Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to a sheet packaging equipment. Background Art

[0002] After the sheet is produced, according to the process requirements, it is necessary to wrap the sheet between the upper packaging paper and the lower packaging paper through a laminating mechanism, and then the upper packaging paper and the lower packaging paper clamp the sheet and transport it to the next process. Currently, the sheet used for band-aids is composed of a bottom layer 1, an intermediate layer 2 and two release layers 3. The release layer 3 is prone to edge warping at the top of the sheet. When the sheet is transported between the upper packaging paper and the lower packaging paper through the air suction conveying mechanism, the warped release layer 3 is blocked by the upper packaging paper, causing relative movement between the sheet and the air suction conveyor belt, resulting in the skewing of the neatly placed sheet, so that the sheet cannot be neatly arranged between the upper packaging paper and the lower packaging paper. When the outer shape of the packaging paper is cut later, the sheet will be cut, resulting in unqualified products.

[0003] Therefore, a sheet packaging equipment that solves the above problems is needed. Summary of the Utility Model

[0004] The utility model provides a sheet packaging equipment. The upper packaging paper inclinedly arranged between the first smoothing and flattening roller and the first smoothing and flattening roller moves forward continuously, smoothing and gently pressing down the warped release layer on the sheet, and finally enabling the sheet to be neatly attached to the upper packaging paper and the lower packaging paper, avoiding the skewing of such easily warped-edge sheets during packaging.

[0005] The technical solution of the utility model is realized as follows:

[0007] An air suction conveying mechanism for conveying the sheet;

[0008] A first smoothing and flattening roller and a second smoothing and flattening roller for guiding the upper packaging paper. The first smoothing and flattening roller and the second smoothing and flattening roller are both rotatably installed on the frame. The axis of the first smoothing and flattening roller is higher than the axis of the second smoothing and flattening roller. The upper packaging paper forms a pressure-relieving angle for smoothing and pressing down the release layer between the first smoothing and flattening roller and the second smoothing and flattening roller;

[0009] A laminating mechanism for covering the upper packaging paper and the lower packaging paper on both sides of the sheet.

[0010] As a preferred technical solution, the laminating mechanism includes a laminating frame fixedly mounted on the frame, a laminating plate slidably mounted on the laminating frame along the forward direction of the sheet, an upper support frame for supporting the upper wrapping paper and a lower support frame for supporting the lower wrapping paper are mounted on the laminating plate, and a pressing plate for pressing the upper wrapping paper, the sheet and the lower wrapping paper together is fixedly mounted on the laminating plate.

[0011] As a preferred technical solution, the suction conveying mechanism includes a driving pulley and a driven pulley rotatably mounted on the frame, the driving pulley is transmission-connected with a first rotating driving device, a suction conveyor belt is wound between the driving pulley and the driven pulley, a plurality of suction holes are provided on the suction conveyor belt, the first smoothing and pressure-relief roller and the second smoothing and pressure-relief roller are both rotatably mounted above the suction conveyor belt, a suction groove is provided on the frame, the suction groove is provided between the driving pulley, the driven pulley and the suction conveyor belt, the suction groove is connected to an air pump, and the position of the suction groove corresponds to the position of the suction hole.

[0012] As a preferred technical solution, a heat pressing knife seat for heat pressing the upper wrapping paper and the lower wrapping paper is arranged downstream of the laminating mechanism, and the heat pressing knife seat is rotatably installed with a heat pressing bottom roller, a first heating roller and a second heating roller from bottom to top, and a wrapping paper preheating plate for preheating the hot melt adhesive on the upper wrapping paper and the lower wrapping paper is installed upstream of the heat pressing knife seat, a number of electric heating rods are fixedly installed on the wrapping paper preheating plate, and the wrapping paper preheating plate is installed on the heat pressing knife seat through a preheating plate mounting frame.

