Description

Technical Field

[0001] The invention belongs to the technical field of printers, and in particular relates to a convenient printer with an anti-paper jam paper feeding passage. Background Art

[0002] As the name suggests, a portable printer has a simple structure and a small size, making it easy to carry around.

[0003] For wide format portable printers, they can adapt to printing on a variety of paper specifications. When a smaller size of printing paper is needed, the width adjuster is required to adjust the paper. Figure 1 As shown, the width adjuster P of the existing convenient printer is arranged on the base Q, and the formed paper feeding channel is linear, and there is a sliding gap K between the bottom of the width adjuster P and the base Q. During the movement of the paper, the paper may be easily stuck in the sliding gap K due to the effect of gravity, thereby causing the defect of paper jam, resulting in printing defects of the convenient printer. Summary of the invention

[0004] The object of the present invention is to provide a convenient printer with an anti-paper jam paper feeding passage to solve the problems raised in the above background technology.

[0005] In view of this, the present invention provides a convenient printer with an anti-paper jam paper feeding passage, comprising:

[0006] Base assembly: the base assembly plays the role of overall support.

[0007] The flip cover assembly is rotatably connected to the base assembly. When in use, the flip cover assembly covers the base assembly. The flip cover assembly can be opened for cleaning and maintenance.

[0008] The paper feed guide is detachably arranged in the base assembly and is located below the flip cover assembly. The paper feed guide mainly serves to guide the paper, and its main structure is related to the smooth paper feeding and paper feeding resistance.

[0009] A paper feed end and a paper discharge end are formed between the base assembly and the flip cover assembly and are located on both sides respectively. In this embodiment, the height of the paper feed end is lower than that of the paper discharge end.

[0010] A paper feeding channel for paper to pass through is formed between the paper feed guide plate and the flap assembly, and the paper feed end and the paper discharge end are respectively located on both sides of the paper feeding channel. When printing, the paper enters from the paper feed end, passes through the paper feeding channel, and is printed and discharged from the paper discharge end.

[0011] A width adjustment component can be movably arranged on the flap component to adjust the width of the adapted paper. The width adjustment component includes a left component and a right component. The left component and the right component are consistent and are symmetrically arranged with respect to each other about the center positioning point on the midline of the flap component. Since the present printer is a wide-format printer, it can adapt to the printing of more specifications of paper. By synchronously sliding the left component and the right component in opposite directions, the distance between them can be changed and adjusted to adapt to more types of paper, thereby improving versatility. Unlike the existing printers, the present solution arranges the width adjustment component on the flap component. Compared with the traditional design of placing it on the base, due to the effect of gravity when the paper is feeding, the paper head will not be stuck in the guide groove of the sliding position of the width adjustment component after it is lowered, thereby effectively avoiding paper jams. When solving paper jams, it can also prevent the paper from warping and bending.

[0012] Among them, the cross-section of the paper feeding channel formed by the paper feed guide plate matched with the left component and the right component between the two ends is in a flag-shaped direction and is not in a straight line direction. The multi-section bending structure formed by the flag-shaped direction limits the paper from entering the sliding gap formed by the left component, the right component and the paper feed guide plate after the paper enters from the paper feed end. The height of the paper feed end is lower than the height of the paper outlet end. The existing paper feeding channel is linear, and there is a sliding gap between the adjuster and the base, which causes the paper to be stuck in the sliding gap along the paper feeding channel when entering, resulting in a paper jam. Since the width adjustment component of this scheme does not have a sliding gap, the flag-shaped paper feeding channel allows the paper head to be pushed straight forward along the paper feeding channel after it drops, and the two ends of the paper are limited between the two inner sides of the left component and the right component and will not be stuck at the bottom thereof.

[0013] A linkage component is arranged on the flip cover component, and the linkage component is linked with the width adjustment component to drive the left component and the right component to move in opposite directions. The linkage component enables the width adjustment components to move synchronously in opposite directions to adapt to more types of paper.

[0014] In the present invention, further, the flag-shaped direction of the paper feeding channel is formed by matching multiple sections of bending surfaces on the upper end surface of the paper feeding guide plate and the lower end surfaces of the left component and the right component.

