[0021] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0022] Example 1

[0023] Reference Figures 1-4 This embodiment proposes a grinding device for producing plastic foam board molds. By setting up the connecting device 2, the problem of the grinding efficiency of plastic foam board caused by the long time required to install the grinding plate is solved. The device includes a processing table 1, a support frame 11 fixedly installed on the processing table 1, a fixed column 12 fixedly installed on the support frame 11, a rotating block 13 rotatably installed on the fixed column 12, a motor 6 fixedly installed inside the fixed column 12, and the output end of the motor 6 passes through the fixed column 12 and is fixedly connected to the rotating block 13. The rotating block 13 is rotated by starting the motor 6. A grinding disc 7 is fixedly installed on the insert block 23. Two sets of symmetrical handles 8 are rotatably installed on the grinding disc 7. A torsion spring is sleeved on the connecting shaft of the handle 8 so that the handle 8 can be quickly reset. By rotating the two handles 8 and holding them, it is convenient to operate the grinding disc 7. The connecting device 2 is installed inside the rotating block 13, which makes the installation of the grinding disc 7 more convenient.

[0024] The connecting device 2 includes a slot 21 formed on the rotating block 13. The slot 21 has two symmetrical sets of beveled grooves 22. A plug block 23 is inserted into the slot 21. The plug block 23 has two symmetrical sets of recesses 24. Two symmetrical sets of first-order fixing rods 25 are fixedly installed in each set of recesses 24, making the movement of the connecting block 26 more stable. A connecting block 26, which cooperates with the beveled grooves 22, is slidably mounted on the first-order fixing rod 25. The connecting block 26 has beveled edges, and a first-order spring 27 is installed in each set of recesses 24. This allows the connecting block 26 to quickly reset. When installing the grinding disc 7, the insert block 23 is aligned with the slot 21 and inserted. When the connecting block 26 is inserted into the slot 21, it is pressed into the groove 24 by the outer wall of the slot 21. When the connecting block 26 corresponds to the position of the beveled groove 22, the connecting block 26 is moved out of the groove 24 and into the beveled groove 22 under the action of the first spring 27, thereby completing the installation of the grinding disc 7. This avoids the situation where it takes a lot of time to install the grinding disc, which affects the grinding efficiency of the plastic foam board.

[0025] A fixed ring 3 is fixedly installed on the rotating block 13 and slidably connected to the fixed column 12, which makes the rotating block 13 rotate more stably within the fixed column 12. A support ring 31 is slidably installed on the fixed column 12. An annular groove 32 is opened on the support ring 31. Two sets of symmetrical arc blocks 33 are slidably installed in the annular groove 32. When the rotating block 13 rotates, it does not need to drive the electric telescopic rod 44 to rotate together. This not only makes the rotation of the rotating block 13 more stable, but also extends the service life of the motor 6 and the electric telescopic rod 44.

[0026] Example 2

[0027] Based on Example 1, the technical solution proposed in Example 1 is used to solve the disadvantage that the installation of the grinding plate requires a lot of time, which affects the grinding efficiency of the plastic foam board. The disassembly of the grinding plate is also relatively complicated.

[0028] Reference Figures 1-4A disassembly device 4 is installed on the rotating block 13. The disassembly device 4 includes a sliding frame 41 that is slidably installed on the rotating block 13 and fixedly connected to the support ring 31. Two sets of symmetrical slots 42 communicating with the slot 21 are opened on the rotating block 13. A second fixing rod 43 that is slidably connected to the sliding frame 41 is fixedly installed on each set of slots 42. Two sets of symmetrical electric telescopic rods 44 are fixedly installed on the fixing column 12, and the movable end of the electric telescopic rod 44 is fixedly connected to the arc block 33. A limit groove 5 is opened on the rotating block 13. A limit block 51 is slidably installed in the limit groove 5. Two sets of symmetrical third fixing rods 52 that are slidably connected to the limit block 51 are fixedly installed in the limit groove 5. A second spring 53 is installed in the limit groove 5 to limit the movement of the rods. Block 51 can quickly reset. When the insert 23 is inserted into the slot 21, the insert 23 pushes the limiting block 51 into the limiting groove 5. The second spring 53 is compressed by the force, which makes the limiting block 51 squeeze the insert 23, thus limiting the insertion 23 and making the connection between the insert 23 and the rotating block 13 more secure. When it is necessary to disassemble the grinding disc 7, the electric telescopic rod 44 is activated to drive the support ring 31 connected to the arc block 33 to move. The support ring 31 drives the sliding frame 41 to move in the rotating block 13. The sliding frame 41 presses the connecting block 26 into the groove 24. Under the action of the second spring 53, the insert 23 in the slot 21 is popped out by the limiting block 51, thus completing the quick disassembly of the grinding disc 7, which is convenient for the replacement and maintenance of the grinding disc 7.
