Description

Technical Field

[0001] This utility model relates to the field of mixing instruments, and more particularly to sample mixing equipment. Background Technology

[0002] In the medical field, to facilitate drug preparation and sample testing, it is usually necessary to seal at least two samples in a container and use a mixer to mix the at least two samples in the container.

[0003] Most current mixers use a rolling method for mixing, placing the container between two rolling rollers. The friction between the rollers and the container causes the container to roll, thus tumbling and mixing the sample. This type of mixer has a simple motion mode and limited application scenarios. Due to its relatively low impact, it is mostly used for mixing samples requiring flexible mixing, such as viscous liquids and liquid-solid suspensions. However, when mixing other samples, such as viscous gels, the time required is relatively long, and incomplete mixing is prone to occur, resulting in low mixing efficiency and poor mixing effect.

[0024] The sample mixing device further includes a vibration mixing mechanism 20, which includes a vibration mixing disk 21 and at least one vertical vibration component 22. The vibration mixing disk 21 is positioned above the vertical vibration component 22 and is driven by the vertical vibration component 22 to vibrate vertically. The tumbling mixing mechanism 10 is mounted on the vibration mixing disk 21 and is driven by the vibration mixing disk 21 to move synchronously, so as to vertically vibrate at least two samples mounted in the container of the rotating component 11, so as to cooperate with the tumbling mixing mechanism 10 to further mix at least two samples, so as to be suitable for samples of different forms, improve the degree of mixing, thereby speeding up the mixing speed and improving the mixing efficiency.

[0025] Preferably, the vertical vibration component 22 is implemented as an electric cylinder or a hydraulic cylinder.

[0026] It is worth mentioning that after one of the at least two samples in the container is made into a liquid and homogenized, the vibrating mixing disk 21 is driven by the vertical vibration component 22 to continuously vibrate vertically to vibrate and remove bubbles from the homogenized sample in the container.

[0027] refer to Figures 2 to 3 The rotating component 11 includes at least two rotating rollers 111, which are rotatable. The at least two rotating rollers 111 are spaced apart in an axially parallel manner, and the distance between at least some adjacent rotating rollers 111 is less than the radial dimension of the container.

The two rotating rollers 111 carrying the same container rotate in the same direction, and the container is driven to rotate in the same direction by the corresponding rotating rollers 111 to tumble and stir at least two samples inside.

[0028] Preferably, at least two containers are arranged in a direction parallel to the axial direction of the belt rollers 111 between two adjacent belt rollers 111 with a spacing smaller than the radial dimension of the container, so as to achieve simultaneous mixing of at least two samples in multiple containers and improve work efficiency.

[0029] Preferably, multiple rotating rollers 111 are provided, and all rotating rollers 111 rotate in the same direction. The distance between any two adjacent rotating rollers 111 is less than the radial dimension of the container. At least one container is placed between any two adjacent rotating rollers 111, and the corresponding container rotates in the same direction to tumble and stir at least two samples inside. In this way, two adjacent containers located in the arrangement direction of the multiple rotating rollers 111 are supported by the same rotating roller 111, so as to support more containers while minimizing the number of rotating rollers 111, meeting the needs of batch operation.

[0030] In another embodiment, multiple rotating rollers 111 are provided, with each pair of rotating rollers 111 forming a group. The two rotating rollers 111 in each group rotate in the same direction, and the distance between the two rotating rollers 111 in each group is less than the radial dimension of the container.

Each pair of adjacent sprockets simultaneously meshes with one chain. One sprocket is mounted on and driven to rotate by the drive member 121, so that when the corresponding sprocket is driven to rotate by the drive member 121, the remaining sprockets are driven to rotate synchronously through the meshing action of the chain and the sprocket, thereby causing all rotating rollers 111 to rotate in the same direction.

