Description

Technical Field

[0001] The invention relates to the technical field of tea processing, in particular to a hot air tea-fixing and tea-stripping machine with a windproof fence. Background Art

[0002] In the existing tea processing technology, withering and striping are two steps. The withered leaves are conveyed to the striping machine through a conveyor belt for striping. The main purpose of withering is to destroy and passivate the oxidase activity in the fresh leaves through high temperature, inhibit the enzymatic oxidation of tea polyphenols in the fresh leaves, and prevent discoloration during the drying process. At the same time, it emits a green smell and promotes the formation of a good aroma. The function of the striping machine is to repeatedly move the striping machine through mechanical transmission to make fresh tea leaves into strips.

[0003] In the existing tea withering and strip-straightening machines, the withering machine is placed above the strip-straightening machine, and there is a gap of 2 to 3 cm in the feeding space. The hot air blown out by the withering machine can easily escape from this gap, resulting in reduced thermal efficiency of the withering machine. In addition, the high-frequency movement of the strip-straightening trough plate can easily cause the tea leaves in the trough to escape and spill from this gap, causing waste.

[0004] At the same time, the advantage of the all-in-one machine is that it occupies a small area, and the loading, killing, strip sorting and unloading are integrated. There are two ways to load the material, one is Fig.12 As shown, a protective cover 100 is provided at the feeding end of the stripping machine, and a feeding machine (not shown) spreads the tea leaves in advance and then drops them into the protective cover 100; another method is as shown in FIG. Figure 1 As shown, the feeder drops the tea leaves into the leaking tray 1, which then slides into the feeding end of the strip sorting machine from the leaking tray 1. Both feeding methods rely on the paving effect of the feeder. Due to the high-frequency movement of the slot plate of the strip sorting machine, the fixedly installed leaking tray also moves synchronously, so that the tea leaves entering the leaking tray tend to accumulate at the edge due to the high-frequency movement, resulting in insufficient uniformity in the amount of tea leaves received by each slot on the strip sorting plate. Too much tea leaves in a single slot affects the quality of strip sorting, while reducing the amount of tea leaves to be sorted in a single slot will reduce the efficiency of strip sorting, making it difficult for users to strike a balance between strip sorting quality and strip sorting efficiency. Summary of the invention

[0005] In view of the deficiencies of the prior art raised in the above background technology, the present invention provides a hot air withering and tea stripping machine with a windshield fence, which has the advantages of effectively blocking the escape of hot air and tea leaves, occupying a small area, and greatly improving the stripping efficiency, thereby solving the problems raised in the above background technology.

[0006] The present invention provides the following technical solution: a hot air fixing and strip sorting machine with a windshield fence, comprising a leakage tray, a fixing machine, a strip sorting machine and a frame, the upper end of the frame is provided with a fixedly sleeved fixing machine, the fixing machine is provided with an air inlet, two sliding grooves are provided at the bottom of the frame, the sliding grooves are provided with movable supporting bearings and limit bearings, a strip sorting machine is provided above the supporting bearings and between the fixing machine, a leakage tray for feeding is provided on one end face of the strip sorting machine, a leakage hopper is fixedly installed on the other end of the strip sorting machine by screws, windshield fences fixedly installed by screws are provided on both sides of the strip sorting machine, and the windshield fences are used to control the hot air discharged from the fixing machine to the upper area of ​​the strip sorting machine.

[0007] Preferably, the top edge height of the windshield fence is higher than the bottom edge height of the withering machine.

[0008] Preferably, the drain tray and the strip sorting machine are separately arranged, and a transmission gear shaft I and a transmission gear shaft II are provided below the drain tray. A rack is provided below the feed end of the strip sorting machine and is meshed with the gear at one end of the transmission gear shaft I, the other end of the transmission gear shaft I is meshed with one end of the transmission gear shaft II, and the other end of the transmission gear shaft II is meshed with the rack at the bottom of the drain tray.

