[0002] Stone adhesive has good physical and mechanical properties, durability, construction performance, and adhesion. It can be used to paste stone to greatly improve construction quality and efficiency. Common adhesives include marble adhesives, tile adhesives, and artificial stone adhesives. After the stone adhesive is produced, a film wrapping machine will be used to wrap a film around the outside of its packaging, which can achieve good dust-proof, moisture-proof, scratch-proof and product protection.

[0003] For example, a Chinese patent (publication number: CN220536019U) discloses a film wrapping packaging machine, including a machine base, a film fixing structure is provided on the front of the upper end face of the machine base, a rotating wrapping structure passes through the center of the lower end face, and a packaging fixing structure is half-surrounded on the upper side of the rotating wrapping structure. The threaded rod is driven to rotate by manually rotating the rotating rod so that the fixed plate and the rotating seat fix the goods, which can better control the force of fixing the goods, thereby avoiding damage to the goods. The limit holes and the card blocks can be used in conjunction with the threaded rod to adjust the distance between the fixed plate and the rotating seat, which can make it more convenient to package different goods and increase the scope of application.

Therefore, a film wrapping machine is proposed to solve the above problems. Utility Model Content

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] 1. When using the film wrapping machine, the package is placed on the base, and then the upper and lower sides of the package are clamped by two circular plates provided by the wrapping mechanism to prevent the package from moving at will.

When in use, the package is placed on the top surface of the bottom circular plate 706, and then the screw rod 712 is rotated, and the screw rod 712 drives the rectangular plate 710 to slide downward in cooperation with the guide rod 711. Further, the rectangular plate 710 pushes the rotating rod 705 to slide downward inside the transmission cylinder 704, thereby causing the circular plate at the bottom of the rotating rod 705 to rotate. 706 abuts against the top of the package, cooperates with the bottom circular plate 706 to clamp the package, and then pulls the film to the outer peripheral wall of the package and fixes it. The winding mechanism includes a motor 701 fixed to the top surface of the top bin 3, and a transmission rod 702 is fixed to the bottom end of the output shaft of the motor 701. Two driving wheels 707 are fixed on the outer peripheral wall of the transmission rod 702.

The truncated cone block 806 pushes the extrusion block 805 to move toward the sleeve 5 to increase the extrusion force, or the truncated cone block 806 attracts the extrusion block 805 to move away from the sleeve 5 to reduce the extrusion force, thereby achieving the effect of changing the rotational damping of the sleeve 5 on the outer peripheral wall of the vertical rod 4, avoiding the inconvenience caused by the sleeve 5 still rotating due to inertia when the winding mechanism stops and releasing the film.

[0027] A gripper is fixed to the top of the screw rod 801, and a sliding hole is provided on the outer peripheral wall of the vertical rod 4 for the extrusion block 805 to penetrate and be slidably connected thereto.

[0028] The working principle of the above embodiment is:

[0029] (1) When in use, the package is placed on the top surface of the bottom circular plate 706, and then the screw rod 712 is rotated. The screw rod 712 drives the rectangular plate 710 to cooperate with the guide rod 711 to slide downward. The rectangular plate 710 pushes the rotating rod 705 to slide downward inside the transmission cylinder 704, so that the circular plate 706 at the bottom end of the rotating rod 705 abuts against the top of the package, and cooperates with the bottom circular plate 706 to clamp the package, further pulling the film to the outer peripheral wall of the package and fixing it, and then starting the motor 701. The motor 701 drives the transmission rod 702 to rotate, and the transmission rod 702 drives the two driving wheels 707 to rotate. The two driving wheels 707 drive the two transmission wheels 708 to rotate synchronously in the same direction through the two belts 709. The two transmission wheels 708 then drive the transmission cylinder 704 and the rotating column 703 to rotate synchronously in the same direction. The transmission cylinder 704 drives the rotating rod 705 to rotate, so that the two circular plates 706 drive the package to rotate and wrap the film.

[0030] (2) When it is necessary to adjust the rotational damping of the sleeve 5 and the film cylinder 6, the screw 801 is rotated, and the screw 801 drives the truncated cone block 806 to move up and down. The truncated cone block 806 pushes the extrusion block 805 to move toward the sleeve 5 to increase the extrusion force, or the truncated cone block 806 attracts the extrusion block 805 to move away from the sleeve 5 to reduce the extrusion force, thereby achieving the effect of changing the rotational damping of the sleeve 5 on the outer peripheral wall of the vertical rod 4, avoiding the inconvenience caused by the sleeve 5 still rotating due to inertia when the winding mechanism stops.
