Description

Technical Field

[0001] This application relates to the field of cutting machine technology, and in particular to an automatic waste discharge device for a cutting machine. Background Technology

[0002] During the operation of two-dimensional cutting machines (such as laser cutting machines and plasma cutting machines), the waste generated during cutting falls from the waste outlet at the bottom of the worktable to the area below the equipment due to gravity. Traditional physical cleaning methods require operators to disconnect the power supply to the equipment and manually enter the space under the equipment to use tools for cleaning. This cleaning process requires the equipment to be stopped, and the dust particles accumulated during the cleaning process are directly diffused into the surrounding space.

[0003] To replace manual cleaning processes, existing technologies (such as Chinese Utility Model Patent Publication No. CN222492645U) disclose an automatic material unloading device for laser cutting machines. This technical solution uses a horizontal conveyor belt installed directly below the cutting platform to catch and physically transport the falling waste material. However, this existing device has limitations in its physical structure during actual mechanical operation. The transmission structure of this conveyor device uses gears meshing with gear holes on the surface of the belt to transmit torque. Since the gear holes are directly exposed on the upper surface of the belt, fine metal fragments and dust generated during cutting can easily enter and fill the internal space of the gear holes when they fall, thus physically blocking the meshing path of the gear teeth into the belt holes, causing mechanical jamming and interruption of the transmission mechanism. At the same time, this device uses a non-metallic belt as the contact surface for carrying waste material. The metal waste that falls off during cutting carries a high residual heat. Direct contact between the high-temperature waste and the belt can cause the belt material to melt or deform due to heat, damaging the physical structural strength of the bearing surface. Furthermore, the transmission and conveying frame of the device only supports a single conveyor belt to discharge waste from the central axis of the equipment. It lacks a mechanical parallel extension structure to add execution units to both sides. Its physical receiving area cannot cover the multi-waste cutting machine with a large lateral span, causing waste in non-central areas to fall directly to the ground. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic waste discharge device for cutting machines, which solves the problems in existing automatic waste discharge devices for cutting machines, such as the transmission mechanism being easily blocked and jammed by falling dust, the conveyor belt bearing surface being easily damaged by high-temperature metal waste, and the single-line conveyor structure being unable to physically cover multiple material dropping areas at the bottom of wide equipment.

[0005] This invention provides the following solution:

[0006] According to the present invention, an automatic waste discharge device for a cutting machine is provided, comprising a motor fixing support, a fixed sprocket assembly support, and a waste discharge support; a drive mechanism is fixed on the motor fixing support, a first transmission chain is connected to the drive mechanism, the other end of the first transmission chain is connected to a fixed sprocket assembly installed on the fixed sprocket assembly support and the waste discharge support, a driven sprocket assembly is installed on the waste discharge support, a second transmission chain is connected between the fixed sprocket assembly and the driven sprocket assembly, a plurality of wear-resistant plates covering the entire transmission chain are fixed on the second transmission chain, and a waste bin is placed separately at the end of the automatic waste discharge device.

[0007] Preferably, the motor of the drive mechanism is connected to a reducer via a coupling, and a sprocket connected to the transmission chain is mounted on the reducer;

[0008] The motor and reducer are bolted to the tension support, which has an elongated mounting hole and is fixed to the motor mounting support.

[0009] Preferably, the driving sprocket of the fixed sprocket assembly is fixed on the driving shaft, and the driving sprocket is connected to the first transmission chain; the driving shaft and the driven shaft are connected by a coupling, and a second sprocket is mounted on the driven shaft, and the second sprocket is connected to the second transmission chain;

[0010] The drive shaft and driven shaft are fixed to the working plane by a fixed bearing support, and the coupling, sprocket two and fixed bearing support are fixed together by a shaft sleeve one and a shaft shoulder structure.

[0011] Preferably, the sprocket three of the driven sprocket assembly is fixed to the shaft by the bushing two, and the sprocket three is connected to the transmission chain two;

[0012] The shaft has milled flat positions at both ends and is placed on tension support two. Adjusting bolts are installed on tension support two and are connected to the milled flat positions of the shaft.

