Description

Technical Field

[0001] The present invention relates to the technical field of chip conveyors, and more particularly to a chip conveyor with a lubricating mechanism. Background Art

[0002] In the field of contemporary mechanical processing and metal manufacturing, the efficient processing and transportation of iron chips is a key link to ensure production continuity and environmental safety. The current technical route generally adopts a processing mode of compression before transportation. This is mainly because the newly generated iron chips are usually fluffy, large in volume and low in density. Direct transportation not only wastes space but also reduces efficiency. Traditional compression devices mostly adopt a design scheme of fixedly installing transverse rods on the surface of the conveyor roller. These transverse rods can be inserted into the fluffy iron chips during rotation, and use mechanical force to capture and compress them into a tighter form. However, this fixed transverse rod design has serious technical blind spots and cannot intelligently adjust the working state according to the different stages of the compression cycle. Since the compression process is cyclical, the transverse rods can only truly exert the compression function in specific areas where the conveyor rollers are close to each other. In most of the other rotation cycles, these transverse rods that are always exposed not only have no substantial effect, but will continue to stir the compressed iron chips, interfering with the normal conveying process.

[0003] The contradiction between the rigidity of this design and the flexibility of process requirements has directly led to a series of serious operational problems and efficiency losses. The most prominent is the phenomenon of over-entanglement. Those unnecessarily exposed transverse rods will continuously capture and entangle the compressed iron chips during rotation, causing the material that should have been conveyed smoothly to be repeatedly lifted and lowered, which not only disrupts the material flow path, but also causes the iron chips to accumulate on the conveyor rollers to form larger and larger entanglements. This unexpected entanglement will significantly increase the operating load of the conveying system, accelerate equipment wear, shorten the maintenance cycle, and even cause motor overload or transmission system failure in severe cases. From the perspective of production efficiency, this entanglement phenomenon will reduce the actual processing rate of iron chips, increase the frequency and difficulty of manual cleaning, and cause unnecessary downtime and labor costs. In addition, the over-entangled iron chips may block the conveying channel or damage subsequent processing equipment when they fall off, posing a safety hazard. Summary of the Invention

[0004] (1) Technical problems solved In view of the problems existing in the prior art, the present invention provides a chip conveyor with a lubrication mechanism to solve the technical problems mentioned in the background technology.

[0005] (2) Technical solution To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a chip conveyor with a lubrication mechanism, comprising a feed hopper and a fixed frame, the feed hopper being mounted on the fixed frame; further comprising a telescopic mechanism, the telescopic mechanism comprising two unidirectional rollers rotatably connected to the feed hopper, the unidirectional rollers being provided with a plurality of telescopic holes and a plurality of side holes at equal intervals, each of the telescopic holes being slidably connected to a shift rod, a lateral rod being slidably connected in the lateral hole, the lateral rod being provided with a plurality of push grooves corresponding to the shift rod, the shift rod being in contact with the push groove, a tension spring being installed on the shift rod, a limiting groove being provided on the lateral hole, a limiting strip being installed on the lateral rod, the limiting strip being slidably connected in the limiting groove, and a plurality of the tension springs being respectively connected in the limiting groove; further comprising a lubrication mechanism, the lubrication mechanism comprising an oil inlet hole provided on the unidirectional rollers.

[0006] Preferably, the telescopic mechanism also includes two rotating shafts rotatably mounted on the feed hopper, and guide plates are respectively mounted on the two rotating shafts, and multiple lateral rods respectively abut against the guide plates. This combined design of the rotating shaft and the guide plate creates motion control, so that the lateral rod can move according to a preset trajectory. The rotating shaft provides a stable rotation fulcrum to ensure smooth movement of the guide plate, and the carefully designed contour of the guide plate determines the timing and stroke of the telescopic rod.

[0007] Preferably, a synchronous frame is slidably connected to the feed hopper, a screw is threadedly connected to the feed hopper, the screw abuts against the synchronous frame, a follower rod is installed on the side where the two guide plates are close to each other, and the synchronous frame abuts against the two follower rods. This synchronous adjustment mechanism provides the equipment with flexible parameter adjustment capabilities.

[0008] Preferably, a reducer is mounted on the fixing frame, a motor is mounted on the reducer, a conveyor belt is rotatably mounted on the fixing frame, and the protruding end of the reducer is connected to the conveyor belt.

[0009] Preferably, a synchronous wheel is installed on the protruding end of the reducer, a transmission rod is rotatably installed on the fixed frame, the transmission rod is connected to the co-directional roller, a synchronous wheel is installed on the transmission rod, and a conveyor belt is installed between the two synchronous wheels.

[0010] Preferably, transmission wheels are respectively mounted on the two co-directional rollers, and the transmission wheels are meshed with each other.

