Description

Technical Field

[0001] This invention relates to the field of electronic weighing instruments, and more particularly to a printing support mechanism. Background Technology

[0002] The basic principle of thermal printing is to convert the data received by the printer into a dot matrix signal to control the heating of the thermal unit. Once the thermal unit contacts the thermal paper, the desired pattern can be printed. The thermal paper can be either non-stick thermal paper or stick thermal paper, and it can be used in offices, factories, warehouses, supermarkets, shopping malls and other scenarios.

[0003] Specifically, a thermal printer mainly includes: a paper roll mounting mechanism, a printing mechanism, and a printing support mechanism. The paper roll mounting mechanism is used to mount and secure the paper roll, the printing mechanism heats the paper to print the desired pattern, and the printing support mechanism assists the printing mechanism in printing the pattern and also supports the paper's movement. In practical applications, accurate paper positioning is crucial to ensure the precision of the printed pattern. Specifically, during the paper's movement within the printer, it is prone to vertical movement, leading to paper misalignment. This misalignment causes printing errors during printing, resulting in poor print quality. Furthermore, if the misalignment persists without correction, the paper will remain in the wrong position within the printer, easily causing paper jams and ultimately printing failures. Additionally, existing printers require a test sheet before replacing paper, leading to paper waste and inefficiency in the long run. Summary of the Invention

[0004] The purpose of this invention is to solve the problem of paper misalignment during the internal transmission of printing paper in the prior art, and the problem that when the printer needs to replace the new printing paper, a test paper must be taken first, which leads to paper waste and low efficiency in the long run.

[0005] To achieve the above objectives, the present invention provides a printing support mechanism disposed within a printing device including a printing mechanism. The printing support mechanism is disposed opposite to the printing mechanism on a base plate and forms a first conveying area for transmitting the printed object, and a second conveying area for transmitting the retrieved object is formed on the side of the printing support mechanism opposite to the printing mechanism.

[0006] The printing support mechanism includes:

[0007] A paper jamming assembly disposed between the first conveying area and the second conveying area, and a base plate that clamps the paper jamming assembly together with the base plate;

[0008] The substrate forms a side plate that abuts against the bottom plate, and the paper jamming assembly includes: an adjusting member longitudinally disposed on the bottom plate and a paper stopper driven by the adjusting member to move axially along the adjusting member;

[0009] The paper stop extends laterally into the first conveying area and the second conveying area respectively to form a first tongue and a second tongue with their bottom surfaces on the same horizontal plane. The axial positions of the first tongue and the second tongue are adjusted synchronously by the adjusting member so that the first tongue and the second tongue, together with the bottom plate, restrict the printing object and the recycling object.

[0010] As a further improvement of the present invention, the paper stop includes: a movable seat, and a first tongue plate and a second tongue plate extending laterally from the movable seat into the first conveying area and the second conveying area, respectively;

[0011] The adjusting component includes: a guide rod longitudinally disposed on the base plate and fitted onto the movable seat, and a driving rod for driving the movable seat to move axially along the guide rod.

[0012] As a further improvement of the present invention, the movable seat has a fourth opening to be sleeved on the outside of the drive rod, the outside of the drive rod is formed with a first thread, and the inside of the fourth opening is formed with a second thread that is adapted to the first thread.

[0013] The drive rod is driven to rotate axially to adjust the axial position of the movable seat.

[0014] As a further improvement of the present invention, the first tongue plate and the movable seat are configured as separate structures, the first tongue plate is sleeved on the outside of the guide rod, and the movable seat forms a first movable ring portion and a second movable ring portion that are sleeved on the outside of the guide rod and clamp the first tongue plate.

[0015] As a further improvement of the present invention, the guide rod is formed in sequence with a fixed shaft segment and a limiting shaft segment in the upward direction along the axial direction of the guide rod, and the first tongue plate is sleeved on the outside of the limiting shaft segment and moves along the axial direction of the limiting shaft segment.

[0016] As a further improvement of the present invention, the side portion of the limiting shaft segment forms a limiting surface that restricts the axial rotation of the first tongue plate;

[0017] The first movable ring and the second movable ring are movably sleeved with the guide rod;

[0018] The guide rod is driven to rotate axially by a linkage mechanism located below the base plate, so as to drive the first tongue plate to move into the first conveying area. When it moves into the first conveying area, the first tongue plate and the base plate together restrict the printing object.

[0019] As a further improvement of the present invention, the adjusting member further includes: a drive input portion disposed on the top of the drive rod to drive the drive rod to rotate axially, the drive input portion being formed on the top of the substrate.

[0020] As a further improvement of the present invention, the linkage mechanism includes: a first link and a second link movably connected to one end of the first link, the end of the first link away from the second link being movably connected to the printing mechanism, and the end of the second link away from the first link being movably connected to the guide rod.

[0021] As a further improvement of the present invention, the end of the first link near the second link extends laterally to form an impact end;

[0022] The printing support mechanism further includes: a trigger controller, and a detection unit disposed between the printing support mechanism and the printing mechanism to detect the printing object being driven within the first conveying area. The trigger controller is activated by the detection unit after being struck by the impact end.

[0023] As a further improvement of the present invention, the outer side of the side plate forms a guide surface that guides the transport of the recyclable object located in the second transport area and partially adheres to the recyclable object.

[0024] As a further improvement of the present invention, the side plate includes:

[0025] The column and the guide plate configured as an integral structure with the column, wherein the guide surface is composed of the surface formed by the outer side of the column and the surface formed by the outer side of the guide plate.

[0026] As a further improvement of the present invention, the column is configured as two and is respectively disposed on both sides of the guide plate, and the column near the adjusting member is provided with a moving groove for the second tongue plate to move axially.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] The first tongue extends into the first conveying area, and together with the base plate, restricts the axial position of the printed object, thus preventing it from shifting up and down during transmission within the first conveying area. Similarly, the second tongue extends into the second conveying area, and together with the base plate, restricts the axial position of the retrieved object, preventing it from shifting up and down during transmission within the second conveying area. By restricting the axial positions of the printed object and the retrieved object in the first and second conveying areas respectively, misalignment of the printed object and / or the retrieved object during transmission within the printing device is prevented. This ensures the accurate determination of the axial position of the printed object when held by the print head and the pressure roller of the print support mechanism, preventing misalignment during printing and ensuring the final printing effect. Furthermore, it avoids paper jams caused by misalignment of the printed object and / or the retrieved object during transmission within the printing device. Meanwhile, when the printing mechanism and the printing support mechanism clamp the printing object, the printing object is detected by the detection unit to prevent waste of the printing object. This solves the problem in the prior art that printers need to test a sheet of paper before replacing it with new paper, which has led to paper waste and low efficiency in the long run.

