Description

Technical Field

[0001] The utility model relates to the technical field of product packaging, in particular to a product bagging device. Background Art

[0002] Packaging, a crucial step in the journey from production line to consumer hands, is becoming increasingly important as market competition intensifies and consumer demands diversify. It not only protects products from environmental contamination and damage during transportation and storage, such as dust, moisture, and impact, but also significantly enhances a product's appeal through sophisticated design and ingenious design, becoming a key factor in stimulating consumer purchasing desire. As specialized equipment for this purpose, packaging machines' technological prowess and innovative capabilities are directly linked to product packaging efficiency, quality, and cost.

[0003] Among various packaging formats, bagging is highly favored for its convenience, affordability, and wide applicability. As a key component in bagging automation, bag-feeding equipment greatly improves packaging efficiency and production line automation by automating operations such as bag feeding, bag opening, filling, and sealing. However, despite its widespread industrial application, bag-feeding equipment still has some technical deficiencies that need to be addressed, particularly in gripper design.

[0004] In existing bag-feeding bagging equipment, the jaws, a key component for gripping and positioning bags, are typically designed with a fixed spacing. This design is inadequate for handling bags of varying specifications and sizes. Since bags for the same product vary in size, a fixed jaw spacing often cannot adapt to this variability, leading to problems such as inaccurate bag positioning, unstable gripping, and even bag breakage during the packaging process. Utility Model Content

[0005] Therefore, in order to solve the above-mentioned shortcomings, the present invention provides a product bagging device, including a bag clamping assembly, which clamps both sides of the packaging bag to fix the packaging bag;

[0006] The bag clamping assembly comprises:

[0007] The clamping jaws are provided in two groups, the two groups of clamping jaws are arranged opposite to each other, and the two groups of clamping jaws are connected by a second spring;

[0008] An adjusting component is provided between the two sets of clamping jaws, and drives the clamping jaws to move toward or away from each other through the adjusting component;

[0009] The clamping jaw includes a second roller, which is arranged on the inner side of the clamping jaw;

[0010] The adjusting component comprises:

[0011] Second power unit;

[0012] The lifting plate is driven by the second power device to move linearly in a direction normal to the plane where the two sets of clamps are located. The second roller maintains contact with the first side surface of the lifting plate, and the distance between the first side surfaces increases or decreases linearly.

[0013] The utility model drives the lifting plate to move linearly through a second power device, so that the second roller rolls along the first side surface of the lifting plate. If the distance between the contact point of the second roller and the first side surface gradually increases with the movement of the lifting plate, the clamping claw is driven to move linearly outward under the resistance action of the lifting plate, and the first spring is stretched at this time. If the distance between the contact point of the second roller and the first side surface gradually decreases with the movement of the lifting plate, it moves inward under the restoring action of the first spring, thereby realizing the adjustment of the distance between the clamping claws.

[0014] Furthermore, the clamping jaws include:

[0015] A fixing rod, with a fixing clamp fixedly mounted on one end of the fixing rod;

[0016] a first connecting rod, wherein the middle portion of the first connecting rod is pivotally connected to the fixed rod, the first connecting rod of one set of clamping jaws having one end close to the other set of clamping jaws provided with a first roller, and the other end connected to the fixed rod via a first spring;

[0017] a second connecting rod pivotally connected to an end not provided with the first roller;

[0018] a movable clamping block, the movable clamping block being pivotally mounted on the fixed rod and pivotally connected to the end of the second connecting rod;

[0019] The bagging equipment also includes a claw opening assembly, which includes a first power device and a slider. One side of the slider is in contact with the first roller, and the slider is driven by the first power device to move linearly so that the movable clamping block pivots relative to the fixed rod.

[0020] When the slider is pushed to move by the first power device, the slider acts on one end of the first connecting rod, causing it to rotate around the pivot axis with the fixed rod, and at the same time, drives the second connecting rod to pull the movable clamping block to rotate, so that the movable clamping block is separated from the fixed clamping block. At this time, the first connecting rod will stretch the second spring. When the first power device drives the slider to retract, the first connecting rod drives the first connecting rod to rotate under the restoring action of the second spring, thereby pushing the movable clamping block close to the fixed clamping block, fixing the side of the packaging bag. The structure is simple and easy to maintain.

