Description

Technical Field

[0001] This invention relates to the technical field of tea processing, and in particular to the technical field of an intelligent tea conveying and uniform withering system. Background Technology

[0002] Withering is the first important step in tea production. Withering removes some of the moisture from freshly picked tea leaves, making them soft and easier to roll.

[0003] Currently, most tea processing uses sun withering, where fresh tea leaves are placed outdoors to be directly exposed to sunlight and air for several hours to achieve the purpose of processing tea. This traditional method of sun withering has disadvantages such as uneven withering, long withering time (around 6-18 hours), being greatly limited by climate conditions, high labor intensity, serious waste of fresh leaves, and most importantly, not meeting food hygiene requirements.

[0004] To address the problems mentioned above, for example, application number CN201220332191.8 discloses a tea withering machine. This utility model mainly consists of a housing of the tea withering machine, which contains a tea conveying mechanism and a heating device. A leaf inlet mechanism is located on one side of the housing, with a leaf inlet fan located below it. A leaf drifting chamber is located on the other side of the housing, connected to a leaf outlet trough. A leaf outlet hopper is located below the leaf outlet trough. The air conveying via the leaf inlet mechanism fan replaces the traditional chain-driven conveying method, which is environmentally friendly and hygienic; the tea withering efficiency is high; this utility model uses heating within the housing to achieve tea withering, resulting in good effect, guaranteed quality, improved efficiency, and reduced labor intensity for workers.

[0005] However, when using the above-mentioned device, the tea leaves need to be spread flat on the wire mesh plate inside the box. In order to ensure the effect, a large area needs to be spread, which takes up a lot of space. Due to the large size of the equipment, the hot air will decrease with the length of the air duct, affecting the withering effect of the tea leaves. Workers cannot guarantee that the tea leaves can be spread evenly, which will eventually lead to some areas not being withered enough and some areas being over-withered. After the withering process is completed, it is time-consuming and labor-intensive for workers to collect the tea leaves.

[0006] To address the problems mentioned above, for example, application number CN201921636823.8 discloses a tea withering machine, including a blower, an electric heating plate located to the right of the blower, and a control panel installed on one side of the blower. A feeding hopper frame is provided to the right of the electric heating plate, and a feeding hopper is installed above the feeding hopper frame. A conveyor belt fixed by a conveyor belt bracket is provided to the lower right of the feeding hopper. The conveyor belt has several layers from top to bottom, and a guide plate is provided between every two layers. It changes from a single-layer steel wire mesh plate in the prior art to a three-layer conveyor belt, which greatly reduces the space occupied. Due to the shortened length, the blowing and heating effects of the blower and the electric heating plate are enhanced, making the tea more evenly heated and ensuring the withering effect. A uniform feed claw is installed on the feeding side above the conveyor belt each time, which can ensure that the tea leaves passing through the uniform feed claw have a uniform thickness.

[0007] However, the above-mentioned device still has the following drawbacks: Although the above-mentioned device spreads the tea leaves evenly on the conveyor belt using a uniform gripper, the tea leaves do not move after being spread on the conveyor belt. As a result, the upper and lower layers of tea leaves cannot be heated evenly during the withering process, leading to different withering effects between the upper and lower layers, thus affecting the processing results. Summary of the Invention

[0008] The purpose of this invention is to solve the problems in the prior art and propose an intelligent tea conveying and uniform withering system that can continuously turn the tea leaves during the withering process through the reciprocating motion of the frame, thereby improving the withering effect.

[0009] To achieve the above objectives, this invention proposes an intelligent tea conveying and uniform withering system, comprising a support frame, a conveyor belt, a horizontal plate, a feed hopper, a base frame, a workbench, a frame, a drive mechanism, concave supports, a blower, horizontal supports, electric heating rods, and a control panel. The support frame has a conveyor belt above it, a horizontal plate on one side of the support frame, and a feed hopper mounted on the horizontal plate at the feed end of the conveyor belt. The base frame is connected below the support frame, and a workbench is connected above the base frame. A frame is mounted on the workbench at the discharge end of the conveyor belt, and a drive mechanism is located below the base frame. Two concave supports are located above the base frame, and a blower is connected between the two concave supports. Horizontal supports are located below each concave support, and several electric heating rods are horizontally distributed between the two horizontal supports. A control panel is mounted on the side wall of the support frame, and the control panel is electrically connected to the blower and the electric heating rods.

[0010] Preferably, the drive mechanism includes a drive motor, a first flywheel, a support plate, a bearing housing, a drive shaft, a second flywheel, a drive belt, and an eccentric wheel. The drive motor is bolted to the base frame, and the input end of the drive motor is electrically connected to the control panel. The first flywheel is fixedly mounted on the output shaft of the drive motor. An opening is provided on the worktable, and a support plate is installed in the opening. One bearing housing is installed on the support plate and on the worktable, respectively. A drive shaft rotates between the two bearing housings, and a second flywheel is fixedly mounted on the drive shaft. A drive belt is sleeved on the outside of the second flywheel and the first flywheel. One end of the drive shaft passes through the side wall of one of the bearing housings and is connected to an eccentric wheel.

