Description

Technical Field

[0001] The invention belongs to the technical field of chain painting equipment, and specifically relates to a metal chain surface painting device and a painting process. Background Art

[0002] Chains are generally metal links or rings, and are mostly used for mechanical transmission, traction, or chain-shaped objects used to block traffic and isolate and protect. There are many types of chains, but most chains are composed of chain plates, chain pins, bushings and other components. In the processing steps of metal chains, painting is one of the important processes. Painting on the surface of metal chains can improve its corrosion resistance and increase its service life. When painting chains that block traffic and isolate and protect, the surface of the chain needs to be evenly and comprehensively painted.

[0003] In the prior art, when spraying a chain, it is necessary to first hang the two ends of the chain on hooks, tighten the chain by adjusting the distance between the two hooks, then drive the chain to rotate by a motor, and finally use a spray gun to spray paint on the chain, thereby improving the chain spraying efficiency, such as the Chinese patent with announcement number CN220277334U. However, the above scheme has defects, and the defects are as follows: when the chain is tightened, the chain links are tight, and when the motor drives the chain to rotate, the chain links are always in a tight state. At this time, it is difficult to spray the paint on the connection between the chain links, resulting in incomplete spraying; if the chain is not tightened, when the motor drives the chain to rotate, wear will occur between the chain links, resulting in the paint sprayed on the chain being worn, resulting in uneven paint. Summary of the invention

[0004] The purpose of the present invention is to provide a metal chain surface painting device and a painting process to solve the technical problems in the prior art in view of the deficiencies in the prior art.

[0005] The objective of the present invention can be achieved through the following technical scheme: a metal chain surface spraying device, which comprises a box body, fixed components are installed on the two side walls of the box body, the fixed components are used to hang the chain body, a transmission component is installed on the box body, the transmission component comprises a sliding box and a transmission plate, the sliding box and the transmission plate are slidably matched, a spraying component is installed on the transmission plate, the spraying component comprises a mounting plate, a coating roller component is rotatably installed on the mounting plate, the coating roller component is located at the bottom of the spraying component, one end of the chain body is hung on the fixed component on one side of the box body, and the other end of the chain body is hung on the fixed component on the other side of the box body after being wrapped around the coating roller component.

[0006] As a further optimization or improvement of the present solution, the spraying assembly further comprises a liquid storage tank and a main pipe, the liquid storage tank is connected to the main pipe via a branch pipe, and the liquid storage tank is connected to the coating roller assembly via a connecting pipe.

[0007] As a further optimization or improvement of the present solution, the coating roller assembly includes a liquid filling tube, a liquid outlet sleeve and a liquid absorbent cotton sleeve. A connecting pipe mouth is installed on the side wall of the liquid filling tube, the connecting pipe mouth is connected to the connecting pipe and is rotatably connected to the mounting plate. A rotating block is provided on the liquid filling tube, a flow channel is provided on the rotating block, and the flow channel is connected to the liquid filling tube. A rotating groove is provided on the liquid outlet sleeve, and two liquid outlet holes are provided on the rotating groove. The two liquid outlet holes are separated by a flow blocking plate. The two side walls of the rotating groove are respectively connected to the rotating block by two springs, and the liquid absorbent cotton sleeve is adhered to the outer wall of the liquid outlet sleeve.

[0008] As a further optimization or improvement of the present solution, the fixing assembly includes a hook 1 and a hook 2, which are respectively arranged on the two side walls of the box body, and a threaded rod is provided on both the hook 1 and the hook 2, which are threadedly connected to the box body, and a rotating block is installed on the threaded rod.

[0009] As a further optimization or improvement of the present solution, the first hook and the second hook are of the same height, and there is a gap between the first hook and the second hook.

[0010] As a further optimization or improvement of the present solution, an electric motor is installed on the sliding box, and the electric motor is connected to the transmission plate through a screw rod.

[0011] A metal chain surface painting process, the process is applied to the metal chain surface painting device as described above, the method comprises the following steps:

[0012] Step S1: hang one end of the chain body on the first hook, wrap the other end of the chain body around the coating roller assembly, and then hang it on the second hook;

[0013] Step S2: starting the spraying assembly and the motor, the motor drives the transmission plate to slide along the sliding box, and the transmission plate drives the spraying assembly and the coating roller assembly to move synchronously;

[0014] Step S3: When the coating roller assembly moves, the chain body will rotate along the surface of the coating roller assembly as the coating roller assembly moves. When the chain body is not in contact with the coating roller assembly, the chain links are in a tensioned state, and the connecting parts between the chain links remain unchanged. When the chain body is in contact with the coating roller assembly, the chain links rotate, and the connecting parts between the chain links change dynamically. At this time, the spraying assembly can spray the connecting parts between the chain links.

