Description

Feeding device

Technical Field

The utility model relates to a feeding device.

Background

The mixer is used for stirring the material, the equipment of mixture, it is generally including feed arrangement, feed arrangement is including the feeder hopper, dispose the feed inlet on the feeder hopper, get into the feed cylinder and prevent the material in order to completely cut off external filth, spills such as dust, feed inlet department still disposes the door that can overturn and open and shut usually, traditional this type of door can cause the air vortex when opening and shutting, make external filth enter into the feeder hopper easily or make the material dust enter into the air, influence product quality, also cause the pollution to peripheral air easily, influence staff's health.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art, the utility model provides a can solve the feed arrangement of above-mentioned problem.

In order to achieve the purpose, the utility model provides a feeding device, including the feeder hopper, the feeder hopper is including the feed inlet, feed inlet department is provided with the door of opening and close with the feed inlet cooperation, and the door can be the door of upset, and the outside of feeder hopper is provided with rotatable roller, the flexible membrane that can pull stretch out, withdraw is accomodate around accomodating to the roll, and this membrane can press from both sides to be established between door and the feed inlet with the door cooperation is right the feed inlet seals.

The utility model has the advantages that: the membrane can follow the roller and pull out and press from both sides and establish between door and feed inlet, also can retrieve on the roller, only need when need open and close the feed inlet with the membrane slowly lifts or covers and folds or open the door, at the in-process of opening and shutting of door though still can produce the air vortex, nevertheless because the existence of membrane can not exert an influence to the feeder hopper inside, the inside dust of feeder hopper is difficult to spill over, and external filth dust also is difficult to get into the hopper.

Further, the feeder hopper outside is provided with and is used for the holding the box body of roller, the box body has the confession the film business turn over gap of box body, the gap both sides are provided with the seal lip.

The advantage of above-mentioned setting is: the membrane can be collected back to the box body when not using, isolated external dust reduces the pollution of external filth to the membrane, and then prevents to pollute the inside material of feeder hopper, improves product quality.

Further, the tip of membrane be provided with the spacing bar dog of gap cooperation.

The advantage of above-mentioned setting is: the setting of bar dog can prevent that the membrane from entering into the box body completely, makes things convenient for pull out next time.

Further, an elastic reset piece which can drive the roller to rotate towards the film retracting direction is connected to the roller.

The advantage of above-mentioned setting is: facilitating the retrieval of the membrane.

Furthermore, the edge around the feed inlet and the edge around the door all are provided with the cooperation and carry out the sealing washer pad that compresses tightly to the membrane.

The advantage of above-mentioned setting is: the pressing effect on the film is improved, and the sealing performance among the door, the film and the feeding hole is improved.

Further, the film is a plastic transparent film.

The advantage of above-mentioned setting is: the inside situation of feeder hopper is observed to the convenience.

fig. 2 is a side view of an embodiment of the present invention;

fig. 3 is an internal structure diagram of the box body according to the embodiment of the present invention.

Detailed Description

The embodiment of the feeding device of the utility model is shown in figures 1-3: including feeder hopper 1, feeder hopper 1 is including feed inlet 11, feed inlet 11 department is provided with the door 2 of opening and close with the cooperation of feed inlet 11, and the outside of feeder hopper 1 is provided with rotatable roller 3, the flexible membrane 4 that can pull the rotation to stretch out, withdraw is accomodate to the winding on the roller 3, membrane 4 can block the dust, and it is preferably the transparent film of plastics, and the convenient inside condition to feeder hopper 1 is observed, and this membrane 4 can press from both sides and establish between door 2 and the feed inlet 11 with door 2 cooperation is right feed inlet 11 seals.

The 1 outside of feeder hopper is provided with and is used for the holding box body 5 of roller 3, box body 5 has the confession 4 business turn over box body 5's gaps of membrane, the ascending both sides in gap width direction are provided with seal lip 51, and box body 5 can play the effect of preventing external dust and dirt pollution when membrane 4 does not use.

The tip of membrane 4 be provided with spacing bar dog 6 of gap fit, bar dog 6 set up on the one hand be convenient for hand to hold and hold, on the other hand can prevent that the tip of membrane 4 from entering into box body 5, facilitates the use.

An elastic restoring member (not shown), which may be a torsion spring, is connected to the roller 3 to drive the roller 3 to rotate in a direction to retract the film 3, and is disposed between the roller 3 and the case 5.

The edge all around of feed inlet 11 and the edge all around of door 2 all are provided with the cooperation and carry out the sealing washer 7 that compresses tightly to membrane 4, and the sealing washer 7 on the door can be identical with the sealing washer 7 of feed inlet 11 department just when door 2 is closed, and right membrane 4 compresses tightly.

The utility model discloses set up the air vortex that causes when above-mentioned such membrane 4 can prevent that door 2 from opening and shutting especially when overturning and opening, can prevent that external air dust filth from entering into feeder hopper 1 inside to can improve product quality, also can prevent that the material dust in the feeder hopper 1 from entering into peripheral air, reduce the pollution to the air, improve staff's security.

The above examples are only one of the preferred embodiments of the present invention, and the general changes and substitutions performed by those skilled in the art within the technical scope of the present invention are included in the protection scope of the present invention.
