Description

Technical Field

[0001] The utility model relates to the technical field of feeding and conveying equipment, in particular to a raw material feeding station. Background Art

[0002] At present, in the production process, most of the raw materials needed are stored in ton bags. And when there is a large quantity of incoming materials, ton bags are not easy to store and stack. Therefore, it is necessary to use feeding and conveying equipment to put the ton bags into a large raw material bin to complete the storage and stacking of raw materials.

[0003] When the existing feeding and conveying equipment is actually used, most of them use a forklift or a crane to lift the ton bag to the feeding port, so that the raw materials in the ton bag flow into the storage hopper naturally, and then use the conveying equipment to transport the raw materials into the bin. However, during the feeding process, the raw materials in the ton bag are often difficult to slide down quickly, and there will be raw materials remaining in the ton bag, which increases the loss of raw materials during the conveying process, resulting in waste of raw materials, and thus is not conducive to the efficient feeding of raw materials. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a raw material feeding station to solve the above deficiencies in the technology.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a raw material feeding station, including a bracket, inside which a storage hopper is arranged, and a detachable ton bag feeding port is arranged at the top of the bracket. The ton bag feeding port is communicated with the storage hopper. The bottom end of the storage hopper is connected with a positive pressure airtight feeder, and an air inlet is arranged on one side of the positive pressure airtight feeder, and a discharge port is arranged on the other side;

[0006] A ton bag flapping structure is also arranged at the top of the bracket, and the ton bag flapping structure includes two rotatable flapping frames and a driving member for driving the two flapping frames to swing reciprocally. The two flapping frames are symmetrically distributed on both sides of the ton bag feeding port.

[0007] Preferably, a shaft rod is fixed on one side of each of the two flapping frames, and bearing seats are installed at both ends of the two shaft rods. The four bearing seats are all fixed on the top of the bracket.

[0008] Preferably, the driving member includes two flapping frame cylinders hinged inside the bracket. The top ends of the two flapping frame cylinders are both hinged with bent-arc connecting rods, and one ends of the two connecting rods are respectively installed on the corresponding shaft rods.

[0009] Preferably, a linkage member is also connected between the two shaft rods, and the linkage member includes a gear box installed on the bracket. One ends of the two shaft rods both extend into the gear box and are installed with meshing gears.

[0010] Preferably, a dust removal component is further arranged on the bracket, and the dust removal component includes a pulse dust collector installed on the bracket, and the dust suction end of the pulse dust collector is located above the storage hopper.

[0011] Preferably, an air escape chamber is further arranged on one side of the positive pressure airtight feeder, and an exhaust pipe extending above the storage hopper is connected to the top of the air escape chamber.

[0012] In the above technical solution, the technical effects and advantages provided by the present utility model are as follows:

[0013] 1. Through the setting of the ton bag flapping structure, when the ton bag is discharging materials, the shaft rod can be driven to rotate through the cooperation of the flapping frame cylinder and the connecting rod, and then the shaft rod drives the two flapping frames to swing reciprocally to continuously flap the ton bag, so that the materials in the ton bag are more likely to slide down and flow into the storage hopper, and the residue of the materials in the ton bag can be reduced, the loss of the materials during the conveying process can be reduced, the waste of the materials can be avoided, and thus it is beneficial to the efficient feeding of the materials;

[0014] 2. Through the setting of the linkage member, the linkage of the two flapping frames can be realized, and when driving the flapping frames to flap the ton bag, the thrust of the two layers of cylinders is preferentially distributed. If the ton bag is placed unevenly, the problem that one flapping frame is overloaded and cannot perform the bag flapping work, and only one flapping frame works and cannot quickly and effectively clean the materials in the ton bag can be effectively avoided, and the rapid sliding of the materials in the ton bag can be further realized;

[0015] 3. Through the setting of the dust removal component, during the feeding process, the pulse dust collector forms a micro-negative pressure state above the storage hopper through its dust suction end, and sucks away the dust generated in the storage hopper during the feeding process, so that no a large amount of dust overflows during the feeding process, the dust pollution of the surrounding air can be reduced, and it is convenient for the feeding of the materials.

[0023] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further introduced in detail below with reference to the accompanying drawings.

