Description

Technical Field

[0001] The utility model relates to a particle measuring instrument, in particular to a toothpaste paste over-hard particles measuring instrument. Background Art

[0002] The abrasives in common toothpastes are all powder materials, and the commonly used ones are calcium carbonate, silicon dioxide, calcium phosphate, insoluble sodium metaphosphate, calcium pyrophosphate, etc. Their content in toothpaste is between 20%-60%. Therefore, for a high-quality toothpaste, it is particularly important to control the particle size of the abrasive powder material. Toothpaste made of abrasives with appropriate particle size has a smooth and delicate appearance and a comfortable feeling for the mouth and gums when brushing teeth. If the particle size is too small, the cleaning effect is not good, and if the particle size is too large, it will damage the tooth surface. Therefore, it is necessary to measure the hard particles of the toothpaste (hard particles refer to whether there are hard particles in the paste, and a hard particle analyzer is used for detection).

[0003] However, in the existing over-hard particle measuring instrument, the friction speed of the copper block is too fast and the pause time is too short during the measurement process, which will affect the friction of the copper block on the toothpaste, and then affect the measurement result of the over-hard particles of the paste. In view of this, it is necessary to design a new toothpaste paste over-hard particle measuring instrument to solve the above technical problems. Utility Model Content

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0018] The present utility model will be further described in detail below in conjunction with the drawings and specific embodiments.

[0020] By arranging the driving mechanism to drive the copper block to reciprocate in the sample measuring groove, the copper block presses and rubs the sample to be tested, so as to realize the measurement of hard particles.

[0021] In one embodiment, a positioning block 6 is provided between the support platform 3 and the driving mechanism 4 , a positioning rod 5 is transversely inserted into the positioning block 6 , one end of the positioning rod 5 is connected to the support platform, and the other end is connected to the driven rod.

[0022] A sliding groove 51 is formed on the surface of the positioning rod 5 , and a protrusion matched with the sliding groove is formed in the positioning block 6 , so that the positioning rod 5 can slide back and forth along the positioning block.

[0023] The positioning rod cooperates with the positioning block to ensure that the driving mechanism can drive the copper block to perform linear reciprocating motion, making the friction process more uniform and effective.

[0024] like Figure 2 As shown, the driving mechanism 4 includes a motor 41, a gear 42, and a connecting rod 43. The output end of the motor 41 is connected to a main shaft 44, and a wheel 45 linked to the gear 42 is sleeved on the main shaft 44. A driven shaft 48 is inserted in the center of the gear 42. One end of the driven shaft 48 is connected to the connecting rod 43, and the other end of the connecting rod 43 is rotatably connected to a driven rod 47.

[0025] Start the motor, the motor drives the main shaft to rotate, the rotation of the main shaft drives the wheel to rotate, the rotation of the wheel drives the gear meshing with it to rotate, the rotation of the gear drives the driven shaft connected to it to rotate, the rotation of the driven shaft drives the connecting rod to rotate, the rotation of the connecting rod pulls the driven rod to do reciprocating motion, the driven rod pulls the positioning rod to do linear motion, thereby driving the copper block to do reciprocating motion in the test slot, and the measurement of hard particles is achieved through the friction of the copper block.

[0026] Preferably, a gear tooth 46 is formed on half of the outer circumference of the wheel disc 45, and the wheel disc 45 is meshed with the gear 42 through the gear tooth 46. When the gear tooth contacts the gear, the connecting rod reciprocates, and when the gear is separated from the gear tooth, the gear stops rotating, so that the copper block stops. Through the above process, it is ensured that there is sufficient friction time between the copper block and the toothpaste paste during the friction process, thereby improving the friction of the copper block on the toothpaste, and then improving the measurement result of the hard particles in the paste.

[0027] In one embodiment, there are two copper blocks 2, which are symmetrically distributed with the positioning rod as the center.
