Description

Technical Field

[0001] The invention relates to the technical field of traditional Chinese medicine pharmaceutical equipment, and in particular to a device for uniformly obliquely cutting polygonatum while fresh with screening and anti-sticking knife functions. Background Art

[0002] Polygonatum sibiricum is the rhizome of the plant of the genus Polygonatum in the Liliaceae family. It has the effects of nourishing the spleen and moistening the lungs, nourishing yin and promoting body fluid, and strengthening the tendons and bones. It is a traditional tonic in my country. With the improvement of people's health awareness, the market demand for Polygonatum sibiricum has increased significantly, and people's requirements for the stability and uniformity of Polygonatum sibiricum's medicinal effects have also been continuously strengthened.

[0003] In the traditional processing technology of Polygonatum sibiricum slices, manufacturers will dry them before cutting to facilitate slicing, so as to prevent the knife from sticking and ensure the slicing efficiency of the slices. However, this operation will increase the processing steps, and cutting after drying will cause serious loss of Polygonatum sibiricum ingredients and low nutritional value. The added steps will increase costs.

[0004] Fresh processing is a technology for preparing Chinese medicinal materials. It has great potential in ensuring the quality of medicinal materials, reducing production costs and improving production efficiency. It mainly involves cutting the harvested fresh Chinese medicinal materials into slices, blocks, sections, etc.

[0005] At present, most of the fresh cutting of Polygonatum sibiricum is done by workers who wash the Polygonatum sibiricum, remove the beard, scald it in boiling water, and then cut it by a slicer. Due to the irregular shape of Polygonatum sibiricum, the existing slicer will cause the slices to warp and the slices to be poor in shape when cutting Polygonatum sibiricum. Summary of the invention

[0012] A second conveyor belt is arranged on the main frame and is located below the at least two partitions, and the second conveyor belt can drive the target polygonatum located in the single channel to move from the entry end to the exit end;

[0013] The slicing mechanism is installed on the main frame near the exit, and a three-dimensional coordinate system is established with the plane where the second conveyor belt is located as a horizontal reference plane, wherein the X-axis is the travel direction of the second conveyor belt, and the cutter of the slicing mechanism is perpendicular to the horizontal reference plane and the cutter is set at an angle to the X-axis, so as to slice the target polygonatum obliquely.

[0014] According to the device for uniformly beveling fresh Polygonatum with screening and anti-sticking knife functions of the embodiment of the present invention, irregular Polygonatum is pre-screened by a screening mechanism, and target Polygonatum that meets the preset cross-sectional size is screened and enters a single channel, and is transferred to a slicing mechanism for beveling under the action of a second conveyor belt, thereby reducing the warping of Polygonatum while retaining more ingredients. When slicing, the target Polygonatum can be limited from warping up by a limit piece set at the outlet of the single channel, so that the thickness of the slices is uniform, thereby ensuring that the Polygonatum slices have a good slice shape and stable medicinal efficacy.

[0020] A tool holder, the tool holder is fixedly connected to the driving assembly;

[0021] The cutter is detachably mounted on the knife clamp. The adjustment assembly and the gear adjustment slot are used to ensure that the cutter is perpendicular to the horizontal reference plane and that the cutter is set at an angle to the X-axis, thereby being able to cut out Huangjing slices that meet different bevel angles.

[0022] In a possible implementation of the first aspect, a plurality of elastic clips are respectively provided on opposite groove walls in each gear adjustment groove, a first notch is provided between adjacent elastic clips on the same groove wall, and a gap is provided between two opposite elastic clips on different groove walls.

[0023] In a possible implementation manner of the first aspect, the slicing mechanism further includes a peeling mechanism, and the peeling mechanism includes:

[0024] Deck, the deck is fixedly installed between two rails;

[0025] The first scraper and the second scraper are respectively arranged on both sides of the cutter. The first scraper and the second scraper are respectively fixedly installed at the edges of the deck. The scraping mouths of the scrapers are facing and close to the cutter, so as to effectively scrape away the Polygonatum odoratum slices standing on the surface of the cutter when the slice is retracted, thereby improving the slicing efficiency and avoiding the occurrence of knife sticking.

