Description

Technical Field

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

[0002] Extrusion is an important process in tea processing. Through extrusion, tea can be formed into specific shapes, such as strips, balls, cakes, etc. Different shapes of tea are not only aesthetically pleasing, but may also affect the brewing method and taste of the tea. For example, Pu'er tea is often pressed into cakes for easy storage and transportation, which is also beneficial to the later aging of the tea.

[0003] When the extrusion device is working, the tea leaves are spread on the top of the lower mold through the spreading device, and the tea leaves fall into the holes above the lower mold. Then the spreading device pushes away the excess tea leaves, and then the upper mold presses down to press the tea leaves into shape in the holes.

[0004] The patent publication number CN114536842A discloses a tea cake pressing machine including: a frame, a working platform fixed on the frame, a plurality of tea cake through holes for accommodating tea leaves on the working platform; a pressing plate, the pressing plate is located below the tea cake through holes on the working platform, and a material unloading driving component for driving the pressing plate to move up and down is provided on the frame; a feeding mechanism, the feeding mechanism includes a material unloading pipe and a material distribution plate, the material unloading pipe is fixedly connected to the frame, a limiting slide is provided between the material distribution plate and the frame, the limiting slide is clamped on both sides of the material distribution plate, the limiting slide is rotatably connected to the frame, and a rotating driving component for driving the limiting slide to rotate is provided on the frame; a clamping mechanism; and a controller. The amount of tea cakes can be accurately controlled and the processing efficiency can be improved.

[0005] The prior art has the following defects: During batch production, the standard amount of each pressed tea cake is determined by the volume of the hole above the lower mold. However, due to the different fluffiness of the tea leaves in the spreading device, the quality of the tea leaves entering the holes at different positions above the lower mold varies. The quality of tea cakes processed in batches at different times is also different, which does not meet the specifications of standardized production. In addition, tea cakes with small quality need to be reworked, broken up and re-pressed, which not only affects the processing efficiency but may also cause over-processing of the tea. Summary of the invention

[0006] In view of the problem that the specifications of tea cakes pressed out in the prior art are not uniform, a tea processing and extrusion device is proposed.

[0007] The present application provides a tea processing and extrusion device, the purpose of which is to make the specifications of tea cakes produced in batches uniform.

[0008] The technical scheme of the present invention is: a tea processing and extruding device, comprising a processing table, a material laying device and a pushing table arranged on the top of the processing table, an upper mold arranged at the bottom of the pushing table, a mounting groove group arranged on the upper surface of the processing table, a lower mold assembly and a pushing assembly arranged inside the mounting groove group, and also comprising a compacting assembly, wherein the mounting groove group comprises a top groove, a middle groove, and a bottom groove in sequence from top to bottom, the lower mold assembly specifically comprises a template arranged inside the top groove, a forming hole arranged on the surface of the template, and the pushing assembly specifically comprises a support plate arranged inside the bottom groove, and a top platform arranged on the top of the support plate; The tightening assembly specifically includes a matching plate arranged inside the middle groove, a matching hole, an air channel and an interface opened on the top of the matching plate, a bottom sleeve arranged inside the forming hole, an inner limit ring arranged at the opening below the bottom sleeve, an inner sliding sleeve arranged inside the bottom sleeve, a fixing ring arranged on the top of the inner sliding sleeve, and a partition net arranged inside the fixing ring; The top groove, middle groove and bottom groove are interconnected, and the opening areas are proportionally enlarged from top to bottom. The template extends into the middle groove and fits against the upper surface of the matching plate. The matching holes correspond to the forming holes one by one. The top platform passes through the matching plate and extends into the forming hole. When the top platform moves upward, it passes through the inner sliding sleeve and fits against the bottom wall of the partition net. The airway connects the matching hole and the interface. The other end of the interface extends horizontally to the surface of the processing table.

[0009] Furthermore, a chamfer of five millimeters is provided at the upper opening of the forming hole.

[0010] Furthermore, the thickness of the partition net is the same as the thickness of the fixing ring, and the inner diameter of the fixing ring is smaller than the inner diameter of the inner sliding sleeve.

[0011] Furthermore, the airway is divided into three parts, A, B, and C, which are branch grooves, branch connecting grooves, and aggregation grooves, respectively, wherein the branch grooves are connected to the matching holes, the branch connecting grooves are connected to all the branch grooves in a row, the aggregation grooves are connected to all the branch connecting grooves, and the aggregation grooves are also connected to the interfaces, and the cross-sectional areas of the branch grooves, branch connecting grooves, and aggregation grooves increase successively.

