[0023] The present invention will be described in further detail below with reference to the accompanying drawings.

[0024] Example:

[0025] Reference Figure 1 - Figure 5 The utility model discloses a recycling device for packaging box cardboard waste, including a shell 1, a working chamber 2 is opened in the shell 1, a conveyor belt 3 for conveying cardboard is provided in the working chamber 2, the working chamber 2 is located above the conveyor belt 3 and is connected to a dewatering component 4, the working chamber 2 is located on one side of the shell 1 and is connected to a crushing component 5 for breaking the cardboard, the shell 1 is located below the crushing component 5 and is opened with a discharge port 6, the shell 1 is located on the side of the conveyor belt 3 away from the crushing component 5 and is opened with a feed port 7.

[0026] In this embodiment, the packaging box is inevitably susceptible to moisture, impact, and other external factors during use, causing deformation of the cardboard. This can reduce the box's protective capabilities and affect its continued use. Furthermore, moisture softens the fibers of the cardboard, preventing the crushing wheel 51 from effectively cutting the cardboard during crushing. This causes the softened cardboard to stick to the crushing wheel 51 or the sidewalls of the working chamber 2, affecting the crushing effect. Therefore, dehydration is required before crushing the box.

[0027] Therefore, observe Figure 2It can be found that a dehydration component 4 is provided in the working chamber 2, so that when the recycling device for packaging box cardboard waste is used, the cardboard is put in through the feed port 7, and then the cardboard is pulled forward by the conveyor belt 3, and then the cardboard is observed. Figure 4 and Figure 5 It can be found that when the cardboard comes into contact with the dehydration component 4, it will be squeezed by the dehydration component, squeezing out the internal moisture, which can effectively reduce the moisture in the cardboard. At the same time, after the cardboard is flattened by the dehydration component, the fiber spacing in the cardboard is reduced, which will increase the hardness of the cardboard, making it easier for the crushing component 5 to exert force when breaking the cardboard, which can effectively improve the crushing effect of the cardboard and increase the crushing and recycling efficiency of the cardboard.

[0028] Finally, the crushed cardboard debris will be discharged at the discharge port 6 to complete the entire cardboard recycling process.

[0029] In a further preferred embodiment of the present invention, Figure 2 As shown, the dehydration component 4 includes an elastic member 41, a connecting seat 42 and a squeezing roller 43. The squeezing roller 43 is arranged above the conveyor belt 3. Both ends of the squeezing roller 43 are connected to the connecting seat 42 through a rotating shaft. The top of the connecting seat 42 is connected to the inner top wall of the working chamber 2 through an elastic member 41.

[0030] In this embodiment, different types of conveyed goods require different levels of protection, so different types of cardboard are used. If the spacing between the squeezing roller 43 and the conveyor belt 3 is too large, the dehydration effect of thinner cardboard will be reduced. If the spacing is too small, thicker cardboard will be over-squeezed and crushed on the conveyor belt 3. As a result, broken cardboard debris will stick to the conveyor belt 3 and be sucked into the rotating shaft, affecting the use of the conveyor belt 3.

[0031] Therefore, connecting bases 42 are connected to each end of the squeezing roller 43 via rotating shafts. A spring member 41 is installed between the top of the connecting base 42 and the working chamber 2. The elasticity of the spring member 41 automatically adjusts the thickness of the cardboard. When the cardboard is thick, the squeezing roller 43 will also experience a greater support force from the cardboard when squeezing it. The deformation of the spring member 41 causes the squeezing roller 43 to move upward, ensuring the squeezing and dehydration effect while protecting the integrity of the cardboard. Furthermore, because the provision of the spring member 41 can reduce the distance between the squeezing roller 43 and the conveyor belt 3, even thinner cardboard can be squeezed and dehydrated normally, effectively improving the practicality of the packaging box cardboard waste recycling device.

[0032] In a further preferred embodiment of the present invention, Figure 3As shown, the elastic member 41 includes a sleeve 411, a connecting rod 412 and a spring 413. The top of the sleeve 411 is fixedly connected to the inner top wall of the working chamber 2. The sleeve 411 is slidably connected with a connecting rod 412 fixedly connected to the connecting seat 42. A spring 413 is provided between the top of the connecting seat 42 and the sleeve 411, and the spring 413 is sleeved on the outside of the connecting rod 412.

[0033] In this embodiment, since the squeezing roller 43 needs to adjust the distance between it and the conveyor belt 3 according to the thickness of the cardboard, the squeezing roller 43 needs to be able to move upward, so the observation Figure 3 It can be found that a connecting rod 412 is provided on the top of the connecting seat 42, and a sleeve 411 is sleeved on the top of the connecting rod 412. The connecting rod 412 can slide in the sleeve 411 to enable the squeezing roller 43 to move.

