Description

Technical Field

[0001] The present invention relates to filling equipment, and more specifically to an automatic chemical filling equipment. Background Art

[0002] In the field of chemical production, the filling operation of chemicals is an important and common operation. Traditional chemical filling methods mainly rely on manual operation or simple mechanical equipment, and there are many problems.

[0003] In the early manual filling method, workers need to manually control the filling volume and liquid level height. This not only has a high labor intensity and low work efficiency, but also is prone to inaccurate filling accuracy due to human factors, resulting in underfilling or overflow. The spilled chemicals not only cause waste, but also may pollute the environment and even endanger the safety of operators.

[0004] With the development of technology, some semi-automatic filling equipment has gradually emerged. Although these equipment have improved the filling efficiency to a certain extent, there are still some deficiencies. For example, some equipment only relies on a single weighing sensor or liquid level sensor to control the filling process. If only relying on the weighing sensor, when there is an error in the weight of the filling barrel or the material density changes, it is easy to cause the actual filling volume to deviate from the preset value; if only relying on the liquid level sensor, in some special cases, such as when there is foam on the surface of the material or the liquid level fluctuates greatly, misjudgment may occur, affecting the filling accuracy.

[0005] In addition, traditional filling equipment also has limitations in terms of adaptability and flexibility. Different specifications of filling barrels require different filling heights and filling head spacings, and many existing equipment are difficult to adjust quickly and conveniently, resulting in a narrow application range of the equipment. Moreover, the structural design of these equipment is often relatively complex, difficult to maintain. Once a failure occurs, the repair time is long, affecting the production progress.

[0042] The following combines the appended Figures 1-5 to further elaborate in detail on the detailed implementation manners of the present invention.

[0043] An embodiment, given by Figures 1-5 The present invention provides an automatic chemical filling device, including:

[0044] Frame 1;

[0052] The filling head 13 is installed on the spacing adjustment mechanism and is used for filling the filling barrels.

[0053] The first guiding column 8 is symmetrically fixed to the tops of both sides of the U-shaped frame 7 and penetrates through the adjustment mechanism 5.

[0054] The weighing mechanism 4 includes a base 10 arranged at the bottom, a pressure sensor 11 installed on the base 10, and a bearing platform 12 installed at the top of the pressure sensor 11. The pressure sensor 11 is used for collecting the gravity signal of the material on the bearing platform 12.

[0055] The infrared sensor 14 is embedded and installed at the end of the filling head 13 and is used for collecting the liquid level height signal in the filling barrel.

[0056] The processing module 25 is installed at the bottom of the adjustment mechanism 5 and is electrically connected to the pressure sensor 11 and the infrared sensor 14 respectively. It is configured as follows: when the signals collected by the pressure sensor 11 and the infrared sensor 14 both meet the preset values, the processing module 25 confirms that the filling is completed; when one of the signals collected by the pressure sensor 11 and the infrared sensor 14 does not meet the preset value, the processing module 25 issues an instruction to the filling head 13 to continue filling.

[0057] Frame 1: The main support structure of the equipment.

[0058] Fixed beam 2: Fixed to the top of the frame 1 and used for supporting other components.

[0059] Fixed horizontal plate 3: Fixed to the top of the fixed beam 2 and providing an installation basis for the adjustment mechanism 5.

[0060] Weighing mechanism 4: Installed on one side below the frame 1, including a base 10, a pressure sensor 11, and a bearing platform 12, and is used for collecting the gravity signal of the filling material.

[0061] Adjustment mechanism 5: Installed on the fixed horizontal plate 3, including a lifting plate 15, a lead screw 16, a connecting block 17, a crank 18, a second guiding column 19, etc., and is used for adjusting the height of the filling head 13.

[0062] Lifting cylinder 6: Installed on the adjustment mechanism 5 and used for driving the lifting of the U-shaped frame 7.

[0063] U-shaped frame 7: Installed at the free end of the lifting cylinder 6 and used for installing the spacing adjustment mechanism and the filling head 13.

[0064] Spacing adjustment mechanism: Installed at the bottom end of the U-shaped frame 7, including a cross bar 22, a moving block 23, etc., and is used for adjusting the spacing of the filling head 13 to adapt to filling barrels of different specifications.

[0065] Filling head 13: Installed on the spacing adjustment mechanism and used for filling the filling barrels.

[0066] The first guiding column 8: symmetrically fixed to the tops of both sides of the U-shaped frame 7 and passing through the adjusting mechanism 5 to ensure the vertical movement of the U-shaped frame 7.

[0067] The infrared sensor 14: embedded and installed at the end of the filling head 13 for collecting the liquid level height signal in the filling barrel.

[0068] The processing module 25: installed at the bottom of the adjusting mechanism 5, electrically connected to the pressure sensor 11 and the infrared sensor 14 respectively, for processing signals and controlling the filling process.

[0069] Working principle: First, adjust the height of the filling head 13 with the help of the adjusting mechanism 5. The specific operation is to rotate the crank 18 to make the lead screw 16 rotate, thereby driving the connecting block 17 that cooperates with the lead screw and the lifting plate 15 connected to the connecting block to move up and down. During this process, the second guiding column 19 will pass through the second guiding hole 20 on the lifting plate 15 to play a guiding role and ensure the smooth movement of the lifting plate.

