Description

Technical Field

[0001] The utility model belongs to the technical field of cardboard scrap crushing, and particularly relates to a cardboard processing waste recycling device. Background Art

[0002] Cardboard is a product material used for processing products such as cartons. Various types of packaging cartons are processed from cardboard for packaging products. Due to many advantages of cardboard, such as light texture, inexpensive and easily available materials, and degradable and recyclable, its consumption is very large in the industry and the market demand is huge.

[0003] During the production process, according to the formed cartons, holes need to be opened on the cardboard, and a large amount of cardboard waste, namely paper waste, is generated. The paper waste needs to be recycled to ensure the maximum use of materials and avoid material waste. In addition, during the production process, methods such as trimming and repairing the cardboard are also likely to generate cardboard waste. For the recycling treatment of cardboard waste, the current conventional method is to crush the cardboard waste into cardboard chips and then add them to the processing equipment again to prepare pulp.

[0004] Specifically, the cardboard waste is added to a large crusher to achieve batch processing of waste in this way. However, in the actual production process, especially when the production volume is not high, the waste (scrap) generated in the workshop is relatively small, and it takes a long time to accumulate to meet the crushing volume requirements of the large crushing equipment.

[0005] Obviously, in the actual production process, this method requires accumulating the scrap generated in the workshop and then centrally processing it. Since the cardboard scrap is not only small in volume and light in weight, it is very easy to float in the workshop under the action of wind during the stacking process in the workshop, seriously affecting the cleanliness of the workshop. Therefore, in the actual production process, the scrap generated in the workshop is cleaned every day.

[0006] And the amount of scrap cleaned is relatively small, resulting in great difficulty in crushing the scrap. Specifically, when the amount of scrap is small, it cannot be crushed by large crushing equipment, and the crushing effect of conventional small crushing equipment is not ideal. Specifically, when the scrap is poured into the small crushing equipment, since the cardboard waste is relatively light, it is difficult to be fully crushed without being compacted when placed in the crushing equipment. Even during the crushing process, paper scraps fly everywhere, resulting in an increase in the amount of debris and dust in the workshop after crushing. Summary of the Utility Model

[0007] Based on the above background, the purpose of the utility model is to provide a cardboard processing waste recycling device.

[0038] Embodiment 1

[0039] As Figures 1-5 shown, a cardboard processing corner waste recycling device includes a crushing bin 1, and a crushing mechanism for crushing cardboard corner waste is assembled and connected above the crushing bin 1.

[0040] An accommodation bin 3 communicating with the crushing bin 1 is integrally formed at the upper pipe orifice part of the crushing bin 1 (the cavity of the accommodation bin 3 communicates with the pipe cavity of the crushing bin 1, and the outer radius of the accommodation bin 3 is greater than the outer radius of the crushing bin 1), and a material pressing mechanism 4 is assembled and connected in the accommodation bin 3.

[0041] Specifically, during the crushing process, the cardboard waste is pressed down by the material pressing mechanism 4. Especially after the cardboard waste is fed, when the fluffiness of the cardboard is relatively high, under the pressing action, the compactness of the crushed material is improved, thereby enhancing the crushing effect.

[0042] Specifically, the material pressing mechanism 4 includes a number of spring sliding connectors fixedly connected to the bottom of the receiving barrel 3. A pressing plate 41 (made of stainless steel) is assembled and connected between the spring sliding connectors. Correspondingly, each spring sliding connector includes a spring rod 42 slidably connected to the pressing plate 41, and a spring 43 is sleeved on the spring rod 42.

[0043] Specifically, the spring rod 42 is slidably connected to the edge of the pressing plate 41, and a nut is threadedly connected to its upper end.

[0044] During the working process, after the pressing plate 41 is removed, the material is manually compacted after being fed (the material enters the receiving barrel 3 and the crushing barrel 1. The barrel radius of the receiving barrel 3 is 50 cm, which can accommodate the waste generated in a day's production in the workshop). Subsequently, after the pressing plate 41 is assembled, during the crushing process, the pressing plate 41 presses down the material to improve the crushing effect.

