Description
Technical Field
[0001] This utility model relates to the field of film cutting equipment technology, and in particular to a blade adjusting device and a slicing device with anti-disassembly function. Background Technology
[0002] Sheet metal is an indispensable basic material in modern manufacturing. During downstream processing, transportation, and assembly, a protective film is typically applied to its delicate surface to protect it from scratches, contamination, or corrosion. In the final assembly or use stage, this protective film needs to be efficiently and completely peeled off without damaging the sheet metal itself. For this purpose, the industry commonly uses dicing equipment to pre-cut the protective film into specific shapes or segments for easy peeling. To ensure cutting quality, the cutting blades need to be calibrated regularly; therefore, the equipment usually has a dedicated blade adjustment device. Traditional blade adjustment devices are usually directly exposed to the equipment's working environment, presenting the following problems: First, because the blade adjustment device itself has a precise calibration structure, unauthorized personnel (such as operators or cleaning staff) may arbitrarily disassemble the outer casing out of curiosity or misoperation. This may lead to accidental alteration of its internal calibration parameters, contamination or damage to precision components, seriously affecting the accuracy of blade adjustment, and consequently causing cutting quality problems in subsequent mass production. Second, even with intentional maintenance disassembly, the traditional screw-fixed casing is inconvenient to disassemble, and the screws are prone to stripping or loss, affecting maintenance efficiency. Utility Model Content
[0003] To address the shortcomings of existing technologies, this invention provides a blade adjusting device and slicing equipment with anti-disassembly function. It has good anti-disassembly performance and is easy to disassemble for authorized use, thereby protecting the core calibration function and facilitating authorized maintenance.
[0004] This utility model provides a knife adjusting device with anti-tampering function in a first aspect, comprising: a knife adjusting body, wherein the base of the knife adjusting body is provided with at least one connecting channel communicating with the outer circumferential wall of the base; an anti-tampering shell, sleeved on the outside of the base, wherein the inner wall of the anti-tampering shell is provided with a snap-fit groove in the circumferential direction; a driving assembly, disposed in the connecting channel, the driving assembly including a first magnet that is elastically driven, wherein the first magnet extends out to the outside of the base under elastic drive and snaps into the snap-fit groove, thereby fixing the anti-tampering shell to the outside of the knife adjusting body; and a disassembly sleeve, detachably sleeved on the anti-tampering shell, wherein the disassembly sleeve is provided with a second magnet that is magnetically repelled by the first magnet.
[0005] As an improvement to the above solution, the base is provided with three connecting channels evenly arranged around its circumference, and each connecting channel is provided with the driving component.
[0006] As an improvement to the above solution, the driving assembly further includes: a spring, the first end of which is connected to the inner wall of the connecting channel; and a driving block, the first end of which is connected to the second end of the spring, and the second end of which is connected to the first magnet.
[0007] As an improvement to the above solution, the driving block includes: a first driving part connected to the spring, the outer wall of the first driving part being in contact with the inner wall of the connecting channel; a second driving part connected to the first magnet, the outer wall of the second driving part being in contact with the inner wall of the connecting channel; and a connecting part connecting the first driving part and the second driving part, the outer diameter of the connecting part being smaller than the inner diameter of the connecting channel, so that an annular gap is formed between the connecting part and the inner wall of the connecting channel.
[0008] As an improvement to the above solution, the drive assembly further includes a limiting nut, which is fixed to the base, and one end of the limiting nut extends into the annular gap between the connecting part and the inner wall of the connecting channel.
[0009] As an improvement to the above solution, the inner wall of the disassembly sleeve is provided with a mounting hole in the circumferential direction, and the second magnet is fixed in the mounting hole.
[0010] As an improvement to the above solution, the outer diameter of the tamper-proof shell gradually narrows from one side near the base to the other side.
[0011] As an improvement to the above solution, the outer wall of the disassembly sleeve is provided with anti-slip texture.
[0012] As an improvement to the above scheme, both the first magnet and the second magnet are permanent magnets.
[0013] In a second aspect, this utility model provides a slicing device, which is equipped with the aforementioned blade adjusting device with anti-disassembly function.
