Description

Technical Field

[0001] This application relates to the field of pharmaceutical machinery technology, and more specifically, to an extrusion apparatus. Background Technology

[0002] Extrusion is a process in which powdered materials are mixed with suitable wetting agents and binders to form a soft material, which is then processed into granules of a certain shape and size using an extrusion device. In recent years, the pharmaceutical, chemical, materials, and food industries have been using this process to process materials. Irregular granules can be directly extruded, or strips can be extruded and then processed into short cylindrical granules or spherical pellets through subsequent shearing or rounding processes.

[0003] Samples extruded by equipment with different extrusion principles will have certain differences. Common extrusion equipment includes planetary extrusion, etc. The extrudate is a continuous strip that is not easy to break and fall in time, which will cause it to accumulate and hinder the smooth extrusion of subsequent materials. Utility Model Content

[0004] The purpose of this application is to provide an extrusion device that enables the extrudate to detach in a timely manner, avoids accumulation, and ensures smooth extrusion.

[0005] In a first aspect, embodiments of this application provide an extrusion apparatus, comprising: an extrusion mechanism including an extrusion assembly and an extrusion orifice plate, the extrusion assembly being configured to crush material to form an extrudate, the extrusion orifice plate being connected to the extrusion assembly for the outflow of the extrudate; and a shearing mechanism including a drive structure and a shearing assembly, the drive structure being connected to the shearing assembly, the shearing assembly being disposed outside the extrusion orifice plate for shearing the extrudate.

[0006] In the above process, the extrusion orifice plate is connected to the extrusion assembly, and the drive structure is connected to the shearing assembly. The shearing assembly is located outside the extrusion orifice plate, so that after the material enters the interior of the extrusion assembly, the extrusion assembly crushes it, and the crushed material forms an extrudate. The extrusion assembly expels the extrudate from the extrusion orifice plate. Then, the drive structure drives the shearing assembly to rotate, so as to cut the extrudate from the extrusion orifice plate at a uniform speed, which can obtain particles of uniform length and quickly carry them away from the extrusion orifice plate, avoiding accumulation and ensuring the smooth extrusion of the extrudate.

[0007] In some embodiments, the shearing assembly includes a connector and a shearing member, the connector connecting the shearing member and the shearing member extending to the extrusion plate from the side opposite to the connector.

[0008] In the above process, the shearing component is connected to the connecting component, and the driving structure drives the shearing component to rotate along the outer edge of the extrusion plate. As a result, when the extrusion assembly extrudes the extrudate from the extrusion plate, the shearing component can cut it off at a uniform speed, thereby obtaining particles of uniform length. This avoids particle accumulation and adhesion to the extrusion assembly or extrusion plate. Furthermore, the particles obtained by shearing do not need to be granulated again to obtain particles of the required size, which can avoid material loss and reduce production costs.

[0009] In some embodiments, the shearing elements are spaced apart from the extrusion plate.

[0010] In the above process, by spacing the shearing component with the extrusion orifice plate, not only can friction between the shearing component and the extrusion orifice plate be avoided to obtain particles of the required size, but the shearing component can also effectively shear the extrudate under the action of the driving structure, avoiding the accumulation of the extrudate and ensuring the smoothness of the extrudate extrusion.

[0011] In some embodiments, the connector includes a first connector and a second connector. The first connector has a mounting groove along its length. One end of the second connector is connected to the mounting groove, and the other end is detachably connected to the shearing member.

[0012] In the above implementation process, the second connector is connected to the mounting groove of the first connector, so that the second connector can be adjusted relative to the first connector through the mounting groove, thereby adjusting the position of the shearing component relative to the extrusion plate, improving the shearing effect. At the same time, the shearing component can be disassembled and connected to the second connector, which is convenient for the replacement and maintenance of the shearing component and improves efficiency.

[0013] In some embodiments, the second connector is provided with an inclined portion distributed at a preset angle, the inclined portion being provided with a snap-fit ​​cavity, and a portion of the shearing member is disposed in the snap-fit ​​cavity. By installing the shearing member in the snap-fit ​​cavity, the shearing member is inclined, which facilitates the shearing of the extrudate and avoids extrudate accumulation.

[0014] In some embodiments, a plurality of shearing components are configured, and the plurality of shearing components are spaced apart along the periphery of the extrusion component. This enables effective shearing of the extrudate around the periphery of the extrusion plate, preventing the extrudate from accumulating on the extrusion mechanism.

[0015] In some embodiments, the extrusion assembly includes an extrusion plate, an extrusion housing, and an extruder, wherein the extrusion orifice plate is disposed between the extrusion plate and the extrusion housing to enclose an extrusion cavity, and the extruder is disposed in the extrusion cavity to extrude the extrudate from the position of the extrusion orifice plate.

[0016] In the above process, the extrusion plate and the extrusion shell are respectively connected to the extrusion orifice plate, and the extruded part is located in the extrusion cavity formed by the three. The material can be crushed and extruded from the extrusion orifice plate. Then, under the drive of the drive structure, the shearing component shears the extruded part, realizing the timely drop of the extruded part, which is conducive to the smoothness of the extruded part extrusion.