[0021] Furthermore, the bag clamping assembly and the jaw opening assembly are provided in two groups;

[0022] The bagging device further comprises a moving unit, on which the two sets of bag clamping assemblies and the opening claw assemblies are arranged, and the two sets of bag clamping assemblies and the opening claw assemblies are driven to reciprocate by the moving unit;

[0023] The mobile unit comprises:

[0024] a third power unit;

[0025] The slide is driven by a third power device to move linearly, and the two groups of bag clamping assemblies and claw opening assemblies are installed on the slide.

[0026] The bag clamping assembly and the jaw opening assembly are driven to reciprocate by the moving unit, so that the two groups of bag clamping assemblies and jaw opening assemblies can be replaced alternately at the working point, thereby improving the bag filling efficiency.

[0027] Furthermore, the bagging device further comprises a bag opening unit, and the bag opening unit is correspondingly arranged above the bag clamping assembly;

[0028] The bag opening unit comprises:

[0029] Second power module;

[0030] The vacuum suction cups are provided with two groups, the two groups of vacuum suction cups are arranged opposite to each other, and the second power module drives the two groups of vacuum suction cups to move toward or away from each other.

[0031] The vacuum suction cups absorb the surface of the packaging bag, and the second power module drives the vacuum suction cups to move in opposite directions, pulling the packaging bag open to achieve bag opening.

[0032] Furthermore, the bag opening unit also includes a sixth power device, which drives the vacuum suction cup to move vertically linearly.

[0033] The sixth power device drives the vacuum suction cup to move vertically, thereby facilitating adjustment of the suction position of the vacuum suction cup according to the specifications of the packaging bag.

[0034] Furthermore, the bag opening unit further includes:

[0035] a first power module;

[0036] The bag opening plates are provided with two groups, and the two groups of bag opening plates are arranged opposite to each other between the two groups of vacuum suction cups, and the bag opening plates are driven to move toward or away from each other by the first power device;

[0037] The fifth power device drives the bag opening plate to move vertically linearly.

[0038] After the vacuum suction cup pulls the packaging bag open, the fifth power device drives the bag opening plate to slide vertically so that the bag opening plate is inserted into the packaging bag. Then the first power module drives the bag opening plates to move in opposite directions, thereby keeping the packaging bag in an open state and keeping the bag openings separated.

[0039] Furthermore, the first power module includes:

[0040] fourth power unit;

[0041] The gear is driven to rotate by a fourth power device;

[0042] Racks, which are provided with two groups, are arranged in parallel on opposite sides of the gear and are kept in mesh with the gear, and the bag opening plate is connected to the end of the racks;

[0043] The second power module has the same structure as the first power module.

[0044] The fourth power device drives the gear to rotate, thereby driving the two sets of racks to move linearly. Since the two sets of racks are engaged on opposite sides of the gear, the movements of the two sets of racks are opposite, thereby realizing the toward or away movement of the vacuum suction cup or the bag opening plate. The module has a simple structure and is easy to maintain.

[0045] Furthermore, the bagging device further includes a feeding unit, which is arranged above the bag opening unit and includes:

[0046] Seventh power unit;

[0047] The feed hopper is driven by the seventh power device to move vertically linearly.

[0048] After the bag is opened, the seventh power device drives the feed hopper to slide down vertically and insert it into the packaging bag, and then guides the product into the packaging bag to avoid spilling the product.

[0049] The utility model has the following advantages:

[0050] The utility model drives the lifting plate to move linearly through a second power device, so that the second roller rolls along the first side surface of the lifting plate. If the distance between the contact point of the second roller and the first side surface gradually increases with the movement of the lifting plate, the clamping claw is driven to move linearly outward under the resistance action of the lifting plate, and the first spring is stretched at this time. If the distance between the contact point of the second roller and the first side surface gradually decreases with the movement of the lifting plate, it moves inward under the restoring action of the first spring, thereby realizing the adjustment of the distance between the clamping claws.

[0066] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0067] In this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "includes," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0068] As described in the background, existing bag-feeding bagging equipment typically uses fixed spacing between the jaws, a key component for gripping and positioning bags. This design is inadequate for handling bags of varying specifications and sizes. Since bags for the same product vary in size, a fixed jaw spacing often cannot accommodate this variation, leading to problems such as inaccurate bag positioning, unstable gripping, and even bag breakage during the packaging process.

