Description

An automatic winding device with an anti-loosening clamping mechanism Technical Field

[0001] This utility model relates to the field of winding equipment technology, specifically to an automatic winding device with an anti-loosening clamping mechanism. Background Technology

[0002] In modern industrial production and daily life, automatic winding devices are widely used in many fields such as wire and cable manufacturing, electronic component production, textiles, and medical equipment manufacturing. They can efficiently and accurately wind wires into coils that meet the requirements, greatly improving production efficiency and product quality.

[0003] A search revealed that patent publication number CN215625858U discloses a winding device for preventing loosening of power cables. The device includes a winding frame with a groove at its top. A winding roller is movably fitted into the bottom of the groove's inner cavity. A positioning plate located inside the winding frame is fixedly fitted onto the outer surface of the winding roller. The right end of the positioning plate is movably connected to the right side of the winding frame's inner cavity. This invention, by incorporating a connecting rod, a rotating block, and a lead screw, utilizes the fixed plate. Rotating the rotating block moves the connecting plate via the lead screw, which in turn moves the winding roller and positioning plate as a whole. The anti-loosening block ensures that the connecting plate does not detach from the lead screw during movement, guaranteeing stability. This allows the winding roller and positioning plate to move as a whole, changing the distance between the positioning plate and the base, thereby enabling the winding of cables of different lengths.

[0004] In existing winding devices, as the amount of wire wound on the winding roller increases and the winding diameter gradually increases, the force distribution on the wire becomes uneven during winding. When the wire stops winding and is cut, it is prone to loosening and detachment. To solve the problem of wire detachment, some winding devices use simple mechanical clamping structures, such as manually adjusting the clamping blocks to clamp the wire. This method requires manual clamping of the wire on the winding roller after each winding, which affects work efficiency. Therefore, an automatic winding device with an anti-loosening clamping mechanism is designed. Summary of the Invention

[0005] In view of the defects or deficiencies of existing winding devices, the purpose of this utility model is to provide an automatic winding device with an anti-loosening clamping mechanism, which can automatically complete the winding and stopping operation without the need for constant manual monitoring and intervention, realize the control of the winding amount, and effectively prevent the wire from coming loose after winding.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0007] This utility model provides an automatic winding device with an anti-loosening clamping mechanism, including a mounting frame. The top of the mounting frame is provided with a winding mechanism for winding wire and an elastic clamping mechanism for clamping the wire wound on the winding roller of the winding mechanism in the Y-axis direction, and the elastic clamping mechanism is located directly below the winding roller.

[0008] The elastic clamping mechanism is provided with an elastic clamping component for applying a certain clamping force to the wire wound by the winding roller and automatically closing the winding mechanism. The elastic clamping mechanism is provided with an electric telescopic rod for driving the elastic clamping component to move in the Y-axis direction and a guide component for limiting and guiding the movement of the elastic clamping component in the Y-axis direction.

[0009] Preferably, the elastic clamping assembly is provided with a clamping roller, which is located inside the U-shaped mounting plate, and the connecting shafts on both ends of the clamping roller are respectively installed in the bearings on the outer walls of both sides of the U-shaped mounting plate. The bottom end of the U-shaped mounting plate is equipped with limiting posts distributed in a rectangular array.

[0010] Preferably, the bottom end of the limiting post passes through the through hole on the surface of the connecting plate and is connected to the first limiting plate. The limiting post and the first limiting plate are connected by a threaded fit, and the outer wall of the limiting post and the through hole on the connecting plate are in clearance fit. A U-shaped lifting plate is installed at the bottom end of the connecting plate, and a touch switch is installed at the bottom inner side of the U-shaped lifting plate.

[0011] A first spring is sleeved on the outer side of the outer wall of the limiting post, and the first spring is located between the connecting plate and the U-shaped mounting plate.

[0012] Preferably, the electric telescopic rod is installed at the top of the mounting frame, and the telescopic end of the electric telescopic rod is installed at the bottom of the U-shaped lifting plate.

[0013] Preferably, the guide assembly is provided with a fixing plate, and the fixing plate is fixedly connected to the mounting bracket by fastening bolts. A guide post is installed at the center of the upper surface of the fixing plate, and a second limiting plate is installed at the top of the guide post. The second limiting plate and the guide post are connected by threaded engagement.

[0014] Preferably, an annular movable plate is provided on the circumferential outer wall of the guide post, and the circumferential inner wall of the annular movable plate and the circumferential inner wall of the guide post are in clearance fit. A second spring is sleeved on the outer side of the outer wall of the guide post, and the second spring is located between the annular movable plate and the fixed plate. A connecting frame is provided on the upper surface of the annular movable plate, and the top end of the connecting frame is fixedly connected to the connecting plate by fastening bolts.

[0015] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:

[0016] 1. In this utility model, through a series of coordinated structural arrangements, when the equipment winds the wire, the operator first activates the electric telescopic rod, which then moves the elastic clamping assembly to a certain horizontal height before activating the winding mechanism. The winding roller on the winding mechanism winds the wire. When the winding roller winds a certain amount of wire, the wire exerts a certain force on the clamping roller during the winding process. After being subjected to a certain force, the clamping roller compresses the spring. The spring's compression and rebound force clamps the wire. When the clamping roller is subjected to a certain squeezing force and the spring is compressed to a certain extent, the bottom end of the limit post touches the touch switch. The touch switch closes the winding mechanism and stops winding the wire. Thus, this utility model can not only automatically complete the winding and stopping operations without constant manual monitoring and intervention, but also effectively prevent the wire from coming loose after winding and cutting.

