Description

Technical Field

[0001] This utility model belongs to the field of long filament geotextile production technology, and specifically relates to a multi-group linkage tube pulling mechanism. Background Technology

[0002] Long-filament geotextile is a polyester long-filament needle-punched nonwoven geotextile that contains no chemical additives and undergoes no heat treatment, making it an environmentally friendly building material. The production equipment for long-filament geotextile uses a center-shaft winding machine, which offers advantages such as neat winding and small winding diameter. However, due to the tight winding, pulling the winding shaft becomes a significant factor limiting the winding speed. Traditional tube-pulling machines have low pulling force, and the pulling process of the winding shaft in contact with the winding axis is unstable, frequently leading to malfunctions during both pulling and feeding of the winding shaft. Therefore, a tube-pulling machine with high pulling force and stable operation is needed. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, this utility model provides a multi-group linkage tube pulling mechanism.

[0004] This utility model is achieved through the following technical solution:

[0005] A multi-group linkage tube pulling mechanism includes a base, with support plates fixedly installed on both sides of the base. The mechanism is characterized in that: three sets of lower tube pulling wheels are installed on the lower part of the support plates, the lower tube pulling wheels are installed on the lower tube pulling shaft, and an upper tube pulling wheel is provided above the lower tube pulling wheels. Double rows of sprockets are respectively installed at the ends of the lower tube pulling shaft, and the diameter of the double rows of sprockets decreases sequentially from front to back.

[0006] The upper tube-pulling wheel is installed on the upper tube-pulling shaft, and both ends of the upper tube-pulling shaft are placed inside the lifting seat. The top of the lifting seat is connected to the hydraulic cylinder, the hydraulic cylinder is fixed to the top plate, and the top plate is fixed to the top of the support frame.

[0007] The lifting seat is secured on both sides to the guide rails of the support frame.

[0008] The beneficial effects of this utility model are: multiple rows of tube-pulling wheels simultaneously support the winding shaft, ensuring the operational stability of the winding shaft during the pulling out and feeding process; the pulling force is greatly improved, increasing the unwinding speed. Attached Figure Description

[0009] The present invention will be further described below with reference to the accompanying drawings.

[0010] Appendix Figure 1 This is a schematic diagram of the structure of this utility model;

[0011] In the diagram, 1 is the base, 2 is the support plate frame, 3 is the lower tube pulling wheel, 4 is the lower tube pulling shaft, 5 is the upper tube pulling wheel, 6 is the double row sprocket, 7 is the upper tube pulling shaft, 8 is the lifting seat, 9 is the hydraulic cylinder, 10 is the top plate, and 11 is the guide rail. Detailed Implementation

[0012] The attached figure shows a specific embodiment of this utility model. This embodiment includes a base 1, with support plates 2 fixedly mounted on both sides of the base 1. Three sets of lower tube-pulling wheels 3 are mounted on the lower part of the support plates 2, and the lower tube-pulling wheels 3 are mounted on a lower tube-pulling shaft 4. An upper tube-pulling wheel 5 is located above the lower tube-pulling wheels 3. Double-row sprockets 6 are respectively mounted on the ends of the lower tube-pulling shaft 4, with the diameter of the double-row sprockets 6 decreasing sequentially from front to back. The upper tube-pulling wheels 5 are mounted on an upper tube-pulling shaft 7, and both ends of the upper tube-pulling shaft 7 are placed inside a lifting seat 8. The top of the lifting seat 8 is connected to a hydraulic cylinder 9, which is fixed to a top plate 10. The top plate 10 is fixed to the top of the support plates 2. The two sides of the lifting seat 8 are engaged with guide rails 11 of the support plates 2.

[0013] This invention employs a multi-set linkage tube-pulling mechanism. The take-up shaft is positioned between the lower tube-pulling wheel 3 and the upper tube-pulling wheel 5. All three sets of puller wheels simultaneously support the take-up shaft, ensuring stability during pull-out and feed-in. The three rows of puller wheels are driven by a double-row sprocket 6, with each row rotating slightly faster than the previous one. This ensures a progressively increasing pulling force, improving the pulling speed and thus the unwinding speed, thereby increasing production efficiency. A hydraulic cylinder 9 drives the lifting seat 8 to move up and down, which in turn moves the upper tube-pulling shaft 7 and the upper tube-pulling wheel 5 up and down. Adjusting the gap between the lower tube-pulling wheel 3 and the upper tube-pulling wheel 5 allows for the pulling and feeding of take-up shafts of different diameters. The side of the lifting seat 8 is engaged with the guide rail 11, ensuring linear stability during its vertical movement.
