Description

Technical Field

[0001] The present application relates to the field of bubble film machines, and in particular to a winding device of a bubble film machine. Background Art

[0002] Bubble film, also known as air cushion film, bubble film, bubble paper, etc., is a chemical product used for packaging filling to prevent pressure, moisture and shock. Because the middle layer of the air cushion film is filled with air, it is light, elastic, and has the properties of sound insulation, shock resistance and wear resistance. The bubble film machine is the equipment used to produce bubble film. After the bubble film is produced, it needs to be rolled up using a winding device and wait for storage;

[0003] In response to the above-mentioned related technologies, the inventor believes that the common bubble film machine winding device has the defect that a large amount of bubble film is wrapped around the winding roller and is difficult to remove. After the bubble film is produced, it will be wound around the winding roller in sequence. Although the surface of the winding roller is smooth, under the squeezing of layers of bubble film, the inner layer of bubble film will still be difficult to separate from the winding roller. Therefore, a winding device for a bubble film machine is proposed to solve the above problem.

[0004] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application. Therefore, it may contain information that does not constitute the prior art known to ordinary technicians in this field. Utility Model Content

[0007] A winding device for a bubble film machine includes an extrusion frame and a winder, the extrusion frame is installed on one side of the winder, two rotating shafts are installed on the side wall of the winder, and a plurality of clamping blocks are respectively installed on the side walls of the two rotating shafts, a sleeve is provided on the outer shell of the rotating shaft, and a plurality of clamping grooves are provided on the inner wall of the sleeve, and a plurality of the clamping blocks are respectively clamped in the plurality of clamping grooves, a working chamber is provided in the rotating shaft, and a limiting mechanism is installed in the working chamber.

[0008] Preferably, a groove is formed on the bottom wall of each of the card slots, and the length of the card slot is consistent with the length of the card block.

[0009] Preferably, the limiting mechanism includes a moving rod, a plurality of sliders and a plurality of protruding rods, the moving rod is arranged in the working chamber, the plurality of sliders are respectively against the side walls of the moving rod, the plurality of protruding rods are respectively arranged on the top walls of the plurality of sliders, the side walls of the block are provided with a plurality of extension holes, the plurality of protruding rods are respectively extended from the plurality of extension holes, the positions of the plurality of protruding rods correspond one-to-one to the positions of the plurality of grooves, the side walls of the moving rod are provided with a plurality of limiting grooves, and the size of the limiting grooves is consistent with the size of the slider.

[0010] Preferably, one end of the movement rod extends out of the sleeve and is provided with a pressing block, the other end of the movement rod is provided with a telescopic spring, and the other end of the telescopic spring is fixedly connected to the side wall of the working chamber.

[0011] Preferably, the depth of the limiting groove is greater than the distance the protruding rod extends from the extension hole.

[0012] In summary, this application has the following beneficial technical effects:

[0013] After being squeezed by the extrusion frame, the bubble film will be relatively smoothly wound onto the rotating shaft of the side wall of the winder. Since a sleeve is provided on the outside of the rotating shaft, the bubble film will be sleeved on the outer wall of the sleeve, and due to the restriction of the card block and the card slot, the sleeve can rotate with the rotating shaft, so that the bubble film is smoothly wound. When the bubble film is wrapped, the button can be pressed to make the moving rod move inward, and then the slider falls into the limiting groove. The protruding rod will retract from the extension hole because the position of the slider drops, thereby no longer restricting the position of the sleeve. At this time, the staff can easily remove the sleeve; compared with the existing technology, it is more convenient for the staff to remove the multiple layers of bubble film.

[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The embodiment of the present application discloses a rewinding device for a bubble film machine. Figure 1 A rewinding device for an air bubble film machine includes an extrusion frame 1 and a rewinder 2. The extrusion frame 1 is mounted on one side of the rewinder 2. The model of the rewinder 2 may be RFD-1500S.

[0020] Two rotating shafts 3 are installed on the side wall of the winding machine 2, and a number of clamping blocks 4 are installed on the side walls of the two rotating shafts 3 respectively. A sleeve 5 is provided on the outer shell of the rotating shaft 3, and a number of clamping slots 6 are opened on the inner wall of the sleeve 5. A groove 7 is opened on the bottom wall of each clamping slot 6. The length of the clamping slot 6 is consistent with the length of the clamping block 4. Several clamping blocks 4 are respectively clamped in several clamping slots 6. The cooperation between the clamping block 4 and the clamping slot 6 enables the rotating shaft 3 to drive the sleeve 5 to rotate together, thereby facilitating the winding of the bubble film.

[0021] Reference Figure 3 A working chamber is provided in the rotating shaft 3, and a limiting mechanism is installed in the working chamber. The limiting mechanism includes a moving rod 8, a plurality of sliders 9 and a plurality of protruding rods 10. The moving rod 8 is installed in the working chamber, and a plurality of sliders 9 are respectively against the side walls of the moving rod 8, and a plurality of protruding rods 10 are respectively installed on the top walls of the plurality of sliders 9. A plurality of extension holes 11 are provided on the side wall of the card block 4, and a plurality of protruding rods 10 are respectively extended from the plurality of extension holes 11. The positions of the plurality of protruding rods 10 correspond one-to-one to the positions of the plurality of grooves 7. A plurality of limiting grooves 12 are provided on the side wall of the moving rod 8. The size of the limiting groove 12 is consistent with the size of the slider 9. The depth of the limiting groove 12 is greater than the distance that the protruding rod 10 extends from the extension hole 11. The slider 9 can be completely received in the limiting groove 12. When the slider 9 enters the limiting groove 12, the protruding rod 10 can be retracted into the extension hole 11, and the position of the sleeve 5 is no longer restricted.

[0022] One end of the moving rod 8 extends out of the sleeve 5 and is equipped with a push block 13. The other end of the moving rod 8 is equipped with a telescopic spring 14. The other end of the telescopic spring 14 is fixedly connected to the side wall of the working chamber. In the initial state of the telescopic spring 14, the moving rod 8 will be pushed outward, thereby ensuring that the slider 9 will not enter the limiting groove 12.

[0023] The implementation principle of the winding device of a bubble film machine in the embodiment of the present application is as follows: after being squeezed by the extrusion frame 1, the bubble film will be relatively smoothly wound onto the rotating shaft 3 on the side wall of the winder 2. Since a sleeve 5 is provided on the outside of the rotating shaft 3, the bubble film will be sleeved on the outer wall of the sleeve 5, and due to the restriction of the clamping block 4 and the clamping groove 6, the sleeve 5 can rotate with the rotating shaft 3, so that the bubble film is smoothly wound. When the bubble film is wound, the button 13 can be pressed to make the moving rod 8 move inward, thereby making the slider 9 fall into the limiting groove 12. The protruding rod 10 will retract from the extension hole 11 because the position of the slider 9 drops, thereby no longer restricting the position of the sleeve 5. At this time, the staff can easily remove the sleeve 5.
