Description

Technical Field

[0001] This invention belongs to the technical field of fully automatic plant fiber molding equipment, specifically relating to a fully automatic plant fiber molding equipment. Background Technology

[0002] Plant fiber molded products are made from fully recyclable plant fiber pulp as the base material. The plant fiber pulp is adsorbed into a special mold using a vacuum to form a wet blank. The finished product is formed through processes such as drying and trimming. They are widely used in food (pharmacy) containers, electrical appliance packaging, planting and seedling cultivation, medical utensils, handicraft blanks and fragile item padding packaging, etc., and are pollution-free, technologically advanced, green and environmentally friendly products.

[0003] In current plant fiber molding processes, the slurry is quickly poured into the mold by submerging it in a slurry tank. The molding process is then achieved through negative pressure extraction. During this extraction, the slurry is discharged through the negative pressure holes in the mold. As a result, the slurry in the mold tends to accumulate at the bottom, leading to a greater thickness at the bottom than at the top of the molded plant fiber. This uneven thickness affects the quality of the molded plant fiber and makes it difficult to meet customers' demands for high-precision plant fiber molding.

[0004] In addition, existing plant fiber molding equipment requires manual intervention during the molding process. The rapid opening and closing of the upper and lower molds during the molding process often results in workers being pinched or injured. This can lead to serious injuries and other problems for workers. Manual intervention also affects the production efficiency of plant fiber molding equipment.

[0005] Chinese patent application CN114717881A discloses a pulp molding production line, including a molding machine, a hot press, and a robot. The robot includes a rotary table with a robotic arm mounted on it. The robotic arm has a rotating device and a transfer mold mounted on the rotating device. The transfer mold has a material handling and transfer surface on one side and a product handling surface on the other side. The material handling and transfer surface is used to transfer the wet blank after molding, and the product handling surface is used to remove the product after hot pressing. The material handling and transfer surface is equipped with a material handling mold with a material handling suction hole. The product handling surface is equipped with a part-removing suction cup. This system can automatically send the wet blank pressed by the molding machine to the hot press and automatically send the product pressed by the hot press away, realizing the automation and intelligence of pulp molding production. It can be flexibly matched with various pulp molding production lines and can be configured with different models and quantities of molding machines and hot presses as needed. This pulp molding production line uses a traditional pulp production process, in which the molding die is sunk into the pulp tank to achieve pulp molding. This not only causes pulp splashing, but also results in uneven thickness of the molded pulp, affecting the quality of the pulp molding. Summary of the Invention

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] (1) By designing a molding device and a drying device inside the molding cylinder, the present invention can realize the integrated molding and drying process of plant limiting molding, thereby realizing the fully automatic molding and drying process of plant fiber molding, effectively improving the preparation accuracy and efficiency of plant fiber molding, reducing the degree of manual intervention in the molding and drying process of plant fiber molding, and thus improving the production efficiency of plant fiber molding; the molding device continuously provides plant fiber slurry to the molding mechanism by setting a slurry chamber inside the molding cylinder, and the slurry mixing mechanism in the slurry chamber prevents the plant fiber slurry in the slurry chamber from settling. The mixing degree of the slurry is maintained by the continuous operation of the slurry mixing mechanism, thereby improving the molding effect of plant fiber molded products.

[0021] (2) The mixing mechanism drives the upper mixing rod and the lower mixing rod to move synchronously, asynchronously or in opposite directions through the upper mixing ring and the lower mixing ring, respectively, to continuously stir the plant fiber slurry in the slurry cavity, effectively preventing the plant fiber slurry from settling, and at the same time keeping the plant fiber slurry in a stable mixing state, which can improve the uniformity of the plant fiber molded products, prevent the plant fiber molding from settling and causing uneven product thickness, and thus ensure the molding quality of plant fiber molding; the lower mixing motor meshes with the lower mixing wheel teeth on the outer periphery of the lower mixing ring, driving the lower mixing ring to move along the mixing roller through the lower annular groove, thus facilitating continuous mixing of the plant fiber slurry in the slurry cavity; the upper mixing ring meshes with the upper mixing wheel teeth of the mixing concave wheel through the mixing toothed rack on one side of the upper annular groove, and the rotation of the mixing concave wheel drives the upper mixing ring to rotate continuously in the slurry cavity, thereby achieving the purpose of continuous mixing of plant fiber slurry.