[0057] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent changes or substitutions in function, method, or structure made by those skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0058] It should be noted that, in this application, "lateral" refers to along... Figure 2 The directions of the X-axis and / or Y-axis shown are shown below. The longitudinal direction refers to the direction along... Figure 2 The direction of the Z-axis is shown.

[0059] Please refer to Figures 1 to 28 As shown, the present invention illustrates a specific embodiment of a print support mechanism 10. This print support mechanism 10 is disposed within a printing apparatus (not shown) that includes a printing mechanism 20, and is used to cooperate with the printing mechanism 20 to fix the printed object, and to transport the recycled object to a waste paper recycling mechanism 30.

[0060] Specifically, the printing device includes: a paper roll mounting mechanism 40, a printing mechanism 20, a printing support mechanism 10, a waste paper recycling mechanism 30, and a control mechanism 50, all disposed on a base plate 60; wherein the printing mechanism 20 and the printing support mechanism 10 are arranged opposite to each other, and a first conveying area A for transmitting the printed object is formed between the printing mechanism 20 and the printing support mechanism 10, and a second conveying area B for transmitting the recycled object is formed on the side of the printing support mechanism 10 opposite to the printing mechanism 20. Figure 3 and Figure 26 As shown, the paper roll mounting mechanism 40 is not driven by a power mechanism (e.g., a first drive motor 51). Multiple meshing gears transmit the power of the first drive motor 51 to the pressure roller 11 to drive the pressure roller 11 to rotate. Multiple meshing gears also transmit the power of the second drive motor 52 to the waste paper recycling mechanism 30 to drive the waste paper recycling mechanism 30 to rotate and perform the winding operation of the recycling object (e.g., the base paper contained in a thermal paper).

[0061] The printing object is wound to form a core with cutouts (hereinafter referred to as "the rolled printing object"). The rolled printing object is fitted onto the paper roll mounting mechanism 40. The printing object passes through the first conveying area A formed between the printing mechanism 20 and the printing support mechanism 10. The printing mechanism 20 and the printing support mechanism 10 hold the printing object and push it towards the exit C formed at the intersection of the first conveying area A and the second conveying area B during the continuous printing operation performed by the printing mechanism 20.

[0062] Optional, refer to Figure 4 As shown, in the example where the printing object is thermal paper, after printing is completed, a recyclable object is formed. The recyclable object passes through the second transport area B formed by the printing support mechanism 10 and the printing mechanism 20 (see direction C80), and is rolled up and installed in the waste paper recycling mechanism 30, thereby completing the entire operation process of the printing device. The printing object is kept in a taut state in both the first transport area A and the recyclable object in the second transport area B.

[0063] Optional, refer to Figure 27 As shown, in the example where the printing object is non-stick thermal paper, after printing is completed, the non-stick thermal paper is directly output from the exit C formed at the intersection of the first transport area A and the second transport area B, without having to pass through the second transport area B (as shown in direction C90).

[0064] In this application, the entire operation process is controlled by the control mechanism 50 included in the printing device, and specifically by the first drive motor 51, the second drive motor 52 and the circuit board 53 and other components provided in the control mechanism 50, so as to realize continuous printing operation.

[0065] It should be noted that in this application, the printing object refers to the object to which a printing operation needs to be performed by the printing mechanism 20, such as thermal paper; the recycling object refers to the object remaining after the target object (i.e., the thermal paper) is peeled off after printing, such as the backing paper. For example, if self-adhesive labels are printed by the printing device, the self-adhesive label before printing is the printing object, and the backing paper left after peeling off the label after printing is the recycling object. Specifically, see... Figure 4 and Figure 27 As shown, the printing objects referred to in this embodiment include thermal paper 200 with a backing and thermal paper 300 without a backing. When thermal paper 200 with a backing is used as the printing object, the recycled object is the backing paper (or the backing paper remaining after peeling off the thermal paper with adhesive backing, and the border area with adhesive backing remaining on the backing paper, not shown in this embodiment); when thermal paper 300 without a backing is used, the recycled object is none, and in this case, the paper without a backing passes through the second conveying area B. (See reference...) Figure 4As shown, after the thermal paper 200 completes the printing job, it forms an output label 201; (Refer to...) Figure 27 As shown, after the non-stick thermal paper 300 completes the printing job, it forms output label 2 301.

[0066] Specifically, participants Figure 2 and Figure 3 As shown, the printing mechanism 20 includes: a print head 21 and a supporting post 22 arranged from the outside to the inside of the first conveying area A, and a drive post 23 arranged on the side of the print head 21 facing away from the printing support mechanism 10. The drive post 23 rotates axially around its central axis C3 to push the print head 21 and the pressure roller 11 to switch between a mating state and a separating state. The drive post 23 includes: a longitudinally arranged fixed post 231, a drive member 232 sleeved on the outside of the fixed post 231 and rotating around the central axis C3 of the fixed post 231, and a printing support 233 for supporting the fixed post 231; wherein, the bottom of the fixed post 231 extends into the base plate 60 and the auxiliary plate 61 in sequence, and the fixed post 231, the base plate 60 and the auxiliary plate 61 are fixedly assembled by a locking member 136. The driving component 232 forms a driving part 234 on the side of the fixed post 231 near the print head 21, and the bottom of the driving part 234 extends downward to form a driving head 235 that penetrates the auxiliary plate 61. The auxiliary plate 61 has an arc-shaped hole 611 for the driving head 235 to slide. The printing support 233 forms a support post 236 on the side of the fixed post 231 away from the print head 21. The bottom of the support post 236 extends into the base plate 60 and the auxiliary plate 61 in sequence, and the support post 236, the base plate 60 and the auxiliary plate 61 are fixedly assembled by a locking component 136. Similarly, the top of the abutment post 22 is fixedly assembled with the printing support 233, and the bottom end of the abutment post 22 extends into the base plate 60. The abutment post 22 and the base plate 60 are fixedly assembled by a locking component 136. A fixed seat 63 protrudes from the side of the auxiliary plate 61 near the support column 236, and a first connecting rod 81 is sleeved on the outside of the drive head 235. The printing mechanism 20 also includes an elastic element 24 disposed at the bottom of the auxiliary plate 61, with one end of the elastic element 24 sleeved on the fixed seat 63 and the other end sleeved on the first connecting rod 81.

