Technical Field

[0001] The invention relates to the technical field of tooling equipment for production, in particular to a master batch raw material mixing storage device. Background Art

[0002] Functional masterbatch raw materials are mainly used in the manufacturing process of plastic products as additives to change the performance and application characteristics of plastic products. Functional masterbatch combines coloring and specific functions in one, which can significantly improve the physical, chemical and mechanical properties of plastic products, thereby expanding its application range and improving product quality. In the production process of plastic products, its raw materials need to be precisely mixed.

[0003] The common functional masterbatch raw material precision mixing device has a relatively simple structure, and the impurities and dust in the raw materials must be screened out during the mixing process, otherwise the impurities and dust mixed in the raw materials will have a serious impact on the production quality of plastic products; and the existing device has poor mixing effect on multiple mixing processes during the mixing process, which affects the subsequent fusion step and is not practical enough. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a master batch raw material mixing and storage device, which can simultaneously solve the problem of removing impurities during the mixing process and the problem of storage after mixing.

[0006] Furthermore, as a preferred solution of the present invention, the driving assembly includes a motor, the output end of the motor is fixedly connected to a material shifting rack located inside the material storage barrel, and a plurality of scrapers are welded around the outer periphery of the material shifting rack near the bottom end; the scrapers rotate with the rotation of the material shifting rack; when the end face of the scraper rotates to the port at the bottom of the channel and completely blocks the end face of the port at the bottom of the channel, the scraper seals the port at the bottom of the channel.

[0007] The technical effect of adopting the above-mentioned further scheme is: the rotation of the motor can drive the material rack to rotate, and then stir the raw materials put into the storage barrel. The scraper can push the raw materials that fall on the bottom of the storage barrel to the channel entrance, and can also push the raw materials to the discharge port after stirring is completed, which facilitates the discharge work and improves the convenience of use.

[0008] Furthermore, as a preferred solution of the present invention, a metal mesh is installed inside the air intake pipe near one end of the storage barrel, and the air intake pipe is connected to the channel.

[0009] The technical effect of adopting the above-mentioned further scheme is: the metal mesh can prevent the raw materials from entering the interior of the air intake pipe, and high-pressure gas can be input into the channel through the air intake pipe, thereby generating suction at the end of the channel close to the bottom, sucking the raw materials at the bottom of the storage barrel into the channel and spraying them out from the top of the channel, preventing the raw materials from sinking to the bottom and improving the mixing effect.

[0010] Furthermore, as a preferred solution of the present invention, a plurality of support columns are welded to the bottom of the shell, and the support columns are fixedly connected to the storage barrel.

[0011] Furthermore, the technical effect of adopting the above further solution is: through the fixed connection between the support column and the storage barrel, the shell can be made more firm and the stability of use can be improved.

[0012] Furthermore, as a preferred solution of the present invention, the filter is installed in a manner inclined toward the front and is fixed inside the shell by bolts.

[0013] The technical effect of adopting the above further solution is: by tilting the filter screen, the raw material can roll on the filter screen during its falling process, so that the impurities and dust are separated from the raw material, thereby improving the screening effect of the impurities and dust.

[0014] Furthermore, as a preferred solution of the present invention, a plurality of exhaust ducts are installed at equal distances from left to right on the back side of the shell near the top.

[0015] The technical effect of adopting the above further solution is: impurities and dust can be sucked out through the exhaust duct, thereby improving the filtering effect of the filter on impurities and dust, and improving production quality.

[0016] Furthermore, as a preferred solution of the present invention, a hose is installed at the bottom of the shell and at the bottom of the weighing hopper, and both ends of the hose are respectively connected to the shell and the storage barrel.

[0017] The technical effect of adopting the above further solution is that the accurately weighed raw materials can be transported to the inside of the storage barrel through the hose, thereby improving the convenience of use.

[0018] Furthermore, as a preferred solution of the present invention, electric valves are installed inside the discharge port, the feed hopper and the weighing hopper.

[0019] The technical effect of adopting the above further solution is that the closing of the discharge port, the feed hopper and the weighing hopper can be controlled at any time by the electric valve, thereby improving the convenience of use.

[0020] The beneficial effect of the present invention is that it solves the defects existing in the background technology. Through the design of the storage mechanism and the mixing mechanism, and through the design of the filter screen in conjunction with the exhaust duct, the impurities and dust contained in the raw materials can be screened quickly and efficiently, reducing the impact of the impurities and dust on the production quality and improving practicality. Through the use of the air inlet duct in conjunction with the channel, the raw materials that have settled to the bottom can be re-transported to the top of the material switching rack for repeated stirring, which greatly reduces the impact on the subsequent fusion step, effectively improves the mixing effect, and can store materials at the same time, facilitating the implementation of subsequent processes.

DETAILED DESCRIPTION

[0022] The present invention will now be described in further detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0023] like Figure 1-4A masterbatch raw material mixing storage device shown in the figure includes a storage mechanism 1, a mixing mechanism 2 is installed on the top of the storage mechanism 1, the storage mechanism 1 includes a storage barrel 101, a driving assembly 102 is installed inside the storage barrel 101 near the top, a channel 103 is opened inside the storage barrel 101 near the left side, an air intake pipe 104 is installed on the left side of the storage barrel 101 near the bottom, and a discharge port 105 is opened at the bottom of the storage barrel 101. The mixing mechanism 2 includes a shell 201, and a plurality of feed hoppers 202 are equidistantly arranged at the top of the shell 201, a filter screen 203 is installed inside the shell 201 near the top, strain gauge sensors 204 are symmetrically installed on the inner bottom of the shell 201 near the front and back sides, and weighing hoppers 205 are installed on the tops of the two strain gauge sensors 204.

