Description

Technical Field

[0001] The invention relates to the technical field of textile equipment, in particular to a triangular needle selection mountain plate structure without a motor-driven needle pusher. Background Art

[0002] The triangular needle pusher is a key component in the computerized flat knitting machine for pushing the needles for knitting. It uses a triangular design and a needle pusher mechanism to achieve precise movement and knitting action of the needles, thereby completing various complex knitting patterns and textures.

[0003] In the existing weaving process of the computer flat knitting machine, the triangular needle pusher mountain plate uses the pushing action of the triangular component to move the knitting needle up and down in the needle groove to complete the weaving action. At the same time, the needle pusher mechanism realizes various weaving by accurately controlling the moving distance and time of the knitting needle. However, due to the need for regular maintenance and care during use to ensure its long-term stable operation, the general needle pusher triangle is controlled by a motor to extend and retract, and the motor will be damaged after long-term use, affecting the normal operation of the needle selection. In addition, the motor is expensive, and regular replacement and maintenance will increase the use cost of the equipment. For this reason, we propose a motor-free needle pusher triangular needle selection mountain plate structure to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] For example, see Figure 1-Figure 10 , the present invention provides a technical solution:

[0036] See Fig.10As shown, for the mountain board of Example 1, the function of the needle selection X902 is to push the spring needle T903 to the three positions of slide rail A101, slide rail H102, and slide rail B103. These three positions control the movement of the long needle C901. The slide rail A101 position is used for weaving and turning needles, the slide rail H102 position is used for tuck and needle connection, and the slide rail B103 position is a non-weaving position. The needle selection X902 is composed of a group of needle selection pins X4 at several different positions, which correspond to the number of needle selector blades 22 respectively, and the needle selection X902 is evenly arranged in groups. The needle selection X902 can be pushed by any one of the left needle pushing triangle 5, the middle needle pushing triangle 6 and the right needle pushing triangle 7 to push the needle pin X2 at the bottom of the needle selection X902, and the return is achieved by the return pin X3.

[0037] See Figure 4-7 As shown, the needle selector 2 is roughly composed of a needle selector seat 21, a needle selector blade 22, a rotating shaft 23, and internal electronic components. The needle selector blade 22, the rotating shaft 23 and the electronic components are all installed in the needle selector seat 21. The needle selector seat 21 is installed on the base plate 1, so that the needle selector blade 22 protrudes from the base plate surface. The needle selector blade 22 is arranged on the top of the rotating shaft 23, so that the needle selector blade 22 can be controlled by the rotating shaft 23 and the electronic components to achieve the working state and the avoidance state. The needle selector blade 22 is provided with two needle pressing points 221, which respectively cooperate with the needle pressing action when the machine head moves to the left and right. The needle selector 2 has two left-right symmetrical systems to control the needle pressing action when the machine head moves to the left and right respectively.

[0038] See Figure 1 As shown, the needle selection mountain plate structure with a motor-free needle pushing triangle is shown, and the main parts of the needle selection triangle are the base plate 1, the needle selector 2, the side needle lifting triangle 3, the middle needle lifting triangle 4, the left needle pushing triangle 5, the middle needle pushing triangle 6 and the right needle pushing triangle 7.

[0039] See Figure 1 As shown, when the machine head moves to the left, if the system 1 needs to knit or transfer needles, the spring needle T903 needs to be pushed to the slide rail A101 position. When the machine head moves above the selected needle X902, the selected needle X902 is lifted by the side needle lifting triangle 3. The side needle lifting triangle 3 is in the shape of an inverted triangle. The side needle lifting triangle 3 is set directly below the needle selector 2, and it can be seen Figure 8 As shown, the selected needle X902 is lifted to the working position. At this time, the needle selector blade 22 is in a avoidance state. The selected needle X902 passes through the left needle push triangle 5 and the needle push point three 53, and then is pushed by the needle push point one 51 to push the spring needle T903 to the slide rail A101 position for knitting or turning needles.

[0040] See Figure 2As shown, when the machine head moves to the left, if the system 1 needs to tuck or connect the needle, it is necessary to push the spring needle T903 to the slide rail H102 position. Before the machine head moves to the left, when the machine head moves to the right, when the machine head moves to the top of the selected needle X902, the side needle lifting triangle 3 lifts the selected needle X902, and the side needle lifting triangle 3 is in an inverted triangle shape, so that the selected needle X902 is lifted to the working position. At this time, the needle selector blade 22 is in an avoidance state. After the machine head continues to move to the right, the selected needle X902 is pushed by the left needle pushing triangle 5 and the needle pushing point 2 52 to push the spring needle T903 to the slide rail H102 position, and wait for the machine head to run out of the range of the selected needle X902 , the machine head starts to move left, and the needle selector blade 22 is in working condition during the left movement. When the machine head moves to above the selected needle X902, the side needle lifting triangle 3 lifts the selected needle X902. When lifted, since there is a gap between the two needle pressing points 221 of the needle selector blade 22, the needle selection foot X4 at the bottom of the selected needle X902 can be avoided. Since the needle selector blade 22 is in working condition, when the machine head continues to move left, the selected needle is pressed down by the needle pressing point 221 on the right side of the needle selector blade 22 and cannot be pushed by the push needle 51. The spring needle T903 continues to move along the slide rail H102, thereby realizing the tuck or needle connection.

