Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment technology for machining, specifically to a chip collection box unit, a chip collection cart with this unit, and an operating method. Background Technology

[0002] When machining parts made of plastic, wood or metal, machine tools will produce some chips. These chips usually fall directly onto the machine tool and need to be cleaned up later. Some of these cleanings are done manually, which is quite troublesome, while others are removed by vacuum cleaners.

[0003] For example, Chinese patent CN208438500U discloses a waste chip collection device after woodworking machinery processing. The existing device uses a waste chip absorber to absorb the waste chips after woodworking machinery processing into a waste chip collection box for easy processing. The activated carbon absorption plate absorbs some small particles of waste chips to avoid environmental pollution. The structure is simple and easy to use.

[0004] However, using the large-diameter vacuum cleaner as shown above is not convenient for vacuuming some narrow spaces on the machine tool. If other sizes of vacuum cleaner head accessories are used, multiple accessories need to be carried, which is inconvenient and easy to miss or lose. At the same time, this device is only suitable for manual hand vacuuming after processing. If waste chips are scattered over a wide area during processing, it will increase the trouble of subsequent cleaning. In addition, the extra time spent cleaning up the site after processing also increases the working hours. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a chip collection box unit, a chip collection cart with this unit, and an operating method, which solves the problems of existing chip collection devices being inconvenient to collect chips in narrow spaces and requiring manual collection after processing, thus increasing working hours.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a chip collection cart, including a trolley and a chip collection box on its top, wherein the chip collection box is provided with a chip collection component that can be removed and cleaned, and the chip collection box is also provided with a wind power component, and the air inlet end of the wind power component is connected to a chip suction structure that can be held by hand or installed on one side of the machining position on the machine tool, and the chip suction structure is installed on the machine tool at an adjustable angle through an adjustable bracket;

[0007] The dust collection structure includes a suction tube, inside which a flat-mouth dust collection component that can extend axially to collect flat dust is slidably disposed, and outside the suction tube is a dust collection structure that can extend axially and unfold to collect waste dust.

[0008] The flat-mouth dust suction assembly includes an elastic thin tube that fits into the inner wall of the air inlet end of the suction tube. Elastic metal strips are attached to both sides of the inner wall of the elastic thin tube. The elastic metal strips bend in their natural state to open the extended end of the elastic thin tube to both sides to form a flat mouth.

[0009] The chip-collecting structure includes a sliding sleeve that is slidably fitted onto the outside of the suction tube, and a plastic sheet is fixedly connected to the inner surface of the sliding sleeve. An elastic strip is pasted on the outer surface of the plastic sheet away from the sliding sleeve to expand that end of the plastic sheet outward. A shrink ring is connected to the outside of the air inlet end of the suction tube, which is fitted onto the outside of the plastic sheet to shrink it into a cylinder. The connection point between the shrink ring and the suction tube corresponds to the top seam of the plastic sheet after it is folded up.

[0010] Preferably, a connecting frame is fixedly connected between the inner ends of the two elastic metal strips, and a push-pull rod is fixedly connected in the middle of the connecting frame. A screw is rotatably connected to the other end of the push-pull rod. A bending part is provided at the hand-held end of the suction tube. The other end of the screw passes through the side wall of the bending part of the suction tube and extends to the outside of the suction tube. The screw is threadedly connected to the suction tube.

[0011] Preferably, the suction tube has several protrusions arranged circumferentially near the handheld end, and the inner side of the sliding sleeve has an annular groove that matches the protrusions. When the sliding sleeve slides to the position where the annular groove fits the protrusions, the shrink ring completely closes the plastic sheet.

[0012] Preferably, the adjustable bracket includes a C-shaped spring clip that can be fitted onto the outside of the dust collection structure, and the inner surface of the C-shaped spring clip is covered with an anti-slip pad. A malleable upright is fixedly connected to the bottom of the C-shaped spring clip, and a base is fixedly connected to the bottom of the malleable upright. A magnet is embedded in the bottom of the base.

