Description

Technical Field

[0001] The invention relates to the technical field of cargo packaging, and in particular to a film winding machine. Background Art

[0002] After the product (such as beverage) is produced, boxed and palletized, it needs to be wrapped and bundled with film for transportation. The film has a buffering effect and can also prevent the goods from collapsing or falling during transportation and causing damage to the goods. The existing film wrapping is achieved by a mechanical arm, one end of which rotates around a pivot point set above the palletized goods, thereby forming a circular path around the palletized goods. At the opposite end, the mechanical arm is connected to a vertically extending column, which supports a vertically movable reel. When the reel follows the circular path and moves vertically along the column, the reel unwinds and distributes the film to package the palletized goods.

[0003] However, after the film packaging is completed and cut, the tail end of the film wrapped around the stacked goods will fly around. The current way to solve this problem is to use a heating plate to heat the tail end of the film on the inner film, but this method is not suitable for bagged products and it is easy to burn the packaging bag of the bagged products; the second is to use a brush to brush the surface of the inner film to generate static electricity on its surface, so that the tail end of the film can be attached, but this method cannot keep the tail end of the film attached for a long time and the attachment effect is poor.

[0004] Therefore, the present application provides a film winding machine to solve the above problems. Summary of the invention

[0008] Furthermore, the film extension assembly also includes an extension drive, a main extension gear is fixedly arranged at the driving end of the extension drive, a pinion 1 and a pinion 2 are sequentially arranged along the height direction of the end of the rubber-coated roller 1 close to the extension drive, a slave extension gear is fixedly arranged at the end of the rubber-coated roller 2 close to the extension drive, and the main extension gear and the pinion 1, the pinion 2 and the slave extension gear are connected respectively through a transmission chain.

[0009] Furthermore, the film sealing mechanism also includes a film sealing support, a plate lifting assembly, and a film sealing lifting module vertically arranged on the film sealing support, and the plate lifting assembly is located on the film sealing lifting module and can move up and down driven by the film sealing lifting module. The film sealing support provides support for the film sealing lifting module, the plate lifting assembly, and the film cutting assembly; the film sealing lifting module can adjust the position of the plate lifting assembly in the height direction, so that the film sealing mechanism is suitable for stacking goods at different heights, thereby improving the applicability of the present invention.

[0014] Furthermore, a connecting block is provided at the top of the piston rod of the film pressing cylinder, and the heating block and the connecting block are connected via a buffer spring. The buffer spring can effectively prevent the heating block from directly hitting the abutment plate and causing damage to the abutment plate.

[0015] Furthermore, the outer cover of the film supply assembly is provided with a protective shell, which will not interfere with the feeding, extension and conveying of the film, and can protect the extension main gear, two pinions and the extension slave gear.

[0019] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0020] See attached Figures 1 to 6 As shown, a film winding machine in this embodiment includes a film coating mechanism 2 and a film sealing mechanism 3; the film coating mechanism 2 includes a rotating frame 21 and a film supply component 24, the rotating frame 21 can drive the film supply component 24 to make a circular motion on a horizontal plane to wrap the film around the stacked goods, the film supply component 24 continuously provides film for the winding of the stacked goods, the rotating frame 21 drives the film supply component 24 to rotate to automatically realize the winding of the stacked goods, without the need for manual winding and packaging, which can effectively reduce the labor intensity of the staff and improve the packaging efficiency of the stacked goods.

[0021] The film supply component 24 includes a film stretching component 244 for stretching the film, and the film stretching component 244 includes a rubber-coated roller 1 2445 and a rubber-coated roller 2447 which are arranged in parallel with each other. A limited space for the film to pass through is reserved between the rubber-coated roller 1 2445 and the rubber-coated roller 2 2447, and there is a speed difference between the two. After the film is pulled out from its output end, it passes between the rubber-coated roller 1 2445 and the rubber-coated roller 2 2447 in an S shape and is in a tensioned state. During the process of film wrapping around the stacked goods, the rubber-coated roller 1 2445 and the rubber-coated roller 2 2447 rotate at different speeds under the action of the driving member, that is, the rotation of the rubber-coated roller 1 2445 and the rubber-coated roller 2 2447 produces a speed difference, and the speed difference can extend the length of the film, thereby reducing the amount of film used in the subsequent winding process and reducing the packaging cost of the enterprise.

