Description

Technical Field

[0001] This disclosure relates to the field of pressure monitoring technology for rubber stopper machines, and in particular to a pressure monitoring device for rubber stopper machines. Background Technology

[0002] Rubber stopper machines are commonly used in the pharmaceutical and food packaging industries. They accurately install rubber stoppers onto containers, such as medicine bottles, to achieve a seal. During the sealing process, the machine requires precise control of the pressure applied during stopper insertion and mold closure. Pressure fluctuations directly affect the seal quality, such as the stopper being too tight or too loose. Therefore, pressure monitoring devices are typically installed to maintain stable internal pressure within the machine.

[0003] Currently, traditional pressure monitoring devices for rubber stopper machines mainly use mechanical pressure controllers. However, the mechanical pressure controller suffers from a delay in mechanical action due to the spring reset time, resulting in the inability to release instantaneous overpressure in a timely manner, posing a significant safety hazard. Furthermore, mechanical pressure controllers cannot display real-time pressure values, failing to provide adequate monitoring of the rubber stopper machine's pressure. Utility Model Content

[0004] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a pressure monitoring device for a rubber stopper machine that reduces safety hazards, achieves better monitoring of the pressure of the rubber stopper machine, and ensures the reliable and stable operation of the intelligent digital display pressure controller.

[0005] The purpose of this disclosure is achieved through the following technical solution: A pressure monitoring device for a rubber stopper machine includes a rubber stopper machine body, a pressure sensor, and an electric pressure relief valve. The pressure sensor and the electric pressure relief valve are respectively disposed within a cavity of the rubber stopper machine body, and the electric pressure relief valve is connected to the cavity. The pressure monitoring device for the rubber stopper machine also includes an electrical cabinet and an intelligent digital display pressure controller. The intelligent digital display pressure controller is electrically connected and installed inside the electrical cabinet, and is electrically connected to the pressure sensor and the electric pressure relief valve respectively. The surface of the intelligent digital display pressure controller is respectively provided with a touch screen and a display screen. The display screen is used to display the pressure inside the cavity in real time, and the touch screen is used to adjust the pressure parameters inside the cavity.

[0006] In one embodiment, the pressure sensor is any one of a piezoresistive sensor, a piezoelectric sensor, or a capacitive sensor.

[0007] In one embodiment, the pressure monitoring device for the rubber stopper machine further includes a magnetic base with an installation cavity. The intelligent digital display pressure controller is installed in the installation cavity, and the magnetic base is magnetically connected to the metal partition of the electrical cabinet.

[0008] In one embodiment, the magnetic base includes a mounting plate and at least two magnetic components. The mounting plate has a mounting cavity in the middle, and each of the magnetic components is arranged around the mounting cavity.

[0009] In one embodiment, the magnetic elements are equidistantly distributed on the mounting plate.

[0010] In one embodiment, the mounting plate is either circular or square.

[0011] In one embodiment, the mounting plate has at least two recessed grooves on the side facing the metal partition, and each magnetic member is embedded in one of the recessed grooves.

[0012] In one embodiment, the number of mounting cavities is plurality, and the mounting cavities are staggered and arranged in the middle of the mounting plate; and / or, The electrical cabinet includes a metal box, a door, multiple metal partitions, and multiple component components. The metal box forms a receiving cavity. The door is rotatably disposed on one side of the metal box. The metal partitions are spaced apart in the receiving cavity to divide the receiving cavity into multiple layers of partitioned cavities. Each component component is correspondingly disposed in the partitioned cavity. The magnetic base is magnetically attached to the corresponding partitioned cavity.

[0013] In one embodiment, the pressure monitoring device for the rubber stopper machine further includes a sealing ring, wherein the mounting end of the pressure sensor is threaded to the inner wall of the cavity, and the sealing ring is embedded between the mounting end and the inner wall of the cavity.

[0014] In one embodiment, there are two electrically operated pressure relief valves, each located at the top of the cavity; and / or, The number of pressure sensors is multiple.

