Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, and more specifically, to a discharge auxiliary device for a kneader. Background Technology

[0002] A kneader is a specialized mixing and stirring device primarily used for processing high-viscosity, elastic-plastic materials such as rubber, plastics, and chemical raw materials. Through intense shearing, extrusion, and folding motions, it achieves uniform mixing of materials in a short time. Kneaders are widely used in various industries, including rubber, plastics, chemicals, food, and pharmaceuticals, and are characterized by uniform mixing, processing of high-viscosity materials, strong shearing effect, and versatility.

[0003] Based on the above, the inventors have discovered that traditional kneaders typically require manual removal of the mixed raw materials during the discharge process, which is cumbersome, inconvenient, and reduces the efficiency of raw material processing. In addition, the raw materials mixed by kneaders are usually quite viscous, and some of the raw materials may stick to the inner wall of the cylinder after mixing, leading to difficulties in discharge and waste of raw materials. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a discharge auxiliary device for kneaders, aiming to achieve a more practical purpose.

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a discharge auxiliary device for a kneader. It can be used with a cylinder, a connecting plate, and a pull rod to enable a scraper to reciprocate within the cylinder. During the movement of the scraper, the raw materials adhering to the inner wall of the cylinder can be scraped off, making discharge convenient and avoiding waste of raw materials. At the same time, two discharge ports are set at the bottom of the cylinder, and automatic discharge is achieved through two sets of discharge mechanisms composed of a screw rod, a discharge pipe, and a discharge motor, making discharge convenient and fast, and greatly improving the efficiency of raw material processing.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A discharge auxiliary device for a kneader includes a frame, a cylinder and a drive motor mounted on the top of the frame, two paddle shafts rotatably connected between the inner walls of the two ends of the cylinder via a rotating shaft, scrapers disposed between the inner walls of the two sides of the cylinder, cylinders fixedly mounted on both sides of the cylinder, a connecting plate disposed at the end of the cylinder away from the drive motor, two pull rods fixedly connected to the side of the connecting plate near the cylinder, one end of the pull rods extending into the cylinder and fixedly connected to the scrapers, the two ends of the connecting plate being fixedly connected to the output ends of the corresponding cylinders, two discharge ports opened at the bottom of the cylinder, and two sets of discharge mechanisms disposed at the bottom of the cylinder, with the discharge mechanisms corresponding to the positions of the discharge ports.

[0009] Furthermore, both ends of the rotating shaft extend to the outside of the cylinder body and are rotatably connected to the frame via bearing seats. One of the extended ends of the rotating shaft is connected to the output shaft of the drive motor via a coupling.

[0015] 3. Beneficial effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] (1) In this scheme, the cylinder is set up so that the cylinder works to drive the connecting plate to move back and forth. When the connecting plate moves, it drives the pull rod to move. The scraper is fixed on the pull rod. When the pull rod moves, the scraper also moves back and forth in the cylinder. Since the scraper is attached to the inner wall of the cylinder, it can scrape off the raw material stuck to the inner wall of the cylinder during the movement, so that the raw material can be quickly removed, thus avoiding the waste of raw material.

[0018] (2) This solution can achieve automatic discharge by setting two discharge ports at the bottom of the cylinder and by using two sets of discharge mechanisms consisting of a screw rod, a discharge pipe and a discharge motor, making discharge convenient and fast and greatly improving the efficiency of raw material processing.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0039] Example:

[0040] Please see Figures 1-5 A discharge auxiliary device for a kneader includes a frame 1. A cylinder 2 and a drive motor 3 are mounted on the top of the frame 1. Two paddle shafts 5 are rotatably connected between the inner walls of both ends of the cylinder 2 via a rotating shaft 4. Scrapers 6 are provided between the inner walls of both sides of the cylinder 2. Cylinders 7 are fixedly installed on both sides of the cylinder 2. A connecting plate 8 is provided at the end of the cylinder 2 away from the drive motor 3. Two pull rods 9 are fixedly connected to the side of the connecting plate 8 near the cylinder 2. One end of the pull rod 9 extends into the inside of the cylinder 2 and is fixedly connected to the scraper 6. The two ends of the connecting plate 8 are fixedly connected to the output ends of the corresponding cylinders 7. Two discharge ports 10 are opened at the bottom of the cylinder 2. Two sets of discharge mechanisms 11 are provided at the bottom of the cylinder 2, and the positions of the discharge mechanisms 11 and the discharge ports 10 are corresponding.

[0041] See Figure 2 Both ends of the rotating shaft 4 extend to the outside of the cylinder body 2 and are rotatably connected to the frame 1 through bearing seats. One of the extended ends of the rotating shaft 4 is connected to the output shaft of the drive motor 3 through a coupling.

[0042] See Figure 2 Two rotating shafts 4 are fixedly connected to gears 12 on the outer periphery of the extension ends near the drive motor 3, and the two gears 12 are meshed together.

[0043] See Figure 3 The outer side of the scraper 6 is fitted and connected to the inner wall of the cylinder 2.

[0044] See Figure 4 The discharge mechanism 11 includes a discharge pipe 1101 fixed to the bottom of the cylinder 2 and a discharge motor 1102 fixed to the bottom of the cylinder 2. A screw rod 1103 is rotatably connected between the inner walls of both ends of the discharge pipe 1101 through a bearing. One end of the screw rod 1103 extends to the outside of the discharge pipe 1101 and is connected to the output end of the discharge motor 1102 through a coupling.

[0045] See Figure 4 The top of one end of the discharge pipe 1101 is provided with a feed port 1104, which is connected to the inside of the cylinder 2 through the discharge port 10.

[0046] See Figure 4The other end of the discharge pipe 1101 has a discharge port at the bottom, and a discharge hopper 13 is fixedly installed at the discharge port.

[0047] In use: Place the raw materials into the cylinder 2, start the drive motor 3, and the drive motor 3 drives the rotating shaft 4. Under the action of the two gears 12, the two paddle shafts 5 can rotate alternately to mix the raw materials. After the raw materials are mixed, the cylinder 7 drives the connecting plate 8 to move back and forth. While the connecting plate 8 moves, it drives the pull rod 9 to move. The scraper 6 is fixed on the pull rod 9, so when the pull rod 9 moves, the scraper 6 also moves back and forth in the cylinder 2. Since the scraper 6 is attached to the inner wall of the cylinder 2, it can scrape off the raw materials adhering to the inner wall of the cylinder 2 during the movement. Finally, start the discharge motor 1102 to make the screw rod 1103 rotate. During the rotation of the screw rod 1103, the raw materials in the cylinder 2 are screwed into the discharge pipe 1101 and discharged through the discharge hopper 13 to realize automatic discharge. The entire discharge method is convenient and quick to operate, improves the efficiency of raw material processing, and avoids waste of raw materials.
