Description

Technical Field

[0001] This utility model relates to the field of paper cutting equipment technology, and in particular to a paper cutter that is easy to control the cutting depth. Background Technology

[0002] A paper cutter is used to cut paper or books. The paper or book is placed under the cutter blade, which cuts the paper as it moves downwards. In existing paper cutters, the main structure consists of a cutter body mounted between left and right columns, which are mounted on a base plate and fixed to the upper part of a crossbeam. The cutter body or the left and right columns have grooves on them. Driven by a pull rod, the cutter body moves along these grooves, thus completing the cutting operation.

[0003] Existing paper cutters, such as the novel oblique cutting mechanism disclosed in patent number CN 213412075 U, include a platform, two symmetrically arranged columns on the platform, a crossbeam connecting the tops of the two columns, two triangular linkage plates connected to the crossbeams via a rotating shaft, a cutter connecting rod with one end fixed to the rotating shaft, a cutter hinged to the end of the cutter connecting rod away from the rotating shaft, a longitudinal top plate fixed to one end of the cutter, an oblique top rod hinged to the bottom of the longitudinal plate, a drive unit for pushing the oblique top rod to move, a pressure plate connecting rod hinged to the end of the triangular linkage plate away from the rotating shaft, a pressure plate hinged to the end of the pressure plate connecting rod away from the triangular linkage plate, and a transverse connecting rod hinged to the end of the triangular linkage plate away from the rotating shaft and the pressure plate connecting rod. The cutter has two limiting grooves for limiting the cutter connecting rod. This invention allows the cutter to enter the workpiece more smoothly, greatly improving the cutting quality.

[0004] The aforementioned equipment is slow to respond during operation and may even stop. Furthermore, it has low precision in controlling the depth of paper cutting and is not very stable, thus failing to meet actual needs. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a paper cutter that facilitates control over the cutting depth.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a paper cutter that facilitates control of cutting depth, including a frame, a cutter mounted on the frame, a power component that drives the cutter through a linkage component, a rotary encoder, a rotating shaft connected to the rotary encoder, and a stroke response component connected to the rotating shaft. The linkage component drives the rotating shaft to rotate through the stroke response component, so that the encoder drives the power component to operate and control the stroke of the cutter.

[0008] Furthermore, the stroke response component includes a sprocket disposed on the rotating shaft, a chain meshing with the sprocket, and a reset part connected to the chain.

[0009] Furthermore, the chain has a first end and a second end, the first end being connected to the linkage component and the second end being connected to the reset part.

[0010] Furthermore, the reset part is a spring.

[0011] Furthermore, the stroke response component also includes a fixing part for connecting the rotating shaft and the frame. The fixing part includes a first mounting plate, a second mounting plate located on one side of the first mounting plate, a reinforcing plate connecting the first mounting plate and the second mounting plate, and a bearing disposed on the first mounting plate and the second mounting plate for supporting the rotating shaft.

[0012] Furthermore, a positioning plate is vertically connected to the first mounting plate, and a reinforcing plate is provided at the connection between the positioning plate and the first mounting plate.

[0013] Furthermore, the stroke response component also includes a connecting part for connecting the rotary encoder and the first mounting plate. The connecting part includes a first horizontal plate symmetrically disposed at the bottom of the rotary encoder, a second horizontal plate disposed on the first mounting plate, and a vertical plate connecting the first horizontal plate and the second horizontal plate.

[0014] The paper cutter proposed in this utility model is easy to control in terms of cutting depth, and its advantages are as follows:

[0015] This invention sets up a rotary encoder, a rotating shaft, and a stroke response component. By using the linkage component and the stroke response component to drive the rotating shaft to rotate, the rotary encoder drives the power component to operate and control the stroke of the cutter, thereby achieving precise limiting of the cutter and facilitating control over the depth of paper cutting.

It also includes a rotary encoder 5, a rotating shaft 6 connected to the rotary encoder 5, and a stroke response component 7 connected to the rotating shaft 6. The linkage component 3 drives the rotating shaft 6 to rotate via the stroke response component 7, so that the encoder 5 drives the power component 4 to move and control the stroke of the cutter 2. In this embodiment, the rotary encoder 5 is connected to a controller (not shown), and the controller controls the operation of the power component 4 according to the signal from the rotary encoder 5.

[0022] This invention sets up a rotary encoder 5, a rotating shaft 6, and a stroke response component 7.

At this time, the rotary encoder 5 generates a signal, and the controller uses the signal to control the action of the power component 4 to achieve precise positioning of the cutter 2, which facilitates the control of the depth of paper cutting.

[0025] In an optional embodiment of this utility model, the reset part 703 is a spring. In this embodiment, one end of the spring is connected to the second end 705 of the chain 702, and the other end is connected to the top of the frame 1.

In this embodiment, by setting the bearing 7064 to support the rotating shaft 6, the smooth rotation of the rotating shaft 6 is ensured, thereby improving the stability of the rotary encoder 5 during operation and ensuring precise positioning of the cutter 2.

[0027] In an optional embodiment of this utility model, a positioning plate 7065 is vertically connected to a first mounting plate 7061, and a reinforcing plate 7066 is provided at the connection between the positioning plate 7065 and the first mounting plate 7061. In this embodiment, the positioning plate 7065 is fixed to the frame 1 by bolts. At the same time, the reinforcing plate 7066 is used to improve the connection strength between the positioning plate 7065 and the first mounting plate 7061, ensuring the smooth operation of the stroke response component 7.

[0028] In an optional embodiment of this utility model, the stroke response component 7 further includes a connecting part 707 for connecting the rotary encoder 5 and the first mounting plate 7061. The connecting part 707 includes a first horizontal plate 7071 symmetrically disposed at the bottom of the rotary encoder 5, a second horizontal plate 7072 disposed on the first mounting plate 7061, and a vertical plate 7073 connecting the first horizontal plate 7071 and the second horizontal plate 7072. In this embodiment, the second horizontal plate 7072 is fixed to the first mounting plate 7061 by bolts or welding. By setting the connecting part 707 to connect the rotary encoder 5 and the first mounting plate 7061, the stability of the rotary encoder 5 during operation is further improved.
