Description

Technical Field

[0001] This utility model belongs to the field of pipe cutting technology, and relates to laser pipe cutting machines, and in particular to the protective structure for material conveying in laser pipe cutting machines. Background Technology

[0002] Laser tube cutting machines are mainly used to cut various hollow round tubes of non-metallic solid materials, such as plastic tubes, PVC tubes, PVB tubes, and other industrial and civil materials. These laser machines use CO2 metal laser tubes and consume approximately 100W-500W of power, making them the preferred processing machinery for small and medium-sized enterprises.

[0003] For example, the laser tube cutting machine disclosed in CN206883018U includes a frame, on which a control system, a cutting mechanism, a pushing mechanism, and at least two top-loading mechanisms are provided. The top-loading mechanisms are vertically and vertically connected to the frame. The top-loading mechanism includes a first position for placing materials and a second position for the pushing mechanism to pass through after lowering. The pushing mechanism slides along the X-axis of the frame. The cutting mechanism includes a laser cutting head, which slides along the Y-axis and Z-axis of the frame. The control system is connected to the cutting mechanism, the pushing mechanism, and the top-loading mechanism respectively, and is used to drive the cutting mechanism, the pushing mechanism, and the top-loading mechanism.

[0004] During transportation and handling, some pipes may bend due to impacts. However, existing laser pipe cutting machines cannot correct the bends, resulting in defective pipes after cutting. Utility Model Content

[0005] This utility model provides a protective structure for material conveying in a laser tube cutting machine, which can straighten the tube before cutting.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a protective structure for material conveying in a laser tube cutting machine, including a conveying frame, a storage section and a conveying section on the conveying frame, a first extrusion plate slidably connected to the conveying section, and a plurality of second extrusion plates rotatably connected to the conveying section, with a limiting block fixedly connected to the side of the second extrusion plate away from the first extrusion plate. When the tube is located on the storage section, the second extrusion plate and the conveying section are perpendicular to each other. When the tube rolls from the storage section into the conveying section, the second extrusion plate rotates towards the side of the first extrusion plate. When the tube is located in the conveying section, the first extrusion plate slides so that the tube abuts against the second extrusion plate and the second extrusion plate abuts against the limiting block.

[0007] A further preferred embodiment of this utility model is as follows: a plurality of cylinders are fixedly connected to the conveyor frame, and the extrusion plate is fixedly connected to the output end of the cylinders.

[0008] A further preferred embodiment of this utility model is as follows: the second extrusion plate is connected to the conveying part by a pin, and a torsion spring for driving the second extrusion plate to reset is provided between the pin and the second extrusion plate.

[0009] A further preferred embodiment of this utility model is that there is a gap between the extrusion plate and the conveying part, and the size of the gap is smaller than the diameter or height of the pipe.

[0010] A further preferred embodiment of this utility model is that the limiting block is provided with an arc-shaped surface.

[0011] A further preferred embodiment of this utility model is that at least two limiting blocks are provided.

[0012] A further preferred embodiment of this utility model is as follows: a groove is provided on the conveying part, and a plurality of rollers are rotatably connected in the groove. When the pipe is located in the conveying part, the rollers rotate.

[0013] A further preferred embodiment of this utility model is that a plurality of motors for driving the drum to rotate are fixedly connected to the conveyor frame.

[0014] A further preferred technical solution of this utility model is: a sensing element is provided on the bottom surface of the conveying section, and when the pipe contacts the sensing element, the motor and cylinder are started.

[0015] A further preferred embodiment of this utility model is that the conveyor frame is equipped with an indicator light connected to the sensing element.

[0016] Compared with the prior art, this utility model includes a conveyor frame, which is provided with a storage section and a conveying section. An extrusion plate 1 is slidably connected to the conveying section, and an extrusion plate 2 is rotatably connected to the conveying section. A limit block is fixedly connected to the conveying section. When the tube is located on the storage section, the extrusion plate 2 is perpendicular to the conveying section. When the tube rolls from the storage section into the conveying section, the extrusion plate 2 rotates towards the side of the extrusion plate 1. When the tube is located in the conveying section, the extrusion plate 1 slides so that the tube abuts against the extrusion plate 2 and the extrusion plate 2 abuts against the limit block. Therefore, before laser cutting the tube, the tube rolls from the storage section into the conveying section. At this time, the sliding extrusion plate 1 makes the tube abut against the extrusion plate 2 and corrects the tube in the process. Attached Figure Description

[0024] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0025] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0026] Figure 1 and Figure 2 As shown, the protective structure for material conveying in the laser tube cutting machine includes a conveyor frame 1, a storage section 2 and a conveying section 3 on the conveyor frame 1, a pressing plate 4 slidably connected to the conveying section 3, and several cylinders 5 fixedly connected to the conveyor frame 1. The pressing plate 4 is fixedly connected to the output end of the cylinders 5, and the cylinders 5 play the role of pushing the pressing plate 4 to slide.

