[0029] In one embodiment of the present invention, a film bonding device is provided. Figures 1 to 5 The adhesive film bonding device is used to bond the adhesive film and the product into an integrated structure. The product can be an elastic band for clothing, a shoulder strap or other belt-like structures.

[0030] The specific structure of the film bonding device is as follows: it includes a fixed frame 1, a film discharge device 2, a product discharge device, and an adjustment mechanism and a bonding mechanism arranged on the side of the fixed frame 1. The film discharge device 2 is used to convey the film, the product discharge device is used to convey long strip products, and the bonding mechanism is used to bond the film and the product, and is also used to drive the movement of the finished product after bonding.

[0031] The adhesive film unloading device 2 includes an unloading reel for storing adhesive film, and the product unloading device includes an unloading reel for storing products. Both the adhesive film on the adhesive film unloading device 2 and the product on the product unloading device can be transported to the bonding mechanism.

[0032] The specific structure of the bonding mechanism is as follows: it includes an upper bonding mechanism 3 and a lower bonding mechanism arranged below the upper bonding mechanism 3, and the adhesive film and the product pass through the upper bonding mechanism 3 and the lower bonding mechanism for bonding; the adjustment mechanism is used to adjust the distance between the upper bonding mechanism 3 and the lower bonding mechanism to adapt to adhesive films and products of different thicknesses. According to the fabrics of products of different thicknesses, the distance and pressure between the upper bonding mechanism 3 and the lower bonding mechanism are adjusted to adapt to fabrics of products of different thicknesses, and the stability of the extrusion pressure during the conveying process can be ensured, and the bonding quality of the adhesive film and the product can be ensured.

[0033] The specific structure of the upper bonding mechanism 3 is as follows: Figure 2 and Figure 3 , which includes a first driving mechanism, an upper driving wheel 32, an upper auxiliary wheel 33, an upper adjusting wheel 34, and a first conveyor belt 35 for connecting the upper driving wheel 32, the upper auxiliary wheel 33 and the upper adjusting wheel 34. Under the drive of the first driving mechanism, the upper driving wheel 32 rotates to drive the upper auxiliary wheel 33 and the upper adjusting wheel 34 to rotate. The first driving mechanism is preferably a motor.

[0034] The upper bonding mechanism 3 also includes two leveling rollers 37 respectively arranged on both sides below the upper driving wheel 32. The first conveyor belt passes between the two leveling rollers. The multiple leveling rollers are used to adjust the tension and level the first conveyor belt to ensure the quality of the subsequent extruded bonding film and products.

[0035] The specific structure of the lower bonding mechanism is as follows: Figure 2 and Figure 3, which includes a second driving mechanism, a lower driving wheel 41 disposed under the upper auxiliary wheel 33, a lower adjusting wheel 42 disposed under the upper adjusting wheel 34, and a second conveyor belt for connecting the lower driving wheel 41 and the lower adjusting wheel 42. The upper auxiliary wheel 33 cooperates with the lower driving wheel 41, and the upper adjusting wheel 34 cooperates with the lower adjusting wheel 42. The second driving mechanism is used to drive the lower driving wheel 41 to rotate, so as to drive the lower adjusting wheel 42 to rotate, so that the film and the product pass through between the upper auxiliary wheel 33 and the lower driving wheel 41, and between the upper adjusting wheel 34 and the lower adjusting wheel 42 in sequence.

[0036] The specific structure of the adjustment mechanism is as follows: it includes a first adjustment mechanism 5, which includes a rotating member arranged on the side of the fixing frame 1. The upper auxiliary wheel 33 of the upper bonding mechanism 3 is rotatably connected to the rotating member. When the rotating member rotates, the distance between the upper auxiliary wheel 33 and the lower driving wheel 41 increases or decreases. The upper auxiliary wheel 33 and the lower driving wheel 41 are the starting ends of the transmission, and the upper adjustment wheel 34 and the lower adjustment wheel 42 are the terminal ends of the transmission. When the thickness of the product is large, the product and the adhesive film pass through the upper bonding mechanism and the lower bonding mechanism at the same time. Due to the setting of the rotating member, the upper auxiliary wheel 33 is lifted by force, and the distance between the upper auxiliary wheel 33 and the lower driving wheel 41 increases. When the product and the adhesive film pass through, the tension and pressure are adjusted, which is suitable for adhesive films and products of different thicknesses to ensure the bonding quality.

