[0002] The tail filter of a hair dryer has a three-layer stacked structure consisting of two layers of large-pore steel mesh sandwiched in the middle with a layer of fine-pore yarn mesh.

[0003] During assembly, the fine-mesh mesh must first be punched, then the lower layer of large-mesh steel mesh is fixed, and then the punched fine-mesh mesh and the upper layer of large-mesh steel mesh are sequentially stacked on top of the lower layer of large-mesh steel mesh. Finally, the three layers of mesh are heat-fused to secure them. The entire assembly process involves multiple steps, including punching fine-mesh mesh, stacking materials, fixing the materials, and heat-fusion. The steps are complex, and a firm assembly is required. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the technical problem to be solved by the present invention is to provide a hair dryer filter assembly equipment, which can conveniently and quickly perform the processes of cutting fine mesh sheets, stacking materials, fixing and installing materials, and hot-melting the tail filter of hair dryers, thereby improving the overall production efficiency of the product.

[0005] To achieve the above objectives, the present invention provides a hair dryer filter assembly device, comprising:

[0006] A wire mesh feeding structure is used to store multiple stacked large-hole wire mesh sheets and can separate the large-hole wire mesh sheets individually.

[0007] The tray loading structure includes a first conveyor belt for forward conveying of the trays at intervals;

[0008] Assembly structure; disposed on the first conveyor belt conveyor line, including two clamping claws and a clamping drive source, the two clamping claws are arranged opposite each other in a conveying direction perpendicular to the first conveyor belt, the clamping drive source is connected to the two clamping claws, and can drive the two clamping claws to move closer to each other so that the two notches form a receiving cavity, the first conveyor belt can convey the bracket to the receiving cavity and be clamped by the two clamping claws;

[0009] A robotic arm is used to stack the individual large-hole steel mesh sheets separated from the steel mesh feeding structure onto the bracket inside the receiving cavity;

[0010] A mesh processing and feeding structure is used for punching out fine-mesh mesh sheets, and can transfer and stack the punched fine-mesh mesh sheets onto large-mesh steel mesh sheets at the assembly structure station; and

[0011] A hot-melt pressing mechanism is installed above the first conveyor belt. The hot-melt head of the hot-melt pressing mechanism can hot-press the bracket, the large-hole steel mesh and the fine-hole yarn mesh that are stacked on the assembly structure station together.

[0012] Furthermore, the assembly structure also includes a guide member, which includes a first elastic member and a guide plate. The clamping claw has a slot communicating with the notch along its radial direction. The guide plate can be slidably inserted into the slot through the first elastic member, and the end of the guide plate extends out of the slot. The end of the guide plate gradually increases in size from the side near the central axis of the notch outwards, and the maximum point is adapted to the corresponding slot size of the bracket located in the receiving cavity. The end of the guide plate is flush with the inner wall of the bracket located in the receiving cavity.

[0013] Furthermore, the wire mesh feeding structure includes a worktable, a material cylinder, a pusher plate, and an ejection drive source. Both the upper and lower ends of the material cylinder are open. The material cylinder is suspended on the worktable by a bracket, and the height of the bottom end of the material cylinder from the worktable is the thickness of a single large-hole wire mesh sheet. Multiple large-hole wire mesh sheets are stacked from bottom to top inside the material cylinder. The ejection drive source is located on the worktable, and the pusher plate is located on the output shaft of the ejection drive source. The pusher plate can drive the pusher plate to pass between the material cylinder and the worktable, pushing the large-hole wire mesh sheets on the worktable away from below the material cylinder.

[0014] Furthermore, the mesh processing and feeding structure includes:

[0015] First rack;

[0016] A punching device includes a punching mechanism, a cutting die, and a die base. The punching mechanism and the die base are disposed opposite to each other on the first frame. The cutting die is mounted on the punching mechanism. The end face of the cutting die facing the die base has a punching hole. The length of the punched flexible fine-mesh mesh is greater than the diameter of the punching hole in at least one direction.

