Description

Technical Field

[0001] This utility model relates to the field of capillary winding equipment technology, specifically an automatic fixed-length winding machine. Background Technology

[0002] In the field of capillary processing, winding large-diameter copper capillaries (such as large coils with an initial diameter of 700mm) into small-diameter coils (such as small coils with a diameter of 130mm) is a common production requirement. However, traditional winding equipment lacks effective control over the capillary path during the winding process, causing the capillaries to easily become knotted and piled up due to lateral deviation. This not only seriously affects the regularity of the coils and product quality but also requires manual intervention to tidy them up, significantly increasing production time and costs.

[0003] Chinese Patent Publication No. CN222475791U discloses a capillary winding device and a winding tool for a tube, comprising: a first groove with a first positioning sleeve that can slide along the first groove; and a second groove with a second positioning sleeve that can slide along the second groove, wherein the extension directions of the first and second grooves do not coincide. This application utilizes the sliding first and second positioning sleeves to achieve capillary winding of different structures, unifying the winding tooling, avoiding frequent tooling changes, and improving winding efficiency. While the above-mentioned device solves the tooling switching problem by adjusting the winding structure through the sliding positioning sleeve, it lacks a device to actively limit the capillary winding path (such as the capillary limiting bracket and horizontal limiting rod directly above the winding roller in this application), thus failing to effectively constrain the lateral displacement of the capillary, and knotting and accumulation may still occur during the winding process. Summary of the Invention

[0004] The present invention aims to solve the above-mentioned prior art and improve winding efficiency.

[0005] The technical solutions adopted in this utility model are as follows:

[0006] An automatic fixed-length tube winding machine includes an overall support, a winding component, a capillary pulley platform, and a capillary limiting bracket; the winding component, the capillary pulley platform, and the capillary limiting bracket are all assembled on the overall support.

[0007] The winding component is fixed to the overall bracket through mounting holes;

[0008] The capillary pulley platform is connected to the overall bracket through the mounting hole at the bottom; the capillary limiting bracket is installed directly above the winding roller of the winding component.

[0009] By adopting the above technical solution, the assembly relationship between the overall support and the winding component, capillary pulley platform, and capillary limiting support is achieved by integrating each core functional component onto the same overall support. This realizes the compactness and modularity of the equipment structure, avoids the problems of component loosening or positional displacement caused by traditional decentralized design, and improves the collaborative work efficiency between components by unifying the assembly benchmark.

[0010] Furthermore, the overall bracket adopts an integrated design and is equipped with four casters at the bottom; the overall bracket has at least eight mounting holes.

[0011] By adopting the above technical solution, the overall support adopts an integrated design and is equipped with bottom casters. The integrated molding enhances the structural strength and stability of the support, while the casters improve the overall mobility of the equipment. The uniform layout of at least 8 mounting holes on the support provides standardized installation interfaces for functional modules such as winding components and pulley platforms, which significantly reduces assembly difficulty and shortens equipment debugging time.

[0012] Furthermore, the winding component includes a motor, a winding roller, and a connector; the motor and the winding roller are securely connected by the connector, and both ends of the connector are fixed to the motor output shaft and the winding roller shaft, respectively.

[0013] By adopting the above technical solution, the assembly method of the motor and the winding drum in the winding component being firmly connected by connectors ensures the coaxiality and transmission stability of the motor output shaft and the winding drum shaft, avoiding power transmission loss or drum rotation deviation caused by loose connection, and providing reliable power support for capillary winding.

[0014] Furthermore, the capillary pulley platform includes a pulley bracket, a pulley shaft, and a pulley; the pulley bracket has four shaft holes, the pulley shaft passes through the shaft holes and is rotatably connected to the pulley; the bottom of the pulley bracket is bolted to the corresponding holes of the overall bracket through four mounting holes.

