[0023] Preferably, a one-way bearing is fixedly sleeved on the upper part of the transmission rod, and the inner ring of the transmission wheel on the left side is fixedly sleeved on the outer ring of the one-way bearing.

[0024] A method for using an environmentally friendly spray-coated thread protection tool includes the following steps:

[0025] S1. First, start the circular conveyor, carrying the support plate, and rotate clockwise around the circumference between the main and secondary annular grooves. When the adjusting plate is at the rear end of the circular conveyor, the opening positions of the jacket and the adjusting plate are on the same side. When the support plate, carrying the pad and the jacket, slowly rotates to the feeding plate position, start the electric push rod to push the screw towards the jacket position. After the screw enters the jacket, the U-shaped push plate is pressed and moves into the U-shaped groove. At this time, the transmission rack and transmission gear on the side wall of the U-shaped push plate mesh, causing the transmission gear to drive the transmission rod and transmission wheel to rotate. The transmission belt and the two transmission... With the cooperation of the wheel, the adjusting rod drives the adjusting gear to rotate synchronously. At this time, the adjusting gear meshes with the arc-shaped toothed plate side wall at the bottom of the adjusting plate, so that the adjusting plate rotates 180 degrees at the top of the sleeve through the arc-shaped guide groove and the guide wheel rod. This makes the opening position of the adjusting plate and the opening position of the sleeve symmetrically offset, limiting the screw inside the sleeve. At this time, the positioning plate moves to the limit position inside the positioning groove, and the pressure rod at the top of the sleeve and the arc-shaped pressure plate at the bottom of the adjusting plate are released from the squeezing state. Under the elastic pressure of the movable spring, the movable rack carries the locking strip and is locked into the locking groove on the positioning plate.

[0026] S2. Then the support plate, along with the clamp and the screw after the limit, continues to rotate around the circumference. When the transmission gear ring of the outer ring of the pad rotates to the position of the arc rack, the nozzle and dust collector on the spraying frame are turned on. At this time, the pad rotates one revolution on the support plate and rotates synchronously with the screw to spray the upper part of the screw. When the transmission gear ring and the arc rack disengage, the return spring slides and resets on the surface of the slide bar with the gear sleeve. At this time, the side wall of the gear sleeve meshes with the side wall of the transmission gear ring, so that the transmission gear ring and the pad rotate one revolution in reverse to reset.

[0027] S3. When the jacket rotates to the discharge plate position on the ring conveyor, the discharge toothed ring on the side wall of the adjusting plate meshes with the discharge rack on the main support ring, causing the adjusting plate to rotate counterclockwise at the top of the jacket. At this time, the arc-shaped guide groove at the bottom of the adjusting plate slides with the guide wheel rod at the top of the jacket, so that the opening end on the adjusting plate and the opening end of the jacket are adjusted to the same side. After the adjusting plate rotates, the arc-shaped pressure plate at the bottom of the adjusting plate presses against the top of the pressure rod, causing the pressure rod to slide into the interior of the movable groove, causing the gear rod to rotate, moving the transmission rack on the left side, and causing the transmission rack to move upward with the locking strip to release the locking with the locking groove.

[0028] S4. Then, the compression spring recovers and pushes the positioning plate to slide inside the positioning groove, so that the positioning plate, along with the U-shaped push plate, pushes the sprayed screw from inside the jacket into the discharge plate for unloading. After unloading, the jacket continues to rotate on the top of the ring conveyor with the pad and support plate to the feeding plate position, and the feeding, spraying and unloading are repeated in sequence.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0030] In this invention, through the coordinated use of components such as the adjusting plate, U-shaped push plate, and adjusting gear, when the screw is pushed into the sleeve, the U-shaped push plate is pressed and moves into the U-shaped groove. At this time, the transmission rack on the side wall of the U-shaped push plate meshes with the transmission gear, causing the transmission gear to rotate with the transmission rod and transmission wheel. Under the action of the transmission belt, the adjusting gear rotates synchronously. At this time, the adjusting gear meshes with the arc-shaped toothed plate side wall at the bottom of the adjusting plate, causing the adjusting plate to rotate 180 degrees at the top of the sleeve through the arc-shaped guide groove and the guide wheel rod, thus limiting the screw and facilitating quick and convenient positioning and installation of the screw.

