[0003] In the process of producing fasteners, it is necessary to go through the steps of cutting, annealing, and thread rolling to extend the service life of the fasteners. In the thread rolling process, it is necessary to manually use a small crane to lift the material box to the top of the thread rolling container, and then manually use a ladder or other tools to climb to the top of the thread rolling device (because when the thread rolling equipment is in use, the material needs to slide from a height, because the material needs to be lifted to a suitable height), so that the material box can be tilted to allow the material inside the material box to slide into the container of the thread rolling machine equipment. When pouring materials, most of the material boxes used on the market pour all the materials into the interior of the thread rolling machine container at one time. This will cause the discharge port inside the thread rolling machine to be blocked due to excessive material poured in, making the equipment unable to work for a short time. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figures 1 to 8 , the utility model provides a technical solution:

[0032] A feeding device for fastener production, comprising a mounting bracket 2, on which a first motor 3 is fixedly mounted, on which an output shaft of the first motor 3 is fixedly mounted a screw 31, on which a moving platform 4 is slidably mounted on the circumferential surface of the screw 31, on which a material box 6 is rotatably mounted at the right end of the moving platform 4, on which a second motor 8 is fixedly mounted at both ends of the material box 6, on which a rotating rod 81 is fixedly mounted on the output shaft of the second motor 8, on which a fourth slide groove 82 is provided, an opening and closing plate 7 is slidably mounted at the upper end of the material box 6, on which connecting columns 71 are fixedly mounted at both ends of the opening and closing plate 7, and which extend to the inside of the fourth slide groove 82; a third motor 9 is fixedly mounted at the left end of the material box 6, and cavities are evenly mounted on the output shaft of the third motor 9 Column 10, a pressing column 13 is slidably installed on the cavity column 10; it also includes a movable base 1, a mounting bracket 2 is fixedly installed on the upper end surface of the movable base 1, and a wheel hub 11 is rotatably installed on the lower end surface of the movable base 1; two first slide grooves 21 in a vertical state are opened on the inner side surface of the mounting bracket 2, a tension rod 41 is fixedly installed at the edge of the upper end surface of the movable platform 4, a first slide 42 is fixedly installed on the left end of the tension rod 41, and the first slide 42 is slidably installed inside the first slide groove 21; a cylinder 5 is fixedly installed on the upper end surface of the movable platform 4, and a convex sliding block 62 is rotatably connected to the right end of the telescopic rod of the cylinder 5, a convex sliding block 61 is opened on the left end of the material box 6, and the convex sliding block 62 is slidably installed inside the convex sliding groove 61.

[0033] By adopting the above technical solution, fasteners are a kind of mechanical parts that are used for fastening and connection and are extremely widely used. Various fasteners can be seen in industries including energy, electronics, electrical appliances, machinery, chemicals, metallurgy, molds, hydraulics, etc., and are the most widely used mechanical basic parts; and in the process of producing fasteners, it is necessary to borrow the feeding device many times, so that the semi-finished materials can be raised to a suitable height, so as to pour the semi-finished materials into the conveyor belt or the thread rolling container; during use, the output shaft of the first motor 3 rotates with the screw 31, and when the screw 31 rotates The movable platform 4 can move up and down. During the downward movement of the movable platform 4, the operation process is that the output shaft of the second motor 8 drives the rotating rod 81 to rotate counterclockwise, thereby driving the connecting column 71 to move. The connecting column 71 slides in the third slide groove 64 and the fourth slide groove 82. When the connecting column 71 moves to the left, it can drive the opening and closing plate 7 to move to the left synchronously. After the opening and closing plate 7 moves to the left, it can open the opening at the top of the material box 6. At this time, the worker only needs to pour the semi-finished material into the interior of the material box 6; after the feeding is completed, the opening and closing plate 7 is allowed to complete the sealing of the top opening of the material box 6 according to the above steps.

[0034] The movable base 1 moves to a suitable position with the mounting bracket 2 and the movable platform 4. At this time, the movable platform 4 will move upward and will move synchronously with the material box 6. The material box 6 will stop moving after it moves to a suitable height. The telescopic rod of the cylinder 5 will telescope to the right, allowing the material box 6 to rotate clockwise, and stop rotating after rotating to a suitable angle. When the material box 6 rotates, the convex slider 62 will slide inside the convex slide groove 61, so as to avoid the telescopic rod of the cylinder 5 causing the material box 6 to be unable to rotate to a suitable angle; secondly, the second motor 8 is started, and the output shaft of the second motor 8 drives the rotating rod 81 to rotate in a fan shape, and the rotating rod 81 pushes the connecting column 71 to slide left and right inside the third slide groove 64, so that the opening and closing plate 7 can move back and forth, and the opening and closing plate 7 can open, close and open the opening at the top of the material box 6, and repeat the cycle.