[0015] Compared with the prior art, this disclosure has at least the following advantages: 1) Compared to mechanical pressure controllers, intelligent digital display pressure controllers feature high-precision sensing, rapid response, and intelligent management. On one hand, when used with an electric pressure relief valve, they can quickly release instantaneous overpressure, effectively avoiding the problem of delayed mechanical structure action caused by the spring reset time in traditional mechanical pressure controllers, thus reducing safety hazards. On the other hand, the digital display pressure controller's screen can display the pressure inside the cavity in real time, enabling better monitoring of the rubber stopper machine pressure. Furthermore, the touchscreen of the digital display pressure controller allows operators to easily adjust the rubber stopper machine pressure parameters, further enhancing pressure monitoring and improving the intelligent management of the rubber stopper machine.

Detailed Implementation

[0019] To facilitate understanding of this disclosure, a more complete description will be given below with reference to the accompanying drawings, which illustrate preferred embodiments of the present disclosure. However, this disclosure can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure.

[0020] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments: Please refer to 1 to Figure 4One embodiment of the pressure monitoring device 10 for a rubber stopper machine includes a rubber stopper machine body 100, a pressure sensor 200, and an electric pressure relief valve 300. The pressure sensor 200 and the electric pressure relief valve 300 are respectively disposed within the cavity of the rubber stopper machine body 100, facilitating real-time acquisition of the internal pressure by the pressure sensor 200 and timely feedback of the acquired information to the intelligent digital display pressure controller 500. Furthermore, the electric pressure relief valve 300 is connected to the cavity, enabling it to operate according to the execution information of the intelligent digital display pressure controller 500, thereby releasing the pressure within the cavity in a timely manner, effectively... This avoids safety accidents caused by the inability to release instantaneous overpressure in time; the pressure monitoring device 10 for the rubber stopper machine also includes an electrical cabinet and an intelligent digital display pressure controller 500. The intelligent digital display pressure controller 500 is electrically connected and installed in the electrical cabinet, and is electrically connected to the pressure sensor 200 and the electric pressure relief valve 300 respectively; the surface of the intelligent digital display pressure controller 500 is respectively provided with a touch screen 520 and a display screen 510. The display screen 510 is used to display the pressure inside the cavity in real time, and the touch screen 520 is used to adjust the pressure parameters inside the cavity.

[0023] It is understandable that, compared to mechanical pressure controllers, the intelligent digital display pressure controller 500 features high-precision sensing, fast response, and intelligent management. On the one hand, when used in conjunction with the electric pressure relief valve 300, it can achieve rapid release of instantaneous overpressure, effectively avoiding the problem of delayed mechanical structure action caused by the spring reset time in traditional mechanical pressure controllers, which results in the inability to release instantaneous overpressure in a timely manner, thereby reducing safety hazards. On the other hand, the display screen 510 of the digital display pressure controller can realize real-time display of the pressure inside the cavity, thereby achieving better monitoring of the pressure of the rubber stopper machine. Furthermore, the touch screen 520 of the digital display pressure controller allows the operator to easily adjust the pressure parameters of the rubber stopper machine, further achieving better monitoring of the pressure of the rubber stopper machine and contributing to improved intelligent management of the rubber stopper machine.

[0024] Furthermore, since the intelligent digital display pressure controller 500 is electrically connected and housed within the electrical cabinet, the cabinet provides better protection and power to the controller, ensuring its normal operation and effectively blocking external contaminants, thus extending its lifespan. Additionally, the cabinet itself features shock absorption and heat dissipation design, reducing vibration and temperature interference with the controller's operation and ensuring reliable and stable operation. Specifically, the intelligent digital display pressure controller 500 is electrically connected to the power supply unit of the electrical cabinet.