[0015] As a further solution of the present invention: the step S3 specifically comprises the following steps:

[0016] Step S31: When the coating roller assembly moves, the chain body drives the liquid outlet sleeve to rotate first. Since the rotation damping of the liquid filling tube is relatively large, the liquid outlet sleeve rotates while the liquid filling tube is relatively fixed. At this time, the spring on the liquid outlet sleeve is compressed and presses the rotating block. When the spring is compressed to the limit, the liquid outlet sleeve rotates and drives the liquid filling tube to rotate synchronously. At this time, the flow channel is aligned with the liquid outlet hole;

[0017] Step S32: the paint liquid in the liquid filling tube flows out through the flow channel and the liquid outlet hole and infiltrates the liquid absorbing cotton sleeve. When the front side of the chain body contacts the liquid absorbing cotton sleeve, the liquid absorbing cotton sleeve infiltrates the paint on the front side of the chain body.

[0018] Step S33: When the roller assembly stops moving, the spring rebounds and drives the flow channel to separate from the liquid outlet. At this time, the flow channel is blocked by the flow blocking plate, and the paint in the liquid filling tube stops being transported to the liquid absorbing cotton sleeve.

[0019] Beneficial effects of the present invention:

[0020] (1) When the coating roller assembly of the present invention moves, the chain body will rotate along the surface of the coating roller assembly as the coating roller assembly moves. When the chain body is not in contact with the coating roller assembly, the chain links are in a tensioned state, and the connection between the chain links remains unchanged. When the chain body is in contact with the coating roller assembly, the chain links rotate, and the connection between the chain links changes dynamically, thereby ensuring that the spraying assembly can spray the connection between the chain links, solving the problem that it is difficult to spray the connection between the chain links in the prior art. Since the spraying assembly sprays paint vertically downward, when the chain link passes through the horizontal part of the coating roller assembly, the chain link is perpendicular to the side wall of the coating roller assembly. At this time, the spraying assembly can specifically spray the inside of the chain, improving the uniformity of the paint inside and outside the chain link.

[0021] (2) The present invention transports paint to the liquid filling tube through the connecting tube. When the coating roller assembly moves, the paint in the liquid filling tube is transported to the liquid absorbing cotton sleeve, so that it soaks the paint on the front side of the chain body, thereby improving the uniformity of the paint on the front and back sides of the chain body. When the coating roller assembly stops moving, the paint in the liquid filling tube stops being transported to the liquid absorbing cotton sleeve, thereby preventing the paint from being deposited on a part of the chain body, resulting in uneven paint on the part of the chain body.

[0022] (3) There is a gap between the first hook and the second hook in the present invention. When one end of the chain body is hung on the first hook, the other end of the chain body is wrapped around the coating roller assembly for one circle and then hung on the second hook. At this time, there is a gap at the part where the chain body is wrapped around the coating roller assembly, thereby avoiding friction between the chain body wrapped around the coating roller assembly, thereby ensuring the painting effect of the chain body.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-Figure 4The purpose of the present invention can be achieved through the following technical solutions: a metal chain surface spraying device, which includes a box body 1, and a fixed component 2 is installed on the two side walls of the box body 1, and the fixed component 2 is used to hang a chain body 6. A transmission component 4 is installed on the box body 1, and the transmission component 4 includes a sliding box 41 and a transmission plate 43. The sliding box 41 and the transmission plate 43 are slidably matched. A spraying component 3 is installed on the transmission plate 43, and the spraying component 3 includes a mounting plate 34. A coating roller component 5 is rotatably installed on the mounting plate 34, and the coating roller component 5 is located at the bottom of the spraying component 3. One end of the chain body 6 is hung on the fixed component 2 on one side of the box body 1, and the other end of the chain body 6 is hung on the fixed component 2 on the other side of the box body 1 after being wound around the coating roller component 5.

