Description

Technical Field

[0001] This utility model relates to the field of yoga mat processing technology, and in particular to a multi-layer substrate pressing machine for composite yoga mats. Background Technology

[0002] With the increasing popularity of yoga, the market demand for composite yoga mats continues to grow. Composite yoga mats are typically made of multiple layers of substrates with different functions (such as anti-slip layers, cushioning layers, and breathable layers). The core of their processing lies in achieving tight bonding of the multiple substrates through pressing equipment, and it is necessary to ensure that the bonded product has uniform thickness, stable structure, and no air bubbles or delamination issues.

[0003] At present, the existing composite yoga mat pressing equipment has the following technical defects: (1) The spacing of the hot pressing rollers of most equipment is fixed or the adjustment structure is complicated, which cannot quickly adapt to the pressing requirements of substrates with different layers and different thicknesses, resulting in long debugging time and low production efficiency when changing product specifications; (2) Some equipment does not have a pressure limit for the feeding roller, and excessive extrusion can easily lead to damage to the substrate or deformation of the feeding roller, increasing equipment maintenance costs and product scrap rate.

[0004] In view of the shortcomings of the existing technology, there is an urgent need for a multi-layer substrate laminating machine for composite yoga mats to solve the pain points in current production and improve the processing quality and production efficiency of composite yoga mats. Utility Model Content

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

[0006] A composite yoga mat multi-layer substrate pressing machine is designed, comprising a main body. Within the main body, from right to left, are arranged a feeding roller group, a hot pressing roller group, and a discharging roller group. The hot pressing roller group includes two parallel first hot pressing rollers and a second hot pressing roller. Two adjacent adjusting grooves are symmetrically formed on the side walls of the main body, located between the feeding roller group and the discharging roller group. Vertically arranged first and second threaded rods are rotatably connected within the opposing adjusting grooves. The threads of the first and second threaded rods are opposite in direction. The tops of the first and second threaded rods rotatably extend out of the adjusting grooves, and the two first and two second threaded rods are connected by a transmission mechanism. A handle is connected to the top of one of the first threaded rods. A first slider and a second slider are threadedly fitted onto the first and second threaded rods, respectively. The first and second sliders are slidably connected to their corresponding adjusting grooves. The first hot pressing roller is rotatably positioned between two opposing first sliders, and the second hot pressing roller is rotatably positioned between two opposing second sliders. A reduction motor for driving the first hot pressing roller is mounted on one of the first sliders.

[0007] Furthermore, the feeding roller assembly includes an upper feeding roller and a lower feeding roller. Movable grooves are respectively opened on both side walls of the main body of the device at the location of the upper feeding roller assembly. Movable blocks are slidably arranged in the movable grooves. A movable rod penetrating the top of the main body of the device is connected to the top of the movable block. A compression spring is sleeved on the movable rod. The upper feeding roller is rotatably connected between the two opposing movable blocks.

[0008] Furthermore, a limiting block is provided at the top of the movable rod.

[0009] Furthermore, slide rails are provided on the inner walls of both sides of each adjusting slide groove, and connecting blocks are slidably connected in each slide rail. The two sides of the first slider and the second slider are respectively connected to the two connecting blocks.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. This utility model, by setting a first threaded rod and a second threaded rod with opposite thread directions and a synchronous transmission junction, allows the two hot press rollers to move synchronously in opposite directions by rotating a single handle. This can quickly adapt to the pressing requirements of substrates with different thicknesses and layers, significantly shortening the debugging time during production changeovers. Moreover, the sliding rail on the inner wall of the adjustable chute cooperates with the connecting block of the slider to provide precise guidance for the slider movement, ensuring that the two hot press rollers always remain parallel, effectively controlling the thickness deviation of the substrate after pressing, and improving the consistency of product dimensions.

[0012] 2. The structural design of the compression spring, movable rod, and moving block of the feeding roller assembly enables the upper feeding roller to have flexible pressing capability that adapts to the thickness of the substrate. This not only avoids slippage during substrate conveying but also prevents excessive compression that could damage the substrate. It significantly improves the alignment accuracy when feeding multi-layer substrates and reduces scrap due to misalignment during subsequent pressing.

[0013] 3. The limiting block at the top of the movable rod can limit the maximum downward sliding distance of the moving block, avoid excessive deformation of the compression spring causing excessive squeezing of the upper and lower feeding rollers, effectively protect the feeding rollers and substrate from damage, and reduce equipment maintenance costs.

[0018] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0019] Example 1

[0020] A composite yoga mat multi-layer substrate laminating machine, such as Figures 1 to 3 As shown, the device includes a main body 1. Within the main body 1, from right to left, are arranged a feeding roller group 16, a hot pressing roller group, and a discharging roller group. The hot pressing roller group includes two parallel first hot pressing rollers 14 and a second hot pressing roller 15. Two adjacent adjusting grooves 2 are symmetrically formed on both side walls of the main body 1, located between the feeding roller group 16 and the discharging roller group. A vertically arranged first threaded rod 3 and a second threaded rod 18 are rotatably connected within the opposing adjusting grooves 2. The threads of the first threaded rod 3 and the second threaded rod 18 have opposite directions, and their tops rotatably extend outwards... The adjusting slide 2 is connected to the two first threaded rods 3 and the two second threaded rods 18 by a drive mechanism, which can be achieved by a sprocket and chain. A handle 5 is connected to the top of one of the first threaded rods 3. A first slider 4 and a second slider 6 are threaded onto the first threaded rod 3 and the second threaded rod 18, respectively. The first slider 4 and the second slider 6 are slidably connected to the corresponding adjusting slide 2. The first hot press roller 14 is rotatably positioned between the two opposite first sliders 4. The second hot press roller 15 is rotatably positioned between the two opposite second sliders 6. A reduction motor that drives the first hot press roller 14 is provided on one of the first sliders 4.

