Technical Field

The invention relates to the technical field of carpet embroidering machines, in particular to an automatic wire feeding device of a computer carpet embroidering machine.

Background

The gun-punched carpet is woven by inserting pile yarns into a carpet base fabric through steel needles to form various patterns and designs. In the weaving process, the carpet thread with a certain length which penetrates into the main shaft motor is inserted into the carpet base cloth by the bayonet head controlled by the main shaft motor and is left on the carpet to form fluff. While the carpet is continuously tufted, it is necessary to continuously supply carpet yarn to the bayonet head.

The existing common carpet gun-punching machine directly penetrates a carpet wire on a wire coil into a threading hole of a machine head cloth threading needle through a pipe, the cloth threading needle drives the carpet wire to be penetrated into a carpet backing fabric, a wire pushing needle pulls the carpet wire and pushes the carpet wire to the other side of the backing fabric through a backing fabric hole pierced by the cloth threading needle, the cloth threading needle and the wire pushing needle sequentially withdraw from the carpet backing fabric, and the carpet backing fabric clamps the carpet wire tightly to finish a needle step. The above actions are repeated continuously until the carpet is manufactured. In this process, the carpet wire is continuously taken out of the carpet wire reel.

However, the difference in length of the carpet thread caused by the thickness and the thinness of the carpet thread, the adhesion of the fluff on the thread surface and the elasticity of the thread material causes the high and low thread condition on the carpet surface. When the bayonet head works at a low rotating speed, the situation is not obvious, but with the continuous increase of the operating speed of the bayonet head, the difference between the brought-out thread quantity and the actual thread quantity is larger and larger, thereby seriously affecting the product quality.

Chinese patent No. CN 207313899U discloses a synchronous thread feeding device for a gun-pricking carpet machine, in which a driving motor is used to drive two thread feeding rollers and a main shaft motor to rotate synchronously, and a carpet thread passes through between the two thread feeding rollers and enters a pricking gun to continuously feed the pricking gun. However, the tension of the wire is low during the wire feeding process of the wire feeding roller, and the wire is easily wound.

Chinese patent application publication No. CN 111441143 a discloses a stable thread feeding and tightening device for a carpet gun-pricking machine, which adopts a rotary motor to drive two thread feeding rollers which are parallel to each other and located on the same horizontal plane, and utilizes the friction force between the two thread feeding rollers to tighten the thread in the thread feeding process by matching the first thread feeding roller and the second thread feeding roller, and a thread arranging assembly is arranged between the first thread feeding roller and the second thread feeding roller to avoid knotting and mutual winding in the thread feeding process.

The two technical schemes can improve the tension and the thread feeding of the carpet gun-punching machine to a certain extent. However, in the actual production process, some problems still remain to be solved. Because the carpet weaving process is required by patterns and processes, the gun-needling speed cannot be kept constant, when the weaving patterns have curves, corners and other conditions, in order to ensure stable mechanical motion and uniform needle steps, the rotating speed of a spindle motor needs to be repeatedly lifted, the thread output quantity provided by a driving motor of an external thread feeding mechanism cannot completely follow the thread consumption quantity required by a needle gun, and thus, more threads can be fed, the threads can be automatically coiled, if less threads are fed, the threads can fall off, and the flocking height on the surface of the carpet is different. Excessive thread feeding can also lead to the accumulation of carpet threads, and over-tightening can lead to the thread dropping of a cloth threading needle and the machine is stopped by mechanical alarm.

On the other hand, because the carpet weaving needs to be performed according to the needs of the patterns and the processes, two or more kinds of wires are often used, and each wire is separately separated from the wire coil before reaching the cloth threading needle and needs to pass through different wire feeding devices respectively. However, the surface smoothness, ductility and thickness of different wires are different, and as a result, the wires are driven only by the surface friction of the wire feeding roller, and the different wire materials have different material properties, so that the lengths of the wires driven by the same friction of the wire feeding roller are different, which also becomes a cause of different flocking levels on the surface of the woven carpet.

The existence of these problems seriously affects the production efficiency and the product quality of the gun-felted carpet machine.

