Description

Technical Field

[0001] This utility model relates to the field of slitting machine equipment technology, and in particular to a roller device for a slitting machine. Background Technology

[0002] A slitting machine is a mechanical device that cuts wide sheets of paper, mica tape, or film into multiple narrow strips of material. It is commonly used in industries such as packaging, printing, electronic materials, and textiles. Existing aluminum foil, after being printed and coated, needs to be slitted on a slitting machine to cut large rolls of semi-finished aluminum foil into the required specifications and sizes. The aluminum foil is first unwound and then rewound on the slitting machine.

[0003] During the winding process of existing slitting machines, the thickness and weight of aluminum foil continuously increase as it is wound around the winding shaft. In this process, the winding shaft is at risk of being bent, which means that the aluminum foil cannot be tightly wound onto the winding shaft during subsequent winding, resulting in wrinkles in the roll material and affecting subsequent transportation and use. Summary of the Invention

[0004] To address the issue that during the winding process of existing slitting machines, the thickness and weight of the strip continuously increase as it winds onto the winding shaft, posing a risk of the winding shaft bending, this invention proposes a roller device for slitting machines. By using rollers positioned on the underside of the winding shaft, the strip roll on the winding shaft is supported, ensuring that the winding shaft is not bent and that the strip roll is tightly wound onto the winding shaft.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A roller device for a slitting machine is disposed below the take-up shaft of the slitting machine. The take-up shaft is rotatably mounted on the frame and has a strip wound on it. The roller device includes a telescopic assembly, a fixed block, a support seat, a mounting seat, and a roller rotatably disposed between the two mounting seats. The fixed block is fixed to the upwardly extending output end of the telescopic assembly. The mounting seat is slidably disposed on the support seat and fixedly connected to the fixed block. The upper side of the roller contacts the lower side of the strip roll. The diameter of the strip roll on the take-up shaft gradually increases over time. Therefore, the mounting seat, which is fixed to the fixed block at the upper end of the telescopic assembly, carries the roller up to contact the lower side of the strip roll and then slowly descends.

[0006] Preferably, the telescopic component is a hydraulic cylinder, a pneumatic cylinder, or an electric actuator.

[0007] Preferably, each of the two support seats has a slide rail fixed on one side opposite to the support seat, and the mounting seat has a slider that cooperates with the slide rail fixed on the side near the support seat.

[0008] Preferably, each of the mounting seats on both sides is provided with a bearing seat, and the idler roller is rotatably mounted on the bearing seat through a bearing inside the bearing seat.

[0009] Preferably, the mounting base has a mounting groove, the bearing seat is slidably disposed in the mounting groove, there is a gap between the upper top surface of the bearing seat and the upper top surface of the mounting base, a mounting plate is fixed on the upper top surface of the mounting base, the mounting plate is located on the upper side of the mounting groove, the upper end of the bearing seat has an inverted "T" shaped groove, a limiting plate is placed in the groove, a screw is threadedly connected to the mounting plate, the lower end of the screw passes through the limiting plate and extends into the groove, and is fixedly connected to the limiting plate.

[0010] Preferably, a limiting groove is formed on the side of the bearing housing, and a vertical limiting rod is fixed in the mounting groove, the limiting rod matching the limiting groove. Limiting grooves are formed on both sides of the bearing housing.

[0011] Preferably, a connecting rod is fixed between the mounting seats on both sides. This ensures the synchronous up-and-down movement of the mounting seats, thereby ensuring the horizontality of both sides of the idler roller.

[0012] The beneficial effects of this utility model through the above technical solution are as follows: the fixed block fixed on the output end of the telescopic component in this utility model is fixedly connected to the mounting seat slidably set on the support seat, and the two ends of the idler roller are rotatably set on the mounting seats on both sides. The slow contraction of the telescopic rod of the telescopic component enables the idler roller to support the belt roll with the continuously increasing roll diameter, ensuring that the winding shaft will not be bent, making the winding of the belt roll on the winding shaft more stable, avoiding wrinkles in the belt roll, and improving the winding quality.

[0014] In the attached diagram, the following numbers are used: 1 is the telescopic component, 2 is the fixing block, 3 is the support base, 4 is the mounting base, 5 is the idler roller, 6 is the slide rail, 7 is the slider, 8 is the bearing seat, 9 is the mounting groove, 10 is the winding tension shaft, 11 is the mounting plate, 12 is the limiting plate, 13 is the screw, 14 is the limiting groove, 15 is the connecting rod, 20 is the frame, and 30 is the roll. Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1-4 As shown, this embodiment provides a roller device for a slitting machine, which is set on the lower side of the winding shaft 10 of the slitting machine. The winding shaft 10 is rotatably mounted on the frame 20. A strip roll 30 (aluminum foil roll) is wound on the winding shaft 20. A power device (not shown in the figure) is set on the frame 20. The power device can be a motor. The power device drives the winding shaft 10 to rotate, so as to realize the winding of the aluminum foil roll on the winding shaft 10.

