Description

Technical Field

[0001] This utility model relates to the field of granulation equipment, and in particular to a granulation equipment for processing thermosetting plastics. Background Technology

[0002] A granulator is a device used to process raw materials from industries such as plastics, chemicals, and agriculture into granules. It plays an important role in the manufacturing, recycling, and reuse of plastics, and can transform powdered or lumpy raw materials into uniform, easily processed granules.

[0003] A pellet mill typically consists of a screw extruder, a cooling system, and a cutting and forming machine. The pellet raw material is hot-melted and extruded through the screw extruder, and extruded into a long strip shape under the action of the discharge head at the head of the screw extruder, and then cooled and shaped by the cooling system.

[0004] The discharge head of a screw extruder is usually fixed by a flange plate and bolts. However, using bolts to directly fix the flange plate requires tools to install and remove the discharge head, which may take a long time. Furthermore, during long-term use, the bolts may loosen due to vibration or thermal expansion, leading to melt leakage and material waste, thus posing certain defects. Utility Model Content

[0005] The purpose of this invention is to provide a granulation device for processing thermosetting plastics to solve the problems mentioned in the background art.

[0035] 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.

[0036] This utility model provides, for example Figure 1-4 The apparatus shown is a granulation device for processing thermosetting plastics.

[0037] Example 1

[0038] The device includes a screw extruder 1, a discharge head 2, a first flange plate 3, a second flange plate 4, and a locking assembly 5. The discharge head 2 is fitted onto the outside of the discharge end of the screw extruder 1, and a high-temperature resistant sealing material is provided between the discharge head 2 and the discharge end of the screw extruder 1 to ensure their sealing performance. The first flange plate 3 is fixedly fitted onto the outside of the discharge end of the screw extruder 1, and the second flange plate 4 is fixedly fitted onto the outside of the discharge head 2. The locking assembly 5 is arranged in a ring array on the outside of the first flange plate 3 and the second flange plate 4. The locking assembly 5 is used to lock the first flange plate 3 and the second flange plate 4. By disassembling the locking assembly 5, the first flange plate 3 and the second flange plate 4 can be separated, thereby allowing the discharge head 2 to be disassembled and maintained.

[0039] In particular, the locking assembly 5 includes a fixing rod 51, a snap-fit ​​frame 52, a limiting assembly 53, an annular groove 54, and a slot 55. One end of the fixing rod 51 is fixedly connected to the first flange plate 3, and the outer wall of the fixing rod 51 is slidably inserted into the second flange plate 4. The snap-fit ​​frame 52 is slidably snapped onto the outside of the first flange plate 3 and the second flange plate 4, and the snap-fit ​​frame 52 is snapped onto one end of the outer wall of the fixing rod 51. Thus, the snap-fit ​​frame 52 can not only snap-fit ​​and lock the first flange plate 3 and the second flange plate 4, but also, by snapping onto the outside of the fixing rod 51, can again lock the first flange plate 3 and the second flange plate 4. The first flange plate 3 and the second flange plate 4 are snapped together and locked. The limiting component 53 is disposed inside the snap-fit ​​frame 52 and snaps onto the outside of the fixing rod 51. The annular groove 54 is opened on the outside of the fixing rod 51. The limiting component 53 corresponds to the annular groove 54. The slot 55 is opened on one side of the bottom of the snap-fit ​​frame 52. The snap-fit ​​frame 52 is snapped into the annular groove 54 outside the fixing rod 51 through the slot 55. That is, the inner width of the slot 55 is smaller than the diameter of the fixing rod 51, so the snap-fit ​​frame 52 is snapped onto the outside of the fixing rod 51, which can snap and lock the second flange plate 4.

[0040] Example 2

[0041] Based on Embodiment 1, the limiting component 53 includes a limiting block 531 and a positioning rod 532. The limiting block 531 is symmetrically sleeved in the annular groove 54. One side of the snap-fit ​​frame 52 is provided with an installation groove corresponding to the limiting block 531. One end of the positioning rod 532 is fixedly connected to one of the limiting blocks 531. One side of the other limiting block 531 is provided with a positioning groove corresponding to the positioning rod 532. Thus, under the action of the two limiting blocks 531 and without external force, the snap-fit ​​frame 52 can be stably snapped onto the outside of the fixing rod 51.

[0042] Furthermore, the limiting assembly 53 also includes a limiting plate 533, a limiting spring 534, a connecting rod 535, and a handle plate 536. The limiting plate 533 is fixedly connected to the end of the inner cavity of the mounting groove. The limiting spring 534 is disposed between the limiting plate 533 and the limiting block 531. The limiting spring 534 can provide an elastic compressive force to the limiting block 531, thereby ensuring the stability of the two limiting blocks 531 being snapped onto the outside of the fixed rod 51. One end of the connecting rod 535 is fixedly connected to the limiting block 531. The outer wall of the connecting rod 535 is slidably sleeved with the limiting spring 534. The outer wall of the connecting rod 535 is slidably inserted into the limiting plate 533. The handle plate 536 is fixedly connected to one end of the connecting rod 535. By pulling the two handle plates 536 in opposite directions, the limiting block 531 can be separated from the fixed rod 51, and the snap-fit ​​frame 52 can be directly pulled out. Then, the first flange plate 3 and the second flange plate 4 can be disassembled, thereby improving the convenience of installing or disassembling the discharge head 2.

[0043] 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.
