Description

Technical Field

[0001] The present invention belongs to the technical field of polishing equipment, and particularly relates to a sheet polishing equipment. Background Art

[0002] A polishing machine, also known as a grinding machine, is commonly used for mechanical grinding, polishing and waxing. At present, many workpiece processing operations use polishing machines, but the following problems exist in the current polishing machines during the processing: 1. When the existing polishing machine is used for product grinding, it can only grind flat wooden boards, but for non-flat plates, such as special-shaped parts [integrally formed wooden benches, tables, etc. with multiple arcs, such as Figure 14 the products shown], precise grinding cannot be carried out. Manual grinding and polishing are required, which are time-consuming and laborious. When more precise polishing is needed, it cannot be achieved, reducing the product quality.

[0003] 2. After the fixed brush roller is worn and impurities such as wood chips and sand grains are attached during long-term use, it will cause mechanical damage. When the workpiece is ground during processing, due to the particulate matter attached to the surface of the fixed brush roller, the surface quality of the processed workpiece will have errors, resulting in defective parts. This increases the processing cost.

[0004] 3. If the rotational speed of the fixed brush roller is too high or the pressure is too large, it will cause overheating and the board will turn black.

[0005] Therefore, in view of the above technical problems, it is necessary to provide a sheet polishing equipment.

Detailed implementation manner

[0024] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0025] As Figure 1 shown, a sheet polishing equipment in an embodiment of the present invention includes a base 1 and a polishing equipment housing 4. The sheet polishing equipment further includes an automatic feeding mechanism 2, a fixture 3, a lifting mechanism 5, a special-shaped part polishing mechanism 6, a multi-effect maintenance mechanism, and a post-cleaning mechanism 8. The polishing process of the workpiece 9 is realized.

[0026] As Figure 1 shown, the automatic feeding mechanism 2 is used to fix the workpiece 9. When the workpiece 9 needs to be processed, the workpiece 9 is inserted vertically into the inner wall end face of the automatic feeding mechanism 2. The automatic feeding mechanism 2 includes a first fixture and a second fixture. A limiting groove is formed between the first fixture and the second fixture. The first fixture is fixed and the second fixture is in a detachable state. The size of the limiting groove between the first fixture and the second fixture can be adjusted according to the thickness of the workpiece 9. The workpiece 9 is clamped in the limiting groove for limiting and fixing. When the workpiece 9 is inserted into the limiting groove, it is in a fixed state and will not move.

[0027] It should be noted that the height of the automatic feeding mechanism 2 is preferably one-third of the end face of the workpiece 9 to be processed. During processing, the upper end face of the workpiece 9 can be processed first. After processing, the other unprocessed end face of the workpiece 9 is taken out, and the processed end face is inserted into the limit groove for fixation. At the same time, the distance between the second fixture is adjusted to stably fix the workpiece 9 between the first fixture and the second fixture.

[0028] Preferably, silicone pads are bonded to the end faces of the first fixture and the second fixture that are in contact with the workpiece 9, which can protect the outer shape of the workpiece 9 to be processed and increase the stability of the workpiece 9 fixed on the automatic feeding mechanism 2.

[0029] The upper end face of the fixture 3 is fixedly connected to the automatic feeding mechanism 2. The fixture 3 drives the automatic feeding mechanism 2 to slide on the base 1 for polishing. The fixture 3 includes a feeding plate 301 and a slide rail mechanism 302. The feeding plate 301 is fixedly connected to the top end face of the slide rail mechanism 302. Preferably, the slide rail mechanism 302 is a lead screw transmission mechanism, that is, it includes a lead screw, a driving motor, and a transmission table. The transmission table is fixed on the lead screw, and the driving motor drives the lead screw to rotate, thereby driving the transmission table to move, and driving the automatic feeding mechanism 2 to move for processing the workpiece 9.

[0030] The automatic feeding mechanism 2 is fixedly connected to the top end face of the feeding plate 301 through bolts. The slide rail mechanism 302 drives the feeding plate 301 to move to polish the workpiece 9.

