Description

Technical Field

[0002] Glass wool insulation board is a kind of decoration material with good molding, small volume density, low thermal conductivity and thermal insulation. When glass wool insulation board is produced, it is usually a long strip of board. Before use, it is usually necessary to cut the glass wool insulation board into small pieces of suitable size to facilitate the subsequent processing and sales of glass wool insulation board. However, glass wool is a kind of brittle material. Therefore, when cutting it, it is necessary to reduce the cutting speed as much as possible to avoid collision between glass wool insulation board and cutter, resulting in glass wool. The glass wool insulation board is shattered, but the thickness of the glass wool insulation board is inversely proportional to its brittleness, and the existing cutting device cannot automatically adjust the feed speed during cutting according to the thickness of the glass wool insulation board. When the thinner insulation board is cut at a cutting speed suitable for the thicker glass wool insulation board, the relative movement speed between the thinner glass wool insulation board and the cutting tool is prone to be too fast, and the thinner glass wool insulation board is more susceptible to excessive extrusion pressure, causing the thinner glass wool insulation board to crack at the cut, resulting in the quality of the thinner glass wool insulation board being unqualified after cutting.

DETAILED DESCRIPTION

[0034] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0035] Example 1: The existing device is unable to automatically adjust the feed speed when cutting the glass wool insulation board according to the thickness of the glass wool insulation board. When a thinner glass wool insulation board is cut at a higher speed, the thinner glass wool insulation board is subjected to a greater squeezing pressure from the tool, and the edge of the cut is prone to cracking. When a thicker glass wool insulation board is cut at a lower speed, the tool and the cutting portion of the thicker glass wool insulation board rub against each other for a long time, which can easily cause local overheating of the thicker glass wool insulation board, and will also affect the flatness of the cut of the thicker glass wool insulation board.

[0036] A glass wool insulation board cutting device with auxiliary positioning function, such as Figure 1-Figure 7As shown, the machine frame 1 includes a square frame 2, a first tool holder 3, a second tool holder 4 and a material unloading frame 5 fixedly connected to the upper side of the machine frame 1. The first tool holder 3 is arranged at the left part of the rear side of the machine frame 1. The first tool holder 3 cuts the material longitudinally by the electric saw 12 thereon. The second tool holder 4 is arranged at the front side of the machine frame 1. The second tool holder 4 cuts the material transversely by the electric saw 12 thereon. The material unloading frame 5 is located at the front side of the second tool holder 4. The material unloading frame 5 is provided with a transmission roller for receiving the finished material. The machine frame 1 is provided with a second roller transmission frame 6 and a first roller transmission frame 61 (the number of the second roller transmission frame 6 and the first roller transmission frame 61 can be freely adjusted according to the working conditions). and installation length), the second roller transmission frame 6 and the first roller transmission frame 61 are both electrically connected to the remote control device, the second roller transmission frame 6 corresponds to the second knife frame 4, and is used to cut the material horizontally, the first roller transmission frame 61 corresponds to the first knife frame 3, and is used to cut the material longitudinally, the second roller transmission frame 6 and the first roller transmission frame 61 are both provided with a plurality of transmission rollers 7, and the adjacent two transmission rollers 7 are mutually transmitted through a sprocket chain, and are used to drive the material to move along the adjacent second roller transmission frame 6 or the adjacent first roller transmission frame 61, and the second roller transmission frame 6 and the first roller transmission frame 61 are both rotatably connected with a speed change roller 8, which is used to adjust the movement of the material. The speed of the variable-speed roller 8 is spline-connected with a conical wheel 9. The conical wheel 9 on the second roller transmission frame 6 and the adjacent transmission roller 7 are driven by a pulley belt. The conical wheel 9 on the first roller transmission frame 61 and the right and adjacent transmission roller 7 are driven by a pulley belt. The maximum diameter of the conical wheel 9 is smaller than the diameter of the pulley on the adjacent transmission roller 7. Therefore, the rotation speed of the conical wheel 9 is always greater than the rotation speed of the adjacent transmission roller 7, which is used to make two adjacent materials separate by themselves due to the speed difference, so that the subsequent mechanism can process a single material more accurately. The first tool holder 3 and the second tool holder 4 are both provided with an electric slide rail electrically connected to the remote control device. The electric slide rail of the first tool holder 3 and the second tool holder The electric slide rails 4 are slidably connected with a plurality of electric sliders 10 for adjusting the positions of adjacent electric saws 12 to cooperate with the working state of the electric saws 12 and cut the materials in different sizes. A hydraulic push rod 11 is fixedly connected to the upper side of the electric slider 10. The telescopic end of the hydraulic push rod 11 is installed with the electric saw 12 electrically connected to the remote control device. The second roller transmission frame 6 and the first roller transmission frame 61 are jointly provided with a detection mechanism for detecting the diameter of the material. The second roller transmission frame 6 and the first roller transmission frame 61 are jointly provided with a speed change mechanism for adjusting the transmission ratio between the two conical wheels 9 and the adjacent transmission rollers 7. The speed change mechanisms are electrically connected to the remote control device.

