Technical Field
[0001] This utility model relates to the field of mixing device technology, and in particular to a mixing device for producing environmentally friendly plastic woven bags. Background Technology
[0002] Environmentally friendly plastic woven bags are flexible packaging containers made from recyclable or biodegradable materials through processes such as extrusion, stretching, and weaving. Their core objective is to reduce pollution from traditional plastics while meeting the packaging needs of industry, agriculture, and logistics. Compared to traditional plastic woven bags, environmentally friendly products place greater emphasis on resource recycling and environmental friendliness. The mixing device for producing environmentally friendly plastic woven bags is a specialized piece of equipment used to uniformly mix various raw materials (such as polypropylene, resin granules, recycled plastic granules, and environmentally friendly additives) required for the production of environmentally friendly plastic woven bags. Its core objective is to ensure thorough mixing of the raw materials to guarantee the quality stability and environmental performance of the woven bag products.
[0003] In existing technologies, mixing devices typically use heating to enhance the mixing effect and promote molecular movement during the mixing of multiple raw materials, allowing different components to penetrate and disperse more quickly and evenly. However, under heating conditions, the raw materials often develop or enhance their own stickiness. This stickiness causes the raw materials to adhere to the inner wall of the mixing device, preventing them from participating in subsequent mixing. This results in the actual proportion of materials participating in the mixing deviating from the formula design. Furthermore, this stickiness accumulates over time, further affecting the heating efficiency and mixing effect of the device. Therefore, it is necessary to improve the mixing device for the production of environmentally friendly plastic woven bags to solve the above problems. Utility Model Content

The mixing process involves conveying the mixed material inside the furnace body 1 via a conveying assembly, cleaning the inner wall of the furnace body 1 via a scraper 217, and simultaneously rotating the long rod 211 and the rotating sleeve 214 in opposite directions. The rotating sleeve 214 drives the scraper 217 to scrape away any remaining residue on the inner wall of the furnace body 1. Furthermore, the first mixing rod 213 and the second mixing rod 222 simultaneously mix in opposite directions, and their alternating distribution improves the mixing efficiency and the mixing effect of the raw materials inside the furnace body 1, thus enhancing the practicality of the device. The conveying assembly also improves the conveying of the mixed material, further enhancing the practicality of the device.
[0025] Please see Figure 2 - Figure 4In this embodiment, the fixing frame 216 has a corresponding groove at the corresponding position of the scraper 217. The scraper 217 is set in the groove of the fixing frame 216, which facilitates the installation and removal of the scraper 217, thereby improving the cleaning efficiency. There are four sets of first mixing rods 213 and five sets of second mixing rods 222. The four sets of first mixing rods 213 and the five sets of second mixing rods 222 are arranged alternately from top to bottom on the long rod 211 and the scraper 217, which improves the mixing effect of raw materials inside the furnace body 1 and enhances the practicality of the device. The furnace body 1 is fixedly connected to the insertion rod 21, and the top cover 5 is set on the insertion rod 21. The bottom of the top cover 5 is fixedly connected to the insertion frame 22, which is set inside the furnace body 1. The outside of the furnace body 1 is fixed. A fixed frame 23 is connected, and a locking block 24 is slidably connected inside the fixed frame 23. The locking block 24 penetrates the furnace body 1 and is engaged inside the insert frame 22. A smooth rod 25 is fixedly connected to the locking block 24 and slidably connected inside the fixed frame 23. A spring 26 is fixedly connected between the locking block 24 and the fixed frame 23. A lever 27 is fixedly connected to the smooth rod 25. A first motor 28 is fixedly connected to the top of the top cover 5. A first bevel gear 29 is fixedly connected to the output end of the first motor 28. An L-shaped bracket 210 is fixedly connected to the top of the top cover 5. A long rod 211 is rotatably connected inside the L-shaped bracket 210. A second bevel gear 212 is fixedly connected to the long rod 211. The first bevel gear 29 meshes with the outer surface of the second bevel gear 212. The rotating sleeve 214 is fixedly connected to a third bevel gear 215, and a first bevel gear 29 meshes with the outside of the third bevel gear 215. Bolts 218 are installed inside the scraper 217 and the fixing frame 216, and nuts 219 are threaded onto the outside of the bolts 218. A heating wire 220 is fixedly connected inside the furnace body 1, and a temperature sensor 221 is fixedly connected inside the furnace body 1 to detect the temperature of the inner cavity. A sealing ring 223 is fixedly connected to the bottom of the top cover 5, and a insertion frame 22 is located inside the sealing ring 223. The long rod 211 and the rotating sleeve 214 rotate synchronously in opposite directions, causing the rotating sleeve 214 to drive the scraper 217 to scrape away the residue remaining on the inner wall of the furnace body 1. Furthermore, the first mixing rod... 213 and the second mixing rod 222 perform synchronous reverse mixing, so that the two are staggered to improve the mixing efficiency and the mixing effect of raw materials inside the furnace body 1, thereby improving the practicality of the device. The top cover 5 has a matching through hole at the corresponding position of the insertion rod 21, and the insertion rod 21 passes through the through hole of the top cover 5, so that the top cover 5 can be limited during installation, thereby improving the stability and convenience of the installation of the top cover 5. The furnace body 1 has a matching groove at the corresponding position of the insertion frame 22, and the insertion frame 22 is set in the groove of the furnace body 1, so that the top cover 5 can be installed on the top of the furnace body 1, thereby improving the convenience of the installation of the top cover 5. The insertion frame 22 has a matching slot at the corresponding position of the locking block 24, and the locking block 24 is locked into the slot of the insertion frame 22.This facilitates the installation and removal of the top cover 5, improves the cleaning efficiency of the components on the top cover 5, and enhances the mixing effect of the raw materials.
