Description

Technical Field

[0001] This utility model relates to tea fixing equipment, and more particularly to a fixing device that facilitates feeding. Background Technology

[0002] A fixation machine is a mechanical device used in tea processing. Its main purpose is to destroy and deactivate the oxidase activity in fresh leaves through high temperatures, inhibiting the enzymatic oxidation of tea polyphenols and other substances in the leaves, and preventing discoloration during the drying process. At the same time, the fixation machine can also remove the grassy odor and promote the formation of a pleasant aroma.

[0003] Chinese patent CN219352958U discloses a buckwheat tea fixing device for easy feeding, including a drum fixing machine and a support platform at the bottom of the drum fixing machine. A collection box is located below the drum fixing machine. A conveying component is located on the side of the drum fixing machine away from the collection box, and a feeding component is located on the side of the conveying component away from the drum fixing machine. The feeding component includes a support plate and a fixed platform on top of the support plate. A motor is mounted on the fixed platform, and the output end of the motor is connected to a rotating rod. Spiral blades are provided on the side wall of the rotating rod, and a feeding pipe is sleeved on the outside of the spiral blades. One end of the feeding pipe is located above the conveying component, and the other end of the feeding pipe is close to the motor. With the conveying component and the feeding component, manual feeding is possible, resulting in high efficiency.

[0004] However, the feeding system of this equipment requires a feeding pipe and a conveyor belt, making the overall structure large and occupying a significant amount of space. Furthermore, the conveyor belt can only transport material to the opening of the fixing drum, where the temperature is relatively low, affecting the fixing quality. This is because tea leaves need to quickly deactivate oxidase activity to prevent reddening. The tea leaves should be evenly pushed into the drum to 1 / 3 to 1 / 2 of its depth to ensure proper initial heating. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a blanching device that facilitates material feeding, solving the problem that existing technologies cannot properly position materials within the blanching drum, thus affecting blanching quality.

[0006] According to an embodiment of this utility model, a blanching device for easy feeding includes a blanching drum, a support frame, a material trough, a first motor, a slider, two slide rails, a pushing component, and a lifting component. The support frame is fixedly installed on one side of the blanching drum. The two slide rails are horizontally arranged and parallel to each other, and the slide rails are slidably connected to the support frame in the vertical direction. The two ends of the slider are slidably connected to the two slide rails respectively. The centerline of the material trough is horizontal and parallel to the slide rails, and the material trough is located in the middle of the two slide rails. The maximum outer diameter of the material trough is smaller than the inner hole of the blanching drum. The first motor is fixedly installed in the middle of the slider, and the output shaft of the first motor is fixedly connected to the center of one end of the material trough. An arc-shaped groove is fixedly provided at the bottom of the slide rail, and the groove is adapted to the material trough. The lifting component is used to make the two slide rails move synchronously in the vertical direction. The pushing component is used to drive the slider to move along the slide rails.

[0007] The technical principle of this utility model is as follows: by moving the material trough, the material trough can enter the inside of the blanching drum, and then rotating the material trough will pour the material into the appropriate position.

[0011] Preferably, the chute is provided with a plurality of rollers that roll in contact with the material trough.

[0012] Preferably, the end of the feed trough away from the blanching drum has an inclined surface inside.

[0013] Preferably, the openings of the two sliding grooves are arranged opposite to each other.

[0014] Compared to existing technologies, this invention offers the following advantages: The lifting component allows the slide rail to move vertically, and the pushing component drives the slider to move along the slide rail, enabling flexible adjustment of the material trough position and precise feeding of tea leaves into the fixing drum. This reduces manual labor intensity and improves feeding efficiency.

