Description

Technical Field

[0001] This invention relates to the field of label printer technology, and in particular to a multifunctional label printer. Background Technology

[0002] Thermal printers, as label printing devices, are mainly used to print information on self-adhesive labels such as product price tags and express delivery slips. They separate the label face paper from the release paper and then affix it to the surface of the product or packaging. Existing handheld label printers typically include a housing, a thermal printing assembly, a label paper tray, and a peeling mechanism. The label paper has a composite structure, consisting of label face paper and release paper bonded together. Multiple label face papers are arranged sequentially along the length of the release paper. During printing, the thermal print head prints the preset content on the label face paper, and then the label paper tape is conveyed to the peeling mechanism.

[0003] The peeling mechanism is usually equipped with a peeling plate. Under the action of traction, the release paper folds back at a large angle along the tip of the peeling blade. Because the label paper is less rigid than the release paper, it cannot fold back along the same small radius path, thus separating from the release paper at the tip of the peeling blade. The separated release paper is recycled by the winding mechanism, while the label paper extends out from the paper outlet and is pasted to the target surface by the operator.

[0004] However, the separation reliability of a single-stage peel structure varies for label papers of different materials and adhesive properties. When the label face paper is weak or the adhesion between the release liner and the face paper is strong, relying solely on the single-point folding action at the peeling blade, the label face paper is difficult to completely separate from the release liner. Some of the face paper will fold back along with the release liner and enter the recycling channel, resulting in incomplete separation. Secondly, after the label face paper is separated from the release liner, it is prone to curling inward due to its own weight and paper flexibility. The adhesive layer on the back of the curled face paper may come into contact with the face paper itself and stick to it, or come into contact with the outer surface of the device and adhere to it, causing the face paper to be unable to be output smoothly and affecting subsequent pasting operations. Therefore, this application provides a multi-functional label printer to meet the needs. Summary of the Invention

[0005] The purpose of this invention is to provide a multifunctional label printer to solve the above-mentioned problems. By setting a push separator to apply a push force to the back of the back paper to form a point contact pre-separation and a sharp angle fold back for secondary separation at the peeling head, and by setting an overlapping roller with a dividing disc to support the front paper and prevent curling, the invention solves the problems mentioned in the background art of incomplete separation between the label front paper and the release paper, and the problem of the back paper curling downwards and sticking after separation.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A multifunctional label printer includes a housing and a cover hinged to its upper part. A thermal printhead is provided at the bottom of the cover and near its opening. A rotatable paper feed roller is provided inside the housing. A paper jammer is provided at the upper end of the housing near the opening. A handle is fixedly connected to the bottom of the housing. A winding mechanism for winding up the separated bottom paper is provided inside the housing.

[0008] A fixed frame is fixedly connected to the outside of the machine casing. A peeling plate, a peeling head, and an overlapping roller are arranged sequentially along the paper path inside the fixed frame. The peeling plate has symmetrically opened grooves inside, and a push separator is slidably connected inside the grooves. A paper pressure roller is also rotatably connected inside the fixed frame, and the paper pressure roller is located above the peeling plate. A bottom paper conveying gap is formed between the peeling head and the overlapping roller.

[0009] Optionally, mounting cavities are provided on both sides of the inner wall of the paper outlet of the housing. A slider is slidably connected inside the mounting cavity, and a conveying roller is rotatably connected between the two sliders. A first elastic element is fixedly connected between the slider and the top wall of the mounting cavity.

[0010] Optionally, the fixed frame has symmetrically formed constraint grooves, and both ends of the peeling head are fixedly connected with positioning screws. The positioning screws slide through the constraint grooves. When the positioning screws slide, they drive the peeling head to move, so as to adjust the distance between the peeling head and the overlapping roller. The positioning screws are externally threaded with fastening bolts.

[0011] Optionally, the outer side of the overlapping roller is equidistantly fitted with multiple dividing discs for supporting the separated labels, and the outer side of the dividing discs is provided with multiple conical teeth arranged in an axial array.

