Description

Technical Field

[0001] The present application relates to the technical field of recycling and crushing of metal parts, and specifically discloses a recycling and crushing device for metal parts. Background Art

[0002] Metal parts, also known as metal parts, refer to metal blocks, metal bars and metal tubes of various specifications and shapes made of metal materials;

[0003] In the field of electronic components, most metal parts are actually gold-plated metal parts, that is, they are made of base metal, but in order to ensure the performance of the parts, gold is usually plated on the surface of such parts, using the characteristics of gold elements to ensure certain characteristics of the parts;

[0004] As parts are used, they will naturally wear out and expire. Such metal parts need to be recycled because they are usually plated with precious metals. The gold and silver on the surface of the parts are removed through the de-gold process. The core of the de-gold process is aqua regia. When using aqua regia, the smaller the material itself, the better, because it can react better with aqua regia. Therefore, after the metal parts are recycled, they need to be crushed;

[0005] China Publication No. CN216025176U discloses a metal parts processing waste crushing and recycling device, including a box, a recycling mechanism and a driving mechanism, the bottom of the box is slidably connected with a collection frame, the upper end of the box is horizontally fixedly connected with a workbench, two opposite side walls of the workbench are provided with an opening, the lower end of the opening is fixedly connected with a guide plate for guiding the waste, a crushing roller for crushing the waste is arranged just below the output end of the guide plate, and the crushing roller is fixedly installed on the inner wall of the box. The utility model uses a belt to drive the magnet to move, so as to use the magnetic force of the magnet to pull the waste on the upper end of the workbench into the opening, thereby completing the collection of the waste and improving the collection efficiency of the waste;

[0006] Currently, most of the metal processing waste crushing devices have technical improvements to improve the crushing effect. However, there are still some shortcomings: for some highly ductile metal parts, the crushing effect is poor. For example, the inner layer is base metal copper and the outer layer is gold-plated. The use of crushing rollers or similar crushing devices cannot produce significant crushing effects. In view of this, the inventor proposes a recycling crushing device for metal parts. Summary of the invention

[0007] The purpose of the present invention is to solve the problem that the conventional metal parts recycling and crushing device has poor crushing effect on high-ductility metal parts.

[0008] In order to achieve the above object, the present invention provides the following basic scheme:

[0009] A recycling and crushing device for metal parts, comprising a feed assembly arranged in sequence from top to bottom, a rolling and deformation assembly connected to the feed assembly, a shell connected to the rolling and deformation assembly, a cutting and crushing assembly arranged inside the shell, and a discharging assembly arranged at the bottom of the shell;

[0010] The rolling deformation assembly includes a frame, a connecting pipe arranged at the bottom of the frame and connected to the shell, a double rolling roller arranged inside the frame, and a motor arranged outside the frame and connected to the double rolling rollers;

[0011] The double rolling rollers rotate in opposite directions, and the distance between the double rolling rollers and the inner wall of the frame gradually decreases along the rotation direction of the double rolling rollers;

[0012] Cutting and crushing assembly: includes a motor arranged at the bottom of the shell, a rotating rod coaxially connected to the motor, a plurality of cutting knives arranged around the rotating rod, a plurality of connecting bearings sleeved on the rotating rod and a blocking ring installed on the outer ring of the connecting bearing. The cutting knives pass through between adjacent blocking rings and act on the metal parts to cut the metal parts.

[0013] The principles and effects of this basic solution are:

[0014] 1. Compared with the prior art, the device has a simple structure and an ingenious design. The device is a special crushing device for ductile metal parts, which solves the problem that the traditional metal part recycling crushing device has poor crushing effect on high-ductility metal parts. The core of the traditional crushing device is to directly destroy the structure of the metal part and change the shape. The core of the device is: preferentially stretching and deforming the metal part, and reasonably utilizing the high ductility of the metal part. After the metal part is stretched and deformed, the metal part becomes thinner and longer, and the metal part is cut by a cutting knife. After cutting, the metal part naturally changes from a large volume to a small volume, thereby completing the crushing action.

[0015] 2. Compared with the prior art, the present device is provided with a rolling deformation component. The rolling deformation component in the present device still uses double rolling rollers. However, for the double rolling rollers, a dual output power source is used so that the driving directions of the double rolling rollers are opposite. By the opposite driving directions of the double rolling rollers, the metal parts can be rolled and deformed with the rolling deformation component, thereby making the metal parts thinner and longer.

[0016] 3. Compared with the prior art, the thinned and elongated metal parts are acted upon by the cutting knife after a series of movements. The cutting knife can better act on the thinned and elongated metal parts, making the metal parts into more and more small parts. These small, long and thin metal parts will have a better effect on the subsequent demetallization process and will have more sufficient contact with aqua regia.

[0017] 4. Compared with the prior art, the device is provided with multiple cutting edges on the cutting knife. The setting of multiple cutting edges can make the thinned and elongated metal parts be cut into multiple small metal parts. This design can obtain more metal parts, thereby making the volume of the metal parts to be stripped smaller.

[0018] Furthermore, the feed assembly includes a feed bin, an end cover disposed on the top of the feed bin and detachably connected to the feed bin, and a connecting bin connected to the feed bin, wherein the connecting bin is connected to the frame.

[0036] Implementation example Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown:

[0037] A recycling and crushing device for metal parts includes a feed assembly, a rolling deformation assembly connected to the feed assembly, a shell 1 connected to the rolling deformation assembly, a cutting and crushing assembly arranged inside the shell 1, and a discharge assembly arranged at the bottom of the shell 1. A plurality of support columns 4 are arranged at the bottom of the shell 1, and rubber anti-slip pads are arranged at the free ends of the support columns 4. A cover plate 10 is arranged on the shell 1.

