Abstract
Description
Technical Field
[0001] This application relates to the field of cardboard box production technology, and in particular to a water spraying device for producing cardboard boxes. Background Technology
[0002] In the existing three-dimensional cardboard box production process, the cardboard needs to be creasing with a creasing machine to form crease lines before being folded into a box. If the cardboard is too dry, it is not only prone to warping at the edges and reduced fiber flexibility, but it is also prone to bursting during the folding process, directly affecting the quality of the box and increasing the scrap rate.
[0003] Currently, in the existing cardboard box production process, water is typically sprayed onto the boxes after creasing to prevent subsequent creasing bursts. However, the uniformity of water spraying in existing cardboard box spraying devices needs improvement. Some areas of the cardboard may have excessive moisture, increasing the difficulty of subsequent cardboard processing. Furthermore, existing spraying devices can only cover the horizontal surface of the cardboard, leaving the sides untreated or unevenly covered, which increases the risk of delamination at the cardboard edges and reduces the overall strength of the box. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a water spraying device for producing cardboard boxes. The technical problems it solves are: existing water spraying devices suffer from uneven spraying leading to localized over-wetting, and ineffective coverage of the cardboard sides, causing difficulties in subsequent operations and the risk of edge delamination. To solve these problems, the technical solution adopted by this utility model is:
[0005] A water spraying device for producing cardboard boxes, comprising:
[0006] The frame contains a belt conveyor.
[0007] Mounting bracket, which is fixedly connected to the two end faces of the frame;
[0008] The first water spray assembly is fixedly connected to the mounting bracket.
[0009] Connecting plates are fixedly installed on the upper surfaces of both sides of the frame and are fixedly connected to the mounting bracket.
[0010] The second water spray assembly includes an ultrasonic nozzle, a rotating shaft, and a drive mechanism. The drive mechanism is fixedly mounted on the upper surface of the connecting plate and is connected to the rotating shaft. The rotating shaft is rotatably connected to the connecting plate, and the ultrasonic nozzle is fixedly connected to the rotating shaft.
[0011] Water supply components are located on one side of the frame.
[0012] Furthermore, the mounting frame includes vertical uprights and horizontal connecting columns. The horizontal connecting columns are fixedly connected to the two vertical uprights. The vertical uprights are connected to the side end face of the frame in a fixed structure. The horizontal connecting columns are hollow.
[0013] Furthermore, the first water spray assembly includes a connecting sleeve and a rotary nozzle, the rotary nozzle being fixedly connected to the connecting sleeve, and the connecting sleeve being fixedly connected to a transverse connecting column.
[0014] Furthermore, the drive mechanism includes a cylinder, a rack, and a gear. The middle part of the gear is fixedly connected to the rotating shaft, and the gear meshes with the rack. A support plate is fixedly connected to the other end face of the rack. The support plate is slidably connected to the connecting plate. One end face of the support plate is fixedly connected to the output end of the cylinder. The cylinder is fixedly mounted on the upper end face of the connecting plate in a fixed structure.
[0015] Furthermore, the water supply components include a water tank and a water pipe, with one end of the water pipe connected to the water tank and the other end connected to a rotary nozzle and an ultrasonic nozzle, respectively.
[0016] Furthermore, a photoelectric sensor for detecting the position of the cardboard is fixedly installed on the inner end face of the vertical plate; a water inlet valve is installed on the water pipe, and the water inlet valve is connected to the photoelectric sensor signal.
[0017] Furthermore, protective plates are fixedly installed on the four side ends and the top of the connecting plate. The upper protective plate has holes for the rotating shaft to pass through, and the protective plate close to the vertical plate is fixedly connected to the vertical plate.
[0018] The beneficial effects of this utility model are as follows: through the coordinated configuration of the first water spraying component and the second water spraying component, a three-dimensional spraying system is realized. The first water spraying component covers the horizontal surface of the cardboard, effectively suppressing the bursting defects caused by fiber brittle fracture. The second water spraying component sprays water on the side of the cardboard, so that the side boundary of the cardboard obtains a gradient wetting effect, effectively reducing the risk of delamination at the edge of the cardboard and enhancing the overall strength of the cardboard.
[0019] Through the gear and rack mechanism, the drive shaft rotates, which in turn drives the ultrasonic nozzle to rotate at a certain angle. This structure allows the sides of the cardboard to receive a uniform amount of water, making it compatible with different cardboard sizes and significantly enhancing its practicality.

