Description

Technical Field

[0001] The invention relates to the technical field of packaging, and in particular to a positioning and clamping device for a powder packaging bag. Background Art

[0002] In the technical field of powder packaging, after the powder is packaged by a packaging machine, it will be transported to a stacking station through a conveyor roller line, and then the packaged powder packaging bags need to be transferred to a forklift bottom plate for stacking. The invention with the authorization announcement number CN220316589U discloses a powder packaging bag stacking device, which includes a clamping component, and the clamping component includes two stretching claws to clamp the powder packaging bag. However, the clamping component has the following disadvantages when clamping the packaging bag: 1. When the clamping component clamps the powder packaging bag, the powder packaging bag is clamped from above, and the powder packaging bag will be deformed after being clamped, which is inconvenient for stacking, especially multi-layer stacking; 2. When the clamping component clamps the packaging bag, the clamping may be unstable; 3. If the packaging bag is out of position when the clamping component is clamping, it is difficult for the clamping component to clamp accurately. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a positioning and clamping device for a powder packaging bag, which can position and then clamp the powder packaging bag conveyed by a conveyor roller line, ensuring that each clamping action is more accurate.

[0004] To solve the above technical problems, the technical solution of the present invention is: a positioning and clamping device for a powder packaging bag, comprising a connecting frame for connecting to a manipulator, a first support and a second support being horizontally slidably installed on the connecting frame, the first support and the second support being driven by a first linear power device and a second linear power device respectively, a plurality of positioning rods arranged at intervals for easy insertion into the gap between adjacent conveying rollers being fixedly installed on the first support and the second support respectively, the positioning rods being vertically arranged, a first rotating shaft and a second rotating shaft being rotatably installed on the first support and the second support respectively, a plurality of clamping rods arranged at intervals for easy insertion into the gap between adjacent conveying rollers being fixed on the first rotating shaft and the second rotating shaft, and a first deflection power device and a second deflection power device for driving the first rotating shaft and the second rotating shaft to deflect are also installed on the connecting frame.

[0005] As a preferred solution, the clamping rod includes a vertical rod portion, which is fixed on the first rotating shaft or the second rotating shaft. A horizontal rod portion is provided at the bottom of the clamping rod. The horizontal rod portion is perpendicular to the vertical rod portion, and the horizontal rod portions cooperate with each other to jointly support the bottom of the powder packaging bag.

[0006] As a preferred solution, a horizontal connecting rod portion is provided at the upper end of the vertical rod portion, and a matching groove adapted to the first rotating shaft or the second rotating shaft is provided on the horizontal connecting rod portion, and the matching groove of the horizontal connecting rod portion is placed on the first rotating shaft or the second rotating shaft and fixed to the first rotating shaft or the second rotating shaft by bolts.

[0007] As a preferred solution, the ends of the positioning rod and the clamping rod are both configured as circular portions.

[0008] As a preferred solution, the number of the positioning rods is the same as the number of the clamping rods, and each positioning rod is in side-by-side contact with a vertical rod portion of a clamping rod.

[0009] As a preferred solution, the first support and the second support have the same structure and are mirror-imaged, the first support includes an L-shaped connecting plate, the horizontal plate portion of the connecting plate is horizontally slidably mounted on the connecting frame via a first slide, the positioning rod is fixed to the vertical plate portion of the connecting plate via bolts, and suspension plates are also fixed to both ends of the horizontal plate portion via bolts, and the first rotating shaft is rotatably mounted on the suspension plate.

[0010] As a preferred solution, the vertical plate portion is provided with hollow holes.

[0011] As a preferred solution, the first deflection power device is a first deflection cylinder, a cylinder bracket is fixed on the horizontal plate, the middle part of the first deflection cylinder is hinged on the cylinder bracket, the piston rod of the first deflection cylinder is connected to the deflection arm, and the deflection arm is fixed on the first rotating shaft.

