Examples

Referring to fig. 1-4 and 6, a material bagging and clamping mechanism 600 provided in this embodiment includes a clamping arm group 601 and a bag stretching rod group 602, where the clamping arm group 601 and the bag stretching rod group 602 respectively act on different positions of a material bag mouth, and the bag mouth is not a bag mouth side of a material bag, but includes an upper portion of the material bag near the bag mouth. The arm-clamping set 601 includes a first arm-clamping 6011 and a second arm-clamping 6012, where one ends of the first arm-clamping 6011 and the second arm-clamping 6012 are movable ends 6013, that is, one ends of the first arm-clamping 6011 and the second arm-clamping 6012 can be movably connected with other platforms, such as a hinge, a universal connection, a sliding connection, a telescopic connection, etc., so that the entire first arm-clamping 6011 and the second arm-clamping 6012 can move based on the respective movable ends 6013.

In addition, the other ends of the first arm 6011 and the second arm 6012 are both clamping ends 6014, that is, the other ends of the first arm 6011 and the second arm 6012 are used for clamping objects, for example, clamping a pocket of a material bag, which can be realized by configuring a clamping assembly or forming a clamping position by itself, and the clamping manner can be two-side extrusion clamping, clamping adsorption, adhesive adsorption, and the like. Specifically, the first clamping arm 6011 and the second clamping arm 6012 can make the respective clamping ends 6014 approach to or separate from each other within the movement range of the respective movable ends 6013, so as to clamp or release the material bag mouth; that is, the movable end 6013 controls the clamping arms to move, particularly, the clamping arms on two sides move relatively close to or far away from each other, so that the material bag opening can be clamped when the clamping arms are relatively close to each other, and the material bag opening can be released when the clamping arms are far away from each other, so that the material bag clamping and releasing operation is completed.

Likewise, the bag tightening rod group 602 adopts a connection principle similar to the clamp arm group 601, specifically, the bag tightening rod group 602 includes a first bag tightening rod 6021 and a second bag tightening rod 6022, one ends of the first bag tightening rod 6021 and the second bag tightening rod 6022 are moving ends 6023, that is, one ends of the first bag tightening rod 6021 and the second bag tightening rod 6022 can be movably connected with other platforms, such as hinging, universal connection, sliding connection, telescopic connection, etc., so that the whole first bag tightening rod 6021 and the second bag tightening rod 6022 can move based on the respective moving ends 6023.

The other ends of the first bag stretching rod 6021 and the second bag stretching rod 6022 are force application ends 6026, and can interact with other articles, so that the force application ends 6026 of the first bag stretching rod 6021 and the second bag stretching rod 6022 interact with two sides of the articles, and the purpose of abutting and tightly abutting is achieved, for example, when the two inner side walls of the flexible material bag opening are abutted, the material bag opening can be stretched flat or straight. Specifically, the first bag stretching rod 6021 and the second bag stretching rod 6022 can make the respective force application ends 6026 approach to or separate from each other within the movement range of the respective movement ends 6023, so as to tighten or loosen the bag mouth of the material bag; that is, the force application ends 6026 of the first bag stretching rod 6021 and the second bag stretching rod 6022 can be separated from each other under the dominant action of the moving end 6023, so that the two inner side walls of the bag opening of the material bag are mutually abutted to achieve the purpose of stretching the bag opening, and the force application ends 6026 of the first bag stretching rod 6021 and the second bag stretching rod 6022 can be mutually close to each other, so that the bag opening of the material bag is loosened and the material bag can be naturally separated.

Through the technical scheme, the tightening operation can be performed after the packaging bag opening is clamped, so that the packaging bag opening is restored to a smooth posture, the packaging bag opening is positioned by the follow-up procedure so as to finish sewing or sealing operation, and the situation that the packaging bag opening is straightened by manually intervening or one more procedure is avoided, so that higher operation efficiency cannot be achieved. It should be noted that, an included angle is formed between the direction in which the clamping ends 6014 approach or depart from each other and the direction in which the force application ends 6026 approach or depart from each other, that is, the moving direction of the clamping ends 6014 is inconsistent with the moving direction of the force application ends 6026, so that on one hand, the moving interference can be avoided, and on the other hand, a better tightening effect of the bag mouth is convenient to obtain in order to adapt to the shape of the bag mouth.

In this embodiment, a hinge is disposed at one end of each of the first arm 6011 and the second arm 6012 as the movable end 6013, that is, the arm movement is realized by means of a hinge, for example, a planar hinge, a universal hinge, etc., which is illustrated in this embodiment. The other ends of the first arm 6011 and the second arm 6012 are provided with a bag clamping block as the clamping end 6014, that is, the clamping end 6014 is configured or formed to clamp a bag of the material bag.

