Description

Technical Field

[0001] The invention relates to the technical field of film winding, and in particular to a protective film production winding device and a loading and unloading method which are convenient for disassembling a winding core. Background Art

[0002] In the production process of protective film, the rewinder is a key equipment, which is mainly used to wind the raw film onto the core to form the final protective film product. When unloading the core wound on the roller body, the existing rewinding machine usually rotates or moves the roller body to the front side of the equipment, and then pulls the core out of the roller body by pushing and pulling to achieve unloading. However, in some production processes, the core will not be cut before winding, so the length of the core will be longer. After the protective film is wound on the core for several turns, its weight increases significantly. When unloading the wound protective film, not only the weight of the protective film is affected, but part of the inner wall of the core contacts the surface of the roller body, and the friction between them is very large, which makes it difficult to push and pull the core to unload. In addition, in the process of unloading the core from the roller body, the roller body of the equipment needs to occupy a certain space, and the core needs to be moved out of the roller body. A certain amount of space support is also required, which results in the space occupation of the equipment taking into account the space freed up for unloading the core, which leads to a larger actual occupied space of the equipment, making the space utilization rate of the winding equipment in the production environment low. These problems limit the further improvement of the production efficiency of the protective film.

[0003] Therefore, a protective film production winding device and a loading and unloading method which are convenient for disassembling the winding core are proposed. Summary of the invention

[0011] As a preferred technical solution of the present invention, a long hole is opened on the driven gear rod and its own roller rod at the position corresponding to the air nozzle, and the air nozzle of the inflatable shaft is extended and located at the outer end of the long hole, so that inflation and deflation actions can be performed at the positions of the two frames.

[0012] A method for loading and unloading materials based on the above-mentioned production winding equipment is characterized by comprising the following steps:

[0013] S1. Winding work: The core is inserted on the rewinding roller assembly, the air shaft is ventilated to allow the convex key to protrude and clamp the core, one end of the raw film is inserted from the winding shaft and connected to the rewinding roller assembly, and then the machine is started to drive the raw film to rotate, and the driving motor is started to drive the rewinding roller assembly to rotate through the engagement with the driven gear rod, so that the raw film is wound onto the core, and the protective film product is produced after the raw film is wound on the core for several turns.

[0014] S2. Unloading work: the feeding component lifts the protective film product and maintains the height. The disassembly component on the side away from the storage component disassembles the connecting component between the air shaft and the driven gear rod, separates the rewinding roller component from the driven gear rod, and then the handling component clamps and transports the rewinding roller component. During the transportation process, when the connecting component corresponds to the disassembly component on the side close to the storage component, the transportation is temporarily stopped and the disassembly component disassembles the connecting component. Then the storage component receives the disassembled air shaft and center shaft, and stores them to the outside until the center shaft and the air shaft are separated, so that the rewinding roller component is separated outside the core, and the protective film product is also detached from the rewinding roller component. Then the feeding component drives the protective film product to descend and transports the protective film product out.

[0015] S3, loading work: the new winding core corresponds to the position of the rewinding roller assembly, the handling assembly first transports the air shaft in the reverse direction, and then the storage assembly transports the central shaft to correspond to one end of the air shaft, and the connecting assembly corresponds to the disassembly assembly, the disassembly assembly combines the connecting assembly to achieve the connection between the central shaft and the air shaft, and then repeats the above actions to connect the rewinding roller assembly into a whole state again, and finally transports it to the position of the driven gear rod corresponding to one end of the air shaft, the disassembly assembly and the connection assembly are combined to connect the rewinding roller assembly to the driven gear rod.

[0016] Compared with the prior art, the present invention can achieve the following beneficial effects:

[0017] 1. During the unloading process, the rewinding roller is disassembled from one side of the core, so that during the unloading process, the movement trajectory of the core from the equipment is from top to bottom. There is no need to change the position of the core and there is no need to pull the core out of the roller, thereby avoiding the difficulty of transporting heavy protective film products, facilitating the unloading of the core, and reducing the space occupied by the unloading operation, so that the space utilization rate of the equipment to the production environment is increased, and the equipment can be arranged more compactly and reasonably to improve production efficiency.

