Description

Technical Field

[0001] This utility model relates to the field of pulp molding production equipment, specifically a drying device for pulp molding production. Background Technology

[0002] Pulp molding is an innovative packaging material production technology that uses waste paper as the main raw material, supplemented with various additives, to produce an advanced packaging liner material. This material excels in protection, shock absorption, compression resistance, and antistatic properties. Its waste components are recyclable and, even if disposed of in landfills, easily decompose into natural fibers, thus becoming an alternative to polystyrene foam. Pulp molding technology not only helps reduce environmental pollution but also supports the concept of sustainable development due to the renewable nature of its raw materials.

[0003] In the production of pulp molded products, the molded products need to be dried. Current technologies mostly employ natural drying or static drying structures. While these methods achieve the desired drying effect, they still present several problems. First, natural drying is inefficient and produces inconsistent results, leading to longer production cycles and impacting overall production efficiency. Second, static drying structures result in a limited drying temperature, making the products prone to warping and deformation. This not only affects the product's appearance but may also reduce its usability. Utility Model Content

[0029] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] like Figures 1-6As shown, in some embodiments, a drying device for pulp molding production includes an upward guiding mechanism 2, a drive mechanism 3, and a supporting mechanism 4. These three components work together to complete the drying process of the pulp molded products. The drive mechanism 3 is embedded inside the upward guiding mechanism 2, while the supporting mechanism 4 is slidably connected to the upward guiding mechanism 2.

[0032] This design allows the supporting mechanism 4 to move flexibly within the upward guide mechanism 2. The main function of the drive mechanism 3 is to drive the supporting mechanism 4 to move effectively, thereby ensuring that the pulp molded products are thoroughly and efficiently dried in the drying equipment. This design of the drying equipment not only significantly improves drying efficiency but also ensures the drying quality of the pulp molded products. In addition, this design makes the drying process more efficient, greatly improving production efficiency.

[0033] The upward guiding mechanism 2 includes an upward guide rail 21 and a transmission rack 23, with the transmission rack 23 precisely positioned at one end of the upward guide rail 21. The carrying mechanism 4 includes a transmission gear 41, a connecting plate 42, a connecting shaft 43, and a carrying plate 44. The transmission gear 41 is precisely positioned on top of the connecting shaft 43, and the other end of the connecting shaft 43 passes through the connecting plate 42. The carrying plate 44 is connected to the connecting shaft 43. As the carrying mechanism 4 moves forward, the meshing connection between the transmission gear 41 and the transmission rack 23 drives the carrying plate 44 to rotate precisely, ensuring uniform heating of all surfaces of the pulp molded product, thereby achieving efficient drying of the pulp molded product.

[0034] This design makes the drying equipment more compact and easier to operate, while also significantly improving drying efficiency. Furthermore, the meshing connection between the transmission gear 41 and the transmission rack 23 ensures the continuity and stability of the drying process, further enhancing drying quality and ensuring optimal drying results for the pulp molded products.

[0035] Through the precise meshing design of the transmission rack 23 of the upward guide mechanism 2 and the transmission gear 41 of the bearing mechanism 4, the automatic rotation function of the bearing mechanism 4 is realized during the conveying process, ensuring that the products on the bearing plate 44 can be heated evenly in all directions, thereby improving the drying quality of pulp molded products.

[0036] In addition, the effective driving of the drive mechanism 3 enables the bearing mechanism 4 to move smoothly, ensuring that the products can be continuously dried, thereby improving the drying efficiency.

[0037] Furthermore, in some embodiments, the drying equipment also includes a drying chamber 1, which is disposed on one side of the upward guide mechanism 2 and is correspondingly disposed with respect to the transmission rack 23.

[0038] The interior of the drying chamber 1 is divided into a preheating zone, a main drying zone, and a balancing zone along the direction of travel of the pulp molded products. Specifically, a preheating plate 6, a main drying plate 7, and a balancing plate 8 are respectively installed in the preheating zone, the main drying zone, and the balancing zone. This design ensures that the pulp molded products are dried evenly during the drying process, thereby guaranteeing the drying quality.

