Description

Technical Field

[0001] The invention relates to the technical field of betel nut molding production, in particular to a method for making betel nut pressed molding. Background Art

[0002] Betel nut is the mature fruit of the Areca palm, a plant of the palm family. It is slightly smaller than an egg, with a fibrous peel and a seed, the betel nut. The main active ingredient of betel nut is arecoline.

[0003] At present, during the production of betel nuts, betel nuts are generally pressed, usually by introducing a whole barrel of betel nuts into a pressing and molding device, and then pressing each betel nut into a certain shape by pressing the upper mold and the lower mold in the pressing and molding device together, thereby realizing the molding production of betel nuts. However, in the above-mentioned betel nut molding method, due to the phenomenon of betel nuts stacking or uneven distribution when pouring, the pressing device cannot perform personalized pressing on each betel nut, resulting in inconsistent styles of each betel nut, affecting the aesthetics of the betel nut and reducing the overall quality of the betel nut.

[0004] Therefore, a method for preparing betel nut by pressing and molding is urgently needed to solve the above problems. Summary of the invention

[0005] Based on the above, the purpose of the present invention is to provide a method for producing betel nut pressed into shape, so as to solve the problem of betel nut stacking or uneven distribution in the existing betel nut molding method, resulting in inconsistent styles of each betel nut.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A method for preparing betel nut pressed molding comprises the following steps:

[0008] S1, the lower mold flows back into the first lifting mechanism, and the image of the lower mold is captured by the visual component to check whether there is betel nut or foreign matter remaining in the lower mold;

[0009] S2, the lower mold is loaded with betel nuts under the operation of the loading mechanism, and the betel nuts are evenly distributed in the lower mold through the coordinated action of the first rotating table and the shaking component of the loading assembly; then the betel nuts are transferred to the manual feeding table, and the positions on the lower mold where no material is loaded or multiple materials are loaded are manually fed or unloaded; at the same time, the lower mold is also abnormally processed according to the results after image capture;

[0010] S3: the lower molds after loading are arranged in sequence and enter the baking oven, so that the temperature of the betel nuts in the lower molds reaches the required temperature when the lower molds leave the baking oven;

[0011] S4: The lower mold is sent to the pressing station in the pressing and forming mechanism, and the hydraulic module drives the upper mold on the pressing plate to move downward and close with the lower mold. At the same time, the betel nut is cooled and pressurized to achieve the pressing and forming of the betel nut;

[0012] S5, the lower mold after molding enters the second lifting mechanism, and the height position of the lower mold is adjusted; then the lower mold is sent to the unloading mechanism, and the lower mold is turned 140 degrees by the rotating component, so that all the molded betel nuts are separated from the lower mold and fall into the collecting hopper at the bottom of the automatic unloading mechanism;

[0013] S6: After the material is unloaded, the lower mold is lowered to the reflux mechanism via the third lifting mechanism, and returns to the first lifting mechanism under the action of the reflux mechanism, and the above steps are repeated to enter the next cycle.

[0014] As a preferred solution for the method of making betel nut pressed and molded, in step S1, the internal condition of the lower mold is analyzed based on the information captured by the image. If there are betel nut or foreign matter remaining in the lower mold, the corresponding cavity in the lower mold is marked to facilitate subsequent processing by the staff; if the interior of the lower mold is damaged, the lower mold is directly transferred to the third lifting mechanism along the subsequent path, and then transferred to the outside of the production line for collection.

[0015] As a preferred solution for the production method of betel nut pressing and molding, the visual component also scans the QR code on each lower mold and collects data on it, so that the staff can timely understand the usage and production status of the lower mold.

[0016] As a preferred solution of the method for making betel nut pressed and molded, in step S2, the betel nut is transported to the first rotating table in the feeding assembly through the lifting assembly in the feeding mechanism, and the betel nut is evenly distributed on the first rotating table of the feeding assembly through the action of the rotating part and the shaking part in the feeding assembly.

[0017] As a preferred solution for the method of making betel nut pressed and molded, the first rotating table first rotates clockwise and is fixed by a positioning assembly, and then is shaken by a shaking component. After the shaking, the positioning assembly is released, and then the first rotating table rotates counterclockwise again and is fixed by the positioning assembly on the other side, and is shaken again by a shaking component, so that the betel nut can be evenly distributed in each cavity of the lower mold.

[0018] As a preferred solution for the production method of betel nut pressing and molding, the lower mold after loading flows onto the manual feeding table, and the staff observes whether there are cavities without material or cavities with overlapping betel nuts in the lower mold; if so, betel nuts are loaded into the cavities or excess betel nuts are removed. After the operation is completed, the start button is pressed, and the lower mold automatically flows into the next station; if not, the staff directly presses the start button, and the lower mold automatically flows into the next station.

