Description

Technical Field

[0001] The utility model belongs to the technical field of cloth surface punching equipment, in particular to a cloth surface punching optimization equipment. Background Art

[0002] At present, folding beds, travel beds or folding chairs often use cloth as the bed surface, and a number of through holes are opened on the outer edge of the bed surface, and the bed surface is fixed to the bed frame by passing the rope through the through holes. The installation holes of the cloth surface are usually formed by a punching device. Usually, the punching position of the cloth surface is the two sides of the length direction of the cloth surface, and the holes are punched near the two ends of the cloth surface. The middle part is usually the hinge position of the middle part of the folding bed or travel bed, so the two sides in the middle are usually not punched.

[0003] Existing punching equipment uses a belt pulley to transport the fabric unit, and punches holes after reaching the designated position, and then stops at the middle position to punch holes again, thus completing the punching operation. However, the punching positions preset by the punching equipment are usually fixed, and the fabric units may be uneven, such as the end of the fabric unit is tilted, the length of the fabric unit is too long, or the fabric length is too short, which will cause the holes to be misplaced, the punching position is too short from the end, or the holes are punched to the outer end of the fabric end or partially, which will cause the fabric to be unable to be installed and used normally, and become a defective product. Summary of the invention

[0004] The purpose of the utility model is to solve the above-mentioned problems and to provide a cloth surface punching optimization device, which can punch holes in cloth surfaces of different lengths, ensure the normal installation and use of the cloth surface, and reduce the scrap rate.

[0027] The present invention will be further described below with reference to the accompanying drawings. Figure 1 — Figure 4 :

[0028] A cloth punching optimization device includes a transport platform 1, on which a conveyor belt 10 for moving the cloth is driven by a driving device, a processing table 2 is arranged on the front and rear sides of the conveyor belt 10, a slide rail 20 with the same length direction as the conveyor belt 10 is arranged above the processing table 2, and more than two groups of punching machines are slidably arranged on the slide rail 20, and servo motors 21 for driving the punching machines to slide along the slide rail 20 are respectively fixed on both sides of the processing table 2, a first light control sensor 40 is fixed on the front and rear sides of the feeding end of the transport platform 1, and a second light control sensor 41 is fixed on the front and rear sides of the transport platform 1 near the feeding end of the processing table 2.

[0029] During the implementation process, the first light control sensor can observe the initial state of the cloth unit when it is transported to the device, that is, whether there is any tilt or notch at the end of the cloth unit, and the second light control sensor can read the overall length of the cloth unit; the above-mentioned measuring servo motor is used to drive and adjust the punching position of the cloth unit.

[0030] The solution to the problem of punching holes is that the punching equipment usually starts to punch holes gradually from both sides of the fabric unit, and pauses when it reaches the middle folding position, and then performs the punching operation after a preset time. For fabric units with appropriate length and no tilt at the ends, the time of the middle folding is relatively fixed, and perfect punching can be achieved. However, the reality is that fabric units are often uneven, and the ends may be tilted or of different lengths. An effective solution is to control the pause time of the middle folding position to address the problem of different lengths, and the two light control sensors can measure the length, thereby facilitating the control of the middle folding time. If the fabric unit is shorter, the pause time of the middle folding position is shorter, ensuring that subsequent punching will not extend out of the fabric unit; if the fabric unit is longer, the opposite is true. Regarding the problem of end tilt, since the first and second light control sensors are arranged front and back, they can effectively detect the problem of end tilt, and then control the time of the punching base on the front and back sides respectively, and the distance fine-tuning is adjusted by the servo motor 21.

[0031] Usually, if there are both length problems and end tilt problems, the above operations are performed at the same time.

[0032] It is worth mentioning that the punching positions on the front and back sides do not have to be vertically aligned, because the cloth is fixed to the bed frame by ropes, as long as there are no holes punched outside the cloth or missing holes.

[0033] The above structural method has a simple mechanical structure and is convenient for modification of traditional cloth covering equipment, which greatly improves the cloth surface punching operation and ensures the qualified rate.

[0034] Preferably, three groups of punching machines are arranged on the processing table 2, namely a first punching machine 30, a second punching machine 31 and a third punching machine 32. The second punching machine 31 is fixed on the slide rail 20, and the first punching machine 30 and the third punching machine 32 are located on both sides of the second punching machine 31, and are respectively connected to the servo motors 21 at both ends of the processing table 2 through screw rods.

[0035] During the implementation process, the second punching machine 31 remains fixed on the slide rail, which not only ensures that the punching machines on both sides do not slide excessively, but also greatly improves the punching efficiency.

[0036] Preferably, a limiting slide plate 33 is fixed on the second punching machine station 31, a strip sliding hole 330 is opened on the limiting slide plate 33, and the strip sliding hole 330 is parallel to the slide rail 20, and a sliding column 300 is fixed on the first punching machine station 30 to penetrate into the strip sliding hole 330. When the first punching machine station 30 is driven by the servo motor 21 and slides on the slide rail 20, the sliding column 300 slides in the strip sliding hole 330.

[0037] In the above structure, the setting of the limiting slide plate 33 can prevent the first punching machine 30 from sliding out of the range of the strip slide hole 330 during the sliding process, so that the spacing is kept within the effective range during the spacing adjustment process.

[0038] Preferably, the punching machine comprises a punching frame 340 , on which a punching cylinder 341 is disposed, on which a punching knife 342 is fixed to a piston rod of the punching cylinder 341 , and below which a knife seat 343 is disposed.

[0039] Preferably, a material discharge box 35 is provided on one side of the knife seat 343 , and a material discharge pipe is connected to one side of the material discharge box 35 , and a discharge port of the material discharge pipe is located above the knife seat 343 .

[0040] During the implementation process, the punching machine is not only used for drilling holes, but also requires the placement of punching rings to facilitate threading ropes and tying them to the bed frame.

[0041] Preferably, a material pressing rack 11 is arranged above the transport platform 1, a material pressing track is arranged on the material pressing rack 11, a material pressing cylinder is slidably arranged on the material pressing track, and a cloth pressing block 12 for covering and pressing the cloth surface is fixed to the lower end of the piston rod of the material pressing cylinder.

[0042] In the above structure, the cloth pressing block 12 can stabilize the cloth unit during transportation, thus ensuring accurate and efficient punching.

[0043] Preferably, the first light control sensor 40 and the second light control sensor 41 are both arranged vertically. The light control sensors arranged vertically can accurately identify the end positions of the fabric unit to ensure accurate punching.

[0044] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
