[0031] In order to make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments.

[0032] Please refer to Figures 1 to 6 As shown, in an embodiment of the present utility model, in a first aspect, an open cover device is provided, which includes a main cover body 1 and a linear drive unit 2. The main cover body 1 is used to cover the upper part of the furnace body, and the main cover body 1 is hinged to the furnace body. The linear drive unit 2 has a body part and a drive end. The body part of the linear drive unit 2 is used to be hinged to the furnace body, and the drive end is hinged to the main cover body 1. The linear drive unit 2 is used to drive the main cover body 1 to rotate around the hinge axis to realize the opening or closing of the main cover body 1.

[0033] Specifically, the main cover body 1 refers to a component with a certain area, and the main cover body 1 can be a block, a plate, or a combination of multiple shapes. Articulation means that two components are connected and can rotate relative to each other around the hinge axis, and the two components are connected by hinges or hinges. The linear drive unit 2 refers to a component that can drive an object to move in a straight line, and the linear drive unit 2 can be a drive cylinder, an electric push rod, or a hydraulic cylinder.

[0034] The cover opening device provided by the embodiment of the utility model is provided with a main cover body 1 on the upper part of the furnace body, and the heat in the furnace body can be prevented from being dissipated through the main cover body 1, and at least part of the main cover body 1 is hinged to the furnace body, so that the main cover body 1 can rotate around the hinge axis. At the same time, a linear drive unit 2 is provided between the furnace body and the main cover body 1, and the main body of the linear drive unit 2 is used to be hinged on the furnace body and the driving end is hinged on the main cover body 1, and the linear drive unit 2 is used to drive the main cover body 1 to rotate around the hinge axis to realize the opening or closing of the main cover body 1. Compared with the cover opening device in the prior art, when the main cover body 1 needs to be opened or closed, the linear drive unit 2 can be used to drive the main cover body 1 to rotate around the hinge axis to realize the opening or closing of the main cover body 1. At the same time, the main body of the linear drive unit 2 is hinged on the furnace body and the driving end is hinged on the main cover body 1, so that the linear drive unit 2 can adjust its own posture and inclination angle as the main cover body 1 is flipped, thereby making the opening and closing operations of the main cover body 1 more convenient and quick, and making the inspection, debugging and maintenance of the heating furnace more convenient.

[0035] In an alternative embodiment, see Figure 1 A first articulated structure 3 is arranged between the main body of the linear drive unit 2 and the furnace body. The first articulated structure 3 includes an articulated support installed on the furnace body, an articulated component arranged on the main body of the linear drive unit 2, and a rotating shaft body that passes through the articulated support and the articulated component. The articulated support and the articulated component are both rotatably connected to the rotating shaft body.

[0036] In one embodiment, see Figure 1 , the number of the linear drive units 2 is multiple, and the multiple linear drive units 2 are arranged at intervals in a direction parallel to the hinge axis. Specifically, by arranging multiple linear drive units 2 to drive the main cover body 1 at the same time, the flipping of the main cover body 1 can be made more convenient. At the same time, the multiple linear drive units 2 are arranged at intervals in a direction parallel to the hinge axis, so that the main cover body 1 can be more evenly stressed in a direction parallel to the hinge axis, thereby preventing the main cover body 1 from being deformed during the flipping process.

[0037] In an alternative embodiment, see Figure 1, the linear drive unit 2 includes a drive cylinder. Specifically, a drive cylinder refers to a component that converts the energy of compressed gas into linear motion. A drive cylinder usually consists of a pressure chamber, a piston, and a piston rod assembly. Among them, the end of the piston rod is usually used as the drive end of the drive cylinder. When the drive cylinder works, it usually needs to be connected to a drive gas circuit composed of pipelines and control valves. The compressed gas entering the drive cylinder can be controlled through the control valve to change the motion state of the drive cylinder. By adopting the drive cylinder method, the linear drive unit 2 can keep the compressed gas in the drive cylinder unchanged by closing the control valve during the working process of the drive cylinder, so that the motion state of the drive cylinder itself can be maintained unchanged for a long time. Furthermore, the main cover 1 can stay at a certain position unchanged for a long time, and will not suddenly close due to the failure of the drive cylinder caused by sudden situations such as power failure, making the opening and closing of the main cover 1 safer.

