Description

Technical Field

[0001] The invention relates to the technical field of tea packaging, in particular to a tea pressing device for tea packaging. Background Art

[0002] The production and processing steps of tea vary depending on the type of tea, but can generally be summarized as several main stages such as picking, withering, killing green, rolling, fermentation, drying, grading, pressing, and packaging. The tea fermentation step is crucial, and fermentation directly affects the color, aroma, taste, health value, and other aspects of the tea. However, different types of tea (such as black tea, dark tea, oolong tea, etc.) have different fermentation methods. For example, when performing the black tea fermentation step, the rolled tea leaves need to be placed in an environment with suitable temperature and humidity (generally 20-30°C and 85%-95% relative humidity) to promote enzymatic oxidation reactions. The fermentation process can last from several hours to a whole day. During the fermentation process, the color change of the tea leaves needs to be checked regularly to ensure that the fermentation degree is moderate and to avoid excessive fermentation leading to quality degradation. The specific time depends on the required fermentation degree. Before the tea packaging step, the tea pressing step can press the loose tea into a specific shape (such as cakes, bricks, and tea blocks). The pressed tea cakes, tea bricks, or tea blocks not only help to preserve the tea leaves, but also make the tea leaves easier to manage and display during transportation and sales.

[0003] After searching, the Chinese invention patent with publication number CN 105053291 A discloses an automatic tea pressing device, including a main frame, on which a feeding device, a pressing device and a discharging device are arranged, the pressing device includes a turntable, on which a plurality of lower molds are arranged at intervals, and a gas supply mechanism for supplying moisture is arranged on the side of the turntable, and an upper mold is arranged on the side of the turntable, and a tea placement cavity is formed between the upper mold and the lower mold, and a tea pressing oil cylinder is fixedly connected to the top of the upper mold, and the discharging device includes a top holding oil cylinder, a forming tea conveyor and a manipulator mechanism. Compared with the prior art, the Chinese invention patent with publication number CN 105053291 A has a high degree of automation, improves the efficiency and quality of tea pressing and molding, and greatly reduces the maintenance rate of the equipment.

[0004] However, when the above-mentioned automatic tea pressing equipment performs steam softening before pressing, if the diameter of the through hole for steam to pass into the mold frame is too small, the steam flow rate will be limited; if the diameter of the through hole for steam to pass into the mold frame is too large, it will cause the material to easily scatter during the pressing process; and when discharging and conveying the tea blocks after pressing, it is necessary to perform the operation steps of pushing, clamping, transferring, and loosening the formed tea blocks, and the execution of multiple operation steps requires the control of a driver, which will cause the discharging and conveying operation of the formed tea blocks to be too cumbersome. Therefore, there is a need for a tea pressing device for tea packaging that can ensure the softening effect of the tea leaves, the pressing quality of the formed tea blocks, and can independently discharge and convey the formed tea blocks. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art, namely, the softening effect of tea leaves, the limited pressing quality of shaped tea blocks, and the overly complicated discharge and conveying operation of shaped tea blocks, and to propose a tea pressing device for tea packaging.

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

[0009] The above technical solution further includes:

[0010] The intermittent rotating disk is rotatably connected to the upper middle part of the device base by installing a driving seat, and the outer axis of the intermittent rotating disk is symmetrically fixedly connected with a centering limiter connected to the control cabinet, and the control cabinet is connected to the intermittent rotating disk, the quantitative feeding mechanism, the steam softening mechanism, the pressing and molding mechanism and the discharging conveying mechanism; after the control cabinet controls the intermittent rotating disk to rotate 90°, the centering limiter drives the quantitative feeding mechanism to feed, the steam softening mechanism to soften, and the pressing and molding mechanism to press through the control cabinet.

[0011] The intermittent stationary time of the intermittent rotating disk is greater than the feeding time of the quantitative feeding mechanism, the steam softening time of the steam softening mechanism and the pressing and molding time of the pressing and molding mechanism.

