DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The present utility model will be further described below in conjunction with specific embodiments. The illustrative embodiments and explanations of the present utility model are used to explain the present utility model, but do not limit the present utility model.

[0024] Embodiment 1

[0025] The automatic metering and packaging machine for the finished product of magnesium sulfate heptahydrate, such as Figure 1 , Figure 2 and Figure 3As shown in the figure, it includes a support base 1, a packaging machine 2, a discharge pipe 3, a blanking wheel 4, a first motor 5, a guide rod 6, a connecting plate 7, a filter screen 8, a spring 9, a first rotating shaft 10, a cam 11 and a second motor 12. The upper part of the support base 1 is connected with the packaging machine 2. The support base 1 is made of stainless steel, which is convenient for the support base 1 to support the packaging machine 2. The lower side of the packaging machine 2 is fixedly connected with the discharge pipe 3. The metered magnesium sulfate heptahydrate finished product can flow out from the discharge pipe 3. The packaging machine 2 is rotatably connected with the blanking wheel 4, and the blanking wheel 4 can quantitatively discharge the magnesium sulfate heptahydrate finished product. The first motor 5 is installed on the left side of the packaging machine 2, and the blanking wheel 4 is connected with the first motor 5 through a coupling. Two guide rods 6 are fixedly connected to the upper parts on the left and right sides of the packaging machine 2. A connecting plate 7 is slidably connected to the two guide rods 6 on the same side. A filter screen 8 is fixedly connected between the connecting plates 7. Springs 9 are wound around the four guide rods 6, and the two ends of the springs 9 are respectively connected to the guide rods 6 and the connecting plate 7. The second motor 12 is installed on the right side of the packaging machine 2. The packaging machine 2 is rotatably connected with the first rotating shaft 10, and the first rotating shaft 10 is connected with the output shaft of the second motor 12. Symmetrically fixed on the first rotating shaft 10 are cams 11.

[0026] Since the magnesium sulfate heptahydrate finished product will agglomerate due to absorbing the humidity in the environment, when the agglomerated magnesium sulfate heptahydrate finished product is being packaged, the gaps between the block sizes will cause inaccurate feeding of the material, and the quality of the packaged magnesium sulfate heptahydrate finished product is poor. First, manually pour the magnesium sulfate heptahydrate finished product onto the filter screen 8, and then manually control the second motor 12 to start, which then drives the first rotating shaft 10 to rotate, causing the cam 11 to rotate. When the cam 11 rotates to squeeze the connecting plate 7 to move upward on the guide rod 6, the connecting plate 7 drives the filter screen 8 to move upward. At this time, the spring 9 is compressed. When the cam 11 rotates away from the connecting plate 7, the spring 9 resets to drive the connecting plate 7 to move downward on the guide rod 6, and then the filter screen 8 moves up and down back and forth to generate vibration, so that the magnesium sulfate heptahydrate finished product with better quality after dispersion falls onto the blanking wheel 4. When the blanking wheel 4 is filled with the magnesium sulfate heptahydrate finished product, control the first motor 5 to start, which then drives the blanking wheel 4 to rotate. Subsequently, manually pour a quantitative amount of the magnesium sulfate heptahydrate finished product into the packaging machine 2, and the metered magnesium sulfate heptahydrate finished product flows out from the discharge pipe 3. After packaging the magnesium sulfate heptahydrate finished product, manually turn off the first motor 5 and the second motor 12, thereby achieving the improvement of the packaging quality of the magnesium sulfate heptahydrate finished product.

[0027] Embodiment 2

[0028] On the basis of Embodiment 1, such as Figure 1 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7As shown in the figure, it also includes a cover plate 13, a blanking cylinder 14, a feeding plate 15, a pulley assembly 16, a second rotating shaft 17 and a material guiding plate 18. A cover plate 13 is fixedly connected to the upper part of the packaging machine 2, and a blanking cylinder 14 is fixedly connected to the cover plate 13. A feeding plate 15 is rotatably connected to the middle of the blanking cylinder 14. The feeding plate 15 is used for conveying materials. A pulley assembly 16 is connected between the left part of the feeding plate 15 and the left part of the first rotating shaft 10. The pulley assembly 16 includes two pulleys and a flat belt. A pulley is respectively connected to the left part of the feeding plate 15 and the left part of the first rotating shaft 10, and a flat belt is wound between the two pulleys. The feeding plate 15 can be driven to rotate through the pulley assembly 16, and then the finished product of magnesium sulfate heptahydrate can be moved and conveyed. Second rotating shafts 17 are symmetrically and rotatably connected to the blanking cylinder 14, and a material guiding plate 18 is connected to the second rotating shafts 17. The material guiding plate 18 is used for guiding the materials to be dispersed.

[0029] In order to prevent too much magnesium sulfate heptahydrate finished product from accumulating on the filter screen 8, which may cause inconvenience in controlling the measurement during the packaging of the magnesium sulfate heptahydrate finished product, the following operations can be carried out. First, manually pour the magnesium sulfate heptahydrate finished product into the blanking cylinder 14. When the second motor 12 is started, the feeding plate 15 can be driven to rotate through the rotation of the pulley assembly 16, so that the magnesium sulfate heptahydrate finished product moves to the left along with the feeding plate 15. Thus, the magnesium sulfate heptahydrate finished product is dispersed through the feeding plate 15, and the magnesium sulfate heptahydrate finished product is conveyed through the blanking cylinder 14. And the operator can also rotate the second rotating shaft 17 to make the inclination angle of the material guiding plate 18 different. The magnesium sulfate heptahydrate finished product passes through the blanking cylinder 14 and is conveyed to the filter screen 8 through the material guiding plate 18, so as to realize uniform dispersion of the materials and prevent too much magnesium sulfate heptahydrate finished product from accumulating on the filter screen.

[0030] As Figure 1 、 Figure 6 and Figure 7 shown in the figure, it also includes a torsion spring 19, a mounting plate 20 and a top plate 21. A torsion spring 19 is wound around the second rotating shaft 17, and the two ends of the torsion spring 19 are respectively connected to the second rotating shaft 17 and the blanking cylinder 14. Mounting plates 20 are fixedly connected to the left and right parts of the second rotating shaft 17, and top plates 21 are symmetrically fixedly connected to the connecting plate 7. The top plates 21 are in extrusion fit with the mounting plates 20.

[0031] The rotation position of the material guiding plate 18 can determine the dispersion degree of the magnesium sulfate heptahydrate finished product on the filter screen 8. Therefore, when discharging the magnesium sulfate heptahydrate finished product, the upward movement of the connecting plate 7 will drive the top plate 21 to move upward and squeeze the mounting plate 20, so that the second rotating shaft 17 rotates, thus driving the material guiding plate 18 to rotate. At the same time, the torsion spring 19 deforms. When the connecting plate 7 moves downward and drives the top plate 21 to disengage from the mounting plate 20, the torsion spring 19 resets and drives the material guiding plate 18 to rotate. Thus, the material guiding plate 18 rotates intermittently, making it more conducive to dispersing the magnesium sulfate heptahydrate finished product more evenly.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
