Description

Technical Field

[0001] This utility model relates to the field of winding device technology, and in particular to a manual winding device for test paper rolls. Background Technology

[0002] Paper production involves multiple processes, one of which is rewinding, where finished paper or slit paper is rewound into a roll. A rewinding device is an essential piece of equipment in this process. Existing rewinding devices generally consist of an unwinding mechanism, a conveying mechanism, and a rewinding mechanism. They are widely used in the rewinding processes of fabrics, films, and paper. However, existing rewinding devices require operators to measure the material being rewound, stop the machine, manually cut the material, and change the roll. Simultaneously, operators need to manually adjust the conveying mechanism to regulate the tension during material collection, resulting in low work efficiency.

[0003] The aforementioned existing technical solutions have the following drawbacks: When performing manual winding, the staff needs to pay attention to the winding length at all times to prevent it from being too long or too short and affecting subsequent use. However, human observation cannot accurately control the length to the required target length. Furthermore, the staff will feel tired after working for a long time during manual winding. The existing manual winding devices are not labor-saving enough. Utility Model Content

[0004] The purpose of this invention is to provide a manual roll-up device for test paper to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A manual roll rewinding device for test strips includes a base and further includes:

[0007] A winding module is fixedly mounted on the top of the base. The winding module includes a manual drive device and a first rotating shaft. The manual drive device includes a bracket, a rotating handle, a first gear, a second rotating shaft, a second gear, a third gear, a third rotating shaft, and a fourth gear. The third rotating shaft is rotatably mounted at both ends of the bracket and has an extension penetrating the front end of the bracket. The first gear is fixedly mounted on the extension of the third rotating shaft. The rotating handle is fixedly mounted on the top of the extension of the third rotating shaft and is connected to the first gear. The second rotating shaft is spaced above the third rotating shaft and rotatably mounted at both ends of the bracket. The front and rear ends of the second rotating shaft are provided with… The second gear is sleeved on the extension of the second rotating shaft at the front end, and the third gear is sleeved on the extension of the second rotating shaft at the rear end. The first rotating shaft is spaced above the second rotating shaft and is rotatably mounted with the bracket. The front and rear ends of the first rotating shaft are provided with extensions that penetrate the bracket. The fourth gear is sleeved on the extension of the rear end of the first rotating shaft. The extension of the rear end of the first rotating shaft is sleeved with a winding wheel. The front and rear sides of the winding wheel are provided with a first limiting plate and a second limiting plate. The first gear and the second gear mesh and drive each other. The third gear and the fourth gear mesh and drive each other. The second gear and the third gear are connected in a driving connection. The front part of the first gear is provided with a distance fixing device.

[0008] The supply module is spaced to the right of the winding module. The supply module includes two sets of support rods, a fourth rotating shaft, a third limiting plate, and a fourth limiting plate. The fourth rotating shaft is rotatably installed at the front and rear ends of the support rods. The third and fourth limiting plates are sleeved on the fourth rotating shaft.

[0009] By adopting the above technical solution, the setting of the distance fixing device will lock the entire device after the target length is reached, so that the winding length always hovers within the required length range, and will not affect subsequent use due to the winding length being too long or too short.

[0010] In a further embodiment, the diameter of the first gear is larger than that of the second gear, and the diameter of the third gear is larger than that of the fourth gear.

[0011] By adopting the above technical solution, due to the difference in gear diameter, when manually winding, the operator only needs to apply a small force to drive it. With the replacement of the gears, the applied force will make the winding shaft rotate more times, thus achieving the purpose of saving effort.

[0012] In a further embodiment, the first limiting plate is fixedly mounted on the first rotating shaft, the second limiting plate is movably mounted on the first rotating shaft, and the second limiting plate moves axially along the front-back direction of the first rotating shaft. The third limiting plate is fixedly mounted on the fourth rotating shaft, the fourth limiting plate is movably mounted on the fourth rotating shaft, and the fourth limiting plate moves axially along the front-back direction of the fourth rotating shaft.

[0013] By adopting the above technical solution, the design of the movable limiting plate allows the device to simply adjust the movable limiting plate when dealing with test rolls of different sizes, so that it can rewind test rolls of different sizes without having to change the rewinding device because of different sizes.

[0014] In a further embodiment, the first limiting plate and the third limiting plate are located on the same axis in the left-right direction.

[0015] By adopting the above technical solution, the problem of test paper rolls breaking or misaligning during the winding process will not occur due to the inconsistent positions of the supply module and the winding module.

[0016] In a further embodiment, the handheld portion of the rotating handle is fitted with an anti-slip sleeve.

[0017] By adopting the above technical solution, staff will not injure themselves due to slippage when cranking the handle, and the test strip roll will not be affected by the staff's slippage during winding.

[0018] In a further embodiment, the top of the base is provided with a groove for placing the rolled-up test paper roll.

[0019] By adopting the above technical solution, the rolled-up test papers can be easily sorted and placed.

[0020] In a further embodiment, the left tooth surface of the first gear, the second gear, the third gear, and the fourth gear is steep while the right tooth surface is gentle.

[0021] By adopting the above technical solution, the gears will not reverse due to inertia or other forces, thus affecting the winding of the test strip roll.

[0022] In summary, this utility model has the following beneficial effects:

[0023] 1. The fixed-distance device ensures that the winding length is maintained within the required range; the different gear diameters reduce effort during transmission; the movable limit plate allows for winding different sized test rolls without needing to change the device; and the anti-slip handle prevents accidental winding of the test rolls due to slippage by the operator.
