Description

Technical Field

[0001] This utility model relates to a die-cutting and separating device for a die-cutting machine. Background Technology

[0002] Die-cutting machines are used for die-cutting continuous roll materials (such as paper or film rolls). A die-cutting machine includes an unwinding device, a tensioning device, a web guiding device, a die-cutting mechanism, a separating mechanism, a finished product collection mechanism, and a waste rewinding mechanism. After the continuous roll material is die-cut in the die-cutting mechanism, the separating mechanism is needed to separate the finished product units from the waste. Generally, after die-cutting, the continuous roll material forms rows of side-by-side finished product units. These units are separated by corresponding waste material (i.e., waste edges) between them and between them front and back. After removing each finished product unit, the continuous roll material leaves behind holes (at this point, the continuous roll material is waste). The die-cutting mechanism includes a bottom die and an upper die (e.g., the bottom die is fixed, and the upper die moves up and down to cooperate with the die-cutting) to die-cut finished product units from the continuous roll material. The front and back dimensions of the finished product units (i.e., the dimensions along the direction of the continuous roll material's movement) vary depending on production requirements. Furthermore, after being output from the die-cutting mechanism, the die-cut finished product units may detach from the continuous roll material, affecting subsequent normal separation and collection.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the implementation of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0028] Referring to the accompanying drawings, in this embodiment, the die-cutting and separating device of the die-cutting machine includes a die-cutting mechanism 2 and a separating mechanism 4. The die-cutting mechanism 2 and the separating mechanism 4 are mounted on the frame 1. The die-cutting mechanism 2 is used for die-cutting continuous roll material, and the separating mechanism 4 is used to separate the finished product units formed by die-cutting on the continuous roll material from the waste material.

[0029] The frame 1 is equipped with a longitudinal adjustment bracket 5, and the die-cutting mechanism 2 is mounted on the longitudinal adjustment bracket 5. The longitudinal adjustment bracket 5 is connected to a front and rear longitudinal adjustment device 50. The front and rear longitudinal adjustment device 50 works together to drive the longitudinal adjustment bracket 5 to move back and forth longitudinally on the frame 1. The die-cutting mechanism 2 mounted on the longitudinal adjustment bracket 5 can move back and forth longitudinally along with it so as to adjust the (front and rear) position as needed to meet the adjustment requirements of the front and rear specification size changes of the finished product unit.

[0030] The separation mechanism 4 includes a conveyor belt device 6, which includes a feeding conveyor belt 60, an input shaft 61, and an output shaft 62. The feeding conveyor belt 60 is driven and wound around the output shaft 62 and the input shaft 61. That is, the input end of the feeding conveyor belt 60 is located at the input shaft 61, and the output end of the feeding conveyor belt 60 is located at the output shaft 62. The feeding conveyor belt 60 is driven and supported by the output shaft 62 and the input shaft 61.

[0031] The input shaft 61 is mounted on the longitudinal adjustment bracket 5, which supports the rotation of the input shaft 61. When the die-cutting mechanism 2 moves back and forth longitudinally with the longitudinal adjustment bracket 5, the input shaft 61 also moves back and forth longitudinally with the longitudinal adjustment bracket 5. The position of the input end of the feeding conveyor belt 60 wrapped around the input shaft 61 will also move back and forth. The input shaft 61 is located in front of the die-cutting mechanism 2. The discharge end of the die-cutting mechanism 2 is connected to the input end of the feeding conveyor belt 60 in front. During the longitudinal adjustment of the longitudinal adjustment bracket 5, the feeding conveyor belt 60 and the die-cutting mechanism 2 remain connected, and the material conveying is not affected.

[0032] The output shaft 62 is mounted on the frame 1 and is supported by the frame 1 to rotate. The output shaft 62 is located in front of the input shaft 61. The die-cut roll material on the feeding conveyor belt 60 is output from the input end to the output end.

[0033] In the die-cutting and separating device of this die-cutting machine, the die-cutting mechanism 2 and the separating mechanism 4 are connected by a feeding conveyor belt 60. The feeding conveyor belt 60 supports the die-cut continuous roll material for conveying, so that the finished units on the die-cut continuous roll material will not accidentally detach or fall off before separation. The input end of the feeding conveyor belt 60 is wound around the input end rotating shaft 61. The input end rotating shaft 61 and the die-cutting mechanism 2 are installed on the longitudinal adjustment bracket 5. The input end rotating shaft 61 and the die-cutting mechanism 2 can move back and forth longitudinally on the frame 1 together with the longitudinal adjustment bracket 5 to adjust their positions to meet the adjustment requirements of changes in the front and rear specifications of the finished units. During the longitudinal adjustment of the longitudinal adjustment bracket 5, the feeding conveyor belt 60 and the die-cutting mechanism 2 always remain connected, and the material conveying is not affected.

[0034] The following optimizations or further explanations can be made based on the above embodiments.

[0035] For example, the output shaft 62 or the input shaft 61 is connected to the feeding drive device 63, which drives the output shaft 62 or the input shaft 61 to rotate, thereby driving the feeding conveyor belt 60 to run. For example, the feeding drive device 63 includes a feeding drive motor (such as a servo motor); the feeding drive motor can be mounted on the frame 1 or the longitudinal adjustment bracket 5. In the figure, it is mounted on the frame 1. The longitudinal adjustment bracket 5 has a relatively low load, and the feeding drive motor is supported by the frame 1, resulting in relatively high stability.

