Description

Technical Field

[0001] The invention relates to the field of paperboard production devices, in particular to a drying device for corrugated paperboard production. Background Art

[0002] Corrugated cardboard is made up of multiple layers of paper, including face paper, lining paper and corrugated core paper. During the production process, if the paper contains too much moisture, the bonding force between the paper fibers will be weakened. Drying can reduce the moisture content of the paper, thereby significantly improving the mechanical properties of the cardboard, such as compressive strength and tensile strength.

[0003] The equipment on the market for drying corrugated cardboard can be divided into steam drying equipment, infrared drying equipment, hot air drying equipment, microwave drying equipment, etc. according to the working principle. Among them, infrared drying equipment uses infrared rays emitted by infrared radiators to irradiate the corrugated cardboard, so that the moisture in the cardboard absorbs the energy of the infrared rays and is converted into water vapor, thereby achieving drying.

[0004] However, the existing infrared drying equipment generally uses a conveyor chain plate to convey the corrugated cardboard, so that the lower part of the corrugated cardboard is blocked by the conveyor chain plate, so that the existing infrared drying equipment can only perform infrared irradiation on the upper side of the corrugated cardboard, resulting in uneven heating of the upper and lower sides of the corrugated cardboard, affecting the drying effect of the corrugated cardboard, and because the conveyor chain plate blocks the lower side of the corrugated cardboard, the water vapor generated on the lower side of the corrugated cardboard after drying cannot quickly leave the corrugated cardboard, causing the water vapor to gather at the bottom of the corrugated cardboard, further reducing the drying effect.

[0017] The beneficial effects of the present invention are as follows: 1. The present invention utilizes conveying rollers on a plurality of rectangular frames to support and limit the corrugated cardboard, and drives all the conveying rollers to rotate synchronously through a power assembly, so that the conveying rollers can convey the corrugated cardboard, thereby preventing the infrared illuminator disposed between the partition plates from being blocked, and further enabling the infrared illuminator to simultaneously irradiate and dry the upper and lower sides of the corrugated cardboard, thereby improving the drying effect.

[0018] Second, when the present invention uses a conveying roller to support and convey the corrugated cardboard, since the conveying roller is in a cylindrical structure, the contact area between the conveying roller and the corrugated cardboard is small, and since the position of the conveying roller remains unchanged, the water vapor evaporated from the lower side of the corrugated cardboard can be quickly discharged. In addition, the rotating assembly can drive the spiral rod to rotate, so that the spiral rod discharges the air inside the conveying roller to the left and right sides, so that a negative pressure state is formed inside the conveying roller, so that the conveying roller can quickly absorb the water vapor evaporated from the corrugated cardboard through the air guide holes thereon and discharge it to the left and right sides of the conveying roller, further improving the drying effect.

[0019] 3. The present invention adopts two corresponding upper and lower conveying rollers to clamp and support the corrugated cardboard, thereby increasing the friction between the corrugated cardboard and the conveying roller, so that the conveying roller can stably drive the corrugated cardboard to move, avoiding the corrugated cardboard from sliding and stagnating on the conveying roller, ensuring that the time for each position on the corrugated cardboard to be irradiated by the infrared irradiator is the same, thereby ensuring that the drying effect of each position on the corrugated cardboard is consistent.

[0020] 4. The present invention adopts a cooling component to quickly cool down the conveyor roller after the temperature rises, preventing the high-temperature conveyor roller from additionally heating the contact position of the corrugated support board, thereby further ensuring the consistent drying effect of various positions on the corrugated board. In addition, the infrared irradiator and the conveyor roller can be blocked to a certain extent by the partition board to prevent the conveyor roller from heating up quickly.

[0021] 5. When the present invention uses a rotating assembly to drive the spiral rod to rotate, the spiral rod and the conveying roller at the corresponding position can rotate in opposite directions, and the relative rotation speed of the spiral rod and the conveying roller is faster, thereby further increasing the exhaust effect of the spiral rod.

DETAILED DESCRIPTION

[0033] The embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. If no specific techniques or conditions are specified in the embodiments, the techniques or conditions described in the literature in the art or the product specifications are used.

