Description

Technical Field

[0001] This utility model relates to the field of edge trimming machine technology, specifically a corrugated cardboard edge trimming machine with waste paper shredding function. Background Technology

[0002] In the prior art, patent document CN114952976A discloses a trimming mechanism for corrugated cardboard production, including a trimming cutter disc driven by a drive shaft, two feeding rollers disposed on one side of the drive shaft for conveying the trimmed corrugated paper edges, a first transmission assembly for driving the feeding rollers, and a shredding box disposed below the feeding rollers for shredding the collected corrugated paper edges. This mechanism can feed the trimmed corrugated paper edges into the shredding box for shredding, reducing the length of the trimmed corrugated paper. However, the above device has the following technical problems in use:

[0003] 1. Inconvenient to compress and process waste material before shredding: Existing edge trimming machines cannot effectively compress and process waste material when processing corrugated cardboard waste.

[0004] 2. Inconvenient to knead the waste material before crushing: Existing equipment is difficult to knead the corrugated cardboard waste material from multiple angles, resulting in poor recycling and reuse of the waste material, and the kneading force is insufficient and the kneading is not thorough enough;

[0005] 3. Difficulty in waste recycling and processing: In existing technologies, corrugated cardboard waste is difficult to recycle and process due to the difficulty in separating adhesive substances such as glue.

[0006] Based on this, the present invention provides a corrugated cardboard trimming machine with waste paper shredding function to solve the problems mentioned in the background art. Utility Model Content

[0007] This utility model addresses the technical problems existing in the prior art by providing a corrugated cardboard trimming machine with waste paper shredding function. This solves the problems that existing devices are not convenient for compressing and sorting waste materials before shredding, not convenient for kneading waste materials before shredding, and difficult for waste material recycling.

[0008] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A corrugated cardboard trimming machine with waste paper shredding function includes a frame and a shredder installed on the frame. A servo motor and a reciprocating compression mechanism are installed on the frame. A compression frame that can move back and forth and a rotatable slide shaft are driven and installed on the reciprocating compression mechanism. The slide shaft is rotatably installed on the compression frame. A reciprocating kneading mechanism is installed on the compression frame. A kneading frame that can move back and forth is driven and installed on the reciprocating kneading mechanism. A kneading shaft driven by the slide shaft is rotatably installed on the inner wall of the kneading frame. An active toothed roller is installed on the kneading shaft. A driven toothed roller is rotatably installed on the frame. A kneading gap is provided between the active toothed roller and the driven toothed roller. A rotary cutting disc for rotary cutting corrugated cardboard is rotatably installed on the frame. The output shaft end of the servo motor is connected to the rotary cutting disc through a first belt. An electric heating plate is fixedly installed on the frame. Both the active toothed roller and the driven toothed roller have built-in electric heating rods.

[0009] The beneficial effects of this utility model are:

[0010] 1. This utility model can effectively compress and organize waste materials before crushing. Existing edge trimming machines cannot effectively compress and organize waste materials when processing corrugated cardboard waste. However, this utility model uses a reciprocating compression mechanism to make the compression frame move back and forth on the machine frame. By utilizing the compression force between the active toothed roller and the driven toothed roller, the loose corrugated cardboard waste materials can be compressed to about one-third of their original volume, which greatly saves the temporary storage space for waste materials and provides convenience for subsequent crushing and processing, effectively solving the shortcomings of traditional equipment in this regard.

[0011] 2. This utility model facilitates thorough kneading of waste materials before crushing. Existing equipment struggles to knead waste materials from multiple angles, resulting in insufficient and inadequate kneading force, leading to poor waste recycling and reuse. The reciprocating kneading mechanism of this utility model allows the active toothed roller to move back and forth relative to the driven toothed roller, thoroughly kneading the waste materials and separating substances such as glue from the surface. Simultaneously, the V-shaped meshing teeth and surface friction patterns on the active and driven toothed rollers further enhance the kneading effect, enabling more efficient crushing and kneading of waste materials. This results in thinner and more segmented corrugated paper strips after trimming, improving the crushing effect and significantly enhancing the quality of waste recycling and reuse.

[0012] 3. This invention reduces the difficulty of waste recycling. In existing technologies, corrugated cardboard waste is difficult to recycle due to the difficulty in separating adhesive substances such as glue. This invention installs an electric heating plate on the frame, and electric heating rods are built into the driving and driven toothed rollers. When heated to 90°C, the adhesive substances such as glue on the waste are softened and the waste becomes brittle. During the kneading process, the softened glue is easier to separate, improving the adhesion of the waste. Moreover, when repressing to make new cardboard, the glue distribution is more uniform, the quality of the new cardboard is more stable, and the defect rate is reduced by about 20%, effectively solving the problem of waste recycling and improving recycling efficiency.

