Description

Technical Field

[0001] This utility model relates to the technical field of tea leaf blending equipment, and in particular to an online blending equipment with a multi-head flow metering combination. Background Technology

[0002] The traditional blending process for whole leaves of scented tea (such as jasmine tea blending) involves: several sets of feeding conveyors and belt scales at the front end. A belt conveyor line is installed below the belt scale outlet. The feeding conveyors transport the tea leaves to the belt scales, and the weighed tea leaves are fed at a uniform speed to the lower belt conveyor line. Multiple sets of tea leaves weighed by the belt scales are stacked layer by layer on the belt conveyor line to complete the initial blending. A leveling bin is located below the outlet of the belt conveyor line. The tea leaves from the initial blending are stacked layer by layer in the leveling bin for secondary blending. A conveyor at the bottom of the leveling bin sends the tea leaves to a sorting machine for magnetic and color sorting. Then, the tea leaves proceed through the assembly line to the next process for packaging and palletizing.

[0003] During the secondary blending process, multiple belt scales and conveyor lines pause while the previous batch of tea leaves is stacked in the blending silo for the next batch of tea leaves. Only after the previous batch of tea leaves has been blended and sent to the sorting machine can the blending silo be emptied and filled with new tea leaves for the next batch of "secondary blending." The traditional jasmine tea blending process involves discontinuous production steps, low capacity, and inaccurate proportions due to the use of belt scales and blending silos for the secondary blending of multiple tea leaves.

[0004] Therefore, improving the accuracy of the blending ratio of whole tea leaves and increasing production capacity have become technical problems that need to be solved. Utility Model Content

[0005] The purpose of this invention is to provide an online blending device with multiple flow metering units, which mainly solves the problem of how to improve the accuracy of the blending ratio and increase the production capacity of the above-mentioned existing technologies.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: an online mixing device with multiple flow metering units, characterized in that: the online mixing device with multiple flow metering units includes a feeding hopper, a first feeding conveyor, a first vibrating feeder, a combined scale, a chute, a consolidating belt conveyor, a second feeding conveyor, and a mixer. The discharge port of the feeding hopper is connected to the inlet of the first feeding conveyor, the discharge port of the first feeding conveyor corresponds to the inlet of the first vibrating feeder, the discharge port of the first vibrating feeder corresponds to the inlet of the combined scale, the discharge port of the combined scale corresponds to the inlet of the chute, the discharge port of the chute is connected to the consolidating belt of the consolidating belt conveyor, the consolidating belt conveyor transports the received material to the inlet of the second feeding conveyor, and the discharge port of the second feeding conveyor is connected to the inlet of the mixer.

[0007] Furthermore, each combined scale is set up with several zones, and each zone corresponds to a set of feeding bins, a first feeding conveyor and a first vibrating feeder.

[0008] Furthermore, a second vibrating feeder is installed between the chute and the consolidating belt conveyor. The discharge port of the chute corresponds to the inlet of the second vibrating feeder, and the discharge port of the second vibrating feeder corresponds to the consolidating belt of the consolidating belt conveyor.

[0009] Furthermore, the online assembly equipment of the multi-head flow metering combination includes several combined scales, with two adjacent combined scales forming a group. The two discharge ports of the two second vibrating feeders corresponding to each group of two combined scales correspond to a collection chute inlet, and the discharge port of the collection chute corresponds to the collection belt of the collection conveyor.

[0010] Furthermore, the mixer is a drum mixer.

[0011] Furthermore, the online assembly equipment for this multi-head flow metering system includes six combined scales, each of which is divided into four zones.

[0012] Furthermore, the online assembly equipment for this multi-head flow metering combination also includes a dust collector, which corresponds to the end of the collection belt conveyor;

[0013] Furthermore, the combined scale also includes a top cone, a vibration mechanism, a feeding hopper, a metering hopper, a collecting hopper, and a control mechanism. The material in the feed inlet of the combined scale falls onto the top cone, the material on the top cone falls onto the vibration mechanism, and the material in the vibration mechanism falls into the corresponding metering hopper for weighing. The control mechanism of the combined scale selects the weight combination of the material in the corresponding metering hopper and discharges it into the chute. During the falling process of the material in the chute, it is initially combined. The initially combined material falls into the collecting hopper of the combined scale through the discharge port of the chute. After the material is collected by the collecting hopper, it falls from the collecting hopper to the collecting belt of the converging conveyor.

