Technical Field
The invention relates to an eccentric pneumatic feeding device and a feeding system.
Background
In the production feeding process, because the raw material weight of each bag of the ton bag is different from the feeding demand at every turn, the material feeding port of the ton bag is required to be wrapped after the feeding is finished at every turn, the material leakage risk can be caused if the material is not wrapped well, and the feeding weight is inaccurate if the weight is judged inaccurately, glue is required to be added again or the raw material is added again, the working efficiency is reduced, and the risk of quality fluctuation is increased.
Disclosure of Invention
Aiming at the problems, the invention provides an eccentric pneumatic feeding device and a feeding system, which greatly increase the feeding accuracy, improve the working efficiency, avoid the risk of material leakage and reduce the risk of quality fluctuation.
In order to achieve the technical purpose and achieve the technical effect, the invention is realized by the following technical scheme:
the utility model provides an eccentric pneumatic feeding device, includes the feeder hopper, the feeder hopper below is provided with the cavity support, cavity support below is provided with the discharge gate, the through-hole that the thickness and the cavity support that the cavity support had the settlement are provided with intercommunication discharge gate and feeder hopper, the cavity support embeds has mobilizable fly leaf, the fly leaf is opened or closed through-hole through the removal.
Preferably, the hollow support is provided with a cylinder and a valve controlling the cylinder, the cylinder is connected with the movable plate and the cylinder brings the movable plate to move along the radial direction of the through hole.
Preferably, the valve is a two-position five-way manual valve.
Preferably, the feed hopper and the discharge port are arranged non-coaxially.
Preferably, a plurality of supporting rods are arranged at the outlet of the feed hopper.
Preferably, the feeder hopper is wide hollow structure narrow down, the first half of discharge gate is wide hollow structure narrow down, the latter half of discharge gate is hollow cylinder structure.
The eccentric pneumatic feeding system comprises a mixing tank, wherein a tonnage display and a weighing sensor are arranged on the mixing tank, the eccentric pneumatic feeding device further comprises any one of the eccentric pneumatic feeding devices, and the mixing tank feeds materials through the eccentric pneumatic feeding devices.
Preferably, still include the driving a vehicle, the driving a vehicle is provided with the lifting hook that is used for hoisting ton package.
The invention has the beneficial effects that:
hang ton package to blending tank mouth top by the driving during the material of throwing, untie ton package discharge gate and place in the feeder hopper of throwing the material device after untiing, begin to throw the material, throw after the material reachs required weight (required weight is judged according to the weight that the electronic metering instrument on the blending tank shows), throw the material device and can block out self-made fly leaf (also cut off) through the cylinder and plug up the dog-house (the dog-house plugs up back ton package discharge gate and no longer needs to wrap), thereby separate the raw materials, keep apart remaining raw materials in ton package, open the valve again when waiting to throw the material next time and throw the material. The device can increase the accuracy of feeding and improve the working efficiency, avoids the risk of material leakage and also reduces the risk of quality fluctuation.
