Description

Technical Field

[0001] This utility model relates to the field of warp threading machine technology, and in particular to a clamping device and a warp threading machine. Background Technology

[0002] The threading machine is equipped with a clamping device for holding the threading rod. The clamping device usually includes a fixed plate and a movable plate. The fixed plate is provided with a first protrusion, and the movable plate is provided with a second protrusion. The movable plate can move relative to the fixed plate and move the second protrusion toward or away from the first protrusion, so that the first protrusion and the second protrusion jointly clamp the threading rod, or the first protrusion and the second protrusion jointly release the threading rod.

[0003] In related technologies, the fixing plate and the clamping plate are stacked. When the first protrusion and the second protrusion clamp the string rod, the string rod will be subjected to a first force applied by the first protrusion and a second force applied by the second protrusion. Since the first force and the second force are not in the same straight line, the first force and the second force will generate a resultant torque on the string rod, causing the string rod to produce a certain degree of sway. However, the end of the string rod is embedded in the groove of the heddle wheel. The sway generated by the string rod will cause its end to rub against the side wall of the groove, which will increase the wear of the heddle wheel. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a clamping device and a threading machine, which can reduce the sway amplitude of the threading rod caused by the clamping device when clamping the threading rod, and reduce the wear on the heddle roller.

[0005] In a first aspect, this utility model provides a clamping device, which includes a first abutting mechanism and a second abutting mechanism, the first abutting mechanism and the second abutting mechanism being movable relative to each other along a first direction;

[0006] The first abutting mechanism includes multiple first abutting units, which are spaced apart along a first direction. The second abutting mechanism includes multiple second abutting units, which are also spaced apart along the first direction. One first abutting unit corresponds to one second abutting unit, and each corresponding first and second abutting unit is used to abut against opposite sides of the connecting rod along the first direction.

[0007] The first abutting unit and the second abutting unit are opposite to each other along the first direction and are spaced apart, or the first abutting unit defines a first gap, and the second abutting unit and the first gap are opposite to each other along the first direction and are spaced apart.

[0008] The clamping device according to this utility model has at least the following technical effects:

[0009] By positioning the first and second abutting units opposite each other along a first direction, or by defining a first gap in the second abutting unit, with the first abutting unit and the gap opposite each other along the first direction and spaced apart, when the first and second abutting units abut against opposite sides of the string rod along the first direction, the first force generated by the first abutting unit and the second force generated by the second abutting unit can be on the same straight line. Alternatively, the first force generated by the second abutting unit and the first gap are opposite each other along the first direction, and the second force generated by the first abutting unit is located on both sides of the first gap. That is, the second force generated by the second abutting unit is located between the first forces generated by the first abutting unit. This facilitates the mutual cancellation of the first and second forces, thereby reducing the resultant torque generated by the first and second forces on the string rod. This reduces the sway of the string rod caused by the clamping device when clamping it, avoids increased friction between the end of the string rod and the side wall of the mounting groove of the heddle wheel due to the sway, reduces the wear of the heddle wheel, and helps to improve the service life of the heddle wheel.

[0011] The second abutment unit includes a second abutment protrusion, a first gap between the second abutment protrusion and two corresponding first abutment protrusions being opposite to each other along a first direction and spaced apart, and a second abutment side being provided on one side of the second abutment protrusion along the first direction; wherein,

[0016] The second abutting mechanism also includes a second connecting plate, which is located in the second gap, and the first abutting protrusion of each second abutting unit is respectively connected to the second connecting plate.

[0017] According to some embodiments of the present invention, the first abutting unit is provided with a first abutting side and a first pressing side on one side along the first direction. The first pressing side is located at the top of the first abutting side. The first abutting side is used to abut against one side of the string rod along the first direction, and the first pressing side is used to abut against the top side of the string rod and press the string rod; and / or,

[0018] The second abutting unit is provided with a second abutting side and a second pressing side on one side along the first direction.

