[0042] The following will introduce the embodiments of the present invention in detail with reference to the accompanying drawings.

[0043] Refer to Figures 1 - 19 , the present invention provides a high-precision inkjet coding and pipe cutting system, including a loading device 1, a traction device 2 and a cutting device arranged in sequence.

The loading device 1 includes a material tray with a brake, and the inclination angle of the material tray is adjustable, and the discharging direction of the pipe material can be adjusted.

[0045] Refer to Figures 1 - 7 , the loading device 1 includes a base 11, a rotating bracket 13, a material tray, a variable-diameter tensioning mechanism 16 and a braking mechanism 17.

[0046] Among them, the base 11 serves as an installation carrier. The rotary bracket 13 is rotatably installed on the base 11, and the rotation axis of the rotary bracket 13 is parallel to the horizontal plane, so that the inclination angle of the material tray can be adjusted to adapt to the feeding of pipe material coils with different inclination directions. The driving device is installed on the base, connected to the rotary bracket 13, and used to drive the rotary bracket to rotate, thereby realizing the adjustment of the inclination. The material tray is rotatably installed on the rotary bracket 13, and its rotation axis is perpendicular to the rotation axis of the rotary bracket 13. In this embodiment, the rotation axis of the rotary bracket 13 is perpendicular to and intersects the rotation axis of the rotary bracket 13, and the material tray is used to place the pipe material coil.

[0047] The variable-diameter tensioning mechanism 16 can achieve variable diameter, and thus can adapt to pipe material coils with different diameters, tension and fix them to ensure the stability and accuracy of the feeding process and improve production efficiency. The variable-diameter tensioning mechanism 16 includes material rods 163. The axis of the material rod 163 is parallel to the axis of the material tray. There are multiple material rods 163 and they are circumferentially distributed along the axis of the material tray. Preferably, there are three material rods. Each material rod 163 can achieve synchronous radial movement, and its movement direction is perpendicular to the axis of the material tray. By moving each material rod inward or outward synchronously, the radial tension or relaxation of the pipe material coil is realized, and it can adapt to pipe material coils with different apertures, ensuring the stability and precision of the pipe material during the cutting process and improving the overall working efficiency.

[0048] The braking mechanism 17 is installed on the rotary bracket 13 and is used to lock and fix the material tray to control the discharge length or tightness of the pipe material to ensure the cutting quality.

[0049] Specifically, a first support 111 and a second support 112 are provided on the base 11. The first support 111 and the second support 112 are arranged at both ends of the base 11. The rotary bracket 13 is rotatably installed between the first support 111 and the second support 112, and its rotation axis is parallel to the horizontal connection line of the first support 111 and the second support 112. Among them, a driving device is provided in the first support 111 for driving the rotary bracket 13 to rotate. The driving device is a driving motor 1101 and a speed reducer arranged at the output end of the driving motor 1101. In this embodiment, the driving motor 1101 is a servo motor, and the speed reducer is an RV reducer, which can achieve precise control of the tilt angle of the rotary bracket 13; a limiting device is provided on the rotary bracket 13 for limiting the rotation angle of the rotary bracket 13 to prevent it from rotating overstroke. In this embodiment, a turntable 12 is installed at the output end of the speed reducer. The turntable 12 is connected to one end of the rotary bracket 13. A limiting groove is opened on the turntable 12. The limiting groove is an arc-shaped groove, which is coaxial with the axis of the turntable 12, and its central angle is 60 degrees - 120 degrees. At the same time, a limiting rod is provided on the first support 111, which is sleeved in the limiting groove for realizing the rotational limit of the turntable 12, which is a physical limit; at the same time, a limit switch is provided on the turntable. The limit switch is an inductive switch or a contact switch. Correspondingly, a triggering part is provided on the first support 111 for triggering the inductive switch or the contact switch. It is located at the two extreme positions of the turntable to realize electrical limit, which can improve the safety and stability of automatic adjustment.

