Description

TECHNICAL FIELD

[0001] The present application relates to a dust cleaning system for a sprayed product. BACKGROUND

[0002] Before the precision surface treatment process such as spraying and coating, the product surface must be thoroughly cleaned to remove dust, fibers and other small contaminants. If these contaminants are not removed, they will directly affect the adhesion of the coating and the surface quality, resulting in unqualified products.

[0003] Currently, common online dust removal methods include ion wind dust removal, brush cleaning and dust-free cloth wiping. Among them, dust-free cloth wiping is widely used because of its good cleaning effect and relatively low cost. The traditional dust-free cloth wiping device usually needs an independent driving motor and control system to drive the winding mechanism, and the wiping section needs to be replaced regularly. However, this method has the following disadvantages: 1) It needs an additional power source and electrical control system, increasing the cost of equipment; 2) The control logic needs to match the production line beat, increasing the difficulty of debugging and maintenance; 3) The energy consumption is relatively high.

[0004] Therefore, there is an urgent need for a dust cleaning solution that is reasonable in structure, does not require independent driving, and can be automatically synchronized with the production line. SUMMARY

[0015] The specific embodiments of the present application will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present application, and cannot be used to limit the protection scope of the present application.

[0016] The technical solutions of the specific embodiments of the present application are as follows: In one specific embodiment, as shown in Figure 1 and Figure 2 A dust removal cleaning system for a sprayed product includes a conveying device 1 and a dust-free cloth wiping device. The conveying device 1 is provided with a plurality of positioning jigs 2, which are used to move with the conveying device 1 and respectively load products 100. The dust-free cloth wiping device includes a fixed plate 3 and a dust-free cloth wiping assembly. The fixed plate 3 is arranged on one side of the conveying device 1, and the dust-free cloth wiping assembly is arranged above the conveying device 1. The dust-free cloth wiping assembly includes a winding roller 4, an unwinding roller 5, and a dust-free cloth 6 connected between the winding roller 4 and the unwinding roller 5. The dust-free cloth 6 is used to wipe and remove dust from the top surface of the product 100 passing below it during the conveying process. The winding roller 4 is rotatably connected to the fixed plate 3 through a winding shaft 7. The unwinding roller 5 is rotatably connected to the fixed plate 3 through an unwinding shaft 8. Along the conveying direction of the conveying device 1, the winding shaft 7 is located upstream of the unwinding shaft 8. Both the winding shaft 7 and the unwinding shaft 8 are damping shafts, and the winding shaft 7 can only rotate in a first direction opposite to the conveying direction of the conveying device 1. A winding gear 9 is sleeved on the winding shaft 7. The winding gear 9 is located between the fixed plate 4 and the winding roller 4, and a transition gear 10 is engagedly connected below the winding gear 9. The transition gear 10 is rotatably connected to the fixed plate 3. The top of the positioning jig 2 is provided with a rack 12 through a support 11. Along the conveying direction of the conveying device 1, the rack 12 is located downstream of the product 100. The rack 12 is used to engage or disengage with the transition gear 10. When the rack 12 engages with the transition gear 10, the rack 12 will drive the winding shaft 7 to rotate in the first direction through the transition gear 10 and the winding gear 9.

[0017] Adopting the above scheme: when the product 100 moves to the position below the dustless cloth 6, the top surface of the product 100 is in contact with the dustless cloth 6, and the dust is wiped off. After the product 100 continues to move and is separated from the dustless cloth 6, the rack 12 behind the positioning jig 2 is just in the position to engage with the transition gear 10. The rack 12 in motion drives the winding shaft 7 to rotate in the first direction through the transition gear 10 and the winding gear 9, so as to drive the winding roller 4 to rotate, and the section of the dustless cloth 6 that has wiped the product 100 is wound up, and at the same time a new section of clean dustless cloth 6 is pulled out from the unwinding roller 5. When the positioning jig 2 passes completely, the rack 12 is disengaged from the transition gear 10, and the winding operation stops. The system returns to the waiting state until the next positioning jig 2 reaches the dustless cloth wiping device, and the cycle is repeated to realize the wiping and dust removal of the product 100 and the automatic replacement of the dustless cloth.

[0018] In another specific embodiment, as shown in Figure 1 the fixing plate 3 is rotatably connected with two guide rollers 13, the two guide rollers 13 are located between the winding roller 4 and the unwinding roller 5, and the two guide rollers 13 are used to press the dustless cloth 6 against the top surface of the product 100.

[0019] Adopting the above scheme: after the dustless cloth 6 is pulled out from the unwinding roller 5, it is wound downward through the lower part of the first guide roller 13, then horizontally extended to pass through the lower part of the second guide roller 13, and finally led upward to the winding roller 4. In this way, between the two guide rollers 13, the dustless cloth 6 forms a flat and stable wiping plane, the height of which is accurately set to ensure that it can be moderately pressed against the top surface of the product 100 passing below.

[0020] In another specific embodiment, as shown in Figure 3 the winding shaft 7 is provided with a ratchet assembly, the ratchet assembly includes a ratchet 14 and a pawl 15, the ratchet 14 is sleeved on the winding shaft 7, and the ratchet 14 is located between the fixing plate 3 and the winding gear 9, one end of the pawl 15 is rotatably connected to the fixing plate 3 through a shaft pin 16, and the other end is clamped in the tooth groove of the ratchet 14, and a torsional spring is arranged between the pawl 15 and the shaft pin 16 to force the pawl 15 to be clamped into the tooth groove of the ratchet 14.

[0021] Adopting the above scheme: when the product 100 moves in the conveying direction and contacts the dustless cloth 6, a friction force in the same direction as the conveying direction is generated on the dustless cloth 6. If the winding roller 4 can rotate freely, the friction force has a tendency to pull the dustless cloth 6 and drive the winding roller 4 to reverse. By setting the ratchet assembly, the winding roller 4 can only rotate in the first direction for winding, effectively locking the reverse movement, thereby avoiding the dustless cloth 6 from being accidentally pulled, and ensuring the stability of the wiping process.

[0022] In another specific embodiment, the plurality of positioning jigs 2 are arranged equidistantly along the conveying direction of the conveying device 1.

[0023] In another specific embodiment, the top of the positioning jig 2 is provided with a product positioning groove.

[0024] The above scheme is adopted: so as to position the product 100.

[0025] The above only describes the preferred embodiments of the present application, and it should be noted that, for those skilled in the art, without departing from the technical principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered as the protection scope of the present application.