[0017] The feeding device includes a first feeding mechanism, which is mounted on the first frame. The first feeding mechanism is used to push the fine-mesh mesh into the punching hole, so that the fine-mesh mesh, whose length in one direction is greater than the diameter of the punching hole, is bent and deformed and locked into the punching hole; and

[0018] A feeding mechanism is mounted on the frame and connected to the stamping mechanism, used to drive the stamping mechanism to move from the punching station to the next station.

[0019] Furthermore, the punching device also includes an intermediate lifting mechanism, the telescopic shaft of the intermediate lifting mechanism is coaxially arranged with the telescopic shaft of the stamping mechanism, and the telescopic shaft of the intermediate lifting mechanism extends from both ends, and one end of the telescopic shaft of the intermediate lifting mechanism can abut against the telescopic shaft of the stamping mechanism, and the cutting die is connected to one end of the telescopic shaft of the intermediate lifting mechanism.

[0020] Furthermore, the mold base has a first through hole that passes through the mold base, the mold base is placed on the first frame, and the worktable has a second through hole that passes through the worktable. The second through hole is correspondingly arranged with the first through hole. The first pushing mechanism includes a loading telescopic power source and a support plate. The loading telescopic power source is mounted on the first frame through a bracket, and the support plate is mounted on the telescopic shaft of the support plate. The loading telescopic power source can drive the support plate to pass through the second through hole and the first through hole and then extend into the punching hole.

[0021] Furthermore, the pushing device also includes a second pushing mechanism, which includes a pressing telescopic power source and a pressure plate. The pressing telescopic power source is disposed inside the punching hole, and the pressure plate is disposed on the telescopic shaft of the pressing telescopic power source. The outer diameter of the pressure plate is smaller than the inner diameter of the punching hole, and the pressing telescopic power source can drive the pressure plate to rise and fall perpendicularly to the mold base.

[0022] Furthermore, the material pushing device also includes a scissor die pad, which is supported in the mounting groove by a shock-absorbing pad. The mold base has a mounting groove coaxial with the first perforation on the side facing the scissor die. The scissor die pad is disposed in the mounting groove and is flush with the surface of the mold base.

[0023] Furthermore, the feeding mechanism includes a movable mounting plate and a movable drive source. The movable drive source is mounted on the first frame, and the movable mounting plate is on the power output shaft of the movable drive source. The movable drive source can drive the movable mounting plate to move to a lower station.

[0024] Furthermore, the hot melt head is an annular head, and an elastic telescopic clamping member is provided inside the cavity of the hot melt head, with the end of the elastic telescopic clamping member extending from the bottom end of the hot melt head.

[0025] This type of hair dryer filter assembly equipment is used:

[0026] In use, the prefabricated large-hole steel mesh sheets are first stacked and placed into the steel mesh feeding structure. The mesh processing and feeding structure starts the fine-hole mesh sheet punching process, and at the same time, the tray is fed on the first conveyor belt. After the clamping drive source drives the two clamping jaws to separate, the first conveyor belt transports the bracket forward into the notch. Then, the clamping drive source drives the two clamping jaws to close and hold the bracket tightly. Next, the robot arm picks up the individual large-hole steel mesh sheets separated from the steel mesh feeding structure, transfers them, and stacks them on the bracket, aligning the holes or protrusions on the large-hole steel mesh sheets with the protrusions or holes on the bracket. Then, the mesh processing feeding structure begins to process the fine-hole mesh sheets, and transfers and stacks the processed fine-hole mesh sheets onto the large-hole steel mesh sheets at the assembly structure station. Then, the robot arm again transfers the large-hole steel mesh sheets from the steel mesh feeding structure to the fine-hole mesh sheets, while aligning the holes or protrusions on the large-hole steel mesh sheets with the protrusions or holes on the bracket. Finally, the hot melt pressing head of the hot melt pressing mechanism descends to hot press the stacked bracket, the lower large-hole steel mesh sheet, the fine-hole mesh sheet, and the upper large-hole steel mesh sheet together at the assembly structure station to complete the assembly. Next, the clamping drive source drives the two clamping claws to separate, and the first conveyor belt starts to transport the assembled filter screen forward, so that the assembly of the next filter screen can be carried out.

