Description

Technical Field

[0001] This utility model relates to the field of cigarette processing, specifically a compression strength tester with protective function. Background Technology

[0002] The compression strength test is used to evaluate the ability of a cigarette filter to resist deformation under axial pressure. Its core function is to verify the structural integrity and compressive strength of the filter by quantifying its deformation threshold under stress. In the specific test, specialized equipment is used to apply pressure, record the compression deformation versus recovery force curve, and calculate key indicators such as the percentage of compression recovery.

[0003] In existing technologies, when processing and manufacturing cigarettes, it is necessary to first test the strength of their components, such as filters and cigarette cases, to ensure that they have sufficient strength during transportation and daily use, and are not easily deformed or damaged during use or transportation. Generally, when testing the compressive strength of components, they are placed inside a transparent box and compressed using hydraulic rods, cylinders, or other equipment. The applied pressure is then displayed by a pressure detector, making it easy for staff to record and judge the strength. However, when testing items through a transparent box, some components are prone to breakage due to excessive pressure or non-compliance with standards, resulting in fragments. Although the transparent glass box can protect staff, after long-term use, the transparent glass box is prone to scratches and dents from repeated impacts from the flying broken components, which can affect the staff's ability to record and judge the data on the pressure display. Utility Model Content

[0004] To address the shortcomings of existing technologies, when testing items through a transparent enclosure, some components are prone to breakage due to excessive pressure or non-compliance with standards, resulting in fragmentation. Although the transparent glass enclosure can protect workers, after prolonged use, it is susceptible to scratches and dents from repeated impacts from flying broken components, affecting workers' ability to record and interpret data from the pressure display. This invention proposes a compressive strength tester with protective functions.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a compressive strength tester with protective function, including a test chamber, a cylinder fixedly connected to the top of the test chamber, the output end of the cylinder passing through the test chamber and fixedly connected to an installation block, a pressure display fixedly connected to the bottom of the installation block, a pressure block fixedly connected to the bottom of the pressure display, a base plate fixedly connected to the inner cavity of the test chamber, a vertical plate fixedly connected to the top of the base plate, and a protective mechanism provided in the inner cavity of the test chamber;

[0006] The protective mechanism includes a rotating shaft, the surface of which is rotatably connected to the inner cavity of the upright plate. A connecting rotating plate is fixedly connected to the surface of the rotating shaft. An installation rod is rotatably connected to the inner cavity of the connecting rotating plate. A rotating plate is rotatably connected to the surface of the installation rod. A connecting shaft is rotatably connected to the inner cavity of the rotating plate. A sliding groove and an arc-shaped groove are provided on one side of the upright plate. The surface of the connecting shaft is slidably connected to the inner cavity of the sliding groove and the arc-shaped groove. A rotating plate is rotatably connected to the surface of the connecting shaft. A connecting rod is rotatably connected to the inner cavity of the rotating plate. A slider is rotatably connected to one end of the connecting rod. The surface of the slider is slidably connected to the inner cavity of the sliding groove. A connecting plate is fixedly connected to one side of the rotating plate. A fixing plate is fixedly connected to one side of the connecting plate. A transparent protective plate is movably engaged on one side of the fixing plate. A driving assembly is provided on one side of the upright plate.

[0007] The drive assembly includes a mounting plate, one side of which is fixedly connected to one side of the upright plate. A servo motor is fixedly connected to one side of the mounting plate, and the output end of the servo motor passes through the mounting plate and is fixedly connected to one end of the rotating shaft.

[0008] Preferably, a locking block is fixedly connected to one side of the fixing plate, and a locking groove is opened on one side of the transparent protective plate, with the surface of the locking block movably engaging with the inner cavity of the locking groove.

[0009] Preferably, a reinforcing ring block is fixedly connected to the surface of the rotating shaft, and one side of the reinforcing ring block is rotatably connected to one side of the upright plate.

[0010] Preferably, a spring is fixedly connected to one side of the upright plate, and an inclined block is fixedly connected to one end of the spring.

[0011] Preferably, a limiting rod is fixedly connected to one side of the upright plate, the surface of the limiting rod is slidably connected to the inner cavity of the inclined block, and the surface of the spring is sleeved on the surface of the limiting rod.

[0012] Preferably, a sliding plate is slidably connected to the top of the base plate, and a rotating door is rotatably connected to one side of the test chamber, with a transparent glass fixedly connected to the inner cavity of the rotating door.

