Description

Technical Field

[0001] The utility model relates to the technical field of extrusion equipment, in particular to an ointment quantitative extrusion device. Background Art

[0002] In the production process of ointment, a key step is to accurately quantitatively fill the ointment. This step is crucial because it ensures that each portion of the ointment meets the specified dosage standards, thereby guaranteeing the efficacy and safety of the medicine. To achieve this goal, professional ointment quantitative extrusion equipment is required. This equipment can accurately control the extrusion amount of the ointment. Whether it is small-scale production or large-scale batch production, it can ensure that the dosage of each portion of the ointment is accurate. Through the quantitative extrusion operation of this equipment, not only can the production efficiency be improved and human error be reduced, but also the stability and consistency of the ointment during use can be ensured, providing a more reliable treatment guarantee for patients.

[0003] In the patent "A canned solder paste filling machine" (publication number CN212024741U, hereinafter referred to as the prior art 1), an extrusion device for ointment is disclosed. The prior art 1 is composed of a pressure-bearing platform and an extrusion platform. This platform can stably support the weight of the entire filling machine. The extrusion platform is responsible for effectively extruding the solder paste so that it can smoothly flow into the filling syringe. The filling machine also has a protrusion that can penetrate into the interior of the filling syringe. The function of this part is to facilitate the accurate feeding of the solder paste into the syringe interior and improve the filling accuracy. The filling machine is also equipped with a lead screw device. This device can achieve precise control of the solder paste through cooperation with the driving motor, enabling it to be filled at a set speed.

[0004] When the prior art 1 is in use, the paste in the can is extruded through the extrusion platform and loaded into the interior of the syringe through the diversion fixture. However, the prior art 1 does not have a quantitative control extrusion setting, resulting in the inability to effectively control the amount of the extruded paste. So that the amount of the extruded paste is different each time. Summary of the Utility Model

[0033] Embodiment 1

[0034] Please refer to Figure 1 , the embodiments of the present utility model provide an ointment quantitative extrusion device for extruding the produced soft cream, including imiquimod cream, butenafine hydrochloride cream, terbinafine hydrochloride cream, zinc oxide sulfur ointment, etc., for quantitative extrusion and then packaging.

[0035] An ointment quantitative extrusion device provided by an embodiment of the present utility model includes a base 100, and the base 100 is used to install various components, including an extrusion mechanism. Each component of the extrusion mechanism is fixedly arranged on the base 100. The base 100 is also used to move and install the whole device and place it at a position where extrusion processing needs to be carried out. The base 100 includes a side plate 110 and a first mounting plate 120, and the first mounting plate 120 is vertically assembled with the side plate 110 and extends towards one end away from the side plate 110.

[0036] Please refer to Figure 2 , the base 100 includes a side plate 110 and a first mounting plate 120; the first mounting plate 120 is vertically assembled with the side plate 110 and extends towards one end away from the side plate 110. A through hole is provided on the first mounting plate 120; a storage cylinder 130 is detachably installed in the through hole. The through hole on the first mounting plate 120 is used to fix and hang the storage cylinder 130. And at least two mounting plates perpendicular to the side plate 110 are provided on the base 100, and this first mounting plate 120 is one of them. The main function of these mounting plates is to provide accurate mounting positions for various components, ensure their correct placement and fixation in the device, so as to ensure the normal operation and stability of the device.

[0037] An extrusion mechanism and a gland 150 are provided in the storage cylinder 130; the storage cylinder 130 is a transparent cylinder, and scale lines are provided on the outer edge of the storage cylinder 130.

[0038] Please refer to Figure 3 , the storage cylinder 130 provided by the present utility model is provided with an extrusion mechanism and a gland 150. Such a configuration enables the ointment to be extruded while being stored, greatly improving the use efficiency. The storage cylinder 130 is made of a transparent material, which not only makes the storage state of the material clear at a glance and is convenient for users to observe at any time, but also makes the whole storage cylinder 130 appear cleaner and more beautiful. In addition, in order to facilitate users to more accurately control the extrusion amount of the material, scale lines are provided on the outer edge of the storage cylinder 130, and users can read the values on the scale lines according to needs, so as to accurately control the extrusion amount and ensure the accuracy of production and processing. It is also possible to perform quantification according to the rotation number of the driven wheel 240 in this embodiment.

