Description

Anji white tea tea hair removal device

Technical Field

The utility model belongs to the technical field of tea processing, and particularly relates to a device for removing tea hairs from Anji white tea.

Background Art

Color sorters are devices that automatically sort out particles of different colors from granular materials using photoelectric detection technology based on differences in the optical properties of the materials. At present, color sorters are widely used in the tea processing and production process, replacing traditional manual labor to select tea of different grades.

The tea color sorting machine is a machine that utilizes the color, shape and size differences between tea stems, yellow flakes and genuine tea leaves, and uses a high-definition CCD optical sensor to classify and select tea leaves, thereby improving the quality and added value of tea leaves. However, small objects such as tea hairs cannot be removed. The tea hairs of Anji white tea have no utilization value and will be mixed with the tea leaves during the processing, so they need to be removed. Before the existing Anji white tea is color sorted, it is necessary to use an additional wind separator to remove the tea hairs. After the removal of the tea hairs is completed, the color sorting operation can be performed. This method of removing the tea hairs requires additional equipment for removing the tea hairs, which increases the floor space and is not conducive to production cost control.

In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

1 to 4, the utility model provides a device for removing tea hair from Anji white tea, comprising:

The vibrating conveying mechanism comprises a conveying plate 1 and a supporting frame 2. The conveying plate 1 is arranged obliquely. A vibrating assembly is arranged between the conveying plate 1 and the supporting frame 2. The lower end of the conveying plate 1 is arranged above the conveying belt of the color sorter.

The negative pressure adsorption mechanism includes a negative pressure fan 3, which is arranged on the ground through a height adjustment component. The top of the negative pressure fan 3 is an air outlet, the air outlet is connected to one end of a telescopic pipe, and the other end of the telescopic pipe is connected to a tea hair collection device. The bottom of the negative pressure fan 3 is an air inlet, and the lower end of the conveying plate 1 is arranged below the air inlet of the negative pressure fan 3.

The main function of the conveying plate 1 is to convey the Anji white tea to the bottom of the air inlet of the negative pressure fan 3 and make the Anji white tea fall onto the conveyor belt of the color sorter; the main function of the vibration component is to vibrate the conveying plate 1, thereby accelerating the movement of the Anji white tea on the conveying plate 1, and shaking off the tea hairs adhering to the tea leaves during the movement, so as to facilitate the subsequent tea hair removal process; the main function of the negative pressure fan 3 is to create a certain negative pressure environment at the lower end of the conveying plate 1 to absorb the lighter tea hairs; the main function of the telescopic pipe is to guide the absorbed tea hairs into the tea hair collection device; the main function of the height adjustment component is to adjust the distance between the negative pressure fan 3 and the lower end of the conveying plate 1 to ensure the best tea hair removal effect. On the whole, the utility model can use negative pressure to absorb the tea hairs in the falling tea leaves while putting Anji white tea onto the conveyor belt of the color sorter, so as to achieve the purpose of removing the tea hairs. Compared with wind selection removal, this method of removing tea hairs can improve the removal effect by 25%, which is beneficial to the accuracy of subsequent color sorting. At the same time, color sorting and tea hair removal can be carried out at the same time, which improves work efficiency and reduces the use of equipment.

A further optimized solution further includes a controller (not shown in the figure), which is electrically connected to the vibration component and the height adjustment component. The controller can control the working state of the vibration component and the height adjustment component.

A further optimized solution is that the height adjustment component includes a plurality of fixed columns 4 fixedly connected to the ground, the tops of the plurality of fixed columns 4 are respectively vertically slidably connected with telescopic columns 5, a fixed frame 6 is fixedly connected between the plurality of telescopic columns 5, the negative pressure fan 3 is fixedly connected to the fixed frame 6, and an adjustment drive member is arranged between the fixed columns 4 and the telescopic columns 5.

A further optimized solution is that the adjusting drive component includes a slide rail 7 vertically fixedly connected to the side wall of the fixed column 4, a transmission plate 9 is vertically slidably connected in the slide rail 7, the transmission plate 9 is fixedly connected to the side wall of the telescopic column 5, a screw rod 8 is rotatably connected in the slide rail 7, one end of the screw rod 8 is transmission-connected to the first motor 10, and the first motor 10 is fixedly connected to the slide rail 7.