[0018] 2. Through the setting of the handling assembly, during production work, one end of the rewinding roller assembly is supported by clamping the swivel, so that the rewinding roller assembly can stably maintain its position to rotate and support the protective film, and save the action of fixing the rewinding roller assembly to improve efficiency. When it is necessary to unload the core wound with the protective film, the rewinding roller assembly can be directly pulled out from one side of the core. Compared with pulling the heavy protective film core, pulling out the rewinding roller assembly is more convenient and efficient, and it also avoids the problem of difficulty in unloading the protective film core due to insufficient space.

[0019] 3. Through the setting of the storage component, after the rewinding roller component is pulled out from the core, it can be disassembled and evenly distributed on one side of the equipment in the front and back states, thereby reducing the space occupied on the opposite side of the equipment and further improving the utilization rate of the equipment in the production environment space.

[0020] 4. Through the setting of the feeding assembly, the protective film is limited by lifting when the core is removed, avoiding the friction between the inner wall of the core and the rewinding roller assembly, reducing the difficulty of disassembling the rewinding roller assembly, and by driving the roller table to move, the heavy protective film assembly can be easily driven to the unloading position for convenient slitting or storage operations.

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention. The experimental methods in the following embodiments, unless otherwise specified, are conventional methods, and the materials, reagents, etc. used in the following embodiments, unless otherwise specified, can be obtained from commercial channels.

[0030] Embodiment: Figure 1-7 As shown, a protective film production winding device that is easy to disassemble the winding core includes a machine table 10, and a control circuit and a driving device are arranged in the machine table 10. The machine table 10 is a well-known technology and will not be described in detail here. A plurality of winding shafts 11 are installed on the machine table 10. The arrangement and installation method of the winding shafts 11 are well-known technologies and will not be described in detail here. Both ends of the front side of the machine table 10 are connected with frame plates 12, which are characterized in that a rewinding roller assembly is rotatably installed on the two frame plates 12, and the rewinding roller assembly includes a central shaft 15 and an air shaft 16. The air shaft 16 adopts a key-type air shaft. The number of the air shafts 16 is two and they are distributed at both ends of the central shaft 15. The central shaft 15 and the air shaft 16 are provided with connecting components that can realize the disassembly function, and the central shaft 15 and the air shaft 16 are connected by The components are connected, and both frame plates 12 are provided with disassembly and assembly components for disassembling and assembling the connection components. The frame plate 12 on one side is also provided with a handling component for clamping and conveying the rewinding roller component. The frame plate 12 on the side away from the drive motor 13 is provided with a storage component for receiving and storing the central axis 15 and the air shaft 16. In addition, a feeding component for lifting and supporting the winding core is also provided below the rewinding roller assembly. A drive motor 13 is installed on the frame plate 12 on one side, and a driven gear rod 14 is rotatably installed on the frame plate 12 corresponding to the drive motor 13. The driven gear rod 14 is connected to the air shaft 16 at the corresponding position through a connecting component, and the driven gear rod 14 is meshed with the driving gear on the drive motor 13, and the driving gear is connected to the transmission shaft of the drive motor 13.

[0031] like Figure 1 and Figure 2As shown, the connecting assembly includes a sleeve 17, the number of which is three and is respectively connected to the end of the driven gear rod 14, the end of the air shaft 16 corresponding to the driven gear rod 14 and the end of the central shaft 15 close to the driven gear rod 14, and the ends of the central shaft 15 and the air shaft 16 corresponding to the sleeve 17 are connected with a sleeve 18, the sleeve 18 is sleeved in the sleeve 17, a plurality of slots 19 are provided on the sleeve 18, and a socket 20 is provided on the sleeve 17 at the position corresponding to the slot 19, and a snap-fit ​​key is sleeved on the socket 20 21, the shape and size of the engaging key 21 are adapted to the slot 19, one side of the slot 19 is provided with an inclined cut, and the engaging key 21 is provided with an inclined cut on the opposite side of the cut. The engaging key 21 is T-shaped and has a hole at one end, and a tension bolt 22 is inserted into the hole. A threaded hole is provided at a position corresponding to the tension bolt 22 on the sleeve 17 and is threadedly connected to the tension bolt 22. A guide rod 23 is also connected to one end of the engaging key 21, and a sliding hole is provided at a position corresponding to the guide rod 23 on the sleeve 17 and is inserted into the guide rod 23.

