Description

Technical Field

[0001] The utility model relates to the technical field of ovens, in particular to an active roller transmission device for an oven. Background Art

[0002] Currently, most lithium battery extrusion positive and negative electrode coating equipment on the market have active steel rollers in the oven as the traction power for the foil.

[0003] In the prior art, oven drive rollers generally have two transmission methods: a motor driven through a synchronous pulley and a coupling. First, with the motor driven through the synchronous pulley, due to the oven's machining precision limitations, the synchronous belt and the synchronous pulley on the active steel roller are not fully engaged. This, coupled with the oven's heat transfer to the synchronous belt, results in severe belt wear, frequent belt breakage, and high noise levels during transmission. Second, with the motor driven through a coupling, due to the oven's machining precision limitations, the motor and active steel roller are misaligned, which can easily lead to roller shaft breakage. These two situations severely impact equipment stability and customer productivity, increasing production costs and making it impossible to meet customer application requirements.

[0004] Therefore, it is necessary to design a driving roller transmission device for an oven to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of the utility model is to provide an oven active roller transmission device, so as to improve the mechanical contact engagement of the active roller transmission into magnetic engagement, thereby improving the absence of physical contact during the power transmission process. Through the active roller transmission device, the mechanical equipment of the oven used for lithium battery production and manufacturing basically does not require maintenance or shutdown for replacement. Especially in the production line of lithium battery production with extremely high cleanliness requirements, it does not have friction loss, so it does not require lubrication. It has the advantages of strong targeting, stability and reliability, and excellent finished product quality, realizing fast and economical production and manufacturing, thereby solving the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] An oven active roller transmission device comprises an oven body and an active steel roller, wherein a processing chamber is provided inside the oven body, an upper drying hood is installed at the top of the inner wall of the processing chamber, an upper guide seat is installed at the lower edge of the upper drying hood, a lower drying hood is installed at the bottom end of the oven body, a lower guide seat is installed at the upper edge of the lower drying hood, foil is transported between the lower guide seat and the upper guide seat, a box door is embedded in the outer surface of the oven body near the processing chamber, a machine cover is installed on the outer side of the oven body near the front side of the box door, a motor is installed on the inner wall of the machine cover away from the oven body, a bearing frame is installed in the machine cover near the oven body, a rotating shaft is rotatably installed between the output end of the motor and the adjacent side of the bearing frame, an active magnetic wheel is sleeved on the rotating shaft, an active steel roller is provided inside the processing chamber, one end of the active steel roller passes through a sealed bearing and extends into the machine cover, and a passive magnetic wheel is sleeved on the upper edge of the active magnetic wheel, and the other end of the active steel roller is rotatably connected to the right side of the inner wall of the processing chamber through a bearing seat.

[0008] As a preferred solution of the present invention, there are four doors in total, which are connected and installed via door hinges, and are provided with door handles and observation windows.

[0009] As a preferred solution of the present invention, there are four hoods in total, and a plurality of heat dissipation holes are opened on the outer surface of the hood.

[0010] As a preferred solution of the present invention, a plurality of upper guide seats and lower guide seats are arranged in a staggered manner.

[0011] As a preferred solution of the present invention, there are four of each of the motor, the active magnetic wheel, the active steel roller and the passive magnetic wheel.

[0012] As a preferred solution of the present invention, the active magnetic wheel and the passive magnetic wheel are in a parallel non-contact magnetic transmission structure, and both the active magnetic wheel and the passive magnetic wheel are composed of neodymium iron boron permanent magnets.

[0013] Beneficial effect: In view of the problem that the existing technology cannot improve the non-contact magnetic transmission of the active roller of the oven, in the utility model, through the active magnetic wheel and the passive magnetic wheel, when the motor drives the active magnetic wheel to start rotating, due to the effect of the magnetic field, the passive magnetic wheel will be pulled to rotate synchronously through the magnetic lines of force. The rotation of the passive magnetic wheel drives the active steel roller to rotate, and the rotation of the active steel roller drives the foil to move forward, thereby realizing contactless power transmission. This transmission method does not rely on direct mechanical connection, but relies entirely on the magnetic field to realize torque transmission, and converts mechanical contact engagement into magnetic engagement. There is no physical contact in the power transmission process. Through the active roller transmission device, the mechanical equipment of the oven used for lithium battery production and manufacturing basically does not require maintenance, and there is no need to shut down for replacement. Especially in the production line of lithium battery production with extremely high cleanliness requirements, it does not have friction loss, so no lubrication is required.