[0037] like Figure 1-Figure 4 and Figure 6As shown, the detection mechanism includes a final conveying frame 13 arranged on the front side of the second roller transmission frame 6, and the final conveying frame 13 is provided with a plurality of final conveying rollers 131 for conveying the material to the lower material frame 5. The speed change roller 8 at the second roller transmission frame 6 and the adjacent final conveying roller 131 are driven by a sprocket chain, so the rotation speed of the final conveying roller 131 is consistent with the rotation speed of the adjacent speed change roller 8, which is used to adjust the feeding speed during material cutting. The speed change roller 8 at the first roller transmission frame 61 and the right and adjacent transmission roller 7 are driven by a sprocket chain, so the rotation speed of the right transmission roller 7 of the first roller transmission frame 61 is the same as the rotation speed of the adjacent speed change roller 8, which is used to adjust the feeding speed during material cutting. The front side of the second roller transmission frame 6 and the right side of the first roller transmission frame 61 are fixedly connected with symmetrically distributed n-shaped frames 14, and a sliding plate 15 and a sliding block 16 are slidably connected in the n-shaped frame 14. The n-shaped frame 14 is threadedly connected with a threaded handle 18, and the threaded handle 18 It is rotatably connected to the adjacent sliding plate 15 and is used to manually adjust the position of the sliding plate 15, thereby preliminarily adjusting the pressure of the first elastic member 17. A first elastic member 17 is fixedly connected between the sliding plate 15 and the adjacent sliding block 16. The first elastic member 17 is a spring. The two symmetrically distributed sliding blocks 16 are spline-connected with an extrusion roller 161. The extrusion roller 161 and the adjacent final conveying roller 131 or the adjacent transmission roller 7 jointly clamp the material, thereby controlling the material to move toward the adjacent electric saw 12 at a more stable speed. The second roller transmission frame 6 is slidably connected to two symmetrically distributed positioning frames 25 through a bracket, and a third elastic member 26 is fixedly connected between the two. The third elastic member 26 is a tension spring. The final conveying roller 131 on the rear side is spline-connected to the final conveying frame 13. The rear side surfaces of the two positioning frames 25 are both provided with inclined surfaces. The two positioning frames 25 extrude the material through the inclined surfaces, and provide the material with a force to keep it centered through the two third elastic members 26.

