Description

TECHNICAL FIELD

[0002] A color sorting machine is a device that uses photoelectric detection technology to automatically separate different colored particles in granular materials according to the differences in their optical properties. Currently, color sorting machines are used in the fields of bulk material or packaged industrial products, food quality detection and grading. The color sorting machine is internally provided with a channel, on which a probe head and a light supplement lamp are sequentially installed, as well as a material blowing machine. When the color sorting machine is fed through the material falling port, the screened material will slide along the landslide at the bottom of the material falling port to the position in contact with the channel, and then the probe head starts to work. The probe head starts to work under the irradiation of the light supplement lamp and transmits the captured photos to the computer. Then the computer gives instructions to the material blowing machine to blow different colored materials into different channels, thus completing the screening work.

[0003] However, due to the different materials or the problem of working time, because the color sorting machine can screen many kinds of materials, including some corrosive materials and relatively hard materials. Generally, the channel of the color sorting machine is sprayed with reflective paint to cooperate with the light supplement lamp to make the inside of the machine bright, which is convenient for the probe head to capture information. When screening corrosive materials, the reflective paint will slowly react and be removed with the length of work, and the hard material will repeatedly scratch the surface of the paint, making the internal light supplement effect of the machine poor, and the corrosive material slowly reacts with the paint, affecting the purity of the raw material. These factors make the probe head unable to accurately detect, and the screening effect cannot reach the accurate value. Therefore, the surface of the channel needs to be repaired, so the channel surface repairing device for the color sorting machine is needed. SUMMARY

When the chute 21 is damaged and needs to be repaired, the chute 21 is controlled to rise in the rectangular cylinder 2, so that the chute 21 contacts the grinding disc 57 at the lower part of the mounting block 5. Then the driving part is started to control the mounting block 5 to reciprocate, and the grinding disc 57 rotates at the same time. At this time, the mounting block 5 drives the grinding disc 57 to grind the chute 21, so that the chute 21 is ground flat, which is convenient for the flatness of the chute 21 after painting in the later period.

[0035] Referring to Figures 3-6 The driving part includes a screw rod 23, two symmetrically arranged mounting seats 22 are fixedly connected to the outer wall of the rectangular cylinder 2, the screw rod 23 is rotatably connected to the mounting seat 22, a rectangular block 501 is fixedly connected to the side wall of the mounting block 5, the rectangular block 501 is threadedly connected to the screw rod 23, a motor 24 is fixedly connected to the outer wall of the screening bin 3, the output end of the motor 24 is fixedly connected with a driving shaft 25, the end of the driving shaft 25 is fixedly connected with a first bevel gear 26, a sliding rod 42 is slidably connected to one end of the screw rod 23 close to the screening bin 3, a mounting column 27 is fixedly connected to the middle part of the sliding rod 42, a second bevel gear 28 and a third bevel gear 29 are symmetrically fixedly connected to the two ends of the mounting column 27, a limiting protrusion 43 is arranged on the side wall of the sliding rod 42, and a sliding groove is formed in the screw rod 23 and matched with the limiting protrusion 43.

[0036] The motor 24 is started to rotate the driving shaft 25, and the first bevel gear 26 on the driving shaft 25 rotates. In the initial state, the first bevel gear 26 is engaged with the second bevel gear 28, and the second bevel gear 28 drives the sliding rod 42 to rotate synchronously. The limiting protrusion 43 on the sliding rod 42 slides in the screw rod 23, so that the sliding rod 42 can drive the screw rod 23 to rotate. At this time, the rotating screw rod 23 can drive the rectangular block 501 to move axially on the screw rod 23, so that the mounting block 5 fixedly connected with the rectangular block 501 can move synchronously with the rectangular block 501. The arrangement of the mounting column 27 can improve the overall mechanical strength of the sliding rod 42, so that the service life of the sliding rod 42 is improved when the screw rod 23 is rotated by the sliding rod 42.

[0037] Referring to Figure 3 and Figure 4 , the side wall of the screening bin 3 is fixedly connected with a first electric telescopic rod 4, the output end of the first electric telescopic rod 4 is fixedly connected with a rotating ring 41, the rotating ring 41 is rotationally connected with a sliding rod 42, the opposite faces of the two mounting seats 22 are respectively provided with a first pressure sensitive switch 44 and a second pressure sensitive switch 45 for controlling the first electric telescopic rod 4, and the rectangular block 501 alternately abuts against the first pressure sensitive switch 44 and the second pressure sensitive switch 45.

