Description

Technical Field

[0001] This utility model belongs to the field of TPU production technology, specifically a TPU raw material preparation device. Background Technology

[0002] TPU stands for thermoplastic polyurethane elastomer rubber, which is mainly divided into polyester type and polyether type. It has a wide hardness range, is wear-resistant, oil-resistant, transparent, and has good elasticity. It is widely used in daily necessities, sporting goods, toys, decorative materials and other fields. Halogen-free flame-retardant TPU can also replace soft PVC to meet the environmental protection requirements of more and more fields.

[0003] Existing technologies suffer from insufficient mixing of raw materials, resulting in poor uniformity after mixing, which in turn affects product quality.

[0004] Therefore, this utility model provides a TPU raw material preparation device. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A TPU raw material mixing device of this utility model includes a mixing box; a cover is installed on the top of the mixing box; an inlet is opened on one side of the mixing box; an outlet is opened on the other side of the mixing box; a motor is fixedly connected to the top of the cover; a feed pipe is fixedly connected to one side of the inlet; a rotating shaft is fixedly connected to the bottom of the motor; the rotating shaft is rotatably connected to the cover; multiple straight shafts are fixedly connected to the outside of the rotating shaft; multiple support rods are fixedly connected to the outside of the straight shafts; multiple first rotating blades are rotatably connected to one end of each support rod. During operation, the ingredients are first placed into the feed pipe; after pretreatment, the ingredients pass through the inlet. The ingredients are introduced into the mixing tank. Once the tank is full, the motor is started. The motor drives the rotating shaft to rotate, which in turn moves the straight shaft within the mixing tank, stirring the ingredients. As the straight shaft moves, it also moves the support rod. The first rotating blade contacts the ingredients, and under the action of the ingredients being stirred by the straight shaft, the first rotating blade rotates, further mixing the ingredients around it. By setting the motor to drive the rotating shaft and straight shaft to rotate, the ingredients are stirred and mixed. When the straight shaft drives the support rod to stir the ingredients, it also drives the first rotating blade to rotate, further stirring the ingredients and making them more thoroughly mixed. This setup allows for stirring and mixing the ingredients in multiple directions, resulting in a more uniform blend and further ensuring product quality.

[0007] Preferably, a guide ball is fixedly connected to one end of the straight shaft, and an extension rod is provided on one side of the guide ball. One end of the extension rod is rotatably connected to the mixing box, and the other end of the extension rod is fixedly connected to multiple second rotating blades. During operation, the straight shaft drives the guide ball to rotate, and the guide ball contacts the second rotating blades on the mixing box, causing the extension rod to rotate, thereby stirring the ingredients near the inner wall of the mixing box and making them evenly mixed. By setting the guide ball, extension rod, and second rotating blades to work together, the ingredients in the mixing box are thoroughly and evenly mixed, reducing the problem of uneven mixing of ingredients due to insufficient stirring, which leads to poor product quality.

[0008] Preferably, a cylinder is fixedly connected to one end of the feed pipe, and a push block is fixedly connected to one end of the cylinder. The push block is slidably connected to the feed pipe. Two connecting rods are hinged to one side of the push block, and a first baffle is hinged to one end of each connecting rod. The first baffle is slidably connected to the feed pipe. During operation, after the pre-processing of the ingredients entering the feed pipe, the cylinder is activated, and the cylinder pushes the push block to move, pushing the ingredients towards the feed inlet. During this process, the push block pushes the connecting rods to change angle, which in turn pushes the first baffle to move. The first baffle slides upward along the feed pipe, ensuring that the ingredients pass smoothly through the feed inlet and enter the mixing tank completely. Subsequently, the push block resets, causing the first baffle to fall and seal the feed inlet, ensuring the sealing of the ingredients during the mixing process in the mixing tank.

[0009] Preferably, the top of the feed pipe is provided with a dispensing port, the top of the dispensing port is hinged with a sealing plate, the top of the sealing plate is connected to an external air pipe, and the bottom of the sealing plate is connected to multiple air holes. During operation, the ingredients enter the feed pipe from the dispensing port, then the sealing plate is closed, the external air pipe is connected to hot air, and then the hot air is released from the air holes, acting on the ingredients in the feed pipe to perform a pre-treatment of drying and dehydration. Then, the ingredients are pushed into the mixing box by the pusher block, and the pre-treated ingredients are fully mixed in the mixing box.

[0010] Preferably, one end is fixedly connected to a discharge pipe, and a second baffle is slidably connected to the middle of the discharge pipe. A pull rod is fixedly connected to the top of the second baffle. During operation, the second baffle blocks the discharge pipe to ensure the sealing of the mixing box. When discharging, the pull rod is pulled to slide the second baffle upward and expose it. The discharge pipe guides the discharge, reducing the occurrence of ingredients coming out directly from the discharge pipe and contaminating the mixing box.

