Description

Technical Field

[0001] This utility model relates to the field of screw feeding, specifically a screw quick-reversing feeding device. Background Technology

[0002] In many fields such as machinery manufacturing and electronic assembly, screws are important connecting components, and their feeding efficiency and accuracy directly affect production progress and product quality. Traditional screw feeding devices often suffer from problems such as a single feeding direction, slow reversing speed, and screw jamming during the feeding process.

[0003] Currently, some screw feeding devices on the market require manual adjustment when the feeding direction needs to be changed. This is not only labor-intensive but also cumbersome, severely impacting production efficiency. Even some automatic reversing feeding devices have complex structures and slow reversing response speeds, failing to meet the demands of high-speed production. Furthermore, during the feeding process, screws are prone to jamming in the feed trough, causing feeding interruptions and requiring frequent shutdowns for cleaning, further reducing production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a screw quick-reversing feeding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A screw quick-reversing feeding device includes a storage hopper. Four sets of inclined plates are installed at the center of the inner cavity of the storage hopper. Inclined material channels are slidably connected between the four sets of inclined plates. A horizontal material channel is installed at one end of the inclined material channel. A pusher block is fixedly connected to the end of the horizontal material channel away from the inclined material channel. A lower guide channel is installed on the upper part of the pusher block. An upper cover plate is provided on the upper part of the lower guide channel. A connecting shaft is rotatably connected to the outer wall of the pusher block. An inclined block is installed at the end of the connecting shaft away from the pusher block. A grooved plate is fixedly connected to the top of the inclined block. A contact block is provided at the end of the inclined block away from the grooved plate. A hinge plate is fixedly connected to the bottom of the contact block.

[0007] As a further embodiment of this utility model: one end of the hinge plate two is hinged to the hinge plate one, a cylinder is hinged to the central part of the outer wall of the hinge plate one, and a hinge seat is installed at the end of the cylinder away from the hinge plate one.

[0008] As a further embodiment of this utility model: a base plate is fixedly connected to the end of the hinge seat away from the cylinder, a cylinder seat is fixedly connected to the front end of the outer wall of the connecting shaft, and a push-groove block is telescopically connected to the top of the cylinder seat.

[0009] As a further embodiment of this utility model: the top of the grooved plate is provided with a groove, and the groove opening is in contact with a contact rod. One end of the contact rod is fixedly connected to a guide post, and a transverse groove block is slidably provided on the outer wall of the guide post.

[0010] As a further embodiment of this utility model: a connecting plate is fixedly connected to the end of the transverse groove block away from the contact rod, and an upper cover plate is provided at the bottom of the connecting plate, with the outer wall of the upper cover plate fixedly connected to the connecting plate.

[0011] As a further embodiment of this utility model: a discharge trough block is fixedly connected to the end of the connecting shaft away from the storage hopper; a side groove is provided on the upper side of the discharge trough block; a displacement block is slidably connected to the opening of the side groove; a top plate is installed at the end of the side groove away from the discharge trough block; a push rod is installed at one end of the discharge trough block; and a discharge pipe is installed at the bottom of the discharge trough block, with two sets of discharge pipes.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model uses a cylinder to drive the movement of hinge plate one and hinge plate two, which in turn drives the inclined block and connecting shaft to rotate. The rotation of the connecting shaft causes the discharge trough block and discharge pipe to rotate accordingly, realizing rapid switching of the feeding direction without manual adjustment, greatly improving the reversing efficiency. Its structure is more optimized and its design is more reasonable.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-3 In this embodiment of the invention, a screw quick-reversing feeding device includes a storage hopper 1 for storing screws to be fed. Four sets of inclined plates are installed at the center of the inner cavity of the storage hopper 1. These four sets of inclined plates are distributed at a certain angle, and the channel formed between them is slidably connected to an inclined feed trough 2. Under the action of gravity, the screws are guided into the inclined feed trough 2 by the inclined plates. After entering the storage hopper 1, the screws slide down the inclined feed trough 2 in an orderly manner under the guidance of the four sets of inclined plates. The inclination angle and spacing of the inclined plates are adapted to the screw specifications to prevent blockage.

