Fixing mechanism 4 comprises first connecting piece and second connecting piece for clamping and rotating zipper belt roller 41, the second connecting piece or the first connecting piece is connected to fixing mechanism 4 through a telescopic support, and the first connecting piece and the second connecting piece both have a rotating shaft, one rotating shaft is connected with a motor for rotating zipper belt roller 41 to release the belt, for guiding the zipper belt released by fixing mechanism 4 to the ironing machine, the difference is that the buffer structure 1 is arranged at the discharge end of guide assembly 3 of the present belt feeder, the zipper belt released by fixing mechanism 4 is guided to the discharge end by guide assembly 3, that is, connected to belt outlet pipe 12, the zipper belt is guided into first opening 111 by belt outlet pipe 12, so that part of the zipper belt is stored in storage belt cavity 11, and the zipper belt is taken out from second opening 112 of storage belt cavity 11 to connect the ironing machine. It should be noted that the ironing machine has guide assembly 3 for feeding, that is, zipper belt feeding mechanism, buffer structure 1 further comprises a mounting plate and is mounted on base 2 through the mounting plate, and the belt feeder of the structure is as shown in Figure 1The two symmetrically arranged guiding assemblies 3 can simultaneously supply two zipper tapes, and the two symmetrically arranged fixed mechanisms 4 can simultaneously supply two zipper tapes, so the buffer structure 1 is also arranged as two to match the two fixed mechanisms 4.

[0025] The utility model discloses a kind of buffer structures of tape supply machine, by the buffer structure 1 being set in the discharge end of guiding assembly 3, tape supply machine first places tape and utilizes its storage tape cavity 11 to temporarily store the zipper tape placed, to supply to ironing machine and other equipment, such as when the zipper tape roller 41 on tape supply machine is placed, new zipper tape roller 41 can be directly replaced, during this period, the zipper tape in storage tape cavity 11 continuously supplies ironing machine, need not pause, effectively improve production efficiency, simultaneously reduce the influence of the sudden pause or supply of zipper tape to the temperature in ironing machine, prevent ironing machine temperature from appearing too high or too low and affect zipper tape quality.Moreover, the tape supply machine also has the function of placing tape, and can directly place tape.

[0026] In the embodiment, the tape outlet pipe 12 is arranged below the discharge end of the guiding assembly 3, and the zipper tape at the discharge end of the guiding assembly 3 is guided to the first opening 111 below the tape outlet pipe 12. The tape outlet wheel set 13 is arranged between the guiding assembly 3 and the tape outlet pipe 12, and the tape outlet wheel set 13 includes two abutting rollers, one of which is connected with a motor. The tape outlet wheel set 13 is used for guiding the zipper tape from the guiding assembly 3 to the tape outlet pipe 12. The zipper tape mainly relies on its own weight and naturally falls into the tape outlet pipe 12. The falling speed is too slow. The zipper tape first passes through the tape outlet wheel set 13. The roller is driven by the motor. The zipper tape can be pulled from the guiding assembly 3 to the tape outlet pipe 12 by using the power provided by the tape outlet wheel set 13, so as to improve the speed of the zipper tape entering the storage tape cavity 11.

[0027] In the embodiment, the buffer structure 1 comprises a swinging device 121, which comprises a motor and an eccentric swing arm assembly. The eccentric swing arm assembly comprises a rotating clamp, a connecting rod, a tape outlet pipe fixing block and a swing shaft. One end of the rotating clamp is connected to the rotating shaft of the motor, and the other end is connected to one end of the tape outlet pipe fixing block through the connecting rod. The other end of the tape outlet pipe fixing block is connected to the swing shaft, which is rotatably installed on the mounting plate through a bearing, ensuring that the swing shaft can rotate. It should be noted that the swinging device is prior art and is not limited to the above structure. What needs to be known is that the output end of the swinging device 121 is connected to the upper part of the tape outlet pipe 12, so that the tape outlet pipe 12 swings around the output end. The tape outlet pipe 12 is through at both ends. The output end of the swinging device 121 is connected to the upper part of the tape outlet pipe 12, so that the inlet at the upper end of the tape outlet pipe 12 has a relatively small swing range. It is mainly used for swinging the outlet at the lower end of the tape outlet pipe 12, so that the zipper tape is output to the tape storage cavity 11 through the tape outlet pipe 12, achieving the effect of preventing the zipper tape from bunching. At the same time, it can also cooperate with the tape outlet wheel set 13 to realize the rapid winding of the zipper tape of the guide assembly 3 into the tape storage cavity 11. It should be noted that the swing range of the tape outlet pipe 12 should be smaller than the length of the first opening 111 to prevent the zipper tape from falling out of the tape storage cavity 11.