[0015] By adopting the above technical solution, the assembly relationship in which the pulley shaft of the capillary pulley platform passes through the shaft hole of the pulley bracket and is rotatably connected to the pulley not only ensures the ability of the pulley to rotate flexibly around the shaft (reducing the frictional resistance during capillary transport), but also achieves the stable fixation of the pulley platform through the bolt connection between the four mounting holes at the bottom of the pulley bracket and the overall bracket, thus avoiding deviation of the capillary transport path caused by the positional offset of the pulley.

[0016] Furthermore, the rib plate of the pulley bracket is provided with four meter counter mounting holes, through which the meter counter is fixed to the pulley bracket; the meter counter is electrically connected to the motor of the winding component.

[0017] By adopting the above technical solution, the assembly design of the meter counter mounting hole on the pulley bracket rib plate being electrically connected to the motor ensures the accuracy of length measurement by directly fixing the meter counter to the pulley bracket (closely related to the capillary conveying path); at the same time, the electrical linkage with the motor allows the motor to be automatically stopped when the winding length reaches the set value, realizing the automation of fixed-length winding and avoiding delays and errors caused by manual intervention.

[0018] Furthermore, the capillary limiting bracket includes a limiting rod and a bracket body; one end of the bracket body is fixed to the overall bracket, and the other end extends to directly above the winding roller of the winding component, and the limiting rod is horizontally fixed to the extended end of the bracket body.

[0019] By adopting the above technical solution, the capillary limiting bracket has an assembly structure in which the bracket body extends to the top of the winding drum and horizontally fixes the limiting rod. Through the lateral constraint of the limiting rod on the capillary, the deviation of the capillary during the winding process is effectively limited, so that the capillary can be evenly arranged along the axis of the drum, which significantly improves the regularity and consistency of the winding and reduces the occurrence of problems such as knotting and accumulation.

[0020] This utility model has the following beneficial effects:

[0021] 1. The overall support frame of this utility model adopts an integrated design and is equipped with bottom casters. The integrated structure enhances the overall structural strength and stability of the equipment, while the casters enable flexible movement of the equipment, significantly improving its adaptability and ease of operation in production scenarios.

[0022] 2. This utility model ensures the coaxiality and stability of power transmission by stably connecting the motor and the winding roller in the winding component through a connector, avoiding the problems of offset or loosening during the transmission process, providing continuous and reliable power support for capillary winding, and effectively improving winding efficiency.

[0023] 3. This utility model uses the pulley shaft and pulley rotation connection structure of the capillary pulley platform to reduce frictional resistance during capillary transport and reduce losses during the transport process; at the same time, the electrical linkage design between the meter counter on the pulley bracket and the motor realizes automatic and precise control of the winding length, and fixed-length winding can be completed without manual measurement, which greatly reduces operation error.

[0024] 4. This utility model uses a capillary limiting bracket with its limiting rod horizontally fixed above the winding roller. By actively constraining the lateral displacement of the capillary, it effectively avoids the knotting and accumulation of the capillary during the winding process, significantly improving the regularity of the coil and the consistency of the product, and reducing the cost of manual intervention.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and specific preferred embodiments.

[0034] In the description of this utility model, it should be understood that the terms "left side," "right side," "upper part," "lower part," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. "First," "second," etc., do not indicate the importance of the components, and therefore should not be construed as a limitation of this utility model. The specific dimensions used in this embodiment are only for illustrating the technical solution and do not limit the protection scope of this utility model.