As shown in Figures 1 and 2, a group of telescopic columns 5 are fixedly connected to each of the four corners at the bottom of the fixed frame 6. Adjustment drive members are provided on the two diagonal groups of fixed columns 4. Specifically, when it is necessary to lower the height of the negative pressure fan 3 to improve the effect of removing tea hair, the two groups of first motors 10 can be controlled by the controller to rotate, and the rotation of the first motor 10 drives the screw rod 8 to rotate. When the screw rod 8 rotates, it drives the transmission plate 9 to move downward along the slide rail 7 through the bolt transmission, so that the telescopic column 5 descends in the fixed column 4, driving the fixed frame 6 to descend, and finally realizing the height reduction of the negative pressure fan 3. When it is necessary to increase the height of the negative pressure fan 3, the two groups of first motors 10 can be controlled to rotate in the opposite direction.

According to a further optimized solution, a large opening end of the wind collecting hood 11 is fixedly connected to the fixed frame 6 , and an air inlet of the negative pressure fan 3 is fixedly connected to a small opening end of the wind collecting hood 11 .

As shown in FIG. 1 , by providing an air collecting hood 11 , the negative pressure effect created by the negative pressure fan 3 can be enhanced, and the ability of the negative pressure fan 3 to remove tea hairs can be improved.

A further optimized solution is that the vibration assembly includes a plurality of lower connecting seats 19 fixedly connected to two opposite side walls of the support frame 2 and an upper connecting seat 20 fixedly connected to two opposite side walls of the conveying plate 1, support springs 14 are respectively fixedly connected between the plurality of lower connecting seats 19 and the plurality of upper connecting seats 20, and a vibration generating member is arranged between the conveying plate 1 and the support frame 2.

A further optimized solution is that the vibration generating component includes a second motor 16 fixedly connected to the support frame 2, a rotating wheel 17 is fixedly sleeved on the output shaft of the second motor 16, one end of a connecting rod 18 is hinged to the edge of the rotating wheel 17, and a connecting plate 15 is fixedly connected to the bottom of the conveying plate 1, and the other end of the connecting rod 18 is hinged to the connecting plate 15.

As shown in FIG4 , the support frame 2 is fixedly connected to the ground, and the support spring 14 allows the conveying plate 1 to vibrate on the support frame 2. When working, the second motor 16 is controlled to rotate by the controller, and the rotation of the second motor 16 drives the rotating wheel 17 to rotate. Since the two ends of the connecting rod 18 are respectively hinged on the edge of the rotating wheel 17 and the connecting plate 15, the rotating wheel 17 will reciprocate the connecting plate 15 through the connecting rod 18 when rotating, so that the conveying plate 1 vibrates on the support frame 2. When the Anji white tea moves on the conveying plate 1 toward the color sorter, the tea hairs adhering to the tea leaves are shaken off, so as to facilitate the subsequent negative pressure hair removal work.

A further optimized solution is that the telescopic pipe fitting includes a bottom pipe 12 and a fixed pipe 13. The bottom pipe 12 is vertically fixedly connected to the air outlet of the negative pressure fan 3, one end of the fixed pipe 13 is slidably mounted on the bottom pipe 12, and the other end of the fixed pipe 13 is connected to the tea hair collection device.

As shown in Figure 3, the bottom tube 12 can slide up and down in the fixed tube 13, thereby ensuring that while the negative pressure fan 3 moves up and down with the fixed frame 6, the connection between the bottom tube 12 and the fixed tube 13 is sealed, so that the tea leaves sucked away by the negative pressure fan 3 can enter the tea leaves collection device.

To further optimize the solution, the tea hair collection device can be configured as a collection box or a collection bag, which is placed outside the processing plant to temporarily store the removed tea hair.

The working process of this embodiment is as follows: the operator starts the color sorter and starts the first motor 10 and the second motor 16 through the controller. The Anji white tea to be color sorted is placed on the high end of the conveying plate 1. When the conveying plate 1 vibrates, the Anji white tea moves to the low end and shakes off the tea hairs adhering to the tea leaves. When the Anji white tea moves to the low end of the conveying plate 1 and falls downward, the tea hairs are sucked upward in the negative pressure environment created by the negative pressure fan 3 due to their light weight, and enter the tea hair collection device through the bottom pipe 12 and the fixed pipe 13. Due to their heavy weight, the Anji white tea falls onto the conveying belt of the color sorter under the action of gravity and is transported to the color sorter through the conveying belt for color sorting.
