Abstract
Description
Technical Field
[0001] This utility model relates to the field of die-cutting equipment technology, and in particular to a die-cutting mechanism for adhesive products. Background Technology
[0002] Die-cutting machines, also known as CNC punching machines, are mainly used for die-cutting, creasing, and hot stamping of non-metallic materials, self-adhesive labels, EVA, double-sided tape, electronic products, mobile phone pads, etc. During die-cutting, the machine uses a die-cutting blade to cut the product into a specific shape. However, when die-cutting adhesive products, due to the product's inherent adhesiveness, the waste material from the die-cutting process easily adheres to the die-cutting blade, affecting the blade's subsequent operation. Utility Model Content
[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a die-cutting mechanism for adhesive products that can effectively avoid the phenomenon of waste material adhesion.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a die-cutting mechanism for adhesive products, including an upper die assembly and a lower die assembly used in conjunction; the upper die assembly includes an upper die fixing seat that can move towards or away from the lower die assembly under the action of a power component, an upper template is embedded on the side of the upper die fixing seat facing the lower die assembly, and at least one die-cutting blade adapted to the shape of the product is provided on the upper template;
[0005] It also includes an air blowing assembly, which includes an airflow channel and a plurality of first air blowing holes and second air blowing holes; the airflow channel is built into the upper mold fixing base and communicates with all the first air blowing holes; the first air blowing holes are arranged on the upper mold plate along the moving direction of the upper mold fixing base; the second air blowing holes are arranged on any of the die-cutting blades along the moving direction of the upper mold fixing base and communicate with the first air blowing holes; and each die-cutting blade is provided with at least one second air blowing hole.
[0006] The product is placed on the lower mold assembly, and then the upper mold fixing seat is driven by the power component to move towards the lower mold assembly. The upper template and the die cutter move towards the lower mold assembly simultaneously until the die cutter touches the product. Gas is introduced into the airflow channel, and the gas can be blown towards the product through the first air blowing hole and the second air blowing hole. At the same time, the upper template and the die cutter continue to move towards the product. At this time, the waste material cut off by the die cutter can be removed from the die cutter under the combined action of the first air blowing hole and the second air blowing hole, thereby avoiding the phenomenon of waste material adhesion.
[0007] The beneficial effects of the die-cutting mechanism for adhesive products of this utility model are as follows:
[0008] In the air blowing assembly, the airflow channel is set inside the upper mold fixing seat, which avoids the airflow channel from affecting the movement of the upper mold plate and the die cutting blade. At the same time, the cooperation of the first air blowing hole and the second air blowing hole can supply the gas in the airflow channel to the upper mold plate and the die cutting blade, thereby preventing the waste material cut off by the die cutting blade from adhering to the die cutting blade.
[0009] Furthermore, the number of the first air blowing holes is greater than the number of the second air blowing holes, so that airflow can be directly blown onto the lower mold assembly through the first air blowing holes. In other words, some of the first air blowing holes are directly exposed on the upper mold plate. These first air blowing holes can blow air onto the product located on the lower mold assembly, thereby facilitating the product's adhesion to the lower mold assembly and improving the stability of the product's position during die cutting.
[0010] Furthermore, the diameter of the first air holes connected to the second air hole is the same, while the diameter of the first air holes not connected to the second air hole is different. The different diameters of the first air holes generate varying airflow forces on the product, resulting in different degrees of adhesion between the product and the lower mold assembly. The advantage of this design is that, near the die-cutting position, the diameter of the first air hole can be larger, resulting in a stronger adhesion force between the product and the lower mold assembly, effectively counteracting the force exerted by the die-cutting process.
[0011] Furthermore, one side of the upper mold fixing base is provided with an air passage interface that communicates with the airflow channel, and the air passage interface is connected to an air source through an air pipe. This facilitates the supply of air to the airflow channel.
[0012] Furthermore, the upper mold fixing base has a groove, the width of which is adapted to the upper template, and the length of which is greater than that of the upper template. Along the length of the groove, a first limiting post and a second limiting post are provided on both sides of the upper template. This design facilitates the replacement of the upper template according to actual needs and also provides positioning for the upper template.
