Description

Technical Field

[0001] This invention relates to the field of jacquard ribbon weaving machine technology, specifically to a jacquard ribbon weaving machine head. Background Technology

[0002] Jacquard ribbon weaving machines are suitable for weaving various round or flat non-elastic and elastic ropes and ribbons. They are mainly used to weave various ropes and ribbons, shoelaces, elastic bands, decorative ribbons, high-tensile ribbons, fishing net lines, fishing lines, trailer ropes, marine ropes, sports belts, curtain ribbons, wires, fibers, and other high-quality products. In addition, the jacquard ribbon weaving machine adopts a computer-controlled double-acting jacquard head and uses an upper-opening needle selection system. It can be equipped with standard, enlarged, or double-knitting, medium-high-low jacquard openings. The head is installed on the central support, which is convenient for loading and unloading, and the design is simple and easy to operate.

[0003] Currently, the head drive unit of a jacquard weaving machine is used to move up and down during the jacquard process, thus extracting the warp yarns. The head drive unit typically uses two eccentric wheels to rotate, driving an external connecting arm to swing up and down. The connecting arm rests below the jacquard arm, causing the jacquard arm to rotate up and down around one end as an axis. This lever principle causes the jacquard knife to jump up and down, thereby extracting the warp yarns. Since one end of the jacquard arm is a rotating end and the other end is connected to the jacquard knife, the force of the connecting arm swinging up and down, driven by the contour trajectory of the two eccentric wheels, is sufficient to drive the jacquard arm to swing up and down, which in turn drives the jacquard knife to move up and down. As a result, the driving force consumed to drive the eccentric wheels to rotate is relatively large, leading to high power output and energy consumption of the drive components, which is not energy-efficient. Summary of the Invention

[0004] This invention addresses the technical problems existing in the prior art by providing a jacquard weaving machine head that solves the problem that, since one end of the jacquard arm is a rotating end and the other end is connected to the jacquard knife, the jacquard arm can be driven to swing up and down by the contour trajectory of two eccentric wheels, which in turn drives the jacquard knife to move up and down. This results in a large driving force used to drive the eccentric wheels to rotate, thus resulting in high power output and energy consumption of the drive components, which is not energy-efficient.

[0005] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A jacquard ribbon weaving machine head includes at least two head wall panels, which are arranged in parallel and side by side. The outer walls on both sides of each head wall panel are symmetrically arranged with respect to the central axis between the head wall panels, and a head transmission device for pulling the reciprocating motion of the yarn is provided. The head transmission device includes:

[0006] The first and second lifting arms are coaxial at one end and movably connected to the outer wall of the faucet panel.

[0007] An eccentric drive component is disposed on the lower outer wall of the faucet panel and is movably connected to one side of the first and second lifting arms. It is used to drive the first and second lifting arms to rotate alternately in the direction close to or away from the eccentric drive component, with the coaxial ends of the first and second lifting arms as the axis.

[0008] At least two jacquard mechanisms, each of which is hinged to the movable ends of the first and second lifting arms on one side along the direction of the eccentric drive member.

[0009] The cross movable component, which is movable on one side of the faucet wall panel and located above the two jacquard mechanisms, is used to connect the first lifting arm driving the jacquard mechanism below the second lifting arm to move away from the cross movable component and to connect the second lifting arm driving the jacquard mechanism below the first lifting arm to move closer to the cross movable component.

[0010] The beneficial effects of this invention are:

