Description

Technical Field

[0001] The utility model relates to the field of sprayed cotton, in particular to a nozzle reciprocating movement driving mechanism for the production of sprayed cotton. Background Technique

[0002] Sprayed cotton, also known as sprayed pulp cotton, is a non-woven fabric mainly made of natural cotton fibers, artificial fibers or synthetic fibers through processes such as loosening, carding, spraying glue, baking and curing. During the production of sprayed cotton, adhesives need to be sprayed on both sides of the fluffy fiber layer, which requires the use of a nozzle reciprocating movement driving mechanism. Through the pressure during reciprocating spraying and the suction during lower vacuum liquid suction, the adhesive penetrates into the interior of the fiber layer. After drying and curing, the intersection points between the fibers are bonded, while the fibers that are not bonded to each other still maintain a relatively large degree of freedom. At the same time, there are many air-containing voids retained in the three-dimensional network structure, so it has the heat preservation effect of porosity and high fluffiness.

[0003] During the use of the existing nozzle reciprocating movement driving mechanism for the production of sprayed cotton, the motor drives the lead screw to rotate forward and backward, so that the nozzle sprays the adhesive back and forth on the sprayed cotton below. However, due to the different widths of the sprayed cotton, the nozzle reciprocating movement driving mechanism that cannot adjust the reciprocating running distance often causes waste of the sprayed adhesive, thus affecting the normal production work of the sprayed cotton.

[0004] Therefore, it is very necessary to invent a nozzle reciprocating movement driving mechanism for the production of sprayed cotton to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a nozzle reciprocating movement driving mechanism for the production of sprayed cotton. By means of a reciprocating drive body, a threaded lead screw, a reciprocating nut sleeve, a first bevel gear, a second bevel gear, a sliding rod and a reciprocating distance sleeve, the position of the reciprocating distance sleeve on the sliding rod is adjusted according to the width of the sprayed cotton that needs to be sprayed with adhesive currently, reducing the situation of waste of sprayed adhesive caused by the nozzle exceeding the range. At the same time, it can also leave a buffer space for the servo motor to reverse, drive the reciprocating nut sleeve to move reciprocally, and reduce the loss and burden on the sliding rod and the servo motor caused by hard reciprocating rotation, so as to solve the problem that during the use of the existing nozzle reciprocating movement driving mechanism for the production of sprayed cotton, the motor drives the lead screw to rotate forward and backward, so that the nozzle sprays the adhesive back and forth on the sprayed cotton below. However, due to the different widths of the sprayed cotton, the nozzle reciprocating movement driving mechanism that cannot adjust the reciprocating running distance often causes waste of the sprayed adhesive, thus affecting the normal production work of the sprayed cotton.

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further introduced in detail below with reference to the accompanying drawings.

[0026] The present invention provides a nozzle reciprocating movement driving mechanism for the production of glue-sprayed cotton as shown in Figures 1-5 Figure, including a reciprocating drive body 1 for carrying and installing components for the reciprocating movement of the nozzle;

[0027] A fixed frame 6 is arranged inside the reciprocating drive body 1 for connecting the threaded lead screw 7, and a reciprocating nut 8 is movably connected to the outside of the threaded lead screw 7. One end of the threaded lead screw 7 is fixedly installed with a first bevel gear 9, and a second bevel gear 10 is movably connected to one side of the first bevel gear 9. A servo motor 11 is fixedly installed outside the second bevel gear 10;

[0028] A sliding rod 12 is arranged on one side of the threaded lead screw 7 for restricting the reciprocating movement spacing of the nozzle, and a positioning bolt 13 penetrates through the outside of the sliding rod 12. One end of the positioning bolt 13 is movably connected to a reciprocating spacing sleeve 14, and a torsion spring 15 is arranged on one side of the reciprocating spacing sleeve 14, and a contact sleeve 16 is arranged on the other side of the torsion spring 15. After the reciprocating nut 8 is affected by the rotation of the threaded lead screw 7 and moves left and right on the sliding rod 12, the moving distance of the reciprocating nut 8 can be restricted, thereby reducing the situation of spraying waste of the adhesive caused by the nozzle exceeding the range.

