DETAILED DESCRIPTION

[0027] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only configured to explain the present invention and are not configured to limit the present invention. For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present invention by illustrating examples of the present invention.

[0028] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of the present invention. In the description of the present invention, it should also be noted that, unless otherwise clearly specified and limited, the terms "installation" 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 be directly connected or indirectly connected. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0029] like Figures 1 to 8 As shown, an embodiment of the present invention provides a bar material feeding device, comprising a frame 1, a feeding frame 4 and a pushing mechanism 9. The device is intended to improve the flexibility and versatility of the equipment to meet the conveying requirements of bars of different specifications.

[0030] The pushing mechanism 9 is installed at the end of the loading rack 4, and the loading rack 4 is slidably connected to the upper surface of the frame 1 through two linear slide rails, so that the loading rack 4 can move smoothly and accurately in the length direction of the frame 1. A rack 13 is fixedly installed in the middle of the upper surface of the frame 1, and a motor module 2 is fixedly installed on one side of the loading rack 4. The output end of the motor module 2 is fixedly connected to a spur gear 3, and the spur gear 3 is meshed with the rack 13 for transmission.

[0031] When the motor module 1 2 receives a start signal from the control module (not explicitly shown in the figure), it starts to rotate and drives the spur gear 3 to rotate synchronously. Since the spur gear 3 is tightly meshed with the rack 13, when the spur gear 3 rotates, it moves along the tooth surface of the rack 13. This movement is converted into a linear movement of the loading rack 4 on the frame 1, thereby sending the pushing mechanism 9 to or out of the loading position.

[0032] The pushing mechanism 9 includes a driving assembly and a base frame 18. An end seat 5 is provided at one end of the loading frame 4, and a connecting frame 8 is hinged at one end of the end seat 5. A hydraulic cylinder three 15 is hinged inside the loading frame 4, and the other end of the hydraulic cylinder three 15 is hinged to the connecting frame 8. Two groups of hydraulic cylinders two 14 are hinged on one side of the bottom of the base frame 18, and the other ends of the two groups of hydraulic cylinders two 14 are hinged at the bottom of the connecting frame 8. A top plate 19 is provided on the base frame 18, and both sides of the upper surface of the top plate 19 are slidably connected to the supporting seats 16 through guide rails 21. The driving assembly includes a motor module three 28 located in the middle of the two groups of supporting seats 16, and the motor module three 28 is fixed on the crossbeam 26 of the base frame 18. A connecting seat 27 is provided in the middle of the bottom of the supporting seat 16, and a lead screw nut is fixed on one side of the connecting seat 27. An output end is provided on each side of the motor module three 28, and each output end is fixedly connected with a lead screw 29 passing through the corresponding lead screw nut.

[0033] When the spacing of the support seats 16 needs to be adjusted to accommodate bars of different diameters, the control module sends a start signal to the motor module three 28 according to the information input by the user. The signal contains the number of pulses (or steps) that control the rotation angle and the direction of rotation. The number of pulses determines the distance that the support seats 16 need to move, while the direction of rotation determines whether the support seats 16 are close to each other or away from each other. After receiving the signal, the motor module three 28 will synchronously rotate the two sets of screw rods 29 at its output end. Since the screw rod 29 is tightly matched with the screw nut, when the screw rod 29 rotates, it will drive the support seat 16 to move linearly along the guide rail 21, thereby adjusting the spacing between the two support seats 16.

[0034] When the support 16 adjusts the spacing according to the diameter of the bar, the center axis of the bar will also change accordingly. If this change is not corrected, it may cause the bar to deviate from the feeding port of the processing equipment, thereby affecting the normal feeding. Therefore, while the spacing of the support 16 is adjusted, the control module will calculate the possible change in the center axis of the bar according to the diameter of the bar and the expected processing position. Then, by sending instructions to the hydraulic cylinder 2 14 and the hydraulic cylinder 3 15, their working parameters (such as telescopic length, pressure, etc.) are adjusted, and the position of the base frame 18 is adjusted, thereby changing the relative position of the bar to compensate for the change in the center axis of the bar.

[0035] A level sensor is provided on the lower surface of the top plate 19 to monitor the level or posture of the entire pusher mechanism 9 in real time. Once a change in level is detected, the level sensor will immediately convert this information into an electrical signal and transmit it to the control module. After receiving the signal from the level sensor, the control module will analyze the data and calculate the necessary adjustment amount. Then, it will send instructions to hydraulic cylinder 2 14 and hydraulic cylinder 3 15 to adjust their working parameters to correct the tilt or offset of the pusher mechanism 9 while ensuring that the center axis of the bar remains unchanged, so as to prevent the bar from rolling down due to the tilt of the pusher mechanism 9.

