Description

Technical Field

[0001] The utility model relates to an open-width rubber strip roller, in particular to an open-width rubber strip roller used for a printing press. Background Art

[0002] During the printing process of the printing press, the printing material is transmitted between various rollers. Due to the soft material or the transmission error between the rollers, the printing material may be wrinkled when entering the printing roller, resulting in printing waste and reducing the yield rate. Therefore, it is necessary to open the width of the printing material before it enters the printing roller to keep the printing material flat. Generally, a rubber strip roller is used for opening the width. There are several rubber strips distributed in a ring shape on the outer side of the roller shaft of the rubber strip roller. By controlling the tension of the rubber strip, the roller surface of the rubber strip roller has a certain arc. The friction between the printing material and the rubber strip is used to make the printing material naturally open and flatten when passing through the rubber strip roller. However, the width of some packaging materials is relatively wide, so the width of the rubber strip roller adapted to it needs to be relatively wide. At this time, the required rubber strip is relatively long. Since there is no support in the center of the rubber strip, its material itself is relatively soft in order to adjust the tension. When its length is too long and the tension is small, the central support force of the rubber strip is weak, and the printing material cannot be flattened. At the same time, the distortion of the rubber strip may cause new wrinkles in the printing material. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings, the utility model provides an opening rubber strip roller, which can make the rubber strip on the rubber strip roller have supporting force and ensure the opening effect.

[0004] To achieve this purpose, the structure adopted by the utility model is: an open-width rubber strip roller, including a main shaft, bearing seats are respectively arranged at both ends of the main shaft, bearings are arranged in the bearing seats, the two ends of the main shaft are connected to the bearings, the outer side of the main shaft is annularly provided with multiple rubber strips, the two ends of the rubber strips are connected to the adjusting disk through screws and nuts, the adjusting disk is arranged at both ends of the main shaft, and multiple adjusting screws are arranged on the bearing seats and connected to the adjusting disk; multiple support plates are arranged in the center of the main shaft, the support plates are connected to one or more rubber strips, and the support plates are connected to the main shaft through elastic support members.

[0005] The elastic supporting member is a spring or an elastic connecting rod.

[0006] The support plate is a long arc-shaped plate. The support plate and the rubber strip are perpendicular to each other, and each support plate is connected to 3 to 5 rubber strips.

[0007] The elastic support member comprises two symmetrically arranged arc-shaped plastic rods, which are arranged in an arch shape, with two ends of the bottom connected to the main shaft and the top connected to the support plate.

[0008] The beneficial effects are as follows: the structural design of the utility model is reasonable and ingenious, the support plate connects several adjacent rubber strips, the elastic support part at the bottom of the support plate is connected to the main shaft, and provides support force for the center of the rubber strip. At the same time, because it can be elastically deformed, the tension of the rubber strip can be adjusted by adjusting the screws at both ends of the rubber strip, so that the center of the rubber strip always maintains a certain support force, avoiding the rubber strip roller from collapsing in the center when the rubber strip tension is small due to the wide width of the rubber strip roller.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0015] In the description of the utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components; the fixed connection can be welding or gluing. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0016] like Figure 1The open-width rubber strip roller shown includes a main shaft 1, bearing seats 2 are respectively arranged at both ends of the main shaft 1, bearings are arranged in the bearing seats 2, and the bearings are connected at both ends of the main shaft 1. The outer side of the main shaft 1 is provided with multiple rubber strips 4 in an annular shape, and the two ends of the rubber strip 4 are connected to the adjustment disk 3 through screws and nuts. The adjustment disk 3 is arranged at both ends of the main shaft 1. Multiple adjusting screws 5 are arranged on the bearing seat 2. The adjusting screws 5 are connected to the adjustment disk 3. The adjusting screws 5 are rotated to make them extend and retract to control the angle of the adjustment disk 3, thereby controlling the tension of the connected rubber strip 4. Multiple support plates 6 are arranged in the center of the main shaft 1. The support plates 6 are connected to one or more rubber strips 4, and the support plates 6 are connected to the main shaft through elastic support members 7. The elastic support member 7 is a structure with elastic deformation. The elastic support member 7 and the support plate 6 are used to provide elastic support to the center of the rubber strip 4 to prevent the rubber strip 4 from collapsing due to too low tension and failing to achieve the function of opening the width.

[0017] The elastic support member 7 can be a spring or an elastic metal rod, an elastic plastic rod, etc. Ear blocks are arranged on both sides of the bottom of the elastic support member 7, and the ear blocks are connected to the main shaft 1 through screws. In order to facilitate the adjustment of the position of the elastic support member 7, a slide groove is arranged on the surface of the main shaft 1, and the ear blocks are embedded in the slide groove. When adjusted to the corresponding position, the screw is used to fix it.

[0018] like Figure 2 As shown, the support plate 6 is a long arc-shaped plate, the support plate 6 and the rubber strip 4 are perpendicular to each other, and each support plate 6 is connected to 3 to 5 rubber strips 4. The support plate 6 and the rubber strip 4 are in direct contact without a fixing part, and a sticky rubber is provided on the side of the support plate 6 that contacts the rubber strip 4, and the stickiness is used to position the rubber strip 4 to prevent the rubber strip 4 from detaching from the support plate 6.

[0019] like Figure 3 As shown, in order to maintain stability, the elastic support member 7 is provided as two symmetrically arranged arc-shaped plastic rods 8, the two arc-shaped plastic rods 8 are arranged in an arch shape, the two ends of the bottom are connected to the main shaft 1, and the top is connected to the support plate 6. Since the elastic deformation of a single elastic support member 7 will decay due to fatigue, resulting in inability to recover, reducing its supporting force, the arched plastic rod 8 has a stronger supporting force and a longer service life.

[0020] The utility model has a reasonable and ingenious structural design. The support plate can not only ensure the support force of the rubber strip under different tensions, but also ensure the flatness of the rubber strip, and avoid the rubber strip from flipping over during the opening process, thus providing reliable protection for the opening of printed materials. When printing ultra-wide printed materials, the single central support strength of the ultra-long opening rubber roller is insufficient. Multiple support plates can be set for each spindle as needed. When the spindle length is lengthened, support plates of different heights can be distributed on the spindle from the bearing seat to the center of the spindle in sequence to provide the use of ultra-long opening rubber rollers.

[0021] The above is based on the enlightenment of this utility model. Through the above description, relevant staff can make various changes and modifications without deviating from the technical idea of ​​this utility model. The technical scope of this utility model is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
