Description

Technical Field

[0001] This utility model belongs to the field of pipe cutting machines, and relates to a clamping and conveying mechanism and a fully automatic pipe cutting machine. Background Technology

[0002] For tubular components such as paper tubes and plastic tubes that undergo deformation under stress, an internal support structure is required to enter the interior of the tubular component during cutting; otherwise, the cutting effect will be poor.

[0003] For example, Chinese patent literature discloses a rotary automatic feeding pipe cutting machine [202122102023.1], which includes an automatic feeding component, which is set on one side of the pipe cutting machine tool. The top of the pipe cutting machine tool has drive slides on both sides. A power output component is slidably connected to the drive slides. Multiple material lifting devices are set between the two drive slides. The material lifting devices are fixed on the top of the pipe cutting machine tool in a row. A pipe cutting machine is set at one end of the pipe cutting machine tool. The power output component includes a housing, and a base is fixedly installed on the bottom side inside the housing. A drive motor is installed on the base, and a main gear is connected to the output shaft of the drive motor. The main gear is meshed with a driven gear, and the driven gear is installed on a second rotating shaft. The end of the second rotating shaft away from the driven gear is fixedly connected to a rotary chuck, and the second rotating shaft is fixedly installed on the base.

[0004] The drawback of the above technical solution is that: when using V-grooves to push and transport tubular components, the central axis displacement of tubular components of different sizes is slightly off, which reduces the accuracy of subsequent connection of tubular components and makes them prone to breakage.

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a clamping and conveying mechanism and a fully automatic pipe cutting machine.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] The clamping and conveying mechanism includes:

[0008] frame;

[0009] An auxiliary lifting device is provided, which includes an auxiliary conveyor frame that moves vertically along the frame;

[0010] The lower adjustment device includes two lead screw nuts symmetrically rotated on both sides of the auxiliary conveyor frame, a lead screw lifting rod threaded through each lead screw nut and connected to the lead screw nut, a lower adjustment frame between the two lead screw lifting rods and at one end away from the auxiliary conveyor frame, a transmission gear sleeved on the outside of the lead screw nut, and a gear driver rotatably mounted on the auxiliary conveyor frame and synchronously driving the two transmission gears.

[0012] The clamping and conveying device includes auxiliary conveying rollers that are spaced apart at the bottom of the upper adjusting frame and the upper end of the lower adjusting frame, and receiving grooves that are disposed on the circumferential outer wall of the auxiliary conveying rollers. The receiving grooves between the vertically spaced auxiliary conveying rollers together form a clamping and positioning opening.

[0013] Furthermore, the auxiliary lifting device also includes two auxiliary lifting guide rails spaced apart on the frame, the two ends of the auxiliary conveyor frame being slidably mounted on the auxiliary lifting guide rails, and an auxiliary lifting cylinder mounted on the frame and driving the auxiliary conveyor frame.

[0014] Furthermore, the auxiliary conveyor frame is provided with a transverse guide groove arranged along the length direction, and a sliding mounting plate that slides along the transverse guide groove is provided at the upper end of the auxiliary conveyor frame.

[0015] Furthermore, one side of the sliding mounting plate is provided with a mounting extension protruding from the auxiliary conveyor frame, and both the lower adjustment device and the upper adjustment device are connected to the mounting extension.

[0016] Furthermore, the gear drive includes two gear shafts hinged to the sliding mounting plate and respectively meshing with the transmission gear, a coupling connecting the two gear shafts, and a synchronous drive for driving the gear shafts to rotate.

[0017] Furthermore, both the upper and lower adjustment frames are provided with insertion notches, and a hinge frame extends vertically toward the clamping and positioning port and has one end corresponding to be inserted into the insertion notch. The auxiliary conveying roller is rotatably mounted on the hinge frame.

At the same time, it uses a close-fitting method to clamp the paper tube, which can accurately clamp the tubular parts and transport them axially. It also prevents deformation and damage caused by the squeezing force on the outer wall of the paper tube. Attached Figure Description

Detailed Implementation

[0025] Example 1

[0026] Please see Figures 1 to 3 This is a schematic diagram of a clamping and conveying mechanism and a fully automatic pipe cutting machine provided by this utility model. The clamping and conveying mechanism includes: a frame 10, an auxiliary lifting device 810 mounted on the frame 10, a lower adjusting device 820, an upper adjusting device 830, and a clamping and conveying device 840 mounted on the auxiliary lifting device 810. It is conceivable that this clamping and conveying mechanism also includes other functional components and specific structures, such as electrical connection components, control components, and installation structures, all of which are well-known to those skilled in the art and will not be described in detail here.

[0027] It should be noted that this clamping and conveying mechanism is suitable for cutting tubular structures, especially round tubes such as paper tubes or plastic tubes that undergo elastic deformation after being subjected to force on their outer wall. In this embodiment, a paper tube will be used as an example for detailed explanation.

[0028] The frame 10 has a rectangular frame structure, serving as a carrier for all components and facilitating assembly. In this embodiment, the length direction of the frame 10 is defined as the paper tube conveying direction. An opening is provided on the frame 10 to allow the paper tube to pass through axially.

