Description

Technical Field

[0001] This utility model relates to the field of adhesive application technology for fully biodegradable sanitary napkins, and in particular to an adhesive application device for fully biodegradable sanitary napkins that can be washed away. Background Technology

[0002] Sanitary napkins are hygiene products used by women during their menstrual period. They typically consist of a surface layer, an absorbent layer, and a backing layer. The surface layer is usually made of soft, breathable material to maintain comfort when in contact with the skin. The absorbent layer is the core part, made of highly absorbent material to quickly absorb menstrual blood and prevent side leakage. The backing layer is responsible for preventing leakage. Sanitary napkins come in various types, such as daytime, nighttime, and extra-long nighttime, to meet different needs. Daytime napkins are thinner and lighter, suitable for use during daytime activities; nighttime napkins are longer and wider to handle the flow during sleep; and extra-long nighttime napkins provide more comprehensive protection at night. In modern life, sanitary napkins provide women with convenient, hygienic, and comfortable care during their menstrual period.

[0003] In the production process of sanitary napkins, adhesive is usually applied to the back of the napkin to facilitate adhesion during use. However, existing adhesive application devices may misalign during the application process due to the sanitary napkin shifting, causing the actual adhesive application position to accidentally contact the intended adhesive application position, which in turn affects the yield rate of the production. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a washable, fully biodegradable adhesive applicator for sanitary napkins.

[0005] This utility model is achieved by the following technical solution: a washable fully biodegradable sanitary napkin adhesive application device, comprising a pressing mechanism, a conveying mechanism and a main body mechanism, wherein the pressing mechanism is located inside the main body mechanism and the conveying mechanism is located on the upper surface of the main body mechanism;

[0006] The clamping mechanism includes a clamping plate, a connecting rod rotatably connected to the top of the clamping plate, a slider rotatably connected to the top of the connecting rod, and an adhesive hole in the middle of the clamping plate.

[0007] Through the above technical solution, the pressing plate is rotatably connected to the connecting rod, and the connecting rod is rotatably connected to the slider. Thus, the pressing plate and the slider can be connected through the connecting rod. When the slider moves, the pressing plate can be moved up and down through the connecting rod, thereby fixing the sanitary napkin to be glued. This can prevent the sanitary napkin from moving during the glue application process and causing the glue to deviate. By opening glue holes on the outer wall of the pressing plate, the predetermined glue application position can be reserved through the glue holes, so that the equipment can complete the glue application operation smoothly. In addition, the other parts can be blocked by the pressing plate, thereby preventing glue from splashing during the glue application process, which would affect the subsequent finished product effect, and thus increasing the yield rate of the equipment production process.

[0008] As a further improvement to the above solution, the inner wall of the slider is threaded with a two-way lead screw, the top end of the two-way lead screw is fixedly connected to a driven wheel, the outer wall of the driven wheel is sleeved with a transmission belt, the end of the transmission belt away from the driven wheel is sleeved with a driving wheel, and the middle of the driving wheel is fixedly connected to a motor.

[0009] Through the above technical solution, the output end of the motor is fixedly connected to the drive wheel, the end of the transmission belt is sleeved with the drive wheel, and the top is sleeved with the driven wheel. The driven wheel is fixedly connected to the bidirectional lead screw. When the motor is driven by an external 380V AC power source, its kinetic energy can be transmitted through the drive wheel, transmission belt, and driven wheel, thereby causing the bidirectional lead screw to rotate. When the bidirectional lead screw rotates, it can drive the slider that is threaded to the outer wall to move. When the slider moves, it can drive the pressure plate to move up and down through the connecting rod, thereby increasing the linkage of the overall equipment.

[0010] As a further improvement to the above solution, a guide rod is slidably connected to the inner wall of the clamping plate.

[0011] With the above technical solution, the pressure plate is slidably connected to the guide rod. By setting the pressure plate to slide on the outer wall of the guide rod, the movement of the pressure plate can be guided by the guide rod, and the range of movement can be limited, thereby increasing the stability of the pressure plate during movement.

[0012] As a further improvement to the above solution, the conveying mechanism includes a second motor, the output end of which is fixedly connected to a transmission roller, and a conveyor belt is sleeved on the outer wall of the transmission roller.