[0045] Specifically, the material with high fluffiness is continuously pressed from the receiving barrel 3 into the crushing barrel 1 under the extrusion of the pressing plate 41, and the material is fully crushed under compaction.

[0046] Embodiment 2

[0047] As Figures 1-5 shown, on the basis of the structure of Embodiment 1, a top cover component is detachably assembled and connected to the top barrel opening of the above-mentioned receiving barrel 3. The specific method is as follows: a lower mounting flange is integrally formed at the top pipe orifice of the crushing barrel 1. The top cover component includes a barrel cover body (installed in the existing conventional manner. In order to reduce the escape of scattered dust, a partition cover plate is installed on the top of the barrel cover body. The specific method is that the partition cover plate is threadedly connected to the top position of the barrel cover body). An upper mounting flange is integrally formed at the bottom of the barrel cover body; the lower mounting flange and the upper mounting flange are assembled and connected by a number of connecting screws; a pressing member for pressing against the pressing plate 41 is fixedly assembled in the barrel cover body. Specifically, the pressing member includes a U-shaped plate 51 fixedly assembled in the barrel cover body, and a pressing rod 6 is threadedly connected to the U-shaped plate 51. A driving handwheel 61 is fixedly assembled inside the pressing rod 6.

[0048] During the working process, the operator rotates the driving handwheel 61 by hand. At this time, after the pressing rod 6 descends, it touches the pressing plate 41, and thus the pressing plate 41 is kept in a pressing state through this method.

[0049] After crushing, the operator rotates the driving handwheel 61. After the pressing rod 6 is lifted, under the elastic restoring force of the spring 43, the pressing plate 41 is lifted, facilitating subsequent feeding after removing the pressing plate 41.

[0050] Embodiment 3

[0051] As Figures 1-5 shown, on the basis of the structure of Embodiment 1 in this embodiment, the above-mentioned crushing mechanism 2 includes a crushing motor 21 installed at the bottom of the crushing bin cylinder 1 (in accordance with the existing conventional method, the above-mentioned motor sleeve 11 is fixedly assembled at the bottom of the crushing bin cylinder 1). A crushing material shaft rotatably connected inside the crushing bin cylinder 1 is assembled and connected to the crushing motor 21 (in the same way as the existing method, the crushing material shaft is rotatably connected to the crushing bin cylinder 1), and a crushing knife component is assembled and connected to the crushing material shaft.

[0052] Specifically, the crushing knife component includes a shaft-shaped knife seat 22 fixedly assembled on the crushing material shaft. A plurality of crushing knives 23 are detachably assembled and connected to the outer side wall of the shaft-shaped knife seat 22. The crushing knife 23 includes a knife body, and a plurality of installation grooves for inserting the inner end of the knife body are provided on the outer side wall of the shaft-shaped knife seat 22.

[0053] A plurality of installation foot plates 221 are respectively welded to the top and bottom of the above-mentioned shaft-shaped knife seat 22. A fastening bolt for fastening to the knife body is threadedly connected to the installation foot plate 221 (this method realizes detachable assembly and facilitates replacement of the knife body).

[0054] During the working process, the crushing motor 21 is turned on. Driven by the crushing motor, at this time, the shaft-shaped knife seat 22 rotates at a high speed. Under the action of the high-speed rotating crushing knife, the material is crushed.

[0055] After crushing, after removing the above-mentioned pressing plate 41, pour out the powder, and then add materials again for crushing. In accordance with the existing conventional method, a hinge frame is hinged on the outer side wall of the crushing bin cylinder 1. After crushing, rotate the entire device so that the crushing bin cylinder 1 faces downwards, facilitating pouring the crushed debris into the storage bag.

[0056] Under the action of the pressing plate 41, during the crushing process, it is possible to prevent debris and powder from flying, so as to avoid pollution of the workshop during crushing.

[0057] Certainly, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the scope of the essence of the present invention should also fall within the protection scope of the present invention.
