[0002] Automatic filling machines can quantitatively fill granular materials, powder materials, bar materials, etc. The speed can be adjusted to fast, medium or slow. The filling speed is faster, which greatly improves the loading speed of the product. Automatic filling machines usually use bags to hold materials.

[0003] At present, when using bags to hold materials, in order to prevent the materials from falling outside the bags, the bag mouth usually needs to be opened. Generally, workers support the bag mouth and then receive the materials. When the material filling speed is slow, the workers need to always support the bag mouth, which may easily cause soreness in the workers' arms. At the same time, dust in the materials is easy to diffuse, which may harm the health of the workers. Based on this, an opening and receiving material structure of an automatic filling machine is proposed to solve the above problems. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] like Figures 1 to 3As shown, the bagging material receiving structure of the automatic filling machine of this embodiment includes a filling machine body 1. The filling machine body can automatically control the weight of the falling material to realize equal batch weighing of the material. The filling machine body 1 is installed on the bottom plate 2. A discharge pipe 3 is arranged at the lower end of the filling machine body 1. The discharge pipe 3 is used to discharge the material into the pocket to realize the filling of the material. Four fixing rods 4 are installed in a rectangular array on the upper end of the bottom plate 2 below the discharge pipe 3. The upper ends of the fixing rods 4 are all inclinedly installed with fixing plates 5. The installation angle of the fixing plates 5 is 45 degrees. One end of the fixing plates 5 is installed with an electric telescopic rod 6. The output ends of the movable telescopic rods 6 respectively pass through the fixed plates 5, and the output ends of the electric telescopic rods 6 are all equipped with pull plates 7. The pull plates 7 are driven to move toward each other by controlling the shortening of the electric telescopic rods 6. The four pull plates 7 can support the bag openings of the pockets that need to be packaged, so as to keep the bag openings open. The pull plates 7 are symmetrically distributed along the diagonal lines of a rectangle. A placement plate 8 is movably installed under the four pull plates 7. The placement plate 8 is used to place the pockets to be packaged. A dust collection component is installed on the upper ends of the pull plates 7. The dust collection component is used to extract dust that diffuses to the outside during packaging to prevent dust from affecting the physical and mental health of the staff.

[0023] Specifically, a contact block 10 is installed at one end of the pull plate 7 below the electric telescopic rod 6. A plurality of grooves 11 are arranged on the surface of one end of the contact block 10. The contact block 10 is made of soft rubber material. The design of the groove 11 facilitates contact with the pocket opening without sliding with the pocket, thereby effectively preventing the pull plate 7 from causing invalid pulling on the pocket.

[0024] Furthermore, the placement plate 8 is installed on the surface of four fixed rods 4 through through holes, and elastic springs 12 are installed on the surface of the fixed rods 4 between the lower end of the placement plate 8 and the upper end of the bottom plate 2. When the placement plate 8 is in the initial state, the elastic springs 12 are used to support the placement plate 8, so as to reduce the distance between the bottom end of the pocket and the discharge pipe 3 during the initial packaging, so as to avoid the powdery material from being diffused due to the material falling from too high a height. As the material inside the pocket on the placement plate 8 increases, the placement plate 8 compresses the elastic springs 12 to keep the material at a certain drop height.

[0025] Furthermore, mounting plates 13 are installed on both sides of the front end of the base plate 2, and foot switches 14 are installed on the upper ends of the mounting plates 13. The two foot switches 14 are used to control the four electric telescopic rods 6 to extend and retract at the same time, which is convenient for controlling the electric telescopic rods 6 and is convenient for workers to use.

[0026] Furthermore, the dust collection component includes a dust hood 901, a connecting pipe 902, an exhaust fan 903, a connecting box 904 and a dust bag 905. The dust hood 901 is installed on the upper end of the pull plate 7, and a connecting pipe 902 is installed at one end of the dust hood 901. The exhaust fan 903 is installed on the upper end of the bottom plate 2 behind the discharge pipe 3. A connecting box 904 is installed at the input end of the exhaust fan 903. Four connecting pipes 902 are respectively connected to the connecting box 904. A dust bag 905 is detachably installed at the output end of the exhaust fan 903. By controlling the exhaust fan 903 to start, the exhaust fan 903 generates suction in the dust hood 901 through the connecting box 904 and the connecting pipe 902, so as to extract the dust diffused to the outside of the pocket, and the gas that extracts the dust enters the dust bag 905, so that the dust remains in the dust bag 905, and the gas is discharged through the surface of the dust bag 905, so as to realize the collection of dust.

[0027] Furthermore, the dust bag 905 is installed at the output end of the vacuum pump 903 by means of a strap, and the dust bag 905 can be removed from the output end of the vacuum pump 903 to facilitate cleaning of the dust inside the dust bag 905 .

[0028] The method of using the present embodiment is as follows: when using the automatic packaging machine to package materials, first add the materials into the automatic packaging machine, then open the mouth of the pocket to be packaged, and then sleeve the mouth of the pocket on the outside of the four pull plates 7 so that the bottom of the pocket is located on the upper end of the placement plate 8, and then control the electric telescopic rod 6 to shorten through the foot switch 14, and the four pull plates 7 move toward each other, and the contact block 10 on one side of the pull plate 7 generates a pulling force on the mouth of the pocket, so that the mouth of the pocket is in an open state, and then control the packaging body 1 to drop the materials, and the materials fall into the pocket through the discharge pipe 3. As the amount of materials in the pocket increases, the placement plate 8 The elastic spring 12 is compressed to keep the height of the material falling consistent. During the packaging process, the vacuum fan 903 generates suction in the dust hood 901 through the connecting box 904 and the connecting pipe 902, so as to extract the dust diffused to the outside of the pocket. The gas used to extract the dust enters the dust bag 905, so that the dust remains in the dust bag 905. The gas is discharged through the surface of the dust bag 905 to collect the dust. After the packaging is completed, the electric telescopic rod 6 is extended by the foot switch 14, so that the contact block 10 no longer contacts the pocket, and the pocket and material after the packaging are completed can be removed.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