[0031] In this invention, through the coordinated use of components such as the unloading toothed ring, the arc-shaped pressure plate, and the U-shaped push plate, when the jacket rotates to the discharge plate position on the ring conveyor, the unloading toothed ring on the side wall of the adjusting plate meshes with the unloading rack on the main support ring, causing the adjusting plate to rotate counterclockwise at the top of the jacket to release the restriction on the screw. At this time, the arc-shaped pressure plate at the bottom of the adjusting plate presses against the top of the pressure rod, causing the transmission rack to move upward with the locking strip to release the engagement with the locking groove. Then, the compression spring elastically recovers and presses the positioning plate to slide inside the positioning groove, causing the positioning plate to push the sprayed screw from inside the jacket into the discharge plate for unloading, thus achieving the effect of automatic unloading and reducing the labor intensity of workers.

[0032] In this invention, by using components such as an arc-shaped rack, a transmission gear ring, and a dust collector in combination, when the support plate moves with the pad to the position of the arc-shaped rack, the transmission gear ring meshes with the side wall of the arc-shaped rack, causing the pad, along with the sleeve and the screw, to rotate once on the top of the support plate, so that the upper part of the screw is uniformly sprayed. During the spraying process, the dust collector extracts the paint mist generated during spraying, thus improving the environmental protection effect. Attached Figure Description

Detailed Implementation

[0050] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] Please see Figures 1 to 16The present invention provides a technical solution: an environmentally friendly spray-coated thread protection tooling, including a ring conveyor 1, a main support ring 2 fixedly connected to the inner ring of the top of the ring conveyor 1, a secondary support ring 3 fixedly connected to the outer ring of the top of the ring conveyor 1, a main ring groove 4 opened inside the main support ring 2, a secondary ring groove 5 opened inside the secondary support ring 3, a guide rod 6 movably connected inside both the main ring groove 4 and the secondary ring groove 5, a support plate 7 fixedly connected between the two guide rods 6, and the bottom of the support plate 7 overlapping the top of the ring conveyor 1. It should be noted that: the conveyor belt inside the ring conveyor is a metal mesh conveyor belt, and the bottom of the support plate 7 is provided with positioning pins that cooperate with the metal mesh conveyor belt, so that the ring conveyor can stably move the support plate 7 during the transmission process. The ring conveyor is existing technology and will not be described in detail here; the end of the guide rod 6 away from the support plate 7 is rotatably connected to a guide wheel, and the two guide wheels are slidably connected inside the secondary ring groove 5 and the main ring groove 4 respectively. The support plate 7 and the guide rod 6 are fixedly installed by bolts, so that the support plate 7 and the jacket 10 can be easily replaced.

[0052] A pad 8 is movably connected to the top of the support plate 7, and a transmission mechanism 9 is movably connected between the top of the pad 8 and the main support ring 2. It should be noted that a circular groove is opened on the top of the support plate 7, and a support bearing is fixedly connected to the bottom of the pad 8. The outer ring of the support bearing is fixedly connected to the inner ring of the circular groove, so that the pad 8 can rotate stably on the top of the support plate 7.

[0053] A sleeve 10 is fixedly connected to the top of the pad 8, an adjusting plate 11 is movably connected to the top of the sleeve 10, and a discharge mechanism 12 is movably connected to the inner wall of the sleeve 10. An arc-shaped pressure plate 13 that cooperates with the discharge mechanism 12 is fixedly connected to the bottom of the adjusting plate 11. It should be noted that both ends of the arc-shaped pressure plate 13 are beveled to facilitate cooperation with the arc-shaped surface of the pressure rod 1214 on the discharge mechanism 12. When the adjusting plate 11 rotates at the top of the sleeve 10, the arc-shaped pressure plate 13 can press the pressure rod 1214 downward.