[0026] In a possible implementation of the first aspect, every two partitions are arranged side by side to form a single channel;

[0027] Each of the partitions includes a first connecting piece, a second connecting piece and a third connecting piece formed in one piece.

[0031] The extension kit is nested on the limit plate, and the distance between the extension kit and the cutter can be adjusted by sliding along the limit plate to avoid the situation where the cutter is too far away from the limit plate due to angle adjustment and cannot limit the tilting of the Polygonatum.

[0032] In a possible implementation of the first aspect, the screening mechanism includes:

[0033] A first driving device, the first driving device is fixedly mounted on a main frame located on one side of the second conveyor belt;

[0039] When the screening mechanism is operating, the Polygonatum odoratum falls between the roller brushes under the side cover. The target Polygonatum odoratum that meets the preset requirements will be brushed down to the single channel below by the roller brush rotating in the opposite direction, and will be transferred through the second conveyor belt.

The transmission direction of the first conveyor belt is opposite to the transmission direction of the second conveyor belt, wherein the transmission path of the first conveyor belt includes the movement path of the feed hopper on the parallel slide rails.

[0046] In a possible implementation of the first aspect, the second conveyor belt and the slicing mechanism work alternately. The transmission speed of the second conveyor belt can be adjusted so that the transmission of the second conveyor belt and the cutting frequency of the cutter of the slicing mechanism move up and down are coordinated, which is beneficial to the uniform thickness of fresh Polygonatum sibiricum slices.

[0047] In a possible implementation of the first aspect, the first conveyor belt and the screening mechanism work alternately, and the polygonatum that does not meet the expected requirements can be screened out in batches, thereby preventing the polygonatum on the first conveyor belt from entering the roller brush during the screening process.

[0082] Example 1

[0083] See also Figures 1 to 10 As shown, this embodiment provides a device for uniformly beveling fresh polygonatum with screening and anti-sticking knife functions, which includes:

[0084] Main frame 1;

[0085] A screening mechanism 2, the screening mechanism 2 is installed on the main frame 1, and is used to screen out target polygonatum with a cross-sectional size that meets preset requirements;

[0086] At least two partitions 41 are located below the screening mechanism 2, a single channel 40 is provided between the at least two partitions 41, the target Polygonatum sibiricum is located in the single channel 40, and the single channel 40 has an inlet and an outlet;

[0087] A limiting piece 4130 is provided on the partition plate 41 and is located at the outlet end;

[0088] A second conveyor belt 3 is arranged on the main frame 1 and is located below the at least two partitions 41. The second conveyor belt 3 can drive the target polygonatum located in the single channel 40 to move from the entry end to the exit end;

[0089] The slicing mechanism 5 is installed on the main frame 1 near the output end, and a three-dimensional coordinate system is established with the plane where the second conveyor belt 3 is located as a horizontal reference plane, wherein the X-axis is the travel direction of the second conveyor belt 3, and the cutter of the slicing mechanism 5 is perpendicular to the horizontal reference plane and the cutter is set at an angle to the X-axis, so as to obliquely slice the target Polygonatum sibiricum.

[0090] According to the device for uniformly beveling fresh Polygonatum with screening and anti-sticking knife functions of the embodiment of the present invention, irregular Polygonatum is pre-screened by a screening mechanism, and target Polygonatum that meets the preset cross-sectional size is screened and enters a single channel, and is transferred to a slicing mechanism for beveling under the action of a second conveyor belt, thereby reducing the warping of Polygonatum and retaining more ingredients. When slicing, the target Polygonatum can be limited from warping by a limit piece set at the outlet of the separation channel, so that the thickness of the slices is uniform, thereby ensuring that the Polygonatum slices have a good slice shape and stable medicinal efficacy.

