Technical Field

[0001] This invention relates to the field of capsule manufacturing technology, and more specifically, to a stirring apparatus for preparing empty capsules. Background Technology

[0002] In the production of empty capsules, the uniformity of the gelatin solution is a key factor determining the capsule wall thickness, strength, and molding quality. Traditional stirring devices often use a fixed-angle stirring paddle for unidirectional rotation. This stirring method is prone to laminar flow and dead zones, resulting in uneven mixing of the gelatin solution. Summary of the Invention

The stirring tank includes a stirring motor and a drive shaft. The drive shaft is located in the middle of the inside of the stirring tank and is vertically arranged. The stirring motor drives and connects to the drive shaft. Several stirrers are installed on the outer periphery of the drive shaft. A guide assembly is provided on the inner wall of the stirring tank. The guide assembly includes two parallel guide rails, each including a horizontal section, a rising section, and a falling section. The ends of the stirrers are located between the two guide rails.

[0006] Furthermore, the agitator includes a mounting base, a stirring blade, and a mounting sleeve. The mounting base is installed on the outer periphery of the drive shaft, and a fixed shaft is connected to the side of the mounting base. One end of the stirring blade is installed on the fixed shaft, and the other end of the stirring blade is movably connected to the mounting sleeve. A guide block is provided on the outer periphery of the mounting sleeve, and a guide strip is provided on one side of the two guide rails opposite to each other. The guide block and the guide strip are slidably connected.

[0007] Furthermore, a fixing block is installed on the side of the mounting sleeve near the stirring blade, and a connecting arm is rotatably mounted on the fixing block.

[0008] Furthermore, an installation hole 1 is provided inside the stirring blade, which connects to the end of the stirring blade away from the fixed shaft. A drive shaft 2 is rotatably installed inside the installation hole 1, and a rotating shaft is rotatably installed on the outer periphery of the stirring blade. One end of the rotating shaft extends into the installation hole 1 and is connected to the drive shaft 2 via a bevel gear set. The other end of the rotating shaft is connected to an auxiliary stirring blade. A connector 2 is connected to the end of the drive shaft 2 away from the fixed shaft, and the connector 2 is rotatably connected to the stirring blade. A retainer is provided inside the mounting sleeve, and a connector 1 is rotatably installed inside the retainer. A flexible shaft connects the connector 1 and the connector 2. A drive gear is connected to the connector 1. An upper rack is installed on the side of the upper guide rail facing the lower guide rail, and a lower rack is installed on the side of the lower guide rail facing the upper guide rail. The upper and lower racks are staggered, and the drive gear can mesh with either the upper or lower rack.

[0009] Furthermore, a descending pusher and an ascending pusher are mounted on the outer periphery of the drive shaft. The height of the descending pusher is higher than the highest agitator setting, and the height of the ascending pusher is lower than the lowest agitator setting.

[0010] Furthermore, the bucket lid includes a support base, which is rotatably mounted at the bottom of the bucket lid. An adjustment motor is installed inside the support base. The upper end of a drive shaft is inserted into the support base, and the support base can rotate with the drive shaft. A mounting hole two is opened inside the drive shaft one, and a drive shaft three is rotatably mounted inside the mounting hole two. A driven block is connected to the upper end of the drive shaft three. The adjustment motor drives a linkage block, and the adjustment motor can drive the drive shaft three to rotate through the cooperation of the linkage block and the driven block.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figures 1-6As shown, a stirring device for preparing hollow capsules includes a stirring tank 1 and a lid 7. The lid 7 is installed on the top of the stirring tank 1. The stirring tank 1 includes a stirring motor 2 and a drive shaft 3. The drive shaft 3 is located in the middle of the interior of the stirring tank 1 and is vertically arranged. The stirring motor 2 is located at the bottom of the stirring tank 1 and drives the drive shaft 3. Several stirrers 4 are installed on the outer periphery of the drive shaft 3. A guide assembly 12 is provided on the inner wall of the stirring tank 1. The guide assembly 12 includes two parallel guide rails. The guide rails include a horizontal section 13, an ascending section 14, and a descending section 15. The horizontal section 13, the ascending section 14, and the descending section 15 are sequentially spliced ​​into a ring shape. The end of the stirrer 4 is located between the two guide rails.

