[0030] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0031] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a variety of structural modes and implementation modes that can be replaced by those skilled in the art can be replaced with each other. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as the whole of the present invention or as a limitation or restriction to the technical solution of the invention.

[0032] The directional terms such as up, down, left, right, front, back, front, back, top, bottom, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. They are relative concepts and may change accordingly according to different positions and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0033] like Figure 1-3 As shown, a heating furnace 10 provided by an embodiment of the present invention includes a furnace body 1, and the furnace body 1 is provided with an air inlet channel 11 and an air exhaust channel 12. A cylinder multi-chamber heating furnace 10 includes a furnace body 1, a heater 2 and a fan 3, and the furnace body 1 is provided with an air inlet channel 11, an air exhaust channel 12 and a connecting channel 13.

[0034] The air inlet channel 11 and the air exhaust channel 12 are arranged in parallel and at intervals, and the air exhaust channel 12 is communicated with the outside of the furnace body 1 .

[0035] A plurality of heating chambers 4 connected in parallel are arranged in the furnace body 1 , and the plurality of heating chambers 4 are located between the air inlet channel 11 and the air exhaust channel 12 .

[0036] Each of the plurality of heating bins 4 is provided with a bin air inlet 41 and a bin air outlet 42 . The bin air inlet 41 is connected to the air inlet channel 11 , and the bin air outlet 42 is connected to the exhaust channel 12 .

[0037] The heating furnace 10 is mainly used to heat the mold, and of course, it can also heat other workpieces. The heating furnace 10 includes a furnace body 1, which is the main body of the heating furnace 10. The furnace body 1 is a furnace cavity, and the furnace cavity is provided with an air inlet channel 11 and an air exhaust channel 12. The air inlet channel 11 and the air exhaust channel 12 are arranged in parallel and extend in the up and down direction, and the air exhaust channel 12 is located on one side of the air inlet channel 11.

[0038] The plurality of heating chambers 4 are arranged in the vertical direction and are located between the air inlet channel 11 and the air outlet channel 12. Each heating chamber 4 has a chamber cavity, a chamber air inlet hole 41 and a chamber air outlet hole 42. The chamber cavity of each heating chamber 4 is connected to the air inlet channel 11 through the chamber air inlet hole 41 and is connected to the air outlet channel 12 through the chamber air outlet hole 42. In this way, the plurality of heating chambers 4 are connected in parallel, and any two heating chambers 4 are not connected.

[0039] When the heating furnace 10 is in use, hot air enters the air inlet channel 11, then enters the chamber cavity through the chamber air inlet hole 41, and then enters the exhaust channel 12 through the chamber air outlet hole 42. After entering each heating chamber 4, the hot air in the air inlet channel 11 directly enters the exhaust channel 12 for discharge, thus changing the previous method of hot air entering one heating chamber 4 and then entering the next heating chamber 4. Each heating chamber 4 in the heating furnace 10 is in an independent heating state, and multiple heating chambers 4 do not transfer heat and interfere with each other, thereby facilitating the control of the temperature of each heating chamber 4 and maintaining the temperature of each heating chamber 4 consistent. In this way, the deformation amount of the heated objects in each heating chamber 4 can also remain consistent when deformed by heat, thereby ensuring product quality.

[0040] During the heating process, the gas flow path is that the gas outside the furnace body 1 first enters the air inlet channel 11, then passes through the heating chamber body 4 and enters the exhaust channel 12, and finally is discharged to the outside of the furnace body 1. The gas flow path is an external circulation, which not only reduces the impurities generated during heating, but also reduces the influence of the gas after passing through the heating chamber body 4 being heated and utilized again, so that it is easier to control the temperature of the heating chamber body 4.

[0041] Optionally, the heating furnace 10 is used in conjunction with an air supply device, which provides hot air flow to the heating furnace 10. The air supply end of the air supply device is connected to the air inlet channel 11. In other embodiments, a heating device is provided inside the heating furnace 10.

[0042] Optionally, a carrying platform is connected to the bottom of the furnace body 1 , and rollers are connected to the bottom of the carrying platform, so that the furnace body 1 can be moved conveniently.

