Description

Technical Field

[0001] The utility model belongs to the technical field of sawing machines, in particular to a chip liquid separator for a band sawing machine. Background Art

[0002] Band saws are machine tools used for sawing various metal materials. They are divided into horizontal and vertical types according to their structure, and semi-automatic, fully automatic, and CNC according to their functions. Horizontal band saws can be further divided into double-column and scissor-type.

[0003] During sawing operations, it is often necessary to spray cutting fluid onto the saw strips for lubrication, cooling, degreasing, cleaning, corrosion prevention, and rust prevention. After passing through the sawing station, the cutting fluid falls together with the cut iron chips.

[0004] However, most of the band saw machines in the existing technology lack an effective chip-liquid separation structure, and cannot efficiently achieve solid-liquid separation and classified output of chip liquid and iron chips, which is not conducive to the recycling of chip liquid and the collection of iron chips, and there is room for cost reduction. Utility Model Content

[0005] The purpose of the utility model is to solve the above problems in the prior art and to propose a chip liquid separator for a band sawing machine.

[0006] In order to achieve the purpose of innovation of this utility model, the following technical solutions can be used:

[0007] A chip liquid separator for a band sawing machine is arranged on the base of the sawing machine and located below the sawing station, comprising:

[0008] A filtering structure, the filtering surface of which is located below the sawing station;

[0009] A magnetic attraction structure, wherein the magnetic attraction surface of the magnetic attraction structure is close to the filtering surface and is used to absorb iron filings;

[0010] a scraping structure, wherein a scraping end of the scraping structure is in contact with the magnetic surface and is used to scrape off iron chips;

[0011] The material receiving structure includes a liquid receiving box arranged below the filter surface.

[0012] The chip liquid separator of the present invention is mainly used to separate the chip liquid and iron chips and output them in a classified manner to realize the recycling of the chip liquid and the collection of iron chips. The filtering structure is connected to the bottom of the sawing station. The chip liquid and the fallen iron chips in the sawing process are separated into solid and liquid after passing through the filtering surface. The filtered chip liquid flows into the liquid receiving box of the receiving structure below, and the iron chips remain on the filtering surface. The magnetic structure has a magnetic surface with magnetism, which is close to the filtering surface for absorbing the iron chips thereon. The scraping structure is used to scrape off the iron chips on the magnetic surface. The scraped iron chips can be collected by the corresponding iron chip receiving assembly, or even spilled on the ground for subsequent cleaning and collection.

[0013] In the above-mentioned chip liquid separator of the band saw machine, the filtering structure includes at least two guide rollers rotatably connected to the base, a filter conveyor belt is wound between the guide rollers, and at least one guide roller is transmission-connected to the output end of the filter drive motor.

[0014] The filtering structure is essentially a conveyor belt. The filter conveyor belt of the conveyor belt has a mesh and has a filtering function. The filter conveyor belt is wrapped around the guide roller. The filter drive motor drives the guide roller to rotate, and then drives the filter conveyor belt to rotate. While filtering, the filtered iron filings are transmitted to the rear to facilitate the magnetic suction structure at the rear to absorb the iron filings.

[0015] In the above-mentioned chip liquid separator of the band saw machine, the filter conveyor belt is arranged horizontally, the filter surface is formed on the upper side thereof, and the magnetic attraction structure is close to the downstream of the filter surface.

[0016] The filter conveyor belt is arranged horizontally to ensure that the chip liquid can flow directly below, avoiding the problem of being directed to the low side and difficult to receive. It is also beneficial for the filtered iron chips to remain on the filter conveyor belt and be transported backward stably.

[0017] In the above-mentioned chip liquid separator of the band saw machine, the magnetic structure includes a magnetic roller rotatably connected to the base, a magnetic force generating component is provided in the magnetic roller, the magnetic surface is formed on the outer wall of the magnetic roller, and the magnetic roller is transmission-connected to the output end of the magnetic drive motor.