[0037] A specific structure of the rotating member is as follows: Figure 4 It includes a bearing seat 51 fixedly connected to the side of the fixing frame 1, a cross bar 52 rotatably connected to the inner bearing of the bearing seat 51 through a rotating shaft, and the cross bar 52 is fixedly connected to the upper auxiliary wheel 33. By setting a rotating part, when the thickness of the fabric increases, the upper auxiliary wheel 33 is lifted to ensure pressure stability and adapt to different thicknesses of films and products.

[0038] The rotating member further includes a pressure plate 53 disposed on the crossbar 52 . The pressure plate 53 is used to position the upper auxiliary wheel 33 and can adjust the pressure of the upper auxiliary wheel 33 .

[0039] The adjustment mechanism also includes a second adjustment mechanism 6, which includes a third drive mechanism 63 and an adjustment assembly. The specific structure of the adjustment assembly is as follows: it includes a support plate 61 arranged on the side of the fixing frame 1, a protective plate 66 arranged opposite to the support plate 61, and an upper rib 62 arranged between the support plate 61 and the protective plate 66. The support plate 61 is rotatably connected to the fixing frame 1 through a rotating shaft 64, and the rotating shaft 64 is fixed to the side of the fixing frame. The upper adjustment wheel 34 is arranged between the support plate 61 and the protective plate 66, and the upper rib 62 is always in contact with the first conveyor belt 35. The third drive mechanism 63 always presses the first conveyor belt 35 and the upper adjustment wheel 34 to ensure that the upper adjustment wheel 34 and the lower adjustment wheel 42 are kept squeezed.

[0040] The third driving mechanism 63 is also used to drive one end of the support plate 61 to move up and down, so as to drive the support plate 61 to rotate relative to the fixing frame 1 around the rotating shaft 64, thereby driving the upper adjusting wheel 34 to move away from the lower adjusting wheel 42 or to move closer to the lower adjusting wheel 42. The first driving mechanism is preferably a cylinder.

[0041] A connecting shaft is arranged between the support plate 61 and the protection plate 66, and the upper rib 62 is arranged on the connecting shaft and can rotate relative to the connecting shaft. The upper rib 62 is arranged above the upper regulating wheel, and its end facing the first transmission belt is an arc structure.

[0042] The third driving mechanism 63 includes a telescopic rod connected to the connecting shaft and a cylinder connected to the telescopic rod. The telescopic rod can move up and down, and the driving mode of the telescopic rod is electric, hydraulic or pneumatic. The cylinder drives the telescopic rod so that the upper rib 62 always presses against the first conveyor belt 35 and the upper adjustment wheel 34, ensuring that the upper adjustment wheel 34 and the lower adjustment wheel 42 are kept squeezed. When the thickness of the product passing between the upper adjustment wheel 34 and the lower adjustment wheel 42 increases, the telescopic rod moves upward to increase the distance between the upper adjustment wheel 34 and the lower adjustment wheel 42, so that the film and the product pass smoothly, ensuring the stability of the tension of the first conveyor belt and the bonding quality.

[0043] The support plate 61 and the protection plate 66 are connected by fasteners, and the protection plate serves to protect all components between the support plate and the protection plate.

