Description

Technical Field

[0001] The invention relates to the technical field of food packaging paper production, in particular to a wax coating, flexible continuous winding system and a manufacturing method for food packaging paper. Background Art

[0002] Food packaging paper is a packaging product made of pulp and paperboard as the main raw materials. It needs to meet the requirements of non-toxicity, oil resistance, waterproof and moisture-proof, sealing, etc., and meet the food packaging safety requirements. Food packaging paper is in direct contact with food, and most of its packaging is food that is directly eaten, so the most basic requirement for food packaging paper is that it must meet the requirements of food hygiene. Secondly, according to the different requirements for the use of food packaging paper, it must also meet the relevant technical standards.

[0003] Reference patent publication number "CN112176768B" discloses a food packaging waxing base paper processing system and process, including a reeling device and a waxing box arranged in sequence, a preheating component is arranged at the feed inlet of the waxing box, a cooling component is arranged at the discharge port, and a stretching component is also arranged in the waxing box, and the stretching component is located between the preheating component and the cooling component.

[0004] This patent improves the wax coating effect while reducing the possibility of base paper breakage. Waxing equipment is often used when waxing food packaging paper. Existing wax coating equipment mostly uses a stick coating method to complete the waxing process of food packaging paper. Roller coating is to fill the wax into a storage box, and a rotating roller is arranged under the storage box, so as to complete the wax coating when the food packaging paper moves. However, since the molten wax is in the storage box and contacts the rotating roller through the action of gravity, the fluidity of the wax in the molten state is relatively poor and the factor of gravity distribution makes the contact between the surface of the rotating roller and the wax inconsistent. The good contact between the wax and the rotating roller gradually decreases from the middle of the rotating roller to the two sides, especially at the edges on both sides, which makes it difficult to achieve an ideal covering effect at the edges of the food packaging paper during waxing. Problems of missing coating and uneven waxing may occur, which are more obvious when the width of the food packaging paper is larger. Summary of the invention

[0056] The present invention also discloses an operation method of a wax coating and flexible continuous winding system for food packaging paper, which specifically comprises the following steps:

[0057] Step 1: Loading: Install the rolled food wrapping paper onto the unwinding assembly 9, and pass it over the flat plate 3 after passing through the auxiliary roller 10, and finally fix the food wrapping paper into the rewinding mechanism 2.

[0058] Step 2: Position adjustment: According to the size of the food wrapping paper, the positions of the two edge rollers 533 are adjusted by adjusting the assembly 6, so that the two edge rollers 533 are aligned with the edges of the food wrapping paper, and the upper and lower gaps between the edge rollers 533 and the food wrapping paper are adjusted at the same time, and the hydraulic cylinder 64 is started to move the drive motor 58 upward or downward, thereby driving the edge roller assembly 53 to move upward or downward, thereby adjusting the size of the gap between the edge rollers 533 and the food wrapping paper, and in addition, the adjustment motor 65 is started to rotate the driving gear 66, and the driving gear 66 rotates and transmits it to the driven gear 67, and the driven gear 67 rotates and drives the bidirectional threaded rod 61 to rotate, thereby making the left and right receiving boxes 531 approach or move away from each other, that is, the positions of the two edge rollers 533 are changed, so that the edge rollers 533 are aligned with the edges of the food wrapping paper.

[0059] Step 3: Waxing: Load the molten wax into the wax storage box in the main wax coating mechanism 4, the wax contacts the main wax coating roller, and at the same time, the wax enters the cache box 56 through the conveying pipe 55, and the wax is spread in the cache box 56 through the paving assembly 8, start the drive motor 58 and the main wax coating mechanism 4, the drive motor 58 works and drives the drive shaft 52 to rotate, the drive shaft 52 rotates and drives the left and right edge rollers 533 to rotate, and while the drive shaft 52 rotates, it drives the eccentric wheel 87 to rotate, the eccentric wheel 87 rotates and contacts the push plate 86, and pushes the push plate 86 to move, and then the paving frame 83 is moved through the second connecting rod 85 and the inner plate 82, and under the action of the elastic force of the reset spring 84, the paving frame 83 reciprocates back and forth inside the cache box 56, so that the wax entering the cache box 56 is spread, the wax flows into the extension bin 532 and contacts the edge roller 533, and then adheres to the edge roller 533, the edge roller 533 rotates and carries the wax to rotate together.

At the same time, the main scraper assembly and the edge scraper assembly are used to adjust the thickness of the wax on the main wax coating roller and the edge roller 533. Then, the visual sensor 742 is used to detect the distance between the scraper 73 and the edge roller 533. When the distance does not match the preset value, the input motor 72 is started to rotate the scraper 73, thereby adjusting the distance between the scraper 73 and the edge roller 533. In addition, while the drive shaft 52 is rotating, its The two limit bars on the driving shaft 52 contact with the rocker arm 745 in turn. When the limit bars contact with the rocker arm 745, the rocker arm 745 is pushed to rotate, and the sponge on the rocker arm 745 contacts with the lens of the visual sensor 742, thereby wiping the lens. In addition, with the cooperation of the middle rod 744, the rocker arm 745 swings back and forth, thereby preventing the hot air carried by the wax from blurring the lens of the visual sensor 742. At the same time, the thickness of the wax on the main wax coating roller and the edge roller 533 are adjusted respectively by the main scraper assembly and the edge scraper assembly 74.

[0061] Step 5: wax coating: start the reeling mechanism 2 and the unwinding assembly 9 to move the food wrapping paper, and then let the wax on the main wax coating roller and the edge roller 533 adhere to the food wrapping paper, thereby completing the wax coating operation.
