Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen appliances, and more specifically, particularly relates to a tea cold air rapid air selection device. Background Art

[0002] Killing the green tea is the first step in the initial processing of green tea, yellow tea, black tea, etc. Its purpose is to destroy and passivate the oxidase activity in the fresh leaves through high temperature, make the tea leaves softer, and promote the formation of tea aroma. Wind selection is an essential step in the tea processing process. Its purpose is to remove impurities, sand and gravel in the tea leaves through fans and select pure tea leaves.

[0003] For example, the utility model patent with the announcement number CN216225462U discloses a wind-powered sorting machine for rapid cooling of tea production, including a machine body, a feed hopper, a guide plate, an exhaust hole, an air intake joint, a fan, a refrigerator, a baffle conveyor belt, etc. By arranging a guide plate in the machine body, the tea leaves after withering are placed on the baffle conveyor belt through the feed hopper for preliminary cooling, and the refrigerator cools the tea leaves on the guide plate again through the exhaust hole. The tea leaves after cooling are sorted by the fan. Since the temperature of the tea leaves after withering is relatively high, the temperature will drop rapidly after encountering cold air, and the tea leaves themselves still contain a certain amount of moisture. The temperature drop will cause the water vapor to condense into water droplets quickly, and the water droplets adhere to the tea leaves, so that the tea leaves form tea scale on the surface of the baffle conveyor belt during transportation, resulting in an uneven surface of the baffle conveyor belt. Therefore, a brush is used to clean the conveyor belt in the prior art. However, since the baffle conveyor belt is used for transportation during tea processing and transportation, the baffle conveyor belt is not cleaned cleanly by the brush, resulting in low tea processing efficiency.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a cold air rapid air selection equipment for tea is provided, in order to achieve a more practical purpose. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a cold air rapid air selection device for tea, so as to solve the problem that the baffle conveyor belt is not cleaned thoroughly when the brush is used for conveying tea during processing and transportation, resulting in low tea processing efficiency.

[0006] The purpose and effect of the cold air rapid air selection equipment for tea leaves of the utility model are achieved by the following specific technical means:

[0007] A tea cold air rapid air selection device comprises an air selector and a blower, wherein an inclined mounting frame is arranged on one side of the air selector, a chain transmission mechanism is arranged in the mounting frame, the chain transmission mechanism comprises chains on both sides of the inner side of the mounting frame, the corresponding chain links on the two chains are connected by a connecting rod, a conveyor belt is laid on the connecting rod, sprocket wheels are arranged at both ends of the chain, the corresponding sprocket wheels of the two chains are connected by a connecting shaft, the connecting shaft is passed through the mounting frame, a plurality of blocks are hinged on the two chains, magnets are arranged at the ends of the baffles, and the ends of the symmetrical blocks on the two chains are magnetically connected;

[0008] A connecting plate is provided inside the top of the mounting frame, a blocking block is provided on the connecting plate, the tail of the mounting frame protrudes to form a box body, a rotating roller brush cleaner is provided on the top of the mounting frame below the chain transmission mechanism, three-axis cylinders are installed on both side walls of the tail of the mounting frame, the output shafts of the three-axis cylinders correspond to the baffles, and the chain transmission mechanism and the rotating roller brush cleaner are both driven by motors.

[0009] Furthermore, the chain is provided with a plurality of fixed blocks, which are rotatably connected to the corresponding baffles via a rotating shaft, and a torsion spring is sleeved on the rotating shaft, one end of the torsion spring is clamped on the fixed block, and the other end is clamped on the baffle.

[0010] Furthermore, a residue basket is provided under the rotary roller brush cleaner, and the residue basket is connected to the mounting frame through a partition. The residue basket can collect tea stains that fall from the surface of the conveyor belt when the rotary roller brush cleaner is used to clean the conveyor belt.

[0011] Furthermore, guide plates are provided on both sides of the interior of the box.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] By setting baffles, blocking blocks, rotary roller brush cleaners and three-axis cylinders, the ends of the two baffles are magnetically connected, and the tea leaves are evenly distributed on the surface of the conveyor belt. As the chain transmission mechanism moves, the blocking blocks separate the two magnetically attracted baffles on the return conveyor belt. After the baffles are separated, the rotary roller brush cleaner can clean the tea stains on the surface of the conveyor belt. The two three-axis cylinders simultaneously push the two baffles inward and re-magnetically connect the two baffles, thereby satisfying the requirement that the tea leaves can be evenly distributed when the two baffles are magnetically connected, and the rotary roller brush cleaner can clean the conveyor belt when the two baffles are separated, thereby improving the processing efficiency of the tea leaves.

[0024] Example:

[0025] As attached Figure 1To Attachment Figure 5 As shown:

[0026] The utility model provides a tea cold air fast air selection device, comprising an air selector 1 and a blower 2. The air selector 1 is internally connected to the blower 2. The air selector 1 can use the wind force blown by the blower 2 to make the whole tea fall first, and the broken tea leaves, impurities and sand and gravel in the tea fall in turn, so as to achieve the effect of wind screening of the tea leaves.

