Description

Technical Field

[0001] The present invention relates to the technical field of tea processing, and in particular to a feeding device for a tea color sorter. Background Art

[0002] A color sorter is a device that automatically sorts out different-colored particles in granular materials based on the differences in the optical properties of the materials, using optoelectronic detection technology. At present, color sorters are widely used in the tea processing production process to replace traditional manual operations for selecting different grades of tea.

[0003] Some teas such as raw Pu-erh tea and Dahongpao are prone to agglomeration, and direct feeding affects the color sorting effect. The tea needs to be first sorted out by a carding machine and small fragments in the tea are removed, and then enter a shaking sieve machine. The shaking sieve machine shakes the tea loose and removes the fine foam in the tea, and then enters a hoist. The hoist lifts the tea to a vibrating sieve on the main machine. The vibrating sieve shakes the tea loose again and evenly distributes it into each channel for color sorting. The existing feeding device for a tea color sorter has the problem that it cannot effectively disperse the tea when in use. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies existing in the prior art, and a feeding device for a tea color sorter is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A feeding device for a tea color sorter, comprising a feeding housing, and a blanking opening is formed at the bottom of one side of the feeding housing; further comprising a crawler feeding mechanism for feeding the tea discharged from the opening of the blanking opening. The inner walls on both sides of the feeding housing are provided with vertically arranged inner walls and inclined inner walls which are arranged alternately, and the vertical inner wall and the inclined inner wall form a stepped inner wall of the feeding housing; an arc-shaped transition member is installed inside the feeding housing, and the outer arc surface of the transition member is on the side close to the opening of the feeding housing, and there is a gap between both sides of the transition member and the stepped inner wall of the feeding housing; a blowing mechanism is arranged on the inner wall of the feeding housing for blowing the tea that slides to the side of the vertical inner wall; the blowing mechanism comprises a cavity formed on the inner wall of the feeding housing, the cavity is located at the bottom of the transition member, and blowing holes are formed on the side surface of the cavity; further comprising an air pump for blowing air into the cavity; a plurality of sequentially connected limiting mesh plates are installed at the bottom of the transition member for limiting the tea that slides to the side of the vertical inner wall and is blown up; a buffer inner arc surface is arranged on the side of the limiting mesh plate close to the vertical inner wall, and the opening position of the blowing hole corresponds to the position of the buffer inner arc surface for guiding the tea blown to the side of the limiting mesh plate onto the inclined inner wall; an inclined blanking mesh plate is arranged at the bottom inside the feeding housing, and a blanking transition member is installed on one side of the blanking mesh plate extending outside the feeding housing through the blanking opening for blanking the tea in the feeding housing onto the crawler feeding mechanism.

[0007] Preferably, a flexible dispersion member is arranged at the top of the limiting mesh plate, and one end of the flexible dispersion member extends to the buffer inner arc surface for buffering the tea blown to the side of the limiting mesh plate.

[0008] Preferably, a mounting seat is installed inside the feeding housing, and the top of the mounting seat is connected to the inner arc surface of the transition member through a spring; a vibration member is installed on the inner arc surface of the transition member for driving the transition member and the limiting mesh plate to vibrate.

[0009] Preferably, an extending mechanism is arranged at the top of the transition member for increasing the contact area with the tea; the extending mechanism comprises an extension rod installed at the top of the transition member, the extension rod is located on the side close to the stepped inner wall of the feeding housing, and extension wings are installed on the side surface of the extension rod.

[0010] Preferably, a waste discharging opening is formed on the side of the feeding housing away from the blanking opening, a slag discharging plate is movably installed at the bottom of the blanking mesh plate, and one end of the slag discharging plate away from the blanking mesh plate extends outside the feeding housing through the waste discharging opening for transferring the impurities screened by the blanking mesh plate to the outside of the feeding housing.

[0011] Preferably, a knocking mechanism is further included for reciprocally knocking the bottom of the blanking mesh plate; one end of the blanking mesh plate located inside the feeding housing is slidably connected to the inner wall of the feeding housing.

