Description

Technical Field

[0001] The utility model relates to the technical field of tea processing equipment, in particular to a tea flattening and forming machine. Background Art

[0002] After being picked, tea leaves need to go through the tea-making process in order to better bring out the aroma of the tea and enhance the taste of the tea. When scattered tea leaves are piled together, there will be a lot of gaps between them, resulting in the space not being well utilized when the tea is stored. Therefore, in order to increase the storage capacity of tea leaves, tea leaves are usually pressed into tea cakes to reduce storage costs.

[0003] When tea leaves are pressed into tea cakes, they need to be placed in a container and compressed using a compressor. However, due to the different shapes of tea leaves, the gaps between them cannot be controlled, which will result in the tea leaves in some areas being compressed while the tea leaves in other areas are still somewhat loose. In this way, the tea cakes need to be compressed a second time, which reduces the compression efficiency of the tea cakes. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a tea leaf flattening and forming machine so as to solve the technical problems mentioned in the above background technology.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions:

[0006] A tea leaf flattening and forming machine comprises a base, wherein the four corners of the top of the base are fixedly connected to support columns, the top of the support columns is connected to a cover plate, the top of the cover plate is fixedly connected to a hydraulic press, the output shaft of the hydraulic press passes through the cover plate and is connected to a compression mechanism, and the top of the base is located directly below the compression mechanism and is fixedly connected to a pressing table.

[0007] By adopting the above technical solution, the compression mechanism is set up to vibrate at a high frequency when compressing the tea leaves, and exert a high-frequency impact force on the tea cake, so that the tea cake is compressed more evenly and the compression efficiency is improved.

[0008] In a preferred example, the utility model can be further configured as follows: the compression mechanism includes an extrusion block, a casing and a vibration component, the top of the casing is fixedly connected to the output shaft of the hydraulic press, the bottom of the casing is provided with a slide groove, the extrusion block is slidably connected in the slide groove, and a vibration component is arranged between the extrusion block and the casing.

[0009] By adopting the above technical solution, when the extrusion block presses the tea leaves into tea cakes and cannot be compressed further, the extrusion block activates the vibration component, and uses the vibration component to drive the extrusion block to vibrate at a high frequency, thereby applying a high-frequency impact force to the tea cake, making the tea cake compressed more evenly and the pressing efficiency higher.

[0010] In a preferred example, the utility model can be further configured as follows: the vibration component includes a piston, a compression spring and a positioning unit, the piston is slidably arranged in the slide groove, the top and bottom of the piston are connected to compression springs, the compression spring located at the bottom of the piston is connected to the top of the extrusion block, the compression spring located at the top of the piston is connected to the inner top wall of the slide groove, and the outer wall of the shell is connected to a positioning unit for limiting the movement of the piston.

[0011] By adopting the above technical solution, the piston can be fixed by the provided positioning unit, so that the piston compresses the compression spring on one side, so that after the piston is released, the compression spring with a larger degree of compression pushes the piston to move and compresses the other compression spring, thereby reciprocatingly applying high-frequency impact force to the extrusion block.

[0012] In a preferred example, the utility model can be further configured as follows: the positioning unit includes a block, a support spring and a truncated cone, the outer wall of the shell is raised to form a truncated cone, a circular groove connected to the slide groove is provided in the truncated cone, a block is slidably connected in the circular groove, a support spring is provided between one side of the block and the circular groove, and a groove matching the block is provided on the outer wall of the piston.

[0013] By adopting the above technical solution, the provided clamping block can cooperate with the clamping groove on the outer wall of the piston to fix the piston, and the provided supporting spring is used to provide supporting force to the clamping block to ensure that the piston will not separate from the clamping block after being fixed.

[0014] In a preferred example, the utility model can be further configured as follows: the bottom of the cover plate is fixedly connected to a limiting column, and the top of the housing is provided with a through hole for avoiding the limiting column.

[0015] By adopting the above technical solution, a limit column is set up to squeeze the piston when the hydraulic press pulls the compression mechanism to reset, so that the piston squeezes the compression spring, thereby increasing the potential energy of the compression spring at the bottom of the piston, which is used to push the piston to vibrate at a high frequency when the piston is released.

[0016] In a preferred example, the utility model can be further configured as follows: an extrusion groove is opened on the top of the pressing table, and the opening of the extrusion groove is processed with a chamfer.

[0017] By adopting the above technical solution, the extrusion groove opened in the pressing table can be used to place tea leaves, making it easier for the compression mechanism to press the tea leaves into tea cakes, and the chamfer set at the opening of the extrusion groove can make it easier for the compression mechanism to enter the extrusion groove to press the tea leaves.

