Description

Technical Field

[0001] The present invention relates to the technical field of industrial equipment for production, and in particular to a masterbatch raw material mixing and storage device. Background Art

[0002] Functional masterbatch raw materials are mainly used in the manufacturing process of plastic products. As additives, they can change the performance and application characteristics of plastic products. Functional masterbatch combines coloring and specific functions in one, and can significantly improve the physical, chemical and mechanical properties of plastic products, thereby expanding their application scope and improving product quality. In the production process of plastic products, precise mixing of its raw materials is required.

[0003] The structures of common precise mixing devices for functional masterbatch raw materials are relatively simple. During the mixing process, impurities and dust in the raw materials must be screened out. Otherwise, the impurities and dust mixed in the raw materials will seriously affect the production quality of plastic products. And the existing devices have poor mixing effects on various raw materials during the mixing process, which will affect the subsequent fusion step and have insufficient practicability. Summary of the Invention

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

[0005] The technical solution adopted by the present invention to solve its technical problems is: a masterbatch raw material mixing and storage device, including a storage mechanism, and a mixing mechanism is installed at the top of the storage mechanism;

[0006] The storage mechanism includes a storage barrel. A driving component is installed near the top inside the storage barrel. A channel is opened near the left side inside the storage barrel. An air inlet pipe is installed near the bottom on the left side of the storage barrel. A discharge port is opened at the bottom of the storage barrel;

[0007] The mixing mechanism includes a housing. A plurality of feed hoppers are arranged equidistantly at the top of the housing. A filter screen is installed near the top inside the housing. Strain gauge sensors are symmetrically installed near the front and back of the inner bottom of the housing. A weighing hopper is installed at the top of the two strain gauge sensors.

[0008] Furthermore, as a preferred solution of the present invention, the driving component includes a motor. The output end of the motor and inside the storage barrel is fixedly connected with a material stirring frame. A plurality of scraping plates are welded around the periphery of the end of the material stirring frame near the bottom; the scraping plates rotate with the rotation of the material stirring frame; when the end face of the scraping plate 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 scraping plate blocks the port at the bottom of the channel.

[0009] The technical effect of adopting the above further solution is that the rotation of the motor can drive the material distributing rack to rotate, thereby stirring the raw materials put into the storage barrel. The scraper can push the raw materials falling at the bottom of the storage barrel towards the channel entrance, or push the raw materials towards the discharge port after stirring, facilitating the discharging work and improving the usability.

[0010] Furthermore, as a preferred solution of the present invention, a metal mesh is installed inside the intake pipe near the end close to the storage barrel, and the intake pipe is communicated with the channel.

[0011] The technical effect of adopting the above further solution is that the metal mesh can prevent raw materials from entering the intake pipe. The intake pipe can input high-pressure gas into the channel, thereby generating suction at one 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 settling at the bottom and improving the mixing effect.

[0012] Furthermore, as a preferred solution of the present invention, several support columns are welded to the bottom of the housing, and the support columns are fixedly connected to the storage barrel.

[0013] The technical effect of adopting the above further solution is that through the fixed connection between the support columns and the storage barrel, the housing can be made more firm and the usability can be improved.

[0014] Furthermore, as a preferred solution of the present invention, the filter screen is installed in an inclined manner towards the front and is fixed inside the housing by bolts.

[0015] The technical effect of adopting the above further solution is that through the inclined installation of the filter screen, the raw materials can roll above it during the falling process, separating the impurities and dust from the raw materials and improving the screening effect on the impurities and dust.

[0016] Furthermore, as a preferred solution of the present invention, several exhaust pipes are installed equidistantly from left to right near the top of the back of the housing.

[0017] The technical effect of adopting the above further solution is that the impurities and dust can be sucked through the exhaust pipes, thereby improving the filtering effect of the filter screen on the impurities and dust and improving the production quality.

[0018] Furthermore, as a preferred solution of the present invention, a hose is installed at the bottom of the housing and at the bottom of the weighing hopper, and both ends of the hose are communicated with the housing and the storage barrel respectively.

[0019] The technical effect of adopting the above further solution is that the accurately weighed raw materials can be conveyed into the storage barrel through the hose, improving the usability.

[0020] Furthermore, as a preferred embodiment of the present invention, electric valves are installed inside the discharge port, the feed hopper, and the weighing hopper.

[0021] The technical effect of adopting the above further solution is that the opening and closing of the discharge port, the feed hopper, and the weighing hopper can be controlled at any time through the electric valves, improving the convenience of use.

[0022] The beneficial effects of the present invention are as follows: it solves the defects in the background technology. Through the design of the storage mechanism and the mixing mechanism, and through the design of the filter screen in cooperation with the exhaust duct, impurities and dust in the raw materials can be screened quickly and efficiently, reducing the impact of impurities and dust on the production quality and improving the practicability. Through the use of the air inlet duct in cooperation with the channel, the raw materials settled at the bottom can be re-transported to the top of the feeding rack for repeated stirring, greatly reducing the impact on the subsequent fusion step, effectively improving the mixing effect while being able to store materials, facilitating the implementation of subsequent processes.

[0028] Now, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so they only show the components related to the present invention.

