Description

Technical Field

[0001] The invention relates to the technical field of drying and drying, in particular to a device for testing the moisture content of polyester chips. Background Art

[0002] Polyester materials are widely used in textile, packaging, electronics and other fields due to their excellent physical and chemical properties, such as high strength, chemical corrosion resistance and good processing performance. In the production and processing of polyester, the drying process is crucial, especially in high-precision processes such as spinning and injection molding. The moisture content of polyester chips must be strictly controlled to ensure product quality. To control the moisture content of polyester chips, it is necessary to test their moisture content; the moisture content test of polyester chips generally involves drying the polyester chips. The moisture content of polyester chips is the ratio of the weight difference of the polyester chips before and after drying to the weight before drying, that is, (weight before measurement - weight after measurement) / weight before measurement = moisture content.

[0003] Traditional drying methods mainly rely on hot air or vacuum environment to remove moisture from polyester chips. Since polyester chips are easily piled up during the drying process, the hot air circulation is poor or the heat conduction efficiency is low, which makes some chips incompletely dried, affecting the quality of subsequent processing. Traditional polyester chip drying methods have disadvantages such as uneven drying, low thermal efficiency, and high energy consumption. The poor drying efficiency of polyester chips affects the final performance of polyester materials.

[0004] Therefore, it is necessary to provide a new polyester chip moisture content testing device to achieve complete and uniform drying of the polyester chips, thereby improving the accuracy of the moisture content test. Summary of the invention

When the worm 305 rotates, the worm 305 can drive the second clamping seat 303 to flip the angle through the worm gear shaft 304 to adjust the clamping angle of the polyester slice.

[0086] During implementation, when the polyester slice is connected between the first clamping seat 301 and the second clamping seat 303 and the second clamping seat 303 rotates around its own axis, due to the rotational connection between the first clamping seat 301 and the placement box 204, the first clamping seat 301 will also rotate synchronously with the second clamping seat 303, thereby realizing the deflection movement of the polyester slice, realizing the angle adjustment of the polyester slice, and achieving full contact between the polyester slice and the hot air blown in by the air inlet pipe 7, and the upper and lower sides of the polyester slice can be evenly dried by the first electric heating wire 403, realizing full and uniform drying of the polyester slice.

When the hot air passes from the wind box 501 into the placement box 204 in the upper space of the test box 1, the polyester chips can be dried.

[0093] Specifically, a dust filter and a fan are fixedly installed inside the fan box 502. The dust filter can prevent dust from entering the fan box 502. The fan is used to supply air to the heating box 503 to achieve air supply heating of the second heating wire 504. After the test, the first heating component 4 and the second heating component 5 are turned off, and the air supply from the fan can be used to cool the interior of the test box 1.

[0094] During implementation, the control panel 401 is operated to control the heating of the first heating wire 403 and the second heating wire 504. An infrared temperature sensing probe is fixedly connected to the right side of the temperature detector 402. A signal processor is provided inside the control panel 401. The infrared temperature sensing probe is connected to the signal processor through a temperature control circuit. During implementation, the internal temperature of the test box is monitored by the infrared temperature sensing probe, and the measured temperature information is transmitted to the signal processor. The control panel 401 receives the temperature information and adjusts the heating power of the first heating wire 403 and the second heating wire 504 in real time through the temperature control circuit to achieve temperature control inside the test box 1.

[0095] Specifically, the infrared temperature sensing probe of the temperature detector 402 can monitor the temperature data inside the test box 1 in real time, and transmit the temperature data to the signal processor inside the control panel 401.

[0096] like Figure 4 As shown, the heating box 503 is a cylindrical structure, and at least one second heating wire 504 is arranged inside.

[0097] Furthermore, in order to enhance the preheating effect of the bellows 501 on the air, in the present embodiment, a heating box 503 is fixedly connected to the inner bottom wall of the bellows 501, and a second heating wire 504 is fixedly installed in the heating box 503; the heating box 503 is heated by the second heating wire 504, and thus the air can quickly exchange heat and heat up when flowing through the heating box 503, thereby realizing rapid preheating of the gas, and then the hot air can be passed into the upper layer of the test box 1 to perform hot air drying on the polyester chips.

[0098] Furthermore, in order to promote the rapid upgrading of air and reduce the energy consumption of the second heating wire 504, in this embodiment, Figure 6As shown, baffles 506 are provided at the upper and lower ends of the heating box 503 to contact the upper and lower sides of the inner wall of the wind box 501, and a plurality of air holes 505 are opened on the side of the heating box 503, so that air enters the interior of the heating box 503 through the air holes 505 on one side to exchange heat with the second heating wire 504, flows out from the air holes 505 on the other side, and then enters the upper layer of the test box 1 through the air inlet pipe 7 to dry the polyester chips.

