Description

Technical Field

[0001] The utility model relates to the technical field of paper shredding equipment, in particular to a waste paper shredding and storage box for project cost. Background Art

[0002] During the project cost period, since staff use a large amount of paper for cost calculation, a large amount of waste paper will be generated in this process. However, the surface of the waste paper may contain confidential information about the project cost. Therefore, the waste paper generated during the project cost cannot be discarded at will. Generally, the discarded paper needs to be shredded to prevent the leakage of document information and cause losses to the enterprise. Office shredders are the most commonly used waste paper shredding and storage devices at present.

[0003] However, when the current office shredders on the market are in use, the following problems generally exist: After the user sorts out the waste paper and sends it into the paper inlet, due to the relatively shallow depth of the paper inlet and the fact that the single paper shredding process takes several seconds to complete, in order to prevent the waste paper (taking the most common A4 paper as an example) from bending and hanging on the shredder during the paper feeding process and affecting the paper feeding effect, the user often needs to hold the top of the waste paper by hand. After the waste paper enters half (or even two-thirds) of the paper inlet, let go, and then rely on the toughness of the paper itself to make the remaining paper naturally enter the paper inlet in a slightly bent state, and finally complete the single paper shredding operation.

[0004] In the above process, in addition to putting the paper into the paper inlet, the user mainly spends time on assisting the paper feeding. First, it delays the user from getting the paper later. Second, it increases the labor time and affects the use experience. If the amount of shredded paper is large, the impact on the user experience is more obvious.

[0005] There are high-end shredders with a batch paper feeding function on the market at present, but they all adopt an internal paper feeding method. When in use, the top cover of the shredder needs to be opened, then a thick stack of paper is put into the paper feeding slot, and then the machine cover is closed to start the shredding operation. However, due to the working principle of the shredder itself, no matter how many papers are put in at one time, whether it is a dozen or several dozen or even hundreds of papers, the upper limit of the number of shredded papers in a single paper shredding process remains unchanged. Therefore, for a shredder with a batch paper feeding function, a supporting auxiliary paper feeding mechanism needs to be installed inside to send the batch of papers into the shredding mechanism for shredding in batches. This results in that the shredder with a batch paper feeding function has a complex structure and a high price. Content of the Utility Model

[0006] The purpose of the utility model is to solve the problem that the existing paper shredding lacks an auxiliary paper feeding function and affects the user experience, and to propose a waste paper shredding and storage box for project cost.

[0007] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0008] A waste paper shredding and storage box for project cost, comprising a shredder body. A paper inlet is provided at the top of the shredder body. A rotatable paper guide is provided at the top of the paper inlet. The paper guide includes a paper guide cylinder communicating with the paper inlet. Support arms are provided on both sides of the paper guide cylinder. The paper guide cylinder is rotatably installed on the shredder body through the support arms.

[0009] Further, a storage groove is formed at the top of the shredder body. The storage groove includes a paper cylinder groove for storing the paper guide cylinder and a support arm groove communicating with the paper cylinder groove. Guide blocks are provided on the inner wall of the support arm groove. Corresponding guide grooves are provided on the side wall of the support arm. The support arm is rotatably installed in the support arm groove through the cooperation of the guide block and the guide groove.

[0010] Further, an anti-slip pad is provided at a position on the support arm groove outside the guide block. The anti-slip pad abuts against the inner wall of the support arm.

[0011] Further, the support arm groove includes a horizontal groove and a vertical groove. The ends of the horizontal groove and the vertical groove are connected. The guide block is located at the corner where the horizontal groove and the vertical groove are connected. The guide groove is an oblong groove.

[0012] Further, the paper guide cylinder is a straight cylinder structure with openings at both the top and the bottom. A handle groove is formed on the front wall of the paper guide cylinder.

[0013] Further, the paper guide cylinder is of a transparent structure.

[0014] Further, an operation panel is provided at a position in front of the paper inlet at the top of the shredder body.

[0015] Further, a paper collection structure is provided at the lower part of the shredder body. The paper collection structure includes a paper collection box, a box chamber door, and a storage barrel. A box chamber door is provided in front of the paper collection box. A storage barrel is provided inside the paper collection box.

[0016] Further, a password lock is provided on the box chamber door.

