Abstract
Description
Technical Field
[0001] This invention relates to the field of cutting equipment technology, and in particular to a knife-fixing structure and a knife-fixing device that are easy to remove. Background Technology
[0002] Currently, to facilitate the assembly of sheet materials, workers often need to use a scribing machine to scratch the protective film on the surface of the sheet materials so that the protective film can be removed later. The scribing machine mainly controls the movement of the blade holder and the scribing blade located inside the blade holder to create scratches of a predetermined depth.
[0003] However, to ensure a stable connection, the current connection structure between the blade sleeve and the cutting blade is too complex, making it difficult to disassemble and replace the cutting blade. It requires a lot of time for staff to complete the disassembly process, which does not improve processing efficiency.
[0004] Furthermore, during the film-cutting process, the cutting blade of the existing film-cutting machine is prone to rotation, which greatly affects the stability and accuracy of the cuts and is not conducive to ensuring processing precision. Summary of the Invention

The mounting sleeve is provided with a first mounting channel, and the blade sleeve enters the first mounting channel from one end of the first mounting channel, and the blade sleeve can reciprocate along the first mounting channel.
[0007] The blade sheath is provided with a second mounting channel and a positioning cavity. The positioning cavity and the second mounting channel are offset from each other and partially connected. The dicing knife includes a first handle, a blade body and a first blade head that are interconnected in sequence. There is a notch between the first handle and the blade body so that the blade body is located in the second mounting channel. The first handle is locked in the positioning cavity, and the second mounting channel is connected to the outside so that the first blade head is exposed through the second mounting channel.
[0008] The side of the blade sheath is provided with a first disassembly hole that communicates with the second mounting channel. The first disassembly hole is arranged along the length direction of the blade sheath. The blade removal component passes through the first disassembly hole into the second mounting channel and abuts against the connection between the blade body and the first blade handle, so that the dicing blade is removed from the blade sheath.
[0009] Preferably, the side of the blade sheath is further provided with a second disassembly hole that communicates with the positioning cavity. The second disassembly hole is arranged along the length direction of the blade sheath, and the position of the second disassembly hole is offset from the position of the first disassembly hole. The blade removal component passes through the second disassembly hole into the positioning cavity and abuts against the end of the first blade handle.
[0010] Preferably, the positioning cavity has an arc-shaped hole at the edge near the bottom, and the positioning cavity is connected to the second mounting channel through the arc-shaped hole. The first tool holder has a flat part and an arc-shaped part interconnected along its circumference. The flat part abuts against the bottom of the positioning cavity, and the arc-shaped part abuts against the arc-shaped hole.
[0011] Preferably, at least part of the end of the second mounting channel is located within the positioning cavity, and the end of the second mounting channel is provided with a blocking surface that abuts against the connection between the blade and the first handle.
[0012] Preferably, an adjusting sleeve is fitted at the end of the blade sheath, and the adjusting sleeve is threadedly connected to the blade sheath so that the adjusting sleeve can reciprocate along the blade sheath, thereby allowing the adjusting sleeve to avoid or cover the first blade head.
[0013] Preferably, a limiting sleeve is provided at one end of the first installation channel, the blade sleeve passes through the limiting sleeve, and the side of the blade sleeve is provided with an outwardly protruding limiting part, the limiting part abutting against the limiting sleeve as the blade sleeve moves.
[0014] Preferably, the easy-to-remove fixed blade structure further includes a drive motor, which enters the first mounting channel from the other end of the first mounting channel, and the other end of the blade sleeve is provided with a pushing part, and the drive motor is connected to the pushing part.
[0015] Preferably, the tool disassembly component includes an interconnected second tool holder and a second tool head. The second tool head has a first plane, a second plane, a third plane, and a first bevel surface that are interconnected in sequence along its circumference. The first plane, the second plane, and the first bevel surface are all directly connected to the second tool holder, and the third plane and the second tool holder are connected through the second bevel surface.
