Description

Technical Field

[0001] This invention belongs to the field of printing technology, and in particular relates to a self-protective printing device. Background Technology

[0002] Printing is a technology that involves transferring ink from original manuscripts such as text, pictures, photographs, and anti-counterfeiting materials to the surface of materials like paper through processes such as plate making, inking, and pressure application, thus mass-producing the content of the original. In paper printing, printing equipment is often required. Existing printing equipment typically feeds paper into the machine, and a pushing component moves the paper within the machine while the printing end prints on the paper simultaneously. However, traditional printing equipment continues to operate regardless of whether there is no paper replenishment or no ink, resulting in ink waste or blank paper. Summary of the Invention

[0003] In view of this, the present invention aims to provide a self-protective printing device to solve the technical problem that the traditional cutting method can only cut the paper once per operation, resulting in wasted power when the cutting device resets.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a self-protective printing device, comprising a conveying component, a printing component mounted on the conveying component, the conveying component and the printing component being connected by a transmission component, the transmission component being connected to a power output device, the printing component being connected to an ink supply device, and a paper monitoring device mounted on the conveying component. The ink supply device detects that it has insufficient ink, or the paper monitoring device detects that no paper has entered between the conveying component and the printing component, which will cause the power output device to stop transmitting power to the transmission component.

[0005] Furthermore, the conveying assembly includes a mounting frame on which multiple auxiliary wheels and two extrusion wheels are rotatably mounted. The auxiliary wheels and extrusion wheels are equipped with transmission belts. The extrusion part of the transmission belt is attached to the printing assembly. The transmission assembly connects the extrusion wheels and the printing assembly.

[0006] Furthermore, the printing assembly includes a fixed column, which is mounted on a mounting frame. A printing section is rotatably mounted on the fixed column. An ink supply device supplies ink to the printing section through the fixed column. The printing section and the extrusion roller are connected by a transmission assembly.

[0007] Furthermore, the fixed column is equipped with a rotatable feeding pipe, a feeding groove, an opening, and a baffle. An arc spring is provided between the baffle and the fixed column. The feeding pipe and the printing section are in frictional engagement. The rotation of the printing section drives the feeding pipe to rotate and further compresses the arc spring. The opening is connected to the feeding groove, which replenishes ink to the printing section.

[0008] Furthermore, the printing section includes a rotating disk rotatably mounted on a fixed column. The rotating disk has a printed layer and a non-printed layer, the dimensions of which are adjustable. The rotating disk is equipped with a rotating sleeve that frictionally engages with a feed pipe. The rotating sleeve and the extrusion wheel are connected via a transmission assembly.

[0009] Furthermore, the transmission assembly includes a first gear and a second gear. The first gear is mounted on a rotating sleeve, and the second gear is mounted on a pressing wheel. The first gear and the second gear mesh, and the rotating sleeve receives power from the power output device.

[0010] Furthermore, the power output device includes a mounting base, a transmission plate on the mounting base, fixed tubes on both sides of the transmission plate, a sliding rod inside the fixed tube, a shrinker on the mounting base, the shrinker connected to the sliding rods on both sides, a first transmission plate on the sliding rod, a second transmission plate on the rotating sleeve, a third transmission plate on the matching servo motor, the first transmission plates on both sides connected to the second and third transmission plates, and an ink supply device and a paper monitoring device drive the shrinker to move the first transmission plate closer to the transmission plate.

[0011] Furthermore, the ink replenishment device includes a storage tank and a feed pipe connected together. A float is provided inside the storage tank, and a connecting bolt is provided on the float. A fixed cylinder is provided on the storage tank, and the connecting bolt slides inside the fixed cylinder. A first transmitter is provided at the lower end of the fixed cylinder. After the connecting bolt squeezes the first transmitter and causes a pressure change, it sends a signal to the shrinker to drive the shrinker to move the first transmission disc.

[0012] Furthermore, the paper monitoring device includes a detection cylinder, which is mounted on the mounting frame via a fixing bracket. A pressure plug is slidably provided inside the detection cylinder, and a second transmitter is provided inside the detection cylinder. A rotating wheel is provided at the lower end of the pressure plug, and a groove is provided in the center of the transmission belt, into which the rotating wheel can slide.

