Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of packaging machinery, and particularly relates to a humidifying spray device for corrugated cardboard. Background Art
[0002] As is well known, corrugated cardboard, also known as corrugated board, is composed of at least one layer of corrugated paper and one layer of linerboard bonded together. It has good elasticity and extensibility and is mainly used for manufacturing cartons, the sandwich of cartons, and other packaging materials for fragile goods.
[0003] Currently, some corrugated cardboard needs to be embossed or indented during the production process. Since the surface of the corrugated paper is relatively dry, it is easy to cause damage to the corrugated paper. Therefore, before embossing or indenting it, the corrugated cardboard generally needs to be spray humidified to prevent the corrugated cardboard from bursting due to excessive dryness during the creasing process. However, currently, when humidifying the corrugated cardboard, most often a vertical air pipe is installed beside the production line conveyor belt to humidify the corrugated cardboard on the conveyor belt. However, the humidifying effect of this humidifying method is poor, and it cannot effectively humidify the surface of the parts on the corrugated cardboard that are to be grooved and embossed. Moreover, it causes a lot of waste of water resources and fails to achieve the purpose of both fully humidifying the corrugated cardboard and saving water resources, thus greatly increasing the production cost of the corrugated cardboard. Summary of the Utility Model
[0004] The technical problem to be solved by the utility model is to provide a humidifying spray device for corrugated cardboard, which can fully spray and humidify the parts to be processed of the corrugated cardboard, improve the humidifying effect, and achieve the purpose of saving water resources. The adopted technical scheme is as follows:
[0005] A humidifying spray device for corrugated cardboard includes a frame and a conveying mechanism. The conveying mechanism is installed on the frame and has a conveying surface that moves from front to back. It is characterized in that: the humidifying spray device further includes a spray mechanism and two upper pressing mechanisms. The spray mechanism includes a water vapor generating device, at least one vertical air pipe, and at least one atomizing nozzle. The vertical air pipe is installed on the frame and is directly above the middle of the conveying surface of the conveying mechanism. The upper end of the vertical air pipe is communicated with the water vapor outlet of the water vapor generating device. The atomizing nozzle is installed at the lower end of the vertical air pipe, and the inner cavity of the atomizing nozzle is communicated with the vertical air pipe. The atomizing nozzle has a plurality of water spraying ports, and each water spraying port faces upward above the middle of the conveying surface of the conveying mechanism. The two upper pressing mechanisms are arranged side by side on the left and right sides of the spray mechanism. The upper pressing mechanism includes an upper pressing block and a lifting assembly for driving the upper pressing block to lift and lower. The upper pressing block is directly above the conveying surface of the conveying mechanism.
[0006] During operation, the conveying mechanism is used to convey corrugated cardboard. It drives the corrugated cardboard to move forward to backward in an intermittent manner through its conveying surface, passing right below the spraying mechanism and the two upper pressing mechanisms. During this process, the parts of the upper surface of the corrugated cardboard that are to be grooved and molded gradually move past right below each atomizing nozzle. During the process when the conveying mechanism pauses the movement of the corrugated cardboard, first, the lifting components of the two upper pressing mechanisms drive the upper pressing blocks to move downward, pressing both sides of the corrugated cardboard tightly against the conveying surface of the conveying mechanism. Then, the steam generating device of the spraying mechanism conveys steam to each vertical air pipe, and then sprays it through each water spraying orifice of the atomizing nozzle onto the parts of the corrugated cardboard to be processed, realizing sufficient spray humidification of the parts of the corrugated cardboard to be processed at this position. Subsequently, the spraying mechanism stops working, and the lifting components of the two upper pressing mechanisms drive the upper pressing blocks to move upward and reset, preparing for the next spray humidification of the next position of the parts of the corrugated cardboard to be processed. By repeating the above process, this humidifying spray device can achieve sufficient humidification of the parts of the corrugated cardboard to be processed, improve the humidification effect, effectively reduce the waste of water resources, achieve the purpose of saving water resources, and thus greatly reduce the production cost of corrugated cardboard.
[0007] As a preferred solution of the present utility model, an installation groove is provided at the lower end of the vertical air pipe. The notch of the installation groove is opened on the front side surface of the vertical air pipe. The atomizing nozzle is detachably installed in the corresponding installation groove and is in sealed contact with the notch of the installation groove. This facilitates the installation and disassembly of the atomizing nozzle and makes it more convenient to clean.
[0008] As a preferred solution of the present utility model, the spraying mechanism includes at least two vertical air pipes arranged in sequence from left to right; correspondingly, the number of the atomizing nozzles is also set to at least two. The number of the atomizing nozzles is the same as that of the vertical air pipes and they correspond one by one. The atomizing nozzles are installed at the lower ends of the corresponding vertical air pipes. The installation positions and the number of the vertical air pipes and the atomizing nozzles can be determined according to the different width dimensions of the parts of the corrugated cardboard to be processed. Thus, the spray humidification area of the spraying mechanism can be increased by adding vertical air pipes and atomizing nozzles to meet the requirements of different width dimensions of the parts of the corrugated cardboard to be processed.
[0009] As a preferred solution of the present utility model, the upper pressing mechanism further includes two adjusting seats arranged side by side left and right and a spacing adjusting mechanism for driving the distance between the two adjusting seats. The two adjusting seats can be installed on the frame to be movable left and right. The spacing adjusting mechanism is installed on the frame. The two upper pressing mechanisms correspond to the two adjusting seats one by one, and the lifting components of the upper pressing mechanism are installed on the corresponding adjusting seats. With this structure, the distance between the two adjusting seats can be adjusted through the spacing adjusting mechanism, so as to adjust the distance between the two upper pressing mechanisms, which is suitable for pressing and fixing corrugated cardboard with different width dimensions to ensure a good humidification effect on the parts of the corrugated cardboard to be processed.
[0010] As a further preferred solution of the utility model, the lifting assembly includes a rodless cylinder and a lifting plate. The cylinder body of the rodless cylinder is installed on the adjustment seat and is in an up-and-down direction. The upper part of the lifting plate is installed on the slider of the rodless cylinder; the upper pressure block is installed at the lower end of the lifting plate. With this structure, the lifting plate and the upper pressure block can be driven to rise or fall to a certain height by the slider of the rodless cylinder.