[0043] In one embodiment, if Figure 1-2 As shown, when the heating furnace 10 is working, the angle between the flow direction of the airflow in the air inlet channel 11 and the flow direction of the airflow from the air inlet channel 11 into the air inlet hole 41 of the bin body is an acute angle.

[0044] Specifically, the hot air flow will flow to the warehouse air inlet hole 41 in the process of the air inlet channel 11, and enter the warehouse cavity from the warehouse air inlet hole 41. The direction of the air flow along the extension direction of the air inlet channel is the first flow direction, and the direction of the air flow toward the warehouse air inlet hole 41 is the second flow direction. The angle between the first flow direction and the second flow direction is an acute angle. In this way, the air flow in the air inlet channel 11 can flow smoothly to the warehouse air inlet hole 41, reducing the length of the path for the air flow to enter the warehouse cavity.

[0045] In one embodiment, if Figure 2 As shown, the air inlet 41 of the storage body is located above the air outlet 42 of the storage body, so that the air flow in the heating storage body 4 flows from top to bottom.

[0046] Specifically, the air inlet channel 11 extends up and down, and the airflow flows from top to bottom. The air inlet hole 41 of the warehouse body is located above the air outlet hole 42 of the warehouse body. After the airflow enters from the air inlet hole 41 of the warehouse body, it is discharged from the air outlet hole 42 of the warehouse body, and the airflow also flows from top to bottom. The density of the hot air flow is smaller than that of air, and it flows passively from top to bottom, which increases the flow rate. Therefore, the cold air inside can be quickly discharged and heated quickly. Moreover, the airflow flows from top to bottom, which reduces the length of the path of the airflow entering the heating warehouse body 4, thereby reducing the heat loss during the flow process and further improving the heating efficiency.

[0047] Optionally, the warehouse air inlet 41 is arranged on the warehouse top wall of the heating warehouse 4, and the warehouse air outlet 42 is arranged on the warehouse bottom wall of the heating warehouse 4. In other embodiments, the warehouse air inlet 41 is arranged on the warehouse side wall of the heating warehouse 4 facing the air inlet channel 11, and the warehouse air outlet 42 is arranged on the warehouse side wall of the heating warehouse 4 facing the exhaust channel 12.

[0048] In one embodiment, if Figure 1-3 As shown, an air inlet hole 14 is provided on the furnace body 1 , and the air inlet hole 14 is communicated with the exhaust passage 12 .

[0049] Specifically, the air inlet 14 is provided on the side wall of the furnace body 1, and is used to add new gas into the furnace body 1. The gas exhausted from the heated warehouse body 4 enters into the exhaust passage 12, and the gas flow in the exhaust passage 12 generates low pressure, so that the gas outside the furnace body 1 enters into the exhaust passage 12 from the air inlet 14, thereby reducing the content of the gas exhausted from the heated warehouse body 4.

[0050] In one embodiment, if Figure 1-3 As shown, an exhaust pump 5 is connected to the furnace body 1 , and the exhaust passage 12 is communicated with the outside of the furnace body 1 through the exhaust pump 5 .

[0051] Specifically, the heating furnace 10 further includes an exhaust pump 5, the air pump inlet of the exhaust pump 5 is connected to the exhaust passage 12, and the air pump outlet of the exhaust pump 5 is connected to the outside of the furnace body 1. During heating, the gas flows in the air inlet hole 14, and then a part of the gas is sucked into the air inlet passage 11 by the fan 3 through the connecting passage 13, and the other part is sucked out to the outside of the furnace body 1 by the exhaust pump 5. The exhaust pump 5 improves the efficiency of gas exhaust.

