So that top board 91 is close to each other under the squeezing action of scissors mechanism 74 with lower platen 92, so that top board 91 and pushing
Plate 92 presses elastic balloon 43 simultaneously, increases the compressed amount of elastic balloon 43, and then improves the storage of the gas in air storage chamber 8
Standby speed, improves ball serving device to the utilization efficiency of the energy of scissors mechanism 74, has saved cost.
As shown in figure 3, being equipped with No. two rectangular enclosures 631 and slideway 632 in No. two belt wheels 63, slideway 632 is by No. two
Rectangular enclosure 631 is connected with the circular through hole 68 of No. two belt wheels 63；Movable block is additionally provided in No. two rectangular enclosures 631
633, movable block 633 is connected with the convex block 69 of lower section in circular through hole 68, and movable block 633 moves down on convex block 69 for driving
It is dynamic；No. two belt wheels 63 are equipped with bolt 634, and bolt 634 passes through No. two belt wheels 63 and is in contact with movable block 633, bolt 634
For compressing movable block 633.When work, the presence of movable block 633 enable the lower section of circular through hole 68 convex block 69 on move down
Dynamic, to facilitate the replacement and adjusting of transmitting spring 65, the damage for avoiding transmitting spring 65 causes ball serving device to scrap, and mentions
The high practicability of ball serving device.
As shown in Figure 1, the bottom plate 5 is rubber material, bottom plate 5 is equipped with ash-falling hole, and ash-falling hole is for avoiding bottom plate 5
Dust accretions.When work, when expelling plate 66 emits table tennis, because bottom plate 5 is rubber material, so that table tennis falls on bottom plate 5
It will not be bounced when upper, and avoid table tennis and fallen from bottom plate 5, while rubber material enables bottom plate 5 to shake, so that
Dust on bottom plate 5 is fallen from the ash-falling hole on bottom plate 5, is avoided the dust on bottom plate 5 and is gathered and is not easily cleaned, and hair is avoided
The dust penetrated on plate 66 causes to hinder to the steering adjusting of expelling plate 66, while avoiding the table tennis launched and being attached to dust,
Improve the practicability of ball serving device.
Specific workflow is as follows:
When work, table tennis falls in ball bucket 3 from feeding and slides along bottom plate 5 to expelling plate 66, at this point, by storing power
Module 7 drives No. two magnet 71 to move down, so that No.1 magnet 67 drives expelling plate 66 to move down, so that transmitting spring 65 is drawn
It is long, when gravitation of No. two magnet 71 to No.1 magnet 67 is attracted insufficient for No.1 magnet 67 and No. two magnet 71, transmitting
66 moment of plate is detached from, so that table tennis is launched, in the process, controller controls No.1 motor 61 and works, so that No.1
Motor 61 drives No.1 belt wheel 62 to rotate, and conveyer belt 64 rotates No. two belt wheels 63 with No.1 belt wheel 62, so that circle
Convex block 69 in shape through-hole 68 rotates and squeezes upward or downward transmitting spring 65, so that transmitting spring 65 is elongated or presses
Contracting, so that the transmitting dynamics of table tennis is adjusted, improves the practical of ball serving device so that the elasticity of transmitting spring 65 changes
Property, further make the operating time of the No.1 motor 61 of two sides different by controller, so that the transmitting spring 65 of two sides
Compression or elongation are different, so that the launch angle in table tennis horizontal direction is adjusted, further improve
The practicability of ball serving device.
When expelling plate 66 is located at minimum serving position, expelling plate 66 is vertical with bottom plate 5, the rotation of 664 end of rotation adjusting lever
Button 668, so that adjusting block 663 and expelling plate 66 rotate, so that the angle between expelling plate 66 and bottom plate 5 becomes larger, so that
Launch angle on table tennis vertical direction is changed, and effectively raises the practicability of ball serving device, adjusting block 663 and peace
The screw thread for filling block 662 is arranged so that adjusting block 663 can only move horizontally in the course of rotation, and the presence of spring to adjust
Block 663 is extruded, so that the pressure between adjusting block 663 and the screw thread of mounting blocks 662 becomes larger, so that adjusting block
Frictional force between 663 and mounting blocks 662 becomes larger, and avoids adjusting block 663 and rotates easily in mounting blocks 662, so that adjusting
Angle afterwards will not change easily, to effectively raise the practicability of ball serving device.
No. two motors 75 rotate, so that two No.1 sliding blocks 72 are close to each other or are located remotely from each other, so that scissors mechanism
74 elongate or shorten, so that No. two sliding blocks 73 are close to each other or separate, so that No. two sliding blocks 73 drive support plate 77 and two
Number magnet 71 moves up and down, and when No. two magnet 71 are close to No.1 magnet 67, No.1 magnet 67 and No. two magnet 71 are adsorbed on one
It rises, when No. two magnet 71 move downward, No.1 magnet 67 is moved downward with No. two magnet 71, and No.1 magnet 67 drives transmitting
Plate 66 moves downward and elongates transmitting spring 65, and final No. two magnet 71 and No.1 magnet 67 are detached from, so that transmitting 65 band of spring
Dynamic expelling plate 66 launches table tennis, and when scissors mechanism 74 elongates or shortens, stripper plate 9 is under the action of scissors mechanism 74
It contacts and is detached from elastic balloon 43, so that elastic balloon 43 is delivered the gas in air storage chamber 8 by unidirectional air outlet valve,
And gas is absorbed from the external world by breather cheek valve, realize the deposit of gas, reasonable utilization scissors mechanism 74 movement produces
Raw energy avoids the waste of energy, through air storage chamber 8 and gas-guide tube 667 into the No.1 rectangular enclosure 665 of expelling plate 66
Gas, and the gas flow being input in the No.1 rectangular enclosure 665 of 66 two sides of expelling plate by control are inputted, so that expelling plate 66
The elasticity of two sides is different, so that the launch angle of table tennis is finely tuned, so that the launch angle of table tennis is adjusted more
Precisely, and table tennis is rotated during transmitting because of two sides stress difference, improves the practicability of ball serving device.
When scissors mechanism 74 is shunk, the presence of connecting rod 44 makes top board 91 and lower platen 92 squeezing in scissors mechanism 74
It is close to each other under pressure effect, so that top board 91 and lower platen 92 press elastic balloon 43 simultaneously, increase elastic balloon
43 compressed amount, and then the reserve of gas speed in air storage chamber 8 is improved, ball serving device is improved to the energy of scissors mechanism 74
The utilization efficiency of amount, has saved cost.
The presence of movable block 633 enables the convex block 69 of 68 lower section of circular through hole to move up and down, to facilitate transmitting
The replacement and adjusting of spring 65, the damage for avoiding transmitting spring 65 cause ball serving device to scrap, improve the reality of ball serving device
The property used.
When expelling plate 66 emits table tennis, because bottom plate 5 is rubber material, so that table tennis will not when falling on bottom plate 5
It bounces, avoids table tennis and fallen from bottom plate 5, while rubber material enables bottom plate 5 to shake, so that on bottom plate 5
Dust fallen from the ash-falling hole on bottom plate 5, avoid the dust on bottom plate 5 and gather and be not easily cleaned, avoid expelling plate 66
On dust the steering of expelling plate 66 adjusting is caused to hinder, while avoiding the table tennis launched and being attached to dust, improve
The practicability of ball serving device.
More than, it is illustrated about one embodiment of the present invention, but the present invention is not limited to the above embodiments, not
Various changes are able to carry out in the range of disengaging present subject matter.
Industrial applicibility
