Description

Technical Field

[0001] The invention relates to the technical field of polyester chip raw material pretreatment, in particular to polyester chip raw material pretreatment equipment. Background Art

[0002] Pre-crystallization and drying of polyester chips (such as PET) are key steps before processing to ensure material performance and processing stability, prevent adhesion and agglomeration during drying, and continue melt processing after stabilization; depending on the equipment and chip characteristics, the operating temperature is usually between 150-170°C and the time is 15-60 minutes. During the process, external forces such as stirring are applied to prevent particles from sticking together, while removing moisture and maintaining material strength and transparency.

[0003] Chinese patent CN210590052U discloses a polyester chip crystallization drying device; by fixing the crystallization bed obliquely on the upper part of the shaking table, the polyester chips enter the crystallization bed through the feed hopper, and hot air is blown into the crystallization bed through the air inlet pipe, so that the polyester chips are crystallized and dried in the crystallization bed.

[0004] However, this technical solution uses the polyester chips' own gravity to fall and impact when separating them, thereby separating the polyester chips that are stuck to each other. However, due to the light weight of the polyester chips, the force generated is sometimes not enough to separate them. In addition, powder is generated during the impact process. These powders may adhere to the polyester chips more tightly under the impact and extrusion of the polyester chips, and are difficult to be removed by wind and vibration, thereby affecting the subsequent pre-crystallization work of the polyester chips and the quality of the polyester chips themselves. Summary of the invention

[0005] The purpose of the present invention is to address the shortcomings of the prior art and provide a polyester chip raw material pretreatment device, which can achieve the functions of complete separation of polyester chips and removal of powder on the surface of polyester chips by setting a processing mechanism in conjunction with a drying mechanism, thereby solving the problems of inability to completely separate the chips by falling impact due to their own weight and inability to effectively separate the chips due to powder adhesion.

[0006] To achieve the above object, the present invention provides the following technical solution: a polyester chip raw material pretreatment device, comprising:

[0013] The kneading assembly includes two groups of rollers connected to the hollow discs and two groups of sponge belts wound around the rollers and passing through the hollow discs;

[0014] The negative pressure component includes an installation box connected to the hollow disc and sleeved on the sponge belt, a second motor connected to the installation box and having an output end connected to the first conveying roller, a fan blade connected to the first conveying roller, and a collection box connected to the hollow disc and connected to the installation box.

[0015] The cleaning assembly includes a carrying plate connected to the mounting box, a second conveying roller connected to the carrying plate and having half gears connected at both ends, a transmission ring connected to the second conveying roller and used to cooperate with the first conveying roller for transmission, a knocking plate connected to the carrying plate through a third telescopic member, a follower rack connected to both ends of the knocking plate and meshing with the half gears for transmission, a vertical rod connected to the processing box, and a lifting plate connected to the mounting box through a first rotating shaft.

[0016] The drying mechanism includes a polymerization component arranged on the heat preservation box and used to collect and transport the polyester chips one by one, a drying component arranged on the heat preservation box and used to dry and pre-crystallize the polyester chips, a turning component arranged on the drying component and used to turn the polyester chips 180 degrees, and a temperature control component arranged on the drying component and used to control the working temperature.

[0017] The polymerization component includes a door panel that passes through the insulation box and is connected to a triangular block through a fourth telescopic member, a columnar block connected to the insulation box through a second rotating shaft, an avoidance groove opened on the insulation box, an arc rod connected to the columnar block and located in the avoidance groove, a guide groove opened on the columnar block, a guide rod connected to the door panel and one end of which is located in the guide groove, a collecting groove connected to the insulation box and used for collecting polyester chips, and a driving rod connected to the output end of the first driving cylinder and used for driving the triangular block to move.

[0018] The drying component includes a third motor connected to the processing box and having an output end connected to the first tray, a second tray and a third tray connected to the output end of the third motor and arranged up and down, two groups of first drying channels and second drying channels connected to the insulation box and respectively located on the second tray and the third tray, a first connecting pipe arranged between the collecting tank and the first drying channel, and a second connecting pipe arranged between the first drying channel and the second drying channel.

