A microwave conditioning device for tea seeds

Abstract

This invention provides a microwave conditioning device for tea seeds. It solves the problem that existing tea seeds placed on a conveyor belt tend to move to the sides of the conveyor belt due to vibration during movement, eventually falling onto the sides of the conditioning device. The accumulated tea seeds are then prone to combustion after heating in the conditioning device. This invention allows a slider movable on a second guide rod to adjust the position of a second mounting plate. This causes the needle rollers on the second mounting plate to press against both sides of the fourth conveyor belt and compress it towards the center of the second guide rod, causing deformation and upward bending of the fourth conveyor belt. This effectively prevents tea seeds from falling due to vibration during the rotation of the fourth conveyor belt. Furthermore, the movable slider allows for easy adjustment of the needle roller position according to different fourth conveyor belts, making it convenient to use and effectively preventing the tea seeds from catching fire after falling.

Description

Technical Field

[0001] This invention relates to the field of tea seed oil production equipment technology, and in particular to a microwave conditioning device for tea seeds. Background Technology

[0002] Tea seeds are the fruit of the tea plant, a member of the Theaceae family, and are a byproduct of tea production. Like any other plant, tea seeds are actually the most nutritious part of the tea tree. Tea seed oil is a high-end woody health oil produced by pressing tea seeds. Current tea seed oil production requires microwave conditioning of the processed tea seeds. However, existing microwave conditioning equipment often generates vibration during operation. As the tea seeds placed on the conveyor belt move, the vibration causes them to shift to the sides of the conveyor belt and eventually fall into the sides of the conditioning equipment. This accumulation of tea seeds can easily burn when heated in the conditioning equipment. There are areas for improvement in the existing technology. Summary of the Invention

[0003] In view of the above-mentioned existing situation, the present invention provides a microwave conditioning device for tea seeds that can effectively prevent tea seeds on the conveyor belt from falling off the conveyor belt.

[0022] The present invention will be further described below with reference to the embodiments illustrated in the accompanying drawings:

[0023] A microwave conditioning device for tea seeds includes a first conveyor frame 80 and a second conveyor frame 81, and a fourth conveyor belt 82 with both ends movably mounted on the first conveyor frame 80 and the second conveyor frame 81 and capable of circulating between them. A first roller 83 and a second roller 84 are rotatably mounted on the first conveyor frame 80 and the second conveyor frame 81, respectively. The two ends of the fourth conveyor belt 82 are respectively fitted onto the first roller 83 and the second roller 84. A microwave conditioning device 85 is disposed between the first conveyor frame 80 and the second conveyor frame 81. 5. Enclosing the outer perimeter of the fourth conveyor belt 82 located above, the microwave conditioning device 85 has a second support frame 86 fixedly installed at its lower end. A second hopper 87 for placing tea seeds onto the fourth conveyor belt 82 is fixedly installed on the first conveyor frame 80. The second hopper 87 is fixedly installed on the first conveyor frame 80 by a fixing frame 108. A second discharge port 109 extending along the width direction of the fourth conveyor belt 82 is provided at the lower end of the second hopper 87. The width of the second discharge port 109 is smaller than the width of the fourth conveyor belt 82. A reinforcing rod 110 is fixedly installed on each side of the second discharge port 109 on the fixing frame 108. The narrower width of the second discharge port 109 effectively prevents tea seeds from falling onto the sides of the upper end of the fourth conveyor belt 82. The upper end of the fourth conveyor belt 82 is a conveying surface 88 for conveying tea seeds from the first conveyor frame 80 to the second conveyor frame 81. Multiple second guide rods 89 extending along the width of the microwave conditioning device 85 and located below the conveying surface 88 are fixedly installed inside the microwave conditioning device 85. Both ends of the second guide rods 89 are fixedly installed on the inner wall of the microwave conditioning device 85. A slider 90, movable along the length of the second guide rod 89, is movably installed at each end of the second guide rod 89. Two second mounting plates 91 are fixedly installed on the upper end of the slider 90. A needle roller 92 rotatably mounted on the second mounting plate 91 faces the conveying surface 88. The needle roller 92 is inclined downwards towards the conveying surface 88, with its upper end above the conveying surface 88 and its lower end below it. A locking nut 93 is movably installed on the slider 90 via a threaded connection to lock the slider 90 onto the second guide rods 89.The position of the second mounting plate 91 is adjusted by the slider 90 movable on the second guide rod 89, so that the needle rollers 92 on the second mounting plate 91 abut against both sides of the fourth conveyor belt 82 and press the fourth conveyor belt 82 towards the center of the second guide rod 89, causing the sides of the fourth conveyor belt 82 to deform and bend upward, effectively preventing tea seeds from falling due to vibration during the rotation of the fourth conveyor belt 82. In addition, the position of the needle rollers 92 can be easily adjusted according to different fourth conveyor belts 82 by the movable slider 90, which is convenient to use and effectively prevents tea seeds from catching fire after falling.

