Description

Technical Field

[0001] The present invention relates to the technical field of equipment related to the anti-corrosion process of steel pipes, and particularly relates to a steel pipe sticker device. Background Art

[0002] According to the anti-corrosion process of steel pipe enterprises, it is required to paste kraft paper tapes with a width of 100 mm - 160 mm on the outer wall of the pipe ends of steel pipes before applying anti-corrosion coatings.

[0003] Currently, this process is entirely manually pasted, and its operation process is as follows:

[0004] 1. Determine the tape length according to the diameter of the steel pipe and cut the kraft paper tape;

[0005] 2. Heat the adhesive;

[0006] 3. Use a brush to apply the adhesive to the kraft paper tape;

[0007] 4. Wind the kraft paper tape coated with the adhesive around the outer circumference of the pipe end of the steel pipe, and gently press the tape by hand to make it fit tightly, flatly and firmly with the outer surface of the steel pipe.

[0008] There are the following disadvantages in manually pasting kraft paper tapes:

[0009] 1. One person is arranged for each end of the steel pipe, with a total of 2 people, consuming labor;

[0010] 2. Manually applying the adhesive is uneven;

[0011] 3. Manually winding the tape is time-consuming and laborious. Especially for steel pipes with a larger diameter, the human arm cannot reach the upper half of the outer circumference of the steel pipe, so it is impossible to apply pressure to the tape on the upper half of the steel pipe to make it flat and firm;

Specific embodiments

[0048] The embodiments of the technical solution of the present invention will be described in detail below with reference to the drawings. The following embodiments are only used to illustrate the technical solution of the present invention more clearly, so they are only examples and cannot be used to limit the protection scope of the present invention.

[0049] It should be noted that unless otherwise specified, the technical terms or scientific terms used in this application should have the ordinary meanings understood by those skilled in the art to which the present invention belongs.

[0050] As Figure 1 and Figure 2As shown, this embodiment provides a steel pipe sticker device for pasting kraft paper tape on the outer periphery of the pipe end of a steel pipe 1, including a steel pipe rotating device 2 and a sticker device. The steel pipe rotating device 2 is used to support the steel pipe 1 and drive the steel pipe 1 to rotate around its own axis. Specifically, the steel pipe rotating device 2 includes an active roller 21 and a driven roller 22. The active roller 21 is driven by a motor to rotate, thereby driving the steel pipe 1 to rotate. The driven roller 22 is used to support the steel pipe 1 and can rotate synchronously under the action of the friction force of the steel pipe 1. It can be seen that the steel pipe rotating device 2 of this embodiment has two functions, one is to support the steel pipe 1, and the other is to drive the steel pipe 1 to rotate.

[0051] The sticker device includes a base 3, and a running mechanism is provided at the bottom of the base 3. The running mechanism drives the base 3 to move along a track 31. The length direction of the track 31 is consistent with the axial direction of the steel pipe 1. Specifically, the running mechanism includes two pairs of wheels 32 installed at the bottom of the base 3. The wheels 32 are adapted to the track 31. One pair of wheels is a driving wheel, and the other pair of wheels is a driven wheel. The driving wheel is driven to rotate by a motor and a reducer, and the driving wheel is connected to the reducer through a chain transmission. The motor rotates, and the driving wheel is driven to rotate through the chain, thereby driving the base 3 to move along the track 31.

[0052] Further, refer to Figure 3 The base 3 includes a bottom plate 33 and a panel 34, the bottom plate 33 and the panel 34 are connected by a lifting mechanism, and the bottom of the bottom plate 33 is provided with the above-mentioned walking mechanism. Figure 4 The lifting mechanism includes a driving motor 35, the output shaft of the driving motor 35 is connected to the input shaft of the first commutator 36, the two output shafts of the first commutator 36 are connected to the input shafts of the two second commutators 37, the output shafts of the two second commutators 37 are connected to the input shafts of the four lifters 38, and the four lifters 38 are arranged in a matrix. The lifters 38 are specifically screw lifters, one end of which is rotatably connected to a flange, and the output shafts of the four lifters 38 are connected to the panel 34 through the flange to drive the panel 34 to move relative to the bottom plate 33. In addition, in order to facilitate the smooth installation of the lifters 38, a through hole is provided at the position of the bottom plate 33 corresponding to the lifters 38, and the lower end of the output shaft of the corresponding lifter 38 is inserted into the through hole. In this embodiment, the panel 34 is connected to the surrounding plates 39 on all sides, and the four surrounding plates 39 are enclosed to form a receiving cavity for accommodating and protecting the lifting mechanism, and there is a gap between the inner periphery of the bottom plate 33 and the surrounding plates 39 to facilitate the smooth lifting of the panel 34. The lifting mechanism of this embodiment uses a motor and three 90-degree angle gear boxes to synchronously drive four lifts 38 to rise and fall synchronously, so as to achieve smooth movement of the panel 34.

