Description

Technical Field

[0001] The utility model relates to the technical field of printers, in particular to a roller pressing structure of a printer. Background Art

[0002] A printer is a device that prints computer processing results on media such as paper. It is one of the important output devices of a computer. With the development of science and technology, printers are also constantly developing towards a more efficient, smarter and more environmentally friendly direction. For example, the emergence of technologies such as wireless printing and cloud printing has made printing more convenient. In a printer, the roller structure is one of the core components, and its design directly affects the printing quality and efficiency. The printer roller structure plays a vital role in the printing process, and its performance and stability directly affect the printing quality and efficiency. The working principle of the printer roller structure is based on the principles of friction transmission and mechanical positioning. During the printing process, the driving component drives the paper pressing roller to rotate through the transmission gear, and the paper pressing roller contacts the paper and applies appropriate pressure. As the paper pressing roller rotates, the paper moves forward under the action of friction, and is constrained and positioned by the guide component to ensure the accuracy and stability of printing. Utility Model Content

[0003] The purpose of the utility model is to provide a roller pressing structure of a printer, which flattens the printing material before fixing, thereby solving the problem that the printing structure is not aesthetically pleasing due to the curled edges and wrinkles on the surface of the printing material before fixing.

[0004] The utility model is realized through the following technical solutions:

[0005] The utility model is a roller pressing structure of a printer, comprising a machine body, a rotating roller and a fixing mechanism. The machine body comprises a casing, a workbench is arranged inside the casing, a support frame is installed on one side of the workbench, and a support plate is arranged on the other side. A through hole is opened on the support frame, and a support shaft is arranged on the support plate. The rotating roller has a blind hole end and a rotating shaft end, the blind hole end cooperates with the support shaft, and the rotating shaft end cooperates with the through hole. A flattening mechanism is arranged at the rotating shaft end, and a notch is opened on the workbench.

[0006] The flattening mechanism includes a flattening plate and a telescopic driving rod. The flattening plate is arranged at the end of the telescopic driving rod. The telescopic driving rod is located just above the slot. When the telescopic driving rod is working, the flattening plate moves along the slot direction of the slot.

[0007] Furthermore, a transverse groove is provided on the workbench, an ink supply roller is installed in the transverse groove, and the transverse groove is located directly below the rotating roller.

[0008] Furthermore, the flattening mechanism also includes a bending cylinder, which is fitted in the through hole of the support frame, the end of the rotating shaft is fitted in the end hole of the bending cylinder, and a fixed sleeve is installed at the other end of the bending cylinder. A connecting rod is provided on the fixed sleeve, and the connecting rod is fitted with the sliding sleeve. A mounting frame is provided on the sliding sleeve, and the end of the telescopic drive rod is fixed in the mounting frame.

[0009] Furthermore, a guide hole plate is provided on the workbench, and the telescopic driving rod passes through the guide hole plate.

[0010] Furthermore, the fixing mechanism includes a fixing cylinder and a connecting plate. The fixing cylinder is provided with a connecting plate. The top end of the connecting plate is connected to the bottom end of the pressing plate. The fixing cylinder is sleeved on the ink supply roller.

[0011] The utility model has the following beneficial effects:

[0012] This utility model:

[0013] 1. Through the mutual cooperation between the bending cylinder, the connecting rod, the telescopic drive rod and the pressing plate, the fixed sleeve is fixed to the swinging end of the bending cylinder, so when one end of the bending cylinder swings, the connecting rod swings, and the sliding sleeve slides on the surface of the connecting rod. When the sliding sleeve slides, the part connected to the telescopic drive rod is hinged, so that the outer surface of the telescopic drive rod slides inside the guide hole plate, so that the pressing plate flattens the corners and surface of the substrate, thereby preventing wrinkles and warping of corners on the surface of the substrate. Wrinkles and warping of corners appear on the substrate before fixing, resulting in uneven ink distribution during fixing, blurred printing, double images or missing prints. Flattening it with the pressing plate can ensure that the surface of the substrate is flat and reduce the occurrence of these printing defects.

[0014] 2. Through the cooperation between the ink supply roller and the fixing cylinder, the ink supply roller can replenish ink on the surface of the fixing cylinder in time to prevent the fixing cylinder from running out of ink when fixing the substrate. Since the adhesion of ink to the substrate is the key factor to ensure the durability of the printed image, when the fixing cylinder is fixing, insufficient ink will cause the adhesion between the ink and the substrate to weaken, making the printed image easy to fall off or blur, which not only affects the durability of the printed product, but may also cause difficulties in subsequent use or processing.

