Description
Technical Field
[0001] This utility model belongs to the technical field of metal processing equipment, specifically relating to a material conveying and feeding structure for a wire rolling machine. Background Technology
[0002] In the metal processing industry, thread rolling machines are key equipment used for threading materials such as metal rods. The material feeding stage is crucial in the thread rolling machine's workflow. Traditional thread rolling machines typically employ a relatively simple material feeding structure, using a conveyor belt, feeding hopper, and discharge hopper to lift the metal rod to be processed from its initial position and transport it into the thread rolling machine's hopper. Specifically, the metal rod is first placed in the feeding hopper, then lifted to the top by the conveyor belt, and subsequently discharged downwards through the discharge hopper into the thread rolling machine's hopper, thus entering the thread rolling process.
[0003] However, the existing material conveying and feeding method has significant problems. When the metal rod to be processed is lifted and conveyed upwards into the hopper of the thread rolling machine by the material conveying and feeding structure, the metal rod lifted to the top will be discharged downwards into the hopper through the discharge hopper. During this process, due to the lack of effective cushioning measures, the metal rod discharged from the discharge hopper often falls directly and impacts the hopper. This not only easily damages the metal rod, causing defects such as dents and deformation on the surface, affecting the accuracy and quality of subsequent thread rolling, but also damages the hopper due to frequent and strong impacts, shortening its service life and increasing equipment maintenance costs. In addition, this direct impact may also cause instability during equipment operation, affecting the overall efficiency and stability of the thread rolling machine. Utility Model Content
[0004] The purpose of this utility model is to provide a material conveying and feeding structure for a wire rolling machine, in order to solve the problems mentioned in the background art. The traditional material conveying and feeding structure for wire rolling machines uses a conveyor belt, a feeding hopper, and a discharging hopper to transport the metal rod to be processed to the wire rolling machine hopper. However, due to the lack of effective buffering measures, the metal rod to be processed falls directly into the wire rolling machine hopper when it is discharged through the discharging hopper, which will damage the metal rod, affect the processing accuracy and quality, damage the wire rolling machine hopper, increase maintenance costs, and may also affect the operating efficiency and stability of the equipment.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a material conveying and feeding structure for a wire rolling machine, comprising two conveying fixed side plates and a conveying fixed bottom plate connected and fixed to the outer wall of the inclined surface at the front end of the two conveying fixed side plates. The conveying fixed side plates are arranged at an inclined angle of front-up and rear-down. A conveyor belt is arranged between the two conveying fixed side plates. Multiple conveying lifting baffles are fixed at equal intervals on the outer wall of the conveyor belt. A discharge hopper is connected to the outer top of the two conveying fixed side plates. The discharge opening of the discharge hopper faces downward. A buffer discharge device is provided at the bottom opening of the discharge hopper.
[0006] Preferably, the buffer discharge device includes a U-shaped fixing frame, a U-shaped buffer cover, and a buffer baffle. The U-shaped buffer cover is located at the lower end of the discharge opening at the bottom of the discharge hopper. The front end and the outer walls of the left and right ends of the U-shaped buffer cover are connected to the U-shaped fixing frame. The upper half of the U-shaped fixing frame is attached to the left and right ends and the front outer wall of the discharge position of the discharge hopper. The U-shaped fixing frame is fixedly connected to the discharge hopper by multiple screws. A buffer baffle is provided inside the U-shaped buffer cover.
[0007] Preferably, the buffer discharge device further includes an adjusting groove, an adjusting screw, and a fixing nut. The left and right ends of the U-shaped buffer cover are provided with adjusting grooves, and the left and right ends of the buffer stop are welded with adjusting screws. The two adjusting screws pass through the adjusting grooves inside the left and right ends of the U-shaped buffer cover, and the two adjusting screws are threaded with fixing nuts on the outside, and the two fixing nuts are located outside the left and right ends of the U-shaped buffer cover.
[0008] Preferably, the diameter of the adjusting screw is smaller than the diameter of the buffer stop, and the diameter of the buffer stop is larger than the height of the adjusting groove. The adjusting screw can slide back and forth in the adjusting groove, and the position of the buffer stop inside the U-shaped buffer cover can be changed when the adjusting screw slides back and forth.
[0009] Preferably, the longitudinal width of the U-shaped buffer cover is greater than the longitudinal width at the discharge port of the discharge hopper, and the buffer stop can slide backward to the rear side of the discharge port of the discharge hopper when not in use.
[0010] Preferably, a feeding hopper is connected to the outer wall of the lower inclined surface at the center of the rear end of the two conveying fixed side plates. The rear end of the feeding hopper is set with an inclined surface at the front lower and the rear upper to smoothly guide the metal rod to be processed inside the feeding hopper to slide onto the conveying lifting baffle.
[0011] Preferably, a base is provided below the feeding hopper and the conveying fixed side plate, and the bottom left and right ends of the conveying fixed base plate are fixedly connected to the base, as are the bottom of the feeding hopper near the four corners and the base, by fixed support columns.