[0015] In the present invention, further, the upper end surface of the paper feed guide plate sequentially forms a first guide surface, a second guide surface, a third guide surface, a fourth guide surface, a fifth guide surface and a sixth guide surface that are interconnected, wherein the first guide surface, the third guide surface and the fifth guide surface are parallel to each other, the second guide surface and the fourth guide surface are parallel, and the sixth guide surface is a horizontal plane, and the first guide surface and the second guide surface, the third guide surface and the fourth guide surface, and the fourth guide surface and the fifth guide surface are all bent and connected to form, and the height gradually increases in the order of the first guide surface, the second guide surface, the third guide surface, the fourth guide surface, the fifth guide surface and the sixth guide surface. Therefore, when the paper enters, it enters the multiple bending surfaces in sequence and is pushed forward. It will not be pushed forward in a straight line like a traditional printer, but directly enter the sliding gap to cause paper jam.

[0016] In the present invention, further, the first guide surface and the third guide surface are both obliquely arranged, the second guide surface and the fourth guide surface are obliquely arranged, the first guide surface, the third guide surface and the horizontal plane form a starting angle, the second guide surface, the fourth guide surface and the horizontal plane form an ending angle, and the ending angle is greater than the starting angle.

[0017] In the present invention, further, the starting angle is between 0-45°, and the ending angle is between 90-135°. It should be noted that the smaller the starting angle is designed to be, the smaller the resistance of the paper passing through the top surface of the flag-shaped channel is, thereby reducing the resistance to paper feeding and avoiding paper jams and wrinkles.

[0018] In the present invention, further, the base assembly includes a base and a side seat, the side seats are symmetrically arranged on both sides of the base, the base is recessed into a fixing groove, the fixing groove is respectively provided with a first card slot and a second card slot, and the lower part of the paper feed guide is provided with a first clip and a second clip corresponding to the first card slot and the second card slot respectively, and the paper feed guide is respectively fixed by the first clip, the second clip and the first card slot, the second card slot, to achieve quick disassembly and assembly of the paper feed guide.

[0019] In the present invention, further, the flip cover assembly includes an upper cover and an inner cover, the inner cover is installed in the upper cover, the linkage assembly, the left component and the right component are movably arranged between the inner cover and the upper cover, and one end of the outer side of the left component and the right component extends out of the lower part of the inner cover and cooperates on the paper feed guide.

[0020] In the present invention, further, one end of the outer side of the left component and the right component includes an adjustment block, and the inner side of the bottom of the adjustment block is a limiting portion for limiting the paper. Due to the flag-shaped direction of the multi-section bends of the paper feeding channel, the paper will not be stuck in the sliding gap when feeding, and the two sides of the paper are limited between the limiting portions.

[0021] In the present invention, further, the linkage assembly includes a rack formed on the adjustment block and a gear, the gear is meshed with the rack, an external motor drives the gear to rotate, and the gear drives the rack to achieve reverse synchronous movement of the left component and the right component.

[0022] In the present invention, further, the upper cover and the inner cover are convexly formed with protruding columns, the gear is rotatably sleeved on the protruding columns, a limiting plate is formed at the bottom of the upper cover, the rack fits the limiting plate and reciprocates along the length direction of the limiting plate, so that the left component and the right component strictly reciprocate only along the length direction of the limiting plate.

[0036] like Figure 2 As shown, this embodiment provides a convenient printer with an anti-paper jam paper feeding channel, including:

[0037] The base assembly 1 plays a role of overall support.

[0038] The flip cover assembly 2 is rotatably connected to the base assembly 1. When in use, the flip cover assembly 2 covers the base assembly 1. The flip cover assembly 2 can be opened for cleaning and maintenance.

[0039] The paper feed guide 3 is detachably disposed in the base assembly 1 and is located below the flip cover assembly 2. The paper feed guide 3 mainly serves to guide the paper, and its main structure is related to the smooth paper feeding and paper feeding resistance.

[0040] See also Figure 3 and Figure 4 A paper feed end a and a paper discharge end b are formed between the base assembly 1 and the flip cover assembly 2 and are located on both sides respectively. In this embodiment, the height of the paper feed end a is lower than that of the paper discharge end b.

