Description

Technical Field

[0001] This utility model relates to the field of waste collection technology, and more specifically, to a waste collection device for CNC milling machines. Background Technology

[0002] In the field of machining, CNC milling machines are widely used due to their advantages of high precision and high efficiency. However, their processing generates a large amount of metal scrap with significant differences in shape and size. Currently, most scrap collection devices only have a single collection function and lack targeted grading and processing for scrap of different specifications.

[0003] Large-volume metal scraps typically have low impurity content and regular physical morphology, requiring only simple pretreatment such as crushing and demagnetization before being directly incorporated into the smelting process to be remanufactured into metal products. Small-volume metal scraps, however, have a large surface area, making them prone to contamination with non-metallic particles and other impurities generated by equipment wear during processing. They require special purification processes such as screening and airflow separation to remove impurities and improve purity before meeting smelting requirements. Furthermore, during melting, small-volume scraps, due to their larger surface area to volume ratio, experience a much higher rate of heat loss than large-volume scraps. Mixing them with large-volume waste not only increases energy consumption to maintain the smelting temperature but also leads to uneven heating within the smelting equipment due to differences in physical morphology, exacerbating wear on the equipment lining and shortening its lifespan. Existing collection devices do not classify waste by particle size at the source, resulting in a mixture of different sizes of waste during subsequent processing. Mixed processing, with its inability to accommodate the characteristics of different wastes using uniform process parameters, leads to energy waste and equipment wear, significantly reducing the efficiency and quality of metal waste recycling. Therefore, there is an urgent need for a device that can classify waste materials according to their size during the collection process. This device can achieve preliminary screening and classified storage of large, medium and small volume waste materials through a multi-stage sieve plate structure. It can provide preconditions for simple pretreatment of large particle waste materials and special purification of small particle fragments, avoid problems such as poor process adaptability and high energy consumption caused by mixed treatment, and improve the targeting and economy of metal waste recycling and treatment from the source.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] 1. This CNC milling machine waste collection device, through the cooperation of a multi-stage screening structure with first and second screen plates and a vibration mechanism, achieves waste collection by particle size classification. Large-volume debris is intercepted by the first screen plate and slides down the inclined plate surface to the left discharge port, entering the left cavity of the collection box; medium-volume debris passes through the first screen plate and is intercepted by the second screen plate, sliding down to the right discharge port and entering the right cavity; small-volume debris passes through the two-stage screen plates and falls into the middle collection cavity.

[0023] 2. This CNC milling machine waste collection device significantly improves the convenience of waste transportation through the design of universal wheels and a retractable handle at the bottom of the collection box: When movement is required, the rotating block is moved to disengage from the stop block, releasing the lock on the collection box. Pulling the telescopic rod drives the rotating rod to rotate around the hinge block, extending the handle to a suitable pulling angle. The universal wheels can then be used to easily pull the collection box to the waste disposal point, eliminating the need for manual handling and greatly reducing the labor intensity of operators. This solves the problems of low efficiency and easy spillage caused by manual handling in traditional devices. At the same time, the permanent magnet's attraction to the rotating rod allows the telescopic rod to automatically fit against the surface of the collection box, achieving handle storage and position locking. This ensures that the collection box is securely fixed during operation and flexible and controllable during movement, significantly improving the practicality and operational safety of the device.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] like Figures 1 to 8 As shown, this utility model provides a CNC milling machine waste collection device, comprising:

[0035] Fixed box 1, screening box 5 is fixedly installed inside fixed box 1, discharge port 6 is opened on both the left and right sides of screening box 5, guide plate 17 is fixedly installed at the bottom of screening box 5, collection box 3 is slidably connected to the bottom inside fixed box 1, partition plate 4 is fixedly installed inside collection box 3, there are two partition plates 4, the two partition plates 4 divide the inside of collection box 3 into three collection chambers with the same volume.

[0036] Vibration mechanism, which is installed on the outer surface of fixed box 1;

[0037] The screening mechanism is located inside the screening box 5;

[0038] The screening mechanism includes a fixed block 7, which is fixedly connected to the inside of the screening box 5. A spring 8 is fixedly installed at the bottom of the fixed block 7, and a moving rod 9 is fixedly installed at the bottom of the spring 8. The outer surface of the moving rod 9 is movably sleeved with the inside of the fixed block 7. A round rod 10 is fixedly installed at the top of the moving rod 9, and the bottom of the round rod 10 abuts against the top of the fixed block 7. A first screen plate 11 and a second screen plate 12 are fixedly sleeved on the outer surface of the round rod 10, and a square block 13 is fixedly installed inside the second screen plate 12.

