Description

TECHNICAL FIELD

[0002] The non-woven fabric in the form of a roll material can be used as raw material for dry wipes, in-vitro diagnostic test papers, etc. and can be processed and produced through operation processes such as spraying, punching, drying, cutting, and subsequent detection according to actual processing process requirements to obtain corresponding finished products. There is no full-automatic equipment for non-woven fabric processing in the prior art, and most of the existing equipment is scattered and independent, which needs manual intervention for feeding, transferring, and other operations. The overall occupied area is large, the production efficiency is low, the degree of automation is low, and there are many actual problems affecting production in each independent equipment.

[0003] In the prior art, the unwinding action of the roll material is usually driven by a motor. Since the motor speed is set constant, the diameter of the roll material gradually decreases as unwinding proceeds, which shows a trend of actual unwinding slowing down. Moreover, the amount of the roll material as raw material is also unstable, so that the actual speed of unwinding is difficult to effectively and constantly control in the length direction. If a full-automatic equipment for non-woven fabric processing is to be formed by integrating the processing process requirements, the unwinding action and the intermittence of cutting must be matched, and the integrity of the non-woven fabric must be effectively guaranteed without causing excessive pulling and affecting the performance.

[0004] In the cutting mechanism for cutting the material belt, the cutter is usually fixed and installed in the cutter seat by means of bolt fastening or the like to form a hard connection, and the cutter seat is rotatably installed on the external translation mechanism by bearings. In the existing cutting mechanism, the concentricity requirement of the cutter relative to the bearing rotation cannot be effectively guaranteed due to the existence of processing errors, assembly errors, and other factors, and the cutter has a certain runout or even vibration during cutting. With the cutting proceeding, the cutter is prone to deviate from the preset cutting position due to wear, causing poor cutting, and the cutter is also prone to damage or even breakage due to the impact of vibration and collision with the track.

DETAILED DESCRIPTION

[0036] The specific embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0037] As Figure 1As shown, the non-woven fabric automatic processing equipment of the embodiment comprises a supporting platform one 30, the supporting platform one 30 carries the material belt 100 conveyed along the X direction, one end of the supporting platform one 30 is connected with the automatic unwinding mechanism 1 through the discharging temporary storage assembly 2, the other end of the supporting platform one 30 is connected to the mould pressing mechanism 50 through the clamping feeding mechanism 3 and the cutting mechanism 4, the clamping feeding mechanism 3 clamps the material belt 100 on the supporting platform one 30 to intermittently and orderly feed towards the mould pressing mechanism 50, the cutting mechanism 4 cuts the material belt 100 into material strips 200 along the width direction in cooperation with the feeding intermittence; the supporting platform two 20 is connected to the Y direction outer side of the mould pressing mechanism 50 through the track 51, the supporting platform two 20 is provided with the fork mechanism 8 along the two side edges in the X direction, the carrying mechanism 5, the visual detection assembly 9 and the marking verification assembly 6 are sequentially arranged above the supporting platform two 20 along the Y direction and along the X direction of the supporting platform two 20, the carrying mechanism 5 moves the material strip 200 from the mould pressing mechanism 50 to the supporting platform two 20 through the track 51.

[0038] In the embodiment, the supporting platform one 30 and the supporting platform two 20 are arranged in the Y direction, the supporting platform one 30 is connected between the automatic unwinding mechanism 1 and the cutting mechanism 4 and the mould pressing mechanism 50 along the X direction, and the visual detection assembly 9 and the marking verification assembly 6 are sequentially arranged on the supporting platform two 20, so that the automatic non-woven fabric processing equipment is rationally, effectively and compactly arranged, has high integration and occupies small space.

[0039] In the embodiment, the discharging temporary storage assembly 2 is arranged between the automatic unwinding mechanism 1 and the cutting mechanism 4, so that the rhythm between the automatic unwinding and the cutting can be effectively coordinated, the automatic unwinding can meet the rhythm of the subsequent cutting and mould pressing, is not affected by the rotating speed of the material roll 300 or the diameter size of the material on the material roll 300, and can effectively reduce or even avoid the pulling of the material belt 100, thereby helping to ensure the integrity of the material belt 100.

