Description

Technical Field

[0001] The invention relates to the technical field of chemical fiber production equipment, in particular to a wind tube assembly device. Background Art

[0002] The air duct is a cooling device used for the production of various long and short fibers in the chemical fiber industry. It has mesh holes on its surface. The air duct includes an inner tube, an outer tube and a rubber ring. Annular protrusions are respectively provided at both ends of the outer surface of the inner tube. When the inner tube is put inside the outer tube, the two ends of the inner tube and the outer tube are aligned. At the same time, due to the limitation of the annular protrusions, an annular area exists between the inner tube and the outer tube. This area is used to place the rubber ring. When the rubber ring is placed in this area, the rubber ring will be squeezed. Through the elasticity of the rubber ring, the inner tube and the outer tube are clamped together. When assembling the air duct, it can only be assembled manually by employees, and the assembly efficiency is low. Summary of the invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The following further describes the specific embodiments of the present invention with reference to the accompanying drawings.

[0028] As Figures 1-10 shown, a hair dryer assembling device includes: An operating table; An inner cylinder 1 feeding mechanism, which is used to place the inner cylinder 1 and control the feeding of the inner cylinder 1; An outer cylinder 2 placing mechanism, which is used to place the outer cylinder 2 and drive the outer cylinder 2 to move at the same time; A rubber ring 51 feeding mechanism, which is used to place the rubber ring 51 and control the feeding of the rubber ring 51; A transfer mechanism, which is used to clamp and transfer the inner cylinder 1 at the inner cylinder 1 feeding mechanism, install the rubber ring 51 on the rubber ring 51 feeding mechanism at both ends of the inner cylinder 1, then transfer the inner cylinder 1 to the outer cylinder 2 placing mechanism, and press part of the inner cylinder 1 into the outer cylinder 2; A pressing-in mechanism, which is used to completely press the inner cylinder 1 into the outer cylinder 2.

[0029] A guiding mechanism, which is arranged on the pressing-in mechanism and is used to guide the inner cylinder 1 into the outer cylinder 2.

[0030] The hair dryer includes an inner cylinder 1, an outer cylinder 2 and a rubber ring 51. Annular protrusions are respectively arranged at both ends of the outer surface of the inner cylinder 1. When the inner cylinder 1 is sleeved inside the outer cylinder 2, the two ends of the inner cylinder 1 and the outer cylinder 2 are aligned. At the same time, due to the limitation of the annular protrusions, an annular area exists between the inner cylinder 1 and the outer sleeve. This area is used to place the rubber ring 51. When the rubber ring 51 is placed in this area, the rubber ring 51 will be squeezed. Through the elasticity of the rubber ring 51, the inner cylinder 1 and the outer cylinder 2 are clamped together. The outer diameter of the annular protrusion of the inner cylinder 1 is 170 mm, and the inner diameter of the outer cylinder 2 is 172 mm.

[0031] Furthermore, the operating table has a first installation platform 3 and a second installation platform 4. The height of the first installation platform 3 is higher than that of the second installation platform 4. The inner cylinder 1 feeding mechanism is arranged on the first installation platform 3, the outer cylinder 2 placing mechanism and the pressing-in mechanism are arranged on the second installation platform 4, and the rubber ring 51 feeding mechanism and the transfer mechanism are arranged on the first installation platform 3.

[0032] Furthermore, the inner cylinder 1 feeding mechanism includes an inner cylinder support frame 5 arranged on the lower surface of the first installation platform 3. A positioning column 6 and a ball screw 7 are arranged on the inner cylinder support frame 5. A motor 8 for driving the ball screw 7 to rotate is arranged on the inner cylinder support frame 5. It also includes an inner cylinder support plate 9 slidably connected to the positioning column 6. The inner cylinder support plate 9 is threadedly connected to the ball screw 7. A notch 10 for the upward movement of the inner cylinder 1 is opened on the upper surface of the first installation platform 3.

