[0045] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

Therefore, they should not be construed as limitations on this application.

[0047] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0048] like Figure 1-2As shown, a digital printing machine transfer assembly according to a preferred embodiment of the present invention includes a frame 1, a work platform 2 mounted on the frame 1, and a nozzle 3 movably mounted on the frame 1. The nozzle 3 is used to spray transfer varnish. Specifically, the frame 1 is provided with a crossbeam, which can move relative to the frame 1 in the Y-axis direction; the nozzle 3 is mounted on the crossbeam and can move relative to the crossbeam in the X-axis direction. One end of the work platform 2 is provided with an unwinding mechanism 4, and both sides and the other end of the work platform 2 are provided with film clamping and tensioning mechanisms 5. A film cutting mechanism 6 is provided between the work platform 2 and the unwinding mechanism 4, and a film suction mechanism 7 is provided between the film cutting mechanism 6 and the unwinding mechanism 4. The assembly also includes a transfer roller a, which is mounted on the frame 1 via a lifting and moving mechanism 8. A film feeding mechanism 9 is provided on the bearing seat 84 of the transfer roller a, and a heating tube is provided at the center of the transfer roller a.

[0049] Based on the above-mentioned technical features, the digital printing machine transfer assembly has an unwinding mechanism 4 at one end of the working platform 2, and film clamping and tensioning mechanisms 5 on both sides and the other end of the working platform 2. The unwinding mechanism 4 tightens one side of the transfer film, and the film clamping and tensioning mechanisms 5 tighten the other three sides of the transfer film, so that all four sides of the transfer film can be tightened, ensuring that the transfer film covers the substrate smoothly and thus ensuring product quality.

[0050] like Figure 3-5 In this embodiment, the membrane clamping and tensioning mechanism 5 includes a clamping mechanism 54 and a first driving mechanism. The clamping mechanism 54 includes a clamping seat 541 and a second driving mechanism disposed on the clamping seat 541. The clamping seat 541 includes a clamping wall, and a clamping block 542 is provided inside the clamping seat 541. The second driving mechanism is used to drive the clamping block 542 to move toward or away from the clamping wall. The first driving mechanism is used to drive the clamping mechanism 54 to move up and down; or to drive the clamping mechanism 54 to move toward or away from the working platform 2.

[0051] By providing a clamping wall on the clamping seat 541, and a clamping block 542 inside the clamping seat 541, the second driving mechanism drives the clamping block 542 to move towards or away from the clamping wall. After the transfer film is delivered between the clamping wall and the clamping block 542, the second driving mechanism drives the clamping block 542 to move towards the clamping wall, thereby clamping the transfer film. Then, the first driving mechanism drives the clamping mechanism 54 to move up and down; or drives the clamping mechanism 54 to move towards or away from the working platform 52, thereby achieving tensioning of the transfer film. At the same time, since the film clamping and tensioning mechanism 5 is located at the end or side of the working platform 2, all four sides of the transfer film can be tensioned, ensuring that the transfer film covers the substrate flatly, thereby ensuring product quality.

[0052] In this embodiment, the film clamping and tensioning mechanism 5 includes a mounting bracket 55 for connecting to the frame 1, facilitating installation. The first driving mechanism is a tensioning cylinder 56, the cylinder of which is connected to the mounting bracket 55, and the telescopic rod of which is connected to the clamping mechanism 54. When the tensioning cylinder 56 is activated, it drives the clamping mechanism 54 to move up and down or away from the working platform 2, thereby tightening the transfer film.

[0053] Specifically, the mounting frame 55 includes a support portion and a connecting portion for connecting to the frame 1. The support portion is perpendicular to the connecting portion, and a support tube 57 is provided at the other end of the support portion corresponding to the clamping block 542. That is, when the transfer film is tightened, the edge of the transfer film is supported on the support tube 57, preventing the transfer film from breaking during the tightening process. In addition, a support tube is also provided between the working platform 2 and the film cutting mechanism 6 to ensure that all four sides of the transfer film are supported on the support tube.

