Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of safety rope processing, and in particular to a safety rope processing preparation quantitative cutting machine. BACKGROUND

[0002] In the safety rope processing preparation process, the safety rope raw material in roll form needs to be accurately cut into segments according to the preset length to meet the needs of different scenes for safety rope specifications. There are currently devices for safety rope quantitative cutting in the industry, such as the safety rope processing preparation quantitative cutting machine disclosed in Chinese patent CN222972305U, which realizes the clamping, traction stretching and quantitative cutting of safety rope through the cooperation of the workbench, cutting device, clamping mechanism and traction mechanism, to a certain extent, solving the problems of insufficient tightness and poor adaptability of traditional cutting.

[0003] However, the existing patent still has obvious deficiencies: first, the cutting operation is mainly for single safety rope, and lacks a structure design suitable for synchronous processing of multiple safety ropes. Single cutting can only handle a single rope, and the production efficiency is low, which cannot meet the requirements of processing speed in batch production scenarios; second, it does not set up a special automatic unloading and collecting mechanism, and the safety rope after cutting needs to be taken out and arranged by manual operation, which not only increases the labor cost, but also easily causes the safety rope after cutting to pile up and entangle due to manual intervention, affecting the continuity of the subsequent processing process; third, it only relies on the movement distance of the traction mechanism to indirectly control the cutting length, and does not equip a special length detection and feedback adjustment component, which cannot monitor the actual extension length of the safety rope in real time and make dynamic correction, and is prone to cause poor length consistency of the safety rope after cutting due to mechanical errors of the traction mechanism (such as screw transmission gap and traction block movement deviation). Therefore, in view of the above status, it is urgent to develop a safety rope processing preparation quantitative cutting machine that can realize synchronous cutting of multiple safety ropes through multiple support shaft protrusions, multiple cutting mechanism slots and multiple end clamping mechanism positioning slots, improve efficiency, accurately control the cutting length with the help of laser ranging sensor and PLC controller, loosen the rope with the end clamping mechanism after cutting, press the rope down with the pressing plate of the unloading mechanism, and then fall into the material collecting box through the discharge slot for automatic collection of materials, so as to reduce manual operation and overcome the deficiencies in current actual application to meet the current needs.

[0008] Preferably, the supporting table is provided with a groove for the insertion of the cutting tool.

[0009] Preferably, the laser ranging sensor is arranged opposite to the cutting tool.

[0010] Preferably, the transverse moving mechanism comprises a transmission roller, a transmission belt, a first motor and an adapter block, the number of the transmission rollers is two, the transmission rollers are rotationally connected to the workbench, the transmission rollers are transmissionally connected through the transmission belt, the first motor is fixed on the workbench, the output shaft of the first motor is connected with one transmission roller through a shaft coupling, the adapter block is fixedly installed on the upper half of the transmission belt, and the transmission belt is connected with the end clamping mechanism.

[0011] Preferably, a plurality of casters are installed at the bottom of the material collecting box, and the casters are provided with foot brakes.

[0016] The beneficial effects of this invention are as follows: When using the quantitative cutting machine for processing safety ropes, the operator first sets the required cutting length on the PLC controller. Then, multiple safety rope coils are respectively fitted onto the outside of multiple bosses and clamped with anti-slip rubber sleeves. The anti-slip rubber sleeves increase the friction between the safety rope coils and the bosses, allowing the safety rope coils and support shaft to rotate synchronously. Next, multiple safety ropes are passed through multiple through slots and placed into positioning slots, ensuring the rope ends are aligned with the sealed end of the positioning slot. Then, a second motor drives the transmission shaft and eccentric cam to rotate downwards by 90°, causing the eccentric cam to press the safety rope ends in the positioning slots. Finally, a first motor drives the transmission roller and transmission belt to rotate, which in turn moves the adapter block. The connecting block drives the end clamping mechanism to move, which in turn moves the safety rope forward. A laser rangefinder sensor monitors the distance between the rope end and the cutting blade in real time. Once the set distance is reached, the first motor stops. Then, the first hydraulic cylinder drives the cutting blade to move downward, cutting the safety rope. Next, the second motor drives the drive shaft and eccentric cam to rotate upward by 90°, causing the eccentric cam to release the rope end. The cut rope slides down under gravity. Simultaneously, the second hydraulic cylinder drives the lower pressure plate to move downward, pressing down the safety rope to ensure that the cut safety rope completely passes through the discharge chute and falls into the collection box for collection. Finally, the lateral movement mechanism drives the end clamping mechanism back to its original position, ready for the next cutting operation. This process is repeated. In summary, this invention enables the simultaneous cutting of multiple safety ropes through multiple bosses on the support shaft, multiple through slots in the cutting mechanism, and multiple positioning slots in the end clamping mechanism, thereby improving efficiency. It also relies on a laser rangefinder and a PLC controller to precisely control the cutting length. After cutting, the end clamping mechanism loosens the rope, and the lower plate of the assist feeding mechanism presses the rope down, allowing it to fall into the receiving box via the discharge chute for automatic material collection and reduced manual operation.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Specific implementation examples are given below.

