Description

TECHNICAL FIELD

[0001] The present application relates to the field of machine tool accessories, in particular to a waste chip filtering device for chip removal machine. BACKGROUND

[0002] A large amount of waste chips will be generated during the cutting process of the machine tool. If the waste chips are not treated in time, it will seriously affect the processing efficiency and quality, and affect the service life of the machine tool. At present, the waste chips generated during the cutting process of the machine tool are collected and transported by the chip removal machine, and the chip removal machine is generally matched with an external cooling liquid circulating system to jointly play a role in recycling the cooling liquid. The cooling liquid mixed with waste chips will affect the cutting of the workpiece, so it is necessary to filter out the waste chips in the cooling liquid.

[0003] After searching, the patent with the patent number CN219094517U is a cooling liquid filtering device for a chain plate type chip removal machine. The horizontal settling section of the chain plate type chip removal machine includes a housing and a chain plate arranged in the housing. Its characteristics are that it further includes a first screening net, a second screening net, a third screening net, a lower water tank, an external water tank and a water pump. The first screening net is movably connected to the lower end of the housing and can cover the lower end of the housing. The lower water tank is arranged below the first screening net. The external water tank is arranged on one side of the housing and is connected together with the lower water tank in communication. The second screening net is arranged at the communication between the external water tank and the lower water tank. The third screening net is arranged inside the external water tank and divides the external water tank into two chambers. The second screening net is on the side wall of one of the chambers.

[0004] Although the above-mentioned patent can filter out the waste chips in the cooling liquid through the first screening net, the second screening net and the third screening net, when filtering and treating the waste chips, the above-mentioned patent adopts the static filtering method, which causes the filtered waste chips to stay on the screening net and cannot automatically discharge the filtered waste chips. Therefore, the mesh holes of the screening net will be blocked by the filtered waste chips, which will cause the cooling liquid to be difficult to discharge, resulting in low filtration efficiency and poor filtration effect.

DETAILED DESCRIPTION

[0034] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0035] Example: See Figure 1 、 Figure 2 and Figure 9 , a waste chip filtering device for a chip conveyor, including a bracket 1, the top of the bracket 1 is connected to an organic body 2, the body 2 is composed of a shell, a feed channel, a liquid outlet channel, a guide hopper and a mounting shell, the shell is installed at the top rear side of the bracket 1 in an inclined manner with a low front and a high back, the feed channel is embedded in the top rear side of the shell, the liquid outlet channel is embedded in the bottom front side of the shell, the liquid outlet channel is composed of an arc tube and a vertical tube, the arc tube is embedded in the bottom front side of the shell, the two vertical tubes are symmetrically installed at the bottom of the arc tube, the mounting shell is installed at the top front side of the bracket 1, and the guide hopper is installed at the mounting shell. Between the mounting shell and the shell, a conveying assembly 3 is provided on the mounting shell of the body 2. The conveying assembly 3 consists of a rotating rod, a pulley, a conveyor belt, a push plate and a motor. The two rotating rods are symmetrically connected to the mounting shell of the body 2 in a front-to-back rotation manner. The two pulleys are respectively connected to the two rotating rods. The conveyor belt is sleeved between the two pulleys. Several push plates are connected to the conveyor belt at intervals. The motor is installed on the mounting shell of the body 2, and the output shaft of the motor is connected to the rear rotating rod. The shell on the body 2 is slidably connected with a filter screen plate 4 through a slide groove, and the filter screen plate 4 is tilted with the front low and the rear high.

[0036] The filter screen 4 is a kind of filter screen that is installed at the bottom of the machine body 2, so the filter screen 4 can filter out the waste chips in the coolant.

[0037] In some preferred embodiments, see Figure 2-Figure 3 In order to prevent the waste chips from being entangled with each other and forming a clumping mass, it also includes a rotating shaft A5. The upper rear part of the shell on the body 2 is rotatably connected to the rotating shaft A5. The rotating shaft A5 is located above the filter plate 4. Two spiral blades 6 are symmetrically connected to the rotating shaft A5, and the two spiral blades 6 are in opposite directions. The spiral blades 6 are located in the shell on the body 2. Four dispersion plates 61 are connected to the lower part of the feed channel of the body 2 at intervals, and the dispersion plates 61 are inclined. The directions of the two dispersion plates 61 on the left and the two dispersion plates 61 on the right are opposite. The rear rotating rod is connected to the rotating shaft A5 through a belt transmission assembly A7. The belt transmission assembly A7 consists of two pulleys and a belt. The two pulleys are respectively connected to the rear rotating rod and the rotating shaft A5, and the belt is sleeved between the two pulleys.