[0027] like Figures 4 to 5 As shown, an inclined mounting frame 3 is provided on one side of the winnowing machine 1, and a chain conveying mechanism 4 is provided in the mounting frame 3. The chain conveying mechanism 4 includes chains 41 arranged on both sides of the inner side of the mounting frame 3. The two chains 41 are connected by a connecting rod through corresponding chain links 42. A conveyor belt 44 is laid on the connecting rod. Tea leaves can be poured onto the conveyor belt 44 to prevent the tea leaves from being leaked into the mounting frame 3 due to their small size. Sprocket wheels 45 are provided at both ends of the chains 41. The sprocket wheels 45 corresponding to the two chains 41 are connected by a connecting shaft 46. The connecting shaft 46 is penetrated on the mounting frame 3. A motor is provided at one end of the connecting shaft 46. The motor drives the connecting shaft 46 to drive the sprocket wheel 45 to move. The tea leaves move along with the conveyor belt 44. The arrangement of the strip conveying mechanism 4 can transport tea leaves from a low place to a high place for classification and screening, thus avoiding manual transportation of tea leaves and saving labor costs. A plurality of fixed blocks 47 are arranged on the two chains 41, and the fixed blocks 47 are connected to the baffle 48 through the rotating shaft 43. A torsion spring 49 is sleeved on the rotating shaft 43, and one end of the torsion spring 49 is clamped in the fixed block 47, and the other end is clamped on the baffle 48. The torsion spring 49 can be used to store and release torque energy. A magnet is arranged at the end of the baffle 48, and the end magnetic poles of the two baffles 48 attract each other, so that the ends of the two baffles 48 are magnetically connected to divide the conveyor belt 44 into independent spaces, thereby avoiding uneven distribution of tea leaves and preventing tea leaves from sliding down and causing accumulation during tea leaves transportation.

[0028] like Figure 4 As shown, a connecting plate 5 is arranged inside the top of the mounting frame 3, and the connecting plate 5 can block the tea leaves falling along the output end of the chain conveying mechanism 4 outside the connecting plate 5, and a blocking block 6 is arranged on the connecting plate 5. When the two baffles 48 magnetically attracted together pass through the blocking block 6, the end magnetic poles of the two baffles 48 magnetically attracted together are temporarily not sensed and separated from each other, and the torsion spring 49 drives the baffle 48 to rotate and rebound with the rotating shaft 43 as the axis, so that the two baffles 48 can be quickly separated;

[0029] like Figure 3As shown, a rotary roller brush cleaner 7 is arranged on the top of the mounting frame 3, and the rotary roller brush cleaner 7 is located below the chain transmission mechanism 4. When the motor drives the cylindrical nylon brush, the brush tip slightly contacts the surface of the conveyor belt 44, and the rotation direction of the cylindrical nylon brush is opposite to the running direction of the return conveyor belt 44. After the baffle 48 is separated, the cylindrical nylon brush cleans the tea stains adhering to the surface of the conveyor belt 44. The cylindrical nylon brush is a soft brush to avoid damage to the conveyor belt 44 during rotation. The rotary roller brush cleaner 7 is a prior art and will not be described in detail in the present utility model.

[0030] like Figures 1 to 4 As shown, three-axis cylinders 8 are installed on both side walls of the rear part of the mounting frame 3, and the output shaft of the three-axis cylinder 8 corresponds to the baffle 48. The three-axis cylinder 8 is guided by an output shaft and two guide rods, and the on and off of the air source are controlled to realize the linear movement of the piston in the cylinder. The two three-axis cylinders 8 move synchronously, and the two separated baffles 48 are pushed inward at the same time, so that the magnetic poles at both ends of the two separated baffles 48 quickly sense each other, and the ends of the two baffles 48 are magnetically reconnected, and the conveyor belt 44 is re-isolated into an independent space; the three-axis cylinder 8 is a prior art and will not be described in detail in the present utility model.

[0031] like Figure 3 As shown, a slag basket 10 is arranged under the rotary roller brush cleaner 7, and the slag basket 10 is connected to the mounting frame 3 through a partition 11. The slag basket 10 can collect tea stains on the surface of the conveyor belt 44 cleaned by the rotary roller brush cleaner 7, making it easy to take down the slag basket 10 for unified cleaning.

[0032] like Figure 3 As shown, guide plates 12 are provided on both sides of the box body 9. The guide plates 12 can disperse and guide the tea leaves so that the tea leaves can fall accurately on the conveyor belt 44.

[0033] When using:

[0034] The tea leaves are poured into the box 9, and the tea leaves fall onto the conveyor belt 44 through the guide plate 12 in the box 9. Since a plurality of fixed blocks 47 are arranged on the chain 41, and the fixed blocks 47 are rotatably connected with the baffle plate 48 through the rotating shaft 43, when the tea leaves reach the output end of the chain conveyor mechanism 4, the tea leaves fall into the air separator 1 with the center of gravity, and the blower 2 performs wind screening on the fallen tea leaves. After the two magnetically attracted baffle plates 48 on the return chain conveyor mechanism 4 pass through the blocking block 6, the magnetic poles at both ends of the two baffle plates 48 are temporarily insensitive, and the baffle plates 48 are torsionally spring-loaded with the rotating shaft 43 as the axis. 49 is separated quickly, without the baffle 48 as an obstacle, the brush tip of the cylindrical nylon brush contacts the surface of the conveyor belt 44, and the motor drives the cylindrical nylon brush to rotate quickly to clean the tea stains on the surface of the conveyor belt 44. The two three-axis cylinders 8 push the two separated baffles 48 inward synchronously respectively, and the end poles of the two baffles 48 are quickly induced and magnetically connected, restoring the two baffles 48 to be magnetically attracted together to divide the conveyor belt 44 into independent spaces, and the tea leaves are transported, avoiding uneven distribution of the tea leaves and preventing the tea leaves from sliding down and causing accumulation during the transportation process, thereby improving the processing efficiency of the tea leaves.

[0035] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
