Description

[Technical Field]

[0001] This utility model relates to a shaftless winding device. [Background Technology]

[0002] Existing winding devices generally have a connecting shaft, so the connecting shaft needs to be removed before the winding drum can be put on the connecting shaft to wind up the material, which is cumbersome to operate.

On the other hand, the existing winding device cannot move after it is fixed, and the relative position between the discharge device and the winding device cannot be adjusted, which can easily cause wrinkles when the winding device winds up the material.

[0020] The technical solutions in the embodiments of this utility model will now be clearly and completely described in conjunction with the accompanying drawings.

[0021] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indication will also change accordingly. Furthermore, descriptions involving "preferred," "second-best," etc., in this utility model are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined as "preferred" or "second-best" may explicitly or implicitly include at least one of those features.

[0022] like Figure 1-3As shown, a shaftless winding device includes a base 1, on which a swing arm bracket 2 rotatable is mounted. Two laterally arranged slide rails 3 are respectively provided on the front and rear sides of the swing arm bracket 2. Two sliding seats 4, which can slide along the slide rails 3, are located between the two slide rails 3 on the same side. Slide screw nuts 5 are provided on the inner side of each sliding seat 4. Two slide screws 6 are provided inside the swing arm bracket 2. One slide screw 6 is connected to the slide screw nuts 5 of the two sliding seats 4 located on the front side of the base 1, and the other slide screw 6 is connected to the two sliding seats 4 located on the rear side of the base 1. The base 1 is connected to the slide screw nut 5. A rotatable turntable 7 and a rotating motor that drives the turntable 7 are located on one side of the base 1. The swing arm bracket 2 is connected to the outside of the turntable 7. Two winding shaft length adjustment motor assemblies 8, each connected to a slide screw 6, are located inside the turntable 7. A winding chuck 9 is located on the outer side of the slide 4. The winding chucks 9 on the two slides 4 on the same side are positioned opposite each other. Two winding motor assemblies 10, each connected to a winding chuck 9 on the side closest to the turntable 7, are located on the turntable 7. A base position adjustment assembly is located between the base 1 and the bottom surface to adjust the position of the base 1. In use, the winding shaft length adjustment motor assembly 8 drives the slide screw 6 to rotate. This, in conjunction with the slide screw nut 5, drives the two slides 4 on the same side to move relative to each other, thereby adjusting the relative position of the winding chucks 9 on the two slides 4, thus clamping and releasing the winding drum. After the empty roll is loaded with the winding chucks 9 on both sides, the winding motor assembly 10 drives one of the winding chucks 9 to rotate, thereby driving the winding drum to rotate and wind up the roll. After one winding drum finishes winding, the rotating motor drives the turntable 7 to rotate, moving the roll to the empty winding drum on the other side. After the roll is cut, the winding motor assembly 10 drives the empty winding drum to rotate and wind up the roll, realizing the function of alternating winding. On the other hand, when there is a positional deviation between the winding device and the discharge device, the position of the winding device can be adjusted by the machine base position adjustment assembly, thereby adjusting the relative position between the winding device and the discharge device, realizing the function of quick position adjustment, so that the winding drum can wind up better.

[0023] like Figure 1-3 As shown, the swing arm bracket 2 is a U-shaped bracket. Two slide guide rails 3 on the same side are respectively set on the upper and lower sides of the U-shaped bracket. Two slide screws 6 are respectively set inside the U-shaped bracket, which reduces the weight of the swing arm bracket 2 and facilitates the installation of the slide screws 6.

[0024] like Figure 1 As shown, the upper and lower sides of the swing arm bracket 2 are respectively provided with transition rollers 11, which are used for the transition from winding on one side to winding on the other side after winding on the other side is completed.

[0025] like Figure 2As shown, the base 1 is provided with multiple turntable rollers 12 that cooperate with the outer side of the turntable 7, so that the turntable 7 can rotate on the base 1 without the need to set the turntable 7 shaft.

[0026] like Figure 2 As shown, a circular turntable gear 13 is provided on the inner side of the turntable 7 near the edge. A motor drive gear that meshes with the circular turntable gear 13 is provided on the rotating motor shaft, so that the turntable 7 rotates to switch the winding position of the coil.

[0027] like Figure 2 As shown, the winding shaft length adjustment motor assembly 8 is a worm gear reducer assembly, which facilitates accurate adjustment of the relative positions of the two winding chucks 9.

[0028] like Figure 1-3 As shown, the take-up motor assembly 10 includes a three-phase asynchronous motor 101 disposed on the inner side of the turntable 7 and with its shaft extending out of the outer side of the turntable 7. The shaft end of the three-phase asynchronous motor 101 is connected to a motor synchronous pulley 102. The turntable 7 is provided with a synchronous pulley connecting shaft 103 that passes through the turntable 7. The outer end of the synchronous pulley connecting shaft 103 is connected to a first synchronous pulley 104, and the inner end of the synchronous pulley connecting shaft 103 is connected to a second synchronous pulley 105. A first transmission belt 106 is connected between the synchronous pulley connecting shaft 103 and the first synchronous pulley 104. The transmission rod of the take-up chuck 9 near the turntable 7 passes through the turntable 7, extends into the inner side, and is connected to a take-up chuck synchronous pulley 107. A second transmission belt 108 is connected between the second synchronous pulley 105 and the take-up chuck synchronous pulley 107. During winding, the three-phase asynchronous motor 101 drives the motor synchronous pulley 102 to rotate, the first transmission belt 106 drives the first synchronous pulley 104 to rotate, the synchronous pulley connecting shaft 103 drives the second synchronous pulley 105 to rotate, and the second transmission belt 108 drives the winding chuck synchronous pulley 107 to rotate, thereby driving the winding chuck 9 to rotate and wind up the roll.

[0029] like Figure 1-2 As shown, tensioning wheels 14 are respectively provided on the inner and outer sides of the turntable 7 near the first transmission belt 106 and the second transmission belt 108 to adjust the transmission power of the transmission belts.

[0030] like Figure 1-2As shown, the machine base position adjustment assembly includes multiple pulley guide rails 15 mounted on the mounting surface. Multiple pulleys 16, each cooperating with one of the pulley guide rails 15, are located on the lower side of the machine base 1. A locking assembly 17 is provided between the machine base 1 and the mounting surface. The locking assembly 17 includes a fixed base 171 fixed to the mounting surface. A position adjustment motor 172 is mounted on the fixed base 171. An adjusting screw 173 is connected to the rotating end of the position adjustment motor 172. An adjusting screw nut 174, cooperating with the adjusting screw 173, is located on the side of the machine base 1. When adjusting the position of the winding device, the position adjustment motor 172 is controlled to rotate. Through the cooperation of the adjusting screw 173 and the adjusting screw nut 174, the machine base 1 and the pulleys 16 move along the pulley guide rails 15 to adjust the position of the winding device.
