Description

Technical Field

[0001] This utility model relates to the field of paper cutter technology, and in particular to an adaptive pressure regulating clamping mechanism for a paper cutter. Background Technology

[0002] Paper cutters are traditional products used to handle paper cutting needs in the later stages of printing. They have evolved from mechanical paper cutters to magnetic tape-controlled paper cutters, and further to microcomputer-controlled, color-display, fully image-guided visual processing, and computer-aided cutting systems with external programming and editing of production data, resulting in shorter production preparation time and higher cutting accuracy.

[0003] Currently, existing paper cutters require workers to manually stack the paper neatly in the cutter using a pusher plate to ensure clean cuts during subsequent cutting. However, existing paper cutters lack a cutting protection mechanism. When workers work for a long time, they may become tired or distracted and leave their hands in the cutter, which can easily lead to safety hazards.

[0004] Therefore, this application proposes an adaptive pressure regulating clamping mechanism for a paper cutter. Utility Model Content

[0005] This utility model discloses an adaptive pressure regulating clamping mechanism for a paper cutter, which aims to solve the technical problem that existing paper cutters lack a cutting protection mechanism.

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

[0007] An adaptive pressure regulating clamping mechanism for a paper cutter includes a platform and a mounting frame. A cutting position adjusting mechanism is provided between the mounting frame and the platform. A cutting groove is provided on the upper surface of the platform. A paper body is provided inside the cutting groove. A clamping mechanism and a cutting mechanism are respectively provided inside and on the front of the mounting frame.

[0008] The cutting mechanism includes a connecting plate fixedly installed on the front of the mounting frame. A hydraulic press is embedded on the upper surface of the connecting plate. The telescopic end of the hydraulic press extends to the lower surface of the connecting plate and is fixedly installed with a cutting blade. A cutting protection mechanism is provided on the front of the connecting plate.

[0009] The cutting protection mechanism includes a rotating rod rotatably connected to the front of the connecting plate. A transmission gear and a scraper are fixedly installed on the surface and front end of the rotating rod, respectively. A transmission rack that meshes with the transmission gear is fixedly connected to the front of the cutting blade. A controller is provided on the right side surface of the platform.

[0010] In a preferred embodiment, the clamping mechanism includes a first motor fixedly mounted on the upper surface of the mounting frame. The output shaft of the first motor extends into the interior of the mounting frame and is fixedly connected to a threaded rod. A stop is threadedly connected to the surface of the threaded rod. Two symmetrical sliding grooves are provided on the lower surface of the stop. T-shaped rods are slidably connected inside the sliding grooves. Pressure plates are fixedly connected to the lower ends of the two T-shaped rods.

[0011] In a preferred embodiment, a pressure sensor is mounted on the lower surface of the abutment, and the detection end of the pressure sensor overlaps with the upper surface of the pressure plate.

[0012] By setting up a pressure sensor, the pressure generated when the pressure plate presses against the paper body can be monitored, thus preventing damage to the paper body due to excessive pressure.

[0013] In a preferred embodiment, a spring is fixedly connected to the upper end of the T-shaped rod, and the upper end of the spring is fixedly connected to the inner top wall of the sliding groove.

[0014] By using a spring, the T-shaped rod can drive the pressure plate to press against the paper body, achieving a pre-fixing effect.

[0015] In a preferred embodiment, guide sliders are provided on both sides of the abutment, and guide grooves for the guide sliders to slide are provided on both sides of the inner wall of the mounting frame.

[0016] By setting a guide slider, the pressure plate can be moved up and down in a directional manner by the rotation of the threaded rod under the guidance of the guide slider.

[0017] In a preferred embodiment, the cutting position adjustment mechanism includes two symmetrical adjustment slots formed on the upper surface of the platform. A guide slide rod is fixedly installed on the inner front wall and inner rear wall of the left adjustment slot. A reciprocating screw is rotatably connected to the inner front wall and inner rear wall of the right adjustment slot. A second motor is fixedly installed on the back of the platform. The output shaft of the second motor extends into the interior of the right adjustment slot and is fixedly connected to the rear end of the reciprocating screw. A threaded block is threadedly connected to the surface of the reciprocating screw. A sliding block is slidably connected to the surface of the guide slide rod. The upper surfaces of the sliding block and the threaded block are fixedly connected to the lower surface of the mounting frame.

[0018] By using a second motor and a reciprocating lead screw, the cutting position of the cutting blade can be adjusted via the mounting frame.

[0019] As can be seen from the above, the adaptive pressure regulating clamping mechanism for a paper cutter provided by this utility model has the following technical effects.

