Description

Technical Field

[0001] The invention belongs to the technical field of printers, and in particular relates to a printer paper feeding structure for eliminating static electricity of consumables. Background Art

[0002] A printer is an electronic device used to convert data from a computer or other digital device into visible text or images, usually output on paper. Printers are one of the common office automation devices in offices and homes, used to print documents, reports, pictures, etc.

[0003] Thermal transfer printers are widely used and need to be compatible with a variety of consumables. The friction between the rubber roller and the thermal film will generate accumulated static electricity, which can cause several problems. One is damage to the print head and reduce its service life. The other is electric shock when replacing consumables, which poses a certain threat to life.

[0004] The static electricity elimination effect on the market is not ideal, and it is impossible to eliminate static electricity in a timely and rapid manner, which brings great problems to use. Summary of the invention

[0005] The object of the present invention is to provide a printer paper feeding structure for eliminating static electricity of consumables, so as to solve the problems raised in the above-mentioned background technology.

[0006] In view of this, the present invention provides a printer paper feeding structure for eliminating static electricity of consumables, comprising:

[0007] The upper shell and the lower shell are rotatably connected to each other;

[0008] A carbon ribbon assembly is rotatably disposed inside the upper shell and the lower shell, and the carbon ribbon assembly is used to transmit the carbon ribbon;

[0009] A paper feeding assembly is rotatably arranged inside the upper shell and the lower shell, the paper feeding assembly is adjacent to the carbon ribbon assembly, and the paper feeding assembly is used to provide paper feeding;

[0010] A paper feeding channel is formed inside the upper shell and the lower shell, the carbon ribbon portion is transmitted to an end of the paper feeding channel where the paper is discharged, and the paper feeding assembly allows the paper to pass through the paper feeding channel so that the paper and the carbon ribbon portion are fitted and matched;

[0011] A rubber roller is rotatably arranged on the lower shell, and the carbon ribbon and the paper are both rollingly matched on the rubber roller;

[0012] A printing assembly is arranged in the upper shell and cooperates with the rubber roller to print on the paper;

[0013] The printing assembly includes a thermal mechanism that cooperates with the carbon ribbon, paper and rubber roller. The thermal mechanism is arranged on the printing assembly through an adjustment mechanism. The carbon ribbon is partially wound around the lower part of the thermal mechanism. The adjustment mechanism can make the force of the thermal mechanism acting vertically on the printing assembly match the carbon ribbon tension according to the different tensions generated by different carbon ribbons, so as to adaptively adjust the carbon ribbon tension to reduce static electricity.

[0014] A balancing roller is rotatably arranged in the upper shell, the balancing roller is located above the printing component, the carbon ribbon rolls around the balancing roller, and the balancing roller is used to eliminate static electricity on the carbon ribbon.

[0015] In the present invention, a further implementation scheme is that the printing component includes a print head fixing seat, the print head fixing seat is fixed in the upper shell, the adjustment mechanism includes a spring plate, the spring plate is locked on the print head fixing seat, one end of the upper part of the thermal mechanism is bufferedly connected to the print head fixing seat through a spring, the bottom of the spring plate and the upper part of the thermal mechanism are in contact with each other, and the carbon ribbon bypasses the lower part of the thermal mechanism. When the carbon ribbon generates different pulling forces on the thermal mechanism, one end of the thermal mechanism acts on the spring plate upward or downward, so that the extrusion force of the printing mechanism on the carbon ribbon after being acted upon by the spring plate is adaptively matched with the pulling force of the carbon ribbon.

[0016] In the present invention, a further implementation scheme is that the thermal mechanism includes a thermal sheet and a thermal sheet fixing seat, one end of the upper portion of the thermal sheet fixing seat is elastically abutted against a spring, and the upper portion of the other end is elastically abutted against a spring sheet, the thermal sheet is fixedly arranged on the thermal sheet fixing seat and corresponds to the carbon ribbon and the rubber roller, and the thermal sheet corresponds to one end of the paper feeding channel where paper is discharged.

[0017] In the present invention, a further implementation scheme is that a first slope is formed between the paper feeding channel and the horizontal plane, and a second slope is formed between the thermal sheet and the horizontal plane, and the first slope is greater than the second slope, thereby reducing the contact area between the thermal sheet and the rubber roller.

[0018] In the present invention, a further implementation scheme is that the print head fixing seat is made of zinc alloy.

[0019] In a further embodiment of the present invention, the exterior of the balancing roller is coated with antistatic rubber.

