Description

Technical Field

[0001] This invention relates to the field of protective clothing production equipment technology, specifically to an automatic sewing and sealing device for protective clothing and its usage method. Background Technology

[0002] Protective clothing is a specialized functional workwear made primarily of high-molecular polymer materials, non-woven fabrics, and breathable microporous membranes, through multi-layer composite and hot-press bonding processes. It aims to build a reliable physical barrier for the wearer, effectively resisting the harm to the human body from external harmful factors such as physical impact, chemical erosion, and biological infection. It is a core piece of equipment for ensuring the life safety and occupational health of workers.

[0003] In existing technologies, protective clothing seam sealing equipment mostly uses rigid clamping to fix the fabric, which not only easily scratches or deforms the fabric, but also makes it difficult to adapt to fabrics of different thicknesses. The spraying angle is fixed, and the adhesive cannot be accurately aligned with the seam gap, resulting in frequent problems such as missed spraying and uneven adhesive layer distribution. The equipment cannot automatically adapt to protective clothing of different sizes, relying on manual adjustment, which can easily cause unilateral stretching and deformation of the fabric during the adjustment process. The spray head position is not adjustable, making it difficult to cover special positions such as corner seams and irregular curved seams, often requiring manual re-applying of adhesive. The adhesive delivery pipeline lacks flexible compensation capabilities, and the pipeline is prone to bending, blockage, stretching, leakage, or even interruption of spraying when the spray head moves. The pressure in the sealing process is uncontrollable, and rigid crushing can easily damage the fabric or cause insufficient adhesive filling. In addition, the sealing and delivery are carried out in separate steps, resulting in poor process connection and seriously restricting the overall operation efficiency. Summary of the Invention

A first connecting member is fixedly connected to one side of the sleeve block, and an adjusting block is rotatably connected to the inner cavity of the first connecting member.

One end of the second threaded rod extends through to the top of the fixed block and is threadedly connected to a second threaded block. One side of the second threaded block is fixedly connected to the sleeve block.

[0009] Furthermore, as a preferred embodiment of the present invention, the second drive mechanism includes a second motor fixedly connected to the bottom of the square plate, the output shaft of the second motor being fixedly connected to a drive gear, and a driven gear being sleeved on the surface of the guide rod, the drive gear meshing with the driven gear.

[0010] Furthermore, as a preferred embodiment of the present invention, the circulation mechanism includes a water pump fixedly connected to the bottom of the water tank, the water pump having an inlet pipe connected to its inlet, one end of the inlet pipe extending into the inner cavity of the water tank, and the water pump having a flexible hose connected to its outlet, one end of the flexible hose being connected to the liquid inlet pipe.

[0011] Furthermore, as a preferred embodiment of the present invention, the extrusion mechanism includes a third fixed plate fixedly connected to the output shaft of the second cylinder. A baffle is provided on the top of the third fixed plate, and a second recess is provided on the bottom of the third fixed plate. A conveying roller is rotatably connected to the inner cavity of the second recess. Limiting rods are fixedly connected to both sides of the top of the second recess. One end of the limiting rod extends through to the top of the third fixed plate and is fixedly connected to the baffle. A second spring is sleeved on the surface of the limiting rod, and both ends of the second spring are fixedly connected to the third fixed plate and the second recess, respectively.

[0012] Furthermore, as a preferred embodiment of the present invention, a guide frame is fixedly connected to the bottom of the first fixing plate, a slider is slidably connected to the inner cavity of the guide frame, and one side of the slider is fixedly connected to the first threaded block.

[0013] Furthermore, as a preferred embodiment of the present invention, a limiting block is fixedly connected to one end of the second threaded rod, and the limiting block is circular in shape.

