Technical Field

[0001] This utility model relates to the field of spinning tool technology, and in particular to a spinning hook knife. Background Technology

[0002] Polyester fibers account for a large proportion of the synthetic fiber industry. Conventional polyester fibers can no longer meet the diversity requirements of modern technology. Therefore, in recent years, the development of differentiated polyester fibers has received more and more attention from industry professionals. Due to the novelty and special nature of differentiated fibers, the product quality often does not reach a high level during the development stage, resulting in a large number of substandard products that need to be processed. During processing, hooks are needed to hook and cut the fibers.

[0003] Currently, the widely used spinning hooks often have exposed blades that are difficult to grip, posing safety hazards to employees when stripping yarn. They are also difficult to grip firmly, inconvenient to carry, and prone to causing cuts, resulting in accidents and wasted time. Therefore, a new technical solution is urgently needed to address at least one of these problems. Summary of the Invention

[0004] In view of the above shortcomings, the purpose of this utility model is to provide a spinning hook knife that increases the force-bearing effect and safety performance of the hook knife, reduces safety hazards, and improves the efficiency of wire cutting.

[0005] To achieve the above-mentioned technical objectives and meet the above-mentioned technical requirements, the technical solution adopted by this utility model is as follows: A spinning hook knife, comprising: The knife handle has finger grooves and grooves on its outer surface. The finger grooves are concave arc structures, and the grooves are spiral grooves with an arc-shaped cross-section. One end of the knife handle is connected to a knife shank, and the free end of the knife shank is equipped with a cutting tool. One end of the knife handle is threadedly connected to a knife cover, and both the knife shank and the cutting tool are located inside the knife cover.

[0016] The present invention will now be further described with reference to the accompanying drawings.

[0017] In the accompanying drawings of this utility model, the same or similar reference numerals correspond to the same or similar components. In the description of this utility model, it should be understood that if terms such as "top," "bottom," "left," "right," "front," "rear," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this utility model, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0018] Please refer to Figures 1-5 One embodiment of this utility model provides a spinning hook knife, comprising: The knife handle 1 has finger grooves 2 and grooves 3 on its outer surface. The finger grooves 2 have an inwardly concave arc structure, and the grooves 3 have a spiral groove structure with an arc-shaped cross-section. The knife handle 1 is used for the operator to grip. The purpose of the finger grooves 2 is to position the fingers and reduce slippage during gripping. The inwardly concave arc structure of the finger grooves 2 allows them to conform to the natural curvature of the fingers, while avoiding being too deep and causing discomfort or too shallow and losing their positioning function. The grooves 3 are designed to increase the friction when the hand grips the knife handle 1, improving the stability of the grip. The grooves 3 have a spiral structure. The groove 3 has an arc-shaped cross-section to avoid right-angle grooves (which are uncomfortable to hold and accumulate dirt). It should also be avoided to prevent excessive depth from reducing the strength of the handle 1. Preferably, the groove 3 uses a coarse thread, suitable for withstanding impact or vibration loads and less prone to slippage due to excessive localized force. One end of the handle 1 is connected to a tool shank 4, and the free end of the tool shank 4 has a cutting tool 5. One end of the handle 1 is threadedly connected to a tool cover 6. Both the tool shank 4 and the cutting tool 5 are located inside the tool cover 6. Preferably, the tool shank 4 has a certain length, suitable for small-range curved cutting or fine engraving. The blade is designed for easy control, concentrating power at the fingertips. The blade itself has a gentle, curved shape, resembling a crescent moon. Since most silk cakes are cylindrical and coiled, the curved blade conforms to their surface curvature, ensuring even force distribution during cutting and preventing excessive force in certain areas from causing the silk threads to clump and break. The tip of the blade is beveled (not a sharp angle, but a slightly blunt cut), allowing it to easily insert into gaps in the silk layers and separate the threads through a "picking-cutting" motion (rather than forcefully piercing). This is especially suitable for tightly coiled silk cakes, reducing tangling. The blade is relatively thin, with a sharp but not overly pointed tip to avoid piercing too deeply and snagging the thread. The rear end of the blade is slightly wider (to enhance strength), and the transition at the connection with the handle is smooth, reducing hand obstruction during operation. When not in use, the cover 6 is threaded onto the handle 1, thus hiding the handle 4 and the knife 5 for safe carrying and handling without causing injury. To use, simply turn the knob to remove the cover 6. The threaded connection between the cover 6 and the handle 1 facilitates installation and removal, thus improving convenience.

