Description

Technical Field

[0001] This utility model relates to the field of tea production, specifically a tea forming machine with a re-drying function. Background Technology

[0002] A tea forming machine is a device that repeatedly compresses and disperses tea leaves, used for batch and large-scale kneading operations on tea leaves.

[0003] When using a tea forming machine, the mixing and dispersing steps are relatively long while the pressing time is relatively short. Existing forming machines have only one mixing device corresponding to one pressing mechanism, which makes it difficult to handle a larger amount of tea during processing. Moreover, when the tea is pressed and fed into the mixing drum, the existing conveying structure pushes the pressed cube-shaped tea blocks into the drum from the outside of the drum. This can easily cause the tea to break and fall off during the pushing and friction process, falling onto the outside of the equipment and the ground at the bottom. Utility Model Content

[0004] To address the above problems, this utility model provides a tea forming machine with a re-drying function.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A tea forming machine with a re-drying function includes an extrusion section and a stirring section. Material transfer between the extrusion section and the stirring section is achieved through an outlet section and an inlet section. Both the outlet section and the inlet section include a conveyor belt structure. A base frame is provided on the side of the extrusion section. A slide rail is provided on the base frame, and a sliding seat is slidably mounted on the slide rail. The stirring section is movably mounted on the sliding seat. At least two sliding seats and the stirring section are provided on the base frame, and at least three workstations are provided on the base frame to accommodate the stirring section. The stirring section includes an outer chamber and a roller rotatably mounted inside the outer chamber. The extrusion section includes a machine body.

[0006] Furthermore, the conveyor belt structure includes a side frame, several drive rollers rotatably mounted on the side frame, and a conveyor belt nested on the several drive rollers; the top of the lifting platform is provided with a slide rail, the side frame is slidably mounted on the slide rail, and a transmission mechanism is provided between the side frame and the lifting platform to drive the side frame to move towards the base frame on the lifting platform.

[0007] Furthermore, the width of the conveyor belt structure at the top of the lifting platform is less than two-thirds of the diameter of the roller.

[0008] Furthermore, the hot air duct is fixedly installed on the base frame, and the end of the hot air duct is provided with a downwardly extending lower pipe. A flexible hose is fixedly connected downward to the lower pipe, and a movable pipe is fixedly connected to the bottom end of the flexible hose.

[0009] Furthermore, the lower extension tube and the movable tube are provided with a limiting swing frame, and the two limiting swing frames are oscillatingly connected and the swing axis is perpendicular to the axis of the drum. The two ends of the positioning actuator are respectively connected to the two swing frames to drive the movable tube at the bottom end to swing into the drum.

[0010] Furthermore, a baffle is provided at the end of the movable tube via a hinge, and a counterweight is installed at the other end of the baffle via the hinge. The baffle is used to cover the opening at the end of the movable tube.

[0011] Furthermore, the weight of the counterweight is equal to the weight of the baffle, and the counterweight and the baffle are in a balanced state on both sides of the hinge connection point.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0023] Examples, such as Figures 1-5 As shown: This utility model provides a tea forming machine with a re-drying function. The structure includes an extrusion section 1 and a stirring section 6. The extrusion section 1 and the stirring section 6 are connected by a feeding section 2 and a feeding section 3 for material transfer. Both the feeding section 2 and the feeding section 3 include a conveyor belt 21 structure. The feeding section 2 is located at the front end of the extrusion section 1, and the feeding section 3 is located at the side end of the extrusion section 1.

[0024] The extrusion section 1 includes a machine body 11, an upper pressure plate 12, an inner pressure plate 13, and a tilting frame 14. The machine body 11 has a forming cavity in the middle. The upper pressure plate 12 is oscillatingly mounted on the top of the forming cavity and is driven to oscillate downward by an oscillating actuator 15, thereby flattening the material in the forming cavity. The inner pressure plate 13 is slidably mounted in the forming cavity and is driven to move horizontally in the forming cavity below the upper pressure plate 12 by a horizontal push actuator 16, pushing and pressing the material in the forming cavity to form a cuboid shape. The oscillating actuator 15 and the horizontal push actuator 16 are cylinders, hydraulic cylinders, or electric cylinders. The tilting frame 14 is oscillatingly mounted at the front end of the forming cavity. The tilting frame 14 has an "L" shaped structure and is arranged along the side and bottom of the forming cavity. The tilting frame 14 is driven to rotate by a motor. The tilting frame 14 is used to tilt and move the material in the forming cavity to the feeding section 2 at the front end of the machine body 11.

[0025] The extrusion section 1 has a base frame 4 on its side, a slide rail 8 on the base frame 4 and a sliding seat 5 on the slide rail 8. The stirring section 6 is movably installed on the sliding seat 5. The base frame 4 has at least two sliding seats 5 and the stirring section 6. The base frame 4 has at least three stations for accommodating the stirring section 6. One station is located at the delivery section 2, and the remaining stations are distributed on both sides.

[0026] The mixing unit 6 includes an outer chamber 61 and a drum 62 rotatably mounted inside the outer chamber 61. The drum 62 is driven to rotate by a motor. The inner wall of the drum 62 has raised ribs as mixing blades. The bottom of the drum 62 is higher than the machine body 11. A base frame 63 is fixed to the bottom of the outer chamber 61. A rotating shaft 51 is horizontally fixed at the front end of the sliding seat 5. The base frame 63 is rotatably connected to the rotating shaft 51 of the sliding seat 5. A tilting actuator 52 is provided between the rear end of the sliding seat 5 and the base frame 63. The tilting actuator 52 is a cylinder, hydraulic cylinder or electric cylinder, used to drive the outer chamber 61 to swing forward about the rotating shaft 51 as the axis.

