Description

Technical Field

[0001] The utility model relates to the field of packaging carrier board manufacturing equipment, in particular to a segmented speed-regulating packaging carrier board film laminating flow line. Background Art

[0002] In the manufacturing process of packaging carriers, the film laminating process is a key step in improving the surface performance of the carriers, and it is usually necessary to cooperate with pre-treatment, preheating and other processes to form a continuous production line. In the existing technology, the typical process of the packaging carrier film laminating production line includes pre-treatment, cleaning, preheating, film laminating and cooling. Specifically: first, the PT pre-treatment machine chemically cleans or activates the surface of the packaging carrier; then, the cleaning machine further removes the tiny particle impurities on the surface of the packaging carrier; then, the packaging carrier passes through the preheating machine for temperature adjustment, the film laminating machine to complete the film lamination, and the cooling machine to achieve shaping and cooling. Among them, in order to improve production efficiency, the packaging carrier is often continuously transported in the production line by a conveyor roller group, such as the three-piece conveyor roller for the packaging carrier provided by the patent with announcement number CN217779944U.

[0003] However, in existing laminating production lines, the various equipment is often directly connected. This leads to the following problems: The pre-processing equipment (including the pre-processor) and the exposure processing equipment (including the cleaning, preheating, laminating, and cooling equipment) typically utilize different conveyor speeds due to differing process requirements. Due to this significant speed difference, direct connection between the packaging carriers and the conveyor rollers can easily cause relative sliding friction. This friction can cause scratches and marks on the packaging carrier surface, seriously affecting product yield. For example, the conveyor speed in the pre-processing section is typically set at 1.4m / s to ensure effective processing. However, in the exposure processing section, the conveyor speed must be increased to at least 2.0m / s to match the processing rhythm of the various equipment. Consequently, the conveyor speed of the packaging carriers switches instantly from a low speed of 1.4m / s to a high speed of 2.0m / s, resulting in significant friction on the packaging carriers.

[0004] Furthermore, before laminating the film, the laminator typically heats and pre-presses the film for 1-3 seconds to ensure the bond strength between the film layer and the package carrier. This process requires the conveyor speed to be reduced or stopped to facilitate pre-pressing and positioning. However, the existing conveyor structure can only continuously convey at a set speed, so the conveyor at the front of the laminator can only be temporarily stopped during the heating and pre-pressing. This causes the gap between the subsequent package carriers and the previous one to gradually decrease, making collisions and stacking (i.e., board chasing) more likely to occur. This not only affects production continuity but can also cause secondary damage to the package carriers due to collisions. Although setting a larger gap between the package carriers can address this problem to some extent, this approach significantly reduces conveyor efficiency.

[0005] In summary, the utility model provides a kind of subsection speed-regulating type packaging load plate film pasting flow transfer line. Utility model content

[0006] The utility model discloses a kind of subsection speed-regulating type packaging load plate film pasting flow transfer lines, to solve the problem mentioned in the above background art, in the existing packaging load plate film production line, it can cause packaging load plate damage due to the transmission speed mutation between pre-treatment section equipment and exposure processing section equipment, and dynamic speed regulation cannot be carried out for pre-press positioning, and it can cause the phenomenon of chasing board.

[0007] The utility model is implemented by the following technical solutions:

[0008] A kind of subsection speed-regulating type packaging load plate film pasting flow transfer line, including PT pre-treatment machine, cleaning machine, preheating machine, film applicator and cooling machine sequentially arranged, transmission structure is equipped between every two adjacent equipment, the transmission structure between PT pre-treatment machine and cleaning machine is variable speed cross connection transmission structure, the variable speed cross connection transmission structure includes frame body, controller and three transmission sections distributed in sequence according to transmission direction, each transmission section includes transmission structure body and transmission drive mechanism.

[0009] In the utility model, variable speed cross connection transmission structure with three transmission sections is arranged between PT pre-treatment machine and cleaning machine, so two different transmission speeds can be respectively docked by the first and last two transmission sections, thereby avoiding packaging load plate directly experiencing speed mutation, so that packaging load plate can be effectively prevented from being damaged due to receiving greater friction, and meanwhile, three transmission sections can be cooperated for speed regulation, so that the spacing between front and rear packaging load plates can be pulled apart in the transmission process, so that the spacing required when film applicator is heated and pre-pressed can be adapted, and the phenomenon of chasing board can be avoided.

