8. The automatic processing equipment for the accessories of the food refrigeration equipment as claimed in claim 1, wherein the second forming frame is provided with a material taking mechanism, the material taking mechanism comprises a material taking block, the material taking block is provided with a semicircular groove which is in clearance fit with the supporting roller, the inner diameter of the semicircular groove is smaller than that of the forming groove of the forming block, the length of the material taking block in the front-back direction is smaller than the distance between the steel belt and the rotating seat, the material taking block is connected with a fourth linear driving mechanism which is used for driving the material taking block to move along the axial direction of the supporting roller, and the fourth linear driving mechanism is connected with a fifth linear driving mechanism which is used for driving the material taking block to move along the radial direction of the rotating seat;
and the two ends of the supporting roller are connected with the rotating seat through supporting rods, the width of each supporting rod is smaller than the diameter of the supporting roller, and the distance between the outer end of each supporting rod and the center of the supporting roller is smaller than the radius of the supporting roller.
9. The automatic processing equipment for food refrigeration equipment accessories according to claim 8, wherein the fourth linear driving mechanism comprises a second sprocket seat connected with the fifth linear driving mechanism, two second sprockets symmetrically arranged in front and back are arranged on the second sprocket seat, a second chain is wound on the two second sprockets, and one or more chain links on one side of the second chain, which is close to the rotating seat, are connected with the material taking block.
10. The automatic processing equipment for food refrigeration equipment accessories as claimed in claim 1, wherein an electromagnet is arranged on the second forming rack on the right side of the forming block on the right side of the three forming blocks.