[0013] Preferably, the wind power component includes a fan fixedly connected inside the chip collection box. A dust cover is installed inside the chip collection box to cover the fan. The inlet and outlet ends of the fan are respectively connected to an air extraction pipe and an exhaust pipe, and both the air extraction pipe and the exhaust pipe extend to the outside of the chip collection box. One end of the air extraction pipe is connected to the handheld end of the suction tube, and the upper end of the exhaust pipe is connected to the upper rear corner of the left side of the chip collection box.

[0014] Preferably, the top cover of the chip collection box is provided with a chip separation component, which includes a top cover and a cylinder connected to its bottom. An insertion hole for inserting an adjustable bracket is provided at one corner inside the top cover and on the outside of the cylinder. An air inlet connected to an exhaust pipe is provided on one side of the cylinder, and a sealing ring that fits against the inner wall of the chip collection box is provided on the end face of the air inlet. A recessed cylinder is provided at the bottom of the cylinder. Fan-shaped holes are provided at both the upper and lower ends of the cylinder, and the upper and lower fan-shaped holes are staggered. The chip debris is discharged into the chip collection component below through the fan-shaped holes. A rotating shaft is rotatably connected to the center of the cylinder. A baffle that can cover the fan-shaped holes is fixedly connected to the surface of the rotating shaft and above the fan-shaped holes, and the upper and lower baffles are in corresponding positions.

[0015] Preferably, the surface of the rotating shaft and the inside of the cylinder are circumferentially fixedly connected to multiple sets of rotating frames, and the inside of the rotating frames is provided with a moving screen. The top of the top cover is fitted with a filter window through an opening groove.

[0016] The filter window includes a snap-fit ​​frame and a connecting block located below its center. Multiple sets of elastic strips are fixedly connected between the side of the connecting block and the bottom of the snap-fit ​​frame to elastically press the connecting block down. A static screen is fixedly connected between the snap-fit ​​frame and the connecting block and pasted on the top of the elastic strips. A rotating block is fixedly connected to the top of the rotating shaft. The top of the rotating block and the bottom of the connecting block are elastically pressed together and both are provided with protrusions. When the rotating block rotates, the contact of the protrusions causes the connecting block to drive the static screen to vibrate up and down.

[0017] The present invention also discloses a chip collection box unit, including a chip collection assembly. The chip collection assembly includes a shape memory metal frame and a collection bag installed inside it for receiving waste chips. Support rods are installed at the four corners of the shape memory metal frame via corner brackets. A heating support frame for supporting the shape memory metal frame is installed in the middle layer of the inner surface of the chip collection box. The shape memory metal frame is heated and restored by being clamped in the heating support frame. Positioning holes for inserting support rods are opened at the four corners of the heating support frame.

[0018] This invention also discloses an operating method for a chip collection cart, specifically including the following steps:

[0019] S1. Activate the wind power component, hold the dust suction device to the dust and extract the dust, and finally discharge the dust into the dust collection component for collection.

[0020] S2. When vacuuming up debris in narrow gaps, push out the flat-mouthed debris suction component to make the suction end of the air suction tube form a flat mouth for suctioning debris.

[0021] S3. When installing the chip suction structure next to the machining position, clip the chip suction structure onto the adjustable bracket, then attach the adjustable bracket to the machine tool, and adjust the angle of the adjustable bracket to align the chip suction structure with the machining position.

[0022] S4. When adjusting the angle of the chip suction structure in S3, the air inlet end of the chip suction structure can be adjusted to be below the processing position, and the chip receiving structure can be pushed out to unfold the plastic sheet to receive the waste chips.

[0023] Preferably, when the chip-collecting structure is deployed in step S4, the flat-mouth chip-collecting component must be retracted to prevent waste chips from getting stuck between the flat-mouth chip-collecting component and the chip-collecting structure.