[0029] The auxiliary lifting device 810 includes two auxiliary lifting guide rails 812 spaced apart on the frame 10, an auxiliary conveyor frame 811 slidably mounted on the auxiliary lifting guide rails 812 at both ends, and an auxiliary lifting cylinder 813 mounted on the frame 10. The auxiliary lifting cylinder 813 drives the auxiliary conveyor frame 811 to move vertically up and down along the auxiliary lifting guide rails 812. The auxiliary lifting device 810 outputs the clamping and conveying mechanism to the working position, and can also rise without being activated to avoid interference from component movement.

[0030] The lower adjustment device 820 includes two lead screw nuts 821 symmetrically rotatably mounted on both sides of the auxiliary conveyor frame 811. The lead screw nuts 821 are mounted on the auxiliary conveyor frame 811 via bearings. A lead screw lifting rod 822, which is threadedly connected to the lead screw nut 821, is installed in each lead screw nut 821. A lower adjustment frame 823 is provided between the two lead screw lifting rods 822 and at one end away from the auxiliary conveyor frame 811. The height of the lower adjustment frame 823 can be adjusted by rotating the lead screw nuts 821. The two lead screw lifting rods 822 are vertically guided by each other. A transmission gear 824 is sleeved on the outside of the lead screw nut 821 and fixed on the lead screw nut. A gear driver 825 is provided on the auxiliary conveyor frame 811 to synchronously drive the two transmission gears 824. This structural design avoids interference between the lower adjustment device 820 and the upper adjustment device 830.

[0031] Optimally, the auxiliary conveyor frame 811 is provided with a transverse guide groove 814 arranged along its length. A sliding mounting plate 815, which slides along the transverse guide groove 814, is provided at the upper end of the auxiliary conveyor frame 811. A mounting extension 816, protruding from the auxiliary conveyor frame 811, is provided on one side of the sliding mounting plate 815. Both the lower adjusting device 820 and the upper adjusting device 830 are connected to the mounting extension 816. The transverse positions of the lower adjusting device 820 and the upper adjusting device 830 are adjusted by the sliding mounting plate 815. The mounting extension 816 prevents interference between the lower adjusting device 820 and the upper adjusting device 830 and the auxiliary conveyor frame 811, eliminating the need for the slotted structure of the auxiliary conveyor frame 811.

[0032] Specifically, the gear actuator 825 includes two gear shafts 825a hinged to the sliding mounting plate 815 and respectively meshing with the transmission gear 824, a coupling 825b connecting the two gear shafts 825a, and a synchronous actuator 825c driving the gear shafts 825a to rotate. The gear shafts 825a have a diameter similar to the transmission gears 824 and are short shafts, making them easier to mesh stably with the transmission gears 824. Synchronous rotation of the two gear shafts 825a is achieved through the coupling 825b. The synchronous actuator 825c can be manually driven or driven by a motor.

[0033] The upper adjustment device 830 includes an adjustment cylinder 831 mounted on the auxiliary conveyor frame 811, an upper adjustment frame 832 mounted at the output end of the adjustment cylinder 831 and located above the lower adjustment frame 823, and vertical guide column structures 833 passing through both sides of the auxiliary conveyor frame 811 and the upper adjustment frame 832. The upper adjustment frame 832 is driven vertically by the adjustment cylinder 831. The length of the upper adjustment frame 832 is less than the distance between the two lead screw lifting rods 822 to prevent interference in lifting displacement.

[0034] The clamping and conveying device 840 includes auxiliary conveying rollers 841 that are spaced apart at the bottom of the upper adjusting frame 832 and the upper end of the lower adjusting frame 823. The auxiliary conveying rollers 841 are hinged together. The receiving grooves 842 on the outer circumferential wall of the auxiliary conveying rollers 841 and the receiving grooves 842 between the vertically spaced auxiliary conveying rollers 841 together form a clamping and positioning port 843. During operation, the lower adjusting device 820 is first adjusted so that the receiving groove of the lower auxiliary conveying roller 841 is attached to the outer wall of the paper tube. Then, the stroke of the upper adjusting frame 832 is adjusted by setting a limiting part in the vertical guide column structure 833. The paper tube is clamped in the same way. This allows for precise axial conveying of the tubular parts after clamping, and also prevents deformation and damage caused by the squeezing force on the outer wall of the paper tube.

[0035] Both the upper adjusting frame 832 and the lower adjusting frame 823 are provided with insertion notches 844 and hinge frames 845 extending vertically towards the clamping and positioning port 843. One end of the hinge frame 845 is inserted into the insertion notch 844 and fixed by a fastening structure to achieve a detachable connection. The auxiliary conveying roller 841 is rotatably mounted on the hinge frame 845. The protruding auxiliary conveying roller 841 provides more space for the clamping and positioning port 843 and reduces the likelihood of interference with other components. Optimally, the hinge frame 845 has an L-shaped or U-shaped cross-section, and the auxiliary conveying roller 841 is centrally positioned between the upper adjusting frame 832 and the lower adjusting frame 823. This increases the installation stability of the hinge frame 845, prevents corresponding deviations between the vertically spaced auxiliary conveying rollers 841, and improves clamping accuracy.
