Description

Technical Field

[0001] The invention belongs to the technical field of tea processing, and in particular relates to a tea roller stacking machine and a stacking method thereof. Background Art

[0002] The tea drum stacking machine is mainly used to further mix and stack the tea leaves that have been preliminarily processed. The key to this process is to ensure the consistency and quality control of the final tea product. The tea leaves are physically tumbled in the drum so that tea leaves of different types and qualities can be fully mixed. By adjusting the rotation speed and processing time, the uniformity of mixing and the efficiency of processing can be controlled. The existing tea drum stacking machines have problems of uneven mixing and low mixing efficiency. Chinese patent CN115644267A discloses a tea production equipment, in which a stirring shaft is rotatably arranged on the central axis of the drum, a stirring sleeve is fixedly connected to the surface of the stirring shaft, and an arc-shaped stirring blade is fixedly arranged on the surface circumference of the stirring sleeve. The inner wall of the drum is fixedly connected to a plurality of inclined plates, and the tea leaves are stacked evenly by the arrangement of stirring blades and inclined plates.

[0003] However, in the above invention, the stirring device for mixing tea leaves is relatively simple and has limited mixing capacity. It takes a long time to mix, which affects the mixing efficiency. The setting of the inclined plate affects the final unloading and the tea leaves are easily stuck at the connection between the inclined plate and the inner wall of the cylinder, causing material loss. Summary of the invention

[0004] The purpose of the present invention is to provide a tea drum stacking machine and a stacking method thereof in view of the above-mentioned technical problems, so as to achieve the effects of high mixing efficiency and convenient unloading.

[0005] In view of this, the present invention provides a tea roller stacking machine and a stacking method thereof, comprising a conveying device, wherein the conveying device transports materials into the stacking device, the stacking device comprises a roller rotatably mounted on a base, the roller is connected to a driving unit, a mixing structure is arranged in the drum, and the mixing structure comprises: a first mixing unit, the first mixing unit comprises a fixed rod arranged along the midline and fixedly connected to the side wall of the roller, and mixing plates are staggered on both sides of the fixed rod; a turning plate, wherein a plurality of turning plates are fixedly connected to the inner wall of the roller, and during the rotation of the roller, the turning plates can drive the bottom material to a higher place to ensure that the material is fully mixed; a material guiding structure, wherein the material guiding structure is fixedly connected to the inner wall of the roller, and during the unloading process, the material guiding structure can guide the tea leaves to the material inlet and outlet.

[0006] In this technical solution, the first mixing unit, the turning plate, and the material guiding structure cooperate with each other during the tea mixing process and jointly participate in the mixing, resulting in a better mixing effect. The above structures can fully mix the tea that occupies up to 70% of the inner cavity volume of the drum. Generally, when the tea in the drum exceeds 50%, during unloading, the turning plate and the material guiding structure can cooperate with each other to guide the well-mixed tea in the drum to the inlet and outlet, enabling efficient and uniform discharging, and ensuring the quality and efficiency of tea blending.

[0007] In the above technical solution, further, a connecting plate is radially connected to the middle of the fixed rod. The connecting plates are symmetrically arranged, and the other end of the connecting plate extends and is connected to the inner wall of the drum. The connecting plate is connected with several mixing plates that extend and are connected to the side walls of the drum on both sides respectively. The mixing plates on both sides are staggered to form a mixing channel for the tea to pass through.

[0008] In this technical solution, during the rotation of the drum, the mixing plates mix the tea, driving the tea to move and mix in the drum through the mixing channel, and fully mixing the tea in the drum.

[0009] In the above technical solution, further, the turning plate is a "V"-shaped plate body, and the side of the turning plate is fixedly connected to the inner wall of the drum.

[0010] In this technical solution, in this embodiment, the number of turning plates is three, which are circumferentially arranged on the inner wall of the drum, and the open direction faces the inlet and outlet. When the drum rotates, the "V"-shaped turning plate can bring the tea at the bottom to a high place and let it fall, which can fully mix the tea in the drum and avoid the problem of uneven mixing caused by too much tea.

