In the description of the embodiments of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0025] See also Figures 1 to 5In one embodiment, a rubber-metal composite plate coil production system disclosed herein comprises a winding and unwinding device, an adhesive extrusion device 4 and a vulcanization drying tunnel 5. The winding and unwinding device comprises a winding device 1 and a winding device 2. The winding device 1 is arranged at the starting end of the production system, and is used to support and install a rolled metal substrate 3 for production, and to control the winding speed of the metal substrate 3 coil during production. The winding device 2 is arranged at the end of the production system, and is used to roll the finished rubber-metal composite plate 8 that has been vulcanized at high temperature for storage and transportation. The winding device 2 provides traction power during production through a rotating device (not shown) that drives a power. Both the winding device 1 and the winding device 2 are prior art equipment, and they have The structure of the body is not repeated; the extrusion adhesive device 4 includes an extruder 401 and an adhesive die 402, the adhesive die 402 is installed on the extruder 401, the adhesive die 402 includes an upper die portion 403 and a lower die portion 404, a gap 405 is provided between the upper die portion 403 and the lower die portion 404 for the metal substrate 3 unwound from the unwinding device 1 to pass through, and a rubber flow channel 406 connected to the gap 405 is provided on the upper die portion 403 and the lower die portion 404, respectively, and one end of the rubber flow channel 406 is connected to the extrusion port 407 on the extruder 401, and the vulcanization drying tunnel 5 includes a drying tunnel box 501 and a conveyor belt 502, and the conveyor belt 502 is arranged on the drying tunnel The box 501 is used to lift the rubber-metal composite plate 8 passing through the oven box 501 for vulcanization, so as to prevent the rubber-metal composite plate from shaking and scratching the rubber layer during the vulcanization transmission in the vulcanization oven 5. Specifically, the conveying speed of the conveyor belt 502 is consistent with the traction movement speed of the rubber-metal composite plate 8, so as to avoid the friction and scratches caused by the relative movement between the rubber-metal composite plate 8 and the conveyor belt 502 due to the speed difference. Of course, the conveyor belt 502 can also be replaced by a conveying roller. In this embodiment, the extruder 401 plasticizes the mixed rubber, and then extrude it through the extrusion port 407 into the rubber flow channel 406 corresponding to the upper die portion 403 and the lower die portion 404 respectively. At the same time, the unwinding device 1 unwinds the metal substrate 3 to be coated with glue, and the winding device 2 performs winding and traction. When the metal substrate 3 passes through the gap 405 between the upper die portion 403 and the lower die portion 404, the extruded mixed rubber material is uniformly coated on the upper and lower surfaces of the metal substrate 3 from the upper and lower independent rubber flow channels 406 to attach glue, ensuring that the thickness of the glue film on the upper and lower surfaces of the metal substrate 3 is consistent. The rubber-metal composite plate 8 after adhesive attachment enters the vulcanization drying tunnel 5 for high-temperature vulcanization and is then wound onto the winding device 2 to complete the production. The entire production process has a simple process route and high production efficiency, does not require the use of organic solvents, and does not require calendering facilities, has little pollution to the environment, requires little facility investment, and effectively reduces production costs.

[0026] In a preferred embodiment, the disclosed rubber-metal composite sheet coil production system further includes a first auxiliary roller 6, which is disposed between the extrusion adhesive device 4 and the vulcanization drying tunnel 5. After the metal substrate 3 is glued by the extrusion adhesive device 4, it passes through the first auxiliary roller 6 and enters the drying tunnel box 501 of the vulcanization drying tunnel 5 for vulcanization. The first auxiliary roller 6 limits the rubber-metal composite sheet 8 that has just been glued, ensuring its transmission stability and preventing the rubber-metal composite sheet 8 from shaking during the traction process, which affects the effect of the extrusion adhesive.

[0027] In a preferred embodiment, the disclosed rubber-metal composite sheet coil production system further includes a second auxiliary roller 7, which is disposed between the winding device 2 and the vulcanization drying tunnel 5. After the rubber-metal composite sheet 8 comes out of the vulcanization drying tunnel 5, it passes through the second auxiliary roller 7 and enters the winding device 2 for winding. The second auxiliary roller 7 limits the newly vulcanized rubber-metal composite sheet 8 to ensure its stability in transmission in the drying tunnel box 501, and prevents the rubber-metal composite sheet 8 from shaking during the traction process, scratching the rubber layer 9, and affecting the vulcanization effect.

[0028] In a specific example, wear-resistant blocks 408 are provided at both ends of the gap 405. The distance between the two wear-resistant blocks 408 corresponds to the width of the metal substrate 3. The wear-resistant blocks 408 limit the metal substrate 3 from shaking left and right when the adhesive is attached in the gap 405, thus affecting the adhesive attachment effect.

