Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical processing equipment, and more specifically, to a grinding mill pump head mechanism and a grinding mill. Background Technology

[0002] Currently, most pharmaceutical grinding mills on the market have significant shortcomings in temperature detection. Specifically, the grinding mill's cavity lacks a temperature detection structure, making it impossible to obtain real-time temperature data within the grinding mill cavity. In terms of overall equipment construction, the grinding mill pump head is a completely enclosed structure, with no space reserved for installing temperature detection devices, and the equipment itself lacks any wiring or interfaces related to temperature detection.

[0003] As a result, it is impossible to obtain the temperature changes inside the grinding chamber of the grinder during the grinding process, and it is impossible to make adaptive adjustments to the grinding strategy based on temperature changes during the grinding process. There is a possibility that abnormal temperature may lead to drug quality problems, making it difficult to guarantee the quality and stability of the drug. Utility Model Content

[0004] The purpose of this invention includes, for example, providing a grinding mill pump head mechanism and a grinding mill, which can acquire the grinding mill chamber temperature in real time and reduce the probability of drug quality problems caused by high temperature.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0032] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0033] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0034] In existing technologies, during the operation of the pump head mechanism of a pharmaceutical grinder, the grinding head 300 rotates relative to the housing 100, using impact force to pulverize the pharmaceuticals and reduce their particle size. During this process, frictional heat is generated, meaning the temperature inside the grinder cavity 001 rises. Because the existing pump head mechanism lacks a temperature probe, it is impossible to monitor the temperature inside the grinder cavity 001 in real time during grinding, and therefore, the high temperature can negatively impact pharmaceutical quality.

[0035] In view of this, the designer provides a grinding mill pump head mechanism and a grinding mill. By acquiring the temperature inside the grinding mill chamber 001 in real time, the grinding strategy can be adjusted in a timely manner when the temperature is abnormal, thereby reducing the impact of temperature rise on drug quality and improving the reliability and stability of drug quality.

[0036] Please refer to Figures 1-4 This embodiment provides a grinding machine pump head mechanism, including a housing 100, an end cap 200, a grinding head 300, and a temperature probe 400, wherein:

[0037] End cap 200 is installed on housing 100, and the two cooperate to define a sealed chamber; grinding head 300 is installed inside housing 100, and grinding head 300 and housing 100 are rotatably engaged, and there is an annular gap between the outer peripheral surface of grinding head 300 and the inner peripheral surface of housing 100 to form grinding chamber 001; temperature probe 400 is fixed to end cap 200, and the body 410 of temperature probe 400 extends into grinding chamber 001.

[0038] As described above, the working principle of the grinding machine pump head mechanism provided in this embodiment is as follows:

[0039] The medicine is loaded into the grinding chamber 001, and the motor connected to the grinding head 300 is started. The motor drives the grinding head 300 to rotate. During the rotation of the grinding head 300, the medicine moves together within the grinding chamber 001. The medicine is ground and pulverized by the cooperation of the grinding head 300 and the housing 100, reducing the particle size until the set particle size requirement is met, at which point grinding stops. During the grinding process, a temperature probe 400 is installed on the end cap 200, and the body 410 of the temperature probe 400 extends into the grinding chamber 001. The temperature inside the grinding chamber 001 is monitored in real time through the body 410. The operator can adjust the grinding parameters promptly based on the temperature data to avoid medicine quality problems caused by abnormal temperatures, thus improving the quality and stability of the medicine.

[0040] The following embodiments illustrate the details of the grinding machine pump head mechanism of this application by way of example.

[0041] Please refer to Figures 1-4 In this embodiment, optionally, the grinding mill pump head mechanism includes a housing 100, an end cap 200, a grinding head 300, and nine temperature probes 400. The end cap 200 is connected to the housing 100, and the two work together to define a sealed chamber. The grinding head 300 is rotatably mounted inside the housing 100 and is used to connect to a motor. There is an annular gap between the outer circumferential surface of the grinding head 300 and the inner circumferential surface of the housing 100, thus forming a grinding mill cavity 001, within which the medicine can move. The nine temperature probes 400 are all fixed to the end cap 200 and are evenly spaced around the circumference of the grinding mill cavity 001. By setting nine temperature probes 400, the temperature around the grinding mill cavity 001 can be monitored in real time, thus avoiding temperature monitoring blind spots and errors, thereby providing accurate and reliable temperature monitoring.

[0042] Please refer to Figure 2 Optionally, the housing 100 has an inner hole and a first open end and a second open end that are axially opposite each other in the inner hole. The first open end is provided with an annular outwardly folded flange. The second open end is used to connect with the motor housing 100, and the motor housing 100 is used to close the second open end.

[0043] Please refer to Figures 2-3Optionally, the end cap 200 includes a cap body 210, a positioning plate 220, and an annular fixing plate 230. The cap body 210 has a positioning groove, and the positioning plate 220 is embedded in the positioning groove. The fixing plate 230 can be fixed to the cap body 210 by bolts or other structural components. The fixing plate 230 and the cap body 210 cooperate to clamp the positioning plate 220. The cap body 210 is detachably connected to the outwardly folded edge by bolts or other means. The positioning plate 220 and the fixing plate 230 are clamped between the cap body 210 and the housing 100. By setting the end cap 200 as a split structure, the processing difficulty can be reduced and the processing efficiency improved.

