DETAILED DESCRIPTION

[0026] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0027] like Figures 1 to 6As shown, the present invention provides an embodiment of a steel bar unloading device, including a base 1, a support frame 2, a material receiving platform 3 and a material blocking mechanism 4, wherein the support frame 2 is arranged above the base 1, and the material receiving platform 3 is slidably mounted on the support frame 2, and when unloading finished steel bars, the finished steel bars can be placed on the material receiving platform 3, and the arrangement of the material receiving platform 3 is convenient for placing various special-shaped steel bars, and there is no need to adjust the shape and position of the steel bars to meet the unloading requirements of different steel bars, and a screw slide module 5 is arranged below the material receiving platform 3, and the material receiving platform 3 is fixedly connected to the slide of the screw slide module 5, and the material receiving platform 3 is driven to move back and forth by the screw slide module 5, thereby driving the steel bars to move;

[0028] The material blocking mechanism 4 is mounted above the material receiving platform 3, and the material blocking mechanism 4 has a bracket 6, a baffle 7, a guide plate 8 and a lifting device 9. Both ends of the bracket 6 are mounted on the support frame 2, the guide plate 8 is slidably installed on the bracket 6, and the baffle 7 is fixed on the guide plate 8. The setting of the guide plate 8 enables the baffle 7 to move back and forth along the height direction of the bracket 6 to prevent the baffle 7 from tilting during the movement. The baffle 7 is vertically arranged to the material receiving platform 3, and the material receiving platform 3 can pass under the baffle 7. The lifting device 9 is installed on the bracket 6, and the lifting device 9 can lift the baffle 7.

[0029] The working principle of the material blocking mechanism 4 is as follows: when it is necessary to unload the steel bars on the material receiving platform 3, the material receiving platform 3 is first driven to move toward the baffle 7 by the screw slide module 5. When the material receiving platform 3 is close to the baffle 7, the guide plate 8 and the baffle 7 are lifted by the lifting device 9. At this time, there is a gap between the baffle 7 and the material receiving platform 3. When the material receiving platform 3 continues to move, it can drive the steel bars to pass under the baffle 7. When the material receiving platform 3 drives the steel bars to pass under the baffle 7, the guide plate 8 and the baffle 7 are dropped by the lifting device 9. At this time, the baffle 7 is in contact with the upper surface of the material receiving platform 3, and then the screw is used. The slide module 5 drives the material receiving platform 3 to move in the opposite direction, so that the material receiving platform 3 is reset. During the resetting process, the material receiving platform 3 will drive the steel bars to move toward the baffle 7. Since the baffle 7 is in contact with the upper surface of the material receiving platform 3 at this time, the material receiving platform 3 can pass under the baffle 7, and the steel bars placed on the material receiving platform 3 are blocked by the baffle 7, so that the steel bars are detached from the material receiving platform 3, completing the unloading of the steel bars. Through the cooperation of the baffle 7 and the material receiving platform 3, special-shaped steel bars of various shapes can be unloaded, and there is no need to sort the shape of the steel bars, which effectively improves the application scope of the steel bar unloading equipment.

[0030] The lifting device 9 includes a top block 10, a shift block 11, a rotating shaft 12 and a torsion spring seat 13. The torsion spring seat 13 is fixed to the bracket 6. One end of the rotating shaft 12 is mounted on the torsion spring seat 13. The other end of the rotating shaft 12 is fixedly connected to the top block 10. The torsion spring seat 13 allows the top block 10 to be reset in time after the action. The lower end of the guide plate 8 abuts against the top block 10, so that the top block 10 can lift the guide plate 8 upward when it rotates upward. The top block 10 is hinged to the shift block 11. The end of the shift block 11 close to the top block 10 has a contact plane 14, which can abut against the top block 10. The contact plane 14 abuts against the top block 10, so that the shift block 11 can drive the top block 10 to rotate at the same time when it rotates, and a push plate 15 is provided on the material receiving platform 3 corresponding to the shift block 11. The front end of the push plate 15 extends out of the edge of the material receiving platform 3, so that the baffle 7 can first contact the shift block 11 and push the shift block 11 when moving forward, and the rear end of the push plate 15 is retracted into the edge of the material receiving platform 3, so that the baffle 7 can be separated from the shift block 11 in time, and the push plate 15 is parallel to the moving direction of the material receiving platform 3, and the push plate 15 can push the shift block 11 to rotate with the rotating shaft 12 as the rotation center.