[0017] 2. In this utility model, through a series of coordinated structural arrangements, the operator activates the electric telescopic rod, which drives the elastic clamping component to move linearly in the Y-axis direction. This allows adjustment of the horizontal height of the elastic clamping component. The operator can adjust the amount of wire wound by the winding roller by adjusting the horizontal height of the elastic clamping component. Thus, this equipment achieves the function of automatically controlling the amount of wire wound, avoiding the inaccuracies and high costs of relying on manual estimation or complex sensor systems to control the amount of wire wound in traditional winding methods.

Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0033] As shown in Figures 1-5, an automatic winding device with an anti-loosening clamping mechanism includes a mounting frame 100. The top of the mounting frame 100 is provided with a winding mechanism 200 for winding wire and an elastic clamping mechanism 300 for clamping the wire wound on the winding roller of the winding mechanism 200 in the Y-axis direction. The elastic clamping mechanism 300 is located directly below the winding roller.

[0034] The elastic clamping mechanism 300 is provided with an elastic clamping component 310 for applying a certain clamping force to the wire wound by the winding roller and automatically closing the winding mechanism 200. The elastic clamping mechanism 300 is provided with an electric telescopic rod 330 for driving the elastic clamping component 310 to move in the Y-axis direction and a guide component 320 for limiting and guiding the elastic clamping component 310 when it moves in the Y-axis direction.

[0035] The elastic clamping assembly 310 is provided with a clamping roller 311, which is located inside the U-shaped mounting plate 312. The connecting shafts on both ends of the clamping roller 311 are respectively installed in the bearings on the outer walls of both sides of the U-shaped mounting plate 312. The bottom end of the U-shaped mounting plate 312 is equipped with limiting posts 313 arranged in a rectangular array.

[0036] The bottom end of the limiting post 313 passes through the through hole on the surface of the connecting plate 317 and is connected to the first limiting plate 318. The limiting post 313 and the first limiting plate 318 are connected by a threaded engagement, and the outer wall of the limiting post 313 and the through hole on the connecting plate 317 are in clearance fit. Because the limiting post 313 and the first limiting plate 318 are connected by a threaded engagement, the first spring 314 can be disassembled and replaced by the operator. Because the outer wall of the limiting post 313 and the through hole on the connecting plate 317 are in clearance fit, the clamping roller 311 is limited and guided in the direction of movement of the clamping roller 311 after being squeezed to a certain extent. A U-shaped lifting plate 315 is installed at the bottom end of the connecting plate 317, and a touch switch 316 is installed at the bottom inner side of the U-shaped lifting plate 315.

[0037] A first spring 314 is sleeved on the outer side of the outer wall of the limiting post 313, and the first spring 314 is located between the connecting plate 317 and the U-shaped mounting plate 312.

[0038] The electric telescopic rod 330 is installed at the top of the mounting bracket 100, and the telescopic end of the electric telescopic rod 330 is installed at the bottom of the U-shaped lifting plate 315.

[0039] A fixing plate 326 is provided on the guide assembly 320, and the fixing plate 326 is fixedly connected to the mounting bracket 100 by fastening bolts. A guide post 324 is installed at the center of the upper surface of the fixing plate 326. A second limiting plate 322 is installed at the top of the guide post 324, and the second limiting plate 322 and the guide post 324 are connected by a threaded engagement. Because the second limiting plate 322 and the guide post 324 are connected by a threaded engagement, the operator can disassemble and replace the second spring 325.

[0040] An annular movable plate 323 is provided on the outer circumferential wall of the guide post 324, and the inner circumferential wall of the annular movable plate 323 and the inner circumferential wall of the guide post 324 are in clearance fit. Because the inner circumferential wall of the annular movable plate 323 and the inner circumferential wall of the guide post 324 are in clearance fit, the movement of the annular movable plate 323 on the guide post 324 can be limited and guided, thereby limiting and guiding the movement of the elastic clamping assembly 310 in the Y-axis direction, enhancing the stability of the elastic clamping assembly 310 during movement. A second spring 325 is sleeved on the outer side of the outer wall of the guide post 324, and the second spring 325 is located between the annular movable plate 323 and the fixed plate 326. A connecting frame 321 is provided on the upper surface of the annular movable plate 323, and the top end of the connecting frame 321 is fixedly connected to the connecting plate 317 by fastening bolts.

[0041] Working Principle: When in use, connect the external power supply. When the equipment winds the wire, the operator first activates the electric telescopic rod 330, causing it to move the elastic clamping assembly 310 to a certain horizontal height, then activates the winding mechanism 200. The winding rollers on the winding mechanism 200 wind the wire. When the winding rollers wind a certain amount of wire, the wire exerts a certain force on the clamping rollers 311 during the winding process. This force compresses the spring, and the spring's rebound clamps the wire. When the clamping rollers 311 are subjected to a certain squeezing force, and the spring is compressed to a certain extent, the bottom end of the limit post 313 will touch the touch switch 316, turning off the circuit. The closed winding mechanism stops winding the wire, thus this invention can not only automatically complete the winding and stopping operations without constant manual monitoring and intervention, but also effectively avoid the loosening of the wire after winding and cutting. The operator starts the electric telescopic rod 330, which drives the elastic clamping component 310 to move linearly in the Y-axis direction, thereby adjusting the horizontal height of the elastic clamping component 310. The operator can adjust the amount of wire wound by the winding roller by adjusting the horizontal height of the elastic clamping component 310. Thus, this equipment realizes the function of automatically controlling the winding amount, avoiding the inaccuracy and high cost of relying on manual estimation or complex sensor systems to control the winding amount in traditional winding methods.

[0042] The above are merely preferred embodiments of this utility model and are not intended to limit the invention. For those skilled in the art, various modifications and variations can be made to this invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the scope of protection of this invention.
