Referring to fig. 1-6, a tea leaf rolling machine comprises a base 1, a support rod 2 is fixedly installed in the middle of the base 1, a driving motor 3 is fixedly installed in the base 1 and located on one side of the support rod 2, a rotary drum 4 is movably sleeved on the outer ring of the support rod 2, a driving shaft at the top of the driving motor 3 is fixedly connected with a driving gear 6 meshed with an outer ring gear at the bottom of the rotary drum 4, a rolling disc 7 is fixedly sleeved on the outer ring of the rotary drum 4, a discharging block 11 is fixedly installed at the middle ring position on one side of the rolling disc 7, supporting rollers 5 with the top contacting with the rolling disc 7 are uniformly and movably installed on the outer ring at the top of the base 1, a top frame 8 is fixedly installed at the top of the support rod 2, supporting frames 9 are symmetrically and fixedly connected at the bottoms of two sides of the top frame 8, a rolling barrel 10 is fixedly installed in the middle of the supporting frame 9, a transmission cavity 801 is formed in the top frame 8, gear sleeve shafts 12 are symmetrically and movably installed at two sides of the transmission cavity 801, two transmission gears 15 which are sequentially meshed with each other are movably arranged between the gear sleeve shaft 12 and the outer ring of the rotary drum 4 in the transmission cavity 801, the rotation direction transmitted from the rotary drum 4 can be changed through the two transmission gears 15, so that the rotation direction of the rotary shaft 13 in the kneading barrel 10 is driven to be opposite to the rotation direction of the kneading disc 7, tea leaves in the kneading barrel 10 are driven to rotate in a certain direction in the rotary shaft 13 and opposite to the rotation of the kneading disc 7, the kneading effect is better, the rotary shaft 13 is movably sleeved in the gear sleeve shaft 12, the bottom of the rotary shaft 13 extends into the kneading barrel 10, the outer ring movable sleeve machine of the rotary shaft 13 at the position of the kneading barrel 10 is provided with a pressure plate 14, a through hole 1301 is formed in the rotary shaft 13, a groove 1302 is formed in one side of the outer ring of the rotary shaft 13, a limit ring 18 is fixedly sleeved at the bottom of the groove 1302, an air hole 1303 which is communicated with the through hole 1301 is formed in the position of the outer ring of the rotary shaft 13, an annular cavity 1401 is arranged in the middle of the pressure plate 14, sliding grooves 1402 are uniformly arranged between the inner wall of the pressure plate 14 and the annular cavity 1401, ejector blocks 16 are movably sleeved at the outer ends of the sliding grooves 1402, and springs 17 are fixedly connected between the ejector blocks 16 and the inner ends of the sliding grooves 1402.

Wherein, the rotating shaft 13 and the gear sleeve shaft 12 are in limiting sleeve joint by a clamping groove, the top cap of the rotating shaft 13 is positioned at the top of the top frame 8, so that the gear sleeve shaft 12 is not driven to be more beneficial to the discharging and charging of the kneading barrel 10 when the rotating shaft 13 is pulled upwards, meanwhile, the rotation shaft 13 and the gear sleeve shaft 12 can be driven to synchronously rotate by utilizing the limit of the clamping groove during rotation without adding an additional driving structure, the two ends of the length of the groove 1302 are the highest working position and the lowest working position of the pressure plate 14 in the kneading barrel 10, the pressure plate 14 is made of high-density smooth materials, the pressure plate 14 plays a stable downward pressure in the kneading barrel 10 to ensure that tea leaves in the kneading barrel 10 are kneaded under a certain pressure, meanwhile, the length of the groove 1302 also limits the range of the amount of the rolled tea leaves of the rolling barrel 10, thereby avoiding the occurrence of poor rolling effect, and it is also ensured that friction with the inner wall of the kneading tub 10 is as small as possible during the pressing of the pressing plate 14.

Wherein, the distribution density of gas pocket 1303 diminishes downwards and the aperture diameter diminishes equally along vertical direction, the internal air is many when just beginning to knead and push down tealeaves, and it is severe to push down at the top, so the gas pocket 1303 that is close to the top is more favorable to the pushing down and the exhaust of pressure disk 14, along with pushing down and kneading tealeaves volume and diminishing, there is not air escape this moment, gas pocket 1303 mainly plays radiating effect, the through-hole 1301 top is communicated to the pivot 13 outside of higher than kneading barrel 10 department, guaranteed that will knead the inside gaseous outside of coming out of barrel 10, wherein contain heat and steam can not be in the tealeaves that contacts kneading the barrel 10.

Wherein, the resultant extrusion force of the top block 16 on the pressure plate 14 is larger than the gravity thereof when the top block 16 does not push the groove 1302, the resultant extrusion force of the top block 16 on the pressure plate 14 is smaller than the gravity thereof when the top block 16 pushes the groove 1302, a plurality of top blocks 16 are adopted to be propped against the rotating shaft 13 under the action of the spring 17, the pressing plate 14 can be pressed down according to the variation of the pressing force against the rotating shaft 13 and the gravity thereof, thereby ensuring that the pressing down can be realized when the tea is kneaded, ensuring that the tea in the kneading barrel 10 is subjected to a stable pressure, meanwhile, when the rotating shaft 13 rotates, the pressure plate 14 is intermittently controlled to slide downwards, so that a certain protection effect can be achieved, the pressure plate 14 is prevented from being pressed to the bottom at one time, and the pressure variation between the platen 14 and the top block 16 makes the distance of each slide down very short, this ensures that the rapidly rotating spindle 13 with the lower pressure plate 14 is not affected too much.

The working principle is that the rotating shaft 13 is firstly upwards drawn out to drive the pressing disc 14 to be upwards lifted until the pressing disc 14 is separated from the top position of the kneading barrel 10, then tea leaves are filled into the kneading barrel 10, then the rotating shaft 13 is downwards placed to be inserted into the bottommost part, at the moment, the top block 16 inside the pressing disc 14 is not abutted to the groove 1302, the pressing disc 14 is positioned at the topmost position, then the driving motor 3 is started, the driving motor 3 drives the driving gear 6 to rotate, then the driving gear 6 drives the rotating drum 4 to rotate, the kneading disc 7 is driven to rotate when the rotating drum 4 rotates, the top part of the rotating drum 4 drives the gear sleeve shaft 12 to rotate through the transmission gear 15 in the transmission cavity 801, the gear sleeve shaft 12 rotates to drive the rotating shaft 13 to rotate, the tea leaves inside the kneading barrel 10 can be driven to have a certain rotation trend when the rotating shaft 13 rotates, and the direction of the tea leaves is opposite to the rotation direction of the kneading disc 7,

along with the reduction of the volume of the tea leaves in the rolling barrel 10 during rolling, the top block 16 is intermittently contacted with the groove 1302 when the rotating shaft 13 rotates, so that the braking force of the pressure plate 14 is increased for a while and reduced for a while, and the pressure plate 14 can be pressed down due to large mass, so that the gravity of the pressure plate 14 is utilized to play a stable pressure role, meanwhile, the air in the rolling barrel 10 can be discharged from the air hole 1303 through the through hole 1301 during pressing down, and heat and water vapor generated during rolling can be discharged from the air hole 1303, so that the rolling effect is better, the discharging block 11 is opened after rolling, and the rolled tea leaves are discharged from the bottom.