[0012] Preferably, a conveying motor is provided on the left side of the discharge hopper. The conveying motor is fixed to the outer wall of the top left end of the conveying fixed side plate by a flange and screws. Multiple transmission rollers are equidistantly connected between the two conveying fixed side plates. The multiple transmission rollers are all located inside the conveyor belt, and the conveying motor is connected to the transmission roller inside the top end of the conveyor belt.
[0013] Preferably, the outer wall of the inclined surface at the rear end of the two conveying fixed side plates is also connected to a protective cover, and the protective cover is located between the feeding hopper and the discharging hopper.
[0014] Compared with the prior art, this utility model provides a material conveying and feeding structure for a wire rolling machine, which has the following beneficial effects:
[0015] This invention adds a novel buffer discharge device to the discharge port at the bottom of the hopper of the material conveying and feeding structure of the wire rolling machine. When the conveyor belt conveys the metal rod to be processed upward through the conveyor lifting baffle to the inner area of the discharge hopper and discharges it through the discharge hopper, the discharged metal rod will be discharged directly downward through the discharge port of the discharge hopper. The buffer discharge device can buffer the downward discharge of the metal rod. Specifically, when the metal rod falls downward through the discharge hopper, it will collide with the buffer stop bar inside the U-shaped buffer cover. This process effectively buffers the impact force of the falling metal rod, preventing it from directly impacting the wire rolling machine hopper at high speed. This protects the metal rod from damage due to excessive impact, ensuring its quality, and reduces the impact on the hopper and subsequent processing equipment, extending the service life of the equipment. Secondly, in terms of flexibility, the position of the buffer stop bar inside the U-shaped buffer cover is adjustable. It can flexibly change the buffer position according to the size, weight, and other differences of different models of metal rods to be processed, achieving targeted buffering and greatly improving the applicability of the device.

[0022] 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.
[0023] This utility model provides, for example Figure 1-5 The material conveying and feeding structure of the yarn rolling machine shown includes two conveying fixed side plates 5 and a conveying fixed base plate 4 connected and fixed to the outer wall of the inclined front surface of the two conveying fixed side plates 5. The conveying fixed side plates 5 are set at an inclined angle of front-up and rear-down, providing a basic support structure for the entire conveying process. The conveying fixed base plate 4 is connected to the outer wall of the inclined front surface of the two conveying fixed side plates 5, and together with the side plates, they form a stable conveying frame. A conveyor belt 10 is arranged between the two conveying fixed side plates 5. Multiple conveying lifting baffles 11 are fixed at equal intervals on the outer wall of the conveyor belt 10. A discharge hopper 9 is connected to the top of the two conveying fixed side plates 5. The discharge opening of the discharge hopper 9 faces downward. The rear end of the two conveying fixed side plates 5... A feeding hopper 2 is connected to the outer wall of the lower inclined surface at the center. The rear end of the feeding hopper 2 is set with a front-lower and rear-upward inclined surface to smoothly guide the metal rod to be processed inside the feeding hopper 2 to slide onto the conveyor lifting baffle 11. This inclined angle design utilizes gravity to allow the metal rod to be processed inside the feeding hopper 2 to slide smoothly down and naturally slide onto the conveyor lifting baffle 11, which is fixed at equal intervals on the outer wall of the conveyor belt 10. The outer wall of the inclined surface at the rear end of the two conveyor fixed side plates 5 is also connected to a protective cover 6, which is located between the feeding hopper 2 and the discharge hopper 9. The protective cover 6 can play a protective role, preventing material splashing and external debris from entering the conveying device, ensuring the normal operation of the equipment and the safety of the operators.
[0024] like Figure 1 , Figure 2 and Figure 3As shown, a base 1 is installed below the feeding hopper 2 and the conveying fixed side plate 5. The bottom left and right ends of the conveying fixed base plate 4 are fixedly connected to the base 1, and the bottom of the feeding hopper 2 near the four corners is also fixedly connected to the base 1 via fixed support columns 3. Throughout the conveying process, the base 1 provides stable support for the conveying fixed base plate 4 and the feeding hopper 2. The fixed support columns 3 ensure the overall stability of the device. A conveying motor 8 is installed on the left side of the discharge hopper 9. The conveying motor 8 is fixed to the outer wall of the top left end of the conveying fixed side plate 5 via flanges and screws. Multiple drive rollers are equidistantly connected between the two conveying fixed side plates 5. All drive rollers are located on the conveying fixed side plate 5. Inside the conveyor belt 10, the conveyor motor 8 is connected to the transmission roller inside the top of the conveyor belt 10. After the motor starts, it drives the transmission roller inside the top of the conveyor belt 10 to rotate. Since multiple transmission rollers are equidistantly connected between the two conveyor fixed side plates 5 and located inside the conveyor belt 10, they work together to drive the conveyor belt 10 to circulate. During the operation of the conveyor belt 10, the conveyor lifting baffle 11 on its outer wall moves accordingly, conveying the metal rod to be processed upward. As the conveyor belt 10 continues to operate, the metal rod to be processed is conveyed to the discharge hopper 9 connected to the outside of the top of the two conveyor fixed side plates 5. The discharge opening of the discharge hopper 9 faces downward, so that the metal rod to be processed is discharged from the discharge hopper 9 and enters the subsequent processing process.
