[0028] See also Figure 1 and Figure 2 , the driving mechanism 10 provided in the embodiment of the present application is now described. The driving mechanism 10 provided in the embodiment of the present application is used to drive the movable door body 202 of the processing equipment 20. Specifically, taking the door body 202 of the heating furnace 20 as an example, the driving mechanism 10 includes a driving member 101, an adapter 102, a first transmission member 103 and a guide wheel 104. The driving member 101 is arranged on the processing equipment 20; the adapter 102 is connected to the driving member 101 for driving, and the driving member 101 drives the adapter 102 to be movably arranged on the processing equipment 20; the first transmission member 103 is flexibly arranged, and the first transmission member 103 connects the connecting member and the door body 202; the guide wheel 104 is rotatably arranged on the processing equipment 20, and the first transmission member 103 can be bent and transmitted along the circumference of the guide wheel 104; the adapter 102 is driven by the driving member 101 to drive the first transmission member 103 to drive the door body 202 to move.

[0029] In the driving mechanism 10 provided in the embodiment of the present application, the driving member 101 drives the adapter 102 to move, and the adapter 102 drives the first transmission member 103 to move synchronously, and then the first transmission member 103 drives the door body 202 to move, thereby realizing drive control of the door body 202.

[0030] Among them, when the driving mechanism 10 of the embodiment of the present application is used to drive the door body 202 of the processing equipment 20, the flexible first transmission member 103 is arranged to cooperate with the guide wheel 104, which can be used to change the direction of the transmission force, that is, the driving member 101 can be arranged at a position away from the door body 202 or other side of the processing equipment 20, which can provide a larger space for the opening and closing of the door body 202, and help avoid interference.

[0031] Furthermore, the adapter 102 and the processing equipment 20 are movably connected, and the processing equipment 20 can play a stabilizing auxiliary role in the structure of the adapter 102. Using the adapter 102 as an intermediate connecting member between the driving member 101 and the first transmission member 103 can help the first transmission member 103 to achieve stable operation during the driving process, thereby also playing a stabilizing role in the driving of the door body 202.

[0032] The driving member 101 in the embodiment of the present application can be any driving source that meets the driving function, not limited to automatic drive or manual drive. Specifically, the embodiment of the present application takes the motor as an example. Compared with the cylinder, the motor drive can also be used normally in an environment with higher temperature.

[0033] In the embodiment of the present application, the adapter 102 is taken as an example in which the structural shape is fixed, and specifically the adapter 102 is taken as an example in which it is slidably connected to the processing equipment 20. A sliding connection of a slide rail and a slider can be adopted between the adapter 102 and the processing equipment 20 to improve the movement stability of the adapter 102.

[0034] The first transmission member 103 in the embodiment of the present application can be a rope-like structure or a chain. When the first transmission member 103 is a rope-like structure, the guide wheel 104 adopts a guide wheel structure with a smoother wheel rim; when the first transmission member 103 is a chain, the guide wheel 104 adopts a toothed sprocket structure, which can also be called a gear, so that the guide wheel 104 can mesh with the first transmission member 103. Specifically, in the embodiment of the present application, the first transmission member 103 is a metal chain and the guide wheel 104 is a sprocket. The chain and the sprocket have high matching accuracy and the bending direction of the chain is controllable, which helps to prevent the door body 202 from swinging.

[0035] It should be noted that the driving mechanism 10 in the embodiment of the present application can be used to drive the door body 202 in any direction, and the specific direction of force applied to the door body 202 can be achieved by setting the installation direction of the guide wheel 104 as needed; the connection between the driving member 101 and the adapter 102 can be a direct connection or an indirect connection using an intermediate member, which can satisfy the requirement of driving the adapter 102 to move in the required direction.

[0036] See also Figure 1Further, in the embodiment of the present application, the door body 202 is set to be lifted in the vertical direction as an example; the first transmission member 103 includes a first section 1031 and a second section 1032, one end of the first section 1031 is connected to the adapter 102, the other end of the first section 1031 is connected to one end of the second section 1032, and the other end of the second section 1032 is connected to the door body 202; the connection between the first section 1031 and the second section 1032 is matched with the guide wheel 104 for transmission, and the second section 1032 is set in the vertical direction.

