Description
Technical field
The utility model relates to a kind of for the automatic for fluid infusion system of gel printer, particularly a kind of stepper motor
Lead screw rotation is driven by shaft coupling, converts rotational motion into linear motion through nut, screw rod drives rubber piston along feed flow
The inside wall of cylinder is moved forward and backward, and realizes fluid infusion and feed flow process.
Background technique
Currently, conventional piston formula liquid-supplying system, installation space is larger, and the utilization rate in space is low, and traditional, pneumatic formula supplies
Liquid system, when low speed feed flow, it is easy to pressure oscillation occur, stability is poor when work, biggish in printing viscosity
When feed flow or continuous printing large scale gel, existing technical foundation also needs further to improve or innovation.
Utility model content
The technical problem to be solved by the utility model is to being supplied for gel printer under the conditions of the prior art to meet
Liquid system can be realized automatically for fluid infusion, it is proposed that and it is a kind of for the automatic for fluid infusion system of gel printer, pass through this system
It can be realized after being used up for the solution in fluid cylinder, timely determine the position of rubber piston, photo-sensor feedback signal makes
Stepper motor starts operation, and then starts fluid infusion work, realizes for fluid infusion system reciprocation cycle.
To achieve the goals above by being realized with flowering structure: it is a kind of for the automatic for fluid infusion system of gel printer,
It is characterized in that stepper motor drives lead screw to rotate by shaft coupling, linear motion, screw rod are converted rotational motion into through nut
It drives rubber piston to be moved forward and backward along the feed flow inside wall of cylinder, realizes fluid infusion and feed flow process.
Further, fluid infusion process, when rubber piston is located at right above photoelectric sensors A, photoelectric sensors A it is anti-
Feedback signal inverts stepper motor, and lead screw drives rubber piston to retreat, and sliding block is moved forward along linear guide, and unidirectional at this time
Valve A is in opening state, and check valve B is in closed state, and liquid storage cylinder liquid is flowed into feed flow cylinder through check valve A, threeway, carried out
Fluid infusion.
Further, feed flow process, when rubber piston retreats to right above photoelectric sensor B, photoelectric sensor device B feedback
Signal rotates forward stepper motor, and check valve A is in closed state at this time, and check valve B is in opening state, and rubber piston pushes
Feed flow is carried out through threeway, check valve B for liquid in fluid cylinder.
The advantages of the utility model: the utility model has the following advantages that the prior art one kind is printed for gel
Machine it is automatic for fluid infusion system, compared with conventional piston formula liquid-supplying system, reduce the installation footprint of system, improve space
Utilization rate is up to 30%, and compared with traditional, pneumatic formula liquid-supplying system, pressure is fluctuated when overcoming low speed feed flow, stability difference
Disadvantage can be used for the biggish printing fluid feed flow of viscosity, increase liquid replenishing function, provide skill for continuous printing large scale gel
Art basis, and realize automation.

Check valve B12, photoelectric sensors A 13, photoelectric sensor B14, sliding block 15, linear guide 16.In the mechanism stepper motor and
Rack is fixed by screw attachment, nut and is fixed for fluid cylinder and sliding block by screw attachment, photoelectric sensors A and photoelectric sensing
Device B and sliding block are threaded fixation, and linear guide and rack are fixed by screw attachment, stepper motor motor shaft and lead screw
Coupled by shaft coupling, rubber piston is threaded with lead screw, three end of threeway and polyfluortetraethylene pipe grafting, check valve two
End and polyfluortetraethylene pipe grafting.Lead screw and nut constitute screw thread pair, and rubber piston and the feed flow inside wall of cylinder constitute prismatic pair, sliding block
Constituting prismatic pair with linear guide can be realized after using up for the solution in fluid cylinder through such a connection manner, passes through light
Electric transducer A timely determines the position of rubber piston, and photoelectric sensors A feedback signal makes stepper motor start operation, in turn
Starting fluid infusion work, the position of rubber piston changes, retreat to photoelectric sensor B, photoelectric sensor B feedback signal, in turn
Stepper motor is started to work, and is realized for fluid infusion system reciprocation cycle.A kind of gel printer may be implemented by above-mentioned design
Automatically for fluid infusion system.
