Description

Technical Field

[0001] This utility model relates to the field of die-cutting equipment technology, and in particular to a die-cutting tool for digital electronic protective films. Background Technology

[0002] As a key component in the consumer electronics field, protective films for digital electronic products mainly rely on die-cutting equipment for molding and processing. Die-cutting equipment uses high-precision blades to punch and cut rolls or sheets of protective film material to obtain products of the required shape and size.

[0003] In continuous production, the cutting edge will wear down due to long-term use, or it may need to be frequently replaced with different specifications of cutting edge to meet the production needs of different product models. The existing cutting edge is usually fixed to the drive mechanism by multiple bolts or complex clamps. When replacing the cutting edge, the operator needs to use special tools to loosen and disassemble the fasteners one by one, and then install and tighten them one by one after the replacement is completed. The whole process is cumbersome and time-consuming, which increases the downtime of the equipment and directly reduces the overall efficiency of the production line.

[0004] In addition, the substrate of digital electronic protective films is mostly made of polymer materials. During high-speed punching, fine substrate debris is generated. These debris are sticky or carry static electricity and will adhere to the edge of the blade or tiny gaps. The accumulation of debris will not only accelerate the abnormal wear of the blade and shorten the service life of the tool, but also affect the edge quality of the protective film product in subsequent cutting, producing burrs or indentations, and reducing the product qualification rate.

[0005] Therefore, this utility model proposes a digital electronic protective film die-cutting tool to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems existing in the digital electronic protective film die-cutting tool, such as cumbersome and time-consuming tool changing process, which affects production efficiency, and the fact that the debris generated during the cutting process contaminates and accelerates blade wear, affecting product quality, this utility model aims to provide a digital electronic protective film die-cutting tool with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a digital electronic protective film die-cutting tool, including: an operating table, a blade, and a cylinder; a quick-release mechanism disposed between the blade and the cylinder; and a cleaning mechanism disposed on the operating table.

[0008] The quick-release mechanism includes a fixed base, a connecting block, bolts, a rotating column, a locking block, a first limiting rod, and a second limiting rod. The cleaning mechanism includes a base, a motor, a slide rod, a first rotating rod, a slider, a slide rail, a second rotating rod, and a vacuum cleaner.

[0009] Furthermore, the fixed base is fixed to the blade, the connecting block is fixed to the cylinder output end, the bolt passes through the fixed base and is rotatably connected to the rotating column, the outer wall of the rotating column is fixedly connected to the limiting rod one and the limiting rod two, and the locking block is detachably engaged with the limiting rod two; the motor drives the rotating rod two to rotate, and the rotating rod two drives the vacuum cleaner to reciprocate along the slide rail and the slide rod via the rotating rod one and the slider.

[0010] Preferably, the connecting block and the fixed seat are provided with grooves for guiding the first limiting rod and the second limiting rod, and the inner wall of the groove is used to limit the rotation of the rotating column.

[0011] Preferably, the locking block is provided with an integrally formed through groove and a locking groove, and the locking block achieves selective engagement between the limiting rod and the through groove or the locking groove by rotation.

[0012] Preferably, the shank of the bolt is rotatably connected to the bottom wall of the rotating column, and the rotation of the bolt drives the rotating column to move axially along the inner wall of the connecting block and the fixed seat.

[0013] Preferably, the base of the cleaning mechanism is fixed to the operating table, the slide rail is provided on the top wall of the base, and the two ends of the slide rod are fixedly connected to the base.

[0014] Preferably, the motor and the second rotating rod are combined by a fixed connection, and the second rotating rod and the first rotating rod are combined by a rotatable connection.

[0015] Preferably, the rotating rod and the slider are combined by a rotatable connection, and the slider is slidably mounted on the rotating rod.

[0016] Preferably, the vacuum cleaner is fixed on the slider, and the bottom of the vacuum cleaner is provided with a structure that slides and engages with the slide rail.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model, by setting up a quick-release mechanism consisting of a bolt, a rotating column, a limiting rod, and a locking block working in coordination, transforms the rotation of the bolt into the locking or disengaging action of the locking block. This solves the problems of complex, time-consuming, and labor-intensive tool changing processes in the prior art, which affect production efficiency. It achieves the goal of quickly disassembling and assembling the cutting edge without complicated tools, significantly shortening downtime for maintenance, improving tool changing efficiency, and increasing the overall utilization rate of the equipment.

