Description

Technical Field

[0001] This invention relates to the field of electroplated aluminum production, and more particularly to a process for producing wear-resistant electroplated aluminum. Background Technology

[0002] Electroplated aluminum foil is a hot stamping material made by coating and vacuum evaporation onto a thin film substrate to add a layer of metal foil. It is widely used for hot stamping patterns on product surfaces. Electroplated aluminum foil consists of a base film layer, a release layer, a dyeing layer, an aluminum plating layer, and an adhesive layer. The dyeing layer is coated on the surface of the aluminum plating layer to give the dyeing layer a metallic luster of the corresponding color.

[0003] Traditional electroplated aluminum is hot-stamped onto the product surface through an adhesive layer, with the dyeing layer on the outermost layer. Although the pattern has a rich metallic luster, the dyeing layer is easily damaged by wear, resulting in pattern breakage and poor wear resistance. Summary of the Invention

[0004] The purpose of this invention is to solve the following problems existing in the prior art: Traditional electroplated aluminum is hot-stamped onto the product surface through an adhesive layer, with the dyeing layer on the outermost layer. Although the pattern has a rich metallic luster, the dyeing layer is easily damaged by wear, resulting in pattern breakage and poor wear resistance.

[0005] To address the problems existing in the prior art, the present invention provides a wear-resistant electroplated aluminum production equipment, including a material conveyor belt equipped with a motor, a coating roller disposed above the material conveyor belt, the motor driving the material conveyor belt to rotate in the opposite direction to the coating roller for coating a dyeing layer on the electroplated aluminum, a covering shell above the material conveyor belt, a core cylinder adapted to rotate on the inner wall of the covering shell, the surface of the core cylinder having an axially extending material accumulation gap, a feeding device above the covering shell for feeding material into the material accumulation gap, the motor drivingly connected to the core cylinder for driving the material accumulation gap on the surface of the core cylinder to rotate downwards and feed material onto the surface of the electroplated aluminum.

[0006] Preferably, a material carrier plate is elastically rotated on the surface of the core cylinder by a torsion spring. The free end of the material carrier plate is connected to the core cylinder by a rubber band. The material carrier plate rotates under the elastic force of the torsion spring, causing the material carrier plate and the rubber band to be concave to form a material accumulation gap. The core cylinder has a top block inside, which presses the lower material carrier plate protruding from the surface of the core cylinder.

[0007] Preferably, the bottom of the covering shell has a discharge outlet, and an air duct is provided on the side of the outlet near the coating roller. The port of the air duct points to the protruding material carrier plate. The air duct is connected to a fan assembly, and the shaft end of the fan assembly is drivenly connected to the motor.

[0008] Preferably, the side of the cannula closest to the coating roller is inclined, and a leveling plate extends downward from the inclined side of the cannula, with the leveling plate parallel to the conveyor belt.

[0009] Preferably, the material leveling plate includes a plate body, the upper surface of which is evenly distributed with a plurality of comb channels, and the comb channels are evenly arranged with a plurality of material holes penetrating the bottom surface of the plate body.

[0010] Preferably, a pressure roller rotates at the bottom of the covering shell, and the pressure roller is located at the end of the uniform plate away from the air duct.

[0011] Preferably, the outer surface of the carrier plate is provided with a heating plate.

[0012] Preferably, the feeding device includes a material box, which is placed above the covering shell. An auger rotates inside the material box. The bottom of the material box is a semi-circular shape that fits the auger. The auger is connected to a motor drive. The bottom of the material box passes through the top of the covering shell. A screen plate is provided at the part where the bottom of the material box passes through the covering shell. A material bin is connected to the top of one end of the material box, and a discharge pipe is connected to the bottom of the other end of the material box.

[0013] A production process based on the aforementioned wear-resistant electroplated aluminum production equipment includes the following specific steps:

[0014] A. The guide conveyor belt and coating roller are rotated in opposite directions by the motor, and the electroplated aluminum is coated with a dyeing layer between the guide conveyor belt and the coating roller.

[0015] B. The feeding device is used to feed wear-resistant granules into the rubber belt. The motor drives the core cylinder to rotate, so that the rubber belt rotates to the lower part and sprinkles the wear-resistant granules on the surface of the dyeing layer.

