Description

Technical Field

[0001] This utility model relates to the field of digital display paper cutter technology, and in particular to a cutting mechanism and a digital display paper cutter. Background Technology

[0002] A digital display paper cutter is a professional cutting device that uses digital display and control. It is mainly used for the precise cutting of materials such as paper, cardboard, photos, leather, and plastic film. Compared with traditional mechanical paper cutters, digital display paper cutters have the characteristics of high precision, easy operation, and high efficiency.

[0003] A search revealed a patent with authorization announcement number CN205901780U. This technical solution has the following problems:

[0004] Currently, most digital display paper cutters require users to reach under the blade to pick up or put down the paper during the cutting process, which poses a significant safety hazard. This can easily lead to accidental activation of the blade operation switch when picking up or putting down the paper, greatly reducing safety.

[0005] To address the aforementioned problems, this utility model document proposes a cutting mechanism and a digital display paper cutter. Utility Model Content

[0006] This utility model provides a cutting mechanism and a digital display paper cutter, which solves the problem that in the prior art, most digital display paper cutters require users to put their hands under the blade to pick up and put down the paper during the cutting process, which poses a great safety hazard and makes it easy to accidentally touch the blade operation switch when picking up and putting down the paper, greatly reducing safety.

[0007] This utility model provides the following technical solution:

[0008] A digital display paper cutter, comprising:

[0009] The digital display paper cutter body has a top block welded to its top side, and a second limiting block for limiting the paper is fixedly installed between the two sides of the inner wall of the top block. The top block has a moving groove inside.

[0010] The paper-cutting process includes a support and movement mechanism, which is installed on the main body of the digital display paper cutter to support and move the paper to be cut.

[0011] The pressing mechanism is located on the top block and is used to press and fix the paper to be cut.

[0012] In one possible design, the supporting mechanism includes a chute, a placement plate, slide bars, slide rails, and a locking frame. The chute is located on the top of the digital display paper cutter body. The placement plate is slidably connected to the inside of the chute for supporting and moving the paper to be cut. Two slide bars are welded to both sides of the placement plate. Two slide rails are located on the inner walls of both sides of the chute for limiting the sliding of the slide bars. The locking frame is welded to one side of the placement plate.

[0013] In one possible design, a fixed frame is welded to one side of the digital display paper cutter body, a telescopic rod is welded to the bottom inner wall of the fixed frame, a spring is sleeved on the outer wall of the telescopic rod, a push-pull plate is welded to the top of the telescopic rod, and a locking block is welded to the top side of the push-pull plate for insertion and locking into the corresponding locking frame.

[0014] In one possible design, the pressing mechanism includes a mounting slot, an electric push rod, a drive plate, a drive rod, and a pressing block. The mounting slot is located on the top of the top block. The electric push rod is fixedly installed inside the mounting slot. The output end of the electric push rod passes through the bottom side of the inner wall of the mounting slot and extends into the interior of the moving slot. The drive plate is fixedly mounted on the output end of the electric push rod. Both drive rods are welded to the bottom side of the drive plate. The pressing block is welded to the bottom ends of the two drive rods and is used to press and fix the paper to be cut.

[0015] A cutting mechanism for mounting on a digital display paper cutter includes a mounting cavity located on the top side of a top block. A motor is fixedly mounted inside the mounting cavity. The output end of the motor passes through the bottom side of the inner wall of the mounting cavity and extends into the interior of a moving slot. A lead screw is fixedly mounted on the output end of the motor via a coupling. The bottom end of the lead screw is rotatably connected to the top side of the digital display paper cutter body.

[0016] In one possible design, the outer wall of the lead screw is threaded with a threaded block, and a cutting blade for cutting paper is fixedly mounted on one side of the threaded block.

[0017] In one possible design, a first limiting block is fixedly installed on the side of the cutting blade away from the threaded block, and a limiting rod is welded between the top side and the bottom side of the inner wall of the moving groove. The first limiting block has a sliding hole that is slidably connected to the outer wall of the limiting rod.