[0014] An automatic seam sealing and taping device for protective clothing, the method of using which includes the following steps: Step 1: Place the fabric to be sewn on top of the conveyor and the first fixing plate, stacking the edges of the two pieces of fabric. Then start the dual-axis motor. The output shaft of the dual-axis motor drives the first threaded rod to rotate. When the first threaded rod rotates, it drives the first threaded block to move. The first threaded block drives the support block to move. The support block drives the fixing mechanism to move, thus adjusting the position of the fixing mechanism according to the size of the fabric, thereby fixing fabrics of different specifications.

[0015] Step 2: When the placement plate moves above the fabric, activate the electric telescopic rod. The output end of the electric telescopic rod drives the extrusion plate downward, which in turn drives the short rod downward. The short rod then drives the slide plate to slide downward on the surface of the electric telescopic rod. As the extrusion plate moves, it stretches the first spring. When the extrusion plate moves downward, it causes the ball bearings at its bottom to come into contact with the fabric, thus fixing the fabric in place and preventing it from shifting after placement.

[0016] Step 3: Start the first cylinder. The output shaft of the first cylinder drives the second fixed plate to move downward. The second fixed plate drives the sewing head to move downward. When the sewing head moves to the designated position, start the sewing head to sew the two overlapping pieces of fabric together.

[0017] Step 4: While sewing, start the water pump. The water pump delivers the adhesive from the tank to the nozzle through the inlet pipe and telescopic hose. The adhesive is then sprayed onto the sewn fabric, effectively improving the tightness of the fabric connection. During adhesive spraying, the first motor is activated. The output shaft of the first motor drives the second threaded rod to rotate, which in turn moves the second threaded block. The second threaded block causes the sleeve to slide on the surface of the guide rod. As the sleeve moves, it moves the first connector, which in turn moves one end of the adjusting block upwards. The other end of the adjusting block moves the second connector, causing the nozzle to move in an arc around the first concave block. The nozzle then rotates the second protrusion within the concave block, thus adjusting the spray angle and ensuring more even adhesive application.

[0018] Step 5: Start the second motor. The output shaft of the second motor drives the drive gear to rotate, which in turn drives the driven gear to rotate. The driven gear drives the fixed block to rotate via the guide rod, and the fixed block drives the nozzle to rotate via the adjustment mechanism. This allows the spraying direction of the nozzle to be adjusted, increasing the spraying area.

[0019] Step Six: After the fabric is sewn and the adhesive is sprayed, start the conveying device to transport the fabric backward. When the fabric moves to the bottom of the extrusion mechanism, start the second cylinder. The output end of the second cylinder drives the third fixed plate to move downward. The third fixed plate drives the second concave block to move downward through the baffle and limit rod. The second concave block drives the conveying roller to move, so that the conveying roller contacts the fabric. Then start the conveying roller. The conveying roller rolls at the position where the adhesive is sprayed on the fabric, which effectively improves the adhesion of the adhesive and makes the fabric less likely to separate.

