Description

Technical Field

[0001] This utility model relates to the field of polyester chip technology, specifically to a polyester chip shaping device. Background Technology

[0002] Polyester chips are polymers formed by the chemical reaction of terephthalic acid and ethylene glycol. Polyester chips are chemically stable at room temperature and are not easily affected by acids, alkalis, salts, or other chemicals. They can be used at relatively high temperatures and have good heat resistance. Polyester chips have a wide range of applications, primarily in the manufacture of polyester fibers, polyester films, and polyester plastics. Polyester fiber is one of the main application areas for polyester chips, widely used in textiles, clothing, and household goods.

[0003] Polyester chip shaping refers to the process of treating polyester chips under specific temperature, pressure, and time conditions to form products with a certain shape and size. In this process, the polyester chips are first heated to a certain temperature until they reach a molten state. Then, they are pressed into the desired shape and size using molds or other molding equipment. Finally, the product is cooled to room temperature to solidify. There are many methods for polyester chip shaping, including injection molding, extrusion molding, and blow molding. Different molding methods are suitable for different products and production requirements.

[0004] In the process of realizing this utility model, the inventors discovered the following problems with the prior art: 1. After the existing shaping device extrudes the polyester melt to form filaments, the polyester fibers are prone to entanglement during the cooling process, which affects subsequent processing operations; 2. During the shaping of polyester chips, the overall cooling temperature of the existing shaping device is difficult to adjust precisely, which can easily cause uneven cooling and affect product quality. Utility Model Content

[0005] The purpose of this utility model is to provide a polyester chip shaping device to solve the problems mentioned in the background art, where existing shaping devices, after extruding polyester melt into filamentous fibers, tend to have the polyester fibers entangled during cooling, affecting subsequent processing operations. Furthermore, existing shaping devices struggle to precisely adjust the overall cooling temperature during polyester chip shaping, leading to uneven cooling and impacting product quality. To achieve the above objective, this utility model provides the following technical solution: a polyester chip shaping device, including a stirring mechanism. The bottom end of the stirring mechanism vertically penetrates the middle of the top of a heating furnace. The bottom end of the heating furnace is provided with a connecting pipe, and the bottom wall of the connecting pipe is provided with a conveying mechanism. One side of the connecting pipe is provided with a liquid injection pipe, the bottom end of which vertically penetrates one side of the top of an extrusion chamber. One side of the outer wall of the extrusion chamber is transversely permeated by a pushing mechanism, and the other side of the outer wall of the extrusion chamber is provided with several extrusion heads. The extrusion ends of the extrusion heads transversely penetrate one side of a cooling box, and one side of the outer wall of the cooling box is provided with a spraying mechanism. A feed inlet is located on one side of the top of the heating furnace.

[0006] More preferably, the stirring mechanism includes a first motor, a stirring shaft, and stirring blades. The output end of the first motor is inserted into the top end of the stirring shaft, the bottom end of the stirring shaft penetrates vertically through the middle of the top of the heating furnace, and a plurality of stirring blades are sleeved on the outer wall of the stirring shaft.

[0007] More preferably, a temperature sensor is vertically inserted through the other side of the top of the heating furnace, and several electric heating tubes are provided in the inner wall interlayer of the heating furnace.

[0008] More preferably, the conveying mechanism includes a second motor and a spiral conveying rod, the bottom of the second motor is screwed to the bottom wall of the connecting pipe, and the output end of the second motor is inserted into the spiral conveying rod.

[0009] More preferably, the extrusion mechanism includes a hydraulic cylinder and a push plate. The driving end of the hydraulic cylinder extends laterally through one side of the outer wall of the extrusion chamber, and the push plate is disposed at the driving end of the hydraulic cylinder, forming a sliding connection with the extrusion chamber.

[0010] More preferably, the spraying mechanism includes a water pump, a water pumping pipe, a water inlet pipe, and spray heads. One end of the water pumping pipe is inserted into one side of the cooling tank, and the other end of the water pumping pipe is inserted into the water pumping pipe. The top of the water pumping pipe is inserted into the water inlet pipe, and the bottom of the water inlet pipe is provided with several spray heads.

[0011] More preferably, the inner wall of the cooling box is equipped with a semiconductor cooling chip.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] In this invention, the spray head evenly sprays cooling water in the form of fine droplets onto the polyester fibers in the cooling box, increasing the contact area between the cooling water and the fibers and improving the heat exchange efficiency, thereby reducing the temperature of the polyester fibers more quickly. At the same time, during the cooling process, the polyester fibers may become entangled due to mutual friction, and the impact force of the spray water can help break up these entanglements, making the fibers fluffy and uniform again, which is conducive to the subsequent processing and treatment of the polyester fibers.

