Description

Technical Field

[0001] The utility model relates to the technical field of printing consumables, in particular to a printing consumables box and a supporting baffle thereof. Background Art

[0002] A thermal printer's paper bin is currently equipped with a baffle that can slide and adjust its position along the axial direction of the paper roll. The baffle and the paper bin body are connected by slide rails, gear racks and other connecting structures to achieve smooth and stable sliding adjustment. The adjusted baffle can limit the paper roll placed in the paper bin from one axial side, and the adjustability of the baffle enables the printer to be used with a variety of paper roll consumables of different widths.

[0003] Now it is necessary to set a paper roll baffle inside the printing consumables box for covering the upper and lower parts.

[0004] Since the entire printing consumables cartridge is used as consumables and will be replaced as a whole when exhausted, the purpose of installing a baffle in the printing consumables cartridge is to use the same cartridge housing to adapt to different sizes of paper rolls, thereby saving the cost of the housing mold. In addition, it can also allow different sized paper rolls to have the same size housing to adapt to the printer.

[0005] It can be seen that, in fact, the baffle member in the printing consumables box does not need to slide, and only a baffle member that is adapted to the width of the paper roll needs to be fixedly installed; in addition, due to the limitation of the internal space size of the consumables box and for cost considerations, complex transmission structures such as slide rails and gear racks will not be set in a disposable printing consumables box.

[0006] On the other hand, the baffle of the printer paper bin only serves as a limit block. Different from this, the baffle in the printing consumables box also needs to position and support the axis of the paper roll. When the paper roll is unrolled, the baffle also needs to withstand the force. Obviously, the existing baffle design used in the printer paper bin cannot meet the needs of the baffle in the consumables box. Utility Model Content

[0007] The first purpose of the present utility model is to provide a support baffle suitable for installation in a cover-type printing consumables box, which not only limits the paper roll, but also can position the axis of the paper roll and provide a stable and reliable support effect.

[0008] A second object of the present invention is to provide a printing consumables box that can adapt to paper rolls of different widths.

[0009] The support baffle provided by the first purpose of the present utility model includes a plate body, and the printing consumables box includes a box body, a cover body and a paper tape roll core; the support baffle also includes a concentric first support shaft and a second support shaft, and the first support shaft and the second support shaft are respectively protruded on both sides of the thickness of the plate body, the first support shaft is used to support on the box body, and the second support shaft is used to be plugged into the roll core; a fixed buckle, a movable buckle and a first bayonet are set on the outer periphery of the plate body, the movable buckle has elastic deformation ability, the fixed buckle and the movable buckle are used to buckle with the box body, and the first bayonet is used to buckle with the cover body.

[0010] As can be seen from the above scheme, two support baffles are inserted on both sides of the paper tape roll core, and the first support shafts of the two support baffles are supported on the positioning grooves on both sides of the box body. The axial ends of the paper roll are supported and kept rotatable, and the rotation axis position of the paper roll is stabilized; the support baffles can be inserted into the box body of the consumables box in the radial direction and interlock with each other. After the cover body is closed, the support baffles can be locked and fixed. This ensures that the support baffles remain stable to cope with the forces they are subjected to during operation without deflection. The support baffle of the utility model not only effectively limits the paper roll, but also can position the axis of the paper roll and provide a stable and reliable support effect. It is very suitable for upper and lower cover printing consumables boxes.

[0011] A further solution is that the plate body can be inserted into the box body along the insertion direction, the fixed buckle and the movable buckle are arranged relative to each other along a first direction perpendicular to the insertion direction, and the insertion direction and the first direction are both perpendicular to the thickness direction of the plate body; the entrance of the first bayonet is exposed to the support baffle along the opposite direction of the insertion direction.

[0012] As can be seen from the above, under this configuration, the deformation of the dynamic buckle is triggered during the insertion of the plate into the box along the insertion direction, and the engagement of the fixed and dynamic buckles is completed simultaneously when the plate is inserted into place, reducing the difficulty of assembly. Furthermore, the fixed and dynamic buckles engage with the box from opposite sides of the plate, and the force applied to the support baffle is distributed at multiple points, preventing unilateral or localized force from causing displacement and changing the axis position during operation, which in turn affects the smoothness and stability of the paper roll discharge. The configuration of the first bayonet entrance being exposed to the support baffle in the direction opposite to the insertion direction ensures that the first bayonet entrance always faces the cover body, and engagement with the first bayonet entrance is completed during the closing of the cover body, similarly reducing the difficulty of assembly.