[0034] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 A drying device for corrugated cardboard production includes an outer shell 1, a rectangular frame 2 is fixedly installed at equal intervals in the front and rear of the outer shell 1, the left and right sides of the top wall and the bottom wall of the rectangular frame 2 are extended to the outer side of the vertical section, and a conveying mechanism 3 for conveying corrugated cardboard is jointly provided on the rectangular frame 2 and the outer shell 1, a plurality of infrared irradiators 4 are provided inside the conveying mechanism 3, and an exhaust mechanism 5 is provided on the conveying mechanism 3.

[0035] When the corrugated cardboard needs to be dried, the operator first puts the corrugated cardboard into the front part of the outer shell 1, so that the conveying mechanism 3 continuously transports the corrugated cardboard to the rear side, and at the same time starts the infrared irradiator 4 to irradiate the upper and lower sides of the corrugated cardboard, so that the infrared irradiator 4 dries the upper and lower sides of the corrugated cardboard at the same time, and the conveying mechanism 3 synchronously drives the exhaust mechanism 5 to quickly discharge the steam generated on the upper and lower sides of the corrugated cardboard to the outside of the outer shell 1.

[0036] See also Figure 1 , Figure 2 , Figure 4 and Figure 8The conveying mechanism 3 includes two groups of symmetrically arranged partition plates 31 that are slid up and down inside the rectangular frame 2, each group is composed of two partition plates 31 that are symmetrically arranged front to back, and an infrared irradiator 4 is fixed between two adjacent partition plates 31 located on different rectangular frames 2. Two symmetrically arranged movable plates 32 are slid up and down on the vertical section of the rectangular frame 2, and a conveying roller 33 is rotated between the two corresponding movable plates 32 on the left and right of the same rectangular frame 2, and the conveying roller 33 is a hollow structure.

[0037] See also Figure 1 , Figure 2 and Figure 4 The exhaust mechanism 5 includes a cooling component 55 for cooling the conveying roller 33. The cooling component 55 includes a movable frame 551 symmetrically arranged inside the rectangular frame 2. The movable frame 551 is slidably connected to the rectangular frame 2 in the vertical direction. An adjustment plate 554 is fixedly installed on the side of the movable frame 551 away from the conveying roller 33. The adjustment plate 554 is fixedly connected to the two partition plates 31 at corresponding positions. The two frontmost adjustment plates 554 are rotatably provided with threaded rods 555 on the side away from the conveying roller 33. The threaded rods 555 are threadedly connected to the frontmost rectangular frame 2, and the ends of the threaded rods 555 pass through the outside of the outer shell 1.

[0038] Before drying the corrugated cardboard, the operator rotates the threaded rod 555 in advance according to the thickness of the corrugated cardboard, so that the threaded rod 555 drives the adjustment plate 554 to adjust the position up and down, the adjustment plate 554 drives the moving frame 551 to move synchronously with the partition plate 31, the partition plate 31 drives the infrared irradiator 4 to move synchronously, and the infrared irradiator 4 drives another partition plate 31 connected thereto to move synchronously, so that all the partition plates 31 on the upper side move synchronously with the infrared irradiator 4, and at the same time, all the partition plates 31 on the lower side move synchronously with the infrared irradiator 4. The infrared irradiator 4 moves to a position close to the upper and lower sides of the corrugated cardboard, and the partition plate 31 moves to a position close to the corrugated cardboard but not in contact with it, so that the partition plate 31 can separate the conveying roller 33 from the infrared irradiator 4 with the maximum area to prevent the conveying roller 33 from heating up quickly.

[0039] See also Figure 1 , Figure 2 , Figure 3 and Figure 4The conveying mechanism 3 also includes a power assembly 34 for driving the conveying roller 33. The power assembly 34 includes four driven pulleys 341 arranged in a rectangle and rotatably arranged on the left side of the rectangular frame 2. A tensioning block is slidably arranged at the rear part of the left side of the rectangular frame 2. A tensioning wheel 342 is rotatably arranged on the left side of the tensioning block. A tensioning spring is arranged between the front side of the tensioning block and the rectangular frame 2. A moving belt 343 is wound around the four driven pulleys 341, the tensioning wheel 342 and the left parts of the two conveying rollers 33 on the same rectangular frame 2. The inner side surface of the moving belt 343 contacts the upper conveying roller 33, and the outer side surface of the moving belt 343 contacts the lower conveying roller 33.

