Description

Technical Field

[0001] This application relates to the field of net laying machines, and in particular to a net laying machine. Background Technology

[0002] Nonwoven fabric is a type of fabric that does not require spinning or weaving. It is made by arranging short textile fibers or filaments in a directional or random manner to form a web structure, which is then reinforced by methods such as friction and cohesion.

[0003] Currently, in the web-forming process of nonwoven fabrics, web-laying equipment is generally used to form the fabric into a web structure. Web-laying equipment typically includes a feeding mechanism, a web-laying mechanism, and a web curtain. The feeding mechanism, web-laying mechanism, and web curtain are all mounted on the frame, with the web-laying mechanism located below the feeding mechanism and the web curtain located below the web-laying mechanism. The feeding mechanism is used to convey the web to the web-laying mechanism, and the web-laying mechanism is used to convey the web conveyed by the feeding mechanism to the web curtain, so that the web forms a layered structure. Then, the web is transported to the next process for setting.

[0004] Traditionally, adhesive is sprayed onto the surface of the fiber web after it has been stacked into layers, thus adding binders or other fiber powders with different melting points to improve the web's physical or chemical properties. However, with this method, uneven penetration of the adhesive into the interlayer spaces of the web can easily occur. Summary of the Invention

[0005] In order to improve the uniformity of adhesive spraying on the fiber web, this application provides a web laying machine.

[0006] This application provides a net laying machine, which adopts the following technical solution:

[0007] A web laying machine includes a mounting frame, on which a feeding device is mounted for conveying and stacking the web into layers. The mounting frame is also equipped with an adhesive dispensing device for spraying adhesive onto the web conveyed by the feeding device.

[0008] By adopting the above technical solution, the fiber web is transported by the feeding device and stacked into a layered structure. During the stacking process, glue is sprayed onto each layer of fiber web by the glue dispensing device, so that the glue between adjacent layers of fiber web is evenly adhered to the fiber web, thereby improving the uniformity of the glue between the fiber webs.

[0009] In one specific implementation, the glue dispensing device is mounted on a mounting frame and connected to a feeding device. The glue dispensing device includes a mounting tube and a glue dispensing head. The mounting tube is mounted on the feeding device, and the glue dispensing head is mounted on the mounting tube. The glue dispensing head is used to spray glue onto the fiber web in the feeding device.

[0010] By adopting the above technical solution, during the operation of the feeding device, the feeding device drives the installation pipe and the glue dispensing head to move, so that the glue dispensing head can spray glue onto the fiber web, thereby facilitating the bonding between the stacked fiber webs through glue, so as to improve the connection strength between the fiber webs.

[0011] In one specific implementation, the feeding device includes a feeding conveyor belt, a feeding drive mechanism, a folding mechanism, a folding drive mechanism, a carrying conveyor belt, and a carrying drive mechanism. The feeding conveyor belt is installed on the upper end of the mounting frame. The feeding drive mechanism is installed on the mounting frame and connected to the feeding conveyor belt. The folding mechanism and the folding drive mechanism are both installed on the mounting frame and connected to each other. The folding mechanism is also connected to the feeding conveyor belt and a mounting tube. The carrying conveyor belt and the carrying drive mechanism are both installed on the mounting frame. The carrying conveyor belt is located below the folding mechanism and connected to the carrying drive mechanism. The carrying conveyor belt is used to receive stacked fiber webs.

[0012] By adopting the above technical solution, the feeding conveyor belt is driven by the feeding drive mechanism to transport the fiber web to the folding mechanism. The folding drive mechanism then drives the folding mechanism to move back and forth, guiding the fiber web onto the carrier conveyor belt. This facilitates the stacking of the fiber web into a layered structure. The folding mechanism also drives the glue dispensing head to move back and forth, spraying glue onto the fiber web and facilitating its formation. Furthermore, the carrier drive mechanism drives the carrier conveyor belt to transport the layered fiber web, allowing the folding mechanism to continuously guide the fiber web onto the carrier conveyor belt, thus facilitating the formation of a continuous layered fiber web structure.

[0013] In one specific implementation, the dispensing device further includes a quick-release mechanism. The dispensing head is mounted on the mounting tube via the quick-release mechanism. The quick-release mechanism includes a quick-release sleeve, a quick-release rod, and a locking assembly. One end of the quick-release sleeve is mounted on the mounting tube, and the other end extends away from the mounting tube. The quick-release rod is mounted on the dispensing head, and the quick-release sleeve has a conduit communicating with the mounting tube. One end of the quick-release rod is inserted into the quick-release sleeve, and the end of the quick-release rod inside the quick-release sleeve is fitted onto the conduit. The locking assembly is installed in the inner wall of the quick-release sleeve and is used to position the quick-release rod inside the quick-release sleeve. A seal is installed on the conduit, and the seal is used to seal the connection between the conduit and the quick-release rod.

