Description

Technical Field

[0001] This utility model belongs to the field of cotton placemat processing technology, and specifically relates to a cutting device for cotton placemats. Background Technology

[0002] The main uses of cotton placemats include protecting the dining table, decorating the table, and enhancing the dining experience. Cotton placemats effectively protect tablecloths from oil stains and dirt, especially cotton tablecloths, avoiding the hassle of difficult cleaning. In addition, cotton placemats also have heat insulation and anti-scalding properties, effectively controlling the heat of tableware and protecting the table from damage by hot items.

[0003] Currently, a Chinese patent application with publication number CN222154306U and publication date of December 13, 2024, discloses a shearing device for producing floor mats, which includes a mounting frame, horizontal guide rails, an operating box, a conveyor belt, a laser cutter, a slide rail, and a compaction mechanism. Horizontal guide rails are connected to the lower left and right sides of the mounting frame, and operating boxes are slidably connected to the horizontal guide rails. A conveyor belt is located on the upper part of the mounting frame, and slide rails are connected between the upper parts of the operating boxes. A laser cutter is slidably connected to the slide rails, and a compaction mechanism for pressing the floor mat is located on the upper part of the operating box.

[0004] The shearing device used in the production of this type of floor mat utilizes a laser cutter to slide along horizontal guide rails and slide rails to cut the floor mats. In existing technology, a laser cutter is also required to cut cotton placemats. When cutting multiple small pieces of cotton placemats from a large piece of fabric, in order to ensure the surface of the cotton placemats is clean and convenient for subsequent use, the operator needs to manually remove the cut cotton placemats one by one from the conveyor belt to avoid the cotton placemats falling to the ground and causing pollution. This makes the storage of cotton placemats more troublesome, time-consuming and labor-intensive. Utility Model Content

[0005] The purpose of this invention is to provide a cutting device for cotton placemats, which can facilitate the efficient storage of the cut cotton placemats.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cotton placemat cutting device, comprising a frame, an active roller rotatably connected to one end of the frame, a drive motor disposed on the side of the frame for driving the active roller to rotate, a driven roller rotatably connected to the other end of the frame, a conveyor belt disposed between the active roller and the driven roller for supporting the fabric, a support plate disposed within the frame and located inside the conveyor belt, a slide rail disposed on the frame and located above the conveyor belt, a vibrating knife cutter slidably connected to the slide rail for cutting multiple cotton placemats from the fabric, and a horizontal guide rail disposed on the side of the frame for driving the slide rail to slide. Connecting arms are provided at one end of the frame and at both ends of the active roller, and the two connecting arms... A roll-up shaft is rotatably connected to the slide rail for the fabric roll to pass through. A pressure bar is provided on the lower side of the slide rail to press the fabric against the conveyor belt. A drive cylinder is provided at both ends of the slide rail, with one end connected to the slide rail and the other end connected to the pressure bar. A support rod for side support of the cotton placemat is provided at the end of the frame away from the connecting arm and near the driven roller. Fixed arms are provided on both sides of the frame away from the connecting arm. Two drive rollers arranged vertically between the two fixed arms are provided to move the cotton placemat. A drive component is provided on the fixed arm to drive the two drive rollers to rotate. A drop plate extending downward at an incline is provided between the two fixed arms for the cotton placemat to slide down. A storage box for storing the cotton placemat is provided on the ground below the drop plate.

[0007] A further feature of this invention is that the driving component includes a driving shaft disposed at the end of the driving roller and rotatably connected to a fixed arm, two connecting gears respectively connected to the ends of the two driving shafts and meshing with each other, a fixed motor disposed on the side of the frame and located below the driving roller, and a drive gear disposed on the output shaft of the fixed motor and meshing with the connecting gears.

[0008] A further feature of this invention is that a gap is provided between the lower side of the support rod and the conveyor belt for the waste edge formed by cutting to pass through.

[0009] A further feature of this invention is that the upper end of the connecting arm is provided with a connecting seat with a U-shaped cross section for embedding into the end of the unwinding shaft.

[0010] A further feature of this invention is that a positioning boss is provided on the inner wall of the connecting seat, and a positioning ring groove for the positioning boss to be embedded is provided on the outer peripheral wall of the unwinding shaft end.