[0019] The flip assembly includes a trigger rod respectively penetrating the first connecting tube and the second connecting tube, a spring connected to the trigger rod, and a plurality of extrusion blocks respectively connected to the bottom of the first tray and the second tray and used to drive the trigger rod to move;

[0020] The temperature control assembly includes a three-way pipe arranged at one end of the second drying channel and passing through the insulation box, a dryer arranged on the processing box and connected to the three-way pipe, and a temperature sensor arranged on the first drying channel and cooperating with the dryer to adjust the temperature.

[0021] The input mechanism comprises a vibration component which is arranged on the processing box and used for driving the toggle component to vibrate, and a pre-separation component which is arranged on the processing box and used for inputting polyester chips.

[0022] The vibration assembly includes a fourth motor connected to the processing box and having a cam connected to the output end, a feed pipe connected to the processing box, a spiral dragon connected to the feed pipe, and a belt transmission member whose two ends are respectively connected to the spiral dragon and the output end of the fourth motor, and the cam is used to drive the insulation box to vibrate;

[0024] The beneficial effects of the present invention are:

[0025] (1) The present invention provides a kneading component in the processing mechanism. When only a small part of the polyester slices are adhered to each other, it is difficult to separate them by vibration and pushing due to their light weight. At this time, the convex pattern on the first tray is used to apply a blocking force to the polyester slices from below, and the friction force of the relative sliding of the sponge belt after being squeezed and deformed is combined with the interaction force to twist the two tightly adhered polyester slices apart, thereby completing the separation work.

[0026] (2) The present invention provides a rubbing component. After the sponge belt separates all the bonded polyester slices, its height is just at the top of the polyester slices. Then, during the rotation of the hollow disc, the sponge belt wipes the top of the polyester slices, cooperates with the negative pressure component to remove the powder, and then cooperates with the vibration component to vibrate and flip the polyester slices, thereby greatly reducing the residual powder.

[0027] (3) The present invention sets a toggle assembly in the processing mechanism. During the gradual falling of the hollow disc, the toggle plate interacts with the convex patterns on the first tray to gradually disperse the combined whole of more polyester chips and evenly disperse them to prevent stacking, so as to facilitate the kneading assembly to carry out targeted separation work and the separated polyester chips to evenly contact with the first tray, thereby cooperating with the temperature generated by the drying assembly to improve the preheating efficiency.

[0028] (4) The present invention arranges the polyester chips in a channel by setting a drying component in the drying mechanism, and dries them in a smaller space, which is conducive to consuming less energy and achieving maximum efficiency. After the space is reduced, it is easier to adjust the overall temperature to quickly adapt to the influence of different numbers and volumes of polyester chips and the external temperature.

[0029] In summary, the present invention has the advantages of high pre-crystallization degree, no powder on the slice surface and stable pre-crystallization drying effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] Embodiment 1

[0050] like Figures 1 to 4 and Fig.10 As shown, this embodiment provides a polyester chip raw material pretreatment device, which also includes:

[0051] A processing mechanism 1, which is disposed in a processing box 100 and is used to separate, clean and preheat the polyester chips 200;

[0052] A drying mechanism 2, which is disposed on the processing mechanism 1 and is used to transfer the polyester chips 200 and perform drying and pre-crystallization processing;

[0053] An input mechanism 3, which is arranged on the processing box 100 and is used to transport the polyester chips 200 to the processing mechanism 1 and perform even spreading and separation operations;

[0054] The processing mechanism 1 includes a toggle assembly 11 arranged on the processing box 100 and used to receive the polyester chips 200, a kneading assembly 12 arranged on the toggle assembly 11 and used to clean the polyester chips 200 and promote separation, a negative pressure assembly 13 arranged on the toggle assembly 11 and used to recover polyester powder, and a cleaning assembly 14 arranged on the negative pressure assembly 13 and used to help the kneading assembly 12 perform self-cleaning.

[0055] In this embodiment, the processing mechanism 1 cooperates with the drying mechanism 2 to achieve the functions of complete separation of the polyester chips 200 and removal of powder on the surface of the polyester chips 200, thereby solving the problems of inability to completely separate the chips by falling only by self-weight and inability to effectively separate the chips due to powder adhesion.