[0020] In the present invention, a further implementation scheme is that it also includes a thermal film grounding wire and a print head grounding wire, the thermal film grounding wire is connected to the thermal film fixing seat, and the print head grounding wire is connected to the thermal film fixing seat and is arranged on the outer side of the upper shell.

[0021] In the present invention, a further implementation scheme is that it also includes a rubber roller grounding wire, which is connected to one end of the rubber roller and is arranged on the outer side of the lower shell.

[0022] The beneficial effects of the present invention are:

[0023] First, the present invention sets an adjustment mechanism between the print head fixing seat of the printing assembly and the thermal film fixing seat in the thermal mechanism. The adjustment mechanism is a spring. The print head fixing seat and the thermal film fixing seat are elastically connected by a spring and adaptively adjusted by the spring. The spring can be automatically and effectively adjusted according to the different pulling forces generated by different types of carbon ribbons, so that the extrusion force of the thermal mechanism on the carbon ribbon can be adaptively adapted to the pulling force of the carbon ribbon, thereby reducing the generation of static electricity.

[0024] Secondly, change the inclination of the thermal sheet so that the second inclination between the thermal sheet and the horizontal plane is smaller than the first inclination between the paper path and the horizontal plane. When the paper is fed out of the paper path, it will not completely contact the thermal sheet, thereby reducing the contact area between the thermal sheet and the rubber roller and reducing the generation of static electricity.

[0025] Third, the print head holder is made of high-quality conductive zinc alloy, which can transfer the generated static electricity to the mainboard and discharge it quickly, while also protecting the print head.

[0026] Fourthly, the outside of the balance roller is coated with anti-static rubber coating, which can quickly eliminate static electricity on the carbon ribbon and comprehensively and quickly eliminate static electricity during the printing process. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] This embodiment provides a printer paper feeding structure for eliminating static electricity of consumables, including:

[0036] The upper shell 1 and the lower shell 2 are rotatably connected to each other;

[0037] The carbon ribbon assembly 3 is rotatably arranged inside the upper shell 1 and the lower shell 2. The carbon ribbon assembly 3 is used to transmit the carbon ribbon 30. Usually, a thermal transfer printer can adapt to various types of carbon ribbons 30. The tension brought by different carbon ribbons 30 is different, so there will be certain differences in the printing process.

[0038] The paper feed assembly 4 is rotatably arranged inside the upper shell 1 and the lower shell 2. The paper feed assembly 4 is adjacent to the carbon ribbon assembly 3. The paper feed assembly 4 is used to provide paper 40 for feeding. The paper feed assembly 4 is mainly used to supply paper rolls.

[0039] A paper feeding channel 5 is formed inside the upper shell 1 and the lower shell 2, and the carbon ribbon 30 is partially transmitted to one end of the paper feeding channel 5 where the paper is discharged. The paper feeding assembly 4 provides paper 40 to pass through the paper feeding channel 5 so that the paper 40 and the carbon ribbon 30 are partially fitted and matched. The printing coordination relationship and related principles between the carbon ribbon 30 and the paper 40 during the printing process are technical means known in the existing industry and will not be elaborated in this solution.

[0040] The rubber roller 6 is rotatably arranged on the lower shell 2 , and the carbon ribbon 30 and the paper 40 are both rollingly matched on the rubber roller 6 , that is, the paper 40 directly rolls on the rubber roller 6 during the printing process.

[0041] The printing assembly 7 is disposed in the upper shell 1 and cooperates with the rubber roller 6 to print on the paper 40 .

[0042] The balancing roller 8 is rotatably arranged in the upper shell 1 . The balancing roller 8 is located above the printing component 7 . The carbon ribbon 30 rolls around the balancing roller 8 . The balancing roller 8 is used to eliminate static electricity on the carbon ribbon 30 .

[0043] The printing component 7 includes a thermal mechanism 9 that cooperates with the carbon ribbon 30, paper 40 and rubber roller 6. The thermal mechanism 9 is set on the printing component 7 through an adjusting mechanism. The carbon ribbon 30 is partially wrapped around the lower part of the thermal mechanism 9. The adjusting mechanism can make the vertical force of the thermal mechanism 9 acting on the printing component 7 match the tension of the carbon ribbon 30 according to the different tensions generated by different carbon ribbons 30, so as to adaptively adjust the tension of the carbon ribbon 30 to reduce static electricity; the traditional printing component 7 is equipped with a single spring 71, which can exert a certain force on the carbon ribbon 30, but cannot achieve adaptive adjustment according to different types of carbon ribbon components 3.