[0052] In one embodiment, if Figure 1-2As shown, a plurality of heating silos 4 are arranged at intervals, and a partition 6 is arranged between any two adjacent heating silos 4. The partition 6 is connected between the silo air outlet 42 of one heating silo 4 and the silo air inlet 41 of another heating silo 4, and the partition 6 is used to guide the wind in the air inlet channel 11 to enter the silo air inlet 41, and guide the wind discharged from the silo air outlet 42 of the heating silo 4 to enter the exhaust channel 12. Specifically, the heating silo 4 is arranged between the air inlet channel 11 and the exhaust channel 12. The silo air inlet 41 is arranged at the upper end of the heating silo 4, and the silo air outlet 42 is arranged at the lower end of the heating silo 4. Two adjacent heating silos 4 are spaced apart by a distance in the up-down direction, and a partition 6 is connected between the two adjacent heating silos 4, the upper end of the partition 6 is connected to the silo bottom wall of the upper heating silo 4, and the lower end of the partition 6 is connected to the silo top wall of the lower heating silo 4. The partition 6 blocks the connection between the body air outlet 42 of the upper heating body 4 and the body air inlet 41 of the lower heating body 4, so that the body air outlet 42 is only connected to the exhaust passage 12, and the body air inlet 41 is only connected to the air inlet passage 11. In this way, two adjacent heating bodies 4 are not in contact with each other, so that heat conduction between the two adjacent heating bodies 4 through the contacting body walls is avoided.

[0053] In one embodiment, if Figure 2 As shown, the partition 6 is inclined. Such a configuration is conducive to guiding the gas flow. Specifically, the partition 6 is horizontally inclined downward, one end of the partition 6 is connected to the bottom wall of the heating bin 4 located above, and the other end of the partition 6 is connected to the top wall of the heating bin 4 located below. The partition 6 divides the space between two adjacent heating bins 4 into an air inlet guide channel and an air exhaust guide channel.

[0054] The air inlet guide channel is connected to the air inlet channel 11, and has a first channel end close to the air inlet channel 11 and a second channel end away from the air inlet channel 11, and the width of the first channel end is greater than the width of the second channel end. The hot air in the air inlet channel 11 flows from the first channel end to the second channel end. In this way, the air volume entering the heating chamber 4 per unit time is increased.

[0055] The exhaust guide channel is connected to the exhaust channel 12, and the exhaust guide channel has a third channel end close to the exhaust channel 12 and a fourth channel end away from the exhaust channel 12, and the width of the third channel end is greater than the width of the fourth channel end. The gas exhausted from the heating chamber 4 flows from the fourth channel end to the third channel end. In this way, the air volume entering the exhaust channel 12 per unit time is increased.

[0056] In one embodiment, if Figure 1-2 and Fig. 9As shown, the heating furnace 10 further includes a heater 2 and a fan 3, and a connecting channel 13 is provided in the furnace body 1. One end of the connecting channel 13 is connected to the exhaust channel 12, and the other end is connected to the air inlet channel 11 through the fan 3, and the heater 2 is located in the connecting channel 13.

[0057] Specifically, an air inlet channel 11, an air exhaust channel 12 and a connecting channel 13 are arranged in the furnace body cavity, and the air inlet channel 11 and the air exhaust channel 12 are arranged at intervals and extend in the up-down direction. The connecting channel 13 is located between the air inlet channel 11 and the air exhaust channel 12, and the fan 3 is located between the connecting channel 13 and the air inlet channel 11, wherein one end of the connecting channel 13 is connected to the air exhaust channel 12, and the other end is connected to the fan inlet of the fan 3, and the fan outlet of the fan 3 is connected to the air inlet channel 11. The exhaust channel 12 is connected to the outside of the furnace body 1, so that the gas outside the furnace body 1 can enter the furnace body 1, and the gas inside the furnace body 1 can also be discharged to the outside of the furnace body 1.

[0058] When the heating furnace 10 is in use, the hot air heated by the heater 2 is discharged into the air inlet channel 11 through the fan 3, enters the chamber cavity through the chamber air inlet hole 41, and then enters the exhaust channel 12 through the chamber air outlet hole 42. In this way, the heating furnace 10 has the function of heating and generating hot air, and is convenient to use.

