When testing the properties such as the thermal stability of textiles, the textiles need to be placed in the electric heating oven, set a specific temperature according to relevant standard requirements and maintain it for a certain period of time, and then measure parameters such as the dimensional change rate to judge the material properties.

[0003] However, the existing electric heating ovens have many drawbacks. When it is necessary to disassemble the textiles after the detection, once the oven door is opened, the heat inside the oven body will quickly dissipate, which leads to the need to reheat the equipment to the set temperature during the next use, greatly increasing the energy consumption and causing energy waste; moreover, since the temperature inside the oven body is still relatively high after the detection, there is a risk of scalding for the operator to directly perform the disassembly operation, and during the loading and unloading process, the clamping plate is not fixed and is prone to shaking, and the high-temperature environment is also not conducive to the accurate and safe disassembly of the textiles, seriously affecting the operation efficiency and personnel safety.

[0019] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0020] Embodiment 1: As shown in Figures 1 to 8As shown in the figure, an electric drying oven includes an electric drying oven body 1. Inside the electric drying oven body 1, there is a partition 13 with a through hole 131 opened, and a first sealing plate 14 and a second sealing plate 141 that are adapted to the size of the through hole 131. The first sealing plate 14 and the second sealing plate 141 are used to seal the electric drying oven body 1 during detection and disassembly. A substrate 15 for placing materials is installed between the first sealing plate 14 and the second sealing plate 141; A positioning and feeding assembly is installed on the electric drying oven body 1. The positioning and feeding assembly includes an adjusting roller 3. A combined groove 32 formed by alternating combinations of two pairs of feeding grooves 321 and locking grooves 322 is opened on the adjusting roller 3, and the combined groove 32 is slidably connected to a fixed block 33 on the side wall of the second sealing plate 141. A turntable 34 is installed on the adjusting roller 3, and a protrusion 341 for clamping at the bottom of the fixed block 33 and corresponding to the locking groove 322 is installed on the turntable 34. The positioning and feeding assembly is used to unlock first and then push the second sealing plate 141 to slide; A self-unlocking assembly is installed on the substrate 15. The self-unlocking assembly includes a rocker arm 2 rotatably installed on the substrate 15. The self-unlocking assembly is used to drive the rocker arm 2 to flip when the second sealing plate 141 slides to the through hole 131, and unlock the materials on the substrate 15.

[0021] As Figures 1 to 8 shown, in the specific implementation, a sealing door 11 is rotatably installed at the inlet of the electric drying oven body 1. An observation window 111 is installed on the sealing door 11. Both the observation window 111 and the partition 13 are made of transparent materials, which is convenient for the operator to observe the situation inside the box at any time. A handle 112 is installed on the sealing door 11, and the handle 112 is provided with an anti-slip groove to improve the holding stability during operation. Support legs 12 are installed at the bottom of the electric drying oven body 1, and anti-slip pads are installed at the bottom of the support legs 12 to enhance the stability of the equipment when placed.

[0022] As Figures 1 to 8 shown, further, the partition 13 is installed on the inner wall of the electric drying oven body 1 by bolts. A guide rod 144 is installed between the inner side wall of the partition 13 and the inner side wall of the electric drying oven body 1. The guide rod 144 is rectangular, and a slide plate 143 is slidably installed on the guide rod 144. The slide plate 143 is installed on the side wall of the second sealing plate 141. The guide rod 144 and the slide plate 143 serve the purpose of guiding. A synchronizing rod 142 is installed between the first sealing plate 14 and the second sealing plate 141. The synchronizing rod 142 is used to drive the first sealing plate 14 and the second sealing plate 141 to move synchronously.

[0023] Example 2: The difference between this example and Example 1 is: As Figures 1 to 8As shown in the figure, a positioning shaft 21 is installed at the rotation center of the swing arm 2. The positioning shaft 21 is rotatably installed on the substrate 15. The substrate 15 is in a bent state. A number of pairs of ventilation openings 151 are provided at the center position of the substrate 15, which helps the gas flow during the drying process of the material. A pressure roller 23 is installed at the end of the swing arm 2. The pressure roller 23 is attached to the substrate 15. The swing arm 2 is in an inclined state, which facilitates the clamping operation in the later stage through the pressure roller 23.

