[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figures 1 to 8 , the present invention provides a technical solution:

[0035] A waste chip cleaning device for CNC machine tool processing, comprising a machine tool platform 3, a control console 2 fixed to the left side of the upper end surface of the machine tool platform 3 and a cabinet 1 fixed to the machine tool platform 3, the lower end surface of the cabinet 1 is provided with an automatic turning part 6, the right end surface of the control console 2 is provided with a driving fixture 5, the upper end surface of the machine tool platform 3 is provided with a cleaning mechanism 8, and the front end surface of the machine tool platform 3 is fixed with a motor 4;

[0036] The cleaning mechanism 8 includes a collecting tank 31 provided on the machine tool platform 3, the bottom of the collecting tank 31 is open and a collecting box 32 is magnetically mounted thereon, a filter screen 33 is provided on the top of the collecting box 32, and the filter screen 33 is fixed to the inner wall of the collecting tank 31 by bolts;

[0037] The collecting tank 31 is symmetrically provided with a conveyor belt 81 inside, and the conveyor belt 81 is movably connected to the collecting tank 31 . The two conveyor belts 81 are designed to be inclined relative to each other, and the conveyor belt 81 is made of elastic alloy metal material with a hollow structure design on the surface.

[0038] Specifically, the cleaning mechanism 8 includes a winding drum 83 symmetrically arranged in the middle position inside the collecting groove 31, and the two ends of the winding drum 83 are rotatably connected to the inner wall of the collecting groove 31, and a rotating groove 84 is opened inside the machine tool platform 3 in the upper area of ​​the opening of the collecting groove 31, and a winding drum 89 is rotatably connected inside the rotating groove 84, and a connecting groove is opened between the rotating groove 84 and the collecting groove 31.

[0039] Preferably, one end of the conveyor belt 81 is fixed to the take-up drum 1 83, and the other end is wound around the outside of the take-up drum 2 89 through a connecting groove and fixedly connected to the take-up drum 2 89. Both ends of the take-up drum 2 89 are fixed with a rotating shaft, and a coil spring 891 is sleeved on the outside of the rotating shaft, one end of the coil spring 891 is fixed to the rotating shaft, and the other end is fixed to the inner wall of the rotating groove 84. The take-up drum 2 89 is rotatably connected to the inner wall of the rotating groove 84 through the rotating shaft, and the upper end surface of the conveyor belt 81 is fixedly connected to a limiting plate 85, and the limiting plate 85 is made of rubber material. Gears 86 are fixedly connected to the shaft rods at both ends of the two take-up drums 1 83, and the two gears 86 are meshedly connected. A connecting shaft 87 is fixed to the front end shaft rod of one of the take-up drums 1 83, and the front end of the connecting shaft 87 is fixed to the output shaft of the motor 4. A transmission shaft 88 is fixedly connected to the rear end shaft rod of one of the take-up drums 1 83, and the transmission shaft 88 is transmission connected to the cleaning structure 7.

[0040] By adopting the above technical solution, the metal workpiece is fixed by the driving fixture 5, and the metal workpiece is turned by the automatic turning part 6 under the control of the control console 2. The metal iron filings dropped during the processing fall through the top opening of the collecting tank 31 to the surface of the conveyor belt 81 for temporary storage. As the metal workpiece is processed, more metal iron filings are accumulated, and the metal workpiece will fall mixed with cutting fluid during the processing. At this time, the conveyor belt 81 is used to filter the metal iron filings and cutting fluid that fall together through the conveyor belt 81 and the stacked metal iron filings. The filtered cutting fluid falls and is filtered again through the filter screen 33 into the collection box 32.

[0041] When a certain amount of iron filings accumulate on the conveyor belt 81 in the collecting tank 31, the user controls the motor 4 to operate, and the motor 4 drives the connecting shaft 87 to rotate, and further drives the winding drum 83 to rotate. At this time, under the meshing of the gear 86, the two winding drums 83 rotate towards each other to wind up the conveyor belt 81. At this time, the iron filings on the conveyor belt 81 move downward under the transmission of the conveyor belt 81. When the iron filings pass through the two winding drums 83, the fluffy metal iron filings are squeezed into blocks or sheets and fall downward to the surface of the filter screen 33, so as to facilitate the subsequent collection and processing by the user, thereby improving the storage capacity of the metal iron filings and the subsequent processing efficiency of the metal iron filings;

[0042] During the operation of the conveyor belt 81, the limit plate moves together. The function of the limit plate is to carry the metal iron chips downward to prevent the metal iron chips from being squeezed and splashed. During the operation of the conveyor belt 81, the take-up drum 89 rotates to loosen the conveyor belt 81, and the winding spring 891 accumulates momentum. When the subsequent motor 4 reverses and the conveyor belt 81 is reset, the take-up drum 89 is driven to rotate in the direction of the winding spring 891 to rewind and reset the conveyor belt 81.

