Description

Technical Field

[0001] The utility model relates to a winding bed of a printing machine. Background Art

[0002] After the printing press finishes printing, the winding roller is used for winding. The winding roller is generally connected to the motor through a coupling and is wound by the rotation of the motor. When the format of the printed material is wide, the required winding roller length is also relatively long. At this time, the winding roller will be continuously wound, resulting in an increase in overall weight, and the winding roller will be sunken toward the center, causing the coupling to get stuck and shortening the life of the machine. Therefore, the requirements for the driving equipment and supporting equipment of the winding roller are relatively high. At the same time, due to the long length of the winding roller, the installation and disassembly will also be cumbersome. During this process, the winding roller is not well supported and is easy to fall off and cause damage. Utility Model Content

[0005] An air charging head is arranged on the frame.

[0006] Side rollers are respectively arranged on both sides of the frame. The side rollers are arranged at the edges of the frame. The horizontal height of the side rollers is higher than that of the active roller and the driven roller.

[0007] The push plate is connected to the frame through an adjustable device.

[0008] A sticky rubber roller is arranged below the gap between the active roller and the driven roller, and the sticky rubber roller is in contact with the active roller and the driven roller.

[0009] The beneficial effects are as follows: the utility model has a reasonable and ingenious structural design, the winding roller is sleeved on the inflatable shaft, and through the friction between the active roller and the driven roller, it rotates under the drive of the active roller to achieve winding, because the winding roller is supported by the active roller and the driven roller as a whole, the roller body is not easy to deform, and at the same time the driven roller shares the pressure on the active roller, reducing the driving pressure on the motor, and the inflatable shaft is limited by the push plate, the winding roller is easy to install and disassemble, and it is not easy to fall.

[0016] like Figure 1 , Figure 2The printing press winding bed shown includes a frame 1, a driving roller 2 is arranged in the center of the frame 1, the driving roller 2 is driven by a motor 5, a driven roller 3 is arranged on both sides of the driving roller 2, an air shaft 7 is set in the gap between the driving roller 2 and the driven roller 3, the winding roller is sleeved on the air shaft 7, and the two ends of the air shaft 7 are clamped by two push plates 8, and the push plates 8 are connected to the frame 1. Due to the influence of the ultra-wide format of the printing material, the winding roller is relatively long, and is directly placed on the driven roller 3 and the driving roller 2, which bears the weight, and can play a role in uniformly supporting the winding roller, avoiding the deformation of the winding roller itself and the connecting parts caused by the increase of the overall weight during the winding process. After the driving roller 2 rotates, the winding roller and the driven roller 3 rotate simultaneously under the action of friction, thereby driving the winding roller to rewind, and multiple groups of winding operations can be carried out simultaneously on the entire frame 1, thereby improving work efficiency. After the push plate 8 clamps the two ends of the inflatable shaft 7, the inflatable shaft 7 will not deviate during the rotation process, and the installation and disassembly of the winding roller is more convenient, and only the push plate 8 needs to be separated from the inflatable shaft 7.

[0017] In order to facilitate the fixed connection between the inflatable shaft 7 and the winding roller, an inflation head 6 is arranged on the frame 1, and the inflation head 6 is connected to an air pump.

[0018] In order to prevent the winding roller with an increased diameter after winding from rolling off the frame 1, side rollers 4 are respectively arranged on the two side edges of the frame 1. The horizontal height of the side rollers 4 is higher than that of the active roller 2 and the driven roller 3. The side rollers 4 can support the front and rear sides of the winding roller. In order to facilitate the loading and unloading of the winding roller, the side rollers 4 can be connected to the frame 1 through a swing arm. One end of the swing arm is connected to the frame 1 through a rotating shaft, and the other end is connected to the side roller 4. Limit blocks are respectively arranged at the front and rear of the swing arm. The swing arm swings to move the horizontal position of the side roller 4 to a horizontal position lower than or equal to that of the active roller 2 and the driven roller 3. The winding roller can be loaded and unloaded by pushing the winding roller.

[0019] The push plate 8 is connected to the frame 1 through an adjustable device. The adjustable device is a cylinder. The push of the cylinder can clamp the inflatable shaft 7. Bearing seats are set at both ends of the inflatable shaft 7. Bearings are set in the bearing seats. After the push plate 8 clamps the inflatable shaft 7, the inflatable shaft 7 connected to the bearing seat can still rotate. The cylinder control has a high degree of automation, which is conducive to the improvement of the overall automation level. The adjustable device can be a gear and a rack. The push plate 8 is connected to the end of the rack. The rack is connected to the frame 1 through a fixed block. The rack can move back and forth on the fixed block. The gear connected to the frame 1 is meshed with the rack. During the rotation process, the rack drives the push plate 8 to move back and forth, and the tightness of the clamping between the push plate 8 and the inflatable shaft 7 can be accurately controlled. The gear can be controlled by a manual wheel or a motor. When the motor is controlled, the degree of automation can be improved.

[0020] A sticky rubber roller is provided below the gap between the driven roller 3 and the driving roller 2. The sticky rubber roller is a roller body with a sticky rubber layer attached to the surface. The surface of the sticky rubber roller contacts the surfaces of the driving roller 2 and the driven roller 3. During the rotation, the sticky rubber roller adheres to the dust on the surfaces of the driving roller 2 and the driven roller 3 to prevent dust impurities from adhering to the printed material on the winding roller. The sticky rubber roller can be replaced by a brush roller. The brush roller is a roller body with bristles attached to the surface. The bristles of the brush roller contact the surfaces of the driving roller 2 and the driven roller 3. The brush roller is connected to a driving motor and brushes away the dust on the surfaces of the driving roller 2 and the driven roller 3 during the rotation.

[0021] The utility model discloses the structure design is reasonable and ingenious, for the winding of ultra-wide printing materials, the active roller and the driven roller evenly support the winding roller, can ensure that the winding roller is not easy to deform, also reduces the occurrence of falling accidents during loading and unloading, improves safety, and at the same time the design of the push plate structure can facilitate the loading and unloading of the winding roller.