[0040] See also Figure 1 and Figure 2 An ear seat plate 344 is fixedly installed on the lower left part of the top wall of the rectangular frame 2, and a driving pulley 345 is rotatably arranged on the right side of the ear seat plate 344. The driving pulley 345 is fixedly connected to the driven pulley 341 at the corresponding position, and an execution motor 346 is fixedly installed on the front side of the outer shell 1. A belt is wound around the output shaft of the execution motor 346 and the outer side of the driving pulley 345.

[0041] When the position of the partition plate 31 is adjusted, the execution motor 346 is started to drive all the active pulleys 345 to rotate synchronously, and the active pulley 345 drives the driven pulley 341 connected thereto to rotate synchronously, and the driven pulley 341 drives the moving belt 343 thereon to start rotating, so that the moving belt 343 drives the upper conveying roller 33 to rotate forward, and at the same time, the moving belt 343 drives the lower conveying roller 33 to rotate in the opposite direction, thereby making the two conveying rollers 33 on the same rectangular frame 2 rotate synchronously in the opposite direction, and making all the conveying rollers 33 rotate at the same speed, so as to facilitate the stable conveying of the corrugated cardboard.

[0042] See also Figure 1 , Figure 4 , Figure 5 and Figure 6 The cooling component 55 also includes a moving part 556 jointly arranged on the rectangular frame 2 and the moving plate 32. The moving part 556 includes a sliding groove with an L-shaped cross-section and symmetrically opened on the right side wall of the rectangular frame 2. A sliding block 5561 is arranged inside the sliding groove to slide up and down. The sliding block 5561 on the rear side is fixedly connected to the moving plate 32 on the upper side, and the sliding block 5561 on the front side is fixedly connected to the moving plate 32 on the lower side. A hydraulic push rod 5564 is jointly arranged between the sliding block 5561 on the rear side and the bottom wall of the rectangular frame 2.

[0043] Continue reading Figure 1 , Figure 4 , Figure 5 and Figure 6A groove wheel 5562 is symmetrically arranged on the right side of the rectangular frame 2 for rotation. A steel wire rope 5563 is wound around the outer sides of the two groove wheels 5562 on the same rectangular frame 2. The rear side of the steel wire rope 5563 is fixedly connected to the sliding block 5561 on the rear side, and the front side of the steel wire rope 5563 is fixedly connected to the sliding block 5561 on the front side. A temperature sensor 5565 is fixedly installed on the side of the left movable plate 32 away from the middle of the outer shell 1. The hydraulic push rod 5564 is a digital hydraulic cylinder with a pressure sensor.

[0044] When the conveying roller 33 starts to rotate, the telescopic section of the hydraulic push rod 5564 is retracted, so that the hydraulic push rod 5564 drives the sliding block 5561 on the rear side to move downward, and the sliding block 5561 on the rear side drives the movable plate 32 connected to it on the upper side to move downward synchronously. At the same time, the sliding block 5561 on the rear side drives the sliding block 5561 on the front side to move upward by pulling the wire rope 5563, so that the sliding block 5561 on the front side drives the movable plate 32 connected to it on the lower side to move upward synchronously, and then the movable plates 32 on the upper and lower sides approach each other synchronously, and the movable plates 32 drive the conveying roller 33 to move synchronously.

[0045] When the conveying roller 33 moves to abut against the upper and lower sides of the corrugated cardboard, the conveying roller 33 is blocked by the corrugated cardboard, so that the pressure sensor on the hydraulic push rod 5564 begins to show a pressure value. When the hydraulic push rod 5564 drives the conveying roller 33 to abut against the corrugated cardboard with a preset pressure, the movement of the telescopic section of the hydraulic push rod 5564 is stopped, thereby ensuring that the friction force of the conveying roller 33 on the corrugated cardboard does not decrease and preventing the conveying roller 33 from clamping and deforming the corrugated cardboard.

