A heating chamber is provided inside the furnace body. A gas burner assembly is installed on the inner wall of the heating chamber. A heat transfer plate is installed on the inner wall of the heating chamber. A gas storage tank is installed on the top of the furnace body.

The heating furnace mainly solves the problem of the complex structure of the traditional heating furnace, but its heating furnace has no protection structure. When the temperature of the furnace body is relatively high, if the cover plate is opened, it is easy to cause scalding and there is a safety hazard. Summary of the Invention

A sensor is installed on the outer wall of the cover plate. A display screen is installed on the outer wall of the cover plate. A workpiece is installed on the inner bottom wall of the furnace body.

[0019] Preferably, the working steps of this heating furnace are as follows:

[0020] S1. The gas burner assembly emits flames, heating the heat transfer plate. The heat transfer plate then transfers heat to the heating block, creating a heat storage heating area. The gas tank stores inert gas. Before heating, an air pump ejects the inert gas from the gas outlet plate through an air pipe, replacing the oxygen-containing air with the inert gas. This structure separates the redox reaction at the flame from the heating area. Furthermore, the inert gas protects the workpiece from oxidation during heating, thereby improving the heating effect.

[0021] S2. During heating, its spring pops the heat insulation plate out of the groove, separating the heating area from the feeding area and the discharging area, so that the heat in the processing area can be quickly accumulated, reducing the heat dissipation. After heating is completed, its No. 1 motor rotates to drive the reel to rotate, and the rotation of the reel winds the pull rope, which pulls the connecting plate to move, and the movement of the connecting plate drives the heat insulation plate to move, so that the heat insulation plate can be retracted into the groove, thereby not affecting the movement of the workpiece. In addition, the heat insulation plate on the feeding side is equipped with a heat transfer plate, so that part of the heat in the heating area is transferred to the workpiece on the feeding side through the heat transfer plate, so that the workpiece can be preheated. When the preheated workpiece enters the processing area for heating again, its heating efficiency is improved, thereby reducing the high-power heating time in the processing area, thereby achieving energy saving;

[0022] S3. When the workpiece in the heating block is heated and the next workpiece needs to be heated, the No. 2 motor rotates to drive the gear to rotate, and the gear rotation drives the toothed plate to move, and the toothed plate moves to move the adjustment plate into the heating block. Then the No. 3 motor rotates to drive the screw to rotate, and the rotation of the screw drives the telescopic plate to move, so that the telescopic plate moves to one side of the workpiece, and then the adjustment plate moves to push the workpiece out of the processing area. Then, this structure is used to push the workpiece in the feeding area into the heating block. This structure allows the heating of the workpiece to be continuous, and there is no need to cyclically open the cover to add the workpiece, which also reduces heat loss.

[0023] S4. When the cover is closed, the fixed block is embedded in the card block, and the sensor detects the temperature of the feeding area of the furnace body in real time and displays it on the display screen. When the temperature rises, the No. 4 motor rotates to drive the threaded rod to rotate, and the rotation of the threaded rod drives the transmission plate to move, and the movement of the transmission plate drives the push plate to move, and the movement of the push plate drives the inclined block to move, and the movement of the inclined block drives the card block to move, and the card block moves and is inserted into the card slot, so that the cover is locked. This locking structure is controlled by the sensor. When the temperature is high, the cover is locked through this structure, thereby avoiding the cover being opened by mistake and causing burns, greatly improving safety.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The present invention is equipped with a heat transfer plate, a gas storage tank, and an air pump. The gas burner assembly emits flames, which heat the heat transfer plate. The heat transfer plate then transfers heat to the heating block, forming a heat storage heating area. The gas storage tank stores inert gas. Before heating, the air pump ejects the inert gas from the gas outlet plate through an air pipe, replacing the oxygen-containing air with the inert gas, filling the furnace body with the inert gas. This structure isolates the redox reaction at the flame from the heating area. Furthermore, the protection of the inert gas makes it less likely that the workpiece will undergo an oxidation reaction during heating, thereby improving the heating effect.

