Description

Technical Field

[0001] The invention relates to the technical field of tea brick production, and in particular to a process and equipment for preparing a tea brick that is convenient to be broken apart by hand. Background Art

[0002] Tea bricks are a type of long-fermented tea, usually pressed into sizes of 0.1-3 kg. Tea bricks are easy to transport and store for a long time. The loose tea used to make tea bricks has been fermented before molding and has a high water content. The loose tea is then steamed with high-temperature steam, and the tea leaves are placed in a special tea brick mold and pressed into shape through mechanical pressing. Tea bricks are usually made from tea leaves, tea stems, and sometimes tea powder.

[0003] In the prior art, a large number of articles on tea brick production and corresponding devices are disclosed. For example, a Chinese patent with publication number CN108991159A discloses a tea brick preparation process, including a supporting mechanism, the top of the supporting mechanism is connected to a control mechanism through a hydraulic cylinder, the side of the supporting mechanism is fixedly connected to a rotating mechanism, the top edge of the rotating mechanism is equidistantly fixedly connected to the inside of the supporting mechanism with a first pressing mechanism for realizing feeding and tea brick pressing, the hydraulic cylinder is engaged with the first pressing mechanism, a second pressing mechanism corresponding to the first pressing mechanism is provided inside the supporting mechanism, and a downward pressing mechanism for pressing semicircular tea bricks is provided inside the second pressing mechanism.

[0004] When the above-mentioned prior art is in use, tea leaves are placed in the placement groove of the first pressing mechanism, and then the rotating mechanism cooperates with the hydraulic cylinder to press the tea leaves inside the placement groove one by one. After the pressing is completed, the next tea brick is pressed. The pressed tea brick is taken down by the loading personnel and replaced with a new tea brick for pressing.

[0005] However, in the process of making tea bricks using the above-mentioned prior art, there are still the following shortcomings:

[0006] 1. Since the tea bricks pressed by the above-mentioned prior art are a whole piece and the hardness of the tea bricks is relatively large, it is difficult to easily break them apart by hand when brewing tea. Special tools or force are required to pry them apart, and it is easy to cause hand injuries to the user when prying the tea apart. In addition, the size and weight of the small pieces of tea after prying apart cannot be guaranteed to be consistent, which has a certain impact on the taste of the brewed tea, and it is difficult to pry apart the tea bricks and quickly brew tea for drinking when carrying them out.

[0007] 2. Furthermore, since the diameter of the placement groove provided by the above-mentioned prior art cannot be adjusted, the pressed tea bricks are of a specified size, so that only tea bricks of a specified size can be produced, and tea bricks of different specifications cannot be produced, which leads to limitations and makes it difficult to adapt to market demand.

[0047] The following is combined with Figure 1-Figure 13 Embodiments of the present invention are described in detail.

[0048] The embodiment of the present application discloses a process and equipment for preparing a tea brick that is easy to break apart by hand. It is explained that the process and equipment for preparing a tea brick that is easy to break apart by hand are mainly used in the process of making tea bricks. In terms of technical effect, a secondary pressing and forming scheme is adopted. First, tea leaves are pressed into small pieces of dried tea leaves. Then, the dried tea leaves are pieced together into complete rectangular tea pieces. Then, multiple rectangular tea pieces are overlapped and pressed into multi-layer, multi-row, and multi-column tea bricks, so that they can be easily broken apart. The size and weight of each piece of tea broken off are basically the same, which can ensure the consistency of the taste of each cup of tea and is easy to carry outside. Especially in the process of piecing together the dried tea leaves into rectangular tea pieces, By pouring hot tea juice on the tea stems, they can be bonded together after being pieced together and are not easy to fall off, and the tea stems can be heated during the pieced together process, so that multiple tea stems can be quickly bonded together with the hot tea juice to form stable rectangular tea pieces; further, the tea brick preparation process and equipment that are easy to break apart by hand can also cyclically execute the pressing of tea stems, automatic pouring of tea stems, and automatic gathering and bonding of multiple tea stems into complete rectangular tea pieces, thereby realizing automatic pressing of tea stems, and automatically collecting the pressed rectangular tea pieces, without the need for manual collection, avoiding safety hazards for workers when taking tea stems.

