[0015] 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.

[0016] This utility model provides, for example Figure 1-3 The image shows a plastic pelletizing and pelletizing device.

[0017] Example 1: Includes a pelletizer housing 1, mounting shafts 2, a drive assembly, and a mounting assembly 4. The mounting shafts 2 are located inside the pelletizer housing 1, and pelletizing blades are mounted on the outer wall of the mounting shafts 2. The drive assembly is located on the pelletizer housing 1 and is used to drive the mounting shafts 2 to rotate. The pelletizer housing 1 is provided with a feed inlet and a discharge outlet. Thus, the drive assembly drives the two mounting shafts 2 to rotate in opposite directions, which allows the pelletizing blades outside the mounting shafts 2 to pelletize long strips of plastic. This is existing technology and will not be described in detail here. The mounting assemblies 4 are symmetrically arranged on the pelletizer housing 1 and are used to limit the installation of the mounting shafts 2. Under the action of the mounting assemblies 4, the mounting shafts 2 can be easily installed or removed.

[0018] Furthermore, the mounting assembly 4 includes a fixed housing 41 and an integrated bracket 44. The bottom of the outer wall of the fixed housing 41 is fixedly connected to the pelletizer housing 1. A slot matching the mounting shaft 2 is provided on the top of one side of the fixed housing 41. The mounting shaft 2 can be connected to or separated from the fixed housing 41 through the slot. The integrated bracket 44 is disposed inside the fixed housing 41. The integrated bracket 44 is used to connect and install the mounting shaft 2. The integrated bracket 44 can ensure the stability of the installation of the two mounting shafts 2.

[0019] Furthermore, the mounting assembly 4 also includes a mounting housing 42, a protective housing 43, a fastener 45, and a fixing bolt 46. The mounting housing 42 is fixedly mounted on the top of the fixed housing 41 and is used to limit the connection of the integrated bracket 44, thereby ensuring the stability of the integrated bracket 44 in the installation of the mounting shaft 2. The end of the protective housing 43 is fixedly connected to the mounting housing 42 and is used to shield and protect the pelletizing blade. The fastener 45 is fixedly connected to the side of the fixed housing 41, and the fixing bolt 46 is located on one side of the fastener 45. The outer wall of the fixing bolt 46 is threadedly connected to the mounting housing 42. By removing the fixing bolt 46, the mounting housing 42 and the protective housing 43 can be removed, and then the mounting shaft 2 can be removed using the integrated bracket 44.

[0020] Furthermore, the drive assembly includes a first gear 31, a drive motor 32, and a second gear 33. The first gear 31 is fixedly installed on the outside of the mounting shaft 2, and adjacent first gears 31 are meshed together. The drive motor 32 is installed on one side of the pelletizer housing 1, and the second gear 33 is driven and installed at the output end of the drive motor 32. The second gear 33 is meshed with one of the first gears 31, and the second gear 33 is located at the bottom of the first gear 31. This facilitates the connection or separation of the first gear 31 and the second gear 33 at the end of the mounting shaft 2 when the mounting shaft 2 is installed or disassembled.

[0021] Example 2: Based on Example 1, the integrated bracket 44 includes a mounting plate 441, an arc plate 442, and a connecting rod 443. The side of the mounting plate 441 is in contact with the fixed housing 41 and the mounting housing 42. The arc plate 442 is fixedly connected to one side of the mounting plate 441, and the arc plate 442 is symmetrically rotated and sleeved on the outside of the mounting shaft 2, as shown. Figure 2 and Figure 3 As shown, when the two mounting plates 441 are installed between the fixed housing 41 and the mounting housing 42, the arc plate 442 on the opposite side of the two mounting plates 441 can be stably sleeved on the outside of the mounting shaft 2, thereby limiting the installation of the mounting shaft 2. The connecting rod 443 is fixedly connected to one side of one of the arc plates 442, and the other arc plate 442 has a connecting groove that matches the connecting rod 443 on one side. The connecting rod 443 is engaged with the connecting groove, which can ensure the stability of the connection between the two arc plates 442 on the outside of the mounting shaft 2.

[0022] Furthermore, the integrated bracket 44 also includes a snap-fit ​​member 444, a connecting sleeve 445, and a connecting post 446. The snap-fit ​​member 444 is fixedly connected to the inside of the fixed housing 41. The bottom of the mounting plate 441 is slidably snapped into the snap-fit ​​member 444. Under the action of the snap-fit ​​member 444, the stability of the mounting plate 441 inside the fixed housing 41 can be guaranteed. The end of the connecting sleeve 445 is in contact with the mounting plate 441. One end of the connecting post 446 is fixedly connected to the mounting plate 441. The outer wall of the connecting post 446 is slidably sleeved with the connecting sleeve 445. The connecting sleeve 445 can guarantee the stability of the top of the mounting plate 441 inside the mounting housing 42. When disassembling the mounting housing 42, the mounting plate 441 can be lifted out using the connecting sleeve 445, and the mounting shaft 2 can be taken out through the arc plate 442, thereby completing the disassembly of the mounting shaft 2.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