[0027] The aforementioned hair dryer filter assembly equipment can not only punch and cut fine mesh sheets, but also conveniently and quickly assemble the tail filter of the hair dryer, thereby improving the overall production efficiency of the product. Attached Figure Description

[0051] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0052] Please see Figures 1 to 11 A hair dryer filter assembly device includes a steel mesh feeding structure 100, a bracket feeding structure 200, an assembly structure 300, a robotic arm 400, a mesh processing and feeding structure 500, and a hot melt pressing mechanism 600, used to assemble a bracket, two layers of large-hole steel mesh and one layer of fine-hole mesh into a hair dryer filter.

[0053] Specifically, the steel mesh feeding structure 100 is used to store multiple large-hole steel mesh sheets and can separate the large-hole steel mesh sheets individually. The bracket feeding structure 200 includes a first conveyor belt for conveying the brackets forward at intervals. The assembly structure 300 is set on the first conveyor belt conveyor line and includes two clamping claws 310 and a clamping drive source 320. The two clamping claws 310 are arranged opposite each other in a conveying direction perpendicular to the first conveyor belt. The clamping drive source 320 is connected to the two clamping claws 310 and can drive the two clamping claws 310 to move closer to each other so that the two notches form a receiving cavity. The first conveyor belt can convey the brackets into the receiving cavity and clamp them by the two clamping claws 310.

[0054] The robotic arm 400 is used to stack individual large-hole steel mesh sheets separated from the steel mesh feeding structure 100 onto the brackets inside the receiving cavity. The mesh processing and feeding structure 500 is used to punch out fine-hole mesh sheets and can transfer and stack the punched fine-hole mesh sheets onto the large-hole steel mesh sheets at the assembly structure 300 station. The hot-melt pressing mechanism 600 is located above the first conveyor belt, and the hot-melt head 610 of the hot-melt pressing mechanism 600 can hot-press the stacked brackets, large-hole steel mesh sheets, and fine-hole mesh sheets conveyed from the assembly structure 300 station together.

[0055] In use, pre-fabricated large-hole steel mesh sheets are first stacked and placed into the steel mesh feeding structure 100. The mesh processing feeding structure 500 starts the fine-hole mesh sheet punching process, while the tray is fed on the first conveyor belt. When the clamping drive source 320 drives the two clamping jaws 310 to separate, the first conveyor belt transports the tray forward into the notch. Then, the clamping drive source 320 drives the two clamping jaws 310 to close and clamp the tray. Next, the robot arm 400 picks up the individual large-hole steel mesh sheets separated from the steel mesh feeding structure 100, transfers and stacks them on the tray, aligning the holes or protrusions on the large-hole steel mesh sheets with the protrusions or holes on the tray. Then, the mesh processing feeding structure 500 starts the fine-hole mesh sheet processing and feeds the processed mesh sheets... Fine-mesh mesh is transferred and stacked onto large-mesh steel mesh at assembly station 300. Then, robotic arm 400 transfers the large-mesh steel mesh from the feed structure 100 to the fine-mesh mesh. Simultaneously, the holes or protrusions on the large-mesh steel mesh must be aligned with the protrusions or holes on the bracket. Finally, the hot-melt pressing head 610 of the hot-melt pressing mechanism 600 descends to hot-press the stacked bracket, lower large-mesh steel mesh, fine-mesh mesh, and upper large-mesh steel mesh together at assembly station 300 to complete the assembly. Next, clamping drive source 320 drives the two clamping jaws 310 to separate, and the first conveyor belt starts, transporting the assembled filter screen forward, allowing the assembly of the next filter screen to begin.

