Description

Technical Field

[0001] This utility model relates to the field of plastic recycling technology, specifically to a high-efficiency and energy-saving plastic crushing production line and its debris recycling device. Background Technology

[0002] With the rapid development of the plastics industry, the amount of plastic waste generated is increasing year by year, making plastic recycling an important way to alleviate resource shortages and environmental pollution. Crushing is a key step in the plastic recycling process, aiming to break large pieces of plastic into smaller particles that are easier for subsequent processing. Currently, existing plastic crushing equipment often suffers from high energy consumption, low crushing efficiency, and incomplete debris recovery. Most crushing devices require separate drive units for the crushing and recycling mechanisms, which not only increases manufacturing costs but also leads to a significant increase in energy consumption. Furthermore, the crushed plastic particles are of uneven size, and traditional recycling and screening devices often use fixed screens, which are prone to clogging, affecting screening efficiency and recycling quality, making it difficult to meet the demands of efficient and energy-saving plastic recycling. In addition, the connection between the crushing and recycling stages in some equipment is not tight enough, and the crushed material is prone to scattering during transport, causing resource waste and secondary pollution. Therefore, we propose a high-efficiency and energy-saving plastic crushing production line and its debris recovery device to solve these problems. Utility Model Content

[0003] The purpose of this invention is to provide a high-efficiency and energy-saving plastic crushing production line and its debris recycling device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency and energy-saving plastic crushing production line and its debris recycling device, including a fixed frame, a recycling mechanism, a crushing mechanism, a crushing box, a feed inlet, and a mounting base. The mounting base is fixedly connected to the upper side of the fixed frame, and the crushing box is movably connected to the mounting base. A feed inlet is opened on one side of the crushing box. A feeding rack is set below the crushing box on the fixed frame. A recycling mechanism is set between the feeding rack and the crushing box, and the crushing mechanism is set inside the crushing box on the fixed frame.

[0005] Preferably, the crushing mechanism includes a drive motor, a drive box, a drive wheel, a first synchronous pulley, a second synchronous pulley, a synchronous belt, a crushing roller, and a crushing box. The drive box is fixedly connected to one side of the mounting base, and the drive motor is provided on one side of the mounting frame. The drive wheel is fixedly connected to the drive motor inside the drive box, and the crushing roller is movably connected to the mounting base. The first synchronous pulley is fixedly connected to the crushing roller inside the drive box, and the second synchronous pulley is movably connected to one side of the first synchronous pulley inside the drive box. A synchronous belt is fitted on the first synchronous pulley, the second synchronous pulley, and the drive wheel.

[0006] Preferably, the recycling mechanism includes a crankshaft, a drive rod, a transmission rod, a buffer frame, a buffer spring, a deflector plate, and a recycling net. A movable rod is fixedly connected to one side of the second synchronous pulley, a crankshaft is mounted on the movable rod, a drive rod is movably connected to the crankshaft, a transmission rod is movably connected to the side of the drive rod away from the crankshaft, and a deflector plate is movably connected to one side of the transmission rod.

[0007] Preferably, a buffer frame is symmetrically arranged below the fixed frame, and multiple buffer springs are evenly arranged on the buffer frame. The buffer frame is movably connected to the recycling net through the buffer springs, and the actuating plate is located on the recycling net.

[0008] Preferably, a filter screen is provided below the crushing roller on the mounting base. The filter screen has an arc-shaped structure and cooperates with the crushing roller.

[0009] Preferably, the recycling net is inclined, and the unloading rack is located below the recycling net.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. When the drive motor on one side of the fixed frame is powered on, it outputs rotational power, driving the drive wheel extending into the drive box to rotate synchronously. The drive wheel transmits power to the first and second synchronous wheels in the drive box through the synchronous belt on the outside. The first synchronous wheel is fixedly connected to the crushing roller in the mounting base. Therefore, the rotation of the first synchronous wheel will directly drive the crushing roller to rotate at high speed in the crushing box, providing mechanical force for plastic crushing. The crushing roller squeezes and crushes the material. The plastic to be crushed enters the crushing box from the feed port on one side of the crushing box and falls onto the high-speed rotating crushing roller, crushing large pieces of plastic into smaller particles. The crushed plastic particles fall onto the arc-shaped filter screen below the crushing roller. Particles that meet the size requirements can fall directly through the mesh of the filter screen and enter the recycling mechanism below. Large pieces of plastic that are not completely crushed cannot pass through the filter screen because they are too large. They will be driven and crushed again by the rotating crushing roller until they are crushed to the qualified size and then pass through the filter screen. The arc-shaped design reduces the dead angle between the filter screen and the crushing roller, avoiding material accumulation.