[0054] In this embodiment, if the clamping mechanism 54 achieves tension by moving up and down during tensioning, the tensioning cylinder 56 is disposed at the connecting part; if the clamping mechanism 54 achieves tension by moving laterally during tensioning, the tensioning cylinder 56 is disposed at the supporting part. Alternatively, the mounting bracket 55 can also be formed by splicing two mounting bracket bodies, both of which are L-shaped. The tensioning cylinder 56 is disposed on one of the mounting bracket bodies, and the clamping mechanism 54 and the limit switch 58 are disposed on the other mounting bracket body (e.g., ...). Figure 4 (As shown).

[0055] Meanwhile, the mounting bracket 55 is equipped with a limit switch 58 for detecting the travel of the clamping mechanism 54. When feeding the film, the film clamping and tensioning mechanism 5 needs to move upward to ensure that the transfer film can be accurately fed between the clamping block 542 and the clamping wall. After clamping the transfer film, the clamping mechanism 54 needs to move to achieve tensioning of the transfer film. By setting the limit switch 58, the travel of the clamping mechanism 54 can be monitored in real time to ensure the smooth operation of the work.

[0056] In this embodiment, the clamping seat 541 includes a clamping plate 5411, a fourth fixing plate 5412, and a connecting plate 5413 connecting one end of the clamping plate 5411 and the fourth fixing plate 5412, with the clamping plate 5411 located directly above the fourth fixing plate 5412. The inner wall of the clamping plate 5411 is the clamping wall. The first driving mechanism is connected to either the fourth fixing plate 5412 or the connecting plate 5413. Specifically, if the clamping mechanism 54 achieves tension by moving up and down during tensioning, the tensioning cylinder 56 is connected to the fourth fixing plate 5412. This is mainly used when the clamping tensioning mechanism is located on both sides of the working platform 2. If the clamping mechanism 54 achieves tension by moving laterally during tensioning, the tensioning cylinder 56 is connected to the connecting plate 5413. Of course, when the clamping mechanism 54 is tightened, it is achieved by moving up and down. The tensioning cylinder 56 can also be connected to the connecting plate 5413. However, a connecting seat 5c is also required. The first driving mechanism and the clamping seat 541 are connected through the connecting seat 5c. This is mainly used when the clamping tensioning mechanism 5 is located at the end of the working platform 2 (e.g., Figure 4 (As shown).

[0057] In this embodiment, the second driving mechanism is a driving cylinder 59. The cylinder of the driving cylinder 59 is connected to the outer wall of the fourth fixed plate 5412, and the telescopic rod of the driving cylinder 59 passes through the fourth fixed plate 5412 and is connected to the clamping block 542.

[0058] In this embodiment, a first protective film 5a is laid on the clamping wall, and a second protective film 5b is provided on the side of the clamping block 542 opposite to the first protective film 5a. That is, when the transfer film is clamped, the transfer film is located between the first protective film 5a and the second protective film 5b, which avoids damage to the transfer film and ensures the transfer effect.

[0059] like Figure 6-7 As shown, the unwinding mechanism 4 includes a mounting plate 41, an unwinding roller 42, a rack 43, a first lifting mechanism and a push-pull mechanism mounted on the mounting plate 41, which is mounted on the frame 1. The unwinding roller 42 includes a connecting part 421 and a supporting part 422 for mounting the roll material. The connecting part 421 is rotatably mounted on the mounting plate 41, and a first gear 44 is provided on the connecting part 421. The first lifting mechanism and the push-pull mechanism are both connected to the rack 43. The first lifting mechanism is used to drive the rack 43 to move up and down, and the push-pull mechanism is used to drive the rack 43 to engage or disengage with the first gear 44. The unwinding roller 42 can directly use an unwinding air shaft, or the supporting part can use an unwinding air shaft, to ensure the tension of the roll material.

[0060] The unwinding mechanism 4 rotatably mounts the connecting part 421 of the unwinding roller 42 onto the mounting plate 41. A first gear 44 is mounted on the connecting part 421, and both the first lifting mechanism and the push-pull mechanism are connected to a rack 43. During unwinding, the push-pull mechanism drives the rack 43 to disengage from the first gear 44, ensuring normal rotation and unwinding of the unwinding roller 42. When tensioning is required, the push-pull mechanism pushes the rack 43 to mesh with the first gear 44, while the first lifting cylinder 4b drives the rack 43 to rotate, causing the transfer film to tighten. When the transfer film is fully tightened, both the push-pull mechanism and the first lifting mechanism stop moving, and the unwinding roller 42 cannot rotate, effectively ensuring the tension of the transfer film during the transfer process and guaranteeing product quality. After the transfer is completed, both the first lifting mechanism and the push-pull mechanism move in opposite directions, separating the first gear 44 from the rack 43, and the unwinding roller 42 resumes its unwinding function.