[0067] By driving the driving member 232 to rotate about the central axis C3 in the direction C31, the driving part 234 is driven to rotate about the central axis C3 in the direction C31, so that the driving head 235 slides along the contour of the arc-shaped hole 611, and the driving part 235 pushes the print head 21 to move in the direction close to the pressure roller 11 until the print head 21 is in a fitting state with the pressure roller 11. Under the action of the elastic member 24 and the arc-shaped hole 611, the print head 21 and the pressure roller 11 remain in the fitting state unchanged, thereby realizing the fitting of the print head 21 and the pressure roller 11 to clamp the printing object, and based on this, the printing operation on the printing object is realized to prevent the problem of printing disorder and finally ensure the printing effect. Similarly, by driving the driving member 232 to rotate about the central axis C3 in the direction C32, the driving part 234 is driven to rotate about the central axis C3 in the direction C

[0068] Refer to Figure 1 , Figure 2 and Figure 26As shown, the waste paper recycling mechanism 30 includes: a U-shaped and elastic recycling wing 31, a main shaft (not shown), and a recycling rack 33 for winding the recycling object; among them, the main shaft is formed at the bottom of the recycling rack 33 and is driven by a second drive motor 52. A bottom hole (not shown) for the main shaft to pass through is provided on the bottom plate of the recycling wing 31, and card slots 311 are opened on the side parts of the two side plates included in the recycling wing 31. Only one card slot 311 can be provided, or multiple card slots 311 can be provided. The recycling object can be first clamped in the card slot 311 to fix the recycling object. For the convenience of operation, pull rings 312 are opened on the side plates included in the recycling wing 31. Only one pull ring 312 can be provided, or multiple pull rings 312 can be provided. This embodiment does not make specific limitations on this. The main shaft extends downward from the bottom of the recycling rack 33, sequentially passes through the bottom hole and the bottom plate 60 opened by the recycling rack 33, and the bottom of the main shaft is connected to a control motor (not shown) included in the control mechanism 50 to be driven by the control motor. At the same time, when the main shaft passes through the bottom hole opened by the recycling rack 33, it is fixedly connected to the recycling rack 33. By placing the recycling object into the card slot 311 opened by the recycling wing 31 and driving the main shaft to rotate around its central axis C4 by the control motor, the entire recycling mechanism 30 is driven to rotate, so as to clamp the recycling object, thereby realizing the transmission of the recycling object to the waste paper recycling mechanism 30.

[0069] Refer Figures 4 to 6As shown, the printing support mechanism 10 includes: a pressure roller 11 and a guide roller 12 arranged from the outside to the inside of the first conveying area A, and a support member 13 disposed on the top of the pressure roller 11 and the guide roller 12. The support member 13 includes: a base plate 131 that, together with the base plate 60, clamps the pressure roller 11 and the guide roller 12, and a pressure plate 132 that is movably separated from the base plate 131. The base plate 131 can be made by casting, stamping, or 3D printing. The base plate 131 forms a side plate 1311 that abuts against the base plate 60, and a notch 1312 is formed laterally on the edge of the base plate 131. The pressure plate 132 and the base plate 60 together restrict the pressure roller 11 to a preset position formed on the base plate 131. After the pressure plate 132 is removed, the pressure roller 11 moves out from the notch 1312. The pressure roller 11 is assembled into a preset position formed by the base plate 131 and the bottom plate 60 clamping the pressure roller 11, and is restricted to the preset position by the pressure plate 132 disposed on the top of the base plate 131 and the bottom plate 60 disposed on the bottom of the base plate 131. When it is necessary to remove the pressure roller 11, the pressure plate 132 is removed from the top of the base plate 131, and the pressure roller 11 is moved out through the notch 1312 formed laterally through the edge of the base plate 131, thereby realizing the removal of the pressure roller 11. During the removal process, only the pressure plate 132 needs to be removed, and other components included in the printing support mechanism 10 (such as the guide roller 12 and the paper jam assembly 14) do not need to be removed to remove the pressure roller 11, and the removal process is simple. At the same time, when it is necessary to install the pressure roller 11, the pressure roller 11 is moved out through the notch 1312 formed laterally through the edge of the base plate 131. The first fixing hole 1314 is inserted laterally at 12 locations to assemble the pressure roller 11 into a preset position, and the pressure plate 132 is assembled onto the top of the substrate 131, thereby realizing the installation of the pressure roller 11. During the installation process, only the pressure roller 11 and the pressure plate 132 need to be operated accordingly, while the substrate 131 remains stationary. This eliminates the need for the steps of aligning multiple holes simultaneously as required in the prior art, making the installation process simple. This solves the problem that the existing printing support mechanism has a complicated disassembly process for the pressure roller 11 due to its structural design, and that there are many inconveniences in disassembling and assembling the pressure roller 11.

[0070] In one implementation, the reference Figure 4 , Figure 6 and Figure 7As shown in the figure, the top end of the pressure roller 11 axially extends upward to form a first journal section 111 penetrating through the substrate 131. The substrate 131 is provided with a first fixing hole 1314 for the first journal section 111 to penetrate through, and the first fixing hole 1314 is communicated with the notch 1312. Specifically, the substrate 131 includes a substrate body 1313 horizontally arranged on the tops of the pressure roller 11 and the guide roller 12, and a side plate 1311 longitudinally arranged on one side of the substrate body 1313 close to the first transmission area B. The substrate body 1313 is arranged on the top of the side plate 1311, and the first fixing hole 1314 is opened on the substrate body 1313. In this application, the substrate body 1313 and the side plate 1311 can be configured as an integral structure. The bottom plate 60 is continuously penetrated from bottom to top by a locking member 136 (for example, a screw, etc.) and extends into the bottom of the side plate 1311 to form a detachable connection. The side plate 1311 reliably connects the parallel substrate 131 and the bottom plate 60. Thus, the detachable connection between the substrate 131 and the bottom plate 60 is achieved, and the stability of the assembly of the substrate 131 is ensured thereby.

[0071] As shown in the figure Figure 7 and Figure 8 As shown in the figure, the pressure roller 11 includes a pressure roller body 112, a first journal section 111 arranged on the top of the pressure roller 11, and a second journal section 113 extending from the bottom of the pressure roller 11 and having a reduced diameter; wherein, the first journal section 111, the pressure roller body 112, and the second journal section 113 can be configured as an integral structure or a split structure, and are fixedly assembled in sequence. The bottom plate 60 is provided with a first opening 64 only for the second journal section 113 to penetrate through. The first journal section 111 and the second journal section 113 respectively penetrate through the first fixing hole 1314 opened on the substrate 131 and the first opening 64 opened on the bottom plate 60, so that the substrate 131 and the bottom plate 60 jointly clamp the pressure roller 11. In this application, the preset position is the position formed when the pressure roller 11 is jointly clamped by the substrate 131 and the bottom plate 60 when the first journal section 111 and the second journal section 113 respectively penetrate through the first fixing hole 1314 and the first opening 64. Since the second journal section 113 has a reduced diameter relative to the pressure roller body 112, when the pressure roller 11 is assembled, the bottom surface of the pressure roller body 112 can be abutted against the top surface of the bottom plate 60, thereby preventing the pressure roller 11 from slipping off from the first opening 64.