[0019] In this solution, the structure of the handle 1 and the threaded connection of the cover 6 make the hook knife easy for employees to carry and use, and improve the grip and force distribution, which can improve the efficiency of wire cutting and avoid safety accidents to a certain extent.

[0020] like Figure 1 , Figure 2 and Figure 5 As shown, the other end of the handle 1 is equipped with a connector 7. The knife cover 6 is threadedly connected to the connector 7. When using the hook knife, the knife cover 6 is first removed from the handle 1 to expose the knife bar 4 and the knife 5, which makes it easier to hook and cut shreds. Then the knife cover 6 is connected to the other end of the handle 1 through the connector 7, so that the knife cover 6 does not need to be stored separately and is less likely to be lost.

[0021] like Figure 1 , Figure 4 and Figure 5 As shown, a hand rope 8 is connected to the knife cover 6. By connecting the hand rope 8 to the knife cover 6, when the hook knife is not in use, the knife cover 6 can hide and store the knife bar 4 and the knife 5, and the hook knife can be better carried by the hand rope 8. At the same time, in the work environment, the hook knife can also be hung near the work station by the hand rope 8 for easy access at any time.

[0022] like Figure 2 and Figure 5 As shown, a connecting plate 9 is fixed to one end of the tool holder 1. The connecting plate 9 and the tool bar 4 are fixed by the cooperation of bolts 10 and nuts 11. Preferably, both the connecting plate 9 and the tool bar 4 have through holes. The tool bar 4 and the connecting plate 9 are fitted together, and the through holes on the two are aligned. The end of the bolt 10 is moved through the two through holes. Then, the nut 11 is threaded onto the bolt 10 and the nut 11 is tightened, thereby fixing the tool bar 4 and the connecting plate 9. This makes the tool bar 4 and the tool holder 1 detachably connected, which is convenient for replacing the tool bar 4 or for sharpening the cutting edge of the tool 5.

[0023] like Figure 5 As shown, the connecting plate 9 has a slot 12, and the tool bar 4 is inserted into the slot 12. By opening the slot 12 on the connecting plate 9, when installing the tool bar 4, the tool bar 4 is first movably inserted into the slot 12, which facilitates alignment with the through hole of the connecting plate 9. At the same time, the insertion method of the tool bar 4 and the slot 12 can not only further improve the connection between the tool bar 4 and the connecting plate 9, but also effectively fix the tool bar 4 with only a set of bolts 10 and nuts 11.

[0024] like Figure 2 and Figure 5As shown, a column 13 is fixed on the knife cover 6, and a hexagonal groove 14 is provided on the column 13. Preferably, the nut 11 is inserted into the hexagonal groove 14. By constructing the column 13 on the knife cover 6 and providing the hexagonal groove 14 on the column 13, the knife cover 6 can not only shield and protect the knife bar 4 and the knife 5, but also serve as a disassembly tool to facilitate the disassembly of the nut 11.

[0025] like Figure 3 and Figure 5 As shown, a rubber sleeve 15 is fixed to the open end of the blade cover 6. The outer surface of the rubber sleeve 15 is arrayed with several anti-slip protrusions 16. By fixing the rubber sleeve 15 to the blade cover 6 and constructing anti-slip protrusions 16 on the rubber sleeve 15, friction is increased when unscrewing (screwing in), making it easier to open (close) the blade 5. At the same time, when tightening the blade cover 6, the blade cover 6 and the blade handle 1 will squeeze the rubber sleeve 15, so that the rubber sleeve 15 acts as a seal to prevent fiber dust and liquid in the workshop environment from seeping into the blade cover 6 and corroding the blade.

[0026] like Figure 3 and Figure 4 As shown, a rubber pad 17 is fixed inside the finger groove 2. Several anti-slip protrusions 18 are arrayed on the rubber pad 17. By setting the rubber pad 17 inside the finger groove 2 and constructing anti-slip protrusions 18 on the rubber pad 17, the friction of the fingertip is further increased, which makes it easier to control the cutting wire.

[0027] Any numerical values ​​cited herein include all values ​​ranging from a lower limit to an upper limit, increasing by one unit, with at least two units between any lower and any higher value. For example, if the quantity of a component or the value of a process variable (e.g., temperature, pressure, time, etc.) is described as being from 1 to 90, preferably from 20 to 80, more preferably from 30 to 70, the purpose is to illustrate that values ​​such as 15 to 85, 22 to 68, 43 to 51, 30 to 32 are also explicitly listed in this specification.