[0033] When placing the inner cylinder 1, first drive the ball screw 7 to rotate through the first motor 8. Through the threaded connection between the ball screw 7 and the inner cylinder support plate 9 and the sliding connection with the positioning column 6, the inner cylinder support plate 9 can be driven to move downward along the positioning column 6, so that the inner cylinder support plate 9 moves to the bottom of the positioning column 6. Then turn off the first motor 8. Next, place the inner cylinder 1 on the positioning column 6. The upper end of the positioning column 6 is provided with a rounded edge to facilitate the placement of the inner cylinder 1 on the positioning column 6. At the same time, the inner diameter of the inner cylinder 1 is slightly larger than that of the positioning column 6, so that the inner cylinder 1 can be placed on the positioning column 6 relatively conveniently. The inner diameter of the inner cylinder 1 is 160 mm, and the outer diameter of the positioning column 6 is 158 mm. After the placement of the inner cylinder 1 is completed, in order to facilitate the transfer mechanism to transfer the inner cylinder 1 on the positioning column 6, it is necessary to control the first motor 8 to start, drive the ball screw to rotate through the first motor 8, and drive the inner cylinder support plate 9 to move upward. Push the inner cylinder 1 to move upward along the positioning column 6 through the inner cylinder support plate 9, so that the transfer mechanism can clamp and transfer the inner cylinder 1 on the positioning column 6. During this process, the inner cylinder support plate 9 is always located inside the positioning column 6. When the inner cylinder support plate 9 moves upward to the highest position, the upper surface of the inner cylinder support plate 9 is located below the positioning column 6, and the distance between the two is 50 mm to ensure that the inner cylinder 1 will not be severely skewed due to vibration.

[0034] Further, the outer cylinder 2 placement mechanism includes an outer cylinder placement plate 11. The outer cylinder placement plate 11 is arranged on the second installation platform 4 and is rotatably connected to the second installation platform 4. A second motor 12 for driving the outer cylinder placement plate 11 to rotate is arranged on the second installation platform 4. A plurality of groups of positioning mechanisms are arranged on the outer cylinder placement plate 11. The positioning mechanisms are arranged in a circumferential array on the outer cylinder placement plate 11. The positioning mechanism includes a core cylinder 13 fixed on the outer cylinder placement plate 11. Four elastic pressing plates 14 are uniformly arranged on the outer surface of the core cylinder 13. The pressing plate 14 has a fixing part, a connecting part and a pressing part. The fixing part of the pressing plate 14 is installed on the outer surface of the core cylinder 13. The connecting part is inclined and used to connect the fixing part and the pressing part. An elastic backing plate 15 is arranged on the outer surface of the pressing part. The outer surface of the backing plate 15 is set to be arc-shaped. A spring 16 is arranged between the bottom side of the pressing part and the outer surface of the core cylinder 13.

[0035] When the pressing plate 14 is not under pressure, the pressing part of the pressing plate 14 is in an inclined state, and at the same time, the spring 16 is in an extended state. The states of the four pressing plates 14 are the same. When placing the outer cylinder 2, the lower end of the outer cylinder 2 will contact the connecting part on the pressing plate 14, and continuously squeeze the pressing part through the connecting part of the pressing plate 14. After being squeezed, the pressing part will move in the reverse direction of the core cylinder 13, and at the same time, the spring 16 is compressed. When the lower end of the outer cylinder 2 contacts the upper surface of the outer cylinder placement plate 11, at this time, the pressing part in the pressing plate 14 is perpendicular to the outer cylinder placement plate 11, and at the same time, the outer surface of the backing plate 15 is attached to the inner surface of the outer cylinder 2. The backing plate 15 is made of silica gel. By arranging the four pressing plates 14, the spring 16 and the backing plate 15, the center line of the outer cylinder 2 placed on the outer cylinder placement plate 11 can be made to coincide with the central axis of the core cylinder 13, and the coincidence error between the two is less than 0.5 mm. After all the outer cylinders 2 are placed, the outer cylinder placement plate 11 can be driven to rotate by the second motor 12, so as to drive the position of the outer cylinder 2 on the outer cylinder placement plate 11 to change.

