Description

Technical Field

[0001] The utility model relates to the technical field of paper cutters, in particular to a flattening device for paper cutters. Background Art

[0002] Paper cutters are traditional products used to handle the paper cutting needs in the later stage of printing. They have developed from mechanical paper cutters to tape-controlled paper cutters, and then to microcomputer program control, color display, full image operation guided visual processing and computer-aided cutting external programming and editing of production data cutting systems. When using a paper cutter, a pile of paper is usually cut. After the paper is cut to the required size, the edge of the paper will curl and the edge of the paper pile will shift, which is not conducive to subsequent processing and use. Therefore, a flattening device is needed to flatten the cut paper. The existing flattening device for paper cutters usually places a pile of paper on a platform during use, and then presses the paper down through a pressing plate. Ordinary flattening devices usually have the following problems when pressing paper:

[0003] 1. When placing a thick stack of paper, the top paper is easy to slide and tilt during the flattening process, which causes the entire paper pile to shift during the subsequent flattening process, affecting the flattening quality of the paper pile;

[0004] 2. Different papers have different sizes. Even if a limiting mechanism is added, an ordinary platform cannot limit and fix the paper according to the size of the paper. If the size of the paper is too large or too small, it cannot be fixed well on the table. Utility Model Content

To achieve the above purpose, the utility model provides the following technical solutions: a flattening device for a paper cutter, comprising a bottom plate, the upper surface of the bottom plate is slidably connected to a limiting mechanism, and a flattening mechanism is installed on the top of the limiting mechanism.

[0006] The limiting mechanism includes a support frame, one side of the support frame is slidably connected to an extension frame, the lower surface of the extension frame is connected to a baffle by bolts, one end of the support frame is welded with a first clamping plate, one end of the extension frame is welded with a second clamping plate, the bottom of the first clamping plate is riveted with a rack, one side of the rack is meshed with a gear, the inner wall of the gear is plugged with the output shaft of the motor, the inner wall of the first clamping plate is welded with a spring, and the top of the spring is welded with a storage plate;

[0008] Further preferably, the upper surfaces of the support frame and the extension frame are located on the same horizontal line.

[0009] Further preferably, there are two racks in total, and the two racks are riveted to the first clamping plate and the second clamping plate respectively.

[0010] Further preferably, the gear is rotated by a motor.

[0011] Further preferably, there are a plurality of slide grooves, and the plurality of slide grooves are evenly distributed on the lower surface of the mounting plate.

[0012] Further preferably, the first clamping plate and the second clamping plate are arranged to be a symmetrical structure.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] In the utility model, a slidable first clamping plate and a second clamping plate are added above the bottom plate, and the gear is driven to rotate by a motor. The gear rotates clockwise, driving the racks on both sides to expand outward, and further driving the first clamping plate and the second clamping plate to expand to both sides.

[0024] The flattening mechanism 3 includes a fixed frame 301 welded to the upper surface of the base plate 1, the top of the fixed frame 301 is slidably connected to a lifting cylinder 302, one end of the lifting cylinder 302 is installed with a mounting plate 303, the lower surface of the mounting plate 303 is provided with a slide groove 304, and the inside of the slide groove 304 is slidably connected to a pressing plate 305.

[0025] In this embodiment, Figure 1 and Figure 2 As shown, the upper surfaces of the support frame 201 and the extension frame 202 are located on the same horizontal line; it should be noted that the extension frame 202 can slide along the support frame 201, and the upper surfaces of the two are located on the same horizontal line. When the extension frame 202 slides, it always maintains the same horizontal line as the support frame 201, which can prevent the paper from tilting.

[0026] In this embodiment, Figure 3 As shown, there are two racks 206, and the two racks 206 are riveted to the first clamping plate 204 and the second clamping plate 205 respectively; it should be noted that the two racks 206 are respectively located on both sides of the gear 207, and the two racks 206 drive the first clamping plate 204 and the second clamping plate 205 to move respectively.

[0027] In this embodiment, Figure 3 As shown, the gear 207 rotates through the motor 208. It should be noted that when the motor 208 is started and rotated, the gear 207 is driven to rotate. The gear 207 rotates clockwise, driving the racks 206 on both sides to expand outward, further driving the first clamping plate 204 and the second clamping plate 205 to expand to both sides.

When the motor 208 rotates, the gear 207 is driven to rotate, and the gear 207 rotates counterclockwise to drive the two racks 206 to move closer to the middle, and further drives the first clamping plate 204 and the second clamping plate 205 to move closer to the middle at the same time, clamping and fixing the edge of the paper, and then according to the paper specifications, appropriately increase or decrease the pressure plate 305 to ensure that the edge of the pressure plate 305 is flush with the paper, and the slidable lifting cylinder 302 drives the entire mounting plate 303 and the pressure plate 305 to slide, ensuring that the pressure plate 305 is in the middle of the paper, and the lifting cylinder 302 is started.