[0009] Preferably, the two ends of the transmission gear shaft I are completely identical gears, and the two ends of the transmission gear shaft II are gears of different sizes. The small gear at one end of the transmission gear shaft II is completely identical to the gear at one end of the transmission gear shaft I, and the large gear at the other end of the transmission gear shaft II and the gear at one end of the transmission gear shaft I have a meshing transmission ratio of no less than 4:1.

[0010] Preferably, the strip sorting machine is composed of a reciprocating mechanism driving a strip sorting groove to move back and forth, a plurality of the strip sorting grooves are arranged in a linear array to form a strip sorting plate, an inner groove wall is provided between two adjacent strip sorting grooves, and the height of the inner groove wall of the front section of the strip sorting groove is halved.

[0011] Preferably, the cross section of the middle section of the strip sorting groove has a diameter that gradually decreases along the length outlet direction, so that the side surface of the inner groove wall forms an inclined surface.

[0012] Preferably, a partition is provided in the drain pan, a push column is provided at the feed end of the strip sorting machine, the cross section of the push column is a trapezoidal protrusion, a strip-shaped push rod is provided under the partition, and when the strip sorting machine and the drain pan are arranged in alignment, the push column and the push rod are arranged synchronously and correspondingly.

[0013] Preferably, a partition is provided in the drain pan, and a push column is provided at the feed end of the strip sorting machine. The push column is a rectangular protruding block, and an arc-shaped groove is opened in the upper middle part of the push column. A strip-shaped push rod is provided under the partition. When the strip sorting machine and the drain pan are arranged in alignment, the arc-shaped groove of the push column and the push rod are arranged synchronously and correspondingly.

[0014] Preferably, when the tappet reaches the inner bottom of the arc-shaped groove of the tappet, the surface above the partition is flush with the inner bottom surface of the drain disc.

[0015] The present invention has the following beneficial effects:

[0016] 1. The present invention adds windbreak fences on the left and right edges of the strip-sorting board, and at the same time sinks the air outlet surface of the withering machine within the height of the windbreak fence, so that the hot air moves in the area above the strip-sorting board due to the high-frequency left and right movement of the strip-sorting board, and does not exhaust and sink to the two sides of the strip-sorting board, thereby effectively improving the thermal efficiency; at the same time, because the hot air is blocked from being discharged and sinking, the problem of heat dissipation protection of the bearings supporting the strip-sorting board is effectively solved, and the heat dissipation fan originally used to support the bearings is removed, further reducing energy consumption and saving space.

[0017] 2. The added windbreak fence can also serve as a material barrier when the slat sorting board moves back and forth at high frequency, effectively preventing the tea leaves in the slat sorting groove from escaping and spilling; in addition, the windbreak fence can moderately increase the edge bending strength of the slat sorting board and improve its aesthetics.

[0018] 3. The present invention sets the leakage tray and the strip-sorting plate separately, and controls the relative movement frequency of the strip-sorting plate and the leakage tray by the transmission gear shaft I and the transmission gear shaft II with the rated transmission ratio, so that the tea leaves in the leakage tray are evenly spread and then enter the corresponding strip-sorting groove, so that each strip-sorting groove obtains a relatively uniform amount of tea leaves.

[0019] 4. By setting the push rod and the push column, the partition is lifted to discharge the material only when the leakage plate and the strip sorting plate are aligned, thereby effectively ensuring that the leakage plate and the strip sorting plate move at the same frequency but different amplitudes and discharge the material evenly into the corresponding strip sorting groove.

[0020] 5. By lowering the height of the front part of the groove wall of each strip sorting groove, the tea leaves just entering the strip sorting groove can be spread out again under the high-frequency reciprocating motion of the strip sorting plate, further ensuring that the tea leaves in each strip sorting groove are evenly distributed.

[0021] 6. By designing the inner wall width of the middle section of the strip sorting trough to be gradually reduced, the inner wall of this section is an inclined surface. When the strip sorting plate moves back and forth left and right at a high frequency, the tea leaves passing through this section hit the inclined surface and fall back, and the landing point moves backward, thereby extending the time for the tea leaves to pass through this section, thereby compensating for the loss of strip sorting time when the tea leaves are evenly spread in the front section of the strip sorting trough, and saving the equipment floor space under the premise of ensuring the comprehensive strip sorting effect.