[0035] Specifically, the sliding box 41 is provided with a motor 42 , and the motor 42 is connected to a transmission plate 43 via a screw rod.

[0036] It should be noted that before use, one end of the chain body 6 is hung on the hook 1 23, the other end of the chain body 6 is wound around the roller assembly 5, and then hung on the hook 2 24, and then the spacing between the hook 1 23 and the hook 2 24 is adjusted by twisting the rotating block 22, thereby adjusting the tension of the chain body 6. The reason why the chain body 6 is wound around the roller assembly 5 in the present invention is as follows: when the chain body 6 is not in contact with the roller assembly 5, the surface of the chain body 6 sprayed by the spraying assembly 3 is the front side; after the chain body 6 is in contact with the roller assembly 5, the front side of the chain body 6 is in contact with the roller assembly 5, and at this time, the surface of the chain body 6 sprayed by the spraying assembly 3 is the back side. Therefore, this scheme realizes the overall spraying of the chain body 6 by winding the chain body 6 around the roller assembly 5, thereby replacing the method of driving the chain body 6 to rotate by the rotating motor in the prior art. Compared with the prior art, this scheme can save equipment energy consumption and reduce the failure rate of the equipment.

[0037] When in use, the spray assembly 3 and the motor 42 are started, the motor 42 drives the transmission plate 43 to slide along the sliding box 41, and the transmission plate 43 drives the spray assembly 3 and the roller assembly 5 to move synchronously, see Figure 8Since the coating roller assembly 5 is rotatably mounted on the mounting plate 34, when the coating roller assembly 5 moves, the chain body 6 will rotate along the surface of the coating roller assembly 5 as the coating roller assembly 5 moves. When the chain body 6 is not in contact with the coating roller assembly 5, the chain links are in a tensioned state, and the connection between the chain links remains unchanged. When the chain body 6 is in contact with the coating roller assembly 5, the chain links rotate, and the connection between the chain links changes dynamically, thereby ensuring that the spraying assembly 3 can spray the connection between the chain links, solving the problem that the prior art is difficult to spray the connection between the chain links. Since the spraying assembly 3 sprays paint vertically downward, when the chain link passes through the horizontal part of the coating roller assembly 5, the chain link is perpendicular to the side wall of the coating roller assembly 5. At this time, the spraying assembly 3 can specifically spray the inside of the chain, improving the uniformity of the paint inside and outside the chain link.

[0038] See also Figure 4-Figure 6 The coating roller assembly 5 includes a liquid filling tube 51, a liquid outlet sleeve 52 and a liquid absorbing cotton sleeve 53. A connecting pipe mouth 513 is installed on the side wall of the liquid filling tube 51. The connecting pipe mouth 513 is connected to the connecting pipe 35 and is rotatably connected to the mounting plate 34. A rotating block 511 is arranged on the liquid filling tube 51. A flow channel 512 is arranged on the rotating block 511. The flow channel 512 is connected to the liquid filling tube 51. A rotating groove 521 is arranged on the liquid outlet sleeve 52. Two liquid outlet holes 522 are arranged on the rotating groove 521. The two liquid outlet holes 522 are separated by a blocking plate 523. The two side walls of the rotating groove 521 are respectively connected to the rotating block 511 through two springs 524. The liquid absorbing cotton sleeve 53 is adhered to the outer wall of the liquid outlet sleeve 52.

[0039] It should be noted that the paint liquid in the liquid storage tank 31 is transported to the liquid filling pipe 51 through the connecting pipe 35 and the connecting pipe port 513. A plurality of spray heads are installed on the main pipe 33.

[0040] Specifically, the spray assembly 3 further includes a liquid storage tank 31 and a main pipe 33 . The liquid storage tank 31 is connected to the main pipe 33 via a branch pipe 32 , and the liquid storage tank 31 is connected to the coating roller assembly 5 via a connecting pipe 35 .

[0041] It should be noted that see Figure 8 When the chain body 6 is not in contact with the coating roller assembly 5, the surface of the chain body 6 sprayed by the nozzle is the front surface; after the chain body 6 is in contact with the coating roller assembly 5, the front surface of the chain body 6 is in contact with the coating roller assembly 5, and the surface of the chain body 6 sprayed by the nozzle is the back surface. Since the chain body 6 wound on the coating roller assembly 5 is closer to the nozzle, the spraying effect on the back surface of the chain body 6 is better than that on the front surface of the chain body 6, which easily leads to uneven spraying on the front and back surfaces of the chain body 6.

