Description
Technical Field
[0001] The utility model relates to the technical field of kiln feeding, in particular to a kiln feeding noise reduction structure. Background Art
[0002] Kilns are equipment made of refractory materials for firing products and are essential facilities in pottery molding. In the history of ceramic firing over tens of thousands of years, humans have accumulated a wealth of kiln-making styles and experience. From the open-air pile firing and pit-building firing in primitive society to the steamed bun-shaped rising flame round kiln, semi-downdraft horseshoe kiln, half-slope dragon kiln, duck egg-shaped kiln, and today's indoor gas kiln and electric kiln, kiln technology is constantly improving and developing.
[0003] Kilns can be used to fire many kinds of materials such as ceramic products, such as ceramic tableware, vases, sculptures, etc. To fire ceramic products, the clay needs to be heated to a high temperature and sintered to solidify and shape; glass products: kilns can be used to make glass products, such as glassware, architectural glass, automotive glass, etc. To fire glass products, the glass blank needs to be heated to a high temperature to melt and shape; metal processing: kilns can be used for metal heating treatment, such as heat treatment, annealing, quenching, etc. Metals can improve their mechanical properties, corrosion resistance and wear resistance at high temperatures. In the process of processing and heat treatment of metal materials, the traditional method of loading and unloading materials is to feed materials through conveyor belts. When metal parts slide into the kiln, because the gravity of the metal parts is large, the friction between the metal parts and the conveyor belt is also high, which makes the noise generated when sliding down. In addition, the furnace charge falls under the action of gravity when it is lowered into the kiln, and the collision between the furnace charges will also generate a lot of noise. Utility Model Content
[0004] The purpose of the utility model is to provide a kiln charging noise reduction structure to solve the problems raised in the above background technology.
[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:
[0006] A kiln charging noise reduction structure comprises wheels and a mobile frame; a lifting component is fixedly connected above the mobile frame, a feeding chute is fixedly connected to the upper end of the lifting component, one end of the feeding chute is closed and the other end is open, a buffer component is provided near the open end of the feeding chute, and the buffer component is fixedly connected to the side of the lifting component; the buffer component is used to buffer metal workpieces falling from one side of the feeding chute; a pushing component is fixedly provided at the closed end of the feeding chute, and the pushing component can push the workpiece to move on the feeding chute.
[0007] When heat treating metal workpieces, the lifting component is started, and the lifting component descends, driving the loading trough to descend to a height that the staff can operate. Then the staff puts the workpiece into the closed end of the loading trough. After the metal workpiece is placed on the loading trough, the pushing component is started, and the metal workpiece is pushed to move by the pushing component. When the metal workpiece is pushed to the opening of the loading trough, the metal workpiece will fall onto the buffer component, and the metal block will be buffered by the buffer component, so that the metal workpiece enters the kiln at a lower speed, thereby reducing the impact force of the metal workpiece impacting the kiln and other workpieces, thereby reducing the noise generated during the impact. In addition, the buffer component can also prevent the impact between metal workpieces from causing damage to the workpiece.
[0008] A further improvement of the technical solution of the utility model is that a plurality of transfer rollers are arranged at the bottom end of the feeding trough, and the transfer rollers are rotatably connected to the side walls of the feeding trough.
[0009] The above-mentioned technical solution is adopted, in which a plurality of transfer rollers are arranged. When the metal workpiece is placed on the bottom end of the loading trough, it is placed on the transfer rollers. The transfer rollers transform the sliding of the metal workpiece during the transmission process into rolling, so that the friction force is greatly reduced, thereby greatly reducing the noise generated by the metal workpiece during the transportation process.
[0010] A further improvement of the technical solution of the utility model is that a plurality of limiting rollers are symmetrically arranged on the side wall of the feeding trough, and the limiting rollers are rotatably connected to the side wall of the feeding trough.
[0011] The above technical solution is adopted, in which a plurality of limiting rollers are provided, and the workpiece can be limited by the limiting rollers. At the same time, when the width of the workpiece is large, the limiting rollers can also be used to prevent friction between the workpiece and the side wall of the feeding trough, thereby reducing the generation of noise.
[0012] A further improvement of the technical solution of the utility model is that the buffer component includes a material receiving box, the upper end of the material receiving box is open, the upper end of the material receiving box is located below the opening end of the feeding trough, a hydraulic cylinder is fixedly connected to the inside of the material receiving box, a piston is slidably provided inside the hydraulic cylinder, a piston rod is fixedly provided on the upper end of the piston, the piston rod is slidably connected to the top of the hydraulic cylinder, a loading plate is fixedly connected to the upper end of the piston rod, a spring is sleeved on the piston rod, hydraulic pipes are provided on both sides of the hydraulic cylinder, one end of the hydraulic pipe is L-shaped, a lifting rod is provided on the top of the hydraulic pipe, the lifting rod is slidably connected to the hydraulic pipe, and a lifting plate is fixedly connected to the upper end of the lifting rod; a material discharge port is provided on one side of the material receiving box, a baffle is provided on the upper end of the material discharge port, the baffle is slidably connected to the material receiving box, and the lifting plate is slidably connected to the material receiving box.
