A recycled polyester sheet making equipment

Abstract

This invention relates to the field of plastic recycling and processing equipment technology, and discloses a recycled polyester sheet making device, including a support frame, a fixed frame fixedly connected to the top of the support frame, and an electric push rod fixedly connected to the end of the fixed frame away from the support frame. This invention utilizes the feature of the aforementioned pressing plate pressing the top of the sliding square plate. A pressure application component is set inside the device, and the air inlet pipe injects sufficient gas into the sliding groove. This gas is injected between the sliding square plate and the sheet through the moving mechanism. As the air intake increases, the bulge will spread outwards. Because the sheet is pressed by the sliding plate, the flow resistance in the pressed area is greater than in other positions. This makes it impossible for the edge of the bulge to continue to expand outwards after reaching the pressed edge, and the bulge will expand to other positions. Through the application of the above-mentioned component, the problem of excessive adhesion area between the sheet and the sliding square plate due to the bulge expanding outwards from a single position is effectively prevented during the use of the device.

Description

Technical Field

[0001] This invention relates to the field of plastic recycling and processing equipment technology, specifically to a recycled polyester sheet production equipment. Background Technology

[0002] Polyester is a general term for polymers obtained by polycondensation of polyols and polyacids, mainly referring to polyethylene terephthalate. It is a class of high-performance engineering plastics, widely used in packaging, electronics, medical and health, construction, automobiles and other fields. Packaging is the largest non-fiber application market for polyester, and it is also the fastest growing area for PET. However, because polyester is difficult to degrade naturally, in order to avoid pollution to the environment by a large amount of waste polyester products, waste polyester is usually recycled and reused through processing steps such as recycling, crushing, washing, drying and regenerating granulation.

[0003] During the sheet-making process, plastic particles need to be melted and extruded into sheets quickly. The finished product is relatively thin and has a certain degree of toughness. In order to improve the subsequent demolding efficiency, air demolding is often used. However, in actual applications, after the demolding gas enters the gap between the finished product and the mold, it will quickly form a bulge. After the bulge expands to the edge, it will leak air in one direction. The bulge cannot completely cover the contact surface, and the finished product and the mold are still stuck together, resulting in a reduction in demolding efficiency. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a recycled polyester sheeting device, including a support frame, a fixed frame fixedly connected to the top of the support frame, an electric actuator fixedly connected to the end of the fixed frame away from the support frame, a heater fixedly connected to the output end of the electric actuator, and a pressing plate fixedly connected to the bottom of the heater, and further comprising: The limiting mechanism is fixedly installed on the top of the bracket; The auxiliary mechanism is fixedly installed on the inner wall of the support. The moving mechanism is slidably mounted on the inner wall of the auxiliary mechanism. During use, the electric push rod pushes the heater and the pressing plate downwards to complete the basic pressing process.

[0005] Preferably, the limiting mechanism includes: The fixing component is fixedly installed on the top of the bracket; The pressure application component is slidably disposed on the outer wall of the pressure plate; Before use, workers need to put polyester granules into the inner wall of the fixing component, and then push the electric actuator to press the pressing plate downwards.

[0006] Preferably, the auxiliary mechanism includes: The power assembly is fixedly installed on the inner wall of the bracket; The air intake assembly is fixedly mounted on the top end of the power assembly; In this process, after the equipment completes the basic pressing process, the power component pushes the fixed component upward to perform the basic demolding process.

[0007] Preferably, the moving mechanism includes: A sliding component is slidably disposed on the inner wall of the intake component; The circulation component is located on the inner wall of the power component; The high-pressure gas from the outside enters the inner wall of the power component through the air intake component, and is then transmitted to the gap between the finished product and the fixed component through the flow component and the sliding component.

[0008] Preferably, the fixing component includes a fixing plate 1 fixedly connected to the top of the bracket, a through hole groove is provided at the top center of the fixing plate 1, and a sliding square plate is slidably connected to the inner wall of the through hole groove; Under normal conditions, the power component will drive the sliding square plate to the bottom of the inner wall of the through-hole groove, so that the top of the sliding square plate and the inner wall of the through-hole groove form a lower mold.