[0012] Furthermore, when the top platform moves downward, it moves to the bottom of the airway and stays in the matching hole.

[0013] Furthermore, the tightening assembly also includes a positioning groove formed on the surface of the inner sleeve, a mounting hole formed on the surface of the bottom sleeve, a threaded sleeve disposed inside the mounting hole, a slot formed on one end of the threaded sleeve close to the inner limiting ring, and a spring and a positioning rod disposed inside the slot; The positioning groove and the mounting hole are distributed in a circular array around the central axis of the bottom sleeve, the positions of the positioning groove and the mounting hole correspond one to one, the mounting hole passes through the bottom sleeve, the spring is located between the positioning rod and the inner wall of the slot, the positioning rod extends out of the slot and presses on the surface of the inner limit ring, and the end of the positioning rod close to the inner limit ring and the inner wall of the positioning groove are both set to hemispherical surfaces.

[0014] Furthermore, the tightening assembly also includes a sliding groove opened on the top of the top platform, an engaging groove opened at the opening above the sliding groove, a sliding rod arranged inside the sliding groove, a sliding block arranged at the bottom of the sliding rod, a limiting plate arranged inside the engaging groove, and a through hole opened on the surface of the limiting plate; The sliding groove is symmetrically arranged in the top platform, the diameter of the sliding block is larger than the diameter of the sliding rod, the through hole is concentrically arranged with the sliding groove, the diameter of the through hole is smaller than the diameter of the sliding groove, and the sliding rod passes through the through hole and is fixed to the fixing ring.

[0015] Furthermore, the sliding block is fitted with the inside of the sliding groove, and an air flow hole is provided on the outside of the sliding block.

[0016] Beneficial effects of the present invention: 1. By setting a compacting component, when the laying device fills tea leaves into the forming hole, the top platform moves to the bottom of the airway, the suction pump draws air, and negative pressure is generated under the partition. Under the adsorption of air pressure, the tea leaves in the forming hole become relatively compact, which can reduce the quality difference of tea leaves entering the forming hole at different positions and at different times, and reduce the influence of the original fluffiness of tea leaves on the filling link, which is conducive to standardized and batch production mode, reduces the error between tea cakes, and improves the quality of tea cakes. At the same time, after the pressing is completed, the suction pump blows air in the reverse direction, and the air flow flows from bottom to top in the forming hole, which can start the cleaning effect on the forming hole and the partition, and reduce the residual tea residue.

[0017] 2. By making the thickness of the partition net the same as that of the fixing ring and the inner diameter of the fixing ring smaller than the inner diameter of the inner sliding sleeve, when the top platform rises, it can contact the fixing ring and the partition net at the same time. This not only provides support for the partition net during the pressing process of the tea cake, preventing the partition net from breaking or deforming under strong pressure, but also preventing tea leaves from overflowing from the mesh holes of the partition net under strong pressure, but also allows the partition net to share the force between the partition net and the top platform, thereby protecting the partition net.

[0018] 3. By setting the positioning groove and the positioning rod, when the positioning groove is pushed upward by the top platform and the fixing ring is flush with the opening above the forming hole, the positioning rod is pushed into the positioning groove. In this way, after the top platform is retracted, the fixing ring is still flush with the upper surface of the template. Then the air flowing out from under the forming hole can better clean the partition net, and the fallen tea film will not fall into the forming hole again. At the same time, the upward airflow can also produce a uniform thrust on the formed tea cake, loosening its connection with the partition net, so that the subsequent separation effect is better.

[0019] 4. By opening air flow holes on the outside of the sliding block, air can flow on the upper and lower surfaces of the sliding block. In this way, when the lifted inner sliding sleeve, fixed ring, and partition net are reset downward, the sliding block slides downward inside the sliding groove. Since the three have a small weight, they are slowly reset under the action of air damping, which reduces the collision between parts and plays a protective role. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0023] Example 1, reference Figure 1-17 , which is the first embodiment of the present invention, provides a tea processing and extrusion device, including a processing table 1, a spreading device 2 and a pushing table 3 arranged on the top of the processing table 1, an upper mold 4 arranged at the bottom of the pushing table 3, a mounting groove group 5 opened on the upper surface of the processing table 1, a lower mold assembly 6 and a pushing assembly 7 arranged inside the mounting groove group 5, and also includes a compacting assembly 8. The mounting groove group 5 includes a top groove 51, a middle groove 52, and a bottom groove 53 from top to bottom. The lower mold assembly 6 specifically includes a template 61 arranged inside the top groove 51 and a forming hole 62 opened on the surface of the template 61. The pushing assembly 7 specifically includes a support plate 71 arranged inside the bottom groove 53 and a top platform 72 arranged on the top of the support plate 71.

