[0034] Step IV, sawing the tail of the material: After completing the sampling of the sample, loosen the first clamping assembly 6 and the second clamping assembly 7, first transport the sampled material 3 to the sawing station through the production line 4, and then use the fourth clamping assembly 10 to fit and limit the cut surface, and then use the second clamping assembly 7 and the third clamping assembly 5 to clamp and fix the sampled material 3, and then use the vertical saw device 8 to saw to obtain the finished material section 3-1 and the tail of the material, and finally transport the tail of the material to the unloading station through the production line 4;

[0035] Step V, unloading of the material heads, tails and samples: the material heads, tails and samples transported to the unloading station are first pushed away from the production line 4 by the first pushing device 11, then transported by the unloading branch line 12, and finally pushed to the storage station by the second pushing device 12-1 at the tail end of the unloading branch line 12;

[0036] Step VI, unloading of finished material segments: first, the finished material segment 3-1 is transported to the rear end of the production line 4 by the production line 4, and then the finished material segment 3-1 on the production line 4 is vertically lifted by the lifting and placing trolley 1, and then the finished material segment 3-1 is moved to overlap with the unloading platform 13 by the lifting and placing trolley 1, and finally, the finished material segment 3-1 is vertically lowered to the unloading platform 13 by the lifting and placing trolley 1;

[0037] Step VII, dust removal and waste collection and processing: The dust and waste generated by sawing are collected by a bag dust removal device, and the collected dust and waste are briquetting through a briquetting device 14.

[0038] In step III, the sampling component 9 first moves and adjusts the suction cup component 17 to a preset position through the transverse movement mechanism 15 and the lifting mechanism 16, and then flips and adjusts the suction cup component 17 through the flipping mechanism 18 so that the suction cup component 17 is aligned with the cut surface of the material 3 after the material head is cut off. After the cut surface is in contact with the suction cup component 17, the sampling component 9 is adsorbed and fixed relative to the cut surface of the material 3 by extracting the air in the suction cup.

[0039] The production line 4 includes a loading section 4-1, a sawing operation section 4-2 and a unloading section 4-3 arranged in a linear manner. The loading platform 2 is correspondingly arranged on one side of the loading section 4-1, and the unloading platform 13 is correspondingly arranged on one side of the unloading section 4-3.

[0040] As a preferred embodiment, the loading platform 2 and the unloading platform 13 both include two parallel strip-shaped block-shaped tabletops, the two strip-shaped block-shaped tabletops are respectively supported at the two ends of the material block, and the running track of the lifting and placing trolley is arranged on the symmetrical axis of the two block-shaped tabletops, so that the lifting and placing trolley can stably lift or put down the material from below the material, and the end of the running track of the lifting and placing trolley extends to the bottom of the production line 4, so that the lifting and placing trolley can overlap with the production line, and then the fixed-length lifting mechanism is used for stable lifting. The fixed-length lifting mechanism is lifted and lowered through the gap 1-2 to correspond to the upper and lower sides of the production line surface, thereby lifting the material from the production line or leaving the material on the production line;

[0041] As a preferred embodiment, the fixed-length lifting mechanism includes a support block, which is driven to rise and fall by a cylinder. Two fixed-length lifting rods are arranged on the bottom surface of the support block. The fixed-length lifting rods are provided with tooth grooves extending along the rod direction. The tooth grooves are meshed with fixed-length gears. The two fixed-length gears rotate coaxially, so that the two fixed-length lifting rods are lifted and lowered synchronously, thereby maintaining the lifting and lowering stability of the support block.

[0042] The sawing operation section 4-2 is provided with the first clamping assembly 6, the second clamping assembly 7, the third clamping assembly 5 and the fourth clamping assembly 10 arranged in sequence, and the sawing operation section 4-2 is also provided with a narrow slit 8-2 for the saw blade 8-1 of the vertical saw device 8 to move through, the first clamping assembly 6 and the second clamping assembly 7 are located in front of the narrow slit 8-2, and the third clamping assembly 5 and the fourth clamping assembly 10 are located in the rear of the narrow slit 8-2;

