Description

Technical Field

[0001] This utility model belongs to the field of chip handling technology, and specifically relates to a self-cleaning drum-type chip conveyor for machine tools. Background Technology

[0002] During machining, machine tools generate a large amount of chips. If these chips are not cleaned in time, they will not only affect the machining accuracy but may also damage the machine tool parts. Traditional machine tool chip conveyors, such as flat chain chip conveyors, have problems such as low chip removal efficiency and easy chip jamming. Spiral chip conveyors are prone to entanglement when handling long chips, resulting in poor chip removal. Scraper chip conveyors are not very effective at collecting fine chips. In addition, most chip conveyors tend to accumulate dirt after long-term use and lack an effective cleaning mechanism, requiring frequent manual disassembly and cleaning, which consumes a lot of manpower and time.

[0003] A drum-type chip conveyor is a type of filter based on a drum covered with screens. The drum rotates with the movement of the chain plate, increasing the specific surface area of ​​the filter surface, which is beneficial for continuous filtration. However, over time, fine particles will clog the filter pores, resulting in a decrease in the specific surface area of ​​the filter surface and poor filtration effect. Utility Model Content

[0004] This utility model addresses the problems of existing technologies by providing a self-cleaning roller-type chip conveyor for machine tools. The specific technical solution is as follows:

[0005] A self-cleaning drum-type chip conveyor for machine tools includes a drum assembly and a cleaning component disposed adjacent to the drum assembly. The cleaning component comprises components arranged sequentially along the rotation path of the drum assembly.

[0006] The rinsing section includes a rinsing pipe and a nozzle medium channel. The rinsing pipe is laid along the axial direction of the drum. Several sets of nozzles are arranged at equal intervals along the laying path of the rinsing pipe. The output direction of the nozzles is towards the drum.

[0007] The roller brush section includes a brush cylinder laid along the axial direction of the roller, with brush bristles adhered to the outside of the brush cylinder, and the roller brush section rotating in the opposite direction to the rotation direction of the roller.

[0008] And scraper.

[0009] As a further technical solution of this utility model, the rinsing part also includes a media channel, one end of which is connected to the rinsing pipe, and the other end of which extends through the housing and is connected to an external media source.

[0010] As a further technical solution of this utility model, the roller assembly includes a roller, a main shaft and a drive gear. The main shaft is coaxially connected to one end of the roller, and the main shaft is rotatably mounted on the housing through a bearing. The drive gear is coaxially connected to the outside of the main shaft.

[0011] One end of the brush cylinder is connected to a secondary shaft, and a driven gear that meshes with the driving gear is coaxially connected to the external secondary shaft.

[0012] As a further technical solution of this utility model, the scraper is arranged along the axial direction of the roller, and there is a gap between the scraper and the roller.

[0013] As a further technical solution of this utility model, the scraper includes a hard plate and a soft plate, and the soft plate is disposed on the end face of the hard plate facing the roller.

[0014] As a further technical solution of this utility model, the rinsing part, the roller brush part and the scraper are all arranged in the lifting section of the roller.

[0015] The beneficial effects of this utility model are as follows:

[0016] In this application, a flushing section, a roller brush section, and a scraper are sequentially arranged on the rotation path of the roller assembly. The flushing section uses high-pressure medium to initially flush away most of the loose debris particles. The roller brush section penetrates deep into the mesh through the rotation of the bristles to remove the more tightly adhered debris particles. The scraper further removes the remaining stubborn debris particles. The combination of the three achieves multi-dimensional and deep cleaning of the filter screen, which is more thorough than cleaning with a single device. As the roller rotates, each device works in turn to continuously clean the filter screen, ensuring that the filter screen maintains good filtration performance throughout the entire working process, greatly reducing filter screen clogging and increasing the continuous working time of the chip conveyor.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0025] Figure 1 A schematic diagram of the overall structure of a self-cleaning roller-type chip conveyor for machine tools is shown. Figure 1 The self-cleaning roller-type chip conveyor includes a housing 100, a chain plate assembly 200, a roller assembly 300, and a cleaning assembly 400. The chain plate assembly 200, roller assembly 300, and cleaning assembly 400 are all installed in the housing 100. The chain plate assembly 200 is typically composed of a sprocket and chain plates. The sprocket is driven to drive the chain plates to run stably. The chain plate assembly 200 and the roller assembly 300 are connected by a transmission. That is to say, the pitch and width of the chain plates in the chain plate assembly 200 are specially designed to ensure that they can drive the roller assembly 300 to rotate. The above is the basic operating principle of the chip conveyor. The housing 100, chain plate assembly 200, and roller assembly 300 are all prior art, and this application does not involve further improvements.

