Description

Technical Field

[0001] This utility model belongs to the technical field of CNC machining equipment, and in particular relates to a waste cleaning and recycling device for CNC machining centers. Background Technology

[0002] A CNC machining center is a high-efficiency automated machine tool composed of mechanical equipment and a CNC system, suitable for machining complex parts. Various waste materials are generated during CNC machining, which need to be cleaned and recycled promptly.

[0003] Chinese utility model patent application number 202120156845.5 discloses a waste cleaning and recycling device for CNC machining centers. The device includes a CNC machining center body with a discharge bin at its bottom. A magnetic suction plate is located on one side of the discharge bin, and a corrugated pipe is located on the side of the magnetic suction plate away from the CNC machining center body. A recycling bin is located on the side of the corrugated pipe away from the magnetic suction plate. This utility model uses a filter screen to screen the waste, with large ferrous metal waste particles remaining on the filter screen. When an electromagnet is energized, it generates magnetic attraction, attracting the ferrous waste particles from the filter screen below. Then, a servo motor, via a lead screw and nut, moves a fixed cover and the electromagnet through a movable slot on the recycling bin to the top of the collection bin. When the electromagnet is de-energized, the attracted ferrous waste falls into the collection bin, effectively solving the waste screening problem.

[0004] However, the aforementioned utility model patents still have some shortcomings:

[0005] In the process of using the above-mentioned utility model patent, large-particle ferrous metal waste is filtered through a filter screen, and then adsorbed and transferred by an electromagnet plate above the filter screen. When the waste enters the recycling bin through the corrugated pipe, it will accumulate at the inlet of the corrugated pipe. This means that the ferrous metal waste can be adsorbed at the position of the electromagnet plate near the corrugated pipe, while other areas cannot effectively adsorb the ferrous metal waste due to the greater distance, resulting in low adsorption and screening efficiency.

[0006] Furthermore, the electromagnet plate does not immediately demagnetize after the power is turned off, which results in some small iron metal waste particles being adsorbed on the electromagnet plate. This waste will occupy the adsorption space on the electromagnet plate. Utility Model Content

[0007] This utility model provides a waste cleaning and recycling device for CNC machining centers, which aims to solve the problems mentioned in the background art.

[0008] This utility model is implemented as follows: a waste cleaning and recycling device for CNC machining centers includes a recycling bin, with casters installed at the bottom of the recycling bin. A channel opening is provided on the side wall of the recycling bin, and a guide docking plate is obliquely fixed to the channel opening. The internal space of the recycling bin is divided into two spaces by a partition, with a collection bin one and a collection bin two placed in each space. A conveying assembly is connected to the oblique lower end of the guide docking plate. The conveying assembly is installed on the inner wall of the recycling bin, and the collection bin one is located below the conveying assembly. A moving mechanism is installed above the conveying assembly and on the inner wall of the recycling bin. An electromagnet plate is installed at the moving end of the moving mechanism, and a cleaning component is located below the moving path of the electromagnet plate.

[0009] Preferably, the conveying assembly includes conveying rollers arranged opposite each other, both ends of which are rotatably mounted between the front and rear walls of the recycling bin via rotating rods. One of the rotating rods passes through the side wall of the recycling bin and is connected to the output shaft of the motor. A conveyor belt is driven between the conveying rollers, and a brush is fixedly attached below the conveyor belt and to the inner wall of the recycling bin.

[0010] Preferably, the cleaning assembly includes a connecting rod, which is rotatably mounted on the inner wall of the recycling bin. A sleeve is fitted onto the side wall of the connecting rod, and a second brush is fixedly connected to the side wall of the sleeve.

[0011] Preferably, an actuating rod one is vertically fixed to the rear side of the sleeve and on the curved side wall of the connecting rod; an adjusting rod one is fixed to the rear wall of the electromagnet plate at a position away from the actuating rod one; an actuating rod two is horizontally fixed to the front side of the sleeve and on the curved side wall of the connecting rod; and an adjusting rod two is fixed to the front wall of the electromagnet plate at a position close to the actuating rod two.

