Description

Technical Field

[0001] The utility model belongs to the technical field of winding machines, and in particular relates to an automatic film winding machine. Background Art

[0002] An automatic winder is an automated device that is mainly used to regularly wind up strip or sheet materials (such as film, paper, tape, cable, etc.). The automatic winder automates the winding process and greatly reduces manual intervention. However, the winding roller on the existing automatic winder needs to be replaced and disassembled after winding the plastic film. During the replacement and disassembly process, the winding work needs to be stopped and can only be continued after the replacement and installation, thereby reducing the winding efficiency.

[0003] The Chinese patent with patent announcement number CN219156027U discloses an automatic winding machine for plastic film. The device can drive the rotating shaft to rotate through the setting of the driving component, and the rotation of the rotating shaft can drive the work frame to rotate, thereby converting the positions of the two winding rollers to meet the replacement function of different winding rollers, and the plastic film can be cut by the blade. It has good conversion function and solves the problem that the winding work needs to be stopped when the winding roller is replaced and disassembled, which affects the work efficiency. However, when the device is in use, since there are two sets of winding rollers on the work frame, when one set of winding rollers has completed winding and the other set of winding rollers is in winding work, the winding roller that has completed winding needs to be replaced. This requires multiple workers to stand by and frequently replace the winding rollers when the device is in use, resulting in a waste of workers' time.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0036] The utility model will be further explained in detail now by combining with the drawings.

[0037] Please refer to Figure 1-9As shown, in this embodiment, an automatic film winder is provided, including a base 1, two fixed plates 2 are relatively provided on the top thereof, a first rotating shaft 6 is rotatably connected between the two fixed plates 2, a plurality of connecting plates 7 are relatively fixedly connected to the first rotating shaft 6, and a winding roller 10 is rotatably connected to the two opposite connecting plates 7. A first motor 11 that drives the winding roller 10 to rotate is provided on the base 1, a control mechanism 4 that is signal-connected to the first motor 11 is provided on the fixed plate 2, and an adjustment mechanism 9 that drives the rotating shaft to rotate intermittently is provided on the fixed plate 2. The adjustment mechanism 9 includes a worm gear 91, which is sleeved on the first rotating shaft 6. Two mounting plates 99 are relatively fixedly connected to the fixed plate 2, and a worm 92 meshing with the worm gear 91 is rotatably connected to the two mounting plates 99. The worm 92 is provided with a bevel gear 1 93, and a positioning plate 96 is fixedly connected to the fixed plate 2. A third rotating shaft 95 is rotatably connected to the positioning plate 96, and the third rotating shaft 95 is provided with a bevel gear 2 94 meshing with the bevel gear 1 93. An intermittent rotating mechanism 98 is provided at one end of the third rotating shaft 95 away from the bevel gear 2 94, and a second motor 97 for driving the intermittent rotating mechanism 98 is provided on the positioning plate 96. The second motor 97 is connected to the control mechanism 4 by signal.

[0038] Specifically, when performing the winding operation, the film can be wound on the winding roller 10, and then the winding roller 10 is driven to rotate by the first motor 11 to perform the winding operation. When the winding operation of the winding roller 10 is completed, the control mechanism 4 starts the second motor 97, and the second motor 97 drives the intermittent rotation mechanism 98 to rotate an interval segment. The number of interval segments of the intermittent mechanism is the same as the number of the winding roller 10. At this time, the third rotating shaft 95 rotates, and the third rotating shaft 95 drives the bevel gear 2 94 to rotate, and the bevel gear 2 94 drives the bevel gear 1 93 to rotate, and the bevel gear 1 93 drives the worm 92 to rotate, and the worm 92 drives the worm gear 91 to rotate, and the worm gear 91 drives the first rotating shaft 6 to rotate. The intermittent rotation mechanism 98 is configured so that the plurality of winding rollers 10 will only rotate an interval segment, thereby realizing the replacement of the winding roller 10. The worker only needs to adjust the connection between the first motor 11 and the winding roller 10 to realize the winding operation of the winding roller 10. Since there are multiple winding rollers 10, the worker does not need to replace the winding roller 10 within a certain period of time, thereby saving the worker's time. The worker can use this time to deal with other work. The overall structure is simple to operate, and the number of winding rollers 10 can be changed as needed, saving the worker the time of frequently replacing the winding roller 10.