[0011] Preferably, the lubrication mechanism includes a filler pipe threadedly connected to the oil inlet hole, a plurality of through holes are opened in the oil inlet hole, and the plurality of through holes are respectively connected to the limit grooves. This distributed lubrication channel design forms a lubricant delivery mechanism. The threaded connection mode of the filler pipe facilitates installation and disassembly, making lubricant addition and system maintenance simple and quick. The oil inlet hole serves as the main channel and the plurality of through holes serve as branches, together forming a tree-like distribution structure, ensuring that the lubricant can be evenly distributed to each limit groove and ultimately reach the active part of each lever.

[0012] Preferably, a sealing head is provided in a sealing sliding connection in the refueling pipe, a spring is installed on the sealing head, a sealing rod is installed at the other end of the spring, and the sealing rod is threadedly connected to the refueling pipe. This elastic pressure lubrication system creates an adaptive lubricant supply mechanism.

[0013] Preferably, each of the levers is provided with an oil outlet hole, and when the tension spring is in a state of no stress, the oil outlet hole is sealed and connected to the telescopic hole. This intelligent switch-type lubrication design realizes the precise delivery of lubricant on demand, and the sealed connection between the oil outlet hole and the telescopic hole forms an automatic control valve. The lubrication channel is opened only when the lever is extended to the working state, ensuring that the lubricant is released only at the critical moment when the lever contacts the iron chips, avoiding unnecessary lubrication and waste of lubricant in non-working areas.

[0014] Preferably, a plurality of the levers are respectively provided with round heads. Such round head design provides optimized mechanical properties and protection functions for the contact interface between the lever and the iron chips. The circular profile eliminates sharp edges and corners, significantly reducing the risk of cutting and damaging the iron chips.

[0015] (3) Beneficial effects Compared with the prior art, the present invention provides a chip conveyor with a lubrication mechanism, which has the following beneficial effects: The chip conveyor adopts telescopic compression technology, which solves the problem of excessive winding of iron chips caused by the fixed cross bar in traditional chip conveying equipment. Unlike traditional equipment, the lever of this equipment can automatically extend and retract according to the working cycle, and only extends to work in the compression area where the rollers in the same direction are close to each other, and automatically retracts in the rest of the non-working area. This dynamic adjustment capability ensures that the lever only works in the area where compression is really needed, avoiding the problem of repeated winding of iron chips caused by the continuous exposure of the cross bar throughout the rotation cycle in traditional equipment. The design realizes the control of the lever through a mechanical linkage system. The guide plate, lateral rod, push groove and tension spring and other components form a complete motion transmission chain, which enables the lever to be in a specific position. The lever automatically extends out of the right position and quickly retracts after leaving the compression area. This telescopic function not only greatly reduces the risk of iron chips entanglement, but also improves the operating stability and life of the equipment. The design of the synchronous frame and screw allows the operator to adjust the timing and range of the extension of the lever according to the characteristics of different types of iron chips, thereby enhancing the adaptability of the equipment. In addition, the coordinated work of the reducer, motor and transmission system ensures the smooth and efficient operation of the entire compression and conveying process. The engagement of the transmission wheel ensures the synchronous operation of the two coinciding rollers, creating conditions for the uniform compression of the iron chips. This innovative design significantly improves the efficiency of iron chip processing, reduces equipment failure rate and maintenance frequency, and brings economic benefits to metal processing companies.

[0016] Another innovation of this chip conveyor is its intelligent directional lubrication system, which realizes the precise supply of lubricant at the time and place where it is most needed. The lubrication system is designed with oil inlet, through hole and oil outlet holes, so that the lubricating oil is released only when the lever is extended in the working state, ensuring the delivery of lubricant. When the lever is extended in the compression area, the seal between the oil outlet hole and the telescopic hole is automatically released, allowing the lubricating oil to flow out from the end of the lever to directly lubricate the key parts that contact the iron chips. This directional lubrication technology brings multiple technical advantages. First, the presence of lubricant reduces the friction between the lever and the iron chips, reducing the mechanical resistance during the compression process. Second, proper lubrication effectively reduces the sharp friction sound between metals, improves the noise level of the working environment, and improves the operating comfort.

[0017] The spring applies continuous and stable pressure to the sealing head, ensuring that lubricating oil can be output at the appropriate pressure when needed, regardless of the equipment's operating posture or changes in oil volume. In addition, the round-headed lever design not only improves the lubrication effect, but also reduces the cutting and damage to iron chips, ensuring the quality of the iron chips and facilitating their subsequent recycling. This automatic directional lubrication system transforms equipment maintenance from passive repair to active prevention, reducing failure rates and unplanned downtime, and improving the overall reliability and economic benefits of the production line.

