Description

Technical Field

[0001] This utility model relates to the field of die-cutting machine technology, and in particular to a pressure adjustment mechanism for a die-cutting machine. Background Technology

[0002] OCA optical adhesive is widely used in fields such as electronic equipment manufacturing. Its die-cutting quality has a critical impact on product performance. Traditional die-cutting machines face many challenges in the die-cutting process of OCA optical adhesive: On the one hand, OCA optical adhesive debris easily adheres to the die-cutting blade during cutting. This debris not only affects the subsequent die-cutting accuracy but may also lead to product appearance defects. On the other hand, the frictional heat generated during cutting will cause the die-cutting blade to heat up. When the temperature exceeds the reasonable range, OCA optical adhesive is prone to changes in viscosity or deformation, which seriously reduces product quality.

[0003] Meanwhile, the pressure adjustment mechanism of traditional die-cutting machines can usually only achieve simple pressure changes. It cannot effectively address the above-mentioned problems that occur during the die-cutting process while adjusting the die-cutting pressure. Conventional pressure adjustment methods cannot simultaneously clean and cool the die-cutting blade when controlling its lifting and lowering, making it difficult to meet the high-precision, high-quality OCA optical adhesive die-cutting requirements. Utility Model Content

[0004] This invention proposes a pressure adjustment mechanism for a die-cutting machine to solve the problems of existing die-cutting blades easily adhering to debris and the changes in the adhesiveness of OCA optical adhesive caused by cutting friction heat.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressure adjustment mechanism for a die-cutting machine, including a mounting frame, wherein the mounting frame is provided with a die-cutting blade mounting seat for mounting a die-cutting blade, and further comprising:

[0006] Adjustment components are mounted on the mounting bracket and are used to raise and lower the die-cutting blade mounting base;

[0007] An air blowing assembly is mounted on the die-cutting blade mount and is used to supply air to the die-cutting blade;

[0008] The follow-up air supply component is connected to the air blowing component. When the adjustment component drives the die-cutting knife mounting seat to move down, the follow-up air supply component synchronously supplies air to the air blowing component.

[0009] Preferably, the air blowing assembly includes an air outlet main pipe installed on the side of the die-cutting blade mounting base, and the bottom end of the air outlet main pipe is connected to a plurality of air outlet heads inclined toward the cutting edge of the die-cutting blade.

[0010] Preferably, the adjusting component includes a cylinder mounted on the top of the mounting bracket, a crossbar mounted on the bottom end of the cylinder, and a pressure strip connecting the lower end face of the crossbar and the die-cutting blade mounting seat.

[0011] Preferably, a guide rod is connected to the inner top of the mounting bracket, and the guide rod passes through the horizontal bar.

[0012] Preferably, the follow-up air supply assembly includes a piston cylinder, which is mounted on the bottom end of the guide rod via a support plate, and a piston is provided inside the piston cylinder. A piston rod is connected between the upper end face of the piston and the lower end face of the crossbar, and an air supply pipe is connected between the bottom end of the piston cylinder and the main air outlet pipe.

[0013] Preferably, an air inlet pipe is connected to the air delivery pipe, a movable baffle is hinged inside the air inlet pipe, and a stop block is fixed inside the air inlet pipe and outside the movable baffle.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] (1) By setting up an air blowing component and a follow-up air supply component, when the cylinder die-cutting knife mounting seat moves down, the crossbar will drive the piston rod to move down, thereby causing the piston to move down in the piston cylinder. This allows the air in the piston cylinder to be sent into the air outlet main pipe through the air supply pipe, and air is blown towards the cutting edge from multiple air outlets. On the one hand, it can blow away the debris adhering to the die-cutting knife, and on the other hand, it can cool down synchronously, keeping the temperature within a reasonable range, avoiding excessive heat generated by friction, and preventing the OCA optical adhesive from undergoing viscosity changes or deformation due to excessive temperature.

