DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] In the description of the present invention, it should be understood that the terms "middle", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0028] In this utility model, unless otherwise specified or limited, the terms "disposed," "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed or detachable connections, mechanical connections, direct connections, or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0029] like Figure 1As shown, a tire tread rubber cooling device includes a water tank 1 and multiple conveying rollers 2 arranged in parallel in the water tank. Each conveying roller includes a roller 201 and a positioning shaft 202. The roller is sleeved on the outside of the positioning shaft and is rotatably connected to the positioning shaft through a bearing. Each positioning shaft is detachably connected to a positioning seat 3 provided on the inner wall of the water tank. Figure 3 As shown, both ends of the positioning shaft are connected to positioning blocks 203. The positioning blocks are connected to positioning grooves 301 provided on the corresponding positioning seats. A positioning screw 6 is connected between the positioning blocks and the positioning grooves. The positioning screw passes through the positioning blocks and connects to the threaded holes provided on the bottom wall of the positioning grooves, thereby securing the positioning blocks to the positioning grooves. When the thickness of the tread rubber is relatively thin, the number of conveying rollers can be appropriately reduced. As the tread rubber passes through each conveying roller in sequence, its length and soaking time in the water tank will also be reduced accordingly. Conversely, when the thickness of the tread rubber is relatively thick, the number of conveying rollers can be appropriately increased, allowing the tread rubber to pass through each conveying roller in sequence, thereby extending its length and soaking time in the water tank to meet the cooling requirements of the tread rubber of different products. One side of the water tank is connected to an inlet pipe 4, and the bottom side of the water tank is connected to an outlet pipe 5. Control valves 9 are installed on both the inlet and outlet pipes. The flow direction of the cooling water is opposite to the conveying direction of the tread rubber to improve the cooling effect. A drainage trough 10 is provided at the connection between the bottom of the sink and the outlet pipe. The drainage trough is in the shape of an inverted cone, and a filter screen 11 is embedded on its top. The filter screen can filter impurities in the water to prevent pipe blockage. The filter screen can be disassembled regularly for replacement or cleaning.

[0030] like Figure 1 As shown, the multiple conveyor rollers include an upper roller group and a lower roller group arranged parallel to each other. The conveyor rollers of the upper roller group are alternately spaced. In this embodiment, the upper roller group includes five conveyor rollers and the lower roller group includes four conveyor rollers. The specific number of conveyor rollers can be increased or decreased according to actual needs. At least two active rollers 7 are rotatably connected within the water tank. One end of each active roller is connected to a first drive motor 8. When necessary, the tread rubber 26 can be passed around the active rollers. The first drive motor drives the active rollers to rotate, providing power for the tread rubber conveying. The active rollers are located below the lower roller group. When not in use, they do not affect the conveying of the tread rubber.

[0031] like Figure 4As shown, a support rod 22 is provided at the upper end of the water trough, which spans the upper end of the water trough. Two sleeves 23 are mounted on the support rod. Each sleeve is slidably connected to the support rod, and a locking screw 24 is threaded onto the sleeve. A guide rod 25 is connected to the lower end of each sleeve. Tightening the locking screw secures the sleeve to the support rod. The locking screw passes through one side wall of the sleeve and contacts the upper end face of the support rod. The distance and position between the two sleeves and the guide rod are adjusted according to the width of the tread rubber, which serves as a guide for the tread rubber conveying. To improve the stability of the tread rubber conveying, two parallel guide rollers 12 are rotatably mounted on the upper end of one side of the feed end of the water trough. The two guide rollers are located in the same horizontal plane.

[0032] like Figure 1 and Figure 2 As shown, two groups of squeezing mechanisms are spaced apart at the upper end of one side of the discharge end of the water trough along the tread rubber conveying direction, which can squeeze and remove water from the cooled tread rubber. Each group of squeezing mechanisms includes a fixed frame 13, a cylinder 14, an upper squeezing roller 15, and a lower squeezing roller 16. The fixed frame is provided with a lifting rail 17, and a lifting seat 18 is slidably connected to the lifting rail. The cylinder is installed at the top of the fixed frame and connected to the lifting seat. The upper squeezing roller is rotatably connected to the lifting seat. The lower squeezing roller is located below the upper squeezing roller and is rotatably connected to the fixed seat 19 provided on the fixed frame. One end of the lower squeezing roller is connected to a second drive motor 20. The cylinder is used to adjust the height of the upper squeezing roller to control the distance and squeezing force between it and the lower squeezing roller to meet the squeezing requirements of tread rubber of different thicknesses. The bottom of the lifting rail is provided with a limit block 21 that cooperates with the lifting seat to ensure the stability of the fixed seat. The two sets of water squeezing mechanisms can effectively improve the water squeezing effect. A synchronous wheel 27 is provided at the end of the lower squeezing roller of each set of water squeezing mechanisms. A synchronous belt 28 is connected between the two synchronous wheels to achieve synchronous rotation. One of the lower squeezing rollers is connected to the second drive motor through a sprocket chain transmission mechanism, thereby providing power for the tread rubber to be transported.

[0033] The cooling water in the present invention reaches the required process temperature through heat exchange in a cooler (existing technology, not shown in the figure), which not only realizes automatic control but also has small temperature fluctuations, ensuring good cooling effect of the tread rubber and uniform shrinkage consistency, and can minimize the length of the cooling water tank and reduce the equipment footprint.

[0034] The working principle of this utility model is as follows:

[0035] During use, the tread rubber 26 first passes around the two guide rollers 12 in sequence before entering the water tank 1 and being immersed in cooling water. The connection relationship between the tread rubber 26 and the conveying rollers 2 and the active roller 7 inside the water tank 1 can be freely selected according to the actual thickness of the tread rubber. When the tread rubber thickness is large, it can be selected to pass around more conveying rollers to extend its conveying path and soaking time; conversely, when the tread rubber thickness is small, fewer conveying rollers can be selected. Cooling water enters the discharge end of the water tank 1 and is discharged from the feed end of the water tank. The water flow direction is opposite to the tread rubber conveying direction. The cooled tread rubber enters the two sets of squeezing mechanisms in sequence, passing between the upper squeezing roller 15 and the lower squeezing roller 16 of each set of squeezing mechanisms. The squeezing force is adjusted by the cylinder 14 to achieve the purpose of dehydration, remove excess water from the tread rubber, and facilitate the subsequent drying process.

[0036] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from all perspectives, the embodiments should be regarded as illustrative and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes that come within the meaning and range of equivalents of the claims be included in the present invention.