[0026] 2. The present invention is equipped with a reel, a pull rope and a heat insulation plate. During heating, its spring pops the heat insulation plate out of the groove, thereby isolating the heating area from the feeding area and the discharging area, so that the heat in the processing area can be quickly accumulated, reducing the heat dissipation. After heating is completed, its No. 1 motor rotates to drive the reel to rotate, and the rotation of the reel winds the pull rope, which pulls the connecting plate to move, and the movement of the connecting plate drives the heat insulation plate to move, so that the heat insulation plate can be retracted into the groove, thereby not affecting the movement of the workpiece. In addition, the heat insulation plate on the feeding side is equipped with a heat transfer plate, so that part of the heat in the heating area is transferred to the workpiece on the feeding side through the heat transfer plate, so that the workpiece can be preheated. When the preheated workpiece enters the processing area for heating again, its heating efficiency is improved, thereby reducing the high-power heating time in the processing area, thereby achieving energy saving.

[0027] 3. The present invention is equipped with an adjustment plate, a tooth plate and a screw. When the workpiece in the heating block is heated and the next workpiece needs to be heated, the No. 2 motor rotates to drive the gear to rotate, and the gear rotation drives the tooth plate to move. The tooth plate moves to move the adjustment plate into the heating block. Then the No. 3 motor rotates to drive the screw to rotate, and the rotation of the screw drives the telescopic plate to move, so that the telescopic plate moves to one side of the workpiece. Then the adjustment plate moves to push the workpiece out of the processing area. Then, using this structure, the workpiece in the feeding area is pushed into the heating block. This structure allows the heating of the workpiece to be continuous, and there is no need to cyclically open the cover plate to add the workpiece, which also reduces heat loss.

[0028] 4. The present invention is equipped with sensors, card blocks and inclined blocks. When the cover is closed, the fixed block is embedded in the card block. The sensor detects the temperature of the feeding area of the furnace body in real time and displays it on the display screen. When the temperature rises, the No. 4 motor rotates to drive the threaded rod to rotate, and the rotation of the threaded rod drives the transmission plate to move. The movement of the transmission plate drives the push plate to move, and the movement of the push plate drives the inclined block to move. The movement of the inclined block drives the card block to move, and the card block moves and is inserted into the card slot, so that the cover is locked. This locking structure is controlled by the sensor. When the temperature is high, the cover is locked through this structure, thereby avoiding the cover from being accidentally opened and causing burns, thereby greatly improving safety.

One end of the other group of air pipes 10 is installed with an air outlet plate 11, and the bottom of the air outlet plate 11 is connected to the top of the heating block 7. The gas burner assembly sprays flames, so that the heat transfer plate 6 is heated by the flames. The heat transfer plate 6 transfers heat to the heating block 7, making the heating block 7 a heat storage heating area. Inert gas is stored in the gas storage tank 8. Before heating, the air pump 9 sprays the inert gas through the air pipes 10 from the air outlet plate 11, so that the inert gas replaces the oxygen-containing air, and the inert gas fills the furnace body 1. This structure separates the oxidation-reduction reaction at the flame from the heating area, and through the protection of the inert gas, the workpiece 40 is not easily oxidized during heating, thereby improving the heating effect;

A heat transfer plate 20 is installed through the inner wall of a group of heat insulating plates 18. When heating, the spring 19 pops the heat insulating plate 18 out of the groove 16, so that the heating area is separated from the feeding area and the discharging area, so that the processing area The heat in the area is quickly accumulated, which reduces the heat dissipation. After the heating is completed, the No. 1 motor 13 rotates to drive the reel 14 to rotate. The reel 14 rotates to wind the pull rope 15. The pull rope 15 pulls the connecting plate 17 to move.

When heating, its spring 19 pops the heat insulation plate 18 out of the groove 16, so that the heating area is separated from the feeding area and the discharging area, so that the heat in the processing area can be quickly accumulated The heat dissipation is reduced. After the heating is completed, the No. 1 motor 13 rotates to drive the reel 14 to rotate. The reel 14 rotates to wind the pull rope 15. The pull rope 15 pulls the connecting plate 17 to move. The movement of the connecting plate 17 drives the heat insulation plate 18 to move, so that the heat insulation plate 18 can be retracted into the groove 16, thereby not affecting the movement of the workpiece 40. The heat insulation plate 18 on the feeding side is installed with a heat transfer plate 20, so that part of the heat in the heating area is transferred to the workpiece 40 on the feeding side through the heat transfer plate 20, so that the workpiece 40 can be preheated. When the preheated workpiece 40 enters the processing area for heating again, its heating efficiency is improved, thereby reducing the high-power heating time in the processing area, thereby achieving energy saving.