[0022] According to some embodiments of the present invention, the clamping device further includes a lifting mechanism, which is connected to the first abutting mechanism and the second abutting mechanism respectively, and is used to drive the first abutting mechanism and the second abutting mechanism to move up and down.

[0046] In the description of this utility model, the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0047] like Figure 1 As shown, this utility model provides a clamping device 100 for clamping a string rod 2000.

[0048] like Figure 2 and Figure 3 As shown, the clamping device 100 includes a first abutting mechanism 10 and a second abutting mechanism 20, which are capable of moving relative to each other along a first direction X.

[0049] The first abutting mechanism 10 includes a plurality of first abutting units 11, which are spaced apart along the first direction X. The second abutting mechanism 20 includes a plurality of second abutting units 21, which are spaced apart along the first direction X. One first abutting unit 11 and one second abutting unit 21 correspond to each other. The corresponding first abutting unit 11 and second abutting unit 21 are respectively used to abut against the opposite sides of the rod 2000 along the first direction X.

[0050] Among them, such as Figure 4 As shown, the first abutting unit 11 and the second abutting unit 21 are opposite to each other along the first direction X and are spaced apart, or, as... Figure 5 As shown, the first abutting unit 11 defines a first gap 1101, and the second abutting unit 21 and the first gap 1101 are opposite to each other along the first direction X and are spaced apart.

[0051] In use, each corresponding first abutment unit 11 and second abutment unit 21 can clamp and fix a rod 2000, thereby realizing the clamping and fixing of multiple rods 2000 by the clamping device 100. Specifically, during the movement of the first abutment mechanism 10 and the second abutment mechanism 20 relative to each other along the first direction X, the corresponding first abutment unit 11 and second abutment unit 21 can move toward or away from each other to abut against opposite sides of the rod 2000 along the first direction X, thereby jointly clamping and fixing the rod 2000, or removing the abutment action on opposite sides of the rod 2000 along the first direction X, thereby jointly releasing the rod 2000.

[0052] In this embodiment of the invention, by positioning the first abutting unit 11 and the second abutting unit 21 opposite each other along the first direction X, or by defining a first gap 1101 in the second abutting unit 21, and with the first abutting unit 11 and the gap opposite each other along the first direction X and spaced apart, when the first abutting unit 11 and the second abutting unit 21 respectively abut against opposite sides of the connecting rod 2000 along the first direction X, as... Figure 4 As shown, the first force F1 generated by the first supporting unit 11 and the second force F2 generated by the second supporting unit 21 can be located on the same straight line, or, as... Figure 5As shown, the first force F2 generated by the second supporting unit 21 and the first gap 1101 are opposite each other along the first direction X. The second force F1 generated by the first supporting unit 11 is located on both sides of the first gap 1101. That is, the second force F2 generated by the second supporting unit 21 is located between the first force F1 generated by the first supporting unit 11. In this way, the first force F1 and the second force F2 can cancel each other out, so as to reduce the resultant torque generated by the first force F1 and the second force F2 on the string rod 2000. This reduces the sway of the string rod 2000 caused by the clamping device when clamping the string rod 2000, avoids the sway of the string rod 2000 causing its end to rub against the side wall of the mounting groove of the heddle wheel 200, reduces the wear of the heddle wheel 200, and helps to improve the service life of the heddle wheel 200.

[0053] like Figure 3 , Figure 5 and Figure 6 As shown, in some embodiments, the first abutting unit 11 includes two first abutting protrusions 111, which are spaced apart along the second direction Y. The two first abutting protrusions 111 define the aforementioned first gap 1101. One side of the two first abutting protrusions 111 along the first direction X is provided with a first abutting side 1111. The second direction Y intersects the first direction X. The second abutting unit 21 includes a second abutting protrusion 211. The first gap 1101 between the second abutting protrusion 211 and the corresponding two first abutting protrusions 111 is opposite to and spaced apart along the first direction X. One side of the second abutting protrusion 211 along the first direction X is provided with a second abutting side 2111.

