[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] Reference Figure 1-12 , a sucker rod coating production system, comprising a spraying part for spraying a rod body 8 of the sucker rod and a supporting part for supporting the rod body 8; The spraying part includes a clamping mechanism for clamping and rotating the rod body 8, a spraying mechanism for spraying operation, and a drying mechanism for drying operation; The clamping mechanism moves horizontally through the translation mechanism, and two sets of reciprocating drive mechanisms are arranged on the clamping mechanism, corresponding to the spraying mechanism and the drying mechanism respectively; The supporting part comprises a side support 13 and a plurality of supporting frames. A disconnecting portion is arranged on the top of the supporting frame, and the position of the disconnecting portion of each supporting frame is different.

[0036] In a specific embodiment of the present invention, the clamping mechanism is used to clamp the two ends of the rod body 8 and can drive the rod body 8 to rotate. By rotating the rod body 8, only one spray head 26 is needed to spray the annular surface of the rod body 8 during the spraying operation. The translation mechanism can drive the clamping mechanism to move horizontally, thereby driving the rod body 8 to move horizontally. During the horizontal movement, in order to avoid large surface friction between the rod body 8 and the support frame, which may cause damage to the surface of the rod body 8, the clamping mechanism needs to be used to rotate the rod body 8 during the movement, so that the linear speed of the rod body 8 is equal to the horizontal movement speed of the clamping mechanism, so as to achieve the effect of the rod body 8 rolling on the support frame and avoid large wear on the surface of the rod body 8. The baking mechanism can bake the sprayed area to speed up the drying of the paint in the area so that it is not easy to be scratched or left with marks. By providing a support frame with a disconnection portion, during the spraying operation, when the rod body 8 passes through the disconnection portion, the spraying mechanism just sprays on the area of ​​the rod body 8, so that the spraying mechanism does not spray on the support frame, thereby ensuring the original shape of the support frame and preventing the area from becoming thicker due to long-term spraying of paint, thereby affecting the support of other rod bodies 8 in the later stage. At the same time, spraying paint on the rod body 8 at the disconnection portion can avoid the problem of incomplete paint on the area of ​​the rod body 8 that has just been sprayed contacting the support frame, and at the same time, with a drying mechanism, the above-mentioned problem can be further avoided. In this embodiment, four support frames are provided, and the disconnecting portions on each support frame are provided as follows: Figure 3 , counting from left to right, the breaking portion on the first support frame is located near the front end, and then the breaking portion on the second support frame is offset backwards from the breaking portion on the first support frame, and so on, the breaking portion on the third support frame is offset backwards from the breaking portion on the second support frame, and the breaking portion on the fourth support frame is offset backwards from the breaking portion on the third support frame. In this way, when the rod body 8 moves on the support frame, there will always be a support frame to support the rod body 8, and then when the rod body 8 is located at a certain breaking portion, the spraying operation and drying operation of the area of ​​the rod body 8 are carried out.

[0037] The clamping mechanism includes two mounting plates 14, a turntable 17 is rotatably provided at the bottom of the mounting plate 14, a jacket 31 is detachably provided on the inner end surface of the turntable 17, the turntable 17 is driven to rotate by a driving mechanism, the driving mechanism includes a first gear 16 and a second gear 18, the second gear 18 is fixedly provided on the turntable 17, the first gear 16 is rotatably provided on the mounting plate 14, the first gear 16 and the second gear 18 are meshingly connected, the first gear 16 is driven to rotate by a motor, and the motor is fixedly provided at the lower part of the mounting plate 14. When in use, the motor drives the first gear 16 to rotate, and then the first gear 16 drives the second gear 18 to rotate, the second gear 18 drives the turntable 17 to rotate, and then drives the jacket 31 to rotate, thereby driving the rod body 8 connected to the jacket 31 to rotate. Preferably, the motor can adopt a stepping servo motor to facilitate control of the rotation speed.

[0038] A square column is fixedly provided at the outer end of the jacket 31, and a square hole is opened in the middle of the turntable 17. The square column can be inserted into the square hole, and then the bolt 32 is screwed into the square column to realize the detachable connection between the jacket 31 and the turntable 17. Through this arrangement, the jacket 31 can be easily replaced to match the bosses 33 of different sizes.

[0039] The clamping mechanism further includes a protective sleeve 30 disposed at both ends of the rod body 8 . A boss 33 is disposed at the outer end of the protective sleeve 30 . The outer diameter of the boss 33 matches the inner diameter of the clamping sleeve 31 .

