Description

Technical Field

[0001] This invention relates to the field of chip conveyor technology, and more specifically, to a chip conveyor that is easy to clean. Background Technology

[0002] In the field of modern machining, chip conveyors are key auxiliary equipment in metal cutting processes, and their performance directly affects production efficiency and workshop environmental quality. However, under current technological conditions, chip conveyors face significant functional limitations in practical applications. Specifically, when machine tool chips are compressed or accumulated over a long period, they often form expanded, loosely structured chip clumps. These uniquely shaped chip clumps are difficult to maintain stable friction on the smooth surface of traditionally designed chain plates, leading to frequent slippage, accumulation, and even rolling of the chips during transport. To solve this technical problem, the industry commonly uses vertical or inclined lever structures on the chain plate surface, utilizing the mechanical meshing force between the levers and the chip clumps to improve the conveying effect. This design has indeed improved the chip conveyor's ability to convey expanded chip clumps to a certain extent, enabling even large, irregularly shaped chip clumps to be effectively pushed forward, thus improving the chip conveying system's processing capacity and the reliability of continuous operation.

[0003] However, while the improved design of setting levers on the chain plate solved the conveying efficiency problem, it also caused a series of new usage and maintenance challenges. While enhancing the conveying capacity, the lever structure also created numerous uneven surfaces and hidden spaces. These areas easily accumulate a mixture of fine iron filings, cutting fluid, and metal dust. These residues gradually harden over time, not only reducing the effective height and meshing capacity of the levers but also potentially increasing the running resistance of the chain plate and accelerating equipment wear. More importantly, conventional cleaning methods such as rinsing or scraping are inefficient in the face of this complex structure. Maintenance personnel need to invest a lot of time and effort to complete a thorough cleaning, sometimes even requiring the disassembly of some chain plate components to access deep-seated dirt. This cleaning difficulty not only reduces the daily maintenance efficiency of the equipment and increases downtime and maintenance costs but also easily leads to incomplete cleaning, thereby affecting the long-term operational stability and service life of the equipment. Summary of the Invention

[0004] (a) Technical problems to be solved In view of the problems existing in the prior art, the present invention provides a chip conveyor that is easy to clean, so as to solve the technical problems mentioned in the background art.

[0005] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: a convenient and easy-to-clean chip conveyor, comprising a fixedly installed conveyor frame; further comprising a lifting mechanism, the lifting mechanism comprising multiple hydraulic cylinders fixedly installed on both sides of the conveyor frame, a lifting plate being installed on the extended end of every two hydraulic cylinders, a receiving plate being fixedly installed on the conveyor frame, a steel strip being connected to the upper limit of the receiving plate, the steel strip being attached to the lifting plate, a control tube being fixedly installed on the lifting plate, a top hole being opened on the control tube, a push rod being slidably connected in the top hole, a through hole being opened on the steel strip, the push rod passing through the through hole, and a flow groove being opened on the outer wall of the steel strip; further comprising a tensioning mechanism, the tensioning mechanism comprising multiple fixed wheels and multiple follower wheels clamped onto the steel strip, the multiple fixed wheels and the multiple follower wheels being equally spaced.

[0006] Preferably, the lifting mechanism further includes an oil outlet plate coaxially mounted on the lifting rod. The oil outlet plate is attached to the upper end of the control tube. Multiple vertical grooves are provided on the side wall of the lifting rod. This structural design allows the oil outlet plate to form a reliable sealing contact with the upper end of the control tube. When the lifting rod is subjected to pressure and moves downward, the oil outlet plate will move downward and disengage from the sealing position. The multiple vertical grooves on the side wall of the lifting rod provide a flow channel for lubricating oil, ensuring that the lubricating oil can be effectively released and lubricated to the contact parts, thereby reducing friction and wear.