[0024] Beneficial effects

[0025] This invention provides a chip collection box unit, a chip collection cart with this unit, and a method for operating it. Compared with the prior art, it has the following advantages:

[0026] 1. This chip collection box unit, the chip collection cart with this unit, and the operation method are described. The chip suction structure can be used by hand or mounted on a machine tool with an adjustable bracket. Inside the chip suction structure, a flat-mouth chip suction component is set. When pushed out, it can automatically unfold to both sides to form a flat mouth, which is convenient for suctioning dust in narrow spaces and provides stronger airflow. It can also automatically return to its original shape after being retracted. On the outside, a chip receiving structure is set. When pushed out, it can automatically unfold to expand the range and easily catch falling chips, improving chip suction efficiency. It can also automatically close and return to its original shape after being retracted. There is no need to carry other accessories, making it convenient to use.

[0027] 2. The chip collection box unit, the chip collection cart with this unit, and the operation method, by setting an adjustable bracket, allow the chip collection structure to be directly installed on one side or below the processing position using magnetic attraction, which can pick up chips faster and reduce the chance of large-scale chip spillage. At the same time, the adjustable bracket is malleable, which facilitates the adjustment of the position of the chip collection structure. It can also be directly pulled off and separated without using the adjustable bracket, making it convenient to use.

[0028] 3. The chip collection box unit, the chip collection cart with this unit, and the operation method are as follows: By setting a waste chip separation component above the chip collection assembly, the wind-powered component draws waste chips into the waste chip separation component for filtration and separation, and the waste chips fall into the chip collection assembly for collection. The bottom outlet of the waste chip separation component adopts staggered fan-shaped holes with rotating baffles to achieve staggered opening of the upper and lower fan-shaped holes, thereby allowing a certain amount of debris to accumulate in the sinking cylinder before being discharged, minimizing the amount of wind blowing downwards and reducing the problem of waste chips being blown up from below.

[0029] 4. The chip collection box unit, the chip collection cart with this unit, and the operating method utilize an impeller-type structure set inside the cylinder. The rotating frame and the moving screen form the blades of the impeller-type structure, which can be driven by the exhaust air to rotate. At the same time, it can also achieve preliminary filtration, filtering out some debris first. The stationary screen then performs secondary filtration. The rotational force can also promote the rotation of the baffle to achieve intermittent chip removal. Simultaneously, when the rotating shaft rotates, it can also drive the rotating block to rotate. During the process of mutual contact with the protrusion at the bottom of the connecting block, the stationary screen vibrates, which can promote the shedding of the debris blocking it, achieving an automatic unblocking effect. It can maintain the filtration effect for a long time, and no additional drive source is required, thus reducing costs.

[0030] 5. The chip collection box unit, the chip collection cart with this unit, and the operation method: The chip collection component can be removed separately and mounted under the machining position on the machine tool to directly collect chips. The chip collection component uses a malleable shape memory metal frame as the main frame to open the collection bag. The opening of the chip collection component bag can be adjusted to the required shape to adapt to the obstruction of accessories such as tool holders on the machine tool, so as to minimize leakage. After being installed back into the chip collection box, it can automatically return to its original shape by heating the heating support frame without affecting the installation and making it convenient to use.

Detailed Implementation

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] This invention discloses a chip collection vehicle and provides four technical solutions:

[0047] Figures 1-3 The first embodiment is shown: it includes a trolley 1 and a chip collection box 2 on its top. The chip collection box 2 is equipped with a chip collection component 3 that can be removed and cleaned. The chip collection box 2 is also equipped with a wind power component 4. The air inlet of the wind power component 4 is connected to a chip suction structure 5 that can be held by hand or installed on one side of the machining position on the machine tool. The chip suction structure 5 is installed on the machine tool at an adjustable angle via an adjustable bracket 6.

[0048] The dust collection structure 5 includes a suction tube 51, a flat-mouth dust collection component 52 that can extend axially to collect flat dust is slidably disposed inside the suction tube 51, and a dust collection structure 53 that can extend axially and unfold to collect waste dust is sleeved on the outside of the suction tube 51.