[0026] Figure 2 A schematic diagram of the cleaning component 400 is shown; Figure 2In this assembly, a cleaning component 400 is disposed adjacent to the roller assembly 300 and is used to clean the chips clogging the filter holes of the roller assembly 300. The cleaning component 400 includes a flushing section 410, a roller brush section 420, and a scraper 430 arranged sequentially along the rotation path of the roller assembly 300. The flushing section 410 is used to spray high-pressure water onto the filter screen surface to wash away the fine chips adsorbed on the filter screen; the roller brush section 420 is used to brush out the chips loosened by the high-pressure water in the filter holes; and the scraper 430 is used to scrape off stubborn large chips. The roller assembly 300 includes a roller 310, a main shaft 320, and a drive gear 330. The main shaft 320 is coaxially connected to one end of the roller 310, and the main shaft 320 is connected to a shaft. The bearing is rotatably mounted on the housing 100. The main shaft 320 is coaxially connected to the drive gear 330. The drum 310, the main shaft 320, and the drive gear 330 form a rotating whole. The rinsing part 410, the roller brush part 420, and the scraper 430 are all arranged around the drum 310, and the rinsing part 410, the roller brush part 420, and the scraper 430 are all arranged in the lifting section of the drum 310. The lifting section of the drum 310 refers to the section that rotates from the lowest point to the highest point of the drum 310 in the circumferential direction. Through this design, it can be ensured that the output direction of the rinsing part 410, the roller brush part 420, and the scraper 430 are all set in the opposite direction to the rotation direction of the drum 310, and the chips will not be blocked from falling vertically downward.

[0027] Figure 3 A schematic diagram of the mating structure of the rinsing section 410 and the drum 310 is shown; Figure 3 In the middle, the rinsing section 410 includes a rinsing pipe 411, a nozzle 412, and a media channel 413. The rinsing pipe 411 is laid along the axial direction of the drum 310. Several sets of nozzles 412 are arranged equidistantly along the laying path of the rinsing pipe 411. The output direction of the nozzles 412 is towards the drum 310. One end of the media channel 413 is connected to the rinsing pipe 411, and the other end of the media channel 413 extends through the housing 100 and is connected to an external media source. The media channel 413 is used to continuously supply high-pressure media to the rinsing pipe 411. The high-pressure media in the rinsing pipe 411 is sprayed onto the surface of the drum 310 through several sets of nozzles 412 to achieve a comprehensive rinsing of the drum 310. The media here can be any fluid without specific restrictions.

[0028] Figure 4 A schematic diagram of the mating structure of the roller brush 420 and the roller 310 is shown; Figure 4In the roller brush section 420, a brush cylinder 421 is laid along the axial direction of the roller 310. Brush bristles 422 are adhered to the outside of the brush cylinder 421, and the rotation direction of the brush bristles 422 is opposite to the rotation direction of the roller 310. The rotation of the brush cylinder 421 drives the brush bristles 422 to continuously roll and brush the surface of the roller 310 to brush off the loosened media, thus cooperating with the rinsing section 410. One end of the brush cylinder 421 is connected to a secondary shaft 423, and a driven gear 424 meshing with the driving gear 330 is coaxially connected to the external side of the secondary shaft 423. The brush cylinder 421, brush bristles 422, secondary shaft 423 and driven gear 424 form a rotating whole. Since the driven gear 424 meshes with the driving gear 330, the roller brush section 420 can rotate with the rotation of the roller 310, and the rotation direction of the roller brush section 420 and the roller 310 is opposite, which increases the rolling and brushing effect on the surface of the roller 310.

[0029] Figure 5 A schematic diagram of the mating structure of scraper 430 and roller 310 is shown; Figure 5 In the filter, the scraper 430 is arranged along the axial direction of the roller 310, and there is a gap between the scraper 430 and the roller 310. This can prevent the scraper 430 from scratching the filter screen and scrape off large-volume chips. The scraper 430 includes a hard plate 431 and a soft plate 432. The soft plate 432 is disposed on the end face of the hard plate 431 facing the roller 310. The soft plate 432 can be made of rubber so that the chips can penetrate the soft plate 432 and be intercepted.

[0030] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
