Description

Technical Field

[0001] This application relates to the technical field of waste circuit board recycling and processing, and in particular to a crushing device for waste circuit board recycling. Background Technology

[0002] A circuit board is a fundamental component in electronic devices used to connect and support electronic components. It connects electronic components such as resistors, capacitors, and chips together through pre-designed conductive lines to form a complete circuit system.

[0003] To recycle waste circuit boards, they need to be crushed. Currently, the method involves feeding the circuit boards into a crushing chamber, where the crushing rollers only crush them once. This results in incomplete crushing, affecting subsequent recycling and requires improvement. Utility Model Content

[0004] The purpose of this application is to provide a crushing device for recycling waste circuit boards in order to improve the crushing effect of circuit boards.

[0005] The present application provides a crushing device for recycling waste circuit boards, which adopts the following technical solution: it includes a crushing box, a crushing container rotatably connected inside the crushing box, a first driving component connected to the crushing box for driving the crushing container to rotate, a feed pipe and a discharge pipe connected to the crushing box, a crushing chamber and a channel provided in the crushing container, the channel communicating with the crushing chamber, a crushing mechanism connected to the crushing container, and the discharge port of the feed pipe and the feed inlet of the discharge pipe both corresponding to the channel.

[0006] By adopting the above technical solution, the circuit board in the feed pipe moves through the channel to the crushing mechanism, which crushes the circuit board. The crushed circuit board falls to the bottom of the crushing chamber. The first driving component drives the crushing box to rotate, and the circuit board located at the bottom of the crushing chamber can pass through the crushing mechanism again. The crushing mechanism crushes the circuit board again. The waste circuit board is subjected to multi-stage crushing treatment, thereby improving the crushing effect of the circuit board and providing a guarantee for subsequent recycling.

[0007] Optionally, the crushing mechanism includes a plurality of crushing rollers rotatably connected in the crushing chamber and a drive assembly for driving all the crushing rollers to rotate. The drive assembly is connected to the crushing box, and the outer circumferential surface of the crushing rollers is provided with spiral blades.

[0008] By adopting the above technical solution, the crushing roller is set inside the crushing chamber and driven to rotate by the drive assembly, which can effectively crush waste circuit boards. The spiral blade is set on the outer circumference of the crushing roller, which further enhances the crushing effect, allowing the waste circuit boards to be crushed more thoroughly, thereby improving the efficiency and quality of subsequent recycling.

[0009] Optionally, two adjacent helical blades are arranged in an alternating pattern.

[0010] By adopting the above technical solution, the staggered arrangement of the spiral blades enables the crushing rollers to form a coordinated shearing action during rotation. This shearing action can more effectively cut and crush waste circuit boards, improving crushing efficiency and effect, ensuring that the circuit boards are completely pulverized, thus facilitating subsequent recycling.

[0011] Optionally, the drive assembly includes a gear connected to one end of each of the crushing rollers and a second drive member for driving one of the gears to rotate, the second drive member being connected to the crushing box, and adjacent gears meshing.

[0012] By adopting the above technical solution, the cooperation between the gear and the second drive component can realize the synchronous drive of multiple crushing rollers, ensure the coordinated work of the crushing rollers, reduce the drive, and increase the correlation of the overall structure.

[0013] Optionally, a partition plate is connected to the inner wall of the crushing chamber on the side away from the channel, and the crushing roller is located between the partition plate and the channel.

[0014] By adopting the above technical solution, the separator plate divides the broken circuit board into two parts, with the two parts of fragments located on opposite sides of the separator plate. When the crushing box rotates, one part of the fragments separates from the separator plate due to gravity and re-enters contact with the corresponding spiral blades, achieving further crushing. The other part of the fragments falls onto the separator plate due to gravity. When the separator plate is higher than the spiral blades, this part of the fragments contacts other spiral blades along the separator plate, achieving further crushing. This allows the fragments to contact multiple spiral blades, increasing the contact area and improving the crushing efficiency.

[0015] Optionally, several of the partition plates are spaced apart on one side of the inner wall of the channel.

[0016] By adopting the above technical solution, several partition plates can make the fragments come into contact with multiple spiral blades, increasing the contact area and improving the crushing efficiency.

[0017] Optionally, the feed pipe is connected to an extrusion assembly and a bearing assembly, with the bearing assembly located between the extrusion assembly and the crushing box.

[0018] By adopting the above technical solution, the extrusion assembly can initially extrude waste circuit boards, reducing their volume and thus improving subsequent crushing efficiency. The bearing assembly controls the feeding, ensuring that waste circuit boards enter the crushing chamber in batches and in an orderly manner, avoiding blockages and improving the stability of the device operation.

[0019] Optionally, the extrusion assembly includes two extrusion plates slidably connected within the feed pipe and a third driving member for driving the extrusion plates to slide toward the axis of the feed pipe, the third driving member being connected to the crushing box.

