Description

Technical Field

[0001] The utility model relates to the technical field of flat laminating machines, in particular to a fast film changing mechanism for flat laminating machines. Background Art

[0002] The laminating machine is a mechanical equipment for laminating and laminating various flat panels and pressing UV varnish. It is suitable for PVC boards, KT boards, melamine boards, bamboo fiberboards, rock boards, tiles, artificial stones, glass magnesium boards, aluminum honeycomb boards, calcium silicate boards, metal boards, stainless steel boards, aluminum boards, aluminum-plastic boards, UV paint boards, iron boards, decorative boards and other boards.

[0003] An existing fast film changing mechanism for a flat laminating machine (publication number: CN217807651U) has at least the following disadvantages: the above-mentioned device manually takes out the used film roller on the receiving frame, and then pushes the film roller on the frame into the receiving frame for replacement through a pushing mechanism, and the partition component separates the film roller on the frame. However, during the film changing process, the partition component only limits the rear side of the film roller on the frame, but does not limit the front side. Moreover, the rear side of the film roller on the receiving frame is not limited, which may easily cause the film roller to be squeezed and shaken during the film changing process, thereby reducing the stability of the device during operation, resulting in poor film changing effect. For this reason, we propose the utility model. Utility Model Content

[0023] In this embodiment, two mounting plates 3 are fixed to the front side of the fixing frame 1, and a mounting hole 301 is provided on the top surface of the mounting plate 3, and a fixing notch 302 is provided on the top surface of the mounting plate 3, and the fixing notch 302 is connected to the mounting hole 301. A rotating shaft 303 is rotatably provided inside the two mounting holes 301, and a limit rod 304 is fixed to the outer circumferential wall surface of the rotating shaft 303. The top surface of the mounting plate 3 is an inclined surface, and a transmission rod 306 is provided below the mounting plate 3, and one end of the two rotating shafts 303 away from each other and one end of the transmission rod 306 are fixed. There is a gear 305, the gear 305 on the rotating shaft 303 and the gear 305 on the transmission rod 306 are arranged up and down, and a toothed belt 307 is meshed between the upper and lower gears 305. A first motor is fixed to one end of the transmission rod 306, and a second motor is fixed to one side of the mounting frame 204. The output end of the second motor passes through one side of the mounting frame 204 and is fixed to one end of the screw 205. Through the setting of the film replacement structure, after the film roller 201 in the fixed notch 302 is used, the first motor drives the transmission rod 306 to rotate, and the film roller 201 in the fixed notch 302 is used. 07, the lower rotating shaft 303 rotates accordingly, so that the limiting rod 304 enters the mounting hole 301, and the used film roller 201 rolls along the inclined surface to one side of the mounting plate 3, and the first motor is reversed to make the limiting rod 304 rotate out of the mounting hole 301, and then the second motor is started to drive the screw rod 205 to rotate so that the slider 206 drives the pushing frame 202 to move toward the front side of the fixing frame 1. When the pushing frame 202 moves, the film roller 201 on the fixing frame 1 moves toward the front side of the fixing frame 1 under the action of the limiting notch 203, and the limiting notch 203 The film roller 201 on the fixed frame 1 is limited so that it will not be squeezed and shaken during the movement. When the film roller 201 located at the front side moves to the mounting plate 3, it rolls into the fixed notch 302 along the inclined surface of the mounting plate 3. The limiting rod 304 and the fixed notch 302 limit the front and rear sides of the film roller 201 so that it will not shake during use. In the above manner, the platform machine does not need to manually remove the used film roller 201 during the film changing process, and at the same time improves the stability of the device during the film changing process and enhances the film changing effect.

[0024] In this embodiment, an electric push rod 4 is fixed to the top surface of the slider 206, and the telescopic end of the electric push rod 4 is fixed to the inner bottom surface of the pushing frame 202. When the limiting notch 203 on the bottom surface of the pushing frame 202 limits the film rollers 201 of different diameters, the staff can drive the pushing frame 202 to rise and fall by the electric push rod 4, so that the limiting notch 203 can limit the film rollers 201 of different diameters. At the same time, when the film roller 201 in the movable hole 2 is used up, the staff can raise the pushing frame 202 to put the film roller 201 into the movable hole 2, and then lower the pushing frame 202 to limit the new film roller 201.

[0025] In this embodiment, a fixed shell 5 is fixed on the side of the two mounting plates 3 that are away from each other, the first motor is fixed to one side of the fixed shell 5, the gear 305 and the toothed belt 307 are both located in the fixed shell 5, and the fixed shell 5 can protect the gear 305 and the toothed belt 307 and prevent the staff from accidentally touching them.

[0026] In this embodiment, one side of the limiting rod 304 is an arc surface, and the inner wall surfaces of the fixed notch 302 and the limiting notch 203 are both arc surfaces. The arc surface design of the limiting rod 304, the fixed notch 302 and the limiting notch 203 can make them better adapt to the outer circular wall surface of the film roller 201 to ensure the limiting effect.

[0027] In this embodiment, a placement plate 6 is fixed to one side of the mounting plate 3. The placement plate 6 is L-shaped. When the used film roll 201 rolls out from the mounting plate 3, the placement plate 6 places it centrally for the convenience of subsequent processing by the staff.

[0028] The working principle is as follows: in use, after the film roller 201 in the fixed notch 302 is used, the staff starts the first motor to drive the transmission rod 306 to rotate, and the rotating shaft 303 follows the rotation under the transmission of the gear 305 and the toothed belt 307, so that the limiting rod 304 enters the mounting hole 301, and the used film roller 201 rolls along the inclined surface to one side of the mounting plate 3, and the first motor is reversed to make the limiting rod 304 rotate out of the mounting hole 301, and then the second motor is started to drive the screw rod 205 to rotate so that the slider 206 drives the pushing frame 202 to move toward the front side of the fixed frame 1. When the pushing frame 202 moves, the film roller 201 on the fixed frame 1 moves toward the front side of the fixed frame 1 under the action of the limiting notch 203, and the limiting notch 203 limits the film roller 201 on the fixed frame 1 so that it will not be squeezed and shaken during the movement. When the film roller 201 located at the front side moves to the mounting plate 3, it rolls into the fixed frame 3 along the inclined surface of the mounting plate 3. The limit rod 304 and the fixed notch 302 are limited at the front and rear sides of the film roller 201 in the notch 302, so that it will not shake during use. When the used film roller 201 rolls out from the mounting plate 3, the placement plate 6 places it centrally for the convenience of the staff to handle it later. The staff can drive the pushing frame 202 to rise and fall by the electric push rod 4, so that the limit notch 203 can limit the film rollers 201 of different diameters. At the same time, when the film roller 201 in the movable hole 2 is used up, the staff can raise the pushing frame 202 to put the film roller 201 into the movable hole 2, and then lower the pushing frame 202 to limit the new film roller 201. The gear 305 and the toothed belt 307 can be protected by the fixed shell 5, and at the same time, the staff can be prevented from accidentally touching them. The arc surface design of the limit rod 304, the fixed notch 302 and the limit notch 203 can make it better adapt to the outer circular wall surface of the film roller 201 to ensure the limiting effect.