[0017] In some embodiments, the extrusion plate includes an extrusion portion and an extension portion. The extrusion portion is provided with a plurality of extrusion holes. The extension portion is disposed at an end of the extrusion portion, and the outer diameter of the extension portion is larger than the outer diameter of the extrusion portion to enclose and form a shearing cavity. The shearing cavity is configured to accommodate a portion of the structure of the shearing assembly.

[0018] In some embodiments, the extrusion assembly further includes a conveyor connected to the extrusion plate for conveying the material to the extrusion chamber.

[0019] In some embodiments, the extrusion assembly further includes a feeder disposed above the conveyor for feeding the material, which is then conveyed by the conveyor.

[0033] Example

[0034] In the pharmaceutical, chemical, materials, and food industries, it is often necessary to granulate materials. Different extrusion equipment using different principles will produce particles with varying degrees of difference. Common extrusion equipment includes screw extrusion, planetary extrusion, and basket extrusion. Screw extrusion is further divided into face extrusion, ball head extrusion, and side extrusion. Face extrusion results in more uniform material stress, while ball head extrusion, due to its spherical discharge surface, causes uneven stress on different parts of the material, leading to variations in extruded material diameter and sometimes incomplete extrusion strips. Side extrusion results in inconsistent material density due to varying degrees of compression during the material's initial extrusion stroke. Screw extrusion produces relatively dense materials, but it also results in high extrusion resistance, low efficiency, and a tendency to generate heat. Planetary and basket extrusion produce relatively loose materials with high extrusion efficiency and low heat generation, but the extrudate is a continuous strip that is difficult to break and fall off promptly, causing it to accumulate at the extrusion site and hindering the smooth extrusion of subsequent materials. This necessitates constant manual removal of the accumulated material, leading to adhesion between extrudates and making them difficult to separate. Furthermore, the extrudate requires granulation after drying, resulting in material loss and increased production costs.

[0035] In view of this, such as Figures 1-3 As shown, in a first aspect, embodiments of this application provide an extrusion apparatus, including: an extrusion mechanism 10, including an extrusion assembly 101 and an extrusion orifice plate 102, the extrusion assembly 101 being configured to crush material to form an extrudate, the extrusion orifice plate 102 being connected to the extrusion assembly 101 for the extrudate to flow out; and a shearing mechanism 20, including a drive structure 201 and a shearing assembly, the drive structure 201 being connected to the shearing assembly, the shearing assembly being disposed outside the extrusion orifice plate 102 for shearing the extrudate.

[0036] For example, the extrusion plate 102 is provided with a plurality of holes, which are configured for the extrusion assembly 101 to extrude the extrudate. The extrusion principle is as follows: raw materials, fillers and other raw and auxiliary materials are uniformly mixed, a wetting agent / binder solution is added to form a soft material, the soft material is then added to the extrusion chamber, and crushed by the extrusion part (i.e. the extruder 1013) that moves closely against the extrusion plate 102. Finally, a dense extrudate of a preset shape is formed through the holes. The preset shape includes, but is not limited to, a cylindrical shape.

[0037] It is understood that the drive structure 201 includes a drive component, a force transmission component, and a rotating wheel. The drive component includes, but is not limited to, a drive motor, and the force transmission component includes, but is not limited to, a transmission belt. The drive component transmits force to the rotating wheel through the force transmission component. The rotating wheel is provided with the shearing assembly, which allows the shearing assembly to rotate at a constant speed relative to the extrusion orifice plate 102, so that the shearing assembly can cut off the extrudate in a timely manner when it is extruded.

[0038] In the above process, the extrusion orifice plate 102 is connected to the extrusion assembly 101, and the drive structure 201 is connected to the shearing assembly. The shearing assembly is located outside the extrusion orifice plate 102, so that after the material enters the interior of the extrusion assembly 101, the extrusion assembly 101 crushes it, and the crushed material forms an extrudate. The extrusion assembly 101 extrudes the extrudate from the extrusion orifice plate 102. Then, the drive structure 201 drives the shearing assembly to rotate, so as to cut the extrudate extruded from the extrusion orifice plate 102 at a uniform speed, which can obtain particles of uniform length and quickly carry them away from the extrusion orifice plate 102, avoiding accumulation and ensuring the smooth extrusion of the extrudate.

[0039] In some embodiments, the shearing assembly includes a connector and a shearing member 205. The connector connects to the shearing member 205, and the shearing member 205 extends to the extrusion orifice plate 102 from the side opposite to the connector. Exemplarily, the connector connects to the rotating wheel, and the connector and the rotating wheel can be fastened together with bolts. Additionally, to facilitate adjustment of the position of the shearing member 205 relative to the extrusion orifice plate 102, the position of the connector relative to the rotating wheel is adjustable, and the position of the shearing member 205 relative to the connector is also adjustable; alternatively, only the position of the shearing member 205 relative to the connector may be adjustable.