[0059] Optionally, a furnace body through hole is provided on the furnace body 1, and the connecting channel 13 and the exhaust channel 12 are respectively connected to the furnace body through hole. In this way, the gas outside the furnace body 1 enters from the furnace body through hole and enters the air inlet channel 11 through the connecting channel 13. The gas inside the furnace body 1 is discharged from the furnace body through the exhaust channel 12 to the outside of the furnace body 1. The heater 2 is installed in the connecting channel 13, and the gas entering from the outside of the furnace body 1 is first heated by the heater 2 and then blown into the air inlet channel 11 by the fan 3.

[0060] Optionally, the heater 2 is a heating tube or a heating resistance wire, etc. The heater 2 is in the shape of a thermocouple convex point, which increases the contact area and improves the heating efficiency.

[0061] Optionally, two air inlet channels 11 and two connecting channels 13 are provided in the furnace body 1, the exhaust channel 12 is located between the two air inlet channels 11, and a heater 2 and a fan 3 are provided on the two connecting channels 13. Multiple heating chambers 4 are provided in parallel between the exhaust channel 12 and each air inlet channel 11. Such an arrangement improves production efficiency.

[0062] In one embodiment, if Figure 2 As shown, a thermometer 7 is provided in each heating bin body 4. The thermometer 7 has a temperature measuring head, and the temperature measuring head extends into the heating bin body 4. The thermometer 7 is used to measure the temperature, so that the staff can understand the temperature in the heating bin body 4 at any time.

[0063] In one embodiment, if Figure 1-2 and Figure 4 As shown, a control mechanism 8 is provided on the furnace body 1 , and the control mechanism 8 includes a controller 81 , a regulator 82 for connecting to the heater 2 , and a converter 83 for connecting to the temperature measuring device 7 .

[0064] The converter 83 is connected to the controller 81 for communication, and the regulator 82 is connected to the controller 81 for communication.

[0065] Specifically, the heating furnace 10 also includes a control mechanism 8, which includes a controller 81, a regulator 82 and a converter 83. A control unit 811 and a judgment unit 812 electrically connected to the control unit 811 are provided in the controller 81. The converter 83 is connected to the judgment unit 812 in communication, and the thermometer 7 is connected to the converter 83 in communication. The regulator 82 is connected to the control unit 811 in communication, and the heater 2 is connected to the regulator 82 in communication. The judgment unit 812 is provided with a preset temperature value, the thermometer 7 monitors the temperature of the heating bin 4 in real time, and the converter 83 converts the temperature measured by the thermometer 7 into an electrical signal and transmits it to the judgment unit 812. The judgment unit 812 compares the measured temperature value with the preset temperature value, and then transmits the compared information to the control unit 811. The control unit 811 controls the regulator 82 to adjust the power according to the information transmitted by the judgment unit 812, and adjusts the heating temperature of the heater 2. In this way, the temperature of the heating bin 4 is automatically controlled, the automation is improved, and the temperature of the heating bin 4 is adjusted more quickly and accurately, so that the temperature of the heating bin 4 is maintained at the preset value.

[0066] It should be noted that the above-mentioned communication connection refers to the ability to transmit information to each other, which can be achieved through wire connection or wireless methods such as WiFi.

[0067] In one embodiment, if Figure 2 and Figure 5-6 As shown, an air guide plate 9 is disposed in the air inlet hole 41 of the bin body, and a through hole 91 and a baffle 92 capable of covering the through hole 91 are disposed on the air guide plate 9, and the baffle 92 is slidably connected to the air guide plate 9.

[0068] Specifically, the air guide plate 9 extends toward the interior of the warehouse body, and the hot air enters the interior of the warehouse body along the air guide plate 9. A through hole 91 is provided on the air guide plate 9, and when the hot air flows along the air guide plate 9, it can also enter the interior of the warehouse body through the through hole 91, thereby increasing the amount of air intake. A slidable baffle plate 92 is connected to the air guide plate 9, which can be achieved by providing a slide rail or a slideway on the air guide plate 9. When the baffle plate 92 slides, the range of the baffle plate 92 blocking the through hole 91 can be adjusted, thereby adjusting the amount of air intake of the through hole 91.

