Description

Technical Field

[0001] This utility model relates to the field of packaging bag folding technology, and in particular to a folding device for the production of medical packaging bags. Background Technology

[0002] Existing packaging bag folding devices, in order to ensure the folding accuracy of packaging bags and prevent them from being damaged, often use abutments to clamp the packaging bag and set up adjustable folding components to fold the packaging bag more accurately. However, they cannot measure the size of the packaging bag or control the folding width. For example, a packaging bag folding device disclosed in Chinese Patent Application No. CN201821841528.1 has an adjustment mechanism that ensures that the fold line of the unfolded packaging bag is at the center of the upper and lower abutments. The lifting folding plate can just abut at the height of the fold line. The sliding slider can adjust the relative position of the folding plate with the upper and lower abutments, making it easier to align and abut at the fold line of the packaging bag more accurately, resulting in a neater fold. However, it cannot measure the size of the packaging bag or control the folding width. Utility Model Content

[0003] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a folding device for the production of medical packaging bags. The device involves starting a fan motor to rotate the fan, which blows air onto the packaging bag on the side of the pressure roller. The air is blown onto the packaging bag before the initial folding by the pressure roller, ensuring the accuracy of the folding effect and preventing damage. This results in a neater fold. The air blowing component also blows away dust from the surface of the packaging bag, preventing dust from falling into the bag. The device can also rotate a rotating plate counterclockwise, placing one side of the packaging bag against the side of the rotating plate. Starting a lead screw motor rotates the lead screw, which drives a push plate to press against the other side of the packaging bag. The size of the packaging bag can be easily seen through the scale lines on the side surface of the push plate and support plate. Rotating the rotating plate to remove it from obstructing the packaging bag, and starting the lead screw motor again, the lead screw drives the push plate to move. The push plate pushes the packaging bag a distance according to the required folding width, thus achieving the measurement of the packaging bag size and the control of the folding width.

[0004] This utility model also provides a folding device for producing medical packaging bags, comprising: a base, a vertical plate fixedly connected to the upper surface of the base, a fan motor fixedly connected to the side surface of the vertical plate, a fan fixedly connected to the output end of the fan motor, a pressure block fixedly connected to the side surface of the vertical plate, a pressure roller motor fixedly connected inside the pressure block, and a pressure roller fixedly connected to the output end of the pressure roller motor; a support plate, a rotating plate rotatably connected inside the support plate, a lead screw motor fixedly connected inside the support plate, a lead screw fixedly connected to the output end of the lead screw motor, and a push plate provided on the surface of the lead screw. Using the above components, the fan motor is activated to rotate the fan, blowing air onto the packaging bag on the side of the pressure roller. This bending of the bag before the initial fold by the pressure roller ensures the accuracy of the folding effect, prevents damage, and results in a neater fold. The airflow also blows away dust from the bag's surface, preventing it from falling inside. The rotating plate can be rotated counter-clockwise, placing one side of the bag against the plate. The lead screw motor is then activated, rotating the lead screw to drive the push plate against the other side of the bag. The size of the bag can be easily seen through the scale lines on the side surface of the support plate. Rotating the plate to remove it from obstruction and activating the lead screw motor again moves the push plate, pushing the bag a distance according to the required folding width, thus achieving measurement of the bag's size and control of the folding width.

These components provide support for the power source used to clamp and transport components, facilitating the measurement of packaging bag dimensions.

[0007] According to the present invention, a folding device for producing medical packaging bags includes a roller motor fixedly connected inside the vertical plate, and a lower roller fixedly connected to the output end of the roller motor. These components provide power for the rotation of the roller and transmit the power to the lower roller.

[0008] According to the folding device for producing medical packaging bags described in this utility model, the lower roller is rotatably connected to the inside of the support plate, and a lower gear is fixedly connected to the side surface of the lower roller.

Through these components, rotational power is transmitted to the upper gear and then to the upper gear.

[0010] According to the present invention, a folding device for producing medical packaging bags includes an upper roller rotatably connected to the vertical plate and the inner side plate, with the upper roller positioned directly above the lower roller. These components enable the upper roller to rotate normally.