[0031] The bottom end face of the lifting mechanism 5 is fixedly connected with a special-shaped part polishing mechanism 6. One side end face of the lifting mechanism 5 is fixedly connected to one side end face of the base 1. The lifting mechanism 5 drives the special-shaped part polishing mechanism 6 to move up and down to fit the workpiece 9 for processing and polishing.

[0032] The lifting mechanism 5 includes a connecting seat 501 and a hydraulic cylinder 502. One side end face of the hydraulic cylinder 502 is fixedly connected to the inner wall end face of the polishing equipment housing 4. The bottom end faces of a plurality of hydraulic cylinders 502 are fixedly connected to the connecting seat 501. By driving the connecting seat 501 to move up and down through a plurality of hydraulic cylinders 502, the special-shaped part polishing mechanism 6 is driven to descend to polish the plurality of end faces of the workpiece 9 up and down.

[0033] Such as Figures 3 - 6As shown, the special-shaped part polishing mechanism 6 includes a plurality of first fixed brush rollers 601, a second fixed brush roller 602 and a third fixed brush roller 603. The plurality of first fixed brush rollers 601, the second fixed brush rollers 602 and the third fixed brush rollers 603 are matched and fitted with a plurality of end surfaces of the workpiece 9 to grind the plurality of end surfaces of the workpiece 9. The special-shaped part polishing mechanism 6 is provided with an anti-overheating mechanism to achieve that when the first fixed brush rollers 601, the second fixed brush rollers 602 and the third fixed brush rollers 603 are processing the workpiece 9, under the protection of the anti-overheating mechanism, the first fixed brush rollers 601, the second fixed brush rollers 602 and the third fixed brush rollers 603 are subjected to timely cooling treatment when the temperature is too high, thereby reducing the influence of the high temperature on the first fixed brush rollers 601, the second fixed brush rollers 602 and the third fixed brush rollers 603, and prolonging the service life of the first fixed brush rollers 601, the second fixed brush rollers 602 and the third fixed brush rollers 603.

[0034] Among them, a plurality of first fixed brush rollers 601, second fixed brush rollers 602 and third fixed brush rollers 603 are arranged on the bottom end surface of the lifting mechanism 5 in different regions according to the end surface of the workpiece 9, and the special-shaped part polishing mechanism 6 grinds the multiple end surfaces of the workpiece 9 in different regions in turn. When designing, the positions of the first fixed brush roller 601, the second fixed brush roller 602 and the third fixed brush roller 603 can be designed according to the workpiece to be processed so that they are more in line with the processed end surface of the workpiece 9, and the first fixed brush roller 601, the second fixed brush roller 602 and the third fixed brush roller 603 can be separately designed to grind the workpiece 9 in different regions.

[0035] Furthermore, the plurality of first fixed brush rollers 601, the second fixed brush rollers 602 and the third fixed brush rollers 603 are all connected to a gear set 605, and the plurality of gear sets 605 are respectively connected to a motor set 604, that is, according to design requirements, the plurality of first fixed brush rollers 601, the second fixed brush rollers 602 and the third fixed brush rollers 603 can be selected to be driven by gears and then driven by a motor to drive the gears to drive the plurality of first fixed brush rollers 601, the second fixed brush rollers 602 and the third fixed brush rollers 603 to rotate for grinding work.

[0036] One end surface of the plurality of gear sets 605 is rotatably connected to a rotating shaft, one end surface of the rotating shaft is connected to a rotating base, and one end surface of the rotating base is fixedly connected to the connecting seat 501. That is, the gear drives the rotating shaft to rotate, and the rotating shaft is fixed to the rotating base through a bearing, so that the plurality of gears are fixed to the bottom end surface of the lifting mechanism 5, thereby driving the plurality of first fixed brush rollers 601, the second fixed brush roller 602 and the third fixed brush roller 603 to rotate.