Considering that the bag clamping block can form stable flexible clamping on the bag mouth of the material bag, the movement of the bag stretching rod does not influence the stability of the flexible clamping. That is, in order to ensure the stability of the bag opening of the material bag clamped by the bag clamping blocks, the bag stretching rods can conveniently form a moving track which is close to or far away from each other, and the embedded grooves 6018 which can accommodate the first bag stretching rods 6021 and/or the second bag stretching rods 6022 are formed on one sides of the two groups of bag clamping blocks which are close to each other. That is, when the insertion grooves 6018 of the bag clamping blocks are spliced with each other, at least one of the first bag stretching rod 6021 and the second bag stretching rod 6022 (both of which are accommodated in the insertion groove 6018 if symmetrically arranged) can be accommodated, and the phenomenon that the clamping stability is deteriorated due to the fact that the first bag stretching rod 6021 and the second bag stretching rod 6022 need to be arranged at the material bag mouth to facilitate the action of both side walls of the bag mouth does not occur, which results in the fact that the two groups of bag clamping blocks cannot be tightly spliced.

In addition, since the material bag mouth adopts the mode of flexible centre gripping, need rely on the frictional force between flexible cotton and the wrapping bag surface to form stable centre gripping effect, in order to make this centre gripping effect promote further, on the basis that the both sides bag piece that presss from both sides can closely splice each other, in the one side that two sets of bag pieces are close to each other, one is offered flutedly 6017, and another shaping has the lug 6016 that matches with this flutedly 6017 to form the centre gripping after making two sets of bag pieces are close to each other and splice the anticreep clearance of material bag mouth. That is, two groups of bag clamping blocks can form a step-type anti-falling gap by utilizing the insertion and splicing mode of the grooves 6017 and the projections 6016, so that bending clamping can be formed at the clamping position of the bag opening when the bag opening of the material bag is clamped, and the phenomenon that the material bag is easily separated from the clamping is prevented.

On the basis of the above, in order to enable the mutual movement between the first arm 6011 and the second arm 6012 to accommodate an automated operation, a first telescopic mechanism 6015 is disposed between the first arm 6011 and the second arm 6012 such that the first arm 6011 and/or the second arm 6012 can swing in the hinge direction of the hinge. That is, it means that the first telescopic mechanism 6015 can swing at least one of the first arm 6011 and the second arm 6012 in the hinge direction with respect to the other, so as to be closer to or farther from each other. The first telescopic mechanism 6015 is, for example, a linear motion mechanism (a rack and pinion, a ball screw, a sliding rail with a sliding block, etc.) or a telescopic element (an electric rod, a telescopic cylinder, etc.), and two ends of the first telescopic mechanism 6015 are respectively hinged to the first arm 6011 and the second arm 6012, so as to achieve the purpose of automatic control that the first arm 6011 and the second arm 6012 approach or separate from each other.

Similarly, in an embodiment, in order to enable the first bag stretching rod 6021 and the second bag stretching rod 6022 to meet the requirement of the automation operation, the device further comprises a second telescopic mechanism 6024 for driving the moving ends 6023 of the first bag stretching rod 6021 and the second bag stretching rod 6022 to swing, and the second telescopic mechanism 6024 aims to enable one bag stretching rod to move towards or away from the other bag stretching rod, namely when the second telescopic mechanism 6024 controls the first bag stretching rod 6021 and/or the second bag stretching rod 6022 to move towards or away from each other, the force application ends 6026 of the corresponding moving bag stretching rods can continuously act on the inner side walls of the material bag opening, so that the two force application ends 6026 can tighten the material bag opening. That is, the second telescopic mechanism 6024 controls at least one of the first bag stretching rod 6021 and the second bag stretching rod 6022 to move, when the two are in a state of moving away from each other, the force application ends 6026 of the two can continuously act with the inner side wall of the bag opening of the material bag, the purpose of stretching the bag opening is achieved, and otherwise, the bag opening is released when the two are close to each other.

The second telescopic mechanism 6024 adopts a linear motion mechanism (a gear rack, a ball screw, a sliding block and a sliding rail, etc.) or a telescopic element (an electric rod, a telescopic cylinder, etc.), etc., and can be synchronously connected with the first bag stretching rod 6021 and the second bag stretching rod 6022, namely hinged between the two, or can adopt a form of configuring the same control source to form two groups of telescopic control members, and the two groups of telescopic control members are respectively hinged with the first bag stretching rod 6021 and the second bag stretching rod 6022 so as to achieve the purpose of independent or synchronous control. Of course, considering the motion interference of the actual working position of the second telescopic mechanism 6024, in this embodiment, two sets of telescopic control members are adopted to avoid the motion interference with the first telescopic mechanism 6024, that is, one set of telescopic control members is connected with one side bag stretching rod. Specifically, the telescopic control piece comprises a telescopic cylinder, a hinge 6025 and a joint bearing, wherein the fixed end of the telescopic cylinder is hinged with the rest platform, the movement track plane of the first telescopic mechanism 6024 is staggered, the joint bearing is integrated at the telescopic end of the telescopic cylinder, one end of a shell of the joint bearing is connected with the end part of the bag stretching rod, and the other end of the shell of the joint bearing is hinged with the external platform through the hinge 6025, so that the purpose that the bag stretching rod can reciprocate along the hinging direction is achieved.

