Description

Technical Field

[0001] This utility model relates to the field of coating processing equipment technology, and more specifically, to a conductive foam calendering coating machine. Background Technology

[0002] Conductive foam is a high-performance material that combines conductivity and elastic compression properties. It is widely used in electromagnetic shielding and grounding of electronic products. One of the key processes in the production of conductive foam is to calender and coat a uniform conductive coating onto the surface of the foam substrate. This process requires a conductive foam calendering and coating machine. This equipment achieves continuous calendering and coating processing of conductive foam through a series of operations such as unwinding, coating, calendering, cooling and curing, and rewinding.

[0003] In actual production, when dealing with conductive foam workpieces of different thicknesses, it is necessary to adjust the distance between the coating roller and the follower roller accordingly to ensure the coating effect. At the same time, it is also necessary to adjust the distance between the two cooling rollers to ensure sufficient contact and cooling curing. This process requires two independent adjustments, which is cumbersome and time-consuming, and greatly affects the calendering and coating processing efficiency of conductive foam.

[0004] In view of this, we propose a conductive foam calendering and coating machine. Utility Model Content

[0019] In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] Please see Figure 1-5 This utility model provides a technical solution: A conductive foam calendering and coating machine includes a frame 1, an unwinding roller 11 rotatably connected to one end of the frame 1 for releasing conductive foam, a take-up roller 12 rotatably connected to the other end of the frame 1 for receiving conductive foam, and a motor 7 fixedly connected to the frame 1 for driving the take-up roller 12 to rotate. A coating unit 2 for coating the conductive foam is provided on one side of the unwinding roller 11. A cooling unit 3 for cooling and curing the coated conductive foam is provided between the coating unit 2 and the take-up roller 12. An adjustment component 4 is provided between unit 2 and cooling unit 3 for simultaneously adjusting the gap between the rollers of coating unit 2 and cooling unit 3. In specific implementation, the roll of conductive foam is installed on unwinding roller 11. During processing, the conductive foam first undergoes surface treatment in coating unit 2, then is shaped and cured in cooling unit 3, and finally is wound and collected by take-up roller 12 under the drive of motor 7. When it is necessary to process foam of different thicknesses, the operator can simultaneously change the gap between the rollers of coating and cooling unit 3 by adjusting component 4, reducing a lot of adjustment time.

[0022] Specifically, the coating unit 2 includes a first mounting frame 21 fixedly connected to the frame 1 and a follower roller 22 rotatably connected to the first mounting frame 21. Above the follower roller 22, a second movable frame 23 slidably connected to the first mounting frame 21 is provided. A coating roller 24 is rotatably connected to the second movable frame 23. The coating roller 24 is used to cooperate with the follower roller 22 to coat the conductive foam. The coating roller 24 is used to transfer and calender the conductive coating onto the surface of the foam. The second movable frame 23 can be slidably set in the vertical direction relative to the first mounting frame 21, which can drive the coating roller 24 to move closer to or away from the follower roller 22 below, thereby precisely adjusting the size of the coating gap.

[0023] In addition, the cooling unit 3 includes a second mounting frame 31 fixedly connected to the frame 1 and a first cooling roller 32 rotatably connected to the second mounting frame 31. A third movable frame 33 is slidably connected to the second mounting frame 31 above the first cooling roller 32. A second cooling roller 34 is rotatably connected to the third movable frame 33. The first cooling roller 32 is used to cooperate with the second cooling roller 34 to simultaneously cool and cure both sides of the conductive foam. This arrangement allows the coated conductive foam to enter the clamping area formed by the first cooling roller 32 and the second cooling roller 34. The two cooling rollers simultaneously contact the upper and lower surfaces of the foam to cool and shape it. The sliding of the third movable frame 33 can drive the second cooling roller 34 to rise and fall, thereby cooperating with the first cooling roller 32 to clamp foam products of different thicknesses and ensure the cooling and curing effect.

[0024] Furthermore, one end of the first cooling roller 32 and the second cooling roller 34 is fixedly connected to an inlet pipe 35 for introducing cooling water into the roller, and the other end of the first cooling roller 32 and the second cooling roller 34 is fixedly connected to an outlet pipe 36 for discharging cooling water out of the roller. The second mounting frame 31 is provided with a channel 37 for the movement of the inlet pipe 35 and the outlet pipe 36. Cooling water continuously flows into the hollow first cooling roller 32 and the second cooling roller 34 through the inlet pipe 35, carrying away the heat of the roller body and the conductive foam, and then is discharged from the outlet pipe 36. The channel 37 on the second mounting frame 31 provides a moving space for the follow-up lifting and lowering of the inlet pipe 35 and the outlet pipe 36.

[0025] Secondly, the adjustment assembly 4 includes a first connecting rod 41 fixedly connected between the second movable frame 23 and the third movable frame 33, a second connecting rod 42 fixedly connected between the first mounting frame 21 and the second mounting frame 31, and a second electric push rod 43 fixedly connected to the second connecting rod 42. The second electric push rod 43 is vertically arranged and its extended end is fixedly connected to the top of the first connecting rod 41. Since the first connecting rod 41 is fixedly connected to both the second movable frame 23 of the coating unit 2 and the third movable frame 33 of the cooling unit 3, when the extended end of the second electric push rod 43 extends or retracts, it can drive both to rise or fall synchronously. This arrangement enables synchronous adjustment of the coating gap and the cooling gap.

[0026] In addition, a first slider 5 with a T-shaped cross section is fixedly connected to both the second movable frame 23 and the third movable frame 33. The first mounting frame 21 and the second mounting frame 31 are both provided with a groove 6 that matches the size of the slider 5. This arrangement can ensure the stability of the coating roller 24 and the second cooling roller 34 during their rise and fall through the groove 6 and the slider 5, and can also ensure the consistency of the height at both ends of the coating roller 24 and the second cooling roller 34, thus ensuring the accuracy of the calendering process.

[0027] Furthermore, an adjusting roller 15 for adjusting the tension of the conductive foam is provided between the coating unit 2 and the cooling unit 3. A vertically arranged first electric push rod 13 is fixedly connected to the bottom of the frame 1. A first movable frame 14 is fixedly connected to the extended end of the first electric push rod 13. The first movable frame 14 is slidably connected to the frame 1, and the two ends of the adjusting roller 15 are respectively rotatably connected to the two ends of the first movable frame 14. The tension of the conductive foam can be ensured by the setting of the adjusting roller 15. In specific implementation, when the adjusting roller 15 is lowered, the conductive foam is supported and the tension increases; when the adjusting roller 15 is raised, the conductive foam relaxes and the tension decreases.

[0028] Working principle: When using this device, the conductive foam roll is released by the unwinding roller 11 into the coating unit 2. The coating roller 24 and the follower roller 22 work together to evenly calender and coat the conductive coating onto the foam surface. The coated foam enters the cooling unit 3. The first cooling roller 32 and the second cooling roller 34 simultaneously contact the upper and lower surfaces of the foam. The foam is quickly cooled and shaped by the internal circulating cooling water. The final product is then wound up and collected by the take-up roller 12. When processing foam of different thicknesses, the second electric push rod 43 of the adjustment component 4 is activated. Through the first connecting rod 41, the second movable frame 23 of the coating unit 2 and the third movable frame 33 of the cooling unit 3 are simultaneously driven to rise or fall, thereby precisely adjusting the coating gap and cooling gap in one go.

[0029] 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.