[0049] Embodiment 1:

[0050] Reference Figure 2 and Figure 3 As shown, a tea brick preparation device that is easy to break apart by hand includes a workbench 1, a pressing device 2 is arranged on the upper end of the workbench 1, the pressing device 2 includes a mold base 21 installed on the upper end of the workbench 1 and a lower pressing mold 22 located above the mold base 21, a collecting device 3 is arranged between the workbench 1 and the pressing device 2, the collecting device 3 includes a control unit 31 for controlling the mold base 21 to move along the length direction of the workbench 1 and a discharge port 32 for collecting the pressed dried tea and opening it at the upper end of the workbench 1, the discharge port 32 and the mold base 21 are arranged along the length direction of the workbench 1, and are symmetrical in the width direction of the workbench 1.

[0051] In the specific implementation process, the tea leaves are first evenly placed in the mold seat 21, and then the pressing device 2 controls the lower pressing mold 22 to move downward and cooperate with the mold seat 21 to press the tea leaves into small pieces of dried tea. After the pressing of the dried tea leaves is completed, the mold seat 21 is moved to above the discharge port 32 through the collecting device 3 and cooperates with the control unit 31 to turn the mold seat 21 180 degrees to pour out the dried tea leaves. Then the collecting device 3 squeezes the dried tea leaves into a complete rectangular tea piece in a patchwork manner, which is convenient for the later production of tea bricks.

[0052] Continue to refer to Figure 2 and Figure 3 As shown, in order to facilitate the use of tea bricks, the tea bricks produced in the present application are composed of multiple small pieces of dried tea, so they can be easily broken apart when drinking tea. Based on this, the tea leaves need to be pressed into small pieces of dried tea first, so a pressing device 2 is provided in this embodiment. Specifically, the pressing device 2 also includes a receiving plate 24 installed above the mold seat 21 through a support rod 23, and a hydraulic cylinder 25 is provided on the upper end of the receiving plate 24. The telescopic end of the bottom of the hydraulic cylinder 25 passes through the receiving plate 24 and is installed with a lower pressing die 22 through a lifting plate 26. Two guide columns 27 that slide through the lifting plate 26 are symmetrically arranged between the receiving plate 24 and the workbench 1. The lifting plate 26 can be limited by the guide columns 27 so that it always maintains a horizontal state during the lifting process.

[0053] Furthermore, in this embodiment, the upper end of the mold base 21 has a plurality of accommodating groups equidistantly distributed along its width direction, each accommodating group includes a plurality of placement holes 211 equidistantly arranged along the length direction of the mold base 21, and the placement holes 211 of two adjacent accommodating groups are arranged vertically, so that the dried tea leaves can be arranged criss-cross when they are pieced together, thereby giving them better adhesion and preventing them from falling off; a plurality of lower pressing blocks corresponding to the positions of the placement holes 211 are detachably installed at the bottom of the lower pressing mold 22.

[0054] In the specific implementation process, the tea leaves that need to be pressed into dried tea leaves are first evenly placed in a plurality of placement holes 211, and then the hydraulic cylinder 25 is started. The hydraulic cylinder 25 drives the lifting plate 26 and the lower pressing die 22 to move downward as a whole, so that the lower pressing die 22 drives the lower pressing block to be inserted into the placement hole 211 and press and shape the tea leaves inside, so that the tea leaves are pressed into small pieces of dried tea leaves, and then the hydraulic cylinder 25 drives the lifting plate 26 and the lower pressing die 22 to move upward as a whole.

[0055] In addition, by removing the lower pressing block at the bottom periphery of the lower pressing mold 22 and inserting it into the placement hole 211 corresponding to its position, the amount of dried tea leaves can be reduced, that is, the area of ​​the assembled rectangular tea pieces can be reduced, so that tea bricks of different specifications can be produced according to market demand.

[0056] Continue to refer to Figure 3 As shown, in order to facilitate the collection of the pressed dried tea leaves, in this embodiment, the collecting device 3 also includes guide bars 33 installed on the upper end of the workbench 1 and symmetrically arranged along its width direction, and a horizontal plate 34 is slidably connected between the two guide bars 33. The horizontal plate 34 is provided with an opening corresponding to the position of the discharge port 32. Two vertical plates 35 are symmetrically arranged on the upper end of the horizontal plate 34 along its moving direction, and the mold base 21 is installed between the two vertical plates 35.

