Description

Technical Field

[0001] This invention relates to the field of temperature control technology, specifically to a production line temperature control system and its control method. Background Technology

[0002] Currently, tire temperature control systems are inadequate in terms of both intelligence and system completeness. In daily production, temperatures often fall too high or too low, resulting in the final tire tread and sidewall temperatures failing to meet requirements. Furthermore, the common cooling method of water spraying only partially or mostly covers the tread, failing to provide sufficient cooling and hindering temperature control, particularly for the tread and sidewalls. If the final tire's temperature is not properly controlled, it poses a significant safety hazard.

[0003] Based on this, a production line temperature control system and its control method are now provided, which can eliminate the drawbacks of existing equipment. Summary of the Invention

The first gears near the inner sidewall of the fixed box mesh with the rack. The plurality of first gears mesh with each other.

[0011] In one alternative embodiment: the clamping assembly includes a clamping plate, a clamping rod, and a rotating box. A rotating box is fixedly connected to the upper surface of several first gears. A bidirectional screw groove is formed on the upper surface of the rotating box. A bidirectional screw is rotatably connected to the inner sidewall of the bidirectional screw groove through a bearing. Two clamping plates are slidably connected to the inner sidewall of the bidirectional screw groove. The two clamping plates are threadedly connected to the bidirectional screw. A clamping rod is rotatably connected to the opposite sidewall of the two bidirectional screws through a bearing.

[0012] In one alternative: rubber pads are provided on the opposite sidewalls of both clamping rods.

[0013] In one alternative embodiment: the self-rotating assembly includes a fixed block, a second gear, a second rotating shaft, and a friction wheel. Two opposing fixed blocks are fixedly connected to the upper surface of the rotating box. The two fixed blocks are rotatably connected to the second rotating shaft through a bearing.

[0018] Step 2: Start the conveyor roller to transport the tire. The spray pipe contains multiple spray heads and uses coolant to cool the tire tread, thereby achieving temperature control.

[0019] Step 3: When the tire is transported to the temperature detector, the temperature detector transmits the measured temperature to the microcontroller. The microcontroller determines whether the temperature is within the input temperature range. If it is within the temperature range, the spray pipe operates unchanged.

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] In one embodiment, such as Figures 1-5 As shown, the production line temperature control system includes a fixed box 1, which is an open box with a top wall. Several conveyor rollers are arranged on the inner side wall of the fixed box 1, and the several conveyor rollers work together with a conveyor belt. The system is characterized by including a circulation device and a rotation device. Two spray pipes 7 are fixedly connected to the upper surface of the fixed box 1. The rotation device is arranged on the surface of the conveyor belt to increase the tire spraying area. The circulation device is arranged on one side of the fixed box 1 for coolant circulation.

[0033] In one embodiment, such as Figure 1 As shown, the circulation device includes a storage tank 2, a cooler 3, a first water pump 4, a second water pump 5, and a fixed cylinder 6. The fixed tank 1 is connected to the cooler 3 via a water pipe. The cooler 3 is connected to the first water pump 4 via a water pipe. The first water pump 4 is connected to the storage tank 2 via a water pipe. The storage tank 2 is connected to the second water pump 5 via a water pipe. The fixed cylinder 6 is fixedly connected to the upper surface of the fixed tank 1 via a bracket. The second water pump 5 is connected to the fixed cylinder 6 via a water pipe. Two spray pipes 7 are connected to the fixed cylinder 6. When coolant is sprayed into the fixed tank 1, the first water pump 4 is started. The first water pump 4 draws coolant from the fixed tank 1, cools it again through the cooler 3, and then returns it to the first water pump 4 for reuse. The coolant is recycled and reused, saving energy.

[0034] In one embodiment, such as Figure 1 and Figure 2As shown, each of the two spray pipes 7 is equipped with a solenoid valve 8 at the connection point with the fixed cylinder 6. The solenoid valve 8 is electrically connected to the controller. The temperature detector 9 transmits the measured temperature to the microcontroller. The microcontroller determines whether the temperature is within the input temperature range. When the temperature is within the range, the operation of the spray pipe 7 remains unchanged. When the temperature is higher than the input temperature range, the microcontroller issues a command, and the solenoid valves 8 on the spray pipe 7 open one by one, increasing the amount of coolant sprayed until it reaches the maximum spray setting. When the temperature is determined to be lower than the input temperature range, the solenoid valves 8 on the spray pipe 7 close one by one, reducing the amount of coolant sprayed until it reaches the minimum setting.

[0035] In one embodiment, such as Figure 3 As shown, the rotating device includes a revolution component, a rotation component, and a clamping component. The revolution component includes a fixed plate 10, a first rotating shaft 14, a first gear 15, and a rack 26. The fixed plate 10 is fixedly connected to the surface of the conveyor belt. Several first rotating shafts 14 are rotatably connected to the upper surface of the fixed plate 10 via bearings. A first gear 15 is fixedly connected to the end of each first rotating shaft 14 away from the fixed plate 10. A rack 26 is fixedly connected to the inner wall of the fixed box 1. The first gear 15 near the inner wall of the fixed box 1 meshes with the rack 26, and the several first gears 15 mesh with each other. During the tire's transport and being sprayed with coolant, the first gear 15 meshes with the rack 26 and rotates, causing the first gear 15 to rotate the rotating box 16. The rotating box 16 drives the tire to revolution, increasing the tire's spray contact area.

