Description

Technical Field

[0001] This utility model relates to the field of diaper production and processing technology, specifically a diaper production glue spraying machine. Background Technology

[0002] Disposable diapers are disposable paper products for urinary incontinence, mainly suitable for people with moderate to severe incontinence who are unable to control their urination and defecation. Disposable diapers are usually sold in sheet form, and are connected into a pair of shorts shape by adhesive strips, Velcro, and other fasteners during use.

[0003] For example, patent application number 202320838355.2 discloses a diaper production glue spraying machine. This utility model uses a cleaning component to clean the diaper, reducing the impact of hardened glue on the outer wall of the bottom-mounted electric support cylinder on the fabric conveying. The device is equipped with a cleaning component to ensure cleanliness after spraying. However, this diaper production glue spraying machine does not clean the fabric before spraying. During multiple transfers or conveyings, the fabric will inevitably accumulate dust. If the fabric with dust is directly sprayed with glue, the dust will continue to adhere to the fabric surface, which will not only affect the quality of the glue bonding but also contaminate the raw materials of the diaper.

[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed a glue spraying machine for diaper production. Utility Model Content

[0005] The purpose of this invention is to provide a glue spraying machine for diaper production to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a diaper production glue spraying machine, including a conveyor frame, a support frame fixedly connected to the left side of the upper surface of the conveyor frame, a cleaning roller rotatably connected to the lower side of the inner surface of the support frame, and the interior of the cleaning roller is hollow. Air holes are evenly distributed and penetrated on the surface of the cleaning roller. A filter box is fixedly connected to the front side of the upper surface of the support frame, and an air pump is fixedly connected to the upper surface of the support frame behind the filter box. The air inlet of the air pump is connected to the filter box via a pipe. A conveying pipe is fixedly connected to the front side of the surface of the filter box, and the lower end of the conveying pipe penetrates the support frame and communicates with the interior of the cleaning roller.

[0007] Preferably, an extension plate is fixedly connected to the middle right side of the support frame, and a telescopic rod is fixedly connected through the surface of the extension plate.

[0008] Preferably, a coating head is fixedly connected to the lower end of the telescopic rod, and a spray nozzle is fixedly connected to the lower surface of the coating head.

[0009] Preferably, baffles are fixedly connected to both the left and right sides of the inner surface of the spray nozzle, and tension springs are fixedly connected to the lower surface of the baffles. Movable plates are fixedly connected to the lower ends of the tension springs, and the end of the movable plate away from the center of the spray nozzle is rotatably connected to the inner surface of the spray nozzle.

[0010] Preferably, a material box is fixedly connected to the rear side of the upper surface of the support frame, and the port of the material box is connected to the coating head via a flexible hose.

[0011] Preferably, a sub-frame is fixedly connected to the right side of the upper surface of the conveyor frame, and three pressure rollers are evenly distributed and rotatably connected to the inner surface of the sub-frame.

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

[0013] 1. This utility model, through the arrangement of a cleaning roller, air holes, a filter box, an air pump, and a conveying pipe, allows the fabric to adhere to the cleaning roller during the conveying of the lower layer of diaper fabric. The cleaning roller rotates and rubs against the surface, removing impurities adhering to the fabric surface. At the same time, the air pump draws the dust from the cleaning roller through the air holes via the filter box and conveying pipe, and then flows into the filter box through the conveying pipe. The impurities are stored in the filter box by the filter element inside, preventing secondary re-entrainment. This effectively cleans the fabric before adhesive application, preventing impurities from mixing with the adhesive and affecting the adhesive quality, and ensuring the cleanliness of the entire diaper production process.

[0014] 2. This utility model, through the arrangement of baffles, tension springs, and movable plates, allows the movable plate to rotate downwards during spraying, opening the spray nozzle and enabling the adhesive to be applied smoothly. After the coating work is completed, the adhesive stops being output, meaning that no more pressure is applied to the upper part of the movable plate. Under the action of the tension spring, the movable plate rotates upwards, and the baffle limits the movement, keeping both sides of the movable plate horizontal. This automatically seals the spray nozzle, effectively preventing residual adhesive from dripping and contaminating the machine after the work is completed. Attached Figure Description

[0019] 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.

[0020] like Figures 1-3 As shown, a diaper production glue spraying machine includes a conveyor frame 1. A support frame 2 is fixedly connected to the left side of the upper surface of the conveyor frame 1. A cleaning roller 3 is rotatably connected to the lower side of the inner surface of the support frame 2. The interior of the cleaning roller 3 is hollow. Air holes 4 are evenly distributed and penetrated on the surface of the cleaning roller 3. A filter box 5 is fixedly connected to the front side of the upper surface of the support frame 2. An air pump 6 is fixedly connected to the upper surface of the support frame 2 behind the filter box 5. The air inlet end of the air pump 6 is connected to the filter box 5 via a pipe. A conveying pipe 7 is fixedly connected to the front side of the surface of the filter box 5. The lower rear end of the conveying pipe 7 penetrates the support frame 2 and communicates with the interior of the cleaning roller 3.