[0018] The outer wall of the magnetic roller forms a magnetic surface, and the internal magnetic force generating component is used to generate magnetic force, so that iron filings of various sizes can be attracted to the magnetic surface. The magnetic drive motor drives the magnetic roller to rotate, so that the magnetic surface with iron filings and the scraping structure cooperate to scrape off the iron filings. After scraping off the iron filings, the magnetic surface rotates to a position that cooperates with the filter structure to continue to attract iron filings. This cycle completes the series of adsorption and scraping actions, effectively removing iron filings. The magnetic force generating component is common knowledge and will not be elaborated on in detail.

[0019] In the above-mentioned chip liquid separator of the band saw machine, the magnetic roller is parallel to the guide roller of the filtering structure and is located on the outside or upper side of the downstream guide roller.

[0020] The magnetic roller is close to the downstream guide roller, that is, it is far away from the position where the chip liquid flows down. During the backward transportation of the iron chips, the residual chip liquid on it will flow off as much as possible. It is also set on the outside or upper side of the guide roller to ensure that it has enough time to absorb the iron chips.

[0021] As an optimization, the rotation directions of the magnetic roller and the guide roller are opposite, that is, the magnetic surface rotates downward on the opposite side after absorbing the iron filings, which is beneficial for the scraping structure to scrape off the iron filings, and also convenient for the scraping structure to guide the iron filings to the subsequent device after scraping them off.

[0022] In the above-mentioned chip liquid separator of the band saw machine, the scraper structure includes a scraper plate arranged on the base, the scraper plate is arranged at an angle, the scraper end is formed at the upper end of the scraper plate, and the scraper plate is provided with a clamping structure that makes the scraper end have a tendency to come into contact with the magnetic surface.

[0023] The scraping end of the scraper plate is in contact with the magnetic surface. When the magnetic surface passes by with iron chips, the scraper end can scrape off the iron chips. The scraper plate tilts downward, and the iron chips will fall onto the scraper plate after being scraped off. The scraper plate will guide the iron chips downward to the corresponding collection structure. The pressing structure is used to ensure that the scraper end is in contact with the magnetic surface, ensuring a good iron chip scraping effect.

[0024] In the above-mentioned chip liquid separator of the band saw machine, the scraper plate includes a fixed scraper plate fixed on the base and a movable scraper plate slidably connected to the upper end of the fixed scraper plate, the clamping structure includes a clamping spring arranged between the fixed scraper plate and the movable scraper plate, and the upper end of the movable scraper plate is formed with the scraper end, and the scraper end is tightly attached to the magnetic surface.

[0025] The fixed scraper is fixedly set, and the movable scraper can be output forward. The compression spring of the compression structure is used to apply the elastic force required for the movable scraper to extend toward the magnetic roller, ensuring that the scraping end of the movable scraper is always in contact with the magnetic surface.

[0026] As an optimization, the scraper plate is located on the side of the magnetic roller away from the filtering structure. The scraper plate is a trapezoid with a larger upper portion and a smaller lower portion, and side baffles are provided on both sides. The lower end of the scraper plate forms a chip liquid outlet.

[0027] The scraper plate is located on the opposite side of the filtering structure. The magnetic surface absorbs the iron chips and rotates downward through the scraper plate. The iron chips are scraped off and fall onto the scraper plate. The scraper plate is a trapezoid with a side baffle, which can retract the channel for the backward output of the iron chips inward, which is conducive to the docking of the chip liquid output port and the subsequent iron chip receiving assembly.

[0028] As an optimization, the front end of the movable scraper is provided with a wear-resistant portion to increase wear resistance.

[0029] In the above-mentioned chip liquid separator of the band saw machine, the upper opening of the liquid receiving box is open, and a number of flow-stabilizing ribs are evenly arranged on the inner bottom surface of the liquid receiving box. A liquid outlet is provided on the side wall of the liquid receiving box, and the liquid outlet is located on the side of the flow-stabilizing rib.

