Description

Technical Field

[0001] This utility model relates to the field of textile testing technology, and more specifically, to a textile sample cutting machine. Background Technology

[0002] Currently, in the textile testing industry, it is common practice to cut a whole piece of fabric into smaller samples of different sizes before conducting sample testing to meet the requirements of various testing items. For example, tests such as strength testing, abrasion resistance testing, and air permeability testing have different requirements for sample size; some tests require the same size, while others require different sizes. Therefore, it is necessary to cut the same piece of fabric multiple times to obtain multiple sets of samples with different specifications.

[0003] Existing cutting methods primarily rely on manual operation, with common tools including scissors and some single-size press-type cutters (e.g., disc samplers). Scissors are suitable for cutting any shape, but are inefficient and require significant manual labor. Press-type cutters (circular samplers) are typically used for cutting circular samples; while they can improve efficiency to some extent, the dimensions cut by circular samplers are fixed and cannot meet the requirements for cutting samples of various sizes. When the testing workload is large, frequent changes of samplers lead to low cutting efficiency and increase the operator's workload and time costs.

[0004] Furthermore, existing textile testing cutting devices generally have a simple structure and lack modular design, making it impossible to flexibly and quickly switch between multiple sizes on a single device. This makes it difficult to meet the efficiency and convenience requirements of testing institutions in multi-specification cutting. Therefore, there is an urgent need to provide a modular textile cutting machine that can integrate multiple cutting heads and achieve rapid switching, in order to reduce manual labor intensity and improve cutting efficiency and adaptability.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings.

Example

[0033] This embodiment discloses a textile sample cutting machine, such as... Figure 1-7 As shown, the sample cutting machine includes: a support 1, a transmission mechanism 2, a protective shell 3, a rotating shaft 4, a base shaft 5, and a cutting head 6; The bracket 1 is used to fix the transmission mechanism 2; The upper end of the protective shell 3 is connected to the transmission mechanism 2; the transmission mechanism controls the up and down movement of the protective shell 3. The base axis 5 is a polyhedral prism; The lower end of the protective shell 3 is designed with an opening. The rotating shaft 4 passes through the center of the base shaft 5 and is connected to the base shaft 5, and drives the base shaft 5 to rotate coaxially; The base shaft 5 is rotatably mounted in the protective shell 3 in the horizontal direction via the rotating shaft 4, and one of the cylindrical surfaces of the base shaft 5 is lower than the opening surface of the protective shell 3; The cutter head 6 is mounted on the cylindrical surface of the base shaft 5 along the axial direction of the base shaft 5.

[0034] It should be noted that current sample cutting mainly relies on scissors or single-size press-type cutters. When faced with multiple sizes and quantities of cutting tasks on the same piece of fabric, it is necessary to frequently change different sized cutters, resulting in numerous steps and low efficiency. Therefore, the cutting device should be designed to enable rapid switching between multiple sizes without disassembling the cutters. In this embodiment, multiple sizes of cutters are integrated within the same module, and switching is accomplished through a rotation / selection mechanism. In this embodiment, different cutters 6 are mounted on different cylindrical surfaces of the base shaft 5. During cutting, simply rotating the rotating shaft 4 to rotate the base shaft 5 to another cylindrical surface is sufficient to switch between different cutters 6.

[0035] In this embodiment, before cutting, different sized cutter heads 6 can be installed on the cylindrical surface of the base shaft 5 according to production needs. If one base shaft 5 cannot accommodate all the cutter heads 6, multiple base shafts 5 can be set, or base shafts of different sizes can be set. Then, the cutter heads 6 can be installed on each cylindrical surface of the base shaft 5. During cutting, if the cutter head 6 at the bottom of the base shaft 5 cannot meet the cutting requirements, the rotating shaft 4 can be rotated to switch the cutter head. If there is no cutter head 6 on the base shaft 5 that meets the requirements, the base shaft can be removed and replaced with a base shaft with a suitable cutter head 6.