[0041] A paper passage c for paper to pass through is formed between the paper feed guide 3 and the flip cover assembly 2, and the paper feed end a and the paper output end b are respectively located on both sides of the paper passage c. When printing, paper enters from the paper feed end a, passes through the paper passage c, and is printed and output from the paper output end b.

[0042] The width adjustment component 4 is movably arranged on the flap component 2 for adjusting the width of the adapted paper. The width adjustment component 4 includes a left component 4A and a right component 4B. The left component 4A and the right component 4B are consistent and symmetrically arranged with respect to the center positioning point on the center line of the flap component 2. Since the present printer is a wide-format printer, it can adapt to more specifications of paper for printing and use. The distance between the left component 4A and the right component 4B is changed and adjusted by synchronously sliding in opposite directions between the left component 4A and the right component 4B, so as to adapt to more types of paper and improve versatility. Different from the existing printers, the present solution arranges the width adjustment component 4 on the flap component 2. Compared with the traditional design of placing it on the base, due to the effect of gravity when the paper is fed, the paper head will not be stuck in the guide groove of the sliding position of the width adjustment component 4 after it is lowered, thereby avoiding paper jams well. When solving paper jams, it can also prevent the paper from warping and bending.

[0043] The linkage component is arranged on the flap component 2, and the linkage component is linked with the width adjustment component 4, thereby driving the left component 4A and the right component 4B to move in opposite directions. The linkage component enables the width adjustment components 4 to move synchronously in opposite directions to adapt to more types of paper. Example 2

[0044] A convenient printer with an anti-paper jam paper feeding passage, comprising:

[0045] The base assembly 1 plays a role of overall support.

[0046] The flip cover assembly 2 is rotatably connected to the base assembly 1. When in use, the flip cover assembly 2 covers the base assembly 1. The flip cover assembly 2 can be opened for cleaning and maintenance.

[0047] The paper feed guide 3 is detachably disposed in the base assembly 1 and is located below the flip cover assembly 2. The paper feed guide 3 mainly serves to guide the paper, and its main structure is related to the smooth paper feeding and paper feeding resistance.

[0048] A paper feed end a and a paper discharge end b are formed between the base assembly 1 and the flip cover assembly 2 and are located on both sides respectively. In this embodiment, the height of the paper feed end a is lower than that of the paper discharge end a.

[0049] A paper passage c for paper to pass through is formed between the paper feed guide 3 and the flip cover assembly 2, and the paper feed end a and the paper output end b are respectively located on both sides of the paper passage c. When printing, paper enters from the paper feed end a, passes through the paper passage c, and is printed and output from the paper output end b.

[0050] The width adjustment component 4 is movably arranged on the flap component 2 for adjusting the width of the adapted paper. The width adjustment component 4 includes a left component 4A and a right component 4B. The left component 4A and the right component 4B are consistent and symmetrically arranged with respect to the center positioning point on the center line of the flap component 2. Since the present printer is a wide-format printer, it can adapt to more specifications of paper for printing and use. The distance between the left component 4A and the right component 4B is changed and adjusted by synchronously sliding in opposite directions between the left component 4A and the right component 4B, so as to adapt to more types of paper and improve versatility. Different from the existing printers, the present solution arranges the width adjustment component 4 on the flap component 2. Compared with the traditional design of placing it on the base, due to the effect of gravity when the paper is fed, the paper head will not be stuck in the guide groove of the sliding position of the width adjustment component 4 after it is lowered, thereby avoiding paper jams well. When solving paper jams, it can also prevent the paper from warping and bending.

[0051] In this embodiment, the cross-section of the paper feeding channel c formed by the paper feed guide 3 between the two ends of the left component 4A and the right component 4B is in a flag-shaped direction with a non-linear direction. In this embodiment, the flag shape is defined as the connection direction of the upper hypotenuse and the vertical side of a triangular flag. It can be clearly seen from the accompanying drawings that the multi-segment bending structure formed by the flag-shaped direction limits the paper from entering the sliding gap formed by the left component 4A, the right component 4B and the paper feed guide 3 after the paper enters from the paper feed end a. The height of the paper feed end a is lower than the height of the paper outlet end b. The existing paper feeding channel c is linear, and there is a sliding gap between the regulator and the base 10, resulting in the paper entering along the paper feeding channel c and getting stuck in the sliding gap, causing a paper jam. Since the width adjustment component 4 of this scheme does not have a sliding gap, the flag-shaped paper feeding channel c allows the paper head to be pushed straight forward along the paper feeding channel c after it drops, and the two ends of the paper are restricted between the two inner sides of the left component 4A and the right component 4B and will not be stuck at the bottom thereof.