[0019] As a preferred solution for the method of making betel nut pressed and molded, in step S3, the entire baking oven can accommodate six lower molds at the same time. The lower molds enter the baking oven and are transferred according to a set specific speed so that the lower molds stay in the baking oven for about four minutes. When the lower molds leave the baking oven, the temperature of the betel nut can reach the required temperature.

[0020] As a preferred solution of the method for making betel nut pressed and molded, in step S4, the baked lower mold and the pulling component of the pressing and molding mechanism are engaged with each other, and then the pulling component pulls the baked lower mold into the pressing and molding mechanism, and pushes out the pressed and molded lower mold, thereby realizing the transmission of the lower mold.

[0021] As a preferred solution for the production method of betel nut pressing and molding, when the upper mold and the lower mold are pressed together, the pressure plate is driven downward by the hydraulic module, that is, the upper mold is driven close to the lower mold, and the two are closed, and the pressure needs to be maintained for 30 seconds during pressing.

[0022] As a preferred solution of the method for pressing and molding betel nut, in step S5, when the lower mold moves to the rotating component, the lower mold is limited and fixed by the limiting component and the fixing component on the rotating component to avoid misalignment of the lower mold on the rotating component, so as to ensure that the pushing component on the subsequent rotating component can smoothly feed the molded betel nut into the collecting hopper.

[0023] The beneficial effects of the present invention are:

[0024] By setting up a visual component, a feeding mechanism and a pressing and forming mechanism, the betel nut is transferred to the feeding component in the feeding mechanism through the lifting component in the feeding mechanism, and the coordinated operation of the first rotating table and the shaking component ensures that the betel nut can be evenly distributed in the lower mold to avoid the stacking of betel nut. The visual component is also used to capture the image of the lower mold of the empty tray, which is convenient for subsequent staff to deal with abnormal cavities in the lower mold on the manual feeding table. At the same time, the staff can intuitively observe the distribution of betel nut in the lower mold, feed the cavities or remove excess betel nut, further ensuring that the betel nut is evenly distributed in the lower mold, improving the consistency of the betel nut molding style, and then improving the production quality of betel nut. Through the coordinated operation of the reflux mechanism, the first lifting mechanism, the second lifting mechanism and the third lifting mechanism, the entire process of betel nut molding is automated, which improves the stability of the betel nut production process and the molding quality of betel nut.

[0051] like Figure 1-4 As shown, a method for making betel nut pressed into shape is provided, which is performed by the betel nut forming production line, comprising the following steps:

[0052] S1. The lower mold flows back into the first lifting mechanism 10, and the image of the lower mold is captured by the visual component 50 to check whether there are betel nut or foreign matter remaining in the lower mold. According to the detection results, the lower mold is processed according to the corresponding problems in the subsequent production links to improve the molding quality of the betel nut and ensure the consistency of the betel nut molding.

[0053] Among them, the internal situation of the lower mold is analyzed according to the information captured by the image. If there are betel nuts or foreign objects left in the lower mold, the corresponding cavity in the lower mold is marked to facilitate subsequent processing by the staff. If the interior of the lower mold is damaged, the lower mold is directly transmitted to the third lifting mechanism 14 along the subsequent path, and then transmitted to the outside of the production line for collection, thereby reducing the defective rate of betel nut molding. By processing in different ways according to the information captured by different images, the production efficiency of betel nut pressing and molding is improved, and the molding quality of betel nut is also improved.

[0054] Furthermore, the visual component 50 also scans the QR code on each lower mold and collects data thereof, so that the staff can timely understand the usage and production status of the lower mold. At the same time, it can also perform usage analysis based on the usage and production status of the lower mold to determine whether the lower mold should continue to be used or be repaired and maintained, thereby increasing the service life of the lower mold.

[0055] S2, the lower mold is loaded with betel nuts under the operation of the loading mechanism, and the betel nuts are evenly distributed in the lower mold through the coordinated action of the first rotating table 212 and the shaking component 213 of the loading assembly 21. Then it is transferred to the manual feeding station 11, and the positions on the lower mold where no material is loaded or multiple materials are loaded are manually fed or unloaded. At the same time, the lower mold is also abnormally processed according to the results of image capture.

