Description

Technical Field

[0001] This invention relates to the field of tea production equipment technology, specifically to a tea loosening machine and loosening method for vine tea. Background Technology

[0002] Vine tea is characterized by its long length and good toughness, which greatly differs from the shape of ordinary tea leaves. This length and toughness make vine tea prone to tangling and clumping during typical processing steps such as fixing, rolling, and crystallization, affecting subsequent production and product quality. Therefore, vine tea requires a special untangling process (to separate the tangled vine tea leaves). However, unlike the dispersion of ordinary tea leaves, dispersing vine tea is very difficult, and ordinary tea untangling machines cannot meet the requirements. Therefore, a special untangling machine needs to be developed specifically for vine tea to solve its clumping and tangling problems. Furthermore, since the untangling process is usually intermittent, vine tea leaves on continuous production lines are easily cooled during movement, which also affects the quality of the vine tea. Chinese patent document CN220123874U, published on December 5, 2023, discloses a bag-loosening machine, including a bag-loosening machine body. The body is horizontally arranged with a drive assembly at the right end. The opening of the body faces left. The drive end of the drive assembly is located inside the body. A noise-reducing mechanism is located outside the body, including a soundproof cover, connecting blocks, an exhaust assembly, and a cover assembly. Both the upper and lower ends of the body are connected to the inner wall of the soundproof cover via connecting blocks. The inner wall of the cover has a soundproof assembly. Multiple exhaust assemblies are located on the right end of the cover, which opens to the left. This bag-loosening machine, through its noise-reducing mechanism, can reduce noise when it produces noise, preventing disturbance to the operator and the surrounding environment. However, this machine is specifically designed to address noise issues during operation and is not suitable for loosening rattan tea. Summary of the Invention

[0003] The purpose of this invention is to solve the problem that vine tea is prone to clumping and tangling during processing, and that loosening the vine tea bundles is very difficult. This invention provides a vine tea loosening machine with the advantages of simple structure, good loosening effect, and the ability to meet the requirements of continuous production.

[0004] The technical solution adopted by the present invention to solve the above-mentioned technical problems is a rattan tea loosening machine, including a frame, a loosening roller on the frame, a feeding section and a discharging section at both ends of the loosening roller, a feeding spiral guide rib and a discharging spiral guide rib respectively on the inner wall of the feeding section and the discharging section, a number of rows of axially arranged loosening teeth on the inner wall of the middle section of the loosening roller, the loosening teeth being offset on the circumferential surface of the inner wall of the loosening roller, and a heating device on the outer circumference of the loosening roller. The loosening roller of this invention has loosening teeth on the inner wall of the middle section. As the roller rotates, these teeth disperse the rattan tea. Simultaneously, as the rattan tea is pulled upwards by the loosening teeth, some of the tea not directly pulled will fall downwards, thus achieving a dispersion effect. Furthermore, the loosening teeth of this invention are offset rather than uniformly distributed along the circumference of the loosening roller; at least half of the roller's arc surface is smooth. This ensures that when the rattan tea is dropped from a high point, it is not obstructed by the loosening teeth, allowing for more stretching space as it falls under gravity. Practice has shown that this is more conducive to the dispersion of the rattan tea, thereby solving the problem of the difficulty in loosening tangled rattan tea. A heating device is used to maintain an appropriate loosening temperature.

[0005] Preferably, the rattan tea loosening machine includes a metering conveyor located on one side of the loosening drum's feeding section. The metering conveyor is equipped with a heat preservation box, which contains a conveyor belt and a weighing device. One end of the conveyor belt is connected to a feeding hopper corresponding to the feeding section of the loosening drum. The heat preservation box on the metering conveyor temporarily stores the rattan tea from the previous process during the loosening drum's loosening process, maintaining its temperature and preventing the rattan tea from cooling down during continuous production, thus avoiding changes in the process parameters of the loosening process and ensuring the quality of the rattan tea. The weighing device measures the rattan tea entering the loosening drum, ensuring that the weight of the rattan tea delivered to the loosening drum each time meets the process requirements; the conveyor belt transports the rattan tea to the loosening drum.

[0006] Preferably, the metering conveyor is mounted on a conveyor frame, which is equipped with a slide rail. Rollers for the metering conveyor are also mounted on the conveyor frame, which is further equipped with a push rod connected to the metering conveyor. The push rod is used to push the metering conveyor on the slide rail towards the loosening drum, so that the feeding hopper can connect with the loosening drum and smoothly transfer the rattan tea.

