Description

Technical Field

[0001] This utility model relates to the field of screw processing technology, and in particular to a screw processing feeding mechanism. Background Technology

[0002] The screw processing feeding mechanism is an automated auxiliary device specifically designed to automatically, orderly, and accurately transport screw raw materials (such as wire and bar stock) to the processing station of processing equipment (such as punch press, lathe, and thread rolling machine). Its core function is to replace manual feeding and improve the efficiency and precision of screw production.

[0003] Patent CN219708083U discloses a screw processing feeding mechanism, including a base, a flat plate on the base, a collection box on the flat plate, and a feeding component inside the collection box. The feeding component includes a frame, a motor at the bottom of the frame, and rollers at the motor output end. Multiple rollers are located within the frame and are connected by a belt. The belt's outer wall has several equally spaced baffles. A discharge port is located on the upper side wall of the frame, and a discharge channel is located opposite the discharge port. The motor drives the rollers to rotate, and the belt drives the rollers to rotate. The baffles on the belt feed the screws from the collection box to the top, where they are discharged from the discharge port. The screws are then fed along the discharge channel to the drop outlet, thus achieving feeding. This solution has a novel structure, is easy to operate, eliminates the need for manual feeding, saves time and labor, reduces labor costs, facilitates subsequent screw processing, and improves processing efficiency.

[0004] The aforementioned patent has insufficient conveying stability during use. Screws are conveyed upwards by the belt, and when the belt speed is too fast or the screws get slightly stuck in the channel, they will pile up and clog at the discharge port, requiring frequent manual cleaning, which affects the continuity of feeding and increases labor costs. Secondly, it lacks a separating feeding function. The screws are conveyed from the collection box to the discharge port without being separated. Subsequent processing stations may need additional sorting equipment or processes to pick up and process individual screws. Based on this, a screw processing feeding mechanism is proposed for improvement. Utility Model Content

[0005] In view of the problems of insufficient conveying stability, easy stacking and congestion at the discharge port, and lack of separation feeding function of the existing device, this utility model is proposed.

[0006] To solve the above technical problems, the present invention provides the following technical solution: a screw processing feeding mechanism, including a workbench, characterized in that: a material box is fixedly installed at one end of the top of the workbench, and the workbench is provided with a feeding mechanism for feeding materials, a conveying mechanism for conveying screws, and a separating feeding mechanism for separating screws;

[0007] A first motor is fixedly installed on one side of the material box. The output shaft of the first motor is connected to a rotating rod through a first sprocket transmission assembly. The rotating rod is rotatably connected to the inner wall of the material box. A rotating wheel is fixedly sleeved on the middle surface of the material box. Several material grooves are opened on the surface of the rotating wheel.

[0008] A connecting plate is fixedly connected to one side of the material box. One end of the connecting plate is fixedly connected to the side wall of the material box. An I-beam is provided at the top of the connecting plate. One end of the I-beam extends into the inside of the material box. Belt conveyor assemblies are rotatably connected to both sides of the I-beam. The pulleys of the two belt conveyor assemblies are connected by synchronous shaft transmission. Extension belts are fixedly connected to the inner sides of the belts of the two belt conveyor assemblies. The extension belts are slidably connected to the surface of the I-beam. A transmission rod is connected to one end of the rotating rod through a second sprocket transmission assembly. One end of the transmission rod passes through the side wall of the material box and is connected to the pulley of one belt conveyor assembly.

[0009] As a preferred embodiment, the I-beam frame is fixedly connected to two support plates on both sides of its middle section, and the support plates are fixedly connected to the top of the connecting plate.

[0010] As a preferred embodiment, a pressure plate is fixedly connected to the top of the connecting plate, the pressure plate is located above the I-beam frame, one end of the pressure plate is fixedly connected to the upper part of the material box's outer wall discharge port, and guide plates are symmetrically arranged above the material box's inner wall discharge port.

[0011] As a preferred embodiment, a mounting frame is fixedly installed at the other end of the top of the workbench. The top of the mounting frame is symmetrically provided with arc-shaped plates. A second motor is provided below the mounting frame. The output shaft of the second motor is fixedly sleeved with a rotating shaft. A gear is fixedly sleeved on the surface of the rotating shaft. A gear plate is meshed on the surface of the gear. A rotating column is fixedly sleeved inside the gear plate. The top of the rotating column passes through the bottom end of the mounting frame and is fixedly sleeved with a turntable. The turntable is rotatably connected between the two arc-shaped plates. Several material holes are opened on the circumference of the side of the turntable.