[0061] In this embodiment, two bearing seats 45 are provided opposite each other on the mounting plate 41. Each bearing seat 45 contains a bearing, and the connecting part 421 connects the two bearings, thereby ensuring the rotation of the connecting part 421. Simultaneously, to prevent the connecting part 421 from detaching from the bearing seat 45, a fixing ring 46 is provided at the end of the connecting part 421 away from the supporting part 422. The fixing ring 46 abuts against the outer wall of the bearing seat 45 away from the supporting part 422. The connecting part 421 and the supporting part 422 are coaxially arranged, and the supporting part 422 has a larger diameter. Therefore, the end of the supporting part 422 connected to the connecting part 421 abuts against the outer wall of the other bearing seat 45. Thus, under the action of the fixing ring 46 and the supporting part 422, the connecting part 421 is completely confined between the two bearing seats 45, preventing the unwinding roller 42 from separating from the bearing seat 45.

[0062] Specifically, the fixing ring 46 abuts against the steel sleeve, and the steel sleeve abuts against the inner ring of the bearing in the bearing housing, so that the unwinding roller 42 is limited and will not move back and forth during rotation.

[0063] In this embodiment, the rack 43 is provided with a drive plate 47, and the drive plate 47 has a drive hole 471 extending vertically, that is, the drive hole 471 is waist-shaped and arranged vertically. The first lifting mechanism is connected to the lower end of the drive plate 47, and the push-pull mechanism is connected to the drive hole 471. That is, the push-pull mechanism does not move in the vertical direction. When the first lifting mechanism drives the drive plate 47 to move the rack 43 up and down, the push-pull mechanism will not interfere with the up and down movement of the rack 43 because it is connected to the drive hole 471. When the push-pull mechanism needs to drive the rack 43 to move, the push-pull mechanism pushes and pulls the inner wall of the drive hole 471, so that the rack 43 moves along the width direction of the drive hole 471.

[0064] In this embodiment, the first lifting mechanism is a first lifting cylinder 4b. The cylinder barrel of the first lifting cylinder 4b is connected to the mounting plate 41, and the telescopic rod of the first lifting cylinder 4b is connected to the drive plate 47. Specifically, the mounting plate 41 is provided with a mounting hole, and a first mounting seat 48 is provided in the mounting hole. The cylinder barrel of the first lifting cylinder 4b is connected to the first mounting seat 48, and the telescopic rod of the first lifting cylinder 4b passes through the mounting hole and connects to the drive plate 47.

[0065] In this embodiment, the push-pull mechanism is a push-pull cylinder 4c. The cylinder barrel of the push-pull cylinder 4c is connected to the mounting plate 41. A push-pull shaft 49 is connected to the telescopic rod of the push-pull cylinder 4c. The push-pull shaft 49 is inserted into the drive hole 471, and the axis of the push-pull shaft 49 is perpendicular to the extension direction of the drive hole 471. The push-pull shaft 49 pushes the rack 43 to move. In specific installation, a seat plate is connected to the telescopic rod of the push-pull cylinder 4c. Connecting rods are respectively provided at both ends of the other side of the seat plate, and the two ends of the push-pull shaft 49 are respectively connected to the connecting rods. At the same time, a second mounting seat 4a is provided on one side of the mounting plate 41, and the cylinder barrel of the push-pull cylinder 4c is fixed on the second mounting seat 4a.

[0066] like Figure 8-9 As shown, in this embodiment, the film cutting mechanism 6 includes a second lifting mechanism disposed opposite to both sides of the frame 1. The second lifting mechanism is provided with a heating wire fixing seat 62, and a heating wire 66 is connected between the two heating wire fixing seats 62. The two ends of the heating wire 66 are connected to a power source for heating. The heating wire fixing seat 62 is also provided with a tensioning mechanism for tightening the heating wire 66.