[0025] When the rubber stopper machine is working, the pressure sensor 200 collects the pressure information inside the machine cavity and feeds it back to the control module of the intelligent digital display pressure controller 500 for processing. After processing, the control module obtains the real-time pressure information and sends real-time pressure display execution information to the display screen 510. The display screen 510 then activates according to the real-time pressure display execution information, so that the real-time pressure can be promptly reflected on the display screen 510 for the operator to observe and monitor. When the real-time pressure exceeds the preset value of the intelligent digital display pressure controller 500, the control module quickly sends pressure relief execution information to the electric pressure relief valve 300. The electric pressure relief valve 300 activates according to the pressure relief execution information to quickly relieve the pressure inside the cavity, thereby ensuring the normal pressure inside the cavity and realizing real-time monitoring of the rubber stopper machine pressure.

[0026] In addition, when the indicator light of the intelligent digital display pressure controller 500 is off, it serves as a reminder to the operator that the pressure of the intelligent digital display pressure controller 500 is not within a safe range. The operator can then manually release the pressure using this indicator light.

[0027] It should be noted that the specific structures of the electric pressure relief valve 300, the pressure sensor 200, the rubber stopper machine body 100, the method by which the pressure sensor 200 collects pressure information, the method by which the control module processes pressure information, the method by which the display screen 510 displays real-time pressure, the method by which the electric pressure relief valve 300 performs pressure relief, and the touch principle of the touch screen 520 are all existing technologies, therefore, they are not specifically described in this disclosure; and this disclosure only protects the connection relationship between the electric pressure relief valve 300, the pressure sensor 200, the rubber stopper machine body 100, and the intelligent digital display pressure controller 500.

[0028] In one embodiment, the pressure sensor 200 is any one of a piezoresistive sensor, a piezoelectric sensor, or a capacitive sensor. Since piezoresistive, piezoelectric, and capacitive sensors have high accuracy in acquiring pressure, they better ensure the accuracy of the acquired information, thereby guaranteeing the real-time monitoring accuracy of the intelligent digital display pressure controller 500. It is worth mentioning that since piezoresistive, piezoelectric, and capacitive sensors are existing technologies, they will not be specifically described in this disclosure.

[0029] like Figure 2 and Figure 3As shown, in one embodiment, the electrical cabinet includes a metal enclosure 420, a door 430, multiple metal partitions 410, and multiple component assemblies 440. The metal enclosure 420 forms a receiving cavity 421. The door 430 is rotatably disposed on one side of the metal enclosure 420, enabling the door 430 and the metal enclosure 420 to be rotated, thereby realizing the opening and closing of the door 430 and the metal enclosure 420. Each of the metal partitions 410 is spaced apart in the receiving cavity 420. 21, to divide the receiving cavity 421 into multiple partition cavities 4211, each of the component components 440 is correspondingly disposed in the partition cavity 4211, so that each component component 440 can be correspondingly disposed in the partition cavity 4211; the magnetic seat 600 is magnetically disposed on the corresponding partition cavity 4211; so that the operator can install the intelligent digital display pressure controller 500 on the corresponding partition cavity 4211 according to actual needs, thereby realizing the magnetic fixation of the intelligent digital display pressure controller 500.

[0030] It is understandable that in practical applications, when the spacing of the partitions 4211 on each layer of the electrical cabinet is much larger than the height of the intelligent digital display pressure controller 500, the bottom of the installed intelligent digital display pressure controller 500 is suspended in the partition 4211, that is, the intelligent digital display pressure controller 500 is only fixed by the upper connecting wire. However, since the intelligent digital display pressure controller 500 has a certain weight, the upper connecting wire of the intelligent digital display pressure controller 500 is prone to breakage after long-term use.

[0031] Therefore, as Figure 3 and Figure 4 As shown, in one embodiment, the pressure monitoring device 10 for the rubber stopper machine further includes a magnetic base 600, which forms a mounting cavity 611. The intelligent digital display pressure controller 500 is fitted into the mounting cavity 611. The magnetic base 600 is magnetically connected to the metal partition 410 of the electrical cabinet, so that the added magnetic base 600 can provide better support for the intelligent digital display pressure controller 500, effectively reducing the stress on the upper connecting wire of the intelligent digital display pressure controller 500, thereby reducing the probability of breakage of the upper connecting wire of the intelligent digital display pressure controller 500 under long-term use.

