Description

Technical Field

[0001] The invention relates to the field of tea making, in particular to a cake pressing device for tea making. Background Art

[0002] Tea cakes are tea products made by pressing loose tea into specific shapes (such as round cakes, bricks, and Tuo shapes) through a certain process. The volume of the pressed tea is reduced, making it easier to store and transport. This form is conducive to long-distance transportation and reduces losses caused by transportation. For some teas that need to be stored for a long time, the form of pressed cakes makes it easier to control the amount each time they are taken, reducing the area of ​​tea exposed to the air, thereby maintaining the freshness of the tea.

[0003] The traditional tea cake pressing device for making tea directly presses the prepared tea into shape through a mechanical device. Pressing the tea cake requires a large pressure. The tea leaves are easily crushed when pressing the tea cake under a large pressure. The tea leaves are easily splashed during the pressing process, resulting in waste of tea leaves. It is also not convenient to soften the tea leaves evenly before pressing the tea cakes. The tea leaves usually need to be shaken manually, which is time-consuming and labor-intensive and affects the quality of the tea cakes. Summary of the invention

[0004] In order to overcome the shortcomings of the above-mentioned background technology, the present invention provides a tea cake pressing device for making tea, which is convenient for evenly pressing and softening tea leaves and reducing the crushing of tea leaves during pressing. The tea leaves to be pressed can be shaken before pressing to reduce the interval between tea leaves, so that the tea cakes are pressed more tightly, thereby effectively improving the quality of tea cake pressing.

[0005] A cake pressing device for making tea comprises a support seat, a mounting frame, an electric push rod, a support plate, a cake pressing mechanism and an air jet mechanism. The mounting frame is fixedly connected between two support seats. The two support seats are symmetrically arranged. An electric push rod is installed on each support seat. A support plate is installed on the telescopic rods of the two electric push rods. The cake pressing mechanism is installed on the mounting frame. The cake pressing mechanism is used to press tea leaves into cakes to facilitate the transportation and storage of tea leaves. The air jet mechanism is installed on the support seat. The air jet mechanism is used to soften the tea leaves with water vapor before pressing the tea leaves, reduce tea debris generated by being crushed during pressing, and thus improve the production quality of tea cakes.

[0006] As a further preferred scheme, the protective mechanism includes a pressure plate, a return spring, a protective frame and a support spring. The pressure plate is slidably connected to the support plate, the pressure plate is located above the mounting frame, two return springs are connected between the pressure plate and the support plate, and the two return springs are symmetrically arranged. The mounting frame is slidably connected to the protective frame, two support springs are connected between the protective frame and the mounting frame, and the two support springs are symmetrically arranged.

[0007] As a further preferred embodiment, the jet mechanism includes a screw, a nut, a connecting rod, a slide frame, a support frame, an air pipe, a hose and a sprayer. A screw is installed on the pressure plate, a nut is threadedly connected to the screw, a connecting rod is fixedly connected to the nut, a slide frame is fixedly connected to the mounting frame, a slide frame is provided on the slide frame, a supporting frame is fixedly connected to the connecting rod, the supporting frame is in contact with the slide frame on the slide frame, an air pipe is installed on the support frame, an air inlet and three air outlets are provided on the air pipe, the air inlet of the air pipe is connected to a hose, and a sprayer is installed at the air outlet of each air pipe.

[0008] As a further preferred solution, the chute frame is located outside the protective frame, the sprayer is located above the protective frame, and the sprayer is located below the pressure plate.

[0009] As a further preferred scheme, it also includes a shaking mechanism, which is arranged on a mounting frame, and the shaking mechanism includes a fixed frame, a rack, a push plate, a return spring, a push rod, a limit rod, a ratchet, a cam, a rotating rod, a gear, a swing plate and a return spring. The supporting plate is fixedly connected to the fixed frame, and a rack is installed at the bottom of the fixed frame. The mounting frame is slidably connected with a push plate, and a return spring is connected between the push plate and the mounting frame. The push plate is fixedly connected to the bottom of the push plate, and two limit rods are fixedly connected to the bottom of the mounting frame. The two limit rods are symmetrically arranged, one of the limit rods is rotatably connected with the ratchet, and the ratchet is fixedly connected with a cam, the cam surface is an arc surface and a straight surface, the straight surface of the cam contacts the push rod, the other limit rod is rotatably connected with the rotating rod, the rotating rod contacts the ratchet, the rotating rod is connected with a gear, the gear is meshed with the rack, the rotating rod is rotatably connected with the swing plate, and the swing plate and the rotating rod are connected with a return spring.

[0010] As a further preferred solution, the ratchet is provided with convex teeth and tooth grooves, and the swing plate and the return spring are located in the tooth grooves of the ratchet.

[0011] The beneficial effects are as follows: the pressing plate presses the tea leaves on the mounting plate into a cake shape, so that the pressing plate presses the tea leaves with uniform pressure, which reduces the pressure of the pressing plate when initially pressing the tea leaves, avoids pressing the tea leaves quickly and with high pressure, and effectively reduces the tea leaves from being crushed during the pressing process. The use of the protective frame effectively reduces the splashing of the outer tea leaves during the pressing process, thereby reducing the waste of tea leaves and improving the production quality of the tea cakes.

[0012] The pressing plate drives the screw to move downward, the screw drives the nut to rotate back and forth, and the nut drives the sprayer to rotate accordingly, so that the water vapor softens the tea leaves before the pressing plate presses the tea leaves, reducing tea debris produced by the crushing of the tea leaves during pressing, thereby improving the production quality of tea cakes. The sprayer sprays water vapor evenly on the tea leaves, so that the water vapor softens the tea leaves evenly, and the tea leaves at different positions are evenly softened, which is convenient for the pressing plate to better press the tea leaves into shape.

[0013] Before the pressing plate presses the tea leaves, the push plate pushes the tea leaves up and down. The push plate shakes the tea leaves on the mounting rack, reducing the gaps between the tea leaves, effectively reducing the crushed tea leaves, reducing the air in the tea cakes, making the tea cakes pressed more tightly, and further improving the quality of tea cake pressing.

The supporting spring 54 is compressed, and the pressing plate 51 contacts the tea leaves on the mounting frame 2. The return spring 52 is compressed, and the support plate 4 presses the tea leaves on the mounting frame 2 through the return spring 52 and the pressing plate 51. The pressing plate 51 presses the tea leaves on the mounting plate into a cake shape, so that the pressing plate 51 is evenly The tea leaves are pressed with uniform pressure, which reduces the pressure of the pressing plate 51 when initially pressing the tea leaves, avoids pressing the tea leaves with rapid and high pressure, and effectively reduces the tea leaves from being crushed during the pressing process. The use of the protective frame 53 effectively reduces the splashing of the outer tea leaves during the pressing process, thereby reducing the waste of tea leaves and improving the production quality of the tea cakes.
