DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0020] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0021] In addition, the descriptions of "first", "second", etc. in this application are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0022] The embodiments of the present application provide a paste collecting machine and a control method, thereby solving the technical problem in the prior art that the stirring speed and heating power of the paste collecting equipment still rely on manual adjustment and have poor accuracy.

[0023] The technical solution in the embodiments of the present application is to solve the above technical problems, and the overall idea is as follows: like Figure 1-Figure 3 As shown, the present invention discloses a paste collecting machine, which includes a pot body 10, a stirring motor 30, a stirring blade 31, a torque sensor 32 and a heating component 50. The pot body 10 is made of red copper, and the stirring blade 31 is made of winter bamboo. The pot body 10 is mounted on a bracket 20. The pot body 10 is spherical, which reduces the dead angle of stirring and promotes the flow of liquid medicine; the stirring motor 30 is installed on the bracket 20 above the pot body 10, and the stirring blade 31 is installed on the output shaft of the stirring motor 30 through the stirring shaft 40. The stirring motor 30 is a servo motor with a reducer; the torsion bar of the torque sensor 32 is installed between the stirring shaft 40 and the output shaft of the stirring motor 30 through a rigid coupling, and the heating component 50 is installed on the bracket 20 below the pot body 10. A roller can be provided at the lower end of the bracket 20 for easy movement.

[0024] By setting a torque sensor 32 between the stirring shaft 40 and the output shaft of the stirring motor 30, the resistance change of the medicinal liquid during the stirring process can be monitored in real time and continuously, that is, the dynamic change of the viscosity of the medicinal liquid can be reflected. Based on the change of the torque value, the speed of the stirring motor 30 and the heating power of the heating component 50 can be automatically adjusted to achieve dynamic matching of the speed and heat input, effectively overcoming the subjectivity and instability brought about by traditional empirical judgments such as "hanging flags" and "dripping water into beads", and significantly improving the consistency and reliability of product quality.

[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0026] Preferably, Figure 4 、 Figure 5 As shown, the stirring shaft 40 includes: The sleeve 41 is made of stainless steel and has good torsional strength and corrosion resistance. The sleeve 41 is installed on the torsion bar of the torque sensor 32. Specifically, the sleeve 41 is a hollow circular tube structure, one end of which is rigidly connected to the torsion bar of the torque sensor 32 through a coupling, and the other end is open to accommodate the slide rod 43. The side of the sleeve 41 is provided with an elongated hole 42 along its axial direction. A sliding rod 43 is made of a solid stainless steel rod. The sliding rod 43 is slidably disposed in the sleeve 41 . A locking screw 44 is provided on the sliding rod 43 , and the locking screw 44 passes through the elongated hole 42 . The blade rack 33 is made of stainless steel. There are multiple blade racks 33 evenly distributed around the slide rod 43 . The blade rack 33 is installed at the end of the slide rod 43 , and the stirring blade 31 is installed on the blade rack 33 .

[0027] By adjusting the relative position of the slide rod 43 and the sleeve 41 and locking it with the locking screw 44, the depth of the stirring blade 31 can be adjusted. Combined with the spiral scraping structure, it can effectively break the liquid surface conjunctiva, promote the circulation of the upper and lower layers of medicine, prevent local overheating or concentration gradient, significantly improve the uniformity of mass transfer and heat transfer, and shorten the concentration time; and by adjusting the extended length of the slide rod 43, the same device can adapt to pots 10 of different volumes or medicine volumes of different prescriptions, thereby improving equipment utilization.

[0028] Further, the stirring shaft 40 further comprises a butt joint shaft 45, one end of the butt joint shaft 45 is fixedly connected with the torsion bar of the torque sensor 32 through a shaft coupling, the butt joint shaft 45 is a polygonal solid shaft, in the embodiment, the butt joint shaft 45 is quadrangular, the other end of the butt joint shaft 45 is inserted into the sleeve 41, the butt joint shaft 45 can slide in the sleeve 41, the butt joint shaft 45 is clamped with the end of the sleeve 41, the corresponding end of the butt joint shaft 45 and the sleeve 41 is provided with a clamping groove and a flange structure, so that the butt joint shaft 45 and the sleeve 41 can be limited after sliding to the end position, the spring 46 is arranged on the butt joint shaft 45, one end of the spring 46 is fixedly connected with the butt joint shaft 45, the other end of the spring 46 is in contact with the end of the sleeve 41.

