Description

Technical Field

[0001] The invention relates to the technical field of foam coil production, and more specifically to an auxiliary feeding device for a yoga mat coil. Background Art

[0002] In the production of yoga mats, the bottom material that provides support and cushioning is combined with the surface material that provides anti-slip function. This composite structure provides better anti-slip effect and longer service life. This composite processing requires the use of auxiliary guiding devices to improve the composite production efficiency of yoga mats.

[0003] For example, a Chinese invention patent with a publication number (CN112093540A) discloses an auxiliary feeding device for a yoga mat coil, which comprises a bottom plate, a linear module is arranged on the bottom plate, a mounting seat is threadedly connected on the movable platform of the linear module, a guide roller, a supporting top plate and a transverse limit plate are arranged on the mounting seat from top to bottom in sequence, the guide roller is rotatably connected to the mounting seat, the supporting top plate is slidably connected to the mounting seat up and down, the transverse limit plate is slidably connected to the bottom plate left and right, and an adjusting screw is threadedly connected to the lower part of the mounting seat; the feeding of the yoga mat coil can be guided to prevent the yoga mat coil from dragging on the ground, and the feeding requirements of yoga mats with different distances from the yoga mat coil and different thicknesses and different widths can be met.

[0004] In the process of manufacturing yoga mats, the bottom layer coil and the surface layer coil need to be composited first until their length reaches the predetermined specification standard. Once the required composite length is reached, the cutting mechanism will be used to perform the cutting operation to separate the composited section from the overall coil to obtain a complete yoga mat product. However, after completing this step, in order to continue the next round of composite operations, the operator must manually pull the yoga mat coil to the corresponding position of the hot melt mechanism. This process is not only time-consuming, but also has certain safety risks, because the operator may be accidentally injured during the operation. This operation mode that relies on manual intervention obviously reduces the automation level of the entire composite production process and increases the complexity and labor intensity of production.

[0005] Therefore, there is an urgent need for a new yoga mat coil auxiliary feeding device to improve composite production efficiency, reduce manual operation links, and improve the level of automation. Summary of the invention

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides an auxiliary feeding device for a yoga mat coil to solve the problem in the above-mentioned background technology that after the composite length of the bottom coil and the surface coil reaches the specified specification, the formed section is separated from the coil by a cutting mechanism to obtain a finished yoga mat. However, before the next round of composite operation, the operator is required to pull the coil to the position of the hot melt mechanism, which is time-consuming and may cause accidental injury to the operator, and the composite production has insufficient automation.

[0041] Working principle of the present invention:

[0042] S1, coil pulling stage: when coils are required for composite production of yoga mats, the driven first reversible motor 708 drives the two screws 701 to rotate forward through the second transmission wheel 706 and the fixed transmission belt 707, so that the sliding block 703 threadedly sleeved on the screw 701 carries the first electric push rod 704 and the electric clamp 705 to move from outside to inside along the slide rails of the front and rear side walls of the conveyor 4, so that the electric clamp 705 clamps and pulls the coil to stretch to the side of the heater 2, that is, the coil on the reel is gradually unwound until the electric clamp 705 carries the free end of the coil to the guide transmission area;

[0043] S2, coil delivery stage: when the active end of the coil carried by the electric clamp 705 reaches the guide transmission area, the electric clamp 705 opens its jaws, so that the electric clamp 705 no longer clamps the active end of the coil, causing the roll to stop unwinding, and then the active end of the first electric push rod 704 drives the electric clamp 705 connected thereto to shrink, so that the electric clamp 705 leaves the top of the conveyor platform 4, and then the first reversible motor 708 drives the two screw rods 701 to rotate in the opposite direction through the second transmission wheel 706 and the fixed transmission belt 707, so that the sliding block 703 threadedly sleeved on the screw rod 701 carries the first electric push rod 704 and the electric clamp 705 to move from the inside to the outside along the slide rails of the front and rear side walls of the conveyor platform 4, until the sliding block 703, the first electric push rod 704 and the electric clamp 705 reach the initial position, preparing for the next cycle of clamping and feeding;

[0044] S3, positioning and handover stage: when the sliding block 703, the first electric push rod 704 and the electric clamp 705 reach the initial position, and the movable end of the coil stops in the guide transmission area, the electric clamp 603 bites and locks the lower booster 501, so that the upper and lower boosters 501 are connected as a whole through the swing rod 601, the connecting plate 602 and the electric clamp 603, so that the upper and lower boosters 501 have consistent mobility, and then the second reversible motor 902 driven drives the left and right guide transmission components 5 to rotate from the inside to the outside with the respective lower boosters 501 as the axis through the mirror-engaged gear 901, so that the upper booster 501 moves along the arc-shaped slide groove of the side wall of the guide frame 3 to the guide transmission area on the surface of the conveying platform 4, until the upper booster 501 presses on the coil located in the guide transmission area;

[0045] S4, guide transmission stage: when the upper booster 501 presses on the coil located in the guide transmission area, the electric clamp 603 opens its jaws and loosens the lower booster 501, so that the upper and lower boosters 501 are independent and do not have consistent movement, and the second reversible motor 902 drives the two lower boosters 501 to continue to rotate through the mirror-engaged gears 901, while the two upper boosters 501 are synchronously driven through the active transmission belt 502, so that the upper booster 501 pressing on the coil is driven from the inside to the outside to help the coil on the conveying table 4 to extend to one side of the lower booster 501, and then after the lower booster 501 takes over the coils from the left and right sides, it is guided to the bottom of the heater 2, and under the hot melting action of the heater 2 and the continuous pushing assistance of the guide transmission components 5 on the left and right sides, the bottom coil and the surface coil are hot-melted and composited together, and finally discharged from the discharge port at the bottom of the machine tool 1;

[0046] S5, cutting stage: when the length of the unwinding material of the roll reaches a predetermined value, the movable end of the first electric push rod 704 drives the electric clamp 705 connected thereto to approach and clamp the roll again, and then the movable end of the second electric push rod 802 drives the cutter 803 connected thereto to move toward the cutting groove on the surface of the conveyor 4 to punch and cut, until the roll clamped by the electric clamp 705 forms a new movable end, and the detached part continues to be hot-melted and compounded to one side of the heater 2 under the guide drive of the guide drive assembly 5, until the yoga mat is completely compounded and formed, and under the cooperation of the locking assembly 6, the second reversible motor 902 drives the two lower boosting parts 501 to rotate outward through the mirror-engaged gear 901, until the guide drive assembly 5 returns to its initial position;

[0047] The equipment cyclically executes the cyclic control process of S1-S5 to carry out continuous batch composite production of yoga mats.
