Description

Technical Field

[0001] This utility model relates to the field of food preservation film production technology, and in particular to a double vacuum hopper feeding device for food preservation film production. Background Technology

[0002] As a common packaging material for food preservation and item protection, cling film is produced using PVC and other resin powders as core raw materials and a continuous casting process to achieve large-scale production. In this process, the double vacuum hopper feeding device has become the mainstream feeding equipment on the cling film production line due to its unique double-cavity vacuum structure.

[0003] However, PVC and other resin powders are characterized by easy moisture absorption, fine particles, and strong adhesion. In the rainy season or in high-humidity production environments, the powder easily absorbs moisture from the air to form tiny clumps. In the discharge area, due to the cohesive force between powder particles and the adhesion to the wall, an arch-like bridging structure is easily formed. Traditional equipment relies only on simple paddle agitators to prevent clogging, but its agitation range is limited to the middle of the hopper, which cannot effectively break up the clumps and bridging structures. As a result, the machine needs to be stopped for manual unblocking, which greatly reduces the working efficiency of the equipment.

[0004] Therefore, it is necessary to provide a double vacuum hopper feeding device for the production of plastic wrap to solve the above-mentioned technical problems. Utility Model Content

[0005] This utility model provides a double vacuum hopper feeding device for the production of cling film, which solves the problem that the lack of effective anti-clogging function in traditional devices leads to a significant decrease in the working efficiency of the device.

[0007] Preferably, the stirring structure includes a second driving member fixedly mounted on the main body of the device, a first rotating rod mounted on the lower output end of the second driving member, and a first stirring frame fixedly connected to the first rotating rod.

[0008] Preferably, a drive wheel is installed on the upper output end of the second drive component, a belt is provided on the drive wheel, and a driven wheel is provided on the main body of the device. The drive wheel and the driven wheel are connected by belt drive.

[0009] Preferably, a second rotating rod is fixedly connected to the driven wheel, and a second stirring frame is fixedly connected to the second rotating rod.

[0010] Preferably, the vacuum structure includes a vacuum generator disposed on the main body of the device, and a connecting pipe is disposed on the vacuum generator, the other end of which is fixedly connected to the second hopper.

[0013] Compared with related technologies, the double vacuum hopper feeding device for cling film production provided by this utility model has the following beneficial effects: This utility model provides a double vacuum hopper feeding device for the production of cling film. When the device becomes clogged, the controller controls the first driving component, the protrusion, to move in a circular motion. As the protrusion moves, it squeezes the reciprocating rod, which in turn drives the protective component to vibrate the connecting pipe. This device adds a vibration anti-clogging function. The vibration device uses the mechanical force generated by high-frequency, small-amplitude vibration to directly act on the material accumulation area, breaking the adhesion and friction between particles. This method can loosen and decompose agglomerated powder, while breaking up the bridging structure, ensuring that the material flows evenly to the discharge port, avoiding material interruption or surging, thereby improving the working efficiency of the device.

[0020] A drive wheel 302 is installed on the output end above the second drive component 301. A belt 304 is provided on the drive wheel 302. A driven wheel 305 is provided on the main body 1 of the device. The drive wheel 303 and the driven wheel 305 are connected by a belt 304.

[0021] A second rotating rod 306 is fixedly connected to the driven wheel 305, and a second stirring frame 308 is fixedly connected to the second rotating rod 306. The second stirring frame 308 has the function of stirring the raw materials to prevent them from tangling.

[0025] The working principle of the double vacuum hopper feeding device for cling film production provided by this utility model is as follows: When the device becomes blocked, the controller can activate the first drive unit 201. The first drive unit 201 will drive the rotating block 203 to rotate, which in turn will drive the protrusion 203 to rotate. As the protrusion 203 moves, it will compress the reciprocating rod 207, which in turn will drive the protective member 210 to vibrate the connecting pipe 209. The reciprocating rod 207 will then drive the top plate 205 to compress the elastic member 208. When the protrusion 203 rotates to its initial position, the elastic member 208 will use its own elasticity to push the top plate 205 to slide along the guide rod 206, thereby causing the vertical rod 207 to reset. As the first drive unit 201 operates, it will continuously vibrate the connecting pipe 209, thereby clearing the blockage.

[0026] Compared with related technologies, the double vacuum hopper feeding device for cling film production provided by this utility model has the following beneficial effects: When the device becomes clogged, the controller controls the first drive component 201, protrusion 203, to move in a circular motion. As protrusion 203 moves, it squeezes reciprocating rod 207 to move. At the same time, reciprocating rod 207 drives protective component 210 to vibrate connecting pipe 209. This device adds a vibration anti-clogging function. The vibration device can directly act on the material accumulation area through the mechanical force generated by high-frequency small-amplitude vibration, destroying the adhesion and friction between particles. This method can loosen and decompose agglomerated powder, and at the same time break up the bridging structure, ensuring that the material flows evenly to the discharge port, avoiding material interruption or surging, thereby improving the working efficiency of the device.
