Description

Technical Field

[0001] This invention relates to the field of sawing technology, and more specifically, to a sawing chip removal system. Background Technology

[0002] During the operation of a band saw, a lot of chips are generated. These chips remain on the saw band, affecting the next cut and even causing the saw band teeth to break. Therefore, chip removal brushes are installed on band saws to scrape off the chips remaining on the saw band. However, the scraped chips are often mixed with coolant, and during the process of carrying the chips away, coolant is also easily carried out, resulting in waste. Furthermore, when the coolant is recycled, chips can easily remain, leading to pipe blockage. Chinese patent application number 2025108505125 discloses a band saw that facilitates the separation of cutting chips. The scraper moves laterally, causing it to press against the cutting saw blade and scrape away chips from its surface. However, the scraped chips mix with coolant, and during the process of carrying the chips away, coolant is also easily carried out, resulting in waste. During coolant recycling, chips remaining in the coolant can easily cause blockage. Summary of the Invention

[0003] To overcome the above shortcomings, the present invention provides a sawing machine chip removal system, which has a good chip removal effect on the saw belt, a good separation effect between chips and coolant, and the coolant is not easily carried away by the chips. When the coolant is recycled, the chips are not easily left in the coolant.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a sawing machine chip removal system, including a chip removal wheel set on the saw frame, a saw blade installed on the saw frame, the chip removal wheel abutting against the saw blade, a chip storage groove set below the chip removal wheel, the chip storage groove being connected to a chip lifter, the chip lifter lifting the chips from the chip storage groove upwards and discharging them outside the sawing machine, and a drainage hole being provided on the side wall of the chip storage groove.

[0005] During the sawing process, the saw blade rotates and sprays coolant onto it. After leaving the bar stock, the saw blade passes through a chip remover wheel, which engages with the saw blade to remove residual chips, which fall into a chip collection trough. Both chips and coolant enter the chip collection trough, which is connected to a chip lifter. The chip lifter raises the chips from the chip collection trough and discharges them outside the saw. During this lifting process, the coolant flows downwards into the chip collection trough due to gravity. Since the density of the chips is greater than that of the coolant, the chips sink to the bottom and separate from the coolant. The coolant is then filtered through a drain hole and returned to the storage tank for recycling. The chip remover wheel effectively removes chips from the saw blade, and the chips and coolant are automatically separated by gravity and then filtered through the drain hole, resulting in good separation and minimizing chip residue in the coolant, thus facilitating coolant recycling. As the chip lifter raises and discharges the chips from the chip storage tank, the coolant flows downwards into the chip storage tank due to gravity. The coolant is not easily carried away by the chips, thus avoiding waste.

[0006] Preferably, a pair of chip removal wheels are provided, and a bracket is provided on the saw frame. The chip removal wheels are installed on the saw frame, and the two chip removal wheels are respectively placed on both sides of the saw blade.

[0007] Both sides of the saw blade have chip removal wheels for chip removal, improving the chip removal effect.

[0008] Preferably, a connecting plate with two adjustable angles is installed on the bracket, and a drive motor is installed on the connecting plate. The output shaft of the drive motor is connected to the chip removal wheel.

[0009] The drive motor rotates the chip removal wheel, resulting in excellent chip removal. The angle of the connecting plate is adjustable to ensure reliable contact between the chip removal wheel and the saw blade, guaranteeing effective chip removal.

[0010] Preferably, an air curtain chip removal seat is installed on the bracket, with an air inlet chamber inside the air curtain chip removal seat and an air curtain slot connected to the air inlet chamber on the air curtain chip removal seat. The air curtain slot blows air towards the saw blade to form an air curtain.

[0011] High-pressure airflow is delivered into the air inlet cavity, and the airflow is blown from the air curtain slot onto the surface of the saw blade, thereby further blowing away the chips remaining on the surface of the saw blade and improving the chip removal effect.

[0012] Preferably, a workbench is installed below the saw frame, and the surface of the workbench is sunken to form a chip storage trough.