[0038] like Figure 3-Figure 5 and Figure 7As shown, the speed change mechanism includes two first hydraulic telescopic rods 19, which are respectively fixed to the front side of the second roller transmission frame 6 and the right side of the first roller transmission frame 61, and the telescopic end of the first hydraulic telescopic rod 19 is fixed to the adjacent sliding block 16, which is used to detect the thickness of the material by the position of the squeezing roller 161. The second roller transmission frame 6 and the first roller transmission frame 61 are both fixed with a fixed frame 20, and the fixed frame 20 is fixed with a second hydraulic telescopic rod 21. The first hydraulic telescopic rod 19 is connected to the adjacent second hydraulic telescopic rod 21 through a hose, and the telescopic end of the second hydraulic telescopic rod 21 is fixed to the adjacent conical wheel 9, which is used to push the adjacent conical wheel 9 to move, thereby changing the conical wheel 9 and the corresponding The transmission ratio between the pulleys of adjacent transmission rollers 7 is changed, thereby changing the rotation speed of the adjacent speed-changing rollers 8. The fixed frame 20 is slidably connected to three circumferentially distributed blocking blocks 22 through a bracket. A second elastic member 23 is fixed between the blocking block 22 and the adjacent fixed frame 20. The second elastic member 23 is a spring, which is used to push the blocking block 22 to always keep in contact with the adjacent conical wheel 9 to prevent the adjacent belts from sliding on the adjacent conical wheel 9, thereby increasing the accuracy of transmission ratio adjustment. The blocking block 22 and the fixed frame 20 are both squeezed and matched with the adjacent belts. The front side of the second roller transmission frame 6 and the right side of the first roller transmission frame 61 are both installed with a tensioning wheel 24. The tensioning wheel 24 is squeezed and matched with the adjacent belts to keep the belts in a taut state at all times.

[0039] When the staff is cutting the glass wool insulation board (material), they first start the first roller transmission frame 61 and the second roller transmission frame 6 through the remote control device, and then control the hydraulic push rod 11 that needs to work through the remote control device to drive the adjacent parts to extend downward (for example, if the material needs to be cut longitudinally into four parts, it is only necessary to control the three hydraulic push rods 11 on the first tool holder 3 to drive the adjacent electric saw 12 to move downward, so that the electric saw 12 on it cuts the moving material), and then the staff controls the electric slide rails on the first tool holder 3 and the second tool holder 4, and controls the electric slide block 10 at the electric saw 12 that needs to work to move to the indicated position. The electric saw 12 is moved to a fixed position (for example, if the material needs to be cut into four equal parts longitudinally, the electric sliders 10 on all the first tool holders 3 are controlled to move so that the distances between the two adjacent electric saws 12 in the working state are equal to each other). After adjusting the position of the electric saw 12, the staff adjusts the position of the adjacent sliding blocks 16 through the threaded handle 18 so that the squeezing roller 161 and the first elastic member 17 can apply a suitable clamping force to the material to ensure that the material is transported smoothly while avoiding excessive clamping force that may damage the material. Then the staff starts the electric saw 12, places the material on the first roller transmission frame 61, and cuts the material.

[0040] When the material is placed on the first roller transmission frame 61, the first roller transmission frame 61 transports the material on it to the right. When the material passes through the squeezing roller 161 and other components on the first roller transmission frame 61, the material is squeezed by the squeezing roller 161 and the adjacent transmission roller 7, and is clamped by the two and continues to move toward the first tool holder 3. When the material contacts the electric saw 12 on the first tool holder 3, it is cut by the working electric saw 12. The cut material is driven by the first roller transmission frame 61 to the right to the top of the second roller transmission frame 6, and then the material is driven by the second roller transmission frame 6 to move forward. After the material passes through the electric saw 12 at the second tool holder 4 in the same steps as on the first roller transmission frame 61, it is cut into materials of appropriate specifications. Then the material is transmitted to the unloading rack 5 by the last conveying roller 131 on the second roller transmission frame 6. The staff collects qualified materials on the unloading rack 5 and continues to cut the next material.

