[0041] A packaging device for raw materials includes a frame, a pressing component and an inlet detection component, wherein:

[0042] The frame includes a lower frame 1, an upper frame 2 spanning above the lower frame 1, and a lifting assembly connected therebetween, wherein a conveyor belt 4 for material transmission runs in the lower frame 1;

[0043] The extrusion assembly comprises an upper extrusion assembly and a lower extrusion assembly which are arranged relatively to each other in the upper and lower directions. The upper extrusion assembly is connected to the upper frame 2 through a spring assembly 5, and the lower extrusion assembly is connected to the lower frame 1 through a connecting assembly 6, wherein: the upper extrusion assembly is located on the conveyor belt 4, and comprises a plurality of upper extrusion rollers, and the upper extrusion rollers are cylindrical rollers 7 or dumbbell-shaped rollers 8; the lower extrusion assembly is located inside the conveyor belt 4, and comprises a plurality of lower extrusion rollers, and the lower extrusion rollers are cylindrical rollers 7;

[0044] The entrance detection component includes an entrance bracket 9 spanning above the lower frame, an entrance guide structure arranged on the entrance bracket 9, and a grating detection structure.

[0045] In this embodiment, in order to solve the technical problems such as incomplete packaging, uneven product processing, inability to process the thinner parts on both sides or bag breakage due to excessive pressure, and lack of safety control measures during machine processing, a packaging device for raw materials is designed, which can greatly improve production efficiency and reduce production costs by replacing manual labor. Specifically: it includes a frame, an extrusion component, and an inlet detection component. The material is transmitted to between the upper extrusion component and the lower extrusion component through the conveyor belt 4, and the agglomerated material is pressed under the extrusion of the upper extrusion roller and the lower extrusion roller which are opposite to each other. The upper extrusion component is located above the conveyor belt 4, and includes a plurality of upper extrusion rollers. Taking the present embodiment as an example, five upper extrusion rollers are included. The upper extrusion rollers include cylindrical rollers 7 and / or dumbbell-shaped rollers 8. The third upper extrusion roller is selected for modification and is selected as the dumbbell-shaped roller 8, and the rest are selected as the cylindrical rollers 7. When only the third upper extrusion roller is modified, the material consumption can be reduced while achieving the same pressing effect. When the shapes of the five upper extrusion rollers are modified at the same time, the uniformity and looseness of the material after pressing are improved by about 5% compared with only modifying one upper extrusion roller.

[0046] In addition, the upper frame 2 and the lower frame 1 are connected by a lifting assembly, and the distance between the upper frame 2 and the lower frame 1 can be adjusted according to needs, and then the distance between the upper extrusion roller and the lower extrusion roller can be adjusted to adapt to the packaging processing of materials of various specifications; the upper extrusion assembly is connected to the upper frame 2 through the spring assembly 5, and the spring assembly 5 can provide a certain elastic stroke. During the extrusion process, the upper extrusion assembly can move up and down relative to the upper frame, so that the extrusion process is not affected by the shape of the material agglomerates, thereby ensuring the extrusion effect of the material and achieving a good packaging effect. It also helps to reduce the wear of the agglomerated materials on the upper extrusion roller, the lower extrusion roller and the conveyor belt.

[0047] Furthermore, in this embodiment, it can also be considered that the lifting assembly includes a plurality of synchronous lifting cylinders 3, the upper ends of the synchronous lifting cylinders 3 are connected to the upper frame 2, and the lower ends are connected to the lower frame 1.

[0048] Furthermore, in the present embodiment, it can be considered that the inlet bracket 9 is located on the inlet side of the upper frame 2, and the inlet guide structure is an eight-shaped guide rod 10 relatively arranged on the inlet bracket 9. The material on the conveyor belt can be guided in a standardized manner when passing through the eight-shaped guide rod 10, so that the material enters between the upper extrusion roller and the lower extrusion roller in an ideal arrangement manner, thereby achieving a standardized and uniform bag pressing effect.

[0049] Furthermore, in the present embodiment, it can also be considered that the grating detection structure is an entrance safety grating 11 relatively arranged on the entrance bracket 9. Adding the entrance safety grating can prevent people from approaching the entrance, and the operation of the package pressing device is stopped in time after sensing that people are approaching the entrance, thereby reducing casualties.

[0050] Furthermore, in the present embodiment, it can also be considered that the upper extrusion assembly includes two upper assembly rails 12 arranged in parallel and an upper extrusion roller rotatably installed between the two upper assembly rails 12, and the two ends of the roller shaft of the upper extrusion roller are respectively installed on the two upper assembly rails 12 through an upper roller shaft assembly structure 13, and the upper roller shaft assembly structure 13 is slidably installed on the upper assembly rails 12 and locked with each other through a locking structure 14.