[0011] A further feature of this invention is that the connecting arm is also provided with a connecting rod at one end hinged to the upper end of the connecting arm, and a pressure roller for pressing on the surface of the fabric is rotatably connected between the two connecting rods.

[0012] In summary, this utility model has the following beneficial effects:

[0013] 1. The vibrating knife cutter on the slide rail is used to cut the fabric on the conveyor belt. When the fabric needs to be transported, the drive cylinder first drives the pressure bar to move down and press the fabric against the conveyor belt. Then the drive motor drives the conveyor belt to drive the transmission and the slide rail also moves along the horizontal guide rail. Under the simultaneous action of the pressure bar and the conveyor belt, the fabric on the unwinding shaft can be unwound, thus realizing continuous cutting of the fabric.

[0014] Meanwhile, after the fabric is cut, it will form the required cotton placemats and waste edges. Since the cotton placemats are relatively thick and have a large area, when the side of the cotton placemat is transferred to the driven roller, the side of the cotton placemat will be suspended in the air. As the cotton placemat continues to move, it can be supported on the support rod. Then the side of the cotton placemat can enter between the two drive rollers. At this time, the drive component drives the two drive rollers to rotate, and the drive rollers can carry the cotton placemat to slide down the drop plate and into the storage box. Therefore, the operator no longer needs to manually remove the cotton placemats. Finally, it is conducive to the efficient storage of the cut cotton placemats.

[0015] 2. A fixed motor drives the drive gear to rotate, which in turn drives the connecting gear on the drive shaft to rotate. The rotation of the two connecting gears then drives the rotation of the two drive rollers.

[0016] 3. Once the side of the cotton placemat is suspended in the air, it can be supported on the support rod. However, the waste edge, being relatively narrow and small in area, will not be suspended in the air. At this point, the waste edge can pass through the gap between the support rod and the conveyor belt, thereby separating the waste edge from the cotton placemat.

[0017] 4. The upper end of the connecting arm can be stably embedded in the end of the unwinding shaft using the connecting seat, which is conducive to the stable unwinding of the unwinding shaft;

[0018] 5. When the unwinding shaft is embedded in the connecting seat, the positioning ring groove on the periphery of the end of the unwinding shaft allows the positioning boss in the connecting seat to be embedded. At this time, the position of the unwinding shaft can be positioned by the positioning ring groove and the positioning boss, which is conducive to the stable entry of the fabric onto the conveyor belt.

[0019] 6. When the fabric is unwound from the unwinding shaft and fed onto the conveyor belt, the pressure rollers press down on the fabric with their own weight, which helps the fabric to be laid flat and stable on the conveyor belt, making it easier to cut the fabric later.

Figure 1The cutting equipment for this type of cotton placemat includes a frame 1, a drive roller 11, a drive motor 12, a driven roller 13, a conveyor belt 14, a support plate 15, a slide rail 2, a vibrating knife cutter 21, and a horizontal guide rail 3. The drive roller 11 is rotatably connected to one end of the frame 1 via bearings, while the drive motor 12 is bolted to the side of the frame 1 and drives the drive roller 11 to rotate via belt drive. The driven roller 13 is rotatably connected to the other end of the frame 1 via bearings. The conveyor belt 14 is positioned between the drive roller 11 and the driven roller 13 and supports the fabric, which is transported from the drive roller 11 side to the driven roller 13 side. The support plate 15 (see reference...) Figure 3 The slide rail 2 is bolted to the frame 1 and located inside the conveyor belt 14. The lower surface of the conveyor belt 14 is supported by the support plate 15. The slide rail 2 is slidably connected to the frame 1 and located above the conveyor belt 14. The vibrating knife cutter 21 is slidably connected to the slide rail 2 and is used to cut multiple cotton placemats from the fabric. The horizontal guide rail 3 is fixed to the side of the frame 1 and is used to drive the slide rail 2 to slide. The working principle of the vibrating knife cutter 21 is that the motor drives the knife to vibrate at high frequency, and the vibration is converted into a horizontal cutting force to cut the material. Since the structure of the vibrating knife cutter 21 moving with the slide rail 2 and the horizontal guide rail 3 is existing technology, it will not be described in detail here.

