Description

Technical Field

[0001] This utility model relates to a weighing device for mixing liquid feed. Background Technology

[0002] Current liquid feed is generally produced by mixing and processing various liquids and some powder components. The conventional production method is to directly calculate the weight of each component based on the packaging weight. However, since the weights on the packaging of each component are inaccurate, once mass production begins, the weights of each component can easily accumulate from small errors to cause large errors, resulting in the feed failing to meet the expected standards. At the same time, in the transition area of ​​the production process, due to the lack of weighing equipment, the weight of the mixed liquid output from the mixing tank also has a large error. Utility Model Content

[0003] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art and provide a feed liquid mixing and weighing device with reasonable design. It weighs the amount of liquid feed of different components and mixes them through the weighing sensor on the mixing tank, so as to avoid the error in the overall ratio caused by the superposition of weight errors on the component packaging during mass production. At the same time, the weighing transition device weighs the mixed liquid output from the mixing tank to reduce the output error.

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0030] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0031] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0032] like Figure 1-4 As shown, a liquid feed mixing and weighing device includes a high-level frame A1 erected on the ground, with a placement opening A2 on the high-level frame. A mixing vessel A3 is installed in the placement opening, and the lower part of the mixing vessel extends downward from the placement opening. A weighing transition device A4 is connected to the lower part of the mixing vessel via a pipeline. The output of the weighing transition device is connected to a lower-level packaging mechanism via a pipeline. In use, liquid feed of different components is mixed in the mixing vessel, and then output to the weighing transition device for weighing via a pipeline. Finally, a certain weight of the mixed liquid is transported to the existing lower-level packaging mechanism for packaging or to the lower-level mixing mechanism for mixing.

[0033] In this embodiment, in order to achieve weight control when feeding each component, the mixing vessel includes a vessel body A5, and a plurality of mixing vessel lugs A6 are evenly distributed around the outer wall of the vessel body. A contact seat A7 is provided on the upper layer of the frame corresponding to the mixing vessel lugs. A weighing sensor A8 is sandwiched between the mixing vessel lugs and the contact seat. The amount of material fed is controlled by sensing the change in the weight of the vessel body by the weighing sensor.

[0034] In this embodiment, in order to achieve mixing, a stirring shaft A9 is rotatably connected inside the vessel. Stirring blades A10 are provided on the outer periphery of the stirring shaft. The upper end of the stirring shaft extends through the top of the vessel. A drive motor A11 is installed on the top of the vessel to drive the extended end of the stirring shaft to rotate. The stirring shaft is driven to rotate by the drive motor, thereby achieving mixing.

[0035] In this embodiment, to realize the feeding and discharging of the vessel, a liquid inlet A12 is provided on the top of the vessel, and a cover plate A13 is hinged to the liquid inlet. A discharge port A14 is provided at the bottom of the vessel, and a U-shaped adapter A15 is installed on the discharge port. The uppermost end of the U-shaped adapter is the input end, and the two lower ends are the output ends. The input end of the U-shaped adapter is connected to the discharge port. An existing switch valve A16 is provided in one output end of the U-shaped adapter, and the other output end is connected to the weighing transition device through a pipeline with a flow control valve A17. More specifically, a switch valve is provided in the vertical output end of the U-shaped adapter, and a pipeline with a flow control valve is connected to the weighing transition device at the inclined output end. In use, the vertical output end is used to open when cleaning the vessel to facilitate drainage during cleaning, and the inclined output end is used for normal conveying.

[0036] In this embodiment, to achieve output weighing after liquid mixing, the weighing transition device includes a support frame A18, which is installed on the ground and located below the upper level of the frame. A weighing vessel A19 is installed on the support frame, and weighing lugs A20 are symmetrically arranged on the outer periphery of the weighing vessel. The weighing lugs abut against the frame of the support frame. A weighing sensor is arranged between the weighing lugs and the frame of the support frame. An input port is opened on the top of the weighing vessel. One output end of the U-shaped adapter is connected to the input port via a pipeline with an existing flow control valve. In use, the flow control valve is opened, and the mixed liquid is sent from the mixing vessel to the weighing vessel. When approaching the target weight, the channel size in the flow control valve gradually decreases until the weighing sensor detects that the weighing vessel has completely reached the target weight. At this time, the flow control valve is completely closed to avoid the weight of the mixed liquid in the weighing vessel exceeding the standard due to the failure to close the input end of the weighing vessel in time.