[0040] As shown, Figure 2 The automatic unwinding mechanism 1 is arranged below the supporting platform one 30, and the automatic unwinding mechanism 1 drives the material roll 300 to actively unwind the material belt 100.

[0041] The automatic unwinding mechanism 1 comprises the air expansion shaft 13 sleeved with the material roll 300, the end of the air expansion shaft 13 is installed on the translation seat of the axial translation assembly 12, the translation seat is driven by the driving power to move in the width direction of the material belt 100, and the motor assembly 11 driving the air expansion shaft 13 to actively rotate and unwind is installed on the translation seat.

[0042] In the embodiment, the material roll 300 can be adjusted in the width direction according to actual use requirements, such as the installation of different width material rolls 300, so that the unwound material belt 100 matches the subsequent operation.

[0043] In this embodiment, the axial translation component 12 can be composed of conventional cylinders, hydraulic cylinders, electric cylinders, etc., with linear output power matched with guide mechanisms such as slide rails, so as to realize and satisfy the adjustment of the material roll 300 in the width direction.

[0044] The support platform 30 is provided with guide width adjustment components 33 on both sides. The width limiting block in the guide width adjustment component 33 is close to the edge of the material strip 100, so that the guide width adjustment component 33 can push and adjust the position of the material strip 100 in the width direction to effectively align and match the subsequent process.

[0045] In this embodiment, the width limiting block can be moved in the width direction of the strip 100 by being pushed by a screw or other shaft-like component, thereby adjusting the spacing and position between the width limiting blocks on both sides.

[0046] like Figure 3 As shown, the discharge temporary storage assembly 2 includes a guide roller 21 located at the discharge point of the material roll 300, a guide roller 25 located above the guide roller 21, a swing roller 24 parallel to the side of the guide roller 25, and a guide roller 26 located at the end of the support platform 30. The swing roller 24 swings axially parallel to the width direction of the material strip 100. It also includes position sensors 23 corresponding to the two extreme positions in the swing direction of the swing roller 24.

[0047] The strip 100 unwound from the roll 300 passes under the guide roller 21 located below, then passes under the guide roller 25 located above, passes under the swing roller 24, and then passes under the guide roller 26 before being conveyed to the support platform 30. This ensures that the strip 100 has sufficient space to move around at the discharge temporary storage assembly 2.

[0048] In the material discharge temporary storage component 2 of this embodiment, the position sensor 23 located at the swing limit position monitors the position of the swing roller 24 in real time. When the swing roller 24 swings to the limit position, it triggers the automatic unwinding mechanism 1 to perform a pause or continue operation of active unwinding, thereby effectively maintaining a certain amount of material strip 100 between the automatic unwinding mechanism 1 and the clamping and feeding mechanism 3, satisfying the continuous and stable intermittent feeding of the clamping and feeding mechanism 3, and realizing the coordination and balance between the active unwinding of the automatic unwinding mechanism 1 and the intermittent orderly conveying.

[0049] In actual use, the oscillating roller 24 will oscillate under the action of the material strip 100. If the tension of the material strip 100 around the oscillating roller 24 is large, the material strip 100 will drive the oscillating roller 24 to oscillate along the conveying direction, such as swinging upwards, until it is sensed by the position sensor 23 at the corresponding extreme position. Then the automatic unwinding mechanism 1 will actively start unwinding. As the unwinding action proceeds, the material strip 100 wrapped around the oscillating roller 24 will gradually become relatively loose, and the oscillating roller 24 will oscillate in the opposite direction until it is sensed by the position sensor 23 at the corresponding other extreme position. Then the automatic unwinding mechanism 1 will stop actively unwinding. In the normal production process, the clamping and feeding mechanism 3 intermittently clamps the material strip 100 and conveys it toward the molding mechanism 50 according to its own cycle time.

[0050] In this embodiment, the two ends of the swing roller 24 are mounted below the support platform 30 via the swing frame 22. For example, the upper end of the swing frame 22 is rotatably mounted on the base plate 10, and the support platform 30 is supported above the base plate 10. The swing axis of the swing roller 24 is formed by the rotational mounting axis of the swing frame 22.