[0037] Preferably, extension columns are fixedly connected between the motor set 604 and the gear set 605 and the connecting seat 501. Through the extension columns, the distances between the first fixed brush roller 601, the second fixed brush roller 602 and the third fixed brush roller 603 and the connecting seat 501 can be controlled to be longer, and the lowest space for the connecting seat 501 to drive the first fixed brush roller 601, the second fixed brush roller 602 and the third fixed brush roller 603 to move downward to polish the workpiece 9 can be better controlled, so as to polish the workpiece 9 in all directions.

[0038] As Figure 5 shown, a plurality of first fixed brush rollers 601 match the transverse end faces of the workpiece 9. The first fixed brush rollers 601 are horizontally arranged on the bottom end face of the connecting seat 501, that is, the transverse straight end faces with longer dimensions of the workpiece 9 can be polished, and when the plurality of first fixed brush rollers 601 are polishing, they can fit the transverse front and rear end faces of the workpiece 9 for processing and polishing. During processing and polishing, the first fixed brush roller 601 can be controlled to descend to the transverse end face of the workpiece 9 and fit to move up and down for polishing.

[0039] As Figure 6 shown, the second fixed brush roller 602 matches the adjacent straight end faces of the workpiece 9 located on a plurality of arc surfaces, that is, a plurality of second fixed brush rollers 602 are respectively arranged on the straight end faces near the arc end faces of the workpiece 9 to process and polish the small-sized plane end faces of the workpiece 9. The second fixed brush roller 602 is horizontally or vertically arranged on the bottom end face of the connecting seat 501.

[0040] As Figure 4 shown, the third fixed brush roller 603 matches the plurality of arc end faces of the workpiece 9. The third fixed brush roller 603 is vertically arranged on the bottom end face of the connecting seat 501, that is, the third fixed brush roller 603 matches the plurality of arc end faces of the inner and outer end faces of the workpiece 9. The third fixed brush roller 603 is arranged on the inner and outer end faces of the workpiece 9 respectively, and the third fixed brush roller 603 adapts to the size of the arc, and can better polish the plurality of arc gaps and the plurality of gaps accurately, and the polishing accuracy is high.

[0041] It should be noted that during processing, polishing and grinding, the workpiece 9 enters the lower end faces of the first fixed brush roller 601, the second fixed brush roller 602 and the third fixed brush roller 603 in sequence for processing and grinding by moving up and down in the vertical direction. During the grinding process, under the fixing action of the automatic feeding mechanism 2 on the workpiece 9, the stability is relatively high, and the workpiece 9 can be processed, polished and ground accurately.

[0042] The multi-effect maintenance mechanism includes an anti-overheating mechanism, a vision sensor, a multi-angle auxiliary polishing mechanism 7 and a dust suction mechanism. When the special-shaped part polishing mechanism 6 is overheated during processing, the anti-overheating mechanism can cool it down. When the special-shaped part polishing mechanism 6 is in a non-working state, the multi-angle auxiliary polishing mechanism 7 can polish it to remove impurities on its surface, extend the service life of the first fixed brush roll 601, the second fixed brush roll 602 and the third fixed brush roll 603, and reduce the cost of later maintenance. The dust suction mechanism adsorbs the dust generated during the processing to prevent it from affecting the processing quality.

[0043] The anti-overheating mechanism includes a temperature sensor, a gas storage tank 12 and a plurality of cooling pipes 6012. The cooling pipes 6012 are connected to the gas storage tank 12 through gas delivery pipes. The plurality of cooling pipes 6012 are respectively arranged on a pair of opposite end faces of the plurality of first fixed brush rolls 601, second fixed brush rolls 602 and third fixed brush rolls 603. The first fixed brush roll 601, the second fixed brush roll 602 and the third fixed brush roll 603 all include a rotating shaft 6013. Heat dissipation holes are formed on a pair of opposite end faces of the rotating shaft 6013. A gas delivery pipe is connected in the heat dissipation holes. The gas delivery pipe penetrates through the rotating shaft 6013. After the rotating shaft 6013 is connected to the gas storage tank 12, when the temperature sensor detects that the temperatures of the first fixed brush roll 601, the second fixed brush roll 602 and the third fixed brush roll 603 are too high, the gas storage tank 12 delivers inert gas into the gas delivery pipe and blows it towards the end faces of the first fixed brush roll 601, the second fixed brush roll 602 and the third fixed brush roll 603 through the plurality of cooling pipes 6012, so as to achieve the effect of cooling them, keep their temperatures at a low level all the time, and prevent the high temperature from affecting the service life of the fixed brush roll and the processing quality of the processed parts.

