Description

Technical Field

[0001] This utility model relates to the field of color masterbatch production technology, specifically a screw-type color masterbatch precision weighing device. Background Technology

[0002] Color masterbatch, also known as colorant or pigment preparation, is a new type of colorant specifically designed for coloring polymer materials. It is mainly composed of three basic elements: pigment or dye, carrier, and additives. By uniformly loading an extraordinary amount of pigment into the resin, a pigment concentrate is formed, which has a higher coloring power than the pigment itself. As an indispensable additive in the production of plastic products, the accuracy of the amount of color masterbatch added has a key impact on the final quality of plastic products.

[0003] However, current precision weighing devices for color masterbatches typically only have one weighing station. After one set of color masterbatches is weighed, personnel often need to unload the material before the next set of color masterbatches can be weighed, thus extending the time required for weighing operations and affecting production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a screw-type masterbatch precision weighing device with dual weighing stations, which can quickly switch between the two weighing stations during weighing operations, thus improving the efficiency of weighing operations.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a screw-type masterbatch precision weighing device, comprising a support platform, a screw feeder fixedly installed at the right end of the top of the support platform, a PLC controller fixedly installed at the right end of the screw feeder, a servo motor fixedly installed at the left end of the bottom of the support platform, a support plate fixedly installed at the output end of the servo motor, weighing sensors fixedly installed at both ends of the top of the support plate, a support frame fixedly installed on the top of the weighing sensors, and a weighing cylinder fixedly connected to the top of the support frame.

[0006] As a preferred embodiment, a magnetic block is fixedly connected to the left end of the top of the support platform and in front of the servo motor; magnetic control switches are fixedly installed at both ends of the bottom of the support plate; a solenoid valve is fixedly installed at the bottom of the weighing cylinder; a discharge pipe is fixedly installed at the bottom of the solenoid valve; a receiving hopper is fixedly connected to the left end of the support platform and in front of the magnetic block; and a discharge pipe is fixedly connected to the bottom of the receiving hopper.

[0007] As a preferred embodiment, a mounting bracket is fixedly connected to the middle of the top of the support platform, and the top of the mounting bracket is fixedly installed at the middle of the screw feeder.

[0008] As a preferred embodiment, an annular frame is fixedly connected between the two sides of the support plate, and a first ball bearing is movably connected between the bottom of the annular frame and the left end of the top of the support platform.

[0009] As a preferred embodiment, both ends of the top of the support plate are fixedly connected to a fixing frame, the upper end of the fixing frame is fixedly connected to a guide frame, and a second ball bearing is movably connected between the inner cavity of the guide frame and the outer surface of the weighing cylinder.

[0010] As a preferred embodiment, the number of fixing brackets is six, and the shape of the fixing brackets is L-shaped.

[0011] As a preferred embodiment, a support column is fixedly connected to the bottom of the support platform, and a load-bearing base plate is fixedly connected to the bottom of the support column.

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

[0013] 1. This utility model, through the configuration of a PLC controller, screw feeder, weighing cylinder, weighing sensor, servo motor, support plate, and support frame, enables precise weighing of masterbatch while allowing switching between two weighing stations. This effectively reduces the time interval required for multiple weighing operations of masterbatch and significantly improves the efficiency of the weighing process.

[0014] 2. This utility model, through the arrangement of magnetic blocks, magnetic control switches, solenoid valves, feeding pipes, receiving hoppers, and discharge pipes, ensures that during the weighing and position switching process of the two sets of weighing cylinders on the masterbatch, the weighing cylinder after weighing is positioned above the receiving hopper, while the corresponding magnetic control switch is positioned above the magnetic block. Under the magnetic force of the magnetic block, the contacts inside the magnetic control switch close, and the circuit of the solenoid valve below the weighing cylinder after weighing is connected and opened. This allows the masterbatch inside the weighing cylinder to fall into the receiving hopper through the feeding pipe and be discharged along the discharge pipe, thus achieving the effect of automatic discharge of the masterbatch after weighing.

[0015] 3. This utility model achieves the purpose of supporting the screw feeder through the setting of the mounting frame, and achieves the purpose of supporting the support plate through the setting of the annular frame and the first ball bearing, thus preventing the support plate from tilting due to force. Through the setting of the fixing frame, the guide frame and the second ball bearing, the weighing cylinder can be guided to perform symmetrical operation, thus preventing the weighing cylinder from tilting due to force. Through the setting of the support column and the weighing base plate, the bottom of the support platform is supported. Attached Figure Description

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0023] Example 1:

[0024] Please see Figures 1-4 As shown, this utility model provides a screw-type masterbatch precision weighing device, including a support platform 5. A screw feeder 1 is fixedly installed at the right end of the top of the support platform 5. A PLC controller 16 is fixedly installed at the right end of the screw feeder 1. A servo motor 9 is fixedly installed at the left end of the bottom of the support platform 5. A support plate 7 is fixedly installed at the output end of the servo motor 9. Weighing sensors 11 are fixedly installed at both ends of the top of the support plate 7. A support frame 10 is fixedly installed on the top of the weighing sensors 11. A weighing cylinder 3 is fixedly connected to the top of the support frame 10.