[0020] Firstly, during cutting, the operation of the hydraulic press drives the cutting blade to descend until the cutting operation is completed. During this period, the descent of the cutting blade drives the transmission gear to rotate through the transmission rack. The rotation of the transmission gear drives the scraper to rotate within the cutting groove. The rotation of the scraper can push away the hands of personnel stuck in the cutting groove, thereby achieving the effect of cutting protection and improving the safety of the cutting machine.

[0021] Secondly, after the paper body is placed in the cutting groove of the platform, the operation of the first motor drives the threaded rod to rotate. Under the guidance of the guide slider, the seat, through the rotation of the threaded rod, drives the pressure plate to press against the paper body until the pressure plate contacts the pressure sensor on the lower surface of the seat. When the pressure of the pressure plate on the paper body reaches a certain value, the pressure sensor controls the first motor to stop through the controller. This allows the device to adjust the pressing force of the pressure plate according to the different thicknesses of the stacked paper bodies, avoiding damage to the paper body due to excessive pressure.

A transmission rack 10 that meshes with the transmission gear 8 is fixedly connected to the front of the cutting blade 6. A controller 11 is provided on the right side surface of the platform 1.

[0033] Reference Figure 4 and Figure 5 In a preferred embodiment, the clamping mechanism includes a first motor 12 fixedly mounted on the upper surface of the mounting frame 2.

A stop 14 is threadedly connected to the surface of the threaded rod 13. Two symmetrical sliding grooves are provided on the lower surface of the stop 14. T-shaped rods 15 are slidably connected inside the sliding grooves. Pressure plates 16 are fixedly connected to the lower ends of the two T-shaped rods 15.

[0034] A pressure sensor 17 is installed on the lower surface of the seat 14, and the detection end of the pressure sensor 17 overlaps with the upper surface of the pressure plate 16. By setting the pressure sensor 17, the pressure generated when the pressure plate 16 presses against the paper body 3 can be monitored, so as to avoid damage to the paper body 3 due to excessive pressure.

[0035] A spring 18 is fixedly connected to the upper end of the T-shaped rod 15. The upper end of the spring 18 is fixedly connected to the inner top wall of the sliding groove. Through the setting of the spring 18, the pressure plate 16 can be driven by the T-shaped rod 15 to press against the paper body 3, so as to achieve the effect of pre-fixation.

[0036] Guide sliders 19 are provided on both sides of the abutment 14, and guide grooves for sliding of guide sliders 19 are provided on both sides of the inner wall of the mounting frame 2. Under the guidance of guide sliders 19, the abutment 14 can drive the pressure plate 16 to move up and down in a directional manner through the rotation of threaded rod 13.

[0037] Reference Figure 5 and Figure 6 In a preferred embodiment, the cutting position adjustment mechanism includes two symmetrical adjustment slots on the upper surface of the platform 1. A guide slide rod 20 is fixedly installed on the inner front wall and inner rear wall of the left adjustment slot. A reciprocating screw 21 is rotatably connected to the inner front wall and inner rear wall of the right adjustment slot. A second motor 22 is fixedly installed on the back of the platform 1.

[0039] Working principle: After the paper body 3 is placed in the cutting groove of the platform 1, the operation of the first motor 12 drives the threaded rod 13 to rotate. Under the guidance of the guide slider 19, the abutment 14, through the rotation of the threaded rod 13, drives the pressure plate 16 to press against the paper body 3 via the T-shaped rod 15 until the pressure plate 16 contacts the pressure sensor 17 on the lower surface of the abutment 14. When the pressure of the pressure plate 16 on the paper body 3 reaches a certain value, the pressure sensor 17 controls the first motor 12 to stop through the controller 11. This allows the device to adjust the pressing force of the pressure plate 16 according to the different thicknesses of the stacked paper bodies 3, avoiding damage to the paper body 3 due to excessive pressure. During cutting, hydraulic pressure... The operation of machine 5 drives the cutting blade 6 to descend until the cutting operation is completed. During this period, the descent of the cutting blade 6 drives the transmission gear 8 to rotate through the transmission rack 10. The rotation of the transmission gear 8 drives the scraper 9 to rotate in the cutting groove. The rotation of the scraper 9 can push away the hands of personnel stuck in the cutting groove, thereby achieving the effect of cutting protection. When it is necessary to adjust the cutting position of the cutting blade 6, the operation of the second motor 22 drives the reciprocating screw 21 to rotate. Under the guidance of the moving block and the guide slide 20, the threaded block 23 can drive the mounting frame 2 to move directionally above the platform 1 through the rotation of the reciprocating screw 21 until the cutting blade 6 moves to the required cutting position, and then its cutting position can be adjusted.
