Abstract
Description
Technical Field
[0001] This utility model relates to the field of needle selection technology for glove machines, and in particular to a needle selection tool and a glove machine having the same. Background Technology
[0002] Computerized glove knitting machines are a type of flat knitting machine. Their basic structure consists of front and rear needle beds located between left and right bases. Movable knitting needles are positioned in the needle grooves of these needle beds. Separate front and rear cam heads have cam base plates that move laterally with the cam heads. Various cams on the base plates interact with the heels of the knitting needles (combination needles) to select, cast on, and clear needles, thus completing various knitting functions. The entire needle selection mechanism within the glove machine utilizes a needle selector plate, a needle guide plate, a needle selector shaft, and a pressure bar to select needles. Based on the position of the needle selector, the needle guide plate moves the combination needles (needle guide plate + knitting needles) to their respective positions.
[0003] However, since the needle selector heel is supported by the upward support of the needle clip, the needle clip needs to be rotated upwards by the rotating part each time a needle is selected to make room for the needle selector heel to swing. This process causes all the needle clips to protrude from the needle plate. In order to avoid interference with the cam head, the cam head needs to be moved to the outer area of the needle plate. After the needle selection is completed, it is moved to the outer area of the selected area. Even though the length of most of the needle selection areas is less than the length of the needle plate, this greatly increases the movement distance and time of the cam head during needle selection, thereby increasing the needle selection time and reducing the overall knitting efficiency. Utility Model Content
[0004] This utility model discloses a needle selection clip and a glove machine having the same. By setting a hook-shaped needle selection part on the needle selection clip, the entire clip needs to be rotated in the opposite direction each time a needle is selected, so that all the needles of the needle clip fall back into the needle plate and are in the lowest position. The cam head only needs to move to the outside of the needle selection area, which greatly reduces the distance the cam head moves and the needle selection time, and increases the knitting efficiency.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A needle selection tool includes a main plate and an elastic part, an abutting part, a pressing part and a needle selection part connected to the main plate;
[0007] The main piece has a first end and a second end. The first end is provided with a rotating hole, and the pressing part and the selection needle part are connected to the second end.
[0008] The aforementioned elastic part is used in conjunction with the pressure strip to give the aforementioned needle selection part a tendency to rotate in the forward direction;
[0009] The aforementioned abutment portion can be used in conjunction with the needle selection shaft to cause the needle selection portion to rotate in the reverse direction or to prevent the needle selection portion from rotating in the forward direction.
[0010] The needle selection part is configured as a hook-shaped structure, and the inner wall of its open end has a first stepped surface and a second stepped surface, which can be used to abut against the end of the needle selection head to prevent the needle selection part from rotating in the forward direction.
[0011] Furthermore, when the tip of the needle abuts against the first stepped surface, the needle insert is in the non-needle position.
[0012] When the tip of the needle abuts against the second step surface, the needle insert is in the low needle position.
[0013] When the tip of the needle is located outside the aforementioned needle selection section, the needle insert is positioned at the high needle position.
[0014] Preferably, the opening end of the needle selection section is oriented toward the rotating hole.
[0015] Preferably, the needle selection portion is located at the end of the pressing portion away from the main piece.
[0016] Preferably, the elastic part includes an arc-shaped strip and a pressing strip;
[0017] The aforementioned arc-shaped strip is connected to the aforementioned main piece, and the connection point with the aforementioned main piece is located on the aforementioned main piece between the aforementioned first end and the aforementioned second end, and the connection point is located on the same side of the axis of the aforementioned rotating hole as the aforementioned pressing part;
[0018] The aforementioned arc-shaped strip extends from the end away from the main piece toward the first end and extends to the outside of the first end, and connects with the aforementioned clamping strip located on the outside of the first end.
[0019] Preferably, the end of the arc-shaped strip near the main piece is provided as an arc-shaped portion, which first extends towards the second end and then extends away from the second end.
[0020] Preferably, the abutting portion includes a first connecting strip and a second connecting strip;
[0021] The first connecting strip is connected to the main piece, and the connection point with the main piece is located on the main piece between the first end and the second end, and the connection point and the needle selection part are located on the same side of the axis of the rotating hole.
[0022] The first connecting strip extends from the end away from the main piece toward the end closer to the first end, and extends to the outside of the first end, and connects with the second connecting strip.
[0023] The connection between the second connecting strip and the first connecting strip forms an obtuse angle, and the second connecting strip is positioned away from the main piece.
[0024] A glove-making machine, comprising the aforementioned needle-selecting bird piece.