[0034] In order to ensure that the squeezing roller 43 applies sufficient pressure to the cardboard for dehydration, the squeezing roller 43 needs to have the ability to resist the supporting force of the cardboard. Therefore, a spring 413 is provided between the connecting seat 42 and the sleeve 411. The elastic force of the spring 413 is used to enable the squeezing roller 43 to obtain downward squeezing pressure, thereby ensuring that the squeezing roller 43 applies pressure to the cardboard for dehydration, and making the squeezing roller 43 more effective in squeezing the cardboard.

[0035] In a further preferred embodiment of the present invention, Figure 2 As shown, circular holes 8 for drainage are evenly distributed on the surface of the conveyor belt 3 , and an electric heating block 9 for drying cardboard is fixedly connected to the inner wall of the working chamber 2 in the middle of the conveyor belt 3 .

[0036] In this embodiment, because the cardboard is placed on the conveyor belt 3, when the cardboard is squeezed and dehydrated, water will remain on the conveyor belt 3 and be reabsorbed by the cardboard after the cardboard loses the squeeze, so it is observed that Figure 2 It can be found that the conveyor belt 3 is evenly distributed with round holes 8, which can allow the squeezed water to be discharged along the round holes, and can effectively prevent the water from being absorbed again by the cardboard.

[0037] Because the liquid itself has tension, part of the squeezed water will remain in the contact area between the cardboard and the conveyor belt 3, affecting the dehydration effect. Therefore, an electric heating block 9 is provided in the working chamber 2 located in the middle of the conveyor belt 3. After the cardboard is dehydrated, the surface moisture will be dried under the high temperature of the electric heating block 9, which can further improve the dehydration effect of the cardboard, thereby making the cardboard crushing effect better and further improving the recycling efficiency of the cardboard.

[0038] In a further preferred embodiment of the present invention, Figure 2As shown, the inner wall of the working chamber 2 is rotatably connected to multiple groups of support rollers 10 at equal intervals along the horizontal direction. The support rollers 10 are located above the electric heating block 9 and in contact with the inner wall of the conveyor belt 3.

[0039] In this embodiment, because the conveyor belt 3 is made of flexible material, the conveyor belt 3 will be deformed and concave when the dehydration component 4 squeezes the cardboard, affecting the dehydration efficiency of the cardboard. Figure 2 It can be found that multiple groups of support rollers 10 are rotatably arranged in the working chamber 2. The support rollers 10 are used to provide support for the conveyor belt 3, which can effectively prevent the conveyor belt 3 from deforming when the dehydration component 4 squeezes the cardboard, thereby ensuring the dehydration effect of the cardboard.

[0040] In a further preferred embodiment of the present invention, Figure 2 As shown, the crushing assembly 5 includes a crushing wheel 51, a drive motor 52 and a transmission unit 53. Two crushing wheels 51 are provided and symmetrically arranged in the working chamber 2. The same side of the two crushing wheels 51 is connected to the transmission unit 53 through a rotating shaft, and one side of the transmission unit 53 is connected to the drive motor 52.

[0041] In this embodiment, the drive motor 52 is provided to drive the crushing wheels 51 to rotate, so that the two crushing wheels 51 cut the cardboard into pieces, and the transmission unit 53 is provided to make the two crushing wheels 51 rotate synchronously in opposite directions, so that the two crushing wheels 51 can better crush the cardboard and improve the crushing efficiency.

[0042] The transmission unit 53 may be a transmission assembly such as a gearbox plus gears, a gearbox plus pulleys, etc., which enables the two output shafts to rotate in opposite directions.

[0043] In a further preferred embodiment of the present invention, Figure 2 As shown, two sets of guide plates 11 are fixedly connected to the inner wall of the working chamber 2, and the two guide plates 11 are respectively arranged above the two crushing wheels 51, and the top of one of the guide plates 11 close to the conveyor belt 3 is lower than the conveying plane of the conveyor belt 3.

[0044] In this embodiment, by providing two sets of guide plates 11, and the two sets of guide plates 11 are respectively arranged above the two crushing wheels 51, the cardboard entering the crushing assembly 5 can be guided by the guide plates 11 and enter between the two crushing wheels 51, so that the two crushing wheels 51 can better roll the cardboard into the crushing gap, which can effectively improve the crushing efficiency of the cardboard.

[0045] By making the top of the guide plate 11 close to the conveyor belt 3 lower than the conveying plane of the conveyor belt 3, the cardboard conveyed by the conveyor belt 3 will not be blocked by the guide plate 11 and thus will not be affected in conveying the cardboard.

[0046] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
