Abstract
Description
Technical Field
[0001] This utility model relates to the field of tea production, specifically to an automatic feeding machine for tea production. Background Technology
[0002] In large-scale tea production, the feeding process is a crucial step connecting raw material storage with subsequent processing (such as fixation, rolling, and drying). Its automation level and operational stability directly impact tea production efficiency, processing precision, and finished product quality. As the tea industry modernizes and intensifies, traditional feeding methods are no longer sufficient to meet the demands of large-scale production, primarily due to the following problems: Traditional tea feeding relies heavily on manual handling and dumping, which is not only labor-intensive and costly, but also inefficient, typically handling less than 500 kg per hour, failing to match the 1-2 ton processing capacity of modern production lines and becoming a bottleneck for improving production efficiency. Furthermore, manual handling of tea can increase the risk of contamination due to hand hygiene and foreign object contamination, failing to meet food safety standards. To address the shortcomings of manual feeding, some tea companies have begun using ordinary belt conveyors. However, to accommodate the height differences of different processing equipment, inclined conveying is common, but tea leaves easily slide down the belt surface, causing a sharp drop in conveying efficiency. Utility Model Content
[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an automatic feeding machine for tea production to solve the shortcomings of the prior art.
[0004] The purpose of this utility model is achieved through the following technical solution: an automatic feeding machine for tea production, comprising an inclined belt conveyor, side baffles on both sides of the belt conveyor, the side baffles being fixed on the conveyor frame of the belt conveyor, the side baffles contacting the conveying surface of the belt conveyor, a plurality of baffles being fixed on the conveying surface of the belt conveyor, the plurality of baffles being arranged at equal intervals along the conveying direction of the belt conveyor, the input end of the belt conveyor being the bottom end, and a material blocking assembly being provided at the input end of the belt conveyor, the material blocking assembly comprising a fixed plate and a sealing plate, the fixed plate being fixedly connected to the side baffles, the sealing plate being slidably inserted through the bottom of the fixed plate, and the sealing plate having the freedom to move closer to or further away from the belt conveyor.
[0005] Furthermore, the bottom of the fixing plate has an installation cavity, and a spring is installed in the installation cavity. The top of the sealing plate is slidably fitted into the installation cavity. The two ends of the spring are respectively connected to the fixing plate and the sealing plate, and the spring is always in a compressed state.
[0006] Furthermore, a first wedge-shaped surface is provided on the bottom side of the sealing plate away from the output end of the belt conveyor, and the first wedge-shaped surface is located on the moving path of the stop bar.
[0007] Furthermore, a scraping mechanism is provided at the bottom of the output end of the belt conveyor. The scraping mechanism includes a scraper and a mounting frame. The mounting frame is fixed on the conveying frame of the belt conveyor, and the scraper is disposed on the mounting frame. The top of the scraper contacts the conveying surface of the belt conveyor.
[0008] Furthermore, the scraper includes a scraper body and a sliding scraper. The scraper body is fixed on the mounting frame, and the sliding scraper is slidably disposed on the top of the scraper body. The end of the sliding scraper away from the scraper body contacts the conveying surface of the belt conveyor.
[0009] Furthermore, a groove is provided on the top of the scraper body, and a compression spring is provided in the groove. The bottom of the sliding scraper is slidably fitted in the groove. The two ends of the compression spring are respectively connected to the scraper body and the sliding scraper. The compression spring is always in a compressed state.
[0010] Furthermore, a second wedge-shaped surface is provided on the top of the sliding scraper near the output end of the belt conveyor, and the second wedge-shaped surface is located on the moving path of the stop bar.
[0011] The beneficial effects of this utility model are: 1. Several equally spaced baffles fixed on the conveying surface of the belt conveyor can effectively block the tea leaves during inclined conveying (adapting to core scenarios with different height differences in processing equipment), preventing the tea leaves from sliding towards the input end due to gravity. This solves the problem of "material accumulation at the lower end and uneven conveying" in ordinary belt conveyors, ensuring that the tea leaves move forward evenly along the conveying direction and improving the feeding efficiency of tea leaves.
[0012] 2. The spring force can push the sealing plate to continuously adhere to the belt conveyor surface. When the stop bar moves to the input end with the belt, the stop bar will contact the first wedge surface and push the sealing plate to temporarily move upward. After the stop bar passes, the spring will immediately reset so that the sealing plate re-adhere to the belt, thereby ensuring that the sealing plate and the belt conveyor are always in a sealed state, preventing tea leaves from falling from the input end of the belt conveyor.

