Description

Technical Field

[0001] The utility model relates to the technical field of tea packaging, in particular to a tea blending continuous packaging device. Background Art

[0002] Tea is mostly grown in the south, where the climate is warm and humid. In order to ensure that tea can be stored for a long time, it is often necessary to keep the tea dry during the packaging process. At the same time, in order to maintain the quality of tea products, companies need to evenly mix teas from different years or different production areas according to a set ratio during the production process. This process is called tea blending, and the blended products are finally processed or packaged.

[0003] The existing patent document with announcement number CN219339953U discloses a tea drying, blending and self-mixing packaging machine. When in use, multiple types of tea are placed in a raw material storage and drying device and dried. After the tea is dried to meet the production and packaging requirements, the unloading sealing plate at the end of the raw material storage and drying device is controlled to open, and multiple types of tea fall on the rotating disk under their own weight at the same time, and the first blending and mixing is carried out. The rotating disk rotates under the driving action of the driving motor, and then falls to the shrinking plate through multiple "eight"-shaped protrusions on the rotating disk. During this process, due to the change in the diameter of the protrusions and the shrinking plate, the tea is mixed for the second time. Then the tea falls into the vertical self-mixing device under the action of gravity. During the falling process, it is blocked by the second mixing piece on the cylinder wall, and the tea is impacted and dispersed, and automatic mixing is achieved. Finally, it is output from the discharge port and packaged. Through the above-mentioned setting, this scheme saves equipment floor space, realizes the one-time completion of tea drying, blending, and mixed packaging processes, ensures the effect of tea mixing, and improves work efficiency. At the same time, through drying before packaging, the moisture content of tea is controlled, and the product quality is improved.

[0025] The screening mechanism 6 comprises a screen 61 movably arranged in the inner cavity of the mixing box 1 and located below the mixing mechanism 5 , and at least two symmetrically arranged limiting members 62 for guiding are arranged between the bottom of the screen 61 and the inner wall of the mixing box 1 .

[0026] It should be noted that the structures and working principles of the above-mentioned storage and drying device 2 and the bracket 4 are consistent with the prior art, so they will not be described in detail in this technical solution.

[0027] Working principle: by placing various types of tea leaves in corresponding storage and drying devices 2 for drying, after drying, they can be discharged into the inner cavity of mixing box 1, so that various types of tea leaves are piled up above screen 61, and motor 51 is started. The output shaft of motor 51 drives worm 71, rotating rod 52 and stirring rod 53 to rotate, and various types of tea leaves above screen 61 can be mixed by stirring rod 53 to achieve blending effect; at the same time, worm 71 drives worm wheel 75 to rotate, worm wheel 75 drives upper movable rod 72 to rotate, upper movable rod 72 drives lower movable rod 73 to rotate through pulley and belt, and lower movable rod 73 drives eccentric wheel 74 to rotate, when eccentric wheel 74 rotates 180 degrees, eccentric wheel 74 pushes screen 61 to move upward, and screen 61 drives guide rod 622 to support The inner cavity of the sleeve 621 slides, and the spring 623 is stretched by force. When the eccentric wheel 74 rotates 360 degrees, the screen 61 loses its constraint, and the screen 61 moves downward through the self-weight of the screen 61 and the tea leaves and the elastic force of the spring 623. Therefore, each rotation of the eccentric wheel 74 will drive the screen 61 to move up and down once, and the screen 61 can vibrate up and down over and over again, so that a variety of tea leaves above the screen 61 can be screened to achieve the screening effect. The tea leaves with larger particles still remain above the screen 61, and the tea leaves with smaller particles fall into the inner cavity of the bracket 4 through the filter holes. The blended and screened tea leaves can be discharged and packaged by opening the valve; the tea leaves with larger particles above the screen 61 can be discharged by opening the sealing plate 8 for separate collection and treatment.