[0013] Preferably, the sprockets on the second transmission chain, the fixed sprocket group, and the driven sprocket group are all located inside the waste material handling mechanism composed of the wear-resistant plates.

[0014] Preferably, the fixed sprocket support, waste discharge support, transmission chain two, driven sprocket group and wear-resistant plate form a waste collection workbench, and the sprocket two on each driven shaft is connected to a set of the waste collection workbench.

[0015] Preferably, the motor fixing support, the fixed sprocket assembly support, and the waste discharge support are all fixedly connected using an anchor bolt structure.

[0016] Preferably, the waste collection workbench is equipped with a protective plate on its side.

[0017] Preferably, the waste collection workbench has a longitudinal inclination, and the wear-resistant plate is made magnetic;

[0018] The waste bin is equipped with wheels and a motor drive mechanism.

[0019] Preferably, a scraper mechanism is added at the waste discharge position at the end of the automatic waste discharge device line.

[0020] The above solution achieves the following beneficial technical effects:

[0021] This invention uses a drive mechanism to drive a transmission chain two covered with wear-resistant plates in a unidirectional cyclic motion, which horizontally conveys the waste material that slides from the waste outlet of the cutting machine onto the surface of the wear-resistant plates towards the tail of the line. The waste material then falls into an independent waste bin at the driven sprocket assembly as the wear-resistant plates turn. This structure uses continuous mechanical conveying to replace the step of manually entering under the workbench to clean the waste material, realizing the automatic collection and centralized temporary storage of waste material and eliminating the need for manual shutdown to clean the waste material.

[0022] In this invention, the sprockets of the second transmission chain, the fixed sprocket group, and the driven sprocket group are all positioned directly below the receiving plane formed by splicing multiple wear-resistant plates. This arrangement allows the wear-resistant plates to form a physical isolation layer in the vertical direction while bearing the waste material, directly blocking the path of metal slag and dust generated during cutting into the meshing gap between the lower sprocket and the chain teeth. This prevents mechanical blockage and operational stagnation in the transmission mechanism caused by foreign objects getting stuck or dust accumulation.

[0023] The waste receiving surface of this invention is composed of multiple steel wear-resistant plates fixed to the outer side of the transmission chain. Utilizing the mechanical strength and high-temperature resistance of the steel wear-resistant plates, this receiving surface can directly withstand the mechanical impact force of the falling metal waste generated during cutting, as well as the residual heat carried by the waste. This prevents the bottom transmission chain from deforming due to direct impact from heavy objects, or from suffering heat annealing damage due to direct contact with high-temperature waste.

[0029] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] See attached document Figures 1-4 This invention provides an automatic waste discharge device for a cutting machine, including a motor fixing support 15, a fixed sprocket assembly support 4, and a waste discharge support 8; a drive mechanism 1 is fixed on the motor fixing support 15, a transmission chain 2 is connected to the drive mechanism 1, the other end of the transmission chain 2 is connected to a fixed sprocket assembly 3 installed on the fixed sprocket assembly support 4 and the waste discharge support 8, a driven sprocket assembly 9 is installed on the waste discharge support 8, a transmission chain 7 is connected between the fixed sprocket assembly 3 and the driven sprocket assembly 9, a plurality of wear-resistant plates 5 covering the entire transmission chain are fixed on the transmission chain 7, and a waste bin 10 is placed separately at the end of the automatic waste discharge device.

[0031] Specifically, in terms of physical spatial layout, the automatic waste discharge device is placed entirely below the cutting machine's workbench, with its vertical projection covering the lower opening of the cutting machine's funnel-shaped waste discharge port. The motor fixed support 15, the fixed sprocket set support 4, and the waste discharge support 8 are fixed in a straight array on the horizontal ground, forming the basic support frame. During operation, the waste generated by cutting falls vertically through the gaps in the workbench grid under the action of gravity onto the upper surface of the wear-resistant plate 5. The drive mechanism 1 outputs rotational power, which drives the fixed sprocket set 3 to rotate through the transmission chain 2, thereby driving the transmission chain 7, which is sleeved between the fixed sprocket set 3 and the driven sprocket set 9, to perform unidirectional cyclic motion. The continuous receiving plane formed by splicing multiple wear-resistant plates 5 moves synchronously with the transmission chain 7, continuously conveying the waste material carried from directly below the waste inlet to the end of the waste discharge support 8. When the wear-resistant plate 5 passes around the driven sprocket group 9 and flips downward, the waste material loses its bottom support and falls vertically into the waste box 10 located directly below it under the action of gravity. This physical conveying process replaces the manual operation of digging out the waste material from the bottom of the equipment, transforming the waste cleaning process into continuous mechanical discharge.