[0014] The beneficial effects of implementing this utility model are as follows:
[0015] This utility model discloses a knife adjusting device with anti-tampering function. An internally elastically driven first magnet forms a mechanical interlock with the locking groove of the anti-tampering shell, preventing external disassembly without specialized tools. This effectively prevents unauthorized disassembly and protects the precision structure inside the knife adjusting device. Using a dedicated disassembly sleeve, the magnetic repulsion between the second and first magnets within the sleeve drives the first magnet to retract non-contactly, easily releasing the interlock. This process requires no physical contact with the latch, resulting in no wear or scratches, achieving fast and non-destructive authorized disassembly, and providing an excellent maintenance experience. The drive component is integrated into the connection channel, resulting in a very compact overall structure that does not occupy additional space.
[0016] The slicing device of this utility model integrates a blade adjustment device, which gives the device the overall advantages of being tamper-proof and easy to maintain. Attached Figure Description

Detailed Implementation
[0023] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.
[0024] See Figures 1-3 , Figure 1 This is a schematic diagram of the structure of a knife adjusting device with anti-disassembly function in an embodiment of this application; Figure 2 This is an exploded view of the structure of a knife adjusting device with anti-disassembly function in an embodiment of this application; Figure 3This is a partial structural cross-sectional view of a knife adjusting device with anti-tamper function according to an embodiment of this application. As shown in the figure, the device includes: a knife adjusting body 100, the base 110 of the knife adjusting body 100 having at least one connecting channel 111 communicating with the circumferential outer wall of the base 110; an anti-tamper housing 300, sleeved on the outside of the base 110, the inner wall of the anti-tamper housing 300 having a circumferentially provided snap-fit groove 310; a driving assembly 200, disposed in the connecting channel 111, the driving assembly 200 including a first magnet 210 elastically driven, the first magnet 210 extending partially to the outside of the base 110 under elastic drive and snapping with the snap-fit groove 310, so that the anti-tamper housing 300 is fixed to the outside of the knife adjusting body 100; and a disassembly sleeve 400, detachably sleeved on the anti-tamper housing 300, the disassembly sleeve 400 having a second magnet 410 repelling the first magnet 210. In use, by fitting the disassembly sleeve 400 onto the tamper-proof housing 300 and rotating it, the second magnet 410 aligns with the first driving magnet. The repulsive force of the second magnet 410 drives the first driving magnet to compress the elastic drive component and retract it into the connecting channel 111, thereby separating the tamper-proof housing 300 from the knife adjusting body 100. The first magnet 210, driven by internal elasticity, forms a mechanical interlock with the locking groove 310 of the tamper-proof housing 300, which cannot be disengaged from the outside without a special tool, effectively preventing unauthorized disassembly and protecting the precision structure inside the knife adjusting device. Using the dedicated disassembly sleeve 400, the magnetic repulsive force between the second magnet 410 and the first magnet 210 inside it drives the first magnet 210 to retract without contact, easily releasing the locking mechanism. This process requires no physical contact with the latch, resulting in no wear or scratches, achieving fast and non-destructive authorized disassembly, and providing an excellent maintenance experience. The drive component 200 is built into the connecting channel 111, resulting in a very compact overall structure that does not occupy additional space.
[0025] See Figure 4 , Figure 4 This is a structural cross-sectional view of a knife adjusting device with anti-disassembly function in an embodiment of this application;
[0026] Furthermore, in this embodiment, the base 110 has three evenly spaced connecting channels 111 along its circumference, and each connecting channel 111 contains a driving component 200. Based on the principle that three points determine a plane, the three evenly distributed driving components 200 can ensure that the anti-tamper housing 300 is subjected to uniform force, avoiding the shaking or tilting that may occur with single-point or two-point locking, and ensuring the reliability of the fixation. The unlocking process is also smoother: the three points retract synchronously, ensuring that the housing is subjected to balanced force during unlocking, preventing jamming or tilting, and making the disassembly process smoother.
[0027] See Figure 3Furthermore, in this embodiment, the driving assembly 200 further includes: a spring 220, the first end of which is connected to the inner wall of the connecting channel 111; and a driving block 230, the first end of which is connected to the second end of the spring 220, and the second end of which is connected to the first magnet 210. The spring 220 provides a stable elastic force, and the driving block 230 reliably transmits the elastic force to the first magnet 210, ensuring the locking force and consistency.
