DETAILED DESCRIPTION

[0020] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0021] See also Figure 1-Figure 15 , the present invention provides a technical solution: Example: like Figure 1-Figure 15 As shown, a fire door core material cutting and dust blowing automatic line includes five cutting and dust blowing production lines, wherein the cutting and dust blowing production lines include a turning device 1, a fine cutting device 2, an intermediate workbench 3 and a dust blowing device 4 which are arranged in sequence; The flipping device 1 is used to flip the entire core material 48 90 degrees and then feed it into the fine cutting device 2; the flipping device 1 is used to switch the bottom surface of the core material 48, such as switching the original bottom surface where the length and width are located to the new bottom surface where the length and height are located.

[0022] The precision cutting device 2 is used to cut the whole core material 48 into a plurality of plates 59 of equal thickness; The intermediate workbench 3 is used to carry the separated sheets 59, and is manually fed one by one into the dust blowing device 4; The dust blowing device 4 is used to remove the debris and dust remaining on the plate material 59 .

[0023] Working principle: The whole core material 48 is fed into the turning device 1 , which turns the core material 48 90 degrees and then feeds it into the fine cutting device 2 .

[0024] The fine cutting device 2 simultaneously divides the whole core material 48 into multiple plates 59 of equal thickness. After the division is completed, the multiple plates 59 are sent to the dust blowing device 4 one by one. The dust blowing device 4 removes the debris and dust remaining on the surface of the plate 59 and then completes.

[0025] Wherein, multiple cutting and dust blowing production lines are provided to ensure that the core material 48 is evenly distributed on the multiple cutting and dust blowing production lines when being fed, and to ensure that there is a feeding gap between each cutting and dust blowing production line, so as to reserve time for subsequent sheets 59 to enter the dust blowing device 4 one by one, thereby ensuring the continuity of cutting and dust removal work.

[0026] The present invention realizes continuous cutting of the core material 48 and dust blowing by combining the turning device 1, the precision cutting device 2, the intermediate workbench 3 and the dust blowing device 4, thereby greatly improving the production efficiency.

[0027] Furthermore, if Figure 1 , Figure 2 and Figure 3 As shown, the turning device 1 comprises a bracket 6, on which a feeding area 7 and a discharging area 8 are provided, and a turning assembly is provided between the feeding area 7 and the discharging area 8; The feeding area 7 and the discharging area 8 are both provided with a plurality of moving rollers 9 for translating the core material 48; The turning assembly is used to drive the core material 48 in the feeding area 7 to turn 90 degrees and then enter the discharging area 8.

[0028] The flip assembly includes at least one set of flip arms 10, the flip arms 10 include a wide arm 11 and a high arm 12, the wide arm 11 and the high arm 12 are vertically arranged, the wide arm 11 and the high arm 12 are rotatably connected to the bracket 6 through a rotating shaft 13, and the flip arm 10 is driven to flip by a driving member; Before the core material 48 is flipped, the wide arm 11 is located between the moving rollers 9 of the feeding area 7, and the upper surface of the wide arm 11 is located below the bottom surface of the core material 48; after the core material 48 is flipped, the high arm 12 is located between the moving rollers 9 of the discharging area 8, and the upper surface of the high arm 12 is located below the bottom surface of the core material 48.

[0029] The wide arm 11 and the high arm 12 are connected by a horizontal arm 14, the rotating shaft 13 is coaxially arranged in the horizontal arm 14, and the two ends of the rotating shaft 13 are respectively located outside the two ends of the horizontal wall, and the two ends of the rotating shaft 13 are rotatably connected to the bracket 6 through a bearing seat and a bearing.

[0030] The driving member comprises a telescopic cylinder 15 , a cylinder end of the telescopic cylinder 15 is hinged to the bracket 6 , and a piston rod end of the telescopic cylinder 15 is hinged to an end of the wide arm 11 away from the high arm 12 .

[0031] The driving member comprises a telescopic cylinder 15 , a cylinder end of the telescopic cylinder 15 is hinged to the bracket 6 , and a piston rod end of the telescopic cylinder 15 is hinged to an end of the wide arm 11 away from the high arm 12 .

[0032] Among them, 1. Three groups of flip arms 10 are set in this embodiment; 2. Before the core material 48 enters the feeding area 7, the wide arm 11 is located between the moving rollers 9, and the wide arm 11 is in a horizontal state at this time; the high arm 12 is in a vertical state. 3. The moving rollers 9 are driven by chains, sprockets, and motors, and two adjacent moving rollers 9 are connected by chains and sprockets. The specific driving principle is the existing technology and will not be repeated here. The moving rollers 9 in the feeding area 7 and the discharging area 8 are driven by two motors respectively.