[0013] A further solution is that the plate body includes a cantilever extending along the first direction, and the first bayonet is arranged on the cantilever; the plate body includes an upright portion arranged at the front end in the insertion direction, and the fixed buckle is arranged on the upright portion; the plate body includes an elastic arm arranged at a distance from the upright portion along the first direction, and the movable buckle is arranged on the elastic arm.

[0014] As can be seen from the above, the present invention also takes into account the specific setting methods of the first bayonet, the fixed buckle and the movable buckle according to the actual situation inside the integrated printing consumables box. Mainly, an avoidance position for avoiding the carbon ribbon supply shaft can be formed between the cantilever and the vertical part.

[0015] A further solution is that the plate body includes an arc portion, the outer periphery of the arc portion includes an arc surface extending along the arc line, the arc surface is concentric with the first support axis, and the arc surface is arranged at the rear end of the plate body in the insertion direction; the cantilever, the upright portion and the elastic arm are all connected to the arc portion.

[0016] As can be seen above, to reduce the volume of the consumables box while ensuring space for accommodating the paper roll, the cover is designed with a semi-cylindrical inner and outer contour. The arc portion allows the support baffle to adapt to the inner contour of the cover, and the cooperation between the arc inner contour of the cover and the arc surface can be used to further limit the position.

[0017] A further solution is that, on the axial projection of the first support shaft, the fixed buckle, the movable buckle and the first bayonet are all located on the outer circumference of the circle where the arc surface is located.

[0018] As can be seen from the above, the diameter of the arc surface is larger than the maximum outer diameter of the paper roll. This arrangement can prevent the fixed buckle, the movable buckle and the first bayonet from interfering with the paper roll and affecting each other.

[0019] Another further solution is that the plate body includes an inner peripheral structure, ribs and an outer peripheral structure connected in sequence from the inside to the outside; the first support shaft and the second support shaft are connected to the inner peripheral structure; the fixed buckle, the movable buckle and the first bayonet are arranged on the outer peripheral structure; multiple ribs are radially distributed with the inner peripheral structure as the center, and hollow holes are arranged between two adjacent ribs; and / or, the support baffle is provided with an axial weight reduction hole, the axial weight reduction hole is arranged at the axial end of the first support shaft or the axial end of the second support shaft, and the axial weight reduction hole extends in the first support shaft and the second support shaft.

[0020] As can be seen above, the support baffle is large and requires two pieces. If the support baffle were a solid design, it would be heavy, increasing the weight of the consumables box. Therefore, the present invention utilizes a weight-reducing design in both the plate body and / or the support shaft. First, the plate body is provided with as many circumferentially arranged holes as possible, while the first and second support shafts are hollow. This significantly reduces the weight of the support baffle.

[0021] A further solution is to provide a raised first reinforcing rib on the inner wall surface of the hollow hole, and the first reinforcing rib is connected to the inner peripheral structure, the outer peripheral structure and two adjacent ribs.

[0022] In another further solution, the support baffle further includes a second reinforcing rib connected between the plate body and the first support shaft.

[0023] As can be seen from the above, a weight-reducing design for the support baffle will reduce the structural strength of the support baffle. The first reinforcing rib reinforces the plate body, and the second reinforcing rib reinforces the first support shaft.

[0024] The second object of the present invention is to provide a printing consumables box including the above-mentioned support baffle.

[0025] A further solution is that at least one of the following items is included: a first insertion position is provided in the box body, a first buckle position is provided in the first insertion position, one side of the plate body is inserted into the first insertion position, the first insertion position limits the plate body from the axial direction of the winding core, and the fixed buckle is buckled with the first buckle position; a second insertion position is provided in the box body, a second buckle position is provided in the second insertion position, the other side of the plate body is inserted into the second insertion position, the second insertion position limits the plate body from the axial direction of the winding core, and the dynamic buckle is buckled with the second buckle position; a plate extending along the axial direction of the winding core is provided on the cover body, a second bayonet is provided on the plate, the first bayonet and the second bayonet are plugged into each other, and the plate limits the plate body from the axial direction of the winding core.