[0018] In summary, the utility model includes at least one of the following beneficial technical effects:

[0019] 1. This tea flattening and forming machine can apply high-frequency vibration to the pressed tea cakes when pressing the tea leaves through the provided compression mechanism, so that the tea cakes are compressed more evenly, thereby avoiding secondary processing of the tea cakes, thereby effectively improving the pressing efficiency of the tea cakes;

[0020] 2. This tea flattening and forming machine, by opening an extrusion groove on the pressing table, is convenient for placing the tea leaves to be flattened, and the chamfer set at the opening of the extrusion groove can guide the compression mechanism, so that the compression mechanism can enter the extrusion groove more accurately, thereby improving the production efficiency of tea cakes.

DETAILED DESCRIPTION

[0026] The utility model is further described in detail below in conjunction with the accompanying drawings. Example

[0027] Reference Figure 1 - Figure 3 The utility model discloses a tea flattening and forming machine, comprising a base 1, the four corners of the top of the base 1 are fixedly connected to support columns 2, the top of the support column 2 is connected to a cover plate 3, the top of the cover plate 3 is fixedly connected to a hydraulic press 4, the output shaft of the hydraulic press 4 passes through the cover plate 3 and is connected to a compression mechanism 5, and the top of the base 1 is located directly below the compression mechanism 5 and is fixedly connected to a pressing platform 6.

[0028] In this embodiment, the pressing table 6 provided can be used to place the tea leaves to be processed, and then the hydraulic press 4 is started to push the compression mechanism 5 downward to flatten the tea leaves. When the tea leaves are flattened to the point that the extrusion block 51 cannot move further downward, the pressure applied by the hydraulic press 4 will press the extrusion block 51 into the slide groove 7, so that the compression spring 532 located at the bottom of the piston 531 is squeezed by the extrusion block 51 and deformed, thereby increasing the supporting force of the compression spring 532 on the piston 531. When the supporting force is greater than the supporting force applied by the compression spring 532 to the block 533a, the piston 531 is pushed upward by the compression spring 532, thereby pressing the block 533a into the circular groove 8, separating the block 533a from the groove 9, and releasing the piston 531.

[0029] When the piston 531 is released, the supporting force applied to the piston 531 by the compression spring 532 at the bottom of the piston 531 is greater than the supporting force applied to the piston 531 by the compression spring 532 at the top of the piston 531. Therefore, the piston 531 is pushed upward by the compression spring 532 at the bottom until the supporting forces applied to the piston 531 by the two compression springs 532 remain the same. Then, the piston 531 will continue to move upward to squeeze the compression spring 532 at the top due to inertia, so that the supporting force applied to the piston 531 by the compression spring 532 at the top is greater than the supporting force applied to the piston 531 by the compression spring 532 at the bottom of the piston 531, so that the compression spring 532 at the top of the piston 531 pushes the piston 531 downward and squeezes the compression spring 532 at the bottom of the piston 531, and the piston 531 vibrates at a high frequency in the slide groove 7 in this reciprocating manner.

[0030] When the piston 531 squeezes the compression spring 532 at the bottom, the compression spring 532 at the bottom of the piston 531 will apply thrust to both ends in order to restore to its original state. Therefore, while the compression spring 532 at the bottom of the piston 531 pushes the piston 531 upward, it also pushes the extrusion block 51 downward, causing the extrusion block 51 to apply pressure to the tea cake. Therefore, when the piston 531 vibrates at a high frequency, the extrusion block 51 will apply a high-frequency impact force to the tea cake, making the pressing of the tea cake more uniform and improving the pressing efficiency.

[0031] In a further preferred embodiment of the present invention, Figure 2As shown, the compression mechanism 5 includes an extrusion block 51, a casing 52 and a vibration component 53. The top of the casing 52 is fixedly connected to the output shaft of the hydraulic press 4. The bottom of the casing 52 is provided with a slide groove 7. The extrusion block 51 is slidably connected in the slide groove 7. The vibration component 53 is arranged between the extrusion block 51 and the casing 52.

[0032] In this embodiment, since the shape of the tea leaves is irregular, the gaps between the tea leaves cannot be controlled, resulting in the inability to effectively control the density of each area when the tea leaves are piled up. As a result, when the extrusion block 51 presses the tea leaves into tea cakes, the areas with fewer gaps have a greater thickness, and therefore are compacted in advance, resulting in the areas with more gaps being relatively loose.

[0033] After the tea leaves are pressed into tea cakes, the supporting force applied to the extrusion block 51 will also increase. Therefore, as the hydraulic press 4 pushes the compression mechanism 5 to continue to move downward, the pressure on the extrusion block 51 will increase, so that the extrusion block 51 is pressed into the slide groove 7 and the vibration component 53 is triggered. The vibration component 53 applies high-frequency vibration to the extrusion block 51, so that the extrusion block 51 applies high-frequency impact force to the tea cake, so that the tea cake is pressed more evenly.