[0007] Preferably, a positioning rod is coaxially provided on the oil outlet plate, a sealing sleeve is slidably connected inside the control tube, the positioning rod is slidably connected inside the sealing sleeve, and a return spring is sleeved on the positioning rod. One end of the return spring abuts against the oil outlet plate, and the other end of the return spring abuts against the sealing sleeve.

[0008] Preferably, a threaded sleeve is installed at the lower end of the control tube, and a threaded tube is installed inside the threaded sleeve. The threaded tube is connected to the sealing sleeve, and an oil inlet pipe is installed on the side wall of the control tube. The oil inlet pipe is connected to an external oil inlet device. This adjustable threaded connection structure allows the operator to precisely adjust the preload of the return spring by rotating the threaded tube.

[0009] Preferably, two sets of chains are rotatably mounted on the conveyor frame, and multiple chain plates are installed at equal intervals on each of the two sets of chains. Multiple telescopic rods are slidably connected to each chain plate at equal intervals. This dual-chain parallel transmission structure enhances the stability and load-bearing capacity of the conveying system.

[0010] Preferably, a synchronization frame is installed at the lower end of each of the multiple telescopic rods, and side rods are installed on both sides of the synchronization frame. Two side rods are slidably connected to the chain plate. This synchronization frame connection mechanism ensures that multiple telescopic rods can extend or retract simultaneously, avoiding uneven thrust caused by asynchronous movement of a single telescopic rod.

[0011] Preferably, each of the side rods is equipped with a round head, and the round head abuts against the flow groove. A top spring is sleeved on the side rod, one end of the top spring abuts against the chain plate, and the other end of the top spring abuts against the round head. This elastic triggering mechanism allows the round head to slide smoothly in the flow groove and sense the position of the steel strip.

[0012] Preferably, multiple fixed wheels are rotatably connected to a fixed frame, and multiple follower wheels are rotatably connected to a follower frame. Multiple guide rods are installed on the fixed frame, and multiple guide sleeves are installed on the follower frame. The guide rods are slidably connected to the guide sleeves. This guiding sliding mechanism ensures that the movement of the follower frame relative to the fixed frame always remains on a predetermined track.

[0013] Preferably, multiple springs are installed at equal intervals between the fixed frame and the follower frame, and an intermediate plate is installed at the middle position of each spring. This multi-point elastic tensioning structure enables the steel strip to maintain appropriate tension at all times. When the steel strip changes its length requirement due to lifting, the springs will automatically extend and retract to compensate for the length change.

[0014] Preferably, the fixing frame is threaded with multiple adjusting bolts, and a fixing spring is sleeved on the adjusting bolts, with the adjusting bolts abutting against the intermediate plate.

[0015] (III) Beneficial Effects Compared with the prior art, the present invention provides a chip conveyor that is easy to clean and has the following beneficial effects: The innovative technology of this convenient and easy-to-clean chip conveyor lies in its intelligent telescopic pusher structure design. Unlike the fixed lever structure on traditional chip conveyors, this design uses a controllable telescopic pusher mechanism. A hydraulic lifting system enables the automatic extension and retraction of the pusher component. Under normal conveying conditions, when a clump of chips passes by, the lifting mechanism pushes the steel belt upward, causing the telescopic rod on the chain plate to automatically extend and engage inside the clump of chips, generating a pushing force. This design solves the slippage and accumulation problems often encountered by traditional chip conveyors when dealing with expanding clumps of chips, ensuring continuous and stable conveying. When cleaning is required... During maintenance, operators only need to control the hydraulic system to reset the steel belt. All telescopic rods will automatically retract into the chain plate under the action of spring force, restoring the chain plate surface to a flat state. This component storage mechanism eliminates cleaning obstacles on the chain plate surface, simplifies the cleaning process, and improves cleaning efficiency. Maintenance personnel can directly rinse or scrape the flat chain plate surface to easily remove the attached fine iron filings and cutting fluid mixture without additional disassembly steps, greatly reducing maintenance time and labor intensity. This intelligent telescopic pusher structure achieves convenient cleaning while ensuring efficient conveying.