[0039] The interior of the storage cylinder 130 is provided as a cavity for storing ointment; the height of the pressing cover 150 is kept consistent with the height of the ointment. The interior of the storage cylinder 130 is designed as a hollow structure specifically for storing the substance of ointment. Meanwhile, the structural height of the pressing cover 150 matches the height of the ointment filled in the storage cylinder 130, ensuring that the two maintain the same horizontal line in the vertical direction. The purpose of this is that during the use of the ointment, the remaining amount and the extruded amount of the ointment can be directly judged by the height of the pressing cover 150, facilitating the user to monitor the usage situation of the ointment. In addition, this setting also helps to thoroughly clean the storage cylinder 130 after the ointment is used up, because the pressing cover 150 is flush with the surface of the ointment, avoiding the residue of the ointment on the cylinder wall and reducing the difficulty of cleaning.

[0040] Please refer to Figure 3 , on the inner surface of the storage cylinder 130, there are provided protrusions 320, and on the pressing cover 150, there are grooves adapted to the protrusions 320. The pressing block is engaged with the protrusions 320 of the storage cylinder 130 through the grooves, and the pressing block moves along the path of the protrusions 320. On the inner surface of the storage cylinder 130, raised protrusions 320 are designed. The function of these protrusions 320 is to increase the friction of the material inside the storage cylinder 130 when the pressing cover 150 moves, so as to ensure that the movement of the pressing cover 150 is consistent with the ointment during extrusion and can move stably without deviation. At the same time, these protrusions 320 can also improve the distribution of the material to a certain extent, making it more uniform. In addition, the top of the pressing cover 150 is designed with grooves matching these protrusions 320, and the shapes and positions of these grooves correspond precisely to the protrusions 320 to ensure that the pressing block can be engaged with the protrusions 320.

[0041] When it is necessary to compress or extrude the material in the storage cylinder 130, the pressing block will move along the path of the groove, which can ensure that the contact between the pressing block and the protrusions 320 is always uniform, thus realizing the effective compaction and extrusion of the material. During this process, the pressing block will closely fit on the protrusions 320, and through the applied pressure, the material will form a more compact accumulation inside the storage cylinder 130.

[0042] Please refer to Figure 3, a discharge port 330 is provided at the bottom of the storage cylinder 130; the ointment is extruded out of the storage cylinder 130 by the operation of the extrusion mechanism and discharged from the discharge port 330. The setting of the discharge port 330 facilitates the smooth discharge of the material. Under the action of the extrusion mechanism, the ointment in the storage cylinder 130 is effectively extruded and discharged through the discharge port 330. This process realizes the continuous output of the ointment and ensures the extrusion efficiency. At the same time, the setting of the discharge port 330 should consider the fluidity of the material and the working principle of the extrusion mechanism to ensure that the ointment can be discharged evenly and stably. Through this setting, the ointment can be quantitatively extruded into the ointment packaging box 700 to complete the packaging of the ointment.

[0043] Preferably, the extrusion mechanism includes a motor 210, a rotating shaft 220, a driving wheel 230 and a driven wheel 240; the motor 210 is arranged on the first mounting plate 120; the driving wheel 230 is fixedly connected to the output shaft of the motor 210. The rotating shaft 220 extends from one end of the storage cylinder 130 into the interior of the storage cylinder 130. The driving wheel 230 and the driven wheel 240 are arranged on the same horizontal plane and are meshed and driven with each other; both ends of the rotating shaft 220 are respectively provided with an auger 250 and a driven wheel 240; both the auger 250 and the driven wheel 240 are fixedly connected to the rotating shaft 220. An axial hole is provided on the gland 150, and the rotating shaft 220 passes through the axial hole.