[0026] As can be seen from the above, the first insertion position, the second insertion position and the second bayonet can all limit the axial direction of the support baffle, further ensuring that the support baffle is installed stably and reliably. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] See also Figures 1 to 4The support baffle 1 of this embodiment is integrally injection molded and includes a plate body 10, a first support shaft 18 and a second support shaft 19. The first support shaft 18 and the second support shaft 19 are concentrically arranged and protrude on both sides of the thickness of the plate body 10 respectively.

[0036] Functionally, the plate body 1 includes four parts: an arc portion 12 , a vertical portion 13 , an elastic arm 14 and a cantilever 15 .

[0037] The outer periphery of the arc portion 12 includes an arc-shaped surface 121 extending along an arc line. Arc-shaped surface 121 is concentric with the first support shaft 18 and is located at the rear end of the plate body 10 in the insertion direction of the support baffle 1. The negative z-axis in the diagram represents the insertion direction of the support baffle 1. The front end in the insertion direction is the lower end of the plate body 1 as shown in the diagram, and the rear end in the insertion direction is the upper end of the plate body 1 as shown in the diagram. Furthermore, in this embodiment, the semicircular arc-shaped surface 121 covers the rear half of the outer periphery of the plate body 1 in the insertion direction, that is, it covers the entire outer periphery above the position of the first support shaft 18 as shown in the diagram.

[0038] The upright portion 13 is provided at the front end of the support baffle 1 in the insertion direction. The upright portion 13 is generally rectangular and extends downward from below the first support shaft 18 along the insertion direction to the lower end of the plate body 1 shown in the figure. In the first direction, a fixing buckle 131 protruding outward along the first direction is provided on the first side of the front end of the upright portion 13. The fixing buckle 131 is provided with a guide slope that facilitates guiding the insertion. The above-mentioned first direction is perpendicular to the insertion direction, and both the insertion direction and the first direction are perpendicular to the plate thickness direction of the plate body 10. The y-axis direction shown in the figure is the above-mentioned first direction, and the first side in the first direction is the positive side of the y-axis shown in the figure.

[0039] The elastic arm 14 is spaced apart from the upright portion 13 in the first direction. In the first direction, the elastic arm 14 is located on the second side of the upright portion 13, i.e., on the negative side of the y-axis as shown. The elastic arm 14 extends in the insertion direction and has elastic deformation capability. Its extended end is an elastic free end, and is provided with a movable catch 141 that protrudes outward in the first direction. The protrusion direction of the movable catch 141 is opposite to that of the fixed catch 131, and the movable catch 141 and the fixed catch 131 are arranged opposite each other in the first direction. Similarly, the movable catch 141 is provided with a guiding slope.

[0040] The cantilever 15 extends outward along a first direction from a position slightly lower than the height of the first support shaft 18. In the first direction, the cantilever 15 and the elastic arm 14 are disposed on opposite sides of the upright portion 13. A first latch 151 is provided on the cantilever 15. The first latch 151 opens in the positive direction of the z-axis (as shown), i.e., in the direction opposite to the insertion direction. Furthermore, it can be seen that the first latch 151 is not obstructed by any other structure in front of it. In other words, the entrance of the first latch 151 is exposed to the support baffle 1 in the direction opposite to the insertion direction.

[0041] See especially Figure 3 In the axial projection of the first support shaft 18 , the fixed buckle 131 , the movable buckle 141 and the first bayonet 151 are all located on the outer periphery of the circle C where the arc surface 121 is located.

[0042] From another perspective, the plate body 10 comprises, from the inside out, an inner peripheral structure 111, ribs 113, and an outer peripheral structure 112, sequentially connected from the inside out. The first support shaft 18 and the second support shaft 19 are connected to the inner peripheral structure 111, while the aforementioned arc portion 12, upright portion 13, elastic arm 14, cantilever 15, fixed buckle 131, movable buckle 141, and first latch 151 are all located on the outer peripheral structure 112. Multiple ribs 113 extending radially along the first support shaft 18 are radiated from the inner peripheral structure 111, with a hollow hole 1130 defined between any two adjacent ribs 113.

[0043] See especially Figure 1 Furthermore, a raised first reinforcing rib 114 is provided on the inner wall surface of the hollow hole 1130 , and the first reinforcing rib 114 is connected to the inner peripheral structure 111 , the outer peripheral structure 112 and two adjacent ribs 113 .