[0011] 1) This device utilizes an eccentric drive to drive one end of the first and second lifting arms to rotate alternately around the connecting shaft, either closer to or further away from the eccentric drive. When the first lifting arm rotates clockwise downwards, the second lifting arm rotates counterclockwise upwards. Furthermore, because the central ends of the first and second swing rods intersect and are hinged to each other on the outer side of the head arm plate, and one end of the first swing rod is hinged to one end of the first lifting arm, and the second swing rod is hinged to the second lifting arm, the two jacquard mechanisms are positioned along one side of the eccentric drive direction. The first and second lifting arms are hinged to each other at their movable ends. A cross-moving component connects the first lifting arm to the second lifting arm, causing the jacquard mechanism below the first lifting arm to move away from the cross-moving component, and the second lifting arm to the first lifting arm, causing the jacquard mechanism below the first lifting arm to move closer to the cross-moving component. At this time, the first lifting arm, rotating clockwise downwards, causes the first swing arm to rotate counterclockwise around the cross-end as its axis, and also causes the jacquard mechanism connected to it to move upwards. Simultaneously, the second lifting arm, rotating counterclockwise upwards, causes the second swing arm to rotate clockwise around the cross-end as its axis. The clockwise rotation causes the jacquard mechanism connected to it to move downwards. This allows the first lifting arm to directly drive the jacquard mechanism on the same side below to move downwards, and indirectly drive the jacquard mechanism on the other side to move upwards via the first swing arm. This causes the jacquard mechanism on the same side to drive the second swing arm to rotate clockwise. Consequently, the second swing arm tends to drive the second lifting arm to swing counterclockwise around the connecting shaft, causing the jacquard mechanism on its same side to move upwards. Conversely, the counterclockwise upward swing of the second lifting arm directly drives the jacquard mechanism on the same side below to move upwards, and indirectly drives the jacquard mechanism on the other side to move upwards via the second swing arm. The lever indirectly drives the jacquard mechanism on the other side to move downward. In addition, the jacquard mechanism on the same side drives the first swing arm to rotate counterclockwise. As a result, the first swing arm drives the first lifting arm to swing downward clockwise around the connecting shaft and drives the jacquard mechanism on the same side to move downward. This allows the jacquard mechanisms on both sides to continuously provide each other with the power to swing back and forth alternately. This reduces the driving force required for the eccentric drive to drive the first and second lifting arms to swing up and down alternately, thereby reducing the power output of the eccentric drive and effectively saving energy.

[0012] Based on the above technical solution, the present invention can be further improved as follows.

[0013] Furthermore, the cross-moving component includes a first swing arm and a second swing arm. The central ends of the first swing arm and the second swing arm cross each other and are hinged to each other on the outside of the head arm plate. One end of the first swing arm is hinged to one end of the first lifting arm, and the second swing arm is hinged to the second lifting arm.

[0014] Furthermore, the eccentric drive component includes a first connecting arm ring, a first bearing, a first synchronous pulley, an eccentric shaft, a second synchronous pulley, a second connecting arm ring, a second bearing, a drive motor, and a fixing frame.

[0015] Furthermore, the first synchronous wheel is rotatably connected to the outside of the faucet wall panel via a rotating shaft, the second synchronous wheel is located on one side of the first synchronous wheel, the first synchronous wheel is fixed off-center from the second synchronous wheel via an eccentric shaft, one output end of the drive motor is connected to the eccentric shaft, the fixing bracket is fixed on one side of the faucet wall panel and connected to the drive motor, and the first synchronous wheel and the second synchronous wheel are respectively fitted with a first bearing and a second bearing.

[0016] Furthermore, the first connecting arm ring and the second connecting arm ring are respectively sleeved on the circumferential outer walls of the first bearing and the second bearing, and the top ends of the first connecting arm ring and the second connecting arm ring are rotatably connected to the first lifting arm and the second lifting arm through rotating shafts.

[0017] The beneficial effect of adopting the above-mentioned further solution is that, by driving the first synchronous wheel to rotate through the drive motor, and since the first synchronous wheel and the second synchronous wheel are fixed off-center by an eccentric shaft, as the drive motor rotates, the first synchronous wheel and the second synchronous wheel rotate around the eccentric shaft. Utilizing the trajectory of the synchronous wheel's rotational motion contour, when the first synchronous wheel rotates from the maximum contour line at the top to the maximum contour line at the bottom in the first connecting arm ring, the second synchronous wheel rotates from the maximum contour line at the bottom to the maximum contour line at the top in the second connecting arm ring. At this moment, the first connecting arm ring on the first synchronous wheel swings downward, while the second connecting arm ring on the second synchronous wheel swings upward. Furthermore, the tops of the first and second connecting arm rings are respectively connected to the first and second lifting arms via rotating shafts, thereby driving the first lifting arm to rotate downward clockwise and the second lifting arm to rotate upward counterclockwise, respectively.

[0018] Furthermore, the jacquard mechanism includes a connecting plate, a crossbeam, and multiple jacquard knives.

[0019] Furthermore, the ends of the first and second swing arms, which are away from the eccentric drive component, are rotatably connected to connecting plates via rotating shafts. The crossbeam is rotatably connected to the bottom end of the connecting plates via rotating shafts, and a plurality of jacquard knives are arranged linearly and equally spaced on one side of the crossbeam.

[0020] Furthermore, both the first and second lifting arms have multiple rotating bolt kits arranged linearly and at equal intervals on one side of their outer surfaces. One side of the first and second lifting arms is rotatably connected to the other side of the crossbeam via the rotating bolt kits.