[0015] The press forming mechanism also includes an electric hydraulic cylinder group and two L-shaped hydraulic cylinders installed outside the device base, the input end of the electric hydraulic cylinder group is connected to the control cabinet, the two L-shaped hydraulic cylinders are fixedly connected through a T-shaped hydraulic cylinder, the insides of the two L-shaped hydraulic cylinders and the T-shaped hydraulic cylinder are fixedly connected to limit rings, and the insides of the two L-shaped hydraulic cylinders and the T-shaped hydraulic cylinder are respectively provided with an upper vertical piston rod, a lower vertical piston rod and a horizontal piston rod;

[0016] The upper vertical piston rod and the lower vertical piston rod respectively extend to the outside of the two L-shaped hydraulic cylinders and are respectively fixedly connected to the upper pressure module and the lower abutment template, and the horizontal piston rod extends to the outside of the T-shaped hydraulic cylinder and is fixedly connected to the output end of the electric hydraulic cylinder group;

[0017] After the control cabinet controls the intermittent rotating disk to rotate 90°, the centering limiter starts the electro-hydraulic cylinder group to shorten through the control cabinet, so that the upper pressing module presses down and the lower pressing template presses up to realize the pressing and forming of the tea leaves.

[0018] The discharging conveying mechanism also includes a bottom frame body fixedly connected to the bottom of the intermittent rotating disk, the outside of the bottom frame body is fixedly connected with an upper abutment ring and a lower abutment ring fixedly connected to each other, the outside of the lower abutment ring is provided with a passing groove located above the conveyor, and both sides of the passing groove are arranged as abutment slopes; when the abutment plate enters the passing groove through the abutment slope and abuts against the upper abutment ring, the connecting tube and the breathable tea cloth at the bottom of the molding mold tube are deflected and opened to discharge and convey the molded tea blocks to the packaging area.

[0019] The present invention has the following beneficial effects:

[0020] 1. In the present invention, four axially symmetrical forming mold cylinders are respectively located in the quantitative feeding mechanism, the steam softening mechanism, the pressing and forming mechanism, and the discharging and conveying mechanism, and the quantitative feeding process, the steam softening process, the pressing and forming process, and the discharging and conveying process are carried out simultaneously, and the control cabinet can control the intermittent rotating disk to rotate intermittently, so that the intermittent rotating disk can drive the forming mold cylinder to rotate 90° in sequence, so that the tea leaves can enter the tea packaging area after the quantitative feeding, steam softening, pressing and forming, and discharging and conveying processes.

[0021] 2. The breathable tea cloth arranged at the bottom of the molding mold cylinder in the present invention can ensure the smooth passage of steam, and the steam hood can abut the breathable tea cloth at the bottom of the molding mold cylinder upwards, so that the steam inside the steam hood can smoothly pass through the breathable tea cloth into the tea leaves inside the molding mold cylinder, thereby softening the tea leaves, and subsequently the lower pressing template abuts against the bottom of the molding mold cylinder, and the upper pressing module presses down the inside of the molding mold cylinder to achieve the pressing of the tea leaves, thereby ensuring the softening effect of the tea leaves and the pressing quality of the molded tea blocks.

[0022] 3. When the steam softening mechanism in the present invention reaches a preset time value, the electromagnetic block is powered off and the micro motor is powered on. When the electromagnetic block is powered off, the steam hood is reset and no longer abuts against the bottom of the forming mold barrel, so as to prevent the steam hood from affecting the intermittent rotating disk to drive the forming mold barrel to rotate 90° for position change. When the micro motor is started, it drives the axially symmetrical fan blades to rotate to a horizontal state through the bevel gear ring and the axially symmetrical bevel gear to completely close the steam hood, so as to prevent the steam softening mechanism from over-softening the tea leaves.

[0023] 4. The breathable tea cloth in the present invention is rotatably connected to the bottom of the molding mold cylinder through a connecting cylinder. When the molding mold cylinder follows the intermittent rotating disk to rotate into the discharging and conveying station, the abutment plate connected to the connecting cylinder can enter the groove through the abutment slope and abut with the upper abutment ring, so that the connecting cylinder and the breathable tea cloth at the bottom of the molding mold cylinder are deflected and opened, so that the molded tea blocks inside the molding mold cylinder are discharged and conveyed to the packaging area, and then closed and reset autonomously through the lower abutment ring, that is, the molded tea blocks can be discharged and conveyed autonomously without the need for excessive operating steps.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Embodiment 1