[0010] Further, the transmission structure body includes a set of transmission rollers arranged on the frame body, and the transmission drive mechanism includes a frequency converter, a motor and a detection sensor; the frequency converter and the detection sensor are respectively communicatively connected to the controller, the output end of the frequency converter is connected to the motor, the output end of the motor is connected to the set of transmission rollers, and the detection sensor is configured to detect the packaging load plate on the set of transmission rollers.

[0011] In the above technical solution, the set of transmission rollers is used to carry the packaging substrate and rotate to achieve the effect of conveying the packaging load plate; the detection sensor is used to detect the position of the packaging load plate and transmit the position information to the controller; the controller is used to generate a speed regulation instruction according to the position information and send the speed regulation instruction to the frequency converter; after receiving the speed regulation instruction, the frequency converter can automatically calculate the speed change per second, change the output frequency accordingly, and the motor speed changes accordingly, thereby achieving instant adjustment or smooth adjustment of the conveying speed of the set of transmission rollers.

[0012] Further, the three conveying sections are sequentially arranged as a first conveying section, a second conveying section and a third conveying section, wherein the first conveying section is connected with the PT pre-treatment machine, and the third conveying section is connected with the cleaning machine, the length relationship between the three conveying sections is second conveying section > first conveying section > third conveying section, and the specific length value and speed value of the three conveying sections are adaptively set by the person skilled in the art according to the actual situation.

[0013] In the above technical solution, the segmented independent speed regulation and length gradient design of the three conveying sections can effectively avoid the frictional damage of the packaging board and prevent the chasing board phenomenon. Among them, for avoiding frictional damage: the first conveying section is connected with the PT pre-treatment machine, and the initial speed is set to be consistent with the previous equipment, so as to ensure that the packaging board enters smoothly and avoid the friction caused by the speed difference when entering; the second conveying section undertakes the core speed change task, and can realize low acceleration smooth transition through long distance, so as to avoid the sliding friction of the packaging board and the roller caused by sudden change of speed; the third conveying section is connected with the cleaning machine and the subsequent film laminating machine, and the output speed is set to be consistent with the subsequent equipment, so as to ensure that there is no speed difference when the substrate enters the next process, and the friction risk in the end stage is eliminated. For preventing the chasing board phenomenon: after the packaging board enters the variable speed cross connection conveying structure, the three conveying sections can cooperate to increase the speed, and then actively enlarge the distance between the front and rear packaging boards, so as to reserve safety redundancy for the heating and pre-pressing rhythm of the film laminating machine; after completing the distance enlargement, the speed of the first conveying section is reduced, which not only realizes the connection with the PT pre-treatment machine, but also can avoid the too fast pushing of the subsequent packaging board; the second conveying section is the longest, and can be used as a buffer zone after the distance is enlarged, so as to further maintain the safety distance between the front and rear packaging boards.

[0014] Further, the detection sensor is a photoelectric sensor or a laser sensor.

[0015] Further, the PT pre-treatment machine is arranged outdoors, and the cleaning machine, the pre-heating machine, the film laminating machine and the cooling machine are arranged indoors.

[0016] Further, a transparent dustproof cover plate is arranged above the conveying roller set.

[0023] The technical scheme in the utility model embodiment will be clearly and completely described below with reference to the drawings in the utility model embodiment.

[0024] Embodiment 1

[0025] The utility model provides a segmented speed governing type packaging load board film pasting flow transfer line, including the feeding machine, PT pre -treatment machine, cleaning machine, preheating machine, film pasting machine, cooling machine and receiving machine (not shown in the drawing) of sequence setting, wherein the feeding machine, PT pre -treatment machine are located outdoor, and the cleaning machine, preheating machine, film pasting machine, cooling machine and receiving machine are located indoor. Transmission structure (not shown in the drawing) is arranged between every two adjacent equipment, wherein the transmission structure between PT pre -treatment machine and cleaning machine is speed change cross -linking transmission structure, and the speed change cross -linking transmission structure includes frame body 1, PLC controller and three transmission sections distributed in sequence along the transmission direction. Please refer to Figure 1 And Figure 2 , specifically:

[0026] The three conveying sections are the first conveying section 2, the second conveying section 3 and the third conveying section 4 arranged in sequence, wherein the first conveying section 2 is docked with the PT pre-processor and the third conveying section 4 is docked with the cleaning machine. The length relationship between the three conveying sections is second conveying section 3>first conveying section 2>third conveying section 4.

