Description

Technical Field

[0001] This invention relates to the field of tea beverage processing equipment technology, specifically to a feeding device for tea beverage ingredients. Background Technology

[0002] Health-preserving teas, as functional beverages that integrate traditional Chinese medicine wisdom with modern health concepts, use green tea, black tea, or oolong tea as a base, scientifically combining medicinal and edible ingredients—including dried petals of herbs such as chrysanthemum and rose, nourishing herbs like goji berries and astragalus, and dietary ingredients such as hawthorn and coix seed—to achieve targeted conditioning through precise formulations. Examples include an eye-protecting combination of Hangzhou white chrysanthemum and goji berries, a blood-nourishing formula with double-petaled roses and longan, and a dampness-removing formula with coix seed and lotus leaf, meeting modern people's core needs for convenient and functional health preservation. In industrial production, petals are typically fed using a vacuum feeding machine: a vacuum pump extracts air from the pipeline to create a negative pressure difference, drawing the petals from the storage silo into the conveying pipeline, ultimately delivering them to the mixing or packaging section.

[0003] However, in the process of using a vacuum feeder to transport flower petals, when the negative pressure airflow sucks the petals into the conveying pipe, the petals will collide and rub against the pipe wall, which will damage their morphological integrity and make them easily break into small pieces or powder, directly affecting the sensory quality and retention of effective ingredients of the finished tea beverage. Therefore, we propose a new type of feeding device for tea beverage ingredients. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a feeding device for tea beverage ingredients, which can effectively solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a feeding device for tea beverage ingredients, comprising a vacuum feeder body and a suction pipe fixedly installed thereon, wherein the suction pipe is provided with a structure to prevent petal breakage.

[0006] The anti-petal breakage structure includes several air inlet arc grooves formed on the inner circular surface of the suction pipe. A sliding sleeve adapted to the suction pipe is fixedly installed on the outer circular surface of the suction pipe. Several air inlet pipes penetrating the sliding sleeve are fixedly installed on the sliding sleeve. The air inlet pipes are connected to the inner cavity of the air inlet arc grooves.

[0031] This invention provides a technical solution:

[0032] Please see Figures 1-9 A feeding device for tea beverage ingredients includes a vacuum feeder body 1 and a suction pipe 2 fixedly installed thereon, and the suction pipe 2 is provided with a structure 3 to prevent petal breakage.

[0033] The anti-petal breakage structure 3 includes several air inlet arc grooves 301 formed on the inner circular surface of the suction pipe 2. A sliding sleeve 309 adapted to the suction pipe 2 is fixedly installed on the outer circular surface of the suction pipe 2. Several air inlet pipes 302 passing through the sliding sleeve 309 are fixedly installed on the sliding sleeve 309. The air inlet pipes 302 are connected to the inner cavity of the air inlet arc grooves 301. A hollow fan-shaped air cavity 303 is fixedly installed at the air outlet end of the air inlet pipes 302 on the same straight line. The middle section of the hollow fan-shaped air cavity 303 is fixedly... A split air duct 304 is fixedly installed, which communicates with the inner cavity of the hollow fan-shaped air cavity 303. A wind speed sensor 305 and an airflow control valve 306 are fixedly installed on the split air duct 304. A hollow main air ring 307 is fixedly installed at the air inlet end of the split air duct 304. An ion fan 308 is fixedly installed on the outside of the hollow fan-shaped air cavity 303. The air outlet duct of the ion fan 308 communicates with the inner cavity of the hollow main air ring 307. An air direction guide component 310 is provided in the inner cavity of the air inlet arc groove 301.