[0044] Preferably, the auger 250 includes a rotating cylinder 251 and a thread; the rotating cylinder 251 is fixedly assembled with the rotating shaft 220; the thread is arranged on the rotating cylinder 251; the major diameter of the thread is smaller than the inner diameter of the storage cylinder 130; an ointment extrusion path is formed between the gap of the thread and the inner wall of the storage cylinder 130.

[0045] Please refer to Figure 3, a storage barrel 130 is provided in the through hole on the first mounting plate 120; the rotating shaft 220 extends into the interior of the storage barrel 130; the auger 250 is mounted on the rotating shaft 220 within the storage barrel 130 and extends from one end of the rotating shaft 220 to the other end; the storage barrel 130 is provided with a discharge port 330 at the bottom. The first mounting plate 120 is prepared with through holes for fixing, and the storage barrel 130 is arranged within the through holes. This rotating shaft 220 extends from the first mounting plate 120 into the interior of the storage barrel 130. Inside the storage barrel 130, there is an auger 250, which is integrally in a spiral structure and is tightly mounted on the rotating shaft 220. To facilitate the extrusion of the material, the storage barrel 130 is designed with a discharge port 330 at the bottom. When the material to be extruded is placed into the storage barrel 130, through the rotational movement of the auger 250, the material is effectively extruded through the discharge port 330. The storage barrel 130 and the first mounting plate 120 are detachably assembled. When all the ointment is extruded, it is disassembled or replaced so that the extrusion operation of the ointment can be carried out again. When the ointment is extruded, the gland 150 descends simultaneously as the amount of the ointment decreases.

[0046] When performing the extrusion operation, by starting the motor 210, the rotating shaft 220 is driven, causing the auger 250 to work and completing the extrusion operation of the ointment. When extruding like this, the amount of the ointment used is checked and controlled according to the part where the scale on the storage barrel 130 aligns with the bottom of the gland 150, achieving the effect of quantitative extrusion. Before the extruded ointment is installed in the extrusion mechanism, it is placed in the storage barrel 130 in advance. The top of the storage barrel 130 is open, and its opening is used to place the extrusion components, including the rotating shaft 220 and the auger 250. Generally, the auger 250 is often placed inside the storage barrel 130, and the rotating shaft 220 is fixedly connected to the auger 250. Open the top of the storage barrel 130 and put the ointment in; at this time, the rotating shaft 220 is not yet connected to the driving components. Sleeve the gland 150 on the rotating shaft 220, and then make a driving connection between the driving components and the rotating shaft 220. At this time, the loading is completed, and the quantitative extrusion operation can be carried out. When extruding, the gland 220 is in contact with the ointment. As the height of the ointment decreases, the gland 220 descends. When reloading is required, take out the driving components and the gland for cleaning or directly add water for spiral stirring and cleaning. After cleaning, remove the driving components and the gland and then load the material.

[0047] Furthermore, an internal cavity is provided inside the storage cylinder 130, which is the storage chamber 310; the storage chamber 310 includes a storage section 311 and a discharging section 312. The inside of the storage cylinder 130 is provided as a cavity to facilitate the storage of the ointment. And this storage chamber 310 is further subdivided into two parts: the storage section 311 and the discharging section 312. The main function of the storage section 311 is to store the material to ensure that the material can be used at any time when needed; while the discharging section 312 is responsible for effectively extruding the material stored in the storage section 311 for the next operation or processing. This makes the storage and output of the material smoother and more convenient.

[0048] Furthermore, the discharging section 312 is arranged in a conical shape, and the discharging port 330 is provided at the bottom of the discharging section 312. The discharging section 312 is arranged in a conical structure, which can effectively increase the fluidity of the material and reduce the resistance during discharging. And the discharging port 330 is placed at the bottom position of the conical discharging section 312, which can ensure that the material can flow more smoothly during the discharging process and reduce the problem of unsmooth discharging caused by material blockage. This not only improves the discharging efficiency of the equipment but also reduces the maintenance difficulty of the equipment, thus improving the overall service life of the equipment.

