Before the drying apparatus of the present invention is described, a brief description will be given of a swing arm type opening and closing door structure of a vacuum drying oven of the prior art:

the rocker arm type door opening and closing structure comprises furnace doors which are in one-to-one correspondence with the openings of the furnace body, and rocker arm assemblies which drive the furnace doors to turn downwards to open the corresponding openings. The rocking arm subassembly generally need install in the left and right sides of furnace body, because rocking arm subassembly self has certain volume to the rocking arm subassembly often needs to maintain and need reserve operating space, consequently need occupy the great space of furnace body left and right sides. Further, when the lowest furnace door is turned downwards to open the corresponding opening, the furnace door needs to occupy the bottom space of the furnace body, so that the height of the furnace body is increased. In summary, in the prior art, the vacuum drying furnace adopts a rocker arm type door opening and closing structure, needs to occupy larger space at the bottom and the left and right sides of the furnace body, has lower space utilization rate, and is not suitable for being arranged in a narrow environment. Therefore, it is necessary to provide a structure that reduces the space required to be occupied, improves the space utilization, and enables the structure to be more suitable for being disposed in a narrow environment.

Referring to fig. 1, 2 and 3, a drying apparatus according to an embodiment of the present invention includes a furnace body 10 and a furnace door device 20. The furnace body 10 has at least two openings spaced in a first direction, and an object to be dried (e.g., a battery cell) can enter the furnace body 10 from the openings for drying. The door apparatus 20 includes a rail assembly 21 and at least two doors 22 corresponding to the at least two openings one by one, so that the corresponding openings can be closed or opened by the doors 22. The track assembly 21 is disposed on the furnace body 10 and is coupled to each furnace door 22.

The track assembly 21 is configured to drive movement of either oven door 22 in a first direction. An aligned position, in which each oven door 22 is aligned with the corresponding opening in the second direction during the movement of the oven door 22 in the first direction, and an open position, in which it partially coincides with the other oven door 22 in the second direction. Wherein the second direction is perpendicular to the first direction.

The track assembly 21 is further configured to drive movement of either oven door 22 in a second direction, an in-path alignment position during movement of each oven door 22 in the second direction, and a mating position for mating with the oven body 10 and closing the corresponding opening.

When one opening needs to be opened, the track assembly 21 drives the oven door 22 corresponding to the opening to be opened to move from the matching position to the aligning position along the second direction, and then moves from the aligning position to the opening position along the first direction under the driving of the track assembly 21, so that the opening to be opened is opened, and the dried object is conveniently fed or taken out; and, at this time, the oven door 22 is at least partially overlapped with another oven door 22 in a second direction perpendicular to the first direction. Therefore, on one hand, the oven door 22 is translated along the first direction from the alignment position to the opening position, and on the other hand, when the oven door 22 is at the opening position, the oven door 22 is partially overlapped with the other oven door 22 in the second direction, so that the oven door 22 does not need to occupy larger space in the whole process from opening closing to opening, the space utilization rate is improved, and the oven door is more suitable for being arranged in a narrow environment.

It should be noted that, when the opening needs to be opened, the corresponding oven door 22 is first driven to move from the mating position to the aligned position along the second direction, that is, the aligned position is located at the side of the mating position facing away from the oven body 10, so that on one hand, the oven door 22 is separated from the oven body 10, and on the other hand, the oven door 22 can overlap with other oven doors 22 in the second direction during the movement of the oven door 22 along the first direction without interfering with other oven doors 22.

Further, the rail assembly 21 is disposed on one side of the furnace body 10 having the opening, i.e., on the front side of the furnace body 10, so that the space occupied on the left and right sides of the furnace body 10 is not required, and the space utilization rate is further improved.

The drying device may be a vacuum drying device, and may be other types of drying devices, which is not limited herein.

It will be appreciated that, because each oven door 22 corresponds to a different opening, each oven door 22 has a corresponding open position, aligned position, and mated position during movement in the first and second directions. That is, the opening position, the alignment position, and the coupling position of each oven door 22 are different from each other, and the opening position and the alignment position of each oven door 22 are located on a straight line parallel to the first direction.

In some embodiments, the rail assembly 21 includes a mounting seat 211 and at least two moving seats 212, the mounting seat 211 is mounted on the furnace body 10, and the mounting seat 211 is provided with a fixing rail 2112 extending lengthwise along a first direction. Each movable base 212 is provided with a first rail 2123 extending lengthwise in a first direction.

