Description

Technical Field

[0001] The utility model relates to the technical field of feeding mechanisms, in particular to a raw material feeding mechanism for a glue-making device. Background Art

[0002] During the production of corrugated cardboard, it is necessary to bond the face paper and multiple layers of base paper, so as to form a corrugated cardboard with a multi-layer structure. Therefore, during the production of corrugated cardboard, it is necessary to prepare glue for bonding corrugated cardboard and coat the glue on the face paper and the base paper. Therefore, it is necessary to produce glue with a glue-making device.

[0003] After retrieval, a patent with the publication number CN216093638U discloses a feeding device for the production of honeycomb cardboard glue, which includes an upper and lower connected feeding funnel and a funnel inner cover. A layer of filter screen is arranged between the feeding funnel and the funnel inner cover. A small dispersion mechanism is installed inside the funnel inner cover. The small dispersion mechanism consists of a speed-regulating motor, a rotating shaft connected to the speed-regulating motor, and a fan blade fixed at the end of the rotating shaft. A layer of filter screen cover is arranged outside the small dispersion mechanism. The whole feeding device is fixed on the reaction kettle by bolts. A stirring shaft and stirring blades connected to the stirring shaft are also installed inside the reaction kettle. During the production of honeycomb cardboard glue, when adding fillers to the semi-finished honeycomb cardboard glue, using the feeding device of this utility model can ensure that the fillers are added in small particle sizes, at an appropriate speed, and evenly, reduce equipment pollution, air pollution, and environmental sanitation pollution, improve the production speed, and ensure the quality of the finished honeycomb cardboard glue.

If the mesh holes of the filter screen cover are too large, the raw materials will directly fall into the reaction kettle after falling to the bottom of the filter screen cover. Therefore, the effect of evenly adding the glue-making raw materials is poor. Therefore, it is urgent for this field to improve the raw material feeding mechanism of the glue-making device to solve the defects of the existing technology. Summary of the Utility Model

When the moving block drives the pushing rod to rotate, the front end of the pushing rod in the shape of a hook guides the raw material at the edge of the filter plate, guiding the raw material at the edge of the filter plate to the position of the filter holes on the filter plate, preventing excessive accumulation of raw material at the edge of the filter plate.

[0017] 3. In the present utility model, through the setting of the fixed frame, one side of the fixed frame abuts against the inner side wall of the box body, which can clean the inner side wall of the box body and at the same time improve the connection strength of the stirring blades.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0031] Embodiment 1

[0032] Please refer to Figures 1-9 , a raw material feeding mechanism of a glue-making device, including a box body 1, a box cover 2 is fixedly installed on the upper part of the box body 1, a feed inlet 3 is penetrated and opened on the box cover 2, a discharge port 27 is arranged at the lower part of the box body 1, an electric control magnetic valve 4 for controlling the opening and closing of the discharge port 27 is arranged on the side of the discharge port 27, a vertical rotating shaft 5 located in the middle of the box body 1 is arranged in the box body 1, a driving motor 6 for driving the rotating shaft 5 to rotate is fixedly installed on the upper part of the box cover 2, a plurality of fixing frames 7 in a U shape and one side of which abuts against the inner side wall of the box body 1 are fixedly installed on the side of the rotating shaft 5, a plurality of stirring blades 8 are fixedly installed between one side of the fixing frame 7 and the side of the rotating shaft 5, a filter plate 9 sleeved on the side of the rotating shaft 5 and penetrated with a plurality of filter holes is arranged in the upper part of the box body 1, a push rod 10 and a rotatable rolling rod 11 are arranged on the side of the rotating shaft 5, and the sides of the push rod 10 and the rolling rod 11 abut against the upper surface of the filter plate 9.

[0033] Specific implementation in this embodiment: When feeding the box body 1 for glue making, the raw materials for glue making are introduced through the feed port 3. The raw materials in powder form fall on the filter plate 9. At the same time, the driving motor 6 is started. The output end of the driving motor 6 drives the rotating shaft 5 to rotate. When the rotating shaft 5 rotates, it drives the rolling rod 11 and the pushing rod 10 to rotate around the rotating shaft 5 as the axis. The pushing rod 10 pushes the piled raw materials on the filter plate 9 along the filter plate 9. The raw materials in powder form fall through the filter holes on the filter plate 9. At the same time, the rotatable rolling rod 11 crushes the powder on the filter plate 9 to prevent the raw materials in powder form from agglomerating and failing to fall through the filter holes. The raw materials are pushed by the pushing rod 10 and fall through the filter holes on the filter plate 9, improving the uniformity during the glue-making feeding process. They fall in powder form and evenly in the lower part of the box body 1, improving the glue-making efficiency of the glue-making device. While the rotating shaft 5 rotates, it drives the fixed frame 7 and the stirring blades 8 to rotate. The stirring blades 8 mix and stir the glue-making raw materials in the lower part of the box body 1. One side of the fixed frame 7 abuts against the inner side wall of the box body 1, which can clean the adhesives on the inner side wall of the box body 1. At the same time, the fixed frame 7 improves the fixing strength of the stirring blades 8 and extends the service life of the stirring blades 8. After the glue-making raw materials are mixed, the electromagnetic control valve 4 is opened, and the mixed colloid is discharged through the discharge port 27.