[0012] Preferably, button 2 and button 1 are respectively installed on the left and right side walls of the electromagnet plate mounting box. A trigger button 1 is installed on the right inner wall of the recycling box at a position opposite to button 1 via an extension column 1. A trigger button 2 is installed on the left inner wall of the recycling box at a position opposite to button 2 via an extension column 2. A controller is installed on the outer wall of the recycling box. The controller is connected to trigger button 1, trigger button 2, the drive end of the moving mechanism, and the motor via wiring.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By using a motor-controlled conveyor belt to transport the waste, the ferrous metal waste can be gradually and evenly adsorbed onto the bottom of the electromagnet plate, thereby improving the adsorption efficiency of the electromagnet plate.

[0015] By cooperating with the trigger rod and the adjusting rod, the second brush can clean the ferrous metal waste that is still adsorbed on the bottom of the electromagnet plate after the power is turned off, thereby further improving the adsorption efficiency of the electromagnet plate.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Please see Figure 1-3 This utility model provides a technical solution: a waste cleaning and recycling device for CNC machining centers, including a recycling box 1, with a moving wheel 22 installed at the bottom of the recycling box 1, a channel opening 2 on the side wall of the recycling box 1, and a guide docking plate 3 fixedly connected at an incline at the channel opening 2. The internal space of the recycling box 1 is divided into two spaces by a partition 10, and a collection box 8 and a collection box 11 are placed in the two spaces respectively.

[0027] The guide docking plate 3 is connected to the inclined lower end of the conveying component 6. The conveying component 6 is installed on the inner wall of the recycling bin 1, and the collection bin 8 is located below the conveying component 6.

[0028] A moving mechanism 4 is installed above the conveying component 6 and on the inner wall of the recycling bin 1. An electromagnet plate 5 is installed at the moving end of the moving mechanism 4, and a cleaning component 12 is provided below the moving path of the electromagnet plate 5.

[0029] Specifically, the guide plate 3 connects to the waste outlet of the CNC machining center, sending the waste material discharged from the CNC machining center that needs to be screened to the recycling box 1 for screening and recycling.

[0030] Collection box 1 (8) is used to collect non-ferrous metal waste, while collection box 2 (11) is used to collect ferrous metal waste.

[0031] The waste material received from the guide plate 3 is sent to the conveying assembly 6 for transportation. During the transportation process, the ferrous metal waste is attracted away by the energized electromagnet plate 5. Due to the transportation effect of the conveying assembly 6, the ferrous metal waste is gradually and evenly attracted to the bottom of the electromagnet plate 5, improving the adsorption efficiency of the electromagnet plate 5 for ferrous metal waste. The non-ferrous metal waste enters the collection box 8 under the transportation of the conveying assembly 6, realizing the screening between ferrous metal waste and non-ferrous metal waste.

[0032] After the ferrous metal waste is attracted by the electromagnet plate 5, the moving end of the moving mechanism 4 drives the electromagnet plate 5 and the ferrous metal waste to move horizontally. When they reach directly above the collection box 11, they stop, at which point the electromagnet plate 5 is de-energized, releasing the ferrous metal waste into the collection box 11, thus completing the recycling of the ferrous metal waste. The moving mechanism 4 is existing technology and will not be described in detail here.

[0033] It should be noted that after the electromagnet plate 5 is de-energized, some magnetism will remain, causing it to attract some iron metal waste. This iron metal waste will be cleaned by the cleaning component 12 during the process of the moving mechanism 4 driving the electromagnet plate 5 back to the top of the conveying component 6, thereby improving the adsorption efficiency of the iron metal waste.

