[0002] ‌The feeding device is used to send the oriented workpieces to the processing position. It is a device in industrial production for automatically or semi-automatically transporting raw materials or parts from the storage position to the production line or processing equipment. The bar feeding device is to install a bar of a certain length in the feeding pipe. After each workpiece is processed by the machine tool, the feeding mechanism automatically feeds the bar into the spindle hole of the machine tool according to the required length once, and is generally used for automatic lathes.

[0003] The utility model with the publication number CN205204251U discloses an automatic feeding mechanism for a roller raw material bin, including a roller raw material and a bin frame body, adopting a V-shaped structure. The upper part of the V-shaped structure stores the roller raw material. The V-shaped structure includes a fixed side of the V-shaped structure and a swinging side of the V-shaped structure; one end of the fixed side of the V-shaped structure is fixedly connected to the upper end of one side of the bin frame body, and the other end of the fixed side of the V-shaped structure is fixedly connected to the inner bottom of the bin frame body; one end of the swinging side of the V-shaped structure is hinged to the upper end of the other side of the bin frame body, and the other end of the swinging side of the V-shaped structure intersects with the fixed side of the V-shaped structure at an obtuse angle.

[0004] In the feeding mechanism of the above technical solution, during feeding, due to the accumulation of the rods, it is easy for multiple rod materials in the bin to fall into the next link simultaneously during feeding, which affects the stability of feeding. Summary of the Utility Model

[0005] In order to make the feeding of long rod-shaped parts more stable and efficient, the present application provides an automatic and efficient feeding mechanism for long rod-shaped raw materials of sewing machine accessories.

[0006] The automatic and efficient feeding mechanism for long rod-shaped raw materials of sewing machine accessories provided by the present application adopts the following technical solutions:

[0007] An automatic and efficient feeding mechanism for long rod-shaped raw materials of sewing machine accessories, including a main frame and a feeding assembly. A placing rod and a pushing plate for placing raw materials are provided on the main frame. One end of the placing rod abuts against the pushing plate. A limiting block is provided on the placing rod. The feeding assembly is used to convey the raw materials on the placing rod to the pushing plate. The feeding assembly includes a movable rod and a driving member. The movable rod is rotatably connected to the main frame. An abutting block is provided on the movable rod. The raw material is located on the rotation path of the abutting block. The driving member is used to drive the rotation of the movable rod. When the movable rod rotates towards the limiting block side to the extreme position, the top surface of the abutting block is flush with the top surface of the limiting block.

[0008] By adopting the above technical solution, the limit block limits the movement of the raw material on the placing rod. When the raw material abuts against the limit block, the movable rod is driven to rotate through the driving member. During the rotation of the movable rod, the raw material abutting against the limit block is driven to move along the side wall of the limit block. When the movable rod rotates toward the limit block to the extreme position, the raw material slides along the top surface of the limit block to the pushing plate, completing the loading of the raw material, making the loading of long rod-shaped parts more stable and efficient.

[0009] Preferably, the placement rod gradually becomes closer to the bottom surface of the main frame from one end close to the push plate to one end far away from the push plate.

[0010] By adopting the above technical solution, when the raw material is placed on the rod, it can slide by gravity until it abuts against the side of the limiting block.

[0011] Preferably, the driving member includes a spring and a cam, the cam is connected to the main frame and rotates along the rotation direction of the movable rod, the circumferential side of the cam abuts against the movable rod, and the spring is arranged on the movable rod, and the spring always drives the movable rod to slide toward the side away from the limit block.

[0012] By adopting the above technical solution, the cam is rotated. When one end of the cam protrusion abuts against the movable rod, the movable rod rotates toward the side of the limit block. At this time, the spring is deformed. When the protruding end of the cam leaves the movable rod, the spring is reset, driving the movable rod to slide toward the side away from the limit block, thereby reducing the possibility of the movable rod getting stuck and making the loading of long rod-shaped parts more stable and efficient.

[0013] Preferably, a partition block is provided on the abutment block, and the partition block is arranged in a tapered shape from one end close to the abutment block to one end away from the abutment block. When the movable rod rotates toward the limit block to the extreme position, the partition block is located between two adjacent raw materials.

[0014] By adopting the above technical solution, two adjacent raw materials are separated by a dividing block, thereby reducing the possibility that the abutment block simultaneously drives the two raw materials to move. The dividing block also plays a limiting role, thereby reducing the possibility that the raw materials roll toward the side away from the push plate and separate from the abutment block during the process of the abutment block driving the raw materials to move, thereby making the loading of long rod-shaped parts more stable and efficient.

[0015] Preferably, an adjusting member is further included, wherein the limiting block is slidably connected to the placing rod along the length direction of the placing rod, and the adjusting member is used to drive the sliding of the limiting block.

