Description

Technical Field

[0001] The present invention relates to the field of composite devices, and particularly to a composite device with multi-state switching of a dispensing head and a composite method for an antibacterial composite fabric. Background Art

[0002] The working principle of a fabric composite device is mainly based on the action of an adhesive. During the composite process, first, a leveling component ensures the flatness of the fabric, and then a cleaning component removes impurities on the fabric surface. Next, the fabric is fed into the composite area through a feeding component. Here, a composite roller coated with the adhesive evenly applies the adhesive on the fabric. Subsequently, the fabric is pressed by a pressure roller to achieve a firm bond between different fabrics. Finally, the composite fabric is wound up by a winding mechanism to complete the composite process.

[0003] Dot gluing is a gluing technique used in the fabric composite process. It evenly distributes the adhesive on the fabric surface in the form of dots through a specific gluing device. The purpose of this gluing method is to achieve the bonding between fabrics only at specific points or with the minimum amount of adhesive used during composite, thereby achieving effects such as material saving, weight reduction of the composite fabric, improvement of breathability and handfeel.

[0004] Chinese Patent Application CN111873598A discloses a special composite fabric and its production equipment, including a workbench. A feeding component is provided at one end of the workbench, and a transfer roller is provided at the top of the workbench. Support legs are provided at the bottom of the workbench. A gluing component is provided at one end of the transfer roller close to the feeding component, and a first pressing component is provided at the other end of the transfer roller away from the gluing component. By providing a second electric push rod, a connecting frame, a second rolling roller, and a second fixing frame, when the composite fabric moves below the second pressing component, the second electric push rod is controlled to operate, so that it drives the four second rolling rollers to move back and forth horizontally on the composite fabric through the connecting frame. While moving, the four second rolling rollers rotate through the second fixing frame, thereby performing secondary pressing on the composite fabric, making the pressing of the composite fabric more uniform and effectively solving the problem of uneven fabric pressing;

[0005] Chinese patent application CN111572166A discloses a multi-layer composite sofa fabric gluing mechanism, comprising a mounting frame, two introduction rollers and two guide rollers, a scraping glue groove is provided in the middle of the mounting frame, a roller glue roller is rotatably arranged in the scraping glue groove, a first scraper and a second scraper are arranged at intervals and staggered at both ends of the roller glue roller in the scraping glue groove, the first scraper and the second scraper are fitted to the surface of the roller glue roller, and the first scraper and the second scraper are arranged close to the fabric to be coated; a glue baffle is provided at the fabric glue roller coating part of the roller glue roller at the interval between the first scraper and the second scraper; a winding groove is provided below the first scraper and the second scraper; the fabric entrance of the mounting frame is hollow, and a glue adding groove is also fixed at the fabric entrance end of the mounting frame, the glue adding groove is tilted downward and penetrates the mounting frame and is fitted with the glue adding groove, so that the opposite sides of the fabric to be composited can be glued at the same time, and the fabrics are glued evenly when they are fitted, and the firmness is high.

[0006] The above patents and prior art also have the following defects:

[0007] The prior art uses composite equipment for point-shaped gluing, and the density and spacing of the glue points cannot be adjusted. For different application scenarios of fabrics, when different bonding strengths are required, it is easy to cause the glue points to be too dense, affecting the softness of the fabric and increasing the cost of gluing. The glue roller needs to be replaced to adjust the density of the glue points, which is cumbersome to operate, with long downtime, and is time-consuming and labor-intensive.

[0030] In summary, the technical effects and advantages of the present invention are as follows:

Detailed implementation mode

[0044] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0045] Example 1: Refer to Figures 1-9The composite device shown includes a composite wheel 1, and an adhesive application assembly 2 is provided on one side of the composite wheel 1; the adhesive application assembly 2 includes a plurality of adhesive application units 21 and an adhesive application roller 22. The adhesive application roller 22 can drive the plurality of adhesive application units 21 to rotate. The plurality of adhesive application units 21 are divided into a first group, a second group, and a third group. The plurality of adhesive application units 21 in the first group are equidistantly arranged on the adhesive application roller 22. The plurality of adhesive application units 21 in the second group are arranged at the midpoints between two adjacent adhesive application units 21 in the first group. The plurality of adhesive application units 21 in the third group are arranged at the midpoints between an adjacent adhesive application unit 21 in the first group and an adhesive application unit 21 in the second group;

