Technical Field

[0001] This utility model proposes a dual-axis pipe cutting machine, which belongs to the field of pipe cutting machines. Background Technology

[0002] Currently, paper tube cutting production requires specialized personnel to assist in machine operation. In addition, different equipment is needed to coordinate the transportation, cutting, and loading / unloading of paper tubes. Moreover, existing paper tube cutting methods have high requirements for the paper tubes used in production and cannot handle very curved paper tubes. The above situations seriously restrict the production efficiency of paper tube cutting. There is an urgent need for an automatic tube cutting machine with a compact structure and high efficiency. Utility Model Content

[0003] To address the technical problems existing in the prior art, this utility model proposes a biaxial pipe cutting machine to solve the problem of insufficient efficiency caused by inadequate compatibility between various equipment and materials. The technical features adopted are as follows:

[0004] A dual-axis pipe cutting machine includes a feeding section and a processing section fixed on a frame. The processing section includes a synchronous positioning mechanism, a cutting mechanism, an automatic loading and unloading mechanism, and a roll-changing cutting unit. The feeding section includes a rectangular storage bin, a material conveying device, a material conveying chute, a pushing chute, and a pushing device. The material conveying device has a chain plate with a bending angle of not less than 90°. The outlet of the pushing chute is aligned with the inner cutting axis of the roll-changing cutting unit in the processing section. The roll-changing cutting unit has a roll-changing disc and a power unit for driving the roll-changing disc to rotate on both sides of the left side plate of the pipe cutting machine frame. The roll-changing disc has an inner cutting axis and an outer cutting axis mounted on two fixed seats. The outer cutting axis has a synchronous positioning mechanism mounted on the right side plate of the frame. The cutting mechanism is mounted on a first linear module below the outer cutting axis. The automatic loading and unloading mechanism is mounted on a second linear module below the inner cutting axis.

[0005] Preferably, the synchronous positioning mechanism includes a sliding shaft cylinder and a piston rod passing through a fixed seat. The piston rod is connected to the sliding shaft. A top material ring is fixed on the outer ring of the sliding shaft. A U-shaped plate is provided between the sliding shaft and the top material ring. Push plates are provided at both ends of the U-shaped plate. The push plates are connected to the top material cylinder connected to the fixed seat. A limit block for adjusting the cylinder is provided on the fixed seat.

[0006] Preferably, the cutting mechanism includes a cutting device aligned with the outer cutting axis, the cutting base of the cutting device being slidably connected to the displacement base via a longitudinal lead screw, and a transverse slider being provided under the displacement base, the transverse slider being mounted on the first linear module fixed to the frame.

[0007] Preferably, the automatic loading and unloading mechanism 4 includes a second linear module on the mounting frame and loading and unloading components on the module.

[0008] Preferably, the second linear module is located below and to the side of the rewinding disc 51, and a sliding seat is mounted on the second linear module, on which a cylinder with a guide rod is mounted.

[0009] Preferably, the feeding assembly includes a gripper cylinder with a guide rod cylinder mounted on a connecting plate, and a gripper block is mounted on the gripper cylinder.

[0010] Preferably, the feeding assembly includes a side plate on a sliding seat, a slide cylinder mounted on the side plate, and a pusher block connected to the slide cylinder.

[0011] Preferably, the automatic loading and unloading mechanism 4 is connected to a finished product conveyor at its unloading port.

[0012] Preferably, the linear module includes a transmission part consisting of a slider and a groove, and a drive part consisting of a servo motor, a sprocket, and a chain groove.

[0013] The beneficial effects of this utility model are as follows:

[0014] The feeding section uses a material chain plate with a bending angle of not less than 90°, in conjunction with a rectangular storage bin and material transfer equipment, which can transport curved paper tubes, improve the fit of tube material transportation and reduce the risk of material jamming; the outlet of the pusher chute is aligned with the inner cutting shaft of the roll changing and cutting unit to ensure feeding accuracy and achieve precision processing.

[0015] The roll-changing cutting unit achieves the switching between the inner and outer cutting shafts through the roll-changing disc and the power unit, enabling material switching in a confined space.

