[0020] In the present invention, unless otherwise specified and limited, the terms "assembly", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can also be a mechanical connection; it can be directly connected, or it can be connected through an intermediate medium, or the two elements can be internally connected. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] The following is a further description of the specific implementation of the utility model in conjunction with the drawings of the specification, so that the technical solution and its beneficial effects of the utility model are clearer and more explicit. The following description of the embodiments with reference to the drawings is exemplary and intended to explain the utility model, but cannot be understood as limiting the utility model.

[0022] The preferred embodiment provided by the utility model is as follows: Figure 1 to Figure 4 As shown, a feeding device of a straightening machine includes a feeding frame group 1, a lifting cylinder 2, a translation cylinder 3, a supporting station 4, and a blocking part 5. The lifting cylinder 2 and the translation cylinder 3 can adopt existing air cylinders, air rods, hydraulic rods or hydraulic cylinders.

[0023] The feed frame group 1 includes a support frame 11, an adjustment motor 12, a first guide bar 13 and a second guide bar 14, wherein the first guide bar 13 and the second guide bar 14 are installed on the support frame 11, and the first guide bar 13 and the second guide bar 14 are separated so that a feed roller 15 is formed between the first guide bar 13 and the second guide bar 14; the adjustment motor 12 is connected to drive the first guide bar 13 and the second guide bar 14 to move so as to adjust the size of the feed roller 15;

[0024] The blocking part 5 is arranged at the end of the feed rack group 1, and the blocking part 5 is connected to the lifting cylinder 2 so that the blocking part 5 can move at the end of the feed rack group 1. The blocking part 5 is controlled by the lifting cylinder 2 to adapt to the height of the feed rack group 1; a protrusion 51 extends from one end of the blocking part 5 away from the guide plate 19.

[0025] The supporting station 4 is connected to the lifting cylinder 2 and the translation cylinder 3. The supporting station 4 is moved to the feeding rack group 1 by the translation cylinder 3. The supporting station 4 is moved up and down relative to the blocking part 5 by the lifting cylinder 2. The supporting station 4 is provided with a first supporting joint 41 and a second supporting joint 42, which are respectively arranged at two ends of the supporting station 4; the first supporting joint 41 and the second supporting joint 42 both have a concave position 43 for supporting the shaft rod, and the concave position 43 is V-shaped.

[0026] The support frame 11 has a guide plate 19, and the guide plate 19 is inclined relative to the supporting station 4. The first guide bar 13 and the second guide bar 14 have the same structural features. The first guide bar 13 includes a slat 16 and a guide block 17. The slat 16 and the guide block 17 are respectively arranged at the upper and lower ends of the guide plate 19, and the slat 16 and the guide block 17 are locked together by screws. The adjusting motor 12 is installed on the guide plate 19, and the guide plate 19 is provided with a guide groove 18. The guide groove 18 is in the shape of a long strip for the guide bar to move. The screw is inserted into the guide groove 18 to connect the slat 16 and the guide block 17 together. The rotating end of the adjusting motor 12 is connected with a screw 6. The first guide bar 13 and the second guide bar 14 are connected to the screw 6 through the guide blocks 17 of the two. The adjusting motor 12 drives the screw 6 to bring the first guide bar 13 and the second guide bar 14 closer or separate to adjust the size of the feeding roller 15.

[0027] The screw 6 connected to the adjusting motor 12 has a first thread segment 61 and a second thread segment 62, which are respectively arranged at both ends of the screw 6, and the directions of the first thread segment 61 and the second thread segment 62 are opposite, and the guide block 17 is correspondingly provided with a screw hole for the screw 6 to be connected; the first guide bar 13 and the second guide bar 14 are respectively connected to the first thread segment 61 and the second thread segment 62, when the adjusting motor 12 rotates, the first guide bar 13 and the second guide bar 14 can be controlled to move toward or away from each other, thereby adjusting the size of the feeding roller 15 to adapt to various shafts.

[0028] After the size of the feeding roller 15 is determined, the shaft rod is placed on the feeding roller 15. Since the guide plate 19 is inclined relative to the supporting station 4, the shaft rod will roll toward the supporting station 4 under the action of gravity; when the shaft rod moves to the blocking portion 5, the protrusion 51 will block the shaft rod from continuing to move to limit the position of the shaft rod; the blocking portion 5 is provided with an empty space 52, and the lifting cylinder 2 and the translation cylinder 3 of the supporting station 4 cooperate to move so that the first supporting joint 41 or the second supporting joint 42 of the supporting station 4 enters the empty space 52, and the shaft rod of the blocking portion 5 is taken out and moved to the straightening mechanism of the straightening machine for the next step of inspection and processing.