[0036] Further, the rubber ring 51 feeding mechanism includes a rubber ring placement plate 17, which is arranged on the first installation platform 3 and rotatably connected to the first installation platform 3. A third motor 18 for driving the rubber ring placement plate 17 to rotate is arranged on the first installation platform 3. A number of stepped placement grooves 19 for placing the rubber ring 51 are formed on the rubber ring placement plate 17. When the rubber ring 51 is placed in the placement groove 19, the upper surface of the rubber ring 51 protrudes from the upper surface of the placement groove 19. The placement grooves 19 are arranged in a circumferential array on the rubber ring placement plate 17. A placement rack 20 is arranged on the first installation platform 3 and on the side of the rubber ring placement plate 17. A storage cylinder 21 is arranged on the placement rack 20. A notch is arranged on the side of the storage cylinder 21. The lower end surface of the storage cylinder 21 is located above the placement groove 19, and the distance between the lower end surface of the storage cylinder 21 and the upper surface of the placement groove 19 is less than the height of the rubber ring 51 when placed flat.

[0037] The inner diameter of the rubber ring 51 is smaller than the minimum inner diameter of the placement groove 19, and the maximum outer diameter of the placement groove 19 is larger than the outer diameter of the rubber ring 51, so that the rubber ring 51 can be easily placed into the placement groove 19. Before placing the rubber ring 51 into the placement groove 19, first stack multiple rubber rings 51 neatly in the storage cylinder 21, and then drive the rubber ring placement plate 17 to rotate through the third motor 18. The angle of each rotation of the rubber ring placement plate 17 is 60°. During the rotation of the rubber ring placement plate 17, when the placement groove 19 moves below the storage cylinder 21, under the action of the self-gravity of the rubber ring 51, the rubber ring 51 in the storage cylinder 21 can naturally fall into the placement groove 19. Only one rubber ring 51 can fall into each placement groove 19 each time. After one rubber ring 51 falls into the placement groove 19, control the rubber ring placement plate 17 to rotate through the third motor 18 to move the next placement groove 19 below the storage cylinder 21, so that the rubber ring 51 in the storage cylinder 21 continues to fall into the placement groove 19. And when the rubber ring placement plate 17 rotates, it can only transfer the rubber ring 51 that has fallen into the placement groove 19 out, and cannot transfer the rubber ring 51 that has not entered the placement groove 19 out, so as to prevent multiple rubber rings 51 from entering the placement groove 19 at the same time.

[0038] Further, the transfer mechanism includes a mounting frame 22. The mounting frame 22 is arranged on the first mounting platform 3 and is rotationally connected to the first mounting platform 3. A fourth motor 23 for driving the mounting frame 22 to rotate is arranged on the first mounting platform 3. A first fixed rod 24 and a second ball screw 25 are arranged on the mounting frame 22. A fifth motor 26 for driving the second ball screw 25 to rotate is arranged on the mounting frame 22. A first sliding seat 27 is threadedly connected to the second ball screw 25. The first sliding seat 27 is slidably connected to the first fixed rod 24. An extension plate 28 is arranged on one side of the first sliding seat 27. A side frame 29 is arranged on one side of the first sliding seat 27. The side frame 29 is rotationally connected to the first sliding seat 27. Synchronous wheels 30 are arranged on one side of both the side frame 29 and the extension plate 28. The two synchronous wheels 30 are driven by a synchronous belt 31. A sixth motor 32 for driving the synchronous wheel 30 to rotate is arranged on the extension plate 28. A third ball screw 33 with two externally threaded portions having opposite helix directions is arranged inside the side frame 29. A seventh motor 34 for driving the third ball screw 33 to rotate is arranged on the side frame 29. Two second sliding seats 35 are slidably connected inside the side frame 29. A side plate 36 is arranged on the side portion of the second sliding seat 35. A compressible clamping block 37 is arranged on the side plate 36. The inner side of the clamping block 37 is formed into an arc shape.

