Description

Technical Field

[0001] This utility model belongs to the field of scrap recycling technology, specifically relating to a device for recycling scraps from blown film packaging bags. Background Technology

[0002] The blown film process significantly improves packaging efficiency through continuous automated processes such as forming, filling, and sealing. Packaging bags produced by blown film technology have excellent comprehensive performance in terms of product packaging, storage, transportation, moisture protection, and appearance. During the blown film process, scraps are generated. Recycling these scraps can reduce the accumulation of plastic waste and reduce environmental pollution caused by landfill and incineration.

[0003] For example, in the Chinese utility model with announcement number CN221161161U and name "A Plastic Packaging Bag Scrap Recycling Pack," although a base plate is set up to support and fix the top components, a placement groove is used to place the collecting mechanism, which is used to store the recycled scraps, and a hydraulic cylinder is used to drive the pressing block to move. When the pressing block moves, it can automatically press the scraps inside the collecting mechanism, which can save manpower. However, the scraps are not softened before compression, and the gaps between the scraps are large during compression, which will occupy a large space after compression. Utility Model Content

[0004] The purpose of this utility model is to provide a packaging bag blown film scrap recycling device with a simple structure and reasonable design in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A packaging bag blown film scrap recycling device includes a box body, a compression cylinder is provided inside the box body, a heating pipe is provided outside the compression cylinder, a compression structure is provided above the heating pipe, a conveying pipe that penetrates the box body is fixedly connected to the side wall of the compression cylinder, a fan is installed at one end of the conveying pipe, and a feed pipe is fixedly connected to one side of the conveying pipe, and the position of the feed pipe is fixed by the conveying pipe.

[0007] As a further optimization of this utility model, a door is installed on one side of the box body, and a handle is fixedly connected to one side of the door, thereby fixing the position of the handle through the door.

[0008] As a further optimization of this utility model, a support rod is fixedly connected to the upper surface of the box, and a support plate is fixedly connected to the side of the support rod, thereby fixing the position of the support plate by the support rod.

[0009] As a further optimization of this utility model, a hydraulic cylinder is fixedly connected to one side of the support plate, and the compression structure includes a connecting plate fixedly connected to the output end of the hydraulic cylinder. A connecting rod is fixedly connected to the bottom end of the connecting plate, and a pressure block is fixedly connected to the bottom end of the connecting rod. The position of the pressure block is fixed by the connecting rod.

[0010] As a further optimization of this utility model, the upper surface of the pressure block is provided with a number of vent holes, and the pressure block is used to position the vent holes.

[0011] As a further optimization of this utility model, a pressing port is provided on the upper surface of the box, a through hole is provided at the bottom end of the compression cylinder, and a sliding plate is slidably connected inside the compression cylinder, so as to position the pressing port through the box.

[0012] The beneficial effects of this utility model are as follows: This utility model heats the scrap material inside the compression cylinder through a heating tube, thereby reducing the overall hardness of the scrap material. The hydraulic cylinder drives the connecting plate, connecting rod, and pressure block to move in position. The pressure block compresses the softened scrap material inside the compression cylinder, making the scrap material easier to compress and shape, and less likely to fall apart, which facilitates the subsequent transportation of the scrap material.

[0018] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example 1

[0020] like Figure 2 and Figure 3 As shown, a packaging bag blown film scrap recycling device includes a housing 1, inside which a compression cylinder 4 is installed. The housing 1 supports the compression cylinder 4, which stores the scrap. A conveying pipe 6, penetrating the housing 1, is fixedly connected to the side wall of the compression cylinder 4. The compression cylinder 4 supports and positions the conveying pipe 6. A blower 7 is installed at one end of the conveying pipe 6, which supports and positions the blower 7. The blower 7 facilitates the suction of the scrap into an inlet pipe 8. An inlet pipe 8 is fixedly connected to one side of the conveying pipe 6, which supports and positions the conveying pipe 6. The conveying pipe 6 facilitates the transport of the scrap to the compression cylinder 4. Inside the compression cylinder 4, a heating tube 5 is installed on the outside. The heating tube 5 is supported by the compression cylinder 4. The heating tube 5 is spirally wound around the outside of the compression cylinder 4. The heating tube 5 heats the scrap material inside the compression cylinder 4, softening the scrap material to facilitate subsequent compression molding and reducing dust pollution caused by mechanical stress. A door 2 is installed on one side of the box body 1. The door 2 is supported by the box body 1. The door 2 can protect the components inside the box body 1 and reduce the dissipation of heat inside the box body 1. A handle 3 is fixedly connected to one side of the door 2. The position of the handle 3 is fixed by the door 2, and the handle 3 facilitates the movement of the door 2.

[0021] like Figure 1 , Figure 2 and Figure 4 As shown, a support rod 9 is fixedly connected to the upper surface of the housing 1, supporting the support rod 9 via the housing 1. A support plate 10 is fixedly connected to the side of the support rod 9, supporting the support plate 10 via the support rod 9. A hydraulic cylinder 11 is fixedly connected to one side of the support plate 10, supporting the hydraulic cylinder 11 via the support plate 10. A connecting plate 12 is fixedly connected to the output end of the hydraulic cylinder 11, supporting the connecting plate 12 via the hydraulic cylinder 11. The hydraulic cylinder 11 can change the position between the connecting plate 12 and the compression cylinder 4. A connecting rod 13 is fixedly connected to the bottom end of the connecting plate 12, fixing the position of the connecting rod 13 via the connecting plate 12. The bottom end of the connecting rod 13 is fixedly connected to... A pressure block 14 is connected, and the position of the pressure block 14 is fixed by the connecting rod 13. The pressure block 14 compresses the scrap material. Several vent holes 15 are opened on the upper surface of the pressure block 14 to prevent pressure accumulation that could cause surface bulging or deformation. A through hole 17 is opened at the bottom of the compression cylinder 4. A sliding plate 18 is slidably connected inside the compression cylinder 4. After compression, the sliding plate 18 is moved by the cooperation of the through hole 17 and other components such as the rod, so that the staff can easily pick up the compressed scrap material on the sliding plate 18. A pressing port 16 is opened on the upper surface of the box body 1. The pressing port 16 is positioned by the box body 1 to facilitate the pressure block 14 to enter the compression cylinder 4 for pressing operation.

[0022] It should be noted that, in use, this packaging bag blown film scrap recycling device pushes the pressure block 14 to the top of the compression cylinder 4 via the hydraulic cylinder 11 to prevent the scrap from flying out of the pressing port 16. Then, the exhaust fan 7 is turned on to extract the scrap through the feed pipe 8 and convey it to the inside of the compression cylinder 4 via the conveying pipe 6. The heating pipe 5 heats the compression cylinder 4 to soften the scrap inside. The hydraulic cylinder 11 pushes the connecting plate 12, connecting rod 13 and pressure block 14 into the inside of the compression cylinder 4 through the pressing port 16 to press the scrap inside the compression cylinder 4. During pressing, the vent hole 15 prevents the scrap from being damaged due to thermal expansion and contraction caused by sudden temperature changes. After pressing is completed, the sliding plate 18 is moved by the cooperation of other components and the through hole 17. If it is necessary to clean the compression cylinder 4, the box door 2 can be opened and the compression cylinder 4 can be taken out.

[0023] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
