Description

Technical Field

[0001] The invention relates to the technical field of natto and red yeast rice capsules, in particular to a preparation method of natto and red yeast rice capsules. Background Art

[0002] Natto is made by adding Bacillus natto to steamed soybeans and fermenting them. A large amount of active substances are generated during the fermentation process, and long threads can be pulled out after stirring. The nutrient that can lower blood lipids, nattokinase, is hidden in these "long threads". Nattokinase contains Bacillus natto and high elastase. After being absorbed by the human body, it can reduce blood viscosity, improve blood circulation, soften and increase blood vessel elasticity, thereby effectively lowering blood sugar and blood lipid levels in the body, achieving the effect of assisting in lowering blood sugar. Red yeast rice originally grew in various dairy products in nature, and was later fermented on japonica rice by Monascus. Its main functional ingredient is lovastatin. Researchers have found that lovastatin can not only block cholesterol synthesis, but also stimulate and accelerate the removal of cholesterol, as well as increase the synthesis of low-density lipoprotein receptors, which can play a role in lowering blood lipids. In addition, capsules made from it also have the effect of clearing turbidity and lowering lipids, and can effectively dissolve blood clots.

[0003] Patent document CN104651285A discloses a preparation method and application of red yeast rice natto powder and its microcapsule preparation. The red yeast rice waste residue remaining after the extraction of red yeast rice pigment is used as the main culture medium, and Bacillus subtilis natto subspecies is inoculated and fermented to produce red yeast rice natto powder. The red yeast rice natto powder has a lipid-lowering effect and can be used as a food or food additive to prepare food or health food for preventing middle-aged and elderly diseases such as atherosclerosis.

[0004] However, during actual use, the inventors found that during the capsule preparation process, the traditional processing method is to add drug powder into the capsule body and match the empty capsule cap with the capsule body to form a capsule. In this way, the interior of the capsule cannot be completely filled with drug powder, which will cause the capsule to be larger in size. On the one hand, the larger capsule is not conducive to the user's taking, and on the other hand, the larger capsule will also increase the production cost of the capsule. Summary of the Invention

[0005] The purpose of the present invention is to address the shortcomings of the existing technology. By setting up a method for preparing natto and red yeast rice capsules, the method includes a powder filling process, a flattening process, a film coating process and a packaging process. When preparing the capsule, the powder filling mechanism can be used to fill the capsule body and the interior of the capsule cap with medicinal powder at the same time. Then, the flattening mechanism flattens the powder inside the capsule cap and applies a sticky adhesive to the inner side of the capsule cap at the upper end of the powder. Then, the unwinding device transports the shielding film to the upper surface of the capsule cap and cooperates with the cutting mechanism to cut the shielding film into a shape suitable for the capsule cap, and presses the cut shielding film on the inner side of the capsule cap coated with the adhesive. After the adhesive is cooled and shaped, the sealing of the medicinal powder inside the capsule cap can be achieved.

[0026] Beneficial effects of the present invention:

[0027] (1) The present invention provides a method for preparing natto and red yeast rice capsules, which includes a powder filling process, a flattening process, a film coating process, and a packaging process. When preparing the capsule, the powder filling mechanism can be used to fill the capsule body and the inside of the capsule cap with medicinal powder at the same time. Then, the flattening mechanism flattens the powder inside the capsule cap, and applies a sticky adhesive to the inside of the capsule cap at the upper end of the powder. Then, the unwinding device transports the shielding film to the upper surface of the capsule cap and cooperates with the cutting mechanism to cut the shielding film into a shape that matches the capsule cap, and presses the cut shielding film onto the inside of the capsule cap coated with the adhesive. After the adhesive is cooled and shaped, the medicinal powder inside the capsule cap can be sealed. Finally, the capsule cap and the capsule body can be combined and packaged. The capsule prepared by the above method is completely filled with medicinal powder. Therefore, under the premise that the capsule has the same medicinal powder inside, the production size of the capsule can be reduced compared with the traditional processing method. On the one hand, the smaller capsule is more convenient for users to take. On the other hand, the smaller capsule uses less raw materials, thereby reducing the production cost of the enterprise.

