Description

Technical Field

[0001] This utility model relates to the field of hot pressing of plastic granules, and more particularly to a hot pressing device for plastic granules used for infrared analysis and X-ray fluorescence detection. Background Technology

[0002] The existing patent (publication number: CN106501047A) proposes a hot pressing device for plastic particles for infrared analysis and X-ray fluorescence detection, including the following steps: (1) placing an XRF Mylar membrane on the working tray, and then placing a plastic ring on the XRF Mylar membrane so that the working tray completely supports the plastic ring; (2) adding powder sample into the plastic ring, scraping and compacting it so that the powder is flush with the opening of the plastic ring, and obtaining the product to be made; (3) placing the product to be made on the pressing machine for pressing, removing the working tray after molding, and sealing the side of the sample that is in direct contact with the air with transparent tape. However, the "adding powder sample into the plastic ring, scraping and compacting" of this device requires manual scraping after the sample is placed in, which is cumbersome and affects the ease of use, and also causes some sample waste. Summary of the Invention

[0003] This invention addresses the aforementioned shortcomings of existing technologies by providing a plastic particle hot pressing device for infrared analysis and X-ray fluorescence detection. During the hot pressing process, plastic particles are placed inside a plastic particle support ring, completing the sample preparation. The device automatically flattens the plastic particles before compaction, resulting in a more uniform and convenient sample preparation that avoids sample waste.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A plastic granule hot pressing device for infrared analysis and X-ray fluorescence detection includes a main support base, a plastic granule carrying ring, a plastic granule carrying seat, a hot pressing block, a sealing cover, a lifting drive hydraulic cylinder, locking screws, a vibration drive motor, a vibration eccentric block, a heating element, a coolant supply pipe, and a return spring. The main support base has an auxiliary support claw on one side and a lower lifting cylinder connecting platform on the other side. Hot pressing block positioning rods are located on both sides of the main support base. A carrying seat support ring is located at the top of the main support base. The plastic granule carrying seat is placed on the carrying seat support ring and slides on the upper surface of the carrying seat support ring. A motor is located at the bottom of the plastic granule carrying seat. The mounting platform and motor mounting platform are located inside the support ring of the bearing seat. Multiple sets of return springs are installed between the inner wall of the support ring and the motor mounting platform. These return springs are evenly arranged around the motor mounting platform. One end of each return spring is fixedly connected to the motor mounting platform, and the other end is fixedly connected to the inner wall of the support ring. The vibration drive motor is inserted into and fixed inside the motor mounting platform. The drive shaft of the vibration drive motor is fixedly connected to the vibration eccentric block. The side of the plastic granule bearing seat has auxiliary bearing grooves. Multiple sets of auxiliary bearing grooves are evenly arranged around the central axis of the plastic granule bearing seat. The plastic granule bearing ring is adapted to the plastic granule bearing seat and is connected to the plastic granule bearing seat.

[0006] The plastic granule bearing ring is fitted around the outside of the plastic granule bearing seat. The bottom of the plastic granule bearing ring has an auxiliary bearing block. Multiple sets of auxiliary bearing blocks are evenly arranged around the central axis of the plastic granule bearing ring. The auxiliary bearing blocks are adapted to the auxiliary bearing grooves and connected to them. The auxiliary bearing blocks are inserted into the auxiliary bearing grooves, and their top planes coincide with the top plane of the plastic granule bearing seat. The side of the plastic granule bearing ring has a screw mounting platform, which is threadedly connected to a locking screw. The locking screw is pressed against the side of the plastic granule bearing seat. A hot-pressing block is provided at the top of the plastic granule bearing ring, adapting to it. The hot-pressing block has positioning grooves on both sides, which are adapted to positioning rods. The positioning rods connect to the positioning grooves, which slide outside the positioning rods. An upper lifting cylinder connecting platform is located on the side of the hot-pressing block corresponding to the lower lifting cylinder connecting platform.

[0007] 1. In the hot pressing sample preparation of plastic granules for infrared analysis and X-ray fluorescence detection, the plastic granules are placed inside the plastic granule support ring. The vibration drive motor is started, which drives the plastic granule support ring and the plastic granule support seat to vibrate, gradually flattening the plastic granules inside the support ring. After the plastic granules are flattened, the vibration drive motor is stopped, and the lifting drive hydraulic cylinder is started to press the hot pressing block down into the plastic granule support ring. Then, the heating plate is activated, and the plastic granules are heated. After a certain period of time, the plastic granule sample preparation is completed. Overall, the plastic granules can be automatically flattened before compaction, making the compacted plastic granule sample more uniform, more convenient to use, and without wasting samples.

[0008] 2. The hot pressing block of this utility model is equipped with a bottom cooling tank. After the plastic particles are hot-pressed, the coolant flows in from the coolant supply pipe. After the coolant passes through the bottom cooling tank, it cools the plastic particle sample, allowing the operator to remove the plastic particle sample more quickly and reducing the overall time of the sample preparation operation.

[0009] 3. The plastic particle support ring and plastic particle support base of this utility model adopt a split design, which allows the operator to loosen the locking screw and remove the plastic particle support ring when taking out the plastic particle sample. At this time, only the auxiliary support block supports the plastic particle sample, which makes it convenient for the operator to take out the plastic particle sample and increases the convenience of the sample preparation process.

[0010] 4. The plastic granule support ring of this utility model has a chamfer at the top. After the plastic granule support ring completes the vibration and leveling operation, even if the position of the plastic granule support ring and the hot pressing block is not completely corresponding, the chamfer of the plastic granule support ring can guide the hot pressing block and the plastic granule support ring to connect correctly, reducing the probability of abnormal connection between the plastic granule support ring and the hot pressing block, and increasing the stability of the sample preparation process.
