Technical Field

[0001] The utility model relates to the technical field of knife-setting devices, in particular to an infrared knife-setting device for unwinding paper of a paper cutter. Background Art

[0002] With the continuous expansion of the paper products market and the improvement of consumers' requirements for product quality, paper cutters need to meet higher cutting accuracy and efficiency requirements. Traditional paper cutters often rely on manual adjustment of the tool position, which is not only time-consuming and labor-intensive, but also easily affected by human factors in terms of cutting accuracy. Therefore, automated and intelligent paper cutters have gradually become the mainstream in the market.

[0003] Publication number CN210452967U discloses a paper cutter with an improved safety sensing device, comprising a frame, a work platform located at the front of the frame, a cutter mounted on the frame and capable of vertical movement relative to the frame, and a pressure plate mounted on the frame and capable of vertical movement relative to the frame. The front of the work platform is provided with left and right buttons for activating the vertical movement of the cutter, a foot-operated pressure plate switch is located at the bottom front of the frame, and infrared grating sensors are located on the left and right sides of the work platform. The infrared grating sensors are connected in series with the foot-operated pressure plate switch to control the vertical movement of the pressure plate. The paper cutter with the improved safety sensing device of this utility model controls the vertical movement of the pressure plate by connecting the infrared grating sensor and the foot-operated pressure plate switch in series, eliminating the safety hazard of the pressure plate pressing the hand.

[0004] The above-mentioned prior art uses an infrared grating sensor to control the up and down movement of the cutter during use. However, the position of the cutter cannot be adjusted during use, which leads to a limited knife setting range and poor knife setting accuracy, and affects the paper cutting effect of the cutter. The cutting accuracy and cutting quality are poor, so corresponding improvements are needed. Utility Model Content

[0005] The purpose of the present invention is to provide an infrared knife-aligning device for unwinding paper of a paper cutter, so as to solve the problem of inaccurate positioning and poor knife-aligning accuracy of the existing infrared knife-aligning device for unwinding paper of a paper cutter proposed in the above background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: an infrared knife-setting device for unwinding a paper cutter, comprising a support base and a stand, wherein the stand is fixed to the top of the support base, and rubber pads are fixed on both sides of the bottom of the support base;

[0007] Also includes:

[0008] A knife setting adjustment mechanism is provided at the top end of the support seat, a movable plate is connected between the knife setting adjustment mechanisms, and the top end of the movable plate is connected to an electric telescopic rod, the bottom end of the electric telescopic rod is connected to a knife holder, a paper cutter is fixed to the bottom end of the knife holder, fixing mechanisms are provided on both sides of the paper cutter, vertical plates are fixed on both sides of the support seat, and an infrared knife setting assembly is provided on one side of the vertical plate.

[0009] Preferably, the tool adjustment mechanism includes a supporting bar and a driving frame, one side of the driving frame is connected to a driving motor through a support plate, and the output shaft end of the driving motor is connected to a one-way screw, the outer side of the one-way screw is threadedly connected to a threaded block, and the threaded block is slidably connected to the driving frame.

[0010] Preferably, a support column is fixed inside the support bar, and a guide block is sleeved on the outside of the support column, and one side of the guide block and the threaded block are both connected to one side of the movable plate.

[0011] Preferably, two guide rods are fixed on the top blade holder of the paper cutter, and both guide rods pass through the movable plate.

[0012] Preferably, the fixing mechanism includes a fixed block, and the fixed block is arranged on the outside of the paper cutter, an inner cavity is provided in the fixed block, and a compression spring is connected to the inside of the inner cavity, one end of the compression spring is connected to a movable block, and a cardboard limiting column is fixed to the bottom end of the movable block.

[0013] Preferably, guide columns penetrate both sides of the movable block, and the movable block is slidably connected to the guide columns.

[0014] Preferably, the infrared tool setting assembly includes two supporting plates arranged on one side of the vertical plate, and a connecting shaft is connected between the supporting plates, an infrared transmitter is sleeved on the outer side of the connecting shaft, one end of the connecting shaft passes through the supporting plate and is connected to a turntable, and a locking pin is connected to the outer side of the turntable, one end of the locking pin passes through the turntable and extends to the supporting plate, and a receiver and a controller are connected to the outer side of the vertical plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the infrared knife-setting device for paper unwinding of a paper cutter can not only use infrared rays to perform convenient and efficient knife setting to improve the accuracy of paper cutting, but also can synchronously fix the paper during the paper cutting process to improve the stability of paper cutting;

[0016] The infrared transmitter emits an infrared beam to the paper, and the receiver receives the reflected signal. The controller calculates the position and movement speed of the paper based on the received signal, and then controls the drive motor to adjust the position of the paper cutter to ensure the precise alignment of the paper cutter and the paper, so as to ensure the efficiency and accuracy of paper cutting. The electric telescopic rod is also controlled to push the paper cutter downward to cut the paper. When the infrared transmitter is in use, the connecting shaft is rotated by rotating the turntable, which drives the infrared transmitter to rotate. The angle of the infrared transmitter can be adjusted to ensure that the infrared light can accurately illuminate the paper and the measurement is more accurate.

[0017] The driving motor drives the one-way screw to rotate, which is threadedly connected to the threaded block, thereby making the threaded block move back and forth, and driving the movable plate and the paper cutter to move synchronously. The guide block slides along the support column, which serves as a limit guide for the movement of the movable plate, thereby adjusting the position of the paper cutter, so that the paper cutter is accurately aligned with the paper to be cut, ensuring efficient paper cutting.

[0018] The electric telescopic rod pushes the paper cutter to move downward during the paper cutting process, and the fixed block moves downward synchronously, which in turn causes the cardboard limit post to move until the cardboard limit post rests on the paper to limit it. As the paper cutter continues to move downward for cutting, the cardboard limit post and the movable block move into the inner cavity, and the compression spring is compressed, so that the paper is less likely to shift in position during the cutting process, thereby improving the stability of paper cutting.
