Description

Technical Field

[0001] This invention relates to the field of tea processing technology, and more specifically to an automatic feeding device for tea processing. Background Technology

[0002] In tea processing, the tea leaves need to be transported from one step to the next between steps such as fixing, rolling, and drying. This process is usually accomplished using a belt feeder. Existing belt feeders have several baffles evenly arranged along the conveyor belt in the conveying direction, and hoppers are located at the bottom of the belt. Tea leaves are fed into the hoppers. When the conveyor belt rotates, the baffles pass over the bottom of the hoppers, pushing the tea leaves at the bottom of the hoppers to move diagonally upwards along the conveyor belt, thus achieving automatic feeding of the tea leaves.

[0003] However, the above-mentioned feeding method has the following shortcomings in actual use: First, the partition can only push a portion of the tea leaves at the bottom of the hopper at a time, while the rest of the tea leaves are blocked inside the hopper by the partition. Under the pushing action of the partition, the tea leaves will be squeezed and rubbed together and with the partition, resulting in tea leaf damage and affecting the appearance quality and yield of the tea. Second, since the space between the partitions is fixed, the amount of tea leaves carried by the partition when it passes through the hopper may be too much or too little, and the tea leaves are unevenly distributed between adjacent partitions, affecting the processing effect of subsequent processes. For this reason, existing feeding machines usually have a material equalization plate installed above the conveyor belt. The rotation direction of the material equalization plate is opposite to the direction of tea leaf movement, thereby pushing the excess tea leaves between adjacent partitions downward to achieve material equalization. However, the tea leaves that are pushed down accumulate at the bottom of the conveyor belt and roll downward with the operation of the conveyor belt. Long-term operation will cause the tea leaves that are pushed down to accumulate more and more at the bottom of the conveyor belt. During the accumulation process, the tea leaves are squeezed and rubbed, which further leads to tea leaf damage, and the accumulated tea leaves will also affect the normal operation of the feeding machine.

[0004] Therefore, there is an urgent need for an automatic feeding device for tea processing that can reduce tea leaf compression and breakage during the feeding process while achieving uniform feeding. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing an automatic feeding device for tea processing, thereby reducing tea leaf compression and breakage during the feeding process and achieving uniform tea leaf distribution.

[0006] The objective of this invention can be achieved through the following technical solutions: An automatic feeding device for tea processing includes a support frame and a mounting bracket installed on the support frame. The device further includes: The conveyor belt is rotatably mounted on the mounting frame, and several partitions are evenly distributed on the conveyor belt. The drive unit is mounted on the mounting frame and is connected to the conveyor belt drive. Protective plates are installed on the mounting frame and located on both sides of the conveyor belt; The feeding hopper is installed at an angle inside the protective plate and above the conveyor belt. A tilting plate is rotatably installed at the bottom of the inclined inner cavity of the feeding hopper. The slide plate is slidably installed at the bottom of the hopper. The slide plate has a discharge hole, which corresponds to the tilting plate. When the slide plate slides to the point where the discharge hole coincides with the tilting plate, the tilting plate flips down and opens. An elastic telescopic plate is installed between the slide plate and the hopper. The material distribution assembly includes a hinge plate and a material distribution plate. The hinge plate is rotatably mounted on the end of the slide plate. The material distribution plate is connected to the hinge plate and abuts against the conveyor belt. The material distribution plate is equipped with a material distribution rake for processing excess tea leaves.

[0007] As a further embodiment of the present invention: hook plates are symmetrically provided on the material distribution plate, and outer edge strips are provided on both outer edges of the conveyor belt. An elastic element is connected between the back of the hinge plate and the upper hopper. The hook plates and the outer edge strips elastically abut against each other. The partition plate is located on the path of the outer edge strip.

[0008] As a further aspect of the present invention: the uniform material plate is slidably installed inside the hinge plate, and an elastic element is connected between the hinge plate and the uniform material plate.

[0009] As a further aspect of the present invention: the material leveling plate has a flow channel, which is connected to the inner cavity of the hinge plate, and the other end of the flow channel is located inside the material leveling rake. A second spring is elastically rotatably installed on the material leveling rake at the position corresponding to the end of the flow channel. The second spring always tends to rotate inward toward the flow channel. Several first springs are elastically rotatably installed on the hinge plate. The first springs always tend to rotate outward toward the hinge plate. When the material leveling plate moves outward toward the hinge plate, air pushes several first springs into the inner cavity of the hinge plate. When the material leveling plate moves inward toward the hinge plate, air enters the flow channel and pushes the second springs to flip and spray out.