[0012] As a preferred embodiment, the other end of the I-beam extends to the inlet of the two arc-shaped plates, and the outlet of the two arc-shaped plates is provided with a discharge pipe, the inclined end of which is fixedly connected to one end of the workbench.

[0013] As a preferred embodiment, a push rod is fixedly connected to the top of one side of the arc-shaped plate, and the push rod is inclined.

[0014] As a preferred embodiment, the push rod is disposed at the outlet of the two arc-shaped plates, and the bottom end of the push rod contacts the top end of the turntable.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects:

[0016] 1. This utility model relies solely on the first motor for power, drives the rotating wheel to feed material through the first sprocket transmission assembly, and simultaneously drives the belt conveyor assembly 43 to transport material through the second sprocket transmission assembly. This eliminates jamming, improves overall feeding efficiency, and reduces labor costs. Furthermore, the material trough provides quantitative material guidance, the guide plate accurately drops material, and the extension belt clamps and pressure plate limits the screws, ensuring vertical conveying without deviation.

[0017] 2. This utility model, through the cooperation of the feeding mechanism and the separating feeding mechanism, enables the material holes on the side circumference of the turntable to achieve physical separation of one screw per hole, avoiding the channel blockage problem caused by the stacking and squeezing of multiple screws in traditional feeding, reducing the frequency of machine downtime for cleaning, and the separated screws are continuously output as single screws through the discharge pipe. Subsequent processing stations need to sort them separately, and screws can be directly grabbed according to a fixed rhythm, avoiding processing wait or missed processing due to unstable feeding volume, and improving the rhythm matching of the entire production line.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Reference Figures 1-5 This is the first embodiment of the present utility model, which provides a screw processing feeding mechanism, including a workbench 1, a material box 2 fixedly installed at one end of the top of the workbench 1, a feeding mechanism 3 for feeding materials, a conveying mechanism 4 for conveying screws, and a separating feeding mechanism 5 for separating screws.

[0027] A first motor 31 is fixedly installed on one side of the material box 2. The output shaft of the first motor 31 is connected to a rotating rod 33 through a first sprocket transmission assembly 32. The rotating rod 33 is rotatably connected to the inner wall of the material box 2. A rotating wheel 34 is fixedly sleeved on the middle surface of the material box 2. Several material grooves 35 are opened on the surface of the rotating wheel 34.

[0028] A connecting plate 41 is fixedly connected to one side of the material box 2. One end of the connecting plate 41 is fixedly connected to the side wall of the material box 2. An I-beam frame 42 is provided at the top of the connecting plate 41. One end of the I-beam frame 42 extends into the inside of the material box 2. Belt conveyor assemblies 43 are rotatably connected to both sides of the I-beam frame 42. The pulleys of the two belt conveyor assemblies 43 are connected by a synchronous shaft 44. Extension belts 45 are fixedly connected to the inner side of the belts of the two belt conveyor assemblies 43. The extension belts 45 are slidably connected to the surface of the I-beam frame 42. A transmission rod 47 is connected to one end of the rotating rod 33 by a second sprocket transmission assembly 46. One end of the transmission rod 47 passes through the side wall of the material box 2 and is connected to the pulley of one side of the belt conveyor assembly 43.

[0029] Support plates 421 are fixedly connected to both sides of the middle part of the I-beam 42, and the support plates 421 are fixedly connected to the top of the connecting plate 41;

[0030] A pressure plate 48 is fixedly connected to the top of the connecting plate 41. The pressure plate 48 is located above the I-beam frame 42. One end of the pressure plate 48 is fixedly connected to the upper part of the material box 2's outer wall discharge port. Guide plates 49 are symmetrically arranged above the material box 2's inner wall discharge port.

[0031] Specifically, the first motor 31 is started, and its output shaft drives the rotating rod 33 to rotate through the first sprocket transmission assembly 32. The rotating rod 33 drives the rotating wheel 34 to rotate. When the rotating wheel 34 rotates, the screws piled in the material box 2 will fall into the material trough 35. As the rotating wheel 34 continues to rotate, when the material trough 35 with screws rotates to the material box 2 outlet position, the screws will be released from the material trough 35 under the action of gravity. The screws are guided by the guide plate 49 to fall accurately between the two belt conveyor assemblies 43, and the screws are vertically stuck on the extension belt 45 on the opposite side of the belts of the two belt conveyor assemblies 43.

