Description

Technical Field

[0001] This utility model belongs to the technical field of composite carpet production equipment, specifically relating to a carpet storage device. Background Technology

[0002] The production of composite carpets mainly involves uniformly sprinkling hot melt powder (EVA) onto the carpet using powder rollers, knives, and sieves. After sprinkling EVA onto the bottom layer of carpet, the hot melt powder is baked in an oven until it reaches a molten state. Then, it is pressed together with another layer of carpet to finally produce the composite carpet.

[0003] Existing carpet storage devices mostly employ passive unwinding and mechanical correction, which suffers from problems such as large tension fluctuations and low correction accuracy. This causes the carpet to easily shift or wrinkle during the lamination and cutting processes, affecting the quality of the finished product. Although some equipment has introduced servo correction, it lacks multi-layer collaborative control, and the synchronization between the storage and cutting processes is insufficient, resulting in low efficiency. Summary of the Invention

[0004] To address the aforementioned problems, this utility model discloses a carpet storage device. An automatic servo correction device corrects the carpet entry point, while a servo electric correction mechanism detects the offset using a photoelectric sensor. An electric push rod drives a guide roller to correct the carpet's direction of travel, thus correcting the exit point of the storage rack. This achieves constant tension control during carpet storage, ensuring stable carpet quality and reducing deformation and defects caused by tension fluctuations.

[0005] To achieve the above objectives, the specific technical solution of this application is as follows:

[0006] A carpet storage device, comprising:

[0007] The fabric dropper includes a multi-layer folding guide plate, a vibration motor, and a Teflon-coated guide surface. The multi-layer folding guide plate is arranged in a stepped manner, and the vibration motor is installed at the bottom of the fabric dropper.

[0008] The active traction mechanism includes a motor, a traction roller assembly, and a synchronous belt drive module. The motor drives the traction roller assembly to clamp the carpet via the synchronous belt.

[0009] An automatic servo correction device includes a correction probe, a servo motor, a correction roller assembly, and a coupling. The correction probe is a photoelectric sensor installed on both sides of the fabric dropper entrance. The servo motor drives the correction roller assembly to move laterally through the coupling.

[0010] The floating roll tension control system includes a floating roll, a tension sensor, a proportional valve, and a second cylinder. The floating roll is hinged to the frame via the second cylinder. The tension sensor detects the displacement of the floating roll in real time and feeds it back to the PLC controller. The proportional valve dynamically adjusts the pressure of the second cylinder.

[0011] The automatic code counting module, integrated into the motor encoder, calculates the feeding length through the PLC controller and triggers the joint signal in conjunction with the storage rack;

[0012] The storage rack includes a pressure sensor, a third cylinder, and a servo-electric correction mechanism. The pressure sensor detects the stacking height of the storage materials and controls the third cylinder to adjust the height of the storage rack. The servo-electric correction mechanism includes a correction photoelectric sensor, an electric push rod, and a guide roller. The correction photoelectric sensor is installed at the outlet end of the storage rack to detect the offset of the carpet edge and drive the electric push rod to adjust the angle of the guide roller.

[0013] The traction roller assembly includes an upper roller and a lower roller. The upper roller is pressed and separated by a first cylinder, and the surface of the lower roller is provided with grooves.

[0014] The vibration motor of the fabric dropper is connected to the fabric dropper via an elastic pad.

[0015] The automatic servo correction device includes two parallel rollers and one angle adjustment roller. The angle adjustment roller is driven to rotate by a servo motor to correct the carpet travel angle.

[0016] Preferably, in the servo-electric correction mechanism of the storage rack, the surface of the guide roller is covered with a polyurethane layer with a thickness of 3-5mm.

[0017] Compared with the prior art, the beneficial effects of this application are as follows:

[0018] This application achieves carpet feeding rack inlet correction through an automatic servo correction device. The servo electric correction mechanism detects the offset through a photoelectric sensor, and the electric push rod drives the guide roller to correct the carpet's travel direction to achieve carpet feeding rack outlet correction. This achieves constant tension control during carpet feeding, ensuring stable carpet quality and reducing deformation and defects caused by tension fluctuations.

[0019] The floating roller controls the cylinder pressure through a proportional valve, and the tension sensor detects the displacement in real time and feeds it back to the PLC to form a closed-loop control, thus completing the dynamic adjustment of the floating roller. The surface of the traction roller group is covered with a silicone layer, and the groove design of the lower roller increases friction to prevent slippage and achieve tension control.

[0020] Multi-layered folding guide plates reduce carpet sliding resistance, and a high-frequency vibration motor is installed at the bottom of the carpet drop rail to prevent carpet stacking and jamming. Attached Figure Description

[0033] The automatic servo correction device 3 is located on both sides of the fabric dropper 1, and includes a correction probe 31, a servo motor, a correction roller group 33, and a coupling 34. The correction probe 31 is a photoelectric sensor, which is installed on both sides of the inlet end of the fabric dropper and has a detection accuracy of ±0.1mm. The servo motor drives the correction roller group 33 to move laterally through the coupling 34, with a stroke of ±50mm and a moving speed of 10-50mm / s.

[0034] like Figure 4 As shown, the floating roller tension control system 4 includes a floating roller 41, a tension sensor 42, a proportional valve 43, and a second cylinder 44. The floating roller 41 is hinged to the frame through the second cylinder 44. The tension sensor 42 detects the displacement of the floating roller in real time and feeds it back to the PLC controller 45. The proportional valve 43 dynamically adjusts the pressure of the second cylinder 44, and the tension fluctuation range is ≤5N.

[0035] The automatic code counting module 5 is integrated with the encoder 51 of the motor 21. The encoder resolution is 1000 pulses / revolution. The PLC controller 45 calculates the feeding length with an error of ≤0.1m and triggers the connector signal in conjunction with the storage rack 6.

[0036] The storage rack 6 includes a pressure sensor 61, a third cylinder 62, and a servo-electric correction mechanism 63. The pressure sensor 61 detects the stacking height of the stored materials and controls the third cylinder 62 to adjust the height of the storage rack.

[0040] Working principle:

[0041] From the drop bar to the active traction mechanism: After being folded by the traction mechanism, the carpet roll is fed to the drop bar. Inside the drop bar, multi-layered folded guide plates guide the carpet smoothly in. The active traction mechanism is located at the entrance end of the drop bar, and a motor-driven traction roller assembly lowers the carpet into the drop bar with constant tension.

[0042] After leaving the fabric dropper, the carpet enters the automatic servo correction device. The correction probe detects the edge position of the carpet in real time. Once a deviation is detected, the servo motor drives the correction roller group to make lateral adjustments to ensure the carpet is in the correct orientation.

[0043] Through the floating roller tension control system: After the carpet is corrected, it enters the floating roller tension control system. The floating roller floats up and down with the change of carpet tension. The tension sensor feeds the displacement data back to the PLC controller, which dynamically adjusts the cylinder pressure to maintain stable tension.

[0044] Reaching the Storage Rack: The carpet, after tension control, finally reaches the storage rack. The pressure sensor on the storage rack detects the carpet stacking height, controls the third cylinder to adjust the height of the storage rack, and the servo electric correction mechanism ensures that the carpet is accurately centered on the storage rack, completing the storage process.
