[0032] The following will be combined with the drawings in the specification of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0033] Reference Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6The utility model provides an embodiment of a winding film reel, comprising a first baffle 1 and a second baffle 20, a winding assembly for winding the winding film is arranged between the first baffle 1 and the second baffle 20, an outer sleeve 2 and an inner sleeve 3 are arranged on the adjacent sides of the first baffle 1 and the second baffle 20, the outer wall of the inner sleeve 3 is slidably connected to the inside of the outer sleeve 2, and the outer sleeve 2 is fixedly connected to the first baffle 1, the inner sleeve 3 is fixedly connected to the second baffle 20, a pull rod 4 is slidably connected to the middle part of the second baffle 20, one end of the pull rod 4 is located at one side of the interior of the inner sleeve 3, and a pressure plate 125 is slidably connected to the other side of the interior of the inner sleeve 3, a spring 6 is arranged between the pressure plate 125 and the second baffle 20, the pull rod 4 is fixedly connected to the pressure plate 125, one end of the pull rod 4 is rotatably connected to a push rod 9, one end of the push rod 9 is rotatably connected to a folding rod 7, one side of the folding rod 7 is fixedly connected to an insertion rod 8, the end of the insertion rod 8 is located inside the outer sleeve 2, and the folding rod 7 is rotatably connected to the inner sleeve 3.
[0034] When in use, by pulling the pull rod 4 to move it closer to and away from the first baffle 1, the pull rod 4 can pull the push rod 9 to rotate the folding rod 7 toward the inside of the inner sleeve 3, and then the insertion rod 8 can be pulled out from the inside of the outer sleeve 2. At this time, the first baffle 1 and the second baffle 20 can be pulled to drive the inner sleeve 3 and the outer sleeve 2 to slide against each other, thereby achieving the purpose of adjusting the distance between the first baffle 1 and the second baffle 20, and the pull rod 4 will also drive the pressure plate 125 to move closer to the second baffle 20. At this time, the spring 6 can be compressed. Therefore, when the distance adjustment between the first baffle 1 and the second baffle 20 is completed, release the pull rod 4. At this time, the spring 6 will extend the pressure plate 125 to drive the folding rod 7 to reverse. At this time, the insertion rod 8 can be re-extended to the inside of the outer sleeve 2 to lock the distance between the first baffle 1 and the second baffle 20, so that wrapping films of different widths can be wound.
[0035] Reference Figure 2 , Figure 3 and Figure 5 The inner sleeve 3 is provided with a through hole on one side close to the first baffle 1, and the middle part of the insertion rod 8 is located inside the through hole. The inner wall of the outer sleeve 2 is provided with multiple openings on one side close to the first baffle 1, and the end of the insertion rod 8 is located inside one opening. The folding rod 7 is arranged in a V shape, and the folding part of the folding rod 7 is rotatably connected to the mounting seat 18, and the mounting seat 18 is fixedly connected to the inner sleeve 3.
[0036] The through hole can provide space for the swing of the insertion rod 8, and a plurality of openings are provided on the inner wall of the outer sleeve 2. By inserting the insertion rod 8 into different openings, multi-level adjustment of the distance between the first baffle 1 and the second baffle 20 can be achieved.
[0037] Reference Figure 3 , Figure 4 and Figure 5The outer wall of the inner sleeve 3 is fixedly connected with a clamping strip 10, and the inner wall of the outer sleeve 2 is provided with a clamping groove 11. The clamping strip 10 is slidably connected inside the clamping groove 11, and the cross-sections of the clamping strip 10 and the clamping groove 11 are both set to be T-shaped. The other end of the pull rod 4 is fixedly connected with a lever 19, and the middle part of the far side of the first baffle 1 and the second baffle 20 is fixedly connected with a handle 17.
[0038] When the distance between the first baffle 1 and the second baffle 20 is adjusted, the inner sleeve 3 and the outer sleeve 2 will slide relative to each other, and the clamping strip 10 can be driven to slide inside the clamping groove 11. Therefore, by sliding relative to each other between the clamping strip 10 and the clamping groove 11, the outer sleeve 2 and the inner sleeve 3 can slide relative to each other while avoiding rotation between the two. Therefore, the phenomenon that the insertion rod 8 cannot be inserted into the inner opening of the outer sleeve 2 can be avoided.
[0039] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The winding assembly includes a limit strip 16 and a winding strip 15, the winding strip 15 is fixedly connected to the first baffle 1, the limit strip 16 is fixedly connected to the second baffle 20, and a plurality of limit strips 16 and winding strips 15 are provided, and the plurality of winding strips 15 and the plurality of limit strips 16 are equidistantly distributed in a circle along the central axis of the first baffle 1, and the plurality of winding strips 15 and the plurality of limit strips 16 are staggered with each other. Both sides of the outer wall of the winding strip 15 are provided with protrusions, and both sides of the outer wall of the limit strip 16 are provided with openings, and the protrusions are engaged in the inside of the openings.
[0040] The wrapping film can be rolled up by the rolling strip 15 and the limiting strip 16, and when the distance between the first baffle 1 and the second baffle 20 is adjusted, the limiting strip 16 and the rolling strip 15 will slide against each other. Therefore, the mutual engagement of the protrusion and the opening can prevent the first baffle 1 and the second baffle 20 from detaching from each other, and can also prevent the first baffle 1 and the second baffle 20 from sliding against each other.
[0041] Reference Figure 1 , Figure 2 and Figure 4 A cover plate is arranged between the first baffle plate 1 and the second baffle plate 20, and grooves 14 are provided on the tops of the first baffle plate 1 and the second baffle plate 20, and the two sides of the cover plate are respectively in the grooves 14 on the two sides, and knobs 13 are threadedly connected on both sides of the middle part of the cover plate, and the bottoms of the knobs 13 on both sides are threadedly connected to the tops of the first baffle plate 1 and the second baffle plate 20, respectively.
[0042] After winding is completed, the pressure plate 125 is clamped in the clamping groove 11 on the first baffle plate 1 and the second baffle plate 20, and finally the knob 13 is installed to fix it, so that the winding film can be compressed after winding is completed, thereby preventing the winding film from becoming loose.
[0043] Working principle: When in use, first remove the knob 13 and disengage the pressure plate 125 from the first baffle 1 and the second baffle 20. At this time, the wrapping film can be rolled up on the outside of the winding strip 15 and the limiting strip 16. When it is necessary to adjust the distance between the first baffle 1 and the second baffle 20, first pull the lever 19 to drive the pull rod 4 to move and move it away from the first baffle 1. At this time, the pressure plate 125 can be used to compress the spring 6, and the pull rod 4 can be used to pull the top rod 9 and drive the folding rod 7 to rotate toward the inside of the inner sleeve 3. At this time, the insertion rod 8 can be retracted to move it out of the inside of the outer sleeve 2, and then the handle 17 can be pulled to close the first baffle 1. The distance between a baffle 1 and a second baffle 20 is adjusted, and at this time, the inner sleeve 3 and the outer sleeve 2 can slide relative to each other, and the limit strip 16 and the winding strip 15 can slide relative to each other. When the distance between the first baffle 1 and the second baffle 20 is adjusted, the pull rod 4 is released. At this time, the spring 6 extends the pressure plate 125 to drive the pull rod 4 to approach the second baffle 20, and then drives the folding rod 7 to reverse and push the insertion rod 8 out and insert it into the opening inside the outer sleeve 2. At this time, the distance between the first baffle 1 and the second baffle 20 can be locked, so that the device can be used to wind wrapping films of different widths.
