Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] This utility model provides a PU synthetic leather coating device, such as... Figure 1-7 As shown, the system includes a lifting plate 1, a base plate 2 fixedly mounted below the lifting plate 1, and an extension plate 4 mounted at the bottom end of the base plate 2. Synthetic leather conveying assemblies are mounted at both the front and rear ends of the extension plate 4. A vertical plate 101 is mounted at the top of the lifting plate 1, and a torsion bearing 12 is fixedly mounted at the top of the vertical plate 101. A crankshaft 1201 is rotatably inserted through the middle of the torsion bearing 12. Guide rods 11 are mounted at both ends of the torsion bearing 12, and the top ends of the guide rods 11 are rotatably connected to the ends of the crankshaft 1201. A guide assembly is provided at the bottom end of rod 11; the guide assembly includes a guide rod 301, and a ball joint assembly is provided between the bottom end of guide rod 301 and guide rod 11. A guide sleeve 302 matching guide rod 301 is fixedly provided on the side wall of the lifting plate 1. A coating roller 3 is provided at the bottom end of guide rod 301, and a paint chamber matching coating roller 3 is provided at the top end of base plate 2. The synthetic leather conveying assembly conveys synthetic leather through the middle of coating roller 3, and the crankshaft 1201 is connected to the drive assembly.

[0022] In this embodiment, the crankshaft 1201 drives the guide rod 11 to move up and down once for each rotation. During this up-and-down movement, the guide rod 301 also slides in the guide sleeve 302. The brush roller 3 at the bottom of the guide rod 301 moves up and down. Thus, for each cycle of the guide rod 301 moving up and down, the brush roller 3 at the bottom of the guide rod 301 will insert into the paint chamber once. This ensures that the outer surface of the brush roller 3 has sufficient paint. Compared with the existing painting equipment, the painting part of this device is in long-term contact with synthetic leather, which can easily lead to wear of the painting parts. Damage to the painting parts will affect subsequent painting operations. The brush roller 3 of this invention moves up and down, and the brush roller 3 will not have a certain part in contact with synthetic leather for a long time. This avoids wear of a certain part of the brush and improves the service life of the device parts.

[0023] In a further embodiment of this utility model, such as Figure 1-4 As shown, the synthetic leather conveying assembly includes material changing bearings 501 at the front and rear ends of the extension plate 4. The outer ring of the material changing bearing 501 is fixedly connected to the extension plate 4. A vertical rod 5 is fixedly installed in the inner ring of the material changing bearing 501. A synthetic leather roller 6 is installed at the top of the vertical rod 5. Synthetic leather 601 is pulled out from the outer side of the rear synthetic leather roller 6 and connected to the outer side wall of the front synthetic leather roller 6. The front vertical rod 5 is connected to the output end of the stepper motor 7. The stepper motor 7 is fixed to the bottom end of the extension plate 4.

[0024] In this embodiment, the synthetic leather 601 to be processed is pulled out and passed between two coating rollers 3. When the stepper motor 7 drives the synthetic leather roller 6, the synthetic leather 601 between the synthetic leather rollers 6 will pass through the coating rollers 3 at a uniform speed. In the process of the synthetic leather 601 being rolled from one synthetic leather roller 6 to another synthetic leather roller 6, the coating is evenly applied, thus achieving the effect of automatic processing.

[0025] In a further embodiment of this utility model, such as Figure 1-4 As shown, the rear-end material changing bearing 501 is filled with damping oil, the front-end material changing bearing 501 is filled with lubricating oil, the top of the upright 5 is provided with a block, the bottom of the synthetic leather roller 6 is provided with a matching locking groove, the block is made of steel, and a magnet is provided inside the locking groove.

[0026] In this embodiment, the synthetic leather roller 6 for feeding is inserted into the material changing bearing 501 filled with damping oil. The synthetic leather roller 6 will not spring back during the discharge process. Compared with the existing spring synthetic leather conveying device, spring synthetic leather has strong elasticity. The elasticity of the synthetic leather 601 itself will also affect the synthetic leather roller 6 itself. Filling the material changing bearing 501 with damping oil will prevent the synthetic leather roller 6 from shaking or even reversing, thereby maintaining the stability of the synthetic leather 601 during the conveying process.

[0027] In a further embodiment of this utility model, such as Figure 5-7 As shown, the ball joint assembly includes a disassembly plate at the bottom of the guide rod 11, a ball shell 1101 is provided on the side wall of the disassembly plate, and a steel ball matching the ball shell 1101 is provided at the top of the guide rod 301.

[0028] In this embodiment, the crankshaft 1201 drives the guide rod 11 to move up and down once for each revolution. When the guide rod 301 moves up and down, it rotates inside the ball housing 1101. The staff will add oil to the ball housing 1101 regularly according to the usage of the equipment.

[0029] In a further embodiment of this utility model, such as Figure 5-7 As shown, the spiral density of the guide rod 301 is one turn per centimeter.

[0030] In a further embodiment of this utility model, such as Figure 1-3 As shown, the outline of the coating chamber matches the outline of the coating roller 3, and the inner wall of the coating chamber is provided with an annular array of discharge ports, which are connected to the feeding assembly.

[0031] In this embodiment, when the brush roller 3 is fully inserted into the paint chamber, a certain amount of paint is discharged from the outlet. When the brush roller 3 is not inside the paint chamber, the outlet stops discharging paint. Compared with the existing paint conveying device, the paint conveyed in the past is prone to waste, and a lot of paint may even splash out, which will also pollute the processing workshop and the paint is difficult to clean.

[0032] In a further embodiment of this utility model, such as Figure 1-3 As shown, the feeding assembly includes a pump body 901 and a storage tank 10. The pump body 901 and the storage tank 10 are fixed on the side wall of the base plate 2. The input pipe of the pump body 901 is connected to the storage tank 10. The output end of the pump body 901 is provided with a surrounding steel pipe 9. The surrounding steel pipe 9 surrounds to the other side of the base plate 2. Two branch joints are connected to the surrounding steel pipe 9. Solenoid valves are provided on the branch joints. The branch joints are respectively connected to the discharge port inside the paint chamber.

[0033] In this embodiment, the pump body 901 draws paint from the inside of the storage tank 10, and the pump body 901 pushes the paint into the paint chamber through the surrounding steel pipe 9. The solenoid valve controls the rhythm of the discharge from the outlet inside each paint chamber.

[0034] In a further embodiment of this utility model, such as Figure 1-3 As shown, the drive assembly includes a reduction wheel 1202 on the outer side of the crankshaft 1201, a servo motor 8 on the side wall of the upright plate 101, and the output end of the servo motor 8 drives the wheel 801 in this way. The drive wheel 801 and the reduction wheel 1202 are connected by a reduction belt 13.

[0035] In this embodiment, the servo motor 8 drives the reduction wheel 1202 to rotate through the drive wheel 801 and the reduction belt 13. The crankshaft 1201 rotates together with the reduction wheel 1202, and the servo motor indirectly transmits power to the crankshaft 1201.

[0036] In a further embodiment of this utility model, such as Figure 6-7 As shown, the diameter ratio of the drive wheel 801 and the reduction wheel 1202 is 1:2, and the reduction wheel 1202 and the crankshaft 1201 are detachable.

[0037] In this embodiment, when it is necessary to adjust the torque of the reduction wheel 1202 and the crankshaft 1201, the reduction wheel 1202 is replaced with a different diameter model. The smaller the diameter ratio of the drive wheel 801 and the reduction wheel 1202, the greater the torque of the reduction wheel 1202 and the crankshaft 1201 will be. The operator will make adjustments according to the actual processing situation.

[0038] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
