Tufting machine

Abstract

The invention discloses a tufting machine. The tufting machine comprises a base-cloth output roll, a wool-thread output roll, a tufting needle, a needle plate and a wool crocheting mechanism, wherein wool threads outputted by the wool-thread output roll are fed and connected onto the tufting needle by a thread feeding mechanism; base cloth outputted by the base-cloth output roll slides horizontally along the needle plate; the wool crocheting mechanism is arranged under the needle plate and comprises a wool crocheting knife, a knife holder and a power device for driving the knife holder to move; the wool crocheting knife is arranged and fixed on the knife holder and comprises a knife beam; the knife beam is provided with a vertical section and a horizontal section; the upper end of the vertical section bends and extends backwards to form an inverted hook part; the lower end part of the vertical section is connected with the front end part of the horizontal section, and the rear end part of the horizontal section is connected with a smooth section extending in the inclined-upward direction; and an inserting and connecting tail part bending and extending backwards is connected onto the smooth section. By adoption of the structure, the tufting machine can be used for producting loop-wool products.

Description

technical field [0001] The invention relates to a tufting machine. Background technique [0002] The tufting machine generally includes a base fabric output roller, a yarn output roller, tufting needles, a needle plate and a hooking mechanism. The wool output from the yarn output roller is fed to the tufting needles through the thread feeding mechanism. The needle plate is set Below the tufting needles, there is a corresponding gap on the needle plate for the tufting needles to pass through up and down, the base fabric output by the base fabric output roller slides horizontally along the needle plate, and the hooking mechanism is arranged on the needle plate Below, when working, the base fabric slides horizontally along the needle plate, and at the same time the tufting needles move up and down with the yarn and penetrate the base fabric. Hooking out, the described hooking mechanism usually includes a hooking knife, a knife seat and a power device for driving the movement o...

[0002] The tufting machine generally includes a base fabric output roller, a yarn output roller, tufting needles, a needle plate and a hooking mechanism. The wool output from the yarn output roller is fed to the tufting needles through the thread feeding mechanism. The needle plate is set Below the tufting needles, there is a corresponding gap on the needle plate for the tufting needles to pass through up and down, the base fabric output by the base fabric output roller slides horizontally along the needle plate, and the hooking mechanism is arranged on the needle plate Below, when working, the base fabric slides horizontally along the needle plate, and at the same time the tufting needles move up and down with the yarn and penetrate the base fabric. Hooking out, the described hooking mechanism usually includes a hooking knife, a knife seat and a power device for driving the movement of the knife seat, but the existing hooking knife 1' such as figure 1 As shown, it includes an upper horizontal side and a lower horizontal side, the front end of the upper horizontal side is bent downward to form a barb, the rear end of the upper horizontal side is connected with the front end of the lower horizontal side, and the rear end of the lower horizontal side The part is the plug-in tail, so that when hooking, the upper horizontal edge is inserted into the pile loop, and the wool is hooked through the barb part, but because the pile loop cannot be removed from the upper horizontal edge after being hooked, the hooking knife 1 ′ is a continuous reciprocating movement, that is, after hooking a pile loop, the hooking knife 1′ needs to be stretched out again to hook the next pile loop, so once the hooked pile loop cannot be released from the upper horizontal edge in time, then the It will accumulate on the hooking knife 1', so that the hooking knife 1' can no longer be hooked. In the prior art, the usual method is to set up a straight knife 2' to drive the straight knife 2' to move up and down , forming a shear with the hooking knife 1', and cutting the loops, so that the loops can be released from the hooking knife 1' in time, which is convenient for the hooking knife 1' to carry out the next hooking operation, but this will cause the current Some tufting machines can only produce cut pile products that cut the pile loops, but cannot produce loop pile products that do not cut the pile loops