[0014] The beneficial effects of the present invention are as follows:

[0015] During use, the tea to be fed into the color sorter is fed onto the transition component. The tea slides down the outer arc surface at the top of the transition component onto the stepped inner wall of the feeding housing. When the tea slides down the stepped inner wall, the air pump blows air into the cavity. When the tea slides from the inclined inner wall to the side of the vertical inner wall, the airflow ejected from the air blowing holes blows the falling tea to promote the dispersion of the tea. At the same time, the limiting mesh plate limits the blown tea and guides the tea that is blown into the buffer inner arc surface of the limiting mesh plate onto the inclined inner wall, ensuring that the tea can slide and be blown sequentially on the stepped inner wall of the feeding housing, effectively dispersing the tea. After the dispersion is completed, the tea falls onto the blanking mesh plate and drops from the opening of the blanking port onto the crawler feeding mechanism. The crawler feeding mechanism transports the tea into the color sorter, ensuring that the tea can be effectively dispersed when being fed into the color sorter. Description of the Drawings

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figures 1 to 3 , a feeding device for a tea color sorter, comprising a feeding shell 1, a feeding port 9 is provided at the bottom of one side of the feeding shell 1; further comprising a crawler feeding mechanism 10 for feeding tea discharged at the opening of the feeding port 9, the inner walls on both sides of the feeding shell 1 are provided with vertical inner walls 7 and inclined inner walls 8 arranged alternately, and the vertical inner walls 7 and the inclined inner walls 8 constitute the stepped inner walls of the feeding shell 1; a transition component 2 of an arc structure is installed inside the feeding shell 1, the outer arc surface of the transition component 2 is the side close to the opening of the feeding shell 1, and a gap is left between the two sides of the transition component 2 and the stepped inner wall of the feeding shell 1; a blowing mechanism 15 is provided on the inner wall of the feeding shell 1, for blowing tea that slides down to the side of the vertical inner wall 7; the blowing mechanism 15 comprises a cavity 153 provided on the inner wall of the feeding shell 1, and the cavity 1 53 is located at the bottom of the transition component 2, and a blowing hole 152 is provided on the side of the cavity 153; it also includes an air pump 151 for blowing air into the cavity 153; the bottom of the transition component 2 is equipped with a plurality of limiting mesh plates 14 connected in sequence, which are used to limit the tea leaves that slide to the side of the vertical inner wall 7 and are blown up; the limiting mesh plate 14 is provided with a buffer inner arc surface 19 on the side close to the vertical inner wall 7, and the opening position of the blowing hole 152 corresponds to the position of the buffer inner arc surface 19, which is used to guide the tea leaves blown to the side of the limiting mesh plate 14 to the inclined inner wall 8; the bottom of the interior of the loading shell 1 is provided with an inclined unloading mesh plate 11, and the unloading mesh plate 11 extends through the unloading port 9 to the side outside the loading shell 1, and a unloading transition component 17 is installed, which is used to unload the tea leaves in the loading shell 1 to the crawler feeding mechanism 10.

[0022] When in use, the tea leaves to be loaded into the color sorter are loaded onto the transition component 2, and the tea leaves slide down the outer arc surface at the top of the transition component 2 to the stepped inner wall of the loading shell 1. When the tea leaves slide down the stepped inner wall, the air pump 151 blows air into the cavity 153. When the tea leaves slide down from the inclined inner wall 8 to the side of the vertical inner wall 7, the air flow ejected from the blowing hole 152 blows the fallen tea leaves to promote the dispersion of the tea leaves. At the same time, the limiting mesh plate 14 limits the blown tea leaves, and guides the tea leaves blown into the buffer inner arc surface 19 of the limiting mesh plate 14 to the inclined inner wall 8, ensuring that the tea leaves can slide and blow in sequence on the stepped inner wall of the loading shell 1, so as to effectively disperse the tea leaves. After dispersion, the tea leaves fall on the unloading mesh plate 11 and fall from the opening of the unloading port 9 to the crawler feeding mechanism 10. The crawler feeding mechanism 10 transports the tea leaves to the color sorter, ensuring that the tea leaves can be effectively dispersed when they are loaded into the color sorter.

[0023] As a preferred embodiment of the present invention, a flexible dispersion member 6 is provided at the top of the limit mesh plate 14. One end of the flexible dispersion member 6 extends to the buffer inner arc surface 19, which is used to buffer the tea leaves blown to the side of the limit mesh plate 14. The flexible dispersion member 6 contacts the blown-up tea leaves, which can effectively disperse the agglomerated tea leaves and also buffer and decelerate the tea leaves, avoiding the situation where the tea leaves are blown up and collide with the side of the limit mesh plate 14 at high speed, resulting in the fragmentation of the tea leaves.

[0024] As a preferred embodiment of the present invention, the flexible dispersion member 6 is made of materials such as rubber and silica gel. In this embodiment, the preferred flexible dispersion member 6 is made of rubber.

