Description

Technical Field

[0001] The invention relates to the technical field of automatic weighing, in particular to quantitative equipment for fluffy Chinese herbal medicine packets. Background Art

[0002] In the field of Chinese herbal medicine packaging and weighing technology, some Chinese herbal medicines are elastic materials that are "pulled and clumped", such as corn silk, ginseng silk, etc., which are in the form of entangled silk strips, which are relatively messy and fluffy. They are easily squeezed and connected into clumps during storage and transportation. They need to be loosened before packaging before weighing. Due to the special shape of the material and the difficulty in pulling it apart, the traditional practice is to manually pull it apart and then weigh and pack it, which is inefficient. In the automatic packaging and weighing equipment in the prior art, some feeding methods can play a role in breaking up the material to a certain extent in the feeding link, but due to the limitations of the design concept and the device structure, the breaking effect is not good, resulting in poor control of the feeding amount, resulting in low weighing accuracy and poor packaging quality consistency. There is even a problem of material blockage, causing the device to get stuck. And when packaging small packages, due to the light weight of the material, the problem of slipping is prone to occur during the weighing and conveying process. Summary of the invention

DETAILED DESCRIPTION

[0041] The specific implementation of the present invention is described below with reference to the accompanying drawings.

[0042] See also Figure 1 and Figure 2 The fluffy Chinese herbal medicine packet quantitative device of this embodiment includes a conveying chain plate 1, a weighing mechanism and a discharging mechanism arranged in sequence along the feeding direction;

[0043] The conveying chain plate 1 is powered by a transmission chain mechanism, and a stirring and breaking mechanism and a scraping mechanism are sequentially arranged above the conveying chain plate 1 along its conveying direction;

[0044] The stirring and breaking mechanism comprises a housing 7, in which a first fixed shaft 5, a first movable shaft 4 and a second fixed shaft 3 are arranged in parallel in the conveying direction in sequence; the first fixed shaft 5 and the second fixed shaft 3 are fixedly arranged, a plurality of first fixed teeth 8 are distributed along the axial direction on the first fixed shaft 5, and a plurality of second fixed teeth 10 are distributed along the axial direction on the second fixed shaft 3; the first movable shaft 4 is rotatably arranged, and a plurality of first movable teeth 9 are distributed along the axial direction on the first movable shaft 4; the first movable teeth 9 are arranged on both sides of the radial direction of the first movable shaft 4, and are respectively and spaced and cross-distributed with the first fixed teeth 8 and the second fixed teeth 10 adjacent thereto, so that when the first movable shaft 4 rotates, a shearing structure is formed, which can be used to pull and break up agglomerated materials;

[0045] The scraping mechanism includes a second movable shaft 2 which is rotatably arranged, on which a plurality of second movable teeth 12 are distributed along the axial direction, and the second movable teeth 12 extend radially along the second movable shaft 2. The second movable shaft 2 is also provided with a scraper 11 extending radially thereof. When the second movable shaft 2 rotates, a gap is formed between the edge of the scraper 11 and the conveying chain plate 1, and the material passes through the gap to form a thin layer which is output to a subsequent weighing mechanism; the thin layer is small in thickness, so that the material is output more smoothly, and the output amount is also controlled, which is convenient for subsequent accurate weighing;

[0046] The rotation direction of the first movable shaft 4 and the second movable shaft 2 is consistent with the rotation direction of the conveying chain plate 1, and the rotation direction can be set according to actual needs; the rotation direction of this embodiment is as follows Figure 1 , Figure 3 As indicated by the arrow in the middle, it is in a clockwise direction.

[0047] As a preferred method, see Figure 3 The structure of the first fixed tooth 8 includes a first straight tooth 82 and a downwardly curved hook tooth 81; the first straight tooth 82 and the downwardly curved hook tooth 81 are respectively arranged on both sides of the radial direction of the first fixed shaft 5, and the downwardly curved hook tooth 81 is located on the side away from the first movable shaft 4 and is bent downward along the rotation direction of the first movable shaft 4;

[0048] The structure of the second fixed tooth 10 includes a second straight tooth 102 and an upward curved hook tooth 101. The second straight tooth 102 and the upward curved hook tooth 101 are respectively arranged on both radial sides of the second fixed shaft 3. The upward curved hook tooth 101 is located on the side away from the first movable shaft 4 and is bent upward along the rotation direction of the first movable shaft 4.