[0011] Preferably, two fixing seats are installed on the side wall of the frame, a crossbar is fixed between the two fixing seats, a connecting rod is installed on the crossbar, and the other end of the connecting rod is installed on the eccentric wheel.

[0012] Preferably, the frame is made of a high-temperature resistant material, and the frame has several through holes arranged in an equally spaced array.

[0013] Preferably, the workbench is equipped with two sets of slide rails, which are distributed parallel to each other along the length of the workbench. Each set of slide rails has two sliders slidably connected to it, and the upper end face of each slider is fixedly connected to the lower end face of the frame.

[0014] Preferably, the electric heating rod is located at the air outlet of the blower, and the electric heating rod is vertically aligned with the frame.

[0015] Preferably, baffles are installed on both sides of the conveyor belt, and the baffles are horizontally distributed along the length of the conveyor belt.

[0016] Preferably, air guide plates are installed on both sides of the air outlet of the blower, and the air guide plates are arranged to expand slightly outward.

[0017] The beneficial effects of this invention are: 1. This invention uses a drive mechanism to move the frame back and forth on the workbench, causing the tea leaves to turn over continuously during the withering process. This breaks the static state of the tea leaves lying flat on the conveyor belt, thereby ensuring that both the upper and lower layers of tea leaves are exposed to hot air, avoiding the problem of insufficient heating of the lower layer of tea leaves or overheating of the upper layer of tea leaves. 2. This invention provides uniform hot air through a blower and an electric heating rod, and ensures uniform hot air distribution and coverage of the entire tea leaf layer through through holes and air guides. The control panel allows for precise control of withering conditions, such as temperature, wind speed and vibration frequency, further ensuring consistent withering results.

Detailed Implementation

[0019] See Figures 1 to 7This invention discloses an intelligent tea conveying and uniform withering system, comprising a support frame 1, a conveyor belt 2, a horizontal plate 3, a feed hopper 4, a base frame 5, a workbench 6, a frame 7, a drive mechanism 8, concave supports 9, a blower 10, a horizontal support 11, an electric heating rod 12, and a control panel 13. The conveyor belt 2 is positioned above the support frame 1, and a horizontal plate 3 is positioned on one side of the support frame 1. A feed hopper 4 is mounted on the horizontal plate 3, located at the feed end of the conveyor belt 2. The base frame 5 is connected below the support frame 1, and the workbench 6 is connected above the base frame 5. A frame 7 is positioned on the workbench 6, located at the discharge end of the conveyor belt 2. The drive mechanism 8 is positioned below the base frame 5. Two concave supports 9 are positioned above the base frame 5. A blower 10 is connected above the concave support 9. A horizontal support 11 is provided below each of the concave support 9. Several electric heating rods 12 are horizontally distributed between two horizontal supports 11. A control panel 13 is installed on the side wall of the support 1. The control panel 13 is electrically connected to the blower 10 and the electric heating rods 12. First, the tea leaves fall from the feed hopper 4 onto the conveyor belt 2. The conveyor belt 2 continuously transports the tea leaves to the frame 7. The blower 10 and the electric heating rods 12 work together to generate hot air to heat and wither the tea leaves. The control panel 13 is electrically connected to the blower 10 and the electric heating rods 12, allowing the user to adjust the wind speed and temperature to control the withering process. At the same time, the conveyor belt 2 is driven by an external motor (not shown in the figure). The start, stop and speed of the motor are controlled by the control panel 13.

[0020] See Figure 2The drive mechanism 8 includes a drive motor 801, a first flywheel 802, a support plate 803, a bearing seat 804, a transmission shaft 805, a second flywheel 806, a transmission belt 807, and an eccentric pulley 808. The drive motor 801 is bolted to the base frame 5. The input end of the drive motor 801 is electrically connected to the control panel 13. The first flywheel 802 is fixedly mounted on the output shaft of the drive motor 801. An opening 14 is provided on the worktable 6, and the support plate 803 is installed in the opening 14. One bearing seat 804 is installed on the support plate 803 and the worktable 6, respectively. A transmission shaft 805 rotates between the two bearing seats 804. The first flywheel 806 is fixedly mounted on the transmission shaft 807. Two flywheels 806 are connected to each other by a transmission belt 807. One end of the transmission shaft 805 passes through the side wall of one of the bearing seats 804 and is connected to an eccentric wheel 808. The drive motor 801 is started by the control panel 13. The drive motor 801 drives the output shaft to rotate and drives the first flywheel 802 to rotate. After the first flywheel 802 rotates, it drives the second flywheel 806 to rotate through the transmission belt 807. After the second flywheel 806 rotates, it drives the transmission shaft 805 to rotate on the bearing seat 804. After the transmission shaft 805 rotates, it drives the eccentric wheel 808 to generate eccentric motion, and then transmits the motion to the subsequent components, and finally drives the frame 7 to vibrate.