[0032] Simultaneously with the rotation of rod 33, the rotation of rod 33 drives the rotation of transmission rod 47 through the second sprocket transmission assembly 46. Transmission rod 47 directly drives the pulley of belt conveyor assembly 43 on one side of I-beam frame 42 to rotate. This pulley, in turn, drives the pulley of belt conveyor assembly 43 on the other side of I-beam frame 42 to rotate synchronously through synchronous shaft 44, so that the belts on both sides move at the same speed. The extension belt 45 on the inner side of the belts on both sides slides against the surface of I-beam frame 42, and the screw is stably conveyed along the direction of I-beam frame 42 through friction. During the stable conveying of the screw along the direction of I-beam frame 42, the pressure plate 48 will limit the screw to prevent the screw from tilting or deviating due to inertia during the conveying process.

[0033] This design relies solely on the first motor 31 for power, driving the rotating wheel 34 to feed material via the first sprocket transmission assembly 32. Simultaneously, the second sprocket transmission assembly 46 drives the belt conveyor assembly 43 to transport material, eliminating jamming and improving overall feeding efficiency. Furthermore, the material trough 35 provides quantitative material guidance, and the guide plate 49 accurately drops the material. Combined with the clamping of the extension belt 45 and the limiting of the pressure plate 48, this ensures that the screws are transported vertically without deviation, meeting the strict requirements of the processing end for the screw posture, reducing the risk of deviation during screw transportation, and simplifying operation and maintenance.

[0034] Reference Figures 1-5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a mounting frame 51 is fixedly installed at the other end of the top of the workbench 1. The top of the mounting frame 51 is symmetrically provided with arc-shaped plates 52. A second motor 53 is provided below the mounting frame 51. The output shaft of the second motor 53 is fixedly sleeved with a rotating shaft 54. A gear 55 is fixedly sleeved on the surface of the rotating shaft 54. A gear disk 56 is meshed on the surface of the gear 55. A rotating column 57 is fixedly sleeved inside the gear disk 56. The top of the rotating column 57 passes through the bottom end of the mounting frame 51 and is fixedly sleeved with a turntable 58. The turntable 58 is rotatably connected between the two arc-shaped plates 52. Several material holes 59 are opened on the circumference of the side of the turntable 58.

[0035] The other end of the I-beam 42 extends to the inlet of the two arc-shaped plates 52, and the outlet of the two arc-shaped plates 52 is provided with a discharge pipe 6. The inclined end of the discharge pipe 6 is fixedly connected to one end of the workbench 1.

[0036] A push rod 510 is fixedly connected to the top of one side of the arc plate 52, and the push rod 510 is set at an angle.

[0037] The push rod 510 is located at the outlet of the two arc plates 52, and the bottom end of the push rod 510 contacts the top end of the turntable 58.

[0038] Specifically, when the screws are conveyed to the inlets of the two arc-shaped plates 52 via the I-beam frame 42, the second motor 53 is started. Its output shaft drives the rotating shaft 54 ​​to rotate, which in turn drives the gear 55 to rotate. The gear 55 drives the rotating column 57 to rotate synchronously via the gear plate 56, which in turn drives the turntable 58 to rotate synchronously between the two arc-shaped plates 52. The material holes 59 on the side circumference of the turntable 58 rotate accordingly. When the material holes 59 rotate to the inlet of the arc-shaped plate 52, they receive the screws from the conveying mechanism 4. Each material hole 59 can only hold one screw. Then the turntable 58 continues to rotate, rotating the material holes 59 with screws to the outlet of the arc-shaped plate 52, thereby separating the continuous screws one by one.

[0039] When the screw-loaded material hole 59 reaches the outlet of the arc plate 52, the bottom end of the push rod 510 at the top of the arc plate 52 contacts the top of the turntable 58, which will push the screw out of the material hole 59. The screw falls into the discharge pipe 6 below and slides through the inclined discharge pipe 6 to the subsequent processing station to complete the entire feeding process.

[0040] This design, through the cooperation of the feeding mechanism 4 and the separating feeding mechanism 5, enables the material holes 59 on the side circumference of the turntable 58 to achieve physical separation of one screw per hole. This avoids the channel blockage problem caused by the stacking and squeezing of multiple screws in traditional feeding, reducing the frequency of machine downtime for cleaning. The separated screws are continuously output as single screws through the discharge pipe 6. Subsequent processing stations need to sort them separately. Screws can be directly grabbed at a fixed rhythm, avoiding processing wait or missed processing due to unstable feeding volume, and improving the rhythm matching of the entire production line.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
