[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0029] Example 1

[0030] Reference Figures 1-6 This is the first embodiment of the present invention. This embodiment provides a die head assembly for a water ring granulation device. The bearing dust protection device for power tools includes a main body assembly 100 and an adjustment assembly 200. The two work together to allow for quick assembly and disassembly of the die head and fine adjustment of the distance between the die head and the blade.

[0031] Specifically, the main component 100 includes a feeding pipe 101, one end of which is connected to a die head 102, and the inner wall of the die head 102 is provided with multiple limiting grooves 102-1.

[0032] Once the water ring granulation device has completed its initial preparations, the feeding system begins operation. The material is pushed into the feeding pipe 101 by the conveying equipment and then transported to the die head 102. The internal structure of the die head 102 is designed to ensure that the material is evenly distributed inside, ensuring that the amount and flow rate of material extruded from each orifice are consistent. After being extruded from the die head 102, the material enters the subsequent granulation process. A blade is usually provided on one side of the die head 102, which is mainly used to cut the material extruded from the die head 102 into particles of a specific length.

[0033] Specifically, the adjustment component 200 is located at one end of the mold head 102 and includes an adjustment element 201, including a gear ring 201a. One end of the gear ring 201a is meshed with a gear 201b, and one end of the gear 201b is meshed with a rack 201c. One end of the rack 201c is fixed with a retaining strip 201d, and one end of the gear ring 201a is fixed with a moving plate 201e. A limit strip 201f is provided on one side of the moving plate 201e, and the other end of the limit strip 201f is located on the inner wall of the limit groove 102-1.

[0034] There are six gears 201b and six racks 201c, and the gear ring 201a is rotatably connected to the first fixed frame 202b.

[0035] When the die head 102 needs to be adjusted, the limiting strip 201f is moved to separate it from the limiting groove 102-1. Then, the moving plate 201e is moved, which drives the gear ring 201a to rotate. The gear ring 201a rotates and meshes with the gear 201b, causing it to rotate. The rotation of the gear 201b meshes with the rack 201c, causing it to move. When the rack 201c moves, it drives the locking strip 201d to move. The movement of the locking strip 201d allows it to engage with the feed pipe 101, thus quickly completing the installation of both.

[0036] When the die head 102 needs to be installed, the limiting strip 201f is moved first to separate it from the limiting groove 102-1. Then the moving plate 201e is moved. The movement of the moving plate 201e drives the gear ring 201a to rotate. The rotation of the gear ring 201a meshes with the six gears 201b to make it rotate. The simultaneous rotation of the gears 201b will mesh with the six racks 201c to make them move. The movement of the racks 201c drives the locking strip 201d to move. The movement of the locking strip 201d can make it engage with the feed pipe 101.

[0037] Example 2

[0038] Reference Figures 1-6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0039] Specifically, the adjustment assembly 200 also includes a fixing member 202, which includes a fixing rod 202a inserted into the inner wall of the gear 201b, and the other end of the fixing rod 202a is fixed to one end of the mold head 102.

[0040] The fixed rod 202a is movably connected to the gear 201b and is used to support the gear 201b.

[0041] Specifically, each of the card strips 201d is fitted with a first fixing frame 202b on its outer side. The other end of the first fixing frame 202b is fixed to one end of the mold head 102. Each of the first fixing frames 202b has a fixing groove 202b-1 on its inner wall. The rack 201c slides on the inner wall of the fixing groove 202b-1.

[0042] The first fixing frame 202b is used to support the card strip 201d and the rack 201c. By moving the rack 201c, the rack 201c will slide stably in the fixing groove 202b-1.

[0043] Specifically, a second fixing frame 202c is also sleeved on the outside of the card strip 201d. A support groove 202c-1 is opened on the inner wall of the second fixing frame 202c. The rack 201c slides on the inner wall of the support groove 202c-1.

[0044] The second fixing bracket 202c is used to further support the clip 201d and the rack 201c. The rack 201c and the clip 201d can slide stably on the inner wall of the support groove 202c-1 by moving, making them more stable when moving.

[0045] Specifically, a protective disc 202d is provided at one end of the fixing rod 202a.

[0046] The protective disc 202d is used to protect the gear 201b and prevent it from falling off during rotation.

[0047] Specifically, a support frame 202e is fitted on the outer side of the rack 201c, and a locking groove 202e-1 is opened on the inner wall of the support frame 202e. The other end of the support frame 202e is fixed to the inner wall of the feed pipe 101.

[0048] There are three support frames 202e, and each support frame 202e has six locking grooves 202e-1 on its inner wall.

[0049] By moving the card strip 201d to engage with the engagement slots 202e-1 at different positions, the mold head 102 can be finely adjusted.

[0050] The die head 102 can be installed at different distances from the blade. By fine-tuning, the die head 102 can be positioned at a suitable level, allowing the particles to cool at an appropriate rate after extrusion. Different distances between the die head 102 and the blade will change the flight distance of the particles from the extruded particles to the cooling water. Increasing the distance prolongs the exposure time of the particles in the air, increases heat dissipation, and lowers the temperature when entering the cooling water, resulting in a more gradual cooling rate. Decreasing the distance allows the particles to enter the cooling water faster, resulting in a faster cooling rate, but may lead to a large temperature difference between the surface and the interior of the particles. When fine-tuning of the die head 102 is required, it is adjusted by the amount of material fed in by the operator.

