Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, specifically to a CNC machining scraper-type iron chip conveying device. Background Technology

[0002] The scraper-type chip conveyor is an automatic chip removal device specifically designed for CNC machine tools. Its core structure consists of a chain-driven scraper installed inside the trough. During operation, the scraper moves back and forth close to the bottom of the trough, continuously scraping metal chips such as cast iron and steel chips generated during CNC machine tool processing to the chip collection box or a designated location. This device features high conveying efficiency, large load capacity, and high reliability, while also reducing the burden of manual cleaning. It is an important auxiliary device for achieving efficient and automated operation in modern production lines.

[0003] During the design process of this utility model, the following problems were found in the existing technology: In the existing scraper-type conveying device, the scraper is mostly close to the bottom of the trough to scrape off the iron filings, which makes it convenient for the device to scrape off the iron filings thoroughly. However, when there are too many iron filings or large clumps of iron filings, the resistance increases sharply. If the scraper is forcibly scraped, it is easy to cause the chain to jam, overload, or even burn out the motor. Utility Model Content

[0004] The purpose of this invention is to provide a CNC machining scraper-type chip conveying device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a CNC machining scraper-type chip conveying device, comprising a device frame, a drive assembly inside the device frame, and a plurality of scraper assemblies inside the drive assembly; the device frame includes a conveyor frame, with grooves on both sides of the inner wall of the conveyor frame, a feed inlet fixedly installed at the upper end of one side of the conveyor frame, and a discharge outlet on the other side of the conveyor frame; the drive assembly includes two transmission rods, which are rotatably mounted on both sides of the inner wall of the conveyor frame, and are distributed in parallel, with two first gears fixedly mounted on the outer surface of each transmission rod, and a transmission chain meshing between the two first gears on the same side, and a drive motor installed on the side end of one of the transmission rods extending to the outside of the conveyor frame; the scraper assembly includes a main scraper, with a secondary scraper rotatably mounted at the lower end of the main scraper, a metal hinge installed between the main scraper and the secondary scraper, and brackets fixedly mounted at the rear ends of both the main scraper and the secondary scraper, with a telescopic rod fixedly mounted between the two brackets, and a return spring sleeved on the outside of the telescopic rod.

[0006] The beneficial effects of this utility model are as follows: by setting a secondary scraper, when there are a lot of iron filings inside the device, the secondary scraper at the bottom will be pushed backward by the iron filings. At this time, the telescopic rod retracts and the return spring is compressed, so that some iron filings pass through the bottom of the scraper assembly and wait for the next scraper assembly to scrape. This avoids forced scraping and achieves the effect of preventing chain jamming, overload, or even motor burnout during the use of the device, thereby improving the service life of the device.

[0007] To guide the iron filings: Further configuration: several bearings are rotatably installed inside the conveyor frame, and a guide plate is fixedly installed at the bottom of the feed inlet.

[0008] By adopting the above technical solution, when iron filings enter one end of the device from the feed inlet, they are guided by the guide plate and fall above the crushing scraper, which facilitates the subsequent dispersion of the iron filings by the crushing scraper.

[0009] To achieve synchronous rotation of the rotating rod: The configuration is further defined as follows: one side of one of the transmission rods is provided with a rotating rod, one side of the rotating rod is rotatably installed inside the conveyor frame, and the other side extends through to the outside of the conveyor frame; a second gear is fixedly installed on the outer surface of both the transmission rod and the rotating rod, and the two second gears are meshed with the same toothed transmission belt.

[0010] By adopting the above technical solution, the drive motor is started, which drives the transmission rod to rotate. The transmission rod is driven by a toothed belt, which ultimately drives the rotating rod to rotate.

[0011] To achieve the limiting of the toothed drive belt: The toothed transmission belt is further configured such that limiting discs are provided on both sides, and the limiting discs are fixedly installed on the outer surfaces of the transmission rod and the rotating rod.

[0012] By adopting the above technical solution, limiting discs are set on both sides of the toothed drive belt to prevent the toothed drive belt from shifting after rotating for too long, thus affecting the transmission effect.

[0013] To achieve preliminary treatment of iron filings: A further configuration is provided: several crushing scrapers are fixedly installed on the outer surface of the rotating rod.

[0014] By adopting the above technical solution, when iron filings enter the conveyor frame through the feed inlet, there may be large clumps of iron filings. These are broken up by the rotating crushing scraper, which facilitates the subsequent scraping and conveying of iron filings by the scraper assembly.

