Description

Technical Field

[0001] The utility model relates to the field of sawing machines, in particular to a sawing machine debris processing structure. Background Art

[0002] Saws are usually used to cut rods into required lengths. During the process of cutting the rods, chips are generated. The fallen chips are mixed with the coolant flowing down when cutting the rods, which is difficult to clean.

[0003] For example, a "debris collection device for a band sawing machine" disclosed in Chinese patent literature has a publication number of CN210523982U, which includes a sawing machine body, a sawing table, a saw beam and a saw blade. A clamping device for clamping metal materials and a collecting device for collecting metal debris are arranged on both sides of the saw beam. The collecting device includes a material receiving box, a material storage box and a suction fan. The material receiving box is a rectangular box body which is hollow inside and open at the upper end. The material storage box is a box body which is hollow inside. A communicating pipe is arranged between the ground of the material receiving box and the side walls of the material storage box and between the suction port of the suction fan and the top of the material storage box. The material storage box is internally provided with a first baffle and a second baffle. The first baffle is fixedly connected to the bottom surface of the material storage box near the suction port, and the second baffle is fixedly connected to the top surface of the material storage box and is located behind the first baffle. The shortcoming of this patent is that it directly sucks the debris through a vacuum fan. However, since the coolant sprayed out during the cutting process of the sawing machine will mix with the debris, the debris will be difficult to be sucked away or more coolant will be sucked away together, affecting the circulation of the coolant and the recovery of the debris. Utility Model Content

[0004] The utility model aims to overcome the problem in the prior art that when a sawing machine is cutting, the debris generated will mix with the sprayed coolant, resulting in the debris being difficult to recover, and provides a sawing machine debris processing structure, which can make the debris more easily and fully recovered.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The utility model discloses a chip processing structure for a sawing machine, comprising a chip collecting groove installed below a saw blade structure, and a chip discharge port installed above a chip recovery container, wherein the position of the chip discharge port is higher than the chip collecting groove, and the chip collecting groove and the chip discharge port are connected via a chip discharge channel.

[0007] The present application transports the chips obliquely from bottom to top through the chip removal channel. During the process of transporting the chips, the coolant will not be transported to the chip removal port due to the action of gravity. Instead, the chips, being lighter, can be transported from the chip collection trough to the chip removal port and discharged into the chip recovery container.

[0008] Preferably, the debris processing structure further comprises a base and a saw blade structure, wherein the saw blade structure is provided with a cooling liquid nozzle, and the base is provided with a cooling cavity, wherein the cooling cavity and the cooling liquid nozzle are connected via a cooling liquid pipe. After the cooling liquid is sprayed out, it will fall into the base, and the falling cooling liquid can be drawn back to the cooling liquid nozzle through the cooling liquid pipe, thereby realizing the circulation of the cooling liquid.

[0009] Preferably, the debris collection groove is provided with a liquid leakage port connected to the cooling cavity. Through the liquid leakage port, the coolant falling into the debris collection groove can be dropped into the base, reducing the amount of coolant discharged along with the debris, thereby reducing the loss of coolant and the frequency of coolant replenishment, thereby improving efficiency.

[0010] Preferably, a debris collection slot cover plate is mounted on the base and abuts against the upper side of the debris collection slot. The debris collection slot cover plate can press the debris collection slot tightly, thereby preventing the debris collection slot from shaking and causing the debris to fall into the base; and preventing the debris collection slot from shaking and causing the debris to slide from the chip discharge channel.

[0011] Preferably, a closed rib is provided around the upper side of the base, so that the coolant falling on the base can be blocked by the rib to prevent the coolant from flowing down from the side of the base, thereby ensuring that the coolant can flow into the inside of the base for easy circulation.

[0012] Preferably, a filter screen is provided on the upper side of the base, and the cooling cavity is provided below the filter screen. Since some debris may also fall onto the upper side of the base, by providing a filter screen on the upper side of the base, the coolant can be filtered when it flows from the upper side of the base into the base, thereby preventing debris from falling into the base and causing the coolant pipe to be blocked by debris during the coolant circulation process.

