Description

TECHNICAL FIELD

[0001] The application belongs to the field of film coating equipment, and particularly relates to a self-adaptive tension traction device. BACKGROUND

[0002] In the current production process, a film coating machine is often used to bond multiple target prints on the same target film material, and the target prints are separated into several independent products through a subsequent cutting device.

[0003] However, due to the difference in the ability to withstand tension between the part of the film material with the prints and the part without the prints, the traditional traction device is prone to cause the film material to stretch and deform during traction, especially the part of the film material without the prints has weak ability to withstand tension, while the part with the prints can withstand greater tension due to the bonding relationship, causing the overall deformation of the film material, which further causes the cutting device to cut the position of the prints in the subsequent cutting process, which may cause damage to the prints, inaccurate die cutting or waste, affecting product quality and production efficiency. Therefore, it is necessary to solve the above technical problems. SUMMARY

[0004] The purpose of the embodiment of the application is to provide a self-adaptive tension traction device to solve the technical problem that the film coating machine product is prone to stretch and deform during traction in the prior art.

[0005] To achieve the above purpose, the technical solution adopted by the application is to provide a self-adaptive tension traction device, comprising:

[0006] a film coating machine for bonding a target film material on a target print;

[0007] a traction mechanism arranged at intervals from the film coating machine and used for traction of a composite product from the film coating machine;

[0008] an adjustment mechanism arranged between the film coating machine and the traction mechanism, the adjustment mechanism comprising a wall plate, front and rear guide rollers installed in parallel at intervals on the wall plate and used for sequentially receiving the composite product, and a positive pressure air source installed on the wall plate, the airflow blown out of the air outlet of the positive pressure air source causing the composite product between the front and rear guide rollers to have a tendency to move away from the air outlet;

[0009] a detection unit arranged on the path of the composite product away from or close to the air outlet, used for detecting the relative position between the composite product and the air outlet, and electrically connected with the traction mechanism.

[0010] Optionally, the detection unit comprises a first sensor installed on the wallboard and configured to detect the position of the composite product, and the traction mechanism comprises a traction roller and a servo motor connected to the traction roller and configured to drive the traction roller.

[0011] The first sensor is communicatively connected to the servo motor, and the front guide roller and the rear guide roller are both higher than the first sensor in the height direction of the wallboard.

[0012] Optionally, the detection unit further comprises a second sensor installed on the wallboard and configured to detect the position of the composite product, and the second sensor is communicatively connected to the servo motor.

[0013] The second sensor is lower than the first sensor in the height direction of the wallboard.

[0014] Optionally, the front guide roller is close to the film laminating machine, and the rear guide roller is close to the traction mechanism.

[0015] The adjustment mechanism further comprises a fixed shaft connected to the wallboard and coaxially arranged with the front guide roller, and a one-way bearing arranged between the front guide roller and the fixed shaft, the one-way bearing being configured to rotate in one direction to enable the composite product passing through the front guide roller to be delivered from the film laminating machine to the traction mechanism.

[0016] Optionally, the positive pressure air source has an adjustable air outlet size.

[0017] The self-adaptive tension traction device provided by the present application has the following advantages: compared with the prior art, in the self-adaptive tension traction device provided by the present application, an adjustment mechanism is arranged between the film laminating machine and the traction mechanism. Since the adjustment mechanism is designed with a positive pressure air source and the airflow blown out of the air outlet of the positive pressure air source makes the composite product between the front guide roller and the rear guide roller have a tendency to move away from the air outlet, the composite product from the film laminating machine can be flexibly tensioned by the air force formed by the positive pressure air source during the process of passing through the front guide roller and the rear guide roller in turn. Since the airflow blown from the positive pressure air source to the composite product can escape from the surface of the composite product after tensioning the composite product, the positive pressure air source forms a flexible tensioning effect on the composite product. Therefore, the self-adaptive tension traction device provided by the present application can significantly reduce the stretching deformation of the composite product from the film laminating machine during the traction process, and the printed product is also less likely to be damaged during the subsequent product cutting process, which is much better than the prior art.

