Description

Technical Field

[0001] The present invention belongs to the technical field of tea conveying equipment, and particularly relates to a tea conveying device with blending function and its conveying method. Background Art

[0002] Tea conveying devices are key equipment for realizing automatic material transfer during the tea processing process. These devices not only improve production efficiency, reduce manual operations, but also ensure the smooth transition of tea between different processes. For different stages in the tea production process, different conveying devices are required. After the tea is dried, in order to reduce costs and increase efficiency, and enhance the compound fragrance of the tea, different teas are usually blended and conveyed. The following problems exist in the current tea blending and conveying:

[0003] 1. During the process of blending and conveying tea, different teas are usually added to the feeding conveyor, and then conveyed to the blending and mixing device through the feeding conveyor. The stirring mechanism in the blending and mixing device is used to mix and stir the tea to achieve the blending of the tea. The dried tea is relatively brittle. Using this kind of blending and mixing method is likely to cause the tea to break, reducing the quality of the tea.

[0004] 2. After different teas are conveyed onto the feeding conveyor, the teas are stacked together, and different teas form layers, increasing the difficulty of subsequent blending and mixing and reducing the uniformity of subsequent mixing.

[0005] 3. In order to prevent the occurrence of excessive oxidation of the tea, it is necessary to cool down the tea during the tea conveying process after drying. The commonly used cooling method is to use a blower to blow air from the top for cooling during the conveying process. However, the teas are stacked together. When using top blowing for cooling, the surface temperature of the tea drops while the deep layer temperature is still relatively high, making it difficult to cool the deep-layer tea in the stack, and the cooling effect is poor.

[0020] A tea conveying method with blending function, based on a tea conveying device with blending function described in any one of the above, this tea conveying method with blending function includes the following steps:

[0021] S1. Tea conveying and feeding: First, use a hoist to evenly feed part of the tea onto a belt conveyor, and the belt conveyor drives part of the tea to be conveyed from right to left;

[0022] S2. Vibration and even blending: The remaining part of the tea to be blended is fed onto the blending mechanism through a metering feeder. The blending mechanism conveys through vibration and evenly spreads the tea to be blended on top of the tea on the belt conveyor, realizing the quantitative blending of the tea;

[0023] S3. Reciprocating leveling and cooling: The blended tea is conveyed to the area of the reciprocating feeding mechanism, and the reciprocating feeding mechanism is used to reciprocally stir the stacked tea in a staggered manner, realizing the preliminary mixing of the tea, and at the same time realizing the internal blowing and heat dissipation of the stacked tea;

[0024] S4. Mixing and cooling: The tea after preliminary mixing and heat dissipation enters the mixing mechanism through a collecting hopper.

The tea after heat dissipation is filtered and then conveyed to the next step;

[0025] S5. Automatic slag discharge: The filtered tea residue is scraped by the automatic slag discharge component and automatically discharged through the slag discharge hopper.

[0026] The beneficial effects of the present invention are as follows:

[0027] 1. Through the setting of the vibration conduction component in the present invention, the vibration conveying of the tea to be blended is realized, and the tea to be blended is evenly spread on top of the original tea on the belt conveyor. During the vibration conveying process, the vibration conduction component transfers the vibration to the conveyor belt of the belt conveyor, and uses vibration to realize the vibration mixing of the tea, realizing the primary mixing of the tea, and the screening and conveying component in the blending mechanism realizes the screening of the tea to be blended, reducing the content of tea residue.

[0028] 2. Through the reciprocating feeding mechanism to reciprocally stir the blended tea in a staggered manner in the present invention, the secondary mixing of the tea is realized. During the stirring process, the tea stacked inside is turned out, improving the heat dissipation effect of the tea. And during the reciprocating stirring process, the air blowing and cooling component is synchronously squeezed, and cold air is directly blown into the stacked tea through the air permeable holes, realizing the blowing and cooling from the inside to the outside, and realizing the primary cooling of the tea.

[0029] 3. The tea leaves of the present invention enter the mixing mechanism. Through the setting of the spiral mixing component and the spiral plate, the spiral mixing of the tea leaves is achieved, replacing the stirring mixing method, reducing the probability of tea leaf breakage, realizing the three-stage mixing of the tea leaves, achieving the multi-stage mixing of the tea leaves, improving the mixing uniformity. At the same time, the spiral cooling component generates a spiral air flow, realizing the air flow mixing of the tea leaves, further improving the mixing uniformity. And when the spiral air flow mixes, it simultaneously takes away the heat on the tea leaves, realizing the secondary cooling. The spiral mixing component simultaneously drives the automatic slag discharging component to work, realizing the automatic discharge of the filtered tea leaf residue.

