The entire tape winding process is cumbersome, which affects the winding speed. Summary of the invention

[0005] In order to increase the winding speed, the present application provides a bubble film production device and a method thereof.

Figure 1 The bubble film production equipment includes a body 1 of a bubble film machine, a material receiving side of the body 1 is rotatably connected to a winding roller 2, a plurality of paper tubes are sleeved on the outer peripheral side of the winding roller 2, and the length of the paper tube is shorter than the required width of the bubble film. When receiving the material, the body 1 drives the winding roller 2 to rotate so that the bubble film is wrapped around the outer peripheral side of the paper tube.

[0047] See also Figure 2 , a receiving groove 4 is provided on the outer circumference of the winding roller 2, and the receiving groove 4 is located between two adjacent paper tubes. The winding roller 2 is rotatably connected to a winding roller 41, and the winding roller 41 is located in the receiving groove 4. A tape 42 is wound on the outer circumference of the winding roller 41, and the winding roller 41 can be disassembled and removed, so as to facilitate the addition of the tape 42. A mounting groove 3 is provided on the outer circumference of the winding roller 2, and the mounting groove 3 is located between two adjacent paper tubes. The receiving groove 4 corresponds to the mounting groove 3 one by one and is arranged at intervals along the circumferential direction. The winding roller 2 is provided with a through hole 21, and the through hole 21 is connected to the mounting groove 3 and the receiving groove 4 respectively. After the tape 42 slides through the through hole 21, it extends into the mounting groove 3. At this time, the adhesive surface of the tape 42 is facing away from the central axis of the winding roller 2. At the same time, when the tape 42 slides through the through hole 21, the adhesive surface of the tape 42 is at a certain distance from the hole wall of the through hole 21.

[0048] See also Figure 2The outer circumference of the winding roller 2 is provided with a receiving groove 5, which corresponds to the mounting groove 3 one by one and is arranged at intervals along the circumferential direction, and the mounting groove 3 is located between the receiving groove 5 and the receiving groove 4. A connecting hole 22 is provided in the winding roller 2, and the two sides of the connecting hole 22 are connected to the mounting groove 3 and the receiving groove 5 respectively. The adhesive tape 42 in the mounting groove 3 slides through the connecting hole 22 and extends into the receiving groove 5, and the adhesive surface of the adhesive tape 42 is spaced from the hole wall of the connecting hole 22.

[0049] See also Figure 3 and Figure 4 A guide groove 2112 is provided in the winding roller 2. The guide groove 2112 is connected to the through hole 21 and extends toward the central axis of the winding roller 2. The winding roller 2 is provided with a segmentation knife 211, and the segmentation knife 211 is slidably connected to the guide groove 2112. There are two segmentation knives 211 and they are symmetrically arranged along the central axis of the winding roller 2. A linkage bar 2113 is fixedly connected between the two segmentation knives 211, so that the two segmentation knives 211 can be linked. The winding roller 2 is provided with a driving spring 2111. There are multiple driving springs 2111 and they are located in the guide groove 2112. One end of the driving spring 2111 abuts against the side of the linkage bar 2113 facing away from the segmentation knife 211, and the other end abuts against the groove wall of the guide groove 2112. When in use, the driving spring 2111 is elastically released to push the segmentation knife 211 to slide and protrude into the through hole 21. The blade of the splitting knife 211 faces the winding roller 41. When the tape 42 slides toward the mounting groove 3, the splitting knife 211 splits the tape 42 so that the tape 42 is divided into three sections, and the width of a section of the tape 42 between the two splitting knives 211 is much larger than the width of the tapes 42 on both sides.

