Description

Technical Field

[0001] This utility model relates to the technical field of waste rubber recycling and cutting equipment, specifically a waste rubber tire cutting tool. Background Technology

[0002] As we all know, the rubber materials in different parts of waste tires are different. Different recycling processes are used for different rubber materials, resulting in different rubber properties. If waste tires are simply crushed as a whole and processed in the same way, the resulting rubber is a mixture of materials with unstable properties and high recycling costs. In order to classify and recycle the rubber of different parts and materials of waste tires, cutting equipment is often used to cut and separate the different parts of waste tires, and then recycle them separately.

[0003] A search revealed that Chinese Patent Publication No. CN212241727U discloses a waste rubber tire cutting tool, which includes a polygonal tool body with a certain thickness. Several cutting heads are arranged circumferentially on the tool body. Both the tool body and the cutting heads are made of metal. Each cutting head is set at an obtuse angle to the inclined side of the tool body. A tensioning device is provided in the middle of the tool body for mounting on the rotating shaft of a cutting device. This utility model uses a non-self-wear cutting method, does not generate dust during cutting, and has a tensioning device that prevents loosening and chipping, ensuring good safety. The cutting heads are not easily stuck to the rubber at high temperatures, resulting in high cutting efficiency. It is applicable to the field of waste rubber recycling cutting equipment technology.

[0004] Although the above technical solution solves the problem of high cutting efficiency, the existing tire cutters come in various specifications, and the diameter of the rotating shaft of different specifications of cutters is also different. At this time, it is necessary to replace the blades with different hole diameters, which is costly. Utility Model Content

[0005] Technical problems to be solved

[0006] In order to overcome the problem that existing waste rubber tire cutting tools cannot adapt to different shaft diameters, this utility model provides a waste rubber tire cutting tool that can adapt to shafts of different specifications.

[0007] Technical solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a waste rubber tire cutting tool, comprising:

[0009] blade;

[0010] An adjustment assembly is mounted on the side of the blade. The adjustment assembly includes a fixed plate with at least three fixed seats fixedly disposed on it. Each fixed seat has a sliding groove. A turntable is rotatably disposed on the fixed plate. Rotating rods corresponding to the number of fixed seats are evenly fixed to the top of the turntable. One end of each rotating rod slides against the inner wall of the sliding groove. A handle is fixedly disposed on one side of the turntable.

[0011] A limiting component is mounted on the handle.

[0012] Preferably, the adjustment assembly further includes a support frame, which is fixedly mounted on the top of the turntable, and the bottom of the support frame is rotatably mounted to the top of the rotating rod.

[0013] Furthermore, small holes are provided on the fixed plate, the turntable, and the support frame, and the diameter of the small holes is the same as the diameter of the blade.

[0014] Furthermore, the other end of the rotating rod is circular.

[0015] In a further embodiment, the limiting component includes a limiting plate, which is slidably disposed on the handle. A limiting ring is threaded onto the handle and fits against the limiting plate. Anti-slip rubber is fixedly disposed on the inner wall of the limiting plate, and the anti-slip rubber and the inner wall of the limiting ring fit against the fixed plate.

[0016] Based on the aforementioned scheme, the shape of the limiting plate is an arc shape adapted to the fixed plate.

[0017] Based on the aforementioned scheme, each of the fixing seats is evenly distributed in a circle on the fixing plate, and the included angle between adjacent fixing seats is equal.

[0018] Beneficial effects

[0019] This waste rubber tire cutting tool features a coordinated structure in its adjustment assembly, including a fixed disc, fixed seat, slide groove, turntable, and rotating rod. When mounting the blade on shafts of different diameters, the operator can rotate the handle to turn the turntable. Since one end of the rotating rod slides within the slide groove, this structure allows for dynamic adjustment of the blade's center bore diameter within a certain range. For example, when facing a shaft with a smaller diameter, rotating the handle reduces the blade's center bore diameter, while rotating the handle in the opposite direction increases the bore diameter for a larger diameter shaft. This allows the blade to adapt to various shaft sizes, eliminating the need for frequent blade replacements. Adjusting the bore diameter by rotating the turntable with the handle is simple and direct. Compared to replacing blades with different bore diameters, this adjustment method is more time-saving and labor-saving, significantly improving work efficiency in actual production. Workers can easily adjust the bore diameter by simply rotating the handle, reducing downtime for blade replacements and improving overall production progress. Attached Figure Description

[0027] 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.

[0028] See Figures 1-6 A waste rubber tire cutting tool includes a blade 1, an adjustment component 2, and a limiting component 9.