[0037] like Figure 5-13 As shown, this embodiment also includes a material lifting device B1, and symmetrically arranged sliding columns B2 on the ground. The sliding columns penetrate the upper level of the frame and extend upward. A loading mechanism B3 is slidably connected between the two sliding columns. A lifting clearance opening B4 is provided on the upper level of the frame corresponding to the loading mechanism. An anti-falling mechanism B5 is provided on the sliding columns corresponding to the position where the loading mechanism stops on the upper level of the frame. Protective fence mechanisms B6 are installed on the lifting clearance opening and on the ground corresponding to the loading mechanism. In use, the loading mechanism loads the materials located on the ground, and then the loading mechanism is lifted to transport the materials to the upper level, reducing manual handling by climbing stairs and improving production efficiency. At the same time, the anti-falling mechanism can prevent the loading mechanism from suddenly falling due to the failure of the drive device. The protective fence mechanism surrounds the placement point of the loading mechanism on the ground and the lifting clearance opening to prevent personnel from accidentally falling from the lifting clearance opening or from standing under the falling loading mechanism due to lack of attention, thus facilitating safe production.

[0038] In this embodiment, to achieve the sliding of the loading mechanism, the loading mechanism includes a loading base plate B7. Vertical support columns B8 are symmetrically welded to the middle of the left and right sides of the loading base plate. Several inclined reinforcing support rods B9 are also welded between the support columns and the same side edge of the loading base plate. That is, several inclined reinforcing support rods are provided on the front and rear sides of the support columns. The reinforcing support rods reinforce the connection between the support columns and the loading base plate, and also surround the left and right sides of the loading base plate to prevent the material from falling from the left and right sides during the lifting process due to insecure placement. A lifting crossbar B10 is placed horizontally between the tops of the two support columns. At least one slider B11 is provided at intervals from top to bottom on the side of the support column. A vertical slide rail B12 is provided on the side of the sliding column corresponding to the slider. The lifting is achieved by the cooperation of the slider and the slide rail.

[0039] In this embodiment, to drive the sliding of the loading mechanism, the tops of the two sliding columns are connected by a supporting beam B13. A winding bracket B14 is installed on the ground next to one of the sliding columns. A winding roller B15, driven by a motor, is rotatably connected to the winding bracket. A lifting rope B16, which is used to drive the lifting of the loading mechanism, is wound on the winding roller. The lifting rope can be a steel cable. The motor drives the winding roller to rotate, thereby driving the winding or unwinding of the lifting rope. Several guide wheels B17 are rotatably connected at intervals along the length of the sliding column and the supporting beam, near the side of the sliding column and the upper part of the supporting beam. Guide wheel mounting brackets are provided on the sliding column and the supporting beam corresponding to the guide wheels. The guide wheels are rotatably connected to the guide wheel mounting brackets via a rotating shaft. A fixed hook B18 for attaching the end of the lifting rope is provided on the top of the sliding column away from the winding bracket. The end of the lifting rope is guided and attached to the fixed hook by a guide wheel. That is, the end of the lifting rope is guided upward by the guide wheel at the bottom of the side of the sliding column, and then guided to the fixed hook by the guide wheel on the support beam. A vertical through hole B19 is opened in the middle of the support beam. A section of the lifting rope on the support beam extends downward through the through hole to form a U-shaped hook placement rope B20. A hook assembly B21 is slidably connected to the U-shaped area of ​​the hook placement rope. The support beam is hung on the hook assembly. By winding or unwinding the lifting rope, the length of the U-shaped hook placement rope decreases or increases, thereby raising or lowering the hook assembly and thus raising or lowering the loading mechanism.