[0040] In the prior art, when the sucker rod is being painted, a protective sleeve is also used to protect both ends of the sucker rod. The protective sleeve is threadedly connected to the sucker rod to prevent the end threads of the sucker rod from being sprayed with paint or being damaged by other collisions during painting, which may affect the normal connection of the subsequent sucker rod. The protective sleeve 30 provided in the present scheme is, on the one hand, to achieve the above-mentioned effect, and on the other hand, a boss 33 is provided on the protective sleeve 30, which can be used to match and dock with the jacket 31. The outer diameter of the boss 33 can be guaranteed to be uniform, but the threaded holes threadedly connected to the sucker rod can be of different diameters, so as to realize the processing of sucker rods of different diameters without replacing the jacket 31. If the boss 33 cannot be unified due to the influence of the sucker rod diameter, the corresponding jacket 31 can be replaced.

[0041] The support frame is composed of a base plate 10 and two support frames 9. The two support frames 9 are fixedly arranged on the top surface of the base plate 10, and the two support frames 9 do not contact each other. The distance between them forms a disconnected part of the support frame. The top surface of the support frame 9 supports the rod body 8.

[0042] The side support 13 is used to support the protective cover 30, that is, to support the two ends of the rod body 8; a third telescopic rod 12 is fixedly provided on the upper front end of the side support 13, and a U-shaped limit block 11 is fixedly provided on the telescopic end of the third telescopic rod 12. The opening width of the U-shaped limit block 11 is equal to the outer diameter of the protective cover 30. Through this arrangement, the rod body 8 can be positioned, which is convenient for the clamping mechanism to clamp the protective cover 30 at both ends of the rod body 8; the third telescopic rod 12 can adopt an electromagnetic telescopic rod, which can drive the U-shaped limit block 11 to move up and down.

[0043] The clamping mechanism also includes a guide rail 7 and a screw rod. The screw rod is rotatably arranged in the guide rail 7 and is driven to rotate by a motor. A second slider 34 is fixedly arranged on the top of the mounting plate 14. The second slider 34 is slidably arranged in the guide rail 7 and is threadedly connected to the screw rod. The screw rod is provided with two threaded sections in opposite directions. The two second sliders 34 are threadedly connected to the two threaded sections respectively. When in use, the motor drives the screw rod to rotate to realize the movement of the two second sliders 34 in opposite directions, so as to realize the two mounting plates 14 approaching or moving away from each other, thereby achieving the clamping effect. In some other embodiments, a gear rack method can also be used to realize the two mounting plates 14 approaching or moving away from each other, or a cylinder can be used to drive the two mounting plates 14 to approach or move away from each other.

[0044] The reciprocating drive mechanism includes two fixed plates 15 and two synchronous wheels 19. The two fixed plates 15 are respectively fixedly arranged at the two ends of the guide rail 7. The two synchronous wheels 19 are respectively rotatably arranged on the two fixed plates 15. The two synchronous wheels 19 are connected by a synchronous belt 20. One of the synchronous wheels 19 is driven to rotate by a motor. When in use, the motor is used to drive the synchronous wheel 19 to rotate, and then the synchronous belt 20 will perform a rotary motion. In some other embodiments, a sprocket chain or a belt pulley can also be used to achieve the above effect.

[0045] The reciprocating drive mechanism also includes a guide rod 24, both ends of which are fixedly connected to two fixed plates 15, one of which is installed on the front side of the guide rail 7, and the other is installed on the back side of the guide rail 7, a spraying mechanism, and a drying mechanism for drying operations.

[0046] The spraying mechanism includes a mounting frame 25 and a spray head 26. The upper part of the mounting frame 25 is slidably connected to the guide rod 24 in the reciprocating drive mechanism located on the front. The top of the mounting frame 25 is fixedly connected to the synchronous belt 20 in the reciprocating drive mechanism. The spray head 26 is installed at the lower part of the mounting frame 25, and the spray head 26 is connected to the paint sprayer through a paint tube. When the corresponding synchronous belt 20 moves, it will drive the mounting frame 25 to move along the guide rod 24, so that the spray head 26 can move along the radial direction of the rod body 8 to spray the rod body 8. At the same time, since the reciprocating drive mechanism is arranged on the guide rail 7, when the clamping mechanism drives the rod body 8 to move horizontally, the spray head 26 can always spray the rod body 8.

[0047] The drying mechanism includes a support tube 23 and a heating lamp 28. The heating lamp 28 is connected to the support tube 23 through an adjustment mechanism for adjusting the position of the heating lamp 28. The upper part of the support tube 23 is slidably connected to the guide rod 24 in the reciprocating drive mechanism on the back, and the top of the support tube 23 is fixedly connected to the synchronous belt 20 in the reciprocating drive mechanism; when the corresponding synchronous belt 20 moves, it will drive the support tube 23 to move along the corresponding guide rod 24, so that the heating lamp 28 can move along the radial direction of the rod body 8 to dry the area of ​​the rod body 8 that has been sprayed. At the same time, since the reciprocating drive mechanism is arranged on the guide rail 7, when the clamping mechanism drives the rod body 8 to move horizontally, the heating lamp 28 can also always face the rod body 8 for drying.

