[0008] Through the above technical solution, the structure of the independent power source configuration drives the generation of differentiated speed control effect of the two sets of sand belts.

[0009] As a further improvement to the above solution, the connecting gear is slidably installed inside the transverse limiting groove, and a first connecting rod is rotatably connected to the outer surface of the connecting gear. The side of the first connecting rod away from the connecting gear is rotatably connected to the outer surface of the driven gear.

[0010] Through the above technical solution, the structure of gear and rack meshing transmission enables the precise conversion of linear displacement into rotational motion.

[0011] As a further improvement to the above solution, the driven gear is slidably installed inside the longitudinal limiting groove, and the driven gear is fixedly connected to the outer surface of the first grinding roller.

[0012] Through the above technical solution, the rigid direct-connection structure minimizes power loss and eliminates synchronization errors.

[0015] As a further improvement to the above solution, the drive gear is slidably installed inside the longitudinal limiting groove, and the drive gear is fixedly connected to the outer surface of the second grinding roller.

[0016] Through the above technical solutions, the coaxial rotation design of the structure enables the balanced distribution of inertial load and the effect of vibration suppression.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes a structure where a cylinder drives a push rod to retract and a connecting gear slides along a transverse limiting groove. This structure causes the driven gear and the drive gear to move synchronously in opposite directions within a longitudinal limiting groove. This design allows the distance between the first and second sanding rollers to automatically adapt to the thickness of the wood. Combined with the dual grinding action of the first and second sanding belts, it achieves uniform surface roughness treatment for solid wood of different materials. This structure breaks through the limitations of traditional fixed sanders and can meet the continuous processing needs of curved or irregularly shaped workpieces.

[0018] This invention utilizes a structure where a conveyor motor drives a conveyor belt and a transmission chain to synchronously rotate multiple dust-collecting and adsorption rollers. This creates a synergistic effect between directional airflow and electrostatic adsorption. The solution employs a graded filtration mechanism: first, a high-speed rotating brush layer sweeps away large particles of debris, and then a negative pressure adsorption zone captures fine dust, ultimately ensuring that no residual particles remain on the surface of the solid wood after sanding. The specially designed staggered roller group forms a closed dust removal channel, effectively preventing secondary dust pollution of the treated workpiece surface. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example:

[0022] Please combine Figure 1-5 This embodiment of a five-head sanding and coating equipment for solid wood coating lines includes an installation component 1. The installation component 1 includes a mounting frame 101, a mounting base 102 fixedly connected to the outer surface of the mounting frame 101, a longitudinal limiting groove 103 formed inside the mounting frame 101, and a transverse limiting groove 104 formed on the outer surface of the mounting frame 101 between the two longitudinal limiting grooves 103. It also includes: The conveying assembly 2 includes a conveying roller 201 rotatably connected to the inner wall of the mounting frame 101, and a conveying belt 203 rotatably connected to the outer surface of the connecting frame 202 is provided on the outer surface of the conveying roller 201. Grinding assembly 3 includes a first grinding roller 301 and a first driven roller 302 slidably mounted inside the longitudinal limiting groove 103. A second grinding roller 304 and a second driven roller 305 are slidably mounted inside the longitudinal limiting groove 103 at the bottom of the first grinding roller 301. The spacing adjustment component 4 includes a cylinder 401 fixedly connected inside the mounting base 102. The output end of the cylinder 401 is fixedly connected to a push rod 402, and a connecting gear 403 is rotatably connected inside the push rod 402.

[0023] A connecting frame 202 is fixedly connected to one side of the mounting frame 101. A conveyor belt 203 is rotatably connected inside the connecting frame 202 via a conveyor motor. A dust removal adsorption roller 204 is rotatably connected inside the connecting frame 202 via a motor. The two dust removal adsorption rollers 204 are connected by a transmission chain 205.

[0024] A first sanding belt 303 is sleeved on the outer surface of the first grinding roller 301 and the first driven roller 302. A second sanding belt 306 is sleeved on the outer surface of the second grinding roller 304 and the first driven roller 302. A servo motor 307 is slidably mounted on the outer surface of the mounting bracket 101. The output end of the servo motor 307 is fixedly connected to the second grinding roller 304.

[0025] The connecting gear 403 is slidably installed inside the transverse limiting groove 104. The outer surface of the connecting gear 403 is rotatably connected to the first connecting rod 404. The side of the first connecting rod 404 away from the connecting gear 403 is rotatably connected to the outer surface of the driven gear 405.

[0026] The driven gear 405 is slidably installed inside the longitudinal limiting groove 103, and the driven gear 405 is fixedly connected to the outer surface of the first grinding roller 301.

[0027] The front end of the first connecting rod 404 is provided with a second connecting rod 406 rotatably connected to the outer surface of the connecting gear 403, and a drive gear 407 is rotatably connected to the side of the second connecting rod 406 away from the connecting gear 403.

[0028] The drive gear 407 is slidably installed inside the longitudinal limiting groove 103, and the drive gear 407 is fixedly connected to the outer surface of the second grinding roller 304.

[0029] The connecting gear 403 is connected to the driven gear 405 and the driving gear 407 by the first connecting rod 404 and the second connecting rod 406 respectively. This ensures that when the connecting gear 403 slides, it drives the driven gear 405 and the driving gear 407 to slide away from each other in the longitudinal limiting groove 103, thus ensuring that the distance between the first grinding roller 301 and the second grinding roller 304 is adjusted.

[0030] The implementation principle of the five-head sanding and grouting equipment for a solid wood coating line in this application embodiment is as follows: Driven by cylinder 401, the push rod 402 retracts. Since a connecting gear 403 is rotatably connected inside the push rod 402, when the push rod 402 retracts, it drives the connecting gear 403 to slide within the transverse limiting groove 104. The connecting gear 403 is connected to the driven gear 405 and the driving gear 407 respectively by a first connecting rod 404 and a second connecting rod 406. This ensures that when the connecting gear 403 slides, it drives the driven gear 405 and the driving gear 407 to slide away from each other within the longitudinal limiting groove 103. The movement ensures that the distance between the first sanding roller 301 and the second sanding roller 304 is adjusted. The first sanding belt 303 and the second sanding belt 306 can be used to sand the solid wood. After the sanding is completed, the solid wood naturally falls onto the surface of the conveyor belt 203. The conveyor motor on the outer surface of the connecting frame 202 drives the sanded solid wood on the surface of the conveyor belt 203 to be conveyed. As the conveyor belt 203 is conveyed, the dust removal and adsorption roller 204 is driven to rotate under the drive of the motor. The transmission chain 205 can drive multiple dust removal and adsorption rollers 204 to rotate, ensuring that the wood chips or dust on the surface of the solid wood are adsorbed, and ensuring the cleanliness of the solid wood surface.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