[0044] In this embodiment, the printing component 7 includes a print head fixing seat 70, and the print head fixing seat 70 is fixed in the upper shell 1. The adjusting mechanism includes a spring 10, and the spring 10 is locked on the print head fixing seat 70. One end of the upper part of the thermal mechanism 9 is buffer-connected to the print head fixing seat 70 through a spring 71. The bottom of the spring 10 and the upper part of the thermal mechanism 9 are in contact with each other, and the carbon ribbon 30 bypasses the lower part of the thermal mechanism 9. When the carbon ribbon 30 generates different pulling forces acting on the thermal mechanism 9, one end of the thermal mechanism 9 acts on the spring 10 upward or downward, so that the extrusion force of the printing mechanism on the carbon ribbon 30 after being acted upon by the spring 10 is adaptively matched with the pulling force of the carbon ribbon 30.

[0045] In this embodiment, specifically, the thermal mechanism 9 includes a thermal sheet 90 and a thermal sheet fixing seat 91. One end of the upper portion of the thermal sheet fixing seat 91 is elastically abutted against the spring 71, and the upper portion of the other end is elastically abutted against the spring 10. The thermal sheet 90 is fixedly arranged on the thermal sheet fixing seat 91 and corresponds to the carbon ribbon 30 and the rubber roller 6. The thermal sheet 90 corresponds to one end of the paper feeding channel 5 where paper is output. Since different types of carbon ribbons 30 generate different pulling forces during printing, the different pulling forces generated are used to enable the spring 10 to be effectively and automatically adjusted, so that the extrusion force of the thermal mechanism 9 on the carbon ribbon 30 is adaptively adapted to the pulling force of the carbon ribbon 30, thereby reducing the generation of static electricity and reducing the damage to the print head caused by static electricity. Example 2

[0047] The upper shell 1 and the lower shell 2 are rotatably connected to each other;

[0048] The carbon ribbon assembly 3 is rotatably arranged inside the upper shell 1 and the lower shell 2. The carbon ribbon assembly 3 is used to transmit the carbon ribbon 30. Usually, a thermal transfer printer can adapt to various types of carbon ribbons 30. The tension brought by different carbon ribbons 30 is different, so there will be certain differences in the printing process.

[0049] The paper feed assembly 4 is rotatably arranged inside the upper shell 1 and the lower shell 2. The paper feed assembly 4 is adjacent to the carbon ribbon assembly 3. The paper feed assembly 4 is used to provide paper 40 for feeding. The paper feed assembly 4 is mainly used to supply paper rolls.

[0050] The paper feed channel 5 is formed inside the upper shell 1 and the lower shell 2, and the carbon ribbon 30 is partially transmitted to one end of the paper feed channel 5 where the paper is discharged. The paper feed assembly 4 provides the paper 40 to pass through the paper feed channel 5 so that the paper 40 and the carbon ribbon 30 are partially fitted and matched. The printing coordination relationship and related principles between the carbon ribbon 30 and the paper 40 during the printing process are technical means known in the existing industry and will not be elaborated in this solution.

[0051] The rubber roller 6 is rotatably arranged on the lower shell 2 , and the carbon ribbon 30 and the paper 40 are both rollingly matched on the rubber roller 6 , that is, the paper 40 directly rolls on the rubber roller 6 during the printing process.

[0052] The printing assembly 7 is disposed in the upper shell 1 and cooperates with the rubber roller 6 to print on the paper 40 .

[0053] The balancing roller 8 is rotatably arranged in the upper shell 1 . The balancing roller 8 is located above the printing component 7 . The carbon ribbon 30 rolls around the balancing roller 8 . The balancing roller 8 is used to eliminate static electricity on the carbon ribbon 30 .

[0054] The printing component 7 includes a thermal mechanism 9 that cooperates with the carbon ribbon 30, paper 40 and rubber roller 6. The thermal mechanism 9 is set on the printing component 7 through an adjusting mechanism. The carbon ribbon 30 is partially wrapped around the lower part of the thermal mechanism 9. The adjusting mechanism can make the vertical force of the thermal mechanism 9 acting on the printing component 7 match the tension of the carbon ribbon 30 according to the different tensions generated by different carbon ribbons 30, so as to adaptively adjust the tension of the carbon ribbon 30 to reduce static electricity; the traditional printing component 7 is equipped with a single spring 71, which can exert a certain force on the carbon ribbon 30, but cannot achieve adaptive adjustment according to different types of carbon ribbon components 3.