[0034] Furthermore, the conveying assembly 6 includes conveying rollers 61 arranged opposite each other. Both ends of the conveying rollers 61 are rotatably mounted between the front and rear walls of the recycling box 1 via rotating rods 62. One of the rotating rods 62 passes through the side wall of the recycling box 1 and is connected to the output shaft end of the motor 63. A conveyor belt 64 is connected between the conveying rollers 61. A brush 7 is fixedly attached to the bottom of the conveyor belt 64 and to the inner wall of the recycling box 1.

[0035] Specifically, the motor 63 controls the corresponding rotating rod 62 to drive the corresponding conveying roller 61 to rotate, so that the conveyor belt 64 can transport the waste material.

[0036] The brush 7 is designed to clean the conveyor belt 64, sweeping some of the non-ferrous metal waste adhering to the conveyor belt 64 into the collection box 8. In addition, the collection box 8 is equipped with a ramp 9 to prevent non-ferrous metal waste from accumulating at the end of the conveyor belt 64.

[0037] Furthermore, the cleaning component 12 includes a connecting rod 121, which is rotatably mounted on the inner wall of the recycling bin 1. A sleeve 122 is sleeved on the side wall of the connecting rod 121, and a brush 123 is fixedly connected to the side wall of the sleeve 122.

[0038] Furthermore, an actuating rod 124 is vertically fixed to the rear side of the sleeve 122 and to the curved side wall of the connecting rod 121; an adjusting rod 13 is fixed to the rear wall of the electromagnet plate 5 at a position away from the actuating rod 124; an actuating rod 125 is horizontally fixed to the front side of the sleeve 122 and to the curved side wall of the connecting rod 121; and an adjusting rod 14 is fixed to the front wall of the electromagnet plate 5 at a position close to the actuating rod 125.

[0039] Specifically, when the electromagnet plate 5 is directly above the conveyor belt 64, the first trigger rod 124 is set vertically and the second trigger rod 125 is set horizontally. At this time, the second brush 123 is also set horizontally.

[0040] During the process of the moving mechanism 4 driving the electromagnet plate 5 to move towards the second collection box 11, after the electromagnet plate 5 passes over the second brush 123, the adjusting rod 13 pushes the trigger rod 124 to rotate clockwise, which simultaneously drives the connecting rod 121, sleeve 122, second brush 123 and trigger rod 125 to rotate, so that the second brush 123 and trigger rod 125 change from a horizontal state to a vertical state. At this time, the electromagnet plate 5 is suspended directly above the second collection box 11.

[0041] When the electromagnet plate 5 is de-energized and ferrous metal waste is dropped, the moving mechanism 4 drives the electromagnet plate 5 to move towards the collection box 8. During this process, the brush 123 sweeps away the ferrous metal waste that was adsorbed by the electromagnet plate 5, completing the cleaning, until the adjusting rod 14 pushes the trigger rod 125 to rotate counterclockwise, so that the brush 123 returns to the horizontal state.

[0042] Furthermore, button 18 and button 15 are respectively installed on the left and right side walls of the electromagnet plate 5 mounting box. A trigger button 17 is installed on the right inner wall of the recycling box 1 at a position opposite to button 15 via an extension post 16. A trigger button 20 is installed on the left inner wall of the recycling box 1 at a position opposite to button 18 via an extension post 29. A controller 21 is installed on the outer wall of the recycling box 1. The controller 21 is connected to trigger button 17, trigger button 20, the drive end of the moving mechanism 4, and motor 63 via wiring.

[0043] Specifically, button 15 is used to control the de-energization of electromagnet plate 5, button 2 18 is used to control the energization of electromagnet plate 5, trigger button 1 17 is used to control the de-energization of the drive end of moving mechanism 4, and trigger button 2 20 is used to energize motor 63 and de-energize the drive end of moving mechanism 4.

