Description

Technical Field

[0001] This utility model relates to the field of printing press cutting technology, and in particular to a cutting structure that is easy to position. Background Technology

[0002] Digital printing presses are computer-controlled, directly converting digital files into printable physical images. Their core technology lies in image processing and precise printhead control, ensuring output image quality comparable to traditional offset printing. Digital printing technology is mainly divided into two types: inkjet printing and thermal transfer printing. Inkjet printing uses high-speed printheads to spray ink onto the substrate, enabling rapid printing of images and text. It boasts faster production speeds, lower costs, and more flexible customization capabilities, supporting printing needs for various materials and sizes. Thermal transfer printing, on the other hand, uses heat to sublimate the ink on transfer paper onto the substrate, and is commonly used for printing on special materials such as textiles.

[0003] An existing patent (publication number: CN218809435U) discloses "This utility model discloses an automatic cutting device for printing presses that can be automatically positioned, relating to the field of printing press technology. This utility model includes an upper cover and a lower cover, which are interlocked. In use, the upper and lower covers form a sealed cavity, which can be used for printing on paper. Two sets of electric push rods are detachably connected to the front of the upper and lower covers. The output end of each electric push rod is fixed with an abutment strip. When the output end of the electric push rod drives the abutment strip to abut against the printing paper, the printing paper can be fixed inside the sealed cavity. This automatic cutting device for printing presses, by setting electric push rods and a cutting structure connected to the front of the upper and lower covers, and fixing the output end of the electric push rod with an abutment strip, solves the problem that existing automatic cutting devices for printing presses easily cause the printed paper to be cut at an angle."

[0004] In the process of realizing this application, the inventors discovered the following problems with the prior art: the existing cutting structure uses a rodless cylinder in conjunction with multiple push cylinders and a blade holder to achieve the cutting function. Although it improves the cutting efficiency to a certain extent, its structure is complex and requires multiple cylinders to work together, resulting in high equipment costs.

[0005] Therefore, those skilled in the art have provided a cutting structure that facilitates positioning to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cutting structure that facilitates positioning. Through the cooperation of an electric telescopic rod, gear and rack transmission, and springs and pressure plates, the printed paper is firmly clamped, ensuring that the paper remains stable during the cutting process, improving cutting accuracy, and reducing overall costs.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A cutting structure for easy positioning includes an upper cover, a lower cover at the lower end of the upper cover, and a cutting mechanism disposed between the interior of the upper cover and the lower cover. The cutting mechanism includes an electric telescopic rod and a second connecting plate. A first connecting plate is fixedly disposed at the output end of the electric telescopic rod. Fixing plates are fixedly disposed on both sides of the second connecting plate and the first connecting plate. Multiple springs are fixedly disposed at the lower ends of multiple fixing plates. Racks are fixedly disposed at the front and rear ends of the first connecting plate and the second connecting plate. Gears are rotatably disposed at the front and rear ends of one side of the upper cover.

[0009] A motor is fixedly installed at the front end of the lower cover, and a bidirectional lead screw is fixedly installed at the output end of the motor. Two sliders are externally threaded to the bidirectional lead screw, and guide grooves are opened on the opposite side of the two sliders.

[0010] Furthermore, the multiple racks are meshed on opposite sides of the two gears, and the opposite ends of the multiple racks are slidably disposed at the front and rear ends inside the upper and lower covers.

[0011] Furthermore, the electric telescopic rod is externally fixedly installed on one side of the upper inside of the upper cover, and the first connecting plate and the second connecting plate are both externally slidably installed on one side of the upper and lower covers.

[0012] Furthermore, multiple pressure plates are fixedly arranged between the lower ends of the multiple springs, and multiple guide rods are fixedly arranged on opposite sides of each pair of pressure plates, with the interiors of the multiple springs respectively sleeved on the exteriors of the multiple guide rods.

[0013] Furthermore, the guide rods are slidably disposed inside the multiple fixed plates, and a cutter is fixedly disposed at the lower end of the first connecting plate.

[0014] Furthermore, both sliders are slidably disposed inside the upper and lower covers, and a sensor is fixedly disposed on one side inside the lower cover.