[0017] Compared with the prior art, the present utility model provides a waste paper shredding and storage box for project cost, having the following beneficial effects:

[0018] When using the waste paper shredding and storage box for project cost of the present utility model, rotate the paper guide cylinder to communicate with the paper inlet, and send waste paper into the paper inlet through the paper guide cylinder. After releasing the hand, the waste paper is kept slightly bent by the paper guide cylinder and can naturally enter the paper inlet state. The user can continue to take paper, avoiding the situation that the user needs to keep holding the waste paper all the time, improving the user experience. After shredding, the shredded waste paper is stored inside the shredder body. Then rotate the paper guide to a non-working state and lower the height of the paper guide to save space occupancy.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0029] Referring to Figures 1-6 , a waste paper shredding and storage box for a project cost of the present utility model includes a shredder body 1. A paper inlet 101 is installed at the top of the shredder body 1. The paper inlet 101 is communicated with the shredding mechanism inside the shredder body 1. Waste paper enters the shredding mechanism through the paper inlet 101 for shredding. Generally, in a single shredding process, the paper intake of the paper inlet 101 ranges from several sheets to more than a dozen sheets.

[0030] A rotatable paper guide 2 is installed at the top of the paper inlet 101. The paper guide 2 includes a paper guide cylinder 201 corresponding to and communicating with the paper inlet 101. During use, the waste paper that has been broken once is fed into the paper inlet 101 through the paper guide cylinder 201 and enters the crushing mechanism. Then, release the hand. Relying on the auxiliary support of the paper guide cylinder 201 for the waste paper, prevent the part of the waste paper that has not entered the paper inlet 101 from bending and sagging, so that the waste paper can rely on its own toughness and the support of the paper guide cylinder 201 to maintain a slightly bent state without affecting the paper feeding effect.

[0031] Support arms 202 are fixedly connected to both the left and right sides of the paper guide cylinder 201. The support arms 202 are rotatably connected to the shredder body 1. The paper guide cylinder 201 is rotatably installed on the shredder body 1 through the support arms 202. When the support arms 202 rotate, the paper guide cylinder 201 is switched between the working state and the non-working state. When the paper guide cylinder 201 is in the working state or the non-working state, the support arms 202 remain fixed at the corresponding positions.

[0032] When the paper guide cylinder 201 rotates to be vertically and vertically connected, it is in the working state. When the paper guide cylinder 201 rotates to be horizontally and horizontally connected, it is in the non-working state. When shredding is required, the paper guide cylinder 201 rotates to the working state, and the bottom of the paper guide cylinder 201 is aligned and communicated with the paper inlet 101. After use, the paper guide cylinder 201 rotates to the non-working state to save space occupation. After the waste paper is shredded, it is stored in the storage bucket 403 inside the shredder body 1.

[0033] A storage groove 5 is opened and processed at the top of the shredder body 1. The storage groove 5 has an open top. The storage groove 5 includes a paper cylinder groove 501 for storing the paper guide cylinder 201 and a support arm groove 502 communicating with the paper cylinder groove 501. A guide block 504 is installed on the inner wall of the support arm groove 502. The guide block 504 is cylindrical. A guide groove 203 corresponding to the guide block 504 is processed on the side wall of the support arm 202. The height dimension of the guide groove 203 (or the width dimension in the front-rear direction in the vertical state) is the same as the outer diameter dimension of the guide block 504. The guide groove 203 and the guide block 504 are rotatably connected. The support arm 202 is rotatably installed in the support arm groove 502 through the cooperation of the guide block 504 and the guide groove 203.

[0034] During use, pull the paper guide cylinder 201, and the support arm 202 rotates around the guide block 504, and the paper guide cylinder 201 rotates upward to communicate with the paper inlet 101.

[0035] An anti-slip pad 506 is installed at a position on the support arm groove 502 outside the guide block 504. The anti-slip pad 506 abuts against the inner wall of the support arm 202, enabling the support arm 202 to squeeze the anti-slip pad 506 to increase friction. After the support arm 202 rotates to the vertical state, waste paper is placed into the paper guide tube 201. During the paper feeding process of the waste paper, the friction between the support arm 202 and the anti-slip pad 506 prevents the paper guide 2 from freely rotating, fixing the paper guide tube 201 at the top of the paper inlet 101.

