Description

Technical Field

[0001] The present invention relates to the technical field of tea processing, and particularly to an intelligent control method and system for a tea pressing machine. Background Art

[0002] During the processing of some existing teas, tea cakes can be made based on a pressing machine.

[0003] However, the structures of existing tea cakes are single and highly homogenized. Most are disc-shaped and can only distinguish between the front and back. Even different manufacturers' information can only be distinguished through the printed content on the tea cake packaging bag (or wrapping paper).

[0004] During the circulation process, the cake tea can be used as a gift. Imprinting words with good meanings (such as: fortune, emolument, longevity, beauty, etc.) and / or patterns on the tea cake can greatly promote the commercial success of the product. Some existing tea carvings are usually used to display the healthy and beautiful images of animals such as flowers, birds, insects, and fish. Most are works of art. In order to extend the display time as much as possible, they are very compact and not easy to eat. And due to high prices and other reasons, they are usually processed and sold individually on the production line with a single tea carving mold. Therefore, how to quickly process and prepare a series of edible tea cakes with different contents has become a technical problem to be solved. Summary of the Invention

[0005] The purpose of the present invention is to disclose an intelligent control method and system for a tea pressing machine to improve the preparation efficiency of a series of edible tea cakes with different contents.

[0006] To achieve the above object, the first method of the present invention includes:

[0007] Step S11: Enter the identity codes and volume calibration amounts respectively corresponding to each tea carving mold on the first driving mechanism, and establish a mapping relationship between any identity code and the corresponding volume calibration amount; at least two series of tea carving molds with different contents and volume calibration amounts are arranged at intervals on the first driving mechanism; the content of each tea carving mold consists of a shape, a pattern, and / or words;

[0008] Step S12: After any tea carving mold is aligned with the pressing cavity, identify the identity code of the tea carving mold currently corresponding to the pressing cavity according to the stroke information of the first driving mechanism, and calculate the target height required for the extrusion force application surface to slide up and down in the pressing cavity to achieve the same density of the series of tea cakes according to the target weight of the currently pressed tea cake and the volume calibration amount corresponding to this identity code. The extrusion force application surface is driven by a second driving mechanism;

[0009] Step S13: After determining that the tea leaves weighed according to the target weight and then steam-treated are loaded into the cake pressing cavity, instruct the second driving mechanism to drive the extrusion force application surface to slide downward to the target height and start timing;

[0010] Step S14: After the pressing time reaches the set extrusion duration, instruct the second driving mechanism to drive the extrusion force application surface to slide upward to the default position, and then after demolding, instruct the first driving mechanism to act so that the next tea carving mold is aligned with the cake pressing cavity and feed the cake pressing cavity, and return to Step S12 to start the next cycle until the target task is completed.

[0011] Preferably, the first driving mechanism is provided with a turntable; the distances between the center points of each tea carving mold and the rotation center of the turntable are the same. Or, the first driving mechanism is a belt that can rotate in a cycle.

[0012] To achieve the above object, the present invention also discloses a second intelligent control method for a tea cake press, including:

[0013] Step S21: Enter the volume calibration amounts respectively corresponding to each tea carving mold on the turntable; at least two series of tea carving molds with different contents and volume calibration amounts are arranged at intervals on the turntable; the content of each tea carving mold consists of shapes, patterns, and / or characters; and there is an adjacent backup for the tea carving molds with the same content so that the arrangement of two different tea carving molds A and B is AABB; the turntable is driven to rotate forward and backward by a third driving mechanism;

[0014] Step S22: Establish a mapping relationship between each cake pressing cavity and the tea carving mold so that during the switching of the forward and reverse rotations of the third driving mechanism for any cake pressing cavity, it is synchronously switched to be aligned with the tea carving molds with the same content that are the main and backup of each other; and calculate the target height required for the extrusion force application surface that slides up and down in the cake pressing cavity to achieve the same density for a series of tea cakes according to the target weight of the currently pressed tea cake and the volume calibration amounts corresponding to each tea carving mold, and the extrusion force application surface is driven by the fourth driving mechanism;

