Description

Winding device

Technical field:

The utility model relates to the technical field of devices for winding materials, in particular to a winding device.

Background technique:

In industrial production, it is often encountered that materials need to be rewound, and many production equipment also have reeling devices. The existing reeling devices have roughly the same structure, including a rotating shaft, and a reeling drum is sleeved on the rotating shaft. , use the motor to drive the rotating shaft to rotate, so as to drive the coil to rotate, so as to wind the material on the coil. The use effect of existing coil material device is not good. Some coiling devices are used in conjunction with the unwinding device, and are driven by a motor. When the material is wound to a certain extent and the outer diameter becomes larger, the linear speed of the coiling drum will change at this time, and it will no longer be the same as The unwinding device is synchronized, which affects the subsequent winding action; in addition, when the material is rewound more and the outer diameter becomes larger, it is easy to slip between the reel drum and the rotating shaft, and it is difficult for the rotating shaft to drive the reel drum to rotate. Coil materials need to consume more energy to complete the winding work.

Utility model content:

The purpose of this utility model is to provide a winding device for the deficiencies of the prior art, which can adjust the rotating speed according to the degree of winding materials, and can also adjust the connection with the winding drum, which is very convenient to use.

In order to achieve the above object, the utility model adopts the following technical solutions:

It includes a rotating shaft, on which there is a coil holder; a rotating sleeve is set on the rotating shaft, and the rotating sleeve is connected with an external chain; a rotating disc is installed on the rotating shaft, and there is a friction plate between the rotating disc and the rotating sleeve. ; A knob is threadedly connected to the rotating shaft, and a spring is clamped between the knob and the rotating disk.

Extrusion bars are hinged on the reel holder, and the reel holder is equipped with a movable rod, one end of the movable rod is located inside the reel holder, and the other end of the movable rod is located outside the reel holder. And it is connected with a handle, and the middle part of the movable rod is threadedly connected with the reel drum fixing frame.

The contact surface between the extrusion bar and the movable rod is an inclined plane.

The beneficial effect of the utility model is that according to the winding degree of the material, the friction force between the rotating disc and the rotating sleeve can be adjusted by rotating the knob, so as to achieve the purpose of adjusting the linear speed of the coil material drum, the operation is convenient, and the use effect is better. good.

Detailed ways:

Below in conjunction with accompanying drawing, the utility model is further described.

The following descriptions are only preferred embodiments of the present utility model, and therefore do not limit the protection scope of the present utility model.

See accompanying drawing 1, 2, the utility model comprises rotating shaft 1, and coil material drum fixing frame 2 is arranged on rotating shaft 1; The rotating sleeve 3 is connected with the external chain, and the motor drives the rotating sleeve 3 to rotate through the chain, but does not drive the rotating shaft 1 to rotate; the rotating shaft 1 is also equipped with a rotating disc 4, and the rotation of the rotating disc 4 can drive the rotating shaft 1 to rotate, and the rotating disc There is a friction plate 5 between 4 and the rotating sleeve 3; a knob 6 is threadedly connected to the rotating shaft 1, and a spring 7 is sandwiched between the knob 6 and the rotating disk 4, and the tension of the spring 7 can be adjusted by rotating the knob 6, and then the tension of the spring 7 can be adjusted. The degree of fit between the rotating disc 4 and the friction plate 5 , that is, the friction force between the rotating disc 4 and the friction plate 5 can be adjusted. When starting to rewind the material, the linear speed of the reel is relatively small, and the knob 6 can be adjusted to make the friction between the rotating disk 4 and the friction plate 5 smaller. When the material is rewound more and the outer diameter becomes larger, the If the linear velocity of the barrel becomes smaller, the knob 6 can be adjusted to increase the friction between the rotating disk 4 and the friction plate 5, so that the external chain can fully drive the rotating shaft 1 to rotate through the friction plate 5 and the rotating disk 4, and then Increase the linear speed of the reel to ensure synchronization with the unwinding device.

Extrusion bar 8 is hinged on the described reel holder 2, and reel holder 2 is equipped with movable rod 10, and one end of movable rod 10 is positioned in reel holder 2, and the other end of movable rod 10 It is located outside the reel holder 2 and is connected with a handle 9, and the middle part of the movable rod 10 is threadedly connected with the reel holder 2; the contact surface between the extruding bar 8 and the movable rod 10 is an inclined plane; Make the movable rod 10 move relative to the reel barrel fixed mount 2, as shown in Figure 2, if the movable rod 10 moves outwards, then one end of the extruded bar 8 can be pushed outwards, thereby the coil can be drawn from the center of the reel. The material barrel is stuck, which can increase the connection between the winding material barrel and the rotating shaft 1, and even if there are many materials to be rolled, the smooth winding of the materials can be ensured.

The utility model has a wide application field and can be applied to industrialized production.

The utility model has the advantages of simple structure, good use effect and the like.