[0039] Specifically, in the preheating zone, the preheating plate 6 uses radiant heating to initially fix the shape of the pulp molded products. In the main drying zone, the main drying plate 7 uses hot air to heat the pulp molded products, causing rapid evaporation of moisture. In the balancing zone, a balancing plate 8 is installed to heat the products at a low temperature, using a slow drying method to eliminate internal stress and improve the drying quality of the products. This design ensures that the pulp molded products receive appropriate treatment at different stages, thereby optimizing the drying effect.

[0040] like Figure 3 and Figure 7 As shown, in some embodiments, the upward guiding mechanism 2 further includes a support frame 22, which is fixedly connected to the upward guide rail 21. The bottom of the support frame 22 is connected to the downward guide rail 5, so that the upward guide rail 21 and the downward guide rail 5 are arranged parallel to each other, forming a closed loop path to ensure the stability of the operation of the carrying mechanism 4. The support frame 22 provides stable support for the carrying mechanism 4, ensuring the smooth operation of the drying process.

[0041] Specifically, the upward guide rail 21 is equipped with a slide rail, and the connecting plate 42 is slidably connected to the slide rail. The connecting shaft 43 passes through the slide rail and is connected to the support plate 44, allowing the support mechanism 4 to move stably and flexibly within the upward guide rail 21. In addition, the downward guide rail 5 is equipped with a groove, and the bottom of the support mechanism 4 moves along the groove, thereby improving drying efficiency.

[0042] like Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, multiple support plates 44 are provided, which are arranged up and down radially along the connecting shaft 43. Products are placed on the support plates 44. With this design, multiple products can be dried at the same time, improving drying efficiency.

[0043] The bottom of the connecting shaft 43 is provided with a guide rod 46, which is slidably connected to the slide groove to ensure that the bearing mechanism 4 can move smoothly during the drying process.

[0044] Specifically, the support plate 44 is equipped with a bushing 45, which is fixedly connected to the connecting shaft 43, ensuring that the support plate 44 can rotate with the connecting shaft 43. The support plate 44 is designed as a perforated plate to facilitate the discharge of moisture. This design allows the pulp molded products to be fully dried during the drying process, while also facilitating the discharge of moisture, thereby improving the drying quality.

[0045] like Figure 8 As shown, in some embodiments, the drive mechanism 3 includes a drive motor 31, a transmission wheel 32 connected to the output shaft of the drive motor 31, a transmission chain 33 meshing with the transmission wheel 32, and a plurality of push plates 34 fixed at intervals on the transmission chain 33. These push plates 34 are designed to push the connecting plate 42 to move, thereby pushing the carrying mechanism 4 to move along the upward guide rail 21. This design allows the drive mechanism 3 to effectively drive the carrying mechanism 4, thus ensuring the drying quality of the pulp molded products. Simultaneously, this design improves drying efficiency. The combination of the drive motor 31 and the transmission chain 33 provides a power source for the drying equipment, ensuring the continuity and stability of the drying process.

[0046] The typical working process of the above embodiments is as follows:

[0047] Step 1:

[0048] The wet blank is placed on the support plate 44, the drive motor 31 is started, the transmission chain 33 moves accordingly, and then pushes the push plate 34 to make the connecting plate 42 move forward along the upward guide rail 21.

[0049] Step 2: After the wet blank enters the preheating zone, the preheating plate 6 performs preliminary preheating and drying on the wet blank on the support plate 44 to achieve preliminary shaping of the wet blank. During the forward movement of the support mechanism 4, the transmission gear 41 meshes with the transmission rack 23, driving the support mechanism 4 to rotate, ensuring that the wet blank on the support plate 44 can be dried.

[0050] Step 3: In the main drying zone, the main drying plate 7 performs deep drying on the shaped wet blanks to promote rapid evaporation of moisture. Similarly, in this zone, the supporting mechanism 4 rotates synchronously as it moves forward to ensure that all products are dried.

[0051] Step 4: In the balancing zone, the drying temperature of the balancing plate 8 is set lower than that of the main drying plate 7 to eliminate internal stress through slow drying and ensure the stability of the product dimensions. In this zone, the supporting mechanism 4 can also rotate.

[0052] Step 5: After the bearing mechanism 4 leaves the balance zone, remove the dried product and continue to put in a new wet preform. Repeat this process to achieve continuous drying of pulp molded products.