[0053] refer to Figure 1 and Figure 5, an operation platform 4 is provided at the top of the base 3. The operation platform 4 includes a substrate 41 slidably connected to the panel 34 and a platform bracket 42 fixedly installed on the top of the substrate 41. The substrate 41 is slidably connected to the panel 34 in the axial direction of the steel pipe 1. Specifically, the substrate 41 and the panel 34 are slidably connected through a guide rail slider mechanism. And the substrate 41 and the panel 34 are connected by a telescopic cylinder 43. The telescopic cylinder 43 is a piston cylinder such as a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder. In this embodiment, the telescopic cylinder 43 is preferably a pneumatic cylinder. Its cylinder barrel end is fixedly connected to the panel 34, and its cylinder rod end is fixedly connected to the substrate 41. And the telescopic cylinder 43 and the steel pipe 1 are respectively located on both sides of the operation platform 4.

[0054] Reference Figure 1 , Figure 6 and Figure 7, a wheel abutting device 5 is provided on the top of the platform bracket 42, and the wheel abutting device 5 is used to abut against the end face of the steel pipe 1. Specifically, the wheel abutting device 5 includes a wheel abutting bracket 51 fixedly connected to the platform bracket 42. A vertical plate 52 and a first connecting member 53 are hinged to the top of the wheel abutting bracket 51, and there is a distance between the hinge points of the two. A second connecting member 54 is hinged to the vertical plate 52, and the second connecting member 54 is connected to the first connecting member 53 through an adjusting member 55. The adjusting member 55 is a pipe fitting, and a first internal thread 551 and a second internal thread 552 are respectively provided at both ends of its inner circumference. The first internal thread 551 and the second internal thread 552 have opposite helix directions. There is also a smooth hole section 553 in the inner circumference of the adjusting member 55, and the first internal thread 551 and the second internal thread 552 are respectively located on both sides of the smooth hole section 553. First external threads and second external threads are respectively provided on the outer circumferences of the first connecting member 53 and the second connecting member 54. The first external thread is screwed with the first internal thread 551, and the second external thread is screwed with the second internal thread 552. Moreover, the length of the first external thread is greater than the length of the first internal thread 551, and the length of the second external thread is greater than the length of the second internal thread 552. Two mounting plates 56 are welded in parallel at intervals on the side of the vertical plate 52 facing the steel pipe 1. An installation shaft 57 is connected between the two mounting plates 56. A collision wheel 58 is coaxially rotatably connected to the outer circumference of the installation shaft 57 through a bearing, so that the collision wheel 58 can rotate around the installation shaft 57. The wheel abutting device 5 of this embodiment can adjust the axial direction of the collision wheel 58. In practice, for steel pipes 1 with different diameters, the adjusting member 55 can be rotated to drive the first connecting member 53 and the second connecting member 54 to extend or retract synchronously, so as to adjust the inclination angle of the vertical plate 52 relative to the wheel abutting bracket 51, and further adjust the axial direction of the collision wheel 58, so that the axial direction of the collision wheel 58 is consistent with the radial direction of the steel pipe 1. When adjusting, a length scale or a tape measure can be added to compare whether the projection of the axis of the collision wheel 58 on the end face of the steel pipe passes through the center of the end face of the steel pipe. Further, a first nut 531 is screwed on the outer circumference of the first external thread, and a second nut 541 is also screwed on the outer circumference of the second external thread. The first nut 531 and the second nut 541 are respectively located on both sides of the adjusting member 55. After the angle of the collision wheel 58 is adjusted in place, the first nut 531 and the second nut 541 can be tightened to lock the adjusting member 55 and prevent the angle change of the collision wheel 58 caused by the accidental rotation of the adjusting member 55.

[0055] On the upper part of the above-mentioned operating platform 4, a paper feeding mechanism 6, a paper cutting mechanism 7 and a gluing mechanism 8 are successively arranged along the conveying direction of the paper tape. The paper feeding mechanism 6 is used for tensioning and guiding the paper tape. The paper cutting mechanism 7 is used for cutting the paper tape and adsorbing the leading end of the cut paper tape. The gluing mechanism 8 is used for applying glue on the surface of the paper tape. A roller assembly 9 and a first driving mechanism 91 for driving the roller assembly 9 to move along the conveying direction of the paper tape are also arranged on the operating platform 4. The roller assembly 9 is used for pulling the leading end of the paper tape and pasting the leading end of the paper tape on the outer periphery of the pipe end of the steel pipe 1, and for pressing against the outer periphery of the steel pipe 1 when the steel pipe 1 rotates to paste the paper tape.

