[0019] As Figures 1-4 The utility model discloses a feeding device for thread rolling machine, including mobile support 1, the lower end of mobile support is installed with walking wheel 2;

[0020] The mobile support is fixedly installed with cylinder 3, and both ends of the cylinder are fixed with cylinder cover 4, and the cylinder is rotationally matched with feeding roller 5, and both ends of the feeding roller are fixed with rotating shaft, and the rotating shaft is connected with the cylinder cover through bearing, one of the cylinder covers is fixedly installed with servo motor 6, the output shaft of servo motor is fixedly connected with the outer end of rotating shaft, the circumference of feeding roller is provided with a plurality of feeding grooves 7, the feeding groove and the inner side wall of the cylinder form a containing area for containing a single product to be rolled, the cylinder is installed with feeding arrangement assembly, the lower end of the cylinder cover is opposite to the opening, one end of the mobile support is installed with pushing assembly, and the end of the cylinder away from the pushing assembly is provided with supporting assembly.

[0021] In this way, the product to be rolled is in a rod shape, the product to be rolled is arranged in the feeding arrangement assembly, the product to be rolled in the feeding arrangement assembly reaches the feeding groove of the feeding roller, the feeding roller is driven to rotate by the servo motor, and then the product to be rolled is driven to the lowermost end and opposite to the opening, the pushing assembly pushes the product to be rolled out to the supporting assembly, the supporting assembly is arranged on one side of the thread rolling machine, when the pushing assembly pushes the product to be rolled, one end of the product to be rolled enters the thread rolling position of the thread rolling machine to perform thread rolling operation, after the thread rolling is completed, the supporting assembly is released, and the product after thread rolling falls down. Repeat the above process until all the products to be rolled are completed.

[0022] Specifically, the containing area for containing a single product to be rolled is formed between the feeding groove and the inner side wall of the cylinder, the maximum size of the feeding groove is greater than the diameter of the product to be rolled and less than 2 times the diameter of the product to be rolled, so that the feeding roller can take away the single product to be rolled falling from the feeding arrangement assembly. When not in use or when other workpieces need to be rolled, the whole structure can be pushed to the corner of the workshop, and other corresponding feeding devices can be replaced. Through the setting of the feeding roller, single automatic feeding to the thread rolling position of the thread rolling machine is realized, and the reliability is improved.

[0023] In implementation, the feeding arrangement assembly comprises a hopper 8 with an open upper end, a feeding opening 9 is fixed to the lower end of the hopper, the feeding opening is matched with a single product to be rolled, and the lower end of the hopper has two inwardly inclined guide plates 10 in the direction close to the feeding opening. The hopper is of a conventional structure, the width of the feeding opening is greater than the diameter of the single product to be rolled and less than twice the diameter of the product to be rolled, so as to facilitate the arrangement and sequential falling of the product to be rolled in the vertical direction.
