Description

Technical Field

[0001] The present invention relates to the technical field of cypress bark processing technology and equipment, in particular to a preparation technology and equipment for cypress bark extract. Background Art

[0002] Cypress bark is the outer shell of the mature fruit or seeds of plants in the Cupressaceae family (such as Platycladus orientalis and Sabina juniper). It is rich in volatile oils, flavonoids, polysaccharides, terpenes, and minerals. Its uses are diverse, encompassing both traditional health preservation and modern medical technology. Cypress bark extracts, in particular, possess antibacterial and antiviral properties, offering promising applications. Cypress bark extracts are concentrated using modern extraction techniques to extract their active ingredients. Prior to extraction and concentration, the bark undergoes pretreatment, including impurity removal, cleaning, drying, and crushing and screening.

[0003] Crushing and screening are crucial steps in the processing of cypress bark, and their quality and efficiency impact the yield and cost of cypress bark extract. Generally, during crushing and screening, large pieces of bark (such as intact fruit scales and stems) are crushed to a uniform particle size to increase surface area and enhance subsequent extraction efficiency. This process requires multiple screening and collection cycles, and material that does not meet the desired particle size needs to be crushed and rescreened again. During this continuous screening and rescreening process, the continuously falling material must be collected in dedicated collection buckets. During bucket replacement, material leakage and waste are inevitable, and frequent startup and shutdown of the equipment to change buckets reduces production efficiency.

[0004] In order to further improve work efficiency and facilitate the collection of materials that are continuously sieved after the cypress bark is crushed, the present invention proposes a preparation process for the cypress bark extract. Summary of the Invention

[0023] The collecting mechanism 8 comprises a guide cone 801, a guide rod 802, a support plate 803, a roller 804 and a sealing plate 805; the guide cone 801 is fixed to the bottom of the movable frame 3, and the guide cone 801 is used to provide guidance for the screened materials; the guide rod 802 is vertically slidably installed on the inner side of the guide cone 801, and the guide rod 802 is used to drive the support plate 803 and the sealing plate 805 to move synchronously; the support plate 803 is fixed to the bottom end of the guide rod 802, and the support plate 803 is used to receive the thrust from the collecting bucket 5; the roller 804 is rotatably installed at the bottom of the support plate 803 and contacts the top end of the collecting bucket 5, and the roller 804 is used to reduce the friction generated by the relative movement of the support plate (803) and the collecting bucket 5; the sealing plate 805 is fixed to the top end of the guide rod 802, and the sealing plate 805 is used to block the discharge port of the guide cone 801.

[0024] A rotating space for the diverter wheel 701 to rotate is formed inside the discharge box 2, and a movable groove for the movable frame 3 to reciprocate is formed on the inner side of the fixed frame 1.

[0025] In this embodiment, when the cypress shells need to be processed, the crushed cypress shells that need to be screened are placed in the discharge box 2, and the driving motor 6 is started. The operation of the driving motor 6 will synchronously drive the diverter wheel 701 to rotate, and the rotating diverter wheel 701 will evenly discharge the materials in the discharge box 2, so that the materials evenly pass through the diverter wheel 701 and fall on the upper surface of the screen 4, avoiding material blockage; at the same time, the rotation of the diverter wheel 701 synchronously drives the first rotating disk 702 to rotate, so that the outer wall of the first rotating disk 702 rotates eccentrically. One end of the transmission rod 703 connected will also move circumferentially with the rotation of the first rotating disk 702, and then the other end of the transmission rod 703 will also drive the second rotating disk 704 to rotate with the circumferential movement, so that the second rotating disk 7 The gear 705 fixedly connected to the 04 shaft rotates synchronously, and the rotating gear 705 contacts the outer wall of the rack 706 and gives the rack 706 a thrust to move to one side, so that the rack 706 drives the movable frame 3 and the screen 4 to move laterally as a whole, and the protruding portion of the outer wall of the movable frame 3 will move along the outer wall of the positioning rod 707 and give the spring 708 an extrusion force until the outer wall tooth block of the gear 705 no longer contacts the outer wall of the rack 706. Then the movable frame 3 will return to its original position under the action of the spring 708, causing the movable frame 3 and the screen 4 to reciprocate and vibrate, thereby screening the material on the upper surface of the screen 4, reducing the drive unit, and only using one motor to achieve the purpose of uniformly feeding the material and providing screening power, further reducing equipment costs and production costs.

[0026] At this time, the screened material will fall on the inner side of the guide cone 801 and move to the discharge port of the guide cone 801 through the inclined surface on the inner side of the guide cone 801. At this time, the collecting bucket 5 gives the support plate 803 an upward thrust, thereby opening the seal of the sealing plate 805, allowing the material to pass through the discharge port of the guide cone 801 and fall into the interior of the collecting bucket 5. The guide cone 801 will also move with the reciprocating movement of the movable frame 3. The moving guide cone 801 will synchronously drive the roller 804 to reciprocate at the top of the collecting bucket 5, and reduce the friction force on the collecting bucket 5 through the roller 804, so that the collecting bucket 5 will not move until the material inside the collecting bucket 5 is full. When the full collection bucket 5 is removed, the collection bucket 5 will no longer provide support for the support plate 803. Under the action of gravity, the support plate 803, the guide rod 802, and the sealing plate 805 will return to their original positions, and the sealing plate 805 will block the discharge port of the guide cone 801, so that the screen 4 can continue to screen the material, and the screened material will not fall to the ground, reducing the waste of resources and improving work efficiency.

[0027] Please refer to Figures 1-6 An inclined material guide groove is formed on the inner side of the guide cone 801, and the bottom discharge port of the guide cone 801 matches the outer wall of the sealing plate 805.

[0028] In this embodiment: through this structure, under the action of the guide cone 801, the screened materials can be gathered at the discharge port of the guide cone 801 through the inclined guidance. When the collection bucket 5 is removed, the sealing plate 805 will also block the discharge port of the guide cone 801 under the action of gravity.

[0029] Please refer to Figures 1-6 The outer wall tooth blocks of the gear 705 are distributed at a ninety-degree angle on the outer wall of the gear 705, and the outer wall of the gear 705 is meshed with the outer wall of the rack 706. The two ends of the transmission rod 703 are eccentrically connected to the outer walls of the first rotating disk 702 and the second rotating disk 704, and the two ends of the transmission rod 703 are at the same distance from the axial center of the first rotating disk 702 and the second rotating disk 704.

[0030] In this embodiment: through this structure, the rotational force from the diversion wheel 701 can be transmitted to the gear 705 under the action of the transmission rod 703, so that the gear 705 intermittently gives the rack 706 a moving thrust, and the spring 708 gives the movable frame 3 and the screen 4 a spring-like restoring force, so that the movable frame 3 and the screen 4 move back and forth in a spring-like manner, providing power for the vibration screening of the screen 4.

[0031] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
