Technical Field
[0001] This application relates to the field of printing component technology, specifically to printheads and printing equipment. Background Technology
[0002] Heat transfer printing is a technique that transfers patterns or text from a transfer medium to the surface of a target object. By heating and applying pressure, the ink or pigment on the transfer paper sublimates and penetrates into the object being transferred. It can achieve high-precision, rich-color pattern transfer and meet the personalized customization needs of objects of different shapes and materials. It is widely used in advertising, gift making, clothing printing and dyeing and other industries.
[0003] In related technologies, in order to achieve wide-format printing, multiple thermal sheets are usually spliced along the width direction and distributed on two fixed surfaces in a V shape. The splicing points of two adjacent thermal sheets are partially overlapped to achieve wide-format printing. However, in order to adjust the position of the thermal sheets, there is usually a gap between the two fixed surfaces, which can jam the end of the printing paper and make it inconvenient for operators to operate.

[0039] Among related technologies, heat transfer printing is a technique that transfers patterns or text from a transfer medium to the surface of a target object. Through high temperature and high pressure, the ink or pigment on the transfer paper sublimates and penetrates into the object being transferred. It can achieve high-precision and colorful pattern transfer, and can meet the personalized customization needs of objects of different shapes and materials. It is widely used in advertising, gift making, clothing printing and dyeing and other industries.
[0040] To achieve wide-format printing, multiple thermal sheets are typically spliced together along the width and distributed on two fixed surfaces in a V-shape. The splicing points of two adjacent thermal sheets are partially overlapped to achieve wide-format printing. However, in order to adjust the position of the thermal sheets, there is usually a gap between the two fixed surfaces, which can jam the end of the printing paper and make it inconvenient for operators to operate.
[0041] To address the aforementioned technical problems, this application provides a printhead and printing device that can prevent paper from jamming and simplify operation.
[0042] The following is combined Figures 1 to 9 This describes an embodiment of the present application.
[0043] According to embodiments of this application, in one aspect, a printhead is provided, such as... Figures 1 to 5 As shown, it includes a mounting bracket 1, multiple heating printing components 2 and a guide component 3, and the specific solution is as follows.
[0044] like Figure 1 and Figure 2 As shown, the mounting bracket 1 is provided with a first mounting part 11 and a second mounting part 12. The first mounting part 11 is provided with a first mounting surface 111, and the second mounting part 12 is provided with a second mounting surface 121. The first mounting surface 111 and the second mounting surface 121 are arranged at an angle, specifically, the angle is 120° to 160°, preferably any angle selected from 120°, 125°, 130°, 135°, 140°, 145°, 150°, 152°, 155°, and 160°. Figure 5 As shown, there is an isolation space 13 between the first mounting part 11 and the second mounting part 12; specifically, the cross-section of the isolation space 13 can be any shape, such as rectangular, trapezoidal, etc., as long as it can meet the adjustment of the heating printing component 2, and is preferably rectangular.
[0045] like Figure 2 As shown, multiple heating printing components 2 are sequentially arranged along the printing width direction X, with at least one heating printing component 2 disposed on the first mounting surface 111 and at least one heating printing component 2 disposed on the second mounting surface 121; as Figure 2 As shown, at least one heating printing component 2 is provided on the first mounting surface 111, and at least one heating printing component 2 is provided on the second mounting surface 121.
[0046] It should be noted that at least one heating printing component 2 is disposed on the first mounting surface 111 and at least one heating printing component 2 is disposed on the second mounting surface 121. Specifically, multiple heating printing components 2 are spliced together along the printing width direction X. In any two adjacent heating printing components 2, one can be located on the first mounting surface 111 and the other on the second mounting surface 121, or both can be located on the first mounting surface 111 or the second mounting surface 121.
[0047] When any two adjacent heating printing components 2 are positioned such that one is on the first mounting surface 111 and the other is on the second mounting surface 121, the two heating printing components 2 can be spaced apart along the printing width direction X or partially overlapped, so that the heating printheads 22 on the two heating printing components 2 are spaced apart along the printing direction Y and connected along the printing width direction X.