[0044] The specific process is as follows: the moving mechanism 4 controls the electromagnet plate 5 to move to the left. When button 18 touches trigger button 20, both buttons are pressed and triggered. At this time, the drive end of the moving mechanism 4 is de-energized, and the electromagnet plate 5 hovers directly above the conveyor belt 64. Simultaneously, the electromagnet plate 5 is energized to generate magnetism, attracting the ferrous metal waste. The motor 63 is energized to control the conveyor belt 64 to transport the waste. Figure 1 As shown;

[0045] After the timed adsorption of ferrous metal waste is completed, the moving mechanism 4 is automatically energized by the controller 21, causing the electromagnet plate 5 to move to the right. Button 18 and trigger button 20 rebound, the motor 63 is de-energized, and the conveyor belt 64 stops transporting. The electromagnet plate 5 remains energized to adsorb the ferrous metal waste until button 15 touches trigger button 17, at which point both buttons are pressed and triggered. At this time, the drive end of the moving mechanism 4 is de-energized, the electromagnet plate 5 hovers directly above the collection box 11, and the de-energized electromagnet plate 5 throws the adsorbed ferrous metal waste into the collection box 11. Figure 2 As shown.

[0046] After the timer expires, the moving mechanism 4 is automatically powered on by the controller 21 to drive the electromagnet plate 5 to continue moving to the left, repeating the above steps to complete the screening, transportation and recycling of waste materials.

[0047] It should be noted that when recycling bin 1 is not in use, such as Figure 3 As shown, the buttons do not trigger each other.

[0048] It should also be noted that the controller 21 is equipped with a battery, a main control button, and a timer. The battery powers the drive unit of this device, while the main control button is used to control the emergency stop and start-up processes of this device. This is existing technology and will not be described in detail here.

[0049] The working principle and usage process of this utility model: After the utility model is installed, the staff will push the recycling box 1 to the waste outlet of the CNC machining center, wherein the guide docking plate 3 is docked with the waste outlet of the CNC machining center.

[0050] Press the "Start" button on the controller 21, and the moving mechanism 4 controls the electromagnet plate 5 to move to the left. When button 18 touches trigger button 20, both buttons are pressed and triggered. At this time, the drive end of the moving mechanism 4 is de-energized, and the electromagnet plate 5 is suspended directly above the conveyor belt 64. At the same time, the electromagnet plate 5 is energized and generates magnetism. The motor 63 is energized to control the conveyor belt 64 to transport the waste material sent down by the guide docking plate 3. During the transportation process, the magnetic electromagnet plate 5 adsorbs the ferrous metal waste in the waste material. As the conveyor belt 64 transports the waste, the ferrous metal waste will be evenly adsorbed on the bottom of the electromagnet plate 5, realizing the screening of waste material. The non-ferrous metal waste is transported to the collection box 8 by the conveyor belt 64.

[0051] After the timed adsorption of ferrous metal waste is completed, the moving mechanism 4 is automatically powered on by the controller 21, which drives the electromagnet plate 5 to move to the right. Button 18 and trigger button 20 rebound, the motor 63 is de-energized, and the conveyor belt 64 stops transporting. The electromagnet plate 5 remains energized to adsorb the ferrous metal waste until button 15 touches trigger button 17. Both buttons are pressed and triggered. At this time, the drive end of the moving mechanism 4 is de-energized, the electromagnet plate 5 is suspended directly above the collection box 11, and the electromagnet plate 5 is de-energized, throwing the adsorbed ferrous metal waste into the collection box 11.

[0052] During the aforementioned movement, after the electromagnet plate 5 passes over the second brush 123, the adjusting rod 13 pushes the trigger rod 124 to rotate clockwise, simultaneously driving the connecting rod 121, sleeve 122, second brush 123, and trigger rod 125 to rotate, causing the second brush 123 and trigger rod 125 to change from a horizontal state to a vertical state. When the electromagnet plate 5 moves to the left, the second brush 123 can be used to clean the residual iron metal waste at the bottom of the electromagnet plate 5.

[0053] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
