Technical Field

[0001] The utility model belongs to the technical field of filling equipment, and in particular relates to a controllable phase change material liquid filling device. Background Art

[0002] Phase change materials (PCMs) are substances that change shape with temperature and can provide latent heat. Liquid PCMs are fluid and must therefore be contained or packaged in containers to prevent loss or environmental contamination. Filling equipment is required to fill liquid PCMs.

[0003] When using a filling device, the container to be filled needs to be positioned so that the liquid can be accurately filled into the container. However, existing filling devices can usually only position containers of the same size, which makes the filling device less applicable. In addition, during the filling process of existing filling devices, the liquid in the container is easily splashed out of the container, which may splash onto the worker and cause damage to the worker's skin or eyes. When the liquid is filled to the container mouth, the liquid is likely to overflow from the container mouth, thereby polluting the surrounding environment. Utility Model Content

[0008] As a further description of the above technical solution:

[0009] One side of the positioning block is connected to a connecting plate, one side of the connecting plate is connected to a first spring, the other end of the first spring is connected to a second moving block, one side of the second moving block is fitted with one side of the positioning block, and the tops of the two second moving blocks are fitted with the same positioning plate, the bottom of the positioning plate is respectively connected to a first fixed block and a second fixed block, and the bottoms of the first fixed block and the second fixed block are both connected to the top of the first moving block.

[0010] As a further description of the above technical solution:

[0011] The bottom of the second moving block is fitted with the top of the first moving block, the bottom of the second moving block is connected to a sliding block, the top of the first moving block is provided with two sliding grooves, the inner walls of the sliding grooves are slidably connected to the outer wall of the sliding block.

[0019] When the two lever are in the unlocked position, the two levers move upwards to push the two limit switches, and the two limit switches move in a reverse direction, so that the two limit switches move in a reverse direction, thereby adjusting the position of the two limit switches.

[0032] The specific implementation method is as follows: by setting a positioning mechanism 3, the two-way threaded rod 311 is driven to rotate by the output shaft of the motor 306. When the two-way threaded rod 311 rotates in the threaded block 314, the two threaded blocks 314 can be driven to move closer to or away from each other through the two opposite threads set on the outer wall of the two-way threaded rod 311. The movement of the threaded block 314 drives the limit block 316 to move, and the movement of the limit block 316 drives the positioning block 302 to move, so that the two positioning blocks 302 are closer to or away from each other, thereby being able to adjust the position between the two positioning blocks 302 according to the size of the container, and thus being able to position containers of different sizes, thereby improving the applicability of the filling device.

[0034] The specific implementation method is as follows: by setting up the splash-proof mechanism 5, when the cylinder 8 push rod drives the filling head 6 and the discharge pipe 9 to move downward, the filling head 6 can drive the baffle 501 and the absorbent paper 504 to move downward through the second spring 502, so that the baffle 501 and the absorbent paper 504 can block the container mouth, thereby preventing the liquid phase change material from splashing out of the container during the filling process, avoiding the liquid phase change material from splashing onto the workers and causing damage to the workers' skin or eyes, and preventing the liquid phase change material from overflowing from the container when the container is filled with liquid phase change material. This can avoid pollution to the surrounding environment. The setting of the spring allows the absorbent paper 504 and the baffle 501 to block the container mouth while the discharge pipe 9 can continue to move downward, so that it can be extended into the container. The setting of the absorbent paper 504 can prevent the liquid phase change material from accumulating on the baffle 501, thereby forming water droplets and falling, and further preventing the liquid phase change material from dripping out of the container and polluting the surrounding environment. By rotating the bolt 507, the fixing plate 505 can be driven downward to separate from the absorbent paper 504, so that the absorbent paper 504 can be replaced.

[0035] Working principle: When in use, place the filled container on the base 4, then start the motor 306, the output shaft of the motor 306 rotates to drive the bidirectional threaded rod 311 to rotate, because the outer wall of the bidirectional threaded rod 311 is provided with two opposite threads, so when the bidirectional threaded rod 311 rotates in the threaded block 314, it can drive the two threaded blocks 314 to move closer to or away from each other, and the movement of the threaded block 314 drives the limit block 316 and the positioning block 302 to move, so that the two positioning blocks 302 are closer to or away from each other, so that the position between the two positioning blocks 302 can be adjusted according to the size of the container. After the spacing between the positioning blocks 302 is reached, the electric push rod 2 is started, and the two electric push rods 2 on both sides drive the first moving block 307 to move. At the same time, the first moving block 307 can drive the positioning plate 301 to move through the first fixed block 312 and the second fixed block 313, so that the positioning plates 301, the second fixed block 313 and the first moving block 307 on both sides can contact the outer wall of the container and position the container. When the first moving block 307 moves, it can also drive the second moving block 308 to move through the sliding block 310. The second moving block 308 can drive the connecting plate 304 and the positioning block 301 through the first spring 303. 2 moves, so that the two positioning blocks 302 on both sides can approach each other and position the other two sides of the outer wall of the container. When the container is small, the two positioning blocks 302 on both sides will contact and be squeezed by each other and move in the direction of the tension of the first spring 303, so that the first moving block 307 can drive the positioning plate 301 and the first moving block 307 to continue to move toward the container through the first fixed block 312 and the second fixed block 313, and contact the container to position the container. After the positioning is completed, the cylinder 8 is started, and the cylinder 8 push rod moves to drive the filling head 6 and the discharge pipe 9 to move downward. At the same time, the filling head 6 can pass through the second The spring 502 drives the baffle 501 and the absorbent paper 504 to move downward, so that the baffle 501 and the absorbent paper 504 can block the container mouth to prevent the liquid phase change material from splashing or overflowing from the container during the filling process. The setting of the spring allows the absorbent paper 504 and the baffle 501 to block the container mouth while the discharge pipe 9 can continue to move downward so that it can extend into the container. The setting of the absorbent paper 504 can prevent the liquid phase change material from accumulating on the baffle 501, thereby forming water droplets and falling. By rotating the bolt 507, the fixing plate 505 can be driven downward to separate from the absorbent paper 504, so that the absorbent paper 504 can be replaced.