[0070] Next, according to the specific specifications of the filling barrel, adjust the distance between the filling heads 13 with the distance adjusting mechanism. The cross bar 22 of this mechanism is provided with a slidable moving block 23, and the filling heads 13 are installed on the moving block. The distance between the filling heads is changed by the sliding of the moving block on the cross bar to adapt to different filling barrels.

[0071] Filling working stage

[0072] Place the barrel to be filled on the bearing platform 12 of the weighing mechanism 4. At this time, the pressure sensor 11 will collect the initial weight signal of the barrel in real time and transmit it to the processing module 25.

[0073] The lifting cylinder 6 is started to drive the U-shaped frame 7 to descend. During the descent of the U-shaped frame, the first guiding column 8 will slide along the first guiding hole 9 on the adjusting mechanism 5 to ensure the vertical and smooth descent of the U-shaped frame and make the filling head 13 close to the barrel mouth.

[0074] The filling head 13 starts to pour the chemical into the barrel. At the same time, the pressure sensor 11 continuously monitors the total weight change of the barrel and the material, and the infrared sensor 14 real-time detects the height of the liquid level in the barrel.

[0075] The pressure sensor 11 and the infrared sensor 14 will continuously transmit the collected weight signal and liquid level height signal to the processing module 25.

[0076] Filling control and ending stage

[0077] The processing module 25 will perform real-time analysis on the signals transmitted by the pressure sensor 11 and the infrared sensor 14. When both of these signals reach the preset values, that is, when the material weight reaches the set filling volume and the liquid level height also reaches the specified position, the processing module 25 will determine that the filling is complete and issue an instruction to stop the filling head 13 from filling.

[0078] If either the weight signal collected by the pressure sensor 11 or the liquid level height signal collected by the infrared sensor 14 does not meet the preset value, the processing module 25 will issue an instruction to let the filling head 13 continue the filling operation until both signals meet the preset requirements.

[0079] After the filling is completed, the lifting cylinder 6 drives the U-shaped frame 7 to rise and reset. The operator can remove the bucket filled with chemicals and then carry out the next round of filling operation.

[0080] Guiding and Stability Assurance

[0081] During the entire process of the lifting of the U-shaped frame 7, the cooperation between the first guiding column 8 and the first guiding hole 9, as well as the sliding of the lifting plate 15 on the second guiding column 19, jointly ensure that the filling head 13 can perform precise vertical movement, effectively avoiding the situation of deviation.

[0082] The pressure sensor 11 and the infrared sensor 14 form a dual detection mechanism. This design greatly improves the filling accuracy and can effectively prevent problems such as overflow or underfilling.

[0083] Advantages of Modular Structure

[0084] The frame 1, the fixed beam 2, and the fixed cross plate 3 together constitute a stable support structure, providing a reliable foundation for the operation of each module of the equipment.

[0085] The weighing mechanism 4, the adjusting mechanism 5, and the spacing adjusting mechanism all adopt modular design, which makes the maintenance of the equipment more convenient and can also be flexibly adjusted according to different production requirements.

[0086] Beneficial Effects: Dual Detection, Higher Precision

[0087] The pressure sensor 11 and the infrared sensor 14 constitute a dual detection mechanism, which can simultaneously monitor the material weight and the liquid level height. Only when both reach the preset values is it determined that the filling is complete, effectively avoiding underfilling or overflow and greatly improving the filling accuracy.

[0088] Guiding is Stable, Movement is Precise

[0089] The cooperation between the first guiding column 8 and the first guiding hole 9, and between the second guiding column 19 and the second guiding hole 20 plays a good guiding role during the lifting process of the U-shaped frame 7, ensuring the vertical and stable movement of the filling head 13, avoiding deviation, and ensuring accurate filling positions.

[0090] Height and spacing adjustable, strong adaptability

[0091] The adjusting mechanism 5 drives the screw rod 16 to rotate by turning the crank 18, enabling the height adjustment of the lifting plate 15 and the filling head 13 to adapt to filling barrels of different heights; the spacing adjusting mechanism slides the moving block 23 on the cross bar 22 to adjust the spacing of the filling heads 13, adapting to filling barrels of different specifications and increasing the applicable range of the equipment.

[0092] Modular design, convenient and flexible maintenance

[0093] The weighing mechanism 4, the adjusting mechanism 5, the spacing adjusting mechanism, etc. adopt modular design, facilitating equipment maintenance; at the same time, each module can be flexibly adjusted according to different production requirements, enhancing the flexibility and expandability of the equipment.

[0094] High degree of automation, improving efficiency

[0095] The lifting cylinder 6 drives the U-shaped frame 7 to lift, the filling head 13 automatically fills, and the processing module 25 automatically analyzes signals and controls the filling process, reducing manual operation and improving the automation degree and production efficiency of the filling operation.

[0096] Stable structure, reliable operation

[0097] The frame 1, the fixed beam 2 and the fixed cross plate 3 form a stable support structure, providing a reliable foundation for the operation of each module of the equipment, ensuring the overall structural stability of the equipment and reliable operation.