[0013] The workbench surface is lowered to form a chip collection trough, ensuring that the chip collection trough is at a low position, and the edge coolant and chips flow into the chip collection trough for collection.

[0014] Preferably, a protective panel is installed around the edge of the workbench surrounding the chip storage trough, a door panel is installed in front of the protective panel, a window is installed on the right side of the protective panel, the upper part of the chip elevator passes through the window, and inclined guide plates are installed between the chip storage trough and the door panel, as well as between the chip storage trough and the window.

[0015] The protective enclosure blocks chips and coolant, preventing them from splashing outwards. The inclined guide vanes direct the flow of chips and coolant into the chip reservoir.

[0016] Preferably, a feeding elevator and a chip storage box are installed outside the saw. The feed inlet at the bottom of the feeding elevator is located below the discharge outlet of the chip elevator, and the discharge outlet at the top of the feeding elevator is located above the chip storage box.

[0017] The chips are lifted upwards by the feeding elevator and stored in the chip collection box, making chip collection convenient.

[0018] Preferably, a filter plate and a guide channel are installed on the upper part of the chip collection trough. The filter plate is rotatably installed above the guide channel and is tilted. The filter plate is deflected up and down to achieve shaking.

[0019] After the chips and coolant flow into the chip collection tank, they are first filtered by a filter plate. The coolant then flows downwards into a guide channel, which directs the coolant into a storage tank for recycling. The filter plate is tilted to facilitate the downward flow of chips and coolant. As the filter plate reciprocates and vibrates, chips remaining on it fall from the lower end into the chip collection tank. During this process, most of the coolant flows into the guide channel, where chips are less likely to remain and is quickly reused. A small portion of the coolant falls with the chips into the chip collection tank, where it is separated from the chips.

[0020] Preferably, a chip-pushing screw is installed on the filter plate, and the chip-pushing screw is connected to a rotating sleeve. A pull rope is wound around the rotating sleeve. One end of the pull rope is connected to the chip storage trough through a tightening spring, and the other end of the pull rope is directly connected to the chip storage trough. A ratchet mechanism is installed between the rotating sleeve and the chip-pushing screw to realize the unidirectional rotation of the chip-pushing screw.

[0021] During the reciprocating up-and-down deflection of the filter plate, the pull rope winds around the rotating sleeve, enabling the rotating sleeve to rotate. A ratchet mechanism is installed between the rotating sleeve and the chip-pushing screw, thereby realizing the unidirectional rotation of the chip-pushing screw, which in turn pushes the chips on the filter plate downwards, which helps to accelerate the falling speed of the chips and prevent chip accumulation.

[0022] In another embodiment, a chip pusher screw and a chip pusher motor are installed on the filter plate. The output shaft of the chip pusher motor is connected to the chip pusher screw, and an eccentric wheel is installed on the output shaft of the chip pusher motor. An abutment rod is set below the filter plate, and the outer wall of the eccentric wheel abuts against the abutment rod. The rotation of the eccentric wheel pushes the filter plate to rotate upward.

[0023] The chip pusher motor drives the chip pusher screw to rotate, which in turn pushes the chips on the filter plate downwards, accelerating the falling speed of the chips and preventing chip accumulation. Simultaneously, the chip pusher motor drives the eccentric wheel to rotate. The distal end of the eccentric wheel contacts the abutment rod, pushing the filter plate upwards. When the distal end of the eccentric wheel separates from the abutment rod, the filter plate falls back under the influence of gravity. Through the continuous rotation of the eccentric wheel, the filter plate achieves a reciprocating up-and-down rotation, thus creating a shaking effect.