[0024] The present invention provides a raw material feeding station as shown in Figures 1 - 4 , which includes a support 1. A storage hopper 2 is arranged inside the support 1, and a detachable tonneau bag feeding port 12 is arranged at the top of the support 1. The tonneau bag feeding port 12 is communicated with the storage hopper 2. The bottom end of the storage hopper 2 is connected with a positive pressure airtight feeder 3, and an air inlet 4 is arranged on one side of the positive pressure airtight feeder 3, and a discharge port 5 is arranged on the other side;

[0025] A tonneau bag flapping structure is further arranged at the top of the support 1. The tonneau bag flapping structure includes two rotatable flappers 11 and a driving member for driving the two flappers 11 to swing reciprocally. The two flappers 11 are symmetrically distributed on both sides of the tonneau bag feeding port 12.

[0026] Specifically, a shaft rod 13 is fixed on one side of each of the two flappers 11, and bearing seats 14 are installed at both ends of the two shaft rods 13. The four bearing seats 14 are all fixed on the top of the support 1.

[0027] Furthermore, regarding the above-mentioned driving member, it includes two flapper cylinders 7 hinged inside the support 1. The top ends of the two flapper cylinders 7 are respectively hinged with curved connecting rods 9, and one ends of the two connecting rods 9 are respectively installed on the corresponding shaft rods 13.

[0028] During use, the air inlet 4 can be connected to an external Roots blower, the discharge port 5 can be connected to an external large-scale raw material bin, and then a tonneau bag is lifted above the tonneau bag feeding port 12 by a forklift or a crane. Subsequently, the materials in the tonneau bag start to flow into the storage hopper 2, and pass through the positive pressure airtight feeder 3. The raw materials are transported to the external large-scale raw material bin by wind through a conveying pipeline, so as to realize the rapid feeding and transportation of tonneau bag raw materials into the large-scale raw material bin;

[0029] When the raw materials in the bulk bag flow into the storage hopper 2, the shaft rod 13 can be driven to rotate through the cooperation of the flapping frame cylinder 7 and the connecting rod 9. Subsequently, the shaft rod 13 drives the two flapping frames 11 to swing reciprocally, continuously flapping the bulk bag, making the materials in the bulk bag slide down more easily and flow into the storage hopper 2. Moreover, it can reduce the residue of materials in the bulk bag and avoid waste of materials.

[0030] Meanwhile, in this embodiment, as Figure 1 and Figure 3 shown, a linkage is also connected between the two shaft rods 13. The linkage includes a gearbox 8 installed on the bracket 1. One end of each of the two shaft rods 13 extends into the gearbox 8 and is equipped with meshing gears.

[0031] When the flapping frame cylinder 7 drives the flapping frame 11 to flap the bulk bag, by using the meshing gears in the gearbox 8, the linkage of the two flapping frames 11 can be realized. And when driving the flapping frame 11 to flap the bulk bag, the two-layer cylinder thrust can be preferentially distributed. If the bulk bag is placed unevenly, it can effectively avoid the problem that one flapping frame 11 is overloaded with force and cannot perform the bag flapping work, leaving only one flapping frame 11 working and unable to quickly and effectively clean the materials in the bulk bag.

[0032] In addition, in an embodiment, as Figures 1 - 4 shown, a dust removal component is also provided on the bracket 1. The dust removal component includes a pulse dust collector 10 installed on the bracket 1, and the dust suction end of the pulse dust collector 10 is above the storage hopper 2.

[0033] An air escape chamber 6 is also provided on one side of the positive pressure airtight feeder 3, and the top of the air escape chamber 6 is connected with an exhaust pipe extending above the storage hopper 2.

[0034] During the feeding process, the pulse dust collector 10 forms a slightly negative pressure state above the storage hopper 2 through its dust suction end, sucking away the dust generated in the storage hopper 2 during the feeding process, so that there is no large amount of dust overflow during the feeding process, reducing the dust pollution of the surrounding air. And when the bulk bag is discharging, the gas in the positive pressure airtight feeder 3 will be compressed, and the gas escapes to above the storage hopper 2 through the air escape chamber 6 and the exhaust pipe and is sucked away by the pulse dust collector 10 together.

[0035] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