[0030] The upper opening of the liquid receiving box is connected to the bottom of the filter surface. After filtering on the filter surface, small iron chips may leak out. The small iron chips are mixed with the cutting liquid and enter the liquid receiving box. The flow-stabilizing ribs arranged at the bottom of the liquid receiving box are used to reduce the fluidity of the internal liquid, which is particularly conducive to the stable sedimentation of small iron chips at the bottom of the box. The liquid outlet is arranged on the side wall to avoid the discharge of liquid with small iron chips. The liquid outlet is located on the side of the flow-stabilizing rib to prevent small iron chips from moving toward the liquid outlet.

[0031] In the above-mentioned chip liquid separator of the band saw machine, a magnet is also placed on the inner bottom surface of the liquid receiving box.

[0032] The magnet can be used to further absorb the small iron chips in the liquid receiving box, thereby improving the purity of the recovered cutting liquid, and also has the function of separating the iron chips.

[0033] As an optimization, the liquid receiving box is square, the magnet is a magnetic rod, and the length of the magnetic rod is perpendicular to the length of the flow-stabilizing rib. The side wall of the base is provided with an access opening for pulling out the magnetic rod, and a access rope is connected to the magnetic block, the other end of which passes through the access opening.

[0034] The liquid receiving box is square, and the magnetic block is a rod-shaped object adapted to it. The magnetic rod moves in the liquid receiving box to absorb the small iron filings at the bottom of the box as much as possible. A pick-up and release port is provided on the base, and a pick-up and release rope is connected to the magnetic rod. The pick-up and release rope is used to pull the magnetic rod out of the pick-up and release port. After the magnetic rod is pulled out, the small iron filings adsorbed on it can be separated.

[0035] In the above-mentioned chip-liquid separator of the band saw machine, a diversion funnel with a larger top and a smaller bottom is provided between the sawing station and the filtering structure. The diversion funnel is fixed on the base, and the output port below the diversion funnel is connected to the top of the filtering surface.

[0036] The upper end of the diversion funnel is connected to the bottom of the sawing station, and the lower end is connected to the filter surface. It is used to collect the cutting liquid and iron chips in the sawing process and guide them to the filter surface for output.

[0037] As an optimization, the diversion funnel includes a funnel portion and an extension tube arranged below the funnel portion. The lower end of the extension tube is in contact with the filter surface, and a clearance gap is provided on the side of the extension tube near the downstream of the filter surface. The lower end of the extension tube is provided with a wear-resistant portion.

[0038] The funnel receives the cutting liquid and iron chips from the sawing process through the large opening at its upper end. The extension tube below is used to guide and transport them to the filter surface. The bottom of the extension tube is in contact with the filter surface to prevent the cutting liquid and iron chips from falling onto the filter surface and splashing out. The wear-resistant part in between is used to improve wear resistance. A clearance gap is set on one side of the extension tube to ensure that the filter surface is smoothly transported backward with the iron chips.

[0039] As an optimization, a baffle rod is provided in the extension tube, which is mainly used to prevent the cut material from falling in, and the baffle rod is horizontally arranged in the through cavity of the extension tube.

[0040] Baffles are set between the extension tube and the funnel part. The baffles are evenly arranged to prevent materials from accidentally falling into the diversion funnel and continuing to fall to damage subsequent structures, such as falling onto the filter surface and damaging the filter conveyor belt. Of course, the spacing between the baffles is relatively large and does not affect the passage of iron chips.

[0041] As an optimization, the interior of the base is hollow, forming an installation cavity, and the chip liquid separator is arranged in the installation cavity; a funnel installation port is provided above the base, and the diversion funnel is clamped in the funnel installation port; an observation port is provided on the side wall of the base, and the observation port is located on the outside of the chip liquid separator, and the switch is controlled by the observation port switch door assembly.

