Description

Technical Field

[0001] This invention belongs to the field of plastic-coated product recycling technology, and in particular, a recycling device for stainless steel plastic-coated products. Background Technology

[0002] Metal components in PVC-coated products are relatively expensive, so recycling them is the first priority when defects occur to minimize losses. Currently, metal recycling in PVC-coated products often involves heating the outer plastic layer, which is energy-intensive and slow. Melting the plastic also produces a burnt smell and significantly impacts the workshop environment. Therefore, finding a fast, energy-efficient, and hygienic method to remove metal components has become a key research focus in the industry. Among various PVC-coated products, food-grade stainless steel PVC-coated products are non-magnetic, resulting in poor heating performance and particularly significant recycling drawbacks.

[0004] Technical solution: A recycling device for stainless steel coated products includes a high-frequency heating box, a heating assembly mechanism, and an extraction mechanism. The high-frequency heating box is used for high-frequency heating of magnetic metals. The heating assembly mechanism is installed on the high-frequency heating box for transferring the recycled products and magnetizing the stainless steel tubes of the recycled products. The extraction mechanism is installed on the high-frequency heating box for extracting the stainless steel tubes of the recycled products.

[0005] Furthermore, the high-frequency heating chamber includes a chamber body, a transmitting coil, a temperature control unit, and a display. The temperature control unit is installed inside the chamber body, the transmitting coil is connected to the temperature control unit and located outside the chamber body, and the display is connected to the temperature control unit to display the temperature of the transmitting coil.

[0006] Furthermore, a water-cooled pump is connected to the transmitting coil, and the water-cooled pump is connected to circulating water for cooling the transmitting coil.

The heating assembly mechanism is fixed to the side wall of the housing by the mounting frame. The guide rail of the slide rail unit is mounted on the mounting frame. Two sets of station sliders are slidably connected to the guide rail. Station carrier rods are connected to the two sets of station sliders respectively. A clamping fixture for fixing and setting the recycled product is installed on the upper station carrier rod. A magnetic rod that cooperates with the transmitting coil is installed on the lower station carrier rod. A dual-station drive is installed on the guide rail. The dual-station drive is hinged to the upper and lower station carrier rods respectively through a drive linkage to synchronously drive the magnetic rod and the clamping fixture to move closer or further away from each other. The flipping unit is set between the housing and the upper station carrier rod to drive the working position of the clamping fixture to match the extraction mechanism.

[0008] Furthermore, the flipping unit includes a flipping gear and a flipping rack. The flipping gear is mounted on the lower work station support rod, and the flipping rack meshes with the flipping gear and has its end mounted on the housing.

[0019] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid obscuring the invention.

[0020] like Figure 1 As shown, a recycling device for stainless steel coated plastic products includes a high-frequency heating box 1, a heating assembly mechanism 2, and an extraction mechanism 3. The high-frequency heating box 1 is used for high-frequency heating of magnetic metals. The heating assembly mechanism 2 is installed on the high-frequency heating box 1 and is used to transfer the recycled product 4 and magnetize the stainless steel tube 41 of the recycled product 4. The extraction mechanism 3 is installed on the high-frequency heating box 1 and is used to extract the stainless steel tube 41 of the recycled product 4.

[0021] This invention utilizes a heating assembly mechanism 2 to magnetize the stainless steel tube 41 of the recycled product 4, and a high-frequency heating box 1 to heat the magnetic metal. The magnetic metal is embedded in the stainless steel tube 41. Through efficient heat conduction and rapid heating of the plastic-coated section of the recycled product 4, the invention provides feasible conditions for the extraction mechanism 3 to remove the stainless steel tube 41 from the recycled product 4. This invention uses a high-frequency heating device to heat the magnetized stainless steel tube 41, solving the problem of uniform and efficient heating of the stainless steel tube 41, and playing a positive role in the recycling of stainless steel plastic-coated products.

[0022] like Figure 2As shown, the high-frequency heating chamber 1 includes a chamber body 11, a transmitting coil 12, a temperature control unit 14, and a display 15. The temperature control unit 14 is installed inside the chamber body 11, and the transmitting coil 12 is connected to the temperature control unit 14 and located outside the chamber body 11. The display 15 is connected to the temperature control unit 14 and is used to display the temperature of the transmitting coil 12. A water-cooled pump 13 is connected to the transmitting coil 12, and the water-cooled pump 13 is connected to circulating water for cooling the transmitting coil 12.

[0023] The high-frequency heating box 1 has different heating temperatures for different products. Taking PP material as an example, it is better to maintain the temperature of the transmitting coil 12 at around 150℃. The magnetic recycling product 4 can be heated at 150℃ for 5-10 minutes. The specific temperature and time settings can be flexibly adjusted according to the extraction effect of the stainless steel tube 41.

