Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of edge band manufacturing, in particular to an edge band winding machine. BACKGROUND

[0002] After the furniture board is processed, the cross section is usually in a bare state, which is not only not beautiful, but also harmful gases (such as formaldehyde, benzene and other harmful gases) in the board will also be volatilized, and the bare cross section is also easy to wear; therefore, all furniture boards after processing need to use edge band to perform edge sealing treatment on the cross section. After the edge band is manufactured, printed, embossed and dried, etc., it must be wound for convenient packaging, storage and transportation. The current edge band winding equipment can only wind a single type or type of edge band in one use cycle, and the selection of the size type of the edge band winding head is bundled with the position parameter setting of the edge band traction device, in other words, the corresponding position parameters of the edge band traction device need to be set according to the size type of the selected edge band winding head, so that the edge band traction device can accurately pull the edge band to the outer diameter of the edge band winding head of the corresponding size type and clamp it to complete the traction feeding and prepare for the next winding operation; therefore, when winding different types of edge bands on the same winding equipment, the edge band winding head of the corresponding size type needs to be replaced, and the position parameters of the edge band traction device corresponding to the edge band winding head of the size type also need to be modified synchronously to meet the accurate feeding and clamping of the corresponding edge band, which generally takes several minutes or even longer to set parameters and debug, and the efficiency is relatively low. At the same time, when installing or replacing the edge band winding head of the original edge band winding equipment, the workers need to use a wrench to tighten the fastening screw to fix the edge band winding head on the winding lifting shaft, and use the wrench to loosen the fastening screw to remove it when disassembling. Obviously, the original installation and disassembly method of the edge band feeding and the edge band winding head is extremely troublesome and inefficient, and such long-time and high-frequency operation not only increases the fatigue intensity of the workers, but also seriously affects the winding efficiency of the edge band, is not conducive to the production cost control of the enterprise, and cannot effectively meet the current large-scale, large-batch and multi-type edge band winding requirements.

[0057] The main working principle of the application is: After the winding machine is powered on, the start switch button on the electric control box 6 is pressed, the edge strip winding head 57 is lowered and positioned in alignment with the rotating workbench surface 13, the position of the edge strip clamping part 577 and the edge strip feeding mechanism 2 are detected by the inductive probe 591, and the PLC controller in the electric control box 6 receives the alignment signal of the edge strip clamping part 577 and the edge strip feeding mechanism 2 returned by the inductive probe 591. After receiving the alignment signal of the edge strip clamping part 577 and the edge strip feeding mechanism 2 returned by the inductive probe 591, the PLC controller in the electric control box 6 controls the edge strip clamping cylinder of the edge strip traction device 24 to clamp the edge strip, controls the edge strip traction cylinder to send the edge strip clamped by the edge strip clamping cylinder to the outer diameter between the edge strip clamping part 577 and the edge strip winding head 57, and then controls the winding head clamping driving device to expand the winding wheel 576 of the edge strip winding head 57 to clamp the edge strip between the edge strip clamping part 577 and the outer diameter of the edge strip winding head 57. Then the PLC controller in the electric control box 6 controls the edge strip clamping cylinder to release the edge strip, controls the edge strip traction cylinder to start, and brings the edge strip clamping cylinder back to the original position. Then the PLC controller in the electric control box 6 controls the winding driving motor to start to drive the rotating workbench surface 13 to rotate and drive the edge strip winding head 57 to rotate together to wind the edge strip. The edge strip passes between a pair of edge strip thickness measuring rollers 22. If the joint of the edge strip passes, it will open the two pairs of edge strip thickness measuring rollers 22 by an angle. The angle sensor connected with the pair of edge strip thickness measuring rollers 22 senses the angle change in real time and transmits the angle signal to the PLC controller in the electric control box 6. When the angle reaches the set value on the PLC controller, it proves that the joint of the edge strip has passed. At this time, the PLC controller quickly issues an instruction to control the winding driving motor to stop working, so that the rotating workbench surface 13 stops rotating. Then the PLC controller controls the pair of edge strip shearing driving cylinders to drive the edge strip shears to descend and align with the joint position of the edge strip to cut off the joint. Then the PLC controller controls the winding head lifting driving cylinder 53 to lift the edge strip winding head 57 and completely separate from the rotating workbench surface 13. Finally, the PLC controller controls the edge strip pushing driving cylinder 42 to start, and the edge strip pushing driving cylinder 42 drives the pushing rod to push the wound edge strip product out of the rotating workbench surface 13, and a roll of edge strip product is wound.