[0042] The chip-liquid separator is housed within the base's mounting cavity, shielded from the outside world and preventing operator interference. This provides increased safety, aesthetics, and a compact design. An observation port is provided on the base's sidewall for convenient observation of the interior, particularly the operation of the chip-liquid separator. This port is controlled by a door assembly, which is common knowledge and will not be discussed in detail.

[0043] Compared with the prior art, the present invention has the following advantages:

[0044] 1. The chip liquid separator of the present invention is mainly used to separate the chip liquid and iron chips and output them in a classified manner to realize the recycling of the chip liquid and the collection of iron chips. The filtering structure is docked below the sawing station. During the sawing process, the chip liquid and the fallen iron chips are separated into solid and liquid after passing through the filtering surface. The filtered chip liquid flows into the liquid receiving box of the receiving structure below, and the iron chips remain on the filtering surface. The magnetic attraction structure has a magnetic attraction surface with magnetism, which is close to the filtering surface for absorbing the iron chips thereon. The scraping structure is used to scrape off the iron chips on the magnetic attraction surface, and the scraped iron chips can be collected by the corresponding iron chip receiving assembly.

[0045] 2. The filtering structure is essentially a conveyor belt. The filter conveyor belt of the conveyor belt has a mesh and has a filtering function. The filter conveyor belt is wound around the guide roller. The filter drive motor drives the guide roller to rotate, and then drives the filter conveyor belt to rotate. While filtering, the filtered iron chips are transmitted to the rear to facilitate the magnetic structure at the rear to absorb the iron chips.

[0046] 3. A magnetic surface is formed on the outer wall of the magnetic roller, and the internal magnetic force generating component is used to generate magnetic force so that iron filings can be adsorbed on the magnetic surface. The magnetic drive motor drives the magnetic roller to rotate, so that the magnetic surface adsorbing the iron filings cooperates with the scraping structure to scrape off the iron filings. After scraping off the iron filings, the magnetic surface rotates to a position that cooperates with the filtering structure to continue adsorbing the iron filings. This cycle realizes a series of actions of adsorption and scraping, effectively removing the iron filings.

[0047] 4. The upper opening of the liquid receiving box is connected to the bottom of the filter surface. After filtering on the filter surface, small iron chips may leak out and mix with the cutting liquid into the liquid receiving box. The flow-stabilizing ribs on the bottom of the box are used to reduce the fluidity of the internal liquid, which is particularly conducive to the stable sedimentation of small iron chips at the bottom of the box. The liquid outlet is set on the side wall to avoid the discharge of small iron chip sediment. The liquid outlet is located on the side of the flow-stabilizing rib to prevent small iron chips from moving toward the liquid outlet.

[0048] 5. The top end of the diversion funnel docks below the sawing station, while the bottom end docks the filter surface. This funnel collects the cutting fluid and iron chips from the sawing process and directs them toward the filter surface. The bottom of the extension tube abuts the filter surface to prevent the cutting fluid and iron chips from falling onto the filter surface and splashing outward. The wear-resistant portion between them improves wear resistance, and a clearance notch is provided on one side of the extension tube to ensure smooth backward transport of the iron chips from the filter surface.

DETAILED DESCRIPTION

[0054] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0055] Specific implementation examples Figure 1-4 As shown, the chip liquid separator of the band saw is arranged on the base 11 of the saw machine 1 and is located below the sawing station 17, and includes:

[0056] A filter structure 41 , wherein the filter surface 45 of the filter structure 41 is located below the sawing station 17 ;

[0057] A magnetic structure 42 , wherein a magnetic surface 46 of the magnetic structure 42 is close to the filter surface 45 and is used to absorb iron filings;

[0058] A scraping structure 43, wherein a scraping end 52 of the scraping structure 43 is connected to the magnetic surface 46 for scraping off iron chips;

[0059] The material receiving structure 44 includes a liquid receiving box 47 disposed below the filter surface 45 .