[0024] like Figure 3 As shown, the heating assembly mechanism 2 includes a mounting frame 20, a slide rail unit, a dual-station drive 22, station carrier rods 25, a magnetic rod 26, a flipping unit, and a clamping fixture 29. The heating assembly mechanism 2 is fixed to the side wall of the housing 11 by the mounting frame 20. The guide rail 21 of the slide rail unit is mounted on the mounting frame 20. Two sets of station sliders 24 are slidably connected to the guide rail 21. Station carrier rods 25 are connected to the two sets of station sliders 24 respectively (the upper station carrier rod 25 needs to be flipped and is hinged to the station slider 24; the lower station carrier rod 25 does not need to be flipped and is hinged to the station slider 24). (4) The upper station carrier rod 25 is equipped with a clamping fixture 29 for fixing the recycled product 4, and the lower station carrier rod 25 is equipped with a magnetic rod 26 that cooperates with the transmitting coil 12. A dual-station drive 22 is installed on the guide rail 21. The dual-station drive 22 is hinged to the upper and lower station carrier rods 25 respectively through the drive connecting rod 23, and is used to synchronously drive the magnetic rod 26 and the clamping fixture 29 to move closer or further away from each other. The flipping unit is set between the housing 11 and the upper station carrier rod 25, and is used to drive the working position of the clamping fixture 29 to match the extraction mechanism 3. The dual-station drive 22 is a linear output device (pneumatic cylinder or electric cylinder can be used). When the dual-station drive 22 outputs, it causes the magnetic rod 26 to be inserted into the stainless steel tube 41, completing the magnetization action of the recycled product 4. The diameter of the magnetic rod 26 is slightly smaller than the inner diameter of the stainless steel tube 41, so as to ensure the heat conduction effect of the magnetic rod 26 on the stainless steel tube 41 as much as possible without affecting the smooth insertion.

[0025] The flipping unit includes a flipping gear 27 and a flipping rack 28. The flipping gear 27 is mounted on the lower station support rod 25, and the flipping rack 28 meshes with the flipping gear 27, with its end mounted on the housing 11. The flipping rack 28 is divided into a working section and a non-working section. During the magnetization and demagnetization processes, the flipping gear 27 engages with the non-working section to ensure that the position of the recycled product 4 remains vertically stable, facilitating the smooth implementation of the magnetization action. When the recycled product 4, after heating, needs to be matched with the station of the extraction mechanism 3, the flipping gear 27 meshes with the working section, realizing the position flipping of the recycled product 4 under the output of the dual-station drive 22.

[0026] like Figure 4 As shown, the extraction mechanism 3 includes a linear rotary motor 31, a gripper 32, an extraction switch 33, an industrial control box 34, and a bracket 35. The bracket 35 is mounted on the box 11, and the linear rotary motor 31 is mounted on the bracket 35. The output end of the linear rotary motor 31 is equipped with the gripper 32. Both the linear rotary motor 31 and the gripper 32 are electrically connected to the output end of the industrial control box 34. The input end of the industrial control box 34 is electrically connected to the extraction switch 33, which is mounted on the bracket 35. The extraction switch 33 is a proximity switch. The extraction switch 33 is positioned on the axis of the recycled product 4. Before the recycled product 4 is flipped, it remains within the collection range of the extraction switch 33, at which point the extraction mechanism 3 is not operating. When the recycled product 4 is flipped, it moves out of the collection range of the extraction switch 33, and the extraction mechanism 3 begins to operate after a predetermined time. The gripper 32 clamps the stainless steel tube 41, and under the operation of the linear rotary motor 31, the stainless steel tube 41 is removed from the recycled product 4.

[0027] like Figure 5 As shown, the recycled product 4 includes a stainless steel tube 41 and a plastic-coated outer shell 42 attached to the surface of the stainless steel tube 41. The stainless steel tube 41, which is composed of an austenitic structure, is non-magnetic and cannot be heated at high frequency by the transmitting coil 12.

[0028] In use, this invention selects a magnetic rod 26 of appropriate size based on the stainless steel tube 41 of the recycled product 4, and sets the heating temperature and heating time of the high-frequency heating box 1 according to the debugging results. After the preliminary preparations are completed, the recycled product 4 is first placed into the clamping fixture 29, and then the dual-station drive 22 outputs. Under the transmission action of the drive linkage 23, the magnetic rod 26 is smoothly inserted into the stainless steel tube 41. Then, the energized transmitting coil 12 inside the high-frequency heating box 1 heats the magnetic rod 26. After the set temperature and set heating time, the thermal conductivity of the magnetic rod 26 creates a thermal separation effect between the plastic-coated shell 42 and the stainless steel tube 41. Then, the dual-station drive 22 separates the recycled product 4 from the magnetic rod 26, ensuring that the magnetic rod 26 is within the radiation range of the transmitting coil 12 and avoiding the magnetic rod 26 burning dry (during the operation of the high-frequency heating box 1, the water cooling pump 13...). (Continuously supply circulating water to cool the transmitting coil 12); when the upper stationary support rod 25 rises to a certain height, the flipping gear 27 meshes with the working section of the flipping rack 28. Under the action of the gear and rack, the clamping fixture 29 flips the recycled product 4. During the flipping process, the recycled product 4 leaves the radiation range of the extraction switch 33, and the extraction mechanism 3 is ready to work. After the output of the dual-station drive 22 completes the flipping action, the stainless steel tube 41 enters the working range of the gripper 32. When the delayed start set by the extraction switch 33 takes effect, the gripper 32 clamps the stainless steel tube 41. The output of the linear rotation motor 31 causes the stainless steel tube 41 to separate from the plastic-coated outer shell 42 in a spiral advance. If the stainless steel tube 41 is magnetic, the magnetic rod 26 can be removed to avoid overheating and scorching of the plastic-coated surface.