[0056] The pre-drying mechanism 4 includes: a centrifugal device 500, which is used to blow spirally rising hot air to drive the polyester chips 200 to move upward for output by using wind force on the one hand, and to evaporate moisture by using hot air flow during the movement on the other hand; an inlet pipe 300 connected to one side of the centrifugal device 500 and a drain pipe 400 connected to the inlet pipe 300, the inlet pipe 300 is used to transport the polyester chips 200 and cooling water into the centrifugal device 500 together, and separate the solid and liquid through the filter screen provided on the drain pipe 400; an exhaust pipe 600 connected to one side above the centrifugal device 500, the exhaust pipe 600 is used to guide the air flow output; a conduit 700 connected to one side of the top of the centrifugal device 500, the conduit 700 is used to collect the polyester chips 200 after moisture is dried and transport them to the input mechanism 3.

[0057] In detail, first, a large volume of polyester material is transported to a cooling pool for cooling and slitting. After the slitting of the polyester chips 200 is completed, smaller particles of raw materials are formed. These polyester chips 200 raw materials are transported to the centrifugal device 500 through the water inlet pipe 300 along with the water flow. The raw materials and water are separated by filtration before entering the centrifugal device 500. The cooling water is discharged through the drain pipe 400. Then, hot air is introduced into the centrifugal device 500. Under the action of wind, the polyester chips 200 gradually rotate upward from the bottom of the centrifugal device 500, complete their own moisture drying and output from the top conduit 700. Finally, the polyester chips 200 enter the processing mechanism 1 through the input mechanism 3, and the hot air is output from the exhaust pipe 600 at the top of the centrifugal device 500 for reheating and reuse.

[0058] In the processing mechanism 1, the polyester chips 200 are firstly separated as a whole by gradually moving the component 11 and evenly spread to all sides. In the second step, the polyester chips 200 that are closely combined with each other are separated by the kneading component 12 through the mutual force. In the third step, the kneading component 12 vibrates in coordination with the input mechanism 3, and the two are performed alternately to completely remove the powder on both sides of the polyester chips 200. Then the chips are sent to the drying mechanism 2 for drying and pre-crystallization.

[0059] It should be noted that since the specifications of the polyester chips 200 are flake particles of about 4×5×2 mm, during the separation process, the two sides with larger areas usually cover the powder on the first tray 113 downwards and are tightly combined with the powder under pressure and impact. Therefore, the kneading component 12 mainly targets these two sides when wiping the powder. The powder on the remaining surfaces is relatively loose because it is not squeezed much. The adsorption of the negative pressure component 13 during the vibration process can well remove the surface powder.

[0060] It should be noted that, through the rapid dehydration treatment of the pre-drying mechanism 4, firstly, the moisture on the polyester chips 200 is quickly evaporated, which is beneficial to reducing the working time of subsequent drying and pre-crystallization. Secondly, the binding ability of the surface-dried polyester chips 200 with powder is reduced, which is beneficial to the powder removal work of the processing mechanism 1, thereby ensuring the smoothness of the surface of the polyester chips 200.

[0061] Further, if Figure 3 to Figure 4 and Figure 6 to Figure 7 as well as Figures 10 to 12 As shown, the toggle assembly 11 includes an insulation box 112 connected to the processing box 100 through multiple groups of first telescopic parts 111, a first tray 113 connected to the insulation box 112, a convex pattern 114 arranged on the first tray 113, a column 115 connected to the center position of the first tray 113, a first driving cylinder 117 connected to the processing box 100 and having a first motor 116 arranged at the output end, a hollow disc 118 connected to the output end of the first motor 116, a collecting hole 110 opened on the hollow disc 118, and a toggle plate 1110 penetrating the hollow disc 118 through a second telescopic part 119.

[0062] In this embodiment, by setting up the toggle component 11, in the process of the hollow disc 118 gradually falling, the toggle plate 1110 interacts with the convex pattern 114 on the first tray 113 to gradually disperse the combined whole of more polyester chips 200 and disperse them evenly to prevent stacking, so as to facilitate the kneading component 12 to perform targeted separation work and the separated polyester chips 200 to be evenly contacted with the first tray 113, and cooperate with the temperature generated by the drying component 22 to improve the preheating efficiency.