[0014] By adopting the above technical solution, the dispensing head is installed on the installation tube via a quick-release mechanism, facilitating rapid replacement when a new dispensing head is needed, thereby improving the replacement efficiency. The connection between the installation tube and the dispensing head is completed by inserting the quick-release rod into the quick-release sleeve, placing the quick-release rod on the guide tube, and sealing it with a sealing element. When the dispensing head is installed on the quick-release sleeve via the quick-release rod, the quick-release rod is locked by a locking component, thereby improving the stability of the dispensing head installation.

[0015] In one specific implementation, the locking assembly includes a locking ring, a locking spring, a locking rod, a locking hook, and an unlocking element. The locking ring is slidably mounted in the inner wall of the quick-release sleeve along its axial direction. The locking spring is mounted in the inner wall of the quick-release sleeve, with one end connected to the end of the locking ring and the other end connected to the inner wall of the quick-release sleeve. A locking plate is mounted on the end of the locking ring away from the locking spring, and a locking block is mounted on the end of the locking plate away from the locking ring. A locking groove is formed on the side wall of the quick-release rod to engage with the locking block. The inner wall of the quick-release sleeve... The wall is provided with a locking protrusion, which is used to abut against the side wall of the locking piece away from the locking block. The locking rod is installed on the side wall of the locking ring, and one end of the locking rod extends out of the side wall of the quick-release sleeve and is slidably connected to the quick-release sleeve. The other end passes through the inner wall of the quick-release sleeve. The end of the locking rod located inside the quick-release sleeve is used to connect with the quick-release rod. The locking hook is installed on the outer wall of the quick-release sleeve, and the end of the locking rod located outside the quick-release sleeve is connected to the locking hook. The unlocking element is installed on the locking hook, and the unlocking element is also connected to the end of the locking rod located outside the quick-release sleeve.

[0016] By adopting the above technical solution, during the installation of the quick-release lever, the quick-release lever drives the locking ring upward through the locking lever, compressing the locking spring. When the locking ring moves the locking plate until the locking block on the locking plate approaches the locking protrusion, the locking plate undergoes elastic deformation under the action of the locking protrusion, thereby causing the locking block to insert into the locking groove of the quick-release lever. This achieves positioning of the quick-release lever, thus improving the firmness of the connection between the quick-release lever and the quick-release sleeve. After the quick-release lever is inserted into place, the locking hook limits the locking lever, ensuring it remains in its current position so that the locking block can continuously position the quick-release lever.

[0017] In one specific implementation, the unlocking component includes an unlocking block. A control groove for sliding the quick-release lever is provided on the side wall of the quick-release sleeve. A positioning block is installed on the side wall at the upper end of the control groove. A space for storing the quick-release lever is left between the positioning block and the end of the control groove. An mounting plate is installed on the outer side wall of the quick-release sleeve near the positioning block. A locking hook is installed on the upper side of the mounting plate and is used to limit the locking lever. The unlocking block is installed on the other side of the mounting plate and is used to push the quick-release lever away from the positioning block.

[0018] By adopting the above technical solution, when the quick-release lever is inserted into place, it moves the locking lever to the positioning block. The locking lever is located between the end of the positioning block and the control groove, allowing it to be limited by the positioning block. Then, by rotating the mounting plate clockwise, the mounting plate rotates the locking hook, thereby locking the locking lever. When it is necessary to remove the quick-release lever, by rotating the mounting plate counterclockwise, the mounting plate moves the unlocking block against the locking lever, pushing the locking lever away from the positioning block. This allows the locking lever to pass over the positioning block, enabling it to disengage from the quick-release sleeve under the action of the locking spring, thus facilitating the removal of the quick-release lever.

[0019] In one specific implementation, the lower end of the mounting frame is provided with a material ejection mechanism, and there are at least two mounting frames arranged along the length of the material ejection mechanism, and a set of glue dispensing devices is provided between each pair of adjacent mounting frames.

