Abstract
Description
Technical Field
[0001] This utility model relates to the field of die-cutting technology, and in particular to a general-purpose circular die-cutting device. Background Technology
[0002] Currently, the rotary cutting machines on the market are available in 250 / 350 / 450 models. The 250 model can only produce products with a width of 250mm or less, the 350 model is generally used to produce products with a width of 250mm to 350mm, and the 450 model is generally used to produce products with a width of 350mm to 450mm. If a 450 model rotary cutting machine is used directly to produce products with a width of 250mm to 350mm or less, the product has a large range of motion in the width direction during production, which can easily cause significant deviations in the product, making it impossible to guarantee product quality. After purchasing a large-scale (450 model) rotary cutting machine, since large-sized products are often relatively few, the machine is often left idle after a batch of large-sized products is produced. Utility Model Content
[0003] The purpose of this utility model is to provide a universal circular die-cutting device to solve the technical problems existing in the background art.
[0004] To achieve the above objectives, the technical solution of this utility model is as follows:
[0005] A universal rotary die-cutting machine includes: a base, vertical plates, a bottom roller, a rotary cutter, and a U-shaped limiting block. Two vertical plates are symmetrically arranged on the left and right sides of the top of the base. A rotary cutter and a bottom roller are respectively arranged on the upper and lower sides between the two vertical plates. The rotary cutter can die-cut products with a width of 350mm to 450mm. The rotary cutter and the bottom roller cooperate to die-cut the product. A U-shaped limiting block is arranged at the top of the base between the two vertical plates, which can move left and right to limit the displacement of the product in the width direction.

The bottom end of the drive bevel gear is coaxially and fixedly connected to the output shaft of the motor. The motor is fixedly mounted on the right vertical plate via the motor mounting base.
[0009] Furthermore, the arc groove of the U-shaped limiting block is located below the bottom roller and the diameter of the arc groove is larger than the diameter of the bottom roller. The inner wall of the rectangular groove above the arc groove of the U-shaped limiting block does not contact the round roller cutter and the bottom roller. The top of the U-shaped limiting block is located above the product.
[0010] Furthermore, two sets of roller brackets are symmetrically arranged on the front and rear sides above the U-shaped limiting block. Each set of roller brackets has two rollers symmetrically arranged vertically. The two roller brackets on the same front and rear sides are rotatably connected to each other by roller shafts. The upper and lower ends of the rollers are located on the upper and lower sides of the gap between the circular roller cutter and the bottom roller.
[0011] Furthermore, it also includes: two bolts, a fixing seat, three bearings, two screws, and two rotating handles. Two bolts are provided. The fixing seat is fixedly installed on the top of the base near the lower gear by two bolts. Two bearings are provided.

[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] The U-shaped limit block, which can be adjusted left and right, can effectively limit the displacement of the die-cut product in the width direction. This allows the rotary cutter to be adjusted from being able to die-cut products with a width of 350mm to 450mm to being able to die-cut products with a width of less than 450mm, thus avoiding the idleness of the large-scale (450-type) machine.

[0026] In this embodiment, the arc groove of the U-shaped limiting block 20 is located below the bottom roller 6 and the diameter of the arc groove is larger than the diameter of the bottom roller 6. The inner wall of the rectangular groove above the arc groove of the U-shaped limiting block 20 does not contact the circular roller cutter 9 and the bottom roller 6. The top of the U-shaped limiting block 20 is located above the product, which ensures that the displacement in the width direction of the product can be limited while avoiding contact between the U-shaped limiting block 20 and the circular roller cutter 9 and the bottom roller 6.
[0027] In this embodiment, two sets of roller brackets 21 are symmetrically arranged on the front and rear sides above the U-shaped limiting block 20.

The upper and lower ends of the rollers 23 are located on the upper and lower sides of the gap between the circular roller cutter 9 and the bottom roller 6. The rollers 23 can transform the sliding friction that the product may generate with the U-shaped limiting block 20 into rolling friction with the rollers 23, thus ensuring the quality of the product.
[0028] In this embodiment, the general-purpose circular die-cutting equipment also includes: bolt 24, fixed seat 25, bearing 26, screw 27, and rotating handle 28. Two bolts 24 are provided.

The screw 27 passes through and is threadedly connected to the lower middle part of the U-shaped limiting block 20. By rotating the rotating handle 28, the U-shaped limiting block 20 can be moved left and right, thereby adapting to products of different widths.
[0029] In this embodiment, the general-purpose circular die-cutting equipment also includes: slide rod 29, two slide rods 29 are provided, and two sliding holes are symmetrically opened in front and behind the U-shaped limiting block 20. The two slide rods 29 slide through the two sliding holes respectively. The left and right ends of the two slide rods 29 are fixedly connected to the right end of the left vertical plate 2 and the left end of the fixed seat 25 respectively. The slide rods 29 can distribute the force on the screw 27.
[0030] When using this device, first adjust the U-shaped limiting block 20 to a suitable position according to the width of the product to be die-cut. Then, adjust the gap between the cylindrical cutter 9 and the bottom roller 6 according to the thickness of the product through the gap adjustment component. Then, place the product to be die-cut between the cylindrical cutter 9 and the bottom roller 6, and start the motor 18 to die-cut the product through the cylindrical cutter 9 and the bottom roller 6. The U-shaped limiting block 20, which can be adjusted left and right, can effectively limit the displacement of the product in the width direction, thereby adjusting the cylindrical cutter 9 from being able to die-cut products with a width of 350mm to 450mm to being able to die-cut products with a width of less than 450mm, thus avoiding the idleness of the large-scale (450-type) machine.