[0063] In detail, when the polyester slice 200 falls from the input mechanism 3 onto the first tray 113 on the toggle assembly 11, the first motor 116 starts to drive the hollow disc 118 to rotate through the output end, and at the same time, the first driving cylinder 117 drives the hollow disc 118 to move downward through the output end. During the gradual movement, the toggle plate 1110 at the bottom of the hollow disc 118 begins to contact the polyester slice 200 combined with each other, pushing from one side, and at the same time, the bottom of the entire polyester slice 200 is affected by the convex pattern 114 on both sides. The polyester chips 200 as a whole begin to disintegrate and disperse into multiple small wholes, such as two-by-two combinations, or three-by-three combinations, etc. As the toggle plate 1110 continues to rotate and move downward, the larger polyester chips 200 as a whole complete the dispersion work and are evenly separated to all sides. When the hollow disc 118 moves to a certain position, the toggle plate 1110 begins to contact and squeeze the column 115, causing the toggle plate 1110 to shrink toward the inside of the hollow disc 118, and the second telescopic member 119 shrinks.

[0064] Further, if Figure 3 to Figure 4 and Figures 10 to 14 As shown, the kneading assembly 12 includes two groups of rollers 121 connected to the hollow disc 118 and two groups of sponge belts 122 wound around the rollers 121 and passing through the hollow disc 118;

[0065] The negative pressure assembly 13 includes an installation box 131 connected to the hollow disc 118 and sleeved on the sponge belt 122, a second motor 133 connected to the installation box 131 and having an output end connected to a first conveying roller 132, a fan blade 134 connected to the first conveying roller 132, and a collection box 135 connected to the hollow disc 118 and connected to the installation box 131.

[0066] In this embodiment, by setting the kneading component 12, when only a small part of the polyester slices 200 are adhered to each other, it is difficult to separate them by vibration and shaking due to their light weight. At this time, the convex pattern 114 on the first tray 113 is used to apply a blocking force to the polyester slices 200 from below, and the friction force of the relative sliding after the sponge belt 122 is squeezed and deformed, and the interaction force causes the two tightly adhered polyester slices 200 to be twisted apart, thereby completing the separation work;

[0067] After the sponge belt 122 separates all the bonded polyester chips 200, its height is just at the top of the polyester chips 200. Then, during the rotation of the hollow disc 118, the sponge belt 122 wipes the top of the polyester chips 200, cooperates with the negative pressure component 13 to remove the powder, and then cooperates with the vibration component 31 to vibrate and flip the polyester chips 200, thereby greatly reducing the residual powder.

[0068] In detail, when the toggle plate 1110 is retracted, the sponge belt 122 starts to move downward. At this time, since the polyester slice 200 is only bonded in a single layer or double layer, the sponge belt 122 is deformed to a certain extent under the resistance of the second layer of polyester slice 200. During the rotation process after deformation, the sponge belt 122 pushes the second layer of polyester slice 200, and cooperates with the convex pattern 114 to separate the two mutually bonded polyester slices 200 by rubbing. After multiple rotations of the sponge belt 122, the polyester slices 200 are all in the form of a single layer on the top of the first tray 113, and the polyester slices 200 are 00, the top powder is wiped and absorbed, and the negative pressure component 13 works simultaneously during the process, and the first conveying roller 132 and the fan blade 134 are driven to rotate by the second motor 133. At this time, the airflow inside the hollow disc 118 is led out to form a negative pressure state, and then the powder is guided and absorbed in the space between the hollow disc 118, the insulation box 112 and the first tray 113; after completing the first wiping of the polyester chips 200, the kneading component 12 is driven by the first driving cylinder 117 to reset to a certain height and wait, and under the action of the input mechanism 3, the polyester chips 200 are turned over by vibration, and then the kneading component 12 is used to wipe and absorb again.

[0069] It should be noted that the sponge belt 122 is composed of a belt and a sponge with porous properties. The final height to which the sponge belt 122 descends is just at the top position of the single-layer polyester chip 200, thereby pushing the superimposed second layer and wiping and adsorbing the powder on the top of the first layer; there is a certain gap between the hollow disc 118 and the insulation box 112, which is used to introduce air when the negative pressure component 13 is working, and a filter is provided in the collection box 135 for filtering powder in the gas.