Furthermore, the vertical distance between the center of the 2 nd positioning magnet 8-4 and the connecting line between the axis of the wire pressing buckle 8-1 hinge shaft and the center of the 1 st positioning magnet 8-3 is 2-3 mm.

Furthermore, the lower tool nose of the wire pressing buckle 8-1 applies 8-12N pressure to the contact position of the lower tool nose and the lower wire platform 8-2.

The working process of the automatic wire feeding device of the computer gun-felted carpet machine is as follows:

before the carpet gun-punching machine is started, a carpet wire 4-2 is pulled out of a carpet wire coil 4-1, penetrates through a gun fixing frame 3-1 and a gun transmission seat 1, enters a channel formed by a wire feeding device 8 and a limiting side plate 8-6, and penetrates through a contact part between a tool nose at the lower part of a wire pressing buckle 8-1 and the upper surface of a lower wire platform 8-2 and then penetrates through a cloth threading needle 6-2. Because the 1 st positioning magnet 8-3 and the 2 nd positioning magnet 8-4 are opposite in homopolar, the generated repulsion force enables the 2 nd positioning magnet 8-4 to drive the lower part of the wire pressing buckle 8-1 to swing anticlockwise around the hinge shaft, the lower cutter point of the wire pressing buckle 8-1 is tightly attached to the upper surface of the lower wire platform 8-2 due to the limitation of the upper surface of the lower wire platform 8-2, and as a result, the carpet wire 4-2 which passes through the space between the lower cutter point of the wire pressing buckle 8-1 and the upper surface of the lower wire platform 8-2 is pressed by the lower cutter point of the wire pressing buckle 8-1, so that the carpet wire 4-2 is pulled forwards and sent out only when moving forwards along with the cloth penetrating needle sliding block 6, and the carpet wire 4-2 is still when the cloth penetrating needle sliding block 6 retreats.

When the carpet gun-punching machine works, the output shaft of the spindle motor 2 drives the rotating shaft 1-1 of the needle gun to rotate, the rotating shaft 1-1 of the needle gun drives the cloth penetrating needle connecting rod 6-1 and the thread pushing needle connecting rod 7-1 to move, and respectively pushes the cloth penetrating needle sliding block 6 and the thread pushing needle sliding block 7 to do reciprocating linear motion. The cloth penetrating needle 6-2 fixed on the cloth penetrating needle sliding block 6 and the thread pushing needle 7-2 fixed on the thread pushing needle sliding block 7 also move synchronously with the connected sliding blocks. The cloth penetrating needle 6-2 firstly penetrates the carpet backing cloth with the carpet thread 4-2 to enable the warp and weft threads of the backing cloth to shift to form holes, the thread pushing needle 7-2 sends the carpet thread 4-2 to the other side of the backing cloth through the holes of the backing cloth penetrated by the cloth penetrating needle 6-2, the cloth penetrating needle 6-2 and the thread pushing needle 7-2 successively withdraw from the carpet backing cloth, the warp and weft threads of the carpet backing cloth can be reset physiologically and clamp the carpet thread 4-2, and a needle step is completed. The above-mentioned action process is repeated continuously until the carpet is made.

When the cloth threading needle slide block 6 slides forwards, the wire feeding device 8 is driven to move forwards, and the carpet wire 4-2 pressed by the lower end part of the wire pressing buckle 8-1 is also pulled out from the carpet wire coil 4-1. When the cloth threading needle slide block 6 slides to the foremost end of the stroke, the cloth threading needle slide block 6 starts to slide backwards, meanwhile, the thread pushing needle slide block 7 starts to slide forwards, when the cloth threading needle 6-2 is intersected with the thread pushing needle 7-2, the carpet thread 4-2 is pushed forwards by the thread pushing needle 7-2 and pulled, the carpet thread 4-2 is stressed tightly, and the lower part of the thread pressing buckle 8-1 can be lifted and pulled smoothly. In the whole action process, the carpet wire 4-2 is always kept in a tensioned state by overcoming a constant resistance, so that the wire supply quantity and the actual wire consumption quantity are completely synchronous and equal.