[0046] The adhesive application unit 21 includes a plurality of dispensing modules distributed circumferentially. The dispensing module includes a dispensing head 211. The adhesive application units 21 in the same group are commonly connected to an operation assembly 3. The operation assembly 3 can switch the dispensing heads 211 in the adhesive application units 21 in the same group between the extended state and the retracted state;

[0047] The adhesive application assembly 2 further includes a glue supply housing 23. The dispensing head 211 in the extended state can contact the composite glue in the glue supply housing 23 and transfer the composite glue to the fabric as it rotates.

[0048] The fabric is transported to the position of the adhesive application assembly 2. The adhesive application roller 22 rotates to drive the dispensing heads 211 in the adhesive application units 21 to rotate. The dispensing heads 211 rotate into the glue supply housing 23 and dip the glue in the glue supply housing 23. The dispensing heads 211 continue to rotate until they contact the fabric and transfer the glue to the fabric. When it is necessary to adjust the density and spacing of the dispensing heads 211 in the extended state on the adhesive application roller 22, operate the operation assembly 3 corresponding to the adhesive application units 21 in the third group. The operation assembly 3 switches all the dispensing heads 211 in the adhesive application units 21 in the third group to the retracted state. At this time, the spacing between adjacent dispensing heads 211 in the adhesive application units 21 in the first group and the second group is the same, and the spacing between the dispensing heads 211 in the extended state on the adhesive application roller 22 increases. When it is still necessary to adjust the density and spacing of the dispensing heads 211 on the adhesive application roller 22, operate the operation assembly 3 corresponding to the adhesive application units 21 in the second group. The operation assembly 3 switches all the dispensing heads 211 in the adhesive application units 21 in the third group to the retracted state. At this time, the spacing between adjacent dispensing heads 211 in the adhesive application units 21 in the first group is the same, and the spacing between the dispensing heads 211 in the extended state on the adhesive application roller 22 increases again. The dispensing heads 211 in the retracted state do not contact the glue in the glue supply housing 23, so as to adjust the density and spacing of the glue application points on the fabric. The glued fabric and the second fabric are transported to the composite wheel 1, and the composite wheel 1 composites the fabrics.

[0049] A number of gluing units 21 in the third group are arranged at the midpoints between adjacent gluing units 21 in the first and second groups. By operating the operating unit 32, the dispensing nozzles 211 in the gluing units 21 of the third group are switched to the retracted state, so that the gluing units 21 of the third group do not participate in dispensing on the fabric. Similarly, the gluing units 21 of the second group are operated as required, thereby adjusting the density and spacing of gluing on the fabric to adapt to different strengths of fabric lamination. It has stronger adaptability and simpler operation. When the dispensing nozzles 211 in the gluing units 21 of the third group are in the retracted state, the spacing between the dispensing nozzles 211 in the gluing units 21 of the first group is the same as that between the dispensing nozzles 211 in the gluing units 21 of the second group. When the dispensing nozzles 211 in the gluing units 21 of the second group are in the retracted state, the spacing between the dispensing nozzles 211 in the gluing units 21 of the first group is the same. It can uniformly reduce the dispensing density, increase the dispensing spacing, and at the same time make the spacing between the dispensing positions the same, increasing the strength uniformity after fabric lamination and improving the lamination quality.

[0050] Example two, refer to Figures 1-9 , the gluing unit 21 further includes a rotating shell 216, the rotating shell 216 is fixedly installed on the gluing roller 22, the dispensing module further includes a moving block 212 and a return spring 213, the moving block 212 is fixedly installed on the dispensing nozzle 211, the rotating shell 216 is provided with a dispensing hole corresponding to the dispensing nozzle 211, the dispensing nozzle 211 passes through the dispensing hole and is slidably matched with the rotating shell 216, one end of the return spring 213 is fixedly installed on the moving block 212, the other end of the return spring 213 is fixedly installed on the inner wall of the rotating shell 216, and the return spring 213 is sleeved on the dispensing nozzle 211.

