[0020] This utility model provides an easy-to-install cutting tool for a plastic crusher, including a body 101, a motor 102, an installation and disassembly mechanism, and multiple blades 108. The installation and disassembly mechanism includes an assembly assembly, a drive shaft 103, an installation shaft 104, multiple installation cylinders 105, multiple limiting assemblies, and a fixing assembly. The limiting assembly includes fastening bolts 116 and fastening nuts 117. The installation cylinder 105 has two through holes 106, and the installation shaft 104 has multiple positioning holes 107. The fixing assembly includes a threaded post 109 and a fixing nut 110. The assembly assembly includes a threaded rod 113, a fixing cylinder 112, a partition 118, a load-bearing seat 115, and a fixing post 111. The fixing cylinder 112 has a fixing groove 114. The aforementioned solution solves the problem that after long-term operation, the cutting tool of a plastic crusher is likely to be damaged and needs to be replaced. However, in the prior art, the cutting tool of this device is not easy to install and disassemble. If one blade 108 of the cutting tool is damaged, the entire cutting tool needs to be replaced, which increases the maintenance cost of the device.

[0021] In this embodiment, the motor 102 is disposed on the outer side wall of the body 101. The drive shaft 103 is fixedly connected to the output end of the motor 102 and extends into the body 101. The mounting shaft 104 is fixedly connected to one end of the drive shaft 103. A plurality of mounting cylinders 105 are slidably connected to the mounting shaft 104. A plurality of blades 108 are respectively fixedly connected to both ends of the plurality of mounting cylinders 105. A plurality of limiting components are disposed on the plurality of mounting cylinders 105 and the mounting shaft 104. A fixing component is disposed at the end of the mounting shaft 104 away from the drive shaft 103. When one of the blades 108 of the device is damaged, the fixing component moves the mounting shaft 104 away from the drive shaft 103. One end of the shaft 103 is opened, and the mounting cylinder 105 is disassembled sequentially through multiple limiting components. The mounting cylinder 105 is then pulled away from the mounting shaft 104 until the operator removes the damaged blade 108. After the operator replaces the damaged blade 108, the mounting cylinder 105 is installed back onto the mounting shaft 104. The through hole 106 on the mounting cylinder 105 is aligned with the positioning hole 107 on the mounting shaft 104. The mounting cylinder 105 is then fixed to the mounting shaft 104 through the limiting components. The multiple blades 108 of this plastic crusher can be easily installed and disassembled, and any one of the blades 108 can be disassembled and repaired, thereby reducing the maintenance cost of the device.

[0022] Furthermore, the fastening bolt 116 is threadedly connected to the mounting sleeve 105 and the mounting shaft 104, and the fastening bolt 116 is located in the through hole 106 and the positioning hole 107. The fastening nut 117 is threadedly connected to the fastening bolt 116, and the mounting sleeve 105 and the mounting shaft 104 are located between the fastening bolt 116 and the fastening nut 117.

[0023] In this embodiment, the mounting cylinder 105 is mounted onto the mounting shaft 104 by two fastening bolts 116 and two fastening nuts 117, ensuring that the blade 108 located on the mounting cylinder 105 remains stable when the device is in operation.

[0024] Furthermore, the threaded post 109 is fixedly connected to the end of the mounting shaft 104 away from the drive shaft 103, and the fixing nut 110 is threadedly connected to the threaded post 109.

[0025] In this embodiment, the fixing nut 110 fixes the plurality of mounting cylinders 105 between the threaded post 109 and the drive shaft 103, ensuring that the mounting cylinders 105 will not slip off the mounting shaft 104.

[0026] Furthermore, the assembly component is located at one end of the body 101 away from the drive shaft 103.

[0027] Furthermore, the threaded rod 113 is threadedly connected to one end of the machine body 101 away from the drive shaft 103, the fixed cylinder 112 is rotatably connected to one end of the threaded rod 113 and located inside the machine body 101, the fixed column 111 is fixedly connected to one end of the threaded column 109 away from the mounting shaft 104, and the fixed cylinder 112 is slidably connected to the fixed column 111.

[0028] Furthermore, the partition 118 is fixedly connected to the body 101, the fixed cylinder 112 is slidably connected to the partition 118 and passes through the partition 118, and the load-bearing seat 115 is fixedly connected to the partition 118 and is located below the fixed cylinder 112.

[0029] In this embodiment, after the blade 108 is installed, the threaded rod 113 is rotated, and the threaded rod 113 drives the fixed cylinder 112 to move towards the fixed post 111 until the fixed post 111 is fully inserted into the fixed groove 114. When the device is working, the motor 102 drives the drive shaft 103 and the multiple blades 108 to rotate, and the fixed cylinder 112 rotates synchronously with the drive shaft 103. The load-bearing seat 115 on the partition 118 provides support for the fixed cylinder 112 and the components on the mounting shaft 104.

[0030] When replacing or repairing the blade 108 using this invention, rotate the threaded rod 113 to move the fixed cylinder 112 away from the fixed post 111. The fixed cylinder 112 then moves away from the fixed post 111. Rotate the fixing nut 110 to open the end of the mounting shaft 104 away from the drive shaft 103. The operator can then disassemble the mounting cylinder 105 using the two fastening bolts 116 and two fastening nuts 117, and disassemble the mounting cylinder 105 between the threaded post 109 and the damaged blade 108, making it easier for the operator to remove the damaged blade. The blade 108 is disassembled, and the operator replaces the damaged blade 108. Then, the mounting cylinder 105 is installed on the mounting shaft 104, and the through hole 106 on the mounting cylinder 105 is aligned with the positioning hole 107 on the mounting shaft 104. The mounting cylinder 105 is then fixed to the mounting shaft 104 by two fastening bolts 116 and two fastening nuts 117. The multiple blades 108 of the plastic crusher can be easily installed and disassembled, and any one of the blades 108 can be disassembled and repaired, thereby reducing the maintenance cost of the device.
