Description

Technical Field

[0001] This utility model relates to the field of polyethylene rope cutting technology, and in particular to an agricultural polyethylene rope cutting device. Background Technology

[0002] In agricultural production and daily use, polyethylene ropes are widely used in various scenarios such as crop tying, greenhouse construction, and material securing due to their good tensile strength, corrosion resistance, and lightweight and easy-to-use properties. With the continuous improvement of agricultural mechanization, higher requirements are being placed on the processing efficiency and cutting precision of polyethylene ropes.

[0003] Currently, in practical applications, cutting devices used for polyethylene ropes generally suffer from simple structures and limited functionality. Traditional methods often employ manual shearing or simple blades for cutting, which is not only inefficient but also results in inconsistent cutting lengths, poor operational safety, and a tendency for the rope to slip or shift, or for the cut end to be uneven, affecting subsequent use. Furthermore, the lack of effective positioning and tensioning structures before cutting allows the rope to easily shift or even retract during pulling or cutting, impacting cutting accuracy and operational continuity.

[0004] To address the aforementioned issues, an agricultural polyethylene rope cutting device is proposed. This device features precise positioning, efficient cutting, and anti-slip and anti-retraction functions to meet the demands of modern agricultural production for rapid, high-quality cutting of polyethylene ropes, thereby improving work efficiency and safety.

[0012] This utility model provides an agricultural polyethylene rope cutting device, which, compared with the prior art, has the following advantages:

[0013] 1. This utility model automatically winds up a polyethylene rope using a take-up roller, pulling one end of the rope into a groove. Inside the groove, positioning wheels and springs precisely position both sides of the rope, ensuring stability during cutting and unimpeded smooth pulling. This not only improves operational convenience but also guarantees the accuracy of the rope's position during cutting, avoiding cutting errors caused by rope misalignment. Furthermore, two sets of cylinders drive the upper and lower cutting blades to move relative to each other, achieving efficient and precise cutting of the rope, thus improving overall work efficiency and cutting quality.

[0014] 2. This utility model includes a positioning platform and a positioning plate to fix the rope section to be cut, ensuring its stability during the cutting process. The positioning plate has a toothed structure, which enhances the gripping force of the rope and prevents it from slipping or moving during cutting. Furthermore, after cutting, it effectively prevents the rope from retracting, ensuring that the cut rope segment remains in the predetermined position. Attached Figure Description

Detailed Implementation

[0024] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0025] Please refer to Figures 1-6 This utility model provides an agricultural polyethylene rope cutting device, including a movable base 1, with a winding roller 7 rotatably mounted on the upper end of the movable base 1. The winding roller 7 is used to wind up and store the polyethylene rope, which is convenient for subsequent pulling and cutting operations.

[0026] Furthermore, a support plate 8 is bolted to one side of the movable base 1. A rotating hole is provided at the upper end of the support plate 8, into which one end of the take-up roller 7 is inserted and rotatably positioned, thus supporting the other end of the take-up roller 7. This effectively improves the stability of the take-up roller 7 during rotation, preventing uneven rope winding or obstructed pulling due to swaying. Simultaneously, the support plate 8 is bolted to the movable base 1, facilitating disassembly and maintenance, and enhancing the practicality and maintainability of the device.

[0027] In addition, an extension plate 2 is fixedly installed on the other side of the movable seat 1, and a groove 3 is formed inside the extension plate 2. A rope positioning mechanism is provided at one end of the groove 3 for preliminary positioning and guidance of the pulled-out polyethylene rope. Specifically, multiple slide rods 4 are slidably arranged on the two side walls of the groove 3. One end of the slide rod 4 is connected to a positioning wheel 5, and the other end extends into the groove 3 and is fitted with a spring 6 on its outside, so that the positioning wheel 5 can automatically contact the surface of the rope under the action of elasticity.

[0028] Furthermore, the device also includes a rope positioning mechanism at one end of the extension plate 2, which is used to clamp and fix the pulled-out polyethylene rope so that the rope cutting mechanism can perform a precise cutting operation later.

[0029] like Figure 4 As shown, the rope positioning mechanism includes a positioning platform 9 fixedly mounted on the extension plate 2. The positioning platform 9 has an arc groove 10, the shape of which matches the outer contour of the polyethylene rope, facilitating rope placement and maintaining stability. A fixing plate 11 is provided on one side of the positioning platform 9, and sliding grooves 12 are provided on both sides of the fixing plate 11. A positioning plate 15 is slidably installed within the sliding grooves 12. By moving the positioning plate 15 downwards, it presses against the upper surface of the polyethylene rope, thereby firmly clamping the rope within the arc groove 10.

[0030] Furthermore, teeth 16 are provided at the lower groove of the positioning plate 15 to enhance the friction between it and the polyethylene rope, prevent the rope from slipping or retracting during the cutting process, and improve the cutting stability and safety.

[0031] One of the slides 12 contains a lead screw 17 that is rotatably mounted, and the lead screw 17 is threadedly connected to one side of the positioning plate 15. By rotating the lead screw 17, the positioning plate 15 can be smoothly adjusted up and down, thereby facilitating the clamping or releasing operation of the rope.

[0032] In addition, the rope cutting mechanism includes an upper cutting blade 19 and a lower cutting blade 18, which are slidably disposed in the second groove 13 opened on the fixed plate 11 and are arranged in a staggered manner. Although the upper cutting blade 19 and the lower cutting blade 18 also slide in the second groove 13, the lengths of their sliding positions inside the second groove 13 are different. Therefore, the staggered arrangement of the upper cutting blade 19 and the lower cutting blade 18 can be satisfied. During cutting, the two sets of cylinders 20 drive the upper cutting blade 19 and the lower cutting blade 18 to move toward each other, thereby realizing the efficient cutting operation of the fixed polyethylene rope.

[0033] To enhance equipment safety and prevent debris from flying or accidentally touching the cutting tools during the cutting process, a protective plate 14 is provided on the outside of the fixing plate 11. This plate is used to shield and protect the upper cutting blade 19 and the lower cutting blade 18, while also serving as a structural support and aesthetic enhancement.

[0034] In summary, the working principle of the agricultural polyethylene rope cutting device of this utility model embodiment is as follows: First, the polyethylene rope is wound around the take-up roller 7 on the movable seat 1, and the take-up roller 7 is stably supported by the rotating hole of the support plate 8. Then, one end of the rope is pulled through the groove 3 in the extension plate 2, and is initially positioned by the sliding positioning wheel 5 and the spring 6. Next, the rope is placed in the arc groove 10 of the positioning platform 9, and the positioning plate 15 is used to press the rope down. The teeth 16 on the lower side of the positioning plate 15 enhance the friction and prevent slippage. The height of the positioning plate 15 is adjusted by rotating the lead screw 17 to clamp or release the rope. After the rope is fixed, the rope cutting mechanism is activated. The two sets of cylinders 20 drive the upper cutting blade 19 and the lower cutting blade 18 to move towards each other, completing the efficient cutting.

[0035] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