[0057] Furthermore, in this embodiment, a positioning cylinder 36 is installed via a bracket on the upper end of the workbench 1 away from the discharge port 32 , and the telescopic end of the positioning cylinder 36 is connected to the vertical plate 35 away from the discharge port 32 .

[0058] In the initial state, the horizontal plate 34 drives the mold base 21 to be located below the lower pressing mold 22 through the vertical plate 35. At this time, the placement hole 211 corresponds to the position between the lower pressing block.

[0059] In the specific implementation process, after the pressing of the dried tea leaves is completed, the positioning cylinder 36 is started, and the positioning cylinder 36 applies a pushing force to the vertical plate 35. The vertical plate 35 drives the mold base 21 and the horizontal plate 34 to move along the length direction of the guide strip 33, so that the mold base 21 stops when it moves to above the discharge port 32; then, under the action of the control unit 31, the mold base 21 is controlled to flip 180 degrees to facilitate pouring the dried tea leaves into the discharge port 32.

[0060] Reference Figure 3 and Figure 4 As shown, since the pressed dried tea leaves are all located in the placement hole 211, it would take a lot of time to take them out manually. Based on this, a control unit 31 is provided in this embodiment to control the flipping of the mold base 21 and pour out the dried tea leaves in the placement hole 211. Specifically, the control unit 31 includes support blocks 311 installed on both sides of the width direction of the vertical plate 35. The two support blocks 311 on the same side of the mold base 21 are connected to each other by a control disc 312 that rotates together. The control disc 312 can guide the flipping of the mold base 21 so that the mold base 21 can only be flipped along its moving direction, thereby avoiding the mold flipping angle deviation and making it difficult to pour out the dried tea leaves; the rotation direction of the control disc 312 is the same as the moving direction of the mold base 21. A connecting shaft 313 connected to the outer wall of the mold base 21 is passed through the control disc 312, and the outer wall of the connecting shaft 313 is sleeved with a stabilizing plate 314 connected to the top of the horizontal plate 34.

[0061] Furthermore, in this embodiment, the control unit 31 also includes a gear 315 sleeved on the outer wall of the connecting shaft 313, and a rack plate 317 meshing with the gear 315 is provided on the side of the upper end of the workbench 1 close to the discharge port 32 through a mounting plate 316; a rectangular block 318 is sleeved on the outer wall of the connecting shaft 313 located on the side of the gear 315 close to the mold base 21, and a gear bar 319 is installed at the upper end of the guide bar 33 located at the initial position of the mold base 21, which slides against the bottom of the rectangular block 318.

[0062] During the specific implementation process, when the horizontal plate 34 drives the mold base 21 to move to the side close to the discharge port 32, the mold base 21 drives the connecting shaft 313, the gear 315 and the rectangular block 318 to move synchronously as a whole. When the gear 315 is engaged with the rack plate 317, the rack plate 317 controls the connecting shaft 313 and the mold base 21 to start rotating through the gear 315, so that the mold base 21 continues to rotate during the subsequent movement process; when the mold base 21 moves to above the discharge port 32, the mold base 21 is controlled to flip 180 degrees through the coordination between the gear 315 and the rack plate 317, so that the pressed dried tea in the upper placement hole 211 is poured downward; this facilitates the quick pouring of the dried tea without manual picking.

[0063] Then the horizontal plate 34 drives the mold base 21 to move to the side away from the discharge port 32 to reset, and the mold base 21 is controlled to rotate in the opposite direction through the cooperation between the gear 315 and the rack plate 317. Then the rectangular block 318 conflicts with the shift bar 319 and controls the mold base 21 to reset.

[0064] It should be noted that there is a gap at the junction of the shift bar 319 and the rack plate 317. The gap is used to prevent the mold base 21 from rotating when the gear 315 and the rack plate 317 are separated, and to facilitate the mold base 21 to be smoothly driven to reset when the rectangular block 318 conflicts with the shift bar 319.