[0014] In view of the above technical features, the present invention has the following beneficial effects:

[0015] 1. This utility model discloses an online blending device with a multi-head flow metering system. It utilizes several combined scales (with chutes in the combined scales) to accurately measure and initially blend various types of raw tea leaves, improving the accuracy of the blending ratio. A second blending is achieved through a second vibrating feeder and a collecting chute. A third blending is performed through a converging belt conveyor and several collecting chutes. Finally, a fourth blending is achieved by a drum mixer. The entire production process can be continuous and uninterrupted, increasing blending capacity. Compared to existing technologies that use belt scales and uniform stacking bins for secondary blending, this utility model's online blending device with a multi-head flow metering system adds two blending operations, improving the mixing uniformity of various raw tea leaves.

[0022] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0023] See Figures 1 to 4Specific Embodiment 1 provides an online mixing device with multiple flow metering units, including a feeding hopper 1, a first feeding conveyor 2, a first vibrating feeder 3, a combined scale 4, a chute 4-1, a consolidating belt conveyor 5, a second feeding conveyor 6, and a mixer. The discharge port of the feeding hopper 1 is connected to the inlet of the first feeding conveyor 2. The discharge port of the first feeding conveyor 2 corresponds to the inlet of the first vibrating feeder 3. The discharge port of the first vibrating feeder 3 corresponds to the inlet of the combined scale 4. The discharge port of the combined scale 4 corresponds to the inlet of the chute 4-1. The discharge port of the chute 4-1 corresponds to the consolidating belt 5-1 of the consolidating belt conveyor 5. The consolidating belt 5-1 transports the received material to the inlet of the second feeding conveyor 6. The discharge port of the second feeding conveyor 6 is connected to the inlet of the mixer. The mixer is a drum mixer 7. In "multi-head flow metering combination," "flow rate" refers to the weight of the material. The combined scale 4 is used to realize the weight measurement of the material in the multiple scales and the combined weight of the material for feeding. The first vibrating feeder 3 is used to vibrate the material (such as raw tea leaves) conveyed by the first feeding conveyor 2 to disperse the material, so that the material falls into the combined scale 4 more evenly and dispersedly, thereby improving the mixing uniformity of various raw tea leaves.

[0024] The combined scale 4 also includes a top cone (not shown in the attached drawing), a vibration mechanism (not shown in the attached drawing), a feeding hopper 4-2, a metering hopper 4-3, a collecting hopper 4-4, and a control mechanism (not shown in the attached drawing). The material in the feed inlet of the combined scale 4 falls onto the top cone, the material on the top cone falls onto the vibration mechanism, and the material in the vibration mechanism falls into the corresponding metering hopper 4-3 for weighing. The control mechanism of the combined scale selects the weight combination of the material in the corresponding metering hopper 4-3 and discharges it into the chute 4-1. The material in the chute 4-1 is initially combined during the falling process. The initially combined material falls into the collecting hopper 4-4 of the combined scale through the discharge port of the chute 4-1. After the material is collected by the collecting hopper 4-1, the material falls from the collecting hopper 4-4 to the collecting belt 5-1 of the collecting belt conveyor 5.

[0025] Each combined scale 4 is configured with several zones, each zone corresponding to a feeding bin 1, a first feeding conveyor 2, and a first vibrating feeder 3. In this embodiment 1, an online blending device with a multi-head flow metering system includes six combined scales 4. For example, each combined scale 4 is divided into four zones, totaling twenty-four zones. This allows for the use of 24 types of tea leaves as blending raw materials, enabling multi-variety blending. Figure 2 As shown, the first feeding conveyor 2 from 1# to 24# corresponds to the 24 sections of the six combined scales 4, as well as the 24 feeding bins 1 and the 24 first vibrating feeders 3.

[0026] A second vibrating feeder 9 is also installed between chute 4-1 and the consolidating belt conveyor 5. The discharge port of chute 4-1 corresponds to the inlet of the second vibrating feeder 9, and the discharge port of the second vibrating feeder 9 corresponds to the consolidating belt 5-1 of the consolidating belt conveyor 5. The second vibrating feeder 9 is used to vibrate and disperse the material falling from chute 4-1 in the combined scale 4 (such as the tea leaves that have been blended for the first time by the combined scale 4 and chute 4-1), making the material more evenly and dispersedly fall onto the consolidating belt 5-1 of the consolidating belt conveyor 5 through the collecting chute 10, thereby improving the mixing uniformity of various tea leaves. The second blending operation is completed in the collecting chute 10.

