Description

Technical Field

[0001] This application relates to the field of plastic masterbatch technology, specifically a plastic masterbatch proportioning and feeding device. Background Technology

[0002] Plastic masterbatch is composed of excessive amounts of chemical additives, carrier resins, and dispersants. Masterbatch is an aggregate obtained by uniformly loading excessive amounts of pigments (dyes) into resin. Plastic masterbatch proportioning and feeding device is an automated equipment used in the plastics processing industry. Its core function is to accurately control the proportion of different types of plastic masterbatch and uniformly transport them to the next process.

[0003] Currently, plastic masterbatch proportioning and feeding devices generally use screw conveyors to a chamber to mix different types of plastic masterbatches, and then transport the proportioned plastic masterbatch to the next process. However, the weighing relies on static weighing, which is inconvenient for real-time adjustment during the feeding process. If too much material is added, it needs to be manually removed, which increases the difficulty of the workers' work and increases the proportioning error. Utility Model Content

[0004] The purpose of this application is to provide a plastic masterbatch proportioning and feeding device, which solves the problems of the plastic masterbatch proportioning and feeding devices proposed in the background art, which generally use a screw to transport materials to a chamber, then mix different types of plastic masterbatches, and then transport the proportioned plastic masterbatch to the next process. However, the weighing relies on static weighing, which is inconvenient to adjust in real time during the feeding process. If the material is over-added, it needs to be manually removed, which increases the difficulty of the workers' work and increases the proportioning error.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This application provides a plastic masterbatch proportioning and feeding device, including a mixing cylinder. A top cover is fixedly installed on the upper end of the mixing cylinder. Two feeding pipes are welded to the upper end of the top cover. Weighing pipes are fixedly installed on the upper ends of the two feeding pipes respectively. Output pipes are fixedly installed on the upper ends of the two weighing pipes respectively. A hopper is welded to the upper ends of the two output pipes respectively. A set of first solenoid valves is fixedly installed on the outer walls of the two output pipes respectively. A reciprocating motor is fixedly installed on the outer walls of the two weighing pipes respectively. A weighing device is fixedly installed on the output shaft of the reciprocating motor located inside each weighing pipe. The outer shell of the weighing device is slidably disposed from the inner wall of the weighing pipe. An outer tube is fixedly installed on the outer wall of the weighing pipe above each weighing device at an angle. An electric push rod is fixedly installed on the end of each outer tube away from the weighing pipe respectively. A plug is fixedly installed on the telescopic end of each electric push rod respectively. Each plug is slidably connected to the inner wall of the corresponding outer tube.

[0006] By adopting the above technical solution, a weighing device driven by a reciprocating motor is installed inside the weighing tube. Combined with an outer tube, an electric push rod, and a plug structure, dynamic weighing and real-time adjustment functions are achieved. When the weighing device detects that the weight of the masterbatch exceeds the preset value, the electric push rod pulls the plug to move outward. The masterbatch inside the weighing tube enters the outer tube under its own weight, reducing the amount of masterbatch inside the weighing tube until it reaches the required load capacity of the weighing device. The reciprocating motor drives the weighing device to rotate, discharging the masterbatch above the weighing device. Furthermore, the masterbatch in the outer tube can be pushed into the weighing tube when the next batch of masterbatch is fed, reducing the difficulty of manual intervention and minimizing proportioning errors.

[0007] Optionally, the outer walls of the two hoppers are fixedly mounted with the same bracket, and the lower end of the bracket is fixedly mounted with the upper end of the top cover.

[0008] By adopting the above technical solution, the top cover can fix the bracket, and the bracket can fix and support the two hoppers.

[0009] Optionally, the lower end of the mixing cylinder is welded with multiple sets of support legs.

[0010] By adopting the above technical solution, the mixing cylinder can fix the support legs, and the support legs can be connected to the outer wall of the feed end of the next processing step of the plastic masterbatch.

[0011] Optionally, a discharge pipe is welded to the lower end of the mixing cylinder, and a second solenoid valve is fixedly installed on the outer wall of the discharge pipe.

[0012] By adopting the above technical solution, the mixing cylinder can fix the discharge pipe, while the second solenoid valve can open and close the discharge pipe, thereby facilitating the feeding of the mixed plastic masterbatch.