[0033] Working principle: After demoulding, the core material 48 is sent to the feeding end of the feeding area 7 of the bracket 6 by a conveying device (which may be but is not limited to a conveyor belt). When part (front end) of the core material 48 enters the feeding area 7, the moving roller 9 in the feeding area 7 drives the core material 48 to move along the feeding area 7 until the core material 48 completely enters the feeding area 7. When the core material 48 is fed, ensure that the bottom surface and side surface of the core material 48 are respectively in contact with the top surface of the wide arm 11 and the side surface of the high arm 12.

[0034] After the core material 48 completely enters the feeding area 7, the piston rod of the telescopic cylinder 15 extends to drive the flip arm 10 to flip. During the flipping process, the piston rod applies an upward force to the end of the wide arm 11, and then drives the flip arm 10 to rotate along the rotation axis 13 through the wide arm 11.

[0035] After the flipping is completed, the high arm 12 is located between the moving rollers 9 of the discharge area 8, and the high arm 12 is in a horizontal state, and the wide arm 11 is in a vertical state. The flipped core material 48 is sent to the next cutting and sheeting station through the moving rollers 9 provided in the discharge area 8 to start cutting the core material 48.

[0036] By providing the turning arm 10 , the core material 48 can be turned over 90 degrees automatically, and during the turning process, the core material 48 is supported by the wide arm 11 and the high arm 12 , thereby ensuring the stability of the turning of the core material 48 .

[0037] Furthermore, the bracket 6 is provided with a first sensor 16 and a second sensor 17, wherein the first sensor 16 is arranged in the feeding area 7 for detecting the position of the wide arm 11; and the second sensor 17 is arranged in the discharging area 8 for detecting the position of the high arm 12. The first sensor 16 and the second sensor 17 may be, but are not limited to, proximity switches.

[0038] When the wide arm 11 is horizontal, the first sensor 16 can detect the position of the wide arm 11, which indicates that the core material 48 has not been flipped; when the high arm 12 is horizontal, the second sensor 17 can detect the position of the high arm 12, which indicates that the flipping of the core material 48 has been completed.

[0039] Furthermore, positioning baffles 18 are respectively provided on both sides of the bracket 6 , and the positioning baffles 18 are arranged perpendicular to the moving roller 9 .

[0040] Both ends of the positioning baffle 18 are folded outward to form inclined guide edges 57 .

[0041] The baffle and guide edge 57 are used for guiding and limiting the core material 48 when the moving roller 9 drives the core material 48 to move horizontally, ensuring that the axis of the core material 48 is perpendicular to the axis of the moving roller 9 to avoid the core material 48 from deviating.

[0042] Furthermore, if Figure 1 , Figure 4-Figure 7 As shown, the precision cutting device 2 includes a precision cutting feeding conveyor belt 19, a precision cutting transition conveyor belt 20, a precision cutting discharging conveyor belt 21 and a precision cutting frame 22; The precision cutting transition conveyor belt 20 passes through the precision cutting frame 22, and the precision cutting feed conveyor and precision cutting conveyor belt are respectively arranged at both ends of the precision cutting transition conveyor belt 20; The precision cutting frame 22 is provided with a precision cutting saw frame 23 , and the precision cutting saw frame 23 is provided with a plurality of vertical saw blades 24 , and the plurality of saw blades 24 are distributed at equal intervals.

[0044] Working principle: The whole piece of core material 48 is fed from the fine cutting feed conveyor belt 19 to the fine cutting transition conveyor belt 20 located in the fine cutting frame 22.

[0045] The fine-cut transition conveyor belt 20 continues to convey the whole core material 48 toward the fine-cut saw frame 23. When the core material 48 contacts the saw blade 24, the core material 48 is cut into multiple pieces by the saw blade 24. The cut core material 48 (hereinafter referred to as the material plate) is sent out by the fine-cut discharge conveyor belt 21.

[0049] When in use, the precision cutting motor 27 drives the dynamic precision cutting drive wheel 28 to move, and the precision cutting drive wheel 28 drives the precision cutting driven wheel 29 to move through the belt. When the precision cutting driven wheel 29 moves, the precision cutting transmission shaft 30 rotates synchronously, and the rotation of the precision cutting transmission shaft 30 drives the precision cutting transmission wheel 31 to move. When the precision cutting transmission wheel 31 moves, it drives the precision cutting saw frame 23 to reciprocate up and down through the driving plate 32.