[0038] In one embodiment, please refer to Figure 1 and Figure 3 , the main cover 1 has an installation end and a free end arranged oppositely. The installation end is used for hinging to the furnace body. A turning member 5 is arranged on the main cover 1. The first end of the turning member 5 is connected to the main cover 1, and the second end of the turning member 5 protrudes from the installation end. The drive end of the linear drive unit 2 is hinged to the second end of the turning member 5. Specifically, the installation end and the free end refer to two oppositely arranged ends on the main cover 1. The installation end and the free end can be two ends oppositely arranged along the direction parallel to the hinge axis, or two ends oppositely arranged along the direction perpendicular to the hinge axis. The turning member 5 refers to a component with a certain length. The turning member 5 can be columnar, rod-shaped, or strip-shaped, etc. The first end of the turning member 5 can be fixed to the main cover 1 by welding, fastener connection, or snap connection. At the same time, by extending the second end of the turning member 5 to protrude from the installation end of the main cover 1 and hinging the drive end of the linear drive unit 2 to the second end of the turning member 5, the main cover 1 can be driven to rotate around the hinge axis by the linear drive unit 2 through the lever action of the turning member 5 at this time, so that the free end of the main cover 1 can move away from or close to the furnace body along an arc trajectory to realize the opening and closing of the main cover 1. By hinging the installation end to the furnace body, and at the same time by setting a turning member 5 with a certain length, making the second end of the turning member 5 protrude from the installation end, and hinging the drive end of the linear drive unit 2 to the second end of the turning member 5, it is more labor-saving for the linear drive unit 2 to drive the main cover 1 to rotate. In addition, when the linear drive unit 2 drives the main cover 1 to turn over, the linear drive unit 2 can be far away from the free end of the main cover 1, avoiding the linear drive unit 2 blocking at the opening after the main cover 1 is opened, which causes obstruction to the maintenance, debugging, and maintenance of the furnace body, making the use of the entire cover opening device more convenient.

[0039] In an alternative embodiment, see Figure 1 A second hinge structure 4 is arranged between the mounting end of the main cover body 1 and the furnace body. The second hinge structure 4 includes a first hinge block arranged on the mounting end of the main cover body 1, a second hinge block arranged on the furnace body, and a rotating shaft body that runs through the first hinge block and the second hinge block at the same time, and the first hinge block and the second hinge block are both rotatably connected to the rotating shaft body.

[0040] In one embodiment, see Figure 1 and Figure 3 An extension rod 6 is provided between the driving end of the linear drive unit 2 and the second end of the flip member 5, one end of the extension rod 6 is connected to the driving end of the linear drive unit 2, and the other end of the extension rod 6 is hinged to the second end of the flip member 5 through a joint bearing 7. Specifically, the extension rod 6 refers to a component with a certain length, and the extension rod 6 can be columnar, rod-shaped or strip-shaped. The joint bearing 7 refers to a spherical sliding bearing, whose sliding contact surface consists of an inner spherical surface and an outer spherical surface, so that the bearing can rotate and swing at any angle during movement. By providing an extension rod 6 between the driving end of the linear drive unit 2 and the second end of the flip member 5, and one end of the extension rod 6 is connected to the driving end of the linear drive unit 2, and the other end of the extension rod 6 is hinged to the second end of the flip member 5 through a joint bearing 7, the length of the extension rod 6 can be selected according to the position of the linear drive unit 2, so that the position setting of the linear drive unit 2 is more flexible, and the installation of the linear drive unit 2 is also more convenient.

[0041] In one embodiment, see Figure 2 The furnace body 15 is also provided with a clamping clamp 8 for clamping and fixing the free end to the furnace body, and the free end of the main cover body 1 is provided with a clamping piece 9 for cooperating with the clamping clamp 8, and the clamping piece 9 is arranged protruding from the free end. Specifically, the clamping clamp 8 refers to a tool or component for fixing, clamping or clamping a workpiece, and the clamping piece 9 refers to a component with a certain volume, and the clamping piece 9 can be block-shaped, plate-shaped or column-shaped. By arranging the clamping piece 9 to protrude from the free end, the clamping clamp 8 can be used to clamp the top surface of the clamping piece 9 after the main cover body 1 is closed, so as to avoid a gap between the main cover body 1 and the furnace body after the cover is closed, thereby making the main cover body 1 close more tightly and safely.