[0025] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, a buffer discharge device 7 is provided at the bottom opening of the discharge hopper 9. The buffer discharge device 7 includes a U-shaped fixing frame 12, a loop-shaped buffer cover 13, and a buffer stop bar 14. The loop-shaped buffer cover 13 is located at the lower end of the discharge opening at the bottom of the discharge hopper 9. The U-shaped fixing frame 12 is connected to the front end and the outer walls of the left and right ends of the loop-shaped buffer cover 13. The upper half of the U-shaped fixing frame 12 is attached to the left and right ends and the front outer wall of the discharge position of the discharge hopper 9, and the U-shaped fixing frame 12 is fixedly connected to the discharge hopper 9 by multiple screws. The buffer stop bar 14 is provided inside the loop-shaped buffer cover 13. The U-shaped fixing frame 12, the loop-shaped buffer cover 13, and the buffer stop bar 14 together constitute the basic buffer structure. The upper half of the U-shaped fixing frame 12 is tightly attached to the left and right ends and the front outer wall of the discharge position of the discharge hopper 9, and is firmly secured by multiple screws. The buffer discharge device 7 is fixedly connected to the discharge hopper 9 to ensure that the entire buffer discharge device 7 is stably installed below the bottom opening of the discharge hopper 9. The U-shaped buffer cover 13 is connected to the U-shaped fixing frame 12 and is located below the bottom discharge opening of the discharge hopper 9. It provides installation space for the buffer stop bar 14 and also plays a certain role in protection and guidance during the buffering process. The buffer discharge device 7 also includes an adjusting groove 15, an adjusting screw 16, and a fixing nut 17. The adjusting groove 15 is provided inside both the left and right ends of the U-shaped buffer cover 13. The adjusting screw 16 is welded to both the left and right ends of the buffer stop bar 14. The two adjusting screws 16 pass through the adjusting grooves 15 inside the left and right ends of the U-shaped buffer cover 13 respectively. The fixing nuts 17 are threaded onto the outside of both adjusting screws 16, and the two fixing nuts 17 are located outside the left and right ends of the U-shaped buffer cover 13 respectively.
[0026] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the diameter of the adjusting screw 16 is smaller than the diameter of the buffer stop 14, and the diameter of the buffer stop 14 is larger than the height of the adjusting groove 15. The adjusting screw 16 can slide back and forth in the adjusting groove 15. When the adjusting screw 16 slides back and forth, it can change the position of the buffer stop 14 inside the U-shaped buffer cover 13. The setting of the adjusting groove 15, the adjusting screw 16, and the fixing nut 17 gives the buffer stop 14 the function of position adjustment. The U-shaped buffer cover 13 has adjusting grooves 15 inside both the left and right ends. The adjusting screws 16 welded at both ends pass through the corresponding adjusting grooves 15. The diameter of the adjusting screws 16 is smaller than the diameter of the buffer stop 14, and the diameter of the buffer stop 14 is larger than the height of the adjusting groove 15. This size design ensures the structural strength of the buffer stop 14 while allowing the adjusting screws 16 to slide flexibly back and forth in the adjusting grooves 15. The longitudinal width of the U-shaped buffer cover 13 is larger than the longitudinal width at the discharge port of the discharge hopper 9. When not in use, the buffer stop 14 can slide backward to the rear side of the discharge port of the discharge hopper 9. When the position of the buffer stop 14 needs to be adjusted, the fixing nuts 17 located on the outside of the left and right ends of the U-shaped buffer cover 13 are rotated. Since the adjusting screw 16 and the fixing nut 17 are threadedly connected, as the nut rotates, the adjusting screw 16 will move back and forth along the axis in the adjusting slide 15, thereby driving the buffer stop 14 to change its position inside the U-shaped buffer cover 13. This adjustment function allows the buffer stop 14 to be flexibly adjusted to the optimal buffer position according to the different models of the metal rod to be processed (such as length, diameter, weight, etc.) to achieve the ideal buffering effect. The longitudinal width of the U-shaped buffer cover 13 is greater than the longitudinal width at the discharge port of the discharge hopper 9. This design is of great significance. When the buffer stop 14 is not in use, it can be slid backward to the rear side of the discharge port of the discharge hopper 9. This design does not affect the normal discharge of the discharge hopper 9, and it is convenient to store the buffer stop 14 in a position that does not affect the operation when the equipment is being maintained, cleaned, or when the buffering function is not needed. This improves the flexibility of the device and the overall operability of the equipment.

Although the present utility model 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.