[0067] The film cutting mechanism 6 of the present invention includes a second lifting mechanism on both sides of the frame 1, a heating wire fixing seat 62 on the second lifting mechanism, and a heating wire 66 connected between the two heating wire fixing seats 62. A tensioning mechanism for tightening the heating wire 66 is also provided on the heating wire fixing seat 62. After installation, the heating wire 66 is kept horizontally taut under the action of the tensioning mechanism. When cutting the film, the heating wire 66 is heated first, and then the second lifting mechanism moves the heating wire 66 upward to cut the transfer film. Since the heating wire melting and cutting method is used, the transfer film will not tear during the cutting process, ensuring a neat cut and avoiding waste caused by unevenly cut transfer film, thus ensuring transfer efficiency.

[0068] In this embodiment, the second lifting mechanism is preferably a second lifting cylinder 61. The cylinder of the second lifting cylinder 61 is connected to the frame 1, and the telescopic rod of the second lifting cylinder 61 is connected to the heating wire fixing seat 62. The heating wire fixing seat 62 includes a connecting rod 63 and a fixing rod 64 that are perpendicularly connected. The other end of the connecting rod 63 is connected to the second lifting mechanism, the heating wire 66 is connected to the other end of the fixing rod 64, and the tensioning mechanism is disposed on the fixing rod 64.

[0069] Specifically, the fixing rod 64 is provided with mounting holes 641, and the heating wire 66 passes through the mounting holes 641. Simultaneously, one end of the fixing rod 64 connected to the connecting rod 63 is provided with a connecting seat, and the heating wire 66 is fixed by the connecting seat after passing through the two mounting holes 641. The tensioning mechanism is a tension spring 65, one end of which is connected to the fixing rod 64, and the other end is connected to the heating wire 66. During installation, both ends of the heating wire 66 pass through the mounting holes 641 respectively, are then fixed to the connecting seat, and then both ends are connected to a power source. Finally, the tension spring 65 is connected.

[0070] In this embodiment, the connecting rod 63 includes a first connecting portion 631 and a second connecting portion 632. The width of the first connecting portion 631 is greater than the width of the second connecting portion 632, and the thickness of the first connecting portion 631 is less than the thickness of the second connecting portion 632. The second lifting mechanism is connected to the lower surface of the first connecting portion 631. The larger width of the first connecting portion 631 ensures the stability of the connection. The other end of the second connecting portion 632 is connected to the fixing rod 64 and has the same thickness as the fixing rod 64, ensuring the aesthetics of the connection. Simultaneously, the smaller width of the second connecting portion 632 reduces the overall weight.

[0071] like Figure 10-12 As shown, in this embodiment, the film feeding mechanism 9 is mounted on the bearing seats 84 of the transfer roller a, and is mounted on both bearing seats 84. The transfer roller a can move laterally. The film feeding mechanism 9 includes a clamping mechanism, a connecting plate 93, and a fourth lifting mechanism mounted on the bearing seats 84. The connecting plate 93 includes a driving end and a film clamping end. The driving end is connected to the fourth lifting mechanism. The film clamping end is provided with a cooperating first clamp 94 and a second clamp 95. The clamping mechanism is used to drive the second clamp 95 to move toward or away from the first clamp 94.

[0072] The film feeding mechanism 9 of this invention is mounted on the bearing seat 84 of the transfer roller a, allowing the transfer roller a to move laterally. A connecting plate 93 is mounted on the bearing seat 84 and connected via a fourth lifting mechanism. A first clamp 94 and a second clamp 95 are fitted at the other end of the connecting plate 93. A clamping mechanism drives the second clamp 95 to move towards or away from the first clamp 94. When film feeding is required, the two sides of one end of the transfer film are placed between the corresponding first clamp 94 and second clamp 95. Then, the clamping mechanism drives the second clamp 95 towards the first clamp 94 to clamp the transfer film. The film feeding mechanism then moves with the transfer roller a away from the unwinding mechanism until the transfer film completely covers the substrate, thus achieving automatic film feeding. Furthermore, because both sides of one end of the transfer film are clamped simultaneously during film feeding, uniform force is ensured on both sides of the transfer film, preventing wrinkling during feeding and guaranteeing the transfer effect.