[0012] 2. When the crushing mechanism is running, the second synchronous pulley rotates synchronously with the synchronous belt, and the movable rod fixed on one side rotates accordingly. The crankshaft on the movable rod drives the drive rod connected to it through eccentric motion. The end of the drive rod away from the crankshaft is connected to the transmission rod. The reciprocating motion is transmitted to the actuating plate through the transmission rod, causing the actuating plate to perform high-frequency reciprocating motion on the recycling net. The screening function of the recycling net is the core of the recycling mechanism. Efficient screening is achieved through the cooperation of mechanical structures. The buffer frame below the fixed frame is connected to the recycling net through multiple buffer springs, so that the recycling net is in an "elastic suspension" state. When the actuating plate reciprocates on the recycling net, it will continuously apply a pushing or pulling force to the recycling net. Plastic debris falling from the crushing box through the filter screen first falls onto the recycling net. Small debris smaller than the mesh size of the recycling net passes through the mesh under the action of vibration and falls into the feeding frame below, completing the recycling. Larger, incompletely crushed particles are intercepted on the surface of the recycling net and move in the tilting direction with the vibration. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0019] like Figures 1-4As shown, this utility model proposes a high-efficiency and energy-saving plastic crushing production line and its debris recycling device, including a fixed frame 1, a recycling mechanism 2, a crushing mechanism 3, a crushing box 4, a feed inlet 5, and a mounting base 6. The mounting base 6 is fixedly connected to the upper side of the fixed frame 1, and the crushing box 4 is movably connected to the mounting base 6. The feed inlet 5 is opened on one side of the crushing box 4. The fixed frame 1 is provided with a feeding rack 7 below the crushing box 4. The recycling mechanism 2 is provided between the feeding rack 7 and the crushing box 4, and the crushing mechanism 3 is provided inside the crushing box 4.

[0020] In an optional embodiment, the crushing mechanism 3 includes a drive motor 301, a drive box 302, a drive wheel 303, a first synchronous wheel 304, a second synchronous wheel 305, a synchronous belt 306, a crushing roller 307, and a crushing box 4. The drive box 302 is fixedly connected to one side of the mounting base 6, and the drive motor 301 is provided on one side of the fixing frame 1. The drive motor 301 is fixedly connected to the drive wheel 303 inside the drive box 302, and the crushing roller 307 is movably connected inside the mounting base 6. The crushing roller 307 is fixedly connected to the first synchronous wheel 304 inside the drive box 302, and the second synchronous wheel 305 is movably connected to one side of the first synchronous wheel 304 inside the drive box 302. The synchronous belt 306 is sleeved on the first synchronous wheel 304, the second synchronous wheel 305, and the drive wheel 303.

[0021] The drive motor 301 on one side of the fixed frame 1 is energized and starts, outputting rotational power to drive the drive wheel 303 extending into the drive box 302 to rotate synchronously. The drive wheel 303 transmits power to the first synchronous wheel 304 and the second synchronous wheel 305 in the drive box 302 through the synchronous belt 306 sleeved on its outer side. The first synchronous wheel 304 is fixedly connected to the crushing roller 307 in the mounting base 6. Therefore, the rotation of the first synchronous wheel 304 will directly drive the crushing roller 307 to rotate at high speed in the crushing box 4, providing mechanical force for plastic crushing. The crushing roller squeezes and crushes the material, and the plastic to be crushed is extracted from the crushing roller. The material enters the crushing chamber through the feed inlet 5 on one side of the crushing chamber 4 and falls onto the high-speed rotating crushing roller 307, which crushes large pieces of plastic into smaller particles. The crushed plastic particles fall onto the arc-shaped filter screen 8 below the crushing roller 307. Particles that meet the size requirements can fall directly through the mesh of the filter screen 8 and enter the recycling mechanism 2 below. Large pieces of plastic that are not completely crushed cannot pass through the filter screen because they are too large. They will be driven and crushed again by the rotating crushing roller 307 until they are crushed to the qualified size and then pass through the filter screen. The arc-shaped design reduces the dead angle between the filter screen 8 and the crushing roller 307, avoiding material accumulation.

[0022] In an optional embodiment, the recycling mechanism 2 includes a crankshaft 201, a drive rod 202, a transmission rod 203, a buffer frame 204, a buffer spring 205, a deflector plate 206, and a recycling net 207. A movable rod 208 is fixedly connected to one side of the second synchronous pulley 305. The crankshaft 201 is mounted on the movable rod 208. The drive rod 202 is movably connected to the crankshaft 201. The transmission rod 203 is movably connected to the side of the drive rod 202 away from the crankshaft 201. The deflector plate 206 is movably connected to one side of the transmission rod 203.