[0036] It should be noted that the cylindrical surface of the base axis 5 in this embodiment is the side surface of the polyhedral prism, which is the surface set along the axial direction of the prism.

[0037] It should be noted that, to ensure operational safety, when multiple sizes of cutting heads are integrated within the protective shell 3, a protective shell is required to prevent operators from being injured by the blades during use and replacement. In this embodiment, a protective shell 3 is provided, and the cutting head 6 is housed within the protective shell 3, effectively protecting the operator's safety during cutting.

[0038] In this embodiment, as Figure 2 As shown, the support 1 includes a base plate 11 and a frame 12; The frame 12 is mounted on the base plate 11; The transmission mechanism 2 is mounted on the frame 12.

[0039] It should be noted that, in this embodiment, the base plate 11 is the foundation of the sample cutting machine described in this embodiment, used to bear the weight of all components and to provide a flat placement reference surface for the material to be cut.

[0040] Furthermore, the base plate 11 described in this embodiment is also provided with bolt holes, which allow it to be fixed on the workbench to prevent the equipment from moving during cutting.

[0041] In this embodiment, the transmission mechanism 2 includes a rocker arm 21, a first connecting shaft 22, a second connecting shaft 23, a first arm 24, a second arm 25, an arm shaft 26, and a pressure rod 27. The frame 12 includes a first panel 121 and a second panel 122; The first panel 121 and the second panel 122 are parallel to each other and are both vertically fixed to the base plate 11; The first connecting shaft 22 passes perpendicularly through the first panel 121 and the second panel 122; The rocker arm 21 is arranged radially at one end of the first connecting shaft 22, and the rocker arm 21 is used to drive the first connecting shaft 22 to rotate. The first arm 24, the second arm 25, the arm shaft 26, and the second connecting shaft 23 are disposed between the first panel 121 and the second panel 122; One end of the first arm 24 is fixed to the middle of the first connecting shaft 22 along the radial direction of the first connecting shaft 22; The other end of the first boom 24 is hinged to one end of the boom shaft 26; the other end of the boom shaft 26 is hinged to one end of the second boom 25. The other end of the second arm 25 is provided with a through hole that matches the second connecting shaft 23; The second connecting shaft 23 passes through the through hole on the second arm 25 and is fixed between the first panel 121 and the second panel 122; The other end of the second arm 25 is connected to the upper end of the pressure rod 27; The lower end of the pressure rod 27 is connected to the upper end of the protective shell 3; The included angle between the first arm 24 and the second arm 25 is less than 90°.

[0042] It should be noted that the first panel 121 and the second panel 122 described in this embodiment are the main supporting components of the cutting machine. The first panel 121 and the second panel 122 are symmetrically distributed on the base plate 11 or on both sides of the base plate 11, and are used to support the weight of components such as the transmission mechanism and the cutting head.

[0043] The first connecting shaft 22 and the second connecting shaft 23 form a support structure. The first connecting shaft 22 and the second connecting shaft 23 work together to prevent the equipment from tilting and enhance its torsional resistance during manual cutting.

[0044] It should be noted that the rocker arm 21 and the first connecting shaft 22 form an L-shaped rod, which serves as the input component for manual power. The human force applied to the rocker arm is converted into a downward driving force, which is transmitted to the subsequent transmission mechanism 2.

[0045] The first arm 24, the second arm 25, and the arm shaft 27 efficiently convert the downward force of the rocker arm 21 into the downward force of the base shaft 5. This ensures that the cutter head 6 presses down synchronously during cutting, avoiding deviation.

[0046] Different cutter heads 6 are mounted on different cylindrical surfaces of the base shaft 5. The rotating shaft 4 is a shaft that perpendicularly penetrates the large base shaft 5. Its core function is to realize the rotational switching of the cutter heads; by rotating it, different cutter heads can be rotated to the working position.