[0032] Specifically, when the sleeve 18 is inserted into the sleeve 17, the end of the sleeve 18 first contacts the cut surface of the tension bolt 22, and the tension bolt 22 is pushed by the cut surface to slide toward the outside of the sleeve 17, thereby avoiding contact with the sleeve 18 and causing it to get stuck. Similarly, when the sleeve 18 is pulled out of the sleeve 17, the cross section of the groove 19 generates a thrust on the engaging key 21 to make it separate from the groove 19. After the sleeve 18 is inserted into the sleeve 17, the tension bolt 22 is rotated to push the engaging key 21. Slide into the socket 20 so that the locking key 21 is inserted into the slot 19, thereby connecting the sleeve 17 and the sleeve shaft 18, and allowing the driven gear rod 14, the central shaft 15 and the inflatable shaft 16 to form a roller body. When the protective film is wound, gravity will act on the sleeve 17 and the sleeve shaft 18, and the rotational force will act on the sleeve 17, the sleeve shaft 18 and the locking key 21. By selecting materials with sufficient hardness for the sleeve 17, the sleeve shaft 18 and the locking key 21, their bearing capacity can be guaranteed.

[0033] like Figure 1 and Figure 3As shown, the disassembly and assembly component includes an annular frame 24, which is connected to the frame plate 12. A side of the annular frame 24 corresponding to the rewinding roller assembly is connected to a plurality of fixed frames 25 in an annular shape. The number and position of the fixed frames 25 correspond to the engaging key 21. A lifting device 26 is installed on the fixed frame 25. The lifting device 26 adopts a telescopic cylinder. The transmission shaft of the lifting device 26 corresponds to the center of the annular frame 24 and is connected to a lifting frame 27. A disassembly and assembly motor 28 is installed on the lifting frame 27. The transmission shaft of the disassembly and assembly motor 28 passes through the lifting frame 27 and is connected to a main shaft 29. A sliding sleeve 30 is sleeved on the main shaft 29. A sliding key (not shown in the figure) is connected to the inner wall of the sliding sleeve 30. A groove for the sliding key to be sleeved and slide is opened on the main shaft 29. A disc is connected to the bottom end of the sliding sleeve 30, and a hexagonal protrusion is provided on the bottom surface of the disc. A resistance spring 31 is sleeved on the outside of the sliding sleeve 30, and the two ends of the resistance spring 31 are respectively in resistance to the disc and the lifting frame 27.

[0034] Specifically, when disassembling the connection assembly, the driven motor 13 drives the driven gear rod 14 to rotate, so that the position of the tension bolt 22 corresponds to the sliding sleeve 30, and then the transmission shaft of the lifting device 26 extends to insert the hexagonal protrusion on the sliding sleeve 30 into the tension bolt 22, and then the disassembly motor 28 drives the main shaft 29 to rotate, and the main shaft 29 drives the sliding sleeve 30 to rotate through the insertion of the groove on the main shaft 29 and the sliding key on the sliding sleeve 30, and the sliding sleeve 30 drives the tension bolt 22 to rotate, and the tension bolt 22 gradually moves out of the sleeve 1 during the rotation process. 7, at this time, the sliding sleeve 30 extends out in accordance with the tension bolt 22 by sliding the sliding key in the groove on the main shaft 29. Conversely, when the connecting components are assembled, the sliding sleeve 30 will first compress the resistance spring 31 when inserted into the tension bolt 22. Then, when the tension bolt 22 is gradually inserted into the sleeve 17, the resistance spring 31 releases energy and rebounds to keep the sliding sleeve 30 in resistance against the tension bolt 22, thereby screwing the tension bolt 22 into the sleeve 17. After the connecting components are disassembled and assembled, the transmission shaft of the lifting device 26 retracts to drive the lifting frame 27 to reset.

