Description

Technical Field

[0001] This utility model relates to the technical field of roll material recycling equipment, specifically to an automatic crushing and recycling device for roll material scraps. Background Technology

[0002] In modern industrial production, metal coils are widely used in construction, automotive, electronics, packaging, and many other fields. However, the processing and use of metal coils inevitably generates a large amount of scrap and waste. If these scraps are not properly handled, they will not only cause serious waste of resources but also have adverse effects on the environment. According to relevant statistics, the generation rate of scrap and waste in the processing of metal coils can typically reach 10% to 30%, and this amount is becoming increasingly substantial as industrial production scales up.

[0003] Traditional methods for handling rolled metal scrap have many shortcomings. On the one hand, some companies use manual cutting and crushing, which is not only inefficient and costly in terms of labor, but also makes it difficult to guarantee the precision of cutting and crushing, failing to meet the requirements for subsequent recycling. On the other hand, some existing crushing and recycling devices have structural design deficiencies, such as unstable material feeding, which can easily lead to deviation and jamming of rolled metal scrap during the feeding process, affecting the normal crushing and recycling process; the crushed metal rolled metal has an inconsistent particle size and lacks a grading and screening structure, resulting in low subsequent processing efficiency. Utility Model Content

[0004] Based on the above description, this utility model provides an automatic crushing and recycling device for rolled metal scraps to solve the shortcomings of existing metal rolled metal crushing and recycling equipment, such as low working efficiency, poor cutting and crushing accuracy, and lack of screening structure, which leads to the mixing of metal fragments of different particle sizes, affecting subsequent recycling and processing.

[0005] This utility model is achieved through the following technical solution: An automatic crushing and recycling device for rolled material waste includes a box body. The top surface of the box body is provided with a feeding port. The feeding port is provided with a material guiding component that is in close contact with the surface of the rolled material. Inside the box body, a cutting component, a crushing component, and a sorting component are arranged sequentially from top to bottom. A partition plate is also provided between the cutting component and the crushing component. The partition plate is arranged in a bucket shape and has a through hole at the center of the bottom surface. A vacuum conveyor is also provided on one side of the box body. The feeding pipe of the vacuum conveyor extends to the bottom of the box body, and the other end of the vacuum conveyor is connected to a storage box.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the material guiding assembly includes a fixed frame, a material guiding roller, and a drive motor. The fixed frame is arranged in a rectangular structure. Multiple material guiding rollers are provided and rotatably installed inside the fixed frame, and the multiple material guiding rollers are connected by transmission. The drive motor is fixedly installed on one side of the fixed frame and is connected by transmission to one of the material guiding rollers.

[0008] Furthermore, the material guiding assembly is provided in two sets and arranged opposite to each other. The inner side wall of the box is also provided with a sliding groove. The side wall of the fixing frame is provided with a flange and is slidably inserted into the sliding groove. The outer side wall of the box is also provided with an electric telescopic rod. The output end of the electric telescopic rod extends horizontally inward and is fixedly connected to the side of the fixing frame away from the center of the box.

[0009] Furthermore, the cutting assembly includes two cutting shafts disposed below the material guiding assembly, and the two cutting shafts are arranged at intervals and multiple disc blades are fixedly installed on the outer side wall. The multiple disc blades are arranged perpendicular to the surface of the roll material. A hydraulic shear is also provided below the cutting shafts, and the cutting edge of the hydraulic shear extends towards the center of the box and completely covers the roll material.

[0010] Furthermore, the crushing assembly includes two spaced-apart crushing rollers, which are positioned directly below the through holes of the partition plate. The two crushing rollers are connected by a gear structure. A drive motor is also provided on the outer wall of the housing and is connected to one of the crushing rollers.

[0011] Furthermore, the sorting component includes a screen plate inside the box and a number of slots on the inner side wall of the box. Multiple screen plates are correspondingly arranged and sequentially inserted into the slots for locking and fixing. The multiple screen plates are all inclined downwards and arranged in an alternating manner.

[0012] Furthermore, an annular groove is provided through the frame of the screen plate and filled with vibration damping pads, the vibration damping pads being rubber pads, and a vibration motor is also provided on the bottom surface of the screen plate.