[0025] Please refer to Figure 1 Now a self-adaptive tension traction device provided by the embodiment of the present application is described. The self-adaptive tension traction device comprises a laminating machine 100, a traction mechanism 200, an adjusting mechanism and a detection unit. Wherein:

[0026] The laminating machine 100 is used to combine a target film material on a target printed matter; the traction mechanism 200 is arranged at intervals with the laminating machine 100 and is used to traction a composite product 500 from the laminating machine 100; the adjusting mechanism is arranged between the laminating machine 100 and the traction mechanism 200, the adjusting mechanism comprises a wall plate 300, a front guide roller 301 and a rear guide roller 302 which are installed on the wall plate 300 in parallel and at intervals and are used to sequentially support and send the composite product 500, and further comprises a positive pressure air source 303 which is installed on the wall plate 300, the airflow blown out from the air outlet of the positive pressure air source 303 makes the composite product 500 between the front guide roller 301 and the rear guide roller 302 have a tendency to move away from the air outlet; the detection unit is arranged on the path of the composite product 500 moving away from or close to the air outlet, and is used to detect the relative position between the composite product 500 and the air outlet, the detection unit is electrically connected with the traction mechanism 200.

[0027] According to the above structure provided in the embodiment, in the self-adaptive tension traction device provided by the embodiment, the adjusting mechanism is arranged between the laminating machine 100 and the traction mechanism 200, since the positive pressure air source 303 is designed in the adjusting mechanism and the airflow blown out from the air outlet of the positive pressure air source 303 makes the composite product 500 between the front guide roller 301 and the rear guide roller 302 have a tendency to move away from the air outlet, thus the composite product 500 from the laminating machine 100 can be tensioned by the wind force formed by the positive pressure air source 303 during sequentially passing through the front guide roller 301 and the rear guide roller 302. Since the wind blown from the positive pressure air source 303 to the composite product 500 can escape from the surface of the composite product 500 after tensioning the composite product 500, thus the positive pressure air source 303 forms a flexible tensioning technical effect on the composite product 500, so that the self-adaptive tension traction device provided by the embodiment can significantly reduce the tensile deformation of the composite product 500 from the laminating machine 100 during the traction process, and the printed matter is also less likely to be damaged during the subsequent product cutting process by the cutting device 400, at the same time, the structure for realizing stable tension is quite simple, and the operation and maintenance are convenient, which is much better than the prior art.

[0028] For the convenience of description, please refer to Figure 1, the front guide roller 301 and the rear guide roller 302 are at the same height in the height direction of the wallboard 300 and are both lower than the positive pressure air source 303, according to the above structure provided in the embodiment, the front guide roller 301 and the rear guide roller 302 at the same height can make the composite product 500 between the front guide roller 301 and the rear guide roller 302 realize flexible tensioning effect under the action of its own weight and the wind force provided by the positive pressure air source 303, on the one hand, it can effectively reduce the air volume demand of the positive pressure air source 303, thereby having energy-saving effect, on the other hand, it can also effectively keep the composite product 500 having proper tension, which is beneficial to better avoid the tensile deformation of the composite product 500 in the process of pulling the composite product 500 by the self-adaptive tension traction device in the embodiment, it can be understood that the front guide roller 301 and the rear guide roller 302 are not at the same height in the height direction of the wallboard 300 also have the same technical effect.

[0029] In another embodiment of the application, referring to Figure 1 , the detection unit comprises a first sensor 304 installed on the wallboard 300 and used for detecting the position of the composite product 500, the traction mechanism 200 comprises a traction roller 201 and a servo motor 202 connected to the traction roller 201 and used for driving the traction roller 201; the first sensor 304 is communicatively connected to the servo motor 202, and the front guide roller 301 and the rear guide roller 302 are both higher than the first sensor 304 in the height direction of the wallboard 300.

