Description

Technical Field

[0001] This invention relates to a multifunctional cardboard box unpacking and recycling device. Background Technology

[0002] Beverages play an indispensable role in people's daily lives. With the rapid development of industry, boxed beverage production occupies a significant share of the beverage market. The reprocessing of boxed products as raw materials is also very common, such as a series of fish maw derivatives, primarily using fish maw. Milk is a highly perishable nutritional food, so most manufacturers choose to use room-temperature boxed milk, opening and using it immediately to ensure product quality. As a process in assembly line production, the demand for boxed milk is continuous. From unpacking to collecting milk and then collecting waste boxes, a lot of time and effort is required. During the unpacking process, liquid splashing can occur, resulting in material waste, and the liquid remaining in the cardboard boxes can hinder subsequent recycling. Summary of the Invention

[0003] This invention provides a multifunctional cardboard box unpacking and recycling device, which can effectively solve the above-mentioned problems.

[0004] This invention is implemented as follows:

[0005] A multifunctional cardboard box unpacking and recycling device includes a frame, an operating platform, adjustable feet, adjustable casters, an emergency stop control box, an electrical control box, a button control box, and running indicator lights. The operating platform is fixedly mounted on the top of the frame. The adjustable feet and casters are mounted on the frame. The emergency stop control box and button control box are mounted on the operating platform. The electrical control box is located in the middle of the frame. Running indicator lights for fault detection are also included.

[0006] A conveying mechanism is provided on the operating table and is used to convey paper boxes;

[0007] A limiting mechanism is provided on one side of the conveying mechanism to limit the paper box;

[0008] A puncturing device, which is mounted on the limiting mechanism, is used to puncture the cardboard box and release air pressure;

[0009] A cutting mechanism, located on the other side of the conveying mechanism, is used to cut the cardboard box and release liquid;

[0010] An expansion mechanism, located after the cutting mechanism, is used to enlarge the cutting opening and increase the liquid release. The expansion mechanism includes a first expansion blade, a second expansion blade, and a third expansion blade, which are sequentially fixedly connected. The first expansion blade includes an inclined portion. Both the second and third expansion blades have hollowed-out grooves, and the connecting section between the second and third expansion blades has an outward protrusion. The second and third expansion blades have an inclination angle B, where 15 degrees ≤ B ≤ 140 degrees. The conveying mechanism is inclined towards the button operation box and the emergency stop operation box, and has an inclination angle A, where 15 degrees ≤ A ≤ 25 degrees.

[0011] A flattening mechanism, located at the end of the conveying mechanism, is used to collect and flatten the cardboard box.

[0012] As a further improvement, the conveying mechanism includes a support frame, a first motor mounted on the support frame, a conveyor belt located in the middle of the support frame, and a placement component mounted on the conveyor belt.

[0013] As a further improvement, the placement component includes a storage box body with several screw holes, at least two strip grooves are provided on the storage box body and in front of and behind the screw holes, a connecting rod is provided in the strip grooves, and a pulley is rotatably provided on the connecting rod.

[0014] As a further improvement, the cutting mechanism includes a mounting frame, a second motor fixedly mounted on the mounting frame, a shaft fixedly connected to the output end of the second motor, and a cutting disc fixedly mounted on one end of the shaft.

[0015] As a further improvement, it also includes a strip plate disposed on the top of the mounting frame, a first rod fixedly disposed on the strip plate, and a first limiting rod fixedly connected to one end of the first rod. The first limiting rod restricts the cardboard box, so that the cardboard box in the initial state is fixed in the storage box.

[0016] As a further improvement, a collection element for collecting liquid inside the cardboard box is provided on the support and adjacent to the cutting mechanism, and a filter element used in conjunction with the collection element can filter the liquid and collect it further.

[0017] As a further improvement, the limiting mechanism includes a vertical plate, a horizontal plate fixedly connected to the vertical plate, a second rod disposed on the horizontal plate, and a second limiting rod fixedly disposed at one end of the second rod.

[0018] As a further improvement, the flattening mechanism includes a cover covering the output port, a housing disposed below the output port, a roller disposed inside the housing, and a protrusion fixedly disposed on the roller.

