Description

Technical Field

[0001] This utility model relates to dyeing equipment, and in particular, to a steel coil dyeing sample making machine. Background Technology

[0002] Color-coated steel coils are steel coils with a colored coating on their surface. They are widely used in construction, home appliances and other fields. Color-coated steel coils are made by coating ordinary steel coils with pigments.

[0003] For example, Chinese Patent No. CN203578109U discloses a double-sided, two-color painting device for steel tape measure strips, including guide wheels and an a-painting device on the left side and a b-painting device on the right side of the steel tape measure strip. Both the a-painting device and the b-painting device include a paint cylinder, a paint-applying roller, a paint-scraping roller, and a paint-coating roller. After the paint-applying roller rotates in the paint cylinder to obtain paint, it rotates and contacts the paint-coating roller and transfers the paint to the paint-coating roller. The paint-coating roller, in the order of its movement direction, first rotates and contacts the paint-scraping roller and then moves relative to the steel tape measure strip to realize the double-sided, two-color painting operation of the steel tape measure strip.

[0004] In the actual process of applying pigments to some small-batch custom color-coated steel coils, color differences are prone to occur. The thickness of the pigment application will have a certain impact on the color presentation. Therefore, a device for making color-coated steel coil samples is needed. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a steel coil dyeing and sampling machine, which has the function of producing multiple color-coated steel coil samples at one time.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a steel coil dyeing and sampling machine, including a frame, a power source, a material conveying component, and a coloring roller. The power source drives the material conveying component to convey materials and simultaneously drives the coloring roller to rotate. The material conveying component is set on the frame and transports the steel coil to the bottom of the coloring roller. The coloring roller is also set on the frame. A pigment cavity is also provided between the material conveying component and the coloring roller. Multiple coloring areas are opened on the coloring roller, and the thickness of the pigment applied between the coloring areas is different. A cleaning component for cleaning the coloring roller is also provided on the frame.

[0007] Preferably, the surface of the coating roller is provided with multiple storage holes, and the diameter and density of the storage holes in different coating areas are different. When the storage holes rotate to the pigment chamber, they store pigment, and when they move to the steel coil, they apply the pigment to the surface of the steel coil.

[0008] Preferably, the material conveying assembly includes a material conveying roller and a material conveying belt. The material conveying roller is in contact with the coloring roller to form a pigment cavity. The material conveying belt is disposed at the bottom of the material conveying roller and the coloring roller and cooperates with the material conveying roller to realize the movement of the steel coil.

[0009] Preferably, the power source includes a geared motor fixedly mounted on the frame, the output end of the geared motor being fixed to the conveying roller, and both the conveying roller and the coating roller being provided with drive gears, the two drive gears meshing with each other, and the conveying roller rotating to drive the coating roller to rotate.

[0010] Preferably, the frame is also provided with a receiving groove, which is located at the bottom of both sides of the conveying roller and the coloring roller. The receiving groove is used to receive the pigment flowing out from the side end of the pigment chamber.

[0011] Preferably, the frame is further provided with a sliding rod, on which a pair of side baffles are slidably mounted. The side baffles, together with the conveying roller and the coloring roller, form a pigment cavity. Fixing bolts are also provided on the side baffles.

[0012] Preferably, the cleaning assembly includes a drive screw, a limiting rod, and a negative pressure head. The negative pressure head is threadedly engaged with the drive screw, the limiting rod is slidably engaged with the negative pressure head, and a negative pressure tube is connected to the tail of the negative pressure head. The negative pressure head is used to clean residual pigment on the coating roller.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. Multiple coloring zones on the coloring roller enable multi-thickness coloring of the steel coil surface, improving the efficiency and flexibility of dyeing and sampling. The varying pigment thickness between coloring zones caters to different customer needs for steel coil dyeing effects, allowing for switching between various dyeing schemes without changing the coloring roller. 2. By setting up a receiving trough, excess pigment is collected. By setting up a side baffle, the loss of pigment is reduced. When it is necessary to clean up the pigment, the side baffle on one side can be moved out to allow the pigment to flow into the receiving trough. 3. By setting a negative pressure head and generating negative pressure suction, residual pigment in contact with the negative pressure head is sucked away, keeping the coating roller clean.

[0016] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so that the technical solution of this utility model can be more easily understood and mastered.