[0049] Please refer to Figure 3 , furthermore, the discharging port 330 is also connected with an end cap, and the end cap can close or open the discharging port 330. An auxiliary discharging pipe 410 is provided at the discharging port 330, and the auxiliary discharging pipe 410 communicates the storage chamber 310 with the outside. This end cap can effectively seal the discharging port 330 to ensure the integrity and hygiene of the material during transportation and storage. The design of the end cap needs to consider the function of being easy to open and close to facilitate the loading and unloading operation of the material by the operator. Generally, a threaded connection can be used to seal and close the storage chamber 310. To improve the efficiency and convenience of material transportation, an auxiliary discharging pipe 410 is also equipped at the discharging port 330. This auxiliary discharging pipe 410 plays a bridging role. It connects the storage chamber 310 with the external environment to ensure that the ointment can flow out smoothly and continuously. The design of the auxiliary discharging pipe 410 should consider its material and size to meet the transportation requirements of different materials, and at the same time be easy to clean and maintain to ensure the long-term stable operation of the equipment.

[0050] Furthermore, please refer to Figure 3, the auger 250 includes a rotating cylinder 251 and threads; the rotating cylinder 251 is fixedly assembled with the rotating shaft 220; the threads are provided on the rotating cylinder 251. The rotating cylinder 251 is a cylindrical member, and its function is to provide a rotating surface so that materials can be stirred or conveyed thereon. The threads are spiral protrusions provided along the outer wall of the rotating cylinder 251, and their function is to push the materials forward through the inclined surface of the spiral when the rotating cylinder 251 rotates. The rotating cylinder 251 and the rotating shaft 220 are fixedly assembled to ensure that the rotating cylinder 251 can rotate around the rotating shaft 220. During installation, the rotating cylinder 251 and the rotating shaft 220 are fixed together to ensure that the rotating cylinder 251 can rotate smoothly. When cleaning is required, the rotating cylinder 251 can be removed from the rotating shaft 220 to thoroughly clean the rotating cylinder 251, thereby ensuring the cleanliness and hygiene of the auger 250 device. This design makes the maintenance and cleaning of the auger 250 device very convenient, improving the use efficiency and service life of the auger 250 device.

[0051] Preferably, the major diameter of the threads is smaller than the inner diameter of the storage cylinder 130; an ointment extrusion path is formed between the gaps of the threads and the inner wall of the storage cylinder 130. The major diameter of this thread device is smaller than the inner diameter of the storage cylinder 130, so that a gap is formed between the threads and the inner wall of the storage cylinder 130. It is through this gap that the ointment is extruded.

[0052] Specifically, an ointment extrusion path is formed between the gaps of the threads and the inner wall of the storage cylinder 130. This path is determined by the dimensional difference between the major diameter of the threads and the inner diameter of the storage cylinder 130. Since the major diameter of the threads is slightly smaller than the inner diameter of the storage cylinder 130, a channel is formed between the threads and the inner wall of the storage cylinder 130. This channel can convey the ointment, so that when the auger 250 rotates, the ointment can receive a downward pressing force and be extruded from the storage cylinder 130.

[0053] In addition, due to the spiral shape of the threads, when the threads rotate in the storage cylinder 130, the ointment will be pushed along the spiral path of the threads, thus realizing the continuous extrusion of the ointment. The utility model can effectively extrude the ointment from the storage cylinder 130, and is not only applicable to the packaging and filling operations of ointment, but also applicable to various occasions where ointment needs to be used.

[0054] Embodiment 2

[0055] Please refer to Figure 4 , the embodiment of the utility model provides an ointment quantitative extrusion device, and the extrusion mechanism includes a cylinder 510; the piston rod 511 of the cylinder 510 is fixedly connected with the gland 150.

