Description

Technical Field

[0001] This application relates to the field of cutting and processing technology, and in particular to a cutting device with a waste chip collection function. Background Technology

[0002] Existing cutting equipment requires continuous spraying of working fluid onto the part of the workpiece being cut during the cutting process, so that the working fluid can carry away the metal scraps at the cut point.

[0003] Chinese patent CN214518031U discloses an electrical discharge machining (EDM) device, including a base with an upper support plate on it; a collection groove is formed on the top of the upper support plate, and a drain pipe is connected to the collection groove; the drain pipe is connected to a filter box, and a drain port is formed on the filter box; a filter chamber and a collection chamber are provided inside the filter box, and a partition is provided between the filter chamber and the collection chamber; a through hole for connecting the filter chamber and the collection chamber is formed on the side of the partition away from the drain port; a hopper for covering the through hole is connected to the partition; the hopper has water permeable holes and a filter layer is provided on the hopper; a drainage structure is provided inside the filter chamber; a magnet for attracting metal scrap is slidably connected inside the filter chamber, and the top of the magnet is slidably connected to the bottom part of the hopper, and the magnet moves laterally between the drain port and the hopper; a ball screw for driving the movement of the magnet is provided inside the filter chamber.

[0004] The device uses a motor to drive a ball screw to rotate, which in turn drives a magnet to repeatedly approach the hopper. This allows the metal scraps above the baffle to be drawn into the hopper, facilitating the collection and processing of the metal scraps in the working fluid. However, when the magnet moves away from the hopper, some of the metal scraps in the hopper are drawn back to the baffle, resulting in poor collection of the metal scraps.

[0005] Therefore, there is a need to provide a cutting device with a waste collection function. Utility Model Content

[0006] To address the problem of poor metal scrap collection in existing cutting equipment, this application provides a cutting device with scrap collection function.

[0007] This application provides a cutting device with waste collection function, which adopts the following technical solution: it includes a cutting component and a filtering component. The cutting component includes a cutting table and a cutting device and a liquid spraying device disposed on the cutting table. The cutting device can cut the workpiece. A liquid holding tank is provided on the cutting table. The liquid holding tank can receive the working liquid sprayed by the liquid spraying device. A sewage outlet is provided on the tank wall of the liquid holding tank.

[0008] The filter assembly includes a mounting housing, a separator, a magnetic component, and a drive unit. The separator is located inside the mounting housing and divides the interior of the housing into a liquid-containing chamber and a liquid-free chamber. The liquid-containing chamber has an inlet and a drain outlet on its wall. The inlet is connected to the drain outlet via a pipe. A filter screen is installed in the drain outlet. The magnetic component is located in the liquid-free chamber. A collection trough is formed on the side of the separator away from the magnetic component. The drive unit is connected to the magnetic component and can drive the magnetic component to rotate, so that the magnetic component rotates towards the collection trough when it is close to the separator and away from the collection trough when it is away from the separator.

[0009] By adopting the above technical solution, the working fluid sprayed by the spraying device carries the metal scraps cut by the cutting device into the liquid collection tank, then through the drain outlet and along the pipe into the liquid chamber, and then through the filter screen and out of the liquid chamber from the drain outlet. The metal scraps entering the liquid chamber will remain on the separator under their own weight. The user can drive the magnetic component to rotate in the liquid-free chamber through the drive unit, so that the distance between the magnetic component and the separator is closer when rotating towards the collection tank and farther when rotating away from the collection tank. This makes the force exerted by the magnetic component on the metal scraps on the separator greater in the direction of approaching the collection tank and less in the direction of away from the collection tank. This allows the magnetic component to continuously pull the metal scraps on the separator into the collection tank without pulling them out of the collection tank, thus making the metal scrap collection effect of the cutting device with scrap collection function better.

[0010] Specifically, the drive unit includes a conveyor belt and a drive motor. One end of the conveyor belt is located below the collection trough, and the other end of the conveyor belt extends away from the collection trough. The magnetic element is located on the belt body of the conveyor belt.

[0011] The drive motor is connected to the conveyor belt and can drive the conveyor belt to rotate.

[0012] By adopting the above technical solution, the drive motor can drive the magnetic component to rotate by driving the conveyor belt to rotate.

[0013] Furthermore, the separator includes a fixing plate and a separating plate. A separating port is provided on one side of the mounting housing. One side of the separating plate can pass through the separating port and be inserted into the interior of the mounting housing and abut against the fixing plate to form the separator. The material collection trough is provided on the separating plate.

[0014] By adopting the above technical solution, users can recycle the metal scraps collected on the separation plate by pulling it out of the installation housing from the separation port.