[0024] Compared with the prior art, the beneficial effects of the present invention are: (1) The chip removal wheel contacts the saw blade to remove the residual chips on the saw blade, and rotating chip removal wheels are provided on both sides of the saw blade to improve the chip removal effect; (2) After the saw blade passes through the chip removal wheel, the air curtain slot blows air towards the saw blade to form an air curtain, which sweeps away the chips on the saw blade. Then, the chip removal operation of the second chip removal wheel is performed to ensure that the chips on the saw blade are completely removed; (3) The chips and coolant are automatically separated by gravity and then filtered through the drain hole. The separation effect is good, and the chips are not easy to remain in the coolant, which is conducive to the circulation of coolant. (4) During the process of the chip lifter lifting the chips from the chip storage tank upwards and discharging them, the coolant is subjected to gravity and flows downwards into the chip storage tank. The coolant is not easily carried away by the chips, thus avoiding waste. (5) After the chips and coolant flow into the chip storage tank, they are first filtered by the filter plate, and then the coolant flows downwards into the guide channel. The guide channel guides the coolant to the storage tank for recycling. The coolant is not easily left with chips and is quickly recycled. During the process of the filter plate deflecting up and down to achieve shaking, the chips left on the filter plate can easily fall into the chip storage tank from the lower end of the filter plate.

When the pushing surface 23 separates from the filter plate 17, the filter plate 17 moves downward under the action of the return spring 19 and gravity. As the cam 22 rotates continuously, the filter plate 17 vibrates up and down. A flexible closed curtain is connected between the edge of the filter plate 17 and the upper edge of the chip collection tank 9 to ensure that chips and coolant flow onto the filter plate 17. The cam 22 is rotated by a chain drive between the cam 22 and the drive sprocket on the chip lifter 10. A push rod is connected to the filter plate 17 and abuts against the outer wall of the cam 22. A clearance opening 24 is provided on the side wall of the chip collection tank 9. The filter plate 17 passes through the clearance opening 24 and is supported by the lower edge of the clearance opening 24 for positioning.

[0057] A chip-pushing screw 25 is installed on the filter plate 17, and is located on the primary filter plate 20. The chip-pushing screw 25 is connected to a rotating sleeve 26, around which a pull rope 27 is wound. One end of the pull rope 27 is connected to the chip collection trough 9 via a tension spring 28, and the other end is directly connected to the chip collection trough 9. A ratchet mechanism 29 is installed between the rotating sleeve 26 and the chip-pushing screw 25 to achieve unidirectional rotation of the chip-pushing screw 25. The ratchet mechanism 29 includes a ratchet 29 and a pawl 30. Several ratchet teeth are spaced apart on the outer wall of the ratchet 29. The ratchet 29 is mounted on the chip-pushing screw 25, and the pawl 30 is rotatably mounted on the rotating sleeve 26. A spring is installed between the pawl 30 and the rotating sleeve 26. During the reciprocating up-and-down rotation of the filter plate 17, the pull rope 27 winds around the rotating sleeve 26, enabling the rotating sleeve 26 to rotate. A ratchet 29 mechanism is installed between the rotating sleeve 26 and the chip-pushing screw 25, thereby realizing the unidirectional rotation of the chip-pushing screw 25, which in turn pushes the chips on the filter plate 17 to a lower position, which helps to accelerate the falling speed of the chips and prevent chip accumulation.

[0058] During the sawing process, the saw blade 3 rotates and sprays coolant onto it. After leaving the bar stock, the saw blade 3 passes through the chip removal wheel 2, which abuts against the saw blade 3 to remove residual chips, which then fall into the chip storage tank 9. After flowing into the chip storage tank 9, the chips and coolant are first filtered by the filter plate 17. The coolant then flows downwards into the guide channel 18, which guides the coolant to a storage tank for recycling. The filter plate 17 is tilted to facilitate the downward flow of chips and coolant. As the filter plate 17 reciprocates and vibrates, chips remaining on it fall from the lower end into the chip storage tank 9. During this process, most of the coolant flows into the guide channel 18, where chips are less likely to remain and it is quickly recycled. A small portion of the coolant falls into the chip storage tank 9 with the chips, where it is separated from them. The chip collection trough 9 is connected to the chip lifter 10. The chip lifter 10 lifts the chips from the chip collection trough 9 and discharges them outside the saw. During the lifting process, the coolant flows downward into the chip collection trough 9 under the influence of gravity. Since the density of the chips is greater than that of the coolant, the chips sink to the bottom and separate from the coolant. The coolant is filtered and separated through the drain hole, and the coolant discharged from the drain hole flows back to the storage tank for recycling. The chip removal wheel 2 removes the chips from the saw band 3, achieving a good removal effect. The chips and coolant are automatically separated by gravity and then filtered and separated through the drain hole, resulting in a good separation effect. Chips are less likely to remain in the coolant, which is beneficial for the recycling of coolant. During the process of the chip lifter 10 lifting and discharging the chips from the chip collection trough 9, the coolant flows downward into the chip collection trough 9 under the influence of gravity, preventing the coolant from being carried away by the chips and avoiding waste.