A collecting hopper 4 is fixedly installed on the left side of the belt conveyor 1, and a mixing mechanism 5 for mixing the tea is arranged below the collecting hopper 4 on the left side of the belt conveyor 1.

[0046] During use, a feeding elevator (not shown in the figure) evenly feeds the dried tea onto the belt conveyor 1. The belt conveyor 1 conveys the tea from right to left. The blending mechanism 3 vibrates and conveys other teas to be blended, conveys them onto the belt conveyor 1, and evenly spreads them on the top of the tea on the belt conveyor 1. The reciprocating feeding mechanism 2 is used to realize the reciprocating feeding and mixing of the tea and preliminary heat dissipation. The mixing mechanism 5 is used to realize the uniform mixing and sufficient heat dissipation of the tea. The number of the blending mechanisms 3 is increased or decreased according to the number of types of teas to be blended.

[0047] Please refer to Figure 1 and Figure 2 , The blending mechanism 3 includes a vibration component 31, a screening and conveying component 32, and a vibration conduction component 33. The screening and conveying component 32 and the vibration conduction component 33 are both arranged on the vibration component 31. The vibration component 31 includes two brackets 311 symmetrically arranged front and rear. A bottom plate 313 is jointly installed at the tops of the two brackets 311. A number of first springs 312 are fixedly installed on the top of the bottom plate 313. A top plate 314 is jointly arranged at the tops of the multiple first springs 312. A vibration motor 315 is fixedly installed at the rear side of the top of the top plate 314.

[0048] Please refer to Figure 2 , The screening and conveying component 32 includes a number of elastic support plates 321 fixedly installed on the top of the top plate 314. The multiple elastic support plates 321 are grouped in pairs and are symmetrically distributed left and right. A material receiving hopper 322 is jointly arranged at the tops of the multiple elastic support plates 321. A sieve plate 323 is arranged at the top inside the material receiving hopper 322. A baffle 326 is fixedly installed at the front side between the material receiving hopper 322 and the sieve plate 323. A discharge pipe 327 is fixedly installed at the front side of the bottom of the material receiving hopper 322. A collecting bucket for collecting tea residues is arranged at the bottom of the discharge pipe 327. A number of supports 324 are fixedly installed at the middle of the bottom of the material receiving hopper 322 and at the middle of the top of the top plate 314. A second spring 325 is jointly fixedly installed between the two supports 324 corresponding up and down.

[0049] Please refer to Figure 2The vibration conduction component 33 includes a No. 2 L-shaped plate 332 fixedly connected to the front center of the top plate 314.

The roller 331 is located between the upper and lower conveyor belts of the belt conveyor 1, and the top of the roller 331 is in contact with the bottom of the upper conveyor belt.

[0050] When the blending mechanism 3 is in use, first, the quantitative lower hopper quantitatively puts the tea leaves to be blended onto the sieve plate 323, and then the vibration motor 315 is started. The vibration motor 315 generates linear vibration, and the vibration is transmitted to the elastic support plate 321 and the second spring 325 through the top plate 314, and then transmitted to the receiving hopper 322 and the sieve plate 323, thereby driving the tea leaves to be vibrated and transported from back to front along the sieve plate 323. During the vibration process, the tea residues are screened by the sieve plate 323 and enter the bottom of the receiving hopper 322. The screened tea leaves are transported by vibration, which can ensure that the tea leaves are evenly delivered to the top of the tea leaves on the belt conveyor 1, thereby achieving uniform blending of the tea leaves. The tea residues are also transported by vibration to the discharge pipe 327 and discharged into the collection bucket for collection. When the top plate 314 vibrates, the vibration is indirectly transmitted to the roller 331 through the second L-shaped plate 332, and then the bottom of the top conveyor belt of the belt conveyor 1 is vibrated, so that the tea leaves on the conveyor belt are vibrated, thereby achieving vibration mixing of the tea leaves and achieving primary mixing of the tea leaves.