Each oven door 22 is movably connected to the first rail 2123 of the corresponding moving seat 212, and when the moving seat 212 moves the corresponding oven door 22 along the second direction to the aligned position, the first rail 2123 is abutted to the fixed rail 2112, so that the oven door 22 can move along the first rail 2123 to the fixed rail 2112 and move along the fixed rail 2112 to the open position. In this manner, the oven door 22 is capable of moving in the second direction with the moving seat 212 (i.e., moving between the mated position and the aligned position), and when the moving seat 212 moves the oven door 22 to the aligned position, the first rail 2123 of the moving seat 212 is in abutment with the fixed rail 2112, such that the oven door 22 can move along the first rail 2123 onto the fixed rail 2112 and along the fixed rail 2112 (i.e., moving between the aligned position and the open position), thereby enabling the oven door 22 to open or close the corresponding opening.

In one embodiment, each movable base 212 further has a second rail 2124, and the second rail 2124 is parallel to the first rail 2123 and spaced from the first rail 2123 along the second direction. When the moving seat 212 moves the corresponding oven door 22 to the matching position, the second rail 2124 of the moving seat 212 is abutted with the fixed rail 2112, so that other oven doors can pass through the opening.

The process of opening and closing the opening of the door 22 will be described below taking as an example the case where the furnace body 10 has two openings: for convenience of description, the two openings are named a first opening and a second opening, respectively, the oven door 22 corresponding to the first opening is named a first oven door, and the oven door 22 corresponding to the second opening is named a second oven door; the matching position, the aligning position and the opening position corresponding to the first furnace door are named as a first matching position, a first aligning position and a first opening position respectively; the matching position, the aligning position and the opening position corresponding to the second oven door are named as a second matching position, a second aligning position and a second opening position respectively.

Initially, the first door is in the first mating position such that the first door mates with the oven body 10, thereby closing the first opening. At this time, the first oven door is movably connected with the first rail 2123 of the corresponding moving seat 212, and the second rail 2124 of the moving seat 212 corresponding to the first oven door is butted with the fixed rail 2112. The second door is also in the second mated position such that the second door is mated with the oven body 10, thereby closing the second opening. At this time, the second oven door is movably connected with the corresponding first rail 2123 of the moving seat 212, and the second rail 2124 of the moving seat 212 corresponding to the second oven door is butted with the fixed rail 2112.

When the first opening needs to be opened, first, the first oven door is moved to the first alignment position along the second direction under the driving of the moving seat 212 corresponding to the first oven door, so that the first rail 2123 on the moving seat 212 corresponding to the first oven door is in butt joint with the fixed rail 2112. The first oven door then moves along the first rail 2123 onto the fixed rail 2112 and along the fixed rail 2112 towards the second oven door until the first open position is reached. At this time, the first oven door and the second oven door partially or completely coincide in the second direction. It should be noted that, since the second rail 2124 of the moving seat 212 corresponding to the second oven door is abutted with the fixed rail 2112, the second rail 2124 is accessible during the process of moving the first oven door to the first open position along the fixed rail 2112, so that the first oven door can be smoothly moved to the first open position.

When it is desired to close the first opening, the first oven door is returned to the first alignment position along the fixed track 2112 such that the first oven door is movably coupled to its corresponding first track 2123 on the moving seat 212. Then, the moving seat 212 corresponding to the first door is moved to the first mating position along the second direction, so that the first door is mated with the oven body 10 to close the first opening.

When the second opening needs to be opened, first, the second oven door is moved to the second alignment position along the second direction under the driving of the moving seat 212 corresponding to the second oven door, so that the first rail 2123 on the moving seat 212 corresponding to the second oven door is butted with the fixed rail 2112. Then, the second door moves along the first rail 2123 onto the fixed rail 2112 and along the fixed rail 2112 toward the first door until reaching the second open position. At this time, the second oven door and the first oven door partially or completely coincide in the second direction. It should be noted that, since the second rail 2124 of the moving seat 212 corresponding to the first oven door is abutted against the fixed rail 2112, the second rail 2124 is accessible during the process of moving the second oven door to the second open position along the fixed rail 2112, so that the second oven door can be smoothly moved to the second open position.

When it is desired to close the second opening, the second oven door is returned to the second alignment position along the fixed rails 2112 such that the second oven door is movably connected with its corresponding first rail 2123 on the moving seat 212. Then, the moving seat 212 corresponding to the second door is moved to a second mating position along a second direction, so that the second door is mated with the oven body 10 to close the second opening.