[0025] In this technical solution, by setting up a PLC controller 16, a screw feeder 1, a weighing cylinder 3, a weighing sensor 11, a servo motor 9, a support plate 7, and a support frame 10, the precise weighing of masterbatch is achieved. At the same time, the switching between the two weighing stations effectively reduces the time required for multiple weighing operations of masterbatch, thus improving the efficiency of the weighing operation.

[0026] Example 2:

[0027] Based on Embodiment 1, this utility model is as follows: Figure 2 and Figure 3 As shown, a magnetic block 13 is fixedly connected to the left end of the top of the support platform 5 and in front of the servo motor 9. Magnetic control switches 12 are fixedly installed at both ends of the bottom of the support plate 7. A solenoid valve 20 is fixedly installed at the bottom of the weighing cylinder 3. A discharge pipe 14 is fixedly installed at the bottom of the solenoid valve 20. A receiving hopper 8 is fixedly connected to the left end of the support platform 5 and in front of the magnetic block 13. A discharge pipe is fixedly connected to the bottom of the receiving hopper 8.

[0028] In this technical solution, by setting up magnetic block 13, magnetic control switch 12, solenoid valve 20, feeding pipe 14, receiving hopper 8 and discharge pipe, during the process of weighing the masterbatch and switching positions of the two sets of weighing cylinders 3, the weighing cylinder 3 after weighing can be positioned above the receiving hopper 8, and the magnetic control switch 12 at the corresponding position can be positioned above the magnetic block 13. Under the action of the magnetic force of the magnetic block 13, the contacts inside the magnetic control switch 12 are closed, and the circuit of the solenoid valve 20 below the weighing cylinder 3 after weighing is connected and opened. Thus, the masterbatch inside the weighing cylinder 3 can fall into the receiving hopper 8 through the feeding pipe 14 and be discharged along the discharge pipe, thereby achieving the effect of automatic discharge of the masterbatch after weighing.

[0029] Example 3:

[0030] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, a mounting bracket 2 is fixedly connected to the middle of the top of the support platform 5. The top of the mounting bracket 2 is fixedly installed at the middle of the screw feeder 1. An annular frame 4 is fixedly connected between the two sides of the support plate 7. A first ball bearing 15 is movably connected between the bottom of the annular frame 4 and the left end of the top of the support platform 5. Fixing brackets 19 are fixedly connected to both ends of the top of the support plate 7. A guide frame 17 is fixedly connected to the upper end of the fixing bracket 19. A second ball bearing 18 is movably connected between the inner cavity of the guide frame 17 and the outer surface of the weighing cylinder 3. There are six fixing brackets 19. The fixing brackets 19 are L-shaped. A support column 6 is fixedly connected to the bottom of the support platform 5. A load-bearing base plate is fixedly connected to the bottom of the support column 6.

[0031] In this technical solution, the mounting frame 2 is used to support the screw feeder 1. The annular frame 4 and the first ball bearing 15 are used to support the support plate 7, preventing the support plate 7 from tilting due to force. The fixed frame 19, the guide frame 17, and the second ball bearing 18 are used to guide the weighing cylinder 3, preventing the weighing cylinder 3 from tilting due to force. The support column 6 and the weighing base plate are used to support the bottom of the support platform 5.

[0032] The working principle of this utility model is as follows: By adding the color masterbatch to be processed into the hopper of the screw feeder 1, and starting the screw feeder 1 through the PLC controller 16, the color masterbatch can be gradually conveyed into the weighing cylinder 3 located on the left. At the same time, through the setting of the weighing sensor 11, the color masterbatch conveyed in the weighing cylinder 3 can be weighed. When the weight of the color masterbatch in the weighing cylinder 3 is within the parameter range set by the PLC controller 16, the PLC controller 16 can control the screw feeder 1 to stop working and simultaneously start the servo motor 9 to work 180 degrees (it should be noted that the rotation angle of the servo motor 9 is 180 degrees each time the PLC controller 16 starts working, and the rotation direction of the servo motor 9 is opposite when working two consecutive times). The servo motor 9 drives the support plate 7, the weighing sensor 11, the support frame 10 and the weighing cylinder 3 to rotate 180 degrees, so that the positions of the two sets of weighing cylinders 3 can be switched, so as to weigh the color masterbatch again.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