[0020] Beneficial effects: The technical solution of this application has the following technical effects: This invention has the advantages of flexible and stable positioning, no damage to the fabric, adjustable angle, and precise spraying. In actual use, the electric telescopic rod in the fixing mechanism drives the extrusion plate to press down, and with the elastic buffer of the first spring and the guide limit of the short rod and the slide plate, flexible and stable positioning of protective clothing fabrics of different thicknesses is achieved, avoiding damage to the fabric caused by rigid clamping; the dual-axis motor in the first drive mechanism synchronously drives the first threaded rods on both sides to rotate, driving the first threaded block and the support block to move synchronously, so that the fixing mechanism can quickly adapt to fabrics of different specifications and sizes. The dual-axis synchronous design effectively avoids unilateral stretching and deformation of the fabric during adjustment; the first motor in the adjustment mechanism drives the second threaded rod to drive the second threaded block to rise and fall along the guide rod, and then through the linkage transmission composed of the sleeve block, the first connecting piece, the adjustment block, and the second connecting piece, the spray head is positioned around the first concave block. The spray nozzle features an arc-shaped deflection at its center, allowing for flexible adjustment of the spraying angle based on the direction of the seam, ensuring precise alignment of the adhesive with the seam. In conjunction with the second motor in the second drive mechanism, the guide rod rotates circumferentially via the meshing of the drive and driven gears, enabling the nozzle to adjust its orientation. This allows for comprehensive spraying of special locations such as corner seams and irregularly shaped curved seams in protective clothing without moving the main sewing head. The water pump in the distribution mechanism delivers adhesive from the tank to the nozzle via a telescopic hose. The flexible hose's adaptability perfectly accommodates the nozzle's positional shifts during angle deflection and circumferential rotation, ensuring stable spraying pressure and preventing pipe blockage throughout the process. The extrusion mechanism uses a second cylinder to drive the conveyor roller downwards, guided by a limit rod and buffered by a second spring, to uniformly press and fill the seam gaps with constant, flexible pressure. The rolling motion of the conveyor roller also assists in the smooth feeding of the fabric, achieving synchronous connection between adhesive pressing and conveying.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. To better understand the technical content of the present invention, specific embodiments are provided and described in conjunction with the accompanying drawings. Various aspects of the present invention are described in this disclosure with reference to the accompanying drawings, which illustrate numerous illustrative embodiments. It should be understood that the various concepts and embodiments described above, as well as those described in more detail below, can be implemented in any of many ways. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0025] As attached Figure 1 To be continued Figure 6 As shown: This embodiment provides an automatic seam sealing and taping device for protective clothing, including a conveying device 1. First fixing plates 2 are fixedly connected to both sides of the conveying device 1. Two support legs 22 are fixedly connected to the bottom of the first fixing plates 2. A fixing mechanism 3 is provided on the top of the first fixing plates 2. A first driving mechanism 4 is provided at the bottom of the conveying device 1. A first cylinder 5 is fixedly connected to the top of the left side of the first fixing plate 2. A second fixing plate 6 is fixedly connected to the output end of the first cylinder 5. A sewing head 7 is fixedly connected to one side of the second fixing plate 6. The bottom of the second fixing plate 6 is fixedly connected to... A water tank 8 and a square plate 9 are fixedly connected. A guide rod 10 is rotatably connected to the bottom of the square plate 9. A fixing block 11 is fixedly connected to the bottom end of the guide rod 10. A nozzle 12 is provided on one side of the fixing block 11. An inlet pipe 13 is connected to the bottom of the nozzle 12. An adjustment mechanism 14 is slidably connected to the surface of the guide rod 10. A second drive mechanism 15 is fixedly connected to the bottom of the square plate 9. A flow mechanism 16 is provided at the bottom of the water tank 8. A second cylinder 17 is fixedly connected to the top of the first fixing plate 2 on the right side. A squeezing mechanism 18 is fixedly connected to the output end of the second cylinder 17.

[0026] Specifically, the fixing mechanism 3 includes a placement plate 31 disposed on the top of the first fixing plate 2, a pressing plate 32 disposed at the bottom of the placement plate 31, an electric telescopic rod 33 embedded in the top of the pressing plate 32, the output end of the electric telescopic rod 33 being fixedly connected to the pressing plate 32, a sliding plate 34 being slidably connected to the surface of the electric telescopic rod 33, a short rod 35 being fixedly connected to the top of the pressing plate 32, the top end of the short rod 35 penetrating to the top of the placement plate 31 and being fixedly connected to the sliding plate 34, a first spring 36 being sleeved on the surface of the short rod 35, and the two ends of the first spring 36 being fixedly connected to the placement plate 31 and the pressing plate 32 respectively.

[0027] In this embodiment: through the setting of the fixing mechanism 3, the electric telescopic rod 33 drives the extrusion plate 32 to press down. With the guiding and limiting effect of the short rod 35 and the sliding plate 34, the extrusion plate 32 remains horizontal and stable during the pressing process. At the same time, the first spring 36 provides elastic cushioning, which can not only adapt to protective clothing fabrics of different thicknesses, but also avoid rigid clamping from scratching the fabric surface. The bottom ball contact with the fabric can further reduce friction damage, so that the fabric is stable and does not shift during sewing and spraying, which greatly improves the positioning accuracy of sewing operations and fabric compatibility.