[0070] Further, if Figure 3 to Figure 4 and Figure 13 to Figure 14 As shown, the cleaning assembly 14 includes a carrying plate 141 connected to the mounting box 131, a second conveying roller 143 connected to the carrying plate 141 and having half gears 142 at both ends respectively connected thereto, a transmission ring 144 connected to the second conveying roller 143 and used to cooperate with the first conveying roller 132 for transmission, a knocking plate 146 connected to the carrying plate 141 through a third telescopic member 145, a follower rack 147 connected to both ends of the knocking plate 146 and meshing with the half gear 142 for transmission, a vertical rod 148 connected to the processing box 100, and a lifting plate 1410 connected to the mounting box 131 through a first rotating shaft 149.

[0071] In this embodiment, the cleaning component 14 is provided to facilitate timely discharge of the powder adsorbed on the sponge belt 122, so as to achieve the best state during the next operation. In addition, the cleaning component is connected to the power of the negative pressure component 13, and only works with the negative pressure component 13 when resetting, so that when the negative pressure component 13 adsorbs the powder on the first tray 113, the cleaning component will not drive the sponge belt 122 to rotate and affect the position state of the polyester chips 200, but will be connected to the power of the negative pressure component 13 when resetting. The two work together to effectively prevent the powder shaken off the sponge belt 122 from escaping to other locations.

[0072] In detail, after the powder removal work of the polyester chips 200 is completed, the kneading assembly 12 begins to reset to the initial state under the drive of the first driving cylinder 117, and in the final state, the vertical rod 148 connected to the processing box 100 is inserted into the top of the installation box and squeezes a section of the lifting plate 1410. Under the action of the first rotating shaft 149, the other end of the lifting plate 1410 lifts the carrying plate 141. At this time, the transmission ring 144 on the second conveying roller 143 is pressed and contacted with the first conveying roller 132, and the transmission is mutually transmitted, and the first conveying roller 132 and the second conveying roller 143 are connected. The sponge belt 122 is clamped in cooperation. With the start of the second motor 133, the sponge belt 122 begins to move with the first conveying roller 132 and the second conveying roller 143. During the process, the second conveying roller 143 intermittently drives the follower rack 147 to move upward through the half gears 142 at both ends. When separated from it, the follower rack 147 and the knocking plate 146 are reset together under the drive of the third telescopic member 145. During the reciprocating process, the knocking plate 146 continuously knocks on the sponge belt 122, so that the powder adsorbed inside the sponge belt 122 is dispersed and collected under the action of the negative pressure component 13.

[0073] Further, if Figures 3 to 9 As shown, the drying mechanism 2 includes a polymerization component 21 arranged on the heat preservation box 112 and used to collect and transport the polyester chips 200 one by one, a drying component 22 arranged on the heat preservation box 112 and used to dry and pre-crystallize the polyester chips 200, a turning component 23 arranged on the drying component 22 and used to turn the polyester chips 200 180°, and a temperature control component 24 arranged on the drying component 22 and used to control the working temperature.

[0074] In this embodiment, by providing the polymerization component 21 and the turning component 23, the polyester chips 200 are neatly arranged at a certain distance when entering the drying component 22, thereby effectively preventing the polyester chips 200 from contacting each other and affecting the drying and pre-crystallization effects.

[0075] In detail, the dispersed polyester chips 200 are first collected in cooperation with the drying component 22 and the polymerization component 21, and then the first group of flipping components 23 cooperate with the polymerization component 21 to release the polyester chips 200 one by one into the drying component 22. When the drying component 22 is in position, the second group of flipping components 23 flips the polyester chips 200 180° in the middle, so that the pre-crystallization of the polyester chips 200 can be fully carried out. During the process, the temperature control component 24 controls the temperature inside the drying component 22.