[0013] Furthermore, the first and second limiting posts are staggered along the width of the groove to limit the position of the upper template at different positions in the width of the groove, which is beneficial to the stability of the upper template position.
[0014] Furthermore, the lower ends of both the first and second limiting posts are frustum-shaped, and the lower surfaces of both posts are lower than the lower surface of the die-cutting blade. The lower die assembly is also provided with limiting grooves corresponding to the first and second limiting posts. The arrangement of the first and second limiting posts and the limiting grooves allows for more accurate cutting of the die-cutting blade.
[0015] Furthermore, the lower die assembly includes a lower die fixing base, and one end of the lower die fixing base facing the upper die assembly has a cutting groove that corresponds one-to-one with the die-cutting blade; the lower end of the lower die fixing base has a waste collection port that communicates with the cutting groove. After die-cutting, the waste material can enter the waste collection port through the cutting groove.
[0016] Furthermore, the lower mold fixing seat is provided with a limiting stop bar for restricting the position of the product.
[0017] Furthermore, the upper mold fixing base is provided with guide posts around its perimeter, and the lower mold fixing base is provided with guide grooves around its perimeter that match the guide posts. The movement direction of the upper mold fixing base is guided by the cooperation of the guide posts and guide grooves. Attached Figure Description

[0026] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.
[0027] Example
[0028] See appendix Figure 1-2As shown, the present invention discloses a die-cutting mechanism for adhesive products, comprising an upper die assembly, a lower die assembly, and an air-blowing assembly. The upper die assembly includes an upper die fixing seat 11 that can move towards or away from the lower die assembly under the action of a power component. An upper template 12 is embedded in the side of the upper die fixing seat 11 facing the lower die assembly, and the upper template 12 is provided with at least one die-cutting blade 13 adapted to the shape of the product. The air-blowing assembly is located on the upper die assembly and includes an airflow channel and a plurality of first air-blowing holes 21 and second air-blowing holes 22. The airflow channel is built into the upper die fixing seat 11 and communicates with all the first air-blowing holes 21. The first air-blowing holes 21 are arranged on the upper template 12 along the moving direction of the upper die fixing seat 11. The second air-blowing holes 22 are arranged on any die-cutting blade 13 along the moving direction of the upper die fixing seat 11 and communicate with the first air-blowing holes 21. Each die-cutting blade 13 has at least one second air-blowing hole 22 penetrating through it.
[0029] The product is placed on the lower mold assembly, and then the upper mold fixing seat 11 is driven by the power component to move towards the lower mold assembly. The upper template 12 and the die cutter 13 move towards the lower mold assembly simultaneously until the die cutter 13 comes into contact with the product. Gas is introduced into the airflow channel, and the gas can be blown towards the product through the first air blowing hole 21 and the second air blowing hole 22. At the same time, the upper template 12 and the die cutter 13 continue to move towards the product. At this time, the waste material cut off by the die cutter 13 can be removed from the die cutter 13 under the combined action of the first air blowing hole 21 and the second air blowing hole 22, thereby avoiding the phenomenon of waste material adhesion.
[0030] In this embodiment, in the air blowing assembly, the airflow channel is set inside the upper mold fixing seat 11, which avoids the airflow channel from affecting the movement of the upper template 12 and the die-cutting blade 13. At the same time, the gas in the airflow channel can be supplied to the upper template 12 and the die-cutting blade 13 through the cooperation of the first air blowing hole 21 and the second air blowing hole 22, thereby preventing the waste material cut off by the die-cutting blade from adhering to the die-cutting blade 13.
[0031] Because the product is prone to movement during die-cutting due to the force exerted by the die-cutting blade 13, which may lead to a shift in the die-cutting position, in some embodiments, the number of first air holes 21 can be set to be greater than that of second air holes 22. In this case, in addition to the first air holes 21 that correspond one-to-one with the second air holes 22, some first air holes 21 will be directly exposed on the upper template 12. These first air holes 21 can blow air directly onto the lower die assembly after air is introduced, thereby applying force to the un-die-cut product and allowing the un-die-cut product parts to adhere to the lower die assembly, ensuring the stability of the product position during die-cutting.