[0007] Preferably, the frame includes a fixed frame and an adjustable frame. The fixed frame has a rotating shaft, and the adjustable frame is connected to the fixed frame via the rotating shaft. The fixed frame also has a lifting mechanism, and one side of the adjustable frame is connected to the lifting mechanism. In this invention, the adjustable frame is connected to the fixed frame via the rotating shaft. The angle of the unloading roller is adjustable, and the unloading roller is tilted during discharge, which facilitates the flow of the vine tea from the unloading roller. The unloading roller is connected to a drive shaft and a motor via a chain, and one end of the drive shaft is equipped with a crank handle. The crank handle is used to manually crank the unloading roller to remove the vine tea during a power outage.

[0008] Preferably, the inner wall of the loosening roller is provided with an installation strip, and the loosening teeth are fixed on the installation strip. There are 2-4 rows of loosening teeth, the central angle between two adjacent rows of loosening teeth is 15-55 degrees, and the length of the loosening teeth is 8-12 cm.

[0009] Preferably, the inner diameter of the feeding section of the loosening roller is the same as the inner diameter of the middle section of the loosening roller, and the discharge section of the loosening roller has a funnel-shaped structure that tapers at the outlet end. The rotation direction of the feeding spiral guide ribs in the feeding section is opposite to that of the discharge spiral guide ribs in the discharge section. When the loosening roller rotates forward, the feeding and discharge spiral guide ribs work together to guide the rattan tea to the middle section of the loosening roller for loosening. During discharge, the loosening roller reverses direction, with one side of the feeding section rising and the other side of the discharge section lowering, facilitating the flow of rattan tea from the discharge section.

[0010] Preferably, some of the loosening teeth have a groove on the front side in the forward rotation direction. An elastic strip is provided in the groove. One end of the elastic strip near the inner wall of the loosening roller is rotatably connected to the groove wall. The other end of the elastic strip is connected to the bottom of the groove through a compression spring. The elastic strip has a long groove that passes through the elastic block. A cutter corresponding to the long groove is fixed at the bottom of the groove. When the elastic strip pops out, the cutting edge of the cutter is located in the long groove. When the elastic strip is compressed, the cutting edge of the cutter extends out of the long groove. This invention features an elastic strip and a cutter on the front side of some loosening teeth in the forward rotation direction. During normal operation, the elastic strip is in a popped-out state under the elastic force of the compression spring, and the blade of the cutter is located inside the long groove on the elastic strip, having no effect on the rattan tea. On the other hand, the popped-out shape helps the loosening teeth catch the rattan tea, exerting a pulling effect and facilitating the dispersion of the rattan tea. However, when the rattan tea is very tightly wrapped and difficult to untangle, the pressure acting on the elastic strip is greater. At this time, the elastic strip overcomes the elastic force of the compression spring and is pressed down, exposing the blade of the cutter inside the long groove of the elastic strip. This cuts the tightly wrapped rattan tea, causing some of the wrapped rattan tea to break, thereby achieving the purpose of dispersing the rattan tea. This structure can accelerate the unwrapping speed of rattan tea and improve the unwrapping efficiency.

[0011] Preferably, the hinge end of the elastic strip is a rectangular block, which is used to limit the maximum rotation angle of the elastic strip, so that the elastic strip in the popped state has a reasonable tilt angle relative to the axis of the loose teeth.

[0012] Preferably, the loosening teeth are positioned in the first row of the loosening roller in the forward rotation direction, with a spacing of 10-16 cm between teeth in the same row, and adjacent rows of loosening teeth are staggered. Here, the first row in the rotation direction refers to the row where, when the loosening roller rotates forward, the offset loosening teeth are the first to contact the rattan tea on the smooth surface of the loosening roller wall (the side opposite the loosening teeth). The staggered arrangement of adjacent rows of loosening teeth increases the probability of contact between the loosening teeth and the rattan tea. Since the cutting blades on the loosening teeth are usually designed for larger rattan tea clumps, it is unnecessary to install them on every single loosening tooth. Furthermore, too many cutting blades would negatively impact the appearance quality of the rattan tea; therefore, they are usually distributed along the axial direction of the loosening roller to save costs.

[0013] Preferably, the cutting edge of the cutter is inclined, with one end of the cutter away from the inner wall of the unloading roller higher than the other end and parallel to the elastic strip in the pop-up state. When the elastic strip is in the pop-up state, the angle between the elastic strip and the unloading teeth is 3-8 degrees. A pressure adjusting screw is provided at the bottom of the groove corresponding to the compression spring, and a locking nut is provided on the pressure adjusting screw. The slightly inclined cutting edge of the cutter is beneficial for cutting; the spring force of the compression spring on the elastic strip can be adjusted by the pressure adjusting screw to meet different processing requirements.

