[0002] The refrigerator backplate is a plate installed on the back of the refrigerator, which is generally made of metal material, plastic material or glass material. The metal material is usually galvanized steel plate, which has good appearance quality, is beneficial to heat exchange, fast heat dissipation, can prolong the preservation time and is not easy to breed bacteria. The plastic material is usually hard plastic, which has the characteristics of low cost, light weight, flexibility and insulation. The glass material has good gloss and light reflection effect, is not easy to drop paint, is more wear-resistant and easy to clean. Therefore, the backplate can have protection, heat insulation and heat dissipation effects. However, the refrigerator backplate made of metal material and plastic material has many burrs on the upper end during production and processing, so it needs to be processed by a cambered surface finishing mechanism.

[0003] The refrigerator backplate upper end cambered surface finishing device generally consists of a workbench, clamps, a transmission mechanism and a grinder. When using, the refrigerator backplate to be processed is placed on the workbench, the clamps on both sides are driven by the transmission mechanism to clamp and limit the backplate, and then the burrs on the upper end of the backplate are polished and removed by the grinder.

[0004] The transmission mechanism of the traditional refrigerator backplate cambered surface finishing device generally only uses a simple electric telescopic rod to drive the clamp to move, so as to clamp and limit the backplate by the clamp. Although this clamping method is relatively convenient to use, the end of the refrigerator backplate has a certain curvature. Therefore, when the clamp clamps the backplate, it usually only clamps the sides of both ends, and the clamping and limiting area is small. Therefore, during polishing, the backplate is easy to shake due to the polishing and extrusion of the grinder, which affects the subsequent polishing effect. UTILITY MODEL CONTENTS

[0010] As the preferred technical scheme, the upper side of the threaded plate is fixedly connected with a placing plate, and the upper side of the one end of the placing plate is fixedly connected with a supporting plate.

[0011] As the preferred technical scheme, the upper end of the supporting plate is fixedly connected with an electric telescopic rod, and the one end of the electric telescopic rod away from the supporting plate is rotationally connected with a pressing plate.

[0012] Through the above technical scheme, the rotation connection of the electric telescopic rod and the pressing plate facilitates the pressing plate to be pushed at one end to drive the rubber sleeve at the other end to clamp and limit the backplate.

[0013] As the preferred technical scheme, the two ends of the pressing plate are fixedly connected with a fixed block, and the inner side of the fixed block is rotationally connected with a roller, and the outer side of the roller is fixedly connected with a rubber sleeve.
