Description

Technical Field

[0001] The invention belongs to the technical field of louver blade sanding, in particular to a line sanding device for louver blade processing. Background Art

[0002] Shutters are a type of window. Vertical shutters are called mullion windows, while horizontal shutters are called horizontal mullion windows. Shutters are a type of soft furnishing for new homes. They are generally used in new buildings and renovations. Shutter blades are generally made of wood, glass, and aluminum alloy, so they can withstand the erosion of sunlight, wind, rain, and dust.

[0003] In the traditional process, the surface is generally ground first and then the sides are processed. However, the side structure of the louver is weak.

[0021] In the process of reciprocating translation of the screw rod, the present invention also drives the connected piston T-rod to perform fitting pulling and squeezing movements in the piston cylinder. Therefore, during the pulling and drawing process, the dust and debris generated when the louver blades are polished will be sucked and collected through the suction tube installed with a one-way valve and the air exhaust expansion head on the top of the suction tube, so as to prevent them from floating in the work space, causing physical discomfort to the staff and possibly affecting the normal polishing and sanding operations of the louver blades. When the piston T-rod is passively pushed to generate extrusion force, the previously collected dust and debris will be passed through the pipeline installed with a one-way valve and input into the air bag for unified collection, which is convenient for subsequent cleaning and treatment.

DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0033] like Figures 1 to 7As shown, the present invention provides a line sanding device for processing louvers, comprising a grinding and conveying machine 1, a secondary conveying machine 101 being provided on one side of the grinding and conveying machine 1, three roller cylinders 102 being movably sleeved in the grinding and conveying machine 1 and the secondary conveying machine 101, and a plurality of rubber convex modules 103 being fixedly connected to the surfaces of the grinding and conveying machine 1 and the secondary conveying machine 101, and a sanding section 2 being provided between the grinding and conveying machine 1 and the secondary conveying machine 101;

[0034] The sanding and polishing section 2 includes a set of symmetrically arranged L-shaped support slides 216. Two engaging assemblies 218 are rotatably connected to the inner wall of each set of L-shaped support slides 216. The bottom ends of the two engaging assemblies 218 are each provided with a sanding wheel 220 for simultaneously sanding the upper and lower surfaces of the louver blades.

[0035] A grinding and polishing disc 203 is fixedly connected to both sides of the rod body of one of the roller cylinders 102, which is used to grind the two end sides of the louver blades first.

[0036] The above scheme is adopted: by starting the motor 202 installed on the L-shaped support plate 201, the grinding and conveying machine 1 is made to perform the conveying operation, that is, the multiple roller barrels 102 provided in the grinding and conveying machine 1 will be driven to rotate accordingly, and one of the driven roller barrels 102 will synchronously drive the two grinding and throwing discs 203 to rotate, thereby grinding the side of the louver being conveyed on the surface of the grinding and conveying machine 1. The multiple rubber convex modules 103 installed on the grinding and conveying machine 1 can increase the friction between the louver and the conveyor when it is conveyed, thereby preventing the conveying from deviating, and grinding the side of the louver first can prevent the prior art from grinding the upper and lower ends of the louver and then grinding the louver. The side grinding may cause the side plates of the louver blades to be easily broken. The subsequent translation of the tooth plate will drive the connected L-shaped support slide 216 to translate synchronously, which can drive the installed grinding wheel 220 to translate. During the translation process, the grinding wheel 220 will perform a flat-sweeping grinding on the surface of the louver blade when it contacts the translationally transmitted louver blade. In addition, when the L-shaped support slide 216 is passively translated on the special-shaped support rod 217, the spur gear installed on the L-shaped support slide 216 can rotate when it engages with the U-shaped tooth plate, thereby driving the corresponding grinding wheel 220 through the rotating rod 219 to perform flat-sweeping and rotating grinding, which can significantly improve the processing quality and efficiency.