[0016] C. The dyed layer with abrasion-resistant granules is dried to form an abrasion-resistant layer.

[0017] Compared with related technologies, the wear-resistant electroplated aluminum production process provided by this invention has the following beneficial effects:

[0018] 1. This invention coordinates the operation of the core cylinder, the guide conveyor belt, and the coating roller. The rubber belt on the surface of the core cylinder is sequentially filled with wear-resistant particles, which are then sprinkled onto the dyeing layer at the bottom, forming a continuous and uniform discharge. The wear-resistant particles are evenly sprinkled onto the surface of the dyeing layer by air blowing and the uniform plate. The dyeing layer and the wear-resistant particles combine to form a wear-resistant layer, effectively improving the wear resistance of the electroplated aluminum.

[0019] 2. The material accumulation gap of the present invention is formed by a material carrier plate and a rubber belt. When discharging material in the material accumulation gap, the material carrier plate and rubber belt are protruded from the core cylinder surface by the top block, which helps to discharge all the material, promotes uniform feeding, and makes the quality of the formed wear-resistant layer uniform.

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0029] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0030] Example 1

[0031] like Figure 1 , Figure 2 As shown, a wear-resistant electroplated aluminum production equipment includes a material conveyor belt 1, which is placed horizontally. A coating roller 2 is rotatably installed at one end of the upper surface of the material conveyor belt 1. A motor 3 is connected to one shaft end of the material conveyor belt 1. One shaft end of the material conveyor belt 1 is connected to the shaft end of the coating roller 2 through gear meshing, so that the material conveyor belt 1 and the coating roller 2 rotate synchronously in opposite directions, and the rotational speed of the coating roller 2 is greater than the rotational speed of the material conveyor belt 1.

[0032] The base film of the release layer is passed between the guide conveyor belt 1 and the coating roller 2, and the dyeing material is placed on the surface of the release layer. The dyeing material is squeezed on the surface of the release layer by the guide conveyor belt 1 and the coating roller 2 to form a dyeing layer. At this time, the dyeing layer is in a soft state and the thickness is maintained at 1.5-2 micrometers.

[0033] like Figure 3 , Figure 5 As shown, a coating shell 5 is fixed above the material conveyor belt 1 and behind the coating roller 2. The coating shell 5 is cylindrical and has a discharge port at the bottom. The core cylinder 6 is rotatably installed inside the coating shell 5, and the outer wall of the core cylinder 6 is rotatably adapted to the inner wall of the coating shell 5. Both ends of the core cylinder 6 rotatably pass through the coating shell 5 and are connected to one shaft end of the material conveyor belt 1 through belt drive. Multiple axially extending material accumulation gaps 61 are evenly arranged on the surface of the core cylinder 6.

[0034] The feeding device 4 includes a material box 41, which is fixed to the top of the covering shell 5 and the bottom of the material box 41 penetrates the inside of the covering shell 5. A sieve plate 43 is provided in the penetration part. The bottom of the material box 41 is semi-circular. An auger 42 is rotatably installed inside the material box 41. The auger 42 fits snugly with the semi-circular bottom of the material box 41. One end of the auger 42 rotates out of the material box 41. The auger 42 is connected to the coating roller 2 through a belt drive. A material box 44 is vertically connected to the top of one end of the material box 41. A discharge pipe 45 is connected to the bottom of the other end of the material box 41.

[0035] Wear-resistant granules are placed in the hopper 44. The wear-resistant granules can be ceramic powder or resin powder, and the particle size is maintained at 1-1.2 micrometers. The wear-resistant granules in the hopper 44 fall into the box 41. The auger 42 is synchronously driven to rotate by the motor 3, pushing the wear-resistant granules in the box 41 from one end to the other. During the pushing process, the wear-resistant granules are screened by the sieve plate 43. Wear-resistant granules of qualified size fall into the top of the shell 5. At this time, the core cylinder 6 rotates, so that the material accumulation gap 61 on its surface is fed in sequence. When the material accumulation gap 61 carrying the wear-resistant granules moves to the outlet, the wear-resistant granules are sprinkled on the surface of the dyeing layer. The pressure roller 10 is rotated and installed behind the bottom of the shell 5. The pressure roller 10 directly contacts the surface of the dyeing layer and presses the wear-resistant granules into the dyeing layer. After pressing, the thickness of the dyeing layer is maintained at 1-1.5 micrometers.