[0032] The motor 11 of the drive mechanism 1 is connected to the reducer 12 via a coupling. The reducer 12 is equipped with a sprocket 13 connected to the transmission chain 2. The motor 11 and the reducer 12 are bolted to the tension support 14. The tension support 14 has an elongated hole for mounting. The tension support 14 is bolted to the motor mounting support 15.

[0033] Specifically, at the power input end, the output shaft of the motor 11 is rigidly connected to the input end of the reducer 12 via a coupling. The output shaft end of the reducer 12 is keyed to a sprocket 13. The motor 11 and the reducer 12 are fastened as a whole to the top surface of the tension support 14 by bolts. The bottom plate of the tension support 14 has an elongated oval mounting hole along the transmission direction of the transmission chain 2. When it is necessary to restore the meshing clearance of the transmission chain 2, the fastening bolts passing through the elongated oval mounting hole are loosened, and the tension support 14, together with the motor 11 and the reducer 12, is pushed to move linearly along the long axis of the elongated oval hole, thereby changing the center distance between the sprocket 13 and the driving sprocket 35 of the fixed sprocket group 3. After the transmission chain 2 returns to a straight state, the bolts are tightened again to lock the position of the tension support 14.

[0034] The driving sprocket 35 of the fixed sprocket assembly 3 is fixed on the driving shaft 36 and is connected to the first transmission chain 2. The driving shaft 36 and the driven shaft 37 are connected by a coupling 34. A second sprocket 32 ​​is installed on the driven shaft 37 and is connected to the second transmission chain 7. The driving shaft 36 and the driven shaft 37 are fixed to the working plane by a fixed bearing support 31. The coupling 34, the second sprocket 32 ​​and the fixed bearing support 31 are fixed by a structure of a bushing 33 and a shoulder.

[0035] Specifically, the drive shaft 36 and driven shaft 37 are arranged in a straight line on the same horizontal axis. After the drive sprocket 35 obtains the torque of the transmission chain 2, it drives the drive shaft 36 to rotate. The end of the drive shaft 36 is inserted into one end of the coupling 34, and the end of the driven shaft 37 is inserted into the other end of the coupling 34. The rotational torque is transmitted to the driven shaft 37 through the coupling 34, which drives the sprocket 32 ​​on the driven shaft 37 to rotate synchronously. Both the drive shaft 36 and the driven shaft 37 pass through the inner ring of the fixed bearing support 31. The base of the fixed bearing support 31 is fixed to the working plane with bolts. In terms of the longitudinal physical limitation of the shaft, the bushing 33 is sleeved on the shaft surface, so that the end face of the coupling 34, the end face of the sprocket 32, the end face of the fixed bearing support 31, and the end face of the shaft shoulder machined by the shaft itself abut against each other to form a continuous rigid support. This physically blocks the possibility of the rotating parts sliding in the axial direction, and keeps the running trajectory of the transmission chain 7 within the set vertical plane.

[0036] The sprocket 82 of the driven sprocket assembly 9 is fixed on the shaft 83 by the bushing 84. The sprocket 82 is connected to the transmission chain 7. The two ends of the shaft 83 have milled flat positions and are placed on the tension support 81. The tension support 81 is equipped with adjusting bolts 85, which are connected to the milled flat positions of the shaft 83.