[0047] It should be noted that, in this embodiment, the transmission mechanism further includes a third connecting shaft 28 and a fourth connecting shaft 29; the first arm 24 and the arm shaft 26 are hinged together by the third connecting shaft; the second arm 25 and the arm shaft 26 are hinged together by the fourth connecting shaft.

[0048] It should be noted that, as a specific embodiment, the first panel 121 and the second panel 122 in this embodiment are "7"-shaped panels, including a horizontal part and a vertical part. The horizontal part is mainly to facilitate the vertical movement of components such as the protective shell 3. If it is not set to a "7" shape, other shapes are also acceptable. For example, if two square plates are set, then if the size of the protective shell 3, the pivot 4, the base shaft 5, etc. is too large, then the distance between the first panel 121 and the second panel 122 needs to be set accordingly to be larger.

[0049] In this embodiment, the height of the second link shaft 23 is higher than that of the first link shaft 22.

[0050] It should be noted that in this embodiment, the height of the second connecting shaft 23 is set higher than that of the first connecting shaft 22 to facilitate the operation of the transmission mechanism 2.

[0051] In this embodiment, the second arm 25 includes a first connecting rod 251 and a second connecting rod 252; A through hole on the second arm 25 that matches the second connecting shaft 23 is provided at the connection between the first connecting rod 251 and the second connecting rod 252; One end of the first connecting rod 251 is connected to the arm shaft 26, and the other end is connected to one end of the second connecting rod 252; the other end of the second connecting rod 252 is connected to the upper end of the pressure rod 27. The included angle between the first link 251 and the second link 252 is greater than 90°.

[0052] It should be noted that, since the angle between the first arm 24 and the second arm 25 is less than 90°, and the angle between the first connecting rod 251 and the second connecting rod 252 is greater than 90°, the second connecting rod can be in a horizontal or nearly horizontal state, which is beneficial for driving the pressure rod 27 downward.

[0053] In this embodiment, the bracket includes a fixing rod 7; the fixing rod 7 is disposed between the first panel 121 and the second panel 122.

[0054] It should be noted that in this embodiment, the fixing rod 7 is used to strengthen the fixation between the first panel 121 and the second panel 122. At the same time, most of the components of the transmission mechanism 2, since they are core transmission components, are located between the first panel 121 and the second panel 122.

[0055] In this embodiment, the base axis 5 is a triangular prism.

[0056] It should be noted that, as a specific embodiment, since textile testing and sample cutting require compatibility with six different sizes of cutting tools, to reduce the overall size of the integrated system, the design combines three sizes of cutting tools into one module. Specifically, three cutting heads (6) are respectively positioned on the three faces of a triangular prism, forming two rotatable and switchable integrated cutting tool modules. Furthermore, both of these integrated cutting tool modules can be disassembled and replaced, facilitating quick switching and maintenance by operators according to different needs.

[0057] Through extensive testing and practical application, this embodiment found that using three cutter heads per group is most suitable. In actual operation, using three cutter heads per group maximizes work efficiency. Therefore, a triangular prism is the optimal base shaft.

[0058] In this embodiment, the middle part of the rotating shaft 4 is an irregularly shaped cylinder; the two ends of the rotating shaft 4 that are in contact with the protective shell 3 are cylinders. The base shaft 5 is provided with a through hole along its axis that matches the irregularly shaped column in the middle of the rotating shaft 4.

[0059] It should be noted that the middle part of the rotating shaft 4 is an irregularly shaped column, which can effectively drive the base shaft 5 to rotate when the rotating shaft 4 rotates. The two ends of the rotating shaft 4 and the base of the protective shell 3 are cylindrical, which is conducive to the rotation of the rotating shaft 4 and is not affected by the protective shell 3, thus preventing the rotating shaft 4 from being unable to rotate.

[0060] In this embodiment, the sample cutting machine also includes a nut 8; One end of the rotating shaft 4 is provided with a rotating handle, and the other end is provided with a thread that matches the nut 8.