In an embodiment of the present invention, the track assembly 21 further includes a first driving mechanism 213, and the first driving mechanism 213 is disposed on the mounting seat 211 and can be in transmission connection with the oven door 22 located at the aligned position and the open position to drive the oven door 22 to move between the aligned position and the open position.

Specifically, in the embodiment, the first driving mechanism 213 includes a driving plate 2131 and a first driving structure, the driving plate 2131 is movably connected to the mounting base 211 along a first direction, and the first driving structure is disposed on the mounting base 211 and is in transmission connection with the driving plate 2131 to drive the mounting plate 231 to move along the first direction.

The driving plate 2131 has a connecting portion a, and each of the oven doors 22 has a fitting portion. When the oven door 22 moves to the aligned position along the second direction, the connecting portion a of the driving plate 2131 can be inserted into and matched with the matching portion of the oven door 22, so that the oven door 22 can move along the first direction along with the driving plate 2131. Alternatively, the matching portion may be a plug hole, and the connecting portion a may be plugged into the plug hole, so that the driving plate 2131 may drive the oven door 22 to move along the first direction.

In an embodiment, the driving plate 2131 is provided with a first slider, the mounting seat 211 is provided with a first sliding rail 2112 extending lengthwise along a first direction, and the first slider is slidably engaged with the first sliding rail 2112, so that the driving plate 2131 can move along the first direction.

Specifically, in the embodiment, the first driving structure further includes a driving wheel 2132, a driven wheel 2133, a transmission belt 2134 and a first driving element 2135. The driving wheel 2132 and the driven wheel 2133 are arranged on the mounting seat 211 at intervals along a first direction, and the transmission belt 2134 is sleeved between the driving wheel 2132 and the driven wheel 2133 so as to move forward sequentially along the first direction under the driving of the driving wheel 2132. The transmission belt 2134 is connected with the driving plate 2131 to drive the driving plate 2131 to move along a first direction. The first driving element 2135 is disposed on the mounting base 211 and is in transmission connection with the driving wheel 2132 to drive the driving wheel 2132 to rotate. Thus, the first driving member 2135 drives the driving wheel 2132 to rotate, so as to drive the transmission belt 2134 to move between the driving wheel 2132 and the driven wheel 2133 along the first direction, and further drive the driving plate 2131 to move along the first direction. Alternatively, the first drive 2135 can be a motor. The output shaft of the first driving element 2135 and the wheel shaft of the driving wheel 2132 can be connected through a synchronous belt transmission, so that the first driving element 2135 can drive the driving wheel 2132 to rotate.

In an embodiment of the present invention, the track assembly 21 further includes at least two second driving mechanisms 214 corresponding to the at least two moving bases 212. Each second driving mechanism 214 is disposed on the mounting base 211 and is in transmission connection with the corresponding movable base 212 to drive the movable base 212 to move along the second direction.

In one embodiment, the second driving mechanism 214 includes a second driving member 2141, and the second driving member 2141 has a mounting end and a telescopic end that is telescopic relative to the mounting end. The mounting end is connected to the mounting seat 211, and the telescopic end is connected to the movable seat 212, so that the telescopic end drives the movable seat 212 to move along the second direction when stretching relative to the mounting end. Alternatively, the second drive 2141 may be a cylinder.

In an embodiment, the movable seat 212 is provided with a second slider 2121, the mounting seat 211 is provided with a second sliding rail 2111 extending lengthwise along the second direction, and the second slider 2121 is slidably engaged with the second sliding rail 2111, so that the movable seat 212 moves more stably and reliably along the second direction.

Referring to fig. 1 to 4, in an embodiment of the present invention, the oven door apparatus 20 further includes a traveling mechanism 23 mounted to the oven door 22, and the traveling mechanism 23 is movably connected to the first rail 2123 and the fixed rail 2112, so that the oven door 22 can move along the first rail 2123 and the fixed rail 2112.

In one embodiment, the fixed rail 2112 and the first rail 2123 have two opposing first rail surfaces in the second direction, each extending lengthwise in the first direction. The traveling mechanism 23 includes a mounting plate 231 and a first traveling wheel set 232 mounted on the mounting plate 231, and the first traveling wheel set 232 includes two first traveling wheels 2321 spaced apart in the second direction.