[0025] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0026] The needle selection section is hook-shaped. During each needle selection, in order for the needle selection head of the needle selection plate to come into contact with the needle selection section, it must rotate in the opposite direction under the action of the needle selection shaft to bring the needle selection section to the initial position. At this time, looking at the entire needle plate, all the needle pins of the needle plates fall back into the needle plate and do not protrude from the needle plate. Then, under the action of the needle selection plate and the needle selection section, only the needle pins of the corresponding area of the needle plate will protrude to the low needle position or high needle position. Therefore, the cam head only needs to move to the outside of the area where needles need to be selected, instead of the entire needle plate of needle pins protruding during the needle selection process, requiring the cam head to move to the outside of the entire needle plate. This greatly reduces the moving distance of the cam head during needle selection, thereby further improving knitting efficiency. Attached Figure Description

[0038] This utility model embodiment provides a needle-selecting bird clip, such as Figure 1As shown, it includes a main plate 11 and an elastic part 12, an abutment part 13, a pressing part 14, and a needle selection part 15 connected to the main plate 11. The main plate 11 has a first end 111 and a second end 112. The first end 111 is provided with a rotating hole 113 for cooperating with a mounting shaft. In fact, all the main plates 11 of the bird clips 1 are mounted on the same mounting shaft. The pressing part 14 and the needle selection part 15 are connected to the second end 112 and are spaced apart from each other, located on both sides of the axis of the rotating hole 113. The needle ejector plate is placed in the space between the two. The elastic part 12 is used to cooperate with the pressure strip 2 so that the entire needle ejector plate 1 is always under force. The abutment part 13 is used to cooperate with the needle selection shaft 3 so that the entire needle ejector plate 1 is in the required position. The needle selection part 15 is used to cooperate with the needle selection head of the needle selection plate 4, and together with the pressure strip 2 and the needle selection shaft 3, the needle ejector plate 1 is fixed in the non-needle position, the low position and the high position, so that the needle ejector plate needle 5 is in the non-needle position, the low position and the high position.
[0039] In this embodiment, the elastic part 12 can be used in conjunction with the pressure strip 2 to give the needle selection part 15 a tendency to rotate in the forward direction (forward rotation here means rotation in the direction of needle selection, such as...). Figure 3 As shown), the abutment portion 13 can be used in conjunction with the needle selection shaft 3 to cause the needle selection portion 15 to rotate in the reverse direction or to prevent the needle selection portion 15 from rotating in the forward direction. The needle selection portion 15 has a hook-shaped structure, and the inner wall of the open end has a first stepped surface 151 and a second stepped surface 152. The first stepped surface 151 is higher than the second stepped surface 152, and can abut against the end of the needle selection head to prevent the needle selection portion 15 from rotating in the forward direction. Specifically, in actual use, such as... Figure 3 As shown, before needle selection, the needle selection shaft 33 has a needle disengagement baffle ( Figure 1 The dotted line position first acts on the contact part, causing the entire needle plate 1 to rotate in the opposite direction to the initial position, causing the needle selection part 15 to move in the opposite direction to the initial position. At this time, the entire needle plate 1 is in the initial position (lowest position), and the corresponding needle pin 5 is also in the initial position, that is, inside the needle plate. When selecting needles, the needle selection head of the needle selection plate 4 is rotated electromagnetically, as... Figure 3 As shown, when the needle selection head of the needle plate 4 rotates to abut against the first step surface 151, it hooks the needle selection head in the opposite direction. Under the action of the pressure bar and the needle selection shaft 33, the needle selection part 15 is fixed, and all the needle ejector pins 5 on the needle plate are located inside the needle plate (not in the needle position). When the needle selection head of the needle plate 4 rotates to abut against the second step surface 152, as... Figure 4 As shown, the needle selection head is hooked in the opposite direction, and under the action of the pressure bar and the needle selection shaft 33, the needle selection part 15 is fixed. At this time, the needle ejector plate 5 extends out of the needle plate and is in the low needle position. When the needle selection head of the needle selection plate 4 rotates to the outside of the hook-shaped space of the needle selection part 15, the needle selection shaft 33 rotates to the preset position in advance, so that the needle exit baffle of the needle selection shaft 33 abuts against the abutting part of the needle selection plate 1, as shown. Figure 5As shown, at this time, the needle selection part 15 is fixed, and the needle ejector pins 5 extend out of the needle plate and are in the high needle position. Since the needle selection part 15 is designed as a hook, each time a needle is selected, in order for the needle selection head of the needle selection plate 4 to abut against the needle selection part 15, it must be rotated in the opposite direction under the action of the needle selection shaft 3 to first make the needle selection part 15 in the initial position. At this time, looking at the entire needle plate, all the needle ejector pins 5 fall back into the needle plate and do not protrude from the needle plate. When selecting a needle again, under the action of the needle selection plate 4 and the needle selection part 15, only the needle ejector pins 5 in the corresponding area of the needle plate will protrude to the low needle position or the high needle position. Therefore, the triangular knitting head only needs to move to the outside of the area where the needle needs to be selected, and the needle ejector pins 5 of the entire needle plate will not protrude during the needle selection process. In order to avoid motion interference with the triangular knitting head, the triangular knitting head needs to move to the outside of the entire needle plate, which reduces the moving distance of the triangular knitting head during needle selection, thereby further improving production efficiency.