[0021] Furthermore, a connecting shaft is installed inside the coaxial ends of the first and second lifting arms, and the connecting shaft is rotatably connected to the faucet wall panel through a rotating shaft. Attached Figure Description

[0028] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0029] Jacquard ribbon weaving machines are suitable for weaving various round or flat non-elastic and elastic ropes and ribbons. They are mainly used to weave various ropes and ribbons, shoelaces, elastic bands, decorative ribbons, high-tensile ribbons, fishing net lines, fishing lines, trailer ropes, marine ropes, sports belts, curtain ribbons, wires, fibers, and other high-quality products. In addition, the jacquard ribbon weaving machine adopts a computer-controlled double-acting jacquard head and uses an upper-opening needle selection system. It can be equipped with standard, enlarged, or double-knitting, medium-high-low jacquard openings. The head is installed on the central support, which is convenient for loading and unloading, and the design is simple and easy to operate.

[0030] Currently, the head drive mechanism of a jacquard ribbon loom is used to move up and down during the jacquard process to extract the warp yarns. The head drive mechanism typically uses two eccentric wheels to rotate and drive an external connecting arm to swing up and down. The connecting arm rests below the jacquard arm, causing the jacquard arm to rotate up and down around one end as an axis. This lever principle causes the jacquard knife to jump up and down, thereby extracting the warp yarns. Since one end of the jacquard arm is a rotating end and the other end is connected to the jacquard knife, the force of the connecting arm swinging up and down, driven by the contour trajectory of the two eccentric wheels, is sufficient to drive the jacquard arm to swing up and down, thus driving the jacquard knife to move up and down. As a result, the driving force consumed to drive the eccentric wheels to rotate is relatively large, leading to high power output and energy consumption of the drive component, which is not energy-efficient. To address this issue, the inventor has proposed a new head drive mechanism for jacquard ribbon looms to solve the above problems.

[0031] The present invention provides the following preferred embodiments.

[0032] like Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, a jacquard ribbon loom head includes at least two head wall panels 10, which are arranged in parallel. Each of the outer walls of the head wall panels 10 is mirror-symmetrically arranged with respect to the central axis between the head wall panels 10, and a head drive device 20 for pulling the yarn in a reciprocating motion is provided. The head drive device 20 includes:

[0033] The first knife-lifting arm 202 and the second knife-lifting arm 203 are coaxial at one end and movably connected to the outer wall of the faucet wall panel 10.

[0034] An eccentric drive component 201 is disposed on the lower outer wall of the faucet wall panel 10 and is movably connected to one side of the first knife lifting arm 202 and the second knife lifting arm 203. It is used to drive the first knife lifting arm 202 and the second knife lifting arm 203 to rotate alternately in the direction close to the eccentric drive component 201 or away from the eccentric drive component 201, with the coaxial ends of the first knife lifting arm 202 and the second knife lifting arm 203 as the axis.

[0035] At least two jacquard mechanisms 206, each of which is hinged to one side of the eccentric drive member 201 at the movable end of the first lifting arm 202 and the second lifting arm 203, respectively.

[0036] The cross movable component is movable on one side of the faucet wall panel 10 and located above the two jacquard mechanisms 206. It is used to connect the jacquard mechanism 206 below the second lifting arm 203 driven by the first lifting arm 202 to move away from the cross movable component and to connect the jacquard mechanism 206 below the first lifting arm 202 driven by the second lifting arm 203 to move closer to the cross movable component.

[0037] The cross-moving components include a first swing arm 204 and a second swing arm 205. The central ends of the first swing arm 204 and the second swing arm 205 cross each other and are hinged to the outside of the faucet arm plate. One end of the first swing arm 204 is hinged to one end of the first lifting arm 202, and the second swing arm 205 is hinged to the second lifting arm 203. A connecting shaft 207 is installed inside the coaxial central ends of the first lifting arm 202 and the second lifting arm 203, and the connecting shaft 207 is rotatably connected to the faucet wall plate 10 through a rotating shaft.