[0013] The above-mentioned technical scheme is adopted. In this scheme, when the workpiece reaches the buffer component, it first falls into the receiving box, and then a loading plate is provided inside the receiving box, and the metal workpiece will fall onto the loading plate. When the gravity of the workpiece on the loading plate is greater than the elastic force of the spring, the hydraulic oil in the hydraulic cylinder is saved, and the loading plate descends to drive the piston to squeeze the hydraulic oil, thereby causing the lifting rod to rise and then driving the baffle to rise. During the whole process, the metal workpiece falls into the receiving box through the buffering of the piston and the spring. It is first buffered so that the metal workpiece can stay in the receiving box, and then enters the furnace through the discharge port, so that the speed of the workpiece entering the furnace is slowed down, the impact is reduced, and the noise is reduced, and the damage to the metal workpiece can also be reduced.
[0014] The further improvement of the technical solution of the utility model is that: a part of an inner side wall of the material receiving box close to the baffle is cut off so that a groove edge is formed between the baffle and the side wall; one side of the lifting plate is protruded and fixedly connected with the baffle.
[0015] By adopting the above technical solution, a groove edge is provided in the solution, and the protruding part on one side of the lifting plate can block the groove edge and play a role of limiting.
[0016] A further improvement of the technical solution of the utility model is that: preferably, the pushing component includes a pushing block, which is slidably connected to the slide rail, an electric push rod is provided on one side of the pushing block, and the fixed end of the electric push rod is fixedly connected to the closed end of the loading trough; the movable end of the electric push rod is fixedly connected to one side of the pushing block.
[0017] The above technical solution is adopted. In this solution, in this embodiment, a push block is provided, and an electric push rod is started when pushing the material. The electric push rod drives the push block to push the metal workpiece to move.
[0018] A further improvement of the technical solution of the utility model is that a weight block is arranged above the wheel plate above the wheel, and the weight block is fixedly connected to the wheel plate.
[0019] By adopting the above technical solution, a weight block is set in the solution, so that the metal workpiece has a larger gravity, which prevents the entire device from moving in the opposite direction of the pushing direction when the metal workpiece is pushed, thereby improving the stability of the device.
[0020] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:
[0021] 1. The utility model provides a kiln feeding noise reduction structure, which pushes the metal workpiece to move by a pushing component. When the metal workpiece is pushed to the opening of the feeding chute, the metal workpiece will fall onto the buffer component. The buffer component buffers the metal block, so that the metal workpiece enters the kiln at a lower speed, thereby reducing the impact force of the metal workpiece impacting the kiln and other workpieces, thereby reducing the noise generated during the impact. In addition, the buffer component can also prevent the impact between the metal workpieces from causing damage to the workpiece.
[0022] 2. The utility model provides a kiln feeding noise reduction structure. By arranging a plurality of transfer rollers, the metal workpiece is placed on the transfer rollers when it is placed on the bottom of the feeding chute. The transfer rollers transform the sliding of the metal workpiece during the transmission into rolling, which greatly reduces the friction force, thereby greatly reducing the noise generated by the metal workpiece during the transportation process.

[0033] In this embodiment, when performing heat treatment on a metal workpiece, the lifting component 3 is started, and the lifting component 3 descends, driving the loading chute 4 to descend, so that the loading chute 4 descends to a height that the staff can operate, and then the staff puts the workpiece into the closed end of the loading chute 4. After the metal workpiece is placed on the loading chute 4, the pushing component 6 is started, and the metal workpiece is pushed to move by the pushing component 6. When the metal workpiece is pushed to the opening of the loading chute 4, the metal workpiece will fall onto the buffer component 5, and the buffer component 5 will buffer the metal block, so that the metal workpiece enters the kiln at a lower speed, thereby reducing the impact force of the metal workpiece on the furnace and other workpieces, thereby reducing the noise generated during the impact, and the buffer component 5 can also prevent the impact between the metal workpieces from causing damage to the workpiece.
[0034] like Figure 3 As shown, in this embodiment, preferably, a plurality of transfer rollers 7 are provided at the bottom end of the loading chute 4 , and the transfer rollers 7 are rotatably connected to the side wall of the loading chute 4 .
[0035] By setting up multiple transfer rollers 7, the metal workpiece is placed on the transfer rollers 7 when placed on the bottom of the loading trough 4. The transfer rollers 7 convert the sliding of the metal workpiece during the transmission into rolling, which greatly reduces the friction force, thereby greatly reducing the noise generated by the metal workpiece during the transportation process.
[0036] like Figure 3 As shown, preferably, a plurality of limiting rollers 8 are symmetrically provided on the side wall of the feeding chute 4 , and the limiting rollers 8 are rotatably connected to the side wall of the feeding chute 4 .
[0037] By setting a plurality of limiting rollers 8, the workpiece can be limited by the limiting rollers 8. Meanwhile, when the width of the workpiece is large, the limiting rollers 8 can be used to prevent friction between the workpiece and the side wall of the feeding trough 4, thereby reducing noise generation.
