[0002] In the electronics industry, electronic carrier tape is a commonly used packaging material for automated handling and transportation of electronic components. Electronic carrier tape is usually made of polycarbonate (PC) material, which has excellent mechanical and optical properties. However, during the injection molding process, a large amount of PC waste is generated. If it is not handled, this waste will not only cause a waste of resources, but also may have adverse effects on the environment.

[0003] At present, there are still many challenges in the recycling and reuse technology and equipment of PC waste, especially in how to effectively convert PC waste into composite plastic materials with new properties.

DETAILED DESCRIPTION

[0031] In order to facilitate solving the problems described in the background technology, an embodiment of the present invention provides an electronic carrier injection molding waste treatment device. The technical scheme in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-8 This embodiment provides an electronic carrier tape injection molding waste treatment device, comprising:

[0033] The barrel 100 provides a closed environment for the fusion and mixing of the plastic material;

[0034] The barrel 100 is provided with a shell 200 outside, which wraps the barrel 100 to provide protection and further improve the airtightness; the plastic material enters the barrel 100 through the feed port 110;

[0035] The driving mechanism 300 is disposed inside the barrel 100 to mix and propel the plastic material inside the barrel 100. The work of the melting zone 720 and the mixing zone 730 inside the barrel 100 is completed by the driving mechanism 300.

[0036] The temperature control mechanism 400 is arranged outside the barrel 100 to control the temperature of the barrel 100. The heater 410 provides heating for the barrel 100. The liquid cooling plate 430 cools down the barrel 100 on the basis of heating the barrel 100 by the heater 410, thereby completing the temperature control.

[0037] The molding mechanism 500 is arranged inside the barrel 100, and punches the plastic material mixed by the driving mechanism 300. After the mixed plastic material is melted and mixed by the driving structure inside the barrel 100, it is transported to the exhaust area 740 and exhausted through the exhaust port 120, and finally reaches the punching area 750 under the action of the driving mechanism 300;

[0038] The controller 600 is disposed on the housing 200 , receives the signal sent by the temperature control mechanism 400 , and completes the regulation of the controller 600 according to the received signal; a human-machine interface 610 is disposed on the top surface of the controller 600 .

[0039] Specifically, the temperature control mechanism 400 includes a heater 410, which is arranged on the outside of the barrel 100, and uses an electric heating ring to heat the barrel 100, which is arranged around the barrel 100 to heat the raw material to the required processing temperature; a temperature sensor 420, which is arranged on the outside of the barrel 100, located in different temperature control zones of the barrel 100, and monitors the temperature of different temperature control zones of the barrel 100; an insertion groove 432, which is arranged on the shell 200, and the liquid cooling plate 430 enters the inside of the shell 200 from the insertion groove 432, so as to be close to the barrel 100; a lifting rod 431, which is arranged on both sides of the insertion groove 432, and is located on the outside of the shell 200, to help the liquid cooling plate 430 to move inside the insertion groove 432; the liquid cooling plate 430, which is arranged on the lifting rod 431, is located on a plurality of lifting rods 431, each liquid cooling plate 430 has a corresponding temperature control zone, and the liquid cooling plates 430 in different temperature control zones are independently controlled by the controller 600 to control the temperature of the corresponding temperature control zone; the solenoid valve 433 is arranged on the liquid cooling plate 430 to control the entry and outflow of the cooling liquid inside the liquid cooling plate 430; the hose 434 is arranged on the solenoid valve 433, connecting the solenoid valve 433 and the cooling chamber 435, and the cooling liquid reaches the solenoid valve 433 from the cooling chamber 435 through the hose 434; the cooling chamber 435 is arranged outside the housing 200 and connected to the hose 434, the cooling liquid is stored in the cooling chamber 435, and the cooling liquid flowing out of the liquid cooling plate 430 is dissipated in the cooling chamber 435; the support rod 436 is arranged outside the housing 200 and connected to the cooling chamber 435;

[0040] The temperature control process of the liquid cooling plate 430 is as follows: first, the working temperature of each electric heating ring is set, and the actual temperature data monitored by the temperature sensor 420 is transmitted to the controller 600. When the actual temperature of a certain temperature control zone is higher than the set temperature by more than 2°C, the controller 600 opens the liquid inlet solenoid valve 433 of the liquid cooling plate 430, and controls the lifting rod 431 of this section at the same time, so that the liquid cooling plate 430 is close to the barrel 100 wall of this temperature control zone. When the temperature drops to within the error range, the liquid cooling plate 430 is away from the barrel 100 wall to achieve dynamic temperature balance in this section. After the temperature control mechanism 400 ends, the liquid outlet solenoid valve 433 of the liquid cooling plate 430 is opened, and the coolant flows back into the cooling chamber 435.