[0042] In an alternative embodiment, see Figure 2, the pressing clamp 8 includes a pressing base, a clamp part hinged to the pressing base, and a driving handle part for driving the movement of the clamp part. The driving handle part is hinged to both the clamp part and the pressing base. Specifically, the pressing base refers to a supporting component with a certain height, and both the driving handle part and the clamp part refer to components with a certain length. One end of the clamp part is hinged to the pressing base, and the other end of the clamp part is used to press an object. One end of the driving handle part is hinged to the pressing base, and the middle part of the driving handle part is hinged to the middle part of the clamp part. By pulling the second end of the driving handle part, the driving of the clamp part can be realized, making the use of the pressing clamp 8 more convenient.

[0043] In an alternative embodiment, please refer to Figure 2 , a pushing handle 11 may also be provided at the free end of the main cover body 1. Specifically, the pushing handle 11 refers to a component that can be held by an operator. By providing the pushing handle 11 at the free end of the main cover body 1, when the linear drive unit 2 cannot work, the operator can open or close the main cover body 1 through the pushing handle 11.

[0044] In an embodiment, please refer to Figure 3 and Figure 4 , a gas supply structure 12 is provided on the main cover body 1, and the gas supply structure 12 is used to communicate with an external gas source pipeline to supply a protective gas to the inside of the furnace body. Specifically, the gas supply structure 12 refers to a structure that can output a protective gas. The gas supply structure 12 is usually connected to an external gas source. Through the gas supply structure 12, inert gases such as nitrogen, argon, or helium can be input into the furnace body when the main cover body 1 is closed, thereby protecting the products in the heating furnace and preventing the products from undergoing adverse changes such as oxidation due to high temperature, making the use of the heating furnace safer and ensuring the quality of the products.

[0045] In an alternative embodiment, please refer to Figure 5 , the gas supply structure 12 includes a gas supply component 121. The gas supply component 121 and the main cover body 1 enclose a gas supply cavity 122. The gas supply cavity 122 can communicate with an external gas source pipeline. A plurality of gas supply holes 123 may be provided on the main cover body 1, and all the plurality of gas supply holes 123 communicate with the gas supply cavity 122. During operation, a protective gas can be introduced into the gas supply cavity 122, and then the protective gas can be evenly supplied into the furnace body through the gas supply holes 123 through the main cover body 1.

[0046] In an embodiment, please refer to Figure 3 and Figure 4, a heating unit 13 is provided on the main cover body 1. The outlet of the heating unit 13 is connected to the gas supply structure 12 through a pipeline, and the inlet of the heating unit 13 is connected to an external gas source pipeline. The heating unit 13 is used to heat the protective gas entering the furnace body. Specifically, the heating unit 13 refers to a component that can heat the gas. By providing the heating unit 13 on the main cover body 1, the protective gas entering the furnace body can be heated, avoiding the influence of the relatively low-temperature protective gas on the heating effect of the furnace body after entering the furnace body, improving the heating effect of the heating furnace, and ensuring the quality of the product.

[0047] In an alternative embodiment, please refer to Figure 6 , the heating unit 13 includes a heating block 131 and an electric heating rod 132 provided on the heating block 131. The heating block 131 is generally made of a material with relatively high thermal conductivity such as metal. The electric heating rod 132 refers to a component that converts electrical energy into heat energy. An installation hole for installing the electric heating rod 132 is provided on the heating block 131.

[0048] In an embodiment, please refer to Figure 3 and Figure 4 , a ventilation unit 14 is provided on the main cover body 1. The air outlet of the ventilation unit 14 is used to be connected to an oil fume collector through a pipeline, and the oil fume collector is used to extract and collect the oil fume generated in the furnace body through the ventilation unit 14. Specifically, the ventilation unit 14 refers to a component or assembly that can extract the oil fume in the furnace body. The ventilation unit 14 can extract the oil fume by generating negative pressure through the oil fume collector, or the ventilation unit 14 can also generate negative pressure to extract the oil fume by providing a negative pressure generating unit on the pipeline between the oil fume collector and the ventilation unit 14. By providing the ventilation unit 14 on the main cover body 1 and connecting it to the oil fume collector pipeline, during the operation of the heating furnace, the oil fume generated by the heating furnace can be extracted and collected for treatment, making the operation of the heating furnace more environmentally friendly and clean.