[0028] (2) In the present invention, a flattening mechanism is provided to cooperate with a coating mechanism. After the powder filling mechanism injects the powder into the interior of the capsule cap, the first lifting unit in the flattening mechanism drives the pressing block to flatten the powder in the capsule cap. On the one hand, the powder is flattened inside the capsule cap to avoid contact between the coating roller in the coating mechanism and the powder, thereby affecting the normal use of the coating roller. On the other hand, after the powder is flattened, the powder inside the capsule cap and the capsule body can be completely filled in the interior of the capsule after the capsule cap is sealed with the capsule body, thereby improving the utilization rate of the internal space of the capsule.

[0029] (3) In the present invention, a cutting mechanism is provided to cooperate with a coating mechanism. The coating mechanism coats the inner side of the capsule cap with a sticky adhesive. Then, the cutting component in the cutting mechanism cuts the shielding film into the shape of the capsule cap. After the cutting is completed, the pressing component drives the cut shielding film into the interior of the capsule cap and presses the shielding film and the medicine powder in the capsule cap together. At the same time, the outermost shielding film is tightly attached to the inner side of the capsule cap under the action of the adhesive. In this way, the shielding film can prevent the medicine powder from falling out after being fixed inside the capsule cap. Therefore, the capsule cap can be turned over when it is subsequently packaged with the capsule body, thereby solving the technical problem that the interior of the traditional capsule cap cannot be filled with medicine powder.

[0030] (4) In the present invention, a transfer mechanism is provided to cooperate with the second conveying mechanism. After the inside of the capsule cap is filled with medicine powder and covered with a shielding film, the driving component in the transfer mechanism drives the clamping component to move to the placement component in the second conveying mechanism. Then the clamping component clamps the placement component and synchronously lifts the placement component together with the capsule cap on its upper end and transfers it to the first conveying mechanism. During the transfer process, the clamping component works and can drive the placement component to rotate 180°, so that the capsule cap in the placement component and the capsule body in the first conveying mechanism are arranged relative to each other. Finally, the driving component drives the clamping component and the placement component to descend so that the capsule cap and the capsule body can complete the packaging work. The degree of automation is high and it is easy to use.

[0031] In summary, the device has the advantages of reducing the production size of capsules, facilitating users' consumption, and reducing the production costs of enterprises. It is particularly suitable for the field of natto and red yeast rice capsule technology. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the accompanying drawings.

[0051] Example 1

[0052] like Figure 1-Figure 4 As shown, a method for preparing natto red yeast rice capsules comprises the following steps:

[0053] Step 1, powder filling process, separating the capsule body 110 and the capsule cap 120 in the capsule shell 100, then placing the capsule body 110 into the first conveying mechanism 1 and cooperating with the powder filling mechanism 2 to complete the powder filling work of the capsule body 110, and at the same time placing the capsule cap 120 into the second conveying mechanism 3 and cooperating with the powder filling mechanism 2 to complete the powder filling work of the capsule cap 120;

[0054] Step 2: Flattening process: the second conveying mechanism 3 drives the capsule cap 120 to move and cooperates with the flattening mechanism 4 to flatten the powder inside the capsule cap 120, and at the same time cooperates with the coating mechanism 5 to apply the sticky adhesive to the inner wall of the capsule cap 120;

[0055] Step 3, the film coating process, the unwinding device 200 conveys the shielding film 130 to the upper surface of the capsule cap 120 and cooperates with the cutting mechanism 6 to cut the shielding film 130 into a shape that matches the capsule cap 120, and then presses the shielding film 130 into the interior of the capsule cap 120;

[0056] In step 4, the packaging process, the transfer mechanism 7 is used to combine the capsule cap 120 and the capsule body 110 completed in step 3 and complete the packaging of the capsule shell 100.