[0036] The wear-resistant particles in the material box 41 are pushed and moved by the auger 42 and screened by the screen plate 43. The wear-resistant particles that cannot be screened are not up to standard and are pushed to the discharge pipe 45 for discharge.

[0037] Example 2

[0038] like Figure 3 , Figure 4 As shown, the material accumulation gap 61 is composed of a material carrier plate 7 and a rubber band 71. Multiple grooves are opened on the surface of the core cylinder 6. The axial length of the groove is adapted to the material carrier plate 7. One side of the material carrier plate 7 is elastically rotated in the groove by a torsion spring. The other side of the material carrier plate 7 is connected to the edge of the groove by a rubber band 71. Under normal conditions, the material carrier plate 7 and the rubber band 71 are recessed by the action of the torsion spring to form the material accumulation gap 61.

[0039] A top block 8 is set inside the core cylinder 6. The end of the top block 8 extends out of the core cylinder 6 and is fixed to the covering shell 5. The top block 8 forms a convex shape vertically downward. The material accumulation gap 61 at the top receives the material. When the material accumulation gap 61 carrying wear-resistant particles moves to the bottom, the top block 8 squeezes the material carrier plate 7 to convex out, so that the material carrier plate 7 and the rubber belt 71 protrude out of the surface of the core cylinder 6, which facilitates the complete discharge of wear-resistant particles and avoids the accumulation of material, which causes uneven distribution of wear-resistant particles on the surface of the dyeing layer.

[0040] like Figure 3 As shown, an air duct 51 is opened on the side of the vent near the coating roller 2. The port of the air duct 51 points to the protruding material carrier plate 7. The fan assembly 11 is installed outside the cover shell 5. The shaft end of the fan assembly 11 is connected to the motor 3. The exhaust end of the fan assembly 11 is connected to the air duct 51.

[0041] During the spreading process, the blower assembly 11 is driven to generate airflow, which is introduced into the air duct 51 and then blown out from the bottom of the air duct 51. The airflow is sprayed onto the protruding material carrier plate 7 to disperse the wear-resistant particles and make the wear-resistant particles evenly distributed.

[0042] like Figure 6 , Figure 7 As shown, the side of the sprue closest to the coating roller 2 is inclined, and the inclined side of the sprue extends downward to connect to the leveling plate 9. The leveling plate 9 is parallel to the material conveyor belt 1. The leveling plate 9 includes a plate body 91. Several comb channels 92 are evenly distributed on the upper surface of the plate body 91. Several material holes 93 that penetrate the bottom surface of the plate body 91 are evenly arranged in the comb channels 92.

[0043] The wear-resistant particles blown by the wind are evenly scattered on the surface of the uniform plate 9. At the same time, part of the airflow is conducted along the upper surface of the uniform plate 9. Under the combing of the comb channel 92, the airflow with wear-resistant particles is conducted in a straight and uniform manner. The wear-resistant particles are evenly distributed on the surface of the dyeing layer through the material hole 93.

[0044] The outer surface of the material carrier plate 7 is provided with an electric heating plate 72. The electric heating plate 72 heats the wear-resistant particles in the material accumulation gap 61, so that the wear-resistant particles falling on the surface of the dyeing layer are at a high temperature, which makes it easier for the pressure roller 10 to press the wear-resistant particles into the dyeing layer.

[0045] Example 3

[0046] A production process based on the aforementioned wear-resistant electroplated aluminum production equipment includes the following specific steps:

[0047] A. The guide conveyor belt 1 and coating roller 2 are driven to rotate in the opposite direction by motor 3, and the electroplated aluminum is coated with a dyeing layer between the guide conveyor belt 1 and coating roller 2.

[0048] B. The feeding device 4 is used to feed wear-resistant granules into the rubber belt 71. The motor 3 drives the core cylinder 6 to rotate, so that the rubber belt 71 rotates to the lower part and sprinkles the wear-resistant granules on the surface of the dyeing layer.

[0049] C. The dyed layer with abrasion-resistant granules is dried to form an abrasion-resistant layer.