[0016] (2) By setting up the suction pipe, movable baffle and block, when the piston rod presses down on the piston, the movable baffle is parallel to the block to block the suction pipe, which can send the gas in the piston cylinder into the main exhaust pipe; when the piston rod moves up, the suction force will cause the movable baffle to deflect inward, so that the suction pipe opens, the air resistance encountered by the piston during the upward movement is reduced, and the external gas can flow smoothly into the piston cylinder, which is conducive to the rapid upward movement of the piston.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1-5 As shown, a pressure adjustment mechanism for a die-cutting machine includes a mounting frame 1, within which a liftable die-cutting blade mounting seat 2 is provided. The die-cutting blade mounting seat 2 is used to mount the die-cutting blade. It also includes an adjustment component 3, an air blowing assembly 5, and a follow-up air supply assembly 6. The adjustment component 3 is mounted on the mounting frame 1 and is used to raise and lower the die-cutting blade mounting seat 2. The air blowing assembly 5 is mounted on the die-cutting blade mounting seat 2 and is used to supply air to the die-cutting blade. The follow-up air supply assembly 6 is connected to the air blowing assembly 5. When the adjustment component 3 drives the die-cutting blade mounting seat 2 to move downwards, the follow-up air supply assembly 6 synchronously supplies air to the air blowing assembly 5, so as to synchronously blow air when die-cutting OCA optical adhesive.

[0030] Among them, see Figures 1-3As shown, the air blowing assembly 5 includes an air outlet main pipe 51 installed on the side of the die-cutting blade mounting base 2. The bottom end of the air outlet main pipe 51 is connected to multiple air outlet heads 52 that are inclined towards the cutting edge of the die-cutting blade. When die-cutting OCA optical adhesive, air is blown to the cutting edge through the air outlet heads 52 at the same time. On the one hand, it can blow away the debris adhering to the die-cutting blade, and on the other hand, it can cool down at the same time, control the temperature within a reasonable range, avoid excessive heat generated by friction, and prevent the OCA optical adhesive from undergoing viscosity changes or deformation due to excessive temperature.

[0031] See Figures 1-2 As shown, the adjusting component 3 includes a cylinder 31 mounted on the top of the mounting bracket 1. A horizontal bar 32 is mounted on the bottom of the cylinder 31. A pressure bar 33 is connected between the lower end face of the horizontal bar 32 and the die-cutting blade mounting seat 2. A guide rod 4 is connected to the top of the inner part of the mounting bracket 1. The guide rod 4 passes through the horizontal bar 32. The guide rod 4 can increase the stability of the horizontal bar 32 moving up and down. When adjusting the die-cutting pressure, the die-cutting pressure is adjusted by changing the input pressure of the cylinder 31. Specifically, when the input pressure of the cylinder 31 is increased, the output end of the cylinder 31 applies a greater force to the die-cutting blade mounting seat 2, so that the die-cutting blade can die-cut the OCA optical adhesive.

[0032] See Figures 3-4 As shown, the follow-up air supply assembly 6 includes a piston cylinder 61, which is mounted on the bottom end of the guide rod 4 via a support plate. A piston 62 is provided inside the piston cylinder 61. A piston rod 63 is connected between the upper end face of the piston 62 and the lower end face of the crossbar 32. An air supply pipe 64 is connected between the bottom end of the piston cylinder 61 and the main air outlet pipe 51.

[0033] As described above, in practical use, as the cylinder 31 drives the die-cutting blade mounting base 2 to move down to die-cut OCA optical adhesive, the horizontal bar 32 will drive the piston rod 63 to move down when it moves down, thereby causing the piston 62 to move down inside the piston cylinder 61. This allows the air inside the piston cylinder 61 to be sent into the air outlet main pipe 51 through the air supply pipe 64, and then air is blown towards the cutting edge from multiple air outlets 52, which can simultaneously cool down the die-cutting blade while removing debris.

[0034] In addition, see Figures 4-5 As shown, an air supply pipe 64 is connected to an air intake pipe 65. A movable baffle 66 is hinged inside the air intake pipe 65. A stop block 67 is fixed inside the air intake pipe 65 and outside the movable baffle 66. A sealing ring is provided at the edge of the movable baffle 66.

[0035] As described above, when the piston rod 63 moves down and presses down on the piston 62, the movable baffle 66 is parallel to the stop block 67, the intake pipe 65 is blocked, and the gas in the piston cylinder 61 is sent into the exhaust pipe 51. When the piston rod 63 moves up, the suction force causes the movable baffle 66 to deflect inward, which opens the intake pipe 65, allowing external gas to flow smoothly into the piston cylinder 61. Furthermore, due to the timely opening of the intake pipe 65, the air resistance encountered by the piston 62 during its upward movement is significantly reduced, which is conducive to the piston 62 moving up quickly and improves the efficiency of the entire working cycle.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
