Please refer to fig. 1 to 15.
The die cutting equipment provided by the invention has a structure shown in figure 1 and comprises a feeding table 1, a die cutting seat 3 and a deviation correcting conveying device 2. The feeding table 1 takes out the sheet materials 4 sheet by sheet from the sheet material pile, the deviation correcting conveying device 2 is positioned between the feeding table 1 and the die cutting seat 3 and is used for conveying the sheet materials 4 taken out of the feeding table 1 to the die cutting seat 3, and the die cutting seat 3 cuts the sheet materials 4. The deviation correcting conveying device 2 comprises a conveying table 21, a conveying belt 22 and a deviation correcting baffle 25. The conveyor belt 22 is located inside the conveying table 21 and above the upper surface of the conveying table 21. The conveyor belt 22 can thus contact the web 4 and transport it to the die-cutting station 3. A deviation rectifying baffle plate 25 is arranged on one side of the conveying table 21, and the distance between the conveying belt 22 and the deviation rectifying baffle plate 25 is gradually reduced along the direction approaching to the die cutting seat 3.
As shown in fig. 4, the sheet material 4 is driven by the conveyor belt 22 to move, and the distance between the sheet material and the deviation correcting baffle 25 is gradually reduced, and finally the sheet material is attached to the deviation correcting baffle 25. The sheet material 4 moves along the deviation correcting baffle 25, so that the sheet material is ensured not to incline when entering the die cutting seat 3.
Optionally, the deviation correcting conveying device 2 further comprises a pressing plate 23 located above the conveying table 21, and the pressing plate 23 is provided with a material pressing part. The sheet material 4 passes under the pressing plate 23, and the pressing part applies downward pressure to the sheet material 4 to enable the sheet material 4 to be tightly attached to the conveyor belt 22, so that smooth conveying of the sheet material 4 is ensured.
Optionally, the pressing plate 23 has a through hole 24 corresponding to the position of the conveyor belt 22, and the pressing part is disposed in the through hole 24. The lower end of the nip portion is brought into contact with the sheet material 4 through the through-hole 24, thereby pressing the sheet material 4 against the conveyor belt 22. The pressing portion may employ the balls 26, and the balls 26 roll with the sheet material 4 when the sheet material 4 moves, so that friction with the sheet material 4 can be reduced. Of course, the user may use other structural members as the material pressing portion as needed, and the present invention is not limited thereto.
Optionally, the via hole 24 is a strip hole, and the distance between the strip hole and the deviation correcting baffle 25 is gradually reduced along the direction away from the feeding table 1. When the sheet material 4 moves, the balls 26 can roll along with the sheet material 4 in a direction approaching the deviation correcting baffle 25, so that the sheet material 4 is pressed at all times.
Further, the deviation rectifying and conveying device 2 further comprises a negative pressure paper passing plate 27, the negative pressure paper passing plate 27 is located between the conveying table 21 and the feeding table 1, the negative pressure paper passing plate 27 is provided with a suction hole 28 penetrating in the thickness direction, and a negative pressure mechanism is arranged on the lower side of the negative pressure suction plate. The negative pressure mechanism adsorbs the sheet material 4 through the adsorption hole 28 to be attached to the negative pressure paper passing plate 27, and the feeding table 1 pushes the sheet material 4 to move toward the conveying table 21. The negative pressure mechanism adsorbs to enable the sheet material 4 to be flatly attached to the negative pressure paper passing plate 27, so that the negative pressure paper passing plate 27 is prevented from tilting or curling, and the sheet material can be ensured to smoothly enter the lower part of the pressing plate 23.
In this embodiment, the deviation rectifying and conveying device 2 is provided with the deviation rectifying baffle 25 along the accurate feeding direction, and the conveying belt 22 conveys the sheet material 4 to the direction close to the deviation rectifying baffle 25, so that the sheet material 4 is attached to the deviation rectifying baffle 25 and then enters the die cutting seat 3 along the direction of the deviation rectifying baffle 25, and the deviation rectifying effect is ensured. In addition, the deviation correcting conveying device 2 is further provided with a negative pressure paper passing plate 27, and the negative pressure paper passing plate 27 levels the sheet 4 through negative pressure adsorption, so that the sheet can smoothly enter the lower part of the pressing plate 23.
The structure of the loading table 1 is shown in fig. 10 or 11, and includes a mounting frame 11, a sheet peeling mechanism 13, a stock tray 12, and a blowing mechanism. Wherein, the stock tray 12 is arranged along the horizontal direction and is connected with the mounting frame 11 through the lifting mechanism 14. The stock tray 12 is provided with a stock level on which a stack of tablets can be placed. The single sheet peeling mechanism 13 is fixed above the stock tray 12 by the mounting frame 11, and the single sheet peeling mechanism 13 is capable of peeling the single sheet 4 from the stack of sheets for subsequent cutting. In addition, the mounting frame 11 is provided with a blowing mechanism which is located at one side of the stock tray 12. The blowing mechanism is used for blowing air towards the storage position, and a preset elevation angle is arranged between the air blowing direction and the horizontal plane. When the blowing mechanism discharges air, the sheet material 4 on the upper layer of the sheet material pile can be blown up, and the single stripping mechanism 13 is matched with the blowing mechanism to strip the uppermost sheet material 4 after being turned up.
The blowing mechanism blows a plurality of sheets 4 on the upper layer of the sheet pile to turn up along a preset elevation angle, the turning-up angle of one sheet 4 on the uppermost layer is the largest, and the turning-up angles of the rest sheets 4 are smaller than the turning-up angle of the other sheet 4 on the uppermost layer. At this time, the single stripping mechanism 13 adsorbs the uppermost sheet 4 through negative pressure, so that the risk of adsorbing the redundant sheet 4 can be effectively reduced, and the enterprise benefit is improved. The turning angle of the sheet material 4 is related to the air supply amount of the air blowing mechanism and the material of the sheet material 4, and the user can set the air supply amount according to the needs without limitation.