[0041] When the material passes through the squeezing roller 161, the squeezing roller 161 will not only squeeze the material to ensure that the material is more stably transmitted to the adjacent electric saw 12, but the squeezing roller 161 will also change the rotation speed of the adjacent variable speed roller 8 according to the thickness of the material, thereby changing the relative movement speed between the material and the adjacent electric saw 12. The specific principle is as follows (the squeezing roller 161 and adjacent components at the second roller transmission frame 6 are used as an example for explanation. The working principle of the squeezing roller 161 at the first roller transmission frame 61 is the same as that of the squeezing roller 161 at the second roller transmission frame 6. Because the material at the first roller transmission frame 61 is a whole piece of insulation board, the speed change of the variable speed roller 8 has no effect on the lateral movement speed of the material, and the speed of the squeezing roller 161 and the adjacent transmission roller 7 squeezing the material movement is the final material movement speed):

[0042] When the material passes through the squeezing roller 161 at the second roller transmission frame 6, the material is squeezed into between the squeezing roller 161 and the adjacent last-position conveying roller 131 under the rolling action of the squeezing roller 161 and the adjacent last-position conveying roller 131. The squeezing roller 161 is squeezed by the material to drive the adjacent sliding block 16 and other parts to move upward, the adjacent first elastic member 17 is compressed and stored, and the sliding block 16 synchronously drives the telescopic end of the first hydraulic telescopic rod 19 to move upward, the first hydraulic telescopic rod 19 extracts the hydraulic oil in the adjacent second hydraulic telescopic rod 21 through the hose, and the telescopic end of the second hydraulic telescopic rod 21 drives the conical wheel 9 to retract to the left, and the movement of the conical wheel 9 increases the transmission ratio between the pulley on the adjacent transmission roller 7 and the conical wheel 9, and the rotation speed of the conical wheel 9 increases, and the conical wheel 9 drives the speed change roller 8 through the spline By appropriately increasing the rotation speed, the speed-changing roller 8 controls the increase of the rotation speed of the adjacent last conveying roller 131 through the sprocket chain (at the first roller transmission frame 61, the speed-changing roller 8 controls the increase of the rotation speed of the right and adjacent transmission roller 7 through the sprocket chain). At this time, the rotation speed between the last conveying roller 131 and the squeezing roller 161 increases, thereby increasing the relative movement speed between the material and the electric saw 12, and the increase increases with the thickness of the material, thereby distinguishing the cutting speed between materials of different thicknesses, making the cutting speed of thicker materials faster (this cutting speed is the normal cutting speed for thicker materials) to ensure cutting efficiency, and the cutting speed of thinner materials is slower to avoid the situation where the movement speed between the material and the electric saw 12 is too fast, resulting in excessive force on the material and cracking.

[0043] When the material passes through the squeezing roller 161 at the second roller transmission frame 6, the side of the material contacts the left or right positioning frame 25, and the positioning frame 25 in contact with the material squeezes the material through the adjacent third elastic member 26 and its own inclined surface, so that the material moves toward the center. When the other side of the material contacts the other positioning frame 25, the material is aligned in the center, so as to ensure the uniformity of the cutting of the material. When the material moves to the left and right sides during the centering process, the material drives the squeezing roller 161 and the adjacent last-position conveying roller 131 to move along their respective spline grooves, so that the squeezing force of the squeezing roller 161 and the adjacent last-position conveying roller 131 on the material will not hinder the squeezing of the material by the two positioning frames 25, thereby ensuring that the material can be easily moved to the center position. When the material is centered, the material squeezes the two positioning frames 25 away from each other on the front and rear sides, and the two third elastic members 26 compress and accumulate force. When the material is out of contact with the two positioning frames 25, the two positioning frames 25 are moved and reset under the action of the elastic force of the adjacent third elastic members 26.

[0044] When the staff has finished cutting all the materials, the staff turns off the electric saw 12, the first roller transmission frame 61 and the second roller transmission frame 6 through the remote control device, and controls the electric slide block 10 to drive the adjacent parts to reset.