[0035] Reference Figure 1 , Figure 2 and Figure 3As can be seen, this utility model discloses an automatic fixed-length tube winding machine. The various components of this device are tightly assembled through standardized interfaces and structural design: the overall support 10 serves as the basic carrier, adopting an integrated design and equipped with four casters 11 at the bottom. Its surface has at least eight mounting holes, providing a unified installation reference for other core components; the winding component 20 is directly fixed to the overall support 10 through the mounting holes, and its internal motor 21 and winding roller 22 are securely connected through a connector 23. The two ends of the connector 23 are respectively fixed to the output shaft of the motor 21 and the rotating shaft of the winding roller 22, forming a stable power transmission structure; the capillary pulley platform 30... The bottom of the pulley bracket 31 is bolted to the corresponding holes of the overall bracket 10 through four mounting holes. The pulley shaft 32 passes through the four shaft holes of the pulley bracket 31 and is rotatably connected to the pulley 33. At the same time, the meter counter is fixed on the rib plate 311 of the pulley bracket 31 through four meter counter mounting holes 3111. The meter counter is electrically connected to the motor 21 of the winding component 20. One end of the bracket body 42 of the capillary limiting bracket 40 is fixed to the overall bracket 10, and the other end extends to the top of the winding roller 22 of the winding component 20. The limiting rod 41 is horizontally fixed to the extension end of the bracket body 42, forming a lateral constraint structure for the capillary winding path.

[0036] In one embodiment, refer to Figure 1 and Figure 2 As can be seen, firstly, the capillary tube is conveyed from its initial position to the capillary pulley platform 30. The pulley shaft 32 is guided by the pulley 33 to pass through the shaft hole of the pulley bracket 31 and rotates with the pulley 33, reducing conveying friction as it enters the winding area. Subsequently, the motor 21 of the winding component 20 starts, driving the winding drum 22 to rotate via the connector 23, providing winding power. During the winding process, the limiting rod 41 of the capillary limiting bracket 40 is horizontally fixed directly above the winding drum 22, applying lateral constraint to the capillary tube to prevent it from shifting or piling up, ensuring uniform arrangement along the drum axis. Simultaneously, the meter counter on the rib plate 311 of the pulley bracket 31 measures the capillary tube conveying length in real time. When the set value is reached, the meter counter sends a signal through its electrical connection with the motor 21, controlling the motor 21 to stop, completing the automatic fixed-length winding.

[0037] In one embodiment, refer to Figure 3It is known that one end of the support body 42 is fixed to the overall support 10, and the other end extends to the top of the winding roller 22 of the winding component 20. The limiting rod 41 is horizontally fixed to the extension end of the support body 42, forming a lateral coverage of the area above the winding roller 22. When the capillary 50 is pulled by the winding roller 22 for winding, the path of the capillary from the initial position to the winding roller 22 will pass under or to the side of the limiting rod 41. The limiting rod 41 applies a lateral limiting effect to the capillary 50 through the horizontally set structure, limiting its excessive displacement to both sides of the roller axis during the winding process. Through continuous lateral constraint, the capillary 50 is guided to be evenly arranged along the axis of the winding roller 22, avoiding knotting, accumulation or disordered arrangement caused by displacement, and finally achieving regular winding of the capillary 50 on the roller.

[0038] Working Principle: First, the overall support frame 10 serves as the basic carrier, providing stable support through its integrated structure, while the bottom casters 11 enable flexible movement of the equipment. The motor 21 of the winding component 20 is securely connected to the winding roller 22 via the connector 23. After the motor starts, it drives the roller to rotate, providing the core power for capillary winding. The capillary 50 enters the capillary pulley platform 30 from its initial position, and is guided by the pulley 33 to the conveying pulley shaft 32, which is connected to the pulley for rotation, reducing conveying friction resistance and simultaneously triggering the length measurement function of the meter counter on the pulley support 31. The meter counter monitors the capillary conveying length in real time and feeds back the length signal to the motor control system through its electrical connection with the motor 21. When the capillary 50 is pulled into the winding area by the winding roller 22, the limiting rod 41 of the capillary limiting support 40 is horizontally fixed directly above the roller, applying lateral constraint to the capillary 50 and limiting its deviation to both sides of the roller axis, ensuring that the capillary is evenly distributed along the roller surface and avoiding knotting or accumulation. When the meter counter detects that the capillary tube 50 has reached the preset length, it immediately sends a stop signal to the motor 21. The motor stops rotating, and the winding drum 22 stops synchronously, thus completing the automatic length setting and regular winding of the capillary tube 50.

Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and all such equivalent transformations fall within the protection scope of the present invention.