[0029] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a side mounting plate 2 is fixedly installed outside the reciprocating drive body 1. One side of the side mounting plate 2 is penetrated by a fixing bolt 3, and a tightening gasket 4 is arranged outside the fixing bolt 3. An upper cover plate 5 is arranged above the reciprocating drive body 1. The side mounting plate 2 facilitates the cooperative installation of the device with the machinery used in the production of sprayed cotton, thereby completing the spraying work of the sprayed cotton adhesive. The reciprocating wire sleeve 8 is movably connected to the threaded lead screw 7, and the first bevel gear 9 is meshed with the second bevel gear 10. The structures of the first bevel gear 9 and the second bevel gear 10 are simple, driving the reciprocating wire sleeve 8 to reciprocate on the threaded lead screw 7. The abutting sleeve 16 is movably connected to the torsion spring 15, and the reciprocating spacing sleeve 14 is threadedly connected to the sliding rod 12. When the reciprocating wire sleeve 8 reaches one end of the sliding rod 12, the abutting sleeve 16 will be squeezed to drive the torsion spring 15 to expand and contract and buffer towards the fixed reciprocating spacing sleeve 14, so that the servo motor 11 can leave a buffer space to reverse, driving the reciprocating wire sleeve 8 to reciprocate, reducing the loss and burden brought to the sliding rod 12 and the servo motor 11 by the hard rotation of the reciprocation.

[0030] As Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, a manual telescopic rod 17 is fixedly installed at the bottom of the reciprocating wire sleeve 8, and a sprayed cotton nozzle holder 18 is fixedly installed at the bottom of the manual telescopic rod 17. A main spray body 19 is arranged inside the sprayed cotton nozzle holder 18. The manual telescopic rod 17 can adjust the distance between the spray nozzle 23 and the sprayed cotton according to the height of the current sprayed cotton production. A drive motor 20 is arranged outside the main spray body 19. A forward gear 21 is fixedly installed at the output end of the drive motor 20. A forward tooth disc 22 is movably connected to one side of the forward gear 21. A spray nozzle 23 is arranged inside the forward tooth disc 22. By driving the forward gear 21 to rotate by the drive motor 20, the forward tooth disc 22 meshed with the forward gear 21 drives the spray nozzle 23 to adjust the angle below the main spray body 19. In this way, on the basis of the original reciprocating operation for spraying the adhesive on the sprayed cotton, the current spraying range is expanded, making the adhesive spray more evenly on the sprayed cotton.

[0031] The working principle of the utility model is as follows: firstly, the external power supply is turned on, and the device is installed in coordination with the machine for producing the spray-bonded cotton through the side mounting plate 2, the fixing bolt 3 and the tightening gasket 4, so as to facilitate the spraying of the adhesive of the spray-bonded cotton. Then, after the device is installed, the position of the reciprocating spacing sleeve 14 on the sliding rod 12 can be adjusted by the positioning bolt 13 according to the width of the spray-bonded cotton that needs to be sprayed with adhesive at present before starting. In this way, when the reciprocating wire sleeve 8 is affected by the rotation of the threaded screw 7 and moves left and right on the sliding rod 12, the moving distance of the reciprocating wire sleeve 8 can be limited, thereby reducing the nozzle from exceeding The scope causes waste of spraying of adhesive, then twist the external knob of the manual telescopic rod 17 to adjust the length of the manual telescopic rod 17, so that the glue nozzle 23 is closer to the glue cotton, and then connect the external adhesive pipeline and the main spray body 19, and then start the spraying of adhesive in the production of glue cotton. First, turn on the switch of the servo motor 11, and the servo motor 11 drives the first bevel gear 9 and the second bevel gear 10 to rotate. Affected by the rotation of the first bevel gear 9 and the second bevel gear 10, the reciprocating wire sleeve 8 reciprocates on the threaded screw 7, and then the reciprocating wire sleeve 8 also synchronously drives The glue spray nozzle 23 moves left and right to start spraying the adhesive. At this time, when the reciprocating wire sleeve 8 reaches one end of the sliding rod 12, the contact sleeve 16 will be squeezed to drive the torsion spring 15 to retract and buffer the fixed reciprocating spacing sleeve 14, so that the servo motor 11 leaves a buffer space for reversal, driving the reciprocating wire sleeve 8 to reciprocate, reducing the loss and burden of the hard reciprocating movement on the sliding rod 12 and the servo motor 11. Then, during the spraying process, the switch of the drive motor 20 can be turned on to allow the drive motor 20 to drive the forward gear 21 to rotate, and the forward gear disc 22 meshing with the forward gear 21 is engaged with the forward gear 21. This drives the glue spray nozzle 23 to adjust its angle below the main spray body 19, so that when the original reciprocating operation is used to spray adhesive on the glue spray cotton, the current spraying range can be expanded, and the adhesive can be sprayed more evenly on the glue spray cotton, thereby ensuring the production efficiency of the glue spray cotton. Finally, after completing the installation and use of the nozzle reciprocating motion drive mechanism for the production of all glue spray cotton according to the above operations, turn off the switch of the servo motor 11, turn off the switch of the drive motor 20, and cut off the external power supply if it is not used for a long time. In this way, the use process of the nozzle reciprocating motion drive mechanism for the production of glue spray cotton is completed.

[0032] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