[0031] See ​ In this embodiment of the invention, a quantitative cutting machine for processing and manufacturing safety ropes includes a workbench 1, a support shaft 2, a cutting mechanism 3, a transverse mechanism 4, an end clamping mechanism 5, an auxiliary feeding mechanism 6, and a receiving box 7. The support shaft 2 is rotatably connected to the right end of the workbench 1. The support shaft 2 is used to support the safety rope rolls to be cut. Multiple bosses 201 are fixed on the support shaft 2. Anti-slip rubber sleeves 202 are fixed on the outer side of the bosses 201. In use, multiple safety rope rolls are respectively put on the outer side of the multiple bosses 201 and the anti-slip rubber sleeves 202 are clamped. The anti-slip rubber sleeves 202 increase the friction between the safety rope rolls and the bosses 201, so that the safety rope rolls and the support shaft 2 can rotate synchronously.

[0032] The cutting mechanism 3 is located on the left side of the support shaft 2 and installed on the workbench 1. The cutting mechanism 3 is used to cut safety ropes. The cutting mechanism 3 includes: a support platform 301, a through groove 302, a first hydraulic cylinder 303, and a cutting blade 304. The support platform 301 is fixed on the workbench 1. Multiple through grooves 302 are evenly distributed on the support platform 301 for the safety rope to pass through. Two first hydraulic cylinders 303 are fixed on the support platform 301. The telescopic ends of the first hydraulic cylinders 303 are fixed to the cutting blade 304. The support platform 301 is provided with a groove 3011 for the cutting blade 304 to be inserted. In use, the safety rope is passed through the through groove 302, and the first hydraulic cylinder 303 drives the cutting blade 304 to move down, cutting the safety rope. The groove 3011 allows the cutting blade 304 to move down to a deeper position to completely cut the safety rope.

[0033] The end clamping mechanism 5 is located on the left side of the cutting mechanism 3 and is connected to the transverse movement mechanism 4. The transverse movement mechanism 4 is installed on the workbench 1. The end clamping mechanism 5 is used to clamp the head of the safety rope, and the transverse movement mechanism 4 is used to drive the end clamping mechanism 5 to move laterally.

[0034] The transverse movement mechanism 4 includes: a transmission roller 401, a transmission belt 402, a first motor 403, and an adapter block 404. There are two transmission rollers 401, which are rotatably connected to the worktable 1. The two transmission rollers 401 are connected by the transmission belt 402. The first motor 403 is fixed on the worktable 1. The output shaft of the first motor 403 is connected to one of the transmission rollers 401 through a coupling. The adapter block 404 is fixedly installed on the upper half of the transmission belt 402. The transmission belt 402 is connected to the end clamping mechanism 5. In use, the first motor 403 drives the transmission rollers 401 and the transmission belt 402 to rotate. The rotation of the transmission belt 402 drives the adapter block 404 to move. The adapter block 404 drives the end clamping mechanism 5 to move.