[0011] In the above technical solution, further, the material guiding structure includes a collecting plate. The collecting plate is a "C"-shaped plate body, which is arranged at the inlet and outlet. The open direction of the collecting plate is opposite to that of the turning plate. Symmetrically connected to both sides of the collecting plate are material guiding plates that are inclined towards the inlet and outlet.

[0012] In this technical solution, the side of the material guiding plate is in contact with and fixedly connected to the inner wall of the drum, preferably a plate body that is spirally inclined towards the inlet and outlet. The material guiding plate can participate in the tea mixing and improve the tea mixing efficiency. During the unloading process after mixing, it cooperates with the collecting plate to fully guide the tea to leave the drum from the inlet and outlet, improving the unloading efficiency.

[0013] In the above technical solution, further, one end of the material guiding plate is connected to the collecting plate, and the other end extends towards the side wall of the drum and is connected to a side baffle arranged on the side wall of the drum. The side baffle is arranged along the radial direction of the drum. One end of the side baffle is connected to the fixed rod, and the other end extends towards the inner wall of the drum and is connected. And the end of the side baffle far from the fixed rod is connected to the material guiding plate.

[0014] In this technical solution, the side baffles and guide plates can participate in tea mixing and improve the tea mixing efficiency. They can also fully guide the tea to leave the drum from the inlet and outlet during the unloading process after mixing, thereby improving the unloading efficiency.

[0015] In the above technical solution, further, collecting plates are symmetrically arranged on both sides of the drum and are inclined along the surface of the drum toward the bottom of the drum, and material protection plates are arranged on both sides of the collecting plates.

[0016] In this technical solution, the collecting plate and the base are fixedly connected by supporting bars. After the tea leaves inside the drum are evenly mixed, the rotation speed of the drum is slowed down, and the closed doors at the three material inlets and outlets are opened. Following the rotation of the drum, the evenly mixed tea leaves fall out from the inner cavity of the drum through the material inlets and outlets. The setting of the collecting plate can fully guide the tea leaves to gather at the bottom of the drum. A conveyor belt (not shown) can be set at the bottom of the drum for transmission, so as to achieve automatic, stable and uniform material discharging.

[0017] In the above technical scheme, further, a closing door capable of closing the material inlet and outlet is provided at the material inlet and outlet, the closing door is slidably arranged in a support frame, the support frame and the roller are fixedly connected, a first rack is fixedly arranged on the top of the closing door, the rack is meshed with a first gear, the first gear is coaxially fixedly connected to a driving rod, the driving rod is rotatably arranged on the first supporting seats on both sides, one end of the driving rod passes through the supporting seat and is transmission-connected to a third motor, the third motor is connected to the surface of the roller through the second supporting seat, touch plates extend from both sides of the closing door, first fixed plates are provided on both sides of the support frame corresponding to the touch plates, a pressure sensor is provided on the first fixed plate, the pressure sensor is connected to a pressure contact, and one side of the pressure contact can abut against the touch plate when the closing door is opened or closed.

[0018] In the present technical scheme, three material inlets and outlets are arranged on the circumference of the drum, and the material inlets and outlets are not limited to three, and all of them are provided with closing doors capable of closing the material inlets and outlets. When feeding, one material inlet and outlet is directed upward to feed the material to the material inlet and outlet. After the feeding is completed, all the material inlets and outlets are closed, and the drum is started to mix the internal tea leaves. When discharging the material, the closing doors at all the material inlets and outlets are opened, and the evenly mixed tea leaves fall out of the inner cavity of the drum through the material inlet and outlet as the drum rotates, and the material is unloaded quickly. A conductive slip ring is arranged on one side of the motor of the drum, which can solve the problem of routing the motor power cord and prevent entanglement. The arrangement of the pressure sensor, the pressure contact and the touch plate can provide feedback on whether the closing door is fully opened or closed. At the same time, through the arrangement of the third motor, the driving rod, the rack and the gear, the operator is no longer required to manually close the closing door, thus avoiding the inconvenience of manually opening and closing the closing door and improving production efficiency.

