Description

Technical Field

[0001] This invention relates to a waste collection device, specifically a waste collection device for CNC machining equipment used in wood processing. Background Technology

[0002] CNC machining equipment is a mechanical automation device that uses digital information to control the displacement of machining tools and the displacement of parts to be machined. The ability to handle waste is one of the key factors affecting the efficiency of CNC machining.

[0003] CNC machining equipment used for board processing produces both wood chips and small pieces of waste from drilling and milling processes, as well as large pieces of waste from board cutting. For example Figure 1 The prior art CNC machining equipment for wood panel processing is shown. A CNC machine tool 200 is mounted on a frame 1. The CNC machine tool 200's cutting tools, such as drills and milling cutters, are located above a processing area 101. A first worktable 102 and a second worktable 103 are provided in the processing area 101. During wood panel processing, the first worktable 102 and the second worktable 103 are used to fix and support the panel being processed from below. Wood chips generated by this CNC machining equipment can be sucked away by a suction device, but small and large pieces of waste can only be manually cleaned up after the panel processing is completed.

[0004] In the existing technology, some traditional CNC machining equipment used for wood processing is equipped with waste collection boxes. These boxes are usually placed below the CNC machining area to collect small pieces of waste. However, collecting large pieces of waste is still inconvenient and requires manual cleaning.

[0005] When processing wood using CNC machining equipment, large boards are often involved. For example, one CNC machining machine can process boards up to 4000mm × 1250mm in size. The resulting waste material can also be quite large, typically ranging from 100mm × 100mm to 3000mm × 500mm, or even larger. Traditional waste collection bins can only collect small pieces, and large pieces close to the bin's cross-sectional size often fail to fall into the bin smoothly. Therefore, CNC machining equipment capable of processing large boards generally does not have waste collection bins; instead, waste is collected manually. The drawback of this method is...

[0006] ① Increase the actual usable area of ​​the processing equipment: It is necessary to add a work area near the equipment processing area for people to move around and for stacking waste materials. If there are large pieces of waste materials that are heavy or long, it is difficult for one person to move the waste materials smoothly. Two or more people are needed to operate together. Therefore, it is necessary to provide two or more work areas for people to move around.

[0007] ② The operation time for manually collecting waste materials is highly uncertain: skilled technicians can collect waste materials quickly, while ordinary technicians can collect them slowly; the time required for the same worker to remove waste materials each time also varies, ranging from ten to twenty seconds for some, to half a minute or even longer when fatigued or subject to other interference. There is no fixed waste material handling time, so CNC machining equipment needs to be paused frequently. Otherwise, the untimely collection of waste materials can easily affect the normal operation of subsequent processing, or cause defective products, or even equipment failure. Therefore, it is impossible to achieve continuous processing without stopping the machine.

[0008] ③ Increased likelihood of equipment failure or safety accidents: Large pieces of waste are generally heavy, and manual collection is labor-intensive, which can easily lead to worker fatigue. Workers who are fatigued are more likely to make operational errors, which increases the likelihood of equipment failure or safety accidents.

[0009] ④ It requires a lot of manpower, otherwise it will easily affect the working environment: manual collection of waste materials usually involves piling up the waste materials nearby, so at least 2 workers or more are required. 1 to 2 workers are responsible for collecting the processed waste materials in a timely manner and removing them from the processing area. In addition, workers are also required to clean up the waste materials piled up outside the processing area in a timely manner. Otherwise, it will easily cause the environment around the equipment to become messy and disorderly, which will worsen the working environment. Summary of the Invention

[0010] This invention provides a waste collection device for CNC machining equipment used in wood processing. It can automatically clean up the waste produced by the CNC machining equipment without the need for manual collection of waste in the processing area. This ensures that the CNC machining equipment will not stop due to waste disposal, which not only improves processing efficiency but also saves manpower and reduces the labor intensity of workers.