[0072] In one embodiment, as shown in the figure Figure 7 As shown in the figure, the first journal section 111 sequentially forms a first shaft section 1111 with a reduced diameter and capable of moving out from the notch 1312 and a second shaft section 1112 penetrating through the first fixing hole 1314 along the axially upward extension direction of the pressure roller 11; wherein, the axially upward extension direction of the pressure roller 11 is Figure 5The diagram shows the upward extension direction along the central axis C1 of the pressure roller 11. The opening width of the notch 1312 is smaller than the diameter of the first fixing hole 1314, thus the lateral width of the first shaft segment 1111 is smaller than the lateral width of the second shaft segment 1112. Based on this, the pressure roller 11 moves into the notch 1312 through the first shaft segment 1111, forming a clamping action between the base plate 131 and the base plate 60. When the base plate 131 and the base plate 60 clamp the pressure roller 11, since the lateral width of the first shaft segment 1111 is smaller than the lateral width of the second shaft segment 1112, the second shaft segment 1112 is accommodated in the first fixing hole 1314 and cannot move out of the notch 1312, thereby effectively restricting the lateral position of the pressure roller 11 and preventing the pressure roller 11 from falling out of the notch 1312 during assembly.

[0073] Specifically, when the pressure roller 11 needs to be installed, the pressure roller 11 moves in through the notch 1312, that is, the first shaft segment 1111 moves into the first fixing hole 1314 through the notch 1312 and moves downward along the axial direction of the pressure roller 11 to ensure that the second shaft segment 1112 passes through the first fixing hole 1314 and the second journal segment 113 passes through the first opening 64, thereby assembling the pressure roller 11 in a preset position. After assembly, the pressure plate 132 is assembled on the top of the base plate 131 to hold the pressure roller 11 against the preset position. That is, the pressure roller 11 is fixedly installed on the substrate 131 by the pressure plate 132 and the base plate 60 together restricting the pressure roller 11 to a preset position. When it is necessary to disassemble the pressure roller 11, the pressure plate 132 assembled on the top of the substrate 131 is removed, and the pressure roller 11 moves upward along its axial direction and moves to the corresponding position of the first shaft segment 1111 at the notch 1312. The pressure roller 11 is removed by the first shaft segment 1111 moving out of the notch 1312, thereby disassembling the pressure roller 11. In the entire disassembly and assembly process of the pressure roller 11, it is only necessary to perform the corresponding operation on the pressure roller 11 through the notch 1312 to achieve the disassembly and assembly of the pressure roller 11, without the need to disassemble or assemble the substrate 131 or other components. This makes the disassembly and assembly process of the pressure roller 11 very simple, thereby solving the technical problem that the disassembly steps of the pressure roller 11 contained in the existing printing support mechanism are cumbersome and the disassembly and assembly of the pressure roller 11 is inconvenient.

[0074] In one implementation, the reference Figure 5 , Figure 7 and Figure 9As shown, the support member 13 further includes: a support ring 133 sleeved outside the second shaft segment 1112 and penetrating the first fixing hole 1314, and the support ring 133 is accommodated in the first fixing hole 1314 opened in the substrate 131. The pressure roller 11 further includes: a rubber ring (not shown) sleeved on the second journal segment 113 and disposed on the top of the bottom plate 60. Through the support ring 133 sleeved on the first journal segment 111 and the rubber ring sleeved on the second journal segment 113, the axial rotation of the pressure roller 11 between the substrate 131 and the bottom plate 60 (i.e., rotating around the central axis C1) is ensured, and thus the transmission of the pressure roller 11 to the printing object can be effectively ensured.

[0075] As shown Figure 10 For the fixing method of the support ring 133, in the present application, the support ring 133 can be fixed to the substrate body 1313. For example, taking Figure 10 the shown support ring 133’ as an example, the support ring 133’ includes: a support ring body 1331’ sleeved outside the second shaft segment 1112 and a fixing ring 1332’ extending horizontally from the top end of the support ring body 1331’. When the support ring 133’ is assembled, the support ring body 1331’ is sleeved outside the second shaft segment 1112, and the bottom surface of the fixing ring 1331’ is in contact with the top surface of the substrate body 1313 to hold the support ring 133’ by the substrate 131; at the same time, the pressing plate 132 is assembled on the top of the substrate body 1313 to clamp the fixing ring 1332’ jointly by the pressing plate 132 and the substrate body 1313, thereby realizing the stable installation of the support ring 133.

[0076] In an embodiment, as shown Figure 7 、 Figure 10 and Figure 11 shown, the second shaft segment 1112 sequentially forms a first abutting segment 1113 for abutting the support ring 133 and a first diameter-reduced segment 1114 for the support ring 133 to be sleeved along the upward extension direction of the axial direction of the pressure roller 11. The support ring 133 is sleeved outside the first diameter-reduced segment 1114, and the top surface of the first abutting segment 1113 is in contact with the bottom surface of the support ring 133 to abut the support ring 133 through the first abutting segment 1113, thereby further realizing the stable installation of the support ring 133.

[0077] In an embodiment, as shown Figure 12As shown, the pressure plate 132 has a fixing opening 1321, and the second shaft segment 1112 passes through the first fixing hole 1314 and is accommodated in the fixing opening 1321. At this time, the second shaft segment 1112 can be configured not to pass through the fixing opening 1321 (i.e., accommodated in the fixing opening 1321). Thus, not only can the fixing opening 1321 of the pressure plate 132 be used to effectively position the pressure plate 132 during installation, but the pressure plate 132 can also apply axial downward pressure to the support ring 133 so that the pressure plate 132 and the first abutting segment 1113 can jointly clamp the support ring 133, thereby further achieving stable installation of the support ring 133.

[0078] In one implementation, the reference Figure 9 and Figure 12 As shown, the fixing port 1321 allows the second shaft section 1112 to pass through. The support ring 133 extends upward along the axial direction of the pressure roller 11, forming a second abutting section 1333 that abuts against the pressure plate 132 and a second radially narrowed section 1334 that passes through the fixing port 1321. The second abutting section 1333 is accommodated in the first fixing hole 1314, and the top surface of the second abutting section 1333 is in contact with the top surface of the pressure plate 132. The second radially narrowed section 1334 may or may not pass through the second shaft section 1112, thereby abutting the support ring 133 through the second abutting section 1333, thus further achieving stable installation of the support ring 133.

