Currently, traditional thermosetting oven heating devices have several drawbacks: First, heating components are mostly fixed, making disassembly and replacement cumbersome and affecting continuous operation when heating elements are damaged; second, the workpiece support structure is fixed in position, making it impossible to adjust the support position and height according to the size and shape of the workpiece, resulting in uneven heating of some workpieces and affecting the curing effect; third, the stability of the support structure after adjustment is insufficient, making it prone to displacement during heating, posing a safety hazard; and fourth, the oven door design is unreasonable, making opening and closing inconvenient and affecting the efficiency of workpiece loading and unloading. Summary of the Invention

[0003] In view of the above situation and to overcome the defects of the prior art, the present invention provides a heating device for a thermosetting oven, which effectively solves the problems currently on the market.

[0004] The technical solution adopted by this invention is as follows: This invention proposes a heating device for a thermosetting oven, including a heating chamber, a flip-up door panel on the heating chamber, a hinge connecting the flip-up door panel to the heating chamber, fixing blocks on both sides of the heating chamber, a heater housing mounted on the fixing blocks, an extrusion plate on the heater housing, a fastening bolt connecting the extrusion plate to the fixing blocks, a heating tube installed inside the heater housing, a fixed base inside the heating chamber, a rotating shaft mounted on the fixed base, a torsion spring connecting the rotating shaft to the fixed base, a sliding plate on the fixed base, and fixing teeth at the bottom of the sliding plate.

[0005] Furthermore, a fixed sleeve is provided on the upper surface of the sliding plate, a rotating ring is provided at the top end of the fixed sleeve, a threaded rod is provided inside the fixed sleeve, a bearing plate is installed at the top end of the threaded rod, and a guide rod is provided on the bottom surface of the bearing plate.

[0006] Furthermore, the flip-up door panels are symmetrically arranged on the heating chamber, and the flip-up door panels form a flip structure with the heating chamber through hinges. The fixing blocks are symmetrically arranged on the heating chamber and are fixedly connected to the heating chamber.

[0007] Furthermore, the heater housing is detachably connected to the heating box, the extrusion plate abuts against the outer surface of the heater housing, and the fastening bolts penetrate and connect to the heater housing.

[0008] Furthermore, the fastening bolt penetrates the extrusion plate, the fastening bolt is threadedly connected to the fixing block, and the heating tube is detachably connected to the heater housing.

[0009] Furthermore, the fixed base is fixedly connected to the heating box, the rotating shaft is rotatably connected to the fixed base, one end of the torsion spring is fixedly connected to the fixed base, and the other end of the torsion spring is fixedly connected to the rotating shaft.

[0010] Furthermore, the drive gear is fixedly connected to the top end of the rotating shaft, the sliding plate is slidably connected to the fixed base, the fixed teeth are fixedly connected to the sliding plate, and the fixed teeth are meshed with the drive gear.

Therefore, they should not be construed as limitations on this invention.

[0026] like Figures 1-5As shown, the present invention proposes a heating device for a thermosetting oven, including a heating chamber 1, a flip-up door panel 2 on the heating chamber 1, a hinge 3 connecting the flip-up door panel 2 and the heating chamber 1, fixing blocks 4 on both sides of the heating chamber 1, a heater housing 5 mounted on the fixing blocks 4, an extrusion plate 6 on the heater housing 5, a fastening bolt 7 connecting the extrusion plate 6 and the fixing blocks 4, a heating tube 8 installed inside the heater housing 5, a fixed base 9 inside the heating chamber 1, a rotating shaft 10 mounted on the fixed base 9, a torsion spring 11 connecting the rotating shaft 10 and the fixed base 9, a sliding plate 13 on the fixed base 9, and fixing teeth 14 at the bottom of the sliding plate 13.

[0027] A fixed sleeve 15 is provided on the upper surface of the sliding plate 13. A rotating ring 16 is provided at the top of the fixed sleeve 15. A threaded rod 17 is provided inside the fixed sleeve 15. A bearing plate 18 is installed at the top of the threaded rod 17. A guide rod 19 is provided on the bottom surface of the bearing plate 18.

[0028] The flip-up door panel 2 is symmetrically arranged at the front opening of the heating chamber 1; the flip-up door panel 2 forms a 0-180 degree flip-up structure with the heating chamber 1 through the hinge 3; the fixing block 4 is symmetrically arranged on the left and right outer walls of the heating chamber 1, and the fixing block 4 is vertically welded to the side wall of the heating chamber 1.

[0029] The flip door panel 2 rotates around the hinge 3 to open and close the heating box 1. The fixing block 4 provides an installation base for the heater shell 5, making it easy to pick up and put down the workpiece. The fixing block 4 ensures that the heater shell 5 is installed stably.

[0030] The heater housing 5 is detachably connected to the side wall of the heating chamber 1 via the extrusion plate 6 and the fastening bolt 7; the extrusion plate 6 is tightly pressed against the outer surface of the heater housing 5; the fastening bolt 7 passes horizontally through the heater housing 5.

[0031] The fastening bolts 7 fix the extrusion plate 6 and the heater housing 5 to the fixing block 4. The heater housing 5 can be removed by removing the bolts, which facilitates the inspection and replacement of the heater housing 5 and the internal heating tube 8. The connection is firm and prevents loosening.