[0012] After adopting the above technical scheme, the effect of the present invention is as follows: since the positioning and clamping device of the powder packaging bag includes a connecting frame for connecting to the manipulator, a first support and a second support are horizontally slidably installed on the connecting frame, and the first support and the second support are driven by a first linear power device and a second linear power device respectively, and a plurality of positioning rods arranged at intervals for convenient insertion into the gap between adjacent conveying rollers are fixedly installed on the first support and the second support respectively, and the positioning rods are vertically arranged, and a first rotating shaft and a second rotating shaft are rotatably installed on the first support and the second support respectively, and a plurality of clamping rods arranged at intervals for convenient insertion into the gap between adjacent conveying rollers are fixed on the first rotating shaft and the second rotating shaft, and a driving mechanism for driving the first rotating shaft and the second rotating shaft is also installed on the connecting frame. The first deflection power device and the second deflection power device are used to deflect the first rotating shaft and the second rotating shaft; firstly, the first linear power device and the second linear power device are used to drive the first support and the second support to slide horizontally relative to each other outward, so that the spacing between the positioning rods and the spacing between the clamping rods are expanded, and then the positioning rods are inserted into the gaps between the conveying rollers, and then the first support and the second support are driven to slide horizontally relative to each other inward, so that the positioning rods can contact and position the powder packaging bags on the conveying rollers, and then the first deflection power device and the second deflection power device drive the first rotating shaft and the second rotating shaft to deflect, so that the clamping rods can effectively clamp the powder packaging bags; the positioning and clamping device can position the powder packaging bags transported by the conveying roller line and then clamp them, ensuring that each clamping action is more accurate.

[0013] Furthermore, since the clamping rod includes a vertical rod portion, the vertical rod portion is fixed on the first rotating shaft or the second rotating shaft, a horizontal rod portion is provided at the bottom of the clamping rod, the horizontal rod portion and the vertical rod portion are perpendicular to each other, and the horizontal rod portions cooperate with each other to jointly support the bottom of the powder packaging bag; the horizontal rod portion forms a supporting surface, which can effectively support the powder packaging bag, with a simple structure and reliable clamping.

[0014] Since a horizontal connecting rod portion is provided at the upper end of the vertical rod portion, a matching groove adapted to the first rotating shaft or the second rotating shaft is provided on the horizontal connecting rod portion, and the matching groove of the horizontal connecting rod portion is placed on the first rotating shaft or the second rotating shaft and fixed to the first rotating shaft or the second rotating shaft by bolts; the matching groove can be conveniently installed on the first rotating shaft and the second rotating shaft, thereby improving the installation efficiency.

[0015] Furthermore, since the ends of the positioning rod and the clamping rod are both arranged as round parts, the round parts improve safety and effectively protect the powder packaging bag during positioning and clamping.

[0016] Since the number of the positioning rods is the same as the number of the clamping rods, each positioning rod is in parallel contact with the vertical rod portion of a clamping rod, ensuring that they can all be inserted into the gap between the conveying rollers, thereby ensuring the accuracy of positioning and clamping.

[0017] Since the structures of the first support and the second support are the same and are mirror-imaged, the first support includes an L-shaped connecting plate, the horizontal plate portion of the connecting plate is horizontally slidably installed on the connecting frame through a first slide, the positioning rod is fixed to the vertical plate portion of the connecting plate by bolts, and the two ends of the horizontal plate portion are also fixed with hanging plates by bolts, and the first rotating shaft is rotatably installed on the hanging plate; ensuring that the positioning rod and the clamping rod can move synchronously, and driving the connecting plate to move is simple and reliable, thereby improving the use effect.

[0018] Furthermore, since the vertical plate portion is provided with hollow holes, the weight of the connecting plate can be effectively reduced, thereby improving practicality.

[0019] Since the first deflection power device is the first deflection cylinder, a cylinder bracket is fixed on the horizontal plate portion, the middle part of the first deflection cylinder is hinged on the cylinder bracket, the piston rod of the first deflection cylinder is connected to the deflection arm, and the deflection arm is fixed on the first rotating shaft; when the deflection arm swings, the first deflection cylinder also needs to perform synchronous deflection to ensure accurate driving.