[0037] The sanding and polishing part 2 also includes an L-shaped support plate 201 fixedly connected to a plate on one side of the top of the sanding and conveying machine 1. A motor 202 is fixedly connected to the plate of the L-shaped support plate 201. The motor 202 is fixedly connected to a roller cylinder 102. Each roller cylinder 102 located at the inner wall of each end of the sanding and conveying machine 1 is specifically and fixedly connected to a synchronous belt 204. A roller cylinder 102 away from the motor 202 is fixedly connected to a rotating wheel 205. The outer wall of the other end of the rotating wheel 205 is fixed. It is fixedly connected with a rotating shaft 206, and a sleeve plate 207 is fixedly connected to the shaft rod of the rotating shaft 206. The other side plate of the sleeve plate 207 is fixedly connected with a rotating shaft 208. The shaft rod of the rotating shaft 208 is movably sleeved with a sleeve plate 209. The other side plate of the sleeve plate 209 is movably sleeved with a U-shaped shaft plate 210. The bottom end of the U-shaped shaft plate 210 is slidably connected with an L-shaped slide plate 211. The bottom end outer wall of the L-shaped slide plate 211 and the frame of the grinding and transmission machine 1 are jointly and fixedly connected with a connecting plate.

[0038] Adopting the above scheme: the operation of the motor 202 will drive the synchronous belt 204 installed on two of the roller cylinders 102, and then drive the wheel 205, the rotating shaft 206 and the sleeve plate 1 207 to rotate rapidly at high speed. The rotation of the sleeve plate 1 207 will inevitably drive the sleeve plate 2 209 to swing back and forth through the rotating shaft 2 208, thereby repeatedly stretching the U-shaped shaft plate 210, causing it to slide on the upper limit of the L-shaped slide plate 211.

[0039] The U-shaped shaft plate 210 is also fixedly connected to a screw 212, and the screw 212 and a section of the L-shaped slide plate 211 are slidably connected. A sleeve 213 is movably sleeved in the inner wall of the plate body of one end of the L-shaped slide plate 211, and the inner wall of the sleeve 213 is threadedly connected to the screw 212, and the outer wall of the sleeve 213 is fixedly connected to a meshing component 214; the meshing component 214 is specifically composed of a spur gear and a toothed plate meshed with it. One end plate body of the toothed plate is fixedly connected to the plate body of the L-shaped support slide plate 216, and a limiting clamping plate 215 is fixedly connected to the top side plate body of the L-shaped slide plate 211, and the inner wall of the limiting clamping plate 215 is fitly connected to the meshing component 214, and a special-shaped support rod 217 is fixedly connected to the grinding and transmission machine tool 1, and the rod body of the special-shaped support rod 217 and the plate body of the L-shaped support slide plate 216 are slidably connected;

[0040] Each group of meshing components 218 is specifically composed of two spur gears and a U-shaped tooth plate meshingly connected thereto. The U-shaped tooth plate and the plate body of the L-shaped support slide 216 are fitted and slidably connected, and a rotating rod 219 is fixedly connected to the two spur gears. The bottom end rod bodies of the two rotating rods 219 are fixedly connected to the grinding wheel 220, and the rod bodies of the two rotating rods 219 are movably connected to the plate body of the L-shaped support slide 216. A special-shaped support rod 221 is fixedly connected to the plate body of the U-shaped tooth plate, and the other side rod body of the special-shaped support rod 221 is fixedly connected to the grinding transmission machine 1.

