[0002] A large amount of chips will be generated during the machining process of CNC machine tools. Different metal materials will produce chips of various shapes during the machining process. When the material of the processed material is various steel materials, the chips generated during the machining process are mainly in the form of clumps, rolls, and strips. The clumps, rolls, and strips of chips are very fluffy in their natural stacking state. Therefore, the chip accumulation volume is large, which brings great trouble to cleaning the chips, and often requires multiple dumping, affecting production efficiency. Summary of the invention

[0003] The technical problem to be solved by the present invention is: in order to overcome the problem in the prior art that strip chips are very fluffy in a natural stacking state, the chip stacking volume is large, which brings great trouble to cleaning the chips and often requires multiple outflows, affecting the production efficiency, a chip removal and extrusion integrated machine for machine tools is provided.

[0004] The technical solution adopted by the present invention to solve the technical problem is: a chip removal and extrusion integrated machine for machine tools, characterized in that it includes:

[0005] Chip removal mechanism: the chip removal mechanism comprises a shell, one end of the shell is provided with a chip inlet, the other end is provided with a chip outlet, a conveying assembly is provided in the shell, and the conveying assembly connects the chip inlet and the chip outlet;

[0006] Extrusion mechanism: The extrusion mechanism includes a casing, an extrusion inlet is provided at the upper end of the casing, an extrusion outlet is provided at the lower end, the extrusion inlet is located directly below the chip outlet, an upper extrusion assembly is rotatably mounted at the upper end of the casing, and a lower extrusion assembly is rotatably mounted at the lower end of the casing;

[0007] The upper extrusion assembly comprises an upper extrusion roller, on which a flip push rod protruding from the roller body is retractably provided, and the upper extrusion roller is provided with a flip push rod, the two upper extrusion rollers are located at the same height, the two upper extrusion rollers are parallel and spaced apart, and one side of the two upper extrusion rollers is in contact with the inner wall of the casing;

[0008] The lower extrusion assembly comprises a lower extrusion roller, two of the lower extrusion rollers are located at the same height, the two lower extrusion rollers are parallel and spaced apart, the gap between the two lower extrusion rollers is smaller than the gap between the two upper extrusion rollers, and one side of the two lower extrusion rollers is in contact with the inner wall of the casing;

[0009] Rotation mechanism: The rotation mechanism drives the two upper squeezing rollers to rotate relative to each other, and at the same time drives the two lower squeezing rollers to rotate relative to each other.

[0010] The chip removal and extrusion integrated machine for machine tools of the present invention, when in use, the chips cut off the machine tool enter the shell from the chip inlet, are transported to the chip outlet through the conveying assembly in the shell, and the chips fall into the extrusion inlet from the chip outlet. The upper end of the inner part of the shell is rotatably installed with an upper extrusion assembly, and the lower end of the inner part is rotatably installed with a lower extrusion assembly. The upper extrusion assembly includes an upper extrusion roller, and a flip push rod protruding from the roller body is retractably provided on the upper extrusion roller. The two upper extrusion rollers are located at the same height, and the two upper extrusion rollers are arranged in parallel and at intervals. The rotating mechanism drives the two upper extrusion rollers to rotate relative to each other, and drives the two The two lower squeezing rollers rotate relatively, and the chips move between the two upper squeezing rollers driven by the flip push rod. After the chips are squeezed by the two upper squeezing rollers, their volume is reduced. One side of the two upper squeezing rollers fits against the inner wall of the casing, and the chips cannot pass between the upper squeezing rollers and the casing, but can only pass between the two upper squeezing rollers, so that all the chips can be squeezed; the chips squeezed by the upper squeezing rollers move between the two lower squeezing rollers under the action of the lower squeezing roller. Since the gap between the two lower squeezing rollers is smaller than the gap between the two upper squeezing rollers, the two lower squeezing rollers can squeeze the chips The one-step extrusion further reduces the volume of the chips. At the same time, the chips are squeezed and compressed together, which makes it easier to clean them, thereby improving the chip cleaning efficiency. One side of the two lower extrusion rollers is in contact with the inner wall of the casing. The chips cannot pass between the lower extrusion rollers and the casing, but can only pass between the two lower extrusion rollers, so that all the chips can be squeezed. Since the chips are in strip shape, the strip chips are easy to be entangled on the flip push rod during the rotation of the upper extrusion roller. If the strip chips wrapped around the flip push rod are not cleaned in time, the strip chips on the upper extrusion roller will be entangled more and more. It affects not only the rotation of the upper extrusion roller, but also the extrusion efficiency of the cutting. If the rotation of the upper extrusion roller is stopped regularly to clean the upper extrusion roller, the efficiency of extruding the chips of the present invention is low. Therefore, it is necessary to clean the strip chips wrapped on the flip push rod in time when the upper extrusion roller does not stop rotating. Therefore, the upper extrusion roller is retractably provided with a flip push rod protruding from the roller body. The strip chips wrapped on the flip push rod can be scraped off during the process of the push rod being retracted into the upper extrusion roller, thereby realizing timely cleaning of the strip chips wrapped on the flip push rod when the upper extrusion roller does not stop rotating.

