Abstract
Description
Technical Field
[0001] The utility model relates to the field of printing, in particular to an open-chain drive tension control mechanism and an automatic die-cutting machine with the open-chain drive tension control mechanism. Background Art
[0002] A die-cutting machine is a device used in industrial production, mainly for die-cutting various materials (such as paper, plastic, rubber, metal foil, etc.) to achieve specific shapes and sizes. Die-cutting machines are widely used in industries such as packaging, printing, electronics, automotive, and clothing.
[0003] For a horizontal flat-bed automatic die-cutting machine and an automatic hot stamping and die-cutting machine with single-sheet paper feeding, after the printing paper is hot stamped and die-cut, it is collected and stacked on the delivery board or the finished product board. Driven by a motor, the delivery board or the finished product board moves up and down through four chains. One end of each of the four chains is fixed at the four corners of the delivery board or the finished product board, and the other end is in an open state. Generally, a weight is fixedly connected to the open end of chain 1-2 to ensure that the chain meshes with the sprocket without skipping teeth and moves smoothly when the delivery board or the finished product board moves up and down. As Figure 1 shown. There is also a design in which a steel wire rope 2-4 is fixedly connected to the open end of chain 2-3. The other end of the steel wire rope is fixedly connected to the delivery board or the finished product board after passing through a pulley 2-5 with a U-shaped groove, closing the drive chain again to ensure the tension of the chain during movement. As Figure 2 shown. During the working process, under the impact of the load and the moment of starting and stopping of the delivery board or the finished product board on the chain and the steel wire rope, the fatigue wear of the steel wire rope 2-4 through the U-shaped groove pulley 2-5 is relatively large, and it is easy to cause fatigue fracture of the steel wire rope, resulting in equipment failures. In the structure where a weight is fixedly connected to the open end of chain 1-2, during the working process, the weight is prone to generate impact noise with the protective housing, and it is also restricted by the vertical movement space of the weight, which needs to be improved. Summary of the Utility Model
[0004] A series of simplified concepts are introduced in the summary of the utility model. These simplified concepts are all simplified from the prior art in this field, and will be further described in detail in the specific implementation part. The summary of the utility model does not mean to attempt to define the key features and essential technical features of the claimed technical solution, nor does it mean to attempt to determine the protection scope of the claimed technical solution.
[0005] The technical problem to be solved by the utility model is to provide an open-chain drive tension control mechanism and an automatic die-cutting machine with the open-chain drive tension control mechanism.
[0006] To solve the above technical problems, the open-chain drive tension control mechanism provided by the present utility model includes:
[0007] The finished product receiving platen 4-23 is formed as a square flat platen for collecting and stacking finished products.
[0008] Four chains are respectively installed at the four corners of the finished product receiving platen 4-23, and the flat platen is driven to rise or fall by the motor II 4-17.
[0009] The sprocket support shaft II 4-14 is between the operating surface wall panel and the drive surface wall panel for supporting two driven sprockets II 4-15.
[0010] Two driven sprockets II 4-15 are respectively installed on both sides of the sprocket support shaft II 4-14 and can rotate.
[0011] The main drive shaft II 4-18 is supported and installed between the operating surface wall panel and the drive surface wall panel, and its output shaft is fixedly connected to the output shaft of the motor II 4-17 outside the drive side wall panel.
[0012] Two double-row sprockets II 4-19 are respectively fixedly installed on both sides of the main drive shaft II 4-18 and rotate with the shaft. One of the double-row sprockets II 4-19 is coplanar with the driven sprocket II 4-15.
[0013] Two finished product receiving platen chains I 4-16 respectively bypass and are supported on two double-row sprockets II 4-19 and two driven sprockets II 4-15 on the drive surface side and the operating surface side. One end of the two finished product receiving platen chains I 4-16 is fixed to the corner of the finished product receiving platen 4-23, and the other end is respectively fixedly connected to the steel wire ropes of two retractable wire reelers 4-1.
[0014] Two retractable wire reelers 4-1 are respectively fixed to the bottoms of the operating surface finished product unit support columns 4-24 and the drive surface finished product unit support columns 4-24.
[0015] Two finished product receiving platen chains II 4-21 respectively bypass and are supported on two double-row sprockets II 4-19. One end of the two finished product receiving platen chains II 4-21 is respectively fixed to the corner of the finished product receiving platen 4-23, and the other end is respectively fixedly connected to the steel wire ropes of two retractable wire reelers 4-1.
[0016] The motor II 4-17 is fixed outside the drive surface wall panel.
[0017] Optionally, the open-chain drive tension control mechanism is further improved and is used for the paper receiving unit D and / or the finished product receiving unit E of the automatic die-cutting machine.