[0021] Please see Figures 1-3 The inclined material chute 2 is set at an angle, and a horizontal material chute 3 is installed at its lower end. The screw slides from the inclined material chute 2 into the horizontal material chute 3. A push block 26 is fixedly connected to the end of the horizontal material chute 3 away from the inclined material chute 2. The push block 26 performs telescopic movement under the drive of the power device on the top of the cylinder seat 25 to adjust the distance between the upper cover plate 7 and the lower guide chute 8. After the screw enters the horizontal material chute 3, the push block 26 slides along the lower guide chute 8 under the drive of the cylinder 12, pushing the screw from the inclined state to the horizontal direction. The upper cover plate 7 restricts the movement of the top of the screw to ensure the stability of the conveying path.

[0022] Please see Figures 1-3The outer wall of the push block 26 is rotatably connected to a connecting shaft 22 via a bearing. The connecting shaft 22 can rotate around its own axis. An inclined block 21 is installed at the end of the connecting shaft 22 away from the push block 26. A grooved plate 6 is fixedly connected to the top of the inclined block 21. A contact rod 13 contacts the groove of the grooved plate 6. A guide post is fixedly connected to one end of the contact rod 13 and is slidably disposed within the transverse groove block 14. A connecting plate 5 is fixedly connected to the end of the transverse groove block 14 away from the contact rod 13. The connecting plate 5 is fixedly connected to the upper cover plate 7. When the inclined block 21 rotates with the connecting shaft 22, the grooved plate 6 drives the contact rod 13 and the guide post to slide within the transverse groove block 14, pushing... When the groove block 26 moves, the inclined block 21 swings through the connecting shaft 22, and the groove plate 6 rotates accordingly. The contact block 20 pushes the hinge plate 19 and the hinge plate 18 to rotate together, so that the screw completes a 90° turn. The displacement block 16 slides to the target position in the side groove 17. The screw is pushed to the corresponding output pipe 11 by the push rod. The dual-pipe design can supply materials to different workstations at the same time. By adjusting the swing amplitude of the groove plate 6 or the position of the contact rod 13, the screw length changes can be adapted to ensure the stability of the secondary reversal.

[0023] Please see Figures 1-3 A contact block 20 is provided at the end of the inclined block 21 away from the groove plate 6. A hinge plate 29 is fixedly connected to the bottom of the contact block 20. A hinge plate 18 is hinged to one end of the hinge plate 29. A cylinder 12 is hinged to the middle part of the outer wall of the hinge plate 18. A hinge seat 23 is installed at the end of the cylinder 12 away from the hinge plate 18. The hinge seat 23 is fixedly connected to the base plate 24. When the cylinder 12 extends or retracts, it drives the hinge plate 18 and the hinge plate 29 to rotate. The hinge plate 29 pushes the inclined block 21 to rotate through the contact block 20, thereby causing the connecting shaft 22 to rotate.

[0024] Please see Figures 1-3 A discharge trough block 10 is fixedly connected to the end of the connecting shaft 22 away from the storage hopper 1. The rotation of the connecting shaft 22 drives the discharge trough block 10 to rotate, realizing reversal. A side groove 17 is opened on the upper side of the discharge trough block 10. A displacement block 16 is slidably connected in the side groove 17. The displacement block 16 can slide in the side groove 17 to adjust the position of the screw in the discharge trough block 10. A top plate 9 is installed at the end of the side groove 17 away from the discharge trough block 10 to limit the sliding range of the displacement block 16. A push rod is installed at one end of the discharge trough block 10. The push rod pushes the screw to move towards the discharge pipe 11 under the drive of the power device. Two sets of discharge pipes 11 are installed at the bottom of the discharge trough block 10. The corresponding discharge pipe 11 is selected for feeding as needed by rotating the connecting shaft 22.

[0025] During operation, screws are poured into the storage hopper 1, guided by an inclined plate into the inclined trough 2, and then into the horizontal trough 3. Driven by the cylinder seat 25, the pusher block 26 pushes the screws downwards into the channel, between the lower guide trough 8 and the upper cover plate 7. Simultaneously, the cylinder 12 actuates, rotating the connecting shaft 22 to rotate the discharge trough block 10 to the desired feeding direction. After the screws enter the discharge trough block 10, they are pushed out through the corresponding discharge pipe 11 by the push rod, completing the feeding process. When it is necessary to change the feeding direction, simply control the cylinder 12 to rotate the connecting shaft 22, aligning the other set of discharge pipes 11 with the feeding position.

[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