[0050] The material tray includes a blanking tray 14 and a loading tray 151 arranged coaxially. The blanking tray 14 is rotatably installed on the rotary bracket 13. The blanking tray 14 is a non-powered tray or a powered tray, that is, it can rotate by relying on the pulling force of the pipe material, or it can be driven by a motor; the loading tray 151 is rotatably installed at the upper end of the blanking tray 14 and is coaxial with the blanking tray 14. The loading tray 151 is also a non-powered tray, which is mainly used for the placement of the pipe material coil and the setting of the variable diameter tensioning mechanism 16. Specifically, the variable diameter tensioning mechanism 16 is installed on the blanking tray 14. At the same time, a strip-shaped groove 1510 is opened on the loading tray 151. The strip-shaped groove 1510 is used for the material rod 163 of the variable diameter tensioning mechanism 16 to pass through and allow its radial movement, thereby realizing variable diameter and achieving the functions of tensioning or relaxing, ensuring the stability of the pipe material during the cutting process.

[0051] In order to improve the overall structural compactness and aesthetics, a cylindrical material cylinder 152 is provided on the edge of the blanking tray 14. The material cylinder 152 is coaxial with the blanking tray 14. The loading tray 151 is located inside the material cylinder 152. A material placement area is formed between the upper surface of the loading tray 151 and the inner wall of the material cylinder 152 for placing the pipe material coil; a notch is opened on the side wall of the material cylinder to form a discharge port, which faces the guiding mechanism for discharging the pipe material.

[0052] Specifically, the variable-diameter tensioning mechanism 16 further includes a guide rail 161 fixed to the blanking disk 14. In this embodiment, the axis of the guide rail 161 is perpendicular to and intersects the axis of the blanking disk 14. There are at least three guide rails 161 and they are circumferentially evenly distributed, preferably three. A slider 162 is slidably arranged on the guide rail 161. The sliding direction of the slider 162 is perpendicular to and intersects the axis of the blanking disk 14. A material rod 163 is vertically fixed to the slider 162, and the axis of the material rod is parallel to the axis of the blanking disk 14. A tensioning area is formed between the material rods 163 for contacting the central hole of the pipe material coil to achieve tensioning or relaxation. At the same time, a pushing cylinder 164 is provided between the blanking disk 14 and the loading disk 151. The pushing cylinder 164 can cause relative rotation between the loading disk 151 and the blanking disk 14. Its length direction has a certain angle with the radial direction of the blanking disk or the loading disk 151. One end of it is hinged to the blanking disk 14 and the other end is hinged to the loading disk 151. During adjustment, relative rotation between the loading disk 151 and the blanking disk 14 is achieved through the telescoping of the cylinder. At the same time, the strip-shaped groove 1510 is an inclined guide groove, and its length direction is inclined to the radial direction of the loading disk 151. In this application, the strip-shaped groove 1510 is an arc-shaped groove, which can allow the material rod 163 to pass through and provide a movement space for its radial inward and outward movement. At the same time, the strip-shaped groove has a certain angle with the radial direction of the loading disk 151. When the loading disk 151 rotates relative to the blanking disk 14, the strip-shaped groove 1510 has a guiding effect on the material rod 163. The side wall of the strip-shaped groove 1510 contacts the side wall of the material rod 163. When the loading disk 151 rotates, the strip-shaped groove can drive each material rod 163 to move inward or outward synchronously to achieve variable diameter.

[0053] The braking mechanism 17 is installed on the rotating bracket 13 and is used to lock and fix the material disk. Specifically, the braking mechanism 17 includes a clamping cylinder 171. In this application, the clamping cylinder 171 has two output ends, and the two output ends can move closer to or away from each other. The direction of its approaching or moving away is parallel to the rotation axis of the material disk. Braking blocks 172 are arranged on both output ends. Through the action of the clamping cylinder 171, the braking blocks 172 can move closer to or away from each other. A braking area is formed between the two braking blocks 172. The edge of the material disk is located in the braking area, or a brake pad is provided on the material disk and the brake pad is located in the braking area. The edge of the material disk or the brake pad is clamped by the braking blocks 172 to achieve braking. In this embodiment, the edge of the blanking disk 14 is located in the braking area. During braking, the two braking blocks 172 clamp the edge part of the blanking disk 14 to achieve braking (braking) of the material disk.

