The preferred embodiment of the tin stripping device provided by the invention is shown in fig. 1 and 2, and comprises a tin stripping tank 1, a rotating shaft 2 connected between the front wall and the rear wall of the tin stripping tank, and more than 2 turntables 3 (2 are taken as an example in fig. 2) fixed on the rotating shaft; the bottom surface of the tin stripping groove is an arc surface 11 concentric with the rotating shaft, and is preferably a semicircular arc surface; the turntable is uniformly distributed on the rotating shaft with a first gap L1 and synchronously rotates along with the rotating shaft, and the end face of the turntable is provided with a plurality of limiting parts 31 (only 3 limiting parts are drawn in fig. 1); a push rod 4 is arranged on the left side of the tin stripping groove and used for pushing a product 7 into a limiting part of the turntable; and a pull rod 5 is arranged on the right side of the tin stripping groove and used for pulling out products from the limiting part of the turntable. The motion control of the push rod and the pull rod, the rotation of the rotary table driven by the rotary shaft and the product conveying of the conveyor belt 6 are all conventional technical means, and are not included in the inventive content of the invention, and are not described in detail herein. The working process of the equipment is as follows: when the push rod pushes in a product, the rotary table correspondingly rotates by an angle theta, wherein the angle theta is just equal to the included angle of the adjacent limiting parts, and then the pull rod correspondingly pulls out a product; alternatively, each time the turntable rotates by an angle θ, the push rod pushes in one product, and the pull rod pulls out one product. The setting may be selected according to the actual situation.
The tin stripping equipment provided by the invention occupies small area, a long production line is not needed, the whole tin stripping process is completed in the tin stripping tank, the soaking time of the product in the tin stripping tank can be adjusted by controlling the rotating speed of the rotating disc, and the operation is convenient.