[0061] It should be noted that in this embodiment, by setting a rotating handle at one end of the rotating shaft 4 and a nut 8 at the other end, it is convenient to disassemble and replace the rotating shaft 4, and also convenient to replace the base shaft 5 and the cutter head 6.

[0062] The cutting machine includes at least two base shafts 5; each base shaft 5 has a different size. Each base spindle 5 is equipped with three different cutter heads 6.

[0063] It should be noted that in actual use, two base spindles 5 are generally used to meet basic production needs. The two base spindles 5 are one large and one small, and can accommodate 6 different models and sizes of cutter heads 6.

[0064] As a specific embodiment, assuming the rotating shaft 4, base shaft 5, cutter head 6, protective shell 3, and nut 8 are considered as a cutter head module, then within the cutter head module, the irregular cylindrical structure in the middle of the rotating shaft 4, the position of the nut 8, the appearance of the protective shell 3, and the different models of cutter heads 6, etc., are as follows: Figure 3 As shown.

[0065] Furthermore, in practical applications, the cutting heads in this embodiment include: a 125*125 cutting head: used for cutting large square materials, with a hardened cutting edge to ensure smooth edges; a concave cutting head: used for cutting non-linear or irregularly shaped materials, such as curved edges or concave parts; a 100*150 cutting head: used for cutting medium-sized rectangular materials, with an angled cutting edge design to reduce manual cutting resistance; a 125*125 cutting head: used for cutting narrow, long strips of material, with protective edges on both sides to prevent the material from warping during cutting; a 50*50 cutting head: used for cutting micro-square materials, with a thin cutting edge design to reduce material deformation; and a 40*140 cutting head: used for cutting small rectangular materials, with rounded corners to avoid sharp material edges.

[0066] This embodiment employs a dual-module, disassembled and integrated design, categorizing six types of cutting heads into "large-size / special-shape" 125*125, concave, and 100*150 cutting heads, and "small-size" 125*125, 50*50, and 40*140 cutting heads. These are then integrated onto the base shaft corresponding to the large-size cutting head mounted on a large base shaft, and the base shaft corresponding to the small-size cutting head mounted on a small base shaft, respectively. The two modules are symmetrically assembled between the first panel 121 and the second panel 122 of the frame, effectively avoiding the volume redundancy problem caused by integrating all cutting heads into a single module. Furthermore, any module can be disassembled individually, facilitating cutting head maintenance or module replacement.

[0067] In the specific implementation process, pressing down the rocker arm 21 by hand causes the first connecting shaft 22 to rotate, which in turn causes the first arm 24 to rotate. Since the first arm 24 is hinged to the lower end of the arm shaft, it lifts the arm shaft 26. The upper end of the arm shaft 26 causes one end of the first connecting rod 251 to rise. Since the second arm 25 is rotatably connected to the bracket 1 through the second connecting shaft 22, when the end of the second arm 25 connected to the arm shaft 26 rises, it causes the second arm 25 to rotate along the second connecting shaft 22, which in turn causes the end of the second arm 25 connected to the pressure rod 27 to press down. The pressing rod 27 causes the protective shell 3 to move downward. The protective shell 3 drives the base shaft 5 to move downward through the rotating shaft 4. The downward movement of the base shaft 5 drives the cutter head 6 to move downward to complete the material cutting.

[0068] This embodiment completely replaces the traditional methods of "scissor cutting" or "single-size press-type cutter". When faced with multiple sizes and quantities of cutting tasks on the same piece of fabric, the operator does not need to frequently disassemble and change different sizes of cutter heads. He only needs to rotate the shaft 4 to switch the cutter head 6 and then pull down the rocker arm 21 to complete the cutting. This greatly shortens the cutting time of a single piece of fabric and significantly improves the overall cutting efficiency.