[0044] Meanwhile, a discharge connector 240 and an exhaust port 250 are installed on the cover body 210. The discharge connector 240 can be welded to the cover body 210 and passes through the positioning plate 220. The discharge connector 240 is provided with a discharge hole, and a discharge screen is installed in the discharge hole. The mesh diameter of the discharge screen is designed as needed to allow the ground medicine that meets the particle size requirement to be discharged from the discharge screen. The exhaust port 250 can be welded to the cover body 210 and passes through the positioning plate 220. The exhaust port 250 is provided with an exhaust hole, and a blocking screen is installed in the exhaust hole. The mesh diameter of the blocking screen is designed as needed to allow steam to pass through but not allow medicine to pass through. In other words, when the pump head mechanism needs to be sterilized after use, high-temperature steam sterilization is generally used. The high-temperature steam enters the sealed chamber between the housing 100 and the end cover 200 and then exits from the exhaust hole.

[0045] It should be understood that since the cap body 210 and the housing 100 are detachably connected, it is convenient to open the end cap 200 before grinding and add the medicine into the housing 100.

[0046] Furthermore, the cover body 210 is provided with nine stepped holes 211, and correspondingly, the positioning plate 220 is provided with nine positioning holes 221. The nine stepped holes 211 and the nine positioning holes 221 are connected one-to-one. The body 410 of each temperature probe 400 can pass through the paired stepped holes 211 and positioning holes 221. The stepped hole 211 includes a first hole segment and a second hole segment that are connected. Both the first hole segment and the second hole segment are cylindrical holes. The diameter of the first hole segment is larger than the diameter of the second hole segment, so that an annular surface is formed between the hole walls of the first hole segment and the second hole segment. The diameter of the positioning hole 221 is approximately equal to the diameter of the second hole segment. The body 410 can pass through the first hole segment, the second hole segment, and the positioning hole 221 in sequence and extend into the grinding machine cavity 001.

[0047] In this embodiment, optionally, the grinding head 300 has a generally cylindrical structure. Multiple protrusions 310 are provided on the outer peripheral surface of the grinding head 300. Each protrusion 310 extends axially in the grinding head 300, and the multiple protrusions 310 are evenly spaced around the axis of the grinding head 300. The protrusions 310 have a gap with the inner peripheral surface of the housing 100, reducing friction and providing space for the movement of the medicine. During use, the protrusions 310 can contact the medicine and grind it.

[0048] Please refer to Figure 4 Optionally, the temperature probe 400 can be electrically connected to the processor via a data cable. The temperature probe 400 extends into the grinding chamber 001, acquiring temperature changes within the chamber and converting this information into an electrical signal, which is then transmitted to the processor. All temperature probes 400 can be electrically connected to one processor, which can communicate with a display screen. The information acquired by the temperature probes 400 is processed by the processor and displayed on the screen for easy and intuitive acquisition of temperature parameters. It should be understood that the structure of the temperature probe 400 can refer to existing known technologies; to avoid repetition, its principles and detailed structure are not described in detail in this embodiment. The temperature probe 400 can be powered by a battery.

[0049] It should be understood that in other embodiments, the number of temperature probes 400 is not limited to nine.

[0050] Furthermore, the temperature probe 400 may include a body 410 and a sheath 420. The sheath 420 is made of metal or plastic, and its hardness is greater than that of the body 410. The sheath 420 is fitted over the body 410 to protect it. In other words, during drug grinding, because the body 410 extends into the grinding chamber 001, and because it is long and has a small diameter, its own hardness is low. If the body 410 comes into direct contact with the drug, it may deform upon impact. This deformation could then easily lead to direct contact with the grinding head 300, resulting in damage. Installing the sheath 420 increases the hardness of the body 410, making it less susceptible to deformation from drug impacts and extending its service life.

[0051] It should be understood that the sheath 420 can be interference-fitted with the body 410, or the sheath 420 can be bonded to the body 410.

[0052] In addition, the sheath 420 can be configured as a cylindrical tube, so that when it comes into contact with the drug, the drug can leave the sheath 420 along the outer circumference of the sheath 420, reducing the impact on the sheath 420.

[0053] Optionally, the temperature probe 400 also includes a sealing ring 430, which is sleeved on the outside of the temperature probe 400 and clamped between the temperature probe 400 and the end cap 200. During assembly, the sealing ring 430 is located within the first hole section and in contact with the annular surface.

[0054] Optionally, the temperature probe 400 can be screwed into the first hole segment, which is simple to install and easy to disassemble. In this embodiment, the temperature probe 400 can be set as a wireless temperature probe. Obviously, in some embodiments, the temperature probe 400 can also be set as a wired probe, etc.

[0055] The grinding mill pump head mechanism provided in this embodiment can obtain the temperature inside the grinding mill cavity 001 in real time by setting a temperature probe 400 on the end cover 200, thereby adjusting the grinding parameters according to the temperature information and avoiding the impact of excessive temperature on the quality of medicine.

[0056] This embodiment also provides a grinding machine, which includes the grinding machine pump head mechanism of the above embodiment. Obviously, the grinding machine also includes other basic components for grinding, such as a motor. The motor housing can be connected to the housing 100, and the motor's rotating shaft can be connected to the grinding head 300. After the motor is started, it can drive the grinding head 300 to rotate relative to the housing 100.

[0057] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
