Description

Technical Field

[0001] This utility model relates to the technical field of workpiece clamping or positioning devices, and in particular to an embossing device for pearl cotton sheets. Background Technology

[0002] Polyethylene foam, also known as EPE pearl cotton, is a non-crosslinked closed-cell structure and a new type of environmentally friendly packaging material. It is composed of countless independent air bubbles generated by the physical foaming of low-density polyethylene resin. It overcomes the shortcomings of ordinary foam, such as fragility, deformation, and poor resilience. It has many advantages such as water and moisture resistance, shock resistance, sound insulation, heat insulation, good plasticity, high toughness, recyclability, environmental protection, and strong impact resistance. It also has good chemical resistance and is an ideal substitute for traditional packaging materials.

[0003] Traditional EPE foam board embossing devices typically employ fixed pressing mechanisms. When processing EPE foam boards of varying thicknesses, these mechanisms cannot be flexibly adjusted to accommodate different thicknesses. When processing thinner EPE foam boards, the fixed pressing mechanism may apply excessive pressure, leading to over-compression or even damage to the board, severely impacting product quality. Conversely, when processing thicker boards, insufficient pressure results in unsatisfactory embossing effects, with unclear and incomplete patterns, thus increasing the product defect rate. Therefore, we propose an EPE foam board embossing device. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a device for embossing pearl cotton sheets. This device can solve the problem that the pressing mechanism of traditional pearl cotton sheet embossing devices is mostly a fixed structure. When facing the processing requirements of pearl cotton sheets of different thicknesses, it is not possible to flexibly adjust the pressing mechanism according to the thickness of the sheet. When processing thinner pearl cotton sheets, the fixed pressing mechanism may apply excessive pressure, causing the sheet to be over-compressed or even damaged, which seriously affects the product quality. When processing thicker sheets, insufficient pressure results in an unsatisfactory embossing effect, with unclear and incomplete patterns, which easily increases the defect rate of the product.

[0026] Please see Figure 1-4 This utility model provides a technical solution: an embossing device for pearl cotton boards, comprising:

[0027] Conveyor table 1, conveyor mechanism 2 is installed inside conveyor table 1, embossing support frame 3 is fixedly connected to the top of conveyor mechanism 2, and control panel is fixedly installed on the top of embossing support frame 3;

[0028] The sheet material limiting structure is located on the embossing support frame 3;

[0029] The sheet material limiting structure includes a limiting lifting frame 4, two mounting plates 9, two second electric telescopic rods 11, and multiple limiting rollers 7. The two mounting plates 9 are fixedly connected to both sides of the embossing support frame 3. The two second electric telescopic rods 11 are fixedly installed on the top of the corresponding mounting plates 9. The telescopic ends of the two second electric telescopic rods 11 slide through the corresponding mounting plates 9 and are fixedly connected to the limiting lifting frame 4. The limiting lifting frame 4 is located outside the embossing support frame 3. The multiple limiting rollers 7 are rotatably connected inside the limiting lifting frame 4. The multiple limiting rollers 7 are symmetrically arranged at both ends of the limiting lifting frame 4.

[0030] Two first electric telescopic rods 10 are fixedly installed on the top of the embossing support frame 3. The telescopic ends of the two first electric telescopic rods 10 slide into the interior of the embossing support frame 3 and are fixedly connected to the mounting frame 14. A drive motor 16 is fixedly installed inside the mounting frame 14. A threaded rod 15 is fixedly connected to the output end of the drive motor 16. The threaded rod 15 is rotatably connected inside the mounting frame 14.

[0031] A movable plate 13 is threaded onto the outer surface of the threaded rod 15. The top of the movable plate 13 is slidably connected to the inner top wall of the mounting bracket 14. A fixed cylinder 17 is fixedly connected to the bottom of the movable plate 13. An embossing head 12 is fixedly installed inside the fixed cylinder 17 by bolts. Multiple positioning posts are fixedly connected to the bottom of the embossing head 12.

[0032] Four fixed plates 6 are fixedly connected to the top of the conveyor table 1. An electric push rod 5 is fixedly installed on one side of each of the four fixed plates 6. The telescopic ends of the four electric push rods 5 slide through the corresponding fixed plates 6 and are fixedly connected to anti-deviation frames 8. Multiple anti-deviation rollers 18 are rotatably connected inside the four anti-deviation frames 8.

[0033] Furthermore, when using this device, the conveying mechanism 2 is activated. The conveying mechanism 2 is composed of two conveying rollers, a conveyor belt, and a motor. It drives the pearl cotton sheet to move on the conveying table 1. Based on the thickness of the pearl cotton sheet, two second electric telescopic rods 11 are activated via the control panel. The second electric telescopic rods 11 extend, causing the limiting lifting frame 4 to descend. Multiple limiting rollers 7 rotate within the limiting lifting frame 4 to limit the upper surface of the sheet, preventing the sheet from jumping up and down during conveying and ensuring stable horizontal conveying of the sheet. It also adapts to the limiting requirements of sheets of different thicknesses.