[0054] To improve the supporting force of the loading tray 151 and prevent it from deforming, a first support seat 141 is provided at the upper end of the unloading tray 14. The first support seats 141 are multiple and evenly distributed circumferentially. They are arranged at the end far from the rotation axis and are used to support the loading tray 151. At the top of the first support seat 141, there are balls or bearings (rollers). The balls or bearings can contact the bottom surface of the loading tray 151. While achieving support, the friction between the loading tray 151 and the first support seat 141 during rotation is reduced, the rotation smoothness of the loading tray 151 is improved, and the load on the pushing cylinder 164 is reduced.

[0055] To improve the supporting force of the unloading tray 14 and prevent it from deforming, a second support seat 18 is provided on the rotating bracket. The second support seats 18 are also multiple and evenly distributed circumferentially. They are arranged at the end far from the rotation axis. On the second support seat 18, there are balls or bearings (rollers). The balls or bearings contact the lower bottom surface of the unloading tray 14, achieving the support of the unloading tray 14, improving its stability during rotation, and preventing it from deforming.

[0056] The material guiding mechanism 19 is arranged on the second support 112. A material guiding channel is provided on the material guiding mechanism 19. It can allow the pipe material to pass through and is used to guide the pipe material to smoothly enter the cutting area, ensuring the smoothness and accuracy of the pipe material during the cutting process. The axis of the material guiding channel is parallel to the rotation axis of the rotating bracket 13. In this embodiment, the axis of the material guiding channel and the axis of the rotating bracket 13 are in the same vertical plane.

[0057] Specifically, the material guiding mechanism 19 includes a first lower guide roller 191 and a first upper guide roller 192. There are two first upper guide rollers 192 and two first lower guide rollers 191, and they are arranged in parallel. In this embodiment, they are both horizontally arranged. Among them, the first upper guide roller 192 is located directly above the first lower guide roller 191 and can move up and down through the first lifting cylinder 194. A material passing area is formed between the first lower guide roller 191 and the first upper guide roller 192 for the pipe material to be cut to pass through. At the same time, on both sides of the inlet end and the outlet end of the material passing area, there are first vertical guide rollers 193. The axis of the first vertical guide roller 193 is perpendicular to the axis of the first upper guide roller 192 or the first lower guide roller 191. In this embodiment, they are all perpendicular to the horizontal plane. The above-mentioned first lower guide roller 191, first upper guide roller 192, and first vertical guide roller 193 form a material guiding channel for guiding the pipe material to discharge. During guiding, the first vertical guide rollers on both sides of the inlet end and the outlet end of the material passing area are used to limit the left and right positions and guide the pipe material during the conveying process. The first upper guide roller 192 can move up and down, thereby controlling the height of the material passing area, realizing the adjustment of the clamping force on the pipe material, and further realizing different frictions on the pipe material during the conveying process to achieve the smooth conveying of the pipe material.

[0058] The material tray of the feeding device adopts a rotating structure, which can adjust the tilt angle of the material tray, thereby adjusting the discharging angle of the pipe material, ultimately improving the cutting accuracy of the pipe material, especially the cutting accuracy of the incision, and preventing the incision from tilting; a braking mechanism is provided to lock and fix the material tray to control the discharging length or tightness of the pipe material, thereby ensuring the cutting quality; a variable-diameter tensioning mechanism is provided to achieve variable diameter, and thus can adapt to pipe material coils of different diameters, tension and fix them, ensuring the stability and accuracy of the feeding process and improving production efficiency.

