Description

Technical Field

[0001] The utility model relates to the field of laminating plates, in particular to a flat thermal laminating machine. Background Art

[0002] For example, when using pearl cotton to make packaging products, the packaging products need to be formed by laminating multiple layers of pearl cotton. These packaging products often involve heat lamination, which is the process of hot pressing two separate pearl cotton sheets into a shape.

[0003] Traditional automated thermal bonding equipment uses a hot air blower to heat one side of two EPE foams, and then bonds the two together when the surface of the EPE foam melts.

[0004] However, during the thermal bonding process, the hot melting efficiency of the pearl cotton is slow. Research has found that the use of hot air cannot make the pearl cotton reach the melting point in time. It takes a heating time to melt one side of the pearl cotton. Therefore, traditional thermal bonding equipment has the problem of slow preparation efficiency. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a flat thermal laminating machine, aiming to solve the problem of slow preparation efficiency.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a flat heat laminating machine, characterized in that it includes a tool and a heating device located on both sides of the tool for heating the tool, and further includes spaced work tables, and a feeding mechanism located in the space between the work tables for guiding the plate material on the work tables, wherein the feeding mechanism has two rolling parts for guiding the output, the rolling parts are opposite to each other, and are used to clamp the plate material and pull the material to move in a single direction, and a non-contact gap is reserved between the rolling parts, and the tool is arranged in the gap, and the heating surface of the tool is opposite to the rolling parts respectively.

[0007] Furthermore, it also includes a mounting plate, an elastic tensioning device and a knife mounting plate for fixing the knife. The two ends of the knife pass through the mounting plate respectively and are connected to the knife mounting plate. The elastic tensioning device is arranged between the mounting plate and the knife mounting plate.

[0008] Furthermore, the elastic tensioning device includes a compression spring, one end of which is connected to the knife mounting plate, and the other end of which is connected to the mounting plate.

[0009] Furthermore, it also includes a driving mechanism for driving the rolling part to rotate, and the driving mechanism includes a driven gear, a driving motor, a rack, and a tensioning adjustment device. There are multiple driven gears, and the driven gears are coaxially connected to the rolling part and the motor shaft respectively. The tensioning adjustment device includes an adjusting gear, a transition slider, a guide rod, and a fixed block. The ends of the guide rod are respectively connected to the two fixed blocks. The transition slider and the guide rod are slidably connected. The adjusting gear is set on the transition slider, and the rack is engaged with the driven gear and the adjusting gear.

[0010] Furthermore, a height adjustment device is also included, which includes a threaded sleeve and a screw rod. The mounting plate is connected to the side of the threaded sleeve, and the screw rod is threadedly connected to the threaded sleeve.

[0011] Furthermore, a pressing roller is included, which is close to the two rolling parts and is partially or completely staggered with the tool.

[0012] Beneficial effects of the utility model:

[0013] The utility model uses a cutter and a heating device as a new heating device to heat one surface of two separate pearl cottons. From the efficiency point of view, the cutter directly acts on the plate material, and the efficiency of this heat transfer is much higher than the method of heating with hot air. At the same time, the feeding mechanism can also select the rolling part that clamps the material and moves, so as to achieve continuous bonding without stopping the feeding, and faster production capacity. In addition, another advantage of using a cutter and a heating device is that the structure is simpler and the heating efficiency is higher. It does not have the high energy consumption generated by preheating with a hot air blower, and does not have a complex internal layout. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] See also Figure 1-6 As shown, a flat heat laminating machine is used to heat-melt two sheet materials used for packaging boxes. There are many types of such materials. In order to make the explanation of the specification clearer and more understandable, this specific embodiment uses pearl cotton as the implementation object for a specific explanation. The selection of such an implementation object is not a further limitation of this solution.