[0043] Among them, the first clamping assembly 6, the second clamping assembly 7, the third clamping assembly 5 and the fourth clamping assembly 10 have the same structure, and all include two clamping blocks that are arranged to move relative to each other. The sawing operation section 4-2 is provided with a guide groove for the clamping block to move, and the two guide grooves extend from the two side edges of the sawing operation section 4-2 to the middle in the direction perpendicular to the edge; the distance between the front side end face of the third clamping assembly and the narrow slit is set according to the preset material head sawing length, and the distance between the front side end face of the fourth clamping assembly and the narrow slit is set according to the preset finished material section sawing length. The first clamping assembly 6 and the second clamping assembly 7 are arranged according to the clamping function that can play a clamping role during the sawing process. The positions are flexibly arranged; when sawing the head of the material, the two clamping blocks of the third clamping assembly are driven inward in advance to form a baffle structure for limiting the position, and the front end face of the third clamping assembly is fitted with the end face of the material to limit the position and fix the length, and then the two clamping blocks of the first clamping assembly 6 and the second clamping assembly 7 are driven inward to clamp on the two side surfaces of the material, so as to clamp and fix, thereby ensuring the accuracy and stability of sawing the head of the material; similarly, when sawing the tail of the material, the fourth clamping assembly plays the role of limiting the position and fixing the length, and the second clamping assembly and the third clamping assembly play the role of clamping and fixing, thereby ensuring the accuracy and stability of sawing the tail of the material, thereby ensuring the quality of the finished material section.

[0044] The first pushing device 11 is arranged at the front side of the fourth clamping assembly 10, and the first pushing device 11 is arranged to move toward the extension direction of the discharge branch line 12, and the discharge branch line 12 is arranged perpendicular to the sawing operation section 4-2. The tail end of the discharge branch line 12 is provided with the second pushing device 12-1, and the second pushing device 12-1 is arranged to move perpendicular to the direction of the discharge branch line 12;

[0045] The production line area corresponding to the first pushing device is the unloading station. The unloading station is set in front of the fourth clamping component 10, and the material head, material tail and sample transported to the unloading station can be intercepted by the fourth clamping component to facilitate the accurate pushing of the first pushing device, and push the material head, material tail and sample on the unloading station to the unloading branch line.

[0046] The sampling assembly 9 includes the transverse movement mechanism 15, which is located at one side of the sawing operation section 4-2. The transverse movement mechanism 15 is arranged to be laterally movable on the line connecting the first pushing device 11 and the narrow slit 8-2. The transverse movement mechanism 15 is provided with a lifting mechanism 16, and the lifting mechanism 16 is rotatably provided with the flipping mechanism 18. The flipping mechanism 18 is fixedly provided with the suction cup assembly 17, and the suction cup assembly 17 is horizontally mounted above the sawing operation section 4-2.

[0047] The flip mechanism 18 includes a rotating shaft 18-1, which is arranged parallel to the narrow slit 8-2, and the end of the rotating shaft 18-1 is rotatably arranged relative to the end surface of the lifting mechanism 16;

[0048] The suction cup assembly 17 includes a plurality of suction cups 17-1, the back side of the suction cup 17-1 is connected to an exhaust pipe 17-2, the exhaust pipe 17-2 is connected to an exhaust device through a hose, the exhaust pipe 17-2 is fixed relative to the rotating shaft 18-1 through a bracket 17-3, and the plurality of suction cups 17-1 are relatively distributed on both sides of the rotating shaft 18-1, and the ports of the plurality of suction cups 17-1 are flush with each other;

[0049] Before taking samples, the suction cup port plane is adjusted to be flush with the narrow slit 8-2. When the suction cup port fits the end face of the material, the air in the suction cup is extracted by the vacuum equipment and the production line is continuously pushed. When the suction cup is completely flat and attached to the end face of the material, the end of the material just passes a certain length beyond the narrow slit, which plays a role in fixing the thickness of the sample. After being cut by the vertical saw device, the part adsorbed on the suction cup is the sample. Subsequently, the cylinder drives the rotating shaft to flip, so that the sample is flipped parallel to the plane of the production line, and then the transverse movement mechanism drives the sample to the unloading station. By reversely inflating the inside of the suction cup, the sample is detached from the suction cup, and then the unloading process is carried out. In addition, the flipping mechanism and the suction cup assembly are lifted by the lifting mechanism 16 to facilitate the normal passage of subsequent finished product sections.

[0050] The saw blade 8-1 includes a vertical section 8-3 corresponding to the narrow slit 8-2, and a mounting block 19 is arranged near the upper end of the vertical section 8-3. A U-shaped groove 19-1 for accommodating the vertical section 8-3 is correspondingly arranged on the mounting block 19. An atomizing nozzle 20 is correspondingly arranged on the groove walls on both sides of the U-shaped groove 19-1. The atomizing nozzle 20 is used to spray oil mist. An oil collecting hood 21 is arranged corresponding to the cover on the outer side of the mounting block 19. The inner cavity of the oil collecting hood 21 is connected to the oil collecting tank through a pipeline; a dust collecting funnel 22 is arranged at the lower end of the vertical section 8-3, and the dust collecting funnel 22 is connected to the bag dust removal device through a pipeline;

