Description

Technical Field

[0001] This utility model relates to the field of winding equipment technology, and in particular to a convenient winding device for flexographic printing. Background Technology

[0002] A printing press is a machine for printing text and images. A modern printing press generally consists of mechanisms for plate mounting, inking, printing, and paper feeding. Its working principle is as follows: First, the text and images to be printed are made into a printing plate, which is then mounted on the printing press. Then, ink is applied to the areas of the printing plate containing the text and images, either manually or by the printing press itself. The ink is then directly or indirectly transferred to paper or other printing substrates, thereby reproducing a printed product identical to the printing plate.

[0003] A winding device is usually installed on the outside of the printing press. This mechanism can collect and organize the printed materials. During the winding process, the tension rollers often need to be adjusted to accommodate various tension levels and improve winding tightness. In the past, the adjustment method was mostly manual, adjusting the height of multiple tension rollers one by one, which required pausing the winding process. This resulted in time-consuming and labor-intensive adjustment work with low efficiency, thus reducing the overall efficiency of the winding process. The structure needs to be improved. Utility Model Content

[0004] This utility model discloses a convenient rewinding device for flexographic printing. It features a synchronously adjustable tension mechanism, allowing one end of the printed material to pass between two feed rollers, above the first tension roller, and below the second tension roller during operation, before being fixed to the rewinding assembly. The feed rollers feed the material, and the rewinding assembly rewinds it. During this process, the first tension roller, in conjunction with the second tension roller, provides tension to the printed material. If adjustment of the tension provided by the first and second tension rollers is required, a reduction motor can be activated. The reduction motor drives the first lead screw to rotate, and the rotation of the first lead screw, in turn, engages with the leather... The pulley and drive belt drive the second lead screw to rotate synchronously. Since the threads of the first and second lead screws are in opposite directions, the two sliders screwed on the first and second lead screws can move closer to each other or move away from each other. This, in conjunction with four sets of sliding grooves, synchronously drives the first and second tension rollers to move closer to each other or move away from each other, thereby adjusting the tension force provided by the first and second tension rollers to the printed matter. This eliminates the need for manual adjustment and also eliminates the need to pause the winding process of the printed matter, making both the adjustment and winding processes time-saving, labor-saving, and highly efficient. In summary, this solves the problems in the background technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

The sliding seats at both ends of the first and second tension rollers are slidably connected to four sets of sliding grooves via sliding connectors. The first tension roller is located near the feed roller, and the second tension roller is located near the winding assembly. The first and second top seats are fixedly mounted on the top side of one of the mounting seats. The two ends of the first lead screw are respectively... The first and second lead screws are rotatably connected to the bottom of the first top seat and the top of the base, respectively. The two ends of the second lead screw are rotatably connected to the bottom of the second top seat and the top of the base, respectively. The first and second lead screws are both screwed with sliders. One side of each slider passes through two movable slots and is fixedly connected to two slide blocks. The threads of the first and second lead screws are opposite. The first and second lead screws are both fixedly sleeved with pulleys. The two pulleys are connected by a transmission belt. The reduction motor is fixedly installed on the top of the first top seat, and the output end of the reduction motor is connected to the shaft end of the first lead screw.

[0008] An odor adsorption and purification mechanism is located between two mounting bases.

[0009] Furthermore, the first tension roller and the second tension roller are designed to be arranged in an up-down configuration.

[0010] Furthermore, the size of the slider is smaller than the size of the movable groove, and the outside of the slider does not contact the inner wall of the movable groove.

[0011] Furthermore, the odor adsorption and purification mechanism includes a top plate, a purification box, and an exhaust fan. The top plate is fixedly installed between two mounting bases, and the top plate is close to the top of the mounting bases. The purification box and the exhaust fan are both fixedly installed on the top of the top plate. An activated carbon filter plate is movably installed inside the purification box. The exhaust end of the exhaust fan is connected to one side of the purification box, and a duct is connected to the other side of the purification box. One end of the duct is connected to an air collecting hood.

[0012] Furthermore, the top plate is made of aluminum alloy, and the top plate is fixedly connected to the two mounting bases by welding.

[0013] Furthermore, the opening of the air collecting hood is designed at an angle, and the angle of the opening of the air collecting hood is oriented between the first tension roller and the feeding roller.

[0014] Furthermore, a door is hinged to one side of the purification box, and the door is sealed to the purification box when closed.

