[0027] 2D UV printers (UV flatbed printers) require special clamping devices when printing conical rotating bodies. However, the special clamping devices have complex structures and high manufacturing costs. Moreover, the special clamping devices only support the printing of conical rotating bodies with fixed tapers. For the printing of conical rotating bodies with different tapers, different specifications of clamping fixtures need to be replaced. The compatibility is poor, the operation is complicated, and the adjustment cycle is long. It is not conducive to the use of novice users and the user experience is poor, resulting in the low popularity of UV flatbed printers.

[0028] See also Figure 1 and Figure 2 The embodiment of the present application provides a print support fixture 100. The print support fixture 100 includes a base 30 and a first support mechanism 10 and a second support mechanism 20 arranged on the base 30; the first support mechanism 10 includes a rotation drive assembly 101, and the rotation drive assembly 101 includes a rotating support member 1010; the second support mechanism 20 includes a lifting assembly 1 and a rolling support assembly 2, the lifting assembly 1 is used to drive the rolling support assembly 2 to move up and down, and the rolling support assembly 2 includes at least two driven supports 21 arranged at intervals along a first direction; the first direction is perpendicular to the lifting direction; the rotating support member 1010 and the driven support member 21 can cooperate to support the rotating print, and the rotating support member 1010 is used to drive the rotating print to rotate.

[0029] like Figure 1 and Figure 2 As shown in , the X direction is the first direction, the Y direction is the second direction, the Z direction is the lifting direction, and the X direction, the Y direction and the Z direction are perpendicular to each other.

[0030] The rotary drive assembly 101 includes at least one set of rotating support members 1010, and the rotating support members 1010 are used to support and drive the rotating body printing member to rotate. The rolling support assembly 2 is used to support the rotating body printing member, so that the rotating body printing member can be rotatably supported on the second support mechanism 20, so as to print the rotating body printing member. The rolling support assembly 2 is arranged on the lifting assembly 1. When the lifting assembly 1 is raised, the rolling support assembly 2 is driven to rise; when the lifting assembly 1 is lowered, the rolling support assembly 2 is driven to lower; thereby, the support height of the rolling support assembly 2 is adjusted by the lifting and lowering movement of the lifting assembly 1. The rotating support member 1010 and the driven support member 21 can cooperate to support the rotating body printing member, for example, the rotating body printing member can include a tapered rotating body, a cylinder or a cone, etc.

[0031] like Figure 1 As shown in the figure, the print support fixture 100 can be used to support the print of the conical rotating body 2000 for printing; when in use, the print of the conical rotating body 2000 with a taper is placed on the first support mechanism 10 and the second support mechanism 20, the rolling support component 2 of the second support mechanism 20 is adjusted and raised by the lifting component 1, and the level 3000 is used to adjust the conical surface of the conical rotating body 2000 with a taper to a horizontal state, and the rotation drive component 101 of the first support mechanism 10 provides power to drive the conical rotating body 2000 to rotate, thereby realizing printing on the surface of the conical rotating body 2000.

[0032] like Figure 2 As shown in the figure, the print support fixture 100 can also be used to support the step cylinder 4000 print for printing, that is, it is compatible with the printing of the step cylinder 4000 print with a large front end and a small rear end; when in use, the step cylinder 4000 print is placed on the first support mechanism 10 and the second support mechanism 20, the rolling support component 2 is adjusted and raised by the lifting component 1 to support the rear end of the step cylinder 4000 print, and the rotating drive component 101 supports the front end of the step cylinder 4000 print and provides power to drive the step cylinder 4000 to rotate, thereby realizing printing on the surface of the step cylinder 4000.

[0033] By setting up two groups of driven support members 21, stable support can be provided for cylindrical printed parts of different lengths, printing is stable, and printing effect is improved. There is no need to adjust the position of the second support mechanism 20 in the first direction, which reduces user operations and is conducive to printing of rotating bodies of different length specifications, with strong compatibility.