[0027] Each conveying section includes a conveying structure and a conveying drive mechanism. The conveying structure includes a conveying roller assembly 5 mounted on a frame 1. A transparent dust cover with a handle is located above the three conveying roller assemblies 5 (not shown). The conveying drive mechanism includes a frequency converter, a motor 6, and a laser sensor 7. The frequency converter and laser sensor 7 are each connected to a PLC controller. The frequency converter, motor 6, and PLC controller are installed in an electrical box (not shown) outside the frame 1. The output of the frequency converter is connected to the motor 6, which in turn is connected to the conveying roller assembly 5. The laser sensor 7 is installed at the end of the conveying section, located below the conveying roller assembly 5 and directed toward the package carrier on the conveying roller assembly 5 for detection.

[0028] Based on the above structure, the two conveying sections at the head and tail can be used to connect two different conveying speeds respectively, thereby avoiding the package carrier from experiencing a sudden change in speed, which can effectively prevent the package carrier from being damaged due to large friction. At the same time, the three conveying sections can be used for coordinated speed regulation, thereby widening the distance between the front and rear package carriers during the conveying process, thereby adapting to the distance required by the film laminating machine during heating and pre-pressing, and avoiding the phenomenon of chasing the board. In this embodiment, the following data is substituted for a specific example:

[0029] The length of the package carrier is 51.3cm. The package carrier A8 is defined as the one that arrives at the variable speed jump transmission structure first, and the package carrier B9 is defined as the one that arrives later. The total length of the transmission section is 80cm, of which the length of the first transmission section 2 is 30cm, the length of the second transmission section 3 is 35cm, and the length of the third transmission section 4 is 15cm. Please refer to Figure 3 , each transmission section performs speed regulation and transmission according to the following process:

[0030] 1) Transfer the package carrier A8 from the PT pre-processor to the machine. Specifically:

[0031] The conveying speed of the first conveying section 2 and the second conveying section 3 is 14 cm / s, and the packaging carrier A8 begins to enter the variable speed cross-conveying structure. When the packaging carrier A8 completely enters the first conveying section 2 and the second conveying section 3, the distance between the packaging carrier A8 and the packaging carrier B9 is 10 cm.

[0032] 2) Continue to transfer the package carrier A8, specifically:

[0033] The conveying speeds of the first conveying section 2, the second conveying section 3 and the third conveying section 4 are all changed to 50 cm / s, and the packaging carrier plate A8 continues to move forward; after the packaging carrier plate A8 completely leaves the first conveying section 2, the interval between the packaging carrier plate A8 and the packaging carrier plate B9 is 30.5 cm, and the packaging carrier plate B9 reaches the front end of the first conveying section 2;

[0034] 3) The packaging carrier plate B9 is docked with the PT pre-treatment machine and conveyed, and the packaging carrier plate A8 is continuously conveyed, specifically:

[0035] The conveying speed of the first conveying section 2 is changed to 14 cm / s, the conveying speeds of the second conveying section 3 and the third conveying section 4 are both changed to 20 cm / s; after the packaging carrier plate B9 reaches the edge between the first conveying section 2 and the second conveying section 3, the packaging carrier plate A8 has completely left the second conveying section 3 and mostly left the third conveying section 4, and the interval between the packaging carrier plate A8 and the packaging carrier plate B9 is 40.5 cm;

[0036] 4) The packaging carrier plate B9 is continuously conveyed, and the packaging carrier plate A8 is docked to the cleaning machine, specifically:

[0037] The conveying speed of the first conveying section 2 remains 14 cm / s, the conveying speed of the second conveying section 3 is changed to 14 cm / s, and the conveying speed of the third conveying section 4 remains 20 cm / s; after the packaging carrier plate A8 completely leaves the third conveying section 4, the packaging carrier plate B9 has not completely entered the first conveying section 2 and the second conveying section 3, and thus one variable-speed cross-conveying cycle ends, and the above steps can be recycled to realize continuous conveying of multiple packaging carrier plates.
