Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paper processing, in particular to a spray humidifying device for producing corrugated paper online. Background Art

[0002] The corrugated cardboard production line, referred to as the corrugated line, is the key production equipment of corrugated box manufacturers. The corrugated cardboard production line is the most important production line equipment in carton packaging companies, including wet equipment, dry equipment, production management system and other important components.

[0003] As disclosed in Chinese patent document CN219276846U, a humidifying device for corrugated paper production includes two support rods and a humidifying nozzle, and also includes two mounting rings arranged on the support rods, a control box for controlling the size of water mist sprayed by the humidifying nozzle, and baffles arranged on both sides of the humidifying nozzle. The two mounting rings are arranged at intervals along the length direction of the support rods, and the baffles are arranged on the mounting rings. The mounting rings are provided with fixings for fixing the baffles to the mounting rings. The present application has the effect of reducing the impact of the humidifying device on the humidity of the entire workshop.

[0004] The spray port of the humidifying device is vertically arranged on the corrugated paper conveying line. Due to the continuous conveying of the conveyor belt, the contact time of the corrugated paper with the spray is too short and the spray port can only humidify the upper surface of the corrugated paper. After the mist contacts the corrugated paper, dewdrops will form on the surface of the corrugated paper and cannot penetrate into the inside of the corrugated paper. As a result, the overall humidification degree of the corrugated paper is low, affecting the production of corrugated paper. Therefore, there is an urgent need for an online production of corrugated paper spray humidifying device. Utility Model Content

[0005] 1. Technical Problems to be Solved by the Utility Model

[0006] In view of the problems existing in the prior art, the purpose of the utility model is to provide an online spray humidification device for producing corrugated paper, which improves the humidification uniformity of the corrugated paper by setting two humidification rollers, thereby solving the quality problems caused by uneven humidification of corrugated paper during production.

[0007] 2. Technical solution

[0008] To solve the above problems, the utility model adopts the following technical solutions.

[0009] The invention discloses an online spray humidifying device for producing corrugated paper. The structure of the device comprises a conveyor belt, a motor, and a humidifying mechanism fixed on the conveyor belt. The humidifying mechanism comprises a shell, a paper inlet and a paper outlet respectively arranged on both sides of the shell, and a roller with two openings connected to facilitate the conveying of corrugated paper, a mist outlet pipe penetrating one side of the shell, and a bearing is pivotally connected to one end of the mist outlet pipe, a humidifying roller connected to the bearing, and a connecting rod at one end of the humidifying roller is hung inside the shell in cooperation with the mist outlet pipe. After the two humidifying rollers rotate, they cooperate with the mist outlet pipe pivotally connected at one end to pass water mist into the rollers, and finally discharge the water mist from the through hole, so that the water mist discharged by the upper and lower humidifying rollers contacts the upper and lower surfaces of the corrugated paper, and the gap between the two humidifying rollers is constant. The roller driven to rotate by the motor allows the convex strip to first drag the corrugated paper, and the convex strip will be compressed at the gap between the two rollers, so that the other roller can be driven to rotate while dragging the corrugated paper.

[0010] As an optimization, the humidifying roller includes a through hole that penetrates the wall of the roller and cooperates with the mist outlet pipe to discharge water mist, and a convex strip made of gelatin material embedded on the outside to increase the friction between the roller and the corrugated paper.

[0011] As an optimization, the outer shell includes a bottom plate arranged at the bottom to separate the humidification mechanism from the conveyor belt, and a water collecting trough is provided on the bottom plate for collecting water mist condensation beads after they fall. The water that slides into the trough after the water mist condenses beads will flow back to the water tank from a return pipe connected on one side.

[0012] As an optimization, the mist outlet pipe includes a connecting pipe connecting the two mist outlet pipes and the other end is connected to a water tank and a return pipe connected to the upper end of the water tank, and the other end of the return pipe is connected to the outer shell and is at the same level as the water collecting tank.

[0013] As an optimization, a guide portion toward between the two humidifying rollers is provided on the bottom plate near the paper inlet.

[0014] As an optimization, the two humidifying rollers are tilted, and the inner diameter of the upper mist outlet pipe is smaller than that of the lower one. The difference in the inner diameters of the mist outlet pipes at the upper and lower ends makes the water mist in the lower mist outlet pipe more than that in the upper one. In this way, the upper and lower surfaces of the corrugated paper can be exposed to the water mist, while the excess water mist at the bottom can be condensed on the outer shell, collected by the water collecting trough on the bottom plate, and then returned to the water tank through the reflux pipe.

[0015] As an optimization, the connecting pipe on the lower humidifying roller away from the mist outlet pipe side is directly connected to the motor, and the motor is synchronized with the conveyor belt, so that the rotation rate of the humidifying roller is synchronized with the conveyor belt. The humidifying roller below is driven by the motor so that the convex strips arranged on the cylinder wall utilize the gelatin material used to increase the contact friction when in contact with the corrugated paper. The conveyor belt brings the corrugated paper from the paper inlet on the shell into the humidifying mechanism, and cooperates with the guide part arranged on the bottom plate to guide the corrugated paper into between the humidifying rollers. Through the above technical solution, the rotating roller brings the corrugated paper out from the paper outlet.