[0048] When any two adjacent heating printing components 2 are both located on the first mounting surface 111 or the second mounting surface 121, the two heating printing components 2 can be spaced apart along the printing width direction X, or they can be partially overlapped, so that the heating printheads 22 on the two heating printing components 2 are spaced apart along the printing direction Y and connected along the printing width direction X.
[0049] like Figure 3 As shown, the guide component 3 is disposed within the isolation space 13, as... Figure 4 As shown, the guide component 3 is provided with a transition surface 34, which can guide the end of the printing material. One specific solution is as follows: Figure 4 As shown, the transition surface 34 smoothly connects the first mounting surface 111 and the second mounting surface 121. Specifically, the transition surface 34 can be a plane, an arc surface, or any other surface that can achieve a transition connection.
[0050] In specific usage, such as Figure 3 As shown, the printing roller 5 is positioned close to the first mounting surface 111 and the second mounting surface 121, and is at the same distance from the first mounting surface 111 and the second mounting surface 121 (distance refers to the minimum distance between the printing roller 5 and the first mounting surface 111 or the second mounting surface 121).
[0051] like Figure 4 As shown, when the end of the printing material (such as thermal printing paper) passes between the printing roller 5 and the first mounting surface 111 and the second mounting surface 121, the transition surface 34 on the guide assembly 3 plays a guiding role, preventing the end of the printing material from entering the isolation space 13, and guiding the printing material to the preset printing path direction.
[0052] In this embodiment, such as Figure 4 As shown, by providing a guide component 3 in the isolation space 13 between the first mounting surface 111 and the second mounting surface 121 which are set at an angle, the end of the printing material is prevented from entering the isolation space 13 and the end of the printing material is guided to the preset printing path direction, thereby simplifying the operation.
[0053] In one embodiment, such as Figure 4 As shown, the guide 31 is an integral component, such as a rubber block or other plastic part that can be fitted into the isolation space 13.
[0054] If the guide 31 is a rubber block, the specific process of its formation is as follows: molten glue is injected into the isolation space 13, and the glue overflowing from the isolation space 13 is scraped off by an arc-shaped scraper to form a transition surface 34. After the glue cools and solidifies, the guide 31 is formed.
[0055] In one embodiment, such as Figure 2 As shown, at least one part of the heating printing component 2 near the isolation space 13 is part of the edge of the isolation space 13, that is, the part of the heating printing component 2 near the isolation space 13 acts as part of the edge of the isolation space 13.
[0056] like Figure 5 As shown, guide member 31 is an elastic member, which can be a component made of any material with elastic expansion and contraction deformation. This expansion and contraction deformation can be formed by the material properties of the component, such as a rubber block; or it can be formed by the component having a shape that allows for expansion and contraction deformation, such as... Figure 5 As shown, a flexible tube is preferably used, which extends along the printing width direction X. The flexible tube is an existing product and can be purchased on the market. The molding part 32 is a part that can be melted under certain conditions and shaped under other conditions, such as UV glue (UV, Ultraviolet Rays). The molding part 32 is in contact with the guide 31. Of course, the molding part 32 and the guide 31 can also not be in contact, that is, they can be spaced apart. Preferably, the molding part 32 and the guide 31 are in contact. The transition surface 34 is provided on the side of the molding part 32 away from the guide 31. The transition surface 34 on the molding part 32 smoothly transitions to the first mounting surface 111 and the second mounting surface 121.
[0057] Preferably, a guide surface can also be provided on the guide member 31, and the guide surface has the same shape as the transition surface 34.
[0058] In specific use, such as during the debugging of the print head, if the printed sample has wrinkles or other problems, the positions of multiple heating printing components 2 need to be finely adjusted multiple times for verification. This requires frequent disassembly of the heating printing components 2. Taking the guide 31 as an example, the guide block needs to be cooled and molded multiple times, which increases the debugging time.
[0059] The guide assembly 3 includes a guide 31 and a shaping component 32, with the shaping component 32 being a rubber block as an example.