[0011] The cam body is provided with a plurality of intermediate rollers, the intermediate rollers being provided with a plurality of intermediate rollers and a plurality of intermediate rollers being provided with a plurality of intermediate rollers, and the intermediate rollers being provided with a plurality of intermediate rollers and a plurality of intermediate rollers being provided with a plurality of intermediate rollers. The cam is fixedly mounted on the inner shaft, and the plurality of cams are respectively located in the plurality of accommodating cavities, and the inner ends of the plurality of flip push rods in the plurality of limiting through holes connected with the same accommodating cavity are all in contact with the outer circumferential surface of the cam; when the flip push rods in the two upper extrusion rollers are arranged relatively to each other, the length of the flip push rod extending out of the limiting through hole is the longest, which is the longest flip push rod; on the same upper extrusion roller, the flip push rod directly opposite to the longest flip push rod is the shortest flip push rod, and the shortest flip push rod is completely accommodated in the limiting through hole. During the rotation of the upper extrusion roller, the plurality of flip push rods on the same circumference gradually change from the longest flip push rod to the shortest flip push rod, and then gradually change from the shortest flip push rod to the longest flip push rod. If there are strip chips wrapped around the flip push rod, during the rotation of the front roller body, the middle roller body and the rear roller body, the cam does not rotate, and the flip push rods on the front roller body, the middle roller body and the rear roller body rotate around the central axis of the front roller body. During the rotation, the flip push rod always fits the outer circumferential surface of the cam, and the flip push rod gradually changes from the longest flip push rod to the shortest flip push rod, and the flip push rod gradually retracts into the guide hole. Since the radius of the guide hole is equal to the radius of the flip push rod, when the flip push rod retracts into the guide hole, the outer circumferential surfaces of the front roller body, the middle roller body and the rear roller body scrape the strip chips off the flip push rod, and the upper extrusion roller cleans the strip chips on the flip push rod every time it rotates one circle, thereby realizing timely cleaning of the strip chips wrapped around the flip push rod, which can effectively prevent the strip chips on the upper extrusion roller from becoming more and more entangled, ensure the normal rotation of the upper extrusion roller, and improve the extrusion efficiency of the upper extrusion roller for chips.

[0012] In order to be able to replace the front roller body, the middle roller body and the rear roller body separately, the front roller body and the middle roller body, the two adjacent middle roller bodies, and the middle roller body and the rear roller body cannot be connected in a fixed manner. Under the premise of not adopting a fixed manner, it is necessary to ensure that the front roller body, the middle roller body and the rear roller body rotate coaxially and synchronously. Therefore, a connecting rod is vertically fixedly installed on the rear end face of the front roller body, and several of the connecting rods are evenly distributed along the circumference of the central axis of the front roller body. Several of the middle roller bodies are provided with connecting through holes, and several of the connecting through holes are arranged in one-to-one correspondence with several connecting rods. A connecting blind hole is opened on the front end face of the rear roller body, and several of the connecting blind holes are arranged in one-to-one correspondence with several connecting rods. The connecting rods pass through several connecting through holes in turn and are inserted into the connecting blind holes.

[0013] In order to reduce the friction between the flip push rod and the cam and also to facilitate the flip push rod to insert into the chip mass, both ends of the flip push rod are spherical surfaces.

[0014] In order to better fix the cam, the height of the cam is equal to the height of the accommodating cavity.

[0015] Preferably, the elastic element is a compression spring.

[0016] In order to make the lower squeezing roller more convenient to move the chips between the two lower squeezing rollers, the friction between the lower squeezing roller and the chips needs to be increased, and a plurality of anti-slip protrusions are arranged on the outer circumferential surface of the lower squeezing roller.