[0079] In one implementation, the reference Figure 8 , Figure 13 and Figure 14As shown, the guide roller 12 includes a guide roller shaft 121 held by the base plate 131 and the base plate 60, and a roller body 122 movably sleeved on the outside of the guide roller shaft 121. A first fixing post (not shown) extending into the guide roller shaft 121 is formed at the bottom of the base plate 131. A fixing hole 1211 for accommodating the first fixing post is formed at the top of the guide roller shaft 121. A second fixing post 1212 extending into the base plate 60 and tapering in diameter is formed at the bottom of the guide roller shaft 121. A second opening 62 is provided in the base plate 60 for the second fixing post 1212 to pass through. Alternatively, the second fixing post 1212 may also partially extend into a blind hole (not shown) provided in the base plate 60. The guide roller shaft 121 is accommodated by a first fixing post in a fixing hole 1211 and a second fixing post 1212 passes through a second opening 62, so that the guide roller shaft 121 is clamped by the base plate 60 and the substrate 131, and the guide roller 121 can rotate axially between the base plate 60 and the substrate 131 via the guide roller shaft 121. The roller body 122 is sleeved on the outside of the guide roller shaft 121 and can rotate about the central axis C2 of the roller body 122 to guide the transmission of the printed object in the first conveying area A. In this application, the guide roller shaft 121 and the first fixing post can be configured as an integral structure (i.e., the guide roller shaft 121 and the substrate 131 can be configured as an integral structure), and / or, the second fixing post 1212 included in the guide roller 12 and the base plate 60 can be configured as an integral structure.

[0080] In this application, a roll-shaped printing object is mounted on a paper roll mounting mechanism 40. The printing object passes through a first conveying area A formed between the printing mechanism 20 and the printing support mechanism 10. Specifically, the guide roller 12 and the abutment post 22 are arranged opposite each other, and the print head 21 and the pressure roller 11 are arranged opposite each other. The printing object first passes through the guide roller 12 and the abutment post 22, and then passes through the print head 21 and the pressure roller 11. That is, the first conveying area A is jointly defined by the area between the opposing guide roller 12 and the abutment post 22 and the area between the opposing print head 21 and the pressure roller 11. After the object to be printed passes through the print head 21 and the pressure roller 11, the drive unit 234 rotates around the central axis C3 in direction C31 to push the print head 21 towards the pressure roller 11 until the print head 21 and the pressure roller 11 are in contact, so that the print head 21 and the pressure roller 11 hold the object to be printed, so that the print head 21 can print the object (or, the print head 21 presses the object to the pressure roller 11 so that the print head 21 can print the object). After printing is completed, the object to be printed is folded back from the paper peeling member 70 located at the inner end of the first conveying area A to the second conveying area B through the folding plate 71. The folding plate 71 separates the object to peel off the target object from the printed object and leaves the recyclable object. The recyclable object passes through the second conveying area B and is rolled up and assembled in the waste paper recycling mechanism 30, thereby realizing the entire printing process in the printing device.

[0081] In one implementation, the reference Figure 6 and Figure 12 As shown, the substrate body 1313 is provided with a first stepped portion 1315 that clamps the pressure roller 11 with the base plate 60 and a second stepped portion 1316 that clamps the guide roller 12 with the base plate 60, arranged sequentially from the outside to the inside of the first conveying area A. The first fixing hole 1314 and the notch 1312 are both opened in the first stepped portion 1315. The pressure plate 132 is only assembled on the top of the first stepped portion 1315. The side of the second stepped portion 1316 near the first stepped portion 1315 forms a lateral abutment surface 13161 for the pressure plate 132. When the pressure plate 132 is assembled on the top of the first stepped portion 1315, the side 1323 of the pressure plate 132 is in contact with the abutment surface 13161 of the second stepped portion 1316 to form a lateral abutment surface for the pressure plate 132, thereby limiting the lateral position of the pressure plate 132. It can also play a pre-fixing role for the pressure plate 132 when it is assembled. To better facilitate the determination of the assembly position during the assembly of the pressure plate 132, at least one fixing point 13151 protrudes from the top of the first step portion 1315. The pressure plate 132 has a fixing hole 1322 through which the fixing point 13151 partially or completely passes. The fixing point 13151 passing through the fixing hole 1322 further pre-fixes the pressure plate 132, thus facilitating the determination of the assembly position of the pressure plate 132. Regarding the connection between the first step portion 1315 and the pressure plate 132, at least one locking member 135 can continuously pass through both the pressure plate 132 and the first step portion 1315 to achieve a detachable connection. Of course, any other connection method can be used to facilitate the assembly and disassembly of the pressure roller 11.

[0082] In one implementation, the reference Figure 15 and Figure 16 As shown, the printing support mechanism 10 further includes a paper-peeling member 70 disposed outside the pressure roller 11 and parallel to the pressure roller 11, the paper-peeling member 70 being perpendicular to the base plate 60. The paper-peeling member 70 includes: a folding plate 71 located at the inner to outer end of the first conveying area A to separate the printing object, and a fixing plate 72 extending inward from the top of the folding plate 71 to form a clamping plate 131 and the pressure roller 11 and sleeved on the outside of the support ring 133. Figure 4As shown, the folding plate 71 is formed at the exit C formed at the intersection of the first conveying area A and the second conveying area B. The folding plate 71 extends outward from its inner end to form a strip-shaped convex plate 74. The printed object is constantly tensioned by the convex plate 74 as it continuously passes through the first conveying area A and the second conveying area B, minimizing contact between the printed object / recycled object and the two bent surfaces of the folding plate 71. The folding plate 71 and the fixing plate 72 are configured as an integral structure. The fixing plate 72 has a hole 721 through which the support ring 133 passes. The fixing plate 72 is sleeved on the outside of the support ring 133 through the hole 721. To ensure the stability of the fixing plate 72 installation, the fixing plate 72 is only positioned at the top of the first step portion 1315, so that the second step portion 1316 laterally supports the fixing plate 72, and also achieves pre-fixation of the fixing plate 72.