[0051] In one embodiment, the swing frame 22 can be an L-shaped structure with the opening facing upward. One end of the L-shaped structure forms the rotation axis, and the other end of the L-shaped structure is equipped with a swing roller 24, thereby effectively lowering the center of gravity of the swing frame 22 and ensuring the tension of the swing roller 24 on the material belt 100.

[0052] like Figure 4 As shown, the clamping and feeding mechanism 3 includes a clamping moving seat 303 that is driven by a driving power and guided by a guide rail assembly 304 to move along the conveying direction of the material belt 100. The clamping moving seat 303 extends upward at both ends and is clamped on both sides of the support platform 30. A clamping finger cylinder 301 is installed at each end of the clamping moving seat 303. A clamping claw 302 is installed at the output end of the clamping finger cylinder 301 that is arranged facing each other. The clamping claw 302 is symmetrically clamped at both sides of the material belt 100 in the width direction. Grooves are opened on both sides of the support platform 30 for the clamping claw 302 to accommodate and move, which facilitates the clamping claw 302 to clamp and move the material belt 100 synchronously.

[0053] In this embodiment, the gripper 302 has two positions, front and rear, relative to the support platform 30 in the X direction, and the gripper 302 reciprocates between the two positions. During feeding, the gripper 302 is located in the rear position relative to the support platform 30, and the gripper 302 clamps the material belt 100. The driving power works to drive the clamping moving seat 303 to move forward relative to the support platform 30, and the gripper 302 clamps the material belt 100 and moves forward. When the gripper 302 moves to the front position, the gripper 302 releases the material belt 100, completing one conveying of the material belt 100.

[0054] A check valve assembly 31 is provided on the support platform 30 located at the discharge end of the discharge temporary storage assembly 2, and the cam in the check valve assembly 31 is attached to the top surface of the material belt 100.

[0055] In this embodiment, the setting of the check valve component 31 effectively ensures that the material belt 100 is transported in an orderly manner in one direction on the support platform 30, which helps to ensure the reliability of intermittent feeding by the clamping and feeding mechanism 3.

[0056] In this embodiment, the cam is an eccentric wheel, which is rotatably arranged above the support platform 30. The bottom surface of the cam is in contact with the top surface of the material belt 100 to form a contact point. The distance between the cam wall surface in front of the contact point and the rotation axis is greater than the distance between the cam wall surface behind the contact point and the rotation axis. Thus, the cam can adaptively swing forward as the material belt 100 is normally conveyed forward. However, when the material belt 100 stops conveying or even tends to retreat, the cam is in contact with the material belt 100 at the contact point but cannot swing backward with the eccentric as the center. The cam is pressed against the material belt 100 to achieve the stop.

[0057] In this embodiment, the cam can be a circular outer wall surface, and the rotating center is offset to form an eccentric wheel.

[0058] In this embodiment, a rear pressure plate assembly 32 can be arranged between the check valve assembly 31 and the clamping and feeding mechanism 3. Equipment corresponding to processes such as spraying can be arranged between the rear pressure plate assembly 32 and the clamping and feeding mechanism 3. After the material belt 100 is conveyed to the support platform 30, the rear pressure plate assembly 32 presses the material belt 100 to ensure that the material belt 100 is fixed relative to the support platform 30, and the spraying work begins. After the spraying is completed, the rear pressure plate assembly 32 releases the pressure on the material belt 100, and the clamping and feeding mechanism 3 conveys the material belt 100 forward a preset distance.

[0059] like Figure 5 and Figure 6 As shown, a front pressure plate assembly 34 is arranged on the support platform 30 close to the cutting mechanism 4. The pressure plate 343 in the front pressure plate assembly 34 applies force to the top surface of the material strip 100 through the pressure edge 3431, which is close to the cutting edge of the blade 45 in the cutting mechanism 4. Combined with the pressure of the front pressure plate assembly 34 on the material strip 100, the blade 45 cuts the material strip 100 along the width direction. After cutting, the clamping and feeding mechanism 3 drives the material strip 100 forward a preset distance.

