Abstract
Description
Technical Field
[0001] The invention relates to the field of non-woven fabric processing, and in particular to a glue spraying device which is convenient for uniformly spraying glue on non-woven fabrics of different widths. Background Art
[0002] When processing existing non-woven fabrics, two layers of non-woven fabrics need to be overlapped, or non-woven fabrics need to be radially overlapped with other materials. When overlapping, the non-woven fabrics need to be sprayed with glue, and then the non-woven fabrics need to be bonded with another layer of non-woven fabrics or other materials.
[0003] When spraying glue on non-woven fabrics, glue is sprayed on the non-woven fabrics through several rows of glue spray heads arranged in a line. Each row of glue spray heads is provided with the same number of glue spray heads, and the glue spray heads in the same row spray glue or close synchronously. By arranging several rows of glue spray heads along the width direction of the non-woven fabric, glue is evenly sprayed on the surface of the non-woven fabric after it moves, thereby ensuring bonding with another layer of non-woven fabric or other materials in the subsequent process.
[0004] When spraying glue on non-woven fabrics of different widths, the glue is sprayed by opening the corresponding rows of glue spray heads. However, since the width of non-woven fabrics does not vary between specific sizes, when several rows of glue spray heads are opened for spraying, some of the glue spray heads in the edge row are prone to spray outside the non-woven fabric; or the edge of the non-woven fabric is not sprayed. It is necessary to block the glue spray heads at the edge to avoid spraying outside the non-woven fabric. However, when some glue spray heads are blocked, the glue spraying amount of the glue spray heads in the same row will increase significantly, resulting in uneven glue spraying. At the same time, the glue spray heads are prone to malfunction and damage.
[0005] Therefore, it is necessary for us to improve such a structure to overcome the above-mentioned defects. Summary of the invention
[0006] The object of the present invention is to provide a glue spraying device which is convenient for uniformly spraying glue on non-woven fabrics of different widths.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with diagrams and specific embodiments.
[0022] like Figures 1 to 3 As shown, the present invention proposes a glue spraying device for evenly spraying glue on non-woven fabrics of different widths, including a frame 1, wherein the frame 1 is provided with a conveying roller 2 for conveying the non-woven fabric, a glue spraying mechanism for spraying glue on the non-woven fabric, and a positioning plate 3 for aligning the side edge position of one side of the non-woven fabric.
[0023] The glue spraying mechanism includes a glue spraying main frame 4 installed just above the non-woven fabric, a plurality of glue conveying frames 5 installed on the glue spraying main frame 4 and arranged in a straight line, and a rotating assembly installed between the glue spraying main frame 4 and the frame 1 and controlling the rotation of the glue spraying main frame 4. Each of the glue conveying frames 5 is connected to a plurality of glue spraying heads 6 for spraying glue on the non-woven fabric, and two adjacent glue conveying frames 5 are closely arranged, and the glue spraying heads 6 connected to the same glue conveying frame 5 are defined as a row, that is, a plurality of rows of glue spraying heads 6 are closely arranged in a straight line through a plurality of glue conveying frames 5. In addition, the glue spraying main frame 4 is rotatably connected to the frame 1, and the rotation axis of the glue spraying main frame 4 is vertically arranged, and the rotation axis of the glue spraying main frame 4 and the positioning plate 3 are located in the same vertical plane position, and a plurality of glue spraying heads 6 are arranged from the rotation position of the glue spraying main frame 4 toward the other side of the non-woven fabric. That is, a plurality of glue spray heads 6 are arranged toward the other side with the side of the non-woven fabric close to the positioning plate 3 as the origin, and when the width of the glue spraying needs to be adjusted, the glue spraying main frame 4 is driven to deflect by a certain angle through the rotating component, so that the length direction of the glue spraying main frame 4 is inclined relative to the width direction of the non-woven fabric, thereby achieving the adjustment of the glue spraying width range; thereby achieving the goal of adapting to the glue spraying of non-woven fabrics of different widths, avoiding the problem that the edge of the non-woven fabric cannot be sprayed with glue or the glue spraying exceeds the edge of the non-woven fabric.
[0024] The rotating assembly includes a rotating shaft 7 fixedly connected to the upper end surface of the glue spraying main frame 4, a driven gear 8 arranged on the rotating shaft 7, a driving motor 9 arranged on the frame 1 and driving the rotating shaft 7 to rotate, and a driving gear 10 arranged on the output shaft of the driving motor 9. The driving gear 10 meshes with the driven gear 8 and drives the driven gear 8 to rotate. The rotating shaft 7 is vertically arranged, and the rotating shaft 7 and the positioning plate 3 are located in the same vertical plane position. When it is necessary to drive the glue spraying main frame 4 to deflect and adjust the glue spraying width, the rotating shaft 7 is driven to rotate by the driving motor 9, the driving gear, and the driven gear 8, so that the glue spraying main frame 4 deflects, thereby adjusting the glue spraying width.
[0025] In order to prevent the glue spraying main frame 4 from being relatively movable after the glue spraying main frame 4 is deflected, a positioning component is provided between the rotating shaft 7 and the frame 1 to position the glue spraying main frame 4 after the rotating angle. The positioning component includes a first end face toothed disc 11 provided on the upper end face of the rotating shaft 7, a slider 12 which is slidably connected to the frame 1 in the vertical direction and is located directly above the rotating shaft 7, a second end face toothed disc 13 which is provided on the lower end face of the slider 12 and can mesh with the first end face toothed disc 11, and a driving structure 14 which is provided on the frame 1 and drives the slider 12 to move up and down. The driving structure 14 can be an electric cylinder or a pneumatic cylinder, etc. In addition, a guide rail 17 is provided between the frame 1 and the slider 12. The guide rail 17 is provided vertically, and the slider 12 is made to slide downward in the vertical direction through the guide rail 17. When the glue spraying main frame 4 is driven to deflect a certain angle by the driving motor 9, the driving structure 14 drives the slider 12 to move downward, so that the second end face toothed disc 13 engages with the first end face toothed disc 11, thereby limiting the rotation of the rotating shaft 7, effectively fixing the relative position of the glue spraying main frame 4, and improving the accuracy of the glue spraying width.
[0026] In this embodiment, the glue spraying main frame 4 is connected with a delivery pipe 15 for delivering glue to the glue delivery frame 5. The delivery pipe 15 is located at one end of the glue spraying main frame 4 close to the rotating assembly, and the delivery pipe 15 is provided with a control valve 16 for controlling the flow of glue, and each of the glue delivery frames 5 is provided with a switch valve for controlling the opening and closing of the glue spraying head 6 connected to the corresponding glue delivery frame 5. That is, the delivery pipe 15 is connected with multiple glue delivery frames 5, and the glue in the delivery pipe 15 is discharged from the glue spraying head 6 through the internal pipe of the glue delivery frame 5, and the opening and closing of the glue spraying head 6 connected to the glue delivery frame is controlled by the switch valve of the glue delivery frame 5. In order to adapt to the glue spraying amount of non-woven fabrics of different widths, the glue flow is adjusted by the control valve 16 to ensure that the glue spraying thickness is appropriate while the non-woven fabrics are uniformly sprayed, so as to avoid excessive or insufficient glue attached to the non-woven fabrics.