[0022] In some embodiments, see Appendix Figures 2 to 4 The film extension assembly 244 also includes an extension drive member 2441, a main extension gear 2442 is fixedly arranged at the driving end of the extension drive member 2441, a pinion 2443 and a second pinion 2444 are sequentially arranged along the height direction of the end of the rubber-coated roller 1 2445 close to the extension drive member 2441, and an extension slave gear 2446 is fixedly arranged at the end of the rubber-coated roller 2447 close to the extension drive member 2441, and the main extension gear 2442 and the pinion 1 2443, the pinion 2444 and the extension slave gear 2446 are connected respectively through a transmission chain. The transmission between the main extension gear 2442 and the rubber-coated roller 1 2445, and between the rubber-coated roller 2 2447 and the rubber-coated roller 1 2445 is realized through an extension drive member 2441.

[0023] When the extension driving member 2441 drives the extension main gear 2442 to rotate, the pinion 1 2443 connected to it through the transmission chain can drive the rubber coating roller 1 2445 to rotate, that is, the pinion 2 2444 fixed thereon rotates, and the pinion 2 2444 is connected to the extension slave gear 2446 through the transmission chain, and then the rubber coating roller 2 2447 fixedly connected to the extension slave gear 2446 also rotates accordingly, and the above gear transmission makes the rotation of the rubber coating roller 1 2445 and the rubber coating roller 2 2447 produce a reduction ratio to achieve the stretching of the film. Specifically, the stretching ratio of the film is 1:3, which can effectively reduce the total amount of film winding.

[0024] The upper and lower ends of the rubber-coated roller 1 2445 and the rubber-coated roller 2 2447 are rotatably connected to the top and bottom of the protective shell 242 through bearings, so that when the extension driving member 2441 drives the extension main gear 2442 to rotate, the rubber-coated roller 1 2445 and the rubber-coated roller 2 2447 can also rotate accordingly to stretch the film passing through them.

[0025] In some embodiments, the extension driving member 2441 is an extension driving motor or other known mechanical structures capable of driving the extension main gear 2442 to rotate, such as a reducer or a dividing plate.

[0026] The film sealing mechanism 3 includes a liftable abutment plate 33 and a film cutting assembly 35, wherein the film cutting assembly 35 includes a heating block 359 that can press at least two layers of film onto the abutment plate 33 and a heating wire 358 for cutting the film. The heating block 359 can heat-form the multiple layers of film together, so that after the film is cut by the heating wire 358, the tail end of the film can be firmly fixed on the inner film to prevent the tail end of the film from flying around.

[0027] Specifically, the film cutting component 35 is arranged on the side of the stacked goods and is arranged close to it. When the film is wrapped around the stacked goods, the abutment plate 33 will rise after the initial few turns of wrapping, and then the film continues to wrap around the stacked goods. At this time, the abutment plate 33 is clamped between the inner and outer parts of the film, so that the subsequent heating block 359 can heat the tail end of the outermost film on the inner film close to the outer surface of the abutment plate 33 after heating, thereby achieving fixed adsorption of the tail end of the film and avoiding the phenomenon of the tail end flying around after the heating wire 358 cuts off the film.

[0028] It should be noted that the film located outside the abutment plate 33 is wrapped with at least two layers to ensure that the outermost film can be thermoplastically fixed to the film in the outer part close to the abutment plate 33; the outer surface of the abutment plate 33 refers to the side away from the stacked goods.

[0029] The film supply assembly 24 is connected to the vertical swing arm on the rotating frame 21 via the connecting base 241 and can be lifted and lowered. The film supply assembly 24 also includes a film unwinding frame 243 arranged parallel to the rubber coating roller 2445. The film wound in a cylindrical shape is sleeved on the film unwinding frame 243, which is convenient for film feeding to wrap the stacked goods. At the same time, during the rotation of the rotating frame 21, the film supply assembly 24 can move up and down, so that the film can completely wrap the stacked goods along the height direction, ensuring that the stacked goods will not collapse or fall during the subsequent transportation process.