[0028] Specifically, the first drive mechanism 4 includes a dual-axis motor 41 fixedly connected to the bottom of the conveying device 1. Both output shafts of the dual-axis motor 41 are fixedly connected to a first threaded rod 42. The other end of the first threaded rod 42 is rotatably connected to a first protrusion 43. The top of the first protrusion 43 is fixedly connected to the first fixed plate 2. The surface of the first threaded rod 42 is threadedly connected to a first threaded block 44. One side of the first threaded block 44 is fixedly connected to a support block 45. One side of the support block 45 extends through to the top of the first fixed plate 2 and is fixedly connected to the placement plate 31.

[0029] In this embodiment: the first drive mechanism 4 uses a dual-axis motor 41 to synchronously drive two first threaded rods 42 to rotate. The first protrusion 43 provides stable rotational support for the threaded rods, driving the first threaded blocks 44 on both sides to move laterally synchronously. Then, through the support block 45, the fixing mechanism 3 is moved as a whole. It can quickly adapt to protective clothing fabrics of different specifications and sizes without manual adjustment. The dual-axis synchronous design ensures that the movement stroke on both sides is completely consistent, avoiding the problem of unilateral stretching and deformation of the fabric during the adjustment process. It significantly improves the equipment's compatibility and positioning efficiency for multiple models of protective clothing.

[0030] Specifically, the adjustment mechanism 14 includes a sleeve block 141 fitted onto the surface of the guide rod 10. A first connector 142 is fixedly connected to one side of the sleeve block 141. An adjustment block 143 is rotatably connected to the inner cavity of the first connector 142. A second connector 144 is rotatably connected to the other end of the adjustment block 143. The bottom of the second connector 144 is fixedly connected to the nozzle 12. A first recess 145 is fixedly connected to one side of the fixing block 11. A second protrusion 146 is rotatably connected to the inner cavity of the first recess 145. One side of the second protrusion 146 is fixedly connected to the nozzle 12. A first motor 147 is fixedly connected to the bottom of the fixing block 11. A second threaded rod 148 is fixedly connected to the output shaft of the first motor 147. One end of the second threaded rod 148 extends through to the top of the fixing block 11 and is threadedly connected to a second threaded block 149. One side of the second threaded block 149 is fixedly connected to the sleeve block 141.

[0031] In this embodiment: the adjustment mechanism 14 drives the second threaded rod 148 through the first motor 147 to drive the second threaded block 149 to rise and fall along the guide rod 10. Then, through the linkage transmission structure composed of the sleeve block 141, the first connecting piece 142, the adjustment block 143, and the second connecting piece 144, the nozzle 12 makes an arc-shaped deflection movement with the first concave block 145 as the center. It can flexibly adjust the spraying angle of the nozzle according to the direction and width of the seam of the protective clothing, so that the adhesive can be accurately sprayed into the seam. This completely solves the problems of missed spraying and uneven adhesive layer distribution that are easy to occur in traditional fixed-angle spraying, and effectively improves the sealing performance of the seam.

[0032] Specifically, the second drive mechanism 15 includes a second motor 151 fixedly connected to the bottom of the square plate 9. The output shaft of the second motor 151 is fixedly connected to a drive gear 152. A driven gear 153 is sleeved on the surface of the guide rod 10. The drive gear 152 and the driven gear 153 mesh with each other.

[0033] In this embodiment: the second drive mechanism 15 drives the active gear 152 to rotate through the second motor 151. The meshing transmission between the active gear 152 and the driven gear 153 drives the guide rod 10 to complete circumferential rotation, thereby driving the nozzle 12 to achieve 360-degree directional adjustment around the axis of the guide rod. The spray coverage of the nozzle can be flexibly changed without moving the main sewing head position. It can also complete all-round adhesive spraying operations for special positions that are difficult to cover by conventional direct spraying, such as corner seams and irregular arc seams of protective clothing. No manual secondary glue application is required, which greatly improves the spraying quality and work efficiency of complex sewing positions.