[0039] The screening box 5, which is fixedly installed inside the fixed box 1, is used to classify waste materials. The discharge ports 6 on its left and right sides correspond to the discharge paths of waste materials of different specifications. The bottom guide plate 17 is inclined to guide small particles of waste materials to fall into the middle of the collection box 3. The two partitions 4 inside the collection box 3 divide it into three equal-volume cavities, which correspond to the storage areas of large, medium and small particles of waste materials, respectively. In the screening mechanism, the fixed block 7 cooperates with the moving rod 9 through the spring 8 to provide elastic support for the first screen plate 11 and the second screen plate 12: the spring 8 buffers the impact force of the screen plate when vibrating, the moving rod 9 slides along the inside of the fixed block 7 to ensure the stability of the vibration direction of the screen plate, the round rod 10 connects the two screen plates to achieve synchronous vibration, and the square block 13 is fixed inside the second screen plate 12 to receive the thrust of the vibration mechanism, and finally form a stable up and down vibrating screening action.

[0040] The vibration mechanism includes:

[0041] Motor 14, the back of motor 14 is fixedly connected to the front of fixed box 1, and the output end of motor 14 is fixedly sleeved with rotating shaft 15;

[0042] Elliptical block 16, the interior of elliptical block 16 is fixedly sleeved with the outer surface of rotating shaft 15, and the top of elliptical block 16 abuts against the bottom of square block 13.

[0043] The vibration mechanism drives the elliptical block 16 on the rotating shaft 15 to rotate via the motor 14. Utilizing the eccentric contour characteristics of the elliptical block 16, its top end periodically presses against the square block 13 during rotation, forcing the second screen plate 12 to vibrate up and down. This vibration is transmitted to the first screen plate 11 via the round rod 10, causing the two screen plates to vibrate synchronously, thus achieving vibratory screening of waste materials. The motor 14 is fixed to the front of the fixed box 1 to ensure stable power output.

[0044] The top of the fixed box 1 is fixedly installed with a working platform 2, the bottom of the working platform 2 is fixedly connected to the top of the screening box 5, the top of the working platform 2 is fixedly installed with a baffle 20, the top of the working platform 2 is fixedly fitted with a mesh 18, and the inside of the working platform 2 is fixedly installed with a guide block 19.

[0045] The work platform 2 is fixed to the top of the fixed box 1 and serves as the operating plane for workpiece processing. The top baffle 20 is arranged around it to form a physical barrier to block the flying debris during processing. It works in conjunction with the central strainer 18 to allow the debris to fall through the strainer 18. The guide block 19 is installed at an angle inside the work platform 2 to receive the debris falling from the strainer 18 and guide it to slide to the left and right sides.

[0046] The work platform 2 is internally fixedly fitted with a feeding channel 21, and the outer surface of the feeding channel 21 is fixedly fitted with a feeding bin 22. The outer surface of the feeding bin 22 is fixedly connected to the interior of the bottom end of the work platform 2.

[0047] The feeding channel 21 is located inside the working platform 2, allowing the debris guided by the guide block 19 to enter the interior of the feeding channel 21. The feeding bin 22, which is fixedly sleeved on its outer surface, is connected to the top of the screening box 5, forming a material transmission path from top to bottom.

[0048] The top of the feed hopper 22 is equipped with a fan 23, and a filter screen 24 is installed at the air outlet of the fan 23.

[0049] The blower 23 is located at the top of the feed hopper 22. The filter 24 at its outlet can filter impurities in the intake airflow and protect the impeller of the blower 23 from damage by debris. When the blower 23 is working, the negative pressure generated will actively draw debris from the working platform 2 into the feed hopper 22 through the feed channel 21, while accelerating the conveying speed of debris to the screening box 5 and improving the overall collection efficiency.

[0050] The bottom of the work platform 2 is fixedly installed with a bracket 25, and the outer surface of the bracket 25 is fixedly connected to the outer surface of the fixed box 1.

[0051] Due to the design of the bracket 25, it can provide good support for the entire equipment, allowing the entire equipment to be placed stably on the ground.

[0052] Among them, a stop block 26 is fixedly installed on the front of the partition 4, a permanent magnet 27 is fixedly sleeved inside the front of the partition 4, and a caster wheel 28 is fixedly installed at the bottom of the partition 4.

[0053] The casters 28 are installed at the bottom of the collection box 3. They are made of quiet and wear-resistant material, making it easy for operators to push the collection box 3 to move after unlocking, thus reducing the labor intensity of handling.

[0054] Among them, a hinge block 29 is fixedly installed at the bottom of the front side of the partition 4, and a rotating rod 30 is hinged inside the hinge block 29. The back of the rotating rod 30 is in contact with the front side of the permanent magnet 27.

[0055] The hinge block 29 serves as the fulcrum for the rotation of the rotating rod 30. It is fixed to the bottom front of the collection box 3, allowing the rotating rod 30 to rotate around its axis. When the back of the rotating rod 30 is in contact with the permanent magnet 27, it remains stable under the action of magnetic force to achieve the storage effect.

[0056] The rotating rod 30 has a telescopic rod 31 that is movably connected inside it, and a handle 32 is fixedly installed at the top of the telescopic rod 31.

