[0036] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0037] It should be understood that terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0038] The present invention first analyzes the current pulp molding production process to determine the main reason for the extremely low molding yield of narrow-track pulp molding products.

[0039] like Figure 1 As shown, when the pulp molded product has two or more smooth-appearance cavities, the convex smooth surface between the two smooth-appearance concave surfaces of the cavities is called the runway smooth surface, and the concave rough surface between the two smooth-appearance concave surfaces of the cavities is called the runway.

[0040] like Figure 2 As shown in the figure, narrow runway pulp molding products are determined by the width of the concave rough surface between the two smooth-looking concave surfaces of the cavity and the width-to-depth ratio. That is, when the runway width is less than 8mm, it is considered a narrow runway product regardless of the width-to-depth ratio; when the runway width is greater than 8mm and the width-to-depth ratio is less than or equal to 0.8, it is a narrow runway product. Compared with other ordinary paper-plastic products, narrow runway paper-plastic products often form pulp piles (or bridges) at the reduced runway position due to the continuous adsorption and molding of pulp fibers during the wet blank molding process, resulting in a reduction in the runway position spacing and uneven pulp.

[0041] like Figure 3 As shown, in the subsequent extrusion and dehydration process, due to the existence of slurry accumulation at the narrow runway position, the runway position has the highest strength and the lowest toughness at the same extrusion depth.

[0042] like Figure 4 As shown in the figure, in addition, due to the large thickness of the wet paper-plastic blank and the small size of the corresponding position of the hot pressing upper mold, the mold closing process often causes the phenomenon of slurry pushing. For ordinary products, this phenomenon can be solved by the toughness deformation of the product during the hot pressing process. However, for narrow runway products, due to the large strength and small toughness of the runway position, and the small toughness deformation caused by the small runway (suppressed at the size level), the mold closing process of the hot pressing upper mold and the hot pressing lower mold will directly cause slurry pushing, resulting in tearing of the product runway position and zero yield. This is the main factor leading to the extremely low molding yield of narrow runway pulp molding products.

[0043] In response to this problem, Chinese patent CN109371762B discloses a mold for pulp molded products and a narrow runway process method. It includes at least two independent cavities, the adjacent runway bridging position in the independent cavity is the runway slurry suction cavity unit, and the other part is the non-runway slurry suction cavity unit; a vacuum suction pump is independently set in the non-runway slurry suction cavity unit of each independent cavity. At the same time, a narrow runway process method using the above-mentioned mold is also disclosed, including immersing the slurry suction mold below the slurry liquid level, and the vacuum suction pump in each independent cavity sucks slurry under a negative pressure of -0.15MPa to -0.20MPa; when the slurry at the corresponding position of the non-runway slurry suction cavity unit is saturated, the vacuum suction pump sucks slurry under a negative pressure of -0.10MPa to -0.15MPa. It adopts the method of independent slurry suction at the runway position and the non-runway position to control the fiber bridging phenomenon at the adjacent runway position. However, the above technical solution requires the equipment modification of the slurry suction part of the traditional pulp molding equipment in order to achieve proofing and mass production, and the current process of independent slurry suction in separate chambers is not mature.

[0044] like Figure 5 As shown, the present invention designs a narrow runway product auxiliary forming process, comprising the following steps:

[0045] Step 1: slurry suction molding; Step 2: dehydration molding; Step 3: auxiliary smooth extrusion molding; Step 4: hot pressing molding.

[0046] An auxiliary molding process for a narrow runway product of the present invention is different from a traditional paper-plastic molding process. The core of the present invention is to add an auxiliary smooth extrusion molding process between step two, dehydration molding, and step four, hot pressing molding for narrow runway structure products, that is, the shear force exerted on the edge of the runway during the closing process of the hot pressing upper mold and the hot pressing lower mold is changed into sliding friction force, and a narrow runway molding mold is designed (the convex cavity at the edge of the runway is designed with a larger draft angle) for auxiliary plasticity, and the edge of the narrow runway position is changed into a structure that is conducive to the closing process by closing the narrow runway molding mold with the hot pressing lower mold.