Detailed Implementation
[0014] Example 1 like Figures 1 to 3 As shown, an automatic feeding machine for tea production includes an inclined belt conveyor 1. Side baffles 2 are provided on both sides of the belt conveyor 1, and the side baffles 2 are fixed to the conveyor frame of the belt conveyor 1, contacting the conveying surface of the belt conveyor 1. Several baffles 3 are fixed to the conveying surface of the belt conveyor 1, and the baffles 3 are arranged at equal intervals along the conveying direction of the belt conveyor 1. The input end of the belt conveyor 1 is the bottom end, and a material blocking assembly is provided at the input end of the belt conveyor 1. The material blocking assembly includes a fixed plate 4 and a sealing plate 5. The fixed plate 4 is fixedly connected to the side baffles 2, and the sealing plate 5 slides through the bottom of the fixed plate 4. The sealing plate 5 has the freedom to move closer to or further away from the belt conveyor 1, thus blocking the sides of the belt conveyor 1 through the side baffles 2. To prevent tea leaves from falling off the side of belt conveyor 1, the tea leaves to be fed are put into the bottom of belt conveyor 1, and the belt conveyor 1 lifts and conveys the tea leaves. The baffle 3 blocks the tea leaves, preventing them from sliding towards the input end due to gravity. This solves the problem of "material accumulation at the bottom and uneven conveying" in ordinary belt conveyors, ensuring that the tea leaves move forward evenly along the conveying direction and improving the feeding efficiency of tea leaves. Due to the setting of the baffle 3, the sealing plate 5 will interfere with the conveying surface of belt conveyor 1 when it comes into contact with the baffle 3. Therefore, the sealing plate 5 is set as a sliding structure, which can avoid the movement of the baffle 3 and keep the sealing plate 5 in contact with belt conveyor 1 at all times, thereby sealing the input end of belt conveyor 1 and preventing tea leaves from falling out of the gap between the sealing plate 5 and belt conveyor 1.
[0015] Example 2 Based on Example 1, such as Figure 1 and Figure 3 As shown, a scraping mechanism is provided at the bottom of the output end of the belt conveyor 1. The scraping mechanism includes a scraper 9 and a mounting frame 10. The mounting frame 10 is fixed on the conveying frame of the belt conveyor 1. The scraper 9 is set on the mounting frame 10. The top of the scraper 9 contacts the conveying surface of the belt conveyor 1. The scraper 9 scrapes off the tea leaves adhering to the belt conveyor 1, avoiding the tea leaves from adhering to the belt conveyor 1 and causing waste.
[0016] Example 3 Based on Example 2, such as Figure 1 and Figure 3As shown, the scraper 9 includes a scraper body 11 and a sliding scraper 12. The scraper body 11 is fixed on the mounting bracket 10. The sliding scraper 12 is slidably disposed on the top of the scraper body 11. The end of the sliding scraper 12 away from the scraper body 11 contacts the conveying surface of the belt conveyor 1. A groove 13 is provided on the top of the scraper body 11. A compression spring 14 is disposed in the groove 13. The bottom of the sliding scraper 12 is slidably fitted into the groove 13. The two ends of the compression spring 14 are respectively connected to the scraper body 11 and the sliding scraper 12. The compression spring 14 is always in a compressed state. The top of the sliding scraper 12 is close to the belt conveyor 1. A second wedge-shaped surface 15 is provided on one side of the output end of the conveyor 1. The second wedge-shaped surface 15 is located on the moving path of the baffle 3. Under the action of the compression spring 14, the top of the sliding scraper 12 contacts the conveying surface of the belt conveyor 1 to scrape off the tea leaves. When the baffle 3 runs to the scraper 9, the baffle 3 first squeezes the second wedge-shaped surface 15. Under the action of the second wedge-shaped surface 15, the sliding scraper 12 squeezes the compression spring 14 and moves downward, so that the baffle 3 can pass smoothly through the sliding scraper 12 and avoid interference. At the same time, the sliding scraper 12 contacts the surface of the baffle 3 and can scrape off the tea leaves adhering to the baffle 3.
[0017] Example 4 Based on Example 3, such as Figure 1 and Figure 2 As shown, the bottom of the fixed plate 4 has an installation cavity 6, and a spring 7 is installed inside the installation cavity 6. The top of the sealing plate 5 is slidably fitted inside the installation cavity 6. The two ends of the spring 7 are connected to the fixed plate 4 and the sealing plate 5 respectively. The spring 7 is always in a compressed state. The bottom of the sealing plate 5 has a first wedge surface 8 on the side away from the output end of the belt conveyor 1. The first wedge surface 8 is located on the moving path of the baffle 3. Under the action of the spring 7, the sealing plate 5 contacts the conveying surface of the belt conveyor 1 and scrapes off the adhering tea leaves. When the baffle 3 runs to the sealing plate 5, the baffle 3 squeezes the first wedge surface 8. Under the action of the first wedge surface 8, the sealing plate 5 squeezes the spring 7 and moves upward, so that the baffle 3 can pass smoothly through the sealing plate 5 and avoid interference. The sealing plate 5 contacts the baffle 3 to form a sealing surface and prevent the tea leaves from falling off.