[0057] In this embodiment, a method for preparing natto red yeast rice capsules is provided, including a powder filling process, a flattening process, a film coating process, and a packaging process. When preparing the capsule, the powder filling mechanism 2 can be used to simultaneously fill the capsule body 110 and the interior of the capsule cap with medicinal powder, and then the flattening mechanism 4 flattens the powder inside the capsule cap 120, and applies a sticky adhesive to the inner side of the capsule cap 120 at the upper end of the powder. Then, the unwinding device 200 conveys the shielding film 130 to the upper surface of the capsule cap 120 and cooperates with the cutting mechanism 6 to cut the shielding film 130 into a shape that matches the capsule cap 120, and the cut The shielding film 130 is pressed onto the inner side of the capsule cap 120 coated with the adhesive, and then the adhesive is cooled and formed, thereby sealing the medicine powder inside the capsule cap 120. Finally, the capsule cap 120 and the capsule body 110 are combined and packaged. The capsules prepared by the above method are completely filled with medicine powder. Therefore, under the premise that the capsules have the same medicine powder inside, the production size of the capsules can be reduced compared with traditional processing methods. On the one hand, smaller capsules are more convenient for users to take. On the other hand, smaller capsules use less raw materials, thereby reducing the production costs of the enterprise.

[0058] Example 2

[0059] like Figure 3-Figure 5As shown, a production device for a method of preparing natto red yeast rice capsules, the second conveying mechanism 3 includes a placement component 31 for placing the capsule cap 120, a bearing component 32 for supporting the conveying and placing component 31 and driving the placing component 31 to rotate, and a conveying component 33 for driving a plurality of the bearing components 32 to move;

[0060] The placement assembly 31 includes an upper placement plate 311 with a plurality of through holes 3111 and a lower placement plate 312 detachably provided with the placement plate and used to support the bottom of the capsule cap 120 ;

[0061] The supporting assembly 32 includes a fixed plate 321 arranged on the conveying assembly 33, a first driving unit 322 arranged on the fixed plate 321 and used to drive the placement assembly 31 to rotate, and a supporting plate 323 fixedly arranged on the upper end of the fixed plate 321 and matched with the lower placement plate 312.

[0062] In this embodiment, by setting the placement component 31 to cooperate with the supporting component 32, the capsule cap 120 can be placed inside the placement component 31, and the capsule cap 120 can also be driven to rotate under the drive of the supporting component 32, thereby facilitating subsequent processing of the capsule cap 120.

[0063] In detail, when in use, first fix the upper placing plate 311 and the lower placing plate 312 to be connected and place the placing component 31 on the supporting component 32, so that the first driving unit 322 and the placing component 31 are matched. When it is necessary to control the rotation of the placing component 31, control the first driving unit 322 to work and drive the upper placing plate 311 and the lower placing plate 312 to rotate. The upper placing plate 311 and the lower placing plate 312 are fixedly connected and will rotate on the supporting plate 323 to ensure the stability of the rotation.

[0064] It should be noted that the upper placement plate 311 and the lower placement plate 312 can be fixedly connected to each other by, but not limited to, bolt connection. Before placing the upper placement plate 311 and the lower placement plate 312 on the carrier assembly 32, it is necessary to first fix the upper placement plate 311 and the lower placement plate 312 together. After the capsule cap 120 and the capsule body 110 are completely packaged, the lower placement plate 312 is removed and all the capsules are taken out. The above steps are all prior art and will not be repeated here.

[0065] The structures of the first conveying mechanism 1 and the second conveying mechanism 3 are basically the same. The difference is that the placement component 31 in the first conveying mechanism 1 only needs to be provided with an upper placement plate 311 for carrying the capsule body 110. In the production and processing of the capsule body 110, only the powder filling mechanism 2 needs to be provided next to the first conveying mechanism 1. It should be noted that the powder in the capsule body 110 needs to be flush with the uppermost end of the capsule body 110 to facilitate subsequent cooperation with the capsule cap 120.

[0066] In this embodiment, the upper edge of the capsule cap 120 or the capsule body 110 is flush with the uppermost end of the through hole 3111 .

