Description

Technical Field

[0001] This utility model relates to the field of pressure detection technology, specifically to a precision pressure testing device. Background Technology

[0002] In some cosmetic bottling containers, an inner stopper is installed at the bottle opening to restrict other components within the internal material cavity. For example, a stirring component might be installed within the material cavity to agitate the product, effectively preventing stratification or sedimentation. The stirring component is confined within the material cavity by the inner stopper at the bottle opening. A brush on the bottle cap passes through the inner stopper and works in conjunction with the stirring component. The brush's rod drives the stirring component to rotate within the material cavity, thus agitating and lifting the cosmetic product.

[0003] The outer wall of the inner stopper and the inner wall of the bottle neck are typically fitted together using protrusions and recesses to secure the inner stopper in place. Currently, inner stoppers are usually installed manually by pressing them into the bottle neck. This manual installation is inefficient and can easily contaminate the cosmetic product inside the bottle's filling chamber.

[0004] Therefore, to improve production efficiency and avoid contamination of the cosmetic material inside the bottle, mechanized automated production lines are generally used. These lines employ power units to drive pressure plates / blocks, pressing the inner stopper into the bottle neck. However, mechanized assembly presents a pressure issue: excessive pressure can damage the bottle and inner stopper, breaking the bottle; insufficient pressure can result in the inner stopper not being properly installed. Furthermore, the required pressure varies depending on the material and size of the bottle and inner stopper.

[0005] Therefore, a practical and precise inner plug pressure testing device is needed to obtain the actual pressure data of inner plugs of different specifications installed in the bottle mouth before production testing, in order to solve the above problems. Utility Model Content

[0012] The pressure sensor is mounted on the base plate via a protective block. The upper end of the protective block is regularly provided with sensor mounting holes for mounting the pressure sensor.

The pressure sensor and the base are regularly mounted on the lower base plate, and the power device is regularly mounted on the upper base plate.

[0017] Furthermore, an adapter plate is regularly installed on the upper end of the upper base plate. The adapter plate is vertically arranged in the space of the upper base plate and is located between the motor and the lead screw. The front side of the adapter plate is used to install a slide rail, and the pressure plate slides smoothly on the slide rail via a slider.

[0018] Furthermore, a limit sensor assembly for limit detection is regularly installed between the adapter plate and the pressure plate.

[0019] Furthermore, a top plate is installed at the upper four corners of the base plate by means of columns or profiles to form the frame of the precision pressure testing device.

[0031] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0032] 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 invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] like Figure 1-3As shown, this utility model provides a precision pressure testing device, including a base plate, a power unit, a pressing head 7, a base 8, and a pressure sensor 11. The base 8 and pressure sensor 11 are mounted on the base plate. The pressure sensor 11 is located at the lower end of the base 8 and is used to detect the pressure from the base 8. The upper end of the base 8 has a regularly arranged inner cavity 801 for installing an inner plug. The pressing head 7 is located directly above the base 8 and is driven by the power unit to press down, pressing the inner plug at the upper end of the base 8 into the inner cavity 801. The base 8 transmits pressure to the pressure sensor 11, which collects the pressure data of the inner plug installed in the base 8.

[0034] This invention, through the cooperation of the pressure head 7, the base 8, and the pressure sensor 11, can accurately collect pressure data of inner plugs of different specifications installed in the bottle mouth, thereby providing strong data support for subsequent automated production, avoiding a series of problems caused by excessive or insufficient pressure when installing inner plugs on automated production lines, as well as a series of problems caused by production switching.

[0035] Further, such as Figure 2 As shown, in order to conduct pressure tests on inner plugs of different shapes and obtain pressure data when inner plugs of different specifications are installed in the bottle neck, the base 8 adopts a detachable design and is installed on the upper end of the pressure sensor 11 via the base connector 12. Meanwhile, to prevent excessive pressure from damaging the pressure sensor 11, the base connector 12 and the pressure sensor 11 are installed in the protective block 9.

