Description

Technical Field

[0001] The utility model relates to the technical field of large circular knitting machines, in particular to unloading equipment of an automatic cloth rolling and slitting machine. Background Art

[0002] In the textile operation process, after the knitting machine finishes weaving, the cloth must be pulled to a cloth winding machine, which will use the cloth winding machine to wind the cloth onto a cloth roller. After the cloth is rolled, the cloth roller is taken out through cutting and transported to the storage area.

[0003] At present, when taking the rolled fabric on the large circular machine, some large circular machines use automatic unloading to unload the cloth roller and fabric on the large circular machine, and the discharged cloth roller and fabric lack a cloth dropping structure, so it is necessary to manually take the guided fabric. This process requires workers to enter the bottom of the large circular machine to take the material. It has a low degree of automation and low work efficiency, which increases the workload of workers and increases safety hazards. On the other hand, in actual use, when a cloth roller completes the target work, the AGV trolley will come over to pull away the cloth roller that has completed the cloth rolling. The transportation process takes a certain amount of time, and it takes about 4-20 hours to complete a cloth rolling action. The AGV trolley can only transport one cloth roller at a time, which greatly reduces the transportation efficiency of the AGV trolley.

[0004] In view of this, the inventor of this case conducted in-depth research on the above-mentioned issues, which resulted in this case. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Reference Figures 1 to 5 :

[0029] A discharging device of an automatic cloth rolling and slitting machine is used for receiving a cloth rolling roller 10 of cloth. For the convenience of description, the falling direction of the cloth rolling roller 10 is defined as forward, and the opposite direction is defined as backward.

[0030] The present application includes a material guide device arranged at the front end of a cloth rolling machine (not shown in the figure), the material guide device includes a first material guide frame 1, a second material guide frame 2 arranged at the front end of the first material guide frame 1, and a moving mechanism arranged between the first material guide frame 1 and the second material guide frame 2 and moving the cloth rolling roller 10 that falls on the first material guide frame 1 to the second material guide frame 2. A buffer device is erected at the front end of the first material guide frame 1 to prevent the cloth rolling roller 10 from rolling out of the first material guide frame 1, and the height of the buffer device is greater than the height of the front end of the first material guide frame 1. Specifically, the buffer device is a limiting roller 11 arranged at the end of the first material guide frame 1, and there is a height difference between the limiting roller 11 and the front end of the first material guide frame 1. It is worth noting that the buffer device in this embodiment can adopt the second buffer device in the Chinese utility model patent CN221607271U, the purpose of which is to reduce the noise generated by the impact force of the cloth rolling roller 10 falling to the first material guide frame 1 and moving and hitting the limiting roller 11, and to reduce the deformation of the cloth rolling roller 10 and the limiting roller 11.
