The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0025] See also Figure 1-6 The utility model provides a technical solution: a high-precision temperature-controlled industrial furnace with easy operation, including an industrial furnace body 1, a furnace door 2 is rotatably connected to the surface of the industrial furnace body 1, and the furnace mouth of the industrial furnace body 1 is closed to reduce heat loss. A placement plate 13 is slidably connected to the inside of the industrial furnace body 1 to provide a placement space for the workpiece to be heated. The movement of the placement plate 13 in the industrial furnace body 1 is a known technology to those skilled in the art, so it will not be discussed in detail here.

[0026] An L-shaped rack 9 is slidably connected to the upper side of the inner wall of the industrial furnace body 1, and a gear 7 is rotatably connected to the upper side of the inner wall of the industrial furnace body 1. The surface of the gear 7 is meshed with the surface of the rack 9. A spring 11 is fixedly connected to the surface of the rack 9. One end of the spring 11 away from the rack 9 is fixedly connected to the inner wall of the rack 9 for resetting the rack 9.

[0027] Furthermore, a first connecting rod 21 is fixedly connected to the surface of the gear 7, a second connecting rod 8 is rotatably connected to the side of the furnace door 2 close to the industrial furnace body 1, an end of the second connecting rod 8 away from the furnace door 2 is rotatably connected to an end of the first connecting rod 21 away from the gear 7, and the surface of the placement plate 13 is slidably connected to equidistantly arranged flip plates 12, the flip plates 12 are L-shaped, and the inside of the placement plate 13 is rotatably connected to a rotating rod 17 protruding from the surface of the placement plate 13, and the rotating rod 17 passes through the surface of the flip plate 12 and is fixedly connected to the inside of the flip plate 12.

[0028] A rotating groove 19 is provided on the inner wall of the industrial furnace body 1, and the inner wall of the rotating groove 19 is rotatably connected to a rotating shaft 16. The surface of a rotating rod 17 is slidably connected to the inside of the rotating shaft 16. A limiting bar 18 is fixedly connected to the surface of the rotating rod 17, and the surface of the limiting bar 18 is slidably connected to the inside of the rotating shaft 16. Therefore, through the setting of the limiting bar 18, when the rotating shaft 16 rotates, the rotating rod 17 can be smoothly driven to rotate, thereby smoothly driving the flip plate 12 to rotate on the placement plate 13, thereby ensuring the smooth operation of the device.

[0029] A worm wheel 15 is fixedly connected to the surface of the rotating shaft 16, and an operating shaft 3 protruding from the surface of the industrial furnace body 1 is rotatably connected to the surface of the industrial furnace body 1. A worm 14 is fixedly connected to the surface of the operating shaft 3, and the surface of the worm 14 is meshingly connected with the surface of the worm wheel 15. Therefore, by setting the worm wheel 15 and the worm 14, the position of the rotating shaft 16 can be restricted, thereby avoiding the arbitrary rotation of the rotating shaft 16 in the industrial furnace body 1, thereby facilitating the subsequent docking of the rotating shaft 16 with the rotating rod 17, and ensuring the smooth operation of the device.

[0030] One end of the operating shaft 3 protruding from the surface of the industrial furnace body 1 is fixedly connected with a handle, which makes it convenient for the staff to operate the operating shaft 3. Secondly, the surface of the operating shaft 3 is provided with carbon fiber cloth, which has the characteristics of high temperature resistance and non-heat conduction, thereby avoiding the situation where the staff is injured when operating the operating shaft 3, and reducing the safety hazard when using the device.

[0031] The cross-section of the rotating groove 19 is a 270-degree sector-shaped, and the cross-section of the rotating shaft 16 at one end inside the rotating groove 19 is a 180-degree sector-shaped. Therefore, by setting the rotating groove 19 and the sector-shaped rotating shaft 16, the rotation angle of the rotating shaft 16 can be limited, thereby facilitating the staff to determine the position of the rotating shaft 16, thereby improving the use effect of the device, facilitating the use of the device, and having high promotion value and practicality.