[0056] During the production of steel pipes, minor diagonal cuts may occur, or due to the irregular edges of the raw material steel plates, the formed steel pipes may not be straight in the axial direction. During the process of pasting kraft paper tapes, if the kraft paper tapes do not follow the movement of the end faces of the steel pipes, it will cause the kraft paper tapes to cross the coating standard line, resulting in the coating material not being able to completely coat the outer walls of the steel pipes, leading to the disqualification of the entire steel pipe coating. In this regard, the telescopic cylinder 43 and the roller device 5 in this embodiment work together to enable the kraft paper tapes to follow the movement of the end faces of the steel pipes during the pasting process. The specific following principle is as follows: According to the diameter of the steel pipe to which the paper tape is to be pasted, the elevator 38 is used to adjust the position of the panel 34 in the vertical direction, and the rod end of the telescopic cylinder 43 is controlled to extend autonomously to the limit position. Then, the motor of the traveling mechanism of the base 3 is started to drive the wheels 32 to move forward along the direction of the track 31 and gradually approach the steel pipe 1. During this process, the operating platform 4 moves forward synchronously with the base 3; after the collision wheel 58 contacts the pipe end of the steel pipe 1, the motor of the traveling mechanism of the base 3 continues to work to drive the base 3 to continue moving forward. Since the weight of the steel pipe is generally about 10 tons or more, the reverse force exerted by the pipe end of the steel pipe 1 on the collision wheel 58 will force the rod end of the telescopic cylinder 43 to retract, that is, at this time, the operating platform 4 retreats relative to the base 3. When the rod end of the telescopic cylinder 43 retracts to half of its stroke position, the motor of the traveling mechanism of the base 3 is controlled to stop working, and the base 3 stops moving forward. At this time, the compressed telescopic cylinder 43 will exert a force on the operating platform 4, causing the operating platform 4 to have a tendency to move in the direction of the steel pipe 1. During the process of winding the kraft paper tape, let the initial contact surface between the pipe end of the steel pipe 1 and the collision wheel 58 be the initial plane. Then, as the steel pipe 1 rotates, if the real-time contact surface of the pipe end of the steel pipe 1 deviates from the initial plane in the first direction (the direction away from the operating platform 4), the operating platform 4 will move in the first direction under the drive of the rod end of the telescopic cylinder 43, so that the collision wheel 58 and the pipe end of the steel pipe 1 remain in contact; if the real-time contact surface of the pipe end of the steel pipe 1 deviates from the initial plane in the second direction (the direction towards the operating platform 4), the steel pipe 1 will drive the entire operating platform 4 to move in the second direction through the collision wheel 58, and the rod end of the telescopic cylinder 43 is forced to retract. During this process, the collision wheel 58 always remains in contact with the pipe end of the steel pipe 1. It can be seen that under the combined action of the rod end in the energy storage state and the steel pipe weighing more than 10 tons, the function of the operating platform 4 following the real-time end face of the steel pipe 1 can be realized, enabling the kraft paper tape to track the changes in the edge of the end of the steel pipe 1, adjust the transmission direction of the kraft paper tape in real time, correct the possible displacement during the conveying of the kraft paper tape, and prevent the occurrence of large wrinkles. In this embodiment, deliberately controlling the rod end of the telescopic cylinder 43 to retract to half of its stroke position is to ensure that there is sufficient margin for the extension and retraction of its rod end.

