Description

Technical Field

[0001] This utility model relates to the field of plastic crushing technology, and in particular to a crushing tool and a crusher. Background Technology

[0002] A plastic crusher is a device used to crush plastic waste or plastic products into small particles. It is widely used in the plastic recycling industry and waste treatment. Its working principle is to use mechanical force to crush the plastic material, reducing its volume for easier further processing or reuse.

[0003] Traditional plastic crushers process plastics by first feeding it into the inlet. After entering the crusher, the plastic falls into the lower feed box and is tumbled by the blade holder on the rotating shaft. During this tumbling, the plastic randomly falls between the moving blades mounted on the blade holder and the positioning blades on the feed box. The two work together to cut the plastic material into small pieces or granules through shearing and compression, thus achieving the processing and crushing of the plastic. However, in actual use, it has been found that the moving blades on the blade holder need to be adjusted and installed. During installation, the moving blades are first temporarily and partially fixed with bolts. Then, the operator repeatedly taps them with a hammer to adjust their position until the moving blades are aligned with the fixed blades. Finally, the bolts are turned to fix the moving blades in their final position. However, this method is cumbersome, requires repeated use of tools and constant confirmation of the moving blades' position, and during this process, the moving blades may flare, making the use of the crushing tools inconvenient. Summary of the Invention

[0004] The technical problem this utility model aims to solve is that workers repeatedly tap the moving blade with a hammer to adjust its position until it matches the fixed blade position, and then rotate the bolt to finally fix the moving blade in place. However, this method is cumbersome, requires repeated use of tools and constant confirmation of the moving blade's position, and during this process, the moving blade may chip, leading to inconvenience in using the crushing tool.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a crushing tool, including a rotating shaft, a tool holder is installed on the arc surface of the rotating shaft, and moving blades are respectively installed around the triangle of the tool holder by means of bolts. An auxiliary device is provided on the surface of the tool holder on one side of the moving blades, wherein the auxiliary device pre-adjusts and fixes the installation position of the moving blades by means of a positioning plate and a screw.

[0006] The effect achieved by the above components is as follows: when the plastic crusher is installing and adjusting the blades, and the moving blade is installed on the blade holder on the rotating shaft, the moving blade is first placed in the assembly position of the blade holder, and the position of the blade holder is temporarily stabilized by bolts. Then, the auxiliary device is operated to adjust and move the moving blade to the appropriate installation position. Finally, the bolts on the moving blade are rotated to fix the moving blade in the final position.

[0007] Preferably, the auxiliary device includes a mounting plate mounted on the tool holder, a screw rotatably disposed on the surface of the mounting plate, a positioning plate threaded through the arc surface of the screw, and the positioning plate having a "U" shaped cross-section, stabilizing plates slidably disposed on the surface of the positioning plate on both sides of the screw, and a nut threadedly disposed on the arc surface of the screw, with the nut located between the positioning plate and the mounting plate.

[0008] The effect achieved by the above-mentioned components is that when installing and adjusting the moving blades of the plastic crusher, the position of the moving blades can be adjusted to the installation position more quickly and conveniently, without shaking or shifting, thus simplifying the installation process and improving the ease of use of the blades.

[0009] Preferably, the auxiliary device further includes an operating block installed at one end of the screw, the operating block assisting in the rotation of the screw.

[0010] The effect achieved by the above components is that the operation block makes the screw more convenient and faster to rotate, which in turn makes it more convenient and faster for the positioning plate to push the moving blade to change and adjust its position, thus improving the ease of use of the auxiliary device.

[0011] Preferably, the auxiliary device further includes reinforcing pads installed on both sides of the positioning plate surface, the reinforcing pads being rubber pads.

[0012] The effect achieved by the above components is that, by setting the reinforcing pad, gaps are less likely to occur when the positioning plate contacts and presses against the surface of the moving blade, thereby making the positioning plate more stable in pushing the moving blade to maintain stable adjustment and movement.

[0013] Preferably, the positioning plate has insertion holes on both sides of its surface, wherein the inner wall of the insertion hole is fitted with a plug installed on the moving blade surface.

[0014] The effect achieved by the above components is that, by setting the insert blocks, when the two sides of the positioning plate are pressed against the surface of the moving blade, the insertion holes on the positioning plate will be inserted into the insert blocks fixedly connected to the moving blade, thereby making the positioning plate and the moving blade more stable.

