Detailed Embodiments

[0053] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0054] An embodiment of the present application provides a temperature control system for a tire spraying production line, as Figure 1 and Figure 2 shown, including:

[0055] A carrying and transporting unit 100 for carrying and transporting tire films on the spraying production line, where the tire films include treads or sidewalls;

[0056] A spraying unit 200 includes a plurality of spray heads 3, and each spray head 3 is distributed above the carrying and transporting unit 100 along the carrying and transporting direction. The spraying unit 200 is used for spraying coolant to reduce the temperature of the tire film during the carrying and transporting process;

[0057] A temperature detection unit 300 includes a plurality of temperature detection elements 2, and each temperature detection element 2 is alternately arranged with the spray head 3 in the carrying and transporting direction. The temperature detection unit 300 is used for detecting the temperature of the tire film during the carrying and transporting process;

[0058] A control unit 400 is used for:

[0059] When receiving the first temperature sent by the current temperature detection element during the carrying and transporting process, determining whether the first temperature is greater than a preset temperature upper limit;

[0060] If so, controlling the target spray head corresponding to the current temperature detection element to open;

[0061] Taking the first temperature detection element located after the current temperature detection element in the carrying and transporting direction as the new current temperature detection element, and obtaining the new first temperature;

[0062] Wherein, the target spray head is the first spray head located after the current temperature detection element in the carrying and transporting direction.

[0063] In the embodiment of the present application, the transmission path type of the carrying and transporting unit 100 can be selected as needed, such as a straight line type or a curve type. When the tire film is transported on the carrying and transporting unit 100, each temperature detection element 2 in the temperature detection unit 300 sends the detected temperature to the control unit 400, and the control unit 400 controls each spray head 3 in the spraying unit 200 according to the temperature to accurately control the offline temperature of the tread / sidewall of the tire. The coolant can be water or other cooling media.

[0064] The control unit 400 obtains the first temperature during the transportation process from the current temperature detection element. If the first temperature is greater than the preset upper temperature limit, it indicates that the temperature of the tire film is too high and cooling is required. The control unit opens the target spray head corresponding to the current temperature detection element. The target spray head is the first spray head located after the current temperature detection element in the transportation direction. The tire film continues to be transported in the transportation direction. The control unit 400 takes the next temperature detection element as the new current temperature detection element, obtains the new first temperature, and re-determines whether the new first temperature is greater than the preset upper temperature limit.

[0065] It can be understood that if the first temperature is not greater than the preset upper temperature limit, the control unit 400 keeps the target spray head closed, thereby avoiding unnecessary opening and saving coolant.

[0066] In order to facilitate the operator to observe the production line status at any time, in some embodiments of the present application, the transportation unit 100 is designed to be open-air.

[0067] In order to improve the reliability of the spraying unit 200, in some embodiments of the present application, as Figures 2 - 4 shown, the spraying unit 200 further includes:

[0070] The first liquid storage tank 7, which is used to store the coolant pumped by the first cooling pump 6;

[0071] The cooling device 8, which is used to cool the coolant flowing in from the first liquid storage tank 7 and input the cooled coolant into the second liquid storage tank 9;

[0072] The second liquid storage tank 9, which is used to supply the cooled coolant to the second cooling pump 10;

[0073] The second cooling pump 10, which is used to pump the coolant in the second liquid storage tank 9 into the coolant inlet 5;

[0074] Among them, the outlet of the first cooling pump 6, the first liquid storage tank 7, the cooling device 8, the second liquid storage tank 9 and the inlet of the second cooling pump 10 are connected in sequence. The inlet of the first cooling pump 6 is connected to the coolant outlet 4, and the outlet of the second cooling pump 10 is connected to the coolant inlet 5.

[0075] In this embodiment, the coolant sprayed by each spray head 3 is recycled to the coolant outlet 4. The first cooling pump 6 provides power to pump the coolant at the coolant outlet 4 into the first liquid storage tank 7. After being cooled by the cooling device 8, it enters the second liquid storage tank 9. The second cooling pump 10 provides power to pump the coolant into the coolant inlet 5. Then the coolant enters the coolant pipeline 11, thus realizing the recycling of the coolant, saving the coolant, and further saving costs.

[0076] Optionally, in order to ensure the cleanliness of the coolant and avoid clogging the spray head 3, in some embodiments of the present application, the spraying unit 200 further includes:

[0077] A filtering device, which is arranged between the coolant outlet 4 and the first cooling pump 6 and is used to filter the coolant at the coolant outlet 4.

[0078] In order to improve the reliability of the carrier transmission unit 100, in some embodiments of the present application, as Figure 2 shown, the carrier transmission unit 100 includes:

[0079] A carrier transmission surface formed by a plurality of drive rollers 1;

[0080] A chain belt for driving each drive roller 1 to rotate;

[0081] A motor for driving the chain belt to rotate.

[0082] Those skilled in the art can adopt other transmission structures according to actual needs, which does not affect the protection scope of the present application.

[0083] In order to improve the reliability of the system, in some embodiments of the present application, the materials of the drive roller 1 and the spray head 3 are both 304 stainless steel.

[0084] Those skilled in the art can adopt other types of materials according to actual needs, which does not affect the protection scope of the present application.

[0086] In order to improve the reliability of the system, in some embodiments of the present application, as Figures 2 - 4 shown, the carrier transmission unit 100 includes a first part and a second part with equal transmission distances, and the spraying unit 200 includes two groups, and each group of spraying units 200 is respectively matched with the first part and the second part.

[0092] Wherein, the target spray head is the first spray head after the current temperature detection element in the conveying and transporting direction.

[0093] In order to perform more accurate temperature control, in some embodiments of the present application, after the control unit obtains the new first temperature, the method further includes:

[0094] If the new first temperature is greater than the preset upper temperature limit, the control unit opens the new target spray head corresponding to the new current temperature detection element;

[0095] If the new first temperature is not greater than the preset upper temperature limit, the control unit closes the target spray head.

[0096] In this embodiment, if the new first temperature is greater than the preset upper temperature limit, it indicates that the temperature of the tire film is still relatively high and further cooling is required. The control unit activates the new target sprinkler head corresponding to the new current temperature detection element. If the new first temperature is not greater than the preset upper temperature limit, it indicates that the temperature of the tire film is not high and further cooling is not required.
