Description

Technical Field

[0001] This utility model relates to the technical field of automated plastic tube processing equipment, and in particular to a rapid grooving and marking device for plastic tubes. Background Technology

[0002] Plastic tubing is widely used in industries such as textiles and packaging. Traditional tubing, due to its symmetrical structure at both ends, requires manual differentiation of the left and right ends during use (e.g., distinguishing the inlet / outlet end). Current technology typically uses labeling or color marking, which has the following drawbacks:

[0003] The labels are easily detached or worn, leading to confusion;

[0004] Manual labeling is inefficient (time per item > 30 seconds) and has high labor costs.

[0005] Inks / labels increase material costs and environmental pressures.

[0006] Therefore, there is an urgent need to develop an efficient and low-cost physical identification solution. Utility Model Content

[0007] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a quick-grooving and marking device for plastic tubes.

[0008] A quick-grooving and marking device for a plastic tube according to a first aspect embodiment of the present invention is characterized in that it comprises:

[0009] frame;

[0010] A tube positioning mechanism is installed on the frame and includes a positioning groove and a positioning sleeve disposed at the end of the positioning groove. The positioning sleeve is semi-circular, and a limiting block for workpiece positioning is also provided at the bottom of the positioning groove.

[0011] The grooving actuator is located below the positioning groove and includes a linear slide, a high-speed electric spindle mounted on the linear slide, and a tapered milling cutter.

[0012] The control system includes a PLC controller electrically connected to the high-speed electric spindle and a foot switch electrically connected to the PLC controller.

[0013] A rapid grooving and marking device for plastic tubes according to an embodiment of this utility model has at least the following beneficial effects: The rapid grooving and marking device for plastic tubes provided by this utility model accurately constrains the end position of the tube by setting a semi-circular positioning sleeve, and achieves precise axial positioning of the tube by combining the limiting block at the bottom of the positioning groove, which significantly improves the consistency and stability of workpiece clamping and effectively avoids deviation during processing. The grooving execution mechanism (including a linear slide, a high-speed electric spindle, and a tapered milling cutter) is integrated below the positioning groove, resulting in a compact and reasonable structural layout, shortening the tool travel, and optimizing the processing path. Under the coordinated control of a PLC controller and a foot switch, this device can achieve rapid clamping, precise positioning, and efficient grooving of the tube, with a single-piece processing time controllable to within 3 seconds. Compared to traditional labeling or coloring methods, the tapered groove marking formed by milling at the end of the tube by this device has significant advantages such as permanence and resistance to wear and detachment, completely solving the problem of confusion between the left and right ends of the tube. At the same time, it has a high degree of automation and is easy to operate (processing is completed by a single foot pedal trigger), which greatly improves the marking efficiency (efficiency is increased by more than 10 times), significantly reduces labor costs, material consumption (no label ink required) and maintenance costs, and has significant overall benefits.

[0014] According to some embodiments of the present invention, a pneumatic gripper for clamping the workpiece is installed on the side of the positioning groove.

[0015] According to some embodiments of this utility model, the cone angle of the tapered milling cutter is 55°-65° and the cutting length is 3-5mm.

[0027] Reference Figure 1 , 2 A quick-grooving and marking device for plastic tubing according to a first aspect of the present invention is characterized in that it comprises:

[0028] The frame 1, which forms a rigid support foundation for the device, provides a stable mounting platform for the tube positioning mechanism 2, the grooving actuator 3, and the control system 4.

[0029] The tube positioning mechanism 2, mounted on the frame 1, includes a positioning groove 201 and a positioning sleeve 203 disposed at the end of the positioning groove 201. The positioning groove 201 is configured as a V-shaped or semi-enclosed structure to adapt to tubes of different diameters, achieving rapid rough positioning and reducing manual adjustment time. The positioning sleeve 203 is semi-circular, and the semi-circular positioning sleeve 203 radially constrains the end face of the tube, eliminating the risk of circumferential displacement of the tube during processing and ensuring that the grooving position is always located in the center area of ​​the end face. The bottom of the positioning groove 201 is also provided with a limiting block 204 for workpiece positioning. The limiting block 204 at the bottom of the positioning groove 201 precisely limits the axial position of the tube, preventing the workpiece from moving back and forth, so that the tapered milling cutter 303 can accurately groove at a preset depth, avoiding inconsistent groove depth or processing failure due to displacement.

