Description

Technical Field

[0001] The invention belongs to the technical field of mixing equipment, and in particular relates to a mixing equipment for raw materials for producing degradable packaging containers. Background Art

[0002] With the strengthening of environmental awareness, degradable packaging is increasingly widely used in people's lives due to its partially or completely degradable characteristics compared to plastic packaging, such as tableware, packaging bags, etc. In the food and catering industry, degradable tableware is mostly made of starch and straw powder mixed with auxiliary materials such as gelatin and bio-polyester, which are finally mixed with water to form a fluid. After drying and cutting, or directly injected into the mold for hot compression molding, it forms a packaging container.

[0003] At present, before hot compression molding, the key is to fully mix the powder, granular and liquid raw materials with each other to meet the needs of subsequent compression molding. At present, most of the mixing methods are to directly inject the concentrated raw materials into the mixing equipment for mixing. However, due to the surface tension between the powder, granular and liquid raw materials, agglomeration of the powder, granular raw materials and liquid is likely to occur during the mixing process, which in turn leads to defects in the subsequent compression molded products. To avoid this phenomenon, most of the solutions are to extend the stirring time, but this will extend the processing time and some agglomerated materials will still be difficult to disperse.

DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0029] Example 1: Figure 1-7 As shown, a raw material mixing device for producing a degradable packaging container comprises a tank body 1 and a control panel. The tank body 1 is horizontally arranged, and a feed port 11 and a discharge port 12 are respectively arranged at the upper and lower ends of one side of the tank body 1. A first stirring mechanism is arranged inside the tank body 1, and a second stirring mechanism is arranged on the upper side of the outer side of the tank body 1.

[0030] The second stirring mechanism includes a feeding barrel 3, a transmission assembly and a plurality of material distribution assemblies. The feeding barrel 3 is arranged on the upper side of the tank body 1 and is integrally connected thereto. The transmission assembly is arranged inside the feeding barrel 3. The plurality of material distribution assemblies are equidistantly arranged on the upper side of the feeding barrel 3. The feeding barrel 3 is provided with a powder inlet on the starting side of the transmission assembly.

[0031] The material distribution component includes a storage barrel 2, a connecting nozzle 31 and a distributor. The connecting nozzle 31 is integrally formed with the storage barrel and is connected to the feeding barrel 3. The distributor is arranged in the connecting nozzle 31 and is connected and matched with the conveying component.

[0032] The distributor includes a round wheel 4, an end head 41 and a push rod 42. The connecting nozzle 31 is provided with a round cavity connecting the storage barrel and the feeding barrel 3. The round wheel 4 is rotatably sealed in the round cavity. The connecting nozzle 31 is also provided with a side through cavity 43 connected to the inner wall of the front and rear ends of the round cavity. The end head 41 is located in the side through cavity 43 and is concentrically connected to the round wheel 4. The side through cavity 43 is connected to the feeding barrel 3. There are several push rods 42 connected to the end head 41. The push rods 42 extend into the feeding barrel 3. Several distribution chambers 44 are evenly provided on the side of the round wheel 4. Several powder distribution ports 45 that are interconnected are evenly provided between the storage barrel and the tank body 1.

[0033] When mixing the raw materials, the liquid raw material is injected into the tank body 1 through the feed port 11, and the other granular or powder raw materials are respectively input into the feed barrel 3 through the dividing component and the powder inlet and then into the tank body 1 for mixing. When the main powder raw material such as corn starch is input into the feed barrel 3, the conveying component is turned on by the control panel, and the powder raw material in the feed barrel 3 is transported and moved. When the conveying component passes through the dividing component, it will push the push rod 42 in the divider, and the dividing chamber 44 opened on the round wheel 4 will quantitatively transport the other mixed granular raw materials stored in the storage barrel in batches until the round wheel 4 is driven to rotate under the pushing action of the push rod 42, so that the other granular raw materials fall into the powder raw material. With the conveying of the powder raw material by the conveying component and the vibration of the equipment operation, a certain preliminary mixing and position change will occur between the powder and the particles. At the same time, the speed and time of the granular raw material being put into the powder raw material are matched, that is, the granular raw material is only put when the powder raw material is conveyed, which further avoids the accumulation caused by the continuous introduction of granular raw materials and affects the subsequent mixing uniformity.

[0034] The powder distribution port 45 opened between the storage barrel and the tank body 1 will guide the powder raw material or the granular raw material into the tank body 1 and drop it into the liquid raw material inside during the powder raw material conveying process, and finally mix and stir it through the first stirring mechanism. This mixing method can disperse the feeding position and area of ​​the powder and granular raw materials when mixing the raw materials, reduce the accumulation of a large amount of raw materials when feeding at a single position, resulting in more time required for mixing to achieve a uniform effect, and at the same time reduce the situation where the raw materials are difficult to break up due to the surface tension between the powder and the liquid, thereby improving the overall mixing uniformity of the raw materials.

[0035] The first stirring mechanism includes a first motor 5, a first rotating shaft 51 and a spiral stirring blade 52. The first motor 5 is fixedly arranged on the side of the tank body 1. The first rotating shaft 51 is rotatably arranged in the tank body 1 and is transmission-connected to the output shaft of the first motor 5. The spiral stirring blade 52 is arranged on the first rotating shaft 51. When the first stirring mechanism is stirring and mixing, the first motor 5 is started to drive the first rotating shaft 51 to rotate, and the first rotating shaft 51 is used to mix and stir the raw materials in the tank body 1 through the spiral stirring blade 52.