[0034] The print support fixture 100 of the embodiment of the present application can be arranged at the bottom of the printer to rotatably support the rotating body print; by setting the second support mechanism 20 including the lifting component 1, the lifting and lowering adjustment of the support height of the second support mechanism 20 can be realized, so that the conical surface of the conical rotating body 2000 with different tapers can be adjusted to a horizontal state, which is compatible with the printing of conical rotating bodies 2000 with different tapers, and can also be compatible with the printing of stepped cylinders 4000; at the same time, by setting the rolling support component 2 including at least two groups of driven supports 21, the support stability of longer prints can be improved, the printing is stable, the printing effect is improved, and it is conducive to the printing of rotating bodies of different length specifications; thus, the print support fixture 100 can be compatible with rotating body prints of different tapers and lengths, has strong compatibility, and is simple and convenient to use, reduces manual operation, improves user experience, and is conducive to the promotion and popularization of UV flatbed printers.

[0035] In some embodiments, see Figure 1 and Figure 2 The rotating support member 1010 includes two active rollers 1011 spaced apart from each other along the second direction. And / or, refer to Figures 1 to 5 The driven support member 21 includes two driven rollers 211 spaced apart along a second direction, wherein the second direction is perpendicular to both the first direction and the lifting direction.

[0036] The two active rollers 1011 spaced apart along the second direction can contact the outer peripheral surface of the rotating printed part; for example, the active roller 1011 can be a rubber-coated roller, and the friction generated between the rubber-coated roller and the surface of the rotating printed part is used to drive the rotating printed part to rotate. In some embodiments, the first support mechanism 10 also includes a drive motor 103 and a transmission assembly 104, and the output shaft of the drive motor 103 is connected to the active roller 1011 through the transmission assembly 104, and the active roller 1011 is driven to rotate by the drive motor 103; for example, the transmission assembly 104 can include a transmission belt, etc.

[0037] The two driven rollers 211 spaced apart along the second direction can roll in contact with the outer peripheral surface of the rotating printed part, so that the rotating printed part can be rotatably supported on the second support mechanism 20, and at this time, the central axis of the rotating printed part is perpendicular to the second direction. For example, the driven roller 211 can be a rubber-coated roller, and the rubber-coated structure can increase the friction between the rotating printed part and the driven roller 211, so as to prevent the rotating printed part and the driven roller 211 from slipping.

[0038] In some embodiments, see Figures 3 to 5The lifting assembly 1 includes a driving member 11 and at least one group of support rods 12, the support rod group 12 includes two support rods 121 that are crossed and rotatably connected, the driving member 11 is connected to at least one support rod 121, and the driving member 11 is used to drive the same ends of the two support rods 121 to move closer to or away from each other so that the top end of the support rod group 12 is raised or lowered; the rolling support assembly 2 is arranged at the top end of the support rod group 12.

[0039] For example, the two support rods 121 of the support rod group 12 can be cross-hinged through the hinge shaft 122, and the two support rods 121 can be cross-installed in a scissor-fork manner, and the two support rods 121 can flexibly rotate around the hinge shaft 122, so that the support rod group 12 forms a scissor-fork structure; the driving member 11 drives the same end of the two support rods 121 of the support rod group 12, such as the bottom ends approaching each other, so that the top of the support rod group 12 can be raised; the driving member 11 drives the bottom ends of the two support rods 121 of the support rod group 12 away from each other, so that the top of the support rod group 12 can be lowered. Thus, the lifting assembly 1 forms an X-shaped scissor-fork lifting structure.

[0040] The rolling support assembly 2 is arranged at the top of the support rod group 12. When the top of the support rod group 12 rises, the rolling support assembly 2 rises; when the top of the support rod group 12 falls, the rolling support assembly 2 falls; thus, the second support mechanism 20 forms a scissor seat type support structure that can be raised and lowered. Figure 3 As shown in , the second support mechanism 20 is in a raised state; Figure 4 As shown in FIG. 1 , the second supporting mechanism 20 is in a lowered state.