[0065] Reference Figure 5 , Figure 6 and Figure 7 As shown, in order to facilitate piecing together the dried tea leaves poured out of the mold base 21 into a complete rectangular tea piece, the collecting device 3 in this embodiment also includes a molding unit 37, which includes a bottom support box 371 installed at the lower end of the workbench 1, and a partition 372 is arranged in the middle of the bottom support box 371. The side of the partition 372 away from the discharge port 32 is a storage chamber, and the storage chamber is used to store hot tea juice. By pouring hot tea juice on the dried tea leaves, the pieces can be bonded together after piecing together and are not easy to fall off. In addition, the use of hot tea juice will not affect the taste of the tea and the safety of drinking; the other side of the partition 372 is a collection chamber for temporarily storing the rectangular tea pieces after piecing together, the collection chamber is connected to the discharge port 32, and the side of the collection chamber away from the partition 372 is hinged with a warehouse door 373.

[0066] Furthermore, in this embodiment, the molding unit 37 further includes two support plates 374 hinged to the inner walls on both sides of the length direction of the material discharge port 32, and two positioning plates 375 are symmetrically arranged at the lower end of the workbench 1 along the width direction of the material discharge port 32, and a telescopic cylinder 376 is hinged between the positioning plate 375 and the bottom of the support plate 374; in the initial state, the telescopic end of the telescopic cylinder 376 is in an extended state, and at this time the support plate 374 is in a horizontal state (in Figure 5Two mounting grooves are symmetrically provided inside the workbench 1 along the length and width directions of the material discharge opening 32, and a linkage cylinder 377 is arranged in the mounting groove. The telescopic ends of the linkage cylinder 377 both point to the material discharge opening 32 and are provided with a pushing plate 378 which is slidably docked on the upper end of the supporting plate 374. Electric heating wires (not shown in the figure) are arranged inside the supporting plate 374 and the pushing plate 378.

[0067] Furthermore, in this embodiment, the molding unit 37 also includes two water pumping pipes 379 which are symmetrically arranged along the width direction of the discharge port 32 and pass through the mounting plate 316. A discharge pipe 380 is installed at one end of the water pumping pipe 379 close to the discharge port 32. A plurality of nozzles 381 are equidistantly arranged along the length direction on one side of the discharge pipe 380 close to the discharge port 32. The end of the water pumping pipe 379 away from the discharge pipe 380 passes through the workbench 1 and extends to the interior of the storage chamber.

[0068] During the specific implementation process, the pressed tea leaves are poured downward by the mold seat 21 to the upper end of the supporting plate 374. At this time, the multiple tea leaves on the upper end of the supporting plate 374 are arranged in a matrix, and there is a certain distance between adjacent tea leaves; at this time, the telescopic cylinders 376 on both sides of the length direction of the discharge port 32 are started, and the telescopic cylinders 376 drive the pushing plates 378 to push and gather the tea leaves to the middle of the supporting plate 374, so that the tea leaves form multiple columns equidistantly distributed along the length direction of the discharge port 32, and then the telescopic cylinders 376 drive the pushing plates 378 to reset; then the telescopic cylinders 376 on both sides of the width direction of the discharge port 32 are started, and the telescopic cylinders 376 drive the pushing plates 378 to push and gather multiple columns of tea leaves to the middle of the supporting plate 374 to form a complete rectangular tea piece, thereby realizing the rapid molding of multiple tea leaves.

[0069] At the same time, the nozzle 381 draws hot tea juice from the storage chamber and sprays it on the dried tea leaves, starting the electric heating wire so that the heated pushing plate 378 and the supporting plate 374 heat the dried tea leaves, so as to quickly bond multiple dried tea leaves together with the hot tea juice to form stable rectangular tea leaves.

[0070] After the rectangular tea leaves are made, the telescopic cylinder 376 is started, which drives the support plate 374 to rotate downward and open the feeding port 32, so that the rectangular tea leaves on the upper end fall downward into the collecting chamber, so that the workers can use external equipment to collect the rectangular tea leaves and press a specified number of rectangular tea leaves into tea bricks (in Figure 7 ).

