Description

Technical Field

[0001] This invention relates to the field of plastic tableware processing, and in particular to an environmentally friendly tableware thermoforming system based on recycled waste plastic structures. Background Technology

[0002] With the popularization of environmental protection concepts, thermoforming technology for producing environmentally friendly tableware by reshaping waste plastics has become a hot topic. In large-scale production, the thermoforming process generates a large amount of waste material. Recycling and reprocessing this waste into reusable raw materials is a key path to reduce costs, increase efficiency, and practice green production.

[0003] Currently, the recycling of tableware waste follows a process of "collection-crushing-washing-granulation-blending-reheat pressing." However, existing technologies face numerous bottlenecks in the crushing and subsequent connection stages, severely restricting the utilization rate of recycled materials, the quality of recycled tableware, and the promotion of industrialization. The waste materials requiring crushing exhibit high toughness due to residual internal stress from previous hot pressing. Existing single-impact or shear crushers are prone to "blade entanglement" and "wall sticking," leading to crushing interruptions. Furthermore, the output particles show large deviations in particle size, with coarse particles mixed with fine powder. This reduces the compatibility with virgin materials, making subsequently hot-pressed tableware prone to defects such as wall thickness deviations and surface pinholes, resulting in drastic fluctuations in mechanical properties and failure to meet usage standards. Summary of the Invention

[0004] This invention provides an environmentally friendly tableware thermoforming system based on recycled waste plastic structures to address the problems of poor crushing efficiency and particle quality in the recycling of existing environmentally friendly tableware as mentioned in the background art.

[0006] The recycling mechanism includes a crushing unit connected to a support platform via a fixed frame, and a storage bin connected to a mixing bin is provided at the bottom of the crushing unit.

[0007] The shredding unit includes a shredding bin connected to a fixed frame. A drive frame is rotatably connected inside the shredding bin. The outer circumference of the drive frame has an array of mounting slots. A guide slot is provided on the outer wall of the drive frame corresponding to the mounting slot. A cutting tool unit is provided inside the mounting slot. The cutting tool unit includes pressure plates slidably installed inside the mounting slot. Cutting blades are slidably connected between the pressure plates. A control plate is slidably connected between the cutting blades. A limit groove is provided on the outer wall of the shredding bin corresponding to the guide groove. Drive bolts are provided at both ends of the control plate, extending from the guide groove and slidably installed in the limit groove.

[0008] The present invention is further configured such that a feed inlet is provided on one side of the crushing bin, and a screen is provided at the bottom of the crushing bin corresponding to the position of the storage bin.

[0009] The present invention is further configured such that limit blocks are symmetrically arranged at both ends of the pressure plate, and a docking groove is provided on the inner wall of the mounting groove corresponding to the position of the limit blocks, and one end of the limit blocks extends into the docking groove and the two are slidably connected.

[0010] The present invention is further configured such that a baffle is slidably installed on the inner wall of the mounting groove near the pressure plate, and an elastic element two is provided on the outer wall of the baffle, one end of which is connected to the mounting groove.

[0011] The present invention is further configured such that the bottom of the pressure plate is evenly provided with docking holes, and a nail plate is slidably installed inside the pressure plate at the position corresponding to the docking holes. The bottom end of the nail plate is slidably connected to the inner wall of the docking holes. A fixing seat is provided at the top of the nail plate, and a docking block is slidably installed inside the fixing seat. An elastic element is provided at the bottom of the docking block. A pressure block is provided on the outer wall of the cutter at the position corresponding to the docking block, and the pressure block is slidably connected to the docking block.

[0012] The invention is further configured such that the control board has a drive groove on the outer wall near the cutter, and a connecting plate is provided on the outer wall of the cutter at the position corresponding to the drive groove, with one end of the connecting plate extending into the drive groove and the two being slidably connected.

