Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, and in particular to an adjustable small-size sample preparation tool. Background Technology

[0002] In the field of plastic flammability testing, oxygen index testing is an important and commonly used method. By determining the minimum oxygen concentration required for plastics to sustain combustion in an oxygen-nitrogen mixture, the ease with which plastics can burn can be accurately assessed, providing crucial information for safety assessment, product design, and quality control of plastic materials.

[0003] When preparing plastic samples for oxygen index testing, specific tools are needed to precisely cut the plastic material. Common preparation tools are usually equipped with two saw blades. However, adjusting the saw blade spacing is extremely troublesome. In actual testing, due to the thickness of different types of plastic materials and the diversity of testing standards, it is often necessary to frequently and precisely adjust the saw blade spacing. However, the existing adjustment mechanism is complex in design and cumbersome in operation. It usually requires the use of a variety of additional auxiliary tools, which consumes a lot of time and manpower and seriously affects work efficiency.

[0004] Furthermore, adjusting the width and height of the tool is equally difficult. For plastic materials of different sizes and shapes, the width and height of the tool need to be adjusted accordingly to ensure the accuracy and effectiveness of the cut. However, the existing tools do not have flexible adjustment structures in this regard, the adjustment range is limited, and it is difficult to guarantee accuracy during the adjustment process. This not only leads to inconsistent sample quality that fails to meet strict testing standards, but may also result in material waste and increased testing costs due to repeated adjustments.

[0005] To address this issue, an adjustable small-scale sample preparation tool is proposed to solve the problems existing in the prior art. Utility Model Content

[0006] The purpose of this utility model is to address the aforementioned problems by providing an adjustable small-scale sample preparation tool. This utility model uses a lifting assembly to move the entire rotating cylinder downwards, causing the two saw blades to disengage from their current working slots. An adjustment assembly then adjusts the two saw blades. After the two saw blades move to the lower end of the designated working slot, the lifting assembly raises them, allowing them to stably enter the corresponding working slot. This improves stability, simplifies the adjustment process, reduces manual intervention, and increases work efficiency. To achieve the above-mentioned utility model objectives, the technical solution adopted is as follows:

[0007] According to one aspect of this utility model, an adjustable small-size sample preparation tool is provided, including a worktable, a guide plate on the worktable, and multiple working slots symmetrically opened on the worktable, the multiple working slots being arranged in pairs and sequentially. A drive motor is provided at the bottom of the worktable, and a rotating cylinder is provided at the output end of the drive motor. A limiting plate is symmetrically provided on the circumference of the rotating cylinder. Two movable seats are provided on the rotating cylinder, and a saw blade is provided on each movable seat. Each saw blade is located in a working slot. A support rod is provided on the side of the rotating cylinder away from the drive motor, and the other end of the support rod is connected to the bottom of the worktable. The support rod is a telescopic rod. An adjustment component for adjusting the distance between the two saw blades is provided at the bottom of the worktable, and a lifting component for adjusting the height of the saw blades is provided at the bottom of the worktable.

[0008] Preferably, the adjustment assembly includes a cylinder disposed at the bottom of the worktable, a connecting plate disposed at the output end of the cylinder, two ball bearing seats symmetrically disposed on the connecting plate, each ball bearing seat being provided with an active ball bearing, each movable seat being provided with an annular limiting groove, each limiting groove being provided with a driven ball bearing, and a connecting rod being provided between each active ball bearing and the driven ball bearing.

[0009] Preferably, the lifting assembly includes two hydraulic telescopic rods symmetrically arranged at the bottom of the workbench, and two limiting rings symmetrically arranged at both ends of the rotating drum, with each hydraulic telescopic rod connected to a corresponding limiting ring.

[0010] Preferably, two symmetrical sliding grooves are provided on the worktable, and multiple slots are provided in each sliding groove near the guide plate. Two locking blocks are symmetrically provided at the lower end of the guide plate.

[0011] Preferably, each of the slides has the same number of slots on the side away from the guide plate.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0013] The adjustable small-size sample preparation tool of this utility model uses a lifting component to move the entire rotating cylinder downwards, causing the two saw blades to disengage from the current two working slots.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of the utility model, and these aspects can be achieved even without these specific details.