[0032] Furthermore, the surface of the industrial furnace body 1 is fixedly connected with a fuel inlet pipe 4 and a combustion-supporting gas inlet pipe 5 which penetrate the surface of the industrial furnace body 1, so as to respectively inject fuel and combustion-supporting gas into the industrial furnace body 1. A display screen 6 is arranged on the surface of the industrial furnace body 1, and a thermocouple 10 is arranged on the inner wall of the industrial furnace body 1. The thermocouple 10 is electrically connected to the display screen 6. Both the fuel inlet pipe 4 and the combustion-supporting gas inlet pipe 5 are provided with a solenoid valve 20, and the solenoid valve 20 is also electrically connected to the display screen 6. Through the setting of the solenoid valve 20, the thermocouple 10 and the display screen 6, the staff can understand the temperature in the industrial furnace body 1 through the thermocouple 10, and at the same time control the solenoid valve 20 through the thermocouple 10 to control the amount of injected fuel and combustion-supporting gas, thereby realizing accurate control of the temperature in the industrial furnace body 1.

[0033] Specifically, when in use, the workpiece is placed on the surface of the placement plate 13, and the workpiece is brought into contact with the end of the flip plate 12 that overlaps with the placement plate 13, and then the placement plate 13 is fed in until the placement plate 13 is located in the industrial furnace body 1. At this time, the placement plate 13 is in contact with the rack 9, and then the placement plate 13 is continued to be fed in, and then the placement plate 13 pushes the rack 9 and compresses the spring 11. The push of the placement plate 13 causes the rotating rod 17 on the placement plate 13 to be inserted into the rotating shaft 16, and the movement of the rack 9 drives the gear 7 to rotate, thereby driving the first connecting rod 21 to rotate, so that the position of the first connecting rod 21 changes, thereby The second connecting rod 8 is pulled, and then the furnace door 2 is pulled, so that the furnace door 2 and the industrial furnace body 1 rotate, and the furnace mouth of the industrial furnace body 1 is gradually closed. On the contrary, when the placement plate 13 is moved out, the rack 9 is driven to move in the opposite direction under the elastic force of the spring 11, thereby driving the furnace door 2 to open, so that the device can automatically close the furnace door 2 after the placement plate 13 is sent in, and can automatically open the furnace door 2 when the placement plate 13 slides out. No manual operation is required, which avoids the danger of personnel being in operation due to the high temperature in the furnace, is convenient for use by staff, and has high promotion value and practicality.

[0034] Secondly, after the workpiece is heated in the industrial furnace body 1 for a period of time, the staff can drive the worm 14 to rotate by rotating the operating shaft 3, thereby driving the worm wheel 15 to rotate, and driving the rotating rod 17 to rotate through the rotating shaft 16, thereby driving the flip plate 12 to flip in the placement plate 13, and then driving the workpiece to flip in the industrial furnace body 1, so that the side of the workpiece in contact with the placement plate 13 is no longer covered by the placement plate 13, so that the device can also heat the side of the workpiece covered by the placement plate 13, and then the staff can drive the workpiece to flip in the industrial furnace body 1 by rotating the operating shaft 3, so that the device can fully heat the workpiece, thereby improving the use effect of the device, avoiding the subsequent flipping of the workpiece and heating the workpiece again, thereby improving the efficiency of the device in heating the workpiece, improving the use effect of the device, and further improving the use effect and promotion value of the device.

[0035] Working principle: When in use, place the workpiece on the placement plate 13, and make the workpiece contact with one end of the flip plate 12, and then feed the placement plate 13 until the placement plate 13 is located in the industrial furnace body 1. At this time, the placement plate 13 contacts the rack 9, and then continue to feed the placement plate 13. The placement plate 13 pushes the rack 9 and compresses the spring 11, thereby driving the gear 7 to rotate, and then the position of the first connecting rod 21 changes, thereby pulling the second connecting rod 8 and pulling the furnace door 2, so that the furnace door 2 and the industrial furnace body 1 rotate, and gradually close the furnace mouth of the industrial furnace body 1. On the contrary, when the placement plate 13 moves, under the elastic force of the spring 11, the rack 9 is driven to move in the opposite direction, thereby driving the furnace door 2 to open.

[0036] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
