DETAILED DESCRIPTION
[0020] In order to make the above features and advantages of the present invention more understandable, embodiments are given below with reference to the accompanying drawings for detailed description, but the present invention is not limited thereto.
[0021] refer to Figures 1 to 4
[0022] A lifting powder filling mechanism with stepless adjustment of opening size comprises a collecting hopper 10, a lower port of the collecting hopper is provided with a lifting fixed frame 21, a pair of filling gates 22 located outside the lower port of the collecting hopper are hinged on the fixed frame, and the upper parts of the filling gates are hinged to the fixed frame via rotating shafts 27; a filling port is formed between the lower ends of the pair of filling gates, and an elastic member 23 for closing the filling port is provided between the upper parts of the pair of filling gates, and an opening and closing adjustment mechanism for driving the pair of filling gates to adjust the size of the filling port is installed on the collecting hopper, so that the lifting and lowering of the fixed frame realizes the lifting and lowering of the filling port, and the size of the filling port is adjusted by the opening and closing adjustment mechanism.
[0023] In this embodiment, the collecting hopper is a hollow tube structure with a larger upper portion and a smaller lower portion. The lower port of the collecting hopper is a rectangular tube structure. Driven by gravity, the material can flow in through the upper opening and out through the lower opening to achieve the filling function.
[0024] In this embodiment, a lifting guide column 25 is vertically fixed to one side of the collecting hopper through a fixed plate 24, and a lifting slide 26 that slides with the lifting guide column is mounted on the lifting guide column, and the lifting slide is fixedly connected to the fixed frame. The lifting guide column and the lifting slide cooperate to form a linear drive element such as an electric slide or a pneumatic slide, preferably a three-axis cylinder. The lifting slide slide slides relatively along the lifting guide column, thereby driving the filling gate, elastic parts and other parts to move up and down at the same time.
[0025] In this embodiment, the opening and closing adjustment mechanism includes a cam guide column 32 fixed to the front side of the collecting hopper via a mounting plate 31, a cam slide 33 slidably matched with the cam guide column is provided on the cam guide column, a cam plate 34 is fixed on the cam slide, and a driving wheel 35 is installed on the filling gate plate. The lower two sides of the cam plate are inclined surfaces, and the driving cam cooperates with the inclined surfaces. The cam guide column is fixed to the collecting hopper and does not move, and the cam slide can slide relatively along the cam guide column, thereby driving the cam plate to move synchronously, and then the filling port is opened when the cam slide rises.
[0026] In this embodiment, the cam guide column and the cam slide cooperate to form a linear drive element such as an electric slide or a pneumatic slide, and a three-axis cylinder is preferably used.
[0027] In this embodiment, in order to limit the rising stroke of the cam slide, a suspension plate 36 is installed on the front side of the collecting hopper, and an adjusting push rod 37 located on one side of the cam slide is vertically installed on the suspension plate. A limit plate 38 cooperating with the adjusting push rod is fixed to the lower part of the cam slide, thereby limiting the distance that the cam plate pushes the driving wheel to rotate, so as to control the opening size of the filling port.
[0028] In this embodiment, the adjusting push rod is a linear drive element such as an electric cylinder, an electric push rod or an electric slide.
[0029] In this embodiment, the elastic member is a spring or rubber band whose two ends are respectively fixedly connected to the corresponding filling gates, so as to pull a pair of filling gates to keep them close to each other. The driving wheel is connected to the filling gates via a fixed shaft 39, and the two ends of the elastic member are respectively connected to the corresponding fixed shafts.
[0030] Working principle: The filling port is driven by the lifting slide to approach the packaging container such as packaging bags, barrels or boxes placed below; then the cam slide moves upward, driving the cam plate to push the driving wheels on both sides, driving the filling port to open; at this time, the adjustment push rod limits the movement distance of the cam slide, thereby limiting the opening size of the filling port; then the material is filled through the internal cavity of the collecting hopper. After filling, the cam slide drives the cam plate to move downward, and the filling port is closed under the pulling force of the elastic member, and then driven by the lifting slide to rise away from the packaging container below.
[0031] If the present invention discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the fixed connection to each other can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except where it is obviously impossible to use an one-piece molding process).
[0032] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in the above utility model include states or shapes that are approximate, similar or close thereto.
[0033] Any component provided by the utility model can be assembled from multiple separate components, or can be a separate component manufactured by an integrated molding process.
[0034] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention.