[0013] Optionally, a convex cover is fixedly installed on the upper end of each of the two hoppers, a flip cover is hinged to the upper end of each convex cover, a first drive motor is fixedly installed on the upper end of each convex cover, a second stirring rod is fixedly installed on the output shaft of each first drive motor, and the two second stirring rods are located inside the corresponding hoppers.

[0014] By adopting the above technical solution, the hopper can fix the convex cover, and the convex cover can provide rotational support for the flip cover, thereby facilitating the opening and closing of the hopper. The first drive motor can drive the second stirring rod to rotate and stir and feed the plastic masterbatch inside the corresponding hopper.

[0015] Optionally, a second drive motor is fixedly installed on the upper end of the top cover, and a first stirring rod is fixedly installed on the output shaft of the second drive motor. The first stirring rod is located inside the mixing cylinder.

[0016] By adopting the above technical solution, the top cover can fix the second drive motor, and the second motor can rotate the first stirring rod to mix and stir the different plastic masterbatches inside the mixing drum.

[0017] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows: The technical solution of this application achieves dynamic weighing and real-time adjustment functions by setting a weighing device driven by a reciprocating motor inside the weighing tube, in conjunction with an outer tube, an electric push rod, and a plug structure. When the weighing device detects that the weight of the masterbatch exceeds the preset value, the electric push rod pulls the plug to move outward. The masterbatch inside the weighing tube enters the outer tube under its own weight, reducing the amount of masterbatch inside the weighing tube until it reaches the load-bearing capacity required by the weighing device. The reciprocating motor drives the weighing device to rotate, discharging the masterbatch above the weighing device. Furthermore, the masterbatch in the outer tube can be pushed into the weighing tube when the next batch of masterbatch is fed, reducing the difficulty of manual intervention and reducing the proportioning error.

[0020] 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.

[0021] Please see Figure 1-5 This application provides a technical solution: a plastic masterbatch proportioning and feeding device, including a mixing cylinder 1, a top cover 15 fixedly installed on the upper end of the mixing cylinder 1, two feeding pipes 2 welded to the upper end of the top cover 15, weighing pipes 3 fixedly installed on the upper ends of the two feeding pipes 2 respectively, output pipes 4 fixedly installed on the upper ends of the two weighing pipes 3 respectively, hoppers 5 welded to the upper ends of the two output pipes 4 respectively, a set of first solenoid valves 6 fixedly installed on the outer walls of the two output pipes 4 respectively, and the outer walls of the two weighing pipes 3 respectively fixed with... A reciprocating motor 8 is installed, and a weighing device 7 is fixedly installed on the output shaft of the reciprocating motor 8 located inside each weighing tube 3. The outer shell of the weighing device 7 is slidably set with the inner wall of the weighing tube 3. An outer tube 9 is fixedly installed on the outer wall of the weighing tube 3 above each weighing device 7 at an incline. An electric push rod 10 is fixedly installed at the end of each outer tube 9 away from the weighing tube 3. A plug 11 is fixedly installed on the telescopic end of each electric push rod 10. Each plug 11 is slidably connected to the inner wall of the corresponding outer tube 9. In the technical solution of this application, a weighing device 7 driven by a reciprocating motor 8 is installed inside the weighing tube 3. Combined with the structure of the outer tube 9, electric push rod 10, and plug 11, dynamic weighing and real-time adjustment functions are achieved. When the weighing device 7 detects that the weight of the masterbatch exceeds a preset value, the electric push rod 10 pulls the plug 11 to move outward. A corresponding controller can be installed above the mixing cylinder 1. The controller is electrically connected to its electric push rod 10 and the weighing device 7 for convenient signal transmission. The masterbatch inside the weighing tube 3 enters the outer tube 9 under its own weight, thus reducing the amount of masterbatch inside the weighing tube 3. When the weighing device 7 reaches the required load capacity, the reciprocating motor 8 drives the weighing device 7 to rotate, and feeds the masterbatch above the weighing device 7. The masterbatch in the outer tube 9 can be pushed into the weighing tube 3 when the next batch of masterbatch is fed, which reduces the difficulty of manual intervention, reduces the ratio error, and reduces the error that occurs in traditional quantitative feeding, such as manual feeding, excessive feeding, or mechanical feeding, excessive feeding. Mechanical feeding generally conveys the material to the load-bearing equipment, but when mechanical feeding, such as conveyor belt feeding, pneumatic conveying feeding, or feeding hopper feeding to the weighing equipment, excessive feeding still requires manual removal.