[0013] Furthermore, the mesh diameter of the multiple screen plates gradually decreases from top to bottom, and each screen plate has a discharge port arranged on one side of its end.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: This application improves upon existing coil recycling equipment by employing a roller-guided conveyor system. This not only ensures continuous and stable transport of the metal coil, effectively preventing deviation and jamming, but also allows for fixed-length cutting using a cutting assembly, initially reducing the coil into smaller fragments for subsequent crushing. This significantly reduces crushing difficulty and energy consumption, while improving the uniformity of particle size. Furthermore, this application utilizes a grading and screening method to classify and discharge the crushed metal fragments. Finer metal powder can be used for powder metallurgy or high-end alloy production, while larger fragments can be directly recycled, reducing burn-off during the melting process. After grading, the fragments can be utilized according to their characteristics, avoiding the problems of "using large materials for small purposes" or "mixed processing leading to reduced value."

Detailed Implementation

[0016] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0018] Combination Figure 1-6 As shown, an automatic crushing and recycling device for rolled material waste includes: The box 1 is the main structure of the entire recycling equipment. It is rectangular and has a feed inlet 11 at the top. Multiple discharge outlets 12 are provided on its side walls to discharge the crushed metal fragments. The material guiding component 2 is located inside the housing 1 and near the feed inlet 11. It is used to level the metal coil so that the coil can be continuously conveyed vertically downward so that subsequent equipment can cut and crush it. The cutting component 3 is located below the material guiding component 2 and is used to cut the leveled metal coil into fragments of a specified length. The crushing component 6 is located below the cutting component 3 and is used to further crush the pre-cut metal coil into smaller particles for subsequent recycling. The sorting component 4 is located below the crushing component 6. It sorts and recycles metal fragments of different particle sizes by screening, so as to make them more suitable for use according to their characteristics and improve their utilization value. Vacuum conveyor 5, preferably Yuebang pneumatic vacuum feeder QVC-2, is set on one side of box 1 and connected to the bottom of box 1. It uses vacuum pumping to extract some metal powder and small fragments so that they can be transferred to storage box for recycling by other equipment.

[0019] Specifically, in this embodiment, the material guiding assembly 2 includes a fixed frame 21, a material guiding roller 22, and a drive motor 23. Two fixed frames 21 are provided and arranged opposite to each other. A sliding groove is provided on the inner side wall of the box body 1. The fixed frame 21 is slidably assembled with the inner wall of the box body 1 through the flange on the side wall surface, and the two fixed frames 21 are oriented towards the center.

[0020] Multiple guide rollers 22 are provided and are rotatably mounted on the fixed frame 21. The multiple guide rollers 22 located on the same fixed frame 21 should be connected by a transmission structure of belt and pulley, or chain and sprocket. At the same time, the drive motor 23 is set on the fixed frame 21 and is used to drive one of the guide rollers 22, thereby driving all the guide tubes to rotate in a specific direction.

[0021] Furthermore, in the above structure, the guide rollers 22 on the two fixed frames 21 should be arranged alternately, or they can be arranged symmetrically. Figure 2 and Figure 3The arrangement shown is symmetrical. In the staggered arrangement, the deformation of the roll material can be eliminated by using the alternating bending stress generated by the asymmetrical roller system, so that the roll material after being input into the box 1 is long and straight and is conveyed vertically downward.

[0022] Considering the diverse thicknesses of roll materials during actual use, to enhance the applicability of the entire recycling equipment, an electric telescopic rod 24 should be installed on the outer wall of the housing 1. This electric telescopic rod 24 is preferably YBK-6D, with its output end extending into the housing 1 and fixedly connected to the back of the fixed frame 21. This allows for the adjustment of the distance between the two sets of material guiding components 2 by the telescopic adjustment of the two electric telescopic rods 24, thereby adapting to roll materials of different thicknesses, ensuring the leveling effect and the continuity of conveying during the conveying process.

[0023] The cutting assembly 3 includes two cutting shafts 31 located below the material guide assembly 2. Multiple disc cutters 32 are fixedly mounted on the cutting shafts 31, and the spacing between the multiple disc cutters 32 is adjusted according to actual needs to ensure that the roll material can be vertically cut into multiple thin metal strips.