[0051] When the moving block 212 moves towards the direction close to the dispensing nozzle 211, the moving block 212 drives the dispensing nozzle 211 to move out of the rotating shell 216 and compresses the return spring 213, and the dispensing nozzle 211 is in the extended state. When the moving block 212 moves towards the direction away from the dispensing nozzle 211, the moving block 212 drives the dispensing nozzle 211 to move into the rotating shell 216, and the dispensing nozzle 211 is in the retracted state.

[0052] The rotation of the gluing roller 22 drives the rotation of the rotating shell 216, and the rotating shell 216 drives the dispensing nozzle 211 to rotate. The dispensing nozzle 211 in the extended state dispenses glue on the fabric.

[0053] Sliding blocks are fixedly installed on both sides of the moving block 212, and sliding grooves are formed on the inner wall of the rotating shell 216. The sliding blocks are slidably matched in the sliding grooves, making the moving block 212 and the dispensing nozzle 211 more stable and not easy to shake.

[0054] Example three, refer to Figures 1-9, the gluing unit 21 further includes a rotating block 214, a rotating cylinder, and a rotating gear 215; the rotating block 214 is rotatably connected to the gluing roller 22, and a plurality of release grooves are formed in the rotating block 214. One side wall of the release groove is provided with an inclined surface, and the side wall of the moving block 212 is inclined. The rotating cylinder is fixedly installed on the rotating block 214, the rotating cylinder is rotatably connected to the gluing roller 22, the rotating cylinder penetrates through the rotating shell 216 and is rotatably connected to the rotating shell 216, and the rotating gear 215 is fixedly installed on the rotating cylinder.

[0055] The operating component 3 can drive the rotating gear 215 to rotate. The rotating gear 215 drives the rotating cylinder to rotate, and the rotating cylinder drives the rotating block 214 to rotate. When the dispensing head 211 is in the extended state, when driving the rotating block 214 to rotate, the release groove on the rotating block 214 rotates to the position of the moving block 212, and the return spring 213 pushes the moving block 212 to move into the release groove. The moving block 212 drives the dispensing head 211 to move into the rotating shell 216, and the dispensing head 211 switches to the retracted state. When the dispensing head 211 is in the retracted state and driving the rotating block 214 to rotate in the reverse direction, the rotating block 214 squeezes the inclined surface of the moving block 212 through the inclined surface of the release groove, causing the moving block 212 to be extruded and move out of the release groove. The moving block 212 drives the dispensing head 211 to move outside the rotating shell 216, and the dispensing head 211 switches to the extended state, enabling the dispensing head 211 to switch between the extended state and the retracted state.

[0056] Example 4, referring to Figures 1-9 , the operating component 3 includes a plurality of transmission units 31 and an operating unit 32. The plurality of transmission units 31 correspond to the gluing unit 21. The transmission unit 31 includes a transmission gear 311, a fixing plate 312, a driving side gear 313, and a driven side gear 314. The operating unit 32 can push the driving side gear 313 to move into engagement with the driven side gear 314. The operating unit 32 can drive the driving side gear 313 to rotate. The transmission gear 311 meshes with the rotating gear 215. The transmission gear 311 is fixedly installed on the fixing plate 312, and the driven side gear 314 is fixedly installed on the transmission gear 311.

[0057] The operating unit 32 drives the driving side gear 313 to move, so that the driving side gear 313 moves into engagement with the driven side gear 314. The operating unit 32 drives the driving side gear 313 to rotate. The driving side gear 313 drives the driven side gear 314 to rotate. The driven side gear 314 drives the transmission gear 311 to rotate. The transmission gear 311 drives the rotating gear 215 to rotate. The rotating gear 215 drives the rotating block 214 to rotate.