[0016] By adopting the above technical solution, the position of the limit block on the placement rod is adjusted by the adjusting member, so that the feeding mechanism can adapt to rods with more diameters.

[0017] Preferably, the adjusting member includes a rack and a gear. The rack is fixedly connected to the limiting block, and the gear is rotatably connected to the placing rod. The gear is meshed with the rack.

[0018] By adopting the above technical solution, rotating the gear drives the rack to slide through the meshing connection between the gear and the rack, thereby adjusting the position of the limiting block on the placing rod.

[0019] Preferably, a limiting plate is slidably connected to the main frame, and the limiting plate and the placing rod are respectively located on both sides of the raw material in the circumferential direction.

[0020] By adopting the above technical solution, the raw material is limited by the limiting plate, reducing the possibility of raw material stacking and the possibility of driving multiple raw materials into the pushing groove simultaneously, making the feeding of the long rod-shaped parts more stable and efficient; at the same time, the limiting plate is slidably connected, facilitating the adjustment of the position of the limiting plate on the main frame, so that the feeding mechanism can be applied to rod-shaped raw materials of more sizes.

[0021] The technical effects of the present utility model are mainly reflected in the following aspects:

[0022] 1. By setting the feeding assembly in the present utility model, the movement of the raw material is restricted by the limiting block. When the raw material abuts against the limiting block, the driving member drives the rotation of the movable rod. During the rotation of the movable rod, the raw material abutting against the limiting block is driven to move. When the movable rod rotates towards the limiting block to the extreme position, the raw material slides along the top surface of the limiting block onto the pushing plate, completing the feeding of the raw material, making the feeding of the long rod-shaped parts more stable and efficient;

[0023] 2. By setting the partition block in the present utility model, the adjacent two raw materials are separated by the partition block, reducing the possibility of the abutting block driving two raw materials to move simultaneously, and the partition block also plays a role in limiting, reducing the possibility that the raw material rolls away from the abutting block towards the side away from the pushing plate during the process of the abutting block driving the raw material to move, making the feeding of the long rod-shaped parts more stable and efficient;

[0024] 3. By setting the limiting plate in the present utility model, the raw material is limited by the limiting plate, reducing the possibility of raw material stacking and the possibility of driving multiple raw materials into the pushing groove simultaneously, making the feeding of the long rod-shaped parts more stable and efficient; at the same time, the limiting plate is slidably connected, facilitating the adjustment of the position of the limiting plate on the main frame, so that the feeding mechanism can be applied to rod-shaped raw materials of more sizes.

Detailed implementation manners

[0031] The following further elaborates on the present application in conjunction with the attached Figures 1-5 to make the technical solution of the present application easier to understand and master.

[0032] The embodiment of the present application discloses an automatic and efficient feeding mechanism for long rod-shaped raw materials of sewing machine accessories.

[0033] Referring to Figures 1-5 , an automatic and efficient feeding mechanism for long rod-shaped raw materials of sewing machine accessories in this embodiment includes a main frame 1 and several groups of feeding assemblies 2. A plurality of placing rods 11 for placing raw materials and a pushing plate 13 are fixedly connected to the main frame 1. The plurality of placing rods 11 are evenly distributed along the length direction of the main frame 1. One end of the plurality of placing rods 11 in the length direction abuts against the pushing plate 13. Limiting blocks 111 are slidably connected to the plurality of placing rods 11 along the length direction of the placing rods 11. The distance from one end of the plurality of placing rods 11 close to the pushing plate 13 to the end far from the pushing plate 13 gradually approaches the bottom surface of the main frame 1. The several groups of feeding assemblies 2 respectively correspond to the several placing rods 11.

[0034] Referring to Figures 1-5 , the feeding assembly 2 is used to convey the raw materials on the placing rod 11 to the pushing plate 13. Taking a single group of feeding assemblies 2 as an example, the feeding assembly 2 includes a movable rod 21 and a driving member 22. The movable rod 21 is rotatably connected to the placing rod 11 along the length direction of the main frame 1. An abutting block 211 is fixedly connected to the movable rod 21. The raw materials abutting against the limiting block 111 are located on the rotation path of the abutting block 211. The driving member 22 is used to drive the rotation of the movable rod 21. When the movable rod 21 rotates towards the limiting block 111 to the extreme position, the top surface of the abutting block 211 is flush with the top surface of the limiting block 111.

[0035] Reference Figures 1-5 The driving member 22 includes a spring 221 and a cam 222. The cam 222 is connected to the main frame 1 in a rotational direction of the movable rod 21. The circumferential side of the cam 222 abuts against the bottom surface of the movable rod 21. The two ends of the spring 221 are respectively fixedly connected to the movable rod 21 and the main frame 1. The spring 221 always drives the movable rod 21 to slide toward the side away from the limit block 111.

