Description

Technical Field

[0001] The invention relates to the technical field of corrugated rollers, in particular to a vacuum adsorption corrugated roller. Background Art

[0002] The corrugating roller is an important key part of the single-sided machine. The corrugating roller is divided into an upper corrugating roller and a lower corrugating roller. Both the upper and lower roller surfaces are female. The two rollers are paired and meshed. The meshing mechanism is different from the usual gear transmission. The lower corrugating roller is the active roller, and a gear is installed on the shaft end. The motor drives the lower corrugating roller to rotate through a reduction device, and the upper corrugating roller is the driven roller. The teeth of the upper roller and the teeth of the lower roller are meshed with each other for transmission. In order to make the corrugated paper corrugated between the upper and lower corrugated rollers, a certain pressure must be applied to the upper corrugated roller. Therefore, in addition to rotating around its own axis, the upper corrugated roller can also move along the line connecting the axes of the upper and lower corrugated rollers. This movement is achieved by applying radial pressure to both ends of the upper corrugated roller through the cylinder, so that the meshing corrugated rollers generate biting pressure.

[0003] The existing corrugating roller has an inconvenient gap between the upper and lower rollers, which makes it impossible to achieve specific and appropriate embossing of corrugated paper of different thicknesses. After the gap between the corrugating rollers becomes easier to adjust, how to maintain the continuous pressure of the upper roller on the lower roller is also a problem that needs to be solved. Therefore, the present invention proposes a vacuum adsorption corrugating roller to solve the problems raised in the above background technology. Summary of the invention

A chute corresponding to the slider II is formed on the outer side of the support seat. A second clamping block is rotatably connected to the slider II. A second rotating rod is fixed between the two left and right clamping blocks II on the same side;

[0009] After the vertical adjustment of the extrusion block is achieved by adjusting the rotating sleeve, the adjusting rotating sleeve is rotated flat into the corresponding card slot on the sliding seat. Then, the inserting rod passes through the corresponding through holes on the diagonal support and the sliding seat. The nut on one end of the inserting rod is screwed tightly, and the nut is made to closely adhere to the outer side surface of the sliding seat, so that the diagonal support is fixedly connected to the sliding seat.

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Refer to Figures 1-5 , a vacuum adsorption corrugating roll, including a machine base 1, support bases 4 are installed at both left and right ends of the machine base 1, a driving roller 2 is installed below the middle of the left and right support bases 4, a driven roller 3 is arranged above the driving roller 2, sliding seats 5 are arranged at both ends of the driven roller 3, bearing seats 7 are installed at both ends of the driven roller 3, the two bearing seats 7 are respectively located in the two side sliding seats 5, the outer sides of the upper ends of the sliding seats 5 are rotatably connected to inclined supports 6, the lower ends of both sides of the inclined supports 6 are rotatably connected to first sliders 19, a first rotating rod 18 is rotatably connected between the two left and right first sliders 19, a first clamping block 15 is fixed at the center of the first rotating rod 18, side support bars 14 are rotatably connected to both sides of the middle of the inclined supports 6, second sliders 20 are rotatably connected to the outer sides of the side support bars 14, a second clamping block 17 is rotatably connected to the second slider 20, a second rotating rod 21 is fixed between the two left and right second clamping blocks 17 on the same side. When it is necessary to adjust the gap between the upper and lower rollers, rotate the two first rotating rods 18 and the second rotating rod 21. The rotating first rotating rod 18 drives the first clamping block 15 fixed at the center to rotate, and at the same time, the second rotating rod 21 drives the second clamping blocks 17 fixed at both ends to rotate;

[0026] Furthermore, the slide 5 slides up and down in the corresponding support seat 4, and a sliding groove corresponding to the slider 20 is provided on the outside of the support seat 4, and a torsion spring is provided at the transition between the rotating rod 21 and the sliders 20 on both sides. A sliding groove corresponding to the slider 19 is provided on both sides of the surface of the machine base 1, and a torsion spring is provided at the transition between the rotating rod 18 and the sliders 19 on both sides. A slot 16 corresponding to the block 15 is provided on the left and right sides of the machine base 1, and a slot 22 corresponding to the block 2 17 is provided on the left and right sides of the outside of the support seat 4, so that the blocks 2 17 at both ends are disengaged from the corresponding slots 22 on both sides, and the rotating block 15 is disengaged from the lower slot 16, so that the angles of the oblique supports 6 on both sides can be adjusted, thereby adjusting the upper position of the inner end slide 5. When the angle of the inclined support 6 is increased, the height of the slide seats 5 on both sides becomes higher, and the gap between the upper and lower rollers becomes larger. When the angle of the inclined support 6 is decreased, the height of the slide seats 5 on both sides becomes lower, and the gap between the upper and lower rollers becomes smaller. At the same time, as the height and angle of the upper end of the inclined support 6 are adjusted, the acute angle between the inner side support strips 14 of the inclined support 6 on both sides and the inclined support 6 also increases or decreases accordingly. After determining the gap distance between the upper and lower rollers, the rotating rods 18 and 21 on both sides are released. The rotating rods are acted upon by the torsion springs at the transition parts, wherein the clamping block 15 and the clamping blocks 2 17 at both ends are clamped into the corresponding groove positions. At this time, the angle of the inclined support 6 cannot be adjusted up or down, thereby achieving the purpose of fixing the upper and lower positions of the slide seats 5 on both sides.