[0013] Based on the above technical solution, the present invention can be further improved as follows.

[0014] As a preferred technical solution of this utility model, the reciprocating compression mechanism includes a fixed transmission shaft, a belt shaft, a left gear shaft, and a right gear shaft rotatably connected to the frame. The output shaft end of the servo motor is connected to the belt shaft via a second belt. A first bevel gear is installed on both the fixed transmission shaft and the belt shaft, and the two first bevel gears mesh with each other. A first connecting groove with a tail opening and sliding connection to the fixed transmission shaft is fixedly opened inside the sliding shaft. A second bevel gear is installed on both the left gear shaft and the fixed transmission shaft, and the two second bevel gears mesh with each other. The left gear shaft is connected to the right gear shaft via a third belt. A first half gear is installed on the right gear shaft.

A fourth bevel gear is installed on the tail shaft, and the fourth bevel gear is connected to the third bevel gear on the half-tooth shaft. A second connecting groove with a tail end opening and sliding connection to the tail shaft is fixedly opened inside the kneading shaft.

[0026] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0027] The present invention provides the following preferred embodiments.

[0028] like Figures 1-5 As shown, a corrugated cardboard trimming machine with waste paper shredding function includes a frame 1 and a shredder 2 mounted on the frame 1. A servo motor 3 and a reciprocating compression mechanism are mounted on the frame 1. A compression frame 4 that can move back and forth and a rotatable slide shaft 5 are driven and mounted on the reciprocating compression mechanism. The slide shaft 5 is rotatably mounted on the compression frame 4.

[0029] Crusher 2 is a commonly used mechanism in the prior art, and will not be described in detail here;

[0030] The shredder 2 is located below the frame 1, and its feed inlet corresponds to the discharge position of the drive toothed roller 8 and the driven toothed roller 9, so as to receive the corrugated cardboard waste after compression and kneading.

[0031] The reciprocating compression mechanism includes a fixed transmission shaft 11, a belt shaft 12, a left gear shaft 13, and a right gear shaft 14 rotatably connected to the frame 1. The output shaft end of the servo motor 3 is connected to the belt shaft 12 via a second belt. A first bevel gear is installed on both the fixed transmission shaft 11 and the belt shaft 12, and the two first bevel gears mesh with each other.

[0032] The sliding shaft 5 has a first connecting groove with a tail opening and sliding connection with the fixed transmission shaft 11. A second bevel gear is installed on both the left gear shaft 13 and the fixed transmission shaft 11. The two second bevel gears mesh with each other. The left gear shaft 13 is connected to the right gear shaft 14 through a third belt.

[0033] A first half-tooth gear 15 is installed on the right gear shaft 14, and a compression tooth plate 16 that is connected to the first half-tooth gear 15 is installed on the compression frame 4. A set of first return spring assembly 17 is installed between the compression frame 4 and the frame 1.

[0034] When the servo motor 3 starts, its output shaft drives the belt shaft 12 to rotate. The first bevel gear on the belt shaft 12 meshes with the first bevel gear on the fixed transmission shaft 11, causing the fixed transmission shaft 11 to rotate.

[0035] The rotation of the fixed transmission shaft 11 drives the slide shaft 5 to rotate through the first connecting groove inside the slide shaft 5, providing power for the subsequent kneading mechanism. On the other hand, the second bevel gear on the fixed transmission shaft 11 drives the left gear shaft 13 to rotate. The left gear shaft 13 drives the right gear shaft 14 through the third belt. The first half gear 15 on the right gear shaft 14 cooperates with the compression tooth plate 16 on the compression frame 4, causing the compression frame 4 to move back and forth on the frame 1.

[0036] The first reset spring assembly 17 plays a role in buffering and resetting during the movement of the compression frame 4;

[0037] This design solves the problem that existing edge trimming machines cannot effectively perform preliminary compression and sorting of corrugated cardboard waste when processing it;

[0038] Compared with existing technologies, this solution can compress loose corrugated cardboard waste by using the compressive force between the active toothed roller 8 and the driven toothed roller 9 before crushing, thereby reducing the volume of waste and facilitating subsequent crushing.

[0039] In actual production, the waste generated by traditional edge trimming machines is piled up randomly, taking up a lot of space. However, this device can compress the waste to about one-third of its original volume through a reciprocating compression mechanism, which greatly saves the temporary storage space for waste.

[0040] A reciprocating kneading mechanism is installed on the compression frame 4. A kneading frame 6 that can move back and forth is installed on the reciprocating kneading mechanism. A kneading shaft 7 driven by a sliding shaft 5 is rotatably installed on the inner wall of the kneading frame 6.