[0015] Among them, each cake pressing cavity is fixed on the workbench, and the number of supporting groups composed of the cake pressing cavity and the fourth driving mechanism arranged on the third driving mechanism is an odd number group arranged at intervals with the tea carving molds;

[0016] Step S23: After determining that the tea leaves weighed according to the target weight and then steam-treated are loaded into each cake pressing cavity, instruct each fourth driving mechanism to drive the extrusion force application surface to slide downward to the corresponding target height and start timing;

[0017] Step S24: After the pressing time reaches the set extrusion duration, instruct the fourth driving mechanism to drive the extrusion force application surface to slide upward to the default position. Then, after demolding, instruct the third driving mechanism to act so that the backup tea carving mold is aligned with the pressing cavity and feed the pressing cavity, and return to step S22 to start the next cycle until the target task is completed.

[0018] Preferably, in the second method, air ducts driven by the same fan are deployed between adjacent supporting groups composed of the pressing cavity and the fourth driving mechanism. Each air duct is only opened during the extrusion duration corresponding to the pressing time, so that among the tea carving molds with the same content that are mutually the main and backup ones, when one is shaping the tea cake, the other is synchronously cleaning the tea cake after demolding.

[0019] Preferably, in the second method, the third driving mechanism is further provided with a transmission mechanism for lifting and lowering the turntable to meet the requirements of closing the lower opening of the pressing cavity after lifting and being able to carry the tea cake without obstruction between the pressing cavity during rotation after lowering.

[0020] Furthermore, in the second method, each tea carving mold is provided with a circular table side surface for alignment with the pressing cavity, and the turntable is provided with at least one drainage port or drainage groove lower than the bottom surface of each circular table.

[0021] To achieve the above object, the present invention also discloses an intelligent control system for a tea cake press, including a memory, a processor, and a computer program stored on the memory and executable on the processor. When the processor executes the computer program, the above first or second method is implemented.

[0022] The present invention has the following beneficial effects:

[0023] 1. The first method is suitable for making one tea cake at a time and making a series with the same density in a time-division multiplexing manner. The second method, on the other hand, works with multiple tea carving molds simultaneously and can synchronously make a series with the same density. Both can be matched with the subsequent production process for storage and packaging according to the series.

[0024] 2. In the present invention, the fluffiness of the tea cake (or can be called "compactness", which is associated with the taste and also with the user experience) is innovatively quantified as density. In the calculation process, the relationship among mass, density, and volume follows the existing common sense, so that the data processing is simple and reliable. Furthermore, when the present invention faces different customer requirements, it can match the different density requirements of downstream customers at low cost and conveniently, and has good compatibility and scalability.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings. Description of the Drawings

The schematic embodiments of the present invention and their descriptions are used to explain the present invention and do not constitute an improper limitation of the present invention. In the drawings:

[0027] Figure 1 It is a schematic flow chart of the intelligent control method of the tea cake press disclosed in Embodiment 1 of the present invention.

[0028] Figure 2 It is a schematic flow chart of the intelligent control method of the tea cake press disclosed in Embodiment 2 of the present invention. Detailed implementation manners

[0029] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways defined and covered by the claims.

[0030] Embodiment 1

[0031] This embodiment discloses an intelligent control method for a tea cake press, as Figure 1 shown, including:

[0032] Step S11: Enter the identity codes and volume calibration amounts respectively corresponding to each tea carving mold on the first driving mechanism, and establish a mapping relationship between any identity code and the corresponding volume calibration amount; at least two series of tea carving molds with different contents and volume calibration amounts are arranged at intervals on the first driving mechanism; the content of each tea carving mold consists of shape, pattern, and / or text.