When the traveling mechanism 23 is movably connected to the fixed rail 2112, the two first traveling wheels 2321 are respectively in rolling engagement with the two first rail surfaces of the fixed rail 2112, so that the traveling mechanism 23 is limited in the second direction, and the traveling mechanism 23 can move along the fixed rail 2112. When the traveling mechanism 23 is movably connected to the first rail 2123, the two first traveling wheels 2321 are respectively in rolling engagement with the two first rail surfaces of the first rail 2123, so as to limit the traveling mechanism 23 in the second direction, and the traveling mechanism 23 moves along the first rail 2123.

Further, the first traveling wheel set 232 may include a plurality of sets (i.e., two or more sets), and the plurality of sets of the first traveling wheel set 232 are spaced apart along the first direction.

Furthermore, the mounting plate 231 is provided with avoiding grooves b extending lengthwise along the first direction, and the two first running wheels 2321 of each first running wheel group 232 are respectively located at two opposite sides of the avoiding grooves b, so that when the running mechanism 23 is movably connected with the rail (i.e., the fixed rail 2112, the first rail 2123 or the second rail 2124), the avoiding grooves b can perform an avoiding function on the rail, and interference generated when the running mechanism 23 moves along the rail is avoided.

In particular embodiments, the fixed rail 2112 has a second rail surface perpendicular to the first rail surface, and the second rail surface extends lengthwise in the first direction. The traveling mechanism 23 further includes a plurality of second traveling wheels 233 mounted on the mounting plate 231.

When the traveling mechanism 23 is movably connected to the fixed rail 2112, the second traveling wheels 233 are in rolling engagement with the second rail surfaces of the fixed rail 2112, thereby supporting the oven door 22 and the traveling mechanism 23 in the third direction such that the traveling mechanism 23 can move along the fixed rail 2112.

Further, the fixing rail 2112 includes a transverse plate fixedly connected to the mounting seat 211 and a first longitudinal plate vertically disposed on a side of the transverse plate away from the mounting seat 211, and both the transverse plate and the first longitudinal plate extend lengthwise along the first direction. The surfaces of the first vertical plate on opposite sides in the second direction are two first rail surfaces of the fixed rail 2112, and the surface of the lateral plate on the side facing the vertical plate is a second rail surface of the fixed rail 2112.

In an embodiment, when the traveling mechanism 23 is movably connected to the first rail 2123, the second traveling wheels 233 are in rolling engagement with the moving seat 212 to support the oven door 22 and the traveling mechanism 23 in the third direction such that the traveling mechanism 23 can move along the first rail 2123.

Further, the plurality of second traveling wheels 233 are respectively located at opposite sides of the escape groove b, so that the oven door 22 moves along the rail along with the traveling mechanism 23 more stably and reliably.

In particular embodiments, the traveling mechanism 23 may also be movably coupled to the second rail 2124 such that the traveling mechanism 23 may pass through the second rail 2124 as it moves along the fixed rail 2112. Note that the second track 2124 and the first track 2123 use the same track.

Further, the first rail 2123 and the second rail 2124 each include a second longitudinal plate standing on the movable base 212, and the second longitudinal plate extends lengthwise along the first direction. The surfaces of the second longitudinal plate on the opposite sides in the second direction are two first track surfaces of the first track 2123 or the second track 2124.

In the embodiment, the moving base 212 at the end of the furnace body 10 in the first direction is provided with a baffle plate, which can prevent the traveling mechanism 23 from sliding out of the furnace body 10 along the first rail 2123 and derailing. Further, a stopper is disposed on the mounting seat 211, and the stopper is used for cooperating with the stopper to prevent the traveling mechanism 23 from moving back and forth along the first rail 2123 in a process that the traveling mechanism 23 drives the corresponding furnace door 22 to move away from the alignment position along the second direction and to the matching position, which is beneficial to improving the matching degree between the furnace door 22 and the furnace body 10 and improving the effect of sealing the opening. Of course, when the traveling mechanism 23 moves the corresponding oven door 22 to the aligned position, the stopper cannot prevent the traveling mechanism 23 from moving from the first rail 2123 to the fixed rail 2112.

In the embodiment of the present invention, the furnace body 10 has a plurality of openings, and the plurality of openings are arranged in layers along the third direction. Each layer of openings comprises at least two openings which are arranged at intervals along the first direction. Each layer of openings is correspondingly provided with an oven door device 20 for closing or opening each opening in the corresponding layer.
