Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a fixture structure for a vacuum planetary gravity mixer. Background Art

[0002] Vacuum planetary gravity mixers are mainly applied to the field of mixing and stirring of materials for products in high-tech, sophisticated fields such as LED, LCD, medical devices, electronic components, electronic packaging materials, and new energy materials. They can solve problems that cannot be solved by traditional mixing equipment, enabling different components of slurries and powders to be fully and evenly mixed, without stratification, no bubbles, and higher efficiency.

[0003] After the sample to be stirred is placed in the sample receptacle, the sample receptacle is clamped into the equipment slot, and the equipment control room door is closed for vacuum stirring and defoaming. Currently, the sample receptacle can usually only hold one sample. The sample receptacle is of a general specification and cannot meet the fitting use of samples of different specifications, with a small application range. During the high-speed operation of the equipment, relative movement is likely to occur between the sample and the sample receptacle, affecting the mixing effect. Moreover, during the mixing process, the sample receptacle will continuously heat up and cannot dissipate heat in a timely and effective manner, easily increasing the loss of equipment accessories and the maintenance cost. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a fixture structure for a vacuum planetary gravity mixer, aiming to solve the technical problems in the prior art that the sample receptacle has few sample placements, a small application range, the sample is prone to move after being placed, affecting the mixing effect, and the sample receptacle will also heat up during the mixing process and cannot dissipate heat, increasing the loss and maintenance cost.

[0005] The technical solution of the utility model is: a fixture structure for a vacuum planetary gravity mixer, including a fixture body. A plurality of sample placement slots are provided on the fixture body. At the notch of each sample placement slot, a plurality of first positioning elastic pieces for clamping the sample in cooperation are provided. The first positioning elastic pieces are inclined towards the center of the sample placement slot, and positioning convex points are provided on the inner side of the first positioning elastic pieces. On one side of each sample placement slot, a second positioning elastic piece is respectively provided. The second positioning elastic piece is telescopically installed in the fixture body. The second positioning elastic piece includes an externally convex deforming part and an internally pressing deforming part connected in series. When the externally convex deforming part is compressed inward by force, it can drive the internally pressing deforming part to extend into the sample placement slot to press the sample tightly. A plurality of heat dissipation holes communicating with the sample placement slots are also provided on the fixture body.

[0006] Further, in the utility model, there are three sample placement slots, which are arranged at equal angles around the central axis of the fixture body.

[0007] Further, in the utility model, two of the first positioning elastic pieces are symmetrically provided at the notch of each sample placement slot.

[0008] Furthermore, a rubber pad is provided at the bottom of the sample placement groove in the present utility model.

[0009] Furthermore, an expansion space for the second positioning elastic piece to expand and contract is provided inside the fixture body in the present utility model. The expansion space communicates with the outside of the fixture body and the corresponding sample placement groove, and at least a part of the outward convex deformation part is located outside the expansion space.

[0010] Furthermore, the heat dissipation holes in the present utility model are divided into three groups and are respectively provided corresponding to each sample placement groove.

[0011] Compared with the prior art, the present utility model has the following advantages: When the fixture of the present utility model is used, three samples can be placed simultaneously. After the samples are placed in the sample placement grooves, they can be initially clamped and fixed by the first positioning elastic pieces. When the fixture together with the samples is placed into the device, the second positioning elastic pieces will further lock the samples due to being squeezed, ensuring that there is no relative movement between the samples and the fixture. The fixture of the present utility model can be applicable to samples of different specifications. The setting of the heat dissipation holes can also quickly dissipate the heat generated by stirring, reduce the loss of equipment accessories, and lower the maintenance cost.

[0015] The following specifically describes the detailed embodiments of the present utility model with reference to the drawings.

[0016] Embodiment:

[0017] As shown in the drawings, a detailed embodiment of a fixture structure for a vacuum planetary gravity mixer in the present utility model mainly includes a fixture body 1. Three sample placement grooves 2 are provided on the fixture body 1, and the three sample placement grooves 2 are arranged at equal angles around the central axis of the fixture body 1.

[0018] At the notch of each sample placement groove 2, two first positioning elastic pieces 3 for cooperatively clamping the samples are provided, and the two first positioning elastic pieces 3 are symmetrically arranged. Each first positioning elastic piece 3 is inclined towards the center of the sample placement groove 2, and a positioning convex point 3a is further provided on the inner side of the first positioning elastic piece 3, which can better clamp and fix the samples.

[0019] A rubber pad 4 is provided at the bottom of each sample placement groove 2, which can increase the friction with the sample.

[0020] On one side of each sample placement groove 2, a second positioning elastic piece 5 is respectively provided. The second positioning elastic piece 5 is telescopically installed in the fixture body 1. Specifically, a telescopic space for the second positioning elastic piece 5 to expand and contract is provided inside the fixture body 1. The telescopic space communicates with the outside of the fixture body 1 and the corresponding sample placement groove 2. The second positioning elastic piece 5 includes an externally convex deformed part 5a and an internally pressed deformed part 5b that are connected. The externally convex deformed part 5a is at least partially located outside the telescopic space. As Figure 1 shown, when the externally convex deformed part 5a is forced to compress inward, it can drive the internally pressed deformed part 5b to extend into the sample placement groove 2 to tightly press the sample.

[0021] In this embodiment, a plurality of heat dissipation holes 6 communicating with the sample placement groove 2 are further provided on the fixture body 1. The heat dissipation holes 6 are divided into three groups and are respectively arranged corresponding to each sample placement groove 2.

[0022] When the fixture of the present utility model is used, three samples can be placed at the same time. After the samples are placed in the sample placement grooves 2, they can be initially clamped and fixed by two first positioning elastic pieces 3. When the fixture together with the samples is placed into the equipment as a whole, the second positioning elastic piece 5 will further lock the samples due to being squeezed, ensuring that there is no relative movement between the samples and the fixture. The fixture of the present utility model can be applicable to samples of different specifications. The arrangement of the heat dissipation holes 6 can also quickly dissipate the heat generated by stirring, reduce the loss of equipment accessories, and lower the maintenance cost.