[0041] By setting the second support mechanism 20 to form a scissor seat type liftable support structure, the support height can be lifted and lowered. The print support fixture 100 has a simple and compact structure, high space utilization, reduced occupied space, and low manufacturing cost. It is also simple and convenient to use, reduces manual operation, and improves user experience.

[0042] In some embodiments, see Figures 3 to 6 The lifting assembly 1 includes two support rod groups 12, and the two support rod groups 12 are arranged at intervals along a direction parallel to the rotation axis of the support rod 121.

[0043] For example, the rotation axis of the support rod 121 is parallel to the first direction. By providing two groups of support rod groups 12, the lifting assembly 1 forms a double X-shaped scissor-type lifting structure, which has a greater bearing capacity and more stable lifting.

[0044] In some embodiments, see Figures 3 to 6The lifting assembly 1 also includes a fixing member 13 and a first connecting member 14, the first connecting member 14 is rotatably connected to the bottom end of at least one supporting rod 121, and the driving member 11 includes a driving screw rod 111, the driving screw rod 111 is rotatably penetrated on the fixing member 13, and the driving screw rod 111 is threadedly connected to the first connecting member 14.

[0045] For example, the first connecting member 14 can be a connecting shaft, one end (top end) of the support rod 121 is connected to the rolling support assembly 2, and the other end maintains freedom, and the free ends (bottom ends) of the support rods 121 of the two support rod groups 12 are connected by a connecting shaft; this is conducive to improving the synchronization of the movements of the two support rod groups 12.

[0046] For example, the driving member 11 further includes a driving knob 112, which is connected to one end of the driving screw 111 away from the first connecting member 14. By operating the driving knob 112, the driving screw 111 can be driven to rotate, and the driving screw 111 drives the first connecting member 14 threaded thereon to move along the driving screw 111, and the first connecting member 14 drives the bottom end of the supporting rod 121 to move along the driving screw 111, so that the bottom ends of the two supporting rods 121 move closer to or away from each other, thereby realizing the lifting movement of the lifting assembly 1.

[0047] By setting the driving part 11 to adopt a screw rod and a nut mechanical structure, the lifting movement of the lifting component 1 is realized. In conjunction with the level 3000, the taper can be adjusted steplessly, and the screw rod has a self-locking feature, which can realize the self-locking suspension of the rolling support component 2 at any height position, making the lifting more stable, and the use is simple and convenient, reducing manual operation and improving user experience.

[0048] In some embodiments, see Figures 1 to 5 as well as Figure 7 The rolling support assembly 2 also includes a first mounting member 22, and the driven support member 21 is arranged on the first mounting member 22; the top end of a support rod 121 of the support rod group 12 is rotatably connected to the first mounting member 22, and the top end of the other support rod 121 is slidably abutted against the first mounting member 22.

[0049] The specific shape of the first mounting member 22 is not limited, for example, it can be a mounting plate or a mounting block, etc. The driven roller 211 is rotatably disposed on the first mounting member 22. By making the top end of the support rod 121 slidably abut against the first mounting member 22, it is beneficial to provide more stable support, more stable lifting, stable printing, and improved printing effect.

[0050] In some embodiments, see Figure 7The rolling support assembly 2 also includes a rotating shaft 25, which passes through the opposite sides of the first mounting member 22. The two ends of the rotating shaft 25 are respectively connected to the driven roller 211 through driven bearings 212, so that the rolling support assembly 2 forms a symmetrical structure at both ends, and the force stability is better. The driven bearing 212 can reduce the friction between the driven roller 211 and the first mounting member 22, so that the driving motor 103 outputs a smaller torque, which can drive the rotating body printing part to rotate together with the driven roller 211 to achieve stable printing.

