Description

Technical Field

[0001] This utility model relates to the field of bar feeding equipment, and in particular to a hinged irregular bar feeding machine. Background Technology

[0002] In the processing of hinge parts for aluminum alloy doors and windows, the raw materials are generally first processed into hinge-shaped bars, then the hinge-shaped bars are cut to a fixed length to form hinge-shaped blanks, and finally the hinge-shaped blanks are processed by grinding, drilling, and tapping to finally produce finished hinge parts.

[0003] Traditional bar feeders are similar to the bar feeding device disclosed in ZL202021679492.9, where the pushing device is driven by a servo motor to rotate the conveyor belt between the driving wheel and the driven wheel, and the pushing block on the conveyor belt moves along the guide rod, thereby pushing the bar on the feeding plate. In actual use, the length of the frame of this type of bar feeder limits the distance between the driving wheel and the driven wheel, thus limiting the maximum pushing distance of a single bar.

[0004] Therefore, existing bar feeders have the problem of a short maximum pushing distance. Utility Model Content

[0005] The purpose of this invention is to provide a hinged feeder for irregularly shaped bars. This invention has the advantage of a longer maximum pushing distance.

[0006] The technical solution of this utility model: A hinge-type irregular bar feeder, comprising a frame; a horizontally arranged pusher frame is provided on the frame, and multiple horizontally arranged slide cylinders are connected between the pusher frame and the frame; a horizontally arranged conveyor belt mechanism is connected to the pusher frame, and a connecting block is fixedly connected to the belt body of the conveyor belt mechanism, and a pusher plate located on the longitudinal side of the conveyor belt mechanism is fixedly connected to the connecting block; a guide mechanism for placing hinge-type irregular bars is fixedly connected to the pusher frame at the position corresponding to the pusher plate, and the guide mechanism is horizontally arranged; a sliding cylinder is provided between the conveyor belt mechanism and the guide mechanism. A horizontally arranged push rod has a front fixed platform and a rear fixed platform that are slidably fitted onto its front and rear ends, respectively, and fixed to the push frame. The push rod is slidably set inside a connecting block, and a fork that can swing longitudinally is rotatably connected to its front end. The fork is located between the front fixed platform and the connecting block. One side of the fork has a first slot on the connecting block, and the other side of the fork has a locking block fixed to the front fixed platform. The locking block has a second slot corresponding to the position of the fork. A fixed frame that is fitted onto the push frame is connected to the frame at the position corresponding to the fork. Both sides of the fixed frame are connected to push rods that face the fork and are used to push the fork to swing longitudinally.

[0007] In the aforementioned hinge-type shaped bar feeder, the conveyor belt mechanism includes a drive wheel and a driven wheel rotatably connected to the front and rear ends of the pusher frame, and a belt body fixed to the connecting block is sleeved between the drive wheel and the driven wheel; a drive motor fixed to the pusher frame is connected to the drive wheel for driving the drive wheel to rotate.

[0008] In the aforementioned hinge-type irregular bar feeder, the driving wheel and the driven wheel are located on the outer sides of the front fixed platform and the rear fixed platform, respectively.

[0009] In the aforementioned hinge-type irregular bar feeder, a horizontally arranged slide rail is provided on the pusher frame at the position corresponding to the connecting block; a slide groove is provided on the connecting block at the position corresponding to the slide rail.

[0010] In the aforementioned hinge-type shaped bar feeder, the guiding mechanism includes multiple roller frames that are horizontally spaced apart. Each roller frame is fixedly connected to the pusher frame, and each roller frame is rotatably connected to a vertical track wheel with a concave center.

[0011] In the aforementioned hinge-type irregular bar feeder, one side of the roller frame is provided with a side baffle fixed on the pusher frame in an L-shape.