[0017] A steel coil dyeing and sampling machine includes a frame 1, a power source 2, a material conveying component 3, and a coloring roller 4. The frame 1 includes a pair of side mounting plates 5. The power source 2 drives the material conveying component 3 to convey materials and simultaneously drives the coloring roller 4 to rotate. The material conveying component 3 is located between the two side mounting plates 5 and transports the steel coil to the bottom of the coloring roller 4. The coloring roller 4 is also located between the two side mounting plates 5. A pigment cavity 6 is also provided between the material conveying component 3 and the coloring roller 4. The coloring roller 4 has multiple coloring areas 7 with different pigment thicknesses applied between the coloring areas 7. When the steel coil passes through the coloring roller 4, different coloring areas 7 will produce different coloring effects, which can be easily compared. The frame 1 is also provided with a cleaning component 8 for cleaning the coloring roller 4.

[0018] The surface of the coating roller 4 has multiple storage holes 9. The storage holes 9 in different coating zones 7 have different diameters and densities. When the storage holes 9 rotate to the pigment chamber 6, they store pigment and when they move to the steel coil, they apply the pigment to the surface of the steel coil, thereby achieving coating effects of different thicknesses.

[0019] The material conveying assembly 3 includes a material conveying roller 10 and a material conveying belt 11. The material conveying roller 10 is in contact with the coloring roller 4 and forms a pigment cavity 6. The material conveying belt 11 is located at the bottom of the material conveying roller 10 and the coloring roller 4 and works with the material conveying roller 10 to realize the movement of the steel coil.

[0020] The power source 2 includes a geared motor fixedly mounted on the frame 1. The output end of the geared motor is fixed to the conveying roller 10. Both the conveying roller 10 and the coloring roller 4 are equipped with drive gears 12. The two drive gears 12 mesh with each other. When the conveying roller 10 rotates, it drives the coloring roller 4 to rotate, thereby achieving synchronous operation and ensuring that the steel coil is colored during the conveying process.

[0021] The frame 1 is also provided with a receiving groove 13, which is located at the bottom of both sides of the conveying roller 10 and the coloring roller 4. The receiving groove 13 is used to receive the pigment flowing out from the side of the pigment cavity 6, preventing the pigment from dripping randomly and causing waste and pollution. The frame 1 is also provided with a sliding rod 14, on which a pair of side baffles 15 are slidably mounted. The side baffles 15, together with the conveying roller 10 and the coloring roller 4, form the pigment cavity 6. The side baffles 15 are also provided with fixing bolts 16, which are used to fix the side baffles 15 to the sliding rod 14 to prevent them from sliding randomly.

[0022] The cleaning assembly 8 includes a drive screw 17, a limiting rod 18, and a negative pressure head 19. The negative pressure head 19 is threadedly engaged with the drive screw 17, and the limiting rod 18 is slidably engaged with the negative pressure head 19. A negative pressure pipe 20 is connected to the tail of the negative pressure head 19, and the negative pressure pipe 20 is connected to the pump body. It cleans residual pigment on the coating roller 4. The negative pressure head 19 moves and cleans the surface of the coating roller 4 through the rotation of the drive screw 17. During the cleaning process, the negative pressure head 19 is in close contact with the surface of the coating roller 4, adsorbing residual pigment and impurities through negative pressure. The drive screw 17 of the cleaning assembly 8 is linked to the output end of the geared motor through a transmission mechanism.

[0023] The working process of the sample making machine is as follows: The geared motor is started, and power is transmitted to the conveying roller 10 and the coloring roller 4 through the drive gear 12. The conveying roller 10 drives the steel coil forward. When the steel coil passes the bottom of the coloring roller 4, the storage holes 9 of different coloring areas 7 on the surface of the coloring roller 4 release pigment, forming coloring effects of different thicknesses. During the coloring process, excess pigment flows into the receiving trough 13 for collection, avoiding pollution of the equipment and the surrounding environment. After coloring is completed, the cleaning component 8 is activated, and the drive screw 17 drives the negative pressure head 19 to move along the surface of the coloring roller 4. The negative pressure head 19 adsorbs residual pigment and impurities on the coloring roller 4 through the negative pressure pipe 20, thereby keeping the surface of the coloring roller 4 clean and ensuring stable and reliable subsequent sample making results.

[0024] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