[0036] For example, the discharge end of the die-cutting mechanism 2 is also connected to a transition connecting plate 7. The transition connecting plate 7 is connected and configured at the input end of the feeding conveyor belt 60. The transition connecting plate 7 can fill the gap between the discharge end of the die-cutting mechanism 2 and the input end of the feeding conveyor belt 60, so as to avoid affecting the conveying of the continuous roll material.

[0037] Further optimization involves the feeding conveyor belt 60 being equipped with an adjusting shaft 64. The feeding conveyor belt 60 is wound around the adjusting shaft 64, which is used to coordinate with the input shaft 61 of the conveyor belt device 6 to adjust its position by moving longitudinally back and forth with the longitudinal adjustment bracket 5. Both ends of the adjusting shaft 64 are respectively mounted on a movable adjusting seat 65, which is connected to a movable adjustment device 9. The movable adjustment device 9 can drive the movable adjusting seat 65 (and its adjusting shaft 64) to adjust its position. After the input shaft 61 has moved longitudinally back and forth with the longitudinal adjustment bracket 5, the movable adjustment device 9 can be controlled to adjust the corresponding position of the adjusting shaft 64, ensuring that the feeding conveyor belt 60 remains taut and maintains normal operation even after the position of the input shaft 61 at the input end of the feeding conveyor belt 60 has been adjusted. The output shaft 62 operates on the frame 1. Compared to the input shaft 61, which adjusts back and forth with the longitudinal adjustment bracket 5, the output shaft 62's relative position is fixed on the frame 1.

[0038] For example, the movable adjustment seat 65 adopts a linear reciprocating movable adjustment seat. The movable adjustment seat 65 is equipped with a linear guide rail 90. The movable adjustment seat 65 (and its adjustment shaft 64) moves linearly along the linear guide rail 90 to adjust its position. The structure is relatively simple and the operation is stable. There are many ways to drive the movable adjustment device 9 to move linearly on the linear guide rail 90 to adjust its position, and these methods are relatively mature. For example, the movable adjustment device 9 includes an adjusting screw 91 and an adjusting nut. The adjusting screw 91 and the adjusting nut are connected for transmission. The adjusting screw 91 is set on the screw seat of the frame 1, and the adjusting nut is set on the movable adjustment seat 65.

[0039] For example, the linear guide 90 is set as a vertical guide, the axis of the adjusting screw 91 is set vertically, and the movable adjusting seat 65 is set as a lifting seat. The movable adjusting seat 65 is configured on the vertical guide for lifting and moving to adjust the corresponding position. A vertical slide groove can be opened on the wall panel of the frame 1 as the linear guide 90 to reduce costs. The movable adjusting seat 65 or the adjusting shaft 64 is connected to the linear guide 90. For example, the adjusting shaft 64 includes a supporting spindle 66 and a roller. A bearing is provided between the roller and the supporting spindle 66. The supporting spindle 66 cooperates to support the roller to rotate. The two ends of the supporting spindle 66 are fixedly connected to the movable adjusting seat 65. The supporting spindle 66 passes through the vertical slide groove, and the vertical slide groove guides the supporting spindle 66 to lift and slide (an additional sliding sleeve (such as a copper sleeve) can be added to make the lifting and sliding in the vertical slide groove smoother and longer).

[0040] Further optimization involves setting corresponding adjusting screws 91 on the left and right sides of the frame 1. The left and right adjusting screws 91 are respectively connected to the synchronous drive shaft 93 arranged laterally on the axis. The synchronous drive shaft 93 is mounted on the frame 1. A bevel gear transmission pair 94 is provided between the synchronous drive shaft 93 and the adjusting screw 91. The left adjusting screw 91 is connected to the synchronous drive shaft 93 by the bevel gear transmission pair 94, and the right adjusting screw 91 is connected to the synchronous drive shaft 93 by the bevel gear transmission pair 94. During the operation of the synchronous drive shaft 93, the left and right adjusting screws 91 are driven to run synchronously by the bevel gear transmission pair 94 (including the first bevel gear and the second bevel gear in a paired meshing manner). The left and right moving adjusting seats 65 can run synchronously, and the balance of the left and right ends of the adjusting shaft 64 is well guaranteed, and the feeding conveyor belt 60 feeds materials stably.

[0041] The longitudinal shifting and adjusting device 50 includes a longitudinal guide rail 51, and a longitudinal shifting adjusting bracket 5 is disposed on the longitudinal guide rail 51. The longitudinal guide rail 51, in conjunction with the longitudinal shifting adjusting bracket 5, stabilizes the longitudinal movement and adjusts the position. The area between the output end rotating shaft 62 and the input end rotating shaft 61 is the feeding area of ​​the feeding conveyor belt 60, that is, the feeding area between the input and output ends of the feeding conveyor belt 60. The adjusting rotating shaft 64 is located below the feeding area, and is positioned below the output end rotating shaft 62 and the input end rotating shaft 61. In addition, Guide rollers 68 are provided between the adjusting shaft 64 and the output shaft 62, and between the adjusting shaft 64 and the input shaft 61. The guide rollers 68 are mounted on the frame 1 and connected to the outer side of the feeding conveyor belt 60. During the adjustment of the position of the adjusting shaft 64 with the movable adjusting seat 65, the guide rollers 68 on the front and rear sides of the adjusting shaft 64 guide the feeding conveyor belt 60, ensuring stable contact between the adjusting shaft 64 and the feeding conveyor belt 60. The longitudinal shifting device 50 can drive the longitudinal shifting bracket 5 to move longitudinally back and forth on the longitudinal guide rail 51 on the frame 1 in various ways, including belt drive structure, gear and rack drive structure, or screw and nut drive structure 52 (which can be equipped with a side handwheel 53 for operation via bevel gear pairs, etc.).
