The circumferential direction of the box body is sequentially provided with a flue gas inlet, a medium inlet, a flue gas outlet and a medium outlet. The flue gas inlet and the flue gas outlet are communicated, and the medium inlet and the medium outlet are communicated. Because the box body for cooling is arranged, the flue gas can be effectively heat exchanged through the box body, so that the heat can be recovered and the cooling and forming of the rubber strip can be accelerated.

[0025] Please refer to Figures 1-4 ,

[0026] Example 1: A cooling device for EPDM rubber strip production includes a rubber strip cooling chamber 1. Support legs 2 are evenly arranged around the bottom of the rubber strip cooling chamber 1. A chamber opening closing door 3 is rotatably arranged on the side of the rubber strip cooling chamber 1. Several air outlet channels 4 are symmetrically opened on both sides of the rubber strip cooling chamber 1. Dustproof nets 5 are arranged on each air outlet channel 4. Several rubber strip support components 6 are evenly arranged inside the rubber strip cooling chamber 1. Rubber strip cooling components 7 are arranged on the side of the rubber strip support components 6.

[0027] The adhesive strip support assembly 6 includes support bars 601 symmetrically fixed on both sides of the inner wall of the adhesive strip cooling chamber 1. The top of the support bars 601 is provided with an adhesive strip support mesh plate 602. The top of each support bar 601 is provided with a limiting groove 603. Two limiting sliders 604 are symmetrically arranged on both sides of the bottom end of the adhesive strip support mesh plate 602. The limiting sliders 604 are slidably inserted into the limiting grooves 603. A number of partition plates 605 are evenly arranged on the adhesive strip support mesh plate 602.

[0028] The rubber strip cooling assembly 7 includes two sets of air duct fixing rods 701 symmetrically fixed to the inner wall of the rubber strip cooling chamber 1. Several cooling air supply pipes 702 are evenly fixed on the air duct fixing rods 701. One end of the cooling air supply pipe 702 passes through the air duct fixing rod 701 and the rubber strip cooling chamber 1. Several air outlets 703 are evenly opened on the upper and lower sides of the cooling air supply pipe 702. An air intake groove 704 is provided on the outer side of the rubber strip cooling chamber 1. The end of the cooling air supply pipe 702 is connected to the air intake groove 704. An air inlet chamber 705 is provided on the side of the rubber strip cooling chamber 1. The end of the air intake groove 704 is connected to the air inlet chamber 705. Two fan mounting ports 706 are symmetrically opened on the side of the air inlet chamber 705. Cooling fans 707 are installed on each fan mounting port 706. Two bottom support plates 708 are symmetrically arranged on both sides of the bottom of the air inlet chamber 705.

[0029] Example 2: The difference between this example and Example 1 is that two handles are symmetrically arranged at the end of the rubber strip supporting the mesh plate 602.

[0030] This makes it easier for users to pull out the rubber strip supporting the mesh plate 602.

[0031] Example 3: The difference between this example and Example 1 is that a filter screen is provided at the connection between the air duct 704 and the air inlet chamber 705.

[0032] This ensures that the cold air passing through the air duct 704 is effectively filtered, preventing impurities in the air from entering the rubber strip cooling chamber 1.

[0033] Example 4: The difference between this example and Example 1 is that the longitudinal section of the air duct 704 is trapezoidal.

[0034] The air intake area at the end of the air intake slot 704 is effectively increased, so that when the cooling fan 707 is running, it can quickly blow cold air from the outside into the air intake slot 704.

[0035] In this embodiment, existing rubber strip cooling devices typically use water cooling in actual use. However, water cooling can easily leave water stains on the surface of the rubber strip, requiring further processing. It is also not suitable for some production processes that have high requirements for the surface of the rubber strip, and thus has its drawbacks.

[0036] In summary, during implementation, when a user needs to cool down EPDM rubber strips, the user can first open the compartment door 3 and pull the rubber strip support mesh plate 602 in the rubber strip support assembly 6. Since the two sides of the bottom end of the rubber strip support mesh plate 602 slide in the limiting groove 603 through the limiting slider 604, the rubber strip support mesh plate 602 can be pulled out of the rubber strip cooling chamber 1 more easily. The user can then place the EPDM rubber strips to be cooled on the top of the rubber strip support mesh plate 602, separated by several partition plates 605. After evenly placing the EPDM rubber strips, push them back into the rubber strip cooling chamber 1.

[0037] At this time, the user can start the cooling fan 707 in the rubber strip cooling component 7. After the cooling fan 707 is started, it can blow cold air into the air inlet chamber 705. The side of the air inlet chamber 705 is connected to several cooling air supply pipes 702 through the air duct 704, so that the cold air is blown into the cooling air supply pipes 702 one by one, and then blown to both sides of the EPDM rubber strip placed on the rubber strip support mesh plate 602 through several air outlets 703 set on the cooling air supply pipes 702.

[0038] It can rapidly cool down the entire EPDM rubber strip, and can cool down each part of the EPDM rubber strip at the same time, which greatly reduces the time required to cool down the EPDM rubber strip, improves its overall cooling efficiency, and does not leave water stains on its surface. It can be used for both ordinary and more demanding rubber strip cooling needs, and meets the cooling needs of users.
