Description

Technical Field

[0001] This application relates to the technical field of metal wire feeding, and in particular to a feeding mechanism for a shot blasting machine for surface treatment of metal wire. Background Technology

[0002] With the widespread use of metal wire, during the feeding process, the metal wire is usually straightened before entering the processing equipment. Usually, several pulley sets are set at the input end of the processing equipment. The wire passes through several pulley sets and is then led out before entering the processing equipment for processing.

[0003] However, during this process, insufficient tension may cause the metal wire to slip on the pulley system, affecting its normal transport and processing accuracy. Excessive tension, on the other hand, may cause overstretching, leading to deformation or even breakage, which not only affects product quality but also increases production costs. Furthermore, existing feeding mechanisms are not flexible enough when handling metal wires of different specifications, requiring significant time and manpower for equipment modification and parameter setting, thus reducing production efficiency. In addition, uneven feeding may occur during the feeding process of shot blasting machines for metal wire surface treatment, resulting in inconsistent shot blasting effects and affecting the quality of the metal wire surface treatment. Summary of the Invention

[0004] To overcome the problems mentioned in the background art, the present invention provides a feeding mechanism for a shot blasting machine for surface treatment of metal wires, which can automatically adjust the tension according to different specifications of metal wires, thereby improving the smoothness of the metal wires during the conveying process.

[0005] This application provides a feeding mechanism for a shot blasting machine used for surface treatment of metal wires, which adopts the following technical solution: A feeding mechanism for a shot blasting machine for surface treatment of metal wire includes a feeding rack, on which the wire is wound. The counterweight mechanism allows the wire to pass around after being output from the feed rack, and the counterweight mechanism applies appropriate tension to the wire; The base is located outside the counterweight mechanism; A frame, the frame being rotatably mounted on top of the frame; The first traction wheel is rotatably mounted on the top of the frame, and the wire passes around the first traction wheel after being output from the counterweight mechanism; A height adjustment mechanism is provided between the base and the frame to adjust the height of the first traction wheel from the working ground.

[0006] By adopting the above technical solution, the wire is wound on the feeding rack and, after exiting the feeding rack, passes around the counterweight mechanism. The counterweight mechanism automatically adjusts the tension applied to the wire according to its specifications and weight, ensuring that the wire maintains appropriate tension during conveying and preventing slippage or excessive stretching. Simultaneously, the frame is rotatably mounted above the base, and a height adjustment mechanism is located between the base and the frame. This mechanism allows for adjustment of the height of the first traction wheel from the working ground as needed, enabling better alignment of the metal wire during feeding, improving the smoothness of the wire conveying process, and ensuring the quality of the metal wire surface treatment.

[0007] Preferably, the height adjustment mechanism includes a height adjustment cylinder and a connecting rod, wherein the fixed end of the height adjustment cylinder is rotatably connected to the base and the movable end is rotatably connected to the frame, one end of the connecting rod is fixed to the base and the other end extends to the frame and engages with the frame.

[0008] By adopting the above technical solution, under the combined action of the height-adjusting cylinder and the connecting rod, when the movable end of the height-adjusting cylinder extends or retracts, it will drive the frame to rotate around the base, thereby realizing the adjustment of the height of the first traction wheel from the working ground. Adjusting the frame height changes the height of the traction wheels, allowing for better matching with the material's position, precise traction, improved work efficiency, and better adjustment of the wire tension.

[0009] Preferably, the frame includes a connecting part and an extension part. The connecting part is rotatably connected to the base via a shaft. The extension part is inclined from the outside to the connecting part and is fixedly connected to the connecting part.

[0010] By adopting the above technical solution, the connecting part is rotatably connected to the base via a shaft, realizing the rotational cooperation between the frame and the base, allowing the frame to rotate around the base to adjust the height of the first traction wheel. The extension part is inclined from the outside to the connecting part, which can provide more space and convenience for wire installation.

[0011] Preferably, the side wall of the base is rotatably connected to a second traction wheel and a third traction wheel, wherein the second traction wheel is disposed between the first traction wheel and the third traction wheel, and the height of the second traction wheel from the working ground is lower than the height of the third traction wheel from the working ground.

[0012] By adopting the above technical solution, the second and third traction wheels can further guide and traction the wire. The second traction wheel is positioned lower, which can provide initial guidance and support to the wire after it passes around the first traction wheel, making the wire conveying more stable. The third traction wheel is positioned higher, which can further adjust the direction and tension of the wire, ensuring that the wire can enter the subsequent processing equipment at a suitable angle and tension, thereby improving the stability and reliability of the entire feeding process.

[0013] Preferably, the frame is further provided with a straightening guide wheel assembly, which includes two straightening guide wheels arranged in parallel, and there is a fitting gap between them for the wire to pass through. The wire first passes through the fitting gap and then goes around the outer wall of the first traction wheel.

[0014] By adopting the above technical solution, when the wire passes through the mating gap of the straightening guide wheel group, the two straightening guide wheels will exert a squeezing and straightening effect on the wire, eliminating the bending and deformation that may occur during the conveying process, keeping the wire in a straight state, and then the wire passes around the outer wall of the first traction wheel, ensuring that the wire has good straightness before entering the subsequent processing equipment, thereby improving the quality and effect of metal wire surface treatment.

