Description

Technical Field

[0001] This utility model relates to the field of tensioning device technology, specifically to a cathode roller O-ring tensioning device. Background Technology

[0002] In the copper foil production process, the cathode roller plays a crucial role, and the O-ring, which prevents electrolyte leakage, is indispensable. Its service life has an inseparable impact on the production efficiency and quality of copper foil. After being soaked in electrolyte for a long time, the acid-resistant rubber strip deforms, causing the O-ring to loosen. The tensioning device needs to be manually adjusted to control the tightness. Manual adjustment is inefficient, can easily damage the O-ring, and poses certain risks to personnel safety.

[0003] To address the above situation, an automatic O-ring tensioning device is needed to keep the O-rings taut throughout the entire production process, reduce damage to the O-rings caused by human operation, ensure no electrolyte leakage, reduce the risk of human operation, and shorten operation time.

[0004] Therefore, a cathode roller O-ring tensioning device is provided to solve the above-mentioned technical problems. Summary of the Invention

[0005] The technical problem to be solved by this utility model is that the existing technology requires manual adjustment of the tensioning device to control the tightness, which is inefficient, damages the O-ring, and poses certain risks to personnel safety.

[0006] To achieve the above objectives, the technical solution of this utility model is: a cathode roller O-ring tensioning device, comprising a base and a lead screw, characterized in that: two bearings are fixedly installed on one side of the base, and pulleys are rotatably connected to each of the two bearings; an upper fixing block is provided at the upper end of the base, and a through hole is provided in the middle of the upper fixing block; a lower fixing block is provided at the lower end of the base, and a threaded through hole is provided in the middle of the lower fixing block; the lead screw passes through the through hole and the threaded through hole in sequence; the lower end of the lead screw is threadedly connected to the threaded through hole; a spring is sleeved on the lead screw; and a movable pulley assembly is connected to the upper end of the spring.

[0007] As a preferred embodiment of this utility model, the movable pulley assembly includes a movable block and a second pulley. The movable block is slidably connected to a lead screw, and the lower end of the movable block is connected to the upper end of a spring. A second bearing is fixedly installed on one side of the movable block, and a second pulley is rotatably connected to the second bearing.

[0008] As a preferred embodiment of this utility model, a nut is threaded onto the lead screw, and the spring is disposed on the upper surface of the nut.

[0009] As a preferred embodiment of this utility model, both the second pulley and the two first pulleys are made of nylon.

[0010] As a preferred embodiment of this utility model, the upper end of the lead screw is connected to a rotating handle.

[0011] Compared with related technologies, the cathode roller O-ring tensioning device provided by this utility model has the following advantages: By adjusting the nut to the appropriate height, the O-ring is then placed inside pulley two and the two pulleys one. Rotating the handle causes the lead screw to move upward. Simultaneously, the upward movement of the lead screw drives the spring upward. Since the spring is located on the upper surface of the nut, and the nut is stationary relative to the lead screw, the elastic potential energy of the spring lifts the moving block, causing pulley two to lift as well. This tensions the O-ring, keeping it constantly taut and preventing damage from excessive force during manual operation or loosening due to insufficient force. By providing a constant energy to the O-ring through the spring, the O-ring is prevented from being too tight (causing damage and reduced lifespan) or too loose (causing unnecessary friction with other equipment and further damage and reduced lifespan). This reduces the risk of manual operation and extends the lifespan of the O-ring.

[0012] The pulleys are made of nylon, which has good corrosion resistance during the production process. Nylon causes less damage to the O-ring when it comes into contact with and rubs against it. Attached Figure Description

[0013] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0016] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0017] Example like Figure 1-2 As shown, this utility model discloses a cathode roller O-ring tensioning device, including a base 1 and a lead screw 5. Two bearings are fixedly installed on one side of the base 1, and pulleys 2 are rotatably connected to each bearing. An upper fixing block 3 is provided at the upper end of the base 1, and a through hole is provided in the middle of the upper fixing block 3. A lower fixing block 4 is provided at the lower end of the base 1, and a threaded through hole is provided in the middle of the lower fixing block 4. The lead screw 5 passes through the through hole and the threaded through hole in sequence. A rotating handle 9 is connected to the upper end of the lead screw 5. By rotating the rotating handle 9, the extension length of the lead screw 5 can be extended and shortened. The lower end of the lead screw 5 is threadedly connected to the threaded through hole. A spring 6 is sleeved on the lead screw 5. A movable pulley assembly 7 is connected to the upper end of the spring 6. A nut 8 is threadedly connected to the lead screw 5. The spring 6 is located on the upper surface of the nut 8. That is to say, when the rotating handle 9 is rotated, the lead screw 5 adjusts its extension length, and the nut 8 on it will also move with the lead screw 5, thereby driving the spring 6 to move.

[0018] Furthermore, the movable pulley assembly 7 includes a movable block 71 and a second pulley 72. The movable block 71 is slidably connected to the lead screw 5, and the lower end of the movable block 71 is connected to the upper end of the spring 6. A second bearing is fixedly installed on one side of the movable block 71, and a second pulley 72 is rotatably connected to the second bearing. The second pulley 72 and the two first pulleys 2 are all made of nylon. The O-ring is tensioned by the movement of the second pulley 72 in conjunction with the two first pulleys 2.

[0019] In use, this technical solution involves first adjusting the nut 8 to the appropriate height, then placing the O-ring inside pulley 72 and the two pulleys 2. Rotating the handle 9 causes the lead screw 5 to move upwards. Simultaneously, the lead screw 5 moves the spring 6 upwards. Since the spring 6 is located on the upper surface of the nut 8, and the nut 8 is stationary relative to the lead screw 5, the elastic potential energy of the spring 6 lifts the moving block 71, causing pulley 72 to lift as well. This tensions the O-ring, ensuring it remains taut and preventing damage from excessive force or loosening from insufficient force during manual operation. By providing a constant energy to the O-ring through the spring 6, the O-ring is prevented from becoming too tight (damaging it and reducing its lifespan) or too loose (causing unnecessary friction with other equipment and reducing its lifespan). This reduces the risk of manual operation and extends the lifespan of the O-ring.

[0020] The pulleys are made of nylon, which has good corrosion resistance during the production process. Nylon causes less damage to the O-ring when it comes into contact with and rubs against it.

[0021] The thread connecting the lower fixed block 4 and the lead screw 5 is M16, the spring is 2.0*21*150mm, and bearings one and two are 6004CE type bearings for transmission.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
