DETAILED DESCRIPTION

[0025] A preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.

[0026] See also Figure 1 and 2 The utility model provides a bar material anti-congestion transfer mechanism, which is arranged between the discharge flow channel 1 and the loading turntable 3, and is used to transfer the material (i.e., bar material) from the discharge flow channel 1 of the vibrating plate to the material trough 31 corresponding to the loading turntable 3 one by one. The material is a divided bar material composed of a large diameter section and a small diameter section. The loading flow channel 1 is tiltedly arranged beside the feed port 211 of the transfer mechanism 2, and the lower end of the loading flow channel 1 is connected to the feed port 211 of the transfer mechanism 2. The inclined angle between the loading flow channel 1 and the horizontal plane is less than 30°, so that the material can be transported downward along the loading flow channel 1 by its own weight and at a certain speed. The loading turntable 3 is rotatably arranged at the lower end of the transfer mechanism 2, and the material trough 31 thereon is used to receive the materials falling one by one from the discharge port 212 of the transfer mechanism 2. The utility model provides two embodiments of the transfer mechanism 2 for illustration.

[0027] Embodiment 1.

[0028] See also Figure 3, three groups of buffer components 21 are arranged at intervals inside the transfer trough 20 along the conveying direction of the material, and the three groups of buffer components 21 divide the interior of the transfer trough 20 into a loading area A, a buffer area B and a discharging area C arranged in sequence, and the upper end of each group of buffer components 21 is rotatably connected to the two side walls of the transfer trough 20 parallel to the conveying direction, so as to realize the connection and closing between the loading area A, the two buffer areas B and the discharging area C; the feed port 201 is arranged in the loading area A, and the bottom of the loading area A is provided with a pusher component 22 for pushing the material entering the loading area A into the buffer area B; the discharge port 202 is only for a single material to pass through and is arranged at the bottom of the discharging area C. The pusher component 22 includes a pusher 221 arranged in the horizontal direction, and a driving component 222 arranged outside one end of the bottom of the loading area A of the transfer trough 20 for driving the pusher 221 to reciprocate in the conveying direction. The pusher 221 is a tooth-shaped structure. A through hole 206 matching the pusher 221 is formed on a side wall of one end of the transfer trough 20 close to its feed port 201 .

[0029] Each set of buffer components 21 includes a buffer 211 and a rotating shaft 212. The upper end of the buffer 21 is rotatably connected to the transfer trough 20 through the rotating shaft 212, and the lower end of the buffer 21 is close to the bottom surface of the transfer trough 20. That is, under the action of external force, the lower end of the buffer 211 can swing around the upper end around the rotating shaft 212, thereby realizing the connection and closing between the loading area A, the buffer area B and the unloading area C.

[0030] Furthermore, each set of buffer members 211 is a ""-shaped structure bent toward one side of the conveying direction, and the end of its horizontal section is rotatably connected to the transfer trough 20 through a rotating shaft 212, so that the end of its vertical section is inclined away from the conveying direction.

[0031] According to the force decomposition, the lower end of the buffer 211 of the ""-shaped structure in the natural state is always inclined toward the side away from the material conveying direction, thereby forming resistance to the material entering each zone, and then a certain thrust is required to push its lower end toward the side of the material conveying direction, so that its lower end and the bottom surface of the transfer trough 20 form an opening allowing the material to pass through, and after the thrust disappears, it relies on self-repositioning to block the free state of the bar material to prevent it from entering the next zone, thereby ensuring that the material will not be crowded in the unloading zone C. It can be understood that the thrust comes from the creeping force generated between the materials when the pushing assembly 22 pushes the material in the loading zone A to a buffer zone B close to it.

[0032] Furthermore, the transfer trough 20 also includes a horizontally arranged conveying channel 203, a "V"-shaped buffer channel 204 connected to the conveying channel 203, and a material discharge channel 205 arranged at the lower end of the buffer channel 204 and connected thereto, two of the three groups of buffer components 21 are respectively arranged at the front and rear ends of the conveying channel 203, and the other group of buffer components 21 is arranged at the end of the buffer channel 204. The bottom surface of the material discharge channel 205 close to one side of the buffer channel 203 is an inclined surface facing the conveying direction and tilted downward, so that the material coming down from the second buffer zone quickly falls into the trough 31 of the loading turntable 3.

[0033] Specifically, the arrangement of the three flow channels enables the bottom surface of the transfer trough 20 to form a horizontal surface 2031, a first inclined surface 2042, and a second inclined surface 2051 which are connected in sequence, and the inclination angle of the second inclined surface 2051 is greater than the inclination angle of the first inclined surface 2042, and the stroke of the first inclined surface 2042 is at least twice the stroke of the second inclined surface 2051, so that the material entering the first inclined surface 2042 has a certain walking path, so that the material discharge channel 205 maintains the material discharge frequency, thereby ensuring that the material does not form congestion in the material discharge area C. In addition, in order to prevent the material from being discharged too quickly, a group of buffer components 21 are provided at the corner where the first inclined surface 2042 and the second inclined surface 2051 are connected, so as to not only prevent the bar material from being crowded at the discharge port 212, but also reduce the design requirements and design costs of the flow channel, and the structure is simple.

[0034] In addition, two protrusions 2041 are provided on the bottom surface of the buffer channel 204, and the two protrusions 2041 are parallel to each other and arranged perpendicular to the conveying direction. The protrusions 2041 form a buffer for the material rolling along the inclined surface, preventing the material rolling from generating acceleration to accidentally open the buffer at the end of the first inclined surface 2042.

[0035] Embodiment 2.

[0036] See also Figure 4 The difference between this embodiment and the first embodiment is that two groups of buffer components 21 are arranged at intervals inside the transfer trough 20 along the conveying direction of the material, and each group of buffer components 211 is a plate-shaped component arranged perpendicular to the conveying direction. A return spring 213 is arranged between the upper end of the buffer component 211 and the rotating shaft 212, and the return spring 213 is sleeved on the rotating shaft 212. By sleeved the return spring 213 on the rotating shaft 212, when the lower end of the buffer component 211 is opened to one side of the conveying direction, the return spring 213 is stressed, and when the material passes through, the buffer component 211 is reset under the action of the release force of the return spring 213, and the next bar material is blocked.

[0037] Embodiment three.

[0038] See also Figure 5The difference between this embodiment and the second embodiment is that the material discharge channel 205 is a zigzag bending structure, and the lower end of the material discharge channel 205 forms a discharge port 202 for a single material to pass through. The zigzag structure lengthens the material discharge channel 205, and at the same time, the material can form a buffer during the falling process, reduce the falling speed, and further prevent the material from being crowded due to too much material entering the material discharge channel. In addition, it can also form a good action docking with the material discharge turntable 3.

[0039] In summary, the utility model provides an anti-congestion transfer mechanism for bar materials, which divides the transfer trough into a plurality of interconnected partitions by arranging a plurality of buffer components at intervals inside the transfer trough; and the upper end of the buffer component is rotatably connected to the transfer trough to achieve connection and closing between the partitions, so that the material can be buffered in each partition to prevent congestion of the material at the feed port and the discharge port, and ensure that the material can be delivered to the trough of the loading turntable one by one in an orderly manner. The structure is simple, easy to maintain, and the mechanism investment cost is low.