[0034] In a further preferred embodiment of the present invention, Figure 2 As shown, the vibration component 53 includes a piston 531, a compression spring 532 and a positioning unit 533. The piston 531 is slidably arranged in the slide groove 7. The top and bottom of the piston 531 are connected with compression springs 532. The compression spring 532 located at the bottom of the piston 531 is connected to the top of the extrusion block 51, and the compression spring 532 located at the top of the piston 531 is connected to the inner top wall of the slide groove 7. The outer wall of the shell 52 is connected with a positioning unit 533 for limiting the movement of the piston 531.

[0035] In this embodiment, compression springs 532 are arranged at the top and bottom of the piston 531, and the piston 531 is suspended in the slide groove 7 by utilizing the supporting force provided by the two compression springs 532 to the piston 531. When the extrusion block 51 is pressed into the slide groove 7, the compression spring 532 at the bottom of the piston 531 is squeezed to deform the compression spring 532 at the bottom of the piston 531. Therefore, the compression spring 532 at the bottom of the piston 531 pushes the piston 531 upward while compressing the other compression spring 532, thereby causing the piston 531 to be at the balance point of the two compression springs 532 and unable to vibrate. Figure 2It can be found that the positioning unit 533 is arranged near the bottom of the slide groove 7, so that when the positioning unit 533 fixes the piston 531, the piston 531 will squeeze the compression spring 532 at the bottom, so that the potential energy of the compression spring 532 at the bottom is relatively large. Therefore, when the piston 531 is released, the potential energy of the compression spring 532 at the bottom is released instantly, which will cause the piston 531 to squeeze the compression spring 532 at the top, and then the compression spring 532 at the top of the piston 531 will push the piston 531 downward to squeeze the compression spring 532 at the bottom, thereby realizing high-frequency vibration of the piston 531.

[0036] In a further preferred embodiment of the present invention, Figure 2-3 As shown, the positioning unit 533 includes a block 533a, a support spring 533b and a cone 533c. The outer wall of the housing 52 is protruded to form a cone 533c. A circular groove 8 connected to the slide groove 7 is provided in the cone 533c. The block 533a is slidably connected in the circular groove 8. A support spring 533b is provided between one side of the block 533a and the circular groove 8. The outer wall of the piston 531 is provided with a groove 9 matched with the block 533a.

[0037] In this embodiment, the piston 531 can be fixed by cooperating with the groove 9 provided on the outer wall of the piston 531. Since the block 533a is located at a position slightly below the slide groove 7, the compression spring 532 located at the bottom of the piston 531 will be compressed when the piston 531 contacts the block 533a, thereby increasing the potential energy of the compression spring 532 at the bottom of the piston 531, which will push the piston 531 upward. Therefore, a support spring 533b is provided in the circular groove 8 to provide support force to the block 533a, so that the pressure between the block 533a and the groove 9 is greater than the support force of the compression spring 532, thereby fixing the piston 531.

[0038] When the extrusion block 51 is pressed into the slide groove 7, the extrusion block 51 will continue to compress the compression spring 532, so that the potential energy of the compression spring 532 will continue to increase until the potential energy of the compression spring 532 is greater than the pressure between the block 533a and the slot 9. The compression spring 532 pushes the piston 531 to move upward and presses the block 533a into the circular groove 8 to separate the block 533a from the slot 9. At this time, the piston 531 is released and vibrates at a high frequency in the slide groove 7.

[0039] In a further preferred embodiment of the present invention, Figure 2 As shown, the bottom of the cover plate 3 is fixedly connected to a limiting column 10 , and the top of the sleeve 52 is provided with a through hole 11 for avoiding the limiting column 10 .

[0040] In this embodiment, because compression springs 532 are provided at the top and bottom of the piston 531, when a balance is reached between the two compression springs 532, the piston 531 will be fixed in the slide groove 7 and move along with the sleeve 52, which causes the piston 531 to be unable to squeeze the compression spring 532 at the bottom, making it impossible for the vibration component 53 to continue to be used. Therefore, a limiting column 10 is connected to the bottom of the cover plate 3. When the sleeve 52 is reset, the limiting column 10 enters the sleeve 52 through the through hole 11 and squeezes the piston 531, so that the piston 531 is reconnected with the positioning unit 533, thereby ensuring the efficiency of the next tea cake pressing.

[0041] In a further preferred embodiment of the present invention, Figure 1 As shown, an extrusion groove 12 is provided on the top of the pressing platform 6 , and a chamfer 13 is processed at the opening of the extrusion groove 12 .

[0042] In this embodiment, the extrusion groove 12 provided in the pressing table 6 can be used to place tea leaves, so that the compression mechanism 5 can press the tea leaves into tea cakes. However, since the relative movement between the machines must leave a gap for movement, the hydraulic press 4 will have a certain degree of deviation when pressing the compression mechanism 5, resulting in the extrusion block 51 being unable to enter the extrusion groove 12 due to contact with the top of the pressing table 6. Therefore, a chamfer 13 is provided at the opening of the extrusion groove 12 to provide guidance for the extrusion block 51, so that the compression mechanism 5 can more easily enter the extrusion groove 12 to press the tea leaves.

[0043] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
