Description

Technical Field

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

[0002] A paper cutter is a paper processing equipment, also known as a single-sided knife. It is a device used to handle the paper cutting needs in the later stage of printing. It has developed from mechanical paper cutters to tape-controlled paper cutters, and then to microcomputer program control, color display, full image operation guidance visualization processing and computer-aided cutting external programming and editing of production data cutting systems. Paper cutters have been able to achieve shorter production preparation time, higher cutting accuracy, lower labor intensity and safer operation. Paper cutters are divided into two categories: fling knife paper cutters (which are divided into single knife and double knife) and flat knife paper cutters. The fling knife paper cutter includes a longitudinal cutting mechanism consisting of an upper knife and a lower knife, and a cross-cutting mechanism consisting of a rotary long knife and a fixed bottom knife. It can cut multiple paper rolls at the same time. The flat knife paper cutter has a liftable gate knife on the platform, which is used to cut flat paper into specified sizes. It is suitable for cutting labels, carbon paper, hardcover books, etc. Regarding the blade adjustment mechanism, it plays a vital role in the paper cutter. Adjusting the blade is mainly to ensure the accuracy and efficiency of cutting, as well as to improve In order to ensure the quality of high-cut products, in actual operation, blade adjustment usually involves the adjustment of blade gap, angle and position. These adjustments can be achieved by rotating the adjusting screw, moving the blade seat or adjusting the blade fixing screw. During the adjustment process, it is necessary to comprehensively consider factors such as cutting requirements, material properties and equipment structure to obtain the best cutting effect. In summary, the blade adjustment mechanism is an indispensable and important part of the paper cutter. It is of great significance to ensure cutting accuracy, improve cutting efficiency, and protect equipment and safety. The common paper cutters on the market generally lack the function of adjusting the cutting angle of the tool, which greatly limits its ability to cut paper at 45° angles and other angles, thereby affecting its practicality and flexibility. In addition, when dealing with thinner cutting operations, the reciprocating motion efficiency of the cutter head of these paper cutters is not ideal, resulting in low cutting efficiency and difficulty in meeting the needs of efficient operations. For example, the "Utility Model CN22 Eccentric Turning Block 2073U A blade adjustment device for a three-sided knife paper cutter. This utility model uses the mutual cooperation between the connecting ear, connecting shaft, motor, coupling, transmission gear and driven gear to enable the knife holder to flip at the bottom of the movable knife seat when the motor is controlled to rotate forward and reverse, thereby achieving the adjustment of the knife angle, so as to facilitate multi-angle cutting of paper and improve practicality. In response to the above problems, there may be technical means to solve them in the existing technology, but this case aims to provide an alternative or replacement technical solution. Utility Model Content

[0003] To achieve the above objectives, the present invention is implemented through the following technical solutions: a blade adjustment mechanism for a paper cutter, comprising: a mechanism housing, a primary connecting block, and a pair of mechanism mounting flanges, wherein the pair of mechanism mounting flanges are respectively mounted on the mechanism housing, a cutter head mounting angle adjustment assembly is mounted on the primary connecting block, and a high-efficiency reciprocating cutting drive structure is mounted on the mechanism housing;

[0004] The high-efficiency reciprocating cutting drive structure includes: a reciprocating power motor, an eccentric rotating block, an eccentric bearing, a primary transmission rotating shaft, a reciprocating traction block, a secondary transmission rotating shaft, a guide limit slide rail and a connecting slide block;

[0005] The reciprocating power motor is installed in the mechanism housing, the eccentric rotating block is connected to the reciprocating power motor, the eccentric rotating block is installed on the mechanism housing through a bearing, the eccentric bearing is installed on the eccentric rotating block, the primary conduction rotating shaft is respectively inserted into the eccentric rotating block and the eccentric bearing, the reciprocating traction block is respectively sleeved on the primary conduction rotating shaft and the secondary conduction rotating shaft, the guide limiting slide rail is installed on the mechanism housing, the connecting slider is installed on the guide limiting slide rail, and the secondary conduction rotating shaft is connected to the connecting slider;

[0006] It should be noted that, in the above, the entire adjustment mechanism is installed in the paper cutter frame through a pair of mechanism mounting flanges and flange connection holes provided thereon. When thinner and more frequent cutting tasks are required, the reciprocating power motor in the driving mechanism housing is operated, thereby causing the eccentric rotating block to rotate. Because the eccentric bearing is not at the rotation center of the eccentric rotating block, the primary conduction shaft is pulled and rotated by relying on the eccentric bearing, thereby pulling the reciprocating traction block to move. The pulled reciprocating traction block drives the secondary conduction shaft to move, thereby pulling the connecting slider to move back and forth up and down relying on the guide limit slide rail. In summary, it can be concluded that when the reciprocating power motor is running, the primary connecting block is driven and performs reciprocating high-frequency vertical motion, thereby driving the paper cutter body to perform reciprocating high-speed cutting motion.

[0007] Preferably, the cutter head angle adjustment assembly comprises: an angle adjustment power housing, a deflection adjustment motor, a deflection rotation shaft, a pair of cutter body mounting bolts, a cutter body clamping block and a paper cutting cutter body;

[0008] The angle adjustment power housing is mounted on the primary connecting block, the deflection adjustment motor is mounted in the angle adjustment power housing, and the deflection adjustment motor is connected to the deflection rotation shaft, the knife body clamping block is fixedly sleeved on the deflection rotation shaft, a pair of knife body mounting bolts are respectively inserted into the knife body clamping block and the paper cutter body, and the paper cutter body is inserted into the knife body clamping block;

[0009] It should be noted that, in the above, when the paper cutter body needs to be adjusted, the deflection adjustment motor in the angle adjustment power shell is driven to operate, thereby causing the deflection rotating shaft to rotate, and because the deflection rotating shaft and the knife body clamping block are fixedly connected, when the deflection rotating shaft is deflected, the knife body clamping block will be deflected cooperatively, thereby adjusting the inclination angle of the paper cutter body. When the paper cutter body needs to be replaced, it is only necessary to remove a pair of knife body mounting bolts, so that the paper cutter body can be easily removed from the knife body clamping block. After installation, the pair of knife body mounting bolts can be reset. The blade positioning groove provided on the knife body clamping block can make the connection between the paper cutter body and the knife body clamping block more firm and tight, and the replacement-related dust cover provided on the angle adjustment power shell can facilitate the maintenance and maintenance of the deflection adjustment motor, and can play a dust-proof role in normal times.

[0010] Preferably, a maintenance access port is provided on the mechanism housing;

[0011] Preferably, the mechanism placement flange is provided with a flange connection hole;