DETAILED DESCRIPTION

[0035] 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.

[0036] Explanation of the terms "left and right" and "front and back" in this application. Figure 1For example, the length direction of the rack 4 is the "front-rear" direction, and the width direction of the rack 4 is the "left-right" direction. The "front-rear" direction and the "left-right" direction are perpendicular to each other. Unless otherwise specified, the "front-rear" and "left-right" directions mentioned in this application are based on this.

[0037] See also Figure 1-Figure 3 A hot air tea-fixing and tea-stripping machine with a windproof fence is composed of a leaking plate 1, a tea-fixing machine 2, a tea-stripping machine 3 and a frame 4. The middle part of the frame 4 is provided with a tea-stripping machine 3 that can reciprocate left and right relative to the frame 4. The middle part of the frame 4 and above the feeding end of the tea-stripping machine 3 is provided with a fixedly installed tea-fixing machine 2. The top of the tea-fixing machine 2 is provided with an air inlet 6, and the tea-fixing machine 2 fixes the tea leaves entering the tea-stripping machine 3. The attached drawings of the present invention only illustrate the installation position of the tea-fixing machine, and its specific structural composition is not fully shown. The tea-fixing machine 2 in the figure is actually a hot air hood part. The hot air enters from the air inlet 6, and is evenly distributed in the hot air hood and blows to the top of the tea-stripping machine 3; the power mechanism for the tea-stripping machine 3 to reciprocate left and right relative to the frame 4 is traditionally set as a disc eccentric hinged crankshaft, or other mechanisms for driving reciprocating movement. The present invention does not make specific requirements and is not shown in the drawings.

[0038] A drain pan 1 is provided at the end of the frame 4 and at the feeding end of the tea-fixing machine 2, and a drain hopper 8 is provided at the other end of the frame 4. Tea leaves to be processed are added through the drain pan 1. After the tea leaves enter the tea-fixing machine 2 and are finished fixing, they are discharged into the tea-strip sorting machine 3 for sorting. After the tea leaves are sorted, they are discharged and collected through the drain hopper 8. The tea-fixing machine 2 and the tea-strip sorting machine 3 are installed in one piece, and tea leaves can be fixed and sorted at the same time, so the floor space of the tea-fixing and tea-strip sorting machine in the factory can be reduced, the process conversion process can be saved, and the efficiency of tea-fixing and tea-strip sorting can be improved.

[0039] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 The tea stripping machine 3 is actually composed of a reciprocating mechanism driving the tea stripping groove 15 to move back and forth. The tea leaves that have completed the withering repeatedly hit the inner wall of the tea stripping groove 15 to complete the tea stripping, and finally discharged from the hopper 8. A plurality of tea stripping grooves 15 are arranged in a linear array to form a tea stripping board, and windbreak fences 9 are provided on the left and right edges of the tea stripping board. The windbreak fence 9 is a stainless steel plate with a smooth surface, which is fixed to the side of the tea stripping board by bolts. Figure 2 and Figure 3 The setting height of the windshield fence 9 is higher than the height of the lower edge of the hot air hood of the fixing machine 2, so that the hot air discharged from the hot air hood is blocked by the windshield fence 9.

[0040] See also Figure 6 and Figure 8The support mechanism for the reciprocating movement of the strip-sorting plate is composed of a support bearing 71 and a limit bearing 72. The support bearing 71 and the limit bearing 72 are installed on the sliding groove 7. The sliding groove 7 is fixedly installed on the frame 4 horizontally. The bottom of the strip-sorting plate is provided with a support bearing 71 for bearing weight, and the support bearing 71 is rollingly connected in the sliding groove 7. Limit bearings 72 are provided on both sides of the top of the sliding groove 7. The limit bearings 72 are used to limit the front and rear directions of the strip-sorting plate, so that the strip-sorting plate can only reciprocate along the groove direction of the sliding groove 7. There are four groups of support mechanisms, which are arranged in a rectangular array at the bottom of the strip-sorting plate. For the arrangement of the support mechanism and the sliding groove 7, please refer to Figure 6 shown.