[0021] See Figure 3 Two fixed seats 15 are installed on the side wall of the frame 7, and a crossbar 16 is fixed between the two fixed seats 15. A connecting rod 17 is installed on the crossbar 16, and the other end of the connecting rod 17 is installed on the eccentric wheel 808. When the eccentric wheel 808 rotates, the frame 7 is driven to make horizontal reciprocating motion through the connecting rod 17 and the crossbar 16. The fixed seats 15 and the crossbar 16 provide a stable connection, so that the vibration of the frame 7 is synchronized with the eccentric wheel 808, thereby turning the tea leaves.

[0022] See Figure 2 The frame 7 is made of high-temperature resistant material and has several through holes 18. The through holes 18 are arranged in an equally spaced array. Hot air is blown from the blower 10 and the electric heating rod 12 and blown onto the tea leaves through the through holes 18 on the frame 7. The equally spaced through holes 18 ensure that the hot air covers the entire surface of the tea leaves. At the same time, the tea leaves are turned over by vibration, so that the upper and lower layers of tea leaves can be heated. In addition, the through holes 18 have a microporous structure, which ensures that air can pass through without leakage. The frame 7 is made of high-temperature resistant material, which is not easily melted by high temperature and extends its service life.

[0023] See Figure 4The worktable 6 is equipped with two sets of slide rails 19, which are distributed parallel to each other along the length of the worktable 6. Each set of slide rails 19 is slidably connected to two sliders 20. The upper end face of each slider 20 is fixedly connected to the lower end face of the frame 7. The frame 7 is connected to the slide rails 19 through the sliders 20. When the drive mechanism 8 drives the frame 7 to vibrate, the slide rails 19 guide the frame 7 to make linear reciprocating motion along the length of the worktable 6, so as to avoid the frame 7 from shifting or getting stuck, and ensure stability during the vibration process.

[0024] See Figure 5 The electric heating rod 12 is located at the air outlet of the blower 10, and the electric heating rod 12 is vertically aligned with the frame 7. When the air blown out by the blower 10 passes through the electric heating rod 12, it is heated to form a hot air flow. The hot air flow blows directly onto the frame 7. The electric heating rod 12 is vertically aligned with the frame 7, so that the tea leaves can fully contact the hot air during vibration, achieving a uniform withering effect.

[0025] See Figure 6 The conveyor belt 2 is equipped with baffles 21 on both sides. The baffles 21 are horizontally distributed along the length of the conveyor belt 2 and are installed along both sides of the conveyor belt 2 to form a guardrail structure. When the tea leaves are transported on the conveyor belt 2, they are confined between the baffles 21 and are smoothly transported to the frame to avoid scattering.

[0026] See Figure 5 The blower 10 has air guide plates 22 installed on both sides of the air outlet end. The air guide plates 22 are slightly expanded outward. When hot air is blown out, the air guide plates 22 guide the airflow to a wider area, so that the hot air is evenly distributed to the whole frame 7, improving the withering uniformity.

[0027] Working process of this invention: In the operation of this intelligent tea conveying and uniform withering system, tea leaves first fall from the feed hopper 4 onto the conveyor belt 2, which smoothly transports the tea leaves into the frame 7. Then, the drive motor 801 is activated via the control panel 13. The drive motor 801 drives the output shaft to rotate, which in turn drives the first flywheel 802 to rotate. The rotation of the first flywheel 802, via the transmission belt 807, drives the second flywheel 806 to rotate. The rotation of the second flywheel 806 then drives the transmission shaft 805 to rotate on the bearing seat 804. The rotation of the transmission shaft 805 then drives the eccentric wheel 808 to produce eccentric motion. When the eccentric wheel 808 rotates, it drives the frame 7 to perform horizontal reciprocating motion via the connecting rod 17 and the crossbar 16. The slider 20 below the frame 7 slides on the slide rail 19, causing the tea leaves to tumble continuously inside the frame 7. At the same time, the air blown by the blower 10 is heated by the electric heating rod 12 to form hot air, which is evenly blown onto the frame 7 through the air guide plate 22. The through holes 18 on the frame 7 allow the hot air to penetrate the tea leaf layer, heating the upper and lower layers of tea leaves simultaneously. The control panel 13 controls the operating parameters of the drive motor 801, blower 10, and electric heating rod 121, adjusting the vibration frequency, wind speed, and temperature to achieve intelligent withering. The baffle plate 21 ensures that the tea leaves do not scatter during the conveying process. The entire process ensures that the tea leaves are heated evenly during withering, improving the processing quality. After withering is completed, the staff can then remove the tea leaves from the frame 7.

[0028] The control method of this invention is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this invention is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.