[0034] The working process of the anti-petal breakage structure 3 is as follows: The ion fan 308 generates airflow, which is distributed to each branch air duct 304 through the hollow main air ring 307. The wind speed sensor 305 monitors the wind speed in real time and adjusts it through the airflow control valve 306 to ensure uniform airflow in each branch. The airflow then enters the hollow fan-shaped air chamber 303, is guided into the air inlet arc groove 301 through the air inlet pipe 302, and finally is sprayed into the inner cavity of the suction pipe 2 at different angles through the air direction guide component 310, forming an annular air curtain barrier. Its function is to form a suspended air cushion on the inner wall of the pipe through controllable airflow, so that the petals are suspended in the center of the pipe during the transportation process, greatly reducing collision and friction with the pipe wall. At the same time, the ion wind neutralizes the static electricity of the petals and prevents them from sticking together. Combined with the air direction adjustment function, it adapts to the transportation needs of petals with different humidity, thereby effectively protecting the integrity of the petal shape, avoiding breakage, and improving the quality and production efficiency of tea beverage ingredients.

[0035] In some embodiments, the suction pipe 2 is inclined, the suction pipe 2 is made of stainless steel, and the suction pipe 2 is connected to the inner cavity of the vacuum feeder body 1.

[0036] In this embodiment, the inclined setting of the suction pipe 2 and the absence of a bent structure fundamentally avoid the impact damage problem that is prone to occur at the bending points of traditional pipes; its stainless steel material ensures that the pipe wall is smooth and wear-resistant, reducing the risk of petal adsorption and friction damage; and the connection design with the inner cavity of the vacuum feeder body 1 ensures the effective transmission of negative pressure suction, which is the structural basis for realizing stable, efficient and low-damage pneumatic conveying of petals.

[0037] In some embodiments, the lengths of the hollow fan-shaped air cavity 303 and the sliding sleeve 309 are less than the length of the suction pipe 2, the lengths of the hollow fan-shaped air cavity 303 and the sliding sleeve 309 are equal, and both the hollow fan-shaped air cavity 303 and the sliding sleeve 309 are located outside the vacuum feeder body 1.

[0038] In this embodiment, the hollow fan-shaped air chamber 303 and the sliding sleeve 309 are located outside the vacuum feeder body 1. Their length is shorter than that of the suction pipe 2, which ensures that the core air curtain generation function is concentrated in the key area of ​​the feeding section. This avoids a redundant structure and facilitates installation, debugging and maintenance. The equal length design of the two ensures the precise alignment and synchronous operation of all air inlet pipes 302 and air inlet arc grooves 301, which is the key structural guarantee for achieving a stable and uniform annular air curtain.

[0039] In some embodiments, a barrel-shaped filter screen 4 adapted to the suction pipe 2 is fixedly installed on the inner wall of the suction pipe 2; the inlet of the suction pipe 2 is symmetrically provided with electric telescopic rod mounting slots, a miniature electric telescopic rod 5 is fixedly installed in the inner cavity of the electric telescopic rod mounting slots, a linkage block 6 is fixedly installed at the output end of the miniature electric telescopic rod 5, and a linkage rod 7 fixedly connected to the sliding sleeve 309 is fixedly installed on the linkage block 6.

[0040] In this embodiment, the barrel-shaped filter screen 4 adheres to the inner wall of the suction pipe 2 during operation, directly intercepting the sucked-in petals and preventing them from entering and clogging the lower air inlet arc groove 301, thus ensuring smooth airflow. The miniature electric telescopic rod 5 drives the sliding sleeve 309 to move precisely along the axial direction of the suction pipe 2 through the linkage block 6 and the linkage rod 7, which is the direct power source for realizing the alignment switching of the air inlet pipe 302 between different air grooves (sloping upper / sloping lower trapezoidal air grooves).

[0041] In some embodiments, a plurality of air inlet arc grooves 301 are evenly distributed in a circumferential shape on the suction pipe 2, and a plurality of air inlet pipes 302 are evenly distributed in a circumferential shape on the sliding sleeve 309, with the air inlet arc grooves 301 and the air inlet pipes 302 corresponding one-to-one.

