Technical Field

[0001] The utility model relates to the field of bagging, in particular to a bag supporting device for material receiving. Background Technique

[0002] Water-soluble fertilizer refers to liquid or solid fertilizers that are dissolved or diluted in water and used for irrigation fertilization, foliar fertilization, soilless cultivation, seed soaking and root dipping, etc. According to their forms and nutrient contents, water-soluble fertilizers can be divided into various types, including solid water-soluble fertilizers (such as powders, granules) and liquid water-soluble fertilizers (such as clear liquids, suspensions), as well as water-soluble fertilizers containing macronutrients, water-soluble fertilizers containing micronutrients, water-soluble fertilizers containing amino acids, water-soluble fertilizers containing humic acids, organic water-soluble fertilizers, etc.

[0003] In the production process of water-soluble fertilizer, it is necessary to bag the water-soluble fertilizer. In a semi-automatic production line, although some links have been automated, manual assistance may still be required during the bagging process. Workers need to put the packaging bag on the discharge port of the packaging machine and perform operations such as sealing or handling and stacking. Although these operations require manual participation, for example, a water-soluble fertilizer bagging device disclosed in Chinese Patent CN202320571103.8 includes a discharge pipe, at least two screws are evenly distributed on the outer side of the discharge pipe, a fixing block is sleeved on the outer side of the screw, the fixing block is movable on the screw, the lower end of the fixing block is connected to a support rod through a connecting rod, and a spring clip is arranged above the support rod.

The locking mechanism includes a movable column 21 provided on the outer wall body of the outer annular rotating block 2, and a strip-shaped movable groove 24 that penetrates the outer periphery of the outer annular rotating block 2 and is parallel to the bottom end surface of the outer annular rotating block 2, and also includes a locking rod 22, one end of which is rotatably connected to one end of the strip-shaped movable groove wall and the other end of which is bent and extended outside the strip-shaped movable groove 24 after extending in the direction of the strip-shaped movable groove 24, and the locking rod 22 is in contact with the flange 12 in the strip-shaped movable groove 24, and a locking mechanism is provided at the contacting position as shown in the figure. Figure 7 The protrusion 23 shown in the figure, the upper end surface of the flange 12 is arranged around the protrusion 23 to cooperate with the Figure 6 The fixing groove 13 shown, the protrusion 23 and the fixing groove 13 cooperate to make the outer annular rotating block 2 only rotate axially to one side, and rotating the locking rod 22 upward can make the protrusion 23 disengage from the fixing groove 13 so that the outer annular rotating block 2 can rotate freely.

[0030] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, it also includes a plurality of bag-supporting rods 3 installed at the bottom of the inner sleeve 1, the bag-supporting rods 3 are coplanar with the bottom surface of the inner sleeve 1, and one end of the bag-supporting rods 3 is rotatably connected to the bottom surface of the inner sleeve 1, and the middle of the bag-supporting rods 3 is movably connected to the bottom surface of the outer annular rotating block 2, so that when the outer annular rotating block 2 rotates relative to the inner sleeve 1, it drives the bag-supporting rods 3 to rotate with the end connected to the inner sleeve 1 as the axis, changing the distance between the end of the bag-supporting rods 3 away from the connection with the inner sleeve 1 and the axis of the inner sleeve 1. Preferably, a rotating shaft 33 perpendicular to the end surface is provided on the inner sleeve 1 of the bag-supporting surface, one end of the bag-supporting rods 3 is rotatably provided on the rotating shaft 33, a strip hole 34 is provided on the bag-supporting rods 3, and a movable shaft 32 perpendicular to the end surface is provided at a position corresponding to the strip hole 34 on the outer annular rotating block 2, and the movable shaft 32 passes through the strip hole 34. Preferably, a slider 31 is provided on the movable shaft 32, the slider 31 is clamped in the strip hole 34 and can slide along the strip hole 34, and the slider 31 protrudes from the strip hole 34 toward the side away from the movable shaft 32, and there are protrusions extending toward both sides on both sides of the slider 31, and the protrusions play a role in clamping the bag-supporting rod 3, and the slider plays a role in reducing the friction between the movable shaft 32 and the strip hole 34 and can provide a certain upward support force to the bag-supporting rod 3, so that the bag-supporting rod will not sag. Preferably, the bag-supporting rod 3 is an arc-shaped rod protruding toward the side away from the axis of the inner sleeve 1. Preferably, the arc surface of the bag-supporting rod 3 in contact with the packaging bag is provided with an array of anti-slip protrusions 35 inclined toward the opening direction of the bag-supporting rod 3, so as to increase the friction between the packaging bag and the bag-supporting rod 3 and prevent the packaging bag from falling off.

[0031] like Figure 1 As shown, preferably, a fixing device is provided at the upper end of the inner sleeve 1, including fixing holes arranged on the side of the inner sleeve 1 away from the bag-supporting surface. The fixing holes are evenly arranged on the main body of the inner sleeve 1 and fixing bolts 11 are arranged in the fixing holes, so that the device can be firmly fixed on the material receiving pipe and is easy to disassemble.

[0032] The working principle and use method of the utility model are as follows:

[0033] First check whether the bag support rod 3 of the device is in a retracted state. If so, Figure 8In the shown open state, lift the locking rod 22 to make the bump 23 of the locking rod 22 leave the fixing groove 13. After the bump 23 leaves the fixing groove 13, the outer annular rotating block 2 can freely rotate on the inner sleeve 1. After adjusting the expansion and contraction state of the bag-supporting rod 3 to an appropriate state, the device can be installed at the bottom of the feeding pipeline. Loosen the fixing bolt 11 on the inner sleeve 1, then the device can be sleeved on the feeding pipeline. After finding a suitable position, tighten the fixing bolt 11, and the installation of the device is completed. Before feeding, it is only necessary to open a small part of the packaging bag so that it can be sleeved on the bag-supporting device. Then, push the moving column 21 counterclockwise. At this time, the bump 23 of the locking rod 22 will receive a lateral force. This lateral force is decomposed into an upward acting force on the inclined wall of its bump 23, and the bump 23 is lifted, enabling the outer annular rotating block 2 to rotate smoothly. When rotating, all the bag-supporting rods 3 rotate around the rotating shaft 33 on the inner ring sleeve, driven by the movable shaft 32 and the slider 31 on the outer annular rotating block 2, until the packaging bag is lifted to Figure 8 the state shown. After the packaging bag is lifted, it will give a resistance to the bag-supporting rod 3, and this resistance makes the bag-supporting rod 3 unable to continue expanding. At this time, the pushing of the moving column 21 can be stopped. At this time, the bump 23 falls back into the fixing groove 13, and the bag-supporting rod 3 is fixed in the existing state, keeping the packaging bag lifted. It should be noted that the bottom of the packaging bag is in contact with the ground, so it is not necessary for this device to bear too much weight of the packaging bag. Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