[0054] An adjusting mechanism 14 is movably connected between the bottom of the adjusting plate 11 and the top of the jacket 10. One side of the adjusting mechanism 14 is movably connected to one side of the unloading mechanism 12. The adjusting plate 11 and the jacket 10 have the same cross-sectional shape. An unloading toothed ring 21 is fixedly connected to the outer ring of the adjusting plate 11, and an unloading rack 22 that cooperates with the unloading toothed ring 21 is fixedly connected to the outer ring of the main support ring 2. It should be noted that when the adjusting plate 11 moves with the support plate 7 to the position of the unloading rack 22, the unloading toothed ring 21 on the adjusting plate 11 meshes with the unloading rack 22. At this time, the adjusting plate 11 rotates 180 degrees on the top of the jacket 10, and the jacket 10 moves with the screw to the position of the discharge plate 15 for material discharge. A sealing strip is fixedly connected to the inner ring of the jacket 10 and the adjusting plate 11. When the openings of the jacket 10 and the adjusting plate 11 are misaligned, the screw surface can be sealed. At the same time, the sealing strip can increase the frictional resistance when positioning the screw and improve stability.

[0055] A discharge plate 15 is fixedly connected to the left side of the circular conveyor 1, and a feed plate 16 is fixedly connected to the right side of the circular conveyor 1. It should be noted that the feed plate 16 and the discharge plate 15 are at the same height, and the bottom of the jacket 10 is flush with the height of the feed plate 16, which facilitates feeding and unloading.

[0056] An electric push rod 17 is fixedly connected to the right side of the inner wall of the feeding plate 16. A push block 18 is fixedly connected to one end of the electric push rod 17. A spraying frame 19 that cooperates with the transmission mechanism 9 is fixedly connected to the front end of the circular conveyor 1. A dust collector 20 is fixedly connected to the side wall of the spraying frame 19. It should be noted that the spraying frame 19 is inclined, and the nozzle of the spraying frame 19 is higher than the top surface of the adjusting plate 11, so that the nozzle tilts downward and sprays the surface of the screw clamped on the top surface of the adjusting plate 11. When the opening of the adjusting plate 11 is misaligned with the opening of the jacket 10, the lower part of the screw can be effectively shielded and sealed to prevent paint from falling on the teeth of the screw. The dust collector 20 can effectively reduce the paint mist floating in the surrounding environment during the spraying process, avoid pollution to the surrounding environment, and improve the environmental protection effect.

[0057] In this embodiment, as Figures 1 to 16 As shown, the transmission mechanism 9 includes a transmission gear ring 901, the inner ring of which is fixedly sleeved on the outer ring of the pad 8. It should be noted that the pad 8 is designed as an annular plate to facilitate installation with the transmission gear ring 901 and the clamping sleeve 10.

[0058] A pad 902 is symmetrically fixedly connected to the top of the support plate 7. A slide rod 903 is fixedly connected between the two pads 902. A toothed sleeve 904 is slidably connected to the surface of the slide rod 903. The side wall of the toothed sleeve 904 meshes with the side wall of the transmission gear ring 901. A return spring 905 is movably sleeved on the surface of the slide rod 903. It should be noted that the toothed sleeve 904 has teeth on the side near the transmission gear ring 901, so that the toothed sleeve 904 can mesh with the transmission gear ring 901 when sliding on the surface of the slide rod 903, and rotate the transmission gear ring 901 and the pad 8. When the toothed sleeve 904 moves from one end to the other on the slide rod 903, the transmission gear ring 901 can rotate the pad 8 one revolution. The slide rod 903 has a rectangular cross-section to prevent the toothed sleeve 904 from rotating on the surface of the slide rod 903 and affecting the use effect.

[0059] Three arc-shaped racks 906 are fixedly connected to the inner ring of the support ring 3, which cooperate with the transmission gear ring 901. The three arc-shaped racks 906 are equidistantly positioned at the spraying frame 19. It should be noted that: by having the three arc-shaped racks 906 correspond one-to-one with the three nozzles on the spraying frame 19, when the pad 8 moves with the screw on the jacket 10 to the position of the arc-shaped rack 906, the transmission gear ring 901 rotates one revolution each time it meshes with one arc-shaped rack 906, allowing the nozzles on the spraying frame 19 to perform multiple uniform spraying processes on the screw.

