As shown in fig. 4, the film rolling detection device 9 includes a first film rolling sensor disposed beside the first film rolling mechanism 2 and a second film rolling sensor disposed beside the second film rolling mechanism 3, and when the running film roll is about to run out, the sensors sense and start to trigger the automatic splicing film mechanism 1 to work.
When the full-automatic film receiving device works, as shown in fig. 5a, the first film winding mechanism 2 firstly performs film releasing, and the film on the first film winding mechanism 2 is used as a working film and is output by bypassing the first turnover mechanism 13 of the automatic splicing film mechanism 1. Simultaneously, the initial end of the film on the standby second film rolling mechanism 3 is pulled out of the 1/2 width of the adhesive tape 18 stuck on the adsorption surface F, the other 1/2 width of the adhesive tape 18 is reserved, and at the moment, the first turnover mechanism 13 and the second turnover mechanism 15 of the automatic splicing film mechanism 1 are respectively positioned at the positions B and A; turning the handle on the second turning mechanism 15 to the position B (see FIG. 5B), triggering and starting the automatic film splicing mechanism 1 when the first film rolling sensor senses that the rolled film is used up quickly, and driving the film cutting knife 123 to move along the film width direction by the film cutting cylinder 121 of the film cutting mechanism 12 to cut off the first film roll 22 at the adsorption surface F of the first turning mechanism 13; then as shown in fig. 5c, the first film combining cylinder 16 pushes the film end adsorbed on the movable vacuum tube 134 of the first turnover mechanism 13 to be pressed onto the other 1/2 adhesive tape 18 of the opposite second turnover mechanism 15, and the adhesive tape 18 bonds the tail end of the working film and the head end of the new film to be connected together, so as to finish film connection; then, the first film combining cylinder 16 and the movable vacuum tube 134 of the first turnover mechanism 13 are reset, and the second film rolling mechanism starts to work; and then the new first film roll 22 is replaced, the first turnover mechanism 13 is rotated to the position A, the initial end of the first film roll 22 is pulled out of the 1/2 position of the adhesive tape 18 stuck on the silica gel plate 141 of the first turnover mechanism 13, the first turnover mechanism 13 is rotated to be positioned at the position B, when the second film roll sensor senses that the film roll is used up soon, the automatic splicing film mechanism 1 is triggered to start, the second film roll splicing action is completed by the film shearing mechanism 12 and the second film combining cylinder 17, and after the completion, the first film roll mechanism 2 starts to work, and the new second film roll 32 is replaced. The above is a complete working cycle of the splicing membrane mechanism, and then the cycle is repeated continuously, so that the function of automatic splicing membrane is realized.
When the first turnover mechanism 13 and the second turnover mechanism 15 are at the preparation position A, the adsorption surface F faces outwards, the operation space for arranging the adhesive tape 18 and pasting the new film rolling starting end is larger, and the operation is more convenient; then, when the film is transferred to the film-connecting position B, the film-connecting operation is more convenient, and the film-connecting action is more accurate and reliable.
When the full-automatic film shearing device works, the film rolling detection device 9 can automatically detect that the film roll of the film rolling mechanism is about to run out, trigger the film shearing mechanism 12 of the automatic film splicing mechanism 1 to cut off the film in operation, the film closing cylinder pushes the tail end of the cut film to the adhesive tape 18 adhered with the starting end of the new film roll, the film receiving operation is automatically completed, the new film roll starts to work, and the whole film shearing, pressing and film receiving operation is automatically completed without stopping operation, so that manual operation is not required, and the efficiency is higher.
The full-automatic film receiving device of the second embodiment further comprises a film hanging roll mechanism 4 on the basis of the first embodiment. Because the film roll is very heavy, the manual moving up and down is very difficult, and the film roll hanging mechanism 4 can automatically load and unload the film roll, so that the manual moving is omitted and the efficiency is high.
As shown in fig. 1, the film winding mechanism 4 includes a film winding lifting motor 41, a chain transmission mechanism 43, and a hook. The film winding lifting motor 41 is arranged in the middle of the top of the full-automatic film receiving device, and drives two groups of chain transmission mechanisms 43 on two sides and lifting hooks below through a transverse main shaft 42. The chain transmission mechanism 43 comprises a chain wheel, a chain drum and a roller, and the two groups of chain transmission mechanisms 43 are respectively positioned outside the first base plate 7 and the second base plate 8.

As shown in fig. 1, the film winding buffer mechanism 5 is located behind the first film winding mechanism 2 and the second film winding mechanism 3, mounted on the first substrate 7 and the second substrate 8, and disposed from top to bottom.
Because the film winding mechanism is used for continuously releasing the film, the film used in the subsequent process of the full-automatic film receiving device is intermittent, namely: film releasing, stopping and releasing, and the film continuously sent by the film winding mechanism needs to be temporarily stored in a film winding buffer device and then output when required. The film winding buffer device is required to complete the actions of film storage and film feeding.
As can be seen from fig. 6, the running film roll is pulled and wound on nine rollers mounted on the upper film storage fixing frame 53 and the lower film storage moving frame 54 by the film winding mechanism and the film automatic splicing mechanism 1 through the film stopping mechanism 51 of the film winding buffer device, and is output after being driven by the film picking mechanism 56 and the servo motor 59.
The motor of the film storage moving mechanism 55 is arranged above the substrate, and the motor is controlled to drive the transmission mechanism to drive the lower film storage moving frame 54 to move up and down according to the signal from the electric eye detection device 60; the film picking mechanism 56 consists of a cylinder and a pair of gears, and the cylinder can drive the gears to pull the film between the gears; the servo motor 59 also drives the driving rubber roller 57 and the driven rubber roller 58 to drive the film therebetween to act. When the film storage moving frame 54 moves downwards, the film storage moving frame moves upwards, and the film selection mechanism 56 and the servo motor 59 cooperate with film feeding, so that the film feeding and drawing work is completed.
The film winding buffer mechanism 5 further comprises a cursor detection device 52, which is arranged in front of the film stopping mechanism 51 and is used for detecting a bag width signal. The inflatable shaft 21 of the film roll is provided with corresponding scales, and can be widely applied to the molding requirements of packaging bags with different widths.
The device can be matched with a bottom punching device and a plastic bag forming device, is suitable for the bag making and forming requirements of most plastic packaging bags in the current market, and has wide application range.
