The working principle of the invention is as follows:
(1) cutting off a new film: manually and tidily placing the head of the new membrane on the new membrane cutting plate 2, then pressing the new membrane pressing plate 3 forwards, and tidily cutting off the head of the new membrane from the transverse membrane cutting long groove by using a handheld cutter;
(2) two sides of the new film are in a Y shape: manually pushing the cut new film forwards to enable the front end of the new film to exceed the front end of the middle supporting plate 4A by a proper distance, descending the middle pressing plate 47 to tightly press the new film on the middle supporting plate 4A, and manually placing the upper and lower M-shaped edges at two sides of the new film on the upper and lower sides of the Y-shaped template respectively;
(3) cutting off the old film: when the used film of the FFS packaging machine is used up, the packaging machine stops running, the side shaping plates 162 on the left side and the right side move inwards to center the used film, the film clamping grippers 183 on the left side and the right side are closed to clamp two sides of the used film to prevent the used film from moving forwards and backwards, then the compressing mechanism 5 on the used film and the compressing mechanism 11 under the used film swing to be closed to clamp the used film, and the used film cutter 13 in the transverse long groove of the used film pressing plate 51 moves transversely to cut off the used film;
(4) opening the old film: the new film transverse moving mechanism transversely moves the new Y-shaped film to the old film position, meanwhile, the upper film opening heat-sealing mechanism 6 and the lower film opening heat-sealing mechanism 12 swing to be closed, the upper old film pressing mechanism 5 and the lower old film pressing mechanism 11 swing to be opened, the film opening sucker 61 sucks the old film, then the upper film opening heat-sealing mechanism 6 and the lower film opening heat-sealing mechanism 12 swing to be opened, and the end opening of the old film is opened in an M shape in an up-and-down parallel mode;
(5) inserting the Y-shaped new membrane into the M-shaped old membrane: the film feeding cylinder 49 drives the film feeding portal frame 48 to move forwards to drive the Y-shaped plates 42, the middle pressing plate 47, the middle supporting plate 4A and the Y-shaped new films on the left side and the right side to also move forwards, the Y-shaped new films are inserted into the old films which are opened into M shapes, the upward film opening heat sealing mechanism 6 and the downward film opening heat sealing mechanism 12 swing and close to press the front ends of the new films, the middle pressing plate 47 rises to loosen the new films, the film feeding cylinder 49 drives the film feeding portal frame 48 to move backwards and reset, and then the Y-shaped plate cylinders 43 on the left side and the right side drive the Y-shaped plates 42 to move outwards to enable the Y-shaped plates 42 to be separated from the M-shaped edges on the two sides of the new films;
(6) heat-sealing the new and old cylindrical films: the upper film heat sealing mechanism 6 and the lower film heat sealing mechanism 12 are swung to be opened, the upper pressing mechanism 5 and the lower pressing mechanism 11 on the old film are swung to be closed, so that the splicing position of the new film and the old film is smooth and free of wrinkles, then the upper film heat sealing mechanism 6 and the lower film heat sealing mechanism 12 are swung to be closed, the heat sealing mechanism 66 is heated, two layers of films between the new cylindrical film and the old cylindrical film are heat-sealed together, the sealing cooling air pipe 67 blows cold air to cool and solidify the heat-sealed position, then the pressing mechanisms and the film heat sealing mechanisms are both opened, the edge separating air cylinders 175 on the left side and the right side drive the edge separating plate 174 to move backwards in place and then return, the upper edge and the lower edge of the M shapes on the two sides of the old film are prevented from being bonded together, the last side shaping plate 162 is reset, the film clamping gripper 183 is opened, and the automatic film connecting work is completed.
(7) Treatment of failure of membrane connection: if the film splicing failure is found, the heat-sealing position needs to be cut off and butted again, at the moment, the clamping plate mounting carrier roller 186 is manually taken down, the cached old film is convenient to move backwards, the film clamping grippers 183 are closed to grasp two sides of the film, the swinging air cylinder 184 drives the film clamping grippers 183 to swing upwards for a certain distance, the new film and the old film are manually pulled backwards, the heat-sealing position is located behind the old film cutter 13, then the steps (1) to (6) are carried out again, the automatic film splicing operation is completed, and finally the clamping plate mounting carrier roller 186 is mounted and reset.
The invention has the beneficial effects that:
A. after the new film is manually arranged into a Y shape and clamped and kept in the shape, the new film is inserted into the opened old film in an integral clamping and transferring mode, the problem of insertion failure caused by downward bending of the front section of the new film is avoided, and the success rate of automatic film connection is improved.
B. The mode that the old membrane opening is opened in parallel from top to bottom is adopted, so that the opening size of the old membrane opening section is consistent from front to back, the problems of bending and wrinkling caused by the fact that the front end of a new membrane touches the inner side of the old membrane are avoided, and the heat sealing position is smoother.
C. Before the hot sealing of the new and the old films after the insertion, the Y-shaped plates on the left and the right sides move outwards to be completely separated from the new films, so that the insertion positions of the new and the old cylindrical films can keep flat shapes after the upper and the lower pressing mechanisms are closed, and a good hot sealing effect and a smooth butt joint effect are achieved.
D. The old film opening sucker is positioned between the old film pressing plate and the heat sealing mechanism, and the sucker is positioned closer to the opening of the old film, so that the problem that the opening is bent downwards when the old film is sucked and opened is solved, and the reliability of the device is improved.
E. The left and right side shaping plates are used for centering the old film before splicing, so that left and right dislocation of the new film and the old film during splicing is avoided, and successful splicing is ensured.
F. The two sides of the old film are gripped by the film clamping grippers, so that the old film can be prevented from accidentally moving in the butt joint process, and the success rate of film splicing is improved.
G. The film and the clamp plate installation type carrier roller of the buffer memory can be used for rapidly and conveniently processing the failure of film connection, and the working efficiency of automatic film connection is improved.
