Description

Technical Field

[0001] The present invention belongs to the technical field of carton shredding devices, and more specifically, particularly relates to a shredding device for recycling and reusing waste carton. Background Art

[0002] In today's era of increasing awareness of resource recycling and environmental protection, the recycling and reuse of waste cartons has received more and more attention. As a common recyclable material, waste cartons can be efficiently processed and converted into renewable resources, which has significant economic and environmental benefits. However, the existing waste carton recycling and reuse crushing devices have many problems that need to be solved in practical applications.

[0003] First, when recycling waste cartons, they are often mixed with various foreign objects such as metal and plastic. The current shredding device lacks an efficient foreign object removal mechanism before processing. In most cases, the machine needs to be stopped to manually handle foreign objects, which not only seriously affects the continuity of shredding work, reduces production efficiency, but also increases labor costs.

[0004] Secondly, the existing foreign matter removal methods are not effective. Simple vibration or screening methods cannot fully loosen the multi-layer structure of waste cartons, making it difficult to effectively shake off the metal and plastic particles inside. This makes it very easy for the blades to be stuck by these remaining foreign matter during the subsequent crushing process, which not only damages the blades, but also frequently interrupts the crushing process, greatly reducing the crushing efficiency and increasing the cost of equipment maintenance and blade replacement.

[0005] Furthermore, the existing devices lack adaptability to foreign objects of different sizes. Larger particles are often difficult to be discharged from waste cartons by conventional means, resulting in residual foreign objects, affecting the quality of the waste cartons after crushing, and further reducing the purity and utilization value of recycled resources.

[0006] In addition, the existing shredding devices are insufficient in deeply cleaning foreign matter inside waste cartons. The device structure design is unreasonable, and foreign matter cannot be effectively discharged from deep inside the cartons, resulting in incomplete removal of foreign matter, which also affects the shredding quality and recycling effect. Summary of the invention

[0010] Preferably, each of the threaded rods passes through the outside of the side slide and cooperates with the side slide through a thread, the first bar-shaped tooth is located below the second bar-shaped tooth and is laterally placed on the left and right sides of the waste feed pipe, an inner slide rail is provided below the second bar-shaped tooth, and two cross slides are provided below the second bar-shaped tooth, the top of each cross slide is slidably installed in the inner slide rail, the side walls of the two first bar-shaped teeth are fixedly installed with a fixing plate, the fixing plate is fixedly connected to the first insertion rod on the side of the first bar-shaped tooth, and a fixing block is fixedly installed between every two insertion rods.

[0011] Preferably, a side groove is provided on the back of each of the insertion rods and the bending rod, a rotating shaft assembly is installed between each of the bending rods and the insertion rod, a blocking rod for limiting the rotation of the bending rod is fixedly installed on the side wall of each of the insertion rods, and a plurality of insertion rods tend to expand outward from top to bottom, a connecting rope is fixedly installed on the side wall of each of the bending rods, and the connecting rope extends into the side groove of the insertion rod and laterally penetrates the interior of the insertion rod, and at least two fixed rods are fixedly installed under each of the cross-sliding frames, and the end of each connecting rope is fixedly connected to the fixed rod.

[0012] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, the waste cardboard boxes above are driven to move forward by the rotation of multiple transmission wheels. At the same time, multiple groups of third motors are operated to drive the cams to rotate. The rotation of multiple cams drives the vibration plates to vibrate. The vibration of the vibration plates is transmitted to the waste cardboard boxes. When the waste cardboard boxes are vibrated, the multiple layers become loose, and the metal, plastic and other particles inside the waste cardboard boxes slide downward due to the vibration. Foreign objects inside the waste cardboard boxes can be removed without stopping the machine.

[0013] In the present invention, the cam strikes the waste cardboard box upward at a certain frequency, generating an instantaneous impact force that can vibrate foreign objects inside the waste cardboard box, thereby causing them to loosen. The cam and the striking assembly are used to perform double vibrations on the waste cardboard box, so that metal, plastic and other particles inside the waste cardboard box can be vibrated and fall, effectively preventing the problem of blade jamming when the waste cardboard box is subsequently crushed, thereby improving the efficiency of the waste cardboard box crushing. Since the feed port of the waste material feeding pipe is downward, the fallen metal and plastic particles will be discharged downward through the feed port.