[0057] The telescopic rod 31 is sleeved inside the rotating rod 30 and can slide along its axial direction. The handle 32, fixed at the top, adjusts the operating height by extending and retracting the telescopic rod 31 to accommodate the needs of operators of different heights. When the handle 32 is pulled, the telescopic rod 31 drives the rotating rod 30 to rotate around the hinge block 29, rotating the handle 32 to a suitable pulling angle, thus improving operating comfort and flexibility.

[0058] Among them, an arc-shaped block 33 is fixedly installed on the outer surface of the fixed box 1, and a rotating block 34 is movably sleeved on the outer surface of the arc-shaped block 33. The outer surface of the rotating block 34 abuts against the outer surface of the stop block 26, and the back of the rotating block 34 is in contact with the front of the partition 4.

[0059] The arc-shaped block 33 is fixed to the outer surface of the fixed box 1, serving as a rotational support for the rotating block 34. Its arc-shaped profile allows the rotating block 34 to swing around the fitting point as the axis. When the outer surface of the rotating block 34 abuts against the stop block 26, it forms a mechanical limit on the collection box 3 to ensure its stability; when the rotating block 34 rotates away from the stop block 26, the limit is released, allowing the collection box 3 to be pulled out.

[0060] Working principle and usage process of this utility model:

[0061] When the operator processes the workpiece at the top of the work platform 2, the generated debris is first blocked by the surrounding baffles 20 to prevent it from splashing outside the device. Then the debris falls through the strainer 18 at the top of the work platform 2 onto the inclined guide block 19. Since the guide block 19 is tilted left and right, the debris will slide naturally along its sides to the feed channel 21. At this time, the operator starts the blower 23. The blower 23 generates suction through the feed channel 21 to suck the debris in the channel into the feed bin 22. Then, under the action of gravity, these debris fall from the feed bin 22 onto the first screen plate 11 inside the screening box 5.

[0062] Next, the operator starts the motor 14. The shaft 15 at the output end of the motor 14 drives the elliptical block 16 to rotate synchronously. As the elliptical block 16 rotates, its outer surface will repeatedly press the square block 13, thereby pushing the square block 13 to drive the second screen plate 12 to move up and down reciprocally. Since the second screen plate 12 is rigidly connected to the first screen plate 11 through the round rod 10, it can drive the first screen plate 11 to vibrate synchronously. The fixed block 7, spring 8 and moving rod 9 below the screen plate constitute a stable structure: the moving rod 9 passes through the fixed block 7 and is connected to the screen plate. The spring 8 is sleeved on the moving rod 9. During the vibration, it provides buffer force through compression and reset to ensure that the two-stage screen plates vibrate smoothly without deviation.

[0063] During vibration, debris of different volumes is classified according to the size of the screen holes: larger debris that cannot pass through the mesh of the first screen plate 11 is intercepted on the surface of the screen plate. Since the first screen plate 11 is tilted to the left, the debris gradually moves to the left under the action of vibration inertia, and finally falls into the independent collection chamber on the left side of the collection box 3 through the discharge port 6 on the left side of the screening box 5, which is separated by the partition plate 4; medium-sized debris with a size between the mesh of the two screen plates will pass through the first screen plate 11 and be intercepted by the second screen plate 12 tilted to the right below. Similarly, it moves to the right during vibration and enters the right collection chamber of the collection box 3 through the discharge port 6 on the right side; the smallest debris will pass through the two screen plates and fall onto the guide plate 17, and slide down the guide plate 17 to the collection chamber in the middle of the collection box 3, completing the three-level classification and collection.

[0064] When it is necessary to transfer the collected debris, the operator first moves the rotating block 34 fitted on the arc-shaped block 33, causing it to rotate outward around the fitting point, disengaging from the contact state with the front stop block 26 of the collection box 3, thus releasing the locking limit on the collection box 3. Then, the operator pulls the handle 32 fixed to the top of the telescopic rod 31, causing the telescopic rod 31 to slide upward along the inside of the rotating rod 30. This then drives the rotating rod 30 to rotate around the bottom hinge block 29, unfolding the handle 32 to an angle that facilitates pushing and pulling. Since the bottom of the collection box 3 is equipped with casters 28, the operator can easily push it using the handle 32. The collection box 3 is moved to the waste disposal point. After the waste is disposed of, the operator needs to place the partition 4 back inside the fixed box 1. At this time, the operator first presses down the handle 32 to retract the telescopic rod 31, and then drives the rotating rod 30 to return to its original position around the hinge block 29. When the rotating rod 30 is in contact with the front of the collection box 3, the permanent magnet 27 installed inside the front of the collection box 3 attracts the rotating rod 30 with magnetic force, making it stably in contact, so as to achieve the storage effect. Then the operator reverses the rotation block 34 to make it abut against the stop block 26 again to lock the position of the collection box 3 and complete the entire transportation process.
