Description

Technical Field

[0001] This utility model relates to the technical field of film production equipment, specifically to a material unloading device for a film winding machine. Background Technology

[0002] After the film winding machine winds the film into a cylindrical roll, the film roll needs to be unloaded from the rollers of the film winding machine. This process presents the following problems: 1. The film winding rollers need to be linked with the drive motor to achieve rotational film winding. After the film roll is on the rollers, it needs to slide along the axial groove of the rollers to complete the unloading. Therefore, in the design, one end of the roller needs to be able to be connected to the drive motor for transmission, and the film roll cannot slide out from this end. The other end needs to be able to maintain rotational engagement with the film winding machine frame during film winding, and also be able to separate from the film winding machine frame during unloading to allow the film roll to slide out. Therefore, the structure is complex and the operation steps are cumbersome. 2. When the film winding machine has multiple stations, that is, when it can wind two or more film rolls at the same time, if the unloading is done one roller at a time, it will lead to low operating efficiency.

[0003] Therefore, it is necessary to improve the structural design of the unloading device of the film roll machine to make the film roll unloading process convenient and reliable, and to enable multi-station linkage unloading. Utility Model Content

[0004] In order to overcome the shortcomings of the above-mentioned technology, this utility model provides a material unloading device for a film rolling machine.

[0005] The technical solution of this utility model is: a material unloading device for a film winding machine. The film winding machine includes a frame, a take-up roller shaft, a drive mechanism, and a support mechanism. The take-up roller shaft includes a drive end and a material unloading end. The drive end is rotatably engaged with the frame and linked with the drive mechanism. The support mechanism is located on one side of the material unloading end and is rotatably engaged with the material unloading end. The end face of the material unloading end is provided with an insertion groove. The unloading device includes a base, a movable seat, a column, a collar, a shaft assembly, and a first drive cylinder. The base is provided with a first slide rail, and the bottom surface of the movable seat is provided with a slider adapted to the first slide rail. The column is fixed on the movable seat, and the shaft assembly is fitted onto the column for selective engagement. The collar is fitted onto the column for axial fixation and supports the shaft assembly. The shaft assembly has a connecting shaft with a contour adapted to the insertion groove along its radial direction. The first drive cylinder is fixed on the base, and the piston rod of the first drive cylinder is connected to the movable seat. The drive connecting shaft is inserted into the insertion groove to connect with the unloading end of the winding roller shaft, or leaves the insertion groove.

[0006] Further features of this invention: The support mechanism includes a support frame and a second drive cylinder. The frame is provided with a second slide rail and a limiting block on one side of the unloading end. The support frame is provided with an opening groove facing the unloading end and with a suitable diameter. The support frame is provided with a slider adapted to the second slide rail. The second drive cylinder is fixedly connected to the frame, and its piston rod is connected to the support frame. The second drive cylinder drives the opening groove to cover the unloading end for selective engagement or disengagement. The second drive cylinder is linked with the first drive cylinder for signal-driven start and stop.

[0007] A further feature of this invention is that the support frame is provided with a piston hole extending through to one side of the opening slot, and the support mechanism also includes a third drive cylinder, which is fixed on the support frame and whose piston rod passes through the piston hole and enters and exits the opening slot to open and close the opening slot. The third drive cylinder is linked with the second drive cylinder and the first drive cylinder to start and stop.

[0008] A further feature of this invention is that a plurality of balls are provided on the outer circumferential surface of the take-up roller.

[0009] A further feature of this invention is that the film winding machine has two or more winding stations along the vertical direction, each winding station is provided with a winding roller shaft at intervals, and the column is provided with a number of shaft collars and shaft kits corresponding to the positions of each winding roller shaft.

[0010] The beneficial effects of this utility model are as follows: through the coordinated design of the frame, take-up roller, drive mechanism, support mechanism and unloading device of the film rolling machine, the drive end of the take-up roller does not need to be disassembled and can remain connected to the drive mechanism, while the unloading end can unload material through the alternating operation of the support mechanism and the unloading device.

[0011] For details, please refer to the attached instruction manual. Figure 1-3 As described above, when the take-up roller is winding the film, the unloading device moves away from the take-up roller. At this time, the second drive cylinder drives the opening slot of the support frame to engage with the unloading end, and the piston rod of the third drive cylinder intercepts the opening slot to prevent the unloading end from disengaging. Under the linkage of the drive mechanism, the take-up roller rotates to wind the film.

[0012] When the film roll is finished and unloading is required, the first drive cylinder of the unloading device drives the connecting shaft to insert into the insertion slot, forming a connection to support the unloading end of the take-up roller shaft. Then, the second and third drive cylinders work together to separate the support frame from the unloading end, as shown in the instruction manual. Figure 1 As shown, this connection structure allows the film roll to be unloaded without disassembling or moving the take-up roller. The film roll can slide axially along the roller provided on the outer circumference of the take-up roller.

[0013] As per the instruction manual Figure 2 As shown, the film roll slides into the connecting shaft, and then the support frame extends, with the opening slot fitting the unloading end.

[0014] As per the instruction manual Figure 3 As shown, after the support frame is fitted with the unloading end, the connecting shaft leaves the insertion slot, and the winding roller shaft continues to perform new winding work. The connecting shaft can rotate with the shaft assembly to facilitate subsequent operations.

[0015] Furthermore, the unloading device of this application can be equipped with multiple connecting shafts according to the working position of the film winding machine, so as to achieve one connection and disassembly of multiple film rolls. Attached Figure Description