[0035] The end clamping mechanism 5 includes: a frame 501, a slider 502, a guide rail 503, a positioning block 504, a positioning groove 505, a laser rangefinder 506, a second motor 507, a transmission shaft 508, and an eccentric cam 509. The frame 501 is fixed to the adapter block 404. Two sliders 502 are fixed to the bottom of the frame 501, and each slider 502 is slidably mounted on a guide rail 503. The guide rail 503 is fixed to the worktable 1. Multiple positioning blocks 504 are fixed on the frame 501. Each positioning block 504 has a positioning groove 505. The positioning groove 505 is open at one end and closed at the other. The open end is used for the safety rope end to enter, and the closed end is used to position the front end of the safety rope end. A laser rangefinder 506 is fixedly mounted on the frame 501. The starting detection end of the laser rangefinder 506... The laser range sensor 506 is flush with the sealing end of the positioning groove 505 and is positioned opposite the cutting tool 304 to detect the distance between the cutting tool 304 and the sealing end of the positioning groove 505. This distance is the actual length of the safety rope cut. The drive shaft 508 is rotatably connected to the frame 501. Multiple eccentric cams 509 are fixed on the drive shaft 508, and each eccentric cam 509 is aligned with a positioning groove 505. The second motor 507 is fixed to the frame 501, and the output shaft of the second motor 507 is fixed to the drive shaft 508 through a coupling. In use, the head of the safety rope is first inserted into the positioning groove 505 and aligned with the sealing end of the positioning groove 505. Then, the second motor 507 drives the drive shaft 508 and the eccentric cams 509 to rotate downward by 90°, so that the eccentric cams 509 press the safety rope head in the positioning groove 505 tightly.

[0036] The workbench 1 is provided with a discharge trough 101. A receiving box 7 is placed on the ground below the discharge trough 101. An auxiliary feeding mechanism 6 is installed on the workbench 1 above the discharge trough 101. After cutting, the cut safety rope is pushed downward by the auxiliary feeding mechanism 6 so that the safety rope completely passes through the discharge trough 101 and falls into the receiving box 7.

[0037] The bottom of the receiving box 7 is equipped with multiple casters 701, each caster 701 having a foot brake, so as to move or fix the receiving box 7.

[0038] The auxiliary feeding mechanism 6 includes a second hydraulic cylinder 601 and a lower pressure plate 602. The second hydraulic cylinder 601 is fixed on the workbench 1. The telescopic end of the second hydraulic cylinder 601 is fixed to the lower pressure plate 602. In use, the second hydraulic cylinder 601 drives the lower pressure plate 602 to move down, and the lower pressure plate 602 presses down the safety rope.

[0039] A miniature hydraulic station 8 and a PLC controller 9 are installed on one side of the workbench 1 on the ground. The first hydraulic cylinder 303 and the second hydraulic cylinder 601 are connected to the miniature hydraulic station 8 through oil supply pipes (not shown). The miniature hydraulic station 8 supplies hydraulic oil to the first hydraulic cylinder 303 and the second hydraulic cylinder 601 to drive their operation. The first motor 403, the laser rangefinder 506, the second motor 507, the second hydraulic cylinder 601, and the miniature hydraulic station 8 are all electrically connected to the PLC controller 9 and are electrically controlled by the PLC controller 9. The PLC controller 9 is equipped with a display screen and operation buttons. The display screen can show the data detected by the laser rangefinder 506, and the operation buttons can be set by the user.

[0040] Working Principle: When using this quantitative cutting machine for safety rope processing, the operator first sets the required cutting length on the PLC controller 9. Then, multiple safety rope coils are respectively placed on the outside of multiple bosses 201, and the anti-slip rubber sleeves 202 are clamped. The anti-slip rubber sleeves 202 increase the friction between the safety rope coils and the bosses 201, allowing the safety rope coils and support shaft 2 to rotate synchronously. Next, multiple safety ropes are passed through multiple through slots 302 and placed into positioning slots 505, ensuring the rope ends are aligned with the sealed end of the positioning slot 505. Then, the second motor 507 drives the transmission shaft 508 and eccentric cam 509 to rotate downwards by 90°, causing the eccentric cam 509 to press the safety rope ends in the positioning slot 505. Finally, the first motor 403 drives the transmission roller 401 and transmission belt 402 to rotate. The rotation of the transmission belt 402 drives the transition block 404 to move, thus... Block 404 drives the end clamping mechanism 5 to move, which in turn moves the safety rope forward. The distance between the rope end and the cutting blade 304 is monitored in real time by the laser range sensor 506. Once the set distance is reached, the first motor 403 stops. Then, the first hydraulic cylinder 303 drives the cutting blade 304 to move downward, cutting the safety rope. Next, the second motor 507 drives the transmission shaft 508 and the eccentric cam 509 to rotate upward by 90°, causing the eccentric cam 509 to loosen the rope end. The cut rope slides down by gravity. At the same time, the second hydraulic cylinder 601 drives the lower pressure plate 602 to move downward, pressing the safety rope down to ensure that the cut safety rope completely passes through the discharge chute 101 and falls into the collection box 7 for collection. Finally, the lateral movement mechanism 4 drives the end clamping mechanism 5 back to its original position for the next cutting operation. This process is repeated.