[0014] In this invention, the semiconductor cooling chip can cool the water in the cooling box to a lower temperature in a short time. This allows the polyester melt to quickly come into contact with the low-temperature cooling water after extrusion, achieving rapid cooling and shaping, improving production efficiency. Furthermore, the semiconductor cooling chip can precisely adjust the water temperature in the cooling box as needed. By controlling the magnitude and direction of the current, precise temperature control can be achieved, ensuring that the polyester fiber remains within the ideal temperature range during the cooling process, thereby guaranteeing stable product quality.

Detailed Implementation

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

[0022] Please see Figures 1 to 5 This utility model provides a technical solution: a polyester chip shaping device, including a stirring mechanism 1, the bottom end of which is vertically inserted through the middle of the top of a heating furnace 2, a connecting pipe 3 at the bottom end of the heating furnace 2, a conveying mechanism 4 on the bottom wall of the connecting pipe 3, a liquid injection pipe 5 on one side of the connecting pipe 3, the bottom end of the liquid injection pipe 5 being vertically inserted through the top side of an extrusion chamber 6, a pushing mechanism 7 being transversely inserted through the outer wall of one side of the extrusion chamber 6, a plurality of extrusion heads 8 on the outer wall of the other side of the extrusion chamber 6, the extrusion ends of the extrusion heads 8 being transversely inserted through one side of a cooling box 9, a spraying mechanism 10 being provided on the outer wall of one side of the cooling box 9, and a feed inlet 11 being provided on the top side of the heating furnace 2.

[0023] In this embodiment, as Figure 2 and Figure 3 As shown, the stirring mechanism 1 includes a first motor 101, a stirring shaft 102, and stirring blades 103. The output end of the first motor 101 is inserted into the top of the stirring shaft 102. The bottom end of the stirring shaft 102 vertically penetrates the middle of the top of the heating furnace 2. Several stirring blades 103 are sleeved on the outer wall of the stirring shaft 102. It should be noted that the operator can first put the polyester chips into the heating furnace 2 through the feed inlet 11 and then heat them. At the same time, the first motor 101 is started to drive the stirring shaft 102, which is inserted with it, to start rotating. This causes the stirring blades 103 sleeved on the outer wall of the stirring shaft 102 to rotate synchronously. During the heating process, the constantly rotating stirring blades 103 will drive the polyester chips to fully rotate. The stirring blades 103 contact the inner wall of the heating furnace 2 and are stirred and mixed until the polyester chips melt into a liquid state. In actual use, the rotation of the stirring blades 103 can make the polyester chips fully contact the inner wall of the heating furnace 2, ensuring uniform heat transfer and accelerating the melting speed. The stirring operation of the stirring mechanism 1 can prevent local overheating of the polyester chips during the heating process, thereby ensuring the stability of product quality. At the same time, continuous stirring can prevent the polyester chips from scorching during the heating process and ensure that the crystal particles generated during the heating of the polyester chips can be fully mixed, further ensuring the smooth progress of the production process. The drive of the first motor 101 makes the stirring intensity easy to control and can be adjusted according to production needs.

[0024] In this embodiment, as Figure 1 and Figure 3As shown, a temperature sensor 201 is vertically inserted through the top of the heating furnace 2 on the other side. Several electric heating tubes 202 are installed in the inner wall interlayer of the heating furnace 2. It should be noted that when the operator pours polyester chips into the heating furnace 2 through the feed inlet 11, the first motor 101 and the electric heating tubes 202 can be started simultaneously. At the same time, the electric heating tubes 202 will begin to heat the inner wall of the heating furnace 2, causing the internal temperature of the heating furnace 2 to rise. Then, with the cooperation of the stirring mechanism 1, the polyester chips inside melt into a liquid state. During this period, the temperature sensor 201 will monitor the internal temperature of the heating furnace 2 in real time. The specific temperature is fed back to the external controller for control and adjustment. In actual use, the electric heating tubes 202 are evenly distributed in the inner wall interlayer of the heating furnace 2, which can stably provide heat and keep the internal temperature of the heating furnace 2 uniform, avoiding local overheating or temperature fluctuations. This allows for stable heating when in contact with polyester chips. The temperature sensor 201 can accurately control the heating temperature of the electric heating tubes 202 through real-time monitoring and feedback, ensuring that the polyester chips melt at the appropriate temperature. This helps to ensure the quality of the polyester chips and reduce product performance differences caused by improper temperature.

