[0025] To solve the problems existing in the related prior art, the utility model provides a strip material continuous feeding device of coating machine, which will be described in detail below in combination with the drawings and embodiments.
[0026] Please refer to Figures 1 to 6 The utility model provides a strip material continuous feeding device of coating machine, which comprises a feeding line 1, a truss 2, an alignment module 3 and a push rod module 4, the feeding line 1 is used for conveying strip material, the truss 2 is arranged on the upper part of the feeding line 1, the alignment module 3 and the push rod module 4 are installed below the truss 2, above the feeding line 1, the alignment module 3 is used for aligning the strip material on the feeding line 1, and the push rod module is used for sequentially pushing the strip material on the feeding line into the next work section.
[0027] Please refer to Figure 2 The feeding line 1 specifically comprises a rack 1a, a group of parallel main shafts 1b and auxiliary shafts 1c are arranged on the rack 1a, the main shafts 1b and the auxiliary shafts 1c are chain transmission, a jig 1e for placing strip material is arranged on the transmission chain 1d, and a first motor 1f for driving the main shaft 1b to rotate is further arranged on the side of the rack 1a.
[0028] Please refer to Figures 3 to 6The alignment module 3 includes a set of symmetrically arranged guide plates, including a fixed guide plate 3a and a movable guide plate 3b, the fixed guide plate 3a is arranged at one end of the truss 2, and the movable guide plate 3b is fixed on the sliding table of the first linear module 3c, the first linear module 3c is driven by the second motor 3d, and the direction of the first linear module 3c is parallel to the length direction of the jig 1e, wherein the first linear module 3c is a prior art, which is an integrated module for realizing precise movement of the sliding table in the linear direction by means of a lead screw or a synchronous belt, mainly including a sliding table, a module body and a connection end at the end which can be connected to a motor, which will not be limited here, and in specific use, because the lengths of different batches of strips are different, it is necessary to first measure the length of the strips of the batch, and then drive the sliding table of the first linear module 3c by the second motor 3d to drive the movable guide plate 3b to move, so that the distance between the fixed guide plate 3a and the movable guide plate 3b is the same as the length of the strips of the batch, so that during manual feeding, the strips are placed in the jig 1e, the two ends of the strips are in contact with the fixed guide plate 3a and the movable guide plate 3b respectively, and after feeding is completed, the strips are automatically aligned.
[0029] Please continue to refer to Figures 3 to 6 The push rod module 4 includes a second linear module 4a and a third motor 4b, and the second linear module 4a and the third motor 4b are both mounted on the truss 2. The second linear module 4a is provided with a fixed block 4c, a spring 4d, a movable block 4e and a jam screw 4f on the sliding table. The fixed block 4c is fixed on the sliding table of the second linear module 4a, the fixed block 4c is connected with the movable block 4e through the jam screw 4f, and the spring 4d is sleeved on the jam screw 4f.

In specific application, when the feeding line 1 transports a strip to the lower side of the push rod module 4, the sliding table of the second linear module drives the movable block 4e to push the strip to slide along the length direction of the jig 1e for feeding. When the strip enters the coating equipment, the traction device in the coating equipment drives the strip to pass through the coating equipment. During the process, the sliding table of the second linear module retreats to the initial position. When the end of the strip leaves the jig 1e, the feeding line transports the next strip to the feeding position. At this time, the sliding table of the second linear module pushes the next strip to transport out along the length direction of the jig again. At this time, it is required that the sliding table of the second linear module first accelerates and then decelerates until the same speed as the previous strip, and the spring 4d is arranged to absorb the deformation amount generated by the collision when the two strips are in contact. On the one hand, it prevents the strip from being damaged, and on the other hand, it can also ensure that the speed of the next strip does not change during the coating process of the previous strip. When the next strip enters the coating equipment, the above feeding operation is repeated.
[0030] Specifically, the first linear module 3c is provided with a connecting plate 5, and the second linear module 4a is fixed on the connecting plate 5 and synchronously moves with the movable guide plate 3b. Through the above arrangement, the movable block 4e on the slide table of the second linear module 4a can correspond to one end of the strip placed on the feeding line 1. Thus, the control is more accurate and convenient during feeding and back-off.
[0031] Please refer to Figure 5 The truss 2 is further provided with a first linear guide rail 6 and a second linear guide rail 7. The slide table of the first linear guide rail 6 is fixedly connected with the movable guide plate 3b, and the second linear guide rail 7 is fixedly connected with the main body of the second linear module 4a. The linear guide rails can make the accuracy of reciprocating motion higher, prevent misalignment, and ensure the accuracy of feeding.