[0067] Further, if Figure 6-Figure 7 As shown, the flattening mechanism 4 includes a first lifting unit 41 provided at the upper end of the placement component 31, a support plate 42 provided at the lower end of the first lifting unit 41, and a plurality of pressing blocks 43 provided at the lower end of the support plate 42 and corresponding to the through holes 3111 respectively;

[0068] The smearing mechanism 5 includes a second lifting unit 51 provided at the upper end of the placement assembly 31, a liquid storage tank 52 provided at the lower end of the second lifting unit 51, and a plurality of smearing rollers 53 provided at the lower end of the liquid storage tank 52 and corresponding to the through holes 3111 respectively.

[0069] The flattening mechanism 4 and the smearing mechanism 5 are both arranged on the second conveying mechanism 3 via a support frame 54 .

[0070] In this embodiment, a flattening mechanism 4 is provided to cooperate with the smearing mechanism 5. After the powder filling mechanism 2 injects the powder into the interior of the capsule cap 120, the first lifting unit 41 in the flattening mechanism 4 drives the pressing block 43 to flatten the powder in the capsule cap 120. On the one hand, the powder is flattened inside the capsule cap 120 to avoid contact between the smearing roller 53 in the smearing mechanism 5 and the powder, thereby affecting the normal use of the smearing roller 53. On the other hand, after the powder is flattened, the powder can be completely filled in the capsule after the capsule cap 120 is encapsulated with the capsule body 110, thereby improving the utilization rate of the internal space of the capsule.

[0071] In detail, during operation, the conveying component 33 drives the placement component 31 to move to the lower end of the flattening mechanism 4 and the smearing mechanism 5, and then the conveying component 33 stops working. At this time, the first driving unit 322 is controlled to work and drive the placement component 31 to rotate intermittently. During the period when the placement component 31 stops rotating, the first lifting unit 41 drives the support plate 42 and the multiple pressing blocks 43 at the lower end of the support plate 42 to press down and flatten the powder inside the capsule cap 120. As the placement component 31 rotates, when the first group of flattened capsule caps 120 rotates to the lower end of the smearing mechanism 5, the second lifting unit 51 works simultaneously with the first lifting unit 41. The second lifting unit 51 drives the liquid storage tank 52 and the smearing roller 53 provided at its lower end to extend into the interior of the capsule cap 120 and smear the inner wall of the capsule cap 120. After reciprocating like this, until the powder inside all capsule caps 120 is flattened and the interior of all capsule caps 120 is smeared with adhesive.

[0072] It should be noted that after the smear roller 53 enters the interior of the capsule cap 120, the lowermost end of the smear roller 53 does not contact the uppermost end of the medicine powder inside the capsule cap 120, thereby preventing the powder from adhering to the smear roller 53;

[0073] The upper end of the smear roller 53 in the present invention extends into the interior of the liquid storage tank 52, and the adhesive inside the liquid storage tank 52 can flow along the smear roller 53 to the outside of the lower end of the smear roller 53 to ensure that there is adhesive on the smear roller 53 at all times. In order to ensure the viscosity and food safety of the adhesive, the adhesive can be but is not limited to edible polysaccharide glue.

[0074] Further, if Figure 8 As shown, the cutting mechanism 6 includes a third lifting unit 61 arranged at the upper end of the placement component 31, a mounting plate 62 arranged at the lower end of the third lifting unit 61, several groups of cutting components 63 connected to the mounting plate 62 and respectively corresponding to the through holes 3111, several groups of clamping components 64 connected to the mounting plate 62 and arranged inside the cutting components 63, and a control component 65 cooperated with the clamping component 64 for controlling the delayed operation of the clamping component 64.

[0075] In this embodiment, a cutting mechanism 6 is provided to cooperate with a coating mechanism 5, and the coating mechanism 5 coats the inner side of the capsule cap 120 with a sticky adhesive, and then the cutting component 63 in the cutting mechanism 6 cuts the shielding film 130 into a shape that matches the capsule cap 120. After the cutting is completed, the pressing component 64 drives the cut shielding film 130 into the interior of the capsule cap 120 and presses the shielding film 130 and the powder in the capsule cap 120 together. At the same time, the outermost shielding film 130 is tightly attached to the inner side of the capsule cap 120 under the action of the adhesive. In this way, the shielding film 130 can prevent the powder from falling out after being fixed inside the capsule cap 120. Therefore, the capsule cap 120 can be flipped when it is subsequently packaged with the capsule body 110.