[0034] Specifically, the circulation mechanism 16 includes a water pump 161 fixedly connected to the bottom of the water tank 8. The water inlet of the water pump 161 is connected to a water inlet pipe 162. One end of the water inlet pipe 162 extends into the inner cavity of the water tank 8. The water outlet of the water pump 161 is connected to a telescopic hose 163. One end of the telescopic hose 163 is connected to the liquid inlet pipe 13.

[0035] In this embodiment: the flow mechanism 16 provides stable delivery power through the water pump 161, draws adhesive from the water tank 8 through the water inlet pipe 162, and then delivers it to the nozzle 12 through the telescopic hose 163. The deformable characteristics of the telescopic hose 163 can fully adapt to the positional shift of the nozzle during angular deflection and circumferential rotation. There will be no problems of pipe bending, blockage or leakage during the whole process, which ensures the continuous and stable delivery pressure of adhesive and avoids failures such as interrupted spraying or sudden changes in spray volume, making the spraying operation smooth and uniform throughout.

[0036] Specifically, the extrusion mechanism 18 includes a third fixed plate 181 fixedly connected to the output shaft of the second cylinder 17. A baffle 182 is provided on the top of the third fixed plate 181, and a second recess 183 is provided on the bottom of the third fixed plate 181. A conveying roller 184 is rotatably connected to the inner cavity of the second recess 183. Limiting rods 185 are fixedly connected to both sides of the top of the second recess 183. One end of the limiting rod 185 passes through the top of the third fixed plate 181 and is fixedly connected to the baffle 182. A second spring 186 is sleeved on the surface of the limiting rod 185. The two ends of the second spring 186 are fixedly connected to the third fixed plate 181 and the second recess 183, respectively.

[0037] In this embodiment, the extrusion mechanism 18 drives the third fixed plate 181 to press down through the second cylinder 17. With the guiding action of the limit rod 185 and the elastic buffering of the second spring 186, the conveying roller 184 is always in contact with the seam position after the adhesive has been sprayed with constant flexible pressure. This not only evenly rolls and spreads the surface adhesive layer, allowing the adhesive to completely fill every gap in the seam, but also adapts to the slight undulations on the surface of the protective clothing fabric to avoid damaging the fabric. At the same time, the rolling mode of the conveying roller 184 can also help to drive the protective clothing to move smoothly. While completing the pressing operation, the fabric is directionally conveyed, making the connection between each process smoother.

[0038] Specifically, a guide frame 19 is fixedly connected to the bottom of the first fixed plate 2, and a slider 20 is slidably connected to the inner cavity of the guide frame 19. One side of the slider 20 is fixedly connected to the first threaded block 44.

[0039] In this embodiment, the guide frame 19, the internally sliding slider 20, and the first threaded block 44 form a linkage, providing precise limiting guidance for the lateral movement of the first threaded block 44. This ensures that the first threaded block 44 will not deflect circumferentially during its movement along the first threaded rod 42, avoiding the problems of jamming and deviation when the support block 45 drives the fixed mechanism 3 to move. At the same time, it can also share the radial load borne by the first threaded rod 42, reduce the wear of the threaded rod, and significantly extend the service life of the components of the first drive mechanism 4, allowing the position adjustment accuracy of the fixed mechanism 3 to remain stable over a long period of time.

[0040] Specifically, one end of the second threaded rod 148 is fixedly connected to a limiting block 21, which is circular in shape.

