Description

Technical Field

[0001] The invention relates to a cutter for screen coating and printing, in particular to an adjustable cutter die capable of adjusting the coating width of the cutter. Background Art

[0002] Screen printing is a long-established printing technology that involves applying a photosensitive emulsion to a mesh, followed by drying, exposure, and development. Finally, the excess emulsion is washed off, leaving the mesh with a mask of a specific pattern. During printing, the mask controls the ink's penetration, ensuring that the ink is printed in the desired location.

[0003] With technological advancements, screen printing is increasingly requiring precision lines, and the wire diameter of precision meshes is constantly decreasing. This also translates into an increase in the cost per unit area of ​​the mesh. To effectively utilize the mesh, the size of the pattern is considered during stencil production, adjusting the mesh and coating area accordingly.

[0004] However, the coating width of existing coating machines is tied to the die cutter; a single die cutter only supports a single coating width. When the stencil size needs to be changed to meet customer needs, the die cutter must be replaced to reduce or increase the coating width. Each die cutter replacement requires cleaning, installation, and fine-tuning, increasing the time and cost of die cutter replacement.

[0005] The inventors of this case have been actively developing new utility models that can improve the above problems, as the steps for adjusting the coating width of existing die cutters are cumbersome and increase time costs. Utility Model Content

[0006] The main purpose of the utility model is to change the coating width of the coating end by inserting a baffle into the knife die to cut off the feed flow channel, thereby saving the time of disassembling and replacing the knife die in order to adjust the coating width.

[0007] Another purpose of the present invention is to use an electric device to extend and retract the baffle in the knife die to adjust the coating width of the coating end, thereby improving the automation level of the knife die and quickly adjusting the coating width of the coating end to increase the utilization rate.

[0008] The adjustable die of the present invention comprises a die body with a coating tip disposed below the die body for applying coating to a target object. The coating tip is elongated, and the side of the die body away from the coating tip is considered the upper side. The die body comprises a first die, a second die, and a baffle. The area between the first and second dies is the inner side, and the opposite side is the outer side.

[0009] The first mold has a first inner side surface formed on its inner side and includes an injection port, a runner, and a buffer runner. The injection port is located above the first mold; the runner is located on the first inner side surface and communicates with the injection port; and the buffer runner is located on the first inner side surface and is closer to the coating end than the runner. The second mold is connected to the first mold and has a second inner side surface adjacent to the first inner side surface. The second mold is provided with a baffle insert that connects the second inner side surface to the outside world.

[0010] In a preferred embodiment of the present invention, a flow channel is formed by a gap between the first inner side surface and the second inner side surface. Furthermore, the flow channel connects the runner, the buffer runner, and the coating end, allowing a user to add coating from the injection port and flow it into the runner, the runner, the buffer runner, and the coating end.

[0011] In a preferred embodiment of the present invention, the baffle insert is connected to the flow channel, and the baffle is inserted to cut off the flow channel, thereby stopping the coating end at the corresponding position. Specifically, the user can use baffles of different widths to change the coating width or coating position of the coating end, and can also use multiple baffles simultaneously.

[0012] In a preferred embodiment of the present invention, the baffle is connected to the second inner side surface and the second outer side surface opposite to the other side, thereby facilitating the disassembly and assembly of the baffle.

[0013] Preferably, one end of the baffle insert on the second outer side surface is higher than one end of the second inner side surface, so as to prevent the coating agent from flowing out from the flow channel through the baffle insert.

[0014] In a preferred embodiment of the present invention, the runner, the buffer runner and the flow channel extend to the left and right sides of the tool body, thereby forming a baffle socket.

[0015] In a preferred embodiment of the present invention, the baffle can be connected to an electric device having an electric control system and a reciprocating mechanism, wherein the electric control system supplies power and controls the actuation of the reciprocating mechanism; and the reciprocating mechanism is connected to the baffle.

[0016] In a preferred embodiment of the present invention, the electric device controls the baffle to move in the knife die body, thereby shortening or increasing the coating width of the coating end.

[0017] Preferably, the cross-sectional shape of the baffle is the same as the cross-sectional shape formed by the runner, the buffer runner and the flow channel.

[0018] Preferably, the baffle is composed of two pieces, which can cooperate with an electric device to adjust the coating width of the nozzle from the left and right side pieces of the knife die body.

