Abstract
Description
Technical Field
[0001] This utility model relates to the field of material changing technology, and in particular to a rotary material changing device for hygiene products. Background Technology
[0002] Hygiene products refer to disposable daily necessities that come into direct contact with the human body, primarily for achieving physiological hygiene or antibacterial / bacteriostatic functions. Typical categories include diapers and wet wipes. In the production process of some hygiene products, sheet-like materials are a key production element. These materials are usually rolled into rolls for easy transportation and warehousing management. In actual production, when a roll of material is exhausted, it needs to be replaced promptly. The core step in replacing rolls is to precisely connect the beginnings of the used roll and the spare roll to ensure production continuity.
[0003] Currently, most manufacturers still rely on manual roll changing, which requires stopping the production line to complete the operation. This not only directly leads to a decrease in production efficiency, but also makes it difficult to achieve high-precision alignment of the material ends during manual overlapping, easily causing overlap deviations that may affect the quality of subsequent products. A few manufacturers use semi-automatic roll changing equipment, but this still requires manual operation by staff to connect the ends of the used roll and the spare roll. The overall operation process lacks convenience, fails to fully reduce labor costs, and is difficult to further improve roll changing efficiency. Utility Model Content
[0004] To address the aforementioned problems, this utility model provides a rotary material changing device for hygiene products.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a rotary material receiving and changing device for hygiene products, comprising a base plate, a mounting seat provided on the base plate, a rotating seat horizontally rotatably mounted on the mounting seat, two mounting rollers rotatably mounted on the rotating seat, a fixed seat provided on the base plate, two parallel swing frames rotatably mounted on the fixed seat, a rotating tube rotatably mounted on the side of the swing frame away from the fixed seat, a fixed rod provided on the swing frame, a connecting plate provided between the two fixed rods, the two sides of the connecting plate being rotatably connected to the two fixed rods respectively, a sliding frame slidably mounted on the connecting plate, and a heating wire for cutting off the material between the two rotating tubes provided on the sliding frame.
[0006] By adopting the above technical solution, the base plate, mounting seat, rotating seat, and two mounting rollers can be used to install the working roll and the spare roll respectively, providing a basic installation structure for subsequent automatic material switching.

The end of the material on the spare roll is attached with tape, until the tape at the end of the material on the working roll and the material on the spare roll connect, thus completing the overlap between the working roll and the spare roll. After the overlap is completed, the sliding frame moves the heating wire to cut the working roll between the two rotating tubes, completing the key step of material switching without manual intervention, adapting to the high-speed production scenarios of hygiene products and reducing labor costs.
[0007] Furthermore, the fixed base includes a fixed block connected to the base plate and two upright plates spaced apart on the top of the fixed block.

[0011] Furthermore, the connecting plate has two sliding holes, the sliding frame includes sliding rods slidably disposed in the sliding holes, and the two sliding rods are provided with a movable plate at the ends away from the rotating shaft. Two mounting plates are provided at intervals on the movable plate, and the two ends of the heating wire are respectively connected to the two mounting plates.
[0012] By adopting the above technical solution, the sliding hole on the connecting plate cooperates with the sliding rod of the sliding frame, so that the sliding frame can slide stably along the sliding hole, thereby driving the heating wire to adjust the horizontal position.
[0013] Furthermore, a drive cylinder is provided on the connecting plate, and the piston rod of the drive cylinder passes through the connecting plate and is connected to the movable plate.
[0014] By adopting the above technical solution, a drive cylinder is set to provide power for the movement of the sliding frame.
[0015] Furthermore, an adjustment motor is provided on one side of one of the upright plates, and the output shaft of the adjustment motor passes through the upright plate and is connected to the end of one of the rotating shafts.
[0016] By adopting the above technical solution, the connection between the motor and the rotating shaft is adjusted, and the rotating shaft is driven to rotate by the motor, thereby causing the swing frame to automatically adjust its angle.
[0017] Furthermore, the mounting base has a horizontally open circular opening, and the rotating base includes a rotating ring rotatably disposed within the circular opening. One end of the rotating ring is provided with a disc, and the disc has two through holes. The mounting roller is rotatably disposed within the through holes.
[0018] By adopting the above technical solution, a rotating ring, a disk, and a through hole are set to ensure the stability of the revolution and rotation of the center line of the mounting roller around the disk.
[0019] Furthermore, a U-shaped seat is provided on the disk corresponding to the through hole, and a drive motor is provided on the U-shaped seat. The output shaft of the drive motor passes through the U-shaped seat and is connected to the mounting roller.
[0020] By adopting the above technical solution, the drive motor can drive the material roll to rotate stably, ensuring that the material roll conveying speed is controllable.
[0021] Furthermore, the mounting base is also horizontally provided with two connecting columns, and the two connecting columns are provided with a fixed plate at the ends away from the mounting base. A rotating motor is horizontally provided on the fixed plate, and a control column is concentrically provided on the disc.

[0022] By adopting the above technical solution, the connecting column, the fixing plate and the rotating motor cooperate, and the rotating motor drives the control column to rotate, thereby driving the disc and the rotating ring to rotate synchronously, so as to realize the replacement of the installation roller.