[0036] Sprockets 17 are installed at both ends of the base frame 18, and one end of one of the sprockets 17 is fixedly connected to a universal joint 10. The sprockets 17 form a closed-loop transmission system through a chain 24, and a push plate 22 is fixedly installed on the chain 24. The push plate 22 is located in the middle of the two sets of support seats 16. The upper surface of the top plate 19 is provided with a protruding support rib 20, and the support rib 20 corresponds to the roller on the chain 24. The function of the support rib 20 is to provide additional support for the chain 24, avoid direct contact between the chain 24 and the top plate 19, reduce friction and vibration and noise of the chain 24 during operation. The connection between the two ends of the support rib 20 and the upper surface of the top plate 19 is transitioned with a slope 23. It helps the chain 24 to smoothly cross the support rib 20 when starting, reducing the starting resistance. A motor module 2 12 is provided on one side of the loading frame 4, and the output end of the motor module 2 12 is fixedly connected to a universal joint 2 11. Since the position of the pusher mechanism 9 changes frequently, the universal joint 2 11 and the universal joint 1 10 are splined to adapt to different installation angles and transmission requirements. The design of the universal joint allows the angle to change within a certain range, thereby ensuring that the power can be stably and continuously transmitted to the sprocket 17.

[0037] When the motor module 2 12 is started, the universal joint 2 11 transmits power to the universal joint 1 10, thereby driving the sprocket 17 to rotate, and the rotation of the sprocket 17 drives the chain 24 to circulate on the chassis 18. As the chain 24 runs, the push plate 22 fixed on the chain also moves accordingly, thereby pushing the bar material on the support seat 16 to realize the transportation of the bar material. The pushing end of the push plate 22 is equipped with a roller 25, which helps to buffer the instantaneous rigid impact and reduce the friction between the push plate 22 and the bar material. Several groups of support rollers 30 are installed on one side of the two groups of support seats 16, and the two rows of support rollers 30 are distributed in an eight-shaped shape. The obliquely arranged roller row can better adapt to bars of different diameters, and at the same time help to reduce the friction between the support seat 16 and the bar material, making the pushing process smoother.

[0038] In order to prevent the bar from falling during the transportation process, the pressing mechanism 7 is connected to the connecting frame 8 by an articulated manner so that it can move toward the pushing mechanism 9. The pressing mechanism 7 includes a support frame 31, one end of which is hinged to the top of the connecting frame 8, and the other end of the support frame 31 is provided with a mounting seat 32, and the bottom of the mounting seat 32 is hinged with a pressing assembly. A hydraulic cylinder 6 is hinged to one side of the support frame 31, and the other end of the hydraulic cylinder 6 is hinged to the top of the end seat 5. The pressing assembly includes two groups of pressing seats 34, and the pressing seats 34 are connected by two groups of V-shaped seats 33. Semicircular grooves 36 are provided at both ends of the bottom of the mounting seat 32, and these grooves are used to match the semicircular head at the top of the pressing seat 34. A rotating shaft 37 is provided at the center of the groove 36, and a center hole adapted to the rotating shaft 37 is provided at the top semicircular head of the pressing seat 34, so that the pressing seat 34 can rotate to a certain extent on the mounting seat 32. A plurality of pressing rollers 35 are installed at the bottom of the two groups of pressing seats 34. The two rows of pressing rollers 35 are arranged in an inverted figure eight shape to reduce the friction between the pressing seats 34 and the bar material, making the pushing process smoother.

[0039] When the hydraulic cylinder 16 is activated, it pushes the pressing mechanism 7 to move toward the pushing mechanism 9. As the pressing mechanism 7 moves, the pressing seat 34 and the pressing roller 35 thereon gradually contact and press the bar material on the supporting seat 16. The inverted eight-shaped distribution of the pressing roller 35 can better adapt to bars of different diameters, help to better wrap and press the bar material, and prevent it from deflecting or jumping during the conveying process.

[0040] According to the embodiments of the present invention as described above, these embodiments do not describe all the details in detail, nor do they limit the invention to specific embodiments. Obviously, many modifications and changes can be made based on the above description. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can make good use of the present invention and the modified use based on the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