[0037] In the embodiment of the present application, the first section 1031 and the second section 1032 of the first transmission member 103 are connected to form a whole chain structure. Taking the transmission matching point of the first transmission member 103 and the guide wheel 104 as the boundary, the section where the first transmission member 103 is connected to the adapter 102 is the first section 1031, and the section where the first transmission member 103 is connected to the door body 202 is the second section 1032. There may be an angle between the first section 1031 and the second section 1032, which can be used to make the force of the door body 202 There is an angle between the direction and the force direction of the driving member 101, so that the driving member 101 can be set at a position away from the door body or other side of the processing equipment 20. When the processing equipment 20 is a high-temperature equipment such as a heating furnace, such a setting can also prevent the driving member 101 from being affected by the high temperature near the furnace mouth and affecting the normal driving function, and the first transmission member 103 can be made of high-temperature resistant material. The first transmission member 103 of high-temperature resistant material can be used normally in a position close to the furnace mouth, for example, it can be a metal rope or a metal chain.

[0038] Specifically, the second section 1032 of the embodiment of the present application is set in the vertical direction as an example, so that the second section 1032 of the first transmission member 103 and the force of the door body 202 are in the same straight line in the vertical direction, which helps to improve the efficiency of the force; similarly, the first section 1031 is set in parallel to the moving direction of the adapter 102 as an example, which helps to improve the efficiency of the force of the adapter 102 on the first section 1031. It can be understood that the direction settings of the first section 1031 and the second section 1032 can respectively prevent the generation of invalid force components of the force, so as to avoid reducing the efficiency of the driving force of the driving member 101.

[0039] Furthermore, the driving mechanism 10 in any of the above embodiments may also include a second transmission member 105, the second transmission member 105 includes a first transmission wheel 1051, a second transmission wheel 1052 and a transmission chain 1053, the first transmission wheel 1051 is drivingly connected to the driving member 101, the second transmission wheel 1052 is rotatably arranged on the equipment, the transmission chain 1053 is transmission-connected to the first transmission wheel 1051 and the second transmission wheel 1052, and the adapter 102 is connected to the transmission chain 1053.

[0040] Taking the example of the driving member 101 and the adapter member 102 in the embodiment of the present application being connected by the second transmission member 105, the first transmission wheel 1051 and the second transmission wheel 1052 of the second transmission member 105 may be sprockets or guide wheels. When the first transmission wheel 1051 and the second transmission wheel 1052 are sprockets, the transmission chain 1053 is a chain meshed with the first transmission wheel 1051 and the second transmission wheel 1052; when the first transmission wheel 1051 and the second transmission wheel 1052 are guide wheels, the transmission chain 1053 is a belt-shaped transmission belt that is in close contact with the first transmission wheel 1051 and the second transmission wheel 1052 for transmission.

[0041] In the embodiment of the present application, the first transmission wheel 1051 and the second transmission wheel 1052 are specifically taken as sprockets, and the transmission chain 1053 is taken as a chain meshed with the first transmission wheel 1051 and the second transmission wheel 1052 as an example. The driving member 101 can drive the first transmission wheel 1051 to rotate. Compared with the first transmission wheel 1051 and the second transmission wheel 1052, the first transmission wheel 1051 can be understood as a driving wheel, and the second transmission wheel 1052 can be understood as a driven wheel that rotates through the transmission chain 1053. The first transmission wheel 1051 and the second transmission wheel 1052 are both rotatably arranged on the processing equipment 20 as an example. The transmission chain 1053 is closed head and tail and is sleeved on the outside of the first transmission wheel 1051 and the second transmission wheel 1052 as an example. After the adapter 102 is connected to the transmission chain 1053, as the transmission chain 1053 is driven by the driving member 101 and operates, the adapter 102 is driven by the transmission chain 1053 to move synchronously.

[0042] Of course, in the embodiment of the present application, the connection section of the transmission chain 1053 with the adapter 102 is arranged along the moving direction of the adapter 102, which helps to improve the efficiency of the driving force.