[0020] By adopting the above technical solution and setting at least two mounting frames, it is convenient to simultaneously feed the fiber web into the unloading mechanism through the feeding devices in at least two mounting frames. This facilitates the formation of a layered structure of the fiber web under the conveying of the unloading mechanism. Furthermore, a set of glue dispensing devices is installed between two adjacent mounting frames, which facilitates the uniform spraying of glue onto the fiber web during the conveying process and its stacking into layers under the action of the unloading mechanism. This improves the uniformity of the glue between two adjacent layers of fiber web.

[0021] In one specific implementation, the unloading mechanism is located below the feeding device and is used to receive the fiber web. The unloading mechanism includes an unloading frame, an unloading conveyor belt, and an unloading drive assembly. The unloading frame is located at the lower end of the mounting frame. The unloading conveyor belt and the unloading drive assembly are both mounted on the unloading frame, and the unloading drive assembly is connected to the unloading conveyor belt.

[0022] By adopting the above technical solution, the unloading conveyor belt is driven by the unloading drive component, so that the unloading conveyor belt continuously conveys the fiber web, and the fiber web in at least two mounting frames can be stacked on the unloading conveyor belt to form a layered structure.

[0023] In one specific implementation, the glue dispensing device is installed on one side of the mounting frame and is located above the unloading mechanism. The glue dispensing device includes a nozzle, a glue dispensing frame, and a reciprocating assembly. The glue dispensing frame is disposed on one side of the mounting frame, the reciprocating assembly is mounted on the glue dispensing frame, the nozzle is mounted on the reciprocating assembly, and the nozzle is used to spray glue onto the fiber mesh in the unloading mechanism.

[0024] By adopting the above technical solution, during the process of the fiber web being transported by the unloading conveyor belt, the reciprocating component drives the nozzle to move back and forth, so that the nozzle can evenly spray the adhesive between two adjacent layers of fiber web.

[0025] In one specific implementation, the reciprocating assembly includes a reciprocating motor, a reciprocating gear, a reciprocating frame, and a rack. The reciprocating frame is slidably mounted on the glue dispensing frame, the reciprocating motor is mounted on the glue dispensing frame, the reciprocating gear is coaxially mounted on the output shaft of the reciprocating motor, and the rack is mounted on the glue dispensing frame, with the reciprocating gear meshing with the rack.

[0026] By adopting the above technical solution, the reciprocating motor drives the reciprocating gear to rotate back and forth, so that the reciprocating gear can move along the rack, thereby driving the reciprocating frame to move back and forth along the glue dispensing frame, thereby realizing continuous glue spraying onto the fiber mesh, so as to improve the uniformity of glue spraying.

[0027] In summary, this application includes at least one of the following beneficial effects:

[0028] 1. This application provides a glue dispensing device, which facilitates the spraying of glue onto the fiber web, thereby ensuring that glue is sprayed between adjacent layers of the fiber web in the formed layered structure, thus improving the uniformity of the glue in the formed fiber web.

[0029] 2. This application incorporates a quick-release mechanism to facilitate rapid replacement of the dispensing head, thereby improving the efficiency of dispensing head replacement.

[0030] 3. This application, by setting a reciprocating component, facilitates the reciprocating movement of the nozzle, thereby making it easier to spray adhesive onto the fiber web during transportation and thus improving the adhesive coverage on the fiber web. Attached Figure Description

The glue sprayed from the two glue dispensing heads 32 on the same positioning rod 284 forms a continuous straight line.

[0051] Reference Figure 4 and Figure 5 The quick-release mechanism 33 includes a quick-release sleeve 331, a quick-release rod 333, and a locking assembly 334. One end of the quick-release sleeve 331 is fixedly installed at the lower end of the mounting tube 31, and the other end extends downwards, as shown in the figure. Figure 4 and Figure 6 A guide tube 332 is fixedly installed inside the quick-release sleeve 331. One end of the guide tube 332 is connected to the mounting tube 31, and the other end is used to connect to the dispensing head 32. A gap is left between the outer wall of the guide tube 332 and the inner wall of the quick-release sleeve 331. (Refer to...) Figure 6 and Figure 7 The quick-release lever 333 is tubular, with one end fixedly mounted on the dispensing head 32 and the other end inserted into the quick-release sleeve 331 and fitted onto the guide tube 332. A locking assembly 334 is mounted on the quick-release sleeve 331 and is used to position the quick-release lever 333. A seal, including a sealing ring 335, is also installed inside the quick-release sleeve 331. The sealing ring 335 is fitted onto the guide tube 332 and located between the outer wall of the guide tube 332 and the inner wall of the quick-release sleeve 331, sealing the connection between the guide tube 332 and the quick-release lever 333.