[0041] The above scheme is adopted: the passive translation of the U-shaped shaft plate 210 will also drive the screw 212 to translate in the sleeve 213, thereby driving the sleeve 213 to rotate in a fixed manner on the plate body of the L-shaped slide plate 211, and the sleeve 213 in the rotating state will drive the spur gear and the tooth plate in the meshing component 1 214 to engage with each other to generate a circular to linear motion trajectory, and the meshing portion between the two will be blocked by the limiting card plate 215, and the translation of the tooth plate will drive the connected L-shaped support slide plate 216 to translate synchronously, which can drive the installed grinding wheel 220 to translate. During the translation process, the grinding wheel 220 will contact the shutter transmitted by the translation. When the L-shaped support plate 216 is moved horizontally on the special-shaped support rod 1 217, the surface is polished in a flat sweeping manner. In the process of the L-shaped support slide 216 passively moving horizontally on the special-shaped support rod 1 217, the corresponding meshing component 2 218 installed is also driven to engage with each other for transmission. The spur gear installed on the L-shaped support slide 216 can rotate when engaging with the U-shaped tooth plate, thereby driving the corresponding grinding wheel 220 to perform flat sweeping and rotating grinding through the rotating rod 219, which can significantly improve the processing quality and efficiency, and avoid the regular stripes easily generated by single-direction grinding in the prior art. The rotational motion makes the abrasive cutting trajectory cross in a mesh shape, effectively disperses the wear marks, and avoids the problem of uneven surface finish caused by directional aggregation of textures.

[0042] Two piston T rods 222 are provided on the side of the screw rod 212, and the outer walls of the two piston T rods 222 are fitted with piston cylinders 223. The two end cylinders of the two piston cylinders 223 are respectively fixedly connected with a suction pipe 224 and a delivery pipe 2241, and the two suction pipes 224 and the delivery pipe 2241 are fixedly connected with a one-way valve 226. The bottom pipe bodies of the two delivery pipes 2241 are jointly threadedly connected with an air bag 2242. The other ends of the two suction pipes 224 are fixedly connected with an air pump expansion head 225. The pipe bodies of the two suction pipes 224 are also jointly fixedly connected with a positioning plate 227. One end plate of the positioning plate 227 is fixedly connected to the grinding and transmission machine tool 1. The rod body of the plug T rod 222 is specifically fixedly connected to the screw rod 212, and a block 228 is fixedly connected to the outer wall of the rod body of one end of the piston T rod 222, and an inclined plate 230 is slidably connected to the outer wall of the block 228. The plate body of the inclined plate 230 is fixedly connected to the vertical rod, and a groove connecting plate 229 is movably sleeved on the rod body of the vertical rod. The outer walls of both ends of the groove connecting plate 229 are respectively fixedly connected to the outer walls of the two piston cylinders 223, and a ball shaft 231 is movably sleeved on the rod body of the other piston T rod 222. The other side plate body of the inclined plate 230 is movably sleeved with the ball shaft 231, and a spring 232 is jointly and fixedly connected between the rod body of the other piston T rod 222 and the inner wall of one end of the piston cylinder 223.

[0043] The above scheme is adopted: during the reciprocating translation of the screw 212, the connected piston T-rod 222 will also be driven to perform fitting, pulling, and squeezing movements in the piston cylinder 223. Therefore, during the pulling and drawing process, the dust and debris generated during the grinding of the louver blades will be sucked and collected through the suction pipe 224 equipped with a one-way valve 226 and the air exhaust expansion head 225 on the top of the suction pipe 224 to prevent them from floating in the work space, causing physical discomfort to the staff and possibly affecting the normal grinding and sanding of the louver blades. When the piston T-rod 222 is passively pushed to generate extrusion pressure, the previously collected dust and debris will be passed through the delivery pipe 2241 equipped with a one-way valve 226 and input into the air bag 2242 for unified collection, which is convenient for subsequent cleaning.

[0044] It should be added that the polishing disc 203 and the polishing wheel 220 are both made of fine sand with a particle size of 150. During operation, the meshing assembly 1 214 and the meshing assembly 2 218 can be covered with a protective cover to prevent accidental engagement. The material can be sheet material, rubber material, plastic, etc. The grinding conveying machine 1 and the secondary conveying machine 101 can also be used to limit the transmission of the louver blades in the existing technology. The surface of the U-shaped card plate for the clamping connection needs to be coated with a lubricating film to enable the louver blades to move in a specific direction.

[0045] The grinding wheel 220 is driven to grind the louver blades, and the grinding work is carried out simultaneously on the upper and lower outer walls of the louver blades. Figure 1 As shown, when the louver blades on the grinding and conveying machine 1 are conveyed to the secondary conveying machine 101, they will pass through two sets of meshing components 218, thereby achieving synchronous grinding and sanding operations on the upper and lower surfaces, making the lines of the louver blades smooth and soft.