[0056] The aforementioned hair dryer filter assembly equipment can not only punch and cut fine mesh sheets, but also conveniently and quickly assemble the tail filter of the hair dryer, thereby improving the overall production efficiency of the product.

[0057] It should be noted that in this application, the steel mesh feeding structure 100, the bracket feeding structure 200, the assembly structure 300, the robot arm 400, the mesh processing feeding structure 500, and the hot-melt pressing mechanism 600 are all communicatively connected and controlled by the same controller. During the processing, they should be coordinated and configured according to the processing time of each step to complete the entire production line. Furthermore, in specific implementation, the separated individual large-hole steel mesh sheets can be positioned on a glass plate. A digital camera device is installed below the glass plate to read the coordinates and angular orientation of the large-hole steel mesh sheets (the steel mesh sheets have different notches such as notches that can be used for coordinate and angular positioning) and transmit this information to the controller to control the robot arm 400. This ensures that the brackets located in the receiving cavity are in the correct positions, facilitating the alignment of the large-hole steel mesh sheets, fine-hole mesh sheets, and brackets, and smoothly completing the hot-melt pressing process.

[0058] Please refer to Figure 2 In a preferred embodiment, the assembly structure 300 further includes a guide member 330, which includes a first elastic member and a guide plate. A slot communicating with a notch is provided radially on the clamping claw 310. The guide plate is slidably inserted into the slot via the first elastic member, with its end extending out of the slot. The end of the guide plate gradually increases in size from the side closest to the central axis of the notch, and its maximum size matches the corresponding slot size of the bracket located in the receiving cavity. The end of the guide plate is flush with the inner wall of the bracket located in the receiving cavity.

[0059] In use, when the two clamping claws 310 come together, the outer end of the guide plate extends into the notch, so it can be inserted into the corresponding slot of the bracket located in the receiving cavity. If the bracket deviates slightly from the preset position, the bracket can be driven to rotate or move slowly under the action of the two guide plates until the bracket is in the correct position.

[0060] Please refer to Figure 3 In this embodiment, the wire mesh feeding structure 100 includes a workbench 110, a material cylinder 120, a pusher plate 130, and an ejection drive source 140. Both the upper and lower ends of the material cylinder 120 are open. The material cylinder 120 is suspended on the workbench 110 by a bracket. The height of the bottom end of the material cylinder 120 from the workbench 110 is the thickness of a single large-hole wire mesh sheet. Multiple large-hole wire mesh sheets are stacked from bottom to top inside the material cylinder 120. The ejection drive source 140 is set on the workbench 110. The pusher plate 130 is set on the output shaft of the ejection drive source 140. It can drive the pusher plate 130 to pass between the material cylinder 120 and the workbench 110, pushing the large-hole wire mesh sheets on the workbench 110 away from below the material cylinder 120.

[0061] In use, when the drive source 140 is activated, it drives the push plate 130 to move back and forth between the material cylinder 120 and the worktable 110, pushing the large-hole steel mesh on the worktable 110 away from below the material cylinder 120. This achieves the distribution of the large-hole steel mesh.

[0062] In specific implementation, the ejection drive source 140 can be a linear motion drive source. When the drive push plate 130 moves radially along the material cylinder 120, it can eject a single large-hole steel mesh sheet. Of course, the ejection drive source can also be a rotary motion drive source. When the drive arc sweeps across the bottom of the material cylinder 120, it can also eject a single large-hole steel mesh sheet.

[0063] Please see Figure 4-11 In this embodiment, the mesh processing feeding structure 500 includes a first frame 510, a punching device 520, a pushing device 530, and a feeding mechanism 540.

