Description

Technical Field

[0001] The utility model belongs to the technical field of die cutting, and in particular relates to an adjustable feeding device for die cutting of printed matter. Background Art

[0002] Printed products need to be prepared into a certain shape according to the requirements, that is, using the die-cutting process, the printed products are fed into the die-cutting machine under the action of the internal pressure to cut the printed products into the required shape or cut marks. When the printed products are fed into the die-cutting machine, the position must be accurate, and the feeding process cannot be offset. However, although there are positioning devices to assist in feeding, the surface of the printed products cannot be flattened in time and is difficult to adjust. This can easily lead to poor die-cutting accuracy during the die-cutting process.

[0003] In the prior art, there is a patent application numbered CN202122864142.0 that discloses an adjustable device for die-cutting feed of printed matter. The patent feeds the material through the feed conveyor platform of the die-cutting machine. The first lifting cylinder drives the first adjustment plate downward, and the pressing wheel on the pressure rod presses and positions the paper being conveyed to prevent displacement. Since a positioning spring is provided, the movable range of the pressing wheel is increased and adjustable to ensure that it can match printed matter papers of different thicknesses. At the same time, the rotating motor on the second adjustment plate drives the pressure plate to rotate. Since a universal bearing is provided on the pressure plate, the printed matter being conveyed is rotated to improve the flatness of the surface of the printed matter. Moreover, since the second adjustment plate is connected to the feed conveyor platform of the die-cutting machine through a spring rod, the height position of the second adjustment plate is automatically adjusted through the telescopic force of the spring rod in accordance with the paper thickness of the printed matter.

[0004] However, in the actual working process, whether it is using multiple pressure wheels to press and position the paper being transported, or using a rotating motor to drive the pressure plate to rotate, since the pressure plate is provided with a universal bearing, the printed matter being transported is rotated to improve the flatness of the printed matter surface, which will cause the printed matter to produce wrinkles perpendicular to the moving direction during the transmission process. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the utility model provides an adjustable device for die-cutting feed of printed matter, which has the effect of smoothing materials of different widths by adjusting the structure according to the different widths of the materials.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for adjustable die-cutting feeding of printed matter, comprising a fixed frame, both sides of which are provided with transmission belts for transmission, an upper cutter is provided on the fixed frame for lifting and driving, and a lower cutter is fixedly provided on the fixed frame at the bottom end of the upper cutter;

[0007] The upper cutter moves downward, so that a shearing motion is formed between the upper cutter and the lower cutter, thereby achieving shearing of the paper on the transmission belt.

[0008] The upper cutter is provided with an adjustable feeding device, the adjustable feeding device comprises a mounting plate which can be adjusted to rise and fall with the upper cutter, a fixed plate is provided above the mounting plate, a plurality of fixed rods which are arranged at equal intervals in a circle are fixedly provided around the fixed plate, the fixed rods are fixedly connected to the mounting plate, a shaft cylinder is provided above the fixed plate, a screw is provided for the upper limit rotation connection of the shaft cylinder, the screw is threadedly connected to the fixed plate, four hinged rods are provided for the upper limit rotation connection of the shaft cylinder, and a spring is provided for the fixed connection between the mounting plate and the hinged rod;

[0009] The spring pulls the hinged rod to have a movement tendency toward the fixed rod, so that the hinged rod has a tendency to be squeezed on the fixed rod. The screw rod is threadedly connected to the fixed disk. The distance between the shaft tube and the fixed disk is adjusted by rotating the screw rod, so that the guide rod can slide in the fixed disk to adjust the inclination angle of the hinged rod.

[0010] The hinged rod is telescopically and slidably connected with a slide rod, and an end of the slide rod away from the hinged rod is fixed with a fixed block, and the fixed block is rotatably mounted with a roller at an upper limit position.

[0011] By adjusting the length of the sliding rod extending on the hinged rod, the materials of different widths can be leveled and adjusted. The feed adjustable device moves downward with the upper cutter, and the rollers are squeezed on the material in the directions around the position to be cut. As the upper cutter continues to descend, the spring is stretched, and the hinged rod rotates upward relative to the shaft tube, and the rollers are squeezed on the material and move away from the direction to be cut. At the same time, the hinged rod rotates relative to the shaft tube, and the spring is stretched, so that the material can be pulled flat, solving the technical problems raised in the technical background.

