[0039] This application provides an embodiment of a deviation rectifying device for an oven. Specifically, please refer to Figure 1 and Figure 2 .

[0040] The deviation rectifying device for an oven in this embodiment includes: a deviation rectifying swing roller 06 arranged at the bypass of the electrode sheet 02 in the oven, a deviation rectifying sensor 03 for monitoring whether the electrode sheet 02 runs in the center, and a deviation rectifying actuator 09 arranged outside the oven. The deviation rectifying actuator 09 is connected to the deviation rectifying swing roller 06 through a limit transmission component for driving the deviation rectifying swing roller 06 to perform a deviation rectifying action. The deviation rectifying sensor 03 is electrically connected to the deviation rectifying actuator 09.

[0041] It should be noted that by placing the deviation rectifying swing roller 06 inside the high-temperature oven and the deviation rectifying actuator 09 in the normal-temperature environment outside the oven, it can effectively avoid damage to the deviation rectifying actuator 09 caused by the high-temperature environment, thereby solving the problem that the existing deviation rectifying device cannot work in the high-temperature environment inside the oven. When the deviation rectifying sensor 03 detects that the electrode sheet 02 is not running in the center, it will send a signal to the deviation rectifying actuator 09 to control the deviation rectifying actuator 09 to perform a deviation rectifying action to ensure that the electrode sheet 02 does not deviate during long-distance running inside the oven.

[0042] The above is the first embodiment of a deviation rectifying device for an oven provided by the present application. The following is the second embodiment of a deviation rectifying device for an oven provided by the present application. For details, please refer to Figures 1 to 5 .

[0043] The deviation rectifying device for an oven in this embodiment includes: a deviation rectifying swing roller 06 arranged at the bypass of the electrode sheet 02 in the oven, a deviation rectifying sensor 03 for monitoring whether the electrode sheet 02 runs in the center, and a deviation rectifying actuator 09 arranged outside the oven. The deviation rectifying actuator 09 is connected to the deviation rectifying swing roller 06 through a limit transmission assembly for driving the deviation rectifying swing roller 06 to perform a deviation rectifying action. The deviation rectifying sensor 03 is electrically connected to the deviation rectifying actuator 09.

[0044] The oven includes an oven body 16, a high-temperature heat-insulating sealing plate 01 arranged on the end face of the oven body 16, and a protective cover 04 arranged on the side of the high-temperature heat-insulating sealing plate 01 away from the oven body 16. The protective cover 04 is communicated with the inside of the oven body 16. Both the deviation rectifying sensor 03 and the deviation rectifying swing roller 06 are located inside the protective cover 04. Specifically, the high-temperature heat-insulating sealing plate 01 is detachably connected to the oven body 16; the deviation rectifying sensor 03 can be fixed on the high-temperature heat-insulating sealing plate 01.

[0045] A deviation rectifying support seat 08 is arranged directly below the protective cover 04. The deviation rectifying support seat 08 is fixedly connected to the high-temperature heat-insulating sealing plate 01. The limit transmission assembly includes an eight-shaped track 10 fixedly arranged on the deviation rectifying support seat 08 and two swing rods slidably arranged on the eight-shaped track 10. Two deviation rectifying operation avoidance holes 17 are correspondingly opened at the bottom of the protective cover 04. The tops of the two swing rods respectively extend into the protective cover 04 through the two deviation rectifying operation avoidance holes 17 and are respectively connected to both ends of the deviation rectifying swing roller 06. A floating seal 07 for preventing air leakage by following the movement of the swing rod is arranged at the deviation rectifying operation avoidance hole 17. The deviation rectifying actuator 09 is fixedly arranged on the deviation rectifying support seat 08, and the output end of the deviation rectifying actuator 09 is connected to one of the swing rods. By pushing the swing rod on the eight-shaped track 10 to move through the deviation rectifying actuator 09, the deviation rectifying swing roller 06 is driven to swing, and thus the corresponding deviation rectifying action is completed.