[0044] Among them, the gas storage tank 12 stores one of nitrogen or argon to achieve the effect of cooling the first fixed brush roll 601, the second fixed brush roll 602 and the third fixed brush roll 603 during operation.

[0045] Furthermore, the cooling pipe 6012 is "L"-shaped, that is, one end face of the cooling pipe 6012 is close to the end faces of the first fixed brush roll 601, the second fixed brush roll 602 and the third fixed brush roll 603 at a short distance, but does not affect the normal operation of the first fixed brush roll 601, the second fixed brush roll 602 and the third fixed brush roll 603. Preferably, the cooling pipe 6012 is located at the central axis end face of the rotating shaft 6013. A plurality of temperature sensors are respectively arranged on one end face of the first fixed brush roll 601, the second fixed brush roll 602 and the third fixed brush roll 603 to monitor their operating temperatures.

[0046] Secondly, during the process of cooling the first fixed brush roll 601, the second fixed brush roll 602, and the third fixed brush roll 603 by the cooling pipe 6012, under the action of the gas, it can also assist in cleaning the impurities attached to the first fixed brush roll 601, the second fixed brush roll 602, and the third fixed brush roll 603, ensuring that the cleanliness of the surfaces of the first fixed brush roll 601, the second fixed brush roll 602, and the third fixed brush roll 603 does not affect the fine grinding of the workpiece 9, and preventing the polishing quality from being affected due to the presence of impurities on the surfaces of the first fixed brush roll 601, the second fixed brush roll 602, and the third fixed brush roll 603.

[0047] The dust collection mechanism includes a dust collection pipe 6011, a waste storage box 11, and a negative pressure vacuum unit 13. A pair of opposite end faces of the rotating shaft 6013 are each provided with air vents. The dust collection pipe 6011 is arranged at the end face of the first fixed brush roll 601 located at the air vents. The dust collection pipe 6011 is connected to a second dust collection pipe. The second dust collection pipe penetrates through the rotating shaft 6013. The second dust collection pipe is connected to the waste storage box 11. The other end face of the waste storage box 11 is connected to the negative pressure vacuum unit 13. The negative pressure vacuum unit 13 is fixedly connected to the top end face of the polishing equipment housing 4.

[0048] It should be noted that the adsorption port of the dust collection pipe 6011 is located on the outer end face of the cooling pipe 6012, and the adsorption end face is facing the end face of the workpiece 9 to be processed, so as to adsorb the dust and prevent the dangerous situation of explosion due to excessive dust.

[0049] Specifically, the negative pressure vacuum unit 13 conveys negative pressure into the second dust collection pipe to the dust collection pipe 6011. The negative pressure is conveyed through the dust collection pipe 6011 to adsorb the dust generated during the operation of the first fixed brush roll 601, the second fixed brush roll 602, and the third fixed brush roll 603. After the waste storage box 11 filters the dust, the dust is stored on the inner wall end face of the waste storage box 11, and the filtered gas is output through the negative pressure vacuum unit 13.

[0050] As Figures 1 - 11 shown, the multi-angle auxiliary polishing mechanism 7 is located at the middle end face of the special-shaped part polishing mechanism 6. The multi-angle auxiliary polishing mechanism 7 includes a multi-angle rotating arm 702 and an auxiliary polishing brush roll 705. The multi-angle rotating arm 702 drives the auxiliary polishing brush roll 705 to move multi-angularly. The visual sensor is arranged at the bottom end face of the multi-angle auxiliary polishing mechanism 7. Through the visual sensor, the processing quality of the workpiece 9 and the conditions of the surfaces of the first fixed brush roll 601, the second fixed brush roll 602, and the third fixed brush roll 603 can be monitored at any time. In case of abnormality, corresponding measures can be taken immediately.