[0011] This invention discloses a waste collection device for CNC machining equipment used in wood processing, comprising two collection boxes: a first collection box and a second collection box. The first collection box is a movable, multi-functional collection box mechanism integrated with the machining table of the CNC machining equipment, serving as both a machining table and a collection box. This multi-functional collection box mechanism includes a first collection box body, a box base, a frame, a drive mechanism and a guide mechanism mounted on the frame, a unloading mechanism, and control components. The first collection box body is an elongated box with an open top surface serving as the machining table. The unloading mechanism is connected to both the first collection box body and the box base, controlling the first collection box to unload waste. The drive mechanism controls the first collection box body to move back and forth via the guide mechanism, allowing it to move between the machining area and a waste unloading end away from the machining area. The second collection box is located at the waste unloading end, collecting the waste transported and unloaded by the first collection box.

[0012] The frame described in this invention can be an independent frame or it can be integrated with the frame that houses the CNC machine tool and the sheet metal conveying mechanism. The sheet metal conveying mechanism is laid in a straight line along the frame from the sheet metal loading area to the finished sheet metal unloading area. The processing area of ​​the CNC machining equipment is located in the middle area between the loading area and the unloading area of ​​the sheet metal conveying mechanism.

[0013] As one feasible implementation, the sheet material conveying mechanism includes a feeding roller assembly in the feeding area, a guide rail and a clamp arranged parallel to the sheet material conveying direction, wherein the clamp is installed on the guide rail so that the clamp can move along the guide rail, and the sheet material is clamped and moved by the clamp during the processing of the sheet material.

[0014] When using the waste collection device of this invention to collect processing waste, after the processed board is finished, it is sent to the unloading area by the board conveying mechanism. During the feeding and clamping of the next processed board, the drive mechanism moves the first collection box to the waste unloading end by the guide mechanism. Under the action of the unloading mechanism, the waste is unloaded, for example, the collected waste is poured into the second collection box. Then the first collection box returns to the processing area to continue collecting waste, and so on. During the waste collection in the first collection box, the worker can handle the waste in the second collection box, which is far away from the processing area, empty the second collection box or replace it with an empty second collection box. The first collection box does not require machine downtime, thus not affecting the continuity of CNC machining. It not only improves processing efficiency, but also, because the unloading frequency of the first collection box can be set according to the size and shape of the waste material processed in each batch of plates, the waste material in the first collection box can be transferred in time, thereby avoiding the waste splashing caused by the first collection box when collecting waste. The second collection box is located far away from the processing area, so even if there is waste splashing when the first collection box dumps waste into the second collection box, it will not have an adverse effect on the processing area. Therefore, it can greatly reduce equipment failures caused by waste splashing.

[0015] The first collection box of the present invention has an opening on the top surface, and the first collection box can also be used as a workbench in the processing area.

[0016] The control component described in this invention can be a control device composed of sensors, programmable controllers, etc., used to control the movement of the sheet metal conveying mechanism and the action of the clamps in the waste collection device, the processing and positioning of the processed material, and the movement and unloading of the first collection box.

[0017] The present invention may also have the following preferred designs:

[0018] The driving mechanism of the present invention consists of a power source, a belt / chain transmission mechanism, and a power shaft connecting the power source and the belt / chain transmission mechanism. The belt / chain transmission mechanism comprises a transmission belt, a driving wheel, and a driven wheel. The power source is connected to the driving wheel via the power shaft. The guiding mechanism employs a slide rail and slider mechanism, consisting of a slide rail and a slider that cooperates with the slide rail. The slide rail is mounted on the frame along the reciprocating stroke of the first collection box. The driving wheel and the driven wheel are respectively mounted on the frame at or outside the end of the reciprocating stroke of the first collection box. The slider is connected to the box base and the transmission belt, respectively, so that the driving mechanism drives the first collection box to reciprocate along the slide rail using the slide rail and slider mechanism.