[0015] Preferably, a reinforcement device is provided on the surface of the tool holder at the position where the two moving tools are close to each other. The reinforcement device includes a mounting frame, which is fixedly connected to the surface of the tool holder. A connecting frame is inserted into the inner wall of the mounting frame, and one side of the connecting frame is telescopic. The two ends of the connecting frame are respectively inserted into the grooves on the surfaces of the two moving tools. The mounting frame and the connecting frame are fixedly connected by screws.

[0016] The aforementioned components achieve the following effects: the positions of the two moving blades on the same side of the blade holder are more stable, and the connectivity is further improved, thereby better crushing and processing of plastic materials and improving the performance of the crusher.

[0017] Preferably, the reinforcement device further includes locking blocks installed on both sides of the connecting frame surface, wherein the locking blocks engage with the locking grooves on the mounting frame surface.

[0018] The effect achieved by the above components is that the connection between the connecting frame and the mounting frame is further improved by the snap-fit ​​setting of the snap-fit ​​block and the snap-fit ​​slot, so that the position of the connecting frame is more stable and firm, thereby better ensuring the connection between the two moving blades.

[0019] Preferably, the crusher is adapted to a crushing tool.

These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] Figure 1 The crushing tool and crusher shown include a rotating shaft 1, a tool holder 2 mounted on the arc surface of the rotating shaft 1, movable blades 3 mounted around the triangular area of ​​the tool holder 2 by means of bolts, an auxiliary device 4 provided on the surface of the tool holder 2 on one side of the movable blades 3, wherein the auxiliary device 4 pre-adjusts and fixes the installation position of the movable blades 3 by means of a positioning plate 43 and a screw 42, and a reinforcing device 5 provided on the surface of the tool holder 2 at the position where the two movable blades 3 are close to each other.

[0031] Figure 1 , Figure 2 and Figure 3The auxiliary device 4 shown includes a mounting plate 41 mounted on the cutter holder 2. A screw 42 is rotatably mounted on the surface of the mounting plate 41. A positioning plate 43 is threaded through the arc surface of the screw 42, and the positioning plate 43 has a "U" shaped cross-section. Stabilizing plates 44 are slidably mounted on both sides of the screw 42 on the surface of the positioning plate 43. A nut 49 is threaded through the arc surface of the screw 42, and the nut 49 is located between the positioning plate 43 and the mounting plate 41. When the plastic crusher is installing and adjusting the cutters, and the moving cutter 3 is mounted on the cutter holder 2 on the rotating shaft 1, the moving cutter 3 is first placed in the assembly position of the cutter holder 2, and the cutter holder 2 is temporarily stabilized by bolts. Then, the screw 42 is rotated, causing the mounting plate 41, which is fixedly connected to the cutter holder 2, to rotate. The positioning plate 43 is fixedly connected to the two stabilizing plates 44 on the blade holder 2 to limit its position. Therefore, under the rotation of the screw 42, the positioning plate 43 moves closer to the position of the moving blade 3 until both ends of the positioning plate 43 contact and press against the surface of the moving blade 3, pushing the moving blade 3 closer to the fixed blade on the side of the crushing frame until the gap between the two is suitable for use. Then, the nut 49 on the screw 42 is rotated so that the nut 49 contacts and presses against the mounting plate 41 to ensure the position of the screw 42 is stable. Then, the bolt on the moving blade 3 is rotated to finally fix and limit the position of the moving blade 3. At this time, when the plastic crusher is installing and adjusting the moving blade 3, the position of the moving blade 3 can be adjusted to the installation position more quickly and conveniently, and it is not easy to shake or shift, thus simplifying the installation method and improving the convenience of using the blade.