[0073] Once the transfer film completely covers the substrate, the film clamping mechanism 5 clamps the transfer film, and then the first chuck 94 and the second chuck 95 of the film feeding mechanism 9 release the transfer film, and the transfer roller a performs the transfer.

[0074] In this embodiment, the fourth lifting mechanism is a third lifting cylinder 96. The cylinder barrel of the third lifting cylinder 96 is connected to the bearing seat 984, and the telescopic rod of the third lifting cylinder 96 is connected to the drive end. Specifically, a first fixing plate 97 is connected to the telescopic rod of the third lifting cylinder 96, and a second fixing plate 9a is connected to the drive end. The first fixing plate 97 and the second fixing plate 9a are bolted together. This connection method between the first fixing plate 97 and the second fixing plate 9a increases the connection area between the third lifting cylinder 96 and the connecting plate 93, ensuring the stability of the connection. The second fixing plate 9a and the connecting plate 93 can also be integrally formed.

[0075] In this embodiment, the clamping mechanism is a clamping cylinder 98. The cylinder barrel of the clamping cylinder 98 is connected to the connecting plate 93, and the telescopic rod of the clamping cylinder 98 is connected to the second clamp 95. Specifically, the clamping end is provided with a mounting groove 931, and a third fixing plate 99 is provided on one side of the mounting groove 931. The cylinder barrel of the clamping cylinder 98 is connected to the mounting groove 931, and the first clamp 94 is connected to the third fixing plate 99. The first clamp 94 is L-shaped and includes a connecting part 941 and a clamping part 942. The connecting part 941 is connected to the third fixing plate 99, and the clamping part 942 cooperates with the second clamp 95 to clamp the transfer film.

[0076] like Figure 13As shown, the film suction mechanism 7 is mounted on the frame 1 and located between the unwinding mechanism 4 and the film cutting mechanism 6. It includes a third lifting mechanism that is disposed opposite to each other on both sides of the frame 1. The third lifting mechanism is provided with a suction cup fixing seat 72, and the suction cup fixing seat 72 is provided with a suction cup 75 for adsorbing the transfer film.

[0077] The film suction mechanism 7 is positioned between the unwinding mechanism 4 and the film cutting mechanism 6. It also includes a third lifting mechanism with a suction cup fixing seat 72. The suction cup fixing seat 72 has a suction cup 75 for adsorbing the transfer film. When the transfer is completed and film cutting is required, the third lifting mechanism drives the suction cup 75 to move upward and hold the transfer film. At the same time, under the action of the film clamping and tightening mechanism, the film to be cut is fully tightened in the vertical direction, preventing the transfer film from falling at the film cutting mechanism position, ensuring smooth film cutting, and avoiding waste caused by cutting unused transfer film.

[0078] After the cutting is completed, the suction cup 75 detaches from the transfer film and descends under the action of the third lifting mechanism.

[0079] In this embodiment, the third lifting mechanism is preferably a fourth lifting cylinder 71. The cylinder barrel of the fourth lifting cylinder 71 is connected to the frame 1, and the telescopic rod of the fourth lifting cylinder 71 is connected to the suction cup fixing seat 72. Meanwhile, to facilitate the connection between the fourth lifting cylinder 71 and the frame 1, a cylinder fixing seat 73 can be provided on the frame 1, and the cylinder barrel of the fourth lifting cylinder 71 can be directly connected to the cylinder fixing seat 73.

[0080] In this embodiment, to further clamp the transfer film and improve the film cutting effect, a support tube 74 is connected between the two suction cup fixing seats 72. That is, the two suction cups 75 adsorb the edges of the transfer film, and the support tube 74 supports the middle of the transfer film, thereby preventing the transfer film from sagging between the two suction cups 75 and further ensuring the clamping effect, thus improving the film cutting effect. At the same time, to prevent the support tube 75 from damaging the surface of the transfer film, the support tube 75 includes a support surface. The support surface is horizontal. Specifically, the support tube 75 can be set as a square column, simply made of square tubing, with the upper surface of the square tubing serving as the support surface. This method is simple and convenient. Alternatively, the support surface can be set as an arc shape, directly made of round tubing.