[0009] Preferably, the pressure application component includes a groove on both sides of the pressing plate, a sliding plate is slidably connected to the inner wall of the groove, and a spring is fixedly connected to the top of the sliding plate. Under normal conditions, the sliding plate is at the lowest position on the inner wall of the first groove, and the spring is in a relaxed state. When the sliding plate is subjected to an upward thrust, the spring is compressed and deformed, accumulating potential energy.

[0010] Preferably, the power assembly includes a fixing plate two fixedly connected to the inner wall of the bracket, an electric actuator two fixedly connected to the top of the fixing plate two, and a metal rod fixedly connected to the output end of the electric actuator two; One end of the metal rod away from the second electric push rod is fixedly connected to the bottom of the sliding square plate. After the equipment completes the pressing, as the first electric push rod drives the pressing plate to move upward, the second electric push rod pushes the metal rod to move upward in sync.

[0011] Preferably, the air intake assembly includes a groove 2 opened at one end of the metal rod away from the electric push rod 2, an air intake pipe is connected through the top of the side wall of the metal rod, and a spring 1 is fixedly connected to the inner wall of the groove 2. The external high-pressure gas is transmitted to the inner wall of the slide groove two through the air inlet pipe, and pushes the sliding component to slide upward along the inner wall of the slide groove two.

[0012] Preferably, the sliding assembly includes a piston slidably connected to the inner wall of the second slide groove, a hollow column is fixedly connected to the top of the piston, and a sealing plate is fixedly connected to the end of the hollow column away from the piston. The sliding square plate has a flow hole at its center, and the sliding component can slide up and down along the inner wall of the flow hole. When the piston is pressed and slides upward, the high-pressure air will be discharged upward through the gap between the hollow column and the flow hole. In addition, under normal conditions, the top of the sealing plate is flush with the top of the sliding square plate.

[0013] Preferably, the circulation component includes an air circulation groove formed in the inner wall of the metal rod; In normal operation, the piston will block the bottom port of the air circulation channel. As the piston moves upward, some air will be transmitted to the top of the piston through the air circulation channel and discharged upward through the gap between the hollow column, the sealing plate and the circulation port.

[0014] The present invention has the following beneficial effects: (1) The present invention utilizes the feature of pressing the top of the sliding square plate by the pressing plate. A pressure component is provided inside the device. Sufficient gas is injected into the slide groove two through the air inlet pipe. The gas will be injected between the sliding square plate and the thin sheet through the moving mechanism, so that there is an air bulge between the thin sheet and the top of the sliding square plate. As the air intake increases, the bulge will spread around. Since the thin sheet is pressed around by the sliding plate, the flow resistance in the pressed area is greater than that in other positions. This makes it impossible for the edge of the bulge to continue to expand outward after reaching the edge of the pressing. Instead, the bulge will expand to other positions. Through the application of the above component, the problem of excessive adhesion area between the thin sheet and the sliding square plate is effectively prevented when the device is in use because the bulge expands outward from a single position.

[0015] (2) The present invention utilizes the feature of the sliding plate pressing the polyester particles first. Since the distance between the pressing plate and the sliding plate is fixed, if the worker puts less material into the top of the sliding plate, as the sliding plate is pressed down, the particles around the perimeter will move towards the center, increasing the material at the bottom of the pressing plate. As the pressing plate melts the polyester particles, if the melted material cannot completely fill the gap between the pressing plate and the sliding plate, the spring will push the sliding plate downward to supply the melted material at the bottom of the sliding plate to the center, ensuring that the thickness of the finished product is uniform at the center. In addition, if there is too much material between the pressing plate and the sliding plate, the downward pressing force of the pressing plate will force the excess melted material to concentrate at the bottom of the sliding plate. After demolding, the worker cuts the edge of the sheet. Through the application of the above components, the uniform thickness of the polyester sheet is effectively ensured.