[0021] By adopting the above technical solution, when the lower layer of fabric of the diaper is conveyed, the fabric will stick to the cleaning roller 3, and the cleaning roller 3 will rotate and rub on the surface to remove the impurities adhering to the surface of the fabric.

[0022] The air pump 6 draws the dust from the wiping process into the cleaning roller 3 through the air hole 4, passing through the filter box 5 and the delivery pipe 7. The dust then flows through the delivery pipe 7 into the filter box 5, where the impurities are stored by the filter element inside the filter box 5.

[0023] Furthermore, an extension plate 8 is fixedly connected to the middle right side of the surface of the support frame 2, and a telescopic rod 9 is fixedly connected through the surface of the extension plate 8.

[0024] By adopting the above technical solution, the telescopic rod 9 can adjust the height of the spray nozzle, thereby adjusting the spray coverage area.

[0025] Furthermore, a coating head 10 is fixedly connected to the lower end of the telescopic rod 9, and a spray nozzle 11 is fixedly connected to the lower surface of the coating head 10; the coating head 10 has a built-in heating unit to prevent the glue from solidifying and clogging.

[0026] Baffles 12 are fixedly connected to both the left and right sides of the inner surface of the spray nozzle 11, and tension springs 13 are fixedly connected to the lower surface of the baffles 12. Movable plates 14 are fixedly connected to the lower end of the tension springs 13, and one end of the movable plate 14 away from the center of the spray nozzle 11 is rotatably connected to the inner surface of the spray nozzle 11.

[0027] By adopting the above technical solution, the pressure of the glue spray will cause the movable plate 14 to rotate downward and open the spray nozzle 11, so that the glue can be applied normally and smoothly.

[0028] After the coating work is completed, the glue will no longer be dispensed, that is, the upper side of the movable plate 14 will no longer be pressured. Under the action of the tension spring 13, the movable plate 14 will rotate upward and be limited by the baffle 12 to keep the two movable plates 14 horizontal, which can automatically seal the spray nozzle 11 and effectively prevent residual glue from dripping after the work is completed.

[0029] Furthermore, a material box 15 is fixedly connected to the rear side of the upper surface of the support frame 2, and the port of the material box 15 is connected to the coating head 10 via a flexible hose.

[0030] By adopting the above technical solution, the material box 15 is filled with adhesive liquid, which is then supplied to the coating head 10 for adhesive spraying.

[0031] Furthermore, a sub-frame 16 is fixedly connected to the right side of the upper surface of the conveyor frame 1, and three pressure rollers 17 are evenly distributed and rotatably connected to the inner surface of the sub-frame 16.

[0032] By adopting the above technical solution, the pressure roller 17 can press and bond the two layers of upper and lower fabrics that need to be bonded together, and during the pressing process, the adhesive can be more evenly distributed in the middle of the two layers of fabric.

[0033] Working Principle: When using this diaper production glue spraying machine, firstly, during the conveying of the lower layer of diaper fabric, the fabric adheres to the cleaning roller 3. The cleaning roller 3 rotates and rubs against the surface, removing impurities adhering to the fabric surface. Simultaneously, the suction pump 6 draws the dust from the wiping process into the cleaning roller 3 through the air holes 4 via the filter box 5 and the conveying pipe 7. The dust then flows through the conveying pipe 7 into the filter box 5. The filter element inside the filter box 5 prevents impurities from being re-entrained, effectively cleaning the fabric before glue application and preventing impurities from mixing with the glue. Then, the coating head 10 extracts the glue through the material box 15 and sprays it onto the surface of the lower layer of fabric through the spray nozzle 11. During spraying, the glue... The pressure of the water jet causes the movable plate 14 to rotate downwards, opening the spray nozzle 11, thus allowing the glue to be applied smoothly. After the lower layer of fabric is coated with glue, the upper layer of fabric is conveyed from the right side of the extension plate 8. The upper and lower layers of fabric enter the sub-frame 16 together and are then bonded by the pressure roller 17. After the coating work is completed, the glue is no longer output, that is, the upper side of the movable plate 14 is no longer pressured. Under the action of the tension spring 13, the movable plate 14 rotates upwards. The baffle 12 limits the movement, keeping the two movable plates 14 horizontal, which automatically seals the spray nozzle 11 and effectively prevents residual glue from dripping and contaminating the machine after the work is completed. This is the working principle of the glue spraying machine for diaper production.
