Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1-7 , the present utility model provides a technical solution: a rewinding roller for the production of PE protective film, including a first frame body 1, a second frame body 2 and a power frame 3. Bearing frames 6 and first motors 7 are provided on one side of the first frame body 1 and the second frame body 2. The first frame body 1 includes a first substrate 11, and three groups of driven gears 12 are provided on the inner side surface of the first substrate 11. The power frame 3 includes a second motor 31, the output shaft of the second motor 31 is connected to a driving gear 32, and the driving gear 32 meshes with the driven gear 12 for transmission. The second frame body 2 includes a second substrate 21, and three groups of fixed seats 22 are provided on the inner side surface of the second substrate 21. A rewinding roller 5 is mounted between the driven gear 12 and the fixed seat 22.

[0027] Among them, when the second motor 31 works, it drives the driving gear 32 to rotate. The driving gear 32 drives the driven gear 12 to rotate synchronously. The driven gear 12 drives the rewinding roller 5 to rotate. The rotating rewinding roller 5 rewinds the PE protective film.

[0028] Among them, the first motor 7 on one side of the first frame 1 is used to drive the rotation of the first substrate 11, and the first motor 7 on one side of the second frame 2 is used to drive the rotation of the second substrate 21. When the first substrate 11 rotates, it drives the three groups of driven gears 12 inside it to move synchronously. When the second substrate 21 rotates, it drives the three groups of fixed seats 22 inside it to move synchronously. The first motors 7 on both sides work synchronously to drive the driven gears 12 and the fixed seats 22 to move synchronously. When the driven gears 12 and the fixed seats 22 move, they drive the rewinding roller 5 between them to move synchronously;

[0029] By controlling the number of rotation turns and the rotation direction of the first motor 7, the rotation angle and rotation direction of the first substrate 11 and the second substrate 21 are precisely controlled, so as to achieve precise control of the position of the rewinding roller 5;

[0030] When the rewinding of the PE protective film outside one group of rewinding rollers 5 is completed, the cutting mechanism cuts the PE protective film. The movement of the rewinding roller 5 is controlled by the first motor 7 to move the rewinding roller 5 after rewinding out of the working position, and at the same time move a new rewinding roller 5 to be rewound into the working position, realizing the quick change of the rewinding roller 5 and quickly putting it into use.

[0031] Among them, the first frame 1 and the second frame 2 form a roller frame structure. Multiple installation positions for the rewinding rollers 5 are provided on the overall roller frame structure, and multiple groups of rewinding rollers 5 can be pre-installed. The number of installation positions can be selected according to actual use requirements. By performing the quick change operation of the rewinding roller 5, the rewinding efficiency is improved, and the rewinding roller 5 after winding can be disassembled while the rewinding operation is in progress, shortening the downtime.

[0032] Among them, a plug-in shaft 51 is provided at one end of the rewinding roller 5, and a plug-in seat 121 is provided at one end of the driven gear 12. The plug-in shaft 51 of the rewinding roller 5 is plugged and fixed in the plug-in seat 121 of the driven gear 12, and a certain external force can be used to move the plug-in shaft 51 out of the inside of the plug-in seat 121, and the connection method is simple.

[0033] Among them, three bearing seats 13 are provided on the outer side surface of the first substrate 11. The three bearing seats 13 correspond to the three groups of driven gears 12 one by one, and the other end of the driven gear 12 is connected to the bearing seat 13 through a bearing. The driven gear 12 can rotate relative to the first substrate 11 under the meshing drive of the driving gear 32.

[0034] Among them, a bearing connection head 52 is provided at the other end of the rewinding roller 5, and the bearing connection head 52 is embedded in the fixed seat 22 and is fixedly connected to the fixed seat 22 through a tightening screw 221. The fixed seat 22 includes a fixed groove, and the bearing connection head 52 is located in the fixed groove.

