Technical Field

[0001] The present application relates to the field of paper handles, and in particular to a paper tape guiding and feeding assembly. Background Art

[0002] At present, with the development of society, the promotion of paper handles can convey the concept of environmental protection to consumers, allowing consumers to pay more attention to the environmental attributes of products when shopping. When consumers see products with paper handles, they will be more inclined to choose these environmentally friendly products, thereby promoting companies to increase their investment in environmentally friendly packaging. This change in consumer concepts will have a positive impact on the entire market, prompting more companies to adopt environmentally friendly materials and production processes, and forming a good atmosphere for green consumption.

[0003] The existing raw materials for handles are usually paper tapes. During the production process of paper handles, in order to improve production efficiency, multiple lines are usually operated simultaneously, and several paper tapes are usually fed into the multiple lines at the same time to improve production efficiency.

[0004] The above-mentioned existing technical solutions have the following defects: the paper tape has a path deviation during transportation, which causes confusion in material loading and leads to a low qualified rate of finished products. Utility Model Content

[0005] In order to improve the qualified rate of finished products of paper handles, the present application provides a paper tape guiding feeding component.

[0006] The above technical objectives of this application are achieved through the following technical solutions:

[0008] By adopting the above solution, because the first dividing strip is provided, the bottom plate is divided into several channels, which facilitates the simultaneous delivery of several paper tapes to the machine body. Because the second dividing strip is provided, a conveying groove is formed between the second dividing strip and the first dividing strip. The conveying groove can limit the paper tape to prevent the paper tape from being offset during the process of being delivered to the line body, thereby achieving the effect of improving the qualified rate of finished paper handle production products.

[0009] Furthermore, a paper tape guiding and loading assembly also includes a conveying structure connected to the machine body, the conveying structure includes a guiding assembly, a conveying plate and a driving assembly, one end of the conveying plate is fixedly connected to the machine body, the bottom plate is located on the side of the conveying plate away from the line body, and the bottom plate is fixedly connected to the conveying plate; the guiding assembly is located on the side of the bottom plate away from the conveying plate, the guiding assembly is connected to the line body, and the guiding assembly is used to guide the paper tape through the bottom plate into the conveying plate; the driving assembly is located above the conveying plate, the driving assembly is connected to the line body, and the driving assembly is used to convey the paper tape on the conveying plate to the machine body.

[0010] By adopting the above scheme, several paper tapes are placed into each conveying groove in turn through the guiding assembly, so that the front end of each paper tape is located on the conveying plate, and then the driving assembly is started, the driving assembly is in contact with each paper tape, and the driving assembly itself rotates, pushing all the paper tapes to move along the conveying plate toward the machine body, thereby achieving the effect of improving the production efficiency of paper handles.

[0011] Furthermore, the side walls of each of the first and second dividing bars close to the guide assembly (11) are arranged in an arc shape.

[0012] By adopting the above solution, the arc-shaped arrangement facilitates guiding the paper tape into the separation groove.

[0013] Furthermore, the driving assembly includes a support frame, which is U-shaped as a whole and has an opening facing the conveying plate, and both ends of the support frame are fixedly connected to the line body; it also includes a pushing member and a first rack, the pushing member is fixedly connected to the top wall of the conveying plate, and the first rack is fixedly connected to the output end of the pushing member; a driving wheel is provided on the side of the first rack away from the conveying plate, the driving wheel is meshed with the rack, and the first rack is telescopic to drive the driving wheel to rotate; a linkage rod is inserted into the wheel core of the driving wheel, and the two sides of the linkage rod are respectively fixedly connected to the first wheel and the second wheel, and both ends of the linkage rod are rotatably connected to the side walls of the support frame; the top wall of the support frame is fixedly connected to a telescopic assembly meshed with the first wheel and the second wheel corresponding to the first wheel and the second wheel, and the first wheel and the second wheel are used to drive the telescopic assembly to rise and fall; a conveying wheel is provided on the side of the telescopic assembly close to the conveying plate, and the two ends of the conveying wheel are respectively rotatably connected to the two telescopic assemblies, driving the conveying wheel to rotate and drive the paper tape to move along the conveying plate.

[0014] By adopting the above scheme, the driving member pushes the first rack to move, and the first rack drives the driving wheel to rotate. Because the first wheel and the second wheel are connected to the driving wheel through a linkage rod, the rotation of the first rack can drive the first wheel and the second wheel to rotate synchronously; the first wheel and the second wheel respectively drive the two telescopic components to rise and fall, and the telescopic components drive the conveying wheel to rise and fall, thereby adjusting the position relationship between the conveying wheel and the conveying plate; because the linkage rod is provided, the rotation speed of the first wheel and the second wheel is consistent, and the extension amount of the two telescopic rods is consistent, further making the two sides of the conveying wheel in a balanced state; when the position of the conveying wheel is adjusted to abut against the paper tape on the conveying plate, the conveying wheel is driven to rotate, which can drive the paper tape to move along the conveying plate in a direction close to the machine body.

[0015] Furthermore, each of the telescopic components includes a sleeve and a second rack, the sleeve is fixedly connected to the top wall of the support frame, the second rack is arranged inside the sleeve, and the second rack is slidably connected to the sleeve; a connecting groove is opened on the side wall of the sleeve, and the first wheel or the second wheel is engaged with its corresponding second rack through the connecting groove.