[0049] The flat-mouth dust collection assembly 52 includes an elastic thin cylinder 521 that fits into the inner wall of the air inlet end of the suction cylinder 51. Elastic metal strips 522 are attached to opposite sides of the inner wall of the elastic thin cylinder 521. The elastic metal strips 522 bend in their natural state to open the extended ends of the elastic thin cylinder 521 to both sides to form a flat mouth. A connecting frame 523 is fixedly connected between the inner ends of the two elastic metal strips 522. A push-pull rod 524 is fixedly connected in the middle of the connecting frame 523. A screw 525 is rotatably connected to the other end of the push-pull rod 524. A bending part is provided at the hand-held end of the suction cylinder 51. The other end of the screw 525 passes through the side wall of the bending part of the suction cylinder 51 and extends to the outside of the suction cylinder 51. The screw 525 is threadedly connected to the suction cylinder 51.

[0050] When suctioning debris in narrow spaces, the screw 525 is rotated to push the elastic thin cylinder 521 out through the push-pull rod 524. The outer end of the elastic metal strip 522 loses the constraint of the inner wall of the suction tube 51 and springs outward, thereby spreading the elastic thin cylinder 521 to both sides to form a flat opening. After the screw 525 retracts the elastic thin cylinder 521, the suction tube 51 squeezes and constrains the elastic metal strip 522 again. With the elasticity of the elastic thin cylinder 521, the elastic thin cylinder 521 is re-formed into a cylinder and fits against the inner wall of the suction tube 51.

[0051] The chip-collecting structure 53 includes a sliding sleeve 531 that is slidably fitted onto the outside of the suction tube 51. A plastic sheet 532 is fixedly connected to the inner surface of the sliding sleeve 531. An elastic strip 534 is attached to the outer surface of the plastic sheet 532 away from the sliding sleeve 531 to expand that end of the plastic sheet 532 outward. A shrink ring 54 is connected to the outside of the air inlet end of the suction tube 51 and is fitted onto the outside of the plastic sheet 532 to shrink it into a cylinder. The connection point between the shrink ring 54 and the suction tube 51 corresponds to the top seam of the plastic sheet 532 after it is folded up. Several protrusions 55 are arranged circumferentially on the outside of the suction tube 51 near the hand-held end. An annular groove 533 that matches the protrusions 55 is opened on the inner side of the sliding sleeve 531. When the sliding sleeve 531 slides to the position where the annular groove 533 fits the protrusions 55, the shrink ring 54 completely shrinks the plastic sheet 532. The sliding sleeve 531 can be stuck by the protrusions 55 to prevent the plastic sheet 532 from easily extending.

[0052] When using the chip-receiving structure 53, pushing the sliding sleeve 531 causes the plastic sheet 532 to extend. The part of the plastic sheet 532 that is no longer constrained by the shrink ring 54 unfolds under the action of the elastic strip 534. After pushing the sliding sleeve 531 back, the plastic sheet 532 is once again constrained by the shrink ring 54 and retracts.

[0053] The chip suction structure 5 can be used handheld for chip suction or mounted on a machine tool with an adjustable bracket 6. Inside the chip suction structure 5 is a flat chip suction component 52, which automatically unfolds to both sides to form a flat opening when extended, making it convenient for suctioning dust in narrow spaces and providing stronger airflow. It can also automatically return to its original shape when retracted. On the outside is a chip receiving structure 53, which automatically unfolds to expand the range when extended, making it convenient to catch falling chips and improving chip suction efficiency. It can also automatically retract and return to its original shape when retracted, eliminating the need to carry other accessories and making it convenient to use.

[0054] Figures 7-8 The second embodiment is shown. The main difference from the first embodiment is that the adjustable bracket 6 includes a C-shaped spring buckle 61 that can be sleeved on the outside of the dust collection structure 5. The inner surface of the C-shaped spring buckle 61 is covered with an anti-slip pad 62. A malleable upright rod 63 is fixedly connected to the bottom of the C-shaped spring buckle 61. A base 64 is fixedly connected to the bottom end of the malleable upright rod 63. A magnet 65 is embedded in the bottom of the base 64. A pull ring is provided on one side of the top of the base 64 to facilitate lifting the base 64. The pull ring is eccentrically positioned to facilitate lifting the base 64 from one side by overcoming the magnetic force.

