Description

Technical Field

[0001] This utility model relates to the field of screw machine feeding technology, specifically a vibratory feeding device for screw machines to prevent jamming. Background Technology

[0002] In modern industrial production, screw tightening machines, as key automated equipment, play a vital role in the assembly of various products. They can quickly and accurately tighten screws, significantly improving production efficiency and product quality stability. The vibratory feeding device, as the core component of the screw tightening machine, is responsible for orderly and stablely conveying screws to the designated position to ensure the smooth progress of subsequent tightening processes.

[0003] Traditional screw-feeding machines typically use a simple tray paired with a vibrating motor to transport screws. In practical applications, this traditional structure has significant drawbacks due to design limitations. When conveying screws, the lack of an effective guiding and adjusting mechanism makes them prone to jamming in the tray, causing poor conveying or even interruption of supply, severely impacting the screw-feeding machine's operating rhythm and reducing production efficiency. Furthermore, traditional devices struggle to flexibly adjust the size of the feed opening according to the dimensions and shapes of screws of different specifications, limiting the applicable range of the screw-feeding machine. Therefore, a screw-feeding machine anti-jamming vibrating feeding device is proposed. Utility Model Content

[0006] (II) Technical Solution

[0007] To achieve the aforementioned goals of flexibly adjusting the size of the feed inlet and the tilt angle of the feed tray, this utility model provides the following technical solution:

[0008] A vibratory feeding device for screw making machine to prevent jamming includes a material tray for placing screws, the tail of the material tray is provided with two sets of guide components and adjustment components, and the bottom surface is provided with a vibratory motor.

The other end of the third guide plate is hinged to the side baffle of the material tray. The first guide plate, the second guide plate, and the third guide plate all slide on the material tray.

[0010] The adjustment assembly includes a housing fixed on the material tray, and a screw with positive and negative threads is rotatably connected inside the housing. Two sleeves with opposite thread directions are threaded onto the screw. A clamping plate is provided on the left and right sides of each sleeve. The clamping plate is hinged to the sleeve on the same side via a connecting rod.

[0011] The clamping plate is fixedly connected to the first guide plate.

[0012] A preferred embodiment of this invention is that the portion of the screw with positive and negative threads located on the outer side of the housing is provided with an adjustment handle, and the axis of the screw with positive and negative threads is parallel to the central axis of the feed tray.

[0013] A preferred embodiment of this invention is that each of the clamps is further provided with at least two circular rods penetrating the shell.

[0014] A preferred embodiment of this invention is that a rotating shaft is provided on the bottom surface of the tail end of the material tray, and the material tray is rotatably connected to a base plate via the rotating shaft.

[0015] A preferred embodiment of this utility model is that an inclined component is provided on the side of the base plate away from the rotating shaft between the base plate and the material tray.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides a vibratory feeding device for screw making machines to prevent jamming, which has the following advantages:

[0019] This screw machine uses a vibratory feeding device to prevent jamming. By adjusting the rotation of the positive and negative thread screws in the adjustment assembly, the rod sleeve and clamping plate are moved, thereby flexibly adjusting the position of the first guide plate and realizing flexible adjustment of the feeding port size.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] Please see Figure 1-6 A vibratory feeding device for screw making machine to prevent jamming includes a feed tray 1 for placing screws. The feed tray 1 has two sets of guide components 5 and an adjusting component 6 at its tail, and a vibratory motor 4 on its bottom surface. The guide components 5 include a first guide plate 501, a second guide plate 502, and a third guide plate 503 that are hinged in sequence. The other end of the third guide plate 503 is hinged to a side baffle of the feed tray 1. The first guide plate 501, the second guide plate 502, and the third guide plate 503 all slide on the feed tray 1. The adjusting component 6 includes a housing 601 fixed to the feed tray 1. A screw 602 with positive and negative threads is rotatably connected inside the housing 601. Two sleeves 603 with opposite thread directions are threaded onto the screw 602. A clamping plate 605 is provided on the left and right sides of each sleeve 603. The clamping plate 605 is hinged to the same side of the sleeve 603 via a connecting rod 604. The clamping plate 605 is fixedly connected to the first guide plate 501.

[0032] In this embodiment, the portion of the screw 602 located outside the housing 601 is provided with an adjustment handle 607, and the axis of the screw 602 is parallel to the central axis of the tray 1.

[0033] It should be noted that the adjustment handle 607 greatly facilitates the operator's rotation of the threaded screw 602. In actual production scenarios, the operator does not need to use complex tools; simply rotating the adjustment handle 607 manually is sufficient to easily rotate the threaded screw 602. The design that the axis of the threaded screw 602 is parallel to the central axis of the material tray 1 ensures that the movement direction of the sleeve 603 matches the relevant layout of the material tray 1 when the screw 602 rotates. This allows for precise adjustment of the position of the first guide plate 501, thereby stably adjusting the size of the feed opening.

[0034] In this embodiment, each clamping plate 605 is also provided with at least two round rods 606 that penetrate the housing 601.

[0035] It should be noted that the round rod 606, which penetrates the housing 601, plays an important guiding and limiting role. During the operation of the adjusting component 6, when the positive and negative threaded screws 602 rotate, driving the sleeve 603 and the clamping plate 605 to move, the round rod 606 can ensure that the clamping plate 605 moves stably along a specific straight direction, preventing the clamping plate 605 from deviating or shaking during the movement. This ensures that the position adjustment of the first guide plate 501 is accurate, making the adjustment of the feed opening size more reliable and improving the stability and adjustment accuracy of the entire device.