[0019] In the above technical solution, it further includes a mixing box, which is installed below the discharge port. The mixing box is provided with a feeding channel for tea leaves to pass through, and the feeding channel is provided with a mixing assembly, which can change the falling position of the tea leaves leaving the mixing box.

[0020] In the above technical solution, further, the material leveling assembly is a plurality of material drop baffles rotatably arranged in the material discharge channel, any of the material drop baffles is transmission-connected to a driving motor, and the plurality of material drop baffles in the material discharge channel are arranged in decreasing vertical heights in the direction away from the discharge port.

[0021] In this technical solution, in this embodiment, four blanking baffles are rotatably arranged, and a rotating rod is arranged in the middle of each blanking baffle, and the rotating rod is rotatably connected to the inside of the blanking channel, and a driving motor is fixedly arranged on the outer side of the material screed box, and the output end of the driving motor passes through the material screed box and is coaxially connected to the rotating rod. The driving motor drives the rotating rod to rotate to control the angular position of the blanking baffle. Figure 7 As shown, each drop baffle is inclined away from the discharge port, and the tea leaves poured from the discharge port can fall along the drop baffle from the leftmost side into the feed inlet and outlet of the roller below. Figure 8 As shown, the drop baffle directly below the discharge port is adjusted to a vertical angle, so that the tea leaves poured from the discharge port can fall vertically. In addition, by rotating other drop baffles, the specific implementation method of making the tea leaves fall from different positions is not repeated. The material leveling component is set in this way to ensure the continuity of feeding, avoid continuous feeding at a single point, which will cause the tea leaves to form a "mountain" shape, affecting the feeding of tea leaves. It is necessary to temporarily close the closed door of the feed inlet and outlet, rotate the drum, and evenly distribute the tea leaves in the drum, and then open the closed door again to continue feeding, which affects the feeding efficiency and the overall tea pile-leveling efficiency.

[0022] The invention also comprises a method for stacking tea leaves using the above tea drum stacking machine, comprising the following steps:

[0023] S1: confirm that any inlet and outlet of the drum is facing upward, start the third motor, open the closed door with the inlet and outlet facing upward, start the conveying device and the screed assembly in the screed box, and transport the tea leaves to the screed box arranged above the inlet and outlet;

[0024] S2: The material-splitting component adjusts the falling position of the tea leaves by adjusting the angles of several falling baffles in the falling channel, so that the tea leaves fall evenly into the drum. The tea leaves in the drum do not exceed 70% of the internal volume of the drum. After the material feeding is completed, the closing door at the top inlet and outlet is closed;

[0025] S3: Start the material mixing device, the driving unit drives the drum to rotate, and the mixing structure inside the drum mixes the materials;

[0026] S4: The drum rotates for 10 to 60 minutes. After sufficient mixing, the drum speed is slowed down, and all closed doors are opened for unloading. The tea leaves leave the drum from the inlet and outlet and are collected along the collecting plate.

[0027] The beneficial effects of the present invention are:

[0028] 1 The first mixing unit, the turning plate and the material guiding structure cooperate with each other during the tea mixing process and participate in the mixing together, so as to achieve a better mixing effect. The above-mentioned structure can fully mix the tea that occupies up to 70% of the volume of the drum cavity in the drum. When the tea exceeds 50%, the stacking effect of the general drum stacking machine is significantly reduced. When unloading, the turning plate and the material guiding structure can cooperate with each other to guide the fully mixed tea in the drum to the inlet and outlet, so as to discharge the tea efficiently and evenly, and ensure the quality and efficiency of tea stacking;

[0029] 2. When discharging, open the closed doors at all the inlet and outlet ports, follow the rotation of the drum, and the evenly mixed tea leaves fall out from the inner cavity of the drum through the inlet and outlet ports for quick unloading. The drum is provided with a conductive slip ring on one side of the motor, which can solve the problem of the motor power line routing and will not be entangled. The settings of the pressure sensor, pressure contact and touch plate can provide feedback on whether the closed door is fully opened or closed. At the same time, through the settings of the third motor, drive rod, rack and gear, the operator is no longer required to manually close the closed door, avoiding the inconvenience of manual opening and closing of the closed door, and improving production efficiency;