[0016] The idler roller device is mainly used to support aluminum foil rolls with continuously increasing diameters, preventing excessive weight of the aluminum foil roll during winding, which could cause the winding tension shaft 10 to bend, resulting in wrinkles in the aluminum foil roll and reducing winding quality; Reference Figure 1 and Figure 2 The idler roller device includes a telescopic assembly 1, a fixed block 2, a support seat 3, a mounting seat 4, and an idler roller 5 rotatably disposed between the two mounting seats 4; In this embodiment, the idler roller device is located between two frames 20 and below the roll 30 (aluminum foil roll). In this embodiment, the frame 20 is fixed on the workshop floor. In order to increase the stroke of the telescopic component 1, an installation groove with a certain depth is opened on the workshop floor, and the bottom end of the telescopic component 1 is fixed in the installation groove. The telescopic component 1 can be a hydraulic cylinder, a pneumatic cylinder or an electric actuator.

[0017] In this embodiment, the idler roller 5 has a diameter of 180mm and a length of 1860mm. The idler roller 5 is made of polyurethane material to ensure that the idler roller 5 has a certain degree of elasticity and to avoid vibration when the strip roll 30 drives the idler roller 5 to rotate. Vibration of the strip roll 30 will cause the strip roll 30 to be slightly loose, which will easily lead to quality problems. The hardness of the idler roller 5 is 65-70HSD, and the idler roller 5 is high in the middle and low at both ends, with a certain convexity ranging from 0.06mm to 0.07mm. When taking up a single strip roll 30, the weight in the middle is greater. The convex middle part of the idler roller 5 can distribute the weight of the strip roll 30 to both sides, thereby improving the winding quality.

[0018] The fixing block 2 is fixed to the upward-extending output end of the telescopic assembly 1 by a pin. The mounting base 4 is slidably mounted on the support base 3. Specifically, each of the two sides of the support base 3 has a slide rail 6 fixed to its opposite side by bolts. The mounting base 4 has a slider 7 that cooperates with the slide rail 6 fixed to its side near the support base 3. The slider 7 is welded to the mounting base 4. The fixing block 2 is welded to the mounting base 4. The upper side of the idler roller 5 contacts the lower side of the roll 30. As the diameter of the roll 30 increases and the gravity increases, the telescopic assembly 1 (hydraulic cylinder) retracts downward accordingly.

[0019] refer to Figure 2 and Figure 3 Each of the two mounting seats 4 is provided with a bearing seat 8. The roller 5 is rotatably mounted on the bearing seat 8 through a bearing (not shown in the figure) inside the bearing seat 8. The mounting seat 4 is provided with a mounting groove 9. The bearing seat 8 is slidably mounted in the mounting groove 9. Specifically, two opposing limiting grooves 14 are provided on the two sides of the bearing seat 8. A vertical limiting rod is welded and fixed on the inner wall of the mounting groove 9. The limiting rod matches the limiting groove 14 to realize the up and down sliding of the bearing seat 8 on the mounting groove 9.

[0020] Furthermore, there is a gap between the upper top surface of the bearing seat 8 and the upper top surface of the mounting base 4. A mounting plate 11 is bolted to the upper top surface of the mounting base 4. The mounting plate 11 is located above the mounting groove 9. An inverted "T"-shaped groove is formed at the upper end of the bearing seat 8. A limiting plate 12 is placed within the groove. A screw 13 is threaded onto the mounting plate 11. The lower end of the screw 13 passes through the limiting plate 12, extends into the groove, and is fixedly connected to the limiting plate 12. The rotation of the screw 13 adjusts the vertical position of the bearing seat 8 within the mounting groove 9. This is to adjust the vertical position of the idler roller 5, thereby adjusting the vertical travel limits of the idler roller 5 to adapt to different belt coils 30.

[0021] In other embodiments, reference is made to... Figure 4 A connecting rod 14 is fixed between the mounting seats 4 on both sides. The connecting rod 14 ensures the synchronous up and down movement of the mounting seats 4, thereby ensuring the horizontal level of the idler roller 5.

[0022] When using this device, first adjust the upper and lower positions of the bearing seat 8 in the mounting groove 9 by turning the screw 13. Then, activate the telescopic assembly 1. The fixing block 2 on the telescopic assembly 1 drives the mounting seat 4 to slide on the support seat 3 until the upper side of the idler roller 5 contacts the lower side of the roll 30. Then, the slitting machine works. As the diameter of the roll 30 wound on the take-up shaft 10 increases and the weight increases, the telescopic assembly 1 (hydraulic cylinder) retracts downward accordingly, so that the idler roller 5 can always support the roll 30, ensuring that the take-up shaft 10 will not be bent. This makes the winding of the roll 30 on the take-up shaft 10 more stable, avoids wrinkles in the roll 30, and improves the winding quality.

[0023] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
