Description

A tension adjustment mechanism for an automatic winding machine

Technical Field

The utility model relates to the technical field of winding machines, in particular to a tension regulating mechanism of an automatic winding machine.

Background Art

A winding machine is a device that winds linear objects onto a specific workpiece. It is usually used for copper wire winding. Most electrical products need to be wound with enameled copper wire to form an inductor coil. A winding machine can be used to complete this or multiple processes.

The inductor coil can be designed into different shapes according to its function. When the shape of the reel is non-circular, the copper wire is easily wound around the outside of the reel when the reel rotates at a constant speed, which may lead to different tensions. Traditional winding machines lack a structure to adjust the tension, resulting in the copper wire being unable to maintain the same tension when wound around the outside of the coil, which may easily cause the copper wire on the inductor coil to become loose or break due to tension.

DETAILED DESCRIPTION

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. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The utility model provides a tension adjustment mechanism of an automatic winding machine as shown in Figures 1 to 4, including a fixed frame 1, a driving motor 2 is installed on the back of the fixed frame 1, the output shaft of the driving motor 2 passes through the fixed frame 1 and is rotatably connected to the winding shaft 3 through a bearing, a winding roller 4 is clamped on the outer side of the winding shaft 3, a fixed frame 5 is fixed on the inner side of the fixed frame 1, two groups of guide rollers 6 are installed in the inner cavity of the fixed frame 5 through bearings, a slide groove 7 is opened in the inner cavity of the fixed frame 5, a slider 8 is slidably connected to the inner cavity of the slide groove 7, a pressure roller 9 is rotatably connected to the opposite side of the slider 8 through a bearing, and the pressure roller 9 is fitted with the opposite side of the guide roller 6, a support spring 10 is fixed to the inner cavity of the slide groove 7, and the other end of the support spring 10 is fixed to the surface of the slider 8, a reciprocating motion component 11 is provided in the inner cavity of the fixed frame 5, and a traction ring 12 is installed on the surface of the reciprocating motion component 11, a wire is wound around the outer side of the winding roller 4, and the end of the wire away from the winding roller 4 passes through the fixed frame 5 and extends outward;

The slider 8 is driven by the support spring 10 to move in the inner cavity of the slide groove 7, so that the pressure roller 9 is fitted to the guide roller 6, and the wire is limited and pressurized to prevent the wire from loosening, so that the wire has a certain tension. After the winding roller 4 winds up the wire, the wire can be continuously conveyed in the direction of the winding roller 4, and the sudden reduction of the wire tension of the winding roller 4 can be avoided, resulting in the overall loosening of the wire, causing the tension of the subsequent wire winding to change. At the same time, the pressure roller 9 and the guide roller 6 can limit the reverse movement of the wire to ensure the uniform tension of the wire groove.

The reciprocating motion component 11 includes a driving motor 111 fixed to the surface of the fixed frame 5. The output shaft of the driving motor 111 passes through the inner cavity of the fixed frame 5 and is fixed with a screw 112. The screw 112 rotates in the inner cavity of the fixed frame 5 through a bearing. The outer side of the screw 112 is threadedly connected to a moving block 113 through a screw sleeve. The traction ring 12 is fixed to the bottom of the moving block 113. The driving motor 111 drives the screw 112 to rotate, and then the screw 112 drives the moving block 113 to reciprocate back and forth in the inner cavity of the fixed frame 5 through the screw sleeve, so that the wire can be guided by the traction ring 12 to avoid the wire always being wound on the same side of the outside of the winding roller 4, thereby ensuring the neatness of the wire winding.

A guide groove 13 is provided at the top of the inner cavity of the fixed frame 5, and the moving block 113 penetrates into the inner cavity of the guide groove 13 and slides in the inner cavity of the guide groove 13. The setting of the guide groove 13 facilitates the limiting of the moving block 113 to prevent the moving block 113 from rotating with the screw 112 and affecting the stability of the traction ring 12.

The inner cavity of the fixed frame 1 is hinged with a limit plate 14 through a hinge, one side of the limit plate 14 is in contact with the surface of the winding roller 4, and a limit spring 15 is fixed to the side of the limit plate 14 away from the winding roller 4. The side of the limit spring 15 away from the limit plate 14 is fixed to the inner cavity of the fixed frame 1, and the limit plate 14 is supported by the limit spring 15 so that the limit plate 14 is in contact with the outer side of the winding roller 4 to prevent the wire from loosening.

A through hole 16 is provided at the center of the limiting plate 14, and a connecting rod 17 is movably inserted into the inner cavity of the through hole 16. Through the setting of the through hole 16, multiple groups of limiting plates 14 can be conveniently connected into a whole using the connecting rod 17, so that the length of the limiting plate 14 that fits the wire can be adjusted.

The outer side of the guide roller 6 is provided with a rubber sleeve 18, and the rubber sleeve 18 is located on the inner side of the pressure roller 9. The setting of the rubber sleeve 18 increases the friction between the guide roller 6 and the wire to prevent the wire from moving on the guide roller 6. Increasing the friction can maintain a certain resistance to prevent the wire from shrinking.

A ratchet 19 is fixed to the outside of the guide roller 6, and a pawl 20 installed in the inner cavity of the fixed frame 5 is meshed on the outside of the ratchet 19. The setting of the ratchet 19 and the pawl 20 facilitates the limiting of the rotation direction of the guide roller 6 to prevent the end of the wire away from the winding roller 4 from being suddenly tensioned, causing the guide roller 6 to reverse.

During specific use, the wire passes through the guide roller 6 in sequence and then is wound around the winding roller 4 through the traction ring 12. Subsequently, according to the length of the winding roller 4, the number of limit plates 14 connected to the connecting rod 17 is adjusted so that the limit plates 14 connected as a whole are fitted to the outer side of the winding roller 4 under the support of the limit spring 15. Then the driving motor 2 is started, and the output shaft of the driving motor 2 drives the winding roller 4 to rotate and wind the wire through the winding shaft 3. The supporting spring 10 supports the slider 8 so that the slider 8 slides in the inner cavity of the slide groove 7, and the support roller 9 is fitted with the guide roller 6, so that the wire is clamped between the pressure roller 9 and the guide roller 6 to prevent the wire from being conveyed in the reverse direction. Due to the increase in the contact area between the wire and the guide roller 6, the friction force increases, and the winding roller 4 cannot be reversed due to the action of the ratchet 19 and the clamping claw, which can effectively move the wire in the reverse direction, causing the problem of different wire tension.

Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