[0029] When the paste is collected, the sleeve 41 is always subjected to the elastic force of the spring 46, so that the stirring blade 31 at the end of the stirring shaft 40 can always be close to the inner wall of the kettle 10, when the liquid medicine is rapidly thickened or suddenly blocked in the late stage of paste collection, the stirring resistance sharply rises, the spring 46 is compressed, the impact energy is absorbed, the torque sensor 32 is prevented from being damaged due to instantaneous overload, the torque transmission is maintained, the change of the liquid medicine volume, the expansion of the foam or the slight mechanical deformation is adapted, the stress concentration or the jamming phenomenon caused by the rigid structure is avoided, and the impact resistance and the service life of the system are significantly improved.

[0030] Meanwhile, the spring 46 buffering mechanism can filter out the instantaneous pulsating torque interference caused by the liquid medicine fluctuation, bubble burst or local adhesion, so that the torque signal collected by the sensor is more stable, the overall viscosity trend of the liquid medicine is truly reflected, and the accuracy of the end point judgment is improved.

[0031] Preferably, as Figure 2 、 Figure 6 Figure 7As shown, the heating assembly 50 includes a spherical heating plate 51 and a heating tube 52. The spherical heating plate 51 is mounted on the bracket 20 through a high-temperature resistant shock-absorbing bracket 20 or an elastic support foot. The spherical heating plate 51 is located below the pot body 10. The pot body 10 is arranged in the recessed space of the spherical heating plate 51. The spherical heating plate 51 is in the shape of a concave spherical cap or parabola as a whole. The recessed space matches the curvature of the bottom of the pot body 10, so that a large area of ​​the bottom of the pot body 10 is attached to the surface of the spherical heating plate 51, thereby improving the thermal contact area and heat transfer efficiency. Specifically, the concave portion of the spherical heating plate 51 is The sinking depth is 1 / 6-1 / 4 of the diameter of the pot body 10, ensuring that the pot body 10 is stably embedded to prevent displacement or overturning. The central axis of the spherical heating plate 51 is aligned with the center of the pot body 10 to ensure uniform heating, prevent local coking or component destruction, and ensure the stability of the ointment quality; the heating tube 52 is embedded on the inner side of the spherical heating plate 51, and the heating tube 52 is an infrared heating tube 52; the outer side of the spherical heating plate 51 is provided with a thermal insulation reflective layer 53, which is a tin foil thermal insulation reflective plate. The thermal insulation reflective layer 53 feeds radiant heat back to the pot body 10, saving heat energy and lowering operating costs.

[0032] More preferably, Figure 6 As shown, a paste outlet 11 is provided at the bottom of the pot body 10, and a plug 12 is operably inserted into the paste outlet 11. The plug 12 is made of food-grade stainless steel, and its outer wall cooperating with the paste outlet 11 is provided with a high-temperature resistant silicone sealing ring. The plug 12 can also be increased with a handle 13 to facilitate manual operation to discharge the ointment. When the handle 13 is provided, the plug 12 is inserted into the paste outlet 11, and the end face of the plug 12 is tangent to the inner wall of the pot body 10, so that the stirring blade 31 will not contact the plug 12, and the stirring blade 31 has a spacing in the radial direction of the pot body 10, so that the handle 13 can be accommodated in the space between the stirring blades 31; a through hole 54 is opened on the spherical heating plate 51 corresponding to the paste outlet 11 to ensure that the ointment can be directly discharged to the outside of the pot body 10, realizing aseptic and rapid transfer.

[0033] Furthermore, the spherical heating plate 51 is hollowed out, and the heating tubes 52 are arranged in multiple layers around the bottom of the spherical heating plate 51 and spaced upward. The hollowed-out position of the spherical heating plate 51 is located between the heating tubes 52, which reduces the weight of the equipment and prevents the bracket 20 from overheating.

[0034] Preferably, Figure 2 、 Figure 3As shown, a shell 21 is fixedly provided on the bracket 20. The shell 21 is an integral box-shaped structure, covering the pot body 10 and the stirring motor 30. The shell 21 is made of cold-rolled steel plate, and flame-retardant heat-insulating cotton is installed on the inside. The shell 21 is provided with an air collecting groove 22 corresponding to the top of the pot body 10, and a fan 23 is fixedly provided in the air collecting groove 22. An air outlet 24 is provided on the side of the shell 21 corresponding to the exhaust direction of the fan 23.

