Description

Technical Field

[0001] This utility model relates to the technical field of greenhouse film threading equipment, specifically disclosing a threading device for greenhouse film production. Background Technology

[0002] Greenhouse film refers to special plastic film used in the construction of facility agriculture production. At present, the use of plastic greenhouse film is becoming more and more widespread, and it has been gradually promoted and applied to vegetable planting, fruit planting, aquaculture, poultry and livestock breeding, flower planting and other fields.

[0003] With the development of modern facility agriculture, the requirements for greenhouse films are becoming increasingly stringent. These requirements extend beyond service life, drip prevention, and dust control to include compatibility with machinery and equipment. One such requirement is the pre-welded edge of the greenhouse film before threading the ropes for overall movement. This pre-welded edge technology is widely used in large-scale planting bases across the country. Previously, threading the ropes required unfolding the film, using high-pressure, graded blowing to deliver thin traction ropes, and then threading the film-pulling ropes—a time-consuming and labor-intensive process. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a rope threading device for greenhouse film production, which can quickly connect the film pulling rope to the film and realize the rapid pulling of the film when laying the film, thereby reducing the rope threading cost for farmers and improving the laying efficiency.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] The aforementioned rope-threading device for greenhouse film production includes a main cylindrical tube and a film-pulling rope. A fixing plate is fitted at the upper end of the main cylindrical tube, and several threading rings are fixedly mounted on the fixing plate. A guide rod is fixedly mounted on the side of the main cylindrical tube, and several guide tubes are fixedly mounted on the guide rod at intervals. A knife holder is fixedly mounted at the top of the guide rod, and a blade is mounted on the knife holder. The film-pulling rope can pass through the threading rings and the guide tubes.

[0007] Furthermore, the fixing plate is wrapped in a semi-circular ring around the upper end of the main cylindrical tube.

[0008] Furthermore, the inner diameter of the fixing plate is adapted to the outer diameter of the main circular tube.

[0009] Furthermore, a limiting plate is fixedly installed at the bottom of the fixing plate, and the limiting plate is set perpendicular to the main circular tube.

[0010] Furthermore, the threading loop is designed in a semi-circular shape.

[0011] Furthermore, the outer diameter of the threading ring is adapted to the width of the fixing plate.

[0012] Furthermore, the inner diameter of the threading loop is larger than the diameter of the membrane rope.

[0013] Furthermore, the lead tube is arranged in a circular shape, and the outer wall of the lead tube is fixedly connected to the outer surface of the lead rod.

[0014] Furthermore, the inner diameter of the lead tube is larger than the diameter of the membrane rope.

[0015] Furthermore, a blade is fixedly connected to the side of the tool holder near the main body tube, and the blade is set perpendicular to the main body tube.

[0016] The beneficial effects of this utility model are:

[0017] This invention, through the design of a threading ring, a lead tube, and a blade, enables the film-pulling rope to be pulled to the same horizontal line as the cut film during film production. This allows for accurate and rapid installation of the film-pulling rope, improving production efficiency, facilitating subsequent film laying, increasing laying efficiency, reducing machine usage, saving production costs, and saving farmers time in threading the rope.

[0020] The present invention will now be described and explained in detail with reference to the accompanying drawings.

[0021] Example 1

[0022] like Figure 1 As shown, the rope-threading device for greenhouse film production includes a main cylindrical tube 1 and a film-pulling rope 2. A fixing plate 5 is provided at the upper end of the main cylindrical tube 1, and several threading rings 4 are fixedly provided on the fixing plate 5. A guide rod 8 is fixedly provided on the side of the main cylindrical tube 1, and several guide tubes 6 are fixedly provided at intervals on the guide rod 8. A knife holder 7 is fixedly provided at the top of the guide rod 8, and a blade 9 is provided on the knife holder 7. The film-pulling rope 2 can pass through the threading rings 4 and the guide tubes 6.

[0023] By setting up the threading ring 4, the lead tube 6, and the blade 9, the film-pulling rope 2 can be directly threaded into the film during film production, improving production efficiency and saving farmers the cost of threading the rope; by setting the film-pulling rope 2 to pass through the threading ring 4 and the lead tube 6, the film-pulling rope 2 can be limited, ensuring the stable operation of the device.

[0024] The fixing piece 5 is in the shape of a semi-circular ring wrapped around the upper end of the main cylindrical tube 1.

[0025] The inner diameter of the fixing plate 5 is adapted to the outer diameter of the main circular tube 1.

[0026] The above settings enable the fixing piece 5 to be secured to the main cylindrical tube 1 to prevent slippage.

[0027] A limiting plate 3 is fixedly installed at the bottom end of the fixing plate 5, and the limiting plate 3 is set perpendicular to the main circular tube 1. The limiting plate 3 can further limit the position of the film pulling rope 2, ensuring the stable operation of the device.

[0028] The threading ring 4 is set in a semi-circular shape.

[0029] The outer diameter of the threading ring 4 is adapted to the width of the fixing piece 5.

[0030] The inner diameter of the threading ring 4 is larger than the diameter of the membrane rope 2.

[0031] The lead tube 6 is arranged in a circular shape, and the outer wall of the lead tube 6 is fixedly connected to the outer surface of the lead rod 8.

[0032] The inner diameter of the lead tube 6 is larger than the diameter of the membrane rope 2.

[0033] After passing through the threading ring 4 and the lead tube 6, the membrane rope 2 is fixedly connected to the membrane.

[0034] The blade 9 is fixedly connected to the side of the tool holder 7 near the main body tube 1, and the blade 9 is set perpendicular to the main body tube 1.

[0035] Working principle and process:

[0036] After the main cylindrical tube 1 is installed at a certain position on the edge-bonding machine and fixed, the film is pulled and cut by the blade 9 to form an opening. The film-pulling rope 2 is passed through the threading ring 4 and the lead tube 6 and placed on one edge of the film. The film and the film-pulling rope 2 are aligned and then welded by the edge-bonding machine to lock the film-pulling rope 2 inside the film. When the film is cut, the film-pulling rope 2 can always be flush with the film, completing the online flow rope threading.