[0099] Preferably, if Figure 7 As shown, in order to further improve the preheating effect of the air, a plurality of heat exchange spokes 507 are connected between the second electric heating wire 504 and the heating box 503; preferably, the heat exchange spokes 507 are made of ceramic material and are bonded and fixed to the second electric heating wire and the inner wall of the heating box 503 by high temperature resistant glue. The second electric heating wire 504 heats up after being energized, and can heat the heat exchange spokes and the heating box 503. After the air flows through the heating box 503, it quickly exchanges heat and heats up with the heating box 503 and the heat exchange spokes 507 and the second electric heating wire 504 inside, so that the gas can be raised to a preset temperature in a very short time, promoting the flow speed of the hot air used for drying in the test box 1, and thus improving the drying efficiency of the polyester chips.

[0100] like Figure 2 As shown, the back of the test box 1 is fixedly connected with an air inlet duct 7 and an air exhaust duct 8, and the back wall panel of the test box 1 is provided with an air inlet 120 and an air outlet 103, wherein the air inlet 102 is connected to the air inlet duct 7, and the air outlet 103 is connected to the air outlet duct 8; the air inlet 120 and the air outlet 103 are fixedly connected with filter screens; the air inlet duct 7 connects the ventilation box 501 and the upper space of the test box 1; the bottom of the exhaust duct 8 passes through the back of the cold water tank 601 and is connected to the left end of the heat pipe 603, and the right end of the heat pipe 603 passes through the cold water tank 601 and is connected to the right wall of the test box 1, so as to discharge the hot air.

[0101] In a specific embodiment of the present invention, a cooling assembly 6 is provided at the lower layer of the test box 1; Figure 3 As shown, the cooling assembly 6 includes: a cold water tank 601, a heat conduction plate 602 and a heat conduction pipe 603; wherein, the cold water tank 601 stores low-temperature liquid; the heat conduction plate 602 is arranged in the cold water tank 601, and a heat conduction pipe 603 is fixedly arranged on the surface of the heat conduction plate 602, one end of the heat conduction pipe 603 is connected to the upper layer of the test box 1 through the exhaust pipe 8, and the other end is connected to the external environment, which is used to export the gas from the upper layer of the test box 1.

[0102] Preferably, the heat pipe 603 is made of metal copper or copper alloy; the heat conducting plate 602 is made of graphene.

[0103] Specifically, a cold water box 601 is arranged in parallel on the side of the wind box 501 , a heat conducting plate 602 is fixedly connected inside the cold water box 601 , and a heat conducting pipe 603 is fixedly connected to the side of the heat conducting plate 602 .

[0104] like Figure 3 As shown, the heat conducting pipe 603 is arranged in an S shape on the heat conducting plate 602, and the heat conducting pipe 603 is formed by connecting a plurality of S-shaped bent pipes in sequence.

[0105] In this embodiment, alternatively, the heat conducting pipe 603 is nested inside the heat conducting plate 602. Further, the heat conducting plate 602 and the heat conducting pipe 603 are arranged in one or more groups in the cold water tank 601. When there are multiple groups of heat conducting plates 602 and heat conducting pipes 603, they are arranged in parallel in the cold water tank 601, and the multiple heat conducting pipes 603 are connected in parallel and are all connected to the exhaust pipe 8.

[0106] Specifically, the hot air heated by the second heating component 5 is sent into the test box 1 by using the air inlet pipe 7, so as to speed up the air flow rate and heat exchange rate inside the test box 1, and after the polyester chips are thermally dried, the hot air is introduced into the copper structure heat pipe 603 through the exhaust pipe 8, and the heat pipe 603 with excellent thermal conductivity is used to transfer heat to the heat conduction plate 602, and then the graphene material heat conduction plate 602 is used to evenly radiate heat to the cooling water in the cold water tank 601, so as to cool the air and reduce the influence of the hot air discharged on the surrounding environment.

[0107] Furthermore, after the cold water tank performs heat exchange on the hot air with a certain amount of water vapor, the water vapor liquefies and adheres to the wall of the heat pipe 603. Long-term use may cause water accumulation inside the heat pipe 603 and affect the use effect; therefore, in this embodiment, a drainage structure is connected to the bottom of the heat pipe 603 to drain the liquid water in the heat pipe 603.

[0108] like Figure 8 As shown, the drainage structure includes: a drain pipe 604, a branch pipe 605 and a water pipe 606; wherein the drain pipe 604 is fixedly arranged at the bottom of the side panel of the test box 1; the water pipe 606 is arranged inside the cold water tank 601, and the side of the water pipe 606 is connected with multiple branch pipes 605 in parallel, and each branch pipe 605 is connected to the bottom of the heat pipe 603; when in use, the multiple branch pipes 605 can introduce the water accumulated at the bottom of the heat pipe 603 into the water pipe 606, and then discharged from the drain pipe 604.

[0109] It is worth noting that when no liquid is produced in the heat pipe 603, the drain pipe 604, the branch pipe 605 and the water pipe 606 can also be used as air pipes for conducting hot air.

[0110] When the moisture content of polyester chips is tested using the testing device of the present invention:

[0111] Firstly, after the polyester material to be tested is sliced, the irregular polyester slices to be tested are weighed.