[0035] During the process of collecting the ointment, the liquid medicine is heated to generate a large amount of water vapor and volatile components, which are forcibly sucked out by the fan 23. The steam is collected and concentrated through the air duct 22 and discharged from the air outlet 24 in a targeted manner, which significantly reduces the diffusion of steam in the operating area, avoids humidity in the workshop and blurred vision, and improves work safety and comfort.

[0036] Preferably, Figure 1 As shown, the paste collecting machine also includes a paste collecting mechanism 60, which includes a container 61, a turnover box 62 and a trolley 63. The trolley 63 can be operably pushed under the pot body 10, the turnover box 62 is placed on the trolley 63, and the container 61 is placed in the turnover box 62.

[0037] After the ointment is collected, the trolley 63 is pushed to the bottom of the pot body 10, the container 61 is aligned with the ointment outlet 11, and then the plug 12 is pulled out. The ointment flows into the container 61 through the ointment outlet 11. After the ointment is discharged, the trolley 63 is moved out to avoid the risk of burns caused by splashing of high-temperature ointment during manual termination; the operator can operate the plug 12 at a safe distance, which greatly improves the safety of the operation, shortens the equipment occupancy time, and avoids pollution to the workshop.

[0038] The present application also provides a control method for a paste collecting machine, which is applied to the paste collecting machine described in any one of the above technical solutions, and the control method includes: controlling the stirring speed of the stirring motor according to the signal of the torque sensor; , controlling the heating power of the heating device according to the signal of the torque sensor; , Among them, the speed is R, the heating power is P, the measured torque value is T, and the set maximum torque value is , set the minimum torque value to , is the coefficient.

[0039] The torque sensor continuously detects the resistance torque T on the stirring shaft, which directly reflects the change in the viscosity of the liquid. The higher the viscosity, the greater the stirring resistance and the greater the resistance torque T.

[0040] Dynamic adjustment of stirring speed: at the initial stage of cream collection, the liquid is thin, T is small, and the control system maintains high speed, R≈R max , to promote the rapid flow and uniform heating of the liquid; as concentration proceeds, T gradually rises, and the controller automatically reduces the stirring motor speed according to the preset algorithm to prevent motor stall, increased energy consumption, or structural damage due to excessive viscosity; in the later high-viscosity state, low-speed operation is adopted to ensure that the cream is fully mixed without damaging its structure.

[0041] Synergistic adjustment of heating power: at the initial stage, T is small, and the system outputs high heating power, P≈P max , to speed up water evaporation; as T rises, indicating that the liquid is close to the end of concentration, the system gradually reduces the heating power and switches to slow simmering mode to prevent local high temperature from causing decomposition or coking of active ingredients; intelligent thermal management is achieved to “simmer slower as the cream thickens”.

[0042] When T rises to T max , and remains stable for a set time, such as 5 minutes, the system determines that it is in the “flag hanging” or “bead dripping” state; it automatically issues an audible and visual alarm to prompt the operator that the cream collection is complete, or to automatically turn off the heating and start the cream discharge program.

[0043] Through the cream collection machine and control method provided by the present application, the speed and heating power are automatically adjusted according to the actual viscosity state of the liquid, achieving self-adaptive control of “slow stirring and low temperature for thick cream, fast stirring and high temperature for thin cream”, avoiding human adjustment lag or misjudgment, and improving energy utilization efficiency; completely getting rid of the traditional subjective methods of relying on manual experience to judge “flag hanging” and “thread pulling”, using objective and quantifiable torque data as the control basis to ensure consistency of each batch of process and improve product quality stability.

[0044] Automatic speed reduction in the high-viscosity stage effectively protects the motor, speed reducer, and torque sensor; simultaneous reduction of heating power eliminates problems such as local overheating, coking, and scaling, ensuring the color, odor, and efficacy of the cream; high-power heating and high-speed stirring at the initial stage significantly speeds up the water evaporation rate in the early stage; no frequent manual intervention is required throughout the process, reducing downtime.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present application.

[0046] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