[0044] See especially Figure 1 and Figure 4 Furthermore, the support baffle 1 is provided with an axial lightening hole 180, which is disposed at the axial end of the first support shaft 18 and extends into the first support shaft 18 and the second support shaft 19. The axial lightening hole 180 is a blind hole, and the end of the axial lightening hole 180 is blocked by the end of the second support shaft 19. The support baffle 1 also includes second reinforcing ribs 181 connected between the surface of the plate body 10 and the outer peripheral surface of the first support shaft 18. Four second reinforcing ribs 181 are evenly arranged along the circumference of the first support shaft 18.

[0045] Combine Figures 5 to 8 The printing consumables box of this embodiment includes a box body 8, a cover body 9, a paper tape 7 and its winding core 71, and two supporting baffles 1 of this embodiment.

[0046] See also Figure 5 and Figure 6 The first support shaft 18 is used to support the box body 8, and the second support shaft 19 is used to be plugged into the winding core 71. The paper tape 7 is wound on the winding core 71, and the second support shafts 19 of the two support baffles 1 are respectively plugged into the axial ends of the winding core 71, and the first support shafts 18 of the two support baffles 1 protrude from the axial ends of the winding core 71. The box body 8 is provided with positioning grooves 81 on both axial side walls of the winding core 71. When the paper tape 7, the winding core 71 and the two plugged support baffles 1 are placed together in the box body 8, the two first support shafts 18 are respectively placed in the two positioning grooves 81 and supported and limited by the box body 8.

[0047] See also Figure 6 and Figure 8 A first insertion position 82 is provided in the box body 8, and a first buckle position 83 is provided in the first insertion position 82. The first insertion position 82 is formed between two protrusions spaced apart along the axial direction of the winding core 71. The axial direction of the winding core 71 is consistent with the axial direction of the first support shaft 18. One side of the plate body 10 is inserted into the first insertion position 82, and the protrusions on both sides of the first insertion position 82 restrict the plate body 10 from the axial direction of the winding core 71. The fixed buckle 131 is buckled with the first buckle position 83, and the first buckle position 83 restricts the fixed buckle 131 from the opposite direction of the insertion direction.

[0048] See also Figure 7 and Figure 8 The box body 8 also includes a second insertion position 84, within which a second latching position 85 is located. The second insertion position 84 is formed between two protrusions spaced axially along the winding core 71. The other side of the plate 10 is inserted into the second insertion position 84. The protrusions on either side of the second insertion position 84 restrain the plate 10 axially along the winding core 71. The latch 141 engages with the second latching position 85, restraining the latch 141 in the direction opposite to the insertion direction.

[0049] See also Figure 8 The cover 9 is provided with a plate 91 extending along the axial direction of the winding core 71, and a second bayonet 911 is provided on the plate 91. The first bayonet 151 and the second bayonet 911 are plugged into each other, and the plate 91 restricts the plate 10 from the axial direction of the winding core 71. Figure 3 When the support baffle 1 is installed, it engages with the box body 8 via the fixed buckle 131 and the movable buckle 141. It engages with the cover body 9 via the first latch 151. The inner contour of the cover body 9 also cooperates with the arc surface 121. At this time, the freedom of movement of the support baffle 1 in all directions is effectively constrained and stabilized at the target axial position. In this way, the support baffle 1 remains stable to cope with the forces it is subjected to during operation without deflection. The support baffle of the utility model not only effectively restrains the paper roll, but also axially locates the paper roll and provides stable and reliable support. It is very suitable for upper and lower cover printing consumables boxes.

[0050] Also, see Figure 3 and Figure 8 A circumvention position 109 for circumventing the carbon ribbon supply shaft can be formed between the cantilever 15 and the upright portion 13. This arrangement enables the support baffle 1 to be suitable for an integrated printing consumables box that collects paper ribbons and carbon ribbons.

[0051] In other embodiments, the plate body is not provided with hollow holes, and the first support shaft and the second support shaft are not provided with weight-reducing holes.

[0052] In other embodiments, the plate body does not include an arc portion while meeting the matching requirements of the cover body of the consumable box.

[0053] Finally, it should be emphasized that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
