For example, in the patent document with application number 202321599835.4, a modified polypropylene plastic woven bag hemming device is disclosed, and a device for pressing the edge position of the woven bag is specifically disclosed, thereby realizing the hemming of the woven bag and avoiding wrinkles at the sealing position of the woven bag.

[0003] The woven bag needs to be sealed after folding, so the edge position of the woven bag needs to be ensured after folding to prevent it from rebounding. In the above technical solution, the heat is transferred to the folded edge position of the woven bag by using the cooperation of the heat insulation plate and the heat conductive sheet to achieve the effect of heating and shaping. However, this method will cause the folded edge position and the woven bag cloth to form a certain angle. When the woven bag is transferred, it is very easy for the folded edge position to contact some equipment in the frame, causing the folded edge position to be easily collided and wrinkled, thereby affecting the adhesion of the folded edge position and the edge position of the woven bag.

DETAILED DESCRIPTION

[0017] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0018] See also Figure 1-2 As shown, the plastic woven bag folding device includes a woven bag 1 and an edge strip 2. The edge strip 2 is folded from the woven bag 1 by a bending mechanism in the folding device. Then, when the position of the edge strip 2 is limited, that is, in order to avoid the rebound of the edge strip 2, the present application adopts the method of using glue to perform preliminary adhesion before pressing down to form wrinkles to avoid the rebound of the edge strip 2. That is, in the present application, the glue can be distributed at intervals to only avoid the rebound of the edge strip 2.

[0019] Specifically, when the edge band 2 is folded, the edge of the woven bag 1 is sprayed with glue, and then the edge band 2 is pressed down and attached to the woven bag 1, and the glue is used to achieve adhesion between the edge band 2 and the woven bag 1, thereby avoiding the rebound of the edge band 2.

[0020] The glue is sprayed from the glue nozzle 13, wherein the spraying angle of the glue nozzle 13 is inclined, so that the glue nozzle 13 can be sprayed on the woven bag 1 at an angle, and then the edge banding strip 2 is moved longitudinally to attach the edge banding strip 2 to the glue portion of the glue nozzle 13 to limit the position of the edge banding strip 2.

[0021] When pressing the edge banding strip 2 downward, a pressing plate 3 is used in the present application, wherein the pressing plate 3 is movable longitudinally, and the pressing plate 3 moves longitudinally to press on the edge banding strip 2, forming wrinkles on the edge positions of the edge banding strip 2 and the woven bag 1, and preliminarily reducing the rebound of the edge banding strip 2. At the same time, since the edge banding strip 2 is pressed on the sprayed glue, the rebound of the edge banding strip 2 can be avoided, so as to facilitate further edge sealing treatment of the edge banding strip 2.

[0022] Since the pressing plate 3 is movable longitudinally, the pressing plate 3 is installed at the end of the first sliding rod 4, wherein the first sliding rod 4 is slidably connected to the first sliding sleeve 5 through a rebound assembly, wherein the first sliding rod 4 extends out of the first sliding sleeve 5, and the first sliding rod 4 is pressed down by a pressing mechanism.

[0023] The rebound component is used to provide a longitudinal upward thrust for the pressure plate 3, and under the action of the pressing mechanism, the first slide bar 4 is pressed downward, so that the first slide bar 4 overcomes the rebound force of the rebound component, so that the pressure plate 3 is pressed on the edge banding strip 2, and the edge banding strip 2 is used to move to the woven bag 1 to form wrinkles to prevent it from rebounding.

[0024] The rebound component includes an internal spring 16, and an internal slide groove 14 is opened inside the first sliding sleeve 5, wherein the internal slide groove 14 and the internal slide plate 15 are slidingly connected, wherein the internal slide plate 15 and the first sliding rod 4 are fixedly connected, and an internal spring 16 is fixed between the internal slide plate 15 and the first sliding sleeve 5.

[0025] By utilizing the rebound force of the internal spring 16, the internal slide plate 15 is always in an upward elastic force. Under the action of the downward pressing mechanism, the first slide bar 4 is pressed downward, so that the internal slide plate 15 slides inside the internal slide groove 14, so that the internal spring 16 is squeezed, thereby being able to control the downward pressing effect of the pressure plate 3.

[0026] The pressing mechanism includes a rotating platform 8, wherein the rotating platform 8 is mounted on a hinged base 6 by rotation, wherein a cam 7 is arranged above the rotating platform 8, wherein the cam 7 is tightly attached to the rotating platform 8, wherein the first slide bar 4 and the second slide bar 11 are respectively in contact with the rotating platform 8, and under the action of the rebound components of the first slide bar 4 and the second slide bar 11, the rotating platform 8 is in a balanced position, and when the cam 7 rotates, a downward pressure is applied to one direction of the rotating platform 8, so that the pressure plate 3 moves longitudinally, thereby realizing the pressing effect on the edge banding strip 2, but under the action of the rebound force of the second slide bar 11, the glue nozzle 13 moves upward under the action of the connecting rod 12, so that it is away from the edge banding strip 2, so as to facilitate the preliminary edge banding treatment of the edge banding strip 2.

[0027] Therefore, the cam 7 in the present application is located on the side of the rotating platform 8 close to the first slide bar 4, and the cam 7 is driven by a driving motor, so that the driving motor can drive the cam 7 to rotate, thereby achieving a downward pressure on the rotating platform 8.

[0028] In the present application, the glue nozzle 13 is fixedly mounted on the connecting rod 12, wherein the connecting rod 12 is fixedly mounted on the second sliding rod 11, wherein the second sliding rod 11 and the second sliding sleeve 10 are connected through a rebound assembly, wherein the second sliding rod 11 extends out of the second sliding sleeve 10, and the second sliding rod 11 contacts the rotating platform 8.

[0029] In the present application, the function of the rebound component is utilized so that when the rotating platform 8 rotates, the second slide rod 11 can move upward, so that the glue nozzle 13 is away from the edge banding strip 2 when pressed down and fixed, thereby realizing the formation of wrinkles on the edge banding strip 2 and the adhesion effect between the edge banding strip 2 and the woven bag 1.

[0030] The first sliding sleeve 5 and the second sliding sleeve 10 are installed on the mounting base 9, the crane mounting base 9 and the hinged base 6 are fixedly connected, and the mounting base 9 is fixedly installed on the frame, so as to achieve the position limitation of the first sliding sleeve 5 and the second sliding sleeve 10.

[0031] When the utility model is in use, the edge strip 2 is first folded to the top of the woven bag 1, and then the glue is sprayed on the woven bag 1 by the glue nozzle 13. At this time, the glue is located directly below the edge strip 2. Then, the driving motor drives the cam 7 to make one side of the rotating platform 8 sink, that is, the rotating platform 8 is used to push the first slide bar 4. At this time, the internal slide plate 15 moves downward inside the first sliding sleeve 5, so that the internal spring 16 bears the downward pressure, and the pressing plate 3 presses the edge strip 2 downward, so that the edge strip 2 is pressed at the gluing position of the woven bag 1, so as to realize the formation of wrinkles in the edge strip 2, and connect the edge strip 2 and the woven bag 1 to form a position limitation; at the same time, under the action of the rebound mechanism, the second slide bar 11 moves longitudinally, so that the glue nozzle 13 is away from the woven bag 1, so as to avoid the glue nozzle 13 interfering with the use of the pressing plate 3.

[0032] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