[0069] This embodiment, through its structure of "protective shell fully covering the blade head + pressure bar assisting in blocking the gap," physically isolates all sharp blade heads inside the protective shell 3, leaving only the opening required for cutting. This effectively ensures the operator's safety. Example

[0070] like Figure 4-7 As shown, this embodiment includes all the technical features of embodiment 1, which will not be repeated here. The difference from embodiment 1 is that in this embodiment, an elastic structure 9 is also provided between the pressure rod 27 and the protective shell 3. The elastic force of the elastic structure 9 is adjustable; By adjusting the elastic force of the elastic structure 9, the pressure of the pressure rod 27 on the protective shell 3 can be adjusted.

[0071] In this embodiment, the elastic structure 9 includes a connecting sleeve 91, a pressure-bearing component 92, and a pressure-adjusting spring 95; The lower end of the pressure rod 27 is provided with an external thread, and the connecting sleeve 91 is provided with an internal thread that matches the pressure rod 27; The pressure rod 27 and the connecting sleeve 91 are connected by threads; The two ends of the adjusting spring 95 are connected to the connecting sleeve 91 and the pressure bearing component 92, respectively.

[0072] In this embodiment, the lower part of the pressure rod 27 is hollow; The pressure-bearing component 92 is provided with a guide rod 921 that matches the hollow center of the pressure rod 27. The guide rod 921 is sleeved inside the hollow of the pressure rod 27; The adjusting spring 95 is coaxially sleeved on the outside of the guide rod of the pressure rod 27 and the pressure bearing member 92.

[0073] In this embodiment, the top of the guide rod 921 is provided with a protrusion 922; The lower end of the pressure rod 27 is provided with a limiting member 271; The limiting member 271 restricts the protrusion 922 from disengaging from the pressure rod 27 when it moves downward within the pressure rod 27.

[0074] It should be noted that in this embodiment, an elastic structure 9 is installed between the transmission mechanism 2 and the protective shell 3 to adjust the downward pressure, thereby protecting the cutter head 6. Various types of elastic structures 9 can be used, including one where a rotating disc presses down on the elastic structure 9, allowing for pressure adjustment for different fabrics and thus better cutting. Specifically: the pressure rod 27 and the connecting sleeve 91 are connected by threads; the elastic element of the elastic structure 9 is selected as a pressure adjusting spring 95, used to connect the connecting sleeve 91 and the pressure bearing member 92; the pressure bearing member 92 receives the elastic force of the pressure adjusting spring 95 and transmits the force to the cutter head 6; the pressure bearing member 92 extends with a guide rod 921, the top of which has a protrusion 922, allowing the guide rod 921 to be engaged in the pressure rod 27 like a piston (the lower part of the pressure rod has a limiting member 271), ensuring that the pressure bearing member 92 and the pressure rod 27 can only move relative to each other in the vertical direction and limiting the distance of relative movement. Force transmission process: The transmission mechanism 2 transmits pressure to the pressure rod 27. The pressure rod 27 connects to the connecting sleeve 91, and the force is transmitted from the pressure rod 27 to the connecting sleeve 91. The connecting sleeve 91 transmits the force to the elastic structure 9, the elastic structure 9 transmits the force to the bearing member 92, and the bearing member 92 transmits the force to the connected cutter head 6. The compression of the elastic structure 9 can be changed by rotating the connecting sleeve 91, thereby changing the spring force and thus altering the force transmitted to the bearing member 92. This ensures that the maximum downward pressure on the cutter head is equal to the maximum spring force, thus limiting the force and protecting the cutter head. The maximum pressure value can also be adjusted by rotating the connecting sleeve 91.

[0075] In addition, the elastic mechanism 9 described in this embodiment is also provided with a gasket 93 and a piston hole 94. The gasket is disposed between the pressure rod 27 and the connecting sleeve 91, which can reduce the wear between the pressure rod 27 and the connecting sleeve 91 when rotating. The piston hole 94 is a through hole opened on the protrusion 922 to ensure that the air pressure inside and outside the piston is consistent. The piston hole 94 can be axially penetrating the entire guide rod 921 and the protrusion 922, or it can be opened at a position where the protrusion 922 and the guide rod 922 are not in contact.

[0076] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
