Description

Technical Field

[0001] The utility model relates to the technical field of rotational molding heating furnaces, and particularly relates to a rotary rotational molding heating furnace. Background Art

[0002] The rotational molding process is widely used in industrial production. However, at present, most of the rotational molding processes use natural gas open-flame heating. This kind of rotational molding process has obvious disadvantages, such as low energy utilization rate. Due to open heating, most of the heat is dissipated, resulting in long heating time and high heating cost.

[0003] An electric heating rotational molding machine disclosed in Chinese Patent CN208826906U includes a furnace door. A furnace door pulley group is arranged at the front end of the furnace door. A rotating gear ring is arranged at the front end of the furnace door pulley group. A furnace door slideway is arranged inside the rotating gear ring. A driving gear ring follower is arranged at the lower part of one side of the rotating gear ring. A driving gear ring is arranged below the other side of the rotating gear ring. A heating furnace swing frame is arranged below the furnace door at the lower end of the driving gear ring. A pulley group is arranged at the lower end of the heating furnace swing frame. A connecting plate is arranged at one side of the furnace door at the upper end of the heating furnace swing frame. A swing rotating shaft penetrates through the outer surface of one side of the connecting plate. An air duct is arranged at the rear end of the furnace door slideway at the upper part inside the furnace door.

[0004] When the above-mentioned existing heating rotational molding machine is in use, the rotating gear ring on the driving gear ring follower is driven to rotate by the driving gear ring, so that the roller of the rotational molding machine can rotate. The mold inside the rotational molding machine can be heated more evenly through the swing of the swing rotating shaft. However, the swing amplitude of the swing rotating shaft is small, which cannot effectively improve the heating efficiency of the mold and results in low production efficiency.

[0023] Please refer to Figures 1-3 , the present invention provides a technical solution: a rotary rotational molding heating furnace, including a base 1, and L-shaped brackets 2 are fixedly installed on both sides of the base 1.

[0024] A heating furnace 3 is rotatably installed between the two L-shaped brackets 2.

[0025] Specifically, support rods 12 are fixedly installed at the top ends of the opposite surfaces of the two L-shaped brackets 2, and a rotating block 13 is rotatably installed at the opposite ends of the two support rods 12. A V-shaped plate 14 is rotatably installed at the bottom end of the rotating block 13, and the bottom end of the V-shaped plate 14 is fixedly connected to the top end of the heating furnace 3.

[0026] An arc-shaped chute 4 is opened on the upper end surface of the base 1, a slider 5 is slidably installed inside the arc-shaped chute 4, a first motor 6 is fixedly installed at the top end of the slider 5, and the output shaft of the first motor 6 is fixedly connected to the bottom end of the heating furnace 3. Driving components for driving the slider 5 to move are arranged on both sides of the base 1.

[0027] The driving components include a slideway 7, an electric push rod 8, a connecting rod 9, and a guiding frame 10. The slideway 7 and the electric push rod 8 are both fixedly installed on the side wall of the base 1. The connecting rod 9 is fixedly connected to the side wall of the slider 5; one end of the connecting rod 9 away from the slider 5 is slidably and limitably connected to the inside of the guiding frame 10. The bottom end of the guiding frame 10 is slidably installed inside the slideway 7. The telescopic end of the electric push rod 8 is fixedly connected to the guiding frame 10.

[0028] To ensure the stability of the connection between the connecting rod 9 and the guiding frame 10, limiting blocks 11 are fixedly installed on both sides of the connecting rod 9 corresponding to the guiding frame 10. The guiding frame 10 is slidably and limitably arranged between the two limiting blocks 11.

[0029] A feed inlet is opened on one side of the top end of the heating furnace 3, and an end cover 15 is rotatably installed inside the feed inlet.

[0030] A shaft rod 16 is rotatably installed at the inner top end of the heating furnace 3, a stirring rod 17 is fixedly installed at the bottom end of the shaft rod 16, and a second motor 18 is fixedly installed on the upper end surface of the heating furnace 3. The output shaft of the second motor 18 is fixedly connected to the shaft rod 16.

[0031] To heat the mold, a plurality of heating coils 19 are evenly and fixedly installed on the inner wall of the heating furnace 3.

[0032] Working principle:

[0033] During use, by opening the end cover 15, the mold material is placed inside the heating furnace 3, the heating coils 19 are powered on, and the first motor 6, the electric push rod 8, and the second motor 18 are started. The first motor 6 rotates to drive the heating furnace 3 to rotate, and the heating furnace 3 rotates around the axis of the rotating block 13 through the V-shaped plate 14.

[0034] Initially, the slider 5 is located at the lowest end of the arc-shaped chute 4. The electric push rod 8 is started to push the guide frame 10 to move leftward. The leftward movement of the guide frame 10 drives the connecting rod 9 to move. Since the slider 5 is limited and slidably installed inside the arc-shaped chute 4. The movement of the connecting rod 9 drives the slider 5 to slide leftward inside the arc-shaped chute 4, and causes the connecting rod 9 to slide upward inside the guide frame 10. When the slider 5 is pushed to the leftmost side of the arc-shaped chute 4, the telescopic end of the electric push rod 8 retracts, thereby driving the slider 5 to move rightward inside the arc-shaped chute 4, and causing the connecting rod 9 to slide downward inside the guide frame 10.

[0035] When the slider 5 is pulled to the rightmost side of the arc-shaped chute 4, the telescopic end of the electric push rod 8 extends, and again pushes the slider 5 to move leftward, thereby causing the slider 5 to move left and right reciprocally inside the arc-shaped chute 4. While the slider 5 moves, it drives the first motor 6 and the heating furnace 3 to move synchronously, causing the rotating block 13 to swing left and right between the two support rods 12. This causes the heating furnace 3 to swing left and right on the base 1 with a relatively large swing amplitude, making the heating of the mold inside the heating furnace 3 more uniform, thereby improving the production efficiency.

[0036] The second motor 18 is started to drive the shaft rod 16 to rotate, the shaft rod 16 rotates to drive the stirring rod 17 to rotate, and the stirring rod 17 rotates to mix and stir the mold material inside the heating furnace 3.

[0037] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the technical field, various changes can be made without departing from the purpose of the present invention.
