The detection mechanism 3 and the detection accommodating unit 2 are respectively arranged on both sides of the step feeding unit 1, so as to realize the rapid connection of the two processes of round rod 4 feeding and detection, reduce the equipment footprint, and improve production efficiency.

[0079] In this embodiment, the step feeding unit 1 comprises:

[0080] The material box 11 has a bottom plate 111 tilted forward at the bottom; both sides of the front of the material box 11 are respectively provided with a discharge port 113 connected to the detection cavity 211 and a through hole 114 through which the detection end of the detection mechanism 3 passes;

[0083] The stepped displacement cylinder 14 has a telescopic end connected to all the slide plates 13 ; the axial direction of the stepped displacement cylinder 14 is perpendicular to the plate surface of the inclined plate 12 .

[0084] Through the operation of the step displacement cylinder 14, the slide plate 13 is driven to slide between the inclined plates 12, so that the round rods 4 can be smoothly lifted in steps, and the inclined bottom plate 111 can ensure that all the round rods 4 are loaded.

[0085] In this embodiment, the step feeding unit 1 further includes:

[0086] A guide rod 15 is provided on the material box 11;

[0087] The guide block 16 is mounted on the material box 11 and is fixedly connected to the slide plate 13 to guide the slide plate 13 to slide between two adjacent inclined plates 12;

[0089] The detection sensor 18 is disposed on the partition 17 and faces the bottom plate 111 . A through hole is provided on the bottom plate 111 at a position facing the detection sensor 18 .

[0090] The guide rod 15 and the guide block 16 can improve the stability of the movement of the stepped displacement cylinder 14 , and the partition 17 can prevent a large number of round bars 4 from directly accumulating and squeezing onto the inclined plate 12 and the slide plate 13 , thereby reducing the risk of the stepped displacement cylinder 14 getting stuck.

[0091] The detection sensor 18 can detect whether there are round rods 4 inside the material box 11. The detection sensor 18 can be of a distance detection type. When the perforation detection distance increases to a predetermined upper limit, it can be known that there are no round rods 4 in the material box 11.

[0092] In this embodiment, the step feeding unit 1 further includes:

[0093] The guide cylinder 19 is arranged vertically downward just above the front plate 112 of the material box 11;

[0094] The guide block 101 is arranged on the telescopic end of the guide cylinder 19 to close the receiving groove formed by the front plate 112 of the material box 11 and the topmost slide plate 13;

[0095] At least two in-position sensors 102 are disposed on the front plate 112 of the material box 11 , facing the receiving groove formed by the front plate 112 of the material box 11 and the topmost slide plate 13 .

[0096] The in-position sensor 102 can detect whether the round rod 4 is loaded in place. The function of the guide cylinder 19 and the guide block 16 is to ensure that the round rod 4 can be smoothly pushed into the detection chamber 211 by the push rod 32.

[0097] In this embodiment, the detection accommodating unit 2 further includes:

[0098] The accommodating plate 21 has a concave groove-shaped detection cavity 211 on its lower surface; the accommodating plate 21 is provided with a top pressure hole 212 facing the detection cavity 211, and the top pressure part of the top pressure assembly contacts the round rod 4 located in the detection cavity 211 through the top pressure control;

[0099] The support plate 24 is disposed directly below the accommodating plate 21, and the upper plate surface of the support plate 24 and the detection cavity 211 form a hole-shaped structure with an opening pointing to the discharge port 113;

[0100] The waste box 25 is located directly below the detection chamber 211;

[0101] The material discharging control assembly controls the movement of the receiving plate 21 and the supporting plate 24 respectively.

[0102] The detection cavity 211 is formed by digging grooves in the receiving plate 21, and the support plate 24 and the receiving plate 21 can be independently controlled to move, so that the round rod 4 can be moved to different areas respectively, so as to achieve the classification of good products and waste products.