[0030] 3. Setting a material mixing box and a material mixing component in the feeding channel of the material mixing box can ensure the continuity of feeding and avoid continuous feeding at a single point, which will cause the input tea to form a "mountain" shape and affect the feeding of tea. It is necessary to temporarily close the closing door of the feeding port, rotate the drum, and evenly distribute the tea in the drum. Then, open the closing door again and continue feeding, which affects the feeding efficiency and the overall tea stacking efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] First embodiment:

[0047] like Figure 1-6As shown, the present embodiment provides a tea roller stacking machine and a stacking method thereof, including a conveying device 1, wherein the conveying device 1 transports materials into the stacking device 7, the stacking device 7 includes a roller 71 rotatably mounted on a base 3, the roller 71 is connected to a driving unit 2, a mixing structure is arranged in the roller 71, and the mixing structure includes: a first mixing unit 73, the first mixing unit 73 includes a fixed rod 731 arranged along the midline and fixedly connected to the side wall of the roller 71, and mixing plates 732 are staggered on both sides of the fixed rod 731; a turning plate 74, wherein a plurality of turning plates 74 are fixedly connected to the inner wall of the roller 71, and during the rotation of the roller 71, the turning plates 74 can drive the bottom material to a higher place to ensure that the material is fully mixed; a material guiding structure 75, wherein the material guiding structure 75 is fixedly connected to the inner wall of the roller 71, and during the unloading process, the material guiding structure 75 can guide the tea leaves to the inlet and outlet 72.

[0048] The curved wall of the drum 71 is called the inner wall, and the circular walls on both sides are called the side walls. The first mixing unit 73, the turning plate 74 and the material guiding structure 75 cooperate with each other in the tea mixing process and participate in the mixing together, so the mixing effect is better. The above-mentioned structural cooperation can fully mix the tea leaves in the drum 71 that occupy up to 70% of the volume of the inner cavity of the drum 71. Generally, the mixing efficiency of the drum 71 stacking machine decreases significantly when the tea leaves exceed 50%. When unloading, the turning plate 74 and the material guiding structure 75 can cooperate with each other to guide the fully mixed tea leaves in the drum 71 to the inlet and outlet 72, so as to discharge the materials efficiently and evenly, thereby ensuring the quality and efficiency of tea stacking.

The other end of the connecting plate 733 extends and is connected to the inner wall of the drum 71. The connecting plate 733 is connected to a plurality of mixing plates 732 that extend and are connected to the side walls of the drum 71 on both sides, and the mixing plates 732 on both sides are staggered to form a mixing channel 734 for tea leaves to pass through. During the rotation of the drum 71, the mixing plates 732 mix the tea leaves, driving the tea leaves to move and mix in the drum 71 through the mixing channel 734, and fully mixing the tea leaves in the drum 71.

[0050] like Figure 2 and Figure 3 As shown, the turning plate 74 is a "V"-shaped plate, and the side of the turning plate 74 is fixedly connected to the inner wall of the drum 71. In this embodiment, there are three turning plates 74, which are arranged on the inner wall of the drum 71 in a circle, and the opening direction faces the inlet and outlet 72. When the drum 71 rotates, the "V"-shaped turning plate 74 can bring the tea leaves at the bottom to a high place and fall down, so that the tea leaves in the drum 71 can be fully mixed, avoiding the problem of uneven mixing caused by too much tea leaves.

Preferably, it is a plate body that is spirally inclined towards the feeding and discharging opening 72. The material guiding plate 752 can participate in the tea mixing, improving the tea mixing efficiency. During the discharging process after mixing, in cooperation with the collecting plate 751, it can fully guide the tea to leave the roller 71 from the feeding and discharging opening 72, improving the discharging efficiency.

[0052] One end of the material guiding plate 752 is connected to the collecting plate 751, and the other end extends towards the side wall of the roller 71 and is connected to a side baffle 753 arranged on the side wall of the roller 71. The side baffle 753 is arranged along the radial direction of the roller 71. One end of the side baffle 753 is connected to the fixed rod 731, and the other end extends towards the inner wall of the roller 71 and is connected. Moreover, the end of the side baffle 753 far from the fixed rod 731 is connected to the material guiding plate 752.