[0050] Furthermore, a U-shaped frame 33 is provided on the fine-cutting frame 22 , and the fine-cutting saw frame 23 is connected to the U-shaped frame 33 via a tension spring 34 .

[0051] Among them, 1. The two ends of the tension spring 34 are respectively connected to the U-shaped frame 33 and the top of the fine-cutting saw frame 23 (the top of the fine-cutting saw frame 23 is provided with a nut with a horizontal axis). 2. Four tension springs 34 are respectively provided on both sides of the fine-cutting saw frame 23 located on the driving plate 32.

[0054] The connection method of the second connection portion is the same as that of the first connection portion 43, which will not be described in detail here.

[0055] Furthermore, the precision cutting saw frame 23 is provided with at least one set of clamping components on both sides along the running direction of the precision cutting transition conveyor belt 20; The clamping assembly is used to limit the vertical displacement of the core material 48 .

The lowest point of the pressing roller 35 is flush with the top surface of the core material 48 or slightly lower than the top surface of the core material 48 by 1mm-5mm.

[0058] When in use, before the core material 48 is cut, its end first lifts the pressing roller 35 in front of the saw blade 24, and the pressing roller 35 applies pressure to the core material 48 through the first spring 38. When the core material 48 is cut, its front end is pressed by the pressing roller 35 behind the saw blade 24 through the saw blade 24; the two sets of pressing rollers 35 cooperate to limit the axial position of the core material 48, thereby preventing the core material 48 from jumping vertically due to friction or other resistance between the saw blade 24 and the core material 48 during cutting, and also preventing problems such as neat cutting surface and material jamming caused by vertical jumping.

[0061] Furthermore, the precision-cutting discharging conveyor belt 21 is provided with limit baffles 41 on both sides along its running direction, and the distance between the two limit baffles 41 is adapted to the thickness of the core material 48 before cutting.

[0064] Furthermore, if Figure 1 , Figure 8-Figure 10 The dust blowing device 4 shown in the figure comprises a dust blowing conveying frame 49, the two ends of the dust blowing conveying frame 49 are respectively a feeding end and a discharging end, and a dust removal cover 50 is provided in the middle of the dust blowing conveying frame 49; The dust blowing conveying frame 49 is provided with two limit frames 51 along its running direction, and a dust blowing gap (such as Fig.10 As shown by X in the figure), the limit frame 51 is provided with a wind knife 52 for blowing dust; One of the limit frames 51 is connected to the dust cover 50 through an adjusting member, and the adjusting member is used to drive the adjusting member to move along the width direction of the dust blowing conveying frame 49 to adjust the dust blowing gap.

[0065] 1. The dust blowing conveyor frame 49 is a plate chain conveyor. 2. Both of the two limit frames 51 can be set to be movable. In this embodiment, one of the limit frames 51 is set to be movable and the other limit frame 51 is set to be fixed. In this setting, only one limit frame 51 needs to be adjusted, which is convenient for adjusting the dust blowing gap.

[0066] Working principle: The cut plate-shaped core material 48 (hereinafter referred to as plate material 59) is placed vertically and sent into the dust removal cover 50 from the feeding end of the dust blowing conveyor 49. The plate material 59 entering the dust removal cover 50 enters the dust blowing gap, and the wind knives 52 located on both sides of the plate material 59 blow the two sides of the plate material 59 respectively, thereby blowing off the dust on the plate material 59. After the dust blowing is completed, the clean plate material 59 is sent out from the discharging end of the dust blowing conveyor 49.

[0067] When it is necessary to blow dust off the sheets 59 of different thicknesses, one of the limit frames 51 is driven to approach / move away from the other limit frame 51 through the adjusting member, thereby reducing / enlarging the dust blowing gap.

[0068] By setting the adjusting member, the distance between the two limit frames 51 can be adjusted, and then the size of the dust blowing gap can be adjusted to meet the dust blowing requirements of plates with different thicknesses, thereby improving the application range of the dust removal equipment.

[0069] Furthermore, the dust cover 50 is a rectangular shell structure, and an inlet and an outlet are respectively provided at both ends of the dust cover 50; Two adjusting members are respectively arranged at both ends of the limiting frame 51 , and the adjusting members include an adjusting screw 53 , and the adjusting screw 53 is threadedly connected to the dust cover 50 , and a first end of the adjusting screw 53 passes through the dust cover 50 and is rotatably connected to the limiting frame 51 .