[0016] (3) The present invention utilizes the characteristic of the gas being discharged into the interior through the inlet pipe and sets up a sliding component inside the device. As the gas entering the second slide increases, the gas pressure will force the piston to slide upward along the inner wall of the second slide. The upward-moving piston drives the sealing plate to move upward synchronously through the hollow column, so that the sealing plate will push the top thin plate upward first. When the sealing plate moves upward, the gas inside the second slide will also be discharged upward. Through the design of the sealing plate prioritizing the lifting of the thin plate, a circular expansion space is formed in advance for the bottom of the thin plate. Since the gas pressure inside the "circular bulge" will provide uniform pressure to the surrounding area, when the gas is replenished into the "circular bulge" later, the "circular bulge" will spread evenly to the surrounding area. Through the above component design, it is effectively ensured that the bulge will spread evenly from the center to the surrounding area, preventing the bulge from expanding in one direction, causing the pressure at the expansion end to exceed the pressing force of the sliding plate, resulting in the problem of bulge leakage.

[0017] (4) The present invention utilizes the characteristic of the high-pressure gas pushing the piston to move upward. An air circulation groove is provided inside the equipment. When the high-pressure gas pushes the piston to move upward, the piston will release the blockage of the air circulation groove, so that the high-pressure gas at the bottom of the slide groove II flows upward through the air circulation groove, causing the air pressure at the bottom of the piston to drop. At this time, the spring I will pull the piston down again and block the bottom hole of the air circulation groove again. When the air pressure at the bottom of the piston increases again, the piston will move upward again. Through the design of the piston sliding up and down, each time the sealing plate moves up, the bulge will expand again. In addition, the reciprocating sliding of the sealing plate will accelerate the demolding speed of the thin sheet at the top of the sealing plate. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1, please refer to Figures 1-8 This invention relates to a recycled polyester sheet-making device, comprising a support 13, a fixing frame 14 fixedly connected to the top of the support 13, an electric actuator 15 fixedly connected to the end of the fixing frame 14 away from the support 13, a heater 16 fixedly connected to the output end of the electric actuator 15, and a pressing plate 17 fixedly connected to the bottom of the heater 16, and further comprising: Restriction mechanism 1 is fixedly installed on the top of bracket 13; Auxiliary mechanism 2 is fixedly installed on the inner wall of bracket 13; The moving mechanism 3 is slidably disposed on the inner wall of the auxiliary mechanism 2. During use, the electric push rod 15 pushes the heater 16 and the pressing plate 17 downward to press down, completing the basic pressing process.

[0023] Restricted agency 1 includes: Fixing component 11 is fixedly mounted on the top of bracket 13; Pressure application component 12 is slidably disposed on the outer wall of pressure plate 17; Before use, workers need to put polyester granules into the inner wall of the fixing component 11, and then the electric push rod 15 pushes the pressing plate 17 downward to press it down.

[0024] Auxiliary mechanism 2 includes: Power assembly 21 is fixedly installed on the inner wall of bracket 13; The air intake assembly 22 is fixedly mounted on the top end of the power assembly 21; After the equipment completes the basic pressing process, the power component 21 pushes the fixed component 11 to move upward and performs the basic demolding process.

[0025] Mobile mechanism 3 includes: Sliding component 31 is slidably disposed on the inner wall of intake component 22; The flow component 32 is located on the inner wall of the power component 21; The high-pressure gas from the outside enters the inner wall of the power assembly 21 through the air intake assembly 22, and is then transmitted to the gap between the finished product and the fixed assembly 11 through the flow assembly 32 and the sliding assembly 31.