[0017] In order to achieve that the inner rotating shaft is fixedly installed on the casing while the outer rotating shaft sleeved outside the inner rotating shaft can be rotatably installed on the casing, a mounting bracket is fixedly installed on the casing, and the two mounting brackets are respectively located at the two ends of the inner rotating shaft. Both ends of the inner rotating shaft extend out of the outer rotating shaft and are fixedly connected to the mounting brackets.

[0018] Furthermore, the rotating mechanism has two groups, each group of the rotating mechanism simultaneously drives the upper extrusion roller and the lower extrusion roller on the same side, and each group of the rotating mechanism includes a motor, a driving pulley, a first driven pulley, a second driven pulley and a third driven pulley, the driving pulley is fixedly mounted on the output end of the motor, the first driven pulley and the second driven pulley are both fixedly mounted on the outer rotating shaft, the third driven pulley is coaxially fixedly connected to the lower extrusion roller, the driving pulley is connected to the first driven pulley through a first synchronous belt transmission, the second driven pulley is connected to the third driven pulley through a second synchronous belt transmission, and the motors in the two groups of the rotating mechanisms are a group of synchronous motors, and have the same rotation direction.

[0019] In order to facilitate the discharge of chips, a guide plate is fixedly installed below the lower extrusion assembly in the housing, and the two guide plates are arranged in a V shape, and the gap between the lower ends of the two guide plates is an extrusion outlet. Both ends of the flip push rod are spherical surfaces.

[0020] The beneficial effects of the present invention are as follows: when the chip removal and extrusion integrated machine for machine tools of the present invention is in use, the chips cut off from the machine tool enter the shell from the chip inlet, are transported to the chip outlet through the conveying assembly in the shell, and the chips fall into the extrusion inlet from the chip outlet. An upper extrusion assembly is rotatably installed on the upper end of the inner part of the shell, and a lower extrusion assembly is rotatably installed on the lower end of the inner part. The upper extrusion assembly includes an upper extrusion roller, and a flip push rod with a protruding roller body is retractably provided on the upper extrusion roller. The two upper extrusion rollers are located at the same height, and the two upper extrusion rollers are parallel and spaced apart. The rotating mechanism drives the two upper extrusion rollers to rotate relative to each other, and at the same time drives the two lower extrusion rollers to rotate relative to each other. The chips move between the two upper extrusion rollers driven by the flip push rod. After the chips are squeezed by the two upper extrusion rollers, their volume is reduced. One side of the two upper extrusion rollers is in contact with the inner wall of the shell, and the chips cannot pass between the upper extrusion roller and the shell, but can only pass between the two upper extrusion rollers, so that all chips can be removed. The chips are squeezed; the chips squeezed by the upper squeezing roller move between the two lower squeezing rollers under the action of the lower squeezing roller. Since the gap between the two lower squeezing rollers is smaller than the gap between the two upper squeezing rollers, the two lower squeezing rollers can further squeeze the chips, further reducing the volume of the chips. At the same time, the chips are squeezed and compressed together, which is also convenient for cleaning, thereby improving the chip cleaning efficiency; one side of the two lower squeezing rollers is in contact with the inner wall of the casing, and the chips cannot pass between the lower squeezing roller and the casing, but can only pass between the two lower squeezing rollers, so that all the chips can be squeezed; a flip push rod protruding from the roller body is retractably provided on the upper squeezing roller, and the strip chips wrapped on the flip push rod can be scraped off during the process of the push rod being retracted into the upper squeezing roller, and the strip chips on the flip push rod are cleaned once the upper squeezing roller rotates one circle, thereby realizing timely cleaning of the strip chips wrapped on the flip push rod without stopping the rotation of the upper squeezing roller.

[0039] The rotating mechanism drives the two upper squeezing rollers 4 to rotate relative to each other, and at the same time drives the two lower squeezing rollers 5 to rotate relative to each other.