[0039] After completing the preparation work for placing the rubber ring 51, the inner cylinder 1, and the outer cylinder 2, the assembly work of the inner cylinder 1 and the outer cylinder 2 is started. First, the motor four 23 is controlled to rotate the mounting frame 22, so that the two clamping blocks 37 move above the notch 10. At this time, the two clamping blocks 37 are respectively located on both sides of the notch 10. Then, the motor four 23 is turned off. Next, the motor five 26 is started, and the ball screw two 25 is driven to rotate by the motor five 26. Through the threaded connection between the ball screw two 25 and the slider one 27, and the sliding connection between the fixed rod one 24 and the slider one 27, the two clamping blocks 37 are driven to move downward. At this time, the distance between the lower end of the clamping block 37 and the notch 10 is shortened to 50 mm. Then, the motor five 26 stops working. Next, the motor one 8 is started, and the ball screw one 7 is driven to rotate by the motor one 8, driving the inner cylinder support plate 9 to move upward along the positioning column 6 and pushing the inner cylinder 1 on the positioning column 6 upward. When the inner cylinder support plate 9 moves upward to the target position, the motor one 8 stops acting. At this time, the inner cylinder 1 is located between the two clamping blocks 37. At the same time, the two annular protrusions on the inner cylinder 1 are respectively located above and below the clamping blocks 37. Then, the motor seven 34 is started, and the ball screw three 33 is driven to rotate by the motor seven 34. Then, through the threaded connection between the ball screw three 33 and the two sliders two 35, the distance between the two sliders two 35 is shortened, and at the same time, the distance between the two side plates 36 and the two clamping blocks 37 is shortened. The clamping block 37 is made of silicone material. When the distance between the two clamping blocks 37 is shortened, the clamping and fixing of the inner cylinder 1 can be realized. When the two clamping blocks 37 complete the clamping and fixing of the inner cylinder 1, the motor seven 34 stops acting. Then, the motor five 26 is started, driving the two clamping blocks 37 to move upward, and at the same time driving the clamped inner cylinder 1 to move upward, so that the lower end of the inner cylinder 1 completely moves above the rubber ring placement plate 17. Then, the motor five 26 stops acting. Next, the motor four 23 is started, driving the mounting frame 22 to rotate 90°. Subsequently, the motor four 23 stops acting. At this time, the placement groove 19 is located directly below the inner cylinder 1 clamped by the two clamping blocks 37. Then, the motor five 26 is started, and the two clamping blocks 37 are driven to move downward by the motor five 26, and the inner cylinder 1 is driven to move downward, so that the lower end of the inner cylinder 1 passes through the middle of the rubber ring 51. Since it is easy for the clamping block 37 to slide relative to the inner cylinder 1, the motor five 26 needs to control the clamping block 37 to move downward to a predetermined height, that is, the lower end of the clamping block 37 contacts the upper surface of the annular protrusion below the inner cylinder 1. Through the abutment between the clamping block 37 and the protrusion, the inner cylinder 1 can be stably pushed downward, so that the rubber ring 51 can be installed on the inner cylinder 1. When the rubber ring 51 is installed on the inner cylinder 1, the rubber ring 51 is located below the protrusion on the inner cylinder 1, and at this time, the upper surface of the rubber ring 51 contacts the lower surface of the protrusion.