[0027] Preferably, the online assembly equipment for multi-head flow metering combinations includes several combination scales 4, with two adjacent combination scales 4 forming a group. In each group of two combination scales 4, the two chutes 4-1 corresponding to the two discharge ports of the second vibrating feeders 9 correspond to the inlet of a collecting chute 10, and the discharge port of the collecting chute 10 corresponds to the collecting belt 5-1 of the collecting conveyor 5. In this embodiment 1, in an online assembly equipment for multi-head flow metering combinations, six combination scales 4 are arranged in pairs, forming three groups in total. See... Figure 2 and Figure 3 .

[0028] In this embodiment 1, an online assembly device for multi-head flow metering includes a dust collector 8. There are two dust collectors 8, which correspond to the ends of the main conveyor belt 5, resulting in a more reasonable spatial arrangement. Dust collector 8 is a dust collection device. During the tea blending process, a lot of tea powder floats in the production workshop. Therefore, the tea production channel needs to be completely enclosed. In addition, dust collector 8, which collects dust and / or powder, is connected to each production device. It collects the tea powder floating in the production channel through air pressure. For example, in this embodiment 1, dust collector 8 is connected to the top of the combined scale through a dust suction pipe and a dust suction hood (not shown in the attached figure) to absorb and collect tea powder generated by the raw tea leaves near the feed port of the combined scale 4; dust collector 8 is connected to the top of the first feeding conveyor 2 through a dust suction pipe and a dust suction hood (not shown in the attached figure) to absorb and collect tea powder generated by the raw tea leaves near the discharge port of the first feeding conveyor 2; dust collector 8 is connected to the enclosed production space where the summarizing belt 5-1 is located through a dust suction pipe (not shown in the attached figure) to absorb and collect tea powder generated by the raw tea leaves on the summarizing belt 5-1, keeping the tea powder content in the tea production channel low, the production environment cleaner, and reducing the adverse effects of tea powder on the production equipment.

[0029] An online blending device with multiple flow metering units can also be adapted to meet the needs of more than 24 kinds of tea leaves as blending raw materials by increasing the number of components such as the combination scale 4, feeding bin 1, first feeding conveyor 2, first vibrating feeder 3, second vibrating feeder 9, and collecting chute 10.

[0030] The working principle of the online blending equipment with multi-head flow metering combination in this embodiment 1 is as follows: After each feeding bin 1 is filled, the corresponding first feeding conveyor 2 transports various tea leaves to the corresponding first vibrating feeder 3. The corresponding first vibrating feeder 3 conveys the corresponding materials to the corresponding section of the corresponding combination scale 4 through vibration. Each combination scale 4 is equipped with four sections, which can weigh four kinds of materials. The combination scale 4 is equipped with a chute 4-1 ( Figure 4 As shown, various raw tea leaves undergo initial blending as they fall through the chute 4-1 of the combined scale 4; then, they undergo a second blending via the second vibrating feeder 9 and the collecting chute 10. Figure 3 As shown, Figure 3 There are six combined scales 4, forming three groups. Every two combined scales 4 share a collection chute 10. The tea leaves then fall onto the collection belt 5-1 of the collection conveyor 5. Different varieties of tea leaves are stacked layer by layer on the collection belt 5-1 to achieve a three-stage blending effect. Then, they are sent to the drum mixer 7 by the second feeding conveyor 6 for mixing, which is the fourth blending. This completes the accurate measurement and blending of multiple varieties of tea leaves. Finally, the blended tea leaves are sent to the next production line for the next production operation. The materials are measured by the combined scales, resulting in high accuracy in the blending ratio. After four blending operations, the materials are mixed more evenly, and the tea leaves after four blending processes have a better taste when brewed.

