Description

Technical Field

[0001] This utility model relates to the field of jasmine tea conveying technology, specifically a material conveying device for jasmine tea trans-scenting. Background Technology

[0002] The jasmine tea scenting process is a core step in enhancing the aroma concentration and persistence of jasmine tea. It involves transporting the jasmine tea material during the scenting process after the tea has been scented once or multiple times.

[0003] Currently, traditional conveying equipment only has basic conveying functions. Impurities such as petal fragments and dust remaining in the scenting material cannot be cleaned at the same time. These impurities will affect the tea's aroma absorption efficiency, resulting in uneven aroma after scenting and reducing the quality of the finished product. Therefore, we propose a material conveying device for jasmine tea scenting. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a material conveying device for the scenting of jasmine tea. It solves the problem that existing traditional conveying equipment only has basic conveying functions and cannot simultaneously clean up impurities such as petal fragments and dust remaining in the scenting material. These impurities affect the tea's aroma absorption efficiency, resulting in uneven aroma after scenting and reduced quality of the finished product.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A material conveying device for jasmine tea scenting, comprising a frame, a conveyor belt installed inside the frame, a drive motor installed on one side of the frame, the drive end of the drive motor penetrating the frame and connected to the conveyor belt, a cleaning assembly above the frame, the cleaning assembly comprising two carriers symmetrically mounted on the surface of the frame, three equally spaced guide rods fixedly connected to the side of the two carriers close to each other, and sliding connections on the guide rods. A sliding strip is used, with a dust collection hood installed below it. A baffle is installed on the upper surface of the frame, located between the conveyor belt and the dust collection hood. A servo motor drives the dust collection hood to move back and forth at high frequency along the guide rod. Combined with the negative pressure airflow formed by the external dust collection equipment, the dust collection coverage is expanded, eliminating cleaning dead corners. The mesh of the baffle is precisely matched to the particle size difference between jasmine tea and impurities, allowing only light impurities such as petal fragments and floating dust to pass through. The material is stably blocked. The longitudinal separation area formed by the baffle prevents the material from shifting due to the movement of the dust collection hood, providing sufficient time for impurities to be stirred up, improving the impurity separation rate, and ensuring product quality.

[0006] Furthermore, a connecting pipe is installed on the upper surface of the dust collection hood, and a guide tube is installed at one end of the connecting pipe. The conveyor belt runs at a constant speed to avoid material compression and accumulation, reduce friction damage, and the baffle and net are used to block the material. The dust collection hood only sucks away light impurities to achieve stable dust removal.

[0007] Furthermore, each of the two carriers is fixedly connected to a mounting base on the side away from each other. A servo motor is fixedly connected inside the mounting base. A roller is fixedly connected to the drive end of the servo motor. A pull block is fixedly connected to the upper surface of the dust collection hood. A pull rope is wound on the roller. The end of the pull rope away from the roller is fixedly connected to the surface of the pull block.

[0008] Furthermore, the lower surface of the net is fixedly connected with multiple equally spaced baffles. The dust hood, slider, and other moving parts are driven by guide rods and pull ropes. The structure is simple and not prone to failure. The net adopts a detachable design, making it easy to disassemble and assemble for deep cleaning.

[0009] Furthermore, a base is installed below the frame, and maintenance components are provided on the surface of the frame. The online maintenance function ensures that the dust collection efficiency remains stable and avoids the decline in the impurity removal effect caused by the blockage of the screen. Automated operation reduces individual differences in manual operation, keeps the conveying speed and impurity removal effect of different batches of materials consistent, and improves the standardization level of transfer production.

[0010] Furthermore, the maintenance component includes sliding sleeves installed on both sides of the frame. A striking rod is slidably connected to the inner wall of the sliding sleeve. The striking rod is L-shaped. The striking rod of the maintenance component is precisely matched with the sliding sleeve, and the impact force is controllable, avoiding damage to the barrier and extending the service life of vulnerable parts.

[0011] Furthermore, a positioning seat is fixedly connected to one side of the frame, a telescopic rod is fixedly connected to the inner wall of the positioning seat, a push rod is fixedly connected to the driving end of the telescopic rod, and the lower end of the striking rod is fixedly connected to the upper surface of the push rod.