[0069] Example 1:

[0070] Therefore, in order to solve the above technical problems of the prior art, this embodiment provides a product bagging device, such as Figure 1 As shown, it includes a bag clamping assembly 200, which clamps both sides of the packaging bag to fix the packaging bag;

[0071] like Figure 2 、 3 As shown, the bag clamping assembly includes:

[0072] The clamping jaws 210 are provided in two groups, the two groups of clamping jaws are arranged opposite to each other, and the two groups of clamping jaws are connected by a second spring 230;

[0073] An adjusting component 240 is provided between the two sets of clamping jaws and drives the clamping jaws to move toward or away from each other;

[0074] The clamping jaw includes a second roller 217, which is arranged on the inner side of the clamping jaw;

[0075] The adjusting component comprises:

[0076] Second power unit 241;

[0077] The lifting plate 242 is driven by a second power device to move linearly in a direction normal to the plane where the two sets of clamps are located. The second roller maintains contact with the first side surface of the lifting plate, and the distance between the first side surfaces increases or decreases linearly.

[0078] The lifting plate is driven to move linearly by the second power device, so that the second roller rolls along the first side surface of the lifting plate. If the distance between the contact point of the second roller and the first side surface gradually increases with the movement of the lifting plate, the clamping jaws are driven to move linearly outward under the resistance of the lifting plate, and the first spring is stretched at this time. If the distance between the contact point of the second roller and the first side surface gradually decreases with the movement of the lifting plate, it moves inward under the recovery action of the first spring, thereby realizing the adjustment of the distance between the clamping jaws.

[0079] For example, Figure 3 As shown, the side of the lifting plate close to the second roller in this embodiment can be designed as follows Figure 3 In the triangle shape shown, the second roller contacts both sides of the triangle end, and the second power device drives the lifting plate to rise vertically, that is, the clamping claw moves outward. Of course, it can also be designed into an inverted triangle shape, a trapezoidal shape, etc.

[0080] In this embodiment, the second power device includes but is not limited to a pneumatic cylinder, an electric cylinder, a hydraulic cylinder or other devices capable of driving the lifting plate to move linearly.

[0081] Example 2:

[0082] This embodiment provides a structure of a clamp based on the embodiment 1. In this embodiment, as Figure 4 As shown, the clamping jaws include:

[0083] A fixing rod 211, at one end of which a fixing clamp 215 is fixedly mounted;

A first roller 216 is provided at one end of the first connecting rod of one set of jaws, which is close to the other set of jaws, and the other end is connected to the fixed rod via a first spring 218;

[0085] A second connecting rod 213, pivotally connected to an end not provided with the first roller;

[0086] a movable clamping block 214, which is pivotally mounted on the fixed rod and pivotally connected to the end of the second connecting rod;

[0087] like Figure 1As shown, the bagging device also includes a claw opening assembly 100, which includes a first power device and a slider. One side of the slider is kept in contact with the first roller, and the slider is driven by the first power device to move linearly so that the movable clamping block pivots relative to the fixed rod.

[0088] In this embodiment, the slider is driven to move by the first power device. The slider acts on one end of the first connecting rod to rotate around the pivot axis with the fixed rod. At the same time, it drives the second connecting rod to pull the movable clamp to rotate so that the movable clamp is separated from the fixed clamp. At this time, the first connecting rod will stretch the second spring. When the first power device drives the slider to retract, the first connecting rod drives the first connecting rod to rotate under the restoring action of the second spring, thereby pushing the movable clamp close to the fixed clamp, fixing the side of the packaging bag. The structure is simple and easy to maintain.

[0089] In this embodiment, the first power device includes but is not limited to a cylinder, an electric cylinder, a hydraulic cylinder or other devices that can drive the push block to move linearly.

[0105] In this embodiment, the bag opening unit may further include a mounting portion, and the bag opening unit as a whole is fixedly mounted on the frame through the mounting portion.

[0106] In this embodiment, if Figure 7 As shown, the bag opening unit further includes a sixth power device 450, which drives the vacuum suction cup to move vertically linearly.

[0107] The sixth power device drives the vacuum suction cup to move vertically, thereby facilitating adjustment of the suction position of the vacuum suction cup according to the specifications of the packaging bag.
