Description

Technical Field

[0001] The present invention relates to the field of detection equipment, and in particular to a solid medicine detection equipment. Background Art

[0002] The types of medicines in pharmacy can be mainly divided into liquid medicines and solid medicines according to their state; among them, solid medicines can be further divided into powder medicines, hard tablet medicines and capsule medicines. Each medicine needs to be sampled and tested during the batch production process to ensure the quality of the same batch of medicines. Among them, one of the sampling tests for solid hard tablet medicines is the extrusion strength test, which is used to determine the hardness of the solid hard tablet.

[0003] The specific operation is that the tablet to be tested is placed in the middle test area, and the extrusion parts on both sides move toward the middle and apply pressure to the tablet. The degree of pressure on the tablet will change with the change of operation, and the pressure it withstands ranges from 2000Pa to 20000Pa until the tablet is crushed under pressure. The equipment stops pressurizing, records and determines whether the pressure value meets the standard.

[0004] Among them, during the test process, after a single extrusion is completed, there will be tablet residues adhering to the surface of the extrusion component (the tablet is partially compressed, increasing its adhesion to the working surface of the extrusion component. As the tablet is broken, the tablet is still partially attached to the working surface of the extrusion component and cannot fall off). As the next extrusion work proceeds, if the adhered tablet residue contacts the tablet to be tested (the tablet residue and the tablet to be tested are not the same sample), then when it is squeezed, the tablet residue will cause concentrated stress inside the tablet to be tested, resulting in the tablet to be tested not reaching the test pressure and breaking, and then being marked as a poor quality sample, causing detection errors.

[0005] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the invention

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] See also Figure 1 and Figure 2 The present invention provides a solid medicine detection device, which includes a placement platform 1 placed in a space to be tested 00, a pressure block 2 arranged on at least one side of the space to be tested 00 and moving along the working surface of the placement platform 1 (the upper surface of the placement platform 1), the pressure block 2 is slidably installed on the frame 03 and is driven by a moving drive component (the moving drive component is generally an electric cylinder or a cylinder equipped with a pressure sensor) to move (the moving drive component of the pressure block 2 is an existing structure and is not the innovation of the present application, so it is not described in detail in the text and the drawings), the moving pressure block 2 squeezes the space to be tested (the volume of the space to be tested is reduced), in this embodiment, the pressure block 2 is provided with two blocks and is respectively placed on both sides of the space to be tested 00, when squeezing, the two pressure blocks 2 squeeze the space to be tested in a centered moving manner.

[0026] See also Figure 2 and Figure 3 During the test, the tablet is placed on the placement platform 1, and then the two pressure blocks 2 move in alignment and apply pressure to the tablet. The value of the pressure sensor gradually increases. When the tablet breaks instantly (the value of the pressure sensor decreases instantly), the pressure block 2 stops moving, then moves and resets, and finally records the value of the pressure sensor before it decreases instantly.

[0027] The frame 03 is also hinged with an upper cover 02 for buckling and closing the space to be tested 00. During the test process, the upper cover 02 is used to buckle and close the space to be tested 00 to increase the safety of the equipment working environment.

[0028] The test space 00 has a discharge port 01, from which the crushed tablets are discharged after the test is completed.

[0029] See also Figure 1 and Figure 3 , the placing platform 1 can enter the discharging state from the working state. The specific switching process is that the placing platform 1 changes its angle around a predetermined axis toward the discharging port 01 to form a state where the position away from the discharging port 01 is high and the position close to the discharging port 01 is low. In this state, the broken tablets slide out of the device from the discharging port 01 along the inclined surface formed by the placing platform 1 under the action of their own weight. The placing platform 1 in the working state is in a horizontal state, and the inclination angle of the placing platform 1 in the discharging state is 45~60°.

[0030] The placement platform 1 is installed in the test space 00 in an end-hinged manner and is driven by a driving component to perform angle switching; see Figure 7 The driving assembly includes a driving space arranged below the placement platform 1, a rotating member 3 rotatably installed in the driving space, and a connecting member 4 connecting the rotating member 3 and the placement platform 1; the rotating member 3 is a disc or a cam structure, and is driven by a driver (a motor) to rotate, and the connecting member 4 is a connecting rod. One end of the connecting member 4 is eccentrically installed on the rotating member 3, and the other end is installed at a predetermined position of the placement platform 1.