[0070] A hand wheel 54 is disposed at the second end of the adjusting screw rod 53 .

[0071] The dust blowing and conveying frame 49 is provided with a first support rail 55 , and the bottom of the limiting frame 51 is provided with a second support rail 56 corresponding to the first support rail 55 above and below, and the second support rail 56 is movably arranged on the first support rail 55 .

[0072] Among them, 1. The second support rail 56 is directly placed on the first support rail 55, and there is no rigid connection between the two. 2. The threaded connection method is: the adjusting screw 53 is threadedly connected to the dust cover 50 through a nut, and the nut is fixed to the dust cover 50. 3. The end of the adjusting screw 53 is rotatably connected to the limit frame 51 through a bearing, a bearing seat, and a vertical rod. 4. The first support rail 55 and the second support rail 56 are both made of rectangular steel.

[0073] The first support rail 55 and the second support rail 56 are used to support the limiting frame 51 to lift the limiting frame 51 to prevent the bottom of the limiting frame 51 from sitting on the dust blowing and conveying frame 49 and generating friction with the dust blowing and conveying frame 49 .

[0074] Furthermore, the ends of the two limiting frames 51 are both folded outward to form guide edges 57. The provided guide edges 57 are used to guide the sheet when entering, so as to avoid collision between the ends of the sheet and the limiting frames 51.

[0075] Furthermore, a plurality of guide rollers are evenly distributed on the limiting frame 51 , and the guide rollers are axially vertically arranged.

[0076] The guide roller is used to limit the position of the sheet to prevent it from tipping over. At the same time, the guide roller is set to rotate, and there is rolling friction between it and the sheet, which can reduce the resistance of the sheet forward.

[0077] Furthermore, at least one dust suction port 58 is provided on the top of the dust removal cover 50, and the dust suction port 58 is connected to a dust suction device. The dust suction device is a prior art, which is used to suck away the dust blown off by the wind knife 52 to prevent dust from accumulating in the dust removal cover 50.

[0078] Furthermore, the ends of the two limiting frames 51 located at the feeding end of the dust blowing conveying frame 49 are arranged in a front-to-back staggered manner, so as to provide space for the feeding of the material sheet.

[0079] Furthermore, if Figure 1 , Figure 11-Figure 15 The figure also includes a lifting and transplanting device 5 arranged at the front end of the turning device 1 (the front end here refers to the front end of the feeding end of the turning device 1); The lifting and transplanting device 5 is used to drive the core material 48 to move in a direction parallel to the turning device 1 or to drive the core material 48 to move in a direction perpendicular to the turning device 1 .

[0080] The lifting and transplanting device 5 comprises a transplanting frame 60, on which a plurality of transplanting rollers 61 are evenly arranged, and between two adjacent transplanting rollers 61 there is a transplanting conveyor belt 62, wherein the axial direction of the transplanting roller 61 is parallel to the running direction of the transplanting conveyor belt 62; The transplanting roller 61 is driven by a first driving mechanism 63, and the transplanting conveyor belt 62 is driven by a second driving mechanism 64; The transplanting conveyor belt 62 is connected to the transplanting frame 60 through a lifting assembly, and the lifting assembly is used to drive the transplanting conveyor belt 62 and the second driving mechanism 64 to rise as a whole until the surface of the transplanting conveyor belt 62 is higher than the transplanting roller 61 or to descend until the surface of the transplanting conveyor belt 62 is lower than the transplanting roller 61.

[0081] The second driving mechanism 64 includes a driving shaft, a transmission shaft and a second driving motor. The first ends of the multiple transplanting conveyor belts 62 are connected to the transmission shaft, and the second ends of the multiple transplanting conveyor belts 62 are connected to the driving shaft. The driving shaft is connected to the second driving motor through a sprocket and a chain.

[0082] The first driving mechanism 63 includes a first driving motor, the output shaft of which is connected to one of the transplanting rollers 61 via a sprocket and a chain, and two adjacent transplanting rollers 61 are connected via a sprocket and a chain. The specific transmission method is prior art and will not be described in detail here.

[0083] Among them, 1. The transplanting conveyor belt 62 is a PVC guide strip conveyor belt.

[0084] Working principle: When the core material 48 is fed, it enters the transplanting rack 60 perpendicularly to the axis of the transplanting roller 61. After the core material 48 enters the transplanting rack 60, the first driving mechanism 63 drives the transplanting roller 61 to move. When the transplanting roller 61 moves, it drives the core material 48 to move, thereby ensuring that the core material 48 completely enters the transplanting rack 60.

