Description

Technical Field

[0001] This utility model relates to the technical field of foam pad production equipment, and in particular to a foam pad post-processing device. Background Technology

[0002] Foamed mats, such as yoga mats or exercise mats, often require post-processing after foaming to achieve specific functions. For example, creases are usually created on the top and bottom surfaces for easy folding and storage, and suede is often applied to the surface to provide the comfort of textile fabrics. However, existing mats typically achieve these creases through heat pressing, which often reduces flexibility at the creases. Furthermore, the textile-like feel of existing mats is usually achieved by laminating suede onto the surface. Therefore, mats with both creases and suede lamination are prone to suede peeling at the creases during use, leading to a shortened lifespan, insufficient product quality for long-term use, and a diminished user experience.

[0003] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a post-processing device for foam pads, which aims to solve the defect that existing foam pads with the feel and creases of textile fabrics are prone to delamination and separation during use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A post-processing apparatus for foam pads, comprising:

[0007] Conveyor belts are used to transport pads to be processed.

[0008] The grooving mechanism is equipped with a grinding wheel roller for grooving the pad.

[0009] The scratching mechanism is equipped with a scratching roller with needle tips for forming scratches on the surface of the pad.

[0010] A sanding mechanism, which is equipped with sanding rollers, is used to sand the scratches.

[0011] The traction mechanism, which has multiple sets, is used to pull the mat to be treated forward and to tension the mat.

[0012] In the foam pad post-processing device, the grooving mechanism further includes a first pressure roller disposed above the grinding wheel roller and a first driving mechanism for driving the grinding wheel roller to rotate, wherein the grinding wheel roller is provided with multiple grinding wheels.

[0013] In the foam pad post-processing device, the scratching mechanism further includes a second pressure roller disposed above the scratching roller and a second drive mechanism for driving the scratching roller to rotate. The scratching roller is provided with multiple rows of tapered needles for forming scratches on the surface of the pad.

[0014] In the foam pad post-processing device, the sanding mechanism further includes a third pressure roller disposed above the sanding roller and a third drive mechanism for driving the sanding roller to rotate, and the surface of the sanding roller is provided with a frosted layer.

[0015] In the foam pad post-processing device, the first pressure roller, the second pressure roller, and the third pressure roller are rubber rollers.

[0016] In the aforementioned foam pad post-processing device, a limiting plate is provided at the output end of the conveyor belt.

[0017] In the foam pad post-processing device, a collection tank is provided below the grooving mechanism, the scratching mechanism and the sanding mechanism. A discharge pipe is provided at the bottom of the collection tank, and the discharge pipe is connected to an external exhaust fan and a bag dust collector.

[0018] In the foam pad post-processing device, a plurality of bushings are fitted on the roller shaft of the grinding wheel roller. The grinding wheel is fixed on the roller shaft of the grinding wheel roller through the bushings. Furthermore, the roller shaft is provided with a limiting groove extending along its axial direction, and the bushing is provided with a limiting block adapted to the limiting groove.

[0019] Beneficial effects:

[0020] This invention provides a post-processing device for foamed pads. A grooving mechanism creates grooves on the surface of the pad to form creases for folding. A scratching mechanism creates a textured surface similar to textiles. A brushing mechanism further refines the scratches, resulting in a smoother, suede-like texture that is more comfortable. Pads treated with this device do not harden at the creases, making them less prone to breakage during use. The suede-like texture created by scratching and brushing prevents layer separation, resulting in a longer lifespan. Attached Figure Description

Detailed Implementation

[0025] This utility model provides a post-processing device for foam pads. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0026] Please see Figure 1-3 This utility model provides a post-processing device for foamed pads, including a frame 1 and a conveyor belt 2, a grooving mechanism 3, a scratching mechanism 4, a sanding mechanism 5, and a traction mechanism 6 mounted on the frame 1. The conveyor belt 2, the grooving mechanism 3, the scratching mechanism 4, the sanding mechanism 5, and the traction mechanism 6 are specifically described as follows:

