Description

Technical Field

[0001] The utility model relates to the technical field of food packaging, in particular to an automatic packaging machine. Background Art

[0002] Automatic packaging machines play an important role in the packaging of fried peanuts. They can efficiently perform automatic metering, filling, and sealing operations on fried peanuts. The fast and continuous packaging process greatly improves production efficiency and meets the market's high demand for fried peanuts. Its accuracy ensures the consistent weight of each bag of peanuts and stable product quality. At the same time, automatic packaging machines can adjust parameters according to different needs and adapt to various packaging specifications. Its reliability makes the production process smoother and reduces the occurrence of failures. It also maintains the hygiene of fried peanuts during the packaging process, avoiding contamination caused by human contact, and providing consumers with a safe and reliable product. Automatic packaging machines generally require the following technologies:

[0003] 1. Able to accurately and stably transport materials to be packaged to ensure the continuity of the packaging process;

[0004] 2. Accurately measure the materials to ensure that the amount of material in each package meets the requirements;

[0005] 3. Process packaging materials such as plastic film, paper, etc. into suitable shapes for packaging;

[0006] 4. Effectively seal the package to prevent material leakage and external contamination;

[0007] 5. Realize the automation of the packaging process to improve production efficiency and packaging quality.

[0008] Currently, manufacturers use a variety of equipment and methods to achieve automatic food packaging. In terms of material conveying, common ones include conveyor belts and screw conveyors. The appropriate conveying method is selected according to the characteristics of the material. In terms of metering technology, electronic scales and volumetric meters are used to measure the material. In terms of packaging material forming, the packaging material is processed into the desired shape through heating, pressurization, and stretching, such as bag making and box making. In terms of sealing technology, heat sealing and adhesive sealing are used to seal the package. In terms of automation control, devices such as programmable logic controllers are used to control each operating link of the packaging machine.

[0009] However, the above method has a prominent hardware structure problem. When the equipment is used, it will first screen the peanut raw materials to prevent the packaged peanuts from being too large and causing the product to be unsightly. However, during the screening process, some larger peanut particles may clog the screen, resulting in a reduction in the filtration efficiency of the screen and affecting the progress of the entire production process. To address this problem, the present application proposes a solution and designs a screen with a vibration function. The vibration of the screen makes the previously blocked sieve holes smooth again, and the screen can now screen the peanut particles, improving the screening efficiency of the screen.

[0030] Example

[0031] The technical solution in the embodiment of the present application effectively solves the technical problem that some larger peanut particles may clog the screen during screening, resulting in reduced filtration efficiency of the screen and affecting the progress of the entire production process. The overall idea is as follows:

[0032] In response to the problems existing in the prior art, the utility model provides an automatic packaging machine, including a feeding device 11 and a packaging device 12, the feeding device 11 is located at the right end of the packaging device 12, the automatic packaging machine is also provided with a screening mechanism, including a screen 17, the screen 17 is located inside the feeding device 11, both ends of the screen 17 are fixedly connected to a fixed plate three 18, the lower ends of the two fixed plates three 18 are fixedly connected to a spring 28, the lower ends of the two springs 28 are fixedly connected to a fixed plate four 29, the two fixed plates four 29 are fixedly connected to the inner wall of the feeding device 11, the upper end of the feeding device 11 is fixedly connected to a connecting long plate 27, both ends of the connecting long plate 27 are sleeved with a fixed long rod 13, the lower ends of the two fixed long rods 13 are fixedly connected to the fixed plate three 18, the two The upper ends of the fixed long rods 13 are fixedly connected to the connecting plates 23, and the front and rear ends of the two rotating bevel gears 19 are provided with fixed plates 14. The lower ends of each fixed plate 14 are fixedly connected to the connecting long plates 27. When the screen 17 is blocked, the staff starts the motor 22, and the motor 22 drives the rotating bevel gear 19 to rotate. At this time, the rotating bevel gear 19 drives the meshing bevel gears 26 at the front and rear ends to rotate, and the meshing bevel gears 26 drive the corresponding connecting short rods 30 and sprockets 25 to rotate. Since the chain 21 is engaged with the sprockets 25 at both ends, the two sprockets 25 at both ends drive the rotating column 24 to rotate. When the rotating column 24 rotates, it will drive the rotating plate 20 to rotate. A connecting plate 23 is provided on the trajectory of the rotation of the rotating plate 20, so the rotating plate 20 will press the connecting plate 23 when it rotates.

[0033] The upper end of the connecting long plate 27 is fixedly connected with a U-shaped plate 16, and the U-shaped plate 16 is located at the center point of the connecting long plate 27. The upper end of the U-shaped plate 16 is rotatably connected to the rotating bevel gear 19, and the lower end of the U-shaped plate 16 is fixedly connected to the motor 22. The output port of the motor 22 passes through the U-shaped plate 16 and is fixedly connected to the rotating bevel gear 19.

At this time, the connecting plate 23 is not squeezed, and the two springs 28 pop out to push the screen 17. This reciprocating process achieves the purpose of the screen 17 vibrating up and down. At this time, the larger peanuts no longer block the screen holes. The originally blocked screen holes are made smooth again through the vibration of the screen 17, thereby improving the screening efficiency of the screen 17 and ensuring that the entire packaging process is not affected.

[0035] Working principle:

[0036] When the screen 17 is blocked, the staff starts the motor 22, and the motor 22 drives the rotating bevel gear 19 to rotate. At this time, the rotating bevel gear 19 drives the meshing bevel gears 26 at the front and rear ends to rotate, and the meshing bevel gears 26 drive the corresponding connecting short rods 30 and sprockets 25 to rotate. Since the chain 21 is meshed with the sprockets 25 at both ends, the two sprockets 25 at both ends drive the rotating column 24 to rotate. When the rotating column 24 rotates, it drives the rotating plate 20 to rotate. A connecting plate 23 is provided on the rotation trajectory of the rotating plate 20. Therefore, when the rotating plate 20 rotates, it presses the connecting plate 23. At this time, the connecting plate 23 drives the rotating bevel gear 19 to descend. When the two rotating bevel gears 19 descend, they drive the screen 17 The spring 28 is squeezed, and the rotating plate 20 continues to rotate. At this time, the connecting plate 23 is not squeezed, and the two springs 28 pop out to push the screen 17, and so on, to achieve the purpose of the screen 17 vibrating up and down.