[0033] In this step, optionally, the first driving mechanism is provided with a turntable or is a belt that can rotate in a cycle. Optionally, the method for calibrating the volume of the tea carving mold can be to put it into a measuring cup filled with water, and the volume after submerging the entire tea carving mold minus the volume without the tea carving mold is the volume calibration amount of the corresponding tea carving mold.

[0034] Step S12: After any tea carving mold is aligned with the cake pressing cavity, identify the identity code of the tea carving mold currently corresponding to the cake pressing cavity according to the stroke information of the first driving mechanism, and calculate the target height required for the extrusion force application surface that needs to slide up and down in the cake pressing cavity to achieve the same density of a series of tea cakes according to the target weight of the currently pressed tea cake and the volume calibration amount corresponding to this identity code. The extrusion force application surface is driven by the second driving mechanism.

[0035] In this step, if the first driving mechanism uses a turntable, preferably, the distances between the center points of each tea carving mold and the rotation center of the turntable are the same, which is convenient for the first driving mechanism to align and rotate with the cake pressing cavity step by step. In this embodiment, the cake pressing cavity can adopt a cylindrical structure with the same horizontal cross-sectional size of the upper and lower through holes, and after alignment, the central axis of the cake pressing cavity is usually on the same straight line as the center of the extrusion force application surface and the center of the tea carving mold. Thereby, during the up and down sliding process of the extrusion force application surface, the volume of the space to be extruded changes linearly. Obviously, the cooperation between the extrusion force application surface and the cake pressing cavity needs to satisfy that the sliding displacement between the two minimizes the control friction while avoiding the overflow of tea leaves.

[0036] In this step, all the parameters used to calculate the target height are known quantities, and the calculation principle is the same as the relationship between weight, volume, and density in the existing same medium, where weight is equal to density multiplied by volume. In this embodiment, the target volume of the tea cake is the remaining volume after subtracting the volume calibration of the corresponding tea carving mold from the inner cavity volume between the bottom of the cake pressing cavity and the target height of the extrusion force application surface, which will not be elaborated later. After the system is powered on, the first alignment of the corresponding tea carving mold on the first driving mechanism and the cake pressing cavity can be flexibly configured by manual participation or automatically aligned based on the relevant parameters calibrated by the system, which is well-known technology to those skilled in the art and will not be elaborated.

[0037] Step S13: After it is judged that the tea leaves weighed by the target weight and then steam-treated are loaded in the cake pressing cavity, the second driving mechanism is instructed to drive the extrusion force application surface to slide down to the target height and then start timing.

[0038] It should be noted that: In this embodiment, the bottom surface of the tea carving mold and the bottom surface of the cake pressing cavity form a sealed common horizontal plane during the cake pressing process.

[0039] Step S14: After the cake pressing time reaches the set extrusion duration, the second driving mechanism is instructed to drive the extrusion force application surface to slide up to the default position, and then after demolding, the first driving mechanism is instructed to act so that the next tea carving mold is aligned with the cake pressing cavity and feeds materials into the cake pressing cavity, and return to step S12 to start the next cycle until the target task is completed.

[0040] In this step, for the convenience of demolding, if the method of matching the cake pressing cavity fixed on the workbench with the turntable is adopted, the turntable should also be capable of lifting under the action of the first driving mechanism to meet the requirements that the lower opening of the cake pressing cavity is closed after lifting and the turntable can carry the tea cake without obstruction during the subsequent rotation process; the specific design based on this function is well-known to those skilled in the art. Usually, two motors and corresponding transmission components can be used to separately manage the lifting and rotation functions, which will not be elaborated here. Similarly, as a variation, if the first driving mechanism uses a circulating belt, the opening and closing changes with the tea carving mold on the belt can be achieved by adjusting the vertical displacement of the cake pressing cavity.