[0013] Preferably, a coolant level gauge is provided in the base, which can detect the current coolant level, and when the coolant is lower than the set level due to loss, an alarm can be issued through a signal to prompt the operator to add coolant.

[0014] Preferably, a feed rack and a discharge rack are installed below the saw blade, the feed rack includes a feed rack reflow table tilted downward in the direction toward the debris collection slot, and the discharge rack includes a discharge rack reflow table tilted downward in the direction toward the debris collection slot. Since the feed rack and the discharge rack are located below the saw blade, part of the coolant will also fall onto the feed rack or the discharge rack during the sawing process. Through the feed rack reflow table and the discharge rack reflow table in the present application, the coolant that falls onto the feed rack or the discharge rack can be returned to the upper side of the base and further enter the interior of the base to reduce the loss of coolant.

[0015] Preferably, the saw blade structure includes a steel brush structure, and the steel brush structure is located above the debris collection groove. The steel brush structure can brush off the debris attached to the saw blade, on the one hand, to prevent the saw blade from cutting with the debris, which affects the cutting efficiency, and on the other hand, it is more convenient to recover the debris.

[0016] Preferably, a chain plate structure is provided in the chip removal channel, and the chain plate structure includes transmission chains located on both sides of the chip removal channel and a transmission plate located between the transmission chains on both sides. The chain plate structure allows the chips to be transported by the transmission plate, and during the transportation process, the chips are not easy to slide off the chip removal channel due to a certain bonding force between the chips and the transmission plate.

[0017] Therefore, the utility model has the following beneficial effects: (1) the chips are discharged through the inclined chip discharge channel. During the discharge process, the coolant in the chip collection trough cannot pass upward through the chip discharge channel due to gravity, thereby realizing the separation of the coolant and avoiding the coolant circulation ratio being too low due to the coolant being carried away; (2) the coolant that falls outside the chip collection trough, that is, the upper side of the base, can be recovered and filtered through a filter to avoid chips entering the coolant circulation; (3) the coolant that falls onto the feed rack and the discharge rack can be refluxed to further increase the coolant circulation ratio.

DETAILED DESCRIPTION

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods.

[0025] like Figure 1-5 In the embodiment shown, a sawing machine debris processing structure includes a base 1, a saw blade structure 2 is mounted on the base 1, a cooling chamber 3 is provided in the base 1, a debris collection trough 4 is installed in the cooling chamber 3, the debris collection trough 4 is located below the saw blade 5 of the saw blade structure 2, and an opening is provided on the upper side of the debris collection trough 4, and debris falls into the debris collection trough 4 from the opening. A debris recovery container 6 is installed on one side of the base 1, and the debris recovery container 6 is a debris trolley with an open upper portion. A chip discharge port 18 is installed above the debris recovery container 6, and the chip discharge port 18 discharges the debris downward into the debris recovery container 6, and the position of the chip discharge port 18 is higher than the debris collection trough 4. A chip discharge channel 7 is provided between the debris collection trough 4 and the chip discharge port 18, and the chip discharge channel 7 is inclined upward in the direction from the debris collection trough 4 to the chip discharge port 18, and its inclination angle is 45° in this embodiment, and the inclination angle can be adjusted according to the equipment size and the actual chip discharge effect.

[0026] The present application transports the chips obliquely from bottom to top through the chip removal channel 7. During the process of transporting the chips, the coolant will not be transported to the chip removal port 18 due to the action of gravity. Instead, the chips, being lighter, can be transported from the chip collecting trough 4 to the chip removal port 18 and discharged into the chip recovery container 6.

[0027] The bottom of the debris recovery container 6 is also provided with an inner filter screen, and the lower side of the filter screen is a container reflux chamber, which returns the coolant filtered out of the debris recovery container to the cooling chamber through a container reflux pipe.

