Description

Technical Field

[0001] The utility model relates to a jacquard machine component, in particular to a double-acting electronic tap device with a clear opening. Background Art

[0002] In the field of textiles, fabrics are usually woven with warp and weft. On the loom, the warp must be divided into two layers according to a certain rule, alternating to form a channel for the weft to pass through, that is, an opening. After the weft is introduced into the opening, the two layers of warp alternate up and down according to the fabric organization method to form a new opening. Repeating this process completes the weaving process of the fabric. There are usually six types of opening mechanisms: crank, eccentric, cam, multi-arm, jacquard and electronic opening to weave different types of fabrics. The existing jacquard machine is mainly composed of a transmission mechanism, an opening mechanism and a pattern control mechanism. According to the different pattern controls, it can be divided into a mechanical jacquard device and an electronic jacquard device. The electronic jacquard opening mechanism is divided into single-action type, double-action type and single-flower cylinder and double-flower cylinder. The single-action type is equipped with a set of vertical hooks and a knife holder. The knife holder rises and falls once for each rotation of the loom main shaft to form a shed; the double-action type is equipped with two sets of vertical hooks and two knife holders. Each time the loom main shaft rotates, the two knife holders rise and fall alternately to form two sheds.

[0003] The double-acting electronic jacquard opening mechanism currently on the market adopts an eccentric wheel structure. The first eccentric wheel and the second eccentric wheel rotate eccentrically on the driving shaft, and the connecting rod hinged thereon drives the swing rod to swing up and down, thereby driving the connected knife lifting shaft to make reciprocating swing motion. The knife lifting shaft swings up and down back and forth, and the opening formed always remains in a dynamic state. There is no static time during operation, and no stopping will occur. The opening is not clear enough, the application surface is narrow, and it is easy to cause yarn breakage. Utility Model Content

[0004] The purpose of the utility model is to provide a double-acting electronic faucet device with clear opening. The utility model has the characteristics of clear opening and increased effective opening time.

[0005] The technical solution of the utility model: a double-action electronic faucet device with a clear opening, including support frames installed at both ends of a rotating shaft, and a first eccentric wheel and a second eccentric wheel are fixedly connected at the two support frames on the rotating shaft; the first eccentric wheel and the second eccentric wheel are both composed of two sector-shaped portions with different radii connected by an arc-shaped transition portion, and a first swing arm abutting the circumferential surface of the first eccentric wheel and a second swing arm abutting the circumferential surface of the second eccentric wheel are rotatably connected to the support frame, and the first swing arm and the second swing arm are connected to the lifting knife via a connecting rod.

[0006] In the aforementioned double-action electronic faucet device with a clear opening, one end of the rotating shaft is provided with a driving member for driving the rotating shaft to rotate.

[0007] In the aforementioned double-action electronic faucet device with a clear opening, the support frame includes two support plates, and a mounting shaft is provided between the two support plates. One end of the first swing arm and the second swing arm are rotatably connected to the mounting shaft, and the middle parts of the first swing arm and the second swing arm are respectively in contact with the first eccentric wheel and the second eccentric wheel, and the other ends of the first swing arm and the second swing arm are rotatably connected to the lifting knife via a connecting rod.

[0008] In the aforementioned double-action electronic faucet device with a clear opening, a sliding groove is provided on the support plate for the lifting knife to move up and down.

[0009] In the aforementioned double-action electronic faucet device with a clear opening, bearings are provided on the first swing arm and the second swing arm, and the first swing arm and the second swing arm are rollingly connected to the circumferential surfaces of the first eccentric wheel and the second eccentric wheel respectively through the bearings.

[0010] In the aforementioned double-action electronic faucet device with a clear opening, the fan-shaped parts of the first eccentric wheel and the second eccentric wheel are staggered, and when the first eccentric wheel contacts the first swing arm to drive the lifting knife to move upward, the second eccentric wheel contacts the second swing arm to drive the lifting knife to move downward.

[0011] In the aforementioned double-action electronic faucet device with a clear opening, the lifting knife includes a first lifting knife, a second lifting knife and a third lifting knife which are arranged in parallel in front and back order, the second lifting knife is connected to the first swing arm, and the first lifting knife and the third lifting knife are both connected to the second swing arm.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model provides a first eccentric wheel and a second eccentric wheel which are composed of two fan-shaped parts with different diameters. When the first eccentric wheel and the second eccentric wheel rotate synchronously, the fan-shaped parts with different diameters contact the first swing arm or the second swing arm respectively, so that a scissors difference is formed between the first swing arm and the second swing arm, thereby driving the lifting knife to switch between high and low positions; thereby changing the opening of the electronic jacquard machine; when the first swing arm or the second swing arm only contacts the fan-shaped part with a small radius or a large radius, since the radius of the single fan-shaped part remains unchanged, the lifting knife position remains stationary during the contact between the fan-shaped part and the first swing arm or the second swing arm, thereby maintaining the opening position unchanged, so that there is a certain residence time after the opening, ensuring a clear opening, and thus increasing the effective opening time.