[0054] The first abutting side 1111 and the second abutting side 2111 are respectively used to abut against the opposite sides of the rod 2000 along the first direction X.

[0055] With the above configuration, when the first supporting unit 11 and the second supporting unit 21 support each other along the first direction X and the opposite sides of the connecting rod 2000 along the first direction X, the first force F2 generated by the second supporting unit 21 and the first gap 1101 are opposite to each other along the first direction X. The second force F1 generated by the first supporting unit 11 is located on both sides of the first gap 1101. That is, the second force F2 generated by the second supporting unit 21 is located between the first force F1 generated by the first supporting unit 11. In this way, it is beneficial for the first force F1 and the second force F2 to cancel each other out, so as to reduce the resultant torque generated by the first force F1 and the second force F2 on the connecting rod 2000.

[0056] Optionally, the first direction X and the second direction Y are perpendicular.

[0057] It is understandable that the first abutting side 1111 and the rod 2000 on one side along the first direction X can be in line contact or in surface contact. Similarly, the second abutting side 2111 and the rod 2000 on the other side along the first direction X can be in line contact or in surface contact.

[0058] In some embodiments, the first abutting sides 1111 of the two first abutting protrusions 111 are flush, and the first abutting sides 1111 of the two first abutting protrusions 111 are both perpendicular to the first direction X. That is, the first abutting sides 1111 of the two first abutting protrusions 111 are located on the same plane, and the plane is perpendicular to the first direction X. Thus, when the first abutting sides 1111 of the two first abutting protrusions 111 abut against one side of the rod 2000 along the first direction X, the first abutting sides 1111 of the two first abutting protrusions 111 can both be parallel to and abut against the side of the rod 2000 along the first direction X, so as to avoid the rod 2000 from swaying when abutting against the rod 2000 due to the inconsistency of the second abutting sides 2111 of the two second abutting protrusions 211 along the first direction X.

[0059] In some embodiments, along the second direction Y, the distance between the second abutting side 2111 of the second abutting protrusion 211 and the first abutting side 1111 of the corresponding two first abutting protrusions 111 is equal. That is, on the projection plane perpendicular to the first direction X, the projection of the first abutting side 1111 of the first abutting protrusion 111 is located in the middle of the second abutting side 2111 of the corresponding two second abutting protrusions 211. With the above arrangement, when the first abutting unit 11 and the second abutting unit 21 abut against the opposite sides of the rod 2000 along the first direction X, the second force F2 generated by the second abutting side 2111 can be centered in the middle of the two first forces F1 generated by the corresponding two first abutting sides 1111. In this way, the resultant torque of the first force F1 and the second force F2 can be zero, thereby preventing the rod 2000 from swaying when the clamping device clamps the rod 2000.

[0060] In some embodiments, such as Figure 3 As shown, the first abutting mechanism 10 also includes two first connecting plates 12, which are spaced apart along the second direction Y, and a second gap 1201 is defined between the two first connecting plates 12. The two first abutting protrusions 111 of each first abutting unit 11 are respectively connected to the two first connecting plates 12. Figure 6As shown, the second abutting mechanism 20 also includes a second connecting plate 22, which is located in the second gap 1201. The first abutting protrusions 111 of each second abutting unit 21 are respectively connected to the second connecting plate 22. With the above arrangement, by driving the first connecting plate 12 and the second connecting plate 22 to move relative to each other along the first direction X, the corresponding first abutting unit 11 and second abutting unit 21 can move toward or away from each other to abut against opposite sides of the rod 2000 along the first direction X, thereby achieving joint clamping and fixing of the rod 2000. Alternatively, the abutting action on opposite sides of the rod 2000 along the first direction X can be removed, thereby achieving joint release of the rod 2000.

