[0032] like Figure 1 As shown, an embodiment of the utility model provides a hot air drying device for a cylinder cleaning machine, comprising a turning roller 1 and a blower mechanism 2 arranged around the turning roller 1 .

[0033] The turning roller 1 is fixedly connected to a turning mechanism 3, and the turning mechanism 3 drives the turning roller 1 to rotate. The turning mechanism 3 is provided with a clamp 4 corresponding to the turning roller 1.

[0034] In actual operation, the hot air drying device for the cylinder cleaning machine provided by the embodiment of the utility model has the two ends of the turning roller 1 connected to the corresponding transport rollers of the production line to form a complete roller, or directly connect the upper and lower processes. The cylinder is transported to the turning roller 1 from the previous process through the transport roller, and the clamp 4 provided by the turning mechanism 3 cooperates with the turning roller 1 to clamp the cylinder, and then the turning mechanism 3 drives the turning roller 1 together with the cylinder fixed thereto to start turning over. During the turning process, the blower mechanism 2 blows air to the cylinder to dry it. Because the cylinder is turned over during the drying process, the water retained inside can be poured out to the greatest extent, and the cylinder can be blown dry from all angles, which can solve the problem of part of the workpiece not being dried. In addition, since the workpiece rotates together with the turning roller 1 during the drying process, it is not restricted by the machine model, can be compatible with various machine models, and reduces production costs.

Since the flip roller 1 is fixedly connected to the driving turntable 31, when the driving turntable 31 rotates, the flip roller 1 and the cylinder body fixed thereto by the clamp 4 can be driven to rotate synchronously. The rotation driving device can be a combination of a motor 34 and a reducer 35, the output shaft of the motor 34 is connected to the input shaft of the reducer 35, and the output shaft of the reducer 35 is fixedly connected to the driving gear 33. The driving turntable 31 and the driven gear 32 are provided with a first through hole 311 for the cylinder body to pass through, and the cylinder body can enter the flip roller 1 from the first through hole 311. In this embodiment, the driven gear 32 is annular, and only the first through hole 311 is provided on the driving rotary disk 31 .

[0036] Furthermore, in order to make the turning roller 1 rotate more smoothly during the turning process, Figure 1 As shown, the turning mechanism 3 further includes a driven turntable 36, which is arranged opposite to the driving turntable 31. The two ends of the turning roller 1 are fixedly connected to the driving turntable 31 and the driven turntable 36 respectively. The driven turntable 36 is provided with a second through hole 361 for the cylinder body to pass through. The cylinder body can enter the turning roller 1 from the first through hole 311, and after turning, blowing, drying and resetting, it can leave from the second through hole 361 to the transport roller of the next process.

[0037] In one embodiment of the present invention, Figure 2-Figure 5As shown, the hot air drying device of the cylinder cleaning machine also includes a shell 5, which covers the turning roller 1 and the blower mechanism 2, which can not only prevent external pollutants from entering the cylinder, but also save the blowing amount of the blower mechanism 2, especially when using hot air to dry, the temperature of the hot air can be maintained to improve the drying effect. The shell 5 is provided with third through holes 51 for the cylinder to pass through on both sides, which correspond to the first through hole 311 and the second through hole 361 respectively. The driving turntable 31 and the driven turntable 36 are respectively arranged on the two opposite inner walls of the shell 5, and the inner wall of the shell 5 is provided with a plurality of support bearings 6 corresponding to the outer periphery of the driving turntable 31 and the driven turntable 36, and the driving turntable 31 and the driven turntable 36 are supported and fixed on the inner wall of the shell 5 by each support bearing 6. The support bearing 6 can rotate relative to the driving turntable 31 and the driven turntable 36. When the driving turntable 31 and the driven turntable 36 rotate, the wear between the support bearing 6 can be reduced and the service life can be extended.

