Abstract
Description
Technical Field
[0001] This utility model relates to the field of TPE granule production technology, and in particular to a mixing device for producing TPE granules. Background Technology
[0002] TPE is a thermoplastic elastomer material characterized by high strength, high resilience, and injection molding capability. It has a wide range of applications, is environmentally friendly, non-toxic, and safe, and possesses excellent colorability. TPE materials have a soft touch, good weather resistance, fatigue resistance, and temperature resistance. They offer superior processing performance, require no vulcanization, and can be recycled to reduce costs. They can be used for secondary injection molding, overmolding with matrix materials such as PP, PE, PC, PS, and ABS, or molded independently. However, in the production of TPE granules, to improve the yield, the raw materials need to be thoroughly mixed to produce qualified TPE granules. However, existing mixing and stirring devices have some problems in use:
[0003] 1. Existing TPE granules cannot quickly and effectively mix the raw materials to be mixed during the production and mixing process. Furthermore, continuous unidirectional mixing for a long time can also create some dead zones, resulting in some deficiencies in the overall processing and mixing of TPE granules.
[0004] 2. In the existing TPE granule mixing process, the problem of mixing dead zones has not been effectively improved, resulting in poor subsequent mixing effect of TPE granules. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a mixing device for producing TPE granules.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A mixing device for producing TPE granules includes an operating table. A rectangular through-slot is formed at the center of the top of the operating table, and support blocks are welded to both sides of the middle of the rectangular through-slot. A rotating shaft is rotatably mounted on the support blocks, and a mixing tank is welded between the two rotating shafts. A sealing cover is fixed to the top outer wall of the mixing tank, and a second drive motor is connected to the top axis of the sealing cover. The output shaft of the second drive motor is connected to a first stirring rod, and a first helical gear is welded to the bottom outer wall of the first stirring rod. A second helical gear meshes with the bottom of the first helical gear in a vertical direction, and a connecting shaft is welded to one side outer wall of the second helical gear. The connecting shaft is rotatably mounted on the inner wall of the mixing tank via a bearing, and a third helical gear meshes with the bottom of the second helical gear. A second stirring rod is welded to the bottom axis of the third helical gear.
[0008] As a further embodiment of this utility model: a worm gear is welded to one side of the outer wall of one of the rotating shafts, and a worm is engaged at the bottom of the worm gear. A first drive motor is connected to one side of the worm via a coupling.
[0009] As a further embodiment of this utility model: the top outer wall of the sealing cover is connected to a feeding hopper, and the top of the feeding hopper is hinged with a fixed cover.
[0010] As a further embodiment of this utility model: the bottom inner wall of the mixing tank is connected to a discharge pipe, and an electrically controlled valve is installed at the bottom of the discharge pipe.
[0011] As a further improvement of this utility model: electric telescopic rods are provided at both ends of the top of the operating table along the width direction, and an arc-shaped clamping block is fixed to the piston rod of the electric telescopic rod by screws, and an anti-slip pad is adhered to the inner wall of the arc-shaped clamping block.
[0012] As a further improvement of this utility model: the outer walls of both ends of the arc-shaped clamping block are welded with limit guide rods, and the limit guide rods are slidably inserted into the limit guide blocks, and the two arc-shaped clamping blocks are located on the same horizontal plane.
[0013] As a further improvement of this utility model: the dimensions of the first stirring rod and the second stirring rod are both adapted to the inner wall dimensions of the mixing tank, and the rotation direction of the first stirring rod is opposite to that of the second stirring rod.
[0014] Compared with the prior art, this utility model provides a mixing device for producing TPE granules, which has the following beneficial effects:
[0015] 1. The TPE granule mixing device designed in this paper uses a single drive motor to drive two stirring rods inside the mixing tank to rotate continuously. The two stirring rods in opposite directions can also fully mix the raw materials, which can improve the mixing efficiency.
