Description

Technical Field

[0001] This utility model belongs to the technical field of medical supplies production equipment, and in particular relates to a winding device for the production of gauze bandages. Background Technology

[0002] Currently, in the production of gauze bandages, the gauze bandages are usually wound onto a roll and stored in a roll. Then, according to different production needs, the gauze bandage roll can be unwound and then cut or folded to form different medical products.

[0003] In existing technologies, when using a winding device to wind up gauze bandages, once the gauze bandage roll on the winding device reaches the required specifications, after cutting and fixing the gauze bandage, a new roll needs to be replaced. Specifically, the original roll is first removed from the winding device, and then the new roll is reinstalled on the winding device after the gauze bandage roll is moved using lifting equipment or a forklift. The entire process is time-consuming, especially the time spent moving the gauze bandage roll, which causes excessive downtime of the winding device and affects winding efficiency. Therefore, existing technologies still have shortcomings and deficiencies. Utility Model Content

[0004] The purpose of this invention is to provide a winding device for producing gauze bandages, in order to solve the problems mentioned in the background art.

[0005] The technical solution adopted by this utility model to solve the above problems is as follows:

[0006] A gauze bandage production winding device includes a support platform, above which a horizontally distributed and rotatable bearing platform is installed. Two sets of symmetrically distributed winding mechanisms are installed on both sides of the top surface of the bearing platform. Each winding mechanism includes two vertically opposite support seats. The inner side of each support seat is rotatably connected to a horizontally distributed first rotating shaft. The two first rotating shafts of each winding mechanism are coaxially and detachably fixedly connected to a winding shaft. The end of each first rotating shaft away from the winding shaft passes through the support seat and is provided with a positioning through hole. The positioning through hole is parallel to the radial direction of the first rotating shaft.

[0007] A vertical plate is also installed on the support platform located on one side of the bearing platform. The side of the vertical plate near the bearing platform is rotatably connected to a second rotating shaft that is coaxial with the first rotating shaft. A first drive motor installed on the vertical plate is drivenly connected to the second rotating shaft. A U-shaped frame with an inward U-shaped opening that can accommodate the end of the first rotating shaft is coaxially fitted on the end of the second rotating shaft near the bearing platform. A positioning screw that is coaxial with the positioning through hole is threaded onto the U-shaped frame. The positioning screw passes through the U-shaped frame.

[0008] Furthermore, each end of the first rotating shaft near the take-up shaft is coaxially fixedly connected to an arc-shaped block. The arc-shaped opening of the arc-shaped block is set upward, and both ends of the arc-shaped block are fixedly connected to vertically distributed locking screws. A locking plate is slidably connected between the two locking screws, and a locking sleeve is threaded onto the locking screw located above the locking plate. The end of the take-up shaft near the first rotating shaft is located inside the arc-shaped block.

[0009] Furthermore, each side of the arc-shaped block away from the first rotating shaft is fixedly connected to a limiting plate arranged coaxially with the first rotating shaft. The limiting plate has a U-shaped notch with an outward U-shaped opening along its radial direction. The arc-shaped surface of the U-shaped notch is adapted to the inner wall of the arc-shaped block. The end of the winding shaft near the first rotating shaft passes through the limiting plate through the U-shaped notch and is located inside the arc-shaped block.

[0010] Furthermore, the support platform is a shell structure with a cavity, and the bearing platform and the support platform are rotatably connected by an external toothed slewing bearing. The external toothed slewing bearing is coaxially arranged with the bearing platform, and a second drive motor installed in the support platform is drivenly connected to the external toothed slewing bearing.

[0011] Furthermore, reinforcing ribs are fixedly connected to both sides of the upright plate and the support platform.

[0012] Furthermore, a handwheel is fixedly fitted to the end of the positioning screw located outside the U-shaped frame.