[0081] In this embodiment, the suction cup mounting base 72 includes a connecting rod 721 and a mounting rod 722. One end of the connecting rod 721 is connected to the fourth lifting cylinder 71, and the other end of the connecting rod 721 is connected to the support tube 74. One end of the mounting rod 722 is connected to the middle of one side of the connecting rod 721, that is, the connecting rod 721 and the mounting rod 722 form a T-shape. The suction cup 75 is disposed on the upper surface of the other end of the mounting rod 722.

[0082] like Figure 13-14 As shown, in this embodiment, the lifting and moving mechanism 8 includes two rack guide rails 81 symmetrically arranged on both sides of the frame 1, and two drive components arranged in a one-to-one correspondence with the two rack guide rails 81;

[0083] The drive assembly includes a mounting frame 82, on which a lead screw 83 and a first power mechanism for driving the lead screw 83 to rotate are mounted. A bearing seat 84 is connected to the upper end of the lead screw 83, and a transfer roller a is connected between the two bearing seats 84. The rotation of the lead screw 83 is driven by the first power mechanism, thereby raising and lowering the transfer roller a. The mounting frame 82 also has a second gear 86 that meshes with the rack and pinion guide rail 81. The second gear 86 is driven to rotate by the second power mechanism, thereby moving the second gear 86 along the rack and pinion guide rail 81, thereby translating the transfer roller a.

[0084] The lifting and moving mechanism 8 of the present invention uses a lead screw 83 connected to bearing seats 84 on the mounting frame 82 of the drive assembly. A transfer roller a is connected between the two bearing seats 84. The lifting and lowering of the transfer roller a is achieved by the rotation of the lead screw 83. Due to the high precision of the lead screw 83, the stability of the lifting and lowering of the transfer roller a is ensured. Simultaneously, a second gear 86 meshing with a rack and pinion guide rail 81 is provided on the mounting frame 82. The second gear 86 is driven to rotate by a second motor mechanism. Since the two rack and pinion guide rails 81 are symmetrically arranged on both sides of the frame 1, and the two drive assemblies are correspondingly arranged one-to-one with the two rack and pinion guide rails 81, the symmetry of the driving force at both ends of the transfer roller a is ensured, and the two ends of the transfer roller a will always move synchronously. Furthermore, since the transfer roller a moves along the rack and pinion guide rail 81 during its movement, no positional deviation occurs during its movement, thus effectively ensuring the stability of the transfer roller a's movement and guaranteeing the transfer effect.

[0085] In this embodiment, the rack guide rail 81 includes a plane and a toothed surface arranged opposite to each other, with the toothed surface located below the plane. A slider 87 is provided on the mounting bracket 28, and the slider 87 slides against the plane. The second gear 86 is located inside the slider 87. When the second gear 86 rotates, it moves along the rack guide rail 81, and the slider 87 drives the mounting bracket 82 to move, thereby realizing the movement of the transfer roller a. To ensure the stability of the movement, multiple second gears 86 can be provided inside the slider 87, such as two second gears 86 at the front and two at the back of the slider 87. All second gears 86 are rotatably connected to the side wall of the slider 87, and one of the second gears 86 is connected to the second power mechanism.

[0086] In this embodiment, to further ensure the stability of the transfer roller a's movement, the slider 87 is provided with a groove extending to both ends. The groove is fitted onto the rack guide rail 81, and the upper inner wall of the groove slides against the plane. When the second gear 86 moves along the tooth surface of the rack guide rail 81, the groove slides along the plane of the rack guide rail 81, ensuring the overall stability of the slider 87's movement. Simultaneously, a limiting strip 88 is provided on the plane, and the slider 87 is provided with a limiting groove communicating with the groove. The two sides of the limiting strip 88 are in contact with the two inner walls of the limiting groove. That is, when the slider 87 slides along the plane, it is also limited by the limiting strip 88, ensuring that the slider 87 can only move along the length direction of the rack guide rail 81. Thus, with the cooperation of the second gear 86 and the rack guide rail 81, combined with the effects of the groove and the limiting strip, the overall movement of the mounting frame 82 has good stability, effectively ensuring the transfer effect of the product.

