Description

Technical Field

[0001] This utility model relates to the technical field of foam dressing processing equipment, and in particular to a foam dressing edge cooling and shaping mechanism. Background Technology

[0002] During the production process, foam dressings are cut and shaped using thermal cutting. Thermal cutting causes the cut edges of the dressing to melt instantly, and the molten edges only solidify and set during the subsequent cooling process.

[0003] In existing production processes, the edges in the molten state cool slowly and unevenly during natural cooling, which can cause shrinkage, deformation, or warping, affecting the final dimensional accuracy and flatness of the foam dressing. To improve the shaping effect, the cut dressing needs to be cooled. However, the existing processing methods are inadequate. In the current production process, the cutting, transfer, and cooling shaping processes are separated, and the degree of automation is low. Manual handling of material transfer and positioning is required, which not only leads to low production efficiency but also introduces the risk of secondary contamination through manual operation and makes it difficult to ensure that each piece of dressing is treated consistently.

[0004] In addition, the air cooling or contact static cooling methods used in the cooling process have the problem of uneven cooling. Different parts of the dressing edge have different heat dissipation rates, which still cannot completely avoid local deformation and cannot guarantee the precise shaping of the edge contour, thus affecting the overall quality of the product.

[0005] Therefore, this utility model proposes a foam dressing edge cooling and shaping mechanism to address the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems existing in the foam dressing edge cooling and shaping mechanism, such as uneven cooling of the edge after hot cutting of foam dressing leading to product deformation, low degree of automation in the production process, and low overall efficiency, this utility model aims to provide a foam dressing edge cooling and shaping mechanism with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a foam dressing edge cooling and shaping mechanism, including: a workbench, a conveyor belt and a cooling mechanism.

[0008] The cooling mechanism is located on one side of the conveyor belt to cool and shape the edges of the foam dressing conveyed by the conveyor belt.

[0009] Furthermore, the cooling mechanism includes a U-shaped groove block fixed to the top of the workbench. A first servo motor is fixedly installed on the right side of the outer wall of the U-shaped groove block and rotatably connected to a second rotating wheel. The output end of the first servo motor is fixedly connected to the first rotating wheel. The first rotating wheel and the second rotating wheel are connected by a belt for transmission. A fixing block is fixedly connected to the bottom of the outer wall of the belt. A hollow roller is rotatably connected to the right side of the fixing block. A cooler is installed inside the hollow roller.

[0010] Preferably, the foam dressing edge cooling and shaping mechanism provided by this utility model further includes a feeding mechanism, which is set at the feeding end of the conveyor belt and is used to push the foam dressing onto the conveyor belt.

[0011] Preferably, the feeding mechanism includes a vertical plate fixedly installed on the left side of the front end of the top of the workbench, a grooved wheel rotatably connected to the right side of the outer wall of the vertical plate, a rotating rod fixedly connected to the outer wall of the grooved wheel, and multiple flexible levers fixedly installed at equal intervals around the outer wall of the rotating rod.

[0012] Preferably, the feeding mechanism also includes a second servo motor installed on the left side of the outer wall of the vertical plate. The output end of the second servo motor is fixedly connected to a pin wheel, which is used to achieve intermittent engagement movement with the grooved wheel.

The cutting device includes a slide, an electric push rod is fixedly installed on the top of the slide, and a heating wire is fixedly connected to the bottom end of the electric push rod.

[0014] Preferably, the cutting device further includes a slide block fixedly connected to the front side of the top of the worktable, the slide block being slidable along the outer wall of the slide block.

[0015] Preferably, the cutting device further includes a battery block mounted on the top left side of the slide, the battery block being electrically connected to the heating wire to provide power.

[0016] Preferably, the axis of rotation of the hollow roller is parallel to the conveying direction of the conveyor belt, so that the hollow roller can roll and contact the side edge of the foam dressing as it moves with the belt.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model solves the problems of slow cooling speed, uneven effect, edge deformation or dimensional instability of foam dressing edges in the prior art by setting a cooling mechanism that moves synchronously with the conveyor belt and using hollow rollers with built-in coolers to roll and contact the hot melt edge of the foam dressing. It achieves rapid, efficient and uniform cooling and shaping of the dressing edge, significantly improving the molding quality and consistency of the product.