[0030] The grooving actuator 3 is located below the positioning groove 201, optimizing the spatial layout, shortening the movement distance between the tapered end mill 303 and the workpiece, reducing idle travel time, and enhancing structural rigidity to suppress machining vibration. It includes a linear slide 301, a high-speed electric spindle 302 mounted on the linear slide 301, and a tapered end mill 303. The linear slide 301 provides high-precision linear feed (repeat positioning accuracy ±0.05mm), and its fast response characteristics (start and stop time ≤0.2s) are the core guarantee for achieving "3-second machining". The tapered end mill 303 is machined with a permanent tapered groove on the end face of the tube, which is different from easily detachable ink or labels. The tapered structure is easier to identify quickly by touch / visual sense, eliminating confusion between the left and right ends.

[0031] The control system 4 includes a PLC controller 401 electrically connected to the high-speed electric spindle 302 and a foot switch 402 electrically connected to the PLC controller 401. Controlling the start and stop of the high-speed electric spindle 302 using the PLC controller 401 and the foot switch is common knowledge and can be easily understood by those skilled in the art. Furthermore, the working principle of the PLC controller 401 and the foot switch is not within the protection scope of this application, so it will not be described in detail here.

[0032] According to an embodiment of this utility model, a rapid grooving and marking device for plastic tubes has at least the following beneficial effects: The rapid grooving and marking device for plastic tubes provided by this utility model accurately constrains the end position of the tube by setting a semi-circular positioning sleeve, and achieves precise axial positioning of the tube by combining the limiting block 204 at the bottom of the positioning groove 201, which significantly improves the consistency and stability of workpiece clamping and effectively avoids deviation during processing. The grooving execution mechanism 3 (including a linear slide 301, a high-speed electric spindle 302, and a tapered milling cutter 303) is integrated below the positioning groove 201, resulting in a compact and reasonable structural layout, shortening the tool travel, and optimizing the processing path. Under the coordinated control of the PLC controller 401 and the foot switch, this device can achieve rapid clamping, precise positioning, and efficient grooving of the tube, and the processing time for a single piece can be controlled within 3 seconds. Compared to traditional labeling or coloring methods, the tapered groove marking formed by milling at the end of the tube by this device has significant advantages such as permanence and resistance to wear and detachment, completely solving the problem of confusion between the left and right ends of the tube. At the same time, it has a high degree of automation and is easy to operate (processing is completed by a single foot pedal trigger), which greatly improves the marking efficiency (efficiency is increased by more than 10 times), significantly reduces labor costs, material consumption (no label ink required) and maintenance costs, and has significant overall benefits.

[0033] According to some embodiments of this utility model, a pneumatic gripper for clamping the workpiece is installed on the side of the positioning groove 201. The pneumatic gripper applies lateral pressure to form an active constraint force in the radial direction of the tube, forming a three-point positioning system (bottom support + side clamping) together with the V-shaped / semi-circular structure of the positioning groove 201. Compared to passive positioning relying solely on gravity, this design completely eliminates the risk of micro-displacement of the tube during high-speed milling, especially suppressing workpiece wobble caused by cutting vibration, ensuring groove accuracy (±0.1mm) and groove depth consistency (0.5–1mm). The clamping stroke of the pneumatic gripper is adjustable, and combined with the inclusive structure of the positioning groove 201, it can seamlessly adapt to various tubes with diameters of 30–80mm without the need to change fixtures. The arc-shaped pressure head (preferably made of polyurethane) at the end of the gripper provides a high coefficient of friction while avoiding damage to the plastic tube wall, meeting the flexible production needs of multiple specifications of products. In addition, the gripper action is controlled by the PLC program and is deeply linked with the processing flow. Stepping on the foot switch → the gripper clamps synchronously (response time ≤ 0.3s) → grooving is performed → automatic release after processing is completed. This timing design fully integrates the clamping action into the automatic cycle, eliminates the manual locking link, and strictly controls the processing time of a single piece within 3 seconds, which is 40% more efficient than the manual fixing method.

[0034] According to some embodiments of this utility model, the tapered end mill 303 has a taper angle of 55°-65° and a cutting length of 3-5mm.

[0035] According to some embodiments of this utility model, the inner side of the V-shaped positioning groove 201 is provided with an anti-slip rubber pad 202. The anti-slip rubber pad 202 (Shore hardness 60A-70A) has a coefficient of friction of 0.8-1.2 with the surface of the plastic tube (more than 3 times higher than that of the metal groove), forming a high-damping interface. This effectively prevents the tube from rolling due to its own weight before the pneumatic grippers apply pressure, eliminating the need for manual straightening during clamping and reducing the preparation time for a single piece by 0.5 seconds.

[0036] According to some embodiments of the present invention, the linear slide 301 is pneumatically driven or driven by a servo motor.

[0037] The embodiments described above with reference to the accompanying drawings have been described in detail. However, the embodiments are not limited to those described above. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the invention.