[0032] Figure 1 , Figure 2 and Figure 3 The auxiliary device 4 shown also includes an operating block installed at one end of the screw 42. The operating block assists in the rotation of the screw 42. The operation block makes it easier and faster for the screw 42 to rotate, which in turn makes it easier and faster for the positioning plate 43 to push the moving blade 3 to change its position. This improves the ease of use of the auxiliary device 4. The auxiliary device 4 also includes reinforcing pads 45 installed on both sides of the surface of the positioning plate 43. The reinforcing pads 45 are rubber pads. The reinforcing pads 45 ensure that the positioning plate 43 is in contact with the surface of the moving blade 3. During compression, gaps are less likely to form, thus allowing the positioning plate 43 to more stably push the moving blade 3 to maintain stable adjustment and movement. The positioning plate 43 has insertion holes 47 on both sides of its surface. Insertion blocks 48 installed on the surface of the moving blade 3 are inserted into the inner wall of the insertion holes 47. With the insertion blocks 48, when the two sides of the positioning plate 43 are pressed against the surface of the moving blade 3, the insertion holes 47 on the positioning plate 43 will be inserted into the insertion blocks 48 fixedly connected to the moving blade 3, thereby better maintaining stability between the positioning plate 43 and the moving blade 3.

[0033] Figure 1 and Figure 4The reinforcement device 5 shown includes a mounting frame 51, which is fixedly connected to the surface of the blade holder 2. A connecting frame 52 is inserted into the inner wall of the mounting frame 51, and one side of the connecting frame 52 is telescopic. The two ends of the connecting frame 52 are respectively inserted into the grooves on the surfaces of the two moving blades 3. The mounting frame 51 and the connecting frame 52 are connected and fixed by screws 53. When the two blade holders 2 on the same side of the surface of the blade holder 2 are installed, the connecting frame 52 is first inserted into the mounting frame 51 fixedly connected to the surface of the blade holder 2. At this time, the two ends of the connecting frame 52 are respectively inserted into the grooves at the positions of the two moving blades 3 that are close to each other. Then, the screws 53 penetrate the surface of the mounting frame 51 and are threadedly connected to the connecting frame 52, so that the positions of the connecting frame 52 and the mounting frame 51 are fixed. At this time, the positions of the two moving blades 3 on the same side of the blade holder 2 are more stable, the connection is further improved, and thus the plastic materials are better crushed and processed, improving the use effect of the crusher.

[0034] Figure 1 and Figure 4 The reinforcement device 5 shown also includes locking blocks 54 installed on both sides of the surface of the connecting frame 52. The locking blocks 54 engage with the slots 55 on the surface of the mounting frame 51. Through the engagement of the locking blocks 54 and the slots 55, the connection between the connecting frame 52 and the mounting frame 51 is further improved, thereby making the position of the connecting frame 52 more stable and firm, thus better ensuring the connection between the two moving blades 3.

[0035] Working principle: When the plastic crusher is installing and adjusting the blades, and the moving blade 3 is installed on the blade holder 2 on the rotating shaft 1, the moving blade 3 is first placed in the assembly position of the blade holder 2, and the position of the blade holder 2 is temporarily stabilized by bolts. Then, the screw 42 is rotated, causing the screw 42 to rotate on the surface of the mounting plate 41 fixedly connected to the blade holder 2. Because the positioning plate 43 is limited in position by the two stabilizing plates 44 fixedly connected to the blade holder 2, the positioning plate 43 moves closer to the position of the moving blade 3 under the rotation of the screw 42 until both ends of the positioning plate 43 contact and compress. On the surface of the moving blade 3, push the moving blade 3 closer to the fixed blade on the side of the crushing frame until the gap between the two is suitable for use. Then rotate the nut 49 on the screw 42 so that the nut 49 contacts and presses against the mounting plate 41 to ensure the position of the screw 42 is stable. Then rotate the bolt on the moving blade 3 to finally fix and limit the position of the moving blade 3. At this time, when the plastic crusher is installing and adjusting the moving blade 3, the position of the moving blade 3 can be adjusted to the installation position more quickly and conveniently and smoothly, without shaking or displacement, thus simplifying the installation method and improving the convenience of using the blade.

[0036] When two blade holders 2 on the same side of the blade holder 2 are installed, first insert the connecting bracket 52 into the mounting frame 51 that is fixedly connected to the surface of the blade holder 2. At this time, the two ends of the connecting bracket 52 are respectively inserted into the grooves of the two moving blades 3 that are close to each other. Then, the screw 53 passes through the surface of the mounting frame 51 and is threadedly connected to the connecting bracket 52, so that the positions of the connecting bracket 52 and the mounting frame 51 are fixed. At this time, the positions of the two moving blades 3 on the same side of the blade holder 2 are more stable, and the connection is further improved, thereby better crushing and processing of plastic materials and improving the use effect of the crusher.

[0037] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
