[0037] like Figures 1 to 10 As shown in the figure, in one embodiment, a door frame packaging and winding mechanism 1 includes a frame 10 and a winding assembly 20, wherein the winding assembly 20 includes a driving member 21, a crown gear 22, a column gear 23, a movable gear 24, a sliding gear 25, a middle gear 26, a rotating shaft 29, an adjusting member 27 and two winding members 28, wherein the driving member 21 is arranged on the frame 10, and the crown gear 22 is arranged on the output shaft of the driving member 21, and the middle gear 26 and the movable gear 24 are both rotatably arranged on two opposite sides of the frame 10, and the middle gear 26 and the movable gear 24 are both engaged with the crown gear 22, and the column gear 23 is coaxially arranged on the crown gear 22, and the column gear 23 is located between the middle gear 26 and the movable gear 24, The rotating shaft 29 is rotatably set on the frame 10, and the sliding gear 25 is slidably set on the rotating shaft 29. The two winding members 28 are respectively set on the rotating shaft 29 and the movable gear 24. The two winding members 28 are used to wrap the door frame. The adjusting member 27 is set on the frame 10, and the adjusting member 27 is engaged with the sliding gear 25. When the adjusting member 27 drives the sliding gear 25 to engage with the middle gear 26, the rotating shaft 29 and the movable gear 24 respectively drive the two winding members 28 to rotate in the same direction. When the adjusting member 27 drives the sliding gear 25 to engage with the column gear 23, the rotating shaft 29 and the movable gear 24 respectively drive the two winding members 28 to rotate in two opposite directions.

[0038] It should be noted that the driving member 21 is a motor structure, with the crown gear 22 coaxially mounted on the output shaft of the driving member 21, and the column gear 23 coaxially mounted on the crown gear 22, so that the driving member 21 can drive the crown gear 22 and the column gear 23 to rotate simultaneously. Furthermore, the teeth on the crown gear 22 are located on the side of the crown gear 22 facing away from the driving member 21, while the teeth on the column gear 23 are located on the side of the column gear 23 facing away from the crown gear 22. The diameter of the crown gear 22 is larger than the diameter of the column gear 23, and the thickness of the crown gear 22 is smaller than the thickness of the column gear 23, so that there is a gap and thickness difference between the teeth of the crown gear 22 and the teeth of the column gear 23. Furthermore, the movable gear 24 is rotatably mounted on the frame 10, the rotating shaft 29 is rotatably mounted on the frame 10, and the sliding gear 25 is slidably mounted on the rotating shaft 29. The sliding gear 25 and movable gear 24 are respectively located on opposite sides of the frame 10, and the sliding gear 25 and movable gear 24 are respectively located on the side facing the teeth of the crown gear 22. The middle gear 26 is rotatably mounted on the frame 10, and the middle gear 26 and the sliding gear 25 are respectively located on the same side of the frame 10. Furthermore, the crown gear 22 is centered on the axis, and its ends respectively mesh with the middle gear 26 and movable gear 24. When the driving member 21 drives the crown gear 22 to rotate, the crown gear 22 can simultaneously drive the middle gear 26 and movable gear 24 to rotate in opposite directions. Furthermore, the diameter of the movable gear 24 is larger than the diameters of the sliding gear 25 and the middle gear 26. It should be noted that the centers of the movable gear 24 and the sliding gear 25 are both located on the same axis, and the middle gear 26 is located between the sliding gear 25 and the crown gear 22. When the middle gear 26 engages with the sliding gear 25 and the crown gear 22, respectively, the distance from the axis of the sliding gear 25 to the outer diameter of the middle gear 26 end away from the sliding gear 25 is consistent with the radius of the movable gear 24. This allows both ends of the crown gear 22 to engage with the middle gear 26 and the movable gear 24 simultaneously, thereby allowing the sliding gear 25 and the movable gear 24 to rotate simultaneously in the same direction when the crown gear 22 rotates. Furthermore, an adjustment member 27 is provided on the frame 10, and the adjustment member 27 is located below the sliding gear 25 and is engaged with the sliding gear 25. Furthermore, the centers of the sliding gear 25 and the movable gear 24 are both located on the same axis. The sliding gear 25 is slidably mounted on the frame 10 along the axis, so that the adjustment member 27 can drive the sliding gear 25 to slide toward or away from the movable gear 24.Furthermore, the column gear 23 is arranged on the crown gear 22, and the end of the column gear 23 with teeth is located between the middle gear 26 and the moving gear 24, and the teeth of the column gear 23 and the teeth of the middle gear 26 away from the crown gear 22 are all on the same horizontal line, so that the sliding gear 25 can engage with the middle gear 26 and also with the column gear 23. When the adjusting member 27 drives the sliding gear 25 to engage with the middle gear 26, the driving member 21 drives the crown gear 22 to rotate, and the crown gear 22 drives the middle gear 26 and the moving gear 24 to rotate in two opposite directions respectively, and the middle gear 26 drives the sliding gear 25 to rotate in the same direction as the moving gear 24. Furthermore, since the crown gear 22 and the column gear 23 are fixed together, when the driving member 21 rotates, the crown gear 22 and the column gear 23 will rotate together in the same direction. When the adjusting member 27 drives the sliding gear 25 to slide toward the movable gear 24 so that the sliding gear 25 engages with the column gear 23, when the driving member 21 drives the column gear 23 and the crown gear 22 to rotate at the same time, the column gear 23 drives the sliding gear 25 to rotate, and at the same time, the crown gear 22 drives the movable gear 24 to rotate. The sliding gear 25 and the movable gear 24 are both located on both sides of the axial direction of the crown gear 22 / column gear 23, so that the crown gear 22 / column gear 23 respectively drive the sliding gear 25 and the movable gear 24 to rotate in two opposite directions.