[0041] Specifically, the driving mechanism 300 includes a twin screw 310, which is arranged inside the barrel 100; a pulley 320, which is arranged at the driving end of the twin screw 310, and the driving end of the twin screw 310 is one end of the twin screw 310 connected to the transmission shaft of the motor 340, which is located outside the barrel 100 and is arranged inside the housing 200; the motor 340 is arranged outside the housing 200, and the connecting belt 330 is arranged on the transmission shaft of the pulley 320 and the motor 340. The motor 340 transmits power to the pulley 320 through the connecting belt 330, thereby transmitting power to the twin screw 310 connected to the pulley 320, thereby realizing the rotation of the twin screw 310.

[0042] Specifically, the molding mechanism 500 includes a punching machine 520, which is arranged outside the housing 200 and provides power for the punching action of the punching head 530; a telescopic rod 510, which is arranged inside the barrel 100 and connected to the punching machine 520 to control the up and down movement of the punching head 530; the punching head 530, which is arranged inside the barrel 100 and connected to the telescopic rod 510, and performs punching and shaping on the plastic material moved into the punching groove 540; the punching groove 540 is arranged below the barrel 100; the punching die 550, which is arranged inside the punching groove 540 and punches the mixed plastic material into a desired shape; and a discharge port 560, which is arranged below the punching die 550, and the punched plastic material leaves the barrel 100 from here.

[0043] Specifically, the barrel 100 is divided into five temperature control zones, each of which can be cooled separately; the five temperature control zones are respectively a feeding zone 710, a melting zone 720, a mixing zone 730, an exhaust zone 740 and a stamping zone 750; the five temperature control zones have different functions as follows: feeding zone 710: this zone usually maintains a lower temperature to facilitate the conveying and compaction of solid materials; melting zone 720: the temperature gradually rises to melt the material while ensuring that the material is fully melted; mixing zone 730: maintain an appropriate temperature to ensure uniform mixing and reaction of the material; exhaust zone 740: appropriate temperature control helps to effectively discharge volatiles or gases; stamping zone 750: in this zone, the temperature remains stable to ensure the fluidity of the material and the dimensional accuracy of the final product. The specific temperatures are:

[0044] Temperature / ℃ Feeding area 710 Melting zone 720 Mixed Zone 730 Exhaust area 740 Stamping area 750 set up 205 210 215 220 230

[0045] It is necessary to ensure that the actual temperature is no more than 2°C higher than the set temperature.

[0046] Specifically, the positions of the insertion holes correspond to the positions of the five temperature control zones, ensuring that each temperature control zone has its own exclusive liquid cooling plate 430 to cool the temperature control zone, thereby distinguishing the temperatures of different temperature control zones.

[0047] Specifically, the two screws of the twin screw 310 are placed in parallel in the barrel 100, and the two screws rotate in opposite directions and couple with each other, so as to ensure that the twin screw 310 can push the plastic material forward during the rotation process and simultaneously complete the mixing and stirring of different types of plastic materials.

[0048] Example:

[0049] like Figure 3 , 5 As shown in , 7 and 8, the driving mechanism 300 is powered by the motor 340, the pulley 320 is arranged at the driving end of the twin screw 310, the pulley 320 is connected to the transmission shaft of the motor 340 through the connecting belt 330, and the power of the motor 340 is transmitted to the twin screw 310, and the twin screw 310 obtains power to mix the mixed plastic material.

