Description

Technical Field

[0001] This utility model relates to the technical field of paper processing pretreatment, and more specifically, to a pre-compression device for the conveyor belt of an automatic feeding flatbed machine. Background Technology

[0002] A paper flatbed cutter is an automated cutting device based on CNC technology. Through precise program control of the cutter head (such as a vibrating knife, laser, or mechanical cutter) within a planar coordinate system, it achieves efficient cutting of paper, cardboard, and lightweight sheets. Its core advantage lies in overcoming the limitations of traditional manual cutting—cutting accuracy can reach ±0.05mm, speed exceeds 1 meter / second, and it can handle cardboard up to 80mm thick or multi-layered materials. Combined with a vacuum adsorption table for automatic material fixation, it can complete straight, curved, and even complex irregular-shaped cuts. Widely used in packaging printing, garment pattern making, advertising signage, and cultural and creative design, it significantly improves production efficiency and processing flexibility, becoming a key piece of equipment in modern light industry production.

[0003] Currently, when processing roll paper, the roll is first fixed on a flatbed machine, and then pulled forward by the traction force of an external vacuum adsorption table. However, since the roll paper is originally in a rolled state, it cannot be flattened quickly when pulled onto the vacuum adsorption table and will still curl and warp. This will cause processing errors during paper processing, resulting in an increased scrap rate. Utility Model Content

[0004] The purpose of this utility model is to provide a pre-compression device for the conveyor belt of an automatic feeding flatbed machine. By setting tension springs on both sides of the pre-compression frame, the pre-compression pressure output by the pre-compression roller is kept stable at all times. One end of the tension spring is fixed on the frame and is in a tensioned state, acting on the pre-compression frame to keep the pre-compression pressure of the pre-compression frame stable. This aims to solve the problem in the prior art that when the paper is pulled to the vacuum adsorption table, it cannot be flattened quickly and will still curl and warp, which will cause processing errors during paper processing.

[0005] This utility model is implemented as follows: the pre-compression device of the conveyor belt of the automatic feeding flatbed machine includes a pre-compression frame set on the frame of the automatic feeding flatbed machine. A roll fixing frame is set on one side of the pre-compression frame, and an adsorption platform is set on the other side of the pre-compression frame. An adjustment mechanism is set at the bottom of the pre-compression frame. The adjustment mechanism realizes the adjustment of the center of gravity position of the pre-compression frame, so as to pre-compress the roll of paper output by the roll fixing frame to flatten it.

[0006] Furthermore, the automatic feeding flatbed machine includes a frame located below the adsorption platform and the roll fixing frame. Paper processing equipment is installed on the frame to process the paper on the adsorption platform.

[0007] Furthermore, the upper part of the pre-compression frame is provided with an upper rod, and the middle part of the upper rod is provided with a handle. The handle enables external force to be applied to the pre-compression frame to complete the position adjustment of the pre-compression frame.

[0008] Furthermore, the pre-compression frame is provided with a fixed shaft on one side of the upper rod, and multiple pre-compression rollers are nested on the fixed shaft, with the pre-compression rollers located on the adsorption platform.

[0009] Furthermore, the adjustment mechanism includes a bottom rod disposed at the bottom of the preload frame, and an adjustment pin is fixed on one side of the preload frame of the bottom rod.

[0010] Furthermore, limit grooves are provided on both sides of the lower part of the pre-compression frame, and fixing screws are provided in the limit grooves. The fixing screws pass through the limit grooves and their ends are fixed to the frame.

[0011] Furthermore, a support pin is provided on the frame on one side below the fixing screw, and the support pin supports the preload frame.

[0012] Furthermore, through slots are provided on both sides of the middle part of the pre-compression frame, and tension springs are fastened in the through slots, with one end of the tension springs fixed to the frame.

[0013] Furthermore, a connector is provided on the side of the frame near the adsorption platform, and a connecting screw is provided at the bottom end of the connector to fix the connector to the frame.

[0014] Furthermore, the upper part of the connector is provided with multiple spring mounting slots, one end of the tension spring is fixed in the spring mounting slot, and the tension spring is in a stretched state.

[0015] Compared with the prior art, the pre-compression device for the conveyor belt of the automatic feeding flatbed machine provided by this utility model has the following beneficial effects:

[0016] 1. The adjustment mechanism enables pre-pressing and leveling of paper materials of different thicknesses. Adjusting the position of the fixing screw in the limiting groove achieves different pre-pressure outputs. When the fixing screw is at the lower part of the limiting groove, the pre-pressing frame is in a large tilt state, and the pre-pressing roller outputs a smaller pre-pressure on the adsorption platform, which is used for pre-pressing thin paper materials. When the fixing screw is at the upper part of the limiting groove, the pre-pressing frame is in a small tilt state. At this time, the adjusting nail and the support nail are in contact, and the center of gravity of the pre-pressing frame tilts backward, resulting in a larger pre-pressure on the adsorption platform, which is used for pre-pressing thick paper materials. Furthermore, the adjustment mechanism of the pre-pressing frame only requires pulling the handle with external force to move the position of the fixing screw in the limiting groove, making the operation convenient. It can pre-press and level paper materials of different thicknesses, which is conducive to the precise processing of paper materials in the later stage.

[0017] 2. By setting tension springs on both sides of the pre-pressing frame, the pre-pressure output by the pre-pressing roller is kept stable at all times. One end of the tension spring is fixed on the frame and is in a tensioned state. It acts on the pre-pressing frame to keep the pre-pressure of the pre-pressing frame stable, reduce the vibration of the pre-pressing frame, and ensure that the pre-pressing roller and the adsorption platform are always in contact.

The support pin 13 supports the pre-compression frame 4. By adjusting the position of the fixing screw 11 in the limiting groove 10, different pre-compression pressures can be output.

[0034] In this embodiment, through grooves 14 are provided on both sides of the middle part of the pre-pressure frame 4. Tension springs 15 are fastened in the through grooves 14.

[0035] Reference Figure 7 As shown, when the fixing screw 11 is at the lower part of the limiting groove 10, the pre-pressing frame 4 is in a large tilt state.

By setting tension springs 15 on both sides of the pre-pressing frame 4, the pre-pressure output by the pre-pressing roller 9 is kept stable at all times.