[0039] It should be noted that a convex strip is provided on the rotating shaft 29, and a slot is provided on the sliding gear 25. The sliding gear 25 is sleeved on the rotating shaft 29, so that the sliding gear 25 can slide along the axial direction of the rotating shaft 29 and can drive the rotating shaft 29 to rotate relative to the frame 10. Furthermore, a rotating column 241 is provided on the movable gear 24, and the rotating column 241 is rotatably connected to the frame 10. One of the winding members 28 is provided on the end of the rotating shaft 29 away from the sliding gear 25, and the other winding member 28 is provided on the end of the rotating column 241 away from the movable gear 24. When the adjusting member 27 drives the sliding gear 25 to engage with the middle gear 26, the rotating shaft 29 and the rotating column 241 respectively drive the two winding members 28 to rotate in the same direction. When the adjusting member 27 drives the sliding gear 25 and makes the sliding gear 25 engage with the column gear 23, the rotating shaft 29 and the rotating column 241 respectively drive the two winding members 28 to rotate in two opposite directions. In this way, the two winding members 28 respectively drive the two packaging materials to wrap and package the door frame in the same direction or in two opposite directions.

[0040] like Figures 1 to 2 、 Figures 4 to 6As shown, in one embodiment, the adjusting member 27 includes a rocker arm 271, a block 272 and a cylinder 273. The cylinder 273 is arranged on the frame 10. One end of the rocker arm 271 is rotatably fixed on the frame 10. The other end of the rocker arm 271 is rotatably connected to the output shaft of the cylinder 273. One end of the block 272 is rotatably connected to the rocker arm 271, and the other end of the block 272 is engaged with the sliding gear 25.

[0041] It should be noted that the cylinder 273 is mounted on the frame 10 and is located on one side of the movable gear 24. One end of the rocker arm 271 is rotatably connected to the output end of the cylinder 273, while the other end of the rocker arm 271 passes through the bottom of the sliding gear 25 and is rotatably connected to the frame 10, and is located on one side of the sliding gear 25. Furthermore, the clamping block 272 has a U-shaped structure, with the bottom of the clamping block 272 rotatably connected to the middle position of the rocker arm 271, and U-shaped grooves are provided on both sides of the clamping block 272. It should be noted that circular clamping platforms are provided on both sides of the sliding gear 25 in the axial direction. The diameter of the clamping platforms is consistent with the diameter of the U-shaped groove, so that the two sides of the clamping block 272 can be clamped with the clamping platforms on both sides of the sliding gear 25, and the sliding gear 25 can rotate relative to the clamping block 272. Thus, when the cylinder 273 pushes one end of the rocker arm 271, the block 272 on the rocker arm 271 drives the sliding gear 25 to slide away from the column gear 23 to disengage, and the sliding gear 25 slides closer to the middle gear 26 to engage with each other. When the cylinder 273 pulls one end of the rocker arm 271, the block 272 on the rocker arm 271 drives the sliding gear 25 to slide away from the middle gear 26 to disengage, and the sliding gear 25 slides closer to the column gear 23 to engage with each other. Furthermore, when the sliding gear 25 engages with the middle gear 26, the two winding members 28 rotate in the same direction. When the sliding gear 25 engages with the column gear 23, the two winding members 28 rotate in opposite directions. It should be noted that the thickness of the sliding gear 25 is less than the diameter difference between the crown gear 22 and the column gear 23. Since the middle gear 26 and the column gear 23 can drive the sliding gear 25 to rotate in different directions, when the adjusting member 27 drives the sliding gear 25 to switch back and forth between the middle gear 26 and the column gear 23, the sliding gear 25 can be located between the middle gear 26 and the column gear 23, avoiding the two ends of the sliding gear 25 from being simultaneously engaged with the middle gear 26 and the column gear 23, resulting in a stuck phenomenon. For example, when one end of the sliding gear 25 is engaged with the middle gear 26, the other end of the sliding gear 25 is not disengaged from the column gear 23, or when one end of the sliding gear 25 is engaged with the column gear 23, the other end of the sliding gear 25 is not disengaged from the middle gear 26. In this way, the two winding members 28 can adjust the winding direction according to the actual packaging process to meet the diversified production needs.

[0042] like Figures 1 to 7As shown, in one embodiment, a rotating column 241 is provided on the movable gear 24 , and the rotating column 241 is rotatably provided on the frame 10 , wherein one of the winding members 28 is sleeved on the rotating column 241 , and the other winding member 28 is sleeved on the rotating shaft 29 .