[0029] In a specific example, a rubber leakage port 409 is provided between the wear-resistant stopper 408 at one end away from the extruder 401 and the upper die portion 403 and the lower die portion 404. When the rubber material accumulates and stays in the rubber flow channel 406 for too long, the rubber material can flow out from the rubber leakage port 409, thereby preventing the rubber material from staying in the rubber flow channel 406 for a long time to generate scorched particles, which may cause quality problems in the extruded rubber-metal composite plate 8.

[0030] In a specific example, flow regulating ports 4010 are respectively provided on one side of the upper die portion 403 and the lower die portion 404 close to the extruder 401, and the flow regulating ports 4010 penetrate into the corresponding rubber flow channel 406, and a flow regulating bolt 4011 is provided in the flow regulating port 4010. By turning the flow regulating bolt 4011, the bottom end of the flow regulating bolt 4011 extends into the rubber flow channel 406, thereby adjusting the channel opening size of the rubber flow channel 406 to adjust the flow, so that the flow of the rubber in the rubber flow channel 406 of the upper die portion 403 and the lower die portion 404 can be controlled to be consistent, so as to control the thickness of the adhesive on the upper and lower sides of the metal substrate 3 to be the same.

[0031] In a specific example, a temperature control water channel 4012 is provided on the upper mouth portion 403 and the lower mouth portion 404 respectively. The temperature control water channel 4012 is connected to an external cooling water source. The cooling water flow entering the temperature control water channel 4012 is controlled to adjust the temperature of the rubber entering the rubber flow channel 406 of the upper mouth portion 403 and the lower mouth portion 404, thereby ensuring that the rubber can be effectively attached to the metal substrate 3.

[0032] In a preferred embodiment, the rubber flow channel 406 includes a main flow channel 4061 and a side flow channel 4062, the main flow channel 4061 and the side flow channel 4062 are connected, and the vertical sections of the main flow channel 4061 and the side flow channel 4062 are in a "comma" structure. When the metal substrate 3 is wider, the rubber flow channel 406 is relatively long. The conventional flow channel design will cause difficulty in the flow of the rubber, and the pressure difference between the front and the back is too large, resulting in uneven thickness of the rubber film; and by setting the vertical section of the rubber flow channel 406 to a "comma" structure, the head of the "comma", that is, the main flow channel 4061, has a larger inner diameter, which is conducive to the flow of the rubber and ensures smooth flow of the rubber. The tail of the "comma", that is, the side flow channel 4062, has a smaller inner diameter, which is conducive to uniformly dispersing the pressure of the rubber, so that the rubber fluid is evenly attached to the metal substrate 3.

[0033] An embodiment of the utility model further discloses a rubber-metal composite plate 8, which is produced by the above-mentioned rubber-metal composite plate coil production system. The rubber-metal composite plate 8 includes a metal substrate 3 and a rubber layer 9, and the upper and lower surfaces of the metal substrate 3 are coated with the rubber layer 9.

[0034] In a preferred embodiment, the material of the metal substrate 3 is any one of stainless steel plate, cold-rolled plate, and copper plate, preferably stainless steel plate, and the material of the rubber layer 9 is any one of nitrile rubber, fluororubber, and EPDM rubber, preferably nitrile rubber.

[0035] When the rubber-metal composite plate coil production system of the utility model is used to produce the rubber-metal composite plate 8, the mixed rubber used for production and the metal substrate 3 coil for the adhesive are first prepared, the metal substrate 3 and the traction plate are spliced ​​and passed through the gap 405 between the upper die portion 403 and the lower die portion 404, the extrusion temperature of the extruder 401 is set, the temperature of the adhesive die 402 is set, the vulcanization drying tunnel 5 is turned on and the drying tunnel temperature is set, and after the temperatures of the extruder 401, the adhesive die 402 and the vulcanization drying tunnel 5 meet the process requirements, the prepared rubber strip is fed into the extruder 401, the adhesive die 402 and the vulcanization drying tunnel 5. The rubber material flows out of the rubber discharge port 409 on 402, and the metal substrate 3 is unwound by the traction plate into the gap 405 to start extruding the attached rubber. The attached rubber is extruded for about 1 meter, and the appearance and thickness of the attached rubber layer 9 are inspected. If it is within the qualified range, continuous extrusion production can be started. If it is not within the qualified range, the flow rate (extrusion speed) of the rubber flow channel 406 and the traction speed of the metal substrate 3 are adjusted until it is qualified. When the extruded rubber-metal composite plate 8 passes through the vulcanization drying tunnel 5 for high-temperature vulcanization, it is inspected online. If the product is qualified, production continues, and the rubber-metal composite plate 8 is rolled up to the winding device 2 for storage.
