[0002] Stainless steel is widely used in industries such as construction, automotive, and aerospace. Its characteristics such as beautiful appearance, corrosion resistance, and easy cleaning make it an ideal material choice. However, during the processing, impurities such as rust and dirt will remain on the surface of stainless steel, affecting its appearance and performance. Therefore, it is necessary to perform pickling treatment on the surface of stainless steel to remove impurities and improve its smoothness and surface quality.

[0003] During the installation of the pickling roller, it is indeed a challenge that needs to be carefully handled when encountering different sizes of pickling roller brackets. The pickling roller is mainly used for rust removal and cleaning of the metal surface, and its size and specifications must match the corresponding brackets to ensure the stability of installation and the smoothness of operation.

[0004] However, the size of the traditional pickling roller cannot be changed and it cannot be installed with brackets of different sizes. As a result, different models of brackets need to be paired with different models of pickling rollers, leading to the need to customize different models of pickling rollers. Summary of the Utility Model

[0023] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0024] Embodiment 1

[0025] The present utility model provides an adjustable stainless steel pickling roller, as Figures 1-7 shown, including: a roller body 1, both end faces of the roller body 1 are fixedly connected with shaft bodies 2, a rotating shaft 3 is movably connected inside the shaft body 2, an iron rod 4 is rotatably connected inside the rotating shaft 3, a first bevel gear 9 is fixedly connected to the surface of the iron rod 4, two second bevel gears 10 are meshed and connected to the surface of the first bevel gear 9, a lead screw 6 is fixedly connected to one end face of each of the two second bevel gears 10, the end of the lead screw 6 away from the second bevel gear 10 is in interference fit inside the roller body 1 through a bearing, a nut 7 is rotationally connected to the surface of the lead screw 6 through a thread, a driving arm 8 is movably connected to one side face of the nut 7, and the end face of the driving arm 8 opposite to the nut 7 is rotatably connected to the surface of the rotating shaft 3.

[0026] As Figures 3 to 6 shown, a second bearing 15 is in interference fit on the surface of the lead screw 6, support rods 5 are symmetrically and fixedly connected to the surface of the second bearing 15, and the end of the support rod 5 away from the second bearing 15 is fixedly connected inside the roller body 1. The lead screw 6 is fixed by the support rod 5. Since the support rod 5 and the lead screw 6 are in interference fit through the second bearing 15, the support rod 5 can fix the lead screw 6 without affecting the rotation of the lead screw 6, thereby making the rotation of the lead screw 6 more stable.

[0027] As Figures 3 to 6 shown, a baffle 13 is fixedly connected inside the roller body 1, first bearings 14 are installed on both the left and right sides of the baffle 13 through interference fit, and first bearings 14 are installed on the surface of the iron rod 4 through interference fit. By interference-fitting the first bearing 14 on the surface of the baffle 13 and interference-fitting the first bearing 14 on the surface of the iron rod 4, the iron rod 4 and the baffle 13 can be effectively fixed without affecting the rotation of the iron rod 4, thereby making the rotation of the iron rod 4 more stable during the rotation process.

[0028] As Figure 3 , Figure 5 and Figure 7As shown, slider 12 is fixedly connected to both end faces inside the roller body 1. A convex block 16 is fixedly connected inside the slider 12. One end face of the shaft body 2 is fixedly connected to the slider 12, and a convex block 16 is fixedly connected inside the slider 12. By engaging the convex block 16 on the surface of the slider 12 with the chute 11 on the surface of the rotating shaft 3, the connection between the rotating shaft 3 and the slider 12 is made more stable, effectively preventing the problem of loose connection or slippage between the slider 12 and the convex block 16.

[0029] As Figure 3 , Figure 5 and Figure 7 shown, a number of chutes 11 are provided on the surface of the rotating shaft 3. By installing the convex block 16 inside the slider 12 on the surface of the shaft body 2, the convex block 16 can be connected to the internal chute 11. During the rotation of the rotating shaft 3, the shaft body 2 is driven to rotate together through the convex block 16 and the chute 11, so that the rotating shaft 3 and the shaft body 2 achieve synchronous rotation.

[0030] As Figure 3 , Figure 5 and Figure 7 shown, the number of convex blocks 16 is the same as the number of chutes 11. The convex block 16 is slidably connected to the chute 11. The convex block 16 can slide inside the chute 11, which can adjust the length of the rotating shaft 3 outside the roller body 1, and further control the adjustment of the length of the rotating shaft 3, thus achieving the controllability of adjusting the length of the rotating shaft 3.

[0031] Working principle: Place the roller body 1 on a plane. Rotate the iron rod 4 at one end to make the first bevel gear 9 rotate. When the first bevel gear 9 rotates, it makes the second bevel gear 10 rotate. When the second bevel gear 10 rotates, it makes the lead screw 6 rotate synchronously. When the lead screw 6 rotates, it makes the nut 7 move downward. When the nut 7 moves downward, it makes the driving wall 8 rotate slowly and move the rotating shaft 3 slowly outwards from the roller body 1. When the rotating shaft 3 is moved out to the required length, stop rotating the iron rod 4 so that the rotating shaft 3 cannot continue to move outwards from the roller body 1. Rotate the iron rod 4 in the reverse direction to make the iron rod 4 drive the first bevel gear 9 to rotate in the reverse direction. When the first bevel gear 9 rotates in the reverse direction, it drives the second bevel gear 10 to rotate in the reverse direction. When the second bevel gear 10 rotates in the reverse direction, it drives the lead screw 6 to rotate synchronously in the reverse direction. When the lead screw 6 rotates in the reverse direction, it makes the nut 7 move upward. When the nut 7 moves upward, it makes the driving wall 8 rotate slowly and retract the rotating shaft 3 slowly. When the nut 7 reaches the top of the lead screw 6, it is impossible to continue rotating the iron rod 4. At this time, the rotating shaft 3 is retracted. By rotating the iron rods 4 on both sides, the length of the rotating shaft 3 outside the roller body 1 is adjusted. By rotating the iron rod, the lengths of the rotating shafts on both sides of the roller body are adjusted, so that the roller body can be installed on different types of brackets, and then the roller body can be installed on different brackets, making the use scenario of the roller body more extensive.

[0032] The roller body 1 is installed inside the device and is installed in the installation groove inside the device through the rotating shaft 3. When the device drives the rotating shaft 3 to rotate, the rotating shaft 3 drives the slider 12 to rotate synchronously through the chute 11 on its surface. The rotation of the slider 12 drives the shaft body 2 to rotate, and the rotation of the shaft body 2 drives the roller body 1 to rotate. Through the cooperation of the chute 11 and the slider 12, it can effectively solve the problem that the rotating shaft 3 can be removed from the inside of the shaft body 2 without affecting the rotation of the shaft body driven by the rotating shaft 3, so that the rotating shaft 3 and the roller body 1 can rotate synchronously.

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them.