[0040] The upper squeezing roller 4 includes an inner rotating shaft 4-2, which is fixedly mounted on the casing 3, and a front roller body 4-3, a middle roller body 4-4 and a rear roller body 4-5 are rotatably mounted on the inner rotating shaft 4-2. The front roller body 4-3 and the rear roller body 4-5 are both coaxially fixedly mounted with an outer rotating shaft 4-6, and the two outer rotating shafts 4-6 are both rotatably mounted on the casing 3. The rear end surface of the front roller body 4-3, the front and rear end surfaces of the middle roller body 4-4, and the front end surface of the rear roller body 4-5 are coaxially provided with a receiving groove 4-7. The outer circumference of the front roller body 4-3, the middle roller body 4-4 and the rear roller body 4-5 is An even number of limiting openings 4-8 connected to the accommodating grooves 4-7 are uniformly opened on the surface circumferentially. The middle roller body 4-4 has multiple, and the front roller body 4-3, multiple middle roller bodies 4-4, and the rear roller body 4-5 are sequentially fitted from front to back. After the front roller body 4-3 is fitted with the adjacent middle roller body 4-4, after the two adjacent middle roller bodies 4-4 are fitted, after the rear roller body 4-5 is fitted with the adjacent middle roller body 4-4, the two opposite accommodating grooves 4-7 are pieced together to form an accommodating cavity, and the two opposite limiting openings 4-8 are pieced together to form a limiting through hole.

The inner ends of the flip push rods 4-1 in the limiting through holes connected to the same accommodating cavity are all connected to the outer periphery of the cam 4-10. When the flip push rods 4-1 in the two upper squeezing rollers 4 are arranged opposite to each other, the flip push rod 4-1 extending out of the limiting through hole has the longest length, which is the longest flip push rod 4-1; on the same upper squeezing roller 4, the flip push rod 4-1 directly opposite to the longest flip push rod 4-1 is the shortest flip push rod 4-1, and the shortest flip push rod 4-1 is completely received in the limiting through hole. During the rotation of the upper squeezing roller 4, several of the flip push rods 4-1 on the same circumference are gradually changed from the longest flip push rod 4-1 to the shortest flip push rod 4-1, and then gradually changed from the shortest flip push rod 4-1 to the longest flip push rod 4-1.In order to be able to replace the front roller body 4-3, the middle roller body 4-4 and the rear roller body 4-5 separately, the front roller body 4-3 and the middle roller body 4-4, the two adjacent middle roller bodies 4-4, and the middle roller body 4-4 and the rear roller body 4-5 cannot be connected in a fixed manner. Under the premise of not adopting a fixed manner, it is necessary to ensure that the front roller body 4-3, the middle roller body 4-4 and the rear roller body 4-5 rotate coaxially and synchronously. Therefore, a connecting rod 4-11 is vertically fixedly installed on the rear end face of the front roller body 4-3, and several of the connecting rods 4-11 are evenly distributed along the circumference of the central axis of the front roller body 4-3. Several of the middle roller bodies 4-4 are provided with connecting through holes, and several of the connecting through holes are arranged in a one-to-one correspondence with several connecting rods 4-11. A connecting blind hole is opened on the front end face of the rear roller body 4-5, and several of the connecting blind holes are arranged in a one-to-one correspondence with several connecting rods 4-11. The connecting rod 4-11 passes through several connecting through holes in turn and is inserted into the connecting blind hole.

[0041] A mounting bracket 6 is fixedly mounted on the housing 3. Two mounting brackets 6 are respectively located at the two ends of the inner rotating shaft 4-2. Both ends of the inner rotating shaft 4-2 extend out of the outer rotating shaft 4-6 and are fixedly connected to the mounting brackets 6.

[0042] The rotating mechanism has two groups, each group of the rotating mechanism simultaneously drives the upper extrusion roller 4 and the lower extrusion roller 5 on the same side, each group of the rotating mechanism includes a motor 7, a driving pulley 8, a first driven pulley 9, a second driven pulley 10 and a third driven pulley 11, the driving pulley 8 is fixedly mounted on the output end of the motor 7, the first driven pulley 9 and the second driven pulley 10 are both fixedly mounted on the outer rotating shaft 4-6, the third driven pulley 11 is coaxially fixedly connected with the lower extrusion roller 5, the driving pulley 8 is connected to the first driven pulley 9 through a first synchronous belt 12, the second driven pulley 10 is connected to the third driven pulley 11 through a second synchronous belt 13, and the motors 7 in the two groups of the rotating mechanisms are a group of synchronous motors 7, and the rotation directions are the same.