[0012] Optionally, two adjusting frames are symmetrically arranged inside the fixed frame. A bidirectional screw is rotatably connected inside the fixed frame, and both adjusting frames are threadedly connected to the bidirectional screw. A limiting ring is fixedly connected to one end of the adjusting frame. The limiting ring is coaxially sleeved on the outside of the overlapping roller, and the diameter of the hole of the limiting ring is larger than the diameter of the dividing disc.

[0013] Optionally, the push separator includes a fixed box slidably disposed in the slide groove, and the fixed box is fixedly connected to the top of the adjusting frame. A pressing head is slidably connected inside the fixed box, and the top end of the pressing head extends above the peeling plate. A second elastic element is provided between the bottom wall of the fixed box and the pressing head.

[0014] Optionally, the fixing frame is further provided with an elastic scraper and a brush plate. The elastic scraper is detachably connected to the top of the overlapping roller, and the brush plate is rotatably connected to the bottom of the overlapping roller.

[0015] Optionally, the winding mechanism includes a winding roller rotatably connected inside the housing. The winding roller has a clamping groove inside and an elastic clamping rod inserted inside the winding roller for clamping and fixing the end of the bottom paper in the clamping groove. A drive motor for driving the winding roller to rotate is installed inside the housing.

[0016] Optionally, the housing has a through groove for the bottom paper to pass through, and a guide roller is rotatably connected in the through groove to guide the bottom paper to the take-up roller.

[0017] Optionally, a paper feeding port is provided inside the housing and on one side of the take-up roller, and rails are symmetrically fixedly connected to the outside of the housing and on both sides of the paper feeding port. A sealing cover for blocking the paper feeding port is slidably connected between the two rails.

[0018] Compared with the prior art, the present invention has at least the following beneficial effects:

[0019] In the above solution, the multi-functional label printer provided in this application solves the problems of incomplete label separation and curling and sticking of the separated paper in the prior art by setting a two-stage separation structure consisting of a push separator and a peeling head, and a dividing disc on the overlapping roller that can rotate with the movement of the face paper. At the same time, by synchronously adjusting the lateral position of the limiting ring and the push separator with a bidirectional screw, it can meet the needs of rapid adaptation of label paper of different widths.

[0020] By setting a push separator upstream of the peeling plate, the squeezing head in the push separator extends upward from the surface of the peeling plate under the action of the elastic element and abuts against the back of the backing paper. It can apply an upward pushing force to the backing paper. This push transforms the line contact between the backing paper and the peeling plate into a local point contact. At the push point, the adhesive interface between the face paper and the backing paper is micro-separated, forming a first-level pre-separation. The peeling head can fold the backing paper back at a large angle along its end. With the combination of the acute angle fold and the pre-separation, the end of the face paper can be fully lifted off the backing paper, thereby enabling stable separation of label papers of different materials and adhesiveness, and preventing the face paper from entering the recycling channel with the backing paper.

[0021] By setting an overlap roller with a dividing disc below the paper output path, the paper extends horizontally after separation and is supported by the dividing disc below, which can prevent the paper from rolling inward after separation, ensuring smooth paper output and accurate pasting.

[0022] It is worth mentioning that during the equipment dragging and pasting process, the elastic scraper presses the face paper against the packaging surface. On the one hand, this can improve the adhesion of the face paper. On the other hand, it can create contact friction between the face paper and the dividing disc, thereby driving the overlapping roller and the dividing disc to rotate. This causes the conical teeth on the outer circumference of the dividing disc to make brief point contact with the self-adhesive on the back of the face paper, which can reduce the risk of adhesion between the face paper adhesive and the supporting components.