[0023] See also Figures 1 to 8A chip conveyor with a lubricating mechanism includes a feed hopper 11 and a fixed frame 12, the feed hopper 11 is mounted on the fixed frame 12; the telescopic mechanism includes two unidirectional rollers 21 rotatably connected to the feed hopper 11, and the unidirectional rollers 21 are provided with a plurality of telescopic holes 22 and a plurality of lateral holes 23 at equal intervals. A lever 24 is slidably connected to each telescopic hole 22, and a lateral rod 25 is slidably connected to the lateral hole 23. The lateral rod 25 is provided with a plurality of and The push groove 26 corresponding to the lever 24 is in contact with the lever 24, and a tension spring 27 is installed on the lever 24. A limit groove 28 is provided on the lateral hole 23, and a limit strip 29 is installed on the lateral rod 25. The limit strip 29 is slidably connected in the limit groove 28, and multiple tension springs 27 are respectively connected in the limit groove 28. The telescopic mechanism also includes two rotating shafts 210 rotatably mounted on the feed hopper 11, and guide plates 211 are respectively installed on the two rotating shafts 210. Multiple lateral rods 25 respectively abut on the guide plate 211, the feed hopper 11 is slidably connected to a synchronous frame 212, the feed hopper 11 is threadedly connected to a screw 213, the screw 213 abuts on the synchronous frame 212, the two guide plates 211 are installed on the side close to each other with a follower rod 214, the synchronous frame 212 abuts on the two follower rods 214, the fixed frame 12 is installed with a reducer 215, the reducer 215 is equipped with a motor 216, and the fixed frame 12 is rotatably installed. There is a conveyor belt 217, the protruding end of the reducer 215 is cooperatively connected to the conveyor belt 217, a synchronous wheel 218 is installed on the protruding end of the reducer 215, a transmission rod 219 is rotatably installed on the fixed frame 12, the transmission rod 219 is connected to the same-direction roller 21, and a synchronous wheel 218 is installed on the transmission rod 219. A conveyor belt 220 is installed between the two synchronous wheels 218, and transmission wheels 221 are respectively installed on the two same-direction rollers 21, and the transmission wheels 221 are meshed with each other.

[0024] When conveying iron chips, the iron chips will first enter the feed hopper 11, and the motor 216 and the reducer 215 can drive the rotation of the conveyor belt 220 and the rotation of the transmission rod 219, and the engagement between the two transmission wheels 221 ensures the same-direction rotation of the two rollers 21, which will drive the screw 213 to rotate, thereby pushing the synchronous frame 212 to press against the two follower rods 214, and then drive the two guide plates 211 to rotate along the rotating shaft 210 respectively, and the lateral rods 25 on one side of the two follower rods 214 will be pushed, so that the lateral rods 25 are pushed inward along the lateral holes 23, and the push grooves 26 are pushed, so that the lever 24 on the same side as the lateral rod 25 is pushed upward, so that the two The lever 24 on the side where the same-direction rollers 21 are in contact with each other will extend outward. When the iron filings enter the feed hopper 11, the lever 24 on the side close to the same-direction rollers 21 will be inserted into the iron filings. Then, as the same-direction rollers 21 rotate, the iron filings are pushed downward to be compressed. When they are away from the side where the two same-direction rollers 21 are close to each other, the extension of the guide plate 211 becomes smaller, so the lateral rod 25 will rebound and shrink inward under the action of the tension spring 27. Therefore, only the lever 24 on the side close to each other will play a corresponding pushing role, and the area out of contact will be retracted into the telescopic hole 22, avoiding the iron filings from being entangled on the lever 24, reducing the impact on the iron filings, and the compressed iron filings will be discharged along with the conveyor belt 220, thereby completing the chip removal process.

[0025] The lubrication mechanism includes an oil inlet hole 31 provided on the co-directional roller 21, and the lubrication mechanism includes a refueling pipe 32 threadedly connected to the oil inlet hole 31. A plurality of through holes 33 are provided in the oil inlet hole 31, and the plurality of through holes 33 are respectively connected to the limit groove 28. A sealing head 34 is sealingly and slidingly connected in the refueling pipe 32, and a spring 35 is installed on the sealing head 34. A sealing rod 36 is installed at the other end of the spring 35, and the sealing rod 36 is threadedly connected to the refueling pipe 32. An oil outlet hole 37 is respectively provided on each shift rod 24. When the tension spring 27 is in a non-stressed state, the oil outlet hole 37 is sealed and connected to the telescopic hole 22. A round head 38 is respectively provided on the plurality of shift rods 24.

[0026] As the multiple levers 24 move to an area close to each other, they will be pushed out, and the oil outlet hole 37 will leave the seal between it and the telescopic hole 22. At this time, the pressurized lubricating oil in the oil inlet hole 31 will enter the lower ends of the multiple levers 24 through the through hole 33, and then the lubricating oil will be discharged through the oil outlet hole 37. Since only in the compression stage of approaching each other will a large force be compressed, lubrication can not only reduce the friction of the multiple levers 24 but also reduce the sharp friction sound generated between the iron filings and the lever 24 when the compression is performed, thereby improving the conveying effect. Since the oil outlet hole 37 will be unsealed only when the levers 24 are rotated to an area close to each other, lubrication will be carried out in a targeted manner to ensure the use effect. The oil inlet hole 31 is internally threaded with a refueling pipe 32, and a spring 35 is used to apply elastic force to the sealing head 34, and the sealing head 34 applies pressure to the internal lubricating oil. When the oil outlet hole 37 is unsealed, the thrust of the spring 35 applies corresponding pressure, thereby ensuring the continuity of lubrication.