[0045] Embodiment 2: Because some glass wool insulation boards do not go through the scrap process after production, and the scraps of these glass wool insulation boards usually need to be removed simultaneously when they are cut, and the existing device cannot automatically remove the cut scraps. The scraps produced by longitudinal cutting will be smaller and more complexly distributed after transverse cutting, which makes the work of the staff in collecting the scraps more cumbersome and complicated.

[0046] like Figure 8-Figure 12 As shown, it also includes a scrapping mechanism arranged on the upper side of the square frame 2, the scrapping mechanism is used to automatically remove the cutting scraps produced by longitudinal cutting, the scrapping mechanism includes an electric shaft 30 electrically connected to the remote control device, the electric shaft 30 is rotatably connected to the upper side of the square frame 2, the upper side of the square frame 2 is fixedly connected with two first electric telescopic rods 31 symmetrically distributed front and back, the first electric telescopic rods 31 are electrically connected to the remote control device, the telescopic end of the first electric telescopic rod 31 is fixedly connected with a moving frame 32, the left side of the moving frame 32 is provided with an inclined surface, which is used to completely squeeze the material scraps to the upper side of the adjacent guide plate 33, the moving frame 32 is slidably connected to the electric shaft 30, the back sides of the two moving frames 32 are fixedly connected with guide plates 33, the moving frame 32 is in contact with the second roller transmission frame 6, and the uppermost side of the second roller transmission frame 6 is lower than the height of the uppermost side of the transmission roller 7 on the first roller transmission frame 61, which is used to ensure that the material is When the first roller transmission frame 61 is transmitted to the second roller transmission frame 6, the cut scraps of the material are accurately intercepted by the guide plate 33. A number of miniature transmission rollers 34 are rotatably connected to the mobile frame 32 to provide power for the scraps of the material to prevent the scraps of the material from sliding down. The miniature transmission rollers 34 on the same mobile frame 32 are mutually transmitted through the sprocket chain. The miniature transmission rollers 34 and the guide plate 33 are rotatably matched. The end of the guide plate 33 is fixedly connected with an indicator rod 36. The indicator rod 36 is slidably connected to the first roller transmission frame 61. The length of the indicator rod 36 is greater than the length of the first roller transmission frame 61, which is convenient for the staff to place the material in the corresponding position by observing the positions of the two indicator rods 36. The lower side of the square frame 2 is rotatably connected to a rotating wheel 35 through a bracket. The rotating wheel 35 is connected to the adjacent miniature transmission roller 34 through a spline shaft, and the rotating wheel 35 and the electric shaft 30 are driven by a pulley belt.

[0047] When the staff adjusts the position of the electric saw 12 on the first tool holder 3 and the second tool holder 4, an additional set of working electric saws 12 is added on both sides to cut off the corners of the material to ensure the neatness of the edge of the material after cutting. The staff controls the electric shaft 30 to rotate through the remote control device. The electric shaft 30 drives the two rotating wheels 35 to rotate through the pulley and the belt. The rotating wheel 35 drives the adjacent micro-transmission roller 34 to rotate through the spline shaft to provide power for the scrap to move to the right. The staff simultaneously controls the telescopic ends of the two first electric telescopic rods 31 to drive the adjacent parts to extend. Taking the first electric telescopic rod 31 on the front side as an example: the telescopic end of the first electric telescopic rod 31 drives the moving frame 32, the guide plate 33, the indicator rod 36 and the micro-transmission roller 34 and other parts to extend backwards. This adjusts the contact position of the guide plate 33 and the second roller transmission frame 6 to ensure that the guide plate 33 contacts the scraps of the material. When the material moves to the right through the first roller transmission frame 61 and is cut, the scraps of the material first contact the moving frame 32 when passing through the first roller transmission frame 61 to move to the second roller transmission frame 6. Then, the scraps are gradually moved to the upper side of the guide plate 33 under the drive of the adjacent transmission roller 7. During the upward movement, the scraps are squeezed by the moving frame 32 and completely moved to the upper side of the guide plate 33. When the scraps are out of contact with the adjacent transmission roller 7, the scraps continue to move to the right under the drive of the micro-transmission roller 34 until the scraps are moved out of the position of the second roller transmission frame 6. The staff collects the scraps of the material through the existing collection device.

