Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, and in particular to a tea pressing mold and extrusion molding equipment. Background Technology

[0002] In the tea processing industry, tea extrusion molding is an important process. By pressing tea into specific shapes, it not only facilitates storage, transportation, and sales, but also improves the quality and flavor of tea to a certain extent.

[0003] Traditional tea extrusion molding methods mostly rely on manual operation or simple mechanical devices. Manual operation suffers from low efficiency and inconsistent molding quality, making it difficult to meet the needs of large-scale production. Furthermore, using existing molds to press tea leaves into shape makes it difficult to automatically demold the tea leaves after pressing, which can easily damage the integrity of the pressed tea leaves during the demolding process. Therefore, we propose a tea pressing mold and extrusion molding equipment to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing molds are difficult to automatically demold after pressing tea leaves, which easily damages the integrity of the pressed tea leaves during the demolding process. Therefore, this invention proposes a tea pressing mold and extrusion molding equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An extrusion molding apparatus, comprising:

[0007] The mounting box has a platform fixedly installed on its top, and multiple movable holes are evenly spaced on the platform.

[0008] A support plate is set inside the movable hole. The support plate has a through hole and a threaded ring is fixedly installed at the bottom of the support plate.

[0009] The tripod is fixedly installed inside the mounting box.

[0010] Multiple pushing mechanisms are installed at equal intervals on one side of the mounting box. Each pushing mechanism includes a first electric push rod, the output shaft of which extends into the mounting box and is fixedly mounted with a connecting ring.

[0011] The pressing mechanism is installed on the top of the platform, including a mounting bracket fixedly installed on the top of the platform. Multiple second electric push rods are fixedly installed at equal intervals on the top of the mounting bracket. The output shaft of the second electric push rod extends into the mounting bracket and is threadedly connected to a model pressing head.

[0012] The process involves activating the first electric push rod to move the connecting ring laterally, thus moving the tea leaves below the pressing mechanism; then activating the second electric push rod to move the mold pressing head downwards, pressing the tea leaves into shape.

[0013] In one possible design, an annular groove is formed on the inner wall of the movable hole, and a sliding ring is fixedly sleeved on the support plate. The two sides of the sliding ring extend into the annular groove and slide to connect with the inner wall of the annular groove, so that the tea can be easily supported horizontally when pressing the tea.

[0014] A tea pressing mold, used in the extrusion molding equipment described above, includes:

[0015] The model cylinder passes through the support plate, threaded ring, and connecting ring respectively. The model cylinder is provided with an external thread, and the threaded ring is threadedly connected to the external thread. The model cylinder is in contact with the inner wall of the connecting ring.

[0016] The ejection mechanism penetrates the bottom inner wall of the model cylinder and connects to the bottom inner wall of the model cylinder. The ejection mechanism works in conjunction with the tripod.

[0017] In this process, after the tea leaves are pressed into shape, the pressed tea leaves are pushed upward from the mold cylinder by an ejection mechanism.

[0018] In one possible design, the ejection mechanism includes:

[0019] The top rod penetrates the bottom inner wall of the model cylinder and is slidably connected to the bottom inner wall of the model cylinder;

[0020] The ejector plate is fixedly installed at the top of the ejector rod and contacts the inner wall of the mold cylinder;

[0021] The ball head is fixedly installed at the bottom end of the top rod;

[0022] After pressing is completed, the first electric push rod is activated to move the mold cylinder closer to the tripod. After the ball head contacts the inclined surface of the tripod, it pushes the top rod to move upward, pushing the pressed tea leaves upward out of the mold cylinder.

[0023] In one possible design, a connecting plate located below the mold cylinder is fixedly sleeved on the top rod, and a compression spring is sleeved on the top rod between the mold cylinder and the connecting plate. The top and bottom ends of the compression spring abut against the bottom of the mold cylinder and the top of the connecting plate, respectively. When the mold cylinder moves downward toward the mold pressing head, the compression spring pushes the connecting plate downward, which in turn drives the ejector plate downward through the top rod, facilitating the placement of tea leaves.

[0024] In one possible design, the pushing mechanism achieves lateral movement of the connecting ring by extending and retracting the first electric push rod, thereby driving the mold cylinder to move horizontally to adjust the position of the tea leaves, so that the pressing mechanism can press the tea leaves.

[0025] In one possible design, the pressing mechanism uses the extension and retraction of the second electric push rod to move the mold pressing head up and down, thereby applying pressure to the tea leaves placed in the mold cylinder and pressing the tea leaves into shape inside the mold cylinder.

[0026] In one possible design, the mold cylinder is connected to the threaded ring via an external thread, enabling a detachable connection with the support plate. This facilitates the replacement of mold cylinders of different specifications to meet the pressing needs of tea leaves of different shapes and sizes.

[0027] In this application, the mold cylinder is first threaded through the support plate, threaded ring, and connecting ring. The external thread on the mold cylinder is used to connect it to the threaded ring, ensuring tight contact between the inner wall of the mold cylinder and the connecting ring. Then, the tea leaves to be pressed are placed inside the mold cylinder. The first electric push rod is activated, causing its output shaft to move the connecting ring laterally, which in turn moves the mold cylinder downwards towards the mold pressing head. Because the compression spring is under stress, it pushes the connecting plate downwards, which in turn moves the ejector plate downwards via the push rod. This causes the tea leaves to move downwards within the mold cylinder, creating a wrapping effect. After accurately positioning the mold cylinder directly below the mold pressing head, activate the second electric push rod. Its output shaft drives the mold pressing head downwards, allowing it to enter the mold cylinder and apply pressure to the tea leaves, pressing them into shape within the mold cylinder. Activate the first electric push rod, moving the connecting ring and mold cylinder closer to the tripod. Once the ball head contacts the inclined surface of the tripod, as the mold cylinder continues to move, the inclined surface of the tripod pushes the ball head upwards, which in turn moves the push rod and ejector plate upwards, pushing the pressed tea leaves out of the mold cylinder. At this point, the pressed tea leaves can be easily removed.

[0028] Beneficial effects: In this utility model, the extrusion molding equipment can move the connecting ring laterally by activating the first electric push rod through the pushing mechanism. This allows the tea leaves to be moved below the pressing mechanism during the pressing process, making it easier to press the tea leaves.

[0029] In this utility model, the extrusion molding equipment, through the pressing mechanism, can drive the mold pressing head to move downward by activating the second electric push rod, thereby facilitating the pressing and molding of tea leaves;

[0030] In this utility model, the tea pressing mold, through the ejection mechanism, allows the tea leaves to be placed in the mold cylinder, and the first electric push rod to drive the mold cylinder directly below the mold pressing head via the connecting ring. Then, the second electric push rod is activated to drive the mold pressing head into the mold cylinder to press the tea leaves. After pressing, the first electric push rod is activated to drive the mold cylinder closer to the tripod, so that after the ball head contacts the inclined surface of the tripod, it can push the push rod upward, thereby pushing the pressed tea leaves upward out of the mold cylinder, thus facilitating the removal of the pressed tea leaves.

[0031] This invention enables convenient and continuous automatic pressing and molding of tea leaves, achieving automated production. Furthermore, after pressing and molding, the tea leaves can be automatically demolded, preventing damage to their integrity and thus effectively improving the production quality of pressed tea leaves.
