Background

Yarn cutters are used in the textile industry for cutting yarns. The patent with the application number of 201310422975.9 discloses a yarn cutter for textile machinery, which comprises a shell and a cutting rod, wherein a cutter is arranged at one end of the cutting rod, a cushion block is arranged at a position, corresponding to the cutter, of the inner wall of the shell, when an electromagnet attracts a trigger piece, the trigger piece is separated from a convex block on the cutting rod, the cutting rod is forwards pushed by a spring to impact on the cushion block, so that yarns are cut off, and then the cutting rod needs to be manually pulled back to the original position. This structure has several problems: 1. the cutter is generally made of 45# steel, so that the cutter head is durable, the cushion block must be softer than the cutter head, the cushion block is generally made of galvanized iron, the cushion block can be knocked out of a groove by the cutter after multiple times of knocking, the iron is exposed in the air after a plating layer is knocked off to cause rusting, and a large number of gaps are generated inside the groove full of rusty spots to cause difficulty in yarn cutting; 2. in practical use, the cutting rod has certain shaking due to certain looseness with the guide structure, the shaking generally has direction selectivity, so that the cutter is often not completely vertical to the cushion block, the cutter obliquely impacts the cushion block at many times, namely, one corner of the cutter impacts the cushion block firstly, the other corner of the cutter impacts on the cushion block with much smaller force or even completely without force, the point can be seen from the cutter marks with inconsistent depth on most yarn cutter cushion blocks, and the consequence is that when the position of the yarn is just far away from one corner of the cutter head impacting on the cushion block firstly, the cutter can cut the yarn; 3. the cutting rod needs to be reset manually, and the situation that an operator forgets to reset frequently occurs in actual production. Therefore, a new type of yarn cutter solving the above problems is required.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings in conjunction with the following detailed description. It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

The specific implementation mode is as follows: referring to fig. 1-4, a novel yarn cutter comprises a housing 2, two sides of the housing 2 are provided with a yarn guide opening 3, a smooth and wear-resistant yarn guide porcelain can be arranged in the yarn guide opening 3, a push-pull electromagnet 6 is arranged in the housing 2, one end, close to the yarn guide opening 3, of a core rod of the push-pull electromagnet 6 is provided with a rubber fork 5, two sides of the rubber fork 5 are provided with fork arms 51, a notch 52 is formed between the two fork arms 51, one end, far away from the push-pull electromagnet 6, of each fork arm 51 is densely provided with rubber columns 511, the length of each rubber column 511 is larger than the diameter of a yarn, a blade 4 used for cutting off the yarn is arranged at a position, opposite to the notch 52, on the inner wall of the housing 2, the blade 4 can be a flat knife or other type knife with a cutting function, and the blade of the blade faces the notch 52 when being the flat knife. And a wiring part 8 penetrating the shell 2, wherein the push-pull electromagnet 6 is electrically connected to the wiring part 8, and the wiring part 8 is used for connecting to a controller.

Further, a guiding portion 41 is arranged on one side of the blade 4 facing the notch 52, the guiding portion 41 is a gap in an isosceles trapezoid shape, and the lower bottom of the isosceles trapezoid is close to the notch 52, and the upper bottom is far away from the notch 52; the blade 4 is provided with a cutting portion 42 on one side of the guiding portion 41 far away from the notch 52, the cutting portion 42 is an isosceles triangle-shaped gap, the bottom side of the isosceles triangle is the upper bottom of the isosceles trapezoid profile of the guiding portion 41, obviously, the length of the upper bottom is greater than the diameter of the yarn, and a cutting edge 421 is provided at the position of the cutting portion 42 corresponding to two waists of the isosceles triangle. The height-to-base ratio of the cut portion 42 (the ratio of the height to the base of the isosceles triangle) is suitably large. The guide 41 is to have a relatively high finish.

Further, the width of the guide portion 41 on the side near the notch 52 is equal to the width of the blade 4 (the width in the up-down direction in fig. 2), so that the corresponding range of the guide portion 41 is maximized.

Furthermore, the extending direction of the blade 4 is parallel to the movement direction of the core rod of the push-pull electromagnet 6 and is perpendicular to the connecting line direction of the two wire guide openings 3, and the cutting effect of the structure is the best.

Further, the wiring member 8 is a PCB golden finger.

Furthermore, the inner wall of the shell 2 is also provided with a cushion pad 7 made of rubber, the cushion pad 7 corresponds to one end, far away from the rubber fork 5, of the core rod of the push-pull electromagnet 6, and the core rod can impact the cushion pad 7 when returning to the original position after cutting off, so that the buffering effect is achieved.

Further, the device further comprises a capacitor 1, wherein the capacitor 1 is electrically connected to the wiring component 8, and the capacitor 1 is connected with the push-pull type electromagnet 6 in parallel, so that the adverse effect on the power supply device is reduced.

The working principle is as follows: in normal conditions, yarns pass through the two yarn guide openings 3, and the rubber fork 5 and the blade 4 are respectively positioned at two sides of the yarns; when cutting is performed, the push-pull electromagnet 6 is operated to rapidly move the rubber fork 5 toward the blade 4, and the yarn is pushed toward the blade 4 by the rubber fork 5 (the yarn is not necessarily aligned with the blade 4), enters the cutting portion 42 along the guide portion 41, and is cut. In the process, the yarn is squeezed between the densely covered rubber columns 511, so that the two ends of the yarn are respectively fixed on the two fork arms 51, and the yarn is convenient for an operator to find. The controller (not belonging to the device) can adopt a mode of powering on the push-pull electromagnet 6 for a short time (or instantaneously), and after the power is off, the rubber fork 5 returns to the original position along with the core rod of the push-pull electromagnet 6 under the action of the spring on the push-pull electromagnet 6. Since the cutting portion 42 has an isosceles triangle shape, as shown in fig. 2, the yarn is gradually cut from the left side and from both the upper and lower directions, and thus cutting is easier.
