Figure 7 for Figure 4 A schematic diagram of the cross section along section line VII-VII.
[0028] The printing apparatus 100 of this application includes a body 1, a pressure roller 2, and a printhead device 3. The body 1 is used to accommodate a paper roll 200 to be printed. The paper roll 200 may include, for example, a substrate 201 and a plurality of labels 202, but is not limited thereto. The pressure roller 2 is rotatably disposed on the body 1. The printhead device 3 is disposed on the body 1. The printhead device 3 includes a printhead module 37 that can hold the paper roll 200 to be printed together with the pressure roller 2, and the printhead module 37 is used to print the labels 202.
[0029] The print head device 3 includes: a fixed housing 31, a rotating component 32, a fixing rod 33, two positioning components 34, two pressing components 35, a platform 36, and a print head module 37. The number of positioning components 34 included in the print head device 3 is not limited to two and can be increased or decreased according to actual needs. The number of pressing components 35 included in the print head device 3 is not limited to those shown in the figure. In embodiments where the overall size of the printing device 100 is relatively small, the print head device 3 may also include a single pressing component 35. In embodiments where the overall size of the printing device 100 is relatively large, the print head device 3 may also include three or more pressing components 35.
[0030] The fixed housing 31 is fixed to the body 1 of the printing device 100. The fixed housing 31 is mainly used to house the fixed rod 33 and the pressing assembly 35. The rotating member 32 is rotatably disposed on one side of the fixed housing 31, and the rotating member 32 is located outside the fixed housing 31. One end of the fixed rod 33 is connected to the body 1. The other end of the fixed rod 33 is connected to the rotating member 32. When the rotating member 32 is operated and rotates relative to the fixed housing 31, the fixed rod 33 will be driven to rotate relative to the fixed housing 31.
[0031] Two positioning members 34 are detachably mounted on the fixing rod 33. Each positioning member 34 can be detachably fixed to the fixing rod 33, for example, by screws. By detachably mounting the positioning members 34 on the fixing rod 33, the user can easily and conveniently replace the positioning members 34. Each positioning member 34 includes multiple positioning grooves 341 and multiple protrusions 342, with two positioning grooves 341 on each side of each protrusion 342.
[0032] Platform 36 is rotatably connected to fixed housing 31. A print head module 37 is provided on one side of platform 36. The other side of platform 36 is abutted by pressing component 35. That is, pressing component 35 and print head module 37 are respectively provided on two opposite sides of platform 36.
[0033] Two pressing components 35 are movably mounted on the fixed rod 33, and each pressing component 35 can move relative to the fixed rod 33 along a length direction L1 of the fixed rod 33. The user can directly operate either pressing component 35 by hand to move the pressing component 35 along the length direction.
[0034] Specifically, when a user wants the printing device 100 to print on a larger paper roll 200, the user can manually operate at least one pressing component 35 to increase the distance between the two pressing components 35, and the two pressing components 35 can be positioned approximately adjacent to the two sides of the paper roll 200. Conversely, when a user wants the printing device 100 to print on a smaller paper roll 200, the user can also manually operate at least one pressing component 35 to reduce the distance between the two pressing components 35, and the two pressing components 35 can also be positioned approximately adjacent to the two sides of the paper roll 200.
[0035] In addition, the user can manually adjust the adjustment component 353 of the pressure component 35 to change the force applied by the pressure component 35 to the platform 36, thereby allowing the print head module 37 and the pressure roller 2 to better hold the paper roll 200 to be printed.
[0036] Specifically, when a user wants the printing device 100 to print on a relatively thick roll of paper 200, the user can operate the adjustment component 353 to reduce the force applied to the roll of paper 200 by the pressure component 35. This effectively reduces the probability of paper jams during printing. Conversely, when a user wants the printing device 100 to print on a relatively thin roll of paper 200, the user can operate the adjustment component 353 to increase the force applied to the roll of paper 200 by the pressure component 35, thereby allowing the print head module 37 and the pressure roller 2 to hold the roll of paper 200 securely.
[0037] Please refer to the following: Figures 5 to 9 , Figure 8 This is an exploded view of the pressing component of the print head device of this application. Figure 9 This is a partial perspective cross-sectional view of the pressing component of the printing head device of this application.