[0027] Figure 1 and Figure 2 As shown, there is a gap between the extrusion plate 4 and the conveying part 3. The gap is smaller than the diameter or height of the pipe. This design can prevent the extrusion plate 4 from rubbing against the bottom surface of the conveying part 3, thus affecting the sliding. This design effectively reduces the friction generated when the extrusion plate 4 slides.

[0028] Figures 1-4 As shown, several extrusion plates 9 are rotatably connected to the conveying section 3 and are used in conjunction with the extrusion plate 4. When the pipe is located on the storage section 2, the extrusion plates 9 are perpendicular to the conveying section 3. When the pipe rolls from the storage section 2 into the conveying section 3, the extrusion plates 9 rotate towards the side of the extrusion plate 4. The extrusion plates 9 are connected to the conveying section 3 by a pin 12. A torsion spring 13 is provided between the pin 12 and the extrusion plates 9 to drive the extrusion plates 9 to reset.

[0029] Figure 1 and Figure 2 As shown, during the straightening of the pipe, the pipe rolls from the storage section 2 into the conveying section 3. At this time, the second extrusion plate 9 rotates towards the first extrusion plate 4 due to the push of the pipe, so that the pipe can smoothly enter the conveying section 3. Then, the cylinder 5 is activated to make the first extrusion plate 4 slide and cooperate with the second extrusion plate 9 to clamp the pipe between the first extrusion plate 4 and the second extrusion plate 9. At this time, the bent pipe is straightened due to the extrusion. This design plays a role in straightening the pipe and reducing defective products.

[0030] Figures 1-4 As shown, the conveying section 3 is fixedly connected to the limiting block 11 on the side of the extrusion plate 2 9 away from the extrusion plate 1 4. When the pipe is inside the conveying section 3, the extrusion plate 1 4 slides so that the pipe abuts against the extrusion plate 2 9 and the extrusion plate 2 9 abuts against the limiting block 11.

[0031] Figures 1-4 As shown, when the extrusion plate 4 and the extrusion plate 9 work together to straighten the pipe, the limiting block 11 can limit the rotation range of the extrusion plate 9 and prevent the extrusion plate 9 from rotating to the side away from the extrusion plate 4 during the straightening process. This design can ensure the smooth progress of the straightening.

[0032] Figures 1-4 As shown, the limiting block 11 is provided with an arc-shaped surface 14, which allows the pipe to roll smoothly into the conveying section 3 along the arc-shaped surface 14, preventing the limiting block 11 from blocking the pipe.

[0033] Figures 1-4 As shown, at least two limiting blocks 11 are provided, so that when the extrusion plate 14 and the extrusion plate 29 are used to straighten the pipe, the force exerted by the limiting block 11 on the extrusion plate 29 can be uniform, thus preventing the extrusion plate 29 from bending.

[0034] Figures 1-4As shown, the conveying section 3 has a groove 8, and several rollers 6 are rotatably connected in the groove 8. When the pipe is located in the conveying section 3, the rollers 6 rotate. Several motors 7 for driving the rollers 6 to rotate are fixedly connected on the conveying frame 1.

[0035] Figures 1-4 As shown, when the pipe enters the conveying section 3, the rotation of the roller 6 causes the pipe to rotate as well, which facilitates the extrusion plate 4 and the extrusion plate 9 to more comprehensively correct the pipe and effectively improve the correction effect.

[0036] Figures 1-5 As shown, a sensor 15 is provided on the bottom surface of the conveying section 3. When the pipe contacts the sensor 15, the motor 7 and the cylinder 5 are started. An indicator light 10 connected to the sensor 15 is provided on the conveying frame 1. This design allows the sensor 15 to sense the pipe and turn on the motor 7 and the cylinder 5 when the pipe falls into the conveying section 3. At this time, the indicator light 10 lights up, indicating that the pipe is being corrected. This design facilitates the control of the cylinder 5 and the motor 7, and the indicator light 10 makes it easy for the staff to observe.

[0037] The protective structure for material conveying in the laser tube cutting machine provided by this utility model has been described above. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand this utility model and its core ideas. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
