Description

Technical Field

[0001] The invention relates to the technical field of packaging, in particular to an automatic plastic film bagging device. Background Art

[0002] Plastic film is usually made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins, used for packaging and as a coating layer. Plastic packaging and plastic packaging products occupy an increasingly large share in the market, especially composite plastic flexible packaging, which has been widely used in food, medicine, chemical and other fields, among which food packaging accounts for the largest proportion, such as beverage packaging, frozen food packaging, steamed food packaging, fast food packaging, etc. These products have brought great convenience to people's lives.

[0003] Long tubular materials usually refer to materials that are tubular and have a large aspect ratio. The following are several common types of long tubular materials and their applications: 1. Composite long tubes: These long tubular materials are often used in the design and manufacture of hydrogen systems. They are high-strength and lightweight, and use large-diameter steel pipes and carbon fibers as the main raw materials. The design of the composite long tube includes anti-fatigue cracking structure, anti-electrochemical corrosion coating and insulation structure, and is suitable for hydrogen fuel cell commercial vehicles, passenger cars, ships, rail transit and other application scenarios.

[0004] 2. Tubular reactor: This is a continuously operated reactor with a tubular shape and a large aspect ratio. Tubular reactors can be very long. For example, the reactor tube length of propylene dimerization can reach several kilometers. This reactor is suitable for gas phase or liquid phase reactions and has the characteristics of high volumetric efficiency and low back mixing. Common types include horizontal tubular reactors, vertical tubular reactors, coil reactors and U-shaped tubular reactors, which are widely used in gas phase continuous operations in chemical production.

[0005] 3. Steel pipe: Steel pipe is a common long tube material, which can be divided into seamless steel pipe and welded steel pipe according to the production method. Seamless steel pipe is made of high-quality carbon steel or alloy steel, while welded steel pipe is welded by steel plates rolled into a tube shape. Steel pipe is widely used in liquid and gas pressure pipelines, gas pipelines, water pipelines, gas pipelines, heating pipelines, etc.

[0006] These long tubular materials play an important role in different industrial fields, such as energy, chemical industry, construction and transportation.

[0007] In order to protect the above-mentioned long tubular materials from damage during transportation, storage and use, and to improve the management and use efficiency of materials, long tubular materials are usually bagged. However, since long tubular materials are usually made of metal materials, such as steel pipes, aluminum pipes, etc., although these materials have certain strength, their rigidity may be affected under conditions with a large aspect ratio. For example, when the aspect ratio of a steel pipe is very high, it may not be rigid enough due to its own bending or twisting, and thus it is impossible to bag the above-mentioned long tubular materials in the form of traditional cantilever lifting, which affects the quality of the long tubular materials.

In order to automatically open the opening of the plastic film 5, the upper suction cup assembly 1-5 is located above the winding end of the plastic film 5, and the lower suction cup assembly 1-4 is located below the winding end of the plastic film 5. The lower suction cup assembly 1-4 and the upper suction cup assembly 1-5 are arranged relative to each other.

[0028] In order to make the overall structure of the holding mechanism 1 compact and reduce the space occupied, the moving bearing plate 1-2 is arranged in an "L" shape.

In order to ensure the stability of the overall structure of the upper and lower drive assembly 1-1, the upper and lower drive member mounting plate 1-1-1 can also be designed to be "L" shaped.

[0029] The automatic centering assembly 1-3 in the present invention comprises an "L"-shaped automatic centering mounting plate 1-3-1, a transverse moving driving member 1-3-2, a transverse moving driving rod 1-3-3, and a transverse moving connecting block 1-3-4, wherein the transverse moving driving rod 1-3-3 is mounted on the output end of the transverse moving driving member 1-3-2, the transverse moving driving member 1-3-2 is a motor, the transverse moving driving rod 1-3-3 is a screw rod, the transverse moving connecting block 1-3-4 is mounted on the transverse moving driving rod 1-3-3, the automatic centering mounting plate 1-3-1 is mounted on the transverse moving connecting block 1-3-4, and transverse moving slide rails 1-3-5 are respectively provided on both sides of the transverse moving driving rod 1-3-3, a transverse moving slider 1-3-6 is slidably mounted on the transverse moving slide rail 1-3-5, and the automatic centering mounting plate 1-3-1 is also mounted on the transverse moving slider 1-3-6.

[0030] In order to facilitate the installation of the plastic film 5, the above-mentioned automatic centering mounting plate 1-3-1 is installed with a plastic film support rod 1-3-7 which is arranged horizontally for supporting and rolling up the above-mentioned plastic film 5. The plastic film support rod 1-3-7 can be rotatably installed on the above-mentioned automatic centering mounting plate 1-3-1 through rolling parts such as bearings, so as to retract and release the plastic film 5 and realize the bagging operation of the long tubular material.

Figure 7 As shown, it is a schematic diagram of the opening process of the plastic film 5, which is mainly divided into three parts, namely, the main area 5-1 of the plastic film, the flat area 5-2 of the plastic film, and the plastic film expansion area 5-3. When the main area 5-1 of the plastic film 5 passes through the flat area 5-2 of the plastic film, under the action of the clamps 3-5 at the front end of the bagging Y-direction moving driving component 3-4, the number of the clamps 3-5 is 4, which can just clamp the four corners of the plastic film expansion area 5-3 to form the plastic film expansion area 5-3. After the opening is formed, the bagging process is realized by dragging the bagging mechanism 3. In this process, the present invention can suck and hold the plastic film flat area 5-2 up and down through the lower suction cup 1-4-1 and the upper suction cup 1-5-1 to realize the holding and forming state after the plastic film is cut.

[0032] The above-mentioned cutting mechanism 2 in the present invention includes a cutting mechanism bracket 2-1, an upper cutting component 2-2 and a lower cutting component 2-3.

The upper cutting component 2-2 includes a serrated upper cutting blade 2-2-1, and a pressing rubber strip 2-3-1 is provided at the lower cutting component 2-3. During operation, the pressing rubber strip 2-3-1 is pressed against the flattening area 5-2 of the plastic film. After pressing, the upper cutting component 2-2 continues to descend, and then the upper cutting blade 2-2-1 is released from the plastic film 5 and completely cut off, and then the upper cutting component 2-2 moves to its original position.

The rubber-coated electric roller 4-5-2 is installed on the electric roller support frame 4-5-1.

[0034] The present invention provides an automatic plastic film bagging device. When the bagging mechanism 3 grasps the four holding corners of the plastic film 5 when it is opened, the bagging mechanism 3 starts to move in the X direction, that is, the length direction of the long tubular material, and bag it. When the long tubular material is bagged from 0 to the total length L, assuming that there is a rubber-coated electric roller 4-5-2 at 1 / 4L, the electric roller driving member 4-5-3, that is, the cylinder, needs to be retracted to pull the rubber-coated electric roller 4-5-2 down to achieve an avoidance action on the bagging mechanism 3; when the bagging mechanism 3 passes 1 / 4L, the rubber-coated electric roller 4-5-2 needs to be lifted up under the drive of the electric roller driving member 4-5-3, and the rubber-coated electric roller 4-5-2 starts to run. During this process, it is necessary to ensure that the linear speeds of the bagging mechanism 3 and the rubber-coated electric roller 4-5-2 are equal, so as to reduce the probability of the plastic film being broken and thereby ensure the bagging quality.