[0010] As a further aspect of the present invention: an air chamber is provided inside the slide plate, the air chamber is close to the material equalization component, a connecting hole is provided at the bottom of the flip plate, a connecting cavity is provided inside, a number of air jet holes are provided at the top, and an air pump is installed on the side of the protective plate. When the slide plate moves obliquely upward, the air chamber first connects to the output end of the air pump, and then connects to the connecting hole. When the air chamber passes the connecting hole, the air chamber is disconnected from the air pump.

[0011] As a further aspect of the present invention: a collection chamber is provided inside the slide plate, the collection chamber and the air chamber are opposite each other across the discharge hole, and an inclined filter plate is provided on the side of the collection chamber near the discharge hole.

[0012] As a further aspect of the present invention: the path of the flipping plate flipping downwards coincides with the inclined end of the filter plate.

[0013] As a further aspect of the present invention: the mounting frame is provided with a collection box, and the conveyor belt is provided with a number of sieve holes. The collection box is used to collect impurities that fall through the sieve holes.

[0014] The beneficial effects of this invention are: (1) The present invention sets up a sliding plate and a flip plate. The sliding plate is slidably installed at the bottom of the feeding hopper. The sliding plate has a feeding hole, which corresponds to the flip plate. When the sliding plate slides to the point where the feeding hole coincides with the flip plate, the flip plate flips down and opens, realizing intermittent quantitative feeding. Compared with the traditional method of pushing tea leaves directly from the bottom of the hopper with a partition, this invention effectively avoids the tea leaves from being damaged by squeezing and friction, and improves the appearance quality and yield of the tea leaves.

[0015] (2) The present invention sets up a material equalization component, which includes a hinge plate and a material equalization plate. The material equalization plate abuts against the conveyor belt and is equipped with a material equalization rake. When the slide plate rebounds and resets, the material equalization rake pulls the excess tea leaves between the adjacent partitions downward and pops them out obliquely, so that the tea leaves are evenly distributed between the lower partitions. At the same time, the material equalization plate rebounds and compresses the air, causing the spring plate to flip and spray out high-pressure gas, which helps the tea leaves to pop out obliquely downward. This effectively avoids the excess tea leaves from rolling downward and causing squeezing damage, and achieves uniform feeding of tea leaves, ensuring the processing effect of subsequent processes.

[0016] (3) The present invention opens an air cavity in the slide plate, and opens a connecting hole at the bottom of the flip plate, opens a connecting cavity inside, and opens several air jet holes at the top. When used with an air pump, the air cavity first connects with the air pump during the movement of the slide plate, and then connects with the connecting hole, so that the air jet holes spray air onto the tea leaves in the upper hopper located at the flip plate, so that the tea leaves are loosened, making it easier for the tea leaves to fall and avoid blockage; when the slide plate moves back, it sprays air again to blow the tea leaves in the gap between the flip plate and the upper hopper upward, so as to avoid squeezing the tea leaves when the flip plate closes, further reducing the breakage rate of the tea leaves and ensuring smooth and uniform feeding.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1-8 As shown, an automatic feeding device for tea processing includes a support 1 and a mounting bracket 2 installed on the support 1. The device also includes: Conveyor belt 3 is rotatably mounted on mounting frame 2, and several partitions 31 are evenly distributed on conveyor belt 3; The drive component 4 is mounted on the mounting frame 2 and is connected to the conveyor belt 3 for transmission. Protective plate 5 is installed on mounting frame 2 and located on both sides of conveyor belt 3; The feeding hopper 6 is installed at an angle inside the protective plate 5 and above the conveyor belt 3. The bottom of the inclined cavity of the feeding hopper 6 is equipped with a tilting plate 61. A sliding plate 7 is slidably installed at the bottom of the hopper 6. A discharge hole 71 is provided on the sliding plate 7. The discharge hole 71 corresponds to the tilting plate 61 vertically. When the sliding plate 7 slides to the point where the discharge hole 71 coincides with the tilting plate 61, the tilting plate 61 flips downward and opens. An elastic telescopic plate 9 is installed between the sliding plate 7 and the hopper 6. The material distribution assembly 8 includes a hinge plate 81 and a material distribution plate 82. The hinge plate 81 is rotatably mounted on the end of the slide plate 7. The material distribution plate 82 is connected to the hinge plate 81 and abuts against the conveyor belt 3. The material distribution plate 82 is provided with a material distribution rake 84 for processing excess tea leaves. Hook plates 83 are symmetrically provided on the material distribution plate 82.