[0027] Conveyor belt 2, which is located at one end of frame 1, is used to transport the pad to be processed;

[0028] The grooving mechanism 3 includes a grinding wheel roller 7, a first pressure roller 8 disposed above the grinding wheel roller 7, and a first drive mechanism 9 for driving the grinding wheel roller 7 to rotate. The grinding wheel roller 7 includes a roller shaft 24 and multiple grinding wheels 10 disposed on the roller shaft 24. The pad to be processed passes between the first pressure roller 8 and the grinding wheel roller 7. The upper and lower surfaces of the pad are in contact with the first pressure roller 8 and the grinding wheels 10, respectively. When the grinding wheels 10 rotate, the bottom surface of the pad can be grooved.

[0029] The scratching mechanism 4 includes a scratching roller 11, a second pressure roller 12 disposed above the scratching roller 11, and a second drive mechanism 13 for driving the scratching roller 11 to rotate. The scratching roller 11 and the second pressure roller 12 are parallel to the first pressure roller 8 and the abrasive roller 7, and the pad to be processed passes between the second pressure roller 12 and the scratching roller 11. The upper and lower surfaces of the pad are in contact with the second pressure roller 12 and the scratching roller 11, respectively. The scratching roller 11 is provided with multiple rows of conical needles 14, and the conical needles 14 of adjacent rows are staggered. When the scratching roller 11 rotates under the action of the second drive mechanism 13, it can form scratches on the surface of the pad.

[0030] The abrasive mechanism 5 includes an abrasive roller 15, a third pressure roller 16 disposed above the abrasive roller 15, and a third drive mechanism 17 for driving the abrasive roller 15 to rotate. The abrasive roller 15 and the third pressure roller 16 are parallel to the first pressure roller 8 and the abrasive wheel 7. The pad to be processed passes between the third pressure roller 16 and the abrasive roller 15. The upper and lower surfaces of the pad are in contact with the third pressure roller 16 and the abrasive roller 15, respectively. The surface of the abrasive roller 15 is provided with a frosted layer, which is used to abrade the scratches so that the scratches are finer and form a surface with a suede-like feel.

[0031] The traction mechanism 6 is provided in multiple sets. The multiple sets of traction mechanisms 6 are respectively set after the conveyor belt 2, the grooving mechanism 3, the scratching mechanism 4 and the sanding mechanism 5. Each set of traction mechanisms 6 includes an upper roller 18 and a lower roller 19 arranged vertically, and a fourth drive mechanism for driving the upper roller 18 and the lower roller 19 to rotate. Under the action of the multiple sets of traction mechanisms 6, the pad to be processed moves forward, and the pad is tensioned by adjusting the speed of the traction mechanism 6.

[0032] In this embodiment, by setting up a grooving mechanism 3, a scratching mechanism 4, and a brushing mechanism 5, the mat to be processed can be grooved, scratched, and brushed sequentially to obtain a mat that has both creases and the texture of textile fabric. The grooving mechanism 3 creates creases for folding; the scratching mechanism 4 scratches to create a scratched texture similar to textile fabric; and the brushing mechanism 5 brushes to refine the texture of the scratched areas, giving it a suede-like feel for greater comfort. The mat processed by this device will not harden at the creases, making it less prone to breakage during use. Furthermore, the suede-like texture created by scratching and brushing prevents layer separation, resulting in a longer service life.

[0033] To ensure proper alignment of the pad during grooving, a limiting plate 21 is provided at the output end of the conveyor belt 2. This limiting plate 21 is located on one side and extends along the length of the frame 1 to the grooving mechanism 3. In practice, when the pad to be processed is conveyed from the conveyor belt 2 to the grooving mechanism 3, one side of the pad is brought close to the limiting plate 21 to facilitate alignment with the grinding wheel 10. The limiting plate 21 is also used as a reference when adjusting the spacing of the grinding wheel 10.