[0060] In one embodiment, the front pressure plate assembly 34 and the rear pressure plate assembly 32 have the same structure, for example... Figure 7As shown, pins 342 are coaxially mounted on the rear ends of both sides of the pressure plate 343. These pins 342 are rotatably mounted on the support 341, forming the pivot axis of the pressure plate 343. A downward driving power source 345 is rotatably mounted on the front side of the support 341 via lugs 346. The output end of the downward driving power source 345 is rotatably fitted to the pressure plate 343 via a second pin 344, which is located in front of the first pin 342. The downward driving power source 345 can be a commonly used linear power source such as a pneumatic cylinder, hydraulic cylinder, or electric cylinder.

[0061] In actual use, the downward driving force 345 works, pulling the pressure plate 343 to swing downward around the pin 342 until the front edge 3431 of the pressure plate 343 contacts and presses down on the material strip 100, thus achieving the pressing of the pressure plate 343 on the material strip 100; the downward driving force 345 reverses its action, pushing the pressure plate 343 to swing upward around the pin 342, causing the front edge 3431 of the pressure plate 343 to disengage from the material strip 100, thus releasing the pressing of the pressure plate 343 on the material strip 100.

[0062] like Figure 8 and Figure 9 As shown, the cutting mechanism 4 includes a cutter holder 46 that is driven by a linear module 43 to move along the width direction of the material belt 100. The cutter holder 46 is axially arranged along the conveying direction of the material belt 100. A ring-shaped blade 45 is coaxially mounted on the cutter holder 46. A ring spring 48 is sleeved on the cutter holder 46 on the side of the blade 45 away from the support platform 30. The ring spring 48 is limited and pressed against the side of the blade 45 by the press-fitting component 47. The ring spring 48 causes the blade 45 to press against the support platform 30.

[0063] In this embodiment, the cutting mechanism 4 uses a ring spring 48 to achieve elastic buffering installation of the blade 45 on the blade holder 46, which can effectively ensure that the blade 45 is close to the support platform 30 and will not leave the preset cutting position, and effectively reduce or even avoid the generation of vibration, ensuring smooth and efficient cutting, and helping to improve the service life of the blade 45.

[0064] In one embodiment, the press-fitting component 47 is pressed against the annular spring 48 via the conical surface 471, allowing the annular spring 48 to provide a certain elastic deformation space in the axial and radial directions of the blade 45. This effectively ensures the reliability and stability of the elastic buffer applied to the blade 45 by the annular spring 48, and guarantees the structural reliability of the cutting mechanism 4 during the cutting process. The press-fitting component 47 is screw-mounted on the blade holder 46, allowing the press-fitting component 47 to elastically press and adjust the blade 45 via the annular spring 48.

[0065] In one embodiment, the annular spring 48 is an annular structure formed by connecting the two cylindrical ends of a cylindrical spring end to end, such as... Figure 10As shown, this effectively ensures that the annular spring 48 has elasticity in both the axial and radial directions of the annulus, and effectively and reliably ensures that the annular spring 48 provides elastic buffering for the blade 45.

[0066] In this embodiment, a stop 451 is provided on the side of the blade 45 facing away from the annular spring 48. The stop 451 is embedded in the circumference of the tool holder 46, and the stop 451 restricts the blade 45 from disengaging from the tool holder 46 in the axial direction. The stop 451 can be a commonly used annular retaining ring structure, which is circumferentially engaged in the groove of the tool holder 46 to limit the blade 45 and ensure the installation of the blade 45 on the tool holder 46.

[0067] exist Figure 8 and Figure 9 In the illustrated embodiment, the cutter holder 46 is rotatably mounted on the translation seat 44 via bearing 461. The translation seat 44 is mounted on the output section of the linear module 1 43. The linear module 1 43 is supported above the width direction of the strip 100 by two side pillars 41. The operation of the linear module 1 43 drives the translation seat 44 to move in the width direction of the strip 100, thereby driving the blade 45 to move in the width direction of the strip 100 via the cutter holder 46. The rotational fit between the cutter holder 46 and the translation seat 44 enables the circumferential cutting edge of the blade 45 to cut the strip 100. A guide assembly 42 can be provided parallel to the linear module 1 43, with the translation seat 44 slidably fitted to the guide assembly 42, which provides guidance for the movement of the translation seat 44.