[0019] 2. This utility model integrates the heating wire cutting device, the flexible plate feeding mechanism, and the synchronously moving edge cooling mechanism into a single, interconnected design, and connects them via a conveyor belt.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] Example:

[0029] Please refer to Figures 1 to 5 This utility model embodiment provides a foam dressing edge cooling and shaping mechanism. A workbench 1 serves as the mounting base. A conveyor belt 10 is installed on the top of the workbench 1. A slide block 8 is fixedly connected to the front top of the workbench 1. A slide block 4 is slidably connected to the outer wall of the slide block 8. An electric push rod 5 is fixedly installed on the top of the slide block 4. A heating wire 7 is fixedly connected to the bottom end of the electric push rod 5. A battery block 6 is installed on the left side of the top of the slide block 4. The battery block 6 is electrically connected to the heating wire 7 to provide power. A feeding mechanism 3 is fixedly installed on the left side of the front end of the top of the workbench 1. Mechanism 3 is located at the feed end of conveyor belt 10 and is used to push foam dressing onto conveyor belt 10. The feeding mechanism 3 includes a vertical plate 301. A second servo motor 306 is installed on the left side of the outer wall of the vertical plate 301. A pin wheel 305 is fixedly connected to the output end of the second servo motor 306. A grooved wheel 302 is rotatably connected to the right side of the outer wall of the vertical plate 301. A rotating rod 304 is fixedly connected to the outer wall of the grooved wheel 302. Multiple flexible pavers 303 are fixedly installed at equal intervals around the outer wall of the rotating rod 304. The pin wheel 305 is used to achieve intermittent cooperation movement with the grooved wheel 302.

[0030] A cooling mechanism 2 is also fixed on the top of the workbench 1. The cooling mechanism 2 is arranged on one side of the conveyor belt 10 and is used to cool and shape the edge of the foam dressing conveyed by the conveyor belt 10. The cooling mechanism 2 includes a U-shaped groove block 9. A first servo motor 201 is fixedly installed on the right side of the outer wall of the U-shaped groove block 9. The output end of the first servo motor 201 is fixedly connected to the first rotating wheel 203. A second rotating wheel 206 is rotatably connected to the rear end of the right side of the outer wall of the U-shaped groove block 9. The first rotating wheel 203 and the second rotating wheel 206 are connected by a belt 207. A fixing block 202 is fixedly connected to the bottom of the outer wall of the belt 207. A hollow roller 204 is rotatably connected to the right side of the fixing block 202. A cooler 205 is installed at the right end of the interior of the hollow roller 204. The rotation axis of the hollow roller 204 is parallel to the conveying direction of the conveyor belt 10.

[0031] Please refer to Figure 1 and Figure 4 The cutting device consists of a slide block 8, a slide 4, an electric push rod 5, a heating wire 7, and a battery block 6. The slide block 8 is fixedly connected to the top front side of the worktable 1, providing guidance and support for the movement of the slide 4. The outer wall of the slide 4 is slidably connected to the slide block 8, thereby enabling free movement in the length direction of the slide block 8. The electric push rod 5 is fixedly installed on the top of the slide 4, and the heating wire 7 is fixedly connected to the bottom end of the electric push rod 5. The heating wire 7 is used for thermal cutting of foam dressings. The battery block 6 is installed on the top left side of the slide 4. The battery block 6 is electrically connected to the heating wire 7 to supply power to the heating wire 7.

[0032] During the cutting process, the slide block 4 can be manually pushed as needed to adjust the cutting position of the heating wire 7 on the worktable 1. After positioning is completed, the electric push rod 5 is activated. The electric push rod 5 extends downward, driving the heating wire 7 to contact and cut the foam dressing raw material placed on the worktable 1. Under the heating effect of the battery block 6, the heating wire 7 can quickly melt the foam material, achieving efficient and neat edge cutting.

[0033] The cutting device is designed with the cutting position adjustable. The sliding cooperation between the slide block 8 and the slide 4 ensures the accuracy and controllability of the cutting path. The electric push rod 5 provides a stable downward thrust, ensuring the cutting depth and consistency. The battery block 6 serves as an independent power source, allowing the heating wire 7 to quickly reach the working temperature when needed and to be free from the constraints of the external power cord, improving the convenience and safety of operation. The overall design of the cutting device is simple and efficient, achieving precise cutting of foam dressings and laying the foundation for subsequent feeding and cooling processes.

[0034] In a preferred embodiment, the cutting device also includes a slide bar seat 8, which is fixedly connected to the top front side of the workbench 1. The slide block 4 can slide along the outer wall of the slide bar seat 8. Through the sliding cooperation between the slide bar seat 8 and the slide block 4, the user can flexibly adjust the lateral position of the cutting device according to the size of the foam dressing or the cutting requirements, thereby accurately positioning the cutting area and ensuring that the cutting line is aligned with the edge of the dressing. This greatly improves the versatility and ease of operation of the equipment, enabling foam dressings of different specifications to be processed accurately.