[0050] See also Figure 4 and Figure 5 The winding roller 2 is provided with a support plate 31, which is located in the mounting groove 3 and can slide toward or away from the central axis of the winding roller 2. A driving groove 23 is provided in the winding roller 2, which passes through the end to the outside, and the winding roller 2 is provided with a driving column 6 slidably connected to the driving groove 23. There is a certain friction between the driving column 6 and the driving groove 23. When the winding roller 2 rotates, the possibility of the driving column 6 sliding out of the driving groove 23 is reduced. The winding roller 2 is provided with a transmission component 7. When the driving column 6 slides into the driving groove 23, the transmission component 7 transmits power to drive the support plate 31 to move out of the mounting groove 3. At this time, the support plate 31 drives a section of the tape 42 between the two dividing knives 211 to move to the outside of the mounting groove 3 until the adhesive surface of the tape 42 is flush with the outer peripheral side of the paper tube, so that when the winding roller 2 rotates, the bubble film can be bonded to the adhesive surface of the tape 42 and thus wrapped around the outer peripheral side of the paper tube. When the driving column 6 slides out of the driving slot 23 , the transmission assembly 7 transmits power to move the support plate 31 into the installation slot 3 until the support plate 31 returns to its original position.

[0051] See also Figure 4 and Figure 5 The transmission assembly 7 includes a transmission block 72 and a transmission column 71. A transmission hole 711 is provided in the winding roller 2. The two sides of the transmission hole 711 are connected to the mounting groove 3 and the driving groove 23 respectively. The transmission column 71 is slidably connected to the transmission hole 711 and its two ends protrude into the mounting groove 3 and the driving groove 23 respectively. The support plate 31 is fixed to the end of the transmission column 71 away from the driving groove 23. The transmission block 72 is fixed to the outer peripheral side of the driving column 6 and corresponds to the transmission column 71. The peripheral groove wall of the driving groove 23 is connected to the movable groove 231, and the transmission block 72 slides in the movable groove 231. The transmission block 72 is inclined to open a transmission surface 721 on one side of the notch of the driving groove 23. When the driving column 6 slides into the driving groove 23, the transmission column 71 slides on the transmission surface 721. At this time, the transmission column 71 is pushed toward the mounting groove 3 by the transmission block 72 until the transmission column 71 abuts against the end of the transmission block 72 facing away from the driving column 6. The support plate 31 drives the tape 42 until the adhesive surface is flush with the outer peripheral side of the paper tube.

[0052] See also Figure 4 and Figure 5 The winding roller 2 is provided with an elastic power member, which is a power tension spring 311. The power tension spring 311 is provided in the mounting groove 3. One end of the power tension spring 311 is connected and fixed to the side wall of the support plate 31 facing away from the groove of the mounting groove 3, and the other end is fixed to the groove wall of the mounting groove 3 away from the groove. When the driving column 6 slides outward from the driving groove 23, the driving column 6 gradually separates from the transmission block 72. At this time, the power tension spring 311 is elastically released, pulling the support plate 31 to slide into the mounting groove 3.

[0053] See also Figure 4 and Figure 5 The winding roller 2 has two symmetrically arranged connecting grooves 242, which are respectively connected to the through hole 21 and the connecting hole 22 (the connecting hole 22 is Figure 2 ), one side of the two connecting grooves 242 is connected to the driving groove 23, and the other side is connected to the corresponding through hole 21 or the connecting hole 22. The winding roller 2 is symmetrically provided with two cutting knives 24, which correspond to the connecting grooves 242 one by one and are arranged in the connecting grooves 242. The cutting knives 24 can slide toward or away from the central axis of the winding roller 2. When in use, the cutting knives 24 are used to cut a section of the adhesive tape 42 between the two dividing knives 211, so that when the winding is completed and the paper roll is separated from the winding roller 2, the adhesive tape 42 can follow the bubble film to separate from the winding roller 2.

[0054] See also Figure 4 The winding roller 2 is provided with a control member. When the driving column 6 slides outward from the driving groove 23 , the control member controls the cutting knife 24 to cut the tape 42 between the two dividing knives 211 .

