Computer-controlled servo 3D bayonet tufted carpet machine

Abstract

The invention discloses a computer-controlled servo 3D bayonet tufted carpet machine which comprises a group of front and rear racks which stand opposite to each other, wherein the front rack is provided with a cloth locking mechanism for supporting and binding the corners of carpet base cloth, and the rear rack is provided with a displacement mechanism; a tufting head is arranged on the displacement mechanism towards the front rack, and the touch surface of the tufting head involves the whole region in the front rack under the condition that the tufting head is driven by the displacement mechanism. The rack is vertically arranged and is divided into two, and the rack is flexibly arranged and is convenient to move; the whole size of the rack is not changed, but a large part of space is occupied aloft, and the landing area is smaller. Only one tufting head can move and tuft in the whole range of the carpet base cloth, and is widely suitable for various different carpet twines, the speed is relatively high, the precision is improved, the details of the original carpet pattern is shown easily, the finished carpet pattern product is lossless, and more importantly, a carpet with a stereoscopic 3D effect can also be woven.

Description

technical field [0001] The invention relates to the technical field of tufted carpet machines, in particular to a fully computerized servo 3D gun-barbed tufted carpet machine. Background technique [0002] Tufted carpet is machine-made carpet with tufted mechanical tufting on the carpet base fabric to form loop pile or cut pile carpet surface. The width of the product can reach several meters, and it is mainly used as aisle and indoor floor covering materials. [0003] At present, the tufting machines for the production of tufted carpets are all platen type, which mainly evolved from the structure of sewing machines: [0004] Such as a tabletop computer tufting machine disclosed in patent CN201220229859.6, which includes a frame, a machine head, a wire rack, a worktable, a movable frame, a driving device, a control panel and a computer host, and the worktable is set There is a track, and the movable frame is placed on the track and can reciprocate along the track. At least ...

AI Technical Summary

Problems solved by technology

[0006] However, the existing table-type tufting machines have the following defects: (1) Because the width of the tufted carpet is very wide, and because the carpet base fabric is arranged horizontally, and the tufting heads are arranged from above for tufting, the table-type tufting The machine occupies a very large area and is very inconvenient to move

(2) Also because the width of the tufted carpet is very wide, and the table-type tufting machine horizontally stretches the carpet base fabric, it will form a sag in the middle, and the bracket cannot be arranged below, otherwise it will be pushed up when the gun is stabbed, and the carpet base fabric It cannot be stretched normally, the position accuracy is not high when tufting, and the pattern is easy to be distorted

(3) The tufting head can only be tufted up and down, and cannot move anywhere on the front, back, left, and right sides of the carpet base fabric, and the displacement is completely completed by the carpet base fabric itself, so a row or a circle should be arranged on the format. The multiple tuft heads in a circle are not only expensive, but also the details of the multiple tuft heads are not in place, and the pattern is easy to be distorted.

(4) There is no carpet cutting mechanism integrated in the tufting head, so it needs to be set up separately. Such an independent secant mechanism has poor coordination consistency, which is very easy to cause the problem of cutting the thread of the incoming line