In view of clamping both sides of the bag mouth, a space is left in the middle of the bag mouth to perform operations such as filling, suction, blowing, etc., and in some embodiments, the clamping arm groups 601 have two groups, and the two groups of clamping arm groups 601 are arranged side by side based on the positions of the first bag stretching rod 6021 and the second bag stretching rod 6022. That is, each group of clamping arms 601 is arranged at one side of a single group of bag stretching rods, so that a gap is formed between the two groups of clamping arms 601, and the middle of the bag mouth of the packaging bag is conveniently left for other operations. The two clamping arm groups 601 correspond to the positions of the first bag stretching rod 6021 and the second bag stretching rod 6022 respectively, so that the two clamping arm groups 601 and the bag stretching rod group 602 form square positions which interact with the bag opening of the packaging bag, the bag opening of the packaging bag can be better acted to carry out the operation flow in a specified posture, and meanwhile, the clamping arm groups 601 and the bag stretching rods can form a tightly matched posture.

In a specific embodiment, the first clamp arm 6011 and the second clamp arm 6012 of the two clamp arm groups 601 may be connected by a connecting rod, so as to ensure the consistency of the actions of the two clamp arm groups 601. On the basis of the scheme of configuring the two groups of clamping arm groups 601, the embedded grooves 6018 which can accommodate the corresponding side bag stretching rods are formed in the sides, close to each other, of the two groups of clamping arm groups 601, namely, the two bag clamping blocks representing one group of clamping arm groups 601 are used for clamping the bag stretching rods on one side, so that the two groups of clamping arms 601 are in a more tightly matched posture with the first bag stretching rods 6021 and the second bag stretching rods 6022, particularly, as shown in fig. 3 and 4, a micro-seam clamping state can be formed, and the reliability of clamping of material bags is ensured.

The present embodiment also provides a material bagging and clamping assembly, please refer to fig. 5 and 6, which includes a mounting table 700 and the material bagging and clamping mechanism 600, wherein the material bagging and clamping mechanism 600 at least includes a clamping arm group 601 and a bag stretching rod group 602 to achieve a minimum structural combination of clamping and tightening of a bag opening.

The mounting table 700 is provided with a bag clamping cylinder 701 for positioning a material bag opening, that is, the bag clamping cylinder 701 can interact with the material bag opening, so that a material bag opening positioning function is realized, for example, the middle of the material bag opening extends into the middle of the material bag opening, so that operations such as filling, sucking, blowing and the like can be conveniently performed on the material bag through the bag clamping cylinder 701. The movable ends 6013 of the first arm 6011 and the second arm 6021 are each hinged to the mounting table 700 (specifically, the hinge may be implemented to hinge), and the movable ends 6023 of the first bag stretching rod 6021 and the second bag stretching rod 6022 are each hinged to the mounting table 700 (specifically, the hinge 6025 may be implemented to hinge). The first arm 6011, the second arm 6012, the first bag stretching rod 6021 and the second bag stretching rod 6022 are disposed around the bag clamping cylinder 701, so that the first arm 6011, the second arm 6012, the first bag stretching rod 6021 and the second bag stretching rod 6022 can be tightly spliced when clamping the packaging bag, and a clamping gap capable of stably clamping the packaging bag is formed between the first arm 6011, the second arm 6012, the first bag stretching rod 6021 and the second bag stretching rod 6022 and the bag clamping cylinder 701.

In order to further improve the above-mentioned clamping stability effect, the clamping ends 6014 of the first clamping arm 6011 and the second clamping arm 6012 have a bonding surface for bonding the bag-clamping cylinder 701, that is, the shape of one side of the clamping end 6014 is adapted to the shape of the surface of the bag-clamping cylinder 701, so as to form a matched bonding form, thereby achieving the purpose of forming a stable clamping gap.

The working principle of the material bagging and clamping assembly is as follows: after the material bag is sleeved at the discharge port of the bag clamping cylinder 701, the first clamping arm 6011 and the second clamping arm 6012 of the clamping arm group 601 respectively clamp the material bag stably, at this time, the first clamping arm 6021 and the second clamping arm 6022 are in the storage state as shown in fig. 5, when the material bag needs to be separated from the bag clamping cylinder 701, the first clamping arm 6011 and the second clamping arm 6012 are mutually separated, at the same time, the first clamping arm 6021 and the second clamping arm 6022 are mutually separated, and it is ensured that after the first clamping arm 6011 and the second clamping arm 6012 are separated from the material bag port, the first clamping arm 6021 and the second clamping arm 6022 can clamp the bag port of the material bag, and then the first clamping arm 6021 and the second clamping arm 6022 are mutually close to each other when the bag port is clamped tightly or is in the flat state, so that the material bag can be naturally separated in the flat state, for example, in the process, the first clamping arm 6021 and the second clamping arm 6022 act in the width direction, and the second clamping arm 6022 act in the flat state, and the two sides of the bag port can be easily restored.