[0054] When in use, the No. 1 servo motor 211 is started, and the output end of the No. 1 servo motor 211 drives the limit plate 213 and the fixed pin 218 thereon to rotate. Since the fixed pin 218 slides inside the limit slide groove on the limit plate 213, the limit plate 213 and the pad 217 thereon are reciprocated in the front and rear directions, and at the same time, one of the racks 214 and the corresponding U-shaped frame 212 thereon are reciprocated, and at the same time, the reciprocating rotation of the No. 1 gear 215 is driven, and the other rack 214 and the corresponding U-shaped frame 212 thereon are synchronously driven to reciprocate in the opposite direction, so that the two U-shaped frames 212 are reciprocated in an alternating manner. , and at the same time, the connecting tube 242 and the dial tube 241 thereon are driven to move back and forth, and the dial tube 241 is used to realize the reciprocating mixing of the tea leaves, thereby realizing the secondary mixing of the tea leaves, and at the same time, the tea leaves stacked at the bottom are flipped to the top to facilitate heat dissipation. When the U-shaped frame 212 reciprocates, the fixed frame 244 and the pressing plate 246 thereon are synchronously driven to reciprocate, and the pressing plate 246 squeezes the air bag 245. The air bag 245 indirectly transports the cold air from the rubber hose 247 to the dial tube 241, and the cold air is sprayed out from the air hole at the bottom of the dial tube 241, thereby realizing the heat dissipation of the tea leaves by blowing air inside while the material is being dialed, thereby realizing the primary heat dissipation from the inside to the outside.

A fixed head 575 is fixedly installed outside the fixed collar 574. A scraping plate 577 is fixedly installed at the bottom of one side of the fixed head 575 away from the fixed collar 574. The bottom of the scraping plate 577 is attached to the top of the slag blocking plate 570. A second guiding rod 578 is fixedly installed at the top of one side of the fixed head 575 away from the fixed collar 574. A blocking block (not shown in the figure) is installed at the end of the second guiding rod 578 away from the fixed head 575. A movable block 576 is slidably sleeved on the second guiding rod 578. A scraping block 579 is fixedly installed on one side of the movable block 576. The bottom of the scraping block 579 is attached to the top of the slag blocking plate 570. One side of the scraping block 579 is a plane, and the other side is a fan-shaped surface. A second fixed seat is fixedly installed on the top of the movable block 576. A connecting rod 572 is hinged to the top of the second fixed seat. The top of the connecting rod 572 is rotatably connected to a slider 573. A circular slide rail 571 is fixedly installed at the lower part of the inner wall of the mixing tank 52. The circular slide rail 571 is eccentrically arranged on the mixing tank 52. The slider 573 is slidably connected inside the circular slide rail 571.

[0058] During use, first start the second servo motor 531. The output end of the second servo motor 531 drives the connecting shaft 533 and the screw shaft 534 thereon to rotate. The blended tea leaves are conveyed to the aggregate hopper 4 through the belt conveyor 1, and then enter the mixing box 52 through the collection of the aggregate hopper 4. The arc-shaped plate 51 is used to prevent the tea leaves from falling out of the mixing box 52. After the tea leaves enter the mixing box 52, they do a free-fall motion. Through the spiral guidance of the spiral plate 58 and the rotation of the screw shaft 534, the spiral mixing of the tea leaves is achieved. Compared with the stirring mixing method, the probability of tea leaf breakage is reduced. At the same time when the connecting shaft 533 rotates, start the air pump 551 to convey the cooling air flow into the annular shunt plate 552. After being shunted by the annular shunt plate 552, it is ejected through the cooling pipe 553 to form a spiral air flow. The spiral air flow further improves the uniformity of tea leaf mixing and realizes the uniform and rapid cooling of the tea leaves. The intensity of the spiral air flow is adjustable and will not cause the situation where the tea leaves cannot fall. After cooling and mixing, the tea leaves are discharged from the discharge hopper 54 after being filtered by the inclined filter screen 532. The tea leaves enter the next production step. The filtered tea leaf residues fall onto the slag retaining plate 570. At this time, under the rotation of the connecting shaft 533, the fixed collar 574 and the fixed head 575 thereon are driven to rotate synchronously, and at the same time, the scraper 577 is driven to scrape the top of the slag retaining plate 570. At the same time, the movable block 576 and the connecting rod 572 thereon are driven to rotate synchronously, and at the same time, the slider 573 is driven to rotate. Since the slider 573 is slidably connected inside the circular slide rail 571, when the scraper 577 rotates around the axis of the connecting shaft 533, the movable block 576 is driven to slide along the direction of the second guide rod 578, and then the scraping block 579 is driven to slide along the direction of the second guide rod 578. At this time, the straight surface of the scraping block 579 contacts the tea leaf residues, so as to scrape the tea leaf residues into the slag discharge hopper 56 for discharge, realizing the automatic discharge of the tea leaf residues, reducing the residue of the tea leaf residues. At the same time, since one side of the scraping block 579 is a straight surface and the other side is a fan-shaped surface, when the scraping block 579 makes a half-turn backward movement after scraping, the fan-shaped surface of the scraping block 579 contacts the tea leaf residues, so the fan-shaped surface of the scraping block 579 squeezes the un-scraped tea leaf residues in the direction away from the scraper 577, so that the un-discharged tea leaf residues are discharged during the second circle of scraping.