[0044] The support plate 61 and the protective plate 66 are both provided with guide grooves 65 extending along the conveying direction of the adhesive film and the product, and the two guide grooves 65 are arranged opposite to each other. The central axis at the center of the upper adjusting wheel 34 is arranged in the guide groove 65 between the support plate 61 and the protective plate 66, and the central axis at the center of the upper adjusting wheel 34 can move along the length direction of the guide groove on the support plate 61 and the length direction of the guide groove 65 on the protective plate 66. The sides with guide grooves on the support plate 61 and the protective plate 66 are both provided with fixing blocks 67 to limit the upper adjusting wheel 34 from being separated from the guide grooves. One end of the central axis of the upper adjusting wheel 34 is connected to the fixing block 67 on the support plate 61 by a screw, and the other end of the central axis of the upper adjusting wheel 34 is connected to the fixing block 67 on the protective plate 66 by a screw. The central axis at the center of the upper adjusting wheel 34 can move along the length direction of the guide groove on the support plate 61 and the length direction of the guide groove 65 on the protective plate 66, so as to adjust the tightness and parallelism of the first conveyor belt, prevent the first conveyor belt from deviating and running out, and ensure the stability of the tension of the first conveyor belt to ensure the bonding quality.

[0045] When the third driving mechanism 63 drives the adjusting component to rotate relative to the fixed frame 1 with the rotating shaft 64 as the center, the central axis of the upper adjusting wheel 34 is driven to move along the length direction of the guide groove, thereby adjusting the distance between the upper adjusting wheel 34 and the lower adjusting wheel 42. The pressure can be adjusted according to the thickness of the finished product after bonding to ensure the stability of the tension of the first conveyor belt.

[0046] A lower rib 8 is provided below the lower adjusting wheel 42 . The lower rib 8 is fixed to the side of the fixing frame via a rotating shaft. The lower rib 8 rotates relative to the rotating shaft. The end of the lower rib 8 facing the lower adjusting wheel 42 is an arc-shaped structure.

[0047] The second adjustment mechanism 6 further includes a locking mechanism 12. A fixing plate is provided between the protection plate and the support plate. The locking mechanism 12 includes a locking member provided on the fixing plate. The locking member is used to abut against the upper rib 62. When the distance between the upper adjustment wheel 34 and the lower adjustment wheel 42 increases, the locking member can be loosened to adjust the pressure between the upper rib 62 and the first conveyor belt. The locking member is preferably a bolt with a spring provided on the outer cover.

[0048] When there is a tape or film on the first conveyor belt, the upper rib 62 contacts the first conveyor belt to scrape off the tape or film stuck on the first conveyor belt, and the lower rib contacts the second conveyor belt to scrape off the tape or film stuck on the second conveyor belt. Since the tape and film enter from the starting end of the first conveyor belt and the second conveyor belt and come out from the exit end of the first conveyor belt and the second conveyor belt, they may adhere to the first conveyor belt or the surface of the second conveyor belt due to viscosity or static electricity. The bottom of the upper rib 62 contacts the first conveyor belt, which can push the tape or film thereon to fall downward. Then, as the subsequent tape becomes longer and longer, it will no longer adhere to the first conveyor belt under the action of gravity. Similarly, the bottom of the lower rib contacts the second conveyor belt, which can push the tape or film thereon upward. Then, as the subsequent tape becomes longer and longer, it will no longer adhere to the second conveyor belt under the action of gravity.

[0049] The upper bonding mechanism 3 also includes an upper heating plate 31 arranged between the support plate and the protective plate. The upper heating plate 31 is arranged on the side of the support plate 61 away from the side of the fixing frame. The upper auxiliary wheel 33 and the upper adjusting wheel 34 are respectively arranged on both sides of the upper heating plate 31. The upper heating plate 31 rotates as the adjusting component rotates. The length direction of the upper heating plate 31 is consistent with the conveying direction of the adhesive film and the product, and the adhesive film and the upper part of the product passing between the upper auxiliary wheel 33 and the upper adjusting wheel 34 can be heated.

