Problems solved by technology

[0004] When the adhesive film exits from the unwinder to the subwinder, the adhesive film often deviates, causing the two ends of the divided film roll to have a gyro effect, which affects the cross-cutting quality. Even wasteful (usually both ends of the small roll are discarded during cross-cutting)
[0005] In order to prevent the deviation of the adhesive film as far as possible in the prior art, the tension of the adhesive film is increased. It is proved that this method not only increases the complexity of the equipment, but also works better than nothing

Embodiment

[0024]See figure 1 , a machine base 1 is given, and the machine base 1 may also be called a base or a chassis. Depend on figure 1 It can be seen from the schematic diagram that the base 1 is composed of a pair of base arms 11 parallel to each other, a base arm connecting beam 12 for connecting the pair of base arms 11 into a solid overall structure, and a film guide frame 14. front and rear ends of arm 11 ( figure 1 Shown position state) each constitutes promptly respectively offers a wallboard roller groove 111, and the function of this wallboard roller groove 111 will also be described below. The film guide frame 14 is corresponding to the rear end of a pair of base arms 11 ( figure 1 The shown position state is taken as an example), an upper film guide roller 142 is rotatably arranged on the upper part of the film guide frame 14, and a lower film guide roller 143 is rotatably arranged on the lower part, and a film guide roller 143 is arranged on the right side of the fil...

Abstract

The invention provides a film uncoiling machine having an automatic deviation rectifying function and belongs to the field of special devices for film adhesive tape production. The film uncoiling machine comprises a machine base, wherein the machine base comprises a pair of base arms, a base arm connecting beam, a film guiding frame, a pair of wall boards, a supporting roller driving mechanism, a supporting roller lifting power mechanism, a traction transmission shaft, a supporting roller traction mechanism and a supporting roller. The film uncoiling machine is characterized in that wall board rolling wheel grooves are respectively formed at the front ends and the rear ends of a pair of base arms. Wall board rolling wheels are respectively arranged at the front ends and the rear ends of a pair of wall boards and correspond to the wall board rolling wheel grooves and matched with the wall board rolling wheel grooves. A deviation rectifying execution mechanism is arranged on the base arm connecting beam and connected with one inward side of one wall board. A film deviation signal acquirer is arranged on the film guiding frame. When a film deviates, the film deviation signal acquirer acquires signals, the deviation rectifying execution mechanism drives the wall board rolling wheels on a pair of wall boards to perform displacement along the wall board rolling wheel grooves so as to achieve deviation rectification, and a phenomenon that two ends of each split film roll protrude.

Description

technical field [0001] The invention belongs to the technical field of special equipment in the production of film adhesive tapes, and in particular relates to a film unwinder with automatic deviation correction function. Background technique [0002] The film mentioned above mainly refers to but not only refers to adhesive tapes (that is, adhesive films, the same below), adhesive tapes such as various types of masking tapes including light-shielding tapes, for which you can refer to CN101245226A disclosed in Chinese patent literature (a new light-shielding tape), CN202626083U (light-transmitting tape), CN202808680U (tape for liquid crystal display modules), CN202808683U (light-shielding reflective tape for electronic products), CN202808684U (light-shielding double-sided tape for electronic products) and CN102149780A (covering strip of PVC film), etc. [0003] Taking the technical content disclosed in the "PCB board light-shielding tape and its preparation method" recommend...