[0020] By adopting the above technical solution, the two extrusion plates can slide towards the axis of the feed tube under the drive of the third driving component, thereby pre-extruding the waste circuit boards. This pre-extrusion method can reduce the volume of the circuit boards, making them more compact and facilitating subsequent crushing.

[0021] Optionally, the bearing assembly includes a bearing plate slidably connected within the feed pipe and a fourth driving member for driving the bearing plate to slide. The fourth driving member is connected to the crushing box, and the bearing plate is used to control the opening and closing of the feed pipe.

[0022] By adopting the above technical solution, the support plate is slidably connected inside the feed pipe, and its sliding is driven by the fourth driving component, allowing for flexible control of the feed pipe's on / off state. This design enables the feeding of waste circuit boards to be paused or continued as needed during the crushing process, effectively avoiding the problem of insufficient crushing caused by excessive feeding.

[0023] Optionally, the extrusion plate is bonded to the support plate.

[0024] By adopting the above technical solution, the circuit board is reduced to be located between the extrusion plate and the carrier plate, thereby improving the extrusion effect of the circuit board.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The circuit board in the feed pipe moves through the channel to the crushing mechanism, which crushes the circuit board. The crushed circuit board falls to the bottom of the crushing chamber. The first drive unit drives the crushing box to rotate, and the circuit board at the bottom of the crushing chamber can pass through the crushing mechanism again. The crushing mechanism crushes the circuit board again. The waste circuit board is subjected to multi-stage crushing treatment, thereby improving the crushing effect of the circuit board and providing a guarantee for subsequent recycling.

[0027] 2. The staggered arrangement of the spiral blades allows the crushing rollers to create a coordinated shearing action during rotation. This shearing action can more effectively cut and crush waste circuit boards, improving crushing efficiency and effect. Attached Figure Description

[0037] Combination Figure 1 , Figure 3 and Figure 4As shown, a channel 21 is provided on the outer circumference of the crushing box 2, and a crushing chamber 22 is provided inside the crushing box 2. The channel 21 communicates with the crushing chamber 22. When the crushing box 2 rotates, the discharge port of the feed pipe 11 can correspond to the channel 21, and the circuit board in the feed pipe 11 can pass through the channel 21 and enter the crushing chamber 22; the feed port of the discharge pipe 12 can correspond to the channel 21, and the circuit board in the crushing chamber 22 can pass through the channel 21 and enter the discharge pipe 12, thus facilitating the discharge of the crushed circuit board. The crushing box 2 is connected to a crushing mechanism 3, which includes several crushing rollers 31 rotatably connected in the crushing chamber 22 and a drive assembly 32 for driving all the crushing rollers 31 to rotate. The crushing rollers 31 are evenly distributed at intervals, and the distance between two adjacent crushing rollers 31 is equal. Each crushing roller 31 is provided with a spiral blade 311 on its outer circumference, and two adjacent spiral blades 311 are staggered. The drive assembly 32 includes a gear 321 fixedly connected to one end of the crushing roller 31 and a second drive member 322 for driving one of the gears 321 to rotate. The second drive member 322 is fixedly connected to the crushing box 2 and is a motor.

Several partition plates 23 are fixedly connected at intervals on the inner wall of the crushing chamber 22 away from the channel 21. The distance between two adjacent partition plates 23 is equal, and all the crushing rollers 31 are located between the partition plates 23 and the channel 21.

[0038] Combination Figure 3 and Figure 5 As shown, the feed pipe 11 is connected to the extrusion assembly 4 and the bearing assembly 5. The bearing assembly 5 is located between the extrusion assembly 4 and the crushing box 2. The extrusion assembly 4 includes two extrusion plates 41 that are slidably connected in the feed pipe 11 and two third drive components 42 that are fixedly connected to the crushing box 1. The third drive component 42 is an electric cylinder. The signal output terminal of the controller is connected to the signal input terminal of the third drive component 42.

[0040] The implementation principle of a crushing device for recycling waste circuit boards according to an embodiment of this application is as follows:

[0041] The circuit board falls onto the support plate 51 through the feed pipe 11. The controller controls the third drive component 42 to open, which drives the corresponding extrusion plate 41 to slide towards the axis of the feed pipe 11, so that the circuit board is squeezed by the two extrusion plates 41. The fourth drive component 52 drives the support plate 51 to slide, so that the squeezed circuit board passes through the channel 21 and enters the crushing chamber 22. After being crushed by the crushing roller 31, the circuit board falls to the bottom of the crushing chamber 22. The first drive component 14 drives the crushing box 2 to rotate, so that the crushing box 2 rotates 180°, and the channel 21 aligns with the discharge pipe 12. The circuit board located at the bottom of the crushing chamber 22 is crushed again by the crushing roller 31 and finally discharged from the discharge pipe 12. The circuit board undergoes multiple crushing processes, which improves the crushing effect of the circuit board.