[0052] Reference Figure 6 and Figure 7The locking assembly 334 includes a locking ring 3341, a locking spring 3342, a locking rod 3343, a locking hook 3344, and an unlocking component. A mounting groove 3311 is formed in the inner wall of the quick-release sleeve 331 along its length. The locking ring 3341 is slidably mounted in the mounting groove 3311 along the axial direction of the quick-release sleeve 331. A locking piece 3347 is fixedly mounted on one end of the locking ring 3341 near the quick-release rod 333. The locking piece 3347 is elastic, with one end located near the axis of the locking ring 3341 at its end, and the other end tilted away from the axis of the locking ring 3341. Extending diagonally downwards, a locking block 3348 is fixedly installed on the side wall of the locking piece 3347 away from the locking ring 3341. The locking block 3348 is located on the side of the locking piece 3347 near the axis of the locking ring 3341. The cross-section of the locking block 3348 is a right triangle, and one end of the hypotenuse of the triangle extends upwards from the side wall of the locking piece 3347 away from the locking piece 3347. A locking groove 3331 for the locking block 3348 to be inserted is provided on the side wall of the quick release lever 333. A notch for the locking block 3348 to slide is provided on the side wall of the mounting groove 3311 in the quick release sleeve 331 near the axis of the quick release sleeve 331.

[0053] Reference Figure 6 and Figure 7 A locking spring 3342 is installed in the mounting groove 3311, with one end of the locking spring 3342 abutting against the end of the locking ring 3341 away from the locking piece 3347, and the other end abutting against the inner top wall of the mounting groove 3311. A locking protrusion 3349 is fixedly installed on the inner wall of the mounting groove 3311 on the side away from the axis of the quick-release sleeve 331. The locking protrusion 3349 is annular and is used to abut against the locking piece 3347. A locking rod 3343 is fixedly installed on the side wall of the locking ring 3341, with one end of the locking rod 3343 extending into the notch, and the other end passing through the side wall of the locking ring 3341 and the outer side wall of the quick-release sleeve 331 and extending outward. The end of the quick-release rod 333 near the quick-release sleeve 331 has an insertion groove for the locking rod 3343 to be inserted.

[0054] Reference Figure 6 and Figure 8The outer wall of the quick-release sleeve 331 is provided with a control groove 3312 for sliding the locking rod 3343. The control groove 3312 includes a straight part and a spiral part. One end of the straight part extends upward from the end of the quick-release sleeve 331 near the end of the quick-release rod 333. One end of the spiral part is connected to the upper end of the straight part, and the other end extends spirally upward. A positioning block 3313 is fixedly installed on the bottom wall of the spiral part of the control groove 3312. A space for storing the locking rod 3343 is left between the positioning block 3313 and the end of the spiral part, and a gap is left between the end of the positioning block 3313 and the top wall of the spiral part for the locking rod 3343 to pass through. An mounting plate 3345 is rotatably mounted on the upper end of the spiral part near the control groove 3312 on the outer side wall of the quick-release sleeve 331. One end of the locking hook 3344 is fixedly mounted on one side of the mounting plate 3345, and the other end of the locking hook 3344 extends away from the mounting plate 3345. The locking hook 3344 is used to limit the locking rod 3343.

[0055] Reference Figure 6 and Figure 8 The unlocking component includes an unlocking block 3346, which is fixedly mounted on the other side of the mounting plate 3345 and is used to push the locking lever 3343 away from the locking block 3348.

[0056] Reference Figure 7 and Figure 8 By aligning the locking groove 3331 at the end of the quick-release lever 333 with the locking lever 3343, and inserting the quick-release lever 333 into the quick-release sleeve 331, the end of the quick-release lever 333 pushes the locking lever 3343 upward, thereby causing the locking lever 3343 to move the locking ring 3341 upward and compress the locking spring 3342. Simultaneously, the locking lever 3343 slides upward along the straight portion of the control groove 3312 into the helical portion. During this process, refer to... Figure 6 and Figure 7 The locking ring 3341 drives the locking piece 3347 to move upward, so that the locking piece 3347 moves to the side wall of the end away from the locking ring 3341 and abuts against the locking protrusion 3349, thereby deforming the locking piece 3347, which in turn drives the locking block 3348 to move in the direction of the quick release lever 333, so that the locking block 3348 is inserted into the locking groove 3331.

