DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the technical solution more clear, the technical solution is further described in detail below in conjunction with specific implementation methods. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the technical solution.

[0029] See also Figure 1-9The utility model provides a technical solution: a chip removal and coolant recovery and filtering device 35 for a machine tool, comprising a carrier 1, a cleaning device 2, a recovery device 3 and an angle adjustment device 4. The cleaning device 2 is arranged at the bottom of the carrier 1, and a driving device 5 for driving the cleaning device 2 to rotate is arranged at the top of the carrier 1. The recovery device 3 comprises a first hose 31, a second hose 32, a recovery box 33 and a fan 34; the first end of the first hose 31 is arranged in front of the carrier 1, and the first end of the first hose 31 is open, and when the opening faces the surface of the workbench, the metal debris and coolant remaining on the workbench can be directly absorbed. The first end of the second hose 32 is arranged at the rear of the cleaning device 2, and the first end of the second hose 32 is open, and when the opening faces the cleaning device 2, the scraped metal debris and the remaining coolant can be directly absorbed, and the second ends of the first hose 31 and the second hose 32 are both connected to the inside of the recovery box 33. The angle adjustment device 4 is arranged on the supporting frame 1 , and the first end of the first hose 31 is detachably connected to the angle adjustment device 4 ; the fan 34 is arranged on the recovery box 33 , and the air inlet end of the fan 34 is connected to the inside of the recovery box 33 .

[0030] When the utility model is in use, the user controls the carrier 1 to move on the surface of the machine tool workbench, the recovery device 3 works, the fan 34 exhausts air, and the metal scraps and coolant that are not attached to the workbench can be directly sucked into the recovery box 33 through the first hose 31 and collected. In order to allow the first hose 31 to absorb as much metal scraps and remaining coolant as possible, the direction of the open end of the first hose 31 can be continuously changed through the angle adjustment device 4. After the direction of the first hose 31 is changed, the angle adjustment device 4 can also limit the first hose 31 to remain stable, and the open direction will not be changed at will. At the same time, the driving device 5 works to drive the cleaning device 2 to rotate, and the user controls the carrier 1 to move, so that the cleaning device 2 is aimed at the attached metal scraps, and the carrier 1 moves from the back to the front. The cleaning device 2 can scrape off the metal scraps that are attached to the workbench during the rotation process, and this part of the metal scraps and the remaining coolant are sucked into the recovery box through the second hose 32 and collected. The first hose 31 and the second hose 32 have sufficient lengths, so the recovery box 33 does not need to change its position during the movement of the carrier 1. Therefore, the utility model can conveniently and quickly clean and recycle the metal scraps and coolant remaining on the workbench.

[0031] See also Figure 4-5The carrier 1 includes a first carrier plate 11 and a second carrier plate 12. The second carrier plate 12 is arranged at the front end of the first carrier plate 11 and is fixedly connected to the first carrier plate 11. The first carrier plate 11 is in an inverted U shape, and the second carrier plate 12 is arranged vertically and has a notch 121 at the bottom. The notch 121 corresponds to the open position of the front end of the first carrier plate 11, so the second carrier plate 12 will not prevent the metal debris from contacting the cleaning device 2. The height of the top of the second carrier plate 12 is higher than that of the first carrier plate 11. A handle is provided on the top of the second carrier plate 12. The user can drive the carrier 1 to move by holding the handle. A protective plate is provided in the middle of the handle, so that the hand can be prevented from hitting the drive device 5 when it slips out of the hand, thereby avoiding hand injuries.

[0032] See also Figure 1 , Figure 3 and Figure 8 The cleaning device 2 includes a rotating roller 21, a wire brush 22 and a first rotating shaft 23. The rotating roller 21 is arranged on the inner side of the first supporting plate 11, and the wire brush 22 is arranged on the outer surface of the rotating roller 21. The wire brush 22 has a sufficient thickness to exceed the bottom surface of the supporting frame 1, so when the supporting frame 1 moves on the workbench, the wire brush 22 can fit the surface of the workbench and contact with the adhered metal debris. There are two first rotating shafts 23, and the two first rotating shafts 23 are respectively located on both sides of the rotating roller 21. The first end of the first rotating shaft 23 is fixedly connected to the rotating roller 21, and the second end of the first rotating shaft 23 passes through the side wall of the first supporting plate 11 and extends to the outer side of the first supporting plate 11. The middle part of the first rotating shaft 23 is rotatably connected to the first supporting plate 11.

