Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to a dust-cutting bag clamping mechanism. Background Art

[0002] Packaging equipment refers to equipment that can complete all or part of the product and commodity packaging process. The packaging process includes the main processes such as filling, wrapping, and sealing, as well as related processes before and after, such as cleaning, stacking, and disassembly. In addition, packaging also includes processes such as metering or stamping on the package. Using mechanical packaging products can improve productivity, reduce labor intensity, adapt to the needs of large-scale production, and meet the requirements of cleanliness and hygiene.

[0003] The bag clamping mechanism of the existing packaging equipment generates a large amount of dust when filling material particles, and the extra material that falls off the cage mouth after unloading is also easy to fall into the packaging bag, resulting in inaccurate weight accuracy of the unloading. Utility Model Content

[0004] Based on the above problems, the utility model aims to provide a dust-trapping bag clamping mechanism which can reduce floating dust in the air during the production process, make the production environment cleaner, increase production safety and improve the weighing accuracy of unloading materials.

[0005] In view of the above problems, the following technical solutions are provided: a dust-trapping bag clamping mechanism, comprising a mounting plate and a lower hopper fixed on the mounting plate, the lower hopper being provided with a feed end and a discharge end, and also comprising a dust-proof component and a bag clamping component, the dust-proof component comprising a rotating shaft arranged through the discharge end, a flap door located in the discharge end and adapted thereto, a bearing seat fixed on the outer wall of the lower hopper, a swing block connected to one end of the rotating shaft, and a driving cylinder for controlling the rotation of the rotating shaft through the swing block, the bearing seat being provided with two bearings respectively connected to the two ends of the rotating shaft, a fixed arm being connected to the mounting plate, one end of the driving cylinder being transmission-connected to the swing block, and the other end being fixed to the fixed arm through a cylinder seat The bottom of the flap door is provided with a connecting seat adapted to the rotating shaft, and the driving cylinder drives the flap door to flip through the swing block to control the rotating shaft to realize the opening and closing of the discharge port; the bag clamping assembly comprises a first clamping arm, a second clamping arm and a control cylinder, and the end corners of the mounting plate are provided with ear seats, and the top ends of the first clamping arm and the second clamping arm are respectively rotatably fixed on the corresponding ear seats, the bottom ends of the first clamping arm and the second clamping arm are located below the mounting plate, and the ends are fixed with clamping plates, one end of the control cylinder is connected to the first clamping arm through a Y joint, and the other end is connected to the second clamping arm through a cylinder seat, and the bag clamping assembly is symmetrically arranged in two groups relative to the axial direction of the lower hopper.

[0006] In the above structure, the control cylinder is started to control the first clamping arm and the second clamping arm to swing in opposite directions relative to the ear seat, so that the clamping plates on the first clamping arm and the second clamping arm are separated. After the packaging bag is sleeved on the outer wall of the discharge end of the lower hopper, the control cylinder drives the cylinder shaft to retract, and controls the first clamping arm and the second clamping arm to swing toward each other relative to the ear seat, so that the clamping plates on the first clamping arm and the second clamping arm clamp the bag mouth of the packaging bag. The driving cylinder drives the swing block to control the rotating shaft to drive the flap door to flip, so that the flap door is in a vertical state relative to the discharge end, and the flap door separates the discharge end into two discharge ports. After the feeding end starts to feed, the material is discharged from the two discharge ports. The material is filled into the packaging bag through the discharge port, thereby reducing the floating dust in the air during the production process, making the production environment cleaner and reducing the risk of dust explosion, making the production safer; after the filling is completed, the drive cylinder swing block controls the rotating shaft to drive the flap door to flip in the opposite direction, so that the flap door is reset to a horizontal position, which plays a role in isolating the inner cavity of the lower hopper from the inner cavity of the packaging bag, thereby preventing the dust in the packaging bag from pouring into the lower hopper, pushing up the cleanliness of the environment, and preventing the extra material from being spilled from the top into the packaging bag, affecting the weighing accuracy, thereby reducing the extra waste of material and helping manufacturers reduce costs. By setting two sets of bag clamping components, the stability and reliability of the bag clamping can be improved, and the reliability of the material discharge of the utility model is improved. By setting the swing block, it is convenient for the drive cylinder to control the rotating shaft to drive the flap door to swing, which improves the reliability of the utility model. By setting the fixed arm, it is convenient for the fixed installation of the drive cylinder, and the stability of the swing of the driving shaft driven by the drive cylinder is further improved.

[0007] The utility model is further configured that a silicone pad is sleeved on the rotating shaft and is located on a side of the bearing seat facing the lower hopper.

[0008] The above structure can improve the tightness of the bearing seat fixed to the outer wall of the lower hopper, thereby improving the stability of the bearing seat and the reliability of the dustproof component.

The bolt locks the opening slot between the first fixing block and the extension block through the fixing hole, plays a role of clamping the rotating shaft, and the opening slot can also improve the convenience of connection between the connecting seat and the flap door.

[0011] The utility model is further configured that two connecting seats are arranged at intervals in the axial direction of the rotating shaft.

[0012] The above structure can further improve the stability of the flap door and enhance the reliability of the utility model.

[0013] The utility model is further configured that connecting rods are connected between the first clamping arms and the second clamping arms of the two groups of bag clamping assemblies, and both ends of the connecting rods are located close to the clamping plates.