[0038] Specifically, if Figure 6 As shown, the support bearing 6 includes a support shaft 60 that penetrates the side wall of the housing 5, and the support shaft 60 is sequentially sleeved with a first sleeve 61, a second sleeve 62, and a third sleeve 63. The first sleeve 61, the second sleeve 62, and the third sleeve 63 can rotate around the support shaft 60. The second sleeve 62 is arranged in the side wall of the housing 5, and the third sleeve 63 is fixedly connected to the outer wall surface of the housing 5, and is used to fix the support bearing 6 on the side wall of the housing 5. The first sleeve 61 is against the outer periphery of the driving rotary disk 31 and the driven rotary disk 36, and is used to support the driving rotary disk 31 and the driven rotary disk 36, and realizes relative rotation between the first sleeve 61 and the driving rotary disk 31 and the driven rotary disk 36. In order to limit the axial displacement of the driving turntable 31 and the driven turntable 36 on the support shaft 60 , a limit plate 64 is provided at one end of the support shaft 60 located in the shell 5 . The limit plate 64 is located on the side of the driving turntable 31 and the driven turntable 36 away from the second sleeve 62 .

[0039] In one embodiment of the utility model, the blower mechanism 2 includes a plurality of air knives 21, which are arranged on the inner wall of the housing 5. The air knives 21 are connected to an air source, preferably a hot air source, to quickly dry the cylinder body. The hot air drying device for the cylinder cleaning machine provided by the utility model embodiment eliminates the original cleaning nozzle and some air knives, thereby reducing energy consumption.

[0040] In one embodiment of the utility model, the inner wall of the shell 5 is provided with an in-position sensor 7, which can detect whether the cylinder body enters the predetermined position on the turning roller 1. After the cylinder body is in position, the in-position sensor 7 sends a signal to start the turning and drying process.

[0041] In one embodiment of the utility model, the clamp 4 includes a mounting plate 41, a cylinder 42 and a clamping plate 43. The mounting plate 41 is arranged between the driving turntable 31 and the driven turntable 36, the cylinder 42 is fixedly arranged on the mounting plate 41, and the clamping plate 43 is arranged at the end of the piston rod of the cylinder 42, and is used to cooperate with the turning roller 1 to press the cylinder body. The hot air drying device of the cylinder cleaning machine provided by the utility model embodiment, because the turning roller 1 rotates together with the cylinder body, only one set of clamps is arranged above the turning roller 1 to cooperate with the turning roller 1 to clamp the cylinder body, and there is no need to arrange multiple sets of clamps, the internal space of the shell 5 is improved, and the production cost is reduced at the same time, and the convenience of maintenance is greatly improved.

[0042] Furthermore, the cylinder 42 is provided with a locking device. After the piston rod of the cylinder 42 extends out to press the workpiece, the locking device starts to work, and the workpiece will not fall during the flipping process together with the flip roller 1. After drying, the locking device is unlocked, the cylinder piston rod retreats to release the workpiece, and the drying process is completed.

[0043] In actual operation of the hot air drying device for the cylinder cleaning machine provided by the embodiment of the utility model, when the in-place sensor 7 detects that the workpiece is in place on the flip roller 1, the piston rod of the cylinder 42 extends downward to cooperate with the flip roller 1 to clamp the workpiece, and the wind knife 21 starts to blow air. After the blowing signal is activated, the motor 34 is started to rotate the driving turntable 31 and the driven turntable 36, synchronously driving the flip roller 1 and the workpiece to rotate, and the clamp 4 is also fixed on the driving turntable 31 and the driven turntable 36, so the clamp 4 also rotates with the driving turntable 31 and the driven turntable 36 to keep the workpiece clamped. When the workpiece rotates forward to a certain position, the sensor sends a signal, the motor 34 stops and then rotates in the reverse direction. During this process, the wind knife 21 will blow the workpiece with hot air in all directions. After the reverse rotation is completed, the motor 34 drives the flip roller 1 back to the initial position, and the workpiece completes one drying and begins to flow into the next station.

[0044] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes.