[0019] 2. This utility model, by setting up a cleaning mechanism driven by a motor-driven connecting rod and slider, and guided by a slider and rail, drives the vacuum cleaner to automatically reciprocate below the cutting area. This solves the problem in the prior art that cutting debris easily adheres to the blade, accelerates blade wear, shortens service life, and affects product cutting quality. It achieves continuous automatic removal of cutting debris, effectively preventing debris from contaminating the blade, thereby reducing blade wear, extending service life, and ensuring die-cutting accuracy and product yield.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] Example:

[0028] Please refer to Figures 1 to 4This utility model provides a digital electronic protective film die-cutting tool, which aims to solve the problems of complex tool changing process, low efficiency and tool wear and shortened life caused by cutting debris contamination in the prior art.

[0029] like Figure 1 and Figure 2 As shown, a digital electronic protective film die-cutting tool includes an operating table 1, a cylinder 5, a blade 4, a quick-release mechanism 2 for connecting the blade 4 and the cylinder 5, and a cleaning mechanism 3 for the operating table 1. The operating table 1 serves as the mounting base for the entire device. The cylinder 5 drives the blade 4 to perform reciprocating cutting motion. The quick-release mechanism 2 is located between the blade 4 and the cylinder 5 to achieve a detachable connection between the blade 4 and the output end of the cylinder 5. The cleaning mechanism 3 is used to automatically clean the debris generated during the cutting process of the blade 4. The base 305 of the cleaning mechanism 3 is fixedly installed on the operating table 1. The quick-release mechanism 2 includes a fixed seat 202 and a connecting block 203. The fixed seat 202 is fixedly connected to the top of the blade 4 by screws, and the connecting block 203 is fixedly connected to the output end of the cylinder 5. The connecting block 203 and the fixed seat 202 are locked or separated by internal bolts 206, rotating columns 207, locking blocks 201, limit rod one 204, and limit rod two 205. Structure 3 includes a motor 301, a slide rod 302, and a slide rail 306 fixed on a base 305. The output end of the motor 301 is fixedly connected to a second rotating rod 307. The end of the second rotating rod 307 away from the motor 301 is rotatably connected to a first rotating rod 303. The end of the first rotating rod 303 away from the second rotating rod 307 is rotatably connected to a slider 304. The slider 304 is slidably fitted onto the slide rod 302. A vacuum cleaner 308 is fixedly mounted on the slider 304. The bottom of the vacuum cleaner 308 is provided with a sliding engagement with the slide rail 306. The structure has two ends of the slide rod 302 fixedly connected to the base 305, and the slide rail 306 is located on the top wall of the base 305. The motor 301 drives the rotating rod 307 to rotate, the rotating rod 307 drives the rotating rod 303 to swing, and the rotating rod 303 in turn drives the slider 304 to slide on the slide rod 302. The vacuum cleaner 308 fixed on the slider 304 performs a stable reciprocating linear motion under the guidance of the slide rail 306, thereby continuously cleaning the debris in the cutting area below the blade 4.