[0035] like Figure 1 and Figure 4As shown, the transport assembly includes a gantry 32, which is connected to the top of the frame plate 12. A clamping frame 33 is arranged on the gantry 32, and two transmission frames 34 are arranged on the clamping frame 33. A rectangular hole is opened on the front of the clamping frame 33, and a convex plate is connected to a side of the transmission frame 34 corresponding to the rectangular hole. A screw is rotatably connected to the clamping frame 33, and the screw is threadedly connected to the convex plate. The clamping frame 33 is U-shaped and the concave surfaces of the two clamping frames 33 correspond to each other. A conveyor belt 35 is rotatably installed inside the clamping frame 33. The conveyor belt 35 adopts a toothed conveyor belt, and a motor for driving the conveyor belt 35 is installed on the clamping frame 33. The installation and operation of the conveyor belt 35 are existing well-known technologies and are not described in detail here. The conveyor belt 35 is connected to a plurality of convex plates for clamping. The convex plates are made of materials with certain friction such as rubber, plastic or metal with patterns on the surface. A curved groove is opened on the surface of the convex plate. The convex plates on the two conveyor belts 35 clamp a swivel 36, and the center of the swivel 36 is connected to the left end of the rewinding roller assembly through a rotating bearing.

[0036] Specifically, by clamping the swivel 36 through the conveyor belt 35, the conveyor belt 35 lifts one end of the rewinding roller assembly, thereby providing support for the end of the rewinding roller assembly away from the driven gear rod 14, allowing the rewinding roller assembly to rotate more stably and support the protective film. During the unloading work, the motor drives the conveyor belt 35 to operate, and the conveyor belt 35 transports the rewinding roller assembly through the clamping operation, so that the rewinding roller assembly can pull out the core or insert the core.

[0037] like Figure 1 and Figure 5 As shown, the storage assembly includes a storage table 37, which is connected to the shelf plate 12 near the side of the clamping frame 33, and a sliding screw 38 is rotatably connected to the storage table 37. A positioning motor 39 for driving the sliding screw 38 is installed on the storage table 37, and a slide 40 is threadedly connected to the sliding screw 38. The storage table 37 is connected to a guide rail, and a slide seat connected to the slide 40 is slidably installed on the guide rail. The slide 40 is connected to two placement racks 41, and the placement racks 41 are connected to two transmission frames 42 that are opposed to each other up and down. The transmission frame 42 is U-shaped and the concave surfaces correspond to each other. A conveyor belt 43 is installed in the transmission frame 42. The connection between the conveyor belt 43 and the connection conveyor belt 1 35 of the transmission frame 42 is consistent with that on the transmission frame 1 34. The conveyor belt 43 is also connected to a number of convex plates, and a motor for driving the conveyor belt 43 to operate is installed on the transmission frame 42.

[0038] Specifically, when the handling assembly clamps and conveys the rewinding roller assembly, the conveyor belt 2 43 receives the rewinding roller assembly from one side and clamps and conveys it synchronously. Then, when the connecting assembly is conveyed to the corresponding disassembly assembly, the conveying is stopped at this time, and the disassembly assembly removes the inflatable shaft 16 on the rewinding roller assembly. The conveyor belt 2 43 drives the inflatable shaft 16 to be further conveyed until it is separated from the inner ring of the annular frame 24. Then, the positioning motor 39 is started to drive the sliding screw 38 to rotate, and the slide 40 slides on the slide 40 as the sliding screw 38 rotates, thereby The disassembled inflatable shaft 16 is taken away, and another set of transmission frame 2 42 and conveyor belt 2 43 are moved to the position corresponding to the inner circle of the annular frame 24, and then the above-mentioned action is repeated until the central shaft 15 is received and taken away, and then the central shaft 15 and the inflatable shaft 16 are respectively clamped between the two sets of conveyor belts 2 43 and conveyor belt 1 35, so that the rewinding roller assembly is removed from the core, and when the central shaft 15 and the inflatable shaft 16 are connected, the above-mentioned action is repeated for reverse transportation, and when the connecting component corresponds to the disassembling component, wait for connection.