[0038] In the process of the coolant mixed with waste chips falling onto the filter screen plate 4 through the feed channel of the machine body 2, the waste chips can be dispersed by the dispersion plate 61, so that the waste chips are dispersed and fall onto the filter screen plate 4, and the rotation of the rear rotating rod drives the rotating shaft A5 to rotate through the belt transmission assembly A7. The rotation of the rotating shaft A5 drives the two spiral blades 6 thereon to rotate to break up the waste chips, preventing the waste chips from being entangled with each other and clumping together, so that the waste chips are evenly dispersed on the filter screen plate 4, thereby ensuring sufficient filtrate, and further improving the filtrate efficiency and effect.

[0039] In some preferred embodiments, see Figure 4In order to avoid the waste chips still having more coolant on the surface to reduce the waste of coolant, it also includes a driving assembly, which includes two cams 8 symmetrically connected to the rotating shaft A5 and a pushing frame 9 connected to the rear side of the filter screen plate 4. The two cams 8 are located outside the shell on the body 2, and the pushing frame 9 is composed of a slide rod, a cross plate and an L-shaped rod. The four slide rods are connected to the rear side of the filter screen plate 4 at intervals, and the rear ends of the four slide rods extend out of the shell on the body 2. The cross plate is installed at the rear end of the four slide rods, and the two L-shaped rods are symmetrically connected to the front side of the cross plate, and the two L-shaped rods are respectively in contact with the two cams 8. The four slide rods are all covered with a spring A10, and the rear end of the spring A10 is connected to the rear side wall of the shell of the body 2, and the front end of the spring A10 is connected to the rear side of the filter screen plate 4.

[0040] The rotation of the rotating shaft A5 drives the cam 8 to rotate. When the longer end of the cam 8 rotates to contact the L-shaped rod on the pushing frame 9, the cam 8 continues to rotate to push the L-shaped rod on the pushing frame 9 to move forward, so that the entire pushing frame 9 moves forward, thereby pushing the filter plate 4 forward, and the spring A10 is stretched accordingly. When the shorter end of the cam 8 rotates to contact the L-shaped rod on the pushing frame 9, under the reset action of the spring A10, the filter plate 4 drives the pushing frame 9 to move backward and reset, and repeats this cycle, which can make the filter plate 4 shake back and forth repeatedly. The shaking of the filter plate 4 can quickly shake off the coolant on it, and the shaking of the filter plate 4 can make the waste chips on it vibrate, thereby shaking off the coolant on the waste chips, avoiding that the waste chips still have a lot of coolant on the surface, thereby reducing the waste of coolant, and the shaking of the filter plate 4 can quickly shake off the waste chips on it into the guide hopper on the machine tool to avoid being blocked, which can further ensure the smooth discharge of the coolant, thereby further improving the filtration efficiency and effect.

[0041] In some preferred embodiments, see Figure 5In order to prevent excessive influx of waste chips and the inability of the waste chips to fully contact the filter screen 4, a baffle A11 is also included that is connected to the front side of the feed channel of the machine body 2, and the baffle A11 is tilted with the front higher and the rear lower. The rear side of the feed channel of the machine body 2 is rotatably connected to a rotating shaft B12, and the rotating shaft B12 is connected to a baffle B13. The baffle B13 is located in the feed channel of the machine body 2, and the baffle B13 is located at the rear side of the baffle A11 and contacts the baffle A11. The right outer wall of the shell on the machine body 2 is rotatably connected to a rotating shaft C16, and the rotating shaft C 16 is located behind the rotating shaft A5, and a driving member is provided between the rotating shaft C16 and the rotating shaft A5, and the driving member includes a missing gear 18 connected to the right side of the rotating shaft A5 and a small gear 19 connected to the left side of the rotating shaft C16. The missing gear 18 can rotate to engage with the small gear 19. A pulling assembly is provided between the rotating shaft C16 and the rotating shaft B12, and the pulling assembly includes a rotating block A14 connected to the right side of the rotating shaft B12 and a rotating block B17 connected to the right side of the rotating shaft C16. The rotating block B17 is hingedly connected to a connecting rod 15, and the connecting rod 15 is hingedly connected to the rotating block A14.

[0042] The rotation of the rotating shaft A5 drives the missing gear 18 to rotate. When the missing gear 18 rotates to engage with the pinion 19, the transmission of the missing gear 18 and the pinion 19 causes the rotating shaft C16 to drive the rotating block B17 to rotate. The rotation of the rotating block B17 drives the rotating block A14 to swing downward and upward through the connecting rod 15. The downward and upward swinging of the rotating block A14 drives the rotating shaft B12 to drive the baffle B13 to swing downward and upward. The baffle B13 swings downward and disengages from the baffle A11 without blocking the feed channel of the machine body 2. The coolant mixed with waste chips falls onto the filter plate 4. After the baffle B13 swings upward, it contacts the baffle A11 and re-blocks the feed channel of the machine body 2. At this time, the missing gear 18 is disengaged from the pinion 19, so that the waste chips can be intermittently dropped onto the filter plate 4, avoiding excessive influx of waste chips, which causes the waste chips to be unable to fully contact the filter plate 4, thereby enabling more sufficient filtration.