[0034] Embodiment Two

[0035] Please refer to Figure 4 、 Figure 5 、 Figure 7 and Figure 9 This embodiment includes the above-mentioned embodiment. Additionally, it further includes: A number of arc-shaped convex strips 12 are fixedly installed on the lower surface of the filter plate 9. The upper surface of the fixed frame 7 is attached to the lower surface of the filter plate 9 and is adapted to the arc-shaped convex strips 12. A first sliding opening 13 with a circular cross-section and a second sliding opening 14 with a polygonal cross-section are formed on the side surface of the rotating shaft 5. The filter plate 9 is sleeved on the first sliding opening 13. A moving block 15 with a thickness greater than that of the first sliding opening 13 is sleeved on the side surface of the second sliding opening 14. The pushing rod 10 is fixedly connected to the side surface of the moving block 15. The rolling rod 11 is rotatably connected to the side surface of the moving block 15. The end of the pushing rod 10 away from the rotating shaft 5 is hook-shaped. A baffle 16 located above the moving block 15 is fixedly connected to the side surface of the rotating shaft 5. A spring 17 sleeved on the side surface of the rotating shaft 5 is fixedly connected between the baffle 16 and the moving block 15. A number of limiting blocks 18 are fixedly connected to the side surface of the filter plate 9. A limiting groove 19 adapted to the limiting blocks 18 is formed on the upper side wall of the inner part of the box body 1.

[0036] Specific implementation method in this embodiment: The rotating shaft 5 drives the fixed frame 7 to rotate. When the fixed frame 7 rotates and contacts the arc-shaped convex strip 12, due to the setting of the arc-shaped convex strip 12, it will push the filter plate 9 upward. At this time, the limit block 18 slides in the limit groove 19, and the limit block 18 limits the filter plate 9, so that the filter plate 9 can only move up and down. The filter plate 9 moves upward at the position of the first sliding port 13. At this time, the filter plate 9 pushes the moving block 15 upward, and the moving block 15 squeezes the spring 17. The moving block 15 also drives the push rod 10 and the rolling rod 11 to move. When the fixed frame 7 disengages from the arc-shaped convex strip 12, the tension of the spring 17 pushes the moving block 15 downward. This process produces a vibrating effect on the filter plate 9, which has a vibrating effect on the raw materials on the filter plate 9, preventing the raw materials from blocking the filter holes on the filter plate 9. Moreover, the end of the push rod 10 away from the rotating shaft 5 is hook-shaped. When the moving block 15 drives the push rod 10 to rotate, the hook-shaped front end of the push rod 10 guides the raw materials at the edge of the filter plate 9 to the position of the filter holes on the filter plate 9, preventing too much raw materials from accumulating at the edge of the filter plate 9.

[0037] Embodiment III

[0038] Please refer to Figure 3 、 Figure 4 、 Figure 8 and Figure 9 This embodiment includes all the above embodiments. Among them, it further includes: A connecting rod 20 with a polygonal cross-section is fixedly connected to the output end of the driving motor 6. A connecting groove 21 adapted to the connecting rod 20 is opened at the upper end of the rotating shaft 5.

A bearing plate 24 is fixedly connected to the lower end of the rotating shaft 5. A plurality of support columns 25 are fixedly connected to the lower surface of the bearing plate 24. The lower part of the box body 1 is in the shape of a frustum of a cone with a wider upper part and a narrower lower part. The lower side surface of the fixed frame 7 abuts against the inner lower side wall of the box body 1 and the lower end of the fixed frame 7 is fixedly connected to the side surface of the support column 25. A rotating ring 26 is fixedly connected between the lower ends of the plurality of support columns 25. A rotating step 28 adapted to the rotating ring 26 is opened on the lower side wall of the box body 1.

[0039] Specific implementation method in this embodiment: The box cover 2 is connected to the upper part of the box body 1 through fasteners such as fastening bolts. When it is necessary to clean the inside of the box body 1 or maintain the components, the box cover 2 can be directly lifted, and the connecting rod 20 and the connecting groove 21 are disengaged, which is convenient for cleaning or maintaining the upper part of the filter plate 9. When the moving block 15 rotates, the balls 23 rotate in the embedding grooves 22, reducing the frictional resistance suffered by the moving block 15 during rotation. When the rotating shaft 5 rotates, the rotating ring 26 rotates at the position of the rotating step 28. After the colloid mixing and stirring is completed, the colloid flows to the discharge port 27 through the gaps between the support columns 25.

[0040] Among them, the driving motor 6 and the electro-control magnetic valve 4 mentioned above can both be purchased in the market. They belong to mature technologies and have been fully disclosed. Therefore, they will not be repeated in the specification.
