The motor 2 is installed on the inner wall of the rotomolding machine 1, and the output shaft of the motor 2 passes through the rotomolding machine 1 and is connected to the first rotating shaft 3. The first rotating shaft 3 The front end is connected with a rotating frame 4, which is used for rotational molding. The rotating frame 4 is in an inverted shape. The inner side of the rotating frame 4 is symmetrically connected with mounting rods 6. The two mounting rods 6 are connected to the first connecting plate 7 on the opposite sides. The first connecting plate 7 is symmetrically slidably connected with the first sliding rods 8. A first fixing plate 9 is connected between the inner ends of the two first sliding rods 8 to fix the model frame. A first spring 10 is connected between the first fixing plate 9 and the first connecting plate 7. A second rotating shaft 11 is rotatably connected in the rotating frame 4 for rotating the connecting frame 12. The front end of the second rotating shaft 11 is connected to the connecting frame 12 for rotating the connecting frame 12. In order to adjust the position of the second fixed plate 15, a bidirectional screw 13 is connected to the inside of the connecting frame 12 by a thread, a guide rod 14 is connected to the connecting frame 12, and the bidirectional screw 13 and the guide rod 14 are symmetrically slidably connected to the second fixed plate 15 for fixing the model frame, a cross plate 16 is connected to the second rotating shaft 11, and a plurality of fixing grooves 17 are evenly spaced on the cross plate 16, and a connecting frame 18 is symmetrically connected to the rear side of the rotating frame 4, and a second sliding rod 19 is slidably connected to the connecting frame 18, and a fixing block 20 is connected to the front end of the second sliding rod 19 to fix the cross plate 16 and fix it. The fixed block 20 passes through the rotating frame 4 and is snap-fitted with the fixed groove 17. A second spring 21 is connected between the fixed block 20 and the connecting frame 18. A connecting rod 22 is connected between the rear sides of the two second sliding rods 19 to facilitate pulling the second sliding rods 19. The two second fixed plates 15 are threadedly connected to the opposite sides with fixing screws 23. The fixing screws 23 are connected with a connecting block 24. The connecting block 24 is in contact with the second fixed plate 15. A rotating handle 25 is connected to the left side of the connecting frame 12 to facilitate rotating the bidirectional screw 13. The rotating handle 25 passes through the connecting frame 12 and is fixedly connected to the bidirectional screw 13.
[0023] When the device is needed, when a smaller model frame needs to be rotomolded, the user places the two model frames in the grooves on the first fixing plate 9 and the second fixing plate 15, and then rotates the rotating handle 25, the rotating handle 25 drives the bidirectional screw 13 to rotate, and the rotation of the bidirectional screw 13 drives the two second fixing plates 15 to move outward along the guide rod 14. When the two second fixing plates 15 move to a suitable position, the rotating handle 25 is stopped to facilitate fixing the smaller model frame, and then the motor 2 is turned on, the output shaft of the motor 2 drives the first rotating shaft 3 to rotate, and the first rotating shaft 3 drives the rotating frame 4 and all the components thereon. The motor 2 is turned on and the rotational molding is started. When the rotational molding is completed, the motor 2 is turned off and the rotating handle 25 is rotated. The rotating handle 25 drives the bidirectional screw 13 to rotate. The bidirectional screw 13 drives the two second fixing plates 15 to move inward along the guide rod 14. When the second fixing plates 15 move to a suitable position, the rotating handle 25 is released to make them disengage from the smaller model frame. The model frame can then be removed and demoulding and other processes can be performed. When the larger model frame needs to be rotationally molded, the user pulls the connecting rod 22 backward, and the connecting rod 22 drives the second sliding rod 19 to move backward. The second sliding rod 19 with The movable fixing block 20 moves backward, the fixing block 20 moves out of contact with the fixing groove 17, the second spring 21 is compressed, and then the second rotating shaft 11 is rotated to ninety degrees, and the second rotating shaft 11 drives all the components thereon to rotate. When the second rotating shaft 11 is rotated, the user can loosen the connecting rod 22, and the second spring 21 is reset, so that the second sliding rod 19 drives the fixing block 20 and the connecting rod 22 to move forward, and the fixing block 20 moves to contact with the fixing groove 17 and is stuck therein, completing the fixing of the cross plate 16 and the second rotating shaft 11, and then the connecting block 24 is placed on the inner wall of the second fixing plate 15, and then the fixing screws are tightened. 23 is placed on the connecting block 24. After the fixing screw 23 is placed, the fixing screw 23 is rotated to rotate along the connecting block 24. When the fixing screw 23 is rotated to a suitable position, the fixing screw 23 is no longer rotated, and the larger model frame is placed in the groove between the two first fixing plates 9. The rotating handle 25 is rotated again, so that the second fixing plate 15 drives the connecting block 24 to move inward. When the connecting block 24 moves to fit and fix the larger model frame, the rotating handle 25 is no longer rotated to complete the fixing of the larger model frame. Subsequently, the above operation is repeated to complete the rotational molding operation of the larger model frame.
