Description

Technical Field

[0001] The invention belongs to the technical field of thermally conductive soft rubber sheet production, and relates to a production line and a production method for continuous production of thermally conductive soft rubber sheets. Background Art

[0002] With the continuous development of thermal conductive soft film product technology, the requirements for thermal conductive soft film production technology, especially production equipment, are getting higher and higher. While requiring to improve production efficiency, the production equipment is often required to be simple and convenient to operate. In the existing production and processing of thermal conductive soft films, generally, equipment with different functions such as presses, laminators, calenders, heat curing machines and cutting machines are used to perform processing operations for different production processes. However, since these equipment with different functions are often independent, when producing soft films, each device needs to be operated separately, which makes the equipment operation extremely cumbersome, and the production processes between equipment are often repeated, which makes the production process complicated. All of the above reasons lead to low efficiency in the production and processing of soft films, which is not conducive to continuous production.

[0003] In order to improve the production efficiency of soft films, it is a common way to improve the production equipment through integration. For example, the Chinese utility model patent with patent number CN201320686733.6 discloses a thermal conductive film laminating machine. In addition to the original laminating function, the laminating machine also integrates cutting, winding and unwinding functions, which to a certain extent realizes the functional integration of a single laminating production equipment. However, this is only applicable to the improvement of production efficiency at a certain stage in production. For the production and processing of soft films at all stages, the functional integration of a single device is far from enough. The Chinese utility model patent with patent number CN202320406767.9 discloses a ceramic silicone calendering production line, which uses multiple devices to work together to improve production efficiency. However, in the thermal conductive soft film production industry, because its material is very soft, if the equipment is simply combined together, it is difficult to obtain products that meet quality requirements. In addition, in the calendering production process of soft films, the film often needs to be processed, and the degree of refinement is higher.

[0004] Therefore, there is an urgent need for a thermally conductive soft film production and processing technology that can improve the current situation of independent operation of existing soft film production equipment, and provide a production line that is simple and convenient to operate, suitable for continuous production, especially for soft films, so as to achieve the purpose of improving production efficiency.

The rollers can move relative to each other, and the traction force on the product line can be adjusted by adjusting the distance between the rollers.

[0035] More specifically, the surface of the traction roller set is made of plastic material, preferably rubber, and the large friction of the rubber surface facilitates the generation of sufficient pulling force to pull the product line forward;

[0036] Specifically, the cutting machine 5 further includes a conveying mechanism 51, which is located before the traction mechanism 52 and is arranged on the bottom surface of the horizontal product line to provide a horizontal driving force for the horizontal product line; the conveying speed of the conveying mechanism 51 is greater than the running speed of the horizontal product line;

[0038] During the operation of the product line of this embodiment, the power for moving forward is first provided by the conveying mechanism 51 and then by the traction mechanism 51. Since the conveying mechanism 51 is subjected to surface contact force, compared with the line contact force of the traction roller group 51, the uniform force can effectively reduce the risk of product damage and can assist the operation of the product line.

The conveyor belt 32 is located in the box body and is used to convey the molded soft film at a predetermined conveying speed to ensure sufficient curing.

[0046] In this embodiment, when the production line enters the heat curing machine through the laminating calender, the product line is still in a rubber state and needs to be heated and heat-cured in the heat curing machine before it can be formed. In order to ensure the heat curing effect, the length of the heat curing machine sometimes even reaches 13 meters. In this case, the product line is very likely to be deformed due to the influence of gravity. The conveyor belt 32 maintains the same speed as the horizontal product line to provide support for the horizontal product line and avoid defects such as wrinkles.

[0047] Specifically, a partition is provided between the thermal curing machine 3 and the cooling machine 4; a horizontal product line channel is provided on the partition, the horizontal product line channel includes an opening and a shield, the shield is located at the upper part of the opening, and the product line channel also includes a supporting device, the supporting device is provided at the bottom of the horizontal product line to provide vertical support for the horizontal product line;

The supporting device includes multiple rollers for rolling the product line to avoid damaging the surface of the soft film. The supporting device is a detachable connection, preferably a rivet connection.

[0050] The partitions and product line channels implemented in this embodiment can effectively avoid the adverse effects of the high-temperature thermal curing process of the soft film on the subsequent cooling process, while ensuring the smooth operation of the product line and facilitating continuous production.

[0051] Specifically, the laminating calender 2 is further provided with a laminating mechanism 22; the laminating mechanism 22 comprises a roller set symmetrically arranged relative to the product line, wherein the diameter of the upper roller of the roller set is smaller than the diameter of the lower roller, and is used to provide vertical pressure for the product line.

The calendering roller group includes two rollers symmetrically arranged relative to the product line. The rollers can move relative to each other. The calendering force on the film can be adjusted by adjusting the distance between the roller groups to adjust the thickness of the film. The calendering roller group is made of metal, preferably steel. The deadweight of the steel can provide sufficient calendering force.

[0057] More specifically, the guiding mechanism 53 includes an ultrasonic detector for detecting the traveling direction of the product line. When the product line deviates from the preset track, the ultrasonic detector will issue an abnormal alarm;

[0058] More specifically, the guide mechanism 53 further includes a bracket and a plurality of guide rollers, and the product line passes through the guide rollers; at least two guide rollers are detachably connected to the lower side of the bracket, and at least one guide roller is detachably connected to the upper side of the bracket; the guide rollers located on the upper side of the product line and the guide rollers on the lower side are staggered, and the product line sequentially passes through the bottom of the lower guide roller located at the front end of the guide mechanism 53, the top of the upper guide roller, and the bottom of the lower guide roller located at the rear end of the guide mechanism 53.