[0030] In some embodiments, a movable guide rail is provided on the vertical swing arm along its height direction to guide the lifting and lowering of the film extension assembly 244. Transmission gears are provided at the upper and lower ends of the movable guide rail respectively. The two transmission gears are connected by a transmission chain. When the transmission motor drives one of the transmission gears to rotate, the transmission chain can drive the connecting base 241 fixedly connected to at least one section thereof to move up and down, so as to realize the position movement of the film supply assembly 24 in the height direction.

[0031] In other embodiments, a linear module can be set along the height direction of the vertical swing arm, and the connecting base 241 can be set on the linear module. During the rotation of the rotating frame 21, the linear module can also drive the film supply assembly 24 to move upward or downward synchronously to completely wrap the stacked goods in its height direction.

[0032] The film sealing mechanism 3 further comprises a film sealing support 31, a plate lifting assembly 34 and a film sealing lifting module 32 vertically arranged on the film sealing support 31. The plate lifting assembly 34 is located on the film sealing lifting module 32 and can move up and down driven by the film sealing lifting module 32. The film sealing support 31 provides support for the film sealing lifting module 32, the plate lifting assembly 34 and the film cutting assembly 35; the film sealing lifting module 32 can adjust the position of the plate lifting assembly 34 in the height direction, so that the film sealing mechanism 3 is suitable for palletizing goods at different heights, thereby improving the applicability of the present invention.

[0033] In some embodiments, the plate lifting assembly 34 includes a mounting seat 341, and a plate lifting guide rail 342 is arranged on the mounting seat 341 along its height direction. The back of the abutment plate 33 is slidably connected to the plate lifting guide rail 342 through a slider. The lifting guide rail can provide guidance for the up and down movement of the abutment plate 33. Specifically, the back of the abutment plate 33 is the side away from the stacked goods.

[0034] The mounting seat 341 is provided with a plate lifting cylinder 343 parallel to the plate lifting guide rail 342, and the driving end of the plate lifting cylinder 343 is fixedly connected to the abutment plate 33. The extension and retraction of the piston rod of the plate lifting cylinder 343 can drive the abutment plate 33 to move upward or downward along the plate lifting guide rail 342 to adjust the corresponding position of the abutment plate 33 and the tail end of the film, so that the abutment plate 33 can completely cover the tail end of the film in the height direction, so as to ensure the efficiency of subsequent film cutting and hot stamping.

[0035] The film cutting assembly 35 is rotatably arranged on the back of the film sealing bracket 31 through a rotating assembly, and the rotating assembly includes a rotating cylinder 351. The telescopic end of the rotating cylinder 351 is connected to the rotating member 352 through a rotating hinge seat 353, and the film cutting assembly 35 is fixed on the rotating hinge seat 353. The piston rod end of the rotating driving cylinder is hinged to the rotating hinge seat 353. When the piston rod of the rotating driving cylinder is extended, it can push the end of the rotating hinge seat 353 that is hinged to it to rotate a certain angle along the rotating member 352.

[0036] In some embodiments, when the film cutting assembly 35 is not working, it is in a horizontal state as a whole and will not interfere with the film when it is wrapped around the stacked goods; when the film is wrapped, when the film needs to be cut or melted, the piston rod of the rotating cylinder 351 extends to push the rotating hinge seat 353 to rotate 90 degrees, so that the film cutting assembly 35 is rotated as a whole from a horizontal state to a vertical state corresponding to the abutment plate 33, so as to cut or melt the film on the abutment plate 33.

[0037] The film cutting assembly 35 includes a mounting frame 354, the heating wire 358 is arranged on the mounting frame 354 along the length direction thereof, and a film pressing cylinder 360 is arranged below the mounting frame 354, and the heating block 359 is located at the top of the piston rod of the film pressing cylinder 360. The length direction of the heating block 359 is parallel to the length direction of the heating wire 358, and when the film pressing cylinder 360 pushes the heating block 359 to move toward the abutment plate 33, it will not interfere with the heating wire 358, that is, the setting of the heating block 359 will not affect the cutting of the film by the heating wire 358.