[0027] The feeding section 3 is installed on the side of the machine body 11 and points towards the base frame 4. The discharging section 2 is located at the front end of the machine body 11 and includes a lifting platform 25 installed under the conveyor belt 21 structure. The conveyor belt 21 structure includes a side frame 22, several drive rollers 23 rotatably mounted on the side frame 22, and a conveyor belt 21 nested on the drive rollers 23. The drive rollers 23 are driven to rotate by a motor. The feeding section 3 receives the tea leaves poured off the roller 62 through the conveyor belt 21 and then conveys them into the forming cavity of the machine body 11. The top of the lifting platform 25 is provided with a slide rail 8, and the side frame 22 is slidably mounted on the slide rail 8. A transmission mechanism 24 is provided between the side frame 22 and the lifting platform 25 to drive the side frame 22. The lifting platform 25 moves towards the base frame 4. In this embodiment, the transmission structure adopts a belt drive structure. The motor drives the pulley to rotate, thereby moving the transmission belt. The side frame 22 is connected to the transmission belt and moves with it. After the conveyor belt 21 structure of the delivery part 2 is fed into the drum 62, the conveyor belt 21 structure starts to send the material on the conveyor belt 21 into the drum 62, so as to prevent the debris from falling from the gap between the conveyor belt 21 and the drum 62 when the conveyor belt 21 is conveyed outside the drum 62. In this embodiment, the lifting platform 25 adopts the existing scissor-type electric lifting platform 25, which lifts and lowers by unfolding or folding the cross-hinged scissor arm structure, thereby obtaining the lifting function.

[0028] It should be noted that the width of the conveyor belt 21 structure at the top of the lifting platform 25 is less than two-thirds of the diameter of the roller 62, to prevent the conveyor belt 21 structure from being unable to enter the roller 62.

[0029] At least one set of hot air pipes 7 is provided at both ends of the base frame 4. The hot air pipes 7 are fixedly installed on the base frame 4. The hot air pipes 7 are connected to the external hot air supply equipment. The hot air pipes 7 extend into the stirring part 6 to supply hot air to the drum 62 so that the tea leaves can be re-dried.

[0030] In this embodiment, the end of the hot air duct 7 is provided with a downwardly extending lower pipe 71, and a flexible hose 72 is fixedly connected downward to the lower pipe 71. The flexible hose 72 is a corrugated pipe, and a movable pipe 73 is fixedly connected to the bottom end of the flexible hose 72. A positioning actuator 75 is provided between the lower pipe 71 and the movable pipe 73. The positioning actuator 75 is a cylinder or an electric cylinder, which is used to drive the movable pipe 73 to swing. A limiting swing frame 74 is provided on the lower pipe 71 and the movable pipe 73. The two limiting swing frames 74 are oscillatingly connected and the swing axis is perpendicular to the axis of the roller 62. The two ends of the positioning actuator 75 are respectively connected to the two swing frames to drive the movable pipe 73 at the bottom end to swing into the roller 62.

[0031] Furthermore, a baffle 76 is connected to the end of the movable tube 73 via a hinge. A counterweight 77 is installed on the other end of the baffle 76. The baffle 76 is used to cover the opening at the end of the movable tube 73. The weight of the counterweight 77 is equal to the weight of the baffle 76. The counterweight 77 and the baffle 76 are in a balanced state on both sides of the hinge connection point. That is, after the movable tube 73 is vertical and swings, the counterweight 77 and the baffle 76 are in a horizontal state under the suspension of the hinge connection point.

[0032] In summary, during implementation, the tea leaves are stirred and dispersed within two rollers 62. The user first pushes one roller 62 to the feeding section 3. The tilting actuator 52 tilts the roller 62, causing the tea leaves inside to pour through the opening onto the conveyor belt 21 of the feeding section 3. The conveyor belt 21 moves, carrying the tea leaves into the forming cavity of the machine body 11. Meanwhile, the other roller 62 continues to rotate and stir. The upper pressure plate 12 and the inner pressure plate 13 work together to compress the tea leaves tightly within the forming cavity. Then, the flipping frame 14 moves the cube-shaped tea leaves towards the feeding section 2 at the front end of the machine body 11. The lifting platform 25 of the outlet 2 drives the conveyor belt 21 structure to move upward to the opening position of the drum 62. Then the belt drive structure starts and drives the conveyor belt 21 structure to move into the drum 62. When the conveyor belt 21 structure enters the drum 62, the motor drives the transmission roller 23 to start and send the material on the conveyor belt 21 into the drum 62. Then the conveyor belt 21 structure and the lifting platform 25 return to their positions. The user pushes the mixing unit 6 to the side work position, starts the drum 62 to rotate and disperse the material. Then another mixing unit 6 is moved to the work position of the feeding part 3 to perform the above operation.

[0033] In this embodiment, hot air pipes 7 are provided at both ends of the base frame 4. When not in use, the movable pipe 73 hangs down and the baffle 76 blocks the opening of the movable pipe 73. When in use, the positioning actuator 75 drives the movable pipe 73 to swing into the drum 62, so that the movable pipe 73 points to the inside of the drum 62. Then, hot air is supplied to re-dry the tea leaves that are being dispersed inside the drum 62.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