[0083] Specifically, refer to Figure 28 As shown, the folding plate 71 forms a first bending surface 711 and a second bending surface 712 on one side of the first conveying area A and the other side of the second conveying area B, respectively. When the printing object is a base thermal paper 200, both the label and the backing paper contained in the base thermal paper 200 are in contact with the first bending surface 711. After the base thermal paper 200 is printed, the label 201 formed is held by the convex plate 74 and automatically separates from the backing paper. Only the backing paper (i.e., the lower concept of the recycled object) folds back from the convex plate 74 and contacts the second bending surface 712 to fold back to the second conveying area B. When the printing object is a baseless thermal paper 300, the baseless thermal paper 300 is in contact with the first bending surface 711, and the label 301 formed after the baseless thermal paper 300 is printed is output from the exit C and does not fold back from the convex plate 74 to the second conveying area B. That is, the baseless paper passes through the second conveying area B. In addition, the protruding plate 74 forms a gap with the printing mechanism 20.

[0084] The printing device further includes: an auxiliary plate 61 disposed at the bottom of the bottom plate 60 and at the outermost end of the first conveying area A from the inside outwards, and through at least one locking member 136, and it can be realized that the auxiliary plate 61 and the bottom plate 60 are detachably connected by continuously penetrating the auxiliary plate 61 and the bottom plate 60 through only one locking member 136. A fixing foot 73 extends downward from the bottom of the folding plate 71, and the auxiliary plate 61 is provided with a fixing foot hole 611 for accommodating the fixing foot 73. The fixing foot 73 is accommodated in the fixing foot hole 611 so that the bottom of the paper peeling member 70 is abutted by the auxiliary plate 61. The fixing plate 72 is sleeved outside the supporting ring 133 through the hole 721 and is disposed on the top of the first step portion 1315. The pressing plate 132 is disposed on the top of the fixing plate 72 so that the pressing plate 132 is embedded into the first step portion 1315, and the fixing plate 72 is clamped jointly by the pressing plate 132 and the first step portion 1315, and a locking member 135 continuously penetrates the pressing plate 132, the fixing plate 72 and the first step portion 1315 and is screwed into the internally threaded blind hole 13162 opened on the first step portion 1315. Thus, the detachable connection of the pressing plate 132, the paper peeling member 70 and the substrate 131 is realized, and further the stable assembly of the paper peeling member 70 is realized. It should be noted that in the present application, the folding plate 71 included in the paper peeling member 70 is used to separate the printing object and is specifically applied to the printing of base-coated thermal paper, that is, to realize the separation of the label and the base paper in the base-coated thermal paper. When printing on uncoated thermal paper, the configuration of the paper peeling member 70 can be omitted.

[0085] Refer Figure 5 to Figure 6As shown, the side plate 1311 includes a column 13111 and a guide plate 13112 integrally configured with the column 13111. Two columns 13111 are configured and respectively disposed on both sides of the guide plate 13112. A mounting hole (not shown) is provided at the bottom of the column 13111. A locking member 136 passes through the base plate 60 and is screwed to the mounting hole (i.e., screwed to the column 13111) to achieve a detachable connection between the base plate 131 and the base plate 60. Simultaneously, a guide surface is formed on the outer side of the side plate 1311 to guide the transfer of the reclaimed object located in the second transfer area B and to partially conform to the reclaimed object. This guide surface is jointly composed of the surface formed by the outer side of the column 13111 and the surface formed by the outer side of the guide plate 13112. In this application, the surface formed on the outer side of the column 13111 and the surface formed on the outer side of the guide plate 13112 are configured to be on the same plane and fully conform to the reclaimed object in an arc shape, so as to better guide the reclaimed object in the transmission within the second transmission area B; or, the surface formed on the outer side of the column 13111 and the surface formed on the outer side of the guide plate 13112 are configured not to be on the same plane, that is, the column 13111 is convex outward relative to the guide plate 13112, so that the reclaimed object only conforms to the surface formed on the outer side of the column 13111 (that is, the guide surface partially conforms to the reclaimed object), so as to form an adjustment space (not indicated) for the reclaimed object to be adjusted laterally within the second transmission area B.

[0086] Specifically, in combination Figure 6 and Figure 18 As shown, two pillars 13111 are configured as an example. The two pillars 13111 are respectively disposed on both sides of the guide plate 13112, and a moving groove 13114 for axial movement of the second tongue plate 1422 is formed on the main body 13111 near the adjusting member 141. The second tongue plate 1422 extends out of the moving groove 13114 and, together with the base plate 60, restricts the retrievable object. The axial position of the second tongue plate 1422 within the moving groove 13114 is adjusted by the adjusting member 141 to further limit the adjustment range of the axial position of the second tongue plate 1422, thereby ensuring the stability of the axial position adjustment of the second tongue plate 1422.

[0087] In this embodiment, by using one locking member 135 and 136 at the top and bottom respectively, the pressure roller 11, guide roller 12 and paper card assembly of the substrate 131 can be fixed in a vertical position relative to the base plate 60 and the substrate 131. This not only simplifies the structure and reduces the number of parts, but also reduces the cumbersomeness of disassembly and assembly.

[0088] In one implementation, the reference Figure 17 and Figure 18As shown, the printing support mechanism 10 further includes a paper jamming assembly 14 disposed between the first conveying area A and the second conveying area B. The paper jamming assembly 14 is held by the base plate 60 and the base plate 131. The paper jamming assembly 14 includes an adjusting member 141 longitudinally disposed on the base plate 60 and a paper stop member 142 driven by the adjusting member 141 to move axially along the adjusting member 141. The paper stop member 142 extends laterally into the first conveying area A and the second conveying area B respectively to form a first tongue plate 1421 and a second tongue plate 1422 with their bottom surfaces on the same horizontal plane. The axial positions of the first tongue plate 1421 and the second tongue plate 1422 are adjusted synchronously by the adjusting member 141 so that the first tongue plate 1421 and the second tongue plate 1422, together with the base plate 60, restrict the printing object and the recycling object. The first tongue 1421 extends into the first conveying area A, and together with the base plate 60, restricts the axial position of the printed object, thereby preventing the printed object from moving up and down during transmission within the first conveying area A. Similarly, the second tongue 1422 extends into the second conveying area B, and together with the base plate 60, restricts the axial position of the retrieved object, thereby preventing the retrieved object from moving up and down during transmission within the second conveying area B. Thus, by restricting the axial positions of the printed object and the retrieved object in the first conveying area A and the second conveying area B respectively, it prevents the printed object and / or the retrieved object from shifting during transmission within the printing device. This ensures the determination of the axial position of the printed object when the print head 21 included in the printing mechanism 20 and the pressure roller 11 included in the printing support mechanism 10 clamp the printed object, preventing misprinting and ensuring the final printing effect of the printing device. At the same time, it also avoids paper jams caused by the offset of the printed object and / or the retrieved object during transmission within the printing device. In addition, the bottom surface of the first tongue plate 1421 and the bottom surface of the second tongue plate 1422 are located on the same horizontal plane to ensure that the width of the printing object transmission restricted by the first tongue plate 1421 and the base plate 60 is the same as the width of the recycling object transmission restricted by the second tongue plate 1422 and the base plate 60.