A drive motor 7 is mounted on the connecting plate 5, and the output shaft of the drive motor 7 is connected to the chip removal wheels 2. Chip removal wheels 2 on both sides of the saw blade 3 perform chip removal operations, and the drive motor 7 drives the chip removal wheels 2 to rotate, resulting in good chip removal efficiency. The angle of the connecting plate 5 is adjustable to ensure reliable contact between the chip removal wheel 2 and the saw blade 3, thus guaranteeing the chip removal effect.

[0060] A chip collection tank 9 is provided below the chip removal wheel 2. The chip collection tank 9 is connected to the chip lifter 10.

Inclined guide plates 14 are installed between the chip collection trough 9 and the door panel, and between the chip collection trough 9 and the window 13. The inclined guide plates 14 serve to guide the flow of chips and coolant into the chip collection trough 9.

[0062] A feeding elevator 15 and a chip storage box 16 are installed outside the saw. The feed inlet of the feeding elevator 15 is located below the discharge outlet of the chip elevator 10, and the discharge outlet of the feeding elevator 15 is located above the chip storage box 16.

[0063] Both the chip lifter 10 and the feeding lifter 15 are chain plate structures, and both are existing technologies. The chip lifter 10 includes a horizontal section and an inclined section. The horizontal section is placed in the chip storage trough 9, and the inclined section is located at the window 13 on the right side of the protective enclosure 12. Chains are installed on both sides of the chip lifter 10, and several chain plates are installed between the chains at intervals. The chain plates are provided with filter holes and several feeding baffles are installed at intervals on the chain plates. Drive sprockets are provided at both ends of the chip lifter 10. The chains are connected to the drive chains, and the drive sprockets are driven by a motor. Multiple transition sprockets are installed on the chip lifter 10. The transition sprockets mesh with the chains to achieve chain positioning and steering.

[0064] The feeding elevator 15 includes a receiving section and a lifting section. The receiving section is horizontally positioned, while the lifting section is inclined upwards. A hopper is installed on the receiving section, aligned with the discharge port at the top of the chip elevator 10. Chains are installed on both sides of the feeding elevator 15, with several spaced chain plates between the chains. Several feeding stops are spaced on the chain plates. Drive sprockets are installed at both ends of the feeding elevator 15, and the chains are connected to the drive chains. The drive sprockets are driven by a motor. Multiple transition sprockets are installed on the chip elevator 10, which mesh with the chains to achieve chain positioning and steering.

[0065] A filter plate 17 and a guide channel 18 are installed on the upper part of the chip collection tank 9. The filter plate 17 is rotatably mounted above the guide channel 18 and is tilted. The filter plate 17 vibrates by reciprocating up and down. The higher side of the filter plate 17 is positioned below the chip removal wheel 2. The lower end of the filter plate 17 is rotatably mounted on the guide channel 18. A return spring 19 is installed between the filter plate 17 and the guide channel 18. The filter plate 17 includes a primary filter plate 20 and a secondary filter plate 21. The primary filter plate 20 is positioned above the secondary filter plate 21, and the primary filter plate 20 and the secondary filter plate 21 are spaced apart. A flexible sealing curtain is connected between the edge of the filter plate 17 and the upper edge of the chip collection tank 9 to ensure that chips and coolant flow onto the filter plate 17. An avoidance opening 24 is provided on the side wall of the chip collection tank 9. The filter plate 17 passes through the avoidance opening 24 and is supported by the lower edge of the avoidance opening 24 for positioning.