[0057] Reference Figure 1 and Figure 8, the above paper feeding mechanism 6 includes a paper feeding support 61, an adjusting roller set, and three guide rollers 62 arranged vertically and staggeredly. Among them, the paper feeding support 61 is installed on the operation platform 4, and the guide rollers 62 are located in front of the adjusting roller set in the paper tape conveying direction. The rotating shafts of the three guide rollers 62 are fixedly installed on the paper feeding support 61, and there is a paper feeding gap between two adjacent guide rollers 62. The above adjusting roller set includes two fixed rollers 63 and two movable rollers 64 arranged vertically between the two fixed rollers 63. The rotating shafts of the two fixed rollers 63 are fixedly installed on the paper feeding support 61, and the axes of the two fixed rollers 63 are on the same horizontal plane. The movable rollers 64 are located below the fixed rollers 63. There is a paper feeding gap between the two movable rollers 64, and the rotating shafts of the two movable rollers 4 are fixedly installed on the adjusting support 65. The adjusting support 65 is slidably connected to the paper feeding support 61 in the vertical direction through a guide rail slider structure. In this embodiment, after the paper tape is output from the paper tape roll, it is tensioned by the adjusting roller set. When the paper tape passes through the adjusting roller set, it first bypasses the top of a fixed roller 63, then passes downward through the paper feeding gap between the two movable rollers 64, and finally turns upward to bypass the top of another fixed roller 63. The paper tape output from the adjusting roller set is conveyed to the paper cutting mechanism 7 along the paper feeding gap between two adjacent guide rollers 62. Since the movable rollers 64 are slidably connected to the paper feeding support 61 through the adjusting support 65, when the paper tape is loose, the movable rollers 64 will slide downward under the action of gravity until the tension of the paper tape and the gravity of the movable rollers 64 are balanced; when the paper tape is tight, the movable rollers 64 will slide upward under the action of the tension of the paper tape to overcome their own gravity until the tension of the paper tape and the gravity of the movable rollers 64 are balanced. In addition, the guide rollers 62 can play a role in guiding and correcting the deviation, so that the paper tape can be conveyed to subsequent paper cutting mechanisms 7, gluing mechanisms 8, etc. in the correct posture.

[0058] Further, referring to Figure 8 , Figure 9 and Figure 10, the above paper feeding mechanism 6 further includes a length measuring mechanism 66 for measuring the conveying length of the paper tape. The length measuring mechanism 66 includes a length measuring bracket, which specifically includes a mounting seat 661 fixedly connected to the paper feeding bracket 61 and a shaft portion 662 fixedly connected to the mounting seat 661. The length measuring mechanism 66 further includes a swing piece 663, a length measuring portion and a return spring 664. The above length measuring portion includes an encoder 665 and a roller 666. The outer diameter of the roller 666 is larger than the outer diameter of the encoder 665. The roller 666 is coaxially and fixedly sleeved on the outer periphery of the rotating shaft of the encoder 665, so that the roller 666 and the rotating shaft of the encoder 665 can rotate synchronously. Both ends of the above swing piece 663 are respectively provided with a first connection hole and a second connection hole. The first connection hole is movably sleeved on the outer periphery of the shaft portion 662. The housing of the encoder 665 is fixedly connected to the swing piece 663, and the rotating shaft of the encoder 665 passes through the second connection hole and is fixedly connected to the roller 666. The rotating shaft of the encoder 665 can rotate in the second connection hole. Both ends of the above return spring 664 are respectively connected to the swing piece 663 and the shaft portion 662. The roller 666 can be tightly abutted against the top of the speed measuring roller under the action of the return spring 664. The speed measuring roller is specifically a fixed roller 63 close to the guide roller 62. The top of the fixed roller 63 is wound with a paper tape, and the paper tape will be clamped between the roller 666 and the corresponding fixed roller 63. During the paper tape conveying process, the roller 666 will rotate under the action of friction, and then drive the rotating shaft of the encoder 665 to rotate. According to the pulse information of the encoder 665, the conveying length of the paper tape can be calculated, and this calculated information can guide the paper cutting mechanism 7 to cut the paper tape at an appropriate length. In this embodiment, an Omron encoder, model E6B2-CWZ5B, with 1000 pulses per revolution is selected. Let the radius of the roller 666 be R and the paper tape length be L. If the pulse value of the encoder 665 is N, then the paper tape length L can be calculated by the following formula:

[0059] L = 2πRN / 1000 = πRN / 500.