[0076] In detail, during operation, the conveying component 33 drives the placement component 31 to move to the lower end of the cutting mechanism 6, and then the unwinding device 200 conveys the shielding film 130 to the upper surface of the capsule cap 120 (preferably, the shielding film 130 is arranged close to the upper surface of the upper placement plate 311), and then the third lifting unit 61 descends and drives the cutting component 63 to complete the cutting of the shielding film 130, and then drives the clamping component 64 to send the cut shielding film 130 into the interior of the capsule cap 120 and bond it together with the adhesive applied on the upper side wall of the capsule cap 120.

[0077] It should be noted that a reeling device is provided on the other side of the unwinding device 200 relative to the conveying assembly 33. The reeling device is used to reel in the waste of the masking film 130 remaining after cutting. The reeling device is a common structure and is not shown in the figure.

[0078] The shielding film 130 used in the present invention is an edible film, which can be a polysaccharide edible packaging film, a protein edible film, or a composite edible film.

[0079] Further, if Figures 9-12 As shown, the cutting assembly 63 includes an annular cutter head 631 fixedly connected to the mounting plate 62 and a plurality of triangular cutter heads 632 integrally provided with the annular cutter head 631 and arranged in an array along the circumferential direction of the annular cutter head 631;

[0080] The pressing assembly 64 includes a buffer spring 641 fixedly connected to the mounting plate 62, a pressing block 642 provided at the lower end of the buffer spring 641, and a connecting rod 643 provided between two adjacent groups of the pressing assemblies 64;

[0081] The upper placement plate 311 is provided with cutting grooves 3112 at positions corresponding to the annular cutter head 631 and the triangular cutter head 632;

[0082] The control assembly 65 includes a downward pressure rod 621 connected to the mounting plate 62, a sliding plate 651 cooperating with the downward pressure rod 621, a rotating plate 652 rotatably connected to the sliding plate 651 and cooperating with the connecting rod 643, and a supporting member 653 for supporting the sliding plate 651 and arranged on the second conveying mechanism 3, and a plurality of return springs 654 are arranged between the sliding plate 651 and the supporting member 653.

[0083] In this embodiment, the third lifting unit 61 first drives the mounting plate 62 downward and simultaneously drives the annular cutter head 631 and the plurality of triangular cutter heads 632 downward to cut the shielding film 130. The cut shielding film 130 includes a central portion 131 of the same size as the through hole 3111 and a plurality of side portions 132 arranged on the outside of the central portion 131 (the side portions 132 are cut to ensure that the plurality of side portions 132 can completely fit tightly against the upper inner wall of the capsule cap 120 to avoid wrinkles on the side portions 132, which would affect the normal assembly of the capsule cap 120 and the capsule body 110). When the pressing block 642 in the pressing assembly 64 is about to contact the shielding film 130, the connecting rod 643 first contacts the rotating plate 652 and stops moving downward under the limiting action of the rotating plate 652. At this time, the pressing block 642 drives the buffer spring 641 to be compressed. At the same time, the lower pressing rod 621 provided on the mounting plate 62 abuts against the uppermost end of the sliding plate 651. When the cam 652 is in the closed position, the spring 654 of the second stop 643 is engaged with the stop 644, and the stop 644 is engaged with the stop 645.

[0084] It should be noted that a limit member is provided on the rotating plate 652. When the connecting rod 643 descends, the rotating plate 652 will not rotate downward along with the connecting rod 643. When the connecting rod 643 rises from bottom to top, the rotating plate 652 will rotate upward driven by the connecting rod 643. When the connecting rod 643 detaches from the rotating plate 652, the rotating plate 652 and the sliding plate 651 are automatically reset.

For simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that:

[0087] Furthermore, the transfer mechanism 7 includes a driving assembly 71, a transfer plate 72 disposed on the driving assembly 71, and a clamping assembly 73 disposed on the transfer plate 72 and used to clamp the placement assembly 31. The clamping assembly 73 can also drive the placement assembly 31 to rotate to achieve the matching of the capsule cap 120 and the capsule body 110.