[0038] When the rectangular block 501 moves to the lower mounting seat 22, it can contact the second pressure sensitive switch 45, at this time, the second pressure sensitive switch 45 controls the first electric telescopic rod 4 to elongate, and then the sliding rod 42 is pushed to slide into the screw rod 23, at this time, the third bevel gear 29 meshes with the first bevel gear 26, and then the turning direction of the screw rod 23 is adjusted, at this time, the screw rod 23 drives the rectangular block 501 to slide to the upper mounting seat 22, when the rectangular block 501 contacts the upper first pressure sensitive switch 44, the first electric telescopic rod 4 is shortened, and then the second bevel gear 28 meshes with the first bevel gear 26 again, at this time, the turning direction of the screw rod 23 is adjusted again, so that the rectangular block 501 slides to the lower mounting seat 22, and the installation block 5 can reciprocate in the rectangular cylinder 2, the output end of the first electric telescopic rod 4 is rotationally connected with the sliding rod 42 through the rotating ring 41, so that the arrangement of the first electric telescopic rod 4 does not interfere with the rotation of the screw rod 23.

[0039] Referring to Figure 2 , Figure 5 , Figure 6 and Figure 7 , the driving part further comprises a rack 201 fixedly connected to the rectangular cylinder 2 at the opposite side of the screw rod 23, the end of the installation block 5 away from the rectangular block 501 is fixedly connected with a rotating seat 502, the rotating seat 502 is rotationally connected with a transmission tooth 202 meshing with the rack 201, the installation block 5 is rotationally connected with a rotating shaft 52, the end of the rotating shaft 52 close to the transmission tooth 202 is fixedly connected with an acceleration tooth 53 meshing with the transmission tooth 202, the middle part of the rotating shaft 52 is fixedly connected with a plurality of fifth bevel gears 54, the upper part of a plurality of polishing discs 57 is fixedly connected with a mounting rod 56, the top of the plurality of mounting rods 56 is fixedly connected with a fourth bevel gear 55, and the plurality of fourth bevel gears 55 respectively correspondingly mesh with the plurality of fifth bevel gears 54 close to them.

[0040] When the mounting block 5 reciprocatingly slides in the rectangular cylinder 2, the rotating seat 502 on the mounting block 5 moves synchronously with the mounting block 5, at this time the rotating seat 502 drives the transmission teeth 202 to roll on the rack 201, and then the rack 201 drives the acceleration teeth 53 to rotate, at this time the acceleration teeth 53 drive the rotating shaft 52 to rotate, since the diameter of the transmission teeth 202 is much larger than that of the acceleration teeth 53, and then the rotating speed of the acceleration teeth 53 is faster, at this time the rotating speed of the rotating shaft 52 is faster, and then the rotating speed of the fifth bevel gear 54 on the rotating shaft 52 is faster, and then the fifth bevel gear 54 can drive the fourth bevel gear 55 to rotate fast, and then the mounting rod 56 rotates fast, and then the mounting rod 56 drives the polishing disc 57 to rotate fast, at this time the fast rotating polishing disc 57 can polish the slide 21, so that the surface of the slide 21 is flat, and in actual use, the number of the polishing discs 57 can be increased or decreased according to the width of the slide 21, so that the polishing disc 57 can cover the width of the slide 21.

[0041] Embodiment Two

[0042] With reference to Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 8 and Figure 9 , on the basis of Embodiment One, further, two mounting racks 6 are symmetrically and fixedly connected on the two side surfaces of the mounting block 5, two scraping blocks 61 are fixedly connected in the two mounting racks 6, straight telescopic rods 62 are fixedly connected between the scraping blocks 61 and the mounting racks 6, springs 63 are sleeved on the straight telescopic rods 62, the two ends of the springs 63 are fixedly connected with the mounting racks 6 and the scraping blocks 61 respectively, and the distance between the mounting rack 6 and the slide 21 is greater than the distance between the polishing disc 57 and the slide 21.

