DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] At present, the traditional berry tea production and processing is mainly manual scattered processing, and the quality of manual frying is unstable. The quality of frying depends entirely on the personal level of the skilled workers. In addition, during the frying process, the workers' hands have to stir the tea continuously at high temperatures, and the labor intensity of bending over for a long time is extremely high, and the working conditions are poor. At the same time, the sanitary conditions of the traditional production method are poor, and manual operation will increase the risk of sanitary pollution. The quality of the processed berry tea is unstable and the production efficiency is low. Therefore, the market is in urgent need of developing continuous complete processing equipment.

[0018] See also Figure 1 and Figure 2 The present embodiment provides a continuous tea loosening machine, including a bracket 1, on which a loosening drum 2 is arranged, a feeding box 3 is arranged on the bracket 1 and located on one side of the loosening drum 2, and also includes a first driving member 4 for driving the loosening drum 2 to rotate, the loosening drum 2 includes a feed port 5 and a discharge port 6, wherein the feeding box 3 transports tea leaves from the feed port 5 into the loosening drum 2, loosens the tea leaves through the loosening drum 2, and then outputs the tea leaves from the discharge port 6.

[0019] The loosening drum 2 loosens the tea balls mainly by providing a baffle 7 on the inner wall of the loosening drum 2 , the length direction of the baffle 7 is in the same direction as the axial direction of the loosening drum 2 , and a discharge spiral guide plate 8 is provided at the discharge port 6 of the loosening drum 2 .

[0020] As the loosening drum 2 rotates, the tea balls in the loosening drum 2 also move, wherein the baffle 7 also rotates together. The baffle 7 makes the tea balls move to a higher position in the loosening drum 2 and then fall down, so that the tea balls are gradually scattered. The scattered tea leaves are transported to the outside at the outlet along the discharge spiral guide plate.

[0021] During the rotation of the loosening drum 2, the tea balls formed by different teas have different degrees of compactness. For example, the buds and leaves of yellow tea are smaller and the compactness of the balls is smaller, while two or three pieces of white tea are pinched together, so that the balls are tightly entangled with each other. At the same time, the kneading strength is different, and the time for the tea leaves to be dispersed is also different. Therefore, if the movement is carried out according to the same process, it is easy for some tea balls to be discharged from the discharge port without being dispersed.

[0022] See also Figure 2 and Figure 4To solve the above technical problems, a cover 9 is provided on one side of the loosening drum 2 located at the feed port 5, and the lower side of the cover 9 is connected to the bracket 1 through a hinge 10, and the bracket 1 is provided with an adjustment mechanism 11 for adjusting the height difference between the feed port 5 and the discharge port 6.

[0023] In the initial state, the axis of the loosening drum 2 is in a horizontal state. As can be seen from the figure, during the process of dispersing the tea leaves by the rotation of the feeding drum, as the loosening drum 2 moves forward, it is adjusted through the adjusting mechanism 11. When discharging is required, the height of the discharge port 6 is made lower than the initial height of the discharge port 6, that is, the axis of the loosening drum 2 is tilted, so that the tea leaves are loosened in the loosening drum 2 while moving toward the discharge port 6. If there are still undispersed clumps of tea leaves in the loosening machine, the height of the discharge port 6 is driven lower than the initial height of the discharge port 6 through the adjusting mechanism 11, so that during the rotation of the loosening drum 2, the tea leaves will gradually move toward the direction of the feed port 5, and will not be discharged from the discharge port 6 temporarily.

[0024] See also Figure 2 and Figure 3 A limiting groove 91 is provided on the inner wall of the cover 9 , and a convex ring 92 is fixedly installed on the side surface of the loosening drum 2, and the convex ring 92 is located in the limiting groove 91 .

[0025] The interaction force between the convex ring 92 and the inner wall of the limiting groove 91 enables the loosening drum 2 and the cover 9 to rotate relative to each other without separation.

[0026] See also Figure 4 and Figure 5 The hinge 10 includes a shaft 101 fixedly mounted on the cover 9 , the shaft 101 is axially perpendicular to the loosening drum 2 , and a ferrule 102 is sleeved on the side surface of the shaft 101 , and the ferrule 102 is fixedly mounted on the bracket 1 .

