DETAILED DESCRIPTION

[0069] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0070] Combine the following Figures 1 to 11 As shown, an embodiment of the present invention provides an automatic sanding device for double-sided cabinet panels, comprising:

[0071] Two sanding components, two sanding components are set up in mirror image up and down;

[0072] A supporting assembly, the supporting assembly is connected to the two sanding assemblies, and the supporting assembly is used to support and adjust the distance between the two sanding assemblies;

[0073] Among them, the sanding components include:

[0074] A fixed frame 201, the fixed frame 201 is connected to the supporting assembly, two guide rails 202 are fixed in the fixed frame 201, conveying assemblies are arranged on both sides of the top of the fixed frame 201, and the two guide rails 202 are located between the two conveying assemblies, and two tensioning assemblies are slidably arranged on the two guide rails 202;

[0075] The support plate 306 is fixed to the two guide rails 202. A lifting assembly is disposed on the top of the support plate 306. A door frame 310 is disposed on the top of the lifting assembly. A power roller 206 (such as Figure 6 As shown), shafts 603 are fixed to both side walls of the portal frame 310;

[0076] Two limiting components, both of which are arranged on the top of the support plate 306, and the two limiting components are respectively connected to the two tensioning components, and the limiting components are used to fix the distance between the two tensioning components;

[0077] The tensioning assembly includes:

[0078] Two sliders 203, the two sliders 203 are slidably disposed on the two guide rails 202, and a tensioning roller 205 is rotatably disposed between the two sliders 203;

[0079] Two transmission assemblies, the two transmission assemblies are rotatably disposed on the side walls of the two sliders 203, and the two transmission assemblies are rotatably connected to the two shafts 603;

[0080] A heat dissipation component, which is connected to the two transmission components and is used to cool the sanding component;

[0081] The sanding kit also includes:

[0082] The sanding belt 204 is sleeved on a power roller 206 and two tensioning rollers 205 , and the sanding belt 204 passes through two heat dissipation components.

[0083] The height of the portal frame 310 is adjusted by the operation of the lifting assembly. In this process, the position of the slider 203 is adjusted by the shaft 603 and the transmission assembly, and then the distance between the two tensioning assemblies is adjusted to change the length of the sanding belt 204 between the two tensioning assemblies, thereby achieving a change in the contact area between the sanding belt 204 and the plate. By changing the contact area between the sanding belt 204 and the plate, the sanding effect can be adjusted while maintaining the plate transportation speed, thereby avoiding the problem of reduced sanding speed due to high-standard sanding.

[0084] Furthermore, the support assembly includes:

[0085] The frame 101 has two-way cylinders 102 disposed on both sides of the top of the frame 101 . The top and bottom telescopic ends of the two two-way cylinders 102 are fixed to the upper fixing frame 201 and the lower fixing frame 201 respectively.

[0086] Further, the conveying assembly includes:

[0087] Two connection holes, both of which are opened on the top of the fixing frame 201, and a rod body 501 is slidably arranged in each connection hole;

[0088] Two first springs 502, both of which are fixed on the top of the fixing frame 201, and the two first springs 502 are fixed to the two rods 501 respectively;

[0089] A conveying roller 503, which is rotatably disposed between the two rod bodies 501;

[0090] The second motor 504 is fixed on one of the rods 501 , and the output shaft of the second motor 504 is fixed to the conveying roller 503 .

[0091] By stretching the first spring 502, the conveying rollers 503 of the two sanding assemblies can still adjust the spacing between the sanding belts 204 on the two sanding assemblies after they collide with each other. In addition, the pulling force provided by the first spring 502 in the stretched state makes the two conveying rollers 503 tend to move towards each other, thereby ensuring the pressure between the conveying rollers 503 and the plate, so as to ensure the normal transportation of the plate during the sanding process.

[0092] Furthermore, the lifting assembly includes:

[0093] A hydraulic push rod 309, the hydraulic push rod 309 is fixed on the top of the support plate 306, and the telescopic end of the hydraulic push rod 309 is fixed to the portal frame 310;

[0094] Two telescopic rods 311 , both of which are fixed on the top of the support plate 306 , and the telescopic ends of the two telescopic rods 311 are fixed to the portal frame 310 .

[0095] Furthermore, the transmission assembly includes:

[0096] A connecting seat 604, which is rotatably sleeved on the shaft 603;

[0097] A connecting sleeve 601, the connecting sleeve 601 is fixed to the end of the connecting seat 604;

[0098] The connecting rod 602 is slidably disposed in the connecting sleeve 601 , a second spring 605 is fixed to the end of the connecting rod 602 , and the second spring 605 is fixed to the inner wall of the connecting sleeve 601 , and the connecting rod 602 is rotatably connected to the slider 203 .

[0099] When the hydraulic push rod 309 works, the height of the portal frame 310 is changed, and then the slider 203 is driven to move on the guide rail 202 through the shaft 603, the connecting sleeve 601, the second spring 605 and the connecting rod 602;

[0100] The thrust provided by the second spring 605 in the compressed state causes the two sliders 203 on the same guide rail 202 to move away from each other, and the sanding belt 204 is always in a tensioned state through the two tensioning rollers 205 to ensure the sanding work is carried out.

