[0033] Example

[0034] like Figure 1As shown, the present invention proposes a PE stretch film production equipment with automatic waste recycling function, including a base plate 1, and multiple sets of guide rollers 2 are rotatably arranged above the base plate 1. The multiple sets of guide rollers 2 are used to tension the PE stretch film. The tensioning mechanism composed of multiple sets of guide rollers 2 is the prior art and will not be described in detail here.

[0035] Furthermore, the aforementioned production equipment includes a winding mechanism 3 installed on the top of the base plate 1. The winding mechanism 3 is used to wind PE stretch film. The winding mechanism 3 includes two sets of side plates 31 fixedly connected to the top of the base plate 1. A rotating rod 32 is rotatably connected between the two sets of side plates 31. The rotating rod 32 rotates in its original position, and the rotating rod 32 is detachably connected to the side plates 31, making it easy to remove the rotating rod 32 and take off the rolled PE stretch film. A first servo motor 33 is installed on the side of one set of side plates 31 away from the rotating rod 32. The output end of the first servo motor 33 passes through the side plate 31 and is fixedly connected to the rotating rod 32. After the first servo motor 33 is started, it drives the rotating rod 32 to rotate, thereby realizing the rolling of PE stretch film. Multiple sets of rollers 34 are installed on the rotating rod 32. When the rotating rod 32 rotates, it drives the rollers 34 to rotate synchronously, thereby winding the PE stretch film onto the rollers 34, which facilitates the separation of the rollers 34.

[0036] For further details, please refer to Figure 2 The aforementioned production equipment also includes multiple sets of V-shaped blades 4 disposed above the base plate 1. The V-shaped blades 4 are used to cut the PE stretch film. The V-shape facilitates the cutting of the wider PE stretch film, and the gaps after cutting facilitate the winding of the PE stretch film onto multiple sets of rolls 34. The multiple sets of V-shaped blades 4 are fixedly connected to a mounting frame 41 on the side near the winding mechanism 3. The mounting frame 41 is U-shaped and fixedly connected to the top of the base plate 1. The fixed position of the mounting frame 41 thus fixes the position of the V-shaped blades 4.

[0037] Specifically, such as Figure 1As shown, the aforementioned production equipment includes a waste collection assembly 5 installed on the top of the base plate 1. The waste collection assembly 5 is used to collect the cut PE stretch film. The waste collection assembly 5 includes multiple sets of positioning wheels 51 installed on the side of the mounting frame 41 away from the V-shaped blade 4. The PE stretch film waste cut by the V-shaped blade 4 passes between adjacent sets of positioning wheels 51. The positioning wheels 51 guide the cut PE stretch film, preventing it from tilting and causing wrinkles. The waste collection assembly 5 also includes a positioning frame 52 installed on the top of the base plate 1. The positioning frame 52 is U-shaped, and two sets of collection wheels 53 are rotatably connected to the top of the positioning frame 52. The collection wheels 53 rotate in their original positions. The PE stretch film waste cut by the multiple sets of V-shaped blades 4 all pass between the two sets of collection wheels 53, which collect the multiple pieces of cut PE stretch film waste together. A first guide wheel 54 is provided at the top of the positioning frame 52, and a second guide wheel 55 is provided above the first guide wheel 54. The second guide wheel 55 is perpendicular to the first guide wheel 54. Both the first guide wheel 54 and the second guide wheel 55 are rotatably connected to the top of the positioning frame 52 through a positioning plate, so that the first guide wheel 54 and the second guide wheel 55 rotate in their original positions. Through the guiding action of the first guide wheel 54 and the second guide wheel 55, the PE stretch film waste, which was originally in the same direction as the PE stretch film, is made perpendicular to the PE stretch film's moving direction, facilitating the conveying of the PE stretch film waste to the side of the bottom plate 1. A third guide wheel 56 is provided on one side of the second guide wheel 55, located directly above the heating furnace 6. Through the guiding action of the third guide wheel 56, the PE stretch film waste is conveyed to the heating furnace 6 for melting and recycling.