[0060] Further, referring to Figure 1 , Figure 11 and Figure 12, the steel pipe sticker device of the present invention further includes an unwinding mechanism 10 for conveying a paper tape to the paper feeding mechanism 6. The unwinding mechanism 10 includes an unwinding bracket 101. A traveling wheel 102 is provided at the bottom of the unwinding bracket 101, and a fixing part 103 is fixedly connected to the side of the unwinding bracket 101. The unwinding mechanism 10 further includes a follower part 104 slidably connected to the fixing part 103 in the vertical direction, and the follower part 104 is fixedly connected to the operation platform 4; the unwinding mechanism 10 further includes an air shaft 105 rotatably connected to the unwinding bracket 101. A paper tape roll 106 is sleeved on the outer periphery of the air shaft 105. One end of the air shaft 105 away from the paper tape roll 106 is in transmission connection with a second driving mechanism 107, and the second driving mechanism 107 is used to drive the air shaft 105 to rotate. In this embodiment, the second driving mechanism 107 includes a motor and a reducer connected to the output shaft of the motor, and the output shaft of the reducer is in transmission connection with the air shaft 105. Specifically, the fixing part 103 includes a linear bearing, and the follower part 104 includes a smooth shaft slidably connected to the linear bearing. When the operation platform 4 makes a lifting movement driven by the elevator 38, the follower part 104 and the operation platform 4 are lifted and lowered synchronously. At this time, the follower part 104 slides relative to the fixing part 103 in the vertical direction, and the relative sliding stroke of the follower part 104 and the fixing part 103 is greater than the lifting stroke of the operation platform 4. Therefore, the fixing part 103 will not be displaced in the vertical direction driven by the follower part 104, that is, the unwinding bracket 101 will not follow the operation platform 4 to be lifted and lowered synchronously. When the operation platform 4 moves forward or backward, the fixing part 103 will be displaced in the horizontal direction driven by the follower part 104, thereby driving the unwinding mechanism 10 to move forward or backward synchronously. In addition, during operation, the motor and the reducer of the second driving mechanism 107 can drive the air shaft 105 to rotate, realizing the automatic unwinding of the paper tape roll 106, and the released paper tape can be sent into the paper feeding mechanism 6 for tensioning and guiding; when needed, the operator can control the disassembly and installation of the paper tape roll 106 by controlling the air supply state of the air shaft 105.

[0061] Reference Figure 1 、 Figure 13 、 Figure 14 And Figure 15, the above paper cutting mechanism 7 includes a paper cutting bracket installed on the platform bracket 42. Specifically, the paper cutting bracket includes two parallel and spaced-apart support plates 71, which are respectively located at both ends of the platform bracket 42 in the width direction. A paper cutting knife 72 and a third driving mechanism 73 for driving the paper cutting knife 72 to move along the width direction of the platform bracket 42 are provided on the paper cutting bracket. Specifically, the third driving mechanism 73 is a guide rod cylinder. The two fixed ends of the guide rod cylinder are respectively fixedly connected to the tops of the two support plates 71, and the paper cutting knife 72 is fixedly connected to the movable end of the guide rod cylinder. Then, the third driving mechanism can drive the paper cutting knife 72 to reciprocate between the two support plates 71. A paper pressing member 74 is also connected to the paper cutting bracket. A first paper cutting groove 741 is provided through the paper pressing member 74. A paper tape adsorption device 742 is also provided on the paper pressing member 74. The paper tape adsorption device 742 is located behind the first paper cutting groove 741 in the paper tape conveying direction. The paper tape adsorption device 742 specifically includes two negative pressure suction cups. The adsorption ports of the negative pressure suction cups are arranged downward. The negative pressure suction cups are connected to a negative pressure generator (not shown in the figure) through electromagnetic valves to realize the on-off between the negative pressure suction cups and the negative pressure generator, and further realize the adsorption or release of the paper tape by the negative pressure suction cups. The above paper pressing member 74 can be lifted and lowered in the vertical direction under the drive of a fourth driving mechanism 75. Specifically, the fourth driving mechanism 75 includes two cylinders. The cylinder barrel ends of the two cylinders are respectively fixedly connected to the two support plates 71, and the cylinder rod ends of the two cylinders are respectively connected to both ends of the paper pressing member 74 in the length direction. A paper supporting member 76 for supporting the paper tape is also provided on the platform bracket 42. The paper supporting member 76 is made of ferromagnetic material. A second paper cutting groove 761 is provided through the paper supporting member 76. Both the second paper cutting groove 761 and the above first paper cutting groove 741 are arranged along the width direction of the platform bracket 42. In this embodiment, the paper supporting member 76 and the platform bracket 42 are slidably connected through a guide rail slider mechanism, so that the paper supporting member 76 can slide along the length direction of the platform bracket 42 under the drive of the roller assembly 9. Reference Figure 1 , a first limiting portion 421 and a second limiting portion 422 for limiting the extreme movement positions of the paper supporting member 76 are also provided on the platform bracket 42. The first limiting portion 421 and the second limiting portion 422 are respectively located at both ends of the platform bracket 42 in the length direction; when the paper supporting member 76 abuts against the first limiting portion 421, the second paper cutting groove 761 is exactly located directly below the first paper cutting groove 741. At this time, the paper pressing member 74 can be pressed tightly against the top of the paper supporting member 76 under the drive of the fourth driving mechanism 75, and the paper cutting knife 72 can cut the paper tape along the first paper cutting groove 741 and the second paper cutting groove 761 under the drive of the third driving mechanism 73; when the paper supporting member 76 abuts against the second limiting portion 422, there is no overlapping area in the horizontal plane projection between the paper supporting member 76 and the paper pressing member 74.

