Technical Field

[0001] This utility model relates to the field of pipe cutting equipment technology, specifically to an automatic pipe cutting and labeling device. Background Technology

[0002] Flexible hoses such as PU polyether tubing, PVC tubing, PE polyethylene tubing, silicone tubing, and Teflon tubing are commonly used in automated equipment. During equipment assembly, different hoses and their lengths often need to be marked for identification to complete the corresponding component connection and assembly operations. Currently, in actual use, the above-mentioned hoses are mostly cut to length manually and labeled manually, which is relatively inefficient and occupies a lot of manpower and space. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic tube cutting and labeling device to solve the aforementioned problems in the current tube cutting and labeling process.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An automatic pipe cutting and labeling device includes a frame and a pipe feeding mechanism, a labeling mechanism, a label rolling mechanism, a pipe cutting mechanism, and a receiving mechanism mounted on the frame. The pipe feeding mechanism is located at the rear of the frame and is used to feed pipes to be cut and labeled. The labeling mechanism is used to print and paste labels onto the pipes output by the pipe feeding mechanism. The label rolling mechanism is located between the feeding mechanism and the pipe cutting mechanism and is used to roll the labels pasted on the pipes into rings. The pipe cutting mechanism is used to cut the labeled pipes. The receiving mechanism is located below the pipe cutting mechanism and is used to receive the pipes cut by the pipe cutting mechanism.

[0005] Furthermore, the feeding mechanism includes a pipe material storage assembly and a pipe material conveying assembly, which are spaced apart. The pipe material storage assembly includes a pipe material tray, a cantilever support plate, and a rubber brake. The pipe material tray is disposed on the cantilever support plate, and the rubber brake is pressed onto the pipe material tray. The pipe material tray has rolled pipes. The pipe material conveying assembly includes a mounting base, a limiting assembly, and a synchronous belt conveying assembly. The limiting assembly is disposed at the rear of the mounting base, and the synchronous belt conveying assembly is disposed at the front of the mounting base. The limiting assembly allows pipes to pass through, and the synchronous belt conveying assembly is used to convey pipes that pass through the limiting assembly.

[0006] Furthermore, the limiting assembly includes horizontal rollers and vertical rollers. Two horizontal rollers are spaced apart in the vertical direction, and two vertical rollers are spaced apart in the horizontal direction. The two horizontal rollers and two vertical rollers are used for the pipe to pass through.

[0007] Furthermore, the synchronous belt conveying assembly is provided in two sets at intervals. Each synchronous belt conveying assembly includes a first drive motor, a drive wheel, a driven wheel, and a synchronous belt. The first drive motor is connected to the drive wheel, and the synchronous belt is disposed between the drive wheel and the driven wheel. The pipe can be conveyed by the rotation of the two sets of synchronous belts.

[0008] Furthermore, the labeling mechanism includes a support plate, a gear, a spreading cylinder, a lifting cylinder, a label roller assembly, and a drive motor. The gear is located on the upper part of the support plate, the label roller assembly is located on the gear, the spreading cylinder is located on the lower part of the support plate, and two sets of label roller assemblies are spaced apart. The support plate has an inlet hole between the two sets of label roller assemblies. The spreading cylinder is used to lift and spread the two sets of label roller assemblies. The drive motor is connected to the gear. The lifting cylinder is used to lift the pipe passing through the inlet hole. The label roller assembly is configured such that when the labeling mechanism affixes a label to the pipe, the gear drives the label roller assembly to rotate, thereby winding the label around the pipe to form a ring label.

[0009] Furthermore, the labeling mechanism includes a label printer and a labeling assembly. The label printer is mounted on the frame. The labeling assembly includes a first X-axis linear module, a first Z-axis linear module, a labeling cylinder, and a suction nozzle. The first Z-axis linear module is mounted on the first X-axis linear module. The labeling cylinder is connected to the first Z-axis linear module, and the suction nozzle is connected to the labeling cylinder. The first X-axis linear module drives the labeling cylinder to move along the X-axis direction, the first Z-axis linear module drives the labeling cylinder to move along the Z-axis direction, and the labeling cylinder drives the suction nozzle to move up and down.

[0010] Furthermore, the pipe cutting mechanism includes a blade holder, a pipe cutting fixture, a cutter, and a cutter cylinder. The pipe cutting fixture is disposed on the upper end of the blade holder, the cutter is disposed above the pipe cutting fixture, and the cutter cylinder is connected to the cutter. The cutter cylinder is used to drive the cutter to move up and down to cut the pipe located in the pipe cutting fixture.