[0068] The support platform 30 is equipped with a cutting guide block 3001 at one end for the blade 45 to engage with. In actual operation, the pressure ridge 3431 of the pressure plate 343 in the front pressure plate assembly 34 presses against the strip 100 on the top surface of the cutting guide block 3001, and the cutting edge of the blade 45 engages with the side of the cutting guide block 3001. The cutting guide block 3001 can be made of wear-resistant material to ensure and improve the cutting effect and service life.

[0069] In this embodiment, the molding support 501 in the molding mechanism 50 is spaced apart at the front end of the support platform 30, and the spacing between them forms a space for the cutting movement of the blade 45. The upper part of the side of the molding support 501 facing the support platform 30 can be set as an inclined surface to facilitate the stable and reliable movement and conveying of the strip 100 toward the molding support 501 after cutting. The molding mechanism 50 in this embodiment can be a conventional equipment corresponding to conventional processes such as molding and punching.

[0070] like Figure 11 and Figure 12As shown, the conveying mechanism 5 includes a conveying seat 52 driven by a linear module to move along the Y direction. The conveying seat 52 facing the end of the material strip 200 has two gripping cylinders 53 installed at intervals in front and behind. The two grippers 54 in a single gripping cylinder 53 are arranged vertically to form a clamping structure. The grippers 54 in the two sets of gripping cylinders 53 clamp the same end of the material strip 200.

[0071] In this embodiment, since the material strip 200 is made of a thin and flexible material, two sets of grippers 54 are cleverly designed to simultaneously clamp the ends of the material strip 200 in the direction of movement. By clamping one end of the material strip 200 with the grippers 54, and in combination with the operation of the linear module, the material strip 200 is transported along the track 51 to the support platform 20, which effectively ensures the stability and reliability of the transport and avoids material slippage during transport.

[0072] like Figure 13 and Figure 14 As shown, short vertical plates 202 and long vertical plates 201 are installed at intervals on the support platform 20 located below the conveying mechanism 5, forming an extension section that is connected to the track 51 and located in the same straight direction. The conveying mechanism 5 transfers the material strip 200 to the extension section. The long vertical plate 201 blocks one side of the material strip 200, and the bottom end of the short vertical plate 202 is provided with a transverse groove 205 for the material strip 200 to move towards the other side, which effectively ensures that the material strip 200 transported to the extension section can move forward smoothly along the support platform 20.

[0073] In this embodiment, during the transfer and handling of the material strip 200 by the handling mechanism 5, the material strip 200 is supported and guided by the track 51 and the extension section which are connected in the same straight direction, effectively ensuring that the material strip 200 can be located in a preset position when it is transferred to the support platform 20.

[0074] According to actual needs, a baffle can also be set at the end of the extension section away from the track 51. When the conveying mechanism 5 clamps the material bar 200 and moves it to the support platform 20 via the track 51 and the extension section, the baffle can limit the material bar 200 at the end of the movement.

[0075] like Figure 15As shown, the shift fork mechanism 8 includes a translational force 82 arranged below the support platform 20. The translational force 82 is supported by the support 1 81. The output part of the translational force 82 is equipped with a vertical power 83. The output part of the vertical power 83 facing upward is equipped with a shift fork seat 84. The shift fork seat 84 supports two sets of U-shaped forks 87 arranged at intervals along the Y direction. Each set includes multiple U-shaped forks 87 arranged at intervals along the X direction. The corresponding U-shaped forks 87 in the two sets are arranged in pairs and pass through the support platform 20 from bottom to top and are clamped on both sides of the corresponding material strip 200. The support platform 20 is provided with a long groove 203 for the U-shaped forks 87 to pass upward and move forward. The setting of the long groove 203 ensures the upward passage of the U-shaped forks 87 and limits and guides the movement of the U-shaped forks 87.