[0034] During the conveying process, the pearl cotton sheet may deviate. At this time, the four electric push rods 5 start to work. By adjusting the extension length of the electric push rods 5 through the control panel, the four anti-deviation frames 8 move closer to the sheet. Multiple anti-deviation rollers 18, which are rotatably connected inside the anti-deviation frames 8, contact the side of the sheet. When the sheet deviates, the anti-deviation rollers 18 apply a lateral force to the sheet to correct the conveying direction of the sheet and ensure that the sheet is always in the correct conveying path, avoiding inaccurate embossing position due to deviation.

[0035] When the pearl cotton sheet is conveyed to the embossing position, according to the required embossing depth, the two first electric telescopic rods 10 are activated via the control panel. The first electric telescopic rods 10 push the mounting frame 14 down, bringing the embossing head 12 closer to the sheet. At the same time, the drive motor 16 starts, and its output end drives the threaded rod 15 to rotate. Since the moving plate 13 is threadedly connected to the threaded rod 15 and its top is slidably connected to the inner top wall of the mounting frame 14, when the threaded rod 15 rotates, the moving plate 13 moves horizontally along the threaded rod 15, thereby driving the fixed cylinder 17 and the embossing head 12 inside to make a slight adjustment to the horizontal position. The multiple positioning posts at the bottom of the embossing head 12 first contact the sheet. The embossing head 12, as an electrically heated embossing component, is connected to an external power source and starts working, heating the embossing head 12 to a suitable temperature. This temperature can be set and adjusted via the control panel. Different materials and thicknesses of pearl cotton sheets require different embossing temperatures. The heated embossing head 12 can more effectively heat-melt the surface of the pearl cotton sheet, thereby clearly embossing the pattern.

[0036] As the mounting bracket 14 continues to descend, multiple positioning posts at the bottom of the embossing head 12 first contact the board. The length of the positioning posts is precisely designed so that when the positioning posts pass through the board, the embossing head 12 completely passes through the board, avoiding the embossing head 12 pressing down completely. This design can prevent the embossed pattern from being carried out when the embossing head 12 is lifted. On the other hand, the appropriate spacing makes it easy to remove the embossed pattern blocks later. During the embossing process, the embossing head 12 relies on its own heat and the applied pressure to form a predetermined pattern shape on the surface of the pearl cotton board.

[0037] This device controls the height of the limiting lifting frame 4 through two second electric telescopic rods 11, which can flexibly adjust the limiting height for plates of different thicknesses, ensuring the stability of the plates during the conveying process, avoiding excessive compression and damage to thin plates, and ensuring that thick plates can obtain sufficient pressure to clearly and completely press out patterns, thereby improving product quality and reducing raw material waste and production costs.

[0038] Structural Description: Conveyor Platform 1: As the basic support structure of the equipment, it provides an installation platform for the conveying mechanism and other components.

During the conveying process of the sheet material, they contact the upper surface of the sheet material, restricting the vertical displacement of the sheet material and ensuring stable horizontal conveying of the sheet material;

[0045] Anti-deviation frame 8: Driven by electric push rod 5, it moves closer to or further away from the pearl cotton board. It has multiple anti-deviation rollers 18 internally connected to rotate and is used to laterally limit the board during the board conveying process, prevent the board from deviating, and ensure that the board is conveyed to the embossing position along the correct path.

[0048] The second electric telescopic rod 11 is fixedly installed on the top of the mounting plate 9. Its telescopic end is fixedly connected to the limit lifting frame 4. By extending or shortening, it drives the limit lifting frame 4 to rise and fall, thereby realizing the adjustment of the limit height of pearl cotton boards of different thicknesses.

[0049] Embossing head 12: Installed inside the fixed cylinder 17 and fixed by bolts, it serves as an electrically heated embossing component. After heating, it presses patterns onto the surface of the pearl cotton board using its own heat and pressure. Multiple positioning posts fixed at the bottom prevent the embossing head from pressing down completely, ensuring the embossing effect and facilitating the removal of the patterned blocks.

[0050] Movable plate 13: threadedly sleeved on the outer surface of threaded rod 15, with its top slidably connected to the inner top wall of mounting bracket 14 and its bottom fixedly connected to fixed cylinder 17. When threaded rod 15 rotates, it moves horizontally along threaded rod, thereby driving embossing head 12 to make fine adjustments to its horizontal position so as to accurately align with the embossing position.

[0051] Mounting bracket 14: It is fixedly connected to the telescopic end of the first electric telescopic rod 10, and a drive motor 16 and a threaded rod 15 are installed inside it to provide installation space for these components. Under the action of the first electric telescopic rod, it drives the embossing head 12 to move up and down as a whole.

[0053] Drive motor 16: Fixedly installed inside mounting bracket 14, with its output end fixedly connected to threaded rod 15. It provides power for the rotation of threaded rod 15, thereby enabling fine-tuning of the horizontal position of embossing head 12 and ensuring accurate embossing positioning.
