Description

Technical Field

[0001] This utility model relates to the field of precision die-cutting technology, specifically a precision die-cutting device. Background Technology

[0002] Die-cutting equipment is a high-precision processing device used in the printing, packaging, and manufacturing industries. It is mainly used to cut materials (such as paper, plastic, leather, self-adhesive labels, etc.) into specific shapes or contours using molds. Its core components include a die-cutting plate, an imprinting platform, and a transmission system. During operation, mechanical or hydraulic pressure is used to make the die-cutting plate contact the material to complete precise cutting or creasing. This device is widely used in label making, cardboard box forming, electronic product auxiliary material processing, and other fields, and has advantages such as high efficiency and good forming consistency.

[0003] During production, some die-cutting machines may produce wrinkles in the material, especially softer materials. Cutting without smoothing the wrinkles can lead to deviations in the product parameters and waste. Some die-cutting machines have added smoothing mechanisms, but the smoothing force is set to a fixed value. When smoothing different batches or materials, excessive smoothing force may cause deformation or tearing damage to the material, also resulting in waste. Utility Model Content

[0004] To address the aforementioned issues, this application provides a precision die-cutting device. This solves the problem that some die-cutting devices, when cutting without smoothing during production, result in deviations in the parameters of the cut products, leading to waste. Furthermore, some die-cutting devices have added smoothing mechanisms, but the smoothing force is fixed. When smoothing different batches or materials, excessive smoothing force may cause deformation or tearing damage to the materials, also resulting in waste.

[0005] A precision die-cutting device includes a conveyor belt for conveying materials, an electric push rod mounted on the top of the conveyor belt, and an extrusion plate for extruding and fixing the materials mounted below the telescopic end of the electric push rod.

[0006] Below the telescopic end of the electric push rod, there is also a smoothing plate for smoothing the material. The smoothing plate is tilted, and the bottom of the smoothing plate is higher than the bottom of the extrusion plate. The height of the smoothing plate is adjustable.

[0007] Furthermore, a support drive assembly is installed on the inner side of the conveyor belt, and a mounting frame is fixedly installed on the top of the support drive assembly, with the electric push rod fixedly connected to the mounting frame.

[0008] Furthermore, a connecting frame is fixedly installed at the telescopic end of the electric push rod, a vertical storage compartment is fixedly installed at the bottom of the connecting frame, the extrusion plate is slidably inserted into the bottom of the vertical storage compartment, and an extrusion return spring is fixedly installed between the top of the extrusion plate and the vertical storage compartment.

[0009] Furthermore, the bottom of the connecting frame has two locking pins that slide through and are inserted into it, and two connecting pins slide through and are inserted into it on the outside of the locking pins. The middle of the connecting pins has multiple mounting through holes that cooperate with the locking pins. An inclined storage compartment is fixedly installed at the bottom of the connecting pins. A smoothing plate is slidably inserted into the bottom of the inclined storage compartment. A smoothing and reset spring is fixedly installed between the top of the smoothing plate and the inclined storage compartment.

[0010] Furthermore, both the flat plate and the extrusion plate have removable extrusion components fixedly installed at their bottoms by bolts.

[0011] The beneficial effects of this utility model are as follows:

[0012] The precision die-cutting device of this utility model involves an extrusion plate first contacting the material and pressing against one end of the material, followed by a smoothing plate contacting the material. The inclined friction force drives the smoothing of the other end of the material, and the cutting component cuts the smoothed material, so that the parameters of the finished product meet the design requirements and reduce waste caused by cutting errors.

[0013] The smoothing pressure of the flat surface is adjustable, which can be adapted to more types of materials, avoiding excessive smoothing pressure that may damage the material, or insufficient smoothing pressure that may still leave wrinkles.

[0014] The friction coefficient between the bottom of the extrusion plate and the material can be controlled by replacing the extrusion parts with different materials, thus making the smoothing operation adaptable to more materials. Attached Figure Description

[0020] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0021] like Figure 1 , Figure 2 As shown, this utility model embodiment provides a precision die-cutting device, including a conveyor belt 2 for conveying materials. A support drive assembly 1 is installed on the inner side of the conveyor belt 2 to support the conveyor belt 2 and drive it to rotate. This is a relatively mature prior art, which will not be described in detail here. An electric push rod 4 is installed on the top of the conveyor belt 2 as a power source. An extrusion plate 7 for extruding and fixing materials is installed below the telescopic end of the electric push rod 4 to fix one end of the material and facilitate the subsequent smoothing of the other end of the material.