[0051] When the position of the die head 102 needs to be finely adjusted according to the size of the material and the required cooling rate, the die head 102 is placed in the feed pipe 101 at the desired installation position. The limiting strip 201f is moved to separate from the limiting groove 102-1. Then, the moving plate 201e is moved, which drives the gear ring 201a to rotate. The rotating gear ring 201a meshes with the gear 201b to rotate. The rotating gear 201b meshes with the rack 201c to move. When the rack 201c moves, it drives the locking strip 201d to move. By moving the locking strip 201d to the inner wall of the locking groove 202e-1, the installation of the die head 102 at different positions is completed.

[0052] When the position of the die head 102 needs to be finely adjusted according to the size of the material and the required cooling rate, the limiting strip 201f is moved to separate from the limiting groove 102-1. Then, the moving plate 201e is moved, which drives the gear ring 201a to rotate. The rotation of the gear ring 201a meshes with the gear 201b, causing it to rotate. The rotation of the gear 201b then meshes with the rack 201c, causing it to move. When the rack 201c moves, it will drive the locking strip 201d to move. When the rack 201c and the locking strip 201d move, they will slide on the inner walls of the fixed groove 202b-1 and the support groove 202c-1. By moving the rack 201c and the locking strip 201d to engage with the inner wall of the engaging groove 202e-1, the adjustment of the mold head 102 at different positions is completed. Then, the limiting strip 201f is released so that it re-engages with the limiting groove 102-1, thereby completing the limiting.

[0053] When it is necessary to remove the mold head 102, the limiting strip 201f is separated from the limiting groove 102-1, and then the gear ring 201a is reversed to return it to its original position. The rotation of the gear ring 201a can drive the rack 201c and the locking strip 201d to move. The movement of the two can separate them from the locking groove 202e-1, thereby completing the adjustment of different positions of the mold head 102 and quick assembly and disassembly.

[0054] Example 3

[0055] Reference Figures 5-6 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0056] Specifically, the adjustment component 200 also includes a limiting member 203, which includes a connecting strip 203a sleeved on the outside of the limiting strip 201f, and a pressing strip 203b is provided at one end of the connecting strip 203a.

[0057] By pressing the pressing strip 203b, the pressing strip 203b moves and drives the connecting strip 203a to move. The movement of the connecting strip 203a can cause the limiting strip 201f to separate from the limiting groove 102-1, thereby allowing the moving plate 201e to move.

[0058] Specifically, a support shaft 203c is inserted into the inner wall of the pressing strip 203b, and both ends of the support shaft 203c are inserted into the inner wall of the movable plate 201e for rotation.

[0059] The support shaft 203c is used to support the pressing strip 203b. The movement of the pressing strip 203b can drive the support shaft 203c to rotate on the inner wall of the moving plate 201e.

[0060] Specifically, a spring 203d is provided at one end of the limiting strip 201f, and the other end of the spring 203d is fixed to the inner wall of the moving plate 201e.

[0061] By pressing the pressing strip 203b, the pressing strip 203b moves, causing the connecting strip 203a to move. The moving connecting strip 203a presses the spring 203d. At this time, the limiting strip 201f will separate from the limiting groove 102-1. Then, the moving plate 201e moves to adjust the mold head 102. After the adjustment is completed, by releasing the movement of the pressing strip 203b, the spring 203d will rebound, allowing the limiting strip 201f to re-engage with the limiting groove 102-1.

[0062] Specifically, a handle 203e is provided at one end of the pressing strip 203b.

[0063] By moving the handle 203e, the pressing strip 203b can be moved.

[0064] In use, when fine-tuning the position of the die head 102 is required, the die head 102 is placed in the feed pipe 101 at the desired installation position. Moving the handle 203e moves the pressing bar 203b, which in turn moves the connecting bar 203a. The connecting bar 203a then compresses the spring 203d, causing the limiting bar 201f to separate from the limiting groove 102-1. Then, moving the moving plate 201e causes the gear ring 201a to rotate, meshing with the gear 201b. When gear 201b rotates, it meshes with rack 201c, causing it to move. As rack 201c moves, it drives clip 201d to move. When rack 201c and clip 201d move, they slide on the inner walls of fixed groove 202b-1 and support groove 202c-1. By moving rack 201c and clip 201d to engage with the inner wall of engagement groove 202e-1, the adjustment of different positions of mold head 102 is completed. Then, the limiting strip 201f is released. At this time, the spring 203d rebounds and drives the limiting strip 201f to re-engage with the limiting groove 102-1, thus completing the limiting.

[0065] When it is necessary to remove the mold head 102, the limiting strip 201f is separated from the limiting groove 102-1, and then the gear ring 201a is reversed to return it to its original position. The rotation of the gear ring 201a can drive the rack 201c and the locking strip 201d to move. The movement of the two can separate them from the locking groove 202e-1, thereby completing the adjustment of different positions of the mold head 102 and quick assembly and disassembly.

[0066] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
