Description

Technical Field

[0001] This utility model relates to the technical field of chemical machinery, and in particular to a crosslinking accelerator powder granulation device. Background Technology

[0002] Crosslinking accelerators are additives that assist crosslinking agents in the function of crosslinking systems. They are commonly used in rubber vulcanization, thermosetting resin curing, and medical aesthetic gel molding. During production, crosslinking accelerator powder needs to be granulated using a granulation device. In the prior art, utility model patent application number 202222319626.1 discloses a silane crosslinking material granulation device, which mainly consists of an extruder and an extrusion die. In use, the extrusion die is mounted on the extruder. The material is extruded through the extruder and enters the forming channel of the extrusion die, where it is formed into a columnar shape. The columnar material is then discharged from the forming channel and cut into granules by a slitting mechanism. However, this device has the following problem: after granulation, some material remains inside the forming channel of the extrusion die. Because the die and extruder are usually fixedly installed in existing devices, it is not easy to disassemble the die from the extruder and transfer it to a dedicated cleaning mechanism for cleaning, making the cleaning of the forming channel difficult and inconvenient to use. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a crosslinking accelerator powder granulation device that allows the molding channel used for molding raw materials to be disassembled from the extrusion die, facilitating the cleaning and replacement of the molding channel in the extrusion die, and is convenient to use, practical and reliable.

[0004] This utility model discloses a crosslinking accelerator powder granulation device, comprising a base plate, an extruder, and an extrusion die. The extruder is mounted on the upper part of the base plate and has a feed pipe. The extrusion die is mounted on the right side of the extruder. It also includes a cutting mechanism, a conveying mechanism, and a cooling mechanism. The extrusion die has multiple detachable mechanisms, each with a left-right communicating forming channel connected to the extruder. The cutting mechanism is located on the right side of the extrusion die and performs a cutting function. The conveying mechanism is located below the extrusion die and performs a conveying function. The cooling mechanism is mounted on the base plate and the extrusion die and performs a cooling function. The extruder is equipped with a heating device and a thermometer. During the granulation of the crosslinking accelerator powder, a certain amount of accelerator powder and liquid binder are added to the extruder. The extruder is then opened, and the accelerator powder and various raw materials are mixed. The raw material is heated, causing the accelerator powder in the extruder to become a viscous paste. Simultaneously, the extruder extrudes the paste into multiple detachable mechanisms on the extrusion die. The paste is then shaped into a columnar form within the forming channels of these detachable mechanisms. The columnar material is then discharged from the right end of the extrusion die, where a cutting mechanism cuts it into multiple segments, granulating it and sending it to a conveying mechanism. The conveying mechanism then transports the granulated accelerator powder to the next processing step. When the accelerator powder granulation is complete and the forming channels need cleaning, the detachable mechanisms are removed from the extrusion die and transferred to a dedicated external cleaning system. This design allows for the removal of the forming channels from the extrusion die, facilitating cleaning and replacement of the forming channels. It is convenient, practical, and highly reliable.

[0005] Preferably, the detachable mechanism includes a forming tube and a mounting base. The extrusion die has multiple horizontally connected slides around its circumference. The forming tube is slidably installed in one of these slides. The mounting base is located at the right end of the forming tube and is bolted to the right end of the extrusion die. The forming tube has a horizontally connected forming channel. When forming raw materials, the raw materials enter the extrusion die in the extruder, then enter the forming channel of the forming tube and are formed into a columnar shape. The columnar raw materials are then cut into granules when discharged from the right end of the forming tube. When cleaning the forming channel inside the forming tube is required, the mounting base is removed from the extrusion die, the forming tube is removed from the slide groove of the extrusion die, and then the forming tube is transferred to a dedicated cleaning device to clean the forming channel. This facilitates the cleaning of the forming channel on the forming tube.

[0006] Preferably, the cutting mechanism includes a moving mechanism, a support plate, a drive motor, a rotating shaft, and multiple cutting blades. The support plate is mounted on the moving mechanism, which is used to move the support plate left and right. The drive motor is fixedly mounted on the support plate, and the rotating shaft is rotatably mounted on the support plate. The power output end of the drive motor is connected to the rotating shaft. The multiple cutting blades are all fixedly mounted on the rotating shaft and are located on the right side of the extrusion die. When the raw material is discharged from the right end of the extrusion die, the drive motor is turned on, and the drive motor drives the rotating shaft to rotate. The rotating shaft drives the multiple cutting blades to rotate, so that the raw material extruded from the extrusion die is cut into granules by the multiple cutting blades. The granulated raw material falls onto the conveying mechanism for transport, which facilitates the granulation of the raw material.

[0007] Preferably, the moving mechanism includes a linear module and a sliding plate. The linear module is fixedly mounted on the base plate, and the sliding plate is provided on the linear module. The linear module is used to move the sliding plate left and right. The support plate is fixedly mounted on the upper end of the sliding plate. When it is necessary to disassemble the forming tube and the mounting base at the right end of the extrusion mold, the linear module is opened, causing the sliding plate to move the support plate to the right, which in turn causes the rotating shaft to move the cutting blade to the right, moving the cutting blade away from the right side of the extrusion mold. This results in a larger space on the right side of the extrusion mold, avoiding interference with the cutting blade when disassembling the forming tube and improving safety.