[0076] Further, if Figure 3 to Figure 4 , Figure 7 , Fig.10 as well as Figure 15 to Figure 16 As shown, the polymerization component 21 includes a door panel 213 that passes through the insulation box 112 and is connected to the triangular block 212 through a fourth telescopic member 211, a columnar block 215 connected to the insulation box 112 through a second rotating shaft 214, an avoidance groove 216 opened on the insulation box 112, an arc rod 217 connected to the columnar block 215 and located in the avoidance groove 216, a guide groove 218 opened on the columnar block 215, a guide rod 219 connected to the door panel 213 and one end of which is located in the guide groove 218, a collecting groove 2110 connected to the insulation box 112 and used for collecting polyester chips 200, and a driving rod 2111 connected to the output end of the first driving cylinder 117 and used for driving the triangular block 212 to move.

[0077] In this embodiment, by setting the arc rod 217 in the polymerization component 21, the polyester chips 200 are guided and output in a centralized manner by the arc rod 217 when they move as the first tray 113 rotates driven by the drying component 22. At the same time, the operation of the polymerization component 21 is driven by the power of the toggle component 11, so that the two tasks are coordinated, which enhances the continuity of the work and saves the waste of power resources.

[0078] In detail, when the output end of the first driving cylinder 117 moves downward, the driving rod 2111 is also driven to move downward. During the movement, the driving rod 2111 squeezes the top of the triangular block 212. Since the door panel 213 is blocked downward, the fourth telescopic member 211 contracts and the driving rod 2111 passes over the triangular block 212. Then, as the hollow disc 118 is reset to a certain height upward, the driving rod 2111 squeezes the triangular block 212, and at this time, the triangular block 212 and the door panel 213 are driven to move upward together, thereby opening the gap in the insulation box 112. When the door panel 213 moves upward, the guide rod 219 located in the guide groove 218 drives the columnar block 215 to rotate a certain angle, thereby driving the arc rod to turn out from the avoidance groove 216. Under the guidance of the arc rod 217, the polyester chips 200 that rotate and move with the first tray 113 begin to move toward the collecting groove 2110.

[0079] It should be noted that there is a certain height difference between the arc rod 217 and the top of the first tray 113, which is used to avoid the convex pattern 114. At the same time, during the output of the polyester chips 200, the vibration component 31 in the input mechanism 3 will drive the entire structure to vibrate. Some squeezed and stacked polyester chips 200 will pass over the arc rod 217 and rotate again to the output position, thereby reducing the output pressure. The door panel 213 can drive itself and the arc rod 217 to reset by its own gravity.

[0080] Further, if Figures 6 to 8 As shown, the drying component 22 includes a third motor 221 connected to the processing box 100 and having an output end connected to the first tray 113, a second tray 222 and a third tray 223 connected to the output end of the third motor 221 and arranged up and down, two groups of first drying channels 224 and second drying channels 225 connected to the insulation box 112 and respectively located on the second tray 222 and the third tray 223, a first connecting pipe 226 arranged between the collecting tank 2110 and the first drying channel 224, and a second connecting pipe 227 arranged between the first drying channel 224 and the second drying channel 225.

[0081] In this embodiment, by setting up a drying component 22, the polyester chips 200 are first arranged in a channel and dried in a smaller space, which is conducive to consuming less energy and achieving maximum efficiency. After the space is reduced, it is easier to adjust the overall temperature to quickly adapt to the influence of different numbers and volumes of polyester chips 200 and the external temperature.

[0082] In detail, when the polymerization component 21 starts to prepare to output the polyester chips 200, the third motor 221 first drives the first tray 113 to rotate rapidly, so that the polyester chips 200 located on the top thereof move to the edge due to the centrifugal force, and then reduces the rotation speed, cooperates with the arc rod 217 in the polymerization component 21 to collect the polyester chips 200, and then under the action of the first group of flipping components 23, the polyester chips 200 enter the first drying channel 224 one by one from the first connecting tube 226, and driven by the friction of the second tray 222, the polyester chips 200 arrive at the second connecting tube 227 along the first drying channel 224, and are flipped 180° here by the action of the second group of flipping components 23, so that the bottom surface is facing up and evenly dried; finally, driven by the third tray 223, the polyester chips 200 pass through the second drying channel 225 and are output.

