Accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail:
Fig. 1 is the principle schematic of Copper Foil automatic cutting device of the present utility model;
Fig. 2 is the A place enlarged diagram in Fig. 1.
The specific embodiment
Copper Foil automatic cutting device as Figure 1-Figure 2, be mainly used in the Copper Foil 4 of rolling to cut and clear up cutting the copper scale and/or the copper powder that produce in process, avoid being stained with copper scale and/or copper powder on the Copper Foil 4 after cutting, also avoided copper powder to fly away in air simultaneously.
Copper Foil automatic cutting device comprises material conveying device 1 and the coiled material support 3 being fixed for the Copper Foil 4 to rolling, go out between material conveying device 1 and coiled material support 3 and be provided with the cutting means 2 that Copper Foil 4 is cut, between cutting means 2 and coiled material support 3, be provided with the press nips of carrying out feed for the Copper Foil 4 to rolling.
Cutting means 2 is the core component of Copper Foil automatic cutting device.It comprises frame 21, and frame 21 can directly be installed on ground, is provided with upper shear blade 22 and lower scissors sheet 23 that Copper Foil 4 is cut in frame 21.The effect of cooperatively interacting of upper shear blade 22 and lower scissors sheet 23 dislocation types makes shear blade 22 and lower scissors sheet 23 have the function of scissors, thereby continuous Copper Foil 4 length according to actual needs can be cut.The front-end and back-end of upper shear blade 22 are respectively arranged with carries out the suction nozzle 24 of negative pressure recovery and to the copper scale of bonding on upper shear blade 22 and lower scissors sheet 23 and/or the pressure-adjustable air blowing cutter 25 cleared up of copper powder to copper powder.Because Copper Foil 4 is to be moved toward the direction that goes out material conveying device 1 from coiled material support 3, for this reason, for ease of describing, the alleged front end of the utility model is along one end of the place ahead indication of Copper Foil 4 directions of motion, otherwise is rear end.Therefore, the front end of upper shear blade 22 is also along one end that goes out material conveying device 1 of the place ahead indication of Copper Foil 4 directions of motion.The front end of upper shear blade 22 is provided with suction nozzle 24, and the Main Function of suction nozzle 24 is that the copper powder of 4 upper surfaces of the Copper Foil after cutting is carried out to negative pressure recovery, and suction nozzle 24 is connected with outside negative pressure generation equipment.Due to after upper shear blade 22 and lower scissors sheet 23 cut Copper Foil 4, on upper shear blade 22 and lower scissors sheet 23, can be bonded with copper scale and/or copper powder, the rear end of upper shear blade 22 is provided with pressure-adjustable air blowing cutter 25, and it is mainly used in upper shear blade 22 to carry out separated with upper shear blade 22 with lower scissors sheet 23 with copper scale and/or the copper powder of bonding on lower scissors sheet 23.For preventing that the relatively large copper scale of weight from can not be picked up by suction nozzle 24, the neighboring area of suction nozzle 24 is provided with first hairbrush 241, the first hairbrush 241 that can directly contact with Copper Foil 4 and is arranged on suction nozzle 24.The first hairbrush 241, except the copper scale of Copper Foil 4 upper surfaces being swept and fallen in the first pulp-collecting box 61, can also improve the ability of the copper powder of suction nozzle 24 absorption Copper Foil 4 upper surfaces.The first pulp-collecting box 61, the first pulp-collecting box 61 that the bottom of lower scissors sheet 23 is provided with negative pressure recovery copper scale and/or copper powder are open top structure.The top of the first pulp-collecting box 61 is also provided with the silk screen 611 that Copper Foil 4 is supported and the second hairbrush 612 that Copper Foil 4 bottoms after cutting are cleaned.Silk screen 611 both supported for the rear end of the Copper Foil 4 to after cutting, and prevented that the rear end of the Copper Foil 4 after cropped from causing occurring bending distortion because losing to support; Also the front end for the Copper Foil 4 to not cutting leads, and Copper Foil 4 can successfully be entered into out on material conveying device 1, prevents that the front end of Copper Foil 4 from falling in the first pulp-collecting box 61, avoids making automated production to carry out continuously.Adopt 611 pairs of Copper Foils 4 of silk screen support and lead, can also make copper powder and/or the latticed gap of copper scale from silk screen 611 on Copper Foil 4 successfully fall in the first pulp-collecting box 61.
Press nips is for carrying out feed to being placed on the Copper Foil 4 of the rolling on coiled material support 3, is also Copper Foil 4 to rolling and carries out automatic transport power is provided, and makes it to going out material conveying device 1, carry out feed, to realize the cutting of Copper Foil 4 of rolling, can carry out continuously.Press nips comprises upper pressure wheel 51 and the lower pressure wheel 52 that axis is parallel to each other, and upper pressure wheel 51 and lower pressure wheel 52 are all fixed in frame 21 in rotating mode, and upper pressure wheel 51 and lower pressure wheel 52 rotate under the driving of motor.For preventing that upper pressure wheel 51 and lower pressure wheel 52 from damaging Copper Foil 4 and increasing the driving force of press nips to Copper Foil 4, is provided with cavernous body 50 on the radial surface of upper pressure wheel 51 and lower pressure wheel 52.
Go out material conveying device 1 and comprise discharge rack 10 and be arranged at the Belt Conveying assembly 11 on discharge rack 10, Belt Conveying assembly 11 comprises the driving belt 111 of the Copper Foil 4 after direct driving cuts.