The specific implementation scheme of this utility model is as follows:
[0027] A water spraying device for producing cardboard boxes includes a frame 1, a belt conveyor 2 disposed within the frame 1, mounting brackets 3 fixed to both end faces of the frame 1, a first water spraying assembly 4 fixedly mounted on the mounting brackets 3, connecting plates 5 fixedly mounted to the upper end faces of both sides of the frame 1, the connecting plates 5 being fixedly connected to the mounting brackets 3, a second water spraying assembly 6 disposed on the upper end face of the connecting plates 5, the second water spraying assembly 6 including an ultrasonic nozzle 61, a rotating shaft 62, and a drive mechanism 63, the drive mechanism 63 being fixedly mounted on the upper end face of the connecting plates 5, and the drive mechanism 63 being connected to the rotating shaft 62. 62 is rotatably connected to the connecting plate 5, and the ultrasonic nozzle 61 is fixedly connected to the rotating shaft 62. A water supply component 7 is provided on one side of the frame 1. Through the coordinated configuration of the first water spraying component 4 and the second water spraying component 6, a three-dimensional spraying system is realized. The first water spraying component 4 sprays water on the horizontal plane of the cardboard 13, effectively suppressing the bursting defects caused by fiber brittle fracture. The second water spraying component 6 sprays water on the side of the cardboard, so that the side boundary of the cardboard obtains a gradient wetting effect, effectively reducing the risk of delamination at the edge of the cardboard and enhancing the overall strength of the cardboard.
[0028] It should be noted that the mounting frame 3 includes a vertical plate 31 and a horizontal connecting column 32. The horizontal connecting column 32 is fixedly connected to the two vertical plates 31. The vertical plates 31 are connected to the side end face of the frame 1 in a fixed structure. The horizontal connecting column 32 is hollow. This structure is mainly used to install the first water spray assembly 4. The hollow horizontal connecting column 32 is used to pass through the water pipe 72 and connect it to the rotary nozzle 42.
[0029] It should be noted that the first water spraying assembly 4 includes a connecting sleeve 41 and a rotary nozzle 42. The rotary nozzle 42 is fixedly connected to the connecting sleeve 41, and the connecting sleeve 41 is fixedly connected to the transverse connecting column 32. This structure enables uniform spraying to cover the horizontal surface of the cardboard, effectively suppressing the bursting defects caused by fiber brittle fracture.
[0030] It should be explained that the drive mechanism 63 includes a cylinder 631, a rack 632, and a gear 633. The middle part of the gear 633 is fixedly connected to the rotating shaft 62, and the gear 633 meshes with the rack 632. A support plate 8 is fixedly connected to the other end face of the rack 632. The support plate 8 is slidably connected to the connecting plate 5. One end face of the support plate 8 is fixedly connected to the output end of the cylinder 631. The cylinder 631 is fixedly mounted on the upper end face of the connecting plate 5. The cylinder 631 drives the support plate 8 to move along the connecting plate 5. The movement of the support plate 8 will drive the rack 632 to move. The movement of the rack 632 will drive the gear 633 to rotate. The rotation of the gear 633 will drive the rotating shaft 62 to rotate, which in turn will drive the ultrasonic nozzle 61 to rotate synchronously, so as to spray water evenly to the side edge of the cardboard.
[0031] It should be noted that the water supply component 7 includes a water tank 71 and a water pipe 72. One end of the water pipe 72 is connected to the water tank 71, and the other end of the water pipe 72 is connected to the rotary nozzle 42 and the ultrasonic nozzle 61, respectively.
[0032] Furthermore, a photoelectric sensor 9 for detecting the position of the cardboard is fixedly installed on the inner end face of the vertical plate 31; a water inlet valve 10 is installed on the water pipe 72, and the water inlet valve 10 is connected to the photoelectric sensor 9; the photoelectric sensor 9 is used to detect the position of the cardboard and sends the signal to the water inlet valve 10 in real time. The water inlet valve 10 controls whether to supply water according to the signal to avoid water waste caused by continuous water spraying.
[0033] It should be noted that protective plates 11 are fixedly installed on the four side ends and the top of the connecting plate 5. The upper protective plate 11 has a hole for the rotating shaft 62 to pass through. The protective plate 11 close to the vertical plate 31 is fixedly connected to the vertical plate 31. This structure is mainly used to protect the drive mechanism 63 and extend its service life.
[0034] The working principle and process of this utility model are as follows:
[0035] The photoelectric sensor 9 monitors the position of the cardboard in real time. When the cardboard is output from the crimping machine 12 (existing technology) to the area below the mounting frame 3, the photoelectric sensor 9 transmits a signal to the water inlet valve 10. The water inlet valve 10 opens to allow water to flow through the water pipe 72 to the rotary nozzle 42 and the ultrasonic nozzle 61. The rotary nozzle 42 converts the water flow into a water mist and sprays it onto the horizontal surface of the cardboard. The ultrasonic nozzle 61 converts the water flow into a water mist and sprays it onto the side edge of the cardboard. At the same time, the cylinder 631 is activated, pushing the support plate 8 to reciprocate along the connecting plate 5. The rack 632, which is fixedly connected to the support plate 8, moves with the support plate 8. The movement of the rack 632 drives the gear 633 to rotate. The rotation of the gear 633 drives the rotating shaft 62 to rotate. The ultrasonic nozzle 61, which is fixedly connected to the rotating shaft 62, rotates with the rotating shaft 62, thus achieving uniform spraying of water onto the edge of the cardboard.