[0024] The tightening component 8 specifically includes a mating plate 81 arranged inside the middle groove 52, a mating hole 82, an air duct 83 and an interface 84 opened on the top of the mating plate 81, a bottom sleeve 85 arranged inside the forming hole 62, an inner limit ring 86 arranged at the opening below the bottom sleeve 85, an inner sliding sleeve 87 arranged inside the bottom sleeve 85, a fixing ring 88 arranged at the top of the inner sliding sleeve 87, and a partition net 89 arranged on the inner side of the fixing ring 88.

[0025] Specifically, the spreading device 2 slides horizontally and reciprocatingly above the processing table 1 to push the tea leaves, which are stored inside the spreading device 2. The pushing table 3 is suspended above the processing table 1 by four pillars to provide pressure and guidance for the upper mold 4. A protruding punch head corresponding to the forming hole 62 is arranged at the bottom of the upper mold 4. The top groove 51, the middle groove 52, and the bottom groove 53 are interconnected, and the opening area is proportionally enlarged from top to bottom. The template 61 is fixed with a bolt in the top groove 51, and the template 61 extends into the middle groove 52, and It is fitted to the upper surface of the matching plate 81, and the surfaces of the fitting parts of the two are affixed with sealing cushions. The forming holes 62 are distributed in a rectangular array on the surface of the template 61. The support plate 71 is slidably installed in the bottom groove 53, and a hydraulic rod is fixedly installed at the bottom of the support plate 71. The top platform 72 is fixed to the support plate 71 by bolts. A five-millimeter chamfer is set at the opening above the forming hole 62. This prevents the tea leaves from being sheared off by the right-angled edge of the opening above the forming hole 62 when the spreading device 2 pushes the tea leaves, resulting in too much fine tea powder in the processed tea cakes.

[0026] The matching plate 81 is placed at the bottom of the middle groove 52, and the matching hole 82 corresponds to the forming hole 62 one by one. The top platform 72 passes through the matching plate 81 and extends into the forming hole 62. When the top platform 72 moves upward, it passes through the inner sliding sleeve 87 and fits the bottom wall of the partition net 89. The airway 83 connects the matching hole 82 and the interface 84. The other end of the interface 84 extends horizontally to the surface of the processing table 1. The interface 84 is externally connected to a suction air pump. An assembly groove corresponding to the bottom sleeve 85 is provided at the lower opening of the forming hole 62. The bottom sleeve 85 is installed in the assembly groove and fixed by bolts. The inner diameter of the bottom sleeve 85 is the same as the inner diameter of the forming hole 62. The inner limit ring 86 is integrally formed with the bottom sleeve 85. The inner sliding sleeve 87 is slidably installed in the bottom sleeve 85 and falls above the inner limit ring 86. The fixing ring 88 is fixed to the inner sliding sleeve 87 by bolts. The partition net 89 is welded to the fixing ring 88. When the top platform 72 moves downward, it moves to the bottom of the airway 83 and stays in the matching hole 82.

[0027] By setting the compacting component 8, when the laying device 2 fills the tea leaves into the forming hole 62, the top platform 72 moves to the bottom of the airway 83, the suction pump draws air, and negative pressure is generated under the partition 89. Under the adsorption of air pressure, the tea leaves in the forming hole 62 become relatively compact, which can reduce the quality difference of the tea leaves entering the forming hole 62 at different positions and at different times, and reduce the influence of the original fluffiness of the tea leaves on the filling process, which is conducive to standardized and batch production mode, reduces the error between tea cakes, and improves the quality of tea cakes. At the same time, after the pressing is completed, the suction pump blows air in the reverse direction, and the airflow flows from bottom to top in the forming hole 62, which can start the cleaning effect on the forming hole 62 and the partition 89 and reduce the residual tea leaves.

[0028] Specifically, the thickness of the partition net 89 is the same as the thickness of the fixing ring 88, and the inner diameter of the fixing ring 88 is smaller than the inner diameter of the inner sliding sleeve 87. In this way, when the top platform 72 rises, it can contact the fixing ring 88 and the partition net 89 at the same time. This not only provides support for the partition net 89 during the pressing process of the tea cake, preventing the partition net 89 from breaking or deforming under strong pressure, but also prevents tea leaves from overflowing from the mesh of the partition net 89 under strong pressure, and can also enable the partition net 89 to share the force between the partition net 89 and the top platform 72, thereby protecting the partition net 89.