[0060] Specifically, the chip liquid separator of the present invention is mainly used to separate the chip liquid and iron chips and output them in a classified manner to achieve the recycling of the chip liquid and the collection of iron chips. The filtering structure 41 is connected to the bottom of the sawing station 17. During the sawing process, the chip liquid and the fallen iron chips are separated into solid and liquid after passing through the filtering surface 45. The filtered chip liquid flows into the liquid receiving box 47 of the receiving structure 44 below, and the iron chips remain on the filtering surface 45. The magnetic structure 42 has a magnetic surface 46 with magnetic properties. The magnetic surface 46 is close to the filtering surface 45 for absorbing the iron chips thereon. The scraping structure 43 is used to scrape off the iron chips on the magnetic surface 46. The scraped iron chips can be collected by the corresponding iron chip receiving component, or even spilled on the ground for subsequent cleaning and collection.

[0061] like Figure 2As shown, the filter structure 41 includes two guide rollers 48 rotatably connected to the base 11. A filter conveyor belt 49 is wound around the guide rollers 48. One of the guide rollers 48 is in driving connection with the output end of the filter drive motor. The filter conveyor belt 49 is arranged horizontally, with a filter surface 45 formed on its upper side. The magnetic structure 42 is located downstream of the filter surface 45.

[0062] Specifically, the filter structure 41 is essentially a conveyor belt, and its filter conveyor belt 49 has a mesh and performs a filtering function. The filter conveyor belt 49 is wound around a guide roller 48. The filter drive motor drives the guide roller 48 to rotate, thereby driving the filter conveyor belt 49 to rotate. This achieves the purpose of simultaneously filtering and conveying the filtered iron chips backward, facilitating the magnetic attraction structure 42 at the rear to absorb the iron chips. The filter conveyor belt 49 is arranged horizontally to ensure that the chip liquid can flow directly downward, avoiding the problem of diverting the flow to the lower side and making it difficult to receive. It also helps to keep the filtered iron chips on the filter conveyor belt 49 and stably transport them backward.

[0063] like Figure 2 As shown, the magnetic structure 42 includes a magnetic roller 50 rotatably connected to the base 11. A magnetic force generating assembly is housed within the magnetic roller 50. A magnetic surface 46 is formed on the outer wall of the magnetic roller 50. The magnetic roller 50 is drivingly connected to the output end of the magnetic drive motor. The magnetic roller 50 is parallel to the guide roller 48 of the filter structure 41 and is located downstream of the guide roller 48. The magnetic roller 50 and the guide roller 48 rotate in opposite directions.

[0064] Specifically, a magnetic surface 46 is formed on the outer wall of the magnetic roller 50. An internal magnetic force generating assembly generates a magnetic force that attracts iron chips of all sizes to the magnetic surface 46. A magnetic drive motor drives the magnetic roller 50 to rotate, causing the magnetic surface 46, which has attracted the iron chips, to cooperate with the scraper structure 43 to scrape off the chips. After scraping off the chips, the magnetic surface 46 rotates to a position that mates with the filter structure 41 to continue attracting the chips. This cycle completes the adsorption and scraping process, effectively removing the chips. The magnetic roller 50 is located near the downstream guide roller 48, meaning it is farther from where the cutting fluid flows. This minimizes the amount of residual cutting fluid on the roller during the backward conveyance of the chips. Furthermore, the magnetic roller 50 is positioned outside the guide roller 48, ensuring it has ample time to absorb the chips. After attracting the chips, the magnetic surface 46 rotates downward on the opposite side, facilitating scraping off the chips by the scraper structure 43 and guiding them to subsequent equipment.

