Description

Technical Field

[0001] The utility model relates to a gear, in particular to a gear structure of a shredder. Background Art

[0002] A shredder is a mechanical device used to cut paper or other materials into small pieces or strips. In a shredder, multiple transmission mechanisms composed of gears or gear sets are provided to transmit the power of the motor to the blade, so that the blade rotates rapidly to cut paper or other materials.

[0003] However, in the current production of shredders, ordinary gears are usually directly selected. However, in actual use, the strength and rigidity requirements for some gears are not high, which causes the motor in the shredder to consume more power to drive the gear, resulting in an increased working load of the shredder and an increased production cost of the shredder. Summary of the Utility Model

[0004] In order to solve the problems in the related technologies, the present application provides a gear structure of a shredder, which solves the problems of increased working load and increased input cost of the shredder.

[0005] The technical solution is as follows:

[0006] A gear structure of a shredder includes a gear. The feature is that through a stretching process, a reinforcing member integrally formed is connected along the outer periphery of the central shaft hole of the gear blank of the gear, and the thickness of the reinforcing member is 2-10 mm.

[0007] Through the above technical solution, through the setting of the reinforcing member, by pressing the gear blank to make it extend into the reinforcing member, not only can the thickness of the gear be reduced, thereby reducing the working load on the shredder, but also the reinforcing member integrally formed with the gear after extension can increase the strength of the gear, ensure the normal use of the gear, and thus reduce the input cost.

[0008] Preferably, the inner wall surface of the reinforcing member and the inner wall of the central shaft hole of the gear are in a coincident state.

[0009] Preferably, the central shaft hole of the gear is arranged in a regular polygon shape.

[0010] Preferably, the reinforcing member is arranged in a circular ring or polygonal ring shape.

[0011] In summary, the beneficial effect of a gear structure of a shredder is that through the setting of the reinforcing member, by pressing the gear blank to make it extend into the reinforcing member, not only can the thickness of the gear be reduced, thereby reducing the working load on the shredder, but also the reinforcing member integrally formed with the gear after extension can increase the strength of the gear, ensure the normal use of the gear, and thus reduce the input cost.

[0012] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present utility model. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Here, the exemplary embodiments will be described in detail, and the examples are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present utility model. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present utility model as detailed in the appended claims.

[0018] Embodiment 1, as shown in the attached Figure 1 As shown, a shredder gear 1 structure includes a gear 1. By means of a stretching process, a blank of the gear 1 is extended along the outer periphery of the central shaft hole of the gear 1 to connect with an integrally formed reinforcing member 2. It is only necessary to use a machine that can process the gear 1 to reduce its thickness and connect the excess material into the reinforcing member 2. Here, the process of reducing the thickness of the gear 1 and stretching out the reinforcing member 2 by using the stretching process belongs to common knowledge and will not be elaborated here. The thickness of the reinforcing member 2 is 2 - 10 mm, that is, the stretching length value of the reinforcing member 2 is 2 - 10 mm; by pressing the material of the gear 1 to make it extend into the reinforcing member 2, not only can the thickness of the gear 1 be reduced, thereby reducing the working load on the shredder, but also the integrally formed reinforcing member 2 after extension can increase the strength of the gear 1, ensure the normal use of the gear 1, and thus reduce the input cost. The inner wall surface of the reinforcing member 2 coincides with the inner wall of the central shaft hole of the gear 1; the central shaft hole of the gear 1 is set in a regular polygon shape. In this embodiment, the shaft hole of the gear 1 is set in a regular hexagon shape, and the inner wall of the reinforcing member 2 is also set in a regular hexagon shape; the reinforcing member 2 is set in a circular ring or polygonal ring shape. In this embodiment, the outer edge of the reinforcing member 2 is set in a regular hexagon shape.

[0019] Embodiment 2, as shown in the attached Figure 2As shown, a structure of a shredder gear 1 includes a gear 1. By means of a stretching process, a blank of the gear 1 is extended along the outer periphery of the central shaft hole of the gear 1 to be connected with an integrally formed reinforcing member 2. It is only necessary to use a machine that can process the gear 1 to reduce its thickness and connect the redundant material into the reinforcing member 2. Here, the process of using the stretching process to reduce the thickness of the gear 1 and stretch out the reinforcing member 2 belongs to common knowledge and will not be elaborated here. The thickness of the reinforcing member 2 is 2 - 10 mm, that is, the stretching length value of the reinforcing member 2 is 2 - 10 mm. By pressing the blank of the gear 1 to make it extend into the reinforcing member 2, not only can the thickness of the gear 1 be reduced, thereby reducing the working load on the shredder, but also the integrally formed reinforcing member 2 after extension can increase the strength of the gear 1, ensuring the normal use of the gear 1, and thus reducing the input cost. The inner wall surface of the reinforcing member 2 coincides with the inner wall of the central shaft hole of the gear 1. The central shaft hole of the gear 1 is arranged in a regular polygon shape. In this embodiment, the shaft hole of the gear 1 is arranged in a square shape, and the inner wall of the reinforcing member 2 is also arranged in a square shape. The reinforcing member 2 is arranged in a ring shape or a polygonal ring shape. In this embodiment, the outer edge of the reinforcing member 2 is arranged in a square shape.

[0020] Operation principle: Use a machine to stretch the gear 1. While reducing its thickness, make the redundant material stretch along the edge of the shaft hole in the gear 1 to form a reinforcing member 2, and the reinforcing member 2 and the gear 1 are integrally formed.