[0036] The conveying assembly includes a second motor 6, a second rotating shaft 61 and a spiral conveying blade 62. The second motor 6 is fixedly arranged on the side of the feeding barrel 3. The second rotating shaft 61 is rotatably arranged in the feeding barrel 3 and is transmission-connected to the output shaft of the second motor 6. The spiral conveying blade 62 is connected to the second rotating shaft 61 and matches the internal space of the feeding barrel 3. The spiral conveying blade 62 is abutted and matched with the push rod 42.

[0037] When conveying powder and granular raw materials, the second motor 6 starts and drives the second rotating shaft 61 to rotate. At this time, the second rotating shaft 61 pushes the raw materials in the feeding barrel 3 to move through the spiral conveying blades 62, thereby realizing the conveying of the raw materials. At the same time, the spiral conveying blades 62 will abut and push the push rod 42 in a fixed position during rotation, thereby causing the push rod 42 to produce a relative rotation change, thereby causing the circular wheel 4 to rotate and make the dividing chamber 44 face the side of the feeding barrel 3 to put the granular raw materials into the mixing and conveying. In other embodiments, a number of shifting rods are also provided at intervals on the side of the second rotating shaft 61. In this way, during the rotation of the second rotating shaft 61, the shifting rods will also be used to shift the divided materials in the conveying process, thereby further causing the divided materials and the granular raw materials to be preliminarily mixed, which is more conducive to subsequent mixing needs.

[0038] Example 2: Figure 1-5 As shown, based on further improvement on Example 1, a material spreading mechanism is further provided between the feeding barrel 3 and the tank body 1, and the material spreading mechanism comprises a telescopic assembly, a rotating assembly and a material spreading plate, the telescopic assembly is provided on the outer upper side of the tank body 1 and is transmission-connected to the second rotating shaft 61, the rotating assembly is provided inside the tank body 1, and the material spreading plate is provided between the telescopic assembly and the rotating assembly.

[0039] The telescopic assembly includes an extension shaft 7, a loop 71 and a slide bar 72. The extension shaft 7 is rotatably arranged on the feed barrel 3 and is transmission-connected to the second rotating shaft 61. The loop 71 is slidably sleeved on the extension shaft 7. A movable groove 73 is opened on the upper side of the tank body 1. The slide bar 72 is connected to the loop 71 and is slidably connected to the movable groove 73 and extends into the tank body 1. A first guide groove 74 connected end to end is opened on the side of the extension shaft 7. The first guide groove 74 presents a sinusoidal structure when unfolded. The inner wall of the loop 71 is provided with a first guide head 75 movably embedded in the first guide groove 74.

[0040] The spreading plate includes a connecting rod 8 and a plurality of blades 81. The plurality of blades 81 are evenly arranged on the connecting rod 8 so that the vertical section of the connecting rod 8 presents a spline structure. The connecting rod 8 is rotatably connected to the sliding rod 72 and extends along the axial direction of the tank body 1. The position of the connecting rod 8 corresponds to the powder distribution port 45, and the connecting rod 8 is connected to the rotating component.

[0041] The rotating assembly includes a sleeve 9 and a second guide head 91. The sleeve 9 is hollow and fixedly arranged in the tank body 1 and is concentrically distributed with the connecting rod 8. The second guide head 91 is arranged in the sleeve 9. The connecting rod 8 slides into the sleeve 9 and has a second guide groove 92 connected end to end on the side. The second guide groove 92 presents a sinusoidal structure when unfolded, and the second guide head 91 is movably embedded in the second guide groove 92.

[0042] The number of sinusoidal wave peaks of the second guide groove 92 after it is expanded is greater than two, and the second guide groove 92 and the first guide groove 74 have the same length.

[0043] In order to further disperse the positions and areas where the raw materials are put into the tank body 1, during the conveying process of the second stirring mechanism, the primary mixture of the powder and granular raw materials will fall through the powder distribution port 45 and be blocked by the fan blades 81 in the scattering plate, and at the same time, the extension shaft 7 in the telescopic assembly will synchronize the rotation of the second rotating shaft 61, and the first guide groove 74 on the extension shaft 7 will guide the first guide head 75 in the loop 71, and the loop 71 is limited by the slide bar 72, so that the loop 71 can only move in the movable groove 73 through the slide bar 72. At this time, the slide bar 72 produces a push-pull action on the scattering plate, and the scattering plate produces a displacement change relative to the distribution port. Therefore, the falling distribution materials will be scattered on the scattering plate and will not be concentrated in one place, further During the forward and backward telescopic movement of the connecting rod 8 of the step-spreading plate, its end portion will telescope and move in the sleeve 9, and under the action of the second guide groove 92 and the second guide head 91, the spreading plate is forced to produce relative rotation during the telescopic process. Relative to the movement direction of the connecting rod 8, its rotation direction will also change. Therefore, during the rotation process, the material can be more dispersedly sprinkled to the left and right side areas of the tank body 1, thereby improving the mixing effect and further dispersing the powder raw materials. At the same time, by adjusting the number of sinusoidal wave peaks of the second guide groove 92, the rotation speed of the connecting rod 8 during the telescopic movement can be changed, that is, by increasing the rotation speed, the centrifugal force is increased, and then the distance over which the raw materials are sprinkled is increased, thereby further improving the mixing effect.

[0044] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