[0022] In the technical solution of this application, such as Figure 1 , Figure 2 and Figure 4As shown, convex covers 12 are fixedly installed on the upper ends of the two hoppers 5 respectively. A flip cover 13 is hinged to the upper end of each convex cover 12. A first drive motor 14 is fixedly installed on the upper end of each convex cover 12. A second stirring rod 21 is fixedly installed on the output shaft of each first drive motor 14. The two second stirring rods 21 are located inside the corresponding hoppers 5. The hoppers 5 can fix the convex covers 12, and the convex covers can provide rotational support for the flip covers 13, thereby facilitating the opening and closing of the hoppers 5 by the flip covers 13. The first drive motor 14 can drive the second stirring rods 21 to rotate and stir and feed the plastic masterbatch inside the corresponding hoppers 5.

[0023] In the technical solution of this application, such as Figure 1 , Figure 2 and Figure 5 As shown, a second drive motor 16 is fixedly installed on the upper end of the top cover 15. A first stirring rod 17 is fixedly installed on the output shaft of the second drive motor 16. The first stirring rod 17 is located inside the mixing cylinder 1. The top cover 15 can fix the second drive motor 16, and the second motor can rotate the first stirring rod 17 to mix and stir the different plastic masterbatches inside the mixing cylinder 1.

[0024] In the technical solution of this application, such as Figure 1 , Figure 2 and Figure 5 As shown, a discharge pipe 18 is welded to the lower end of the mixing cylinder 1. A second solenoid valve 19 is fixedly installed on the outer wall of the discharge pipe 18. The mixing cylinder 1 can fix the discharge pipe 18, while the second solenoid valve 19 can open and close the discharge pipe 18, thereby facilitating the feeding of the mixed plastic masterbatch.

[0025] In the technical solution of this application, such as Figure 1 and Figure 2 As shown, the same bracket 22 is fixedly installed on the outer wall of the two hoppers 5. The lower end of the bracket 22 is fixedly installed on the upper end of the top cover 15. The top cover 15 can fix the bracket 22, and the bracket 22 can fix and support the two hoppers 5. Multiple sets of support legs 20 are welded to the lower end of the mixing cylinder 1. The mixing cylinder 1 can fix the support legs 20, and the support legs 20 can be connected to the outer wall of the feed end of the next processing step of the plastic masterbatch.

[0026] In operation, workers load different types of plastic masterbatch into two hoppers 5. The first drive motor 14 drives the second stirring rod 21 to rotate, agitating the masterbatch in the hoppers 5 to prevent blockage. Simultaneously, the first solenoid valve 6 on the output pipe 4 is opened, allowing the masterbatch to enter the weighing pipe 3 through the output pipe 4. When the weighing device 7 detects that the weight of the entering masterbatch reaches the preset value but does not exceed it, the reciprocating motor 8 drives the weighing device 7 to rotate, causing the masterbatch above the weighing device 7 to fall into the feed pipe 2 and finally enter the mixing drum 1. If the weight of the masterbatch exceeds the preset value, the electric push rod 10 pulls the plug 11 outward, removing the excess masterbatch. The granules enter the outer tube 9 under their own weight, while the weighing device 7 weighs the plastic masterbatch inside the weighing tube 3 in real time. When the plastic masterbatch ratio meets the standard, the reciprocating motor 8 drives the weighing device 7 to rotate and complete the feeding. The excess masterbatch in the outer tube 9 will be pushed back into the weighing tube 3 by the plug 11 to participate in the ratio again in the next batch of feeding. After all the masterbatch enters the mixing drum 1, the second drive motor 16 drives the first stirring rod 17 to rotate and fully mix the different types of masterbatch in the mixing drum 1. After the mixing is completed, the second solenoid valve 19 on the discharge pipe 18 is opened to transport the uniformly proportioned plastic masterbatch to the next processing step.
