Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, and in particular to a tea flattening device. Background Technology

[0002] Tea leaves refer to the leaves and buds of the tea plant. Generally, it refers to the leaves of the evergreen shrub tea tree, used for brewing tea, and the beverage made from these leaves. Later, it came to mean all herbal teas made from the flowers, leaves, seeds, and roots of plants, such as chrysanthemum tea; and herbal teas made from various medicinal herbs, also known as "lei ya" in Chinese literature. Some countries also have teas made from the leaves of fruits and herbs, such as fruit tea. During the processing of tea leaves, a flattening device is used to flatten them.

[0003] A tea flattening device for tea processing, with publication number CN219844874U, uses the output end of a motor fixed to the top of a positioning seat to drive a positioning screw to rotate. This causes the two ends of a lifting frame to be threadedly connected to one end of the outer wall of two positioning screws, allowing the lifting frame to drive the top lifting seat to rise and fall stably. This allows the lifting seat to be adjusted and interlocked with the positioning groove, thus controlling the size of the inner wall of the positioning groove. This facilitates the production of tea cakes of different sizes using the tea flattening device, increasing its ease of use and efficiency.

[0004] In their daily work, the inventors discovered that although the above-mentioned tea flattening device for tea processing can flatten tea cakes of different sizes, the depth of its positioning groove is fixed, that is, the distance between the bottom of the inner wall of the positioning groove and the extrusion component is fixed. When it is necessary to change the thickness of the tea cake, it cannot be achieved by adjusting the depth of the positioning groove. Instead, it can only rely on replacing the mold with one of different thicknesses, which is cumbersome and costly. Utility Model Content

A U-shaped rod 208 is fixedly installed on the surface of the support base 1. Two moving plates 209 are slidably connected to the outer wall surface of the U-shaped rod 208. The moving plates 209 and the bearing plate 207 are hinged together by a hinge plate 210. A fixing plate 211 is fixedly installed on the surface of the support base 1. A double-headed electric telescopic rod 212 is fixedly installed on the surface. A protruding plate 213 is fixedly installed on the sides of both moving plates 209. The two output ends of the double-headed electric telescopic rod 212 are fixedly connected to the protruding plate 213. An elastic retaining ring is provided on the inner wall of the sleeve 205. An annular groove is opened on the outer wall of the extension rod 206, and the elastic retaining ring engages with the annular groove of the extension rod 206 to limit the sliding displacement of the extension rod 206 within the sleeve 205. The extrusion hole 204 of the operating seat 203 is clearance-fitted with the bearing plate 207. A sealing ring is provided on the edge of the bearing plate 207, and the sealing ring contacts the inner wall of the extrusion hole 204. An elastic retaining ring is fixed to the inner wall of the sleeve 205 through a groove. The two ends of the elastic retaining ring are connected to the inner wall of the sleeve 205 by screws. An annular groove is opened on the outer wall of the extension rod 206, and the elastic retaining ring engages with the annular groove, with the end of the elastic retaining ring extending into the annular groove.

[0027] Reference Figure 2-4As shown in this embodiment: a material handling device 3 is provided on the outer wall surface of the vertical end of one side of the portal frame 4. The material handling device 3 includes a groove 31 opened on the outer wall surface of the vertical end of one side of the portal frame 4. A displacement plate 32 is slidably connected inside the groove 31. The end of the displacement plate 32 away from the groove 31 is fixedly connected to one of the slide plates 202. A bolt 33 is threadedly connected to the surface of the horizontal end of the displacement plate 32. A plurality of threaded holes 34 matching the bolts 33 are evenly opened on the side of the vertical end of one side of the portal frame 4.

[0028] Working principle: When the device is needed, first adjust the position of the bearing plate 207 inside the extrusion hole 204 according to the required extrusion thickness. The double-headed electric telescopic rod 212 can be started by controlling the PLC controller 5. The start of the electric telescopic rod drives the two protruding plates 213 to move away from or towards each other. The movement of the two protruding plates 213 drives the two moving plates 209 to move away from or towards each other on the surface of the U-shaped rod 208 in the opposite direction. The hinge plate 210 moves, pushing the bearing plate 207 upward or downward. This upward or downward movement of the bearing plate 207 causes the extension rod 206 to move inward or outward from the sleeve 205. Simultaneously, the bearing plate 207 changes its position within the extrusion hole 204. When the bearing plate 207 reaches the appropriate position, tea leaves are placed on its surface. The electric telescopic rod is then turned off, and the cylinder 6 is started using the PLC controller 5. The PLC controller automatically adjusts the height of the bearing plate 207. Calculate the downward stroke of cylinder 6. For example, if the height of the bearing plate 207 is 5cm, the downward stroke of cylinder 6 is set to 3cm to ensure the tea cake thickness is 2cm. Cylinder 6 starts and drives the extrusion plate 7 to move downward. The extrusion plate 7 moves downward to flatten the tea leaves on the bearing plate 207. Since the downward height of the extrusion plate 7 is fixed, the up and down movement of the bearing plate 207 can adjust the thickness. After extrusion, cylinder 6 is used to reset the extrusion plate 7. Then, bolt 33 is loosened and unscrewed from the threaded hole 34. The bolt 33 and the threaded hole 34 separate, allowing the displacement plate 32 to be in the concave position. When the inner limit of groove 31 is lost, displacement plate 32 can be moved. The movement of displacement plate 32 inside groove 31 causes slide plate 202 to move inside vertical groove 201. The movement of slide plate 202 inside vertical groove 201 causes operating seat 203 to move. The movement of operating seat 203 creates a gap between itself and bearing plate 207. When operating seat 203 moves to the appropriate position, bolt 33 is screwed into the corresponding threaded hole 34 again to fix the position of displacement plate 32 inside groove 31. At this time, the extruded tea cake can be easily removed through the gap.