[0013] As a preferred technical solution, a cutting knife seat for cutting the outer contours of the upper packaging paper and the lower packaging paper is arranged downstream of the hot pressing knife seat, the cutting knife seat includes a cutting bottom roller, a cutting roller and a cutting rubber roller rotatably installed from bottom to top, and a traction assembly is installed upstream of the cutting knife seat, the traction assembly includes a traction mounting frame fixedly installed on the cutting knife seat, the traction mounting frame is rotatably installed with a first traction roller and a second traction roller from bottom to top, the first traction roller is transmission-connected to the second rotation driving device, and the first traction roller and the second traction roller are transmission-connected.

[0014] By adopting the above technical solution, the beneficial effects of the utility model are as follows:

[0015] Since the sheet packaging equipment includes the first smoothing and slow-pressing roller and the second smoothing and slow-pressing roller, during the use of the equipment, the sheet to be packaged is adsorbed on the suction conveyor belt at a certain distance, and moves downstream with the suction conveyor. When the sheet passes between the first smoothing and slow-pressing roller and the second smoothing and slow-pressing roller, since the moving direction of the upper packaging is the same as the direction in which the peeling layer needs to be smoothed, the upper packaging paper that continuously moves downstream has a smoothing effect on the peeling layer on the top of the sheet. At the same time, the bottom of the sheet is adsorbed on the suction conveyor belt by the negative pressure at the suction hole, and the peeling layer that is raised on the top of the sheet is The upper wrapping paper which is tilted is slowly pressed down and finally abuts on the upper wrapping paper. Then, under the traction of the upper wrapping paper, the bottom of the sheet is abutted on the lower wrapping paper, thus completing the packaging of the sheet. In the utility model, the upper wrapping paper which is tilted between the first smoothing and pressing roller and the second smoothing and pressing roller continues to move forward, smoothes and slowly presses down the raised peeling layer on the sheet, and finally makes the sheet neatly fit with the upper wrapping paper and the lower wrapping paper, thus avoiding the occurrence of skewness during packaging of such sheets which are prone to warping, and further avoiding the occurrence of unqualified products due to the skewness of the sheets.

[0016] Since the sheet packaging equipment includes a laminating mechanism, after the top of the sheet is laminarized with the upper packaging paper and the bottom is laminarized with the lower packaging paper, the sheet passes through the pressing plate and the laminating plate under the synchronous traction of the two packaging papers. The pressing plate further presses and laminates the upper packaging paper, the sheet and the lower packaging paper. The distance between the laminating plate and the suction conveyor is achieved by rotating the adjusting shaft and adjusting the meshing of the gear and the rack, thereby adapting to the connection of sheets of different sizes.

[0017] Since the sheet packaging equipment includes a hot pressing knife seat, after the sheet is wrapped by the upper packaging paper and the lower packaging paper, it enters the hot pressing knife seat, and under the action of the packaging paper preheating plate, the hot melt adhesive on the upper packaging paper and the lower packaging paper is preheated, thereby avoiding the occurrence of incomplete melting of the hot melt adhesive on the packaging paper. Then the sheet passes between the first heating roller and the second heating roller, and with the coordinated cooperation of the first heating roller and the second heating roller, the positions on the upper packaging paper and the lower packaging paper that need to be hot pressed are heated and pressed, thereby achieving the sealing of the upper packaging paper and the lower packaging paper on the sheet.

[0018] Since the sheet packaging equipment includes a cutting knife seat, after the upper packaging paper and the lower packaging paper are hot-pressed, they are cut through the outer contour of the packaging paper on the cutting knife seat. A traction assembly is installed upstream of the cutting knife seat. Compared with the traditional traction mechanism, the utility model installs the first traction roller and the second traction roller on the cutting knife seat through a traction mounting frame, so that the installation position of the first traction roller and the second traction roller is closer to the cutting roller and the cutting rubber roller, which reduces the volume of the equipment and makes the packaging paper more stable when cutting.