[0028] See Figure 5 , Figure 5 This is a schematic diagram of the structure of a drive block 230 of a knife adjusting device with anti-disassembly function in an embodiment of this application;
[0029] Specifically, the driving block 230 includes: a first driving part 231 connected to the spring 220, the outer wall of the first driving part 231 fitting against the inner wall of the connecting channel 111; a second driving part 232 connected to the first magnet 210, the outer wall of the second driving part 232 fitting against the inner wall of the connecting channel 111; and a connecting part 233 connected between the first driving part 231 and the second driving part 232, the outer diameter of the connecting part 233 being smaller than the inner diameter of the connecting channel 111, thus forming an annular gap between the connecting part 233 and the inner wall of the connecting channel 111. The annular gap formed between the connecting part 233 and the inner wall of the channel provides necessary space for the movement of the driving block 230, effectively preventing movement jamming caused by processing or assembly errors. The fitting of the first driving part 231 and the second driving part 232 against the inner wall of the channel provides good guidance, ensuring that the first magnet 210 moves in a straight line without deflection, thereby ensuring precise engagement and disengagement with the locking groove 310.
[0030] See Figure 3 Furthermore, in this embodiment, the drive assembly 200 also includes a limiting nut 240, which is fixed to the base 110. One end of the limiting nut 240 extends into the annular gap between the connecting portion 233 and the inner wall of the connecting channel 111. The limiting nut 240 extending into the gap precisely limits the ejection stroke of the drive block 230 under the action of the spring 220, preventing the first magnet 210 from extending too far or even detaching, thus improving the reliability of the mechanism. During disassembly, it also prevents the drive block 230 from moving excessively inward, avoiding damage to the spring 220 due to excessive compression or causing the magnet to collide with the inner wall.
[0031] See Figure 3Furthermore, in this embodiment, the inner wall of the disassembly sleeve 400 is provided with a mounting hole 420 in the circumferential direction, and the second magnet 410 is fixed in the mounting hole 420. Fixing the magnet in a specific position can ensure that the magnetic repulsion force is concentrated and effective when it is aligned with the first magnet 210, thereby improving the efficiency and reliability of unlocking.
[0032] Preferably, the outer diameter of the tamper-proof housing 300 gradually tapers from the side closest to the base 110 to the other side. The tapered design acts as a guide, allowing the disassembly sleeve 400 to easily and accurately fit onto the tamper-proof housing 300, significantly improving ease of operation, especially in environments with poor visibility. The smooth tapered surface makes it difficult to clamp with ordinary tools (such as pipe wrenches), increasing the difficulty of unauthorized disassembly to some extent.
[0033] Preferably, the outer wall of the disassembly sleeve 400 is provided with anti-slip texture. This increases the friction between the hand and the sleeve, making it easier to rotate or insert / remove the sleeve 400.
[0034] Preferably, both the first magnet 210 and the second magnet 410 are permanent magnets. They provide a strong and stable magnetic field without the need for external power supply, ensuring the durability and reliability of the locking and unlocking forces. The system has a simple structure and no risk of failure due to power outages.
[0035] This embodiment provides a slicing device in a second aspect, the slicing device being equipped with the aforementioned blade adjusting device with anti-disassembly function.
[0036] As can be seen from the above, the knife adjusting device with anti-tamper function in this utility model forms a mechanical interlock between the internally elastically driven first magnet and the snap-fit groove of the anti-tamper shell. It cannot be disengaged from the outside without a special tool, effectively preventing unauthorized disassembly and protecting the precision structure inside the knife adjusting device. Using a special disassembly sleeve, the magnetic repulsion between the second and first magnets inside the sleeve drives the first magnet to retract non-contactly, easily releasing the snap-fit. This process requires no physical contact with the latch, resulting in no wear or scratches, achieving fast and non-destructive authorized disassembly, and providing an excellent maintenance experience. The drive component is built into the connection channel, making the overall structure very compact and not occupying extra space.
[0037] The slicing device of this utility model integrates a blade adjustment device, which gives the device the overall advantages of being tamper-proof and easy to maintain.
[0038] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