[0046] It can be understood that since the swing rod needs to move, the deviation rectifying operation avoidance holes 17 are correspondingly opened at the bottom of the protective cover 04 to prevent the swing rod from interfering with the protective cover 04 during the movement. At the same time, by using the floating seal 07 to seal the deviation rectifying operation avoidance holes 17, the high-temperature leakage can be effectively isolated to ensure the normal operation of the deviation rectifying actuator 09.

[0047] Specifically, the two deviation rectifying operation avoidance holes 17 are arranged in an eight-shaped manner, and the deviation rectifying operation avoidance holes 17 can be waist-shaped holes.

[0048] The floating seal 07 can be a flexible and telescopic structure, similar to a bellows structure. The swing rod passes through the floating seal 07, and the swing rod is sealingly connected to the floating seal 07, enabling the floating seal 07 to move along with the swing rod on the end face of the deviation rectification operation avoidance hole 17, thereby preventing air leakage from the deviation rectification operation avoidance hole 17. The material of the floating seal 07 is a high-temperature resistant material, and the high-temperature resistant material can be polytetrafluoroethylene.

[0049] An air dust removal device 05 for sucking out dust particles generated by the deviation rectification swing roller 06 during the deviation rectification action is arranged inside the protective cover 04. The dust removal port of the air dust removal device 05 is arranged facing the deviation rectification swing roller 06. It also includes a dust removal fan 15. The dust removal fan 15 is connected to the air dust removal device 05 through a hose, and uses the suction force of the fan to suck away and discharge the dust particles on the surface of the deviation rectification swing roller 06.

[0050] Specifically, the dust removal fan 15 is arranged outside the oven, and the air dust removal device 05 can be fixed on the tops of the swing rods at both ends of the deviation rectification swing roller 06.

[0051] An openable operation door 11 can be arranged on one side of the protective cover 04 away from the oven body 16 to facilitate later maintenance.

[0052] An upper air nozzle 12, a lower air nozzle 13, and a transmission roller 14 for driving the running of the pole piece 02 are arranged inside the oven body 16.

[0053] Specifically, the deviation rectification sensor 03 can be an optoelectronic sensor, and the deviation rectification actuator 09 can be an electric push rod.

[0054] During specific implementation, the pole piece 02 is dried by orbiting inside the oven. It normally runs in the middle of the transmission roller 14. However, the pole piece 02 may deviate during the running process in the oven. Therefore, at the orbiting part on the end face of the oven, this deviation rectification device is installed to prevent deviation. Specifically, the pole piece 02 is wound around the deviation rectification swing roller 06, and the transmission roller 14 supports and moves the pole piece 02 through the hot air baking of the upper air nozzle 12. When it reaches the deviation rectification swing roller 06 and turns to the lower air nozzle 13 for hot air baking, the self-blowing force of the lower air nozzle 13 makes the pole piece 02 float on the surface of the transmission roller 14 to complete the process of secondary baking inside the oven. During this period, the deviation rectification sensor 03 monitors in real time whether the pole piece 02 runs in the middle of the roller surface. Since the length of the transmission roller 14 is a little wider than that of the pole piece 02, the pole piece 02 will be torn off when the pole piece 02 deviates beyond the transmission roller 14. If the pole piece 02 does not run in the middle of the roller surface, the deviation rectification sensor 03 will collect signals and send them to the deviation rectification actuator 09, controlling the deviation rectification actuator 09 to contract or push the deviation rectification swing roller 06 on the eight-shaped track 10 to swing in the corresponding direction for straightening. During this process, since the deviation rectification actuator 09 is placed in the normal temperature environment outside the oven, and the deviation rectification operation avoidance hole 17 on the protective cover 04 is isolated from the high-temperature leakage through the floating seal 07, the normal operation of the deviation rectification actuator 09 can be effectively guaranteed.

[0055] In addition, in order to prevent the generation of broken materials at the turning point of the polar plate 02 on the deviation rectifying swing roller 06, a dust removal device 05 is arranged inside the turning of the polar plate 02 in this device, and a dust removal fan 15 is connected to the dust removal device 05 to suck away and discharge the dust particles on the surface of the deviation rectifying swing roller 06.

[0056] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present application.