[0019] This invention employs two parallel sets of belt / chain drive mechanisms and two sets of guide mechanisms, arranged in pairs at both ends of the long side wall of the first collection box. The long side wall serves as the distance between the two sets of belt / chain drive mechanisms and the two sets of guide mechanisms. The two sets of belt / chain drive mechanisms are driven synchronously by the same power source; that is, a single power source outputs two power shafts, each connected to a drive wheel in one of the two sets of belt / chain drive mechanisms, causing the two drive belts to move synchronously. The upper parts of the two short side walls of the first collection box are hinged to the upper parts of two boxes. The boxes are connected to sliders in a slide rail mechanism via sliding seats, allowing the two boxes to move synchronously with the drive belts. The power source drives the two drive wheels to rotate forward and backward, controlling the reciprocating motion of the first collection box through the two sets of belt / chain drive mechanisms.

[0020] As a feasible implementation, the sliding seat of the present invention includes a base plate, a transmission belt connecting plate, and a cylinder mounting plate. The base plate is mounted on the upper surface of the slider, and the transmission belt connecting plate and the cylinder mounting plate are both fixedly mounted on the base plate. The lower end of the housing is also mounted on the base plate. The transmission belt connecting plate is a two-layer plate, and the transmission belt passes between the two layers. The contact surfaces of the transmission belt and the two layers are machined with toothed grooves of matching shape. The two layers clamp and fix the transmission belt, so that the transmission belt connecting plate can move synchronously with the transmission belt.

[0021] The present invention includes a limiting module for limiting the travel of the sliding seat. The limiting module is located on the frame at the end of the travel of the sliding seat, and anti-collision blocks are installed on the limiting module.

[0022] As a preferred unloading method for the first collection box of the present invention, one long side wall of the first collection box is a flip-open unloading door. The upper ends of both sides of the unloading door are hinged to the upper ends of the two adjacent short side walls. The unloading mechanism unloads waste by controlling the flipping of the first collection box and the opening and closing of its unloading door. Similarly, unloading can also be achieved by opening the bottom of the first collection box or by dumping waste from the top surface of the first collection box.

[0023] The unloading mechanism of the present invention includes a tilting cylinder for tilting the first collection box and a door cylinder for opening and closing the unloading box door of the first collection box.

[0024] The bottom wall of the first collection box is connected to a flipping cylinder at each end. The cylinder body of the flipping cylinder is hinged to the cylinder mounting plate of the sliding seat, and the telescopic rod of the flipping cylinder is hinged to the bottom wall of the first collection box. The first collection box is flipped by the synchronous extension and retraction of the telescopic rods of the two flipping cylinders.

[0025] Each end of the long side of the unloading box door is connected to a box door cylinder. The cylinder body of the box door cylinder is hinged to the lower middle end of the side of the unloading box door through a connecting rod. The telescopic rod of the box door cylinder is hinged to the short side wall of the first collection box. The telescopic rods of the two box door cylinders extend and retract synchronously to control the opening and closing of the unloading box door.

[0026] The first collection box of the present invention is provided with a flip-limiting mechanism on both short side walls. The flip-limiting mechanism consists of a hinge shaft, a limiting pin, and a limiting groove located in the arc shape of the box base. The axis lines of the hinge shaft located on the outer surface of the two short side walls coincide, and the axis lines of the limiting pin located on the two short side walls also coincide. The limiting groove is centered on the hinge shaft, and the limiting pin extends into the limiting groove to limit the flip angle of the first collection box.

[0027] The housing of the present invention has a shaft hole, on which a bearing with an eccentric sleeve is installed. The hinge shaft passes through the shaft hole and is fixedly connected to the inner ring of the bearing.

[0028] The multifunctional collection box mechanism of the present invention further includes a telescopic material support rod disposed at the top opening of the first collection box body and parallel to the long side wall of the first collection box body. The telescopic material support rod is connected to a material support rod cylinder, so that the telescopic material support rod can move back and forth between the edge of the top opening and the middle of the top opening of the first collection box body. The top surface of the telescopic material support rod is covered with a phenolic board.

