Description

Technical Field

[0001] The utility model relates to the technical field of glue-making tanks, in particular to a glue-making device for capsule production. Background Art

[0002] The gelling device refers to the use of a gelling tank to evenly dissolve and mix gelatin, plasticizers (such as glycerin), water and other necessary ingredients to form a uniform and consistent gelatin solution, which is the basis for the subsequent production of soft capsule shells.

[0003] In the related technology, heating and stirring in the gelling tank can ensure that all ingredients are fully integrated to avoid clots or uneven distribution, which is crucial to the quality of the capsule shell.

[0004] For example, a chemical glue tank with application number CN202223143644.5 has a tank cover on the tank body, a motor is axially fixedly installed on the top of the tank cover, the output shaft of the motor is connected to the stirring shaft, and by starting the motor, the stirring shaft can stir the tank body.

[0005] In addition, a number of anti-settling blades are connected to the bottom end of the stirring shaft through a connecting plate. The anti-settling blades are evenly distributed along the circumference of the connecting plate, and multiple anti-settling blades extend into the short tube at the discharge port. When the stirring shaft rotates, the anti-settling blades are driven to rotate, and the gelatin in the tank body will not settle in the short tube at the discharge port, thereby avoiding the difference in viscosity between the upper and lower layers of the material in the gelatin tank.

[0006] However, there are still some problems in the actual use of the above patent. For example, only by setting a stirring shaft in the tank body, the stirring method is single, and a stirring blind spot is likely to appear in the tank body. Moreover, due to the temperature difference between the upper and lower parts of the tank body, the single stirring method cannot quickly break the temperature stratification, which affects the rate and uniformity of the chemical reaction during the gelling process. In addition, although the above patent is provided with an anti-sedimentation paddle at the bottom, it can only be used for the short pipe at the discharge port, and cannot play a good role in the dissolution of solid particles in the tank body and the uniform mixing of various components in the liquid. Summary of the invention

[0007] The utility model aims to solve one of the technical problems in the above-mentioned technology at least to a certain extent.

[0008] To achieve the above-mentioned purpose, the first aspect of the utility model proposes a gelling device for capsule production, comprising: a tank body, a tank cover, a stirring device, an eccentric transmission device and an ultrasonic generating rod, wherein the tank cover is detachably arranged on the tank body; the eccentric transmission device is arranged on the tank cover; the stirring device is movably arranged on the tank cover and is connected to the transmission end of the eccentric transmission device to drive the stirring device up and down in the vertical direction, the stirring device comprises a mounting folding plate, a first driving motor, a rotating shaft and a stirring rod, wherein a vertical stabilizing rod is arranged on the tank cover, and the mounting folding plate is slidably arranged on the stabilizing rod; the first driving motor is arranged on one surface of the mounting folding plate, and a slide groove is provided on the other surface of the mounting folding plate, and the transmission end of the eccentric transmission device is slidably arranged in the slide groove; one end of the rotating shaft is connected to the output end of the first driving motor, and the other end passes through the tank cover and extends into the tank body; a plurality of the stirring rods are respectively arranged on the rotating shaft; and a plurality of the ultrasonic generating rods are arranged in a circular shape at the bottom of the tank body.

[0009] In addition, the capsule production device according to the utility model may also have the following additional technical features:

[0010] As a further description of the above technical solution: the eccentric transmission device includes a mounting frame, a second drive motor, a rotating disk and an eccentric rod, wherein the mounting frame is arranged on the tank cover; the second drive motor is installed on the mounting frame; the rotating disk is connected to the output end of the second drive motor; the eccentric rod is eccentrically arranged on the rotating disk, and the eccentric rod is slidably arranged in the slide groove.

[0011] As a further description of the above technical solution: a scraper is provided at the end of the stirring rod, and the scraper is in contact with the inner wall of the tank body. When the stirring rod rotates, the scraper can scrape the inner wall of the tank body to avoid adhesion to the inner wall of the tank body.