[0025] In this embodiment, as Figure 3 As shown, the conveying mechanism 4 includes a second motor 401 and a spiral conveying rod 402. The bottom of the second motor 401 is screwed to the bottom wall of the connecting pipe 3, and the output end of the second motor 401 is inserted into the spiral conveying rod 402. It should be noted that after the polyester chips are melted into a molten state, the operator can open the solenoid valve at the connecting pipe 3, allowing the molten polyester to flow downward into the interior of the connecting pipe 3. At the same time, the second motor 401 is started to drive the spiral conveying rod 402 inserted therein to begin rotating. During this process, the rotating spiral conveying rod 402 will push the molten polyester that has entered the interior of the connecting pipe 3 downward, allowing it to flow smoothly into the injection pipe provided on one side of the connecting pipe 3. In step 5, the liquid is pushed into the extrusion chamber 6 through the injection pipe 5 for subsequent operations. In actual use, the rotation of the spiral conveyor rod 402 can generate a strong driving force, enabling the polyester melt to flow quickly and smoothly inside the connecting pipe 3, thereby improving the conveying efficiency. Moreover, the spiral structure of the spiral conveyor rod 402 can make the polyester melt be uniformly squeezed and pushed during the conveying process, avoiding local accumulation or uneven flow, thereby ensuring the stability of product quality. At the same time, by controlling the speed of the second motor 401, the rotation speed of the spiral conveyor rod 402 can be adjusted, thereby achieving precise control of the polyester melt conveying amount to meet the needs of different production processes.

[0026] In this embodiment, as Figure 4As shown, the extrusion mechanism 7 includes a hydraulic cylinder 701 and a pusher plate 702. The driving end of the hydraulic cylinder 701 extends laterally through one side of the outer wall of the extrusion chamber 6. The pusher plate 702 is located at the driving end of the hydraulic cylinder 701, and the pusher plate 702 is slidably connected to the extrusion chamber 6. It should be noted that after the molten polyester melt enters the extrusion chamber 6, the operator can activate the hydraulic cylinder 701 to extend its driving end laterally and drive the pusher plate 702 connected to it to move laterally together. During this process, the pusher plate 702 will slide laterally against the inner wall of the extrusion chamber 6, thereby continuously pushing the molten polyester melt inside the extrusion chamber 6 toward the extrusion head 8 on the other side. Approaching until the polyester melt is rapidly squeezed into the extrusion head 8 and simultaneously extruded outwards, in actual use, the hydraulic cylinder 701 can provide precise linear motion. By controlling the stroke and pressure of the hydraulic cylinder 701, the displacement and pushing force of the push plate 702 can be precisely controlled, so that the polyester melt can be quickly and smoothly squeezed into the extrusion head 8, avoiding fluctuations or unevenness of the polyester melt during the extrusion process. Moreover, by adjusting the parameters of the hydraulic cylinder 701, it can adapt to different production needs, thereby accurately controlling the extrusion amount and speed of the polyester melt, so that the polyester melt can form more uniform fine fiber.

[0027] In this embodiment, as Figure 5As shown, the spraying mechanism 10 includes a water pump 1001, a water pumping pipe 1002, a water inlet pipe 1003, and spray heads 1004. One end of the water pumping pipe 1002 is inserted into one side of the cooling tank 9, and the other end of the water pumping pipe 1002 is inserted into the water pump 1001. The top of the water pump 1001 is connected to the water inlet pipe 1003, and the bottom of the water inlet pipe 1003 is provided with several spray heads 1004. It should be noted that when the polyester melts... The liquid is extruded from the extrusion head 8 and forms a fine stream. Under gravity, the stream directly enters the cooling tank 9, which is connected to the extrusion head 8, and comes into contact with the cooling water inside. There, it cools and solidifies to form fibers. Simultaneously, the operator can activate the water pump 1001 to draw cooling water from inside the cooling tank 9 through the connected water pipe 1002, and push the cooling water along the water inlet pipe 1003 through several spray heads 1004. Then, the water sprays downwards through the nozzles at the bottom of the spray head 1004, coming into contact with the polyester fibers in the cooling water. This further cools the fibers and simultaneously breaks up any tangled strands. In actual use, the spray head 1004 sprays cooling water evenly onto the polyester fibers in the cooling box 9 in the form of fine droplets, increasing the contact area between the cooling water and the fibers, improving heat exchange efficiency, and thus lowering the temperature of the polyester fibers more quickly. Furthermore, due to the uniform distribution of the spray heads 1004, the cooling water can fully cover the polyester fibers, avoiding localized overcooling and helping to maintain fiber quality consistency, improving product stability and reliability. Simultaneously, during the cooling process, the polyester fibers may become tangled due to mutual friction; the impact force of the spray water helps to break up these tangles, making the fibers fluffy and uniform again, thus facilitating subsequent processing and treatment of the polyester fibers.