[0038] For further details, please refer to Figure 1 , Figure 3 and Figure 4The aforementioned production equipment includes a traction mechanism 7, which is used to traction PE wrapping film waste. The traction mechanism 7 includes a vertical plate 71 fixedly connected to the top of the base plate 1, and a third guide wheel 56 rotatably connected to the side of the vertical plate 71, maintaining its original position. The traction mechanism 7 also includes a fixed frame 72 located below the third guide wheel 56. The fixed frame 72 is U-shaped and fixedly connected to the vertical plate 71, and its position is fixed. A second servo motor 73 is mounted on the outside of the fixed frame 72. The output end of the second servo motor 73 passes through the fixed frame 72 and is fixedly connected to a first extrusion roller 74. After starting, the second servo motor 73 drives the first extrusion roller 74 to rotate in its original position. A second extrusion roller 75 is disposed within the fixed frame 72. The shaft of the second extrusion roller 75 is slidably engaged with the fixed frame 72, allowing the second extrusion roller 75 to move closer to or further away from the first extrusion roller 74. The PE stretch film passes between the first extrusion roller 74 and the second extrusion roller 75. Rubber sleeves are installed on the outer rings of both rollers to increase friction and facilitate the movement of the PE stretch film waste. A U-shaped movable frame 76 is provided on the outer side of the second extrusion roller 75. The second extrusion roller 75 is rotatably connected to the movable frame 76. When the movable frame 76 moves, it drives the second extrusion roller 75 to slide within the fixed frame 72. Multiple sets of limiting rods 77 are fixedly connected to the side of the fixed frame 72 away from the upright plate 71. These limiting rods 77 all pass through the movable frame 76 and slide within it. The fixed position of the limiting rods 77 ensures smooth movement of the movable frame 76. The end of the limiting rod 77 away from the fixed frame 72 is fixedly connected to the limiting plate 78. Multiple sets of springs 79 are provided between the moving frame 76 and the limiting plate 78. The multiple sets of springs 79 are respectively sleeved and installed on the outer ring of the multiple sets of limiting rods 77. Through the elastic force of the springs 79, the moving frame 76 is brought closer to the fixed frame 72, so that the second extrusion roller 75 is brought closer to the first extrusion roller 74 to extrude the PE wrapping film, increase the friction, and ensure stable traction.

[0039] Furthermore, the aforementioned production equipment also includes a heating furnace 6, which is used to melt PE stretch film waste. At the same time, the heating furnace 6 has a discharge port for discharging the processed PE stretch film waste, which is convenient for recycling.

[0040] Finally, the aforementioned production equipment includes a cutting assembly 8 positioned above the feed inlet of the heating furnace 6. The cutting assembly 8 is used for quantitative cutting of the PE stretch film. The cutting assembly 8 includes a support frame 81 positioned below the fixed frame 72. The support frame 81 is U-shaped and its position is fixed. Mounting plates 82 are fixedly connected to both sides of the support frame 81, and a cylinder 83 is installed between the two sets of mounting plates 82. The position of the cylinder 83 is fixed. A cutting blade 84 is fixedly connected to the output end of the cylinder 83. The PE stretch film passes between the support frame 81 and the cutting blade 84. After the cylinder 83 is activated, it drives the cutting blade 84 to approach the support frame 81 to cut the PE stretch film waste, causing it to fall into the feed inlet of the heating furnace 6 and slide into the heating furnace 6.

[0041] In this embodiment, after the first servo motor 33 starts, it drives the rotating rod 32 to rotate, thereby causing the roll 34 to rotate synchronously and wind the PE stretch film onto the roll 34. Simultaneously, during the movement of the PE stretch film, the V-shaped blade 4 cuts the PE stretch film, facilitating control of the width of the PE stretch film wound on the roll 34. The waste material cut off by the V-shaped blade 4 passes through the positioning wheel 51 and is concentrated between the two sets of concentrating wheels 53. Guided by the first guide wheel 54, the second guide wheel 55, and the third guide wheel 56, it passes between the first extrusion roller 74 and the second extrusion roller 75. The spring 79 releases its elastic force, causing the moving frame 76 to approach the fixed frame 72, thereby driving the second extrusion roller 75 to approach the first extrusion roller 74 to extrude the PE stretch film waste. Thus, after the second servo motor 73 starts, it drives the first extrusion roller 74 to rotate, thereby traction of the PE stretch film waste and conveying it to the heating furnace 6 below. At the same time, the cylinder 83 intermittently extends and retracts, and the PE stretch film waste passes between the support frame 81 and the cutting blade 84. The intermittent extension and retraction of the cylinder 83 cuts the PE stretch film waste, causing it to fall into the heating furnace 6 for recycling.

[0042] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