[0041] In actual production, after the fixing machine 2 is installed above the strip-stripping machine 3, since the strip-stripping board needs to move relative to the frame 4, there is a longitudinal upward gap between the top of the strip-stripping board and the edge of the frame 4, and the height is about 2 to 3 cm. During the fixing process of the fixing machine 2, hot air will be discharged along the strip-stripping groove 15. Since the left-right movement frequency of the strip-stripping board is too high during operation (about 300 times / minute reciprocating movement), the inventor found that there is a ventilation phenomenon in the gap. In order to improve the thermal efficiency, the fixing machine 2 is sunken and installed on the inner walls on both sides of the frame 4, and the height of the windshield fence 9 is set to about 5 cm and covers the gap. Therefore, by fixing the windshield fence 9 on the strip-stripping board, when the strip-stripping board moves back and forth at a high frequency, the windshield fence 9 plays the role of a fan plate, and the discharged hot air is gathered in the upper area of ​​the strip-stripping board, and the air is not discharged to the sides and sinks, effectively preventing the hot air from escaping, thereby improving the utilization rate of the hot air and improving the thermal efficiency. After this setting, by detecting the hot air speed near the withering machine 2 and the top of the stripping board, it was about 0.6-0.8m / s before setting, and about 1.3m / s after setting. It is roughly estimated that it has increased by 20%-30%, effectively improving the utilization rate of hot air.

[0042] At the same time, due to the existence of the gap before the improvement, the hot air sinks after being discharged through the gap, affecting the bearings of the supporting mechanism below the area. Floor fans need to be installed at the positions of these bearings in the factory to exhaust and dissipate heat to protect the normal use of the bearings. After the wind shield fence 9 is added, since there is no hot air sinking, the bearings are not affected by heating, so the floor fans and other related heat dissipation auxiliary appliances can be removed, effectively saving energy consumption.

[0043] The additional windshield fence 9 can play a material blocking role, which can prevent the tea leaves in the high-frequency moving strip trough 15 from falling through the gap. In addition, because the strip board moves back and forth at high frequency, the weight of the strip board should not be too heavy, otherwise it will increase the energy consumption of the strip machine 3; the weight should not be too light, otherwise the structural bending strength of the strip machine under high-frequency reciprocating movement cannot be guaranteed. The additional windshield fence 9 can improve the edge bending strength of the strip board. And the stainless steel windshield fence 9 can improve the aesthetics.

[0044] See also Figure 5 As shown, a transmission gear shaft Ⅰ11 and a transmission gear shaft Ⅱ10 are provided below the leakage tray 1, and the two ends of the transmission gear shaft Ⅰ11 are completely identical gears, and the two ends of the transmission gear shaft Ⅱ10 are gears of different sizes, wherein the small gear 102 at one end of the transmission gear shaft Ⅱ10 is completely identical to the gear at one end of the transmission gear shaft Ⅰ11, and the large gear 101 at the other end of the transmission gear shaft Ⅱ10 is meshed with the gear at one end of the transmission gear shaft Ⅰ11, and the transmission ratio is not less than 4:1. The transmission ratio can be dynamically adjusted and replaced according to the amount of material of the leakage tray 1 and the reciprocating frequency of the strip-sorting plate. The transmission gear shaft Ⅰ11 and the transmission gear shaft Ⅱ10 are both mounted on the bracket 4 through a rotating support.

