Description

Technical Field

[0001] The utility model relates to the technical field of core-pulling machines, and in particular to a medicinal material core-pulling machine. Background Art

[0002] The herbal medicine core extractor is a device that separates the inner core and the herbal skin of herbs, and is used to facilitate the processing of herbal cores or herbal skins.

[0003] The working method of the existing medicinal material core-pulling machine is: a V-shaped cutting groove is set on the core-pulling machine, one end of the medicinal material is partially cut into by pressing down the V-shaped cutting tool, and then the other end of the medicinal material is locked and fixed, and the outer skin of the medicinal material is pulled out by moving the other end.

[0004] While this method facilitates core extraction of medicinal herbs, it still presents the following issues: Because the sheath is partially cut through by pressing down on the herb, coupled with the weight of the herb itself, the shearing force on the top of the herb differs from the shearing force on the bottom. This can result in different shearing depths at the top and bottom, with some parts of the sheath being insufficiently cut or parts of the core being excessively cut. Insufficient cutting depth can result in incomplete core extraction, with parts of the sheath remaining attached to the core. Excessive cutting depth can damage the core and easily break it.

[0027] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] like Figures 2 to 6 As shown, this embodiment proposes a medicinal material core-pulling machine, the structure of which includes a fixed seat 1. The placement rack 2 in this embodiment is fixedly set on the fixed seat 1, the placement hole 21 is set on the placement rack 2, and a plurality of cutting tools 4 are set on the placement rack 2, and each cutting tool 4 is evenly distributed along the central axis of the placement hole 21. The first control structure is set on the placement rack 2, and is used to simultaneously control the central movement of each cutting tool 4 and the placement hole 21. The sliding rack 5 is slidingly set on the fixed seat 1. The locking structure is set on the sliding rack 5, and is used to clamp and fix the medicinal material. The second control structure is set between the fixed seat 1 and the sliding rack 5, and is used to control the movement of the sliding rack 5 relative to the fixed seat 1.

[0029] The first control structure in this embodiment includes a rotating member 3, which is rotatably connected to the placement rack 2. A rotating groove 32 is provided on the rotating member 3, and the outer surface of the rotating member 3 and the rotating groove 32 are both cylindrical structures. A plurality of limiting rails 321 are fixedly provided on the side walls of the rotating groove 32, and the distance from one end of the limiting rail 321 and the center of the rotating groove 32 to the distance between the other end of the limiting rail 321 and the center of the rotating groove 32 gradually decreases, and each cutting tool 4 abuts against the limiting rail 321. The rotating wrench 31 is fixedly provided on the outer surface of the rotating member 3 to facilitate the rotation of the rotating member 3. This design allows that when the rotating member 3 rotates, through the sliding connection between the limiting groove and the sliding portion 42, each cutting tool 4 can simultaneously approach the medicinal material and cut into the medicinal material skin synchronously, so that the medicinal material skin can be quickly and evenly shed.

[0030] In this embodiment, the sliding hole 22 is provided on the side wall of the placement hole 21. The cutting tool 4 is slidingly connected to the sliding hole 22. The spring groove 23 is provided on the side of the sliding hole 22 near the rotation groove 32. The limit spring 421 is sleeved and provided on the cutting tool 4. The limit block 43 is provided at the end of the cutting tool 4 near the rotation groove 32. The limit block 43 is a cylindrical structure. One end of the limit spring 421 is fixedly connected to the limit block 43, and the other end of the limit spring 421 is fixedly connected to the bottom of the spring groove 23. The limit block 43 abuts against the limit rail 321. The limit spring 421 ensures that the cutting tool always abuts the limit rail 321. According to the different distances between the limit rail 321 and the center of the sliding hole 22, the rotating wrench 31 is rotated to achieve the synchronous cutting of the cutting tool 4 toward or away from the medicinal material.

[0031] In this embodiment, the sliding hole 22 has a square cross-section to prevent the cutting blade 4 from rotating. The cutting blade 4 comprises a sliding portion 42 and a cutting portion 41, which are slidably connected to the sliding hole 22. The cutting portion 41 has a triangular cross-section to ensure that the center of the cutting portion 41 is subjected to force, making it less likely to break. This design ensures that the cutting blade 4 can cut into the herb skin along its diameter, making it easier to separate the herb skin from the inner core.

[0032] In this embodiment, the first and second sliding grooves 11, 12 are disposed on the fixed base 1 and are parallel to each other. The cross-sections of the first and second sliding grooves 11, 12 are both convex, ensuring that the sliding frame 5 does not disengage from the first and second sliding grooves 11, 12 during sliding. The bottom of the sliding frame 5 is simultaneously slidably connected to the first and second sliding grooves 11, 12. This dual-sliding groove design ensures stable sliding of the sliding frame 5, making it less susceptible to slippage and more stable.

[0033] The second control structure in this embodiment includes a telescopic member 7, the fixed end of which is fixedly connected to the fixed seat 1, and the telescopic end of which is fixedly connected to the sliding frame 5. The telescopic member 7 used in this embodiment is preferably a hydraulic cylinder or a pneumatic cylinder. Among them, the hydraulic cylinder or the cylinder are both existing technologies and are not described in detail in this embodiment. The herbal medicine skin is separated from the herbal medicine core by controlling the hydraulic cylinder or the cylinder. This design can adjust the telescopic stroke of the telescopic member 7 according to the different lengths of the herbal medicine to control the stroke of the herbal medicine skin separating from the herbal medicine core.

[0034] The locking structure in this embodiment includes a first locking member 61 and a second locking member 62, the first locking groove 611 is set at the end of the first locking member 61 close to the second locking member 62, the second locking groove 621 is set at the end of the second locking member 62 close to the first locking member 61, the first screw rod 81 and the second screw rod 82 are rotatably set on the sliding frame 5, the first screw rod 81 and the second screw rod 82 are parallel to each other, the first thread 811 and the second thread 812 are set at both ends of the first screw rod 81, the first thread 811 and the second thread 812 have opposite rotation directions, the third thread 821 and the fourth thread 822 are set at both ends of the second screw rod 82, the third thread 821 and the fourth thread 822 have opposite rotation directions, the first locking member 61 is threadedly connected to the first thread 811 and the third thread 821 at the same time, the second locking member 62 is threadedly connected to the second thread 812 and the fourth thread 822 at the same time, and the conveyor belt 9 is connected to the first screw rod 81 and the second screw rod 82. Such a design can ensure that the first locking member 61 and the second locking member 62 move together or apart synchronously, thereby reducing the time required for locking and improving the efficiency of locking or releasing.

[0035] The working process of this embodiment is as follows: first, the medicinal material is placed in the placement hole 21, and then the rotating wrench 31 is rotated to drive the rotating part 3 to rotate. Under the action of the sliding rail and the limit spring 421, each cutting tool 4 moves toward the medicinal material and cuts the medicinal material skin into and fixes it at the same time. Then, the synchronous belt is started. Driven by the first screw rod 81 and the second screw rod 82, the first locking member 61 and the second locking member 62 move toward each other and lock the medicinal material through the first locking groove 611 and the second locking groove 621. Then, the telescopic member 7 is started to separate the medicinal material skin from the medicinal material core.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