[0035] When the opening of the material box 6 is opened, the output shaft of the third motor 9 can rotate synchronously with the cavity column 10 and the pressing column 13, and when the cavity column 10 and the pressing column 13 rotate, the semi-finished products inside the material box 6 can slide out, and under the restriction of the opening and closing plate 7, the semi-finished products inside the material box 6 will not slide out completely, thereby causing blockage of the thread rolling container mouth, and during use, the first spring 12 is fixedly installed inside the cavity column 10, and the pressing column 13 can make the first spring 12 contract and stretch, so as to avoid the semi-finished material and the pressing column 13 from getting stuck; in addition, two fourth motors 14 are fixedly installed on the top of the interior of the material box 6, and a bottom plate 15 in an inclined state is fixedly installed on the output shaft of the fourth motor 14, and a second spring 16 is fixedly installed on one end face of the bottom plate 15 away from the cavity column 10, and the other end face of the second spring 16 A vibration plate 17 is fixedly installed at the end, and the two ends of the bottom plate 15 and the vibration plate 17 are in contact with the inside of the material box 6 to prevent the material from entering between the bottom plate 15 and the vibration plate 17. The output shaft of the fourth motor 14 drives the bottom plate 15 to rotate in a fan shape, so that the vibration plate 17 can generate pressure on the second spring 16 under the extrusion of the material, so that the second spring 16 can expand and contract and stretch, and under the action of the vibration plate 17, the material can vibrate back and forth to avoid accumulation. During use, semi-finished materials will accumulate on the vibration plate 17, and the vibration plate 17 can make the semi-finished materials vibrate back and forth. In addition, the lower end of the vibration plate 17 can push the material inside the material box 6 to keep the material away from the opening of the material box 6 (the material will slide to the opening of the material box 6 again under the influence of gravity), further preventing the material from accumulating at the opening of the material box 6.

[0036] Specifically, Figures 1 to 8 As shown, two second slide grooves 63 are provided on the inner side of the upper end opening of the material box 6, and third slide grooves 64 are provided on both sides of the upper end of the material box 6, the third slide grooves 64 are connected with the second slide grooves 63, and an opening and closing plate 7 is slidably installed between the two symmetrical second slide grooves 63; a first spring 12 is fixedly installed inside the cavity column 10, and a pressing column 13 is fixedly installed on one end of the outer side of the first spring 12; two fourth motors 14 are fixedly installed on the upper end surface of the interior of the material box 6, and a bottom plate 15 is fixedly installed on the output shaft of the fourth motor 14, four second springs 16 are fixedly installed on the left end surface of the bottom plate 15, and a vibration plate 17 is fixedly installed on the left end of the second spring 16; the bottom plate 15 and the vibration plate 17 are in an inclined state.

[0037] By adopting the above technical solution, when in use, the worker pushes the mobile base 1, and the mobile base 1 moves to a suitable position with the assistance of the wheel hub 11, and the first motor 3 is started. The output shaft of the first motor 3 rotates with the screw 31, and the mobile platform 4 moves upward or downward. When moving downward, the worker loads the material, and moves upward, so that the material box 6 moves to the height of the conveyor belt for annealing or the height of the container box for thread rolling; when the mobile platform 4 moves, it will move synchronously with the tension rod 41. The tension rod 41 slides the first slide 42 inside the first slide 21, and the tension rod 41 generates a pulling force on the mobile platform 4 to avoid the tilting state between the screw 31 and the mobile platform 4 due to the heavy weight of the material box 6, so that the mobile platform 4 cannot slide; under the action of the tension rod 41 and the first slide 42, the screw 31 can drive the mobile platform 4 to slide up and down without getting stuck, and the material box 6 is prevented from tilting due to excessive weight.

[0038] Working principle: First, manually push the mobile base 1, and the mobile base 1 moves to the semi-finished material, and start the second motor 8. The output shaft of the second motor 8 drives the rotating rod 81 to rotate counterclockwise, and the rotating rod 81 drives the connecting column 71 and the opening and closing plate 7 to slide to the left synchronously, and the top opening of the material box 6 is in an open state.

[0039] The materials to be processed in the next step are manually loaded into the material box 6 , and then the above steps are reversed to close the top opening of the material box 6 .

[0040] Then, push the mobile base 1 to move it with the mounting bracket 2, material box 6 and other structures to a suitable position, start the first motor 3, and the output shaft of the first motor 3 moves synchronously with the screw 31. The screw 31 drives the mobile platform 4 to move upward, and the mobile platform 4 moves synchronously with the material box 6, the tension rod 41, and the first slide 42 until it moves to a suitable height.

[0041] Then, the cylinder 5 is started, and the telescopic rod of the cylinder 5 pushes the material box 6 to rotate clockwise, and stops rotating when it rotates to a suitable angle.

[0042] At this time, start the second motor 8, as shown above, and let the opening and closing plate 7 move back and forth left and right, so that the opening of the material box 6 is in an open-closed-open state, so that it can limit the sliding out of the material and prevent too much material from sliding out of the interior of the material box 6 and causing blockage of the thread rolling container.

[0043] Start the third motor 9, and the output shaft of the third motor 9 rotates synchronously with the cavity column 10 and the pressing column 13. Under the action of the cavity column 10 and the pressing column 13, on the one hand, they can prevent the material from sliding out, and on the other hand, when the cavity column 10 and the pressing column 13 rotate, they can slide the material out of the material box 6, which not only solves the problem of material sliding out, but also solves the undesirable situation that the material slides out too fast.

[0044] Finally, the output shaft of the fourth motor 14 drives the base plate 15 and the vibration plate 17 to move synchronously. When the material box 6 is tilted, the material on the vibration plate 17 can fall off due to the vibration of the vibration plate 17. Secondly, the vibration plate 17 can push the material inside the material box 6 away from the cavity column 10 and the pressing column 13, and then move to the cavity column 10 and the pressing column 13 under the action of the tilt angle of the material box 6, further avoiding the situation where the cavity column 10 and the pressing column 13 of the material box are stuck.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