[0036] In this embodiment, a rotating shaft 101 is also provided on the bottom surface of the tail of the material tray 1, and the material tray 1 is rotatably connected to the base plate 2 through the rotating shaft 101.

[0037] It should be noted that the design of the rotating shaft 101 provides the basis for the relative rotation between the material tray 1 and the base plate 2. Through the connection of the rotating shaft 101, the material tray 1 can rotate around the shaft 101 at a certain angle, which creates conditions for subsequent adjustment of the tilt angle of the material tray 1. This rotating connection method is simple and reliable in structure, capable of withstanding various forces generated by the material tray 1 during vibration and rotation, ensuring the stable connection between the material tray 1 and the base plate 2, and providing support for the normal operation of the entire device.

[0038] In this embodiment, an inclined component 3 is also provided on the side of the base plate 2 away from the rotating shaft 101 between the base plate 2 and the material tray 1. The inclined component 3 includes a slider 301 that slides on the bottom of the material tray 1, a fixing block 302 that is fixed to the top of the base plate 2, and an electric push rod 303. The two ends of the electric push rod 303 are respectively hinged to the slider 301 and the fixing block 302.

[0039] It should be noted that the tilting component 3 is the key part for adjusting the tilt angle of the tray 1. The electric push rod 303 serves as the power source, and its extension and retraction movement drives the slider 301 to slide at the bottom of the tray 1. Since the slider 301 is slidably connected to the bottom of the tray 1, and the other end of the electric push rod 303 is hinged to the fixing block 302 fixed to the base plate 2, when the electric push rod 303 extends or retracts, it pushes or pulls the tray 1 to rotate around the rotating shaft 101, thereby adjusting the tilt angle of the tray 1. This design makes the adjustment of the tray 1's tilt angle more automated and precise, enabling quick and accurate adjustment of the tray 1's angle according to actual production needs, thus improving production efficiency.

[0040] It should be further noted that the hinge joints between the electric push rod 303 and the slider 301 and the fixed block 302 are all equipped with buffer and shock absorption structures to improve the service life of the device.

[0041] In this embodiment, the clamping plate 605 and the first guide plate 501 are connected by threaded fasteners; the threaded fasteners pass through the clamping plate 605 and are screwed into the threaded holes of the first guide plate 501, so that the clamping plate 605 and the first guide plate 501 are rigidly fixed.

[0042] It should be noted that the use of threaded fasteners to connect the clamping plate 605 and the first guide plate 501 offers advantages such as a secure connection and easy disassembly. During device assembly, the clamping plate 605 and the first guide plate 501 can be quickly and accurately fixed together, ensuring stable relative positions between them and guaranteeing that the adjusting component 6 can effectively move the first guide plate 501. Furthermore, when maintenance or component replacement is required, simply unscrewing the threaded fasteners allows for easy separation of the clamping plate 605 from the first guide plate 501, facilitating repair and replacement and improving the maintainability of the device.

[0043] In summary, the anti-jamming vibration feeding device of this screw machine uses the rotation of the positive and negative thread screws 602 in the adjusting component 6 to drive the movement of the sleeve 603 and the clamping plate 605, thereby flexibly adjusting the position of the first guide plate 501, realizing flexible adjustment of the size of the feeding port, effectively avoiding jamming, and can also adapt to screws of different specifications, expanding the application range of the screw machine and improving production flexibility and efficiency.

[0044] The screw machine uses a vibratory feeding device to prevent jamming. The electric push rod 303 in the tilting component 3 extends and retracts to drive the slider 301 to move, so that the material tray 1 rotates around the rotating shaft 101. This allows the tilt angle of the material tray 1 to be adjusted, making the screw feeding smoother, reducing feeding difficulties and interruptions, ensuring the stable operation of the screw machine, and improving production efficiency and product quality.

[0045] Working principle: When the screw machine is working with the anti-jamming vibrating feeding device, the vibrating motor 4 starts and generates vibration, causing the screws in the material tray 1 to move accordingly.

[0046] To adjust the size of the discharge port, the operator rotates the adjusting handle 607, causing the positive and negative thread screw 602 to rotate. Because the two sleeves 603 on the screw 602 have opposite thread directions, the sleeves 603 will move towards or away from each other during rotation. The sleeves 603 drive the clamping plate 605 via the connecting rod 604, and the clamping plate 605 is fixed to the first guide plate 501, thereby causing the first guide plate 501 to move. With the guide assembly 5 plates sequentially hinged and the third guide plate 503 hinged to the side baffle, the size of the discharge port can be flexibly adjusted to accommodate different screw sizes and prevent material jamming.

[0047] When adjusting the tilt angle of the feed tray 1, the electric push rod 303 is extended or retracted. The extension or retraction of the push rod 303 causes the slider 301 to slide at the bottom of the feed tray 1. Since the other end of the push rod 303 is hinged to the fixed block 302 on the base plate 2, the movement of the slider 301 causes the feed tray 1 to rotate around the rotating shaft 101, thereby changing the tilt angle. A suitable tilt angle allows the screws to be conveyed more smoothly under vibration, reducing conveying difficulties and feeding interruptions, ensuring stable operation of the screw machine, and improving production efficiency and product quality.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