[0015] The present invention has the following advantages over the prior art:

[0016] 1. This technical solution incorporates a synchronous tension adjustment mechanism, allowing one end of the printed material to pass between two feed rollers, above the first tension roller, and below the second tension roller during operation, before being fixed to the take-up assembly. The feed rollers feed the material, and the take-up assembly takes it back. During this process, the first tension roller, in conjunction with the second tension roller, provides tension to the printed material. If adjustment of the tension provided by the first and second tension rollers is required, the geared motor can be activated. The geared motor drives the first lead screw to rotate, and the rotation of the first lead screw, in conjunction with the tension adjustment mechanism, allows the printed material to be tensioned. The pulley and drive belt drive the second lead screw to rotate synchronously. Since the threads of the first and second lead screws are opposite, the two sliders screwed on the first and second lead screws can move closer to each other or move away from each other. This, in conjunction with four sets of sliding grooves, synchronously drives the first and second tension rollers to move closer to each other or move away from each other, thereby adjusting the tension force provided by the first and second tension rollers to the printed matter. This eliminates the need for manual adjustment and also eliminates the need to stop the winding of the printed matter, making the adjustment and winding work time-saving, labor-saving, and highly efficient.

[0017] 2. This technical solution incorporates an odor adsorption and purification mechanism. During the winding process of printed materials, the exhaust fan, in conjunction with the purification box and duct, generates suction at the air collection hood to draw a large amount of ink odor from the printed materials into the purification box. The activated carbon filter inside the purification box effectively adsorbs and purifies the harmful substances in the odor, finally releasing relatively clean air. This effectively reduces the health hazards to nearby workers and is highly practical. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] In the description of this utility model, it should be understood that the terms "surface", "side", "gap", "peripheral", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Specific Implementation Example 1:

[0028] Reference Figures 1-4 A convenient flexographic printing rewinding device includes a base 1, with two mounting seats 2 fixedly connected to the top of the base 1. Two feeding rollers 3 are rotatably mounted between the two mounting seats 2, and a gear 4 is fixedly connected to one end of each feeding roller 3. The two gears 4 are meshed together. A drive device is externally connected to the shaft end of one of the feeding rollers 3. Two sets of sliding grooves 5 are vertically opened on opposite sides of the two mounting seats 2. Two through movable grooves 6 are opened inside one of the mounting seats 2, located between the two sliding grooves 5 in the same set. The top of the base 1 is fixed... The device is equipped with a winding assembly 7 and a synchronous tensioning mechanism 8, which includes a first tension roller 801, a second tension roller 802, a first top seat 803, a second top seat 804, a first lead screw 805, a second lead screw 806, and a reduction motor 807. The shaft ends of both the first tension roller 801 and the second tension roller 802 are rotatably connected to slide blocks 808, which are U-shaped. The slide blocks 808 at both ends of the first tension roller 801 and the second tension roller 802 are slidably connected to four sets of sliding grooves 5 via sliding connectors. The first tension roller 801 is close to the feeding roller 3, and the second tension roller 802 is close to the winding assembly 7. The first top seat 803 and the second top seat 804 are both fixedly installed on the top side of one of the mounting seats 2. The two ends of the first lead screw 805 are rotatably connected to the bottom of the first top seat 803 and the top of the base 1, respectively. The two ends of the second lead screw 806 are rotatably connected to the bottom of the second top seat 804 and the top of the base 1, respectively. Slider 809s are screwed onto the outside of both the first lead screw 805 and the second lead screw 806. One side of each slider 809... The first lead screw 805 and the second lead screw 806 are fixedly connected to the two movable slots 6 and the two slides 808. The threads of the first lead screw 805 and the second lead screw 806 are opposite. The outer sides of the first lead screw 805 and the second lead screw 806 are fixedly sleeved with pulleys 810. The two pulleys 810 are connected by a transmission belt 811. The reduction motor 807 is fixedly installed on the top of the first top seat 803, and the output end of the reduction motor 807 is connected to the shaft end of the first lead screw 805. The odor adsorption and purification mechanism 9 is located between the two mounting seats 2.

[0029] The first tension roller 801 and the second tension roller 802 are arranged in an up-down configuration; the size of the slider 809 is smaller than the size of the movable groove 6, and the outside of the slider 809 does not contact the inner wall of the movable groove 6.

[0030] In practical implementation, during operation, one end of the printed material can be passed between the two feed rollers 3, above the first tension roller 801, and below the second tension roller 802, and then fixed to the take-up assembly 7. The feed rollers 3 feed the material, and the take-up assembly 7 takes it back. During this process, the first tension roller 801, in conjunction with the second tension roller 802, provides tension to the printed material. If it is necessary to adjust the tension provided by the first tension roller 801 and the second tension roller 802, the reduction motor 807 can be started. The reduction motor 807 drives the first lead screw 805 to rotate, and the rotation of the first lead screw 805, in conjunction with the pulley 810 and the transmission... The belt 811 drives the second lead screw 806 to rotate synchronously. Since the threads of the first lead screw 805 and the second lead screw 806 are opposite, the two sliders 809 screwed on the first lead screw 805 and the second lead screw 806 can move closer to each other or move away from each other in opposite directions. This, in conjunction with the four sets of sliding grooves 5, synchronously drives the first tension roller 801 and the second tension roller 802 to move closer to each other or move away from each other in opposite directions. This adjusts the tension force provided by the first tension roller 801 and the second tension roller 802 to the printed matter. There is no need for manual adjustment, nor is there a need to stop the winding of the printed matter. This makes the adjustment and winding work time-saving, labor-saving, and highly efficient.

