AI Technical Summary
Existing residual film recycling machines suffer from systemic technical defects in their baling devices during the recycling process, resulting in low baling efficiency, high maintenance costs, large amounts of impurities carried over, and a high risk of secondary pollution.
The system uses multiple sets of modular narrow sub-belts to replace the traditional wide packing belts, combined with limit blocks and support rollers, to achieve automatic deviation correction and impurity removal, reducing maintenance costs and improving operational efficiency.
This technology enables efficient packaging of residual film, reduces the amount of impurities carried over, decreases maintenance time and costs, and improves the operating efficiency and economy of the residual film recycling machine.

Abstract
Claims
1. A multi-strand residual film packaging device, comprising a frame (10), an upper strapping assembly (20), and a lower strapping assembly (30), wherein the upper strapping assembly (20) and the lower strapping assembly (30) are both mounted on the frame (10) and form a residual film winding space between them, characterized in that: The upper strapping assembly (20) and the lower strapping assembly (30) each include multiple sets of strapping sub-strips (40), an active roller (50) and a driven roller (60). The multiple sets of strapping sub-strips are arranged side by side. The active roller (50) and the driven roller (60) pass through the front and rear ends of the multiple sets of strapping sub-strips respectively, thereby supporting and tensioning the multiple sets of strapping sub-strips.
2. The multi-belt devolatilizing and contaminant-removing type residual film packaging apparatus according to claim 1, characterized by: The packing sub-strip consists only of a drive belt (100), the front and rear ends of which are directly wound around the drive roller (50) and the driven roller (60), respectively; or, the packing sub-strip consists of a drive belt (100) and a bushing (101), the bushing (101) being disposed at the front and rear ends of the drive belt (100), and the drive belt (100) being sleeved on the drive roller (50) and the driven roller (60) respectively through the bushing (101).
3. The multi-belt devolatilizing and contaminant-removing type residual film packaging apparatus according to claim 2, characterized by: The driving roller (50) and the driven roller (60) are provided with a limiting block (90) at the corresponding positions. The limiting block (90) can generate a gap for leakage between two adjacent packing sub-strips and can stabilize the lateral offset of the packing sub-strips.
4. The multi-belt devolatilizing and linting apparatus for packaging of scrap film according to claim 3, wherein: When the packing sub-strip only contains the drive belt (100), the limiting block (90) is a circular ring structure, which is sleeved on the drive roller (50) and the driven roller (60); when the packing sub-strip includes the drive belt (100) and the bushing (101), the limiting block (90) is disposed on one side of the bushing (101), and the limiting block (90) is a circular ring structure or a semi-circular ring structure.
5. The multi-belt devolatilizing and linting apparatus for packaging of scrap film according to claim 3, wherein: At least the outer circumference of the limiting block (90) of the lower packing strap assembly (30) is provided with teeth.
6. The multi-belt devolatilizing and linting apparatus for packaging of scrap film of claim 1 wherein: The upper strapping assembly (20) and the lower strapping assembly (30) further include a support roller (70) and a side plate (103). The support roller (70) is arranged laterally within the multiple sets of strapping sub-strips and its two ends are mounted on the side plate (103) by bearings. The side plate (103) is arranged on both sides of the multiple sets of strapping sub-strips.
7. The multi-belt devolatilizing and linting apparatus of claim 1, wherein: The upper packing strap assembly (20) is obliquely disposed behind the frame (10). The drive shaft of the upper packing strap assembly (20) is located above the lower packing strap and is hinged to the frame (10). A demolding push rod (80) is provided between the frame (10) and the upper packing strap assembly (20). One end of the demolding push rod (80) is hinged to the upper packing strap assembly (20), and the other end is hinged to the frame (10).
8. The multi-belt devolatilizing and linting system of claim 1, wherein: A pressure sensor is provided, which is connected to the frame (10) via a mounting base.
9. The multi-belt devolatilizing and linting system of claim 1, wherein: The two sets of drive rollers (50) corresponding to the upper strapping assembly (20) and the lower strapping assembly (30) are synchronously driven by the transmission chain (102).
10. A residual film recycling machine, including a traction frame, characterized in that, The traction frame is equipped with a multi-belt impurity removal residual film packaging device as described in any one of claims 1-9.