[0028] The present invention will be further described below with reference to specific embodiments, but the present invention is not limited to the embodiments.

[0031] Furthermore, in the description of this utility model, unless otherwise stated, "multiple", "multiple groups", and "multiple roots" mean two or more.

[0032] Unless otherwise specified, the materials, instruments and methods used in the following embodiments are all conventional materials, instruments and methods in the art and can be obtained through commercial channels.

[0033] Example 1

[0034] like Figure 1 , Figure 2 As shown, the dual-axis pipe cutting machine includes a feeding section 1 and a processing section fixed on the frame. The processing section includes a synchronous positioning mechanism 2, a cutting mechanism 3, an automatic loading and unloading mechanism 4, and a roll changing and cutting unit 5. The feeding section 1 includes a rectangular storage bin, a material conveying device, a material conveying chute, a pushing chute, and a pushing device. The material conveying device has a chain plate with a bending angle of not less than 90°. In this embodiment, the chain plate adopts a bending angle design of 90° to 120°, which forms a buffer when the pipe slides from the storage bin into the chain plate, avoiding the jamming problem caused by traditional material pouring. The inclined feeding chute allows the tube to slide smoothly into the pushing chute, overcoming the problem of paper tubes being too curved to be loaded. The pushing equipment pushes the steel tube to the inner cutting shaft 53 of the coil changing and cutting unit 5 in the processing department through the pushing chute. The automatic loading and unloading mechanism 4 below the inner cutting shaft clamps and moves the tube to complete the loading. The outlet of the pushing chute is precisely aligned with the inner cutting shaft 53 of the coil changing and cutting unit 5 (deviation ≤ 0.5mm), ensuring the accuracy of the loading position. This improves efficiency by 300% compared to manual loading and reduces downtime caused by material jamming by 2-3 times per day.

[0035] The roll-changing cutting unit 5 has a roll-changing disc 51 and a power unit 52 that drives the roll-changing disc to rotate on both sides of the left side plate of the frame 7. The roll-changing disc 51 rotates 180° each time. The inner cutting shaft 53 and the outer cutting shaft 54 ​​are respectively installed on the two fixed seats on the roll-changing disc 51. The roll-changing disc 51 rotates to exchange the positions of the inner and outer cutting shafts, thereby completing the feeding of pipe and the change of the cutting station, which greatly reduces the process time. The outer cutting shaft 54 ​​is equipped with a synchronous positioning mechanism 2 on the right side plate of the frame. The synchronous positioning mechanism 2 is used to clamp the cutting shaft and the pipe to achieve good coordination between the pipe and the cutting shaft.

[0036] A cutting mechanism 3 is installed below the outer cutting shaft 54. After the pipe is cut, the cutting shaft position is changed. The cut pipe is unloaded by an automatic loading and unloading mechanism 4. A finished product conveyor 6 is connected to the unloading port at the unloading end.

[0037] Example 2

[0038] This embodiment is a further supplement to Embodiment 1, such as... Figure 3As shown, the synchronous positioning mechanism 2 includes a sliding shaft cylinder 21 and a piston rod passing through a fixed base 27. The piston rod is connected to the sliding shaft 22. A top material ring 23 is fixed on the outer ring of the sliding shaft. A U-shaped plate 24 is provided between the sliding shaft and the top material ring. Push plates 25 are provided at both ends of the U-shaped plate. The push plates 25 are connected to the top material cylinder 26 connected to the fixed base. The push plates 25 and the U-shaped plate 24 are integrally formed, which facilitates the connection between the push plates 25 and the top material cylinder 26. The installation is convenient and saves space. When the piston rod of the top material cylinder 26 is pushed out, the push plate moves under the action of the piston rod of the top material cylinder 26, pressing the end of the tube material close to the cutting end, thereby fixing the tube material. The fixed base 27 is equipped with a limiting block 28 for adjusting the cylinder. The limiting block 28 can restrict the movement of the sliding shaft and reduce the wear of the sliding shaft. When the synchronous positioning mechanism 2 is working, the sliding shaft 22 rigidly presses against the outer cutting shaft 54, effectively suppressing axial movement during the cutting process. The sliding shaft cylinder 21 pushes the top ring to press the paper tube end face in the full circumference, preventing workpiece displacement or vibration, ensuring that the cut is flat and burr-free, and responding quickly. The top cylinder 26 drives the push plate 25 to clamp from both sides. This synchronous positioning mechanism improves the positioning accuracy by 50% compared with traditional equipment, greatly improving the product cutting qualification rate.