[0018] In this application, during use, the paper to be cut is first placed on the placement plate, and then the push-pull plate is pressed down. The push-pull plate causes the telescopic rod to retract, and at the same time the spring is compressed. The locking block on the top side of the push-pull plate moves downward to release the locking effect of the placement plate. Then, the placement plate is pushed, and the sliders on both sides of the placement plate slide in the slide rails on the inner walls of the slide groove, so that the placement plate can move stably in the slide groove. This can move the paper to the appropriate position at the bottom of the corresponding cutting blade, which is convenient for moving the paper from under the cutting blade to a remote distance when picking up or putting down the paper, so as to achieve safe paper handling and avoid the phenomenon of accidentally touching the blade operation switch when picking up or putting down the paper, which greatly improves safety. When the placement plate is moved to the desired position, the push-pull plate is released. Under the elastic force of the spring, the locking block will insert into the locking frame on one side of the placement plate to lock the placement plate and prevent the placement plate from moving during the paper cutting process, thus improving stability.

[0019] After the paper is moved to the appropriate cutting position, the second limiting block can adhere and limit one side of the paper, further improving flatness. Then, the electric push rod is activated, and its output end extends downward, driving the drive plate downward. The two drive rods on the bottom side of the drive plate move downward accordingly, thereby driving the pressing block downward. After the pressing block contacts the paper, it presses and fixes the paper, preventing displacement during cutting and improving stability. Subsequently, the motor is activated, and its output end drives the lead screw to rotate through the coupling. Since the threaded block is threadedly connected to the lead screw, and the sliding hole inside the first limiting block slides on the outer wall of the limiting rod, it facilitates the limiting effect on the threaded block, allowing it to move only along the axial direction of the lead screw. This drives the cutting blade to move up and down. When the cutting blade moves to the appropriate position, it contacts the pressed and fixed paper. As the cutting blade continues to move, it facilitates the cutting operation of the paper, improving applicability. During the cutting process, the digital display paper cutter body can display relevant cutting parameters, allowing operators to accurately control the cutting process.

[0020] In this utility model, the cutting mechanism and digital display paper cutter can move the paper to a suitable position at the bottom of the corresponding cutting blade through the lifting mechanism, so as to move the paper from under the cutting blade to a remote distance when picking up and putting down the paper, thereby achieving safe paper handling.

[0021] In this utility model, the cutting mechanism and digital display paper cutter can drive the pressing block to move downward through the pressing mechanism, and press and fix the paper to prevent the paper from shifting during the cutting process, thereby improving the stability during cutting.

[0022] In this invention, during the paper cutting process, the paper can be moved to a suitable position at the bottom of the corresponding cutting blade. This makes it easier to move the paper from under the cutting blade to a remote distance when picking up or putting down the paper, thus ensuring safe paper handling and avoiding accidental activation of the blade operation switch when picking up or putting down the paper, greatly improving safety.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0031] The problem in the existing digital display paper cutter field is that most digital display paper cutters require users to reach under the blade to pick up and put down the paper during the cutting process, which poses a great safety hazard. This can easily lead to accidental activation of the blade operation switch when picking up and putting down the paper, greatly reducing safety. To address this problem, this solution designs a cutting mechanism.

[0032] Please refer to Figures 1-5 A digital display paper cutter, comprising:

[0033] The digital display paper cutter body 1 has a top block 2 welded to its top side. A first limiting block 26 for limiting the paper is fixedly installed between the two sides of the inner wall of the top block 2. A moving groove 3 is opened inside the top block 2. The first limiting block 26 can be used to fit and limit one side of the paper, further improving the flatness.

[0034] The paper-cutting process includes a support mechanism mounted on the digital display paper cutter body 1. This mechanism supports and moves the paper to be cut. The support mechanism comprises a slide 16, a placement plate 17, slide bars 18, slide rails 19, and a locking frame 20. The slide 16 is located at the top of the digital display paper cutter body 1. The placement plate 17 is slidably connected to the inside of the slide 16 for supporting and moving the paper to be cut. Two slide bars 18 are welded to both sides of the placement plate 17, and two slide rails 19 are located on both sides of the slide 16. The wall is used for limiting the sliding of the slider 18. The locking frame 20 is welded to one side of the placement plate 17. The paper to be cut is placed on the placement plate 17. The placement plate 17 is pushed, and the sliders 18 on both sides of the placement plate 17 slide in the slide rails 19 on both sides of the slide groove 16, so that the placement plate 17 can move stably in the slide groove 16. This can drive the paper to the appropriate position at the bottom of the corresponding cutting blade 8, so that when picking up and putting down the paper, the paper can be moved from under the cutting blade 8 to a remote distance to achieve safe paper handling.