[0014] In the present invention, two first motors drive the side slides to move inwards through threaded rods, and the two side slides move inwards to drive the side clamping plates to move inwards through the side clamping rods, and the two side clamping plates move inwards to squeeze the waste cardboard box on both sides. At this time, an opening occurs in the middle of the waste cardboard box, and metal and plastic particles inside the waste cardboard box are easier to fall out, and can help larger particles to fall out, further improving the discharge of foreign matter.

[0015] In the present invention, the first gear can drive the first bar-shaped tooth to move a greater distance, and the movement of the first bar-shaped tooth drives the movement of multiple insertion rods and bending rods on the side, and the multiple insertion rods and bending rods move into the waste cardboard box. A large gear ratio is used to drive a small gear ratio, thereby increasing the depth of the insertion rods and bending rods into the waste cardboard box, and further improving the ability to discharge foreign matter inside the waste cardboard box.

[0016] In the present invention, two first bar-shaped teeth drive multiple insertion rods and bending rods to move through a fixed plate and multiple fixed blocks. The insertion rods and the bending rods move forward and are inserted into the waste cardboard box. The side walls of the bending rods are connected with connecting ropes, and the connecting ropes are fixed by the fixed rods under the transverse sliding frame. Therefore, when the insertion rods and the bending rods move a certain distance, the bending rods are pulled by the connecting ropes to rotate. When the first bar-shaped teeth are subsequently reset, the bent bending rods can further pull out the particles inside the waste cardboard box. After the movement and reset, the bending rods are restored. By designing the insertion rods to be bendable, the particles inside the waste cardboard box can be further pulled out.

At least two striking components 21 are fixedly installed at the bottom of the waste feed pipe 1 below the impact hole 16 (the striking component is provided with an electromagnetic, a spring, and an output rod. When the striking component 21 is powered on, the electromagnetic presses the output rod downward and the spring is compressed. When the striking component 21 is powered off, the spring drives the output rod to move upward quickly. , forming a striking state), the output end of each striking component 21 is located in the impact hole 16, the end of each side clamping rod 26 is fixedly installed with a side clamping disc 5, and each side clamping disc 5 is located inside the waste feeding pipe 1, and is located on the left and right sides above the vibration plate 15, and the first motors 13 on both sides of the waste feeding pipe 1 are started, and the two first motors 13 drive the side slides 25 to move inward through the threaded rods 14, and the two side slides 25 move inward and drive the side clamping discs 5 to move inward through the side clamping rods 26, and the two side clamping discs 5 move inward to squeeze the waste carton on both sides.

The gear ratio of the two first gears 27 is smaller than that of the second gear 28. Therefore, the first gear 27 rotates more circles than the second gear 28. The first gear 27 can drive the first bar tooth 29 to move a greater distance. The movement of the first bar tooth 29 drives the multiple insertion rods 34 and the bending rods 39 on the side to move. The multiple insertion rods 34 and the bending rods 39 move into the waste carton. The large gear ratio drives the small gear ratio, thereby increasing the depth of the insertion of the insertion rods 34 and the bending rods 39 into the waste carton, further improving the ability to discharge foreign matter inside the waste carton.

[0023] A side groove 35 is provided on the back of each insertion rod 34 and bending rod 39, a rotating shaft assembly 37 is installed between each bending rod 39 and the insertion rod 34, and a stopper rod 38 for limiting the rotation of the bending rod 39 is fixedly installed on the side wall of each insertion rod 34. A plurality of insertion rods 34 tend to expand outward from top to bottom, and a connecting rope 36 is fixedly installed on the side wall of each bending rod 39.

At least two fixed rods 33 are fixedly installed under each horizontal sliding frame 32, and the end of each connecting rope 36 is fixedly connected to the fixed rod 33.