[0013] The advantages of this utility model are:

[0014] This invention utilizes a servo motor to drive a rotating shaft, which in turn rotates a rotating plate. This plate rotates the transparent protective plate, which then moves downwards after reaching a certain angle, effectively covering the object being tested. This design prevents damage, dents, and scratches to the inner wall of the test chamber and the transparent glass in the event of breakage or debris during testing. This allows the test chamber and transparent glass to be used for a long time without significantly affecting the reading of the pressure display. Furthermore, replacing the transparent protective plate is simple, convenient, and inexpensive. This invention solves the problem that when testing items through a transparent chamber, some components are prone to breakage due to high pressure or non-standard conditions, resulting in debris scattering. While the transparent glass chamber provides protection for personnel, over time, repeated impacts from flying broken components can cause scratches and dents, affecting the recording and interpretation of pressure display data.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0026] This application discloses a compressive strength testing instrument with protective functions. (Refer to...) Figure 1 and Figure 2 A compressive strength tester with protective function includes a test chamber 1, a cylinder 2 fixedly connected to the top of the test chamber 1, the output end of the cylinder 2 passing through the test chamber 1 and fixedly connected to a mounting block 5, a pressure display 3 fixedly connected to the bottom of the mounting block 5, a pressure block 4 fixedly connected to the bottom of the pressure display 3, a base plate 7 fixedly connected to the inner cavity of the test chamber 1, a vertical plate 8 fixedly connected to the top of the base plate 7, and a protective mechanism 9 provided in the inner cavity of the test chamber 1.

[0027] The test chamber 1 can be connected to the mounting block 5 via the cylinder 2. The mounting block 5 can install and fix the pressure display 3, and at the same time, connect the pressure block 4 via the pressure display 3. When the cylinder 2 is operating, it can smoothly drive the pressure display 3 and the pressure block 4 to move downwards, and the pressure block 4 squeezes the object to be tested. The pressure display 3 displays the pressure value of the squeeze. The test chamber 1 can be connected to the upright plate 8 via the base plate 7. The upright plate 8 can be used to install the protective mechanism 9, and the protective mechanism 9 covers and protects the object to be tested, reducing the damage to the inner wall of the test chamber 1 when the object breaks and produces flying debris. At the same time, the pressure display 3 can be selected according to different models, such as Borgwaldt-DD60A.

[0028] The protective mechanism 9 includes a rotating shaft 901, the surface of which is rotatably connected to the inner cavity of the upright plate 8. A connecting rotating plate 902 is fixedly connected to the surface of the rotating shaft 901. An installation rod 903 is rotatably connected to the inner cavity of the connecting rotating plate 902. A rotating plate 904 is rotatably connected to the surface of the installation rod 903. A connecting shaft 905 is rotatably connected to the inner cavity of the rotating plate 904. A sliding groove 909 and an arc-shaped groove 910 are provided on one side of the upright plate 8. The surface of the connecting shaft 905 is slidably connected to the inner cavity of the sliding groove 909 and the arc-shaped groove 910. A rotating plate 906 is rotatably connected to the surface of the connecting shaft 905. A connecting rod 907 is rotatably connected to the inner cavity of the rotating plate 906. A slider 908 is rotatably connected to one end of the connecting rod 907. The surface of the slider 908 is slidably connected to the inner cavity of the sliding groove 909. A connecting plate 911 is fixedly connected to one side of the rotating plate 906.

[0029] In addition, a fixing plate 912 is fixedly connected to one side of the connecting plate 911, and a transparent protective plate 914 is movably snapped onto one side of the fixing plate 912. A drive assembly 913 is provided on one side of the upright plate 8. The upright plate 8 can be connected to the connecting rotating plate 902 via the rotating shaft 901, and the connecting rotating plate 902 can be installed and connected to the rotating plate 904 via the mounting rod 903. The connecting shaft 905 connected to the inner cavity of the rotating plate 904 can slide in the inner cavities of the arc groove 910 and the slide groove 909, and the slide groove 909 is connected to the inner cavity of the arc groove 910. When the rotating shaft 901 rotates, it can smoothly drive the mounting rod 903 to rotate via the connecting rotating plate 902. Due to the connection between the mounting rod 903 and the rotating plate 904, and the rotation... The connection between plate 904 and connecting shaft 905 allows for smooth pushing of connecting shaft 905, enabling it to slide within arc groove 910. Since arc groove 910 is arc-shaped and rotating plate 906 is connected to connecting shaft 905 and connecting plate 911, rotating plate 906 can smoothly drive connecting plate 911, fixed plate 912, and transparent protective plate 914 to rotate. After rotation, the transparent protective plate 914 moves downwards, thus covering and protecting the object. Simultaneously, the connection between slider 908 and connecting rod 907, and the sliding of slider 908 within groove 909, allow for smoother and more stable downward movement and rotation of connecting plate 911, thereby achieving object shielding.