[0011] According to the present invention, a folding device for producing medical packaging bags includes a pressure block and a pressure roller located on the side surface of a support plate, and a pressure plate fixedly connected to the inside of the push plate and the side surface of the vertical plate. These components facilitate the folding of the packaging bag by the folding component and prevent the packaging bag from being blown away by the blowing component. Beneficial effects

[0012] Compared with existing technologies, this utility model, by starting the fan motor to rotate the fan, blows air onto the packaging bag on the side of the pressure roller. The bag is bent before the pressure roller initially folds the edge, ensuring the accuracy of the folding effect and preventing damage. This results in a neater fold. The air blowing component also blows away dust from the surface of the packaging bag, preventing dust from falling into the bag. The rotating plate can be rotated counterclockwise, placing one side of the packaging bag against the side of the rotating plate. The screw motor is started to rotate the screw, which drives the push plate to press against the other side of the packaging bag. The size of the packaging bag can be easily seen by the scale lines on the side surface of the push plate and the support plate. Rotating the rotating plate to remove the obstruction of the packaging bag, the screw motor is started to rotate the screw, which drives the push plate to move. The push plate pushes the packaging bag a certain distance according to the required folding width, thus realizing the measurement of the packaging bag size and the control of the folding width.

[0024] Support plate 8 provides support for the packaging bag. Support plate 8 is fixedly connected to the upper surface of base 1. Scale lines 14 are provided on the side surface of support plate 8 to facilitate measurement of the packaging bag size. A rotating plate 9 is rotatably connected inside support plate 8 to limit the position of the packaging bag for measurement. A lead screw motor 10 is fixedly connected inside support plate 8 to provide power for the rotation of lead screw 11. The output end of lead screw motor 10 is fixedly connected to lead screw 11, converting its rotational power into the displacement power of push plate 12. Push plate 12 is provided on the surface of lead screw 11 to push the packaging bag to move. A vertical plate 13 is fixedly connected to the upper surface of support plate 8 to provide support for the moving parts. A pressure plate 20 is fixedly connected inside push plate 12 and to the side surface of vertical plate 13 to press down the packaging bag and prevent it from being blown away. A roller motor 15 is fixedly connected inside the vertical plate 13, providing power for the rotation of the lower roller 16. The output end of the roller motor 15 is fixedly connected to the lower roller 16, which works with the upper roller 19 to clamp and move the packaging bag. The lower roller 16 is rotatably connected to the support plate 8, allowing the lower roller 16 to rotate normally. A lower gear 17 is fixedly connected to the side surface of the lower roller 16, driving the upper gear 18 that meshes with it to rotate. The lower gear 17 is meshed with the upper gear 18, driving the upper roller 19 to rotate. The upper roller 19 is fixedly connected to the side surface of the upper gear 18, working with the lower roller 16 to move the packaging bag. The upper roller 19 is rotatably connected to the vertical plate 13 and the upright plate 2, allowing the upper roller 19 to rotate normally. The upper roller 19 is located directly above the lower roller 16.

[0025] Working principle: During use, the operator can rotate the rotating plate 9 upwards, place the packaging bag on the upper surface of the support plate 8, with one side of the bag resting against the side surface of the rotating plate 9. Then, start the lead screw motor 10 to rotate the lead screw 11, causing it to move the push plate 12 on its surface to the other side of the packaging bag. At this time, the operator can measure the size of the packaging bag through the scale lines 14 set on the side surface of the support plate 8. Rotate the rotating plate 9 downwards so that it no longer obstructs the packaging bag, start the lead screw motor 10 to rotate the lead screw 11, causing the push plate 12 to push the packaging bag, thereby controlling the width of the folded edge of the packaging bag. Push the packaging bag out to a certain width, and place one end of the packaging bag between the upper roller 19 and the lower roller 16. Start the roller motor 15 to rotate the lower roller 16, which drives the lower gear 17 to rotate, which in turn drives the upper gear 18 that meshes with it to rotate. The upper gear 18 drives the upper roller 19 to rotate, thus enabling the roller to move the packaging bag. Start the fan motor 3 to rotate the fan 4 to blow air onto the packaging bag. Since the upper surface of the push plate 12 is equipped with a pressure plate 20, the packaging bag will not be blown away, and the part of the packaging bag protruding from the support plate 8 will be pressed down by the flowing air. Then start the pressure roller motor 6 to rotate the pressure roller 7 to fold the edge of the packaging bag, ensuring the folding accuracy of the packaging bag and preventing the packaging bag from being damaged. Subsequently, the folded part of the packaging bag will be pressed tightly by the pressure block 5, making the packaging bag folded more neatly.