[0028] Beneficial effect: by starting the motor 51, the output shaft of the motor 51 can drive the stirring rod 53 to rotate, so that the tea leaves above the screen 61 can be mixed to achieve the blending effect. At the same time, the output shaft of the motor 51 drives the screen 61 to vibrate up and down through the transmission mechanism 7, so that the tea leaves above the screen 61 can be screened to achieve the screening effect, which is beneficial to the uniformity of the tea particles in the subsequent packaging process, improves the uniformity of the tea particles, and further improves the aesthetics. Through the coordinated use of the mixing box 1, the storage and drying device 2, the discharge pipe 3, the mixing mechanism 5, the screening mechanism 6 and the transmission mechanism 7, the tea drying, blending, mixing and screening processes are completed at one time, achieving the mechanization of the entire packaging process, continuous operation and high packaging efficiency.

[0029] Example 2

[0030] Please refer to Figure 1-Figure 4 As shown, the tea blending continuous packaging device provided in this embodiment is different from that in embodiment 1 in that:

[0031] The mixing mechanism 5 includes a motor 51 installed at the center of the top of the mixing box 1. The output shaft of the motor 51 penetrates the inner cavity of the mixing box 1 and is vertically provided with a rotating rod 52. The lower part of the surface of the rotating rod 52 is fixedly connected with at least two groups of symmetrically arranged stirring rods 53, and each group of stirring rods 53 is provided with two stirring rods 53 in an upper and lower position. With the above design, by starting the motor 51, the output shaft of the motor 51 can drive the stirring rod 53 to rotate with the output shaft of the motor 51 as the axis, thereby being able to evenly mix the tea leaves above the screening mechanism 6 to achieve the effect of blending and packaging.

[0032] The limiting member 62 includes a support sleeve 621 fixedly connected to the inner wall of the mixing box 1, and the inner cavity of the support sleeve 621 is slidably connected with a guide rod 622, which is an inverted T-shaped structure, and the top of the guide rod 622 is fixedly connected to the bottom of the screen 61. The above design can drive the guide rod 622 to slide in the inner cavity of the support sleeve 621 when the screen 61 moves up and down, effectively improving the stability of the screen 61 when it moves up and down, and limiting the up and down movement range of the screen 61.

[0033] The surface of the guide rod 622 is sleeved with a spring 623, and the top and bottom ends of the spring 623 are respectively fixedly connected to the bottom of the screen 61 and the top of the support sleeve 621. The above design, through the elastic force of the spring 623, can automatically reset the screen 61, and can also buffer the up and down movement of the screen 61.

[0034] The transmission mechanism 7 includes a worm 71 fixedly connected between the output shaft of the motor 51 and the rotating rod 52. The inner cavity of the mixing box 1 is horizontally connected to the upper movable rod 72 through a bearing, and a lower movable rod 73 is horizontally arranged below the screen 61. One end of the upper movable rod 72 and the lower movable rod 73 are movable to penetrate the outside of the mixing box 1 and are connected through a pulley and a belt transmission. The other end of the lower movable rod 73 is fixedly connected to an eccentric wheel 74 in contact with the bottom of the screen 61. With the above design, when the rotating rod 52 rotates, the eccentric wheel 74 can be driven to rotate through the coordinated use of the worm 71, the worm wheel 75 and the lower movable rod 73, and then the screen 61 can be driven to move up and down to achieve the function of screening the tea leaves above the screen 61.

[0035] The surfaces of the upper movable rod 72 and the lower movable rod 73 are rotatably connected to the penetration of the mixing box 1 through bearings. The above design can support the upper movable rod 72 and the lower movable rod 73, and help ensure the stability of the upper movable rod 72 and the lower movable rod 73 when rotating.

[0036] The screen 61 is tilted, and the horizontal line on the left side of the screen 61 is lower than the horizontal line on the right side. The surface of the mixing box 1 is hinged with a sealing plate 8 used in conjunction with the screen 61. With the above design, when the screen 61 vibrates up and down for screening, the tea leaves with larger particles on the screen 61 can move toward the sealing plate 8 by their own gravity and the force of the tilted screen 61, which helps to discharge the tea leaves with larger particles on the screen 61 later.

[0037] The surface of the mixing box 1 is fixedly connected with a side box 9 for protecting the pulley and the belt. The above design helps to improve the safety of the pulley and the belt during transmission.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