[0060] During the printhead debugging process, after the installation of the heating printing component 2 is completed, the debugging block can be directly installed into the isolation space 13 to serve as a pre-guide for debugging, thus eliminating the need to set up the glue block and improving the debugging speed; after the printing effect is debugged, the glue block is then made.
[0061] In this embodiment, such as Figure 5 As shown, the guide component 3 includes a guide 31 and a shaping component 32. The shaping component 32 can be adapted and transitioned to the edge of the isolation space 13 after the position is adjusted, thereby improving the guiding effect on the end of the printing material.
[0062] At the same time, such as Figure 5 As shown, the guide 31 reduces the amount of molding part 32 used, thereby avoiding shrinkage and depression after the molding part 32 cools down, and further improving the guiding effect on the end of the printing material.
[0063] In one embodiment, such as Figure 5 As shown, the bottom of the guide component 3 and the isolation space 13 are spaced apart, and the guide component 3 and the bottom of the isolation space 13 do not contact each other, thus providing a certain degree of spatial isolation and reducing the volume of the guide component 3.
[0064] In one embodiment, such as Figure 5 As shown, the guide component 3 is provided with multiple support parts 33. Specifically, the support parts 33 can be support rods or support cylinders, etc. The multiple support parts 33 are spaced apart along the printing width direction X. The ends of the support parts 33 away from the guide component 3 abut against the interior of the isolation space 13. The provision of the support parts 33 can restrict the guide component 3 from moving towards the bottom of the isolation space 13.
[0065] And / or, at least one of the two sides of the guide component 3 that contact the isolation space 13 is provided with an anti-slip part; that is, any one of the two sides of the isolation space 13 that contact the guide component 3 may be provided with an anti-slip part, or both sides may be provided with an anti-slip part; specifically, the anti-slip part is a frosted surface, or a surface with multiple protrusions, or other surfaces that can restrict the movement of the guide component 3, etc.
[0066] And / or, of the side of the first mounting part 11 facing the isolation space 13 and the side of the second mounting part 12 facing the isolation space 13, at least one side is a stepped surface, which can restrict the guide component 3 from moving towards the bottom of the isolation space 13; specifically, the stepped surface can be a two-step surface or a three-step surface. In the case of a three-step surface, preferably, the three stepped surfaces form a concave shape to limit the guide component 3 in two directions.
[0067] In this embodiment, such as Figure 4 As shown, by setting at least one of the support part 33, the anti-slip surface and the stepped surface, the guide component 3 can be limited to prevent the guide component 3 from moving in the isolation space 13, affecting the matching connection between the transition surface 34 and the first mounting surface 111 and the second mounting surface 121, thereby affecting the guiding effect.
[0068] In one embodiment, such as Figure 2 As shown, multiple heating printing components 2 are alternately arranged on the first mounting surface 111 and the second mounting surface 121 along the printing width direction X. Specifically, the multiple heating printing components 2 are arranged along the printing width direction X, with the heating printing components 2 at odd-numbered positions on the first mounting surface 111 and the heating printing components 2 at even-numbered positions on the second mounting surface 121. Alternatively, the heating printing components 2 at odd-numbered positions can be arranged on the second mounting surface 121 and the heating printing components 2 at even-numbered positions can be arranged on the first mounting surface 111.
[0069] like Figure 2 As shown, any two adjacent heating printing components 2 partially overlap along the printing width direction X. By setting the partial overlap, the heating printheads 22 on the heating printing components 2 can be aligned in the printing width direction X, because the heating printheads 22 and the boundary of the heating printing components 2 have a certain distance.
[0070] In one embodiment, such as Figure 2 As shown, the heating printing assembly 2 includes a mounting component 21 and a heating printhead 22. The heating printhead 22 is mounted on the mounting component 21 by welding or other means. Specifically, the mounting component 21 is provided with the control circuit of the heating printhead 22.