[0037] Specifically, sprocket 3 82 is fixed to the middle section of shaft 83 via bushing 2 84. The left and right ends of shaft 83 are machined to form parallel milled flat positions. Tensioner 2 81 has a horizontally extending groove inside. The milled flat position of shaft 83 is engaged in the groove, restricting the rotation of shaft 83 but allowing it to move linearly along the groove. Adjusting bolt 85 is threaded onto the side wall of tensioner 2 81, with its screw end abutting against the side of the milled flat position of shaft 83. When adjusting bolt 85 is turned clockwise with a tool, the bolt is pushed inward along the threaded hole, applying mechanical thrust to shaft 83. This forces shaft 83 and sprocket 3 82 to translate away from the fixed sprocket group 3, thereby increasing the center distance between the sprockets at both ends of transmission chain 2 7 and eliminating physical slack in the chain.

[0038] The sprockets on the fixed sprocket group 3 and the driven sprocket group 9 of the transmission chain 2 7 are all inside the waste material mechanism composed of wear-resistant plates 5.

[0039] Specifically, in the assembled state, the sides of multiple wear-resistant plates 5 are spliced ​​together or adjacent with a very small gap, forming a continuous and flat horizontal shielding surface. The physical installation elevation of the sprocket 2 32 on the fixed sprocket group 3, the sprocket 3 82 on the driven sprocket group 9, and the transmission chain 2 7 sleeved between them are all lower than the bottom surface of the horizontal shielding surface, and their vertical projections are completely within the coverage area of ​​the horizontal shielding surface. When cutting waste and dust fall from above, the upper surface of the wear-resistant plate 5 becomes the first contact surface, directly bearing the falling objects, thereby blocking the physical path of the falling objects into the meshing area between the transmission chain link and the sprocket teeth in three-dimensional space.

[0040] Furthermore, the wear-resistant plate 5 body adopts a wear-resistant steel plate structure with specified mechanical strength and thermal stability. In the physical process of receiving cutting waste, the receiving surface formed by the wear-resistant steel plate serves as the first force-bearing surface, directly absorbing the mechanical impact kinetic energy generated when the waste with gravity falls from the worktable. This prevents the impact force from directly acting on the transmission chain 7 below, causing physical deformation of the chain links. At the same time, the steel material has thermal barrier properties, cutting off the path of the high-temperature residual heat carried by the waste to the moving parts such as the transmission sprocket and bearings below, avoiding the shrinkage of fit tolerance or annealing damage to the moving parts due to thermal expansion.

[0041] The waste collection workbench is composed of the fixed sprocket support 4, the waste discharge support 8, the transmission chain 2 7, the driven sprocket group 9, and the wear-resistant plate 5. The sprocket 2 32 on each driven shaft 37 is connected to a set of waste collection workbenches.

[0042] Specifically, the fixed sprocket support 4, the waste discharge support 8, the second transmission chain 7, the driven sprocket group 9, and the wear-resistant plate 5 covering them are defined as a single waste collection workbench physical unit. In terms of lateral spatial expansion, multiple driven shafts 37 are connected in series along the same center line using the aforementioned coupling 34. The second sprocket 32 ​​installed on each driven shaft 37 meshes with an independent second transmission chain 7. Thus, the rotational torque output by a single drive mechanism 1 is synchronously distributed to multiple driven shafts 37, driving multiple sets of parallel waste collection workbenches to operate simultaneously. The number of driven shafts 37 and waste collection workbenches can be increased or decreased according to the lateral span of the waste outlet of the cutting machine.

[0043] Furthermore, as an alternative physical layout scheme for multi-row waste cutting machine applications: the aforementioned structural design of using coupling 34 to connect multiple driven shafts 37 in series is eliminated. In each independent waste collection workbench unit, an independent drive mechanism 1 and motor fixing support 15 are configured. The independent drive mechanism 1 is connected only to the fixed sprocket group 3 in the workbench through an independent transmission chain 2, realizing the power decoupling of each waste collection workbench. In terms of physical control, the independent operation or stop of a single waste collection workbench can be realized by disconnecting or connecting the power supply circuit of different motors 11. At the same time, in the vertical projection area of ​​the material drop below the waste discharge support 8 of each waste collection workbench, a waste box 10 is placed independently, forming a one-to-one receiving relationship in physical space, preventing the waste discharged from multiple workbench from interfering or accumulating and overflowing in space. The fixed coordinates of the aforementioned independent drive mechanism 1 on the ground can be translated laterally or longitudinally according to the column spacing of the cutting machine or the spatial coordinates of external interference objects, and the length of the transmission chain 2 can be changed to adapt to different power input distances.

