[0016] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] For example, see Figure 1 - Fig.10The present invention provides a technical solution for a drying device for rapid production of cartons: the drying device for rapid production of cartons comprises: a carton drying box 1 and a conveying mechanism 11, the outer wall on one side of the carton drying box 1 is fixedly connected to the outer wall on one side of the conveying mechanism 11, multiple bases 7 are fixedly connected to both sides of the outer wall of the conveying mechanism 11, and the multiple bases 7 are movably inserted with equipment shells 41 inside, multiple equipment shells 41 are movably contacted with fixed grooves 4 on the outer walls on one side, and the tops of the multiple fixed grooves 4 are fixedly connected with support plates 53, multiple temporary storage boxes 3 are fixedly connected to both sides of the inside of the carton drying box 1, a dryer 2 is fixedly connected to the outer wall of the top of the carton drying box 1, and the output end of the dryer 2 passes through the outer wall of the top of the carton drying box 1 and is fixedly connected to a diverter box 21, and both sides of the bottom of the diverter box 21 are fixedly connected to air transfer pipes 22, and the outer wall of the air transfer pipe 22 is fixedly connected to the outer wall of the air inlet 32.

[0018] By inserting the cardboard into the opening of the fixing groove 4, the cardboard stands above the conveying mechanism 11. The standing of the cardboard increases the contact area with the hot air, thereby improving the drying efficiency. Standing drying helps to maintain the shape and dimensional stability of the cardboard, reduces deformation or warping that may occur during the drying process, and improves the efficiency of the overall production line and product quality.

[0019] Embodiment 2, on the basis of embodiment 1, a slide groove connecting the outer walls on both sides is opened on the support plate 53, a T-shaped block 5 is slidably connected inside the slide groove, an outer wall on one side of the T-shaped block 5 is fixedly connected to a U-shaped elastic plate 51, a plurality of L-shaped limit rods 52 are fixedly connected to the two sides of the outer wall on one side of the U-shaped elastic plate 51, a plurality of fixed rods 54 are fixedly connected to the outer walls on both sides of the support plate 53, and the inner part of the L-shaped limit rod 52 is in movably contact with the outer wall of the fixed rod 54.

[0020] By pulling the U-shaped elastic plate 51 upward, the height of the U-shaped elastic plate 51 on the supporting plate 53 can be adjusted, so that the U-shaped elastic plate 51 can fix the cardboard higher. The U-shaped elastic plate 51 can tightly wrap the cardboard, especially for cardboard with a higher height, providing additional support and fixation, avoiding the cardboard from tilting and bending due to excessive weight above, and correspondingly ensuring the stability of the cardboard during the drying process.

[0021] Embodiment 3, on the basis of embodiment 2, a track groove 45 is provided on the outer wall of one side of the temporary storage box 3, a guide rod 43 is fixedly connected to the outer wall of one side of the fixed groove 4, a rotating roller 44 is rotatably connected to the inside of the guide rod 43, the outer wall of the rotating roller 44 is rotatably connected to the inside of the track groove 45, the interior of the temporary storage box 3 is fixedly connected to the mounting groove 33, an air outlet groove is provided on one side of the temporary storage box 3 located inside the track groove 45, a moving rod 35 is movably inserted inside the air outlet groove, a push spring 34 is fixedly connected to the outer wall of one side of the moving rod 35, the outer wall of one end of the push spring 34 is fixedly connected to the inside of the mounting groove 33, the outer wall of one side of the moving rod 35 is movably contacted with the outer wall of one side of the guide rod 43, an air inlet 32 ​​is provided in the middle of one side of the temporary storage box 3, and the outer walls on both sides of the temporary storage box 3 are fixedly connected to connecting pipes 31.

[0022] The guide rod 43 enters the track groove 45, and then slowly moves upward along the track of the track groove 45. At this time, the fixed groove 4 drives the cardboard to move upward on the equipment shell 41, so that the equipment shell 41 can be staggered and raised inside the carton drying box 1, increasing the gap between the cardboards, making it easier for the heat flow to enter the gap of the cardboard. The increase in the gap makes it easier for the hot air to penetrate into the gap of the cardboard, thereby drying the cardboard more directly and effectively, avoiding the problem of uneven drying caused by too dense stacking of cardboards. Correspondingly, the cardboards arranged in a staggered manner can be more fully heated by the heat flow, so the drying efficiency is significantly improved.