[0036] like Figure 1-Figure 9 As shown, a tea pressing device for tea packaging proposed by the present invention comprises a device base 1 and an intermittent rotating disk 2 installed above the device base 1, a quantitative feeding mechanism 30, a steam softening mechanism 40, a pressing and molding mechanism 50, a discharging and conveying mechanism 60, and a control cabinet 7. The intermittent rotating disk 2 is rotatably connected to the upper middle part of the device base 1 by installing a driving seat, and the outer axis of the intermittent rotating disk 2 is symmetrically fixedly connected to a molding mold cylinder 8, and a breathable tea cloth 9 is arranged at the bottom of the molding mold cylinder 8. The outer axis of the intermittent rotating disk 2 is symmetrically fixedly connected to a centering limiter connected to the control cabinet 7. The control cabinet 7 is connected with the intermittent rotating disk 2, the quantitative feeding mechanism 30, the steam softening mechanism 40, the pressing and molding mechanism 50 and the discharging conveying mechanism 60. The intermittent static time of the intermittent rotating disk 2 is greater than the feeding and mold feeding time of the quantitative feeding mechanism 30, the steam softening time of the steam softening mechanism 40 and the pressing and molding time of the pressing and molding mechanism 50. After the control cabinet 7 controls the intermittent rotating disk 2 to rotate 90°, the centering limiter drives the quantitative feeding mechanism 30 to feed, the steam softening mechanism 40 to soften, and the pressing and molding mechanism 50 to press through the control cabinet 7;

[0037] The quantitative feeding mechanism 30 includes a quantitative tube 31 located above the molding die barrel 8 and used for quantitative feeding, and the steam softening mechanism 40 includes a steam hood 41 located below the molding die barrel 8 and used for passing steam. The bottom of the steam hood 41 is connected to the steam generator through a threaded delivery pipe. The control cabinet 7 can control the steam flow rate and steam temperature of the steam generator. The other structures and connection methods included in the quantitative feeding mechanism 30, the steam softening mechanism 40 and the control cabinet 7 all adopt the existing technology, so they are not described in detail in this embodiment;

[0038] A fixing frame 42 is arranged outside the steam hood 41, and an electromagnetic block 43 connected to the control cabinet 7 is fixedly connected to the top of the fixing frame 42, and a magnetic block 44 fixedly connected to the steam hood 41 is slidably connected to the outside of the fixing frame 42. After the control cabinet 7 controls the intermittent rotating disk 2 to rotate 90°, the centering limiter energizes the electromagnetic block 43 through the control cabinet 7. When the electromagnetic block 43 is energized, the magnetic block 44 is attracted and the steam hood 41 is driven to abut against the upper molding die 8 upward, so that the steam inside the steam hood 41 enters the tea leaves inside the molding die 8 through the breathable tea cloth 9 to soften the tea leaves.

[0039] A timer connected to the control cabinet 7 is arranged outside the steam hood 41. After the control cabinet 7 controls the intermittent rotating disk 2 to rotate 90°, the centering limiter sets the timer through the control cabinet 7. When the timer reaches the preset time value, the electromagnetic block 43 can be powered off. An opening and closing member 450 capable of adjusting the amount of steam introduced is installed outside the steam hood 41. The micro motor 454 in the opening and closing member 450 is opened and closed synchronously with the electromagnetic block 43. A pressure relief valve 46 is installed outside the steam hood 41. If the steam softening time of the steam softening mechanism 40 is less than the feeding time of the quantitative feeding mechanism 30 or the pressing time of the pressing and molding mechanism 50, when the timer reaches the preset time value, the steam hood 41 is reset and the steam hood 41 is closed through the opening and closing member 450.

[0040] The opening and closing member 450 includes a mounting frame 451 mounted inside the steam cover 41, the outer portion of the mounting frame 451 is axially symmetrically connected to a rotating shaft 452, the outer portion of the rotating shaft 452 is fixedly connected to a fan blade 453 located inside the steam cover 41, the axially symmetrical fan blade 453 rotates to a vertical state to fully open the steam cover 41, and the axially symmetrical fan blade 453 rotates to a horizontal state to fully close the steam cover 41, and the opening and closing member 450 also includes a micro motor 454 mounted outside the steam cover 41 and a rotating connection A bevel gear ring 455 is connected to the outside of the steam hood 41, the end of the rotating shaft 452 extends to the outside of the steam hood 41 and is fixedly connected with a bevel gear 456 meshing with the bevel gear ring 455, the input end of the micro motor 454 is connected to the control cabinet 7, and the output end of the micro motor 454 is fixedly connected to a bevel gear 456. When the steam softening time of the steam softening mechanism 40 reaches a preset time value, the micro motor 454 starts to drive the axially symmetrical fan blades 453 to rotate to a horizontal state to completely close the steam hood 41;