[0050] The lower bonding mechanism also includes a lower heating plate 43 disposed on the side of the fixing frame 1. The lower heating plate 43 is disposed below the upper heating plate 31. The two are disposed opposite to each other. The upper heating plate 31 corresponds to the first conveyor belt, and the upper heating plate 31 corresponds to the second conveyor belt. The lower heating plate 43 is disposed between the lower driving wheel 41 and the lower adjusting wheel 42, and can heat the adhesive film and the lower part of the product passing between the upper auxiliary wheel 33 and the upper adjusting wheel 34. Both the upper heating plate 31 and the lower heating plate 43 can be heated to a preset temperature to provide heat so that the adhesive film and the product are thermally pressed and bonded.

[0051] At least one positioning block 10 is arranged between the upper heating plate 31 and the lower heating plate 43. The upper end of the positioning block 10 is connected to the upper heating plate 31, and the lower end thereof is fixed to the lower heating plate 43. The upper end of the positioning block 10 is provided with an adjustment hole of a preset length. The length direction of the adjustment hole is the vertical direction. A fastener is installed in the adjustment hole. When the third driving mechanism is driven, the upper heating plate 31 can be displaced accordingly. Since the upper heating plate 31 rotates with the rotation of the support plate 61, the upper heating plate 31 can move along the adjustment hole.

[0052] The bonding device further comprises at least one tensioning device 9 arranged under the second conveyor belt, the tensioning device 9 being used to tension the second conveyor belt or the first conveyor belt, and the tensioning device 9 is arranged under the second conveyor belt and / or on the first conveyor belt. Figure 5 The tensioning device 9 includes a tensioning wheel 91, two connecting rods 92 respectively connected to the two ends of the tensioning wheel 91, and a connecting plate 93 connected to the two connecting rods 92. The tensioning wheel 91 is in conflict with the second conveyor belt, or the tensioning wheel 91 is in conflict with the first conveyor belt.

[0053] When a tensioning device 9 is respectively provided on both sides of the lower side of the second conveyor belt, a fourth driving mechanism is provided below the tensioning device 9, and the fourth driving mechanism includes a push rod 11 that can move up and down, and the connecting plate 93 is provided on the upper part of the push rod. Driven by the fourth driving mechanism, the push rod pushes the connecting plate 93 to move up and down, thereby driving the tensioning wheel 91 to move up and down. When the push rod pushes the connecting plate 93 to move upward, it drives the connecting rod to move upward, thereby driving the tensioning wheel 91 to press against the second conveyor belt. By providing a tensioning device, the tension of the first conveyor belt and the second conveyor belt is adjusted, and the first conveyor belt and the second conveyor belt are guided to ensure that the first conveyor belt and the second conveyor belt will not deviate, and the extrusion force of the first conveyor belt and the second conveyor belt is stable, so that the heated adhesive film and the product can be well bonded into an integrated structure.

[0054] When a tensioning device 9 is respectively provided on both sides of the second conveyor belt, one tensioning device 9 presses against the lower driving wheel at the second conveyor belt, thereby squeezing the lower driving wheel and the upper auxiliary wheel, and the other tensioning device 9 presses against the lower adjusting wheel at the first conveyor belt, thereby squeezing the lower adjusting wheel and the upper adjusting wheel, the tension of the first conveyor belt and the second conveyor belt can be better adjusted.

[0055] The adhesive film bonding device provided by the present invention can be provided in plurality, and can be loaded separately without interfering with each other. Due to the separate loading, the temperature, speed and other aspects can be adjusted, the quality can be well controlled, and the operation efficiency of the equipment can be improved.

[0056] The adhesive film bonding device provided by the present invention adjusts the spacing and pressure between the upper bonding mechanism and the lower bonding mechanism through an adjustment mechanism to be suitable for product fabrics and adhesive films of different thicknesses, and can ensure the stability of the extrusion pressure during transportation and ensure the bonding quality of the adhesive film and the product.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