[0039] like Figure 1 and Figure 6 As shown, the feeding assembly includes a roller table 44, which is arranged below the rewinding roller assembly. A lockable universal wheel is installed on the roller table 44. A hydraulic cylinder 45 is installed on the top surface of the roller table 44. The transmission shaft of the hydraulic cylinder 45 is connected to a lifting frame 46. The top surface of the lifting frame 46 is concave and grooved on both sides. A limit plate 47 is inserted in the groove. A plurality of circular grooves are opened in the center of the lifting frame 46, and a ball 48 is rotatably installed in the circular groove.

[0040] It should be noted that the structural movement limit of the present application can be detected and controlled by setting up sensors, which is a well-known technology and will not be elaborated here.

[0041] Specifically, when removing the winding core, the hydraulic cylinder 45 pushes the lifting frame 46 to lift up to resist the protective film, thereby limiting the protective film, avoiding friction between the inner wall of the winding core and the rewinding roller assembly, and reducing the difficulty of disassembling the rewinding roller assembly. After the rewinding roller assembly is pulled out of the winding core, the hydraulic cylinder 45 drives the protective film product to descend, expands the front space of the rewinding roller assembly, and then releases the limit of the universal wheel and pulls out the roller table 44, which can drive the roller table 44 to move to transfer the protective film to the unloading position, and then pull out the limiting plate 47 on one side, and conveniently push out the protective film product through the rotation of the ball 48, so as to facilitate operations such as slitting or storage.

[0042] like Figure 7 As shown, a long hole is opened on the driven gear rod 14 and its own roller rod at the position corresponding to the air nozzle, and the air nozzle of the air expansion shaft 16 is extended and located at the outer end of the long hole, so that inflation and deflation can be performed at the positions of the two frame plates 12.

[0043] A method for loading and unloading protective film production winding equipment that is easy to disassemble the winding core includes the following steps: first, the winding work is performed, the winding core is inserted into the rewinding roller assembly, the air expansion shaft 16 is ventilated to allow the convex key to protrude to tighten the winding core, one end of the raw material film is inserted from the winding shaft 11 and connected to the rewinding roller assembly, then the machine 10 is started to drive the raw material film to rotate, the driving motor 13 is started to drive the rewinding roller assembly to rotate through engagement with the driven gear rod 14, so that the raw material film is wound onto the winding core, and the protective film product is produced after the raw material film is wound on the winding core for several turns. After the protective film product is produced, the driving motor 13 stops the rotation of the rewinding roller assembly, and the winding work stops at this time. The feeding assembly lifts the protective film product and maintains the height. The disassembly assembly on the side away from the storage assembly disassembles the connecting assembly between the air shaft 16 and the driven gear rod 14, and the rewinding roller assembly is separated from the driven gear rod 14. Then the conveying assembly clamps and conveys the rewinding roller assembly. During the conveying process, when the connecting assembly corresponds to the disassembly assembly on the side close to the storage assembly, the conveying is temporarily stopped and the disassembly assembly is allowed to disassemble the connecting assembly, and then the storage assembly is The component receives the disassembled air shaft 16 or center shaft 15 and stores it outside until the center shaft 15 and the air shaft 16 are separated, so that the rewinding roller assembly is separated outside the core, and the protective film product is also separated from the rewinding roller assembly. Then the feeding component drives the protective film product to descend. After the protective film product is transported out, a new core is placed on the feeding component. The feeding component lifts the new core, or manually places it so that the new core corresponds to the position of the rewinding roller assembly. The handling component first reversely transports the air shaft 16, and then stores it. The release assembly transports the central shaft 15 to the corresponding end of the inflatable shaft 16, and makes the connecting assembly correspond to the disassembly assembly. The disassembly assembly combines the connecting assembly to realize the connection between the central shaft 15 and the inflatable shaft 16, and then repeats the above actions to connect the rewinding roller assembly into a whole state again. Finally, it is transported to the position corresponding to the driven gear rod 14 at one end of the inflatable shaft 16, and the disassembly assembly and assembly assembly are combined with the connecting assembly to connect the rewinding roller assembly to the driven gear rod 14, so that the rewinding roller is installed in the winding core, and the feeding assembly is reset to perform the winding work again.

[0044] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