[0008] Preferably, the conveying mechanism includes a belt conveyor with a conveyor belt, the front of which is located below the extrusion die. After the cutting blade cuts the columnar raw material, the cut granular raw material falls onto the conveyor belt. Then, the belt conveyor is turned on to transport the raw material to the next processing step for further processing.

[0009] Preferably, the cooling mechanism includes an inlet pipe, a drain pipe, a water tank, a delivery pump, a heat exchange pipe, a delivery pipe, and a return pipe. The heat exchange pipe is spiral-shaped and embedded in the inner wall of the extrusion die. The inlet end of the heat exchange pipe is connected to the inlet pipe, and the outlet end is connected to the drain pipe. The water tank is mounted on the base plate. The inlet end of the delivery pump is connected to the water tank, and the outlet end of the delivery pump is connected to the inlet pipe via the delivery pipe. The outlet end of the drain pipe is connected to the return pipe, and the outlet end of the return pipe is connected to the water tank. The return pipe is a shell-and-tube heat exchanger. When the raw material is in... During extrusion in the extrusion die, the delivery pump is turned on, allowing the coolant in the water tank to sequentially enter the heat exchange tube through the delivery pump, delivery pipe, and inlet pipe. The coolant cools the extrusion die through the heat exchange tube, thereby cooling the forming tube and the raw material in the extrusion die, promoting the forming of the raw material. Afterward, the coolant enters the tube side of the return tube through the drain pipe. In the return tube, the coolant exchanges heat with the cooling water in the shell side, causing the coolant to cool down and then flow back to the water tank. The cooling water in the shell side of the return tube is connected to an external cooling tower, which cools the water in the shell side.

[0010] Preferably, a temperature gauge is installed on the extrusion die; this facilitates the monitoring of the temperature of the extrusion die.

[0011] Preferably, rubber baffles are provided at both ends of the conveyor belt; this arrangement prevents raw materials from falling off at both ends of the conveyor belt during transport, thus improving reliability.

[0012] Compared with the prior art, the advantages of this utility model are: the forming channel used for forming raw materials can be disassembled from the extrusion die, which facilitates the cleaning and replacement of the forming channel in the extrusion die, making it convenient to use, practical and reliable.

[0015] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example

[0016] like Figures 1 to 5The crosslinking accelerator powder granulation device of this utility model includes a base plate 1, an extruder 2, an extrusion die 4, a cutting mechanism, a conveying mechanism, and a cooling mechanism. The extruder 2 is installed on the upper end of the base plate 1 and is equipped with a feed pipe 3. The extrusion die 4 is installed on the right side of the extruder 2 and is equipped with multiple detachable mechanisms. Each detachable mechanism has a left-right communicating forming channel that communicates with the extruder 2. The cutting mechanism is located on the right side of the extrusion die 4 and has a cutting function. The conveying mechanism is located below the extrusion die 4 and has a conveying function. The cooling mechanism is installed on the base plate 1 and the extrusion die 4 and has a cooling function. A heating device and a thermometer are installed inside the extruder 2. When granulating the crosslinking accelerator powder, a certain amount of accelerator powder and liquid binder are added to the extruder 2. Then, the extruder 2 is opened to mix the accelerator powder and various raw materials in the extruder 2. The raw material in extruder 2 is heated, causing the accelerator powder in extruder 2 to become a viscous paste. Simultaneously, extruder 2 extrudes the paste into multiple detachable mechanisms on extrusion die 4. The paste is then shaped into a columnar form within the forming channels of these detachable mechanisms. The columnar material is then discharged from the right end of extrusion die 4. A cutting mechanism cuts the columnar material into multiple segments, granulating it, which then falls onto a conveying mechanism. The conveying mechanism then transports the granulated accelerator powder to the next processing step for further processing. When the accelerator powder granulation is complete and the forming channels need cleaning, the detachable mechanisms are removed from extrusion die 4 and transferred to a dedicated external cleaning mechanism. This design allows for the removal of the forming channels used for raw material shaping from extrusion die 4, facilitating cleaning and replacement of the forming channels. It is convenient to use and offers high practicality and reliability.

[0017] like Figure 1 and Figure 5 The detachable mechanism includes a forming tube 5 and a mounting base 6. Multiple left-right interconnected slides are arranged around the circumference of the extrusion die 4. The forming tube 5 is slidably installed in one of these slides. The mounting base 6 is located at the right end of the forming tube 5 and is bolted to the right end of the extrusion die 4. The forming tube 5 has left-right interconnected forming channels. When forming raw materials, the raw materials enter the extrusion die 4 in the extruder 2, and then enter the forming channels of the forming tube 5 to be formed into a columnar shape. The columnar raw materials are then cut into granules when discharged from the right end of the forming tube 5. When cleaning the forming channels inside the forming tube 5 is required, the mounting base 6 is removed from the extrusion die 4, the forming tube 5 is removed from the slide groove of the extrusion die 4, and then the forming tube 5 is transferred to a dedicated cleaning device to clean the forming channels. This facilitates the cleaning of the forming channels on the forming tube 5.

