Description
Technical Field
The invention belongs to the technical field of foil winder equipment, and particularly relates to a winding pressing device for foil winding equipment and a winding method of foil strip material.
Background
Because the foil winding machine needs to have the compression roller to roll and extrude all the time on the foil winding surface when winding foil strip coil, firstly tightly press current layer foil strip on previous layer foil strip, furthest eliminate the space between foil strip layer and the layer, make the foil strip material roll of coiling more tight, avoid the manual work later stage to fill it as far as possible. Secondly, when the winding of the coil is finished and the foil tape is sheared by the coil, the phenomenon that the wound coil is loosened and separated when tension of the wound coil is lost is avoided. However, as special-shaped products such as ellipses and rectangles exist in the foil coil, namely, the cross section of the foil coil is elliptic or rectangular, the compacting device is required to adapt to the change of the cross section diameter when the non-circular truncated coil rotates, and the effect of rolling along with the shape is achieved. This adds more difficulty to the compaction function in winding.
Most foil winding machines in the current market adopt a simple structure that a straight arm is connected with a press roller. The structure only plays a role in winding and pressing the round foil strip coil in the winding process, but cannot meet the winding and pressing requirements of products with special shapes such as ellipses, rectangles and the like. Because the mould rotates for one period in the coiling process of elliptical and rectangular products, the length of the coiling radius changes periodically, and the movement form of the simple straight arm press roller cannot adapt to the rapid change of the coiling radius of the rectangular mould. Or in the process of rapidly increasing the winding radius, the straight arm press roller cannot be rapidly retracted, so that the press roller arm is broken. Or in the process of rapidly reducing the winding radius, the straight arm press roller cannot rapidly follow and press the surface of the foil strip to form a wrap angle at the edge of the material roll, so that the wrap angle formed by the current layer of foil strip cannot be completely attached to the surface of a die or the previous layer of foil strip, a larger gap is formed at the wrap angle, namely, each layer of wrap angle is bulged, so that the finally wound finished foil strip roll 12 is loosened outwards, the central space of the finished foil strip is enlarged, a larger gap still exists after the iron chip is sleeved, and the finished foil strip needs to be filled in later period manually, thereby greatly influencing the product performance and the production efficiency.

Example 1:
The embodiment provides a coiling closing device for foil winding equipment, including support frame 1, pivot 2, press arm 4 and compression roller frame 5, pivot 2 locate on the support frame 1 and for support frame 1 free rotation, press arm 4 one end is connected with pivot 2, press arm 4 other end and press roller frame 5 are connected, compression roller frame 5 can be for press arm 4 free rotation, be equipped with resilience resetting means 7 between press arm 4 and the compression roller frame 5, pivot 2 is connected with drive arrangement 3, install press roll body 6 on the compression roller frame 5, press roll body 6 contact extrusion is on foil strip roll 12 surface. As shown in fig. 1 and 2.
Taking a rectangular mold as an example, the use process is as follows:
when winding starts, the foil strip head is fixed on the surface of the rectangular die, at the moment, the winding pressing device for the foil winding equipment starts to act, the driving device 3 pushes the rotating shaft 2 to rotate clockwise, the pressing arm 4 presses the whole pressing roller body 6 on the surface of the die around which the foil strip is wound due to the limiting effect of the rebound resetting device 7, and the pressing roller body 6 is the whole formed by three pressing rollers and can rotate freely in the process of contacting with the foil strip coil 12, so that the V-shaped structure formed by any two pressing rollers in the pressing roller body 6 always acts on the surface of the die around which the foil strip is wound without manual intervention on the pressing roller position. The position of the die is adjusted so that the press roller is pressed at the middle position of the short side of the die when the press roller acts for the first time. Adjusting the driving force constant value of the driving device 3; the rebound resetting means 7 are in a stretched state at this time, and thus the roll body 6 generates a predetermined pressure against the foil strip wound around the surface of the mould. The pressure is the pressure required constantly in the foil winding process.
The die starts to rotate, the contact position of the roller body 6 starts to creep from the middle of the initial short side to the long side, namely the turning radius of the die gradually increases, at the moment, the roller body 6 is forced to be far away by reaction, the rebound resetting device 7 is stretched further instantly, meanwhile, the pressing arm 4 rotates clockwise relative to the supporting frame 1 together with the rotating shaft 2, and at the moment, the driving device 3 is forced to retract for a certain stroke;
Wherein the driving device 3 adopts a device capable of providing a stable acting force in the whole course, and the stable acting force of the driving device 3 can enable the press roll body 6 to have a preset pressure which is stable in the whole course to act on the surface of the foil strip until the press roll body 6 reaches the maximum contact radius of the die.
At this time, the roll 6 contacts a wrap angle of the roll 12, the V-shaped structure formed by any two rolls acts on both sides of the wrap angle at the wrap angle of the roll 12, and as the roll 12 rotates, the two rolls roll the wrap angle in sequence, thereby rolling the foil strips at the wrap angle and bending the foil strips at both sides of the wrap angle.
Then, the mold continues to rotate, when the roll body 6 passes through the short long edge position of the rectangular foil strip roll 12, the roll body 6 contacts the other wrap angle of the foil strip roll 12, the two rolls still roll the wrap angle position in sequence, and the foil strips at the wrap angle are folded when rolling the foil strips at the wrap angle.
Thereafter, the contact position of the roll body 6 is crawled from the long side to the short side, i.e. the radius of gyration of the foil strip roll 12 gradually decreases, and the mould around which the foil strip is wound has a tendency to come off the surface of the roll body 6, at which time the rebound resetting means 7 momentarily tend to resume the natural state, causing the press arm 4 to rotate counter-clockwise with respect to the supporting frame 1 together with the rotation shaft 2, the press arm 4 continuing to press the roll body 6 against the mould until the roll body 6 reaches the minimum radius of contact of the mould, which position, i.e. the middle position of the short side of the mould, can be understood as the initial position of the roll body 6 due to the symmetry in the shape of the rectangular mould. So far, the press roll body 6 completes one movement period in the process of winding the foil strip by the rectangular die, and the press roll body 6 completes the two movement periods in the process of winding one circle by the rectangular die. In this analogy, during the winding of a rectangular coil product, the roll body 6 repeatedly completes the above-described movement cycle.
According to the winding pressing device for the foil winding equipment, the press roller frame 5 can rotate freely relative to the press arm 4, and meanwhile, the rebound reset device 7 is arranged between the press roller frame and the press arm, so that the foil strip roll 12 with a special shape, wherein the cross section shape of the die is elliptical or rectangular, can follow the length change of the cross section diameter when the non-circular truncated roll rotates, and plays a role in shape-following rolling.
The driving device 3 provides a stable acting force in the whole process, so that the press roller body 6 has a preset pressure which is stable in the whole process to act on the surface of the foil belt, firstly, the current layer of foil belt is tightly pressed on the previous layer of foil belt, the gap between the foil belt layers is eliminated to the greatest extent, and the wound foil belt roll 12 is further tightly pressed on the foil belt roll 12. Secondly, when the winding of the material is finished and the foil tape is sheared by the winding device, the clamping device can clamp the sheared foil tape head on the surface of the material roll, so that the phenomenon that the wound material roll 12 of the foil tape is loosened and separated when tension of the wound material roll is lost is avoided.
