Description

Technical Field

[0001] The utility model relates to a winding device, in particular to a three-mode winding device suitable for winding rollers of different sizes. Background Art

[0002] The winding device is one of the main functional equipment of the packaging and printing equipment, which is used to wind the finished sheet. At present, the main winding modes include center winding, gap winding, friction winding, etc. Center winding and gap winding are both driven by the power of the winding roller itself. Among them, gap winding requires sheet cutting and continuation, so a transition roller close to the winding roller but retaining the gap is usually provided in front of the winding roller of gap winding. The winding roller of friction winding does not rotate itself, but is driven by the friction force generated by the pressure fit between another power roller and the winding roller. The producer selects the appropriate winding equipment for winding operation according to the production requirements of different sheets. However, each winding equipment usually has only one winding mode. If the sheet with different winding methods is changed, the corresponding winding equipment also needs to be replaced.

[0003] In order to solve the above problems, the applicant has previously disclosed a three-in-one film blowing winding mechanism (Chinese patent document CN107572285A). This three-in-one film blowing winding mechanism sets an active friction roller and sets the winding shaft to be movable, and selects the tension cylinder or displacement mechanism to drive the winding shaft close to or away from the active friction roller, and cooperates with the action of the winding motor to realize friction winding, gap winding, center and friction winding. Three winding modes are integrated, and a single winding machine can meet the winding needs of films of different specifications. However, in actual applications, due to the different distances between winding rollers of different sizes (such as 3-inch rollers or 6-inch rollers) and the active friction roller, the initial position of the winding roller when switching between various winding modes is different, and the position of the winding roller needs to be adjusted additionally. Summary of the invention

[0004] The problem to be solved by the utility model is to provide a three-mode winding device suitable for winding rollers of different sizes. The three-mode winding device suitable for winding rollers of different sizes has three winding modes and can switch the initial position of the winding roller according to the size of the winding roller. The technical solution adopted is as follows:

[0005] A three-mode winding device suitable for winding rollers of different sizes, comprising a frame, a winding roller, a winding drive motor, a friction roller, a friction drive motor, a translation seat, a translation guide rail, a translation drive mechanism and a tensioning cylinder; both ends of the friction roller are rotatably mounted on the frame, the friction drive motor is mounted on the frame, and one end of the friction roller is transmission-connected to the output shaft of the friction drive motor; the translation guide rail is horizontally arranged on the frame, one end of the translation guide rail corresponds to the friction roller, the translation seat is mounted on the translation guide rail and can move along the translation guide rail, and the translation seat is connected to the power output end of the translation drive mechanism; the cylinder body of the tensioning cylinder is horizontally mounted on the frame, and the piston rod of the tensioning cylinder is connected to the translation seat; the winding roller and the winding drive motor are both mounted on the translation seat, and the winding drive motor is transmission-connected to one end of the winding roller through a clutch; it is characterized in that: the three-mode winding device is also provided with a position switching device, the position switching device is mounted on the frame, and the translation seat is connected to the power output end of the position switching device.

[0006] The above-mentioned translation drive mechanism is used to drive the translation seat to translate along the translation guide rail, so that the winding roller is close to or away from the friction roller; the translation drive mechanism can usually adopt the method of a translation drive motor driving a synchronous belt, specifically including a translation drive motor, a synchronous belt, a driving wheel, and multiple driven wheels, the translation drive motor is arranged on a frame, the driving wheel and each driven wheel can be rotatably mounted on the frame, the driving wheel is connected to the output shaft of the translation drive motor, the driving wheel and each driven wheel tensions the synchronous belt, the translation seat is connected to the synchronous belt, and the synchronous belt is driven by the translation drive motor to drive the translation seat along the translation guide rail to adjust the relative distance between the winding roller and the friction roller.

[0007] The friction drive motor is used as a power source for the friction roller to drive the friction roller to rotate; the friction drive motor is usually provided with a corresponding reducer.

