Abstract
Description
Technical Field
[0001] The utility model relates to a bag clamping and filling mechanism with adjustable feeding width. Background Art
[0002] At present, in order to improve the packaging efficiency, the packaging machine is used to pack the items into bags. This packaging method is also widely used in food processing industries such as rice and sugar. The existing bag clamping and filling device can only be used for fixed-size bags, and the filling port is suitable for bags of various specifications and widths. If the bags are replaced, the bag clamping and filling device must also be replaced. This not only causes great inconvenience in production and maintenance, but also requires bags of different specifications to be equipped with specific bag clamping and filling devices, which increases production costs and the difficulty of equipment maintenance, seriously affecting the production efficiency of the enterprise; in addition, if the bag clamping and filling device corresponding to bags of different sizes is not replaced, but a small filling port is used, when replacing large-size bags, the filling speed will be relatively slow due to the small filling port, affecting work efficiency.

[0013] Figure 2 It is a side view of an embodiment of the utility model;
[0014] Figure 3 For the utility model embodiment Figure 2 . DETAILED DESCRIPTION
[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0016] Example: As attached Figure 1-3 As shown, in this embodiment, a bag clamping and filling mechanism with adjustable feeding width is provided, including a feed hopper 1 and fixed plates 2 arranged at the front and rear positions of the feed hopper output end, and rotatable bag supporting folding plates 3 are arranged between the two sides of the fixed plates, the upper parts of the two bag supporting folding plates are hinged to the fixed plates, and the lower parts of the two bag supporting folding plates and the two fixed plates form a filling port 4 with an adjustable size.
[0017] During operation, the size of the filling port is adjusted according to the width of the packaging bag to be filled. When the size of the filling port needs to be adjusted, the upper parts of the bag-supporting folding plates on the corresponding sides are driven to rotate along their hinge points by the two bag-supporting electric push rods, so as to adjust the width of the lower parts of the two bag-supporting folding plates to adapt to the size of the packaging bag to be filled; after adjusting the width, the bag is put on the filling port, and after the filling button is started, the two bag clamping cylinders extend out, driving the bag clamping rubber layer A to press the bag clamping rubber layer B, so that the bag is limited between the bag clamping rubber layers A and B, thereby pressing the bag on both sides of the filling port. After the filling is completed, the two bag clamping cylinders retract, and the bag clamping rubber layer A and the bag clamping rubber layer B are opened and separated, so that the packaging bag naturally falls away from the filling port.
[0018] It is worth mentioning here that when adjusting the width of the two bag-supporting folding plates, a certain amount of exit space needs to be reserved on the outside of the filling port, which is beneficial for manual bagging so that the fingers can retain enough exit space after bagging at the filling port.
[0019] A bag clamping assembly 5 is arranged on the outer side of the fixing plate.
[0020] In the embodiment of the utility model, the bag clamping assembly includes bag clamping rubber layer plates A51 arranged in front of and behind the fixed plate, and a bag clamping rubber layer plate B52 is arranged on one side of the fixed plate close to the bag clamping rubber layer plate A.
[0021] In the embodiment of the utility model, bag clamping cylinders 53 are provided in front and rear of the feed hopper, and the sides of the two bag clamping cylinders away from their output shafts are respectively hinged to the front and rear of the feed hopper, and extension rods 54 are provided in front and rear of the fixed plate. The output shaft of the bag clamping cylinder is hinged with a swing frame 55, the swing frame is hinged with the extension rod, and the bag clamping rubber layer A is fixed on the swing frame.
[0022] In an embodiment of the utility model, bag-supporting electric push rods 6 are provided on both sides of the feed hopper to drive the bag-supporting folding plate to rotate along its hinge point. The side of the bag-supporting electric push rod away from its output end and the output end of the bag-supporting electric push rod are respectively connected to the outside of the feed hopper and the outside of the bag-supporting folding plate through a bracket 7.
[0023] In the embodiment of the utility model, the cross-sections of the two bag-supporting folding plates are both U-shaped, wherein the width of the U-shaped groove of one bag-supporting folding plate is slightly smaller than the width of the other bag-supporting folding plate, or the two identical bag-supporting folding plates are staggered.
[0024] like Figure 3 As shown, the two bag-supporting folding plates can be completely rotated and stored between the two fixing plates, thereby adapting to the width of smaller bags.
[0025] In the embodiment of the utility model, the output end of the feed hopper and the upper end of the fixed plate are connected via two connecting plates 8, the two connecting plates are respectively fixed below the feed hopper and above the fixed plate, and a feed discharge port is provided in the middle of the two connecting plates.
[0026] In the embodiment of the utility model, the fixed plate is wide at the top and narrow at the bottom, and a discharge channel is formed between the two bag-supporting folding plates and the two fixed plates. The discharge channel has an inlet at the top and an outlet at the bottom, and the rest is closed.
[0027] Unless otherwise stated, any technical solution disclosed in the above utility model, if it discloses a numerical range, then the disclosed numerical range is a preferred numerical range. Any technician in the field should understand that the preferred numerical range is only a numerical value with a more obvious technical effect or representative value among many feasible numerical values. Since there are too many numerical values to be exhaustive, the utility model discloses only some numerical values to illustrate the technical solution of the utility model, and the numerical values listed above should not constitute a limitation on the scope of protection of the utility model.
[0028] If the words "first", "second" and so on are used in this article to limit components, those skilled in the art should know that the use of "first" and "second" is only for the convenience of description to distinguish the components. Unless otherwise stated, the above words have no special meaning.
[0029] At the same time, if the above-mentioned utility model discloses or involves components or structural parts that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connected by bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except when it is obviously impossible to use an one-piece molding process).
[0030] 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.
[0031] 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.