[0030] According to the above structure provided in the embodiment, the first sensor 304 installed on the wallboard 300 and lower than the front guide roller 301 and the rear guide roller 302 can control the servo motor 202 communicatively connected thereto by detecting the position of the composite product 500, so that the traction roller 201 driven by the servo motor 202 can form different rotating speeds to make the composite product 500 between the front guide roller 301 and the rear guide roller 302 always higher than the position where the first sensor 304 is located in the height direction of the wallboard 300, which makes the composite product 500 always have sufficient margin before entering the traction mechanism 200, thereby effectively avoiding the tensile deformation of the composite product 500 due to the change of tension, which is also beneficial to better avoid the tensile deformation of the composite product 500 in the process of pulling the composite product 500 by the self-adaptive tension traction device in the embodiment.

[0031] In another embodiment of the application, referring to Figure 1 , the detection unit further comprises a second sensor 305 installed on the wallboard 300 and used for detecting the position of the composite product 500, the second sensor 305 is communicatively connected to the servo motor 202; the second sensor 305 is lower than the first sensor 304 in the height direction of the wallboard 300.

[0032] According to the above structure provided in the embodiment, the second sensor 305 for detecting the position of the composite product 500 can keep the composite product 500 between the front guide roller 301 and the rear guide roller 302 always in the height direction of the wallboard 300 between the first sensor 304 and the second sensor 305 according to the same technical principle as the first sensor 304, so that the composite product 500 can have a margin of the preset target length before entering the traction mechanism 200, i.e., when the composite product 500 is lowered to the second sensor 305, the servo motor 202 starts or is switched from the slow state to the linear acceleration state, and vice versa, when the lowered position of the composite product 500 is raised to the first sensor 304, the servo motor 202 stops or reduces the speed to reduce the traction speed, and the above process is repeated to automatically adjust the composite product 500, so that the composite product 500 can not only effectively avoid stretching deformation, but also always be in the action range of the positive pressure air source 303 to always keep appropriate tension, which is also conducive to the self-adaptive tension traction device in the embodiment to better avoid stretching deformation of the composite product 500 during traction of the composite product 500.

[0033] In another embodiment of the present application, referring to Figure 1 , the front guide roller 301 is close to the film laminating machine 100, and the rear guide roller 302 is close to the traction mechanism 200; the adjusting mechanism further comprises a fixed shaft 306 connected to the wallboard 300 and coaxially arranged with the front guide roller 301, and a one-way bearing 307 arranged between the front guide roller 301 and the fixed shaft 306, the one-way bearing 307 is used for one-way rotation to make the composite product 500 passing through the front guide roller 301 only be able to be delivered from the film laminating machine 100 to the traction mechanism 200.

[0034] According to the above structure provided in the embodiment, the one-way bearing 307 arranged between the front guide roller 301 and the fixed shaft 306 can make the front guide roller 301 only deliver the composite product 500 from the film laminating machine 100 to the traction mechanism 200, so that the composite product 500 between the front guide roller 301 and the rear guide roller 302 can be effectively prevented from returning to the film laminating machine 100 side when the machine is stopped, and the function of automatically keeping the current position of the composite product 500 when the machine is stopped is realized, which is conducive to the self-adaptive tension traction device in the embodiment to better avoid stretching deformation of the composite product 500 during restarting of traction of the composite product 500.

[0035] In another embodiment of the present application, referring to Figure 1, the positive pressure air source 303 can adopt a fan with a variable frequency speed regulation function, or can adopt an air compressor to provide compressed air, a proportional control valve is used to control the air volume, and in the embodiment, the fan with the variable frequency speed regulation function is adopted; according to the above structure provided in the embodiment, the positive pressure air source 303 capable of adjusting the air volume can be suitable for self-adaptive tensioning of the composite product 500 with different materials, different thicknesses and different widths, so as to facilitate the self-adaptive tension traction device in the embodiment to be applied in more working conditions.

[0036] The above only describes the preferred embodiments of the present application and is not used to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
