DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 - 6 The utility model provides a technical solution: a tunnel furnace heating device, including a fixed frame 1, the upper end of the fixed frame 1 is driven and provided with a conveyor belt 2, one end of the fixed frame 1 is rotatably connected to the inner side of a fixed support 3, the inner side of the fixed support 3 is driven and connected to a feeding belt 4, the outer end of the fixed frame 1 is fixedly connected to a driving motor 5, the output end of the driving motor 5 is fixedly connected to an active roller 20, the other end of the active roller 20 is rotatably connected to the fixed support 3, the lower end of the fixed support 3 is rotatably connected to a driven roller 21, the active roller 20 and the driven roller 21 are located at the inner ends of the feeding belt 4 and are arranged against each other, the upper end of the fixed support 3 is fixedly connected to a separation mechanism, the lower end of the fixed support 3 is fixedly connected to a hopper 6, and the lower end of the fixed support 3 is provided with a supporting mechanism; the material is placed in the hopper 6, and the active roller 20 is driven to rotate by the driving motor 5, and the fixed support A fixing pin for supporting the driven roller 21 is fixed on the inner side away from one end of the active roller 20. The feeding belt 4 sleeved on the active roller 20 rotates. The feeding belt 4 is a rubber belt. The friction of the belt drives the driven roller 21 to rotate on the fixing pin, so that the driving motor 5 drives the feeding belt 4 to transmit. When the feeding belt 4 rotates, the material in the hopper 6 is transported upward. The material is evenly separated when passing through the separation mechanism, so that the material can be transported separately at intervals. The fixed support 3 adjusts the upper and lower angles according to the size and weight of the material. The heavier workpiece adjusts the angle more slowly. After the angle is adjusted, the fixed support 3 supports the fixed support 3 through the support mechanism. This design can facilitate the placement and loading of the workpiece material after the first baking process, and improve the efficiency of loading and baking the workpiece.

[0023] like Figure 4As shown in the figure, the separating mechanism includes: a fixed rod 7, which is fixed at the middle edge position of the fixed support 3. An adjusting rod 8 is slidably arranged on the two fixed rods 7. A fixing knob 9 is threadedly connected to the outer end of the adjusting rod 8. The outer end of the adjusting rod 8 is fixedly connected to a separating plate 11. The number of separating plates 11 is multiple and they are arranged at equal intervals. The fixed rod 7 is fixed at the edge position of the fixed support 3. The adjusting rod 8 sleeved and slid on the fixed rod 7 can drive the separating plate 11 to move up and down, and the separating plate 11 is adjusted according to the size of the material. And the adjusting rod 8 is fixed and limited by the rotation of the fixing knobs 9 on both sides. Through the separating plate 11, the material can be separated and distributed at the position of the feeding belt 4.

[0024] As Figure 5 shown in the figure, the supporting mechanism includes: a connecting rod 13, which is fixed at the lower end of the hopper 6. A connecting plate 12 is fixedly connected to the lower end of the hopper 6. The connecting rod 13 is fixedly arranged between the connecting plates 12. A limiting ring 14 is fixedly connected to the connecting rod 13. A connecting head 15 is rotatably connected between the two limiting rings 14. A screw rod is threadedly connected to the outer end of the connecting head 15. A threaded rod 16 is fixedly connected to the lower end of the connecting head 15. A supporting sleeve 17 is threadedly connected to the lower end of the threaded rod 16. The lower end of the supporting sleeve 17 abuts against the ground. The connecting plate 12 is fixedly connected to the fixed support 3. The connecting rod 13 is fixed between the connecting plates 12. The connecting rod 13 is circular. Symmetrical limiting rings 14 are fixed on the connecting rod 13. A connecting head 15 is rotatably connected between the limiting rings 14. The connecting head 15 is fixed by being abutted against the connecting rod 13 through threaded connection with the screw rod. A threaded rod 16 is fixedly connected to the lower end of the connecting head 15. A supporting sleeve 17 is threadedly connected to the lower end of the threaded rod 16. The rotation of the supporting sleeve 17 can move up and down to abut against the ground to form a support.

[0025] As Figure 3 shown in the figure, a receiving hopper 18 is fixedly connected to the inside of the fixed frame 1 at the discharging end of the conveyor belt 2. An arc-shaped plate 19 is fixed inside the receiving hopper 18. The inner end of the receiving hopper 18 is arranged at the lower end of the conveyor belt 2. The receiving hopper 18 is convenient for the discharging and sorting of materials. The arc-shaped plate 19 at the inner end of the receiving hopper 18 is matched with the conveyor belt 2. In this way, when the material is discharged, it can directly fall into the receiving hopper 18, thus avoiding the falling of the material.

[0026] As Figure 4 and Figure 6 shown in the figure, a plurality of retaining pieces 10 are fixedly connected to the lower end of the adjusting rod 8 and they are arranged at equal intervals. The retaining pieces 10 are elastically arranged. The position of the retaining pieces 10 moves with the up and down movement of the adjusting rod 8. According to the height of the material, the distance between the lower end of the retaining piece 10 and the feeding belt 4 is controlled by the adjusting rod 8. In this way, the height of the material is limited by the retaining piece 10 to avoid the accumulation of materials during feeding.

[0027] As Figure 4 shown, the partition plate 11 and the adjusting rod 8 are fixedly connected by magnetic attraction; the partition plate 11 and the adjusting rod 8 are fixed by magnetic attraction, so that the position of the partition plate 11 can be adjusted, and the number of partition plates 11 can be adjusted, and the partition plate 11 is adjusted according to the size and amount of the material.

[0028] It should be noted that; multi-stage heating devices or multi-stage UV lamps can be designed inside the tunnel furnace, because according to different inks sprayed, the curing heating methods are completely different. If it is ordinary ink, then the heating curing method is used. If it is UV ink, UV lamps are used for light curing. These are all prior arts, so there are no illustrations.

[0029] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention.