[0045] The outer wall of the cover plate 21 is provided with a card slot 30. The outer wall of the furnace body 1 is installed with a fixing block 31. The inner wall of the fixing block 31 is installed with a fourth motor 32. The output end of the fourth motor 32 is installed with a threaded rod 33. The outer wall of the threaded rod 33 is installed with a transmission plate 34. The outer wall of the transmission plate 34 is installed with a push plate 35. The inner wall of the fixing block 31 is installed with an inclined block 36. The outer wall of the inclined block 36 is installed with a clamping block 37. The outer wall of the cover plate 21 is installed with a sensor 38. The outer wall of the cover plate 21 is installed with a display screen 39. The inner bottom wall of the furnace body 1 is installed with a workpiece 40. When the cover plate 21 is closed, the fixing block 31 is embedded into the clamping block 37. The sensor 38 detects the temperature of the feeding area of the furnace body 1 in real time and displays it on the display screen 39. When the temperature rises, the fourth motor 32 rotates to drive the threaded rod 33 to rotate. The threaded rod 33 rotates to drive the transmission plate 34 to move. The transmission plate 34 moves to drive the push plate 35 to move. The push plate 35 moves to push the inclined block 36 to move. The inclined block 36 moves to drive the clamping block 37 to move. The clamping block 37 moves and inserts into the card slot 30, so that the cover plate 21 is locked. This locking structure is controlled by the sensor 38. When the temperature is relatively high, the cover plate 21 is locked through this structure, thus avoiding the situation that the cover plate 21 is accidentally opened and causing scalding, greatly improving the safety.

[0046] The working steps of this heating furnace are as follows:

[0047] S1. Its gas burner assembly sprays out flames, making the heat transfer plate 6 be baked and heated by the flames. The heat transfer plate 6 transfers the heat to the heating block 7, making the heating block 7 be the regenerative heating area. An inert gas is stored in the gas storage tank 8. Before heating, the air pump 9 sprays the inert gas from the air outlet plate 11 through the air pipe 10, making the inert gas replace the oxygen-containing air and filling the inert gas in the furnace body 1. This structure separates the oxidation-reduction reaction at the flame from the heating area, and through the protection of the inert gas, the workpiece 40 is not prone to oxidation reaction during heating, thus improving the heating effect.

[0048] S2. During heating, its spring 19 pops the heat insulation plate 18 out of the groove 16, separating the heating area from the feeding area and the discharging area, enabling the heat in the processing area to gather quickly and reducing the heat dissipation. After heating, the first motor 13 rotates to drive the reel 14 to rotate. The reel 14 rotates to wind the pull rope 15. The pull rope 15 pulls the connecting plate 17 to move. The connecting plate 17 moves to drive the heat insulation plate 18 to move, enabling the heat insulation plate 18 to retract into the groove 16, thus not affecting the movement of the workpiece 40. And the heat insulation plate 18 on the feeding side is installed with a heat transfer piece 20, enabling part of the heat in the heating area to be transferred to the workpiece 40 on the feeding side through the heat transfer piece 20, so that the workpiece 40 is preheated. When the preheated workpiece 40 enters the processing area for heating, its heating efficiency is improved, and further the high-power heating time in the processing area is reduced, thus achieving energy conservation.

[0049] When the workpiece 40 in the heating block 7 finishes heating and it is necessary to heat the next workpiece 40, the second motor 23 rotates to drive the gear 24 to rotate. The rotation of the gear 24 drives the toothed plate 25 to move. The movement of the toothed plate 25 moves the adjusting plate 26 into the heating block 7. Subsequently, the third motor 27 rotates to drive the screw 28 to rotate. The rotation of the screw 28 drives the telescopic plate 29 to move, causing the telescopic plate 29 to move to one side of the workpiece 40. Subsequently, the adjusting plate 26 moves to push the workpiece 40 out of the processing area. Then, using this structure, the workpiece 40 in the feeding area is pushed into the heating block 7. This structure enables the continuous heating of the workpiece 40, eliminating the need to repeatedly open the cover plate 21 to add the workpiece 40 and reducing heat loss.

