Description

Technical Field

[0001] This utility model relates to the technical field of tea processing equipment, specifically to a quick demolding component for compressed tea forming. Background Technology

[0002] Compressed tea (also known as cake tea or compressed tea cake) is an important commodity form of Pu'er tea, black tea, and some reprocessed teas. Its forming process usually includes weighing, steaming and softening, putting into mold, pressing into cake, demolding, and drying. At present, the mainstream compressed tea forming equipment in the industry usually consists of three parts: pressing mechanism, mold assembly, and demolding mechanism.

[0003] In existing equipment, the lower die and outer ring die are mostly fixedly connected. After the tea cake is pressed under high temperature and humidity, vacuum adsorption and tea juice will form on the surface, resulting in frictional adhesion. When demolding, the mold needs to be pulled or knocked, which can easily cause the edges of the tea cake to break and crumble, and also increase mold wear. Secondly, there is a lack of effective separation structure during demolding, and the adhesion between the tea cake and the surface of the lower die is difficult to remove quickly, usually requiring manual prying with tools. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a rapid demolding assembly for compressed tea molding, comprising a demolding platform, a base below the demolding platform, and a column connecting the demolding platform and the base; a top frame above the demolding platform, an upper cylinder mounted at the bottom of the top frame, with an upper pressure mold fixed to the output end of the upper cylinder; a lower cylinder mounted on the top of the base, with its output end facing upwards and fixed to a lower pressure mold; an extension groove for the lower pressure mold to pass through is provided in the middle of the demolding platform; an annular outer ring module is fixed on the top of the demolding platform, with its middle section connected to the extension groove; a mounting plate is provided on the top of the demolding platform behind the outer ring module, an electric telescopic rod is mounted on the front wall of the mounting plate, a connecting frame is fixed to the telescopic end of the electric telescopic rod, and a demolding blade is mounted on the front wall of the connecting frame.

[0005] Furthermore, the bottom of the upper die is spherical, the top of the lower die is a plane parallel to the demolding blade, and the inner wall of the outer ring module is concave arc-shaped.

[0006] Furthermore, the demolding platform and the top frame are fixed together by an upper positioning rod, and an upper positioning strip is fixed to the outer wall of the upper mold. The upper positioning rod passes through the upper positioning strip and is slidably connected to the upper positioning strip.

[0007] Furthermore, an upper limit bar is fixed to the lower end of the upper positioning rod to prevent the upper die from descending excessively.

[0008] Furthermore, a lower positioning rod is fixed between the demolding table and the base, and a lower positioning strip is fixed to the outer wall of the lower mold. The lower positioning rod passes through the lower positioning strip and is slidably connected to the lower positioning strip.

[0009] Furthermore, a lower limit strip is fixed to the upper end of the lower positioning rod to prevent the lower die from moving too far upward. When the top of the lower positioning strip moves to contact the bottom of the lower limit strip, the top surface of the lower die and the bottom surface of the demolding blade are on the same plane.

[0010] Furthermore, a front baffle is fixed to the front wall of the demolding table directly in front of the demolding blade. The top of the front baffle is higher than the demolding blade to prevent the demolding blade from moving too far forward due to accidental operation.

[0011] The beneficial effects of this utility model are as follows: 1. The outer ring module and the lower pressing mold adopt a separate design. During the demolding stage, the lower pressing mold is driven upward by the lower cylinder, allowing the tea cake to slowly detach from the inner wall of the outer ring module. This avoids the problems of edge damage and crumbs caused by the forced demolding of traditional fixed molds, thus improving the integrity rate of the tea cake. In addition, the demolding blade extends between the tea cake and the lower pressing mold to smoothly cut the adhesion between the two, avoiding deformation of the tea cake caused by manual prying, and further ensuring the shape integrity of the tea cake.

[0012] 2. The cooperation between the upper positioning rod and the upper positioning strip provides vertical guidance for the upper die, preventing die collisions or uneven tea cake pressing caused by upper die misalignment. The cooperation between the lower positioning rod and the lower positioning strip ensures that the lower die remains centered during vertical movement, reducing frictional wear between the lower die and the protruding groove.

[0013] 3. The front baffle is located directly in front of the demolding blade. When the operator over-operates the electric telescopic rod, the front baffle can prevent the demolding blade from moving too far forward, preventing the blade from colliding and being damaged with the outer ring module or other equipment components. At the same time, it can prevent injuries caused by the operator's hand accidentally entering the blade's moving area. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] The present invention will be further described below with reference to the accompanying drawings: A quick demolding component for compressed tea molding, such as Figure 1 and Figure 2 As shown, the device includes a demolding table 1, a base 2 below the demolding table 1, and a column 3 for fixing the demolding table 1 and the base 2 together. A top frame 4 is provided above the demolding table 1, and an upper cylinder 5 is installed at the bottom of the top frame 4. An upper pressure mold 6 is fixed at the output end of the upper cylinder 5, and the bottom of the upper pressure mold 6 is spherical. A lower cylinder 7 is installed at the top of the base 2, and a lower pressure mold 8 is fixed at the output end of the lower cylinder 7 facing upward. An extension groove for the lower pressure mold 8 to pass through is provided in the middle of the demolding table 1. An annular outer ring module 9 is fixed at the top of the demolding table 1. The middle of the outer ring module 9 is connected to the extension groove, and the inner wall of the outer ring module 9 is annular. A mounting plate 10 is provided at the top of the demolding table 1 behind the outer ring module 9. An electric telescopic rod 11 is installed on the front wall of the mounting plate 10. A connecting frame is fixed at the telescopic end of the electric telescopic rod 11. A demolding blade 12 is installed on the front wall of the connecting frame. The top of the lower pressure mold 8 is a plane parallel to the demolding blade 12.