[0112] Secondly, open the sealed box door 101, drive the threaded screw 202 to drive the placement box 204 to slide forward along the slide 218 through the reduction motor 203, and then control the micro motor 210 to drive the first eccentric wheel 207 and the second eccentric wheel 214 to rotate, and drive the translation seat to move relative to the placement box 204 through two linkage rods to adjust the clamping distance of the clamping assembly 3. Then, put the irregular polyester slice to be tested into the middle slot of the first clamping seat 301 and the second clamping seat 303, and use the micro air pump 302 to vacuum absorb the surface of the polyester slice to be tested or tighten the adjustment screw to clamp and fix the polyester slice; after the polyester slice is fixed, control the placement box 204 to slide backward through the reduction motor 203, and close the sealed box door 101;

[0113] The control panel 401 is operated to set the upper layer of the test box 1 to different heating temperatures between 150°C and 170°C, and the first heating wire 403 and the second heating wire 504 are used for heating, and the temperature detector 402 is used to monitor the internal temperature of the test box 1 in real time. When drying the polyester slices, the worm 305 is rotated, and the worm gear shaft 304 is driven by the worm 305 to adjust the clamping angle of the polyester slice to be tested, and the polyester slice is driven to rotate by the worm gear shaft 304 to achieve multi-angle blowing and drying; at the same time, the reduction motor 203 drives the placement box 204 to move back and forth through the threaded screw 202 and the slide 218, so that the polyester slices are evenly and fully dried in the moving state.

[0114] After the heating is completed, the first heating wire 403 and the second heating wire 504 stop heating, and the fan box 502 continues to ventilate the inside of the test box 1 through the heating box 503, and the hot air inside the test box 1 is passed into the heat pipe 603 and evenly radiated to the heat conducting plate 602. At the same time, the cooling water in the cold water tank 601 is used to cool the hot air; the sealed box door 101 is opened, and the threaded screw 202 is driven by the reduction motor 203 again to drive the placement box 204 to slide forward, and the dehydrated polyester chips are taken out and weighed, so as to calculate the moisture content of the polyester chips.

[0115] Compared with the prior art, the technical solution provided by this embodiment has at least one of the following beneficial effects:

[0116] 1. The polyester chip moisture content testing device of the present invention drives the threaded screw 202 to rotate forward / reversely through the reduction motor 203, and then the threaded screw 202 drives the slide 218 and the placement box 204 to move forward and backward. By realizing the forward and backward movement of the placement box 204, the polyester chip and the clamping component 3 can be conveniently fixed, and when the polyester chip is heated and dried by the first heating component 4 and the second heating component 5, the threaded screw 202 is driven by the reduction motor 203 to switch forward and reverse, so that the placement box 204 can reciprocate in the test box 1, and then the polyester chip can be driven to reciprocate in the test box 1, so that the polyester chip can be dried during the movement, the uniformity of drying is promoted, and the drying efficiency is improved.

[0117] 2. The polyester chip moisture content testing device of the present invention starts the micro motor 210 according to the size of the polyester chip, and uses the micro motor 210 to drive the double-headed pulley, which drives the first eccentric wheel 207 and the second eccentric wheel 214 to rotate through the second belt transmission mechanism 209 and the third belt transmission mechanism 211 respectively. The rotation directions of the first eccentric wheel 207 and the second eccentric wheel 214 are opposite, thereby driving the first translation seat 205 and the second translation seat 206 to slide in the placement box 204, adjusting the spacing of the clamping assembly 3, and then placing the polyester chip between the first clamping seat 301 and the second clamping seat 303 of the clamping assembly 3, starting the micro air pump 302 at the bottom of the first clamping seat 301 to adsorb and fix the polyester chip, and then rotating the adjusting screw at the top of the second clamping seat 303 to fix the polyester chip for a second time through the pressing pad, thereby achieving the effect of protecting and fixing the polyester chip.

[0118] 3. The polyester chip moisture content testing device of the present invention drives the worm gear shaft 304 to rotate through the worm 305, thereby realizing the rotation of the second clamping seat 303 and the first clamping seat 301, and can realize the rotation of the polyester chip; the present invention promotes the evaporation and gasification of the surface moisture of the polyester chip by rotating the polyester chip, thereby achieving a more uniform and sufficient drying effect, and thus being able to obtain more accurate moisture content data.

[0119] 4. The polyester chip moisture content testing device of the present invention controls the first heating wire 403 and the second heating wire 504 to heat the test box 1 through the control panel 401. The first heating wire 403 can provide a drying effect, and the second heating wire 504 is used to heat the air and then blow hot air to remove moisture from the polyester chips. After the heating is completed, the first heating wire 403 and the second heating wire 504 are turned off, and the fan in the fan box 502 is continued to be used to ventilate the inside of the test box 1 to accelerate the air flow rate. After the hot air flows through the upper space of the test box 1, it enters the heat pipe 603 through the exhaust pipe 8, and the heat is evenly transferred to the cooling water in the cold water tank 601 by the heat conducting plate 602. While quickly dissipating the heat in the test box 1, it can prevent the ambient temperature from being affected by the high temperature of the test.

[0120] 5. The present invention evenly disperses multiple polyester slices by arranging multiple groups of clamping components 3, ensuring that each slice can fully contact the drying medium (hot air), thereby improving the uniformity and sufficiency of drying.