[0022] In practical application, tea leaves are poured into the feeding hopper 6, and then the drive unit 4 is activated to rotate the conveyor belt 3. During the rotation of the conveyor belt 3, the partition 31 on the conveyor belt 3 moves with the conveyor belt 3. When the partition 31 moves to the hook plate 83, the partition 31 hooks the hook plate 83 and pulls the hook plate 83 to move. The hook plate 83 then pulls the sliding plate 7 to move through the equalizing plate 82 and the hinge plate 81. When the discharge hole 71 is aligned with the tilting plate 61, the sliding plate 7 releases its support for the tilting plate 61, and the tilting plate 61 tilts downward to open the bottom outlet of the feeding hopper 6. The tea leaves inside fall downward onto the conveyor belt 3. When the sliding plate 7 moves to its limit, due to the contact surface between the hook plate 83 and the partition 31... The surface is curved, allowing the hook plate 83 to slide along the surface of the partition 31 until it separates from the partition 31. Under the rebound action of the elastic telescopic plate 9, the slide plate 7, hinge plate 81, and material equalization plate 82 return to their original positions. At this time, the discharge hole 71 is misaligned with the tilting plate 61, and the slide plate 7 presses the tilting plate 61 to rotate upward, closing the bottom outlet of the feeding hopper 6. This process achieves intermittent feeding, allowing the tea leaves to fall intermittently onto the conveyor belt 3. Compared with existing technologies, this effectively avoids the tea leaves being squeezed and damaged by friction. At the same time, the intermittent feeding of tea leaves onto the conveyor belt 3 can prevent excessive tea leaves between adjacent partitions 31, thus preventing excess tea leaves from rolling downward and further damaging the tea leaves. In addition, during the rotation of the conveyor belt 3, excess tea leaves between adjacent partitions 31 will be scraped off by the material distribution rake 84, causing the excess tea leaves to fall between the adjacent partitions 31 below, thereby ensuring uniform feeding.

[0023] Furthermore, both outer edges of the conveyor belt 3 are provided with outer edge strips 33, and an elastic element 85 is connected between the back of the hinge plate 81 and the feeding hopper 6. The hook plate 83 elastically abuts against the outer edge strip 33, wherein the partition plate 31 is located on the path of the outer edge strip 33.

[0024] The uniform material plate 82 is slidably installed inside the hinge plate 81, and an elastic element 811 connects the hinge plate 81 and the uniform material plate 82.

[0025] In practical application, when the partition 31 hooks the hook plate 83 and pulls the hook plate 83 to move, the hook plate 83 drives the material leveling plate 82 to move outward toward the hinge plate 81, thereby stretching the elastic element 811. When the hook plate 83 moves to its limit position, the hinge plate 81 drives the slide plate 7 to move, while the elastic telescopic plate 9 is compressed. When the slide plate 7 moves to its limit, the hook plate 83 slides along the surface of the partition 31 until the hook plate 83 separates from the partition 31. At this time, the hook plate 83 is released from its restriction, and under the rebound action of the elastic element 811 and the elastic telescopic plate 9, the slide plate 7 and the material leveling plate 82 quickly retract. During this process, the material leveling plate... The rake 84 first scrapes off the excess tea leaves, then moves diagonally upward along the partition 31. When the hook plate 83 passes the partition 31, the excess tea leaves will be bounced downward during the rebound of the equalizing plate 82, so that the excess tea leaves fall into one or more compartments below in a free fall manner, thereby effectively preventing the excess tea leaves from rolling downward and further effectively preventing the excess tea leaves from being squeezed and rubbed. After the hook plate 83 passes the partition 31, it will quickly abut against the outer edge strip 33 under the action of the elastic element 85, so that the hook plate 83 can be hooked and moved by the next partition 31. At the same time, the outer edge strip 33 also protects the conveyor belt 3.

[0026] Furthermore, a flow channel 821 is provided inside the material equalization plate 82, which is connected to the inner cavity of the hinge plate 81. The other end of the flow channel 821 is located inside the material equalization rake 84. A second spring piece 841 is elastically rotatably installed on the material equalization rake 84 at the position corresponding to the end of the flow channel 821. The second spring piece 841 always tends to rotate inward toward the flow channel 821. Several first spring pieces 812 are elastically rotatably installed on the hinge plate 81. The first spring pieces 812 always tend to rotate outward toward the hinge plate 81. When the material equalization plate 82 moves outward toward the hinge plate 81, air pushes several first spring pieces 812 into the inner cavity of the hinge plate 81. When the material equalization plate 82 moves inward toward the hinge plate 81, air enters the flow channel 821 and pushes the second spring piece 841 to flip and spray out.

