Abstract
Description
Technical Field
[0001] This utility model relates to the field of tablet hardness testing technology, specifically a tablet hardness testing device. Background Technology
[0002] The hardness of tablets generally refers to their compressive strength, that is, the radial crushing force of the tablet. Sufficient hardness can prevent tablets from breaking or being worn during packaging, transportation, etc., thus ensuring the accuracy of dosage. The YPD-200C tablet hardness tester is one of the devices used to test the hardness of tablets.
[0003] Existing hardness testers require manual cleaning of tablet fragments generated during previous tests to avoid affecting subsequent tablet testing, causing inconvenience to users. Therefore, a tablet hardness testing device is proposed to solve the above problems. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides a tablet hardness testing device with advantages such as automatic tablet fragment cleaning. This solves the problem that existing hardness testers require manual cleaning of previously generated tablet fragments to avoid affecting subsequent tablet tests, which causes inconvenience to users.

[0006] Furthermore, the cleaning mechanism includes columns, a movable plate, a telescopic spring, a pressing rod, rollers, a mounting plate, and a brush. Two columns are fixedly installed on the left end of the rear side of the inner wall of the groove. The movable plate is movably sleeved on the outer peripheral wall of the columns. A telescopic spring is sleeved on the rear end of the outer peripheral wall of the columns. The pressing rod is fixedly installed on the center of the front of the movable plate. The rollers are located on the front of the movable plate. The mounting plate is fixedly installed on the right side of the movable plate. The brush is detachably installed on the front of the mounting plate.
[0007] Furthermore, L-shaped fixing blocks are provided on the front of the mounting plate and on both the left and right sides of the brush. Snap-fit grooves are provided on both the left and right sides of the brush. A snap-fit block with one end extending into the snap-fit groove is fixedly installed on the opposite side of each of the two L-shaped fixing blocks. The L-shaped fixing blocks are fixedly connected to the mounting plate by fixing screws.
[0008] Furthermore, an arc-shaped groove is provided on the right side of the back of the extrusion plate, and the arc-shaped groove matches the roller.
[0009] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0010] 1. This tablet hardness testing device, through its cleaning mechanism, can automatically sweep the tablet fragments remaining on the test plate into the collection box during tablet testing, thus achieving the purpose of automatically cleaning tablet fragments.
[0011] 2. This tablet hardness testing device, with its L-shaped fixing block and fixing screws, facilitates quick brush replacement for users, enhancing the device's practicality. Attached Figure Description

Detailed Implementation
[0017] 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 protection scope of the present utility model.
[0018] Please see Figure 1-4The tablet hardness testing device in this embodiment includes a hardness tester body 1. A groove 2 is provided at the top center of the hardness tester body 1. A collection box 3 is placed on the inner bottom wall of the groove 2. A squeezing plate 4 is provided inside the hardness tester body 1, with one end extending to the left end of the groove 2. A detection plate 5 is provided inside the hardness tester body 1, with one end extending to the right end of the groove 2. A cleaning mechanism 6 is provided on the rear side of the groove 2.
[0019] In this embodiment, the cleaning mechanism 6 includes a column 61, a movable plate 62, a telescopic spring 63, a pressing rod 64, a roller 65, a mounting plate 66, and a brush 67. Two columns 61 are fixedly installed on the left end of the rear side of the inner wall of the groove 2. The movable plate 62 is movably sleeved on the outer peripheral wall of the column 61. The telescopic spring 63 is sleeved on the rear end of the outer peripheral wall of the column 61. The pressing rod 64 is fixedly installed on the center of the front of the movable plate 62. The roller 65 is located on the front of the movable plate 62. The mounting plate 66 is fixedly installed on the right side of the movable plate 62. The brush 67 is detachably installed on the front of the mounting plate 66.
[0020] An arc-shaped groove 41 is provided on the right side of the back of the extrusion plate 4, and the arc-shaped groove 41 matches the roller 65.
[0021] Specifically, when the extrusion plate 4 moves to the right to perform the tablet extrusion test, the roller 65 rolls on the side of the extrusion plate 4, keeping the pressing rod 64 pressing the movable plate 62. At this time, the telescopic spring 63 is in a compressed, energy-storing state. After the tablet test is completed, when the extrusion plate 4 moves to the leftmost position, the roller 65 will enter the arc-shaped groove 41. At this time, the telescopic spring 63 resets and moves the brush 67 forward to sweep the tablet fragments remaining on the detection plate 5 into the collection box 3. In this way, the purpose of automatically cleaning tablet fragments is achieved. In addition, after cleaning, as the extrusion plate 4 moves to the right a certain distance, the brush 67 can retract backward, and the testing personnel can place the tablets.
[0022] In this embodiment, L-shaped fixing blocks 661 are provided on the front of the mounting plate 66 and on both the left and right sides of the brush 67. The left and right sides of the brush 67 are provided with snap-fit grooves 671. A snap-fit block 662 with one end extending into the snap-fit groove 671 is fixedly installed on the opposite side of the two L-shaped fixing blocks 661. The L-shaped fixing blocks 661 are fixedly connected to the mounting plate 66 by fixing screws 663.
[0023] Specifically, loosen the fixing screw 663, pull out the L-shaped fixing block 661, and disengage the snap-fit block 662 from the snap-fit groove 671 to remove the brush 67; insert the snap-fit block 662 into the snap-fit groove 671 of the new brush 67, press the new brush 67 against the mounting plate 66, and tighten the fixing screw 663 to complete the installation of the new brush 67. This facilitates quick replacement of the brush 67 for the user.