[0033] See also Figure 2 , Figure 4 and Figure 8 The driving device 5 includes a motor 51, a first gear 52, a second gear 53, a second rotating shaft 54, a first sprocket 55, a second sprocket 56 and a transmission chain 57. A first fixed plate 111 and a second fixed plate 112 are provided on the top of the first bearing plate 11. The motor 51 is fixedly connected to the first fixed plate 111, and the first gear 52 is fixedly connected to the output end of the motor 51. There are two second fixed plates 112. The second rotating shaft 54 ​​is horizontally arranged between the two second fixed plates 112, and the two ends are respectively rotatably connected to the two second fixed plates 112. The second gear 53 is fixedly connected to the middle part of the second rotating shaft 54 ​​and meshes with the first gear 52 for transmission. There are two first sprockets 55, which are respectively fixed at the two ends of the second rotating shaft 54. The two first sprockets 55 are respectively located on the outer sides of the two second fixed plates 112. There are two second sprockets 56, which are respectively fixed to the second ends of the two first rotating shafts 23. The adjacent first sprockets 55 and second sprockets 56 are connected by a transmission chain 57. The first rotating shaft 23 and the second rotating shaft 54 ​​have sufficient length, so the transmission chain 57 will not collide with the side wall of the first supporting plate 11.

[0034] The working principle of the drive device 5 for scraping off metal debris is as follows: the motor 51 starts to drive the first gear 52 to rotate, the first gear 52 drives the second rotating shaft 54 ​​to rotate through the second gear 53, the second rotating shaft 54 ​​drives the first sprocket wheels 55 on both sides to rotate simultaneously, the two first sprocket wheels 55 drive the second sprocket wheels 56 on both sides to rotate through the two transmission chains 57 respectively, the two second sprocket wheels 56 drive the rotating roller 21 to rotate together through the two first rotating shafts 23, and the wire brush 22 on its outer surface contacts the adhered metal debris and scrapes off the metal debris. When the rotating roller 21 rotates, the bottom of the rotating roller 21 moves toward the second hose 32, so the scraped metal debris can just move to the vicinity of the first end of the second hose 32, and be sucked into the inside of the recovery box through the second hose 32 for collection.

[0035] See also Figure 1 , Figure 2 and Figure 6 There are two angle adjustment devices 4, which are symmetrically arranged on both sides of the notch 121. The angle adjustment device 4 includes an adjustment plate 41, a third rotating shaft 42 and a magnetic seat 43. The adjustment plate 41 is arranged on the front side of the second bearing plate 12. A through hole 411 is arranged on the adjustment plate 41. There are two first hoses 31. The first ends of the two first hoses 31 pass through the two through holes 411 respectively. The first hoses 31 are detachably connected to the adjustment plate 41. The diameter of the through hole 411 is slightly smaller than the outer diameter of the first hose 31, so the first hose 31 can be inserted into the through hole 411 through its own elastic deformation. Due to the friction force, the first hose 31 will be restricted in the through hole 411 and cannot move at will. The first end of the third rotating shaft 42 is fixedly connected to the adjustment plate 41, the second end of the third rotating shaft 42 passes through the second bearing plate 12 and extends to the rear side of the second bearing plate 12. The middle part of the third rotating shaft 42 is rotatably connected to the second bearing plate 12, and the second end of the third rotating shaft 42 is fixedly connected to the magnetic seat 43. The second bearing plate 12 is a metal plate.

[0036] The magnetic seat 43 is magnetic, and the magnetic seat 43 is close to the rear surface of the second bearing plate 12, so it can absorb the second bearing plate 12. When it is necessary to change the direction of the first end opening of the first hose 31, the user only needs to turn the adjustment plate 41 by hand on the front side of the second bearing plate 12, and the adjustment plate 41 can drive the first end of the first hose 31 to rotate and change the direction. In this process, the adjustment plate 41 drives the third rotating shaft 42 to rotate, and the third rotating shaft 42 drives the magnetic seat 43 to rotate, and the magnetic seat 43 slides relative to the rear surface of the second bearing plate 12 while rotating. When the direction of the first end opening of the first hose 31 is changed, it is only necessary to release the adjustment plate 41, and the magnetic seat 43 can continue to absorb the second bearing plate 12, so that the first hose 31 can remain stable and can be fixed after the direction is changed. Since the user's hand only operates on the front side of the second bearing plate 12, it will not contact the driving device 5 on the rear side of the bearing plate 12, and the hand injury can be avoided when changing the direction of the first end opening of the first hose 31.