[0012] In the aforementioned hinge-type shaped bar feeder, a feeding frame is provided on one longitudinal side of the frame, and vertical side plates are connected to both transverse sides of the feeding frame. Multiple evenly spaced No. 1 slots are provided at the top of each side plate, and these No. 1 slots are aligned with each other. A feeding frame is provided on the feeding frame, and multiple vertical telescopic cylinders are connected between the transverse sides of the feeding frame and the feeding frame. Vertically arranged sliders are slidably connected above both transverse sides of the feeding frame, and these sliders are offset relative to the roller frame and side guard frame. Each slider has multiple aligned No. 2 slots, which are aligned with the No. 1 slots and are lower than the No. 1 slots. A connecting rod connects two sliders, and feeding cylinders, arranged horizontally and longitudinally towards the frame, are connected between the two ends of the connecting rod and the feeding frame.

[0013] In the aforementioned hinge-type irregular bar feeder, both sides of the feeding frame are connected to limiting plates located outside the side plates on both sides. The top of the limiting plate is higher than the bottom of the first tray, and both limiting plates are located between the driving wheel and the driven wheel.

[0014] In the aforementioned hinge-type irregular bar feeder, a protective cover is connected to the frame, and a feeding notch is provided on the side of the protective cover facing the feeding frame, and a pushing notch is provided on the protective cover corresponding to the rear end of the frame.

[0015] Compared with the prior art, this utility model has a pusher frame installed on the frame, and multiple horizontally and longitudinally arranged sliding cylinders between the pusher frame and the frame, which allows the pusher frame to move horizontally and longitudinally relative to the frame. When the pusher frame moves horizontally and longitudinally, the push rods on both sides of the fixed frame can push the shift fork, causing the shift fork to swing and switch between the first and second slots. When the shift fork is engaged in the second slot, the conveyor belt mechanism drives the connecting block to move through the belt body, and the connecting block can slide relative to the pusher rod and drive the pusher plate to move horizontally. The conveyor belt moves to the push plate position. When the shift fork is engaged in the first slot, the push rod moves to the push plate position. After the conveyor belt mechanism moves the belt, the connecting block drives the push plate and the shift fork to move laterally in sync. This causes the push rod on the shift fork to move laterally in sync. The push rod can continue to push the hinged shaped bar material pushed out by the push plate. Without increasing the length of the equipment, the maximum pushing distance is greatly increased. This allows a single hinged shaped bar material to be completely pushed into the machine tool even when the frame is outside the machine tool, facilitating subsequent processing operations.

[0016] In addition, in this utility model, the driving wheel and driven wheel of the conveyor belt mechanism are located on the outside of the front fixed platform and the rear fixed platform, respectively, so that the movement range of the belt body driving the connecting block is limited by the front fixed platform and the rear fixed platform, which improves the stability of equipment operation and avoids the risk of equipment damage.

[0017] The groove on the connecting block can slide in conjunction with the horizontal slide rail on the pusher frame, which makes the connecting block more stable when sliding horizontally and pushes the hinged irregular bar stock more stably.

[0018] The guiding mechanism consists of multiple roller frames that are horizontally spaced and fixed on the pusher frame. Each roller frame is rotatably connected to a vertical track wheel with a concave center, which facilitates the placement and pushing of hinge-type shaped bar stock. On one side of each roller frame, there is an L-shaped side baffle fixed on the pusher frame, which can further improve the placement stability of hinge-type shaped bar stock.

[0019] A feeding rack is installed on one longitudinal side of the frame, with vertical side plates connected to both sides. Each side plate has multiple opposing and evenly spaced No. 1 slots, allowing hinged shaped bars to be placed in these slots. The feeding rack is equipped with a lifting feeder, with sliders horizontally and longitudinally connected to both sides. Each slider has multiple opposing No. 2 slots, and a connecting rod connects the two sliders. Feeding cylinders, horizontally oriented towards the frame, connect the two sliders to the feeder at both ends. This allows the No. 2 slots on the sliders to lift the hinged shaped bars in their opposing No. 1 slots after the sliders are raised. The sliders then slide towards the frame and descend, conveying the hinged shaped bars one by one into the frame, making feeding convenient. The two sliders are staggered relative to the roller frame and side guard, allowing the ends of the sliders to extend into the roller frame, thus feeding the hinged shaped bars onto the roller frame.