[0013] Beneficial effects: The conveying and printing components are driven by the transmission component to move the paper between them. During the paper movement, the printing component prints on the paper passing between them. When the ink supply device is insufficient or no new paper enters between the conveying and printing components, the power output device disconnects from the transmission component, and then the conveying and printing components stop operating.

Detailed Implementation

[0015] As shown in the figure, a self-protective printing device includes a conveying component 1, on which a printing component 2 is mounted. The conveying component 1 and the printing component 2 are connected by a transmission component 3. The transmission component 3 is connected to a power output device 4. The printing component 2 is connected to an ink supply device 5. The conveying component 1 is equipped with a paper monitoring device 6. When the ink supply device 5 detects that it has insufficient ink or when the paper monitoring device 6 detects that no paper is entering between the conveying component 1 and the printing component 2, it will drive the power output device 4 to stop transmitting power to the transmission component 3.

[0016] The conveying component 1 and the printing component 2 are pushed by the transmission component 3 to move the paper between them. During the paper movement, the printing component 2 prints on the paper passing between them. When the amount of ink in the ink supply device 5 is insufficient or no new paper enters between the conveying component 1 and the printing component 2, the power output device 4 disconnects from the transmission component 3, and then the conveying component 1 and the printing component 2 stop operating.

[0017] In this embodiment, the conveying assembly 1 includes a mounting frame 1-1, on which a plurality of auxiliary wheels 1-2 and two extrusion wheels 1-3 are rotatably mounted. The auxiliary wheels 1-2 and the extrusion wheels 1-3 are provided with a transmission belt 1-4. The extrusion part of the extrusion wheel 1-3 is pressed by the transmission belt 1-4 and attached to the printing assembly 2. The transmission assembly 3 connects the extrusion wheel 1-3 and the printing assembly 2.

[0018] In this embodiment, the printing assembly 2 includes a fixed post 2-1, which is mounted on the mounting frame 1-1. A printing section is rotatably mounted on the fixed post 2-1. An ink supply device 5 supplies ink to the printing section through the fixed post 2-1. The printing section and the extrusion roller 1-3 are connected by a transmission assembly 3. A feeding pipe 2-3 is rotatably mounted inside the fixed post 2-1. A feeding groove 2-2 is also provided inside the fixed post 2-1. An opening 2-4 is provided on the feeding pipe 2-3. A baffle 2-5 is provided on the feeding pipe 2-3. An arc spring 2-6 is provided between the baffle 2-5 and the fixed post 2-1. The feeding pipe 2-3 and the printing section are in frictional engagement. The rotation of the printing section drives the feeding pipe 2-3 to rotate and further compresses the arc spring 2-6. The opening 2-4 and the feeding groove 2-2 are connected. -2 Replenishes ink to the printing section, which includes a rotating disk 2-7 rotatably mounted on a fixed column 2-1. The rotating disk 2-7 has a printed layer 2-8 and a non-printed layer 2-9, the dimensions of which are adjustable. The rotating disk 2-7 has a rotating sleeve 2-10, which is in frictional engagement with the feed pipe 2-3. The rotating sleeve 2-10 and the extrusion wheel 1-3 are connected by a transmission assembly 3. The transmission assembly 3 includes a first gear 3-1 and a second gear 3-2. The first gear 3-1 is mounted on the rotating sleeve 2-10, and the second gear 3-2 is mounted on the extrusion wheel 1-3. The first gear 3-1 and the second gear 3-2 mesh. The rotating sleeve 2-10 receives power from the power output device 4.