[0030] Please refer to Figure 3One end of the connecting block 203 of the quick-release mechanism 2 is inserted into the mating cavity of the fixed seat 202. The connecting block 203 and the interior of the fixed seat 202 together form a channel for accommodating the bolt 206 and the rotating column 207. The bolt 206 passes through the fixed seat 202 and is rotatably connected to the bottom wall of the rotating column 207. When the bolt 206 is rotated, the head of the bolt 206 abuts against the end face of the fixed seat 202, thereby driving the rotating column 207 to move linearly along the axial direction of the channel. The inner walls of both the connecting block 203 and the fixed seat 202 are provided with guide grooves. Limiting rod one 204 and limiting rod two 205 are fixedly connected to the outer wall of the rotating column 207. Limiting rod one 204 and limiting rod two 205 are slidably accommodated in the corresponding grooves. The inner wall of the groove restricts the rotation of the rotating column 207 during axial movement, ensuring smooth linear movement. The locking block 201 is positioned perpendicular to the moving direction of the rotating column 207. The locking block 201 has a through groove and a locking groove. During disassembly, the rotating column 207 moves the limiting rod 205 to a specific position, causing the locking block 201 to rotate and align the limiting rod 205 with the through groove, thus allowing the locking block 201 to be removed. During installation, the locking block 201 is inserted and rotated, aligning the limiting rod 205 with the locking groove. Then, the bolt 206 is rotated in the opposite direction, pulling the rotating column 207 backward. The rotating column 207, through the limiting rod 205, firmly presses the locking block 201 into the defined groove of the fixed seat 202. This linkage structure of the bolt 206, guide rod, and irregularly shaped locking block 201 ensures a fast, reliable, and stable connection between the blade 4 and the cylinder 5.

[0031] Please refer to Figure 4 The base 305 of the cleaning mechanism 3 is fixed on the operating table 1. The motor 301 is fixedly installed on one side of the base 305. The slide rod 302 and the slide rail 306 are both fixedly installed on the top wall of the base 305. The slide rod 302 and the slide rail 306 are arranged parallel to each other. The output end of the motor 301 is fixedly connected to one end of the rotating rod 307. The other end of the rotating rod 307 is rotatably connected to one end of the rotating rod 303 through a pin. The other end of the rotating rod 303 is rotatably connected to the slider 304 through a pin. The slider 304 has a through hole that slides with the slide rod 302. The vacuum cleaner 308 is fixed. Connected to the top of the slider 304, the bottom of the vacuum cleaner 308 has a structure that slides and engages with the slide rail 306. When the motor 301 rotates, the second rotating rod 307 acts as a crank to perform circular motion, and through the first rotating rod 303 acting as a connecting rod, the rotational motion is converted into the reciprocating linear sliding of the slider 304 on the slide rod 302. Driven by the slider 304, the vacuum cleaner 308 is guided and supported by the slide rail 306, thereby performing a stable and smooth reciprocating cleaning motion in the area below the blade 4, ensuring the accuracy of the vacuum cleaner 308's movement trajectory and the reliability of the cleaning process.

[0032] In a preferred embodiment, to ensure precise guidance and no self-rotation of the rotating column 207 during movement, both the connecting block 203 and the fixed seat 202 of the quick-release mechanism 2 are provided with rectangular grooves. The first limiting rod 204 and the second limiting rod 205 have rectangular cross sections that are adapted to the grooves. When the first limiting rod 204 and the second limiting rod 205 slide in the grooves, the inner wall of the grooves contacts the side of the limiting rods smoothly, thereby reliably limiting the self-rotation of the rotating column 207.

[0033] In a preferred embodiment, in order to achieve reliable locking and rapid release of the locking block 201, the integrally formed through groove on the locking block 201 is a through hole structure, and the engaging groove is a U-shaped groove with one end open. When the locking block 201 rotates to the point where the through groove is aligned with the second limiting rod 205, the second limiting rod 205 can pass through without obstruction. When the locking block 201 rotates to the point where the engaging groove is aligned with the second limiting rod 205, the second limiting rod 205 enters the U-shaped groove. At this time, the rotating column 207 can be pulled back to tighten the locking block 201.

[0034] In a preferred embodiment, in order to ensure smooth rotation and effective force transmission between the bolt 206 and the rotating column 207, an annular groove is provided at the end of the shank of the bolt 206, and a retaining ring is provided on the bottom wall of the rotating column 207. The retaining ring is inserted into the annular groove of the bolt 206, thereby forming a rotating connection. The bolt 206 will not come out when rotating, and can stably push or pull the rotating column 207.

[0035] In a preferred embodiment, to ensure the stable installation and smooth movement of the cleaning mechanism 3, the base 305 is fixed to the metal plate of the operating table 1, the slide rail 306 is fixed to the top wall of the base 305 by countersunk screws, and the two ends of the slide rod 302 are fixed to the support seats at both ends of the base 305 by threaded connection.