[0055] join Figure 4The cutting blade 24 is fixedly connected to a connecting column 243 on one side close to the central axis of the winding roller 2, and the connecting column 243 slides in the connecting groove 242. A control hole 232 connected to the connecting groove 242 is opened on the side wall of the driving groove 23, and the control hole 232 extends along the length direction of the winding roller 2, and the connecting column 243 protrudes into the control hole 232. Two fixed blocks are fixed to the outer peripheral side of the driving column 6, and each group of fixed blocks has two and are symmetrically arranged, and a hinge shaft is rotatably connected between the two fixed blocks in the same group.

[0056] See also Figure 4 and Figure 5 , the control member is a control plate 61, and two control plates 61 are symmetrically arranged and correspond to the connecting column 243 one by one. The two control plates 61 rotate on the two hinge shafts respectively, so that the control plates 61 can be turned over along the length direction of the winding roller 2. A torsion spring 612 is sleeved on the outer peripheral side of the hinge shaft, one end of the torsion spring 612 abuts against the side wall of the control plate 61 facing the notch of the driving groove 23, and the other end abuts against the outer peripheral side of the driving column 6. When in use, the torsion spring 612 is elastically released to push the control plate 61 to turn away from the notch of the driving groove 23. A limit block 611 corresponding to the control plate 61 is fixedly connected to the outer peripheral side of the driving column 6. The limit block 611 is located on the side of the control plate 61 facing away from the notch of the driving groove 23. When the torsion spring 612 pushes the control plate 61 to turn to be perpendicular to the driving column 6, the control plate 61 abuts against the limit block 611. At this time, the limit block 611 limits the control plate 61 from turning over in the direction away from the notch of the driving groove 23.

[0057] See also Figure 6 and Figure 7 The side of the connecting column 243 away from the tape 42 is inclined with a control surface 2431. When the driving column 6 slides outward from the driving groove 23, the control board 61 slides on the control surface 2431. At this time, the control board 61 pushes the connecting column 243 to move in the direction of the tape 42 until the connecting column 243 abuts against the control board 61 on the side facing away from the cutting knife 24, and the cutting knife 24 cuts off the tape 42 between the two cutting knives 211. When the driving column 6 slides into the driving groove 23, the control board 61 abuts against the connecting column 243 on the side facing away from the notch of the driving groove 23. At this time, the control board 61 flips toward the notch of the driving groove 23 until the control board 61 is separated from the connecting column 243. The torsion spring 612 (the torsion spring 612 is in the Figure 4 The control panel 61 is pushed to flip over until it contacts the limit block 611 .

[0058] See also Figure 4A limiting block is fixedly connected to the outer peripheral side of the connecting column 243, and a limiting groove is formed on the peripheral groove wall of the connecting groove 242, and the limiting block slides in the limiting groove. The winding roller 2 is provided with a pushing spring 241 located in the limiting groove, one end of the pushing spring 241 abuts against the limiting block, and the other end abuts against the groove wall of the limiting groove. When the connecting column 243 is separated from the control board 61, the pushing spring 241 is elastically released, pushing the connecting column 243 to slide toward the driving column 6, so that the cutting knife 24 is away from the tape 42.

[0059] See also Figure 2 In order to facilitate the cutting knife 24 to continue to drive the tape 42 between the two dividing knives 211 to move toward the storage roller 51 after cutting the tape 42, the winding roller 2 is provided with a pushing member. When the driving column 6 slides toward the outside of the driving groove 23, the pushing member pushes the dividing knife 211 away from the tape 42.

When in use, the adjustment spring 622 is elastically released to push the push column 62 to protrude out of the adjustment groove 621.

[0061] See also Figure 2 A pushing groove 233 is provided on the outer peripheral side of the driving groove 23 , the guide groove 2112 is connected to the pushing groove 233 , and the pushing column 62 slides in the pushing groove 233 .