[0050] When the cover plate 21 is closed, the fixed block 31 is inserted into the clamping block 37. The sensor 38 continuously detects the temperature in the feeding area of the furnace body 1 and displays it on the display screen 39. When the temperature rises, the fourth motor 32 rotates to drive the threaded rod 33 to rotate. The rotation of the threaded rod 33 drives the transmission plate 34 to move. The movement of the transmission plate 34 drives the push plate 35 to move. The movement of the push plate 35 pushes the inclined block 36 to move. The movement of the inclined block 36 drives the clamping block 37 to move. The movement of the clamping block 37 is inserted into the card slot 30, thereby locking the cover plate 21. This locking structure is controlled by the sensor 38. When the temperature is relatively high, the cover plate 21 is locked through this structure, thus avoiding the situation of accidental opening of the cover plate 21 and causing scalding, greatly improving safety.

[0051] Working principle: The gas burner assembly sprays flames, causing the heat transfer plate 6 to be baked and heated by the flames. The heat transfer plate 6 transfers heat to the heating block 7, making the heating block 7 the regenerative heating area. An inert gas is stored in the gas storage tank 8. Before heating, the air pump 9 sprays the inert gas from the air outlet plate 11 through the air pipe 10, replacing the oxygen-containing air with the inert gas and filling the inert gas in the furnace body 1. This structure separates the oxidation-reduction reaction at the flame from the heating area, and with the protection of the inert gas, the workpiece 40 is not easily oxidized during heating, thus improving the heating effect. During heating, the spring 19 ejects the heat insulation plate 18 from the groove 16, separating the heating area from the feeding area and the discharging area, enabling the heat in the processing area to quickly accumulate and reducing heat dissipation. After heating, the first motor 13 rotates to drive the reel 14 to rotate. The reel 14 rotates to wind the pull rope 15, and the pull rope 15 pulls the connecting plate 17 to move. The connecting plate 17 moves to drive the heat insulation plate 18 to move, allowing the heat insulation plate 18 to retract into the groove 16, thus not affecting the movement of the workpiece 40. Moreover, the heat insulation plate 18 on the feeding side is equipped with heat transfer fins 20, enabling part of the heat in the heating area to be transferred to the workpiece 40 on the feeding side through the heat transfer fins 20, thereby preheating the workpiece 40. When the preheated workpiece 40 enters the processing area for heating, its heating efficiency is improved, reducing the high-power heating time in the processing area, thus achieving energy conservation. When the workpiece 40 in the heating block 7 has completed heating and it is necessary to heat the next workpiece 40, the second motor 23 rotates to drive the gear 24 to rotate. The gear 24 rotates to drive the toothed plate 25 to move. The toothed plate 25 moves to move the adjusting plate 26 into the heating block 7. Subsequently, the third motor 27 rotates to drive the screw 28 to rotate. The rotation of the screw 28 drives the telescopic plate 29 to move, causing the telescopic plate 29 to move to one side of the workpiece 40. Then the adjusting plate 26 moves to push the workpiece 40 out of the processing area. Subsequently, the workpiece 40 in the feeding area is pushed into the heating block 7 using this structure. This structure enables the continuous heating of the workpiece 40, eliminating the need to repeatedly open the cover plate 21 to add the workpiece 40 and reducing heat loss. When the cover plate 21 is closed, the fixed block 31 is inserted into the clamping block 37. The sensor 38 continuously detects the temperature in the feeding area of the furnace body 1 and displays it on the display screen 39. When the temperature rises, the fourth motor 32 rotates to drive the threaded rod 33 to rotate. The threaded rod 33 rotates to drive the transmission plate 34 to move. The transmission plate 34 moves to drive the push plate 35 to move. The push plate 35 moves to push the inclined block 36 to move. The inclined block 36 moves to drive the clamping block 37 to move. The clamping block 37 moves to insert into the card slot 30, thereby locking the cover plate 21. This locking structure is controlled by the sensor 38. When the temperature is relatively high, the cover plate 21 is locked through this structure, thus preventing the cover plate 21 from being accidentally opened and causing scalding, greatly improving safety.