[0039] It should be noted that the intermittent rotation mechanism 98 is a structure that drives the third rotating shaft 95 to rotate intermittently. For example, the second motor 97 and the third rotating shaft 95 are connected by a connecting rod. The second motor 97 adopts a three-phase motor. The number of rotations of the third rotating shaft 95 is controlled by controlling the number of one-time rotations of the third motor, thereby realizing the control of the rotation range of the first rotating shaft 6 through the worm gear 91 and worm 92 mechanism and cooperation, so that the adjacent winding rollers 10 can be rotated to the specified position. Secondly, the self-locking property of the worm gear 91 and worm 92 can avoid the position offset of the winding roller 10 during the winding operation. Secondly, the control of the control mechanism 4 and the two motors can be realized through the numerical control technology and information technology of the existing technology, so that the rotating shaft can be automatically controlled to rotate by the control mechanism 4 within the specified time. Of course, the cutting of the film can be done manually or by the cutting mechanism of the existing technology. After the film is manually cut, it needs to be manually wound around the next winding roller 10.

[0040] In this embodiment, if Figure 7 and Figure 8 As shown, the intermittent rotation mechanism 98 includes a fixed plate 981, which is sleeved and fixedly connected to the third rotating shaft 95, and a driven plate 982 is coaxially fixedly connected to the fixed plate 981. A plurality of second interference rods 987 and a first interference rod 986 are fixedly connected to the fixed plate 981 and the driven plate 982 along their circumference direction, and a driving plate 983 is sleeved and fixedly connected to the driving shaft of the second motor 97. A shift rod 984 is coaxially fixedly connected to the driving plate 983. The shift rod 984 intermittently conflicts with the first interference rod 986. A shift groove 985 is provided through the driving plate 983. The shift groove 985 is staggered with the shift rod 984. The shift groove 985 intermittently conflicts with the second interference rod 987 shown. The diameter of the bevel gear 2 94 is larger than the diameter of the bevel gear 1 93. Specifically, when the second motor 97 rotates, the driving disk 983 rotates accordingly, and the shift rod 984 and the shift groove 985 act alternately with the corresponding first interference rod 986 and the second interference rod 987, thereby realizing intermittent rotation of the third rotating shaft 95, and then realizing intermittent rotation of the first rotating shaft 6 and the winding roller 10 through the previous transmission mechanism. The design of this intermittent rotation mechanism 98 uses a simple mechanical structure to achieve precise intermittent rotation control. Through the cooperation of the shift rod 984, the shift groove 985 and different interference rods, the intermittent movement of the winding roller 10 can be achieved in a relatively stable and adjustable manner, further ensuring the stability and operability of the winding process, helping to improve the accuracy and quality of winding, and reducing film winding defects that may be caused by irregular rotation.

[0041] In this embodiment, if Figure 4 、 Figure 5 and Figure 6As shown, a fixing column 14 and a second rotating shaft 19 are respectively provided on the two connecting plates 7 facing each other. The fixing column 14 is fixedly connected to the connecting plate 7. The second rotating shaft 19 is rotatably set on the connecting plate 7. Two insertion rods 16 are relatively fixedly connected to the winding roller 10. A socket 15 for inserting the insertion rod 16 is embedded in the fixing column 14. A mounting block 17 is fixedly connected to the second rotating shaft 19. The mounting block 17 is provided with a mounting groove 8 for inserting the insertion rod 16. A positioning hole 13 is penetrated through the insertion rod 16. A positioning bolt 21 for limiting the positioning hole 13 is movably provided on the mounting block 17. Specifically, a fixing column 14 and a second rotating shaft 19 are respectively provided on the two connecting plates 7 facing each other. The two insertion rods 16 on the winding roller 10 can be respectively inserted into the socket 15 of the fixing column 14 The locating bolt 21 is passed through the locating hole 13 on the locating rod 16 to limit the insertion rod 16, so that the winding roller 10 is stably installed between the two connecting plates 7. When the winding roller 10 needs to be replaced, the locating bolt 21 can be unscrewed and the insertion rod 16 can be removed from the insertion hole 15 and the mounting groove 8 to realize convenient disassembly of the winding roller 10. This installation and disassembly method of the winding roller 10 is relatively convenient, which is convenient for quickly replacing the winding roller 10 during the winding process, thereby improving the utilization efficiency of the equipment. At the same time, the limiting effect of the locating bolt 21 can ensure the stability of the winding roller 10 during the working process, ensure the normal development of the winding work, and reduce the problems such as uneven film winding caused by unstable installation of the winding roller 10.