[0065] like Figure 2As shown, the scraper structure 43 includes a scraper plate 51 disposed on the base 11. The scraper plate 51 is inclined, and a scraper end 52 is formed at the upper end of the scraper plate 51. The scraper plate 51 is provided with a clamping structure that causes the scraper end 52 to have a tendency to contact the magnetic surface 46. The scraper plate 51 includes a fixed scraper plate 53 fixed to the base 11 and a movable scraper plate 54 slidably connected to the upper end of the fixed scraper plate 53. The clamping structure includes a compression spring disposed between the fixed scraper plate 53 and the movable scraper plate 54. The scraper end 52 is formed at the upper end of the movable scraper plate 54, and the scraper end 52 is closely contacted with the magnetic surface 46. The scraper plate 51 is located on the side of the magnetic roller 50 away from the filtering structure 41. The scraper plate 51 is a trapezoidal shape with a larger upper portion and a smaller lower portion, and is provided with side baffles 55 on both sides. The lower end of the scraper plate 51 forms a chip liquid outlet 65, which is connected to the iron chip packer.

[0066] Specifically, the scraping end 52 of the scraper 51 is in contact with the magnetic surface 46. When the magnetic surface 46 carries iron filings, the scraping end 52 scrapes them off. The scraper 51 tilts downward, and the scrapings fall onto the scraper 51, where they are guided downward to the corresponding collection structure. The compression structure ensures that the scraping end 52 is in contact with the magnetic surface 46, ensuring effective scraping. The fixed scraper 53 is fixed, while the movable scraper 54 can be moved forward. The compression spring of the compression structure is used to apply the elastic force required for the movable scraper 54 to extend toward the magnetic roller 50, ensuring that the scraping end 52 of the movable scraper 54 is always in contact with the magnetic surface 46. The scraper 51 is located on the opposite side of the filter structure 41. The magnetic surface 46 attracts the scrapings as they rotate downward through the scraper 51, where they are scraped off and land on the scraper 51. The scraper 51 is trapezoidal in shape with side baffles 55, which constrict the channel through which the scrapings are discharged backwards, facilitating the connection between the cutting fluid outlet 65 and the subsequent scraper packer. The scraper packer in this embodiment serves as a scraper receiving component. Furthermore, a wear-resistant portion is provided at the front end of the movable scraper 54 to enhance wear resistance.

[0067] like Figure 2 、 3 As shown, the top of the liquid receiving box 47 is open, and a number of flow stabilizing ribs 56 are evenly arranged on the inner bottom surface of the liquid receiving box 47. A liquid outlet 57 is provided on the side wall of the liquid receiving box 47, and the liquid outlet 57 is located on the side of the flow stabilizing ribs 56. A magnet 58 is also placed on the inner bottom surface of the liquid receiving box 47.

[0068] Specifically, the upper opening of the liquid receiving box 47 is connected to the bottom of the filter surface 45. After filtering by the filter surface 45, some small iron chips may leak out and mix with the cutting liquid into the liquid receiving box 47. The flow-stabilizing ribs 56 provided at the bottom of the liquid receiving box 47 are used to reduce the fluidity of the internal liquid, which is particularly conducive to the stable sedimentation of small iron chips at the bottom of the box. The liquid outlet 57 is provided on the side wall to avoid the discharge of the liquid containing small iron chips. The liquid outlet 57 is located to the side of the flow-stabilizing ribs 56 to prevent the small iron chips from moving toward the liquid outlet 57. The magnet 58 can be used to further absorb the small iron chips in the liquid receiving box 47, thereby improving the purity of the recovered cutting liquid and also has the function of separating the iron chips.

[0069] As an optimization of this embodiment, the liquid receiving box 47 is square, and the magnet is a magnetic rod, with the length of the magnetic rod perpendicular to the length of the flow-stabilizing rib 56. A retrieval port 59 for pulling out the magnetic rod is provided on the side wall of the base 11. A retrieval rope is connected to the magnetic block, and the other end of the retrieval rope passes through the retrieval port 59.

[0070] Specifically, the liquid receiving box 47 is square, and the magnetic block is rod-shaped to adapt to it. The magnetic rod moves in the liquid receiving box 47 to absorb the small iron filings at the bottom of the box as much as possible. A pick-up and release port 59 is provided on the base 11, and a pick-up and release rope is connected to the magnetic rod. The pick-up and release rope is used to pull the magnetic rod out of the pick-up and release port 59. After the magnetic rod is pulled out, the small iron filings adsorbed on it can be separated.