[0059] Refer to Figure 1 、 Figures 10 - 19 , the traction device 2 is arranged at the discharging end of the feeding device 1 for pipe material traction. Refer to Figures 8 - 9 , the traction device 2 includes a traction mechanism 22 and a detection mechanism. Among them, the traction mechanism 22 includes a second lower guide roller 221 and a second upper guide roller 222 that are parallel to each other. Among them, the second lower guide roller 221 is connected to a motor and can rotate independently to provide power for traction. The diameter of the second lower guide roller 221 is larger than that of the second upper guide roller 222. At the same time, multiple second upper guide rollers 222 are parallel to each other and are located on the same horizontal plane. The second upper guide roller 222 is located directly above the second lower guide roller 221 and can move up and down through a second lifting cylinder. A traction area is formed between the second lower guide roller 221 and the second upper guide roller 222 for the pipe material to pass through and achieve traction. At the same time, second vertical guide rollers 223 are provided on both sides of the inlet end and the outlet end of the traction area. The axis of the second vertical guide roller 223 is perpendicular to the axis of the second upper guide roller 222 or the second lower guide roller 221. A traction channel is formed among the second lower guide roller 221, the second upper guide roller 222, and the second vertical guide roller 223 for pulling the pipe material out of the material. During guiding, the second upper guide roller 222 descends to a certain height and contacts the pipe material in the traction area, pressing it against the second lower guide roller 221. The second lower guide roller 221 rotates and drives the pipe material to move under the action of friction to achieve traction.

[0060] Horizontal guide rollers 224 are provided at both ends of the traction mechanism to support the pipe material, reduce friction, and improve the smoothness of transportation.

[0061] On the traction device 2, there is a material passing channel 230 through which the pipe material passes. The material passing channel 230 is arranged at the outlet end of the traction channel and is used to detect the tension of the pipe material. Specifically, an over-tight proximity switch 242 is provided at the upper end of the outlet end of the material passing channel 230, and a lack-of-material proximity switch 241 is provided at the lower end of the outlet end of the material passing channel 230. Both the over-tight proximity switch 242 and the lack-of-material proximity switch 241 are proximity switches. In this application, the over-tight proximity switch 242 is located on the axis of the traction area, that is, on the same horizontal plane as the traction area, and the lack-of-material proximity switch 241 is directly below the over-tight proximity switch 242. When the pipe material triggers the over-tight proximity switch 242, it means that the pipe material is over-tight. At this time, the brake of the material tray of the feeding device 1 is released, so that the material tray can rotate; when the pipe material triggers the lack-of-material proximity switch 241, it means that the pipe material lacks material or is over-loose. At this time, the brake of the material tray of the feeding device 1 is turned on to brake the material tray. Through the above functional cooperation, the pipe material is kept operating within the range of lack-of-material proximity and over-tight proximity, ensuring the cutting accuracy and efficiency.

[0062] In this application, a roller 25 is provided below the outlet end of the material passing channel 230 for contacting the over-loose pipe material; baffles 23 are provided on both sides of the material passing channel 230, and a chamber with an open upper end is formed between the two baffles 23, which is convenient for the pipe material to pass through, prevents external interference, and can improve the overall aesthetics.

[0063] The cutting device 3 is arranged at the discharge end of the traction device 2. Along the conveying direction of the pipe material on the cutting device 3, a first guiding device 41, a feeding device 5, a second guiding device 42, a coding device 6 and a pipe cutting device are arranged in sequence;

[0064] The first guiding device 41 and the second guiding device 42 are used to guide the pipe material. They are located on the same straight line to ensure the straightness of the pipe material during the conveying process. A measuring roller that can contact the pipe material and rotate as the pipe material moves is provided on the second guiding device 42, and an encoder 422 is provided on the measuring roller, so as to detect the length of the passing pipe material and achieve precise cutting.

[0065] Refer to Figure 14The first guide device 41 includes a third lower guide roller 411 and a third upper guide roller 412.