[0013] The beneficial effects of this utility model by adopting the above technical solution are as follows:

[0014] Before use, a take-up shaft can be installed on each take-up mechanism. Then, by rotating the support platform, one of the first and second shafts of one take-up mechanism can be coaxially aligned. At this time, the end of the first shaft furthest from the take-up shaft can be located within the U-shaped frame, and the positioning screw can be coaxially aligned with the positioning through hole. Then, by rotating the positioning screw and inserting one end into the positioning through hole, the first and second shafts can be connected. During use, the take-up mechanism connected to the first drive motor is positioned near the gauze bandage's output position. When the first drive motor is started, it drives the take-up shaft to rotate and take up the gauze bandage. Until the gauze bandage on the take-up shaft is rolled to the required specifications, similar to existing technology, after the gauze bandage is cut and fixed, the positioning screw is rotated in the opposite direction. After the positioning screw is pulled out from the positioning through hole, the bearing platform is rotated so that one of the first rotating shafts and the second rotating shaft of the other take-up mechanism are coaxially aligned. Then, after the first rotating shaft and the second rotating shaft are connected by the positioning screw, the take-up of the gauze bandage can be restarted. During the take-up of the gauze bandage by this take-up mechanism, the take-up shaft on the previous take-up mechanism can be replaced at the same time, thereby reducing the downtime of the take-up device and improving the take-up efficiency.

[0020] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0021] like Figures 1 to 4 As shown, this utility model provides a winding device for producing gauze bandages, including a support platform 8, which is fixed in position during use. A horizontally distributed and rotatable bearing platform 1 is installed above the support platform 8. Two sets of symmetrically distributed winding mechanisms are installed on both sides of the top surface of the bearing platform 1. Each winding mechanism includes two vertically opposite support seats 7, and the four support seats 7 are located at the four corners of the bearing platform 1. The inner side of each support seat 7 is rotatably connected to a horizontally distributed first rotating shaft 5 through a bearing. The two first rotating shafts 5 of each winding mechanism are detachably and fixedly connected to a winding shaft 6 on the same axis, that is, the winding shaft 6 can be detached and replaced. Each first rotating shaft 5 has a positioning through hole 51 after passing through the support seat 7 at one end away from the winding shaft 6. The positioning through hole 51 is parallel to the radial direction of the first rotating shaft 5.

[0022] In addition, a vertical plate 9 is installed on the support platform 8 located on one side of the support platform 1. A second rotating shaft 4, which is coaxial with the first rotating shaft 5, is rotatably connected to the side of the vertical plate 9 near the support platform 1. A first drive motor 10, which is installed on the vertical plate 9, is driven and connected to the second rotating shaft 4. The first drive motor 10 is externally connected to a power supply and a start / stop switch. A U-shaped frame 2 with a U-shaped opening facing inward and capable of accommodating the end of the first rotating shaft 5 is coaxially fitted on the end of the second rotating shaft 4 near the support platform 1. Specifically, in the initial state, the U-shaped frame 2 is vertically distributed. A positioning screw 3, which is coaxial with the positioning through hole 51, is threaded onto the U-shaped frame 2. The positioning screw 3 passes through the U-shaped frame 2. Specifically, two positioning screws 3 coaxially arranged can be installed on both sides of the U-shaped frame 2. Either one of the two positioning screws 3 can be used or both can be used.

[0023] Specifically, before use, a take-up shaft 6 can be installed on each take-up mechanism. Then, by rotating the support platform 1, one of the first rotating shafts 5 and the second rotating shaft 4 of one take-up mechanism can be coaxially aligned. At this time, the end of the first rotating shaft 5 away from the take-up shaft 6 can be located inside the U-shaped frame 2, and the positioning screw 3 can be coaxially aligned with the positioning through hole 51. Then, by rotating the positioning screw 3 and inserting one end of the positioning screw 3 into the positioning through hole 51, the first rotating shaft 5 and the second rotating shaft 4 can be connected. During use, the take-up mechanism connected to the first drive motor 10 is located near the gauze bandage output position. When the first drive motor 10 is started, it can drive the take-up shaft 6 to rotate and take up the gauze bandage until the gauze bandage roll on the take-up shaft 6 forms the required specifications. This is consistent with existing technology. Similarly, after the gauze bandage is cut and fixed, the positioning screw 3 is rotated in the opposite direction and then pulled out of the positioning through hole 51. By rotating the support platform 1, one of the first rotating shafts 5 and the second rotating shaft 4 of the other winding mechanism can be set coaxially. At this time, the winding mechanism can be close to the output position of the gauze bandage. Then, after connecting the first rotating shaft 5 and the second rotating shaft 4 with the positioning screw 3, the winding of the gauze bandage can be restarted. During the winding process of the gauze bandage by the winding mechanism, the winding shaft 6 on the previous winding mechanism can be replaced at the same time, waiting for the next winding operation. When the gauze bandage roll on the winding mechanism is formed into the required specifications again, the above operation can be repeated, thereby reducing the downtime of the winding device and improving the winding efficiency.

