Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical equipment, in particular to an automatic valve opening and unloading device for a barrel. Background Art

[0002] In the pharmaceutical manufacturing process, unloading devices are often used to transfer intermediate products or finished products. The existing unloading devices have the following defects in the actual production process:

[0003] 1. The unloading of the barrel is usually done manually, and the butterfly valve at the bottom of the barrel needs to be opened manually to unload the material. The degree of automation is low and it is time-consuming and labor-intensive.

[0004] 2. During the unloading process, in order to prevent the material from remaining in the barrel, it is necessary to manually hit the barrel with a hammer to separate the material from the inner wall of the barrel. This is not only time-consuming and laborious, but also difficult to control the hitting force. If the hitting force is too light, the material cannot be shaken away from the inner wall of the barrel, and if the hitting force is too heavy, it is easy to damage the barrel.

[0005] 3. During the unloading process, the material is often not discharged smoothly due to the low air pressure in the barrel, and manual assistance is required;

[0006] 4. During the unloading process, the sealing performance between the material barrel and the discharge pipe is not strong, and the material leakage is serious.

[0007] 5. The unloading weight cannot be weighed automatically and needs to be weighed manually.

[0008] In summary, the existing unloading devices are labor-intensive and inefficient. Therefore, how to provide an automatic valve opening unloading device for a barrel is an urgent problem to be solved by those skilled in the art. Utility Model Content

DETAILED DESCRIPTION

[0021] The utility model is described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] See alsoFigure 1 - Figure 2 , an embodiment provided by the present utility model:

[0023] An automatic valve-opening discharging device for a material barrel, comprising a base 1, a material barrel 3, a discharging pipeline 8, an automatic valve-opening mechanism and a discharging control system. A weighing system is arranged inside the base 1. The material barrel 3 is placed on the weighing system. The automatic valve-opening mechanism is provided with a butterfly valve 4. The butterfly valve 4 is fixedly connected to the lower discharging end of the material barrel 3. The lower part of the butterfly valve 4 is fixedly and hermetically connected to the discharging pipeline 8 through a clamp 6. One side of the discharging pipeline 8 is fixedly connected with a breathing valve 9 through a pipeline. The breathing valve 9 is an externally purchased part with a model of Φ38*K50.5, which is used to filter air supplement and balance the air pressure inside and outside the material barrel 3 and the discharging pipeline 8, so that the materials in the material barrel 3 can smoothly discharge from the discharging pipeline 8 without manual assistance. A material barrel hammering mechanism is fixedly arranged beside the base 1.

[0024] Among them, the automatic valve-opening mechanism comprises a butterfly valve 4 and a rotary cylinder 5. The rotary cylinder 5 is fixedly installed on the base 1. The output end of the rotary cylinder 5 is fixedly connected to the valve control end of the butterfly valve 4. The rotary cylinder 5 is connected to the discharging control system.

[0025] Among them, the weighing system comprises four weighing modules 2. The weighing modules 2 are respectively located at the four corners of the base 1 and fixedly connected to the base 1. The four weighing modules 2 respectively support the four feet 301 of the material barrel 3. The weighing modules 2 are externally purchased parts with a model of SWB505-MM220-SS-C3, which are used to automatically calculate the discharging weight.

[0026] Among them, an inflatable sealing ring 7 is arranged inside the clamp 6 to prevent materials from leaking during discharging. The inflatable sealing ring 7 is connected to an external air source through a valve.

[0027] Among them, the material barrel hammering mechanism comprises a column 10 and a cylinder 12. A mounting seat 11 is fixedly connected to one side of the middle part of the column 10 close to the material barrel 3. The mounting block 11 is hinged to the bottom of the cylinder 12. The top of the column 10 is hinged to a moving arm 13. A hinge seat 14 is fixedly connected to one side of the middle part of the moving arm 13 close to the cylinder 12. The piston rod end of the cylinder 12 is hinged to the hinge seat 14. A pneumatic hammer 15 is fixedly connected to the end of the moving arm 13. The discharging control system is connected to the cylinder 12 and the pneumatic hammer 15 for control.

[0028] When the material bucket 3 needs to discharge materials, use a forklift or an AGV to place the material bucket 3 on the weighing system. The weighing module 2 weighs and records the total weight of the material bucket 3 before discharging. Then, fixedly connect the butterfly valve 4 and the discharge pipeline 8 through a clamp 6. The inflatable seal ring 7 is inflated and expanded to seal the connection between the butterfly valve 4 and the discharge pipeline 8, ensuring that the materials do not leak during the discharging process. Fix the output end of the rotary cylinder 5 to the valve control end of the butterfly valve 4. The discharge control system drives the rotary cylinder 5 to rotate 90° to open the butterfly valve 4, and the materials are discharged through the discharge pipeline 11, realizing the function of automatically opening the valve for discharging. At the same time, the discharge control system drives the cylinder 12 to act, pushing the moving arm 13 to drive the pneumatic hammer 15 to move towards the material bucket 3. When the pneumatic hammer 15 is close to the wall of the material bucket 3, the cylinder 12 stops acting to prevent the pneumatic hammer 15 from continuing to move forward and damaging the material bucket 3. The pneumatic hammer 15 starts to work under the action of the discharge control system, continuously and equally amplitude knocking on the wall of the material bucket 3 to vibrate the materials remaining on the inner wall of the material bucket 3 away from the inner wall of the material bucket 3, ensuring that no materials remain during the discharging process. After the discharging is completed, under the action of the discharge control system, the pneumatic hammer 15 stops knocking, and the piston rod of the cylinder 12 contracts to drive the moving arm 13 and the pneumatic hammer 15 away from the material bucket 3. At the same time, the rotary cylinder 5 closes the butterfly valve 4, the inflatable seal ring 7 cuts off the air and contracts, loosens the clamp 6 to disconnect the butterfly valve 4 from the discharge pipeline 8, and then loosens the connection between the rotary cylinder 5 and the butterfly valve 4. The weighing module 2 weighs and records the total weight of the material bucket 3 after discharging. Subtract the total weight of the material bucket 3 after discharging from the total weight of the material bucket 3 before discharging to obtain the discharging weight. Finally, use a forklift or an AGV to transport the material bucket 3 away and enter the next cycle.