[0089] In one implementation, the reference Figure 18As shown, the paper stop 142 includes: a movable seat 1423, and a first tongue plate 1421 and a second tongue plate 1422 extending laterally from the movable seat 1423 into the first conveying area A and the second conveying area B, respectively. The adjusting member 141 includes: a guide rod 1411 longitudinally disposed on the base plate 60 and fitted onto the movable seat 1423, and a driving rod 1412 driving the movable seat 1423 to move axially along the guide rod 1411. Specifically, the movable seat 1423 has a third opening (not marked) and is fitted onto the outside of the guide rod 1411 through the third opening. The movable seat 1423 is driven by the drive rod 1412 to move axially along the guide rod 1411, thereby causing the first tongue plate 1421 and the second tongue plate 1422, which are laterally extended from the movable seat 1424, to move axially. Then, the drive rod 1412 adjusts the movable seat 1423 to the target axial position and fixes the movable fixed seat 1423 at the target axial position, thereby fixing the first tongue plate 1421 and the second tongue plate 1422 at the target axial position. The target axial position refers to the axial position of the first tongue plate 1421, the second tongue plate 1422, and the movable seat 1423 respectively when the axial length between the first tongue plate 1421 and the base plate 60 meets the width of the printed object, and when the axial length between the second tongue plate 1422 and the base plate 60 meets the width of the recycled object. The method by which the drive rod 1412 drives the movable seat 1423 to move axially can be determined, for example, by driving a motor and fixing the movable seat 1423 by opening several buckles on the drive rod 1412. This embodiment does not make specific limitations on this, as long as the drive rod 1412 can adjust the axial position of the movable seat 1423.

[0090] In one implementation, the reference Figure 18As shown, the movable seat 1423 has a fourth opening 1424 to be sleeved on the outside of the drive rod 1412. A first thread 14121 is formed on the outside of the drive rod 1412, and a second thread (not shown) that matches the first thread 14121 is formed on the inside of the fourth opening. By driving the drive rod 1412 to rotate axially along its central axis C5, the movable seat 1423 is moved axially along both the guide rod 1411 and the drive rod 1412, thereby adjusting the axial position of the movable seat 1423. Regarding the lateral extension of the first tongue plate 1421 and the second tongue plate 1422 from the portion of the movable seat 1423 sleeved on the guide rod 1411 or from the portion of the movable seat 1423 sleeved on the drive rod 1412, this embodiment does not specifically limit this. It can be that the first tongue plate 1421 extends laterally from the portion of the movable seat 1423 sleeved on the guide rod 1411 and the second tongue plate 1422 extends laterally from the portion of the movable seat 1423 sleeved on the drive rod 1412, or... The first tongue plate 1421 extends laterally from the portion of the movable seat 1423 that is fitted onto the drive rod 1412, and the second tongue plate 1422 extends laterally from the portion of the movable seat 1423 that is fitted onto the guide rod 1411. Alternatively, both the first tongue plate 1421 and the second tongue plate 1422 extend laterally from the portion of the movable seat 1423 that is fitted onto the guide rod 1411. Or, both the first tongue plate 1421 and the second tongue plate 1422 extend laterally from the portion of the movable seat 1423 that is fitted onto the drive rod 1412. Preferably, the first tongue plate 1421 extends laterally from the portion of the movable seat 1423 that is fitted onto the guide rod 1411, and the second tongue plate 1422 extends laterally from the portion of the movable seat 1423 that is fitted onto the drive rod 1412.

[0091] In one implementation, the reference Figure 5 As shown, the adjusting member 141 further includes a drive input portion 1413 disposed on the top of the drive rod 1412 to drive the drive rod 1412 to rotate axially, and the drive input portion 1413 is formed on the top of the substrate 131. By rotating the drive input portion 1413 along the central axis C5 of the drive rod 1412, the movable seat 1423 is driven to move axially upward or downward, thereby adjusting the axial position of the movable seat 1423, thus solving the problem of inconvenience in operation that requires adjusting the axial position of the movable seat 1423 by adjusting the side gear in the prior art.

[0092] In one implementation, the reference Figure 18As shown, the first tongue plate 1421 and the movable seat 1423 are configured as separate structures. The first tongue plate 1421 is sleeved on the outside of the guide rod 1411. The movable seat 1423 forms a first movable ring portion 14231 and a second movable ring portion 14232 that are sleeved on the outside of the guide rod 1411 and clamp the first tongue plate 1421. The first movable ring portion 14231 and the second movable ring portion 14232 jointly clamp the first tongue plate 1421, so that the axial movement of the movable seat 1423 can drive the axial movement of the first tongue plate 1421, and the axial position of the first tongue plate 1421 can be restricted by the first movable ring portion 14231 and the second movable ring portion 14232.

[0093] In one implementation, the reference Figure 19 As shown, the guide rod 1411 forms a fixed shaft section 14111 and a limiting shaft section 14112 in the axial upward direction along the guide rod 14111. The first tongue plate 1421 is sleeved on the outside of the limiting shaft section 14112 and moves axially along the limiting shaft section 14112. The limiting shaft section 14112 is radially reduced relative to the fixed shaft section 14111, so that the top surface of the fixed shaft section 14111 can abut against the bottom surface of the first tongue plate 1421 (i.e., when the first tongue plate 1421 and the movable seat 1423 are configured as an integral structure) or the bottom surface of the second movable ring 14232 (i.e., when the first tongue plate 1421 and the movable seat 1423 are configured as a separate structure), which can effectively prevent the first tongue plate 1421 from moving axially to an excessively low axial position (i.e., the axial length between the first tongue plate 1421 and the base plate 60 is too low).