[0103] In this embodiment, the pressing assembly includes:

[0104] The top pressure cylinder 221 is vertically downwardly arranged just above the detection chamber 211;

[0105] A pressing frame 222 is telescopically connected to the pressing cylinder 221;

[0106] At least two pressing columns 223 are vertically downwardly arranged on the pressing frame 222;

[0107] The pressing rod 224 is connected to the lower end of the pressing column 223 and is located directly above the pressing hole 212 . As the pressing cylinder 221 extends, the pressing hole 212 passes through the pressing hole 212 to apply pressing force to the round rod 4 in the detection cavity 211 toward the support plate 24 .

[0108] The pressing rod 224 can fix the round bar 4, reduce the bending deformation when the push rod 32 is used to push the round bar 4 for measurement, and after being confirmed as a waste product, the round bar 4 can be smoothly pushed into the waste box 25.

[0109] In this embodiment, the discharge control component includes:

[0110] The good quality cylinder 231, the telescopic end is fixedly connected to the receiving plate 21;

[0111] The sliding direction of the good product horizontal sliding assembly 232 is the same as the extension and contraction direction of the good product cylinder 231;

[0112] The waste cylinder 233, the support plate 24 is fixedly connected to the telescopic end of the waste cylinder 233.

[0113] The movements of the accommodating plate 21 and the supporting plate 24 are controlled respectively by two independent cylinders, so that the closed accommodating cavity formed by the supporting plate 24 and the accommodating plate 21 is opened.

[0114] In this embodiment, the detection mechanism 3 includes:

[0115] A horizontal displacement unit 31, whose displacement direction is parallel to the discharge port 113 of the step loading unit 1;

[0116] A push rod 32, one end of which is slidably connected to the through hole 114 passing through the material box 11 and the material box 11, and the other end of which is slidably connected to the horizontal displacement mechanism;

[0117] The retractable distance sensor 33 is arranged on the horizontal displacement unit 31 , and the detection column is connected to the push rod 32 .

[0118] The two ends of the horizontal displacement unit 31 are provided with limit posts 34. By moving the horizontal displacement unit 31 by a certain distance, the amount of movement of the retractable distance sensor 33 due to the round rod 4 can be known, and the difference between the two can be used to calculate the actual length of the round rod 4.

[0119] The round rod 4 feeding and feeding detection mechanism 3 of this embodiment is used as follows: all the round rods 4 that need to be fed and detected are placed on one side of the partition 17 of the material box 11. Under the action of gravity, the round rods 4 slide along the bottom plate 111 to the front of the material box 11 and fall to the upper end of the slide plate 13 at the bottom.

[0120] Start the step displacement cylinder 14, and the round rods 4 are lifted one by one until they fall to the top. At this time, the guide cylinder 19 is controlled to extend to cover the outside of the round rod 4, and then the horizontal displacement unit 31 is controlled to move from the left to the right until it contacts the limit column 34. In this process, the push rod 32 pushes the round rod 4 toward the detection chamber 211 until the end face of the round rod 4 contacts the bottom of the detection chamber 211. At this time, the round rod 4 no longer moves, and the top pressure cylinder 221 is controlled at this time. However, because the horizontal moving unit continues to move, the push rod 32 pushes the detection rod of the retractable distance sensor in the opposite direction to retract. In this way, the fixed displacement of the horizontal moving unit and the detection amount of the retractable distance sensor 33 can be used to know whether the length of the round rod 4 meets the standard.

[0121] If the length is up to standard, the push cylinder 221 is controlled to retract, the push rod 224 is withdrawn from the receiving plate 21, and then the good cylinder 231 is controlled to extend, so that the receiving plate 21 moves forward, so that the receiving plate 21 is separated from the support plate 24, the receiving cavity is exposed, and the round rod 4 is sent out of the support plate 24 and locked in the area. If the length is not up to standard, the reject cylinder 233 is directly controlled to extend, and the round rod 4 is no longer supported by the support plate 24, and falls into the reject box 25 under the action of gravity and the push cylinder 221.

[0122] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the utility model.