[0087] Please see the appendix Figure 15In this embodiment, the first power mechanism includes a first driving pulley 812 and a first driven pulley 813 rotatably connected to the mounting bracket 82. A first belt connects the first driving pulley 812 and the first driven pulley 813. The first driving pulley 812 is connected to a first motor 814, and the first driven pulley 813 is connected to the lead screw 83. That is, the first motor 814 drives the first driving pulley 812 to rotate, the first driving pulley 812 drives the first driven pulley 813 to rotate via the first belt, and the first driven pulley 813 drives the lead screw 83 to rotate. Specifically, a worm gear 815 is connected to the center of the first driven pulley 813, and a rotating drum 816 is threaded onto the lead screw 83. The rotating drum 816 is provided with a turbine 817 that cooperates with the worm gear 815. When the first passive pulley 813 rotates, it drives the worm gear 815 to rotate, and the worm gear 815 drives the rotating drum 816 to rotate. Since the rotating drum 816 is threadedly connected to the lead screw 83 and the rotating drum 816 does not move up and down, the lead screw 83 rises and falls, thereby realizing the lifting and lowering movement of the transfer roller a driven by the bearing seat 84.

[0088] In addition, to ensure the stability and accuracy of the movement of the bearing housing 84, guide cylinders 821 are respectively provided on both sides of the lead screw 83 on the mounting bracket 82. Guide rods 822 are inserted into the guide cylinders 821, and the upper ends of the guide rods 822 are connected to the bearing housing 84. That is, the lead screw 83 is positioned between the two guide rods 822, and the lifting and lowering of the lead screw 83 is guided by the guide rods 822, ensuring the stability and accuracy of the lead screw 83 driving the bearing housing 84 to lift and lower.

[0089] In this embodiment, the second power mechanism includes a second driving pulley 818 and a second driven pulley 819 rotatably connected to the mounting bracket 82. A second belt connects the second driving pulley 818 and the second driven pulley 819. The second driving pulley 818 is connected to a second motor 820, and the second driven pulley 819 is connected to a second gear 86 via a connecting shaft. The rotation of the second motor 820 drives the second driving pulley 818 to rotate, which in turn drives the second driven pulley 819 to rotate via the second belt. The second driven pulley 819 then drives the second gear 86 to rotate.

[0090] Furthermore, to integrate the two drive components into a single unit and further improve the stability of the transfer roller a's movement, connecting rods 89 are connected between the two first motors 814 and between the two second motors 820. To ensure the stability of the connecting rods 89 themselves, a connecting frame 810 is connected between the two mounting brackets 82. The connecting frame 810 has connecting ears 811, and the middle portion of the connecting rod 89 is connected to the connecting ears 811, thus forming a single unit at the lower ends of the two drive components. The upper ends of the two drive components are connected via the transfer roller a, further enhancing the stability of the transfer roller a's movement.

[0091] For ease of description, the present invention defines the film clamping and tensioning mechanism 5 located at one end of the working platform 2 as the left film clamping and tensioning mechanism, and the film clamping and tensioning mechanisms 5 on both sides of the working platform 2 as the front film clamping and tensioning mechanism and the rear film clamping and tensioning mechanism, respectively. Here, left, front, and rear are all based on the attached... Figure 1 The orientation is defined.

[0092] The working process of the digital printing press transfer component is as follows:

