Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of tea processing and kneading devices, and in particular to a tea processing and kneading device. Background Technology
[0002] A disc-type tea rolling machine has a flat rolling disc supported on a base. The disc surface is evenly equipped with several arc-shaped raised ribs. Driven by a crank-connecting rod mechanism, the rolling drum rotates eccentrically horizontally relative to the rolling disc on the disc surface. This causes the tea leaves inside the rolling drum to continuously tumble with the movement of the drum. Through a pressure device applying pressure to the tea leaves and the kneading action of the ribs on the rolling disc, the leaves are rolled into strips and tea juice is squeezed out. Large-scale tea rolling machines employ a structure where the rolling drum and rolling disc rotate simultaneously in opposite directions; this is called a double-action tea rolling machine. Machines where the rolling disc does not rotate are called single-action tea rolling machines. Machines where the rolling drum cover also rotates are called triple-action tea rolling machines.
[0003] The inventor discovered during routine use of a disc kneading machine that when tea leaves are kneaded, some tea fragments are inevitably produced, resulting in the presence of fragments in the kneaded tea. Since the kneading disc of the machine is not equipped with a sieving component, this leads to a decline in the quality of the tea, thus causing problems. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a tea processing and kneading device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a tea processing kneading device, comprising a support frame, a motor fixedly connected inside the support frame, a crank connecting rod provided at the top of the support frame, the crank connecting rods being rotatably connected to each other, a kneading drum rotatably connected to one end of the crank connecting rod, an adjusting component provided at the top of the kneading drum, the adjusting component comprising a threaded rod, an adjusting rod threadedly connected to the surface of the threaded rod, a kneading block fixedly connected to one end of the adjusting rod, the kneading block being disposed inside the kneading drum, a kneading disc provided at the top of the support frame, a material discharge frame provided inside the support frame, a sieving device provided inside the material discharge frame, a fixing device provided on the side of the material discharge frame, the sieving device comprising a rectangular groove opened inside the material discharge frame, and a screen provided inside the rectangular groove.
[0006] The aforementioned components achieve the following effects: under the action of the sieve, the internal debris of the tea leaves is screened off, thus achieving the function of sieving. When it is necessary to knead the tea leaves, the withered tea leaves are placed on the surface of the kneading disc, the motor is started, and the crank connecting rod rotates through the coupling at the output end of the motor. This causes the kneading drum driven by the crank connecting rod mechanism to perform an eccentric horizontal rotation relative to the kneading disc on the disc surface. The tea leaves inside the kneading drum are continuously turned over with the movement of the kneading drum. Through the pressure device, the tea leaves are pressed, and the kneading action of the ribs on the kneading disc causes the leaves to roll into strips and squeeze out tea juice, thus achieving the function of kneading.
[0007] Preferably, a washer, which is a rubber ring, is fixedly connected to the inner wall of the rectangular groove.
[0008] The effect achieved by the above components is that, under the action of the gasket, the screen will not directly contact the rectangular groove, thus achieving a rigid contact phenomenon.
[0009] Preferably, a round rod is fixedly connected to the inner wall of the rectangular groove, and a retaining ring, which is a rubber ring, is fixedly connected to the surface of the round rod.
[0010] The effect achieved by the above components is that, under the action of the round rod and the retaining ring, the screen will not slip out of the inside of the rectangular groove, thus achieving the function of limiting the position.
[0011] Preferably, a rectangular plate is fixedly connected to the inner wall of the material feeding frame, and a first screw is threadedly connected to the surface of the rectangular plate. One end of the first screw is rotatably connected to a limiting plate.
[0012] The effect achieved by the above components is that, under the action of the first screw and the limiting plate, the tea leaves will not slide down the surface of the screen quickly, thereby limiting the speed at which the tea leaves fall and thus thoroughly separating the debris.
[0013] Preferably, a sliding rod is slidably connected to the surface of the rectangular plate, and the other end of the sliding rod is fixedly connected to the surface of the limiting plate.
[0014] The effects achieved by the above components are as follows: Under the action of the sliding rod, the speed limiting plate will not rotate with the rotation of the first screw. When it is necessary to sift the tea, the kneading disc is pulled to one side and tilted, so that the tea inside the kneading disc falls into the inside of the feeding frame. The screen is placed inside the rectangular groove. Under the action of the washer, the screen will not directly contact the rectangular groove, thus achieving a rigid contact. Under the action of the round rod and the retaining ring, the screen will not slip out of the inside of the rectangular groove, thus achieving the limiting function. Tightening the first screw by hand causes the limiting plate to move smoothly downward under the action of the sliding rod, thus limiting the tea, and allowing the tea debris to fall through the screen, thus achieving the sieving function.
