[0023] like Figure 1 to Figure 2 An automatic double-sided film wrapping device is shown, comprising a bottom plate 1 and a film discharging mechanism 2 arranged on the bottom plate 1. The film discharging mechanism 2 is a prior art, which winds the diaphragm on a material roller, flattens the diaphragm through a plurality of pressing rollers and stretching rollers, and finally discharges the diaphragm from a material outlet. The film discharging mechanism 2 is provided with a film cutting device at the material outlet, which cuts the diaphragm after the diaphragm is discharged to a predetermined length.

[0024] A film absorbing plate 3 and a carrier plate 4 are arranged on a bracket in sequence along the discharge direction on the discharge side of the film discharging mechanism 2, and adsorption holes 5 are respectively arranged on the end faces of the carrier plate 4 and the film absorbing plate 3. The bottom of the adsorption hole 5 is connected to a negative pressure air source, which can adsorb the diaphragm located on the carrier plate 4 and the film absorbing plate 3.

[0025] A film pulling mechanism is also provided on the discharge side of the film discharge mechanism 2, and the film pulling mechanism includes a film clamping block 6 which can clamp the diaphragm from the discharge port of the film discharge mechanism 2, and the film clamping block 6 is located above the carrier plate 4 and can reciprocate along the discharge direction of the diaphragm to place the clamped diaphragm on the carrier plate 4 and the film suction plate 3.

[0026] The end of the film absorbing plate 3 close to the carrier plate 4 has a rotation center axis perpendicular to the stretching direction of the diaphragm. The product is placed on the carrier plate 4 with the diaphragm, and the film absorbing plate 3 is flipped around the rotation center axis to the top of the carrier plate 4, so that the diaphragm on the film absorbing plate 3 covers the upper surface of the product, thereby forming a double-layer diaphragm structure covering the upper and lower surfaces of the product.

[0027] In this embodiment, the carrier plates 4 are arranged in two groups in parallel along the central axis of rotation, so that two groups of products can be wrapped with the membrane at the same time, and more groups can also be arranged accordingly.

[0028] Furthermore, a rotating shaft 7 is fixedly provided at the end of the film absorbing plate 3 , and the rotating shaft 7 is fixedly connected to an output end of a rotating motor 8 arranged at a side of the film absorbing plate 3 , and is driven to rotate by the rotating motor 8 .

[0029] Specifically, the bottom plate 1 is provided with a linear slide 9 along the diaphragm discharge direction on the side edge of the film suction plate 3, and the output end of the linear slide 9 is slidably connected to a film clamping bracket 10, and the film clamping block 6 is arranged side by side on the film clamping bracket 10, and is driven by the linear slide 9 to realize reciprocating movement along the discharge direction.

[0030] In this embodiment, there are four groups of film blocks 6 on the film clamping bracket 10, which are driven by pneumatic fingers arranged on the film clamping bracket 10 to clamp the diaphragm. Since the structure of the pneumatic fingers driving the film clamping blocks 6 to clamp is the existing technology, the structure and position of the pneumatic fingers are not set in the figure.

[0031] Furthermore, the bottom plate 1 is provided with a guide rail 11 extending along the film discharging direction on the other side of the film absorbing plate 3 away from the linear slide 9, and the two ends of the film clamping bracket 10 are respectively slidably connected to the linear slide 9 and the guide rail 11.

[0032] Furthermore, a plurality of groups of photoelectric sensors 12 are fixedly arranged on the side of the linear slide 9, and a sensing pole piece 13 for monitoring by the photoelectric sensor 12 is arranged at the moving end of the linear slide 9. When the film clamping bracket 10 moves, the sensing pole piece 13 passes through the sensing path of the photoelectric sensor 12, and determines whether the film clamping bracket 10 is in place according to the position where the photoelectric sensor 12 is arranged.

[0033] In addition, if Figure 3 As shown, a heat sealing head 14 is also provided on the side of the carrier plate 4, and the heat sealing head 14 moves along the discharge direction of the diaphragm to heat-seal the upper and lower layers of the product into one.

[0034] This embodiment includes two groups of carrier plates 4 , and the heat sealing heads 14 are in two groups, which are correspondingly arranged between the two groups of carrier plates 4 .

[0035] Furthermore, a cutter 15 moving along the discharge direction is provided between the two groups of heat sealing heads 14 , and the cutter 15 can split the membrane between the two groups of carrier plates 4 , thereby playing a role in separating the products.

[0036] Furthermore, the heat sealing head 14 and the cutter 15 are connected to the same transmission shaft 16, and the transmission shaft 16 is connected to the moving output end of a heat pressing linear mechanism through a heat pressing bracket 17, and is driven by the heat pressing linear mechanism to move along the discharge direction.

[0037] In this embodiment, the hot pressing linear mechanism is a rodless cylinder 18 .

[0038] The working process of this embodiment is as follows: the film-pulling jaws of the film-pulling mechanism clamp the diaphragm from the discharge port of the film-discharging mechanism 2 and move toward the film-absorbing plate 3, and the negative pressure gas source is activated, so that the diaphragm is adsorbed on the surface of the film-absorbing plate 3 and the carrier plate 4. The external jaws place the product on the carrier plate 4, the film-discharging mechanism 2 cuts off the starting end of the diaphragm, and at the same time, the flip mechanism drives the film-absorbing plate 3 to flip to the top of the carrier plate 4, and the product is wrapped between the upper and lower layers of the diaphragm. The cutting cylinder is activated, driving the cutting roller located between the two groups of carrier plates 4 to move, so that the upper and lower layers of the diaphragm are heat-sealed together on one side, and the diaphragm is cut from the middle of the two groups of carrier plates 4 on the other side, so that the two products are separated.