[0015] Preferably, the straightening guide wheel assembly is externally rotatably connected to a first guide wheel and a second guide wheel. The first guide wheel and the second guide wheel are arranged at different heights. The first guide wheel is located at the input end of the straightening guide wheel assembly, and the second guide wheel is located at the output end of the straightening guide wheel assembly. The wire first passes around the first guide wheel, then passes through the mating gap, and then passes around the outer wall of the second guide wheel.

[0016] By adopting the above technical solution, the first guide wheel guides the wire to the input end of the straightening guide wheel assembly, allowing the wire to smoothly enter the mating gap for straightening. The second guide wheel then leads the straightened wire out from the output end of the straightening guide wheel assembly and guides it to the first traction wheel, making the wire's conveying path smoother, reducing friction and jamming during conveying, and improving feeding efficiency. Therefore, the combined action of the first and second guide wheels can guide and transition the wire.

[0017] Preferably, the counterweight mechanism includes a counterweight slide rail, a counterweight slider, a fixed wheel, and a counterweight wheel. The counterweight slide rail is disposed outside the feed rack. The counterweight slider is slidably connected to the counterweight slide rail and can slide vertically along the counterweight slide rail. The fixed wheel is rotatably mounted on the top of the counterweight slide rail, and the counterweight wheel is rotatably mounted on the side wall of the counterweight slider. The wire passes sequentially around the fixed wheel and the counterweight wheel, and then around the first guide wheel.

[0018] By adopting the above technical solution, after the wire passes over the fixed wheel and the counterweight wheel, the counterweight slider slides vertically on the counterweight slide rail according to the tension and weight of the wire. When the tension of the wire increases, the counterweight slider slides upward to reduce the tension on the wire; when the tension of the wire decreases, the counterweight slider slides downward to increase the tension on the wire. This automatically adjusts the tension of the wire, ensuring that the wire maintains appropriate tension during transportation and preventing slippage or overstretching.

[0019] Preferably, the counterweight mechanism further includes at least one directional roller, which is rotatably connected to the top of the counterweight slide rail and close to the top surface of the fixed roller. An assembly gap is left between the directional roller and the fixed roller, and the wire passes through the assembly gap after being output from the feed rack.

[0020] By adopting the above technical solution, the setting of the directional roller can guide and position the wire, enabling the wire to accurately pass around the fixed roller and the counterweight roller, avoiding the wire from deviating or tangling during the conveying process; at the same time, the setting of the assembly gap can ensure the smooth passage of the wire, reduce the friction between the wire and the directional roller and the fixed roller, and improve the conveying efficiency and stability of the wire.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. The wire is wound on the feed rack and passes through the counterweight mechanism after being output from the feed rack. The counterweight mechanism automatically adjusts the tension applied to the wire according to the specifications and weight of the wire to ensure that the wire maintains appropriate tension during the conveying process and avoids slippage or excessive stretching. 2. The frame is rotatably mounted on the base. The height adjustment mechanism is located between the base and the frame. It can adjust the height of the first traction wheel from the working ground according to actual needs, so that the wire can be better organized during the feeding process, thereby improving the smoothness of the wire conveying process and ensuring the quality of the wire surface treatment.

Detailed Implementation

[0025] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0026] This application discloses a feeding mechanism for a shot blasting machine used for surface treatment of metal wires.

[0027] Reference Figure 1 and Figure 2 A feeding mechanism for a shot blasting machine for surface treatment of metal wire includes a feeding frame 1, a counterweight mechanism 2, a frame 3, a first traction wheel 41, a base 5, and a height adjustment mechanism 6. The feeding frame 1 is used to wind wire 7, and the counterweight mechanism 2 applies appropriate tension to the wire 7 output from the feeding frame 1. The feeding frame 1, the counterweight mechanism 2, and the base 5 are sequentially arranged on the working ground. The frame 3 is rotatably mounted above the base 5 via a shaft. The first traction wheel 41 is rotatably mounted on the top of the frame 3. The height adjustment mechanism 6 is located between the base 5 and the frame 3 to adjust the height of the first traction wheel 41 from the working ground. In this application, the counterweight mechanism 2 applies appropriate tension according to the actual situation of the wire 7 to avoid slippage, deformation, or breakage of the wire 7. The height adjustment mechanism 6 adjusts the height of the first traction wheel 41 as needed to adapt to different processing requirements of the wire 7, ensuring stable tension of the metal wire 7, flexible adjustment of the feeding height, and ensuring uniform feeding.

[0028] Specifically, the feeding rack 1 is a rack for storing metal wire 7, including a base 11 and multiple support plates 12. The base 11 is preferably a circular base 11, and the multiple support plates 12 are evenly arranged on the base 11. The support plates 12 are welded and fixed to the base 11. Of course, fixing armholes can also be added to the support plates 12 to enhance the structural stability of the entire feeding rack 1. Users can wind the wire 7 around the outer wall of the feeding rack 1 to make the feeding of the wire 7 more orderly.