[0062] When it is necessary to cut the paper tape, the fourth driving mechanism 75 drives the paper pressing member 74 to move until the paper pressing member 74 presses tightly on the top of the paper supporting member 76, so that the paper tape is clamped between the paper pressing member 74 and the paper supporting member 76. At this time, the first paper cutting groove 741 is directly above the second paper cutting groove 761. Subsequently, the third driving mechanism 73 drives the paper cutter 72 to cut the paper tape along the first paper cutting groove 741 and the second paper cutting groove 761. The part of the paper tape aligned with the first paper cutting groove 741 and the second paper cutting groove 761 is the part to be cut. When cutting, both sides of the part to be cut of the paper tape are pressed tightly on the paper supporting member 76 by the paper pressing member 74, ensuring that the part to be cut of the paper tape is in a tensioned state, which is convenient for the paper cutter 72 to cut smoothly; in addition, the paper tape adsorption device 742 of the paper pressing member 74 is located behind the paper tape conveying direction relative to the first paper cutting groove 741, so that the leading end of the paper tape after cutting can be adsorbed and fixed by the paper tape adsorption device 742.

[0063] Reference Figure 1 、 Figure 16 and Figure 17, the above-mentioned glue application mechanism 8 includes a glue hopper 81 and a fifth driving mechanism 82 for adjusting the vertical position of the glue hopper 81. Specifically, the fifth driving mechanism 82 is a cylinder. The rod end of the cylinder is fixed to the top of two support plates 71, and the cylinder barrel end of the cylinder is connected to the glue hopper 81 to realize the adjustment of the vertical position of the glue hopper 81. The interior of the above-mentioned glue hopper 81 has a glue storage cavity. The top of the glue hopper 81 is open to form a glue inlet communicating with the glue storage cavity. The bottom of the glue hopper 81 is provided with a glue outlet communicating with the glue storage cavity, and the glue outlet is arranged along the length direction of the glue storage cavity. A glue application roller 83 is arranged in the glue outlet, and the axis direction of the glue application roller 83 is the same as the length direction of the glue outlet. Specifically, the glue application roller 83 includes a fixing member and a rotating part coaxially sleeved on the outer periphery of the fixing member. The above-mentioned rotating part includes a steel pipe fitting 831 and a rubber roller 832 attached to the outer periphery of the steel pipe fitting 831. The above-mentioned fixing member includes a roller shaft 833. A bearing is sleeved on the outer periphery of the roller shaft 833. The inner ring of the bearing is in interference fit with the outer periphery of the roller shaft 833, and the outer ring is in interference fit with the inner periphery of the steel pipe fitting 831, so that the rotating part can rotate relative to the fixing member. In addition, a spacer sleeve 834 is also sleeved on the outer periphery of the roller shaft 833, and the spacer sleeve 834 is used for positioning the bearing. Limiting grooves 811 are arranged at both ends of the glue hopper 81 in the length direction. The limiting grooves 811 are oblong holes arranged in the vertical direction. Both ends of the roller shaft 833 are respectively inserted into the two limiting grooves 811, and the part of the roller shaft 833 extending out of the limiting grooves 811 is provided with external threads for easy fixation by nuts. In addition, chutes are opened on the inner walls at both ends of the glue hopper 81 in the length direction. The chutes are arranged in the vertical direction, and the width of the chutes is adapted to the outer diameter of the rubber roller 832, and both ends of the rubber roller 832 are in contact with the bottom wall of the chutes; the chutes can play a guiding role for the glue application roller 83, thereby ensuring that the gap size between the outer periphery of the glue application roller 83 and the inner periphery of the glue outlet is the same on each cross-section of the glue application roller 83; in addition, the contact between the end of the rubber roller 832 and the bottom wall of the chute can ensure that the glue can only leak out from the side of the rubber roller 832 and will not leak out from the end of the rubber roller 832.