[0056] The main function of the extrusion mechanism is to extrude materials under pressure during the production or use of ointments. In this mechanism, the air cylinder 510 is a device that can convert the kinetic energy of compressed air into linear mechanical motion. Its working principle is to drive the piston rod 511 to move linearly through the expansion of compressed air. In this extrusion mechanism, the piston rod 511 of the air cylinder 510 is fixedly connected to the gland 150. This connection method enables the movement of the piston rod 511 to be directly transmitted to the gland 150, thereby realizing the extrusion of the ointment. There are many ways of fixed connection, such as screw connection, key connection, pin connection, etc.

[0057] In this embodiment, the ointment is loaded through the top opening of the storage barrel 130, and then the extrusion mechanism is installed. To drive the extrusion mechanism to complete the extrusion operation, when loading is required, the extrusion mechanism is disassembled for cleaning. After cleaning the storage barrel 130, the ointment is loaded through the top opening of the storage barrel 130.

[0058] Preferably, the base 100 further includes a second mounting plate 140, and the second mounting plate 140 is arranged in parallel with the first mounting plate 120 at a preset interval distance; the air cylinder 510 is arranged on the second mounting plate 140. Specifically, the second mounting plate 140 is located at the top of the first mounting plate 120, and its main function is to provide space for installing the air cylinder 510. Such a design not only optimizes the structure of the base 100, but also is beneficial to the stability and operation efficiency of the air cylinder 510.

[0059] Preferably, the discharge port 330 is provided with an auxiliary discharge pipe 410, and the auxiliary discharge pipe 410 connects the storage cavity 310 with the outside. The discharge port 330 is equipped with an auxiliary discharge pipe 410, and the function of this auxiliary discharge pipe 410 is to connect the storage cavity 310 with the external environment. In this way, the discharge of materials will be smoother, greatly improving the working efficiency of the equipment.

[0060] Please refer to Figure 4, the inner cavity of the storage cylinder 130 is set as the storage chamber 310; the storage chamber 310 includes a storage section 311 and a discharge section 312. The discharge section 312 is conically arranged, and the discharge port 330 is provided at the bottom of the discharge section 312. The inner cavity of the storage cylinder 130 is set as the storage chamber 310, and this storage chamber 310 has two parts: the storage section 311 and the discharge section 312. Such a setting enables the material to be better stabilized inside the storage cylinder 130, avoiding the shaking and leakage of the ointment. In the setting of the discharge section 312, it is set in a conical shape, and the purpose of this is to make the discharge smoother, reducing the resistance of the material during the discharge process, so that the ointment can smoothly enter the downstream ointment packaging box 700. And the discharge port 330 is provided at the bottom of the discharge section 312. The advantage of this design is that it can ensure the discharge efficiency while effectively preventing the overflow of the material during the discharge process, and can also make the ointment directly enter the connected ointment packaging box 700 for filling.

[0061] Embodiment 3

[0062] Please refer to Figure 5 , the embodiment of the present utility model provides an ointment quantitative extrusion device and a conveying mechanism 600. During the operation of the ointment quantitative extrusion device, relying on the continuous operation of the conveying mechanism 600, a series of ointment packaging boxes 700 are continuously transported for filling and loading the ointment. The tops of these ointment packaging boxes 700 are set as sealed structures to ensure that the contents will not leak, while the bottoms are provided with openings for the introduction of the ointment. During the filling process, the ointment packaging boxes 700 are firmly installed on the brackets of the conveying mechanism 600 with the tops facing downwards, so as to achieve stable transportation.

[0063] As the ointment packaging boxes 700 move smoothly on the conveying mechanism 600, the openings at the bottoms of the ointment packaging boxes 700 face upwards, facilitating the extrusion of the ointment into the interiors of the ointment packaging boxes 700. Once the ointment is successfully extruded into the ointment packaging boxes 700 quantitatively, the conveying mechanism 600 will continue to work, transport the ointment packaging boxes 700 filled with the ointment out, and then seal the bottoms of the ointment packaging boxes 700 to ensure that the ointment will not leak due to external factors. This series of operation processes realizes the quantitative filling and conveying operations of the ointment, improves the work efficiency and accuracy, and at the same time reduces the risk of manual operation, which is an ideal choice for the filling of medical ointments.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
