Description

Technical Field

[0001] The invention relates to the technical field of paper product processing, and in particular to an adjustable paper product humidifying device. Background Art

[0002] During the production and processing of paper products, dry paper tends to become brittle, which makes it easy to break during processing. Humidification can increase the water content of paper, making it softer and more flexible, thereby reducing the risk of breakage. For example, before printing, humidifying the paper can improve its flexibility and flatness, reduce static electricity, and ensure uniform adhesion and absorption of ink. When making packaging materials such as paper boxes and paper bags, humidifying the creases can make the paper easier to fold and shape, while reducing the risk of breakage.

[0003] It may be easier to humidify the entire paper, but it is more difficult to humidify only the creases, because it is necessary to ensure that the moisture content of the paper after humidification is within an appropriate range. Too high a moisture content will cause the paper to be too soft, easy to deform or moldy, while too low a moisture content will not achieve the required flexibility and plasticity. Usually, local spraying or a small nozzle is used to directly humidify the creases. This method is not easy to control the amount of water sprayed, which may cause the creases of paper products to be locally too wet or too dry, affecting the folding and forming effects, increasing the scrap rate, and reducing production efficiency. Summary of the invention

[0004] In order to overcome the shortcoming that it is difficult to control the amount of water sprayed when humidifying the folds of paper products, the present invention provides an adjustable paper product humidifying device.

[0007] Furthermore, the fixed guide rail is provided with an oblique groove, and the fixed guide rail is slidably connected to the opening and closing plate through the oblique groove.

[0008] Furthermore, the opening and closing plate is provided with a triangular through hole.

[0009] Furthermore, the rotating member is configured as a rotating rod, the rotating rod is fixedly connected to the corresponding rotating nozzle, and the rotating rod is movably connected to the connecting plate via a movable groove.

[0010] Furthermore, it also includes a water tank, which is fixedly connected to the connecting frame, and the second sliding frame on one side is fixedly connected with a water outlet pipe, the water outlet pipe passes through the first sliding wheel, the water outlet pipe is plugged into the second sliding wheel, the water tank is connected with a hose, and the water outlet pipe is connected with the hose.

[0011] Furthermore, the water outlet pipe is configured as a hard pipe.

[0012] Furthermore, it also includes a limiting sliding rod for limiting the telescopic rod of the cylinder, and the limiting sliding rod is slidably connected to the connecting frame.

[0013] Furthermore, the limiting sliding rod is fixedly connected to the telescopic rod of the cylinder.

[0016] 2. The present invention rolls the first sliding wheel and the second sliding wheel back and forth along the portion of the paper product to be folded, thereby pressing a crease on the paper product.

The present invention can push the paper product forward and backward by precisely adjusting the position of the slider by moving it forward and backward, so that the paper product moves to the rear side and contacts the adjusted slider, thereby precisely translating and fine-tuning the position of the crease humidification.

DETAILED DESCRIPTION

[0035] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0036] Embodiment 1: An adjustable paper product humidifying device, such as Figure 1-Figure 6As shown, it includes a frame 101, the upper part of the frame 101 is slidably connected to a first sliding frame 102 along the front-to-back direction, the first sliding frame 102 is fixedly connected to a linear motor 103, the first sliding frame 102 is slidably connected to a connecting frame 104 along the left-to-right direction, the connecting frame 104 is fixedly connected to the output end of the linear motor 103, the bottom of the connecting frame 104 is fixedly connected to a cylinder 1041, the telescopic end of the cylinder 1041 is fixedly connected to a connecting plate 105, the connecting plate 105 is slidably connected to a second sliding frame 106 symmetrically distributed along the front and back of the connecting plate 105, the connecting plate 105 is rotatably connected to a bidirectional screw 107 symmetrically distributed along the left and right of the connecting plate 105, the second sliding frame 106 is threadedly connected to the bidirectional screw 107, and the left part of the second sliding frame 106 is fixedly connected to There is a connecting pipe 108, which is slidably connected to the connecting plate 105. A fixed frame 109 is fixedly connected to the lower left side of the second sliding frame 106. The connecting pipe 108 is fixedly connected to the adjacent fixed frame 109 on the same side. A rotating nozzle 110 is rotatably connected to the fixed frame 109. The rotating nozzle 110 is rotatably connected to the connecting pipe 108 adjacent to the same side. The fixed frame 109 covers part of the hole position of the rotating nozzle 110. The lower right side of the second sliding frame 106 on the front side is rotatably connected to the first sliding wheel 111, and the lower right side of the second sliding frame 106 on the rear side is rotatably connected to the second sliding wheel 112. The first sliding wheel 111 and the second sliding wheel 112 are slidably connected to each other, and the outer peripheries of the first sliding wheel 111 and the second sliding wheel 112 are both provided with a plurality of convex strips.