[0056] The betel nuts are transported to the first rotating table 212 in the feeding assembly 21 through the lifting assembly 20 in the feeding mechanism, and the betel nuts are evenly distributed on the first rotating table 212 of the feeding assembly 21 through the action of the rotating component and the shaking component 213 in the feeding assembly 21. The lower mold on the first rotating table 212 is shaken in the corresponding inclined directions on both sides of the lower mold through the coordinated action of the rotating component and the shaking component 213, so that the betel nuts can be evenly distributed in each cavity of the lower mold, avoiding the phenomenon of multiple betel nuts stacking in a single cavity.

[0057] Furthermore, the first rotating table 212 rotates clockwise first and is fixed by the positioning assembly 23, and then is shaken by the shaking component 213. After the shaking, the positioning assembly 23 is released, and then the first rotating table 212 rotates counterclockwise again and is fixed by the positioning assembly 23 on the other side, and is shaken again by the shaking component 213, so that the betel nut can be evenly distributed in each cavity of the lower mold. Among them, the clockwise and counterclockwise rotation angles can be 30-45°, and the specific angles can be selected according to actual production conditions. The first rotating table 212 is locked in the corresponding steps through the positioning components 23 on both sides. Such a design makes the first rotating table 212 and the loading workbench 211 in the loading component 21 tightly combined to form a whole. When shaking, part of the shaking force is effectively dispersed and transmitted to the loading workbench 211, avoiding most of the shaking force from being concentrated on the connecting parts between the first rotating table 212 and the loading workbench 211, reducing the load pressure of the connecting parts, and extending the service life of the first rotating table 212.

[0058] Further, the lower mold after loading flows into the artificial feeding table 11, and the staff observes whether there are cavities without loading or cavities with overlapping betel nuts in the lower mold. If yes, betel nuts are loaded into the empty cavities or excess betel nuts are removed. After the operation is completed, the start button is pressed, and the lower mold automatically flows into the next station. If not, the staff directly presses the start button, and the lower mold automatically flows into the next station. The staff observes the lower mold after feeding, and further ensures that each cavity in the lower mold has a betel nut, avoiding the situation of empty cavities or multiple materials in one cavity, and improving the molding quality of betel nuts.

[0059] S3: The lower molds after loading are arranged in sequence and enter the baking oven 12, so that the temperature of the betel nut in the lower mold can reach the required temperature when the lower mold leaves the baking oven 12. Among them, the entire baking oven 12 can accommodate six lower molds at the same time. The lower molds enter the baking oven 12 and are transferred according to the set specific speed, so that the lower molds stay in the baking oven 12 for about four minutes. When the lower molds leave the baking oven 12, the temperature of the betel nut reaches the required temperature, preferably 80-100°C. By setting the baking oven 12, the temperature of the betel nut can reach the required temperature when the lower mold leaves, which is conducive to the pressing and forming of the betel nut, and also ensures the quality and taste of the betel nut after forming.

[0060] In other embodiments, the length of the baking oven 12 can be selected according to actual production conditions, and the length of time each lower mold stays in the baking oven 12 is also determined according to actual production conditions, as long as the actual production conditions can be met.

[0061] S4: The lower mold is sent to the pressing station in the pressing and molding mechanism 30, and the hydraulic module 32 drives the upper mold on the pressing plate to move downward and close with the lower mold. At the same time, the betel nut is cooled and pressurized to achieve the pressing and molding of the betel nut.

[0062] The baked lower mold is engaged with the material pulling component 35 of the pressing and forming mechanism 30, and then the material pulling component 35 pulls the baked lower mold into the pressing and forming mechanism 30, and pushes out the pressed and formed lower mold, thereby realizing the transmission of the lower mold. The front and rear lower molds are transported by the material pulling component 35, so that the rear group of lower molds can be accurately moved to the pressing station of the pressing and forming mechanism 30, ensuring the pressing accuracy between the lower mold and the upper mold, and improving the molding effect of betel nut. At the same time, when the rear group of lower molds is transmitted, the front group of lower molds is pushed out and sent to the transmission mechanism of the next process, thereby realizing the feeding and discharging of the front and rear lower molds, simplifying the transmission steps of the two, and improving the production efficiency of betel nut.

[0063] Furthermore, when the upper mold and the lower mold are pressed together, the hydraulic module 32 drives the pressing plate to move downward, that is, drives the upper mold close to the lower mold, and the two molds are closed, and the pressure needs to be maintained for 30 seconds during the pressing. By pressing the upper mold and the lower mold together and maintaining the pressure for a certain period of time, it is ensured that each betel nut can be fully pressed together, the molding rate of the betel nut is improved, and the style of each betel nut is more consistent, which improves the beauty and overall quality of the betel nut.

[0064] In other embodiments, the holding time between the upper mold and the lower mold can be selected according to actual production conditions, as long as it can meet actual production requirements.