[0014] It can stay at the top or bottom according to the requirements of the fabric organization, and only moves up and down when changing the direction. It is beneficial to select the heald, expand the scope of use, increase the speed, and reduce the breakage rate of the warp yarn. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0020] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] Example:

[0022] like Figure 1-Figure 3 As shown, a double-action electronic faucet device with a clear opening includes support frames 2 installed at both ends of a rotating shaft 1, and a first eccentric wheel 31 and a second eccentric wheel 32 are fixedly connected at the two support frames 2 on the rotating shaft 1. The first eccentric wheel 31 and the second eccentric wheel 32 have the same structure, and are both composed of two sector-shaped portions 33 with different radii connected by an arc-shaped transition portion 34. A first swing arm 41 abutting against the circumference of the first eccentric wheel 31 and a second swing arm 42 abutting against the circumference of the second eccentric wheel 32 are rotatably connected to the support frame 2, and the first swing arm 41 and the second swing arm 42 are both connected to the lifting knife via a connecting rod 43.

[0023] Since the two sector parts 33 of the eccentric wheel have different diameters, when the first eccentric wheel 31 and the second eccentric wheel 32 rotate synchronously, when the sector parts 33 of different diameters contact the first swing arm 41 or the second swing arm 42 respectively, a scissor difference is formed between the first swing arm 41 and the second swing arm 42, thereby driving the lifting knife to switch between high and low positions;

[0024] Furthermore, the two sector-shaped portions 33 on the eccentric wheel are transitioned through the arc transition portion, which can avoid the swing arm from jumping when contacting the rotating eccentric wheel, thereby improving the working stability.

[0025] Specifically, when the arc-shaped transition portion 34 contacts the first swing arm 41 or the second swing arm 42, that is, the fan-shaped portions 33 of different diameters are switched to contact the swing arm, the position of the lifting knife will be changed, thereby changing the opening of the electronic jacquard machine; when the first swing arm 41 or the second swing arm 42 only contacts the fan-shaped portion 33 with a small radius or a large radius, since the radius of the single fan-shaped portion 33 remains unchanged, the position of the lifting knife remains stationary during the contact process between the fan-shaped portion 33 and the first swing arm 41 or the second swing arm 42, thereby maintaining the opening position unchanged, so that there is a certain residence time after the opening, ensuring a clear opening, thereby increasing the effective opening time.

[0026] One end of the rotating shaft 1 is provided with a driving member for driving the rotating shaft 1 to rotate. The driving member can adopt an existing driving assembly, such as a structure of a motor, a gear belt and a gear, a gear is provided on the output shaft of the motor, a gear is provided on the rotating shaft, and the two gears are connected by a gear belt, so that the rotating shaft 1 is driven to rotate by the motor.

[0027] The support frame 2 includes two support plates 21, and a mounting shaft 22 is provided between the two support plates 21 and is located above the first eccentric wheel 31 and the second eccentric wheel 32. One end of the first swing arm 41 and the second swing arm 42 are rotatably connected to the mounting shaft 22 through bearings, and the middle of the first swing arm 41 and the second swing arm 42 are respectively in contact with the first eccentric wheel 31 and the second eccentric wheel 32, and the other ends of the first swing arm 41 and the second swing arm 42 are rotatably connected to the lifting knife through a connecting rod 43. One end of the connecting rod 43 is hinged to the swing arm, and the other end of the connecting rod 43 is hinged to the lifting knife. This structure can ensure the working stability of the first swing arm 41 and the second swing arm 42.

[0028] The support plate 21 is provided with a slide groove 23 for the knife lifting to pass through and move up and down. The setting of the slide groove 23 can limit the range of movement of the knife lifting, avoid movement deviation, and improve the accuracy of the knife lifting movement.

[0029] The first swing arm 41 and the second swing arm 42 are both provided with bearings 47, and the first swing arm 41 and the second swing arm 42 are respectively connected to the circumference of the first eccentric wheel 31 and the second eccentric wheel 32 by rolling through the bearings 47. The contact between the swing arm and the eccentric wheel is smoother through the matching contact of the bearings 47, and the friction is reduced, and the movement is not easy to be stuck, thereby improving the smoothness of the opening switching.

[0030] The positions of the fan-shaped parts 33 of the first eccentric wheel 31 and the second eccentric wheel 32 are staggered up and down, and the rotating shaft 1 passes through the center of the first eccentric wheel 31 and the second eccentric wheel 32. When the first eccentric wheel 31 contacts with the first swing arm 41 to drive the knife lifting to move upward, the second eccentric wheel 32 contacts with the second swing arm 42 to drive the knife lifting to move downward. That is, when the fan-shaped part 33 of the large radius of the first eccentric wheel 31 is located at the top, the fan-shaped part 33 of the large radius of the second eccentric wheel 32 is located at the bottom, and when the fan-shaped part 33 of the large radius of the first eccentric wheel 31 is located at the bottom, the fan-shaped part 33 of the large radius of the second eccentric wheel 32 is located at the top, so that the movement direction of the knife lifting driven by the first swing arm 41 is opposite to that of the knife lifting driven by the second swing arm 42, forming an opening.

[0031] The lifting knife includes a first lifting knife 44, a second lifting knife 45 and a third lifting knife 46 which are sequentially arranged in parallel in front and back, the second lifting knife 45 is connected to the first swing arm 41, and the first lifting knife 44 and the third lifting knife 46 are both connected to the second swing arm 42. Different openings are formed between different lifting knives, so that more complex patterns can be woven.

[0032] The parts not described in detail in the present invention are prior art and thus will not be described in detail here.
