Abstract
A kind of printing machine stock pump, comprise and being connected with the pump housing of discharge port, one end of the pump housing and mistake bridge chair with material feeding mouth, cross in bridge chair and be provided with transmission shaft, transmission shaft one end reached outside bridge chair, the transmission shaft the other end is connected with internal gear, internal gear and external gear toe joint, and external gear and eccentric disc cooperatively interact, the other end of the pump housing and the tail end of eccentric disc are by end bracket enclosed, and described bridge chair is excessively provided with near the end face of gear the bypass channel that the inside of material feeding mouth and mistake bridge chair is communicated.The stock pump of this structure does not have overflow hole, and operationally slurry can not flow out from original overflow hole, reaches conservation, maintains again the object of on-site sanitation.
Description
Technical field
The utility model relates to stock pump, refers in particular to printing machine stock pump.
Background technique:
Stock pump that printing machine uses, there is out an overflow hole, because internal-external gear engagement pump is while be negative pressure, while be malleation, because rotatable parts and non-rotatable member exist certain gap, though there is a mechanical seal atmospheric area, but still there is some dyes to enter atmospheric area, even spilling from overflow hole through clearance seal, cause production scene to have overflow slurry, is all a challenge to on-site sanitation and raw material management and control.
Model utility content
The purpose of this utility model is to provide a kind of by improving printing machine stock pump inside, make slurry operationally slurry can not flow out from original overflow hole, reach conservation, maintain again the object of on-site sanitation.
The technological scheme that the utility model adopts is: a kind of printing machine stock pump, comprise and being connected with the pump housing of discharge port, one end of the pump housing and mistake bridge chair with material feeding mouth, cross in bridge chair and be provided with transmission shaft, transmission shaft one end reached outside bridge chair, the transmission shaft the other end is connected with internal gear, internal gear and external gear toe joint, external gear and eccentric disc cooperatively interact, the other end of the pump housing and the tail end of eccentric disc are by end bracket enclosed, and described bridge chair is excessively provided with near the end face of gear the bypass channel that the inside of material feeding mouth and mistake bridge chair is communicated.The stock pump of this structure does not have overflow hole, and operationally slurry can not flow out from original overflow hole, reaches conservation, maintains again the object of on-site sanitation.
Described bypass channel was positioned at bridge chair end face near material feeding mouth place, and when stock pump works because internal gear band movable eccentric wheel rotates, make material feeding mouth form negative pressuren zone, discharge port forms zone of positive pressure, and the slurry entering gear just can be discharged from negative pressuren zone smoothly.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model printing machine stock pump;
Fig. 2 is that Fig. 1 removes the A-A after end cap, eccentric disc, gear to structure cross-sectional schematic.
Embodiment
Further the utility model is described in detail in conjunction with Figure of description now.
As shown in Figure 1, 2: a kind of printing machine stock pump, comprise and being connected with the pump housing 3 of discharge port 2, one end of the pump housing 3 and mistake bridge chair 4 with material feeding mouth 1, cross in bridge chair 4 and be provided with transmission shaft 5, transmission shaft 5 one end reached outside bridge chair 4, transmission shaft 5 the other end is connected with internal gear 61, internal gear 61 and external gear 62 toe joint, external gear 62 and eccentric disc 7 cooperatively interact, the other end of the pump housing 3 and the tail end of eccentric disc 7 are sealed by end cap 8, and described bridge chair 4 is excessively provided with near the end face of gear 6 bypass channel 9 that the inside of material feeding mouth 1 and mistake bridge chair 4 is communicated.The stock pump of this structure does not have overflow hole, and operationally slurry can not flow out from original overflow hole, reaches conservation, maintains again the object of on-site sanitation.
Described bypass channel 9 was positioned at bridge chair 4 end face near material feeding mouth 1 place, and when stock pump works because internal gear band movable eccentric wheel rotates, make material feeding mouth form negative pressuren zone, discharge port forms zone of positive pressure, and the slurry entering gear just can be discharged from negative pressuren zone smoothly.
Claims (2)
1. a printing machine stock pump, comprise and being connected with the pump housing of discharge port, one end of the pump housing and mistake bridge chair with material feeding mouth, cross in bridge chair and be provided with transmission shaft, transmission shaft one end reached outside bridge chair, the transmission shaft the other end is connected with internal gear, internal gear and external gear toe joint, and external gear and eccentric disc cooperatively interact, the other end of the pump housing and the tail end of eccentric disc, by end bracket enclosed, is characterized in that: described bridge chair is excessively provided with near the end face of gear the bypass channel that the inside of material feeding mouth and mistake bridge chair is communicated.
2. a kind of printing machine stock pump according to claim 1, is characterized in that: described bypass channel was positioned at bridge chair end face near material feeding mouth place.