[0011] Preferably, the top of the pull rod is provided with a hook, which is fixedly connected to the mixing box. The hook corresponds to the pull rod. During operation, the pull rod is hung on the hook, which can reduce the need for manual support of the pull rod and facilitate material discharge.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The TPU raw material mixing device of this utility model is configured to use a motor to drive a rotating shaft and a straight shaft to rotate, thereby stirring and mixing the ingredients. When the straight shaft drives the support rod to stir the ingredients, it will also drive the first rotating blade to rotate, further stirring the ingredients to make them more thoroughly mixed. This configuration allows for stirring and mixing the ingredients in multiple directions, making them more uniformly blended and further ensuring product quality.

[0014] 2. The TPU raw material mixing device of this utility model, by setting a guide ball, an extension rod and a second rotating blade to cooperate with each other, makes the ingredients in the mixing box fully and evenly mixed, reducing the problem of uneven mixing of ingredients due to insufficient stirring, which leads to poor product quality.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 3As shown in the embodiment of this utility model, a TPU raw material mixing device includes a mixing box 1; a cover 11 is installed on the top of the mixing box 1, an inlet 101 is opened on one side of the mixing box 1, and an outlet 102 is opened on the other side of the mixing box 1. A motor 12 is fixedly connected to the top of the cover 11, a feed pipe 13 is fixedly connected to one side of the inlet 101, a rotating shaft 14 is fixedly connected to the bottom of the motor 12, the rotating shaft 14 is rotatably connected to the cover 11, a plurality of straight shafts 15 are fixedly connected to the outside of the rotating shaft 14, a plurality of support rods 16 are fixedly connected to the outside of the straight shafts 15, and a plurality of first rotating blades 17 are rotatably connected to one end of the support rods 16. During operation, the ingredients are first placed into the feed pipe 13, and after pretreatment, the ingredients pass through the inlet 101 and enter the feed pipe 13. The ingredients are placed into the mixing tank 1. After the mixing tank 1 is filled with ingredients, the motor 12 is started. The motor 12 drives the rotating shaft 14 to rotate, and then the straight shaft 15 moves within the ingredients to stir them. When the straight shaft 15 moves, it drives the support rod 16 to move. The first rotating blade 17 comes into contact with the ingredients. Under the action of the ingredients stirred by the straight shaft 15, the first rotating blade 17 rotates, further mixing the ingredients around the first rotating blade 17. By setting the motor 12 to drive the rotating shaft 14 and the straight shaft 15 to rotate, the ingredients are stirred and mixed. When the straight shaft 15 drives the support rod 16 to stir the ingredients, it will drive the first rotating blade 17 to rotate, further stirring the ingredients to make them more thoroughly mixed. This setting allows for stirring and mixing of the ingredients in multiple directions, making them more uniform and further ensuring product quality.

[0024] like Figures 1 to 3 As shown, a guide ball 2 is fixedly connected to one end of the straight shaft 15. An extension rod 21 is provided on one side of the guide ball 2. One end of the extension rod 21 is rotatably connected to the mixing box 1, and the other end of the extension rod 21 is fixedly connected to multiple second rotating blades 22. During operation, the straight shaft 15 drives the guide ball 2 to rotate, and the guide ball 2 will contact the second rotating blades 22 on the mixing box 1, causing the extension rod 21 to rotate, thereby stirring the ingredients near the inner wall of the mixing box 1 and making them evenly mixed. By setting the guide ball 2, the extension rod 21 and the second rotating blades 22 to cooperate with each other, the ingredients in the mixing box 1 are thoroughly and evenly mixed, reducing the problem of uneven mixing of ingredients due to insufficient stirring, which leads to poor product quality.

[0025] like Figures 1 to 4As shown, a cylinder 3 is fixedly connected to one end of the feed pipe 13, and a push block 31 is fixedly connected to one end of the cylinder 3. The push block 31 is slidably connected to the feed pipe 13. Two connecting rods 32 are hinged to one side of the push block 31, and a first baffle 33 is hinged to one end of the connecting rod 32. The first baffle 33 is slidably connected to the feed pipe 13. During operation, after the pre-processing of the ingredients entering the feed pipe 13, the cylinder 3 is started. The cylinder 3 pushes the push block 31 to move, pushing the ingredients towards the feed inlet 101. During this process, the push block 31 pushes the connecting rod 32 to change its angle, and then the connecting rod 32 pushes the first baffle 33 to move. The first baffle 33 slides upward along the feed pipe 13 to ensure that the ingredients pass smoothly through the feed inlet 101 and all enter the mixing box 1. Then the push block 31 resets, causing the first baffle 33 to fall down and seal the feed inlet 101, ensuring the sealing of the ingredients mixing process in the mixing box 1.