[0026] Example 2, please refer to Figures 2-10 The present invention is a recycled polyester sheet making equipment. Based on the first embodiment, the fixing component 11 includes a fixing plate 111 fixedly connected to the top of the support 13. A through hole groove 112 is opened at the top center of the fixing plate 111, and a sliding square plate 113 is slidably connected to the inner wall of the through hole groove 112. Before use, place the equipment in the desired position, then connect the power supply and preheat the pressing plate 17 through the heater 16. Then, the operator sprays the release agent on the top of the through-hole groove 112 and the sliding square plate 113, and then puts a sufficient amount of polyester granules on the top of the sliding square plate 113. After ensuring that the material on the top of the sliding square plate 113 is flat, the electric push rod 15 drives the pressing plate 17 to slide downward through the heater 16. The pressing plate 17 will press the material on the top of the sliding square plate 113. Under the influence of high temperature, the polyester granules gradually melt and form a thin sheet. Then, the electric push rod 15 drives the pressing plate 17 to move upward, and the air intake component 22 slowly injects high-pressure gas into the gap between the finished product and the sliding square plate 113 through the moving mechanism 3 to complete the demolding of the thin sheet.

[0027] The pressure application component 12 includes a slide groove 121 on both sides of the pressing plate 17, a sliding plate 122 is slidably connected to the inner wall of the slide groove 121, and a spring 123 is fixedly connected to the top of the sliding plate 122. Utilizing the characteristic of the sliding plate 122 to first press the polyester granules, since the distance that the electric actuator 15 drives the pressing plate 17 to move downward is fixed, the distance between the pressing plate 17 and the sliding square plate 113 remains constant during pressing. If the worker puts less material into the top of the sliding square plate 113, as the sliding plate 122 presses down, the granules around the edges will move towards the center, increasing the material at the bottom of the pressing plate 17. Furthermore, as the pressing plate 17 melts the polyester granules, if the melted material cannot completely fill the pressing plate... When there is a gap between the pressing plate 17 and the sliding square plate 113, the spring 123 will push the sliding plate 122 downward, supplying the molten material at the bottom of the sliding plate 122 towards the center, ensuring that the thickness of the finished product is uniform at the center position; in addition, if there is too much material between the pressing plate 17 and the sliding square plate 113, the downward pressing force of the pressing plate 17 will force the excess molten material to concentrate at the bottom of the sliding plate 122. After demolding is completed, the workers will cut the edges of the sheet. Through the application of the above components, the uniform thickness of the polyester sheet is effectively ensured.

[0028] The power assembly 21 includes a fixing plate 211 fixedly connected to the inner wall of the bracket 13, an electric actuator 212 fixedly connected to the top of the fixing plate 211, and a metal rod 213 fixedly connected to the output end of the electric actuator 212. The end of the metal rod 213 away from the electric push rod 212 is fixedly connected to the bottom of the sliding square plate 113. After the equipment completes the pressing, as the electric push rod 15 drives the pressing plate 17 to move upward, the electric push rod 212 pushes the metal rod 213 to move upward in sync.

[0029] The air intake assembly 22 includes a groove 221 opened at the end of the metal rod 213 away from the electric push rod 212. An air intake pipe 222 is connected through the top of the side wall of the metal rod 213. A spring 223 is fixedly connected to the inner wall of the groove 221. Utilizing the characteristic of the pressing plate 17 pressing the top of the sliding square plate 113, a pressure application component 12 is provided inside the equipment. As the pressing plate 17 moves downward, the sliding plate 122 slides downward simultaneously, first contacting the polyester particles on the top of the sliding square plate 113. As the top polyester particles melt into sheets, the particles contacting the bottom of the sliding plate 122 also become thin sheets. Subsequently, when the electric actuator 15 moves the pressing plate 17 upward, due to the pushing force of the spring 123, the sliding plate 122 remains in contact with the outer wall of the thin sheet. During this process, the air inlet pipe 222 injects sufficient gas into the slide groove 221. The gas is injected between the sliding square plate 113 and the sheet through the moving mechanism 3, creating an air bulge between the sheet and the top of the sliding square plate 113. As the air intake increases, the bulge expands outwards. Since the sheet is pressed down by the sliding plate 122, the flow resistance in the pressed area is greater than in other areas. This prevents the bulge from expanding outwards after reaching the pressed edge, and the bulge expands to other areas. Through the application of the above components, the problem of excessive adhesion area between the sheet and the sliding square plate 113 is effectively prevented when the bulge expands outwards from a single position during equipment use.