[0051] The multi-angle auxiliary polishing mechanism 7 further includes a bottom plate 701. The top end face of the bottom plate 701 is fixedly connected to the bottom end face of the lifting mechanism 5. A multi-angle rotating arm 702 is fixedly connected to the bottom of the bottom plate 701. The multi-angle rotating arm 702 is connected to a fixed seat 703. A third driving motor 704 is fixedly connected to one side end face of the fixed seat 703. The third driving motor 704 is connected to an auxiliary polishing brush roll 705. Through the telescopic rotation of the multi-angle rotating arm 702, the auxiliary polishing brush roll 705 is driven to move to the bottom end faces of the first fixed brush roll 601, the second fixed brush roll 602, and the third fixed brush roll 603 at the bottom of the lifting mechanism 5 and fit with them. The first fixed brush roll 601, the second fixed brush roll 602, and the third fixed brush roll 603 can be started to rotate and fit with the auxiliary polishing brush roll 705 to friction the surface to remove the attached wood chips or sand grains on the surface, ensuring that there are no defective products in the processed workpieces, prolonging the service life of the fixed brush rolls, reducing the maintenance times of the staff, and improving the processing accuracy of the workpieces 9.

[0052] Preferably, the multi-angle rotating arm 702 includes a driving mechanism, a plurality of rotating shaft sub-arms, and a hydraulic cylinder. A driving motor is connected between the plurality of rotating shaft sub-arms to control the rotation between the plurality of rotating shaft sub-arms. A hydraulic cylinder is connected to one of the rotating shaft sub-arms. A fixed seat 703 is fixedly connected to one side end face of the hydraulic cylinder, so as to drive the auxiliary polishing brush roll 705 to move to the adapted position for grinding work through the telescopic movement of the plurality of rotating shaft sub-arms.

[0053] Specifically, when one of the first fixed brush roll 601, the second fixed brush roll 602, and the third fixed brush roll 603 is damaged, the multi-angle rotating arm 702 can be controlled to drive the auxiliary polishing brush roll 705 to move to its position to replace it for temporary grinding and polishing work. It should be noted that when the corresponding fixed brush roll is damaged, it needs to be disassembled first before the multi-angle auxiliary polishing mechanism 7 can be controlled to replace the damaged fixed brush roll for grinding work.

[0054] When the first fixed brush roll 601, the second fixed brush roll 602, and the third fixed brush roll 603 are used for a long time and it is necessary to remove the attached wood chips or sand grains on their surfaces, the multi-angle rotating arm 702 can be controlled to drive the auxiliary polishing brush roll 705 to sequentially enter the lower side end faces of the corresponding first fixed brush roll 601, second fixed brush roll 602, and third fixed brush roll 603. After fitting them, the first fixed brush roll 601, the second fixed brush roll 602, and the third fixed brush roll 603 are started to rotate and friction on the auxiliary polishing brush roll 705 to remove the impurities on the surface.

[0055] Preferably, the auxiliary polishing brush roll 705 is either a fixed brush roll or a cleaning fixed brush roll 706. During daily use, the cleaning fixed brush roll 706 is selected and installed on the third driving motor 704 for cleaning the special-shaped part polishing mechanism 6. When one of the special-shaped part polishing mechanisms 6 is damaged, the cleaning fixed brush roll 706 is removed from the third driving motor 704, and a new fixed brush roll is replaced for polishing operation.

[0056] As Figure 13 shown, on the outer end face of the cleaning fixed brush roll 706, a plurality of first steel saw teeth 707 are fixedly connected, and the surface of the special-shaped part polishing mechanism 6 is cleaned by the first steel saw teeth 707. The fixed brush roll is a conventional fixed brush roll, having the same structure and material as the first fixed brush roll 601, the second fixed brush roll 602, and the third fixed brush roll 603.