[0043] A guide plate 14 is fixedly installed below the lower extrusion assembly in the housing 3. The two guide plates 14 are arranged in a V shape, and the gap between the lower ends of the two guide plates 14 is the extrusion outlet 3-2. Both ends of the flip push rod 4-1 are spherical surfaces.

[0044] The chip removal and extrusion integrated machine for machine tools of the present invention, when in use, the chips cut off the machine tool enter the shell body 1 from the chip inlet 1-1, are transported to the chip outlet 1-2 through the conveying assembly 2 in the shell body 1, and the chips fall into the extrusion inlet 3-1 from the chip outlet 1-2. The upper end of the inner part of the shell body 3 is rotatably installed with an upper extrusion assembly, and the lower end of the inner part is rotatably installed with a lower extrusion assembly. The upper extrusion assembly includes an upper extrusion roller 4, and a retractable flip push rod 4-1 protruding from the roller body is provided on the upper extrusion roller 4. The two upper extrusion rollers 4 are located at the same height, and the two upper extrusion rollers 4 are parallel and spaced apart. The rotating mechanism drives the two upper extrusion rollers 4 to rotate relative to each other, and at the same time drives the two lower extrusion rollers 5 to rotate relative to each other. The chips move between the two upper extrusion rollers 4 driven by the flip push rod 4-1. After the chips are extruded by the two upper extrusion rollers 4, the volume The chips are reduced in size, one side of the two upper squeezing rollers 4 is in contact with the inner wall of the casing 3, and the chips cannot pass between the upper squeezing rollers 4 and the casing 3, but can only pass between the two upper squeezing rollers 4, so that all the chips can be squeezed; the chips squeezed by the upper squeezing rollers 4 move to between the two lower squeezing rollers 5 under the action of the lower squeezing rollers 5, and because the gap between the two lower squeezing rollers 5 is smaller than the gap between the two upper squeezing rollers 4, the two lower squeezing rollers 5 can further squeeze the chips, further reducing the volume of the chips, and at the same time, the chips are squeezed and compressed together, which is also convenient for cleaning, thereby improving the chip cleaning efficiency; one side of the two lower squeezing rollers 5 is in contact with the inner wall of the casing 3, and the chips cannot pass between the lower squeezing rollers 5 and the casing 3, but can only pass between the two lower squeezing rollers 5, so that all the chips can be squeezed;Since the chips are in the form of strips, the strip chips are easily entangled on the flip push rod 4-1 during the rotation of the upper extrusion roller 4. If the strip chips wrapped around the flip push rod 4-1 are not cleaned in time, the strip chips on the upper extrusion roller 4 will become more and more entangled, which will affect the rotation of the upper extrusion roller 4 and the extrusion efficiency of the cutting. If the rotation of the upper extrusion roller 4 is stopped regularly to clean the upper extrusion roller 4, the efficiency of extruding the chips of the present invention is low. Therefore, it is necessary to clean the strip chips wrapped around the flip push rod 4-1 in time when the upper extrusion roller 4 does not stop rotating. Therefore, the upper extrusion roller 4 is telescopically provided with a flip push rod 4-1 with a protruding roller body. If strip chips are wrapped around the flip push rod 4-1, during the rotation of the front roller body 4-3, the middle roller body 4-4 and the rear roller body 4-5, the cam 4-10 does not rotate, and the front roller body 4-3, the middle roller body 4-4 and the rear roller body 4-5 The flip push rod 4-1 rotates around the central axis of the front roller body 4-3. During the rotation, the flip push rod 4-1 always fits with the outer peripheral surface of the cam 4-10. The flip push rod 4-1 gradually changes from the longest flip push rod 4-1 to the shortest flip push rod 4-1. The flip push rod 4-1 gradually shrinks into the guide hole. Since the radius of the guide hole is equal to the radius of the flip push rod 4-1, when the flip push rod 4-1 shrinks into the guide hole, the outer peripheral surfaces of the front roller body 4-3, the middle roller body 4-4 and the rear roller body 4-5 scrape the strip chips from the flip push rod 4-1. The upper squeeze roller 4 cleans the strip chips on the flip push rod 4-1 once every rotation, thereby realizing timely cleaning of the strip chips wrapped around the flip push rod 4-1, effectively preventing the strip chips on the upper squeeze roller 4 from becoming more and more entangled, ensuring the normal rotation of the upper squeeze roller 4, and improving the squeezing efficiency of the upper squeeze roller 4 on the chips. ;

The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
