the existing reciprocating pump cannot accurately control the extrusion quantity;
the existing reciprocating pump cannot realize continuous feeding.
Disclosure of Invention
The utility model provides a continuous discharging system.
The technical scheme of the utility model is as follows:
the utility model provides a glue spraying machine or mix reciprocating type feed pump for gum machine, the feed pump includes cylinder body, piston, the cylinder body is a sealed drum, and its one end is provided with feed inlet, discharge gate, the piston is installed in the cylinder body, with cylinder body sliding seal cooperation, the piston is relative with feed inlet, discharge gate, install drive arrangement on the cylinder body, drive arrangement connects the piston, and reciprocating type motion is done in the cylinder body to the drive piston, inhales material or the extrusion material of discharge gate by the feed inlet.
The driving device is formed by connecting a motor with a screw rod and a screw rod nut, wherein the screw rod is inserted into the cylinder body directly and connected with the piston, and the driving device stretches and contracts under the cooperation of the motor and the screw rod nut to drive the piston to do reciprocating motion in the cylinder body.
The cylinder body is provided with a worm and gear mechanism, and the worm and gear mechanism is connected with a motor and a screw nut.
And the cylinder body is also provided with a screw rod sheath, and the screw rod sheath covers the part of the screw rod outside the cylinder body.
A continuous discharging system comprising a plurality of reciprocating feed pumps for the showers or blenders;
a PLC control system is connected with all the reciprocating feed pumps to control the linkage of all the reciprocating feed pumps, the reciprocating feed pumps are divided into a plurality of groups, each group of at least two reciprocating feed pumps are in the same group of reciprocating feed pumps, and all the reciprocating feed pumps alternately suck or extrude the same component materials.
The utility model has the advantages that the design is reasonable, the structure is simple, the material is sucked or extruded through the reciprocating motion of the piston, the impact of particulate matter blockage is avoided, the pump pressure balance is continuously ensured, the extrusion material quantity (extrusion material quantity=piston stroke x cylinder section) can be accurately controlled, and the fault rate is greatly reduced; considering that the reciprocating feed pump is used for realizing intermittent discharge once in one-time return of single cylinder operation, the continuous discharge is realized by adopting a plurality of reciprocating feed pumps to link, and when one reciprocating feed pump extrudes the material, the rest reciprocating feed pumps pump the material; and driving and distributing the plurality of single-cylinder reciprocating feed pumps according to different instructions of setting parameters, so as to achieve the aim of accurate proportion distribution.