[0064] Specifically: The punching device 520 includes a punching mechanism 521, a cutting die 522, and a die base 523. The punching mechanism 521 and the die base 523 are arranged opposite to each other on the first frame 510. The cutting die 522 is mounted on the punching mechanism 521. The end face of the cutting die 522 facing the die base 523 has a punching hole. The length of the flexible fine-mesh mesh sheet punched out is greater than the diameter of the punching hole in at least one direction. The pushing device 530 includes a first pushing mechanism 531, which is arranged on the first frame 510. The first pushing mechanism 531 is used to push the fine-mesh mesh sheet into the punching hole so that the fine-mesh mesh sheet with a length greater than the diameter of the punching hole in one direction is bent and deformed and stuck in the punching hole. The feeding mechanism 540 is arranged on the frame and connected to the punching mechanism 521, and is used to drive the punching mechanism 521 to move from the punching station to the next station.

[0065] In use, when the strip of fine-mesh mesh is placed on the die base 523, the stamping mechanism 521 drives the cutting die 522 to move towards the die base 523 for punching and cutting. Subsequently, the pushing device 530 grabs the punched fine-mesh mesh back into the punching hole. Since the fine-mesh mesh is flexible, during the punching process, it can be stretched and squeezed, thereby causing the edges of the fine-mesh mesh to flare outward, so that the length of the fine-mesh mesh is greater than the diameter of the punching hole in at least one direction. Then, after the pushing device 530 grabs the punched fine-mesh mesh back into the punching hole, the fine-mesh mesh will be stuck in the punching hole for temporary storage.

[0066] Using this punching device 520 eliminates the need for additional material handling equipment. This device integrates punching, material handling, and feeding, which reduces both the production process and production costs.

[0067] In practical implementation, the stamping mechanism 521 can be a cylinder, hydraulic cylinder, lead screw, or other mechanism that can achieve linear pressurization.

[0068] Please continue reading Figure 4-11 In a preferred embodiment, the punching device 520 further includes an intermediate lifting mechanism 524. The telescopic shaft of the intermediate lifting mechanism 524 is coaxially arranged with the telescopic shaft of the punching mechanism 521, and the telescopic shaft of the intermediate lifting mechanism 524 extends from both ends. One end of the telescopic shaft of the intermediate lifting mechanism 524 can abut against the telescopic shaft of the punching mechanism 521. The cutting mold 522 is connected to one end of the telescopic shaft of the intermediate lifting mechanism 524.

[0069] It should be noted that the intermediate lifting mechanism 524 can be any other mechanism that can achieve linear pressurization, such as a cylinder, hydraulic cylinder, or lead screw.

[0070] The specific working process is as follows: When in use, the telescopic shaft of the intermediate lifting mechanism 524 drives the cutting die 522 to move closer to the die base 523 until the cutting die 522 abuts against the strip 1. Then, the telescopic shaft of the stamping mechanism 521 extends and abuts against the other end of the telescopic shaft of the intermediate lifting mechanism 524, thereby driving the intermediate lifting mechanism 524 and the cutting die 522 on it to move and punch the strip 1.

[0071] By using this method, the entire stamping stroke can be reduced and stamping stability can be improved through the two-stage pressure application of the intermediate lifting mechanism 524 and the stamping mechanism 521, thereby improving the stamping quality.

[0072] Please continue reading Figure 4-11 In this embodiment, the feeding mechanism 540 includes a movable mounting plate 541 and a movable drive source 542. The movable drive source 542 is mounted on the first frame 510, and the movable mounting plate 541 is on the power output shaft of the movable drive source 542. The movable drive source 542 can drive the movable mounting plate 541 to move to a lower station.

[0073] In specific implementation, the mobile drive source 542 can be a cylinder, hydraulic cylinder, lead screw or other mechanism capable of linear drive, or it can be a curve-advancing or rotary mechanism.

[0074] When the mobile drive source 542 can be a cylinder, hydraulic cylinder, lead screw or other mechanism that can perform linear drive, the end of the mobile mounting plate 541 that is away from the cutting mold 522 can be slidably supported on the first frame 510, which can improve the movement stability of the mobile mounting plate 541.