[0035] In a preferred embodiment, the cutting device also includes a battery block 6, which is mounted on the top left side of the slide block 4. The battery block 6 is electrically connected to the heating wire 7 to provide power. The battery block 6 allows the heating wire 7 to be powered independently without the need for external power cables, which enhances the mobility and safety of the cutting device. When the electric push rod 5 drives the heating wire 7 to cut, the battery block 6 can quickly provide the required current to ensure that the heating wire 7 quickly reaches the melting and cutting temperature, achieving instant cutting response and improving cutting efficiency.

[0036] As a preferred embodiment, the foam dressing edge cooling and shaping mechanism also includes a feeding mechanism 3. The feeding mechanism 3 is located at the feed end of the conveyor belt 10 and is used to push the foam dressing onto the conveyor belt 10. The feeding mechanism 3 is designed to realize the automated transfer of the foam dressing after cutting. By quickly pushing the cut dressing onto the conveyor belt 10, it effectively avoids the contamination or secondary damage that may be caused by manual contact, while ensuring the continuity and efficiency of the production process.

[0037] In a preferred embodiment, the feeding mechanism 3 includes a vertical plate 301, which is fixedly installed on the left side of the top front end of the workbench 1. A grooved wheel 302 is rotatably connected to the right side of the outer wall of the vertical plate 301. A rotating rod 304 is fixedly connected to the outer wall of the grooved wheel 302. Multiple flexible push plates 303 are fixedly installed at equal intervals around the outer wall of the rotating rod 304, providing a stable installation platform and an effective feeding execution mechanism. The vertical plate 301 provides solid support for the subsequent transmission components. The combination of the grooved wheel 302, the rotating rod 304 and the flexible push plates 303 can periodically contact and push the dressing through rotation, ensuring the accuracy and reliability of the feeding action.

[0038] In a preferred embodiment, the feeding mechanism 3 also includes a second servo motor 306, which is mounted on the left side of the outer wall of the vertical plate 301. The output end of the second servo motor 306 is fixedly connected to a pin wheel 305, which is used to achieve intermittent engagement with the grooved wheel 302. The introduction of the second servo motor 306 provides a precise power source for the feeding mechanism 3. The intermittent engagement between the pin wheel 305 and the grooved wheel 302 enables the flexible dial plate 303 to achieve periodic dialing rather than continuous rotation, ensuring that the dialing is performed only after the dressing is cut and in place, effectively preventing damage to the dressing caused by accidental contact or premature dialing, and improving the accuracy of feeding and adaptability to the production rhythm.

[0039] In a preferred embodiment, the rotation axis of the hollow roller 204 is parallel to the conveying direction of the conveyor belt 10, so that the hollow roller 204 can roll and contact the side edge of the foam dressing as it moves with the belt 207. This ensures that the hollow roller 204 can roll and cool the dressing stably and evenly along the side edge of the dressing, maximizing the cooling contact area and time. Through rolling contact, friction damage is avoided, and the edge of the dressing is slightly rolled during the cooling process, which helps to further shape the edge and smooth the surface.

[0040] Working principle:

[0041] First, place the foam dressing raw material on the top front side of the workbench 1. Manually push the slide 4 along the slide bar 8 to position the heating wire 7 at the appropriate cutting position. Start the electric push rod 5. The electric push rod 5 extends downward and drives the heating wire 7, which is powered by the battery block 6, to perform thermal cutting on the foam dressing. After cutting, start the second servo motor 306 of the feeding mechanism 3. The output end of the second servo motor 306 drives the pin wheel 305 to rotate. The pin wheel 305 and the grooved wheel 302 are intermittently engaged, driving the grooved wheel 302 to rotate intermittently. The grooved wheel 302 drives the rotating rod 304 and multiple flexible plates 303 fixed on the rotating rod 304 to rotate synchronously. The flexible plates 303 periodically push the cut foam dressing and push it down onto the conveyor belt 10 on the back side of the workbench 1.

[0042] When the foam dressing is carried forward by the conveyor belt 10, it enters the working area of ​​the cooling mechanism 2. At this time, the first servo motor 201 is started. The output end of the first servo motor 201 drives the first rotating wheel 203 to rotate. The first rotating wheel 203 drives the second rotating wheel 206 to rotate synchronously through the belt 207, thereby driving the belt 207 to perform cyclic transmission. The fixed block 202 fixed on the belt 207 and the hollow roller 204 rotatably connected to the fixed block 202 move synchronously with the belt 207. The moving speed of the hollow roller 204 matches the conveying speed of the conveyor belt 10, ensuring that the hollow roller 204 moves synchronously with the edge of the foam dressing. At the same time, the cooler 205 installed inside the hollow roller 204 starts to work, continuously cooling the hollow roller 204. As the conveyor belt 10 conveys, the hot melt edge of the foam dressing rolls into contact with the cold outer wall of the hollow roller 204, and the heat is quickly carried away, thereby achieving efficient, continuous and uniform edge cooling and shaping.