[0027] In practical application, when the partition 31 hooks the hook plate 83 and moves, the material distribution plate 82 extends out from the hinge plate 81. At this time, the internal pressure of the hinge plate 81 decreases, and the external air pushes the spring piece 812 to flip and enter the hinge plate 81. When the hook plate 83 passes the partition 31, the material distribution plate 82 quickly retracts into the hinge plate 81, and the pressure inside the hinge plate 81 increases instantly. The internal air enters the flow channel 821 and pushes the spring piece 841 to flip and spray out. During this process, excess tea leaves are just bounced away. The sprayed high-pressure air can further make the excess tea leaves fall into one or more compartments below, further effectively preventing the excess tea leaves from rolling down and further effectively preventing the excess tea leaves from being squeezed and damaged by friction.

[0028] like Figure 1 , Figure 4 and Figure 8 As shown, an air chamber 73 is provided inside the slide plate 7. The air chamber 73 is located near the material equalization component 8. A connecting hole 611 is provided at the bottom of the flip plate 61, a connecting cavity 612 is provided inside, and several air jet holes 613 are provided at the top. An air pump 10 is installed on the side of the protective plate 5. When the slide plate 7 moves obliquely upward, the air chamber 73 first connects to the output end of the air pump 10, and then connects to the connecting hole 611. When the air chamber 73 passes the connecting hole 611, the air chamber 73 is disconnected from the air pump 10.

[0029] In practical application, when the hinge plate 81 pulls the slide plate 7 to move obliquely upward, the air chamber 73 will connect with the air pump 10 and then with the connecting hole 611. When the air chamber 73 is connected with the connecting hole 611, the tilting plate 61 is still supported by the slide plate 7 and has not yet fully tilted downward. At this time, the air pumped by the air pump 10 will be ejected from several air jet holes 613 through the air chamber 73, the connecting hole 611 and the connecting chamber 612. The ejected air acts on the tea leaves located at the tilting plate 61 in the feeding hopper 6, making the tea leaves at that location loose and preventing the tea leaves from accumulating and blocking at the tilting plate 61. This ensures smooth feeding on the one hand and uniform feeding on the other hand, so that the amount of tea leaves distributed between adjacent partitions 31 is uniform. When the feeding hole 71 coincides with the tilting plate 61, the tilting plate 61 tilts downward, and the tea leaves fall onto the conveyor belt 3. As the slide plate 7 springs back to its original position, the air chamber 73 connects to the air pump 10, and then gradually connects to the connecting hole 611. At this time, the flip plate 61 is not completely closed. The air pumped by the air pump 10 is ejected from the jet hole 613. The ejected air acts on the tea leaves in the gap between the flip plate 61 and the bottom of the feed hopper 6, blowing the tea leaves in the gap upwards. This prevents the tea leaves in the gap from being squeezed when the flip plate 61 flips up and closes, thus preventing the tea leaves from being squeezed and damaged when the flip plate 61 closes.

[0030] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a collection chamber 72 is provided inside the slide plate 7. The collection chamber 72 is opposite to the air chamber 73 across the discharge hole 71. An inclined filter plate 721 is provided on the side of the collection chamber 72 near the discharge hole 71.

[0031] The path of the flip plate 61 flipping downwards coincides with the inclined end of the filter plate 721.

[0032] The mounting frame 2 is equipped with a collection box 21, and the conveyor belt 3 has several sieve holes 32. The collection box 21 is used to collect impurities that fall through the sieve holes 32.

[0033] In practical application, after the flip plate 61 flips downward, the tea leaves first fall onto the filter plate 721. After being filtered by the filter plate 721, the fine impurities in the tea leaves pass through the filter holes of the filter plate 721 and enter the collection chamber 72 for collection. The tea leaves then continue to roll down along the inclined surface of the filter plate 721 and fall between the two sets of adjacent partitions 31 on the conveyor belt 3. When the flip plate 61 moves to the inclined end of the filter plate 721, it will hit the end of the filter plate 721, thereby causing the filter plate 721 to vibrate. This allows the impurities blocked in the filter holes to pass through the filter plate 721 and enter the collection chamber 72, ensuring the filtration effect of the filter plate 721. When the hook plate 83 falls back onto the outer edge strip 33, the vibration generated by the elastic element 85 rebounding and causing the material leveling plate 82 to retract, as well as the impact of the hook plate 83 falling back, causes the conveyor belt 3 to vibrate slightly. Under the vibration, the tea leaves on the conveyor belt 3 pass through the sieve holes 32 on the conveyor belt 3 and fall into the collection box 21 at the bottom of the mounting frame 2, thus achieving further separation of tea leaves and impurities.

