Description

Technical Field

[0001] The utility model relates to the technical field of die cutting machines, in particular to a vertical double-host flat-press die cutting device. Background Art

[0002] Die-cutting machines are mainly used for die-cutting (full cutting, half cutting), creasing and hot stamping, laminating, and automatic waste discharge of some corresponding non-metallic materials, self-adhesive stickers, EVA, double-sided adhesive tapes, electronics, mobile phone pads, etc. Die-cutting machines use steel knives, hardware molds, steel wires (or templates carved from steel plates), and apply a certain pressure through the embossing plate to roll and cut printed products or cardboard into a certain shape. It is an important equipment for post-printing packaging processing and molding.

[0003] Currently, the fully automatic waste removal die-cutting machines on the market can be used for large-format die-cutting. They have the characteristics of precise registration, high speed, easy operation, fast order change, stable performance, etc. However, most of them are operated by a single host. When the host has problems, it needs to be shut down for maintenance, which has a certain impact on production efficiency. Based on this, we propose a vertical dual-host flat-press die-cutting device for improvement. Utility Model Content

[0004] The main purpose of the utility model is to provide a vertical double-host flat-pressing die-cutting device, which can effectively solve the technical problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A vertical dual-host flat-press die-cutting device comprises a machine casing and a pad. A lead screw and a limit rod are rotatably connected to the inner walls of the front and rear plates of the machine casing near the two sides. Two sliders are threaded and slidably sleeved on the outer walls of the lead screw and the limit rod. A mounting plate is fixedly connected between the two sliders on the same side. Two driving cylinders are fixedly sleeved on the two mounting plates. The output ends of the two driving cylinders on the same side are fixedly connected to a knife holder, and the lower ends of the two knife holders are fixedly connected to a cutter.

[0007] As a further solution of the utility model, fixed plates are fixedly connected to the outer walls on both sides of the two knife seats, sliding rods are slidably sleeved on the four fixed plates near the front and rear positions, and pressure plates are fixedly connected to the lower ends of the two sliding rods on the same side.

[0008] As a further solution of the utility model, two springs are fixedly connected between the four fixing plates and the four pressing plates, and the eight springs are movably sleeved on the outer walls of the eight sliding rods respectively.

[0009] As a further solution of the utility model, the threads on both sides of the screw rod are in opposite directions and are symmetrically arranged, and the sliders located on the rod bodies on both sides of the screw rod are equidistant from the middle of the screw rod.

[0010] As a further solution of the utility model, extension arms are fixedly connected to the outer walls of one side of the two side panels of the machine housing, and limiting grooves are provided on the front and rear panels of the machine housing and the outer walls of the extension arms, and the pad is slidably arranged on the two limiting grooves.

[0011] As a further solution of the utility model, a plurality of driven gears are rotatably connected to the front and rear plates of the machine casing and the outer wall of the extension arm, a driving gear is rotatably provided on the inner wall of the machine casing close to the extension arm, and the driving gear and the plurality of driven gears are meshed with the pad.

[0012] As a further solution of the utility model, the distance between the driving gear and the end surface of the extension arm on the same side away from the machine housing is smaller than the straight-line distance between the two ends of the pad.

[0013] The beneficial effects of the utility model are as follows:

[0014] By setting up two main machines to run and perform dual processing operations at the same time, the production efficiency of the device can be effectively improved. At the same time, when one main machine fails, the other main machine can continue to operate to reduce the impact on production efficiency. The two sliders on both sides are driven by the screw rod to move relative to each other, and the distance between the two main machines can be adjusted, so that the position of the main machine can be adjusted according to the needs to meet the processing requirements.

[0015] Through the slide bars arranged on both sides of the knife seat and the springs sleeved on the outer walls of the slide bars, the cardboard can be pressed by the pressing plate connected to the lower end of the slide bars when the cutter cuts and recycles, so as to prevent the cardboard from being lifted up, which is practical.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-4 As shown, a vertical double-host flat-press die-cutting device includes a machine housing 1 and a pad 5. A screw rod 13 and a limit rod 15 are rotatably connected to the inner walls of the front and rear plates of the machine housing 1 near the two sides. Two sliders 14 are threaded and slidably sleeved on the outer walls of the screw rod 13 and the limit rod 15 respectively. A mounting plate 7 is fixedly connected between the two sliders 14 on the same side. Two driving cylinders 8 are fixedly sleeved on the two mounting plates 7. The output ends of the two driving cylinders 8 on the same side are fixedly connected to a knife holder 9, and the lower ends of the two knife holders 9 are fixedly connected to a cutter 10.

[0023] In this embodiment, fixed plates are fixedly connected to the outer walls on both sides of the two knife seats 9, and slide rods 11 are slidably sleeved on the four fixed plates near the front and rear positions. The lower ends of the two slide rods 11 on the same side are fixedly connected to pressure plates 16, which are used to press the cardboard flat to prevent the cardboard from being lifted up when the cutter 10 retracts.

[0024] In this embodiment, two springs 12 are fixedly connected between the four fixed plates and the four pressing plates 16 . The eight springs 12 are movably sleeved on the outer walls of the eight sliding rods 11 , and the pressing plates 16 are pressed by the reaction force of the springs 12 .

[0025] In this embodiment, the threads on both sides of the screw rod 13 are in opposite directions and symmetrically arranged, and the sliders 14 on the rod body on both sides of the screw rod 13 are equidistant from the middle of the screw rod 13, so that the rotation of the screw rod 13 can drive the two sliders 14 on the rod body to move relative to each other.

[0026] In this embodiment, extension arms 2 are fixedly connected to the outer walls of one side of the two side panels of the machine casing 1, and limiting grooves 6 are provided on the front and rear plates of the machine casing 1 and the outer walls of the extension arms 2. The pad 5 is slidably set on the two limiting grooves 6. The pad 5 slides on the limiting grooves 6 to keep it stable.

[0027] In this embodiment, a plurality of driven gears 3 are rotatably connected to the front and rear plates of the machine housing 1 and the outer wall of the extension arm 2, and a driving gear 4 is rotatably provided on the inner wall of the machine housing 1 close to the extension arm 2, and the driving gear 4 and the plurality of driven gears 3 are all meshed with the pad 5.

[0028] In this embodiment, the end face distance between the driving gear 4 and the extension arm 2 on the same side away from the machine housing 1 is smaller than the straight-line distance between the two ends of the pad 5, so that the pad 5 is always engaged with the driving gear 4, making it convenient to drive the pad 5 to move through the driving gear 4.

[0029] It should be noted that the utility model is a vertical double-host flat-pressing die-cutting device. When in use, the cardboard to be cut is placed on the pad 5, and then the motor drives the driving gear 4 to rotate, thereby driving the pad 5 to move to the specified position, and then the cylinder 8 drives the knife seat 9 to move downward, thereby driving the cutter 10 to die-cut the cardboard on the pad 5. At the same time, the cardboard is flattened by the pressing plate 16 during cutting, which can avoid the edge of the cardboard being passively lifted when the knife is lifted;

[0030] When the position of the paperboard to be cut changes before cutting, the screw rod 13 can be rotated to control the relative movement of the two sliders 14 threaded thereon, thereby driving the relative movement of the mounting plate 7, and finally adjusting the relative position of the two cutters 10, which is convenient and saves trouble.

[0031] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