[0043] Due to the different shapes of the waste, there may be a lot of waste accumulated thickly, which may cause the waste in the upper layer to slide down directly without touching the filter plate 4, resulting in insufficient filtrate. In order to avoid the waste in the upper layer from sliding down directly without touching the filter plate 4, resulting in insufficient filtrate, in some preferred embodiments, see Figure 6-Figure 8, also includes a rotating assembly set on the body 2, the rotating assembly includes a rotating shaft D20, a slotted connecting block 231 and a spring B233, the rotating shaft D20 is provided with two groups, the two groups of rotating shafts D20 are rotatably connected to the left and right sides of the shell on the body 2, two rotating shafts D20 are a group, and the two rotating shafts D20 in each group are arranged one in front and one in the back, and the rotating shaft D20 is located above the filter screen plate 4, and the two rotating shafts D20 corresponding to the front and back are connected through a belt transmission assembly C22, and the belt transmission assembly C22 consists of two belts The two pulleys are connected to the two corresponding rotating shafts D20 at the front and rear, and the belt is sleeved between the two pulleys. The rotating shaft A5 and the two rotating shafts D20 at the rear are connected through a belt transmission component B21. The belt transmission component B21 consists of two pulleys and a belt. The two pulleys are connected to the rotating shaft A5 and the rotating shaft D20 at the rear, and the belt is sleeved between the two pulleys. The four rotating shafts D20 are all connected with a slotted connecting block 231, and the slotted connecting block 231 is located in the shell on the body 2. The filter screen plate 4 is located above the filter screen plate 4. The slotted connecting block 231 is connected to a guide rod in the slot. A connecting plate 232 is slidably connected between the two slotted connecting blocks 231 corresponding to the left and the right. The connecting plate 232 consists of a connecting plate and two short rods. The connecting plate is connected to the two short rods. The two short rods are slidably connected to the guide rods in the slots of the two slotted connecting blocks 231 corresponding to the front and rear. A spring B233 is sleeved on the guide rod in the slotted connecting block 231. The spring B2 33 is in contact with the short rod on the connecting plate 232 and the slotted connecting block 231. Two rake plates 234 are hingedly connected between the connecting plates on the two connecting plates 232. The two rake plates 234 are arranged one in front and one behind. A torsion spring 235 is connected between the rake plates 234 and the connecting plates on the connecting plates 232. The inner walls on both sides of the shell on the body 2 are connected to the limit plates 24. The limit plates 24 are located on the lower side of the connecting plates 232. The inner top of the shell on the body 2 is connected to two limit rods 25. The two limit rods 25 are arranged one in front and one behind.

[0044] The rotation of the rotating shaft A5 drives the rotating shaft D20 on the rear side to rotate through the belt transmission component B21, and the rotation of the rotating shaft D20 on the rear side drives the rotating shaft D20 on the front side to rotate through the belt transmission component C22. The rotation of the rotating shaft D20 drives the slotted connecting block 231 to rotate. When the slotted connecting block 231 rotates downward, the guide rod therein pushes the short rod on the connecting plate 232 to move downward, so that the entire connecting plate 232 moves downward, thereby causing the rake plate 234 to move downward. When the connecting plate 232 moves downward to contact the limit plate 24, the connecting plate 232 is supported by the limit plate 24 and cannot move downward further, thereby preventing the connecting plate 232 from driving the rake plate 234 to move downward excessively, and the slotted connecting block 231 drives the guide rod therein to continue to rotate downward to compress the spring B233, and when the slotted connecting block 231 rotates backward, the connecting plate 232 drives the rake plate 234 to move backward. When the slotted connecting block 231 rotates upward When the rake plate 234 is disengaged from the limit rod 25, the rake plate 234 can be swung back to its original position under the reset action of the torsion spring 235.

[0045] In some preferred embodiments, see Figure 9 In order to prevent the coolant from staying on the filter plate 4, an air pump 26 is also included. The air pump 26 is installed on the top of the shell on the body 2. The air pump 26 is connected to an injection pipe 27, and the injection pipe 27 extends into the shell on the body 2.

[0046] The air pump 26 works to deliver gas to the air jet pipe 27, and the air jet pipe 27 sprays the gas downward onto the filter screen plate 4 to blow the coolant off to prevent the coolant from staying on the filter screen plate 4, thereby further improving the filtrate efficiency and effect.

[0047] In some preferred embodiments, see Figure 9 In order to prevent the filtered coolant from containing relatively fine waste chips, it also includes a screen 28 that is clamped in the liquid outlet channel of the body 2. The shape of the screen 28 is arc-shaped, and the mesh of the screen 28 is smaller than the mesh of the filter plate 4. A block 29 is connected to the right side of the screen 28.

[0048] The filtered coolant can be filtered for a second time through the screen 28 to filter out fine debris in the coolant, thereby avoiding fine debris in the filtered coolant, thereby ensuring the purity of the coolant. The screen 28 can be pulled out for cleaning by pulling the block 29 to the right.

[0049] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