[0043] Specifically, a cleaning piece 82 is provided on the lower side of the conveyor belt 81, and the cleaning piece 82 is in contact with the lower end surface of the conveyor belt 81, and the cleaning piece 82 is connected to the cleaning structure 7, and the cleaning structure 7 includes a sealing cylinder 71 fixed to the rear end surface of the machine tool platform 3 and the corresponding position of the transmission shaft 88, and the interior of the sealing cylinder 71 is rotatably connected with a threaded rod 74, and the front end of the threaded rod 74 is fixed to the transmission shaft 88, and a piston plate 75 is provided inside the sealing cylinder 71, and the piston plate 75 is connected to the threaded rod 74 in a spiral transmission manner, and the rear side of the outer surface of the sealing cylinder 71 is respectively provided with a water suction interface 72 and a water outlet interface 73, and the water suction interface One-way valves are built into the water outlet interface 72, and the external pipe of the water intake interface 72 is connected to the external water supply equipment, and the water outlet interface 73 is connected to the cleaning component 82 through a pipe. The cleaning component 82 includes a fixed plate 824 with a U-shaped structure design, and elastic paddles 821 are fixed at equal distances on one side of the upper end surface of the fixed plate 824, and the position of the elastic paddles 821 corresponds to the hollow mesh on the surface of the conveyor belt 81, and a nozzle 822 is embedded on the other side of the upper end surface of the fixed plate 824. A water trough 823 is provided in the fixed plate 824, and the water trough 823 is connected to the nozzle 822, and the other end of the water trough 823 is connected to the water outlet interface 73 pipe.

[0044] By adopting the above technical solution, during the process of filtering iron chips and cutting fluid, the hollow mesh of the conveyor belt 81 may be attached with impurities or blocked with iron chips. Therefore, when the conveyor belt 81 contacts the elastic paddle 821 on the fixed plate 824 during transportation, the elastic paddle 821 compresses and accumulates elasticity, and then plugs into the hollow mesh of the conveyor belt 81 to remove the impurities attached inside, thereby avoiding clogging of the conveyor belt 81.

[0045] Moreover, during the process of driving the winding drum 83 to rotate, the motor 4 drives the threaded rod 74 in the sealing cylinder 71 to rotate through the transmission shaft 88, and further drives the piston plate 75 to rotate. The threaded rod 74 is a kind of reciprocating screw. Therefore, the piston plate 75 can move back and forth inside the sealing cylinder 71 to draw water from the external water source through the water suction interface 72, and then transport it to the water tank 823 in the fixed plate 824 through the water outlet interface 73 and the pipeline, and finally spray it on the surface of the conveyor belt 81 through the nozzle 822, so as to further clean the conveyor belt 81 and maintain the cleanliness of the conveyor belt 81.

[0046] Working principle: The metal workpiece is fixed by the driving fixture 5, and the metal workpiece is turned by the automatic turning part 6 under the control of the control console 2. The metal iron chips dropped during the processing fall through the top opening of the collecting tank 31 to the surface of the conveyor belt 81 for temporary storage. As the metal workpiece is processed, more metal iron chips are accumulated, and the metal workpiece will fall mixed with cutting fluid during the processing. At this time, the conveyor belt 81 is used to filter the metal iron chips and cutting fluid that fall together through the conveyor belt 81 and the stacked metal iron chips. The filtered cutting fluid falls and is filtered again through the filter screen 33 into the collection box 32;

[0047] When a certain amount of iron filings accumulate on the conveyor belt 81 in the collecting tank 31, the user controls the motor 4 to operate, and the motor 4 drives the connecting shaft 87 to rotate, and further drives the winding drum 83 to rotate. At this time, under the meshing of the gear 86, the two winding drums 83 rotate towards each other to wind up the conveyor belt 81. At this time, the iron filings on the conveyor belt 81 move downward under the transmission of the conveyor belt 81. When the iron filings pass through the two winding drums 83, the fluffy metal iron filings are squeezed into blocks or sheets and fall downward to the surface of the filter screen 33, so as to facilitate the subsequent collection and processing by the user, thereby improving the storage capacity of the metal iron filings and the subsequent processing efficiency of the metal iron filings;

[0048] During the operation of the conveyor belt 81, the limit plate moves together. The function of the limit plate is to move the metal iron chips downward to prevent the metal iron chips from being squeezed and splashed. During the operation of the conveyor belt 81, the reel 89 rotates to loosen the conveyor belt 81, and the coil spring 891 accumulates power. When the motor 4 reverses and the conveyor belt 81 is reset, the reel 89 is driven by the coil spring 891 to rotate and rewind the conveyor belt 81.

[0049] During the filtering process of iron chips and cutting fluid, the hollow mesh of the conveyor belt 81 may be attached with impurities or blocked with iron chips. Therefore, when the conveyor belt 81 contacts the elastic paddle 821 on the fixed plate 824 during the conveying process, the elastic paddle 821 compresses and accumulates elasticity, and then plugs into the hollow mesh of the conveyor belt 81 to remove the impurities attached inside, thereby avoiding clogging of the conveyor belt 81.

[0050] Moreover, during the process of driving the winding drum 83 to rotate, the motor 4 drives the threaded rod 74 in the sealing cylinder 71 to rotate through the transmission shaft 88, and further drives the piston plate 75 to rotate. The threaded rod 74 is a kind of reciprocating screw. Therefore, the piston plate 75 can move back and forth inside the sealing cylinder 71 to draw water from the external water source through the water suction interface 72, and then transport it to the water tank 823 in the fixed plate 824 through the water outlet interface 73 and the pipeline, and finally spray it on the surface of the conveyor belt 81 through the nozzle 822, so as to further clean the conveyor belt 81 and maintain the cleanliness of the conveyor belt 81.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
