As a widely used chemical product, it can be used as a plasticizer and solvent for acetate fiber, nitrocellulose, etc. It also has a plasticizing effect on natural rubber and synthetic rubber, and does not affect the vulcanization operation. As an important chemical raw material, the use of glyceryl triacetate in the food, cosmetics, medicine and dye industries has been developed. In the food industry, glyceryl triacetate has low toxicity and can be used as a mild fungicide for vegetables, fruits, animal glue and synthetic glue. It can also be used as a food additive.
[0003] At present, after the preparation of triacetin, it needs to be placed in a sealed storage tank to prevent oxidation. When it is used or transported, it is transported out of the storage tank and packaged into storage barrels for transportation. However, triacetin is easy to be blocked in the pipeline during transportation. Moreover, the existing packaging method generally relies on manual filling of the product into the storage barrel and then sealing it. During the manual filling process, the amount of product in the storage barrel is inconsistent, and standard packaging cannot be performed.

An electric slider is connected to the two electric slide rails 18 for relative sliding. The support plate 19 is arranged between the two electric slide rails 18 and is fixedly connected thereto.
[0036] See also Figure 3 and Figure 4 The rotating part of the electric telescopic rod 20 is connected and fixed to the bottom surface of the support plate 19, the rotating motor 21 is installed on the telescopic end of the electric telescopic rod 20, the electric suction cup 22 has a sensor and is rotatably connected to the rotating shaft of the rotating motor 21 through a mounting seat, and each electronic control component in the capping mechanism is electrically connected to the controller 1 through a wire. Example 2
[0037] See also Figure 3-6 The specific structure and implementation method are as shown in implementation 1, except that: in order to prevent the material from condensing and clogging in the diversion group during the diversion process, affecting the filling effect, the diversion group is provided with an insulation box 23, see Figure 5 The insulation box 23 has a water inlet on the upper part of the box body and a reflux port on the bottom. The water inlet is connected to the water outlet pipe of the water storage tank 7 and the water inlet of the outer pipe 5 of the feed pipe through a three-way structure. The reflux port is also connected to the connecting pipe of the reflux water pump 8 and the reflux pipe of the outer pipe 5 of the feed pipe through a three-way pipe.
[0038] In order to ensure the filling effect and prevent the storage tank from shifting, Figure 6It can be seen that a clamping component 24 is installed on the filling gantry 13. The number of the clamping components 24 is two groups, which are respectively arranged on the inner sides of the two legs of the filling gantry 13. The clamping component 24 consists of a clamping plate and an electric telescopic clamping rod. The clamping plate is an annular structure, and the curvature of its inner wall is matched with the curvature of the outer wall of the storage barrel. The telescopic end of the electric telescopic clamping rod is fixed at the midpoint of the outer wall of the clamping plate, and the base is connected to the legs of the filling gantry 13. The electric telescopic clamping rod is also connected to the control through a wire.
[0039] When in use, the material is transported to the storage tank 2 for storage and standby, the controller 1 turns on the electric heating tube 3 for preheating and insulation, the temperature sensor 4 monitors the temperature of the insulation solution in real time to ensure that the temperature is within the preset range, and the water in the water storage tank 7 is also heated to the preset temperature value. When it is to be transported, the warm water in the water storage tank 7 enters the cavity between the inner tube 6 and the outer tube 5 and the insulation box 23, and preheats the inner tube 6, the main pipe 9 and the branch pipe 10 to prevent the solution from condensing and clogging in the pipe. At the same time, after reaching the preset time, the reflux water pump 8 draws the cooled warm water back into the water storage tank 7 for heating treatment.
[0040] After preheating, the worker places the empty barrel on the conveyor belt of the workbench 12, and the conveyor belt transports the storage barrel forward. When it reaches the filling gantry 13, the sensor probe 15 transmits real-time information to the controller 1. The controller 1 turns off the conveying motor to make the storage barrel in the corresponding position, and then controls the clamping rod of the clamping component 24 to extend and retract to clamp and position the storage barrel.
[0041] After positioning, the controller 1 opens the discharge solenoid valve and the suction pump 11 on the storage tank 2 in turn to feed the material. The solution passes through the inner tube 6, the suction pump 11, the main pipe 9, and the branch pipe 10 in turn, and then enters the storage barrel through the filling head of the filling head group 14. The weight sensing plate 16 senses and detects the weight of the storage barrel in real time. When the weight in the barrel reaches the set value, the No. 1 filling head and the No. 2 filling head are controlled to close, and the No. 3 filling head completes the remaining filling amount and transmits the information to the controller 1.
[0042] After the filling is completed, the controller 1 controls the conveyor belt to move the storage barrel to one side of the capping placement table 17 and then stops. At this time, the electric telescopic rod 20 is started to extend and retract, thereby driving the electric suction cup 22 to contact the cap on the capping placement table 17. After the sensor of the electric suction cup 22 senses it, it sucks the cap, and then the lid is moved to the upper end of the storage barrel through the movement and coordination of the electric telescopic rod 20 and the electric slide rail 18. The lid is lowered to the upper end of the storage barrel through the electric telescopic rod 20 and contacts with the upper end of the storage barrel, and then the lid is driven to rotate through the rotation, and is threadedly connected through the internal thread of the lid and the external thread on the outside of the storage barrel. Then the electric suction cup 22 is closed and the lid is loosened to complete the capping operation.
[0043] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