[0046] When the conveying roller 33 is clamped on the corrugated cardboard, the rotating conveying roller 33 continuously pushes the corrugated cardboard to the rear side, and at the same time starts the infrared irradiator 4 to irradiate the upper and lower sides of the corrugated cardboard, so that the infrared irradiator 4 dries the upper and lower sides of the corrugated cardboard at the same time.

[0047] See also Figure 4 , Figure 5 , Figure 7 and Figure 8 The exhaust mechanism 5 also includes a plurality of air guide holes 51 which are evenly spaced along the circumference of the conveying roller 33. The air guide holes 51 connect the outer side with the inner side of the conveying roller 33. Follower support plates 52 are fixedly installed at both ends of the conveying roller 33. A screw rod 53 is provided between the two follower support plates 52 on the same conveying roller 33 so as to rotate together. A rotating assembly 54 for rotating the screw rod 53 is provided on the movable plate 32 on the right.

[0048] See also Figure 5 , Figure 7 and Figure 8The rotating assembly 54 includes a driving gear 541 fixedly mounted on the outer side of the right end of the conveying roller 33, a rotating column 542 rotatably connected to the moving plate 32 is arranged above the driving gear 541, a driven gear 543 meshing with the driving gear 541 is fixedly mounted on the rotating column 542, the number of teeth of the driving gear 541 is greater than the number of teeth of the driven gear 543, and the rotating column 542 is connected to the spiral rod 53 at the corresponding position through a belt.

[0049] When the conveying roller 33 starts to rotate, the conveying roller 33 drives the driving gear 541 thereon to rotate synchronously, and the driving gear 541 drives the driven gear 543 meshing therewith to rotate synchronously in the opposite direction. Since the number of teeth of the driving gear 541 is greater than the number of teeth of the driven gear 543, the rotation speed of the driven gear 543 is greater than the rotation speed of the driving gear 541. The driven gear 543 drives the screw rod 53 at the corresponding position to rotate synchronously through the rotating column 542, so that the screw rod 53 accelerates to rotate in the opposite direction relative to the conveying roller 33 coaxial with it.

[0050] See also Figure 5 , Figure 6 , Figure 7 and Figure 8 The screw rod 53 has a bidirectional spiral structure, and a gap is left between the outer side of the screw rod 53 and the inner side of the conveying roller 33. Fan blades 531 are fixed on both sides of the screw rod 53. The two fan blades 531 on the same screw rod 53 are arranged symmetrically, and the fan blades 531 are located on the inner side of the end of the conveying roller 33.

[0051] When the screw rod 53 rotates, the air inside the conveying roller 33 is pushed toward the left and right ends thereof, and the screw rod 53 drives the fan blades 531 to rotate synchronously, so that the fan blades 531 continuously draw the air inside the conveying roller 33 outward, thereby forming a negative pressure state inside the conveying roller 33, and then the conveying roller 33 continuously absorbs the steam on the corrugated cardboard into the inside thereof through the air guide holes 51 thereon, and then quickly discharges the steam through the screw rod 53 and the fan blades 531, thereby avoiding the accumulation of steam and improving the drying effect. In addition, since there is a gap between the outer side surface of the screw rod 53 and the inner side surface of the conveying roller 33, the frictional heat between the screw rod 53 and the conveying roller 33 is prevented, thereby preventing the conveying roller 33 from heating up quickly.

[0052] See also Figure 4-Figure 9 The cooling component 55 also includes a rotating plate 552 rotatably arranged inside the mobile frame 551. A power motor 553 is fixedly installed on the right side of the mobile frame 551. The output shaft of the power motor 553 is connected to the rotating plate 552 at the corresponding position. The side of the mobile frame 551 close to the conveying roller 33 is an arc-shaped structure, and the side of the mobile frame 551 away from the conveying roller 33 is provided with a ventilation groove running through from top to bottom.

[0053] When the conveying roller 33 conveys and exhausts the corrugated cardboard, the temperature of the conveying roller 33 is detected in real time through the temperature sensor 5565. When the value on the temperature sensor 5565 exceeds the preset standard value, the telescopic section of the hydraulic push rod 5564 is extended to drive the two conveying rollers 33 on the same rectangular frame 2 to move away from each other through the moving plate 32. On the one hand, the conveying roller 33 is moved away from the infrared irradiator 4 to cool down. On the other hand, the high-temperature conveying roller 33 is no longer in contact with the corrugated cardboard, thereby preventing inconsistent drying effects at different locations of the corrugated cardboard.