[0028] In this embodiment, as Figure 5As shown, a semiconductor cooling chip 901 is installed on the inner wall of the cooling box 9. It should be noted that when the operator begins to use the pushing mechanism 7 to push the polyester melt inside the extrusion chamber 6, the operator can activate the semiconductor cooling chip 901. This allows the semiconductor cooling chip 901 to cool the water filling the cooling box 9, converting it into lower-temperature cooling water. When the polyester melt is ejected from the extrusion head 8, the resulting stream falls directly into the cooling box 9 and comes into contact with the cooling water, thus rapidly cooling and shaping it into polyester fibers. In practical use, the semiconductor cooling chip 901 can cool the water in the cooling box 9 to a lower temperature in a short time. This allows the polyester melt to quickly come into contact with the low-temperature cooling water after extrusion, achieving rapid cooling and shaping, improving production efficiency. Furthermore, the semiconductor cooling chip 901 can precisely adjust the water temperature in the cooling box 9 as needed. By controlling the magnitude and direction of the current, precise temperature control can be achieved, ensuring that the polyester fibers remain within the ideal temperature range during the cooling process, thereby guaranteeing product quality stability.

[0029] The method of use and advantages of this utility model: The working process of this polyester chip shaping device is as follows:

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the operator first places the polyester chips into the heating furnace 2 through the feed inlet 11. Simultaneously, the first motor 101 and the electric heating element 202 are started. At the same time, the electric heating element 202 begins to heat the inner wall of the heating furnace 2, raising the internal temperature. Then, the first motor 101 is started, driving the connected stirring shaft 102 to rotate. This causes the stirring blades 103, which are fitted onto the outer wall of the stirring shaft 102, to rotate synchronously. During heating, the continuously rotating stirring blades 103 ensure that the polyester chips fully contact and mix with the inner wall of the heating furnace 2 until the polyester chips melt. During the process of melting the polyester chips into a liquid state, the temperature sensor 201 monitors the specific temperature inside the heating furnace 2 in real time and feeds it back to the external controller for control and adjustment. After the polyester chips are melted into a molten state, the operator can open the solenoid valve at the connecting pipe 3, allowing the molten polyester to flow downward into the interior of the connecting pipe 3. At the same time, the second motor 401 is started to drive the screw conveyor 402 connected to it to start rotating. During this process, the rotating screw conveyor 402 pushes the molten polyester that has entered the interior of the connecting pipe 3 downward, allowing it to flow smoothly into the injection pipe 5 provided on one side of the connecting pipe 3, and then flow along the injection pipe... 5. The melt is pushed into the extrusion chamber 6. Simultaneously, the hydraulic cylinder 701 can be activated to extend its drive end laterally, causing the connected push plate 702 to move laterally as well. During this process, the push plate 702 will slide laterally against the inner wall of the extrusion chamber 6, thereby continuously pushing the polyester melt inside the extrusion chamber 6 towards the extrusion head 8 on the other side. At the same time, the operator can activate the semiconductor cooling chip 901 to cool the water filled inside the cooling tank 9, turning it into cooler water. When the polyester melt is quickly squeezed into the extrusion head 8 and extruded outwards... After forming a fine stream, the stream will directly enter the cooling box 9 connected to the extrusion head 8 under the action of gravity, and come into contact with the cooling water inside, thereby cooling and solidifying to form fiber filaments. At the same time, the operator can start the water pump 1001 to draw the cooling water inside the cooling box 9 through the water pump pipe 1002 connected to it, and push the cooling water along the water inlet pipe 1003 through several spray heads 1004, and then spray it downwards through the spray holes at the bottom of the spray head 1004, thereby coming into contact with the polyester fibers in the cooling water, further cooling them and breaking up the tangled polyester fibers at the same time.