[0055] By setting the adjustable bracket 6, the chip suction structure 5 can be directly installed on one side or below the processing position using magnetic attraction, which can pick up chips faster and reduce the chance of large-scale chip spillage. At the same time, the adjustable bracket 6 is malleable, making it convenient to adjust the position of the chip suction structure 5. It can also be directly pulled off and separated without using the adjustable bracket 6, making it convenient to use.

[0056] When using the adjustable bracket 6, open the C-type spring clip 61 and put it on the outside of the chip suction structure 5. Then, attach the adjustable bracket 6 to the appropriate position on the machine tool using the magnet 65. Finally, move the malleable upright rod 63 to adjust the chip suction structure 5 to the appropriate angle.

[0057] Figures 9-11 The third embodiment is shown. The main difference from the second embodiment is that the wind power component 4 includes a fan 41 fixedly connected inside the chip collection box 2. A dust cover 7 covering the fan 41 is installed inside the chip collection box 2. The inlet and outlet ends of the fan 41 are respectively connected to an air extraction pipe 42 and an exhaust pipe 43, and both the air extraction pipe 42 and the exhaust pipe 43 extend to the outside of the chip collection box 2. One end of the air extraction pipe 42 is connected to the handheld end of the suction tube 51, and the upper end of the exhaust pipe 43 is connected to the upper rear corner of the left side of the chip collection box 2.

[0058] The top cover of the chip collection box 2 is equipped with a chip separation assembly 8, which includes a top cover 81 and a cylinder 82 connected to its bottom. The bottom of the cylinder 82 is bucket-shaped to facilitate the movement of chips towards the center. The upper surface of the cylinder 82 is open and is fixed to the top cover 81 by bolts on the side, allowing for disassembly for inspection or cleaning. An insertion hole 83 for inserting an adjustable bracket 6 is provided in one corner inside the top cover 81 and on the outside of the cylinder 82. An air inlet connected to the exhaust pipe 43 is provided on one side of the cylinder 82. Furthermore, the air inlet end face is provided with a sealing ring 84 that fits against the inner wall of the chip collection box 2. The bottom of the cylinder 82 is provided with a recessed cylinder 85. Both the upper and lower ends of the cylinder 82 are provided with fan-shaped holes 86, and the upper and lower fan-shaped holes 86 are staggered. Waste chips are discharged into the lower chip collection assembly 3 through the fan-shaped holes 86. The center of the cylinder 82 is rotatably connected to a rotating shaft 87. The surface of the rotating shaft 87 and the upper part of the fan-shaped holes 86 are fixedly connected to a baffle 88 that can cover the fan-shaped holes 86, and the upper and lower baffles 88 are in corresponding positions.

[0059] By setting a waste chip separation component 8 above the chip collection component 3, the wind-powered component 4 can draw waste chips into the waste chip separation component 8 for filtration and separation, and then collect the waste chips in the chip collection component 3. The bottom outlet of the waste chip separation component 8 uses staggered fan-shaped holes 86 in conjunction with a rotating baffle 88 to achieve staggered opening of the upper and lower fan-shaped holes 86, so that a certain amount of debris can accumulate in the sinking cylinder 85 before being discharged, minimizing the amount of wind blowing downwards and reducing the problem of waste chips being blown up from below.

[0060] The blower 41 sucks up debris through the exhaust pipe 42 and the debris suction structure 5, and then discharges it into the cylinder 82 through the exhaust pipe 43, which drives the moving screen 810 and the rotating shaft 87 to rotate, thereby driving the upper and lower baffles 88 to rotate. When the upper baffle 88 opens the upper fan-shaped hole 86, the lower baffle 88 closes the lower fan-shaped hole 86. Only a small stream of air flows downward between the fan-shaped holes 86, which causes the debris to gradually fall into the cylinder 82 and then be discharged downward into the debris collection assembly 3.

[0061] Figures 10-12 The fourth embodiment is shown. The main difference from the third embodiment is that: multiple sets of rotating frames 811 are circumferentially fixedly connected to the surface of the rotating shaft 87 and inside the cylinder 82, and a moving screen 810 is provided inside the rotating frame 811. The moving screen 810 is finer and can be driven to rotate by the exhaust air. The top of the top cover 81 is fitted with a filter window 89 through an opening slot.

