Description

Technical Field

[0001] This utility model relates to the field of mixing machine technology, specifically a mixing machine for TPU film production. Background Technology

[0002] In the TPU film production process, the mixing stage is crucial. The uniformity and efficiency of mixing directly affect the quality of the TPU film. Therefore, a mixing machine is required in TPU film production. Existing technologies, such as the mixing machine for TPU film production disclosed in CN221365292U, while meeting mixing requirements to some extent, have a fixed mixing chassis. This means that the accumulation of raw materials at the bottom of the equipment during mixing is not effectively addressed, leading to uneven mixing and affecting quality. Furthermore, this type of equipment has a relatively limited operating mode, only suitable for mixing certain forms of raw materials, and cannot meet the mixing needs of diverse raw materials such as granules and fluids, thus limiting its applicability. Therefore, there is an urgent need for a mixing machine that can avoid raw material accumulation, improve mixing uniformity, and has multiple operating modes to improve the efficiency and quality of TPU film production and adapt to diverse production needs. Utility Model Content

[0003] The purpose of this invention is to provide a mixing machine for TPU film production to solve the aforementioned technical problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A mixing machine for TPU film production includes a support frame and a mixing tank. A tank bearing is sleeved on the outer wall of the mixing tank. Two mounting shafts are fixedly connected to the outer ring of the tank bearing. The two mounting shafts are symmetrically arranged about the mixing tank. One end of each mounting shaft is rotatably mounted on the support frame via a bearing. A worm gear is fixedly sleeved on one of the mounting shafts. A servo motor is fixedly mounted on the support frame. A worm is fixedly connected to the output shaft of the servo motor, and the worm meshes with the worm gear. A drive motor is fixedly mounted on the outer ring of the tank bearing. A drive gear is fixedly sleeved on the output shaft of the drive motor, and the drive gear meshes with a driven gear. A driven gear is fixedly sleeved on the outer wall of the mixing tank. An inner cylinder is installed inside the mixing tank. Multiple material-pushing strips are equidistantly installed on the inner wall of the inner cylinder. The cross-section of the material-pushing strips in the horizontal direction is triangular.

[0005] Preferably, the top of the mixing tank is bolted to a top cover, and a mixing mechanism is installed on the top cover. The mixing mechanism consists of mixing fins, a mixing shaft, and a mixing motor. The mixing motor is installed on the top cover, the top end of the mixing shaft is mounted through a bearing at the center of the top cover, the mixing fins are installed on the mixing shaft, and the output end of the mixing motor is connected to the top end of the mixing shaft.

[0006] Preferably, the top cover is provided with a feed inlet, a cap is threaded onto the feed inlet, and a wire clip is installed on the top surface of the top cover to fix the cable of the mixing motor of the mixing mechanism when the drive motor drives the mixing tank to rotate.

[0007] Preferably, the bottom of the mixing tank is funnel-shaped, and a discharge valve is installed at the discharge port at the bottom of the mixing tank.

[0008] Preferably, the inner cylinder is provided with a mounting flange at its top, and the mounting flange has multiple mounting holes. The mixing tank and the top cover are both provided with threaded holes corresponding to the mounting holes on the mounting flange.

[0009] Preferably, the mixing tank rotates under the action of the drive motor, and the materials in the mixing tank are mixed under the action of gravity. The material guide strips on the inner wall of the inner cylinder can make the raw materials move to a certain height before falling, thereby improving the uniformity of the mixing.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This invention uses a servo motor to drive a worm gear, causing the mixing tank to rotate horizontally on a support frame. The drive motor then rotates the mixing tank, allowing the internal materials to move and mix under the influence of gravity and the material-dispensing strips on the inner wall of the cylinder. This prevents material buildup at the bottom from hindering mixing, improving mixing uniformity. The inner cylinder can be flexibly removed as needed, allowing the device to function as a vertical mixing equipment for mixing fluids and other materials. It features multiple operating modes, a simple structure, and a wide range of applications. It effectively improves the mixing quality and efficiency of TPU film materials, meets diverse production needs, and is suitable for widespread use. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1 to 4 This utility model provides a technical solution: a mixing machine for TPU film production, comprising a support frame 1 and a mixing tank 2. A tank bearing 5 is sleeved on the outer wall of the mixing tank 2. Two mounting shafts 4 are fixedly connected to the outer ring of the tank bearing 5, symmetrically arranged about the mixing tank 2. One end of each mounting shaft 4 is rotatably mounted on the support frame 1 via a bearing. A worm gear 7 is fixedly sleeved on one of the mounting shafts 4. A servo motor 9 is fixedly mounted on the support frame 1. A worm 8 is fixedly connected to the output shaft of the servo motor 9, meshing with the worm gear 7. A drive motor 12 is fixedly mounted on the outer ring of the tank bearing 5. A drive gear 11 is fixedly sleeved on the output shaft of the drive motor 12, meshing with a driven gear 6. The driven gear 6 is fixedly sleeved on the outer wall of the mixing tank 2. An inner cylinder 14 is installed inside the mixing tank 2, and multiple feeding strips 15 are equidistantly installed on the inner wall of the inner cylinder 14.

