Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric coating technology, specifically a nonwoven fabric coating device. Background Technology

[0002] Non-woven fabric is formed by the directional or random interlacing of fiber filaments without knitting. It is then fixed by mechanical equipment to prevent it from unraveling. Because the surface of non-woven fabric is rough, printing directly on it will result in an uneven surface and poor printing effect. Therefore, before printing, the surface of non-woven fabric needs to be coated to make the surface flat and better for printing. Thus, a coating device is required when coating non-woven fabric.

[0003] Currently, existing laminating equipment typically requires spraying adhesive onto the nonwoven fabric and then pressing the nonwoven fabric and film together using two vertically positioned hot rollers to form a single unit. However, the current adhesive spraying process usually involves the reciprocating movement of a spray gun to apply the adhesive to the nonwoven fabric. To ensure even application of the adhesive, the nonwoven fabric and film need to stop moving during the spraying process, which wastes a significant amount of time and reduces the efficiency of nonwoven fabric lamination. Utility Model Content

[0004] The purpose of this invention is to provide a nonwoven fabric coating device to solve the problems mentioned in the background art.

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

[0006] A nonwoven fabric coating device, comprising:

[0007] An operating table, wherein two symmetrical auxiliary rollers are provided at one end of the top surface of the operating table, and two vertically symmetrical hot rolling rollers are provided on the top surface of the operating table.

[0008] A glue spraying mechanism is set above the operating table and can spray glue onto non-woven fabric. The glue spraying mechanism includes a circular tube arranged along the width of the operating table. Multiple nozzles that communicate with the inside of the circular tube are fixedly connected at equal intervals to the bottom of the outer wall of the circular tube. A glue pressing component for pressing glue into the circular tube is provided on the bottom surface of the operating table.

[0009] The cooling mechanism, located above the operating table and on one side of the two hot rollers, enables the adhesive to cure quickly.

[0010] Furthermore, both ends of the circular tube are fixedly connected to a connector, the pressing component includes a pump body fixedly connected to the bottom surface of the operating table, the output end of the pump body is fixedly connected to a three-way pipe, and both ends of the three-way pipe are fixedly connected to a connecting pipe that is inserted into a connector at the corresponding position.

[0011] Furthermore, the top surface of the operating table is fixedly connected to two fixed plates on both sides and between the two auxiliary rollers, which are fixedly connected to the circular tube. The bottom surface of the operating table is fixedly connected to a storage box, and the input end of the pump body passes through the storage box and extends into the interior of the storage box.

[0012] Furthermore, the cooling mechanism includes a second circular tube and a third circular tube. The bottom of the outer wall of the second circular tube is fixedly connected with a plurality of nozzles second that communicate with the interior of the second circular tube at equal intervals. The bottom of the outer wall of the third circular tube is fixedly connected with a plurality of nozzles third that communicate with the interior of the third circular tube at equal intervals.

[0013] Furthermore, one end of the second round tube is fixedly connected to the second connector, and the end of the second round tube away from the second connector is fixedly connected to a plug.

[0014] Furthermore, both ends of the circular tube three are fixedly connected to connector three, the bottom surface of the operating table is fixedly connected to an air pump, the output end of the air pump is fixedly connected to a three-way pipe two, and both ends of the three-way pipe two are fixedly connected to connecting pipe two that are inserted into connector three at the corresponding positions.

[0015] Furthermore, all three circular tubes are rigid tube structures, and both sides of the top surface of the operating table are fixedly connected with support plates that penetrate and are fixed to the two circular tubes.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. By setting multiple nozzles on the round tube, adhesive can be sprayed along the width of the nonwoven fabric. Therefore, the nozzles do not need to move or the nonwoven fabric is not stopped during the adhesive spraying process, which can save a lot of time and improve the efficiency of nonwoven fabric coating. Moreover, the nozzles can be blocked by using a cap, and the appropriate number of nozzles can be selected according to the width of the nonwoven fabric.

[0018] 2. Water is pumped into the second round tube by a water pump and sprayed onto the non-woven fabric after lamination through multiple nozzles. The water absorbs the heat from the adhesive. Then, driven by an air pump, high-pressure gas is injected into the third round tube and sprayed out from multiple nozzles. The sprayed high-pressure gas dries the water adhering to the non-woven fabric and blows away the heat from the non-woven fabric. Thus, the non-woven fabric behind the lamination can be cooled down quickly through double-layer cooling. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 - Figure 4 In this embodiment of the present invention, a nonwoven fabric coating device includes an operating table 1. Two symmetrical auxiliary rollers are provided at one end of the top surface of the operating table 1. Two vertically symmetrical hot rollers are provided on the top surface of the operating table 1. A glue spraying mechanism 2 for spraying glue onto the nonwoven fabric is provided above the operating table 1. The glue spraying mechanism 2 includes a circular tube 21 arranged along the width direction of the operating table 1. Multiple nozzles 22 that communicate with the interior of the circular tube 21 are fixedly connected at equal intervals to the bottom end of the outer wall of the circular tube 21. A glue pressing component for pressing glue into the circular tube 21 is provided on the bottom surface of the operating table 1. A cooling mechanism 3 for quickly curing the glue is provided above the operating table 1 and on one side of the two hot rollers.