[0012] In summary, the technical effects and advantages of this utility model are as follows: 1. In this utility model, the servo motor drives the dust collection hood to move back and forth at high frequency along the guide rod. Combined with the negative pressure airflow formed by the external dust collection device, the dust collection coverage is expanded, eliminating cleaning dead corners. The mesh of the baffle is precisely matched to the particle size difference between jasmine tea and impurities, allowing only light impurities such as petal fragments and floating dust to pass through. The material is stably blocked. The longitudinal separation area formed by the baffle prevents the dust collection hood from moving and causing the material to shift, providing sufficient time for impurities to be stirred up, improving the impurity separation rate, and ensuring product quality.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] refer to Figures 1-5The illustrated material conveying device for jasmine tea scenting includes a frame 1, with a conveyor belt 3 installed inside the frame 1. A drive motor 4 is installed on one side of the frame 1, with its drive end passing through the frame 1 and connected to the conveyor belt 3. A cleaning assembly 5 is installed above the frame 1, including two carrier frames 51 symmetrically mounted on the surface of the frame 1. Three equally spaced guide rods 53 are fixedly connected to the side of the two carrier frames 51 that are close to each other. Sliding strips 58 are slidably connected to the guide rods 53, and a dust suction hood 57 is installed below the sliding strips 58. A screen 511 is installed on the upper surface of the frame 1. The screen 511 is located between the conveyor belt 3 and the dust collection hood 57. The servo motor 54 drives the dust collection hood 57 to move back and forth at high frequency along the guide rod 53. Combined with the negative pressure airflow formed by the external dust collection equipment, the dust collection coverage is expanded, and there are no dead corners to clean. The mesh of the screen 511 is precisely matched to the difference in particle size between jasmine tea and impurities, allowing only light impurities such as petal fragments and floating dust to pass through. The material is stably blocked. The longitudinal separation area formed by the baffle 512 prevents the material from shifting due to the movement of the dust collection hood 57, providing sufficient time for impurities to be stirred up, improving the impurity separation rate, and ensuring product quality.

[0019] The upper surface of the dust hood 57 is equipped with a connecting pipe 59, and one end of the connecting pipe 59 is equipped with a guide tube 52. The conveyor belt 3 runs at a constant speed to avoid material compression and accumulation, and reduce friction damage. The baffle 512 and the net 511 are used to block the material. The dust hood 57 only sucks away light impurities to achieve stable dust removal.

[0020] In this case, each of the two carriers 51 is fixedly connected to a mounting base 56 on the side away from each other. A servo motor 54 is fixedly connected inside the mounting base 56. A roller 55 is fixedly connected to the drive end of the servo motor 54. A pull block 510 is fixedly connected to the upper surface of the dust collection cover 57. A pull rope 513 is wound on the roller 55. The end of the pull rope 513 away from the roller 55 is fixedly connected to the surface of the pull block 510.

[0021] The lower surface of the net 511 is fixedly connected with multiple equally spaced baffles 512. The moving parts such as the dust hood 57 and the slide bar 58 are driven by the guide rod 53 and the pull rope 513. The structure is simple and not prone to failure. The net 511 adopts a detachable design, which makes it easy to disassemble and assemble during deep cleaning.

[0022] The frame 1 is equipped with a base 2 underneath and a maintenance component 6 on its surface. The online maintenance function ensures that the dust collection efficiency remains stable and avoids the decrease in the impurity removal effect caused by the blockage of the screen 511. The automated operation reduces individual differences in manual operation, keeps the conveying speed and impurity removal effect of different batches of materials consistent, and improves the standardization level of the transfer production.

[0023] The maintenance component 6 includes sliding sleeves 64 installed on both sides of the frame 1. A striking rod 65 is slidably connected to the inner wall of the sliding sleeve 64. The striking rod 65 is L-shaped. The striking rod 65 of the maintenance component 6 and the sliding sleeve 64 are precisely matched, and the impact force is controllable, so as to avoid damage to the barrier net 511 and extend the service life of vulnerable parts.

[0024] A positioning seat 61 is fixedly connected to one side of the frame 1. A telescopic rod 62 is fixedly connected to the inner wall of the positioning seat 61. A push rod 63 is fixedly connected to the drive end of the telescopic rod 62. The lower end of the striking rod 65 is fixedly connected to the upper surface of the push rod 63.