[0101] Furthermore, the heat dissipation component includes:

[0102] The cover body 401 is fixed to two connecting sleeves 601 on the same side of the portal frame 310, and the sanding belt 204 passes through the cover body 401;

[0103] An air pump box 402, the air pump box 402 is fixed on the cover body 401, and an air pump is arranged in the air pump box 402;

[0104] Two first communication seats 404, the two first communication seats 404 are respectively fixed on the two side walls of the cover body 401, and the two first communication seats 404 are located on both sides of the sanding belt 204, and each side wall of the first communication seat 404 is fixedly connected and provided with a plurality of air nozzles 405, and each air nozzle 405 penetrates the cover body 401;

[0105] The first three-way pipe 403 has two ends connected to the two first connecting seats 404 respectively, and the other end of the first three-way pipe 403 is connected to the output port of the air pump.

[0106] Furthermore, the sanding assembly also includes:

[0107] Two second connecting seats 406, the two second connecting seats 406 are fixed on two side walls of one of the cover bodies 401, and the two second connecting seats 406 are located on both sides of the sanding belt 204, and each side wall of the second connecting seat 406 is fixedly connected and provided with a plurality of atomizing nozzles 407, and each atomizing nozzle 407 penetrates the cover body 401;

[0108] The second three-way pipe 408 has two ends connected to the two second connecting seats 406 respectively, and the other end of the second three-way pipe 408 is used to connect to the water supply equipment.

[0109] Furthermore, the sanding assembly also includes:

[0110] A first motor 208, the first motor 208 is fixed on the side wall of the door frame 310;

[0111] Two transmission wheels, both of which are rotatably arranged on the side wall of the portal frame 310, one of which is fixed to the output shaft of the first motor 208, and the other is fixed to the power roller 206;

[0112] The transmission belt 207 is sleeved on two transmission wheels.

[0113] During the sanding process, the sanding components operate as follows:

[0114] The switches of the two air pumps are turned on. When the two air pumps are working, the gas is pumped into the two first connecting seats 404 through the first three-way pipe 403, and finally output through the multiple air nozzles 405. Then one end of the second three-way pipe 408 is connected to the water supply device. When the water supply device is working, the water is pumped into the two second connecting seats 406 through the second three-way pipe 408, and then output through the atomizing nozzle 407. Therefore, during the movement of the sand belt 204, the gas output by the two groups of air nozzles 405 on one of the cover bodies 401 first purges the surface and back of the sand belt 204 to prevent dust from adhering to the sand belt 204, and then the water mist output by the atomizing nozzle 407 cools the surface and back of the sand belt 204. Finally, the gas output by the two groups of air nozzles 405 on the other cover body 401 accelerates the evaporation of water on the surface of the sand belt 204, ensures that the sand belt 204 is dry, and further increases the heat dissipation effect, so that the sand belt 204 can work for a long time under the premise of ensuring the sanding quality;

[0115] The upper and lower sanding components work synchronously to perform double-sided sanding on the plate.

[0116] Further, restricted components include:

[0117] Oil storage box 305 (such as Figure 4 As shown), the oil storage box 305 is fixed on the top of the support plate 306;

[0118] Two connecting pipes 304, both connecting pipes 304 are connected to the oil storage box 305;

[0119] A first fixing plate 302, the first fixing plate 302 is fixed on the top of the guide rail 202, sleeves 301 are fixed on both sides of the first fixing plate 302, solenoid valves 303 are penetrated through the side walls of the two sleeves 301, and the two solenoid valves 303 are respectively connected to two connecting pipes 304, and pistons 312 are slidably arranged in the two sleeves 301;

[0120] Two sleeve rods 307 (such as Figure 8 As shown), the two sleeve rods 307 are respectively fixed to the two pistons 312;

[0121] The two second fixing plates 308 are respectively fixed to the ends of the two sleeve rods 307 , and the two second fixing plates 308 are respectively fixed to the two sliding blocks 203 on the same guide rail 202 .

[0122] During the movement of the two sliders 203 on the same guide rail 202, the switch of the solenoid valve 303 is turned on, so that the hydraulic oil in the oil storage box 305 can enter the sleeve 301 or enter the oil storage box 305 from the sleeve 301, so that the two sliders 203 can move freely;

[0123] When the position adjustment of the slider 203 is completed, the switch of the solenoid valve 303 is closed, so that the space enclosed by the sleeve 301 and the piston 312 is sealed, so that the positions of the sleeve 301 and the piston 312 are fixed, and the first fixed plate 302, the second fixed plate 308 and the sleeve rod 307 are cooperated to fix the two sliders 203 on the same guide rail 202 and the guide rail 202 to ensure the stability of the sanding belt 204 during the sanding process.