[0015] Furthermore, a slot is provided on the inner wall of the mounting housing along the direction from near to away from the separation port. One end of the slot extends to the separation port and forms an opening. The edge of the separation plate is provided with a plug-in protrusion, which can be inserted into the slot and slide along the slot.

[0016] By adopting the above technical solution, the insertion protrusion can cooperate with the slot so that the separation plate can slide along the slot.

[0017] Furthermore, a handle is provided on the side of the separating plate away from the fixing plate.

[0018] By adopting the above technical solution, users can move the separation plate by holding the handle.

[0019] Furthermore, the surface of the fixing plate is inclined upward in the direction from approaching to moving away from the separating plate.

[0020] By adopting the above technical solution, the inclined fixed plate surface not only allows the metal scrap falling on the fixed plate to easily slide along the fixed plate into the collection trough, but also makes it difficult for the metal scrap to slide away from the collection trough along the fixed plate, thereby further improving the collection effect of a cutting device with scrap collection function on metal scrap in the working fluid.

[0021] Furthermore, the drive unit also includes a sleeve, a plug, and an elastic element. The sleeve is disposed on the belt body of the conveyor belt, and a limiting protrusion is provided at the opening of the sleeve.

[0022] One end of the insert is connected to the magnetic component, and the other end of the insert is inserted into the sleeve and has an abutment protrusion. The abutment protrusion can abut against the side of the limiting protrusion near the conveyor belt.

[0023] The elastic element is disposed between the insert and the inner wall of the sleeve and is capable of applying a force to the insert away from the conveyor belt.

[0024] By adopting the above technical solution, the elastic element applies a force away from the conveyor belt to the insert, so that the magnetic element can always abut against the fixed plate when the conveyor belt carries the sleeve close to the collection trough; and the abutment protrusion can abut against the side of the limiting protrusion near the conveyor belt, so as to restrict the elastic element from completely pushing the insert out of the sleeve.

[0025] Furthermore, the filter is located directly above the conveyor belt.

[0026] By adopting the above technical solution, the magnetic component can suck down the metal debris on the filter screen when it passes directly below the filter screen, so as to clean the filter screen.

[0027] In summary, this application includes the following beneficial technical effects:

[0028] The system includes a cutting assembly and a filtering assembly. The cutting assembly includes a cutting table and a cutting device and a spraying device mounted on the cutting table. The cutting device can cut the workpiece. A liquid-collecting tank is provided on the cutting table to collect the working fluid sprayed by the spraying device. A drain outlet is provided on the tank wall. The filtering assembly includes a mounting housing, a separator, a magnetic component, and a drive unit. The separator is located inside the mounting housing and divides the interior of the housing into a liquid-containing chamber and a liquid-free chamber. An inlet and a drain outlet are provided on the wall of the liquid-containing chamber. The inlet is connected to the drain outlet via a pipe. A filter screen is provided in the drain outlet. The magnetic component is located in the liquid-free chamber. A collection trough is provided on the side of the separator away from the magnetic component. The drive unit is connected to the magnetic component and can drive the magnetic component to rotate. The magnetic component rotates towards the collection trough when it is close to the separator and away from the collection trough when it is away from the separator, thereby ensuring that the working fluid sprayed by the spraying device is... Metal scraps cut by the cutting device first enter the liquid collection tank, then pass through the drain outlet and along the pipe into the liquid chamber. After passing through a filter screen, they exit the liquid chamber from the drain outlet. The metal scraps in the liquid chamber remain on the separator due to their own weight. The user can drive a magnetic component to rotate in the liquid-free chamber via a drive unit. This ensures that the magnetic component is closer to the separator when rotating towards the collection tank and farther away when rotating away from the collection tank. This results in a greater force exerted by the magnetic component on the metal scraps on the separator towards the collection tank and a smaller force towards the separation tank. This allows the magnetic component to continuously pull the metal scraps from the separator into the collection tank without pulling them out, thus achieving better collection of metal scraps from the working fluid in a cutting device with scrap collection function.

[0033] The following is in conjunction with the appendix Figure 1-3 Further explanation:

[0034] See Figure 1 and Figure 2 The cutting device with waste collection function provided in this application includes: a cutting component 1 and a filtering component 2. The cutting component 1 includes a cutting table 11 and a cutting device 12 and a liquid spraying device (not shown in the figure) disposed on the cutting table 11. The cutting device 12 can be a cutting device that uses a knife or electric spark to cut, so that the workpiece can be cut by the cutting device 12. A liquid holding tank 111 is provided on the cutting table 11. The liquid holding tank 111 can receive the working liquid sprayed by the liquid spraying device. A sewage outlet is provided on the tank wall of the liquid holding tank 111.