[0035] A fixed frame 21 is welded to one side of the digital display paper cutter body 1. A telescopic rod 22 is welded to the bottom inner wall of the fixed frame 21. A spring 23 is sleeved on the outer wall of the telescopic rod 22. A push-pull plate 24 is welded to the top of the telescopic rod 22. A locking block 25 is welded to the top side of the push-pull plate 24 for insertion and locking into the corresponding locking frame 20. When the push-pull plate 24 is pressed down, the push-pull plate 24 drives the telescopic rod 22 to retract. At the same time, the spring 23 is compressed, and the locking block 25 on the top side of the push-pull plate 24 moves downward to release the locking effect of the placement plate 17. When the placement plate 17 moves to the desired position, the push-pull plate 24 is released. Under the elastic force of the spring 23, the locking block 25 will insert into the locking frame 20 on one side of the placement plate 17 to lock the placement plate 17, preventing the placement plate 17 from moving during the paper cutting process and improving stability.

[0036] The pressing mechanism, mounted on the top block 2, is used to press and fix the paper to be cut. The pressing mechanism includes a mounting groove 11, an electric push rod 12, a drive plate 13, drive rods 14, and a pressing block 15. The mounting groove 11 is located at the top of the top block 2. The electric push rod 12 is fixedly installed inside the mounting groove 11, with its output end penetrating the bottom side of the inner wall of the mounting groove 11 and extending into the interior of the moving groove 3. The drive plate 13 is fixedly mounted on the output end of the electric push rod 12. Two drive rods 14 are welded to the bottom side of the drive plate 13, and the pressing block 15 is welded to the bottom ends of the two drive rods 14. It is used to press and fix the paper to be cut. When the electric push rod 12 is activated, its output end extends downward, causing the drive plate 13 to move downward. The two drive rods 14 on the bottom side of the drive plate 13 move downward accordingly, further causing the pressing block 15 to move downward. After the pressing block 15 contacts the paper, it presses and fixes the paper, preventing displacement during cutting and improving stability.

[0037] This application can be used in the field of digital display paper cutters, or in other fields applicable to this application. Example

[0038] refer to Figures 1-5 An improvement based on Embodiment 1: a cutting mechanism applied to the field of digital display paper cutters;

[0039] For installation on a digital display paper cutter, it includes a mounting cavity 4, which is located on the top side of the top block 2. A motor 5 is fixedly installed inside the mounting cavity 4. The output end of the motor 5 passes through the bottom side of the inner wall of the mounting cavity 4 and extends into the interior of the moving groove 3. A lead screw 6 is fixedly installed on the output end of the motor 5 via a coupling. The bottom end of the lead screw 6 is rotatably connected to the top side of the digital display paper cutter body 1. A threaded block 7 is threadedly connected to the outer wall of the lead screw 6. A cutting blade 8 for cutting paper is fixedly installed on one side of the threaded block 7. A first limiting block 9 is fixedly installed on the side of the cutting blade 8 away from the threaded block 7. A limiting rod 10 is welded between the top and bottom sides of the inner wall of the moving groove 3. A sliding hole is opened inside the first limiting block 9, which is slidably connected to the outer wall of the limiting rod 10.

[0040] The output end of motor 5 drives lead screw 6 to rotate through coupling. Since threaded block 7 is threadedly connected to lead screw 6, and the sliding hole inside first limit block 9 slides on the outer wall of limit rod 10, it is convenient to limit threaded block 7, so that threaded block 7 can only move along the axial direction of lead screw 6, thereby driving cutting blade 8 to move up and down. When cutting blade 8 moves to the appropriate position, it contacts the paper that has been pressed and fixed. As cutting blade 8 continues to move, it is beneficial to complete the paper cutting operation and improve applicability.

[0041] However, as is well known to those skilled in the art, the working principles and wiring methods of the digital display paper cutter body 1, motor 5 and electric push rod 12 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0042] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations, but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0043] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