[0016] 3. Beneficial effects

[0017] Compared with the prior art, the utility model has the following advantages: the utility model is an online spray humidifying device for producing corrugated paper. Through the humidifying structure arranged on the conveyor belt, the corrugated paper can be fed between two humidifying rollers in cooperation with the paper outlet and paper inlet at the front and rear ends, and the water mist discharged from the inside of the humidifying roller is used to contact the upper and lower surfaces of the corrugated paper, thereby solving the problem of uneven humidification of the corrugated paper in the past. The two rollers are used to press the water droplets on the corrugated paper to fall off or accelerate their fusion into the corrugated paper to improve the humidification rate. The water mist condensation beads flowing on the outer shell and the water droplets falling on the corrugated paper will be collected in the water collecting trough and flow into the water tank through the reflux pipe. In summary, while improving the uniformity of the humidification of the corrugated paper, the degree of fusion of the water droplets and the corrugated paper is improved, and the remaining water can be recycled.

[0025] Example

[0026] See also Figure 1-5A spray humidifying device for online production of corrugated paper, the structure of which includes a conveyor belt 3, a motor 1, and a humidifying mechanism 7 fixed on the conveyor belt 3, the humidifying mechanism 7 includes a shell 30, a paper inlet 33 and a paper outlet 31 respectively arranged on both sides of the shell 30, and the two openings are connected to a roller that is convenient for conveying corrugated paper, a mist outlet pipe 11 that passes through one side of the shell 30 and one end of the mist outlet pipe 11 is pivotally connected to a bearing, a humidifying roller 70 connected to the bearing, and a connecting rod at one end of the humidifying roller 70 is matched with the mist outlet pipe 11 and hung inside the shell 30.

[0027] After the two humidifying rollers 70 rotate, they cooperate with the mist outlet pipe 11 pivotally connected at one end to pass the water mist into the rollers and finally discharge the water mist from the through hole 37, so that the water mist discharged from the upper and lower humidifying rollers 70 contacts the upper and lower surfaces of the corrugated paper, and the gap between the two humidifying rollers 70 is constant. The rollers driven to rotate by the motor allow the convex strips 90 to first drag the corrugated paper and the convex strips 90 will be compressed at the gap between the two rollers, so that the other roller can be driven to rotate while dragging the corrugated paper.

[0028] In this embodiment, the humidifying roller 70 includes a through hole 37 penetrating through the wall of the roller to cooperate with the mist outlet pipe 11 to discharge water mist, and a convex strip 90 made of gelatin embedded on the outer side to increase the friction between the roller and the corrugated paper.

[0029] In this embodiment, the housing 30 includes a bottom plate 51 disposed at the bottom end so as to separate the humidifying mechanism 7 from the conveyor belt 3 , and a water collecting tank 50 for collecting the water mist condensed beads after they fall is disposed on the bottom plate 51 .

[0030] The water in the water collecting groove 50 that slides into the groove after the water mist condenses into beads will flow back to the water tank 5 through the return pipe 9 connected to one side.

[0031] In this embodiment, the mist outlet pipe 11 includes a connecting pipe 10 connecting the two mist outlet pipes 11 and the other end is connected to the water tank 5, and a return pipe 9 connected to the upper end of the water tank 5. The other end of the return pipe 9 is connected to the outer shell 30 and is at the same level as the water collecting tank 50.

[0032] In this embodiment, a guide portion is provided on the side of the bottom plate 51 close to the paper inlet 33 and directed toward the space between the two humidifying rollers 70 .

[0033] In this embodiment, the two humidifying rollers 70 are arranged at an angle, and the inner diameter of the mist outlet pipe 11 located at the upper one is smaller than that of the mist outlet pipe 11 located at the lower one.

[0034] The difference in the inner diameter of the mist outlet pipe 11 at the upper and lower ends is set so that the water mist of the lower mist outlet pipe 11 will be more than that of the upper one, so that the upper and lower surfaces of the corrugated paper can be exposed to the water mist, while the excess water mist at the bottom can be collected by the water collecting trough 50 on the bottom plate 51 and then flow back to the water tank 5 through the reflux pipe 9 while condensing on the outer shell 30.

[0035] In this embodiment, the connection pipe of the lower humidifying roller 70 away from the mist outlet pipe 11 is directly connected to the motor, and the motor is synchronized with the conveyor belt 3, so that the rotation speed of the humidifying roller 70 is synchronized with the conveyor belt.

[0036] The humidifying roller 70 at the bottom is driven by a motor so that the convex strips 90 arranged on the wall of the roller use the gelatin material to increase the contact friction when in contact with the corrugated paper. The conveyor belt 3 brings the corrugated paper into the humidifying mechanism 7 from the paper inlet 33 on the shell 30, and the guide part arranged on the bottom plate 51 guides the corrugated paper into the humidifying roller 70, and the corrugated paper is taken out from the paper outlet 31 by the rotating roller.

[0037] The driving motor of the humidifying roller 70 is turned on, and the corrugated paper is manually placed on the side of the paper inlet 33, and the corrugated paper is brought into the humidifying mechanism 7 through the conveyor belt 3. Through the guide part tilted toward the space between the two humidifying rollers 70 set on the bottom plate 51, the humidifying roller 70 rotating below cooperates. When the convex strip 90 contacts the corrugated paper, the corrugated paper is brought to the other side by the humidifying roller 70 and taken out of the humidifying mechanism 7 from the paper outlet 31, and transported to the next process by the conveyor belt 3.

[0038] When the corrugated paper is in the humidifying mechanism 7: the connecting pipe 10 passes the water mist into the humidifying roller 70, and then the water mist is discharged to the outside through the through hole 37. The water mist discharged from the two humidifying rollers 70 will contact the upper and lower surfaces of the corrugated paper, and because the gap between the two humidifying rollers 70 is certain, the water droplets that are not integrated on the corrugated paper will be removed and dropped into the water collecting tank 50. The reflux pipe 9 connected to the water collecting tank 50 condenses the dropped water mist and flows back to the water tank 5 to complete the collection of the remaining water.
