Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of metal wire processing equipment, specifically to a chain grinding machine. Background Technology
[0002] Precious metals are highly stable, and due to their limited production and unique luster, they are very popular. To meet market demand, especially for precious metals like gold and silver, they are processed into various unique shapes, such as bracelets, necklaces, etc., for wearing. Slender items like bracelets and necklaces are generally mass-produced by machines. After processing, burrs inevitably remain on the edges of the jewelry, and it's difficult to directly process them into aesthetically pleasing curves, resulting in a less desirable feel. If hand-polishing is attempted, the limited size of the slender pieces makes it inefficient, difficult to achieve a perfectly smooth finish, and results in inconsistent dimensions, affecting the overall quality of the jewelry. Utility Model Content
[0003] To overcome the above-mentioned defects, the purpose of this utility model is to provide a chain grinding machine, which can grind the edges of metal wires by setting multiple grinding wheels, thereby improving processing efficiency and making it easier to meet the needs of jewelry processing.
[0004] To achieve the above objectives, this utility model provides a chain grinding machine with a frame. The frame is equipped with a protective cover, and the protective cover has a feed inlet and a discharge outlet on both sides. The feed inlet is connected to a feed pressure roller, and the discharge outlet is equipped with a discharge pressure roller. The feed pressure roller is driven by a feed motor, and the discharge pressure roller is driven by a discharge motor. A grinding mechanism is provided inside the protective cover. The grinding mechanism includes a grinding wheel and a material support wheel. The material support wheel has a limiting groove in the middle. The material support wheel is fixedly connected to the frame by an adjusting plate and an adjusting nut, and the material support wheel is close to the grinding wheel. The wire to be processed is clamped between the grinding wheel and the material support wheel.
[0005] Preferably, the grinding wheel is a driving wheel, and the material support wheel is a driven wheel. The material support wheel is rotatably mounted on the end of the adjusting plate and close to the grinding wheel.
[0006] Preferably, the material support roller includes a first material support roller and a second material support roller, and the first material support roller and the second material support roller are provided with adjustment holes, which are used to adjust the gap distance between the first material support roller and the second material support roller.
[0007] Preferably, the grinding wheels are in two sets, with two grinding wheels in each set, and the two sets of grinding wheels are connected to a servo motor via a pulley mechanism.
[0008] Preferably, the bottom of the protective cover is provided with a dust discharge hole, which is connected to a dust collection box.
[0009] The beneficial technical effects achieved by this utility model after adopting the above technical solution are as follows:
[0010] 1. When the feed roller and discharge roller drive the wire, the edge of the wire can be polished by a polishing mechanism consisting of multiple polishing wheels and material support wheels inside the protective cover, making it smoother and meeting the processing requirements of metal jewelry.
[0011] 2. Because a material support wheel consisting of a first material support wheel and a second material support wheel is provided, and the first material support wheel and the second material support wheel are provided with adjustment holes, the gap between the first material support wheel and the second material support wheel can be adjusted by using the adjustment screw in the adjustment hole, so as to meet the movement requirements of different types of wires and ensure that the contact distance between the moving wire and the grinding wheel is basically the same. In this way, the curvature of the metal wire after grinding is basically the same, which is more aesthetically pleasing. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.
[0020] See Figures 1-3This utility model provides a chain grinding machine, including a frame 1. The frame 1 is equipped with a protective cover 11. The protective cover 11 has a feed inlet 12 and a discharge outlet 13 on both sides. The feed inlet 12 is connected to a feed roller 14, and the discharge outlet 13 is equipped with a discharge roller 15. The feed roller 14 is driven by a feed motor, and the discharge roller 15 is driven by a discharge motor. Taking precious metal gold as an example, this utility model mainly grinds the sharp edges of pre-formed rectangular wire 3 into an arc shape. A certain amount of dust and debris will be generated during the grinding process. Since precious metals can be recycled, a protective cover 11 is needed to facilitate recycling. Additionally, a dust discharge hole 16 can be provided at the bottom of the protective cover 11, which is connected to a dust collection box. A vacuum pump can generally be used to utilize the vacuum suction principle to recover small metal dust particles. The dust particles at the bottom can also be cleaned with a special acid or alkali solution for more thorough recycling.
[0021] The frame 1 provides support. The two ends of the wire 3 to be ground are clamped by the feed roller 14 and the discharge roller 15, respectively. The feed motor and discharge motor ensure that the wire 3 remains taut at all times. A grinding mechanism 2 is located inside the protective cover 11. The grinding mechanism 2 includes a grinding wheel 21 and a support roller 22. The support roller 22 has a limiting groove 221 in the middle. The support roller 22 is fixedly connected to the frame 1 via an adjusting plate 23 and an adjusting nut 24, and is positioned close to the grinding wheel 21. The wire 3 to be processed is clamped between the grinding wheel 21 and the support roller 22. (See also...) Figure 2 After entering through the feed inlet 12, the wire 3 is pressed by the nearest support roller 22, ensuring it is in contact with the end face of the grinding roller 21. After being ground by multiple grinding rollers 21, the outer surface of the wire 3 can achieve a smooth finish, which is especially suitable for wire 3 with rectangular blocks. The two ends of the wire 3 are clamped and fixed by the feed roller 14 and the discharge roller 15, respectively, and the power in the middle comes from multiple grinding rollers 21. The adjusting nut 24 is used to adjust the position and distance of the adjusting plate 23 and the angle of the adjusting plate 23 to prevent the curvature from being too small and affecting the movement of the wire 3.
[0022] The grinding wheel 21 of this invention is the driving wheel, powered by a servo motor 25 at the bottom. The material support wheel 22 is the driven wheel, mainly used for support and limiting. The material support wheel 22 is rotatably mounted on the end of the adjusting plate 23 and close to the grinding wheel 21. The adjusting plate 23 is used to adjust the position of the material support wheel 22, mainly to adjust the gap between the material support wheel 22 and the grinding wheel 21, so that it can be adapted to the hardness of various types of wire 3. The greater the hardness, the less likely the wire 3 is to bend.
[0023] The material support roller 22 of this utility model includes a first material support roller 22 and a second material support roller 22. Both the first and second material support rollers 22 are provided with adjustment holes, and adjustment screws are installed in the adjustment holes. The adjustment screws are used to adjust the gap between the first and second material support rollers 22. Both the first and second material support rollers 22 are fixed to the rotating shaft by screws. To facilitate installation, during processing, a flat surface is milled on the circular end face of the first and second material support rollers 22, and then adjustment holes are made. The first and second material support rollers 22 are respectively fixed by the fastening screws in the adjustment holes. The gap between them is adapted to the diameter of the wire 3 and generally requires multiple adjustments to prevent wire jamming.
[0024] The grinding wheels 21 of this invention are in two sets, with two grinding wheels 21 in each set. Each set of grinding wheels 21 is connected to a servo motor 25 via a pulley mechanism 26. The servo motor 25 provides power to the grinding wheels 21. In the illustration, four grinding wheels 21 are shown; the top two are connected to the servo motor 25 by a belt, and the bottom two are connected by another belt. Generally, one servo motor 25 is sufficient, ensuring consistent speed transmission and easy control.
[0025] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