[0075] In this embodiment, a first through hole is formed in the mold base 523, and a second through hole 111 is formed in the worktable 110, with the first through hole and the second through hole corresponding to each other. The first pushing mechanism 531 includes a loading telescopic power source 5311 and a support plate 5312. The loading telescopic power source 5311 is mounted on the first frame 510 via a bracket. The support plate 5312 is mounted on the telescopic shaft of the support plate 5312, and the loading telescopic power source 5311 can drive the support plate 5312 to pass through the second through hole and the first through hole and then extend into the punching hole.

[0076] After the punching is completed, the loading telescopic power source 5311 drives the support plate 5312 to push the fine mesh into the punching hole. Based on the flexible fine mesh's own certain stretching ability, when the edge of the fine mesh moves upward against the side wall of the punching hole, it forms a downward bending deformation. After the first pushing mechanism 531 retracts, the fine mesh forms an upward arch with a certain elasticity and naturally gets stuck in the punching hole.

[0077] It should be noted that, in specific implementation, the punching hole can be a straight cylinder of the same size at the top and bottom, or a cone shape that is larger on the outside and smaller on the inside.

[0078] Please continue reading Figure 4-11 In a preferred embodiment, the feeding device 530 further includes a second feeding mechanism 532. Specifically, the second feeding mechanism 532 includes a pressure-pressing telescopic power source 5321 and a pressure plate 5322. The pressure-pressing telescopic power source 5321 is disposed within the punching hole. The pressure plate 5322 is disposed on the telescopic shaft of the pressure-pressing telescopic power source 5321, and the outer diameter of the pressure plate 5322 is smaller than the inner diameter of the punching hole. The pressure-pressing telescopic power source 5321 can drive the pressure plate 5322 to rise and fall perpendicularly to the die base 523.

[0079] After the punching is completed, the second pushing mechanism 532 and the first pushing mechanism 531 move simultaneously toward the fine-mesh mesh to clamp it. Then, the second pushing mechanism 532 retracts and the first pushing mechanism 531 continues to extend, pushing the fine-mesh mesh into the punching hole. Subsequently, the telescopic shaft of the punching mechanism 521 retracts, the intermediate lifting mechanism 524 retracts, the second pushing mechanism 532 retracts, and the first pushing mechanism 531 continues to extend, pushing the fine-mesh mesh into the punching hole of the cutting mold 522. Based on the flexible fine-mesh mesh's own certain stretching capacity, when the edge of the fine-mesh mesh moves upward against the side wall of the punching hole, it forms a downward bending deformation. After the first pushing mechanism 531 retracts, the fine-mesh mesh forms an upward arch with a certain elasticity and naturally gets stuck inside the punching hole. When it is necessary to push out the fine mesh fabric, the loading telescopic power source 5311 and the support plate 5312 retract, and the pressing telescopic power source 5321 drives the pressure plate 5322 to push the fine mesh fabric out of the punching hole.

[0080] In use, the pressing telescopic power source 5321 and the loading telescopic power source 5311 can drive the pressure plate 5322 and the support plate 5312 to move, thereby driving the fine-mesh mesh sheet to move. It should be noted that, in specific implementations, both the pressing telescopic power source 5321 and the loading telescopic power source 5311 can be selected from other mechanisms commonly used in the prior art, such as cylinders, hydraulic cylinders, and lead screws, that can achieve linear pressure.

[0081] As a preferred embodiment, in specific implementation, both the pressure plate 5322 and the support plate 5312 can be provided with vertically penetrating air holes to allow air to pass through the pressure plate 5322 and the support plate 5312, thereby eliminating the situation where the fine mesh fabric is carried out due to the power generated by the airflow when the pressure plate 5322 and the support plate 5312 move up and down.

