Description

Technical Field

[0001] This utility model relates to the field of ton bag cutting tools, and in particular to solid asphalt ton bag cutting tools. Background Technology

[0002] Solid asphalt is hard and brittle at room temperature, and needs to be heated to its softening point of 50-80℃ to turn into a liquid. It has extremely high viscosity and a very slow flow rate, sometimes taking years to drip a single drop. Solid asphalt does not have a fixed melting point, but it can be softened by heating. Its softening point is usually above 40-100℃, depending on the type of asphalt and the processing technology. For example, in road paving, asphalt is often heated to 180℃ to liquefy it.

[0003] Ton bag breaker blades are a powerful assistant in the industrial field. In industrial production, ton bag breaker blades are an indispensable tool. With their high efficiency, durability, and precision, they have become a powerful helper in many industries. The main function of ton bag breaker blades is to cut and break open large ton bags. In industrial production, ton bags are specially designed for asphalt granules or powdery materials to achieve a sealed opening. The ton bag breaker blades easily cut open the ton bags through high-speed rotation or reciprocating motion, allowing the material to flow out quickly.

[0004] In existing technologies, wallpaper cutters are used when cutting bags, but these are inefficient and unsuitable for substances with high viscosity such as solid asphalt. Furthermore, due to the high viscosity of solid asphalt and the high temperature of the asphalt pool, workers face operational risks during bag cutting operations. Summary of the Invention

[0005] The purpose of this utility model is to provide a tool for cutting solid asphalt ton bags, which can extend the length of the blade through the handle, and at the same time hide the blade edge through the protective sleeve, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a solid asphalt cutting tool for ton bags, including a cutting component. The cutting component includes a handle, and an installation groove is provided inside the left side of the handle. Through holes are arranged in parallel on the left side of the outer surface of the installation groove. A blade is slidably connected inside the installation groove. Connecting posts are inserted into the upper and lower sides of the through holes. The ends of the upper and lower connecting posts are pressed together. A threaded groove is provided on the upper side of the lower connecting post. A threaded post is fixedly connected to the lower end of the upper connecting post. After the threaded post moves downward, it is threadedly connected to the threaded groove. A protective sleeve is slidably connected to the outside of the blade. A retaining groove is provided inside the protective sleeve, and the blade is engaged inside the retaining groove.

[0007] Preferably, the mounting groove is connected to the through hole, the shape of the blade is adapted to the shape of the slot, and the connecting post passes through the blade.

[0008] Preferably, connecting rods are fixedly connected to both the front and rear sides of the right end of the blade, and a sleeve is fixedly connected to the right side of both the front and rear connecting rods. The sleeve is slidably connected to the outside of the handle after it moves.

[0009] Preferably, the left half of the grip is frustum-shaped, and the sleeve is fitted onto the left half of the grip after the sleeve is moved. The shape of the left half of the grip is adapted to the shape of the right half of the slot.

[0010] Preferably, the inner and outer sides of the grip are provided with a locking component, the locking component including a positioning groove that extends through the upper side of the sleeve.

[0011] Preferably, movable grooves are provided on both the left and right sides of the upper end of the handle, and a locking block is slidably connected inside the movable groove. A pressure spring is fixedly connected between the lower side of the locking block and the lower side of the inner interior of the movable groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The blade is surrounded by a protective sleeve, and the working range of the blade is extended by the handle. Since the blade used to cut the ton bag is connected by the handle, the distance between the worker's palm and the ton bag is increased, reducing the possibility of the worker being injured by solid asphalt. At the same time, after the ton bag is cut, the blade can be hidden by the protective sleeve to prevent the blade from causing injury to the worker.

[0016] 2. The sleeve is restricted by the locking block after it moves, so that the protective sleeve is stably surrounded by the outside of the blade. Since the protective sleeve hides the blade edge, the locking block can limit the sleeve. At this time, the protective sleeve cannot automatically detach from the outside of the blade, effectively preventing the protective sleeve from falling off the blade, thus ensuring the concealment effect of the protective sleeve on the blade edge.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides a technical solution:

[0026] Please see Figures 1 to 4A tool for cutting ton bags of solid asphalt includes a cutting component 1, which includes a handle 11. The handle 11 has an installation groove 12 inside its left side. The left side of the outer surface of the installation groove 12 has through holes 13 arranged in parallel. A blade 14 is slidably connected inside the installation groove 12. Connecting posts 15 are inserted into the upper and lower sides of the through hole 13. The ends of the upper and lower connecting posts 15 are pressed together. A threaded groove 16 is opened on the upper side of the lower connecting post 15. A threaded post 17 is fixedly connected to the lower end of the upper connecting post 15. After the threaded post 17 moves downward, it is threadedly connected to the threaded groove 16. A protective sleeve 18 is slidably connected to the outside of the blade 14. A slot 19 is opened inside the protective sleeve 18. The blade 14 is engaged inside the slot 19.

[0027] The mounting groove 12 is connected to the through hole 13, the shape of the blade 14 is adapted to the shape of the slot 19, and the connecting post 15 passes through the blade 14.