[0024] As Figures 1 to 8 shown, in the specific implementation manner, a positioning sleeve 25 is installed on the back surface of the second sealing plate 141. A baffle 251 is slidably installed inside the positioning sleeve 25. One end of the baffle 251 is connected to the ejector rod 24, and the ejector rod 24 is inserted into the positioning sleeve 25. The other end of the baffle 251 is installed with a connecting rod 261. The connecting rod 261 movably penetrates through the positioning sleeve 25. The end of the connecting rod 261 is installed with a synchronous frame 26. A return spring 252 is sleeved on the connecting rod 261 located inside the positioning sleeve 25. One end of the return spring 252 is clamped on the positioning sleeve 25, and the other end of the return spring 252 is clamped on the baffle 251. A top plate 262 is installed on the synchronous frame 26. A top block 263 is installed on the top plate 262. The top block 263 is slidably connected to the top of the second sealing plate 141, and the top block 263 corresponds to the partition 13. A limiting rod 264 is movably inserted on the top plate 262. One end of the limiting rod 264 is installed on the side wall of the second sealing plate 141, and the other end of the limiting rod 264 is installed with a limiting plate 265. The diameter of the limiting plate 265 is larger than the diameter of the limiting rod 264. An ejector rod 24 is movably inserted between the first sealing plate 14 and the second sealing plate 141. A sliding rod 241 is installed through the inside of the ejector rod 24. A strip-shaped groove 22 is opened inside the swing arm 2. The strip-shaped groove 22 is slidably connected to the sliding rod 241. When the second sealing plate 141 slides to the through hole 131, at this time, the top block 263 installed on the back surface of the second sealing plate 141 is blocked by the partition 13. Then the top block 263 drives the top plate 262 to move away from the positioning sleeve 25, and the top plate 262 slides along the limiting rod 264 at this time, mainly serving the purpose of limiting, and the limiting plate 265 at the end of the limiting rod 264 ensures that the limiting rod 264 and the top plate 262 will not separate. When the top plate 262 slides, the top plate 262 drives the synchronous frame 26 to slide, and the connecting rod 261 on the synchronous frame 26 pulls the baffle 251 to move, compressing the return spring 252. It is convenient for later resetting by compressing the return spring 252. At the same time, the baffle 251 drives the ejector rod 24 to move, and the ejector rod 24 can slide horizontally inside the second sealing plate 141. During the sliding process of the ejector rod 24, the ejector rod 24 can drive the sliding rod 241 to slide. At this time, the sliding rod 241 slides in the strip-shaped groove 22 opened inside the swing arm 2, thereby driving the swing arm 2 to rotate around the positioning shaft 21. Finally, the pressure roller 23 at the end of the swing arm 2 gradually lifts, and the flipping of the swing arm 2 unlocks the fiber textiles tightly attached to the substrate 15.

[0025] Embodiment 3: The difference between this embodiment and Embodiment 2 is as follows: As Figures 1 to 8 shown, a synchronous shaft 31 is installed at the rotation center of the adjusting roller 3. The synchronous shaft 31 movably penetrates through the side wall of the electrothermal drying oven body 1 and the side wall of the partition 13. A knob 311 is installed at the end of the synchronous shaft 31. The knob 311 is attached to the partition 13. The synchronous shaft 31 is connected to the rotation center of the turntable 34. The operator can conveniently control the actions of the adjusting roller 3 and related components by rotating the knob 311.

[0026] As Figures 1 to 8 shown, in the specific implementation manner, the feed groove 321 is a spiral groove, the locking groove 322 is a straight groove, the combined groove 32 is annular, the central angles corresponding to the feed groove 321 and the locking groove 322 are ninety degrees, and the central angle of the protrusion 341 is the same as that of the locking groove 322.

[0027] As Figures 1 to 8 shown, further, a slider 332 is slidably installed on the combined groove 32. A vertical rod 331 is installed on the slider 332. The top of the vertical rod 331 is connected to the bottom of the fixed block 33. Two clamping grooves 342 are formed at the bottom of the fixed block 33, and the clamping grooves 342 correspond to the protrusions 341, and the two clamping grooves 342 are respectively located on both sides of the vertical rod 331. Through this precise structural design, precise locking and unlocking of related components are realized.