[0013] The present invention is further configured such that a dust collection chamber is provided inside the drive frame, a vent pipe is provided on the top of the control board, the top end of the vent pipe extends into the dust collection chamber, a second air extraction hole is provided on the outer wall of the control board near the bottom, the second air extraction hole is connected to the vent pipe, and a first air extraction hole is provided on the cutter surface corresponding to the second air extraction hole.

[0014] The beneficial effects of the environmentally friendly tableware thermoforming system based on recycled waste plastic structure of the present invention are as follows:

[0015] 1. Improves crushing efficiency and particle quality, ensuring stable mechanical properties of recycled tableware. The rotating drive frame drives the cutter unit in a cyclical operation. Guided by gravity and a limiting slide, the cutter unit operates according to a preset logic: the pressure plate extends from the mounting slot and remains in contact with the baffle and elastic element, achieving pre-compacted positioning and offset blocking of the waste material; the control plate moves along the limiting slide via the drive bolt, pushing the connecting plate through the drive slot to extend the cutter. The cutter presses down on the connecting block through the pressure block, and with the help of the elastic element, the pressure plate first compacts the waste material before driving the pressure plate to tighten, ultimately achieving efficient cutting. This linkage structure fundamentally solves the problems of waste material entanglement, sticking to the wall, and interruption of crushing. Combined with the screening of the screen in the crushing bin, it ensures uniform particle size, improves the compatibility with new materials, reduces defects in hot-pressed tableware, and makes the fluctuation of mechanical properties controllable, meeting usage standards.

[0016] 2. Avoiding heat damage during crushing and reducing equipment maintenance costs. This system abandons the traditional high-speed crushing design. The drive frame drives the cutter unit to rotate and circulate, relying on gravity and mechanical linkage to complete the crushing. There is no intense friction heat generation, controlling the temperature of the crushed material bin from the source. After the cutter is precisely aligned with the air extraction port 1 and air extraction port 2 on the control board, the external air extraction mechanism forms a negative pressure path through the dust collection bin and air pipe. During air extraction, residual heat is simultaneously removed, preventing high-temperature adhesion and blockage of waste materials, avoiding thermal and oxidative degradation of recycled materials, ensuring their temperature resistance and impact resistance, and meeting microwave heating requirements. The low-temperature environment also reduces cutter wear, lowering maintenance frequency and costs.

[0017] 3. Eliminate the hazards of fine powder and optimize the production environment and finished product quality. Fine powder generated during crushing is drawn into a dust collection bin for centralized treatment via an extraction system consisting of extraction ports one and two, and a ventilation pipe. This prevents the powder from flying and contaminating the molds during hot pressing, causing scratches, and simultaneously inhibits the diffusion of volatile substances, improving the workshop environment. The bottom of the control panel is positioned between the cutters to form a secondary barrier, working in conjunction with baffles to prevent fine powder from mixing with qualified particles, avoiding defects in hot pressing pores, and improving the mechanical properties and appearance quality of recycled tableware.

[0032] Please see Figure 1 - Figure 8An environmentally friendly tableware thermoforming system based on waste plastic remodeling structure includes a support platform 1, a mixing bin 2 installed on the top of the support platform 1, a feeding unit 21 on one side of the mixing bin 2, a thermoforming unit 5 at the outer end of the feeding unit 21, and a raw material bucket 3 and a recycling mechanism 4 connected to the top of the mixing bin 2 respectively.

[0033] The recycling mechanism 4 includes a crushing unit 41 connected to the support platform 1 via a fixed frame 42, and a storage bin 43 connected to the mixing bin 2 is provided at the bottom of the crushing unit 41.