The vertical air pipe 32 is installed on the frame 1 and is directly above the middle of the conveying surface 201 of the conveying mechanism 2. The upper end of the vertical air pipe 32 is communicated with the water vapor outlet of the water vapor generating device 31. The atomizing nozzle 33 is installed at the lower end of the vertical air pipe 32. The inner cavity of the atomizing nozzle 33 is communicated with the vertical air pipe 32. The atomizing nozzle 33 has a plurality of water spraying ports 331, and each water spraying port 331 faces the upper part of the middle of the conveying surface 201 of the conveying mechanism 2; the two upper pressing mechanisms 4 are arranged side by side on the left and right sides of the spray mechanism 3. The upper pressing mechanism 4 includes two adjusting seats 41 arranged side by side left and right, a spacing adjusting mechanism 42 for driving the spacing between the two adjusting seats 41, an upper pressing block 43, and a lifting assembly 44 for driving the upper pressing block 43 to lift and lower.

The upper pressing block 43 is directly above the conveying surface 201 of the conveying mechanism 2.
[0019] In this embodiment, an installation groove 321 is provided at the lower end of the vertical air pipe 32. The notch of the installation groove 321 is opened on the front side surface of the vertical air pipe 32. The atomizing nozzle 33 is detachably installed in the corresponding installation groove 321 and is in sealed contact with the notch of the installation groove 321. This facilitates the installation and disassembly of the atomizing nozzle 33 and makes it more convenient to clean.
[0020] In this embodiment, the spray mechanism 3 includes two vertical air pipes 32 arranged side by side left and right; correspondingly, the number of atomizing nozzles 33 is also set to two. The two atomizing nozzles 33 correspond to the two vertical air pipes 32 one by one, and the atomizing nozzles 33 are installed at the lower ends of the corresponding vertical air pipes 32. This can increase the spray humidifying area of the spray mechanism 3 to meet the humidifying requirements for a larger width dimension of the to-be-processed part of the corrugated cardboard.
[0021] In this embodiment, the spacing adjustment mechanism 42 includes two guide rods 421, an adjustment screw 422, and an adjustment motor (not shown in the figure).

When it is necessary to adjust the distance between the two adjustment seats 41 through the spacing adjustment mechanism 42, the adjustment motor can be used to drive the adjustment screw 422 to rotate forward or backward. By utilizing the meshing relationship between the left screw section 4221 and right screw section 4222 of the adjustment screw 422 and the left screw hole and right screw hole, the two adjustment seats 41 are driven to move towards or away from each other along the guide rods 421, thereby realizing the adjustment of the distance between the two adjustment seats 41 and the upper pressing mechanism 4 thereon.

[0023] The working principle of this humidifying and spraying device is briefly described as follows:
[0024] According to the width dimension of the corrugated cardboard that needs to be humidified, the spacing between the two adjustment seats 41 can be adjusted through the spacing adjustment mechanism 42, so as to adjust the distance between the two upper pressing mechanisms 4, making the positions of the two upper pressing mechanisms 4 corresponding to the two side parts of the corrugated cardboard.
[0025] During operation, the conveying mechanism 2 drives the corrugated board to move forward to backward in an intermittent manner through its conveying surface 201, passing right below the spraying mechanism 3 and the two upper pressing mechanisms 4. During this process, the parts of the upper surface of the corrugated board to be processed for grooving and molding gradually move past right below each atomizing nozzle 33; during the process when the conveying mechanism 2 pauses the movement of the corrugated board, first, the lifting components 44 of the two upper pressing mechanisms 4 drive the upper pressing blocks 43 to move downward, pressing both sides of the corrugated board tightly on the conveying surface 201 of the conveying mechanism 2, then the steam generating device 31 of the spraying mechanism 3 conveys steam to each vertical air pipe 32, and then sprays it through each water spraying port 331 of the atomizing nozzle 33 onto the parts of the corrugated board to be processed, achieving sufficient spray humidification of the parts to be processed at this position of the corrugated board; subsequently, the spraying mechanism 3 stops working, and the lifting components 44 of the two upper pressing mechanisms 4 drive the upper pressing blocks 43 to move upward and reset, preparing for the next spray humidification of the lower position of the parts to be processed of the corrugated board; by repeating the above process, this humidifying spray device can achieve sufficient humidification of the parts to be processed of the corrugated board, improve the humidification effect, effectively reduce the waste of water resources, achieve the purpose of saving water resources, and thus greatly reduce the production cost of the corrugated board.