[0027] When the adjustment mechanism 11 adjusts the height of the discharge port 6, since a cover 9 is provided on one side of the loosening drum 2 and the cover 9 can only rotate around the axis of the shaft 101, when the height of the discharge port 6 of the loosening drum 2 is adjusted, the loosening drum 2 also rotates around the shaft 101 to control the position of the discharge port 6.

[0028] See also Figure 4-Figure 6 The adjusting mechanism 11 specifically includes a limiting ring 111 fixedly installed on the side of the loosening drum 2, a supporting ring 112 is rotatably arranged on the outer side of the limiting ring 111, a connecting rod 113 is fixedly installed on the lower side of the supporting ring 112, rollers 114 are rotatably installed on both sides of the connecting rod 113, a slide rail 115 is arranged on the lower side of the roller 114, a strip 116 for blocking the roller 114 is fixedly installed on the upper side of the slide rail 115, and a second driving member 117 for driving the slide rail 115 to move in the vertical direction is arranged on the lower side of the slide rail 115.

[0029] The second driving member 117 is specifically a telescopic cylinder, a pneumatic cylinder, a hydraulic cylinder or a manually adjustable screw drive.

[0030] When the adjusting mechanism 11 adjusts the discharge port 6 of the loosening drum 2, the second driving member 117 drives the slide rail 115 to move in the vertical direction. When it is necessary to move upward, the interaction force between the inner wall of the slide rail 115 and the roller 114 is used to push the roller 114 upward, thereby pushing the connecting rod 113 and the loosening drum 2 upward. When it is necessary to move downward, the interaction force between the strip 116 and the roller 114 is used to drive the roller 114 downward, thereby driving the connecting rod 113 and the loosening drum 2 downward, thereby realizing the height adjustment of the discharge port 6.

[0031] See also Figure 6 The loosening drum 2 rotates, so that the limiting ring 111 rotates relative to the supporting ring 112, and the friction between the two is relatively large. In order to reduce the friction, a ball 118 is rotatably mounted on the side surface of the limiting ring 111, and an annular groove 119 is provided on the inner wall of the supporting ring 112, and the ball 118 contacts the inner wall of the annular groove 119.

[0032] Through the contact between the ball 118 and the inner wall of the annular groove 119, when the limit ring 111 and the support ring 112 rotate relatively, the ball 118 contacts the inner wall of the annular groove 119 and the ball 118 rotates, thereby generating rolling friction and reducing friction.

[0033] See also Figure 1 and Figure 2 A feeding pipe 12 is provided on the side of the cover 9 away from the loosening drum 2 , and the feeding pipe 12 is connected to the feeding box 3 .

[0034] See also Figure 5 In order to further improve the loosening efficiency of tea balls, a stirring rod 13 is arranged inside the loosening drum 2, the axis of the stirring rod 13 coincides with the axis of the loosening drum 2, and multiple groups of insertion rods 14 are arranged circumferentially on the side of the stirring rod 13, each group of insertion rods 14 has multiple rods, which are arranged along the axial direction of the stirring rod 13, and the loosening drum 2 is provided with a third driving member 15 for driving the stirring rod 13 to rotate.

[0035] The first driving member 4 drives the loosening drum 2 to rotate. The baffle 7 in the loosening drum 2 loosens the tea balls on the one hand and carries the tea balls to the upper side of the inner wall of the loosening drum 2 on the other hand. Then the tea balls fall onto the insertion rod 14 of the stirring rod 13 under the action of gravity. The third driving member 15 drives the stirring rod 13, and the stirring rod 13 moves to facilitate the loosened tea leaves to fall through the gap between the insertion rods 14. At the same time, for the tea balls that have not fallen, the tea balls on the upper side of the stirring rod 13 are rotated to the lower side of the stirring rod 13 to facilitate the tea balls to fall from the insertion rod 14 on the stirring rod 13 to prevent accumulation, thereby improving the loosening efficiency of the tea balls.