[0022] (3) The upper mixing motor drives the mixing concave wheel through the mixing shaft to achieve the purpose of driving the upper mixing ring to mix and stir in the slurry cavity; the lower mixing rod and the upper mixing rod rotate synchronously, asynchronously or in opposite directions in the slurry cavity, while the plant fiber slurry impacts the mixing impeller, causing the mixing impeller to rotate along the mixing bearing in the slurry cavity, which can cooperate with the lower mixing rod and the upper mixing rod to continuously mix the plant fiber slurry in the slurry cavity, thereby effectively improving the mixing degree and uniformity of the plant fiber slurry, and effectively preventing the plant fiber slurry from settling and causing a decline in the quality of plant fiber molding; the limiting ring on the outside of the upper mixing ring moves along the limiting ring groove in the slurry cavity with the upper mixing ring to prevent the upper mixing ring from tilting or shifting when rotating in the slurry cavity, affecting the mixing effect of the plant fiber slurry, and also reducing the probability of failure of the mixing mechanism.

[0023] (4) The molding mechanism is connected to the molding support and the liquid collection cylinder in the molding cylinder to facilitate the discharge of waste liquid generated during the molding process, prevent the waste liquid from overflowing and affecting the molding environment of plant fiber molding in the molding cylinder, prevent the waste liquid from affecting the molding quality of plant fiber molding, and facilitate the collection and reuse of waste liquid after molding; the lower molding structure on the molding support is connected to the upper molding structure in the molding cylinder to perform the molding action of plant fiber molding in the molding cylinder; the lower molding structure is connected to the lower molding mold and the negative pressure molding shell to quickly extract the waste liquid generated during the molding process of plant fiber molding, so as to facilitate the efficient production of plant fiber molded products.

[0024] (5) The negative pressure fan draws negative pressure into the negative pressure molding shell during the molding process through the negative pressure pipe, thereby quickly discharging the waste liquid generated during the molding process of the lower molding mold, which facilitates the rapid production of plant fiber molded products; the lower molding mold can be adjusted up and down under the action of the lower molding push rod, which facilitates the molding transfer structure to transfer the molded plant fiber mold to the drying device for drying treatment; the retractable protective sleeve can prevent the waste liquid from affecting the lower molding push rod, thereby causing the lower molding push rod to malfunction; the lower guide strip, together with the negative pressure guide groove, guides the lifting and lowering of the lower molding mold, preventing the lower molding mold from shifting after lifting and lowering, which would cause it to fail to seal with the negative pressure molding shell and affect the negative pressure suction capacity of the negative pressure molding shell for waste liquid.

[0025] (6) The sealing gasket prevents the sealing effect between the lower molding mold and the negative pressure molding shell from failing after the lower molding mold is raised and lowered, and improves the sustainability of the negative pressure when the negative pressure molding shell extracts waste liquid; the negative pressure molding hole facilitates the discharge of waste liquid through the negative pressure molding shell; the lower molding groove not only facilitates the concealment of the negative pressure molding shell and the lower molding mold inside, but also collects the waste liquid splashed by the lower molding mold during the plant fiber molding process, thereby preventing the waste liquid from affecting the plant fiber molded products.