[0036] Reference Figures 1-5 A driving rod 223 is connected to the main frame 1 so as to rotate along the rotation direction of the cam 222. The driving rod 223 is coaxially and fixedly connected to a plurality of cams 222. A driving motor is installed on the main frame 1 to drive the driving rod 223 to rotate, so that the movable rods 21 on the multiple groups of feeding components 2 move synchronously.

[0037] Reference Figures 1-5 When the raw material is placed on the rod 11 , it slides by gravity until it abuts against the side of the limit block 111 , and the limit block 111 limits the movement of the raw material on the rod 11 . When the raw material abuts against the limit block 111, the movable rod 21 is driven to rotate by the driving member 22, that is, the cam 222 is rotated by the driving rod 223. When one end of the cam 222 abuts against the movable rod 21, the movable rod 21 rotates toward the side of the limit block 111. At this time, the spring 221 is deformed. When the raised end of the cam 222 leaves the movable rod 21, the spring 221 is reset, driving the movable rod 21 to slide toward the side away from the limit block 111, reducing the possibility of the movable rod 21 being stuck. During the rotation of the movable rod 21, the raw material abutting against the limit block 111 is driven to move along the side wall of the limit block 111. When the movable rod 21 rotates to the limit position toward the side of the limit block 111, the raw material slides along the top surface of the limit block 111 to the push plate 13, completing the loading of the raw material, making the loading of long rod-shaped parts more stable and efficient.

[0038] Reference Figure 3 A partition block 212 is fixedly connected to the top surface of the end of the abutment block 211 away from the push plate 13. The partition block 212 is arranged in a tapered shape from the end close to the abutment block 211 to the end away from the abutment block 211. When the movable rod 21 rotates to the limit position toward the limit block 111, the partition block 212 is located between two adjacent raw materials. The two adjacent raw materials are separated by the partition block 212, which reduces the possibility that the abutment block 211 drives the two raw materials to move at the same time. The partition block 212 also plays a role of limiting, which reduces the possibility that the raw materials roll toward the side away from the push plate 13 and separate from the abutment block 211 during the process of the abutment block 211 driving the raw materials to move, so that the loading of long rod-shaped parts is more stable and efficient.

[0039] Reference Figure 4 and Figure 5, the adjusting member 12 is used to drive the sliding of the limiting block 111. By adjusting the position of the limiting block 111 on the placing rod 11 through the adjusting member 12, the feeding mechanism can adapt to rod-shaped workpieces with more diameters. The adjusting member 12 includes a rack 121 and a gear 122. The rack 121 is fixedly connected to the limiting block 111, and the gear 122 is rotatably connected to the placing rod 11. The gear 122 is meshed with the rack 121. The main frame 1 is rotatably connected with a force-applying rod 123 along the rotation direction of the gear 122, and the force-applying rod 123 is coaxially and fixedly connected to a plurality of gears 122. Applying force to the force-applying rod 123 causes the plurality of gears 122 to rotate simultaneously. Through the meshing connection between the gear 122 and the rack 121, the rack 121 is driven to slide, thereby adjusting the position of the limiting block 111 on the placing rod 11; by simultaneously driving the rotation of the plurality of gears 122 through the force-applying rod 123, the gears 122 in multiple sets of adjusting members 12 can rotate synchronously, making the feeding of long rod-shaped parts more stable and efficient.

[0040] Refer to Figures 1-5 , a limiting plate 14 is slidably connected to the main frame 1 along the length direction perpendicular to the placing rod 11. The limiting plate 14 and the placing rod 11 are respectively located on both sides of the circumference of the raw material. A plurality of sliding grooves 141 are formed in the limiting plate 14. A plurality of bolts 142 are threadedly connected to the main frame 1. The plurality of bolts 142 respectively correspond to the plurality of sliding grooves 141. One ends of the plurality of bolts 142 respectively penetrate through the corresponding sliding grooves 141 and are slidably connected in the sliding grooves 141. When the plurality of bolts 142 are rotated until they abut against the limiting plate 14, the movement of the limiting plate 14 is limited. After loosening the plurality of bolts 142, the limiting plate 14 is slid to adjust the distance between the limiting plate 14 and the placing rod 11.

[0041] Refer to Figures 1-5 , the raw material is limited by the limiting plate 14, reducing the possibility of raw material stacking and the possibility of driving multiple raw materials into the pushing plate 13 simultaneously, making the feeding of long rod-shaped parts more stable and efficient; at the same time, the limiting plate 14 is slidably connected, facilitating the adjustment of the position of the limiting plate 14 on the main frame 1, so that the feeding mechanism can be applied to rod-shaped raw materials of more sizes.

[0042] Of course, the above are only typical examples of the present application. In addition, the present application can also have many other specific implementation manners. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present application.