[0016] This design incorporates a lubrication system. A trigger-type oil circuit control mechanism automatically releases an appropriate amount of lubricating oil when the round-headed components on the chain plate slide in contact with the steel belt, reducing friction and wear between moving parts. This intelligent lubrication system is also equipped with an adjustable oil output control device. Operators can easily adjust the elastic balance point by rotating the device according to actual working conditions, thereby controlling the amount of lubricating oil released per cycle. This ensures sufficient lubrication while avoiding waste and secondary pollution caused by excessive oil use. Secondly, the chip conveyor is equipped with a steel belt tensioning mechanism. Through a combination of fixed and follower wheels, combined with a spring buffer system, the tension of the steel belt can be adjusted. When the position of the steel belt changes, the tensioning mechanism automatically compensates for the length change, always maintaining the steel belt at an appropriate tension. This ensures precise control and reliable operation of the lifting system. The combination of these multiple collaborative mechanisms improves the conveying efficiency and cleaning convenience of the chip conveyor, extends the service life of the equipment, and reduces maintenance costs, providing a brand-new solution for chip removal in the metal processing industry.

[0022] Please see Figures 1 to 9A convenient and easy-to-clean chip conveyor includes a fixedly mounted conveyor frame 11 and a lifting mechanism. The lifting mechanism includes multiple hydraulic cylinders 21 fixedly mounted on both sides of the conveyor frame 11. A lifting plate 22 is mounted on the extended end of every two hydraulic cylinders 21. A receiving plate 23 is fixedly mounted on the conveyor frame 11. A steel strip 24 is connected to the upper limit of the receiving plate 23 and adheres to the lifting plate 22. A control pipe 25 is fixedly mounted on the lifting plate 22. A top hole 26 is opened on the control pipe 25, and a top rod 27 is slidably connected in the top hole 26. The 4-strip has a through hole 28 through which the push rod 27 passes. A flow groove 29 is formed on the outer wall of the steel strip 24. The lifting mechanism also includes an oil outlet plate 210 coaxially mounted on the push rod 27. The oil outlet plate 210 fits against the upper end of the control tube 25. Multiple vertical grooves 211 are formed on the side wall of the push rod 27. A positioning rod 212 is coaxially mounted on the oil outlet plate 210. A sealing sleeve 213 is slidably connected inside the control tube 25. The positioning rod 212 is slidably connected inside the sealing sleeve 213. A return spring 214 is sleeved on the positioning rod 212. One end of the return spring 214 abuts against the oil outlet plate 210, and the other end of the return spring 214 abuts against the sealing sleeve 213. A threaded sleeve 215 is installed at the lower end of the control pipe 25, and a threaded tube 216 is installed in the internal thread of the threaded sleeve 215. The threaded tube 216 is connected to the sealing sleeve 213. An oil inlet pipe 217 is installed on the side wall of the control pipe 25 and is connected to an external oil inlet device. Two sets of chains 218 are rotatably installed on the conveyor frame 11, and multiple chain plates 219 are installed at equal intervals on the two sets of chains 218. Each chain plate 219... Multiple telescopic rods 220 are slidably connected at equal intervals on the chain plate 219. A timing frame 221 is installed at the lower end of each telescopic rod 220. Side rods 222 are installed on both sides of the timing frame 221. The two side rods 222 are slidably connected to the chain plate 219. A round head 223 is installed on each side rod 222, and the round head 223 abuts against the flow groove 29. A top spring 224 is sleeved on the side rod 222. One end of the top spring 224 abuts against the chain plate 219, and the other end of the top spring 224 abuts against the round head 223.

