Description

Technical Field

[0001] This utility model relates to the field of pressing equipment technology, specifically a sample pressing machine. Background Technology

[0002] In many fields, such as steel, cement, pharmaceutical testing, commodity inspection, coal, geology and mining, scientific research, and environmental monitoring, the chemical composition analysis of non-metallic solid materials is a common requirement. The general process involves first grinding these materials into extremely fine powder using grinding equipment, then pressing the powder into samples using a sample press, and finally using X-ray fluorescence spectrometry or energy dispersive spectroscopy for rapid chemical composition analysis. However, existing sample presses have several drawbacks.

[0003] Based on the above, the inventors have discovered the following problem: the current sample pressing machine does not have a quick centering clamping function for the sample cylinder, resulting in low sample pressing efficiency and affecting user experience.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings to provide a pressing machine with greater practical value. Utility Model Content

[0005] The purpose of this utility model is to provide a sample pressing machine to solve the problem mentioned in the background art that the current sample pressing machine does not have a quick centering and clamping function for the sample cylinder, resulting in low sample pressing efficiency and affecting the user's use.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A sample pressing machine includes a base box, a sample pressing cylinder at the top center of the base box, clamping blocks for holding the sample pressing cylinder on both sides of the top of the base box, an adjusting mechanism for adjusting the distance between the pair of clamping blocks inside the base box, a column mounted on one side of the base box, a cross arm mounted on the top of the column, a fixed plate mounted on one end of the cross arm, a hydraulic rod mounted on the top of the fixed plate, the output end of the hydraulic rod penetrating the bottom end of the fixed plate, a lifting plate mounted on the bottom end of the fixed plate, a connecting sleeve mounted on the bottom end of the lifting plate, a connecting seat inserted inside the connecting sleeve, a pressure plate mounted on the bottom end of the connecting seat, a slot formed on the outer side of the connecting seat, a locking bolt mounted on one side of the connecting sleeve, one end of the locking bolt engaging with the inner side of the slot, and a pair of sliding rods slidably connected inside the fixed plate, the bottom ends of the sliding rods being fixedly connected to the top of the lifting plate.

[0008] Furthermore, the adjusting mechanism includes a bidirectional threaded rod, the two ends of which are rotatably connected to the inner sides of the base box. Each end of the bidirectional threaded rod is fitted with a slide, and one side of each pair of slides is fixedly connected to one side of each pair of clamping blocks. A motor is installed on one end face of the base box, and the output end of the motor is connected to one end of the bidirectional threaded rod.

[0009] The beneficial effect of adopting the above-mentioned further solution is that, through the arrangement of the bidirectional threaded rod, the slide, and the motor, the motor drives the bidirectional threaded rod to rotate, and the opposite thread structure at both ends of the bidirectional threaded rod drives the two slides to move synchronously towards or away from each other, thereby adjusting the spacing between the clamping blocks.

[0010] Furthermore, the top two sides of the base box are provided with sliding grooves, and the inner side of the sliding grooves is slidably connected to the outer side of the slide frame.

[0011] The advantage of adopting the above-mentioned further solution is that the sliding connection between the inner side of the slide groove and the outer side of the slide improves the movement stability of the slide.

[0012] Furthermore, V-shaped grooves are provided on adjacent sides of each pair of clamping blocks.

[0013] The beneficial effect of adopting the above-mentioned further solution is that by opening V-shaped grooves on the adjacent sides of a pair of clamping blocks, it can be fitted with the outer cylindrical surface of the sample pressing cylinder. By utilizing the automatic centering characteristics of the V-shaped structure, the sample pressing cylinder can be positioned quickly and accurately, ensuring that it is in the center position.

[0014] Furthermore, a reinforcing block is installed at the top of one side of the column, and the top of the reinforcing block is fixedly connected to the bottom of the cross arm.

[0015] The beneficial effect of adopting the above-mentioned further solution is that by installing a reinforcing block at the top of one side of the column, the structural strength and rigidity of the connection between the column and the crossarm are significantly enhanced.

[0016] Furthermore, support bases are installed at the four corners of the bottom of the base box, and the bottom of the support bases is provided with anti-slip texture.

[0017] The advantage of adopting the above-mentioned further solution is that the placement stability of the device is improved by installing support bases at all four corners of the bottom of the base box.

[0018] Furthermore, a control panel is installed on the other side of the base box.

[0019] The advantage of adopting the above-mentioned further solution is that the control panel installed on the other side of the base box enables the equipment to be controlled, increasing the ease of use of the product.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: This sample pressing machine, through the setting of the sample pressing cylinder, is used to place the sample to be pressed. The clamping blocks on both sides can be adjusted in distance by the action of the adjusting mechanism to adapt to different specifications of sample pressing cylinders, ensuring their stable fixation and preventing shaking during sample pressing. The column, cross arm and fixed plate form a cantilever support structure. The hydraulic rod is installed on the fixed plate and can drive the lifting plate to slide up and down along the slide rod, driving the connecting sleeve, connecting seat and pressure plate to press the sample in the sample pressing cylinder. The connecting seat and connecting sleeve are engaged by locking bolts and slots, which facilitates the disassembly and replacement of the pressure plate to meet different sample pressing needs. Through the setting of bidirectional threaded rod, slide and motor, the motor drives the bidirectional threaded rod to rotate. The opposite thread structure at both ends of the bidirectional threaded rod drives the two slides to move synchronously towards each other. The clamping blocks can be moved in opposite directions to adjust the spacing between them. The sliding connection between the inner side of the slide groove and the outer side of the slide frame improves the stability of the slide frame's movement. V-shaped grooves are provided on adjacent sides of each pair of clamping blocks to achieve contact with the outer cylindrical surface of the sample cylinder. Utilizing the automatic centering characteristic of the V-shaped structure, the sample cylinder can be quickly and accurately positioned, ensuring it is centered. A reinforcing block is installed at the top of one side of the column, significantly enhancing the structural strength and rigidity of the connection between the column and the crossarm. Support seats are installed at the four corners of the bottom of the base box to improve the stability of the device. A control panel is installed on the other side of the base box, enabling controllable equipment and increasing ease of use. This invention effectively achieves rapid centering and clamping of the sample cylinder, improving sample pressing efficiency and possessing high practical value. Attached Figure Description