[0043] When the slide 21 moves upwards, the upper surface of the slide 21 first contacts the scraping block 61, at this time the slide 21 that continues to move upwards exerts a pushing force on the scraping block 61, at this time the scraping block 61 slides upwards relative to the mounting rack 6, and then the straight telescopic rod 62 shortens, the straight telescopic rod 62 is arranged to connect the scraping block 61 and the mounting rack 6, when the straight telescopic rod 62 shortens, the spring 63 is compressed synchronously, at this time the contact force between the scraping block 61 and the slide 21 is greater, and then the scraping block 61 can generate a greater friction force when it slides relative to the slide 21, so that the surface of the slide 21 is wiped by the scraping block 61, avoiding the influence of the residues on the slide 21 on the polishing of the polishing disc 57, since the distance between the mounting rack 6 and the slide 21 is greater than the distance between the polishing disc 57 and the slide 21, the slide 21 can first contact the scraping block 61 when it moves upwards, and meanwhile, the mounting rack 6 avoids interfering with the contact between the polishing disc 57 and the slide 21.

[0044] With reference to Figure 1 , Figure 2 , Figure 3 , Figure 5 ,Figure 8 and Figure 9 The middle of the rotating shaft 52 is fixedly connected with a plurality of impellers 59, a plurality of mounting barrels 58 are fixedly connected in the mounting block 5, the plurality of impellers 59 are rotationally connected in the plurality of mounting barrels 58 one by one, two dust suction pipes 582 are symmetrically fixedly connected on the two sides of the mounting barrel 58, the ends of the two dust suction pipes 582 away from the mounting barrel 58 both penetrate the mounting frame 6 and extend to the vicinity of the polishing disc 57, and the top of the mounting barrel 58 is fixedly connected with a dust outlet pipe 581. The top of the mounting block 5 is fixedly connected with a dust storage box 51, and the dust outlet pipe 581 communicates with the dust storage box 51.

[0045] When the rotating shaft 52 rotates, the impeller 59 fixedly connected with the rotating shaft 52 rotates synchronously. Since the impeller 59 rotates in the mounting barrel 58, the negative pressure can be generated at the dust suction pipe 582 when the impeller 59 rotates in the mounting barrel 58. At this time, the floating matter generated when the polishing disc 57 is polished is absorbed by the dust suction pipe 582, and the floating matter absorbed by the dust suction pipe 582 can enter the dust storage box 51 through the dust outlet pipe 581 and be stored. Meanwhile, the mounting frame 6 and the scraping block 61 are arranged, so that the space where the polishing disc 57 is located is relatively closed, thereby avoiding the floating matter generated when the polishing disc 57 polishes the slide 21 from leaking out.

[0046] Referring to Figure 2 , Figure 10 and Figure 11 The two sides of the rotating shaft 52 are symmetrically fixedly connected with two supports 71, the two supports 71 are fixedly connected with a piston barrel 7, the piston barrel 7 is limitingly and slidably connected with a piston plate 72, one side of the piston plate 72 close to the rotating shaft 52 is fixedly connected with a cylinder 73, the accelerating tooth 53 is coaxially fixedly connected with a cylindrical cam 75, the cylindrical cam 75 is slidably connected in the cylinder 73, the cylinder 73 is provided with a protrusion 74, and the protrusion 74 is slidably connected in the sliding groove on the cylindrical cam 75.

[0047] The arrangement of the support 71 enables the piston barrel 7 to be mounted, and enables the mounting block 5 to drive the piston barrel 7 to move synchronously. When the mounting block 5 moves, the accelerating tooth 53 rotates synchronously, and the cylindrical cam 75 fixedly connected with the accelerating tooth 53 rotates synchronously. Since the piston plate 72 is limitingly and slidably connected in the piston barrel 7, the piston plate 72 does not rotate relative to the piston barrel 7, and the cylinder 73 does not rotate relative to the piston barrel 7, and the cylindrical cam 75 rotates relative to the cylinder 73. At this time, the protrusion 74 in the cylinder 73 slides relative to the sliding groove on the cylindrical cam 75, and the cylinder 73 drives the piston plate 72 to reciprocatingly slide in the piston barrel 7, so that the pressure in the piston barrel 7 alternately changes between positive pressure and negative pressure.

[0048] Referring to Figure 2 , Figure 10 and Figure 11The piston cylinder 7 is fixedly connected with an air inlet pipe 77 and an air outlet pipe 76, the air inlet pipe 77 and the air outlet pipe 76 are both provided with a one-way valve 78, the air outlet pipe 76 is provided with a paint tank 79 at an end away from the piston cylinder 7, the paint tank 79 is provided with a paint spraying pipe 641, a first mounting pipe 64 is fixedly connected in the mounting frame 6 close to the screening bin 3, the paint spraying pipe 641 is mounted on the first mounting pipe 64, a plurality of first shunt pipes 65 are fixedly connected to the middle part of the first mounting pipe 64, the first mounting pipe 64 is provided with an electromagnetic valve 66 at an end close to the paint spraying pipe 641, the side wall of the rectangular cylinder 2 is provided with a third pressure sensitive switch 661 for controlling the opening of the electromagnetic valve 66 and a fourth pressure sensitive switch 662 for controlling the closing of the electromagnetic valve 66, the rotating seat 502 alternately abuts against the third pressure sensitive switch 661 and the fourth pressure sensitive switch 662.