[0026] (7) The molding transfer structure can automatically and accurately transfer the molded plant fiber mold to the drying device for drying, which facilitates the molding of plant fiber mold again, reduces the degree of manual intervention, prevents injury to personnel during the molding process, and achieves the purpose of fully automatic molding and drying of plant fiber mold; the molding transfer structure drives the molding bracket to rotate along the molding bearing on the molding support through the molding motor, so that it can accurately adjust its position according to the different sizes of the lower molding mold and the upper molding mold, which facilitates the accurate negative pressure suction of the molded plant fiber mold and the accurate transfer of plant fiber molds of different sizes; by adsorbing the molded plant fiber mold through the transfer suction cup, the damage to the plant fiber mold during the transfer process can be reduced, thereby ensuring the quality of the plant fiber mold.

[0027] (8) The adjusting motor drives the adjusting shaft to rotate along the adjusting bearing on the forming transfer plate by meshing with the adjusting gear, thereby driving the transfer suction cup to adjust the angle through the transfer linkage. The transfer suction cup rotates along the transfer shaft at the bottom of the transfer linkage under the action of gravity, so that the transfer suction cup is always vertically downward, which makes it convenient for the transfer suction cup to always grasp the plant fiber molding. The displacement motor on the forming bracket can drive the forming transfer plate to move left and right along the forming bracket by meshing with the displacement rack, thereby adjusting the position of the transfer suction cup, which makes it convenient for the transfer suction cup to transfer the plant fiber molding to the drying device.

[0028] (9) The upper molding structure pushes the upper molding mold and the molding concave wheel up and down along the upper molding guide groove in the upper molding guide rod on both sides through the upper molding push rod, and cooperates with the lower molding mold to perform the mold opening and closing action, thereby realizing the molding production of plant fiber molding; the reset spring can cooperate with the upper molding push rod to drive the upper molding mold to quickly reset, thereby facilitating the plant fiber molding operation again; the setting of the slurry injection shell facilitates the uniform injection of the slurry in the slurry cavity into the lower molding mold through the slurry injection shell, and the slurry injection port cooperates with the slurry guide groove to facilitate the efficient and uniform injection of slurry into the lower molding mold, thereby improving the molding accuracy and efficiency of plant fiber molding; the sealing ring prevents the slurry from flowing out when the upper and lower molding molds are closed.

[0029] (10) The drying device drives multiple drying shafts to rotate inside the molding cylinder through a pair of drying tracks, which in turn drives the molding dryers on the drying shafts to move inside the molding cylinder. This allows the molding dryers to combine with the molding transfer structure in sequence, making it convenient to transfer the molded plant fiber mold to the molding dryer. The molding dryer then dries the plant fiber mold. The molding dryer dries the molded plant fiber mold through a drying heating grid and quickly discharges the moisture from the plant fiber mold during drying through the drying holes. The dried plant fiber mold slides out of the molding cylinder through the molding slide on the molding port, achieving the purpose of fully automatic molding and drying of plant fiber mold.

[0030] In summary, this invention installs a molding device and a drying device inside the molding cylinder. By performing integrated plant fiber molding and drying within the molding cylinder, it achieves fully automated molding and drying of plant fiber molding, effectively improving the preparation accuracy and efficiency of plant fiber molding, reducing manual intervention in the molding and drying process, and thus increasing the production efficiency of plant fiber molding. The dried plant fiber mold slides out of the molding cylinder through the molding slide on the molding port, achieving the purpose of fully automated molding and drying of plant fiber molding, thereby effectively improving the quality of plant fiber molding and increasing the degree of automation in plant fiber molding.