[0051] Furthermore, in this embodiment, it can be considered that the upper end of the upper assembly track 12 is connected to the upper frame 2 through a spring assembly, and the lower end is provided with a T-shaped slideway with both ends open along its length direction, and the upper roller shaft assembly structure 13 includes a bearing seat and a T-shaped slider fixed on the outside of the bearing seat and slidingly adapted to the T-shaped slideway. The upper extrusion roller is perpendicular to the upper assembly track 12, and the T-shaped slider and the T-shaped slideway slidingly adapted to the slideway can adjust the installation position of each upper roller shaft assembly structure 13 according to needs, and then adjust the installation position of the upper extrusion roller relative to the upper assembly track 12, and flexibly install the upper extrusion rollers with appropriate number, appropriate spacing, and appropriate position according to needs.

[0052] Furthermore, in this embodiment, it can also be considered that the locking structure 14 can be but not limited to a bolt assembly, and a plurality of screw holes are evenly opened on the side wall of the upper assembly rail 12 to fix the upper roller shaft assembly structure 13 at a suitable position of the upper assembly rail 12 as required.

[0053] Furthermore, in the present embodiment, it can also be considered that both ends of the roller shaft of the upper extrusion roller are respectively rotatably installed in the bearing seats, and a driving sprocket is installed on the roller shaft of each upper extrusion roller, which is connected to the motor sprocket on the motor shaft of the driving motor through a chain ring, so as to achieve the effect of a driving motor driving each upper extrusion roller to rotate synchronously, and the driving motor can control the synchronous rotation of multiple upper extrusion rollers, thereby extruding the material.

[0054] Furthermore, in the present embodiment, it can also be considered that the dumbbell-shaped roller 8 includes a small-diameter cylindrical roller section located in the middle, large-diameter cylindrical roller sections located on both sides, and a frustum roller section transitionally connected between the large-diameter cylindrical roller section and the small-diameter cylindrical roller section, and the diameter of the large-diameter cylindrical roller section is the same as the diameter of the cylindrical roller.

[0055] By optimizing the shape of the upper extrusion roller, adding a dumbbell-shaped roller to the cylindrical roller, the dumbbell-shaped roller has a shape of "big at both ends and small in the middle", which can make the pressure more uniform according to the shape characteristics of the packaging bag. After processing, the product is evenly dispersed and not easy to break. The uniformity is improved by 20% and there is no obvious block material, and the bag breakage rate is reduced by 80%. In addition, the number and position of the rollers are also optimized. Since the modification at the entrance is more prone to wear and tear, and the modification at the exit has a higher bag breakage rate, it is preferred to select the third roller for modification to achieve the same bag pressing effect while reducing material consumption; if the shapes of the five rollers are modified at the same time, the uniformity and looseness of the material after bag pressing will be improved by about 5% compared with modifying only one roller.

[0056] Furthermore, in this embodiment, it can also be considered that the cylindrical roller 7 and the dumbbell-shaped roller 8 in the upper extrusion assembly are arranged in an interlaced manner.

[0057] Furthermore, in the present embodiment, it can also be considered that the lower extrusion assembly includes two lower assembly rails 15 arranged in parallel and a lower extrusion roller installed between the two lower assembly rails 15, and the two ends of the roller shaft of the lower extrusion roller are respectively installed on the two lower assembly rails 15 through the lower roller shaft assembly structure 16, and the lower roller shaft assembly structure 16 is slidably installed on the lower assembly rails 15 and locked with each other through the locking structure 14.

[0058] Furthermore, in this embodiment, it can be considered that the lower end of the lower assembly track 15 is connected to the lower frame 1 through the connecting component 6, and the upper end is provided with a T-shaped slideway with both ends open along its length direction, and the lower roller shaft assembly structure 16 includes a bearing seat and a T-shaped slider fixed on the outer side of the bearing seat and slidingly adapted to the T-shaped slideway. The lower extrusion roller is perpendicular to the lower assembly track 15, and the T-shaped slider and the T-shaped slideway slidingly adapted to the slideway can adjust the installation position of each lower roller shaft assembly structure 16 according to the needs, and then adjust the installation position of the lower extrusion roller relative to the lower assembly track 15, and flexibly install the lower extrusion rollers with appropriate number, appropriate spacing, and appropriate position according to the needs.

[0059] Furthermore, in this embodiment, it can also be considered that the locking structure 14 can be but not limited to a bolt assembly, and a plurality of screw holes are evenly opened on the side wall of the lower assembly track 15 to fix the lower roller shaft assembly structure 16 at a suitable position of the lower assembly track 15 as required.

[0060] Furthermore, in this embodiment, it can be considered that the roller shaft of the lower extrusion roller and the lower roller shaft assembly structure 16 can be fixedly connected or rotatably connected. The preferred method is to fix the connection, and the purpose of the setting is to provide support for the upper extrusion roller. When the connection is rotatably connected, a driving motor can be provided to drive the lower roller shaft assembly structure 16.