[0057] Reference Figure 6 and Figure 7 When the quick-release lever 333 moves to the position where it is fitted onto the guide tube 332 and abuts against the sealing ring 335, the locking block 3348 remains inserted into the locking groove 3331 on the quick-release lever 333, thereby locking the quick-release lever 333. (Refer to...) Figure 7 and Figure 8Then, release the quick-release lever 333, causing the locking ring 3341 to move downwards under the action of the locking spring 3342. This moves the locking lever 3343 to the position between the positioning block 3313 and the end of the spiral portion of the control groove 3312, where it is limited by the positioning block 3313. Then, by rotating the mounting plate 3345 clockwise, the locking hook 3344 on the mounting plate 3345 rotates to the locking lever 3343, locking the locking lever 3343 and thus facilitating the stability of the locking lever 3343.

[0058] Reference Figure 7 and Figure 8 By rotating the mounting plate 3345 counterclockwise, the locking hook 3344 is separated from the locking rod 3343, thereby releasing the locking hook 3344 from locking the locking rod 3343. Then, by continuing to rotate the mounting plate 3345 counterclockwise, the unlocking block 3346 on the mounting plate 3345 abuts against the locking rod 3343 and pushes the locking rod 3343 upward. While the mounting plate 3345 drives the unlocking block 3346 to rotate, the unlocking block 3346 also pushes the locking rod 3343 away from the mounting plate 3345, so that the locking rod 3343 passes the end of the positioning block 3313, thereby pushing the locking rod 3343 away from the positioning block 3313.

[0059] Reference Figure 7 and Figure 8 When the locking lever 3343 separates from the unlocking block 3346, the locking ring 3341 moves downward to reset under the action of the locking spring 3342. This causes the locking ring 3341 to drive the locking lever 3343 to slide along the spiral part of the control groove 3312 to the straight part. This causes the locking lever 3343 to drive the quick-release lever 333 to separate from the guide tube 332, and to move the quick-release lever 333 away from the quick-release sleeve 331. (Refer to...) Figure 6 and Figure 7 When the locking ring 3341 moves to near the locking protrusion 3349 under the action of the locking spring 3342, the locking piece 3347 restores its deformation, thereby causing the locking piece 3347 to drive the locking block 3348 to move away from the quick release lever 333, thereby separating the locking block 3348 from the locking groove 3331, thereby releasing the lock on the quick release lever 333, thus realizing the action of removing the quick release lever 333 from the quick release sleeve 331.

[0060] The working principle of this embodiment is as follows: the feeding drive mechanism 23 drives the feeding conveyor belt 22 to operate, thereby conveying the fiber web onto the mounting frame 1. The feeding drive mechanism 25 drives the feeding conveyor belt 24 to operate, thereby conveying the fiber web between the two discharge rollers 282 in the folding mechanism 28. The folding drive mechanism 283 drives the folding frame 281 to slide back and forth along the mounting frame 1, thereby driving the fiber web to move back and forth, thereby folding and stacking the fiber web onto the carrying conveyor belt 26. During the reciprocating movement of the folding frame 281, glue is sprayed onto the fiber web through the glue dispensing head 32, so that the fiber web stacked on the carrying conveyor belt 26 is evenly sprayed with glue and forms a layered fiber web structure, thereby improving the uniformity of glue spraying on the fiber web.

[0061] When the dispensing head 32 becomes clogged after a period of use or needs to be replaced with a different model, the mounting plate 3345 is rotated counterclockwise. This causes the mounting plate 3345 to drive the unlocking block 3346, pushing the locking rod 3343 away from the positioning block 3313. The locking rod 3343 then passes the end of the positioning block 3313, unlocking the locking rod 3343. The locking ring 3341, under the action of the locking spring 3342, then drives the locking rod 3343 to slide away from the locking spring 3342. This causes the locking rod 3343 to push the quick-release rod 333 away from the guide tube 332, allowing the quick-release rod 333 to exit the quick-release sleeve 331. When the locking ring 3341 moves to the locking protrusion 3349, the locking piece 3347 returns to its elastic deformation, causing the locking block 3348 to separate from the locking groove 3331 on the quick-release rod 333, thus unlocking the quick-release rod 333 for easy removal.