[0055] In this embodiment, the printing component 7 includes a print head fixing seat 70, and the print head fixing seat 70 is fixed in the upper shell 1. The adjusting mechanism includes a spring 10, and the spring 10 is locked on the print head fixing seat 70. One end of the upper part of the thermal mechanism 9 is buffer-connected to the print head fixing seat 70 through a spring 71. The bottom of the spring 10 and the upper part of the thermal mechanism 9 are in contact with each other, and the carbon ribbon 30 bypasses the lower part of the thermal mechanism 9. When the carbon ribbon 30 generates different pulling forces acting on the thermal mechanism 9, one end of the thermal mechanism 9 acts on the spring 10 upward or downward, so that the extrusion force of the printing mechanism on the carbon ribbon 30 after being acted upon by the spring 10 is adaptively matched with the pulling force of the carbon ribbon 30.

[0056] In this embodiment, specifically, the thermal mechanism 9 includes a thermal sheet 90 and a thermal sheet fixing seat 91. One end of the upper portion of the thermal sheet fixing seat 91 is elastically abutted against the spring 71, and the upper portion of the other end is elastically abutted against the spring 10. The thermal sheet 90 is fixedly arranged on the thermal sheet fixing seat 91 and corresponds to the carbon ribbon 30 and the rubber roller 6. The thermal sheet 90 corresponds to one end of the paper feeding channel 5 where paper is output. Since different types of carbon ribbons 30 generate different pulling forces during printing, the different pulling forces generated are used to enable the spring 10 to be effectively and automatically adjusted, so that the extrusion force of the thermal mechanism 9 on the carbon ribbon 30 is adaptively adapted to the pulling force of the carbon ribbon 30, thereby reducing the generation of static electricity and reducing the damage to the print head caused by static electricity.

[0057] In this embodiment, a first slope is formed between the paper feeding channel 5 and the horizontal plane, and a second slope is formed between the thermal sheet 90 and the horizontal plane. The first slope is greater than the second slope, thereby reducing the contact area between the thermal sheet 90 and the rubber roller 6. Since the conventional thermal sheet 90 is completely parallel to the paper feeding channel 5, the paper 40 completely adheres to the thermal sheet 90 and rolls on the rubber roller 6 during paper feeding, which generates a lot of static electricity. In this embodiment, the angle of the thermal sheet 90 is changed so that the thermal sheet 90 and the paper feeding channel 5 are not parallel. Therefore, the paper 40 will not completely adhere to the thermal sheet 90, thereby reducing the contact area between the rubber roller 6 and the thermal sheet 90, thereby reducing static electricity.

Since different types of carbon ribbons 30 generate different pulling forces during printing, the different pulling forces generated are used to enable the spring 10 to be effectively and automatically adjusted, so that the extrusion force of the thermal mechanism 9 on the carbon ribbon 30 is adaptively adapted to the pulling force of the carbon ribbon 30, thereby reducing the generation of static electricity and reducing the damage to the print head caused by static electricity.

[0082] In this embodiment, a first slope is formed between the paper feeding channel 5 and the horizontal plane, and a second slope is formed between the thermal sheet 90 and the horizontal plane. The first slope is greater than the second slope, thereby reducing the contact area between the thermal sheet 90 and the rubber roller 6. Since the conventional thermal sheet 90 is completely parallel to the paper feeding channel 5, the paper 40 completely adheres to the thermal sheet 90 and rolls on the rubber roller 6 during paper feeding, which generates a lot of static electricity. In this embodiment, the angle of the thermal sheet 90 is changed so that the thermal sheet 90 and the paper feeding channel 5 are not parallel. Therefore, the paper 40 will not completely adhere to the thermal sheet 90, thereby reducing the contact area between the rubber roller 6 and the thermal sheet 90, thereby reducing static electricity.

[0083] In this embodiment, the print head fixing seat 70 is made of zinc alloy. The print head fixing seat 70 is made of zinc alloy, which is a high-quality conductive material. It can transfer the generated static electricity charge to the mainboard and discharge it quickly, and can also protect the print head.

[0084] In this embodiment, the balancing roller 8 is coated with anti-static rubber on the outside, which can quickly eliminate the static electricity on the carbon ribbon 30 and comprehensively and quickly eliminate the static electricity during the printing process.

[0085] In addition, the present embodiment further includes a thermal film grounding wire A and a print head grounding wire B, wherein the thermal film grounding wire A is connected to the thermal film fixing seat 91, and the print head grounding wire B is connected to the thermal film fixing seat 91 and is arranged on the outside of the upper shell 1, and further includes a rubber roller grounding wire C, wherein the rubber roller grounding wire C is connected to one end of the rubber roller 6 and is arranged on the outside of the lower shell 2. The static electricity generated by the thermal film fixing seat 91 and the rubber roller 6 can be discharged through the thermal film grounding wire A, the print head grounding wire B and the rubber roller grounding wire C and quickly eliminated.