[0024] Furthermore, the two cutting shafts 31 should be driven by gears so that they rotate relative to each other, and one of the cutting shafts 31 should be equipped with a motor to drive it to rotate.

[0025] In addition, since the long strip of metal will cause pulling during the subsequent crushing process, a hydraulic shear 33 should be arranged below the cutting shaft 31. The hydraulic shear 33 can be a QC11Y series, such as QC11Y-6x3200 (maximum cutting thickness of 6mm, cutting length of 3200mm), or a gantry shear, such as QC11Y-1500 gantry shear (can cut plates with a thickness between 30 and 120mm, cutting length of 1500mm).

[0026] Therefore, as the vertically conveyed strips of metal continue to be conveyed downwards, they are cut to a fixed length by the cutting equipment. Through the cooperation between the hydraulic shears 33 and the disc cutter 32, the metal coil is initially cut into metal fragments of a specified size to facilitate further crushing in the future.

[0027] In addition, since the metal fragments will fall downwards after cutting, but some lighter metal fragments are very easy to scatter in all directions, a funnel-shaped divider 34 should also be installed below the cutting assembly 3. This divider 34 should be designed as follows: Figure 5 As shown, the inclined sidewalls guide the metal sheets towards the center for further crushing.

[0028] The crushing assembly 6 includes two spaced-apart crushing rollers positioned directly below the through-hole of the partition plate 34. The two crushing rollers are selected according to the material, hardness, thickness, and particle size requirements of the material being crushed. For example, toothed rollers are used for crushing high-hardness steel (such as carbon steel and alloy steel) with a thickness of 2-10mm. The size of the crushed metal particles can be controlled by adjusting the tooth spacing and rotation speed. The two crushing rollers can also mesh with each other using the same gear transmission structure as the guide roller 22. One of the crushing rollers is equipped with a motor to drive its rotation. (See attached drawing for details.) Figure 4 The guide roller 22 in the transmission structure.

[0029] The sorting component 4 includes multiple inclined downward screen plates 41 arranged in an alternating pattern. The screen plate 41 is also provided with annular grooves on its frame and is filled with vibration damping pads 42. The vibration damping pads 42 can be supported by elastic materials such as rubber or silicone and separate the screen part in the center from the frame part.

[0030] Meanwhile, a slot 43 is provided on the inner wall of the box 1. The slot 43 extends outward to form a rectangular opening. The staff can insert the screen plate 41 into the box 1 by sliding and plugging it in, and then lock it in place with bolts.

[0031] In addition, reinforcing ribs are provided on the bottom surface of the screen, and a vibration motor 44 is equipped on the reinforcing ribs. The vibration motor 44 in the attached figure is relatively large, mainly for ease of display. Its actual volume should be smaller than the reinforcing ribs to avoid metal fragments from accumulating on its surface. The vibration motor 44 is preferably YZS-3-4 from the YZS series and is equipped with a separate battery for power supply. The vibration motor 44 is mainly used to improve the screening effect of metal fragments and prevent metal fragments from accumulating on its surface. Moreover, the vibration can be blocked by the vibration isolation pad 42, thereby reducing its vibration transmission effect and preventing its vibration from affecting the normal operation of other components.

[0032] In addition, among the aforementioned multiple screen plates 41, the mesh diameter should gradually decrease from top to bottom, and its ends should be close to the discharge port 12 on the side wall of the box 1. This allows for the classification and recycling of metal fragments of different sizes through vibration. Larger fragments can be directly returned to the furnace for smelting, reducing burn-off during the melting process. After classification, the fragments can be utilized according to their characteristics, avoiding the problems of "using large materials for small purposes" or "mixing them to reduce their value."

[0033] The drive motor 23, vibration motor 44, electric telescopic rod 24, and hydraulic shear 33 should all be connected to an external control console via wires or Bluetooth modules for remote control and programming, so as to achieve automated continuous crushing and recycling, thereby improving the production efficiency of the entire recycling device. Moreover, with the help of automated production, the amount of labor can be effectively reduced and labor costs can be saved.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the technical solutions of the embodiments of this utility model.