[0050] like Figure 1 , 2 As shown in , 3, 4, and 5, the temperature control mechanism 400 heats the barrel 100 through the heater 410 to ensure that the temperature inside the barrel 100 is not too low; the temperature of the barrel 100 is monitored through the temperature sensor 420. When the temperature sensor 420 detects that the actual temperature of the abnormal temperature control zone is higher than the set temperature by more than 2°C, the abnormal temperature information is sent to the controller 600. The controller 600 sends a control command based on the received abnormal temperature information to control the liquid cooling plate 430 corresponding to the abnormal temperature control zone to start working. The solenoid valve 433 receives the control command sent by the controller 600 and controls the coolant to enter the cooling chamber 435 through the hose 434; while the coolant enters the liquid cooling plate 430, the lifting rod 431 controls the liquid cooling plate 430 to enter and exit the insertion groove 432 to control the temperature of the barrel 100. When the temperature sensor 420 in the abnormal temperature control zone detects that the temperature in the barrel 100 returns to the normal range, the temperature sensor 420 sends normal temperature information to the controller 600. After receiving the normal temperature information, the controller 600 sends a control command to the solenoid valve 433 to control the coolant to flow from the liquid cooling plate 430 back to the cooling chamber 435, ensuring that the coolant can be cooled and ensuring the cooling efficiency of the coolant.

[0051] like Figure 2 , 3As shown in , 4, 5, and 6, the molding mechanism 500 provides the punching power through the punching machine 520, and the punching power is transmitted to the punching head 530 through the telescopic rod 510; when the twin screws 310 of the driving mechanism 300 transport the mixed plastic material to the inside of the punching groove 540, the punching machine 520 drives the punching head 530 through the telescopic rod 510 to punch the mixed plastic material inside the punching groove 540, and the pressure of the punching head 530 causes the mixed plastic material to be die-casted through the stamping die 550; the mixed plastic material that has completed shaping leaves the barrel 100 through the discharge port 560.

[0052] In order to verify the properties of PET / PC composite materials and obtain the optimal mixing ratio, three groups of comparative tests were carried out in the laboratory.

[0053] Example 1: Using PTW as a compatibilizer to modify PET / PC composite materials:

[0054] Before the experiment, PET particles were dried in a vacuum drying oven at 130°C, PC particles at 120°C, and PTW at 60°C for 12 hours, 4 hours, and 2 hours, respectively, with a vacuum degree of 0.08MPa to remove the influence of moisture. Then, the blend was prepared at a specific mass percentage in a melt mixing device at 200-240°C, and the speed was set to 80r / min. After extrusion granulation and drying, the test specimens were prepared by injection molding. The specific experimental formula is shown in Table 1.

[0055] Table 1 Experimental formula for preparing PET / PC composite materials

[0056]

[0057] Example 2: Modification of PET / PC composite material using EP as chain extender

[0058] Before the experiment, PET particles were dried in a vacuum drying oven at 130°C, PC particles at 120°C, and PTW at 60°C for 12 hours, 4 hours, and 2 hours, respectively, with a vacuum degree of 0.08MPa to remove the influence of moisture. Then, the blend was prepared at a specific mass percentage in a melt mixing device at 200-240°C, and the speed was set to 80r / min. After extrusion granulation and drying, the test specimens were prepared by injection molding. The specific experimental formula is shown in Table 2.

[0059] Table 2 Experimental 2 formula for preparing PET / PC composite materials

[0060]

[0061]

[0062] Example 3: Modification of PET / PC composites with PTW and EP

[0063] Before the experiment, PET particles were dried in a vacuum drying oven at 130°C, PC particles at 120°C, and PTW at 60°C for 12 hours, 4 hours, and 2 hours, respectively, with a vacuum degree of 0.08MPa to remove the influence of moisture. Then, the blend was prepared at a specific mass percentage in a melt mixing device at 200-240°C, and the speed was set to 80r / min. After extrusion granulation and drying, the test specimens were prepared by injection molding. The specific experimental formula is shown in Table 3.

[0064] Table 3 Experimental formula for preparing PET / PC composite materials

[0065]

[0066] Experimental results: Increasing the PTW content improves the impact strength of the PET / PC composite material, but slightly reduces the tensile and flexural strength. When PTW reaches 10%, the comprehensive mechanical properties are optimal, and the impact strength is 11.74 kJ / m 2 The tensile strength is about 47MPa, which is similar to that without PTW. Increasing the EP content causes the impact strength to increase first and then decrease, with a maximum value of 5.5kJ / m 2 , but the tensile and flexural strengths are about 10MPa higher than when PTW is used alone. Combining PTW and EP, the strength of the composite material is better than that of the single use, especially when PTW is 10% and EP is 0.9%, the impact strength reaches 13.47kJ / m 2 .

