Description

Technical Field

[0001] This utility model belongs to the field of fitted sheet manufacturing technology, and in particular relates to a dividing device for manufacturing waterproof fitted sheets. Background Technology

[0002] A fitted sheet is simply a fabric cover that is placed directly over a mattress; its main purpose is to wrap the mattress. Currently, fitted sheets are manufactured by cutting a whole piece of fabric into strips of the appropriate width to facilitate further processing.

[0003] Patent application CN202322442630.1 discloses a cutting device for producing waterproof fitted sheets, belonging to the field of fitted sheet manufacturing technology. It includes a processing box with an inlet on one side and an outlet on the other. A fitted sheet roll is located on the side of the processing box near the inlet. Inside the processing box, from the inlet to the outlet, a dust-collecting component, a dust-cleaning component, an ironing component, and a cutting component are sequentially arranged. A cooling component is located on the exterior side of the processing box near the outlet. A scale is located at the rear end of the processing box. This invention, by including the dust-collecting component, facilitates the removal of loose threads from the top and bottom of the fitted sheet. The dust-cleaning component further cleans the top and bottom of the fitted sheet, improving cleaning efficiency and facilitating subsequent processing. The ironing component irons the fitted sheet flat before cutting, preventing uneven cutting and ensuring quality.

[0004] Existing technologies use dust-collecting components to absorb the lint produced by cutting, but there are still shortcomings: First, existing cutting devices lack the ability to fix the fabric at the cutting point when cutting the cloth, which causes the fabric to shrink towards the cutting point during the cutting process. This results in uneven cuts and affects the overall cutting quality. Secondly, the existing fabrics previously lacked components for stretching the fabric, resulting in uneven fabric being conveyed to the cutting area for cutting, affecting the cutting accuracy and also causing a decrease in cutting quality. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this invention provides a cutting device for manufacturing waterproof fitted sheets. Through the arrangement of components such as an elastic ring, a second protrusion, and a sliding rod, this invention can effectively cut and adjust fitted sheets according to different width requirements while simultaneously forming a compression fixation on both sides of the cut area.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dividing device for producing waterproof fitted sheets, comprising two symmetrically arranged support plates, a storage roller rotatably disposed between the two support plates, an extrusion discharge assembly rotatably disposed on one side of each support plate, a support roller rotatably disposed above the storage roller between the two support plates, a first sliding rod slidably disposed above the support roller, a plurality of sliding discs slidably disposed outside the first sliding rod, an annular blade fixedly disposed on the outside of each sliding disc, a sliding ring rotatably disposed on both sides of each annular blade on the outer circumference of the sliding disc, an elastic ring rotatably disposed outside each sliding ring, and a plurality of elastic support assemblies circumferentially connected between every two adjacent sliding rings and elastic rings.

[0007] Optionally, the elastic support assembly includes a second protrusion disposed on the outer wall of the elastic ring, a sliding rod fixedly disposed on the inner end face of each second protrusion, a first protrusion fixedly disposed on one side of each second protrusion on the side wall of the slip ring, each sliding rod being slidably connected to its adjacent first protrusion, a limit block disposed on one side of each first protrusion at one end of the sliding rod, and a spring disposed on the outside of each sliding rod between the first protrusion and the second protrusion.

[0008] Optionally, each of the second protrusions has an anti-slip protrusion on its outer end face.

[0009] Optionally, the extrusion discharge assembly includes a first extrusion roller rotatably disposed between two support plates, a second extrusion roller rotatably disposed on one side of the first extrusion roller between the two support plates, a plurality of annular protrusions being disposed on the outside of the second extrusion roller, and an elastic membrane being disposed on the outside of the plurality of annular protrusions.

[0010] Optionally, a second sliding frame is provided on both sides of the second extrusion roller on the side wall of the support plate, and a slider is slidably provided inside each second sliding frame, and each slider is rotatably connected to its adjacent second extrusion roller.

[0011] Optionally, a first guide roller is rotatably disposed on one side of the support plate between the two support plates, and two second guide rollers are rotatably disposed above the first guide roller between the two support plates, with a leveling assembly slidably disposed on one side of the two second guide rollers.

Detailed Implementation

[0017] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example 1:

[0018] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 8 As shown, a dividing device for producing waterproof fitted sheets includes two symmetrically arranged support plates 10. A storage roller 11 is rotatably arranged between the two support plates 10. An extrusion discharge assembly is rotatably arranged on one side of each support plate 10. A damping ring 28 is provided at the connection between the storage roller 11 and each support plate 10. The damping ring 28 forms a reverse resistance to the rotation of the storage roller 11, so that when the extrusion discharge assembly stretches and discharges the fabric, the storage roller 11 can form a tensile tension between the storage roller 11 and the extrusion discharge assembly under the action of the damping ring 28. A support roller 13 is rotatably arranged above the storage roller 11 between the two support plates 10. A first sliding rod 14 is slidably arranged above the support roller 13. First sliding frames 35 are provided on both sides of the first sliding rod 14 on the upper end surface of the support plate 10. Each first sliding frame 35 is slidably connected to one end of the first sliding rod 14. Each first sliding frame 35 has a first push cylinder 36 on its upper end face. The output end of each first push cylinder 36 passes through the first sliding frame 35 and is fixedly connected to the upper end face of the first sliding rod 14. Multiple sliding discs 15 are slidably arranged on the outside of the first sliding rod 14. Each sliding disc 15 has an annular blade 16 fixedly arranged on its outside. Each annular blade 16 has a sliding ring 42 rotatably arranged on both sides of the outer circular surface of the sliding disc 15. Each sliding ring 42 has an elastic ring 17 rotatably arranged on its outside. The elastic ring 17 is made of elastic deformable metal, thereby ensuring that the compression between the elastic ring 17 and the support roller 13 forms a fixation during fabric cutting. Multiple elastic support components are arranged in a ring shape between every two adjacent sliding rings 42 and elastic rings 17.

[0019] When cutting fitted sheet fabric, the distance between multiple sliding discs 15 is adjusted according to actual production needs. Then, two first push cylinders 36 are activated, and the output ends of the two first push cylinders 36 synchronously drive the first slide rod 14 to slide. The distance between the annular blade 16 and the support roller 13 is adjusted according to the thickness of the fabric to be cut. Then, under the pulling action of the extrusion assembly, multiple annular blades 16 and the support roller 13 squeeze and rotate to cut the fabric. During this process, the elastic rings 17 on both sides of the annular blade 16, under the action of the elastic support assembly, make the elastic rings 17 and the support roller 13 form an elastic compression on both sides of the fabric cutting, so that the fabric will not shrink towards the annular blade 16 during the cutting process, thus ensuring the overall cutting quality. Moreover, when not cutting, the two elastic rings 17 and multiple elastic support assemblies can shield the annular blade 16, so that the annular blade 16 is not directly exposed to the outside, thus protecting the operator.

[0020] It should be noted that each sliding disk 15 has a fixing structure on one side wall that is fixed to the first sliding rod 14. The position of the sliding disk 15 and other components is fixed by the compression between the bolt and the first sliding rod 14. When the horizontal position of the sliding disk 15 is adjusted, the sliding disk 15 and other components can be quickly adjusted by controlling the bolt.

[0021] Furthermore, such as Figure 5 As shown, the elastic support assembly includes a second protrusion 19 disposed on the outer wall of the elastic ring 17. A sliding rod 20 is fixedly disposed on the inner end face of each second protrusion 19. A first protrusion 18 is fixedly disposed on one side of each second protrusion 19 on the side wall of the slip ring 42. Each sliding rod 20 is slidably connected to its adjacent first protrusion 18. A limit block 22 is disposed on one side of each first protrusion 18 at one end of the sliding rod 20. The sliding arrangement between the sliding rod 20 and the first protrusion 18 guides the elastic deformation of the elastic ring 17. Furthermore, multiple sliding rods... With the rings 20 evenly distributed, they form concentric support for the slip ring 42 and the elastic ring 17, ensuring stable sliding between the elastic ring 17 and the support roller 13 during rotation, thus ensuring stable fabric cutting. Each sliding rod 20 has a spring 21 on its exterior between the first protrusion 18 and the second protrusion 19. Through the elastic tension of the spring 21 itself, it can further form elastic support between the slip ring 42 and the elastic ring 17, thereby ensuring the elastic compression of the fabric between the elastic ring 17 and the support roller 13, and thus ensuring the overall cutting quality of the fabric.

[0022] Furthermore, such as Figure 5As shown, each of the second protrusions 19 has an anti-slip protrusion 23 on its outer end face. The arrangement of multiple anti-slip protrusions 23 can drive multiple anti-slip protrusions 23 to rotate when the elastic ring 17 rotates. Then, when the elastic ring 17 and the support roller 13 form a compression on the fabric, the anti-slip protrusions 23 can further form a compression and fixation on the fabric with the support roller 13, further improving the cutting stability of the entire dividing device.

[0023] Furthermore, such as Figure 1 , Figure 4 and Figure 6 As shown, the extrusion discharge assembly includes a first extrusion roller 24 rotatably disposed between two support plates 10. A second extrusion roller 25 is rotatably disposed on one side of the first extrusion roller 24 between the two support plates 10. A second sliding frame 37 is disposed on both sides of the second extrusion roller 25 on the side wall of the support plate 10. A slider 38 is slidably disposed inside each second sliding frame 37. Each slider 38 is rotatably connected to its adjacent second extrusion roller 25. A servo motor for driving the second extrusion roller 25 to rotate is fixedly disposed on one side of one slider 38, which can drive the second extrusion roller 25 to rotate, thereby cooperating with the first extrusion roller 24 to discharge the fabric. A second push cylinder 39 is disposed on one side wall of each second sliding frame 37. The output end of each second push cylinder 39 passes through the second sliding frame 37 and is fixedly connected to one side wall of the slider 38.