[0064] In this embodiment, the rotating part of the glue application roller 83 can rotate around the roller shaft 833 under the action of the tangential force, and the whole glue application roller 83 can move up and down in the limiting groove 811 under the action of its own gravity and the external force in the vertical direction. When the glue application roller 83 is in the lowest position relative to the limiting groove 811, the outer circumference of the glue applicator roller 832 is in sealing contact with the glue outlet to prevent the glue from leaking out; when the glue application roller 83 gradually moves upward from its lowest position, the gap between the glue applicator roller 832 and the glue outlet gradually increases, facilitating the leakage of the glue. Of course, when the glue application roller 83 is in the highest position relative to the limiting groove 811, the bottom of the glue application roller 83 still protrudes from the bottom of the glue hopper 81 to ensure that the glue application operation can still be carried out when the glue application roller 83 is in the highest position. When the sticker device of this embodiment works, when the paper supporting member 76 moves to abut against the first limiting portion 421 under the drive of the roller assembly 9, the glue application roller 83 is exactly above the paper supporting member 76. At this time, the fifth driving mechanism 82 drives the glue hopper 81 to descend until the glue application roller 83 abuts against the paper tape on the paper supporting member 76. The paper on the paper supporting member 76 will exert a vertically upward reaction force on the glue application roller 83, causing the glue application roller 83 to move upward along the limiting groove 811 until the force on the glue application roller 83 in the vertical direction is balanced. At this time, a certain gap will be formed between the glue applicator roller 832 and the glue outlet, and the glue in the glue hopper 81 will leak out from this gap. At the same time, as the paper tape is conveyed, the glue applicator roller 832 will rotate synchronously under the action of the friction force of the paper tape to facilitate evenly applying the leaked glue on the upper surface of the paper tape. In practice, the glue output can be adjusted by adjusting the height position of the glue hopper 81.

[0065] Reference Figure 1 、 Figure 5 and Figure 18, the above-mentioned idler assembly 9 is slidably connected to the substrate 41 in the paper tape conveying direction through a first driving mechanism 91, and the first driving mechanism 91 is specifically a linear slide table. The idler assembly 9 includes an idler bracket 92, which is installed on the slider of the first driving mechanism 91. A traction member 93 and a sixth driving mechanism 94 are installed on the idler bracket 92. The sixth driving mechanism 94 is a cylinder, its cylinder end is fixedly connected to the idler bracket 92, and its piston rod end is fixedly connected to a mounting bracket 95. Both ends of the mounting bracket 95 are rotatably connected to end plates 96, and two idlers 97 are rotatably installed between the two end plates 96. The idlers 97 are located behind the traction member 93 in the paper tape conveying direction. A paper tape adsorption portion 931 for adsorbing the lower surface of the leading end of the paper tape is provided at the top of the above-mentioned traction member 93. The paper tape adsorption portion 931 is specifically a negative pressure adsorption port arranged upward, and the negative pressure adsorption port is connected to a negative pressure generator (not shown in the figure) through a solenoid valve to realize the on-off of the negative pressure adsorption port and the negative pressure generator, and further realize the adsorption or release of the paper tape by the negative pressure adsorption port. In addition, a plurality of magnets are embedded at one end of the traction member 93 facing the paper cutting mechanism 7, so that the traction member 93 can be attracted to the paper supporting member 76 made of ferromagnetic material.

[0066] When pasting the kraft paper tape for the first time, the paper tape adsorption portion 931 of the traction member 93 generates negative pressure, so that the leading end of the kraft paper tape is adsorbed on the top of the traction member 93. The first driving mechanism 91 drives the idler assembly 9 to slide to its pasting position. At this time, the two idlers 97 are located directly below the steel pipe 1 (the sixth driving mechanism 94 is located directly below the steel pipe 1). During this process, the gluing mechanism 8 applies glue to the surface of the kraft paper tape. Then, the sixth driving mechanism 94 drives the idler 97 to move upward until it abuts against the end face of the steel pipe 1, and pastes the kraft paper tape on the outer circumference of the steel pipe 1. During this process, the negative pressure at the paper tape adsorption portion 931 is maintained. Then, the sixth driving mechanism 94 and the first driving mechanism 91 work simultaneously (the first driving mechanism 91 drives the idler assembly 9 to move forward in the paper tape conveying direction, and the sixth driving mechanism 94 drives the idler 97 to rise), driving the idler 97 to move simultaneously in the horizontal and vertical directions, forming a combined movement that rotates around the axis of the steel pipe 1, so as to facilitate the complete pasting of the leading end of the kraft paper tape on the outer circumference of the steel pipe 1. During this process, the paper tape adsorption portion 931 is disconnected from the negative pressure generator, and the negative pressure is released, so that the leading end of the paper tape can be successfully pasted. After pasting, the sixth driving mechanism 94 and the first driving mechanism 91 drive the idler assembly 9 to reset to its pasting position, so that the two idlers 97 support directly below the steel pipe 1 and abut against the end face of the steel pipe 1. At this time, the steel pipe rotating device 2 drives the steel pipe 1 to start rotating, and then drives the kraft paper tape to continue to wind around the outer circumference of the end of the steel pipe 1. During this process, the idler 97 always abuts against the outer circumference of the steel pipe 1, so that the kraft paper tape can be in close contact with the outer wall of the steel pipe 1, and the pasting effect is better.