[0041] Embodiment 2

[0042] Based on the same technical concept as the above Embodiment 1, this embodiment discloses an intelligent control method for a tea cake press, as Figure 2 shown, including:

[0043] Step S21: Input the volume calibration amounts corresponding to each tea carving mold on the turntable; at least two series of tea carving molds with different contents and volume calibration amounts are arranged at intervals on the turntable; the content of each tea carving mold consists of shapes, patterns, and / or characters; and there is a neighboring backup for the tea carving molds with the same content so that the arrangement of two different tea carving molds A and B is AABB; the turntable is driven to rotate forward and backward by the third driving mechanism.

[0044] Step S22: Establish the mapping relationship between each cake pressing cavity and the tea carving mold so that during the forward and backward rotation switching of the third driving mechanism, any cake pressing cavity synchronously switches the alignment with the tea carving molds with the same content that are the main and backup ones; and calculate the target height required for the extrusion force application surface that slides up and down in the cake pressing cavity to achieve the same density for a series of tea cakes according to the target weight of the currently pressed tea cake and the volume calibration amounts corresponding to each tea carving mold. The extrusion force application surface is driven by the fourth driving mechanism.

[0045] In this embodiment, each cake pressing cavity is fixed on the workbench, and the number of supporting groups composed of the cake pressing cavity and the fourth driving mechanism set on the third driving mechanism is an odd number group arranged at intervals with the tea carving molds.

[0046] In this step, the function of the fourth driving mechanism is analogous to that of the second driving mechanism in Embodiment 1; the function of the third driving mechanism is analogous to that of the first driving mechanism in Embodiment 1. Similarly, the third driving mechanism can be provided with components for lifting the turntable to meet the requirements that the lower opening of the cake pressing cavity is closed after lifting and the turntable can carry the tea cake without obstruction during the rotation process.

[0047] Step S23: After determining that the tea leaves weighed according to the target weight and then steam-treated are loaded into each cake pressing cavity, command each fourth driving mechanism to drive the extrusion application surface to slide downward to the corresponding target height and then start timing.

[0048] Step S24: After the pressing time reaches the set extrusion duration, command the fourth driving mechanism to drive the extrusion application surface to slide upward to the default position. Then, after demolding, command the third driving mechanism to act so that the backup tea carving mold is aligned with the cake pressing cavity and feed materials into the cake pressing cavity, and return to step S22 to start the next cycle until the target task is completed.

[0049] Preferably, air ducts driven by the same blower are deployed between adjacent supporting groups composed of the cake pressing cavity and the fourth driving mechanism. Each air duct is only opened during the extrusion duration corresponding to the pressing time, so that in the tea carving molds with each other as the main and backup, while one is shaping the tea cake, the other is synchronously cleaning the tea cake after demolding. Further, each tea carving mold is provided with a circular table side surface for alignment with the cake pressing cavity, and the turntable is provided with at least one drain port or drain groove lower than the bottom surface of each circular table, and the flow direction of the drain port or drain groove is the same as the air outlet direction of the air duct.

[0050] In this embodiment, the specific structure of the cake pressing cavity, the processing method of the volume calibration amount, the relationship between mass, volume and density, etc. are the same as those in Embodiment 1 and will not be elaborated.

When the processor executes the computer program, it implements the corresponding method in any of the above embodiments.

[0053] In summary, the intelligent control method and system of the tea cake press respectively disclosed in the above embodiments of the present invention have at least the following beneficial effects:

[0054] 1. The method of Embodiment 1 is applicable to making one tea cake at a time and forming a series with the same density in a time-division multiplexing manner. The method of Embodiment 2, on the other hand, works with multiple tea carving molds at the same time and can synchronously form a series with the same density. Both can be matched with the subsequent production process for storage and packaging by series.

[0055] 2. In the present invention, the fluffiness (or "compactness") of the tea cake is innovatively quantified as density in each of the above embodiments. During the calculation process, the relationship among mass, density, and volume follows existing common sense, making data processing simple and reliable. Furthermore, when the present invention faces different customer requirements, it can match the different density requirements of downstream customers at low cost and conveniently, with good compatibility and scalability.
