Technical Field

[0001] This utility model belongs to the technical field of drying equipment, specifically relating to a drying device for paperboard production. Background Technology

[0002] Dryers for paperboard production are key equipment in the paperboard manufacturing process. Their core function is to remove moisture from the paperboard to achieve the specified moisture content and physical performance indicators, ensuring that the paperboard quality meets production standards and application requirements. During the drying process, the hydrogen bonding between fibers is strengthened, which significantly improves the mechanical properties of the paperboard, such as stiffness, bursting strength, and folding endurance, meeting the usage requirements of packaging, printing, and other scenarios.

[0003] In modern paperboard production, the drying unit is a core piece of equipment, and its performance directly affects the quality and production efficiency of the paperboard. Currently, most paperboard drying units, in order to ensure the uniformity of the dried paperboard and the convenience of subsequent processing, typically have dedicated personnel at the discharge end to receive and sort the dried paperboard. Operators need to monitor the discharge process in real time and quickly collect and stack the paperboards that have just exited the drying unit. However, this traditional manual operation method undoubtedly increases the additional labor input, thereby increasing the company's production costs. Utility Model Content

[0004] The purpose of this invention is to provide a drying device for paperboard production, aiming to solve the problem that in most paperboard drying devices, to ensure the uniformity of the dried paperboard and the convenience of subsequent processing, dedicated personnel are usually assigned to receive and sort the dried paperboard at the discharge end. Operators need to constantly monitor the discharge process and quickly collect and stack the paperboards just output from the drying device. However, this traditional manual operation undoubtedly increases the labor input, thereby raising the production costs for enterprises.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drying device for cardboard production, including a dryer, one end of which is connected to the feed end, and the other end of which is connected to the discharge end, wherein a pallet is welded to the side of the discharge end away from the end connected to the dryer;

[0006] A feeding plate is provided in the recess of the pallet, and a crossbar is welded to the top of the recess of the pallet. A transfer plate is provided above the higher end of the feeding plate. The two sides of the transfer plate are welded to the inner wall of the corresponding side of the discharge end. The higher end of the transfer plate is opposite to the outer wall of the conveyor belt on the discharge end, and the gap between the transfer plate and the outer wall at the corner of the conveyor belt is less than the thickness of the cardboard.

[0007] In order to enable the height of the feeding plate to be adjusted, as a drying device for paperboard production according to this utility model, preferably, a connector is welded to each side of the feeding plate near the higher end, and the other end of each connector is welded to the bottom of a slider, and one side of the slider is connected to the connecting rod.

[0008] A rotating tongue is rotatably installed in the openings at both ends of the connecting rod. The rotating tongue at the lower end of the connecting rod is connected to the slider. The rotating tongue at the upper end of the connecting rod is movably installed in the crossbar. A sliding groove is vertically opened on the inner wall of the recess on both sides of the support plate. A slider is movably installed in the interior of each sliding groove.

[0009] In order to fix the feeding plate in the recess of the pallet, as a drying device for paperboard production according to the present invention, preferably, a slot is opened in the interior of both ends of the crossbar, the openings on the upper and lower sides of the slot extend to the surfaces of the upper and lower sides of the crossbar, and the rotating tongue above the connecting rod moves through the opening on the lower side of the slot and extends into the interior of the slot.

[0010] Each of the aforementioned through slots has a spring installed horizontally inside. The ends of the two springs that are far apart from each other are respectively connected to a connecting plate. The other side of the connecting plate is fixedly installed on the outer wall of the rotating tongue above the connecting rod.

[0011] A tightening rod is installed through the upper opening of the slot. The bottom of the tightening rod extends into the interior of the slot and is fixedly connected to the top of the rotating tongue above the docking rod. A nut is threaded onto the outer wall of the slot near the tightening rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] When in use, place the collection frame for collecting dry cardboard below the lower end of the feed plate. When the cardboard that needs to be dried flows into the dryer through the feed end, the dryer will dry the wet cardboard. The dried cardboard will then flow into the discharge end.

[0014] Before the dried cardboard flows onto the transfer plate, the operator needs to adjust the position of the feed plate in advance. During adjustment, the operator loosens the nut on the tensioning rod, allowing it to move within the slot. The movement of the tensioning rod moves the connecting tongue, which pulls the connecting rod to one side. This causes the other end of the connecting rod to pull the slider upwards within the chute via the corresponding rotating tongue. The upward movement of the chute then moves the feed plate upwards via the connecting parts, ensuring the feed plate is properly positioned below the transfer plate.

[0015] After the dried cardboard falls onto the transfer plate, it will slide down the inclined surface of the transfer plate onto the feeding plate, and then slide down the inclined surface of the feeding plate into the collection box below. In use, this structure can automatically collect the dried cardboard, which can reduce the input of manual labor and thus reduce costs. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 The present invention provides the following technical solution: a drying device for paperboard production, including a dryer 1, one end of the dryer 1 is connected to the feed end 2, the other end of the dryer 1 is connected to the discharge end 3, and a pallet 4 is welded to the side of the discharge end 3 away from the end connected to the dryer 1.

