Description

Technical Field

[0001] This utility model relates to the technical field of packaging equipment, and in particular to a bag-covering device for packaging bags. Background Technology

[0002] After the packaging bags are produced, multiple packaging bags need to be stacked and packaged. However, stacking multiple packaging bags makes them loose and difficult to bag and package at once.

[0003] Existing packaging bag bagging devices, such as the packaging bag bagging device disclosed in utility model patent application number 201821974595.0, mainly include an outer bag providing mechanism, an inner bag providing mechanism, a bagging mechanism, and a control mechanism. The outer bag providing mechanism is used to provide the outer bag to the bagging station under the control of the control mechanism. The inner bag providing mechanism is used to provide the inner bag to the bagging waiting position under the control of the control mechanism. The bagging mechanism is used to open the outer bag at the bagging station under the control of the control mechanism and then put the inner bag at the bagging waiting position into the outer bag. In use, the outer bag opening mechanism includes a fourth Z-axis translation unit that can move along the Z-axis and a bag opening suction cup provided on the fourth Z-axis translation unit. The bag opening suction cup is located above the bagging station and corresponds to the opening end of the outer bag. The inner bag pushing mechanism includes a second X-axis translation unit that can move along the X-axis and a bag pushing cylinder provided on the second X-axis translation unit.

[0004] However, it is difficult for staff to control the force when pressing the packaging bag, and it is easy to use too much force, causing damage to the packaging bag and device. Moreover, it is inconvenient to remove the packaging bag after it is put on top, and it is easy to cut the palm. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a packaging bag covering device that not only facilitates the cushioning of the depth of workers' footsteps, avoiding damage to equipment and packaging bags caused by excessive force, but also facilitates the pushing out of other packaging bags together after the first packaging bag is put on, avoiding scratching the workers' palms.

[0006] This utility model discloses a packaging bag covering device, including a support mechanism; it also includes a pressing mechanism, a stepping mechanism, a buffer mechanism, and a reminder mechanism. The pressing mechanism is installed on the support mechanism and works with the support mechanism to press the packaging bag tightly. The stepping mechanism is installed on the pressing mechanism and drives the pressing mechanism to press down. The buffer mechanism is installed on the support mechanism to prevent the stepping mechanism from stepping too deeply. The reminder mechanism is installed on the buffer mechanism to remind the worker to step in the correct position. The worker places the folded packaging bag between the support mechanism and the pressing mechanism, and then steps on the stepping mechanism. The stepping mechanism drives the pressing mechanism to press down. The buffer mechanism limits the stepping depth of the stepping mechanism. The reminder mechanism reminds the worker that the stepping is in place. The worker then covers the packaging bag outside the support mechanism and the pressing mechanism. The pressing mechanism pushes the packaging bag outward, making it convenient for the worker to seal the packaging bag.

[0007] Preferably, the support mechanism includes three sets of anti-slip legs, a base, a hollow column, and a tray. The bottom ends of the three sets of anti-slip legs are connected to the ground, the bottom end of the base is connected to the top end of the three sets of anti-slip legs, the bottom end of the hollow column is connected to the top end of the base, and the tray is installed on the hollow column. Workers place the folded packaging bags on the tray. By setting up three sets of anti-slip legs, the stability of the device is improved, and the device is prevented from shaking when the stepping mechanism is stepped on.

[0008] Preferably, the pressing mechanism includes an extended support, a connecting frame, a pressure plate, two sets of electric cylinders, and a soft push plate. The extended support is mounted on a hollow column, the connecting frame is rotatably mounted on the extended support, the pressure plate is mounted on the connecting frame, both sets of electric cylinders are mounted on the pressure plate, and the soft push plate is mounted on the top of the two sets of electric cylinders. The stepping mechanism pulls the connecting frame to rotate downwards, the pressure plate presses down on the packaging bag, and the stacked packaging bag is pressed tightly. The worker puts the packing bag between the tray and the pressure plate, the two sets of electric cylinders push the soft push plate, and the soft push plate pushes the packaging bag and the packing bag out together, pushing the stacked packaging bag out together with the packing bag.

[0009] Preferably, protective covers are also attached to the edges of the tray and the pressure plate; by attaching protective covers, the tray and pressure plate can prevent workers from scratching their palms when removing the packaging bags.

[0010] Preferably, the pedal mechanism includes a pedal rod, a pedal, a first spring, and a pull rod. The pedal rod is rotatably mounted on a hollow column, the pedal is mounted on the pedal rod, the first spring is connected between the pedal rod and the hollow column, and the pull rod is connected between the pedal rod and the connecting frame. When the operator steps on the pedal, the pedal causes the pedal rod to press down, and the pedal rod pulls the connecting frame downward through the pull rod to apply pressure. When the operator releases the pedal, the first spring pulls the pedal rod back to its original position, and the pedal rod pushes the connecting frame and the pressure plate up through the pull rod.

[0011] Preferably, the buffer mechanism includes a limiting box, two sets of second springs, and shock-absorbing pads. The limiting box is installed on the base, and both sets of second springs are installed inside the limiting box. The bottom end of the shock-absorbing pads is connected to the top end of the two sets of second springs. When the pedal is pressed down, it squeezes the shock-absorbing pads, and the shock-absorbing pads squeeze the two sets of second springs, thus buffering and limiting the pedal to prevent the device from being damaged due to excessive force exerted by the operator.

[0012] Preferably, the indicator mechanism includes a first patch, a second patch, a control box, a red light, and a green light. The first patch is installed on the pedal, the second patch is installed on the shock-absorbing pad, the control box is installed on the hollow column, the red light is installed on the control box, and the green light is installed on the control box. When the first patch and the second patch come into contact, the control box illuminates the red light to remind the worker that the pedal is in place and should not be stepped on further. When the first patch and the second patch separate, the control box illuminates the green light to remind the worker that the stacked packaging bags can be placed on the tray.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the staff places the stacked packaging bag between the support mechanism and the pressing mechanism, and then steps on the stepping mechanism. The stepping mechanism drives the pressing mechanism to press down. The buffer mechanism limits the stepping depth of the stepping mechanism, and the prompting mechanism reminds the staff that they have stepped in place. The staff puts the packaging bag on the outside of the support mechanism and the pressing mechanism, and the pressing mechanism pushes the packaging bag outward, making it convenient for the staff to seal the packaging bag.
