Description

Technical Field

[0001] This utility model relates to the field of roller press technology, specifically a roller press for preparing wave-absorbing plates. Background Technology

[0002] Wave-absorbing panels are typically made of porous or composite materials and are used to absorb electromagnetic or sound waves and convert them into heat or other forms of energy. They are widely used in protection, stealth technology, electromagnetic interference control, noise reduction, acoustic environment improvement, and sound insulation.

[0003] For example, the roller press for preparing microwave absorbing panels disclosed in patent announcement number CN 222156761 U, although it overcomes the disadvantage of existing roller presses requiring many manual operation steps and resulting in low production efficiency, does not solve the problem that in existing roller presses for preparing microwave absorbing panels, the roller columns are generally fixed in a constant manner during use. This means that different equipment needs to be changed when different styles of microwave absorbing panels are required, which increases equipment costs. Furthermore, the microwave absorbing panels cannot be stored immediately after preparation, which may affect the quality of the microwave absorbing panels in the later stages. Utility Model Content

[0004] The purpose of this invention is to provide a roller press for preparing microwave absorbing plates, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A roller press for preparing a microwave absorbing plate includes a roller pressing mechanism. The roller pressing mechanism includes a main frame, a main roller pressing column, a first auxiliary roller pressing column, and a second auxiliary roller pressing column. The main roller pressing column is rotatably connected to the main frame. The first auxiliary roller pressing column is rotatably connected to the main frame and disposed on one side of the main roller pressing column. The second auxiliary roller pressing column is rotatably connected to the main frame and disposed on the other side of the main roller pressing column.

[0007] The main roller, the first auxiliary roller, and the second auxiliary roller are each independently equipped with a height adjustment mechanism at both ends. Through the design of multi-roller collaborative work and independent height adjustment mechanisms, this application can achieve efficient and uniform roller pressing of the wave-absorbing plate.

[0008] Preferably, the height adjustment mechanism includes an adjustment rod and a drive member for driving the adjustment rod to move along the height direction.

[0009] Furthermore, the height adjustment mechanism preferably includes a first adjustment rod, a second adjustment rod, and a third adjustment rod. The first adjustment rod is provided at both ends of the main roller, and the first adjustment rod is located at the top of the main frame. The second adjustment rod is provided at both ends of the first auxiliary roller, and the third adjustment rod is provided at both ends of the second auxiliary roller.

[0010] Furthermore, the driving component is preferably at least one of a motor driving component, a hydraulic driving component, a pneumatic driving component, and a lead screw and nut driving component.

[0011] Furthermore, preferably, a fixing ring is fixedly provided at the top of the adjusting rod, and a rotating shaft is provided inside the fixing ring. The advantage is that by setting the rotating shaft inside the fixing ring, the main roller can be fixed while the main roller is driven to rotate to perform the roller pressing work through the driving component.

[0012] Preferably, a first motor is provided on one side of the first adjusting rod, and the output end of the first motor is driven and connected to the main roller pressing column; a second motor is provided on one side of the second adjusting rod, and the output end of the second motor is driven and connected to the first auxiliary roller pressing column; a third motor is provided on one side of the third adjusting rod, and the output end of the third motor is driven and connected to the second auxiliary roller pressing column. The advantage is that by providing a motor on one side of each adjusting rod, the main roller pressing column, the first auxiliary roller pressing column, and the second auxiliary roller pressing column can be independently driven by different motors to rotate, thereby performing the rolling operation.

[0013] Preferably, fixed connecting rods are fixedly provided on both sides of the main roller pressing column. The advantage is that by inserting the fixed connecting rods into the rotating shaft, the stability during rotation can be ensured while the first motor drives it to rotate.

[0014] Preferably, at least one side of the main frame is provided with a receiving trough corresponding to the first auxiliary roller / second auxiliary roller, and the position of the receiving trough is lower than the position of the first auxiliary roller / second auxiliary roller. The advantage is that after the rolling process is completed, the microwave absorbing plate can be directly stored in the receiving trough, facilitating the collection and organization of the microwave absorbing plate and improving production efficiency.

[0015] Preferably, at least one side of the main frame is provided with a discharge slope, which is inclined from the higher first auxiliary roller / second auxiliary roller towards the lower receiving trough. The advantage is that the discharge slope can effectively reduce the risk of damage to the absorber panels during loading and unloading on the right-angled main frame, thus preventing the produced absorber panels from becoming defective. This design also facilitates the removal of the prepared absorber panels from the rollers and their collection along the discharge slope into the receiving trough, improving production efficiency.

[0016] Preferably, the outer surfaces of the main roller, the first auxiliary roller, and the second auxiliary roller are respectively fixedly provided with anti-slip pads. The advantage is that it prevents the absorption plate from failing to move during the roller pressing operation. The anti-slip pads can improve the continuity of the absorption plate feeding and prevent the problem of material breakage.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This roller press for preparing microwave absorbing panels uses a height adjustment mechanism to raise and lower the main roller, the first auxiliary roller, and the second auxiliary roller. During the operation, the angle between the main roller and the first and second auxiliary rollers can be changed in real time, thus producing microwave absorbing panels of different styles. Based on mechanical optimization, the roller press improves the precision and efficiency of microwave absorbing panel preparation and features a modular roller pressing assembly that can be quickly replaced.

