Description

Technical Field

[0001] The utility model relates to the technical field of anodizing pretreatment, in particular to an anodizing surface pretreatment device. Background Art

[0002] Anodizing is the electrochemical oxidation of metals or alloys. Aluminum and its alloys form an oxide film on aluminum products under the action of an applied current in the corresponding electrolyte and specific process conditions. If no special instructions are given, anodizing usually refers to sulfuric acid anodizing.

[0003] Before anodizing, metals need to be pre-treated with pickling because oil and oxide layers easily adhere to the metal surface. Existing pre-treatment devices usually hang the metal on a rack and place it directly into the pickling tank for pickling. Since there is a certain connection between the metal and the rack, the connection cannot be in contact with the acid solution, resulting in poor surface treatment effect at this location, which is easy to affect the subsequent anodizing quality. Therefore, an anodizing surface pre-treatment device is needed to meet the needs. Utility Model Content

[0004] The purpose of the present invention is to provide an anodized surface pretreatment device to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anodized surface pretreatment device, comprising a base, a plurality of springs provided on the base, a same pickling tank provided on the plurality of springs, an inclined bracket provided on the pickling tank, a motor provided on the inclined bracket, a first helical gear connected to the output end of the motor, a connecting shaft connected to the first helical gear, a second helical gear connected to one end of the connecting shaft, the second helical gear and the first helical gear being symmetrical with each other, a third helical gear and a fourth helical gear being rotatably connected to the inclined bracket respectively, the third helical gear and the first helical gear being meshed with each other, the fourth helical gear and the second helical gear being meshed with each other, the third helical gear and the fourth helical gear being connected to a rotating shaft, both rotating shafts being connected to an eccentric pendulum, and the two eccentric pendulums being arranged relatively symmetrically.

[0006] Preferably, lug plates are provided around the base, and fixing holes are opened on the lug plates.

[0007] Preferably, the base and the pickling tank are hingedly connected through a plurality of hinges and connecting rods.

[0008] Preferably, a sieve plate is provided in the pickling tank, and the sieve plate is arranged in an inclined shape.

[0009] Preferably, a cleaning port is provided on one side of the pickling tank, and the cleaning port is located on the side of the sieve plate that is inclined upward.

[0010] Preferably, the pickling tank is provided with an oblique support rod, which is symmetrical in angle to the oblique support rod and is connected to the oblique support rod.

[0011] Preferably, two first support plates are provided on the oblique bracket, and the two first support plates are respectively arranged on the side where the first helical gear and the second helical gear face away from each other. Two second support plates are provided on the oblique bracket, and are respectively arranged on the side where the third helical gear faces away from the first helical gear, and the side where the fourth helical gear faces away from the second helical gear. The two rotating shafts are respectively rotatably connected in the second support plates.

[0012] The beneficial effects of the utility model are:

[0013] In the utility model, the first bevel gear is driven to rotate by a motor, and the second bevel gear and the first bevel gear are connected via a connecting shaft so as to rotate synchronously in the same direction. Since the first bevel gear and the second bevel gear are symmetrical with each other, the third bevel gear and the fourth bevel gear are rotated synchronously relative to each other. The two eccentric pendulums are connected via a rotating shaft so as to rotate synchronously relative to each other. Since the pickling tank and the base are flexibly connected via a spring, the pickling tank vibrates in a tilted direction with a certain amplitude under the guidance of the tilting force generated when the two eccentric pendulums rotate, thereby causing the internal metal to have a bumpy effect, preventing the problem that one side of the metal is always in contact with the bottom of the tank and cannot come into contact with the acid solution, thereby making the pretreatment of the metal surface pickling more thorough.

[0014] In the utility model, the vibration effect in the inclined direction of the pickling tank is used to produce a horizontal conveying effect on the metal in the pickling tank, thereby facilitating the gathering and removal of the metal after pickling. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] The first bevel gear 6 is driven to rotate by the motor 5, and the second bevel gear 8 and the first bevel gear 6 are connected by the connecting shaft 7 to generate synchronous rotation in the same direction. Since the first bevel gear 6 and the second bevel gear 8 are symmetrical with each other, the third bevel gear 9 and the fourth bevel gear 10 generate synchronous relative rotation. They are connected by the rotating shaft 11 to generate synchronous relative rotation of the two eccentric pendulums 12. Since the pickling tank 3 and the base 1 are flexibly connected by the spring 2, the pickling tank 3 generates a certain amplitude of tilted direction vibration under the guidance of the tilting force generated when the two eccentric pendulums 12 rotate, thereby causing the internal metal to produce a bumpy effect, preventing the problem that one side of the metal is always in contact with the bottom of the tank and cannot contact the acid solution, making the pretreatment of the metal surface pickling more thorough. Through the vibration effect of the tilted direction of the pickling tank 3, the metal is horizontally conveyed in the pickling tank 3, thereby facilitating the aggregation and removal of the metal after pickling.

[0023] Specifically, in this embodiment, ear plates 13 are provided on all four sides of the base 1. Fixing holes 14 are opened on the ear plates 13. Expansion bolts can be used to fix the device on the ground to ensure the stability of the vibration effect.

[0024] Specifically, in this embodiment, the base 1 and the pickling tank 3 are hinged by a plurality of hinges 15 and connecting rods 16, thereby improving the stability of the connection between the base 1 and the pickling tank 3 and further promoting the vibration of the pickling tank 3 in the horizontal tilt direction.

[0025] Specifically, in this embodiment, a sieve plate 17 is provided in the pickling tank 3. The sieve plate 17 is arranged in an inclined shape to provide bottom support for the metal, so that the metal has a gradual upward trend during transportation, which facilitates the removal of the metal.

[0026] Specifically, in this embodiment, a cleaning port 18 is provided on one side of the pickling tank 3. The cleaning port 18 is located on the upwardly inclined side of the sieve plate 17 and is used to clean and discharge impurities after pickling.

[0027] Specifically, in this embodiment, an oblique support rod 19 is provided on the pickling tank 3 . The oblique support rod 19 is symmetrical with the oblique support 4 and is connected to the oblique support 4 to improve the stability of the oblique support 4 .

[0028] Specifically, in this embodiment, two first support plates 20 are provided on the oblique bracket 4, and the two first support plates 20 are respectively arranged on the side where the first helical gear 6 and the second helical gear 8 face away from each other. Two second support plates 21 are provided on the oblique bracket 4, which are respectively arranged on the side where the third helical gear 9 faces away from the first helical gear 6, and on the side where the fourth helical gear 10 faces away from the second helical gear 8.