[0036] In one embodiment, such as Figure 5 As shown, the clamping assembly includes clamping plates 12, clamping rods 13, and a rotating box 16. A rotating box 16 is fixedly connected to the upper surface of several first gears 15. A bidirectional screw groove is formed on the upper surface of the rotating box 16. A bidirectional screw 24 is rotatably connected to the inner wall of the bidirectional screw groove via bearings. Two clamping plates 12 are slidably connected to the inner wall of the bidirectional screw groove. The two clamping plates 12 are threadedly connected to the bidirectional screw 24. Clamping rods 13 are rotatably connected to the opposite sidewalls of the two bidirectional screws 24 via bearings. When the tire is placed above the friction wheel 23, the motor 25 is started. The motor 25 drives the bidirectional screw 24 to rotate, which in turn drives the two clamping plates 12 to move towards each other. The clamping plates 12, in turn, drive the two clamping rods 13 to clamp and fix the tire, thus completing the tire positioning.

[0037] In one embodiment, such as Figure 3 and Figure 4 As shown, rubber pads are provided on the opposite sidewalls of the two clamping rods 13 to increase the friction between them and the tire.

[0038] In one embodiment, such as Figure 3As shown, the self-rotating assembly includes a fixed block 18, a second gear 19, a second rotating shaft 20, and a friction wheel 23. Two opposing fixed blocks 18 are fixedly connected to the upper surface of the rotating box 16. The two fixed blocks 18 are rotatably connected to the second rotating shaft 20 through a bearing. The friction wheel 23 is fixedly connected to the part of the second rotating shaft 20 located between two third synchronous pulleys 28. The second gear 19 is fixedly connected to the end of the second rotating shaft 20 away from the fixed block 18. A gear ring 17 is fixedly connected to the upper surface of the fixed plate 10 through a bracket. The second gear 19 meshes with the gear ring 17. The rotating box 16 drives two fixed blocks 18 to revolve, the fixed blocks 18 drive the second rotating shaft 20 to revolve, the second rotating shaft 20 drives the second gear 19 to revolve, the second gear 19 meshes with the gear ring 17 and rotates on its own axis, the second gear 19 drives the second rotating shaft 20 to rotate on its own axis, the second rotating shaft 20 drives the friction wheel 23 to rotate, the friction wheel 23 contacts the tire sidewall and drives the tire to rotate on its own axis, further increasing the spray area, reducing spray dead angles, and making the tire cooling effect better.

[0039] In one embodiment, such as Figure 3 and Figure 5 As shown, the second rotating shaft 20 passes through both clamping plates 12. A spline 21 is provided on the portion of the second rotating shaft 20 that passes through the clamping plates 12. Splined bushings 22 are rotatably connected to both clamping plates 12 via bearings, and the splined bushings 22 and spline 21 are slidably connected through each other. This makes the movement of the clamping plates 12 more stable.

[0040] In one embodiment, such as Figure 1 and Figure 2 As shown, a temperature detector 9 is fixedly connected to the upper surface of the fixed box 1 via a bracket, and the temperature detector 9 is electrically connected to the controller. When the tire is transported to the position of the temperature detector 9, the temperature detector 9 detects the temperature and transmits the data to the microcontroller.

[0041] The above embodiment discloses a control method for the production line temperature control system. First, the tire is placed above the friction wheel 23, and the motor 25 is started. The motor 25 drives the bidirectional screw 24 to rotate. The bidirectional screw 24 drives the two clamping plates 12 to move towards each other. The clamping plates 12 drive the two clamping rods 13 to clamp and fix the tire, thus completing the positioning of the tire.

[0042] The conveyor rollers transport the tires. Spray pipe 7 contains multiple spray heads that cool the tire treads by dispensing coolant, thus achieving temperature control. The controller is a microcontroller. When the tire reaches the temperature detector 9, the detector detects the temperature and transmits the data to the microcontroller. The microcontroller determines whether the tire is within the set temperature range and provides corresponding feedback. It can determine the number of spray heads to activate based on the difference between the actual and set temperatures, minimizing unnecessary activation and saving energy. This operating mechanism can cycle until the standard temperature range is reached, and the coolant is recycled and reused, further saving energy.

[0043] Temperature detector 9 transmits the measured temperature to the microcontroller. The microcontroller determines whether the temperature is within the input temperature range. When the temperature is within the range, the operation of spray pipe 7 remains unchanged. When the temperature is higher than the input temperature range, the microcontroller issues a command, and the solenoid valves 8 on spray pipe 7 open one by one, increasing the amount of coolant sprayed until it reaches the maximum spray setting. When the temperature is determined to be lower than the input temperature range, the solenoid valves 8 on spray pipe 7 close one by one, reducing the amount of coolant sprayed until it reaches the minimum setting.

[0044] The conveyor shaft and conveyor rollers are made of 304 stainless steel, and the pressure rollers are corrosion-resistant, sturdy and durable.

[0045] During the tire's transport and coolant spraying process, the first gear 15 meshes with the rack 26 and rotates, causing the first gear 15 to rotate the rotating box 16. The rotating box 16 drives the tire to revolve, increasing the tire's spray contact area. At the same time, the rotating box 16 drives the two fixed blocks 18 to revolve, the fixed blocks 18 drive the second rotating shaft 20 to revolve, and the second rotating shaft 20 drives the second gear 19 to revolve. The second gear 19 meshes with the gear ring 17 and rotates on its own axis. The second gear 19 drives the second rotating shaft 20 to rotate on its own axis, and the second rotating shaft 20 drives the friction wheel 23 to rotate. The friction wheel 23 contacts the tire sidewall, causing the tire to rotate on its own axis, further increasing the spray area, reducing spray dead zones, and making the tire cooler.

[0046] The coolant is sprayed into the fixed tank 1, and the first water pump 4 is started. The first water pump 4 draws the coolant from the fixed tank 1, passes it through the cooler 3 for further cooling, and then enters the first water pump 4 for secondary use. The coolant is recycled and reused, saving energy.

[0047] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
