Description

Technical Field

[0001] This utility model relates to the field of CNC punching machine technology, specifically a waste removal device for CNC punching machines. Background Technology

[0002] CNC punching machines generate a large amount of metal scrap during processing. These metal scraps are unavoidable byproducts of the process, so a waste removal device is needed.

[0003] A search revealed that Chinese Patent Publication (Announcement) No. CN221388617U discloses a waste removal device for a CNC punch press. This utility model uses a threaded sleeve and an extension tube to rise or fall, allowing the extension tube to get closer to the waste removal port of the CNC punch press, preventing debris and dust from scattering out during the waste removal process. Smaller debris and dust are absorbed by a vacuum cleaner, dust inlet pipe, and suction head. Simultaneously, by pulling the receiving box upwards, the fixing plate on the receiving box is disengaged from the insert rod on the support frame, allowing the receiving box to be removed from the support frame. Then, the waste inside can be taken out and processed uniformly.

[0004] However, the device still has the following defects: The applicant believes that the above device requires manual removal of the receiving box and dumping of waste materials. Each time the receiving box is full, it needs to be manually removed and dumped, which increases the labor intensity of workers. Moreover, each time waste materials are dumped, production needs to be suspended, which affects production efficiency. At the same time, the vacuum cleaner cannot absorb the waste materials when they are removed, and the flying dust and debris will increase the difficulty of cleaning.

[0005] Therefore, those skilled in the art have provided a waste removal device for a CNC punch press to solve the problems mentioned in the prior art. Utility Model Content

[0006] To solve the above problems, this utility model provides a waste discharge device for CNC punching machines.

A feed pipe is connected to the top of the fixed box, and an extension pipe is movably connected to the inner cavity of the feed pipe. A discharge port is provided on one side of the fixed box. An automatic waste removal mechanism is provided within the inner cavity of the fixed box. The automatic waste removal mechanism includes an inclined slide rail on the lower wall of the inner cavity of the fixed box. A conveyor belt is embedded within the inner cavity of the inclined slide rail. Flexible strips are fixedly connected at equal intervals to the outer surface of the conveyor belt. A through groove is provided at the top of the inclined slide rail, and the upper flexible strips all pass through the through groove and extend upwards. A dust collection box is fixedly connected to the other side of the fixed box. A first dust suction port is fixedly connected to the top of the extension pipe.

[0022] 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.

[0023] Please see Figures 1-4 The embodiments provided by this utility model are as follows:

[0024] This application discloses a waste removal device for a CNC punch press, including a fixed box 1. The top of the fixed box 1 is connected to a feed pipe 2, and the inner cavity of the feed pipe 2 is movably connected to an extension pipe 3. A discharge port 4 is opened on one side of the fixed box 1. An automatic waste removal mechanism is provided in the inner cavity of the fixed box 1. The automatic waste removal mechanism includes an inclined slide 5 provided on the lower wall of the inner cavity of the fixed box 1. A conveyor belt 6 is embedded in the inner cavity of the inclined slide 5. Flexible strips 7 are fixedly connected at equal intervals on the outer surface of the conveyor belt 6. A through groove is opened at the top of the inclined slide 5. The upper flexible strips 7 all pass through the through groove and extend upward. A dust collection box 8 is fixedly connected to the other side of the fixed box 1. A first dust suction port 9 is fixedly connected to the top of the extension pipe 3. A second dust suction port 10 is fixedly connected to both the front and back of the fixed box 1.

[0025] As a technical optimization of this utility model, the design of the inclined slide 5 allows the waste to slide down to the discharge port 4 under the action of gravity. During this process, the cooperation of the conveyor belt 6 and the flexible strip 7 can ensure that the waste is discharged continuously and evenly, thereby improving the waste discharge efficiency. It should be noted that the flexible strip 7 is made of soft material, such as rubber, silicone or polyurethane, but is not limited to these.

[0026] The first suction port 9 and the second suction port 10 can effectively remove dust and small debris generated during the waste collection and discharge process, keeping the working environment clean.

[0027] A connecting pipe 11 is fixedly connected to one side of both the first dust suction port 9 and the second dust suction port 10, and the end of the connecting pipe 11 is connected to the dust collection box 8.

[0028] As a technical optimization of this utility model, the positions of the first suction port 9 and the second suction port 10 can be adjusted according to the requirements. It should be noted that the connecting pipe 11 is a corrugated pipe, which can be lengthened or shortened according to the position adjustment of the first suction port 9 and the second suction port 10.

[0029] A fan 12 is fixedly installed at the bottom of the dust collection box 8. The air inlet pipe of the fan 12 is connected to the inner cavity of the dust collection box 8, and a purifier is fixedly installed at the end of the air inlet pipe.

[0030] As a technical optimization of this utility model, the fan 12 generates suction. When it is necessary to collect dust and debris, the fan 12 can create a negative pressure in the inner cavity of the dust collection box 8, thereby generating suction in the first suction port 9 and the second suction port 10. The collected dust and debris are then collected into the inner cavity of the dust collection box 8 through the connecting pipe 11. The purifier can filter the dust and debris, preventing them from entering the inner cavity of the fan 12 through the air inlet pipe, which can effectively extend the service life of the fan 12. At the same time, the dust and debris can be collected in the dust collection box 8.

[0031] The front and back sides of the inner cavity of the fixed box 1 are symmetrically provided with side slides 13, and the ends of the side slides 13 are flush with the discharge port 4.

[0032] As a technical optimization of this utility model, the side slide 13 can reduce the dead corners inside the fixed box 1, reduce the cleaning blind area, and prevent waste from accumulating inside the fixed box 1.

[0033] Electric slide rails 14 are embedded on both the front and back sides of one side of the inner cavity of the feed pipe 2. The inner cavity of the electric slide rail 14 is connected to a slide block 15 by a screw thread, and the slide block 15 is fixedly connected to one side of the extension pipe 3.

[0034] As a technical optimization of this utility model, the slide block 15 slides on the electric slide rail 14, which can drive the extension tube 3 to rise and fall, thereby enabling it to be used with CNC punching machines of different heights.

[0035] The conveyor belt 6 is driven by a motor, and a PLC controller 16 is fixedly mounted on the front of the fixed box 1.

[0036] As a technical optimization of this utility model, the motor used to drive the conveyor belt 6 is a servo motor. The servo motor can be controlled by the PLC controller 16, so that the speed of the conveyor belt 6 can be adjusted according to the amount of waste generated, ensuring that the waste can be discharged in time.

[0037] Working principle: The extension tube 3 can be raised and lowered by the cooperation of the electric slide rail 14 and the slide base 15, so that the extension tube 3 can be close to the waste discharge end of the CNC punch. Then, the conveyor belt 6 can be driven by the PLC controller 16. When the waste enters the inner cavity of the fixed box 1 through the extension tube 3, the waste will move towards the discharge port 4 under the action of the inclined slide rail 5 and the side slide rail 13. At the same time, the conveyor belt 6 and the flexible strip 7 will transport the waste to ensure that the waste is discharged continuously and evenly, improving the waste discharge efficiency. In addition, during the waste collection and discharge process, the fan 12 can generate suction, so that the first dust suction port 9 and the second dust suction port 10 can collect dust and debris at the same time, which can effectively reduce the difficulty of subsequent cleaning and ensure the air quality of the workshop.

Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0039] In summary, the above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model.
