Description

Technical Field

[0001] The utility model relates to a recycling device, in particular to a waste blade recycling box. Background Art

[0002] In the initial roll section of the tissue machine production section, each shift will produce unqualified paper rolls and residual rolls. There are paper core tubes in the paper rolls and paper core rollers in the residual rolls. When dealing with these unqualified paper rolls and residual rolls, it is necessary to use a utility knife to cut the paper and take out the paper core tubes and paper core rollers, and then put the cut paper into the pulping tank for recycling. After the tip of the utility blade used for cutting paper becomes blunt after being used for a period of time, it needs to be broken according to the line on the blade to create a new blade for easy use. When breaking the blade manually, the broken blade is easy to bounce off, which poses a safety hazard. If the broken blade is not collected in time, it is easy to fall into the pulping tank, damage the pulping machine, and affect normal production.

[0003] The utility model patent with publication number CN 212123583 U discloses a broken blade collection device, in which a drawer-type accommodating chamber is arranged inside a box body, and a blade breaking opening is arranged on the top of the box body. A utility knife inserted into the blade breaking opening is held and tilted so that the blade of the utility knife is broken and accommodated in the accommodating chamber. The accommodating chamber is sleeved in the box body. When the blade breaks, it is easy to fly into the gap between the two, requiring an additional cleaning step, which increases the risk; the utility model patent application with publication number CN220350514 U discloses a discarded blade collector. In this scheme, the box body fixing device is arranged on the box body of the storage box. When cleaning, the shell needs to be removed, which is troublesome to disassemble. Utility Model Content

[0022] The technical solution of the utility model is further described below in conjunction with the accompanying drawings.

[0023] Example 1: Figures 1 to 3 As shown, the waste blade recycling box is mainly composed of an inner tube 1 and an outer tube 2. The inner tube 1 is inserted into the outer tube 2 from the top of the outer tube 2. The top of the inner tube 1 is closed and has a slit 3. The slit 3 is used to break the blade. The slit 3 is L-shaped to facilitate breaking the blade from multiple directions. The slit can also be other shapes. A pin 4 is provided on one side wall of the inner tube 1. The pin 4 is used to fix the inner tube 1 to the wall column. The pin 4 can be a screw. The number of the pins 4 is not less than 2 to ensure the stability of the connection of the inner tube 1.

[0024] Hooks 6 are provided at both ends of the outer cylinder 2 for hanging the outer cylinder 2 on the inner cylinder 1 so that the outer cylinder 2 is fixed. When enough blades are collected inside the outer cylinder 2, the outer cylinder 2 can be directly removed for cleaning. A gasket 5 is provided outside the pin 4, and the thickness of the gasket 5 is greater than the thickness of the outer cylinder 2, so as to facilitate the installation and removal of the outer cylinder 2. During assembly, the gap between the inner cylinder 1 and the outer cylinder 2 opens downward, away from the slit for breaking the blade, and the blade is not easy to enter the gap.

[0025] The inner tube 1 and the outer tube 2 are provided with grooves 7 at corresponding ends, and the hooks 6 are connected to the grooves.

[0026] A viewing window is provided on the front plate of the inner cylinder 1, and the viewing window is made of a transparent material, which can be glass or plastic, so as to facilitate observation of the amount of blades recycled in the recycling box and facilitate timely cleaning. The viewing window is detachably connected to the inner cylinder, and when installing the inner cylinder 1, the viewing window can be removed first, and then installed after the installation is completed.

[0027] The longitudinal sections of the inner cylinder 1 and the outer cylinder 2 are polygonal. When connected to a plane wall, at least one side wall of the inner cylinder 1 and the outer cylinder 2 is a plane to increase the connection area between the recycling box and the wall. Taking a quadrilateral as an example, the longitudinal sections of the inner cylinder 1 and the outer cylinder 2 are trapezoidal, wherein the pin 4 is arranged on the bottom surface of the inner cylinder 1 to increase the contact area between the recycling box and the wall.

[0028] like Figure 4 As shown, a flexible connecting piece 8 is provided at the bottom of the side wall of the inner cylinder 1 to facilitate the insertion of the outer cylinder 2 and to make the inner cylinder 1 and the outer cylinder 2 fit closely together.

[0029] Example 2: Figure 5 and Figure 6As shown, in this embodiment, there can also be the following variations: the back plate of the inner cylinder 1 is made of elastic material, which can be plastic or metal sheet, and the top surface of the inner cylinder 1 is provided with an arc-shaped notch that matches the cylindrical surface, and when connected to the column, the elastic back plate can fit the arc-shaped cylindrical surface. Similarly, the corresponding back plate of the outer cylinder 2 is made of elastic material and is an arc-shaped side wall, so that it can be easily sleeved on the inner cylinder 1, and a flexible sheet connecting sheet 8 is provided at the bottom of the inner cylinder 1 to facilitate the insertion of the outer cylinder 2 and make the inner cylinder 1 and the outer cylinder 2 fit together.
