Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery, in particular to a structure for heat dissipation of a motor of a wrench head. Background Art

[0002] The role of the reed-twisting machine in the weaving process of chemical fiber fabrics is indeed a crucial step. It is mainly responsible for evenly dividing the full-width warp yarn into two or more layers. This process is crucial to improving weaving efficiency and fabric quality. During the operation of the twisting machine, the repeatedly moving movable head on the twisting machine can accurately separate the densely arranged warp yarns one by one through its designed yarn dividing needles or other similar devices, ensuring that each warp yarn can be independently and parallelly guided to the next step of the weaving process, thereby realizing the precise separation and guidance of the warp yarns.

[0003] The head of the reed-twister is generally equipped with a shuttle motor with sensitive transmission and high continuous motion accuracy. The shuttle motor is the core component that directly affects the quality of the yarn-dyed weaving shaft. However, during the operation of the reed-twister, the heat generated by the various components of the machine head during continuous work and the temperature generated by the motor during operation will have a direct impact on the service life of the motor itself, resulting in a very high motor damage rate.

[0004] Therefore, the present application specifically proposes a structure for heat dissipation of the motor of the stranding machine head to solve the above technical problems. Utility Model Content

[0014] Furthermore, two ends of the central shaft are connected and pass through two groups of ball bearings, one group of connecting round blocks is arranged on the mounting bracket, and the other group of connecting round blocks rotates in the movable cavity.

[0015] Furthermore, a plurality of groups of movable steel balls are distributed in a ring shape on one side of the connecting circular block close to the central shaft rod, the movable steel balls are all limitedly embedded in the connecting circular block, and the movable steel balls are all in contact with and connected to the ball bearing.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0030] In the embodiment, see Figures 1 to 5 .

[0031] like Figure 1 As shown, the utility model provides a structure for heat dissipation of the motor of the stranding machine head, which is configured as a heat dissipation component 5, and the heat dissipation component 5 is arranged below the shuttle selection motor 2 and is arranged on the stranding machine head frame 1 through the mounting bracket 4.

[0032] For the stranding machine head frame 1, the stranding machine head frame 1 is arranged on the stranding machine frame 3. Meanwhile, during the operation of the stranding machine, the stranding machine head frame 1 moves back and forth repeatedly at high speed along a straight path on the stranding machine frame 3.

[0033] At this time, the fan is directly arranged below the shuttle selection motor 2. Such a layout can ensure that the airflow generated by the fan directly acts on the surface of the shuttle selection motor 2, effectively taking away the heat generated during the operation of the shuttle selection motor 2, improving the heat dissipation efficiency, and thus extending the service life of the shuttle selection motor 2, ensuring the twisting quality of the weaving shaft.

[0034] Specifically, Figure 2 As shown, the heat dissipation component 5 includes:

[0035] The rotating shaft block 54 is arranged on the mounting bracket 4;

[0036] The rotating sleeve 52 is limitedly rotated on the rotating shaft block 54;

[0037] The cooling fan 51 is composed of a fan shaft 512 and a plurality of fan blades 511 located on the fan shaft 512. The fan shaft 512 is integrally arranged at the top of the rotating sleeve 52.

[0038] The linkage member is used to drive the rotating sleeve 52 to rotate on the rotating shaft block 54 when the rotating sleeve 52 approaches and moves away from the frame 3 of the one side of the winch.

[0039] In a specific implementation, the rotating sleeve 52 in the heat dissipation assembly 5 drives the heat dissipation fan 51 to rotate within the upper limit of the rotating shaft block 54, and the rotating sleeve 52 is driven to rotate on the rotating shaft block 54 through a linkage control during the process of the rotating sleeve 52 approaching and moving away from the twisting machine frame 3. Therefore, the rotating sleeve 52 can be automatically driven to drive the heat dissipation fan 51 to rotate during the operation of the twisting machine to control the movement of the machine head, thereby completing the heat dissipation operation of the shuttle selection motor 2, without the need for an additional power source to separately control the rotation of the heat dissipation fan 51.

[0040] In a further implementation process, when the rotating sleeve 52 approaches and moves away from one side of the winch frame 3, the linkage will control the rotating sleeve 52 to drive the cooling fan 51 to rotate in different directions, completing the fan's blowing operation on the air suction of the shuttle selection motor 2.

[0041] It should be noted that, regardless of the suction or blowing operation on the shuttle selection motor 2 , air flow exchange of part of the shuttle selection motor 2 can be performed, that is, the heat dissipation operation of the shuttle selection motor 2 can be completed.