[0051] In some embodiments, see Figures 3 to 5 The rolling support assembly 2 also includes a limit member 23, which is connected to the first mounting member 22 and forms a guide portion 24 with the first mounting member 22, and the guide portion 24 extends along the first direction; the lifting assembly 1 also includes a second connecting member 15, which is connected to the top end of at least one support rod 121, and the second connecting member 15 is slidably connected to the guide portion 24.

[0052] The stopper 23 can be a sheet metal part or a composite material part, which is not limited here. For example, the stopper 23 can be a sheet metal part in the shape of an inverted "X", and both ends of the stopper 23 are fixedly connected to the first mounting part 22, and the stopper 23 and the first mounting part 22 surround a long strip through hole, namely the guide part 24.

[0053] For example, the second connecting member 15 can be a connecting shaft, one end (bottom end) of the support rod 121 is fixed and the other end remains free, and the free ends (top ends) of the support rods 121 of the two support rod groups 12 are connected by a connecting shaft; this is conducive to improving the synchronization of the movements of the two support rod groups 12.

[0054] The second connecting member 15 is movably arranged in the guide portion 24 and can slide along the guide portion 24. In this way, the sliding movement of the top end of the support rod 121 on the first mounting member 22 can be guided and limited, the lifting movement of the lifting assembly 1 is more stable, the use is simple and convenient, manual operation is reduced, and the user experience is improved.

[0055] In some embodiments, see Figure 1 and Figure 2 The base 30 includes a support member 301 extending along a first direction; the first support mechanism 10 is disposed on the support member 301; and the second support mechanism 20 is slidably disposed on the support member 301.

[0056] For example, the first support mechanism 10 also includes a mounting seat 102, and the rotation drive assembly 101, the drive motor 103 and the transmission assembly 104 are all arranged on the mounting seat 102. The first support mechanism 10 is fixedly arranged at one end of the support member 301 through the mounting seat 102; the second support mechanism 20 can slide along the support member 301, so that the spacing distance between the first support mechanism 10 and the second support mechanism 20 can be adjusted along the first direction. In this way, by adjusting the spacing distance between the first support mechanism 10 and the second support mechanism 20, the print support fixture 100 can adapt to rotating prints of different lengths, with stronger compatibility, simple and convenient use, improved user experience, and conducive to the promotion and popularization of UV flatbed printers.

[0057] In some embodiments, see Figure 1 and Figure 2 , the support member 301 has a support surface 3011; see Figures 1 to 5 as well as Figure 8 The second supporting mechanism 20 also includes an installation component 3, which includes a second installation member 31. The bottom side of the second installation member 31 can be slidably supported on the supporting surface 3011 so that the installation component 3 can be slidably installed on the supporting member 301; the lifting component 1 is installed on the top side of the second installation member 31.

[0058] For example, the support surface 3011 is the top surface of the support member 301, and the support surface 3011 is parallel to the horizontal plane. The specific shape of the second mounting member 31 is not limited, for example, it can be a mounting plate or a mounting block. The second mounting member 31 slides on the support surface 3011, so that the mounting assembly 3 slides along the support member 301, so that the mounting assembly 3 is slidably mounted on the support member 301; the mounting assembly 3 slides along the support member 301, driving the second support mechanism 20 to slide along the support member 301. For example, the fixing member 13 of the lifting assembly 1 is fixedly connected to the top side of the second mounting member 31.

[0059] By providing the mounting assembly 3 , the second supporting mechanism 20 is slidably connected to the base 30 , so that the second supporting mechanism 20 is slidably arranged on the supporting member 301 .

[0060] In some embodiments, see Figures 3 to 5 The bottom end of one support rod 121 of the support rod group 12 is rotatably connected to the second mounting member 31, and the bottom end of the other support rod 121 is slidably abutted against the second mounting member 31. By making the bottom end of the support rod 121 slidably abut against the second mounting member 31, it is beneficial to provide more stable support, more stable lifting, stable printing, and improved printing effect.

