Description

Technical Field

[0001] The utility model relates to the technical field of tea processing, in particular to a impurity removing mechanism for a tea fixing machine. Background Art

[0002] Fixing refers to the primary tea processing process of destroying and passivating the activity of oxidase in fresh tea leaves through high temperature, inhibiting the enzymatic oxidation of tea polyphenols and other substances in fresh leaves, and evaporating part of the water in fresh leaves. The purpose is to make the tea leaves soft, facilitate rolling into shape, and at the same time emit the green smell and promote the formation of good aroma. Most of the existing tea fixing machines are drum type, with a stirring shaft equipped with spiral blades inside. However, in the prior art, the humidity of the tea leaves is relatively high at the beginning, and a large amount of water vapor is generated during fixing, which makes the tea leaves easily adhere to the inner wall of the drum and the air inlet holes. The blockage of the air inlet holes will reduce the uniformity of tea fixing. The adhesion of tea residues is not easy to clean, which will seriously affect the color and quality of tea leaves and reduce the fixing efficiency. Content of the Utility Model

[0003] The purpose of the utility model is to provide an impurity removing mechanism for a tea fixing machine, which has the effects of facilitating the removal of impurities adhering to the outer wall of the inner shell of the drum and the air inlet holes, avoiding the blockage of the air inlet holes, facilitating slag collection, and improving the fixing quality and efficiency.

[0004] The above technical purpose of the utility model is achieved through the following technical solutions: An impurity removing mechanism for a tea fixing machine includes a bracket, on which a drum shell is rotatably arranged. Inside the drum shell, a drum inner shell is fixedly arranged through a fixing ring. Air inlet holes are evenly arranged on the drum inner shell. Moving impurity removing rings are respectively arranged on both sides of the fixing ring. A first brush is arranged on the inner wall of the moving impurity removing ring, and a second brush is arranged on the outer wall. The first brush abuts against the outer wall of the drum inner shell, and the second brush abuts against the inner wall of the drum shell. A bidirectional lead screw is rotatably connected inside the fixing ring. The thread directions at both ends of the bidirectional lead screw are opposite, and both ends are threadedly connected with sliders. The sliders are detachably connected with the moving impurity removing rings.

[0005] By adopting the above technical solutions, a bidirectional lead screw with opposite directions at both ends is set. When the bidirectional lead screw is rotated, the sliders move away from or close to each other, thereby driving the two moving impurity removing rings to move together. When the two moving impurity removing rings move away from the fixing ring, the first brush on the inner side brushes off the tea residues adhering to the outer wall of the drum inner shell and blocking the air inlet holes, and the second brush on the outer side brushes off the tea residues adhering to the inner wall of the drum shell. As the moving impurity removing rings move away from each other, the tea residues brushed off and falling onto the inner wall of the drum shell are swept to the outermost side of the drum shell and discharged. Finally, reverse-rotate the bidirectional lead screw to drive the moving impurity removing rings to reset.

[0006] A further setting of the utility model is that sealing covers are arranged at both ends of the drum shell. One end of the sealing cover is hinged to the drum shell, and the other end is connected to the drum shell through bolts.

[0007] By adopting the above technical solution, when discharging is required, the bolt is unscrewed and the sealing cover is opened to discharge the materials, which is convenient for discharging the tea residues swept to the outermost side of the drum shell.

[0008] A further setting of the present utility model is that the movable impurity removal ring is connected to the slider by screws, and the screws pass through the movable impurity removal ring and are threadedly connected to the slider.

[0009] By adopting the above technical solution, when it is necessary to clean or replace the movable impurity removal ring, the bidirectional lead screw is rotated to drive the slider to move to the outermost side of the drum shell, the screws are removed, and then cleaning and replacement can be carried out, which is simple and convenient to use.

[0010] A further setting of the present utility model is that it further includes a heating component, the heating component includes a hot air generator, the drum shell is provided with an air inlet and an exhaust port, and the hot air generator is located at the air inlet.

[0011] By adopting the above technical solution, the hot air generator passes hot air into the space between the drum shell and the inner drum shell through the air inlet, and the hot air uniformly enters the inner drum shell through the air inlet holes for tea leaf fixation, and the waste heat is discharged through the exhaust port.

[0012] A further setting of the present utility model is that the fixed ring is located in the middle of the inner drum shell, and ventilation holes are uniformly arranged on the fixed ring.

[0013] By adopting the above technical solution, the fixed ring is provided with ventilation holes, which can ensure that the hot air uniformly diffuses into the space between the drum shell and the inner drum shell through the ventilation holes, facilitating the circulation of the hot air and ensuring the uniformity of tea leaf fixation.

[0014] A further setting of the present utility model is that it further includes a micro motor, a pulley one is fixedly arranged at the output end of the micro motor, a pulley two is fixedly sleeved in the middle of the bidirectional lead screw, and the pulley one and the pulley two are connected by a belt.

[0015] By adopting the above technical solution, the micro motor drives the pulley one to rotate, and the pulley one drives the pulley two to rotate through the belt, thereby realizing the rotation of the bidirectional lead screw.

[0016] A further setting of the present utility model is that a slag collection frame is arranged at the lower end of the sealing cover for collecting tea residues.

[0017] By adopting the above technical solution, a slag collection frame is arranged to collect the scraped tea residues.

[0018] A further setting of the present utility model is that a handle is arranged on the outer wall of the sealing cover.

[0019] By adopting the above technical solution, the handle is arranged to facilitate the opening of the sealing cover.

[0020] A further setting of the present utility model is that a sealing gasket is arranged on the inner wall of the sealing cover.

[0021] By adopting the above technical solution, a gasket is provided to avoid the loss of hot air and reduce heat loss.

[0022] A further setting of the present utility model is that the outer wall of the drum shell is coated with heat-insulating paint.

[0023] By adopting the above technical solution, the heat-insulating paint prevents scalding.

[0024] The beneficial effect of the present utility model is that by providing a bidirectional lead screw with opposite directions at both ends, when the bidirectional lead screw is rotated, the sliders move away from or close to each other, thereby driving the two moving impurity removal rings to move together. When the two moving impurity removal rings move away from the fixed ring, the inner brush one brushes off the tea residues adhered to the outer wall of the inner shell of the drum and blocked at the air inlet holes, and the outer brush two brushes off the tea residues adhered to the inner wall of the drum shell. As the moving impurity removal rings move away from each other, the tea residues brushed off and dropped onto the inner wall of the drum shell are swept to the outermost side of the drum shell and dropped into the slag collection frame. Finally, reverse-rotate the bidirectional lead screw to drive the moving impurity removal rings to reset. Description of the Drawings
