Description

Technical Field

[0001] The utility model relates to the technical field of paper products, and more specifically, to a composite paper tube. Background Art

[0002] Paper tubes used in the textile field are mostly used to wind chemical fibers. In order to prevent the last section of chemical fibers from passing directly through the yarn guide frame, workers usually replace the new chemical fiber yarn tube in advance. In this way, the replaced chemical fiber yarn tube will have chemical fibers wrapped around the paper tube.

[0003] This part of residual chemical fiber can be recycled, so it needs to be cut off and recycled with a cutter. Since the outer wall of the traditional paper tube is flat and smooth, after being cut with a cutter, there will be cut marks and burrs on the surface, which makes the paper tube unable to be reused and the overall effect is not good. Based on this, the utility model proposes a composite paper tube. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies in the above-mentioned prior art and to provide a composite paper tube which is reusable and environmentally friendly.

[0005] In order to solve the above technical problems, the purpose of the utility model is achieved as follows: the utility model involves a composite paper tube, including a circular tube-shaped paper tube body, and a plurality of pasting grooves extending along the axial direction are opened on the outer tube wall of the paper tube body, and a cutting groove is opened at the bottom of each pasting groove, and a pasting strip is arranged in the pasting groove, and the pasting strip has a smooth surface and a sticky surface, and the sticky surface is connected to the bottom of the pasting groove.

[0006] The utility model is further configured as follows: the adhesive strip is provided with a row of tear holes arranged at intervals along the axial direction of the paper tube body; the tear holes are aligned with the cutting grooves.

[0007] The utility model is further configured that: the tear hole extends along the length direction of the adhesive strip.

[0008] The utility model is further configured such that the interval angles between two adjacent pasting grooves are equal.

[0009] The utility model is further configured as follows: the number of the pasting grooves is three or four.

[0010] The utility model is further configured as follows: the cross-section shape of the cutting groove is triangular.

[0011] In summary, the utility model has the following beneficial effects: the composite paper tube involved in the utility model, through the setting of the cutting groove, makes the cutting mark remain in the groove without protruding from the tube wall, and by replacing the adhesive strip in the adhesive groove, the paper tube can achieve the secondary utilization function, which is green and environmentally friendly, has complete overall functions and strong practicality.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the utility model.

[0015] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0016] Example 1

[0017] See also Figure 1 As shown, a composite paper tube involved in this embodiment includes a circular tube-shaped paper tube body 1, and a plurality of pasting grooves 2 extending along the axial direction are opened on the outer tube wall of the paper tube body 1, and a cutting groove 3 is opened at the bottom of each pasting groove 2, and a pasting strip 4 is arranged in the pasting groove 2, and the pasting strip 4 has a smooth surface 41 and a sticky surface 42, and the sticky surface 42 is connected to the bottom of the pasting groove 2.

[0018] Furthermore, the interval angles between two adjacent pasting grooves are equal.

[0019] Furthermore, the number of the pasting slots 2 is three or four.

[0020] Furthermore, the cross-section of the cutting groove 3 is in a triangular shape.

[0021] In this embodiment, the chemical fibers remaining on the paper tube body 1 can be cut off by using a cutter along the length extension direction of the cutting groove 3 to achieve the function of recycling the residual chemical fibers. After completing this action, the adhesive strip 4 covering the cutting groove 3 will be damaged and can be replaced to achieve the function of reusing the paper tube.
