Description

Technical Field

[0001] This utility model relates to the field of waste recycling technology, and more specifically, to an automated plastic product recycling and waste recycling machine. Background Technology

[0002] Plastic products are a general term for household and industrial products made primarily from plastics. This includes products manufactured using processes such as injection molding and thermoforming. Plastics are a type of synthetic polymer material with plasticity, and plastic products are recyclable. Therefore, recycled plastic products need to be crushed and processed.

[0003] The plastic product scrap recycling machine disclosed in application number CN202422533709.X is also an increasingly mature technology. When the plastic product scrap recycling machine is in use, the shredded fertilizer packaging bags discharged from the crushing box will be sent back to the crushing box through the cooperation of the screw conveyor and the guide box, so that the fertilizer packaging bags can be shredded in a cycle. This ensures that there are no large pieces or long strips of fertilizer packaging bags in the shredded fertilizer packaging bags, ensuring the crushing effect of fertilizer packaging bags during recycling. At the same time, it also reduces the input of labor and improves work efficiency.

[0004] Based on this, we agree with the advantages of the aforementioned products, but the following drawbacks still exist: In the use of this type of material recycling machine, because plastic products are relatively light, they may be thrown out or floated at the top of the crushing component. Moreover, a large amount of plastic powder is generated during the crushing process, and the plastic powder floating in the air can easily cause environmental pollution. Utility Model Content

[0005] The purpose of this invention is to provide an automated plastic product recycling and shredding machine to solve the environmental pollution problems caused by plastic products being thrown out or floating and plastic powder, as mentioned in the background art.

[0006] This utility model provides an automated plastic product recycling and shredding machine, including a shredding machine, a shredding device inside the shredding machine, a pressure device at the top of the shredding machine, and a dust collection device on one side of the shredding machine. The crushing device includes a crushing machine with a central shaft symmetrically installed inside. One side of the central shaft passes through one end of the crushing machine and is fixedly connected to the output end of a motor. The motor is fixedly installed at one end of the crushing machine. A first crushing roller and a second crushing roller are sleeved on the surface of the central shaft. The end of the central shaft away from the motor passes through the crushing machine and is fixedly connected to a main gear and a driven gear. A partition plate is provided on both sides of the gap between the first crushing roller and the second crushing roller. The pressure device includes a feed hopper fixedly installed at the top of the crusher, a U-shaped plate fixedly installed at the top of the feed hopper, an electric telescopic rod fixedly installed at the middle of the top of the U-shaped plate, and the telescopic end of the electric telescopic rod connected to the pressure plate through a convex ring.

[0007] In this embodiment, the rotation of the central shaft is driven by an electric motor, which causes the main gear to mesh with the driven gear, thereby causing the two central shafts to drive the two crushing rollers to rotate synchronously. This allows the two interference-fitted crushing rollers to tear and crush the plastic products. The partition plate prevents the plastic products from slipping off the sides of the crushing rollers. The telescopic end of the electric telescopic rod has a self-locking property after moving to the appropriate length. The telescopic end of the electric telescopic rod pushes or pulls the pressure plate to raise or lower, so that the pressure plate applies pressure to the plastic products and pushes them into the interior of the two crushing rollers. This prevents the plastic products from being thrown out or floating up as the crushing rollers rotate because they are relatively light.

[0008] In one embodiment of this utility model, the dust collection device includes a negative pressure machine on one side of the shredder, the inlet end of the negative pressure machine is connected to the side of the shredder, the outlet end of the negative pressure machine is located inside the dust collection box, both ends of the dust collection box are provided with exhaust ports and matching filters are provided inside, and a dust collection drawer is slidably provided at the bottom of the inside of the dust collection box.

[0009] In this solution, the negative pressure is generated by collecting the air pressure inside the dust collection box when the negative pressure machine is started. The negative pressure causes the dust inside the crusher to be sucked into the outlet end through the inlet end of the negative pressure machine and enter the dust collection box, where it falls onto the dust collection drawer.

[0010] In one embodiment of this utility model, a screen plate is inclinedly installed at the bottom end of the first crushing roller and the second crushing roller of the external crusher. A guide plate is installed at the bottom end of the screen plate. A discharge port is opened at the bottom end of the external crusher. A discharge port is opened at one end of the external crusher located on the screen plate and a discharge hopper is fixedly installed on the outside.

