Description

Technical Field

[0001] The utility model relates to the technical field of paper tube processing, in particular to a paper tube continuous precision cutting device. Background Art

[0002] Paper tube, also known as paper tube or paper roll, is a cylindrical material made of paper or cardboard. It is widely used in various industries such as textile, chemical fiber, printing and dyeing, papermaking, agricultural film, pharmaceuticals, food packaging, plastic film, electronics, steel, metallurgy, etc.

[0003] Paper tubes are widely used in many industries, such as textiles, papermaking, cigarettes, etc. With the development of science and technology, the processing requirements for paper tubes are getting higher and higher, especially the cutting accuracy of paper tubes. Traditional paper tube cutting equipment is mostly single cutting, with low efficiency and difficulty in ensuring accuracy. Therefore, there is an urgent need for a paper tube processing device that can achieve continuous precision cutting. Utility Model Content

[0004] The purpose of the utility model is to provide a paper tube continuous precision cutting device to solve the problems raised in the above background technology.

The paper tubes can be limited and separated by the limit frames, and the height of the gantry is adjustable. The staff can adjust the gantry to the specified height according to the diameter and thickness of the paper tubes. The paper tubes are clamped and limited by the cooperation of the limit rollers and the rotating rollers set at the bottom of the gantry to ensure stable transmission of the paper tubes. At this time, the electric telescopic frame is started to push the moving cutter, and the feeding of the moving cutter can cooperate with the static cutter to cut the paper tube. The operation of various electrical equipment inside the device depends on the external PLC control unit. The control unit can also adjust the cutting speed and accuracy according to actual needs. The static cutter and the moving cutter are both made of carbide materials, which improves the cutting accuracy and extends the service life. The device can continuously cut paper tubes through the coordinated use of various components, and the paper tubes can be limited by the cooperation of the limit rollers and the rotating rollers, which improves the cutting accuracy of the device for paper tubes.

[0007] Preferably, a knife seat is provided on one side of the top of the base, and a static cutting knife is fixedly mounted on one side of the top of the knife seat.

[0008] The knife holder can provide an installation position for the static cutter. The static cutter can be used in conjunction with the dynamic cutter to generate shear force on the paper tube through relative feeding and cut the paper tube.

[0009] Preferably, a movable cutter is installed at the output end of the electric telescopic frame, and the movable cutter is engaged with the static cutter.

[0010] The electric telescopic frame can push the moving cutter when it is powered on, and the feeding movement of the moving cutter can cooperate with the static cutter to generate shear force on the paper tube.

[0013] Preferably, the limiting roller and the rotating roller are both wrapped with a rubber layer.

[0014] The rubber layer wrapped around the limiting roller and the rotating roller can increase the friction when they come into contact with the paper tube, ensuring that the device can stably limit the paper tube and reduce damage to the paper tube during the clamping process.

[0015] In summary, this application includes the following beneficial technical effects:

[0016] The static cutter and the dynamic cutter in the utility model are both made of hard alloy material, which improves the cutting accuracy and prolongs the service life.

DETAILED DESCRIPTION

[0022] The following specific embodiments are provided to help the reader obtain a comprehensive understanding of the methods, devices and / or systems described herein. However, after understanding the disclosure of the present application, various changes, modifications and equivalents of the methods, devices and / or systems described herein will be apparent. For example, the order of operations described herein is merely an example, and is not limited to the order set forth herein, but in addition to the operations that must occur in a particular order, changes that will be apparent after understanding the disclosure of the present application may be made. In addition, in order to improve clarity and brevity, descriptions of features known in the art may be omitted.

[0023] The features described herein may be implemented in different forms and should not be interpreted as being limited to the examples described herein. Rather, the examples described herein have been provided only to illustrate some of the many possible ways of implementing the methods, devices and / or systems described herein that will be apparent after understanding the disclosure of the present application.

[0024] Throughout the specification, when an element (such as a layer, a region, or a substrate) is described as being “on”, “connected to”, “bound to”, “over”, or “covering” another element, it may be directly “on”, “connected to”, “bound to”, “over”, or “covering” another element, or one or more other elements may be present between them. In contrast, when an element is described as being “directly on”, “directly connected to”, “directly bound to”, “directly over”, or “directly covering” another element, there may be no other elements present between them.

[0025] As used herein, the term "and / or" includes any one of the associated listed items and any combination of any two or more items.

[0026] Although terms such as "first," "second," and "third" may be used herein to describe various members, components, regions, layers, or portions, these members, components, regions, layers, or portions are not limited by these terms. Rather, these terms are only used to distinguish one member, component, region, layer, or portion from another member, component, region, layer, or portion. Therefore, without departing from the teachings of the examples described herein, the first member, component, region, layer, or portion referred to may also be referred to as the second member, component, region, layer, or portion.

[0027] For ease of description, spatial relative terms such as "above", "upper", "below", and "lower" may be used herein to describe the relationship of one element to another element as shown in the drawings. Such spatial relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the drawings. For example, if the device in the drawings is turned over, an element described as being "above" or "upper" relative to another element would then be located "below" or "lower" relative to the other element.

[0028] Therefore, the term "above" includes both "above" and "below" orientations depending on the spatial orientation of the device. The device may be otherwise oriented (e.g., rotated 90 degrees or at other orientations), and the spatially relative terms used herein will be interpreted accordingly.

[0029] The terms used herein are only used to describe various examples and are not used to limit the present disclosure. Unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. The terms "include", "comprise" and "have" list the stated features, quantities, operations, components, elements and / or their combinations that exist, but do not exclude the existence or addition of one or more other features, quantities, operations, components, elements and / or their combinations.

[0030] Variations in the shapes shown in the drawings may occur due to manufacturing techniques and / or tolerances. Therefore, the examples described herein are not limited to the specific shapes shown in the drawings but include variations in shapes that occur during manufacturing.