[0045] A rack is provided below the feeding end of the strip-sorting plate and meshes with the gear at one end of the transmission gear shaft Ⅰ11. The other end of the transmission gear shaft Ⅰ11 meshes with the large gear 101 at one end of the transmission gear shaft Ⅱ10. The small gear 102 at the other end of the transmission gear shaft Ⅱ10 meshes with the rack at the bottom of the drain pan 1. Thus, the strip-sorting plate reciprocates, and the drain pan 1 is driven to reciprocate at the same frequency but different amplitudes through the transmission of the gear-gear shaft (that is, the reciprocating movement of the strip-sorting plate and the drain pan 1 is at the same frequency but different amplitudes, and the single-frequency movement distance of the strip-sorting plate is greater than the single-frequency movement distance of the drain pan). By separating the drain pan 1 and the strip-sorting plate and periodically moving synchronously according to the transmission ratio, the movement frequency of the drain pan 1 is reduced, so that the reciprocating movement of the drain pan 1 slows down, preventing excessive accumulation of tea leaves on both sides, and being able to complete uniform distribution in the drain pan 1 in advance, and then evenly slide to each corresponding strip-sorting groove 15 on the strip-sorting plate, so that each strip-sorting groove 15 obtains a relatively uniform amount of tea leaves.

[0046] The moving range of the drain pan 1 is smaller than that of the strip sorting plate, so that the tea leaves will not fall out of the equipment near the strip sorting groove 15 in the middle area of ​​the strip sorting plate in the discharge range of the drain pan 1.

[0047] In order to ensure that each strip sorting groove 15 can obtain a nearly uniform amount of tea leaves, the height of the inner groove wall 14 of the front section of the strip sorting groove 15 is halved so that the tea leaves can be spread flat into each strip sorting groove 15 when the strip sorting plate moves back and forth, thereby improving the space utilization rate of each strip sorting groove 15 in a single sorting process.

[0048] The cross section of the middle section of the strip sorting groove 15 is gradually reduced in diameter along the length outlet direction. The specific contour shape is obtained by placing the inclined truncated cone horizontally, taking the smaller end face circle diameter as the section, and cutting along the horizontal generatrix, such as Figure 6 and Fig. 9 As shown. Due to the inclination of the inner groove wall 14, when the strip-sorting plate moves left and right, the tea leaves will hit the inner groove wall 14 and fall back, thereby increasing the time for the tea leaves to be sorted in this section, compensating for the problem that the time for the tea leaves to be sorted in the strip-sorting groove 15 is shortened due to the setting of the half-height section of the inner groove wall 14. In this way, the equipment footprint can be controlled while ensuring the strip-sorting effect.

[0049] Embodiment 1

[0050] See also Figure 5 , Figure 7 , a partition 5 is provided in the leakage plate 1, Figure 7 As shown, a push column 12 is provided at the feeding end of the strip sorting machine 3, and the cross-section of the push column 12 is a trapezoidal protruding block. A strip-shaped push rod 13 is provided under the partition 5. When the strip sorting plate moves left and right, since the push column 12 reciprocates left and right with the strip sorting machine 3, the push rod 13 will move back and forth along with the bottom end of the trapezoid to the top end and then to the bottom end, supporting the push rod 13 and then falling down, achieving a lifting effect. When the push rod 13 drives the partition 5 to lift upward, the tea leaves in the leakage tray 1 will slide from under the partition 5 into each strip sorting groove 15.

[0051] See also Figure 5 Regarding the transmission gear pair arranged below the drain pan 1, a single gear can be additionally provided at the end of the large gear 101 and the transmission gear shaft Ⅰ11 to mesh, so that the transmission gear shaft Ⅰ11 and the transmission gear shaft Ⅱ10 rotate in the same direction, thereby making the drain pan 1 and the strip-sorting plate move in the same direction, frequency and amplitude. This can extend the lifting time of the partition 5.

[0052] The method of using this embodiment is as follows:

[0053] First, start the strip sorting machine 3 and make it move back and forth left and right. The rack of the strip sorting machine 3 drives the transmission gear shaft Ⅰ11 to rotate, and the transmission gear shaft Ⅰ11 transmits power to the transmission gear shaft Ⅱ10. The transmission gear shaft Ⅱ10 meshes with the rack under the leakage plate 1, driving the leakage plate 1 to move back and forth left and right at the same time. The tea leaves in the leakage plate 1 will be spread in the leakage plate 1 as the leakage plate 1 moves back and forth left and right. The push rod 12 at one end of the strip sorting machine 3 will support the push rod 13 under the partition 5 in the leakage plate 1, and the tea leaves will fall into the strip sorting machine 3 from the gap under the partition 5 for strip sorting.

