Description

Technical Field

[0001] The utility model relates to the technical field of organosilicon production, in particular to an organosilicon feeding negative pressure barreling device. Background Art

[0002] In the process of handling and packaging silicone materials, loading and unloading is a key step that directly affects production efficiency, material loss and product purity. Traditional methods of loading and unloading rely on manual operation or simple mechanical assistance, which may cause problems such as uneven loading, residual air in the barrel leading to material oxidation, dusty operating environment, and high labor intensity. These problems are particularly prominent for high-viscosity and easily contaminated materials such as silicone.

[0003] In order to solve the above problems, there are some automated or semi-automated barrel filling equipment on the market, most of which use gravity feeding combined with mechanical vibration to try to improve filling efficiency and reduce residue. However, these devices are often complex in design, have high maintenance costs, and are difficult to accurately control the feeding speed and amount, which can easily cause material waste or stratification of materials in the barrel. In addition, for silicone products that need to maintain a high degree of purity, the open or poorly sealed feeding system in the existing technology is difficult to meet the high cleanliness requirements of dust-free and oxygen-free operations. Summary of the invention

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies in the prior art and provide a silicone barrel filling solution with the purpose of simple structure, convenient operation, good sealing performance, and the ability to effectively reduce material loss and improve work efficiency.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a silicone material unloading negative pressure barrel filling device, including a frame, which is arranged above a barrel feeding belt that conveys packaging barrels, and a lifting and lowering pressure block is provided on the frame directly above the barrel feeding belt, a material storage cavity is provided inside the lifting and lowering pressure block, a material unloading pipe is provided at the bottom of the material storage cavity, a sealing layer is provided on the bottom plate of the lifting and lowering pressure block, a negative pressure pipe is passed through the bottom plate of the lifting and lowering pressure block, and the negative pressure pipe is connected to the negative pressure generator.

[0007] In a preferred solution, flange plates are provided at both the upper and lower ends of the lifting and lowering pressure block, and the negative pressure pipe is passed through the flange plate at the lower part of the lifting and lowering pressure block;

[0008] A guide rod is provided on the upper flange plate of the lifting and lowering pressure block. The guide rod is vertically arranged and the upper end of the guide rod is fixed on the frame.

[0009] In a preferred solution, a threaded barrel is provided on the top of the lifting and lowering pressure block, a motor is provided on the top of the frame, the motor driving shaft is downward and the shaft is connected with a threaded rod, and the threaded rod and the threaded barrel are threadedly connected.

[0010] In a preferred embodiment, an extension rod section is provided at the lower end of the threaded rod, and the extension rod section passes into the storage chamber. A stirring rod is provided on the portion of the extension rod section located in the storage chamber, and a sealing block is provided at the lower end of the extension rod section. The sealing block is vertically aligned with a discharge pipe at the bottom of the storage chamber, and the cross-sectional shape and size of the sealing block are the same as those of the discharge pipe.

[0011] In a preferred solution, an inclined feed pipe is provided on the outer wall of one side of the storage chamber, and a feed valve is provided on the feed pipe.

[0013] The organic silicon material negative pressure barreling device provided by the utility model has the following beneficial effects by adopting the above structure:

[0014] (1) By setting a sealing layer with a variable diameter structure, a close fit with the mouth of the packaging barrel is achieved, which can effectively prevent air from entering the barrel even under negative pressure, greatly reducing the chance of contact between silicone materials and oxygen, reducing the possibility of oxidation, and avoiding dust pollution, thereby improving the purity and stability of the product;

[0015] (2) The integrated negative pressure generator, control panel, proximity switch, regulating valve and other components form a complete automatic control system. The operator can easily adjust the negative pressure and monitor the feeding process through the control panel, realizing intelligent operation, reducing labor intensity and improving production efficiency;

[0016] (3) By utilizing the exquisite coordination between the threaded barrel and the threaded rod, combined with the motor drive, the lifting and lowering of the lifting block is achieved, thereby accurately controlling the material feeding speed and amount, avoiding the uneven feeding and waste in the traditional method, improving the material utilization efficiency and barrel filling accuracy. At the same time, relying on the linked stirring rod, the material is properly stirred during the feeding process, avoiding the agglomeration or stratification of the high-viscosity silicone material in the storage cavity, ensuring the uniform distribution of the barreled material, and further improving the product quality.

[0028] The device construction of the above-mentioned organic silicon feeding negative pressure barrel filling device:

[0029] Frame 1: Made of high-strength steel, it is firmly installed on the ground and is positioned just above the barrel conveying belt 3 that conveys the packaging barrel 2.

[0030] The lifting and lowering block 4 is made of aluminum alloy, and is hollow inside to form a material storage chamber 5. A material discharge pipe 501 is provided at the bottom of the material storage chamber for smooth discharge of the organic silicon material.

[0031] Sealing layer 6: Designed as a variable diameter annular structure, the bottom diameter is smaller than the inner diameter of the barrel mouth, and the top diameter is slightly larger than the inner diameter of the barrel mouth. It is made of rubber or elastic plastic to ensure a close fit with the barrel mouth.

[0032] Negative pressure system: including a negative pressure generator 18, which is connected to the bottom plate of the lifting and lowering pressure block through a negative pressure pipe 17, and can generate sufficient negative pressure to promote the smooth falling of materials.

[0033] Operation process:

[0034] Feeding preparation: open the feed valve 16 , feed the organic silicon raw material into the storage chamber 5 through the feed pipe 15 , and close the feed valve 16 to seal the storage chamber 5 .

[0035] Negative pressure start: start the negative pressure generator 18 through the control panel 20, cooperate with the regulating valve 19, adjust to a suitable negative pressure value, so that a negative pressure state is formed in the storage chamber.

[0036] Material discharge operation: the motor 10 drives the threaded rod 11 to rotate, driving the threaded barrel 9 and the lifting and pressing block 4 to slowly descend. As the lifting and pressing block descends, the sealing layer 6 gradually clings to the mouth of the packaging barrel to form a seal. At the same time, the negative pressure causes the material to evenly fall into the barrel through the discharge pipe 501.

[0037] Material stirring: During the material feeding process, the stirring rod 13 slightly stirs the material storage cavity as the lifting and lowering pressure block descends, ensuring the fluidity and uniformity of the material.

[0038] Stop and clean: When the preset filling volume is reached or the barrel is full, the proximity switch 21 senses and sends a signal to the control panel, automatically stopping the motor and completing the barrel filling. Afterwards, the storage chamber can be emptied and the equipment can be cleaned by lifting the lifting and pressing block.