[0060] In this embodiment, as Figures 1 to 16 As shown, one end of the return spring 905 is attached to the side wall of the gear sleeve 904, and the other end of the return spring 905 is attached to the side wall of the adjacent pad 902. It should be noted that when the transmission gear ring 901 disengages from the arc-shaped rack 906, the return spring 905 moves the gear sleeve 904, causing the transmission gear ring 901 to rotate one revolution to reset.

[0061] In this embodiment, as Figures 1 to 16 As shown, the unloading mechanism 12 includes a U-shaped groove 1201, which is formed on the inner wall of the jacket 10. A U-shaped push plate 1202 is slidably connected inside the U-shaped groove 1201. A transmission rack 1203 is movably connected to the side wall of the U-shaped push plate 1202. The side wall of the transmission rack 1203 is movably connected to one side of the adjustment mechanism 14.

[0062] A positioning groove 1204 is formed in the middle of the inner wall of the U-shaped groove 1201. A positioning plate 1205 that mates with the positioning groove 1204 is fixedly connected to the middle of the U-shaped push plate 1202. Slider blocks 1206 are fixedly connected to both sides of the positioning plate 1205. Sliding grooves 1207 are formed on both sides of the inner wall of the positioning groove 1204. The two sliders 1206 are slidably connected inside the two sliding grooves 1207 respectively. A compression spring 1208 is fixedly connected between the side wall of the slider 1206 and the inner wall of the sliding groove 1207. A retaining groove 1209 is formed on the top of the positioning plate 1205. It should be noted that a push rod is slidably connected in the middle of the positioning plate 1205 to facilitate the ejection of the screw.

[0063] The upper part of the sleeve 10 is provided with a movable groove 1210 that cooperates with the positioning groove 1204, and a gear rod 1211 is rotatably connected between the two sides of the inner wall of the movable groove 1210.

[0064] Movable racks 1212 are slidably connected to both sides of the inner wall of the movable groove 1210. The side walls of the two movable racks 1212 mesh with the two sides of the gear rod 1211 respectively. One end of the left movable rack 1212 is fixedly connected to a retaining strip 1213 that cooperates with the retaining groove 1209, and one end of the right movable rack 1212 is fixedly connected to a pressure rod 1214 that cooperates with the arc-shaped pressure plate 13. It should be noted that when the opening of the adjusting plate 11 and the opening of the jacket 10 are symmetrically misaligned, the arc-shaped pressure plate 13 can press against the top of the pressure rod 1214. The lower part of the inner wall of the jacket 10 is symmetrically provided with limiting grooves. Limiting rods are slidably connected inside the limiting grooves. A limiting spring is fixedly connected between one end of the limiting rod and the inner wall of the limiting groove. Rubber blocks are fixedly connected to the opposite ends of the two limiting rods. The lower part of the screw is clamped by the two limiting rods to ensure the stability of the lower part of the screw during transmission.

[0065] The other ends of the two movable racks 1212 are fixedly connected to the inner wall of the movable groove 1210 by movable springs 1215. It should be noted that: one side of the retaining strip 1213 is set as an inclined surface. When the retaining strip 1213 passes through the movable groove 1210 and is inserted into the positioning groove 1204, the positioning plate 1205 can press against the inclined surface of the retaining strip 1213 when sliding inside the positioning groove 1204, so that the retaining strip 1213 moves into the movable groove 1210 and avoids interference; and the inner wall of the movable groove 1210 is fixedly connected with a sealing ring that matches the side wall of the pressure rod 1214. Both sides of the inner wall of the movable groove 1210 are provided with rectangular grooves. A rectangular block is fixedly connected to the side of the movable rack 1212 away from the gear rod 1211. The rectangular block is slidably connected inside the corresponding rectangular groove.

