Description

Technical Field

[0001] The utility model relates to the technical field of composite machinery, in particular to a damping swing roller device for adjusting unwinding tension. Background Art

[0002] Thermal plate paper (or thermal paper) is a special consumable for digital integrated quick printing machines. It is composed of at least two materials and requires composite equipment for production. The unwinding part of the existing composite equipment includes an unwinding frame, a tension roller and several guide rollers.

[0003] Since the guide rollers are fixed, when the coil on the unwinding rack is not round, there will be large fluctuations in the unwinding tension, which will affect the composite quality. For example, in order to improve production efficiency and reduce unnecessary scrapping, a double-station unwinding rack will use two stations to automatically switch for continuous production. During the switching process of the two stations, large fluctuations in the unwinding tension are likely to occur, causing the two materials being compounded to be rolled into the glue coating roller of the composite equipment, resulting in downtime and material scrapping.

[0019] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0020] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0021] Reference Figure 1As shown, this embodiment provides a damping swing roller device for adjusting unwinding tension (hereinafter referred to as the damping swing roller device), the damping swing roller device includes a guide roller unit 8 and an unwinding unit 7 for placing a coil, the damping swing roller device also includes a swing roller assembly 9, the swing roller assembly 9 is arranged between the unwinding unit 7 and the guide roller unit 8, the swing roller assembly 9 includes a swingable swing roller unit and an eccentric unit for adjusting the swing angle of the swing roller unit, and the swing roller unit is suspended, the coil on the unwinding unit 7 is sequentially wound around the swing roller unit and the guide roller unit 8, the eccentric unit drives the swing roller unit to swing, so as to adjust the force applied by the swing roller unit to the coil, thereby forming a damping setting for the unwinding tension.

[0022] In this embodiment, the unwinding unit 7 includes two unwinding rollers for placing the coiled material, and the guide roller unit 8 includes one guide roller.

[0023] The specific coiled material is the coiled paper or the thermal coating film required for the production of thermal paper, and the damping swing roller device is the unwinding part of the composite equipment used for the composite production of thermal paper.

[0024] When the unwinding tension in composite production suddenly fluctuates too much, the eccentric unit drives the swing roller unit to swing or rotate to a certain swing angle, so as to adaptively adjust the force applied by the swing roller unit to the coil, thereby suppressing the unwinding tension from continuing to increase or decrease, that is, adaptively buffering the fluctuation amplitude of the unwinding tension, thereby having a damping effect on the fluctuation of the unwinding tension, so as to reduce the adverse effects on the composite.

[0025] Of course, in other embodiments, the number of the unwinding rollers may be more than 3, and the number of the guide rollers may be more than 2.

[0026] In another preferred embodiment, the swing roller unit comprises a swing roller 1 and a rotatable swing arm 2, the swing roller 1 is assembled on the swing arm 2 to form a swingable arrangement, and the swing roller 1 is suspended.

[0027] The eccentric unit includes a matching screw rod 5 and an eccentric nut 6. The center of the screw rod 5 is fixed to the lower side of the swing arm 2 close to the swing roller 1 to achieve that the lengths of the screw rod 5 parts distributed on both sides of the swing arm 2 are the same, and the screw rod 5 is perpendicular to the swing arm 2. The eccentric nut 6 is rotatably sleeved on the screw rod 5, and the eccentric nut 6 is arranged on both sides of the screw rod 5.

[0028] In a specific implementation, the swing roller unit also includes a fixed support 4, which is fixed on the frame of the composite equipment. The number of swing arms 2 and screw rods 5 is 2 each, and the number of corresponding eccentric nuts 6 is 4. The upper ends of the two swing arms 2 facing away from the swing roller 1 are respectively hinged to the support 4 through a hinge shaft 3. Each swing arm 2 corresponds to a screw rod 5 and two eccentric nuts 6, so that the swing arm 2 can swing around the hinge shaft 3 or rotate within a certain angle range. The swing roller 1 and the swing arm 2 are both suspended to simplify the connection method and achieve high reliability of the damping swing roller device.

[0029] When the damping swing roller device needs to switch coils with different tension strengths, the corresponding gravity torque is formed by adjusting the positions of the four eccentric nuts 6 on the corresponding screw rods 5 to change the inclination angle or swing angle of the swing arm 2 to ensure that the buffering effect of the damping swing roller device is optimal.

[0030] Of course, in other embodiments, the screw rod 5 and the swing arm 2 may also be cross-arranged. A preferred embodiment is that the screw rod 5 is perpendicular to the swing arm 2, and any part of the screw rod 5 (such as one end of the screw rod 5) can be connected to the swing arm 2.

[0031] Furthermore, the eccentric nut 6 can also be arranged on one side of the screw rod 5, so that the swing angle of the swing arm 2 can also be adjusted.

[0032] Further preferably, when the swing angle of the swing roller unit is 0 degrees, that is, the swing arm 2 hangs vertically and is perpendicular to the horizontal plane, the traction angle A between the two ends of the coiled material passing through the swing roller 1 of the swing roller unit is 100 degrees, so as to ensure that the swing roller assembly 9 has sufficient swing range to adaptively buffer the fluctuation of the unwinding tension.

[0033] In this specific embodiment, the unwinding roller and the guide roller are arranged on the left and right, the swing roller 1 is located between the unwinding roller and the guide roller, and the composite operation direction of the coil is from left to right.

[0034] During lamination, if the unwinding tension suddenly increases, the unwinding tension overcomes the gravity moment of the eccentric unit and pulls the swing roller 1 and the swing arm 2 to swing to the right, thereby reducing the tension of the coil, that is, reducing the unwinding tension to the appropriate range required for lamination production.

[0035] If the unwinding tension suddenly decreases, the gravity moment of the eccentric unit drives the swing roller 1 together with the pendulum to swing back to the left, thereby increasing the tension of the coil, that is, increasing the unwinding tension to a suitable range required for composite production.

[0036] In this way, the damping swing roller device can adaptively buffer the fluctuation amplitude of the unwinding tension, that is, it can have a damping effect on the fluctuation change of the unwinding tension, so as to reduce the adverse effect of the fluctuation of the unwinding tension on the subsequent composite position, such as preventing the coil being composited from being wound into the glue coating roller of the composite equipment, thereby avoiding shutdown and material scrapping.

[0037] Of course, in other embodiments, the traction angle A between the two ends of the coiled material passing around the swing roller 1 may also be greater than 90 degrees, and the preferred traction angle A is 100 degrees.

[0038] In another preferred embodiment, a tension roller 10 for adjusting the unwinding tension is provided between the swing roller assembly 9 and the unwinding unit 7 to ensure that the coil has a certain tension or tightness during the lamination process.

[0039] Although the present invention has been specifically demonstrated and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes may be made to the present invention in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims, all of which are within the scope of protection of the present invention.