[0008] The clutch is used to connect or disconnect the winding roller and the winding drive motor: when center winding or gap winding is performed, the clutch is closed, and the winding roller is connected to the winding drive motor; when friction winding is performed, the clutch is disconnected, and the winding roller and the winding drive motor are disconnected. The clutch can refer to the prior patent document of the applicant with publication number CN107572285A.

[0009] The position switching device is used to switch the initial position of the translation seat on the translation guide rail according to the different sizes of the winding roller before performing the corresponding winding operation.

[0010] The tensioning cylinder pulls the translation seat in the opposite direction in the state of friction winding and center winding, so that the winding roller and the friction roller are in contact.

[0011] The three-mode winding device of the utility model has three winding modes: center winding, gap winding and friction winding. Specifically:

[0012] (1) When center winding is performed, after the winding roller is installed and fixed, the position switching device drives the translation seat to move to the initial position of the winding roller according to the size of the winding roller, and the clutch is closed, so that the winding drive motor is connected to the winding roller; then, the translation drive mechanism drives the translation seat to move along the translation guide rail, so that the winding roller and the friction roller are in contact, and then the translation drive mechanism is stopped, and the tensioning cylinder tightens the winding roller to make it fit the friction roller and maintain a fixed pressure; during the entire winding process, the winding drive motor drives the winding roller to actively wind, and the friction roller plays a friction-assisted winding role in the winding process;

[0013] (2) When gap winding is performed, after the winding roller is installed and fixed, the position switching device drives the translation seat to move to the initial position of the winding roller according to the size of the winding roller, and the clutch is closed, so that the winding drive motor is connected to the winding roller; then, the translation drive mechanism drives the translation seat to move along the translation guide rail to ensure that the winding roller is close to the friction roller but retains the gap; during the entire winding process, the tension cylinder pressure relief loses its function, and the winding drive motor drives the winding roller to actively wind, and the friction roller assists in the cutting and splicing of the sheet during the gap winding process;

[0014] (3) When friction winding is performed, after the winding roller is installed and fixed, the position switching device drives the translation seat to move to the initial position of the winding roller according to the size of the winding roller, and the clutch is disconnected; then, the translation drive mechanism drives the translation seat to move along the translation guide rail to make the winding roller fit with the friction roller, and then the translation drive mechanism is stopped, and the winding roller and the friction roller are fit together by the tensioning cylinder; during the entire winding process, the tensioning cylinder tightens the winding roller to fit with the friction roller and maintains a fixed pressure, and the friction drive motor drives the friction roller to rotate, so that the winding roller passively rotates for winding.

[0015] In order to improve the movement accuracy of the initial position of winding rollers of different sizes, the translation seat can be quickly moved to the initial position of winding rollers of different sizes before installing the winding rollers. As a preferred solution of the utility model, the position switching position is a multi-position cylinder, the cylinder body of the multi-position cylinder is horizontally installed on the frame, and the piston rod of the multi-position cylinder is connected to the translation seat; each workstation of the multi-position cylinder corresponds to each winding roller of different sizes.

[0016] In actual winding operations, winding rollers with three-inch shafts or six-inch shafts are mainly used for winding. Therefore, as a further preferred embodiment of the present invention, the position switching device is a double-station cylinder.

[0017] As another preferred solution of the utility model, the tensioning cylinder is a multi-position cylinder, and the tensioning cylinder also serves as the position switching device. When the control accuracy allows, the tensioning cylinder adopts a multi-position cylinder and is also used as a position switching device: before installing the winding roller, the translation seat is moved to the initial position of the winding rollers of different sizes; when performing center winding or friction winding, the winding roller is tightened to fit the friction roller and maintain a fixed pressure.

[0018] Compared with the prior art, the utility model has the following advantages:

[0019] The utility model is suitable for adding a position switching device to a three-mode winding device with winding rollers of different sizes. When the three winding modes are provided, the initial position of the translation seat on the translation guide rail can be switched according to the different sizes of the winding rollers, so as to facilitate the winding operation at the accurate initial position.