[0034] The shredding unit 41 includes a shredding bin 411 connected to a fixed frame 42. A drive frame 415 is rotatably connected inside the shredding bin 411. Several mounting slots 4152 are arrayed on the outer circumference of the drive frame 415. A guide slot 4153 is provided on the outer wall of the drive frame 415 at the position corresponding to the mounting slot 4152. A tool unit 416 is provided inside the mounting slot 4152. The tool unit 416 includes a pressure plate 4161 slidably installed inside the mounting slot 4152. A cutter 4162 is slidably connected between the pressure plates 4161. A control plate 4163 is slidably connected between the cutters 4162. A limit groove 414 is provided on the outer wall of the shredding bin 411 at the position corresponding to the guide groove 4153. Drive bolts 41634 are provided at both ends of the control plate 4163, extending out of the guide groove 4153 and slidably installed in the limit groove 414. A feed inlet 413 is provided on one side of the crushing bin 411, and a screen 412 is provided at the bottom of the crushing bin 411 corresponding to the storage bin 43.

[0035] By adopting the above technical solution, the drive frame 415 forms a radial sliding relationship with the cutter unit 416 through the mounting groove 4152, and multiple sets of circumferential arrays achieve continuous crushing. The guide groove 4153 and the limiting slide groove 414 constitute a cam mechanism, and the drive bolt 41634 controls the extension and retraction sequence of the cutter unit 416 to ensure that it cuts at the bottom of the crushing bin 411. The cutter unit 416 has a three-stage mechanism working in concert: the pressure plate 4161 radially presses, the cutter 4162 uses a wedge mechanism to achieve axial cutting, and the control plate 4163 triggers the suction function. The air extraction system removes fine powder by aligning the channels. The screen 412 has a stepped aperture and is installed at an angle.

[0036] The bottom of the pressure plate 4161 is evenly provided with docking holes 41611. Inside the pressure plate 4161, a nail plate 41613 is slidably installed at the position corresponding to the docking holes 41611. The bottom end of the nail plate 41613 is slidably connected to the inner wall of the docking holes 41611. A fixing seat 41614 is provided at the top of the nail plate 41613. A docking block 41615 is slidably installed inside the fixing seat 41614. An elastic element 41616 is provided at the bottom of the docking block 41615. A pressure block 41622 is provided on the outer wall of the cutter 4162 at the position corresponding to the docking block 41615. The pressure block 41622 is slidably connected to the docking block 41615. The control board 4163 has a drive groove 41631 on its outer wall near the cutter 4162. A connecting plate 41623 is provided on the outer wall of the cutter 4162 at the position corresponding to the drive groove 41631. One end of the connecting plate 41623 extends to the drive groove 41631 and the two are slidably connected.

[0037] By adopting the above technical solution, the nail plate 41613 forms a vertical sliding pair with the pressure plate 4161 through the mating hole 41611, and the phased extension is achieved through the wedge mechanism to prevent the pre-piercing of waste material from slipping. The pressure block 41622 transmits force with a curved surface fit, and the elastic element 41616 buffers the force to keep the cutting stable. The variable pitch drive groove 41631 of the control plate 4163 realizes the "fast advance-slow cut" of the cutter 4162.

[0038] The pressure plate 4161 has symmetrical limit blocks 41612 at both ends. The inner wall of the mounting groove 4152 has a docking groove 4154 corresponding to the position of the limit block 41612. One end of the limit block 41612 extends into the docking groove 4154 and the two are slidably connected. The drive frame 415 has a dust collection chamber 4151 inside. The top of the control plate 4163 has a vent pipe 41633. The top end of the vent pipe 41633 extends into the dust collection chamber 4151. The outer wall of the control plate 4163 has a second air extraction hole 41632 near the bottom. The second air extraction hole 41632 is connected to the vent pipe 41633. The cut surface of the cutter 4162 has an air extraction hole 41621 corresponding to the position of the second air extraction hole 41632.

[0039] By adopting the above technical solution, the limiting block 41612 forms a bidirectional sliding connection with the mounting groove 4152 via the docking groove 4154, and the symmetrically arranged anti-pressure plate 4161 deflects, ensuring the extension stroke and preventing detachment. After the cutter 4162 is in place, the first air extraction hole 41621 and the second air extraction hole 41632 are aligned to form a channel, and then the dust is drawn into the dust collection bin 4151, resulting in an extremely high dust capture rate.