[0012] Optionally, a locking bolt is threadedly mounted on the upper side of the sliding rod, and the locking bolt passes through the sliding rod and is squeezed onto the end surface of the hinged rod.

[0013] By loosening the locking bolt on the slide bar, the slide bar is allowed to slide on the hinged rod, thereby realizing the extension and retraction of the slide bar on the hinged rod, and adjusting the overall width of the hinged rod and the slide bar according to the actual width of the material.

[0014] Optionally, threaded barrels are vertically penetrated and fixedly provided on both sides of the upper end surface of the mounting plate, and bolts are provided on the upper end surface of the upper cutter near both sides for limited rotation connection, and the bolts are threadedly connected to the threaded barrels;

[0015] By rotating the bolt, the bolt moves up and down in the threaded barrel, and the bolt and the upper cutter rotate in a limited position, thereby adjusting the overall height of the feed adjustable device, thereby adjusting the length of the roller moving on the material during the downward pressing process of the upper cutter.

[0016] Optionally, a plurality of guide rods arranged at equal intervals on a circumference are fixedly disposed at the bottom end of the shaft cylinder, and the guide rods pass through the fixed plate and are adapted to be slidably connected with the fixed plate;

[0017] The stable adaptation and sliding of the guide rod on the fixed rod achieves the stability of the lifting and lowering of the shaft cylinder relative to the fixed rod. The threaded connection between the screw rod and the fixed disk is achieved by rotating the screw rod, so that the distance between the shaft cylinder and the fixed disk can be stably adjusted.

[0018] Optionally, the roller includes a rotating shaft connected to the fixed block in a limited rotation manner, a friction wheel is sleeved on the outer side of the rotating shaft, an internal threaded barrel is fixedly provided through one side of the fixed block, a cylindrical plastic block and a thrust spring are installed in the internal threaded barrel, a tightening bolt is also threadedly provided in the internal threaded barrel, and the thrust spring is located between the cylindrical plastic block and the tightening bolt;

[0019] The cylindrical plastic block is squeezed by the elastic force of the thrust spring so that the cylindrical plastic block is squeezed on the side of the rotating shaft, thereby providing friction to the rotating shaft, so that the roller can provide pulling force to the material when the roller rolls on the material. The tightening bolt is threadedly connected with the internal threaded barrel by rotating the tightening bolt, so that the tightening bolt can move on the internal threaded barrel, thereby adjusting the force of the thrust spring squeezing the cylindrical plastic block and changing the friction to which the rotating shaft is subjected during the rotation process.

[0020] Optionally, the friction wheel is made of rubber.

[0021] The friction wheel is made of rubber material, so that the friction wheel provides friction to the material.

By loosening the locking bolt on the slide rod, the slide rod slides on the articulated rod, and the slide rod is extended and retracted on the articulated rod. The overall width of the articulated rod and the slide rod is adjusted according to the actual width of the material, thereby solving the technical problems raised in the technical background.

[0032] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0033] Example 1: Reference Figure 1-Figure 5 , a device for adjusting the feeding of printed matter die-cutting, comprising a fixed frame 10, transmission belts 11 are installed at both sides of the fixed frame 10, vertical poles 12 are fixed at the upper ends of both sides of the fixed frame 10, an upper cutter 13 is installed between the two vertical poles 12, a hydraulic cylinder 14 is connected between the two ends of the upper cutter 13 and the vertical poles 12, a cylinder body of the hydraulic cylinder 14 is fixedly connected to the vertical poles 12, a piston rod of the hydraulic cylinder 14 is fixedly connected to the upper cutter 13, and a lower cutter 15 is fixedly provided at the bottom end of the upper cutter 13 on the fixed frame 10;

[0034] The upper cutter 13 is pushed downward by the extension of the hydraulic cylinder 14 , so that a shearing motion is formed between the upper cutter 13 and the lower cutter 15 , thereby achieving shearing of the paper on the transmission belt 11 .

