Description

Technical Field

[0001] This utility model relates to the field of sulfonic acid filling technology, and in particular to an auxiliary support for sulfonic acid filling. Background Technology

[0002] Sulfonic acid, as an important chemical raw material, has wide and crucial applications in many industrial fields, covering detergent manufacturing, petroleum refining, textile printing and dyeing, and many others. Currently, sulfonic acid filling operations are mainly carried out on specialized filling equipment. These devices are typically equipped with fixed filling nozzles to ensure the accuracy and stability of the filling process.

[0003] In actual production, various sizes of filling containers are used due to the diverse packaging requirements of different customers and the differences in production processes and transportation conditions. However, existing sulfonic acid filling equipment has a fixed filling nozzle position. When using smaller filling containers, the height between the filling platform and the filling nozzle is often much greater than the height of the filling container. This means that during the filling process, the filling container cannot be stably placed on the filling platform, and its bottom lacks effective support. To complete the filling operation, the filling personnel have to hold the filling container and fill it while it is suspended in the air. This operation method not only greatly increases the labor intensity of the filling personnel, but also easily leads to operator fatigue due to maintaining a hand-held posture for a long time, which in turn affects the accuracy and efficiency of filling. Sulfonic acid is usually corrosive and irritating. Due to operator fatigue or improper operation, the hand-held suspended filling method can easily lead to sulfonic acid splashing or leakage, thereby increasing the risk of sulfonic acid contact with personnel. Therefore, an auxiliary support for sulfonic acid filling is proposed. Utility Model Content

The cylinder is installed at the bottom of the filling platform. The movable end of the cylinder passes through the filling platform and is connected to a disc-shaped support plate. A ring-shaped positioning box is connected to the support plate. A clamping mechanism is provided inside the positioning box for clamping the filling container.

[0006] Preferably, the clamping mechanism includes four clamping plates, and four slide rails are connected in a circular array on the top inner wall of the positioning box. Each slide rail is slidably connected to a slide rod, and one end of each slide rod near the center of the support plate passes through the positioning box and is connected to the four clamping plates respectively.

[0007] Preferably, each slide rod is connected to a first spring at the end away from the clamping plate, and the other end of the first spring is connected to the inner wall of the positioning box. A fixed pulley is connected to the inner annular side wall of the positioning box below each slide rod. A fixing block is connected to the end of each slide rod near the first spring. Four rope holes are provided at the bottom of the support plate and the positioning box. A pull rope is connected to the fixing block. The end of the pull rope away from the fixing block is wound around the fixed pulley, passes through the rope hole, and is connected to a pull block. A second spring is connected to the bottom of the pull block, and the lower end of the second spring is connected to the filling table.

[0008] Preferably, the clamping plate has an arc-shaped structure.

[0009] Preferably, the spring constant of the first spring is smaller than that of the second spring.

[0016] 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.

[0017] Reference Figure 1-3As shown, an auxiliary support for sulfonic acid filling includes a filling platform 1 and a cylinder 2. The cylinder 2 is installed at the bottom of the filling platform 1. The movable end of the cylinder 2 passes through the filling platform 1 and is connected to a disc-shaped support plate 3. A ring-shaped positioning box 4 is connected to the support plate 3. A clamping mechanism is provided inside the positioning box 4 for clamping the filling container. The positions of the support plate 3 and the positioning box 4 are coaxial with the filling nozzle to ensure the accuracy of filling.

[0018] In this embodiment, the clamping mechanism includes four clamping plates 7. Four slide rails 5 are connected in a circular array on the top inner wall of the positioning box 4. A slide rod 6 is slidably connected on each slide rail 5. One end of each slide rod 6 near the center of the support plate 3 passes through the positioning box 4 and is connected to the four clamping plates 7 respectively. The clamping plates 7 have an arc-shaped structure that fits the filling container, increases the contact surface, and further improves the clamping stability.

[0019] In this embodiment, a first spring 8 is connected to one end of each slide rod 6 away from the clamping plate 7. The other end of the first spring 8 is connected to the inner wall of the positioning box 4. A fixed pulley 9 is connected to the inner annular side wall of the positioning box 4 and below each slide rod 6. A fixing block 10 is connected to one end of each slide rod 6 near the first spring 8. Four rope holes 12 are provided at the bottom of the support plate 3 and the positioning box 4. A pull rope 11 is connected to the fixing block 10. The end of the pull rope 11 away from the fixing block 10 is wound around the fixed pulley 9, passes through the rope hole 12, and is connected to a pull block 13. A second spring 14 is connected to the bottom of the pull block 13. The lower end of the second spring 14 is connected to the filling table 1.

[0020] In this embodiment, the spring constant of the first spring 8 is less than that of the spring constant of the second spring 14. When the rope 11 is pulled, the first spring 8 stretches before the second spring 14.

[0021] The positioning box 4, slide bar 6 and clamping plate 7 are all made of stainless steel, which has good corrosion resistance and strength and is suitable for sulfonic acid filling environment.

[0022] Working process and its principle: In use, the filling container is placed in the cylindrical placement slot formed by the support plate 3 and the positioning box 4. Then, the cylinder 2 is controlled to push the support plate 3 upward, so that the container mouth of the filling container is close to the filling nozzle. During the upward process, under the action of the pull rope 11, the four sliding rods 6 are pulled by the pull rope 11 and slide towards the center. Before clamping the filling container, the filling container is pushed to the center position, so that the filling container is aligned with the filling nozzle. When the clamping plate 7 contacts the filling container, the pull rope 11 stops moving, but the support plate 3 continues to rise, which will pull the second spring 14, increasing the pulling force on the pull rope 11, thereby ensuring the clamping force of the clamping plate 7 on the filling container and further improving the clamping stability of the filling container. After filling is completed, the cylinder 2 pulls the support plate 3 downward. Under the action of the first spring 8, the sliding rods 6 slide back to their original position, so that the clamping plate 7 automatically releases the clamping force on the filling container, making it convenient to replace the filling container.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