[0071] In summary, repeating the above steps can enable the mold to move reciprocatingly through the mutual cooperation among the mold base 21, the lower pressing mold 22, the control unit 31 and the molding unit 37, during which the pressing of the dried tea leaves, the automatic pouring out of the dried tea leaves, the pushing and gathering of the dried tea leaves and the bonding of the dried tea leaves into complete rectangular tea pieces can be cyclically performed, thereby realizing the automatic pressing of the dried tea leaves, and the automatic collection of the pressed rectangular tea pieces without the need for manual collection, thereby avoiding safety hazards for workers when taking the dried tea leaves.

[0074] In the specific implementation process, after the mold base 21 is flipped over, the air pump 43 is started, and the air pump 43 quickly injects air into the air hole 41 through the air pipe 44, so that the air in the air hole 41 enters the through hole 42 and provides an extension force to the dried tea leaves in the placement hole 211, so that the dried tea leaves in the placement hole 211 can be quickly poured out, avoiding the safety hazard caused by manual removal, and can effectively prevent the dried tea leaves from remaining in the placement hole 211.

[0075] Embodiment 3:

[0076] Reference Fig.10 , Fig.11 , Fig.12 and Fig.13As shown, on the basis of Example 1, in order to further improve the bonding force between the dried tea leaves, it is not only necessary to arrange the adjacent dried tea leaves in the rectangular tea pieces in a criss-cross pattern, but also necessary to ensure that the dried tea leaves between the adjacent rectangular tea pieces are arranged in a criss-cross pattern. Based on this, an interlaced stacking device is also provided in this embodiment, which includes a plurality of pressure holes opened at the bottom of the mold base 21, and the pressure holes correspond to the positions of the placement holes 211, but the pressure holes and the placement holes 211 at the same position are arranged in an interlaced manner, so that the multiple dried tea leaves poured out of the placement holes 211 at the upper end of the mold base 21 and the multiple dried tea leaves poured out of the pressure holes are criss-crossed; two lower pressing dies 22 respectively matching the placement holes 211 and the pressure holes are installed at the lower end of the lifting plate 26 through a linkage plate 51, and a displacement plate slidably docked at the bottom of the linkage plate 51 is commonly provided at the upper ends of the two lower pressing dies 22, and a control cylinder 52 connected to the displacement plate is installed on one side of the linkage plate 51 in the length direction.

[0077] Furthermore, in this embodiment, the connecting shaft 313 is a telescopic shaft, and a section of the connecting shaft 313 away from the mold base 21 is an arc-shaped convex surface. A hemispherical block 54 abutting against the arc-shaped convex surface is installed on the side of the mounting plate 316 away from the discharge port 32 through a connecting frame 53, and the hemispherical block 54 is located at a position where the mold base 21 is flipped 180 degrees.

[0078] Furthermore, in the present embodiment, an L-shaped bar 55 is provided on one side of the mounting plate 316 close to the discharge port 32, a temporary storage groove is formed between the horizontal section of the L-shaped bar 55 and the rack plate 317, the distance between the vertical section of the L-shaped bar 55 and the rack plate 317 is greater than the thickness of the gear 315, and the top of the vertical section of the L-shaped bar 55 is flush with the top of the shift bar 319, and a reset bar 56 that slidably contacts the side wall of the rectangular block 318 is provided on the side of the shift bar 319 close to the mold base 21, the upper end of the reset bar 56 is higher than the shift bar 319, and the end of the reset bar 56 close to the L-shaped bar 55 is inclined toward the side close to the mold base 21.

[0079] In the specific implementation process, after the tea leaves in the placement hole 211 of the mold base 21 are pressed, the horizontal plate 34 drives the mold base 21 to move to the side close to the discharge port 32. When the mold base 21 moves to the top of the discharge port 32, the mold base 21 flips 180 degrees to pour out the tea leaves in the placement hole 211, and controls the pressure hole to be at the top; at the same time, the end of the connecting shaft 313 abuts against the hemispherical block 54 and drives the gear 315 and the rectangular block 318 to move as a whole to the side close to the mold base 21, so that the gear 315 and the rack plate 317 are staggered and moved into the temporary storage groove, and the rectangular block 318 abuts against the top of the vertical section of the L-shaped bar 55 (at Fig.13 As shown in the figure, when the mold base 21 moves to the side away from the discharge port 32 and resets, the pressure hole can be kept facing upward.