[0049] Since the air inlet pipe 77 and the air outlet pipe 76 are both provided with a one-way valve 78, when the pressure in the piston cylinder 7 changes, external air can be drawn into the piston cylinder 7 through the air inlet pipe 77, and the drawn air can be discharged into the paint tank 79 through the air outlet pipe 76, so that when the polishing disc 57 is driven by the mounting block 5 to polish the slide 21, the paint tank 79 can be pressurized at the same time, when the mounting block 5 moves to the lower part, the rotating seat 502 presses the third pressure sensitive switch 661 at the lower part, and the electromagnetic valve 66 controlled by the third pressure sensitive switch 661 is opened, when the electromagnetic valve 66 is opened, the mounting block 5 starts to move upwards, in this process, the paint in the paint tank 79 is sprayed onto the slide 21 after passing through the paint spraying pipe 641, the first mounting pipe 64 and the first shunt pipe 65 in turn, and the slide 21 is painted and repaired, when the mounting block 5 moves upwards, the piston cylinder 7 still pressurizes the paint tank 79, ensuring that the paint has enough pressure to be sprayed out, in actual use, an atomizing nozzle can be installed at the end of the first shunt pipe 65 to make the paint sprayed more uniformly, when the mounting block 5 moves to the uppermost part, the rotating seat 502 contacts the fourth pressure sensitive switch 662, and then the electromagnetic valve 66 is closed at this time, at this time, the paint is no longer sprayed out, and the slide 21 is completely painted, when the slide 21 does not need to be repaired, the paint tank 79 can be disassembled to save space.

[0050] Example three

[0051] Referring to Figure 5 and Figure 8 , on the basis of example one, further, a second mounting pipe 67 is also fixedly connected in a mounting frame 6 close to the screening bin 3, a plurality of second shunt pipes 68 are fixedly connected to the middle part of the second mounting pipe 67, and the end of the second mounting pipe 67 is connected with an external hot air machine.

[0052] When the paint is finished, the paint tank 79 is removed, and the slide 21 is controlled to move down, at this time the polishing disc 57 and the scraping block 61 are not in contact with the slide 21, and the first branch pipe 65 no longer sprays paint, then the external hot air blower is connected to the second mounting pipe 67, at this time the mounting block 5 continues to move reciprocally, so that the hot air is blown out through the second mounting pipe 67 and the second branch pipe 68 in turn, completing the baking of the paint surface, so that the paint surface can be quickly dried.

[0053] Referring to Figures 1-3 The support part comprises a support plate 36, and the upper surface of the support plate 36 is fixedly connected with a second electric telescopic rod 37, and the top of the second electric telescopic rod 37 is fixedly connected with the lower surface of the slide 21.

[0054] The number of the second electric telescopic rods 37 should be at least two, so as to stably support the slide 21, and the setting of the support plate 36 enables the second electric telescopic rods 37 to be installed, and the synchronous extension and shortening of the plurality of second electric telescopic rods 37 can drive the slide 21 to move up or down, completing the contact and separation of the slide 21 and the polishing disc 57, so that the slide 21 can be in contact with the polishing disc 57 and be polished by the polishing disc 57.

[0055] Working principle: when in use, the material to be screened is put into the hopper 1, the material in the hopper 1 slides through the rectangular cylinder 2 into the screening bin 3 for screening, the material in the hopper 1 is discharged by using the existing technology to vibrate, the light supplementing lamp 31 probes the material, the sensor 32 captures the color of the material falling at high speed, the signal is transmitted to the terminal and controls the air nozzle 33, the air nozzle 33 blows out the material of the color other than the set color, the blown-out material enters the first discharge cylinder 34 and slides out, and the material of the set color slides out through the second discharge cylinder 35, the slide 21 is arranged at the lower part of the rectangular cylinder 2, and the side edge of the slide 21 is attached to the inner wall of the rectangular cylinder 2, so that the material does not run out from the gap between the slide 21 and the rectangular cylinder 2 when sliding on the slide 21, when the slide 21 is damaged and needs to be repaired, the slide 21 is controlled to rise in the rectangular cylinder 2, so that the slide 21 contacts the polishing disc 57 at the lower part of the mounting block 5, then the driving part is started to control the mounting block 5 to slide reciprocally, and the polishing disc 57 rotates at this time, the mounting block 5 drives the polishing disc 57 to polish the slide 21, so that the slide 21 is polished to be flat, facilitating the flatness of the slide 21 after later paint spraying.