[0019] The beneficial effects of this invention are:

[0020] (1) When the expansion and dismantling mechanism designed in this invention comes into contact with the paper box cut, it can tear the paper box cut towards the inside of the paper box as the conveyor belt moves, so that one corner of the paper box can be separated and folded more easily, thereby allowing the liquid inside the paper box to be completely discharged, which is convenient for subsequent recycling. At the same time, the pressure inside the paper box is reduced by using the punching device, ensuring that the liquid will not splash during cutting. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to represent selected embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] In the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0041] Reference Figure 1-6 As shown, a multifunctional cardboard box unpacking and recycling device includes a frame 1, an operating table 2, adjustable feet 3, adjustable casters 4, an emergency stop control box 5, an electrical control box 6, a button control box 7, and a running indicator light 15. The operating table 2 is fixedly installed on the top of the frame 1. The adjustable feet 3 and adjustable casters 4 are installed on the frame 1. The emergency stop control box 5 and button control box 7 are installed on the operating table 2. The electrical control box 6 is installed in the middle of the frame 1, and the running indicator light 15 is used for fault detection.

[0042] The conveying mechanism 8 is set on the operating table 2 and is used to convey paper boxes; the conveying mechanism 8 includes a support 80, a first motor 81 is set on the support 80, a conveyor belt 82 is set in the middle of the support 80, and a placement member 83 is set on the conveyor belt 82.

[0043] The placement component 83 includes a storage box body 830, which has several screw holes 831. At least two strip-shaped grooves 832 are provided on the storage box body 830 and located in front of and behind the screw holes 831. A connecting rod 833 is disposed within the strip-shaped grooves 832, and a pulley 834 is rotatably mounted on the connecting rod 833. Further, the coefficient of friction of the pulley 834 is between 0.05 and 0.10. In one embodiment, the coefficient of friction of the pulley 834 is approximately 0.08.

[0044] Furthermore, the 834 pulley is made of stainless steel, which can effectively increase the sliding speed of the cardboard box.

[0045] It should be noted that an elastic element (not shown in the figure) is provided at the closed end of the storage box 830. When the cardboard box is placed into the storage box 830, the cardboard box is squeezed against the elastic element. At the same time, the first limiting rod 107 in the cutting mechanism 10 can just abut the cardboard box to prevent it from popping out directly. With subsequent operations, after all the liquid in the cardboard box has been discharged and the cardboard box is separated from the first limiting rod 107 and the second limiting rod 133, the compressed elastic element can directly pop the cardboard box out. In conjunction with the pulley 834, the acceleration of the cardboard box is increased to ensure that the cardboard box does not remain in the storage box 830.

[0046] The elastic element can be a spring, a pneumatic component (airbag or air cushion), or an elastic metal wire, etc. The specific choice can be made according to actual needs, which will not be elaborated on here.

[0047] Furthermore, the conveying mechanism 8 is inclined toward the button operation box 7 and the emergency stop operation box 5, and has an inclination angle A, where 15 degrees ≤ A ≤ 25 degrees. In one embodiment, the inclination angle A is approximately 23 degrees. If the angle is too large, the cardboard box will slip off too easily; if the angle is too small, the cardboard box may not be able to slip off from the storage box 830, thus affecting the subsequent flattening process.

[0048] It should be noted that the entire structure of the conveyor mechanism 8 is tilted, which facilitates the subsequent dropping of the cardboard boxes.

[0049] The limiting mechanism 13 is disposed on one side of the conveying mechanism 8 and is used to limit the paper box. The limiting mechanism 13 includes a vertical plate 130, a horizontal plate 131 fixedly connected to the vertical plate 130, a second rod 132 disposed on the horizontal plate 131, and a second limiting rod 133 fixedly disposed at one end of the second rod 132.

[0050] The punching device 9 (existing technology, which will not be described in detail here) is set on the limiting mechanism 13 and is used to puncture the cardboard box and release air pressure.

[0051] The cutting mechanism 10 is located on the other side of the conveying mechanism 8 and is used to cut the cardboard box and release liquid. The cutting mechanism 10 includes a mounting frame 100, a second motor 102 fixedly mounted on the mounting frame 100, a shaft 103 fixedly connected to the output end of the second motor 102, and a cutting blade 104 fixedly mounted on one end of the shaft 103. It also includes a strip plate 105 mounted on the top of the mounting frame 100, a first rod 106 fixedly mounted on the strip plate 105, and a first limiting rod 107 fixedly connected to one end of the first rod 106. The cardboard box is restricted by the first limiting rod 107, so that the cardboard box in the initial state is fixed inside the storage box 830.

[0052] The expansion mechanism 17 is disposed after the cutting mechanism 10 and is used to enlarge the cutting opening and increase the liquid release. The expansion mechanism 17 includes a first expansion blade 170, a second expansion blade 171 and a third expansion blade 172 that are fixedly connected in sequence. The first expansion blade 170 includes an inclined portion 173. The second expansion blade 171 and the third expansion blade 172 are both formed with hollow grooves 174, and the connecting section of the second expansion blade 171 and the third expansion blade 172 forms an outward protrusion 175.

