Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, and in particular to a printing cutting machine with safety protection. Background Technology

[0002] Before printing, designers create layouts based on the size and quantity of the printed materials. This requires pre-cutting the paper to ensure each printed item can be accurately separated after layout. After printing, each sheet may contain multiple printed items, which need to be cut to separate them into individual finished products. In short, pre- and post-printing cutting processes are crucial for ensuring print quality and dimensional accuracy. Printing cutting machines are used in this process, as shown below.

[0003] A search revealed a patent with authorization announcement number CN221314291U, which discloses a printing paper cutting machine. The machine includes a base frame with a protective structure and a leveling structure. The protective structure includes electric push rods, guard plates, and through holes. Multiple sets of electric push rods are distributed and installed on the inner wall of the base frame, two sets of guard plates are distributed and installed on the top of the electric push rods, and two sets of through holes are formed at the top of the base frame. In use, the printing paper to be cut is placed on the top of the base frame. The electric push rods are then activated, causing the guard plates to rise and pass through the through holes. Together with the two sets of push plates in the leveling structure, the printing paper to be cut is surrounded. The guard plates, on the one hand, work with the movable push plates to level and align the printing paper; on the other hand, they surround the printing paper as a protective measure, preventing accidental injury to workers during cutting, eliminating potential safety hazards, and improving the safety of the cutting machine.

[0004] However, the above-mentioned cutting machine still has the following areas for improvement. For example, when workers put in or take out paper during the cutting process, their hands will inevitably need to reach under the cutter to adjust the paper's position or take it out. If the cutter is accidentally activated at this time, it can easily cause serious injury to the worker's hands. Therefore, its safety is generally poor, and its safety protection needs to be improved, and its practicality needs to be enhanced. Utility Model Content

[0005] This utility model discloses a printing and cutting machine with safety protection. It features a safety loading and unloading mechanism, allowing the printing paper to be placed on the support base during cutting. The paper's sides are aligned with the inner corners of the limiting plate. Two second sliding grooves are then used to adjust the position of the abutment seat, ensuring it is firmly against the printing paper. Rotating the abutment knob until it is firmly against the support base provides proper limiting and fixing of the printing paper, facilitating neat cutting later. After the paper is loaded, adjusted, and fixed, the motor is started, driving the lead screw to rotate. The lead screw rotation moves the slider, coordinating with the two second sliding grooves... A chute moves the carrier and printing paper horizontally until the printing paper is positioned appropriately below the cutting mechanism. Cutting of the printing paper then begins. After cutting, the motor restarts, resetting the carrier and moving the printing paper away from the cutting mechanism. The contact knob is then released to adjust the contact position, and the unloading process begins. During this process, since the worker is away from the cutting mechanism when placing and removing the paper, accidental hand injuries due to accidental activation of the cutting mechanism are effectively prevented, significantly improving safety. In summary, this solves the problems described in the background technology.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model discloses a printing and cutting machine with safety protection, including a worktable, the bottom of which is provided with multiple support legs, the top of which has two first sliding grooves opened horizontally, and the top of which has a through movable groove between the two first sliding grooves. A mounting frame is fixedly installed on the top of the worktable, and the mounting frame is U-shaped.

[0008] A safe loading and unloading mechanism includes a support base, a lead screw, and a motor. The bottom of the support base is slidably connected to two first sliding grooves via multiple sliding connectors, and the support base is located away from the mounting frame. An L-shaped limiting plate is fixedly installed on the top of the support base. Printing paper is stacked on the top of the support base, with two sides of the printing paper respectively abutting the inner corners of the limiting plate. The lead screw is rotatably mounted on the bottom of the worktable via two bearing seats. A slider is screwed to the outside of the lead screw, and the top of the slider passes through a movable groove and is fixedly connected to the bottom of the support base. The motor is fixedly mounted on the bottom of the worktable via mounting parts, and the output end of the motor is connected to the shaft end of the lead screw.

[0009] A cutting mechanism, which is located inside the mounting frame;

[0010] A dust collection mechanism is located on the top and one side of the mounting frame.

[0011] Furthermore, the top of the support seat has two second sliding grooves longitudinally provided, and an L-shaped abutment seat is slidably installed in the second sliding groove. One side of the abutment seat is attached to one side of the printing paper, and an abutment knob is screwed onto the abutment seat. The bottom end of the abutment knob abuts against the top of the support seat.

[0012] Furthermore, the cutting mechanism includes a fixed base, a cylinder, a lifting base, and a cutter. The fixed base is fixedly installed inside the mounting frame. There are two cylinders, both of which are fixedly installed through the fixed base. The top of the lifting base is fixedly connected to the telescopic ends of the two cylinders. The cutter is fixedly installed at the bottom of the lifting base.

[0013] Furthermore, the size of the lifting seat is smaller than the internal size of the mounting frame, and the size of the cutter matches the size of the support seat.

[0014] Furthermore, a wire beam laser head is fixedly installed on one side of the inner side of the mounting bracket. The wire beam laser head is close to the bottom of the cutter and matches the cutting trajectory of the cutter. The wire beam laser head is tilted downwards towards the other side of the inner side of the mounting bracket.