[0021] The flat heat laminating machine includes a frame 1, and a workbench, a feeding mechanism, and a tool 2 arranged on the frame 1. In this embodiment, the workbench includes a group, namely a first workbench 100 and a second workbench 101. The first workbench 100 and the second workbench 101 are spaced apart, and this spacing forms a space for accommodating the feeding mechanism and the tool 2. The first workbench 100 and the second workbench 101 provide support surfaces. The pearl cotton is placed on the first workbench 100 and the second workbench 101. The pearl cotton is clamped and moved from the first workbench 100 to the second workbench 101 through two rolling parts (upper roller 31 and lower roller 32) in the feeding mechanism. A gap is reserved between the two rolling parts. The tool 2 is arranged in the gap. The upper surface and lower surface of the tool 2 correspond to the two rolling parts respectively. When the two independent pearl cottons contact the upper surface and lower surface of the tool 2 respectively, the heated sides of the two pearl cottons will have a sticky effect due to the instantaneous high temperature heating. After jumping over the tool 2, the two pearl cottons are bonded to each other.

[0022] The present invention uses a cutter 2 as a new heating device to heat one surface of two separate pearl cottons. From the perspective of efficiency, the cutter 2 directly acts on the plate material. The efficiency of this heat transfer is much higher than that of the hot air heating method. At the same time, the feeding mechanism can also select this rolling part that clamps the material to move, thereby achieving continuous bonding without stopping the feeding, and faster production capacity. In addition, another advantage of using this cutter 2 is that the structure is simpler and does not have a complicated layout inside the equipment after using a hot air blower.

[0023] The tool 2 is prior art, and its structure will not be described in detail.

[0024] Furthermore, it also includes a mounting plate 4, an elastic tensioning device, and a knife mounting plate 5 for fixing the knife 2. The mounting plate 4 is fixed on the frame 1, and the two ends of the knife 2 pass through the mounting plate 4 respectively and are connected to the knife mounting plate 5. The elastic tensioning device is arranged between the mounting plate 4 and the knife mounting plate 5; after the knife 2 heats up, the blade will stretch, and the elastic tensioning device provides an effect of adapting to the length change, that is, it can maintain the stability of the knife 2 on the frame 1, and ensure that the knife 2 will not arch.

[0025] Furthermore, the elastic tensioning device includes a compression spring 6, one end of which is connected to the knife mounting plate 5, and the other end is connected to the mounting plate 4; the deformation of the compression spring 6 can adapt to the elongation of the knife 2 due to heat, and the distance between the mounting plate 4 and the knife mounting plate 5 can be adjusted in time according to the length of the blade.

[0026] Furthermore, it also includes a driving mechanism for driving the rolling portion to rotate, and the driving mechanism includes a driven gear 71, a driving motor 72, a rack 73, and a tensioning adjustment device. There are multiple driven gears 71, and the driven gears 71 are coaxially connected to the rolling portion and the motor shaft of the driving motor 72 respectively. The tensioning adjustment device includes an adjusting gear 74, a transition slider 75, a guide rod 76, and a fixed block 77. The ends of the guide rod 76 are respectively connected to two fixed blocks 77, the transition slider 75 and the guide rod 76 are slidingly connected, the adjusting gear 74 is provided on the transition slider 75, and the rack 73 is engaged with the driven gear 71 and the adjusting gear 74; its purpose is to adjust the distance between the rolling portion and the tool 2, and the selection of pearl cotton also includes thickness.

[0027] Furthermore, a height adjustment device is also included, which includes a threaded sleeve 81 and a screw rod 82 . The mounting portion 83 is connected to the side of the threaded sleeve 81 , and the screw rod 82 is threadedly connected to the threaded sleeve 81 .

[0028] In the embodiment, a hand wheel 84 and a gear assembly are further included, and the hand wheel 84 drives the screw rod 82 to rotate through the gear assembly.

[0029] Furthermore, it also includes a pressing roller 9 arranged on the frame, which is close to the two rolling parts and is partially or completely staggered with the tool 2; when the two pearl cottons pass through the two rolling parts and are heated and attached to each other, the position of the pressing roller 9 has a blocking effect on the two pearl cottons, forcing the two pearl cottons to squeeze and deform each other, thereby improving the stability after heat bonding.

[0030] It should be noted that the positions of the two EPEs are pre-adjusted so that one side of the two EPEs is in contact with the two surfaces of the cutter 2 respectively.

[0031] The heating device is a prior art and can be a heating wire or other heating element, both of which realize heat transfer to the tool.

[0032] The above embodiments are merely descriptions of preferred embodiments of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering technicians in this field should fall within the scope of protection determined by the claims of the present invention.
