Description
Technical Field
[0001] The utility model relates to the technical field of plastic bag production, in particular to a mixer for plastic bag production. Background Art
[0002] Plastic bags are bags made of plastic (commonly used plastics include polypropylene, polyester, nylon, etc.) as the main raw material. They are indispensable items in people's daily lives and are often used to carry other items. They are widely used because of their advantages of being cheap, extremely light, large in capacity, and easy to store. However, due to their shortcomings of extremely long degradation cycle and difficult disposal, some countries have banned their production and use. Since June 1, 2008, China has implemented a plastic restriction order: a paid use system for plastic shopping bags has been implemented in all supermarkets, shopping malls, bazaars and other commodity retail places, and plastic shopping bags shall not be provided free of charge.
[0003] In the process of plastic bag production, different granular materials and raw materials need to be mixed according to the needs and colors of different plastic bags in order to carry out subsequent operations. The existing production process generally performs simple mixing. Due to the size of the granular materials, they need to be heated and then mixed during production to make the pigments and raw materials fully uniform. This method affects the production efficiency and does not have the mixing function of grinding the raw materials, as well as the coordinated flow mixing operation of the raw materials entering and discharging at the same time. Based on this, we propose a mixer for plastic bag production. Utility Model Content
[0004] The purpose of the utility model is to provide a mixer for producing plastic bags to solve the problems raised in the above background technology.

[0006] Preferably, the bottom end of the reinforcement frame is fixedly sleeved on the outer side of the top end of the first tank body, and a valve is provided inside the discharge pipe.
[0007] Preferably, the rotating rod movably passes through the top of the second tank body and extends to the inside of the second tank body through a bearing, the servo motor is fixed to the top of the second tank body through a bracket, and the top end of the cross bracket is movably sleeved on the outside of the rotating rod through a bearing.
[0008] Preferably, the discharge holes are spirally distributed evenly inside the discharge pipe, the specifications and dimensions of the spiral auger plate are compatible with the specifications and dimensions of the discharge pipe, and the discharge pipe is located inside the top end of the first tank body.
[0009] Preferably, the second servo motor is fixedly mounted on opposite sides of the first tank body and the guide cone.
[0010] Preferably, the guide pipe is movably plugged into the inner side of the upper grinding disc, and the specifications and dimensions of the lower grinding disc are matched with the specifications and dimensions of the upper grinding disc.
[0011] Compared with the prior art, the beneficial effect of the utility model is as follows: when the device is in use, the user connects the feed pipe to the granular material conveyor, connects the discharge pipe to the granular material collection and melting conveying equipment, and then starts servo motor 1 and servo motor 2. When the granular material enters the interior of the second tank body, the rotation of servo motor 1 drives the rotating rod to rotate and then drives the grinding blade to rotate, so that the granular material is initially crushed and falls into the interior of the discharge pipe. At this time, the spiral auger plate conveys the granular material upward under the rotation of the rotating rod. Smaller particles can pass through the filter and fall inside the guide cone, while larger particles are conveyed back to the inside of the second tank body through the filter, continue to be ground by the grinding blade, and fall into the guide cone. The particles on the side enter the upper grinding disc through the diversion of the diversion pipe. At this time, the servo motor 2 drives the driving gear to rotate, and the driving gear drives the meshing driven gear ring to rotate, thereby driving the upper grinding disc to rotate under the support of the support bearing, and the particles are ground into powder by the action of the upper grinding disc and the lower grinding disc, and then fall on the outer side of the fixed cone ring through the outer edge knife of the lower grinding disc and guide to the hollow support plate, fall into the inside of the first tank through the hollow support plate, and finally guide into the next process through the discharge pipe. This scheme can fully mix and crush the granular materials, and facilitate the subsequent melting processing after powdering, thereby improving the efficiency of the operation, facilitating the mixing of raw materials during the grinding process, and reducing the subsequent operation steps;
[0012] By setting the filter screen and spiral auger plate, when the granular material is ground and falls to the inside of the discharge pipe, due to the gap between the filter screen and the discharge pipe, as the rotating rod rotates, unsuitable granular material will be pushed back to the inside of the second tank body through the filter spiral for further grinding, and suitable granular material will enter the guide cone through the discharge hole and the filter screen, thereby improving the efficiency of granular material processing, facilitating uninterrupted fine grinding operations, stabilizing the operating effect, and improving the mixing efficiency.

[0020] The working principle of the above technical solution is as follows: when in use, the user connects the feed pipe 4 to the particle conveyor, connects the discharge pipe 7 to the particle collection, melting and conveying equipment, and then starts the servo motor 1 3 and the servo motor 2 12.