[0020] Please see Figures 1 to 4 This utility model provides an adjustable small-size sample preparation tool, the technical solution of which is as follows:

[0021] The device includes a workbench 1, on which a guide plate 2 is provided. The guide plate 2 can guide and position the plastic material, making the cutting more accurate and standardized, which helps to improve the consistency and pass rate of samples and reduce the impact of human factors on the cutting effect. Multiple working slots 3 are symmetrically opened on the workbench 1, and the multiple working slots 3 are arranged in pairs. A drive motor 4 is provided at the bottom of the workbench 1. A rotating cylinder 5 is provided at the output end of the drive motor 4. A limiting plate 6 is symmetrically provided on the circumference of the rotating cylinder 5. Two movable seats 7 are provided on the rotating cylinder 5, and a saw blade 8 is provided on each movable seat 7. Each saw blade 8 is located in a working slot 3. A support rod 9 is provided on the side of the rotating cylinder 5 away from the drive motor 4, and the other end of the support rod 9 is connected to the bottom of the workbench 1. The support rod 9 is a telescopic rod. An adjustment component for adjusting the distance between the two saw blades 8 is provided at the bottom of the workbench 1, and a lifting component for adjusting the height of the saw blades 8 is provided at the bottom of the workbench 1.

[0022] Multiple working slots 3 are arranged in pairs, and the multiple working slots 3 are arranged symmetrically in sequence. When cutting existing small-sized samples, the spacing between two saw blades 8 is generally set to 10mm, 13mm and 25.4mm. The multiple working slots 3 are arranged in pairs according to the spacing data. The lifting component drives the entire rotating drum 5 to move downward, so that the two saw blades 8 are separated from the current two working slots 3. Then the adjustment component adjusts the two saw blades 8. After the two saw blades 8 move to the lower end of the designated working slot 3, the lifting component drives the two saw blades 8 to rise. The two saw blades 8 can stably enter the corresponding working slot 3, which improves stability, simplifies the adjustment process, reduces manual intervention and improves work efficiency.

[0023] The drive motor 4 can drive the two saw blades 8 to rotate through the rotating drum 5, and the adjustment component can adjust the distance between the two saw blades 8 laterally. The limiting plate 6 is set to restrict the moving seat 7 corresponding to the saw blade 8. When the adjustment component adjusts the saw blade 8, the saw blade 8 will not rotate, thus ensuring the stability of the adjustment.

[0024] The adjustment assembly includes a cylinder 10 disposed at the bottom of the workbench 1. A connecting plate 11 is provided on the output end of the cylinder 10. Two ball bearing seats 12 are symmetrically disposed on the connecting plate 11, and each ball bearing seat 12 is provided with an active ball bearing 13. Each movable seat 7 is provided with an annular limiting groove 14, and each limiting groove 14 is provided with a driven ball bearing 15. A connecting rod 16 is provided between each active ball bearing 13 and the driven ball bearing 15.

[0025] When adjustment is needed, the lifting assembly moves the entire roller downwards, causing the two saw blades 8 to disengage from the current working slot 3. Then, the cylinder 10 is activated, driving the connecting plate 11 to move back and forth. Through the cooperation of the active ball bearing 13, the driven ball bearing 15, and the connecting rod 16, the linear motion of the cylinder 10 is precisely converted into the lateral displacement of the moving seat 7, thereby achieving the adjustment of the saw blade spacing. The annular limiting groove 14 and the driven ball bearing 15 on the moving seat 7, together with the limiting plate 6, restrict the movement trajectory of the moving seat 7, ensuring that it can only move in a specific direction, and also enhancing the structural stability of the entire adjustment assembly. Compared with traditional tools, this method does not require complicated manual operation, can quickly adapt to the cutting needs of different plastic materials, and improves work efficiency.

[0026] The lifting assembly includes two hydraulic telescopic rods 17 symmetrically arranged at the bottom of the workbench 1. Two limiting rings 18 are symmetrically arranged at both ends of the rotating drum 5, and each hydraulic telescopic rod 17 is connected to the corresponding limiting ring 18. The hydraulic telescopic rods 17 can provide stable and precise telescopic power. By controlling the inlet and outlet of hydraulic oil, the height of the saw blade 8 can be precisely adjusted. Compared with some traditional manual or other methods of height adjustment, the hydraulic telescopic rods 17 can achieve more delicate and accurate height control, ensuring that the saw blade 8 is in the optimal cutting position, thereby improving the cutting accuracy and quality.

[0027] The worktable 1 has two symmetrically arranged slides 19, and each slide 19 has multiple slots 20 near the guide plate 2. The guide plate 2 has two symmetrically arranged blocks 21 at its lower end. The slide 19 design on the worktable 1 allows the guide plate 2 to move along the slide 19, and the position of the guide plate 2 can be adjusted according to the size of different plastic materials and cutting requirements. At the same time, the multiple slots 20 near the guide plate 2 in the slide 19, together with the blocks 21 at the lower end of the guide plate 2, can fix the guide plate 2 in a suitable position, provide precise guidance for the plastic material, and improve the accuracy and consistency of cutting.

[0028] Each of the slide grooves 19 has the same number of slots 20 on the side away from the guide plate 2; the adjustable position of the guide plate 2 is increased so that the feed direction can be changed. In some special cases, such as when reverse feed is required, it can be moved to the other side for feed cutting, realizing diversified cutting path planning and meeting more complex cutting needs.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
