Description

TECHNICAL FIELD

[0001] The utility model relates to a waste edge winding device of slitting machine belongs to slitting machine waste edge winding technical field. BACKGROUND

[0002] In the process of slitting machine slitting material, the waste edge needs to be wound. The waste edge winding process is the same as the material slitting process, and tension needs to be established on the material. The floating roller mechanism commonly used in the slitting machine establishes tension on the material and keeps the tension stable. The floating roller mechanism used in the waste edge winding process in the current slitting machine is generally the same as the floating roller mechanism used in the material slitting process; but compared with the material width of the parent roll (the material width of the parent roll is large), the waste edge width is very small, which makes it difficult to adapt to the tension fluctuation of the floating roller mechanism in the waste edge winding process, and the waste edge is prone to breakage, affecting the normal winding of the waste edge. SUMMARY

[0010] The waste edge generated in the working process of the slitting machine successively passes through the front swing roller, the first guide roller, the second guide roller and the rear swing roller, and is then wound on the waste edge winding drum; in this process, the waste edge tension is applied to the air cylinder through the swing arm, and when the tightness of the waste edge changes, the piston rod of the air cylinder maintaining constant air pressure will extend or retract. Since the front swing roller and the rear swing roller are distributed on both sides of the pivot shaft of the swing arm, and the waste edge successively passes through the front swing roller, the first guide roller, the second guide roller and the rear swing roller, this makes the waste edge winding swing roller device of the present scheme form a labor-saving design similar to a labor-saving pulley mechanism, and the waste edge tension applied to the air cylinder through the swing arm will be amplified, so when the waste edge tension produces a small fluctuation, a response can be generated on the air cylinder, so that the piston rod of the air cylinder maintaining constant air pressure extends or retracts. When the piston rod of the air cylinder extends or retracts, it can be fed back to the controller to control the rotating speed of the waste edge winding drum winding the waste edge, so that the air cylinder returns to the initial equilibrium position.

In this way, the angle of the waste edge input into the front swing roller can be controlled by the material inlet guide roller to determine the angle of the waste edge input into the front swing roller, so as to ensure that the working state of the waste edge winding swing roller device is not affected by the output direction of the waste edge generated by the previous process.

[0034] In a specific embodiment, as shown in Figure 1 、 Figure 2 a waste edge winding swing roller device of a slitting machine, comprising a frame 1, a swing roller assembly 2, a first guide roller 3 and a second guide roller 4.

[0035] The swing roller assembly 2 comprises a cylinder 2.2, a swing arm 2.1, and two front and rear swing rollers rotatably arranged on the swing arm 2.1.

[0036] The swing arm 2.1 is rotatably arranged on the frame 1 through a rotating shaft 2.5. The front swing roller 2.3 and the rear swing roller 2.4 are distributed on both sides of the rotating shaft 2.5. The cylinder 2.2 drives the swing arm 2.1 to swing. One end of the cylinder 2.2 is hinged to the frame 1, and the other end of the cylinder 2.2 is hinged to the swing arm 2.1. The cylinder 2.2 is connected to an external input air pressure, and the air pressure of the cylinder 2.2 is kept constant.

[0037] The first guide roller 3 is rotatably arranged on the frame 1. The second guide roller 4 is rotatably arranged on the frame 1. The first guide roller 3 and the second guide roller 4 are located on both sides of the swing arm 2.1.

[0038] The waste edge of the slitting machine passes through the front swing roller 2.3, the first guide roller 3, the second guide roller 4 and the rear swing roller 2.4 in sequence.

[0039] The specific use of the waste edge winding swing roller device of the slitting machine in this embodiment is as follows,

[0040] The waste edge generated in the working process of the slitting machine is wound around the front swing roller 2.3, the first guide roller 3, the second guide roller 4 and the rear swing roller 2.4 in turn, and then is wound on the waste edge winding drum. In this process, the waste edge tension acts on the air cylinder 2.2 through the swing arm 2.1, and when the tightness of the waste edge changes, the piston rod of the air cylinder 2.2 maintaining constant air pressure will extend or retract. Since the front swing roller 2.3 and the rear swing roller 2.4 are distributed on both sides of the pivot shaft 2.5 of the swing arm 2.1, and the waste edge is wound around the front swing roller 2.3, the first guide roller 3, the second guide roller 4 and the rear swing roller 2.4 in turn, this makes the waste edge winding swing roller device of the scheme form a labor-saving design similar to a labor-saving pulley mechanism, and the waste edge tension acting on the air cylinder 2.2 through the swing arm 2.1 will be amplified, so that when the waste edge tension produces a small fluctuation, a response can be generated on the air cylinder 2.2, so that the piston rod of the air cylinder 2.2 maintaining constant air pressure extends or retracts. When the piston rod of the air cylinder 2.2 extends or retracts, it can be fed back to the controller to control the rotating speed of the waste edge winding drum winding the waste edge, so that the air cylinder 2.2 returns to the initial balance position. Thus, the waste edge winding swing roller device of the embodiment can effectively reduce the waste edge tension fluctuation and improve the waste edge tension stability, thereby effectively avoiding the problem of waste edge breakage.