[0048] The adjustment mechanism includes a support rod 27, a connecting rod 29, a first telescopic rod 21 and a second telescopic rod 22. The support rod 27 is slidably arranged in the lower part of the support tube 23. One end of the second telescopic rod 22 is fixedly connected to the support tube 23, and the other end is fixedly connected to the support rod 27. The connecting rod 29 is slidably arranged at the bottom of the support rod 27. One end of the first telescopic rod 21 is fixedly connected to the support rod 27, and the other end is fixedly connected to one end of the connecting rod 29. The heating lamp 28 is fixedly arranged at the other end of the connecting rod 29. The extension and retraction of the second telescopic rod 22 can drive the support rod 27 to move up and down, and then the heating lamp 28 can be driven to move up and down. The extension and retraction of the first telescopic rod 21 can drive the connecting rod 29 to move horizontally, and then the heating lamp 28 can be driven to move horizontally.

[0049] The translation mechanism includes a fixed frame 2, a lead screw 3 and a limit rod 5. The lead screw 3 is rotatably arranged inside the fixed frame 2, and the limit rod 5 is fixedly arranged inside the fixed frame 2. A first slider 4 and a limit block 6 are fixedly arranged on the top surface of the guide rail 7. The first slider 4 is threadedly connected to the lead screw 3, and the limit block 6 is slidably connected to the limit rod 5. The fixed frame 2 is supported by the support leg 1. When in use, the motor drives the lead screw 3 to rotate, so that the guide rail 7 can move horizontally along the limit rod 5.

[0050] The working process is as follows: first, the protective sleeves 30 are screwed onto the two ends of the rod body 8 to be processed, and then the rod body 8 to be processed is placed on the side support 13 and the support frame by a loading device or a manual loading method, and then the third telescopic rod 12 drives the U-shaped limit block 11 to move up and clamp the protective sleeves 30 at both ends of the rod body 8 respectively, and then the translation mechanism drives the clamping mechanism to move forward to the upper position of the rod body 8, and then the two sleeves 31 of the clamping mechanism are sleeved on the bosses 33 of the two protective sleeves 30 to clamp the rod body 8, and then the U-shaped limit block 11 moves down, and the translation mechanism drives the clamping mechanism to move backward. At the same time, the turntable 17 rotates to drive the sleeves 31 rotation makes the rod body 8 rotate, and then the spraying mechanism moves to the left side, so that the spray head 26 is located above the end of the rod body 8 (the position of the sucker rod shoulder), and the spray head 26 is aimed at the rod body 8. At this time, the drying mechanism is also located here, but its baking lamp 28 is driven away from the rod body 8 by the adjustment mechanism, and its height is not lower than the spray head 26 (to avoid spraying paint on the baking lamp 28). Then, when the rod body 8 reaches the disconnection part on the first support frame, the other support frames still support the rod body 8. At this time, the spray head 26 sprays paint on the rod body 8 and slowly moves to the right. Since the rod body 8 is rotating, it can ensure that the rod body 8 is surrounded by The paint can be sprayed on all surfaces. When the spraying mechanism moves a certain distance to the right, the baking lamp 28, driven by the adjusting mechanism, first moves downward, and then approaches the rod body 8 but does not touch it, and bakes the rod body 8 in the painted area. When the spraying mechanism and the baking mechanism pass through the disconnection portion of the first support frame (that is, the spraying mechanism and the baking mechanism are both located between the first support frame and the second support frame), the rod body 8 moves to leave the disconnection portion on the first support frame and is supported by the first support frame again (in this process, the paint cannot be sprayed on the support frame, and the area on the rod body 8 that has just been sprayed will not be affected by the support frame). Since the painted area is dried faster by the baking lamp 28, it is not easy for the paint to fall off or be scratched when supported by the support frame at this time. Then, as in the above steps, the second support frame, the third support frame, and the fourth support frame are passed in sequence until the spraying mechanism sprays the entire rod body 8 with paint. In this way, the support frame is prevented from being sprayed, and the rod body 8 can be supported throughout the whole process. At the same time, the baking mechanism can also prevent the paint from falling off or being scratched. After the spraying is completed, the clamping mechanism releases the rod body 8, and the processed rod body 8 is removed by the unloading device or manual unloading, and then the next rod body 8 is processed.