[0067] During the process of pasting the kraft paper tape, the controller calculates the conveying length of the kraft paper tape based on the information fed back by the length measuring mechanism 66, and compares it with the length of the tape required for pasting the corresponding steel pipe. When the conveying length of the kraft paper tape reaches the requirement, the controller controls the driving roller 21 of the steel pipe rotating device to stop operating, causing the steel pipe 1 to pause rotating, and controls the fourth driving mechanism 75 to drive the paper pressing member 74 to move downward and press tightly against the top of the paper supporting member 76. At the same time, the tape adsorption device 742 on the paper pressing member 74 generates negative pressure and adsorbs on the upper surface of the tape. Subsequently, the third driving mechanism 73 drives the paper cutter 72 to quickly cut the tape; then, the controller controls the driving roller 21 of the steel pipe rotating device 2 to continue operating, driving the steel pipe 1 to continue rotating, so that the end of the front section of the tape can continue to wind around the outer periphery of the end of the steel pipe 1. At the same time, the fourth driving mechanism drives the paper pressing member to move upward, and the leading end of the cut tape will be lifted together under the negative pressure adsorption of the tape adsorption device 742.

[0068] After the front section of the tape is completely pasted, the sixth driving mechanism 94 drives the supporting roller 97 to move downward (to prevent its movement trajectory from interfering with the various mechanisms on the platform bracket 42). At the same time, the first driving mechanism 91 drives the supporting roller assembly to move in the direction of the paper cutting mechanism 7. During the movement, the traction member 93 engages with the end of the paper supporting member 76 and pushes the paper supporting member 76 to slide relative to the platform bracket 42 until the paper supporting member 76 abuts against the second limiting portion 422. At this time, the supporting roller assembly 9 is in its traction position, and the traction member 93 is exactly located directly below the tape adsorption device 742. Subsequently, the fourth driving mechanism 75 drives the paper pressing member 74 to move downward, causing the bottom of the tape adsorption device 742 to abut against the top of the traction member 93, and at the same time controlling the tape adsorption device 742 to disconnect from the negative pressure generator, and the tape adsorption portion 931 of the traction member 93 to communicate with the negative pressure generator, that is, controlling the negative pressure of the tape adsorption device 742 to be released, and the negative pressure of the tape adsorption portion 931 to be established, so that the leading end of the tape is smoothly transferred from the paper pressing member 74 to the traction member 93. Then, the first driving mechanism 91 drives the supporting roller assembly 9 to reset to its pasting position to perform the next round of tape leading end pasting operation; during this process, the paper supporting member 76 will move synchronously under the suction force of the traction member 93. After the paper supporting member 76 abuts against the first limiting portion 421, the traction member 93 separates from the paper supporting member 76 and continues to move towards its pasting position, while the paper supporting member 76 remains in its position. In this position, the second paper cutting groove 761 of the paper supporting member 76 is exactly located below the first paper cutting groove 741 of the paper pressing member 74, facilitating the cutting of the next round of tape.

[0069] Further, referring to Figure 1 and Figure 19A flipping device 11 is also provided on the substrate 41. When the roller assembly 9 is at its pasting position, the flipping device 11 is located between the roller assembly 9 and the paper cutting mechanism 7. The flipping device 11 includes a support plate 111 for supporting the paper tape and a seventh driving mechanism 112 for driving the support plate 111 to flip 90 degrees. The seventh driving mechanism 112 is specifically a flipping cylinder. The support plate 111 is connected to the movable part of the flipping cylinder. The support plate 111 can be driven by the seventh driving mechanism 112 to be in an avoidance position ( Figure 19 The solid line part) and a paper support position ( Figure 19 When the support plate 111 is in the paper supporting position, the support plate 111 is in a horizontal state; when the support plate 111 is in the avoidance position, the support plate 111 is in a vertical state, and the movement trajectories of the flipping device 11 and the roller assembly 9 do not interfere with each other. A plurality of through holes are arranged in a matrix on the support plate 111 to reduce the wind resistance when the support plate 111 is flipped.

[0070] Under normal conditions, the support plate 111 remains in its avoidance position, and after the paper cutting mechanism 7 cuts off the paper tape, the seventh driving mechanism 112 is controlled to drive the support plate 111 to flip to its paper supporting position. At this time, the support plate 111 can be used to support the end of the paper tape to prevent the end of the paper tape from falling to the ground; after the paper tape is completely attached to the outer periphery of the end of the steel pipe 1, the seventh driving mechanism 112 is controlled to drive the support plate 111 to flip to its avoidance position so as not to affect the movement of the roller assembly 9.