[0024] Secondly, the first drive motor 10 of this utility model can be used to drive two sets of winding mechanisms to wind up, which can save costs compared with equipping each set of winding mechanisms with a drive device.

[0025] The specific arrangement of the detachable and fixed connection between the take-up shaft 6 and the first rotating shaft 5 on the same axis is as follows: Figures 1 to 4As shown, an arc-shaped block 11 is coaxially fixedly connected to one end of the first rotating shaft 5 near the take-up shaft 6. The arc-shaped opening of the arc-shaped block 11 faces upward, and vertically distributed locking screws 12 are fixedly connected to both ends of the arc-shaped block 11. A locking plate 13 is slidably connected between the two locking screws 12, and a locking sleeve 14 is threaded onto the locking screw 12 located above the locking plate 13. The end of the take-up shaft 6 near the first rotating shaft 5 is located inside the arc-shaped block 11. Specifically, in use, the take-up shaft 6 can be first... Both ends of the reel 6 are placed into the arc-shaped block 11. Then, the locking plate 13 can be slidably sleeved on the locking screw 12 and pressed against the reel 6. Finally, the locking sleeve 14 is sleeved on the locking screw 12. By rotating the locking sleeve 14 until the locking sleeve 14 is pressed against the locking plate 13, the reel 6 can be detachably and fixedly connected to the first rotating shaft 5 on the same axis. This makes it easy to install and remove the reel 6 between the two first rotating shafts 5 of each reel mechanism, thus making it easy to replace the reel 6.

[0026] Furthermore, such as Figures 1 to 4 As shown, each side of the arc-shaped block 11 away from the first rotating shaft 5 is fixedly connected to a limiting disk 15 coaxially arranged with the first rotating shaft 5. A U-shaped notch 16 with an outward U-shaped opening is formed on the limiting disk 15 along its radial direction. The arc-shaped surface of the U-shaped notch 16 matches the inner wall of the arc-shaped block 11. Specifically, the arc-shaped surface of the U-shaped notch 16 and the vertical cross-section of the inner wall of the arc-shaped block 11 are semi-circular structures with equal radii. The winding shaft 6 is located near the first rotating shaft 5. After passing through the limiting plate 15 via the U-shaped notch 16, the winding shaft 6 is located within the arc-shaped block 11. Specifically, during use, the winding shaft 6 can be placed on the limiting plate 15 through the U-shaped opening of the U-shaped notch 16. At this time, the winding shaft 6 is supported by the arc-shaped block 11 and the limiting plate 15. By setting the limiting plate 15 at both ends of the winding shaft 6, it is convenient to limit the two ends of the gauze bandage roll formed on the winding shaft 6, so as to limit the width of the gauze bandage roll.

[0027] The specific configuration of the rotating platform 1 is as follows: Figure 1As shown, the support platform 8 is a shell structure with a cavity. The support platform 1 and the support platform 8 are rotatably connected by an external gear slewing bearing 17. In the prior art, the inner ring of the external gear slewing bearing 17 is connected to the support platform 8, and the outer ring of the external gear slewing bearing 17 is connected to the support platform 1. The external gear slewing bearing 17 is coaxially arranged with the support platform 1, and a second drive motor 18 installed in the support platform 8 is drivenly connected to the external gear slewing bearing 17. The second drive motor 18 is a forward and reverse motor and is externally connected to a power supply and a start / stop switch. Specifically, the output shaft of the second drive motor 18 is vertically distributed, and after the output shaft of the second drive motor 18 passes through the support platform 8, a transmission gear 19 that can mesh with the external gear slewing bearing 17 is fitted on it. In use, when the second drive motor 18 is started, the support platform 1 can be driven to rotate under the cooperation of the transmission gear 19 and the external gear slewing bearing 17, so that the first rotating shaft 5 can be rotated to be coaxially arranged with the second rotating shaft 4.

[0028] Furthermore, such as Figure 1 As shown, reinforcing ribs 20 are fixedly connected to both sides of the upright plate 9 and the support platform 8. The reinforcing ribs 20 can improve the connection strength between the upright plate 9 and the support platform 8, thereby improving the structural stability of the winding device.

[0029] Furthermore, such as Figure 1 As shown, a handwheel 21 is fixedly fitted at the end of the positioning screw 3 located outside the U-shaped frame 2, and the handwheel 21 can facilitate the rotation of the positioning screw 3.