[0036] The support arm groove 502 includes a horizontal groove 503 and a vertical groove 505. The front end of the horizontal groove 503 (such as Figure 1 the shown chamber door is located at the front end of the shredder body 1) is connected to the top end of the vertical groove 505. The guide block 504 is located at the middle position of the corner where the horizontal groove 503 and the vertical groove 505 are connected. The guide groove 203 is an oval groove, and the width of the oval groove is the same as the outer diameter dimension of the guide block 504. The guide groove 203 is rotationally and slidably connected to the guide block 504. After the support arm 202 rotates to the vertical state, it then penetrates downward into the vertical groove 505, and the guide groove 203 slides on the surface of the guide block 504. Through the cooperation of the vertical groove 505 and the guide block 504, the paper guide 2 is stably maintained in the vertical state.

[0037] The paper guide tube 201 has a straight tube structure with openings at both the top and bottom, and the cross-section of the paper guide tube 201 in the top view angle is rectangular. The front and rear side walls and the left and right side walls of the inner wall of the paper guide tube 201 are respectively aligned with the paper inlet 101. A handle groove 204 is machined on the front wall of the paper guide tube 201, and the handle groove 204 is a through groove that penetrates the front side wall of the paper guide tube 201.

[0038] When the paper guide tube 201 needs to be lifted upward, the finger extends into the handle groove 204, and then the paper guide tube 201 can be lifted.

[0039] The paper guide tube 201 is a transparent structure and can be made of transparent plastic, which is convenient for observing the internal situation of the paper guide tube 201 during reuse, preventing the situation that foreign objects enter the paper guide tube 201 and are not discovered in time and then fall into the paper inlet 101.

[0040] An operation panel 3 is installed at a position on the top of the shredder body 1 in front of the paper inlet 101. When the paper guide tube 201 is in the vertical state, it does not affect the normal use of the operation panel 3. In the prior art, the operation panels 3 of most shredders are installed on the top of the shredder, and at the same time, other areas on the top of the shredder are in an idle state. This solution effectively improves the space utilization of the top of the shredder body 1 while slightly increasing the height of the shredder, and at the same time reserves the installation position of the operation panel 3 on the top of the shredder body 1, facilitating the upgrade and improvement of the existing shredder solution.

[0041] A paper collection structure 4 is installed at the lower part of the paper shredder body 1. The paper collection structure 4 includes a paper collection box 401, a box chamber door 402, and a storage barrel 403. The lower part of the paper shredder body 1 is processed with a paper collection box 401. A box chamber door 402 is installed in front of the paper collection box 401. The box chamber door 402 is hinged between the side wall of one side of the paper collection box 401. A storage barrel 403 is placed inside the paper collection box 401. The waste paper shredded by the paper shredding mechanism falls into the storage barrel 403.

[0042] A password lock 404 is installed at one end of the box chamber door 402 away from the hinged end. The password lock 404 can be a password lock with a fingerprint recognition function, which can prevent unauthorized personnel from taking out the shredded waste paper and further improve the security of the waste paper shredding process in this solution.

[0043] Working principle: When in use, hold the handle groove 204 and rotate the paper guide 2 upward to the vertical state. Then slide the paper guide 2 downward. The bottom end of the support arm 202 is inserted into the vertical groove 505 so that the bottom end of the paper guide cylinder 201 is docked with the paper inlet 101. Then start the paper shredder body 1. Take a single - time shredded quantity of waste paper sheets and send them into the paper inlet 101 through the paper guide cylinder 201. The bottom end of the waste paper sheets is automatically rolled in and shredded by the paper shredding mechanism. The paper guide cylinder 201 prevents the part of the waste paper that has not entered the paper inlet 101 from being severely bent. After a single - time paper shredding is completed, the user can continue to put the next batch of waste paper sheets to be shredded into the paper guide cylinder 201.

[0044] After use, turn off the paper shredder body 1. Slide the paper guide 2 upward. When the guiding block 504 contacts the bottom of the guiding groove 203, it stops the paper guide 2 from sliding upward further, preventing the support arm 202 from detaching from the support arm groove 502. Then rotate the paper guide 2 backward to store the paper guide cylinder 201 in the paper cylinder groove 501, and the support arm 202 is stored in the support arm groove 502.