[0040] In the above-described process, the shearing member 205 is connected to the connecting member, and the driving structure 201 drives the shearing member 205 to rotate along the outer edge of the extrusion orifice plate 102. Thus, when the extrusion assembly 101 extrudes the extrudate from the extrusion orifice plate 102, the shearing member 205 can cut it off at a uniform speed, thereby obtaining particles of uniform length. This avoids particle accumulation and adhesion to the extrusion assembly 101 or the extrusion orifice plate 102. Furthermore, the particles obtained by shearing do not need to be granulated again to obtain particles of the required size, which can avoid material loss and reduce production costs.

[0041] In some embodiments, the shearing member 205 is spaced apart from the extrusion orifice plate 102. For example, after the shearing member 205 is spaced apart from the extrusion orifice plate 102, by adjusting the extrusion speed and the rotational speed of the shearing member 205, the shearing member 205 can rotate exactly one revolution, shearing the extrudate, and the length of the extrudate after shearing is less than 2 mm, etc.

[0042] In the above process, by spacing the shearing member 205 with the extrusion orifice plate 102, not only can the friction between the shearing member 205 and the extrusion orifice plate 102 be avoided to obtain particles of the required size, but the shearing member 205 can also effectively shear the extrudate under the action of the driving structure 201, avoiding the accumulation of the extrudate and ensuring the smoothness of the extrudate extrusion.

[0043] like Figure 3 As shown, the connector includes a first connector 202 and a second connector 203. The first connector 202 has a mounting groove 206 along its length. One end of the second connector 203 is connected to the mounting groove 206, and the other end is detachably connected to the shearing member 205. The second connector 203 includes a first part and a second part, which are integral structures. The first part is a threaded section, which is disposed in the mounting groove 206 and locked by a nut. The outer diameter of the second part is larger than the width of the mounting groove 206, so that the second part can abut against the mounting groove 206 and be easily fastened to the first connector 202 by a nut. At the same time, the length of the mounting groove 206 can be set to be larger than the outer diameter of the second connector 203, so that the position of the second connector 203 relative to the first connector 202 can be easily adjusted.

[0044] In the above implementation process, the second connector 203 is connected to the mounting groove 206 of the first connector 202, so that the second connector 203 can be adjusted relative to the first connector 202 through the mounting groove 206, thereby adjusting the position of the shearing member 205 relative to the extrusion plate 102, improving the shearing effect. At the same time, the shearing member 205 is detached and connected to the second connector 203, which is conducive to the replacement and maintenance of the shearing member 205 and improves efficiency.

[0045] In some embodiments, the second connector 203 is provided with an inclined portion 204 distributed along a preset angle. The inclined portion 204 is provided with a snap-fit ​​cavity, and a portion of the shearing member 205 is disposed in the snap-fit ​​cavity. The preset angle can be set to 0-90° or 90°-180°, for example, 120°, 130°, 135°, etc. By installing the shearing member 205 in the snap-fit ​​cavity, the shearing member 205 is inclined, which is beneficial for the shearing of the extrudate by the shearing member 205 and avoids the accumulation of extrudate.

[0046] In some embodiments, a plurality of shearing components are configured, and the plurality of shearing components are distributed at intervals along the periphery of the extrusion assembly 101. For example, four shearing components are configured, and the four shearing components are equally spaced on the extrusion assembly 101. This enables effective shearing of the extrudate around the periphery of the extrusion orifice plate 102, avoiding the accumulation of the extrudate on the extrusion mechanism 10.

[0047] In some embodiments, the extrusion assembly 101 includes an extrusion plate 1011, an extrusion housing 1012, and an extruder 1013. The extrusion orifice plate 102 is disposed between the extrusion plate 1011 and the extrusion housing 1012 to enclose and form an extrusion cavity. The extruder 1013 includes, but is not limited to, extrusion rollers. A plurality of extruders 1013 are disposed in the extrusion cavity to extrude the extrudate from the position of the extrusion orifice plate 102.

[0048] In the above process, the extrusion plate 1011 and the extrusion shell 1012 are respectively connected to the extrusion orifice plate 102, and the extruder 1013 is located in the extrusion cavity formed by the three. It can crush the material and extrude it from the extrusion orifice plate 102. Then, under the drive of the drive structure 201, the shearing component shears the extrudate, realizing the timely drop of the extrudate, which is conducive to the smoothness of the extrudate extrusion.

[0049] like Figure 2 As shown, the extrusion plate 102 includes an extrusion section and an extension section. The extrusion section is provided with a plurality of extrusion holes. The extension section is disposed at the end of the extrusion section, and the outer diameter of the extension section is larger than the outer diameter of the extrusion section, so as to enclose and form a shearing cavity. The shearing cavity is configured to accommodate a portion of the shearing assembly.

[0050] In some embodiments, the extrusion assembly 101 further includes a conveyor, which includes, but is not limited to, a screw, and is connected to the extrusion plate 1011 for conveying the material to the extrusion chamber.

[0051] In some embodiments, the extrusion assembly 101 further includes a feeder, which includes, but is not limited to, a feed hopper, and is disposed above the conveyor for feeding the material and conveying it by the conveyor.