[0042] In this embodiment, the air inlet arc grooves 301 are evenly distributed around the inner wall of the suction pipe 2, and the air inlet pipes 302 are distributed on the sliding sleeve 309 in the same manner, with each pair precisely aligned. Their operation constitutes the final uniform distribution channel for airflow from the external air cavity into the interior of the pipe. This ensures that the airflow delivered from each air inlet pipe 302 can pass through the corresponding air inlet arc grooves 301 and be sprayed out synchronously and equally on the entire circumferential inner wall of the suction pipe 2, forming a continuous, stable, and uniformly thick annular air curtain. This provides all-round, dead-angle-free suspension support for the petals, preventing petal displacement and collision with the pipe wall due to uneven local airflow strength.

[0043] Please see Figure 8 and Figure 9 The wind direction guiding component 310 includes an upper hyperbolic triangular prism 3101 and a lower hyperbolic triangular prism 3102 fixedly installed on the inner wall of the air inlet arc groove 301. The upper hyperbolic triangular prism 3101 and the lower hyperbolic triangular prism 3102 form a vertical air inlet 3103 between the air inlet arc groove 301 and the air inlet arc groove 301.

[0044] The wind direction guiding component 310, through its unique geometric structure of an upward-sloping hyperbolic triangular prism 3101 and a downward-sloping hyperbolic triangular prism 3102, together forms a crucial vertical-axis air inlet 3103 within the inner cavity of the air inlet arc groove 301. Airflow from the air inlet duct 302 first enters this area, its flow path constrained and guided by the curved surfaces of the triangular prisms. Its core function is to act as a "dispatching station" for airflow direction, precisely converting the unidirectional airflow from the external air duct into vertical or specific-angle airflow according to delivery requirements, and ejecting it from the vertical-axis air inlet 3103. This provides the structural foundation and initial guidance for subsequent, more complex wind direction switching (such as upward or downward) within the upward / downward-sloping trapezoidal air duct, making it key to achieving multi-directional and controlled airflow.

[0045] Please see Figure 8 and Figure 9An inclined trapezoidal air duct 3014 is provided on the inclined upper hyperbola triangular prism 3101. An inclined lower wind baffle 3015 is provided on one side of the inclined lower trapezoidal air duct 3014 and is fixedly connected to the inclined upper hyperbola triangular prism 3101 and the air inlet arc groove 301. Several inclined lower air outlets 3016 are provided at the bottom of the inner cavity of the inclined lower trapezoidal air duct 3014.

[0046] The working process of the downward-sloping trapezoidal air duct 3014 is as follows: when the air inlet pipe 302 is aligned with it, the airflow enters and is constrained by the downward-sloping baffle 3015, and is concentrated and ejected from the downward-sloping air outlet 3016 at the bottom. This forms a clearly directed downward-sloping airflow, which is used to efficiently blow away residual impurities attached to the lower part of the barrel-shaped filter screen 4. It is a key active airflow outlet for realizing the self-cleaning function of the filter screen.

[0047] Please see Figure 8 and Figure 9 An upward trapezoidal air duct 3017 is provided on the downward hyperbola triangular prism 3102. An upward wind baffle 3018 is provided on one side of the upward trapezoidal air duct 3017 and is fixedly connected to the downward hyperbola triangular prism 3102 and the air inlet arc groove 301. Several upward air outlets 3019 are provided at the bottom of the inner cavity of the upward trapezoidal air duct 3017.

[0048] The working process of the upward-sloping trapezoidal air duct 3017 is as follows: When the sliding sleeve 309 moves to align the air inlet pipe 302 with the air duct, the airflow enters and is blocked and guided by the upward-sloping baffle 3018, and finally concentrated and ejected from the upward-sloping air outlet 3019 at the bottom. This forms a stable and concentrated upward-sloping airflow, which is mainly used to overcome the gravity of the petals during the conveying process, prevent them from accumulating at the bottom of the pipe, and propel them forward. At the same time, in self-cleaning mode, it is used to remove impurities from the upper part of the filter screen.

