DETAILED DESCRIPTION

[0018] The present invention provides a foam pad slotting device. To make the purpose, technical solution, and effects of the present invention more clear and explicit, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific examples described herein are only intended to explain the present invention and are not intended to limit the present invention.

[0019] See also Figure 1 、 Figure 2The utility model provides a foam mat slotting device, comprising a frame 1 and a conveyor belt 2, a traction mechanism 3 and a slotting mechanism 6 arranged on the frame 1, wherein the conveyor belt 2 is arranged at one end of the frame 1, for conveying the yoga mat to the traction mechanism 3 and the slotting mechanism 6; the traction mechanism 3 is provided with two groups, and the two groups of traction mechanisms 3 are respectively located in front of and behind the slotting mechanism 6, each group of traction mechanisms 3 includes rollers 4 arranged up and down and a second drive motor 5 for driving the rollers 4 to rotate. Under the action of the second drive motor 5, the two rollers 4 rotate relative to each other, and the yoga mat to be slotted passes between the two rollers 4 and is pulled forward under the action of the rollers 4; the slotting The mechanism 6 is arranged between the two groups of traction mechanisms 3, and includes a pressure roller 7, a grinding wheel roller 8 arranged below the pressure roller 7, and a first drive motor 9 for driving the grinding wheel roller 8 to rotate. The pressure roller 7 and the grinding wheel roller 8 are parallel to the roller 4 of the traction mechanism 3, and the lower surface of the pressure roller 7 is flush with the lower surface of the roller 4 located above the traction mechanism 3. The grinding wheel roller 8 includes a grinding wheel roller shaft 10 and a plurality of grinding wheels 11 sleeved on the grinding wheel roller shaft 10. The specific number of grinding wheels 11 can be set according to actual needs. The plurality of grinding wheels 11 are in contact with the lower surface of the yoga mat to be grooved, and by rotating the grinding wheel 11, the yoga mat moving forward is grooved, and the opened groove extends along the moving direction of the yoga mat.

[0020] During the specific implementation process, the yoga mat to be grooved is transported to the traction mechanism 3 located in front of the groove mechanism 6 via the conveyor belt 2, and enters between the pressure roller 7 and the grinding wheel roller 8 under the traction action of the traction mechanism 3. Under the action of the grinding wheel roller 8, the yoga mat is polished and grooved from the bottom of the yoga mat. The grooved yoga mat is pulled forward by the traction mechanism 3 arranged behind the groove mechanism 6.

[0021] During the grooving process, the depth of the grooving can be adjusted by adjusting the distance between the grinding wheel roller 8 and the pressure roller 7; during the grooving process, the yoga mat is kept in a tensioned state by adjusting the rotation speed of the two traction mechanisms 3. Generally speaking, the rotation speed of the roller 4 of the traction mechanism 3 located in front of the grooving mechanism 6 can be made lower than the rotation speed of the roller 4 of the traction mechanism 3 located behind the grooving mechanism 6, so that the yoga mat is kept in a tensioned state.

[0022] In this embodiment, a grooving mechanism 6 is provided and a grinding wheel 11 is used to groove the movable yoga mat. No heating or pressurization is applied during the grooving process. After grooving, the mat body at the corresponding position of the groove will not be compressed, deformed or hardened, and the flexibility and elasticity of the yoga mat can be maintained. Therefore, even if it is repeatedly folded along the groove, it will not crack or break, and has a longer service life.

[0023] It should be noted that the device is not limited to grooving yoga mats, but can also be used for grooving sports mats, outdoor mats, anti-slip mats and other mats with foam structures.

[0024] In order to facilitate the positioning of the yoga mat, a positioning edge 12 is provided on one side of the end of the conveyor belt 2 and on one side between the two traction mechanisms 3. During the specific implementation process, one side of the yoga mat to be grooved is attached to the positioning edge 12, so that it moves along the positioning edge 12. Therefore, the groove position can be easily determined to prevent the yoga mat from deviating during the movement.