[0013] Through the above technical solution, the output end of the second motor is fixedly connected to the transmission roller. When the second motor is driven by the external 380V AC power, the second motor can drive the transmission roller to rotate. The outer wall of the transmission roller is fitted with a conveyor belt. When the transmission roller rotates, the friction between the other conveyor belts will drive the conveyor belt to move in a cycle, thereby automatically driving the sanitary napkin into the equipment to complete the gluing process, thus increasing the overall automation level of the equipment.

[0014] As a further improvement to the above solution, the top end of the transmission roller is rotatably connected to a conveyor belt housing, the upper surface of the conveyor belt housing is fixedly connected to a mounting base, and the inner wall of the mounting base is slidably connected to a limit frame.

[0015] Through the above technical solution, the transmission roller is rotatably connected to the conveyor belt shell, the conveyor belt shell is fixedly connected to the mounting base, and the mounting base is slidably connected to the limiting frame. By setting symmetrical limiting frames on both sides of the outer wall of the conveyor belt shell, the conveying of sanitary napkins can be limited by the limiting frames, preventing the sanitary napkins from shifting or falling during the conveying process, so that the sanitary napkins can smoothly enter the equipment.

[0016] As a further improvement to the above solution, the main structure includes a main base plate, and a main base frame is fixedly connected to the bottom of the main base plate.

[0017] Through the above technical solution, the main base plate is fixedly connected to the main base frame. By setting multiple main base frames at the bottom of the main base plate to support the main base plate, the overall stability of the equipment can be increased.

[0018] As a further improvement to the above solution, a main body shell is fixedly connected to the upper surface of the main body base plate, a fixed bracket is fixedly connected to the inner wall of the main body shell, and a glue spraying head is fixedly connected to the middle of the fixed bracket.

[0019] Through the above technical solution, the main body base plate is fixedly connected to the main body shell, the main body shell is fixedly connected to the fixed bracket, and a glue spray head is fixedly connected to the middle of the fixed bracket. When the sanitary ware enters the equipment, it can be automatically glued through the glue spray head.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] This invention features a motor whose output end is fixedly connected to a drive wheel. The drive wheel is sleeved at the end of a transmission belt, and a driven wheel is sleeved at the top. A bidirectional lead screw is fixedly connected to the driven wheel. When the motor is driven by an external 380V AC power source, its kinetic energy is transmitted through the drive wheel, transmission belt, and driven wheel, causing the bidirectional lead screw to rotate. This rotation drives a slider threaded to the outer wall of the motor. The slider's movement, in turn, moves a pressing plate up and down via a connecting rod, thus securing the sanitary napkin to be glued. This prevents the napkin from shifting during the glue application process, thus avoiding deviation. A glue-applying hole is provided on the outer wall of the pressing plate to allow for pre-planning of the glue application position, facilitating smooth application and preventing glue splattering, which could negatively impact the final product and improve yield. A guide rod is slidably connected to the pressing plate, guiding its movement and limiting its range to increase stability.

[0022] This invention features a transmission roller fixedly connected to the output end of a second motor. When the second motor is driven by an external 380V AC power source, it rotates the transmission roller. A conveyor belt is fitted onto the outer wall of the transmission roller. As the transmission roller rotates, friction causes the conveyor belt to move in a circular motion, which in turn allows the sanitary napkin to automatically enter the equipment for gluing. The transmission roller is rotatably connected to the outer shell of the conveyor belt, which is fixedly connected to a mounting base. A limiting frame is slidably connected to the mounting base. By setting symmetrical limiting frames on both sides of the outer wall of the conveyor belt shell, the sanitary napkin can be conveyed and limited to prevent it from shifting or falling, thus ensuring its smooth entry into the equipment.

[0040] The implementation principle of the washable fully biodegradable sanitary napkin adhesive device in this application embodiment is as follows: The output end of a motor 109 is fixedly connected to a drive wheel 108. The end of a transmission belt 107 is sleeved with the drive wheel 108, and the top end is sleeved with a driven wheel 106. The driven wheel 106 is fixedly connected to a bidirectional lead screw 105. When an external 380V AC power source drives the motor 109 to operate, its kinetic energy can be transmitted through the drive wheel 108, transmission belt 107, and driven wheel 106, thereby enabling the bidirectional lead screw 105 to... 05 rotates, and when the bidirectional lead screw 105 rotates, it can drive the slider 103, which is threaded to the outer wall, to move.