[0023] As the stirring motor 2 drives the stirrer 4 to rotate via the drive shaft 3, the height of the stirrer 4 changes as its end moves within the guide rail, causing it to tilt upwards or downwards. The different states of each stirrer 4 create turbulence in the adhesive solution during stirring, disrupting the consistency of the solution's flow and effectively preventing dead zones and laminar flow, thus greatly improving the mixing uniformity and stirring efficiency of the adhesive solution.

[0024] Furthermore, the stirrer 4 includes a mounting base 9, a stirring blade 11, and a mounting sleeve 24. The mounting base 9 is mounted on the outer periphery of the drive shaft 3. A fixed shaft 10 is connected to the side of the mounting base 9. The fixed shaft 10 is perpendicular to the side of the mounting base 9. One end of the stirring blade 11 is mounted on the fixed shaft 10 and can rotate around the fixed shaft 10. The other end of the stirring blade 11 is movably connected to the mounting sleeve 24. A guide block 25 is provided on the outer periphery of the mounting sleeve 24. A guide strip 23 is provided on one side of the two guide rails facing each other. The guide block 25 and the guide strip 23 are slidably connected.

[0025] Furthermore, a fixing block 27 is installed on the side of the mounting sleeve 24 near the stirring blade 11. A connecting arm 28 is rotatably mounted on the fixing block 27. A mounting block 26 is installed at the end of the stirring blade 11 near the mounting sleeve 24. An oblong hole 29 is formed on the mounting block 26. A guide pin 30 is connected to the end of the connecting arm 28 away from the fixing block 27. The guide pin 30 is slidably disposed in the oblong hole 29. This structure realizes the movable connection between the end of the stirring blade 11 and the mounting sleeve 24. When the height of the mounting sleeve 24 changes, the end of the stirring blade 11 can rotate relative to the mounting sleeve 24, thereby maintaining a continuous connection between the two, so that the stirring blade 11 can always drive the mounting sleeve 24 to rotate.

[0026] Furthermore, the stirring blade 11 has a mounting hole 19 inside, which connects to the end of the stirring blade 11 away from the fixed shaft 10. A drive shaft 20 is rotatably mounted inside the mounting hole 19, and a rotating shaft 22 is rotatably mounted on the outer periphery of the stirring blade 11. One end of the rotating shaft 22 extends into the mounting hole 19 and is connected to the drive shaft 20 via a bevel gear set. The other end of the rotating shaft 22 is connected to an auxiliary stirring blade 21. A connector 33 is connected to the end of the drive shaft 20 away from the fixed shaft 10, and the connector 33 is rotatably connected to the stirring blade 11. The mounting sleeve 24 is provided with... A mounting base 31 contains a first connector 32 rotatably mounted inside. A flexible shaft 34 connects the first connector 32 and the second connector 33. The flexible shaft 34 maintains the transmission between the first connector 32 and the second connector 33 when it bends to a certain extent, thereby maintaining the drive of the second drive shaft 20 when the stirring blade 11 rotates relative to the mounting sleeve 24. A drive gear 16 is connected to the first connector 32. An upper rack 17 is mounted on the side of the upper guide rail facing the lower guide rail, and a lower rack 18 is mounted on the side of the lower guide rail facing the upper guide rail. The upper rack 17 and the lower rack 18 are staggered.

[0027] The upper rack 17 and lower rack 18 are staggered vertically and alternately arranged horizontally. The drive gear 16 can mesh with either the upper rack 17 or the lower rack 18. When the drive gear 16 meshes with either the upper rack 17 or the lower rack 18, the rotation direction of the drive gear 16 is opposite, thereby driving the drive shaft 20 to rotate in different directions, which in turn drives the auxiliary stirring blades 21 to rotate in different directions. During the revolution of the stirrer 4, the auxiliary stirring blades 21 can automatically and regularly alternate between forward and reverse rotation, thereby continuously changing the stirring direction of the local adhesive liquid, forming more intense convection and eddies, further enhancing the mixing effect, and is especially suitable for the uniform dispersion of high viscosity or easily stratified materials.