[0016] Preferably, the width of the first plane gradually decreases from the connection point between the first plane and the second shank towards the end of the second blade tip, the width of the second chamfered surface gradually decreases from the connection point between the second chamfered surface and the second shank towards the third plane, the third plane and the second chamfered surface are arranged at an angle to each other, and the width of the third plane gradually decreases from the connection point between the third plane and the second chamfered surface towards the end of the second blade tip.
[0017] On the other hand, the present invention provides a knife-fixing device, characterized in that it includes the above-described knife-fixing structure that is easy to remove.
[0018] Implementing this invention has the following beneficial effects:
[0019] The present invention provides a first installation channel within the mounting sleeve, and the cutter sleeve enters the first installation channel from one end of the first installation channel. The cutter sleeve can reciprocate along the first installation channel to adjust the dicing depth and ensure processing accuracy.
[0020] The blade sheath includes a second mounting channel and a positioning cavity. The positioning cavity and the second mounting channel are offset from each other but partially connected. The dicing blade includes a first blade handle, a blade body, and a first blade head, which are sequentially interconnected. A notch is provided between the first blade handle and the blade body to position the blade body within the second mounting channel, serving as a limiting mechanism. The first blade handle is engaged within the positioning cavity to achieve positioning and anti-rotation functions, ensuring a stable connection and preventing the dicing blade from rotating during processing, further guaranteeing processing accuracy. Furthermore, the second mounting channel communicates with the outside, allowing the first blade head to be exposed through the second mounting channel for dicing.
[0021] Furthermore, to achieve the function of quick removal, the side of the blade sheath is provided with a first disassembly hole that communicates with the second mounting channel. The first disassembly hole is arranged along the length direction of the blade sheath to provide disassembly space. In addition, since there is a notch between the blade body and the first blade handle, the blade removal component passes through the first disassembly hole into the second mounting channel and abuts against the connection between the blade body and the first blade handle, thereby pushing the dicing blade out of the blade sheath, realizing the quick removal function, and thus improving processing efficiency.

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.
[0030] Combination Figures 1 to 7 According to one embodiment of the present invention, a knife fixing structure that is easy to remove is provided, including a mounting sleeve 1, a knife sleeve 2, a film cutting knife 3 and a knife removal component 4;
[0031] The present invention provides a first installation channel 11 within the installation sleeve 1. The blade sleeve 2 enters the first installation channel 11 from one end of the first installation channel 11, and the blade sleeve 2 can reciprocate along the first installation channel 11 to adjust the dicing depth and ensure processing accuracy.
[0032] The blade sheath 2 is provided with a second mounting channel 21 and a positioning cavity 22. The positioning cavity 22 and the second mounting channel 21 are staggered and partially connected. The dicing blade 3 includes a first blade handle 31, a blade body 32, and a first blade head 33 connected in sequence. A notch 34 is provided between the first blade handle 31 and the blade body 32 so that the blade body 32 is located in the second mounting channel 21, which serves as a limiting function. The first blade handle 31 is locked in the positioning cavity 22 to achieve positioning and anti-rotation functions, ensuring a stable connection and preventing the dicing blade 3 from rotating during the processing, thus further ensuring processing accuracy. Furthermore, the second mounting channel 21 is connected to the outside so that the first blade head 33 is exposed through the second mounting channel 21 to realize the dicing function.
[0033] Furthermore, to achieve the function of quick removal, the side of the blade sleeve 2 is provided with a first disassembly hole 23 that communicates with the second mounting channel 21. The first disassembly hole 23 is arranged along the length direction of the blade sleeve 2 to provide disassembly space. In addition, since there is a notch 34 between the blade body 32 and the first blade handle 31, the blade removal component 4 passes through the first disassembly hole 23 into the second mounting channel 21 and abuts against the connection between the blade body 32 and the first blade handle 31, thereby pushing the dicing blade 3 to detach from the blade sleeve 2, realizing the quick removal function and thus improving processing efficiency.
[0034] Furthermore, when the blade 32 is too close to the positioning cavity 22, it may result in insufficient space for the disassembly component 4 to push the connection between the blade 32 and the first tool holder 31. To solve this problem, the side of the tool sleeve 2 is also provided with a second disassembly hole 24 that communicates with the positioning cavity 22. The second disassembly hole 24 is arranged along the length direction of the tool sleeve 2, and the position of the second disassembly hole 24 is offset from the position of the first disassembly hole 23 to ensure structural stability. The disassembly component 4 passes through the second disassembly hole 24 into the positioning cavity 22 and abuts against the end of the first tool holder 31 to further achieve a quick disassembly effect and further improve processing efficiency.
