The film roll conveyor provided by the present invention comprises a moving mechanism, a lifting mechanism and a transport frame. By setting up the moving mechanism, the transport frame can be driven to move through the moving mechanism to match the production lines at different positions. By setting up the lifting mechanism, the transport frame can be driven to rise and fall through the lifting mechanism, thereby changing the height of the film roll, and the application range is wide. By making the auxiliary frame of the transport frame rotatably set on the lifting plate of the lifting mechanism, the auxiliary transport rollers can be rotatably mounted on the auxiliary frame, and the auxiliary transport rollers can support the two sides of the film roll to prevent it from tipping over through the rotation of the auxiliary frame. During the transportation, no damage is caused to the two sides of the film roll. By setting up a transmission mechanism and using the transmission mechanism to connect the support arm of the lifting mechanism and the auxiliary frame, when in use, the support arm of the lifting mechanism will drive the auxiliary frame to rotate upward when it is unfolded, so that the auxiliary support rollers support the two sides of the film roll, which is easy to use.

Description

Technical Field

[0001] The invention relates to the field of conveying devices, and in particular to a film roll conveyor. Background Art

[0002] Roll film is a general term for packaging film supplied in rolls in the packaging industry. During transportation, since the roll film can rotate around its own axis, it is unstable and prone to rollover. Most existing roll film conveyors block the roll film by setting baffles on both sides of the roll film. However, the two sides of the roll film will form dry friction with the baffles, causing damage to the roll film. In addition, most existing roll film conveyors do not have the function of moving and lifting, and it is difficult to change the position to match different assembly lines, and it is also difficult to change the height of the roll film, and the scope of application is narrow.

[0027] The up and down directions described in the present invention refer to Figure 1 The up and down directions in .

[0028] like Figure 1-3 As shown, the roll film conveyor provided by the present invention comprises: a moving mechanism 10, a lifting mechanism 20, a transport frame 30 and a transmission mechanism 40, wherein the moving mechanism 10 comprises a base plate 11, a caster 12 located at the bottom of the base plate 11, and a motor 13 for driving the caster 12 to rotate; the lifting mechanism 20 is arranged on the base plate 11, and the lifting mechanism 20 comprises a lifting plate 21, a support arm 22 and a hydraulic cylinder 23, the lifting plate 21 is located above the support arm 22, and the support arm 22 has an extended state and a retracted state, and when the support arm 22 is in the extended state, the lifting plate 21 is located above the support arm 22, and the support arm 22 has an extended state and a retracted state.

The main frame 31 is provided with a rotatable main transport roller 33, and the rotation axis center line of the main transport roller 33 is parallel to the horizontal plane, and the rotation axis center line of the main transport roller 33 is in the same direction as the moving direction of the roll film. The auxiliary frame 32 is vertically provided with a rotatable auxiliary transport roller 34, the rotation axis of the auxiliary transport roller 34 is perpendicular to the moving direction of the roll film, the inner side of the auxiliary frame 32 is rotatably connected to the lifting plate 21, and the auxiliary frame 32 has a first working position and a second working position. When the auxiliary frame 32 is in the first working position, a part of the auxiliary transport roller 34 is located above the highest point of the main transport roller 33. The main transport roller 33 is used to support the bottom of the roll film and drive the roll film to move, and the auxiliary transport roller 34 is used to support both sides of the roll film to prevent the roll film from tipping over. When the auxiliary frame 32 is in the second working position, all the auxiliary transport rollers 34 are located below the highest point of the main transport rollers 33; the main transport rollers 33 and the auxiliary transport rollers 34 are alternately distributed, and there is a gap 35 between adjacent main transport rollers 33 and auxiliary transport rollers 34; the transmission mechanism 40 is connected to the support arm 22 and the auxiliary frame 32, and when the support arm 22 is changed to the extended state, the transmission mechanism 40 drives the auxiliary frame 32 to rotate to the first working position, and when the support arm 22 is changed to the folded state, the auxiliary frame 32 rotates to the second working position under the action of gravity.

[0029] In this embodiment, there are multiple main transport rollers 33 and auxiliary transport rollers 34 , the spacing between adjacent main transport rollers 33 is equal, the spacing between adjacent auxiliary transport rollers 34 is equal, and the auxiliary transport roller 34 is located in the middle position between two adjacent main transport rollers 33 .

[0030] In order to facilitate the rotation of the main transport roller 33 and not interfere with the rotation of the auxiliary frame 32, an annular groove 331 is provided in the middle of the main transport roller 33. External power drives the main transport roller 33 to rotate through the annular groove 331. This power transmission method can be achieved by synchronous belt drive, chain drive, etc., which will not be repeated here. It should be noted that all the main transport rollers 33 keep rotating synchronously.

When the support arm 22 is changed to the expanded state, the support arm 22 lifts the lifting plate 21 and drives the auxiliary frame 32 to rise synchronously to the first working position. When in the expanded state, the support arm 22 drives the first transmission member 41 to move leftward, and drives the second transmission member 42 to move upward through the first transmission member 41, so that the auxiliary frame 32 rotates to the first working position.

When the support arm 22 is changed to the unfolded state, the lower end of the outer support rod 222 slides to the left relative to the base plate 11, tightens the brake rope 24, and brakes 121 to ensure that the roll film conveyor cannot move. When the support arm 22 is changed to the folded state, the lower end of the outer support rod 222 slides to the right relative to the base plate 11, the brake 121 is released, and the roll film conveyor can move.

[0034] Due to the implementation of the above technical solution, the present invention has the following advantages compared with the prior art:

After use, the support arm of the lifting mechanism is folded, and the auxiliary support rollers rotate downward under the action of their own weight, so that the auxiliary support rollers fall back below the main support rollers, which is convenient for storage and easy to use.