[0028] The implementation principle of an electrothermal drying oven of the present invention is as follows: When the present invention is in normal use, at this time, the fiber textile is placed on the substrate 15, and the fiber textile is closely attached to the bent substrate 15. The substrate 15 as a whole is located in the chamber of the partition 13 and the electrothermal drying oven body 1, ensuring that the first sealing plate 14 covers the through hole 131 of the partition 13 to seal the through hole 131. Then the operator starts the electrothermal drying oven body 1, and the fiber textile inside can be heated and warmed up through the electrothermal drying oven body 1 to facilitate the later detection requirements.

[0029] After the heating is completed, the operator can open the sealing door 11. Then the operator rotates the knob 311. The knob 311 drives the synchronous shaft 31 to rotate. The synchronous shaft 31 drives the entire adjusting roller 3 to start rotating. At this time, the position of the combined groove 32 on the adjusting roller 3 changes. So when the adjusting roller 3 just starts to rotate, at this time, the slider 332 on the combined groove 32 slides in the locking groove 322. Therefore, the slider 332 will not slide horizontally. However, in this process, the turntable 34 on the adjusting roller 3 rotates. Finally, the protrusion 341 on the turntable 34 is separated from the clamping groove 342. Then the first sealing plate 14, the second sealing plate 141 connected to the fixed block 33 and the substrate 15 installed with the material are unlocked at this time.

[0030] As the adjusting roller 3 continues to rotate, at this time, the slider 332 slides into the feeding groove 321. Since the feeding groove 321 is a spiral groove, the fixed block 33 will push the second sealing plate 141 to slide along the direction of the guide rod 144 under its action. The second sealing plate 141 drives the first sealing plate 14 to move synchronously through the synchronous rod 142, so that the first sealing plate 14 gradually disengages from the through hole 131.

[0031] When the second sealing plate 141 slides to the position of the through hole 131, at this time, the second sealing plate 141 perfectly takes over the first sealing plate 14 to effectively seal the internal chamber, ensuring that the heat inside the sealed chamber will not be dissipated and maintaining good heat preservation performance. At the same time, the substrate 15 originally located in the chamber of the partition 13 and the electrothermal drying oven body 1 is brought to the outside due to the sliding of the second sealing plate 141. This change in position greatly facilitates the operator to disassemble and assemble the substrate 15, and the fiber textiles heated and dried on the substrate 15 can be conveniently taken out, and then subsequent detection and other work processes can be carried out.

[0032] And when the second sealing plate 141 slides to the through hole 131, the top block 263 installed on the back of the second sealing plate 141 is blocked by the partition 13 at this time. Then the top block 263 drives the top plate 262 to move away from the positioning sleeve 25. At this time, the top plate 262 slides along the limiting rod 264, mainly serving the purpose of limiting, and the limiting plate 265 at the end of the limiting rod 264 ensures that the limiting rod 264 and the top plate 262 will not separate.

[0033] When the top plate 262 slides, the top plate 262 drives the synchronous frame 26 to slide, and the connecting rod 261 on the synchronous frame 26 pulls the baffle 251 to move, compressing the return spring 252. Facilitating later resetting by compressing the return spring 252. At the same time, the baffle 251 drives the ejector rod 24 to move, and the ejector rod 24 can slide horizontally inside the second sealing plate 141. During the sliding process of the ejector rod 24, the ejector rod 24 can drive the sliding rod 241 to slide. At this time, the sliding rod 241 slides in the strip-shaped groove 22 opened inside the rocker arm 2, thereby driving the rocker arm 2 to rotate around the positioning shaft 21. Finally, the pressing roller 23 at the end of the rocker arm 2 is gradually lifted, and the flipping of the rocker arm 2 unlocks the fiber textiles tightly attached to the substrate 15.

[0034] After the substrate 15 has completely slipped out, the operator does not need to reverse-rotate the knob 311 at this time, but continues to rotate the knob 311. The adjusting roller 3 will continue to rotate. When the slider 332 slides along the feed groove 321 of the adjusting roller 3 to move to another locking groove 322, the protrusion 341 on the turntable 34 will then be inserted into another card slot 342 at the bottom of the fixing block 33, smoothly achieving the re-locking of components such as the substrate 15. At this time, the operator can conveniently take out the heat-dried fiber textiles on the substrate 15 for subsequent inspections and other operations. And at this time, the substrate 15 is in a locked state, making it more convenient to take and install fiber textiles later, and preventing the substrate 15 from shifting and affecting the operation efficiency.
