a shearing device of a circular turn-up towel knitting machine. The shearing device can simultaneously complete looping and shearing operations of knitted towels, thereby improving production efficiency and reducing loss. Background technique: [0002] The shearing operation of general terry cloth is usually as follows: first, knitting terry cloth on a circular knitting terry knitting machine, and then placing the cloth on another shearing machine for shearing operation. This mode of operation is not only troublesome, but also inefficient. In addition, during the shearing process, when cutting the loop part, it is difficult to ensure that the trimmed edges of the loop are neat, and multiple trimmings are required, resulting in a reduction in production efficiency. [0003] For this, someone has proposed a kind of equipment that knitted terry cloth and shearing f...

Problems solved by technology

See the Taiwan New Patent of China whose notification number is 208294, which adopts the following technical scheme: an inclined-plane blade is arranged below the groove of the raising needle, and when a new terry is knitted by the rising needle and the hook yarn of the knitting needle, utilize its The blade cuts off the old loops under the groove to achieve the purpose of shearing. Although this method can achieve the effect of shearing, but due to the toughness of the yarn, the blade is prone to wear and tear during operation, and cannot be used for a long time. , must be replaced frequently, increasing the production cost
