Description

Technical Field

[0001] This utility model belongs to the field of raw material color mixing technology, and in particular relates to a raw material color mixing device for the production of plastic composite film bags. Background Technology

[0002] In the production process of plastic composite film bags, the raw material mixing device plays a crucial role. This equipment uses high-speed rotating blades to achieve vortex mixing, causing the plastic raw material to collide and rub against each other during high-speed movement. This generates heat and mixes evenly with the color powder. In addition, the design of the color mixer ensures that the moisture in the material can be quickly evaporated through the exhaust pipe, achieving a drying effect. This process not only achieves uniform color distribution but also ensures the drying quality of the material, thus meeting the stringent requirements of plastic composite film bag production.

[0003] Currently, raw material mixing devices on the market typically pour the raw materials into a mixing tank for coloring when performing the task of mixing and coloring plastic raw materials. However, due to the effect of gravity, the raw materials often remain at the bottom of the mixing tank, which increases the time required for the color mixing process and affects the operating efficiency of the color mixing machinery.

[0026] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0027] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] Please see Figures 1 to 5 This utility model provides a raw material mixing device for the production of plastic composite film bags, including a base 1. Two symmetrical first support frames 2 are installed on the upper side of the base 1. Each first support frame 2 is equipped with a first fixing rod 3. A mixing tank 4 is installed between the two first fixing rods 3. A feed inlet 5 is opened on the upper side of the mixing tank 4, and a discharge outlet 6 is opened on the lower side of the mixing tank 4. Both the discharge outlet 6 and the feed inlet 5 are equipped with baffles. A stirring assembly is installed inside the mixing tank 4.

[0029] Using the above scheme: When it is necessary to mix the raw materials of plastic composite film bags, the operator opens the feed inlet gate 5 and pours the raw materials of different colors into the mixing tank 4. After the raw materials are filled, the feed inlet gate 5 is closed and the stirring component is started. The rotation of the stirring component drives the raw materials to mix in the mixing tank 4, so that the raw materials of different colors can fully contact and blend. When the stirring component rotates, it can effectively turn over the raw materials stuck at the bottom of the mixing tank 4, preventing the raw materials from separating or settling due to long-term standing, thereby improving the uniformity of mixing.

[0030] Furthermore, the mixing assembly includes a first channel opened on the first fixed rod 3, and a first rotating shaft 7 is rotatably connected in the first channel; one end of the first rotating shaft 7 extends to another first fixed rod 3, and two symmetrical first stirring racks 8 are fixedly connected to the first rotating shaft 7; the first stirring rack 8 is located inside the color mixing tank 4, and a plurality of actuating rods 9 that fit against the inner wall of the color mixing tank 4 are installed on the first stirring rack 8.

[0031] Furthermore, the mixing assembly also includes a plurality of actuating frames 10 fixedly connected to the first rotating shaft 7, and a plurality of cutters 11 are fixedly connected inside each actuating frame 10.

[0032] Furthermore, a first gear 12 is installed at one end of the first rotating shaft 7; a second gear 13 meshes with one side of the first gear 12; a second rotating shaft 14 is installed at the center of the second gear 13; a first motor 15 is installed at one end of the second rotating shaft 14; and the first motor 15 is installed on the first support frame 2.

[0033] The above scheme is adopted as follows: In use, the first motor 15 drives the second rotating shaft 14 to rotate, so that the second gear 13 on it rotates synchronously. Then, the second gear 13 meshes with the first gear 12 to rotate synchronously. The rotation of the first gear 12 will drive the first rotating shaft 7 to rotate in the first channel. The rotation of the first rotating shaft 7 causes the first stirring rack 8 to rotate accordingly, and the agitator 9 on it will come into contact with the raw materials to stir them. At the same time, the agitator 9 also comes into contact with the inner wall of the mixing tank 4, so as to turn over the raw materials at the bottom of the mixing tank 4 and prevent the raw materials from being stuck.

[0034] It should be noted that while the first rotating shaft 7 is rotating, the agitator 10 can also stir the raw materials, and the multiple cutters 11 on it can break up raw materials of different consistency, thereby improving the uniformity of color mixing.

[0035] Furthermore, a second channel 16 is provided inside the first rotating shaft 7, and a plurality of liquid outlet holes 17 communicating with the second channel 16 are provided on the outer surface of the first rotating shaft 7.

[0036] Furthermore, one end of the second channel 16 is connected to a flexible hose via a rotary joint, and the other end of the flexible hose is connected to a pump body.

[0037] Using the above scheme: When the raw material after color mixing is discharged from the outlet 6, and it is necessary to clean the raw material remaining on the inner wall of the color mixing tank 4, the first rotating shaft 7 is driven to rotate. At the same time, the pump body injects liquid into the flexible hose. The liquid enters the second channel 16 through the flexible hose. As the first rotating shaft 7 continues to rotate, the liquid is sprayed onto the inner wall of the color mixing tank 4 through multiple liquid outlet holes 17 in the second channel 16, thereby cleaning the inner wall of the color mixing tank 4 and further improving the quality of color mixing.

[0038] It should be noted that: First, since the flexible hose is connected to the first rotating shaft 7 via a rotary joint, the flexible hose will not rotate with the first rotating shaft 7 when it rotates. Second, a valve can be installed at the connection point between the flexible hose and the second channel 16. When cleaning of the mixing tank 4 is not required, the valve is closed, and the raw material inside the mixing tank 4 will not flow out through the second channel 16. When cleaning of the mixing tank 4 is required, the valve is opened to clean the raw material residue on the inner wall of the mixing tank 4. Third, this liquid is clean water, and a suitable liquid can be selected to clean the mixing tank 4 according to the properties of the raw material.

[0039] Furthermore, the actuating rods 9 are evenly arranged on the first stirring frame 8, and the actuating rods 9 are made of rubber.

[0040] The working principle of this utility model:

[0041] When it is necessary to mix the raw materials for the plastic composite film bags, the operator opens the feed inlet gate 5 and pours raw materials of different colors into the mixing tank 4. After the raw materials are filled, the feed inlet gate 5 is closed. Driven by the first motor 15, the second rotating shaft 14 is rotated, and the second gear 13 on it rotates synchronously. Through the meshing of the second gear 13, the first gear 12 is driven to rotate synchronously. The rotation of the first gear 12 will drive the first rotating shaft 7 to rotate in the first channel. The rotation of the first rotating shaft 7 causes the first stirring rack 8 to rotate accordingly, and the agitator 9 on it will contact the raw materials in the mixing tank 4 to stir them. At the same time, the agitator 9 also contacts the inner wall of the mixing tank 4. The first rotating shaft 7 is driven to rotate, thereby turning over the raw materials at the bottom of the mixing tank 4 to prevent them from stagnating. While the first rotating shaft 7 is rotating, the agitator 10 can also stir the raw materials, and the multiple cutters 11 on it can break up raw materials of different consistency. When the mixed raw materials are discharged from the outlet 6, and it is necessary to clean the raw materials remaining on the inner wall of the mixing tank 4, the first rotating shaft 7 is driven to rotate. At the same time, the pump body injects liquid into the flexible hose. The liquid enters the second channel 16 through the flexible hose. As the first rotating shaft 7 continues to rotate, the liquid is sprayed onto the inner wall of the mixing tank 4 through the multiple liquid outlets 17 in the second channel 16, thereby cleaning the inner wall of the mixing tank 4.