[0011] In this scheme, qualified plastic products are allowed to fall through the aperture of the inclined screen plate and slide into the discharge port along the guide plate. Unqualified plastic products slide through the discharge port and discharge hopper along the inclined screen plate.

[0012] In one embodiment of this utility model, a workbench is fixedly installed at the bottom of the external crusher. A matching rectangular groove is provided on the surface of the workbench at the feeding port. A long groove is provided on the side of the rectangular groove. A recycling box is movably installed inside the long groove. Support legs are provided at the four corners and the middle of the bottom of the workbench, and a reinforcing rib is provided in the middle. The bottom of each support leg is provided with a universal wheel with a wheel brake.

[0013] In this design, the workbench provides a solid support platform for the shredder, the rectangular trough allows plastic products to fall directly from the discharge port, the long trough facilitates the installation of a recycling bin to collect substandard plastic products that slide out of the discharge hopper, the support legs enhance the stability of the overall structure, the reinforcing ribs increase the structural strength and rigidity between the support legs, and the casters facilitate flexible movement and positioning of the equipment, ensuring safety.

[0014] In one embodiment of this utility model, the first crushing roller and the second crushing roller are interference-fitted, the central shaft passes through the surface of the crushing machine and is fitted with a bearing sleeve, the dust collection drawer is provided with a handle at the middle of its outer side, and the top of the recycling box is fixedly installed with a handle and a non-slip ring is fitted on its surface.

[0015] In this design, the two interference-fit crushing rollers provide better crushing effect, the bearing sleeve reduces friction and wear between the central shaft and the crushing machine, the handle makes it easy to pull the dust collection drawer, the lifting handle makes it easy to retrieve the recycling box, and the anti-slip ring increases friction.

[0016] In one embodiment of this utility model, a switch panel is provided at one end of the external crusher, and a motor switch, an electric telescopic rod switch and a negative pressure machine switch are respectively installed on one side of the switch panel. The switch panel is electrically connected to an external power supply.

[0017] In this solution, power is supplied to the electrical equipment through a switch panel, and independent switches provide independent protection for the electrical equipment.

[0018] Compared with the prior art, the beneficial effects of this utility model are: (1) The telescopic end of the electric telescopic rod has a self-locking property after moving to a suitable length. The telescopic end of the electric telescopic rod pushes or pulls the pressure plate to raise and lower, so that the pressure plate applies pressure to the plastic product and puts it into the interior of the two crushing rollers, so as to avoid the plastic product being thrown out or floating up as the crushing rollers rotate due to its light weight. (2) By starting the negative pressure machine, the air pressure inside the dust collection box is collected and negative pressure is generated. The negative pressure causes the dust inside the crusher to be sucked into the outlet end through the inlet end of the negative pressure machine and enter the dust collection box and fall onto the dust collection drawer. The filter screen is used to discharge the sucked-in gas from the dust collection box to ensure that a negative pressure environment is continuously formed inside the dust collection box.

The telescopic end of the electric telescopic rod 311 pushes or pulls the pressure plate 312 to raise and lower, so that the pressure plate 312 applies pressure to the plastic product and forces it into the interior of the two crushing rollers. This prevents the plastic product from being thrown out or floating due to its light weight as the crushing rollers rotate. The motor 211 drives the rotation of the central shaft 210, causing the main gear 214 of the central shaft 210 to mesh with the driven gear 215, thereby causing the two central shafts 210 to rotate synchronously. The rotation of the central shafts 210 drives the first crushing roller 212 and the second crushing roller 213 to rotate synchronously, so that the two interference-fitted crushing rollers can effectively tear and crush the plastic product. The crushed plastic products fall onto the inclined screen plate 111, allowing qualified plastic products to fall through the aperture of the screen plate 111 and slide along the guide plate 112 into the discharge port. Unqualified plastic products slide along the inclined screen plate 111, pass through the discharge port and discharge hopper 113, and fall into the recycling box 117 for subsequent crushing operations. The start of the negative pressure machine 410 collects the air pressure inside the dust collection box 411, thereby generating negative pressure. The negative pressure causes the dust inside the crushing machine 100 to be sucked into the outlet end through the inlet end of the negative pressure machine 410 and enter the dust collection box 411, falling onto the dust collection drawer 413. The filter screen 412 is used to discharge the sucked-in air from the dust collection box 411, ensuring that a negative pressure environment is continuously formed inside the dust collection box 411.