[0061] It is understood that the number of the first abutting protrusion 111 of the first abutting unit 11 and the second abutting protrusion 211 of the second abutting unit 21 can be set according to actual needs, and is not limited to one first abutting protrusion 111 and two second abutting protrusions 211. It is sufficient that there is at least one first abutting protrusion 111 and at least two second abutting protrusions 211, and the first gap 1101 between two adjacent second abutting protrusions 211 is provided with at least one first abutting protrusion 111 opposite to it. For example, in some other embodiments, the first abutting unit 11 has three first abutting protrusions 111, which are spaced apart along the second direction Y. The first gap 1101 is defined between each two adjacent first abutting protrusions 111, that is, there are two first gaps 1101. The second abutting unit 21 has two second abutting protrusions 211, one second abutting protrusion 211 and one first gap 1101 are opposite to each other along the first direction X and are spaced apart, and the other second abutting protrusion 211 and the other first gap 1101 are opposite to each other along the first direction X and are spaced apart.

[0062] The number of first connecting plates 12 is equal to the number of first abutting protrusions 111 of the first abutting unit 11. When there are two or more first connecting plates 12, each first connecting plate 12 is configured to move synchronously in the same direction. The number of second connecting plates 22 is equal to the number of second abutting protrusions 211 of the second abutting unit 21. When there are two or more second connecting plates 22, each second connecting plate 22 is configured to move synchronously in the same direction.

[0063] It is understood that in some other embodiments, such as Figure 4As shown, the first abutting unit 11 and the second abutting unit 21 are opposite to each other along the first direction X and are spaced apart. The first abutting unit 11 includes a first abutting protrusion 111, and a first abutting side 1111 is provided on one side of the first abutting protrusion 111 along the first direction X. The second abutting unit 21 includes a second abutting protrusion 211, and a second abutting side 2111 is provided on one side of the second abutting protrusion 211 along the first direction X. The first abutting side 1111 and the second abutting side 2111 are opposite to each other along the first direction X and are spaced apart.

[0064] It is understood that the number of the first abutting protrusion 111 of the first abutting unit 11 and the second abutting protrusion 211 of the second abutting unit 21 can be set according to actual needs, and is not limited to one first abutting protrusion 111 and one second abutting protrusion 211. It is only necessary that there is at least one first abutting protrusion 111 and one second abutting protrusion 211, and each first abutting protrusion 111 corresponds to each second abutting protrusion 211 and is opposite to each other along the first direction X. For example, in some other embodiments, the first abutment unit 11 has two first abutment protrusions 111, which are arranged along the second direction Y. The second abutment unit 21 also has two second abutment protrusions 211, which are also arranged along the second direction Y. One first abutment protrusion 111 and one second abutment protrusion 211 correspond to each other and are opposite each other along the first direction X, and are spaced apart. Another first abutment protrusion 111 and another second abutment protrusion 211 correspond to each other and are opposite each other along the first direction X, and are spaced apart.

[0065] In some embodiments, the first connecting plate 12 and the second connecting plate 22 are slidably connected along the first direction X.

[0066] In some embodiments, the first abutting unit 11 is provided with a first abutting side 1111 and a first pressing side on one side along the first direction X, with the first pressing side located at the top of the first abutting side 1111. Alternatively, as... Figure 6 As shown, the second abutment unit 21 has a second abutment side 2111 and a second pressing side 2112 on one side along the first direction X, with the second pressing side 2112 located at the top of the second abutment side 2111. Alternatively, the first abutment protrusion 111 has a first abutment side 1111 and a first pressing side on one side along the first direction X, with the first pressing side located at the top of the first abutment side 1111, and the second abutment protrusion 211 has a second abutment side 2111 and a second pressing side 2112 on one side along the first direction X, with the second pressing side 2112 located at the top of the second abutment side 2111.

[0067] The first abutting side 1111 is used to abut against one side of the rod 2000 along the first direction X, the first pressing side is used to abut against the top side of the rod 2000 and press the rod 2000; the second abutting side 2111 is used to abut against the other side of the rod 2000 along the first direction X, and the second pressing side 2112 is used to abut against the top side of the rod 2000 and press the rod 2000.