[0041] In this embodiment, the circular limiting block 21 fixed to the end of the second threaded rod 148 can physically limit the maximum lifting stroke of the second threaded block 149, completely preventing the second threaded block 149 from coming off the end of the second threaded rod 148 during movement. This prevents the adjustment mechanism 14 from experiencing component detachment or uncontrolled deflection of the nozzle 12, effectively improving the safety and stability of the adjustment mechanism 14 during operation, reducing the probability of equipment downtime, and reducing daily maintenance costs.

[0042] An automatic seam sealing and taping device for protective clothing, the method of using which includes the following steps: Step 1: Place the fabric to be sewn on top of the conveyor 1 and the first fixing plate 2, stack the edges of the two pieces of fabric, and then start the dual-axis motor 41. The output shaft of the dual-axis motor 41 drives the first threaded rod 42 to rotate. When the first threaded rod 42 rotates, it will drive the first threaded block 44 to move. The first threaded block 44 drives the support block 45 to move. The support block 45 drives the fixing mechanism 3 to move, so that the placement position of the fixing mechanism 3 can be adjusted according to the size of the fabric, thereby fixing fabrics of different specifications.

[0043] Step 2: When the placement plate 31 moves above the fabric, the electric telescopic rod 33 is activated. The output end of the electric telescopic rod 33 drives the extrusion plate 32 to move downward. The extrusion plate 32 drives the short rod 35 to move downward. The short rod 35 drives the slide plate 34 to slide downward on the surface of the electric telescopic rod 33. When the extrusion plate 32 moves, it will cause the first spring 36 to be stretched. When the extrusion plate 32 moves downward, it will cause the ball bearing at the bottom to contact the fabric, thus completing the fixation of the fabric and making it less likely to shift after placement.

[0044] Step 3: Start the first cylinder 5. The output shaft of the first cylinder 5 drives the second fixed plate 6 to move downward. The second fixed plate 6 drives the sewing head 7 to move downward. When the sewing head 7 moves to the designated position, start the sewing head 7 to sew the two overlapping pieces of fabric together.

[0045] Step 4: While sewing, start the water pump 161. The water pump 161 delivers the adhesive from the inner cavity of the water tank 8 to the nozzle 12 through the water inlet pipe 162 and the telescopic hose 163. The adhesive is sprayed onto the sewn fabric through the nozzle 12, which can effectively improve the tightness of the fabric connection. When spraying the adhesive, the first motor 147 is started. The output shaft of the first motor 147 drives the second threaded rod 148 to rotate. The second threaded rod 148 drives the second threaded block 149 to move. The second threaded block 149 drives the sleeve block. 141 slides on the surface of guide rod 10. When the sleeve block 141 moves, it will drive the first connecting member 142 to move. The first connecting member 142 drives one end of the adjusting block 143 to move upward. The other end of the adjusting block 143 drives the second connecting member 144 to move. When the second connecting member 144 moves, it will cause the nozzle 12 to move in an arc around the first concave block 145. The nozzle 12 drives the second protrusion 146 to rotate in the inner cavity of the first concave block 145, thereby adjusting the spraying angle of the nozzle 12 and making the adhesive spraying more uniform.

[0046] Step 5: Start the second motor 151. The output shaft of the second motor 151 drives the drive gear 152 to rotate. The drive gear 152 drives the driven gear 153 to rotate. The driven gear 153 drives the fixed block 11 to rotate through the guide rod 10. The fixed block 11 drives the nozzle 12 to rotate through the adjustment mechanism 14, thereby adjusting the spraying position of the nozzle 12 and increasing the spraying area.

[0047] Step Six: After the fabric is sewn and the adhesive is sprayed, start the conveyor device 1 to transport the fabric backward. When the fabric moves to the bottom of the extrusion mechanism 18, start the second cylinder 17. The output end of the second cylinder 17 drives the third fixed plate 181 to move downward. The third fixed plate 181 drives the second concave block 183 to move downward through the baffle 182 and the limit rod 185. The second concave block 183 drives the conveyor roller 184 to move, so that the conveyor roller 184 contacts the fabric. Then start the conveyor roller 184. The conveyor roller 184 rolls at the position where the adhesive is sprayed on the fabric, which effectively improves the adhesion of the adhesive and makes the fabric less likely to separate.