[0051] As a preferred embodiment, the atomizing nozzle sprays oil mist from the direction of the saw teeth at a certain angle to the side end face of the saw blade, and the mounting block is movably arranged along the length direction of the saw blade by a cylinder drive; when the vertical saw device performs sawing operation, the mounting block is fixed and maintained at the top of the vertical section of the saw blade, and the atomizing nozzle sprays in a conical mist structure, so that the oil mist is sprayed evenly, and a thin oil layer can be formed on the end faces of both sides of the saw blade. At the same time, the nozzles on both sides alternately sweep up and down, which can ensure that the oil mist particles can better cover the tooth edges of the saw teeth during the high-speed operation of the saw blade, so as to obtain a better lubrication effect. At this time, the oil mist temperature is adjusted by the temperature sensor feedback of the saw blade surface. When the saw blade temperature is within the normal temperature rise range, the atomizing nozzle calls the oil of the conventional cooling temperature to cool the saw blade to ensure normal sawing operation. When the saw blade temperature rises abnormally, the super-cold oil is called to achieve rapid cooling of the saw blade, and at the same time, an abnormal temperature alarm feedback is made to trigger the emergency braking of the vertical saw device to ensure production safety.

[0052] When the vertical saw device completes a work progress and returns to the starting position, the saw blade continues to run at high speed while waiting for the work progress to move down. At this time, the mounting block is driven by the cylinder to make regular up and down reciprocating motions. The atomizing nozzle sprays upward in a flat conical mist structure, and the oil mist sprayed on both sides is focused on the same straight line as the saw blade surface, forming a high-pressure oil mist similar to a shovel on the saw blade surface. When the mounting block moves from bottom to top, the high-pressure oil mist with concentrated impact force scrapes the waste chips adsorbed on the saw blade surface, and forms a small stream of flowing oil on the saw blade surface, driving the scraped waste chips to slide downward, and finally drip into the dust collecting funnel below for subsequent processing. Combined with the high-speed circulation operation of the saw blade, the continuous cleaning of the saw blade surface can be guaranteed, and the debris particles on the saw blade surface can be prevented from affecting the quality of the saw cut surface, and the impact on the vertical saw device itself can be avoided, thereby improving the service life of the vertical saw device and the saw blade.

[0053] The lubricating oil is sprayed in the form of oil mist onto the end faces of both sides of the saw blade through the atomizing nozzles on both sides, so as to achieve the effect of lubrication and cooling. At the same time, compared with directly using the oil to flow on the surface of the saw blade, the oil mist refueling method is more fuel-efficient. At the same time, the oil collecting hood installed on the outside can prevent the oil mist from diffusing in the air. The oil is collected and pumped back into the oil collecting tank through the fan pipe for repeated use, which produces certain economic benefits. A dust collecting funnel is set at the lower end, which can move with the saw blade and catch the waste chips dropped during the sawing process.

[0054] The dust outlet of the bag dust removal device is connected to the briquetting device 14, and the briquetting device 14 includes two molding cavities 23. The ports on one side of the two molding cavities 23 correspond to the briquetting 24 and the push plate 25 alternately by moving, and the ports on the other side of the two molding cavities 23 correspond to the pressure plate 26 alternately by moving. The briquetting 24 is arranged to move in the direction of the pressure plate 26. There are two push plates 25, which are symmetrically arranged on both sides of the briquetting 24. The distance between the push plate 25 and the briquetting 24 is equal to the distance between the two molding cavities 23.

[0055] The front end face of the push plate is located at a depth of a molding cavity on the front side of the front end face of the pressing block. When any molding cavity moves to correspond to between the pressing block and the pressure plate, the other molding cavity can just correspond to the push plate on one side. As a preferred embodiment, the pressing block is moved and set in the feed pipe, and a feed port is opened on the tube wall of the feed pipe. The collected waste chips are added to the feed pipe through the feed port, and then the pressing block is driven by the cylinder to be pushed along the direction of the feed pipe to push the waste chips into the corresponding molding cavity, and the pressing block and the pressure plate work together to compact the waste chips into blocks. At the same time, the waste chip block formed in the other chamber is pushed out by the push plate, completing the molding and demolding of the waste chip block once. After the pressing block and the push rod are put together, the empty cavity is replaced to correspond to between the pressing block and the pressure plate, and the above action is repeated, so as to realize the alternating molding and demolding of the two chambers, thereby realizing the simultaneous molding and demolding of the waste chip block, and improving the efficiency of the waste chip pressing block processing.

[0056] The above description is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the above principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