[0041] Specific embodiment two, as shown in Figure 1 、 Figure 2 A waste edge winding swing roller device of a slitting machine, including a rack 1, a swing roller assembly 2, a first guide roller 3 and a second guide roller 4.

[0042] The swing roller assembly 2 includes an air cylinder 2.2, a swing arm 2.1 and front and rear swing rollers rotatably arranged on the swing arm 2.1.

[0043] The swing arm 2.1 is rotatably arranged on the rack 1 through a pivot shaft 2.5. The pivot shaft 2.5 is horizontally distributed. The front swing roller 2.3 and the rear swing roller 2.4 are distributed on both sides of the pivot shaft 2.5. The rotation axes of the front swing roller 2.3 and the rear swing roller 2.4 are parallel to the pivot shaft 2.5. The air cylinder 2.2 drives the swing arm 2.1 to swing. One end of the air cylinder 2.2 is hinged to the rack 1, and the other end of the air cylinder 2.2 is hinged to the swing arm 2.1. A sensor for detecting the moving stroke of the piston rod of the air cylinder 2.2 is arranged on the air cylinder 2.2. The air cylinder 2.2 is connected to an external input air pressure, and the air pressure of the air cylinder 2.2 is kept constant.

[0044] In the embodiment, the front swing roller 2.3 and the rear swing roller 2.4 are symmetrically distributed on both sides of the rotating shaft 2.5. The gravity centers of the components in the swing roller assembly 2 except the air cylinder are located on or close to the rotating shaft. The front swing roller 2.3 and the rear swing roller 2.4 are distributed at the two ends of the swing arm 2.1. In this way, the weight of the front swing roller 2.3 and the rear swing roller 2.4 acting on the swing arm 2.1 will be counteracted, so that the swing roller assembly 2 is in a static balance state, and the air cylinder 2.2 does not need to overcome the weight of the front swing roller 2.3 and the rear swing roller 2.4. In this way, the sensitivity of the air cylinder 2.2 in response can be improved, so as to further reduce the waste edge tension fluctuation and improve the waste edge tension stability.

[0045] It should be noted that the front swing roller 2.3 and the rear swing roller 2.4 are symmetrically distributed on both sides of the rotating shaft 2.5 so that the gravity centers of the components in the swing roller assembly 2 except the air cylinder are located on or close to the rotating shaft. This is only a preferred solution in the embodiment. In actual production, the front swing roller 2.3 and the rear swing roller 2.4 can also be asymmetrically distributed, and the distance between the front swing roller 2.3 and the rotating shaft 2.5 and the distance between the rear swing roller 2.4 and the rotating shaft 2.5 can be set to different distances according to needs.

[0046] The first guide roller 3 is rotatably arranged on the rack 1. The rotating shaft of the first guide roller 3 is parallel to the rotating shaft 2.5. The second guide roller 4 is rotatably arranged on the rack 1. The rotating shaft of the second guide roller 4 is parallel to the rotating shaft 2.5. The first guide roller 3 and the second guide roller 4 are located on both sides of the swing arm 2.1.

[0047] The waste edge 8 of the slitting machine passes through the front swing roller 2.3, the first guide roller 3, the second guide roller 4 and the rear swing roller 2.4 in sequence.