[0035] When installing the rewinding roller 5, insert the insertion shaft 51 at one end of the rewinding roller 5 into and fix it in the insertion seat 121 of the driven gear 12, and move the bearing connection head 52 at the other end of the rewinding roller 5 into the fixing groove of the fixing seat 22. As Figure 5 shown, tighten the fastening screw 221 for fastening and fixing, and fix the bearing connection head 52 and the fixing seat 22 together;

[0036] When disassembling the rewinding roller 5, loosen the fastening screw 221, apply a certain external force to move the insertion shaft 51 out of the inside of the insertion seat 121, and then move the bearing connection head 52 out of the fixing groove of the fixing seat 22;

[0037] The roller body of the rewinding roller 5 is connected to the bearing connection head 52 through a bearing. The roller body of the rewinding roller 5 can rotate relative to the bearing connection head 52. When the driven gear 12 rotates driven by the meshing of the driving gear 32, it drives the rewinding roller 5 to rotate synchronously. The rotating rewinding roller 5 rewinds the PE protective film.

[0038] Among them, an adjusting component 4 is arranged at the lower end of the power frame 3. The position of the power frame 3 is adjusted through the adjusting component 4, that is, the position of the driving gear 32 is adjusted.

[0039] Among them, the adjusting component 4 includes a U-shaped seat 41. A third motor 42 is arranged on one side of the U-shaped seat 41. The output shaft of the third motor 42 is connected to a lead screw 43. A slide bar 44 is arranged inside the U-shaped seat 41. A slide seat 45 is sleeved on the slide bar 44 and the lead screw 43. When the third motor 42 works, it drives the lead screw 43 to rotate, so that the slide seat 45 slides along the slide bar 44.

[0040] Among them, the slide seat 45 is fixedly connected to the power frame 3, and the slide seat 45 drives the power frame 3 to slide synchronously along the slide bar 44.

[0041] Among them, when the position of the driving gear 32 is adjusted through the adjusting component 4 and the rewinding roller 5 is quickly replaced, the adjusting component 4 drives the driving gear 32 to retreat a certain distance for avoidance. At this time, the first base plate 11 can drive the driven gear 12 to rotate smoothly under the drive of the first motor 7, and at the same time move the driven gear 12 of another group of rewinding rollers 5 into the designated position. After the quick replacement of the rewinding roller 5 is completed, the adjusting component 4 drives the driving gear 32 to reset, so that the driving gear 32 meshes with the driven gear 12 again.

[0042] Among them, connection shafts 211 are welded and fixed on the outer side surfaces of the first base plate 11 and the second base plate 21.

[0043] Among them, the connecting shaft 211 is connected to the bearing bracket 6 through a bearing. The output shafts of the two groups of first motors 7 are respectively connected to the connecting shaft 211 of the first substrate 11 and the second substrate 21. The output shaft of the first motor 7 and the connecting shaft 211 are fixedly connected through a coupling. The first motors 7 on both sides work synchronously to drive the driven gear 12 and the fixed seat 22 to move synchronously. When the driven gear 12 and the fixed seat 22 move, the rewinding roller 5 between them moves synchronously.

[0044] Working principle: When the second motor 31 works, it drives the driving gear 32 to rotate. The driving gear 32 drives the driven gear 12 to rotate synchronously. The driven gear 12 drives the rewinding roller 5 to rotate. The rotating rewinding roller 5 rewinds the PE protective film. After the rewinding of the PE protective film outside one of the rewinding rollers 5 is completed, the cutting mechanism cuts the PE protective film. The adjusting assembly 4 drives the driving gear 32 to retreat a certain distance to avoid. The first motors 7 on both sides work synchronously to drive the driven gear 12 and the fixed seat 22 to move synchronously. When the driven gear 12 and the fixed seat 22 move, the rewinding roller 5 between them moves synchronously. The rewinding roller 5 after rewinding is moved out of the working position, and at the same time, a new rewinding roller 5 to be rewound is moved into the working position to realize the quick replacement of the rewinding roller 5 and quickly put it into use. After the quick replacement of the rewinding roller 5 is completed, the adjusting assembly 4 drives the driving gear 32 to reset, so that the driving gear 32 meshes with the driven gear 12 again. The rewinding roller 5 rotates and rewinds under the drive of the second motor 31. While the rewinding operation is in progress, the rewinding roller 5 after winding is removed and replaced after removal. The installation and disassembly method of the rewinding roller 5 is simple.

[0045] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