[0028] In the embodiment, a sensor 113 for detecting the amount of zipper tape in the tape storage cavity 11 is arranged outside the tape storage cavity 11. The sensor 113 comprises a high-level sensor 113 and a low-level sensor 113. The high-level sensor 113 is close to the first opening 111, and the low-level sensor 113 is arranged below the high-level sensor 113. The high-level sensor 113 and the low-level sensor 113 can be, for example, proximity sensors, photoelectric sensors, etc. They are mainly used to control the amount of zipper tape in the tape storage cavity 11. When the zipper tape is below the low-level sensor 113, i.e., there is not much zipper tape in the tape storage cavity 11, the tape feeder needs to be started to continue feeding the tape. When the zipper tape reaches the high-level sensor 113, i.e., the amount of zipper tape in the tape storage cavity 11 is sufficient, the tape feeder can be paused at this time. It extends to the ironing machine part. At this time, the ironing machine continues to introduce the zipper tape in the tape storage cavity 11. If the zipper tape is below the detection range of the low-level sensor 113, the tape feeder will be started to continue feeding the tape into the tape storage cavity 11. Generally, since the tape feeder continuously feeds the tape and the ironing machine continuously introduces the zipper tape, the amount of zipper tape in the tape storage cavity 11 will not change greatly.

[0029] In the embodiment, the fixing mechanism 4 comprises a tape shortage sensing switch 42, which is a proximity sensing switch or other sensor with the same function. It is convenient to monitor the tape feeding in real time. When the tape feeding of a zipper tape roller 41 is completed, the tape shortage sensing switch 42 detects the shortage of tape, and then the rotation of the fixing mechanism 4 is paused. At this time, the worker replaces the zipper tape roller 41.

[0030] In the embodiment, the bottom of the storage cavity 11 has a sector 110, and the second opening 112 is arranged upward on the sector 110. The first opening 111 and the second opening 112 are both arranged upward. The guide assembly 3 of the ironing machine and the tape supply machine are both arranged to be high. If the second opening 112 is arranged downward on the storage cavity 11, the smoothness of the zip fastener tape that is folded back to the high position of the guide assembly 3 of the ironing machine at the second opening 112 of the storage cavity 11 is poor. Therefore, the sector 110 is arranged. When the zip fastener tape enters the storage cavity 11, the zip fastener tape is pushed to the second opening 112 along the sector 110. Further, the buffer structure 1 comprises a tape throwing wheel 14. The tape throwing wheel 14 is arranged above the second opening 112. The tape throwing wheel is provided with a motor. The motor drives the tape throwing wheel to rotate in the opposite direction of the driving direction of the zip fastener tape. When the zip fastener tape is in a knot, the tape throwing wheel can separate the knot. The zip fastener tape at the second opening 112 is wound around the tape throwing wheel 14 and connected to the guide assembly 3 of the ironing machine through the tape throwing wheel 14. Preferably, the height of the tape throwing wheel 14 corresponds to the height of the guide assembly 3.

[0031] In summary, in the initial tape supply, the staff first arranges the zip fastener tape roller 41 on the fixing mechanism 4 and winds the zip fastener tape in the order of the guide assembly 3, the tape outlet wheel set 13, the tape outlet pipe 12 from one end of the zip fastener tape. As the tape is unwound, the zip fastener tape gradually enters the storage cavity 11 and finally slides out of the second opening 112 along the sector 110 in the storage cavity 11. The staff pulls out the end of the zip fastener tape from the second opening 112, so that the end of the zip fastener tape is exposed from the second opening 112, which facilitates the staff to quickly find the end and connect the ironing machine. The fixing mechanism 4 is started to continuously unwind the zip fastener tape from the zip fastener tape roller 41. After the zip fastener tape passes through the guide assembly 3, the zip fastener tape enters the tape outlet pipe 12. The tape outlet pipe 12 swings left and right under the action of the swinging device 121, so that the zip fastener tape that passes through the tape outlet pipe 12 enters the storage cavity 11 in a detour, preventing the zip fastener tape from knotting. When the amount of the zip fastener tape in the storage cavity 11 reaches a certain amount, the end of the zip fastener tape at the second opening 112 is connected to the ironing machine. At this time, the speed of the ironing machine is equivalent to the speed of the tape supply machine, that is, the tape supply machine unwinds the zip fastener tape while the ironing machine connects the zip fastener tape. Therefore, the amount of the zip fastener tape in the storage cavity 11 is relatively stable. When the zip fastener tape roller 41 is unwound and the lack of tape is detected by the lack of tape sensing switch 42, it indicates that the zip fastener tape roller 41 of the fixing mechanism 4 is unwound. The fixing mechanism 4 is temporarily stopped. After the staff replaces the new zip fastener tape roller 41, the fixing mechanism 4 is restarted to rotate. It should be noted that the ironing machine continuously introduces the zip fastener tape in the storage cavity 11 during the replacement of the zip fastener tape roller 41, and the ironing machine does not need to be temporarily stopped, so that the ironing machine does not affect the introduction of the zip fastener tape.

[0032] The above embodiment is a preferred embodiment of the present application. Any similar structure and equivalent changes made should be within the protection scope of the present application.