[0094] In one implementation, the reference Figures 18 to 20As shown, in order to facilitate the passage of the printed object through the first conveying area A, the first tongue plate 1421 is configured to actively penetrate the first conveying area A. When the print head 21 and the pressure roller 11 are separated, the first tongue plate 1421 does not penetrate the first conveying area A (i.e., the first tongue plate 1421 is retracted inside the substrate 131). When the print head 21 and the pressure roller 11 are in contact, the first tongue plate 1421 penetrates the first conveying area A so that the first tongue plate 1421 and the base plate 60 together restrict the printed object. For example, the side of the limiting shaft segment 14112 forms a first limiting surface 14113 that restricts the axial rotation of the first tongue plate 1421. The first movable ring portion 14231 and the second movable ring portion 14232 are movably sleeved with the limiting shaft segment 14112, that is, the first movable ring portion 14231 and the second movable ring portion 14232 remain stationary when the limiting shaft segment 14112 rotates axially (or conversely, the first movable ring portion 14231 and the second movable ring portion 14232 remain stationary). 2. The first tongue plate 1421 is axially rotatable along the central axis C6 of the limiting shaft segment 14112. The hole 14211 with a limiting edge on the outer side of the limiting shaft segment 14112 matches the first limiting surface 14113. That is, the first tongue plate 1421 can move axially along the limiting shaft segment 14112 but cannot rotate axially along the limiting shaft segment 14112. When the limiting shaft segment 14112 rotates axially along the central axis C6, the first tongue plate 1421 rotates accordingly. The guide rod 1411 is driven to rotate axially by the linkage mechanism 80 located below the base plate 60, so as to drive the first tongue plate 1421 to move into the first conveying area A. When the first tongue plate 1421 enters the first conveying area A, the first tongue plate 1421 and the base plate 60 together restrict the printing object.

[0095] In one implementation, the reference Figure 19 and Figures 21 to 23As shown, the linkage mechanism 80 includes a first connecting rod 81 disposed below the base plate 60 and a second connecting rod 82 movably connected to one end of the first connecting rod 81. The end of the first connecting rod 81 away from the second connecting rod 82 is movably connected to the printing mechanism 20, and the end of the second connecting rod 82 away from the first connecting rod 81 is movably connected to the guide rod 1411. Specifically, one end of the first connecting rod 81 is sleeved on the outside of the drive head 235, and the other end has a protrusion 811. One end of the second connecting rod 82 is sleeved on the outside of the protrusion 811, and the other end is sleeved on the guide rod 1411, which extends axially downward and penetrates the guide portion 14114 of the base plate 60. One end of the elastic member 24 is sleeved on the outside of the fixed seat 63, and the other end is sleeved on the outside of the first connecting rod 81 where the drive head 235 is sleeved. The guide part 14114 has a second limiting surface 14115 on its side. One end of the second connecting rod 82 has a guide hole 821 formed on the outside of the guide part 14114, which is adapted to the second limiting surface 14115. When the second connecting rod 82 rotates around the central axis C6 of the guide rod 1411, it drives the guide rod 1411 to rotate around the central axis C6. The first connecting rod 81 is specifically located below the auxiliary plate 61, and the auxiliary plate 61 has an auxiliary protrusion 612 protruding downward. The first connecting rod 81 has an auxiliary hole 812 in the middle for the auxiliary protrusion 612 to pass through. The first connecting rod 81 is sleeved on the outside of the auxiliary protrusion 612 through the auxiliary hole 812 and can rotate around the central axis (not marked) of the auxiliary protrusion 612.

[0096] When the print head 21 is separated from the pressure roller 11, the knob 237 is rotated around the central axis C3 in the direction C32, which drives the drive head 235 to rotate along the arc-shaped hole 611 towards the side closer to the support column 236. This drives the first connecting rod 81 to rotate around the central axis of the auxiliary protrusion 612 in the direction C72, which in turn drives the second connecting rod 82 to rotate around the central axis C6 in the direction C61, so that the first tongue plate 1421 is in a state of retracting inside the substrate 131. When the print head 21 is in contact with the pressure roller 11, the knob 237 is rotated around the central axis C3 in the direction C31, which drives the drive head 235 to rotate along the arc-shaped hole 611 to the side away from the support column 236. This drives the first connecting rod 81 to rotate around the central axis of the auxiliary protrusion 612 in the direction C71, which in turn drives the second connecting rod 82 to rotate around the central axis C6 in the direction C62. This causes the first tongue plate 1421 to move into the first conveying area A, and the first tongue plate 1421 and the base plate 60 together restrict the printing object.

[0097] In one implementation, the reference Figure 24 and Figure 25As shown, one end of the first connecting rod 81 near the second connecting rod 82 extends laterally to form an impact end 813. The printing support mechanism 10 further includes a detection mechanism 90. The detection mechanism 90 includes a trigger controller 91 disposed below the bottom plate 60 and a detection unit 92 disposed between the printing support mechanism 10 and the printing mechanism 20 to detect the printed object being driven within the first transfer area A. After the trigger controller 91 is impacted by the impact end 813, the detection unit 92 is activated. Specifically, the trigger controller 91 is assembled below the mounting plate 93, the detection unit 92 is assembled above the mounting plate 93, and the mounting plate 93 is assembled below the bottom plate 60. The trigger controller 91 includes a reset switch 911 disposed on the side of one end of the first connecting rod 81 sleeved with the second connecting rod 82 and a terminal block 912 disposed on the side of the reset switch 911 away from the second connecting rod 82. Among them, the side of the reset switch 9靠近第二连杆82的侧面形成撞击面9111。在驱动打印头21与压辊11呈贴合状态时,第一连杆81绕辅助凸起部612所在中心轴线沿方向C71转动,以由撞击端813向靠近复位开关911的方向移动,并由撞击端813撞击撞击面9111以启动复位开关911,复位开关911向端子座912发射信号,进而启动检测单元92对第一传送区域A内被传动的打印对象进行检测,由此打印机构20与打印支承机构10夹持打印对象时,即可通过检测单元92对打印对象进行检测,并实现对第一张标签在从出口C处输出时即可被执行打印作业,以防止打印对象的浪费,从而解决现有技术中打印机在更换新的呈卷状的打印纸(即,打印对象的一种下位概念)时,需要先测试一张打印纸,长期以往存在纸张浪费且效率不高的问题。

[0098] As shown in the figure, the control mechanism 50 includes a first driving motor 51, a second driving motor 52 and a circuit board 53. Among them, both the first driving motor 51 and the second driving motor 52 are connected to the circuit board 51. A first gear assembly 54 is disposed at the bottom of the guide roller 12, and the first driving motor 51 drives the first gear assembly 54 to rotate to drive the guide wheel to rotate. A second gear assembly 55 is disposed at the bottom of the paper roll mounting mechanism 40, and the second driving motor 52 drives the second gear assembly 55 to drive the paper roll mounting mechanism 40 to rotate. Referring to Figure 3 and Figure 26 As shown in the figure, the control mechanism 50 further includes a cover 57 that integrally shields the first driving motor 51, the second driving motor 52 and the circuit board 53. The cover 57 is fixed to the bottom plate 60 by fasteners such as screws. Figure 1