[0031] The first tension roller 801 and the second tension roller 802 are designed to be distributed one above the other to ensure that the first tension roller 801 and the second tension roller 802 can provide tension to the printed matter.

[0032] The reason why the outside of the slider 809 does not contact the inner wall of the movable groove 6 is to avoid friction between the slider 809 and the movable groove 6, so as to facilitate the slider 809 to move up and down in the movable groove 6. Specific Implementation Example 2:

[0034] Reference Figure 1 and Figure 5 In a preferred embodiment, the odor adsorption and purification mechanism 9 includes a top plate 901, a purification box 902, and an exhaust fan 903. The top plate 901 is fixedly installed between two mounting bases 2, and the top plate 901 is close to the top of the mounting base 2. The purification box 902 and the exhaust fan 903 are both fixedly installed on the top of the top plate 901. An activated carbon filter plate 904 is movably installed inside the purification box 902. The exhaust end of the exhaust fan 903 is connected to one side of the purification box 902. A duct 905 is connected to the other side of the purification box 902. One end of the duct 905 is connected to an air collecting hood 906.

[0035] The top plate 901 is made of aluminum alloy and is fixedly connected to the two mounting bases 2 by welding. The opening of the air collecting hood 906 is designed at an angle, and the angle of the opening of the air collecting hood 906 faces between the first tension roller 801 and the feeding roller 3. A door 907 is hinged to one side of the purification box 902, and the door 907 is sealed to the purification box 902 when closed.

[0036] In the specific implementation process, during the winding of printed materials, the exhaust fan 903, in conjunction with the purification box 902 and the duct 905, generates suction at the air collection hood 906, drawing a large amount of ink odor from the printed materials into the purification box 902. The activated carbon filter plate 904 inside the purification box 902 effectively adsorbs and purifies the harmful substances in the odor, and finally discharges relatively clean air, which can effectively reduce the health hazards to nearby workers.

[0037] The top plate 901 is made of aluminum alloy to ensure that it has sufficient rigidity and is not easily deformed or damaged. The top plate 901 and the mounting base 2 are fixedly connected by welding to ensure that the connection between the top plate 901 and the mounting base 2 has sufficient strength and is not easily broken or damaged.

[0038] The air collecting cover 906 is oriented between the first tension roller 801 and the feeding roller 3 so that it can better absorb the ink odor on the printed matter.

[0039] The door 907 is sealed to the purification box 902 when closed to ensure the airtightness of the purification box 902 after the door 907 is closed.

[0040] Working principle: During operation, one end of the printed material is passed between the two feed rollers 3, above the first tension roller 801, and below the second tension roller 802, and then fixed to the take-up assembly 7. The feed rollers 3 feed the material, and the take-up assembly 7 takes it back. During this process, the first tension roller 801, in conjunction with the second tension roller 802, provides tension to the printed material. If the tension provided by the first tension roller 801 and the second tension roller 802 needs to be adjusted, the reduction motor 807 can be started. The reduction motor 807 drives the first lead screw 805 to rotate, and the rotation of the first lead screw 805 engages with the pulley 810 and the transmission belt. 811, driving the second lead screw 806 to rotate synchronously. Since the threads of the first lead screw 805 and the second lead screw 806 are opposite, the two sliders 809 screwed on the first lead screw 805 and the second lead screw 806 can move closer to each other or move away from each other in opposite directions. This, in conjunction with the four sets of sliding grooves 5, synchronously drives the first tension roller 801 and the second tension roller 802 to move closer to each other or move away from each other in opposite directions. This adjusts the tension force provided by the first tension roller 801 and the second tension roller 802 to the printed matter. There is no need for manual adjustment, nor is there a need to stop the winding of the printed matter. This makes the adjustment and winding work time-saving, labor-saving, and highly efficient.

[0041] During the winding of printed materials, the exhaust fan 903, in conjunction with the purification box 902 and the duct 905, generates suction at the air collection hood 906, drawing a large amount of ink odor from the printed materials into the purification box 902. The activated carbon filter plate 904 inside the purification box 902 effectively adsorbs and purifies the harmful substances in the odor, finally releasing relatively clean air, which effectively reduces the health hazards to nearby workers.