[0019] Preferably, the coating width of the nozzle is 10 to 300 mm. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] To facilitate understanding of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and embodiments. The accompanying drawings provide some, but not all, embodiments of the present invention. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any progressive efforts are within the scope of protection of the present invention.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0042] Figures 1 to 5 Schematic diagram of an embodiment of the present utility model, as shown in FIG. Figure 1 As shown in the exploded schematic diagram of the first embodiment of the present invention, the adjustable die plate of the present invention comprises a die plate body 1. A coating tip 10 is disposed below the die plate body 1 for applying coating to an object. The coating tip 10 is elongated, and the side of the die plate body 1 away from the coating tip 10 is considered the upper side. The die plate body 1 comprises a first die 11, a second die 12, and a baffle 13. The area between the first die 11 and the second die 12 is the inner side, and the opposite side is the outer side.

[0043] The first mold 11 is formed with a first inner side surface 110 on its inner side, and includes an injection port 111, a runner 112, and a buffer runner 113. The injection port 111 is located above the first mold 11; the runner 112 is located on the first inner side surface 110 and communicates with the injection port 111; and the buffer runner 113 is located on the first inner side surface 110 and is closer to the coating end 10 than the runner 112. The second mold 12 is connected to the first inner side surface 110 and has a second inner side surface 1201 formed thereon, adjacent to the first inner side surface 110. The second mold 12 is provided with a baffle insert 121 connected to the second inner side surface 1201.

[0044] like Figure 2 of Figure 1 As shown in the cross-sectional view of the first embodiment of the present invention taken along the II-II direction, a flow channel 114 is formed between the first inner side surface 110 and the second inner side surface 1201. Furthermore, the flow channel 114 connects the runner 112, the buffer runner 113, and the coating end 10, allowing the user to add paint from the injection port 111 and flow it into the runner 112, the flow channel 114, the buffer runner 113, and the coating end 10.

[0045] When applied preferably, Figure 2 As shown, the baffle slot 121 connects to the flow channel 114, allowing the insertion of a baffle 13 to block the flow channel 114 and stop the coating end 10 at the corresponding position. Specifically, the user can insert baffles 13 of different widths into the baffle slot 121 to block the coating end 10's supply. This allows the coating width or coating position of the coating end 10 to be changed, and multiple baffles 13 can be used simultaneously for adjustment.

[0046] In a preferred embodiment of the present invention, the baffle opening 121 communicates with the second inner side 1201 and the second outer side 1202 opposite the second inner side 1201. The operator can insert the baffle 13 according to the width of the target object, thereby adjusting the coating width of the coating end 10. Specifically, when the target object is smaller than the coating width of the lower coating end 10, the operator inserts the baffle 13 into the baffle opening 121, blocking the left and right flow channels 114, thereby stopping the coating end 10 from feeding the material, thereby shortening the coating width.

[0047] Preferably, one end of the baffle socket 121 on the second outer side surface 1202 is higher than one end of the second inner side surface 1201 .

[0048] like Figure 3 As shown in the three-dimensional schematic diagram of the second embodiment of the present invention, the runner 112, the buffer runner 113 and the runner 114 extend toward the left and right sides of the die body 1, forming baffle sockets 121 on the left and right sides of the die body 1.

[0049] like Figure 4 The third embodiment of the present invention is shown in a sectional perspective view, based on Figure 3 The structure of the second embodiment shown is further combined with an electric device to control the movement of the baffle 13; wherein, the baffle 13 can be connected to the electric device, which has an electric control system (not shown in the figure) and a reciprocating mechanism 2, the electric control system supplies power and controls the actuation of the reciprocating mechanism 2; and the reciprocating mechanism 2 is connected to the baffle 13.

[0050] When applied preferably, Figure 5 As shown in the schematic diagram of the third embodiment of the present invention, the electric device controls the actuation of the reciprocating mechanism 2, thereby manipulating the movement of the baffle 13 within the die body 1. Specifically, as the baffle 13 moves along the flow channel 114 within the die body 1, the baffle 13 directly cuts off the material supply to the coating end 10 during movement, thereby changing the coating width of the coating end 10.

[0051] In a preferred embodiment of the present invention, the cross-sectional shape of the baffle 13 is the same as the cross-sectional shape of the baffle socket 121 formed by the runner 112 , the buffer runner 113 and the runner 114 .

[0052] Preferably, the baffle 13 is composed of two pieces, which can cooperate with the electric device to move closer to or farther away from the left and right sides of the cutter die body 1 toward the center of the cutter die body 1, thereby adjusting the coating width of the coating end 10.

[0053] Preferably, the coating width of the coating end 10 is 10 to 300 mm.

[0054] The above-described embodiments merely represent preferred embodiments of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the claims of the present invention. It should be noted that a person skilled in the art would be able to make numerous modifications and improvements without departing from the spirit of the present invention, and such modifications and improvements are fully within the scope of protection of the present invention.
