Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of aluminum foil processing, in particular to an aluminum foil high-stable Gr content passivation buffer device. Background Art
[0002] Aluminum foil passivation refers to the process of forming a stable oxide film on the surface of aluminum foil through a series of chemical treatment methods to improve the corrosion resistance of aluminum foil. For example, a chromium oxide layer is often passivated on the surface of aluminum foil.
[0003] After the passivation process, the existing aluminum foil needs to be cut again. However, during the cutting process, the friction between the cutting blade and the aluminum foil causes the chromium oxide layer on the aluminum foil to wear, resulting in the peeling and loss of the chromium oxide layer, and the stability of the chromium content cannot be maintained. Therefore, a high-stable Gr content passivation buffer device for aluminum foil is proposed. Utility Model Content
[0004] The utility model aims to solve the problems raised in the background technology and proposes a high-stable Gr content passivation buffer device for aluminum foil.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A high-stable Gr content passivation buffer device for aluminum foil comprises a fixed plate, a conveying roller, a cylinder and a cutting straight blade, wherein the conveying roller is symmetrically rotatably arranged on the side of the fixed plate, the cylinder is fixedly installed on the top of the fixed plate, and the end of the piston rod of the cylinder is fixedly connected to the cutting straight blade; a support seat is fixedly provided on the side of the fixed plate and located between two conveying rollers, a buffer plate is provided above the support seat, and sliding rods slidably connected to the support seat are fixedly provided on both sides of the lower surface of the buffer plate, and the rod walls of the two sliding rods are sleeved with first springs.
[0007] Preferably, anti-fall-off blocks are fixedly provided at the lower ends of the two sliding rods.
[0008] Preferably, a retreat groove is provided on the upper surface of the buffer plate at a position corresponding to the position of the cutting straight blade.
[0009] Preferably, sliding grooves are provided on both sides of the retreat groove, and retreat plates are provided inside the sliding groove for transverse sliding, and the opposite sides of the two retreat plates are connected to the side walls of the sliding groove through a second spring.
[0010] Preferably, an inclined guide groove is provided at the top of the side where the two retreat plates contact each other.
[0011] Preferably, two fixing rings are symmetrically fixed on the top of the fixing plate.
[0012] Compared with the prior art, the utility model provides an aluminum foil high-stable Gr content passivation buffer device, which has the following beneficial effects:
[0013] 1. The aluminum foil high-stable Gr content passivation buffer device has a buffer plate, a slide bar and a first spring arranged below the cutting straight blade. When the cutting straight blade moves downward to cut the aluminum foil, the buffer plate is squeezed. The buffer plate moves downward through the slide bar and squeezes the first spring, so that the buffer plate has an elastic expansion and contraction function, which can reduce the friction and wear between the cutting straight blade and the surface of the aluminum foil, thereby reducing the peeling and loss of the chromium oxide layer and maintaining the stability of the chromium content.
[0014] 2. The aluminum foil high-stable Gr content passivation buffer device has a retreat groove, a retreat plate, a second spring and an inclined guide groove arranged on the buffer plate. When the cutting straight blade moves downward and completes cutting the aluminum foil, the lower end of the cutting straight blade first extends into the interior of the inclined guide groove, so that the two retreat plates move to both sides and squeeze the second spring. At this time, the phenomenon of hard collision of the cutting straight blade can be avoided. When the cutting straight blade moves upward, the second spring applies elastic force to the retreat plate, so that the two retreat plates are relatively close to each other and the retreat groove is blocked, which can ensure that the aluminum foil is supported.
[0015] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. The utility model has an elastic buffer structure, which can reduce the friction and wear between the cutting straight blade and the surface of the aluminum foil, thereby reducing the peeling and loss of the chromium oxide layer and maintaining the stability of the chromium content.

Two fixing rings 14 are symmetrically fixed on the top of the fixed plate 1. Fixing bolts can be inserted into the fixing rings 14 so that the fixed plate 1 can be fixed on the machine body. The conveying roller 2 is symmetrically rotated and arranged on the side of the fixed plate 1. The cylinder 3 is fixedly installed on the top of the fixed plate 1, and the end of the piston rod of the cylinder 3 is fixedly connected with the cutting straight blade 4. When the cylinder 3 is extended, it can drive the cutting straight blade 4 to move downward, so that the cutting straight blade 4 cuts the passivated aluminum foil; a fixed plate 1 is fixedly provided on the side of the fixed plate 1 and located between the two conveying rollers 2. A support seat 5 is provided with a buffer plate 6 above the support seat 5. Slide rods 7 slidably connected to the support seat 5 are fixedly provided on both sides of the lower surface of the buffer plate 6. The rod walls of the two slide rods 7 are sleeved with first springs 8. The lower ends of the two slide rods 7 are fixedly provided with anti-falling blocks 9. The anti-falling blocks 9 can prevent the slide rods 7 from falling off from the support seat 5. When the cutting straight blade 4 moves downward to cut the aluminum foil, the buffer plate 6 is squeezed. The buffer plate 6 will move downward through the slide rod 7 and squeeze the first spring 8, so that the buffer plate 6 has the function of elastic expansion and contraction, which can reduce the friction and wear between the cutting straight blade 4 and the surface of the aluminum foil, thereby reducing the peeling and loss of the chromium oxide layer and maintaining the stability of the chromium content.
[0023] Reference Figure 2-3A retreat groove 10 is provided on the upper surface of the buffer plate 6 and at the position corresponding to the position of the cutting straight blade 4. Sliding grooves are provided on both sides of the retreat groove 10, and a retreat plate 11 is provided inside the sliding groove for transverse sliding. The two retreat plates 11 are connected to the side wall of the sliding groove on the opposite sides through a second spring 12.

When the cutting straight blade 4 moves down and completes the cutting of the aluminum foil, the lower end of the cutting straight blade 4 first extends into the interior of the inclined guide groove 13, so that the two retreat plates 11 move to both sides and squeeze the second spring 12. At this time, the phenomenon of hard collision of the cutting straight blade 4 can be avoided. When the cutting straight blade 4 moves up, the second spring 12 applies elastic force to the retreat plate 11, so that the two retreat plates 11 are relatively close to each other and block the retreat groove 10, which can ensure that the aluminum foil is supported.
[0024] In the utility model, when in use, the passivated aluminum foil is placed on two conveying rollers 2 for transmission. When the aluminum foil needs to be cut, the cylinder 3 is turned on to work.