[0035] An adjustable feeding device is installed on the upper end surface of the upper cutter 13, and the adjustable feeding device includes a mounting plate 21 that can be adjusted to rise and fall with the upper cutter 13, a fixed plate 24 is arranged above the mounting plate 21, and a plurality of fixed rods 25 arranged at equal intervals in a circle are fixedly arranged around the fixed plate 24, and the fixed rods 25 are fixedly connected to the mounting plate 21, and a shaft cylinder 26 is arranged above the fixed plate 24, and a screw 40 is provided for the upper limit rotation connection of the shaft cylinder 26, and the screw 40 is threadedly connected to the fixed plate 24, and four hinged rods 27 are provided for the upper limit rotation installation of the shaft cylinder 26, and a spring 28 is fixedly connected between the mounting plate 21 and the hinged rod 27;

[0036] The spring 28 pulls the articulated rod 27 to have a movement tendency toward the fixed rod 25, so that the articulated rod 27 has a tendency to be squeezed on the fixed rod 25. The screw 40 is threadedly connected to the fixed disk 24. The distance between the shaft tube 26 and the fixed disk 24 is adjusted by rotating the screw 40, so that the guide rod 32 can slide in the fixed disk 24 to adjust the inclination angle of the articulated rod 27.

[0037] The hinge rod 27 is telescopically and slidably connected with a slide rod 29 , and a fixed block 31 is fixedly provided at the end of the slide rod 29 away from the hinge rod 27 . A roller 50 is rotatably mounted on the fixed block 31 at an upper limit position.

[0038] By adjusting the length of the slide bar 29 extending on the hinged rod 27, the materials of different widths can be leveled and adjusted. The feed adjustable device moves downward with the upper cutter 13, and the roller 50 is squeezed on the material in the surrounding directions of the position to be cut. As the upper cutter 13 continues to descend, the spring 28 is stretched, and the hinged rod 27 rotates upward relative to the shaft cylinder 26.

At the same time, the hinged rod 27 rotates relative to the shaft cylinder 26, and the spring 28 is stretched to achieve the pulling and flattening of the material.

[0039] In this embodiment, a locking bolt 30 is threadedly mounted on the upper side of the sliding rod 29 , and the locking bolt 30 passes through the sliding rod 29 and is pressed onto the end surface of the hinge rod 27 .

[0044] By means of the stable adaptive sliding of the guide rod 32 on the fixed rod 25, the stability of the lifting and lowering of the shaft cylinder 26 relative to the fixed rod 25 is achieved. By rotating the screw rod 40 and the threaded connection between the screw rod 40 and the fixed disk 24, the stable adjustment of the distance between the shaft cylinder 26 and the fixed disk 24 is achieved.

[0045] Example 2: Reference Figure 6-Figure 7 The difference between this embodiment and the first embodiment is that the roller 50 includes a rotating shaft 51 that is connected to the fixed block 31 for limited rotation, a friction wheel 52 is sleeved on the outer side of the rotating shaft 51, an internal threaded barrel 61 is fixedly provided through one side of the fixed block 31, a cylindrical plastic block 62 and a thrust spring 63 are installed in the internal threaded barrel 61, a tightening bolt 64 is also threadedly provided in the internal threaded barrel 61, and the thrust spring 63 is located between the cylindrical plastic block 62 and the tightening bolt 64;

[0046] The cylindrical plastic block 62 is squeezed by the elastic force of the thrust spring 63, so that the cylindrical plastic block 62 is squeezed on the side of the rotating shaft 51, thereby providing friction to the rotating shaft 51, so that the roller 50 can provide pulling force to the material when rolling on the material. By rotating the tightening bolt 64, the tightening bolt 64 and the internal threaded tube 61 are threadedly connected, so that the tightening bolt 64 can move on the internal threaded tube 61, thereby adjusting the force of the thrust spring 63 squeezing the cylindrical plastic block 62, and changing the friction to which the rotating shaft 51 is subjected during the rotation process.

[0047] Furthermore, the friction wheel 52 is made of rubber.

[0048] By using the rubber material for the friction wheel 52 , the friction wheel 52 can provide friction force to the material.