[0042] In addition, the cooling fan 51 can generally be directly used as the cooling fan 51 of the computer host in actual product use, and the actual effect after installing the cooling fan 51 can greatly reduce the working temperature of the shuttle selection motor 2, extend the service life of the shuttle selection motor 2, reduce the consumption of machine materials, ensure the quality of the weaving shaft, and provide strong support for the production of subsequent processes.

[0043] In a further specific embodiment, Figure 3 and Figure 4 As shown, a movable cavity 522 is provided inside the rotating sleeve 52 , and the bottom opening of the rotating sleeve 52 is used to communicate with the movable cavity 522 . Two sets of parallel distributed ball bearings 523 are provided inside the movable cavity 522 for connecting the rotating shaft block 54 .

[0044] Therefore, the rotating sleeve 52 can rotate smoothly on the rotating shaft block 54, and the rolling friction is used instead of the sliding friction, which greatly reduces the friction and wear, and improves the smoothness and efficiency of the rotation. The parallel distribution of the two sets of rotating shaft blocks 54 also ensures that the rotating sleeve 52 is subjected to balanced forces in different directions, enhances the stability of the rotating sleeve 52 during rotation, and also enables the rotating sleeve 52 to move more flexibly along the rotating shaft block 54, thereby ensuring good power transmission and long-term operating reliability.

[0045] The rotating shaft block 54 is composed of a central shaft 541 and connecting round blocks 542 located on both sides of the central shaft 541. At the same time, in the specific connection structure of the device, the two ends of the central shaft 541 are connected and pass through two groups of ball bearings 523. One group of connecting round blocks 542 is set on the mounting bracket 4, and the other group of connecting round blocks 542 rotates in the movable cavity 522, which can limit the rotating sleeve 52 to rotate on the rotating shaft block 54.

[0046] Furthermore, a plurality of groups of movable steel balls 543 are distributed in a ring on one side of the connecting round block 542 close to the central shaft 541. The movable steel balls 543 are all limitedly embedded in the connecting round block 542, and the movable steel balls 543 are all in contact with the ball bearing 523. This can further disperse the load, reduce the pressure at each contact point, and enhance the rotation efficiency of the rotating sleeve 52 on the rotating shaft block 54, while also improving the flexibility and stability of the rotation of the rotating sleeve 52 and reducing unnecessary wear.

[0047] In a further specific embodiment, Figure 4 and Figure 5 As shown, an annular groove 521 is provided on the outer side of the rotating sleeve 52, and the linkage member includes a winding rope 53 wound in the annular groove 521 and a coil spring 55 arranged in the middle of the central shaft 541, wherein: one end of the winding rope 53 is arranged in the annular groove 521, and the other end of the winding rope 53 is arranged on the frame 3 of the twisting machine, and the coil spring 55 is connected to the inner wall of the movable cavity 522.

[0048] Therefore, when the rotating sleeve 52 is away from one side of the winch frame 3, the rotating sleeve 52 can be driven to rotate on the rotating shaft block 54 by winding the pull rope 53. When the rotating sleeve 52 is close to one side of the winch frame 3, the rotating sleeve 52 can be driven to rotate in the opposite direction on the rotating shaft block 54 by the winding spring 55. The rotation of the rotating sleeve 52 on the rotating shaft block 54 can complete the blowing and suction operations of the shuttle selection motor 2, thereby completing the hot air exchange operation of the shuttle selection motor 2 and performing the heat dissipation treatment of the shuttle selection motor 2. There is no need for an additional power source to separately control the rotation of the cooling fan 51, and the continuous rotation of the cooling fan 51 can be ensured during the operation of the winch, thereby further ensuring the heat dissipation efficiency and heat dissipation effect of the shuttle selection motor 2, which is convenient for practical use.

[0049] In addition, it should be noted that when the rotating sleeve 52 is farthest away from the frame 3 of the twisting machine on one side, the winding rope 53 still has more than half a circle of winding remaining in the annular groove 521, which can ensure that when the rotating sleeve 52 approaches the frame 3 of the twisting machine on one side, the winding spring 55 controls the rotating sleeve 52 to rotate in the opposite direction on the rotating shaft block 54, so as to rewind the winding rope 53, thereby ensuring the reasonable and continuous operation of the structure during actual use.

[0050] 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 in the protection scope of the present invention.

[0051] In addition, it should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0052] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

In addition, in the embodiments of the utility model, "multiple" refers to more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.
