Description

Technical Field

[0001] This application belongs to the field of printing and die-cutting technology, and particularly relates to a paper positioning device for a printing die-cutting machine. Background Technology

[0002] A die-cutting machine is an automatic press, also known as a Thompson machine, designed to process products into desired shapes by pressing down on embedded blades to match the shape of a wooden mold (or template) of the product to be processed. Such die-cutting machines typically include a sheet input unit for supplying wound sheets (or fabric, base film, etc.), a sheet clamping unit for die-cutting the sheet supplied from the sheet input unit, and cutting blades. By pulling the paper output units at intervals, these machines are widely used in the printing industry. With technological advancements, the functions of such printing die-cutting machines have gradually improved, enabling them to better meet the needs of users.

[0003] The cutting position needs to be positioned during the movement of the printed sheet, but the existing die-cutting machine does not perform well in the width direction, so this needs to be improved. Utility Model Content

[0004] The purpose of this application is to address the aforementioned technical problems by providing a paper positioning device for a printing die-cutting machine, which enables the sheet to be positioned in the width direction during movement, thereby improving the stability of the sheet during movement.

[0005] This application provides a paper positioning device for a printing die-cutting machine, comprising:

[0006] Mounting bracket, which is used for mounting and connecting to the die-cutting machine;

[0007] Guide rollers, several of which are provided and mounted on a mounting frame;

[0008] Width control baffles, at least two in number, are movably mounted on the mounting bracket;

[0009] A locking device is used to lock and fix the width control baffle to the mounting bracket;

[0010] The width control baffle is provided with a guide sleeve adapted to the guide roller.

[0011] The guide roller is hinged to the mounting frame and is used to support the sheet material as it passes through. A width control baffle restricts the position of the sheet material in the width direction. The width control baffle is movably positioned on the mounting frame for easy adjustment according to the width of the sheet material. After the position of the width control baffle and the mounting frame is adjusted, they are locked by a locking device to improve the connection stability between the width control baffle and the mounting frame. By setting a guide sleeve between the width control baffle and the guide roller, it is ensured that the guide roller can rotate around its axis and that the width control baffle can move along the axis of the guide roller, allowing relative movement between the width control baffle and the guide roller.

[0012] Furthermore, the locking device includes:

[0013] A locking seat, connected to a width control baffle, is positioned on the upper side of the mounting bracket;

[0014] A locking plate is placed on the lower side of the mounting bracket, and the locking plate is connected to the locking seat by fasteners;

[0015] The mounting bracket is provided with a movable slot, through which the fastener passes.

[0016] The locking seat and locking plate are placed on both sides of the mounting bracket. The mounting bracket is clamped by the locking seat and locking plate with bolts and other fasteners to achieve the locking and fixing of the locking device. When the width control baffle moves, the fasteners can be moved through the movable groove.

[0017] Furthermore, the locking seat and locking plate are provided with anti-slip pads that abut against the mounting bracket.

[0018] The anti-slip pad is made of rubber and other materials. After the locking seat and locking plate clamp the mounting bracket, the anti-slip pad improves the locking stability between the locking seat, locking plate and mounting bracket, and further ensures the positioning stability of the width control baffle.

[0019] Furthermore, the locking seat includes:

[0020] The adjusting screw is connected between the locking seat and the width control baffle, and is threadedly connected to the width control baffle.

[0021] The width control baffle is first moved to the vicinity of the desired position by direct pushing, and then adjusted by rotating the adjusting screw to adjust the width control baffle to the required position, thereby improving the adjustment accuracy of the width control baffle.

[0022] Furthermore, the width control baffle includes:

[0023] A sensor is used to measure the distance between adjacent width control baffles.

[0024] The sensor uses an infrared sensor to detect the distance between the two width control baffles, thereby improving the accuracy of the width control baffles during movement and adjustment.

[0025] Furthermore, the width control baffle also includes:

[0026] A roller is movably mounted on a width control baffle and corresponds to one of the guide rollers.

[0027] The sheet is placed on the guide roller, and the sheet is clamped by the cooperation of the roller and the guide roller to improve the stability of the sheet during movement. The roller is installed on the width control baffle. When the width control baffle moves, the roller can move with the width control baffle to ensure that the roller can act on the side of the sheet.

[0028] Furthermore, the width control baffle also includes:

[0029] The connecting seat is hinged between the roller and the width control baffle;

[0030] The connecting rod is movably connected to all connecting seats.

[0031] The connecting seat is hinged to the roller and the width control baffle. The connecting seat can control the roller to move away from the corresponding guide roller, making it easier for the sheet to pass between the guide roller and the roller. The connecting rod connects all the connecting seats, allowing the roller to be lifted all at once, further improving convenience. The movable connection between the connecting seat and the connecting rod allows the connecting seat to move along the axis of the connecting rod.

[0032] Furthermore, the width control baffle also includes:

[0033] The damper is connected between the width control baffle and the connecting seat;

[0034] The spring is fitted onto the damper.

[0035] By installing a damper and a spring between the width control baffle and the connecting seat, the roller is ensured to exert a force in the direction of the corresponding guide roller, thereby improving the stability of the sheet during movement.

[0036] The beneficial effects of this application are:

[0037] 1. The width control baffle restricts the position of the sheet in the width direction. The width control baffle is movably placed on the mounting frame, which is convenient for adjustment according to the width of the sheet.

[0038] 2. After the width control baffle and the mounting bracket are adjusted in position, they are locked by a locking device to improve the connection stability between the width control baffle and the mounting bracket.

[0039] 3. The sheets are clamped together by the cooperation of rollers and guide rollers to improve the stability of the sheets during movement. Attached Figure Description
