The present invention, relates generally to a roiled material, slitting equipment and more particularly to a one-to-many length adjusting equipment which is applied after the material is slit.
Slitter rewinder is an equipment used for slitting roll of material vertically into multiple narrower strips according to the specified width and rewinding such narrower strips of material according to the specified lengths. It is commonly used in slitting cloth and plastic film, etc.
Generally, during the process of rewinding the strips of material one servomotor is used to control multiple rewinding shafts. Yet, since the rewinding shafts are in different positions, some rewinding shafts may finish rewinding earlier than others but keep operating till all other shafts finish rewinding, resulting in rewinding extra scraps.
To solve the above-mentioned problem, the technology of the present invention designs a length, adjusting device between the slitting device and the rewinding device. Said length adjusting device comprises of: a mount and an adjusting unit fixed on the mount. Said adjusting unit comprises of: at least a group of guide rolls end each group of guide rolls comprises of two parallel primary guide rolls and at least one secondary guide roll between the two primary guide rolls and below the two primary guide rolls.
The slitter re winder (100) shown in
A length adjusting device (50) is set between said slitting device (20) and said rewinding device (30). The length adjusting device (50) comprises of: a mount (4) and an adjusting unit 5 fixed on the mount (4). Said adjusting unit (5) is designed for adjusting the strips of material so that they can arrive at the corresponding rewinding group (3) at the same time. Said adjusting unit (5) comprises of: at least a group of guide rolls (51) and each group of guide roils (51) comprises of two parallel primary guide rolls (511) and at least one secondary guide roll between the two primary guide rolls (511) and below the two primary guide rolls (511). Particularly, at least two secondary guide rolls (512) should be configured and the guide rolls (512) should be aligned end to end.
As shown in
As shown in
For example, the strips of material A01-A04 are corresponding to the positions of the rewinding group (3) shown in
In the case above, if over two groups of guide rolls (51) are configured, they should be aligned side to side and the second group of guide roils 51 should at least have one guide lead roll (52). If there are over two lead roils (52), they should be aligned end to end.
The configured quantity of the above-mentioned group of guide rolls (51) is determined based on the quantity of the rewinding shafts (32) and the positions of such rewinding shafts (32). Additionally, at least one lead roll (52) should be configured between two groups of guide rolls (52) to ensure the ends of strips of material can arrive at the rewinding shafts (32) at different positions at the same time.
The above-mentioned substrate 1 is set at one side of the rewinding group (3) correspondingly and has press wheel group (11) designed for leading the strips of material to the rewinding group (3). Through the press wheel group (11), the strips of material before rewound by the rewinding group (3), are properly rewound by the rewinding shafts (32) based on the width of such strips of material to prevent the strips of material from crowning in rewinding. The rewinding diameter of press wheel group (11) is in linear variation according to the diameter of strips of material so that the strips of material are neatly aligned without shedding, which further raises the yield of operation.
Moreover, said substrate (1) at one side of the rewinding group (3) correspondingly at least has one lead roll (12) for leading strips of material.
The above-mentioned rewinding device (30) has another embodiment. As shown in
Further, said control device (40) is a programmable logical controller installed at one side of the feeding device (10). It is designed for controlling the feeding device (10), the slitting device (20), the turnabout and rotation speed of the rewinding motor (33) as well as the power-take-off (PTO) value.
Additionally, the feeding device (10) has multiple control roll for tension control and has a main servo transmission to send the roll of material to the slitting device (20) for slitting. The feeding device (10) also has a pneumatic cylinder and pressure wheels. The pneumatic cylinder is used for driving the pressure wheels pressing the roll of material to prevent the roll of material from sliding in the transmission operation of the main servo transmission, in addition, there is a tension sensor designed for measuring the tension of roll of material. In case of low or high, tension, the corresponding signals will be sent to the control device (40) to ensure the appropriate tension of the roll of material.
The rewinding device (30) of the present utility model comprises of a substrate (1), several rail groups (2) mounted on the substrate (1) and several rewinding groups (3) on the substrate (!) and corresponding to the rail group (2).
As shown in
The above-mentioned movable set: (323) consists of a locating kit (3231) connected to the other side of the locating shaft (322) and a movable kit (3232) put on the locating shaft (322) and between such locating kit (3231) and the clamp set (324). In addition, said locating shaft (322) has a sleeve (326) between the coupling shaft (321 and the clamp set (324).
The above-mentioned rewinding group (3) has a transmission gear (34) between the rewinding shaft (32) and the rewinding motor (33). The transmission gear (34) includes a slave gear (341.) connected to the rewinding shaft (32) and a master gear (342) connected to the rewinding motor (33).
As shown in
The above only describes some exemplary embodiments of the present invention. Those having ordinary skills in the art may also make many modifications and improvements without departing from the conception of the invention, which shall all fall within the protection scope of the invention.