[0023] During the conveying of iron filings, the rotation of chain 218 drives the rotation of multiple chain plates 219. Under the action of top spring 224, when the round head 223 is not in contact with the steel belt 24, multiple telescopic rods 220 retract into the chain plates 219. When the hydraulic cylinder 21 drives the lifting plate 22 to move upward, it pushes the steel belt 24 upward. When the chain plate 219 drives the round head 223 to the position of the lifted steel belt 24, it will push the synchronous frame 221 to drive the multiple telescopic rods 220 upward. The multiple telescopic rods 220 extend out of the chain plate 219 and insert into the metal scrap clump, thus increasing the force pushing the metal scrap clump to move and ensuring that slippage does not occur. When cleaning is required after conveying, simply move the hydraulic cylinder 21 downward to reset the steel belt 24. Under the action of the top spring 224, the telescopic rods 220 will retract back into the chain plate 219, thus avoiding the impact of the multiple telescopic rods 220 on the cleaning of the chain plate 219 and improving the convenience of cleaning.

[0024] As the hydraulic cylinder 21 drives the lifting plate 22 upward, the steel belt 24, whose upper middle position is fixedly connected to the middle position of the lifting plate 22, will not change its position relative to the lifting plate 22. Then, as it moves upward, the chain 218 drives multiple chain plates 219 to move cyclically, and the round head 223 will press against the flow groove 29. As the round head 223 continues to move, when it moves along the flow groove to the push rod 27, it will press down on the push rod 27, thereby releasing the seal between the oil pan 210 and the control pipe 25. Since the oil inlet pipe 217 is connected to the outside... On the oiling equipment, a little lubricating oil will flow out, thereby reducing the friction of the round head 223 sliding along the flow groove 29, thus improving the ease of sliding. When it is necessary to adjust the opening degree of the push rod 27, since the threaded tube 216 is threadedly connected to the threaded sleeve 215, the compression of the return spring 214 can be changed by rotating the threaded tube 216, thereby changing the elastic force on the push rod 27. Since the round head 223 is also subject to the elastic force of the push spring 224, when the elastic force of the return spring 214 increases, the opening degree of the return spring 214 decreases, thus reducing the amount of oil dispensed at one time, so as to adapt to the corresponding situation.

[0025] The tensioning mechanism includes multiple fixed wheels 31 and multiple follower wheels 32 that are engaged on the steel belt 24. The fixed wheels 31 and the follower wheels 32 are equally spaced. The fixed wheels 31 are rotatably connected to the fixed frame 33, and the follower wheels 32 are rotatably connected to the follower frame 34. Multiple guide rods 35 are installed on the fixed frame 33, and multiple guide sleeves 36 are installed on the follower frame 34. The guide rods 35 are slidably connected to the guide sleeves 36. Multiple springs 37 are equally spaced between the fixed frame 33 and the follower frame 34, and an intermediate plate 38 is installed at the middle position of each spring 37. Multiple adjusting bolts 39 are threadedly connected to the fixed frame 33. Fixed springs 310 are sleeved on the adjusting bolts 39, and the adjusting bolts 39 abut against the intermediate plate 38.

[0026] When the hydraulic cylinder 21 drives the steel belt 24 to move upward, since the middle position of the steel belt 24 is fixedly connected to the lifting plate 22, the upper middle position of the steel belt 24 will not move, thereby driving the steel belts 24 on both sides to move. At this time, since the steel belt 24 is respectively engaged with multiple fixed wheels 31 and follower wheels 32, and the fixed wheels 31 are rotatably connected to the fixed frame 33, and the follower wheels 32 are rotatably connected to the follower frame 34, the two are positioned by the guide rod 35 and the guide sleeve 36. At this time, the spring 37 will be compressed, thus reducing the distance between the fixed frame 33 and the follower frame 34, thereby adjusting the length of the upper steel belt 24. When it is necessary to adjust the elastic force of the spring 37 to extend and retract by the same displacement, the adjusting bolt 39 is rotated so that the adjusting bolt 39 is pressed against the middle plate 38, and then the spring 37 is pushed, thereby changing the elastic force generated by the spring 37 at the same position, thereby increasing the tension of the steel belt 24.

[0027] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. 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 variations can be made to these embodiments without departing from the principles and spirit of the present invention.