[0030] In addition, the drive assembly 913 includes a mounting plate 9131, one side of which is fixedly connected to one side of the upright plate 8. A servo motor 9132 is fixedly connected to one side of the mounting plate 9131. The output end of the servo motor 9132 passes through the mounting plate 9131 and is fixedly connected to one end of the rotating shaft 901. The upright plate 8 can use the mounting plate 9131 to install and fix the servo motor 9132. The servo motor 9132 can smoothly drive the rotating shaft 901 to rotate during operation, thereby realizing the rotation and up-down movement of the transparent protective plate 914.

[0031] Reference Figure 7 A locking block 15 is fixedly connected to one side of the fixed plate 912, and a locking groove 14 is provided on one side of the transparent protective plate 914. The surface of the locking block 15 is movably engaged with the inner cavity of the locking groove 14. The setting of the locking groove 14 and the locking block 15 allows the staff to easily and simply replace the transparent protective plate 914. Thus, if the transparent protective plate 914 becomes worn and unclear due to flying debris after long-term use, the staff can easily replace it.

[0032] Reference Figure 6A reinforcing ring 16 is fixedly connected to the surface of the rotating shaft 901. One side of the reinforcing ring 16 is rotatably connected to one side of the upright plate 8. The reinforcing ring 16 can increase the stability of the rotating shaft 901 during use, making it stable enough during rotation and use, and not only is it not easy to shake, but it is also not easy to tilt.

[0033] Reference Figure 4 and Figure 5 A spring 11 is fixedly connected to one side of the upright plate 8, and a wedge block 12 is fixedly connected to one end of the spring 11. The upright plate 8 can be connected to the wedge block 12 through the spring 11. When the operator drives the rotating shaft 901 and the slider 908 to rotate by the servo motor 9132, the operator can observe the degree of contact between the slider 908 and the inclined surface of the wedge block 12. When the slider 908 and the inclined surface of the wedge block 12 are in contact, the operation of the servo motor 9132 can be stopped, so that the transparent protective plate 914 moves up to the appropriate position. This reduces the inconvenience of adding, taking out, or replacing objects when the operator needs to take out or replace objects because the upward distance of the transparent protective plate 914 is too short.

[0034] Reference Figure 4 and Figure 5 A limiting rod 13 is fixedly connected to one side of the upright plate 8. The surface of the limiting rod 13 is slidably connected to the inner cavity of the inclined block 12. The surface of the spring 11 is sleeved on the surface of the limiting rod 13. The setting of the limiting rod 13 can effectively increase the stability of the inclined block 12 in vertical movement and reduce the deformation of the spring 11 when it is extended or retracted.

[0035] Reference Figure 1 and Figure 2 A sliding plate 17 is slidably connected to the top of the base plate 7. A rotating door 6 is rotatably connected to one side of the test chamber 1. A transparent glass 10 is fixedly connected to the inner cavity of the rotating door 6. The sliding plate 17 can push the debris covered inside the transparent protective plate 914, making it convenient for staff to clean and handle it uniformly afterward. The rotating door 6 can open and close the test chamber 1, while the transparent glass 10 can cooperate with the transparent protective plate 914 to facilitate staff to observe and record the data of the pressure display 3.

[0036] Working Principle: When using this device, the operator can place the object requiring strength testing on top of the base plate 7. Then, the mounting plate 9131 is activated. The operation of the mounting plate 9131 drives the rotating shaft 901 to rotate. When the rotating shaft 901 rotates, it drives the rotating plate 904 to rotate and move downwards via the connecting plate 902 and the mounting rod 903. As the rotating plate 904 rotates and moves, it drives the connecting shaft 905 to slide inside the arc-shaped groove 910. Because the arc-shaped groove 910 is arc-shaped, the connecting shaft 905 can drive the rotating plate 906 to rotate downwards, thereby driving the transparent... The protective plate 914 rotates together. After the connecting shaft 905 rotates to a certain angle, it will slide out from the inside of the arc groove 910 and slide into the inside of the slide groove 909. At this time, the subsequent rotation of the connecting rotating plate 902 can push the slider 908 and the rotating plate 906 to slide downward, thereby driving the transparent protective plate 914 to move downward together, so as to cover the object to be tested and inspected. Then, by starting the cylinder 2, the pressure block 4 is driven to move downward. After the pressure block 4 moves downward to a certain distance, it can squeeze the object. The data can be recorded by observing the data on the pressure display 3.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