[0037] like Figure 7 and Figure 8 As shown, it also includes a fixed guide rail 201 symmetrically distributed along the front and back of the connecting plate 105, the fixed guide rail 201 is fixedly connected to the upper left side of the connecting plate 105, the fixed guide rail 201 is provided with an oblique groove, the upper part of the connecting pipe 108 is slidably connected with an opening and closing plate 202 along the left and right directions, the fixed guide rail 201 is slidably connected to the opening and closing plate 202 adjacent to the same side through the oblique groove, the opening and closing plate 202 is provided with a triangular through hole, and a rotating rod 203 is fixedly connected to the right side of the rotating nozzle 110, and the rotating rod 203 is movably connected to the connecting plate 105 through a movable groove.

[0038] First, lay the paper product to be humidified on the lower part of the frame 101, connect the connecting pipe 108 to an external water pump, and then start the cylinder 1041. The telescopic end of the cylinder 1041 extends to drive the connecting plate 105, the second sliding frame 106, the bidirectional screw 107, the connecting pipe 108, the fixed frame 109, the rotating nozzle 110, the first sliding wheel 111 and the second sliding wheel 112 to move downward as a whole, so that the first sliding wheel 111 and the second sliding wheel 112 are in contact with the top surface of the paper product, and then push the first sliding frame 102 back and forth to move the first sliding wheel 111 and the second sliding wheel 112 to the position where the paper product is to be bent, and then start the external water pump, the water pump transports water to the connecting pipe 108, and then obliquely sprays water onto the paper product through the nozzles of the two opposite rotating nozzles 110, and at the same time starts the linear motor 103, and the linear motor 103 drives the connecting frame 104 to move along the first A sliding frame 102 slides back and forth left and right, thereby driving the connecting plate 105, the second sliding frame 106, the bidirectional screw 107, the connecting pipe 108, the fixed frame 109, the rotating nozzle 110, the first sliding wheel 111 and the second sliding wheel 112 to move back and forth left and right as a whole. The rotating nozzle 110 sprays a trace of water back and forth left and right along a straight line on the fold line of the paper product. By slightly humidifying the paper product, the paper product can be easier to fold and shape, while reducing the risk of rupture. The first sliding wheel 111 and the second sliding wheel 112 roll back and forth left and right along the part of the paper product to be folded, thereby pressing a crease on the paper product. At the same time, the first sliding wheel 111 and the second sliding wheel 112 can also slightly squeeze the crease after slight humidification, forcing the water to penetrate into the inside of the paper product faster and more evenly, avoiding uneven water penetration causing the crease of the paper product to be locally too wet or too dry.

[0039] In the above process, since the fixed frame 109 covers part of the holes of the rotating nozzle 110, the initial water spraying range is small. The water spraying range can be fine-tuned later as needed. The specific operation is as follows: rotate the bidirectional screw 107 to make the two second sliding frames 106 slide away from each other, so that the two connecting pipes 108 slide along the connecting plate 105 away from each other, and then drive the two fixed frames 109 to move away from each other, and then drive the two rotating nozzles 110 to move away from each other. Under the limiting effect of the connecting plate 105 on the rotating rod 203, the rotating rod 203 drives the rotating nozzle 110 to rotate relative to the fixed frame 109, so that the covered holes of the rotating nozzle 110 are gradually exposed to expand the water spraying range. When the water spraying range needs to be reduced, the bidirectional screw 107 can be rotated in the opposite direction.