[0032] It is also understandable that, since the magnetic base 600 and the metal partition 410 are connected by magnetic attraction, it is not only convenient to operate, but also easy for the operator to quickly and repeatedly disassemble and assemble. This design effectively ensures the installation efficiency of the intelligent digital display pressure controller 500 and avoids the rework difficulties caused by misinstallation in the traditional installation method.

[0033] In addition, when the operator closes the door 430 of the electrical cabinet, the magnetic base 600 will move and adjust slightly under the action of external force, thus ensuring that the door 430 of the electrical cabinet will not fail to close due to the addition of the magnetic base 600.

[0034] In one embodiment, the size of the intelligent digital display pressure controller 500 and the size of the magnetic base 600 are not greater than the size of the remaining space of the corresponding partition cavity 4211 where the intelligent digital display pressure controller 500 is placed, thereby ensuring that the intelligent digital display pressure controller 500 and the magnetic base 600 can be well housed in the electrical cabinet box, thereby ensuring the tightness of the closure of the door 430 of the electrical cabinet box.

[0035] It is worth mentioning that, in this embodiment, the size of the remaining space of the partition cavity 4211 refers to the length, width, and height of the intelligent digital display pressure controller 500 and the magnetic base 600 after the electrical cabinet box has been equipped with multiple sets of component assemblies 440. These dimensions are all no greater than the length, width, and height of the remaining space of the partition cavity 4211 where the intelligent digital display pressure controller 500 is placed. This ensures the compatibility between the intelligent digital display pressure controller 500, the magnetic base 600 and the remaining space of the partition cavity 4211 where the intelligent digital display pressure controller 500 is placed, thereby ensuring that the electrical cabinet box will not have the problem of the door 430 not being able to close due to the addition of the intelligent digital display pressure controller 500 and the magnetic base 600.

[0036] like Figure 4 and Figure 5 As shown, in one embodiment, the magnetic base 600 includes a mounting plate 610 and at least two magnetic members 620. The mounting plate 610 has a mounting cavity 611 in its center, which can accommodate the intelligent digital display pressure controller 500. Since each of the magnetic members 620 is arranged around the mounting cavity 611, the magnetic base 600 is magnetically attached. Furthermore, the centrally located mounting cavity 611 better ensures the stable and reliable connection between the intelligent digital display pressure controller 500 and the mounting plate 610.

[0037] In one embodiment, the mounting cavity 611 is disposed through the mounting plate 610, so that the heat generated by the operation of the intelligent digital display pressure controller 500 can be dissipated to the metal partition plate 410 through the mounting cavity 611, thereby improving the heat dissipation performance of the intelligent digital display pressure controller 500.

[0038] In one embodiment, each of the magnetic components 620 is equidistantly distributed on the mounting plate 610 to ensure that the magnetic base 600 is provided with magnetic components 620 in all 360 degrees, so as to better adapt to the magnetic fixation of the intelligent digital display pressure controller 500 at different angles.

[0039] In one embodiment, the mounting plate 610 is either circular or square. Since a square shape is compatible with a conventional intelligent digital display pressure controller 500, the square mounting plate 610 can better match the shape of the intelligent digital display pressure controller 500, thereby ensuring the flatness and aesthetics after assembly. Since a circular mounting plate 610 has no sharp edges or corners, it ensures that the operator or other components of the electrical cabinet are not easily scratched during installation.

[0040] In one embodiment, the mounting plate 610 has at least two recessed grooves on the side facing the metal partition 410, and each magnetic member 620 is embedded in one of the recessed grooves to achieve the fitting of the magnetic member 620 with the mounting plate 610.

[0041] In one embodiment, the end of the magnetic 620 is flush with the side of the mounting plate 610 facing the metal partition 410, which better ensures the stability of the magnetic connection between the mounting plate 610 and the metal partition 410, and effectively avoids the problem that the exposed magnetic 620 causes the mounting plate 610 to be uneven, thus affecting the stability of the magnetic connection between the mounting plate 610 and the metal partition 410.