[0093] 1. After the marble beam is coated with varnish by spraying varnish through nozzle 3, it will be... Figure 1 The middle crossbeam Y-axis moving mechanism is driven to move to the rear of the Y-axis. The front clamping film tensioning mechanism, the rear clamping film tensioning mechanism, and the left clamping film tensioning mechanism are driven by cylinders to rise above the surface of the substrate, and the clamping mechanism 54 opens; 2. The transfer roller a is driven by Figure 1The lifting mechanism of the transfer (heat transfer, hot stamping) lifting and moving mechanism shown in the figure is raised to the highest point. Then, the lifting cylinder of the film feeding mechanism 9, which is fixed on the bearing seat 84 of the transfer roller a, lowers the chuck of the film feeding mechanism 9 to the lowest point and opens the chuck. 3. The film of the transfer film roll is placed between the chucks of the film feeding mechanism 9 and the chucks are clamped. 4. The film feeding mechanism 9, which is lowered to the lowest point and clamping the film, and the transfer roller a, which is raised to the highest point, are moved by the moving mechanism of the lifting and moving mechanism 8 (which is composed of a gear rack guide rail, a motor-driven pulley, and the pulley drives the gear to move along the X-axis of the rack) to send the film from the right side of the machine to the clamping mechanism 54 of the film clamping and tightening mechanism on the left side. At the same time, the two sides of the film enter the clamping machines of the front clamping and tightening mechanism and the rear clamping and tightening mechanism, respectively. Within mechanism 54, after the transfer (heat transfer, hot stamping) lifting and moving mechanism delivers the film to the clamping mechanism 54 of the front, rear, and left side film clamping and tightening mechanism, the front, rear, and left side film clamping and tightening mechanism 54 clamps the film. At the same time, the chuck of the film feeding mechanism 9 releases and moves a distance to the left along the transfer roller a until the center of the transfer roller a corresponds to the center of the four-sided film support tube 57 on the left side of the machine. Then, the front, rear, and left side film clamping and tightening mechanisms descend simultaneously, and the unwinding mechanism 4 on the right side of the machine causes the transfer and hot stamping roll to rotate backward and tighten the film. After this action is completed, the film will cover the surface of the substrate very flat due to the support of the four-sided film support tube 57. 5. After the previous step is completed, the lifting mechanism 9, which is fixed on the transfer roller bearing seat 84, lifts... The cylinder raises the chuck, and then the lifting and moving mechanism 8 lowers the transfer roller a along with the film feeding mechanism 9 to the working surface to press the film; 6. The lifting and moving mechanism 8 then moves the transfer roller a from the left side of the X-axis to the right side to complete the product transfer (heat transfer, hot stamping); 7. After the transfer roller a completes the transfer (heat transfer, hot stamping), it needs to be raised to the highest point. Then, the front clamping and tightening mechanism, the rear clamping and tightening mechanism, and the left clamping and tightening mechanism simultaneously rise to the highest point. At this time, the front, rear, and left clamping and tightening mechanisms are at their highest points, but the clamping mechanism 54 is still in the clamping state. At the same time, the unwinding mechanism 4 is also released, and the film suction mechanism 7 rises. The suction cups 75 on both sides of the film suction mechanism 7 suck up the film, and the support tube 74 in the middle supports the film to prevent it from sagging in the middle. 8. After the film suction mechanism 7 suctions the film, the heating wire cutting mechanism 6 lifts and lowers to cut the film. After the heating wire cuts the film, it returns to its original position. At this time, the lifting cylinder of the film feeding mechanism 9, which has risen to the highest point, lowers the chuck to the lowest point. Then, the lifting and moving mechanism 8 drives the transfer roller a, connected to the film feeding mechanism 9, to move a distance to the right of the X-axis until the film enters the open chuck of the film feeding mechanism 9. Then the chuck clamps, the suction cup 75 of the film suction mechanism 7 releases, and the film suction mechanism 7 returns to the original point. Then, the lifting and moving mechanism 8 moves the transfer roller a, connected to the film feeding mechanism 9, to the right of the X-axis to the original point. When it reaches the original point, the transfer roller a returns to the original point, and at the same time, the lifting cylinder of the film feeding mechanism 9, which is clamping the film, raises the chuck to the highest point.9. At this point, the clamping mechanisms 54 of the front, rear, and left side film clamping and tightening mechanisms open. After the transferred film is removed, the front, rear, and left side film clamping and tightening mechanisms lower to the origin (below the working plane) and remove the transferred (heat transfer, hot stamping) product or proceed to the next process; 10. At this point, the product transfer (heat transfer, hot stamping) is completed; 11. When transferring (heat transfer, hot stamping) the second batch of products, the front, rear, and left side film clamping and tightening mechanisms rise to their highest point, clamping mechanism 54 is open, and then the transfer roller a, along with the film feeding mechanism 9, rises to its highest point. The lifting cylinder of the film feeding mechanism 9 lowers the clamping head of the film to its lowest point, and the lifting and moving mechanism 8 begins to move to the left of the X-axis to feed the film back into the clamps of the front, rear, and left side film clamping and tightening mechanisms. The process is the same as in 4-10 to complete the transfer (heat transfer, hot stamping), and this is a cyclical process.

[0094] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
