[0030] The uniform feeding mechanism includes a first slide bar 6, a second slide bar 7, a sliding seat 8, a screw rod 13, a first fixed seat 9, a second fixed seat 10, a first motor 12, and a screw nut 11. The first slide bar 6 and the second slide bar 7 are parallel to each other and are arranged on the front and rear sides of the frame 1. The length direction of the first slide bar 6 and the second slide bar 7 is parallel to the width direction of the lower tea-rubbing conveyor belt 4. The bottom of the lower tea-rubbing frame 2 is fixedly connected with the sliding seat 8, and the sliding seat 8 is slidably matched with the first slide bar 6 and the second slide bar 7. The frame 1 is fixedly connected with the first fixed seat 9, the lower tea-rubbing frame 2 is fixedly connected with the second fixed seat 10, and the second fixed seat 10 is fixedly connected with the screw rod 13. The length direction of the screw rod 13 is parallel to the length direction of the first slide bar 6. The screw rod 13 is threadedly matched with the screw nut 11. The first motor 12 is fixedly connected to the first fixed seat 9, and the first motor 12 is connected to the screw nut 11 and the first motor 12 can drive the screw nut 11 to rotate forward and reverse.

[0031] By setting up the uniform feeding mechanism, when in use, the first motor 12 drives the lead screw nut 11 to rotate alternately forward and reverse, so that the lead screw 13 in the lead screw nut 11 reciprocates left and right, and the lead screw 13 drives the lower tea-rolling frame 2 to reciprocate left and right along the first slide bar 6 and the second slide bar 7 through the second fixed seat 10, and the tea leaves falling on the lower tea-rolling conveyor belt 4 are evenly spread left and right, thereby ensuring that the tea leaves are not easily piled up and the quality of the tea leaves after rolling is uniform.

[0034] The thickness of the upper tea-rubbing conveyor belt 5 and the lower tea-rubbing conveyor belt 4 is between 3 mm and 7 mm, and the material of the upper tea-rubbing conveyor belt 5 and the lower tea-rubbing conveyor belt 4 is set to silica gel.

[0035] In some embodiments, Figure 5-6 As shown, it also includes a spacing adjustment mechanism for adjusting the spacing between the upper tea-rubbing conveyor belt 5 and the lower tea-rubbing conveyor belt 4 to adapt to the needs of rubbing tea with different thicknesses. The spacing adjustment mechanism includes a screw 16, a through hole 17, a screw hole 18, a spring 15, and a knob 14. Two through holes 17 are symmetrically provided on the left and right sides of the upper tea-rubbing rack 3, and the two through holes 17 on each side are respectively arranged on the front and rear sides of the upper tea-rubbing rack 3. The lower tea-rubbing rack 2 is provided with screw holes 18 corresponding to the through holes 17 one by one. A screw rod 16 is provided in each through hole 17. The screw rod 16 passes through the through hole 17 and is threadedly engaged in the screw hole 18. The top end of the screw rod 16 is fixedly connected with a knob 14. A spring 15 is sleeved on each screw 16. The spring 15 is provided between the upper tea-rubbing rack 3 and the lower tea-rubbing rack 2. The bottom end of the spring 15 is fixedly connected to the lower tea-rubbing rack 2, and the top end of the spring 15 is fixedly connected to the upper tea-rubbing rack 3. The spring 15 can keep the upper tea-rubbing rack 3 and the knob 14 in a state of mutual conflict.

[0036] By setting the spacing adjustment mechanism, by synchronously turning the four knobs 14, the screw 16 can be driven to rotate, thereby driving the height of the knob 14 to rise and fall, and under the action of the spring 15, the lower tea-rubbing rack 2 conflicts with the bottom of the knob 14, so that the height of the entire upper tea-rubbing rack 3 is adjusted, thereby adjusting the spacing between the upper tea-rubbing conveyor belt 5 and the lower tea-rubbing conveyor belt 4, and by rotating the two front knobs 14 or the two rear knobs 14 separately, the angle of the upper tea-rubbing rack 3 can be adjusted, which can be applicable to tea leaves of various coarsenesses and finenesses, and has a good use effect.

[0037] In some embodiments, Figure 7As shown, the upper tea-rubbing conveyor belt 5 and the lower tea-rubbing conveyor belt 4 are provided with a plurality of oblique guide strips, the oblique guide strips including an outer oblique strip 19, a first middle strip airbag 20, a second middle strip airbag 21, and an inflation port 22. The first middle strip airbag 20 and the second middle strip airbag 21 are both arranged in a V shape, and the first middle strip airbag 20 and the second middle strip airbag 21 are symmetrically arranged to form a rhombus, and the rhombus is arranged in the middle of the conveyor belt, and the inflation port 22 is fixedly connected to the first middle strip airbag 20 and the second In the middle of the middle strip airbag 21, outer oblique strips 19 are provided on both sides of the rhombus formed by the first middle strip airbag 20 and the second middle strip airbag 21. When the first middle strip airbag 20 is inflated and the second middle strip airbag 21 is not inflated, the first middle strip airbag 20 bulges and forms a V shape with the outer oblique strips 19 on both sides. When the first middle strip airbag 20 is not inflated and the second middle strip airbag 21 is inflated, the second middle strip airbag 21 bulges and forms a W shape with the outer oblique strips 19 on both sides.

[0038] By setting the inclined guide strips, the pattern of the inclined guide strips can be adjusted according to the amplitude of the left and right shaking of the uniform feeding mechanism. When the amount of tea leaves falling is small, the lower tea-rubbing rack 2 can be completely spread out by a small amplitude of the left and right shaking, and the tea leaves will be scattered in the middle of the lower tea-rubbing conveyor belt 4. At this time, the first middle strip airbag 20 is inflated. When the first middle strip airbag 20 is inflated and the second middle strip airbag 21 is not inflated, the first middle strip airbag 20 bulges to form a V shape with the outer inclined strips 19 on both sides. When the amount of tea leaves falling is large, the lower tea-rubbing rack 2 can be completely spread out. The tea leaves will be scattered in the middle of the lower tea-rubbing conveyor belt 4. When the lower tea-rubbing rack 2 is large, the amplitude of left-right shaking is large to fully spread the tea leaves, and the tea leaves will be scattered in the entire width direction of the lower tea-rubbing conveyor belt 4. At this time, the second middle strip air bag 21 is inflated. When the first middle strip air bag 20 is not inflated and the second middle strip air bag 21 is inflated, the second middle strip air bag 21 bulges to form a W shape with the outer oblique strips 19 on both sides, so that the appropriate texture can be selected according to the output and the amplitude of left-right shaking to ensure that the oblique guide strips make the tea leaves bend and wrinkle and roll up into strips at the same time.

[0039] The first middle strip airbag 20, the second middle strip airbag 21 and the outer oblique strip 19 are all embedded in the conveyor belt, and the inflation port 22 extends to the outer surface of the conveyor belt.

[0040] Working principle: through the setting of the uniform feeding mechanism, when in use, the first motor 12 drives the lead screw nut 11 to rotate alternately forward and reverse, so that the lead screw 13 in the lead screw nut 11 reciprocates left and right, and the lead screw 13 drives the lower tea-rubbing frame 2 to reciprocate left and right along the first slide bar 6 and the second slide bar 7 through the second fixed seat 10, and the tea leaves falling on the lower tea-rubbing conveyor belt 4 are evenly spread left and right, thereby ensuring that the tea leaves are not easy to accumulate and ensuring the uniform quality of the tea leaves after rubbing.
