Description

Technical Field

[0001] This invention relates to the field of bag quality inspection equipment technology, specifically to a cutting device for luggage handles. Background Technology

[0002] A suitcase, also known as a rolling suitcase, is generally equipped with a retractable handle for easy pulling. The handle needs to be adjusted according to the size of the suitcase using a cutting device.

[0003] The problem with existing technology is that the tie rod component requires a telescopic structure, so it is processed using hollow tubular profiles. Given current consumer demand for slim and aesthetically pleasing designs, the profile wall thickness is minimized. However, during cutting, the cutting blade presses down on the outer circumference of the profile, and due to the hollow structure of the profile, defects such as dents and deformations occur around the cut, requiring secondary trimming of the cut profile before it can be used.

[0004] Therefore, if temporary support is provided inside the hollow tube during the cutting of the tie rod component, the area around the cut is structurally reinforced, preventing defects such as dents and deformations, which can significantly improve production quality and avoid additional costs incurred by secondary processing. Summary of the Invention

[0005] To address the shortcomings of the aforementioned technologies, this invention provides a cutting device for suitcase pull rods. The technical solution of this invention is as follows: A cutting device for suitcase pull rods includes a worktable, a cutting device, a lifting device, a limiting block, an insert rod, and a driving mechanism. The worktable is provided with a first guide rail, a cutting station, and an entrance side. The limiting block has a lockable sliding engagement with the first guide rail. The limiting block has a through-hole facing the entrance side, the outline size of which matches the outline size of the hollow hole of the pull rod and is smaller than the outline size of the pull rod. The insert rod includes a supporting end that matches the outline size of the hollow hole of the pull rod. The driving mechanism is provided with… On the other side of the limiting block opposite the entrance side, and in conjunction with the insert rod, the supporting end is driven to pass through the through-hole and enter the hollow hole of the pull rod. The supporting end moves to the cutting station to support the inner wall of the hollow hole of the pull rod. The limiting block adjusts the distance between itself and the cutting station along the first guide rail according to the required cutting length of the pull rod. The lifting device is in conjunction with the cutting device to drive the cutting device to move closer to or away from the cutting station. Further features of this utility model: The supporting end of the insert rod is provided with an air expansion shaft, which expands to support the hollow inner wall of the pull rod.

[0006] Further features of this invention: The insert rod is provided with a central through hole, and the central through hole has a telescopic hole radially provided at the support end. The device also includes an expansion member, a driving cylinder, and a push rod. The expansion member includes a support part, a sliding shaft part, and a wedge-shaped slider part that are adapted to the contour of the hollow hole of the pull rod. The support part is located on the outside of the support end. The sliding shaft part is slidably engaged with the telescopic hole. The wedge-shaped slider part is located on the inside of the central through hole. The push rod is inserted into the central through hole from the direction away from the inlet side. The push rod is provided with a conical head that is slidably engaged with the wedge-shaped slider part and a connecting part that is linked to the driving cylinder. The driving cylinder drives the push rod to penetrate axially into the central through hole, pushes the wedge-shaped slider part to drive the support part to expand radially outward to support the pull rod, and the driving cylinder drives the push rod to withdraw axially from the central through hole. The support part falls radially back under gravity.

[0007] A further feature of this invention is that the driving mechanism includes a sliding seat, a lead screw, a lead screw seat, and a lead screw motor.

[0008] The lead screw seat is provided with a second guide rail parallel to the first guide rail. The sliding seat is slidably engaged with the second guide rod. The sliding seat is provided with a mounting sleeve aligned with the through-hole. The mounting sleeve is detachably threadedly engaged with the insert rod. The sliding seat is provided with an insertion hole concentric with the mounting sleeve. The drive cylinder is fixed on the sliding seat. The push rod passes through the insertion hole and is linked with the drive cylinder. The bottom of the sliding seat is provided with a lead screw nut seat. The lead screw is rotatably engaged with the sliding seat and is linked with the lead screw motor. The lead screw motor drives the support end to move to the cutting position or to retract the pull rod or retract from the through-hole.

[0009] A further feature of this invention is that a guide roller is rotatably mounted on the inlet side.

[0010] A further feature of this invention is that a plurality of linear guide rail limiting blocks are slidably disposed on the first guide rail, and these plurality of linear guide rail limiting blocks lock the position of the limiting block.

[0011] Further features of this invention: The cutting device includes a cutting blade, a base, a motor, a transmission mechanism, a dust extraction fan, and a hood facing the cutting blade.