[0041] When the sliding shaft 5 rotates, it drives the half-tooth shaft 18 installed on the compression frame 4 to rotate. The third bevel gear on the half-tooth shaft 18 meshes with the third bevel gear on the sliding shaft 5. When the half-tooth shaft 18 rotates, the two second half-tooth gears 20 installed on it are respectively connected to the two kneading tooth plates 21 on the kneading frame 6, so that the kneading frame 6 moves back and forth on the compression frame 4.

[0042] The second reset spring assembly 22 serves to buffer and reset the kneading frame 6. At the same time, the sliding shaft 5 rotates and engages with the second connecting groove inside the kneading shaft 7 through the tail shaft 19, driving the kneading shaft 7 to rotate.

[0043] This solves the problem that existing equipment is unable to perform multi-angle crumpling of corrugated cardboard waste, resulting in poor waste recycling and reuse.

[0044] Compared with the existing technology, this solution enables the active toothed roller 8 to reciprocate relative to the driven toothed roller 9 and fully rub the waste material. Through rubbing, substances such as glue on the surface of the waste material can be separated, thereby improving the quality of waste recycling.

[0045] Furthermore, through the kneading process, the corrugated paper strips cut off from the edge can be made thinner and the whole piece of corrugated paper can be divided into multiple segments, reducing the size of the corrugated paper waste. This allows the shredder 2 to quickly crush the kneaded corrugated paper strips and improve the crushing effect of the corrugated paper waste.

[0046] The first reset spring assembly 17 and the second reset spring assembly 22 both include a guide rod and a reset spring sleeved on the guide rod;

[0047] The reciprocating kneading mechanism includes a half-tooth shaft 18 and a tail shaft 19 rotatably connected to the compression frame 4. A third bevel gear is installed on both the half-tooth shaft 18 and the sliding shaft 5. The two third bevel gears mesh with each other. Two second half-tooth gears 20 are installed on the half-tooth shaft 18. Two kneading tooth plates 21 are installed on the kneading frame 6. The two kneading tooth plates 21 are respectively connected to the two second half-tooth gears 20. A set of second return spring assemblies 22 is installed between the kneading frame 6 and the compression frame 4. A fourth bevel gear is installed on the tail shaft 19. The fourth bevel gear is connected to the third bevel gear on the half-tooth shaft 18. A second connecting groove with a tail end opening and sliding connection with the tail shaft 19 is fixedly opened inside the kneading shaft 7.

[0048] The cross-sections of the first connecting groove, the second connecting groove, the tail shaft 19, and the fixed transmission shaft 11 are all regular hexagons, with the tail shaft 19 being set perpendicular to the fixed transmission shaft 11.

[0049] The cross-sections of the first connecting groove, the second connecting groove, the tail shaft 19, and the fixed transmission shaft 11 are all regular hexagons, and the tail shaft 19 is set perpendicular to the fixed transmission shaft 11. This structural design ensures the stability and accuracy of power transmission.

[0050] When the fixed transmission shaft 11 rotates, it can stably drive the sliding shaft 5 to rotate through the first hexagonal groove. During the rotation of the sliding shaft 5, it can stably transmit power to the kneading shaft 7 through the second hexagonal groove and the tail shaft 19.

[0051] During equipment operation, this structure will not slip, ensuring the coordinated movement of all components. It solves the problems of power loss and asynchronous movement of components that are prone to occur in traditional power transmission structures during transmission.

[0052] An active toothed roller 8 is mounted on the kneading shaft 7, and a driven toothed roller 9 is rotatably mounted on the frame 1. A kneading gap is provided between the active toothed roller 8 and the driven toothed roller 9. A rotary cutting disc 10 for rotary cutting corrugated cardboard is rotatably mounted on the frame 1. The output shaft end of the servo motor 3 is connected to the rotary cutting disc 10 via a first belt.

[0053] Both the driving toothed roller 8 and the driven toothed roller 9 are equipped with a set of V-shaped meshing racks 23 arranged in a circumferential array, and the surface of the V-shaped meshing racks 23 is evenly covered with friction patterns.

[0054] When the rubbing shaft 7 drives the active toothed roller 8 to rotate, the V-shaped meshing racks 23 arranged in a circumferential array on the active toothed roller 8 cooperate with the V-shaped meshing racks 23 on the driven toothed roller 9 to rub the corrugated cardboard waste at the rubbing gap and achieve segmented cutting of the corrugated cardboard waste.

[0055] The friction texture evenly distributed on the surface of the V-shaped meshing toothed rack 23 increases the friction between it and the waste material, resulting in a better kneading effect. This effectively solves the problem of insufficient kneading force and inadequate kneading of waste material in existing edge trimming machines. Compared with existing technologies, this solution can more efficiently crush and knead corrugated cardboard waste, improving the recycling effect of waste material.