[0015] Furthermore, the dust collection mechanism includes an exhaust fan, a mounting base, and a dust collection box. The exhaust fan is fixedly installed on the top of the mounting frame, the mounting base is fixedly installed on the top side of the mounting frame away from the support seat, the dust collection box is fixedly installed on the top of the mounting base, a filter screen is movably fitted inside the dust collection box, a door is hinged to one side of the dust collection box, the exhaust end of the exhaust fan is connected to one side of the dust collection box, a duct is connected to the other side of the dust collection box, and a dust collection hood is connected to the bottom end of the duct.

[0016] Furthermore, the dust collection hood is designed with an incline, and the opening of the dust collection hood is inclined toward the bottom of the cutter.

[0017] The present invention has the following advantages over the prior art:

[0018] 1. This technical solution incorporates a safe loading and unloading mechanism, allowing the printing paper to be placed at the mechanism during the cutting process. The mechanism then moves the paper below the cutting mechanism for cutting. After cutting, the paper is moved away from the cutting mechanism. Throughout this process, since workers are away from the cutting mechanism when loading and unloading paper, the safety of the cutting mechanism is effectively prevented from accidentally activating the cutting mechanism, thus greatly improving safety and practicality.

[0019] 2. This technical solution incorporates a dust collection mechanism, which effectively collects and filters paper scraps and dust generated during the cutting process of printed paper. The collected dust is then discharged as clean air, effectively preventing large amounts of debris and dust from scattering into the surrounding environment and causing cumbersome subsequent cleanup. Furthermore, it effectively prevents dust from harming nearby workers, further improving worker safety and demonstrating high practicality. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] In the description of this utility model, it should be understood that the terms "surface", "side", "gap", "peripheral", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Specific Implementation Example 1:

[0031] Reference Figures 1-5 A printing and cutting machine with safety protection includes a worktable 1. The bottom of the worktable 1 has multiple support legs. The top of the worktable 1 has two first sliding grooves 2 horizontally formed. A through movable groove 3 is formed between the two first sliding grooves 2 on the top of the worktable 1. A mounting frame 4, U-shaped, is fixedly installed on the top of the worktable 1. A safety loading and unloading mechanism 5 includes a bearing seat 501, a lead screw 502, and a motor 503. The bottom of the bearing seat 501 is slidably connected to the two first sliding grooves 2 via multiple sliding connectors, and the bearing seat 501 is located away from the mounting frame 4. An L-shaped limiter is fixedly installed on the top of the bearing seat 501. The top of the positioning plate 504 and the support base 501 is stacked with printing paper 505, with two sides of the printing paper 505 respectively abutting the inner corners of the limiting plate 504. The lead screw 502 is rotatably mounted on the bottom of the worktable 1 through two bearing seats. The lead screw 502 is screwed to the outside of the slider 506. The top of the slider 506 passes through the movable groove 3 and is fixedly connected to the bottom of the support base 501. The motor 503 is fixedly mounted on the bottom of the worktable 1 through the mounting parts, and the output end of the motor 503 is connected to the shaft end of the lead screw 502. The cutting mechanism 6 is located inside the mounting frame 4. The dust collection mechanism 7 is located on the top and one side of the mounting frame 4.

[0032] The top of the support base 501 has two longitudinally formed second sliding grooves 507. An L-shaped abutment seat 508 is slidably installed in each of the second sliding grooves 507. One side of the abutment seat 508 is in contact with one side of the printing paper 505. An abutment knob 509 is screwed onto the abutment seat 508, and the bottom end of the abutment knob 509 abuts against the top of the support base 501. The cutting mechanism 6 includes a fixed base 601, a cylinder 602, a lifting base 603, and a cutter 604. The fixed base 601 is fixedly installed inside the mounting frame 4. Two cylinders 602 are provided, both of which are through-type. The lifting seat 603 is fixedly installed at the fixed base 601. The top of the lifting seat 603 is fixedly connected to the telescopic ends of the two cylinders 602. The cutter 604 is fixedly installed at the bottom of the lifting seat 603. The size of the lifting seat 603 is smaller than the internal size of the mounting frame 4. The size of the cutter 604 matches the size of the bearing seat 501. A wire beam laser head 605 is fixedly installed on one side of the inside of the mounting frame 4. The wire beam laser head 605 is close to the bottom of the cutter 604 and matches the cutting trajectory of the cutter 604. The wire beam laser head 605 is tilted downward towards the other side of the inside of the mounting frame 4.

