Description

Technical Field

[0001] This invention belongs to the field of winding machine technology, specifically a shaftless winding machine. Background Technology

[0002] Existing products often use horizontal winding machines for winding. Horizontal bearing winding machines wind the inner tube by passing it through a horizontal shaft, and then use a multi-axis robot to achieve fiber winding and winding control. This relies on a control unit with more than four axes, which has the following problems.

[0003] 1. Due to the limitations of the length of the horizontal shaft winding machine and the overall size of the winding machine, it is impossible to manufacture larger winding products;

[0004] 2. Because the horizontal shaft winding machine winds the product by rotating a horizontal motor, it requires a very large motor torque and has higher electrical requirements, thus making it impossible to manufacture larger products.

[0005] 3. Horizontal shaft winding machines often rely on multi-axis control and precision management, thus incurring higher costs;

[0006] 4. When horizontal shaft winding machines perform large-size winding, they often rely on larger motors and higher speeds, which can create certain dangers.

[0007] 5. Horizontal shaft winding machines operate at non-uniform speeds, resulting in varying speeds and tensions during the production process. Consequently, achieving stable product quality is often very difficult. Summary of the Invention

[0008] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

The position of the protruding strip and the position of the limiting groove are correspondingly set. By using the protruding strip and the limiting groove, the rotating shaft can be linked to the linkage column to rotate when rotating.

[0014] As a preferred technical solution for shaftless winding machines, the upper bracket has an installation cavity on the side near the through hole, and a gear is rotatably connected in the installation cavity. The outer side of the linkage column is provided with an annular tooth, and the gear meshes with the linkage column for transmission.

[0017] 1. The central rotation of the traditional horizontal axis motor is changed to side rotation, thus reducing the need for a speed reducer and torque.

[0018] 2. By utilizing the winding component, the winding size can be increased, and the shaftless winding machine can achieve ultra-large size winding;

[0019] 3. The use of a winding drum that synchronizes telescopic extension and rotation results in more stable winding, and the shaftless winding machine can achieve uniform winding speed;

[0033] Example 1

[0034] Reference Figure 1 , 2 5. This is the first embodiment of the present invention, which provides a shaftless winding machine, a base 100 and a winding member 300. The winding member 300 is spherical. A control seat 200 is provided on the top of the base 100. A transmission wheel 201 is rotatably connected to the top of the control seat 200. The winding member 300 is placed on top of multiple transmission wheels 201, so that the winding member 300 is controlled to rotate by the transmission wheels 201. A universal motor 202 is installed in the control seat 200. The top of the universal motor 202 is connected to the bottom of the transmission wheel 201, so that the universal motor 202 can drive the transmission wheel 201 to rotate. When the transmission wheel 201 rotates, it can drive the winding member 300 to rotate in conjunction, thereby winding the thread.

[0035] This implementation enables the following: the thread is wound around the inner liner of the winding member 300. At this time, the transmission wheel 201 is driven to rotate by the control system, and the winding member 300 rolls. The universal motor 202 is used to control the transmission wheel 201 to rotate by a pre-set control algorithm. At this time, the winding member 300 can better wind the thread at a certain angle.

[0036] Example 2

[0037] Reference Figures 1 to 4 As shown, this is the second embodiment of the present invention. This embodiment differs from the previous embodiment in that: a base plate 400 is provided at one end of the base 100, and a support frame 500 and a lower support 600 are provided on the base plate 400. A guide frame 501 is rotatably connected between the two support frames 500, wherein the guide frame 501 is used to pull the wire to wind around the winding member 300; an upper support 601 is provided above the lower support 600, and the lower support 600 and the upper support 601 are distributed in parallel. A rotatable rotating shaft 602 is provided on the top surface of the lower support 600, wherein the rotating shaft 602 is controlled to rotate by a drive assembly.

[0038] Furthermore, a through hole 604 is provided on the surface of the upper bracket 601, and a linkage column 605 is telescopically connected in the through hole 604. A docking groove 606 is provided at the bottom end of the linkage column 605, and the top end of the rotating shaft 602 is located in the docking groove 606. A protrusion 603 is provided on the outer side of the rotating shaft 602, and a limiting groove 607 is provided on the inner edge of the docking groove 606. The position of the protrusion 603 corresponds to the position of the limiting groove 607. Using the protrusion 603 and the limiting groove 607, the rotating shaft 602 rotates... The linkage column 605 can be rotated. The upper bracket 601 has a mounting cavity 608 on the side near the through hole 604. A gear 609 is rotatably connected in the mounting cavity 608. The outer side of the linkage column 605 is provided with ring teeth. The gear 609 meshes with the linkage column 605 for transmission. The meshing transmission structure causes the linkage column 605 to move up and down. A wire feeding frame 610 is installed at the top of the linkage column 605. A winding cylinder 611 is provided on the outer side of the wire feeding frame 610. The winding cylinder 611 is used for feeding wire.

[0039] This implementation achieves the following: During the unwinding process, the drive mechanism in the lower support 600 continuously controls the rotating shaft 602 to rotate. At this time, the winding drum 611 can rotate during unwinding, thus avoiding the jamming phenomenon that is easily caused by the conventional thread pulling the winding drum 611. Meanwhile, the gear 609 rotates reciprocally, and the two adjacent linkage columns 605 are placed in different positions in advance, so as to avoid mutual interference when multiple winding drums 611 are unwinding and winding at the same time. By using the meshing transmission structure, the winding drum 611 can also reciprocate up and down while rotating, so as to meet the different needs of the irregularly wound thread on the surface of the winding drum 611 during unwinding, making the winding component 300 smoother when winding the thread.

[0040] In actual use, when the line is wound around the winding member 300, the diameter of the winding member 300 is 10 meters, while the diameter of the winding line is 0.1 millimeters. Since the balloon has the characteristic of expansion, the diameter is expanded in the area without winding, thus compensating for the diameter change caused by the winding line.

[0041] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