[0034] In another embodiment, when multiple rotating rollers 111 are provided, with each pair of rotating rollers 111 forming a group, and the rotation directions of the two rotating rollers 111 in each group being the same, the transmission assembly 122 is implemented to include multiple first gears and multiple groups of second gears. The number of groups of second gears is the same as the number of groups of rotating rollers 111, and each group of second gears has two gears. Each second gear is coaxially connected to one rotating roller 111. The number of first gears is the same as the number of groups of second gears. Each first gear meshes with two second gears in a group, and the two closest second gears in adjacent groups mesh with each other. One of the second gears is mounted on the drive member 121 and driven to rotate by the drive member 121. The second gear driven to rotate by the drive member 121 drives the first gear meshing with it to rotate, and through the corresponding first gear, drives another second gear in the same group to rotate in the same direction. By utilizing the meshing action of the two closest second gears in adjacent groups, all the second gears rotate, thereby causing all the rotating rollers 111 to rotate.

Each motor is mounted on one of the rotating rollers 111, and the rotating rollers 111 are driven to rotate by the motors.

[0036] It is worth mentioning that the rotation speed of the drive component 121 is adjustable to adjust the rotation speed of the belt roller 111, thereby adjusting the tumbling speed of at least two samples in the container, so as to select according to the properties and formulation of the samples, so as to avoid the rotation speed being too fast or too slow and affecting the mixing uniformity and mixing efficiency.

[0037] In addition, the operating time of the drive component 121 is adjustable to adjust the rotation duration of the belt roller 111, thereby adjusting the tumbling duration of at least two samples in the container, so as to select according to the properties and formula of the samples, so as to avoid the running time being too long or too short and affecting the mixing effect.

[0038] refer to Figures 1 to 3The vibrating mixing disk 21 includes a disk body 211 and multiple connecting members 212. The sample mixing device also includes a mounting platform 30, which includes a disk body 31 and multiple connecting members 32. Multiple vertical vibration components 22 are provided, and these components are arranged adjacent to each other at a predetermined distance below the vibrating mixing disk 21. Each vertical vibration component 22 has a connecting member 212 and a connecting member 32 installed at both ends. Each vertical vibration component 22 is rotatably connected to the disk body 211 and the platform 31 via the connecting member 212 and the connecting member 32, respectively. The vertical vibration component 22 is configured to drive the disk body 211 to vibrate vertically via the corresponding connecting member 212.

[0039] The vibration mixing mechanism 20 further includes a horizontal swaying member 23, which includes at least one transverse swaying component 231. At least one connecting member 212 is disposed on the side of the disk body 211. Each transverse swaying component 231 is rotatably connected to the disk body 211 via the connecting member 212 disposed on the side of the disk body 211. One end of the transverse swaying component 231 away from the corresponding connecting member 212 is rotatably connected to the platform 31 via a connecting member 32. The transverse swaying component 231 is configured to drive the disk body 211 to sway laterally via the corresponding connecting member 212. At the same time, the vertical vibration component 22 is subjected to the force transmitted by the vibration mixing disk 21 and swings in the same direction, so that the vertical vibration component 22 can support the vibration mixing disk 21 while accommodating its transverse swaying. In this way, under the combined action of the vertical vibration component 22 and the horizontal shaking component 231, the vibrating mixing disk 21 vibrates vertically and shakes horizontally at the same time. Based on the tumbling mixing mechanism 10 driving the container to rotate axially to mix materials, the mixing method is multi-faceted and arbitrarily selectable, that is, any one or a combination of tumbling mixing method, vertical vibration mixing method and horizontal shaking mixing method can be selected, increasing the diversity of uniformity methods and ensuring the mixing effect and mixing efficiency.

[0040] Preferably, there are two lateral swaying components 231, which are spaced apart on the same side, so that the disc body 211 can sway stably in the lateral direction when the lateral swaying components 231 are running.

[0041] Preferably, the lateral swaying component 231 is implemented as an electric cylinder or a hydraulic cylinder.