[0038] The eccentric drive 201 drives one end of the first lifting arm 202 and the second lifting arm 203 to rotate alternately around the connecting shaft 207 in a direction close to or away from the eccentric drive 201. (The rotation directions described below are based on the appendix to the instruction manual.) Figure 3(Positional relationship) When the first lifting arm 202 rotates clockwise downwards, the second lifting arm 203 rotates counterclockwise upwards. Since the central ends of the first swing rod 204 and the second swing rod 205 intersect and are hinged to each other on the outside of the head arm plate, and one end of the first swing rod 204 is hinged to one end of the first lifting arm 202, and the second swing rod 205 is hinged to the second lifting arm 203, the two jacquard mechanisms 206 are respectively hinged to the movable ends of the first lifting arm 202 and the second lifting arm 203 on one side along the direction of the eccentric drive member 201. The intersecting movable member connects the first lifting arm 202 to drive the second lifting arm. The jacquard mechanism 206 below 203 moves away from the cross-moving member, and the second lifting arm 203 drives the jacquard mechanism 206 below the first lifting arm 202 to move closer to the cross-moving member. At this time, the first lifting arm 202, which rotates clockwise downwards, drives the first rocker arm 204 to rotate counterclockwise around the cross end as the axis, and drives the jacquard mechanism 206 connected to it to move upwards. At this moment, the second lifting arm 203, which rotates counterclockwise upwards, drives the second rocker arm 205 to rotate clockwise around the cross end as the axis, and drives the jacquard mechanism 206 connected to it to move downwards, enabling the first lifting arm 202 to move downwards. Arm 202 directly drives the jacquard mechanism 206 on the same side below to move downwards and indirectly drives the jacquard mechanism 206 on the other side to move upwards through the first swing rod 204. This causes the jacquard mechanism 206 on the same side to drive the second swing rod 205 to rotate clockwise. As a result, the second swing rod 205 drives the second lifting arm 203 to swing upwards counterclockwise around the connecting shaft 207, which in turn drives the jacquard mechanism 206 on the same side to move upwards. Conversely, the counterclockwise upward swinging second lifting arm 203 directly drives the jacquard mechanism 206 on the same side below to move upwards and indirectly drives the jacquard mechanism 206 on the other side through the second swing rod 205. 06. The jacquard mechanism 206 on the same side moves downward. In addition, the jacquard mechanism 206 on the same side drives the first swing arm 204 to rotate counterclockwise. As a result, the first swing arm 204 drives the first lifting arm 202 to swing clockwise downward around the connecting shaft 207 and drives the jacquard mechanism 206 on the same side to move downward. This allows the jacquard mechanisms 206 on both sides to continuously provide each other with the power to swing back and forth. This reduces the driving force of the eccentric drive 201 to drive the first lifting arm 202 and the second lifting arm 203 to swing up and down alternately, thereby reducing the power output of the eccentric drive 201 and effectively saving energy.

[0039] In this embodiment, as Figure 1 , Figure 2 , Figure 3 as well as Figure 4As shown, the eccentric drive component 201 includes a first connecting arm ring 2011, a first bearing 2012, a first synchronous pulley 2013, an eccentric shaft 2014, a second synchronous pulley 2015, a second connecting arm ring 2016, a second bearing 2017, a drive motor 2018, and a fixing frame 2019. The first synchronous pulley 2013 is rotatably connected to the outside of the faucet wall panel 10 via a rotating shaft. The second synchronous pulley 2015 is located on one side of the first synchronous pulley 2013. The first synchronous pulley 2013 is offset from the axis between the eccentric shaft 2014 and the second synchronous pulley 2015. Fixed, one output end of the drive motor 2018 is connected to the eccentric shaft 2014, the fixing bracket 2019 is fixed to one side of the faucet wall panel 10 and connected to the drive motor 2018, the first synchronous pulley 2013 and the second synchronous pulley 2015 are respectively fitted with a first bearing 2012 and a second bearing 2017, the first connecting arm ring 2011 and the second connecting arm ring 2016 are respectively fitted on the circumferential outer walls of the first bearing 2012 and the second bearing 2017, the top ends of the first connecting arm ring 2011 and the second connecting arm ring 2016 are respectively connected to the first bearing 2014 via a rotating shaft. The first lifting arm 202 is rotatably connected to the second lifting arm 203. A drive motor 2018 drives the first synchronous pulley 2013 to rotate. Since the first synchronous pulley 2013 and the second synchronous pulley 2015 are fixed off-center via an eccentric shaft 2014, as the drive motor 2018 rotates, the first synchronous pulley 2013 and the second synchronous pulley 2015 rotate around the eccentric shaft 2014. Utilizing the trajectory of the synchronous pulley rotation, when the first synchronous pulley 2013 rotates within the first connecting arm ring 2011 from the maximum contour line directly above to the maximum contour line directly below... At this time, the second synchronous wheel 2015 rotates in the second connecting arm ring 2016 from the maximum contour line directly below to the maximum contour line directly above. At this moment, the first connecting arm ring 2011 on the first synchronous wheel 2013 swings downward, while the second connecting arm ring 2016 on the second synchronous wheel 2015 swings upward. The top ends of the first connecting arm ring 2011 and the second connecting arm ring 2016 are respectively connected to the first lifting arm 202 and the second lifting arm 203 through the rotating shaft, thereby driving the first lifting arm 202 to rotate downward and the second lifting arm 203 to rotate upward respectively.