[0028] The saw blade structure 2 is provided with a coolant nozzle 8, and the cooling chamber 3 is connected to the coolant nozzle 8 through a coolant pipe. In the transportation path of the coolant pipe, a driving liquid pump is also connected. The saw blade 5 includes a cutting section for contacting with the round rod to produce a cutting effect. Since the saw blade 5 is cyclically rotated during operation, the cutting section refers to a fixed section relative to the base 1, and the coolant nozzle 8 is located on the left side of the cutting section and faces the right side of the cutting section, so that the coolant can be sprayed more on the saw blade 5 being cut when it is sprayed. After the coolant is sprayed, it will fall into the base 1, and the coolant pipe can be used to draw the fallen coolant back to the coolant nozzle 8, thereby realizing the circulation of the coolant. A coolant level gauge and an automatic refilling device are also provided in the base 1. The coolant level gauge can detect the current coolant level. When the coolant is lower than the set level due to loss, an alarm can be issued through a signal to prompt the operator to replenish the coolant. The base 1 is also provided with a liquid replenishing port, which is connected to the coolant tank. When there is coolant in the coolant tank and the coolant in the base 1 is lower than the set liquid level, the coolant tank can automatically replenish the coolant into the base 1. Only when the coolant in the coolant tank is also consumed, it is necessary for personnel to manually replenish the coolant and the coolant tank. Through this method, the frequency of manual replenishment of coolant is further reduced.

[0029] The debris collection groove 4 is provided with a liquid leakage port 9 connected to the cooling chamber 3. Through the liquid leakage port 9, the coolant falling into the debris collection groove 4 can fall into the base 1, reducing the amount of coolant discharged with the debris, which is convenient for solid-liquid separation on the one hand, and reduces the loss of coolant and the frequency of coolant replenishment on the other hand, thereby improving efficiency. The liquid leakage port 9 is located on the side of the debris collection groove 4 near the bottom, and the liquid leakage port 9 is strip-shaped, and its width does not exceed 5mm, so that the debris can be prevented from leaking from the liquid leakage port 9 into the cooling chamber 3.

[0030] The base 1 is also provided with a debris collection trough cover plate 10 which abuts against the upper side of the debris collection trough 4. The upper side surface of the debris collection trough 4 is provided with a circle of upper side ribs, and the area in the middle of the upper side ribs is the opening. The debris collection trough cover plate 10 includes a bending portion and a cover plate portion, the bending portion is welded on the base 1, and an acute angle is formed between the bending portion and the cover plate portion, so that the bending portion has a certain elasticity, a certain angle is formed between the cover plate portion and the upper side rib of the debris collection trough 4, and the lower end of the cover plate portion abuts against the upper side rib of the debris collection trough 4, thereby pressing the debris collection trough 4 downward.

[0031] A closed rib 11 is provided around the upper side of the base 1. The upper end of the baffle is at least 1 cm higher than the upper side of the base 1. The rib 11 can block the coolant falling on the base 1 to prevent the coolant from flowing down from the side of the base 1, ensuring that the coolant can flow into the base 1 for easy circulation. A leakage groove is provided on the upper side of the base 1, and a filter screen 12 is installed in the leakage groove. Below the filter screen 12 is the cooling chamber 3. Since some debris will also fall to the upper side of the base 1, by providing a filter screen 12 on the upper side of the base 1, the coolant can be filtered when it flows from the upper side of the base 1 into the interior of the base 1, thereby preventing debris from falling into the interior of the base 1, resulting in the coolant pipe being blocked by debris during the coolant circulation process.