[0041] The pressing and forming mechanism 50 includes an upper pressing module 51 and a lower abutting template 52 located above and below the forming mold cylinder 8. The upper pressing module 51 can press down and cooperate with the lower abutting template 52 abutting against the bottom of the connecting cylinder 62 to press and form the softened tea leaves inside the forming mold cylinder 8. The pressing and forming mechanism 50 also includes an electric hydraulic cylinder group 53 and two L-shaped hydraulic cylinders 54 installed outside the device base 1. The input end of the electric hydraulic cylinder group 53 is connected to the control cabinet 7. The two L-shaped hydraulic cylinders 54 are fixedly connected through a T-shaped hydraulic cylinder 55. The insides of the two L-shaped hydraulic cylinders 54 and the T-shaped hydraulic cylinder 55 are fixedly connected to a limiting ring 56. The two L-shaped hydraulic cylinders 54 and the T-shaped hydraulic cylinder 55 are fixedly connected to the limiting ring 56. An upper vertical piston rod 57, a lower vertical piston rod 58 and a horizontal piston rod 59 are respectively arranged inside. The upper vertical piston rod 57 and the lower vertical piston rod 58 extend to the outside of the two L-shaped hydraulic cylinders 54 respectively and are fixedly connected to the upper pressing module 51 and the lower abutment template 52 respectively. The horizontal piston rod 59 extends to the outside of the T-shaped hydraulic cylinder 55 and is fixedly connected to the output end of the electric hydraulic cylinder group 53. After the control cabinet 7 controls the intermittent rotating disk 2 to rotate 90°, the centering limiter starts the electric hydraulic cylinder group 53 to shorten through the control cabinet 7, so that the horizontal piston rod 59 enters the inside of the T-shaped hydraulic cylinder 55, so that the upper pressing module 51 is pressed down and the lower abutment template 52 is pressed up to realize the pressing and molding of tea leaves.

[0042] The working principle of this embodiment is as follows: Figure 1As shown, the four axisymmetric forming mold cylinders 8 are respectively located in the metering feeding mechanism 30, the steam softening mechanism 40, the pressing and forming mechanism 50, and the discharging and conveying mechanism 60, and simultaneously carry out the processes of feeding into the mold, steam softening, pressing and forming, and discharging and conveying. Moreover, the control cabinet 7 can control the intermittent rotating disk 2 to rotate intermittently, so that the intermittent rotating disk 2 can drive the forming mold cylinder 8 to rotate 90° in sequence, so that the tea can enter the packaging area of the tea after passing through the processes of metering feeding, steam softening, pressing and forming, and discharging and conveying;

[0043] When carrying out the process of feeding into the mold, the metering tube 31 in the metering feeding mechanism 30 can add a certain amount of tea into the interior of the forming mold cylinder 8. This process of feeding into the mold is no different from the process of feeding into the mold in the prior art and will not be elaborated;

[0044] When carrying out the steam softening process, the electromagnet block 43 in the steam softening mechanism 40 can be electrified to adsorb the magnetic attraction block 44, so that the steam hood 41 abuts upward against the breathable tea cloth 9 at the bottom of the forming mold cylinder 8, so that the steam inside the steam hood 41 can enter the tea inside the forming mold cylinder 8 through the breathable tea cloth 9, thus realizing the softening of the tea. At the same time, the timer in the steam softening mechanism 40 can be electrified to time. If the steam softening time of the steam softening mechanism 40 is less than the feeding into the mold time of the metering feeding mechanism 30 or the pressing and forming time of the pressing and forming mechanism 50, when the timer reaches the preset value, it will cut off the power supply to the electromagnet block 43 and energize the micro motor 454. When the electromagnet block 43 is powered off, the steam hood 41 will reset and no longer abut against the bottom of the forming mold cylinder 8, so as to prevent the steam hood 41 from affecting the rotation of the forming mold cylinder 8 driven by the intermittent rotating disk 2 by 90° for position change. When the micro motor 454 starts, it will drive the axisymmetric fan blades 453 to rotate to the horizontal state through the bevel gear ring 455 and the axisymmetric bevel gears 456 to completely close the steam hood 41, so as to prevent over softening of the tea. After that, the steam will be discharged through the pressure relief valve 46;

[0045] When carrying out the pressing and forming process, the electro-hydraulic cylinder group 53 in the pressing and forming mechanism 50 can shorten and drive the horizontal piston rod 59 into the interior of the T-shaped hydraulic cylinder 55, so that the hydraulic oil inside the T-shaped hydraulic cylinder 55 is squeezed into the interiors of the two L-shaped hydraulic cylinders 54, so that the upper vertical piston rod 57 and the lower vertical piston rod 58 approach each other, so that the lower abutting template 52 abuts against the bottom of the forming mold cylinder 8, and the upper pressing module 51 presses the softened tea inside the forming mold cylinder 8, thus realizing the pressing of the tea.

