[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-4A blown film equipment suitable for biodegradable plastics includes a base 1. The base 1 is characterized by the following features: a blown film equipment body 5 is fixedly mounted on the base 1; four support legs 4 are fixedly mounted at the bottom of the base 1; the bottom ends of all four support legs 4 are open; and the four support legs 4 are square boxes. The support legs 4 are used to support the base 1. A stabilizing mechanism is installed inside each support leg 4 to stabilize it when it is suspended, thereby improving the stability of the blown film equipment. A moving mechanism is installed at the bottom of the base 1 to facilitate the movement of the blown film equipment, thus improving its usability.

[0023] In detail, the moving mechanism includes a first lead screw 34, which is rotatably connected to the bottom end of the base 1 via a bearing. The first lead screw 34 is configured to drive the receiving plate 32 to move vertically along the surface of the slide bar 31. A first toothed ring 36 is fixedly installed on the first lead screw 34, which is configured to mesh with the first gear 35.

[0024] Furthermore, a motor 37 is fixedly installed on the base 1. The motor 37 has forward and reverse rotation functions. The motor 37 is configured to drive the first gear 35 to rotate. The first gear 35 is fixedly installed on the shaft end of the motor 37. The first gear 35 meshes with the first gear ring 36. By setting the first gear 35 and the first gear ring 36, the motor 37 drives the first lead screw 34 to rotate when it is working.

[0025] Furthermore, the first lead screw 34 is threadedly connected to a receiving plate 32. The receiving plate 32 is used to support the installation of the casters 33. The receiving plate 32 is square in shape, and four casters 33 are fixedly installed at the bottom of the receiving plate 32. The casters 33 are used for the movement of the blown film equipment.

[0026] More specifically, two slide rods 31 are fixedly installed at the bottom of the base 1. The two slide rods 31 are symmetrically arranged with the first lead screw 34 as the center. The receiving plate 32 slides on the slide rods 31. The arrangement of the slide rods 31 serves to limit the movement of the receiving plate 32 when the first lead screw 34 drives the receiving plate 32 to move, which facilitates the vertical movement of the receiving plate 32. When it is necessary to move the blown film equipment body 5, the motor 37 is started. The motor 37 drives the first gear 35 to rotate. The first gear 35 meshes with the first gear ring 36, which will drive the first lead screw 34 to rotate. When the first lead screw 34 rotates, it will drive the receiving plate 32 to move vertically upward along the surface of the slide rod 31 until the universal wheel 33 at the bottom of the receiving plate 32 contacts the ground and supports the support leg box 4. At this time, the blown film equipment body 5 can be moved.

[0027] In general, the stabilizing mechanism includes a second lead screw 22, which is rotatably connected to the leg box 4 via a bearing. The second lead screw 22 is used to drive the support leg 21 to move vertically along the inner wall of the leg box 4. The support leg 21 is threaded onto the second lead screw 22. The support leg 21 is a square rod and slides on the inner wall of the leg box 4. The support leg 21 serves to support the base 1 when the leg box 4 is suspended.

[0028] Finally, a second toothed ring 23 is fixedly installed on the lead screw 22. The second toothed ring 23 is designed to mesh with the second gear 25. A shaft 24 is rotatably connected to the support leg box 4. One end of the shaft 24 passes through the inner wall of the support leg box 4. The shaft 24 is designed to support the installation of the second gear 25. The second gear 25 is fixedly installed on one end of the shaft 24. The second gear 25 meshes with the second toothed ring 23. By setting the second gear 25 and the second toothed ring 23, when the shaft 24 rotates, it drives the second lead screw 22 to rotate, which facilitates the second lead screw 22 to drive the support leg 21 to move.

[0029] Working method: When it is necessary to move the blown film equipment body 5, start the motor 37. The motor 37 drives the first gear 35 to rotate. The first gear 35 meshes with the first gear ring 36, which will drive the first lead screw 34 to rotate. When the first lead screw 34 rotates, it will drive the receiving plate 32 to move vertically upward along the surface of the slide rod 31 until the universal wheel 33 at the bottom of the receiving plate 32 contacts the ground and supports the support leg box 4. At this time, the blown film equipment body 5 can be moved.

[0030] Once the blown film equipment body 5 has moved to the appropriate position, the universal wheel 33 is lifted by the reverse rotation of the motor 37 until the support leg box 4 supports the base 1. If a support leg box 4 is suspended in the air, the shaft 24 in the suspended position can be rotated. The shaft 24 drives the second gear 25 to rotate. The second gear 25 meshes with the second gear ring 23, which will drive the second lead screw 22 to rotate. When the second lead screw 22 rotates, it will drive the support leg 21 to move vertically along the inner wall of the support leg box 4 until the support leg box 21 contacts the ground. At this time, the stability of the blown film equipment body 5 can be maintained.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