[0021] Rotating handle 5 drives the first threaded rod 3 and the second threaded rod 18 to rotate synchronously. Since their threads are in opposite directions, this causes the first slider 4 and the second slider 6 to slide in opposite directions along the adjusting groove 2, thereby adjusting the distance between the first hot press roller 14 and the second hot press roller 15. A geared motor drives the first hot press roller 14 to rotate, cooperating with the second hot press roller 15 to hot press and laminate the multi-layer yoga mat substrate fed by the feeding roller group 16. Finally, the finished product is output through the discharge roller group. The adjustable hot press roller group adapts to the pressing requirements of multi-layer substrates of different thicknesses, ensuring uniform pressing pressure and improving the bonding strength and product consistency of the composite yoga mat.

[0022] Each adjusting slide groove 2 has a slide rail on its inner side, and a connecting block 17 is slidably connected in each slide rail. The first slider 4 and the second slider 6 are respectively connected to the two connecting blocks 17 on their sides.

[0023] The connecting blocks 17, which connect the slide rails on both sides of the adjusting groove 2 to the slider, form a sliding guide structure. When the slider moves, the connecting blocks 17 slide smoothly along the slide rails, providing bidirectional guidance and support for the slider. This reduces the frictional resistance between the slider and the adjusting groove 2, ensuring the movement accuracy and stability of the first hot press roller 14 and the second hot press roller 15 during adjustment, avoiding uneven pressing gaps caused by slider offset, and further improving the pressing quality.

[0024] The feeding roller assembly 16 includes an upper feeding roller 12 and a lower feeding roller 13. Movable grooves 10 are respectively opened on both sides of the main body 1 at the location of the upper feeding roller 12 assembly. Movable blocks 11 are slidably arranged in the movable grooves 10. A movable rod 6 that penetrates the top of the main body 1 is connected to the top of the movable block 11. A compression spring 9 is sleeved on the movable rod 6. The upper feeding roller 12 is rotatably connected between the two opposing movable blocks 11.

[0025] The upper feeding roller 12 is slidably connected to the moving chute 10 via the moving block 11. The compression spring 9 on the movable rod 6 always applies downward elastic pressure to the moving block 11, ensuring that the upper feeding roller 12 and the lower feeding roller 13 are in close contact. When conveying the substrate, the elastic force of the spring can adapt to changes in the substrate thickness, ensuring that the substrate is subjected to stable force during the feeding process. This achieves flexible pressing during the feeding process, preventing slippage, offset, or damage to the substrate during conveying, ensuring the alignment accuracy of multi-layer substrates before entering the hot press roller assembly, and improving the subsequent pressing effect.

[0026] The limiting block 7 at the top of the movable rod 6 forms a mechanical limit with the top of the device body 1, restricting the maximum downward sliding distance of the moving block 11 along the moving slide 10. This prevents excessive compression between the upper feeding roller 12 and the lower feeding roller 13 due to excessive spring pressure. The limiting block 7 is provided at the top of the movable rod 6 to prevent the movable rod 6 from moving excessively downward due to spring force or external force, protecting the feeding roller assembly 16 and the substrate from damage, while ensuring the safety and stability of the equipment operation.

[0027] The working process of this utility model is as follows: The operator rotates the handle 5 corresponding to the hot press roller group according to the number of substrate layers and total thickness of the composite yoga mat to be processed. The handle 5 drives one of the first threaded rods 3 to rotate. At this time, the two sets of threaded rods connected by transmission rotate synchronously. When the threaded rods rotate, the first slider 4 and the second slider 6 slide in opposite directions along the adjusting groove 2. That is, sliding in opposite directions reduces the hot press distance, and sliding in opposite directions increases the hot press distance. At the same time, the two sides of the slider move smoothly along the slide rail on the inner wall of the adjusting groove 2 through the connecting block 17 to ensure that the first hot press roller 14 and the second hot press roller 15 always remain parallel. After adjusting the hot press roller distance to match the substrate thickness, the operator stops rotating the handle 5 and the hot press parameters are preset.

[0028] The multi-layer yoga mat substrate to be laminated is neatly stacked and fed between the upper feed roller 12 and the lower feed roller 13 of the feed roller group 16. The upper feed roller 12 is slidably connected to the movable groove 10 on the side wall of the main body 1 of the device via the movable block 11. The movable rod 6 at the top of the movable block 11 is fitted with a compression spring 9. The elastic force of the compression spring 9 continuously presses the movable block 11 downward, so that the upper feed roller 12 adapts to the thickness of the substrate and always maintains a stable pressing force. The substrate is smoothly and alignedly conveyed to the subsequent hot press roller group under the frictional drive of the upper and lower feed rollers 13.

[0029] During hot pressing, the geared motor on the first slider 4 is started, and the geared motor drives the first hot pressing roller 14 to rotate. The first hot pressing roller 14 and the driven second hot pressing roller 15 form a rolling pressure. The multilayer substrate conveyed from the feeding roller group 16 enters between the two hot pressing rollers. Under the action of the high temperature of the hot pressing roller and the rolling pressure, the contact surface of the multilayer substrate melts and bonds together to form a tightly structured composite substrate.

[0030] During the hot pressing process, the slider slides along the slide rail through the connecting block 17, and the two hot pressing rollers always remain parallel, ensuring that the pressing pressure in each area of ​​the substrate is uniform and avoiding local bubbles or delamination.

[0031] The yoga mat substrate, after hot-pressing and lamination, enters the discharge roller group under the continuous conveying of the hot-pressing rollers. The discharge roller group further guides the substrate to be smoothly output from the equipment.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