[0020] Both sides of the feeding rack are connected to limiting plates located outside the sides. The top of the limiting plates is higher than the bottom of the first tray, so that the hinge-type shaped bar stock can be restricted between the two limiting plates. At the same time, both limiting plates are located between the front fixed platform and the rear fixed platform, so that the end of the hinge-type shaped bar stock is not easy to get stuck on the push plate after it is fed, thus ensuring the stability of the equipment operation.

[0021] The protective cover attached to the rack can protect the internal equipment from external influences, and at the same time, the protective cover can prevent workers from coming into contact with moving parts and causing injury.

[0022] Therefore, this invention not only increases the maximum pushing distance, but also has the advantages of high operational stability, convenient feeding, and good protection. Attached Figure Description

Both sides of the fixed frame 15 are connected to push rods 16 that face the fork 11 and are used to push the fork 11 to swing longitudinally.

[0032] The conveyor belt mechanism includes a drive wheel 17 and a driven wheel 18 rotatably connected to the front and rear ends of the pusher frame 2.

[0033] The driving wheel 17 and the driven wheel 18 are located on the outer sides of the front fixed platform 9 and the rear fixed platform 10, respectively.

[0034] The pusher frame 2 is provided with a horizontally arranged slide rail 21 at the position corresponding to the connecting block 4; the connecting block 4 is provided with a slide groove 22 at the position corresponding to the slide rail 21.

[0035] The guiding mechanism includes multiple roller frames 6 that are horizontally spaced apart. Each roller frame 6 is fixedly connected to the pusher frame 2, and each roller frame 6 is rotatably connected to a vertical track wheel 7 with a concave center.

[0036] A side baffle 23, which is fixed to the pusher frame 2 and is arranged in an L-shape, is provided on one side of the roller frame 6.

[0037] A loading rack 24 is provided on one longitudinal side of the frame 1. Vertical side plates 25 are connected to both transverse sides of the loading rack 24. Multiple evenly spaced first slots 26 are provided at the top of each side plate 25. The multiple first slots 26 on the two side plates 25 are aligned with each other. A feeding rack 27 is provided on the loading rack 24. Multiple vertical telescopic cylinders 28 are connected between the transverse sides of the feeding rack 27 and the loading rack 24. Sliding sliders 29 are slidably connected to the upper sides of the transverse sides of the feeding rack 27. The sliders 29 are offset relative to the roller frame 6 and the side baffle 23. Multiple second slots 30 are provided on each slider 29. The second slots 30 are aligned with the first slots 26 and are lower than the first slots 26. A connecting rod 31 is connected between two sliders 29. Feeding cylinders 32 are connected to the two ends of the connecting rod 31 and the feeding rack 27 and are arranged horizontally and longitudinally towards the frame 1.

[0038] Both sides of the feeding rack 24 are connected to limiting plates 36 located outside the side plates 25. The top of the limiting plate 36 is higher than the bottom of the first tray 26. Both limiting plates 36 are located between the driving wheel 17 and the driven wheel 18.

[0039] A protective cover 33 is connected to the frame 1. A feeding notch 34 is provided on the side of the protective cover 33 facing the feeding rack 24, and a pushing notch 35 is provided on the protective cover 33 corresponding to the rear end of the frame 1.