[0040] After the installation of a single rubber ring 51 is completed, start the fifth motor 26. The fifth motor 26 drives the clamping block 37 and the inner cylinder 1 to move upward. When the clamping block 37 and the inner cylinder 1 move upward by a certain height, the fifth motor 26 stops operating. Then start the sixth motor 32. Through the transmission of the sixth motor 32, the synchronous pulley 30 and the synchronous belt 31, the side frame 29 is driven to rotate 180°, so that the two clamping blocks 37 and the inner cylinder 1 rotate 180° simultaneously. At this time, there is no rubber ring 51 at the lower end of the inner cylinder 1. When the inner cylinder 1 is adjusting its position, the third motor 18 drives the rubber ring placement plate 17 to rotate 60°, so that the placement groove 19 with the rubber ring 51 placed in it moves back to the position of the previous rubber ring 51 that has just been used up. Then, through the fifth motor 26, the clamping block 37 and the inner cylinder 1 are controlled to move downward, so that the rubber ring 51 is sleeved on the lower end of the inner cylinder 1 again. When rubber rings 51 are sleeved on both ends of the inner cylinder 1, through the fifth motor 26, the inner cylinder 1 is controlled to move upward by a certain height, so that the horizontal height of the lower end of the inner cylinder 1 is higher than the horizontal height of the upper end of the outer cylinder 2 placed on the outer cylinder placement plate 11. Then, through the fourth motor 23, the installation frame 22 is controlled to rotate 180°, so that the inner cylinder 1 rotates above the outer cylinder 2. Then, through the fifth motor 26, the clamping block 37 and the inner cylinder 1 are driven to move downward. Through the extrusion force, the rubber ring 51 at the lower end of the inner cylinder 1 and the inner cylinder 1 enter the interior of the outer cylinder 2. When the inner cylinder 1 moves downward to the maximum distance under the action of the fifth motor 26, the pressing part of the pressing plate 14 enters the interior of the inner cylinder 1 and forms a support for the inner cylinder 1. Then, through the seventh motor 34, the distance between the two clamping blocks 37 is increased. At the same time, through the fifth motor 26, the clamping block 37 is driven to move upward. Then, through the fourth motor 23, the installation frame 22 is driven to rotate reversely by 270°, so that the clamping block 37 moves back to the position of the notch 10 to facilitate the clamping of a new inner cylinder 1.

[0041] Further, the pressing mechanism includes a vertical frame 38 provided on the second installation platform 4. A second fixed rod 39 and a fourth ball screw 40 are provided on the vertical frame 38. A motor eight 41 for driving the fourth ball screw 40 to rotate is provided on the vertical frame 38. It also includes a third sliding seat 42 slidably connected to the second guide rod. The third sliding seat 42 is threadedly connected to the fourth ball screw 40.

[0042] Since the transfer mechanism cannot completely press the inner cylinder 1 with the rubber ring 51 into the outer cylinder 2, at this time, the motor eight 41 drives the ball screw four 40 to rotate. Then, through the threaded connection between the ball screw four 40 and the slider three 42, and the sliding connection between the fixed rod two 39 and the slider three 42, the slider three 42 is driven to move downward. By the downward movement of the slider three 42, the inner cylinder 1 is completely pressed into the outer cylinder 2. During the downward movement of the inner cylinder 1 in the outer cylinder 2, the inner cylinder 1 will contact the connecting part of the pressing plate 14 and squeeze the pressing part of the pressing plate 14. The inner cylinder 1 exerts a greater extrusion force on the connecting part, so that after the pressing plate 14 is bent, the contact area between the backing plate 15 on the pressing plate 14 and the inner wall of the inner cylinder 1 is significantly smaller than the contact area between the backing plate 15 and the inner surface of the outer cylinder 2. Relatively, the frictional force between the inner cylinder 1 and the backing plate 15 is reduced. Although the pressing plate 14 and the spring 16 are further squeezed, the force applied to the inner cylinder 1 after squeezing is smaller than the frictional force lost due to the reduction of the contact area. Therefore, when the inner cylinder 1 and the outer cylinder 2 are assembled, the assembled air cylinder can be relatively easily removed from the outer cylinder placement plate 11.

[0043] After the assembly of the inner cylinder 1, the outer cylinder 2 and the rubber ring 51 is completed, the motor eight 41 drives the slider three 42 to move upward to facilitate the subsequent pressing of the next inner cylinder 1 into the outer cylinder 2. At the same time, the motor two 12 drives the outer cylinder placement plate 11 to rotate 60° to facilitate the assembly of the new inner cylinder 1 and the new outer cylinder 2.