[0038] Each pressing component 35 may include a housing 351, a positioning member 352, and an adjusting component 353. The housing 351 is used to house the positioning member 352 and the adjusting component 353. The housing 351 may include a first housing 3511 and a second housing 3512. The first housing 3511 and the second housing 3512 are detachably connected to each other. The positioning member 352 is detachably disposed in a receiving space 3521 of the first housing 3511. The adjusting component 353 is disposed between the first housing 3511 and the second housing 3512.
[0039] The positioning member 352 has an internal accommodating space 3521. The positioning member 352 includes two first through holes 3522 and one second through hole 3523. The two first through holes 3522 are formed on two opposite sidewalls of the positioning member 352, and the second through hole 3523 is formed on the other sidewall of the positioning member 352. Each of the first through holes 3522 and the second through hole 3523 communicates with the accommodating space 3521. The two first through holes 3522 are opposite to each other, and the positioning member 352 is fitted onto the fixing rod 33 through the two first through holes 3522. That is, when the pressing component 35 is installed on the fixing rod 33, the fixing rod 33 passes through the two first through holes 3522.
[0040] The positioning member 352 has a second through hole 3523 on one side, which extends outward to form an elastic arm 3524. The free end of the elastic arm 3524 is located in the second through hole 3523. A positioning protrusion 35241 is formed on one side of the elastic arm 3524, and the positioning protrusion 35241 is located in the accommodating space 3521. When the positioning member 352 is sleeved on the fixing rod 33, the positioning protrusion 35241 is positioned facing the positioning member 34 on the fixing rod 33, and the positioning protrusion 35241 can be correspondingly engaged in any of the positioning grooves 341.
[0041] When the positioning protrusion 35241 engages with one of the positioning grooves 341, the positioning protrusion 35241 and the positioning groove 341 together restrict the range of movement of the pressing component 35 in the length direction L1. At this time, the user must apply sufficient force to make the positioning protrusion 35241 leave the current positioning groove 341, pass over the adjacent protrusion structure 342, and enter another positioning protrusion 35241. This design allows the user to have a good tactile feel when moving the pressing component 35.
[0042] By detachably mounting the positioning member 34 to the fixing rod 33 and detachably mounting the positioning element 352 within the housing 351, the user can easily replace the positioning member 34 and the positioning element 352 as needed. Specifically, after the pressing assembly 35 moves frequently along the fixing rod 33, the positioning protrusion 35241 and the protruding structure 342 of the positioning member 34 may wear out, potentially leading to unstable positioning. Alternatively, the elastic arm 3524 may break or fail to return to its original position correctly. In any of these cases, the user can easily resolve the problem by replacing the positioning element 352 or the positioning member 34.
[0043] In one embodiment, the horizontal distance D between the centers of two adjacent positioning members 34 is between 20 and 90 mm. This design allows the user to adjust the positions of the two pressing components 35, enabling the printing device 100 to be used with paper rolls having a width between 3 and 104 mm. In one practical application, the horizontal distance D may be, for example, 60 mm.
[0044] Please reconsider. Figure 2In one embodiment, the platform 36 may further include a scale 361, which is marked with graduations, and the range of movement of the two pressing components 35 along the length direction L1 is within the measurement range marked by the scale 361. For example, if the scale of the scale 361 is between 0 and 10 centimeters, then the maximum range of movement of either pressing component 35 along the length direction L1 is less than 10 centimeters. Through the design of the scale 361, the user can easily adjust the position of the two pressing components 35 according to the width of the paper roll 200 to be printed.
[0045] like Figure 8 and Figure 9 As shown, each adjustment component 353 may include an operating member 3531, a screw 3532, an auxiliary member 3533, an elastic member 3534, and a pressing member 3535. The operating member 3531 may be, for example, a turntable rotatably disposed between the first housing 3511 and the second housing 3512, with a portion of the turntable protruding from the outer housing 351. One end of the screw 3532 is connected to the turntable. The screw 3532 can rotate with the turntable. The other end of the screw 3532 is screwed into a screw hole 35331 of the auxiliary member 3533. The first housing 3511 and the second housing 3512 can jointly restrict the auxiliary member 3533, preventing it from rotating within the outer housing 351. Thus, when the turntable is operated and rotated, the screw 3532 will drive the auxiliary member 3533 to move along a longitudinal direction L2. The longitudinal direction L2 is not parallel to the length direction L1. One end of the elastic member 3534 is connected to the auxiliary member 3533, and the other end of the elastic member 3534 is connected to the pressing member 3535.