[0042] In one embodiment, there are multiple mounting cavities 611, which are staggered in the middle of the mounting plate 610. This allows the additional mounting cavities 611 to provide multiple different angles for the intelligent digital display pressure controller 500, so as to better adapt to the installation requirements of the remaining space of different partition cavities 4211.

[0043] In one embodiment, the pressure monitoring device 10 for the rubber stopper machine further includes a sealing ring. The mounting end of the pressure sensor 200 is threaded to the inner wall of the cavity, and the sealing ring is embedded between the mounting end and the inner wall of the cavity to achieve a sealed and fixed arrangement between the pressure sensor 200 and the inner wall of the cavity.

[0044] In one embodiment, the number of pressure sensors 200 is multiple, so as to achieve accurate monitoring of the pressure in the cavity and effectively avoid the problem of inaccurate monitoring caused by a single pressure sensor 200.

[0045] In one embodiment, multiple pressure sensors 200 are arranged near the pressing head, cleaning chamber, and sterilization chamber of the rubber stopper machine body 100 to achieve better monitoring of the pressure inside the pressing head, cleaning chamber, and sterilization chamber of the rubber stopper machine body 100.

[0046] Specifically, the rubber stopper machine body 100 includes a pressing area, a sterilization chamber, and a cleaning chamber. The pressing area is equipped with a pressing head. At least two pressure sensors 200 are respectively installed in the pressing head, the cleaning chamber, and the sterilization chamber, thereby enabling better monitoring of the pressure inside the pressing head, the cleaning chamber, and the sterilization chamber of the stopper machine body. Since the specific structure of the rubber stopper machine body 100 is prior art, it will not be described in detail in this disclosure.

[0047] like Figure 1 As shown, in one embodiment, there are two electric pressure relief valves 300, which are respectively disposed on the top of the cavity to achieve rapid release of pressure in the cavity, and at the same time effectively avoid safety problems caused by the failure of a single electric pressure relief valve 300.

[0048] In one embodiment, the electric pressure relief valve 300 is sealed and fixedly connected to the inner wall of the cavity via a flange 700.

[0049] Specifically, in one embodiment, the electric pressure relief valve 300 is fitted into the mounting opening on the inner side wall of the cavity, forming a connection point. A flange 700 is fitted into this connection point to seal it, thereby achieving a sealed fixation between the electric pressure relief valve 300 and the cavity. Since the structure of the flange 700 is prior art, it will not be described in detail in this disclosure. Of course, those skilled in the art can also achieve a sealed fixation between the electric pressure relief valve 300 and the cavity using other similar sealing structures.

[0050] Compared with the prior art, this disclosure has at least the following advantages: 1) Compared to mechanical pressure controllers, the intelligent digital display pressure controller 500 features high-precision sensing, fast response, and intelligent management. On one hand, when used in conjunction with the electric pressure relief valve 300, it enables rapid release of instantaneous overpressure, effectively avoiding the problem of delayed mechanical structure action caused by the spring reset time in traditional mechanical pressure controllers, thus reducing safety hazards. On the other hand, the display screen 510 of the digital pressure controller can display the pressure inside the cavity in real time, enabling better monitoring of the pressure in the rubber stopper machine. Furthermore, the touch screen 520 of the digital pressure controller allows operators to easily adjust the pressure parameters of the rubber stopper machine, further enhancing the monitoring of the pressure and improving the intelligent management of the rubber stopper machine.

[0051] 2) Since the intelligent digital display pressure controller 500 is electrically connected and installed inside the electrical cabinet, the electrical cabinet provides better protection and power to the intelligent digital display pressure controller 500, ensuring its normal operation. It also effectively blocks external contaminants and extends the lifespan of the intelligent digital display pressure controller 500. Furthermore, since the electrical cabinet itself has shock absorption and heat dissipation functions, it reduces the interference of vibration and temperature on the operation of the intelligent digital display pressure controller 500, thereby ensuring the reliable and stable operation of the intelligent digital display pressure controller 500.

[0052] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