[0091] It should be noted that in order to enable the slicing mechanism to have an angle adjustment function to meet the needs of bevel cutting at different angles, thereby retaining the effective ingredients to the greatest extent and improving the quality of the polygonatum slices, the slicing mechanism 5 includes:

[0092] A clamping bracket 50, the clamping bracket 50 is fixedly mounted on the main frame 1 at the outlet, and a plurality of single channels 40 are spaced apart to form a separation channel 4. The installation position of the clamping bracket 50 is perpendicular to the outlet of the separation channel 4. The clamping bracket 50 includes a first end face 501 and a cutter replacement opening 502 provided on the first end face 501. The design of the clamping bracket with the cutter replacement opening 502 greatly improves the convenience of cutter replacement.

[0093] Two gear adjustment slots 51, each gear adjustment slot 51 has a plurality of first notches 504 for adjusting angles, and a plurality of elastic clips 503 are respectively arranged on opposite slot walls in each gear adjustment slot 51, a first notch 504 is arranged between adjacent elastic clips on the same slot wall, and a gap is arranged between two opposite elastic clips on different slot walls;

[0094] The adjustment component 52 includes two guide rails 520 and adjustment knobs 521 respectively fixedly connected to the guide rails 520. The guide rails 520 located in the first notch 504 are clamped and fixed by the clamping force between the elastic clips 503. The angle adjustment is achieved by turning the adjustment knob 521 to make the guide rails 520 pass through the elastic clips 503 and switch between the first notch 504.

[0095] A driving assembly 53, wherein the driving assembly 53 is mounted on the guide rail 520 and can move along the guide rail 520 after receiving a control instruction sent by a controller;

[0096] A tool holder 54, wherein the tool holder 54 is fixedly connected to the driving assembly 53 by screws;

[0097] The cutter 55 is detachable and height-adjustable and is mounted on the knife holder 54 . The cutter 55 is perpendicular to the horizontal reference plane and is arranged at an angle to the X-axis.

[0098] It should be noted that the elastic clip 503 is fixedly installed in the groove of the side wall of the clamping bracket 50. When driven by external force, the elastic clip 503 can retract in the direction of the groove and extend when the external force is eliminated. Specifically, the bottom of the elastic clip 503 is connected to the bottom of the groove through a rigid spring. External force acting on the elastic clip 503 can cause the rigid spring to deform, thereby forming a limiting clamping mechanism that is convenient for adjusting the guide rail angle and fixed clamping.

[0099] It should be noted that the driving assembly 53 includes:

[0100] A slider 531, wherein the slider 531 is installed on each guide rail 520;

[0101] A hydraulic pump 532, wherein the hydraulic pump 532 is installed on the main frame 1;

[0102] The oil pipeline 533 is connected to the slider 531 and the hydraulic pump 532 respectively, and the slider 531 is driven to move up and down along the guide rail 520 by hydraulic driving. Specifically, the hydraulic pump 532 connected to the oil pipeline 533 is started to make the slider 531 move up and down. Since the tool clamp 54 is fixed to the slider 531 on the guide rail 520 of the clamping bracket 50, the slider 531 will drive the tool clamp 54 to move up and down, thereby making the cutting knife 55 fixed on the tool clamp 54 move up and down to achieve slicing.

[0103] It should be noted that the driving method of the driving assembly in this embodiment is not limited to hydraulic driving, but can also be cylinder driving, etc.

[0104] It should be noted that, as a further optimization of the above-mentioned slicing mechanism, it is ensured that there is no sticking of the polygonatum during the slicing process, thereby improving the slicing efficiency. The slicing mechanism 5 also includes a peeling mechanism, which includes:

[0105] A deck 56, the deck 56 is fixedly installed between the two guide rails 520, and the deck 56 is provided with a through hole matching the cutter replacement opening 502, so as to facilitate the replacement of the cutter 55;

[0106] The first scraper 57 and the second scraper 58 are respectively arranged on both sides of the cutter 55. The first scraper 57 and the second scraper 58 are respectively fixedly installed at the edges of the deck 56, and the scraping openings of the scrapers face and are close to the cutter 55, and are symmetrically distributed.

[0107] It should be noted that the distance between the blade of the first scraper 57 and the blade of the cutter 55 is in the range of 0 mm to 0.2 mm, which is convenient for the cutter 55 to scrape off the polygonatum slices stuck on the cutter during the withdrawal process after cutting the polygonatum once; the angle between the first scraper 57 and the cutter 55 is in the range of 5° to 30°, which is convenient for effectively scraping off the residual polygonatum slices.