[0052] The linkage component is arranged on the flap component 2, and the linkage component is linked with the width adjustment component 4, thereby driving the left component 4A and the right component 4B to move in opposite directions. The linkage component enables the width adjustment components 4 to move synchronously in opposite directions to adapt to more types of paper.

[0053] The flag-shaped direction of the paper feeding passage c is formed by matching the upper end surface of the paper feeding guide plate 3 with the multiple sections of the bent surfaces of the lower end surfaces of the left component 4A and the right component 4B. Example 3

[0054] A convenient printer with an anti-paper jam paper feeding passage, comprising:

[0055] The base assembly 1 plays a role of overall support.

[0056] The flip cover assembly 2 is rotatably connected to the base assembly 1. When in use, the flip cover assembly 2 covers the base assembly 1. The flip cover assembly 2 can be opened for cleaning and maintenance.

[0057] The paper feed guide 3 is detachably disposed in the base assembly 1 and is located below the flip cover assembly 2. The paper feed guide 3 mainly serves to guide the paper, and its main structure is related to the smooth paper feeding and paper feeding resistance.

[0058] A paper feed end a and a paper discharge end b are formed between the base assembly 1 and the flip cover assembly 2 and are located on both sides respectively. In this embodiment, the height of the paper feed end a is lower than that of the paper discharge end a.

[0059] A paper passage c for paper to pass through is formed between the paper feed guide 3 and the flip cover assembly 2, and the paper feed end a and the paper output end b are respectively located on both sides of the paper passage c. When printing, paper enters from the paper feed end a, passes through the paper passage c, and is printed and output from the paper output end b.

[0060] The width adjustment component 4 is movably arranged on the flap component 2 for adjusting the width of the adapted paper. The width adjustment component 4 includes a left component 4A and a right component 4B. The left component 4A and the right component 4B are consistent and symmetrically arranged with respect to the center positioning point on the center line of the flap component 2. Since the present printer is a wide-format printer, it can adapt to more specifications of paper for printing and use. The distance between the left component 4A and the right component 4B is changed and adjusted by synchronously sliding in opposite directions between the left component 4A and the right component 4B, so as to adapt to more types of paper and improve versatility. Different from the existing printers, the present solution arranges the width adjustment component 4 on the flap component 2. Compared with the traditional design of placing it on the base 10, due to the effect of gravity when the paper is fed, the paper head will not be stuck in the guide groove of the sliding position of the width adjustment component 4 after it is lowered, thereby avoiding paper jams well. When solving paper jams, it can also prevent the paper from warping and bending.

[0061] In this embodiment, Figure 6 The cross section of the paper feeding channel c formed by the paper feed guide 3 between the two ends of the left component 4A and the right component 4B is in a flag-shaped direction with a non-linear direction. The multi-section bending structure formed by the flag-shaped direction limits the paper from entering the sliding gap formed by the left component 4A, the right component 4B and the paper feed guide 3 after the paper enters from the paper feed end a. The height of the paper feed end a is lower than the height of the paper outlet end b. The existing paper feeding channel c is linear, and there is a sliding gap between the adjuster and the base, which causes the paper to be stuck in the sliding gap along the paper feeding channel c when entering, resulting in a paper jam. Since the width adjustment component 4 of this solution does not have a sliding gap, the flag-shaped paper feeding channel c allows the paper head to be pushed straight forward along the paper feeding channel c after it drops, and the two ends of the paper are limited between the two inner sides of the left component 4A and the right component 4B and will not be stuck at the bottom thereof.

[0062] The linkage component is arranged on the flap component 2, and the linkage component is linked with the width adjustment component 4, thereby driving the left component 4A and the right component 4B to move in opposite directions. The linkage component enables the width adjustment components 4 to move synchronously in opposite directions to adapt to more types of paper.