[0066] In this embodiment, as Figures 1 to 16As shown, a guide groove is provided at the lower part of the inner wall of the U-shaped groove 1201, and a guide plate is fixedly connected to the lower part of the side wall of the U-shaped push plate 1202. The guide plate is slidably connected inside the guide groove. It should be noted that the guide plate cooperates with the positioning plate 1205 to ensure that the U-shaped push plate 1202 remains stable up and down when moving inside the U-shaped groove 1201.

[0067] In this embodiment, as Figures 1 to 16 As shown, the adjustment mechanism 14 includes an arc-shaped guide groove 1401, which is formed at the bottom of the adjustment plate 11. A guide wheel rod 1402 is fixedly connected to the top of the sleeve 10, and the upper part of the guide wheel rod 1402 is slidably connected inside the arc-shaped guide groove 1401. It should be noted that a ball bearing is provided at the bottom of the adjustment plate 11, and the bottom of the ball bearing overlaps the top of the sleeve 10, which improves the stability of the adjustment plate 11 during rotation.

[0068] An adjustment groove 1403 is provided on the upper part of the jacket 10. A transmission rod 1404 is rotatably connected to the inner bottom surface of the adjustment groove 1403. A transmission gear 1405 is fixedly connected to the middle of the transmission rod 1404. The side wall of the transmission gear 1405 penetrates the adjustment groove 1403 and meshes with the side wall of the unloading mechanism 12. It should be noted that the adjustment groove 1403 is connected to the U-shaped groove 1201, and the side wall of the transmission gear 1405 extends into the U-shaped groove 1201 and meshes with the side wall of the transmission rack 1203.

[0069] An adjusting rod 1406 is rotatably connected to the side of the adjusting groove 1403 away from the transmission rod 1404. A transmission wheel 1407 is fixedly connected to the middle of the adjusting rod 1406 and the top of the transmission rod 1404. A transmission belt 1408 is movably connected between the two transmission wheels 1407. An adjusting gear 1409 is fixedly connected to the top of the adjusting rod 1406 through the adjusting groove 1403. It should be noted that a sealing ring is movably connected between the inner wall of the adjusting groove 1403 and the side wall of the adjusting rod 1406 to improve the sealing effect at the position of the adjusting rod 1406.

[0070] An arc-shaped toothed plate 1410 is fixedly connected to the bottom of the adjusting plate 11, and the side wall of the arc-shaped toothed plate 1410 meshes with the side wall of the adjusting gear 1409.

[0071] In this embodiment, as Figures 1 to 16As shown, the cross-section of the arc-shaped guide groove 1401 is T-shaped, and the arc-shaped guide groove 1401 is a semi-circular groove. It should be noted that when the transmission rack 1203 meshes with the transmission gear 1405, the transmission belt 1408 drives the adjusting gear 1409 to mesh with the arc-shaped toothed plate 1410, causing the adjusting plate 11 to rotate. When the transmission rack 1203 and the transmission gear 1405 are meshed to the limit position, during the meshing process of the adjusting gear 1409 and the arc-shaped toothed plate 1410, the adjusting plate 11 rotates 180 degrees at the top of the main sleeve 10. At this time, the opening of the adjusting plate 11 and the sleeve 10 are misaligned, which perfectly wraps around the screw.

[0072] In this embodiment, as Figures 1 to 16 As shown, a one-way bearing is fixedly sleeved on the upper part of the transmission rod 1404, and the inner ring of the left transmission wheel 1407 is fixedly sleeved on the outer ring of the one-way bearing. It should be noted that when the transmission rod 1404 rotates, it can synchronously rotate the top transmission wheel 1407. However, when the transmission belt 1408 rotates the transmission wheel 1407, the transmission wheel 1407 can only rotate the outer ring of the one-way bearing, and cannot rotate the transmission rod 1404 through the one-way bearing, thus avoiding interference.