[0031] The working principle of the lifting device 9 is as follows: when the material receiving platform 3 moves toward the baffle plate 7, the front end of the push plate 15 first pushes the shift block 11, so that the shift block 11 rotates in the forward direction of the push plate 15 with the rotating shaft 12 as the center. At this time, the contact plane 14 of the shift block 11 abuts against the top block 10, and the shift block 11 and the top block 10 remain perpendicular to each other, so that the shift block 11 drives the top block 10 to lift upward during rotation, and then the guide plate 8 and the baffle plate 7 are lifted. After the baffle plate 7 is lifted, the material receiving platform 3 continues to move forward, and the steel bars on the material receiving platform 3 can pass smoothly from under the baffle plate 7. At this time, the material receiving platform 3 continues to move forward, so that the rear end of the push plate 15 is separated from the shift block 11. At this time, the shift block 11 and the top block 10 rotates in the opposite direction and resets under the action of gravity and the torsion spring, so that the baffle 7 falls to abut against the upper surface of the material receiving platform 3, and then the material receiving platform 3 drives the steel bars to retreat and reset. When the material receiving platform 3 moves in the opposite direction, the rear end of the push plate 15 first contacts the shift block 11. At this time, the shift block 11 rotates in the opposite direction with the rotating shaft 12 as the center. At this time, the contact plane 14 of the shift block 11 is disengaged from the top block 10, so that the shift block 11 is parallel to the top block 10. At this time, the push plate 15 moves along the lower surfaces of the shift block 11 and the top block 10 to prevent the top block 10 from lifting the baffle 7, so as to ensure that when the material receiving platform 3 retreats and resets, the baffle 7 can smoothly block the steel bars and unload the steel bars from the material receiving platform 3. By setting the lifting device 9, the material receiving platform 3 can drive the steel bars to pass under the baffle 7 when moving forward; when the material receiving platform 3 is reset backward, the baffle 7 can always fall on the material receiving platform 3 and abut against the material receiving platform 3, blocking the steel bars and completing the unloading operation of the steel bars.

[0032] In other embodiments, a cylinder or an electric push rod can also be used to drive the baffle 7 to move up and down. However, the use of a cylinder or an electric push rod greatly increases the cost of the equipment on the one hand, and on the other hand, the cylinder and the electric push rod are relatively precise and prone to malfunctions and false touches, resulting in failure in steel bar feeding. The present embodiment adopts a mechanical linkage method with a simple structure and stable connection, which improves the stability of the equipment during operation.

[0033] A shelf 19 is also provided below the support frame 2. After the steel bars are unloaded from the material receiving platform 3, they directly fall onto the shelf 19. Multiple steel bars are transported to the shelf 19 in sequence through the material receiving platform 3 to achieve stacking of the steel bars. Multiple positioning rods 20 are provided on the shelf 19. The positioning rods 20 are used to fix the steel bars to prevent the stacked steel bars from slipping. The positioning rods 20 are plugged into the shelf 19 to facilitate adjustment of the position of the positioning rods 20 so that the positioning rods 20 can fix special-shaped steel bars of different shapes. The bottom of the shelf 19 is provided with moving wheels 21. When the stacking of the steel bars is completed, the shelf 19 is removed from the bottom of the support frame 2 by moving the shelf 19 to facilitate the transfer of the stacked steel bars.

[0034] A plurality of lifting cylinders 18 are installed on the base 1, and the piston rods of the lifting cylinders 18 are connected to the support frame 2. The lifting cylinders 18 can lift the support frame 2. When more steel bars need to be stacked, the support frame 2 is lifted by the lifting cylinders 18. When the support frame 2 is lifted, the material receiving platform 3 and the material blocking mechanism 4 are also lifted to facilitate lifting the steel bars, so that the steel bars can be stacked on the shelf 19 at a higher place, further improving the use scope of the material receiving platform 3.

[0035] A rodless cylinder 16 and a connecting plate 17 are also provided at both ends of the bracket 6. The rodless cylinder 16 is fixed on the support frame 2, and the connecting plate 17 is installed on the cylinder body of the rodless cylinder 16. The connecting plate 17 is fixedly connected to the bracket 6. When the finished steel bars are unloaded, the length and width of different finished products are different. At this time, the bracket 6 is driven to move by the rodless cylinder 16, and the position of the blocking mechanism 4 can be adjusted, and then the position of the baffle 7 can be adjusted, so that the baffle 7 can adjust the unloading position of the steel bars when blocking the steel bars, so that the steel bars can be accurately dropped onto the shelf 19. In other embodiments, the bracket 6 can also be directly installed on the slide rail, and the position of the bracket 6 can be adjusted manually, but manual adjustment is time-consuming and labor-intensive. Therefore, the method of using the rodless cylinder 16 to drive the bracket 6 to move in this embodiment is the optimal embodiment.
