Abstract
Description
Technical Field
[0001] The utility model relates to a raw material mixing device for producing degradable packaging bags, belonging to the technical field of packaging bag production. Background Art
[0002] Packaging bags are bags used to package various items, making them easy to transport and store during production and distribution, and are widely used in daily life and industrial production. Degradable packaging bags are generally made from polymer materials such as PLA, PHAS, PBA, and PBS. Tests have shown that degradable plastics generally begin to thin and lose weight after three months of exposure to the natural environment. Along with a decrease in strength, the bags gradually break into pieces, completing a green cycle of "coming from nature and returning to nature." This fully complies with the development requirements of a green economy and is therefore gradually being widely used in various fields. During the production of degradable packaging bags, several different raw materials need to be mixed with liquid plasticizers, colloidal adhesives, and other agents in a raw material mixing device for mixing.
[0003] Although the existing raw material mixing device plays a certain role in the daily mixing of raw materials for packaging bag production, it has exposed many defects during the actual production scene application process. The single-direction rotation stirring method of its stirring shaft has become one of the key factors affecting the mixing effect. When the stirring shaft continues to rotate in a fixed direction, the raw materials inside will gradually form a regular vortex phenomenon. Driven by the strong vortex, the raw materials almost only move around the stirring shaft in a circular manner. There is a lack of sufficient and effective mutual collision and interlacing between the raw material particles, making it difficult to achieve all-round and deep uniform mixing. This directly leads to the final mixing effect being not good enough, and thus the use effect of the raw material mixing device is not good enough.
[0004] Furthermore, there are also inconsistencies in the raw material unloading process. Typically, for convenience and ease of use, workers often adopt a crude method of dumping all the raw materials into the mixing device at once. As a result, at the initial stage of the mixing operation, the interior of the device is instantly filled with a large amount of raw materials. The excessive accumulation of raw materials creates significant resistance for the agitator shaft during operation, limiting the range of raw materials that can be driven for mixing with each rotation. This significantly reduces the mixing speed, leading to lower efficiency for the raw material mixing device. Utility Model Content

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0026] Example 1
[0027] The embodiment of the utility model provides a raw material mixing device for producing degradable packaging bags.
[0028] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4, including a frame 1, a frame slot 2 opened inside the frame 1 can be used for loading raw materials, a frame slot 2 is opened in the middle of the frame 1, and silos 3 are opened on both sides of the upper end of the frame slot 2, and the silos 3 are used to place raw materials, a discharge pipe 4 is fixed in the middle of the lower end of the frame 1, and the discharge pipe 4 and the control valve 5 control the discharge, and a control valve 5 is provided in the middle of the discharge pipe 4, and brackets 17 are fixed on both sides of the lower end of the frame 1; a driving motor 6 is fixed to the upper end of the frame 1, and a fixed rod 7 is fixed to the driving end of the driving motor 6, and a connecting structure is provided on the fixed rod 7, and the connecting structure includes a second stirring frame 13 and an active bevel gear 8, the active bevel gear 8 is meshedly connected with a linkage bevel gear 9, and the linkage bevel gear 9 is meshedly connected with a driven bevel gear 10, a fixed frame 11 is fixed in the middle of the driven bevel gear 10, and a first stirring frame 12 is fixed at the other end of the fixed frame 11.
[0029] Please refer again Figure 1 、 Figure 2 、 Figure 3 and Figure 4 It is worth mentioning that the middle part of the active bevel gear 8 is fixed on the upper side of the fixed rod 7, the active bevel gear 8 is meshed with one side of the linkage bevel gear 9, the outer surface of the linkage bevel gear 9 is rotatably connected to the inner wall of the frame body 1, and the other side of the linkage bevel gear 9 is meshed with the driven bevel gear 10, and the outer surface of the driven bevel gear 10 is rotatably connected to the inner wall of the frame body 1. The upper end of the fixed frame 11 is fixed to the middle part of the driven bevel gear 10, and the lower end of the fixed frame 11 is fixed to the middle part of the first stirring frame 12. The middle parts of the driven bevel gear 10, the fixed frame 11 and the first stirring frame 12 are all hollow. The fixed rod 7 passes through the middle parts of the driven bevel gear 10, the fixed frame 11 and the first stirring frame 12 in sequence. The middle part of the second stirring frame 13 is fixed to the lower end of the fixed rod 7. The first stirring frame 12 and the second stirring frame 13 are vertically distributed. The vertical sections of the first stirring frame 12 and the second stirring frame 13 are both U-shaped, and the first stirring frame 12 is arranged inside the second stirring frame 13.
[0030] During use, the present invention rotates the fixed rod 7 through the drive motor 6, causing the second stirring frame 13, which is fixed to the lower end of the fixed rod 7, to rotate. Simultaneously, the driving bevel gear 8, affixed to the upper side of the fixed rod 7, also begins rotating. As the driving bevel gear 8 rotates, it engages with the interlocking bevel gear 9, driving the interlocking bevel gear 9 in a corresponding rotational motion. The interlocking bevel gear 9, in turn, engages with the driven bevel gear 10, causing the rotating interlocking bevel gear 9 to rotate in the opposite direction. The driven bevel gear 10, via the fixed frame 11 to which it is attached, drives the first stirring frame 12 in the opposite direction. This allows the first stirring frame 12 and the second stirring frame 13 to achieve counter-rotating, coordinated operation. Working together, they provide comprehensive, multi-angle mixing of the raw materials within the frame trough 2. This unique design achieves thorough mixing, effectively avoiding the drawback of incomplete mixing caused by single-direction stirring, thereby enhancing the performance of the raw material mixing device.
[0031] Example 2
[0032] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , based on the embodiment 1, a quantitative feeding function is added;
[0033] Please refer again Figure 1 、 Figure 2 、 Figure 3 and Figure 4 It is worth mentioning that a blocking rack 14 is fixed to the upper end of the second stirring rack 13, a groove 15 is provided in the middle of the blocking rack 14, and feed ports 16 are provided on both sides of the upper end of the groove 15. The two feed ports 16 are arranged below the discharge ports of the two silos 3, and the first stirring rack 12 is arranged inside the blocking rack 14.
[0034] When the utility model is in use: the fixed rod 7 is driven by the driving motor 6 to rotate, and the rotating fixed rod 7 drives the second stirring frame 13 fixed at the lower end to rotate, and the blocking frame 14 fixed at the upper end of the second stirring frame 13 will rotate synchronously under the drive of the second stirring frame 13. At this time, the rotating blocking frame 14 realizes the quantitative discharge of the raw materials in the silo 3 by means of the two feed ports 16 opened by itself. Specifically, only when the feed port 16 rotates to a position corresponding to the discharge port of the silo 3, the raw materials in the silo 3 can fall smoothly into the blocking frame 14, and under the guiding effect of the inclined surface of the groove 15 of the blocking frame 14, accurately fall into the middle area of the frame groove 2. Once the feed port 16 rotates away from the discharge port of the silo 3, the raw materials will be blocked by the upper surface of the blocking frame 14, thereby stopping the discharge. Through this ingenious design and operation mode, the effect of quantitative feeding is successfully achieved, effectively avoiding the problem of slowing down the mixing speed of raw materials due to the one-time large-scale entry of raw materials, thereby achieving the effect of improving the working efficiency of the raw material mixing device.