[0029] Specifically, the airway 83 is divided into three parts, A, B, and C, which are branch grooves, branch connecting grooves, and aggregation grooves, respectively. The branch grooves are connected to the matching holes 82, the branch connecting grooves are connected to all the branch grooves in a row, the aggregation grooves are connected to all the branch connecting grooves, and the aggregation grooves are also connected to the interface 84. The cross-sectional areas of the branch grooves, branch connecting grooves, and aggregation grooves increase successively, and the cross-section here is a surface perpendicular to its own central axis.

[0030] By setting the branch grooves, branch connection grooves and converging grooves of the airway 83 to different sizes, the airflow can be made smoother and more stable when flowing inside.

[0031] Example 2, reference Figure 10-18 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the tightening component 8 also includes a positioning groove 810 opened on the surface of the inner sliding sleeve 87, a mounting hole 811 opened on the surface of the bottom sleeve 85, a threaded sleeve 812 arranged inside the mounting hole 811, a slot 813 opened at one end of the threaded sleeve 812 close to the inner limiting ring 86, a spring 814 and a positioning rod 815 arranged inside the slot 813; the tightening component 8 also includes a sliding groove 816 opened on the top of the top platform 72, an engaging groove 817 opened at the opening above the sliding groove 816, a sliding rod 818 arranged inside the sliding groove 816, a sliding block 819 arranged at the bottom of the sliding rod 818, a limiting plate 820 arranged inside the engaging groove 817, and a through hole 821 opened on the surface of the limiting plate 820.

[0032] Specifically, the positioning groove 810 and the mounting hole 811 are distributed in a circular array around the central axis of the bottom sleeve 85, and the positions of the positioning groove 810 and the mounting hole 811 correspond one to one. The threaded sleeve 812 is threadedly installed in the positioning groove 810, and the mounting hole 811 passes through the bottom sleeve 85. The spring 814 is located between the positioning rod 815 and the inner wall of the slot 813, and the two ends are respectively welded to the two. The positioning rod 815 extends out of the slot 813 and presses on the surface of the inner limit ring 86. When the inner limit ring 86 moves, the positioning rod 815 can be pushed into the positioning groove 810. The end of the positioning rod 815 close to the inner limit ring 86 and the inner wall of the positioning groove 810 are both set to hemispherical surfaces.

[0033] The sliding groove 816 is symmetrically arranged in the top platform 72, the diameter of the sliding block 819 is larger than the diameter of the sliding rod 818, the sliding rod 818 and the sliding block 819 are fixedly connected, the sliding rod 818 is slidably inserted in the sliding groove 816, the through hole 821 is concentrically arranged with the sliding groove 816, the diameter of the through hole 821 is smaller than the diameter of the sliding groove 816, the sliding rod 818 passes through the through hole 821 and is fixed to the fixing ring 88, the limiting plate 820 is embedded in the fitting groove 817 and fixed by bolts.

[0034] By setting the positioning groove 810 and the positioning rod 815, when the positioning groove 810 is pushed upward by the top platform 72 and the fixing ring 88 is flush with the upper opening of the forming hole 62, the positioning rod 815 is pushed into the positioning groove 810. In this way, after the top platform 72 retreats, the fixing ring 88 is still flush with the upper surface of the template 61. Subsequently, the air flowing out from under the forming hole 62 can better clean the partition net 89, and the fallen tea film will not fall into the forming hole 62 again. At the same time, the upward airflow can also generate a uniform thrust on the formed tea cake, loosening its connection with the partition net 89, so that the subsequent separation effect is better.

[0035] Specifically, the sliding block 819 fits inside the sliding groove 816, and the friction between the two is small, so they can slide freely. The outer side of the sliding block 819 is provided with air flow holes, so that air can flow on the upper and lower surfaces of the sliding block 819. In this way, when the lifted inner sliding sleeve 87, fixed ring 88, and partition net 89 are reset downward, the sliding block 819 slides downward inside the sliding groove 816. Since the three have a small weight, they are slowly reset under the action of air damping, which reduces the collision between parts and plays a protective role.

[0036] Above all the bolts used in the areas where tea leaves can directly reach the above, sealing caps are used to seal the corresponding screw holes.