[0033] In the specific implementation process, when cutting the printing paper 505, the printing paper 505 can first be placed on the carrier 501, and its two sides should be aligned with the inner corners of the limiting plate 504. Then, with the help of the two second sliding grooves 507, the position of the abutment seat 508 is adjusted so that the abutment seat 508 and the printing paper 505 are tightly abutted together. The abutment knob 509 is then rotated until it is tightly abutted against the carrier 501, which can effectively limit and fix the printing paper 505, facilitating subsequent neat cutting. After the paper is placed, adjusted, and fixed, the motor 503 can be started to drive the lead screw 502 to rotate. The rotation of the lead screw 502 drives the slider 506 to move, which in turn moves the two second sliding grooves 507. A slide 2 drives the carrier 501 and the printing paper 505 to move horizontally until the printing paper 505 moves to a suitable position below the cutting mechanism 6. The cutting process of the printing paper 505 can then begin. After the cutting process is completed, the motor 503 works again to drive the carrier 501 to reset, so that the printing paper 505 is away from below the cutting mechanism 6. After releasing the abutment knob 509 to adjust the position of the abutment seat 508, the feeding work can begin. In the above process, since the workers are away from the cutting mechanism 6 when putting in and taking out the paper, it can effectively prevent the workers' hands from being accidentally injured by the cutting mechanism 6, thereby greatly improving the safety protection effect.

[0034] The abutment seat 508 can work with the limiting plate 504 to effectively limit and fix the stacked printing paper 505, thereby improving the neatness and stability of the subsequent cutting of the printing paper 505 and thus improving the cutting quality.

[0035] During the cutting process, the lifting seat 603 and the cutter 604 can be moved down by the operation of two cylinders 602. After the cutter 604 moves down to contact the printing paper 505, the printing paper 505 can be cut.

[0036] The size of the lifting seat 603 is smaller than the internal size of the mounting frame 4 to avoid sliding friction and movement obstruction between the lifting seat 603 and the mounting frame 4 when the lifting seat 603 moves up and down. The size of the cutter 604 matches the size of the carrier seat 501 to ensure that the cutter 604 can complete the cutting process of the paper on the carrier seat 501.

[0037] Among them, the wire beam laser head 605 can assist the operator in aligning the cutting trajectory of the cutter 604 with the cutting line on the printing paper 505 during the cutting process. Specific Implementation Example 2:

[0039] Reference Figure 3 and Figure 6 In a preferred embodiment, the dust collection mechanism 7 includes an exhaust fan 701, a mounting base 702, and a dust collection box 703. The exhaust fan 701 is fixedly installed on the top of the mounting frame 4. The mounting base 702 is fixedly installed on the top of the side of the mounting frame 4 away from the support base 501. The dust collection box 703 is fixedly installed on the top of the mounting base 702. A filter screen plate 704 is movably installed inside the dust collection box 703. A door 705 is hinged to one side of the dust collection box 703. The exhaust end of the exhaust fan 701 is connected to one side of the dust collection box 703. A duct 706 is connected to the other side of the dust collection box 703. The bottom end of the duct 706 is connected to a dust collection hood 707.

[0040] The dust collection hood 707 is designed with an angle, and the opening of the dust collection hood 707 is angled towards the bottom of the cutter 604.

[0041] In the specific implementation process, when cutting the printing paper 505, the exhaust fan 701, in conjunction with the dust collection box 703 and the duct 706, generates suction at the dust collection hood 707 to effectively draw paper scraps and dust that may be generated during cutting into the dust collection box 703. The dust is then intercepted by the filter plate 704 and retained in the dust collection box 703. Finally, clean air is discharged, which effectively prevents a large amount of scraps and dust from drifting into the surrounding environment, thus avoiding complicated subsequent cleaning work. It also effectively prevents dust from harming nearby workers, further improving the safety protection of workers.

[0042] The dust collection hood 707 is tilted towards the bottom of the cutter 604, which can better absorb and transport paper scraps and dust generated during cutting.

[0043] Working principle: When cutting printing paper 505, first place the printing paper 505 on the carrier 501, ensuring its sides are aligned with the inner corners of the limiting plate 504. Then, with the help of the two second sliding grooves 507, adjust the position of the abutment 508 so that it abuts tightly against the printing paper 505. Rotate the abutment knob 509 until it abuts tightly against the carrier 501, thus effectively limiting and fixing the printing paper 505, facilitating neat cutting later. After the paper is placed, adjusted, and fixed, start the motor 503 to rotate the lead screw 502. The rotation of the lead screw 502 moves the slider 506, coordinating with the two first sliding grooves. The groove 2 drives the carrier 501 and the printing paper 505 to move horizontally until the printing paper 505 moves to a suitable position below the cutting mechanism 6. Then the cutting process of the printing paper 505 can begin. After the cutting process is completed, the motor 503 works again to drive the carrier 501 to reset, so that the printing paper 505 is away from the bottom of the cutting mechanism 6. After releasing the abutment knob 509 to adjust the position of the abutment seat 508, the feeding work can begin. In the above process, since the workers are away from the cutting mechanism 6 when putting in and taking out the paper, it can effectively prevent the workers' hands from being accidentally started by the cutting mechanism 6, thus greatly improving the safety protection effect.

[0044] When cutting the printing paper 505, the exhaust fan 701, in conjunction with the dust collection box 703 and the duct 706, generates suction at the dust collection hood 707 to effectively draw paper scraps and dust that may be generated during cutting into the dust collection box 703. The dust is then intercepted by the filter plate 704 and retained in the dust collection box 703. Finally, clean air is discharged, which effectively prevents a large amount of debris and dust from drifting into the surrounding environment, thus avoiding complicated subsequent cleaning work. It also effectively prevents dust from harming nearby workers, further improving the safety protection of workers.
