For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0023] like Figure 1-2 As shown in Figures 5 and 6, a film clamping and tensioning mechanism of a digital printing machine in a preferred embodiment of the utility model is arranged at the end or side of the working platform 1. Specifically, when the digital printing machine has a reeling mechanism 2 and a reeling mechanism 3, the film clamping and tensioning mechanism of the digital printing machine only needs to be arranged on both sides of the working platform 1, and together with the reeling mechanism 2 and the reeling mechanism 3, a four-side tensioning mechanism is formed (such as Figure 3 , 4 As shown); when the digital printing machine is not provided with an unwinding mechanism 3, the film clamping and tensioning mechanism of the digital printing machine needs to be arranged on both sides of the working platform 1 and at the end opposite to the unwinding mechanism 2, so as to form tension on the four sides of the transfer film. The film clamping and tensioning mechanism of the digital printing machine includes a clamping mechanism 4 and a first driving mechanism, the clamping mechanism 4 includes a clamping seat 41 and a second driving mechanism arranged on the clamping seat 41, the clamping seat 41 includes a clamping wall, a clamping block 42 is arranged inside the clamping seat 41, the second driving mechanism is used to drive the clamping block 42 to move toward or away from the clamping wall, and the first driving mechanism is used to drive the clamping mechanism 4 to move up and down (as shown in FIG. Figure 3 or drive the clamping mechanism 4 to move toward or away from the working platform 1 (as shown); Figure 4 shown).
[0024] The film clamping and tensioning mechanism of the digital printing machine based on the above technical features is provided with a clamping wall on the clamping seat 41, and a clamping block 42 is provided inside the clamping seat 41. The second driving mechanism drives the clamping block 42 to move toward or away from the clamping wall. After the transfer film is sent between the clamping wall and the clamping block 42, the second driving mechanism drives the clamping block 42 to move toward the clamping wall to clamp the transfer film, and then the first driving mechanism drives the clamping mechanism 4 to move up and down; or drives the clamping mechanism 4 to move toward or away from the working platform 1, so as to tighten the transfer film; at the same time, since the film clamping and tensioning mechanism of the digital printing machine is arranged at the end or side of the working platform 1, the four sides of the transfer film can be tightened, ensuring that the transfer film covers the substrate evenly, thereby ensuring product quality.
[0025] In this embodiment, the film clamping and tensioning mechanism of the digital printing machine includes a mounting frame 5 for connecting to the printing machine frame, which is convenient for installation. The first driving mechanism is a tensioning cylinder 6, the cylinder barrel of the tensioning cylinder 6 is connected to the mounting frame 5, and the telescopic rod of the tensioning cylinder 6 is connected to the clamping mechanism 4. When the tensioning cylinder 6 is started, the clamping mechanism 4 is driven to move up and down or move away from the working platform 1 to achieve the tensioning of the transfer film.
[0026] Specifically, the mounting frame 5 includes a supporting portion and a connecting portion for connecting to a frame, the supporting portion is arranged perpendicularly to the connecting portion, and the other end of the supporting portion is provided with a supporting hose 7 corresponding to the clamping block 42. That is, when the transfer film is tightened, the edge of the transfer film is supported on the supporting hose 7, thereby preventing the transfer film from breaking during the tightening process. If the clamping mechanism 4 is tightened by moving up and down during tightening, the tensioning cylinder 6 is arranged at the connecting portion; if the clamping mechanism 4 is tightened by moving laterally during tightening, the tensioning cylinder 6 is arranged at the supporting portion. In addition, the mounting frame can also be formed by splicing two mounting frame bodies, both of which are L-shaped, wherein the tensioning cylinder 6 is arranged on one of the mounting frame bodies, and the clamping mechanism 4 and the travel switch 8 are arranged on the other mounting frame body (such as Figure 2 shown).
[0027] At the same time, a travel switch 8 for detecting the stroke of the clamping mechanism 4 is provided on the mounting frame 5. When feeding the film, the film clamping and tensioning mechanism of the digital printing machine needs to move up to ensure that the transfer film can be accurately fed between the clamping block 42 and the clamping wall. After clamping the transfer film, the clamping mechanism 4 needs to move to tighten the transfer film. By setting the travel switch 8, the stroke of the clamping mechanism 4 can be monitored in real time to ensure the smooth progress of the work.
[0028] In this embodiment, the clamping seat 41 includes a clamping plate 411, a fixed plate 412, and a connecting plate 413 that connects the clamping plate 411 and one end of the fixed plate 412, and the clamping plate 411 is located directly above the fixed plate 412, the inner wall of the clamping plate 411 is the clamping wall, and the first driving mechanism is connected to the fixed plate 412 or the connecting plate 413. Specifically, if the clamping mechanism 4 is tightened by moving up and down during tightening, the tensioning cylinder 6 is connected to the fixed plate 412. This situation is mainly used in the case where the clamping film tensioning mechanism of the digital printing machine is arranged on both sides of the working platform 1. If the clamping mechanism 4 is tightened by moving horizontally during tightening, the tensioning cylinder 6 is connected to the connecting plate 413. Of course, the clamping mechanism 4 is tightened by moving up and down. The tensioning cylinder 6 can also be connected to the connecting plate 413, but a connecting seat c is required. The first driving mechanism and the clamping seat 41 are connected through the connecting seat c. This situation is mainly used in the case where the clamping film tensioning mechanism of the digital printing machine is arranged at the end of the working platform 1 (such as Figure 2 shown).
[0029] In this embodiment, the second driving mechanism is a driving cylinder 9 , a cylinder barrel of the driving cylinder 9 is connected to the outer wall of the fixing plate 412 , and a telescopic rod of the driving cylinder 9 passes through the fixing plate 412 to connect to the clamping block 42 .
[0030] In this embodiment, a first protective film a is laid on the clamping wall, and a second protective film b is provided on the side of the clamping block 42 facing the first protective film a, that is, when the transfer film is clamped, the transfer film is located between the first protective film a and the second protective film b, thereby avoiding damage to the transfer film and ensuring the transfer effect.
[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