[0057] As Figure 12 shown, of course, it is also possible not to use the multi-angle auxiliary polishing mechanism 7 to clean the impurities attached to the surface of the special-shaped part polishing mechanism 6. A cloth wheel cleaner of the same size as the workpiece 9 can be selected. The cloth wheel cleaner includes a maintenance plate 15, and a plurality of second steel saw teeth 1501 are fixedly connected to the outer end face of the maintenance plate 15. The plurality of second steel saw teeth 1501 can clean the surfaces of the first fixed brush roll 601, the second fixed brush roll 602, and the third fixed brush roll 603. During cleaning, the cloth wheel cleaner can be placed and fixed in the automatic feeding mechanism 2. After fixing, the clamp 3 drives the automatic feeding mechanism 2 to move, thereby driving the cloth wheel cleaner to move to the corresponding end faces of the first fixed brush roll 601, the second fixed brush roll 602, and the third fixed brush roll 603. The first fixed brush roll 601, the second fixed brush roll 602, and the third fixed brush roll 603 rotate to perform friction cleaning on the surface of the cloth wheel cleaner.

[0058] As Figure 5 shown, the post-cleaning mechanism 8 is located on one end face of the base 1. The post-cleaning mechanism 8 includes a cleaning component, a drying component, and a moving component. The cleaning component, the drying component, and the moving component can adapt to multiple end faces of the workpiece 9, and the moving component drives the cleaning component and the drying component to move up and down. The processed workpiece 9 is cleaned to remove the residual wax on its surface.

[0059] The cleaning assembly includes a material storage box group 10, a second scrubbing cotton 808, a third scrubbing cotton 809, and a first scrubbing cotton 803. The post-cleaning mechanism 8 includes a third cleaning plate 806, a second cleaning plate 804, and a first cleaning plate 801. The third cleaning plate 806, the second cleaning plate 804, and the first cleaning plate 801 are fixed to the bottom end face of the connecting seat 501. A second scrubbing cotton 808 is provided at the bottom of the third cleaning plate 806, a third scrubbing cotton 809 is provided at the bottom of the second cleaning plate 804, and a first scrubbing cotton 803 is provided at the bottom of the first cleaning plate 801. The third cleaning plate 806, the second cleaning plate 804, and the first cleaning plate 801 respectively match the two side end faces and the middle end face of the workpiece 9. The first scrubbing cotton 803 is in an "L" shape.

[0060] Cleaning holes are provided on multiple end faces of the second scrubbing cotton 808, the third scrubbing cotton 809, and the first scrubbing cotton 803. The cleaning holes are connected to the material storage box group 10 through cleaning pipes.

[0061] The surface of the workpiece 9 is cleaned of wax residue by spraying wood wax oil cleaner through the cleaning holes of the second scrubbing cotton 808, the third scrubbing cotton 809, and the first scrubbing cotton 803. The material storage box group 10 stores wood wax oil cleaner.

[0062] The drying assembly includes a heat guiding pipe, a negative pressure pump 14, and a heat conducting pipe 6014. Heat conducting pipes 6014 are provided on one side end face of the first fixed brush roller 601, the second fixed brush roller 602, and the third fixed brush roller 603. The heat conducting pipes 6014 are adjacent to the end face of the first fixed brush roller 601. One side end face of the heat guiding pipe is connected to the negative pressure pump 14. The other side end face of the negative pressure pump 14 is connected to the heat conducting pipe 6014. Multiple heat conducting pipes are connected to the second scrubbing cotton 808, the third scrubbing cotton 809, and the first scrubbing cotton 803. Specifically, the negative pressure pump 14 conveys negative pressure into the heat conducting pipe 6014 to output negative pressure to absorb the heat generated during the operation of the first fixed brush roller 601. Then, the negative pressure pump 14 changes the recovered heat into hot air and conveys it into the heat guiding pipe to the second scrubbing cotton 808, the third scrubbing cotton 809, and the first scrubbing cotton 803 to spray and preheat the wax on the surface of the workpiece 9, and then starts to spray wood wax oil cleaner to clean the wax on the surface of the workpiece 9. Realize the recycling of heat, energy saving and environmental protection.