[0062] See also Figure 7 A linkage column 2114 is fixedly connected to the middle position of the linkage bar 2113 on the side facing away from the dividing knife 211, and a pushing block 2115 is fixedly connected to the outer peripheral side of the linkage column 2114. The pushing block 2115 is inclined and has a pushing surface 2116 on the side away from the notch of the driving groove 23.

[0063] See also Figure 7 and Figure 8 The slider 623 is fixedly connected to the outer peripheral side of the push column 62 and away from the drive column 6. When the drive column 6 moves toward the notch of the drive groove 23, the slider 623 slides on the push surface 2116. At this time, the slider 623 drives the linkage column 2114 to move away from the tape 42 through the push block 2115. When the slider 623 and the push block 2115 are separated, the drive spring 2111 pushes the segmentation knife 211 to move toward the tape 42. The slider 623 faces away from the drive groove 23 (the drive groove 23 is in the Figure 6A control surface 2431 is obliquely opened on one side of the slot (marked in the middle). When the driving column 6 slides into the driving slot 23, the pushing block 2115 slides on the control surface 2431 to push the pushing column 62 into the adjusting slot 621 until the slider 623 moves away from the pushing block 2115, and the adjusting spring 622 pushes the pushing column 62 to slide out of the adjusting slot 621.

[0064] See also Fig. 9 The winding roller 2 is provided with a power assembly 8. When the driving column 6 slides outwards from the driving groove 23 and the segmentation knife 211 (the segmentation knife 211 is in Figure 7 When the dividing knife 211 is away from the adhesive tape 42 , the power assembly 8 drives the receiving roller 51 to rotate, so that the receiving roller 51 can drive the adhesive tape 42 to move toward the mounting groove 3 when the dividing knife 211 is away from the adhesive tape 42 .

[0065] See also Figure 7 and Fig. 9 The power assembly 8 includes a power rope 81 and a power block 82. The side walls on opposite sides of the storage groove 5 are connected to each other and are provided with rotation grooves 25, and the two ends of the storage roller 51 are respectively connected to the rotation grooves 25. The winding roller 2 is connected to a power groove, and the power block 82 is connected to the power groove. The power block 82 is a round block structure and is coaxially arranged with the storage roller 51. The end of the power block 82 facing the storage roller 51 is provided with a plug-in groove 821, and the end of the storage roller 51 extends and inserts into the plug-in groove 821, and the diameter of the storage roller 51 is smaller than the diameter of the plug-in groove 821. The power rope 81 is slidably arranged in the winding roller 2, and one end of the power rope 81 is fixed to the outer peripheral side of the power block 82, and the other end is fixed to the outer peripheral side of the driving column 6. In the initial state, the power rope 81 is wrapped around the outer peripheral side of the power block 82 and the power rope 81 is in a relaxed state. When the driving column 6 moves toward the driving groove 23 (the driving groove 23 is in Figure 6 When the dividing knife 211 slides outward from the adhesive tape 42, the driving column 6 drives the power rope 81 to slide into the driving groove 23 and gradually enters a tightened state until the dividing knife 211 moves away from the adhesive tape 42. At this time, the power rope 81 enters a tightened state. When the driving column 6 continues to slide outward from the driving groove 23, the power rope 81 drives the power block 82 to rotate.

[0066] See also Fig. 9 and Fig.10The outer peripheral side of the storage roller 51 is fixedly connected with a sliding tooth 511, and the sliding tooth 511 is slidably connected in the plug-in slot 821. The peripheral groove wall of the plug-in slot 821 is fixedly connected with a limiting tooth 822, and there are multiple limiting teeth 822 and they are evenly arranged along the circumference. The limiting teeth 822 and the sliding teeth 511 are made of elastic material, so that the limiting teeth 822 and the sliding teeth 511 can produce a certain elastic deformation. When the power rope 81 drives the power block 82 to rotate, the limiting teeth 822 unidirectionally support the sliding teeth 511. At this time, the storage roller 51 rotates with the power block 82, so that the tape 42 begins to wrap around the outer peripheral side of the storage roller 51.