[0037] See also Figure 2 , Figure 4 and Figure 5 Two baffles 122 are provided on the rear side of the second bearing plate 12. The two baffles 122 are respectively located on both sides of the outside of the first bearing plate 11 and below the magnetic seat 43. The baffles 122 are fixedly connected to the second bearing plate 12 and the first bearing plate 11. There is no gap at all between the baffle 122 and the second bearing plate 12 and between the baffle 122 and the first bearing plate 11. Since the magnetic seat 43 is magnetic, the baffle 122 plays an isolating role, isolating the magnetic seat 43 from the workbench of the machine tool, and preventing metal debris on the workbench from being attracted and sticking to the magnetic seat 43. Rollers are provided on the bottom surface of the second bearing plate 12, so that the friction between the bearing frame 1 and the workbench of the machine tool can be reduced, so that the bearing frame 1 can be moved more conveniently.

[0038] See also Figure 3-5 and Figure 7 The carrier 1 also includes a limit frame 13, which is arranged on the rear side of the first carrier plate 11 and is detachably connected to the first carrier plate 11. A collecting hopper 6 is provided between the limit frame 13 and the first carrier plate 11, and the open end of the collecting hopper 6 faces the cleaning device 2. The first end of the second hose 32 is connected to the collecting hopper 6. The collecting hopper 6 can expand the suction range of the second hose 32. The collecting hopper 6 and the limit frame 13 are first installed together, and then the second hose 32 is connected to the collecting hopper 6, and the limit frame 13 can be installed on the rear side of the carrier 1. At this time, the position of the second hose 32 is limited by the collecting hopper 6 and the limit frame 13, so it will not move or change direction at will during the process of sucking debris. The scraped metal debris and the remaining coolant can enter the second hose 32 through the collecting hopper 6, and then enter the inside of the recycling box for collection.

[0039] See also Figure 3-5 , an inclined plate 7 is provided on the inner side of the first supporting plate 11 and between the cleaning device 2 and the collecting hopper 6, and the inclined plate 7 is detachably connected to the first supporting plate 11. The height of the first end of the inclined plate 7 is lower than the second end, and the second end of the inclined plate 7 is close to the collecting hopper 6 and is at the same height as the bottom of the collecting hopper 6. The scraped metal debris can smoothly enter the collecting hopper 6 through the inclined surface at the top of the inclined plate 7, thereby preventing the metal debris from accumulating at the edge of the bottom of the collecting hopper 6. The bottom surface of the inclined plate 7 is also provided with rollers, which cooperate with the rollers on the bottom surface of the second supporting plate 12 to make the supporting frame 1 more convenient to move.

[0040] See also Figure 3 and Fig. 9 The recovery device 3 further includes a filter device 35, which is disposed in the recovery box 33. The filter device 35 includes a positioning plate 351 and a filter screen 352, wherein the positioning plate 351 is disposed on the inner side wall of the recovery box 33 and is detachably connected to the inner side wall of the recovery box 33. The filter screen 352 is disposed at the bottom of the positioning plate 351 and is detachably connected to the positioning plate 351. The filter screen 352 and the positioning plate 351 are combined to form a box-shaped structure, and the second end of the first hose 31 and the second end of the second hose 32 both pass through the filter screen 352 and extend into the inner side of the filter device 35. The metal debris and coolant sucked by the first hose 31 and the second hose 32 will be discharged into the inner side of the filter 352. Since the filter 352 and the positioning plate 351 are combined into a box-shaped structure, the metal debris and the coolant will be filtered in the filter device 35. The metal debris will remain on the filter 352, and the coolant will drip downward through the filter 352. At this time, the metal debris and the coolant are separated.

[0041] See also Figure 3 The recovery device 3 further includes a liquid collecting box 36, which is disposed in the recovery box 33 and below the filter device 35. The liquid collecting box 36 is detachably connected to the inner wall of the recovery box 33. The top surface of the liquid collecting box 36 is open, and the coolant passing through the filter screen 352 will fall into the liquid collecting box 36 and be collected. Figure 1-3 The recovery box 33 is provided with a box door. When the metal scraps and coolant on the machine tool workbench are recovered, the box door can be opened, the liquid collection box 36, the positioning plate 351 and the filter screen 352 can be removed, and the collected metal scraps and coolant can be taken away and recovered.

[0042] Working principle: When the utility model is in use, the user controls the carrier 1 to move on the surface of the machine tool workbench, the recovery device 3 works, the fan 34 draws air, and the metal debris and coolant that are not attached to the workbench can be directly sucked into the recovery box 33 through the first hose 31 and collected. At the same time, the driving device 5 works to drive the cleaning device 2 to rotate, and the user controls the carrier 1 to move, so that the cleaning device 2 is aimed at the attached metal debris, and the carrier 1 moves from the back to the front. The cleaning device 2 can scrape off the metal debris attached to the workbench during the rotation process, and this part of the metal debris and the remaining coolant are sucked into the recovery box through the second hose 32 and collected.