[0076] In this embodiment, the translational force 82 provides forward or backward movement power to the U-shaped fork 87, thereby enabling the U-shaped fork 87 to push the material bar 200 forward or move backward to reset. The distance that the translational force 82 drives the fork seat 84 to move is a preset step distance for the U-shaped fork 87 to push the material bar 200 forward. The vertical force 83 provides upward or downward movement power to the U-shaped fork 87, thereby enabling the U-shaped fork 87 to clamp upward on both sides of the material bar 200 or detach downward from the material bar 200.

[0077] In this embodiment, longitudinal beams 85 are installed on the top surface of the shift fork seat 84 at intervals on the left and right. Multiple crossbeams 86 are embedded on the top surface of the longitudinal beams 85 at intervals along the front-back direction. U-shaped forks 87 with openings facing upwards are symmetrically installed at both ends of each crossbeam 86. The inner spacing of each U-shaped fork 87 is adapted to the size of a single material strip 200.

[0078] In this embodiment, the long groove 203 extends backward to the rear of the long vertical plate 201, thereby allowing the U-shaped fork 87 to move backward along the long groove 203 to the rear of the long vertical plate 201, thus effectively moving the material strip 200 at the extension section; the setting of the vertical groove 204 on the short vertical plate 202 and the long vertical plate 201 effectively ensures that the U-shaped fork 87 moves smoothly along the long groove 203, so that the material strip 200 can be smoothly moved forward from the extension section.

[0079] In one embodiment, a pressing member 88 may also be provided at the edge of the support platform 20 at the shift fork mechanism 8, and the pressing member 88 presses down at the edge of each material bar 200.

[0080] In this embodiment, the pressing member 88 can press down on the material strip 200 after it has been moved into place to ensure the smooth progress of detection and marking. The pressing member 88 can also limit the material strip 200 from above during the process of moving the material strip 200, which helps to ensure the stability and consistency of the material strip 200 being moved.

[0081] exist Figure 16In the illustrated embodiment, the pressing member 88 can be connected to the upper part of the support rod by inverted L-shaped members arranged at intervals, and the support rod is installed at the upward-facing output end of the pressing power 89; so that the pressing member 88 is located exactly at the left and right edges of the material bar 200 on the support platform 20. According to actual needs, the rear end of the bottom surface of the pressing member 88 can be set as an inclined surface 881, which facilitates the material bar 200 to be smoothly guided and moved forward from the extension section of the track 51 to the underside of the pressing member 88 via the inclined surface 881.

[0082] The visual inspection component 9 and the marking verification component 6 are respectively supported and arranged on the front and rear sides of the back plate 60. The back plate 60 is supported horizontally above the support platform 20 by the support column, which effectively simplifies the structure and makes the overall layout reasonable and compact.

[0083] exist Figure 13 In the embodiment shown, the vision inspection component 9 includes a linear module 3 91 installed on the rear side of the back plate 60. A vision component 92 is installed on the output part of the linear module 3 91. The image-taking end of the vision component 92 faces downward and is directly facing the material strip 200 on the support platform 2 20 below. The vision component 92 captures an image of the material strip 200.

[0084] In actual operation, the vision component 92 can be used to inspect the coating quality of the material strip 200. For example, according to the existing general inspection method, the image is captured and compared with the standard image to detect the coating width, coating color, etc.

[0085] like Figure 17 As shown, the structure of the marking verification component 6 is as follows: it includes a linear module 61 installed on the side of the back plate 60, an inkjet component 62 installed on the output part of the linear module 61, and a photoelectric sensor 63 installed on the side of the inkjet component 62. The photoelectric sensor 63 moves synchronously with the inkjet component 62 to detect the inkjet position.

[0086] In practical use, based on the detection feedback from the vision inspection component 9, the linear module 61 drives the inkjet component 62 to move upward on the support platform 20Y. The inkjet component 62 then sprays ink dots downwards at the material strip 200NG position for marking. Simultaneously, the photoelectric sensor 63 detects the presence or absence of ink dots. The inkjet component 62 can use existing standard spray guns, such as single-channel or dual-channel inkjet guns, as long as they can mark ink dots on the material strip 200 below.

