Specific embodiment
Specific embodiment of the present utility model is further described with reference to the accompanying drawing.
The purpose of the utility model is to provide a kind of full-automatic capillary cutter device, self-feeding, automatic can be realized
It cuts and guarantees consistency, improve cutting working efficiency.
The adjustable capillary rapid cutting device of fixed length as shown in Figures 1 to 7, the structure of the device is mainly by three parts
Function composition：Feeding, cutting-up and blanking.Capillary 3 is wrapped on charging tray 1 under original state, and charging tray 1 is mounted on charging tray frame 2
In shaft, charging tray frame 2 and bracket 14 are fixed, and bracket 14 is mounted on above chassis 15.In use, capillary 3 passes through guide holder 4
Aperture is sandwiched between drive roll 11 and passive guide roller 13 (referring to fig. 4), and two rollers realize elastic tensioning by tension spring 12, is protected
It demonstrate,proves when the rotation of the axis of the stepper motor 5 with 11 connecting shaft of drive roll, under frictional force effect, head travels forward capillary.Hair
The amount of feeding of tubule is obtained by the conversion of the received step number of stepper motor 5.It is positive to locate when capillary 3 is sent to the length that need to be cut
In the position of cleavage block 6.Push-rod electric machine 7 drags push rod 20 backward, has driven tool apron 16, and tool apron 16 has two pins 18 above,
Two pins 18 can only slide in the specific sliding slot 21 and 22 of guide holder 19, to realize the cutting being mounted on tool apron 16
Cutting-up movement (only in upper surface leave a thin scratch, directly do not cut off) of the knife 17 to 3 upper surface of capillary.Push-rod electric machine
7 reversions, push rod 20 travel forward, and cutter 17 are lifted (referring to Fig. 7 a).
Wherein, two pins 18 in left and right are mutually fixed with tool apron, and the pin in left side is matched with sliding slot 21, and in outer power drive
Under can slide back and forth at 21 both ends along the chute, sliding slot 21 is arcuate structure, and left end is high, and right end is low.The then pin with right side of sliding slot 22
It matches, sliding slot 22 is horizontal concrete chute.When left side pin 18 along the chute 21 by right side fail to agree side displacement (move from low to high
Position) when, the cutter head lifting of cutter 17 is driven, and then realize the evacuation to capillary, so that the hair of sliding cutting is completed on surface
Tubule continues forward, to advance to next process.
Also, height of the right end of sliding slot 21 preferably with sliding slot 22 is consistent, also, sliding slot 21 close to right end portion most
It is also provided with one section of horizontal groove body well.
Under the operating of stepper motor 5, the cutting position of capillary 3 is sent to the exit of blanking lower die 8.Blanking lower die
Effect be in blanking, the position of capillary it is substantially stationary live, keep fracture more neat.Blanking motor 10 operates, and drives
Blanking knife 9 moves downward.Capillary under the action of the shearing force of both sides, concentrate in addition by the stress at cutting-up, fracture.In computer
It is above to act in cycles under the control of (single-chip microcontroller) program, so that the fixed length to capillary, continuous, automatic cutting can be realized.