Optionally, the mounting frame 11 includes a riser 112, a bottom panel 111, and two side panels 113. The bottom plate 111 is fixedly connected with the lower part of the vertical plate 112, the side plates 113 are perpendicular to the bottom plate 111 and the vertical plate 112, and the two side plates 113 are respectively arranged on two sides of the vertical plate 112 and are fixedly connected with the vertical plate 112.
Alternatively, as shown in fig. 10, the stock tray 12 is located above the bottom plate 111. The fixed end of the lifting mechanism 14 is fixedly connected with the bottom plate 111, the movable end of the lifting mechanism 14 is fixedly connected with the stock tray 12, and the lifting mechanism 14 can drive the stock tray 12 to lift. The structure of the lifting mechanism 14 can refer to the prior art, and will not be described herein.
Optionally, the stock pallet is located between two side plates 113. The upper ends of the side plates 113 are higher than the upper ends of the vertical plates 112, and both ends of the single sheet peeling mechanism 13 are fixed by the side plates 113.
The single sheet peeling mechanism 13 includes an adsorption belt driving roller 131, an adsorption belt driven roller 137, and an adsorption vacuum tube 135, all of which are parallel to the stock tray 12. As shown in fig. 12, the suction belt driving roller 131 has a suction belt driving roller on its outer periphery, the suction belt driven roller 137 has a suction belt driven roller on its outer periphery, and the feeding suction belt 134 is mounted around the suction belt driving roller and the suction belt driven roller and is pressed against the suction belt driving roller outer periphery. The feed sorbent strip 134 is rotatable with the sorbent strip drive wheel. The suction vacuum tube 135 is located inside the feed suction belt 134 and is connected to a negative pressure device. The adsorption vacuum tube 135 is provided with an adsorption hole 28 towards one side of the sheet pile, and the sheet 4 is attached to the feeding adsorption belt 134 after being adsorbed by the negative pressure of the adsorption vacuum tube 135 and moves towards the discharge hole under the drive of the feeding adsorption belt 134.
Optionally, a plurality of adsorption belt driving wheels are arranged on the periphery of the adsorption belt driving roller 131, and the adsorption belt driving wheels are distributed along the length direction of the adsorption belt driving roller 131. The outer periphery of the adsorption belt driven roller 137 is provided with a plurality of adsorption belt driven rollers, and the adsorption belt driven rollers are in one-to-one correspondence with the adsorption belt driving wheels. Each set of suction belt drive wheel and suction belt driven wheel is provided with a feed suction belt 134 at its periphery. The plurality of feed adsorption bands 134 move the sheet 4, so that the inclination of the sheet 4 can be reduced.
Alternatively, as shown in fig. 12, the cross section of the suction vacuum tube 135 is substantially rectangular, and the side of the lower side of the suction vacuum tube 135 near the discharge port has a discharge elevation angle. The discharge elevation angle may be equal to the preset elevation angle, so that the sucked sheet 4 is conveyed to the discharge port of the feeding table 1 along the preset elevation angle. The redundant sheet material 4 can not enter the discharge hole due to smaller turning-up angle, so that the possibility of excessive feeding is reduced.
Optionally, the height of the lower side surface of the adsorption vacuum tube 135 gradually decreases with the distance from the discharge hole, so as to form a discharge lifting angle. The lower surface of the adsorption vacuum tube 135 is attached to the feed adsorption belt 134, so that the feed adsorption belt 134 also forms a discharge elevation angle. The height of the discharge hole of the feeding table 1 is higher than the lower side surface of the adsorption vacuum tube 135, and the discharge lifting angle can convey the adsorbed sheet 4 to the discharge hole.
Optionally, a baffle 138 is disposed below the single peeling mechanism 13, and two ends of the baffle 138 may be fixed by the side plates 113. The upper end of the baffle 138 is higher than the upper layer of the stack of sheets, and the sheets 4 sucked by the sheet-stripping mechanism 13 can pass over the baffle 138. When the turning angle of the sheet material 4 is smaller than the discharging lifting angle, the sheet material is blocked by the blocking sheet 138, so that the possibility of excessive feeding is further reduced.
Optionally, as shown in fig. 14, a feeding driving roller 133 is further disposed between the two side plates 113, and the feeding driving roller 133 is located on a side of the upper end of the riser 112 away from the stock tray 12, that is, the feeding driving roller 133 is located below the discharge port. A mounting beam is arranged between the upper ends of the two side plates 113, a feeding pinch roller 136 is arranged on the lower side of the mounting beam, and the feeding pinch roller 136 is positioned above the discharge hole. The feeding pinch roller 136 corresponds to the position of the feeding driving roller 133, and the feeding pinch roller and the feeding driving roller cooperate to press the sheet material 4 sent out from the discharge hole and further convey the sheet material forward.
As shown in fig. 14, a driving motor 132 is disposed on one side of the riser 112 far away from the stock tray 12, a feeding driving roller 133 and an adsorption belt driving roller 131 are respectively provided with a feeding belt wheel and an adsorption belt wheel, and the feeding driving belt compresses the outer sides of the feeding belt wheel and the adsorption belt wheel, so as to drive the feeding driving roller 133 and the adsorption belt driving roller 131 to rotate, thereby realizing the conveying of the sheet 4. Of course, other structures can be adopted by the user to drive the feeding driving roller 133 and the adsorption belt driving roller 131 to be in transmission connection with the driving motor 132.