[0062] After replacing the dispensing head 32, align the insertion slot at the end of the quick-release lever 333 on the dispensing head 32 with the locking lever 3343, and re-insert the quick-release lever 333 into the quick-release sleeve 331. This pushes the locking lever 3343 towards the locking spring 3342, thereby causing the locking ring 3341 to move towards the locking spring 3342 and compress the locking spring 3342. The locking ring 3341 causes the locking piece 3347 to move upward, and the locking piece 3347 slides along the locking protrusion 3349 and deflects towards the axis of the quick-release sleeve 331, thereby causing elastic deformation and causing the locking block 3348 to insert into the locking groove 3331 of the quick-release lever 333, thus limiting the quick-release lever 333.

[0063] When the quick-release lever 333 is placed on the conduit 332 and the sealing ring 335 is compressed, the quick-release lever 333 pushes the locking lever 3343 to slide into the spiral part of the control groove 3312, and causes the locking lever 3343 to slide along the top wall of the spiral part to the end of the positioning block 3313, thereby moving to the position between the positioning block 3313 and the end of the spiral part. Then the quick-release lever 333 is released, and the locking ring 3341 moves downward under the action of the locking spring 3342, thereby driving the locking lever 3343 to move downward, so that the locking lever 3343 abuts against the bottom wall of the spiral part and is limited by the positioning block 3313, thereby facilitating the positioning of the locking lever 3343 in the current position, so that the quick-release lever 333 is kept on the conduit 332. Then rotate the mounting plate 3345 clockwise, causing the mounting plate 3345 to drive the locking hook 3344 to rotate, so that the side wall of the locking hook 3344 near the mounting plate 3345 abuts against the side wall of the locking rod 3343, thereby limiting the locking rod 3343 and keeping the locking rod 3343 stationary in the current position, so that the dispensing head 32 can be stably installed on the mounting tube 31.

[0064] Example 2:

[0065] The difference between this embodiment and Embodiment 1 is that, referring to... Figure 9 The lower end of the mounting frame 1 is also provided with a material ejection mechanism 4. There are three mounting frames 1, and the three mounting frames 1 are arranged along the length of the material ejection mechanism 4. Each mounting frame 1 is equipped with a feeding device 2. The glue dispensing device 3 is mounted on the material ejection mechanism 4, and a set of glue dispensing devices 3 is provided between every two adjacent mounting frames 1.

[0066] Reference Figure 9 The unloading mechanism 4 includes an unloading rack 41, an unloading conveyor belt 42, and an unloading drive assembly (not shown in the figure). The unloading rack 41 is located below the carrying conveyor belt 26, and the unloading conveyor belt 42 is mounted on the unloading rack 41 and is used to transport the fiber web. The unloading drive assembly is mounted on the unloading rack 41 and is connected to the unloading conveyor belt 42. The unloading drive assembly is prior art in this field and will not be described in detail here.

[0067] Reference Figure 9 and Figure 10The glue dispensing device 3 includes a nozzle 34, a glue dispensing frame 35, and a reciprocating assembly 36. The glue dispensing frame 35 is fixedly mounted above the unloading conveyor belt 42. The reciprocating assembly 36 includes a reciprocating motor 361, a reciprocating gear 362, a reciprocating frame 363, and a rack 364. The reciprocating frame 363 is slidably mounted on the side wall of the unloading frame 41 along its length. The reciprocating motor 361 is fixedly mounted on the side wall of the reciprocating frame 363. The reciprocating gear 362 is coaxially mounted on the output shaft of the reciprocating motor 361. The rack 364 is fixedly mounted on the top wall of the glue dispensing frame 35 along its length, and the rack 364 meshes with the reciprocating gear 362. The nozzle 34 is fixedly mounted on the reciprocating frame 363 and extends downwards. The nozzle 34 is used to spray glue onto the unloading conveyor belt 42.

[0068] The working principle of this embodiment is as follows: Three sets of feeding devices 2 simultaneously feed the fiber web onto the unloading conveyor belt 42. The unloading drive assembly drives the unloading conveyor belt 42, causing the fiber web to form a three-layer stacked structure during transport. While the fiber web is being transported by the unloading conveyor belt 42, a reciprocating motor 361 continuously drives the reciprocating gear 362 to rotate forward and backward, causing the reciprocating gear 362 to move back and forth along the rack 364. This, in turn, drives the reciprocating frame 363 to move back and forth along the length of the glue dispensing frame 35, thereby driving the nozzle 34 to move back and forth. The nozzle 34 then sprays glue onto the fiber web on the unloading conveyor belt 42. This ensures that when the fiber web is stacked into a three-layer structure under the transport of the unloading conveyor belt 42, glue is sprayed between adjacent layers, thus improving the uniformity of the glue in the formed fiber web.

[0069] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be included within the scope of protection of this application.