[0014] The method for loosening tea leaves using a tea loosening machine includes the following steps:

[0015] a. The vine tea completed in the previous process is fed into a metering conveyor for heat preservation and weighing;

[0016] b. The push rod on the conveyor frame pushes the metering conveyor to move towards the feeding section of the loosening drum. The feeding hopper on the metering conveyor enters the feeding section of the loosening drum. The conveyor belt on the metering conveyor rotates and feeds the rattan tea into the loosening drum. The push rod of the lifting mechanism extends to make the loosening drum horizontal. The temperature inside the loosening drum is 55-60 degrees Celsius.

[0017] c. The loosening drum rotates in the forward direction. The feeding spiral guide ribs of the feeding section of the loosening drum push the moving rattan tea towards the middle section of the loosening drum. When the rattan tea reaches the discharge section of the loosening drum, the discharge spiral guide ribs of the discharge section push the moving rattan tea towards the middle section of the loosening drum.

[0018] d. The loosened teeth cause the vine tea to move upwards, and the vine tea falls from a high position and gradually disperses;

[0019] e. After the rattan tea is unpacked, the lifting mechanism retracts its top rod, the feeding section of the unpacking drum rises on one side and the discharge section on the other side, and the unpacking drum rotates in the opposite direction. When the rattan tea reaches the discharge section of the unpacking drum, the discharge spiral guide ribs of the discharge section push the rattan tea out of the unpacking drum.

[0020] Preferably, the loose tooth is provided with an elastic strip and a cutting blade on its front side in the positive rotation direction, and the method further includes the following steps:

[0021] When the tangled vine tea is heavy, the elastic strip is pressed down by the weight of the vine tea, the blade of the cutting knife is exposed, and part of the vine tea is cut off, causing the tangled vine tea to disperse.

[0022] The beneficial effect of this invention is that it effectively solves the problem that vine tea is very easy to clump together and entangle during processing, and that it is very difficult to loosen the vine tea bundles. The vine tea loosening machine and loosening method of this invention have the advantages of simple structure, good loosening effect and can meet the requirements of continuous production, and have high practicality.

[0033] The specific implementation of the technical solution of the present invention will be further described below through examples and in conjunction with the accompanying drawings.

[0034] Example 1

[0035] In such Figure 1 Figure 2 Figure 3 In Embodiment 1 shown, a rattan tea loosening machine includes a frame with a loosening roller 1 horizontally arranged on it. The frame includes a fixed frame 17 and an adjusting frame 18. A rotating shaft is provided on the fixed frame, and the adjusting frame is connected to the fixed frame via the rotating shaft. A lifting mechanism 19 is also provided on the fixed frame, and one side of the adjusting frame is connected to the lifting mechanism. The angle of the loosening roller is adjustable, and the loosening roller is tilted during discharge, which facilitates the flow of rattan tea from the loosening roller. The loosening roller is connected to a drive shaft 31 and a motor 29 via a chain 30 (see...). Figure 9 The drive shaft is equipped with a crank handle 32 at one end; the crank handle is used to manually crank the loosening roller to remove the rattan tea during a power outage. The loosening roller has a feeding section 2 and a discharging section 3 at both ends, with feeding spiral guide ribs 4 and discharging spiral guide ribs 5 on the inner walls of the feeding and discharging sections, respectively. The middle section 6 of the loosening roller has several rows of axially arranged loosening teeth 7 on its inner wall. The loosening teeth are cylindrical and offset on the circumferential surface of the inner wall of the loosening roller. A heating device 8 is provided on the outer circumference of the loosening roller to maintain a suitable loosening temperature. The rattan tea loosening machine includes a metering conveyor 9 located on one side of the feeding section of the loosening roller. The metering conveyor is equipped with a heat preservation box 10, which contains a conveyor belt 11 and a weighing device. One end of the conveyor belt is connected to a feeding hopper 12 corresponding to the feeding section of the loosening roller. The insulated box on the metering conveyor is used to temporarily store the rattan tea from the previous process during the unpacking of rattan tea on the unpacking roller. This insulation prevents the rattan tea from cooling down during its transfer on the continuous production line, which could alter the process parameters of the unpacking process and ensure the quality of the rattan tea. The weighing device measures the weight of the rattan tea entering the unpacking roller, ensuring that the weight of each shipment meets the process requirements. The conveyor belt transports the rattan tea to the unpacking roller.