[0083] Further, if Figure 3 and Figures 6 to 9 as well as Fig.17As shown, the flip assembly 23 includes a trigger rod 231 that passes through the first connecting tube 226 and the second connecting tube 227, a spring 232 connected to the trigger rod 231, and a plurality of extrusion blocks 233 that are respectively connected to the bottom of the first tray 113 and the second tray 222 and are used to drive the trigger rod 231 to move;

[0084] The temperature control assembly 24 includes a three-way pipe 241 arranged at one end of the second drying channel 225 and passing through the insulation box 112, a dryer 242 arranged on the processing box 100 and connected to the three-way pipe 241, and a temperature sensor 243 arranged on the first drying channel 224 and cooperating with the dryer 242 to adjust the temperature.

[0085] It is worth mentioning here that through the two sets of flipping components 23, the polyester chips 200 are intermittently input into the drying component 22 to maintain a certain spacing and flipped over during the drying process, which greatly improves the stability of the pre-crystallization of the polyester chips 200 during drying and ensures production quality.

[0086] In detail, during the rotation of the first tray 113 and the second tray 222, a plurality of extrusion blocks 233 are driven to rotate. The extrusion blocks 233 are in the shape of a triangular column. The extrusion blocks 233 squeeze one end of the trigger rod 231 through the inclined interval, and then cooperate with the reset work of the spring 232, so that one end of the trigger rod 231 moves back and forth in the first connecting tube 226 and the second connecting tube 227, thereby pushing the polyester chips 200 to flip and transmit at intervals; during the drying process, the temperature sensor 243 located at the inlet position of the first drying channel 224 monitors the temperature inside the channel in real time. When the temperature drops, even if the flow rate and temperature of the hot air flow are increased to keep the drying temperature constant, the hot air is generated by the dryer 242 and enters the tail end of the second drying channel 225 through the three-way pipe 241, and then transported upward in sequence, and finally released into the interior of the heat preservation box 112, on the one hand to ensure the constant drying temperature, on the other hand for preheating the polyester chips 200.

[0087] It should be noted that the first tray 113 is relatively thin and has excellent thermal conductivity, which is beneficial to the preheating of the polyester chips 200; the other end of the three-way pipe 241 is used to output the polyester chips 200, and the output space is sealed, so that the hot air can only be transported upward through the three-way pipe 241; the first drying channel 224 and the second drying channel 225 are provided with balls at the bottom of the inclined position at the front end, which is beneficial to the transportation of the polyester chips, and the rear spiral part has no bottom surface, and the polyester chips are directly in contact with the second tray 222 and the third tray 223.

[0088] Further, if Figures 1 to 5As shown, the input mechanism 3 includes a vibration component 31 disposed on the processing box 100 and used to drive the shifting component 11 to vibrate, and a pre-separation component 32 disposed on the processing box 100 and used to input the polyester chips 200.

[0089] In this embodiment, the input mechanism 3 is configured to perform two sets of vibration separations through the vibration component 31 and the pre-separation component 32 when the polyester chips 200 are input, which helps to reduce the pressure of the subsequent separation work of the polyester chips 200.

[0090] In detail, first, the vibration component 31 drives the polyester chips 200 to be output, and drives the insulation box 112 and the first tray 113 to vibrate. During the falling process, the polyester chips 200 are broken up by the action of the pre-separation component 32 and then fall to the top of the first tray 113.

[0091] It should be noted that the output end of the third motor 221 is composed of an inner rod and a sleeve rod, the inner rod is connected to the main body of the third motor 221, the sleeve rod is slidably mounted on the inner rod, and the sleeve rod is fixedly connected to the first tray 113, the second tray 222, the third tray 223 and the insulation box 112, so that when the insulation box 112 vibrates, the third motor 221 will not be driven to vibrate.