[0044] The motor mounting bracket 15, the fixed sprocket assembly bracket 4, and the waste discharge bracket 8 are all fixedly connected using anchor bolts 6.

[0045] Specifically, the base plates of the motor mounting bracket 15, the fixed sprocket assembly bracket 4, and the waste discharge bracket 8 are all provided with through holes. The lower ends of the anchor bolts 6 are pre-embedded or anchored in the concrete ground with load-bearing capacity through an expansion structure. The threaded rods at the upper ends pass through the through holes of each bracket base plate. Adjusting nuts and locking nuts are screwed into the upper and lower sides of the base plate respectively. By rotating the adjusting nuts, the vertical distance of the base plate relative to the ground is changed, and the horizontality of the transmission axis of the entire device is calibrated. After the horizontal calibration is completed, the upper locking nut is tightened so that the base plate is rigidly clamped by the upper and lower nuts, and the three-dimensional coordinates of each bracket relative to the ground are fixed.

[0046] The waste collection workbench is equipped with protective panels on the sides.

[0047] Specifically, rigid protective plates are installed parallel to each other on the left and right sides of the waste collection workbench. The lower part of the protective plate is rigidly fixed to the outer walls of the fixed sprocket support 4 and the waste discharge support 8 by bolt fasteners. The surface of the protective plate extends vertically upward, and the horizontal elevation of its top edge is greater than the horizontal elevation of the receiving plane formed by splicing wear-resistant plates 5. In three-dimensional spatial layout, the inner walls of the vertical protective plates on both sides and the bottom horizontal receiving plane together form a physical constraint channel with a U-shaped cross-section. When the cutting waste or dust falling onto the surface of the wear-resistant plate 5 moves towards the tail of the line, if it produces a lateral displacement perpendicular to the running direction of the transmission chain 7, its edge will directly abut against the inner wall of the protective plate. The protective plate applies a lateral physical reaction force to the waste, blocking the mechanical path of the waste sliding into the external space on both sides of the waste collection workbench, strictly limiting the movement trajectory of the waste within the width range of the wear-resistant plate 5, and forcing the waste to move only in one direction along the conveying axis.

[0048] The waste collection workbench has a longitudinal slope, and the wear-resistant plate 5 is made magnetic; the waste bin 10 is equipped with wheels and a motor drive mechanism.

[0049] Specifically, by setting the installation height of the waste discharge support 8 near one end of the waste bin 10 to be lower than the installation height of the fixed sprocket support 4, the overall receiving plane of the waste collection workbench is made to have a physical downward tilt angle, i.e., a longitudinal slope, towards the material dropping end in the horizontal direction. At the same time, a wear-resistant plate 5 is made of a material with magnetic adsorption capabilities. Ferromagnetic waste falling onto the surface of the wear-resistant plate 5 is attracted to the plate surface by magnetic force, preventing it from sliding downward due to gravity or rolling backward due to mechanical vibration during the inclined conveying process. In addition, rolling wheels are installed on the bottom frame of the waste bin 10, and a motor drive mechanism connected to the wheel drive is installed on the side or bottom of the bin. When the waste bin 10 carries waste to the set weight, the motor drive mechanism outputs torque to drive the wheels to rotate, overcome the ground friction, and move the waste bin 10 horizontally out of the ground from below the waste discharge support 8.

[0050] A scraper mechanism is added at the waste discharge point of the automatic waste discharge device line.