[0036] In this embodiment, the metering conveyor is mounted on a conveyor frame 13, which is equipped with a slide rail 14. Metering conveyor rollers 15 are also mounted on the conveyor frame, which is further equipped with an electric push rod 16 connected to a lug plate at the bottom of the metering conveyor. When the electric push rod extends, it pushes the metering conveyor on the slide rail towards the loosening drum, allowing the feeding hopper to align with the loosening drum and smoothly transfer the rattan tea. When the electric push rod retracts, the metering conveyor moves away from the loosening drum and aligns with the previous process, receiving the rattan tea from the previous process and keeping it warm.

[0037] In this embodiment, the inner wall of the loosening roller is provided with mounting strips 20, and loosening teeth are fixed on the mounting strips. In this embodiment, there are 3 rows of loosening teeth. The central angle between the first row of loosening teeth and the second row of loosening teeth is greater than the central angle between the second row of loosening teeth and the third row of loosening teeth. The length of the loosening teeth is 10 cm. Here, the first row refers to the row of offset loosening teeth that comes into contact with the rattan tea first when the loosening roller rotates in the forward direction. The central angle between the first row of loosening teeth and the second row of loosening teeth is greater than the central angle between the second row of loosening teeth and the third row of loosening teeth. In this way, the rattan tea that is pulled and dispersed by the first row of loosening teeth has more space before it encounters the second row of loosening teeth. That is, when the clump of rattan tea rises under the agitation of the first row of loosening teeth, the rattan tea that is not directly caught by the first row of loosening teeth has more stretching space when it slides down the inner wall of the loosening roller under the action of gravity. This is more conducive to the dispersion of rattan tea. In this embodiment, the central angle between the first and second rows of loose teeth is 50 degrees, and the central angle between the second and third rows of loose teeth is 20 degrees.

[0038] In this embodiment, the inner diameter of the feeding section of the loosening roller is the same as the inner diameter of the middle section of the loosening roller. The discharge section of the loosening roller has a funnel-shaped structure with a narrowing outlet end. The rotation direction of the feeding spiral guide ribs in the feeding section is opposite to that of the discharge spiral guide ribs in the discharge section. When the loosening roller rotates forward, the feeding and discharge spiral guide ribs work together to guide the rattan tea to the middle section of the loosening roller for loosening. During discharge, the loosening roller reverses direction, and one side of the feeding section of the loosening roller rises, facilitating the flow of rattan tea from the discharge section.

[0039] The loosening method of the rattan tea loosening machine in Example 1 includes the following steps:

[0040] a. The vine tea that has been processed in the previous step is fed into a metering conveyor for heat preservation and weighing; in this embodiment, the weight of the vine tea unpacked each time is 25 kg, and the temperature of the heat preservation box is 50-55 degrees.

[0041] b. The push rod on the conveyor frame pushes the metering conveyor to move towards the feeding section of the loosening drum. The feeding hopper on the metering conveyor enters the feeding section of the loosening drum. The conveyor belt on the metering conveyor rotates and feeds the rattan tea into the loosening drum. The push rod of the lifting mechanism extends to make the loosening drum horizontal. The temperature inside the loosening drum is 55-60 degrees Celsius.

[0042] c. The loosening drum rotates in the forward direction. The feeding spiral guide ribs of the feeding section of the loosening drum push the moving rattan tea towards the middle section of the loosening drum. When the rattan tea reaches the discharge section of the loosening drum, the discharge spiral guide ribs of the discharge section push the moving rattan tea towards the middle section of the loosening drum.

[0043] d. The loosened teeth cause the vine tea to move upwards, and the vine tea falls from a high position and gradually disperses;

[0044] e. After the rattan tea is unpacked, the lifting mechanism retracts its top rod, the feeding section of the unpacking roller rises on one side, and the discharge section on the other side lowers. The unpacking roller rotates in the opposite direction. When the rattan tea reaches the discharge section of the unpacking roller, the discharge spiral guide ribs push the rattan tea out of the unpacking roller. The unpacking time for rattan tea is usually 3-5 minutes.