[0056] The number of the second electric telescopic rods 37 should be at least two, in order to stably support the slide 21. The support plate 36 is arranged so that the second electric telescopic rods 37 are installed. The slide 21 can be driven to move up or down by controlling the synchronous extension and shortening of the plurality of second electric telescopic rods 37, so as to complete the contact and separation of the slide 21 and the polishing disc 57, and enable the slide 21 to contact the polishing disc 57 to be polished by the polishing disc 57.

[0057] The starting motor 24 drives the driving shaft 25 to rotate. At this time, the first bevel gear 26 on the driving shaft 25 rotates. In the initial state, the first bevel gear 26 is engaged with the second bevel gear 28, and the second bevel gear 28 drives the slide rod 42 to rotate synchronously. The limiting protrusion 43 on the slide rod 42 slides in the screw rod 23, so that the slide rod 42 can drive the screw rod 23 to rotate. At this time, the rotating screw rod 23 can drive the rectangular block 501 to move axially on the screw rod 23, so that the mounting block 5 fixedly connected with the rectangular block 501 can move synchronously with the rectangular block 501. The installation column 27 can improve the overall mechanical strength of the slide rod 42, so that the service life of the slide rod 42 is improved when the screw rod 23 is rotated by the slide rod 42.

[0058] When the rectangular block 501 moves to the lower mounting seat 22, it can contact the second pressure sensitive switch 45. At this time, the second pressure sensitive switch 45 controls the extension of the first electric telescopic rod 4, so that the slide rod 42 is pushed to slide into the screw rod 23. At this time, the third bevel gear 29 is engaged with the first bevel gear 26, so that the direction of the screw rod 23 is turned. At this time, the screw rod 23 drives the rectangular block 501 to slide to the upper mounting seat 22. When the rectangular block 501 contacts the upper first pressure sensitive switch 44, the first electric telescopic rod 4 is shortened, so that the second bevel gear 28 is engaged with the first bevel gear 26 again. At this time, the direction of the screw rod 23 is turned again, so that the rectangular block 501 slides to the lower mounting seat 22. In this way, the mounting block 5 can reciprocate in the rectangular cylinder 2. The output end of the first electric telescopic rod 4 is rotatably connected with the slide rod 42 through the swivel joint 41, so that the arrangement of the first electric telescopic rod 4 does not interfere with the rotation of the screw rod 23.

[0059] When the mounting block 5 reciprocatingly slides in the rectangular cylinder 2, the rotating seat 502 on the mounting block 5 moves synchronously with the mounting block 5, at this time the rotating seat 502 drives the transmission teeth 202 to roll on the rack 201, and then the rack 201 drives the acceleration teeth 53 to rotate, at this time the acceleration teeth 53 drive the rotating shaft 52 to rotate, since the diameter of the transmission teeth 202 is much larger than that of the acceleration teeth 53, the rotating speed of the acceleration teeth 53 is faster, at this time the rotating speed of the rotating shaft 52 is faster, and then the rotating speed of the fifth bevel gear 54 on the rotating shaft 52 is fast, and then the fifth bevel gear 54 can drive the fourth bevel gear 55 to rotate fast, and then the mounting rod 56 rotates fast, and then the mounting rod 56 drives the polishing disc 57 to rotate fast, at this time the fast-rotating polishing disc 57 can polish the slide 21, so that the surface of the slide 21 is flat, and in actual use, the number of the polishing discs 57 can be increased or decreased according to the width of the slide 21, so that the polishing disc 57 can cover the width of the slide 21.