[0046] The main difference between this embodiment and the prior art is that the breathable tea cloth 9 arranged at the bottom of the molding cylinder 8 in this embodiment can ensure the smooth passage of steam, and the steam hood 41 can upwardly abut the breathable tea cloth 9 at the bottom of the molding cylinder 8, so that the steam inside the steam hood 41 can smoothly pass through the breathable tea cloth 9 into the tea leaves inside the molding cylinder 8, thereby softening the tea leaves, and subsequently the lower abutting template 52 abuts against the bottom of the molding cylinder 8, and the upper pressing module 51 presses down the inside of the molding cylinder 8 to achieve the pressing of the tea leaves, thereby ensuring the softening effect of the tea leaves and the pressing quality of the shaped tea blocks 10.

[0047] Embodiment 2

[0048] like Figure 1-Figure 3 and Figure 6-Figure 9 As shown, based on the first embodiment, the discharging conveying mechanism 60 includes a conveyor 61 located below the forming mold cylinder 8 and used to convey the formed tea block 10, and a connecting cylinder 62 axially symmetrically connected to the bottom of the intermittent rotating disk 2, the connecting cylinder 62 can be rotatably abutted against the bottom of the forming mold cylinder 8, the breathable tea cloth 9 is fixedly connected to the bottom of the connecting cylinder 62, and the outside of the connecting cylinder 62 is fixedly connected with an abutment plate 63;

[0049] The discharging conveying mechanism 60 also includes a bottom frame body 64 fixedly connected to the bottom of the intermittent rotating disk 2, and the outside of the bottom frame body 64 is fixedly connected with an upper abutment ring 65 and a lower abutment ring 66 fixedly connected to each other, and the outside of the lower abutment ring 66 is provided with a through groove 67 located above the conveyor 61, and both sides of the through groove 67 are arranged with abutment slopes 68. When the abutment plate 63 enters the through groove 67 through the abutment slope 68 and abuts with the upper abutment ring 65, the connecting tube 62 and the breathable tea cloth 9 at the bottom of the molding mold cylinder 8 are deflected and opened to discharge and convey the molded tea block 10 to the packaging area, and when the abutment plate 63 abuts with the lower abutment ring 66 through the abutment slope 68, the connecting tube 62 and the breathable tea cloth 9 at the bottom of the molding mold cylinder 8 are deflected and closed to wait for the subsequent feeding and molding process.

[0050] The working principle of this embodiment is as follows: based on the first embodiment, when the discharging and conveying process is carried out, the intermittent rotating disk 2 can drive the forming mold cylinder 8 that has completed feeding, softening and pressing to enter the discharging and conveying station. During the process of the forming mold cylinder 8 entering the discharging and conveying station, the abutment plate 63 can enter the groove 67 through the abutment slope 68 and abut against the upper abutment ring 65. When the abutment plate 63 abuts against the upper abutment ring 65, the connecting tube 62 and the breathable tea cloth 9 at the bottom of the forming mold cylinder 8 are deflected and opened, so that the formed tea blocks 10 inside the forming mold cylinder 8 are discharged to the conveyor 61, and the formed tea blocks 10 on the conveyor 61 are transported to the packaging area.

[0051] When the material feeding and molding process is carried out, the intermittent rotating disk 2 can drive the molding mold cylinder 8 to enter the material feeding and molding station. When the molding mold cylinder 8 enters the material feeding and molding station, the abutment plate 63 can abut against the lower abutment ring 66 through the abutment slope 68. When the abutment plate 63 abuts against the lower abutment ring 66, the connecting tube 62 and the breathable tea cloth 9 at the bottom of the molding mold cylinder 8 are deflected and closed, waiting for the subsequent material feeding and molding process.

[0052] The main difference between the present embodiment and the prior art is that the breathable tea cloth 9 in the present embodiment is rotatably connected to the bottom of the molding mold cylinder 8 through the connecting cylinder 62. When the molding mold cylinder 8 follows the intermittent rotating disk 2 to rotate into the discharging and conveying station, the abutment plate 63 connected to the connecting cylinder 62 can enter the groove 67 through the abutment slope 68 and abut with the upper abutment ring 65, so that the connecting cylinder 62 and the breathable tea cloth 9 at the bottom of the molding mold cylinder 8 are deflected and opened, so that the molded tea block 10 inside the molding mold cylinder 8 is discharged and conveyed to the packaging area, and then automatically closed and reset through the lower abutment ring 66, that is, the molded tea block 10 can be discharged and conveyed autonomously without performing too many operating steps.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