[0027] Furthermore, two slide bars 8 passing through the bearing seat 7 are fixed in the slide seat 5, and the bearing seat 7 slides up and down in the slide seat 5 through the slide bars 8 on both sides. A screw rod 9 connected to the slide seat 5 is provided between the left and right slide bars 8. The upper end of the screw rod 9 is threadedly connected to an extrusion block 11, and the extrusion block 11 slides up and down between the slide bars 8 on both sides. A spring 10 is provided around the slide bar 8 and is located between the extrusion block 11 and the lower bearing seat 7. As the gap between the upper and lower rollers changes, the pressure of the driven roller 3 between the slide seats 5 on the lower active roller 2 will increase or decrease. In order to ensure that the driven roller 3 has a continuous and stable pressure on the lower active roller 2 after adjustment, Adjust the compression degree of the springs 10 in the slides 5 on both sides, and then adjust the pressure on the lower active roller 2. The rotation adjustment of the screw 9 is achieved through the adjusting sleeve 12 connected to the upper end of the screw 9. As the screw 9 rotates, the extrusion block 11 threadedly connected to it slides up and down between the slide bars 8 on both sides. When the extrusion block 11 slides down, the shorter the lower spring 10 is compressed, the tighter the pressure on the lower bearing seat 7 is, that is, the stronger the pressure of the driven roller 3 on the lower active roller 2 is. This adjustment is applicable to the adjustment behavior after the driven roller 3 is raised. When the gap between the upper and lower rollers becomes smaller, the progress of the spring 10 is appropriately adjusted, and the height of the extrusion blocks 11 on both sides can be adjusted upward.

[0028] Furthermore, the upper end of the screw rod 9 is rotatably connected with an adjusting sleeve 12. A clamping groove corresponding to the adjusting sleeve 12 is formed on the upper side of the sliding seat 5. A plug rod 13 penetrates through the outer end of the adjusting sleeve 12. One end of the plug rod 13 is fixed with a stud, and a nut sleeve tightly attached to the outer side of the sliding seat 5 is threadedly connected to the stud. The other end of the plug rod 13 is fixed with a limiting block. After the upper and lower adjustment of the extrusion block 11 is realized through the adjusting sleeve 12, the adjusting sleeve 12 is rotated flat into the corresponding clamping groove on the sliding seat 5, and then the plug rod 13 is passed through the inclined support 6 and the corresponding through hole on the sliding seat 5. The nut sleeve on the stud at one end of the plug rod 13 is tightened, and the nut sleeve is tightly attached to the outer side surface of the sliding seat 5, so that the inclined support 6 is fixedly connected with the sliding seat 5.

[0029] The specific working principle of the present invention is as follows:

[0030] When using this vacuum adsorption corrugated roll, when it is necessary to adjust the gap between the upper and lower rolls, rotate the two side rotating rods one 18 and the rotating rod two 21. The rotating rotating rod one 18 drives the clamping block one 15 fixed at the center to rotate. At the same time, the rotating rod two 21 drives the clamping blocks two 17 fixed at both ends to rotate, so that the two end clamping blocks two 17 are separated from the corresponding clamping grooves two 22 on both sides. At the same time, the rotating clamping block one 15 is separated from the lower clamping groove one 16, and then the angle of the two side inclined supports 6 can be adjusted, so as to achieve the purpose of adjusting the up and down height of the inner end sliding seat 5;

[0031] When the angle of the inclined support 6 is larger, the heights of the two side sliding seats 5 become higher, and at the same time, the gap between the upper and lower rolls becomes larger. When the angle of the inclined support 6 is smaller, the heights of the two side sliding seats 5 become lower, and the gap between the upper and lower rolls becomes smaller. At the same time, as the height and angle of the upper end of the inclined support 6 are adjusted, the acute angle between the side support strips 14 on the inner side of the two side inclined supports 6 and the inclined support 6 also becomes larger or smaller. After determining the gap distance between the upper and lower rolls, loosen the two side rotating rods one 18 and the rotating rod two 21. The rotating rods are acted by the elastic force of the torsion springs at the joints. The clamping block one 15 and the two end clamping blocks two 17 are clamped into the corresponding groove positions. At this time, the angle of the inclined support 6 cannot be adjusted upward or downward, so as to achieve the purpose of fixing the up and down positions of the two side sliding seats 5;

[0032] As the gap between the upper and lower rolls changes, the pressure of the driven roll 3 located between the two side sliding seats 5 on the lower side driving roll 2 will increase or decrease accordingly. In order to make the driven roll 3 continuously and stably apply a good pressure on the lower side driving roll 2 after adjustment, the compression degree of the springs 10 in the two side sliding seats 5 is adjusted, so as to adjust the pressure on the lower side driving roll 2;

[0033] The rotation adjustment of the screw rod 9 is realized through the adjusting sleeve 12 connected to the upper end of the screw rod 9. As the screw rod 9 rotates, the extrusion block 11 threadedly connected thereto slides up and down between the two slide rods 8. When the extrusion block 11 slides downwards, the lower spring 10 is compressed shorter, and the pressure on the lower bearing seat 7 is tighter, that is, the pressure of the driven roller 3 on the lower driving roller 2 is stronger. This adjustment is applicable to the adjustment behavior after the driven roller 3 is adjusted upwards. When the gap between the upper and lower rollers becomes smaller, the progress of the spring 10 is appropriately adjusted, and the height of the two extrusion blocks 11 is adjusted upwards;

[0034] After the up and down adjustment of the extrusion block 11 is realized through the adjusting sleeve 12, the adjusting sleeve 12 is turned flat into the corresponding card slot on the sliding seat 5, and then the inserting rod 13 is passed through the inclined support 6 and the corresponding through hole on the sliding seat 5. The nut on one end of the inserting rod 13 is tightened, and the nut is made to closely adhere to the outer side surface of the sliding seat 5, so that the inclined support 6 is fixedly connected to the sliding seat 5.

[0035] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