[0023] Furthermore, a horizontal rod is provided on the side of the disc away from the rotating ring, corresponding to the mounting roller, and a guide tube is rotatably mounted on the horizontal rod.

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0029] like Figure 1-5 As shown in the embodiment of this application, a rotary material receiving and changing device for sanitary products is disclosed, including a base plate 10, a mounting base 11, and a rotating base 20. The mounting base 11 is disposed on the base plate 10, and the rotating base 20 is horizontally rotatably disposed on the mounting base 11. Two mounting rollers 21 are rotatably disposed on the rotating base 20. A fixed base 30 is disposed on the base plate 10, and two parallel swing frames 40 are rotatably disposed on the fixed base 30. A rotating tube 41 is rotatably disposed on the side of the swing frame 40 away from the fixed base 30, and the length direction of the rotating tube 41 is consistent with the length direction of the mounting rollers 21. A fixed rod 42 is disposed on the swing frame 40, and a connecting plate 43 is disposed between the two fixed rods 42. The two sides of the connecting plate 43 are rotatably connected to the two fixed rods 42 respectively. A sliding frame 50 is slidably disposed on the connecting plate 43, and an electric heating wire 51 is disposed on the sliding frame 50 for cutting the material between the two rotating tubes 41. The electric heating wire 51 is heated to a high temperature by an electric current and can cut thermoplastic materials. The base plate 10, mounting seat 11, rotating seat 20, and two mounting rollers 21 work together to install the working roll and the spare roll, providing a basic installation structure for subsequent automatic material switching. The connection between the mounting rollers 21 and the material rolls uses existing technology and will not be described in detail here. The rotation of the rotating seat 20 enables the switching of the working roll and the spare roll, meeting the requirements of automated material switching. The combination of the fixed seat 30, two parallel swing frames 40, and rotating tube 41 allows the rotating tube 41 to be adjusted in position by the rotation of the swing frames 40, so that the rotating tube 41 pushes the material being used on the working roll. The end of the material on the spare roll is attached with tape until the tape at the end of the material on the working roll connects with the tape at the end of the material on the spare roll, thus completing the overlap of the working roll and the spare roll. After the overlap is completed, the sliding frame 50 moves the heating wire 51 to cut the working roll between the two rotating tubes 41, completing the key step of material switching without manual intervention, adapting to the high-speed production of sanitary products and reducing labor costs.
[0030] Specifically, a horizontal bar 26 is installed on the side of the disc 23 away from the rotating ring 22, corresponding to the mounting roller 21. A guide tube 27 is rotatably mounted on the horizontal bar 26. The guide tube 27 on the horizontal bar 26 guides the material during the conveying process, preventing positional deviations caused by material offset during conveying and ensuring that the material is stably conveyed to the rotating tube 41, thus guaranteeing accurate subsequent splicing. The guide tube 27 is rotatable and rotates synchronously with the material conveying, reducing friction between the material and the guide tube 27, preventing material damage due to friction during conveying, and improving material utilization and product quality in hygiene product production.
[0031] In setup, the fixed base 30 includes a fixed block 31 connected to the base plate 10 and two upright plates 32 spaced apart on top of the fixed block 31. The swing frame 40 includes a rotating shaft 44 whose two ends are rotatably connected to the two upright plates 32 respectively. The length direction of the rotating shaft 44 is consistent with the length direction of the mounting roller 21. Two connecting rods 45 are spaced apart on the rotating shaft 44, and the length direction of the connecting rods 45 is perpendicular to the length direction of the rotating shaft 44 to ensure the structural stability of the swing frame 40. A fixed shaft 46 is provided at the ends of the two connecting rods 45 away from the rotating shaft 44. The rotating tube 41 is rotatably sleeved on the fixed shaft 46, and the two ends of the fixed rods 42 are connected to the connecting rods 45 respectively. The rotation of the rotating shaft 44 drives the two connecting rods 45 to rotate, thereby driving the fixed shaft 46 and the rotating tube 41 to rotate.
[0032] In the specific configuration, the connecting plate 43 has two sliding holes. The sliding frame 50 includes sliding rods 52 slidably disposed within the sliding holes. A movable plate 53 is provided at the end of the two sliding rods 52 away from the rotating shaft 44. Two mounting plates 54 are spaced apart on the movable plate 53. The two ends of the heating wire 51 are connected to the two mounting plates 54 respectively. The sliding holes on the connecting plate 43 cooperate with the sliding rods 52 of the sliding frame 50, allowing the sliding frame 50 to slide stably along the sliding holes, thereby driving the heating wire 51 to adjust its horizontal position. This ensures that the heating wire 51 maintains the preset cutting posture during movement, accurately aligning with the material between the two rotating tubes 41, improving cutting efficiency and the flatness of the cut surface. A drive cylinder 47 is provided on the connecting plate 43, with its piston rod passing through the connecting plate 43 and connecting to the movable plate 53. The drive cylinder 47 provides power for the movement of the sliding frame 50, automating the cutting action of the heating wire 51, further reducing human intervention, and meeting the goal of unmanned material changing. The drive cylinder 47 features stable operating speed and controllable stroke, ensuring that the sliding frame 50 moves the heating wire 51 at a preset speed and stroke to cut the material. This avoids problems such as incomplete cutting and material tearing caused by uneven manual operation force or speed, thus improving the quality of material switching. An adjusting motor 33 is installed on one side of one of the upright plates 32. The output shaft of the adjusting motor 33 passes through the upright plate 32 and connects to the end of one of the rotating shafts 44. The adjusting motor 33 drives the rotating shaft 44 to rotate, thereby driving the swing frame 40 to adjust its angle. This achieves automated adjustment of the position of the rotating tube 41 during the material roll overlap process, improving overlap efficiency. The motor drive can control the rotation angle of the rotating shaft 44, making the swing amplitude of the swing frame 40 controllable. This ensures that the rotating tube 41 can accurately drive the material roll to the overlap position, reducing overlap deviation and ensuring the stability of the material switching process.