[0015] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

Two first gears 22 are fixedly installed, and a transmission chain 23 meshes between the two first gears 22 on the same side. One of the transmission rods 21 extends through the outside of the conveyor frame 11 and is equipped with a drive motor 24. The scraper assembly 3 includes a main scraper 31, and a secondary scraper 32 is rotatably installed at the lower end of the main scraper 31. A metal hinge 33 is installed between the main scraper 31 and the secondary scraper 32. A bracket 34 is fixedly installed at the rear end of both the main scraper 31 and the secondary scraper 32. A telescopic rod 35 is fixedly installed between the two brackets 34, and a return spring 36 is sleeved on the outside of the telescopic rod 35.

[0020] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, several bearings 13 are rotatably installed inside the conveyor frame 11, and a guide plate 15 is fixedly installed at the bottom of the feed inlet 14.

[0021] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, one side of one of the transmission rods 21 is provided with a rotating rod 25. One side of the rotating rod 25 is rotatably installed inside the conveyor frame 11, and the other side extends through to the outside of the conveyor frame 11. A second gear 26 is fixedly installed on the outer surface of both the transmission rod 21 and the rotating rod 25. The two second gears 26 are meshed with the same toothed transmission belt 27.

[0022] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, both sides of the toothed transmission belt 27 are provided with limiting discs 28, which are fixedly installed on the outer surfaces of the transmission rod 21 and the rotating rod 25.

[0023] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, several crushing scrapers 29 are fixedly installed on the outer surface of the rotating rod 25.

[0024] The computer software involved in the hardware carriers such as the drive motor in the technical solution is software technology known to those skilled in the art. It is merely applied to the aforementioned hardware carriers. In other words, the computer software portion of the technical solution is an essential technical feature for solving the aforementioned technical problem, constituting a necessary technical feature for the technical problem solved by this application, but it is not a differentiating technical feature or a point of technical improvement. The applicant has not made any technical improvements to the computer software portion involved in the aforementioned related hardware carriers, nor is it a key technical point of the invention.

[0025] Therefore, the "drive motor" and the like mentioned in this application are physical functional modules that combine computer software programs or protocols in the prior art with the hardware carrier of this application. The computer software programs involved in these physical functional modules are all technologies known to those skilled in the art and are not improvements of this application. The improvement of this application should be the interaction relationship between the various physical functional modules, that is, the improvement of the overall structure of the automatic dipping machine of this application, so as to solve the corresponding technical problems to be solved by this application.

[0026] The working process of this CNC machining scraper-type chip conveying device is as follows: First, the user places the device in the designated position, positioning the feed inlet 14 below the chip outlet of the CNC machining device. When the chips fall into the feed inlet 14, they are guided by the guide plate 15 and fall onto the upper part of the crushing scraper 29. Then, the drive motor 24 (model: HC-KFS73) is started, driving one of the transmission rods 21 to rotate. Through the toothed transmission belt 27, the drive rod 25 and the crushing scraper 29 rotate. The crushing scraper 29 scrapes the chips to the bottom of the conveyor frame 11 and to a position that the scraper assembly 3 can reach. At the same time, the rotation of the transmission rod 21 is transmitted through the transmission chains 23 on both sides, driving the transmission rod 21 on the other side to rotate. This causes the transmission chains 23 on both sides to drive several transmission chains 23 to rotate. During the movement of the scraper assembly 3, The bottom of the auxiliary scraper 32 is in contact with the inner bottom surface of the conveyor frame 11. The main scraper 31 and the auxiliary scraper 32 scrape the iron filings at the front of the main scraper 31 and drive it forward. When there are too many iron filings scraped by the front end of one or more main scrapers 31, the resistance is too great. At this time, the auxiliary scraper 32 will be pushed backward by the iron filings at the bottom. The auxiliary scraper 32 rotates backward, and the bracket 34 abuts against the telescopic rod 35 and retracts upward. The telescopic rod 35 is compressed, so that some iron filings are left in place through the gap at the bottom of the auxiliary scraper 32, waiting for the next scraper assembly 3 to scrape. This prevents the chain from jamming, overload, or even the motor from burning out. When there are fewer iron filings at the bottom or the resistance is not great, the return spring 36 rebounds, so that the auxiliary scraper 32 is vertical again at the bottom of the conveyor frame 11 and performs scraping work until the iron filings are scraped and sent to the discharge port 16 for discharge.