[0025] In order to facilitate the adjustment of the number of grinding wheels 11 according to needs, or the adjustment of the position of the grinding wheel 11 according to the groove pitch, a plurality of sleeves 13 are provided on the grinding wheel roller 10. Figure 2 As shown, multiple grinding wheels 11 are fixed on the shaft sleeve 13, and the grinding wheel roller 10 is provided with a limiting groove 14 extending along its length direction. Correspondingly, the shaft sleeve 13 is provided with a limiting strip 15 adapted to the limiting groove 14, and a nut 16 for locking is provided on the shaft sleeve 13. Therefore, when it is necessary to fix the grinding wheel 11 or adjust the position or distance of the grinding wheel 11, it is only necessary to put the shaft sleeve 13 on the grinding wheel roller 10, adjust the position, and then tighten the nut 16 to fix the grinding wheel 11 at a certain position of the grinding wheel roller 10, which is very convenient.

[0026] Since the edge shape of the grinding wheel 11 affects the shape of the slot, an arc-shaped slot is easier to fold. Therefore, in a preferred embodiment, the edge of the grinding wheel 11 is arc-shaped, which makes the slotting faster and the cross-section of the slot is arc-shaped, which is more conducive to folding and more beautiful.

[0027] In order to facilitate the fixation of the traction mechanism 3 and the slotting mechanism 6, as shown in FIG. Figure 1 As shown, a plurality of portal frames 18 for supporting the traction mechanism 3 and the slotting mechanism 6 are further provided on the frame 1 , and the rotating shafts of the roller 4 , the pressure roller 7 and the grinding wheel roller shaft 10 can all be rotatably mounted on the portal frames 18 .

[0028] Since the thickness of the yoga mat is not fixed, whether in traction or grooving, it is necessary to adjust the distance between the rollers 4 and 4, or the distance between the pressure roller 7 and the grinding wheel 11 according to the thickness of the yoga mat. In this regard, as a further improvement, Figure 1As shown, the gantry 18 for mounting the rollers 4 located above the yoga mat, and the gantry 18 for mounting the rotating shaft of the pressure roller 7 are both provided with a slider 19. The slider 19 is used to rotate the rotating shaft connected to the rollers 4 or the pressure roller 7. The two ends of the slider 19 are slidably connected to the slide grooves provided on the two inner side walls of the gantry 18. The top of the slider 19 is threadedly connected to a screw rod 20. The top of the screw rod 20 passes through the top of the gantry 18 and is provided with a handwheel 21. During adjustment, by turning the handwheel 21, the slider 19 can drive the rollers 4 or the pressure roller 7 to move upward or downward, thereby adjusting the distance between the rollers 4 in the same group, or adjusting the distance between the pressure roller 7 and the grinding wheel 11, so as to adapt to yoga mats of different thicknesses.

[0029] Since chips are generated when the grinding wheel 11 is used to grind the slots, these chips will affect the workshop environment and cause pollution. Figure 1 As shown, a collecting trough 22 for collecting debris is further provided below the grooving mechanism 6. The collecting trough 22 has an inverted conical or inverted trapezoidal structure and is provided with an exhaust port at the bottom. The exhaust port is connected to the bag-type dust collector through a pipeline, and an exhaust fan is provided on the pipeline (the exhaust fan and the bag-type dust collector are existing technologies and are not shown in the figure). Through the action of the exhaust fan, a negative pressure can be formed in the collecting trough 22, and the debris collected in the collecting trough 22 is transported to the bag-type dust collector. The separation effect of the bag-type dust collector is utilized to separate and collect the debris to prevent air pollution.

[0030] To sum up, the foam mat grooving device described in the present invention, by providing a grooving mechanism 6 with a grinding wheel 11 and a traction mechanism 3 with a traction effect, can groove a yoga mat or other foam mat during movement. The formed grooves can be used as creases of the yoga mat, which is convenient for folding and storing the yoga mat. In addition, no heating or pressurizing is required during the grooving process. After grooving, the position of the mat body corresponding to the groove will not shrink and harden, and its original characteristics can be maintained. Therefore, it has better bending performance and a longer service life compared to indentations.