[0068] In this embodiment, by providing a first pressing side and / or a second pressing side 2112, when the first abutting side 1111 and the second abutting side 2111 abut against the two sides of the rod 2000 along the first direction X, the first pressing side and / or the second pressing side 2112 can abut against and press the rod 2000 on the top side of the rod 2000, so that the rod 2000 can be firmly pressed in the clamping device 100, ensuring the stability of the rod 2000 when it is clamped.

[0069] In some embodiments, the first pressing side is inclined or arcuately arranged relative to the first supporting side 1111. Alternatively, the second pressing side 2112 is inclined or arcuately arranged relative to the second supporting side 2111. Alternatively, the first pressing side is inclined or arcuately arranged relative to the first supporting side 1111, and the second pressing side 2112 is inclined or arcuately arranged relative to the second supporting side 2111. By making the pressing side (first pressing side or second pressing side 2112) inclined or arc-shaped, when the pressing side (first pressing side or second pressing side 2112) abuts against the rod 2000 along the first direction X with the supporting side (first supporting side 1111 or second supporting side 2111), the pressing side (first pressing side or second pressing side 2112) can apply a pressing component force on the rod 2000 from its top side to its bottom side, so that the rod 2000 can be pressed in the clamping device 100 from its top side to its bottom side.

[0070] Specifically, the first abutting side 1111 and the first pressing side are both disposed on one side of the first abutting protrusion 111 along the first direction X; the second abutting side 2111 and the second pressing side 2112 are both disposed on one side of the second abutting protrusion 211 along the first direction X.

[0071] like Figure 2 As shown, in some embodiments, the clamping device 100 further includes a drive mechanism 30, which is connected to the first abutment mechanism 10 or the second abutment mechanism 20. The drive mechanism 30 is used to drive the first abutment mechanism 10 and the second abutment mechanism 20 to move relative to each other along a first direction X.

[0072] Specifically, the drive mechanism 30 is connected to the second abutment mechanism 20, and the drive mechanism 30 is used to drive the second abutment mechanism 20 to move relative to the first abutment mechanism 10 along the first direction X.

[0073] More specifically, the first abutment mechanism 10 also includes a mounting plate 13, which is connected to one of the aforementioned first connecting plates 12. A drive mechanism 30 is mounted on the mounting plate 13, and the output end of the drive mechanism 30 is connected to the second connecting plate 22. The output end of the drive mechanism 30 can drive the second connecting plate 22 to move relative to the first connecting plate 12 along the first direction X. The second connecting plate 22 drives each of the second abutment units 21 on it to move toward or away from each other and the corresponding first abutment units 11 on the first connecting plate 12.

[0074] The drive mechanism 30 can be a first telescopic cylinder, the cylinder body of which is mounted on the mounting plate 13, and the output end of which is connected to the second connecting plate 22.

[0075] In some other embodiments, the drive mechanism 30 may also be connected to the first abutment mechanism 10, and the drive mechanism 30 is used to drive the first abutment mechanism 10 to move relative to the second abutment mechanism 20 in a first direction X.

[0076] In some embodiments, the clamping device 100 further includes a lifting mechanism 40, which is connected to the first abutment mechanism 10 and the second abutment mechanism 20 respectively, and the lifting mechanism 40 is used to drive the first abutment mechanism 10 and the second abutment mechanism 20 to rise and fall.

[0077] In some embodiments, the clamping device 100 further includes a guide mechanism 50, which is connected to the first abutment mechanism 10 and the second abutment mechanism 20 respectively. The guide mechanism 50 is used to guide the first abutment mechanism 10 and the second abutment mechanism 20 to move up and down along a third direction Z, which is perpendicular to the first direction X and the second direction Y respectively.

[0078] Specifically, the guide mechanism 50 includes a fixed base 51, a guide sleeve 52, and a guide shaft 53. The guide sleeve 52 is installed on the fixed base 51 and sleeved on the outside of the guide shaft 53. One end of the guide shaft 53 is connected to the mounting plate 13.