[0054] The withering machine 2 starts working at the same time, and air enters the withering machine 2 from the air inlet 6. At this time, the withering machine 2 starts to blow hot air into the tea stripping machine 3, heating the tea leaves being sorted in the tea stripping machine 3 with hot air, so that the oxidase in the tea leaves loses its activity under the high temperature environment.

[0055] The tea leaves are then sorted by the teacup 12 and the tea leaves are then sorted by the teacup 22. The tea leaves are sorted by the teacup 12 and the tea leaves are then sorted by the teacup 23. The tea leaves are sorted by the teacup 12 and the tea leaves are then sorted by the teacup 23.

[0056] Embodiment 2

[0057] When the partition 5 falls, the tea leaves will be squeezed. Fig.11 As shown, a partition 5 that can no longer squeeze the tea leaves, Fig.11 The figure shows a partition 5 that can be embedded in the drain pan, which is different from the one in the first embodiment. Figure 5 and Figure 6 The difference between the partition 5 shown is that Fig.11 The partition 5 shown is relative to Figure 5 and Figure 6 The partition 5 shown is shorter, Fig.11 The push rod 12 shown is a rectangular protrusion, but an arc-shaped groove is provided in the middle of the upper part for controlling the up and down movement of the push rod 13. When the push rod 13 reaches the lowermost end of the arc-shaped groove of the push rod 12, the surface above the partition 5 will be flush with the inner bottom surface of the drain tray 1, and the tea leaves will slide from the top of the partition 5 into the strip sorting groove 15. When the push rod 13 reaches the highest point of the push rod 12, the partition 5 will gradually rise to block the tea leaves in the drain tray 1 in the drain tray 1. The drain tray 1 itself will also move with the left and right reciprocating movement of the strip sorting plate, so that the tea leaves in the drain tray 1 can achieve a flat effect.

[0058] See also Figure 5 Regarding the transmission gear pair arranged below the drain pan 1, a single gear can be additionally provided at the end of the large gear 101 and the transmission gear shaft Ⅰ11 to mesh, so that the transmission gear shaft Ⅰ11 and the transmission gear shaft Ⅱ10 rotate in the same direction, thereby making the drain pan 1 and the strip-sorting plate move in the same direction, frequency and amplitude. This can extend the downward movement time of the partition 5.

[0059] The method of using this embodiment is as follows:

[0060] First, start the strip sorting machine 3 and make it move back and forth left and right. The rack of the strip sorting machine 3 drives the transmission gear shaft Ⅰ11 to rotate, and the transmission gear shaft Ⅰ11 transmits power to the transmission gear shaft Ⅱ10. The transmission gear shaft Ⅱ10 meshes with the rack under the leakage plate 1, driving the leakage plate 1 to move back and forth left and right at the same time. The tea leaves in the leakage plate 1 will be spread in the leakage plate 1 as the leakage plate 1 moves back and forth left and right. The push column 12 at one end of the strip sorting machine 3 will move the partition 5 in the leakage plate 1 downward, and the tea leaves will enter the strip sorting machine 3 from the upper surface of the partition 5 for strip sorting.

[0061] The withering machine 2 starts working at the same time, and air enters the withering machine 2 from the air inlet 6. At this time, the withering machine 2 starts to blow hot air into the tea stripping machine 3, heating the tea leaves being sorted in the tea stripping machine 3 with hot air, so that the oxidase in the tea leaves loses its activity under the high temperature environment.

[0062] The tea leaves are then sorted by the teacup 12 and the tea leaves are then sorted by the teacup 20. The tea leaves are sorted by the teacup 20 and the tea leaves are then sorted by the teacup 20. The tea leaves are sorted by the teacup 20 and the tea leaves are then sorted by the teacup 20.