[0029] Such as Figures 1-4A masterbatch raw material mixing and storage device shown includes a storage mechanism 1, and a mixing mechanism 2 is installed at the top of the storage mechanism 1. The storage mechanism 1 includes a storage barrel 101, a driving component 102 is installed near the top inside the storage barrel 101, a channel 103 is opened near the left side inside the storage barrel 101, an intake pipe 104 is installed near the bottom on the left side of the storage barrel 101, and a discharge port 105 is opened at the bottom of the storage barrel 101. The mixing mechanism 2 includes a housing 201, a plurality of feed hoppers 202 are arranged equidistantly at the top of the housing 201, a filter screen 203 is installed near the top inside the housing 201, strain gauge sensors 204 are symmetrically installed near the front and back of the inner bottom of the housing 201, and a weighing hopper 205 is installed at the top of the two strain gauge sensors 204.

[0030] Such as Figures 1-4As shown in the figure, the driving assembly 102 includes a motor 1021. At the output end of the motor 1021 and inside the storage bucket 101, there is a material stirring rack 1022 fixedly connected. Around the periphery of the end of the material stirring rack 1022 near the bottom, several scraping plates 1023 are welded. By the rotation of the motor 1021, the material stirring rack 1022 can be driven to rotate, thereby stirring the raw materials put into the storage bucket 101. Through the scraping plates 1023, the raw materials falling at the bottom of the storage bucket 101 can be pushed towards the entrance of the channel 103, and the scraping plates 1023 rotate with the rotation of the material stirring rack 1022; when the end face of the scraping plate 1023 rotates to the bottom port of the channel 103 during the rotation process and completely blocks the end face of the bottom port of the channel 103, the scraping plate 1023 can block the bottom port of the channel 103, so that the raw materials can better flow towards the upper outlet of the channel 103 to complete the spraying effect. At the same time, the bottom of the scraping plate 1023 is closely attached to the bottom of the bucket, and it can also push the raw materials towards the discharge port 105 after the stirring is completed, facilitating the discharging work and improving the use convenience. Inside the end of the air inlet pipe 104 near the storage bucket 101, a metal mesh 1041 is installed. The air inlet pipe 104 is connected to the channel 103. Through the metal mesh 1041, raw materials can be prevented from entering the air inlet pipe 104. Through the air inlet pipe 104, high-pressure gas can be input into the channel 103, so that a suction force is generated at one end of the channel 103 near the bottom, sucking the raw materials at the bottom of the storage bucket 101 into the channel 103 and spraying them out from the top of the channel 103, preventing the raw materials from sinking to the bottom and improving the mixing effect. At the bottom of the housing 201, several support columns 2011 are welded, and the support columns 2011 are fixedly connected to the storage bucket 101. Through the fixed connection between the support columns 2011 and the storage bucket 101, the housing 201 can be made more firm and the use stability can be improved. The filter screen 203 is installed in an inclined manner towards the front, and is fixed inside the housing 201 by bolts. Through the inclined installation of the filter screen 203, the raw materials can roll above it during the falling process, separating the impurities and dust from the raw materials and improving the screening effect on the impurities and dust. At the back of the housing 201 near the top, several exhaust pipes 2012 are installed equidistantly from left to right. Through the exhaust pipes 2012, the impurities and dust can be sucked, thereby improving the filtering effect of the filter screen 203 on the impurities and dust and improving the production quality. At the bottom of the housing 201 and at the bottom of the weighing hopper 205, a hose 206 is installed. The two ends of the hose 206 are respectively connected to the housing 201 and the storage bucket 101. Through the hose 206, the accurately weighed raw materials can be transported into the storage bucket 101, improving the use convenience. Electric valves 3 are installed inside the discharge port 105, the feed hopper 202, and the weighing hopper 205. Through the electric valves 3, the opening and closing of the discharge port 105, the feed hopper 202, and the weighing hopper 205 can be controlled at any time, improving the use convenience.

[0031] Workflow of the present invention: First, the granular raw materials are put into the interior of the feed hopper 202 through an external feeding device. By controlling the opening of the electric valve 3, the raw materials fall onto the filter screen 203 inside the housing 201. During the rolling process, the raw materials will be separated from impurities and dust. At the same time, through the exhaust duct 2012, the impurities and dust can be extracted from the housing 201, completing the screening work of the raw materials, reducing the impact of impurities and dust on the production quality, and improving the practicability. The raw materials that have completed the screening work will fall into the weighing hopper 205. The strain gauge sensor 204 will monitor the weight of the raw materials in real time. Once the required weight is reached, it will send a message to the external control device, and then the external control device will control the closing of the electric valve 3 inside the feed hopper 202 to complete the precise mixing of the raw materials. At the same time, it controls the opening of the electric valve 3 inside the weighing hopper 205, so that the raw materials fall into the storage barrel 101 through the hose 206. After accurately mixing other various raw materials according to the above steps and putting them into the storage barrel 101, the motor 1021 drives the material stirring frame 1022 to rotate to stir the raw materials inside 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 a suction force is generated at one end of the channel 103 close to the bottom, sucking the raw materials at the bottom of the storage barrel 101 into the channel 103 and spraying them out from the top of the channel 103 for repeated stirring, greatly reducing the impact on the subsequent fusion step and effectively improving 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 discharging is required, the electric valve 3 inside the discharge port 105 is controlled to open, and the raw materials are pushed towards the discharge port 105 through the scraper 1023 to complete the discharge work of the raw materials.

Various examples do not constitute a limitation to the essential content of the present invention. Those of ordinary skill in the technical field can make modifications or deformations to the previously described specific implementation manners after reading the specification without departing from the essence and scope of the invention.
