[0035] The film rolling structure includes a film rolling rod 21, and the rotating bracket 14 is equipped with a moving structure for driving the film rolling rod to move along the rotating bracket and a rotating structure for driving the film rolling rod to rotate. The film rolling rod is equipped with a film stripping structure, a film cutting structure and a film absorbing structure.

[0036] In this way, after the pallet conveyor line conveys the material box pallet to the film removal station, the pressing cylinder of the pressing structure extends out, so that the pressing plate tightly presses the upper end surface of the material box pallet, and then the moving structure drives the film rolling rod to move near the pallet packaging film, and the rotating structure drives the film rolling rod to rotate, so that the film cutting structure is facing the pallet packaging film, and the film cutting structure cuts the pallet packaging film, and then the film cutting structure is reset, and the rotating structure drives the film rolling rod to rotate, so that the film suction structure is facing the pallet packaging film, and the moving structure drives the film rolling rod to move, so that the film suction structure adsorbs one end of the packaging film, and then the frequency conversion motor drives the rotating bracket to rotate, and cooperates with the moving structure to realize the position adjustment of the film rolling rod, and the rotating structure drives the film rolling rod to rotate, and the pallet packaging film is wound on the film rolling rod. After the winding is completed, the film withdrawal structure withdraws the pallet packaging film on the film rolling rod downward to complete the film removal operation. The whole process is automated.

[0037] The clamping cylinder extends to make the clamping plate press against the upper end surface of the material box tray. At this time, the cylinder mounting plate and the bearing seat can no longer rotate. The clamping connecting shaft can also rotate relatively with the rotating bracket due to the bearing pair installed inside the bearing seat.

[0038] During implementation, the mobile structure includes a film roll support 22, and linear guide rails 23 are fixedly installed on both sides of the rotating support 14. Slide blocks 24 are slidably matched on the linear guide rails 23, and the film roll support 22 is fixedly connected to the slide blocks;

[0039] A horizontal servo motor 25 is fixedly mounted on the film roll support, a gear 26 is fixedly mounted on the output shaft of the horizontal servo motor, a rack seat 27 is fixedly mounted downwardly on the rotating support 14, and a rack 28 meshing with the gear is fixedly mounted at the lower end of the rack seat 27;

[0040] The rotating structure is installed on the film rolling bracket and is used to drive the film rolling rod to rotate.

[0041] In this way, the horizontal servo motor drives the gear to rotate, and the gear engages with the rack. Since the rack seat is fixedly installed on the rotating bracket, when the horizontal servo motor rotates, it drives the film roll bracket to move.

The upper and lower ends of the rodless cylinder are fixedly connected to the film rolling rod through a fixing plate 33. A film stripping rod 35 is fixed on the movable seat 34 of the rodless cylinder. The film rolling rod is provided with a waist-shaped through hole 36, and the outer end of the film stripping rod extends outward through the waist-shaped through hole. In this way, the movable seat of the rodless cylinder drives the film stripping rod to move, and the film stripping rod strips the tray packaging film wound on the film rolling rod. The setting of the waist-shaped through hole facilitates the movement of the film stripping rod.

[0046] During implementation, two film stripping rods are provided and arranged on two opposite sides of the movable seat 34, and the waist-shaped through hole is arranged opposite to the stripping rod, so as to better strip the tray packaging film on the film rolling rod.

[0047] During implementation, the film cutting structure includes a film cutting blade 37, an electromagnet 38 is fixedly mounted on the movable seat of the rodless cylinder, and the blade seat of the film cutting blade 37 can be attracted by the electromagnet; the film rolling rod is provided with a clearance slot 39 facing the film cutting blade. The movable seat of the rodless cylinder drives the electromagnet to move, and the electromagnet drives the film cutting blade to move, and the film cutting blade cuts the pallet packaging film.

[0048] During implementation, it also includes a blade clamping air claw 4, which is fixedly mounted on a fixed plate at the upper end of the film rolling rod, and is used to clamp the blade seat of the film cutting blade. The film cutting blade is clamped by the blade clamping air claw, and when the film is removed, the film cutting blade can be fixed by the blade clamping air claw without following the movement of the electromagnet. After the film removal rod is reset, the electromagnet is energized to adsorb the film cutting blade.

[0049] During implementation, the film suction structure includes a plurality of sponge suction cups 42 fixedly mounted on the film rolling rod, the sponge suction cups are distributed along the axis of the film rolling rod, and the film rolling rod is provided with air passage holes facing the sponge suction cups.

The rotating bearing pair mainly includes two tapered roller bearings and a thrust ball bearing, which mainly provide rotating support for the nested transmission shaft.

[0051] During implementation, the lower end of the rotary drive shaft is connected to the film rolling rod through four locking pins 44 arranged in a cross shape.

[0052] Specifically, the frame is divided into two layers, the lower layer is 4 columns, and the upper layer is a gantry structure frame. The upper and lower layers are connected by screws and span above the pallet conveyor line, which can not only provide an installation support platform for the film removal machine, but also save space, while not affecting the normal conveying process of the material box pallet.

[0053] The rotary drive mechanism is installed on the upper frame of the rack. The variable frequency motor is installed on the upper end surface of the frame, and the bearing support is installed on the lower end surface of the frame. Specifically, the horizontal servo motor is connected to a reducer, and the vertical servo motor is connected to a right-angle reducer. The lower end of the film roll bracket is fixedly connected to the rotary support by screws.

[0054] Specifically, it also includes a PLC controller for controlling the actions of the electrical components therein.

[0055] principle:

[0056] After the pallet conveyor line transports the material box pallet to the film removal station, the clamping cylinder extends out to make the clamping plate tightly press the upper end surface of the material box pallet, and then the horizontal servo motor starts to move the film rolling rod of the film rolling structure to the vicinity of the pallet packaging film, and the vertical servo motor starts to make one side of the film cutting blade on the film rolling rod face the pallet packaging film, and then the electromagnet on the rodless cylinder is energized, the blade clamping claw opens, and the film cutting blade is adsorbed on the moving seat of the rodless cylinder. At this time, the rodless cylinder is ventilated, and the moving seat of the rodless cylinder drives the film cutting blade to move downward and cut the pallet packaging film. After the film cutting is completed, the rodless cylinder returns to its initial position, the blade clamping claw closes, and the electromagnet is powered off. Then the vertical servo motor is started to make one side of the sponge suction cup on the film rolling rod face the pallet packaging film. For the pallet packaging film, the vacuum system is started, and the sponge suction cup absorbs the cut packaging film under negative pressure. Then the vertical servo motor is started, so that the film rolling rod begins to rotate and wind the packaging film. At the same time, the horizontal servo motor is also started, so that the film rolling rod revolves around the material box pallet to wind a circle of packaging film around the outer periphery of the material box pallet. After the film rolling rod completes a 360° packaging film winding, the horizontal servo motor is started to move the film rolling rod away from the material box pallet to just above the packaging film collection box. The vacuum system is turned off, the sponge suction cup no longer absorbs the packaging film, and the rodless cylinder is ventilated. The moving seat of the rodless cylinder drives the film retracting rod to move downward, and drives the packaging film off the film rolling rod and drops it into the packaging film collection box. After the film is removed from the material box pallet, it flows to the next station.

[0057] Finally, it should be noted that those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include these modifications and variations.
