AI Technical Summary
When the vertical centerline of the workpiece deviates from the centerline of the film wrapping path in existing film wrapping machines, the unfolding path of the film and the wrapping path of the workpiece will deviate, resulting in uneven sealing effect of the film.
The system employs a pneumatic jacking structure, Y-axis and Z-axis linear screw modules, and an adjustable-distance wrapping mechanism. The pneumatic jacking structure presses against and limits the workpiece, the Y-axis linear screw module controls the workpiece position, and the Z-axis linear screw module drives the adjustable-distance wrapping mechanism to precisely wrap the workpiece, ensuring that the vertical centerline of the workpiece is aligned with the centerline of the wrapping film.
It significantly reduces deviations during the workpiece wrapping process, ensures uniform wrapping of the film material, avoids excessively tight or loose film in some areas, and improves packaging accuracy and efficiency.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0019] Example 1, by Figures 1 to 4 The present invention includes a vertical frame 1 and a horizontal frame 2 fixed at one end of its surface. A support platform 3 is slidably installed on the top of the horizontal frame 2, and a tray 5 is installed on the top of the support platform 3. A Y-axis lead screw linear module 4 is provided inside the horizontal frame 2 for driving the tray 5 closer to or away from the vertical frame 1. A pneumatic push structure 6 for pressing the workpiece against the tray 5 is installed on the outer wall of the support platform 3 away from the vertical frame 1. A frame 9 is slidably installed on the outer wall of the vertical frame 1 close to the horizontal frame 2, and an adjustable-distance wrapping mechanism 10 is installed at the bottom of the frame 9. A Z-axis lead screw linear module 7 is provided inside the vertical frame 1 for driving the frame 9 and the adjustable-distance wrapping mechanism 10 to perform vertical lifting. A PLC control panel 8 is installed on one outer wall of the vertical frame 1 and is electrically connected to the input end of the Y-axis lead screw linear module 4, the pneumatic push structure 6, the Z-axis lead screw linear module 7, and the adjustable-distance wrapping mechanism 10.
[0020] Example 2, based on Example 1, is... Figure 4 , Figure 5 and Figure 6 Provided is an integrally formed support part 501 at one edge of the top of the tray 5;
[0021] The pneumatic jacking structure 6 includes a hollow recessed frame 601 fixed to one outer wall of the support platform 3, a cylinder 602 hinged to one inner wall of the hollow recessed frame 601, and a support column 603 fixed at one end inside the hollow recessed frame 601. A U-shaped arm 604 is fitted onto one end of the surface of the support column 603. One outer wall of the U-shaped arm 604 is hinged to the top of the piston rod of the cylinder 602. The interior of the U-shaped arm 604 has a notch that mates with the tray 5. The U-shaped arm 604 is made of stainless steel. When the workpiece to be wrapped is placed on top of the tray 5, the operator uses the PLC control panel 8 to activate the cylinder 602 in the pneumatic pushing structure 6. That is, the piston rod of the cylinder 602 actively retracts, and the cylinder 602 drives the U-shaped arm 604 to rotate around the support column 603 through the piston rod, so that the U-shaped arm 604 gradually approaches the support part 501, and the U-shaped arm 604 and the support part 501 are used to fix the workpiece and prevent the workpiece from shifting position during the subsequent wrapping process.
[0022] The distance-adjustable film wrapping mechanism 10 comprises a motor 1001 installed at the top end of the rack 9, a main shaft 1002 installed at the output end of the motor 1001, and a support arm 1003 fixed at the bottom end of the support arm 1003. One side of the top end of the support arm 1003 is fixed with a shaft seat 1004, the inside of the shaft seat 1004 is installed with a threaded shaft 1005, one end of the threaded shaft 1005 away from the main shaft 1002 is provided with a lug plate 1006, the bottom end of the lug plate 1006 is fixed with a film winding drum 1007, one end of the threaded shaft 1005 extends into the inside of the lug plate 1006 and is rotationally connected with the lug plate 1006, and the inside of the shaft seat 1004 is installed with guide rods on both sides. One end of the guide rod penetrates to the outside of the shaft seat 1004 and is fixedly connected with one side of the outer wall of the lug plate 1006;
[0023] After the workpiece is fixed and the Y-axis position is adjusted, the worker manually rotates the threaded shaft 1005 to drive the lug plate 1006 and the film winding drum 1007 to approach or move away from the workpiece until the packaging film on the film winding drum 1007 is attached to the workpiece. At this time, the worker manually rotates the support arm 1003 to make the packaging film wrap several turns on the workpiece to facilitate subsequent film wrapping operation.
[0024] Rotating the main shaft 1002 by the motor 1001 drives the support arm 1003 and the film winding drum 1007 to rotate around the main shaft 1002, that is, the packaging film on the film winding drum 1007 is continuously wrapped on the workpiece, and the Z-axis screw linear module 7 synchronously drives the distance-adjustable film wrapping mechanism 10 to move in the Z-axis direction, so that the whole workpiece is wrapped by the film, which promotes the combination between the film and the workpiece to be firm, and the film completely wraps the workpiece.
[0025] In use, the workpiece to be wrapped is first placed accurately on the tray 5, and once the workpiece is placed, the pneumatic push structure 6 is activated, at which time the pneumatic push structure 6 pushes the workpiece against the support portion 501 of the tray 5 to prevent the workpiece from shifting position during the subsequent wrapping process. At the same time, the pneumatic push structure 6 and the support portion 501 limit the workpiece, ensuring that the workpiece is always in a fixed state during the entire wrapping process. After the workpiece is tightly positioned, the worker turns on the Y-axis lead screw linear module 4 through the PLC control panel 8, and the Y-axis lead screw linear module 4 controls the movement of the workpiece, the support table 3, and the tray 5 in the Y-axis direction, ensuring that the workpiece is aligned with the wrapping central axis of the adjustable wrapping mechanism 10, so that the vertical central axis of the workpiece is substantially consistent with the wrapping central axis of the adjustable wrapping mechanism 10. After the positioning of the workpiece is accurately confirmed, the worker manually adjusts the adjustable wrapping mechanism 10 so that the packaging film is attached to the outer wall of the workpiece. Subsequently, the worker turns on the Z-axis lead screw linear module 7 and the adjustable wrapping mechanism 10 through the PLC control panel 8, and the adjustable wrapping mechanism 10 wraps the packaging film around the workpiece, while the Z-axis lead screw linear module 7 controls the Z-axis position of the adjustable wrapping mechanism 10, so that the adjustable wrapping mechanism 10 wraps from top to bottom, ensuring that the film material is tightly and uniformly attached to the surface of the workpiece. Once the wrapping operation is complete, the packaging film is cut using a cutter, and the final packaged workpiece is simply inspected to ensure that the film completely wraps the workpiece and that the seal is secure.