[0040] In this embodiment, as Figure 1 , Figure 2 , Figure 3 as well as Figure 4As shown, the jacquard mechanism 206 includes a connecting plate 2061, a crossbeam 2062, and a plurality of jacquard knives 2063. The ends of the first swing arm 204 and the second swing arm 205 in the direction away from the eccentric drive member 201 are rotatably connected to the connecting plate 2061 via a rotating shaft. The crossbeam 2062 is rotatably connected to the bottom end of the connecting plate 2061 via a rotating shaft. The plurality of jacquard knives 2063 are arranged linearly and equally spaced on one side of the crossbeam 2062. Since the first knife-lifting arm 202 and the second knife-lifting arm 203 are each provided with a plurality of rotating bolt assemblies 30 arranged linearly and equally spaced on one side of their outer sides, the rotation of the rotating bolts on the first knife-lifting arm 202 and the second knife-lifting arm 203 in the direction close to the connecting shaft 207 can be adjusted. The bolt assembly 30 (the rotating bolt assembly is existing technology and will not be described in detail here) is connected to the crossbeam 2062, which allows the crossbeam 2062 to gradually tilt towards the eccentric drive component 201. This causes the multiple jacquard knives 2063 located below the crossbeam 2062 to have a tilt angle that is lower on the left and higher on the right. Therefore, the horizontal height of the shed connected to the jacquard knives 2063 can also have a tilt angle that is lower on the left and higher on the right. After the warp jacquard thread passes through the lower rope with a hook below the shed, the horizontal height of the warp jacquard thread also has a tilt angle that is lower on the left and higher on the right, so that it will not be stuck by the tail needle on the braiding machine (since the height of the shed on the existing shed is at a parallel height, the warp thread passing through the shed can easily contact the tail needle below).

[0041] The specific working process of this invention is as follows:

[0042] (1) The first lifting arm 202 drives the jacquard mechanism 206 on the same side to move downward.

[0043] First, the drive motor 2018 drives the first synchronous pulley 2013 to rotate. Since the first synchronous pulley 2013 and the second synchronous pulley 2015 are fixed off-center by an eccentric shaft 2014, as the drive motor 2018 rotates, the first synchronous pulley 2013 and the second synchronous pulley 2015 rotate around the eccentric shaft 2014. Utilizing the trajectory of the synchronous pulley rotation, when the first synchronous pulley 2013 rotates within the first connecting arm ring 2011 from the maximum contour line directly above to the maximum contour line directly below, at this moment, the first... The first connecting arm ring 2011 on the synchronous pulley 2013 swings downward. The top ends of the first connecting arm ring 2011 and the second connecting arm ring 2016 are respectively connected to the first lifting arm 202 and the second lifting arm 203 through the rotating shaft. This causes the first lifting arm 202 to rotate downward. The first lifting arm 202 then causes the jacquard mechanism 206 on the same side below to move downward. At the same time, the downward-moving jacquard mechanism 206 causes the second swing rod 205 to rotate clockwise, causing the second swing rod 205 to drive the second lifting arm 203 to swing upward counterclockwise.

[0044] (2) The second lifting arm 203 drives the jacquard mechanism 206 on the same side to move upward.

[0045] When the first synchronous wheel 2013 rotates in the first connecting arm ring 2011 from the maximum outline at the top to the maximum outline at the bottom, the second synchronous wheel 2015 rotates in the second connecting arm ring 2016 from the maximum outline at the bottom to the maximum outline at the top. This causes the second lifting arm 203 to rotate downwards, and the second swing arm 205 to swing the second lifting arm 203 upwards counterclockwise. The upward displacement of the second lifting arm 203 can drive the jacquard mechanism 206 on the same side to move upwards, and drive the first swing arm 204 to rotate counterclockwise. That is, the lever arm of the first swing arm 204 transmits the force to the first lifting arm 202 to swing downwards clockwise.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
