Description

Technical Field

[0001] The utility model relates to the technical field of waste chip recovery devices, in particular to a CNC machining waste chip recovery device. Background Art

[0002] CNC (Computer Numerical Control) is a technology that uses computer programs to control mechanical equipment for automatic processing. It is widely used in the manufacturing industry, especially in the fields of metal, wood and plastic processing. CNC technology has high precision, high efficiency and excellent repeatability. Through computer programming, manufacturers can easily adjust production tasks and quickly adapt to different product needs, thereby improving production flexibility. During the CNC processing process, a large amount of waste chips will be generated, which will accumulate on the processing table. At this time, a waste chip recovery device is needed to recycle it.

[0003] CNC waste chip recovery devices can efficiently and safely collect waste materials such as metal chips, wood chips, and plastic debris, and recycle used cutting fluid to reduce pollution to the environment and improve resource utilization. However, there are still certain problems: when CNC equipment is processed, chain plate chip conveyors are mostly used to recycle processing waste chips, but the waste chips generated when processing different materials are of different sizes and shapes, and it is impossible to carry out targeted recycling of different waste chips. Incomplete waste chip recovery can easily cause damage to the reflux pump, and the recovered waste chips contain a large amount of cutting fluid, resulting in waste of cutting fluid and environmental pollution. Therefore, in view of the above situation, there is an urgent need to develop a CNC processing waste chip recovery device to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0004] The purpose of the present invention is to provide a CNC machining waste chip recovery device to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a CNC machining waste chip recovery device, comprising a filter frame, a chain conveyor belt, and a centrifugal separation mechanism, wherein the chain conveyor belt is detachably mounted on the top edge of the filter frame, the centrifugal separation mechanism is located on one side of the chain conveyor belt, and the discharge end of the chain conveyor belt extends to the interior of the centrifugal separation mechanism through a trough, and a reduction motor for driving the chain conveyor belt is mounted on one side of the chain conveyor belt;

[0006] A partition a is fixed inside the filter frame, and multiple partitions b are fixed between the partition a and the inner wall of the filter frame. Multiple filter cavities are formed between the multiple partitions b, the partition a and the filter frame. Multiple groups of brushes are installed in the filter cavity, and a conical sedimentation frame is embedded in the bottom of the filter cavity.

[0007] The centrifugal separation mechanism includes an outer cylinder, a base, a separation cylinder, a motor, a driven wheel and a discharge pipe. The outer cylinder is fixedly arranged on the top of the base at an angle, the separation cylinder is rotatably installed inside the outer cylinder, the motor is fixed on the outer wall of the outer cylinder, the end of the output shaft of the motor is sleeved with a driving wheel, the driven wheel is sleeved on the outer wall of the bottom end of the separation cylinder, a transmission belt is sleeved between the driven wheel and the driving wheel for transmission, and the discharge pipe is passed through the bottom of the outer cylinder.

[0008] Preferably, partition a divides the filter frame into two independent chambers, one of which is used to receive the cutting fluid filtered out from the chain conveyor belt, and the other chamber cooperates with partition b to form several filter chambers connected in sequence. Specifically, a conducting groove is provided on the upper side of one side of partition a, and the cutting fluid can enter the filter chamber at the outermost edge through the conducting groove. Conducting grooves are provided on multiple partitions b, and the conducting grooves on multiple partitions b are staggered one above and one below. Multiple groups of filter chambers are connected in series through the conducting grooves to form an "S"-shaped conducting path.

[0009] Preferably, a hanging rod is provided above the brush, and both ends of the hanging rod are mounted on the edges of the filter frame and partition a, and the top ends of multiple groups of brushes are mounted on the hanging rod. Specifically, the provided brushes can slow down the flow rate of the cutting fluid, causing the fine processing waste chips in the cutting fluid to settle to the bottom of the conical sedimentation frame, or adhere to the brush, to avoid damage caused by the subsequent reflux pump.

[0010] Preferably, the bottom of the conical sedimentation frame is detachably connected to a plurality of magnets. Specifically, the magnets can attract magnetically attracted processing waste to the bottom of the conical sedimentation frame to promote sedimentation.

[0011] Preferably, a number of equally spaced through holes are provided inside the separation cylinder. Specifically, during high-speed rotation of the separation cylinder, the cutting fluid attached to the waste chips can be discharged into the inner wall of the outer cylinder through the through holes by centrifugal force, thereby separating the waste chips and the cutting fluid.

[0012] Preferably, a sealing ring is installed between the separation cylinder and the inner wall of the outer cylinder. Specifically, the sealing ring can intercept the cutting fluid on the outer wall of the separation cylinder, gather it into the outer cylinder, and finally discharge it through the drain pipe.