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1 , 2As shown in the figure, this utility model embodiment proposes a blanching device for easy feeding, including a blanching roller 1. One end of the blanching roller 1 is for feeding, and the other end is for discharging. The blanching roller 1 maintains a certain distance from the ground to facilitate the installation of a drive device to drive the blanching roller 1 to rotate continuously. This blanching device also includes a support frame 9, a material trough 2, a first motor 7, a slider 14, two slide rails 3, a pushing assembly, and a lifting assembly. The support frame 9 is fixedly installed on one side of the blanching roller 1. The two slide rails 3 are horizontally arranged and parallel to each other. The slide rails 3 are slidably connected to the support frame 9 in the vertical direction. The support frame 9 has four vertical slots. Sliding connecting blocks adapted to the vertical slots are fixedly installed on the slide rails 3. The sliding connecting blocks are vertically arranged elongated structures with an opening on one side of the vertical slot. The sliding connecting blocks are fixedly connected to the slide rails 3 from the opening, and the width of the opening is smaller than the width of the vertical slot. The two ends of the slider 14 are slidably connected to the two slide rails 3 respectively, and the slider 14 remains horizontal. The centerline of the chute 4 is horizontal and parallel to the slide rail 3. The material trough 2 is located between the two slide rails 3. The maximum outer diameter of the material trough 2 is smaller than the inner hole of the blanching roller 1. The centerline of the material trough 2 and the centerline of the blanching roller 1 coincide in the horizontal projection. The first motor 7 is fixedly installed in the middle of the slider 14, and the output shaft of the first motor 7 is fixedly connected to the center of one end of the material trough 2. In this embodiment, a connecting plate 16 is fixedly installed at one end of the material trough 2. The connecting plate 16 is fixedly connected to the output shaft of the first motor 7 to ensure the stability of the connection between the first motor 7 and the material trough 2. An arc-shaped chute 4 is fixedly installed at the bottom of the slide rail 3. The chute 4 is adapted to the material trough 2, and the chute 4 supports the bottom of the material trough 2 to prevent the output shaft of the first motor 7 from bending. The lifting component is used to make the two slide rails 3 move synchronously in the vertical direction. The pushing component is used to drive the slider 14 to move along the slide rail 3. When the slide rail 3 is at its lowest position, the staff can directly put the tea leaves into the feed trough 2. After the slide rail 3 moves upward, the feed trough 2 is aligned with the feed inlet of the blanching drum 1. The push assembly moves the feed trough 2 into the blanching drum 1. Then, the first motor 7 works, causing the opening of the feed trough 2 to rotate to a downward position, so that the tea leaves can fall accurately into the blanching drum 1 at 1 / 3 to 1 / 2 of its depth.

[0022] like Figure 3As shown, preferably, the pushing assembly includes two lead screws 10 and two second motors 8. The slide rail 3 has a sliding groove 17 closed at both ends. The lead screws 10 are disposed within the sliding grooves 17, with both ends of the lead screws 10 rotatably connected to both ends of the sliding grooves 17. The end of the slider 14 is adapted to the sliding groove 17. The second motors 8 are fixedly disposed at the end of the slide rail 3, and the output shaft of the second motor 8 is fixedly connected to the end of the lead screws 10. The slider 14 is threadedly connected to the lead screws 10. The controller is electrically connected to the two second motors 8. In this embodiment, the two second motors 8 rotate synchronously. When the second motors 8 drive the lead screws 10 to rotate, the slider 14 moves.

[0023] like Figure 2 , 3 As shown, preferably, the lifting assembly includes a controller, four guide wheels 11, two sets of traction ropes 6, a main shaft 12, a third motor 13, and two take-up reels 5. The guide wheels 11 are located above both ends of the slide rail 3 and are rotatably connected to the support frame 9. The main shaft 12 is horizontally mounted on the top of the support frame 9 on the side away from the blanching roller 1. The main shaft 12 is perpendicular to the slide rail 3 and is rotatably connected to the support frame 9. The two take-up reels 5 are fixedly mounted at both ends of the main shaft 12. One end of the traction rope 6 is fixedly connected to the take-up reel 5, and the other end of the traction rope 6 passes around the guide wheels 11 in sequence, extends downwards, and is fixedly connected to both ends of the slide rail 3. The third motor 13 is used to drive the main shaft 12 to rotate. The controller and the third motor 13 are electrically connected. After the worker puts the tea leaves into the feed trough 2... The third motor 13 drives the main shaft 12 to rotate. The main shaft 12 drives the take-up reel 5 to wind up the traction rope 6. The traction rope 6 then pulls the slide rail 3 to move in the vertical direction so that the material trough 2 connected to the slide rail 3 is aligned with the blanching roller 1.

[0024] Preferably, the material trough 2 is an arc shell structure with an arc greater than or equal to 90°, and the radius of the material trough 2 is equal to or less than the radius of the fixing drum 1, so as to ensure that the material trough 2 can hold enough tea leaves and can enter the interior of the fixing drum 1.

[0025] like Figure 4 As shown, preferably, the chute 4 is provided with several rollers that roll in contact with the material trough 2. The material trough 2 remains between the two slide rails 3 for an extended period, and the chute 4 provides support. The rollers reduce the friction of the material trough 2 during lateral movement.

[0026] Preferably, the end of the feed trough 2 away from the fixing drum 1 has an inclined surface 15 inside. When the worker puts the tea leaves into the feed trough 2, the tea leaves will gather towards the middle of the feed trough 2. When the feed trough 2 slides into the fixing drum 1, one end of the feed trough 2 always remains in contact with the slide 4, so that the feed trough 2 is always supported, improving the stability and service life of the fixing device.

[0027] Preferably, the openings of the two sliding grooves 17 are arranged opposite to each other, and after the two ends of the slider 14 extend into the sliding groove 4, the sliding groove 17 plays a supporting role for the slider 14.
