Description

Technical Field

[0001] This utility model relates to the technical field of tea production, and in particular to a tea packaging weighing device. Background Technology

[0002] Tea processing includes: withering: softening the leaves, increasing their plasticity, and facilitating shaping; and finishing: alternating between shaking and piling, consisting of two processes: shaking and air-drying. The ideal room temperature for finishing is around 25℃, with a relative humidity of around 80%. Shaking involves placing the withered tea leaves in a bamboo sieve and kneading them back and forth. This friction damages the leaf edge cells, and after spreading them out to lose moisture, the polyphenols in the leaves are gradually oxidized under the action of enzymes, forming the unique qualities of tea. Shaking should begin lightly and gradually increase in pressure to avoid breaking the stems and leaves, resulting in dead leaves (unripe tea). This would damage the quality of the tea.

[0003] After tea processing, when packaging the tea, in order to ensure the quality of the tea product, the tea needs to be weighed and poured into packaging bags. Generally, the weighed tea is pushed into the packaging bags manually, which increases the labor intensity. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a tea packaging weighing device that can directly pour the weighed tea onto the scale without the need for manual pouring.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A tea packaging weighing device includes a feeding rack and a receiving rack fixedly connected to its lower end. A feeding hopper is fixedly connected between the side walls of the feeding rack, and two receiving boxes are rotatably arranged between the side walls of the receiving rack.

[0008] A base frame is provided below the two weighing boxes, and the two weighing boxes are rotatably connected to the top of the base frame via a hinge.

[0009] Both weighing bins are equipped with a tilting mechanism for tilting and tilting the weighing bins to pour materials.

[0010] In a preferred embodiment, the present invention can be further configured as follows: the material pouring mechanism includes two traction ropes and two electric drums, the two traction ropes are fixedly connected to the upper end of the weighing box, the two electric drums are rotatably connected to the two side walls of the receiving frame, and the two traction ropes are fixedly connected to the circumferential sides of the two electric drums.

[0011] In a preferred embodiment, the present invention can be further configured such that: a rotating shaft is fixedly connected to the lower end of each receiving box, and a pouring motor for driving the rotation is provided on one side of each rotating shaft. The pouring motor is fixedly connected to one side of the receiving frame, and the output end of the pouring motor is fixed to the rotating shaft.

[0012] In a preferred embodiment, the present invention can be further configured as follows: the feeding hopper is divided into two hoppers by a partition plate, and two material dispersing rollers are rotatably connected between the side walls of the two hoppers. The feeding hopper is provided with two rotating mechanisms for driving the material dispersing rollers to rotate.

[0013] In a preferred embodiment, the present invention can be further configured such that: the rotating mechanism includes two gears rotatably connected to one side of the feeding hopper, and the two gears mesh with each other, and the gears are fixed to the rotating shaft of the material distribution roller.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings. Example

[0025] Reference Figure 1-4 The present invention discloses a tea packaging weighing device, including a feeding rack 9 and a receiving rack 4 fixedly connected to its lower end. A feeding hopper 5 is fixedly connected between the side walls of the feeding rack 9, and two receiving boxes 10 are rotatably arranged between the side walls of the receiving rack 4.

[0026] Below each of the two receiving boxes 10, there is a weighing box 2 with an opening on the side, and a weighing scale 3 is fixedly connected to the inner bottom wall of each of the two weighing boxes 2.

[0027] A base frame 1 is provided below the two weighing boxes 2, and the two weighing boxes 2 are rotatably connected to the top of the base frame 1 via hinges;

[0028] Both weighing bins 2 are equipped with a tilting mechanism for tilting and tilting the weighing bins 2 to pour materials.

[0029] In this embodiment, the preferred receiving rack 4 and feeding rack 9 are connected to the ground via a support. The receiving box 10 and weighing scale 3 achieve the purpose of secondary weighing, reducing errors. A fixed amount of tea can be loaded into the receiving box 10. The tea is added into the feeding hopper 5 and leaves from below the feeding hopper 5, falling into the receiving box 10. When the receiving box 10 is full, it rotates to pour the tea into the weighing box 2. After weighing by the weighing scale 3, when the appropriate weight is reached, the pouring mechanism drives the weighing box 2 to rotate, which can pour out the tea in the weighing box 2. The weighed tea can be poured out directly.

[0030] For further details, please refer to Figure 1The material pouring mechanism includes two traction ropes 12 and two electric drums 11. The two traction ropes 12 are fixedly connected to the upper end of the weighing box 2. The two electric drums 11 are rotatably connected to the two side walls of the receiving frame 4 respectively. The two traction ropes 12 are fixedly connected to the circumferential side of the two electric drums 11 respectively.