[0060] When the slide 21 moves upward, the upper surface of the slide 21 first contacts the scraping block 61, at this time the slide 21 that continues to rise exerts a pushing force on the scraping block 61, at this time the scraping block 61 slides upward relative to the mounting frame 6, and then the straight telescopic rod 62 shortens, the straight telescopic rod 62 is arranged to connect the scraping block 61 and the mounting frame 6, when the straight telescopic rod 62 shortens, the spring 63 is compressed synchronously, at this time the contact force between the scraping block 61 and the slide 21 is large, and then the scraping block 61 can generate a large friction force when it slides relative to the slide 21, so that the surface of the slide 21 is wiped by the scraping block 61, avoiding the influence of the residues on the slide 21 on the polishing of the polishing disc 57, since the distance between the mounting frame 6 and the slide 21 is greater than the distance between the polishing disc 57 and the slide 21, the slide 21 can first contact the scraping block 61 when it moves upward, and meanwhile, the contact between the mounting frame 6 and the polishing disc 57 and the slide 21 is avoided;

[0061] When the rotating shaft 52 rotates, the impeller 59 fixedly connected with the rotating shaft 52 rotates synchronously, since the impeller 59 rotates in the mounting cylinder 58, when the impeller 59 rotates in the mounting cylinder 58, it can cause negative pressure at the dust suction pipe 582, at this time the dust suction pipe 582 absorbs the floating matter generated when the polishing disc 57 polishes, the floating matter absorbed by the dust suction pipe 582 can enter the dust storage box 51 through the dust outlet pipe 581 and be stored, and meanwhile, the arrangement of the mounting frame 6 and the scraping block 61 makes the space where the polishing disc 57 is located relatively closed, and then the floating matter generated when the polishing disc 57 polishes the slide 21 is avoided from leaking out;

[0062] The setting of the bracket 71 enables the installation of the piston cylinder 7, and enables the mounting block 5 to drive the piston cylinder 7 to move synchronously, when the mounting block 5 moves, the acceleration tooth 53 rotates synchronously, and then the cylindrical cam 75 rotates synchronously, which is fixedly connected with the acceleration tooth 53, since the piston plate 72 is limited to slide in the piston cylinder 7, the piston plate 72 does not rotate relative to the piston cylinder 7, and then the cylinder 73 does not rotate relative to the piston cylinder 7, and then the cylindrical cam 75 rotates relative to the cylinder 73, at this time, the protrusion 74 in the cylinder 73 slides relative to the sliding groove on the cylindrical cam 75, and then the cylinder 73 can drive the piston plate 72 to reciprocate in the piston cylinder 7, so that the pressure in the piston cylinder 7 changes alternately between positive pressure and negative pressure.

[0063] Since the air inlet pipe 77 and the air outlet pipe 76 are both provided with the one-way valve 78, when the pressure in the piston cylinder 7 changes, the external air can be sucked into the piston cylinder 7 through the air inlet pipe 77, and the sucked air can be discharged into the paint tank 79 through the air outlet pipe 76, so that when the polishing disc 57 is driven by the mounting block 5 to polish the slide 21, the paint tank 79 can be pressurized at the same time, when the mounting block 5 moves to the lower part, the rotating seat 502 presses the third pressure-sensitive switch 661 at the lower part, and the electromagnetic valve 66 controlled by the third pressure-sensitive switch 661 is opened, when the electromagnetic valve 66 is opened, the mounting block 5 starts to move upwards, in this process, the paint in the paint tank 79 is sprayed onto the slide 21 after passing through the paint spraying pipe 641, the first mounting pipe 64 and the first shunt pipe 65 in turn, so as to repair the slide 21 by spraying paint, and the piston cylinder 7 still pressurizes the paint tank 79 when the mounting block 5 moves upwards, so as to ensure that the paint has enough pressure to be sprayed out, in actual use, an atomizing nozzle can be installed at the end of the first shunt pipe 65, so that the paint can be sprayed out more uniformly, when the mounting block 5 moves to the uppermost part, the rotating seat 502 contacts the fourth pressure-sensitive switch 662, and then the electromagnetic valve 66 is closed at this time, at this time, the paint is not sprayed out any more, and the slide 21 is also completely painted, when the slide 21 does not need to be repaired, the paint tank 79 can be disassembled to save space.

[0064] When the paint spraying is completed, the paint tank 79 is disassembled, and then the slide 21 is controlled to move downwards, at this time, the polishing disc 57 and the scraping block 61 do not contact the slide 21 any more, and the first shunt pipe 65 does not spray out paint any more, then an external hot air machine is connected to the second mounting pipe 67, at this time, the mounting block 5 continues to move reciprocally, so that the hot air is blown out through the second mounting pipe 67 and the second shunt pipe 68 in turn, and the baking of the paint surface is completed, so that the paint surface can be dried quickly.

[0065] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