[0023] In an optional embodiment, a buffer frame 204 is symmetrically arranged below the fixed frame 1, and a plurality of buffer springs 205 are arranged at equal intervals on the buffer frame 204. The buffer frame 204 is movably connected to the recycling net 207 through the buffer springs 205, and the actuating plate 206 is located on the recycling net 207.

[0024] In an optional embodiment, the mounting base 6 is provided with a filter screen 8 below the crushing roller 307. The filter screen 8 has an arc-shaped structure and cooperates with the crushing roller 307.

[0025] In an optional embodiment, the recycling net 207 is inclined, and the unloading rack 7 is located below the recycling net 207;

[0026] When the crushing mechanism 3 is running, the second synchronous pulley 305 rotates synchronously with the synchronous belt 306, and the movable rod 208 fixed on one side of it rotates accordingly. The crankshaft 201 on the movable rod 208 will drive the drive rod 202 connected to it through eccentric motion. The end of the drive rod 202 away from the crankshaft is connected to the transmission rod 203. The reciprocating motion is transmitted to the actuating plate 206 through the transmission rod, which drives the actuating plate 206 to perform high-frequency reciprocating motion on the recycling net 207.

[0027] The vibrating screening function of the recycling net 207 is the core of the recycling mechanism. It achieves efficient screening through mechanical structure cooperation. The buffer frame 204 below the fixed frame 1 is connected to the recycling net 207 through multiple buffer springs 205, so that the recycling net is in an "elastic suspension" state. When the actuating plate 206 moves back and forth on the recycling net 207, it will continuously apply a pushing or pulling force to the recycling net. Plastic debris falling from the crushing box 4 through the filter screen 8 first falls onto the recycling net 207. Small debris smaller than the mesh of the recycling net passes through the mesh under the action of vibration and falls into the feeding frame 7 below, completing the recycling. Larger, incompletely crushed particles are intercepted on the surface of the recycling net and move in the tilting direction with the vibration.

[0028] The working principle of this utility model is as follows: When using the device, the drive motor 301 on one side of the fixed frame 1 is energized and starts, outputting rotational power to drive the drive wheel 303 extending into the drive box 302 to rotate synchronously. The drive wheel 303 transmits power to the first synchronous wheel 304 and the second synchronous wheel 305 in the drive box 302 through the synchronous belt 306 sleeved on the outside. The first synchronous wheel 304 is fixedly connected to the crushing roller 307 in the mounting base 6. Therefore, the rotation of the first synchronous wheel 304 will directly drive the crushing roller 307 to rotate at high speed in the crushing box 4, providing mechanical force for plastic crushing. The crushing roller squeezes the material. The plastic to be crushed enters the crushing chamber 4 through the feed inlet 5 on one side and falls onto the high-speed rotating crushing roller 307, which crushes large pieces of plastic into smaller particles. The crushed plastic particles fall onto the arc-shaped filter screen 8 below the crushing roller 307. Particles that meet the size requirements can fall directly through the mesh of the filter screen 8 and enter the recycling mechanism 2 below. Large pieces of plastic that are not completely crushed cannot pass through the filter screen because they are too large. They will be driven and crushed again by the rotating crushing roller 307 until they are crushed to the qualified size and then pass through the filter screen. The arc design reduces the dead angle between the filter screen 8 and the crushing roller 307, avoiding material accumulation.

[0029] When the crushing mechanism 3 is running, the second synchronous pulley 305 rotates synchronously with the synchronous belt 306, and the movable rod 208 fixed on one side of it rotates accordingly. The crankshaft 201 on the movable rod 208 will drive the drive rod 202 connected to it through eccentric motion. The end of the drive rod 202 away from the crankshaft is connected to the transmission rod 203. The reciprocating motion is transmitted to the actuating plate 206 through the transmission rod, which drives the actuating plate 206 to perform high-frequency reciprocating motion on the recycling net 207.

[0030] The vibrating screening function of the recycling net 207 is the core of the recycling mechanism. It achieves efficient screening through mechanical structure cooperation. The buffer frame 204 below the fixed frame 1 is connected to the recycling net 207 through multiple buffer springs 205, so that the recycling net is in an "elastic suspension" state. When the actuating plate 206 moves back and forth on the recycling net 207, it will continuously apply a pushing or pulling force to the recycling net. Plastic debris falling from the crushing box 4 through the filter screen 8 first falls onto the recycling net 207. Small debris smaller than the mesh of the recycling net passes through the mesh under the action of vibration and falls into the feeding frame 7 below, completing the recycling. Larger, incompletely crushed particles are intercepted on the surface of the recycling net and move in the tilting direction with the vibration.

[0031] It should be understood that the specific embodiments described above are for illustrative purposes or to explain the principles of this utility model, and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
