Description

Technical Field

[0001] The invention relates to the technical field of paper production and processing, in particular to a processing method and a device for environmentally friendly food card paper. Background Art

[0002] In the food packaging industry, cardboard is an important packaging material and is widely used in the packaging and labeling of various foods. However, in the existing cardboard production and processing technology, there are still some problems that need to be solved.

[0003] First, the traditional cardboard cutting method often adopts a single-layer or a small number of multi-layer cutting methods. This cutting method is not only inefficient, but also difficult to ensure the consistency of cardboard size. Since each layer of cardboard may be subjected to different cutting forces during the cutting process, the cardboard size will be deviated, affecting the subsequent packaging effect and product quality.

[0004] Secondly, the existing cardboard packaging process mostly relies on manual operation, which is not only time-consuming and labor-intensive, but also prone to errors. When placing the packaging box manually, it is often difficult to accurately control the position of the packaging box, resulting in the cardboard not being able to fall accurately into the packaging box, increasing the failure rate and waste of packaging.

[0005] In addition, cardboard needs to go through multiple processes during processing, such as drying, coating and laminating, winding and quality inspection, sterilization and disinfection, etc. The degree of automation of these processes is not high, and often requires a lot of manual participation, which not only increases production costs, but also reduces production efficiency. Summary of the invention

[0053] The specific processing method steps of the present invention are:

[0054] dry:

[0055] The base paper is sent to the hot air furnace and dryer for drying to remove excess moisture from the paper and improve the stability and processing performance of the paper.

[0056] Coating and lamination:

[0057] Environmentally friendly waterproof coatings are coated on both sides of the dried semi-finished paper.

[0058] The coated paper is laminated by a laminating machine and a pressure roller to enhance the strength and waterproof performance of the paper.

[0059] Rolling and quality inspection:

[0060] The processed paper is sent to the winding mechanism for winding, which is convenient for subsequent processing.

[0061] At the same time, the paper is quality inspected by quality inspection agencies to ensure that the product quality meets the standards.

[0062] Sterilization and disinfection:

[0063] The rolled paper is sterilized and disinfected to ensure the safety and hygiene of food paper.

[0064] Cutting and stacking:

[0065] The sterilized paper is cut to the required size.

[0066] The cut paper is stacked on the conveyor belt, ready for the next step of cutting and packaging.

[0067] Cutting and Packing:

[0068] Precisely cut the stacked paper to obtain cardboard with specific size and shape.

[0069] Package the cut cardboard for storage and transportation.

[0070] Working process of the cutting and packaging mechanism of the present invention

[0071] The conveyor belt 1 runs on the conveyor belt support 2 to transport the stacked paper to the cutting area, that is, the end of the paper extends to the distance of the upper end of the sliding base 4, and the cutting blade 19 moves downward to cut a stack of cardboard of a fixed size. During cutting, the sliding base 4 is fixed, and only when the belt 6 is pulled, the sliding base 4 will move backward. Since the belt 6 is driven by the pulley 7, and the pulley 7 is driven by the rotating arm 14, specifically, the transmission motor 28 drives the rotating shaft 12 to rotate clockwise, and the rotating shaft 12 drives the rotating sleeve 11 to rotate, and the rotating sleeve 11 rotates to drive the rotating arm 14 to rotate. When the rotating arm 14 touches the stop pin 8, the pulley 7 starts to rotate, so the cutting of the cardboard is completed before the rotating arm 14 contacts the stop pin 8.

[0072] After the cutting is completed, the pulley 7 starts to rotate after the rotating arm 14 touches the stop pin 8, and the sliding base 4 is pulled backward by the belt 6. When the rotating arm 14 encounters the wedge-shaped guide block 31, the rotating arm 14 rotates and also makes an axial movement sliding along the rotating shaft 12 inward, causing the rotating arm 14 to disengage from the stop pin 8. Since the sliding base 4 is acted upon by the first compression spring 5, the sliding base 4 will quickly rebound and withdraw to the position where it was during cutting. The sliding base 4 moves from backward movement to rebound and withdraws forward in an instant, so the cut paper jam on the upper side of the sliding base 4 will fall from the sliding base 4 due to the action of inertia and fall to the position on the upper side of the bottom plate 20 behind the cutting base 3, where a packaging box can be placed. Then, the cut paper jam will automatically fall into the interior of the packaging box, and the push rod 23 can automatically and accurately push the packaging box from the bottom plate 20 on the side of the arc-shaped guide bracket 16 to the card The position where the paper falls does not need to be placed manually, so as to avoid the problem that the jammed paper cannot be accurately put into the box due to the inaccurate placement of the packaging box. There are positioning plates 24 and push plates 25 on both sides of the position where the jammed paper falls from the sliding base 4, and there is a rear baffle 21 on the rear side of the jammed paper. When the sliding base 4 rebounds back to its original position, the rotating arm 14 is just located at the rear side of the push plate 25. When the rotating arm 14 moves axially, it will push the push plate 25 to move inward, and the front baffle 27 located on the push plate 25 will be located at the front side of the jammed paper, resulting in the jammed paper cannot move with the sliding base 4, thereby ensuring that the jammed paper will fall from the space surrounded by the positioning plate 24, the push plate 25, the rear baffle 21 and the front baffle 27, which plays a role in positioning when falling. In addition, the push plate 25 and the front baffle 27 can prevent the jammed paper from scattering, and the jammed paper can fall into the packaging box more neatly. After the jammed paper falls into the packaging box, it can be taken away manually for packaging.

[0073] When the paper jam is finished falling, the rotating arm 14 will separate from the wedge-shaped guide block 31, and due to the action of the second compression spring 15, the rotating arm 14 will return to the original position during cutting, that is, the rotating arm 14 does not move axially and does not contact the stop pin 8. When the rotating arm 14 returns to its original position, the push plate 25 will also be affected by the third compression spring and return to its original position to prevent the front baffle 27 from blocking the end of the sliding base 4 and affecting the next backward movement of the cut paper jam. When the sliding base 4, the rotating arm 14 and the push plate 25 return to their initial state, the conveyor belt will once again transport the stacked paper to the upper end of the sliding base 4 for the next cutting. The above actions are repeated to realize the process of processing the paper jam.

[0074] The present invention can use products in the prior art when processing cardboard, such as drying, coating and compounding, winding and quality inspection, sterilization and disinfection, cutting and stacking. The present invention adopts a method of stacking many layers of larger paper and then cutting many layers at one time during cutting. This overall cutting can better ensure the consistency of the size of the cardboard, and the processing efficiency is also higher. The stacked cardboard after cutting is neat in itself, and there is no need to specially organize it, which is convenient for boxing and will not be scattered.

[0075] The preferred implementation modes of the present application are described in detail above, but the present application is not limited to the above implementation modes, and various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present application.