[0031] When driving the placement platform 1 to switch its state, the driver drives the rotating member 3 to rotate, and utilizes the continuous change of the position of the eccentric connection point driven by the rotation of the rotating member 3, thereby driving the angle switching of the placement platform 1 through the connecting member 4.

[0032] See also Figure 4 , Figure 5 and Figure 6 The placement platform 1 has a side surface corresponding to the extrusion end surface of the pressure block 2, and the side surface is equipped with a scraper 6 for cleaning the extrusion end of the pressure block 2 in the non-extrusion state when the placement platform 1 switches its state. During the angle switching process of the placement platform 1, the scraper 6 can be used to scrape off the tablet residues adhering to the extrusion end surface of the pressure block 2. Specifically, in order to optimize the scraping effect, the side surface of the placement platform 1 is provided with a mounting groove 7 for mounting the scraper 6; the scraper 6 is provided in multiple groups and arranged in the mounting groove 7 along the side extension direction; the length of each group of scrapers 6 accounts for about 1 / 7 to 1 / 5 of the mounting groove 7.

[0033] Each scraper 6 is installed in the installation groove 7 through an elastic member 8 (spring is sufficient), and the elastic member 8 makes the scraper 6 move in a telescopic manner along the opening direction of the installation groove 7 under pressure. On the one hand, the elastic member 8 applies pressure to the scraper 6 in the direction of squeezing the end surface of the pressure block 2 to optimize the scraping effect, and on the other hand, the scraper 6 can be stored in the installation groove 7 to ensure the normal operation of the angle switching of the placement platform 1 (without causing interference in the work).

[0034] Each scraper 6 has beveled edges 61 on both sides of the blade. The beveled edges 61 can be adjusted in accordance with the angle of the placement platform 1 , and the scraper 6 can be squeezed back into the installation slot 7 by the side wall of the frame 03 .

[0035] Preferably, an exhaust port 5 facing the discharge port 01 is provided on the side wall of the test space 00 of the present invention; after the placement platform 1 is reset after the discharge is completed, the exhaust port 5 releases a cleaning airflow, which can clean the tablet residues scraped off by the scraper 6 and the tablet residues remaining on the placement platform 1.

[0036] See also Figure 7, the exhaust port 5 is connected to an air supply component; the air supply component includes a pressurizing piston 81 arranged at the bottom of the placement platform 1, an elastic air storage component 82 (an elastic air bag made of rubber material can be used) connected to the pressurizing piston 81, and an air valve 83 installed at the exhaust port 5; the pressurizing piston 81 is a deformable bag-like structure (similarly, soft plastic or rubber material can be used), which is connected to the bottom surface of the placement platform 1 and the side wall of the frame 03 (forming a gas extrusion space of a predetermined volume); the elastic air storage component 82 is connected to the exhaust port 5.

[0037] In this embodiment, the air valve 83 is activated and closed by the change of the tilt angle of the placement platform 1 (an angle sensor is installed at the hinge of the placement platform 1, and the electronic control unit of the air valve 83 is controlled by the sensor to achieve this function). Specifically, when the placement platform 1 is flipped up to about 10° (specifically, the end away from the hinge edge is higher than the exhaust port 5), the air valve 83 opens. At this time, the inside of the pressurizing piston 81 is negative pressure, and the external air flow enters the pressurizing piston 81 or the elastic air storage member 82 from the exhaust port 5. The above working state can effectively prevent tablet residues from being sucked into the exhaust port 5.

[0038] When the placement platform 1 is turned up to the maximum angle, the air valve 83 enters a closed state;

[0039] When the discharge is completed and the placement platform 1 is restored to a horizontal state, the space inside the pressurizing piston 81 is pressurized, and the elastic air storage part 82 expands (the internal air pressure increases). When the placement platform 1 is restored to a horizontal state, the air valve 83 opens, and the air flow in the elastic air storage part 82 is released. In the above state, the air flow can be released instantly under the action of air pressure, thereby optimizing the cleaning effect.

[0040] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art may make various corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present invention.
