Description

Technical Field

[0001] This utility model belongs to the field of fireproof rolling shutter door embossing technology, and provides an embossing device for the production of fireproof rolling shutter doors. Background Technology

[0002] Embossing of fire-resistant roller shutter doors refers to the embossing treatment applied to the surface of fire-resistant roller shutter doors. This is usually done to increase the door's aesthetics, improve its compressive strength, and enhance its fire resistance. Embossing technology typically involves using special molds and pressure equipment to press various textures or patterns onto the surface of the door material (such as steel plates or aluminum alloys). Different embossing styles can give the door different appearance effects, such as simulating wood grain, grid patterns, and wave patterns.

[0003] During the embossing process of fireproof rolling shutter doors, when double-sided embossing is required, it is usually necessary to adjust the distance between the two embossing rollers. The adjustment method is usually vertical height adjustment, which requires the two embossing rollers and the drive motors connected to the embossing rollers to move simultaneously. Especially if the equipment is large or frequent adjustments are required, the operation will be cumbersome and time-consuming. Utility Model Content

[0004] To address at least one of the aforementioned technical shortcomings, this utility model provides an embossing device for the production of fireproof rolling shutters, comprising a support frame consisting of two symmetrical support plates. Two sets of parallel support beams are distributed at the lower inner side of the support frame. Two hollow upper and lower pressure rollers are provided at the upper inner side of the support frame. Two servo motors, respectively connected to the left ends of the upper and lower pressure rollers, are bolted to the upper left side of the support frame. Adjustment components for adjusting the embossing spacing are provided on the upper and lower pressure rollers. The adjustment components include four sets of top support plates connected by adjustment plates and pressure boosting pipes connected by rotary joints. Elastic embossing rolls are detachably connected to the outer surface of the adjustment components. Several positioning grooves are formed on the surface of the top support plates around the edges, and hook surfaces are provided around the positioning grooves.

[0005] Furthermore, the four sets of adjustment plates are slidably connected around the upper and lower pressure rollers, and the tops of the four sets of adjustment plates extend to the outer sides of the upper and lower pressure rollers and are welded to the middle of the bottom of the top support plate.

[0006] Furthermore, each of the four sets of adjusting plates is provided with a matching sealing gasket at the sliding connection between it and the upper and lower pressure rollers.

[0007] Furthermore, the left end of the booster pipe, away from the rotary joint, extends into the interior of the upper and lower pressure rollers, and the right end of the booster pipe, away from the rotary joint, is connected to a booster pump that is bolted to the upper right side of the bracket.

[0008] Furthermore, the four sets of adjustment plates are arranged in a T-shape, and the four sets of top support plates are all arranged in an arc shape, with the four sets of adjustment plates and top support plates on the same concentric circle.

[0009] Furthermore, the inner perimeter of the elastic embossed roll has a rough surface, and the number and area of ​​the rough surface correspond one-to-one with the hook surface.

[0010] Furthermore, a number of positioning blocks are fixedly mounted on the center line of the rough surface, and the number of positioning blocks are adapted to a number of positioning grooves.

[0011] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0012] The booster pump pressurizes the hollow upper and lower pressure rollers through the booster pipe, which in turn forces the T-shaped adjusting plates inside the upper and lower pressure rollers to slide outward. This further expands the arc-shaped top support plates fixed to the adjusting plates, ultimately causing the elastic embossing rolls on the upper and lower pressure rollers, which are mounted around the four sets of top support plates, to move closer together. This allows for adjustment of the embossing spacing, further optimizing operation, reducing human intervention, and improving the convenience of the production process.

[0013] When it is necessary to change the embossing pattern, the elastic embossing roll can be torn off from the upper and lower pressure rollers, and then a corresponding elastic embossing roll can be replaced. When assembling the elastic embossing roll, simply engage and match the several positioning blocks on the inner side of the elastic embossing roll with the several positioning slots on the surface of the top support plate. This will allow the four sets of rough surfaces on the inner side of the elastic embossing roll to fit into the four sets of hook surfaces on the surface of the top support plate. The rough surfaces and hook surfaces interlock with each other to form a firm connection, which further enhances the stability of the elastic embossing roll after installation and prevents slippage.

[0019] Please refer to Figures 1 to 4 ;

[0020] This embodiment provides an embossing device for the production of fireproof rolling shutters, see reference. Figure 1 The system includes a support 1, which consists of two symmetrical support plates. Two sets of parallel support beams 5 are distributed on the lower inner side of the support 1. Two hollow upper pressure rollers 2 and lower pressure rollers 3 are provided on the upper inner side of the support 1. Two servo motors 4 are bolted to the upper left side of the support 1 and connected to the left ends of the upper pressure rollers 2 and lower pressure rollers 3 respectively. Adjustment components for adjusting the embossing spacing are provided on the upper pressure rollers 2 and lower pressure rollers 3. The adjustment components include four sets of top support plates 8 connected by adjustment plates 7 and pressure boosting pipes 14 connected by rotary joints 13. Elastic embossing rolls 6 are detachably connected to the outer surface of the adjustment components. Several positioning grooves 9 are opened on the surface of the top support plates 8 around the edges. Hook surfaces 10 are provided around the positioning grooves 9.

[0021] In practice, the device is installed at the end of the conveyor, with the upper pressure roller 2 and the lower pressure roller 3 positioned at the end of the conveyor. After the conveyor outputs the fireproof rolling shutter door, the fireproof rolling shutter door can be allowed to enter between the upper pressure roller 2 and the lower pressure roller 3 for embossing.