[0108] It should be noted that the distance between the blade of the second scraper 58 and the blade of the cutter 55 is in the range of 0 mm to 0.2 mm, which is convenient for the cutter 55 to scrape off the tail flakes of the polygonatum during the process of retracting the cutter after cutting the polygonatum; the angle between the second scraper 58 and the cutter 55 is in the range of 5° to 30°, which is convenient for effectively scraping off the remaining tail flakes of the polygonatum.

[0109] In order to enable the target polygonatum to be stably conveyed on the second conveyor belt, every two partitions 41 are arranged side by side to form a single channel 40, and the separation channel 4 is spaced apart from the second conveyor belt 3. The single channel 40 has an inlet and an outlet, and the inlet is connected to the main frame 1. The target polygonatum is conveyed from the inlet to the outlet through the second conveyor belt 3. The outlet is provided with a limit piece 4130 to prevent the target polygonatum from tilting when it is beveled. At the same time, there is no need to manually load and place the polygonatum, which reduces the workload;

[0110] Each partition plate 41 includes a first connecting piece 411, a second connecting piece 412 and a third connecting piece 413 which are integrally formed. The first connecting piece 411 corresponds to the inlet end of the single channel 40, and the third connecting piece 413 corresponds to the outlet end of the single channel 40.

[0111] The first contact piece 411 is fixedly mounted on the main frame 1 close to the second conveyor belt 3;

[0112] The third connecting piece 413 has a limiting piece 4130 bent into the single channel 40, wherein the limiting piece 4130 is a tapered sheet metal part that is narrow at the top and wide at the bottom, and is used to prevent the Polygonatum sibiricum in the single channel 40 from warping up during slicing and causing uneven cutting.

[0113] It is worth mentioning that, as a further improvement of the present embodiment, the height of the second connecting piece 412 changes depending on the cross-sectional height of the Polygonatum sibiricum and is not limited to a single value. The first connecting piece 411 and the third connecting piece 413 are respectively arranged on both sides of the second connecting piece 412, and their heights are higher than the second connecting piece 412, which can ensure the stable slicing operation of the Polygonatum sibiricum.

[0114] It should be noted that the spacing within the single channel 40 ranges from 0.8 cm to 1.5 cm, which is convenient for separating a single polygonatum for oblique cutting.

[0115] In order to prevent the end of Polygonatum sibiricum from tilting up during slicing and to ensure that the distance between the cutter and the end of each single channel is appropriate during bevel cutting, the single channel 40 further includes:

[0116] The extension kit 42 is nested on the limiting plate 4130 and can slide along the limiting plate 4130 to adjust the distance between the extension kit 42 and the cutter 55, so as to avoid the situation that the cutter is too far away from the limiting plate due to angle adjustment and cannot limit the tilting of the Polygonatum sibiricum.

[0117] In order to reduce the workload by eliminating the need for manual loading, placement and selection of target polygonatum, the screening mechanism 2 comprises:

[0118] A first driving device 21, wherein the first driving device 21 is fixedly mounted on the main frame 1 located on one side of the second conveyor belt 3, and specifically, the first driving device 21 may be a driving motor or a driving cylinder;

[0119] A connecting rod 22, wherein the connecting rod 22 is coaxially connected to the output shaft of the first driving device 21;

[0120] The side cover 23 is a rectangular frame structure with upper and lower openings, and any side edge is fixedly connected to the connecting rod 22. By setting the interval time for starting the first driving device 21, the connecting rod 22 and the side cover 23 are driven to move, and the irregular polygonatum that cannot pass through the roller brush 26 is screened out and treated as defective products, so as to remove the polygonatum that does not meet the preset requirements, which is conducive to uniform cross-sectional size when the polygonatum is cut;

[0121] It is worth mentioning that the side cover 23 in this embodiment is not limited to the rectangular frame structure, but can also be replaced by other components, such as an I-shaped part composed of two rectangular plates fixed at an interval, the two rectangular plates are fixedly connected by two connecting straight rods, and one of the rectangular plates is fixedly connected to the connecting rod 22 for screening out defective products.