[0038] Example 2
[0039] like Figure 4-5As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the buffer component 5 includes a material receiving box 9, the upper end of the material receiving box 9 is open, and the upper end opening of the material receiving box 9 is below the open end of the feeding trough 4, and a hydraulic cylinder 10 is fixedly connected inside the material receiving box 9, and a piston is slidably provided inside the hydraulic cylinder 10, and a piston rod is fixedly provided on the upper end of the piston, and the piston rod is slidably connected to the top of the hydraulic cylinder 10, and a loading plate 11 is fixedly connected to the upper end of the piston rod, and a spring 12 is sleeved on the piston rod, and hydraulic pipes 13 are provided on both sides of the hydraulic cylinder 10, one end of the hydraulic pipe 13 is L-shaped, and a lifting rod 14 is provided on the top of the hydraulic pipe 13, and the lifting rod 14 is slidably connected to the hydraulic pipe 13, and a lifting plate 15 is fixedly connected to the upper end of the lifting rod 14; a material discharge port is provided on one side of the material receiving box 9, and a baffle 16 is provided on the upper end of the material discharge port, the baffle 16 is slidably connected to the material receiving box 9, and the lifting plate 15 is slidably connected to the material receiving box 9.
[0040] In this embodiment, when the workpiece reaches the buffer component 5, it first falls into the receiving box 9, and then a loading plate 11 is provided inside the receiving box 9, and the metal workpiece will fall onto the loading plate 11. When the gravity of the workpiece on the loading plate 11 is greater than the elastic force of the spring 12, the hydraulic oil in the hydraulic cylinder 10 is saved, and the loading plate 11 descends to drive the piston to squeeze the hydraulic oil, thereby causing the lifting rod 14 to rise and then driving the baffle 16 to rise. During the whole process, the metal workpiece is buffered by the piston and the spring 12, so that the metal workpiece falls into the receiving box 9 and is first buffered so that the metal workpiece can stay in the receiving box 9, and then enters the kiln through the discharge port, so that the speed of the workpiece entering the kiln is slowed down, the impact is reduced, and the noise is reduced, and the damage to the metal workpiece can also be reduced.
[0041] A portion of the inner side wall of the receiving box 9 close to the baffle 16 is cut away, so that a groove edge 19 is formed between the baffle 16 and the side wall; one side of the lifting plate 15 protrudes and is fixedly connected to the baffle 16 .
[0042] By providing the groove edge 19, the protruding portion on one side of the lifting plate 15 can block the groove edge 19, thus playing a role of limiting.
[0043] Example 3
[0044] like Figure 3 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the pushing component 6 includes a pushing block 17, which is slidably connected to the slide rail, and an electric push rod 18 is provided on one side of the pushing block 17, and the fixed end of the electric push rod 18 is fixedly connected to the closed end of the loading trough 4; the movable end of the electric push rod 18 is fixedly connected to one side of the pushing block 17.
[0045] In this embodiment, by providing a pusher block 17, the electric push rod 18 is started when pushing the material, and the electric push rod 18 drives the pusher block 17 to push the metal workpiece to move.

[0048] In this embodiment, by providing the weight block 20, the metal workpiece has a larger gravity, which prevents the entire device from moving in the opposite direction of the pushing direction when the metal workpiece is pushed, thereby improving the stability of the device.
[0049] The following is a detailed description of the working principle of the kiln feeding noise reduction structure.
[0050] like Figure 1-5 As shown, when the metal workpiece is heat treated, the lifting component 3 is started, and the lifting component 3 descends to drive the loading trough 4 to descend, so that the loading trough 4 descends to a height that the staff can operate, and then the staff puts the workpiece into the closed end of the loading trough 4. After the metal workpiece is placed on the loading trough 4, the pushing component 6 is started, and the metal workpiece is pushed to move by the pushing component 6. By setting a plurality of transfer rollers 7, the metal workpiece is placed on the transfer roller 7 when it is placed on the bottom of the loading trough 4. The transfer roller 7 converts the sliding of the metal workpiece in the transmission process into rolling, so that the friction force is greatly reduced, thereby greatly reducing the noise generated by the metal workpiece in the transportation process; when the workpiece reaches the buffer component 5, it first falls into the receiving box 9, and then a loading plate 11 is provided inside the material receiving box 9, and the metal workpiece will fall onto the loading plate 11. When the gravity of the workpiece on the loading plate 11 is greater than the elastic force of the spring 12, the hydraulic oil in the hydraulic cylinder 10 is saved, and the loading plate 11 descends to drive the piston to squeeze the hydraulic oil, thereby causing the lifting rod 14 to rise and then driving the baffle 16 to rise. During the whole process, the metal workpiece is buffered by the piston and the spring 12, so that the metal workpiece falls into the material receiving box 9 and is first buffered so that the metal workpiece can stay in the material receiving box 9, and then enters the kiln through the discharge port, so that the speed of the workpiece entering the kiln is slowed down, the impact is reduced, and the noise is reduced. In addition, the buffer component 5 can also prevent the impact between the metal workpieces from causing damage to the workpiece.
[0051] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