[0016] 2. The TPE granule mixing device of this design addresses the mixing dead zones during the raw material mixing process by using a first drive motor to rotate the mixing tank. During the tumbling process, the raw materials are continuously turned over, thereby accelerating the mixing of the internal raw materials to the optimal state and effectively improving the mixing efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Example 1:
[0025] A mixing device for producing TPE granules, as described in this embodiment, Figure 1-4As shown, the system includes an operating table 1. A rectangular through-slot 2 is formed at the center of the top of the operating table 1. Support blocks 3 are welded to both sides of the middle of the rectangular through-slot 2. A rotating shaft 4 is rotatably mounted on the support block 3. A mixing tank 5 is welded between the two rotating shafts 4. A sealing cover plate 6 is fixed to the top outer wall of the mixing tank 5. A second drive motor 11 is connected to the top axis of the sealing cover plate 6. The output shaft of the second drive motor 11 is connected to a first stirring rod 12. A first helical gear 13 is welded to the bottom outer wall of the first stirring rod 12. A second helical gear 14 meshes with the bottom of the first helical gear 13 in a vertical direction. A connecting shaft 15 is welded to one side outer wall of the second helical gear 14. The connecting shaft 15 is rotatably mounted on the inner wall of the mixing tank 5 through a bearing. A third helical gear 16 meshes with the bottom of the second helical gear 14. A second stirring rod 17 is welded to the bottom axis of the third helical gear 16.
[0026] A single drive motor drives two stirring rods inside the mixing tank 5 to rotate continuously. The two stirring rods, which are arranged in opposite directions, can also fully mix the raw materials, thereby improving the mixing efficiency.
[0027] One of the rotating shafts 4 has a worm gear 7 welded to one side of its outer wall, and a worm 8 meshes with the bottom of the worm gear 7. One side of the worm 8 is connected to a first drive motor 9 via a coupling. The top outer wall of the sealing cover plate 6 is connected to a feed hopper 10, and a fixed cover is hinged to the top of the feed hopper 10.
[0028] The bottom inner wall of the mixing tank 5 is connected to a discharge pipe 18, and an electrically controlled valve is installed at the bottom of the discharge pipe 18.
[0029] The top two ends of the operating table 1 are provided with electric telescopic rods 19 along the width direction, and the piston rod of the electric telescopic rod 19 is fixed with an arc-shaped clamping block 20 by screws. The inner wall of the arc-shaped clamping block 20 is adhered with an anti-slip pad.
[0030] During the mixing process of raw materials, to address the problem of mixing dead zones, the first drive motor 9 drives the mixing tank 5 to rotate. During the tumbling process, the raw materials are continuously turned over, thereby accelerating the mixing of the internal raw materials to the optimal state and effectively improving the mixing efficiency.
[0031] In this embodiment, the TPE granules to be mixed are first loaded into the mixing tank 5. Then, the remaining parts are assembled and the external power supply is connected. When the TPE granules need to be mixed, the second drive motor 11 at the top is started, which drives the first stirring rod 12 and the second stirring rod 17 inside to rotate in opposite directions, thereby effectively mixing the TPE granules. For the problem of mixing dead corners, the first drive motor 9 on the side is started, which, with the help of the rotation and locking of the worm gear 7, can fully tumble and stir the TPE granules, thereby improving the mixing effect. When rotation and discharge are not required, the electric telescopic rod 19 drives the arc-shaped clamping blocks 20 to move closer to each other, thereby clamping and fixing the mixing tank 5 to ensure that the mixing tank 5 is in a vertical position.
[0032] Example 2:
[0033] A mixing device for producing TPE granules, such as Figure 1-4 As shown, this embodiment makes the following additions based on embodiment 1: the outer walls of both ends of the arc-shaped clamping block 20 are welded with limiting guide rods 21, and the limiting guide rods 21 are slidably inserted into the limiting guide block 22. The two arc-shaped clamping blocks 20 are located on the same horizontal plane. The dimensions of the first stirring rod 12 and the second stirring rod 17 are adapted to the inner wall dimensions of the mixing tank 5, and the rotation direction of the first stirring rod 12 is opposite to the rotation direction of the second stirring rod 17.