[0040] While adjusting the water spraying range, the first sliding wheel 111 and the second sliding wheel 112 will respectively follow the two connecting plates 105 to move synchronously, so that the first sliding wheel 111 and the second sliding wheel 112 are close to or away from each other, so that the rolling width of the first sliding wheel 111 and the second sliding wheel 112 is automatically adapted to the water spraying range.

[0041] While adjusting the water spray range, the two opening and closing plates 202 respectively follow the two connecting pipes 108 to move synchronously, so that the two opening and closing plates 202 are close to or away from each other. Under the guidance of the fixed guide rail 201, the two opening and closing plates 202 will also move to the left when they are away from each other. At this time, the part of the through hole of the opening and closing plate 202 communicating with the connecting pipe 108 increases. When the two opening and closing plates 202 are close to each other, they will also move to the right. At this time, the part of the through hole of the opening and closing plate 202 communicating with the connecting pipe 108 decreases, so that the water spray amount and the water spray range are automatically adapted.

[0042] In summary, the present invention can adjust the water spray range, the rolling width, and the water spray volume by rotating the bidirectional screw 107, thereby achieving the effect of "one adjustment and three adjustments", and the three are in a mutually adaptive relationship.

[0043] like Figures 9 to 11 As shown, a water tank 301 is also included. The water tank 301 is fixedly connected to the front side of the connecting frame 104. The second sliding frame 106 on the front side is fixedly connected with a water outlet pipe 302. The water outlet pipe 302 is set as a hard pipe. The water outlet pipe 302 passes through the first sliding wheel 111. The water outlet pipe 302 is plugged into the second sliding wheel 112. The bottom of the water tank 301 is connected with a hose 303, and the water outlet pipe 302 is connected to the hose 303.

[0044] The increase in the rolling width may cause the rotating nozzle 110 to be unable to spray the middle part. At this time, the middle part needs to be supplemented with humidification. Specifically, when the rolling width of the first sliding wheel 111 and the second sliding wheel 112 increases to the point where the water outlet pipe 302 is separated from the second sliding wheel 112, the water outlet pipe 302 is no longer blocked, and the water in the water tank 301 flows out to the middle part of the fold of the paper product through the hose 303 and the water outlet pipe 302 in turn. When the rolling width of the first sliding wheel 111 and the second sliding wheel 112 is reduced to the point where the water outlet pipe 302 is inserted into the second sliding wheel 112, the water outlet pipe 302 is blocked and stops discharging water.

[0045] like Figure 2As shown, it also includes a limiting slide bar 401 for limiting the telescopic rod of the cylinder 1041. The limiting slide bar 401 is slidably connected to the connecting frame 104, and the limiting slide bar 401 is fixedly connected to the telescopic rod of the cylinder 1041, so that the telescopic rod of the cylinder 1041 can only move up and down with the limiting slide bar 401, preventing the telescopic rod of the cylinder 1041 from rotating freely, avoiding driving the connecting plate 105 to rotate, thereby avoiding the water spraying path of the rotating sprinkler 110 to be affected, and also avoiding the rolling path of the first sliding wheel 111 and the second sliding wheel 112 to be affected.

[0046] like Figure 1 , Fig.12 and Fig.13 As shown, it also includes a slider 502, which is slidably connected to the frame 101. The slider 502 is threadedly connected to a one-way screw 503, which contacts the frame 101. The frame 101 is engraved with scale teeth 501, and the slider 502 points to the scale teeth 501. First, loosen the one-way screw 503, and then move the slider 502 back and forth according to the scale teeth 501 to accurately adjust the position of the slider 502, so that the paper product can be pushed back and forth, so that the paper product moves to the rear side and contacts the adjusted slider 502. In this way, the position of the crease humidification can be accurately adjusted by translation.

[0047] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