[0029] The multifunctional collection box mechanism of the present invention further includes a material dropping plate disposed at the short side of the opening on the top surface of the first collection box body. When the first collection box body is located in the processing area, the material dropping plate is located below the processing area. One end of the material dropping plate is hinged to a short side wall of the first collection box body, and the other end extends into the interior of the first collection box body. A material dropping plate cylinder is also connected below the material dropping plate, and the top surface of the material dropping plate is covered with a phenolic board.

[0030] The blanking plate should be positioned below the processing area. During sheet metal processing, the telescopic rod of the blanking plate cylinder extends to bring the blanking plate to a horizontal position, and the telescopic rod of the support rod cylinder extends to position the telescopic support rod in the middle of the opening on the top surface of the first collection box. The blanking plate and the telescopic support rod serve as a worktable supporting the sheet metal being processed. After the sheet metal processing is completed, the telescopic rod of the support rod cylinder retracts to bring the telescopic support rod back to the edge of the opening on the top surface of the first collection box. Then, the telescopic rod of the blanking plate cylinder gradually retracts, causing one end of the blanking plate to gradually tilt downwards, allowing large pieces of waste material to slowly fall into the first collection box. The phenolic resin board covering the top surface of the blanking plate and the telescopic support rod helps prevent damage to the CNC machine tool's cutting tools.

[0031] A fixed crossbar can also be installed on the frame of the present invention. This crossbar is located between the first collection box and the plate conveying mechanism. The crossbar is parallel to the long side wall of the first collection box, and its upper surface, after being covered with phenolic board, is flush with the upper surface of the telescopic material support rod. The crossbar, in conjunction with the first collection box as a processing table, can further ensure the stability of the processing.

[0032] The present invention has the following significant effects:

[0033] 1. To meet the needs of efficient and safe production of CNC machining equipment for large-scale sheet metal, this invention replaces the existing manual waste collection method with a mechanical automatic waste collection method that delivers waste out of the processing area. The waste collection device has two waste collection boxes, one moving and one stationary. The first collection box is a movable multi-functional collection box integrated with the CNC machining table, serving as both a processing table and a movable collection box. After collecting waste from the sheet metal being processed in the processing area, the first collection box moves to the waste unloading end away from the processing area, unloading the waste into the second collection box. It then returns to the processing area for the next round of sheet metal processing, continuing to collect waste. This cycle repeats continuously, eliminating the need for manual waste collection in the processing area. During sheet metal processing, workers can empty the second collection box or replace it with an empty one, ensuring that the CNC machining equipment does not stop due to waste disposal. This prevents waste disposal from affecting the continuity of CNC machining, improving the processing efficiency of the equipment, saving manpower, reducing the labor intensity of workers, and improving the working environment.

[0034] 2. This invention can set the unloading frequency according to the size and shape of the waste material from each batch of boards. For example, if the waste material is small, it can be transferred once after processing several boards. If the waste material is large, it can be transferred once after processing. This allows the waste material to be transferred out of the processing area in a timely manner. Therefore, it can avoid the situation where the waste material falls and causes wood chips to splatter or the processing table to become uneven when too much waste material accumulates in the first collection box. Furthermore, the second collection box is located far away from the processing area, so that even if there is waste material splashing when the first collection box pours waste material into the second collection box, it will not have an adverse effect on the processing area. Therefore, it can greatly reduce equipment failures caused by improper waste material handling.

[0035] 3. In this invention, the first collection box has the function of automatically collecting and transferring waste materials. The unloading mechanism is achieved by a tilting cylinder controlling the tilting of the first collection box and a door cylinder controlling the opening and closing of the unloading box door. Furthermore, a tilting limit mechanism restricts the tilting angle of the first collection box. This allows for precise control of the unloading process, ensuring smooth unloading and accurate control of the waste processing time for each operation. This ensures consistent waste processing time, thereby guaranteeing continuous processing of the CNC machining equipment without downtime.