[0026] Specifically, firstly, the nonwoven fabric roll and the film roll are placed on the support frame at one end of the operating table 1. Then, one end of both the nonwoven fabric and the film are passed between two hot rollers. Adhesive is then injected into the round tube 21 through the pressing component and sprayed onto the nonwoven fabric through multiple nozzles 22. As the two hot rollers rotate and generate heat, they can transport the nonwoven fabric and film. During transport, the two hot rollers press the film onto the nonwoven fabric and adhere it with adhesive. Because the adhesive is at a high temperature under the action of the hot rollers, in order to... In the subsequent process of winding up the coated nonwoven fabric, the adhesive in the nonwoven fabric can be rapidly cooled by the cooling mechanism 3. This device has multiple nozzles 22 set on the round tube 21, which can spray adhesive along the width of the nonwoven fabric. Therefore, the nozzles 22 do not need to move during the adhesive spraying process, nor does the nonwoven fabric feeding need to be stopped, which can save a lot of time and improve the efficiency of nonwoven fabric coating. Moreover, the nozzles 22 can be blocked by using a cap, and the appropriate number of nozzles 22 can be selected according to the width of the nonwoven fabric.

[0027] Example 1

[0028] like Figure 3 As shown, in this embodiment, both ends of the circular tube 21 are fixedly connected to connectors 23. The pressing component includes a pump body 25 fixedly connected to the bottom surface of the operating table 1. The output end of the pump body 25 is fixedly connected to a three-way pipe 26. Both ends of the three-way pipe 26 are fixedly connected to connecting pipes 24 that are inserted into the connectors 23 at the corresponding positions. Both sides of the top surface of the operating table 1 and located between the two auxiliary rollers are fixedly connected to fixing plates 11 that penetrate and are fixed to the circular tube 21. The bottom surface of the operating table 1 is fixedly connected to a storage box 27. The input end of the pump body 25 penetrates the storage box 27 and extends into the interior of the storage box 27.

[0029] In this embodiment, the operation of the pump body 25 can draw the glue in the storage tank 27 into the round tube 21, so that each nozzle 22 can spray glue simultaneously and evenly (a one-way valve can be installed at each nozzle 22, and when the pressure in the round tube 21 reaches a certain level, the one-way valve will be opened, and the glue will be sprayed out).

[0030] Design Example 2

[0031] like Figure 4As shown, in this embodiment, the cooling mechanism 3 includes a second circular tube 31 and a third circular tube 33. The bottom of the outer wall of the second circular tube 31 is fixedly connected with a plurality of nozzles 32 that communicate with the interior of the second circular tube 31 at equal intervals. The bottom of the outer wall of the third circular tube 33 is fixedly connected with a plurality of nozzles 34 that communicate with the interior of the third circular tube 33 at equal intervals. One end of the second circular tube 31 is fixedly connected to a connector 35. The end of the second circular tube 31 away from the connector 35 is fixedly connected to a plug. Both ends of the third circular tube 33 are fixedly connected to connectors 36. The bottom surface of the operating table 1 is fixedly connected to an air pump 38. The output end of the air pump 38 is fixedly connected to a three-way pipe 37. Both ends of the three-way pipe 37 are fixedly connected to connecting pipes 2 that are inserted into the connectors 36 at the corresponding positions. The first circular tube 21, the second circular tube 31, and the third circular tube 33 are all rigid pipe structures. Both sides of the top surface of the operating table 1 are fixedly connected to support plates 12 that penetrate and are fixed to the second circular tube 31 and the third circular tube 33.

[0032] In this embodiment, water is pumped into the circular tube 31 and sprayed onto the coated nonwoven fabric through multiple nozzles 32 (the power of the water pump can be relatively low so that the water sprayed from the nozzles 32 is similar to a light drizzle). The water absorbs heat from the adhesive. Then, driven by the air pump 38, high-pressure gas is injected into the circular tube 33 and sprayed out from multiple nozzles 34. The sprayed high-pressure gas dries the water adhering to the nonwoven fabric and blows away the heat from the nonwoven fabric. Thus, the nonwoven fabric behind the membrane can be rapidly cooled through double-layer cooling.
