During the production process, the cut and segmented rebar needs to be packaged. Currently, this packaging process requires a certain amount of rebar to be packed.

[0003] In the invention patent document with announcement number CN114713744B, an automatic conveying mechanism for hot-rolled steel bar production is disclosed, which relates to the field of steel bar technology, including a conveying shell and a support frame fixedly connected to the shell, the shell is horizontally arranged on the support frame, a feed port is opened on the surface of the shell, a guide plate is fixedly connected to the support frame, the distance between the guide plate and the feed port is a feed channel, a single feeding mechanism and a discharging mechanism for taking out a single material are also provided in the shell, and a driving component for driving the single feeding mechanism is installed on the shell. After the cut steel bars are brought from the guide plate to the feed channel, the servo motor is turned on, the gear will drive the toothed disc to rotate, and the rotating roller starts to rotate and the clamping hole will grab the steel bars. When the steel bars rise to a certain angle, the steel bars will fall from the feeding strip hole into the semicircular arc tube.

[0004] However, in the above scheme, the hydraulic push rod installed at one end of the semicircular arc tube requires a long pushing distance to push out the steel bars because most of the steel bars are slender. This causes, firstly, the speed of the hydraulic push rod, cylinder, electric cylinder and other telescopic equipment to be affected by the pushing length, making it difficult to perform high-frequency pushing actions. Secondly, when these telescopic equipment have a longer working stroke, the equipment size itself is also longer, which seriously occupies equipment space and needs to be improved. Utility Model Content

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Reference Figure 1-5 The utility model provides a conveying device for steel bar production, including a conveying drum 1. The specific structure of the conveying drum 1 refers to the invention patent with the announcement number CN114713744B. A semicircular arc tube 2 for receiving steel bars is installed inside the conveying drum 1. A crank slider mechanism 3 is provided at the end of the semicircular arc tube 2. The crank slider mechanism 3 includes a crank 301, a first slide 302, and a first slide bar 303 connected in sequence. The input end of the crank 301 is connected to the working end of the driving motor. The driving motor drives the crank 301 to swing back and forth in a circle, and the crank 301 drives the first slide bar 303 to perform linear reciprocating motion in the first slide 302.

[0026] The end of the first slide bar 303 away from the crank 301 extends into the semicircular arc tube 2. Every time the steel bar falls from the conveying cylinder 1 into the semicircular arc tube 2, the first slide bar 303 moves and hits a steel bar that falls into the semicircular arc tube 2, sending the steel bar out of the semicircular arc tube 2 without the need for a long telescopic stroke.

[0027] A force transmission mechanism 4 corresponding to the crank slider mechanism 3 is installed axially in a sliding manner inside the semicircular arc tube 2 near one end of the crank slider mechanism 3. The force transmission mechanism 4 is used to transmit the external force applied by the crank slider mechanism 3 to the steel bar, which can further reduce the stroke length of the crank slider mechanism 3.

[0028] Specifically, the force transmission mechanism 4 includes a knocking block 401, a slider 402, and a slide groove 406. The side wall of the semicircular arc tube 2 is processed with a slide groove 406. Sliders 402 are set at both ends of the knocking block 401. The slider 402 is slidably installed in the slide groove 406. When the steel bar enters the steel bar inlet 103 from the guide plate 104, and enters the semicircular arc tube 2 from the steel bar inlet 103 through the strip feed hole, the first slide rod 303 hits the knocking block 401. The knocking block 401 cooperates with the slider 402 and the slide groove 406, slides axially and continues to hit the steel bar to send the steel bar out.

[0029] Then knock block 401 resets, waits for the next one to just enter and fall in the semicircular arc tube 2.

[0030] The force transmission mechanism 4 also includes a second slide bar 403, a second slide seat 404, and a spring 405. A second slide seat 404 is provided at the end of the slider 402 away from the knocking block 401. The second slide seat 404 is slidably mounted on the second slide bar 403. One end of the second slide bar 403 is fixedly connected to the conveying cylinder 1. The second slide bar 403 and the second slide seat 404 cooperate to assist the sliding of the knocking block 401 and improve the sliding stability of the knocking block 401.

[0031] In addition, the striking block 401 is suspended in the semicircular arc tube 2 and has no direct contact with the semicircular arc tube 2, thereby reducing friction.

[0032] The surface of the second slide rod 403 is sheathed with a spring 405, which is located between the conveying cylinder 1 and the second slide seat 404. The second slide seat 404 is retractably slidably sheathed on the second slide rod 403 through the spring 405. The elastic force of the spring 405 drives the knocking block 401 to reset after each collision.

[0033] As needed, the sliding movement of the knocking block 401 can be shortened, thereby shortening the cycle time of the linear reciprocating motion of the knocking block 401, thereby increasing the motion frequency and meeting the funny conveying requirements.

[0034] The conveying cylinder 1 includes a cylinder body 101 and a rotating roller 102 installed coaxially. The rotating roller 102 is rotatably installed in the cylinder body 101. The rotating roller 102 is processed with feed strip holes, and the feed strip holes are radially distributed. A steel bar inlet 103 is provided on the side of the cylinder body 101, and a guide plate 104 is provided at the end of the steel bar inlet 103 away from the cylinder body 101. A top opening 202 corresponding to the rotating roller 102 is provided at the top of the semicircular arc tube 2. The feed strip holes are used to maintain dynamic communication between the steel bar inlet 103 and the top opening 202.

[0035] The semicircular arc tube 2 includes a tube body 201, and a top opening 202 is located at the top of the tube body 201. A roller 203 for conveying steel bars is arranged inside the tube body 201. There are multiple rollers 203, and the axes of the multiple rollers 203 are perpendicular to the axis of the semicircular arc tube 2, and the rollers 203 are horizontally arranged. The rollers 203 are evenly arranged inside the semicircular arc tube 2, and the rollers 203 are rotatably connected to the tube body 201. When the steel bars fall into the tube body 201 from the feed strip hole, they fall directly on the rollers 203, and then slide out on the rollers 203 under the impact of the knocking block 401. The friction of the steel bars in the semicircular arc tube 2 is reduced by the rollers 203, thereby reducing the requirements for the knocking force of the crank slider mechanism 3.

[0036] Working principle: When in use, the rotating roller 102 rotates, and the steel bars just enter from the guide plate 104, pass through the steel bar inlet 103, enter into different feed strip holes one by one, and then fall into the semicircular arc tube 2. The crank slider mechanism 3 is adjusted according to the time when the steel bars fall into the semicircular arc tube 2, and the frequency of the first slide bar 303 hitting the knocking block 401 is controlled. Then, the knocking block 401 transmits force to knock the steel bars, and the steel bars slide on the roller shaft 203 and easily slide out of the semicircular arc tube 2, which is convenient for improving the transportation efficiency of the steel bars.