[0038] Specifically, after the film is wound, the piston rod of the film pressing cylinder 360 extends, pushing the heating block 359 to move toward the abutment plate 33 and pressing the film outside the abutment plate 33 onto the abutment plate 33. At this time, the heating wire 358 heats and cuts the film at the corresponding position. During the cutting process, the heating block 359 gradually heats up, and can melt the tail end of the film wound on the stacked goods onto the inner film at the same time, thereby fixing the tail end of the film. After the above-mentioned film cutting is completed, the abutment plate 33 moves downward to reset and detach from the film, and the film cutting assembly 35 is also reset under the action of the rotating assembly, which also saves the overall space occupied by the film sealing mechanism 3 and does not interfere with the film winding of the next stacked goods.

[0039] It should be noted that the length of the heating wire 358 at least covers the height of the film to ensure that the film can be completely cut.

[0040] In some embodiments, a mounting plate parallel to the mounting frame 354 is disposed at the top of the piston rod of the film pressing cylinder 360, and two or three heating blocks 359 are disposed on the mounting plate at intervals along its length. When the piston rod of the film pressing cylinder 360 is extended, the two or three heating blocks 359 on the mounting plate can be pushed to move toward the direction close to the abutment plate 33, and the film located outside the abutment plate 33 can be pressed against the abutment plate 33. The provision of multiple heating blocks 359 can ensure the melting efficiency of the tail end of the film, and avoid the phenomenon that the tail end is not melted and flies around due to a part of it not being melted.

[0041] The film cutting assembly 35 includes a connecting piece 355 fixed on a rotating hinge seat 353, an end of the mounting frame 354 close to the rotating piece 352 is connected to an end of the connecting piece 355 close to the rotating hinge seat 353, an end of the connecting piece 355 away from the rotating hinge seat 353 is hinged with a supporting cylinder 357 through a rotating hinge seat 356, and the top end of the piston rod of the supporting cylinder 357 is hinged to the mounting frame 354.

[0042] Specifically, the horizontal plane where the length direction of the piston rod of the support cylinder 357 is located is parallel to the horizontal plane where the length direction of the mounting frame 354 is located. The piston rod of the support cylinder 357 is hinged to the middle part of the side of the mounting frame 354 away from the abutment plate 33 to ensure the stability of the subsequent mounting frame 354 when rotating or supporting the heating wire 358 and the heating block 359 thereon.

[0043] The piston rod of the supporting cylinder 357 extends out to support the mounting frame 354 from the side of the mounting frame 354 away from the abutment plate 33, thereby preventing the mounting frame 354 from tipping over during subsequent cutting and melting of the film, thereby affecting the film cutting efficiency.

[0044] A connecting block is provided at the top of the piston rod of the film pressing cylinder 360, and the heating block 359 is connected to the connecting block via a buffer spring. The buffer spring can effectively prevent the heating block 359 from directly hitting the abutment plate 33 and causing damage to the abutment plate 33.

[0045] The outer cover of the film supply assembly 24 is provided with a protective housing 242. The protective housing 242 will not interfere with the feeding, extension and conveying of the film, and its setting can protect the extension main gear 2442, two pinions and the extension slave gear 2446.

[0046] It also includes a gantry 1, a horizontal swing arm on the rotating frame 21 is rotatably connected to the top of the gantry 1 through a rotating toothed disc 22, and a rotating drive motor 23 is also provided on the gantry 1, and a rotating gear meshing with the rotating toothed disc 22 is fixedly connected to the driving end of the rotating drive motor 23. When the rotating drive motor 23 drives the rotating gear to rotate, it can drive the rotating toothed disc 22 to rotate, and then drive the entire rotating frame 21 to rotate with the rotating toothed disc 22 as the axis, so that the film on the rotating frame 21 can rotate and wrap around the stacked goods.

[0047] The above implementation modes are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