[0040] In this embodiment, to enable the support beam to be hung on the hook assembly, the hook assembly has the following structure: the hook assembly includes two symmetrically arranged mounting plates B22, which are connected by welding several connecting rods B23. Alternatively, they can be connected by existing methods such as bolts. A grooved wheel B24 is rotatably connected between the upper parts of the two mounting plates via a rotating shaft. The grooved wheel is hung on the U-shaped area of ​​the hook placement rope. An existing hook B25 is provided between the lower parts of the two mounting plates. A hanging groove B26 is provided on the middle part of the support beam corresponding to the hook. The hanging groove of the support beam is hung on the hook, thus enabling the support beam to be hung on the hook assembly.

[0041] In this embodiment, to improve the safety of the equipment, the anti-fall mechanism includes an anti-fall fixing bracket B27, on which at least one vertical sleeve B28 is installed. This sleeve can consist of two concentric vertical sleeves. A rotating rod B29 is rotatably connected inside each vertical sleeve. Alternatively, one rotating rod can be fitted into multiple vertical sleeves. A limiting pin B30 is horizontally placed on the rotating rod. Guide holes B31 are provided on the outer wall of each vertical sleeve corresponding to the two ends of the limiting pin. The two ends of the limiting pin slide into the corresponding guide holes. A limiting plate B32 is installed on the lower end of the rotating rod. The two extreme rotation positions of the limiting pin correspond to the limiting plate fully rotating under the load base plate and the limiting plate completely leaving the load base plate. Simultaneously, the anti-fall mechanism can prevent the load mechanism from suddenly falling due to a failure of the drive device.

[0042] In this embodiment, to prevent personnel from accidentally falling through the lifting clearance opening or from unknowingly standing under the falling loading mechanism, and to facilitate safe production, the protective fence mechanism includes vertical fence posts B33 at the four corners. The vertical fence posts of the protective fence mechanism located at the lifting clearance opening are welded to the elevated floor, and the vertical fence posts of the protective fence mechanism located on the ground are fixed to the ground. The adjacent vertical fence posts on the left and right sides, as well as the adjacent vertical fence posts on the rear side, are connected by several horizontal fence posts B35 welded at intervals from top to bottom, achieving enclosure in three directions. The two adjacent vertical fence posts on the front side are connected by several horizontal fence posts B35. A front fence B36 is snapped between the straight fence bars. When materials need to be placed or removed on the loading mechanism, the protective fence mechanism can be opened by opening the front fence. The specific structure of the front fence is as follows: the front fence includes horizontal bars B37 arranged parallel to each other vertically. The horizontal bars are connected by several vertical bars 38 arranged at intervals. The connection method can be welding. The two ends of the horizontal bars are provided with downward vertical inserts B39. The two vertical fence bars on the front side are provided with insert sleeves B40 corresponding to the vertical inserts. The opening or closing of the protective fence mechanism is realized by the insertion and disengagement between the vertical inserts and the insert sleeves.

[0043] In this embodiment, since there is a risk that the material may detach from the front and rear sides of the loading base plate due to unstable placement during the lifting process, a fixed protective railing B41 is welded between the rear sides of the two support columns on the loading base plate. This fixed protective railing can be installed by first welding it to the rear side of the loading base plate, and then welding the two sides of the fixed protective railing to the rear sides of the two support columns via bent rods. A flip-up movable guardrail B42 is hinged between the front sides of the two support columns. The flip-up movable guardrail allows material to enter and exit when it is necessary to place or remove material on the loading mechanism. Specifically, the flip-up movable guardrail includes L-shaped flip rods B4 symmetrically arranged on the left and right sides. 3. The horizontal part of the L-shaped flipping rod is on top and the vertical part is on the bottom. The horizontal end of the L-shaped flipping rod is hinged to the support column on the same side. Several horizontal connecting rods B44 are arranged between the vertical parts of the two L-shaped flipping rods from top to bottom. The ends of the vertical parts of the two L-shaped flipping rods abut against the front side of the loading base plate. The flipping of the L-shaped flipping rod drives the entire flipping movable guardrail to flip. At the same time, the support column can be equipped with existing buckles for locking the horizontal part of the L-shaped flipping rod, and the loading base plate can also be equipped with existing buckles for locking the bottom horizontal connecting rod, so as to fix the flipping movable guardrail when it is opened or closed. Of course, it is also possible to fix it directly by tying with rope.