[0018] like Figure 4The cutting mechanism includes a moving mechanism, a support plate 7, a drive motor 8, a rotating shaft 9, and multiple cutting blades 10. The support plate 7 is mounted on the moving mechanism, which is used to move the support plate 7 left and right. The drive motor 8 is fixedly mounted on the support plate 7, and the rotating shaft 9 is rotatably mounted on the support plate 7. The power output end of the drive motor 8 is connected to the rotating shaft 9. The multiple cutting blades 10 are all fixedly mounted on the rotating shaft 9 and are located on the right side of the extrusion die 4. When the raw material is discharged from the right end of the extrusion die 4, the drive motor 8 is turned on, and the drive motor 8 drives the rotating shaft 9 to rotate. The rotating shaft 9 drives the multiple cutting blades 10 to rotate, so that the raw material extruded from the extrusion die 4 is cut into granules by the multiple cutting blades 10. The granulated raw material falls onto the conveying mechanism for conveying, which facilitates the granulation of the raw material.

[0019] like Figure 1 and Figure 4 The moving mechanism includes a linear module 11 and a sliding plate 12. The linear module 11 is fixedly installed on the base plate 1, and the sliding plate 12 is provided on the linear module 11. The linear module 11 is used to move the sliding plate 12 left and right. The support plate 7 is fixedly installed on the upper end of the sliding plate 12. When it is necessary to disassemble the forming tube 5 and the mounting base 6 at the right end of the extrusion mold 4, the linear module 11 is opened, so that the sliding plate 12 drives the support plate 7 to move to the right, which in turn drives the rotating shaft 9 to move the cutting blade 10 to the right, so that the cutting blade 10 is away from the right side of the extrusion mold 4, so that the space on the right side of the extrusion mold 4 is larger, avoiding interference with the cutting blade 10 when disassembling the forming tube 5, and improving safety.

[0020] like Figure 1 The conveying mechanism includes a belt conveyor 13, on which a conveyor belt 14 is provided. The front part of the conveyor belt 14 is located below the extrusion die 4. After the cutting blade 10 cuts the columnar raw material, the cut granular raw material falls onto the conveyor belt 14. Then, the belt conveyor 13 is turned on so that the conveyor belt 14 conveys the raw material and transports the granular raw material to the next processing step for further processing.

[0021] like Figure 1 and Figure 2The cooling mechanism includes an inlet pipe 15, a drain pipe 16, a water tank 17, a delivery pump 18, a heat exchange pipe, a delivery pipe 19, and a return pipe 20. The heat exchange pipe is spiral-shaped and embedded in the inner wall of the extrusion die 4. The inlet end of the heat exchange pipe is connected to the inlet pipe 15, and the outlet end is connected to the drain pipe 16. The water tank 17 is mounted on the base plate 1. The inlet end of the delivery pump 18 is connected to the water tank 17, and the outlet end of the delivery pump 18 is connected to the inlet pipe 15 through the delivery pipe 19. The outlet end of the drain pipe 16 is connected to the return pipe 20, and the outlet end of the return pipe 20 is connected to the water tank 17. The return pipe 20 is a shell-and-tube heat exchanger. When the raw material is extruded in the extrusion die 4, the delivery pump 18 is turned on, so that the coolant in the water tank 17 enters the heat exchange tube in sequence through the delivery pump 18, delivery pipe 19 and water inlet pipe 15. The coolant cools the extrusion die 4 through the heat exchange tube, thereby cooling the forming tube 5 and the raw material in the extrusion die 4, promoting the forming of the raw material. Afterwards, the coolant enters the tube side of the return pipe 20 through the drain pipe 16. The coolant exchanges heat with the cooling water in the shell side in the return pipe 20, so that the coolant is cooled down and flows back to the water tank 17. The cooling water in the shell side of the return pipe 20 is connected to the external heat dissipation tower, and the water in the shell side is cooled by the heat dissipation tower.

[0022] A temperature gauge is installed on the extrusion die 4; this feature facilitates the monitoring of the temperature of the extrusion die 4. Example

[0023] Based on Example 1, rubber baffles are provided at both ends of the conveyor belt 14; through the above-mentioned arrangement, the raw materials are prevented from falling off at both ends of the conveyor belt 14 when being conveyed on the conveyor belt 14, thereby improving reliability.

[0024] It should be added that: all electrical equipment in this case is connected to an external controller, which coordinates and controls the operation of each piece of electrical equipment.

[0025] The extruder 2, extrusion die 4, linear module 11, cutting blade 10, belt conveyor 13, water tank 17, conveying pump 18, and conveying pipe 19 of the crosslinking accelerator powder granulation device of this utility model are all purchased from the market.