[0042] The filling tube 51 and the liquid outlet sleeve 52 are rotatably matched, and the filling tube 51 is rotatably mounted on the mounting plate 34, wherein the filling tube 51 and the liquid outlet sleeve 52 have different rotation damping, the filling tube 51 has a larger rotation damping, and the liquid outlet sleeve 52 has a smaller rotation damping. Figure 6 When the coating roller assembly 5 moves, the chain body 6 drives the liquid outlet sleeve 52 to rotate first. Since the rotation damping of the liquid filling tube 51 is large, the liquid outlet sleeve 52 rotates while the liquid filling tube 51 is relatively fixed. At this time, the spring 524 on the liquid outlet sleeve 52 compresses and presses the rotating block 511. When the spring 524 is compressed to the limit, the liquid outlet sleeve 52 rotates to drive the liquid filling tube 51 to rotate synchronously. At this time, the flow channel 512 is aligned with the liquid outlet hole 522, and the paint liquid in the liquid filling tube 51 flows out through the flow channel 512 and the liquid outlet hole 522 and hits the liquid absorbing cotton sleeve 53. During the infiltration, when the front side of the chain body 6 contacts the absorbent cotton sleeve 53, the absorbent cotton sleeve 53 will infiltrate the paint on the front side of the chain body 6 to improve the uniformity of the paint on the front and back sides of the chain body 6; when the coating roller assembly 5 stops moving, the spring 524 rebounds to drive the flow channel 512 out of the liquid outlet hole 522; at this time, the flow channel 512 is blocked by the flow blocking plate 523, and the paint in the filling tube 51 stops being transported to the absorbent cotton sleeve 53, to avoid the paint being deposited in a part of the chain body 6, resulting in uneven paint in a part of the chain body 6. Therefore, the present invention transports paint to the filling tube 51 through the connecting tube 35. When the coating roller assembly 5 moves, the paint in the filling tube 51 is transported to the absorbent cotton sleeve 53, so that it soaks the paint on the front side of the chain body 6, thereby improving the uniformity of the paint on the front and back sides of the chain body 6. When the coating roller assembly 5 stops moving, the paint in the filling tube 51 stops being transported to the absorbent cotton sleeve 53, thereby preventing the paint from being deposited in a part of the chain body 6, resulting in uneven paint in a part of the chain body 6.

[0043] It should be noted that see Figure 8 As the coating roller assembly 5 moves, the chain body 6 rotates along the coating roller assembly 5, and at the same time, the chain body 6 also moves laterally along the coating roller assembly 5. During the lateral movement of the chain body 6, the paint absorbed by the liquid-absorbing cotton sleeve 53 can continuously infiltrate the front of the chain body 6. If the chain body 6 cannot move laterally, the chain body 6 can only be infiltrated at a local position of the liquid-absorbing cotton sleeve 53. The front of the chain body 6 is infiltrated at one position of the liquid-absorbing cotton sleeve 53 for a long time, which is prone to insufficient paint supply to the liquid-absorbing cotton sleeve 53, resulting in reduced infiltration effect. This solution can ensure that the chain body 6 moves laterally, so that the chain body 6 can move along the axial direction of the liquid-absorbing cotton sleeve 53, avoiding the phenomenon of insufficient paint supply to the liquid-absorbing cotton sleeve 53.

[0044] See also Figure 7The fixing assembly 2 includes a hook 23 and a hook 24, which are respectively arranged on the two side walls of the box body 1. The hook 23 and the hook 24 are both provided with a threaded rod 21, which is threadedly connected to the box body 1, and a rotating block 22 is installed on the threaded rod 21.

[0045] Specifically, the first hook 23 and the second hook 24 are of the same height, and there is a gap between the first hook 23 and the second hook 24.

[0046] It should be noted that see Figure 7 and Figure 8 Since there is a gap between the hook 1 23 and the hook 2 24, when one end of the chain body 6 is hung on the hook 1 23, the other end of the chain body 6 is wound around the coating roller assembly 5, and then it is hung on the hook 2 24. At this time, the state of the chain body 6 winding around the coating roller assembly 5 is as follows: Figure 8 As shown, there is a gap at the portion where the chain body 6 is wound around the coating roller assembly 5, thereby avoiding friction between the chain body 6 wound around the coating roller assembly 5, thereby ensuring the painting effect of the chain body 6.

