Description

Technical Field

[0001] This utility model relates to the field of spraying technology, specifically a vulcanization spraying drive structure. Background Technology

[0002] After the belt is formed by high-temperature vulcanization and molding, it needs to be cooled quickly and wound. In the existing process, the formed belt relies on air cooling. After a period of time, the heat remains in the cooling room, which leads to a high ambient temperature. This makes the subsequent air cooling speed very slow. The high ambient temperature also makes it difficult to meet the process requirements of winding the belt after it is formed.

[0003] Therefore, a rapid cooling method is needed. In practice, spraying is often used for cooling. In actual operation, a section of belt to be cooled needs to be straightened and tightened. Then, the reciprocating drive mechanism drives the nozzle to spray the belt back and forth. Then, the belt is loosened and wound up. During the winding process, the belt will be placed on the spray frame. In this process, the traditional drive mechanism is under increased pressure due to the belt on the frame, which can easily cause the weight to be unbalanced, resulting in misalignment, jamming, and poor movement of the reciprocating motion mechanism.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0023] To address the problems existing in the relevant prior art, this utility model proposes a vulcanization spray driving structure. The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-5 The following specific solution is provided for a vulcanization spray drive structure, including a set of horizontally parallel crossbeams 1. In practical applications, the crossbeams can be a set of I-beams horizontally arranged and supported and fixed by adding support beams at both ends of the I-beams, or they can be fixedly connected to the top of the workshop by hoisting. No specific limitation is made here. A square guide rail 2 is provided on the upper part of the set of crossbeams 1. The guide rail 2 can be fixed to the crossbeams by bolts or by welding. A square transverse frame 3 is horizontally arranged in the middle of the set of guide rails 2. The transverse frame can be formed by welding two sets of square steel of the same length. A vertical spray frame 4 is provided at the lower part of the transverse frame 3. The spray frame 4 is also formed by welding square steel and is in the shape of a cube. The spray frame 4 is provided with nozzles 5. There are at least two sets of nozzles 5, which are arranged facing each other. During use, the belt passes through the middle of one set of nozzles. The belt is cooled by spraying two sets of nozzles on both sides. The lower part of the transverse frame 3 and the guide rail 2 is equipped with four traveling wheels 6, which are symmetrically arranged. The traveling wheels 6 have flanges facing inward, which correspond to the inner side of the guide rail 2. The distance between the two flanges is the same as the distance between the guide rails 2. This ensures that the four traveling wheels are always aligned with the guide rail 2, effectively preventing the eccentric load caused by the sudden increase of external force during operation. The bottom of the transverse frame 3 is also equipped with a drive shaft 7, which is perpendicular to a set of horizontal beams 1. The two ends of the drive shaft 7 are equipped with gears 8. The set of horizontal beams 1 is equipped with racks 9 that mesh with the gears. The transverse frame 3 is also equipped with a motor 10, which is driven by a chain between the motor 10 and the drive shaft 7. The gears 8 and racks 9 are installed on both sides to avoid the asynchronous phenomenon caused by uneven force during forced operation.

[0025] Furthermore, a set of limiting wheels 11 are fixed on the lower part of the side corresponding to the guide rail 2 of the transverse frame 3. The distance between the limiting wheels 11 is the same as the width of the guide rail 2, which can further ensure that the transverse frame 3 and the guide rail 2 are aligned.

[0026] The side of the crossbeam 1 is also provided with a cable chain 12 for fixing the wire harness. The cable chain 12 is connected to the transverse frame 3. The cable chain is used to place the wire harness and the pipeline connecting the nozzle 5.

[0027] The bottom side of the transverse frame 3 and the crossbeam 1 is fixed with a mounting base 13 by bolts. The first bearing 14 is sleeved on the bearing rod 15, the bearing rod 15 is fixed on the mounting base 13, and the traveling wheel 6 is fixed on the first bearing 14.

[0028] The drive shaft 7 and the transverse frame 3 are connected to each other by connecting rods 16. There are at least two connecting rods 16. In this embodiment, there are three connecting rods 16. The three connecting rods 16 are respectively connected to the middle part of the drive shaft 7 and the two ends near the gear 8. This ensures that the drive shaft 7 with a large span is subjected to uniform force and is not prone to deformation. The upper part of the connecting rod 16 is fixedly connected to the transverse frame 3, and the lower part is fixedly equipped with a bearing 17. The drive shaft 7 is fixedly connected to the bearing 17. Both the drive shaft 7 and the end of the motor 10 shaft are equipped with sprockets 18. The two sprockets 18 are connected by a chain.

[0029] One end of the drive shaft 7 is keyed to the corresponding gear 8, and the other end is fixedly connected to the corresponding gear 8 through the shaft end baffle 19 and the tensioning sleeve 20. This makes it easier to fix and install the drive shaft and the gear.

[0030] Meanwhile, the rack 9 has a segmented structure. In this embodiment, the rack 6 has a stroke length of 8-10 meters, and each segment of the rack is 0.5-0.7 meters long. The rack 9 is fixed to the inside of the I-beam with bolts, and the gear 8 is located inside the I-beam and meshes with the rack. In this way, the I-beam can also provide some protection for the meshing part of the gear and rack.

[0031] The specific working principle is as follows: During use, the aforementioned drive structure is installed in the cooling section of the workshop. After the belt is vulcanized, it passes through the middle of a set of nozzles on the spray frame, and the rear end is connected to a winding device. During use, the rear winding device pulls the vulcanized belt, which needs cooling, below the stroke range of the rack 6. Then, the motor drives the transverse frame 3 to reciprocate within the rack's stroke range. Specifically, a reversing switch can be installed at both ends of the rack to switch the motor between forward and reverse rotation, thus achieving the reciprocating motion. This is a common technique in this field and is not specifically limited here. During the reciprocating motion, the nozzles are connected to an external water supply. The pipeline sprays the belt to cool it down. After cooling is complete, the belt is loosened and placed on the spray frame. Then, the rear end is pulled and wound up, while the new vulcanized belt that needs to be cooled is pulled to the lower part of the travel range of rack 6. The spraying operation is repeated. In the above scheme, by using double-sided flanged traveling wheels and adding a horizontal traveling guide wheel on the other side, it is ensured that the traveling wheels and guide rails are aligned even if the external force changes. At the same time, the transmission adopts double-sided gear rack forced synchronization, which also effectively prevents the eccentric load caused by the sudden increase of external force during operation on the traveling and guide wheels.

[0032] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