[0052] A method for a fully automated plant fiber molding equipment includes the following steps;

[0053] Step 1: Maintain the mixing degree of the slurry;

[0054] During the plant fiber molding process, the mixing mechanism 4 continuously stirs the plant fiber slurry in the slurry chamber 3 to maintain a uniform mixing degree. Specifically, the upper mixing motor 11 of the mixing mechanism 4 drives the mixing concave wheel 412 through the mixing shaft 403. The mixing concave wheel 412 meshes with the mixing rack 411 on one side of the upper annular groove 402 through the upper mixing wheel teeth 413, driving the upper mixing ring 401 to rotate around the slurry chamber 3. The limiting ring 409 moves in the limiting ring groove through the limiting shaft 417 to guide the upper mixing ring 401. The upper mixing ring 401 drives the mixing impeller 410 to move in the slurry chamber 3 through the upper mixing rod 404. At the same time, the lower mixing motor 12 drives the lower mixing ring 401 through the lower mixing wheel teeth 415. 6. The lower annular groove 414 rotates along the mixing cam 416 on the mixing roller 408, and the lower mixing rod 407 moves with the lower mixing ring 406. Through the synchronous, asynchronous or reverse movement of the upper mixing ring 401 and the lower mixing ring 406, the mixing impellers 410 on the upper mixing rod 404 and the lower mixing rod 407 are driven to move respectively, so that the entire mixing mechanism 4 continuously stirs the plant fiber slurry in the slurry chamber 3. The plant fiber slurry impacts the mixing impeller 410, causing the mixing impeller 410 to rotate along the mixing bearing 405 in the slurry chamber 3. It can cooperate with the mixing rod to continuously mix the plant fiber slurry in the slurry chamber 3, thereby effectively improving the mixing degree and uniformity of the plant fiber slurry and effectively preventing the plant fiber slurry from settling and causing a decline in the quality of plant fiber molding.

[0055] Step two, molding of plant fibers;

[0056] During the plant fiber molding process, the upper molding push rod of the upper molding structure 10 extends, pushing the upper molding mold and molding concave wheel to move up and down along the upper molding guide grooves in the upper molding guide rods on both sides, and closing with the lower molding mold 501 of the lower molding structure 5 in the lower molding groove 8. After the upper molding mold and the lower molding mold 501 are closed, the extracted plant fiber slurry flows into the slurry injection shell, and flows into the slurry guide groove on the outer periphery of the lower molding mold 501 through the slurry injection port at the bottom of the slurry injection shell. The sealing ring prevents the slurry from overflowing, and the slurry quickly fills the gap between the upper molding mold and the lower molding mold 501. The negative pressure fan draws negative pressure into the negative pressure pipe, making... The negative pressure molding shell is in a negative pressure state. After the plant fiber slurry flows through the negative pressure molding hole to the negative pressure pipe, it is temporarily stored in the collection cylinder 6 for recycling. The plant fibers in the plant fiber slurry are attached to the gap between the upper molding mold and the lower molding mold 501. As the plant fiber slurry continues to flow in, a plant fiber mold with uniform thickness is obtained under the action of the upper molding mold and the lower molding mold 501. The injection of plant fiber slurry stops, and then the upper molding mold rises under the action of the upper molding push rod and then falls again to close the mold, extruding the negative pressure molded plant fiber. The molding quality and quality of the plant fiber mold are improved through secondary molding.

[0057] After molding is completed, the lower molding push rod, which is fixed in the negative pressure molding shell 502 by the fixing rod, extends and pushes the guide strip of the lower molding mold 501 to move upward along the negative pressure guide groove in the negative pressure molding shell 502. The lower molding mold 501 separates from the negative pressure molding shell 502, which makes it easy to lift the molded plant fiber to a suitable height and facilitate the transfer and drying of the plant fiber mold.

[0058] Step 3, Transfer of plant fiber molding;

[0059] After the plant fiber is molded, the molded plant fiber is transferred to the drying device using the molding transfer structure 2. The specific steps are as follows: after the plant fiber is molded, while the upper molding mold retracts, the molding motor 205 drives the molding bracket 201 to rotate along the molding bearing 206 on the molding support 7 by a specified angle (15, 30, 45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195, 210, 225, 240, 255, 270, 285 degrees), so that the molding transfer plate 202 is directly facing the lower molding mold 501. At this time, the transfer suction cup 204 is directly above the molded plant fiber and is located at the center of gravity of the plant fiber. Under the action of negative pressure, the transfer suction cup 204 sucks the plant fiber mold away from the lower molding mold 501.