[0047] See also Figure 1-Figure 6 As shown, the present invention is a metal chain surface spraying process, the process is applied to the metal chain surface spraying device as described in the above embodiment, and the process includes the following steps:

[0048] Step S1: hang one end of the chain body 6 on the hook 1 23, and the other end of the chain body 6 is wrapped around the coating roller assembly 5, and then hung on the hook 2 24;

[0049] Step S2: starting the spraying assembly 3 and the motor 42, the motor 42 drives the transmission plate 43 to slide along the sliding box 41, and the transmission plate 43 drives the spraying assembly 3 and the coating roller assembly 5 to move synchronously;

[0050] Step S3: When the coating roller assembly 5 moves, the chain body 6 will rotate along the surface of the coating roller assembly 5 as the coating roller assembly 5 moves. When the chain body 6 is not in contact with the coating roller assembly 5, the chain links are in a tensioned state, and the connection between the chain links remains unchanged. When the chain body 6 is in contact with the coating roller assembly 5, the chain links rotate, and the connection between the chain links changes dynamically. At this time, the spraying assembly 3 can spray the connection between the chain links.

[0051] like Figure 4-Figure 6 As shown, as a preferred embodiment of the present invention, step S3 specifically includes the following steps:

[0052] Step S31: When the coating roller assembly 5 moves, the chain body 6 drives the liquid outlet sleeve 52 to rotate first. Since the rotation damping of the liquid filling tube 51 is relatively large, when the liquid outlet sleeve 52 rotates, the liquid filling tube 51 is relatively fixed. At this time, the spring 524 on the liquid outlet sleeve 52 compresses and presses the rotating block 511. When the spring 524 is compressed to the limit, the liquid outlet sleeve 52 rotates to drive the liquid filling tube 51 to rotate synchronously. At this time, the flow channel 512 is aligned with the liquid outlet hole 522;

[0053] Step S32: the paint liquid in the filling tube 51 flows out through the flow channel 512 and the liquid outlet hole 522 and infiltrates the liquid absorbing cotton sleeve 53. When the front side of the chain body 6 contacts the liquid absorbing cotton sleeve 53, the liquid absorbing cotton sleeve 53 infiltrates the paint on the front side of the chain body 6;

[0054] Step S33: When the coating roller assembly 5 stops moving, the spring 524 rebounds to drive the flow channel 512 away from the liquid outlet 522. At this time, the flow channel 512 is blocked by the flow blocking plate 523, and the paint in the liquid filling tube 51 stops being transported to the liquid absorbing cotton sleeve 53.

[0055] The implementation principle of the present invention is:

[0056] Before use, hang one end of the chain body 6 on the hook 1 23, wrap the other end of the chain body 6 around the coating roller assembly 5, and then hang it on the hook 2 24, and then adjust the distance between the hook 1 23 and the hook 2 24 by twisting the rotating block 22, thereby adjusting the tension of the chain body 6.

[0057] When in use, the spray assembly 3 and the motor 42 are started, the motor 42 drives the transmission plate 43 to slide along the sliding box 41, and the transmission plate 43 drives the spray assembly 3 and the roller assembly 5 to move synchronously, see Figure 8 Since the coating roller assembly 5 is rotatably mounted on the mounting plate 34, when the coating roller assembly 5 moves, the chain body 6 will rotate along the surface of the coating roller assembly 5 as the coating roller assembly 5 moves. When the chain body 6 is not in contact with the coating roller assembly 5, the chain links are in a tensioned state, and the connection between the chain links remains unchanged. When the chain body 6 is in contact with the coating roller assembly 5, the chain links rotate, and the connection between the chain links changes dynamically, thereby ensuring that the spraying assembly 3 can spray the connection between the chain links, solving the problem that the prior art is difficult to spray the connection between the chain links. Since the spraying assembly 3 sprays paint vertically downward, when the chain link passes through the horizontal part of the coating roller assembly 5, the chain link is perpendicular to the side wall of the coating roller assembly 5. At this time, the spraying assembly 3 can specifically spray the inside of the chain, improving the uniformity of the paint inside and outside the chain link.