[0015] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-5 The utility model provides a technical solution: a roller pressing structure of a printer includes a body 100, a rotating roller 105 and a fixing mechanism 300. The body 100 includes a shell 101, a workbench 102 is arranged inside the shell 101, a support frame 103 is installed on one side of the workbench 102, and a support plate 104 is arranged on the other side. A through hole is opened on the support frame 103, and a support shaft is provided on the support plate 104. The rotating roller 105 is set up by the support frame 103 and the support plate 104. The rotating roller 105 has a blind hole end and a rotating shaft end. The blind hole end cooperates with the support shaft, and the rotating shaft end cooperates with the through hole. A flattening mechanism 200 is arranged at the rotating shaft end, and a slot 106 is opened on the workbench 102.

[0025] Furthermore, a transverse groove is provided on the workbench 102 , in which an ink supply roller 107 is installed. The transverse groove is located directly below the rotating roller 105 .

[0026] Preferably, the flattening mechanism 200 also includes a bending cylinder 201, and a fixed sleeve 202 is installed at the other end of the bending cylinder 201. The bracket composed of the bending cylinder 201, the fixed sleeve 202 and the connecting rod 203 is used to fix the end of the flattening mechanism 200. Since the bending cylinder 201 is installed on the support frame 103, the rotating shaft end of its rotating roller 105 can be fitted in the end hole of the bending cylinder 201.

[0027] A connecting rod 203 is provided on the fixed sleeve 202 , and the connecting rod 203 is matched with the sliding sleeve 204 . A mounting frame is provided on the sliding sleeve 204 , and the end of the telescopic driving rod 205 is fixed in the mounting frame.

[0028] The flattening mechanism 200 includes a flattening plate 207 and a telescopic driving rod 205. The flattening plate 207 is arranged at the end of the telescopic driving rod 205. The telescopic driving rod 205 is located directly above the slot 106. When the telescopic driving rod 205 is working, the flattening plate 207 moves along the groove direction of the slot 106. Before the printing material is fixed, the flattening plate 207 processes the warping edges and surface wrinkles of the printing material.

[0029] Preferably, a guide hole plate 206 is provided on the workbench 102 , and the telescopic driving rod 205 passes through the guide hole plate 206 , and the middle part of the telescopic driving rod 205 is supported by the guide hole plate 206 .

[0030] Furthermore, the fixing mechanism 300 is included. The fixing mechanism 300 includes a fixing cylinder 302 and a connecting plate 301. The fixing cylinder 302 is provided with a connecting plate 301. The top of the connecting plate 301 is connected to the bottom of the pressing plate 207. The fixing cylinder 302 is sleeved on the ink supply roller 107.

[0031] First, the staff puts the printing material on the housing 101, and then prints it by pressing the button of the housing 101. When the printing material enters the interior of the housing 101, the components inside the housing 101 print the printing material. After the printing is completed, the printing material is located on the upper surface of the workbench 102. Then the printing material is transported by the components inside the housing 101. When the printing material is transported to the upper surface of the slot 106, the rotating roller 105 rotates through the components inside the housing 101. The rotation of the rotating roller 105 causes the bending cylinder 201 to rotate. At this time, the other end of the bending cylinder 201 swings. Since the fixed sleeve 202 is aligned with the bending cylinder 201, the bending cylinder 201 is rotated. One end of the cylinder 201 that swings is fixed, so when one end of the bending cylinder 201 swings, the connecting rod 203 swings, and at this time the sliding sleeve 204 slides on the surface of the connecting rod 203, causing the outer surface of the telescopic driving rod 205 to slide inside the guide hole plate 206, so that the pressing plate 207 flattens the edges and surface of the substrate, thereby preventing wrinkles and warping of the edges and corners of the substrate from occurring. Wrinkles and warping of the edges and corners of the substrate before fixing lead to uneven ink distribution during fixing, resulting in blurred printing, double printing or missing printing. The flattening treatment of the pressing plate 207 ensures that the surface of the substrate is flat, thereby reducing the occurrence of these printing defects.

[0032] After the substrate is flattened, it is transferred to the gap between the support plate 104 and the ink supply roller 107 through the components inside the housing 101, so that the substrate is fixed. When the substrate is fixed, since the pressing plate 207 is connected to the connecting plate 301, when the pressing plate 207 flattens the substrate, the connecting plate 301 slides inside the slot 106 through the pressing plate 207, so that the surface of the fixing cylinder 302 fixes the surface of the substrate. 7 is placed inside the fixing cylinder 302, so the ink supply roller 107 can replenish ink on the surface of the fixing cylinder 302 in time to prevent the fixing cylinder 302 from running out of ink when fixing the substrate. Since the adhesion of ink to the substrate is a key factor in ensuring the durability of the printed image, when the fixing cylinder 302 is fixing, running out of ink will weaken the adhesion between the ink and the substrate, making the printed image easy to fall off or blur, which not only affects the durability of the printed product, but may also cause difficulties in subsequent use or processing.