[0043] Furthermore, in the above-mentioned embodiment, the second transmission wheel 1052 and the guide wheel 104 are coaxially and relatively fixedly arranged. Specifically, the second transmission wheel 1052 and the guide wheel 104 are coaxially and fixedly arranged. In this way, when the driving member 101 drives the first transmission wheel 1051 to rotate, the guide wheel 104 can be driven to rotate through the transmission chain 1053. The embodiment of the present application is equivalent to using the adapter 102 in combination with the second transmission member 105 to drive the first transmission member 103 at the same time. This can not only ensure the operating stability of the first transmission member 103, but also help to improve the driving force of the first transmission member 103, thereby ensuring the stable movement of the door body 202.

[0044] Furthermore, the guide wheel 104 and the first transmission member 103 of the above-mentioned embodiment are correspondingly arranged in at least two groups. Taking two groups as an example, the guide wheel 104 is an example of a sprocket, and the first transmission member 103 is an example of a chain, that is, the embodiment of the present application adopts two sprockets and two chains, and each sprocket is meshed with a chain as a group.

[0045] Among them, the two sprockets serving as the guide wheels 104 are symmetrically arranged about the center of gravity of the door body 202, and the two chains serving as the first transmission members 103 are also symmetrically arranged about the center of gravity of the door body 202. It can be understood that the cooperation of the two sets of sprockets and chains is symmetrical about the center of gravity of the door body 202, so as to provide symmetrical forces on the door body 202, so that the force on the door body 202 is balanced.

[0046] Similarly, the sliding connection between the adapter 102 and the heating furnace 20 is symmetrical about the center of gravity of the door body 202, the connection between the adapter 102 and the first transmission member 103 is symmetrical about the center of gravity of the door body 202, and the connection between the adapter 102 and the transmission chain 1053 of the second transmission member 105 is symmetrical about the center of gravity of the door body 202.

[0047] In the embodiment of the present application, the two ends of the adapter 102 are slidably connected to the processing equipment 20, and the two ends of the adapter 102 slidably connected to the processing equipment 20 are symmetrical about the center of gravity of the door body 202; and the connection between the adapter 102 and the two chains as the first transmission member 103 is symmetrical about the center of gravity of the door body 202. Taking the connection between the adapter 102 and the transmission chain 1053 of the second transmission member 105 as an example, from the perspective of the effect of the force, when the connection between the transmission chain 1053 of the second transmission member 105 and the adapter 102 is driven by the transmission chain 1053 of the second transmission member 105, the two ends of the sliding connection processing equipment 20 of the adapter 102 are subjected to the same force, the connection between the adapter 102 and the two first transmission members 103 is also subjected to the same force, and the connection between the door body 202 and the two first transmission members 103 is also subjected to the same force.

[0049] In the embodiment of the present application, the driving mechanism 10 is arranged above the furnace mouth of the heating furnace 20. Specifically, the driving member 101, the adapter 102 and the guide wheel 104 of the driving mechanism 10 are arranged on the upper side of the furnace body 201, that is, on a different side from the furnace mouth, and the adapter 102 is connected to the door body 202 through a chain-shaped first transmission member 103, so that the driving member 101 can be protected from the high temperature of the furnace mouth. The heating furnace 20 of the embodiment of the present application, because it includes the driving mechanism 10 in any of the above embodiments, has the beneficial effects brought by the driving mechanism 10 in any of the above embodiments, which will not be repeated here.

[0052] The guide member 203 can be understood as guiding the door body 202 to be movable in the vertical direction, so as to help guide the door body 202 to move along the desired trajectory. The guide members 203 are relatively arranged at both ends of the furnace opening in the first direction, and at least one guide member 203 is adjustable along the first direction, so that the distance between the guide members 203 can be adjusted, so that the guide door body 202 can accurately correspond to the blocking and opening of the furnace opening. The specific adjustable setting method of the guide member 203 is not limited, and can be achieved by using a strip hole with a screw, or by other methods.

[0053] Further, the guide member 203 may include a first limiting portion 2031, which is opposite to the vertical edges on both sides of the furnace mouth and is adjustably arranged on the furnace body 201 along the first direction.