[0030] The sliding assembly 31 includes a piston 311 that is slidably connected to the inner wall of the slide groove 221. A hollow column 312 is fixedly connected to the top of the piston 311, and a sealing plate 313 is fixedly connected to the end of the hollow column 312 away from the piston 311. Taking advantage of the gas's inward discharge through the inlet pipe 222, a sliding assembly 31 is installed inside the device. As the gas entering the second slide groove 221 increases, the gas pressure forces the piston 311 to slide upward along the inner wall of the second slide groove 221. The upward-moving piston 311 drives the sealing plate 313 to move upward synchronously through the hollow column 312. This causes the sealing plate 313 to preferentially push the top sheet upward. As the sealing plate 313 moves upward, the gas inside the second slide groove 221 is also discharged upward. Through the design of the sealing plate 313 preferentially pushing up the sheet, a circular expansion space is formed at the bottom of the sheet in advance. Since the gas pressure inside the "bulge" will provide uniform pressure to the surrounding area, when gas is subsequently added to the "circular bulge", the "circular bulge" will diffuse evenly to the surrounding area. Through the above component design, it is effectively ensured that the bulge will diffuse evenly from the center to the surrounding area, preventing the bulge from expanding in one direction and causing the pressure at the expansion end to exceed the pressing force of the sliding plate 122, resulting in the bulge leaking out.

[0031] The circulation component 32 includes an air circulation groove 321 formed in the inner wall of the metal rod 213; Taking advantage of the high-pressure gas pushing the piston 311 upward, an air circulation groove 321 is provided inside the equipment. When the high-pressure gas pushes the piston 311 upward, the piston 311 will release the blockage of the air circulation groove 321, allowing the high-pressure gas at the bottom of the slide groove 221 to flow upward through the air circulation groove 321, causing the air pressure at the bottom of the piston 311 to drop. At this time, the spring 223 will pull the piston 311 downward again and block the bottom hole of the air circulation groove 321 again. When the air pressure at the bottom of the piston 311 increases again, the piston 311 will move upward again. Through the reciprocating up and down sliding design of the piston 311, the bulge will expand again each time the sealing plate 313 moves upward. In addition, the reciprocating sliding of the sealing plate 313 will accelerate the demolding speed of the thin sheet on the top of the sealing plate 313.

[0032] A specific application of this embodiment is as follows: Before use, the equipment is placed in the required position, and then the power is turned on to preheat the pressing plate 17 through the heater 16. Then, the operator sprays the release agent on the top of the through hole groove 112 and the sliding square plate 113, and then puts a sufficient amount of polyester granules on the top of the sliding square plate 113. After ensuring that the material on the top of the sliding square plate 113 is flat, the electric push rod 15 drives the pressing plate 17 to slide downward through the heater 16. The pressing plate 17 will press the material on the top of the sliding square plate 113. Under the influence of high temperature, the polyester granules gradually melt and form a thin sheet. Then, the electric push rod 15 drives the pressing plate 17 to move upward, and the air intake component 22 slowly injects high pressure gas into the gap between the finished product and the sliding square plate 113 through the moving mechanism 3 to complete the demolding of the thin sheet.

[0033] Utilizing the characteristic of the pressing plate 17 pressing the top of the sliding square plate 113, a pressure application component 12 is provided inside the equipment. As the pressing plate 17 moves downward, the sliding plate 122 slides downward simultaneously, first contacting the polyester particles on the top of the sliding square plate 113. As the top polyester particles melt into sheets, the particles contacting the bottom of the sliding plate 122 also become thin sheets. Subsequently, when the electric actuator 15 moves the pressing plate 17 upward, due to the pushing force of the spring 123, the sliding plate 122 remains in contact with the outer wall of the thin sheet. During this process, the air inlet pipe 222 injects sufficient gas into the slide groove 221. The gas is injected between the sliding square plate 113 and the sheet through the moving mechanism 3, creating an air bulge between the sheet and the top of the sliding square plate 113. As the air intake increases, the bulge expands outwards. Since the sheet is pressed down by the sliding plate 122, the flow resistance in the pressed area is greater than in other areas. This prevents the bulge from expanding outwards after reaching the pressed edge, and the bulge expands to other areas. Through the application of the above components, the problem of excessive adhesion area between the sheet and the sliding square plate 113 is effectively prevented when the bulge expands outwards from a single position during equipment use.