[0040] Working principle and usage process of this invention:

[0041] During use, the raw material is fed to the upper and lower molds in the hot pressing unit 5 through the feeding unit 21. Then, the raw material is hot pressed by the upper mold to form tableware. However, burrs will be generated during the hot pressing process of the tableware. Therefore, after the tableware is cooled, the waste edges generated during the tableware production process are removed manually or mechanically. The removed waste edges will fall to the bottom of the lower mold. Then, the waste material is uniformly transported by the conveying components outside the hot pressing unit 5 to the inlet 413 of the recycling mechanism 4, where it is crushed by the components of the recycling mechanism 4.

[0042] When the recycling mechanism 4 is in use, the external drive component first drives the drive frame 415 and its auxiliary parts to rotate clockwise. Then, the waste material or defective waste generated during the production process is put into the crushing bin 411 of the crushing unit 41 through the feed port 413. The put-in waste material will fall between the inner wall of the crushing bin 411 and the drive frame 415. With the rotation of the drive frame 415, it is smoothly carried to the bottom of the crushing bin 411. At the same time, the drive frame 415 drives the cutter unit 416 to rotate and circulate synchronously, realizing continuous crushing operation and greatly improving crushing efficiency.

[0043] When the cutter unit 416 is located at the feed inlet 413, it retracts into the mounting slot 4152 of the drive frame 415, effectively avoiding interference with the feeding process and ensuring smooth feeding. When the cutter unit 416 rotates to the position below the crushing bin 411, under the precise guidance of the limiting slide 414, the drive bolt 41634 on the control plate 4163 moves along the trajectory of the limiting slide 414, causing the bottom of the control plate 4163 to extend out of the mounting slot 4152. During the movement, the drive slot 41631 of the control plate 4163 pushes the connecting plate 41623 of the cutter 4162, thereby synchronously driving the cutter 4162 to move out of the mounting slot 4152.

[0044] The cutter 4162 presses down on the mating block 41615 of the pressure plate 4161 via the pressure block 41622. Under the continuous pushing action of the baffle 4164 and the second elastic element 41641, the pressure plate 4161 and the cutter 4162 will not separate initially. The pushing force is first transmitted to the nail plate 41613 of the pressure plate 4161, causing the bottom of the nail plate 41613 to extend from the mating hole 41611 and press the waste material, initially fixing the position of the waste material. When the first elastic element 41616 is compressed to a certain extent, the pushing force is converted into a force that drives the pressure plate 4161 to extend outward, so that the bottom of the pressure plate 4161 tightly presses against the waste material to complete the secondary compaction. With the blocking action of the baffle 4164, the waste material can be effectively prevented from shifting during cutting, solving the problem of waste material entanglement with the cutter from the root.

[0045] Because the mating surfaces of the pressure block 41622 and the connecting block 41615 are both inclined, and with the guiding effect of the inclined surfaces and the continuous pushing force of the elastic element 41641, the cutter 4162 and the pressure plate 4161 are not easily separated, ensuring cutting stability and ensuring uniform particle size of the produced particles. Subsequently, under the pushing force of the control plate 4163, the cutter 4162 is pushed out to precisely cut the compacted waste. After the cutter 4162 moves to a position close to the bottom of the crushing bin 411, it cannot move further down. The pushing force of the control plate 4163 is then converted into the power to separate the cutter 4162 from the pressure block 41622.