[0032] A feed rack and a discharge rack are also installed below the saw blade 5. The feed rack includes a feed rack reflow platform 13 tilted downward in the direction toward the debris collection tank 4, and the discharge rack includes a discharge rack reflow platform 14 tilted downward in the direction toward the debris collection tank 4. The inclination angles of the feed rack reflow platform 13 and the discharge rack reflow platform 14 are determined according to the actual use conditions. It is only necessary to ensure that the coolant can be successfully reflowed and the height position of the feed rack and the discharge rack is not affected. In this embodiment, the inclination angles of the feed rack reflow platform 13 and the discharge rack are both 2°, and the inclination directions of the two are opposite.

[0033] The saw blade structure 2 includes a steel brush structure 15, and the steel brush structure 15 is located above the debris collection groove 4. The steel brush structure 15 can brush off the debris attached to the saw blade 5. On the one hand, it prevents the saw blade 5 from cutting with the debris, which affects the cutting efficiency. On the other hand, it is more convenient to recover the debris. The steel brush structure 15 includes two wire wheels 16, and the two wire wheels 16 are respectively located on both sides of the saw blade 5. When the saw blade 5 moves, it needs to pass between the two wire wheels 16. When passing through the two wire wheels 16, the debris attached to the saw blade 5 can be scraped off. A debris baffle is installed on the wire wheel 16, and the debris baffle can prevent the debris from splashing to the outside.

[0034] The chip removal channel 7 is provided with a chain plate structure, which includes transmission chains located on both sides of the chip removal channel 7 and transmission plates located between the transmission chains on both sides. The chain plate structure allows the chips to be transported by the transmission plates. During the transportation process, the chips are not easy to slide down the chip removal channel 7 because there is a certain adhesion between the chips and the transmission plates. The chain plate structure includes a horizontal conveying section and an oblique conveying section. The oblique conveying section is located in the chip removal channel 7, and the horizontal conveying section is located in the chip collection trough 4. The transmission plate on the horizontal conveying section transports the chips horizontally to the lower entrance of the chip removal channel 7 and enters the oblique conveying section. Then the transmission plate on the oblique conveying section transports the chips upward to the chip removal port 18. At the connection between the chip collection trough 4 and the chip removal channel 7, a transmission chain guide wheel for changing the direction of the transmission chain is installed. A chain plate drive motor 17 for driving the chain plate structure is installed at the chip removal port 18.

[0035] During the use of the equipment, debris falls from the contact position between the saw blade 5 and the steel brush structure 15. Since the debris collection groove 4 is located below the saw blade 5, the debris mainly falls into the debris collection groove 4, and some debris falls onto the upper side of the base 1, and some debris falls onto the feed rack reflow table 13 and the discharge rack reflow table 14; similarly, the sprayed coolant will also fall to the above positions. The coolant in the debris collection groove 4 will leak out from the leakage port 9 into the cooling chamber 3 of the base 1, leaving only the debris and a small amount of coolant attached to the transmission plate, which will be discharged from the chip discharge channel 7 and the chip discharge port 18 to the debris recovery container 6. The coolant on the feed rack reflow table 13 and the discharge rack reflow table 14 will flow to the upper side of the base 1 due to the inclined surface under the action of gravity, and in the process of reflow, the debris on the feed rack reflow table 13 and the discharge rack reflow table 14 will also be flushed to the upper side of the base 1. The coolant that falls onto the upper side of the base 1 flows to the filter 12, and after being filtered by debris, it falls into the cooling chamber 3, while the debris left on the upper side of the base 1 and the filter 12 is cleaned and recovered by the operator at regular intervals. In the present application, the debris is discharged through an inclined chip discharge channel. During the discharge process, the coolant in the chip collection tank cannot pass upward through the chip discharge channel due to gravity, thereby achieving the separation of the coolant and avoiding the coolant circulation ratio being too low due to the coolant being taken away. The present application can recover the coolant that falls outside the debris collection tank, that is, the upper side of the base, and filter this part of the coolant through a filter to prevent debris from entering the coolant circulation. The present application can reflux the coolant that falls onto the feed rack and the discharge rack to further increase the coolant circulation ratio.