[0019] Rotating sleeve 2-10 drives the first gear 3-1 to rotate. The first gear 3-1 drives the extrusion wheel 1-3 to rotate via the second gear 3-2. The extrusion wheel 1-3 drives the transmission belt 1-4 to rotate. Rotating sleeve 2-10 drives rotating disk 2-7 to rotate. Rotating disk 2-7 drives printing layer 2-8 to rotate. At the same time as rotating sleeve 2-10, it drives feeding pipe 2-3 to rotate at a certain angle so that opening 2-4 and feeding groove 2-2 are connected. Then, whenever printing layer 2-8 rotates to the position of feeding groove 2-2, feeding groove 2-2 supplies ink to printing layer 2-8. Printing layer 2-8 with ink pushes the paper to move while printing on the paper. When operation stops, the compressed printing layer 2-8 pushes baffle 2-5 to rotate. Baffle 2-5 drives feeding pipe 2-3 to rotate, so that opening 2-4 and feeding groove 2-2 are separated to prevent ink leakage. Printing layer 2-8 can be freely replaced to adjust the pattern and printing size.

[0020] In this embodiment, the power output device 4 includes a mounting base 4-1, a transmission disk 4-2 on the mounting base 4-1, fixed tubes 4-3 on both sides of the transmission disk 4-2, and a moving rod 4-4 slidingly disposed inside the fixed tubes 4-3. A shrinker 4-7 is mounted on the mounting base 4-1, connected to the moving rods 4-4 on both sides. A first transmission disk 4-5 is mounted on the moving rods 4-4, a second transmission disk 4-6 is mounted on the rotating sleeve 2-10, and a third transmission disk 4-7 is mounted on a matching servo motor. The first transmission disks 4-5 on both sides are connected to the second transmission disk 4-6 and the third transmission disk 4-7. The ink supply device 5 and the paper monitoring device 6 drive the shrinker 4-7 to move the first transmission disk 4-5 closer to the transmission disk 4-2. The ink supply device 5 includes a storage tank 5-1 and a feeding pipe 2. -3 connection, the storage box 5-1 is equipped with a float 5-2 inside, the float 5-2 is equipped with a connecting bolt 5-3, the storage box 5-1 is equipped with a fixed cylinder 5-4, the connecting bolt 5-3 slides inside the fixed cylinder 5-4, the lower end of the fixed cylinder 5-4 is equipped with a first transmitter 5-5, after the connecting bolt 5-3 squeezes the first transmitter 5-5 and the pressure changes, it sends a signal to the shrinker 4-7 to drive the shrinker 4-7 to drive the first transmission disc 4-5 to move. The paper monitoring device 6 includes a detection cylinder 6-1, the detection cylinder 6-1 is set on the mounting frame 1-1 through a fixed frame, the detection cylinder 6-1 is equipped with a pressure bolt 6-2 sliding inside, the detection cylinder 6-1 is equipped with a second transmitter 6-3 inside, the lower end of the pressure bolt 6-2 is equipped with a rotating wheel 6-4, the center of the transmission belt 1-4 is equipped with a groove 1-5, the rotating wheel 6-4 can slide into the groove 1-5.

[0021] The third transmission disc 4-7 drives the moving rod 4-4 to rotate via the first transmission disc 4-5. The moving rod 4-4, through the fixed tube 4-3, drives the transmission disc 4-2 to rotate. The transmission disc 4-2, through the first transmission disc 4-5, the moving rod 4-4, and the fixed tube 4-3, drives the second transmission disc 4-6 to rotate. The second transmission disc 4-6 drives the rotating sleeve 2-10 to rotate. When the ink level inside the storage box 5-1 is insufficient, the float 5-2 falls, causing the connecting bolt 5-3 to move and squeeze the first emitter 5-5. After the pressure changes, the first emitter 5-5 fires towards the retractor 4-7. The signal drives the shrinker 4-7 to move the first transmission disc 4-5, bringing it closer to the transmission disc 4-2. When there is no paper, the pressure plug 6-2 inside the detection cylinder 6-1 falls and squeezes the second transmitter 6-3. After being squeezed, the second transmitter 6-3 sends a signal to the shrinker 4-7, causing the shrinker 4-7 to move the first transmission disc 4-5 closer to the transmission disc 4-2, disconnecting the power output. Only when neither of them sends a signal to the shrinker 4-7 can the servo motor transmit power to the rotating sleeve 2-10.