[0043] It should be noted that the rotating shaft 29 and the rotating column 241 are respectively rotatably arranged on two opposite side surfaces of the frame 10, and the rotating shaft 29 and the rotating column 241 are both located in the same axial direction. The middle position of the rotating shaft 29 and the rotating column 241 are both circular structures, and a clamping strip is provided on both ends. The two ends of the rotating shaft 29 are respectively engaged with the sliding gear 25 and one of the winding members 28, and the two ends of the rotating column 241 are respectively engaged with the moving gear 24 and the other winding member 28. Furthermore, the lengths of one end of the rotating shaft 29 and the rotating column 241 are not consistent, and the length of one end of the rotating shaft 29 is greater than the length of the rotating column 241. It should be noted that the end of the rotating shaft 29 away from the winding member 28 extends from the circular structure to the bottom of the column gear 23 and the middle gear 26, so that the sliding gear 25 can slide and engage with the middle gear 26 or the column gear 23 respectively.

[0044] like Figures 1 to 3 As shown, in one embodiment, the winding member 28 includes a driving wheel 281, a ring 282, a belt 283 and two guide wheels 284. The driving wheel 281 is mounted on the rotating shaft 29 / rotating column 241, the ring 282 is rotatably mounted on the frame 10, and the two guide wheels 284 are respectively rotatably mounted on the frame 10, and the two guide wheels 284 are respectively located on both sides of the ring 282. The belt 283 is respectively mounted on the driving wheel 281 and the two guide wheels 284 so that the belt 283 is in contact with the ring 282.

[0045] It should be noted that the driving wheel 281 is clamped onto the rotating shaft 29 so that the rotating shaft 29 drives the driving wheel 281 to rotate. Furthermore, the ring 282 is a circular structure with a notch formed therein, so that the ring 282 tends to be a C-shaped circular ring structure. The ring 282 is rotatably arranged on the outer surface of the frame 10. The outer circumferential surface of the ring 282 is provided with teeth, and the two guide wheels 284 are rotatably arranged on both sides of the ring 282. It should be noted that the belt 283 is provided with teeth on both sides. When the belt 283 is mounted on the driving wheel 281 and the two guide wheels 284, the teeth on the inner side of the belt 283 mesh with the driving wheel 281 and the two guide wheels 284 respectively, while the teeth on the outer side of the belt 283 mesh with the teeth on the outer wall of the ring 282. In this way, the driving wheel 281 can drive the ring 282 to rotate.

[0046] In one embodiment, the driving wheel 281 and the two guide wheels 284 are sprocket structures, the belt 283 is a chain structure, and a plurality of chain teeth are provided on the outer wall of the ring 282, so that the ring 282 can be driven to rotate by the chain.

[0047] like Figure 3 、 Figure 10 As shown, in one embodiment, a ring rail 13 is further provided on the frame 10 , and the ring rail 13 is engaged with the ring 282 so that the ring 282 rotates along the ring rail 13 .

[0048] It should be noted that semicircular gaps are provided on the two facing sides of the frame 10. The ring rail 13 is a circular structure with a gap provided thereon, so that the ring rail 13 tends to be a C-shaped circular ring structure. The ring rail 13 is provided on the frame 10 and is arranged along the circumference of the semicircular gap. The ring 282 is provided with a slide groove along the circumference. The slide groove is consistent with the diameter of the slide rail, so that the slide groove can be engaged with the ring rail 13, thereby allowing the ring 282 to slide along the slide rail. Since the ring rail 13 and the ring 282 are both circular ring structures, when the belt 283 drives the ring 282 to slide along the ring rail 13, the ring 282 rotates relative to the frame 10. Furthermore, a material placement column is provided on the ring 282. The material placement column is located at the end of the ring 282 away from the opening, and the material placement column is used to install packaging materials. When the door frame is inserted from the notch position of the ring 282 to the axis position of the ring 282, the belt 283 drives the ring 282 to rotate around the door frame, thereby driving the packaging material on the material placement column to rotate around the door frame, so that the packaging material is wrapped around the door frame.

[0049] It should be noted that the packaging materials are all coiled. When the ring 282 rotates clockwise with the door frame as the center, the packaging material unwinds in a counterclockwise direction so that the packaging material can be unwound and wrapped around the door frame. When the ring 282 rotates counterclockwise with the door frame as the center, the packaging material unwinds in a clockwise direction so that the packaging material can be unwound and wrapped around the door frame. Furthermore, when both rings 282 rotate clockwise, the packaging materials on both rings 282 unwind in a counterclockwise direction. When both rings 282 rotate counterclockwise, the packaging materials on both rings 282 unwind in a clockwise direction. When the two rings 282 rotate in opposite directions, the two packaging materials on the two rings 282 unwind in opposite directions. In this way, the door frame packaging and winding mechanism 1 of the present application can wrap the door frame with two packaging materials at the same time to improve the work efficiency of packaging production, and can realize winding of two packaging materials in the same direction or in opposite directions to meet diverse production needs.

[0050] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