[0034] To accommodate the different spacing between creases on different pads, the spacing between the grinding wheels 10 needs to be adjustable. As one implementation, in addition to multiple grinding wheels 10 and roller shaft 24, the grinding wheel roller 7 is also provided with a bushing 25. The grinding wheels 10 are fixed on the bushing 25, and the bushing 25 is sleeved on the roller shaft 24 and can move along the axial direction of the roller shaft 24 and is locked by a nut. In addition, the roller shaft 24 is also provided with a limiting groove 26 extending along its axial direction, and the bushing 25 is provided with a limiting block 27 that matches the limiting groove 26. Therefore, it can be ensured that the bushing 25 will not slip when the grinding wheels 10 are rotating.

[0035] It should be noted that the first drive mechanism 9, the second drive mechanism 13, the third drive mechanism 17 and the fourth drive mechanism can be various types of motors, preferably motors with adjustable speed, so as to adjust the rotation speed of the grinding wheel 7, the brushing roller 11, the abrasive roller 15 and the upper roller 18 and the lower roller 19 according to actual needs.

[0036] In addition, to accommodate pads of different thicknesses, the heights of the first pressure roller 8, the second pressure roller 12, the third pressure roller 16, and the upper roller 18 are adjustable. For example, by setting a gantry frame 28, and setting an adjustable slider 29 on the gantry frame, the first pressure roller 8, the second pressure roller 12, the third pressure roller 16, and the upper roller 18 are rotatably fixed on the slider 29. By adjusting the height of the slider, the position heights of the first pressure roller 8, the second pressure roller 12, the third pressure roller 16, and the upper roller 18 can be adjusted.

[0037] When installing or adjusting the height, the top surfaces of the grinding wheel roller 7, the brush roller 11, and the polishing roller 15 are generally positioned at the same height. The ground surface of the lower roller 19 can be flush with (equivalent to the vertex of the cross-sectional circle) or higher than the top surfaces of the grinding wheel roller 7, the brush roller 11, and the polishing roller 15. Correspondingly, the bottom surface of the upper roller 18 (equivalent to the lowest point of the circle formed by the cross-section of the upper roller 18) can be flush with or higher than the bottom surfaces of the first pressure roller 8, the second pressure roller 12, and the third pressure roller 16. Preferably, the upper roller 18 is positioned higher than the first pressure roller 8, the second pressure roller 12, and the third pressure roller 16, while the lower roller 19 is positioned higher than the grinding wheel roller 7, the brush roller 11, and the abrasive roller 15, so that the pad body moves in a wavy pattern, and the grinding wheel roller 7 and the brush roller 11 can better process the lower surface of the pad body.

[0038] In a preferred embodiment, the first pressure roller 8, the second pressure roller 12, and the third pressure roller 16 are rubber rollers, so as to better cooperate with the grinding wheel roller 7, the brushing roller 11, and the polishing roller 15 to better perform grooving, brushing, and polishing.

[0039] Because debris is generated during grooving, scratching, and sanding, this debris can pollute the workshop environment and affect health. To address this, a collection trough 22 is provided below the grooving mechanism 3, scratching mechanism 4, and sanding mechanism 5. The collection trough 22 gradually narrows from top to bottom, and a discharge pipe 23 is provided at the bottom of the collection trough 22. The discharge pipe 23 is connected to an external exhaust fan and a bag filter dust collector. Therefore, under the action of the exhaust fan, a negative pressure can be formed in the collection trough 22, and the generated debris can be transported to the bag filter dust collector through the discharge pipe 23.

[0040] In summary, the foam pad processing device disclosed in this utility model, by setting the grooving mechanism 3, the scratching mechanism 4 and the abrasion mechanism 5, can form creases and textile textures on the surface of the pad, giving it a suede-like feel. Furthermore, since the textile texture is formed directly on the surface of the pad through scratching and abrasion, there will be no delamination, resulting in a longer service life.