[0061] In some embodiments, see Figures 3 to 6The lifting assembly 1 also includes a fixed connecting member 16, and the support rod group 12 also includes a rolling member 123, for example, the rolling member 123 can be a bearing; the top end of a support rod 121 in the support rod group 12 is rotatably connected to a fixed connecting member 16, and the fixed connecting member 16 is fixedly connected to the first mounting member 22, and the bottom end of the support rod 121 maintains freedom, and a rolling member 123 is connected to the free end, and abuts against the second mounting member 31 through the rolling member 123; the bottom end of another support rod 121 in the support rod group 12 is rotatably connected to another fixed connecting member 16, and the other fixed connecting member 16 is fixedly connected to the second mounting member 31, and the top end of the other support rod 121 maintains freedom, and a rolling member 123 is connected to the free end, and abuts against the first mounting member 22 through the other rolling member 123.

[0062] In some embodiments, see Figures 3 to 5 The lifting assembly 1 also includes a support block 17, which is fixedly mounted on the second mounting member 31; when the second supporting mechanism 20 is in a lowered state, the support block 17 and the fixing member 13 support the first mounting member 22, and the support is more stable.

[0063] In some embodiments, see Figure 1 and Figure 2 The base 30 further includes a guide member 302, which is disposed on at least one side of the support member 301 adjacent to the support surface 3011 and parallel to the first direction, and the guide member 302 extends along the first direction. Figures 1 to 5 as well as Figure 8 The mounting assembly 3 further includes a sliding limiter 32 , which is disposed on the bottom side of the second mounting member 31 . The sliding limiter 32 is movably connected to the guide member 302 and can move along the guide member 302 .

[0064] The guide member 302 is disposed on at least one side of the support member 301 along the second direction; the sliding limit member 32 moves along the guide member 302 to drive the installation assembly 3 to slide along the extension direction of the guide member 302 .

[0065] In this way, the sliding limit member 32 plays a limiting and guiding role in the sliding movement of the installation component 3 on the support member 301, thereby realizing the guiding and limiting of the sliding movement of the second support mechanism 20. The second support mechanism 20 slides stably and reliably along the support member 301, and the adjustment of the spacing distance between the first support mechanism 10 and the second support mechanism 20 is more accurate and stable. It is simple and convenient to use, reduces manual operation, and improves user experience.

[0066] In some embodiments, see Figures 3 to 5 as well as Figure 8The sliding limit member 32 includes a first limit roller 321 and a second limit roller 322, the rotation axes of the first limit roller 321 and the second limit roller 322 are parallel to the lifting movement direction, and the first limit roller 321 and the second limit roller 322 are spaced apart along the second direction.

[0067] Guide members 302 are provided on opposite sides of the support member 301 along the second direction. The first limiting roller 321 is connected to the guide member 302 on one side of the support member 301 by rolling cooperation, and the second limiting roller 322 is connected to the guide member 302 on the other side of the support member 301 by rolling cooperation, thereby limiting the relative position of the installation component 3 and the base 30 in the second direction.

[0068] For example, the guide member 302 may be an optical axis protruding from the side of the support member 301, and the optical axis may have an arc-shaped cross-section; correspondingly, the first limiting roller 321 and the second limiting roller 322 may be U-shaped bearings having an annular U-shaped groove on the outer circumference. When the mounting assembly 3 is assembled on the base 30, the annular U-shaped groove of the U-shaped bearing matches the arc surface of the optical axis to achieve the limiting guiding function.

[0069] In this way, the second support mechanism 20 is limited in the second direction, and the stability of the connection between the installation component 3 and the base 30 is improved. At the same time, by adopting a rolling fit connection, there is rolling friction between the sliding limit member 32 and the guide member 302, and the friction force is smaller. The second support mechanism 20 slides along the support member 301 more smoothly, and it is simpler and more convenient to adjust the spacing distance between the first support mechanism 10 and the second support mechanism 20, thereby improving the user experience.