[0051] Specifically, the scraper mechanism is fixedly installed at the end of the waste discharge support 8, with its spatial position directly facing the upper opening of the waste bin 10. The scraper mechanism includes a rigid scraper with a straight cutting edge. The surface of the rigid scraper faces the driven sprocket group 9 at an acute angle. The straight cutting edge of the scraper forms a mechanical contact with or sets a very small gap with the outer surface of the wear-resistant plate 5 that passes around the driven sprocket group 9 and is in the downward flipping stroke. When the wear-resistant plate 5 moves continuously with the chain past the cutting edge position, the scraper cutting edge applies a reverse shearing cutting force to the waste residue adhered to the plate surface, destroying the bonding surface between the waste residue and the wear-resistant plate 5, forcing the waste residue to be mechanically peeled off from the plate surface and fall into the waste bin 10 under the action of gravity.

[0052] Working principle: First, in the initial stage of operation, the motor 11 in the drive mechanism 1 is energized and runs. The output torque of the motor 11 is transmitted to the reducer 12 through the coupling. The reducer 12 reduces the speed and outputs the torque to the sprocket 13 mounted at its end. The sprocket 13 rotates and drives the transmission chain 2 meshing with it. The other end of the transmission chain 2 is connected to the drive sprocket 35 on the fixed sprocket set 3, thereby driving the drive sprocket 35 fixed on the drive shaft 36 to rotate. The end of the drive shaft 36 is connected to the driven shaft 37 through the coupling 34, synchronously transmitting the rotational power to the driven shaft 37. Both the drive shaft 36 and the driven shaft 37 are mounted in the fixed bearing support 31 and connected through the bushing 33 and... The shoulder structure restricts axial displacement. A sprocket 32 ​​is installed on the driven shaft 37. The sprocket 32 ​​rotates synchronously with the driven shaft 37 and drives the transmission chain 7 connected to it. The other end of the transmission chain 7 is connected to the sprocket 82 of the driven sprocket group 9 at the end of the waste discharge support 8, thus forming a horizontal circular motion trajectory between the fixed sprocket group 3 and the driven sprocket group 9. Multiple wear-resistant plates 5 are continuously fixed on the outer surface of the transmission chain 7 by bolts. The multiple wear-resistant plates 5 are spliced ​​to form a closed circular receiving plane. The metal scrap and dust with residual heat generated by the cutting operation slide from the waste outlet of the cutting machine to the receiving plane formed by the wear-resistant plates 5 under the action of gravity.

[0053] During operation, the second transmission chain 7, the second sprocket 32 ​​on the fixed sprocket group 3, and the third sprocket 82 on the driven sprocket group 9 are all located in the internal space below the receiving plane formed by the wear-resistant plate 5. The wear-resistant plate 5 blocks the path of waste and dust into the transmission components. The wear-resistant plate 5 carrying waste moves linearly towards the tail of the automatic waste discharge device along the second transmission chain 7. When the wear-resistant plate 5 moves to the driven sprocket group 9 and turns downward around the shaft 83 of the driven sprocket group 9, the waste it carries detaches from the surface of the wear-resistant plate 5 under the action of gravity and falls into the waste bin 10 placed separately below. The end of the scraper mechanism located at the waste discharge position at the tail of the line abuts against the surface of the turned wear-resistant plate 5, scraping the waste residue adhering to the surface into the waste bin 10.

[0054] When transmission chain 2 7 becomes loose, the adjusting bolt 85 on the tension support 2 81 of the driven sprocket group 9 is rotated, causing the end of the adjusting bolt 85 to push the milled flat positions at both ends of the shaft 83, which in turn causes the sprocket 3 82 on the shaft 83 and the bushing 2 84 to produce linear displacement, thereby achieving mechanical tension adjustment of transmission chain 2 7. At the same time, by loosening the fixing bolt on the tension support 14 of the drive mechanism 1, the motor 11 and the reducer 12 are translated using the position margin of the elongated hole mounting hole, thereby achieving tension adjustment of transmission chain 1 2. For cutting equipment with multiple waste outlets, multiple driven shafts 37 are coaxially connected in series at the end of the drive shaft 36 using multiple sets of couplings 34, and the power of a single drive mechanism 1 is synchronously transmitted to multiple sets of parallel transmission chains 2 7 and wear plates 5, driving multiple sets of waste collection worktables to operate synchronously and discharge waste.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