[0046] When waste materials are crushed, they easily generate powder, which can affect the quality of subsequent hot pressing. To solve this problem, when the bottom of the control plate 4163 moves to be parallel to the blade of the cutter 4162, the first air extraction hole 41621 of the cutter 4162 is precisely connected to the second air extraction hole 41632 of the control plate 4163. The external air extraction mechanism generates negative pressure through the dust collection chamber 4151, and connects the two air extraction holes through the air pipe 41633 of the control plate 4163 to quickly extract the fine powder generated by cutting. At the same time, the bottom of the control plate 4163 is stuck between the cutter 4162 to further prevent waste materials from mixing with fine powder, thus avoiding secondary pollution and subsequent hot pressing defects.

[0047] After cutting, the cutter 4162 does not retract immediately. It rotates with the drive frame 415, causing the cut waste to move upwards. When the cutter unit 416 moves to the top of the scrap bin 411, the control plate 4163 retracts under the guidance of the limiting slide 414. It resets under its own drive and the gravity of the cutter 4162 and the pressing block 41622. During the retraction of the cutter 4162, the pressing block 41622 scrapes and cleans its surface. Waste that does not meet the size requirements will enter the next round of cutting with the cutter unit 416, ensuring that the particle size meets the standards. Qualified particles fall through the screen 412 of the scrap bin 411 into the storage bin 43. The recycled particles in the storage bin 43 and the new material in the raw material bucket 3 are drawn into the mixing bin 2 according to a preset ratio. After thorough mixing, they are conveyed through the feeding unit 21 to the hot pressing unit 5 for hot pressing, forming a closed-loop recycling chain, improving waste utilization and reducing production costs.

[0048] In summary, compared with the prior art, the embodiments of the present invention have the following advantages:

[0049] Advantage 1: Improved crushing efficiency and particle quality. The drive frame 415 drives the cutter unit 416 to rotate and circulate. Guided by the limiting slide groove 414, the pressure plate 4161 extends from the mounting groove 4152 and is pressed together by the baffle 4164 and the second elastic element 41641 to achieve pre-positioning of waste material. The control plate 4163 moves through the drive bolt 41634, and drives the cutter 4162 to extend through the drive groove 41631 and the connecting plate 41623. The cutter 4162 presses down on the docking block 41615 through the pressure block 41622, and pushes the nail plate 41613 to compact it a second time with the help of the first elastic element 41616. Then, the pressure plate 4161 is driven to press it tightly before cutting. This avoids blade entanglement and sticking to the wall from the source. With the help of the screen 412, it ensures uniform particle size and improves compatibility with new materials.

[0050] Advantage 2: Avoids heat damage from crushing and damaging the recycled material. This system uses mechanical linkage between the drive frame 415 and the cutter unit 416 for crushing, eliminating the need for intense friction and heat generation. After the first air extraction port 41621 of the cutter 4162 is connected to the second air extraction port 41632 of the control board 4163, the external air extraction mechanism creates negative pressure through the dust collection bin 4151 and the vent pipe 41633, simultaneously removing residual heat and preventing the waste material from sticking and degrading at high temperatures, thus ensuring the performance of the recycled material. At the same time, it reduces cutter wear and lowers maintenance costs.

[0051] Advantage 3: Elimination of fine powder hazards. Crushed fine powder is drawn into the dust collection bin 4151 for centralized processing via air extraction holes 1 (41621), 2 (41632), and vent pipe 41633, preventing contamination of the mold and workshop environment. The control board 4163 is positioned between the cutters 4162, and together with the baffle 4164, it prevents fine powder from mixing with qualified particles, eliminating defects such as hot-pressing air holes and scratches, and improving the quality of the finished product.

[0052] Fourthly, it achieves closed-loop green production. The qualified particles crushed by the crushing unit 41 enter the storage bin 43 through the screen 412, and are mixed with the new material in the raw material bucket 3 according to the ratio and sent to the mixing bin 2 for uniform mixing. Then, the material is transported to the hot pressing molding unit 5 by the feeding unit 21. There is no need for additional cleaning and granulation processes, which shortens the process, improves the utilization rate of recycled materials, and balances efficiency and environmental protection.