[0071] In one embodiment, such as Figure 2As shown, the heating printing assembly 2 located on the first mounting part 11 has a mounting component 21 embedded in the first mounting surface 111, and the heating surface of the heating printhead 22 protrudes from the first mounting surface 111. Specifically, the first mounting surface 111 is provided with a receiving groove to allow the mounting component 21 to be embedded in the first mounting surface 111. The heating surface of the heating printhead 22 only slightly protrudes from the first mounting surface 111. Specifically, the protrusion height is 0.1mm to 1mm, which can be any one or any two values of 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm and 1mm.
[0072] And / or, such as Figure 2 As shown, the heating printing assembly 2 located on the second mounting part 12 has a mounting component 21 embedded in the second mounting surface 121, and the heating surface of the heating printhead 22 protrudes from the second mounting surface 121. Specifically, the second mounting surface 121 is provided with a receiving groove to allow the mounting component 21 to be embedded in the second mounting surface 121. The heating surface of the heating printhead 22 only slightly protrudes from the second mounting surface 121. Specifically, the protrusion height is 0.1mm to 1mm, which can be any one or any two values of 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm and 1mm.
[0073] It should be noted that the portion of the receiving groove facing the isolation space 13 can be open, so that the portion of the mounting component 21 facing the isolation space 13 becomes part of the edge of the isolation space 13.
[0074] In this embodiment, such as Figure 2 As shown, by embedding the mounting component 21 on the first mounting surface 111 or the second mounting surface 121, and making the heating surface of the printing heating head flush with the first mounting surface 111 or the second mounting surface 121, the flatness of the printing material can be improved, and problems such as wrinkles during printing can be avoided.
[0075] In one embodiment, such as Figure 3 As shown, the first mounting part 11 is a first heat dissipation component; and / or, the second mounting part 12 is a second heat dissipation component; specifically, both the first heat dissipation component and the second heat dissipation component are heat dissipation plates, and heat dissipation fins are provided on the heat dissipation plates; the first heat dissipation component and the second heat dissipation component can also be water-cooled heat dissipation plates or other components with heat dissipation functions; more specifically, the first heat dissipation component and the second heat dissipation component are fixed to the mounting bracket 1 by multiple screws.
[0076] In one embodiment, such as Figure 7 As shown and Figure 8 The printhead also includes multiple heated printing blocks 4 ( Figure 6 (This is a schematic diagram of the printhead without the heated printing block 4 installed.) Figure 7 and Figure 9 As shown, the heated printing block 4 includes a block body 41, the cross-section of which is the same as the cross-section of the heated printing component 2. Multiple heated printing blocks 4 are respectively set on the first mounting surface 111 and the second mounting surface 121 by bolt connection. The heated printing component 2 and the heated printing blocks 4 are arranged along the printing width direction X on the first mounting surface 111 and the second mounting surface 121.
[0077] It should be noted that at this time, the transition surface 34 of the guide component 3 is used to transition between the edge of the heated printing block 4 and the edge of the heated printing component.
[0078] Specifically, the heating printing component 2 is partially embedded on the first mounting surface 111 or the second mounting surface 121. The heating surface of the heating print head 22 located on the first mounting surface 111 is higher than the first mounting surface 111, and the heating surface of the heating print head 22 located on the second mounting surface 121 is higher than the second mounting surface 121.
[0079] Or, such as Figure 6 As shown, the heating printing component 2 is directly stacked on the first mounting surface 111 or the second mounting surface 121.
[0080] Specifically, the heat-printed imitation block 4 is a plastic part, preferably with high resistance to deformation.
[0081] In this embodiment, the heated printing block can make the printing material flatter along the printing width direction X, avoiding wrinkles and preventing printing quality problems.
[0082] In one embodiment, such as Figure 7 and Figure 9 As shown, the heated printing block 4 also includes an extension 42. The cross-section of the extension 42 is the same as the cross-section of the thermal head on the heated printing assembly 2. At least one end of the block body 41 is provided with an extension 42. In adjacent heated printing assemblies 2 and heated printing blocks 4, the extension 42 is fitted to the end face of the protrusion on the heated printing assembly 2.
[0083] In this embodiment, by providing the extension 42, the gap between the heated print head 22 and the heated printing block 4 can be further eliminated, thereby further avoiding wrinkles in the printing material and improving print quality.