[0080] During this period, when the rectangular block 318 conflicts with the reset bar 56, it will drive the gear 315 to move as a whole to the side away from the mold base 21 and reset, so that the gear 315 and the rack plate 317 are in the same plane, so that when the mold base 21 moves to the side close to the discharge port 32 again, the gear 315 can mesh with the rack plate 317, thereby ensuring that the mold base 21 can be flipped 180 degrees every time it moves back and forth, and after the mold base 21 is flipped, it can maintain this state and move to the initial position to reset, so that interlaced rectangular tea pieces can be made in sequence, and there is no need to manually arrange and bond the tea leaves in a specified splicing method, and then it is convenient to press the multiple layers of rectangular tea pieces into a complete tea brick.

[0081] While the mold base 21 moves and resets, the control cylinder 52 is started, and the control cylinder 52 drives the linkage plate 51 and the two lower pressing molds 22 at its lower end to move as a whole, so that the lower pressing mold 22 matched with the pressure hole moves to above the mold base 21. At this time, it is convenient to press the tea leaves placed in the pressure hole into dried tea leaves, and the dried tea leaves poured out of the pressure hole and the dried tea leaves poured out of the placement hole 211 are arranged in a criss-cross pattern, so that the multi-layer rectangular tea leaves have sufficient bonding force and are not easy to fall off.

[0082] Reference Figure 1 As shown, in addition, the present application also provides a process for preparing a tea brick that is easy to break apart by hand, comprising the following steps:

[0083] S1: placing tea leaves: firstly, the tea leaves to be pressed into dried tea leaves are evenly placed in a plurality of placement holes 211 .

[0084] S2: Tea pressing: Start the hydraulic cylinder 25, which drives the lifting plate 26 and the lower pressing die 22 to move downward as a whole, so that the lower pressing die 22 drives the lower pressing block to be inserted into the placement hole 211 and press and shape the tea leaves inside, so that the tea leaves are pressed into small pieces of dried tea, and then the hydraulic cylinder 25 drives the lifting plate 26 and the lower pressing die 22 to move upward as a whole.

[0085] S3: Assembling dried tea leaves: Start the positioning cylinder 36, which applies a pushing force to the vertical plate 35. The vertical plate 35 drives the mold base 21 and the horizontal plate 34 to move along the length direction of the guide bar 33. The mold base 21 drives the connecting shaft 313, the gear 315 and the rectangular block 318 to move synchronously as a whole. When the gear 315 is meshed with the rack plate 317, the rack plate 317 controls the rotation of the connecting shaft 313 and the mold base 21 through the gear 315. The mold base 21 stops when it moves to above the discharge port 32. The mold base 21 is controlled to flip 180 degrees through the coordination between the gear 315 and the rack plate 317, so that the dried tea leaves pressed in the upper placement hole 211 are poured downward to the upper end of the supporting plate 374. Then the mold base 21 moves to the side away from the discharge port 32 and resets.

[0086] The multiple dried tea leaves on the upper end of the supporting plate 374 are arranged in a matrix, and there is a certain distance between adjacent dried tea leaves. Then, the telescopic cylinders 376 on both sides of the length direction and the width direction of the discharge port 32 are started in turn. The telescopic cylinders 376 respectively drive the pushing plates 378 to push the dried tea leaves toward the middle of the supporting plate 374 to form a complete rectangular tea piece. At the same time, the nozzle 381 draws hot tea juice from the storage chamber and sprays it on the dried tea leaves, and starts the electric heating wire, so that the heated pushing plates 378 and the supporting plate 374 heat the dried tea leaves, so as to cooperate with the hot tea juice to quickly bond the multiple dried tea leaves to form a stable rectangular tea piece.

[0087] S4: Tea brick production: After the rectangular tea leaves are produced, the telescopic cylinder 376 is started. The telescopic cylinder 376 drives the supporting plate 374 to rotate downward and open the discharge port 32, so that the rectangular tea leaves on the upper end fall downward into the collecting chamber. Subsequently, a specified number of rectangular tea leaves are overlapped and placed, and then pressure is applied to press them into tea bricks.

[0088] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.

[0089] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