[0062] The filter window 89 includes a snap-fit ​​frame 891 and a connecting block 892 located below its center. Multiple sets of elastic strips 893 are fixedly connected between the side of the connecting block 892 and the bottom of the snap-fit ​​frame 891, which elastically press the connecting block 892 down. A static screen 894 is fixedly connected between the snap-fit ​​frame 891 and the connecting block 892 and is pasted on the top of the elastic strips 893. A rotating block 812 is fixedly connected to the top of the rotating shaft 87. The top of the rotating block 812 and the bottom of the connecting block 892 are elastically pressed together and both are provided with protrusions 813. When the rotating block 812 rotates, the contact of the protrusions 813 causes the connecting block 892 to drive the static screen 894 to vibrate up and down.

[0063] By setting an impeller-type structure inside the cylinder 82, the rotating frame 811 and the moving screen 810 form the blades of the impeller-type structure, which can be driven to rotate by the exhaust air. At the same time, it can also achieve preliminary filtration, filtering out some debris first. The stationary screen 894 then performs secondary filtration. The rotational force can also promote the rotation of the baffle 88 to achieve intermittent debris discharge. Meanwhile, when the rotating shaft 87 rotates, it can also drive the rotating block 812 to rotate. During the process of mutual contact with the protrusion 813 at the bottom of the connecting block 892, the stationary screen 894 vibrates, which can promote the falling off of the debris blocking it, achieving an automatic unblocking effect. The filtration effect can be maintained for a long time, and no additional drive source is required, reducing costs.

[0064] The exhaust air carries debris and blows it toward the moving screen 810, where it is filtered once. Then the air rises and passes through the stationary screen 894 for a second filtration before being discharged. At the same time, the air drives the moving screen 810 and the rotating shaft 87 to rotate, which in turn drives the rotating block 812 to rotate. The protrusion 813 on the rotating block 812 collides with the protrusion 813 at the bottom of the connecting block 892, causing the stationary screen 894 to vibrate up and down, shaking off the debris attached to it.

[0065] See Figure 13 The present invention also discloses a chip collection box unit, including a chip collection assembly 3. The chip collection assembly 3 includes a shape memory metal frame 31 and a collection bag 32 installed on its inner side for receiving waste chips. Support rods 34 are installed at the four corners of the shape memory metal frame 31 through corner brackets 33. A heating support frame 35 supporting the shape memory metal frame 31 is installed in the middle layer of the inner surface of the chip collection box 2. The shape memory metal frame 31 is heated and restored by being clamped in the heating support frame 35. Positioning holes 36 for the support rods 34 to be inserted are opened at the four corners of the heating support frame 35. The chip collection box 2 is also equipped with a battery and control components for controlling the fan 41 and controlling the heating support frame 35 to be energized and heated. The inner wall of the chip collection box 2 is insulated at the installation position of the heating support frame 35. A control panel is installed on the side wall of the chip collection box 2 for control.

[0066] The chip collection assembly 3 can be removed separately and mounted under the machining position on the machine tool to directly collect chips. The chip collection assembly 3 uses a malleable shape memory metal frame 31 as the main frame to support the collection bag 32. The opening of the chip collection assembly 3 bag can be adjusted to the required shape to accommodate the obstruction of accessories such as tool holders on the machine tool, which can minimize leakage. After being installed back into the chip collection box 2, it can automatically return to its original shape by heating the heating support frame 35 without affecting the installation and making it convenient to use.

[0067] When taking out the chip collection assembly 3 for use, first open the chip separation assembly 8, and then directly lift the memory metal frame 31 together with the collection bag 32, corner bracket 33, and support rod 34. It can be placed on the machine tool and supported by the support rod 34 to receive the chips. If there are parts on the machine tool that obstruct the normal placement of the chip collection assembly 3, bend the memory metal frame 31 to a suitable angle to fit the parts. When putting it back into the chip collection box 2, first empty the chips, and then place the memory metal frame 31 face down on the heating support frame 35. Start the heating mode to heat the memory metal frame 31 with the heating support frame 35, so that it automatically recovers.