[0041] See Figure 3 As shown, when the machine head moves to the left, if the system 1 needs to realize non-weaving, it is necessary to push the spring needle T903 to the slide rail B103 position. Before the machine head moves to the left, when the machine head moves to the right, when the machine head moves to the top of the selected needle X902, the selected needle X902 is lifted by the side needle lifting triangle 3, and the side needle lifting triangle 3 is in the shape of an inverted triangle, so that the selected needle X902 is lifted to the working position. At this time, the needle selector blade 22 is in the working state, and the selected needle X902 is pressed down by the needle pressing point 221 on the left side of the needle selector blade 22, so that it cannot be aligned with the upper needle. The same lifting or needle connecting action is performed by pushing the spring needle T903 to the slide rail H102 position by the left needle pushing triangle 5 and the needle pushing point 2 52. After the spring needle T903 is reset and is at the slide rail B103 position, the machine head then moves to the left. At this time, the needle selector blade 22 is in working condition, and the selected needle X902 is pressed down by the needle pressing point 221 on the right side of the needle selector blade 22, so that it cannot be pushed away by the needle pushing triangle 5 and the needle pushing point 1 51, so that the spring needle T903 moves along the slide rail B103 position all the time, thereby realizing non-weaving.

[0042] For example 2, please refer to Figure 11-Figure 16 , the present invention provides a technical solution:

[0043] See Figure 11-16 As shown, for the mountain board of the second embodiment, the function of the needle selection X902 is to directly push the long needle C901 into the three positions of knitting or turning needle, tuck or receiving needle, and non-knitting.

[0044] See Fig.11As shown, when the machine head moves to the left, if the system 1 needs to knit or transfer, it is necessary to push the long needle C901 to the knitting transfer position. Before the machine head moves to the left, when the machine head moves to the right, the machine head moves to the top of the selected needle X902, and the side needle lift triangle 3 lifts the selected needle X902, so that the selected needle X902 is lifted to the working position. At this time, the needle selector blade 22 is in a evasive state. After the machine head continues to move to the right, the selected needle X902 is pushed by the push triangle 8 and the push point 4 81 and moves along the needle track. When the machine head runs out of the range of the selected needle X902, the machine head starts to move to the left. When moving to the left, the selected needle X902 moves along the needle track, and pushes the long needle C901 to the knitting transfer position. After that, the machine head continues to move to the left until the long needle C901 is taken away by the knitting triangle to complete the knitting transfer action.

[0045] See Fig.12 As shown, when the machine head moves to the left, if system 1 needs to tuck or connect the needle, it is necessary to push the long needle C901 to the tuck and connect position. Before the machine head moves to the left, when the machine head moves to the right, the machine head moves to above the selected needle X902, and the side needle lifting triangle 3 lifts the selected needle X902, so that the selected needle X902 is lifted to the working position. At this time, the needle selector blade 22 is in a working state. After the machine head continues to move to the right, the selected needle X902 is pressed down by the needle pressing point 221 of the needle selector blade 22 and moves along the needle moving track. When the machine head runs out of the range of the selected needle X902, the machine head starts to move to the left. When moving to the left, the selected needle X902 moves along the needle moving track. When the selected needle X902 reaches the needle selector 2, the needle selector blade 22 is in an avoidance state, so that the selected needle X902 is pushed by the needle pushing point 81 of the needle pushing triangle 8, thereby driving the long needle C901 to enter the tuck and connect position.

[0046] See Fig.13 As shown, when the machine head moves to the left, if system 1 needs not to weave, it is necessary to push the long needle C901 to the non-weaving position. Before the machine head moves to the left, when the machine head moves to the right, the machine head moves to above the selected needle X902, and the side needle lifting triangle 3 lifts the selected needle X902, so that the selected needle X902 is lifted to the working position. At this time, the needle selector knife 22 is in a working state, and after the machine head continues to move to the right, the selected needle X902 is pressed down by the needle pressing point 221 of the needle selector blade 22 and then moves along the needle moving track. When the machine head runs out of the range of the selected needle X902, the machine head starts to move to the left. When moving to the left, the selected needle X902 moves along the needle moving track. When the selected needle X902 reaches the needle selector 2, the needle selector blade 22 is in a working state, so that the selected needle X902 is pressed down by the needle pressing point 221 on the top of the selector blade 22, and the non-weaving is completed.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