[0122] A second driving device 24, the second driving device 24 is fixedly mounted on the main frame 1 located on one side of the second conveyor belt 3, and is vertically arranged with respect to the first driving device 21, and the second driving device 24 includes a plurality of driving output shafts;

[0123] A plurality of roller brush shafts 25, wherein the plurality of roller brush shafts 25 are respectively connected to the drive output shaft one by one;

[0124] Roller brushes 26, each of which is sequentially mounted on the roller brush shaft 25, and each of which has bristles 261 on its surface. Specifically, the roller brushes 26 are fixed to the roller brush shaft 25 through a hole in the roller brush body, so that the roller brush shaft 25 drives the roller brushes 26 to rotate, and the directions of the roller brush shafts 25 are adjusted so that the directions of two adjacent roller brushes 26 are opposite, so that the polygonatum can fall vertically into the separation channel 4 of the lower layer. The side cover 23 is located at the outer edge of the roller brush 26, and is used to prevent the polygonatum from scattering and falling out of the working area of ​​the roller brush 26;

[0125] When the screening mechanism 2 is in operation, the polygonatum sibiricum falls between the roller brushes 26 below the side cover 23. The target polygonatum sibiricum that meets the preset requirements is brushed off to the separation channel 4 below by the roller brush 26 rotating in the opposite direction, and is transferred for displacement via the second conveyor belt 3. The defective polygonatum sibiricum that does not meet the preset requirements will be pushed out of the working area of ​​the roller brush 26 by the side cover 23 driven by the first driving device 21.

[0126] It should be noted that the first driving device 21 includes but is not limited to a hydraulic push rod or an electric push rod.

[0127] This embodiment provides the following specific experimental examples. Six groups of cut polygonatum samples are taken for comparison by using the present device and the existing slicer, and the following experimental statistical data are obtained, as shown in Table 1:

[0128] Table 1: Comparison table of appearance characteristics of Polygonatum sibiricum slices

[0129]

[0130] It is known from experimental tests that the slices of Polygonatum sibiricum cut by the present application can reduce the warping phenomenon of Polygonatum sibiricum slices while retaining more ingredients, so that the Polygonatum sibiricum slices have a good slice shape and stable medicinal efficacy, and the effect is significant.

[0131] In order to facilitate the centralized collection and reprocessing of defective products, the screening mechanism also includes a defective product discharge trough 27, which is fixedly mounted on the main frame 1 close to the side of the roller brush 26, and the highest point is flush with the upper surface of the roller brush 26, so that the first drive device 21 can drive the side cover 23 to push the defective Polygonatum odoratum that does not meet the preset requirements out of the working area of ​​the roller brush 26 and collect them in a centralized manner.

[0132] It is worth mentioning that the defective products mentioned in this article do not refer to the product quality problems of Polygonatum sibiricum, but refer to Polygonatum sibiricum whose cross-section does not meet the expected requirements. After being collected and manually processed, the Polygonatum sibiricum can also be placed in this device for slicing.

[0133] It should be noted that the preset requirement standard of the target Polygonatum sibiricum means that the cross-section of the Polygonatum sibiricum can be in the range of 0.8 cm to 1.5 cm in diameter, and the calibration and replacement of the preset requirement can be achieved by changing the distance between the two roller brushes 26 rotating in opposite directions.

[0134] It should be noted that the roller brushes 26 near the two sides of the side cover 23 rotate in a direction away from the inner wall of the side cover 23, so as to flip the Polygonatum odoratum that falls between the side cover 23 and the roller brush 26 to between the roller brushes 26 with opposite rotation directions for screening.

[0135] It should be noted that the upper layer of the side cover 23 can be optimized to be a slope to facilitate the Polygonatum odoratum to fall into the roller brush better.

[0136] It should be noted that each partition 41 is located below the central axis of rotation of each roller brush 26, which makes it easy for the Polygonatum sibiricum to fall between the two alternating partitions 41 and will not collide with the second conveyor belt 3 below, causing the cross-section of the cutter 55 to change during cutting, thereby ensuring the uniformity of the slice size and thickness.

