Through the structural mode that the chain wheel and the mounting seat are arranged on the first connecting part, the hidden danger that chips are wound when the long shaft is connected is solved, the chain wheel and the scraper conveying chain are in meshed transmission, and the running track of the scraper conveying chain can be corrected; the baffle plate is arranged on the second connecting part, so that the phenomenon that the service life of the roller is influenced and chips are smoothly discharged due to the fact that large lumps of chips are directly contacted with the roller can be avoided; the third connecting portion set up the backplate, can prevent long bits winding axle, avoid chip cleaner jamming, jam, casing warp and the motor scheduling problem burns out even.

The scraper cylinder chip ejector will be described in conjunction with the embodiments to further understand the concept of the scraper cylinder chip ejector, referring to fig. 1-3, and comprises a main body, a driving member and a scraper conveyor chain 10, wherein the main body comprises a tail portion 20, an intermediate portion 30 and a head portion 40 which are sequentially spliced. Specifically, the driving member is a speed reduction motor, which is fixedly mounted on the top or side wall of the head 40. The scraper conveying chain circularly rotates along the track formed by the head part, the middle part and the tail part inner guide rails, and a chip removal channel is formed by the scraper conveying chain and the bottom surfaces of the head part, the middle part and the tail part, so that chips are circularly discharged. The tail part 20 comprises a tail shell 201, two mounting seats 202 and two chain wheels 203, the two mounting seats are symmetrically mounted on two inner sides of the tail shell far away from the head part, a step shaft is arranged at one end, opposite to the mounting seats, of the mounting seats, a bearing is mounted on the step shaft, and the two chain wheels are respectively sleeved on the bearing. And a sealing plate is arranged on one surface of the bearing far away from the mounting seat and is fixedly provided with the end part of the step shaft. The outer dimension of the sealing plate is larger than the inner diameter of the chain wheel, so that cutting scraps in the shell can be blocked, and the bearing is prevented from entering the cutting scraps to influence the service life; and on the other hand, the axial limiting device can be used as the axial limiting of the chain wheel. The sprocket wheel is engaged with the scraper conveying chain, and when the scraper conveying chain runs, the sprocket wheel rotates around the step shaft. The chain wheel structures are arranged at the two ends of the tail part, so that the mode that a long shaft is arranged in a penetrating way is avoided, the tail part space is open, and the hidden danger of winding and accumulation of chips in maintenance is avoided; on the other hand, the tail chain wheel is meshed with the scraper conveying chain, so that the running track of the conveying chain can be corrected, and the problems of deviation, derailment, accessory abrasion and the like of the conveying chain are avoided.

Further, the intermediate portion 30 includes a filter drum 301 and a baffle 302, which is located on a side of the filter drum toward the chip traveling direction, that is, between the filter drum and the tail portion. The head 40 includes a drive shaft 401 and a shield 402 that surrounds the drive shaft. Specifically, the head further includes a head housing 403 and a transmission wheel 404. The both sides of backplate and two inside walls fixed connection (accessible bolt fixed connection) of head casing to the backplate is located scraper blade conveying chain. I.e. the apron is between the upper and lower conveyor chains. Furthermore, one end of the guard plate is provided with a protection cavity matched with the diameter of the transmission shaft, and one end of the transmission shaft penetrates through the head shell and the protection cavity and is in driving connection with the speed reduction motor; the other end of the transmission shaft is rotationally connected with the outer wall of the head shell; the driving wheel is sleeved on the transmission shaft and meshed with the scraper conveying chain to rotate. Therefore, the transmission shaft is wrapped by the protection cavity, so that the hidden danger that the transmission shaft is blocked and cannot rotate due to the fact that cutting scraps wind the transmission shaft can be avoided. It should be noted that the extending end of the protection cavity in the axial direction of the transmission shaft is close to the transmission wheels on two sides, so that the gap between the end part of the protection cavity and the transmission wheels is reduced, and chips can be prevented from entering.

In one embodiment, the protective cavity of the guard plate can be bent through a thin plate and then fixedly installed on the guard plate through bolts to form a detachable structure.

In one embodiment, the cross-sectional shape of the protection cavity may be any one of a square or circle or a triangle or polygon, as long as it can accommodate the drive shaft.

In one embodiment, the guard plate is provided with a bulge facing the debris discharge channel at one end far away from the protection cavity, and the bulge extends axially along the transmission shaft and can be arranged in a plurality at intervals. The cross-sectional shape of the protrusion may be an arc, a U-shape, a V-shape or a W-shape.

In one embodiment, the cross section of the bulge is V-shaped for simple manufacture and convenient installation. And bending the thin plate to form a V-shaped groove. That is, a detachable V-shaped guide groove is provided on the guard plate, and an opening of the V-shaped guide groove faces the guard plate and is attached to the guard plate. Thus, when the cuttings are conveyed to the position of the guard plate from the middle part through the scraper conveying chain, the V-shaped guide groove can compress and guide the cuttings; but also can be used as a reinforcing rib of the guard plate to increase the strength of the guard plate. Furthermore, the V-shaped guide groove arranged on the guard plate can wrap the reinforcing ribs at the head part. Specifically, when the head is long or wide, a reinforcing rib needs to be fixed between the two inner sides of the head shell to ensure the strength of the head. In order to avoid winding of the reinforcing ribs by cutting scraps, the reinforcing ribs are wrapped when the V-shaped grooves are fixedly installed on the protection plate, and the reinforcing ribs are positioned in a space formed between the V-shaped grooves and the protection plate. Thus, the V-shaped groove also plays a protection role.