[0019] The roller press of this invention has a compact mechanism and is easy to operate, which can reduce equipment investment and operating costs. At the same time, by improving production efficiency and reducing scrap rate, it can further reduce production costs.

[0020] To enhance the performance stability of the microwave absorbing plate, an independent height adjustment mechanism allows for precise control of the height of each roller, ensuring uniform thickness and consistent performance. Furthermore, the multi-roller collaborative design improves the uniformity of the rolling process, further enhancing the plate's performance stability. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-4 As shown, this utility model provides a technical solution:

[0028] A roller press for preparing a microwave absorbing plate includes a roller pressing mechanism 1. The roller pressing mechanism 1 includes a main frame 2, a main roller pressing column 4, a first auxiliary roller pressing column 5, and a second auxiliary roller pressing column 6. The main roller pressing column 4 is rotatably connected to the main frame 2. The first auxiliary roller pressing column 5 is rotatably connected to the main frame and disposed on one side of the main roller pressing column 4. The second auxiliary roller pressing column 6 is rotatably connected to the main frame and disposed on the other side of the main roller pressing column 4. Each of the main roller pressing column 4, the first auxiliary roller pressing column 5, and the second auxiliary roller pressing column 6 is independently provided with a height adjustment mechanism 7 at both ends.

[0029] The main frame 2 serves as the foundation support structure for the entire roller press. The main frame 2 possesses sufficient strength and stability to withstand the forces and vibrations generated during the roller pressing process. The main frame 2 may be equipped with mounting holes or slots for mounting the main roller press column 4, the first auxiliary roller press column 5, the second auxiliary roller press column 6, and the height adjustment mechanism 7.

[0030] The main roller 4 is the main working component of the roller press. Its surface may have a certain texture or pattern to increase the friction between it and the absorber plate and improve the roller pressing effect. The main roller 4 is mounted on the main frame 2 through rotating connecting parts such as bearings and can rotate under the drive of the drive device.

[0031] The first auxiliary roller pressing column 5 and the second auxiliary roller pressing column 6 are respectively arranged on both sides of the main roller pressing column 4, working together with the main roller pressing column 4 to perform multi-directional roller pressing on the wave-absorbing plate. The mechanism and installation method of the auxiliary roller pressing column are similar to those of the rotating shaft. They can also be installed on the main frame 2 through rotating connecting parts such as bearings, and rotate under the drive of the drive device.

[0032] The height adjustment mechanism 7 is used to drive the main roller 4, the first auxiliary roller 5, and the second auxiliary roller 6 to move up and down. This allows the roller press to change the angle between the main roller 4 and the first and second auxiliary rollers 5 and 6 in real time, so as to adapt to the production of different types of wave-absorbing panels. Through the collaborative work of multiple rollers and the design of the independent height adjustment mechanism 7, efficient and uniform rolling of the wave-absorbing panels can be achieved.

[0033] In a preferred embodiment, the height adjustment mechanism 7 includes an adjusting rod and a driving member for driving the adjusting rod to move along the height direction. The main roller 4, the first auxiliary roller 5, and the second auxiliary roller 6 are each independently provided with an adjusting rod at both ends, and the adjusting rod is driven by the driving member. The driving member can be at least one of a motor drive, a hydraulic drive, a pneumatic drive, and a lead screw and nut drive. Driven by the driving member, the adjusting rod can move the rollers up and down, thereby adjusting the height of the rollers and thus the included angle between the main roller and the auxiliary rollers.

[0034] In this embodiment, preferably, the height adjustment mechanism 7 includes a first adjustment rod 8, a second adjustment rod 9, and a third adjustment rod 10. The first adjustment rod 8 is provided at both ends of the main roller pressing column 4 and is located at the top of the main frame 2. The second adjustment rod 9 is provided at both ends of the first auxiliary roller pressing column 5 and the third adjustment rod 10 is provided at both ends of the second auxiliary roller pressing column 6. A fixing ring 11 is fixedly provided at the top of the first adjustment rod 8 and a rotating shaft 12 is provided inside the fixing ring 11. By setting the rotating shaft 12 inside the fixing ring 11, the main roller pressing column 4 can be fixed while the first motor 13 on one side drives the main roller pressing column 4 to rotate for roller pressing.

[0035] In this embodiment, preferably, a first motor 13 is provided on one side of the first adjusting rod 8, and the output end of the first motor 13 is driven and connected to the main roller pressing column 4; a second motor 14 is provided on one side of the second adjusting rod 9, and the output end of the second motor 14 is driven and connected to the first auxiliary roller pressing column 5; a third motor 15 is provided on one side of the third adjusting rod 10, and the output end of the third motor 15 is driven and connected to the second auxiliary roller pressing column 6. By providing a motor on one side of each adjusting rod, the main roller pressing column 4, the first auxiliary roller pressing column 5, and the second auxiliary roller pressing column 6 can be driven to rotate by different motors to perform the rolling operation.