[0031] In this embodiment, when the weighing scale 3 weighs to a suitable weight, the traction rope 12 is wrapped around the surface of the electric drum 11, the electric drum 11 is started, the electric drum 11 rotates, the traction rope 12 is detached from the surface of the electric drum 11, the traction rope 12 becomes longer, and the weighing box 2 rotates downward with the hinge as the fulcrum due to gravity, pouring the tea leaves out of the weighing box 2. Preferably, the hinge of the weighing box 2 is located on the lower side.

[0032] For further details, please refer to Figure 2 Each receiving box 10 has a rotating shaft 18 fixedly connected to its lower end. A pouring motor 15 for driving the rotation of the rotating shaft 18 is provided on one side. The pouring motor 15 is fixedly connected to one side of the receiving frame 4, and the output end of the pouring motor 15 is fixed to the rotating shaft 18.

[0033] In this embodiment, after the receiving box 10 is filled with tea leaves, the pouring motor 15 is started. The output end of the pouring motor 15 drives the rotating shaft 18 to rotate, and the receiving box 10 starts to rotate, pouring the tea leaves into the weighing box 2.

[0034] For further details, please refer to Figure 2 The feeding hopper 5 is divided into two hoppers by a partition plate 16. Two material rollers 13 are rotatably connected between the side walls of the two hoppers. Two rotating mechanisms 8 are provided on the feeding hopper 5 to drive the material rollers 13 to rotate.

[0035] In this embodiment, the rotation of the material dispersing roller 13 can break up the piled-up tea leaves, preventing the tea leaves from being directly added into the receiving box 10, which would make them difficult to weigh.

[0036] For further details, please refer to Figure 3 The rotating mechanism 8 includes two gears 801 rotatably connected to one side of the feeding hopper 5, and the two gears 801 mesh with each other. The gears 801 are fixed to the rotating shaft of the material roller 13.

[0037] In this embodiment, the preferred rotating mechanism 8 also includes a base 802 and a rotating motor 803. The rotating motor 803 is mounted on the feeding hopper 5 via the base 802. Thus, the output of the rotating motor 803 drives one of the gears 801 to rotate. The preferred material distribution rollers 13 are provided with four material distribution rollers 13. The rotating mechanism 8 is provided with two sets. After the tea leaves are added into the feeding hopper 5, the gear 801 rotates and meshes with another gear 801. The two gears 801 drive the two material distribution rollers 13 to rotate. The material distribution rollers 13 can separate the tea leaves that are piled together, preventing the tea leaves from falling directly in one pile, and making it convenient to weigh the tea leaves.

[0038] For further details, please refer to Figure 4 Two springs 14 are fixedly connected to the upper end of the partition plate 16, and a feeding frame 6 is fixedly connected to the upper end of the two springs 14. Pushing mechanisms are provided on both sides of the feeding frame 6 for intermittently pushing the feeding frame 6 upward.

[0039] In this embodiment, when the material roller 13 rotates inside the feeding hopper 5, the feeding hopper 5 will shake. The spring 14, due to its own elasticity, will cause the feeding frame 6 to shake, so that the tea leaves can be evenly added into the feeding hopper 5.

[0040] For further details, please refer to Figure 1 The pushing mechanism includes a rotating block 7 rotatably disposed on one side of the feeding hopper 5, and a fixing plate 17 is disposed above the rotating block 7, and the fixing plate 17 is fixed to the side of the feeding frame 6.

[0041] In this embodiment, a drive motor is preferably provided on the rotating block 7. When the rotating block 7 rotates to the longer end, the rotating block 7 pushes the fixed plate 17 upward, and the spring 14 is in a stretched state. When the rotating block 7 rotates to the shorter end, the spring 14 pulls the feeding frame 6 downward due to its own elasticity, so that the feeding frame 6 can move up and down, making it convenient for the tea leaves to fall.

[0042] The implementation principle of the above embodiment is as follows: Tea leaves are added into the feeding hopper 5, and the tea leaves leave from the bottom of the feeding hopper 5 and fall into the receiving box 10. When the receiving box 10 is full, the pouring motor 15 is started. The output end of the pouring motor 15 drives the rotating shaft 18 to rotate, and the receiving box 10 starts to rotate. The receiving box 10 pours the tea leaves into the weighing box 2. The tea leaves can be poured into the weighing box 2 and weighed by the weighing scale 3. When the weighing scale 3 reaches the appropriate weight, the traction rope 12 is wrapped around the surface of the electric drum 11. The electric drum 11 is started and rotates. The traction rope 12 is detached from the surface of the electric drum 11 and becomes longer. Due to gravity, the weighing box 2 rotates downward with the hinge as the fulcrum, and the tea leaves in the weighing box 2 can be poured out. The weighed tea leaves can be poured out directly.