[0087] In this embodiment, a waste liquid tank 64 can also be provided below the inkjet assembly 62, so that waste liquid can be collected in the waste liquid tank 64 when cleaning the inkjet assembly 62 for maintenance or other purposes.

[0088] In one embodiment, a support platform 40 may be provided outside the conveying tail end of the support platform 20, which is moved and supported between the support platform 20 and the support platform 40 by the transfer mechanism 7.

[0089] exist Figure 18 In the embodiment shown, the transfer mechanism 7 includes a translation drive 71 installed below the support platform 20, a lifting drive 72 installed at the output end of the translation drive 71, and a support platform 73 installed at the upward output end of the lifting drive 72. Thus, the operation of the translation drive 71 drives the support platform 73 to move in the front-back direction between the support platform 20 and the support platform 40, and the operation of the lifting drive 72 drives the support platform 73 to move in the vertical direction, so that the support platform 73 receives the material strip 200 from the support platform 20 and places the material strip 200 onto the support platform 40.

[0090] The front end face of the second support platform 20 is provided with a recess in the middle for the support platform 73 to accommodate the material strip 200. The support platform 73 receives the material strip 200 from the second support platform 20 through the recess. The opposite ends of the support platform 73 and the support platform 40 are respectively provided with matching convex and concave structures, so as to effectively realize the smooth and reliable transfer of the material strip 200 from the second support platform 20 to the support platform 73 and from the support platform 73 to the support platform 40. The top surface of the support platform 73 is provided with an adsorption hole that communicates with an external air source. During the process of the support platform 73 bearing and transferring the material strip 200, the adsorption effect can be used to ensure the stability of the material strip 200 on the support platform 73.

[0091] This embodiment of a nonwoven fabric automated processing equipment includes the following steps: The automatic unwinding mechanism 1 actively unwinds the material strip 100. The preset amount of material strip 100 is temporarily stored at the discharge temporary storage component 2. The discharge temporary storage component 2 and the automatic unwinding mechanism 1 work together to ensure the intermittent continuous feeding of the clamping and feeding mechanism 3.

[0092] Specifically, the motor assembly 11 in the automatic unwinding mechanism 1 operates to unwind the strip 100 from the roll 300. The strip 100 is sequentially transported to the support platform 30 after passing through guide roller 1 21, guide roller 25, swing roller 24, and guide roller 3 26. When the strip 100 at the swing roller 24 is relatively loose, the swing roller 24 will swing down until it reaches the corresponding position sensor 23, at which point the motor assembly 11 stops working. With the intermittent feeding of the clamping and feeding mechanism 3, the strip 100 at the swing roller 24 gradually tightens, causing the swing roller 24 to swing up until it reaches the corresponding position sensor 23, at which point the motor assembly 11 operates again, realizing intermittent automatic active unwinding.

[0093] The material strip 100 is intermittently clamped by the clamping and feeding mechanism 3 and fed towards the molding mechanism 50. The cutting mechanism 4 cuts the material strip 100 into strips 200 along the width direction at the feeding end of the molding mechanism 50.

[0094] Specifically: In the clamping and feeding mechanism 3, the clamp 302 is located behind the support platform 30. The clamp 302 clamps the material strip 100 and moves forward relative to the support platform 30. When the clamp 302 moves to the front position, the clamp 302 releases the material strip 100, completing one conveying of the material strip 100. The material strip 100 is conveyed to the molding mechanism 50, and then the cutting mechanism 4 cuts the material strip 100 at the feeding end of the molding mechanism 50.

[0095] The molding mechanism 50 performs molding operation on the material strip 200. The conveying mechanism 5 transfers the molded material strip 200 to the support platform 20 via the track 51. The shift fork mechanism 8 drives the material strip 200 to move intermittently and continuously along the support platform 20 for a preset distance. The visual inspection component 9 and the marking and verification component 6 sequentially inspect, mark and verify the material strip 200.

[0096] This invention achieves a reasonable, effective, and compact layout for fully automated nonwoven fabric processing equipment, with high integration and small footprint. Furthermore, the fully automated production process greatly helps to improve production efficiency and reduce labor costs.
