Description

Technical Field

[0001] The utility model relates to the technical field of plastic masterbatch processing, in particular to a plastic masterbatch proportioning feeding device. Background Art

[0002] Plastic masterbatch is composed of excessive chemical additives, carrier resins and dispersants. Masterbatch is an aggregate obtained by uniformly loading an excessive amount of pigments (dyes) in resin. Masterbatch refers to the granular material obtained by mixing and kneading various additives, fillers and a small amount of carrier resin in the process of plastic processing and molding for the convenience of operation, and then through the process of metering, mixing, melting, extruding, pelletizing and other processing of equipment such as extruders.

[0003] In the production of plastic packaging, the plastic masterbatch before melting needs to be melted into a fluid state first. The port can be opened or closed by moving the movable block by the hydraulic cylinder on the shielding plate to control the amount of material entering the processing cylinder, thereby improving the versatility of the feeding device.

By arranging a servo motor, the servo motor can use the rotating rotating shaft to drive the screw to rotate inside the card interface when starting. By arranging a connecting block, the connecting block will drive the shielding plate to move up and down synchronously at the top of the processing cylinder when it moves up and down inside the card interface, so that the shielding plate can be driven away from the top surface of the processing cylinder, so that the opening on the top surface of the processing cylinder can be exposed, which is convenient for adding a large number of plastic masterbatches.

The proportioning rate is low, which affects the proportioning processing of the plastic masterbatch. Therefore, the present application provides a plastic masterbatch proportioning feeding device to meet the needs. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example: Reference Figure 1-5 The plastic masterbatch proportioning feeding device shown in the figure comprises a feeding pipe 2 which is installed through an upper shielding plate 1, weighing columns 3 are fixedly installed around the feeding pipe 2 on the shielding plate 1, a same shaking box 4 is installed between the multiple weighing columns 3, two feeding hoppers 5 are rotatably installed at the bottom of the shaking box 4, a shielding cover 6 is installed through the front side of the shaking box 4, three elastic support plates 7 are rotatably installed on both sides of the interior of the shaking box 4, a sieving net 8 is rotatably installed between the two groups of elastic support plates 7 on the shaking box 4, and the shaking box 4 is provided with a plurality of weighing columns 3. A limit valve 9 is arranged through the lower side, and an inlet pipe 10 is connected to the lower end of the shock box 4, and the inlet pipe 10 is sleeved with the feed pipe 2. The baffle plate 1 and the feed pipe 2 in this embodiment are both existing structures of the plastic masterbatch proportioning feeding device. The baffle plate 1 is located at the top of the processing cylinder of the device. The feed pipe 2 on the baffle plate 1 is connected with the processing cylinder to realize the material transportation in the middle of the feed pipe 2. The weighing column 3 is arranged between the shock box 4 and the feed pipe 2, so that the weight of the input material can be detected in real time and the material can be quantified.

[0026] A weighing sensor 13 is arranged at the bottom of the weighing column 3, and a rubber sleeve is arranged in the middle of the weighing column 3. A spring 12 is arranged in the middle of the rubber sleeve, and the bottom of the spring 12 is fixedly connected to the weighing sensor 13. The arrangement of the rubber sleeve and the spring 12 in the middle of the weighing column 3 facilitates the elastic support of the shock box 4 by the weighing column 3. The weight detection technology of the sensor is then applied to enable the weighing sensor 13 to detect the total weight of the shock box 4, thereby increasing the weight detection structure of the shock box 4 for the input material, and can perform real-time detection of the material in the shock box 4.

[0027] A weight controller 11 is fixedly connected to the front side of the shock box 4, a weighing sensor 13 is connected to the weight controller 11, and the outside of the weight controller 11 is connected to a power source.

[0028] The weight controller 11 is provided with a control button, a weight indicator light 14 and a weighing display screen 15. The weight indicator light 14 includes a preset display screen. The weight controller 11 is used to increase the detection weight display structure and the feed weight preset structure on the feeding device. The weighing display screen 15 can display the weight data detected by the weighing sensor 13 in real time.

[0029] The total width of the two shielding covers 6 is greater than the total width of the feed hopper 5 and the shock box 4. The shielding covers 6 are located on the upper side of the feed hopper 5. The setting of the two shielding covers 6 facilitates the multi-port input of materials in the shock box 4, reduces the dust phenomenon of the input materials, and by closing the feed hopper 5 with the shielding covers 6, the shock box 4 can be used in a sealed manner, thereby increasing the feeding cleanliness of the feeding device.

The same support plate spring 16 is fixedly connected between the elastic support plates 7 and the shock box 4. The screening net 8 is fixedly connected to the shock box 4 through the support plate spring 16. The use of the elastic support plates 7 facilitates the increase of the elastic supporting structure at the bottom of the screening net 8. The rotational connection between the elastic support plates 7 and the shock box 4 and the use of the support plate spring 16 between the elastic support plates 7 and the shock box 4 facilitate the elastic support plates 7 on both sides to vibrate the screening net 8, thereby achieving the shock dispersion of the material and improving the uniformity of the material.

Through the use of the limiting plate 17, it is convenient to increase the limiting structure on the upper side of the screening net 8, limit the rotation angle of the screening net 8, and realize the shock dispersion of the material on the upper side of the screening net 8.

[0032] How this utility works:

[0033] When in use, according to the ratio requirement of plastic masterbatch, use the control button on the weight controller 11, preset the feed weight on the weight indicator light 14 set in the weight controller 11, and then open the shielding cover 6 on the top of the shock box 4, and pour the material into the shock box 4 through the through connection between the feed hopper 5 and the shock box 4. The material presses down on the screening net 8, and the support plate spring 16 between the elastic support plate 7 and the shock box 4 is set, so that the screening net 8 can rotate at an angle between the limit plate 17 and multiple elastic support plates 7, so that the screening net 8 can shock and scatter the material on the upper side, and then pass through the screening net 8 and fall onto the limit valve 9, so as to realize the screening process of the material and improve the uniformity of the input material. In addition, through the input of the material inside the shock box 4, the shock box 4 The spring 12 in the middle of the weighing column 3 will squeeze the weighing sensor 13, and then the weight detection technology of the existing sensor will be applied. The weighing sensor 13 will transmit the detected data to the weight controller 11, and the data will be displayed through the weighing display screen 15 in the weight controller 11. When the data in the weighing display screen 15 is the same as the preset display screen on the weight indicator light 14, the weight indicator light 14 will be triggered to light up, which will facilitate the stopping of the feeding of the device. After that, by opening the limit valve 9, the loaded material can fall into the inlet pipe 10, and then pass through the feed pipe 2 into the processing cylinder, so as to realize the precise feeding of the proportioning feeding device, increase the feeding weighing structure of the proportioning feeding device, and thus improve the use effect of the proportioning feeding device, which is practical.