[0036] 4. The present invention can be equipped with a telescopic material support rod on the first collection box, which is connected to a material support rod cylinder. The position of the telescopic material support rod can be adjusted according to the processing area, so that the first collection box can not only collect small waste materials and chips generated during drilling, milling, etc., but also conveniently collect large pieces of waste materials. During the processing, the telescopic material support rod on the first collection box supports the processed plate from below and is used as a processing table. When the material is dropped, the telescopic material support rod retracts to the edge of the opening on the top surface of the first collection body, and large pieces of waste materials can fall into the collection box.

[0037] 5. The present invention can be equipped with a material dropping plate on the first collection box, and the material dropping plate is controlled by a material dropping cylinder. When processing the sheet material, the material dropping plate can be in a horizontal state and support the material together with the telescopic material support rod. When the sheet material is processed and the material is dropped, the material dropping plate gradually tilts so that large pieces of waste can slowly fall into the first collection box, avoiding the risk of waste collision and splashing caused by large pieces of waste suddenly falling into the first collection box.

[0038] 6. The slide rail slider mechanism of the present invention can use HIWIN linear guide rails of model HGW25 or HGW20 series to ensure the positional stability of the slider and the slide rail, so that the first collection box remains stable when used as a processing table.

[0039] 7. Because this invention can reduce manpower and labor intensity, improve the working environment, and thus effectively reduce the failure rate of CNC equipment, it greatly improves the production efficiency of the equipment, reduces the maintenance cost of the equipment, and thus effectively saves production costs.

Detailed Implementation

[0063] like Figure 2 As shown, the CNC machining equipment of the present invention includes a frame 1, a sheet metal conveying mechanism, and a CNC machine tool 200. The sheet metal conveying mechanism is laid in a straight line along the frame 1 from the sheet metal loading area to the sheet metal unloading area after processing. The processing area of ​​the CNC machining equipment is located in the middle area between the loading area and the unloading area of ​​the sheet metal conveying mechanism, that is, below the CNC machine tool 200. The sheet metal conveying mechanism includes a feeding roller assembly 301 in the loading area, a guide rail 302 parallel to the sheet metal conveying direction, and a clamp 303. The clamp 303 is mounted on the guide rail 302, allowing the clamp 303 to move along the guide rail 302. During the processing of the sheet metal, the clamp 303 clamps and moves the sheet metal 12.

[0064] like Figures 3 to 16As shown, a waste collection device for CNC machining equipment in wood processing according to the present invention includes two collection boxes, namely a first collection box and a second collection box 11. The first collection box is a movable multi-functional collection box mechanism integrated with the machining table of the CNC machining equipment, serving as both a machining table and a collection box. This multi-functional collection box mechanism includes a first collection box body 10, a box base 9, a frame 1, a drive mechanism and a guide mechanism mounted on the frame 1, a unloading mechanism, and control components. The first collection box body 10 is an elongated box with an open top surface serving as the machining table. The unloading mechanism is connected to both the first collection box body 10 and the box base 9, controlling the first collection box body 10 to unload waste. The drive mechanism controls the first collection box body 10 to move back and forth using the guide mechanism, allowing it to move between the machining area and a waste unloading end away from the machining area. The second collection box 11 is located at the waste unloading end and collects the waste transported and unloaded by the first collection box body 10.

[0065] In this embodiment, the frame 1 of the multifunctional collection box mechanism is integrated with the frame on which the CNC machine tool 200 and the plate conveying mechanism are installed, such as... Figure 2 As shown, the frame 1 is located behind the original frame on which the CNC machine tool 200 is installed, and is fixedly connected to the frame of the plate conveying mechanism perpendicular to it to form an integral frame. In other embodiments, the frame 1 of the collection box mechanism can also be set as an independent frame.

