[0002] Horizontal packaging machines are widely used in many industries, including food, cosmetics, pharmaceuticals, daily chemical products, agricultural materials, and industrial products. Horizontal packaging machines adopt a fully automatic horizontal bag making, filling, and sealing process, hence the name.

[0022] The top of material containing bucket 1 is fixedly connected with mounting plate 2, the bottom of material containing bucket 1 is fixedly connected with conical feeding groove 4, and the conical design facilitates downward conveying of material. The inside of conical feeding groove 4 is fixedly connected with first support ring 7, and the bottom of conical feeding groove 4 is fixedly connected with material filling pipe 5. The electromagnetic valve 6 is fixedly installed on the material filling pipe 5. The electromagnetic valve 6 and the control terminal of factory assembly line are wiredly electrically connected. The control of the electromagnetic valve 6 by the control terminal can realize automatic filling.

[0023] The high pressure branch air cylinder 8 is located inside the conical feeding groove 4. The high pressure branch air cylinder 8 is placed on the top of the first support ring 7 through the second support ring 9. When the high pressure branch air cylinder 8 sprays high pressure air through the material loosening air pipe 13, a reverse pushing force is applied to the high pressure branch air cylinder 8, so that the bottom of the second support ring 9 tightly abuts against the top of the first support ring 7, thereby making the high pressure branch air cylinder 8 more convenient to place and take out. The top inside of the second support ring 9 is designed to be downwardly inclined, and the inclined design reduces the blocking of the material inside the conical feeding groove 4.

[0024] The material loosening air pipe 13 is designed to be upwardly inclined, and the material loosening air pipe 13 is in communication with the inside of the high-pressure branch air cylinder 8, and the air in the high-pressure branch air cylinder 8 is blown to the upper side around the high-pressure branch air cylinder 8 through the material loosening air pipe 13, the air blown out through the material loosening air pipe 13 pushes the material at the central position in the conical feeding groove 4 to move upward, and with the upward movement of the material at the central position in the conical feeding groove 4, the extrusion of the material at the central position in the conical feeding groove 4 to the peripheral material is reduced, thereby reducing the friction between the materials.

[0025] One end of the conveying pipe 3 is fixedly installed at the top end of the air cylinder connecting part 11, and the other end of the conveying pipe 3 is installed to the output end of the high-pressure fan, and the fan conveys the air to the inside of the high-pressure branch air cylinder 8 through the conveying pipe 3.

[0026] Working principle: in the use process, first, the high-pressure branch air cylinder 8 is placed in the conical feeding groove 4 by external force, and the second supporting ring 9 is placed at the top end of the first supporting ring 7, then the top end of the air cylinder connecting part 11 is connected to one end of the conveying pipe 3 away from the high-pressure fan, then the air cylinder connecting part 11 is threadedly connected to the top end of the high-pressure branch air cylinder 8 by external force, then the material is poured into the inside of the material containing barrel 1, and when packaging, the external high-pressure fan is started, the fan conveys the air to the inside of the high-pressure branch air cylinder 8 through the conveying pipe 3, the air in the high-pressure branch air cylinder 8 is blown to the upper side around the high-pressure branch air cylinder 8 through the material loosening air pipe 13, the air blown out through the material loosening air pipe 13 pushes the material at the central position in the conical feeding groove 4 to move upward, and with the upward movement of the material at the central position in the conical feeding groove 4, the extrusion of the material at the central position in the conical feeding groove 4 to the peripheral material is reduced, thereby reducing the friction between the materials, and when the high-pressure branch air cylinder 8 sprays high-pressure air through the material loosening air pipe 13, a reverse pushing force is applied to the high-pressure branch air cylinder 8, so that the bottom end of the second supporting ring 9 tightly abuts against the top end of the first supporting ring 7, the opening and closing of the electromagnetic valve 6 is controlled through the control terminal of the assembly line to carry out the bagging operation of the material, and when the electromagnetic valve 6 is opened, the material in the conical feeding groove 4 is discharged through the material filling pipe 5, and since the air flow discharged through the material loosening air pipe 13 blows the material to move and reduces the friction between the materials, the material is more smoothly discharged through the material filling pipe 5, so as to reduce the probability of the material filling pipe 5 being blocked.