[0026] like Figures 1 to 4 As shown, the top of the feed pipe 13 is provided with a dispensing port 4, and a sealing plate 41 is hinged to the top of the dispensing port 4. An external air pipe 42 is connected to the top of the sealing plate 41, and multiple air holes 43 are connected to the bottom of the sealing plate 41. During operation, the ingredients enter the feed pipe 13 from the dispensing port 4, and then the sealing plate 41 is closed. The external air pipe 42 is connected to hot air, and then the hot air is released from the air holes 43, acting on the ingredients in the feed pipe 13 to perform a pre-treatment of drying and dehydration. Then, the ingredients are pushed into the mixing box 1 by the pusher block 31. The pre-treated ingredients are fully mixed in the mixing box 1.

[0027] like Figures 1 to 5 As shown, a discharge pipe 5 is fixedly connected to one end of the discharge port 102. A second baffle 51 is slidably connected to the middle of the discharge pipe 5. A pull rod 52 is fixedly connected to the top of the second baffle 51. During operation, the second baffle 51 blocks the discharge pipe 5 to ensure the sealing of the mixing box 1. When discharging, the pull rod 52 is pulled to slide the second baffle 51 upward, exposing the discharge port 102. The discharge pipe 5 guides the discharge, reducing the occurrence of ingredients coming out directly from the discharge port 102 and contaminating the mixing box 1.

[0028] like Figures 1 to 5 As shown, the top of the pull rod 52 is provided with a hook 6, which is fixedly connected to the mixing box 1. The hook 6 corresponds to the pull rod 52. During operation, the pull rod 52 is hung on the hook 6, which can reduce the need for manual support of the pull rod 52 and facilitate material discharge.

[0029] Working principle: First, the ingredients are placed into the feed pipe 13. After pretreatment, the ingredients enter the mixing tank 1 through the feed inlet 101. After the mixing tank 1 is full, the motor 12 is started. The motor 12 drives the rotating shaft 14 to rotate, and then the straight shaft 15 moves inside the ingredients to stir them. When the straight shaft 15 moves, it drives the support rod 16 to move. The first rotating blade 17 comes into contact with the ingredients. Under the action of the ingredients stirred by the straight shaft 15, the first rotating blade 17 rotates, further mixing the ingredients around the first rotating blade 17. By setting the motor 12 to drive the rotating shaft 14 and the straight shaft 15 to rotate, the ingredients are stirred and mixed. The straight shaft 15 drives the support rod 16 to move. 6. When the mixing motion is activated, it drives the first rotating blade 17 to rotate, further agitating the ingredients and ensuring thorough mixing. This arrangement allows for multi-directional mixing of the ingredients, resulting in more uniform mixing and further guaranteeing product quality. The straight shaft 15 drives the guide ball 2 to rotate, which then contacts the second rotating blade 22 on the mixing tank 1, causing the extension rod 21 to rotate. This, in turn, agitates the ingredients near the inner wall of the mixing tank 1, ensuring uniform mixing. By coordinating the guide ball 2, extension rod 21, and second rotating blade 22, the ingredients within the mixing tank 1 are thoroughly and evenly mixed, reducing uneven mixing caused by insufficient agitation and resulting in poor product quality. The problem is that after the pre-processing of the ingredients in the feed pipe 13, the cylinder 3 is started. The cylinder 3 pushes the pusher block 31 to move, pushing the ingredients towards the feed inlet 101. During this process, the pusher block 31 pushes the connecting rod 32 to change its angle, and then the connecting rod 32 pushes the first baffle 33 to move. The first baffle 33 slides upward along the feed pipe 13 to ensure that the ingredients pass smoothly through the feed inlet 101 and all enter the mixing box 1. Then the pusher block 31 resets, causing the first baffle 33 to fall and seal the feed inlet 101, ensuring the airtightness of the mixing process in the mixing box 1. The ingredients enter the feed pipe 13 from the ingredient inlet 4, and then the sealing plate 41 is closed, and the external air pipe 42... Hot air is connected and then released from the air hole 43, acting on the ingredients in the feed pipe 13 to perform a pre-treatment of drying and dehydration. Then, the ingredients are pushed into the mixing box 1 by the pusher block 31. The pre-treated ingredients are fully mixed in the mixing box 1. The second baffle 51 blocks the discharge pipe 5 to ensure the airtightness of the mixing box 1. When discharging, the pull rod 52 is pulled to slide the second baffle 51 upward, exposing the discharge port 102. The discharge pipe 5 guides the discharge, reducing the phenomenon of ingredients coming out directly from the discharge port 102 and contaminating the mixing box 1. The pull rod 52 is hung on the hook 6, which can reduce the need for manual holding of the pull rod 52 and facilitate the discharge operation.