[0042] In this embodiment, if Figure 6 and Figure 9 As shown, one end of the second rotating shaft 19 away from the mounting block 17 is fixedly connected to a clamping block 18 of a square structure. The base 1 is provided with a sliding mechanism 12 that drives the first motor 11 to slide toward the clamping block 18. The driving shaft of the first motor 11 is embedded with a clamping groove 20 that can be clamped with the clamping block 18. Specifically, the sliding mechanism 12 on the base 1 can drive the first motor 11 to slide toward the clamping block 18. When the clamping groove 20 on the driving shaft of the first motor 11 is clamped with the clamping block 18, the first motor 11 can drive the second rotating shaft 19 to rotate, and then drive the winding roller 10 to rotate for the winding operation. Through this clamping method, the transmission connection between the first motor 11 and the winding roller 10 is realized, which not only ensures the effective transmission of power, but also facilitates the separation operation between the motor and the winding roller 10 when needed. Secondly, the sliding mechanism 12 is a structure that drives the first motor 11 to move, which is the prior art.

[0043] In this embodiment, if Figure 1 、 Figure 2 and Figure 3As shown, two support plates 3 are relatively fixedly connected to the base 1, and two guide rollers 5 are relatively rotatably connected between the two support plates 3. A gap is defined between the guide rollers 5 for the film to pass through. The guide rollers 5 are arranged relative to the winding roller 10. Specifically, the film passes through the gap formed by the guide rollers 5 before winding. The guide rollers 5 guide and preliminarily shape the film so that it can enter the winding roller 10 more smoothly for winding. The setting of the guide rollers 5 can effectively improve the state of the film when it enters the winding roller 10, so that the film maintains a relatively flat shape before winding, and reduces the problems of wrinkles and uneven curling of the film during the winding process, thereby improving the quality of the finished film after winding, and ensuring that the film winding work can be completed efficiently and with high quality.

[0044] Working principle:

[0045] During the winding operation, the film first passes through the gap formed by the guide roller 5 before winding. The guide roller 5 guides and preliminarily shapes the film so that it can enter the winding roller 10 more smoothly for winding. After the film is wound on the winding roller 10, the first motor 11 drives the winding roller 10 to rotate for the winding operation. When the winding operation of the winding roller 10 is completed, the control mechanism 4 starts the second motor 97, and the second motor 97 drives the intermittent rotation mechanism 98 to rotate an interval segment. The number of interval segments of the intermittent mechanism is the same as the number of winding roller 10. At this time, the third rotating shaft 95 rotates, and the third rotating shaft 95 drives the bevel gear 2 94 to rotate, and the bevel gear 2 94 drives the bevel gear 1 93 to rotate, and the bevel gear 1 93 drives the worm 92 to rotate The worm 92 drives the worm gear 91 to rotate, and the worm gear 91 drives the first rotating shaft 6 to rotate, thereby realizing the rotation of the connecting plate 7 and the winding roller 10. Due to the setting of the intermittent rotation mechanism 98, multiple winding rollers 10 will only rotate an interval segment, thereby realizing the replacement of the winding roller 10. The worker only needs to adjust the connection between the first motor 11 and the winding roller 10 to realize the winding operation of the winding roller 10. Since there are multiple winding rollers 10, the worker does not need to replace the winding roller 10 within a certain period of time, thereby saving the worker's time. The worker can use this time to deal with other work. The overall structure is simple to operate, and the number of winding rollers 10 can be changed as needed, saving the worker the time of frequently replacing the winding roller 10.

[0046] The present invention is not limited to the above-described embodiments. Any structural changes made under the guidance of the present invention should be understood by anyone. Any technical solution that is the same or similar to the present invention falls within the scope of protection of the present invention. The technology, shape, and structure not described in detail in the present invention are all known technologies.