[0049] In practical use, the working principle of this invention is as follows:

[0050] When it is necessary to feed and convey dried flower petals into the ingredients of health-preserving tea, the suction pipe 2 is first placed above the petal holding device, and the device and ion fan 308 are started by the controller of the vacuum feeder body 1. The vacuum pump creates negative pressure in the suction pipe 2 to suck in the petals; at the same time, the ion fan 308 generates an electron-charged airflow to neutralize the static electricity generated by friction during the conveying process of the petals, preventing blockage or damage caused by static adsorption. The ion air first enters the hollow main air ring 307 and is then distributed through multiple branch air ducts 304. Since the hollow main air ring 307 has only one air inlet, uneven air velocity distribution is prone to occur. The wind speed sensor 305 installed on each branch air duct 304 monitors the wind speed in real time and feeds the data back to the controller. The controller adjusts the airflow control valve 306 accordingly to ensure that the air velocity of each branch is consistent, achieving uniform air delivery. After being split, the airflow enters the hollow fan-shaped air cavity 303, and then is transported to the air inlet arc groove 301 through the air inlet pipe 302. Finally, it is blown into the interior of the suction pipe 2 through the vertical shaft air inlet 3103, forming a ring-shaped gas isolation barrier on its inner wall.

[0051] When transporting dried petals, the miniature electric telescopic rod 5 remains fixed, and the airflow is blown vertically into the pipe, forming a stable air curtain. This allows the petals to be transported while suspended in the center of the pipe, greatly reducing collisions and friction with the pipe wall. If the petals are slightly damp, a mixed transport mode of "vertical wind as the main force and oblique upward wind as the auxiliary force" is adopted. For example, an oblique upward airflow is briefly sprayed for 0.3 seconds every 5 seconds, which can prevent the petals from accumulating at the bottom of the pipe and effectively propel them forward. At this time, the miniature electric telescopic rod 5 extends, so that the air inlet pipe 302 is located at the position of the obliquely downward hyperbolic triangular prism 3102. At this time, the air inlet pipe 302 is aligned with the obliquely upward trapezoidal air duct 3107, and the obliquely downward wind baffle 3105 can limit most of the airflow's spray range, forcing the airflow to be sprayed out from the obliquely upward air outlet 3109, forming an obliquely upward airflow and achieving rapid switching of wind direction. For damp petals, the main method is to transport them upwards at an angle. The inclined airflow helps to overcome the weight of the petals and peel them off the tube wall. At this time, the air inlet pipe 302 continuously sprays air into the inclined trapezoidal air duct 3107 and sprays it out under the guidance of the inclined air outlet 3109, forming an upward airflow.

[0052] During the suction process, the barrel-shaped filter 4 effectively prevents the petals from entering the air inlet arc groove 301, avoiding material jamming. Furthermore, the suction pipe 2 of this device adopts an inclined straight-line design without bends, fundamentally avoiding the impact damage problems that easily occur at the bends in traditional pipes. After feeding is completed, the petals are conveyed to the designated workstation. The vacuum feeder body 1 can be installed and used with a bracket according to actual needs.

[0053] When cleaning the impurities attached to the barrel-shaped filter screen 4 after the operation is completed, the ion fan 308 can be restarted and the miniature electric telescopic rod 5 can be controlled to extend and retract: first, the extension drives the sliding sleeve 309 to move downward, so that the air inlet pipe 302 is aligned with the upward trapezoidal air groove 3107, and the sprayed airflow moves obliquely upward along the pipe wall to remove impurities on the upper part of the filter screen; then the miniature electric telescopic rod 5 is retracted, so that the air inlet pipe 302 moves obliquely upward and is aligned with the downward trapezoidal air groove 3104, and the airflow changes to blowing downward obliquely to further clean the residual impurities at the bottom of the filter screen, thereby achieving efficient self-cleaning of the filter screen.

[0054] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