[0035] See Figure 2 and Figure 3 The filter assembly 2 includes a mounting housing 21, a separator 22, two magnetic components 23, and a drive unit 24. The separator 22 is located inside the mounting housing 21 and divides the interior of the mounting housing 21 into a liquid chamber 211 and a non-liquid chamber 212. The liquid chamber 211 has an inlet and a drain on its wall. The inlet is connected to the drain via a pipe 13. The drain contains a filter screen 213. The separator 22 includes a fixing plate 221 and a separating plate 222. One side of the fixing plate 221 is connected to the side of the inner wall of the mounting housing 21 away from the drain. The inner wall of the mounting housing 21 also has a separating port located below the drain. The surface of the fixing plate 221 is inclined upward in the direction from the direction of approaching to the direction of away from the separating port, so that metal scraps falling on the fixing plate 221 can easily slide along the fixing plate 221 to the separating port.

[0036] See Figure 2 and Figure 3The inner wall of the mounting housing 21 has slots facing each other along the direction from the direction of approach to the separation port. One end of each slot extends to the separation port and forms an opening. The two sides of the separation plate 222 are provided with insertion protrusions 2221. The two insertion protrusions 2221 correspond one-to-one with the two slots, so that each insertion protrusion 2221 can be inserted into the corresponding slot and slide along the slot. One side of the separation plate 222 can pass through the separation port and be inserted into the interior of the mounting housing 21 and abut against the fixing plate 221 to form a separator 22. The material collection trough is opened on the top plate surface of the separation plate 222. The side of the separation plate 222 away from the fixing plate 221 is provided with a handle 2222, so that the user can move the separation plate 222 by holding the handle 2222.

[0037] See Figure 2 and Figure 3 The drive unit 24 includes a conveyor belt 241, a drive motor 242, two sleeves 25, two inserts 26, and two elastic elements 27. The conveyor belt 241 is located in the liquid-free chamber 212. One end of the conveyor belt 241 is located below the collection trough and the filter screen 213, and the other end of the conveyor belt 241 extends away from the collection trough. The drive motor 242 is connected to the conveyor belt 241 and can drive the conveyor belt 241 to rotate. The two sleeves 25 are equally spaced on the belt body of the conveyor belt 241. Each sleeve 25 has a limiting protrusion at its opening. The two sleeves 25, two inserts 26, two elastic elements 27, and two magnetic elements 23 correspond one-to-one. The magnetic elements 23 can be rollers made of magnetic material. Each magnetic element 23 is rotatably connected to the opposite side. One end of each insertion post 26 is inserted into a corresponding sleeve 25 and has an abutment protrusion. Each abutment protrusion abuts against the side of a corresponding limiting protrusion near the conveyor belt 241. Each elastic element 27 is disposed between the inner wall of the corresponding insertion post 26 and the corresponding sleeve 25. Each elastic element 27 can be a compression spring, so that a force away from the conveyor belt 241 can be applied to the insertion post 26 through the elastic element 27, so that the magnetic element 23 above the conveyor belt 241 can always abut against the bottom of the fixing plate 221 and the separating plate 222. The abutment protrusion abuts against the side of the limiting protrusion near the conveyor belt 241, so as to limit the elastic element 27 from completely pushing the insertion post 26 out of the sleeve 25.

[0038] The working principle of the cutting device with waste collection function of this application is as follows:

[0039] The working fluid sprayed by the spraying device carries the metal scraps cut by the cutting device 12 into the liquid collection tank 111, then through the drain outlet and along the pipe 13 into the liquid chamber 211. It then passes through the filter screen 213 and exits the liquid chamber 211 from the drain outlet. The metal scraps inside the liquid chamber 211 remain on the separator 22 due to their own weight. The user can drive the conveyor belt 241 to rotate via the drive motor 242, causing the two magnetic components 23 to rotate. This causes the magnetic component 23 closer to the separator 22 to rotate towards the collection trough and away from the separator 22. The magnetic component 23 rotates away from the collection trough, so that the distance between the magnetic component 23 and the separator 22 is closer when rotating towards the collection trough and farther when rotating away from the collection trough. This results in a larger force exerted by the magnetic component 23 on the metal scraps on the separator 22 in the direction of approaching the collection trough and a smaller force in the direction of away from the collection trough. This allows the magnetic component 23 to continuously pull the metal scraps on the separator 22 into the collection trough without pulling the metal scraps out of the collection trough.

[0040] The inclined fixed plate 221 allows metal scraps falling on it to easily slide down the fixed plate 221 into the collection trough, while also preventing them from sliding off the fixed plate 221. After a certain amount of metal scraps are collected in the collection trough, the user can pull the separating plate 222 out of the separating port into the mounting housing 21 to recycle the metal scraps collected on the separating plate 222. This makes the cutting equipment with scrap collection function have a better collection effect on metal scraps in the working fluid.

[0041] It should be noted that the above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