[0048] When the staff adjusts the position of the movable frame 32, the movable frame 32 synchronously drives the adjacent indicator rod 36 to move. The staff uses the indicator rod 36 as a reference to observe the relative position between the guide plate 33 and the electric saw 12, so that the staff can more conveniently control the movement of the telescopic end of the first electric telescopic rod 31. At the same time, when the staff places materials on the first roller transmission frame 61, the staff can place the materials at the specified position on the first roller transmission frame 61 more accurately according to the position of the indicator rod 36, avoiding the situation where the material is skewed and the cutting size is inaccurate.

[0049] When the material is cut by the adjacent electric saw 12 at the second roller transmission frame 6, the scraps of the material are concentrated on the left and right sides, which is convenient for the staff to collect them uniformly.

[0050] In Examples 1 and 2, the final conveyor frame 13 is considered to be fixedly connected to the second roller transmission frame 6, but in Example 3, the rear side of the final conveyor frame 13 is rotatably connected to the second roller transmission frame 6, and in Example 3, a transmission roller is also provided on the lower side of the unloading frame 5, and the transmission roller on the upper side of the unloading frame 5 is used to receive the finished material, and the transmission roller on the lower side of the unloading frame 5 is used to receive the unqualified material.

[0051] Embodiment 3: When the electric saw 12 is worn or the material quality is poor and cracks, resulting in uneven longitudinal cuts of the material, directly cutting the material horizontally may cause the material to be unqualified as a whole and cause the material to be scrapped as a whole. However, if the material is not cut at this time and the staff is waiting to collect the material and cut it manually, the utilization value of the material can be increased. However, the existing device does not have the function of judging the unevenness of the material cut, nor does it have the function of conveying the two materials separately.

[0052] like Figure 13-Figure 15 As shown, it also includes a discharge mechanism arranged on the lower side of the second tool holder 4, the discharge mechanism is used to discharge waste in time, the discharge mechanism includes a second electric push rod 40 fixedly connected to the left side of the lower part of the second tool holder 4, the rear side of the final conveying frame 13 is rotatably connected to the front side of the second roller transmission frame 6, the second electric push rod 40 is electrically connected to the remote control device, the telescopic end of the second electric push rod 40 is slidably and rotatably connected to the front side of the left part of the final conveying frame 13, used to drive the final conveying frame 13 to rotate, and a third hydraulic telescopic rod 41 is fixedly connected to the right side of the lower part of the second tool holder 4, which is used to synchronously increase the rotation speed of the speed change roller 8 when the final conveying frame 13 swings downward, so as to control the material to leave the final conveying frame 13 at a faster speed, and the third The telescopic end of the hydraulic telescopic rod 41 is slidably and rotatably connected to the front side of the last conveying rack 13. The third hydraulic telescopic rod 41 is connected to the second hydraulic telescopic rod 21 through a hose, and a pressure valve is provided at the connection point. Therefore, only when the last conveying rack 13 swings and causes a large pressure difference on both sides of the hydraulic oil, the third hydraulic telescopic rod 41 will be connected to the second hydraulic telescopic rod 21, and will not affect the transmission state between the second hydraulic telescopic rod 21 and the first hydraulic telescopic rod 19. The rear side of the last conveying rack 13 is fixedly connected to an electric sliding rack 42 electrically connected to the remote control device. The electric sliding rack 42 is slidably connected to a blocking plate 43. The blocking plate 43 is equipped with evenly distributed micro-touch switches for detecting the integrity of the longitudinal incision of the material.