[0041] like Figures 1 to 4 As shown, an embodiment of the present invention provides a multifunctional label printer, including a housing 1 and a cover 2 hinged to the upper part of the housing 1. A thermal printhead 201 is provided at the bottom of the cover 2 near its opening. A rotatable paper feed roller 102 is provided inside the housing 1. A paper jammer 103 is provided at the upper end of the housing 1 near the opening. The paper jammer 103 is a laterally sliding limiting baffle structure. By adjusting its lateral position, it can adapt to label paper tapes of different widths and laterally limit the paper tape to prevent the paper tape from deviating to the left or right during the paper feeding process, thus affecting the printing position accuracy. A handle 101 is fixedly connected to the bottom of the housing 1. The handle 101 makes it easy for the operator to hold the device with one hand for operation, achieving the effect of printing and labeling immediately.

[0042] The inner wall of the paper outlet of the housing 1 has mounting cavities 104 on both sides. Slider 105 is slidably connected inside the mounting cavity 104. A conveying roller 106 is rotatably connected between the two sliders 105. A first elastic element 107 is fixedly connected between the slider 105 and the top wall of the mounting cavity 104. This floating pressing structure can effectively absorb the speed difference between the winding traction and the unloading inertia, prevent the paper belt from shaking and causing fluctuations, and ensure that the thermal print head (201) completes high-quality printing under stable paper feeding conditions.

[0043] In this embodiment, as Figures 5 to 7 As shown, a fixed frame 3 is fixedly connected to the outside of the housing 1. Inside the fixed frame 3, a peeling plate 4, a peeling head 6 and an overlapping roller 7 are arranged in sequence along the paper path direction. A bottom paper conveying gap is formed between the peeling head 6 and the overlapping roller 7.

[0044] like Figure 7 and Figure 9As shown, the peeling plate 4 has symmetrically arranged grooves 401 inside, which extend along the width of the paper strip. A push separator 5 is slidably connected inside the grooves 401. A pressure roller 301 is rotatably connected inside the fixing frame 3, and is located above the peeling plate 4. The function of the pressure roller 301 is to smoothly press the composite paper strip entering the peeling area onto the surface of the peeling plate 4, preventing the paper strip from warping or suspending before peeling, and ensuring that the push separator 5 can accurately act on the bottom paper at a preset position. The push separator 5 includes a fixing box 501 slidably disposed within the grooves 401. The part is slidably connected to the extrusion head 502, and the top of the extrusion head 502 extends above the peeling plate 4. A second elastic element 503 is provided between the bottom wall of the fixing box 501 and the extrusion head 502. Since in the traditional peeling structure, the peeling force depends entirely on the sharp angle of the peeling blade, high-adhesion or low-rigidity labels are easy to be incompletely separated. In this design, the extrusion head 502 is pushed upward from the slide groove 401 and abuts against the back of the backing paper under the action of the second elastic element 503, which transforms the line contact into a local point contact. Stress concentration is formed at the pushing point, which can produce a local pre-separation effect to assist in the subsequent complete separation.

[0045] like Figure 8 and Figure 9 As shown, two adjusting frames 8 are symmetrically arranged inside the fixed frame 3. A bidirectional screw 802 is rotatably connected inside the fixed frame 3, and both adjusting frames 8 are threadedly connected to the bidirectional screw 802. One end of the adjusting frame 8 is fixedly connected to a limiting ring 801. The limiting ring 801 is coaxially sleeved on the outside of the overlapping roller 7. Multiple dividing discs 701 are equidistantly sleeved on the outside of the overlapping roller 7 to support the separated labels. Multiple conical teeth are arranged in an axial array on the outside of the dividing discs 701, and the hole diameter of the limiting ring 801 is larger than the diameter of the dividing discs 701 to ensure that the limiting ring 801 will not interfere with the rotation of the dividing discs 701, while effectively limiting the lateral position of the paper.

[0046] Rotating the bidirectional screw 802 allows for simultaneous adjustment of the spacing between the two limiting rings 801 and the lateral position of the two push separators 5. This not only provides lateral centering of the face paper to prevent it from shifting or tilting during pasting, but also ensures that the pressure head 502 is always aligned with the appropriate pushing area of ​​the base paper, guaranteeing the stability of the pre-separation effect. Furthermore, the inner gap of the two adjusting frames 8 is adapted to the width of the base paper, allowing for the straightening of the base paper and preventing skewing during winding.