[0071] As an optimization of this embodiment, a diversion funnel 60, larger at the top and smaller at the bottom, is positioned between the sawing station 17 and the filter structure 41. This diversion funnel 60 is fixed to the base 11, with the outlet below it docking above the filter surface 45. The diversion funnel 60 comprises a funnel portion 61 and an extension tube 62 disposed below the funnel portion 61. The lower end of the extension tube 62 abuts against the filter surface 45, and a clearance notch 63 is provided on the downstream side of the extension tube 62 near the filter surface 45. The lower end of the extension tube 62 is provided with a wear-resistant portion. A retaining rod 64 is positioned within the extension tube 62 to prevent cut material from falling into the filter surface. The retaining rod 64 is arranged horizontally within the through-hole of the extension tube 62.

[0072] Specifically, the upper end of the diversion funnel 60 is docked below the sawing station 17, and the lower end is docked on the filter surface 45. It is used to collect the cutting liquid and iron chips during the sawing process and guide them to the filter surface 45 for output. The funnel portion 61 receives the cutting liquid and iron chips during the sawing process through its large opening at the upper end. The extension tube 62 below is used to guide and transport them to the filter surface 45. The lower part of the extension tube 62 is in contact with the filter surface 45 to prevent the cutting liquid and iron chips from falling onto the filter surface 45 and splashing outward. The wear-resistant portion between them is used to improve wear resistance. A clearance gap 63 is provided on one side of the extension tube 62 to ensure that the filter surface 45 and the iron chips are smoothly transported backward. Baffles 64 are provided between the extension tube 62 and the funnel portion 61. The baffles 64 are evenly arranged to prevent materials from accidentally falling into the diversion funnel 60 and continuing to fall, affecting and damaging subsequent structures, such as falling onto the filter surface 45 and damaging the filter conveyor belt 49. Of course, the spacing between the baffles 64 is relatively large, which does not affect the passage of iron chips.

[0073] As an optimization of this embodiment, the base 11 is hollow inside, forming an installation cavity, and the chip liquid separator is arranged in the installation cavity; a funnel installation port 101 is provided above the base 11, and the diversion funnel 60 is clamped in the funnel installation port 101; an observation port 102 is opened on the side wall of the base 11, and the observation port 102 is located on the outside of the chip liquid separator 4, and the switch is controlled by the observation port switch door assembly 103.

[0074] Specifically, the chip liquid separator 4 is disposed within the mounting cavity of the base 11, isolated from the outside world to avoid excessive interference with the operator, which is safer and also makes the overall appearance more aesthetically pleasing and the structure more compact. An observation port 102 is provided on the side wall of the base 11 to facilitate observation of the internal conditions, particularly the operation of the chip liquid separator 4. The observation port switch door assembly 103 is used to open and close the observation port 102 when appropriate.

[0075] For illustration, the filter drive motor, the mesh of the filter conveyor belt, the magnetic force generating assembly, the magnetic attraction drive motor, the compression spring and the pick-up and release rope are not specifically shown in the figure.

[0076] Specific working principle: During the sawing process, the cutting liquid and iron chips are collected by the guide funnel 60 below, and the solid-liquid mixture flows to the filter surface 45 through the extension tube 62. The cutting liquid carries extremely fine iron chips through the filter surface 45 and flows into the liquid receiving box 47 below. The magnetic rods in the box absorb the fine iron chips; most of the ordinary iron chips remain on the filter surface 45 and are transported backward by the filter conveyor belt 49. At the end of the conveying, they are magnetically absorbed by the magnetic roller 50. The magnetic surface 46 of the magnetic roller 50 rotates with the iron chips, which are scraped off by the scraper plate 51 at the rear and guided to the iron chip packer at the rear for output.

[0077] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