[0028] The front and rear sides of the right end of the blade 14 are fixedly connected to the connecting rod 2. The right side of the front and rear connecting rods 2 is fixedly connected to the sleeve 3. After the sleeve 3 moves, it slides to the outside of the handle 11.

[0029] The left half of the grip 11 is truncated cone-shaped. After the sleeve 3 moves, it is fitted onto the left half of the grip 11. The shape of the left half of the grip 11 matches the shape of the right half of the slot 19.

[0030] By adopting the above technical solution, the blade 14 is aligned with the mounting groove 12 on the left side of the handle 11. Then, the connecting post 15, which has threaded posts 17 and threaded grooves 16, is inserted into the through holes 13 on the upper and lower sides of the handle 11. Next, the connecting post 15 with threaded posts 17 is turned, and the connecting post 15 with threaded grooves 16 is supported. When the two threaded posts 17 and threaded grooves 16 are fully engaged, the two connecting posts 15 will also penetrate the blade 14, locking the blade 14 inside the mounting groove 12. After the blade 14 has finished cutting the package, push... The sleeve 3 on the outside of the handle 11 is moved so that the handle 11 pushes the protective sleeve 18 through the connecting rod 2, so that the protective sleeve 18 wraps around the outside of the blade 14 from the outside of the handle 11 and wraps around the blade edge of the blade 14. Since the blade 14 used to cut the ton bag is connected through the handle 11, the distance between the worker's palm and the ton bag is increased, reducing the possibility of the worker being injured by solid asphalt. At the same time, after the ton bag is cut, the blade 14 can be hidden by the protective sleeve 18, which can prevent the blade 14 from causing injury to the worker.

[0031] Specifically, such as Figure 3 and Figure 4 As shown, the inner and outer sides of the grip 11 are provided with locking components 4, and the locking components 4 include a positioning groove 41 that passes through the upper side of the sleeve 3.

[0032] The upper end of the handle 11 has movable grooves 42 on both the left and right sides. A locking block 43 is slidably connected inside the movable groove 42. A pressure spring 44 is fixedly connected between the lower side of the locking block 43 and the lower side of the movable groove 42. After the locking block 43 moves upward, it locks into the inside of the positioning groove 41.

[0033] The upper right side of the locking block 43 is provided with an inclined surface. The inclined surface of the locking block 43 slides and presses against the inner right side wall of the positioning groove 41. The shape of the locking block 43 is adapted to the shape of the positioning groove 41.

[0034] Limiting plates 45 are fixedly connected to both the upper and lower sides of the handle 11, and the left side of the sleeve 3 is in contact with the right side of the limiting plate 45.

[0035] By adopting the above technical solution, when it is necessary to remove the hidden blade 14, the locking block 43 can be pressed down through the positioning groove 41, causing the locking block 43 to retract into the movable groove 42 and compress the pressure spring inside the movable groove 42. After the locking block 43 is completely disengaged from the positioning groove 41, the positioning groove 41 loses the restriction from the locking block 43. At this time, the sleeve 3 can slide on the outside of the handle 11. When the locking block 43 on the right side is pushed into the positioning groove 41 by the pressure spring 44, the locking block 43 re-limits the sleeve 3. At this time, the protective sleeve 18 fixed by the connecting rod 2 will slide on the outside of the blade 14, and Finally, the sleeve is placed on the outside of the handle 11. When it is necessary to hide the blade 14, the sleeve 3 can be pushed directly so that the inner wall of the positioning groove 41 contacts the inclined surface of the locking block 43, and the locking block 43 is pushed directly into the movable groove 42 until the left side of the sleeve 3 contacts the limiting plate 45. At this time, the protective sleeve 18 completely hides the blade edge of the blade 14. Since the locking block 43 can limit the sleeve 3 after the protective sleeve 18 hides the blade edge of the blade 14, the protective sleeve 18 cannot automatically detach from the outside of the blade 14, effectively preventing the protective sleeve 18 from falling off the blade 14, thus ensuring the hiding effect of the protective sleeve 18 on the blade edge of the blade 14.

[0036] Working principle: The blade 14 is locked inside the mounting slot 12 via the connecting post 15. When it is necessary to remove the hidden blade 14, the locking block 43 can be pressed down through the positioning slot 41, causing the locking block 43 to retract into the movable slot 42 and compress the pressure spring inside the movable slot 42. After the locking block 43 is completely disengaged from the positioning slot 41, the positioning slot 41 loses the restriction from the locking block 43. At this time, the sleeve 3 can slide on the outside of the handle 11. When the locking block 43 on the right side is compressed by the pressure spring 44... After being pushed into the positioning groove 41, the locking block 43 repositions the sleeve 3. At this time, the protective sleeve 18, which is fixed by the connecting rod 2, slides on the outside of the blade 14 and eventually fits on the outside of the handle 11. When it is necessary to hide the blade 14, the sleeve 3 can be pushed directly so that the inner wall of the positioning groove 41 contacts the inclined surface of the locking block 43, and the locking block 43 is pushed directly into the movable groove 42 until the left side of the sleeve 3 contacts the limiting plate 45. At this time, the protective sleeve 18 completely hides the blade edge of the blade 14.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