[0092] Embodiment 2

[0093] like Figures 3 to 5 As shown, the components identical or corresponding to those in the first embodiment are marked with the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that:

[0094] like Figures 3 to 5 As shown, the vibration assembly 31 includes a fourth motor 312 connected to the processing box 100 and having a cam 311 connected to the output end, a feeding pipe 313 connected to the processing box 100, a spiral dragon 314 connected to the feeding pipe 313, and a belt transmission member 315 whose two ends are respectively connected to the spiral dragon 314 and the output end of the fourth motor 312, and the cam 311 is used to drive the insulation box 112 to vibrate;

[0095] The pre-separation component 32 includes a swing plate 322 connected to the feed pipe 313 through a swing rod 321, a first gear 323 connected to the swing rod 321, and a first rack 324 connected to the feed pipe 313 and meshing with the first gear 323. One end of the first rack 324 cooperates with the cam 311 to drive the first gear 323 to rotate.

[0096] In this embodiment, by setting a cam 311 connected to the fourth motor 312, in the process of driving the polyester chips 200 to be input into the processing mechanism 1, the cam 311 simultaneously drives the insulation box 112 and the first tray 113 to vibrate and the swing plate 322 to swing to disperse the polyester chips 200, thereby accelerating the dispersion efficiency.

[0097] In detail, when the fourth motor 312 rotates, the spiral dragon 314 is driven by the belt transmission part 315 to input the polyester chips 200. During the movement of the polyester chips 200 in the feeding pipe 313, the cam 311 rotates to drive the first rack 324 to move up and down, thereby driving the first gear 323 to rotate reciprocatingly. The first gear 323 drives the swing rod 321 and the swing plate 322 to float up and down, thereby scattering the falling polyester chips 200, and then falling on the first tray 113. At the same time, the cam 311 drives the insulation box 112 and the first tray 113 to vibrate by cooperating with the first telescopic part 111, so that the polyester chips 200 are vibrated evenly on the first tray 113, and some powder is shaken off. In addition, the first tray 113 will also work at the same time as the polymerization component 21 is working, so as to reduce the pressure of the polyester chips 200 input to the drying component 22 to prevent blockage.

[0098] It should be noted that a mounting rod is connected to the feed pipe 313 , and a return spring connected to the first rack 324 is arranged on the mounting rod. The return spring is used to drive the rack 324 to move downward and return to its original position during the up and down floating process of the swing plate 322 .

[0099] Working steps

[0100] First, the large volume of polyester material is transported to the cooling pool for cooling and slitting. After the slitting of the polyester chips 200 is completed, smaller particles of raw materials are formed. These polyester chips 200 are transported to the centrifugal device together with the water flow. The raw materials and water are separated by filtration before entering the centrifugal device. Then hot air is introduced. Under the action of wind, the polyester chips 200 gradually rotate upward from the bottom of the centrifugal device, complete their own moisture drying and output from the top conduit, and then enter the processing mechanism 1 through the input mechanism 3. The hot air is output from the exhaust duct at the top of the centrifugal device and is reheated and reused;

[0101] Then the vibration component 31 drives the polyester chips 200 to be output, and drives the heat preservation box 112 and the first tray 113 to vibrate, so that the polyester chips 200 are evenly distributed on the first tray 113 by vibration. During the falling process, the polyester chips 200 are scattered by the pre-separation component 32, further accelerating the dispersion efficiency.

[0102] In the processing mechanism 1, the polyester slices 200 are firstly separated as a whole by the toggle component 11 and evenly spread to the surroundings. In the second step, the polyester slices 200 that are closely combined with each other are separated by the kneading component 12 through the mutual force. In the third step, the kneading component 12 cooperates with the vibration component 31 to vibrate, and the two are performed alternately to completely remove the powder on both sides of the polyester slices 200. At this time, due to the influence of the temperature of the drying component 22 on the first tray 113, the polyester slices 200 located on the first tray 113 also achieve a certain preheating effect; then the drying component 22 drives the first tray 113 to rotate rapidly, so that the polyester slices 200 located on the top of it move to the edge due to the centrifugal force, and then the polyester slices 200 are slowly rotated to cooperate with the polymerization component 21 to send the polyester slices 200 into the drying component 22 for drying and pre-crystallization;

[0103] During the process, the two groups of flipping components 23 enable the polyester chips 200 to complete the intermittent input drying component 22 to maintain a certain distance and flip over during the drying process. In addition, the temperature control component 24 adjusts the drying temperature in real time. Finally, the polyester chips 200 are output and collected through the three-way pipe 241.

[0104] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