[0031] This embodiment 1 presents an online blending equipment with a multi-head flow metering system, integrating feeding, metering control, online mixing, and discharging functions. Feeding is achieved using a feeding hopper 1, a first feeding conveyor 2, and a first vibrating feeder 3. Metering control of various materials (such as different types of raw tea leaves) is achieved using a combined scale 4, employing multi-head metering to control the online material flow, which not only improves the accuracy of the proportions but also significantly increases production capacity. Here, "online" means the blending equipment can continuously output materials, enabling continuous production without interruption or waiting time. "Online mixing" means the blending equipment can continuously output blended materials, achieving multiple blending processes (i.e., mixing) during output, enabling continuous production without interruption or waiting time. The converging belt conveyor 5, the second feeding conveyor 6, and the drum mixer 7 not only perform the last two blending operations but also discharge the material that has undergone four blending operations, thus achieving the discharging function.

[0032] In this embodiment 1, a multi-head flow metering combination online blending device utilizes the digital components of the combined scale 4 (such as digital control components like the metering hopper) to achieve precise online metering and blending of materials. This flexibly improves the flexibility and formula diversity of the online blending device, satisfying the balance between the main ingredient of new tea drinks—jasmine fragrance—and the tea flavor, ensuring a light and refreshing main tone and satisfying consumers' color, aroma, and taste experience, which aligns with the current concept of tea drinking for human health.

[0033] In addition, taking the combination of 32 kinds of materials and eight combined scales as an example, the online combination equipment for multi-head flow metering combination occupies a space of 18m long, 5m wide and 6m high, that is, 18m (L) x 6m (H) x 5m (D) = 540m. 3 Compared to the existing technology that uses belt scales and blending machines for traditional tea blending: 5 belt conveyors for feeding, weighing, and summarizing (20m x 5m x 5m) + 20m x 6m x 5m blending bins = 1100m 3 In this embodiment 1, an online assembly device for multi-head flow metering can save about 50% of space, that is, it occupies a smaller area, reducing equipment investment and space occupation.

[0034] With the rapid development of the new tea beverage industry, the market demand for health, wellness, ready-to-drink, environmental protection, and diverse flavors has driven the creation of the new tea beverage industry (compared to traditional tea production processes). In this embodiment 1, an online blending device with a multi-head flow metering combination can meet the blending needs of the new tea beverage industry. It can blend a large number of raw materials (up to 20 kinds of flower tea), a large ratio (e.g., 1:20, that is, the weight of the first material needs to be 1kg and the weight of the second material needs to be 20kg), a large output (e.g., 3 tons / hour), and high blending accuracy (i.e., the weight ratio error of various flower tea leaves is ±0.2%).

[0035] Specific embodiment 2: This embodiment 2 provides an online blending device with multiple flow metering combinations. The difference between this embodiment 2 and embodiment 1 is that in this embodiment 2, the second vibrating feeder 9 and the collecting chute 10 are not required between the chute 4-1 and the collecting belt conveyor 5. The material falling from the chute 4-1 of the combined scale 4 directly falls onto the collecting belt 5-1 of the collecting belt conveyor 5. The working principle of this online blending device with multiple flow metering combinations in embodiment 2 is as follows: After each feeding bin 1 is filled, the corresponding first feeding conveyor 2 transports various tea leaves to the corresponding first vibrating feeder 3. The corresponding first vibrating feeder 3, through vibration, transports the corresponding material to the corresponding section of the corresponding combined scale 4. Each combined scale 4 has four sections, which can weigh four types of materials. The combined scale 4 is equipped with a chute 4-1 (… Figure 4As shown, various tea leaves undergo initial blending as they fall through the chute 4-1 of the combined scale 4. They then fall onto the collection belt 5-1 of the collection conveyor 5, where different varieties of tea are stacked layer by layer, achieving a second blending effect. Next, they are conveyed by the second feeding conveyor 6 to the drum mixer 7 for further mixing, constituting a third blending. This process completes the accurate measurement and blending of multiple tea varieties. Finally, the blended tea is sent to the next production line for the next stage of production. The material undergoes three blending operations, resulting in high blending accuracy and uniform mixing.

[0036] This embodiment 2 presents an online blending device with a multi-head flow metering system. It utilizes several combined scales to accurately measure and blend various types of raw tea leaves for the first time, improving the accuracy of the blending ratio. A second blending is performed by directly feeding the leaves onto a conveyor belt and using several combined scales. Finally, a third blending is achieved by a drum mixer. The entire production process can be continuous and uninterrupted, increasing blending capacity. Compared to existing technologies that use conveyor belts and uniform stacking bins for secondary blending, this online blending device with a multi-head flow metering system adds an extra blending operation, improving the mixing uniformity of various raw tea leaves.