[0042] It is worth mentioning that the operation of the lateral shaking component 231 is adjustable to adjust the shaking frequency of the disc 211 in the lateral direction, thereby adjusting the shaking speed of at least two samples in the container in the lateral direction, so as to select according to the properties and formulation of the samples, so as to avoid the mixing uniformity and mixing efficiency being affected by the rotation speed being too fast or too slow.

[0043] In addition, the operating time of the lateral shaking component 231 is adjustable to adjust the lateral shaking duration of the disc 211, thereby adjusting the lateral shaking duration of at least two samples in the container, so as to select according to the properties and formula of the samples, so as to avoid the mixing effect being affected by the running time being too long or too short.

[0044] Furthermore, the horizontal swaying component 23 also includes at least one longitudinal swaying component 232, which and the transverse swaying component 231 are respectively located on adjacent sides of the disk body 211. Each end of the longitudinal swaying component 232 is respectively equipped with a connecting member 212 and a connecting member 32, and each longitudinal swaying component 232 is rotatably connected to the disk body 211 and the platform 31 via the connecting member 212 and the connecting member 32. The longitudinal swaying component 232 is configured to drive the disk body 211 to sway longitudinally via the corresponding connecting member 212, while the vertical vibration component 22 and the transverse swaying component 231 oscillate in the same direction due to the force transmitted by the vibrating mixing disk 21. In this way, under the combined action of the vertical vibration component 22, the horizontal shaking component 231, and the longitudinal shaking component 232, the vibrating mixing disk 21 vibrates vertically and shakes horizontally at the same time. Based on the tumbling mixing mechanism 10, the container is driven to rotate axially to mix materials, so that there are multiple and arbitrary mixing methods, that is, any one or a combination of tumbling mixing method, vertical vibration mixing method, horizontal shaking mixing method, and longitudinal shaking mixing method can be selected, which increases the diversity of uniformity methods and ensures the mixing effect and mixing efficiency.

[0045] Preferably, there are two longitudinal shaking components 232, which are spaced apart on the same side, so that the disc body 211 can shake stably in the longitudinal direction when the longitudinal shaking components 232 are running.

[0046] Preferably, the longitudinal swaying component 232 is implemented as an electric cylinder or a hydraulic cylinder.

[0047] It is worth mentioning that the operation of the longitudinal shaking component 232 is adjustable to adjust the shaking frequency of the disc 211 in the longitudinal direction, thereby adjusting the shaking speed of at least two samples in the container in the longitudinal direction, so as to select according to the properties and formulation of the samples, so as to avoid the mixing uniformity and mixing efficiency being affected by the rotation speed being too fast or too slow.

[0048] In addition, the operating time of the longitudinal shaking component 232 is adjustable to adjust the shaking duration of the disc 211 in the longitudinal direction, thereby adjusting the shaking duration of at least two samples in the container in the longitudinal direction, so as to select according to the properties and formula of the samples, so as to avoid the mixing effect being affected by the running time being too long or too short.

[0049] Preferably, the connecting member 212 is implemented as a ball cage universal joint, and the connecting member 32 is implemented as a cross shaft universal joint, so that the vertical vibration assembly 22 connected to the connecting member 32 can provide stable support for the disc 211.

[0050] refer to Figures 1 to 2 The sample mixing device also includes a protective cover 40, which is installed above the vibrating mixing disc 21. The protective cover 40 is configured to cover the rotating component 11 to limit the container placed on the rotating component 11, so as to prevent the container from detaching from the rotating component 11 when it vibrates vertically, and to ensure that the mixing operation can be carried out normally.

[0051] Preferably, the protective cover 40 is rotatably mounted on the vibrating mixing disc 21, and the protective cover 40 is configured to rotate away from or away from the surface of the rotating member 11, so as to ensure that the container can be kept above the rotating member 11 during mixing while the container is being picked up and put down.
