Description

Technical Field

[0001] This utility model belongs to the field of nonwoven fabric processing technology, specifically relating to an adjustable adhesive quantity control device for nonwoven fabric composites. Background Technology

[0002] Nonwoven fabrics have been widely used in recent years, including in medical supplies (disposable surgical gowns, masks, etc.), hygiene products (baby diapers, feminine hygiene products, etc.), and packaging materials. As the quality requirements for nonwoven fabric products continue to increase, their lamination processes are receiving more and more attention. In the nonwoven fabric lamination process, the use of adhesives is one of the key steps.

[0003] In the prior art, the piston stroke of traditional nonwoven fabric pump hoses is mostly fixed during extrusion. When extruding different nonwoven fabrics, the amount of extruded glue cannot be adjusted, which affects product quality. Therefore, this utility model proposes an adjustable glue amount control device for nonwoven fabric composites to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable adhesive amount control device for nonwoven fabric composites to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An adjustable adhesive control device for nonwoven fabric lamination includes a first fixed plate and a second fixed plate. A first fixed block is fixedly connected to each of the two end sidewalls of the first fixed plate, and a second fixed block is fixedly connected to each of the two end sidewalls of the second fixed plate. An extrusion tube is fixedly connected through the second fixed plate. A piston is slidably connected inside the extrusion tube. A U-shaped block is fixedly connected to the upper end of the piston. A second connecting block is rotatably connected inside the U-shaped block. A threaded rod is fixedly connected to the upper end of the second connecting block. A fixed tube is positioned above the extrusion tube. The threaded rod is slidably connected inside the fixed tube, and a nut is rotatably sleeved on the lower end of the fixed tube. The threaded rod passes through the nut and is threadedly connected to it.

[0007] Preferably, the first fixing block and the second fixing block on the same side are both fixedly connected by a fixing rod, and the two fixing rods are arranged symmetrically.

[0008] Preferably, the lower end of the first fixing plate is fixedly connected to two symmetrically arranged vertical plates, and a crossbar is rotatably connected to the side wall of the opposite end of each of the two vertical plates.

[0009] Preferably, a rotating plate is eccentrically fixed to one end of each of the two crossbars, and a connecting rod is fixedly connected between the two rotating plates.

[0010] Preferably, a first connecting block is rotatably sleeved on the connecting rod, and the lower end of the first connecting block is fixedly connected to the upper end of the fixed tube.

[0011] Preferably, a motor is fixedly connected to the side wall of one of the vertical plates, and the end of the output shaft of the motor is fixedly connected to the end of one of the horizontal bars.

[0012] Preferably, the lower end of the extrusion tube is provided with a one-way liquid outlet pipe, and the side wall of the extrusion tube is provided with a one-way liquid inlet pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By setting up a fixed tube, threaded rod, and nut, during extrusion, the output shaft of the drive motor rotates, causing the crossbar to rotate, which in turn causes the rotating plate to rotate around the crossbar as an axis. This, in turn, causes the connecting rod to rotate around the crossbar as an axis. Under the action of the connecting rod, the first connecting block moves up and down, which in turn causes the fixed tube to move up and down, and the threaded rod and piston to move back and forth, thus completing the pumping process. When it is necessary to pump liquid for different non-woven fabrics, the nut can be rotated to move the threaded rod that is threaded to it. Adjusting the distance that the threaded rod moves out of the fixed tube allows for adjustment of the piston stroke, which can control the amount of extrusion and facilitates the extrusion of different non-woven fabrics, greatly improving the practicality of the device.

Detailed Implementation

[0021] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Reference Figure 1-5 An adjustable adhesive control device for nonwoven fabric composites includes a first fixed plate 1 and a second fixed plate 6. First fixed blocks 2 are fixedly connected to both ends of the first fixed plate 1, and second fixed blocks 5 are fixedly connected to both ends of the second fixed plate 6. An extrusion tube 7 is fixedly connected through the second fixed plate 6. A piston 15 is slidably connected inside the extrusion tube 7. A U-shaped block 19 is fixedly connected to the upper end of the piston 15. A second connecting block 20 is rotatably connected inside the U-shaped block 19. A threaded rod 18 is fixedly connected to the upper end of the second connecting block 20. A fixed tube 16 is provided above the extrusion tube 7. The threaded rod 18 is slidably connected inside the fixed tube 16, and a nut 17 is rotatably sleeved at the lower end of the fixed tube 16. The threaded rod 18 passes through the nut 17 and is threadedly connected to it.

[0023] Furthermore, a fixing rod 3 is fixedly connected to both the first fixing block 2 and the second fixing block 5 on the same side. The two fixing rods 3 are arranged symmetrically. Two symmetrically arranged vertical plates 10 are fixedly connected to the lower end of the first fixing plate 1. A horizontal bar 11 is rotatably connected to the opposite side wall of the two vertical plates 10. A rotating plate 12 is eccentrically fixedly connected to the opposite end of the two horizontal bars 11. A connecting rod 13 is fixedly connected between the two rotating plates 12. A first connecting block 14 is rotatably sleeved on the connecting rod 13. The lower end of the first connecting block 14 is fixedly connected to the upper end of the fixing tube 16.

[0024] Furthermore, a motor 4 is fixedly connected to the side wall of one of the vertical plates 10, and the output shaft of the motor 4 is fixedly connected to the end of one of the horizontal bars 11. A one-way liquid outlet pipe 8 is provided at the lower end of the extrusion tube 7, and a one-way liquid inlet pipe 9 is provided on the side wall of the extrusion tube 7. A one-way liquid inlet valve is provided in the one-way liquid inlet pipe 9, which can only allow liquid to enter in one direction. A one-way liquid outlet valve is provided in the one-way liquid outlet pipe 8, which can only allow liquid to exit in one direction.

[0025] When using this invention, during the extrusion process, the glue storage tank is first connected to the one-way liquid inlet pipe 9. The output shaft of the drive motor 4 rotates, causing the crossbar 11 to rotate, which in turn causes the rotating plate 12 to rotate around the crossbar 11. This causes the connecting rod 13 to rotate around the crossbar 11. Under the action of the connecting rod 13, the first connecting block 14 moves up and down, which in turn causes the fixed pipe 16 to move up and down, and causes the threaded rod 18 and piston 15 to move back and forth, thus completing the pumping process. When pumping different nonwoven fabrics, the nut 17 can be rotated to move the threaded rod 18 that is threaded to it. The distance that the threaded rod 18 moves out of the fixed pipe 16 can be adjusted to adjust the stroke of the piston 15, thereby controlling the amount of glue extruded and facilitating the extrusion of different nonwoven fabrics.
