A kind of balata belt hole punched device
Technical field
The present invention relates to a kind of balata belt hole punched devices, belong to machinery field.
Background technique
Conveying belt is the important component on printer, is mainly used for the transmission of printer paper, to improve conveying essence
Degree and computed carrier amount needs are punched uniformly distributed aperture on belt.Mainly there are air-cylinder type punching and liquid to belt punching in the prior art
Pressure type punching.Air-cylinder type punching causes air pressure unstable since air pump does not stop gas supply, causes punch die stroke unstable, punch size
There is deviation, the single-item punching time is long, and single-piece punching needs about 90S, and flush shear force not enough can be the flash of punching surrounding
Become larger, so that production low efficiency, qualification rate are poor.Although fluid pressure type punching stroke it is more stable, also have noise and it is long when
Between use the defect for having oil leak, the higher deficiency of equipment cost.
Summary of the invention
To achieve the above object, the present invention provides a kind of balata belt hole punched device, and the present invention is as follows using technical solution:
A kind of belt hole punched device comprising rack and the workbench and controller that are arranged on the rack, the workbench
On belt rotating mechanism and belt puncher structure are installed;The belt rotating mechanism includes by servo motor A driving rotation
The tensioning shaft mobile by servo motor B drives edge horizontal guide rail of drive shaft and installation on the horizontal guide rail, the level are led
Rail is installed on the workbench;The belt puncher structure includes that cavity plate, guide plate, punch die, punch die fixed plate and straight line are watched
Motor is taken, the cavity plate is installed on the workbench by mounting plate and between the drive shaft and the tensioning shaft,
The guide plate is mounted on the top on the mounting plate and being located at the cavity plate, and the linear servo-actuator is installed by bracket
On the workbench, the output axis connection of the punch die fixed plate and the linear motor, the punch die, which is spirally connected, is mounted on institute
It states the downside of punch die fixed plate and is located at the top of the guide plate;The induction light for security protection is additionally provided in the rack
Grid, the servo motor A, servo motor B, linear servo-actuator and induction grating with the controller connection communication.
Further, there is multiple rows of formed punch on the punch die, have guiding corresponding with formed punch logical on the guide plate
Hole, the punch die and the guide plate pass through the guide pin being arranged on punch die and the pilot hole being arranged on guide plate positions.
Further, the waste discharge hopper being connected with concave die cavity is equipped in the cavity plate.
Compared with prior art, the beneficial effects of the present invention are: the present invention by using servo motor replace cylinder and
Hydraulic cylinder, stroke is more stable, and control is more convenient, die cutting accuracy and more efficient, and noise and cost are lower.The present invention passes through tensioning
The movement of axis tightens belt in drive shaft and tensioning shaft, and is turned by drive shaft driving, is driven by linear servo-actuator
Formed punch realize belt circumference punching.The present invention makes punching clout that receipts be discharged in time by the way that waste discharge hopper is arranged in cavity plate
Collection avoids blocking from causing Caton and influences punching precision.The present invention controls all driving motors using PLC controller, passes through ginseng
Number input manipulation, control precision are high.Punching die of the invention replaces convenient, different punching and requires only to need to change mold i.e.
Can, it is versatile.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention;
Fig. 2 is Working table structure schematic diagram of the invention;
Fig. 3 is punch die of the invention, guide plate and cavity die structure schematic diagram.
Specific embodiment
With reference to the accompanying drawing, the present invention is described in detail.
Embodiment:
Refering to fig. 1 shown in -3, a kind of belt hole punched device comprising rack 1 and 2 He of workbench being arranged in rack 1
Controller 3 is equipped with belt rotating mechanism and belt puncher structure on the workbench 1;The belt rotating mechanism include by
Servo motor A4 driving rotation drive shaft 5 and be mounted on horizontal guide rail 6 by servo motor B (not shown) drives edge water
The mobile tensioning shaft 7 of level gauge 6, the horizontal guide rail 6 are mounted on the workbench 2;The belt puncher structure includes recessed
Mould 8, guide plate 9, punch die 10, punch die fixed plate 11 and linear servo-actuator 12, the cavity plate 8 are mounted on institute by mounting plate 13
It states on workbench 2 and between the drive shaft 5 and the tensioning shaft 6, the guide plate 9 is mounted on the mounting plate 13
And it is located at the top of the cavity plate 8, the linear servo-actuator 12 is mounted on the workbench 2 by bracket (not shown),
The output axis connection of the punch die fixed plate 11 and the linear motor 12, the punch die 10, which is spirally connected, to be mounted on the punch die and fixes
The downside of plate 11 and the top for being located at the guide plate 9;The induction grating 14 for security protection is additionally provided in the rack 1,
The servo motor A4, servo motor B (not shown), linear servo-actuator 12 and induction grating 14 connect with the controller 3
Connect letter.
Further, there is multiple rows of formed punch 110 on the punch die 10, have on the guide plate 9 corresponding with formed punch 110
Guide through hole 90, the punch die 10 passes through the guide pin (not shown) being arranged on punch die 10 and setting with the guide plate 9
Pilot hole positioning (not shown) on guide plate 9.
Further, the waste discharge hopper 15 being connected with concave die cavity 80 is equipped in the cavity plate 8.
The course of work of hole punched device of the invention are as follows: required, inputted by controller related according to belt punching first
Control parameter, by belt sleeve in drive shaft and tensioning shaft, movement makes belt tension, servo to servo motor B on the horizontal guide rail
Motor A driving drive shaft rotates belt, and linear servo-actuator driving punch die, which pumps, is punched out belt, punching
Waste material falls into the discharge of waste discharge hopper through concave die cavity, and one ring through hole of belt, which shuts down to take out after being punched, enters subsequent cycle.It is single
Product are punched within cycle time to 20S, and precision is high, speed is fast.
The above is a preferred embodiment of the present invention, it is noted that for those skilled in the art
For, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also considered as
Protection scope of the present invention.