[0065] S5, the lower mold after molding enters the second lifting mechanism 13, and the height position of the lower mold is adjusted. By adjusting the height of the lower mold by the second lifting mechanism 13, the height of the lower mold corresponds to the height of the transmission mechanism of the unloading mechanism 40, so that the lower mold can smoothly enter the unloading mechanism 40, thereby improving the production efficiency of betel nut.

[0066] Then the lower mold is sent to the feeding mechanism 40, and the lower mold is turned 140 degrees by the rotating assembly 41, so that all the formed betel nuts are separated from the lower mold and fall into the collecting hopper 47 at the bottom of the feeding mechanism 40. After the lower mold is turned over, the betel nuts in the cavity of the lower mold are pushed out by the pushing component 42 in the rotating assembly 41, so as to avoid individual betel nuts remaining in the lower mold and affecting the subsequent forming of the lower mold, thereby improving the production quality of betel nuts.

[0067] Furthermore, when the lower mold moves to the rotating assembly 41, the lower mold is limited and fixed by the limiting assembly 44 and the fixing assembly 45 on the rotating assembly 41 to prevent the lower mold from being misaligned on the rotating assembly 41, so as to ensure that the pushing component 42 on the subsequent rotating assembly 41 can smoothly feed the formed betel nut into the collecting hopper 47. By setting the limiting assembly 44, the lower mold can be accurately fixed on the feeding station, so that the push rod 423 on the pushing mechanism can smoothly enter the lower mold, and the push rod 423 is prevented from being misaligned with the lower mold, thereby preventing the push rod 423 from breaking, thereby improving the service life of the pushing mechanism.

[0068] S6: After the material is unloaded, the lower mold is lowered to the reflux mechanism 15 via the third lifting mechanism 14, and returns to the first lifting mechanism 10 under the action of the reflux mechanism 15, and the above steps are repeated to enter the next cycle.

[0069] By setting up the visual component 50, the feeding mechanism and the pressing and forming mechanism 30, the betel nut is transferred to the feeding component 21 in the feeding mechanism through the lifting component 20 in the feeding mechanism, and the first rotating table 212 and the shaking component 213 cooperate to ensure that the betel nut can be evenly distributed in the lower mold to avoid the stacking of the betel nut. The visual component 50 is also used to capture the image of the lower mold of the empty tray, so that the subsequent staff can handle the abnormal cavities of the lower mold on the manual feeding table 11. At the same time, the staff can intuitively observe the distribution of the betel nut in the lower mold, feed the cavities or remove the excess betel nut, further ensuring that the betel nut is evenly distributed in the lower mold, improving the consistency of the betel nut molding style, and then improving the production quality of the betel nut. Through the cooperative operation of the reflux mechanism 15, the first lifting mechanism 10, the second lifting mechanism 13 and the third lifting mechanism 14, the entire process of betel nut molding is automated, which improves the stability of the betel nut production process and the molding quality of the betel nut.

[0070] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention is disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with the profession can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent changes and modifications made to the above embodiments according to the technology of the present invention are within the scope of the technical solution of the present invention without departing from the content of the technical solution of the present invention.

If not, the staff directly presses the start button and the lower mold automatically flows into the next station.

7. The method for making betel nut pressed molding according to claim 1, characterized in that: In step S3, the entire baking oven can accommodate six lower molds at the same time. The lower molds enter the baking oven and are transferred according to the set specific speed, so that the lower molds stay in the baking oven for about four minutes. When the lower molds leave the baking oven, the temperature of the betel nut can reach the required temperature.

8. The method for making betel nut pressed molding according to claim 1, characterized in that: In step S4, the baked lower mold and the pulling component of the pressing and molding mechanism are mutually engaged, and then the pulling component pulls the baked lower mold into the pressing and molding mechanism and pushes the pressed and molded lower mold out, thereby realizing the transmission of the lower mold.

9. The method for making betel nut pressed molding according to claim 8, characterized in that: When the upper mold and the lower mold are pressed together, the hydraulic module drives the pressure plate to move downward, that is, drives the upper mold close to the lower mold and makes the two molds close together, and the pressure needs to be maintained for 30 seconds during pressing.

10. The method for making betel nut pressed molding according to claim 1, characterized in that: In step S5, when the lower mold moves to the rotating assembly, the lower mold is limited and fixed by the limiting assembly and the fixing assembly on the rotating assembly to prevent the lower mold from being misaligned on the rotating assembly, thereby ensuring that the pushing component on the subsequent rotating assembly can smoothly feed the formed betel nut into the collecting hopper.