[0011] Furthermore, the receiving mechanism includes a feeding bin, a receiving bucket, a receiving bucket collecting plate, and a receiving bucket transfer assembly. The feeding bin is located on one side of the pipe cutting mechanism and is used to receive pipes cut by the pipe cutting mechanism. The receiving bucket is located below the feeding bin and is used to receive pipes fed into the feeding bin. The receiving bucket collecting plate is located at the lower part of the frame, and multiple receiving buckets are arranged side by side on the receiving bucket collecting plate. The receiving bucket transfer assembly is used to transfer the receiving buckets that have completed receiving to the receiving bucket collecting plate, or to transfer the receiving buckets on the receiving bucket collecting plate to the area below the feeding bin.

[0012] Furthermore, the receiving bin transfer assembly includes a second X-axis linear module, a Y-axis linear module, and a receiving bin clamping component. The Y-axis linear module is connected to the second X-axis linear module, and the receiving bin clamping component is connected to the Y-axis linear module. The second X-axis linear module and the Y-axis linear module are used to cooperate to drive the receiving bin clamping component to move in order to transfer the receiving bin.

[0013] Furthermore, the receiving bucket clamping component includes a clamping cylinder and a clamping jaw, and a clamping block is provided on the side wall of the receiving bucket. The clamping jaw cylinder and the clamping jaw are used to clamp the clamping block.

[0014] The beneficial effects of this utility model are: This utility model's automatic pipe cutting and labeling equipment integrates multiple functional modules, including a pipe feeding mechanism, a labeling mechanism, a label rolling mechanism, a pipe cutting mechanism, and a receiving mechanism. These modules work collaboratively to achieve fully automated operation from pipe feeding, labeling, rolling, cutting to receiving. Compared to traditional manual operation or processing methods that rely on manual labor in certain stages, this significantly reduces human intervention, substantially improves production efficiency, and can meet the needs of large-scale industrial production.

[0015] Furthermore, the labeling mechanism adopts a combination design of a first X-axis linear module, a first Z-axis linear module, and a labeling cylinder, which, together with the suction nozzle, picks up and pastes the label. This allows for precise control of the label's position and adhesion force during the labeling process, ensuring that the label is accurately attached to the designated position on the pipe fitting, thus avoiding the deviations and instability that may occur with manual labeling.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Figures 1-10 As shown, the frame 1 of this equipment is constructed using aluminum alloy profiles. The pipe feeding mechanism 2 is located at the rear of the frame 1. The labeling mechanism 3, the label rolling mechanism 4, and the pipe cutting mechanism 5 are arranged sequentially along the pipe conveying direction. The receiving mechanism 6 is located directly below the pipe cutting mechanism 5. All mechanisms work together through a PLC control system to achieve an automated pipe cutting and labeling process.

[0020] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the tube storage assembly 21 includes a tube tray 211, a cantilever support plate 212, and a rubber brake component 213. The tube tray 211 is fitted onto the rotating shaft of the cantilever support plate 212 through a central hole. The rubber brake component 213 adopts a spring-loaded plate structure, and its working end presses against the outer edge of the tube tray 211 to form a braking friction force. When the coiled tube 7 is fitted onto the tube tray 211, the unfolding resistance of the tube 7 is controlled by adjusting the clamping force of the rubber brake component 213.

[0021] Figure 7 As shown, the pipe conveying assembly 22 includes a limiting assembly 221 and a synchronous belt conveying assembly 222. Both the limiting assembly 221 and the synchronous belt conveying assembly 222 are mounted on the mounting base 223. The limiting assembly 221 consists of two horizontal rollers 2211 (upper and lower) and two vertical rollers 2212 (left and right) forming a rectangular channel to ensure that the pipe maintains a stable posture during conveying and does not deviate. The synchronous belt conveying assembly 222 includes two sets of identical structures: a first drive motor 2221 is connected to the drive wheel 2222 via a coupling, and a synchronous belt 2224 is wound between the drive wheel 2222 and the driven wheel 2223. The synchronous belt surfaces of the two sets of synchronous belts 2224 form a clamping conveying surface. The conveying speed of the pipe 7 is controlled by adjusting the motor speed.