[0030] Reference Figure 1 , Figure 2 At one end of the frame 1 and at both ends of the drive roller 11, there are connecting arms 4 extending vertically upwards, which are fixed by bolts. A unwinding shaft 5 for the fabric roll to pass through is rotatably connected between the two connecting arms 4. The upper end of the connecting arm 4 is welded with a connecting seat 41 with a U-shaped cross section for the end of the unwinding shaft 5 to be inserted. A positioning boss 411 is integrally provided on the inner wall of the connecting seat 41. At the same time, a positioning ring groove 51 for the positioning boss 411 to be inserted is provided on the outer wall of the end of the unwinding shaft 5. A connecting rod 42 is also provided on the connecting arm 4, one end of which is hinged to the upper end of the connecting arm 4. A pressure roller 421 for pressing on the surface of the fabric is rotatably connected between the two connecting rods 42 through a bearing.

[0031] Reference Figure 1 , Figure 3 , Figure 4 , Figure 6The lower side of the slide rail 2 is also provided with a pressure rod 22 for pressing the fabric against the conveyor belt 14. Both ends of the slide rail 2 are provided with a drive cylinder 23, one end of which is fixedly connected to the slide rail 2 and the other end of which is fixedly connected to the pressure rod 22. The drive cylinder 23 can drive the pressure rod 22 to move down and press against the fabric. A support rod 6 is fixed by bolts at the end of the frame 1 away from the connecting arm 4 and near the driven roller 13. The support rod 6 can provide side support for the cotton placemat that is suspended. At the same time, a gap is provided between the lower side of the support rod 6 and the conveyor belt 14 for the waste edge formed by cutting to pass through.

[0032] Reference Figure 1 , Figure 3 , Figure 5 The frame 1 has fixed arms 7 bolted to both sides of the end away from the connecting arm 4. Two drive rollers 71, arranged vertically, are positioned between the two fixed arms 7 to move the cotton placemats. A drive unit 8 is mounted on each fixed arm 7 to rotate the two drive rollers 71. A downwardly extending, inclined drop plate 9 is positioned between the two fixed arms 7 for the cotton placemats to slide off. The side of the drop plate 9 is fixed to the side of the frame 1 by rods and bolts. A storage box 10 for collecting the cotton placemats is located on the ground below the drop plate 9. The drive unit 8 includes a drive shaft 81, a connecting gear 82, a fixed motor 83, and a drive gear 84. The drive shaft 81 is fixed to the end of the drive roller 71 and rotatably connected to the fixed arm 7 via a bearing. The connecting gear 82 is keyed to the end of the drive shaft 81, and the two connecting gears 82 on the two drive shafts 81 mesh with each other. The fixed motor 83 is fixed to the side of the frame 1 by bolts and is located below the drive roller 71. The drive gear 84 is keyed to the output shaft of the fixed motor 83 and meshes with the connecting gear 82.

[0033] Principle: The vibrating knife cutter 21 on the slide rail 2 cuts the fabric on the conveyor belt 14. When the fabric needs to be transported, the drive cylinder 23 first drives the pressure rod 22 to move down and press the fabric against the conveyor belt 14. Then the drive motor 12 drives the conveyor belt 14 to drive the transmission, and the slide rail 2 also moves along the horizontal guide rail 3. Under the simultaneous action of the pressure rod 22 and the conveyor belt 14, the fabric on the unwinding shaft 5 can be unwound, thereby realizing continuous cutting of the fabric.

[0034] Meanwhile, after the fabric is cut, it will form the required cotton placemats and waste edges. Since the cotton placemats are relatively thick and have a large area, when the side of the cotton placemat is conveyed to the driven roller 13, the side of the cotton placemat will be suspended in the air. As the cotton placemat continues to move, it can be supported on the support rod 6, and the waste edge passes through the gap between the support rod 6 and the conveyor belt 14. Then the side of the cotton placemat can enter between the two drive rollers 71. At this time, the two drive rollers 71 are driven to rotate by the fixed motor 83 and the connecting gear 82. The drive rollers 71 can then drive the cotton placemat to slide down the drop plate 9 and enter the storage box 10. Therefore, the operator no longer needs to manually remove the cotton placemats, which can facilitate the efficient storage of the cut cotton placemats.