[0066] When the waste collection device of the present invention is used to collect processing waste, after the processed board 12 is processed, it is sent to the unloading area by the board conveying mechanism. During the feeding and clamping of the next processed board, the first collection box 10 unloads the waste under the action of the unloading mechanism and pours the collected waste into the second collection box 11. Then the first collection box 10 returns to the processing area to continue collecting waste, and so on.

[0067] The control component can be a control device composed of sensors, programmable controllers, etc., used to control the movement and unloading of the first collection box 10 of the waste collection device.

[0068] As a preferred embodiment

[0069] The top opening of the first collection box 10 has a size of 3147mm×307mm, which can collect large pieces of waste smaller than this opening size. The overall size of the first collection box 10 and the size of the top opening can be designed according to the processed plate and the size of the groove to be processed.

[0070] like Figures 3 to 5As shown, in this embodiment, the driving mechanism consists of a power source 6, a belt / chain transmission mechanism, and a power shaft connecting the power source 6 to the belt / chain transmission mechanism. The belt / chain transmission mechanism consists of a transmission belt 4, a driving wheel 5a, and a driven wheel 5b. The power source 6 is connected to the driving wheel 5a via a power shaft 7. The guiding mechanism adopts a slide rail slider mechanism, consisting of a slide rail 2 and a slider 3 that cooperates with the slide rail 2. The slide rail 2 is set on the frame 1 along the stroke of the first collection box 10. Specifically, the slide rail 2 can be laid on the square steel pipe 1a of the frame 1. The driving wheel 5a and the driven wheel 5b are respectively set on the frame 1 at the end of the stroke of the first collection box 10 or outside the end. The slider 3 is connected to the box base 9 and the transmission belt 4 respectively, so that the driving mechanism drives the first collection box 10 to reciprocate along the slide rail 2 by relying on the slide rail slider mechanism.

[0071] This embodiment employs two parallel sets of belt / chain drive mechanisms and two sets of guide mechanisms, arranged in pairs at both ends of the long side wall of the first collection box 10. The long side wall serves as the distance between the two sets of belt / chain drive mechanisms and the two sets of guide mechanisms. The two sets of belt / chain drive mechanisms are driven synchronously by the same power source 6. That is, the power source 6 outputs two power shafts 7, namely power shaft 7a and power shaft 7b. The two power shafts are respectively connected to the drive wheel 5a in the two sets of belt / chain drive mechanisms, so that the two drive belts 4 move synchronously. The power source 6 is a reducer, which is a device that integrates the drive motor and the reducer. It can be replaced by other equivalent power sources. The drive motor adopts a servo motor that can record the distance the slider 3 moves on the slide rail 2 and can rotate in both directions to accurately position the slider 3. The slide rail and slider mechanism adopts the HIWIN linear guide rail of model HGW25 or HGW20 series, or a slide rail and slider mechanism with equal or higher transmission stability and transmission accuracy can also be used.

[0072] like Figure 6 and Figure 7 As shown, in this embodiment, the upper parts of the two short side walls of the first collection box 10 are respectively hinged to the upper parts of the two box seats 9. The box seats 9 are connected to the slider 3 in the slide rail slider mechanism through the sliding seat 22, so that the two box seats 9 can move synchronously with the transmission belt 4, thereby controlling the movement of the first collection box 10.

[0073] The sliding seat 22 includes a base plate 22a, a transmission belt connecting plate 22b, and a cylinder mounting plate 22c.

The upper ends of the two sides of the discharge box door 18 are hinged to the upper ends of the two adjacent short side walls through the box door pivot 18a. The discharge mechanism discharges waste by controlling the first collection box 10 to flip and the discharge box door 18 to open and close.

[0076] The unloading mechanism includes a tilting cylinder 21 for tilting the first collection box 10 and a door cylinder 19 for opening and closing the unloading box door 18 of the first collection box 10.