[0063] The flag-shaped direction of the paper feeding passage c is formed by matching the upper end surface of the paper feeding guide plate 3 and the multiple bending surfaces of the lower end surfaces of the left component 4A and the right component.

[0064] In this embodiment, Figure 7 The upper end surface of the paper feed guide 3 sequentially forms a first guide surface 30, a second guide surface 31, a third guide surface 32, a fourth guide surface 33, a fifth guide surface 34 and a sixth guide surface 35 which are connected to each other, wherein the first guide surface 30, the third guide surface 32 and the fifth guide surface 34 are parallel to each other, the second guide surface 31 and the fourth guide surface 33 are parallel, and the sixth guide surface 35 is a horizontal plane. The first guide surface 30 and the second guide surface 31, the third guide surface 32 and the fourth guide surface 33, and the fourth guide surface 33 and the fifth guide surface 34 are all bent and connected to form. The height of the first guide surface 30, the second guide surface 31, the third guide surface 32, the fourth guide surface 33, the fifth guide surface 34 and the sixth guide surface 35 gradually increases in sequence. Therefore, when the paper enters, it enters the multiple bending surfaces in sequence and is pushed forward. It will not be pushed forward in a straight line like a traditional printer and directly enter the sliding gap to cause paper jam.

[0065] In the present invention, further, the first guide surface 30 and the third guide surface 32 are both obliquely arranged, the second guide surface 31 and the fourth guide surface 33 are obliquely arranged, the first guide surface 30, the third guide surface 32 and the horizontal plane form a starting angle A, the second guide surface 31, the fourth guide surface 33 and the horizontal plane form an ending angle B, and the ending angle B is greater than the starting angle A.

[0066] In the present invention, further, the starting angle A is between 0-45°, and the ending angle B is between 90-135°. It should be noted that the smaller the starting angle A is designed to be, the smaller the resistance of the paper passing through the top surface of the flag-shaped channel is, thereby reducing the resistance to paper feeding and avoiding paper jams and wrinkles.

[0067] In the present invention, further, the base assembly 1 includes a base 10 and a side seat 11, the side seat 11 is symmetrically arranged on both sides of the base 10, the base 10 is recessed into a fixing groove 12, the fixing groove 12 is respectively provided with a first card slot 13 and a second card slot 14, and the lower part of the paper feed guide 3 is provided with a first clip 36 and a second clip 37 corresponding to the first card slot 13 and the second card slot 14 respectively, and the paper feed guide 3 is respectively fixed by the first clip 36, the second clip 37 and the first card slot 13, the second card slot 14, so as to realize the quick disassembly and assembly of the paper feed guide 3.

[0068] In the present invention, further, the flip cover assembly 2 includes an upper cover 20 and an inner cover 21, the inner cover 21 is installed in the upper cover 20, the linkage assembly, the left component 4A and the right component 4B are all movably arranged between the inner cover 21 and the upper cover 20, and one end of the outer side of the left component 4A and the right component 4B extends out of the lower part of the inner cover 21 and cooperates on the paper feed guide 3.

[0069] In the present invention, further, as Figure 3 The left component 4A and the right component 4B include an adjustment block 4C at one end outside, and the inner side of the bottom of the adjustment block 4C is a limit portion 4D for limiting the paper. Due to the flag-shaped direction of the multi-section bend of the paper feeding channel c, the paper will not be stuck in the sliding gap during paper feeding, and the two sides of the paper are limited between the limit portions 4D.

[0070] In the present invention, further, the linkage assembly includes a rack 4E formed on the adjustment block 4C, and also includes a gear 4F, the gear 4F is meshed with the rack 4E, an external motor drives the rotation of the gear 4F, and the gear 4F drives the rack 4E to realize the reverse synchronous movement of the left component 4A and the right component 4B.

[0071] In the present invention, further, a protruding column 22 is convexly formed on the upper cover 20 and the inner cover 21, the gear 4F is rotatably sleeved on the protruding column 22, a limiting plate 23 is formed at the bottom of the upper cover 20, and the rack 4E fits the limiting plate 23 and reciprocates along the length direction of the limiting plate 23, so that the left component 4A and the right component 4B strictly reciprocate only along the length direction of the limiting plate 23.