[0058] Example 5, referring to Figures 1-9, the operation unit 32 includes an operating lever 321, an operating block 322, an operating plate, and an operating spring 323. The operating plate is fixedly installed on the operating lever 321. One end of the operating spring 323 is fixedly installed on the operating plate. The driving-side gear 313 is fixedly installed on the operating lever 321. The operating block 322 is fixedly installed at the end of the operating lever 321. Anti-slip lines are provided on the operating block 322.

[0059] First, stop the rotation of the glue applicator roller 22 and lock it. First, push the operating lever 321 to move. The operating lever 321 squeezes the operating spring 323 and drives the driving-side gear 313 to move. The driving-side gear 313 moves to engage with the driven-side gear 314. Then, rotate the operating lever 321. The operating lever 321 drives the driving-side gear 313 to rotate. The driving-side gear 313 drives the driven-side gear 314 to rotate. The driven-side gear 314 drives the transmission gear 311 to rotate. The transmission gear 311 drives the rotating gear 215 to rotate. The rotating gear 215 drives the rotating block 214 to rotate. At this time, the glue applicator roller 22, the rotating housing 216, and the moving block 212 are locked and cannot move. A relative movement is generated between the rotating block 214 and the moving block 212, causing the moving block 212 to move and drive the dispensing head 211 to move. After the operation is completed, the operating spring 323 pushes the operating lever 321 to reset. The operating lever 321 drives the driving-side gear 313 to reset. The driving-side gear 313 disengages from the driven-side gear 314. The rotation of the glue applicator roller 22 drives the dispensing head 211, the rotating block 214, and the rotating gear 215. The rotating gear 215 drives the transmission gear 311 to rotate, and the transmission gear 311 will not drive the operating lever 321 to rotate, reducing the resistance. At the same time, the operating lever 321 will not rotate, preventing accidental injuries caused by the rotation of the operating lever 321 during the dispensing process.

[0060] A blocking block is also fixedly installed on the rotating block 214. When the dispensing head 211 is in the extended state, the moving block 212 abuts against the blocking block. The rotation of the glue applicator roller 22 drives the moving block 212 to rotate through the rotating housing 216. The moving block 212 abuts against the blocking block and drives the rotating block 214 to rotate, causing the moving block 212 and the rotating block 214 to rotate synchronously without relative displacement and without changing the state of the dispensing head 211. When the dispensing head 211 is in the retracted state, since the moving block 212 is located in the release groove, when the moving block 212 and the rotating block 214 have relative displacement, they need to overcome the elastic force of the return spring 213. Therefore, the moving block 212 and the rotating block 214 will not have relative displacement and will not change the state of the dispensing head 211.

[0061] Example Six, refer to Figures 1-9, the gluing assembly 2 further includes a fixed housing 24 and two fixed side plates 25. The fixed housing 24 is fixedly installed on the fixed side plates 25. The gluing roller 22 is rotatably connected to the fixed side plates 25. The fixing plate 312 is fixedly installed on the fixed housing 24. The glue supply housing 23 is fixedly installed on the fixed side plates 25. The operating rod 321 is slidably fitted on the fixed side plates 25. One end of the corresponding operating spring 323 is fixedly installed on the fixed side plates 25.

[0062] Example Seven, refer to Figures 1-9 , the glue supply housing 23 is located at the bottom of the gluing roller 22. The gluing assembly 2 further includes a glue supply pipe 26, a plurality of glue supply branch pipes 27 and a glue pump. The glue supply pipe 26 is fixedly installed on the fixed side plates 25. The plurality of glue supply branch pipes 27 are equidistantly fixedly installed on the glue supply housing 23 and communicate with the glue supply housing 23. The glue supply pipe 26 communicates with the glue pump.

[0063] The glue pump feeds the composite glue into the glue supply pipe 26. The composite glue in the glue supply pipe 26 enters the plurality of glue supply branch pipes 27 and flows into the rotating housing 216, making the supply of the composite glue in the rotating housing 216 more uniform.

[0064] Example Eight, refer to Figures 1-9 , the gluing assembly 2 further includes a gluing motor 28, a pressing roller 29 and a pressing motor 20. The gluing motor 28 is fixedly installed on the fixed side plates 25. The output end of the gluing roller 22 is fixedly installed on the gluing roller 22.