[0028] At any given time, the drive gear 16 can only mesh with one of the upper rack 17 or the lower rack 18, and there will be no mutual interference.

[0029] Furthermore, a descending pusher 5 and an ascending pusher 6 are mounted on the outer periphery of the drive shaft 3. The descending pusher 5 and the ascending pusher 6 are rotatably mounted on the rotating seat 42, which is fixed to the outer periphery of the drive shaft 3. The height of the descending pusher 5 is higher than that of the highest agitator 4, and the height of the ascending pusher 6 is lower than that of the lowest agitator 4. That is, the agitator 4 is located between the descending pusher 5 and the ascending pusher 6. The ascending pusher 6 generates an upward thrust on the adhesive, causing the adhesive to flow upward. The descending pusher 5 generates a downward thrust on the adhesive, causing the adhesive to flow downward. This results in axial flow of the adhesive, which is then agitated by the agitator 4 located between the two. This allows the adhesive at the bottom to mix better with the adhesive at other locations, preventing some substances in the adhesive from settling to the bottom.

[0030] Furthermore, the bucket lid 7 includes a support base 8, which is rotatably mounted on the bottom of the bucket lid 7. An adjustment motor 39 is installed inside the support base 8. The upper end of the drive shaft 3 is inserted into the support base 8. The support base 8 can rotate with the drive shaft 3, which in turn allows the adjustment motor 39 to rotate with the drive shaft 3. The drive shaft 3 has a mounting hole 35 inside, and the upper end of the mounting hole 35 is connected to the upper end of the drive shaft 3. A drive shaft 36 is rotatably mounted inside the mounting hole 35. A driven block 37 is connected to the upper end of the drive shaft 36. The adjustment motor 39 is driven by a linkage block 38. The adjustment motor 39 can drive the drive shaft 36 to rotate through the cooperation of the linkage block 38 and the driven block 37. The lowering pusher 5 and the raising pusher 6 are both connected to an adjustment shaft 43. The end of the adjustment shaft 43 extends into the mounting hole 35 and is connected to a driven bevel gear 44. The drive shaft 36 is connected to a driving bevel gear 45 on its outer periphery. The driven bevel gear 44 meshes with the driving bevel gear 45.

[0031] By adjusting the motor 39 to drive the drive shaft 36 to rotate, the drive shaft 36 drives the adjusting shaft 43 to rotate through the cooperation of the active bevel gear 45 and the driven bevel gear 44, thereby driving the downward pusher 5 and the upward pusher 6 to rotate to adjust the angle, thereby obtaining different downward thrust and upward thrust, thus changing the flow speed of the adhesive in the vertical direction.

[0032] Furthermore, a slide rail 46 is installed at the bottom of the support base 8, and a slider 47 is slidably arranged inside the slide rail 46. Limit blocks 48 are provided at both ends of the slide rail 46, and springs 49 are connected between the two limit blocks 48 and the ends of the slider 47. Several triggers 50 are installed on the side wall of the slide rail 46, and the triggers 50 are arranged radially along the support base 8. The support base 8 rotates with the drive shaft 3, but as the speed of the drive shaft 3 increases, the slider 47 moves outward, gradually contacting the triggers 50. The triggers 50 are signal-connected to the adjusting motor 39. After the triggers 50 are triggered, the adjusting motor 39 runs, thereby driving the drive shaft 36 to rotate, increasing the tilt angle of the rising pusher 6, and accelerating the vertical flow speed of the adhesive, thus matching the high speed of the stirrer 4, achieving automatic matching and synergistic optimization of vertical flow intensity and horizontal stirring intensity.

[0033] Based on the number of triggers 50 that are triggered, the adjustment angle is gradually increased. Each triggered trigger 50 increases the angle of the rising pusher 6 by 6 degrees, thereby gradually increasing the vertical flow speed of the adhesive.

[0034] Furthermore, a slot 40 is provided on the top of the drive shaft 3, and the support base 8 includes a plug 41, which can be inserted into the slot 40 so that the support base 8 can rotate synchronously with the drive shaft 3.

All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