[0059] It should be noted that for a tea conveying device with blending function, when in use, first, the dried tea is evenly fed onto the belt conveyor 1 by the feeding elevator. The belt conveyor 1 conveys the tea from right to left. Subsequently, the blending mechanism 3 uses the vibration conveying method to evenly spread the tea to be blended on the top of the tea on the belt conveyor 1. The vibration conduction component 33 in the blending mechanism 3 synchronously drives the top conveyor belt of the belt conveyor 1 to vibrate, realizing the primary vibration mixing of the tea. As the belt conveyor 1 continues to convey, the reciprocating component 21 in the reciprocating feeding mechanism 2 reciprocally stirs and mixes the blended tea, and at the same time turns the tea stacked at the bottom to the upper part for heat dissipation. When the U-shaped frame 212 reciprocates, it synchronously drives the fixed frame 244 and the pressing plate 246 thereon to reciprocate. The pressing plate 246 squeezes the airbag 245, and the airbag 245 indirectly conveys the cold air into the dialing pipe 241 through the rubber hose 247 and sprays it out from the air holes at the bottom of the dialing pipe 241, thus realizing blowing heat dissipation inside the tea while feeding, achieving the primary heat dissipation from the inside out. At the same time, as the belt conveyor 1 continues to convey, the tea enters the mixing box 52 through the collection of the aggregate hopper 4. After the tea enters the mixing box 52, it makes a free-fall motion. Through the spiral guiding of the spiral plate 58 and the rotation of the spiral shaft 534, the spiral mixing of the tea is realized. Compared with the stirring and mixing method, the probability of tea breakage is reduced, and at the same time, the tertiary mixing of the tea is realized. During the mixing, the spiral cooling component 55 generates a spiral air flow, which further improves the uniformity of the tea mixing and realizes the uniform and rapid cooling of the tea. After cooling and mixing, the tea is filtered through the inclined filter screen 532 and discharged from the discharge hopper 54, and the tea enters the next production step. The tea residue is automatically discharged and collected through the automatic slag discharging component 57.

[0060] Please refer to Figure 13 , a tea conveying method with blending function, based on the above-mentioned tea conveying device with blending function, the tea conveying method with blending function includes the following steps:

[0061] S1. Tea conveying and feeding: First, use the elevator to evenly feed part of the tea onto the belt conveyor 1, and the belt conveyor 1 drives part of the tea to convey from right to left.

[0062] S2. Vibration and uniform blending: The remaining part of the tea to be blended is fed onto the blending mechanism 3 through the quantitative feeding machine. The blending mechanism 3 spreads the tea to be blended evenly on the top of the tea on the belt conveyor 1 through vibration conveying, realizing the quantitative blending of the tea.

[0063] S3. Reciprocating leveling and cooling: The blended tea is conveyed to the area of the reciprocating feeding mechanism 2, and the reciprocating feeding mechanism 2 is used to reciprocate and stir the stacked tea in a staggered manner to achieve the preliminary mixing of the tea, and at the same time, internal air blowing and heat dissipation are carried out on the stacked tea.

[0064] S4. Mixing and cooling: The tea after preliminary mixing and heat dissipation enters the mixing mechanism 5 through the aggregate hopper 4. The mixing mechanism 5 performs spiral mixing on the blended tea, and at the same time, spiral air flow is used to mix the tea in a spiral air flow, and at the same time, the tea is fully cooled. The cooled tea is filtered and then conveyed to the next step.

[0065] S5. Automatic slag discharge: The filtered tea residue is scraped by the automatic slag discharge component 57 and automatically discharged through the slag discharge hopper 56.
