Description

Technical Field

[0001] This utility model relates to the field of paper product processing technology, and in particular to a paper product humidification device for paper product processing. Background Technology

[0002] Disposable striped cups are a common drinking tool, widely used in homes, offices, and the catering industry. They are typically made of food-grade wood pulp paper and food-grade PE film.

[0003] The specific production process of disposable striped cups is as follows: First, raw materials are prepared, usually coated paper. Then, the coated paper is coated on both sides using a coating machine to increase water resistance and strength. Next, the surface of the coated paper is printed. Then, a slitting machine is used to cut the coated paper into the required cup size. Next, a die-cutting machine cuts it into fan-shaped structural paper pieces and round cup bottom paper pieces. Then, the fan-shaped structural paper pieces and round cup bottom paper pieces are fed into a paper cup forming machine. Through processes such as heating and pressing, the paper pieces are formed into complete finished paper cups.

[0004] Currently, when paper materials are transported for surface printing, the dry processing environment can cause static electricity to form on the paper materials, which in turn affects the subsequent printing quality. Utility Model Content

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figure 1-5 A paper product humidification device for paper product processing includes a humidification rack 1, a base plate 4 below the humidification rack 1, a printing assembly 41 and a guide side plate 7 on the base plate 4, paper raw material 42 passing through the printing assembly 41, a feeding support plate 5 and a receiving support plate 6 on the base plate 4, a feeding roller 51 on the feeding support plate 5, a receiving motor 61 on the receiving support plate 6, a receiving roller 62 on the receiving motor 61, a steam box 11 on the humidification rack 1, a heating wire 12 and an air pump 2 on the steam box 11, a three-way pipe 21 and an air extraction pipe 22 on the air pump 2, an air supply pipe 3 connected to the three-way pipe 21, and a telescopic pipe 31 connected to the air supply pipe 3;

[0028] The telescopic tube 31 is provided with a spray hood 32, the spray hood 32 is provided with a spray nozzle 33, and the spray hood 32 is provided with a pull ring 34.

[0029] The guide side plate 7 is equipped with a guide motor 71, the guide motor 71 is equipped with a guide roller 72, the guide roller 72 is equipped with a baffle plate 73, the baffle plate 73 is equipped with a smoothing layer 74, and the steam box 11 is pre-installed with a water supply pipe to facilitate subsequent water replenishment. The prior art is not shown.

[0030] The printing assembly 41, paper raw material 42, feeding support plate 5, feeding roller 51, receiving support plate 6, receiving motor 61, and receiving roller 62 described in this patent are all commonly used structures in the production and processing of disposable horizontal striped cups. They are existing technologies, and some existing structures are not drawn or labeled, so there is no need to elaborate.

[0031] The humidifier rack 1 has a U-shaped structure. The steam box 11 is located at the top of the humidifier rack 1. The heating wire 12 is embedded in the inner wall of the steam box 11. The heating wire 12 can quickly heat the water in the steam box 11 to a high temperature and boil it to form steam, which is the existing technology.

[0032] The air extraction pipe 22 is located at the lower end of the air pump 2, and the three-way pipe 21 is located at the top of the air pump 2. There is a gap between the air extraction pipe 22 and the water surface preset in the steam box 11 to prevent the air extraction pipe 22 from being immersed in boiling water.

[0033] Air pump 2 can quickly extract steam.

[0034] The air supply pipe 3 and the spray humidifier 32 are a set, and there are two sets symmetrically arranged. The spray humidifier 32 is a diffused hood structure facing the paper raw material 42, so as to achieve a symmetrical steam humidification effect on the paper raw material 42.

[0035] The spray hood 32 has a hollow cavity inside, and the spray nozzles 33 are connected to the hollow cavity of the spray hood 32. There are multiple spray nozzles 33, which can achieve a comprehensive humidification effect on the paper raw material 42.

[0036] The telescopic pipe 31 is a stainless steel corrugated pipe structure, which can only be adjusted in the horizontal direction, while ensuring the effective delivery of steam.

[0037] The pull rings 34 are two symmetrical rings, respectively located on the front and rear outer walls of the spray hood 32, so that fingers can be hooked in and the spray hood 32 can be pulled horizontally for adjustment.

[0038] The smoothing layer 74 is uniformly coated along the inner wall of the baffle plate 73. The smoothing layer 74 is a graphite powder density coating layer, which has excellent smoothness, a flat and durable surface, and improves the smoothness between the baffle plate 73 and the paper raw material 42, thus avoiding wear.

[0039] Working method: Paper raw material 42 is fed horizontally to the left from the feeding roller 51, passes through the printing assembly 41 and is fixedly sleeved on the receiving roller 62. The receiving motor 61 is started to feed and receive the paper raw material horizontally from right to left; (existing technology)

[0040] Before printing, the heating wire 12 and the air pump 2 can be activated. The heating wire 12 will rapidly heat the water pre-stored in the steam box 11 to a high temperature and boil it. The boiling water will generate steam. The activated air pump 2 will quickly draw away the steam through the suction pipe 22. The steam will then be effectively and symmetrically sprayed onto the paper material 42 through the three-way pipe 21, the air supply pipe 3, the telescopic pipe 31, and finally through the spray nozzle 33 on the spray hood 32. The humidified paper material 42 will then enter the printing group 41 for normal printing. This avoids the situation where the paper material 42 dries and generates static electricity due to the dryness of the processing environment, thereby ensuring the subsequent printing quality of the paper product material 42.

[0041] Furthermore, when the humidified paper material 42 is horizontally conveyed to the left towards the printing group 41, the guide motor 71 is started, driving the guide roller 72 and the baffle plate 73 to rotate at a uniform speed. This rotation speed is the same as the rotation speed of the take-up motor 61, ensuring synchronous conveying of the paper material 42. At this time, the paper material 42 will be horizontally and stably guided to the left along the guide roller 72 and the baffle plate 73 into the printing group 41.

[0042] In addition, by hooking the pull ring 34 and pulling the spray hood 32 horizontally, the distance between the spray hood 32 and the paper material 42 can be adjusted horizontally, thereby ensuring the effective humidification distance between the spray hood 32 and the paper material 42.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
