It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0018] In order to illustrate the technical solution described in the present utility model, the following is illustrated through specific embodiments.

[0019] Only the parts related to the embodiments of the present utility model are shown for the convenience of description.

[0020] Combined with Figures 1 - 3 As shown, the steel bar feeding device includes a feeding rack, a feeding mechanism, and a traction mechanism 2 arranged in sequence. The traction mechanism includes a traction table 21. A pair of mounting plates 22 are rotatably arranged on the traction table 21. The two mounting plates 22 are arranged crosswise. Arc-shaped guide grooves 23 are opened on both sides of the traction table 21. A pair of upper and lower traction wheels 24 are rotatably arranged on the mounting plates 22. A rotating shaft 25 is arranged on each traction wheel 24. The upper rotating shafts all pass through the arc-shaped guide grooves 23 on the same side and are provided with driven sprockets 26. A driving motor 27 is arranged on the traction table 21. A driving shaft of the driving motor 27 is provided with a driving double-layer sprocket (blocked in the figure). Chains 29 are sleeved between the driving double-layer sprocket and the driven sprockets 26 respectively. A pressing cylinder 230 is arranged on the top of the traction table 21. A pair of linkage rods 231 are rotatably arranged on a driving shaft of the pressing cylinder 230. The linkage rods 231 are respectively rotatably connected to the two mounting plates 22.

[0021] As one of the most commonly used materials in building structures, steel bars are equivalent to the skeleton of the human body in the building body, and their role is particularly significant. Therefore, steel bars are an essential part of the building, especially in large public buildings, where the selection and design content of steel bars are relatively large.

[0022] Before the steel bars are used, this feeding device can be used to send the steel bars to the cutting and processing mechanism one by one and in an orderly manner, and the cutting and processing mechanism cuts the steel bars into the required lengths for subsequent use. The processing mechanism is not the key content of this device, so it will not be described in detail here.

[0023] In this structure, the steel bar feeding device is composed of a feeding rack, a feeding mechanism, and a traction mechanism. Before processing the steel bars, first place a certain number of steel bars on the feeding rack according to requirements, and then feed the steel bars on the feeding rack onto the feeding mechanism one by one. The feeding mechanism conveys the steel bars on it towards the traction mechanism for a certain distance. The traction mechanism first clamps the steel bar and then pulls it to the processing mechanism for processing.

[0024] A pair of mounting plates are rotatably provided on the traction table, and upper traction wheels and lower traction wheels are respectively rotatably provided at both ends of the mounting plates. Before the steel bars are tractioned, there is a gap between the upper and lower sets of traction wheels. When the front end of the steel bar is conveyed by the feeding mechanism between the upper and lower sets of traction wheels, the pressing cylinder drives two linkage rods to move downward, and the linkage rods push the two mounting plates to rotate downward. At this time, the upper and lower sets of traction wheels rotate towards each other until the front end of the steel bar is clamped. Immediately afterwards, the driving motor drives the double-layer sprocket to rotate. Under the linkage of the traction chain, the two upper traction wheels rotate and traction the steel bar towards the processing mechanism. At the same time, the feeding mechanism also continues to feed the steel bar. Under the dual action of the feeding mechanism and the traction mechanism, the steel bar is more stable during the feeding process.

[0025] In this structure, when the two mounting plates are rotating, the rotating shafts on the upper and lower sets of traction wheels slide in the corresponding arc-shaped guide grooves respectively. Under the action of the rotating shafts, the arc-shaped guide grooves play a role of guiding and limiting, making the mounting plates more stable during the rotation process, and making the traction effect of the traction mechanism on the steel bar better.

[0026] In this device, such as Figure 1 , Figure 4 , the feeding mechanism includes a feeding frame 3. A plurality of feeding wheels 4 are rotatably provided on the feeding frame 3. A fixing frame 5 is provided on the feeding frame 4. A plurality of lifting cylinders 6 are provided on the fixing frame 5. A lifting seat 7 is provided on the driving shaft of the lifting cylinder 6. A pressing wheel 8 is rotatably provided in the lifting seat 7, and the pressing wheel 8 and the corresponding feeding wheel 4 are arranged up and down. A driving mechanism for driving all the feeding wheels 4 to rotate simultaneously is also provided on the feeding frame 3.

[0027] When the steel bar is loaded from the feeding rack onto the feeding mechanism, that is, the steel bar is loaded onto a plurality of feeding wheels. Then all the lifting cylinders simultaneously drive the corresponding lifting seats to move towards the steel bar until the pressing wheel presses down on the steel bar. Finally, all the feeding wheels rotate simultaneously under the drive of the driving mechanism, and the steel bar moves towards the traction mechanism. During the feeding process of the steel bar, the pressing wheel always presses it tightly, improving the stability of the steel bar during feeding.

[0028] And the driving mechanism includes a double-layer rotating sprocket 9 installed on the shaft rod of the feeding wheel 4. A driving chain 10 is sleeved between two adjacent double-layer rotating sprockets 9. A driving motor 11 for driving the feeding wheel 4 at the end to rotate is provided on the feeding frame.

[0029] In this structure, such as Figure 4, a driving sprocket 111 is provided on the driving shaft of the driving motor 11, and a matching linkage chain 112 is sleeved between the driving sprocket 111 and the other rotating sprocket of the double-layer rotating sprocket on the end feeding wheel. When the driving mechanism is to be used to drive all the feeding wheels to rotate simultaneously, the driving motor drives the driving sprocket to rotate. Under the linkage of the linkage chain, the double-layer rotating sprocket on the end feeding wheel rotates. Under the common linkage of all the driving chains, all the feeding wheels rotate synchronously, thereby realizing the feeding of the steel bars.

[0030] As a preferred structure, such as Figure 1 , Figure 5 , the feeding rack includes a base 101, and a number of inclined loading racks 102 are provided on the base 101. A baffle 103 is formed at the bottom of the loading rack 102. A pushing plate 104 is slidably provided on the side wall of each baffle 103. A linkage shaft 105 is rotatably provided on the base 101. A short block 106 is provided on the linkage shaft 105 corresponding to each pushing plate 104. An intermediate block 107 is rotatably provided on the short block 106. The intermediate block 107 is rotatably connected to the pushing plate 104. A rotating cylinder 108 is also rotatably provided on the base 101. A rotating block 109 is rotatably provided on the driving shaft of the rotating cylinder 108. The rotating block 109 is fixed to the linkage shaft 105.

[0031] In addition, a guide plate 12 is provided at the top of the baffle 103 facing the feeding wheel. Before processing the steel bars, first place a certain number of steel bars on the loading rack as required, and the steel bars are blocked by the baffles. When the steel bars are to be loaded onto the feeding mechanism one by one and orderly, first the rotating cylinder drives the linkage shaft to rotate, and all the short blocks on the linkage shaft rotate synchronously. Under the linkage of the intermediate blocks, all the pushing plates jointly push up the lowermost steel bar on the loading rack. The steel bar moves upward along the height of the baffle until the steel bar is pushed onto the guide plate. Since the guide plate is inclined towards the feeding rack, the steel bar finally falls onto a number of feeding wheels.

[0032] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