[0024] During fabric winding, two second push cylinders 39 can be activated simultaneously. The output end of the second push cylinder 39 drives the slider 38 to slide inside the second sliding frame 37, thereby driving the second extrusion roller 25 to slide horizontally, increasing the distance between the first extrusion roller 24 and the second extrusion roller 25, allowing the fabric to pass through more easily. At the same time, the distance between the first extrusion roller 24 and the second extrusion roller 25 can be adjusted according to the actual thickness of the fabric to avoid damaging the internal layers of the fabric. The second extrusion roller 25 is provided with multiple annular protrusions 26 on its outside, and an elastic membrane 27 is provided on the outside of the multiple annular protrusions 26. The arrangement of the multiple annular protrusions 26 and the elastic membrane 27 allows the fabric to be discharged between the first extrusion roller 24 and the second extrusion roller 25. Each annular protrusion 26 forms a compression on the elastic membrane 27, causing multiple annular protrusions to form on the outer surface of the elastic membrane 27, thereby forming local compression on the fabric, increasing the overall discharge efficiency. Furthermore, the elasticity of the elastic membrane 27 itself can form protection for the layers between the fabric layers, improving the quality of fabric cutting. Example 2:

[0025] Based on Example 1, further examples are made, such as... Figure 1 and Figure 2As shown, a first guide roller 12 is rotatably disposed on one side of the support plate 10 between the two support plates 10. Above the first guide roller 12, two second guide rollers 29 are rotatably disposed between the two support plates 10. The two second guide rollers 29 are vertically disposed so that after the second guide rollers 29 support and guide the fabric, the fabric between the two second guide rollers 29 is in a vertical state. A stretching assembly is slidably disposed on one side of the two second guide rollers 29. The stretching assembly includes a second slide rod 30 slidably disposed on one side between the two second guide rollers 29. Multiple rotating disks 31 are rotatably disposed inside the second slide rod 30. The outer circumference of each rotating disk 31 is uniformly provided with multiple elastic levers in a ring shape. The plate 32 and the elastic lever 32 are made of flexible material. When in contact with the fabric, the elastic lever 32 will undergo elastic deformation, thereby preventing damage to the fabric. Each rotating disk 31 is equipped with an asynchronous motor on the upper end face of the second slide rod 30. The output end of each asynchronous motor passes through the second slide rod 30 and is fixedly connected to the upper end face of its adjacent rotating disk 31. The multiple rotating disks 31 are arranged symmetrically. The multiple rotating disks 31 on one side rotate clockwise under the drive of the asynchronous motor, and the multiple rotating disks 31 on the other side rotate counterclockwise under the drive of the asynchronous motor. However, they all drive the multiple elastic levers 32 and other components to push the fabric from the middle to both sides, thereby achieving the effect of stretching the fabric.

[0026] Both ends of the second slide rod 30 are provided with a third slide frame 40 on the side wall of the support plate 10. Both ends of the second slide rod 30 are slidably connected to the adjacent third slide frame 40. Each third slide frame 40 is provided with a third push cylinder 41 on one side wall. The output end of each third push cylinder 41 passes through the third slide frame 40 and is fixedly connected to one side wall of the second slide rod 30. The two third push cylinders 41 are started synchronously, which can move the two second slide rods 30 horizontally, thereby adjusting the contact distance of the fabric between the multiple elastic plates 32 and the two second guide rollers 29, so as to ensure the horizontal stretching effect of the multiple elastic plates 32 on the fabric.

[0027] Furthermore, such as Figure 7 As shown, each elastic lever 32 has an arc-shaped strip 33 at one end. The arc-shaped strip 33 increases the contact area between one end of the elastic lever 32 and the fabric, thereby increasing the stretching effect of the multiple elastic levers 32 on the fabric. Each arc-shaped strip 33 has multiple arc-shaped protrusions 34 on its outer arc surface. The multiple arc-shaped protrusions 34 make the arc surface of the arc-shaped strip 33 form a multi-point local stretching effect when it contacts the fabric, further increasing the stretching effect of the arc-shaped strip 33 on the fabric.

[0028] It should be noted that each pair of first push cylinder 36, second push cylinder 39 and third push cylinder 41 is controlled by a synchronous drive system, which is existing technology, to ensure the synchronous extension and retraction of their output ends, and thus ensure the synchronous movement of the parts connected to them.

[0029] Finally, it should be noted that the dividing device for producing waterproof fitted sheets of this utility model is intended to protect the various mechanical structures and related motion logic in this solution. Therefore, it does not elaborate on the various sensors, detectors, and driving components required for the actual operation of the specific mechanical structures. However, for those skilled in the art, various control systems and electrical connection methods, including various electrical components and driving components, can be completed using conventional technical means. As long as the beneficial effects or the specific actions during the above-mentioned work can be achieved, they can be implemented. This solution does not impose too many restrictions.

[0030] Furthermore, the servo motor, asynchronous motor, push cylinder, spring, etc. in the waterproof sheet production dividing device of this utility model are all purchased from the market. Technical personnel in this industry only need to install and operate it according to the accompanying instruction manual, without requiring any creative work from technical personnel in this field.