[0067] Therefore, a formula of 10% PTW and 0.9% EP was selected to modify the PET / PC composite material.

[0068] After the formula obtained through the experiment is weighed and proportioned, the mixed plastic material is poured into the barrel 100 from the feed port 110, and the housing 200 provides protection for the entire equipment.

[0069] The driving mechanism 300 is started, and the driving mechanism 300 is powered by the motor 340. The pulley 320 is set at the driving end of the twin screw 310. The pulley 320 is connected to the transmission shaft of the motor 340 through the connecting belt 330 to transmit the power of the motor 340 to the twin screw 310.

[0070] Separate temperature-controlled zones process mixed plastic materials at different locations.

[0071] The temperature control zones are respectively the feeding zone 710, the melting zone 720, the mixing zone 730, the exhaust zone 740 and the stamping zone 750; the feeding zone 710 maintains a relatively low temperature to facilitate the conveying and compacting of the plastic material by the twin screw 310, and the twin screw 310 conveys the plastic material to the melting zone 720. The temperature of the melting zone 720 is gradually increased compared to the temperature of the feeding zone 710 to melt the material, while ensuring that the material is fully melted. After the plastic material is melted in the melting zone 720, it is transported to the mixing zone 730 by the twin screw 310; the mixing zone 730 maintains an appropriate temperature to ensure uniform mixing and reaction of the plastic material. After the plastic material is mixed and reacted in the mixing zone 730, it is conveyed to the exhaust zone 740 by the twin screw 310. Maintaining appropriate temperature control in the exhaust zone 740 is conducive to the effective discharge of volatiles or gases, and the discharged volatiles or gases leave the inside of the barrel 100 through the exhaust port 120. After the exhaust is completed, the mixed plastic material is conveyed to the stamping zone 750. The temperature of the plastic material in the stamping area is kept stable at 750°C to ensure the fluidity of the material and the dimensional accuracy of the final product, ensuring the normal progress of the stamping work.

[0072] The temperature control mechanism 400 heats the temperature control zone of the barrel 100 through the heater 410 to ensure that the temperature inside the barrel 100 will not be lower than 200°C. At the same time, the overall temperature will not be higher than 240°C and is within the required range; the temperature of the barrel 100 is monitored by the temperature sensor 420. When the temperature sensor 420 detects that the temperature of the temperature control zone is abnormal and the actual temperature exceeds the set temperature by 2°C, the temperature sensor 420 detects and sends abnormal temperature information to the controller 600. The controller 600 sends a control command to the liquid cooling plate 430 based on the received abnormal temperature information, and controls the liquid cooling plate 430 corresponding to the abnormal temperature control zone to start working. The solenoid valve 433 at the water inlet of the liquid cooling plate 430 receives the control command from the controller 600, and controls the coolant to enter the cooling chamber 435 through the hose 434; while the coolant enters the liquid cooling plate 430, the lifting rod 431 controls the liquid cooling plate 430 to enter and exit the insertion groove 432, and controls the contact and separation between the liquid cooling plate 430 and the barrel 100, so as to control the temperature of the barrel 100. When the temperature sensor 420 in the abnormal temperature control zone detects that the temperature in the barrel 100 returns to the normal range, the temperature sensor 420 sends the normal temperature information to the controller 600. After receiving the normal temperature information, the controller 600 sends a control command to the liquid outlet solenoid valve 433, and controls the coolant to flow back from the liquid cooling plate 430 to the cooling chamber 435, so as to ensure that the coolant can be cooled and the cooling efficiency of the coolant is guaranteed. The support rod 436 provides fixing and support for the cooling chamber 435.

[0073] When the twin screws 310 of the driving mechanism 300 transport the completed mixed plastic material to the inside of the punching groove 540, the punching machine 520 drives the punching head 530 through the telescopic rod 510 to punch the mixed plastic material inside the punching groove 540. The pressure of the punching head 530 causes the mixed plastic material to be die-casted through the stamping die 550, and the mixed plastic material that has been shaped leaves the barrel 100 through the discharge port 560.

[0074] The staff can monitor the temperature of each temperature control zone of the barrel 100 in real time through the human-machine interface 610 on the controller 600, and can also adjust the heating temperature of the heater 410 and the set temperature according to different processing materials to adjust the mixing of different materials.

[0075] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