[0025] As a preferred embodiment of the present invention, a mounting seat 5 is installed inside the feeding housing 1. The top of the mounting seat 5 is connected to the inner arc surface of the transition member 2 through a spring; a vibration member 3 is installed on the inner arc surface of the transition member 2, which is used to drive the transition member 2 and the limit mesh plate 14 to vibrate, promoting the tea leaves fed onto the transition member 2 to effectively slide into the gap between the transition member 2 and the inner wall of the feeding housing 1, and also promoting the tea leaves blown to the buffer inner arc surface 19 to effectively slide onto the inclined inner wall 8.

The extension rod 161 is located on the side close to the stepped inner wall of the feeding housing 1. An extension wing 162 is installed on the side of the extension rod 161. During the process of the vibration member 3 driving the transition member 2 to vibrate, the extension rod 161 and the extension wing 162 increase the contact area with the tea leaves stacked on the transition member 2, promoting the tea leaves on the transition member 2 to effectively vibrate and fall, and avoiding the blockage of the gap between the transition member 2 and the stepped inner wall of the feeding housing 1.

[0027] As a preferred embodiment of the present invention, both the extension rod 161 and the extension wing 162 are made of silica gel.

[0028] As a preferred embodiment of the present invention, a waste discharge port 12 is opened on one side of the feeding housing 1 away from the discharge port 9. A slag discharge plate 18 is movably installed at the bottom of the discharge mesh plate 11. One end of the slag discharge plate 18 away from the discharge mesh plate 11 extends to the outside of the feeding housing 1 through the waste discharge port 12, which is used to transfer the impurities screened by the discharge mesh plate 11 to the outside of the feeding housing 1.

[0030] As a preferred embodiment of the present invention, the knocking mechanism 13 includes a cam 131 movably installed inside the feeding housing 1, and further includes a driving component 132 for driving the cam 131 to rotate. The cam 131 can be driven by the driving component 132 to rotate, and the cam 131 reciprocally knocks on the bottom of the blanking mesh plate 11. The blanking mesh plate 11 reciprocally lifts and vibrates under the knocking action of the cam 131 and the action of gravity, ensuring that the tea leaves falling on the blanking mesh plate 11 can be effectively dispersed and screened.

[0031] As a preferred embodiment of the present invention, the track feeding mechanism 10 includes a mounting housing 102. A conveyor track 103 is movably arranged inside the mounting housing 102. Spacing components 101 are installed on the side of the conveyor track 103 at intervals. The tea leaves discharged at the blanking port 9 fall on the conveyor track 103, and the spacing components 101 separate the tea leaves on the conveyor track 103, ensuring that the tea leaves can be evenly distributed on the conveyor track 103.

[0032] During use, the tea leaves to be fed into the color sorter are fed onto the transition component 2. The tea leaves slide down the outer arc surface at the top of the transition component 2 to the stepped inner wall of the feeding housing 1. When the tea leaves slide on the stepped inner wall, the air pump 151 blows air into the cavity 153. When the tea leaves slide from the inclined inner wall 8 to the side of the vertical inner wall 7, the airflow ejected from the air blowing holes 152 blows the falling tea leaves to promote the dispersion of the tea leaves. At the same time, the limiting mesh plate 14 limits the blown tea leaves, and guides the tea leaves blown into the buffer inner arc surface 19 of the limiting mesh plate 14 to the inclined inner wall 8, ensuring that the tea leaves can slide and be blown in sequence on the stepped inner wall of the feeding housing 1, effectively dispersing the tea leaves. After the dispersion is completed, the tea leaves fall on the blanking mesh plate 11 and fall from the opening of the blanking port 9 onto the track feeding mechanism 10. The track feeding mechanism 10 transports the tea leaves into the color sorter, ensuring that the tea leaves can be effectively dispersed when being fed into the color sorter; the flexible dispersion component 6 contacts the blown-up tea leaves, can effectively disperse the agglomerated tea leaves, and can also buffer and decelerate the tea leaves, avoiding the situation where the tea leaves are blown up and collide with the side of the limiting mesh plate 14 at high speed, causing the tea leaves to break; during the process of the vibration component 3 driving the transition component 2 to vibrate, the extension rod 161 and the extension wing 162 increase the contact area with the tea leaves stacked on the transition component 2, promoting the effective vibration and discharging of the tea leaves on the transition component 2, and avoiding the blockage of the gap between the transition component 2 and the stepped inner wall of the feeding housing 1; the cam 131 can be driven by the driving component 132 to rotate, and the cam 131 reciprocally knocks on the bottom of the blanking mesh plate 11. The blanking mesh plate 11 reciprocally lifts and vibrates under the knocking action of the cam 131 and the action of gravity, ensuring that the tea leaves falling on the blanking mesh plate 11 can be effectively dispersed and screened.
