The invention is further described with reference to the following figures and specific embodiments.
As shown in fig. 1 and 2, the drying device for a printing apparatus of the present embodiment includes:
a conveyor belt 10;
a drying box 20 arranged on the upper side of the conveyor belt 10, wherein an opening 21 is arranged on the bottom plate of the drying box 20, a fan 22 is further arranged on the drying box 20, and when the drying box is operated, airflow (shown by an arrow A in figure 3) blown towards the opening 21 on the bottom plate of the drying box 20 is generated and then blown to the surface of the printed matter conveyed on the conveyor belt 10, so that the printing ink is dried;
a left pinch roller 30-a and a right pinch roller 30-b which are arranged at the lower side of the bottom plate of the drying box 20.
During drying, referring to the view direction shown in fig. 1, the printed matter is conveyed into a drying box 20 from the rear on a conveying belt 10, left and right pinch rollers 30-a and 30-b are pressed on the printed matter in a pressure-sharing manner, the fan 22 works to generate air flow to blow the printed matter, dry the ink, and finally output from the front to finish drying. In the process, the pressing wheel is pressed on the printed matter, so that the printed matter is not easily blown to deform and keeps a flat state, the pressing wheel also rotates simultaneously, and the printed matter, the pressing wheel and the conveying belt do not slide relatively, so that scratches are not easily generated, and the conveying of the printed matter is not influenced.
In order to adapt to printed matters with different specifications, the left bracket 40-a and the right bracket 40-b are preferably provided in the embodiment, the left pinch roller 30-a is rotatably connected to the left bracket 40-a, and the right pinch roller 30-b is rotatably fixed on the right bracket 40-b. At least one of the left bracket 40-a or the right bracket 40-b is also in transmission connection with a transmission mechanism, and the transmission mechanism can drive the brackets to move, so as to adjust the positions of the left and right pinch rollers 30-a and 30-b and change the distance between the left and right pinch rollers.
Preferably, the transmission mechanism is a bidirectional screw rod 50, which is rotatably fixed on the upper side of the bottom plate of the drying box 20. For example, a mounting seat 52 is fixed on the bottom plate 20, and a sleeve hole (not shown) is formed in the middle of the mounting seat and is rotatably sleeved on the outer side of the bidirectional screw rod 50 through the sleeve hole. A strip-shaped hole 23 is arranged on the bottom plate of the drying box 20 below the bidirectional screw rod 50 so as to allow the left bracket 40-a and the right bracket 40-b to pass through and be connected with the bidirectional screw rod 50, and the left bracket and the right bracket can horizontally move along the strip-shaped hole 23.
The upper part of the left bracket 40-a is provided with a screw hole which passes through the strip-shaped hole 23 and is sleeved outside the left part of the bidirectional screw rod 50; the upper part of the right bracket 40-b is also provided with a screw hole which passes through the strip-shaped hole 23 and is sleeved outside the right part of the bidirectional screw rod 50.
The strip-shaped holes 23 play a limiting role: with the bidirectional screw 50 as a reference, the left and right brackets 40-a, 40-b are limited around the circumference of the bidirectional screw 50 and cannot rotate around the bidirectional screw 50, and the screw thread fit between the brackets and the screw only retains the degree of freedom along the axial direction of the bidirectional screw 50. Therefore, the left and right brackets 40-a and 50-b can be driven to approach or separate from each other by rotating the bidirectional screw rod 50, so as to realize the adjustment of the distance between the two brackets.
Obviously, the present invention is not limited to other ways to adjust the distance between the left and right brackets 40-a, 50-b. For example, each support is driven by one lead screw, the left support is in threaded sleeve joint with one left lead screw, and the right support is in threaded sleeve joint with one right lead screw. Or, each bracket is separately connected with a push rod or an electric push rod, and one push rod correspondingly drives one bracket to move, so that the distance adjustment can be realized.
Further, the bidirectional screw rod 50 is in transmission connection with a motor 51, and the motor 51 is controlled to operate to adjust the distance between the left and right pinch rollers 30-a and 30-b, so that automatic control is realized, and the operation is more accurate and faster.
Preferably, the motor 51 is a stepping motor or a servo motor, and the bidirectional screw rod 50 is in transmission connection with the motor 51 through a coupling (not shown in the figure), so that more stable transmission is realized.
Referring to fig. 3, preferably, two pairs of left and right pinch rollers 30-a and 30-b arranged in a front-back manner, i.e. two pinch rollers on the left side and two pinch rollers on the right side, are arranged on the lower side of the drying oven 20 to form four pinch points, and the pinch points are pressed on the left and right side edges of the printed matter, so that the printed matter can be better prevented from being blown up.
Furthermore, the two right pinch rollers 30-a and 30-b are provided with a right synchronous belt 31, and the two left pinch rollers 30-a are provided with a left synchronous belt (not shown in the figure, but basically the same as the right synchronous belt 31 and different in position), wherein the pinch rollers themselves are not directly pressed on the printed matter, but the synchronous belts are pressed on the printed matter, so that the two side edges of the printed matter are pressed, the printed matter is fully prevented from being blown, the drying effect is greatly improved, and in addition, the synchronous belts themselves have certain elasticity, and the press marks are not easy to leave on the printed matter.
Furthermore, a link rod 41 is fixed on each of the left bracket 40-a and the right bracket 40-b, and a guide mechanism 42 is fixedly connected to the inner side of the link rod 41, and is used for accurately guiding and moving the printed matter to a position below the pinch rollers, so that the pinch rollers accurately press the two side edges of the printed matter. As shown in fig. 4, the guide mechanism 42 may be an arc-shaped shifting piece tilted forward, and the lower end surface of the guide mechanism 42 is close to the conveyer belt 10, and the distance between the lower end surface and the conveyer belt is small but not in frictional contact, preferably not exceeding the thickness of the printed matter; the guide mechanism 42 may also be a guide wheel (not shown) or other structure with equivalent function.
