Abstract

A paper separator provided with an adhesive tape cutting assembly includes a housing structure and an adhesive tape cutting assembly, where a housing has an open first end and an open second end, the first end and the second end are axially through and forms a cavity capable of accommodating a paper roll inside the housing; a cavity opening is formed in an outer wall of the housing and is axially formed from the first end to the second end; and the adhesive tape cutting assembly is fixedly mounted on the outer wall of the housing and is configured to be sleeved with an adhesive tape roll and cut an adhesive tape.

First claim

What is claimed is:

1. A paper separator provided with an adhesive tape cutting assembly, comprising: a housing structure and an adhesive tape cutting assembly, wherein
the housing structure comprises:
a housing which has an open first end and an open second end, the first end and the second end being axially through and forming a cavity capable of accommodating a paper roll inside the housing; and
a cavity opening which is formed in an outer wall of the housing, is axially formed from the first end to the second end, and is in communication with the accommodating cavity, to-be-cut paper of the paper roll in the accommodating cavity being selectively pulled out from the cavity opening, and paper separation being performed by means of a first side wall of the housing adjacent to the cavity opening; and
the adhesive tape cutting assembly is fixedly mounted on the outer wall of the housing and is configured to be sleeved with an adhesive tape roll and cut an adhesive tape;
the adhesive tape cutting assembly comprises a serrated knife and a protective assembly; the protective assembly comprises a protective member and a sliding member; the sliding member is mounted on a sliding groove and moves along the sliding groove to expose the serrated knife for cutting under an action of an external force;
the sliding member comprises a side wall extension, a bottom wall of the protective member is provided with a notch, the side wall extension abuts against an inner surface of the notch and sides in the notch; wherein the adhesive tape cutting assembly further comprises a mounting frame which is connected to the housing, the sliding groove is formed in the mounting frame, the sliding member is provided with a sliding rail, the sliding groove is matched with the sliding rail, and the sliding groove defines a movement range and direction of the sliding member; wherein the sliding rail comprises a protrusion, the protrusion abuts against a side wall, facing away from the serrated knife, of the mounting frame.

2. The paper separator provided with an adhesive tape cutting assembly according to claim 1 , wherein the adhesive tape cutting assembly further comprises:
an adhesive tape sleeving shaft which is connected to the outer wall of the housing, is selectively sleeved with the adhesive tape roll, and allows the adhesive tape roll to rotate stably so as to pull out the adhesive tape; and
a knife fixing member which is arranged on the same side as the adhesive tape sleeving shaft and connected to the outer wall of the housing, wherein the serrated knife is mounted on the knife fixing member and configured to be capable of cutting the adhesive tape pulled out from the adhesive tape roll.

3. The paper separator provided with an adhesive tape cutting assembly according to claim 2 , wherein the protective assembly is connected to the housing and arranged on a periphery of the knife fixing member, and is capable of hiding a cutting edge of the serrated knife when in a protective state.

4. The paper separator provided with an adhesive tape cutting assembly according to claim 2 , wherein a reserving member is arranged on one side of the knife fixing member facing the adhesive tape sleeving shaft and is configured to attach a reserved portion of the adhesive tape after cutting.

5. The paper separator provided with an adhesive tape cutting assembly according to claim 2 , wherein an end portion of an outer side of the adhesive tape sleeving shaft is provided with a convex edge extending outwards in a radial direction thereof, and the convex edge is configured to limit a lateral movement of the adhesive tape roll along a longitudinal axis of the adhesive tape sleeving shaft.

6. The paper separator provided with an adhesive tape cutting assembly according to claim 1 , wherein the protective assembly further comprises:
a spring, wherein when the external force is removed from the sliding member, the spring provides an elastic force for the sliding member such that the sliding member is pushed back to an initial position and the cutting edge of the serrated knife is hidden.

7. The paper separator provided with an adhesive tape cutting assembly according to claim 6 , wherein the protective member is fixedly connected to the housing, constitutes a housing portion of the protective assembly, and is configured to accommodate and mount the sliding member and provide a support for the spring.

8. The paper separator provided with an adhesive tape cutting assembly according to claim 1 , wherein an inner bottom wall of the housing is an inclined surface and is inclined in a direction of the cavity opening.

9. The paper separator provided with an adhesive tape cutting assembly according to claim 8 , wherein the inner bottom wall of the housing is provided with at least two protruding inclined strips, and an arrangement direction of the inclined strips is perpendicular to a forming axis direction of the cavity opening.

10. The paper separator provided with an adhesive tape cutting assembly according to claim 1 , wherein an outer bottom wall of the housing is a plane for supporting an integrated device.

11. The paper separator provided with an adhesive tape cutting assembly according to claim 1 , wherein an outer bottom wall of the housing is further provided with a non-slip pad.

12. The paper separator provided with an adhesive tape cutting assembly according to claim 1 , wherein an outer side wall of the housing is further provided with non-slip lines.