[0047] like Figure 7As shown, the fixed frame 3 has symmetrically arranged constraint grooves 302. Both ends of the peeling head 6 are fixedly connected to positioning screws. The positioning screws slide through the constraint grooves 302. When the positioning screws slide, they drive the peeling head 6 to move, thereby adjusting the distance between the peeling head 6 and the overlapping roller 7. The positioning screws are externally threaded with fastening bolts 601. By adjusting the position of the peeling head 6, the tilt angle of the bottom paper after folding back to the guide roller 10 can be changed. This design allows the equipment to adjust the peeling angle according to the thickness and adhesion of the label paper. For thicker or more viscous label paper, the peeling angle can be appropriately increased to provide greater peeling force. For thinner or easily torn label paper, the peeling angle can be appropriately decreased to avoid tearing of the face paper.

[0048] like Figure 6 and Figure 7 As shown, the fixed frame 3 is also equipped with an elastic scraper 303 and a brush 304. The elastic scraper 303 is detachably connected to the upper part of the overlapping roller 7, and the brush 304 is rotatably connected to the lower part of the overlapping roller 7. A torsion spring (not shown in the figure) is provided on the rotating shaft of the brush 304, which can press the brush 304 against the packaging bag, so that it cleans the area to be pasted as the equipment moves, reducing the problem of poor pasting due to unclean pasting surface.

[0049] like Figure 6 As shown, the housing 1 is equipped with a winding mechanism 9 for winding up the separated bottom paper. The winding mechanism 9 includes a winding roller 901 rotatably connected inside the housing 1. The winding roller 901 has a clamping groove 9011 inside, and an elastic clamping rod 9012 is inserted into the winding roller 901 to clamp and fix the end of the bottom paper in the clamping groove 9011. The elastic clamping rod 9012 is preferably a U-shaped rod formed by bending an elastic metal wire, with its two arms inserted into the winding mechanism. The middle section of the roller 901 is pressed into the clamping groove 9011 in the insertion holes at both ends. When loading paper, the bottom paper end is inserted into the clamping groove 9011, and then the elastic clamping rod 9012 is pressed in to firmly clamp the bottom paper. The housing 1 is equipped with a drive motor 902 for rotating the take-up roller 901. The housing 1 has a through groove for the bottom paper to pass through, and a guide roller 10 is rotatably connected in the through groove to guide the bottom paper to the take-up roller 901.

[0050] Furthermore, such as Figure 1 and Figure 2 As shown, a paper take-up port is provided inside the housing 1 and on one side of the take-up roller 901. Tracks 108 are symmetrically fixedly connected to the outside of the housing 1 and on both sides of the paper take-up port. A sealing cover 109 for sealing the paper take-up port is slidably connected between the two tracks 108. The sealing cover 109 and the track 108 are interference fit to ensure that the sealing cover 109 will not slide open on its own during the use of the equipment. When the bottom paper is wound to a certain amount, the operator can slide open the sealing cover 109 and conveniently take out the waste paper roll from the paper take-up port without opening the entire housing.

[0051] Working principle of the invention:

[0052] Before use, the operator adjusts the equipment according to the width of the label paper, adjusts the lateral spacing of the paper jammer 103 to match the width of the label paper, so as to limit the paper tape laterally and prevent the paper from deviating. Rotating the bidirectional screw 802 drives the two adjusting frames 8 to move synchronously. During this process, the limiting ring 801 and the fixing box 501 move with the adjusting frame 8, so that the pushing position of the pressing head 502 is aligned with the appropriate area of ​​the bottom paper. At the same time, the gap between the two adjusting frames 8 can also be used to sort the folded bottom paper to prevent the bottom paper from deviating during winding, and push the peeling head 6 to move. At this time, the positioning screws at both ends of the peeling head 6 are adjusted to slide in the constraint groove 302 to adapt to the thickness of the current label paper and the required peeling angle. After the adjustment is completed, the position of the peeling head 6 is fixed by the fastening bolt 601.