[0023] Embodiment 4, on the basis of embodiment 3, a reset spring 63 is fixedly connected to the lower part of the interior of the device shell 41, a slider 42 is fixedly connected to the outside of the top of the reset spring 63, an outer wall on one side of the slider 42 is fixedly connected to the outer wall on one side of the fixing groove 4, an outer wall of the slider 42 is slidably connected to the interior of the device shell 41, a tooth seat 62 is fixedly connected to one side of the interior of the device shell 41, a groove is provided on one side of the slider 42 close to the tooth seat 62, a fixing rod 2 6 is fixedly connected to the interior of the groove, an outer wall of the fixing rod 2 6 is rotatably connected to the limiting wheel 61, and an outer wall of the limiting wheel 61 is meshedly connected to the outer wall of the tooth seat 62.

[0024] When the fixed slot 4 starts to fall on the equipment shell 41, the cooperation between the tooth seat 62 and the limiting wheel 61 can avoid the huge impact force caused by the excessively fast falling speed of the fixed slot 4, and accordingly protect the stability of the cardboard during the transmission process, and prevent the cardboard from being displaced or damaged due to impact. Then, by setting the reset spring 63, the stability of the slider 42 is increased when the slider 42 slides down. The elasticity of the spring can absorb part of the kinetic energy during the sliding process, reduce vibration and shaking, and thus increase the stability of the slider 42 and the fixed slot 4 during the sliding process.

[0025] In actual use, first, start the dryer 2, and then the inside of the carton drying box 1 can be heated through the operation of the dryer 2, and then the fixed groove 4 is inserted into the inside of the base 7 on the conveying mechanism 11, so that the openings on the two fixed grooves 4 are opposite, and then the cardboard is inserted into the openings on the fixed grooves 4, so that the cardboard stands above the conveying mechanism 11. The standing of the cardboard increases the contact area with the hot air, thereby improving the drying efficiency. Standing drying helps to maintain the shape and dimensional stability of the cardboard, reduces deformation or warping that may occur during the drying process, and improves the efficiency of the overall production line and product quality.

[0026] It should be noted that when the height of the cardboard is too high, if it is only fixed by the fixing groove 4, the upper part of the cardboard will be heavier, so that the cardboard will tilt, which may easily cause the cardboard to bend above the fixing groove 4, causing the cardboard to pile up, affecting the drying effect.

[0027] When the U-shaped limit rod 52 moves upward, the bottom of the L-shaped limit rod 52 reaches the top of the fixing rod 1 54, and the fixation between the L-shaped limit rod 52 and the support plate 53 can be released. At this time, the U-shaped elastic plate 51 is moved horizontally, and the T-shaped block 5 and the L-shaped limit rod 52 can be driven to move to the left at the same time. At this time, the outer walls on both sides of the T-shaped block 5 are closely fitted with one side of the support plate 53, and the L-shaped limit rod 52 moves out from between the two fixing rods 1 54. A gap is generated between the U-shaped elastic plate 51 and the paperboard. At this time, the U-shaped elastic plate 51 is pulled upward to move, and the U-shaped elastic plate 51 can be adjusted on the support plate 53. 3, so that the U-shaped elastic plate 51 can better fix the cardboard, and the U-shaped elastic plate 51 can tightly wrap the cardboard, especially for the cardboard with a higher height, providing additional support and fixation, avoiding the cardboard from tilting and bending due to excessive weight on the top, and correspondingly ensuring the stability of the cardboard during the drying process, and then the U-shaped elastic plate 51 can closely fit the cardboard and effectively fix it, the cardboard can remain flat and stable during the drying process, avoiding the problem of uneven drying caused by cardboard deformation, and correspondingly improving the drying efficiency of the cardboard, while ensuring the quality of the cardboard after drying, and then through the linkage mechanism between the U-shaped elastic plate 51 and the L-shaped limiting rod 52, the T-shaped block 5 and the support plate 53, the operator can easily adjust the height of the U-shaped elastic plate 51 on the support plate 53, this height adjustment function enables the device to adapt to cardboards of different heights, and improves the versatility and flexibility of the device.

