[0027] Please see Figure 1-2 This utility model provides a technical solution:

[0028] A granulation device for preparing submerged arc welding flux includes a base 1, a granulation device 3, and a stirring drum 8. Support legs 3 are provided at both ends of the bottom of the granulation device 3, and the bottom of the support legs 3 is fixedly connected to the top of the base 1. A feed pipe 22 is provided on one side of the top of the granulation device 3, and a solenoid valve 23 is provided on the surface of the feed pipe 22. The stirring drum 8 is provided on the top of the feed pipe 22, and a feed inlet 9 is provided on one side of the top of the stirring drum 8. A second drive motor 10 is provided at the center of the top of the stirring drum 8. The bottom output end of the second drive motor 10 is connected to the top of the stirring shaft 20. The stirring shaft 20 is located inside the stirring drum 8, and a plurality of stirring blades 21 are provided on the surface of the stirring shaft 20.

[0029] One end of the granulation equipment 2 has an inner cavity, and the other end of the outer surface of the granulation equipment 2 is provided with a third drive motor 16. The output end of the third drive motor 16 is connected to one end of the spiral shaft 17. The spiral shaft 17 is located inside the granulation equipment 2, and the surface of the spiral shaft 17 is provided with spiral blades 18.

[0030] The opening of the granulation equipment 2 is connected to a hot cutting die head 11 in a snap-fit ​​manner. A rotating shaft 14 is set at the center of the front side of the hot cutting die head 11. A first drive motor 4 is fixedly connected to the front end of the base 1 located on the side of the hot cutting die head 11. A rotating shaft 5 is set at the output end of the first drive motor 4.

During operation, the scraper can scrape off the raw material remaining on the inner wall of the granulation equipment to prevent waste.

[0031] Specifically, in use, the raw material is first poured into the feed inlet 9, then the second drive motor 10 is started. The rotation of the second drive motor 10 will cause the stirring shaft 20 to rotate, which in turn will cause the stirring blades 21 to rotate, thereby stirring the raw material and breaking up any lumps for easier processing. After stirring for a certain period of time, the second drive motor 10 is turned off, and the solenoid valve 23 is opened, allowing the raw material to enter the granulation equipment 2 to granulate it into submerged arc welding flux. Then, the third drive motor 16 and the first drive motor 4 are turned on. After rotation, the spiral shaft 17 will rotate, and the rotation of the spiral shaft 17 will cause the spiral blade 18 to rotate, thereby conveying the raw material to the hot cutting die head 11. At the same time, a cutting device is provided at the hot cutting die head 11 to cut the submerged arc welding flux. Specifically, the rotation of the first drive motor 4 will cause the rotating shaft 5 to rotate, the rotation of the rotating shaft 5 will cause the pulley 6 to rotate, the rotation of the pulley 6 will cause another pulley 6 to rotate through the transmission belt 7, thereby causing the rotating shaft 14 to rotate, the rotation of the rotating shaft 14 will cause the rotating blade 15 to rotate, and thus cut the submerged arc welding flux at the hot cutting die head 11.

[0032] It should be noted that the granulation equipment 2 in this utility model is also equipped with a heating mechanism. The heating mechanism in the heated granulation equipment 2 is a mature existing technology, and its specific internal structure and working principle will not be described in detail here.

[0033] Please see Figure 3-6 The outer surface of the opening of the granulation equipment 2 is provided with a second fixing plate 13, and the outer surface of the second fixing plate 13 is provided with a plurality of first fixing blocks 24. One end of the first fixing block 24 is provided with a through groove 25, and the bottom center of the through groove 25 is provided with a circular slot 26.

[0034] A first fixing plate 12 is provided on the outer surface of the hot cutting die head 11. The back of the first fixing plate 12 is in contact with the front of the second fixing plate 13. A plurality of second fixing blocks 27 are provided on the outer surface of the second fixing plate 13. The second fixing plate 27 includes a fixing block body 2701, a connecting rod 2702, a circular locking block 2703, and a push-pull plate 2704. One side of the fixing block body 2701 is in contact with the opening surface of the first fixing block 24. The connecting rod 2702 passes through the center of both ends of the fixing block body 2701. One end of the connecting rod 2702 is provided with a circular locking block 2704. 703, the circular locking block 2703 is snapped into the circular locking slot 26, the other end of the connecting rod 2702 is connected to the center of the back of the push-pull plate 2704, the top and bottom of the back of the push-pull plate 2704 are connected to the telescopic end of the telescopic rod 2705, the fixed end of the telescopic rod 2705 is fixed to the fixed block body 2701, and a buffer spring 2706 is sleeved on the surface of the telescopic rod 2705. One end of the buffer spring 2706 is connected to the fixed block body 2701, and the other end of the buffer spring 2706 is connected to the push-pull plate 2704.

[0035] Specifically, during use, a hot-cutting die 11 is snap-fitted to the opening of the granulation equipment 2. This is a mature existing technology, and its internal structure and working principle will not be described in detail here. However, during the granulation process, the hot-cutting die 11 will be subjected to a certain degree of force, which may cause it to fall off and affect granulation. In order to better fix the hot-cutting die 11 to the granulation equipment 2, after the hot-cutting die 11 is snap-fitted to the granulation equipment 2, the first fixing plate 12 will be connected to the second fixing plate 13. When the first fixing block 24 and the second fixing block 27 at the same position come into contact, the operator manually pushes the push-pull plate 2704, which will cause the telescopic rod 2705 to retract and compress the buffer spring 2706. During the movement of the push-pull plate 2704, the connecting rod 2702 will move forward. During the movement, when the circular locking block 2703 at the front end of the connecting rod 2702 engages with the circular locking groove 26, the hot cutting die head 11 and the granulation equipment 2 will be engaged again.

[0036] When the hot cutting die head 11 needs to be removed, the worker pulls the push-pull plate 2704 backward. At this time, the buffer spring 2706 will rebound, which will cause the telescopic rod 2705 to rebound to the initial position, and further cause the push-pull plate 2704 to return to the initial position.

[0037] Meanwhile, after the circular locking block 2703 at the front end of the connecting rod 2702 is engaged with the circular locking groove 26, the buffer spring 2706 will play a buffering role.

[0038] Working principle: The granulation equipment for preparing submerged arc welding flux of this utility model is not an integral connection between the hot cutting die 11 and the granulation equipment 2, but a snap-fit ​​connection. It can be easily separated from the granulation equipment 2, so that the hot cutting die 11 can be easily cleaned. It has certain practicality.

[0039] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
