Detailed Description

The following description of the embodiments of the present invention refers to the accompanying drawings.

As shown in fig. 2, 3 and 4, the non-weighing quantitative filling device of the present invention is fixed to the bottom of the hopper 2 by a flange 7. As shown in fig. 5 to 10, a hole is formed in the middle of the flange 7, a barrel 15 with a spindle-shaped cross section is arranged below the hole, two vertical plates 14 and fixing pieces 8 are symmetrically arranged at two tip ends of the spindle shape in the barrel 15, the vertical plates 14 are connected with the fixing pieces 8, the vertical plates 14 are slightly inclined and matched with the barrel 15 to form a middle blanking channel 6 and two outer side spaces, a first air cylinder 9 is respectively arranged in each outer side space, and the first air cylinders 9 are locked on the upper fixing pieces 8 through bolts. Be provided with two relative claw types in the bottom of barrel 15 and get material and turn over board 4, get the root 42 pin joint of turning over board 4 in riser 14 bottom to on the piston rod of first cylinder 9, the upset of turning over board 4 is got in the drive when first cylinder 9 stretches out and draws back, two are got when turning up the level and are got the finger portion 41 of turning over board 4 and mutual, seal with the shutoff material bottom unloading passageway 6, get to turn over board 4 and open unloading passageway 6 when falling vertically. As shown in fig. 7 and 8, two reinforcing ribs 16 are provided at the bottom of the material taking flap 4 to enhance the bearing capacity of the material taking flap 4. The bag clamping mechanism comprises a pair of clamping blocks 13 and a second air cylinder 10 used for driving the clamping blocks 13, the clamping blocks 13 and the second air cylinder 10 are pivoted on the flange 7 through a pair of supports 12, the two pairs of supports 12 are connected through a connecting rod 11, soft straps (not shown in the figure) are further arranged at the bottoms of the two pairs of supports 12, and when the clamping blocks 13 are clamped, the straps tightly clamp the bag opening at the periphery of the bottom of the barrel 15. The flange 7 may be square, circular or oval, and the cylinder 15 may also be square, circular or oval.

In actual work, the packaging bags 5 are filled with materials, the bag mouth parts of the materials are taken out through the weighing-free quantitative filling device, and the quantity of the taken-out materials just meets the height requirement of the sealing of the packaging bags 5. The specific process is as follows: the invention normally closes the material taking turning plate 4, and closes the materials to be filled in the hopper 2 as shown in figure 2. When the packaging bag needs to be filled, the packaging bag 5 is sleeved on the periphery of the bottom of the cylinder 15, the second air cylinder 10 is started, the second air cylinder 10 drives the clamping block 13 and the strap to clamp the packaging bag 5, and the bag opening is guaranteed to be tightly clamped on the periphery of the bottom of the cylinder 15. As shown in fig. 3, the first cylinder 9 is actuated to open the material taking flap 4, and the material in the hopper 2 falls into the packaging bag 5 through the discharging channel 6 under the action of gravity. As shown in fig. 4, when the packaging bag 5 is completely filled, the material does not descend any more; at this moment, the first air cylinder 9 is started, the first air cylinder 9 drives the material taking turning plate 4 to rotate inwards and upwards by taking the root 42 as a rotation center until the finger part 41 of the material taking turning plate 4 abuts against the first air cylinder, when the material taking turning plate 4 is turned and ascended to restore to an initial position, on one hand, the material flow of the pouring bag is pinched off, the blanking channel 6 is sealed, and meanwhile, partial material at the opening of the packaging bag 5 is fished back into the hopper 2, so that the distance enough for sewing the opening of the sewing machine is reserved at the upper part of the packaging bag 5. Then, the second cylinder 10 operates to open the clamp block 13, the packing bag 5 is separated from the bottom of the cylinder 15, and finally the mouth of the packing bag 5 can be sewn. Because the size and the stroke of the material taking turning plate 4 are fixed, the material amount fished back from the packaging bag 5 can be ensured to be the same, so that the distance of the opening part is ensured to be constant, and the purpose of quantitative filling without weighing is realized. By controlling the height change of the packaging bag 5 sleeved on the barrel 15 part, the depth of the material taking turning plate 4 extending into the packaging bag 5 is changed, so that different bag filling quantities are realized, and the seam distance required by different seam sewing machines is met.

The foregoing description is illustrative of the present invention and is not to be construed as limiting thereof, as the invention may be modified in any manner without departing from the spirit thereof. The motor can be used for replacing the first cylinder 9 to drive the material taking turning plate 4, or common transmission devices such as gears and chains are used, the material taking turning plate 4 is only required to be driven to turn, and partial materials at the bag opening are fished up. The material taking turning plate 4 is not limited to a claw shape, the number is not limited to two, and only the requirement of sealing the bottom of the blanking channel 6 is met.