10. An automatic seam sealing and taping device for protective clothing, characterized in that: Its usage includes the following steps: Step 1: Place the fabric to be sewn on top of the conveying device (1) and the first fixing plate (2), stack the edges of the two pieces of fabric, and then start the dual-axis motor (41). The output shaft of the dual-axis motor (41) drives the first threaded rod (42) to rotate. When the first threaded rod (42) rotates, it will drive the first threaded block (44) to move. The first threaded block (44) drives the support block (45) to move. The support block (45) drives the fixing mechanism (3) to move. The position of the fixing mechanism (3) can be adjusted so that the fixing mechanism (3) can be adjusted according to the size of the fabric, thereby fixing fabrics of different specifications. Step 2: When the placement plate (31) moves above the fabric, start the electric telescopic rod (33). The output end of the electric telescopic rod (33) drives the extrusion plate (32) to move downward. The extrusion plate (32) drives the short rod (35) to move downward. The short rod (35) drives the slide plate (34) to slide downward on the surface of the electric telescopic rod (33). When the extrusion plate (32) moves, it will drive the first spring (36) to stretch. When the extrusion plate (32) moves downward, it will make the ball bearing at the bottom of the extrusion plate contact the fabric, thus completing the fixation of the fabric and making it less likely to shift after placement. Step 3: Start the first cylinder (5). The output shaft of the first cylinder (5) drives the second fixed plate (6) to move downward. The second fixed plate (6) drives the sewing head (7) to move downward. When the sewing head (7) moves to the designated position, start the sewing head (7) to sew the two overlapping pieces of fabric together. Step 4: While sewing, start the water pump (161). The water pump (161) delivers the adhesive in the inner cavity of the water tank (8) to the nozzle (12) through the water inlet pipe (162) and the telescopic hose (163). The adhesive is sprayed onto the sewn fabric through the nozzle (12), which can effectively improve the tightness of the fabric connection. When spraying the adhesive, the first motor (147) can be started. The output shaft of the first motor (147) drives the second threaded rod (148) to rotate. The second threaded rod (148) drives the second threaded block (149) to move. The second threaded block (149) drives the sleeve block (149) to move. 41) Sliding on the surface of the guide rod (10), the sleeve block (141) will drive the first connector (142) to move when it moves. The first connector (142) will drive one end of the adjusting block (143) to move upward. The other end of the adjusting block (143) will drive the second connector (144) to move. When the second connector (144) moves, the nozzle (12) will make an arc-shaped movement around the first concave block (145) as the center. The nozzle (12) will drive the second protrusion (146) to rotate in the inner cavity of the first concave block (145), thereby adjusting the spraying angle of the nozzle (12) and making the adhesive spraying more uniform. Step 5: Start the second motor (151). The output shaft of the second motor (151) drives the drive gear (152) to rotate. The drive gear (152) drives the driven gear (153) to rotate. The driven gear (153) drives the fixed block (11) to rotate through the guide rod (10). The fixed block (11) drives the nozzle (12) to rotate through the adjustment mechanism (14), thereby adjusting the spraying position of the nozzle (12) and increasing the spraying area. Step 6: After the fabric is sewn and the adhesive is sprayed, start the conveying device (1) to convey the fabric and move it backward. When the fabric moves to the bottom of the extrusion mechanism (18), start the second cylinder (17). The output end of the second cylinder (17) drives the third fixed plate (181) to move downward. The third fixed plate (181) drives the second concave block (183) to move downward through the baffle (182) and the limit rod (185). The second concave block (183) drives the conveying roller (184) to move, so that the conveying roller (184) contacts the fabric. Then start the conveying roller (184). The conveying roller (184) rolls at the position where the adhesive is sprayed on the fabric, which effectively improves the adhesion tightness of the adhesive and makes the fabric less likely to separate.