[0012] As a further description of the above technical solution: the connection between the rotating shaft and the tank cover is connected by a mechanical seal or a floating seal or a magnetic fluid seal. For example, the mechanical seal is installed at the interface between the rotating shaft and the tank cover, and is composed of a dynamic ring, a static ring, a spring, a sealing ring, etc., wherein the dynamic ring rotates with the rotating shaft, and the static ring is fixed on the tank cover, and a small gap is maintained between the two and a pre-tightening force is applied by the spring to form a stable sealing interface to ensure a continuous sealing effect; for example, the floating seal is composed of one or more floating rings, which can have a certain degree of freedom in the axial direction to adapt to the up and down movement of the rotating shaft. The floating ring relies on the friction between itself and the rotating shaft or the force of the external spring to maintain contact with the surface of the rotating shaft, thereby forming a seal; for example, the magnetic fluid seal uses a magnetic field to control the magnetic liquid to form a sealing film at the sealing interface. This sealing method does not require direct physical contact, so the wear is extremely small, and it is suitable for high-speed, high-temperature, and highly corrosive environments. The magnetic fluid seal can be installed at both ends of the rotating shaft above and below the tank cover, and the magnetic fluid is controlled by the magnetic field to follow the rise and fall of the rotating shaft to maintain the sealing effect.

[0013] As a further description of the above technical solution: the tank body is provided with an inner cavity, and a heat medium inlet and a heat medium outlet connected to the inner cavity are respectively provided on both sides of the tank body. The heat medium is poured into the inner cavity from the heat medium inlet and discharged from the heat medium outlet. The heat medium can be other high-temperature flowing media such as hot water.

[0014] As a further description of the above technical solution: a discharge port is arranged at the bottom of the tank body, and a feed port is arranged on the tank cover.

[0015] As a further description of the above technical solution: the ultrasonic generating rod is externally connected to an ultrasonic generator, and the opening and closing of the ultrasonic generating rod can be controlled by the ultrasonic generator.

[0016] As a further description of the above technical solution: an observation window is also provided on the tank cover to facilitate observation by relevant staff.

[0017] According to the gelling device for capsule production of the utility model, the eccentric transmission device can drive the stirring end of the stirring device to move up and down in the tank body, so that while stirring, the dissolved solid particles and the liquid in the tank body can be stirred up and down, quickly breaking the temperature stratification, and promoting the dissolution of solid particles and the uniform mixing of various components in the liquid, thereby improving the rate and uniformity of chemical reactions in the gelling process. In addition, by arranging a plurality of ultrasonic generating rods arranged in a ring shape at the bottom of the tank body, not only can the deposition of the bottom material be reduced and the uniform heating and mixing of the bottom material be promoted, but also the cavitation effect generated in the liquid can effectively disperse and reduce the particle size, thereby helping to quickly form a more uniform colloidal suspension.

DETAILED DESCRIPTION

[0028] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The following describes the capsule production device according to the embodiment of the utility model in conjunction with the accompanying drawings.

[0030] like Figures 1 to 6 As shown, the gelling device for capsule production of the embodiment of the utility model drives the stirring device 300 to rise and fall through the eccentric transmission device 400, which can realize stirring in multiple places in the tank body 100 and reduce the existence of stirring blind spots. In addition, the lifting stirring device 300 can realize the turning of fixed particles and liquids and improve the uniformity of stirring and mixing. By setting a plurality of ultrasonic generating rods 500 arranged in a circular shape at the bottom of the tank body 100, not only can the sedimentation of the bottom material be reduced, but also the dissolution of solid particles and the mixing of liquids can be made more uniform through the cavitation effect.

[0031] A glue tank with application number CN202223143644.5 (hereinafter referred to as "the patent") is equipped with a motor axially fixed on the top of the tank cover, and the output shaft of the motor is connected to the stirring shaft. The stirring shaft extends to the bottom of the tank body. When working, the motor drives the stirring shaft to rotate, and the stirring blades rotate with the stirring shaft to stir the material. This stirring method is relatively simple and can only stir the material in the tank body horizontally. When the material in the tank body is heated, temperature stratification is likely to occur. Stirring in a single mode cannot quickly break the temperature stratification, and there is a stirring blind spot (for example, between the blades of the stirring shaft arranged from top to bottom), which is not conducive to the rapid mixing of the material.