[0032] Furthermore, the diameters of the first air holes 21 that are not connected to the second air hole 22 are different. This arrangement allows these first air holes 21 to generate different levels of airflow onto the product, resulting in varying degrees of adhesion between the product and the lower mold assembly. Near the die-cutting position, where the product is more significantly affected by the die-cutting process, the diameter of the first air holes 21 near the die-cutting position can be set larger. This allows for a correspondingly greater adhesion between the product and the lower mold assembly near the die-cutting position, thus counteracting the force exerted by the die-cutting process on the product.
[0033] For the first air hole 21 that communicates with the second air hole 22, its diameter can be set to the same diameter. Correspondingly, the diameter of the second air hole 22 is also set to the same diameter. This facilitates a relatively uniform airflow on the die-cutting part of the product (i.e., the waste material). In order to ensure that the waste material can be removed from the die-cutting blade 13, for larger die-cutting blades 13, more second air holes 22 can be provided accordingly.
[0034] In some embodiments, in order to facilitate the supply of air to the airflow channel, an air passage interface 111 communicating with the airflow channel is provided on one side of the upper mold fixing base 11, and the air passage interface 111 is connected to the air source through the air pipe 3.
[0035] In practical applications, the number and shape of die-cutting blades 13 on the upper template 12 vary depending on the product type. To facilitate replacement of the upper template 12 according to actual needs, the upper template 12 is generally detachably connected to the upper mold fixing base 11 by bolts. Specifically, in some embodiments, see the appendix. Figure 1 As shown, the upper mold fixing base 11 has a groove 112. The width of the groove 112 is adapted to the upper template 12, and the length of the groove 112 is greater than that of the upper template. Along the length of the groove 112, a first limiting post 113 and a second limiting post 114 are provided on both sides of the upper template 12. By setting the width of the groove 112 to match the size of the upper template 12, while setting the length to be greater than the size of the upper template 12, the groove 112 has a certain margin to facilitate the removal of the upper template 12 from within the groove 112, and then the upper template 12 is limited in the length direction by the cooperation of the first limiting post 113 and the second limiting post 114.
[0036] Furthermore, the first limiting post 113 and the second limiting post 114 are offset along the width direction of the groove 112 to limit the position of the upper template 12 at different positions in the width direction of the groove 112, which is beneficial to the stability of the position of the upper template 12.
[0037] In some embodiments, to improve the accuracy of the die-cutting position of the die-cutting blade 13, a limiting groove 41 corresponding to the first limiting post 113 and the second limiting post 114 can be provided on the lower die assembly, and the lower end faces of the first limiting post 113 and the second limiting post 114 are both lower than the lower end face of the die-cutting blade 13. When the upper die fixing seat 11 moves towards the lower die assembly, the first limiting post 113 and the second limiting post 114 can contact the lower die assembly before the die-cutting blade 13. Furthermore, the lower ends of the first limiting post 113 and the second limiting post 114 are both frustum-shaped to facilitate the insertion of the first limiting post 113 and the second limiting post 114 into the limiting groove 41.
[0038] In some embodiments, see Appendix Figure 3 As shown, the lower mold assembly includes a lower mold fixing base 42. The lower mold fixing base 42 has a cutting groove 421 at one end facing the upper mold assembly, corresponding to the die-cutting blade 13. A waste collection port communicating with the cutting groove 421 is provided at the lower end of the lower mold fixing base 42. A limiting groove 41 is correspondingly provided on the lower mold fixing base 42.
[0039] Furthermore, the lower mold fixing seat 42 is provided with a limiting stop 43 for limiting the position of the product, and the limiting stop 43 is provided with a clearance notch 431 for avoiding the limiting groove 41.
[0040] In order to guide the movement of the upper mold fixing seat 11, in some embodiments, guide posts 115 are provided around the upper mold fixing seat 11, and guide grooves 44 matching the guide posts 115 are provided around the lower mold fixing seat 11.
[0041] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