[0036] In this embodiment, preferably, fixed connecting rods 16 are fixedly provided on both sides of the main roller pressing column 4. By inserting the fixed connecting rods 16 into the rotating shaft 12, its stability during rotation can be ensured while the first motor 13 drives it to rotate.

[0037] In this embodiment, preferably, a receiving trough 17 is fixedly provided on at least one side of the main frame 2. The position of the receiving trough is lower than the position of the first auxiliary roller pressing column 5 / the second auxiliary roller pressing column 6. That is, there can be one receiving trough 17. The receiving trough 17 can be provided on one side of the main frame 2 corresponding to the first auxiliary roller pressing column 5, and the position of the receiving trough 17 is lower than the position of the first auxiliary roller pressing column 5. The receiving trough 17 can also be provided on one side of the main frame 2 corresponding to the second auxiliary roller pressing column 6, and the position of the receiving trough 17 is lower than the position of the corresponding auxiliary roller pressing column. Of course, there can also be two receiving troughs 17, respectively corresponding to the first auxiliary roller pressing column 5 and the second auxiliary roller pressing column 6 on both sides of the main frame 2, and the position of each receiving trough 17 is lower than the position of the corresponding auxiliary roller pressing column. By providing receiving troughs, the absorbing panels can be directly collected in the receiving trough 1 after the rolling work is completed, which facilitates the collection and sorting of the absorbing panels and improves production efficiency.

[0038] In this embodiment, preferably, at least one side of the main frame 2 is provided with a discharge slope 3. The number of discharge slopes 3 corresponds to the number of receiving troughs 17; that is, when there are two receiving troughs 17, there are two discharge slopes 3; when there is one receiving trough 17, there is one discharge slope 3. The discharge slope 3 is inclined from the higher first auxiliary roller / second auxiliary roller towards the lower receiving trough 17. The discharge slope 3 effectively reduces the risk of damage to the absorber panels caused by the right-angled main frame 2 during loading and unloading, thus preventing the produced absorber panels from becoming defective. This design also facilitates the removal of the prepared absorber panels from the rollers and their collection along the discharge slope 3 into the receiving trough 17, improving production efficiency.

[0039] In this embodiment, preferably, anti-slip pads 18 are fixedly provided on the outer surfaces of the main roller 4, the first auxiliary roller 5, and the second auxiliary roller 6 to increase their roughness and prevent the absorption plate from failing to move during the roller pressing operation. The anti-slip pads 18 can improve the continuity of the absorption plate feeding and prevent the problem of material breakage.

[0040] In this embodiment, a roller press for preparing microwave absorbing panels is used by driving the main roller 4, the first auxiliary roller 5, and the second auxiliary roller 6 to move up and down via the first adjusting rod 8, the second adjusting rod 9, and the third adjusting rod 10, respectively. During the movement, the included angle between the main roller 4 and the first and second auxiliary roller 6 can be changed in real time, thus producing microwave absorbing panels of different styles. Based on the optimization of the mechanical mechanism, the roller press improves the preparation accuracy and efficiency of microwave absorbing panels and is designed with a modular roller pressing assembly that can be quickly replaced. The roller pressing columns can be connected to the main body of the roller press via a unique mechanical clamping mechanism. When different roller pressing columns are needed to produce different products, they can be customized according to the specific requirements of the absorbing plate, such as surface hardness, roughness, and diameter. This ensures that the raw material of the absorbing plate is accurately positioned when entering the roller pressing area, thereby improving the uniformity of the roller pressing and the quality of the finished product, and increasing production efficiency. The advantage is that in existing roller presses for producing absorbing plates, the roller pressing columns are generally fixed in a constant manner during use. This means that different equipment needs to be changed when different styles of absorbing plates are required, which increases equipment costs. After the wave-absorbing panels are prepared, they cannot be stored immediately, which may affect the quality of the wave-absorbing panels in the later stages. Therefore, a roller press for preparing wave-absorbing panels is proposed. The main roller press 4, the first auxiliary roller press 5, and the second auxiliary roller press 6 are driven to move up and down by the first adjusting rod 8, the second adjusting rod 9, and the third adjusting rod 10. During the movement, the included angle between the main roller press 4 and the first auxiliary roller press 5 and the second auxiliary roller press 6 can be changed, so that different styles of wave-absorbing panels can be produced. And through the receiving trough 17, the wave-absorbing panels can be directly collected and stored in the receiving trough 17 after the roller pressing work is completed.

[0041] During implementation, firstly, based on the thickness and material requirements of the absorbing plate, the heights of the main roller pressing column 4, the first auxiliary roller pressing column 5, and the second auxiliary roller pressing column 6 are adjusted using the height adjustment mechanism 7 to ensure they are in suitable working positions. Then, the absorbing plate material to be prepared is placed on the roller pressing columns, and the drive device is activated to rotate the roller pressing columns and roll the absorbing plate material. During the rolling process, the rotation speed and height of the roller pressing columns can be adjusted as needed to obtain the optimal rolling effect. After rolling is completed, the drive device is stopped, and the prepared absorbing plate is unloaded from the roller pressing columns and slid along the discharge slope 3 into the receiving trough 17, completing the entire preparation process.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
