[0020] 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 a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0021] Please see Figures 1-3 This utility model discloses a pelletizing component for a pelletizer, including a roller wheel 1. The outer wall of the roller wheel 1 has several mounting grooves arranged in a ring. A slider 14 is installed at each mounting groove of the roller wheel 1, and a blade 2 is slidably inserted on each corresponding slider 14. The blade 2 is used to cooperate with the roller wheel 1 to pelletize the strip material of the pelletizer.

[0022] In one embodiment, the device further includes a limiting component, which includes a first limiting ring 3 and a second limiting ring 4 disposed on both sides of the hobbing wheel 1. The second limiting ring 4 is used to block one side of each blade 2. The first limiting ring 3 can rotate back and forth around the center of the hobbing wheel 1. After rotating, it can limit the other side of each blade 2 or release the limitation on the other side of each blade 2.

[0023] In practice, during operation, the first limiting ring 3 and the second limiting ring 4 respectively block both sides of the blade 2, causing the blade 2, which is slidably inserted on the slider 14, to be in a limited state. In this state, the strip material can be granulated. When maintenance or replacement is required, the roller wheel 1 is removed from the granulator, and then the first limiting ring 3 can be rotated to release the limitation on the blade 2. At this time, each blade 2 can slide towards the side closer to the first limiting ring 3 in the axial direction of the roller wheel 1. When it slides to the point of separation from the slider 14, the blade 2 can be maintained or replaced. During installation, it is only necessary to reverse the above steps. This device has a simple structure and is easy to replace, which is convenient for practical use.

[0024] In one embodiment, the hobbing wheel 1 includes a wheel body 11, on which a plurality of arc-shaped guide grooves 13 are provided and distributed in a ring around the center of the wheel body 11. Each slider 14 is mounted on the wheel body 11. The first limiting ring 3 includes a ring body 31, a plurality of take-out grooves 32 provided on the edge of the ring body 31, and a pin 34 mounted on the ring body 31. The pin 34 is inserted into the guide groove 13.

[0025] In specific implementation, when the ring body 31 rotates, the pin 34 can move from one side to the other side in the guide groove 13. When the pin 34 is located on one side or the other side of the guide groove 13, the ring body 31 can rotate until each extraction groove 32 is aligned with or misaligned with the corresponding blade 2. When the extraction groove 32 is aligned with the corresponding blade 2, the blade 2 can slide through the extraction groove 32 until it separates from the slider 14. When the extraction groove 32 is misaligned with the corresponding blade 2, the ring body 31 will block each blade 2, thereby cooperating with the second limiting ring 4 to limit the blade 2 inserted on each slider 14.

[0026] In one embodiment, the wheel body 11 has at least two screw holes 12 for bolt installation, and the ring body 31 has locking holes 33 corresponding to the screw holes 12. When the ring body 31 is rotated to the point that each take-out groove 32 is not aligned with the corresponding blade 2, the screw holes 12 and the locking holes 33 are aligned.

[0027] With this design, when the ring body 31 cooperates with the second limiting ring 4 to limit the blade 2 inserted on each slider 14, the ring body 31 and the wheel body 11 can be fixed by installing a bolt through the locking hole 33 at the screw hole 12, and the second limiting ring 4 can also be fixed to the side of the wheel body 11 away from the ring body 31 by bolts.

[0028] In one embodiment, the blade 2 includes a blade body 21 and a slot 22 formed on the blade body 21. The slider 14 is T-shaped and can be inserted into the corresponding slot 22 of the blade body 21.

[0029] This design ensures that the blade 2 is inserted into the slider 14 and is very stable when both sides are blocked by the first limiting ring 3 and the second limiting ring 4, which facilitates practical use.

[0030] In one embodiment, the edges of the slider 14 are rounded.

[0031] With this design, when the blade 2 needs to be installed on the slider 14, the edges of the slider 14 are rounded, which reduces the occurrence of jamming during installation. Therefore, the installation efficiency of the blade 2 can be increased without affecting the stability of the structure.

[0032] It should be noted that if the embodiments of this utility model involve directional indicators such as up, down, left, right, front, back, etc., the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicators will also change accordingly.

[0033] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features.