[0088] The driving assembly 71 includes a second driving unit 711, a bevel gear pair 712 connected to the second driving unit 711, a threaded rod 713 connected to the bevel gear pair 712, a sleeve 714 sleeved on the outside of the threaded rod 713 and having a guide groove 715, and a sliding block 716 matched with the threaded rod 713 and disposed inside the guide groove 715. The sliding block 716 is fixedly connected to the transfer plate 72.

[0089] The clamping assembly 73 includes a third driving unit 731 fixedly disposed on the transfer plate 72, a driving rack 732 connected to the third driving unit 731, a rotating gear 733 cooperating with the driving rack 732, a rotating ring 734 coaxially disposed with the rotating gear 733, a fourth driving unit 735 fixedly disposed on the rotating ring 734, and a clamping claw 736 cooperating with the fourth driving unit 735;

[0090] The clamping assembly 73 is provided with two groups, and the upper placement plate 311 is provided with two groups of protrusions 3113 that cooperate with the clamping claws 736.

[0091] It is worth mentioning that by setting up a transfer mechanism 7 to cooperate with the second conveying mechanism 3, after the interior of the capsule cap 120 is filled with medicine powder and covered with a shielding film 130, the driving component 71 in the transfer mechanism 7 will drive the clamping component 73 to move to the placement component 31 in the second conveying mechanism 3, and then the clamping component 73 will clamp the placement component 31 and synchronously lift the placement component 31 together with the capsule cap 120 on its upper end and transfer it to the first conveying mechanism 1. During the transportation process, the clamping component 73 works and can drive the placement component 31 to rotate 180°, so that the capsule cap 120 in the placement component 31 is arranged relative to the capsule body 110 in the first conveying mechanism 1. Finally, the driving component 71 drives the clamping component 73 and the placement component 31 to descend so that the capsule cap 120 and the capsule body 110 complete the packaging work.

[0092] In detail, after the shielding film 130 is sent into the interior of the capsule cap 120, the capsule cap 120 needs to be sent into the freezing chamber 300 for freezing, so that the adhesive solidifies to ensure the stability of the bonding between the shielding film 130 and the capsule cap 120. When the capsule cap 120 is removed from the freezing chamber 300, the capsule cap 120 and the capsule body 110 can be packaged. The specific operation is as follows: first, the second driving unit 711 works and drives the threaded rod 713 to rotate through the bevel gear pair 712. After the threaded rod 713 rotates, it drives the sliding block 716 to move on the threaded rod 713. At the same time, the sliding block 716 will move along the guide groove 715. At the same time, the transfer plate 72 connected to the sliding block 716 will drive the clamping assembly 73 to move to the position of the upper placement plate 311. When the clamping claw 736 moves After reaching the position of the protrusion 3113, the fourth drive unit 735 works and drives the clamping claw 736 to clamp the protrusion 3113. At this time, the clamping component 73 completes the clamping work of the placement component 31. Then the second drive unit 711 works again and drives the transfer plate 72 and the clamping component 73 to rise and move the clamping component 73 to the position of the first conveying mechanism 1. During the movement, the third drive unit 731 works and drives the driving rack 732 to move. The driving rack 732 will drive the rotating gear 733 to rotate, thereby driving the fourth drive unit 735 and the clamping claw 736 to rotate, and finally drives the placement component 31 to rotate 180°. At this time, the capsule cap 120 in the upper placement plate 311 is set downward, and can complete the docking and packaging work with the capsule body 110 in the first conveying mechanism 1.

[0093] It should be noted that when the sliding block 716 is in the vertical groove 7151 in the guide groove 715, the sliding block 716 will perform a lifting movement. When the sliding block 716 is in the horizontal groove 7152 in the guide groove 715, the sliding block 716 will rotate along with the threaded rod 713. Therefore, by controlling the forward and reverse rotation of the second drive unit 711, the sliding block 716 can be moved at will. For this purpose, two groups of vertical grooves 7151 are provided, and the two groups of vertical grooves 7151 are respectively provided corresponding to the first conveying mechanism 1 and the second conveying mechanism 3.