[0015] Furthermore, multiple conveying rollers are rotatably arranged inside the upper and lower covers, and printing structures are provided inside both the upper and lower covers.

[0016] This utility model has the following beneficial effects:

[0017] 1. The present invention proposes a cutting structure that facilitates positioning. When the printing paper is conveyed to the preset cutting position, the output end of the electric telescopic rod pushes the first connecting plate to move downward inside the printing machine. Through gears and racks, the second connecting plate moves relative to the first connecting plate, so that the pressure plate can firmly clamp and fix the printing paper, effectively preventing the paper from shifting during the cutting process and ensuring the cutting accuracy. Subsequently, the guide rod will slide inside the fixed plate, so that the cutter will cut the printing paper, thereby completing the entire printing and cutting process. While ensuring the cutting quality, it reduces the equipment cost and complexity.

[0018] 2. This utility model proposes a cutting structure that facilitates positioning. During the paper conveying process, sensors monitor the paper's position in real time. If any paper misalignment is detected, the motor immediately starts, driving a bidirectional lead screw to rotate. As the lead screw rotates, two sliders move towards each other. The guide grooves on the sliders precisely position and adjust the printing paper, ensuring it returns to the correct position and guaranteeing printing accuracy. The continuous operation of the conveyor rollers allows the printing structure to smoothly print on the paper surface. Attached Figure Description

[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figures 1-7 One embodiment provided by this utility model:

[0030] A cutting structure for easy positioning includes an upper cover 1, a lower cover 2 at the lower end of the upper cover 1, and a cutting mechanism 8 disposed between the upper cover 1 and the lower cover 2. The cutting mechanism 8 includes an electric telescopic rod 808 and a second connecting plate 810. A first connecting plate 809 is fixedly disposed at the output end of the electric telescopic rod 808. Fixing plates 804 are fixedly disposed on both sides of the second connecting plate 810 and the first connecting plate 809. Multiple springs 807 are fixedly disposed at the lower ends of the multiple fixing plates 804. Racks 803 are fixedly disposed at both the front and rear ends of the first connecting plate 809 and the second connecting plate 810. Gears 802 are rotatably disposed at both the front and rear ends of one side of the upper cover 1.

[0031] Multiple racks 803 are meshed on opposite sides of two gears 802. The opposite ends of the multiple racks 803 are slidably disposed inside the upper cover 1 and the lower cover 2. An electric telescopic rod 808 is fixedly disposed on the upper side of the upper cover 1. The first connecting plate 809 and the second connecting plate 810 are both slidably disposed inside the upper cover 1 and the lower cover 2. Multiple pressure plates 806 are fixedly disposed between the lower ends of multiple springs 807. Multiple guide rods 805 are fixedly disposed on opposite sides of the two pressure plates 806. The multiple springs 807 are respectively sleeved on the outside of the multiple guide rods 805. The multiple guide rods 805 are slidably disposed inside the multiple fixed plates 804. A cutter 801 is fixedly disposed at the lower end of the first connecting plate 809. Multiple conveying rollers 9 are rotatably disposed inside the upper cover 1 and the lower cover 2. A printing structure 3 is disposed inside the upper cover 1 and the lower cover 2.