The lifting mechanism 40 is installed on the fixed base 51, and the output end of the lifting mechanism 40 is connected to the fixed plate. The output end of the lifting mechanism 40 can drive the fixed plate to move the first supporting mechanism 10 and the second supporting mechanism 20 up and down along the third direction Z.

[0079] The lifting mechanism 40 can be a second telescopic cylinder. The cylinder body of the second telescopic cylinder is mounted on the fixed base 51, and the output end of the second telescopic cylinder is connected to the mounting plate 13.

[0080] like Figure 1 As shown, this embodiment of the present invention also provides a warp threading machine 1000, which includes a support 300, a heddle roller 200, and a clamping device 100 as described in any of the above embodiments. The heddle roller 200 is rotatably connected to the support 300, and the clamping device 100 is mounted on the support 300.

[0081] Specifically, there are two clamping devices 100, and the two clamping devices 100 and the heddle wheel 200 are spaced apart along the second direction Y. The heddle wheel 200 defines a plurality of grooves 210, and each groove 210 corresponds to a first abutting unit 11 and a second abutting unit 21 in each clamping device 100.

[0082] The rod 2000 is placed between a first abutting unit 11 and a second abutting unit 21 in the clamping device 100, and the end of the rod 2000 is located in the groove 210 of the heddle wheel 200.

[0083] The threading machine 1000 of this utility model embodiment has the beneficial effects of the clamping device 100, which will not be described in detail here.

[0084] For ease of explanation, the clamping device 100 closer to the heddle wheel 200 is referred to as the first clamping device, and the other clamping device 100 farther away from the heddle wheel 200 is referred to as the second clamping device. The working principle of the threading machine 1000 is explained by example below:

[0085] The rod 2000 is placed on the heddle wheel 200, the first clamping device, and the second clamping device, and is clamped by the first clamping device and the second clamping device. After the heddle wire enters the heddle rod 2000 from its end (the end of the heddle rod 2000 is located on the side of the heddle roller 200 away from the first clamping device), the heddle roller 200 rotates one revolution, allowing the heddle wire to move from the side of the heddle roller 200 away from the first clamping device to the other side of the heddle roller 200 closer to the first clamping device. At this time, the heddle wire is between the heddle roller 200 and the first clamping device. When the heddle wire needs to continue moving in the direction from the first clamping device to the second clamping device, the first telescopic cylinder of the first clamping device drives the corresponding first abutment unit 11 and the second abutment unit 21 to move away from each other, so as to release the clamping effect on the heddle rod 2000. Then, the second telescopic cylinder of the first clamping device drives the corresponding first abutment mechanism 10 and the second abutment mechanism 20 to descend, so as to completely disengage from the heddle rod 2000. At this time, the heddle wire can continue to move in the direction from the first clamping device to the second clamping device to the space between the first clamping device and the second clamping device. When the heald wire needs to continue moving in the direction from the first clamping device to the second clamping device, the second telescopic cylinder of the first clamping device drives the corresponding first abutment mechanism 10 and the second abutment mechanism 20 to rise, so that the string rod 2000 is located between the first abutment unit 11 and the second abutment unit 21 of the first clamping device. Then, the first telescopic cylinder of the first clamping device drives the corresponding first abutment unit 11 and the second abutment unit 21 to move toward each other to jointly clamp the string rod 2000. After that, the first telescopic cylinder of the second clamping device drives the corresponding first abutment unit 11 and the second abutment unit 21 to move away from each other to jointly release the clamping effect on the string rod 2000. The second telescopic cylinder of the second clamping device drives the corresponding first abutment mechanism 10 and the second abutment mechanism 20 to descend to completely disengage from the string rod 2000. At this time, the heald wire can continue to move in the direction from the first clamping device to the second clamping device to the side of the second clamping device away from the first clamping device.

[0086] Within the scope of knowledge possessed by those skilled in the art, various modifications can be made without departing from the spirit of this utility model. Furthermore, embodiments of this utility model and features thereof can be combined with each other, unless otherwise specified.