[0124] The specific working method is: when performing the plate sanding work, first determine the distance between the two sanding components according to the thickness of the plate, and then adjust the distance between the two fixed frames 201 through the operation of the two bidirectional cylinders 102, thereby driving the two sanding components to move closer or farther from each other, so as to adjust the distance between the two sanding belts 204;

[0125] Then, the shaft body 603 and the power roller 206 are coaxially tested, that is, the axis center line of the shaft body 603 and the axis center line of the power roller 206 need to be coincident, and then it is ensured that the connecting seat 604 can rotate around the axis center line of the shaft body 603, and finally it is ensured that the connecting rod 602 can rotate around the axis center line of the tensioning roller 205, thereby achieving that no matter how the height of the portal frame 310 is adjusted, the connecting sleeve 601 always keeps parallel to the sand belt 204 between the power roller 206 and the tensioning roller 205, so that during or after the adjustment, the sand belt 204 does not contact the cover body 401, so as to avoid the cover body 401 causing obstruction to the sand belt 204;

[0126] After the spacing adjustment work is completed, according to the sanding requirements, the spacing of the two tensioning rollers 205 is adjusted, that is, the contact area between the sanding belt 204 and the plate is adjusted. When adjusting the spacing of the tensioning rollers 205, first turn on the switches of the hydraulic push rod 309 and the electromagnetic valve 303. Since the electromagnetic valve 303 is turned on, the sleeve 301 and the oil storage box 305 are connected through the electromagnetic valve 303 and the connecting pipe 304. At this time, the piston 312 can slide along the sleeve 301, so that the slider 203 can move on the guide rail 202. When the hydraulic push rod 309 works, it drives the portal frame 310 to rise or fall. In the process of the portal frame 310 rising and falling, the slider 203 is driven along the guide rail 202 through the shaft body 603, the connecting seat 604, the connecting sleeve 601, the second spring 605 and the connecting rod 602. 02 sliding, in this process, the elastic force provided by the second spring 605 makes the two sliders 203 on the same guide rail 202 always in a movement trend away from each other, and then the abrasive belt 204 can always be kept in a tensioned state through the tensioning roller 205. During the movement of the two sliders 203, after the adjustment is completed, the switches of the hydraulic push rod 309 and the solenoid valve 303 are turned off. After the hydraulic push rod 309 stops working, the height of the door frame 310 remains fixed. After the solenoid valve 303 is closed, the space enclosed by the sleeve 301 and the piston 312 is sealed, that is, the hydraulic oil cannot enter or output from the sleeve 301, that is, the sleeve 301, the piston 312 and the sleeve rod 307 remain fixed, and cooperate with the fixation of the first fixed plate 302 to fix the positions of the two sliders 203;

[0127] After both upper and lower sanding assemblies are adjusted, the switches of the two first motors 208 can be turned on. When the first motors 208 are working, the power roller 206 is driven to rotate through the transmission wheel and the transmission belt 207 to drive the sanding belt 204 to rotate. The rotation direction of the sanding belt 204 is as follows: Fig.11 As shown, the plate is placed at the two sanding assemblies, and finally the switch of the second motor 504 is turned on;

[0128] When the two second motors 504 in the upper sanding assembly are working, the two conveying rollers 503 are driven to rotate in the same direction. When the two second motors 504 in the lower sanding assembly are working, the two conveying rollers 503 are driven to rotate in the same direction. The upper conveying roller 503 and the lower conveying roller 503 rotate in opposite directions to realize the transportation of the plate.

[0129] During the transportation of the plate, the tension provided by the first spring 502 causes the upper and lower conveying rollers 503 to tend to approach each other, thereby ensuring the pressure between the conveying rollers 503 and the plate. Since the first spring 502 can be stretched, there is no need to adjust the distance between the upper and lower conveying rollers 503 during the adjustment of the distance between the sanding belts 204.

[0130] During the sanding process, the sanding components operate as follows:

[0131] Turn on the switches of the two air pumps. When the two air pumps are working, the gas is pumped into the two first connecting seats 404 through the first three-way pipe 403, and finally output through multiple air nozzles 405. Then one end of the second three-way pipe 408 is connected to a water supply device (such as a water pump, etc.). When the water supply device is working, water is pumped into the two second connecting seats 406 through the second three-way pipe 408, and then output through the atomizing nozzle 407. Therefore, during the movement of the sanding belt 204, the gas output by the two groups of air nozzles 405 on one of the cover bodies 401 first purges the surface and back of the sanding belt 204 to prevent dust from adhering to the sanding belt 204, and then the water mist output by the atomizing nozzle 407 cools the surface and back of the sanding belt 204. Finally, the gas output by the two groups of air nozzles 405 on the other cover body 401 accelerates the evaporation of water on the surface of the sanding belt 204, ensures that the sanding belt 204 is dry, and further increases the heat dissipation effect, so that the sanding belt 204 can work for a long time while ensuring the sanding quality.

[0132] It is worth noting that during use of the device, a tensioning plate or a tensioning wheel should be selected according to the actual sanding conditions to increase the wrap angle of the sanding belt 204 and the power roller 206 to ensure that the sanding belt 204 can work normally. In addition, the bidirectional cylinder 102, the first motor 208, the second motor 504, the solenoid valve 303, the hydraulic push rod 309, and the air pump mentioned in the present invention can all be automatically controlled by a single-chip microcomputer. The automation circuit is relatively simple and belongs to a mature prior art, and the present invention will not go into details.

[0133] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