[0049] When the stirring and breaking mechanism of this embodiment is working, the fluffy agglomerated materials are fed from the top of the cover 7 and fall into the input end of the conveying chain plate 1. As the conveying chain plate 1 is conveyed, it encounters the lower curved hook teeth 81 of the fixed first fixed teeth 8 and moves relative to them. Under the action of the lower curved hook teeth 81, it is pulled apart. If it continues to be conveyed, it will continue to be pulled apart under the action of the first movable teeth 9 rotating relative to the first fixed teeth 8 and the second fixed teeth 10. During the pulling and breaking process, the material is in a state of stirring and tumbling. In this process, the upper curved hook teeth 101 of the second fixed teeth 10, like the lower curved hook teeth 81, "contact linearly" with the material to further pull it apart. On the other hand, it holds the agglomerated materials that have not been completely pulled apart from the upper side to prevent them from turning out and falling onto the conveying chain plate 1.

[0050] This embodiment can meet the quantitative requirements of different material properties by reasonably designing the following parameters. The parameters include: the inclination angle of the conveying chain plate 1 from the input end to the output end; the axial spacing between the first movable tooth 9 and the first fixed tooth 8 and the second fixed tooth 10; the spacing and height of the first fixed axis 5, the first movable axis 4 and the second fixed axis 3 along the conveying direction; and the length of each tooth.

[0051] Preferably, the conveying chain plate 1 of this embodiment is inclined upward at an angle of 30° from the input end to the output end; the setting heights of the first fixed axis 5, the first movable axis 4 and the second fixed axis 3 are increased successively, with a height spacing of 140 mm, and the setting height of the second movable axis 2 is lower than the second fixed axis 3; the axial spacing between the first movable tooth 9 and the adjacent first fixed tooth 8 and the second fixed tooth 10 is 2 to 3 cm.

[0052] As an optional embodiment, a plurality of first baffles 6 are provided on the surface of the conveying chain plate 1 along the conveying direction, and the first baffles 6 are perpendicular to the surface of the conveying chain plate 1. During the conveying process, the first baffles 6 increase the friction between the material and the chain plate, play a role in pushing the material, and prevent the material with low density and light weight from slipping on the conveying chain plate. At the same time, when the amount of material is small, the first baffles 6 also play a role in breaking up the material.

[0053] Through the action of the stirring and breaking mechanism, the materials on the conveying chain plate are basically in a shredded and dispersed state, and the shredded and dispersed materials are further conveyed to the scraping mechanism. The second movable teeth 12 of the scraping mechanism rotate with the second movable shaft 2, further dispersing the materials evenly along the axial direction, and then the scraper 11 passes through the gap formed between the edge of the plate and the conveying chain plate 1 when it rotates, and flattens the evenly dispersed materials, so that the materials are output in a thin layer to the subsequent weighing mechanism.

[0054] Therefore, in this embodiment, by setting up the stirring and breaking mechanism and the scraping mechanism, the material is transported by the conveying chain plate 1, and is fed in whole pieces and loosened in sequence to achieve thin layer output.

[0055] As a preferred embodiment, a rubber strip is provided on the edge of the scraper 11 to play a buffering role and prevent damage to the material.

[0056] As a preferred embodiment, the second movable tooth 12 and the scraper 11 form an angle of 90°.

[0057] As an optional implementation, one end of the second movable shaft 2 is connected to a driving motor for driving the second movable shaft 2 to rotate.

[0058] As an optional implementation, see Figure 4 , both ends of the second moving shaft 2 are respectively provided with adjustment mechanisms, the adjustment mechanisms comprising a mounting frame 19, a bearing seat 18, and an adjustment bolt 20;

[0059] The bearing seat 18 is rotatably matched with the second movable shaft 2;

[0060] The bearing seat 18 and the mounting frame 19 are slidably matched and connected by adjusting bolts 20, so that the bearing seat 18 and the mounting frame 19 that slide into place are locked;

[0061] The direction of the sliding fit is consistent with the direction perpendicular to the plate surface of the conveyor chain plate 1. By sliding the bearing seat 18, the size of the gap formed between the scraper 11 and the conveyor chain plate 1 can be adjusted to control the discharge thickness to meet the needs of different application scenarios.