[0036] Furthermore, the base connector 12, serving as an adapter between the base 8 and the pressure sensor 11, has a lower magnet and a positioning pin 13 regularly arranged at its upper end. At the position of the lower magnet and positioning pin 13, the lower end of the base 8 has an upper magnet and a positioning hole for the positioning pin 13 to insert and engage. Thus, through the engagement of the positioning pin and positioning hole, and the two magnets, the base 8 is stably mounted and fixed to the upper end of the base connector 12, facilitating the installation and quick replacement of the base 8. For inner plugs of different shapes, we only need to change the specifications of the inner cavity 801 at the upper end of the base 8, designing bases of different specifications to quickly perform pressure tests on inner plugs of different specifications.

[0037] Further, such as Figure 1 As shown, in one embodiment, the power unit uses a motor 2 as the power unit for the lower pressure head 7. The motor 2 is mounted and fixed above the lower base plate 101 via an upper base plate 103 and several support columns 102. The pressure sensor 11 is mounted and fixed on the upper surface of the lower base plate 101 via a protective block 9, and the base 8 is mounted and fixed on the upper end of the pressure sensor 11 via a base connector 12.

[0038] Furthermore, to improve the testing accuracy of the pressure testing device, motor 2 drives the lower pressure head 7 via lead screw 3. The shaft of motor 2 is connected to the screw of lead screw 3, thereby driving the screw of lead screw 3 to rotate. The lower pressure head 7 is connected to the nut of lead screw 3 via pressure plate 6, thus converting the rotational motion of the screw of lead screw 3 into its linear motion, thereby realizing the up-and-down movement of the lower pressure head. Motor 2 drives pressure plate 6 to move up and down via lead screw 3, and pressure plate 6 synchronously drives the lower pressure head 7 to move up and down above the base 8.

[0039] The aforementioned motor and the screw of lead screw 3 are directly connected by a coupling, thereby mounting the motor 2 above or below lead screw 3. In other embodiments, such as Figure 1 As shown, a pair of pulleys and a belt can be used to arrange the motor 2 and the lead screw 3 side by side, with the motor 2 installed behind the lead screw 3.

[0040] Furthermore, in order to improve the stability of the lower pressure head 7 when it slides up and down, the left and right sides of the pressure plate 6 are connected by sliders 5 and slide rails 4 to make the pressure plate 6 slide stably on the slide rails 4.

[0041] Further, such as Figure 1 As shown, an adapter plate 104 is regularly arranged on the upper end of the upper base plate 103. The adapter plate 104 is vertically arranged in the space of the upper base plate 103 and is located between the motor 2 and the lead screw 3. It is used to install a pair of slide rails 4. The pair of slide rails 4 are installed parallel to each other on the front side of the adapter plate 104. The pressure plate 6 slides on the slide rails 4 through a pair of sliders 5.

[0042] Further, such as Figure 1 As shown, a limit sensor assembly 10 for limit detection is also regularly installed between the adapter plate 104 and the pressure plate 6.

[0043] like Figure 3 As shown, a top plate 106 is installed on the upper end of the four corners of the base plate 101 by columns 105. The base plate 101 and the top plate 106 are encapsulated by several side panels 107 to form the frame and shell of the test device.

[0044] Furthermore, the front end of the base plate 101 extends forward to form a base plate extension 1011. The base 8 and the protective block 9 are mounted on the upper end of the top plate extension 1011 and are positioned on the outside of the front panel 108 via the base plate extension 1011. The pressure head 7 extends out of the front panel 108 and is positioned above the base 8.

[0045] Furthermore, the front panel 108 is provided with a vertical slot in the direction of movement of the pressing head 7 to facilitate the sliding of the pressing head up and down.

[0046] Further, such as Figure 3As shown, the front panel 108 also features a display screen 14, a control panel 15, and a start switch 16. The display screen 14 shows the testing process and test results such as the current pressure value and peak pressure. The control panel 15 is used to set parameters such as the lifting speed of the pressure head and the testing distance. The start switch 16 controls the start of the testing device.

[0047] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