[0019] Furthermore, a top cover 3 is bolted to the top of the mixing tank 2, and a mixing mechanism 13 is installed on the top cover 3. The mixing mechanism 13 consists of mixing fins, a mixing shaft, and a mixing motor. The mixing motor is installed on the top cover 3, and the top end of the mixing shaft is installed at the center of the top cover 3 through a bearing. The mixing fins are installed on the mixing shaft, and the output end of the mixing motor is connected to the top end of the mixing shaft.

[0020] Furthermore, the top cover 3 is provided with a feed inlet, and a cap is threaded onto the feed inlet. A wire clip is installed on the top surface of the top cover 3 for fixing the cable of the mixing motor of the mixing mechanism 13. The bottom of the mixing tank 2 is funnel-shaped, and a discharge valve 10 is installed at the discharge port at the bottom of the mixing tank 2.

[0021] Furthermore, the inner cylinder 14 is provided with a mounting flange at its top, and the mounting flange has multiple mounting holes. The mixing tank 2 and the top cover 3 are both provided with threaded holes corresponding to the mounting holes on the mounting flange.

[0022] Furthermore, the mixing tank 2 rotates under the action of the drive motor 12, and the materials in the mixing tank 2 are mixed under the action of gravity. The material guide bar 15 on the inner wall of the inner cylinder 14 can make the raw material move to a certain height and then fall down, thereby improving the uniformity of the mixing.

[0023] The working process of this utility model is as follows:

[0024] like Figure 1 - Figure 4 As shown, when mixing the raw materials for TPU film, the polyurethane granules, additives, and other raw materials, after being weighed according to the specified ratio, are first added into the mixing tank 2 through the feed port on the top cover 3. The cap on the feed port can be threaded and sealed after the materials are added. The servo motor 9 is activated by the control switch, and its output shaft drives the worm gear 8 to rotate. The worm wheel 7, which meshes with the worm gear 8 and is fixedly sleeved on one end of the mounting shaft 4, rotates accordingly, causing the mixing tank 2 to rotate on the support frame 1 and become horizontal (the mixing tank can be horizontal or inclined). Subsequently, the drive motor 12 is activated, and its output shaft drives the drive gear 11 to rotate. Because the drive gear 11 meshes with the driven gear 6 fixedly sleeved on the mixing tank 2, the mixing tank 2 rotates under the support of the tank bearing 5. The internal materials are mixed under the action of gravity. The material-pulling strips 15, which are equidistantly installed on the inner wall of the inner cylinder 14 inside the mixing tank 2, cause the raw materials to fall after moving to a certain height, avoiding accumulation at the bottom and improving the uniformity of mixing.

[0025] When used as a vertical mixing device, the inner cylinder 14 can be removed by removing the bolts through the mounting holes on the flange at the top of the inner cylinder 14 and the corresponding threaded holes on the mixing tank 2 and the top cover 3. It can then be used for mixing fluids and other raw materials. In addition, the mixing mechanism 13 on the top cover 3 drives the mixing shaft and mixing fins to rotate to assist in mixing when the mixing motor is working. When working in the horizontal position, after the mixing mechanism 13 is de-energized, the cable is fixed by the wire clamp on the top cover. After mixing is completed, the material is discharged through the discharge valve 10 at the funnel-shaped discharge port at the bottom of the mixing tank 2.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
