Description

Technical Field

[0001] This utility model relates to the field of recycled polyester chip processing technology, and in particular to an environmentally friendly recycled polyester chip viscosity testing device. Background Technology

[0002] With the continuous improvement of modern technology, my country's chemical materials industry is developing rapidly. Polyester materials are among the most common chemical materials. Polyester chips typically refer to the sheet-like granules processed from polyester raw materials obtained through polymerization. Polyester production processes include direct esterification (PTA) and transesterification (DMT). Polyester chips are used in various fields, including fibers, containers, packaging materials, films, gels, and engineering plastics. Each type of polyester chip has a different application and viscosity; therefore, viscosity testing is crucial during the production process.

[0003] Existing polyester viscosity testing devices often use Ubbelohde viscometers to determine viscosity by measuring the speed and time of polyester solution dripping. However, when installing an Ubbelohde viscometer, it is usually clamped, requiring constant adjustment to ensure it is vertical. Furthermore, the Ubbelohde viscometer needs to be immersed in a constant-temperature solution before fixing, and the buoyancy of the solution causes it to shake, making adjustment difficult. Additionally, due to light refraction, the refracted light rays are deflected towards the water surface, making it difficult for users to accurately determine the angle of the Ubbelohde viscometer, necessitating constant adjustments and impacting the testing rate. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an environmentally friendly device for detecting the viscosity of recycled polyester chips.

[0007] A clamping assembly includes two sliding grooves, both of which are located on a positioning block away from the constant temperature chamber. Sliding blocks are slidably connected to each of the two sliding grooves. Clamping blocks are fixedly connected to the side walls of each of the two sliding blocks. Both clamping blocks are arc-shaped. Two rotating cavities are opened on the positioning block. Worm gears are rotatably connected to the inner walls of each of the two rotating cavities. Threaded rods are rotatably connected to the inner walls of each of the two sliding grooves. The two threaded rods are respectively fixedly connected to the two worm gears. The two sliding blocks are respectively threadedly connected to the two threaded rods. Worms are rotatably connected to the inner walls of each of the two rotating cavities. The two worms are respectively matched with the two worm gears. A rotating assembly is mounted on the fixed plate, and the rotating assembly is mounted on the two worms.

[0008] Furthermore, the rotating assembly includes a working cavity opened on a fixed plate. A rotating rod is rotatably connected to the inner wall of the working cavity. Two first bevel gears are fixedly connected to the side wall of the rotating rod. Two second bevel gears are rotatably connected to the inner wall of the working cavity. The two second bevel gears are fixedly connected to two worm gears. The two first bevel gears mesh with the two second bevel gears respectively. A third bevel gear is fixedly connected to the side wall of the rotating rod. The third bevel gear is located between the two first bevel gears. A fourth bevel gear is rotatably connected to the inner wall of the working cavity. The third bevel gear meshes with the fourth bevel gear. A knob rotatably passes through the fixed plate. One end of the knob is fixedly connected to the fourth bevel gear.

[0009] Furthermore, the adjustment assembly includes two adjustment ports on the support plate. The fixed plate slides within the two adjustment ports. An adjustment plate is fixedly connected to the fixed plate. A connecting plate is fixedly connected to the side wall of the support plate. A first spring is fixedly connected between the connecting plate and the adjustment plate. A fixed block is fixedly connected to the side wall of the support plate. An adjustment cavity is formed within the fixed block. A limit plate is slidably connected within the adjustment cavity. A set of second springs is fixedly connected to the inner wall of the adjustment cavity. All of the second springs are fixedly connected to the limit plate. A locking block is fixedly connected to the side wall of the limit plate. The locking block is wedge-shaped. A pull rod slides through the fixed block. One end of the pull rod is fixedly connected to the limit plate. The locking block slides through the fixed block. A locking groove is formed on the side wall of the adjustment plate. The locking block and the locking groove match.

[0010] Furthermore, the stirring assembly includes a stirring rod rotatably connected to the inner wall of the constant temperature chamber, and a drive motor is fixedly installed on the lower end face of the constant temperature chamber.

The clamping is more stable, and the Ubbelohde viscometer always remains vertical under the limit of the positioning groove. The operator does not need to repeatedly adjust the angle of the Ubbelohde viscometer, thus improving the installation efficiency.

[0015] 2. After the user has fixed the Ubbelohde viscometer, they press down the fixing plate. When the adjusting plate presses against the locking block, the locking block temporarily retracts into the adjusting cavity. When the locking slot is aligned with the locking block, the locking block automatically resets, fixing the adjusting plate and immersing the Ubbelohde viscometer in the constant temperature solution. When the user needs to disassemble the Ubbelohde viscometer, they pull the pull ring, and the first spring resets, allowing the Ubbelohde viscometer to be removed from the constant temperature solution. This allows the user to install and disassemble the Ubbelohde viscometer outside the constant temperature chamber, facilitating installation and disassembly and improving the portability of the device.

[0016] 3. When the constant temperature chamber heats the constant temperature solution, the drive motor starts to work, which makes the stirring rod continuously stir the solution, so that the solution is heated evenly and the solution is heated to the specified temperature more quickly, thus improving the detection efficiency.

[0028] The rotating assembly includes a working cavity 13 opened on the fixed plate 3. A rotating rod is rotatably connected to the inner wall of the working cavity 13.

The two second bevel gears 15 are fixedly connected to two worm gears 12. The two first bevel gears 14 mesh with the two second bevel gears 15 respectively. A third bevel gear 16 is fixedly connected to the side wall of the rotating rod. The third bevel gear 16 is located between the two first bevel gears 14. A fourth bevel gear is rotatably connected to the inner wall of the working cavity 13. The third bevel gear 16 meshes with the fourth bevel gear. A knob is rotatably passed through the fixed plate 3. One end of the knob is fixedly connected to the fourth bevel gear.

[0029] The adjustment assembly includes two adjustment ports on the support plate 2. The fixed plate 3 slides into the two adjustment ports.

[0030] The stirring assembly includes a stirring rod 26 rotatably connected to the inner wall of the constant temperature chamber 1. A drive motor 27 is fixedly installed on the lower end face of the constant temperature chamber 1.

After the user has secured the Ubbelohde viscometer 5, they press down on the fixing plate 3. The adjusting plate 17 then presses against the locking block 22, which is pushed by the second spring 21, causing the locking block 22 to temporarily retract into the adjusting cavity 20. When the locking groove 23 is aligned with the locking block 22, the second spring 21 returns to its original position, and the locking block 22 automatically moves into the locking groove 23, thus securing the adjusting plate 17 and immersing the Ubbelohde viscometer 5 in the constant-temperature solution. When the user needs to disassemble the Ubbelohde viscometer 5, they pull the pull ring 25 to remove the locking block 22 from the locking groove 23, and the first spring 18 returns to its original position, allowing the Ubbelohde viscometer 5 to be removed from the constant-temperature solution. This allows the user to install and disassemble the Ubbelohde viscometer 5 outside the constant-temperature chamber 1, facilitating installation and disassembly and improving the portability of the device.