[0040] It should be noted that the initial position and the non-needle position of the needle selection part 15 and the needle ejector plate 5 are the same. There may be a slight deviation in reality, but it is very small and can be ignored. The difference is that the initial position of the needle ejector plate 5 is driven by the needle selection shaft 3. At this time, the non-needle ejection stop bar of the needle selection shaft 3 abuts against the abutment part 13. When the needle ejector plate 5 is in the non-needle position, the needle selection shaft 3 rotates, and the non-needle ejection stop bar no longer abuts against the abutment part 13. The needle selection head of the needle selection plate 4 abuts against the first step surface 151 and is limited.
[0041] Specifically, it is known that the needle head of the needle selection plate 4 is used in conjunction with the first step surface 151 and the second step surface 152. The first step surface 151 and the second step surface 152 are the force-bearing surfaces, such as... Figure 2 As shown, the open end of the needle selection section 15 is positioned towards the rotating hole 113, making the distance between the force-bearing surface and the surface containing the central axis of the rotating hole 113 smaller. This results in a larger torque L on the force-bearing surface, allowing a smaller force F to be applied to the stepped surface, thereby achieving needle position adjustment. Furthermore, the end of the needle selection section 15 near the second end 112 is connected by a connecting strip. Of course, in order to make the torque greater when the stepped surface of the needle selection section 15 acts on the needle selection head of the needle selection plate 4, the needle selection section 15 is positioned at the end of the pressing part 14 away from the main plate 11, further away from the rotating hole 113.
[0042] Specifically, the elastic part 12 includes an arc-shaped strip 121 and a pressing strip 122. The arc-shaped strip 121 is connected to the main piece 11, and the connection point with the main piece 11 is located on the main piece 11 between the first end 111 and the second end 112. The connection point is located on the same side of the axis of the rotating hole 113 as the pressing part 14. The end of the arc-shaped strip 121 away from the main piece 11 extends towards the first end 111 and extends to the outside of the first end 111, and connects with the pressing strip 122 located on the outside of the first end 111. This ensures the span of the entire arc-shaped strip 121 and the resilience of the elastic part 12, while also preventing the pressing strip 122 from being located too far outside the rotating hole 113, which would result in a longer overall length of the piece 1. Furthermore, the end of the arc strip 121 near the main piece 11 is set as an arc portion 1211. The arc portion 1211 first extends towards the second end 112 and then extends away from the second end 112, making the arc curvature of the arc strip 121 greater and its elastic effect after being acted upon by the pressure strip 2 better.
[0043] Specifically, the abutment portion 13 includes a first connecting strip 131 and a second connecting strip 132. The first connecting strip 131 is connected to the main piece 11, and the connection point with the main piece 11 is located on the main piece 11 between the first end 111 and the second end 112. The connection point is located on the same side of the axis of the rotating hole 113 as the needle selection portion 15. The end of the first connecting strip 131 away from the main piece 11 extends towards the first end 111 and extends to the outside of the first end 111, and connects with the second connecting strip 132. This ensures the span of the entire abutment portion 13 and avoids the second connecting strip 132 being located further outside the rotating hole 113, which would make the entire piece 1 longer and larger. Moreover, the connection between the second connecting strip 132 and the first connecting strip 131 forms an obtuse angle, and the second connecting strip 132 is set away from the main piece 11. This strengthens the overall strength of the abutment portion 13 and allows the second connecting strip 132 to have a larger elastic movement space, which is also convenient for use with the stop bar on the needle selection shaft 3.
[0044] A glove machine has the aforementioned needle selection bird plate 1. By providing a hook-shaped needle selection part 15 on the needle selection bird plate 1, the entire bird plate 1 needs to rotate downwards in the opposite direction each time a needle is selected, so that all the needles 5 of the needle plate fall back into the needle plate and are in the lowest position. The cam head only needs to move to the outside of the needle selection area, which greatly reduces the distance the cam head moves and the needle selection time, and increases the knitting efficiency.
[0045] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
