[0028] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "middle", "upper", "lower", "left", "right", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0030] like Figure 1 and Figure 2 As shown, a sheet material loading device comprises a first support frame 1 and a second support frame 2 arranged in sequence, a material coil roller 3 is provided on the first support frame 1, a first loading roller 4 and a second loading roller 5 are provided at intervals in the middle and upper part of the second support frame 2, a pair of floating rollers 6 are provided in the middle and lower part of the second support frame 2, the pair of floating rollers 6 are connected to the second support frame 2 through floating components, and a guide roller 7 is also provided in front of the second support frame 2; the sheet material on the material coil roller 3 is pulled to the slitting and conveying platform 8 in front of the second support frame 2 via the first loading roller 4, the pair of floating rollers 6, the second loading roller 5 and the guide roller 7.

[0031] The sheet material feeding device can effectively unfold the sheet material in a rolled state and put it in a spread-out and appropriately relaxed state through the arrangement of the first feeding roller 4, the second feeding roller 5 and the floating roller 6, thereby releasing the stress existing in the rolling process, and can also smoothly pull the sheet material to the slitting and conveying platform to achieve continuous feeding of the sheet material.

[0032] The first support frame 1 is mainly used to support the raw material coil roll 3. The raw material coil roll 3 is large in size and weight. During the continuous feeding process, the diameter and weight gradually decrease, and the height position of the sheet material pulled out from the raw material coil roll 3 will also continue to change. The floating roller 6 can also float in this process to change the tension and traction between the rollers; the raw material coil roll 3 can be multiple and arranged side by side. After one roll is used up, it will be removed immediately, and another roll can quickly follow up to continue unloading, and at the same time, the next complete raw material coil roll can be added on the first support frame. This can greatly improve the feeding efficiency and reduce the replacement time of the coil roll.

[0033] The setting of the second supporting frame 2 can better install the first loading roller 4, the second loading roller 5 and the floating roller 6. The first loading roller 4 and the second loading roller 5 are located at the top and play a major traction and guiding role. The floating roller 6 can move up and down under the action of the floating component, so that the distance between it and the first loading roller 4 can be adjusted to change the overall tensioning degree and tensioning force, while also avoiding the floating of the sheet material to a great extent, thereby improving the stability of the sheet material feeding.

[0034] The guide roller 7 is arranged between the second support frame 2 and the slitting and conveying platform 8, and plays a guiding role before loading, so that the sheet material can be led out at a height position close to the slitting and conveying platform. Because the second loading roller and the floating roller are in the upper and lower positions, the guide roller 7 is in the middle to allow the sheet material to be led out at the middle position. The height of the guide roller can be flush with the slitting and conveying platform, or slightly lower than it. Compared with the loading roller and the floating roller, the structure of the guide roller can be set simpler, and can be a single guide roller shaft.

[0035] like Figure 4 As shown, this is a feeding arrangement of the present on-line device, the sheet material on the raw material coil roller 3 passes through the first feeding roller 4, passes under a pair of floating rollers 6 and then goes around to the second feeding roller 5, and is finally pulled from the guide roller 7 to the slitting and conveying platform 8 in front of the second support frame 2.

[0036] like Figure 5 As shown, another arrangement is provided, in which the sheet material on the raw material coil roller 3 passes through the first loading roller 4, passes under the left floating roller 6, goes around the second loading roller 5, then goes around under the right floating roller, and finally is pulled from the guide roller 7 to the slitting and conveying platform 8 in front of the second support frame 2.

[0037] Furthermore, a pair of limit disks are provided on the first loading roller 4, the second loading roller 5, the floating roller 6 and the guide roller 7, and the spacing between each pair of limit disks and the axial arrangement positions are basically the same, thereby limiting the axial position of the sheet material on the rollers and avoiding axial deviation of the sheet material during transportation.