[0060] Then, the displacement motor 207 starts, and the displacement gear 208 at the movable end of the displacement motor 207 meshes with the displacement rack 203, driving the molding transfer plate 202 to move along the transfer sleeve 209 in the transfer adjustment hole 210 on the molding bracket 201 towards the drying track side, driving the plant fiber mold on the transfer suction cup 204 to approach the drying shell. The adjustment motor starts, and the movable end of the adjustment motor meshes with the adjustment gear 214, driving the adjustment shaft 213 to rotate along the adjustment bearing 212 on the molding transfer plate 202, so that the plant fiber mold on the transfer suction cup 204 corresponds to the drying shell. Under the action of gravity, the transfer suction cup 204 rotates along the transfer shaft 215 at the end of the transfer connecting rod 211, so that the transfer suction cup 204 is always in a vertical state, which makes it convenient to place the plant fiber mold on the transfer suction cup 204 onto the drying shell for drying treatment.

[0061] Step four: Drying and collecting the plant fiber moldings;

[0062] After the molding transfer structure 2 transfers the molded plant fiber mold to the drying shell of the molding dryer, the molded plant fiber mold gradually dries under the action of the drying heating mesh. The water vapor generated during drying is discharged along the drying hole and then discharged through the exhaust hole set on the molding cylinder 1. During the drying process of the plant fiber mold, the drying shaft moves along the rotating drying track to the molding port, and then detaches from the drying shell under the action of gravity and slides along the molding slide 9 into the collection box, which facilitates the reprocessing of the dried plant fiber mold.

[0063] Example 2

[0064] A method for a fully automated plant fiber molding equipment includes the following steps;

[0065] Step 1: Maintain the mixing degree of the slurry;

[0066] During the plant fiber molding process, the mixing mechanism 4 continuously stirs the plant fiber slurry in the slurry chamber 3 to maintain a uniform mixing degree. Specifically, the upper mixing motor 11 of the mixing mechanism 4 drives the mixing concave wheel 412 through the mixing shaft 403. The mixing concave wheel 412 meshes with the mixing rack 411 on one side of the upper annular groove 402 through the upper mixing wheel teeth 413, driving the upper mixing ring 401 to rotate around the slurry chamber 3. The limiting ring 409 moves in the limiting ring groove through the limiting shaft 417 to guide the upper mixing ring 401. The upper mixing ring 401 drives the mixing impeller 410 to move in the slurry chamber 3 through the upper mixing rod 404. At the same time, the lower mixing motor 12 drives the lower mixing ring 401 through the lower mixing wheel teeth 415. 6. The lower annular groove 414 rotates along the mixing cam 416 on the mixing roller 408, and the lower mixing rod 407 moves with the lower mixing ring 406. Through the synchronous, asynchronous or reverse movement of the upper mixing ring 401 and the lower mixing ring 406, the mixing impellers 410 on the upper mixing rod 404 and the lower mixing rod 407 are driven to move respectively, so that the entire mixing mechanism 4 continuously stirs the plant fiber slurry in the slurry chamber 3. The plant fiber slurry impacts the mixing impeller 410, causing the mixing impeller 410 to rotate along the mixing bearing 405 in the slurry chamber 3. It can cooperate with the mixing rod to continuously mix the plant fiber slurry in the slurry chamber 3, thereby effectively improving the mixing degree and uniformity of the plant fiber slurry and effectively preventing the plant fiber slurry from settling and causing a decline in the quality of plant fiber molding.