[0082] Please continue reading Figure 4-11 As another preferred embodiment, the mesh processing feeding structure 500 may also include a cutting die pad 700. The die base 523 has a mounting groove coaxial with the first perforation on the side facing the cutting die 522. The cutting die pad 700 is disposed in the mounting groove and is flush with the surface of the die base 523.

[0083] When in use, the shearing die pad 700 can be replaced as needed, without having to replace the entire die base 523, thus saving costs.

[0084] Alternatively, the shearing die pad 700 can be supported in the mounting groove by the shock-absorbing pad 800. The shock-absorbing pad 800 can buffer the shearing die pad 700, thereby extending the service life of the shearing die pad 700.

[0085] The entire working process of the mesh processing and feeding structure is as follows:

[0086] First, the intermediate lifting mechanism 524 extends downward, causing the cutting die 522 to abut against the strip of fine-mesh mesh (see...). Figure 4 );

[0087] 2. The stamping telescopic power source extends downward, impacting the telescopic shaft of the intermediate lifting mechanism 524 and the cutting die 522 on it, causing the strip 1 to be punched (see...). Figure 5 );

[0088] Third, the pressing telescopic power source 5321 extends downwards, and the loading telescopic power source 5311 extends upwards, causing the pressing plate 5322 and the support plate 5312 to clamp the punched fine mesh fabric from above and below (see...). Figure 6 );

[0089] Fourth, the intermediate lifting mechanism 524 retracts, and the loading telescopic power source 5311 continues to extend upward, pushing the pressure plate 5322 and the pressing telescopic power source 5321 back, pushing the fine mesh into the punching hole of the cutting die 522 (see...). Figure 7 );

[0090] Based on the flexibility of the fine mesh fabric itself, and the fact that the outer diameters of the pressure plate 5322 and the support plate 5312 are both smaller than the inner diameter of the cutting mold 522, the fine mesh fabric protrudes from the edge of the pressure plate 5322. When it moves upwards while being sandwiched between the two sides and tightly against the side wall of the punching hole, it forms a downward bending deformation of the edge. After the support plate 5312 retracts, the fine mesh fabric forms an upward arch with a certain elasticity and is naturally stuck in the punching hole.

[0091] 5. The retractable power source 5311 retracts, the intermediate lifting mechanism 524 retracts, driving the entire cutting mold 522 upward (see...). Figure 8 ).

[0092] This cycle allows for the punching, shearing, and gripping of the flexible fine-mesh mesh. If it is necessary to further transfer the cut fine-mesh mesh to the lower station, the feeding mechanism 540 continues to operate, as follows:

[0093] First, the moving drive source 542 drives the cutting mold 522 to move to the required station via the moving mounting plate 541 (see 9);

[0094] 2. The telescopic shaft of the intermediate lifting mechanism 524 extends downward to send the cutting mold 522 above the structure where the fine mesh sheet needs to be installed and to press it firmly against it (see...). Figure 10 );

[0095] 3. The pressing and telescopic power source 5321 extends downward to push out the fine-mesh mesh sheet and press it into the target position (see...). Figure 11 ).

[0096] Please see Figure 12 In another preferred embodiment, the hot melt head 610 is an annular head, and an elastic telescopic clamping member 620 is provided in the inner cavity of the hot melt head 610, with the end of the elastic telescopic clamping member 620 extending from the bottom end of the hot melt head 610.

[0097] When in use, as the hot melt head 610 descends, the bracket, large-hole steel mesh and fine-hole mesh can be pre-pressed by the elastic telescopic clamping member 620, thereby ensuring that the positions of the bracket, large-hole steel mesh and fine-hole mesh do not change during the hot pressing process of the hot melt head 610.

[0098] The aforementioned hair dryer filter assembly equipment can not only process fine-mesh mesh sheets, but also conveniently and quickly assemble the tail filter of the hair dryer, thereby improving the overall production efficiency of the product.