[0069] Optionally, two air guide plates 9 are provided in the air inlet hole 41 of the bin body, and a funnel shape is formed between the two air guide plates 9 .

[0071] like Figure 1-8 The figure shows a heating furnace system provided by an embodiment of the present invention, comprising a loading and unloading device 20 and any one of the above-mentioned heating furnaces 10. The heating bin body 4 is provided with a bin door 43, and the bin door 43 is slidably connected to the side wall of the furnace body 1. The loading and unloading device 20 comprises a driving mechanism 201 for opening and closing the bin door 43 and a moving mechanism 202 for driving the driving mechanism 201 to move. The driving mechanism 201 comprises a mounting frame 2011, a connecting arm 2012 and a driver 2013. The mounting frame 2011 is connected to the moving output end of the moving mechanism 202, and the connecting arm 2012 is slidably connected to the mounting frame 2011 and connected to the bin door 43. The driver 2013 is installed and connected to the mounting frame 2011, and the driving output end of the driver 2013 is connected to the connecting arm 2012.

[0072] Specifically, the heating furnace system is composed of a loading and unloading device 20 and a heating furnace 10. For the specific structure and function of the heating furnace 10, please refer to the relevant content mentioned above, which will not be repeated here.

[0073] The loading and unloading device 20 is used to put the workpiece into the heating bin 4 and take the workpiece out of the heating bin 4. The loading and unloading device 20 controls the moving mechanism 202 and the driving mechanism 201. The moving mechanism 202 is used to drive the driving mechanism 201 to move up, down, left, and right. The driving mechanism 201 is used to open and close the bin door 43 of the heating bin 4. The loading and unloading device 20 can be a transplanter.

[0074] Optionally, the moving mechanism 202 includes a support seat, a lifting platform, a telescopic column and a sliding seat. The lifting platform is located above the support seat, and the telescopic column is connected between the lifting platforms. The lifting platform can be driven to move up and down by the telescopic column. The sliding seat is slidably connected to the lifting platform, and the driving mechanism 201 is connected to the sliding seat, and the driving mechanism 201 is driven to move left and right by the sliding seat. Of course, the moving mechanism 202 can also be other structures, as long as it can drive the driving mechanism 201 to move up and down and left and right.

[0075] The driving mechanism 201 includes a mounting frame 2011, a connecting arm 2012 and a driver 2013. The mounting frame 2011 is mounted on the moving mechanism 202, and the moving output end of the moving mechanism 202 drives the mounting frame 2011 to move. The connecting arm 2012 is slidably connected to the mounting frame 2011, and the driver 2013 is fixed to the mounting frame 2011. The driving output end of the driver 2013 is connected to the connecting arm 2012, and is used to drive the connecting arm 2012 to slide.

[0076] Optionally, the driver 2013 is a telescopic oil cylinder or a telescopic air cylinder.

[0077] In the heating furnace system configured in this way, the door 43 of the heating chamber 4 is opened and closed by the external driving mechanism 201, which reduces the need to set a structure for controlling the movement of the door 43 for each heating chamber 4, thereby simplifying the structure of the heating furnace 10 and saving costs. In addition, the influence of temperature on the driving mechanism 201 is reduced, and the driving mechanism 201 is less likely to be damaged.

[0078] In one embodiment, if Figure 7-8 As shown, two connecting plates 431 are arranged at intervals on the door 43, and a connecting groove is formed between the two connecting plates 431. A stopper 2014 extending toward the connecting groove is connected to the connecting arm 2012, and the stopper 2014 can be located in the connecting groove.

[0079] Specifically, two connecting plates 431 protruding outward are provided on the door 43, and the two connecting plates 431 are arranged at intervals, so that a connecting groove is formed between the two connecting plates 431. When the door 43 needs to be opened or closed, the moving mechanism 202 drives the driving mechanism 201 to move, so that the blocking block 2014 on the connecting arm 2012 extends into the connecting groove, and then the driver 2013 drives the connecting arm 2012 to slide, and the blocking block 2014 abuts against the connecting plate 431 to drive the door 43 to move.