[0034] Working Principle: When the device is working, the tea leaves to be processed are first poured into the feeding hopper 6, and then the drive unit 4 is started, which drives the conveyor belt 3 to rotate. During the operation of the conveyor belt 3, the partition plate 31 on it moves synchronously with the conveyor belt 3. When the partition plate 31 moves to the material equalization component 8, it hooks the hook plate 83 on the material equalization plate 82 and pulls the hook plate 83 to move. The hook plate 83 pulls the slide plate 7 through the material equalization plate 82 and the hinge plate 81, so that the slide plate 7 slides obliquely upward at the bottom of the feeding hopper 6. During the sliding of the slide plate 7, its internal air chamber 73 first connects to the output end of the air pump 10 on the side of the protective plate 5, and then connects to the connecting hole 611 at the bottom of the tilting plate 61. At this time, the flip plate 61 is still supported by the slide plate 7 and has not been fully flipped. The air pumped out by the air pump 10 passes through the air chamber 73, the connecting hole 611 and the connecting cavity 612 inside the flip plate 61, and finally sprays out from several air jet holes 613 on the top of the flip plate 61, acting on the tea leaves at the flip plate 61, making the tea leaves at that place loose and preventing them from accumulating and clogging. When the slide plate 7 continues to slide until the discharge hole 71 on it is completely aligned with the tilting plate 61, the slide plate 7 releases its support for the tilting plate 61. Under the action of gravity, the tilting plate 61 tilts downward and opens, allowing the tea leaves in the feed hopper 6 to fall downward through the discharge hole 71. The tea leaves first fall onto the filter plate 721 on one side of the collection chamber 72 opened in the slide plate 7. After being filtered by the filter plate 721, the fine impurities in the tea leaves pass through the filter holes and enter the collection chamber 72 for collection. The tea leaves then continue to slide down the inclined surface of the filter plate 721 onto the conveyor belt 3 and are located between two sets of adjacent partitions 31. When the tilting plate 61 tilts downward to its limit position, it will hit the inclined end of the filter plate 721, causing the filter plate 721 to vibrate and shake the impurities blocking the filter holes into the collection chamber 72, ensuring the filtration effect of the filter plate 721. When the slide plate 7 moves to its limit position under the pull of the hook plate 83, the contact surface (arc surface) between the hook plate 83 and the partition plate 31 begins to slide relative to each other until the hook plate 83 and the partition plate 31 are completely separated. At this time, the slide plate 7 quickly returns to its original position under the rebound action of the elastic telescopic plate 9. At the same time, the material distribution plate 82 also quickly retracts into the hinge plate 81 under the rebound action of the elastic element 1 811 and the elastic element 2 85. During this process, the material distribution rake 84 on the material distribution plate 82 first scrapes off the excess tea leaves between the adjacent partition plates 31, and then, during the rapid rebound, bounces these excess tea leaves diagonally downwards, allowing them to fall into one or more compartments below in a free-fall manner. At the same time, as the material distribution plate 82 rapidly retracts into the hinge plate 81, the internal pressure of the hinge plate 81 increases instantaneously, and the air inside is forced into the flow channel 821 in the material distribution plate 82, pushing the spring 841 to flip. High-pressure air is ejected from the material distribution rake 84, further assisting the excess tea leaves to fall diagonally downwards, achieving uniform distribution. During the reset process of the slide plate 7, its internal air chamber 73 reconnects with the air pump 10 and gradually connects with the connecting hole 611. At this time, the tilting plate 61 is not completely closed, and the air pumped by the air pump 10 is ejected from the jet hole 613, blowing the tea leaves at the gap between the tilting plate 61 and the bottom of the feeding hopper 6 upwards. Subsequently, the slide plate 7 continues to reset, and its end pushes the tilting plate 61 to rotate upwards until the bottom outlet of the feeding hopper 6 is completely closed, completing one work cycle. When the hook plate 83 separates from the partition plate 31 and falls back onto the outer edge strip 33 on the outside of the conveyor belt 3, the impact and vibration generated are transmitted to the conveyor belt 3, causing the tea leaves on the conveyor belt 3 to vibrate slightly. The fine impurities in the tea leaves fall into the collection box 21 at the bottom of the mounting frame 2 through the sieve holes 32 on the conveyor belt 3, achieving further separation from the tea leaves. The conveyor belt 3 continues to operate, and the hook plate 83 remains abutted against the outer edge strip 33 under the action of the elastic element 85, waiting for the next partition plate 31 to hook it, thereby achieving continuous, automatic and uniform feeding operation.