[0026] Please see Figure 5 - Figure 6 In this embodiment, the conveying assembly includes a cylinder 31 fixedly connected to the support frame 4, a second motor 32 fixedly connected to the support frame 4, a feed hopper 33 fixedly connected to the cylinder 31 at the corresponding discharge port 7 position, a discharge hopper 34 fixedly connected to the cylinder 31, a rotating shaft 35 fixedly connected to the output end of the second motor 32, and a conveying auger 36 fixedly connected to the rotating shaft 35. The rotating shaft 35 is rotatably connected inside the cylinder 31, and the conveying auger 36 conveys the mixture. By conveying the mixed material after mixing, the conveying assembly improves the conveying of the mixed material after mixing, thereby improving the practicality of the device.
[0027] During operation, the support frame 4 supports the furnace body 1. The raw materials to be mixed are fed into the furnace body 1 through the feed inlet 6. The heating wire 220 is activated to heat the interior of the furnace body 1. The temperature sensor 221 allows for easy detection of the temperature inside the furnace body 1, which in turn increases the heating temperature of the heating wire 220, thereby improving the mixing efficiency. At this time, the first motor 28 is activated, driving the first bevel gear 29 to rotate. The second bevel gear 212 and the third bevel gear 215 mesh with the first bevel gear 29, synchronously driving the long rod 211 and the rotating sleeve 214. The rotating sleeve 214 rotates in the opposite direction, causing the first mixing rod 213 to rotate and mix the raw materials inside the furnace body 1. The rotating sleeve 214 not only drives the scraper 217 to scrape away residual residue on the inner wall of the furnace body 1, but also simultaneously mixes the first mixing rod 213 and the second mixing rod 222 in opposite directions. The staggered distribution of these two components improves the mixing efficiency and enhances the mixing effect inside the furnace body 1. When it is necessary to clean the scraper 217, the outward pulling of the pusher block 27 causes the locking block 24 to move away from the insert frame 22, compressing the spring 26 and releasing it from the top cover 5, thus removing the top cover 5 from inside the furnace body 1. The top cover 5 is pulled out to separate it from the furnace body 1. Then, the bolts 218 and nuts 219 are removed to disassemble the fixing bracket 216 and scraper 217, facilitating cleaning of the components on the top cover 5 and improving cleaning efficiency. After cleaning, the scraper 217 is installed on the fixing bracket 216 using the bolts 218 and nuts 219. The insertion frame 22 is then aligned with the corresponding groove in the furnace body 1, allowing the top cover 5 to be inserted into the insertion rod 21. When the insertion frame 22 contacts the arc end of the locking block 24, it moves outward, compressing the spring 26. This compresses the insertion frame 22... When inserted into the deepest part of the furnace body 1, the slot of the insert frame 22 corresponding to the corresponding position of the locking block 24 is in the corresponding position of the locking block 24. At this time, the compressed spring 26, through its own elasticity, causes the locking block 24 to engage in the slot of the insert frame 22, thus fixing the top cover 5. The top cover 5 and the furnace body 1 are sealed by the sealing ring 223. After the mixing is completed, the discharge port 7 is opened to let the mixed material fall into the feed hopper 33. At this time, the second motor 32 is started to drive the rotating shaft 35 to rotate inside the cylinder 31. The rotating conveying auger 36 conveys the mixed material, thereby improving the conveying of the mixed material and enhancing the practicality of the device.
[0028] Through the above steps, the long rod 211 and the rotating sleeve 214 rotate synchronously in opposite directions, so that the rotating sleeve 214 drives the scraper 217 to scrape off the residue remaining on the inner wall of the furnace body 1. Moreover, the first mixing rod 213 and the second mixing rod 222 mix synchronously in opposite directions. The staggered distribution of the two improves the mixing efficiency, which solves the problem that the mixed raw materials often generate or enhance their own stickiness under heating conditions. This stickiness causes the raw materials to adhere to the inner wall of the mixing device, making them unable to participate in subsequent mixing and affecting the heating efficiency and mixing effect of the device.