[0053] When the material moves to the squeezing roller 161 position at the second roller transmission frame 6, the material is first blocked by the blocking plate 43 when passing through the squeezing roller 161 and the adjacent last-position conveying roller 131. At this time, the material cannot move forward following the rotation of the squeezing roller 161, and the material squeezes the micro-touch switches evenly distributed on the blocking plate 43. If the material rotates and deviates when moving from the first roller transmission frame 61 to the second roller transmission frame 6, the cut of the material is not perpendicular to the cutting direction of the electric saw 12 on the second tool holder 4. Therefore, only one end of the material contacts the micro-touch switch on the blocking plate 43 at this time, and the blocking plate 43 does not open. Driven by the squeezing roller 161, the material is not in contact with the blocking plate 43. The contact point continues to move forward until the other end of the material contacts the blocking plate 43. At this time, if the end surface of the material is cut flat by the electric saw 12 on the first tool holder 3, all the micro-touch switches on the blocking plate 43 that contact the material are triggered, and the triggered micro-touch switches form a complete straight line. The remote control device recognizes the continuous triggering signal of the micro-touch switches on the blocking plate 43, controls the electric sliding frame 42 to drive the blocking plate 43 to move, and the electric sliding frame 42 drives the blocking plate 43 to move downward. The blocking plate 43 no longer hinders the material from moving forward, and the material continues to move forward to be cut by the electric saw 12 at the second tool holder 4. At this time, the longitudinal incision of the material is perpendicular to its transverse incision, thereby ensuring the accuracy of the material cutting size.

[0054] When the cut of the material is not smooth, although the other end of the material directly contacts the micro-touch switch on the blocking plate 43, the triggered micro-touch switches on the blocking plate 43 cannot form a complete straight line, and there is a gap formed by the untriggered micro-touch switches, indicating that when the material is cut by the electric saw 12 on the first knife holder 3, the cut end surface of the material is not smooth due to the wear of the electric saw 12 or the cracking of the material. After receiving the signal from the micro-touch switch on the blocking plate 43, the remote control device controls the second electric push rod 40 to drive the contact point with the last conveyor rack 13 to move downward, and the last conveyor rack 13 is moved downward. 3 is swung downward along the rotation axis at the connection between it and the second roller transmission frame 6, and the remote control device simultaneously controls the electric sliding frame 42 to drive the blocking plate 43 to move downward and shrink, so that the material is no longer blocked by the blocking plate 43, and moves along the last conveying roller 131 on the last conveying frame 13 to the lower side of the lower material frame 5, and the lower part of the lower material frame 5 collects the unevenly cut materials, waiting for the staff to process the materials separately. At this time, the unqualified materials will not be cut by the electric saw 12 at the second roller transmission frame 6, so as to avoid cutting the unqualified materials, which will increase the difficulty of reusing the unqualified materials.

[0055] When the last conveying rack 13 swings downward, the telescopic end of the third hydraulic telescopic rod 41 is squeezed and retracted downward, and the third hydraulic telescopic rod 41 extracts the hydraulic oil in the adjacent second hydraulic telescopic rod 21. The telescopic end of the second hydraulic telescopic rod 21 drives the conical wheel 9 to retract and reset to the right, changing the transmission ratio between the conical wheel 9 and the adjacent transmission roller 7, increasing the rotation speed of the speed change roller 8, and the speed change roller 8 synchronously increases the rotation speed of the last conveying roller 131 to control unqualified materials to leave the last conveying rack 13 at a faster speed. After the unqualified materials leave the last conveying rack 13, the remote control device drives the adjacent parts to reset by controlling the second electric push rod 40, and the squeezing roller 161 and the adjacent parts continue to transport the subsequent materials. At this time, the third hydraulic telescopic rod 41 presses the hydraulic oil therein back into the adjacent second hydraulic telescopic rod 21, so that the adjacent speed change roller 8 resumes the rotation speed.

[0056] When materials are continuously transported to the lower part of the lower material rack 5 , the remote control device stops cutting the materials and promptly notifies the staff to check the electric saw 12 on the first knife rack 3 .