[0084] In one embodiment, a printhead is provided, such as Figures 1 to 5 As shown, it includes a mounting bracket 1, multiple heating printing components 2 and a guide component 3, and the specific solution is as follows.
[0085] like Figure 1 and Figure 2 As shown, the mounting bracket 1 is provided with a first mounting part 11 and a second mounting part 12. The first mounting part 11 is provided with a first mounting surface 111, and the second mounting part 12 is provided with a second mounting surface 121. The first mounting surface 111 and the second mounting surface 121 are arranged at an angle, specifically, the angle is 120° to 160°, preferably any angle selected from 120°, 125°, 130°, 135°, 140°, 145°, 150°, 152°, 155°, and 160°. Figure 5 As shown, there is an isolation space 13 between the first mounting part 11 and the second mounting part 12; specifically, the cross-section of the isolation space 13 can be any shape, such as rectangular, trapezoidal, etc., as long as it can meet the adjustment of the heating printing component 2, and is preferably rectangular.
[0086] like Figure 2 As shown, multiple heating printing components 2 are sequentially arranged along the printing width direction X, with at least one heating printing component 2 disposed on the first mounting surface 111 and at least one heating printing component 2 disposed on the second mounting surface 121; as Figure 2 As shown, at least one heating printing component 2 is provided on the first mounting surface 111, and at least one heating printing component 2 is provided on the second mounting surface 121.
[0087] More specifically, such as Figure 2 As shown, multiple heating printing components 2 are alternately arranged on the first mounting surface 111 and the second mounting surface 121 along the printing width direction X. Specifically, the multiple heating printing components 2 are arranged along the printing width direction X, with the heating printing components 2 at odd-numbered positions on the first mounting surface 111 and the heating printing components 2 at even-numbered positions on the second mounting surface 121. Alternatively, the heating printing components 2 at odd-numbered positions can be arranged on the second mounting surface 121 and the heating printing components 2 at even-numbered positions can be arranged on the first mounting surface 111.
[0088] like Figure 2 As shown, any two adjacent heating printing components 2 partially overlap along the printing width direction X. By setting the partial overlap, the heating printheads 22 on the heating printing components 2 can be aligned in the printing width direction X, because the heating printheads 22 and the boundary of the heating printing components 2 have a certain distance.
[0089] like Figure 3 As shown, the guide component 3 is disposed within the isolation space 13, as... Figure 4 As shown, the guide component 3 is provided with a transition surface 34, which can guide the end of the printing material. One specific solution is as follows: Figure 4As shown, the transition surface 34 smoothly connects the first mounting surface 111 and the second mounting surface 121. Specifically, the transition surface 34 can be a plane, an arc surface, or any other surface that can achieve a transition connection.
[0090] More specifically, such as Figure 2 As shown, at least one part of the heating printing component 2 near the isolation space 13 is part of the edge of the isolation space 13, that is, the part of the heating printing component 2 near the isolation space 13 acts as part of the edge of the isolation space 13.
[0091] like Figure 5 As shown, the guide assembly 3 includes a guide member 31 and a shaping member 32. Specifically, the guide member 31 is an elastic member, which can be a component made of any material with elastic expansion and contraction deformation. This expansion and contraction deformation can be formed by the material properties of the component, such as a rubber block; or it can be formed by the component having a shape that allows for expansion and contraction deformation, such as... Figure 5 As shown, a flexible tube is preferably used, which extends along the printing width direction X. The flexible tube is an existing product and can be purchased on the market. The molding part 32 is a part that can be melted under certain conditions and shaped under other conditions, such as UV glue (UV, Ultraviolet Rays). The molding part 32 is in contact with the guide 31. Of course, the molding part 32 and the guide 31 can also not be in contact, that is, they can be spaced apart. Preferably, the molding part 32 and the guide 31 are in contact. The transition surface 34 is provided on the side of the molding part 32 away from the guide 31. The transition surface 34 on the molding part 32 transitionally connects the first mounting surface 111 and the second mounting surface 121.