[0046] The working principle and use process of the present invention are as follows: by starting the motor 202 installed on the L-shaped support plate 201, the grinding and conveying machine 1 is made to perform the conveying operation, that is, the multiple roller barrels 102 provided in the grinding and conveying machine 1 will be driven to rotate accordingly, and one of the driven roller barrels 102 will synchronously drive the two grinding and throwing discs 203 to rotate, thereby being able to perform side grinding on the louver blades being conveyed on the surface of the grinding and conveying machine 1. The multiple rubber convex modules 103 installed on the grinding and conveying machine 1 can increase the friction between the louver blades and the conveying machine 1 when they are being conveyed, thereby preventing conveying deviation, and Grinding the sides of the louver blades first can prevent the situation in the prior art where the upper and lower ends of the louver blades are ground before the sides are ground, which may cause the side plates of the louver blades to be easily broken. At the same time, the operation of the motor 202 will drive the synchronous belt 204 installed on two of the roller barrels 102, and then drive the wheel 205, the rotating shaft 206 and the sleeve plate 207 to rotate rapidly at high speed. The rotation of the sleeve plate 107 will inevitably drive the sleeve plate 209 to swing back and forth through the rotating shaft 208, thereby repeatedly stretching the U-shaped shaft plate 210, causing it to slide on the upper limit of the L-shaped slide plate 211, and as shown in FIG. Figure 3 and Figure 6 As shown, the passive translation of the U-shaped shaft plate 210 will also drive the screw 212 to translate in the sleeve 213, thereby driving the sleeve 213 to rotate in a fixed manner on the plate body of the L-shaped slide plate 211, and the sleeve 213 in the rotating state will drive the spur gear and the tooth plate in the meshing component 1 214 to engage with each other to produce a circular to linear motion trajectory, and the meshing portion between the two will be blocked by the limiting card plate 215, and the translation of the tooth plate will drive the connected L-shaped support slide plate 216 to translate synchronously, which can drive the installed grinding wheel 220 to translate. During the translation process, the grinding wheel 220 will perform a grinding on the surface of the louver blade when it contacts the translation transmission. Flat-sweeping grinding, and in the process of the L-shaped support slide 216 passively moving horizontally on the special-shaped support rod 1 217, it also drives the corresponding meshing assembly 218 installed to engage with each other. The spur gear installed on the L-shaped support slide 216 can rotate when meshing with the U-shaped tooth plate, thereby driving the corresponding grinding wheel 220 through the rotating rod 219 to perform flat-sweeping and rotating grinding, which can significantly improve the processing quality and efficiency, and avoid the regular stripes (such as longitudinal linear stripes or transverse periodic stripes) easily generated by single-direction grinding in the prior art. The rotational motion makes the abrasive cutting tracks cross in a mesh, effectively dispersing the wear marks, and avoiding the problem of uneven surface finish caused by directional texture aggregation;

[0047] The piston 222 is moved back and forth to move the piston 223 and the piston 224 is moved back and forth to move the piston 223. The piston 222 is moved back and forth to move the piston 223 and the piston 224 is moved back and forth to move the piston 223. The piston 222 is moved back and forth to move the piston 223 and the piston 224 is moved back and forth to move the piston 223. Figure 6 As shown, the block 228 installed on the rod body will simultaneously resist the inclined plate 230, driving it to rotate and tilt with the vertical rod installed on the slot connecting plate 229 as the central axis, thereby driving another piston T rod 222 installed with a ball shaft 231 to translate, generating extrusion gas inside the corresponding piston cylinder 223, and at the same time squeezing and the spring 232 installed on the inner wall of the piston cylinder 223. The installation of the spring 232 facilitates the subsequent automatic reset of the piston T rod 222 when it is not under force, thereby achieving the effect of alternating suction of debris powder, so that the operation of collecting louver debris powder can continue.
