Description

Technical Field

[0001] This utility model relates to the field of trough mixer technology, specifically a trough mixer with a safety protection structure. Background Technology

[0002] A trough mixer is a type of equipment commonly used in the pharmaceutical, food, chemical, and electronics industries, primarily for mixing powdery or paste-like materials. Its working principle mainly relies on the stirring action of an agitator to thoroughly mix two or more powdered materials within a trough.

[0003] Tank mixers are typically equipped with a tilting structure for unloading. The mixing chamber is mounted on the equipment and is difficult to remove, making internal cleaning quite troublesome. In this case, if the internal stirring shaft is not disassembled and cleaned, it will further increase the difficulty of cleaning the mixing chamber after processing. In addition, tank mixers mainly mix powder materials, and powder materials will inevitably be thrown up during the mixing process. Therefore, a tank mixer with an anti-overflow protection structure is required. Utility Model Content

[0004] The purpose of this invention is to provide a trough mixer with a safety protection structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a chassis and a mixing chamber. A processing groove is provided in the middle of the chassis. A controller is fixed to the front of the chassis. Both ends of the mixing chamber are rotatably connected to the processing groove via rotating shafts. A stirring shaft is rotatably connected inside the mixing chamber. Two mounting shafts are installed between the stirring shafts and are linearly distributed with the stirring shaft. End connecting sleeves are installed at the connection points between the mounting shafts and the stirring shaft. The two mounting shafts are inserted into a central connecting sleeve at their closest points and are fixed by a fixing component. A stirring rod is installed between the central connecting sleeve and the end connecting sleeve. A cover plate is installed above the mixing chamber. End blocks are fixed to both ends of the cover plate. A telescopic cylinder is fixed on the chassis at a position corresponding to the end blocks. The output end of the telescopic cylinder is fixed to the end blocks.

[0006] Preferably, the end of the stirring shaft has a square structure, the end connecting sleeve is fixed to the end of the mounting shaft away from the shaft, and has a square groove adapted to the end of the stirring shaft. One end of the stirring rod is fixed to the end connecting sleeve, and the other end is slidably connected to the central connecting sleeve.

[0007] Preferably, a limiting block is fixed at one end of the stirring rod near the central connecting sleeve, and a limiting groove adapted to the limiting block is opened on the outer side of the central connecting sleeve. The limiting block has a T-shaped structure and is slidably connected in the limiting groove.

[0008] Preferably, one end of the limiting groove is an open structure, a positioning block is installed at the bottom of the limiting groove near the opening, a telescopic groove is provided at the bottom of the limiting groove and at a position corresponding to the positioning block, and an ejector spring is fixed between the inner wall of the telescopic groove and the positioning block.

[0009] Preferably, the fixing component includes a blocking block and a bidirectional screw. The blocking block is installed in the middle position inside the central connecting sleeve and is symmetrically distributed. The inner wall of the central connecting sleeve is provided with a storage groove at a position corresponding to the blocking block. The bidirectional screw is rotatably connected inside the central connecting sleeve, with both ends located in the storage groove. The bidirectional screw passes through the blocking block and is threadedly connected to the blocking block.

[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution: including a chassis 1 and a mixing chamber 2. A processing groove 11 is provided in the middle of the chassis 1. A controller 12 is fixed on the front side of the chassis 1. The two ends of the mixing chamber 2 are rotatably connected to the processing groove 11 through a rotating shaft 21. A stirring shaft 22 is rotatably connected inside the mixing chamber 2. Two mounting shafts 3 are installed between the stirring shafts 22 and are arranged in a straight line with the stirring shafts 22. An end connecting sleeve 31 is installed at the connection between the mounting shafts 3 and the stirring shafts 22. The two mounting shafts 3 are inserted into a central connecting sleeve 4 at one end close to each other and are fixed by a fixing component. A stirring rod 32 is installed between the central connecting sleeve 4 and the end connecting sleeve 31. A cover plate 5 is installed on the top of the mixing chamber 2. End blocks 51 are fixed at both ends of the cover plate 5. A telescopic cylinder 52 is fixed on the chassis 1 at a position corresponding to the end blocks 51. The output end of the telescopic cylinder 52 is fixed on the end blocks 51.

[0019] The end of the stirring shaft 22 is square. The end connecting sleeve 31 is fixed to the end of the mounting shaft 3 away from the end and has a square groove adapted to the end of the stirring shaft 22. One end of the stirring rod 32 is fixed to the end connecting sleeve 31 and the other end is slidably connected to the central connecting sleeve 4. A limiting block 33 is fixed to the end of the stirring rod 32 near the central connecting sleeve 4. A limiting groove 41 adapted to the limiting block 33 is opened on the outside of the central connecting sleeve 4. The limiting block 33 is T-shaped and is slidably connected in the limiting groove 41. One end of the limiting groove 41 is open. A positioning block 42 is installed on the bottom of the limiting groove 41 near the opening. A telescopic groove 43 is opened at the bottom of the limiting groove 41 and at the position corresponding to the positioning block 42. An ejection spring 44 is fixed between the inner wall of the telescopic groove 43 and the positioning block 42.

[0020] The fixing component includes a blocking block 46 and a bidirectional screw 47. The blocking block 46 is installed in the middle of the central connecting sleeve 4 and is symmetrically distributed. The inner wall of the central connecting sleeve 4 is provided with a receiving groove 45 corresponding to the blocking block 46. The bidirectional screw 47 is rotatably connected in the central connecting sleeve 4, and both ends are located in the receiving groove 45. The bidirectional screw 47 passes through the blocking block 46 and is threadedly connected to the blocking block 46. The end of the bidirectional screw 47 extends out of the central connecting sleeve 4 and is fixed with a knob 48. The mounting shaft 3 is located in the central connecting sleeve 4, and one end is square. The end of the mounting shaft 3 close to the blocking block 46 abuts against the two sides of the blocking block 46 respectively.

[0021] Working principle: Rotating knob 48 drives the bidirectional screw 47 to rotate, causing the blocking block 46 to move along the direction of the bidirectional screw 47. When the blocking block 46 is retracted into the receiving groove 45, it loses its obstruction of the end of the mounting shaft 3. At this time, the mounting shaft 3 can be pushed into the central connecting sleeve 4, so that the end connecting sleeve 31 can be disconnected from the stirring shaft 22, and the mounting shaft 3 can be easily removed. Conversely, after the end connecting sleeve 31 is inserted into the end of the stirring shaft 22, the extension of the blocking block 46 prevents the mounting shaft 3 from retracting, thus achieving stable installation of the mounting shaft 3. In the process, the sliding of the mounting shaft 3 can synchronously drive the limiting block 33 to slide in the limiting groove 41. When the mounting shaft 3 is fixed, its ejection spring 44 will push out the positioning block 42, blocking the sliding of the limiting block 33, thus achieving the purpose of double limiting, thereby ensuring the stability of the mounting shaft 3 and the stirring rod 32 during rotation. Secondly, during the mixing process, the cover plate 5 can be lowered by the drive of the telescopic cylinder 52, so that it covers the upper plane opening of the mixing box 2, sealing the opening, reducing powder lifting, and also limiting the rotation of the mixing box 2, increasing its stability during operation.