[0032] Fastening bolt 7 horizontally penetrates both ends of extrusion plate 6; fastening bolt 7 is threaded to the internal screw hole of fixing block 4; heating tube 8 is detachably connected to the inner wall of heater housing 5 via buckle.

[0033] In this embodiment, tightening the fastening bolts 7 causes the extrusion plate 6 to press against the heater housing 5, and the heating tube 8 is connected to the power supply to generate heat, ensuring that the heater housing 5 is installed stably. The heating tube 8 is detachable for easy replacement and maintenance.

[0034] The fixed base 9 is horizontally welded to the center of the bottom surface inside the heating box 1; the rotating shaft 10 is rotatably connected to the center of the fixed base 9 through a bearing; one end of the torsion spring 11 is welded to the upper surface of the fixed base 9, and the other end is welded to the lower part of the rotating shaft 10.

[0035] In this embodiment, when the rotating shaft 10 rotates, the torsion spring 11 stores force. After the rotating shaft 10 is released, the torsion spring 11 drives it to reset, realizing the automatic reset of the rotating shaft 10, which facilitates the rapid adjustment and reset of the position of the sliding plate 13.

[0036] The drive gear 12 is keyed to the top of the rotating shaft 10; the sliding plate 13 is slidably connected to the upper surface of the fixed base 9 along the length of the fixed base 9; the fixed tooth 14 meshes with the tooth of the drive gear 12.

[0037] In this embodiment, the rotating shaft 10 drives the drive gear 12 to rotate. The drive gear 12 drives the sliding plate 13 to slide along the fixed base 9 through meshing with the fixed gear 14, converting the rotational motion into linear motion, so as to realize the smooth movement of the sliding plate 13 and adjust the position of the workpiece in the heating box 1.

[0038] The fixing sleeves 15 are evenly distributed on the upper surface of the sliding plate 13 with the center of the sliding plate 13 as the symmetrical point; the fixing sleeves 15 are vertically welded to the upper surface of the sliding plate 13.

[0039] The fixed sleeve 15 provides installation and sliding space for the threaded rod 17 and the guide rod 19, supports the bearing plate 18, ensures the stable installation of the bearing plate 18, and provides basic support for the height adjustment structure.

[0040] The rotating ring 16 is rotatably connected to the top of the fixed sleeve 15 via a bearing; the threaded rod 17 is slidably connected to the inner wall of the fixed sleeve 15 in the vertical direction; and the threaded rod 17 passes through and is threadedly connected to the center of the rotating ring 16.

[0041] When the rotating ring 16 rotates, it drives the threaded rod 17 to slide up and down along the fixed sleeve 15 through the threaded transmission, thereby realizing the lifting and lowering adjustment of the threaded rod 17 and providing power for the height adjustment of the bearing plate 18.

[0042] The bearing plate 18 is rotatably connected to the top of the threaded rod 17 via a bearing; a cylindrical guide rod 19 is vertically installed at each of the four corners of the bottom surface of the bearing plate 18; the guide rod 19 is slidably connected to the fixed sleeve 15 in the vertical direction.

[0043] In this embodiment, the threaded rod 17 moves up and down, causing the bearing plate 18 to move synchronously. The guide rod 19 slides along the inner wall of the fixed sleeve 15 with the bearing plate 18, ensuring that the bearing plate 18 is horizontally stable during the lifting and lowering process, avoiding tilting, and ensuring that the workpiece is heated evenly.

[0044] In practical use, the fixing blocks 4 on both sides of the heating chamber 1 provide the mounting base for the heater shell 5. The heater shell 5 is fixed to the fixing blocks 4 by the extrusion plate 6 and the fastening bolts 7. The heating tube 8 inside the heater shell 5 generates heat after being connected to the power supply. The heat is transferred to the inside of the heating chamber 1 through the heater shell 5 to achieve the heating inside the chamber. When it is necessary to repair or replace the heating tube 8, the heater shell 5 can be removed by disassembling the fastening bolts 7. The operation is simple.

[0045] The fixed base 9 is installed on the bottom surface inside the heating box 1. The rotating shaft 10 is connected to the fixed base 9 through a bearing. The drive gear 12 at the top of the shaft meshes with the fixed gear 14 at the bottom of the sliding plate 13. When the rotating shaft 10 is rotated, the drive gear 12 drives the sliding plate 13 to slide along the length of the fixed base 9. After the rotating shaft 10 is released, the torsion spring 11 drives the rotating shaft 10 to reset, realizing the automatic reset of the sliding plate 13. When the 2 is opened, the sliding plate 13 can automatically slide out from the inside of the heating box 1 for easy material removal.

[0046] The fixed sleeve 15 on the sliding plate 13 provides installation space for the threaded rod 17 and the guide rod 19. By rotating the rotating ring 16 at the top of the fixed sleeve 15, the threaded rod 17 is driven to rise and fall within the fixed sleeve 15 through threaded transmission, thereby driving the bearing plate 18 to move up and down to adjust the bearing height. The guide rod 19 on the bottom surface of the bearing plate 18 slides along the inner wall of the fixed sleeve 15 to ensure the horizontal stability of the bearing plate 18 during the rising and falling process.

[0047] The flip-up door panel 2 is connected to the heating chamber 1 via a hinge 3, and can be flipped 0-180 degrees around the hinge 3, thereby opening and closing the heating chamber 1 to facilitate the loading and unloading of workpieces. The above is the overall workflow of the present invention. This step can be repeated next time it is used. The actual operation process is very simple and easy.
