[0002] The sealing machine, also known as the center sealing glue coating machine, is a device specially used to seal and form shrink film materials such as PVC, PETG, OPS, etc. into roll-shaped materials.

[0003] The current roll-changing operation steps of the hand-jointed machine are: stop the equipment and ensure that the old roll stops rotating; remove the couplings at both ends of the roller shaft and remove the roller shaft with the old roll; remove the old roll on the roller shaft, replace it with a new roll and fix the new roll; install the roller shaft with the new roll back to the hand-jointed machine and reconnect it using the coupling; start the equipment and run it again.

[0004] It can be seen that the current coil changing steps of the coupling machine are relatively complicated, requiring workers to constantly disassemble the coupling. Not only is the process cumbersome and time-consuming, affecting production progress, but it also increases the workload of workers.

[0027] The outer periphery of the roller shaft 2 is fixedly connected with a limiting ring 1 21 and screwed with a limiting ring 22, and the distance between the limiting ring 1 21 and the limiting ring 22 is adapted to the width of the coil 7;

[0028] In addition, driving members 3 are installed at the positions of both ends of the roller shaft 2 of the hand-closing machine body 1, and the output shaft of the driving member 3 is provided with a connecting component 4; one end of the connecting component 4 is connected to the output shaft of the driving member, and the other end passes through the hand-closing machine body 1 and is connected to the end of the roller shaft 2;

[0029] Specifically, the connecting component 4 includes a bearing 41, and the bearing 41 includes an inner shaft, a ball and an outer shaft; a plurality of connecting rods 42 are provided between the outer shaft and the output shaft of the driving member 3 to connect the two; a spline 43 is connected to the end of the inner shaft away from the driving member 3, and both ends of the roller shaft 2 are provided with a keyway 23 that cooperates with the spline 43; in this way, when the coil 7 needs to be replaced, by controlling the output shaft of the driving member 3 to retract, the connecting rod 42 drives the bearing 41 and the spline 43 connected to the outer shaft of the bearing 41 to move synchronously, so that the spline 43 is disengaged from the keyway 23 of the roller shaft 2, and the two ends of the roller shaft 2 lose the support of the spline 43 and fall from the hand-closing machine body 1, thereby completing the automatic disassembly of the roller shaft 2, without the need for workers to frequently disassemble the coupling, thereby improving production efficiency and reducing the labor of workers.

[0030] See also Figure 1 Specifically, a mounting seat 11 is provided at a position of the handheld machine body 1 corresponding to the driving member 3 , and the driving member 3 is mounted on the mounting seat 11 .

[0031] See also Figure 1 Specifically, the utility model also includes a bracket 5, on which a rotating wheel 51 is rotatably connected, and a plurality of roll-changing groups are arranged on the periphery of the rotating wheel 51; the roll-changing group includes support arms 52 installed at both ends of the rotating wheel 51, and the ends of the two support arms 52 are connected with hard rubber buckles 53 whose inner diameters match the roller shaft 2; in addition, an auxiliary frame is connected to the side of the bracket 5, and a driving member 2 6 is installed on the top of the auxiliary frame, and the output shaft of the driving member 2 6 is connected to the rotating wheel 51, and the axis of the output shaft of the driving member 2 6 coincides with the axis of the rotating wheel 51; in this way, in the old While the roll is still in use, the worker can first install the new roll on the roller shaft 2, and then clip the two ends of the roller shaft 2 into the hard rubber buckles 53. When the roller shaft 2 with the old roll is automatically unloaded from the closing machine, the worker operates the output shaft of the driving member 2 6 to rotate, so that the roller shaft 2 with the new roll is rotated to the position of the roller shaft 2 originally equipped with the old roll, and then operates the driving member 1 3 to assemble the spline 43 of the driving member 1 3 with the keyway 23 of the roller shaft 2 with the new roll, thereby completing the automatic replacement of the roll material 7 of the closing machine, reducing manpower consumption and improving production efficiency.

[0032] Preferably, the driving member 2 6 is a brake motor, also known as an electromagnetic power-off brake motor or a brake asynchronous motor, which is a prior art; when it is powered on, the electromagnet is energized and attracted, and the motor does not produce a braking effect at this time; and when the motor is powered off, the electromagnet is also powered off, and at this time, under the action of the spring, the brake device will brake the motor, thereby achieving mechanical self-locking; thereby ensuring that the shaft will not rotate accidentally when the spline 43 of the driving member 3 and the keyway 23 of the roller shaft 2 are assembled.

[0033] It should be noted that the driving member 3 of the present invention is an electric telescopic rod, and those skilled in the art may select other driving members 3 according to actual conditions.

[0034] It should be noted that the present invention has three roll changing groups, and those skilled in the art can set other numbers of roll changing groups on the periphery of the rotating wheel 51 according to actual conditions.

[0035] The working process of the utility model is:

[0036] First: during the use of the old roll, the worker installs the new roll on the roller shaft 2 , and then clips the two ends of the roller shaft 2 with the new roll into the hard rubber buckles 53 .

[0037] Second: control the output shaft of the driving member 3 to retract, the output shaft of the driving member 3 synchronously drives the connecting rod 42 to move, the connecting rod 42 drives the bearing 41 and the spline 43 connected to the outer shaft of the bearing 41 to move synchronously, the spline 43 escapes from the keyway 23 of the roller shaft 2, and the two ends of the roller shaft 2 lose the support of the spline 43 and fall off the hand-closing machine body 1, and the automatic disassembly of the roller shaft 2 is completed.

[0038] Third: After the roller 2 is automatically disassembled, the worker operates the output shaft of the driving member 2 6 to rotate, so that the roller 2 equipped with the new roll is rotated to the position of the roller 2 originally equipped with the old roll; then the driving member 2 6 is closed, and then the driving member 1 3 is operated, so that the output shaft of the driving member 1 3 pushes the spline 43 and the keyway 23 of the roller 2 equipped with the new roll for assembly.

[0039] Fourth: After the new roll is assembled, the roller 2 with the new roll is still stuck in the hard rubber buckle 53; at this time, the worker starts the driving member 2 6 again, and at the same time operates the output shaft of the driving member 2 6 to rotate; because the roller 2 with the new roll has been limited by the spline 43, when the output shaft of the driving member 2 6 rotates, the hard rubber buckle 53 will gradually peel off from the roller 2, and the worker can process the new roll after the hard rubber buckle 53 and the roller 2 are completely peeled off.

[0040] In summary, the utility model provides an automatic roll-changing device for a hand-jointed machine, which controls the output shaft of the driving member 1 to retract, so that the connecting rod drives the bearing and the spline connected to the outer shaft of the bearing to move synchronously, so that the spline is disengaged from the keyway of the roller shaft, and the two ends of the roller shaft lose the support of the spline and fall from the hand-jointed machine body, thereby completing the automatic disassembly of the roller shaft, eliminating the need for workers to frequently disassemble the coupling, thereby improving production efficiency and reducing the labor of workers; by setting up a roll-changing group, workers can first install the new roll on the roller shaft, thereby shortening the installation time of the new roll; and when the old roll is removed, the worker can operate the output shaft of the driving member 2 to rotate to quickly replace the roller shaft with the new roll, thereby reducing the labor of workers and improving production efficiency.

[0041] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field can make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims attached to the present invention.