[0058] When the coating roller assembly 5 moves, the chain body 6 drives the liquid outlet sleeve 52 to rotate first. Since the rotation damping of the liquid filling tube 51 is large, the liquid outlet sleeve 52 is relatively fixed when it rotates. At this time, the spring 524 on the liquid outlet sleeve 52 is compressed and presses the rotating block 511. When the spring 524 is compressed to the limit, the liquid outlet sleeve 52 rotates to drive the liquid filling tube 51 to rotate synchronously. At this time, the flow channel 512 is aligned with the liquid outlet hole 522, and the paint liquid in the liquid filling tube 51 flows out through the flow channel 512 and the liquid outlet hole 522 and enters the liquid absorbing cotton sleeve 53. When the front side of the chain body 6 contacts the absorbent cotton sleeve 53, the absorbent cotton sleeve 53 will soak the paint on the front side of the chain body 6 to improve the uniformity of the paint on the front and back sides of the chain body 6. When the coating roller assembly 5 stops moving, the spring 524 rebounds and drives the flow channel 512 to separate from the liquid outlet 522. At this time, the flow channel 512 is blocked by the flow blocking plate 523, and the paint in the filling tube 51 stops being transported to the absorbent cotton sleeve 53, so as to avoid the paint being deposited in a part of the chain body 6, resulting in uneven paint in a part of the chain body 6.

[0059] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.

A metal chain surface spraying device according to claim 3, characterized in that: The fixing assembly (2) comprises a first hook (23) and a second hook (24), the first hook (23) and the second hook (24) being arranged on two side walls of the box body (1) respectively, the first hook (23) and the second hook (24) being provided with a threaded rod (21), the threaded rod (21) being threadedly connected to the box body (1), and a rotating block (22) being mounted on the threaded rod (21).

5. A metal chain surface spraying device according to claim 4, characterized in that: The first hook (23) and the second hook (24) are of the same height, and there is a gap between the first hook (23) and the second hook (24).

6. A metal chain surface spray painting process, characterized in that: The process is applied to the metal chain surface spray painting device as described in claim 5 above, and the process includes the following steps: Step S1: Hang one end of the chain body (6) on the first hook (23), wrap the other end of the chain body (6) around the coating roller assembly (5), and then hang it on the second hook (24); Step S2: starting the spraying assembly (3) and the motor (42), the motor (42) driving the transmission plate (43) to slide along the sliding box (41), and the transmission plate (43) driving the spraying assembly (3) and the coating roller assembly (5) to move synchronously; Step S3: When the coating roller assembly (5) moves, the chain body (6) rotates along the surface of the coating roller assembly (5) as the coating roller assembly (5) moves. When the chain body (6) is not in contact with the coating roller assembly (5), the chain links are in a tensioned state, and the connection between the chain links remains unchanged. When the chain body (6) is in contact with the coating roller assembly (5), the chain links rotate, and the connection between the chain links changes dynamically. At this time, the spraying assembly (3) can spray the connection between the chain links.

7. A metal chain surface spray painting process according to claim 6, characterized in that: The step S3 specifically comprises the following steps: Step S31: When the coating roller assembly (5) moves, the chain body (6) drives the liquid outlet sleeve (52) to rotate first. Since the rotational damping of the liquid filling tube (51) is relatively large, when the liquid outlet sleeve (52) rotates, the liquid filling tube (51) is relatively fixed. At this time, the spring (524) on the liquid outlet sleeve (52) compresses and presses the rotating block (511). When the spring (524) is compressed to the limit, the liquid outlet sleeve (52) rotates and drives the liquid filling tube (51) to rotate synchronously. At this time, the flow channel (512) is aligned with the liquid outlet hole (522); Step S32: the paint liquid in the filling tube (51) flows out through the flow channel (512) and the liquid outlet hole (522) and infiltrates the liquid absorbing cotton sleeve (53). When the front side of the chain body (6) contacts the liquid absorbing cotton sleeve (53), the liquid absorbing cotton sleeve (53) infiltrates the paint on the front side of the chain body (6); Step S33: When the coating roller assembly (5) stops moving, the spring (524) rebounds to drive the flow channel (512) away from the liquid outlet hole (522). At this time, the flow channel (512) is blocked by the flow blocking plate (523), and the paint in the liquid filling tube (51) stops being transported to the liquid absorbing cotton sleeve (53).