[0044] Further, a through groove 43 is provided on the slider three 42. The upper end of the through groove 43 is flared and rounded. A number of grooves are provided on the through groove 43. A pressing block 44 is rotatably connected inside the groove. A limiting block 45 is provided at the upper end of the pressing block 44. A positioning block 46 is provided inside the groove. A through hole is provided inside the positioning block 46. An elastic member 47 is further included. One end of the elastic member 47 is provided with a stop block 48. The other end of the elastic member 47 passes through the through hole and is fixedly connected to the limiting block 45. An extension block 49 is provided on the lower side of the pressing block 44. A guiding plate 50 is provided on the lower surface of the extension block 49.

[0045] Before inserting the inner cylinder 1 into the outer cylinder 2 through the clamping block 37, first drive the third sliding seat 42 to move downward by the eighth motor 41, so that the distance between the lower surface of the third sliding seat 42 and the upper surface of the outer cylinder 2 placed on the outer cylinder placement plate 11 is 20 mm. Then drive the inner cylinder 1 in the clamping block 37 to rotate 180° by the fourth motor 23, so that the inner cylinder 1 moves to directly above the outer cylinder 2. Then control the inner cylinder 1 to move downward by the fifth motor 26. During the downward movement of the inner cylinder 1, the lower end of the inner cylinder 1 will first contact the surface of the extension block 49, and during continuous downward pressing, it will push the pressing block 44 to flip. When the pressing block 44 rotates 90°, the extension block 49 will abut against the stop block 48, thereby restricting the pressing block 44 from continuing to rotate. Then, through the fifth motor 26 and the eighth motor 41, control the third sliding seat 42 and the inner cylinder 1 to move downward simultaneously and at the same speed. Through the provided guide plate 50, the upper end of the outer cylinder 2 can be limited and fixed, so as to facilitate the inner cylinder 1 to be stably inserted into the outer cylinder 2. When the fifth motor 26 drives the inner cylinder 1 to move downward to the lowest position, the clamping block 37 releases the clamping of the inner cylinder 1, and then the fifth motor 26 drives the clamping block 37 to move upward. Then drive the clamping block 37 to move to the position of the notch 10 by the fourth motor 23. At the same time, drive the third sliding seat 42 to move upward by the eighth motor 41. When the extension block 49 is completely separated from the inner cylinder 1, under the action of the elastic member 47, the limiting block 45 abuts against the positioning block 46, restricting the further flipping of the stop block 48. Then drive the third sliding seat 42 to move downward by the eighth motor 41. When the upper end of the inner cylinder 1 contacts the lower surface of the extension block 49, due to the abutment of the limiting block 45 and the positioning block 46, the inner cylinder 1 can be continuously pushed vertically downward by the extension block 49 until the inner cylinder 1 is completely assembled into the outer cylinder 2.

[0046] Due to the limitation of multiple stop blocks 48 and extension blocks 49, it can play a guiding role for the inner cylinder 1, so that the lower end of the inner cylinder 1 is always located at the center of the through groove 43, ensuring that the lower end of the inner cylinder 1 can effectively enter the outer cylinder 2.

[0047] A bottom plate 52 is provided on each extension block 49. The bottom plates 52 on the six extension blocks 49 enclose a ring, and there is a gap between adjacent two bottom plates 52 to facilitate the flipping of the bottom plates 52 without being affected. When the inner cylinder 1 is pushed downward by the extension block 49, the six bottom plates 52 can cover as much as possible the upper end of the inner cylinder 1 and the rubber ring 51 sleeved on the upper end of the inner cylinder 1. Thus, when the rubber ring 51 at the upper end of the inner cylinder 1 is pressed into the outer cylinder 2, the force exerted by the bottom plate 52 on the rubber ring 51 is relatively uniform, so that the rubber ring 51 can stably enter the outer cylinder 2. The bottom plate 52 is made of metal stainless steel.

[0048] A vibration motor can be provided on the placement rack 20 to facilitate the stable delivery of the rubber rings 51 in the storage cylinder 21 into the placement groove 19.

[0049] The cooperation between the two synchronous pulleys 30 and the synchronous belt 31 can be replaced by the meshing transmission of two gears.

[0050] In the present invention, the actions of each motor can be controlled by setting distance sensors, angle sensors, time relays, and a PLC control system.