[0022] Figure 3 and Figure 4 As shown, the label printer 31 is a thermal transfer printer, fixed to the top of the frame 1. In the labeling assembly 32, the first X-axis linear module 321 uses ball screw drive, and the first Z-axis linear module 322 uses synchronous belt drive. The piston rod of the labeling cylinder 323 is connected to the suction nozzle 324, and the working process is as follows: 1) The first X-axis linear module 321 drives the suction nozzle 324 to move to the label outlet of the label printer 31; 2) The labeling cylinder 323 moves downwards, and the suction nozzle 324 picks up the label; 3) The first Z-axis linear module 322 and the first X-axis linear module 321 work together to attach the label to the designated position of the pipe fitting 7.

[0023] Figure 8As shown, the support plate 41 is vertically mounted on the frame 1, and the gear 42 is fixed to the upper part of the support plate 41 through a bearing seat. Two sets of label roller assemblies 43 are symmetrically arranged on both sides of the gear 42. Each set of label roller assemblies 43 includes two parallel rollers, and the lower end of the label roller assembly is provided with a roller for the cylinder 44 to open. The working process is as follows: 1) The piston rod of cylinder 44 is opened and lifted to increase the distance between the two sets of label roller assemblies 43; 2) The lifting cylinder 45 pushes the pipe fitting 7 from the inlet hole between the two sets of label roller assemblies 43 to support the pipe fitting, thereby facilitating labeling; 3) The drive motor drives the label roller assembly 43 to rotate through the gear 42, thus winding the label into a ring label.

[0024] Figure 9 As shown, the pipe cutting mechanism 5 includes a blade holder 51, a pipe cutting fixture 52, a cutter 53, and a cutter cylinder 54. The blade holder 51 adopts a C-shaped steel structure. The pipe cutting fixture 52 is fixed to the upper end face of the blade holder 51 by bolts, and its V-groove matches the outer diameter of the pipe fitting 7. The cutter cylinder 54 is vertically mounted on the top of the blade holder 51, and the cutter 53 is connected to the piston rod of the cutter cylinder 54 through a blade holder. Cutting action flow: 1) Pipe fitting 7 is conveyed to the V-groove of pipe cutting fixture 52; 2) Cylinder 54 drives the cutter downward; 3) The cutting edge of the cutter 53 works in conjunction with the pipe cutting fixture 52 to complete the cutting action.

[0025] Figure 2 and Figure 10 As shown, the receiving mechanism 6 includes a feeding bin 61, a receiving bin 62, a receiving bin collecting plate 63, and a receiving bin transfer assembly 64.

[0026] The unloading hopper 61 adopts a funnel-shaped structure, with its upper diameter greater than the length of the pipe 7 and its lower opening facing the receiving hopper 62. The receiving hopper collection plate 63 is located at the bottom of the frame 1, and its upper surface is provided with a T-slot for positioning the receiving hopper 62. In the receiving hopper transfer assembly 64, the Y-axis linear module 642 is connected to the second X-axis linear module 641 via a slider; the receiving hopper gripper 643 includes a gripping cylinder 6431 and a driving gripper 6432. The lifting and lowering of the gripping cylinder 6431 adjusts the distance between the gripper 6432 and the gripper 6432. The inner wall of the gripper 6432 is provided with anti-slip texture, which forms a friction lock with the gripping block 621 on the side wall of the receiving hopper 62. The transfer process is as follows: the gripper 6432 grips the full receiving hopper 62; the second X-axis linear module 641 and the Y-axis linear module 642 work together to move it to the receiving hopper collection plate 63; after the gripper 6432 releases the receiving hopper 62, the transfer assembly returns to grip the empty hopper.

[0027] Working principle: This equipment achieves automated operation through the following steps: Feeding stage: The tube tray 211 unfolds the tube 7 at a uniform speed under the braking of the rubber brake component 213. After being straightened by the limiting component 221, it is conveyed to the labeling station by the synchronous belt conveyor component 222. Labeling stage: The lifting cylinder 45 supports the pipe 7, and the labeling component 32 picks up the label output by the label printer 31 and attaches the label to the surface of the pipe 7 through three-dimensional motion; Labeling stage: The drive motor rotates the label roller assembly 43 to roll the label into a ring; Cutting stage: The cutter 53 of the pipe cutting mechanism 5 completes a fixed-length cut under the drive of the cylinder; Material receiving stage: After being cut, the pipe fittings 7 fall into the receiving bucket 62 through the feeding bin 61, and the transfer component 64 realizes the automatic replacement of the full bucket and the empty bucket.