[0053] The settings of the side baffle 753 and the material guiding plate 752 can participate in the tea mixing, improving the tea mixing efficiency, and can also fully guide the tea to leave the roller 71 from the feeding and discharging opening 72 during the discharging process after mixing, improving the discharging efficiency.

[0054] As Figure 4 and Figure 5 shown in Figure 4 and Figure 5 , on both sides of the roller 71, there are symmetrically arranged collecting plates 9 that are inclined from the surface of the roller 71 towards the bottom of the roller 71. On both sides of the collecting plates 9, there are guard plates 10.

[0055] The collecting plates 9 and the base 3 are fixedly connected through support bars 11. After the tea inside the roller 71 is evenly mixed, the rotation speed of the roller 71 is slowed down, and the closing doors 12 at the three feeding and discharging openings 72 are opened. Following the rotation of the roller 71, the evenly mixed tea falls out from the inner cavity of the roller 71 through the feeding and discharging openings 72. The setting of the collecting plates 9 can fully guide the tea to converge towards the bottom of the roller 71. A conveyor belt (not shown) can be arranged at the bottom of the roller 71 for transmission, achieving automatic, stable, and uniform discharging.

[0057] The drum 71 is provided with three material inlet and outlet ports 72 on its circumference, and the material inlet and outlet ports 72 are not limited to three. All of them are provided with a closing door 12 capable of closing the material inlet and outlet ports 72. When feeding, one material inlet and outlet port 72 is directed upward to feed the material to the material inlet and outlet port 72. After the feeding is completed, all the material inlet and outlet ports 72 are closed, and the drum 71 is started to mix the internal tea leaves. When discharging, the closing doors 12 at all the material inlet and outlet ports 72 are opened, and the drum 71 rotates, and the evenly mixed tea leaves fall out from the inner cavity of the drum 71 through the material inlet and outlet ports 72 for rapid unloading. The drum 71 is provided with a conductive slip ring on one side of the motor, which can solve the problem of routing the motor power line without entanglement.

[0058] Second embodiment:

[0059] This embodiment provides a tea leaf roller stacking machine and a stacking method thereof, which, in addition to the technical solutions of the above-mentioned embodiments, also have the following technical features.

[0060] like Figure 1 , Figure 7 and Figure 8 As shown, it also includes a material mixing box 4, which is mounted on the top of the roller. A material discharge channel 5 for tea leaves to pass through is arranged in the material mixing box 4, and a material mixing component 6 is arranged in the material discharge channel 5. The material mixing component 6 can change the falling position of the tea leaves leaving the material mixing box 4.

[0061] The material leveling assembly 6 is a plurality of material drop baffles 61 rotatably arranged in the material drop channel 5 . Any of the material drop baffles 61 is transmission-connected to a driving motor. The plurality of material drop baffles 61 in the material drop channel 5 are arranged in decreasing vertical heights away from the discharge port 24 .

[0062] In this embodiment, four blanking baffles 61 are rotatably arranged, and a rotating rod 62 is arranged in the middle of each blanking baffle 61. The rotating rod 62 is rotatably connected to the inside of the blanking channel. A driving motor is fixedly arranged on the outer side of the material screed box 4. The output end of the driving motor passes through the material screed box 4 and is coaxially connected to the rotating rod 62. The driving motor drives the rotating rod 62 to rotate to control the angular position of the blanking baffle 61. Figure 7 As shown, each of the drop baffles 61 is inclined away from the discharge port 24, and the tea leaves poured from the discharge port 24 can fall along the drop baffles 61 from the leftmost side into the feed inlet and outlet 72 provided in the lower drum 71, as shown in FIG. Figure 8 As shown, the drop baffle 61 directly below the discharge port 24 is adjusted to a vertical angle, so that the tea leaves poured from the discharge port 24 can fall vertically. In addition, by rotating other drop baffles 61, the specific implementation method of making the tea leaves fall from different positions is not repeated.