[0040] Working principle: Operators manually or using tools such as cranes place the hinged shaped bar stock onto a pair of No. 1 slots 26 (two opposite No. 1 slots 26 on the two side plates 25 of the feeding rack 24) furthest from the machine frame 1. At this time, both ends of the hinged shaped bar stock are located between the two side limiting plates 36. Subsequently, multiple vertical telescopic cylinders 28 on both sides of the feeding rack 24 drive the feeding rack 27 to lift, and the two sliders 29 on both sides of the feeding rack 27 furthest from the machine frame 1, onto a pair of No. 2 slots 30 (two opposite No. 1 slots 26 on the two side plates 25)... The two opposing No. 2 slots 30 on block 29 (forming a pair) lift and eject the hinged shaped bar material in the pair of No. 1 slots 26 above them; then, the two feeding cylinders 32 on the feeding frame 27 push the two ends of the connecting rod 31 to move towards the machine frame 1, so that the connecting rod 31 drives the two sliders 29 to slide towards the machine frame 1; then the telescopic cylinder 28 shortens and resets, so that the hinged shaped bar material lifted in the No. 2 slot 30 of the two sliders 29 can be placed in the next pair of No. 1 slots 26, realizing the sequential conveying of the hinged shaped bar material towards the machine frame 1. When the hinge-shaped bar stock is conveyed to the pair of slots 26 closest to the frame 1, the feeding rack 27 repeats the above action. The pair of slots 30 closest to the frame 1 on the two sliders 29 can then lift the hinge-shaped bar stock and place it through the feeding notch 34 of the protective cover 33 into the recessed position in the middle of the vertical track wheel 7 on the multiple roller frames 6. The top of the hinge-shaped bar stock can also be lifted by the multiple side baffles 23, so that the hinge-shaped bar stock can be placed stably. Since the limiting plates 36 on both sides of the feeding rack 24 are located between the front fixed platform 9 and the rear fixed platform 10, the end of the hinge-shaped bar stock is not easily stuck on the push plate 5 after feeding.

[0041] When the material is pushed, the fork 11 at the front end of the push rod 8 is engaged in the second slot 14 of the locking block 13; the drive motor 20 on the push frame 2 drives the drive wheel 17 to rotate, causing the belt 19 sleeved on the drive wheel 17 and the driven wheel 18 to rotate; when the belt 19 drives the connecting block 4 to move horizontally, the sliding groove 22 on the connecting block 4 cooperates with the sliding rail 21 on the push frame 2 to slide, which allows the connecting block 4 to move horizontally stably and drive the push plate 5 fixed on the connecting block 4 to move horizontally from the front fixed platform 9 to the rear fixed platform 10. At this time, the push plate 5 can push the hinged shaped bar material placed on multiple vertical track wheels 7.

[0042] After the pusher plate 5 pushes the hinged shaped bar to its maximum distance, the hinged shaped bar is completely pushed out from the pusher notch 35 of the protective cover 33 and is located on the guide frame between the frame 1 and the processing machine tool. Then, the drive motor 20 causes the belt 19 and the connecting block 4 to retract and reset via the drive wheel 17. Next, the slide cylinder 3 drives the pusher frame 2 to move horizontally and longitudinally relative to the frame 1 towards the loading frame 24. The push rod 16 on the fixed frame 15 near the loading frame 24 pushes the shift fork 11 to swing, causing the shift fork 11 to disengage from the second slot 14 and engage in the first slot 12. At the same time, the pusher rod 8 also moves horizontally and longitudinally to the position of the pusher plate 5. Then, the drive motor 20 causes the belt 19 to move via the drive wheel 17, and drives the connecting block 4 and the pusher rod 8, which is engaged with the connecting block 4 by the shift fork 11, to move horizontally and laterally. At this time, the rear end of the pusher rod 8 can extend out of the rear fixed table 10 to continue pushing the hinged shaped bar. The front end of the push rod 8 is in the shape of a regular square prism and is slidably locked in the connecting block 4 and the front fixed platform 9, so that when the connecting block 4 drives the push rod 8 to move, the push rod 8 is not easy to rotate, thus improving the stability of the equipment during operation.

[0043] After the pusher rod 8 pushes the hinge-shaped bar stock, the drive motor 20 resets the belt body 19, connecting block 4 and pusher rod 8 through the drive wheel 17. Then, the slide cylinder 3 drives the pusher frame 2 to reset, and the pusher rod 16 on the side of the fixed frame 15 away from the loading frame 24 pushes the shift fork 11 to swing, so that the shift fork 11 disengages from the first slot 12 and re-enters the second slot 14, waiting to push the next hinge-shaped bar stock.

[0044] The protective cover 33 connected to the rack 1 can protect the internal equipment from external influences, and at the same time, the protective cover 33 can prevent personnel from coming into contact with moving parts and thus causing injury.