[0092] Preferably, a guide surface can also be provided on the guide member 31, and the guide surface has the same shape as the transition surface 34.
[0093] More specifically, such as Figure 5 As shown, the bottom of the guide component 3 and the isolation space 13 are spaced apart, and the guide component 3 and the bottom of the isolation space 13 do not contact each other, thus providing a certain degree of spatial isolation and reducing the volume of the guide component 3.
[0094] More specifically, such as Figure 5 As shown, the guide component 3 is provided with multiple support parts 33. Specifically, the support parts 33 can be support rods or support cylinders, etc. The multiple support parts 33 are spaced apart along the printing width direction X. The ends of the support parts 33 away from the guide component 3 abut against the interior of the isolation space 13. The provision of the support parts 33 can restrict the guide component 3 from moving towards the bottom of the isolation space 13.
[0095] At least one of the two sides of the guide component 3 that contact the isolation space 13 is provided with an anti-slip part; that is, any one of the two sides of the isolation space 13 that contact the guide component 3 may be provided with an anti-slip part, or both sides may be provided with an anti-slip part; specifically, the anti-slip part is a frosted surface, or a surface with multiple protrusions, or other shaped surfaces that can restrict the movement of the guide component 3.
[0096] Of the first mounting part 11 facing the isolation space 13 and the second mounting part 12 facing the isolation space 13, at least one side is a stepped surface. The stepped surface can restrict the guide component 3 from moving towards the bottom of the isolation space 13. Specifically, the stepped surface can be a two-step surface or a three-step surface. In the case of a three-step surface, preferably, the three stepped surfaces form a concave shape to limit the guide component 3 in two directions.
[0097] More specifically, such as Figure 2 As shown, the heating printing assembly 2 includes a mounting component 21 and a heating printhead 22. The heating printhead 22 is mounted on the mounting component 21 by welding or other means. Specifically, the mounting component 21 is provided with the control circuit of the heating printhead 22.
[0098] More specifically, such as Figure 2 As shown, the heating printing assembly 2 located on the first mounting part 11 has a mounting component 21 embedded in the first mounting surface 111, and the heating surface of the heating printhead 22 protrudes from the first mounting surface 111. Specifically, the first mounting surface 111 is provided with a receiving groove to allow the mounting component 21 to be embedded in the first mounting surface 111. The heating surface of the heating printhead 22 only slightly protrudes from the first mounting surface 111. Specifically, the protrusion height is 0.1mm to 1mm, which can be any one or any two values of 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.8mm, 0.7mm, 0.9mm and 1mm.
[0099] like Figure 2 As shown, the heating printing assembly 2 located on the second mounting part 12 has a mounting component 21 embedded in the second mounting surface 121, and the heating surface of the heating printhead 22 protrudes from the second mounting surface 121. Specifically, the second mounting surface 121 is provided with a receiving groove to allow the mounting component 21 to be embedded in the second mounting surface 121. The heating surface of the heating printhead 22 only slightly protrudes from the second mounting surface 121. Specifically, the protrusion height is 0.1mm to 1mm, which can be any one or any two values of 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm and 1mm.
[0100] More specifically, such as Figure 3 As shown, the first mounting part 11 is a first heat dissipation component; and / or, the second mounting part 12 is a second heat dissipation component; specifically, both the first heat dissipation component and the second heat dissipation component are heat dissipation plates, and heat dissipation fins are provided on the heat dissipation plates; the first heat dissipation component and the second heat dissipation component can also be water-cooled heat dissipation plates or other components with heat dissipation functions; more specifically, the first heat dissipation component and the second heat dissipation component are fixed to the mounting bracket 1 by multiple screws.
[0101] According to an embodiment of this application, in another aspect, a printing device is provided, including the printhead in any of the above embodiments.
[0102] Specifically, the printing device can be a thermal printer or a thermal transfer printer.
[0103] In this implementation, since the printing device includes a printhead and has the same technical effect as the printhead, it will not be described in detail here.
[0104] Although embodiments of this application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and such modifications and variations all fall within the scope defined by the appended claims.