[0054] When the telescopic section of the hydraulic push rod 5564 is extended, the two power motors 553 on the same rectangular frame 2 are started, and the power motor 553 drives the rotating plate 552 to rotate, so that the rotating plate 552 blows air from the air permeable groove of the mobile frame 551 to the arc structure of the mobile frame 551. When the conveying roller 33 moves to the arc structure of the mobile frame 551 at the corresponding position, the rotating rotating plate 552 takes away the heat on the outer surface of the conveying roller 33, and at the same time, the spiral rod 53 continuously exhausts the inside of the conveying roller 33, so that the conveying roller 33 is quickly cooled down.

[0055] When the value on the temperature sensor 5565 returns to the preset standard value, the telescopic section of the hydraulic push rod 5564 is retracted and the conveying roller 33 is clamped on the corrugated cardboard again, thereby conveying and exhausting the corrugated cardboard. It should be noted that in order to ensure stable conveying of the corrugated cardboard by the conveying roller 33, in this embodiment, the telescopic sections of the hydraulic push rod 5564 can only be extended one by one, thereby ensuring that only one conveying roller 33 on the rectangular frame 2 is not in contact with the corrugated cardboard at a time.

[0056] See also Figure 1-Figure 9 When drying the corrugated cardboard, the present invention also includes the following steps: In the first step, the operator rotates the threaded rod 555 in advance according to the thickness of the corrugated cardboard, so that the threaded rod 555 adjusts the position of the partition plate 31 and the infrared irradiator 4, so that the partition plate 31 can separate the conveying roller 33 from the infrared irradiator 4 with the maximum area, preventing the conveying roller 33 from heating up quickly.

[0057] In the second step, the execution motor 346 is started to drive the two conveying rollers 33 on the same rectangular frame 2 to rotate synchronously in opposite directions, and then the telescopic section of the hydraulic push rod 5564 is retracted to drive the conveying rollers 33 to move to the upper and lower sides of the corrugated cardboard with a certain pressure, so that the rotating conveying rollers 33 continuously push the corrugated cardboard to the rear side, and at the same time, the infrared irradiator 4 is started to irradiate the upper and lower sides of the corrugated cardboard, so that the infrared irradiator 4 dries the upper and lower sides of the corrugated cardboard at the same time.

[0058] In the third step, the conveying roller 33 drives the spiral rod 53 inside it to rotate synchronously in the opposite direction, so that the spiral rod 53 pushes the air inside the conveying roller 33 to the left and right ends thereof, and the spiral rod 53 drives the fan blades 531 to rotate synchronously, so that the fan blades 531 continuously draw the air inside the conveying roller 33 outward, so that the conveying roller 33 continuously absorbs the steam on the corrugated cardboard into the inside through the air guide holes 51 thereon, and then quickly discharges the steam through the spiral rod 53 and the fan blades 531, thereby avoiding the accumulation of steam and improving the drying effect.

[0059] The fourth step is to detect the temperature of the conveyor roller 33 in real time through the temperature sensor 5565. When the value on the temperature sensor 5565 exceeds the preset standard value, the hydraulic push rod 5564 is extended to drive the conveyor roller 33 to move to the arc structure of the movable frame 551, and the two power motors 553 on the rectangular frame 2 at the corresponding position are started, so that the rotating plate 552 takes away the heat on the outer surface of the conveyor roller 33 by blowing air, and at the same time, the spiral rod 53 continuously exhausts the inside of the conveyor roller 33, so that the conveyor roller 33 is quickly cooled down.

[0060] In the fifth step, after the value on the temperature sensor 5565 returns to the preset standard value, the telescopic section of the hydraulic push rod 5564 is retracted and the conveying roller 33 is clamped on the corrugated cardboard again, thereby conveying and exhausting the corrugated cardboard.

[0061] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations on the present invention. A person skilled in the art may make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention and they are still covered by the protection scope of the present invention.