[0067] Step two, molding of plant fibers;

[0068] During the plant fiber molding process, the upper molding push rod of the upper molding structure 10 extends, pushing the upper molding mold and molding concave wheel to move up and down along the upper molding guide grooves in the upper molding guide rods on both sides, and closing with the lower molding mold 501 of the lower molding structure 5 in the lower molding groove 8. After the upper molding mold and the lower molding mold 501 are closed, the extracted plant fiber slurry flows into the slurry injection shell, and flows into the slurry guide groove on the outer periphery of the lower molding mold 501 through the slurry injection port at the bottom of the slurry injection shell. The sealing ring prevents the slurry from overflowing, and the slurry quickly fills the gap between the upper molding mold and the lower molding mold 501. The negative pressure fan draws negative pressure into the negative pressure pipe, making... The negative pressure molding shell is in a negative pressure state. After the plant fiber slurry flows through the negative pressure molding hole to the negative pressure pipe, it is temporarily stored in the collection cylinder 6 for recycling. The plant fibers in the plant fiber slurry are attached to the gap between the upper molding mold and the lower molding mold 501. As the plant fiber slurry continues to flow in, a plant fiber mold with uniform thickness is obtained under the action of the upper molding mold and the lower molding mold 501. The injection of plant fiber slurry stops, and then the upper molding mold rises under the action of the upper molding push rod and then falls again to close the mold, extruding the negative pressure molded plant fiber. The molding quality and quality of the plant fiber mold are improved through secondary molding.

[0069] After molding is completed, the lower molding push rod, which is fixed in the negative pressure molding shell 502 by the fixing rod, extends and pushes the guide strip of the lower molding mold 501 to move upward along the negative pressure guide groove in the negative pressure molding shell 502. The lower molding mold 501 separates from the negative pressure molding shell 502, which makes it easy to lift the molded plant fiber to a suitable height and facilitate the transfer and drying of the plant fiber mold.

[0070] Step 3, Transfer of plant fiber molding;

[0071] After the plant fiber is molded, the molded plant fiber is transferred to the drying device using the molding transfer structure 2. The specific steps are as follows: after the plant fiber is molded, while the upper molding mold retracts, the molding motor 205 drives the molding bracket 201 to rotate along the molding bearing 206 on the molding support 7 by a specified angle (15, 30, 45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195, 210, 225, 240, 255, 270, 285 degrees), so that the molding transfer plate 202 is directly facing the lower molding mold 501. At this time, the transfer suction cup 204 is directly above the molded plant fiber and is located at the center of gravity of the plant fiber. Under the action of negative pressure, the transfer suction cup 204 sucks the plant fiber mold away from the lower molding mold 501.

[0072] Then, the displacement motor 207 starts, and the displacement gear 208 at the movable end of the displacement motor 207 meshes with the displacement rack 203, driving the molding transfer plate 202 to move along the transfer sleeve 209 in the transfer adjustment hole 210 on the molding bracket 201 towards the drying track side, driving the plant fiber mold on the transfer suction cup 204 to approach the drying shell. The adjustment motor starts, and the movable end of the adjustment motor meshes with the adjustment gear 214, driving the adjustment shaft 213 to rotate along the adjustment bearing 212 on the molding transfer plate 202, so that the plant fiber mold on the transfer suction cup 204 corresponds to the drying shell. Under the action of gravity, the transfer suction cup 204 rotates along the transfer shaft 215 at the end of the transfer connecting rod 211, so that the transfer suction cup 204 is always in a vertical state, which makes it convenient to place the plant fiber mold on the transfer suction cup 204 onto the drying shell for drying treatment.

[0073] Step four: Drying and collecting the plant fiber moldings;

[0074] After the molding transfer structure 2 transfers the molded plant fiber mold to the drying shell of the molding dryer, the molded plant fiber mold gradually dries under the action of the drying heating mesh. The water vapor generated during drying is discharged along the drying hole and then discharged through the exhaust hole set on the molding cylinder 1. During the drying process of the plant fiber mold, the drying shaft moves along the rotating drying track to the molding port, and then detaches from the drying shell under the action of gravity and slides along the molding slide 9 into the collection box, which facilitates the reprocessing of the dried plant fiber mold.