[0039] Example 3

[0040] This embodiment is a further supplement to Embodiment 1, such as... Figure 4 As shown, the cutting mechanism 3 includes a cutting device 31 aligned with the outer cutting axis. The cutting device 31 includes a cutting base 311 and a set of cutter shaft holders 312 disposed at its front end. The cutter shaft holders 312 are movably connected to a cutter shaft 314 with at least three sets of blades 313. The multiple blades can speed up the cutting efficiency. The drive end of the cutter shaft is driven by a motor through a synchronous belt and a synchronous pulley.

[0041] When the cutting position needs to be adjusted, the cutting base 32 slides on the displacement base 34 via the longitudinal lead screw 33, achieving adjustment in the front-to-back direction; the transverse slider under the displacement base 34 moves on the first linear module 8 fixed to the frame, achieving adjustment in the left-to-right direction. The slider, slide rail transmission, servo motor, sprocket, and chain groove drive of the first linear module work together to ensure very smooth and precise movement of the cutting device, with an adjustment accuracy of up to 0.01mm. This guarantees the accuracy of the cutting position and allows for long-term operation, meeting the requirements of high-efficiency and accurate processing.

[0042] Example 4

[0043] This embodiment is a further supplement to Embodiment 1, such as... Figure 5As shown, an automatic loading and unloading mechanism 4 is located below the inner cutting shaft 53. The automatic loading and unloading mechanism 4 is mounted on the second linear module on the frame. Through the cooperation of the slider, slide rail, servo motor, sprocket, and chain groove, it drives the sliding seat to move smoothly. The second linear module 9 provides reliable power for the movement of the sliding seat 44. The overall equipment has a compact structure, and all components work in harmony, enabling it to adapt to long-term continuous operation. A guide rod cylinder 45 is provided on the sliding seat 44. The extension and retraction of the guide rod cylinder 45 allows the loading component 42 and the unloading component 43 to extend and engage with the tubular material. The feeding assembly 42 has the following structure: a gripper cylinder 421 is installed on the guide end of the guide cylinder 45 via a connecting plate. The gripper cylinder is equipped with a clamping block 422, which is used to clamp the pipe material pushed from the feeding equipment. In order to prevent the pipe material from falling off during the clamping process, there is a contact surface of not less than 1cm at the joint between the clamping block and the pipe material, so as to firmly grasp the steel pipe and achieve a 100% success rate in gripping. This reduces material waste and the trouble of manual picking, and realizes fully automatic processing and feeding.

[0044] After the pipe material is cut, the unloading assembly starts working. The structure of the unloading assembly is as follows: a side plate 46 is installed on one side of the sliding seat 44, and a sliding cylinder 431 is installed on the side plate. A pusher block 432 is connected to the sliding cylinder 431. The sliding cylinder extends to make the pusher block 432 engage with the inner cutting shaft 53. The sliding seat 44 drives the pusher block 432 to move, pushing the cut pipe material off the inner cutting shaft 53. In order to improve the smoothness of unloading, the arc of the pusher block 432 coinciding with the outer arc of the cutting shaft is greater than 1 / 8 of the arc length of the cutting shaft. For example, for a cutting shaft with a diameter of 10cm, the arc of the pusher block coinciding with the cutting shaft is between 3.5cm and 15cm, and there will be no jamming. The appropriate selection should be made according to the material cost.

[0045] The cut pipe material is pushed out from the inner cutting shaft 53 by the feeding assembly and falls into the finished product conveyor 6 below the inner cutting shaft. It is then transported to the designated finished product stacking area, realizing automation from cutting to finished product stacking, reducing the number of manual operations by 2 and lowering labor costs.

[0046] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Anyone skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