[0024] like Figure 1-4As shown, the driving component 102 includes a motor 1021, and a material feeding rack 1022 is fixedly connected to the output end of the motor 1021 and is located inside the material storage barrel 101. A plurality of scrapers 1023 are welded around the outer periphery of the material feeding rack 1022 near the bottom end. The rotation of the motor 1021 can drive the material feeding rack 1022 to rotate, thereby stirring the raw materials put into the material storage barrel 101, and the scrapers 1023 can push the raw materials falling on the bottom of the material storage barrel 101 to the entrance of the channel 103, and the scrapers 1023 rotate with the rotation of the material feeding rack 1022; when the end face of the scraper 1023 rotates to the port at the bottom of the channel 103 during the rotation process and completely blocks the end face of the port at the bottom of the channel 103, the scraper 1023 can achieve the port blocking at the bottom of the channel 103, so that the raw materials can better flow to the upper outlet of the channel 103 to complete the spraying effect. At the same time, the bottom of the scraper 1023 is close to the bottom of the barrel, and the raw materials can also be pushed to the discharge port 105 after the mixing is completed, which is convenient for discharge work and improves the convenience of use. A metal mesh 1041 is installed inside the air inlet pipe 104 near one end of the storage barrel 101, and the air inlet pipe 104 is connected to the channel 103. The metal mesh 1041 can prevent the raw materials from entering the air inlet pipe 104. High-pressure gas can be input into the channel 103 through the air inlet pipe 104, so that suction is generated at the end of the channel 103 near the bottom, and the raw materials at the bottom of the storage barrel 101 are sucked into the channel 103 and sprayed out from the top of the channel 103 to prevent the raw materials from sinking to the bottom and improve the mixing effect. A plurality of support columns 2011 are welded to the bottom of the shell 201, and the support columns 2011 are fixedly connected to the storage barrel 101. The fixed connection between the support columns 2011 and the storage barrel 101 can make the shell 201 more firm and improve the stability of use. The filter screen 203 is installed in a way that is inclined to the front. Bolts are fixed inside the shell 201. Through the inclined installation of the filter 203, the raw materials can roll above it during the falling process, so that impurities and dust are separated from the raw materials, and the screening effect of impurities and dust is improved. A number of exhaust ducts 2012 are equidistantly installed from left to right near the top of the back of the shell 201. Impurities and dust can be sucked through the exhaust ducts 2012, thereby improving the filtering effect of the filter 203 on impurities and dust, and improving production quality. A hose 206 is installed at the bottom of the shell 201 and at the bottom of the weighing hopper 205. The two ends of the hose 206 are respectively connected to the shell 201 and the storage barrel 101. The raw materials that have been accurately weighed can be transported to the inside of the storage barrel 101 through the hose 206, which improves the convenience of use. The discharge port 105, the feed hopper 202 and the weighing hopper 205 are all equipped with electric valves 3. The closing of the discharge port 105, the feed hopper 202 and the weighing hopper 205 can be controlled at any time through the electric valve 3, which improves the convenience of use.

[0025] The working process of the present invention is as follows: first, the granular raw material is put into the feed hopper 202 through an external feeding device, and the electric valve 3 is controlled to open so that the raw material falls onto the filter screen 203 inside the shell 201. The raw material will be separated from the impurities and dust during the rolling process. At the same time, the impurities and dust can be extracted out of the shell 201 through the exhaust duct 2012, so that the screening of the raw material is completed, the influence of the impurities and dust on the production quality is reduced, and the practicality is improved. The raw material that has completed the screening will fall into the weighing hopper 205, and the weight of the raw material will be monitored in real time through the strain gauge sensor 204. Once the required weight is reached, information will be sent to the external control device, so that the external control device controls the electric valve 3 inside the feed hopper 202 to close, so as to complete the precise mixing of the raw materials. At the same time, the electric valve 3 inside the weighing hopper 205 is controlled to open, so that the raw material falls into the storage barrel 10 through the hose 206. 1, and the other various raw materials are accurately mixed according to the above steps, and after being put into the storage barrel 101, the material rack 1022 is driven to rotate by the motor 1021 to stir the raw materials in the storage barrel 101. During the process, high-pressure gas can be input into the channel 103 through the air inlet pipe 104, so that the end of the channel 103 close to the bottom generates suction, and the raw materials at the bottom of the storage barrel 101 are sucked into the channel 103, and sprayed out from the top of the channel 103, and repeated stirring is performed, which greatly reduces the impact on the subsequent fusion step and effectively improves the mixing effect. After the stirring is completed, the work of the air inlet pipe 104 is stopped, and the raw materials can be stored in the storage barrel 101 for a long time; when it is necessary to discharge the material, the electric valve 3 inside the discharge port 105 is controlled to open, and the raw materials are pushed to the discharge port 105 through the scraper 1023 to complete the discharge of the raw materials.