[0035] Preferably, to achieve positioning and anti-rotation functions, the positioning cavity 22 is provided with an arc-shaped hole 221 near the bottom edge. The positioning cavity 22 is partially connected to the second mounting channel 21 through the arc-shaped hole 221. The first tool holder 31 is provided with a flat part 311 and an arc-shaped part 312 interconnected along its circumference. The flat part 311 abuts against the bottom of the positioning cavity 22, and the arc-shaped part 312 abuts against the arc-shaped hole 221. The arc-shaped hole 221 and the bottom of the positioning cavity 22 cooperate with the first tool holder 31 to eliminate the rotatable space of the first tool holder 31, avoid the rotation of the dicing knife 3 during the processing, and ensure processing accuracy.
[0036] More preferably, at least part of the end of the second mounting channel 21 is located within the positioning cavity 22 to further ensure the connection effect, and the end of the second mounting channel 21 is provided with a blocking surface 211, which abuts against the connection between the blade 32 and the first handle 31 to play a blocking role.
[0037] On the other hand, combining Figures 1 to 5 To achieve the adjustment function, an adjustment sleeve 5 is fitted onto the end of the blade sleeve 2. The adjustment sleeve 5 is threadedly connected to the blade sleeve 2, allowing the adjustment sleeve 5 to reciprocate along the blade sleeve 2, thereby allowing the adjustment sleeve 5 to avoid or cover the first blade head 33. Furthermore, by setting the adjustment sleeve 5, the exposed area of the first blade head 33 can be flexibly and quickly adjusted to flexibly cope with uneven board surfaces, while preventing blade cap marks from being produced during film slicing.
[0038] Preferably, in order to serve as a limiting device, a limiting sleeve 12 is provided at one end of the first mounting channel 11. The blade sleeve 2 passes through the limiting sleeve 12 and can reciprocate along the limiting sleeve 12. The side of the blade sleeve 2 is provided with an outwardly protruding limiting part 25. The limiting part 25 abuts against the limiting sleeve 12 as the blade sleeve 2 moves, so as to prevent the blade sleeve 2 from detaching from the mounting sleeve 1 due to excessive movement.
[0039] More preferably, to achieve the driving function, the easily removable fixed blade structure also includes a drive motor 6, which enters the first mounting channel 11 from the other end of the first mounting channel 11, and the other end of the blade sleeve 2 is provided with a pushing part 26, and the drive motor 6 is connected to the pushing part 26.
[0040] In addition, combined again Figures 1 to 7 To achieve the disassembly function, the disassembly component 4 includes an interconnected second blade handle 41 and a second blade head 42. The second blade head 42 is provided with a first plane 421, a second plane 422, a third plane 423, and a first oblique cut surface 424 that are interconnected in sequence along its circumference. The first plane 421, the second plane 422, and the first oblique cut surface 424 are all directly connected to the second blade handle 41. The third plane 423 and the second blade handle 41 are connected by a second oblique cut surface 425, so that the disassembly component 4 can better pass through the first disassembly hole 23 and / or the second disassembly hole 24, and better abut against the dicing knife 3, thereby improving the applicability and wide application of the disassembly component 4.
[0041] Furthermore, the width of the first plane 421 gradually decreases from the connection point between the first plane 421 and the second handle 41 towards the end of the second blade head 42, and the width of the second chamfered surface 425 gradually decreases from the connection point between the second chamfered surface 425 and the second handle 41 towards the third plane 423. The third plane 423 and the second chamfered surface 425 are set at an angle to each other, and the width of the third plane 423 gradually decreases from the connection point between the third plane 423 and the second chamfered surface 425 towards the end of the second blade head 42, so as to further facilitate the disassembly piece 4 to better penetrate into narrow and complex environments and ensure quick disassembly efficiency.