[0053] Furthermore, the second and third expanding blades 171 and 172 are inclined at an angle B, wherein 15 degrees ≤ B ≤ 140 degrees. In one embodiment, the angle B is approximately 135 degrees. If the angle is too small, the second expanding blade 171 will lift the cardboard box as the cut is widening, preventing the next process from proceeding; if the angle is too large and tends to be parallel, the cut will not widen.

[0054] Furthermore, in actual use, when the cardboard box is cut with a small opening by the cutting blade 104 and one corner of the cardboard box is separated from the main body, the corner of the cardboard box will then be inserted into the first expanding blade 170. The inclined part 173 on the first expanding blade 170 further deepens the cut of the cardboard box. Then, as the second expanding blade 171 has a certain angle, when the cardboard box moves, the corner of the cardboard box can be folded down by the second expanding blade 171 with a certain angle, thereby expanding the cut and increasing the output of liquid. The parallel third expanding blade 172 keeps the corner of the cardboard box in a folded state until the cardboard box is completely separated from the expanding mechanism, thereby ensuring that the liquid in the cardboard box continues to be output to the maximum extent.

[0055] Furthermore, when the protrusion 175 on the second deflector blade 171 comes into contact with the cardboard box cut, it can tear the cardboard box cut toward the inside of the cardboard box as the conveyor belt 82 moves, making it easier to separate and fold one corner of the cardboard box.

[0056] A collection element 11 for collecting liquid inside the cardboard box is provided on the support 80 and adjacent to the cutting mechanism 10. A filter element 12 is used in conjunction with the collection element 11 to filter the liquid and collect it further.

[0057] A flattening mechanism 14 is disposed at the end of the conveying mechanism 8 for collecting and flattening paper boxes. The flattening mechanism 14 includes a cover 140 covering the output port 16, a housing 141 disposed below the output port 16, a roller 142 disposed inside the housing 141, and a protrusion 143 fixedly disposed on the roller 142.

[0058] The machine housing 141 contains two sets of rollers 142, one above the other, which are parallel and opposite to each other. The upper roller 142 has protrusions 143, which can increase the friction with the contact surface of the paper box, helping to squeeze and flatten the paper box more effectively. At the same time, the protrusions 143 can form more obvious indentations on the paper box, which helps the paper box to be folded or flattened more easily. Furthermore, the protrusions 143 can also more effectively control the movement of the paper box and prevent the paper box from sliding during the squeezing process, thus helping to flatten the paper box. The lower roller 142 has a smooth surface and no protrusions 143, which reduces wear, extends the maintenance cycle and service life, and reduces maintenance costs. At the same time, the operation of the smooth lower roller 142 reduces energy loss, thus achieving an overall energy-saving effect.

[0059] Furthermore, when flattening the cardboard box, the protrusions 143 of the upper roller 142 can form clear indentations on the cardboard box, which helps to flatten the cardboard box more thoroughly, while the smooth lower roller 142 ensures that the cardboard box will not be torn during the flattening process. The clear indentations help the cardboard box to be further processed in the subsequent recycling process, such as cutting or packing, thus improving recycling efficiency. Moreover, the protrusions of the upper roller 142 help to press the fold lines of the cardboard box tighter, reducing the generation of paper scraps during the flattening process.

[0060] Working principle of the invention:

[0061] The cardboard box is placed in the storage box 830, and the first motor 81 is turned on, causing the conveyor belt 82 to start running. The cardboard box begins to move with the conveyor belt 82. During this movement, the punching device 9 is activated, punching a row of holes in the cardboard box to release the internal pressure. Simultaneously, the second motor 102 drives the shaft 103 to rotate, which in turn drives the cutting blade 104 to rotate and cut a corner of the cardboard box. Once the corner is cut open, the conveyor belt 82 continues to move, and the corner of the cardboard box comes into contact with the first expanding blade 170, and then with the second expanding blade 171. The second expanding blade 171 folds the corner of the cardboard box downwards, continuously expanding the bottom opening of the cardboard box and increasing the liquid output. The third expanding blade keeps the folded corner of the cardboard box folded until the liquid has drained completely and is then fed into the collection container. Inside component 11, the design of the hollow groove 174 ensures that the liquid is not blocked, improving the liquid output efficiency. Then, after the liquid output is completed, as the conveyor belt 82 moves, the paper box gradually disengages from the second limiting rod 133 in the limiting mechanism 13 and the first limiting rod 107 in the cutting mechanism 10. After the paper box disengages from the second limiting rod 133 and the first limiting rod 107, the pulley 834 in the storage box body 830 will directly drive the paper box to slide down, increasing the downward speed of the paper box, so that the paper box can be transported into the flattening mechanism 14 and subsequent operations can be performed on the paper box.

[0062] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