[0022] During the embossing process of the fireproof rolling shutter door, a booster pump applies pressure to the upper pressure roller 2 and lower pressure roller 3 through the booster pipe 14, creating a certain pressure that pushes the adjusting plate 7 to slide outward. As the adjusting plate 7 slides outward, the arc-shaped top support plate 8 fixed on it is expanded. Under the expansion action of the top support plate 8, the elastic embossing rolls 6 around the four sets of top support plates 8 are pushed closer to each other, thereby adjusting the embossing spacing between the upper pressure roller 2 and lower pressure roller 3, making it easier to emboss fireproof rollers of different thicknesses. The roller shutter door is embossed. When the embossing pattern needs to be changed, the elastic embossing roll 6 can be torn off from the upper pressure roller 2 and the lower pressure roller 3. Then, the elastic embossing roll 6 with the corresponding pattern can be replaced. When assembling the elastic embossing roll 6, it is only necessary to engage and match several positioning blocks 11 on the inner side of the elastic embossing roll 6 with several positioning grooves 9 on the surface of the top support plate 8. This will allow the four sets of rough surfaces 12 on the inner side of the elastic embossing roll 6 to fit with the four sets of hook surfaces 10 on the surface of the top support plate 8. The installation and replacement method is simple.

[0023] Further reference Figure 2 and Figure 4 Four sets of adjusting plates 7 are slidably connected around the upper pressure roller 2 and the lower pressure roller 3. The top of the four sets of adjusting plates 7 extends through to the outside of the upper pressure roller 2 and the lower pressure roller 3 and is welded to the bottom middle of the top support plate 8. Each of the sliding connection points between the four sets of adjusting plates 7 and the upper pressure roller 2 and the lower pressure roller 3 is provided with a matching sealing gasket. The four sets of adjusting plates 7 are T-shaped, and the four sets of top support plates 8 are arc-shaped. The four sets of adjusting plates 7 and the top support plates 8 are on the same concentric circle.

[0024] In practical implementation, the sliding connection design allows the adjusting plate 7 to be finely adjusted up and down as needed during different working processes. The adjusting plate 7, welded to the top support plate 8, provides support and stability, ensuring that the adjusting plate 7 can drive the top support plate 8 during adjustment. The sealing gasket needs to be precisely designed based on the specific dimensions, shape, and working environment of the adjusting plate 7 and the pressure roller. A well-fitting sealing gasket can better cooperate with these components, ensuring a sealing effect and preventing sealing failure due to excessive or insufficient clearance. The design of the sealing gasket not only prevents leakage and contamination but also improves the sliding performance between the adjusting plate 7 and the pressure roller, reducing jamming or operational malfunctions caused by excessive friction. The four sets of adjustment plates 7 adopt a T-shaped design. The T-shaped structure usually has good support and stability. The horizontal part provides a large contact surface, which can evenly distribute the pressure applied to the adjustment plate 7, while the vertical part can better connect with other components to ensure the stability of the overall structure. The four sets of top support plates 8 are arranged in an arc shape. The arc shape can better adapt to the contact and pressure bearing with the elastic embossed roll 6. The arc shape can smoothly distribute the force. The four sets of adjustment plates 7 and top support plates 8 are on the same concentric circle. This arrangement helps to ensure symmetry and balance. By arranging them on concentric circles, it can be ensured that the force distribution of each set of adjustment plates 7 and top support plates 8 is more even.

[0025] Further reference Figure 4 The left end of the booster pipe 14, away from the rotary joint 13, extends into the interior of the upper pressure roller 2 and the lower pressure roller 3. The right end of the booster pipe 14, away from the rotary joint 13, is connected to a booster pump that is bolted to the upper right side of the bracket 1.

[0026] In practical implementation, the booster pipe 14, through its design that penetrates the interior of the upper pressure roller 2 and the lower pressure roller 3, can directly guide the booster fluid provided by the booster pump into the interior of the pressure roller, thereby achieving pressure increase inside the pressure roller. The rotary joint 13 is designed to cope with the rotational movement between the booster pipe 14 and the support 1. It ensures that the booster pipe 14 can maintain its sealing while allowing the booster pipe 14 and the equipment connected to it to rotate freely during operation.

[0027] Further reference Figure 2 and Figure 3 The elastic embossed roll 6 has a rough surface 12 around its inner perimeter. The number and area of ​​the rough surface 12 correspond one-to-one with the hook surface 10. Several positioning blocks 11 are fixed on the center line of the rough surface 12. The several positioning blocks 11 are adapted to several positioning grooves 9.

[0028] In practical implementation, the number and area of ​​the rough surface 12 and the hook surface 10 correspond one-to-one, indicating that each rough surface corresponds to one hook surface. This ensures that the two surfaces have sufficient contact area when in contact, providing effective gripping force and stability. The rough surface 12 and the hook surface 10, through the cooperation of their surface roughness and hook-shaped structure, can effectively lock or connect, preventing them from sliding or separating during operation. The positioning block 11 on the center line of the rough surface 12 is used to ensure that the parts can be correctly aligned with the predetermined position during assembly. The positioning block 11, through cooperation with the positioning groove 9, can ensure that each part maintains precise alignment, thereby preventing any displacement, misalignment, or loosening. Combined with the elastic properties of the elastic embossing roll 6 itself, it can adapt to different working environments and load requirements. Since replacing the elastic embossing roll 6 only requires aligning the positioning block and the groove, without much disassembly and adjustment, this design is particularly suitable for application scenarios that require frequent changes of different patterns. Each time, only the elastic embossing roll with the corresponding pattern needs to be replaced, which is both convenient and efficient.
