Description

Technical Field

[0001] The present application relates to a thin strip winding device, which is mainly suitable for material unwinding work. Background Art

[0002] The prior art has the following defects:

[0003] 1. The locking of the receiving barrel needs to be done by manual chuck, which is time-consuming and laborious;

[0004] 2. The winding machine uses a variable frequency motor, and the winding speed needs to be adjusted manually, which cannot ensure accurate synchronization with the unwinding, resulting in inconsistent tightness of the winding coil;

[0005] 3. The coil at the front end of winding is prone to slight jumping and horizontal (front and back) shifting, which may cause the coil to tilt and become uneven during winding. Summary of the invention

[0006] The technical problem solved by the present application is to overcome the above-mentioned deficiencies in the prior art and to provide a thin strip winding device which has a simple structure, is easy to use, can be precisely synchronized in winding and unwinding, and can produce relatively neatly wound materials.

[0007] The technical solution adopted by the present application to solve the above technical problems is: a thin strip winding device, including a frame, a rotary servo motor, characterized in that it is also provided with a tensioning mechanism, a rotary joint, a front and rear driving device, and a deviation correction displacement sensor. The tensioning mechanism is used to fix or loosen the receiving drum, and the front and rear driving devices are installed on the frame, and the frame is provided with a slide rail configured along the front and rear directions, and a slide plate is installed on the slide rail. The slide plate is installed on the slide plate. The rotary joint and the rotary servo motor are installed on the slide plate. The slide plate is connected to the front and rear driving devices, and the main shaft of the rotary servo motor is rotatably installed on the rotary joint. The front end of the main shaft is connected to the tensioning mechanism, and a deviation correction displacement sensor for detecting the position of the receiving drum is provided at the front of the frame. The present application controls the tensioning mechanism to open or close, thereby locking or releasing the receiving drum, reducing manual intervention, saving time and effort; the winding power adopts a rotary servo motor, which is convenient for controlling the synchronization with the unwinding mechanism; the present application uses a deviation correction displacement sensor to detect the change of the receiving drum position at any time, and can timely correct the deviation in the front and rear directions through the front and rear driving devices, so that the coiled material is relatively neat.

[0008] The expansion mechanism includes an expansion cylinder, an expansion sleeve, an expansion connecting rod, a vertical plate, and an arc-shaped winding plate. The expansion cylinder, the vertical plate, and the main shaft are fixedly connected together. The expansion sleeve is slidably sleeved on the expansion cylinder connecting shaft. The expansion sleeve is hinged on the circumferential outer side with several sets of evenly arranged expansion connecting rods. Each set of expansion connecting rods is hinged to an arc-shaped winding plate. All the arc-shaped winding plates constitute a circumferentially opening and closing type receiving barrel fixed sleeve. The tail of the arc-shaped winding plate is stuck in the circumferential movable groove of the vertical plate.

[0009] The expansion link is provided with two sets of bearing groups respectively arranged on both sides of the expansion link, and each bearing group has a bearing respectively arranged on both sides of the vertical plate and in contact with the vertical plate, so that the arc winding plate can only move radially along the circumferential movable groove and move smoothly radially under the action of the bearings of the two sets of bearing groups. The expansion cylinder is actuated to control the expansion sleeve to slide back and forth, thereby driving the expansion link to move. The expansion link drives the arc winding plate connected thereto to move synchronously, that is, to open or close the arc winding plate. The rotary servo motor controls the rotation of the expansion mechanism through the main shaft, thereby driving the receiving drum mounted on the arc winding plate to wind up.

[0010] A graphite sliding sleeve is arranged inside the expansion sleeve, and the graphite sliding sleeve is sleeved on the expansion cylinder connecting shaft, so as to further improve the sliding performance and service life.

[0011] The rotary joint described in the present application is provided with a ventilation cylinder, which is connected to the air supply device through an air inlet annular groove and an air outlet annular groove. The air inlet annular groove and the air outlet annular groove are connected to the main shaft airway of the main shaft, and the front part of the main shaft airway is connected to the tightening cylinder, so that the air supply device drives the tightening cylinder to move through the annular groove and the main shaft airway, thereby preventing the air path and the rotating mechanism from interfering with each other.

[0012] The frame is provided with a pneumatic control rocker, which is used to control the operation of the air supply device. The expansion cylinder adopts a thin cylinder to save space.

[0013] The present application is also provided with a controller, which is connected to the rotary servo motor, the front and rear drive devices, the deviation correction displacement sensor and the unwinding machine servo motor and controls their operations.

[0014] Compared with the prior art, the present invention has the following advantages and effects: simple structure, easy use, precise synchronization of rewinding and unwinding, and relatively neat coils. BRIEF DESCRIPTION OF THE DRAWINGS
