Description

Technical Field

[0001] The utility model relates to the technical field of three-dimensional bag-making machines, in particular to a feeding device for a non-woven fabric three-dimensional bag-making machine. Background Art

[0002] A non-woven fabric three-dimensional bag-making machine is a device specifically used for producing non-woven fabric three-dimensional bags. It adopts advanced technology and can efficiently and accurately process non-woven fabric materials into three-dimensional bags of various specifications. The non-woven fabric three-dimensional bag-making machine is widely used in the fields of shopping bags, gift bags, packaging bags, etc. It has made contributions to environmental protection because the non-woven fabric material is degradable and reusable.

[0003] The feeding device of the non-woven fabric three-dimensional bag-making machine is an important part of the non-woven fabric three-dimensional bag-making machine, mainly responsible for accurately and stably conveying the non-woven fabric material to each processing station of the bag-making machine. It usually includes a feeding shaft and a tension control device. The feeding shaft is used to install the rolled non-woven fabric material, and the tension control device is used to adjust the tension of the non-woven fabric during transportation to ensure that the material is flat, not loose and not overly tightened. Subsequently, the driving roller is driven by a motor to drive the non-woven fabric material to be conveyed forward.

[0004] In daily work, it is found that when the existing feeding device of the non-woven fabric three-dimensional bag-making machine is in use, it can only place a set of rolled non-woven fabric materials. When this set of non-woven fabric materials is used up, it is necessary to stop the machine for material replacement operation, remove the used materials, and then place the new rolled non-woven fabric materials and perform the feeding operation. This results in time-consuming and laborious overall replacement, too long downtime, thus affecting the overall production efficiency, and further leading to the problems of inconvenient loading and unloading operations of the existing feeding device of the non-woven fabric three-dimensional bag-making machine and affecting the production efficiency.

A support assembly 52 is arranged on the surface of the machine body 1.

[0024] In this implementation manner: the square blocks 58 on the surface of the feeding rod 3 can be inserted into the grooves on the surface of the rotating frame 51, so as to realize the placement of two groups of feeding rods 3 at one time. The switching motor 53 is used for switching feeding, and the connecting assembly 57 is used for limiting. The rotating assembly 55 can drive the feeding rod 3 to rotate, so as to cooperate with the equipment for feeding operation.

[0025] Specifically, the connecting assembly 57 includes two threaded sleeves 571. The two threaded sleeves 571 are fixedly connected to the surface of the rotating frame 51. A screw 572 is threadedly connected to the inner wall of the threaded sleeve 571. The screw 572 penetrates through the inner wall of the rotating frame 51. A round hole 573 is formed on the surface of the square block 58. The screw 572 is inserted into the inner wall of the round hole 573.

[0026] In this implementation manner: after the square blocks 58 on the surface of the feeding rod 3 are inserted into the grooves on the surface of the rotating frame 51, the screw 572 can be rotated in the threaded sleeve 571 to make the screw 572 inserted into the round hole 573 on the surface of the square block 58, so as to realize the function of positioning connection.

[0027] Specifically, four rollers 54 are rotatably connected to the inner wall of the square block 58. The four rollers 54 are respectively arranged in pairs on both sides of the square block 58. After the square block 58 is inserted into the groove on the surface of the rotating frame 51, the rollers 54 can slide to reduce the friction effect.

When the non-woven fabric in one of the unwinding rods 3 is used up, the switching motor 53 is turned on, and the switching motor 53 drives the rotating frame to rotate to switch to another set of placement rods for feeding. At this time, the unwinding rod 3 with the used-up non-woven fabric can be removed, and a new unwinding rod 3 with non-woven fabric wound around it can be placed. Subsequently, the air cylinder 521 is turned on, and the air cylinder 521 drives the support frame 522 to move so that the support frame 522 moves below the rotating frame 51 to support and lift the rotating frame 51.