[0012] The beneficial effects of this utility model are as follows: The distance between the limiting block and the cutting station is adjusted according to the required length of the pull rod. The locking position of the limiting block by the linear guide rail ensures fixation during cutting. The profile is pushed in by the inlet side guide roller, aligning the hollow hole of the pull rod profile with the through-hole contour. Since the wall thickness of the pull rod is greater than that of the through-hole, it abuts against the limiting block. Then, the drive mechanism controls the insertion rod to move to the cutting station according to the corresponding cutting length. Support is provided inside the hollow tube during pull rod component cutting, thus strengthening the structure around the cut and preventing defects such as dents and deformation. This significantly improves production quality and avoids additional costs associated with secondary processing. Attached Figure Description

Detailed Implementation

[0019] like Figure 1-2As shown, a cutting device for a suitcase pull rod 8 includes a worktable 1, a cutting device 2, a lifting device 3, a limiting block 4, an insert rod 6, and a driving mechanism 7. The worktable 1 is provided with a first guide rail 11, a cutting station 12, and an entrance side 13. The limiting block 4 is in a lockable sliding engagement with the first guide rail 11. The limiting block 4 has a through-hole 41 facing the entrance side 13. The outline size of the through-hole 41 is adapted to the outline size of the hollow hole 81 of the pull rod 8, but smaller than the outline size of the pull rod 8. The insert rod 6 includes a wheel that engages with the hollow hole 81 of the pull rod 8. The support end 61 is adapted to the profile size. The drive mechanism 7 is located on the other side of the limiting block 4 opposite to the entrance side 13 and is linked with the insertion rod 6. The drive support end 61 passes through the through-hole 41 and enters the hollow hole 81 of the pull rod 8. The support end 61 moves to the cutting station 12 to support the inner wall of the hollow hole 81 of the pull rod 8. The limiting block 4 adjusts the distance between itself and the cutting station 12 along the first guide rail 11 according to the required cutting length of the pull rod 8. The lifting device 3 is linked with the cutting device 2 to drive the cutting device 2 to move closer to or away from the cutting station 12.

[0020] The support end 61 of the insert rod 6 is provided with an air expansion shaft, which expands to support the hollow inner wall of the tie rod 8.

[0021] The insert rod 6 is provided with a central through hole 62, and a telescopic hole 63 is provided radially at the support end 61 of the central through hole 62. The device also includes an expansion member 64, a drive cylinder 65, and a push rod 66. The expansion member 64 includes a support part 641, a sliding shaft part 642, and a wedge-shaped slider part 643 that are adapted to the contour of the hollow hole 81 of the pull rod 8. The support part 641 is provided on the outside of the support end 61, the sliding shaft part 642 slides in cooperation with the telescopic hole 63, and the wedge-shaped slider part 643 is provided at the central through hole 62. Inside the hole 62, the push rod 66 is inserted into the central through hole 62 from the direction away from the inlet side 13. The push rod 66 is provided with a conical head that slides with the wedge-shaped slider part 643 and a connecting part that is linked with the drive cylinder 65. The drive cylinder 65 drives the push rod 66 to penetrate the central through hole 62 axially, pushes the wedge-shaped slider part 643 to drive the support part 641 to expand radially outward to support the tie rod 8. The drive cylinder 65 drives the push rod 66 to withdraw from the central through hole 62 axially, and the support part 641 falls radially back under gravity.

[0022] The driving mechanism 7 includes a sliding seat 71, a lead screw 72, a lead screw seat 73, and a lead screw motor 74. The lead screw seat 73 is provided with a second guide rail 731 parallel to the first guide rail 11. The sliding seat 71 is slidably engaged with the second guide rod. The sliding seat 71 is provided with a mounting sleeve aligned with the through-hole 41. The mounting sleeve is detachably threadedly engaged with the insert rod 6. The sliding seat 71 is provided with an insertion hole concentric with the mounting sleeve. The driving cylinder 65 is fixed on the sliding seat 71. The push rod 66 passes through the insertion hole and is linked with the driving cylinder 65. The bottom of the sliding seat 71 is provided with a lead screw 72 nut seat. The lead screw 72 is rotatably engaged with the sliding seat 71 and is linked with the lead screw motor 74. The lead screw motor 74 drives the support end 61 to move to the cutting position 12 or to retract the pull rod 8 or to retract the through-hole 41.

[0023] The inlet side 13 is rotatably equipped with guide rollers.

[0024] A plurality of linear guide rail limiting blocks 42 are slidably disposed on the first guide rail 11, and the plurality of linear guide rail limiting blocks 42 lock the position of the limiting block 4.

[0025] The cutting device 2 includes a cutting blade, a base, a motor, a transmission mechanism, a dust extraction fan, and a hood facing the cutting blade.

[0026] The beneficial effects of this utility model are as follows: Based on the required length of the pull rod 8, the distance between the limiting block 4 and the cutting station 12 is adjusted. The position of the limiting block 4 is locked by the linear guide limit block 42, maintaining fixation during cutting. The profile is pushed in by the guide roller on the inlet side 13. The hollow hole 81 of the pull rod 8 profile aligns with the outline of the through opening 41, and since the wall thickness of the pull rod 8 is greater than that of the through opening 41, it abuts against the limiting block 4. Then, the drive mechanism 7 controls the insertion rod 6 to move to the cutting station 12 according to the cutting length. The support end 61, which is adapted to the contour of the hollow hole 81, directly abuts against the inner wall of the hollow hole 81, or expands against it through the air shaft, or uses the push rod 66 to penetrate and cooperate with the wedge-shaped slider part 643 to lift the support part 641. These are some of the embodiments that achieve support for the hollow hole 81 of the pull rod 8. In this way, when the pull rod 8 is cut, temporary support is provided inside the hollow tube. The structure around the cut is strengthened, so there will be no defects such as dents or deformation. This can significantly improve the production quality and avoid the additional costs caused by secondary processing.