[0045] Example 2

[0046] In addition to the structure of Embodiment 1, the loosening teeth of Embodiment 2 are columnar structures with a square cross-section. Some loosening teeth have grooves 21 on their front side (i.e., the side in contact with the rattan tea) in the forward rotation direction. Elastic strips 22 are provided in the grooves. One end of the elastic strip near the inner wall of the loosening roller is connected to the groove wall via a rotating shaft 23, and the other end of the elastic strip is connected to the bottom of the groove via a compression spring 24. The elastic strip has a long groove 25 that penetrates the elastic block (see...). Figure 8 The bottom of the groove is fixed with a cutting blade 26 corresponding to the long groove. When the elastic strip pops out, the cutting edge 27 of the cutting blade is located in the long groove (see...). Figure 4 Figure 5 When the elastic strip is compressed, the cutting edge of the cutter extends out of the long groove (see...). Figure 6 Figure 7The hinge end of the elastic strip is a rectangular block, used to limit the maximum rotation angle of the elastic strip, so that the elastic strip in the popped state has a reasonable tilt angle relative to the axis of the loosening teeth. An elastic strip and a cutter are provided on the front side of some loosening teeth in the positive rotation direction. During normal operation, the elastic strip is in the popped state under the elastic force of the compression spring, and the blade of the cutter is located inside the long groove on the elastic strip, having no effect on the rattan. On the other hand, the popped shape helps the loosening teeth catch the rattan, exerting a pulling effect and facilitating the dispersion of the rattan. However, when the rattan is very tightly wrapped and difficult to untangle, the pressure acting on the elastic strip is greater. At this time, the elastic strip overcomes the elastic force of the compression spring and is pressed down. The blade of the cutter inside the long groove of the elastic strip is exposed, cutting some of the very tightly wrapped rattan, causing some of the wrapped rattan to break, thereby achieving the purpose of dispersing the rattan. This structure can accelerate the unwrapping speed of the rattan and improve the unwrapping efficiency.

[0047] In this embodiment, the loosening teeth are arranged in the first column in the direction of rotation of the loosening roller, with a spacing of 12 cm between teeth in the same column, and adjacent columns of loosening teeth are staggered. Here, the first column in the direction of rotation refers to the column in which the offset loosening teeth first come into contact with the rattan tea on the smooth surface of the loosening roller wall (the side opposite to the loosening teeth) when the loosening roller rotates in the forward direction. The staggered arrangement of adjacent columns of loosening teeth can increase the probability of contact between the loosening teeth and the rattan tea.

[0048] In this embodiment, the cutting edge of the cutter is inclined, with one end of the cutter away from the inner wall of the unloading roller higher than the other end and parallel to the elastic strip in the pop-up state. When the elastic strip is in the pop-up state, the angle between the elastic strip and the unloading teeth is 5 degrees. A pressure adjusting screw 28 is provided at the bottom of the groove corresponding to the compression spring, and a locking nut is provided on the pressure adjusting screw. The slightly inclined cutting edge of the cutter is beneficial for cutting; the spring force of the compression spring on the elastic strip can be adjusted by the pressure adjusting screw to meet different processing requirements.

[0049] The unpacking method of the rattan tea unpacking machine in Example 2, in addition to the unpacking steps in Example 1, also includes the following steps:

[0050] When the tangled vine tea is heavy, the elastic strip is pressed down by the weight of the vine tea, the blade of the cutting knife is exposed, and part of the vine tea is cut off, causing the tangled vine tea to disperse.

[0051] The loosening roller of this invention has loosening teeth on the inner wall of the middle section. When the loosening roller rotates, the loosening teeth agitate the rattan tea, which can disperse the rattan tea. At the same time, when the rattan tea is pulled upward by the loosening teeth, some rattan tea that is not directly pulled by the loosening teeth will fall downward, which plays a role in dispersing. In addition, the loosening teeth of this invention are set in an offset manner rather than a uniform distribution in the circumferential direction of the loosening roller. At least half of the arc surface of the loosening roller is a smooth surface. In this way, when the rattan tea is dropped from a high point, it will not be blocked by the loosening teeth, so that the rattan tea has more stretching space as it falls under the action of gravity. Practice has proven that this is more conducive to the dispersion of rattan tea and solves the problem that rattan tea is very easy to clump together and entangle, and that it is very difficult to loosen rattan tea.

[0052] In addition to the above embodiments, within the scope disclosed in the claims and specification of this invention, the technical features or technical data of this invention can be reselected and combined to form new embodiments. These can be achieved by those skilled in the art without creative effort. Therefore, these embodiments not described in detail in this invention should also be regarded as specific embodiments of this invention and within the protection scope of this invention. Furthermore, the devices or structures not described in detail in this invention are all well-known technologies in this field.
