Abstract
Description
Technical Field
[0001] This utility model relates to the field of thermoplastic elastomer technology, specifically to a mixing device for thermoplastic elastomers. Background Technology
[0002] Thermoplastic elastomers (TEEs) are a class of polymeric materials that combine the processing properties of thermoplastic plastics with the elasticity of rubber. Their characteristic is that they exhibit rubber-like elasticity at room temperature, while melting and flowing like plastic upon heating, allowing for repeated processing and molding. Therefore, thermoplastic elastomers can be produced by granulating various recycled thermoplastic elastomer products using a pelletizer. After granulation, the freshly produced thermoplastic elastomer granules are cooled to prevent them from sticking together at high temperatures.
[0003] Preparation before mixing requires pretreatment of raw materials: First, drying: hygroscopic components (such as TPU) need to be dried at 80-100℃ for 4-6 hours to avoid bubbles or degradation. Second, component premixing: premix powdered fillers (such as calcium carbonate) with liquid additives (white oil, plasticizer) to improve subsequent dispersion efficiency. Utility Model Content

[0025] The pre-construction structure 5 includes a side motor 11, a batching structure 12, a mixing blade 13, a material cylinder 14, an outlet valve 15, and a feed inlet 16. The material cylinder 14 is fixed to the top of the cover 2, and the side motor 11 is fixed to the top of the material cylinder 14. There are several batching structures 12, and each batching structure 12 is fixed to the top of the material cylinder 14. The mixing blade 13 is connected to the output end of the side motor 11. There are two outlet valves 15, and each outlet valve 15 is fixed to the bottom of the material cylinder 14.

The bracket is connected to the top of the material cylinder 14. The batching structure 12 and the collecting cylinder 17 include, but are not limited to, two.
[0026] The internal structures of the feeding device 9 and the batching structure 12 are basically the same. The batching structure 12 is also equipped with a top cover 92, a material pipe 93, a slide 94, a moving cup 95, a rotating cover 96, a rotating arm 97, a slide rail 941, an L-wall 942, a sliding plate 951, a measuring cup 952, and a connecting edge 953, so that the batching structure 12 has the function of quantitative feeding.
[0027] The start-up side motor 11 drives the mixing blade 13 to rotate. The mixing blade 13 premixes the powdered filler (such as calcium carbonate) and liquid additives (white oil, plasticizer) in the material cylinder 14 to improve the subsequent dispersion efficiency. During the process, the batching structure 12 quantitatively adds materials and controls the material ratio. The batching structure 12 controls the materials to enter the material cylinder 14 from the feed port 16. After being stirred by the mixing blade 13, the outlet valve 15 is opened and the materials fall into the main cylinder from the outlet valve.
[0028] The feeding device 9 includes a heat-insulating cylinder 91, a top cover 92, a feed tube 93, a slide 94, a moving cup 95, a rotating cover 96, and a rotating arm 97. The feed tube 93 is fixed to one side of the cover body 2. The heat-insulating cylinder 91 is connected to the top of the feed tube 93. The top cover 92 is connected to the top of the heat-insulating cylinder 91. The slide 94 is fixed to the side of the feed tube 93. The moving cup 95 is located below the slide 94. The rotating cover 96 is close to the bottom of the moving cup 95. A heating wire is connected to the inner wall of the heat-insulating cylinder 91. There are two rotating arms 97, and each rotating arm 97 is connected to both sides of the moving cup 95. The feed tube 93 passes through the middle of the cover body 2.
[0029] Open the top cover 92 and load the material into the insulation cylinder 91. The heating wire heats the insulation cylinder 91, which is filled with an insulation layer made of rock wool. The insulation cylinder 91 is also filled with a hygroscopic component such as TPU. The heating wire heats and dries the hygroscopic component. The material in the feed tube 93 falls into the moving cup 95 under gravity. The cylinder pushes the moving cup 95 to slide in the slide rail 94, causing the rotating cover 96 to rotate along the rotating arm 97. The material falls from the moving cup 95 into the main cylinder 1.
[0030] The slide 94 includes a frame slide 941 and an L-wall 942. The frame slide 941 is fixed to the lower side of the material tube 93, and the L-wall 942 is fixed to the side of the frame slide 941. The lateral end of the lower side of the L-wall 942 is close to the top of the rotating cover 96.
[0031] The movable cup 95 includes a slide plate 951, a measuring cup 952, and a connecting edge 953. The slide plate 951 is located inside the frame slide groove 941. The measuring cup 952 is fixed to the bottom of the slide plate 951. The connecting edge 953 is fixed to the side of the measuring cup 952. A cylinder is connected to the side of the slide plate 951 away from the connecting edge 953. An outlet runs through the middle of the slide plate 951, and the outlet corresponds to the bottom of the discharge pipe. The slide plate 951 slides within the slide rail of the frame slide groove 941.
[0032] The cylinder pushes the moving cup 95 to slide within the slide rail 94, that is, the cylinder pushes the sliding plate 951 to slide within the frame slide groove 941, causing the measuring cup 952 to move out of the lateral end of the lower side of the L-wall 942, so that the rotating cover 96 moves out of the lateral end of the L-wall 942. Under the action of gravity, the rotating cover 96 rotates along the rotating arm 97, and the material falls from the moving cup 95 into the main cylinder 1.
[0033] Working principle: Pre-drying structure 5 dries the hygroscopic components. Heating wires heat the material at 80-100℃ for 4-6 hours to prevent bubbles or degradation. The dried material is then quantitatively fed into the main cylinder by the feeding device 9. The motor 6 drives the belt 7, which in turn drives the impeller 10, causing the stirring blades 8 to agitate the material. Simultaneously, pre-drying structure 5 pre-stirs the fillers and other materials, improving subsequent dispersion efficiency. After stirring, the material falls into the main cylinder for further mixing.
[0034] The expected structure requires the start-up side motor 11 to drive the mixing blade 13 to rotate. The mixing blade 13 premixes the powdered filler such as calcium carbonate with liquid additives white oil and plasticizer in the material cylinder 14 to improve the subsequent dispersion efficiency. During the process, the batching structure 12 quantitatively adds materials and controls the material ratio. The batching structure 12 controls the materials to enter the material cylinder 14 from the feed port 16. After being stirred by the mixing blade 13, the outlet valve 15 is opened and the materials fall into the main cylinder from the outlet valve.
[0035] The loading device requires opening the top cover 92 to load the material into the insulation cylinder 91. The heating wire heats the insulation cylinder 91, which is filled with an insulation layer made of rock wool. The insulation cylinder 91 is filled with a hygroscopic component (such as TPU). The heating wire heats and dries the hygroscopic component. The material in the material tube 93 falls into the moving cup 95 under the influence of gravity. The cylinder pushes the moving cup 95 to slide in the slide rail 94, causing the rotating cover 96 to rotate along the rotating arm 97. The material falls from the moving cup 95 into the main cylinder 1.
[0036] The movement of the moving cup requires the cylinder to push the moving cup 95 to slide in the slide rail 94. That is, the cylinder pushes the slide plate 951 to slide in the frame slide groove 941, which drives the measuring cup 952 to move out of the horizontal end of the lower side of the L wall 942, so that the rotating cover 96 moves out of the horizontal end of the L wall 942. The rotating cover 96 is subjected to gravity and rotates along the rotating arm 97, and the material falls from the moving cup 95 into the main cylinder 1.

It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