[0013] Compared with the prior art, the present invention provides a CNC machining waste chip recovery device with the following beneficial effects:

[0014] The chain conveyor is used to uniformly recycle and filter the discharged cutting fluid and waste chips. The large particles of waste chips will be transported to the centrifugal separation mechanism through the chain conveyor for subsequent centrifugal separation treatment, and the cutting fluid attached to the waste chips will be separated and treated as completely as possible, thereby improving the utilization rate of the cutting fluid and avoiding environmental pollution. The fine waste chips that enter the filter frame with the cutting fluid through the chain conveyor need to pass through multiple filter chambers composed of partitions a and partitions b in turn. Each filter chamber is equipped with a brush, which, combined with its "S"-shaped flow path, can promote most of the fine waste chips to settle to the bottom of the conical sedimentation frame or adhere to the brush, preventing them from entering the subsequent reflux pump, thereby achieving low-cost and high-efficiency filtration.

[0027] A partition a101 is fixedly installed inside the filter frame 10. A plurality of partitions b102 are fixedly installed between the partition a101 and the inner wall of the filter frame 10.

[0028] The centrifugal separation mechanism 30 includes an outer cylinder 301, a base 302, a separation cylinder 303, a motor 304, a driven wheel 307 and a discharge pipe 309. The outer cylinder 301 is fixedly arranged on the top of the base 302 at an angle, the separation cylinder 303 is rotatably installed inside the outer cylinder 301, the motor 304 is fixedly arranged on the outer wall of the outer cylinder 301, the end of the output shaft of the motor 304 is sleeved with a driving wheel 305, the driven wheel 307 is sleeved on the outer wall of the bottom end of the separation cylinder 303, a transmission belt 306 for transmission is sleeved between the driven wheel 307 and the driving wheel 305, and the discharge pipe 309 is passed through the bottom of the outer cylinder 301.

[0029] Preferably, the partition a101 divides the filter frame 10 into two independent chambers, one of which is used to receive the cutting fluid filtered out from the chain conveyor 20, and the other chamber cooperates with the partition b102 to form a number of filter chambers connected in sequence. Specifically, a conducting groove is provided on the upper side of one side of the partition a101, and the cutting fluid can enter the filter chamber at the outermost edge through the conducting groove. Conducting grooves are provided on multiple partitions b102, and the conducting grooves on multiple partitions b102 are staggered one above and one below. Multiple groups of filter chambers are connected in series through the conducting grooves to form an "S"-shaped conducting path.

[0030] Preferably, a hanging rod 105 is provided above the brush 103, and both ends of the hanging rod 105 are mounted on the edges of the filter frame 10 and the partition a101, and the top ends of multiple groups of brushes 103 are mounted on the hanging rod 105. Specifically, the provided brushes 103 can slow down the flow rate of the cutting fluid, causing the fine processing waste chips in the cutting fluid to settle to the bottom of the conical sedimentation frame 104, or adhere to the brush 103, to avoid damage caused by the subsequent reflux pump.

[0031] Preferably, a plurality of magnets 106 are detachably connected to the bottom of the conical sedimentation frame 104. Specifically, the magnets 106 can attract magnetically attracted processing waste to the bottom of the conical sedimentation frame 104 to promote sedimentation.

[0032] Preferably, a number of equally spaced through holes are provided inside the separation cylinder 303. Specifically, during the high-speed rotation of the separation cylinder 303, the centrifugal force can be used to discharge the cutting fluid attached to the waste chips through the through holes into the inner wall of the outer cylinder 301, thereby achieving separation of the waste chips and the cutting fluid.

[0033] Preferably, a sealing ring 308 is installed between the separation cylinder 303 and the inner wall of the outer cylinder 301. Specifically, the sealing ring 308 can intercept the cutting fluid on the outer wall of the separation cylinder 303 and make it converge into the outer cylinder 301 and finally be discharged through the drain pipe 309.

[0034] Working principle: The waste chips generated during CNC equipment processing will be discharged onto the chain conveyor 20 along with the cutting fluid. The cutting fluid and some fine waste chips will fall into the filter frame 10 through the chain conveyor 20, and the large particles of waste chips will be transported by the chain conveyor 20 to the separation cylinder 303 of the centrifugal separation mechanism 30. The motor 304 cooperates with the driving wheel 305 and the transmission belt 306 to drive the driven wheel 307 and the separation cylinder 303 to rotate at high speed. The centrifugal force generated by the high-speed rotation is used to separate the cutting fluid attached to the surface of the waste chips. The separated cutting fluid will pass through the through hole of the separation cylinder 303 into the inner wall of the outer cylinder 301, and finally be discharged through the bottom drain pipe 309, collected and filtered for recycling, and the large particles of waste chips that have been filtered out of the cutting fluid will be discharged through the bottom of the separation cylinder 303. The cutting fluid in the filter frame 10 gathers to a certain liquid level. When the cutting fluid is in contact with the brush 103 over a large area, the cutting fluid will gradually settle and adsorb the fine waste chips to achieve a high-efficiency filtration effect. When the cutting fluid reaches the rightmost chamber, the filtration degree is extremely high. A reflux pump and filter cotton are installed in the rightmost chamber to return the cutting fluid for use. It should be noted that a magnet is installed at the bottom of the conical sedimentation frame 104. When filtering magnetically attractive metal waste chips, they can be adsorbed to promote precipitation. At the same time, the materials of the entire filtration process can be reused, reducing the subsequent use cost and the manufacturing cost.