[0038] Discharge assembly: The discharge assembly includes a through thread groove 6 penetrating through the inner bottom of the shell 1, a collection pipe 2 arranged on the outer bottom of the shell 1 and threadedly connected to the through thread groove 6, and connection ports 3 symmetrically arranged on the collection pipe 2, one of the connection ports 3 is connected to the air outlet, and the other connection port 3 is connected to the collection bag.

[0039] Specifically: the blower blows the cut and crushed metal parts toward the collecting bag, thereby completing the collection of the metal parts in the collecting bag.

[0040] Feed assembly: The feed assembly includes a feed bin 13, an end cover 14 disposed on the top of the feed bin 13 and detachably connected to the feed bin 13, and a connecting bin 12 connected to the feed bin 13, wherein the connecting bin 12 is connected to the frame 16;

[0041] Specifically, the metal parts fall into the feed bin 13, and then enter the frame 16 through the connecting bin 12 to be crushed and deformed by the component;

[0042] The rolling deformation component includes a frame 16, a connecting pipe 22 arranged at the bottom of the frame 16 and connected to the shell 1, a double rolling roller 11 arranged inside the frame 16, and a motor 19 arranged outside the frame 16 and connected to the double rolling roller 11; the connecting pipe 22 is surrounded by inclined surfaces 31, and the inclination direction of the inclined surface 31 is toward the center of the connecting pipe 22.

[0043] The double laminating rollers 11 rotate in opposite directions, and the distance between the double laminating rollers 11 and the inner wall of the frame 16 gradually decreases along the rotation direction of the double laminating rollers 11;

[0044] Specifically: there is no meshing between the double laminating rollers 11 and no metal parts can pass through; a material guide plate is provided on the inner top of the frame 16; the distance between the double laminating rollers 11 and the inner wall of the frame 16 close to the material guide plate is a first gap 29; the distance between the double laminating rollers 11 and the inner wall of the frame 16 away from the material guide plate is a second gap 30; the first gap 29 gradually decreases along the direction of the second gap 30.

[0045] Specifically: the distance between the double laminating roller 11 and the inner wall of the frame 16 gradually decreases along the rotation direction of the double laminating roller 11, and a large gap is required for metal parts to enter. Then as the gap gradually decreases, the metal is extruded, and the volume of the extruded metal parts changes, becoming longer and thinner.

[0046] Since the double rolling rollers 11 rotate in opposite directions, the motor 19 needs to be designed independently, and since the extruded metal piece needs to be made longer and thinner, the speed of the motor 19 should not be too fast.

[0047] Therefore, the front and rear ends of the frame 16 are detachably connected with a front cover 17 and a rear cover 15, respectively. The rear cover 15 is a transparent protective cover, and the transparent protective cover is used to observe the operating status of the double rolling rollers 11. The front cover 17 is used to install the motor 19. The output shaft of the motor 19 is connected to a reducer 18. The reducer 18 is provided with a driving gear and two sets of driven gear sets 21 meshing with the driving gear. The gear diameter of the driven gear set 21 is larger than the gear diameter of the driving gear. The output end of the driven gear set 21 passes through the reducer 18 and is coaxially connected to the double rolling rollers 11.

[0048] The speed reduction and the opposite rotation of the double rolling rollers 11 are completed by the driven gear set 21. In terms of connection: the motor 19 is connected to the front cover 17 and a motor bracket 20 is provided. A plurality of connecting threaded holes 23 are provided on the front cover 17 and the rear cover 15. The front cover 17 and the rear cover 15 are threadedly mounted on the frame 16 through threaded connection.

[0049] The cutting and crushing assembly includes a motor 5 arranged at the bottom of the shell 1, a rotating rod 8 coaxially connected to the motor 5, a plurality of cutting knives 7 arranged around the rotating rod 8, a plurality of connecting bearings 27 sleeved on the rotating rod 8, and a blocking ring 25 installed on the outer ring of the connecting bearing 27. The cutting knives 7 pass through between adjacent blocking rings 25 to act on the metal parts to cut the metal parts.

[0050] Specific:

[0051] A material guiding surface 9 is provided on the rotating rod 8 away from the motor 5, and a rotating bearing 24 is provided at the connection between the material guiding surface 9 and the rotating rod 8, so that the rotating rod 8 moves and the material guiding surface 9 does not move. A plurality of connecting rods 28 are provided on the outer ring of the connecting bearing 27, and the connecting rods 28 are connected to the blocking ring 25. A plurality of blades 32 are provided at the free end of the cutting knife 7. The external dimensions of the material guiding surface 9 are equal to the external dimensions of the blocking ring 25. A contact plate 26 used in conjunction with the blade 32 is provided on the inner wall of the shell 1. The contact plate 26 can contact the blade of the blade 32 and the hardness of the contact plate 26 is greater than the hardness of the cutting knife 7.

[0052] Specific implementation process:

[0053] In the first step, the metal piece enters the feed assembly and then enters the housing 1, and the double rolling rollers 11 start to work, and the metal piece becomes longer and thinner;

[0054] In the second step, the metal piece that has become longer and thinner enters the cutting and crushing assembly because the connecting tube 22 has inclined surfaces 31 on all sides. Due to the action of the guide surface 9, the metal piece falls from both sides of the shell 1, and then the cutting knife 7 acts on the metal piece to complete the cutting of the metal piece. Since the free end of the cutting knife 7 is provided with a plurality of blade edges 32, the metal piece will be further crushed after the cutting is completed.

[0055] In the third step, finally, the metal parts enter the collection tube 2 through the threaded groove 6, thereby completing the collection of the cut and crushed metal parts.

[0056] The device solves the problem that the conventional recycling and crushing device for metal parts has poor crushing effect on metal parts with high ductility.

[0057] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