[0085] At this time, if the feeding direction of the core material 48 needs to continue to move in a direction perpendicular to the axial direction of the transplanting roller 61 (entering the next transplanting rack 60 ), the transplanting roller 61 drives the core material 48 to continue to move until the core material 48 moves out of the transplanting rack 60 .

[0086] If the feeding direction of the core material 48 needs to be parallel to the axial direction of the transplanting roller 61 to enter the corresponding station of the transplanting frame 60, the transplanting roller 61 stops moving. The lifting assembly drives the transplanting conveyor belt 62 to rise until the transplanting conveyor belt 62 lifts the core material 48 until the bottom surface of the core material 48 is separated from the transplanting roller 61. At this time, the core material 48 is supported by the transplanting conveyor belt 62. The second driving mechanism 64 is started to drive the transplanting conveyor belt 62 to run. When the transplanting conveyor belt 62 runs, it drives the core material 48 to move in a direction parallel to the axial direction of the transplanting roller 61.

[0087] By integrating the transplanting roller 61 with a vertical moving direction and the transplanting conveyor belt 62 on the same transplanting frame 60, the core material 48 can be transported in two directions without occupying additional space, thereby improving space utilization while ensuring the efficiency of transporting the core material 48.

[0088] Further, the jacking assembly includes a jacking frame 65 and at least one jacking driving member 66, the jacking frame 65 includes a supporting transverse plate 67 and a third connecting portion 68, the third connecting portion 68 is connected to the side of the transplanting conveyor belt 62, and the bottom surface of the third connecting portion 68 is connected to the supporting transverse plate 67; The lifting driving member 66 is connected to the supporting transverse plate 67 and is used to drive the supporting transverse plate 67 to move vertically.

[0089] The lifting driving member 66 is a pneumatic cylinder or a hydraulic cylinder, and the piston rod of the lifting driving member 66 is vertically arranged and connected to the supporting cross plate 67 .

[0090] There are two lifting frames 65, which are respectively arranged at the head and tail ends of the transplanting conveyor belt 62; The supporting cross plate 67 of each lifting frame 65 is driven by two lifting driving members 66 respectively.

[0091] The lifting frame 65 is provided with two to ensure that the transplanting conveyor belt 62 can be smoothly raised or lowered. When the transplanting conveyor belt 62 needs to be raised, the cylinder or hydraulic cylinder is started, and the piston rod of the cylinder or hydraulic cylinder drives the transplanting conveyor belt 62 to rise through the supporting cross plate 67.

[0092] Furthermore, the transplanting rack 60 is rotatably connected with a first rotating shaft 69 and a second rotating shaft 70, and the first rotating shaft 69 and the second rotating shaft 70 respectively correspond to the two supporting transverse plates 67 up and down and are staggered. The staggered arrangement here means that the supporting transverse plate 67 and the first rotating shaft 69 do not overlap in the vertical projection, and the same is true for the supporting transverse plate 67 and the second rotating shaft 70.

[0093] An L-shaped first synchronous plate 71 is provided at both ends of the first rotating shaft 69, and an L-shaped second synchronous plate 72 is provided at both ends of the second rotating shaft 70; the first end of the first synchronous plate 71 is connected to the first end of the second synchronous plate 72 located on the same side through a connecting rod 73, and the second end of the first synchronous plate 71 and the second end of the second synchronous plate 72 are connected to the two supporting transverse plates 67 through a synchronous rod 74. The two ends of the connecting rod 73 are hinged to the first synchronous plate 71 and the second synchronous plate 72, respectively, and the two ends of the synchronous rod 74 are hinged to the first synchronous plate 71 / the second synchronous plate 72 and the rib plate arranged at the bottom of the supporting transverse plate 67.

[0094] The synchronous plate, connecting rod 73 and rotating shaft are used to ensure the synchronous lifting of both ends of the transplanting conveyor belt 62. When the lifting driving member 66 drives the supporting transverse plate 67 to rise, the supporting transverse plate 67 drives the first synchronous plate 71 / the second synchronous plate 72 to rotate, and when the first synchronous plate 71 / the second synchronous plate 72 rotates, the second synchronous plate 72 / the first synchronous plate 71 at the other end is driven to rotate, and when the second synchronous plate 72 / the first synchronous plate 71 at the other end rotates, the supporting transverse plate 67 at this end is lifted by the synchronous rod 74 at this end, thereby ensuring the synchronous lifting of the two supporting transverse plates 67.