[0073] In this embodiment, as Figures 1 to 16 As shown, a method for using an environmentally friendly spray-coated thread protection tool includes the following steps:

[0074] S1. First, start the annular conveyor 1, which carries the support plate 7 and rotates clockwise around the circumference between the main annular groove 4 and the secondary annular groove 5. When the adjusting plate 11 is at the rear end of the annular conveyor 1, the opening positions of the jacket 10 and the adjusting plate 11 are on the same side. When the support plate 7, carrying the pad 8 and the jacket 10, slowly rotates to the position of the feeding plate 16, start the electric push rod 17 to push the screw towards the position of the jacket 10. After the screw enters the inside of the jacket 10, the U-shaped push plate 1202 is pressed and moves into the U-shaped groove 1201. At this time, the transmission rack 1203 on the side wall of the U-shaped push plate 1202 meshes with the transmission gear 1405, causing the transmission gear 1405 to drive the transmission rod 1404 and the transmission wheel 1407 to rotate. With the cooperation of the transmission belt 1408 and the two transmission wheels 1407, The adjusting rod 1406 rotates synchronously with the adjusting gear 1409. At this time, the adjusting gear 1409 meshes with the side wall of the arc-shaped toothed plate 1410 at the bottom of the adjusting plate 11, so that the adjusting plate 11 rotates 180 degrees at the top of the sleeve 10 through the arc-shaped guide groove 1401 and the guide wheel rod 1402. This makes the opening position of the adjusting plate 11 and the opening position of the sleeve 10 symmetrically offset, limiting the screw inside the sleeve 10. At this time, the positioning plate 1205 moves to the limit position inside the positioning groove 1204, and the pressure rod 1214 at the top of the sleeve 10 and the arc-shaped pressure plate 13 at the bottom of the adjusting plate 11 are released from the squeezing state. Under the elastic pressure of the movable spring 1215, the movable rack 1212 with the locking strip 1213 is inserted into the locking groove 1209 on the positioning plate 1205.

[0075] S2. Then, the support plate 7, along with the sleeve 10 and the limited screw, continues to rotate around the circumference. When the transmission gear ring 901 on the outer ring of the pad 8 rotates to the position of the arc rack 906, the nozzle and dust collector 20 on the spray frame 19 are opened. At this time, the pad 8 rotates once on the support plate 7 and rotates synchronously with the screw to spray the upper part of the screw. When the transmission gear ring 901 and the arc rack 906 disengage, the return spring 905 slides and resets on the surface of the slide bar 903 with the toothed sleeve 904. At this time, the side wall of the toothed sleeve 904 engages with the side wall of the transmission gear ring 901, causing the transmission gear ring 901 to rotate once in reverse and reset with the pad 8.

[0076] S3. When the jacket 10 rotates to the position of the discharge plate 15 on the ring conveyor 1, the discharge tooth ring 21 on the side wall of the adjusting plate 11 meshes with the discharge rack 22 on the main support ring 2, so that the adjusting plate 11 rotates counterclockwise at the top of the jacket 10. At this time, the arc-shaped guide groove 1401 at the bottom of the adjusting plate 11 and the guide wheel rod 1402 at the top of the jacket 10 cooperate and slide, so that the opening end on the adjusting plate 11 and the opening end of the jacket 10 are adjusted to the same side. After the adjusting plate 11 rotates, the arc-shaped pressure plate 13 at the bottom of the adjusting plate 11 presses against the top of the pressure rod 1214, so that the pressure rod 1214 slides into the interior of the movable groove 1210, so that the gear rod 1211 rotates, and moves the transmission rack 1203 on the left side, so that the transmission rack 1203 moves upward with the locking strip 1213 to release the locking with the locking groove 1209.

[0077] S4. Next, the compression spring 1208 elastically recovers and pushes the positioning plate 1205 to slide inside the positioning groove 1204, so that the positioning plate 1205, along with the U-shaped push plate 1202, pushes the sprayed screw from inside the jacket 10 into the discharge plate 15 for unloading. After unloading, the jacket 10 continues to rotate on the top of the ring conveyor 1 to the position of the loading plate 16 along with the pad 8 and the support plate 7. At this time, the opening of the jacket 10 and the opening of the adjusting plate 11 are on the same side, and the loading, spraying and unloading are repeated in sequence.
