Description

Winding machine

technical field

The invention relates to a winding device for collecting a flexible sheet to make a roll (material roll), in particular to a winding machine adopting friction winding.

Background technique

Winding equipment, especially winding machines for flexible sheets such as nonwovens, must have the following basic functions: 1. Ensure that the material to be rolled is continuously wound at a constant speed and tension; 2. Replace the winding mandrel under the condition of changing the speed; 3. There is a large enough package capacity (generally, the package diameter is required to be at least greater than 800mm). There are mainly two types of winding machines currently used, one type uses a winding mandrel to directly drive winding, and the other type is friction winding. Because when an object rotates at a certain speed, the farther away from the axis, the greater the linear velocity, so when the winding mandrel is used to directly drive the winding, in order to ensure that the linear velocity of the material during the winding process remains unchanged and is collected The tension of the material remains constant, and the speed of the winding mandrel must decrease accordingly as the diameter of the package increases, resulting in complex structures and complex controls for this type of equipment. Friction winding, one or two friction rollers with constant surface speed friction drive the winding mandrel to rotate, and the rolled material is made into a roll. The speed of the rolled material is determined by the surface speed of the friction roller, which is different from the coil The installed diameter has nothing to do with it. Therefore, compared with the direct drive method of the winding mandrel, the structure and control of the winding mechanism are greatly simplified.

There are two types of friction coiling: single-roller friction and two-roller friction. The main difference in function is that the single-roller type can obtain two or more stations, and it is relatively easy to complete automatic changeover under the condition of constant speed. The action of the roller; two-roller friction winding, the package is always placed on a pair of friction rollers, and the force on the winding shaft core and shaft head is small. Obviously, a smaller diameter winding mandrel can be used to obtain better Large rolls.

However, when single-roller friction or direct drive of the winding mandrel is used, the winding mandrel always bears the weight of the package during the whole process, and this load basically acts on both ends of the winding mandrel. Unreasonable, the result is that either the allowable package diameter is small, or the diameter of the winding shaft must be increased, which cannot meet the requirements of downstream users for package size and winding mandrel diameter.

If two-roller friction winding is used, there is only one station, and the machine must be stopped to replace a new mandrel. Generally, it cannot be used in a continuous production line.

Detailed ways

In the embodiment shown in Figure 1, the winding machine is provided with two groups of friction rollers, and each group of friction rollers is composed of two friction rollers 1, 2 or 3, 4 respectively, which respectively constitute the first station friction rollers 1, 2 and the second Two-station friction rollers 3 and 4, two groups of friction rollers are arranged in parallel on a plane, driven by their respective driving mechanisms (not shown in the figure), and the speed of the four friction rollers can be adjusted individually Stop or run alone; the winding mandrel 10 is placed on one of the friction rollers at different positions, and the friction roller drives the winding mandrel to rotate; two translatable wallboards 7 with vertical slideways 11 are respectively placed on the The two ends of the winding mandrel 10 are driven by a translation device (not shown in the figure) to move in the horizontal direction. When winding, the mandrel shaft head 12 is movable and placed in the vertical slideway 11, and the mandrel 10 can slide vertically. Road 11 moves up and down, and the distance between the two translatable wallboards 7 is equal to the length of the winding mandrel 10, so that the winding mandrel 10 placed here cannot move axially; There is a transverse cutter guide mechanism 5, and a transverse cutter 6 that can move along the axial direction of the friction roller is installed on the guide mechanism 5; a spare winding mandrel feed mechanism ( not shown in the figure).

As shown in Fig. 2, Fig. 3 and Fig. 4, in this embodiment, the vertical slideway 11 consists of two movable guide blocks 8 which are placed in the translatable wallboard 7 and which can reciprocate along the axis of the winding mandrel 10. When the movable guide block 8 pops out of the inner plane of the translatable wallboard 7, the two movable guide blocks 8 form a vertical slideway 11 with the same width as the diameter of the winding mandrel shaft head 12, and the winding mandrel shaft head 12 moves placed in the vertical slideway 11. Of course, the vertical slideway can also be formed in other ways.

The working principle and process of the present invention: as shown in Figure 1, the winding mandrel 10 is placed between the two rollers 1 and 2 of the friction roller at the first station, and the flexible material 9 to be rolled is manually introduced to the winding mandrel for the first time 10, after the winding machine is started, according to the instruction of the electrical control, the movable guide block 8 is in the position shown in Figure 4, and the inner plane of the translational wallboard 7 is ejected to form a diameter equal to the diameter of the winding mandrel shaft head 12. The vertical slideway 11, the vertical slideway 11 limits the radial movement of the winding mandrel 10, and the winding mandrel 10 can move up and down along the vertical slideway 11. According to the instruction of electric control, the friction rollers 1 and 2 of the first station rotate, and the speed is adjusted to a specified value. Driven by the friction rollers 1 and 2, the material is wound onto the winding mandrel 10 at a constant speed. As the diameter of the roll increases, the winding mandrel 10 moves up along the vertical slideway 11 formed by the movable slider 8 but leans against the friction roller 1 and the friction roller 2 all the time. When the winding length is close to the set length, according to the instruction of electric control, the friction rollers 3 and 4 at the second station will be started, and the speed will automatically rise to the same speed as that of the friction rollers 1 and 2 at the first station, and then placed on both sides. The translatable wallboard 7 slowly moves forward under the action of the translation device (not shown in the figure), and the movable guide block 8 exerts a radial force on the rolling roll, which pushes the rolling roll to rub against the second station Rollers 3 and 4 move in the direction, during which the roll can move freely in the vertical direction, and its own gravity can ensure that the moved roll always leans against the surface of a certain friction roller during the whole process of movement, thus ensuring the coiling during movement. The speed does not change. When the roll is moved between the two rollers of the friction rollers 3 and 4 at the second station, the wallboard 7 can be positioned in translation, and the rolled roll is shown as 13 in Figure 1, which is called a completed roll, and the winding mandrel 10 is here Continue winding at constant speed. At this time, the spare winding mandrel feeding mechanism (not shown in the figure) acts, and the spare winding mandrel is sent between the two rollers of the friction rollers 1 and 2 at the first station to form a new mandrel to be wound. 10. The roll material is now located above the friction roller and below the winding mandrel 10 to be rolled. Then the transverse cutter guide mechanism 5 located between the two groups of friction rollers rises, and the transverse cutter 6 moves quickly along the transverse guide rail of the guide mechanism 5, and cuts the roll material along the transverse direction, and the cut material to be rolled is placed in the first position. The adhesive tape on the winding mandrel 10 to be rolled between the station friction rollers 1 and 2 is brought to the winding mandrel 10 to be rolled, and the coiling of a new roll is started. Subsequently, the transverse cutter guide mechanism 5 descends, and the transverse cutter 6 Return, the friction rollers 3 and 4 of the second station stop, and the movable slider 8 on the translatable wallboard 7 is retracted to the position shown in Figure 2, so that there is no protrusion on the inner surface of the translatable wallboard 7, and then it can be translated Wallboard 7 reversely moves, returns to be positioned at the initial position of winding mandrel 10 two ends, after positioning, movable slide block 8 pops up, and the axle head 12 of winding mandrel 10 is locked in the vertical slideway 11. At this point, a complete coiling, cutting, and automatic roll changing operation is completed, and the winding machine enters the next coiling, cutting, and automatic roll changing cycle. The above process is automatically controlled by the electrical control cabinet installed in the winding machine.
