Description

Technical Field

[0001] The utility model relates to the technical field of starch products, in particular to an automatic packaging device for starch products. Background Art

[0002] After starch is processed, it needs to be packaged using a packaging machine before it can be transported to the market. Existing powder packaging machines generally include a feed hopper, a frame for installing the feed hopper, and packaging equipment. When working, starch is first poured into the feed hopper, and then transported into the packaging bag in the packaging equipment to complete the packaging.

[0003] In the related art, a Chinese patent document with application number CN202323340131.8 proposes a packaging device for starch production, which includes a filling cylinder and a conveyor belt. A motor is fixed on the surface of the filling cylinder, and a conveying auger is fixed on the driving shaft end of the motor. A discharge pipe mouth is arranged at the lower end of the filling cylinder, and a telescopic cylinder is connected to the outer surface of the discharge pipe mouth. A circular cavity shell is arranged at the lower end of the telescopic cylinder, and a conical mouth is arranged at the bottom of the circular cavity shell. A worm fan is installed on the side of the filling cylinder, and a suction pipe is fixed outside the suction port of the worm fan. The tube is fixed on the inner surface of the circular cavity shell. When in use, the conveyor belt transports the packaging tube to the bottom of the tapered mouth, and the telescopic tube is driven down by the cylinder to insert the tapered mouth into the surface of the packaging tube. The lower surface of the circular cavity shell fits the packaging tube without leakage. During filling, the conveying auger is driven by the motor to transport the starch for filling. After filling, starch will float. At this time, a collecting tube is fixed on the outside of the worm turbine fan, and a dust removal bag is fixed on the inner surface of the lower end of the collecting tube. The dust can be sucked by the worm turbine fan and filtered and collected by the dust removal bag, so that the floating dust can be filtered.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the device sucks dust through a worm fan and collects it through filtering through dust bags, so as to filter floating dust, but the existing bag dust collector does not have the function of cleaning the dust on the surface of the dust bags. When cleaning the dust bags, the dust treatment equipment needs to be disassembled, which is time-consuming and labor-intensive, and increases the maintenance costs. In view of this, an automatic packaging device for starch products is proposed to solve the above problems. Utility Model Content

[0005] The main purpose of the utility model is to provide an automatic packaging device for starch products, which solves the problems raised in the above-mentioned background technology.

[0007] The collecting mechanism includes a collecting box, which is fixed on the side of the filling cylinder, and the air outlet pipe is fixed on the inner surface of the collecting box. A fixing plate is fixed in the collecting box, and a placement groove is provided on the fixing plate. The placement groove passes through the fixing plate, and a dust removal bag is fixed in the placement groove. A cylinder is vertically arranged on the collecting box, and the output end of the cylinder passes through the fixing plate and is slidably connected to the fixing plate, and a horizontal plate is fixed thereto. A through hole is provided on the horizontal plate, and a fixing ring is rotatably installed in the through hole, and a plastic brush is fixed on the inner side of the fixing ring. An exhaust pipe is fixed to the upper end of the collecting box.

[0008] Furthermore, the fixing ring is located at the periphery of the dust bag, and the plastic brush is slidably connected to the dust bag.

[0009] Furthermore, an outer gear ring is fixed on the fixing ring, a motor is fixed on the transverse plate, a gear is fixed on the output end of the motor, and the gear meshes with the outer gear ring.

[0010] Furthermore, a dustproof protective cover is movably connected to the periphery of the motor, and the bottom of the dustproof protective cover is bolted to the bottom of the transverse plate through a fixing member.

[0011] Furthermore, the width of the transverse plate is smaller than the width of the fixed plate, and the transverse plate is slidably connected to the inner peripheral wall of the collection box.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] The automatic packaging device for starch products can drive the horizontal plate to descend by starting the cylinder when it is necessary to clean the dust on the surface of the dust bag. The fixed ring on the horizontal plate will move around the outside of the dust bag, and the plastic brush on the inner wall of the fixed ring will continuously clean the dust on the surface of the dust bag. The cleaned dust will fall under the collection box, thereby continuously cleaning the dust on the surface of the dust bag, avoiding the accumulation of condensed dust that blocks the mesh holes on the dust bag, and prolonging the service life of the dust bag.