[0025] The working principle of this utility model is as follows: Connect the end of the conduit 52 away from the connecting pipe 59 to the external vacuuming device to ensure that the vacuuming passage is unobstructed. According to the amount of jasmine tea to be conveyed and the amount of impurities, preset the start and stop frequency and running stroke of the servo motor 54, determine the reciprocating movement range of the vacuum hood 57, check the installation status of the screen 511 and the baffle 512, and ensure that the screen 511 covers the conveyor belt 3 flat. After preparation, start the drive motor 4 on one side of the frame 1. The drive end of the drive motor 4 drives the conveyor belt 3 to rotate at a uniform speed inside the frame 1. Spread the jasmine tea material to be transferred evenly on the input end of the conveyor belt 3. The material moves with the conveyor belt 3 towards the transfer process, and the continuous conveying process is started. The servo motors 54 on the two carriers 51 are activated. The drive ends of the servo motors 54 drive the rollers 55 to rotate at a constant speed. One roller 55 winds up the pull rope 513, while the other roller 55 simultaneously unwinds the pull rope 513. The pull rope 513 drives the dust hood 57 and the slide bar 58 to slide horizontally along the guide rod 53 through the pull block 510. The guiding effect of the guide rod 53 ensures that the movement trajectory of the dust hood 57 is smooth and will not deviate. When the dust hood 57 moves to the limit position of one end of the guide rod 53, the servo motor 54 rotates in the opposite direction, and the rollers 55 switch between winding and unwinding states, driving the dust hood 57 to move to the other side, forming a high-frequency reciprocating motion to expand the dust collection coverage area. When the jasmine tea material passes under the screen 511 along the conveyor belt 3, the light impurities in the material are lifted upwards by the vibration of the conveyor belt 3 and the airflow. The mesh size of the screen 511 is precisely designed to allow only impurities to pass through. The jasmine tea material is stably blocked under the screen 511 and continues to be conveyed. The external dust collection device forms a negative pressure in the dust collection hood 57 through the conduit 52 and the connecting pipe 59. The reciprocating dust collection hood 57 quickly sucks in the light impurities that have passed through the screen 511 and transports them to the external collection device through the pipeline, realizing the efficient separation of material and impurities and ensuring the cleanliness of the material for transfer. Multiple equally spaced baffles 512 on the lower surface of the net 511 extend vertically above the surface of the conveyor belt 3, forming a longitudinally separated area. This prevents the jasmine tea from moving when the dust hood 57 moves. At the same time, after the dust hood 57 moves away from the distance between two baffles 512, the adsorbed jasmine tea falls onto the conveyor belt 3 and adsorbs the jasmine tea in the next area, allowing impurities sufficient time to be lifted and captured by the dust hood 57, thus improving the cleaning effect. After prolonged operation, fine impurities easily adhere to the surface of the screen 511, causing mesh blockage and affecting dust collection efficiency. The maintenance component 6 achieves self-cleaning of the screen 511 through periodic tapping, completing maintenance without stopping the machine. According to the preset cycle, the telescopic rod 62 in the positioning seat 61 on one side of the frame 1 is activated. The drive end of the telescopic rod 62 drives the push rod 63 to move horizontally back and forth. The push rod 63 is fixedly connected to the lower end of the striking rod 65, which in turn drives the L-shaped striking rod 65 to swing up and down along the inner wall of the sliding sleeve 64. During the swinging process, the upper end of the striking rod 65 continuously hits the edge of the screen 511. After being shaken, the impurities attached to the surface of the screen 511 fall off. The fallen impurities are sucked into the dust collection hood 57 with the airflow or fall directly onto the conveyor belt 3 and are transported with the material to the subsequent impurity screening stage. The guiding effect of the sliding sleeve 64 ensures that the movement trajectory of the striking rod 65 is stable, avoiding excessive impact force that could damage the screen 511, realizing online maintenance of the equipment and ensuring the continuity of the conveying and cleaning process.

[0026] After a batch of jasmine tea has been transferred and conveyed, the drive motor 4 is turned off first. After the conveyor belt 3 stops running, the external vacuum cleaner and servo motor 54 are turned off. The vacuum hood 57 stops in the middle position of the guide rod 53 under the tension balance of the pull rope 513. The telescopic rod 62 drives the striking rod 65 to complete the last knocking of the net 511 to clean up the residual impurities. Then the connection between the conduit 52 and the external vacuum cleaner is disconnected, and the equipment returns to its initial state, waiting for the next batch of transfer and conveying operation. The entire workflow, through the coordinated operation of conveying, cleaning, and maintenance components, ensures that jasmine tea is not excessively squeezed or damaged during the trans-scenting process. It also removes impurities through dynamic dust extraction, improving the quality of the tea after trans-scenting. Meanwhile, the convenient online maintenance function reduces equipment operation and maintenance costs, fully meeting the stringent requirements of the jasmine tea trans-scenting process for material conveying.

[0027] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer for control.