[0036] See also Figure 5 and Fig. 9 In order to further improve the loosening efficiency of the tea leaves after they fall onto the stirring rod 13, a through hole 16 is provided on the side of the stirring rod 13 away from the first driving member 4, a support rod 17 is provided in the through hole 16, a disc 18 is fixedly installed on the side of the support rod 17 away from the first driving member 4, the axis of the disc 18 does not coincide with the axis of the support rod 17, and a fourth driving member 19 for driving the disc 18 to rotate around its own axis is fixedly installed on the cover 9.

[0037] The fourth driving member 19 is a rotating motor.

[0038] When a tea ball stays on the insertion rod 14 on the stirring rod 13, the fourth driving member 19 drives the disc 18 to rotate. Since the axis of the disc 18 does not coincide with the axis of the support rod 17, the support rod 17 grabs in the through hole 16 and continuously collides with the inner wall of the through hole 16. As the rotation frequency of the fourth driving member 19 increases, the number of collisions between the support rod 17 and the inner wall of the through hole 16 also increases, so that the stirring rod 13 is in a shaking state, and the tea ball that falls on the insertion rod 14 will also scatter during the shaking process, and then scatter downward from the gap between the insertion rods 14.

[0039] See also Figure 5 , Figure 7 and Figure 8 , where the stirring rod 13 is in a vibrating state, so the parts between the stirring rod 13 and the third driving member 15 are seriously worn. In order to solve the wear of the parts, at least one magnetic ring 131 is arranged on the side of the stirring rod 13 close to the third driving member 15, and the axis of the magnetic ring 131 coincides with the axis of the stirring rod 13. A magnetic column 132 is arranged inside the magnetic ring 131, and the outer surface of the magnetic column 132 has the same magnetic pole as the inner wall of the magnetic ring 131. There is a gap between the magnetic column 132 and the magnetic ring 131. A connecting disk 133 is fixedly installed on the side of the magnetic column 132 away from the stirring rod 13, and the axis of the connecting disk 133 coincides with the axis of the stirring rod 13. The third driving member 15 drives the connecting disk 133 to rotate.

[0040] When the third driving member 15 needs to drive the stirring rod 13 to rotate, the third driving member 15 first drives the connecting disk 133 to rotate, and the magnetic column 132 on the connecting disk 133 will drive the magnetic ring 131 to move around the axis of the connecting disk 133, thereby driving the stirring rod 13 to rotate, wherein the magnetic column 132 and the magnetic ring 131 are never in contact with each other, and only rely on the magnetic field repulsion force between the two. Therefore, during the shaking process of the stirring rod 13, the magnetic column 132 and the magnetic ring are never in contact, thereby reducing the wear of components, facilitating the shaking of the stirring rod 13, and increasing the shaking amplitude and frequency.

[0041] In order to maintain the temperature in the bag loosening machine, a heating element is provided in the bag loosening machine to prevent the temperature of the tea from gradually decreasing during the bag delivery process.

[0042] A method for loosening tea bags using a continuous tea bag loosening machine: S1, feeding the tea balls in the feeding box 3 into the loosening drum 2 through the feeding pipe 12; S2, the first driving member 4 drives the loosening drum 2 to rotate, and loosens the tea leaves in the loosening drum 2; S3, then the third driving member 15 rotates, driving the stirring rod 13 and the inserting rod 14 to rotate, and the inserting rod 14 further loosens the fallen tea leaves; S4, the fourth driving member 19 then drives the disc 18 to rotate, and the disc 18 drives the support rod 17 to rotate around the axis of the disc 18, so that the connecting rod 113 continuously collides with the inner wall of the through hole 16, so as to achieve the shaking of the stirring rod 13 and the insertion rod 14, thereby accelerating the loosening efficiency of the tea leaves; S5. During the rotation of the loosening drum 2, if the tea leaves are not dispersed to the standard, the second driving member 117 drives the discharge port 6 to lift upward, and the tea leaves in the loosening drum 2 will continue to roll; S6. After the tea leaves are properly dispersed, the second driving member 117 drives the discharge port 6 to lower its height. As the bag loosening drum 2 rotates, the tea leaves are poured out from the discharge port 6, thereby completing the tea bag loosening work.

[0043] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