[0029] Reference Figure 1 and Figure 2The counterweight mechanism 2 is located at the output end of the feed rack 1. The counterweight mechanism 2 includes a counterweight slide rail 21, a counterweight slider 22, a fixed wheel 23, and a counterweight wheel 24. The counterweight slide rail 21 is vertically installed on the outside of the feed rack 1 and can be fixed to the working ground by bolts. The counterweight slider 22 slides in contact with the counterweight slide rail 21 and can slide along the counterweight slide rail 21 in the vertical direction. Specifically, a pulley or ball bearing can be provided inside the counterweight slider 22 to reduce the friction between it and the counterweight slide rail 21.

[0030] The fixed wheel 23 is rotatably mounted on the top of the counterweight slide rail 21, and the counterweight wheel 24 is rotatably mounted on the side wall of the counterweight slider 22. In addition, the counterweight mechanism 2 also includes at least one directional wheel 25. In this embodiment, there are two directional wheels 25. The directional wheels 25 are rotatably connected to the top of the counterweight slide rail 21 and close to the top surface of the fixed wheel 23. The two directional wheels 25 are rotatably arranged at different heights around the fixed wheel 23, and an assembly gap is left between the directional wheels 25 and the fixed wheel 23.

[0031] Furthermore, the fixed wheel 23 and the counterweight wheel 24 have the same shape and structure, and both of them have grooves on their outer walls. The number of grooves depends on the situation. The grooves are semi-circular grooves that are opened downward along the outer wall of the wheel, making the feeding process of the wire 7 more orderly.

[0032] Reference Figure 2 The base 5 is located outside the counterweight mechanism 2. The frame 3 is rotatably mounted above the frame 3. The frame 3 includes a connecting part 31 and an extension part 32. The connecting part 31 is rotatably connected to the base 5 via a shaft. The extension part 32 is inclined from the outside to the connecting part 31 and is fixedly connected to the connecting part 31. The height adjustment mechanism 6 includes a height adjustment cylinder 61 and a connecting rod 62. The fixed end of the height adjustment cylinder 61 is rotatably connected to the base 5, and the movable end is rotatably connected to the frame 3. One end of the connecting rod 62 is fixed to the base 5, and the other end extends to the frame 3 and engages with the frame 3. The connecting rod 62 limits the maximum tilt angle between the frame 3 and the base 5.

[0033] Furthermore, a first traction wheel 41 is rotatably mounted on the top of the frame 3, and a straightening guide wheel 33 group is also provided near the input end of the first traction wheel 41 on the frame 3. The straightening guide wheel 33 group includes two straightening guide wheels 33 arranged side by side, with a fitting gap between them for the wire 7 to pass through. A first guide wheel 34 and a second guide wheel 35 are rotatably connected to the outside of the straightening guide wheel 33 group. The first guide wheel 34 and the second guide wheel 35 are arranged at different heights. The first guide wheel 34 is located at the input end of the straightening guide wheel 33 group, and the second guide wheel 35 is located at the output end of the straightening guide wheel 33 group.

[0034] In this application, a second traction wheel 42 and a third traction wheel 43 are rotatably connected to the side wall of the base 5. The second traction wheel 42 is disposed between the first traction wheel 41 and the second traction wheel 42, and the height of the second traction wheel 42 from the working ground is lower than the height of the third traction wheel 43 from the working ground.

[0035] In practical applications, the wire 7 is first output from the feed rack 1, passes through the assembly gap between the directional roller 25 and the fixed roller 23, then passes around the counterweight roller 24 and the first guide roller 34, then passes through the fitting gap between the two straightening guide rollers 33, and then passes around the second guide roller 35, the first traction roller 41, the second traction roller 42 and the third traction roller 43.

[0036] During this process, the height adjustment mechanism 6 can adjust the height of the first traction wheel 41 from the working ground as needed. The counterweight slider 22 will slide vertically on the counterweight slide rail 21 according to the tension and weight of the wire 7. When the tension of the wire 7 increases, the counterweight slider 22 slides upward to reduce the tension on the wire 7 and prevent the wire 7 from being overstretched; when the tension of the wire 7 decreases, the counterweight slider 22 slides downward to increase the tension on the wire 7 and prevent the wire 7 from slipping. At the same time, the straightening guide wheels 33 straighten the wire 7, eliminating the bending and deformation that may occur during the conveying process, and keeping the wire 7 in a straight state. The second traction wheel 42 and the third traction wheel 43 further guide and pull the wire 7. The second traction wheel 42 is positioned lower, providing initial guidance and support for the wire 7, making the wire 7 transport more smoothly. The third traction wheel 43 is positioned higher, further adjusting the direction and tension of the wire 7, so that the wire 7 can be better organized during the feeding process, improving the smoothness of the metal wire 7 during the transport process, and ensuring the quality of the surface treatment of the metal wire 7.

These embodiments are merely explanations of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of this application should be covered within the scope of protection of this application.