[0032] Specifically, when the paper is transported to the printing area by the conveyor roller 9, the printing structure 3 is immediately activated. High-precision printing is completed on the paper surface using inkjet or thermal transfer technology. The printing structure 3 is a mature and publicly available technology; therefore, its specific structure and working principle will not be elaborated upon here. Once the paper reaches the preset cutting position, the electric telescopic rod 808 begins to move. Its output end pushes the first connecting plate 809 downwards along the internal guide rail of the printing press. Since the racks 803 on both sides of the first connecting plate 809 are tightly meshed with the gears 802, when moving downwards, the racks 803 drive the gears 802 to rotate synchronously, thereby driving the racks 803 on both sides of the second connecting plate 810 to move in the opposite direction, causing the second connecting plate 810 to quickly approach the first connecting plate 809. During this process, the fixing plate 804 moves synchronously, driving the pressure plate 806 to firmly clamp the paper with appropriate pressure, effectively eliminating the risk of paper displacement during cutting. As the first connecting plate 809 and the second connecting plate 810 continue to move downwards… The guide rod 805 slides within the guide hole of the fixed plate 804, ensuring that the pressure plate 806 presses down vertically to prevent deviation during cutting. At this time, the spring 807 is compressed and contracts. As the output end of the electric telescopic rod 808 continues to extend, the first connecting plate 809 reaches the set position. The cutter 801 at its lower end completes the paper cutting process instantly with precise mechanical movement, thereby ensuring the accurate position of the material during cutting and improving cutting accuracy. While ensuring cutting efficiency and quality, it achieves higher production flexibility and economic benefits at a lower cost. During subsequent maintenance, the upper cover 1 and the lower cover 2 are connected by detachable bolts. The spring 807 is made of high-quality stainless steel, which can maintain stable elasticity during long-term use. Rubber blocks are provided on opposite ends of the pressure plate 806, and the opposite ends of the rubber blocks have diamond-shaped anti-slip textures to improve the stability of fixing the printed paper. During subsequent maintenance, the upper cover 1 and the lower cover 2 can be separated simply by loosening the bolts, which facilitates the inspection and replacement of the cutting mechanism 8 and transmission components.

[0033] Reference Figures 1-5 A motor 6 is fixedly installed at the front end of the inner side of the lower cover 2. A two-way lead screw 4 is fixedly installed at the output end of the motor 6. Two sliders 5 are externally threaded to the two-way lead screw 4. Guide grooves 7 are opened on the opposite side of the two sliders 5.

[0034] Both sliders 5 are slidably disposed inside the upper cover 1 and the lower cover 2, and a sensor 10 is fixedly disposed on one side of the lower cover 2.

[0035] Specifically, in actual operation, the operator only needs to smoothly insert the printing paper into the special insertion interface on one side of the upper cover 1 and the lower cover 2. Then, the conveyor roller 9 inside the printing press quickly starts to assist the smooth conveying of the paper at a precise and constant speed. During the paper conveying process, the sensor 10 monitors the paper position in real time. The sensor 10 is an existing photoelectric sensor 10 used to detect the edge position of the paper. When the paper deviates and causes the sensor 10 to receive an abnormal signal, the motor 6 will automatically respond and drive the bidirectional lead screw 4 to rotate at high speed. The two sliders 5 move towards each other under the drive of the bidirectional lead screw 4. The guide groove 7 on the opposite side can physically limit the edge of the paper, correct the paper deviation, ensure the cutting position is accurate, and realize automatic correction. The printing press consists of the upper cover 1 and the lower cover 2. The printing press and its internal conveyor roller 9 are both mature and publicly available technologies. Therefore, their specific structure and working principle will not be described in detail in this document. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0036] Working principle: When in use, the operator first inserts the printing paper into the insertion interface on one side of the upper cover 1 and the lower cover 2. Then, the conveyor roller 9 inside the printing machine starts, which can assist in the conveying of the printing paper. During the transport of the printing paper, the sensor 10 will sense the position of the paper. When the paper deviates, the motor 6 starts, which will drive the bidirectional lead screw 4 to rotate, causing the two sliders 5 to move towards each other. The guide groove 7 on the slider 5 can position the printing paper, realize the adjustment of the position of the printing paper, and make the printing paper in the correct position. The continued transport of the conveyor roller 9 will cause the printing structure 3 to print on the surface of the printing paper.

[0037] When the printing paper moves to the set position, the output end of the electric telescopic rod 808 will push the first connecting plate 809 to slide downward inside the printing press. Since the racks 803 on both sides of the first connecting plate 809 mesh with the gears 802, when the first connecting plate 809 moves downward, the racks 803 will drive the gears 802 to rotate. The rotation of the gears 802 will drive the racks 803 on both sides of the second connecting plate 810 to move, thereby bringing the second connecting plate 810 and the first connecting plate 809 closer together and causing the fixed plate 804 to move synchronously relative to each other, so that the pressure plate 806 clamps the printing paper to prevent the printing paper from shifting. The continued movement of the first connecting plate 809 and the second connecting plate 810 will cause the guide rod 805 to slide inside the fixed plate 804 and cause the spring 807 to contract. When the first connecting plate 809 moves to the set position, the cutter 801 at its lower end will cut the printing paper.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