[0024] Working principle: Put the waste cartons to be recycled into the waste feeding pipe 1 from the feeding port, and the waste cartons enter the waste feeding pipe 1. The multiple second motors 19 under the vibration plate 15 are started to drive the multiple conveying wheels 2 to rotate. The rotation of the multiple conveying wheels 2 drives the waste cartons above to move forward. At the same time, the multiple third motors 23 are operated to drive the cams 24 to rotate. The rotation of the multiple cams 24 drives the vibration plate 15 to vibrate. The vibration of the vibration plate 15 is transmitted to the waste cartons. When the waste cartons are vibrated, the layers become loose, and the metal, plastic and other particles inside the waste cartons are vibrated and slide downward. Foreign matter inside the waste cartons can be removed without stopping the machine. When the vibration plate 15 vibrates, the multiple striking components 21 operate, the output ends of the multiple striking components 21 quickly extend upward, and quickly hit the bottom of the waste carton, and the cam 24 hits the waste carton upward at a certain frequency, generating an instantaneous impact force that can vibrate the foreign matter inside the waste carton, thereby loosening it. The cam 24 and the striking component 21 are used to perform a double vibration on the waste carton, so that the metal, plastic and other particles inside the waste carton can be vibrated and fall, effectively preventing the blade from getting stuck when the waste carton is subsequently crushed, and improving the efficiency of crushing the waste carton. Since the feed port of the waste material feeding pipe 1 is downward, the fallen metal and plastic particles will be discharged downward through the feed port; When the waste paper box moves forward on the vibration plate 15, the first motors 13 on both sides of the waste material feeding pipe 1 are started, and the two first motors 13 drive the side slides 25 to move inward through the threaded rods 14. The two side slides 25 move inward and drive the side clamping plates 5 to move inward through the side clamping rods 26. The two side clamping plates 5 move inward to squeeze the waste paper box on both sides. At this time, an opening occurs in the middle of the waste paper box, and the metal and plastic particles inside the waste paper box are easier to fall out, and can help larger particles to fall out, further improving the discharge of foreign matter; The movement of the two side slides 25 drives the two second gears 28 to move. The two second gears 28 move on the side of the second strip-shaped teeth 3 and rotate. The rotation of the two second gears 28 drives the first gear 27 to rotate. The rotation of the first gear 27 drives the first strip-shaped teeth 29 to move horizontally. The gear ratio of the two first gears 27 is smaller than that of the second gear 28. Therefore, the first gear 27 rotates more circles than the second gear 28. The first gear 27 can drive the first strip-shaped teeth 29 to move a greater distance. The movement of the first strip-shaped teeth 29 drives the multiple insertion rods 34 and the bending rods 39 on the side to move. The multiple insertion rods 34 and the bending rods 39 move into the waste carton. The large gear ratio drives the small gear ratio, thereby increasing the depth of the insertion of the insertion rods 34 and the bending rods 39 into the waste carton, further improving the ability to discharge foreign matter inside the waste carton. In the initial state, both side walls of the waste feeding pipe 1 are provided with grooves, and the multiple insertion rods 34 and bending rods 39 on both sides are located in the grooves. When the first bar-shaped teeth 29 move, the two first bar-shaped teeth 29 drive the multiple insertion rods 34 and bending rods 39 to move through the fixing plate 4 and the multiple fixing blocks 41, and the insertion rods 34 and bending rods 39 move forward and are inserted into the waste paper box. The side walls of the bending rods 39 are connected with connecting ropes 36, and the connecting ropes 36 are fixed by the fixing rods 33 under the horizontal sliding frame 32. Therefore, when the insertion rods 34 and the bending rods 39 move a certain distance, the bending rods 39 are pulled by the connecting ropes 36 to rotate. When the first bar-shaped teeth 29 are reset later, the bent bending rods 39 can further pull out the particles inside the waste paper box, and after the movement and reset, the bending rods 39 are restored. By designing the insertion rods 34 to be bendable, the particles inside the waste paper box can be further pulled out. When the side slide 25 moves, it drives the first strip-shaped teeth 29 to move, and the plurality of insertion rods 34 and bending rods 39 drive the cross slide 32 to move, and the cross slide 32 slides under the second strip-shaped teeth 3; After the foreign matter inside the waste cardboard box is discharged, the multiple conveying wheels 2 continue to drive the cardboard box to move forward, and the waste cardboard box enters the crushing assembly 11 and is cut and crushed.