[0067] See also Fig. 9 and Fig.10 The winding roller 2 is provided with a coil spring 823, which is located in the power groove. One end of the coil spring 823 is fixed to the side of the power block 82 away from the receiving roller 51, and the other end is fixed to the wall of the power groove. When the power rope 81 drives the power block 82 to rotate, the coil spring 823 enters a contracted state. When the driving column 6 slides into the driving groove 23, the power rope 81 enters a relaxed state. At this time, the coil spring 823 is elastically released, driving the power block 82 to reverse. The winding roller 2 is provided with a limiting member, which is a rubber layer 512. The rubber layer 512 is fixed to the groove wall of the rotating groove 25. The rubber layer 512 is in sliding contact with the receiving roller 51 to increase the resistance of the receiving roller 51 when rotating. When the coil spring 823 drives the power block 82 to rotate, the sliding tooth 511 slides on the sliding tooth 511 in one direction. At this time, the receiving roller 51 stops rotating under the restriction of the rubber layer 512, so that the power rope 81 is wound around the outer peripheral side of the power block 82.

[0068] The implementation principle of a bubble film production device in the embodiment of the present application is as follows:

[0069] When in use, first sleeve the paper tube on the outer circumference of the winding roller 2 so that the installation groove 3 is located between two adjacent paper tubes. Then slide the driving column 6 into the driving groove 23, and the support plate 31 drives the adhesive tape 42 to move until the adhesive surface is flush with the outer circumference of the paper tube. Then the machine body 1 can be opened to produce the bubble film. During production, the bubble film produced by the machine body 1 contacts the adhesive surface of the adhesive tape 42, so that the bubble film rotates with the winding roller 2 and is wound around the outer circumference of the paper tube.

[0070] When the production is completed and the wound paper tube and bubble film need to be removed, the driving column 6 is first slid toward the outside of the driving slot 23. At this time, the cutting knife 24 cuts the tape 42 and moves away from the tape 42. Then the power rope 81 drives the storage roller 51 to rotate, and the splitting knife 211 starts to move away from the tape 42. When the splitting knife 211 moves away from the tape 42, the power rope 81 drives the storage roller 51 to rotate and move the tape 42 toward the installation slot 3 until a section of the unsplit tape 42 moves away from the splitting knife 211. The driving spring 2111 drives the splitting knife 211 to move toward the tape 42, so that the splitting knife 211 starts to split the tape 42. Then, when the driving column 6 continues to move toward the outside of the driving column 6, the storage roller 51 continues to rotate until the tape 42 is driven to enter the connecting hole 22, and the tape 42 split between the two splitting knives 211 stops after passing through the cutting knife 24 on one side of the connecting hole 22. After that, remove the paper tube and the paper tube, finally install a new paper tube, and then slide the driving column 6 into the driving groove 23. The whole process is simple, and there is no need to wrap multiple sections of tape 42, which is conducive to improving the winding speed of the bubble film.

[0071] On the other hand, the present application discloses a method for producing a bubble film production device, comprising the following steps:

[0072] First, the paper tubes are respectively sleeved on the outer peripheral side of the winding roller 2 so that two adjacent paper tubes are located on both sides of the mounting groove 3; then, the driving column 6 is slid into the driving groove 23 so that the support plate 31 drives the tape 42 to the outside of the mounting groove 3 and is flush with the outer peripheral side of the paper tube; then, the machine body 1 is started to generate the bubble film, and the produced bubble film is wound on the winding roller 2; finally, when the winding is completed, the driving column 6 is slid out of the driving groove 23 so that the cutting knife 24 cuts the tape 42, and then the tape 42 that is not bonded with the bubble film is driven into the mounting groove 3 through the storage roller 51, and then the paper tube and the wrapped bubble film can be removed.

[0073] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