[0037] Based on Examples 1-2, the working principle of a tea processing and extrusion device of the present invention is as follows: During installation, insert the sliding rod 818 into the sliding groove 816, keep the sliding block 819 downward during this process, then install the limiting plate 820 into the fitting groove 817 and fix it with bolts. The top of the sliding rod 818 passes through the sliding groove 816 through the through hole 821, and then use the hydraulic rod to push the top platform 72 to the highest point it can reach; place the matching plate 81 into the middle groove 52, and the matching hole 82 corresponds to the top platform 72 one by one; first fix the fixing ring 88 on one end of the inner limiting ring 86, and then slide the inner limiting ring 86 from the top into the bottom sleeve 85, keep the fixing ring 88 on the top during this process, and then screw the threaded sleeve 812 into the installation hole 81 1, during this process, as the threaded sleeve 812 enters, the positioning rod 815 is continuously pushed into the slot 813 by the inner limit ring 86, and finally the matching hole 82 is inserted into the forming hole 62 from below and fixed with bolts; the template 61 is installed in the top groove 51, the template 61 partially extends into the middle groove 52, and fits with the upper surface of the matching plate 81, and the top platform 72 is inserted into the forming hole 62. As the template 61 moves downward, the top platform 72 lifts the positioning groove 810 and the fixing ring 88. At this time, the fixing ring 88 is flush with the upper surface of the template 61, and the sliding rod 818 is pressed under the fixing ring 88. The sliding rod 818 and the fixing ring 88 are fixed with screws.

[0038] When in use, the hydraulic rod drives the top platform 72 to move to the bottom of the air duct 83 through the support plate 71, and then the spreading device 2 moves with the tea leaves to the top of the lower mold assembly 6, and the tea leaves in the spreading device 2 fall into the forming hole 62. At this time, the suction air pump is started, and a suction force is formed in the matching hole 82 and the forming hole 62 along the interface 84 and the air duct 83. The air in the forming hole 62 flows from top to bottom. In this way, under the action of air pressure, the tea leaves in the forming hole 62 become increasingly compact. After a period of time, the forming hole 62 is filled, and the spreading device 2 leaves the lower mold assembly 6 with the tea leaves that have not entered the forming hole 62.

[0039] The upper mold 4 starts to move downward, and when the punch head at the bottom of the upper mold 4 is about to enter the forming hole 62, it pauses for two seconds. During these two seconds, the hydraulic rod pushes the top platform 72 upward through the support plate 71, and the top platform 72 moves upward to the bottom of the fixed ring 88 and then stops moving. Then the upper mold 4 continues to press down to press the tea leaves into tea cakes.

[0040] After being stationary for a period of time, the upper mold 4 and the top platform 72 move upward synchronously, the top platform 72 is lifted under the fixing ring 88, and the fixing ring 88 is pushed upward, and the fixing ring 88 drives the inner sliding sleeve 87 to slide in the bottom sleeve 85, and drives the sliding rod 818 and the sliding block 819 to slide in the sliding groove 816, until the fixing ring 88 is flush with the upper surface of the template 61 and stops moving, and the upper mold 4 continues to move upward to reset, at this time, the positioning groove 810 is connected with the mounting hole 811, and the positioning rod 815 is pushed into the bottom sleeve 85 under the action of the spring 814. In the positioning groove 810, the position of the inner limit ring 86 is locked, and the top platform 72 then moves downward until the top platform 72 moves to the bottom of the airway 83 and pauses for a while. At this time, the sliding block 819 contacts the limit plate 820, and the air pump is sucked to start blowing. The air flow enters the matching hole 82 along the interface 84 and the airway 83, and then flows upward from the bottom of the forming hole 62, generating a uniform thrust on the tea cake, loosening the connection between it and the partition net 89. At the same time, the air flow also blows away the scattered tea leaves, and the pressing work is completed at one time.

[0041] The spreading device 2 moves again to put in the tea leaves, and moves in the direction of the lower mold assembly 6 to push the formed tea cake away. The top platform 72 continues to move down for a distance. Previously, the sliding rod 818 has been pulled to the limit. At this time, as the top platform 72 moves downward, the fixing ring 88 is pulled downward by the sliding rod 818, and the fixing ring 88 drives the inner sliding sleeve 87 to move downward. The positioning rod 815 is pushed back to the threaded sleeve 812, and the inner limit ring 86 causes its limit to start moving downward. The inner sliding sleeve 87, the fixing ring 88, the sliding rod 818, and the sliding block 819 move synchronously. When the sliding block 819 moves downward, the air inside the sliding groove 816 flows upward from the air flow hole, and under the action of air damping, it plays a role of slowing down the descent. When the inner sliding sleeve 87 is reset, the tea leaves in the spreading device 2 fall into the forming hole 62 again, and the suction air pump sucks again to start a new round of pressing work.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