[0018] Optionally, further improve the open chain drive tension control mechanism. During operation, Motor II 4-17 drives the main drive shaft II 4-18 to drive the double-row sprocket II 4-19 to first rotate counterclockwise and then rotate clockwise to complete a working cycle.
[0019] Optionally, further improve the open chain drive tension control mechanism. The two chains 4-21 and the two finished product receiving table chains I 4-16 are always in a tensioned state during the upward or downward movement of the finished product receiving table 4-23.
[0020] The present utility model provides an automatic die-cutting machine. The paper receiving unit D and / or the finished product receiving unit E of the automatic die-cutting machine adopt the open chain drive tension control mechanism described in any one of the above.
[0021] The working process of the present utility model is as follows;
[0022] During operation, as the finished products are continuously stacked on the finished product receiving table 4-23, Motor II 4-17 drives the main drive shaft II 4-18 to drive the double-row sprocket II 4-19 to rotate counterclockwise, driving the finished product receiving table chain II 4-21 on the right side of the double-row sprocket II 4-19 and the finished product receiving table chain I 4-16 to move upward, pulling out the steel wires fixed to one end of the finished product receiving table chain II 4-21 and the finished product receiving table chain I 4-16 on the operation surface and the transmission surface from the four retractable wire reels 4-1 respectively. When the steel wires are pulled out, they are subjected to the tensile force of the torsion springs in the retractable wire reels 4-1, so that the finished product receiving table chain II 4-21 and the finished product receiving table chain I 4-16 are in a tensioned state on the right side of the double-row sprocket II 4-19. At the same time, under the gravity of the finished product receiving table 4-23 and the stacked finished products, the two finished product receiving table chains II 4-21 and the two finished product receiving table chains I 4-16 fixed at the four corners of the finished product receiving table 4-23 and located on the left side of the double-row sprocket II 4-19 are also in a tensioned state. When the double-row sprocket II 4-19 rotates counterclockwise, the finished product receiving table chain II 4-21 on the left side of the double-row sprocket II 4-19 and the finished product receiving table chain I 4-16 bypassing the driven sprocket II 4-15 move downward synchronously, so that the finished product receiving table 4-23 continuously descends to collect and stack more finished products. When the finished product receiving table 4-23 is full of finished products, the finished product receiving table 4-23 is lowered to the lowest position and the stacked finished products are transported away.
[0023] Motor II 4-17 drives main drive shaft II 4-18, which drives double-row sprocket II 4-19 to rotate clockwise. This drives finished product receiving platform chain II 4-21 and finished product receiving platform chain I 4-16 on the left side of double-row sprocket II 4-19 upward, driving the empty finished product receiving platform 4-23 to rise to the working position for collecting finished products. At the same time, finished product receiving platform chain II 4-21 and finished product receiving platform chain I 4-16 on the right side of double-row sprocket II 4-19 move downward. The steel wire ropes attached to one end of the finished product receiving platform chain II 4-21 and the finished product receiving platform chain I 4-16 on the operating and transmission sides are continuously retracted under the tensile force of the torsion spring of the retractable wire reel 4-1, keeping the finished product receiving platform chain II 4-21 and the finished product receiving platform chain I 4-16 on the right side of the double-row sprocket II 4-19 in a constant state of tension as the finished product receiving platform 4-23 ascends. Simultaneously, under the force of gravity on the finished product receiving platform 4-23, the finished product receiving platform chain II 4-21 and the finished product receiving platform chain I 4-16, fixed to the four corners of the finished product receiving platform 4-23 on the left side of the double-row sprocket II 4-19, are also kept in a state of tension as the finished product receiving platform 4-23 ascends.
[0024] The present invention operates on the same principles when applied to the delivery section D. Motor I 4-8 drives chains 4-4 and 4-13, which raise and lower the delivery table 4-9. Finished products or scraps after collection are collected and stacked on the delivery table 4-9. The tension control mechanism for chains 4-4 and 4-13, which raise and lower the delivery table 4-9, operates on the same principle as the tension control mechanism for chains 4-16 and 4-21 driving the delivery table 4-23 in the delivery section E.
[0025] The utility model uses a retractable reel 4-1 to replace the wire rope, pulley structure, and weight structure that enclose the chain that pulls the paper delivery platen or finished product delivery platen up and down. This makes the engagement between the chain and the sprocket more stable and reduces the risk of tooth skipping when the sprocket drives the chain under heavy loads. At the same time, it greatly reduces machine failures such as wire rope fatigue fracture caused by the pulley and wire rope structure, thereby improving machine reliability.