[0056] When processing the same amount of corrugated cardboard waste, the edge trimmer with this structure can crush the waste into smaller pieces, which can be processed more quickly in the subsequent crushing and reprocessing process, shortening the overall waste processing time.

[0057] An electric heating plate 24 is fixedly installed on the frame 1. Both the driving toothed roller 8 and the driven toothed roller 9 have built-in electric heating rods. The heating temperature of the electric heating plate 24 and the electric heating rods is 90℃.

[0058] The heating plate 24 and the heating rod are electrically connected to the thermostat to maintain a constant heating temperature.

[0059] The heating plate 24 on the frame 1 and the heating rods built into the drive toothed roller 8 and driven toothed roller 9 can soften the adhesive and other sticky substances on the corrugated cardboard waste and make the corrugated cardboard waste brittle when heated to 90°C.

[0060] When the active toothed roller 8 and the driven toothed roller 9 rub the waste material, the softened glue is more easily separated, and the adhesion between the waste materials is improved.

[0061] This solves the problem in existing technologies where corrugated cardboard waste is difficult to separate due to sticky substances such as glue, leading to high recycling difficulty. Compared with existing technologies, this solution reduces the difficulty of waste recycling and improves recycling efficiency.

[0062] When recycling corrugated cardboard waste to make new cardboard, the waste, after being heated, has a more uniform glue distribution during the repressing process, resulting in more stable quality of the new cardboard and a reduction in the defect rate by about 20%.

[0063] The specific steps for using this utility model are as follows:

[0064] When the servo motor 3 starts, its output shaft drives the belt shaft 12 to rotate. The first bevel gear on the belt shaft 12 meshes with the first bevel gear on the fixed transmission shaft 11, causing the fixed transmission shaft 11 to rotate. The rotation of the fixed transmission shaft 11 drives the sliding shaft 5 to rotate through the first connecting groove inside the sliding shaft 5, providing power for the subsequent kneading mechanism. On the other hand, the second bevel gear on the fixed transmission shaft 11 drives the left gear shaft 13 to rotate. The left gear shaft 13 drives the right gear shaft 14 through the third belt. The first half gear 15 on the right gear shaft 14 cooperates with the compression tooth plate 16 on the compression frame 4, causing the compression frame 4 to move back and forth on the frame 1. The first reset spring assembly 17 plays a buffering and reset role, thereby using the compression force between the active tooth roller 8 and the driven tooth roller 9 to compress the loose corrugated cardboard waste before crushing, reducing the waste volume.

[0065] The rotation of the sliding shaft 5 drives the half-tooth shaft 18 installed on the compression frame 4 to rotate. The third bevel gear on the half-tooth shaft 18 meshes with the third bevel gear on the sliding shaft 5. When the half-tooth shaft 18 rotates, the two second half-tooth gears 20 installed on it are respectively connected to the two kneading tooth plates 21 on the kneading frame 6, so that the kneading frame 6 moves back and forth on the compression frame 4. The second return spring assembly 22 plays the role of buffering and resetting the kneading frame 6. At the same time, the rotation of the sliding shaft 5 drives the kneading shaft 7 to rotate through the tail shaft 19 and the second connecting groove inside the kneading shaft 7, so that the active toothed roller 8 moves back and forth relative to the driven toothed roller 9 and fully kneads the waste material, kneads and separates the glue and other substances on the surface of the waste material, improves the quality of waste recycling and reuse, and can also make the corrugated paper strips cut off thinner and segmented, improving the crushing effect.

[0066] When the kneading shaft 7 drives the active toothed roller 8 to rotate, the V-shaped meshing racks 23 arranged in a circumferential array on the active toothed roller 8 cooperate with the V-shaped meshing racks 23 on the driven toothed roller 9 to knead the corrugated cardboard waste at the kneading gap and achieve segmented cutting. The friction texture on the surface of the V-shaped meshing racks 23 increases the friction between the waste and the waste, improving the kneading effect.

[0067] In addition, when the heating plate 24 on the frame 1 and the heating rods built into the drive toothed roller 8 and driven toothed roller 9 are heated to 90°C, they can soften the adhesive and other sticky substances on the corrugated cardboard waste and make the waste brittle. When the drive toothed roller 8 and driven toothed roller 9 rub the waste, the softened adhesive is easier to separate, improving the adhesion between waste materials, reducing the difficulty of waste recycling and improving recycling efficiency. Moreover, when the cardboard is repressed to make new cardboard, the adhesive is more evenly distributed and the quality of the new cardboard is more stable.

[0068] After the servo motor 3 is started, the corrugated cardboard to be trimmed is conveyed forward at a set speed, and the rotary cutting disc 10 rotates at high speed to cut the corrugated cardboard waste.

[0069] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