[0048] The specific use of the waste edge winding swing roller device of the slitting machine in the embodiment is as follows,

[0049] The waste edge 8 generated in the working process of the slitting machine passes through the front swing roller 2.3, the first guide roller 3, the second guide roller 4 and the rear swing roller 2.4 in sequence, and is then wound on the waste edge winding drum. In this process, the waste edge tension acts on the air cylinder 2.2 through the swing arm 2.1, and when the tightness of the waste edge changes, the piston rod of the air cylinder 2.2 maintaining constant air pressure will extend or retract. Since the front swing roller 2.3 and the rear swing roller 2.4 are distributed on both sides of the pivot shaft 2.5 of the swing arm 2.1, and the waste edge passes through the front swing roller 2.3, the first guide roller 3, the second guide roller 4 and the rear swing roller 2.4 in sequence, this makes the waste edge winding swing roller device of the present scheme form a labor-saving design similar to a labor-saving pulley mechanism, and the waste edge tension acting on the air cylinder 2.2 through the swing arm 2.1 will be amplified, so that when the waste edge tension produces a small fluctuation, a response can be generated on the air cylinder 2.2, so that the piston rod of the air cylinder 2.2 maintaining constant air pressure extends or retracts. When the piston rod of the air cylinder 2.2 extends or retracts, it can be sensed by a sensor and fed back to a controller to control the rotating speed of the waste edge winding drum 10 winding the waste edge, so that the air cylinder 2.2 returns to the initial equilibrium position. Thus, the waste edge winding swing roller device of the embodiment can effectively reduce the waste edge tension fluctuation and improve the waste edge tension stability, thereby effectively avoiding the problem of waste edge breakage.

[0050] Further, a waste edge winding swing roller device of a slitting machine further comprises an inlet guide roller 5 arranged on the rack 1, the inlet guide roller 5 and the first guide roller 3 are located on the same side of the swing arm 2.1, and the inlet guide roller 5 is parallel to the first guide roller 3. The waste edge of the slitting machine passes through the inlet guide roller 5, the front swing roller 2.3, the first guide roller 3, the second guide roller 4 and the rear swing roller 2.4 in sequence. In this way, the angle of the waste edge input into the front swing roller 2.3 can be controlled by the inlet guide roller 5 to determine the angle of the waste edge input into the front swing roller 2.3, so as to ensure that the working state of the waste edge winding swing roller device is not affected by the output direction of the waste edge generated by the previous process.

[0051] A waste edge winding swing roller device of a slitting machine further comprises an outlet guide roller 6 arranged on the rack 1. The outlet guide roller 6 and the second guide roller 4 are located on the same side of the swing arm 2.1. The outlet guide roller 6 is parallel to the second guide roller 4. The waste edge of the slitting machine passes through the inlet guide roller 5, the front swing roller 2.3, the first guide roller 3, the second guide roller 4, the rear swing roller 2.4 and the outlet guide roller 6 in sequence. In this way, the angle of the waste edge output by the rear swing roller 2.4 can be controlled by the outlet guide roller 6 to determine the angle of the waste edge output by the rear swing roller 2.4, so as to make the working state of the waste edge winding swing roller device not affected by the installation position of the waste edge winding drum.

[0052] Further, two scrap edge guide wheels 9 are arranged on the frame 1. The scrap edge guide wheels 9 are rotatably arranged on the frame 1. The scrap edge guide wheels 9 form a scrap edge guide inlet 9.1 between the two scrap edge guide wheels 9. The scrap edge of the slitting machine first passes through the scrap edge guide inlet 9.1 and then bypasses the front swing roller 2.3. Specifically, the scrap edge of the slitting machine first passes through the scrap edge guide inlet 9.1 and then bypasses the material inlet guide roller 5, the front swing roller 2.3, the first guide roller 3, the second guide roller 4, the rear swing roller 2.4 and the material outlet guide roller 6 in sequence. In this way, the scrap edge generated in the previous process can be guided through the scrap edge guide inlet 9.1 and then bypass the material inlet guide roller 5, so as to ensure that the position of the scrap edge passing through the scrap edge winding swing roller device is within a relatively fixed range.

[0053] Further, two limiting members 7 are arranged on the frame 1, and the swing arm 2.1 is located between the two limiting members 7. The two limiting members 7 limit the swing angle of the swing arm 2.1. The limiting member 7 is a limiting block or a limiting rod or a rotatably arranged limiting wheel.

[0055] The first guide roller 3 is located above the swing arm 2.1. The material inlet guide roller 5 is also located above the swing arm 2.1. In this embodiment, the material inlet guide roller 5 and the first guide roller 3 are arranged at the same height, which facilitates the arrangement of the material inlet guide roller 5 and the first guide roller 3. Of course, arranging the material inlet guide roller 5 and the first guide roller 3 at the same height is only a preferred scheme of this embodiment, and in the actual manufacturing process, the material inlet guide roller 5 and the first guide roller 3 can also not be arranged at the same height.

[0056] The second guide roller 4 is located below the swing arm 2.1. The material outlet guide roller 6 is also located above the swing arm 2.1.