[0034] Utilizing the characteristic of the sliding plate 122 to first press the polyester granules, since the distance that the electric actuator 15 drives the pressing plate 17 to move downward is fixed, the distance between the pressing plate 17 and the sliding square plate 113 remains constant during pressing. If the worker puts less material into the top of the sliding square plate 113, as the sliding plate 122 presses down, the granules around the edges will move towards the center, increasing the material at the bottom of the pressing plate 17. Furthermore, as the pressing plate 17 melts the polyester granules, if the melted material cannot completely fill the pressing plate... When there is a gap between the pressing plate 17 and the sliding square plate 113, the spring 123 will push the sliding plate 122 downward, supplying the molten material at the bottom of the sliding plate 122 towards the center, ensuring that the thickness of the finished product is uniform at the center position; in addition, if there is too much material between the pressing plate 17 and the sliding square plate 113, the downward pressing force of the pressing plate 17 will force the excess molten material to concentrate at the bottom of the sliding plate 122. After demolding is completed, the workers will cut the edges of the sheet. Through the application of the above components, the uniform thickness of the polyester sheet is effectively ensured.

[0035] Taking advantage of the gas's inward discharge through the inlet pipe 222, a sliding assembly 31 is installed inside the device. As the gas entering the second slide groove 221 increases, the gas pressure forces the piston 311 to slide upward along the inner wall of the second slide groove 221. The upward-moving piston 311 drives the sealing plate 313 to move upward synchronously through the hollow column 312. This causes the sealing plate 313 to preferentially push the top sheet upward. As the sealing plate 313 moves upward, the gas inside the second slide groove 221 is also discharged upward. Through the design of the sealing plate 313 preferentially pushing up the sheet, a circular expansion space is formed at the bottom of the sheet in advance. Since the gas pressure inside the "bulge" will provide uniform pressure to the surrounding area, when gas is subsequently added to the "circular bulge", the "circular bulge" will diffuse evenly to the surrounding area. Through the above component design, it is effectively ensured that the bulge will diffuse evenly from the center to the surrounding area, preventing the bulge from expanding in one direction and causing the pressure at the expansion end to exceed the pressing force of the sliding plate 122, resulting in the bulge leaking out.

[0036] Taking advantage of the high-pressure gas pushing the piston 311 upward, an air circulation groove 321 is provided inside the equipment. When the high-pressure gas pushes the piston 311 upward, the piston 311 will release the blockage of the air circulation groove 321, allowing the high-pressure gas at the bottom of the slide groove 221 to flow upward through the air circulation groove 321, causing the air pressure at the bottom of the piston 311 to drop. At this time, the spring 223 will pull the piston 311 downward again and block the bottom hole of the air circulation groove 321 again. When the air pressure at the bottom of the piston 311 increases again, the piston 311 will move upward again. Through the reciprocating up and down sliding design of the piston 311, the bulge will expand again each time the sealing plate 313 moves upward. In addition, the reciprocating sliding of the sealing plate 313 will accelerate the demolding speed of the thin sheet at the top of the sealing plate 313. As the pressing plate 17 continues to move upward, the electric push rod 212 drives the sliding square plate 113 to continue moving upward through the metal rod 213. Finally, the top of the sliding square plate 113 drives the sheet to disengage from the through hole groove 112 and stops moving. The electric push rod 15 drives the pressing plate 17 to move upward. Finally, the worker uses a tool to peel the sheet outward to complete the single processing. Subsequently, the electric actuator 212 drives the sliding square plate 113 back to the inner wall of the through hole groove 112 via the metal rod 213, and enters the standby state.