[0077] As a preferred embodiment, the first collection box 10 is controlled to flip as follows:

[0078] A flipping cylinder 21 is connected to each end of the bottom wall of the first collection box 10. The cylinder body of the flipping cylinder 21 is hinged to the cylinder mounting plate 22c of the sliding seat 22. The telescopic rod of the flipping cylinder 21 is hinged to the bottom wall of the first collection box 10. The first collection box 10 is flipped by the synchronous extension and retraction of the telescopic rods of the two flipping cylinders 21. The two short side walls of the first collection box 10 are provided with flipping limiting mechanisms 8. The flipping limiting mechanism 8 is composed of a hinge shaft 8a, a limiting pin 8b and a limiting groove 9a located in the arc shape of the box seat 9. The axis of the hinge shaft 8a located on the outer surface of the two short side walls coincides. Similarly, the axis of the limiting pin 8b located on the two short side walls also coincides. The limiting groove 9a is centered on the hinge shaft 8a. The limiting pin 8b extends into the limiting groove 9a to limit the flipping angle of the first collection box 10.

[0079] The housing 9 has a shaft hole on which a bearing with an eccentric sleeve is installed. The hinge shaft 8a passes through the shaft hole and is fixedly connected to the inner ring of the bearing.

[0080] The opening and closing of the unloading box door are controlled as follows:

[0081] A door cylinder 19 is connected to each end of the long side of the unloading box door 18. The cylinder body of the door cylinder 19 is hinged to the lower middle end of the side of the unloading box door 18 through a connecting rod. The telescopic rod of the door cylinder 19 is hinged to the short side wall of the first collection box 10. The telescopic rods of the two door cylinders 19 extend and retract synchronously to control the opening and closing of the unloading box door 18.

[0082] The first collection box of this invention is used as a processing table in the following manner:

[0083] The multi-functional collection box mechanism also includes a telescopic material support rod 16 located at the top opening of the first collection box 10 and parallel to the long side wall of the first collection box 10. The telescopic material support rod 16 is connected to a material support rod cylinder 17, which enables the telescopic material support rod 16 to move back and forth between the edge of the top opening of the first collection box 10 and the middle of the top opening. The telescopic material support rod 16 can also be connected to two guide rods 20 that serve as motion guides. The top surface of the telescopic material support rod 16 is covered with a phenolic board.

[0084] The multi-functional collection box mechanism also includes a material drop plate 14 located at the short side of the opening on the top surface of the first collection box 10. When the first collection box 10 is located in the processing area, the material drop plate 14 is located below the processing area. One end of the material drop plate 14 is hinged to a short side wall of the first collection box 10, and the other end extends into the interior of the first collection box 10. A material drop plate cylinder 15 is also connected below the material drop plate 14. The top surface of the material drop plate 14 is covered with a phenolic board.

[0085] like Figure 17 As shown, a fixed crossbar 23 can also be provided on the frame of the present invention. The crossbar 23 is located between the first collection box 10 and the plate conveying mechanism. The crossbar 23 is parallel to the long side wall of the first collection box 10, and the upper surface of the crossbar is covered with phenolic board and is flush with the upper surface of the telescopic material support rod 16. It can assist the first collection box 10 in being used as a processing table, further ensuring the stability during the processing.

[0086] In this embodiment, after the first collection box collects the waste material from the processing area, it moves to the waste unloading end and unloads the waste material into the second collection box via the unloading mechanism. The process of returning to the processing area can be controlled within 15 seconds, which is less than the loading and clamping time of the processing plate 12, thus enabling continuous processing of the CNC machining equipment without stopping the machine. The waste processing time is shorter than that of manual processing, ensuring processing continuity while further improving work efficiency.

[0087] The above embodiments of the present invention are not intended to limit the scope of protection of the present invention, and the implementation of the present invention is not limited thereto. All modifications, substitutions, or alterations made to the above structure of the present invention based on the above description of the present invention, according to ordinary technical knowledge and common practice in the art, without departing from the basic technical concept of the present invention, should fall within the scope of protection of the present invention.
