Description

Technical Field

[0001] This invention relates to the field of electronic cigarette cartridge technology, specifically a method for manufacturing a pulp heating core with oil-wicking cotton. Background Technology

[0002] Electronic cigarettes are mainly used for smoking cessation and as a substitute for cigarettes. They work by heating up an atomizing coil to generate smoke from the oil on the wicking cotton, which the user then inhales.

[0003] Existing disposable and oil-filled e-cigarette cartridges require multiple layers of oil-wicking cotton to cover the heating wire, and involve complex assembly of components such as the heating wire, oil-wicking cotton, and metal support. This results in low processing efficiency, inconsistent oil conductivity, and significant differences in taste. Ceramic heating cores, on the other hand, pose a significant risk of oil leakage. Therefore, this invention presents a method for manufacturing a pulp heating core with oil-wicking cotton to solve the aforementioned problems. Summary of the Invention

[0004] The purpose of this invention is to provide a method for manufacturing a pulp heating core with oil-wicking cotton, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a method for manufacturing a pulp heating core with oil-wicking cotton, comprising the following steps: Step S1: Making the heating core: Wrap the heating element around the elongated cylindrical mold core with negative pressure liquid absorption holes and fix its position. Wrap oil-guiding cotton around the surface of the mold core and the heating element, and put fastening collars on both ends for later use. Step S2: Prepare the suspension slurry: Add water to the pulp and binder to prepare a suspension slurry with a concentration of 0.5%-3%; Step S3, Quantitative Suspension Slurry: Install the mold core covered with oil-wicking cotton onto the conveying device, send it into the negative pressure suction connection port and the mold sleeve working area, inject quantitative suspension slurry through the metering pump, turn on the negative pressure suction pump to remove excess water, and ensure pressure balance. Step S4, core baking and demolding: Open the mold sleeve, transfer the mold core carrying wet pulp to the pre-baking area, connect the mold core to another high-temperature negative pressure suction system, protect the surface of the wet pulp with a mesh breathable mold sleeve, introduce hot air and simultaneously open the negative pressure suction to form semi-wet pulp. Remove the mold core carrying semi-wet pulp from the mold sleeve and convey it to an open area. Use a robotic arm to remove the mold core from the conveying device and send it into a continuous sintering oven. Step S5, Sintering and Demolding: After baking in the sintering oven, the adhesive is fully cured. After being output from the sintering oven, it is rapidly cooled to separate the mold core from the product. After removing the mold core, a heating core integrating oil-conducting cotton, heating wire, and solidified pulp is obtained.

[0006] In a further embodiment, in step S1, the heating element is a spiral heating wire or a heating plate.

[0007] In a further embodiment, in step S1, the oil-wicking cotton is wrapped in 1 to 3 layers.

[0008] In a further embodiment, in step S2, the pulp is at least one of cotton pulp, red pine pulp, and bamboo pulp, and the binder is at least one of guar gum and sodium alginate.

[0009] In a further embodiment, in step S4, when forming semi-wet pulp, it is necessary to remove more than 60% of the moisture from the wet pulp.

[0010] In a further embodiment, in step S5, the moisture content of the semi-wet slurry needs to be reduced to below 1% after sintering.

[0011] In a further embodiment, after removing the mold core in step S5, excess edge material needs to be trimmed.

[0012] Compared with the prior art, the beneficial effects of the present invention are: the present invention only requires the following process: making a heating core → preparing a suspension slurry → quantitatively dispensing the suspension slurry → baking and demolding the mold core → sintering and demolding. The above process can produce a heating core integrating oil-conducting cotton, heating wire, and solidified slurry. The manufacturing process is simple, and subsequent filling with e-liquid and packaging are all that is needed, which greatly reduces the assembly difficulty and improves product stability and production efficiency.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Please see Figure 1-2This invention provides a technical solution: To address the shortcomings of existing technologies where e-cigarette cartridges require multiple layers of oil-wicking cotton to cover the heating wire, and necessitate complex assembly of components such as the heating wire, oil-wicking cotton, and metal support, resulting in low processing efficiency, large variations in product oil conductivity, and significant differences in taste, this invention designs a method for manufacturing a pulp heating core with oil-wicking cotton. The implementation steps are as follows: Making the heating element: Wrap the spiral heating wire or heating element around the long cylindrical mold core with negative pressure liquid absorption holes and fix it in place; Wrap 1 to 3 layers of oil-wicking cotton around the mold core and heating wire, and attach fastening rings to both ends for later use; Preparation of suspension slurry: Mix at least one of cotton pulp, red pine pulp, and bamboo pulp with binders such as guar gum and sodium alginate, and add water to prepare a suspension pulp with a concentration of 0.5%-3%. Quantitative suspension slurry: Install the mold core covered with oil-wicking cotton onto the conveying device and send it into the negative pressure suction connection port and the mold sleeve working area; Inject a fixed amount of suspension slurry using a metering pump, turn on a negative pressure suction pump to remove excess water, and ensure pressure balance. Baking and demolding of the mold core: Open the mold sleeve and transfer the mold core carrying wet pulp to the pre-baking area. Connect the mold core to another high-temperature negative pressure suction system and protect the surface of the wet pulp with a mesh breathable mold sleeve. Introduce hot air and simultaneously open the negative pressure suction to remove more than 60% of the moisture in the wet pulp, forming semi-wet pulp with good shape retention and rigidity. Remove the mold core carrying semi-wet pulp from the mold sleeve and convey it to an open area. Use a robotic arm to remove the mold core from the conveying device and send it into a continuous sintering oven. Sintering and demolding: After baking in a sintering oven, the moisture content in the semi-wet slurry is reduced to below 1%, and the adhesive is fully cured. After being removed from the oven, it is rapidly cooled to separate the mold core from the product. After removing the mold core, the excess edge material is trimmed to obtain the finished heating core that integrates oil-conducting cotton, heating wire, and solidified pulp.

[0017] This invention only requires the following steps: manufacturing the heating core → preparing the suspension slurry → metering the suspension slurry → baking and demolding the mold core → sintering and demolding. The above process can produce a heating core that integrates oil-conducting cotton, heating wire, and solidified slurry. The manufacturing process is simple. The heating core produced by this embodiment only needs to be simply assembled with a silicone pad, fiberglass tube, oil-collecting cotton, and PC outer tube before adding e-liquid and sealing it, which greatly reduces the assembly difficulty and improves product stability and production efficiency.