[0032] The gelling device for capsule production of the utility model drives the stirring device 300 to move up and down through the eccentric transmission device 400, that is, the second drive motor 420 drives the rotating disk 430 to rotate, so that the eccentric rod 440 rotates, and the eccentric rod 440 moves in the slide groove 311, and due to the limiting effect of the stabilizing rod 301, the mounting folding plate 310 is driven to move up and down, so as to drive the stirring device 300 to move up and down. When the stirring device 300 is stirring, the first drive motor 320 drives the rotating shaft 330 to rotate, so that the stirring rod 340 rotates with the rotating shaft 330 to stir the material in the tank body 100. When the rotating shaft 330 is lifted or lowered, the stirring blade is lifted or lowered in the process of axial rotation, so that the material in the tank body 100 is turned over, so as to quickly break the temperature stratification and stir evenly.

[0033] The patent only has a plurality of anti-settling blades connected to the bottom end of the stirring shaft through a connecting plate. The anti-settling blades are evenly distributed along the circumference of the connecting plate, and multiple anti-settling blades extend into the short tube of the discharge port. The anti-settling blades at the bottom end of the stirring shaft stir and mix the gelatin accumulated in the short tube of the discharge port. Although it can prevent the sedimentation of some materials to a certain extent, it is limited to the short tube of the discharge port, and the effect of preventing material sedimentation is not good.

[0034] The capsule production gelling device of the utility model has a plurality of ultrasonic generating rods 500 arranged in a ring shape at the bottom of the tank body 100. Through the action of the ultrasonic generating rods 500, the piezoelectric element or magnetostrictive element inside thereof generates mechanical vibration under the action of high-frequency alternating current, and then emits ultrasonic waves to the liquid medium in the tank body. When ultrasonic waves propagate in the liquid, a strong cavitation effect is generated, that is, tiny bubbles are formed and exploded in the liquid. This process generates a strong shear force and local high temperature on the particles in the liquid, which helps to accelerate the dispersion, emulsification and dissolution of the substance. The plurality of ultrasonic generating rods 500 arranged in a ring shape can act on a wider range of materials, can reduce the sedimentation of materials in a wider range, and can also accelerate the uniform mixing of materials.

[0035] The ultrasonic wave generating rod 500 is arranged at the bottom of the tank body 100, so as to make full use of the cavitation effect of the ultrasonic wave, which acts on the colloid from the bottom of the tank body 100 upwards, accelerates the dissolution and mixing of the solid particles, and reduces the formation of bottom precipitation. The arrangement of the ultrasonic wave at the bottom of the tank body 100 helps to form a uniform ultrasonic field in the entire tank body 100, especially for materials with high viscosity or containing large solid particles, which can effectively improve the gelling efficiency and mixing uniformity. At the same time, a stirring device 300 that can be raised and lowered and moved is arranged in the gelling tank, which can further enhance the macroscopic mixing of the materials and ensure that the areas that are not affected by the ultrasonic wave can also be fully stirred. The stirring device 300 can break up larger aggregates through mechanical movement, promote contact and exchange between materials, complement the microscopic effect of the ultrasonic wave, and jointly accelerate the gelling process.

[0036] In summary, according to the capsule production gelling device of the embodiment of the utility model, the eccentric transmission device 400 can drive the stirring end of the stirring device 300 to move up and down in the tank body 100, so that while stirring, the dissolved solid particles and the liquid in the tank body 100 can be stirred up and down, and the temperature stratification can be quickly broken, and the dissolution of solid particles and the uniform mixing of various components in the liquid can be promoted, and the rate and uniformity of chemical reactions in the gelling process can be improved. In addition, by arranging a plurality of ultrasonic generating rods 500 arranged in a ring at the bottom of the tank body 100, not only can the deposition of the bottom material be reduced and the uniform heating and mixing of the bottom material be promoted, but also the cavitation effect generated in the liquid can effectively disperse and reduce the particle size, which helps to quickly form a more uniform colloidal suspension.