[0029] The adjustment assembly 2 is installed on the side of the blade 1 and includes a fixed plate 3, a fixed seat 4, a turntable 6, a rotating rod 7, and a handle 8. The fixed plate 3 is the basic support structure of the adjustment assembly 2, and at least three fixed seats 4 are fixed on it. Each fixed seat 4 has a groove 5, which provides a track for the sliding of the rotating rod 7, ensuring the stability of the rotating rod 7 during movement. The turntable 6 is rotatably mounted on the fixed plate 3 and can move in a circular motion around the center of the fixed plate 3. The top of the turntable 6 has rotating rods 7 evenly distributed, corresponding to the number of fixed seats 4. One end of the rotating rod 7 is tightly fitted to the inner wall of the groove 5 and can slide freely. When the operator rotates the turntable 6, the rotating rod 7 will move along the direction of the groove 5. The rotating rod 7 has a circular end, which increases the contact area with the rotating shaft. When the tool is installed on the cutting machine, the larger contact area makes the connection between the blade 1 and the cutting machine tighter and more stable, effectively reducing the wobbling or displacement of the blade 1 during the cutting process, thus ensuring the accuracy and quality of the cutting. A handle 8 is fixedly installed on one side of the turntable 6. The operator can rotate the turntable 6 by holding the handle 8. The handle 8 provides the operator with a convenient way to operate, allowing them to easily control the rotation of the turntable 6, which in turn drives the rotating rod 7 to slide in the groove 5, realizing flexible adjustment of the relevant parameters of the tool to meet different cutting requirements.

[0030] First, refer to Figure 3 In this embodiment, the adjustment component 2 also includes a support frame 10. The support frame 10 in the adjustment component 2 is fixedly installed on the top of the turntable 6, and its bottom is rotatably connected to the top of the rotating rod 7. The support frame 10 plays a role in further stabilizing the rotating rod 7. When the turntable 6 rotates and drives the rotating rod 7 to slide in the slide groove 5, the support frame 10 can constrain the movement trajectory of the rotating rod 7, making it more stable. At the same time, this rotatable connection method ensures that the rotating rod 7 can flexibly change its angle during the movement, ensuring the smoothness of the adjustment process.

[0031] Then, refer to Figure 3 In this embodiment, small holes 11 are provided on the fixed plate 3, the turntable 6 and the support frame 10, and the diameter of these small holes 11 is the same as the diameter of the blade 1. The function of these small holes 11 is to facilitate the use of bolts and other connecting parts to pass through when installing the blade 1, so as to firmly connect the blade 1, the fixed plate 3, the turntable 6 and the support frame 10 together. In this way, the adjusting component 2 and the blade 1 can be tightly integrated into a whole, ensuring that there is no relative displacement between the components during the cutting process, thereby improving the stability and accuracy of the cutting.

[0032] Finally, see Figure 5 and Figure 6 In this embodiment, the limiting component 9 mainly consists of a limiting plate 12, a limiting ring 13, and anti-slip rubber 14. The limiting plate 12 is slidably mounted on the handle 8, and its shape is an arc adapted to the fixed plate 3. This arc design allows the limiting plate 12 to better fit the outer contour of the fixed plate 3. When it is necessary to lock the adjusted state, the limiting plate 12 is slid to bring it closer to the fixed plate 3. The limiting ring 13 is provided on the handle 8 by threads. When the limiting ring 13 is rotated, it will move along the thread direction of the handle 8. The limiting ring 13 fits against the limiting plate 12. By rotating the limiting ring 13, the limiting plate 12 can be pushed further closer to the fixed plate 3. Anti-slip rubber 14 is fixedly provided on the inner wall of the limiting plate 12. The anti-slip rubber 14 and the inner wall of the limiting ring 13 fit against the fixed plate 3. The anti-slip rubber 14 increases the friction between the limiting plate 12 and the limiting ring 13 and the fixed plate 3. When the limiting ring 13 pushes the limiting plate 12 to fit tightly against the fixed plate 3, the anti-slip rubber 14 effectively prevents the limiting plate 12 and the limiting ring 13 from sliding, thereby fixing the handle 8 and the turntable 6, maintaining the adjusted state of the blade 1, and ensuring stable cutting operations. The fixed seats 4 are evenly distributed circumferentially on the fixed plate 3, and the included angle between adjacent fixed seats 4 is equal. This included angle is the value obtained by dividing 360° by the number of fixed seats 4. This distribution ensures that when the turntable 6 rotates and drives the rotating rod 7 to slide in the slide groove 5, the force on each rotating rod 7 is uniform, ensuring a smooth and precise adjustment process for the center hole diameter of the blade 1, thereby effectively adapting to different specifications of rotating shafts and ensuring the stability of cutting operations.

[0033] Working principle:

[0034] The waste rubber tire cutting tool is first operated by a worker who holds the handle 8 of the adjusting component 2 and rotates the turntable 6 according to the diameter of the rotating shaft. If the diameter of the rotating shaft is small, the handle 8 is rotated clockwise. At this time, the turntable 6 drives the rotating rod 7 to slide in the slide groove 5 of the fixed seat 4, so that the center hole diameter of the blade 1 is reduced. If the diameter of the rotating shaft is large, the handle 8 is rotated counterclockwise to increase the hole diameter. During the rotation, the support frame 10 helps to stabilize the rotating rod 7 to ensure smooth and accurate adjustment. The limiting plate 12 of the sliding limiting component 9 is brought closer to the fixed plate 3. Then the limiting ring 13 on the handle 8 is rotated. The limiting ring 13 moves along the thread and pushes the limiting plate 12, so that the anti-slip rubber 14 on the inner wall of the limiting plate 12 is tightly attached to the inner wall of the limiting ring 13 to the fixed plate 3. The friction locks the handle 8 and the turntable 6 to prevent the adjusted hole diameter of the blade 1 from changing. The cutting equipment with the blade installed is started, and different parts of the tire are cut and separated according to the waste rubber tire cutting process requirements.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