[0053] After adjustment, the roll of self-adhesive label paper is loaded into the machine housing 1, and the paper tape head is pulled out. It passes through the conveyor roller 106, the paper jammer 103, and the thermal print head 201 in sequence, and then is led to the surface of the peeling plate 4. The bottom paper head is folded down around the tip of the peeling head 6, and after being reversed by the guide roller 10, it is fixed in the clamping groove 9011 of the take-up roller 901 and pressed by the elastic clamping rod 9012.

[0054] In use, the operator holds the device with one hand using the handle 101, places the front end of the fixing frame 3 against the surface of the product packaging to be labeled, and triggers the printing task. The drive motor 902 drives the take-up roller 901 to rotate and take up the bottom paper, generating traction force to pull the entire label paper tape forward. The paper feed roller 102 then passively rotates to feed the material. During this process, the conveyor roller 106, under the action of the first elastic element 107, floats and presses the paper tape in the mounting cavity 104 through the slider 105.

[0055] After printing, the composite paper tape enters the fixing frame 3 and is smoothly pressed onto the surface of the peeling plate 4 by the pressure roller 301. At this time, the push separator 5 starts to work: the second elastic element 503 in the fixing box 501 pushes the extrusion head 502 upward. The top of the extrusion head 502 extends from the slide groove 401 and abuts against the back of the bottom paper, applying an upward normal pushing force to the bottom paper. The magnitude of this pushing force adapts to the softness and hardness of the paper tape material. When the paper tape is more rigid, the pushing force is relatively larger, and when the paper tape is soft, the pushing force is correspondingly reduced, thereby ensuring that a suitable pre-separation force can be provided for label papers of different materials. The pushing of the extrusion head 502 transforms the surface contact or line contact between the bottom paper and the peeling plate 4 in the traditional peeling structure into a local point contact lifting, so that the bonding interface between the face paper and the bottom paper produces micro-separation at the pushing point, creating conditions for subsequent complete separation.

[0056] As the paper belt continues to move forward, the bottom paper is folded back at a large angle along the tip of the peeling head 6 under the action of traction, passing through the bottom paper conveying gap between the peeling head 6 and the overlapping roller 7. Since the tip of the peeling head 6 forms an acute angle folding path, the top paper is completely lifted at the tip of the peeling head 6, achieving complete separation.

[0057] After complete separation, the face paper extends forward in a horizontal position, supported below by the dividing disc 701 on the overlapping roller 7 to prevent the face paper from curling downwards due to gravity or flexibility. During this process, the elastic scraper 303 is located above the overlapping roller 7 and applies a slight pressing force to the face paper as the equipment is dragged to press the face paper against the packaging surface. The face paper and the dividing disc 701 generate contact friction due to the pressing action of the elastic scraper 303. This friction causes the overlapping roller 7 and the dividing disc 701 to rotate with the movement of the face paper. When the dividing disc 701 rotates, the conical teeth on its outer circumference make brief point contact with the self-adhesive layer on the back of the face paper, thereby greatly reducing the risk of adhesion between the face paper adhesive and the supporting components and ensuring smooth output of the face paper. At the same time, the two limiting rings 801 can laterally center the face paper to prevent the face paper from shifting or tilting during pasting.

[0058] During the backward movement of the equipment, the brush plate 304 located below the overlapping roller 7 is always pressed against the packaging surface under the action of the torsion spring. Before the face paper is pasted, the area to be pasted is pre-cleaned to remove dust and other impurities. The cleaned area then accepts the face paper pasting. Under the pressing action of the elastic scraper 303, the face paper can be firmly pasted. The separated bottom paper is folded back down from the conveying gap between the peeling head 6 and the overlapping roller 7. After being reversed by the guide roller 10, it is continuously wound onto the winding roller 901. When the bottom paper is wound to a certain amount, the sealing cover 109 is slid open, and the waste paper roll can be taken out from the paper dispensing port.