[0025] A feeding plate 5 is provided in the recess of the pallet 4. A crossbar 6 is welded to the top of the recess of the pallet 4. A transfer plate 7 is provided above the higher end of the feeding plate 5. The two sides of the transfer plate 7 are welded to the inner wall of the corresponding side of the discharge end 3. The higher end of the transfer plate 7 is opposite to the outer wall of the conveyor belt on the discharge end 3, and the gap between the transfer plate 7 and the outer wall at the corner of the conveyor belt is less than the thickness of the cardboard.

[0026] During operation, the operator places the cardboard to be dried on the conveyor belt at the feed end 2. The conveyor belt transports the cardboard into the dryer 1. Once inside the dryer 1, the heating system and ventilation device within the dryer 1 dry the wet cardboard through heat conduction and hot air circulation. The dried cardboard is then further transported to the discharge end 3 and collected.

[0027] Preferably, a connector 51 is welded to each of the two sides of the feed plate 5 near the higher end, and the other end of each connector 51 is welded to the bottom of a slider 52. One side of the slider 52 is connected to the connecting rod 53.

[0028] A rotating tongue 54 is rotatably installed in the openings at both ends of the connecting rod 53. The rotating tongue 54 at the lower end of the connecting rod 53 is connected to the slider 52. The rotating tongue 54 at the upper end of the connecting rod 53 is movably installed in the crossbar 6. A sliding groove 41 is vertically opened on the inner wall of the recess on both sides of the support plate 4. A slider 52 is movably installed inside each sliding groove 41.

[0029] In practical use, the docking rod 53 and the two rotating tongues 54 are rotatably connected by a smooth rod, and the opening size on the docking rod 53 is larger than the rotation trajectory size of the rotating tongues 54.

[0030] Preferably, a slot 61 is provided inside the two ends of the center line of the crossbar 6, and the openings on the upper and lower sides of the slot 61 extend to the upper and lower surfaces of the crossbar 6, respectively. The rotating tongue 54 above the connecting rod 53 moves through the opening on the lower side of the slot 61 and extends into the interior of the slot 61.

[0031] Inside each through slot 61, a spring 62 is installed horizontally. The ends of the two springs 62 that are far apart from each other are respectively connected to a connecting plate 63. The other side of the connecting plate 63 is fixedly installed on the outer wall of the rotating tongue 54 above the connecting rod 53.

[0032] When the tightening rod 64 moves the corresponding rotating tongue 54 horizontally, it lifts the bottom of the docking rod 53 upwards. Additionally, the movement of the rotating tongue 54 inside the slot 61 moves the corresponding connecting plate 63, which in turn compresses the spring 62. When the tightening rod 64 needs to reset later, the spring 62 releases its potential energy, causing the tightening rod 64 to automatically reset.

[0033] A tightening rod 64 is installed through the upper opening of the slot 61. The bottom of the tightening rod 64 extends into the interior of the slot 61 and is fixedly connected to the top of the rotating tongue 54 above the docking rod 53. A nut is threaded onto the outer wall of the tightening rod 64 near the slot 61.

[0034] In practical use, before using the cardboard dryer 1 for cardboard drying, the position of the feed plate 5 needs to be adjusted according to the conveying path of the dried cardboard to ensure that the dried cardboard falls smoothly into the pre-set collection frame. The specific operating procedure is as follows:

[0035] First, the collection frame for collecting the dried cardboard is placed below the lower end of the feed plate 5. When the wet cardboard to be dried enters the dryer 1 through the feed end 2, the dryer 1 uses its built-in heating system and ventilation device to dry the wet cardboard through heat conduction and hot air circulation. After drying, the cardboard moves towards the end of the discharge end 3 under the drive of the conveying mechanism between the feed end 2 and the discharge end 3.

[0036] Before the dried cardboard flows to the transfer plate 7, the operator needs to adjust the position of the feed plate 5 in advance. The specific adjustment steps are as follows: The operator first loosens the nut on the tightening rod 64 to release the fixing restriction on the tightening rod 64. At this time, the tightening rod 64 can move freely in the empty slot 61. When the tightening rod 64 moves, the rotating tongue 54 connected to it will move synchronously. The rotating tongue 54 pulls the connecting rod 53 to one side through the rotating structure at the end connected to the connecting rod 53. The other end of the connecting rod 53 will then pull the slider 52 to slide upward inside the slide 41 through the corresponding rotating tongue 54. During the upward movement of the slider 52 in the slide 41, it will drive the feed plate 5 to move upward synchronously through the connecting piece 51. Through this series of linkage structures, the feed plate 5 can be accurately adjusted to a suitable position directly below the transfer plate 7 to ensure that the dried cardboard can fall smoothly into the feed plate 5.

[0037] Once the dried cardboard falls onto the transfer plate 7, it slides down naturally under gravity due to the inclined angle of the transfer plate 7, landing smoothly on the feed plate 5. The cardboard then continues to slide down the inclined surface of the feed plate 5, eventually falling accurately into the collection box below. The entire process requires no manual intervention, achieving automatic collection of the dried cardboard, effectively improving the automation level and efficiency of the cardboard drying operation, and reducing manual labor input.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