[0062] Specifically, a driving motor is provided on the mounting frame of the adjustment mechanism located at one end of the second movable shaft 2, and the driving motor is connected to the second movable shaft 2 to drive the second movable shaft 2 to rotate.

[0063] See also Figures 1 to 3 The weighing mechanism is located below the output end of the conveying chain plate 1, and includes a plurality of inclined conveyor belts 13 arranged in parallel, and a weighing bucket 15 arranged below the output end of the plurality of inclined conveyor belts 13;

[0064] A plurality of second baffles 14 are provided on the surface of the inclined conveyor belt 13 along its conveying direction, and the second baffles 14 are perpendicular to the surface of the inclined conveyor belt 13;

[0065] The inclined conveyor belt 13 is arranged to be inclined downward from the input end to the output end.

[0066] The conveying speed of one or more of the plurality of inclined conveyor belts 13 is different from the conveying speed of the remaining belts.

[0067] The horizontal conveyor belt and the second baffle 14 of this embodiment facilitate the smooth conveying of light and thin materials and prevent slipping. The inclined conveyor belt 13 is independently set, and the transmission speed can be controlled according to the feedback of the weighing sensor connected to the weighing bucket 15. When the set weight is not reached, the conveying speed can be accelerated. When it is close to the set weight, all or part of the conveyor belts are slowed down, or part of the conveyor belts are stopped, so as to achieve the purpose of fine-tuning and realize accurate weighing. It is prevented that the weighing weight cannot be accurately controlled due to inertia when conveying at a single speed throughout the whole process.

[0068] See also Figure 1 and Figure 5 , the discharging mechanism includes a horizontal conveyor belt 16, a lower hopper and a pressing piece;

[0069] The two ends of the horizontal conveyor belt 16 are respectively connected to the discharge end of the weighing mechanism (i.e. the outlet of the weighing hopper 15) and the inlet of the lower hopper;

[0070] The lower hopper is provided with two sections connected to each other at the upper and lower sides along the material discharge direction, namely, a feed section 173 and a discharge section 174; the cross section of the feed section 173 gradually decreases from top to bottom, and the longitudinal section is preferably a trapezoid, and the inlet area is larger than the outlet area; the cross section of the discharge section 174 is equal at the upper and lower sides, and the longitudinal section is preferably a rectangle, and the inlet and outlet areas are equal to the outlet area of ​​the feed section 173;

[0071] The material pressing member includes a material pressing plate 172 that can extend into the lower hopper and perform lifting and lowering movements. The area of ​​the material pressing plate 172 is not larger than the outlet area of ​​the feeding section 173.

[0072] The material pressing plate 172 can be specifically arranged at the output end of the lifting cylinder 171, and the lifting cylinder 171 is installed above the lower hopper. When pressing the material, the lifting cylinder 171 is actuated to drive the material pressing plate 172 to move downward, and press the material entering from the inlet of the feeding section 173 downward to prevent the material from being unable to be discharged smoothly due to the resistance of the hopper wall. During the downward pressing process of the material pressing plate 172, the material is compressed because the cross section of the feeding section 173 gradually shrinks from top to bottom, thereby limiting the discharge volume, ensuring the consistency of the discharge volume, and facilitating subsequent packaging.

[0073] In order to increase resistance and prevent fluffy materials from slipping, the surface of the horizontal conveyor belt 16 of this embodiment is provided with a plurality of third baffles 17 along its conveying direction, and the third baffles 17 are perpendicular to the surface of the horizontal conveyor belt 16 .

[0074] This embodiment is particularly suitable for quantitative and fixed-volume discharging of fluffy materials by providing a discharging hopper with a variable cross-section and coordinating the action of a pressing plate. It can effectively prevent the materials from stagnating in the discharging hopper due to their light weight. In addition, the degree of compression of the materials is consistent and the discharging volume is inconsistent through the limitation of the discharging hopper, thereby improving the consistency of the packaged products.

[0075] Those skilled in the art can understand that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions recorded in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