[0036] In a preferred embodiment, in order to achieve effective power transmission from motor 301 to slider 304, the output shaft of motor 301 is fixedly connected to rotating rod 307 by key connection, and rotating rod 307 and rotating rod 303 are rotatably connected by a bearing pin to reduce rotational friction.

[0037] In a preferred embodiment, in order to ensure the smooth movement and low friction of the slider 304, the slider 304 is slidably mounted on the slide rod 302, and a self-lubricating bearing is installed on the inner wall of the through hole of the slider 304.

[0038] In a preferred embodiment, in order for the vacuum cleaner 308 to move stably with the slider 304 and be supported by the slide rail 306, the bottom of the vacuum cleaner 308 is fixedly connected to the top surface of the slider 304. At the same time, the bottom of the vacuum cleaner 308 is integrally formed or fixedly connected to a slider 304 that matches the cross-sectional shape of the slide rail 306, and the slider 304 is slidably accommodated in the slide rail 306.

[0039] Working principle: When it is necessary to replace the blade 4, first rotate the bolt 206 of the quick-release mechanism 2 clockwise. Due to the threaded engagement, the bolt 206 will move forward along the internal channel formed by the fixed seat 202 and the connecting block 203. Since the end of the bolt 206 is rotatably connected to the bottom wall of the rotating column 207, the translation of the bolt 206 will push the rotating column 207 forward synchronously. During the movement, the limiting rod 1 204 and the limiting rod 205 fixedly connected to the outer wall of the rotating column 207 will slide along the groove opened between the connecting block 203 and the inner wall of the fixed seat 202. The side wall of the groove restricts the rotation of the limiting rod 1 204 and the limiting rod 205, thereby preventing the rotating column 207 from moving forward. 7. Rotation ensures stable linear motion. When the rotating column 207 moves to the predetermined position, the second limit rod 205 completely disengages from the locking groove of the locking block 201. At this time, the locking block 201 is rotated around its own axis so that the through groove on the locking block 201 is aligned with the second limit rod 205. The locking block 201 can then be pulled out from the side. After the locking block 201 is pulled out, the assembly consisting of the bolt 206, the rotating column 207, the first limit rod 204, and the second limit rod 205 is completely pulled out from the channel. At this point, the fixing seat 202 fixed on the blade 4 is completely separated from the connecting block 203 fixed on the output end of the cylinder 5, and the disassembly of the blade 4 can be completed quickly.

[0040] When installing the new blade 4, the reverse operation is performed: insert the connecting block 203 into the fixing seat 202, insert the bolt 206 assembly, insert the locking block 201 and pass it through the slot and limit rod 205, then rotate the locking block 201 so that the engaging slot engages with the limit rod 205, and finally rotate the bolt 206 counterclockwise. The bolt 206 moves backward, and the locking block 201 is pulled backward and tightened by the rotating column 207 and the limit rod 205, and firmly pressed into the limited position of the fixing seat 202. This achieves quick and reliable installation of the blade 4. The whole process does not require complicated tools, greatly shortens the tool changing time, and solves the problems of complicated and inefficient tool changing process.

[0041] During the die-cutting process, the cleaning mechanism 3 is activated, and the motor 301 rotates. The output end of the motor 301 drives the fixedly connected rotating rod 307 to perform circular motion. The rotating rod 307 acts as a crank, driving the slider 304 to reciprocate linearly on the slide rod 302 by rotating the connected rotating rod 303. The vacuum cleaner 308, which is fixedly installed on the slider 304, also reciprocates synchronously. At the same time, the slider 304 structure at the bottom of the vacuum cleaner 308 slides in the slide rail 306, providing stable support and precise guidance for the vacuum cleaner 308, ensuring smooth cleaning. During the reciprocating motion, the vacuum cleaner 308 continuously sucks away the substrate debris generated by the blade 4 when cutting the protective film, effectively preventing debris from accumulating, splashing, or adhering to the gaps of the blade 4. Through this automated cleaning method, the problem of accelerated blade 4 wear, reduced cutting quality, and shortened tool life caused by debris contamination is solved.