[0024] The slider 90 is movably provided with a rotating plate 111, and the second mounting plate 91 is fixedly mounted on the rotating plate 111. A certain gap is left between the rotating plate 111 and the slider 90. A downwardly extending fixing plate 112 is fixedly mounted on each side of the rotating plate 111. The slider 90 has a through groove 113, which is an oblong hole. The groove 113 slopes from top to bottom away from the locking nut 93. A rotating shaft 114 is fixedly mounted between the two fixing plates 112 and is inserted into the groove 113. The end of the rotating plate 111 facing the locking nut 93 is the rear end. Several tension springs 115 are fixedly installed below the rear end of the rotating plate 111 to drive the rear end of the rotating plate 111 to rotate downward. The front end of the slider 90 is provided with an inclined surface 116. The inclination angle of the inclined surface 116 is the same as the inclination angle of the slide groove 113. Two downward extending push rods 117 are fixedly installed on the lower end face of the front end of the rotating plate 111 and abut against the inclined surface 116. The lower end of the push rod 117 abuts against the inclined surface 116. The lower end of the inclined surface 116 is provided with a downward extending arc-shaped groove 118. When the fourth conveyor belt 82 is circulating and conveying materials, when the weight is large, the fourth conveyor belt 82 presses against the slider 90, causing the rotating shaft 114 on the rotating plate 111 to move downward along the slide 113. The push rod 117 at the front end of the rotating plate 111 moves downward synchronously with the rotating shaft 114 along the inclined surface 116. The rotating shaft 114 moves to the bottom of the slide 113, and the push rod 117 moves to the bottom of the inclined surface 116. As the rotating plate 111 moves downward, it moves towards the middle of the fourth conveyor belt 82, further causing the side of the fourth conveyor belt 82 to curl. At this time, the tension spring is in a compressed state 115. When the weight on the fourth conveyor belt 82 increases further, the lower end of the push rod 117 moves from the inclined surface 116 into the arc groove 118 and rotates downward around the rotating shaft 114. The rotating plate 111 tilts further and causes the side of the fourth conveyor belt 82 to bend upward. At this time, the tension spring 115 is in a stretched state. The tension spring 115 balances the force on both ends of the rotating plate 111, preventing the rotating plate 111 from shaking. This allows the needle roller 92 to adaptively adjust the bending degree of the side of the fourth conveyor belt 82 according to the weight on the fourth conveyor belt 82, thus avoiding adaptive adjustment of materials of different weights during conveying.

[0025] Two third cover plates 100 extending along the length of the microwave conditioning device 85 are fixedly installed on both sides of the microwave conditioning device 85. These third cover plates 100 are located above the sides of the conveying surface 88, with a certain gap between them and the conveying surface 88. The third cover plates 100 are fixed to the inner wall of the microwave conditioning device 85 by multiple connecting rods. By covering the sides of the upper end of the fourth conveyor belt 82 with the third cover plates 100, the sides of the fourth conveyor belt 82 are effectively protected. This prevents the heating rays from directly irradiating the sides of the fourth conveyor belt 82 when there are no damp tea seeds on the sides during the conditioning heating process of the microwave conditioning device 85. This avoids the situation where the sides of the fourth conveyor belt 82 are too hot to heat properly and could scorch them, thus preventing the frequent replacement of the fourth conveyor belt 82.

[0026] The microwave conditioning device 85 has multiple rotating rods 94 fixedly installed inside. These rotating rods 94 are located below the conveying surface 88. A first sleeve 95 extending along the length of each rotating rod 94 is fitted onto the rotating rod 94, and the first sleeve 95 abuts against the lower end of the conveying surface 88. Multiple second sleeves 96 are rotatably mounted on the second support frame 86. These second sleeves 96 are located within the fourth conveyor belt 82, and the distance between the second sleeve 96 and the conveying surface 88 is greater than the diameters of the first roller 83 and the second roller 84. The fourth conveyor belt 82 surrounds the first sleeve 95, second sleeves 96, first roller 83, and second roller 84. The first sleeve 95 supports the upper fourth conveyor belt 82, while the second sleeves 96 stretch the lower fourth conveyor belt 82, ensuring that the fourth conveyor belt 82 remains in a relatively taut state.

[0027] An inclined discharge plate 97 is fixedly installed at one end of the second conveyor frame 81 away from the microwave conditioning device 85. The end of the discharge plate 97 facing the second conveyor frame 81 is located below the second roller 84. A fourth baffle 98, inclined towards the center of the discharge plate 97, is fixedly installed on each side of the discharge plate 97. A second retaining edge 99 is fixedly installed around the outer perimeter of the discharge plate 97 at the end of the second conveyor frame 81 away from the microwave conditioning device 85. Tea seeds on the fourth conveyor belt 82, after passing through the second roller 84, detach from the fourth conveyor belt 82 and fall onto the discharge plate 97, sliding down it. The second retaining edge 99 around the outer perimeter of the discharge plate 97 prevents the tea seeds from falling off the discharge plate 97 and onto the outside.

[0028] The microwave conditioning device 85 has multiple third openings 101 on both sides, connecting to the inside of the microwave conditioning device 85. A door 102 is rotatably mounted at each third opening 101, capable of engaging with the third opening 101. A sealing strip 103 is fixedly mounted on one end of the door 102 facing the microwave conditioning device 85 for engaging within the third opening 101. A locking seat 104 is fixedly mounted on one side of the third opening 101. A notch 105 is opened on the side of the locking seat 104 facing the door 102. A handle 106 is rotatably mounted on the door 102. A limiting block 107 is fixedly mounted on the handle 106, capable of engaging within the notch 105 after the handle 106 is rotated. When the third door 102 is closed, the sealing strip 103 on the third door 102 engages with the third opening 101 to seal the third opening 101. This is more convenient than locking the door 102 by turning the handle 106 so that the limiting block 107 on the handle 106 engages with the notch 105 on the locking seat 104.