[0137] It should be noted that the second driving device 24 has multiple independent driving motors built in, and the rotation directions of two adjacent driving motors are opposite, wherein the speed or rotation direction of the driving motor can be regulated by a controller.

[0138] It should be noted that the spacing between the roller brushes 26 ranges from 4 cm to 5 cm. It is worth mentioning that the spacing between the roller brushes 26 here refers to the spacing between the surfaces of the roller brushes 26, and does not include the spacing between the surface bristles. The bristles 261 on the surface of the roller brush 26 are alternately interspersed.

[0139] It should be noted that the bristles 261 on the roller brush 26 in this embodiment can be made of hard plastic.

[0140] It should be noted that the angle range is 15° to 40°, and the bevel angle is adjusted in steps of 5° to improve the warping phenomenon during slicing.

[0141] Example 2

The feed connecting rod 113 is rotatably connected, and the ends of the feed connecting rod 113 away from the driving rod 112 are respectively fixedly connected to the two sides of the outer wall of the feed hopper 114. The feed hopper 114 is set on parallel slide rails, and the turntable 111 is driven to rotate by the synchronous dual-output drive motor 110, thereby driving the driving rod 112 to rotate, thereby pulling the feed connecting rod 113 and the feed hopper 114 to move back and forth on the parallel guide rails, so that the feed hopper 114 can shake back and forth, so as to achieve vibration and spread the polygonatum in the feed hopper 114, and achieve the effect of uniform feeding;

[0145] The first conveyor belt 12 is arranged on the main frame 1 on the side of the side cover 23, and the transmission direction of the first conveyor belt 12 is opposite to the transmission direction of the second conveyor belt 3, wherein the transmission path of the first conveyor belt 12 includes the moving path of the feed hopper 114 on the parallel slide rail.

[0146] It should be noted that a baffle 1140 is provided in the feed hopper 114, and at least one side of the baffle 1140 is fixedly connected to the inner wall of the feed hopper 114. At least one side of the baffle 1140 and the inner wall of the feed hopper 114 form an inlet groove for the Polygonatum odoratum to pass through, so as to play a role in buffering and uniform feeding when the feeding mechanism is working.

[0147] It should be noted that the first conveyor belt 12 and the second conveyor belt 3 are driven by a dual-output shaft drive motor. Specifically, the dual-output shaft drive motor drives the rotating shaft wheels on each conveyor belt through the drive belt, thereby driving each conveyor belt to rotate.

[0148] Example 3

[0149] This embodiment is further optimized on the basis of the above embodiment. In order to identify the head or tail pieces with too large size difference (sheet cross section), the valve opening and closing control is added on the discharge plate to complete the screening of the head or tail pieces, improve the uniformity of the slice size, and ensure the quality of the slices. A device for uniformly beveling fresh Polygonatum odoratum with screening and anti-sticking knife functions is proposed, which also includes a secondary screening mechanism, which is arranged at the discharge end of the second conveyor belt 3, and includes:

[0150] The mounting bracket 6 is fixedly mounted on the main frame 1 near the discharge end of the second conveyor belt 3.

A plurality of second notches 81 are provided on the surface of the discharge plate 8, and each second notch 81 is matched with an electromagnetic valve 82, so as to facilitate the screening of the head and tail pieces after slicing.

[0153] Multiple detection cameras 9 are installed on the mounting bracket 6, and are used to identify the cross-sectional area information of the Polygonatum sibiricum slices and send it to the controller 7. The controller 7 compares the cross-sectional area of ​​the received Polygonatum sibiricum slices with the pre-input cross-sectional reference value. If it exceeds 70% of the cross-sectional reference value, it is identified as a collectible Polygonatum sibiricum slice. Otherwise, it is identified as a head slice or a tail slice, and the electromagnetic valve 82 and the electric push rod 83 are linked to remove the head slice and the tail slice.

[0154] It should be noted that the lens angles of the multiple detection cameras 9 are adjustable, which is conducive to multi-angle acquisition.
