[0046] Under the limiting action of the clamping limit seat 31, the rotational motion of the rotating mechanism is converted into the translational motion of the clamping locking member 32, which causes the first clamping plate 41 and the second clamping plate 42 to open and close.

[0047] Specifically, the driving device drives the impregnation drum 2 to rotate at a first predetermined angle, so that several sets of material clamping devices 4 sequentially flow to the opening clamping device 3 to perform opening clamping operations. This optimizes the independence of capacitor loading / unloading and impregnation operations, allowing one set of opening clamping device 3 to meet the requirements of the material clamping devices 4 for impregnation, spin-drying, and loading / unloading operations within the impregnation cylinder. Under the limiting action of the opening clamping limit seat 31, the rotational motion of the rotating mechanism is converted into the translational motion of the opening clamping locking member 32, causing any set of the first clamping plate 41 and the second clamping plate 42 to open and close. This enables automatic opening clamping operations to be completed within a limited space, reducing the need for redundant devices while ensuring the internal sealing of the equipment.

[0065] Furthermore, a sensing element is provided on the first driven wheel 333;

[0067] When the first photoelectric switch 335 senses the sensing sheet, it confirms that the first clamping plate 41 and the second clamping plate 42 have completed the clamping operation.

[0068] When the second photoelectric switch 336 senses the sensing sheet, it confirms that the first clamping plate 41 and the second clamping plate 42 have completed the clamping operation.

[0069] Specifically, when the first motor 331 operates, it drives the first driven wheel 333 to rotate a second predetermined angle so that the sensing element is sensed by the first photoelectric switch 335. At this time, the first clamping plate 41 and the second clamping plate 42 are in an open clamping state. When the first motor 331 continues to operate, it drives the first driven wheel 333 to continue rotating a second predetermined angle so that the sensing element is sensed by the second photoelectric switch 336. At this time, the first clamping plate 41 and the second clamping plate 42 are in a closed clamping state. The second predetermined angle can be set according to the actual use. In this embodiment, the second predetermined angle is 180°.

[0070] Furthermore, the impregnation drum 2 includes a second driven wheel;

[0071] The driving device includes a second motor and a second synchronous belt. The drive shaft of the second motor is fitted with a second driving wheel, which is connected to the second driven wheel via the second synchronous belt. Specifically, when the second motor operates, under the action of the second synchronous belt, it drives the impregnation roller 2 to rotate by a first predetermined angle each time, so that several sets of material clamping devices 4 sequentially flow to the opening clamping device 3 to perform opening clamping operations. The first predetermined angle can be set according to the actual usage. In this embodiment, there are 12 sets of material clamping devices 4, and the first predetermined angle is 30°.

[0072] When this utility model is in operation, it includes the following steps:

[0073] (1) When the first clamping plate 41 and the second clamping plate 42 are closed, the first motor 331 is working and drives the first driven wheel 333 to rotate 180°. The transmission column 334 moves in the conversion groove due to the rotation driven by the first motor 331, so that the clamping locking member 32 moves out under the limiting action of the clamping limiting seat 31, thereby driving the first clamping plate 41 and the second clamping plate 42 to be in the clamping state. At this time, the first photoelectric switch 335 senses the sensing sheet and confirms that the first clamping plate 41 and the second clamping plate 42 are in the clamping state to complete the clamping operation.

[0074] (2) Feed and / or feed a row of elements into the element clamping cavity;

[0075] (3) After the raw material is unloaded and / or loaded, the first motor 331 continues to work, driving the first driven wheel 333 to continue to rotate 180°, so that the clamping locking member 32 moves in under the limiting action of the clamping limit seat 31, thereby driving the first clamping plate 41 and the second clamping plate 42 to be in the clamping state. At this time, the second photoelectric switch 336 senses the sensing sheet and confirms that the first clamping plate 41 and the second clamping plate 42 are in the clamping state to complete the clamping operation.

[0076] (4) After the clamping device 4 is closed, the second motor works to drive the impregnation drum 2 to rotate 30°, that is, to drive the clamping device 4 to move away from the opening device 3 so that the seed can be impregnated. The next clamping device 4 that clamps the dried seed is brought close to the opening device 3, and the above steps are repeated.

[0077] This utility model is reasonably and ingeniously designed. The driving device drives the impregnation drum to rotate at a first predetermined angle, so that several sets of material clamping devices sequentially flow to the opening clamping device to perform opening and closing operations. This optimizes the independence of capacitor loading and unloading and impregnation operations. One set of opening clamping devices can meet the needs of the material clamping devices for impregnation, spin-drying and loading / unloading operations in the impregnation cylinder. Under the limiting action of the opening clamping limit seat, the rotational motion of the rotating mechanism is converted into the translational motion of the opening clamping locking member, which causes the control of any set of first clamping plates and second clamping plates to open and close. This realizes automatic opening and closing operations within a limited space, reduces the setting of redundant devices, and ensures the internal sealing of the equipment.

[0078] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model using the disclosed technical means and content, or modify it into equivalent embodiments with equivalent changes, without departing from the scope of the technical solution of this utility model.