[0028] After the U-shaped elastic plate 51 is fixed at a suitable position above the cardboard, the U-shaped elastic plate 51 is pushed rightward, so that the U-shaped elastic plate 51 can drive the L-shaped limiting rod 52 to enter the gap between the two fixing rods 54, and then the U-shaped elastic plate 51 is pushed downward, so that the U-shaped elastic plate 51 can drive the L-shaped limiting rod 52 to be fixed on the fixing rod 54, thereby limiting and fixing the position of the U-shaped elastic plate 51 on the supporting plate 53, ensuring that the position of the U-shaped elastic plate 51 on the supporting plate 53 is accurately limited and fixed, thereby increasing the fixing stability of the U-shaped elastic plate 51 to the cardboard.

[0029] Then, the conveying mechanism 11 is started to work. Through the movement of the conveying mechanism 11, the fixed groove 4 drives the cardboard to be conveyed to the inside of the carton drying box 1. When the fixed groove 4 drives the guide rod 43 to move to the position of the temporary storage box 3, the height of the guide rod 43 is flush with the height of the track groove 45. At this time, when the fixed groove 4 continues to drive the guide rod 43 to move, the rotating roller 44 movably connected to the guide rod 43 can increase the efficiency of the guide rod 43 moving in the track groove 45, so that the guide rod 43 can enter the inside of the track groove 45, and then slowly move along the track of the track groove 45. The fixed groove 4 drives the cardboard to move upward on the device shell 41, so that the device shell 41 can be staggered and raised inside the carton drying box 1, increasing the gap between the cardboards, making it easier for the heat flow to enter the gap of the cardboard. The increase in the gap makes it easier for the hot air to penetrate into the gap of the cardboard, thereby drying the cardboard more directly and effectively, avoiding the problem of uneven drying caused by too dense stacking of cardboards. Correspondingly, the cardboards arranged in a staggered manner can be more fully heated by the heat flow, so the drying efficiency is significantly improved.

[0030] Then, through the cooperation of the diverter box 21 and the air transfer pipe 22, the hot air is transferred to the interior of the temporary storage box 3. Then, through the setting of the connecting pipe 31, multiple temporary storage boxes 3 can be connected in series, so that the hot air enters the interior of the temporary storage box 3. At this time, when the guide rod 43 moves to the interior of the track groove 45, it will push the moving rod 35, so that the moving rod 35 leaves the air outlet and enters the interior of the temporary storage box 3, so that the air outlet is opened, so that the hot air enters the inside of the two cardboards and the bottom of the lifted cardboard. The hot air can be used to dry the cardboard more directly and effectively, and the time required for the entire drying process can be shortened accordingly, which not only improves production efficiency, but also reduces energy consumption and production costs. The hot air is directly blown into the inside of the cardboard and the bottom of the lifted cardboard, which helps to eliminate the temperature gradient during the drying process and makes the cardboard heated more evenly.

[0031] When the guide rod 43 moves out from the track groove 45, the moving rod 35 can be pushed back to its original position under the action of the pushing spring 34, so that the interior of the temporary storage box 3 is in a closed state and sufficient hot air is collected. When the moving rod 35 is opened, a large amount of hot air can quickly flow out from the interior of the temporary storage box 3 and blow toward the paperboard. The temporary storage box 3 is in a closed state, which effectively reduces the loss of hot air, maintains the temperature and humidity of the hot air, helps to reduce energy waste, and improves the energy efficiency of the drying process. The hot air is released in a concentrated manner and blows toward the paperboard quickly, which helps to reduce the temperature gradient during the drying process.

[0032] When the fixed slot 4 starts to fall on the equipment shell 41, the limiting wheel 61 can be rotated on the fixed rod 6 through the cooperation between the tooth seat 62 and the limiting wheel 61, thereby reducing the speed at which the fixed slot 4 drives the slider 42 to slide downward inside the equipment shell 41, avoiding the huge impact force generated by the fixed slot 4 falling too fast, and correspondingly protecting the stability of the cardboard during the transmission process, preventing the cardboard from being displaced or damaged due to impact. Then, through the setting of the reset spring 63, when the slider 42 slides down, the stability of the slider 42 is increased, and the elasticity of the spring can absorb part of the kinetic energy during the sliding process, reduce vibration and shaking, thereby increasing the stability of the slider 42 and the fixed slot 4 during the sliding process.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