It should be noted that the space formed by the guard plate and the bottom of the head housing becomes larger gradually along the chip conveying direction, that is, the distance from the end of the guard plate provided with the V-shaped groove to the head housing is smaller than the distance from the guard plate to the bottom of the head housing at the transmission shaft. Thus, the chips are compressed first, and then the chips are more smoothly conveyed in the gradually larger space, and the conveying load is smaller.

In one embodiment, the V-shaped guide groove is connected with the guard plate through a bolt, so that the size or the V-shaped angle of the guide groove can be designed and changed according to actual working conditions to adapt to actual requirements. In order to avoid the bolt head from winding or scraping chips, a circular seal head can be screwed on the tail end of the bolt head.

In one embodiment, the intermediate part further comprises an intermediate housing to which the filter drum is rotatably connected, and the baffle plates are fixedly mounted on both inner sides of the intermediate housing by means of bolts. Optimally, the baffle is close to the setting of filtering roller, like this when the smear metal is carried and is carried, earlier with the baffle contact, can block and compress the bulk or the long bits of carrying through the baffle, avoid a large amount of smear metals direct and the cylinder contact, lead to cylinder jamming or cylinder filter screen damage. Further, the circumferential length of the baffle is larger than the length of the chips, namely the circumference of the U-shaped section of the baffle is larger than the length of the chips, so that the chips are not easy to wind on the baffle.

It should be noted that the distance from the lowest point of the baffle to the bottom of the intermediate housing is matched to the distance from the lowest point of the filter drum to the bottom of the intermediate housing, and most preferably, the lowest point of the baffle is lower than or equal to the lowest point of the filter drum (the filter drum refers to a drum for filtering chips, i.e., a filter screen). The distance from the lowest point of the baffle to the bottom of the middle shell is matched with the distance from the lowest point of the guard plate to the bottom of the head shell, so that cuttings can be conveyed conveniently.

In one embodiment, the filtering roller can be provided with a rotating chain wheel which is meshed with the scraper conveying chain to rotate, so that the filtering roller rotates while filtering, and the filtering efficiency is improved; on the other hand, the filtering roller is meshed with the scraper conveying chain, so that the rotating driving parts of the roller are reduced, and the chain wheel on the roller can be used as a supporting and limiting device of the scraper conveying chain, so that the deviation of the scraper conveying chain in the operation process is avoided.

In an embodiment, in order to better exert the function of the baffle, the included angle between the baffle and the chip removal direction is smaller than 90, namely, the included angle between one surface facing the chip removal direction and the chip removal direction is an acute angle, so that when a large amount of chips are conveyed to the position, the chips can be guided and extruded in the process of entering the space of the baffle from large to small, and the size of the chips is reduced. Furthermore, in order to achieve a better chip extrusion effect of the baffle plate, the angle between the baffle plate and the chip removal direction is set to be 50-75 degrees, so that a larger angle is avoided, the guiding effect is poor, and the extrusion effect cannot be achieved; on the other hand, the angle is too small, the volume of the chips is large, the chips are not easy to enter the space formed by the baffle and the shell, the chip clusters are separated by the baffle, and the conveying load is increased.

In the application, when the scraper type roller chip cleaner works, a chip-liquid mixture falls into the main body, and cutting liquid is filtered by the filtering roller and then is supplied to a machine tool; the chips are discharged from the chip outlet of the head through a channel formed by the scraper conveying chain and the bottom of the shell. When the massive or long scraps pass through the tail part, the tail part is not provided with a shaft which is arranged in a penetrating way, and the accommodating space is large and smooth, so the scraps are not easy to accumulate, and no parts which can be wound are arranged; when the cutting chips are conveyed to the baffle, the baffle and the conveying direction form an acute angle, so that the conveying channel of the cutting chips is gradually reduced from large to small in the process of passing through the baffle, a compression process is realized, the bulk cutting chips are compacted, the volume is reduced, and the cutting chips are not easily extruded with the roller when passing through the roller; on the other hand, the circumference of the baffle is larger than the chip, so that the entanglement is not easily generated at the baffle. When the chips are conveyed to the guard plate, the chips firstly enter a space formed by the guard plate and the bottom of the shell, and the chips are further compressed until the chips are discharged. When the transmission shaft is conveyed to the transmission shaft, the transmission shaft is wrapped by the protection cavity and cannot be wound, so that the rotation of the transmission shaft is not influenced.

Still need explain, afterbody sprocket, mount pad and baffle, backplate detachable in this application are connected with the casing, so this structure not only can design according to operating condition when the design, and when the product preparation was accomplished back in-service use, can reform transform the product of having made through preparation baffle, backplate or afterbody structure for its smooth and easy work.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
