[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] First Embodiment

[0027] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of a PE film take-up and take-down machine that is easy to clamp, provided by this utility model; Figure 2 for Figure 1 The diagram shows the support frame structure. Figure 3 for Figure 1 The diagram shows a cross-sectional view of the cleaning frame. Figure 4 for Figure 1 The enlarged schematic diagram of part A is shown. A PE film take-up and take-down machine that is easy to clamp includes: a support frame 1, on both sides of the support frame 1 are provided with mounting grooves 11, and a plurality of ball bearings 12 are rolledly connected to the inner side of the mounting grooves 11;

[0028] The take-up and release roller 6 is disposed on the inner side of the mounting groove 11 and on the top of the plurality of balls 12. Both ends of the take-up and release roller 6 are provided with snap-fit ​​grooves 61.

[0029] A fixed base 5 is fixedly installed on the bottom of the inner side of the support frame 1. A drive telescopic component 51 is fixedly installed on both sides of the fixed base 5. A connecting frame 52 is fixedly installed on the moving end of the drive telescopic component 51. A rotating shaft 53 is provided on both sides of the support frame 1. A snap-fit ​​plate 54 is fixedly installed on the opposite end of the two rotating shafts 53. A drive motor 55 is fixedly installed on one side of one connecting frame 52. The output end of the drive motor 55 is rotatably connected to one of the rotating shafts 53. The other rotating shaft 53 is rotatably connected to the other connecting frame 52.

[0030] By setting multiple balls 12, it is convenient for the take-up and take-down rollers 6 to rotate on the inner side of the mounting groove 11 during use.

[0031] There are two connecting brackets 52 and two rotating shafts 53. One rotating shaft 53 is rotatably connected to the connecting bracket 52, and the other rotating shaft 53 is connected to the output end of the drive motor 55, thereby being installed on the other connecting bracket 52.

[0032] The snap-fit ​​plate 54 snaps into the inner side of the snap-fit ​​groove 61.

[0033] The inner side of the support frame 1 is rotatably connected to a first guide roller 2. A cleaning frame 3 is provided on one side of the first guide roller 2. Cleaning blades 31 are fixedly installed on both sides of the inner side of the cleaning frame 3. A second guide roller 4 is provided on one side of the cleaning frame 3.

[0034] The cleaning frame 3 is fixedly installed on the inner side of the support frame 1, and the second guide roller 4 is rotatably connected to the inner side of the support frame 1.

[0035] When feeding and unloading PE film, the PE film is placed on top of the first guide roller 2 and passed through the middle of the two cleaning blades 31. Then the PE film is placed at the bottom of the second guide roller 4 and then wrapped around the outer side of the take-up roller 6. In this way, when taking up and unloading the PE film, the cleaning blades 31 can slide on the surface of the PE film to clean the burrs on the surface of the PE film.

[0036] The working principle of the PE film take-up and take-down machine that is easy to clamp provided by this utility model is as follows:

[0037] During the feeding process, the take-up and release roller 6 is moved to the inner side of the mounting groove 11 and positioned on top of the ball bearing 12. Then, the take-up and release roller 6 is rotated to align the snap-fit ​​groove 61 and the snap-fit ​​plate 54. Next, the drive telescopic component 51 is activated, causing the drive telescopic component 51 to move the connecting frame 52 towards one end of the take-up and release roller 6, thereby snapping the snap-fit ​​plate 54 onto the inner side of the snap-fit ​​groove 61, which serves to clamp and limit the take-up and release roller 6. Then, the drive motor 55 is activated, causing the drive motor 55 to rotate the rotating shaft 53, which is then snapped onto the inner side of the snap-fit ​​groove 61 via the snap-fit ​​plate 54, driving the take-up and release roller 6 to rotate, thus performing the take-up and release operation of the PE film.

[0038] Compared with related technologies, the PE film take-up and take-down machine that is easy to clamp provided by this utility model has the following beneficial effects:

[0039] By placing the take-up and release roller 6 on the inner side of the mounting groove 11 and driving the telescopic component 51 to move the two connecting frames 52 toward both ends of the take-up and release roller 6, the snap-fit ​​plate 54 is snapped into the inner side of the snap-fit ​​groove 61, which serves to clamp and limit the take-up and release roller 6. In this way, the replacement of the take-up and release roller 6 is convenient and quick, without the need for manual locking by the staff, thus reducing the physical exertion of the staff.

[0040] Second Embodiment

[0041] Please refer to the following: Figure 5 and Figure 6 Based on the first embodiment of this application which provides a PE film take-up and take-down machine that is easy to clamp, the second embodiment of this application proposes another PE film take-up and take-down machine that is easy to clamp. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0042] Specifically, the second embodiment of this application provides a PE film take-up and take-down machine that is easy to clamp, wherein a top frame 7 is fixedly installed on the top of the support frame 1, and motors 71 are fixedly installed at both ends of the top of the top frame 7, and lead screws 72 are fixedly installed at the output end of the motors 71.

[0043] The outer side of the lead screw 72 is threadedly connected to a fixing block 73, and a feeding rod 74 is fixedly installed on one side of the fixing block 73.

[0044] An extension rod 75 is slidably connected to one end of the feeding rod 74.

[0045] Please see Figure 6 A limiting component is fixedly installed on one side of the feeding rod 74, and a limiting groove is opened at a corresponding position on the side of the support frame 1. When the feeding rod 74 moves up and down, the limiting component can slide on the inner side of the limiting groove, thereby limiting the feeding rod 74.

[0046] The working principle of the PE film take-up and take-down machine that is easy to clamp provided by this utility model is as follows:

[0047] When feeding is required, place the take-up roller 6 on top of the feeding rod 74, then start the two motors 71, so that the motors 71 drive the lead screw 72 to make a threaded connection inside the fixing block 73, and then the fixing block 73 drives the feeding rod 74 to move upward until the top of the feeding rod 74 moves to a position flush with the top of the mounting groove 11. Then, pull the extension rod 75 to one side of the mounting groove 11, and then move the take-up roller 6 to the inner side of the mounting groove 11.

[0048] During the subsequent unloading process, the extension rod 75 is first moved to the bottom of the take-up and release roller 6, and then the feeding rod 74 drives the extension rod 75 to move upward, so that the take-up and release roller 6 moves out from the inner side of the mounting groove 11. Then, the take-up and release roller 6 is pushed onto the top of the feeding rod 74, and the extension rod 75 is retracted into the inside of the feeding rod 74. Then, the feeding rod 74 is moved downward to unload the material.

[0049] Compared with related technologies, the PE film take-up and take-down machine that is easy to clamp provided by this utility model has the following beneficial effects:

[0050] The motor 71, lead screw 72, fixing block 73, feeding rod 74 and extension rod 75 work together to automatically move the take-up and release roller 6 to one side of the mounting groove 11 and remove the take-up and release roller 6 from the inner side of the mounting groove 11 during use. This eliminates the need for manual handling of the take-up and release roller 6 by the user, thereby reducing the physical exertion of the staff.

[0051] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