[0019] The upper cylinder 5 on the top frame 4 drives the upper mold 6 to press down, pressing the tea leaves between the outer ring mold 9 and the lower mold 8 into a cake shape; the lower cylinder 7 drives the lower mold 8 to move up and down, both participating in the tea leaf support during molding and driving the tea cake to detach from the outer ring mold 9 during demolding; the outer ring mold 9 forms a ring-shaped forming cavity to ensure the tea cake has a regular shape; the electric telescopic rod 11 cooperates with the demolding blade 12 to cut the adhesion between the tea cake and the lower mold 8, achieving rapid demolding.

[0020] like Figure 1 As shown, in this embodiment, the demolding table 1 and the top frame 4 are fixed together by an upper positioning rod 13. An upper positioning strip 14 is fixed to the outer wall of the upper mold 6. The upper positioning rod 13 passes through the upper positioning strip 14 and is slidably connected to the upper positioning strip 14. An upper limit strip 15 is fixed to the lower end of the upper positioning rod 13 to prevent the upper mold 6 from moving too far downward. A lower positioning rod 16 is fixed between the demolding table 1 and the base 2. A lower positioning strip 17 is fixed to the outer wall of the lower mold 8. The lower positioning rod 16 passes through the lower positioning strip 17 and is slidably connected to the lower positioning strip 17. A lower limit strip 18 is fixed to the upper end of the lower positioning rod 16 to prevent the lower mold 8 from moving too far upward. When the top of the lower positioning strip 17 moves to contact the bottom of the lower limit strip 18, the top surface of the lower mold 8 and the bottom surface of the demolding blade 12 are on the same plane.

[0021] The guiding function of the upper positioning rod 13 and the upper positioning strip 14 controls the movement deviation of the upper mold 6, ensuring no misalignment at the edge; the upper limit strip 15 effectively restricts the downward stroke of the upper mold 6, making the tea cake pressing thickness uniform; the guiding function of the lower positioning rod 16 and the lower positioning strip 17, plus the dual function of the lower limit strip 18, ensures that the demolding blade 12 can be accurately aligned.

[0022] like Figure 1 As shown, in this embodiment, a front baffle 19 is fixed to the front wall of the demolding table 1 directly in front of the demolding blade 12. The top of the front baffle 19 is higher than the demolding blade 12 to prevent the demolding blade 12 from moving too far forward due to misoperation. When the electric telescopic rod 11 malfunctions or is misoperated, causing the blade to move too far forward, the front baffle 19 can block the blade from continuing to move, protecting the operator's personal safety.

[0023] The working principle of this utility model is as follows: First, the lower cylinder 7 is activated, causing the lower pressing mold 8 to move upward along the lower positioning rod 16. Since the lower positioning strip 17 is slidably connected to the lower positioning rod 16, it moves synchronously with the lower pressing mold 8, acting as a guide to prevent the lower pressing mold 8 from shifting during movement. When the lower pressing mold 8 moves into the extension slot and its top is at the bottom of the outer ring module 9, the lower cylinder 7 stops working. At this point, the top of the lower pressing mold 8 and the inner wall of the outer ring module 9 form a closed accommodating space to hold the tea leaves to be pressed.

[0024] The operator pours a measured amount of tea leaves into the opening in the middle of the outer ring module 9. Under gravity, the tea leaves fall into the space between the top of the lower pressing mold 8 and the inner wall of the outer ring module 9, completing the feeding process. The upper cylinder 5 is then activated, causing the upper pressing mold 6 to move downwards along the upper positioning rod 13. The upper positioning strip 14 is slidably connected to the upper positioning rod 13, providing guidance for the downward movement of the upper pressing mold 6. As the upper pressing mold 6 continues to descend, its spherical bottom structure gradually applies pressure to the tea leaves, which are then gradually compressed into a cake shape. When the upper pressing mold 6 reaches its lowest position, the bottom of the upper positioning strip 14 contacts the top of the upper positioning strip 15, and the upper cylinder 5 stops working. At this point, the tea leaves are completely compressed into a tea cake that meets the requirements.

[0025] The upper cylinder 5 is activated and reverses its operation. The upper cylinder 5 drives the upper mold 6 upwards along the upper positioning rod 13, gradually separating it from the tea cake surface until the upper mold 6 returns to its initial position, making room for subsequent demolding. Since the lower mold 8 and the outer ring module 9 are separate, the lower cylinder 7 is activated and moves upwards again. The piston rod of the lower cylinder 7 continues to extend upwards, driving the lower mold 8 and the tightly pressed tea cake upwards. During this process, the tea cake gradually separates from the inner wall of the outer ring module 9, releasing the adhesion between the tea cake and the inner wall of the outer ring module 9. When the top of the lower positioning strip 17 moves to contact the bottom of the lower limit strip 18, the lower cylinder 7 stops working. At this time, the top surface of the lower mold 8 and the bottom surface of the demolding blade 12 are on the same plane, preparing for the demolding blade 12 to extend between the tea cake and the lower mold 8.

[0026] The electric telescopic rod 11 is activated, and its telescopic end extends forward under electric drive, causing the connecting frame and the demolding blade 12 to move forward synchronously. During the movement, the demolding blade 12's blade extends between the tea cake and the lower mold 8. As the electric telescopic rod 11 continues to extend, the demolding blade 12 cuts the adhesion between the tea cake and the lower mold 8, releasing the adhesion between them. Then, the electric telescopic rod 11 reverses its direction, causing the demolding blade 12 to return to its initial position. The lower cylinder 7 also reverses its direction, causing the lower mold 8 to return to its initial position, awaiting the next round of pressing and demolding operations.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