[0046] When the auxiliary component 3533 is driven by the screw 3532 and moves away from the operating component 3531 along the longitudinal direction L2, the auxiliary component 3533 will push against the elastic component 3534, causing the elastic component 3534 to elastically deform, and the elastic component 3534 will push against the pressing component 3535.
[0047] Conversely, when the auxiliary member 3533 is driven by the screw 3532 and moves along the longitudinal direction L2 towards the operating member 3531, one end of the elastic member 3534 will move with the auxiliary member 3533 towards the operating member 3531, and the end of the pressing member 3535 will also move towards the outer shell 351. The first shell 3511 and the second shell 3512 also jointly limit the range of movement of the pressing member 3535 relative to the outer shell 351.
[0048] In practical applications, the first housing 3511 can have multiple markings, and the auxiliary component 3533 can also have an identification protrusion 35332, which protrudes from the housing 351. Through the design of the identification protrusion 35332 and the markings, the user can understand the state of the force applied by the pressing component 35 to the platform 36. For example, the first housing 3511 can have markings of 0, L, and H, which can respectively represent: the force applied by the pressing component 3535 to the platform 36 is close to 0, the pressing component 3535 applies a relatively low force to the platform 36, and the pressing component 3535 applies a relatively high force to the platform 36. The user can then identify which marking corresponds to the protrusion 35332, thus understanding the state of the force applied by the pressing component 35 to the platform 36.
[0049] Please refer to the following: Figure 2 , Figure 4 , Figure 5 and Figure 10 , Figure 10 This is a schematic diagram showing the printhead device of the printing apparatus of this application in its retracted position. Figure 3 and Figure 4 As shown, when the printing device 100 is in the non-retracted state, the two pressing components 35 are set up generally upright, and the pressing parts 3535 of the two pressing components 35 abut against one side of the platform 36.
[0050] When the user operates the rotating component 32, causing it to rotate towards the fixed housing 31 (i.e., the user causes...), Figure 3 (When the rotating part 32 shown rotates counterclockwise), the two pressing components 35 will be driven to rotate towards the fixed housing 31. In this way, the pressing parts 3535 of each pressing component 35 will no longer press against the platform 36.
[0051] When the two pressing components 35 no longer press against one side of the platform 36, the user can rotate the platform 36 away from the pressing roller 2, thereby moving the print head module 37 away from the pressing roller 2. This makes it easier for the user to install the paper roll 200 to be printed, or to deal with paper jams, and also makes it easier for the user to replace the print head module 37 or the roller 2.
[0052] In practical applications, the printing head device 3 may also include multiple auxiliary springs 38. One end of the auxiliary spring 38 is fixed to the fixed housing 31, and the other end of the auxiliary spring 38 is fixed to the platform 36. The platform 36 is rotatably connected to the fixed housing 31. When the pressing member 3535 presses against the platform 36, the auxiliary spring 38 will elastically deform (stretch).
[0053] When the pressing component 35 rotates into the fixed housing 31 along with the rotating component 32, the pressing component 35 will no longer press against the platform 36, and the platform 36 will be driven by the auxiliary spring 38 to rotate relative to the fixed housing 31, thereby causing the printing head module 37 to rotate away from the pressing roller 2 and be exposed.
[0054] In other words, in the example where the platform 36 is connected to multiple auxiliary springs 38, when the user rotates the rotating component 32 relative to the fixed housing 31 so that the pressing component 35 no longer presses against the platform 36, the platform 36 will be driven by the auxiliary springs 38 and automatically rotate towards the fixed housing 31, thereby making the printing module 37 appear in the open state.
[0055] In summary, the printing device and print head assembly of this application, through the design of the fixing rod, positioning component and pressing component, combined with the design of the elastic arm and adjustment component included in the pressing component, allow the user to directly change the position of the pressing component relative to the platform by hand. In this way, the user can easily and simply adjust the position of the pressing component according to the width of the paper roll to be printed, thereby ensuring that the printing device can print well on the paper roll to be printed.
[0056] The embodiments and / or implementation methods described above are merely preferred embodiments and / or implementation methods for implementing the technology of this application, and are not intended to limit the implementation methods of the technology of this application in any way. Any person skilled in the art may make some modifications or alterations to other equivalent embodiments without departing from the scope of the technical means disclosed in this application, but these should still be regarded as the technology or embodiments that are substantially the same as those of this application.
