Description

Technical Field

[0001] The utility model relates to the technical field of wet wipes processing, in particular to a buffer-type roll-feeding device for wet wipes processing. Background Art

[0002] In the wet wipes processing industry, the roll feeder is one of the key equipment to ensure the continuity and quality stability of wet wipes production. Traditional wet wipes processing buffer roll feeders mostly use a miniaturized counterweight structure. This design performs well in single roll fabric tension delivery and can meet general production needs. However, with the continuous development of the wet wipes market and the diversification of consumer demand, higher requirements are placed on wet wipes processing equipment.

[0003] Specifically, in order to improve production efficiency and reduce costs in modern wet wipes processing, it is often necessary to implement a production mode in which two small rolls of cloth are fed simultaneously on one shaft. This production mode requires the roll feeding device to be able to handle two rolls of cloth at the same time and maintain similar tension to ensure the quality and appearance of the wet wipes. However, the existing miniaturized counterweight structure roll feeding device is unable to cope with this production mode.

[0004] The design of the miniaturized counterweight structure limits its ability to handle multiple rolls of fabric. Due to the space and weight limitations of the counterweight structure itself, it is impossible to accommodate and balance the tension of two rolls of fabric at the same time. This results in a large difference in the tension of the two rolls of fabric during the actual production process, affecting the flatness and aesthetics of the wet wipes.

[0005] Therefore, a buffer-type roll-feeding device for wet wipes processing is needed to overcome the above-mentioned problems. Utility Model Content

[0006] In order to solve the above problems, the embodiment of the utility model provides a buffer-type roll-feeding device for processing wet wipes, which achieves the purpose of solving the problems raised in the background technology.

[0007] In order to achieve the above-mentioned purpose, the embodiment of the utility model specifically adopts the following technical scheme: a wet wipes processing buffer type roll feeding device, comprising a fixed frame, a tensioning frame slidably arranged below the fixed frame;

[0008] The fixed frame and the tensioning frame are both provided with roller shaft assemblies;

[0009] The roller assembly comprises a connecting shaft and two rotating rollers rotatably arranged on the connecting shaft.

[0010] As a further improvement of the above technical solution:

[0011] The tensioning frame is slidably arranged below the fixing frame through a sliding assembly.

[0012] The sliding assembly comprises a guide rail and a slider slidably arranged on the guide rail, and the slider is fixedly connected to one side of the tensioning frame.

[0013] The fixing frame is fixedly connected with a cylinder, and the piston rod of the cylinder is fixedly connected with the tensioning frame.

[0014] The tensioning frame is provided with a connecting rod for installing a counterweight.

[0015] The beneficial effects of the embodiments of the utility model are:

[0016] In actual use, the cloth is wound around the roller assembly on the fixed frame and the roller assembly on the tensioning frame. After the tensioning frame is released, the cloth is tensioned under the action of its own gravity. At the same time, since two independent rotating rollers are arranged on the roller assembly, the two rolls of cloth are respectively wound on different rotating rollers, so that the two rolls of cloth do not affect each other when passing on the roller assembly, thereby ensuring the purpose of tensioning the two rolls of cloth at the same time through the tensioning frame, and tensioning the two rolls of cloth through the same tensioning frame, so that the tensioning force of the two rolls of cloth is the same.

[0020] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0021] See also Figure 1 to Figure 2 , the embodiment of the utility model discloses a wet wipes processing buffer type roll feeding device, comprising a fixing frame 1, a tensioning frame 2 slidably arranged below the fixing frame 1;

[0022] The fixed frame 1 and the tensioning frame 2 are both provided with a roller 1 shaft assembly 3;

[0023] The roller assembly 3 includes a connecting shaft 31 and two rotating rollers 32 rotatably arranged on the connecting shaft 31;

[0024] In actual use, the cloth is wound around the roller assembly 3 on the fixed frame 1 and the roller assembly 3 on the tensioning frame 2. After the tensioning frame 2 is released, the cloth is tensioned under the action of its own gravity. At the same time, since two independent rotating rollers 32 are provided on the roller assembly 3, the two rolls of cloth are respectively wound around different rotating rollers 32, so that the two rolls of cloth do not affect each other when passing through the roller assembly 3, thereby ensuring the purpose of tensioning the two rolls of cloth at the same time through the tensioning frame 2, and tensioning the two rolls of cloth through the same tensioning frame 2, so that the tensioning force of the two rolls of cloth is the same.

[0025] As a further illustration of this application:

[0026] The tensioning frame 2 is slidably arranged below the fixing frame 1 through the sliding assembly 4 , and the normal sliding of the tensioning frame 2 is ensured by the sliding assembly 4 .

[0027] As a further illustration of this application:

[0028] The sliding assembly 4 includes a guide rail 41 and a slider 42 slidably disposed on the guide rail 41 . The slider 42 is fixedly connected to one side of the tensioning frame 2 . In actual use, the slider 42 slides on the guide rail 41 to ensure that the tensioning frame 2 moves up and down normally.

[0029] As a further illustration of this application:

[0030] The fixed frame 1 is fixedly connected with a cylinder 5, and the piston rod of the cylinder 5 is fixedly connected with the tensioning frame 2. When winding the cloth, the tensioning frame 2 is driven upward by the cylinder 5, thereby reducing the distance between the fixed frame 1 and the tensioning frame 2, which is convenient for winding the cloth; after the cloth is loaded, the feeding and rolling movement begins, and the cylinder 5 is gradually released until it does not provide any force at all, so that the tensioning frame 2 falls due to its own gravity, and interacts with the pulling force generated during the cloth conveying process, so as to achieve the purpose of non-powered adaptive control of the feeding and rolling tension;

[0031] In actual use, the cylinder 5 can also always provide pulling force or pushing force for the tensioning frame 2, thereby increasing or reducing the pressure of the tensioning frame 2 on the cloth, so as to meet the different requirements of cloth of different materials for tensioning force.

[0032] As a further illustration of this application:

[0033] The tensioning frame 2 is provided with a connecting rod 6 for mounting a counterweight. The number of the counterweight can be increased or decreased according to factors such as the thickness and material of the fabric, thereby changing the tension provided by the tensioning frame 2 to the fabric.