[0070] In some embodiments, see Figures 1 to 5 as well as Figure 8 The sliding limiter 32 includes two second limit rollers 322 , and the two second limit rollers 322 are arranged at intervals along the first direction. This is beneficial to improving the stability of the second support mechanism 20 sliding along the support member 301 .

[0071] In some embodiments, see Figure 8 The sliding limiting member 32 further includes an eccentric member 323 , the first limiting roller 321 is connected to the eccentric member 323 , and the eccentric member 323 is rotatably connected to the second mounting member 31 .

[0072] The eccentric member 323 refers to a part whose rotation axis is offset relative to the central axis. For example, the eccentric member 323 may be an eccentric nut; it also includes a half-thread stud 324 and a lock nut 325; the half-thread stud 324 is sequentially inserted through the first limiting roller 321, the eccentric nut and the second mounting member 31, and is threadedly fastened with the lock nut 325, so that the first limiting roller 321 is rotatably mounted on the second mounting member 31; at the same time, the second limiting roller 322 is also rotatably mounted on the second mounting member 31 through the half-thread stud 324 and the lock nut 325. When the eccentric member 323 is rotated, the first limiting roller 321 can be driven to deviate a distance in a direction perpendicular to the rotation axis of the eccentric member 323, so that the first limiting roller 321 can move relatively close to or away from the second limiting roller 322, so as to adjust the spacing between the first limiting roller 321 and the second limiting roller 322, thereby adjusting the tightness of the first limiting roller 321 and the second limiting roller 322 clamping the guide member 302. In this way, it is beneficial to improve the stability of the connection between the mounting assembly 3 and the base 30, and it is not easy to loosen and fall off, and the second support mechanism 20 slides more stably along the support member 301, which is simple and convenient to use, and improves the user experience.

[0073] See also Fig. 9 The embodiment of the present application provides a nozzle printer 1000, including a frame 300, a print head 200 and a print support fixture 100 provided in any of the above embodiments; the print support fixture 100 is detachably fixedly mounted on the frame 300; the print head 200 can be slidably disposed on the frame 300, and the print head 200 is disposed above the print support fixture 100.

[0074] For example, the base 30 of the print support fixture 100 can be detachably fixedly connected to the frame 300 by fasteners such as bolts; or, the frame 300 has a sliding connection structure such as a slide rail or a slide groove, and the base 30 of the print support fixture 100 is slidably and detachably connected to the frame 300 by the sliding connection structure. In this way, the print support fixture 100 can be replaced as a whole in the print head printer 1000 to be compatible with the printing of different types of prints, further improving the compatibility of the print head printer 1000 and facilitating its use.

[0075] For example, the sliding direction of the print head 200 is parallel to the first direction; when the print piece is supported on the print piece support fixture 100, the nozzle of the print head 200 faces the print piece; the print head 200 is used to spray liquid ink onto the print piece, thereby printing the print piece.

[0076] Since the nozzle printer 1000 has the same technical effect as the above-mentioned print support fixture 100, it will not be described in detail here.

[0077] In some embodiments, see Fig. 9 The nozzle printer 1000 also includes a crossbeam 400 and a shell 500 . A printing space 501 for UV printing a rotating printed part is formed inside the shell 500 . The printed part support fixture 100 , the print nozzle 200 , the frame 300 and the crossbeam 400 are all arranged in the printing space 501 .

[0078] For example, the frame 300 is fixedly arranged in the printing space 501; the print support fixture 100 is arranged on the frame 300 and is located at the bottom of the printing space 501; the beam 400 is arranged on the frame 300 and is located above the print support fixture 100, and the beam 400 extends along the first direction; the print head 200 is slidably arranged on the beam 400, so that the print head 200 can be slidably arranged above the print support fixture 100.

[0079] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0080] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