[0022] Below the telescopic end of the electric push rod 4, there is also a smoothing plate 15 for smoothing materials. The smoothing plate 15 is tilted to apply a horizontal smoothing force to the material. The bottom height of the smoothing plate 15 is higher than the bottom height of the extrusion plate 7. The extrusion plate 7 contacts the material first, fixes it first, and then smooths it. The height of the smoothing plate 15 is adjustable, thereby adjusting the smoothing force and adapting to more materials. The bottom of both the smoothing plate 15 and the extrusion plate 7 are fixed with disassembly extrusion parts 8 by bolts. The operator can control the friction coefficient between the bottom of the extrusion plate 7 and the smoothing plate 15 and the material by changing the disassembly extrusion parts 8 of different materials, thereby making the smoothing operation adaptable to more materials.

[0023] In this embodiment, the support drive assembly 1 drives the conveyor belt 2 to transport the material to be cut to the area directly below the mounting frame 3. The conveyor belt 2 stops rotating, the telescopic end of the electric push rod 4 extends, and drives the extrusion plate 7 and the flat plate 15 to move down. The extrusion plate 7 first contacts the material and presses against one end of the material.

[0024] The smoothing plate 15 contacts the material, and the inclined friction drives the other end of the material to be smoothed. The cutting component cuts the smoothed material, so that the parameters of the finished product meet the design requirements and reduce waste caused by cutting errors.

[0025] Specifically, a mounting bracket 3 is fixedly installed on the top of the support drive assembly 1, and the electric push rod 4 is fixedly connected to the mounting bracket 3.

[0026] Specifically, a connecting frame 5 is fixedly installed at the telescopic end of the electric push rod 4, and a vertical storage compartment 6 is fixedly installed at the bottom of the connecting frame 5. The extrusion plate 7 is slidably inserted into the bottom of the vertical storage compartment 6. The vertical storage compartment 6 is used to store the extrusion plate 7. A compression reset spring 9 is fixedly installed between the top of the extrusion plate 7 and the vertical storage compartment 6 to drive the extrusion plate 7 to reset.

[0027] Specifically, the bottom of the connecting frame 5 has two sliding through-insertion pins 11, and the outer side of the pins 11 has two sliding through-insertion pins 10. The middle of the connecting pins 10 has multiple through-holes 12 that cooperate with the pins 11. The bottom of the connecting pins 10 has a tilted storage compartment 13 fixedly installed. The flat plate 15 is slidably inserted into the bottom of the tilted storage compartment 13. The storage compartment 13 is used to store the flat plate 15. The top of the flat plate 15 and the tilted storage compartment 13 are fixedly installed with a flattening return spring 14, which is used to drive the flat plate 15 to return to its original position.

[0028] In this embodiment, after the cutting is completed, the telescopic end of the electric push rod 4 is shortened, the extrusion plate 7 is reset under the elastic force of the extrusion reset spring 9, the smoothing plate 15 is reset under the elastic force of the smoothing reset spring 14, and the conveyor belt 2 rotates again.

[0029] The smoothing force of the smoothing plate 15 is adjusted by the elasticity of the smoothing return spring 14, which is determined by the descent distance of the tilted storage compartment 13. The operator can pull out the locking post 11, adjust the height of the tilted storage compartment 13 and the connecting post 10, and then insert the locking post 11 back to fix the position of the tilted storage compartment 13. This device can be adapted to more types of materials, avoiding excessive smoothing force that may damage the material, or insufficient smoothing force that may still result in wrinkles.

[0030] Specific working methods:

[0031] The support drive assembly 1 drives the conveyor belt 2 to transport the material to be cut to the area directly below the mounting frame 3. The conveyor belt 2 stops rotating, the telescopic end of the electric push rod 4 extends, and the connecting frame 5, the extrusion plate 7, and the flat plate 15 move down. The extrusion plate 7 contacts the material first, and the extrusion reset spring 9 is compressed, pressing against one end of the material.

[0032] When the smoothing plate 15 comes into contact with the material, the inclined friction force drives the other end of the material to be smoothed, the smoothing return spring 14 is compressed, and the cutting component cuts the smoothed material so that the parameters of the finished product meet the design requirements and reduce waste caused by cutting errors.

[0033] After cutting is completed, the telescopic end of the electric push rod 4 shortens, the extrusion plate 7 is reset under the elastic force of the extrusion reset spring 9, the smoothing plate 15 is reset under the elastic force of the smoothing reset spring 14, and the conveyor belt 2 rotates again.

[0034] The smoothing force of the smoothing plate 15 is adjusted by the elastic force of the smoothing return spring 14, which is determined by the descent distance of the tilted storage compartment 13. The operator can pull out the locking post 11, adjust the height of the tilted storage compartment 13 and the connecting post 10, and then insert the locking post 11 back to fix the position of the tilted storage compartment 13. This device can be adapted to more types of materials, avoiding excessive smoothing force that may damage the material, or insufficient smoothing force that may still result in wrinkles.

[0035] Furthermore, workers can control the coefficient of friction between the bottom of the extrusion plate 7 and the smoothing plate 15 and the material by replacing the extrusion parts 8 with different materials, thereby enabling the smoothing operation to be adapted to more materials.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