[0015] Preferably, the fixing device includes clips fixedly connected to the side of the material drop frame, and the clips are evenly arranged on the side of the material drop frame.
[0016] The effect achieved by the above components is that, under the action of the clips, the collection bag can be stuck on the surface of the material drop frame, thereby achieving the function of fixing.
[0017] Preferably, an L-shaped plate is fixedly connected to the side of the material feeding frame, a second screw is threadedly connected to the side of the L-shaped plate, an extrusion plate is rotatably connected to one end of the second screw, a fixing rod is fixedly connected to the side of the extrusion plate, and the fixing rod is slidably connected to the surface of the L-shaped plate.
[0018] The effect achieved by the above components is that, under the action of the second screw and the extrusion plate, the collection bag can be fixed on the surface of the discharge frame, thereby achieving the function of fixing. Under the action of the fixing rod, the extrusion plate will not rotate with the rotation of the second screw.
[0019] Preferably, a rubber strip is fixedly connected to the side of the extrusion plate.
[0020] The effect achieved by the above components is as follows: under the action of the rubber strip, the collection bag will not slip off. When it is necessary to collect tea leaves, place the collection bag on the surface of the dropping frame, put the collection bag on the surface of the clip, and turn the second screw by hand. Under the action of the fixing rod, the extrusion plate will not rotate with the rotation of the second screw, so that the extrusion plate can press against the surface of the dropping frame, thereby achieving the effect of fixing.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] In this invention, by setting up a sieving device, when tea needs to be sieved, the kneading disc is pulled to one side and tilted, causing the tea leaves inside the kneading disc to fall into the material feeding frame. The screen is placed inside the rectangular groove, and the gasket prevents the screen from directly contacting the rectangular groove, thus achieving a rigid contact. The round rod and the retaining ring prevent the screen from slipping out of the rectangular groove, thus achieving a limiting effect. By turning the first screw by hand, the limiting plate moves smoothly downward under the action of the sliding rod, thereby restricting the tea leaves and causing the tea debris to fall through the screen, thus achieving the sieving effect and solving the problem that the debris in the kneaded tea leaves cannot be sieved.

[0027] Example 1, such as Figure 1-3 As shown, a tea processing and kneading device includes a support 1, a motor 5 fixedly connected inside the support 1, a crank connecting rod 8 rotatably connected to the top of the support 1, a kneading drum 6 rotatably connected to one end of the crank connecting rod 8, an adjusting component 7 on the top of the kneading drum 6, the adjusting component 7 including a threaded rod, an adjusting rod threadedly connected to the surface of the threaded rod, a kneading block fixedly connected to one end of the adjusting rod, the kneading block being disposed inside the kneading drum 6, a kneading disc 4 on the top of the support 1, a material discharge frame 9 inside the support 1, and a material discharge frame 9 containing a kneading disc 4. The sieving device 2 and the feeding frame 9 are equipped with a fixing device 3 on their sides. When it is necessary to knead the tea leaves, the withered tea leaves are placed on the surface of the kneading pan 4. The motor 5 is started, so that the crank connecting rod 8 rotates through the coupling at the output end of the motor 5. This causes the kneading barrel 6 driven by the crank connecting rod 8 mechanism to make an eccentric horizontal rotation relative to the kneading pan 4 on the pan surface. This causes the tea leaves in the kneading barrel 6 to continuously turn over with the movement of the kneading barrel 6. Through the pressure device, the tea leaves are pressed and kneaded by the ridges on the kneading pan 4, so that the leaves are rolled into strips and tea juice is squeezed out, thereby achieving the kneading effect.