[0063] Further, the moving assembly includes a third lifting mechanism 807, a second lifting mechanism 805, and a first lifting mechanism 802. The third lifting mechanism 807, the second lifting mechanism 805, and the first lifting mechanism 802 are respectively connected to a second scrubbing cotton 808, a third scrubbing cotton 809, and a first scrubbing cotton 803. The third lifting mechanism 807, the second lifting mechanism 805, and the first lifting mechanism 802 are automatic telescopic rods. When cleaning the workpiece 9, the third lifting mechanism 807, the second lifting mechanism 805, and the first lifting mechanism 802 control the third cleaning plate 806, the second cleaning plate 804, and the first cleaning plate 801 to move up and down to clean or dry the inner and outer end faces of the workpiece 9.

[0064] Among them, the shapes of the second scrubbing cotton 808, the third scrubbing cotton 809, and the first scrubbing cotton 803 connected to the bottom end faces of the third lifting mechanism 807, the second lifting mechanism 805, and the first lifting mechanism 802 respectively match the end faces of the workpiece 9 they are attached to, so that they can completely fit the inner side to wrap the corresponding position of the workpiece 9 during scrubbing for covering cleaning.

[0065] A thermal imaging sensor is installed on one end face of the first cleaning plate 801 to detect whether there is wax residue on the surface of the workpiece 9. If there is wax residue, the post-cleaning mechanism 8 can be started for cleaning. The thermal conductivity and specific heat capacity of wax are different from those of wood, and the difference in surface temperature distribution after heating can be captured by an infrared camera. Therefore, a thermal imaging sensor can be used for capture.

[0066] During use, as Figure 2 shown, first insert the workpiece 9 to be polished vertically into the automatic feeding mechanism 2 for fixation, and then start to control the automatic feeding mechanism 2 to move to the position as Figure 5 shown by the hydraulic cylinder 502 controlling the connecting seat 501 to move down to polish and grind the long-distance straight inner and outer end faces of the workpiece 9 through the first fixed brush roller 601. After the grinding is completed, then control the automatic feeding mechanism 2 to move to the position as Figure 6 shown, the connecting seat 501 moves up and down to drive the second fixed brush roller 602 to polish and grind the adjacent straight end faces of the multiple arc surfaces of the workpiece 9. After the grinding is completed, then control the automatic feeding mechanism 2 to drive the workpiece 9 to move to the position as Figure 4 shown, and polish and grind the multiple arc end faces of the workpiece 9 through the third fixed brush roller 603. After the grinding is completed, start the next step; As Figure 8As shown, after the workpiece 9 is polished, when the thermal imaging sensor installed on the post-cleaning mechanism 8 detects the residual wax on the surface of the workpiece 9, the post-cleaning mechanism 8 can be started to clean the workpiece 9. The residual wax on the surface of the workpiece 9 can be removed. The automatic feeding mechanism 2 drives the workpiece 9 to move to the lower side position of the post-cleaning mechanism 8. At this time, the first lifting mechanism 802, the second lifting mechanism 805 and the third lifting mechanism 807 are controlled to drive the first scrubbing cotton 803, the third scrubbing cotton 809 and the second scrubbing cotton 808 to move up and down in contact with multiple end faces of the workpiece 9. First, the heat absorbed by the heat conduction tube 6014 is ejected through the cleaning holes to the surface of the workpiece 9 for preheating, and then the cleaning holes are controlled to spray the wood wax oil cleaner to clean the wax on the surface of the workpiece 9. After the spraying is completed, the second scrubbing cotton 808, the third scrubbing cotton 809 and the first scrubbing cotton 803 are controlled to perform a fitting scrub on the wood surface to wipe off the wax on its surface.