[0033] The mounting base 11 has a horizontal circular opening. The rotating base 20 includes a rotating ring 22 rotatably disposed within the circular opening. The rotating ring 22 of the rotating base 20 cooperates with the disc 23 and can rotate stably within the circular opening of the mounting base 11, providing stable support for the mounting roller 21. A disc 23 is provided at one end of the rotating ring 22. The disc 23 has two through holes, and the mounting roller 21 is rotatably disposed within the through holes, ensuring the stability of the mounting roller 21's rotation. A U-shaped seat 24 is provided on the disc 23 corresponding to the through holes. A drive motor 25 is provided on the U-shaped seat 24, and the output shaft of the drive motor 25 passes through the U-shaped seat 24 and connects to the mounting roller 21. The mounting roller 21 is mounted on the disc 23 through the through holes, and in cooperation with the drive motor 25 on the U-shaped seat 24, it can drive the material roll to rotate stably, ensuring controllable material roll conveying speed. Two horizontally arranged connecting posts 60 are mounted on the mounting base 11. A fixing plate 61 is shared at the end of the two connecting posts 60 furthest from the mounting base 11. A rotating motor 62 is horizontally mounted on the fixing plate 61, and a control post 28 is concentrically mounted on the disc 23. The output shaft of the rotating motor 62 passes through the fixing plate 61 and connects to the control post 28. The rotating motor 62 drives the control post 28 to rotate, thereby causing the disc 23 and the rotating ring 22 to rotate synchronously, realizing the repositioning of the mounting roller 21. The rotating motor 62 features stable speed and controllable rotation angle, precisely controlling the rotation angle of the disc 23. This ensures that the used roll and the spare roll can be accurately repositioned to the preset position, avoiding subsequent overlap failures due to repositioning deviations and improving the reliability of the material repositioning process.
[0034] An infrared distance sensor is installed on the disc 23 next to the mounting roller 21. When the diameter of the roll being used is large, it blocks the rays emitted by the infrared distance sensor, resulting in a shorter detection distance. When the roll being used is almost empty, the diameter is small, and the rays emitted by the infrared distance sensor are not blocked, causing the value to change and triggering a material change signal. A camera is installed on the mounting base 11, facing the spare roll. Because the color of the tape is different from that of the roll, the camera can determine the position of the tape. A control cabinet is installed on the bottom surface of the base plate 10. The control cabinet contains a controller and an air pump. The controller is used to control various electrical components, and the air pump is used to provide air to the drive cylinder 47 (the infrared distance sensor, camera, and control cabinet are not shown in the figure).
[0035] The operating principle of the rotary material exchange device for hygiene products in this embodiment is as follows: First, in the material exchange preparation stage, when the currently used roll is almost used up, a material exchange signal is triggered. The used roll reduces its conveying speed, while the spare roll starts to rotate, and its linear speed is controlled by the drive motor 25 to keep it synchronized with the used roll. Next is the roll overlap stage, where the adjustment motor 33 drives the rotating shaft 44 to rotate, causing the swing frame 40 and the rotating tube 41 to swing and push the used roll material closer to the spare roll. At the same time, the camera monitors the position of the tape at the end of the spare roll material to ensure that the tape also reaches the overlap point when the swing frame 40 reaches the overlap position, so that the two rolls of material are spliced together by the tape. Then, ... In the old material cutting stage, the drive cylinder 47 on the connecting plate 43 is vented, pushing the sliding frame 50 to move along the sliding hole, driving the heating wire 51 to move the working roll between the two rotating tubes 41. The heating wire 51 is energized and heats up to cut the working roll and ensures that the cut surface is flat. After that, the adjusting motor 33 drives the rotating shaft 44 in the opposite direction, driving the swing frame 40 to swing away from the material roll to the clearance position, making room for the material roll to be repositioned. Immediately afterwards, the rotating motor 62 on the mounting base 11 is started, driving the control column 28, the rotating ring 22 and the disc 23 to rotate synchronously, so that the mounting roller 21 on the disc 23 drives the spare roll and the used roll to rotate 180° to complete the position switch and reposition the material roll.
[0036] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