[0028] Reference Figure 2The screening device 2 includes a rectangular groove 21 inside the material feeding frame 9. A screen 22 is installed inside the rectangular groove 21. Under the action of the screen 22, tea debris is screened off, thus achieving the screening function. When the tea needs to be kneaded, the withered tea leaves are placed on the surface of the kneading disc 4. The motor 5 is started, causing the crank connecting rod 8 to rotate through the coupling at the output end of the motor 5. This causes the kneading drum 6, driven by the crank connecting rod 8 mechanism, to perform an eccentric horizontal rotation relative to the kneading disc 4 on the disc surface. The tea leaves inside the kneading drum 6 continuously tumble with the movement of the kneading drum 6, and the tea leaves are pressurized by the pressurizing device and kneaded by the kneading disc 4. The kneading action of the upper ribs rolls the leaves into strips and squeezes out tea juice, thus achieving the kneading effect. A washer 28, a rubber ring, is fixedly connected to the inner wall of the rectangular groove 21. The washer 28 prevents the screen 22 from directly contacting the rectangular groove 21, achieving rigid contact. A round rod 23 is fixedly connected to the inner wall of the rectangular groove 21, and a retaining ring 24, also a rubber ring, is fixedly connected to the surface of the round rod 23. The action of the round rod 23 and the retaining ring 24 prevents the screen 22 from slipping out of the rectangular groove 21, thus achieving a limiting effect. The inner wall of the material feeding frame 9 is fixedly connected to... A rectangular plate has a first screw 25 threadedly connected to its surface. One end of the first screw 25 is rotatably connected to a limiting plate 27. The action of the first screw 25 and the limiting plate 27 prevents tea leaves from quickly sliding off the surface of the sieve 22, thus limiting the speed at which the tea leaves fall and thoroughly separating out debris. A sliding rod 26 is slidably connected to the surface of the rectangular plate. The other end of the sliding rod 26 is fixedly connected to the surface of the limiting plate 27. Under the action of the sliding rod 26, the speed limiting plate 27 does not rotate with the rotation of the first screw 25. When sieving the tea leaves is required, the kneading disc 4 is pulled to one side and... The tea leaves are tilted, causing them to fall into the feed box 9. The screen 22 is placed inside the rectangular groove 21. With the action of the washer 28, the screen 22 will not directly contact the rectangular groove 21, thus achieving a rigid contact. With the action of the round rod 23 and the retaining ring 24, the screen 22 will not slip out of the rectangular groove 21, thus achieving a limiting effect. By turning the first screw 25 by hand, the limiting plate 27 will move smoothly downward under the action of the sliding rod 26, thus restricting the tea leaves and causing the tea debris to fall through the screen 22, thus achieving the screening effect.
[0029] Reference Figure 3The fixing device 3 includes clips 36 fixedly connected to the side of the material drop frame 9. The clips 36 are evenly arranged on the side of the material drop frame 9. Under the action of the clips 36, the collection bag can be clipped onto the surface of the material drop frame 9, thereby achieving the fixing function. An L-shaped plate 31 is fixedly connected to the side of the material drop frame 9. A second screw 32 is threadedly connected to the side of the L-shaped plate 31. One end of the second screw 32 is rotatably connected to an extrusion plate 34. A fixing rod 33 is fixedly connected to the side of the extrusion plate 34. The fixing rod 33 is slidably connected to the surface of the L-shaped plate 31. Under the action of the second screw 32 and the extrusion plate 34, the collection bag can be fixed to the surface of the material drop frame 9. The pressing plate 34 is fixed to the surface of the material drop frame 9 under the action of the fixing rod 33, so that the pressing plate 34 will not rotate with the rotation of the second screw 32. The side of the pressing plate 34 is fixedly connected with a rubber strip 35. Under the action of the rubber strip 35, the collecting bag will not slip off. When it is necessary to collect tea leaves, place the collecting bag on the surface of the material drop frame 9, put the collecting bag on the surface of the clip 36, and turn the second screw 32 by hand. Under the action of the fixing rod 33, the pressing plate 34 will not rotate with the rotation of the second screw 32, so that the pressing plate 34 can be pressed against the surface of the material drop frame 9, thereby achieving the fixing function.
[0030] Working principle: When the tea processing kneading device is needed, the withered tea leaves are placed on the surface of the kneading disc 4. The motor 5 is started, causing the crank connecting rod 8 to rotate through the coupling at the output end of the motor 5. This causes the kneading barrel 6, driven by the crank connecting rod 8, to rotate eccentrically relative to the kneading disc 4 on the disc surface. The tea leaves inside the kneading barrel 6 continuously tumble with the movement of the kneading barrel 6. Through the pressure device and the kneading action of the ribs on the kneading disc 4, the tea leaves are rolled into strips and tea juice is squeezed out, thus achieving the kneading effect. When the tea leaves need to be sieved, the kneading disc 4 is pulled to one side and tilted, causing the tea leaves inside the kneading disc 4 to fall into the inside of the feed frame 9. The screen 22 is placed inside the rectangular groove 21. Under the action of the washer 28, the screen... Screen 22 will not directly contact rectangular groove 21, thus achieving rigid contact. Under the action of round rod 23 and retaining ring 24, screen 22 will not slip out of rectangular groove 21, thus achieving the limiting function. Tighten the first screw 25 by hand, so that the limiting plate 27 moves smoothly down under the action of sliding rod 26, thereby limiting the tea leaves, so that the tea leaves debris falls through screen 22, thus achieving the screening function. When it is necessary to collect the tea leaves, place the collection bag on the surface of the dropping frame 9, put the collection bag on the surface of the retaining pin 36, and tighten the second screw 32 by hand. Under the action of fixing rod 33, the pressing plate 34 will not rotate with the rotation of the second screw 32, so that the pressing plate 34 can press on the surface of the dropping frame 9, thus achieving the fixing function.