[0066] A chip-pushing screw 25 and a chip-pushing motor 31 are installed on the filter plate 17. The chip-pushing motor 31 and the chip-pushing screw 25 are located on the primary filter plate 20. The output shaft of the chip-pushing motor 31 is connected to the chip-pushing screw 25. An eccentric wheel 32 is installed on the output shaft of the chip-pushing motor 31. An abutment rod 33 is located below the filter plate 17 and is fastened to the worktable 11. The outer wall of the eccentric wheel 32 abuts against the abutment rod 33. The rotation of the eccentric wheel 32 pushes the filter plate 17 to rotate upward. The operation of the chip-pushing motor 31 drives the chip-pushing screw 25 to rotate, thereby pushing the chips on the filter plate 17 downward, which helps to accelerate the falling speed of the chips and prevent chip accumulation. At the same time, the chip-pushing motor 31 drives the eccentric wheel 32 to rotate. The distal end of the eccentric wheel 32 contacts the abutment rod 33, pushing the filter plate 17 to rotate upward. When the distal end of the eccentric wheel 32 separates from the abutment rod 33, the filter plate 17 falls back under the action of gravity and the return spring 19. The continuous rotation of the eccentric wheel 32 enables the filter plate 17 to rotate up and down, thereby achieving a shaking effect.

[0067] During the sawing process, the saw blade 3 rotates and sprays coolant onto it. After leaving the bar stock, the saw blade 3 passes through the chip removal wheel 2, which abuts against the saw blade 3 to remove residual chips, which then fall into the chip storage tank 9. After flowing into the chip storage tank 9, the chips and coolant are first filtered by the filter plate 17. The coolant then flows downwards into the guide channel 18, which guides the coolant to a storage tank for recycling. The filter plate 17 is tilted to facilitate the downward flow of chips and coolant.

During this process, most of the coolant flows into the guide channel 18, where chips are less likely to remain and it is quickly recycled. A small portion of the coolant falls into the chip storage tank 9 with the chips, where it is separated from them. The chip collection trough 9 is connected to the chip lifter 10. The chip lifter 10 lifts the chips from the chip collection trough 9 and discharges them outside the saw. During the lifting process, the coolant flows downward into the chip collection trough 9 under the influence of gravity. Since the density of the chips is greater than that of the coolant, the chips sink to the bottom and separate from the coolant. The coolant is filtered and separated through the drain hole, and the coolant discharged from the drain hole flows back to the storage tank for recycling.

[0068] Example 5: A chip removal system for a sawing machine (see...) Figure 9Its structure is similar to any one of embodiments 1 to 4, the main difference being that in this embodiment, an air curtain chip removal seat 34 is installed on the bracket 4. An air inlet chamber is provided inside the air curtain chip removal seat 34, which is connected to a blower or a high-pressure air tank. An air curtain slot 35 communicating with the air inlet chamber is provided on the air curtain chip removal seat 34, blowing air towards the saw blade 3 to form an air curtain. Two air curtain slots 35 are provided, blowing air towards both sides of the saw blade 3. A sliding slide 36 is installed on the bracket 4, and the slide 36 is locked in place by screws. The air curtain chip removal seat 34 is rotatably mounted on the slide 36, and after rotating into place, it is locked in place by screws. The rotatable air curtain chip removal seat 34 facilitates adjustment of the air outlet angle, ensuring that the air curtain can reach the saw blade 3. After the saw blade 3 passes through a chip removal wheel 2, the air curtain slot 35 blows air towards the saw blade 3 to form an air curtain. The air curtain sweeps away the chips on the saw blade 3, and then the saw blade 3 passes through a second chip removal wheel 2 to ensure that the chips on the saw blade 3 are completely removed. Other structures are the same as any one of embodiments 1 to 4.