[0038] Furthermore, the second support frame 2 is a rectangular frame, including a plurality of columns 201, and a long beam and a short beam 202 connected between the plurality of columns 201; the first loading roller 4 and the second loading roller 5 are respectively installed between a pair of columns 201, and the heights of the first loading roller 4 and the second loading roller 5 are higher than the raw material coil roller 3. The arrangement of the columns 201 facilitates the connection and installation of these loading rollers, and the arrangement of the short beam 202 can be used to connect the floating assembly.

[0039] In some embodiments, the floating assembly includes a pair of side connecting plates 9, a pair of the floating rollers 6 are installed between the pair of side connecting plates 9, a plurality of pulley groups are provided on the outer sides of the side connecting plates 9, and the short cross beams on both sides of the second support frame are respectively provided with a plurality of vertical guide shafts 11, and each group of the pulley groups is respectively rollingly clamped on one of the guide shafts 11.

[0040] By setting the pulley group, the side connecting plate 9 can move up and down along the guide shaft 11; in this embodiment, the floating roller 6 is adaptively floating, and the floating roller 6 uses its own gravity to press down the sheet material, and the side connecting plate 9 is slidably connected to one side of the guide shaft 11. When the force applied to the floating roller 6 changes, the floating roller 6 can rise or fall by itself, and the side connecting plate 9 passively moves along the guide shaft 11.

[0041] The guide shaft 11 not only plays a guiding role, but also limits the axial position of the floating roller 6 to prevent its axial shaking. The provision of multiple groups of guide shafts 11 can also prevent the side connecting plate from shaking relative to the guide shaft.

[0042] Further, such as Figure 3 As shown, the pulley block is composed of two groups arranged symmetrically; the pulley block comprises a pair of pulleys 10 arranged side by side, an arc groove is arranged on the circumference of the pulley 10, and the guide shaft 11 is passed through the pair of arc grooves.

[0043] The pair of pulleys 10 are close to each other, so that the pair of arc grooves appropriately clamp the guide shaft 11, that is, the pulley 10 can allow the guide shaft 11 to roll.

[0044] Furthermore, the guide shaft 11 is a guide rod or a guide steel rope installed in the second supporting frame. A limiter 12 is also provided above the guide shaft 11 to prevent the connecting plate from rising too high to avoid hitting the upper components.

[0045] In other embodiments, Figure 6 As shown, telescopic push rods 16 are further provided on both sides of the second support frame 2, and the telescopic push rods 16 are connected to the side connecting plates 9. In this way, the height of the floating roller 6 can be manually controlled by using the telescopic push rods 16 to adjust the height of the side connecting plates 9, and the telescopic push rods 16 can be pneumatic push rods or electric push rods.

[0046] Furthermore, a third feeding roller 13 is further provided in the second supporting frame 2 below the second feeding roller 5. The third feeding roller 13 is provided at this position to further tighten the sheet material to prevent it from being loosened.

[0047] Furthermore, an auxiliary bracket is provided in front of the second support frame 2, and a connecting ear plate 14 is provided on the auxiliary bracket. The connecting ear plate 14 is connected to and installed on the guide roller 7. This connection method is relatively simple. The connecting ear plate 14 can also be set to be adjustable in lifting and lowering, that is, a lifting seat is added under the connecting ear plate, so that the height of the guide roller can be adjusted.

[0048] Furthermore, a plurality of pairs of mounting seats are provided above the first supporting frame 1, and the mounting seats are connected to mount the raw material coil roll 3. The mounting seats are detachably mounted on the long crossbeam of the first supporting frame 1.

[0049] Furthermore, a feeding belt is provided on one side of the slitting and conveying platform 8 close to the guide roller, and a limiting roller 15 is provided obliquely above the feeding belt to play a limiting role and prevent the sheet material from floating up.

[0050] The slitting and conveying platform 8 uses the feeding belt to convey the sheet material to the bottom of the cutter, and uses the cutter to cut the sheet material into pieces according to the designed size. The cut sheet material will be conveyed to the baking station for heating and softening for subsequent molding.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
